    121 
    122     @ref orxonox::Notification "Notifications" are short messages, that can be sent from anywhere in Orxonox and then are displayed on the screen to inform the user about some occurence he has to know about. Such an occurence could be, that he just shot and killed his Archnemesis Overlord3, that he just got a new Pickup or that he received a Quest and needs to have a look at the Quest-Menu.
    123 
    124     @section NotificationsUsage Usage
    125     Let's very briefly talk about what you have to do to either send @ref orxonox::Notification "Notifications" from some part of Orxonox or display Notifications on your screen.
    126 
    127     @subsection NotifictionsSending Sending notifications
    128     Sending a new @ref orxonox::Notification "Notification" from (almost) anywhere in Orxonox is fairly easy.
    129     You first have to decide on a message, it shouldn't be too long but be long enough to get your point accross.
    130     Then you have to decide on a sender. The sender is a string by which the different @ref orxonox::NotificationQueue "NotificationQueues" (the entities that display the @ref orxonox::Notification "Notifications") can decide whether they should display the @ref orxonox::Notification "Notification" or not. So the sender is some string that identifies a group of @ref orxonox::Notification "Notifications" that have something in common or some entity that is sending them. For example: All @ref orxonox::Notification "Notifications" sent by any part of the Questsystem have "questsystem" as sender and thus we could create a @ref orxonox::NotificationQueue "NotificationQueue" that only displays @ref orxonox::Notification "Notifications" from the Questsystem, but more to that later.
    131     And lastly you have to decide to whom you want to send this @ref orxonox::Notification "Notification". You have to get the clientId of the intended recipient (e.g. trough a @ref orxonox::PlayerInfo "PlayerInfo") or you only send the @ref orxonox::Notification "Notification" locally, either by setting the clientId to Host::getPlayerID() or by setting the variable 'isLocal' to true, and setting clientId to what ever you want, since it will be ignored.
    132     Once you have decided all that you can send the Notification by calling:
    133     @code
    134     NotificationManager::sendNotification(message, clientId, sender, isLocal); // isLocal = false can be ommitted since that is the default value.
    135     @endcode
    136 
    137     @subsection NotificationsDisplay Displaying notifications
    138     Displaying @ref orxonox::Notification "Notifications" is even easier, all you need to do is to load the NotificationLayer in the level, where you want @ref orxonox::Notification "Notifications" displayed. You can either do this manually by executing the following command in the console:
    139     @code
    140     showGUI NotificationLayer false true
    141     @endcode
    142     Or automatically, by adding a @ref orxonox::Script "Script" to the levelfile that does it for you:
    143     @code
    144     <Script code="showGUI NotificationLayer false true" needsGraphics="true" />
    145     @endcode
    146 
    147     If you want to change the way the @ref orxonox::Notification "Notifications" are displayed, you can enter the (at this point rather rudimentary) edit mode and add new @ref orxonox::NotificationQueue "NotificationQueues" or change position and properties of the existing ones, by executing the following command in the console:
    148     @code
    149     enterEditMode
    150     @endcode
    151 
    152     @section NotificationsTechincalDetails Technical details
    153     The Notifications module has three major parts that interact with each other. First there is the @ref orxonox::NotificationQueue "NotificationQueue", this is the entity that (logically, not effectively) displays @ref orxonox::Notification "Notifications" according to some rules, then there is the NotificationLayer, which is the GUI which (actually) displays @ref orxonox::Notification "Notifications" by visualizing the @ref orxonox::NotificationQueue "NotificationQueues" and as a result also the @ref orxonox::Notification "Notifications", that are displayed by the respective @ref orxonox::NotificationQueue "NotificationQueues" and lastly there is the @ref orxonox::NotificationManager "NotificationManager", which connects these two.
    154 
    155     @subsection NotificationQueue NotificationQueue
    156     The @ref orxonox::NotificationQueue "NotificationQueue" is the entity, that (as said earlier) logically displays @ref orxonox::Notification "Notifications". Furthermore a @ref orxonox::NotificationQueue "NotificationQueue" displays only a subset of all the @ref orxonox::Notification "Notifications". The parameters that reduce the range of displayed @ref orxonox::Notification "Notifications" are:
    157     - @b senders The senders, the set of targets of a @ref orxonox::NotificationQueue "NotificationQueue" is the set of senders a @ref orxonox::NotificationQueue "NotificationQueue" displays  @ref orxonox::Notification "Notifications" from. E.g. If one would set the senders to "questsystem" then only  @ref orxonox::Notification "Notifications" from the Questsystem would be displayed in that particular queue. If you set senders to "all" then all Notifications will be displayed. Different senders can be concatinated with commas.
    158     - @b size The size specifies how many @ref orxonox::Notification "Notifications" are displayed at the most, if there are more @ref orxonox::Notification "Notifications" that could be displayed, then only the most recent are displayed.
    159     - @b displayTime The display time specifies how long a @ref orxonox::Notification "Notification" is displayed at the most.
    160 
    161     @subsection NotificationLayer NotificationLayer
    162     The NotificationLayer is a GUI sheet, that displays all the @ref orxonox::NotificationQueue "NotificationQueues" and their @ref orxonox::Notification "Notifications". In its normal mode of operation it is transparent to input, meaning that it only functions as a means of displaying, however if switched to edit mode the NotificationLayer no longer is transparent to input and allows for the adding, removal and modification of @ref orxonox::NotificationQueue "NotificationQueues". For every @ref orxonox::NotificationQueue "NotificationQueue" there is the equivalent representation in the NotificationLayer. So @ref orxonox::NotificationQueue "NotificationQueues" are not each represented by a GUI sheet, but thely all belong to one and the same GUI sheet, the NotificationLayer.
    163 
    164     @subsection NotificationManager NotificationManager
    165     The @ref orxonox::NotificationManager "NotificationManager" is (hence the name) the managing entity in this setting. It is responsible for the registering and unregistering of @ref orxonox::NotificationListener "NotificationListeners" (which the @ref orxonox::NotificationQueue "NotificationQueue" is) and also informs them about changes related to @ref orxonox::Notification "Notifications". It is also responsible for the creation and destruction of @ref orxonox::NotificationQueue "NotificationQueues" through the NotificationLayer and is also the point of approach for the NotificationLayer to get information it needs to display the queues. Finally the @ref orxonox::NotificationManager "NotificationManager" is responsible for sending (and in the process creating) @ref orxonox::Notification "Notifications" and is a means for the @ref orxonox::NotificationQueue "NotificationQueues" to get the information they need about @ref orxonox::Notification "Notifications".
    166 
    167     @subsection Notification Notification
    168     The @ref orxonox::Notification "Notification" class is more or less a data structure that groups the notification message and the sender, and possibly other future parameters, together to form a comprehensive structure that we call Notification.
    169 
    170     Additionally there is another important class of objects belonging to the Notifications module. The @ref orxonox::NotificationDispatcher "NotificationDispatchers".
    171 
    172     @subsection NotificationDispatcher NotificationDispatcher
    173     @ref orxonox::NotificationDispatcher "NotificationDispatchers" are entities that are instantiated in a level file (through XML) and that dispatch (or send) a specific @ref orxonox::Notification "Notification" upon having received a triggering event.
    174 
    175     @defgroup NotificationDispatchers Dispatchers
    176     @ingroup Notifications
    177 
    178     @ref orxonox::NotificationDispatcher "NotificationDispatchers" are entities that are instantiated in a level file (through XML) and that dispatch (or send) a specific @ref orxonox::Notification "Notification" upon having received a triggering event.
    179 
    180     At this point there are two @ref orxonox::NotificationDispatcher "NotificationDispatchers", the @ref orxonox::SimpleNotification "SimpleNotification", which just displays a specified message, and the @ref orxonox::CommandNotification "CommandNotification" which displays a message with a binding for a specified command in it.

    193133    @defgroup Triggers Triggers
    194134    @ingroup Objects
    195 
    196     Triggers are objects which react to certain events. They can be combined and used as simple overlay logic in levels.
    197 
    198     @defgroup NormalTrigger Trigger
    199     @ingroup Triggers
    200 
    201     @defgroup MultiTrigger MultiTrigger
    202     @ingroup Triggers
    203 
    204     @ref orxonox::MultiTrigger "MultiTriggers" are (as they are @ref orxonox::TriggerBase "Triggers") objects which react to certain events. They offer all the functionality that the common @ref orxonox::Trigger "Triggers" do with one significant difference. The common @ref orxonox::Trigger "Trigger" has just one state, it can either be <em>triggered</em> or <em>not triggered</em>, it doesn't discriminate between who's triggering (or not triggering) it. A @ref orxonox::MultiTrigger "MultiTrigger", on the other hand, has a distinct state (<em>triggered</em> or <em>not triggered</em>) for each entity that is defined as being able to trigger said @ref orxonox::MultiTrigger "MultiTrigger".
    205 
    206     This difference becomes significant, when, for example, you want a @ref orxonox::DistanceTrigger "DistanceTrigger" to trigger a @ref orxonox::QuestEffectBeacon "QuestEffectBeacon" to hand out a @ref orxonox::Quest "Quest" to any @ref orxonox::Pawn "Pawn" that enters its range. With a simple @ref orxonox::DistanceTrigger "DistanceTrigger" (as opposed to the more complex @ref orxonox::DistanceMultiTrigger "DistanceMultiTrigger") the first @ref orxonox::Pawn "Pawn" to be in range would trigger it an receive the @ref orxonox::Quest "Quest", however if a second @ref orxonox::Pawn "Pawn" would enter the range, while the first @ref orxonox::Pawn "Pawn" still is in the range nothing would happen and even after the first @ref orxonox::Pawn "Pawn" left nothing would happen, since the whole time the @ref orxonox::DistanceTrigger "DistanceTrigger" would just be triggered. In contrast with a @ref orxonox::DistanceMultiTrigger "DistanceMultiTrigger" the first @ref orxonox::Pawn "Pawn" would enter the range and the @ref orxonox::DistanceMultiTrigger "DistanceMultiTrigger" would have the state <em>triggered</em> for this exact @ref orxonox::Pawn "Pawn" (but for none else) and thus the @ref orxonox::Pawn "Pawn" would receive the @ref orxonox::Quest "Quest" and when the second @ref orxonox::Pawn "Pawn" enters the range the state of the @ref orxonox::DistanceMultiTrigger "DistanceMultiTrigger" for that second @ref orxonox::Pawn "Pawn" would change to <em>triggered</em> and it would receive the @ref orxonox::Quest "Quest" as well.
    207 
    208     @section WhenToUseMultiTriggers When to use MultiTriggers
    209     Consequentially you would use @ref orxonox::MultiTrigger "MultiTriggers" (instead of common @ref orxonox::Trigger "Triggers"), when it is important that the trigger has different states for each triggering entity and when that fact is essential in the concept of the object that reacts to the triggering. However you should not just use @ref orxonox::MultiTrigger "MultiTrigger" instead of @ref orxonox::Trigger "Trigger", when in doubt, because @ref orxonox::MultiTrigger "MultiTrigger" produces significantly more overhead than @ref orxonox::Trigger "Trigger" due to the added complexity.
    210 
    211     @section HowToUseMultiTriggers How to use MultiTriggers
    212     ...
    213 
    214     @section MultiTriggerTechnicalDetails Technical Details
    215     A common @ref orxonox::Trigger "Trigger" is an object that can either be <em>active</em> or <em>inactive</em>, with a specified behavior how to switch between the two. A @ref orxonox::MultiTrigger "MultiTrigger" generalizes that behavior for multiple objects triggering the trigger. A @ref orxonox::MultiTrigger "MultiTrigger" can be <em>active</em> or <em>inactive</em> for any object triggering it, with the state for each object being completely independent of the state for all other objects. Each time a switch occurs an @ref orxonox::Event "Event" is fired, with a @ref orxonox::MultiTriggerContainer "MultiTriggerContainer" as the originator, containing a pointer to the @ref orxonox::MultiTrigger "MultiTrigger" that caused the @ref orxonox::Event "Event" and a pointer to the object that caused the trigger to change it's activity. This way the entity that reacts to the @ref orxonox::MultiTrigger "MultiTrigger" triggering receives the information it needs about the entity that triggered the @ref orxonox::MultiTrigger "MultiTrigger".
    216 
    217     Also, just as with all triggers, @ref orxonox::MultiTrigger "MultiTriggers" can be nested (event with triggers other than @ref orxonox::MultiTrigger "MultiTriggers").
    218     @code
    219     <MultiTrigger switch="true" delay="2">
    220         <DistanceMultiTrigger position="100,0,0" distance="80" />
    221         <EventTrigger ... />
    222     </Trigger>
    223     @endcode
    224 
    225     @ref orxonox::MultiTrigger "MultiTriggers" also allow for additional complexity which can be added through the choice of the parameters (some of which are also present in the common @ref orxonox::Trigger "Trigger") explained (briefly) below.
    226     But first it is important to understand a small implementational detail. There is a distinction between the @ref orxonox::MultiTrigger "MultiTrigger" being triggered (there is the state <em>triggered</em> for that) and the @ref orxonox::MultiTrigger "MultiTrigger" being active (for that is the state <em>activity</em>). From the outside only the <em>activity</em> is visible (and has above been referred to as <em>triggered</em> for the sake of comprehensibility). The state <em>triggered</em> tells us whether the trigger is actually triggered, but it could pretend (for some reason, some of which we will see shortly) to be <em>triggered</em> to the outside, while it in fact isn't (but it would then be <em>active</em>). The standard behavior is, that the <em>activity</em> changes, when the @ref orxonox::MultiTrigger "MultiTrigger" transits from being triggered to not being triggered or the other way around. So to the inside a @ref orxonox::MultiTrigger "MultiTrigger" being <em>active</em> is synonymous to the @ref orxonox::MultiTrigger "MultiTrigger" being <em>triggered</em> to the outside.
    227 
    228     The parameters of the @ref orxonox::MultiTrigger "MultiTrigger" are:
    229     - @b delay The delay is the time in seconds, that the trigger waits until it reacts (i.e. changes it's state) to the triggering condition being fulfilled. Internally this is handled by a state queue coupled with a counter, for each state that is delayed. The state becomes <em>active</em> when the counter runs out. This allows the @ref orxonox::MultiTrigger "MultiTrigger" to work even if the delay changes at runtime. However if the delay changes it only affects newly arriving states not the ones already in the queue. The default is <code>0</code>.
    230     - @b switch Switch is a boolean, if <code>true</code> the @ref orxonox::MultiTrigger "MultiTrigger" is in <em>switch-mode</em>, meaning, that the <em>activity</em> changes only when the trigger is triggered, not when it is un-triggered (Just like a light switch does). This means, that in <em>switch-mode</em> the <em>activity</em> only changes, when the trigger changes from not being triggered to being triggered but not the other way around. The default is <code>false</code>.
    231     - @b stayActive Stay active is also a boolean, if <code>true</code> the @ref orxonox::MultiTrigger "MultiTrigger" stays active after it has been activated as many times as specified by the parameter <em>activations</em>. In essence this means, that after the last time it is activated it cannot be deactivated. The default is <code>false</code>.
    232     - @b activations Activations is the number of times the @ref orxonox::MultiTrigger "MultiTrigger" can be activated until the trigger can't be triggered anymore. The default is <code>-1</code>, which denotes infinity.
    233     - @b invert Invert is a boolean, if <code>true</code> the @ref orxonox::MultiTrigger "MultiTrigger" is in <em>invert-mode</em>, meaning, that if the triggering condition is fulfilled the @ref orxonox::MultiTrigger "MultiTrigger" will have the state <em>not triggered</em> and and if the condition is not fulfilled it will have the state <em>triggered</em>. In short it inverts the behavior of the @ref orxonox::MultiTrigger "MultiTrigger". The default is <code>false</code>.
    234     - @b simultaneousTriggerers The number of simultaneous triggerers limits the number of objects that are allowed to trigger the @ref orxonox::MultiTrigger "MultiTrigger" at the same time. Or more precisely, the number of distinct objects the @ref orxonox::MultiTrigger "MultiTrigger" has positive <em>triggered</em> states for, at each point in time. The default is <code>-1</code>, which denotes infinity.
    235     - @b mode The mode describes how the @ref orxonox::MultiTrigger "MultiTrigger" acts in relation to all the triggers (its children), that are appended to it. There are 3 modes: <em>and</em>, meaning that the @ref orxonox::MultiTrigger "MultiTrigger" can only be triggered if all the appended triggers are active. <em>or</em>, meaning that the @ref orxonox::MultiTrigger "MultiTrigger" can only be triggered if at least one of the appended triggers is active. And <em>xor</em>, meaning that the @ref orxonox::MultiTrigger "MultiTrigger" can only be triggered if one and only one appended trigger is active. Note, that I wrote 'can only be active', that implies, that there is an additional condition to the <em>activity</em> of the @ref orxonox::MultiTrigger "MultiTrigger" and that is the fulfillment of the triggering condition (the @ref orxonox::MultiTrigger "MultiTrigger" class itself doesn't have one, but all derived classes should). Also bear in mind, that the <em>activity</em> of a @ref orxonox::MultiTrigger "MultiTrigger" is still coupled to the object that triggered it. The default is <em>and</em>.
    236     - @b broadcast Broadcast is a boolean, if <code>true</code> the @ref orxonox::MultiTrigger "MultiTrigger" is in <em>broadcast-mode</em>, meaning, that all trigger events that are caused by no originator (originator is <code>NULL</code>) are broadcast as having come from every possible originator, or more precisely as having come from all objects that are specified targets of this @ref orxonox::MultiTrigger "MultiTrigger". The default is <code>false</code>.
    237     - @b target The target describes the kind of objects that are allowed to trigger this @ref orxonox::MultiTrigger "MultiTrigger". The parameter has to be set to the class name of the class that is allowed to trigger the @ref orxonox::MultiTrigger "MultiTrigger". The default is <code>Pawn</code>.
    238 
    239     @subsection Sub-typesOfMultiTriggers Sub-types of MultiTriggers
    240 
    241     @subsubsection EventMultiTrigger EventMultiTrigger
    242     An @ref orxonox::EventMultiTrigger "EventMultiTrigger" can either be used to broadcast an @ref orxonox::Event "Event" that does not come from a @ref orxonox::MultiTrigger "MultiTrigger" to all entities that are targets of the @ref orxonox::EventMultiTrigger "EventMultiTrigger" or, more in line with its prototype the @ref orxonox::EventTrigger "EventTrigger", to be triggered for an entity when an @ref orxonox::Event "Event" that was caused by an entity of the same type is captured.
    243 
    244     A common usage could look like this:
    245     @code
    246     <EventMultiTrigger invert="true" delay="1">
    247         <events>
    248             <trigger>
    249                 <MultiTrigger ... />
    250                 <Trigger ... />
    251             </trigger>
    252         </events>
    253     </EventMultiTrigger>
    254     @endcode
    255 
    256     @subsubsection DistanceMultiTrigger DistanceMultiTrigger
    257     A @ref orxonox::DistanceMultiTrigger "DistanceMultiTrigger" is the MultiTrigger equivalent of the @ref orxonox::DistanceTrigger "DistanceTrigger" and works just the same way. It triggers (now separately for each object triggering it, since it's a @ref orxonox::MultiTrigger "MultiTrigger") whenever an object that is a target of the @ref orxonox::DistanceMultiTrigger "DistanceMultiTrigger" is in the specified range.
    258 
    259     Two additional parameters can be specified for the @ref orxonox::DistanceMultiTrigger "DistanceMultiTrigger" are the <em>distance</em>, which defines the maximum distance at which an object still triggers the @ref orxonox:: "DistanceMultiTrigger", and the <em>targetname</em>. Setting the <em>targename</em> puts the @ref orxonox::DistanceMultiTrigger "DistanceMultiTrigger" in <em>single-target mode</em>. In this mode the @ref orxonox::DistanceMultiTrigger "DistanceMultiTrigger"  can only be triggered by objects that have a @ref orxonox::DistanceTriggerBeacon "DistanceTriggerBeacon" with the name specified by <em>targetname</em> directly attached. For the <em>single-target mode</em> to work the target of the @ref orxonox::DistanceMultiTrigger "DistanceMultiTrigger" has to be set to <code>DistanceTriggerBeacon</code>.
    260 
    261     A common usage (without @ref orxonox::DistanceTriggerBeacon "DistanceTriggerBeacon") would look like this:
    262     @code
    263     <DistanceMultiTrigger position="0,0,0" switch="true" target="Pawn" distance="20" />
    264     @endcode
    265 
    266     With @ref orxonox::DistanceTriggerBeacon "DistanceTriggerBeacon" it would look like this:
    267     @code
    268     <DistanceMultiTrigger position="0,0,0" target="DistanceMultiTrigger" targetname="beacon1" distance="30" />
    269     @endcode

    279144    @ingroup Modules
    280 
    281     The Pickup module adds a special type of object to Orxonox, the so-called @ref orxonox::Pickupable "Pickupables". @ref orxonox::Pickupable "Pickupables" are objects that can be picked up (by virtually any entity, but commonly by the @ref orxonox::Pawn "Pawn") and have some kind of effect on the entity that picked the @ref orxonox::Pickupable "Pickupable" up.
    282 
    283     @section IncludingPickups Including pickups in a level
    284     @ref orxonox::Pickupable "Pickupables" are designed so that they can be included in levels fairly easily, while also ensuring, that the pickup itself (its game-logic component) and how it is represented (e.g. in the PickupInventory (the GUI that displays @ref orxonox::Pickupable "Pickupables") or in the game) are neatly seperated.
    285     To be able to use @ref orxonox::Pickupable "Pickupables" in a level one must understand some basic concepts.
    286     - @ref orxonox::Pickupable "Pickupables" are entities which (by itself) have no physical (or graphical) dimension. The simply represent the effect they will have on a @ref orxonox::PickupCarrier "PickupCarrier" (the entity that can pick up @ref orxonox::Pickupable "Pickupables", @ref orxonox::Pawn "Pawn" for example inherits from @ref orxonox::PickupSpawner "PickupSpawner" and thus is able to pick up and carry @ref orxonox::Pickupable "Pickupables"), when used and the mechanism that leads to that.
    287     - The physical (or graphical) dimension of a pickup is called a @ref orxonox::PickupRepresentation "PickupRepresentation".
    288     - The @ref orxonox::PickupRepresentation "PickupRepresentation" of a @ref orxonox::Pickupable "Pickupable" and the @ref orxonox::Pickupable "Pickupable" itself are linked to each other, in such a way that a @ref orxonox::PickupRepresentation "PickupRepresentation" can only represent one type of @ref orxonox::Pickupable "Pickupable".
    289     - A type of @ref orxonox::Pickupable "Pickupable" is a specific pickup class (inheriting from @ref orxonox::Pickupable "Pickupable") with specific values for all its relevant parameters. This means, that a pickup of the same class with the same values for all parameters except for one is a different type of pickup and will therefore have a different @ref orxonox::PickupRepresentation "PickupRepresentation". Which parameters are the ones relevant to destinguish between two types of pickups can be defined in the class description of the specific pickup.
    290     - The entity that actually gives a @ref orxonox::Pickupable "Pickupable" to a @ref orxonox::PickupCarrier "PickupCarrier" is called a @ref orxonox::PickupSpawner "PickupSpawner". A @ref orxonox::PickupSpawner "PickupSpawner" creates (based on some parameters) @ref orxonox::Pickupable "Pickupables" which then is picked up by the @ref orxonox::PickupCarrier "PickupCarrier", that caused the @ref orxonox::PickupSpawner "PickupSpawner" to spawn a new pickup. How the spawner looks in the game is defined by the @ref orxonox::PickupRepresentation "PickupRepresentation" of the @ref orxonox::Pickupable "Pickupable" it spawns.
    291 
    292     @subsection UsingPredifinedPickups Using predefined pickups
    293     There is a file called <code>pickupRepresentationTemplates.oxt</code> in <code>levels/templates</code>, which holds the templates for the @ref orxonox::PickupRepresentation "PickupRepresentations" and also templates for @ref orxonox::Pickupable "Pickupables". The templates for the @ref orxonox::PickupRepresentation "PickupRepresentations" define the @ref orxonox::StaticEntity "StaticEntities" that are attached to the @ref orxonox::PickupSpawner "PickupSpawners" to make them look like the @ref orxonox::Pickupable "Pickupable" they are spawning. The templates for the @ref orxonox::Pickupable "Pickupables" can be added just for ease of use.
    294     If you want to use pickups you will have to include this file in your level file, somewhere above the Level-tag.
    295     @code
    296     <?lua
    297         include("templates/pickupRepresentationTemplates.oxt")
    298     ?>
    299     ...
    300     <Level>
    301     ...
    302     @endcode
    303     There is another file called <code>pickups.oxi</code> in <code>level/includes</code> which creates all @ref orxonox::PickupRepresentation "PickupRepresentations" needed for the @ref orxonox::Pickupable "Pickupable" supplied by the <code>pickupRepresentationTemplates.oxt</code> file. This file will have to be included as well. It has to be somewhere after the opening Scene-tag and your first use of a pickup.

    308         include("includes/pickups.oxi")
    309     ?>
    310     @endcode
    311     After that all the predefined pickups specified in those two files can be used just by creating a @ref orxonox::PickupSpawner "PickupSpawner" for them in the respective level.
    312     For example:
    313     @code
    314     <PickupSpawner position="-100,0,-100" respawnTime="30" maxSpawnedItems="10">
    315         <pickup>
    316             <HealthPickup
    317                 health = 10
    318                 healthType = "limited"
    319                 activationType = "immediate"
    320                 durationType = "once"
    321             />
    322         </pickup>
    323     </PickupSpawner>
    324     @endcode
    325     Please be aware, that the @ref orxonox::Pickupable "Pickupable" specified for the @ref orxonox::PickupSpawner "PickupSpawner", has to be exactly the same (including all parameters) to the one specified in the <code>pickups.oxi</code> file.
    326     To make things simpler, one could just use the templates specified in the <code>pickupRepresentationTemplates.oxt</code> file. Which, following the previous example, would look like this:
    327     @code
    328     <PickupSpawner position="-100,0,-100" respawnTime="30" maxSpawnedItems="10">
    329         <pickup>
    330             <HealthPickup template="smallhealthpickup" />
    331         </pickup>
    332     </PickupSpawner>
    333     @endcode
    334 
    335     @subsection UnsingNon-PredefinedPickups Using non-predefined pickups
    336     To include a type of pickup (which, as we remember, is the class of the @ref orxonox::Pickupable "Pickupable" with specific values for all the relevant parameters) in a level file, you can just create a new @ref orxonox::PickupSpawner "PickupSpawner" and specify the @ref orxonox::Pickupable "Pickupable".
    337     @code
    338     <PickupSpawner position="-100,0,-100" respawnTime="30" maxSpawnedItems="10">
    339     <pickup>
    340         <HealthPickup
    341             health = 33
    342             healthType = "limited"
    343             activationType = "immediate"
    344             durationType = "once"
    345         />
    346     </pickup>
    347     </PickupSpawner>
    348     @endcode
    349     As can be seen in the <code>pickupRepresentationTemplates.oxt</code> file and the <code>pickups.oxi</code> file there is no @ref orxonox::PickupRepresentation "PickupRepresentation" defined for this type of pickup. Thus the default representation will be used.
    350 
    351     To create an appropriate @ref orxonox::PickupRepresentation "PickupRepresentation" for the inserted pickup above, you can just create a @ref orxonox::PickupRepresentation "PickupRepresentation" within the scene (Within the Scene-tags).
    352     @code
    353     <PickupRepresentation
    354         name = "My new health pickup"
    355         description = "This is an awesome new health pickup."
    356         spawnerTemplate = "mediumhealthpickupRepresentation"
    357         inventoryRepresentation = "MediumHealth"
    358     >
    359         <pickup>
    360             <HealthPickup
    361             health = 33
    362             healthType = "limited"
    363             activationType = "immediate"
    364             durationType = "once"
    365         />
    366         </pickup>
    367     </PickupRepresentation>
    368     @endcode
    369     Notice, that the type of pickup specified for the @ref orxonox::PickupRepresentation "PickupRepresentation", naturally, needs to be the same (this is the way they can be connected). Also, we just used an existing <em>spawnerTemplate</em>, to make things simpler.
    370 
    371     The next step is to create a <em>spawnerRepresentation</em> uniquely for our new type of pickup. Lets call it <code>newhealthpickupRepresentation</code>. Thus the parameter <em>spawnerTemplate</em> of the @ref orxonox::PickupRepresentation "PickupRepresentation" has to be changed to that value.
    372     @code
    373     spawnerTemplate = "newhealthpickupRepresentation"
    374     @endcode
    375     The <em>spawnerTemplate</em> defines how the @ref orxonox::PickupSpawner "PickupSpawner" is displayed in a level.
    376     In our example case it could look like this:
    377     @code
    378     <Template name=newhealthpickupRepresentation>
    379         <PickupRepresentation>
    380             <spawner-representation>
    381                 <StaticEntity>
    382                     <attached>
    383                         -- Here you can put all the objects which define the look of the spawner. --
    384                     </attached>
    385                 </StaticEntity>
    386             </spawner-representation>
    387         </PickupRepresentation>
    388     </Template>
    389     @endcode
    390     Please refer to the <code>pickupRepresentationTemplates.oxt</code> for more examples.
    391 
    392     The @ref orxonox::PickupRepresentation "PickupRepresentation" also needs another parameter the <em>inventoryRepresentation</em>. This parameter defined how the @ref orxonox::Pickupable "Pickupable" is displayed in the PickupInventory (a menu to browse the currently equipped pickups).
    393     @code
    394     inventoryRepresentation = "MediumHealth"
    395     @endcode
    396     This is the name of an image defined in the PickupInventory imageset (<code>PickupInventory.imageset</code>), which can be found in <code>data_extern/gui/imagesets</code>.
    397 
    398     This is all that has to be done. Now you have a new pickup type with an appropriate @ref orxonox::PickupRepresentation "PickupRepresentation" for your use. If you feel that your pickup is useful in general, please don't hesitate to create a template for the pickup and add your pickup to the <code>pickupRepresentationTemplates.oxt</code> file and the <code>pickups.oxi</code> file, so that anyone who wants to use it can do so quite easily.
    399 
    400     There is also an additional way to create new types of pickups to be used in a level (without having to do any coding). There is a @ref orxonox::Pickupable "Pickupable" called the @ref orxonox::PickupCollection "PickupCollection", which is just a collection (hence the name) of @ref orxonox::Pickupable "Pickupables" (more precisely of @ref orxonox::CollectiblePickup "CollectiblePickups"), behaving as if it was just one @ref orxonox::Pickupable "Pickupable".
    401     A @ref orxonox::PickupCollection "PickupCollection" can be created as follows:
    402     @code
    403     <PickupCollection>
    404         <pickupables>
    405             -- some pickups you want to have in your collection, e.g. --
    406             <HealthPickup template=smallhealthpickup />
    407             <HealthPickup health=50 healthRate=5 durationType=continuous activationType=immediate healthType=limited />
    408         </pickupables>
    409     </PickupCollection>
    410     @endcode
    411     Of which types of pickups a collection is made up is entirely up to the one creating the @ref orxonox::PickupCollection "PickupCollection", they can be mixed freely.
    412 
    413     @section CreatingAPickup Creating a new pickup
    414     Things have been fairly straightforward so far. Creating a @ref orxonox::Pickupable "Pickupable" form scratch isn't as easy. Therefore I'm just going to supply you with a recipe, or a set of steps you have to take, without which your pickup won't work and point out some common pitfalls.
    415 
    416     @subsection CreatingAPickupClass Creating the class
    417     For a new @ref orxonox::Pickupable "Pickupable" you need to create a new class in <code>>modules/pickup/items</code>. Your class needs to be derived from another pickup class, normally this would either be @ref orxonox::Pickupable "Pickupable", @ref orxonox::CollectiblePickup "CollectiblePickup" or @ref orxonox::Pickup "Pickup". @ref orxonox::Pickupable "Pickupable" is (as mentioned earlier) the base class of all things that can be picked up, thus of all pickups. @ref orxonox::CollectiblePickup "CollectiblePickup" is a (directly) derived class of @ref orxonox::Pickupable  "Pickupable" and provides the additional functionality of enabling your pickup to be used in a @ref orxonox::PickupCollection "PickupCollection". However you are probably going to want to derive your class form @ref orxonox::Pickup "Pickup", because it is a @ref orxonox::CollectiblePickup "CollectiblePickup" and provides some useful methods. So have a look at @ref orxonox::Pickup "Pickup".
    418     Once you have created your new pickup class you have to insert it in the <code>PickupPrereqs.h</code> file in the <code>modules/pickup</code> folder and in the <code>CMakeList.txt</code> file in the <code>modules/pickup/items</code> folder. Also have a look at other pickups to make sure you include all the necessary files in your class.
    419 
    420     @subsection ChoosingTheCarriers Coosing the carriers
    421     You also have to choose the entities that are allowed to pick your pickup up. After you have chosen the entity that carries your pickup, you need to do the following.
    422     - The enity that carries your pickup needs to be derived from the @ref orxonox::PickupCarrier "PickupCarrier" interface. And you need to implement the @ref orxonox::PickupCarrier "PickupCarriers'" virtual functions <code>getCarrierChildren()</code> and <code>getCarrierParent()</code>. These tow methods are needed, because all pickups are initially picked up by a @ref orxonox::Pawn "Pawn" and then handed down to the entity that effectively carries them. With the above mentioned two function just that is accomplished. A hierarchical structure is established with one parent and a set of children, where the @ref orxonox::Pawn "Pawn" is the root node of this hierarchical structure, the only entity with no parent.
    423     - Once you have done that you will also want to specify in your pickup which carriers can pick it up, this is done via the <code>addTarget()</code> function. So you have to make sure the target is added whenever one of your pickups is created (so, most conveniently somewhere in the constructor), with the following command.
    424     @code
    425     this->addTarget(ClassIdentifier<MyCarrierClass>::getIdentifier());
    426     @endcode
    427 
    428     @subsection CreatingTheInnerWorkings Creating the inner workings of your pickup
    429     Now that we have the skeleton of a pickup and we have defined which carriers are allowed to pick our pickup up we are going to take a look at all the methods we can (or sometimes have to) overload from @ref orxonox::Pickupable "Pickupable", for our pickup to work properly. But first I will introduce some more concepts to make the need for these methods more obvious.
    430     - Since one pickup class can by itself be many pickup types, we need a way to find out whether a particular instance of a pickup is of the same type as another instance of a pickup. To that end the @ref orxonox::PickupIdentifier "PickupIdentifier" was created. The @ref orxonox::PickupIdentifier "PickupIdentifier" accounts for the type of class your pickup is of and also for the parameters (and their values) that distinguish different types of pickups of the same class. Much of the functionality of the pickup module relies on this identifier being correct, thus it is very important to initialize it correctly. (We will see, how that is done in a short while.)
    431     - Every @ref orxonox::Pickupable "Pickupable" has at least two states which are very important. The first is, whether the @ref orxonox::Pickupable "Pickupable" is currently in use or not and the second is whether the pickup is currently picked up or not.
    432 
    433     Let's have a look at the important methods.
    434     - <b>changedUsed()</b> The <code>changedUsed()</code> method is called whenever the state of the @ref orxonox::Pickupable "Pickupable" transits from being used to not being used or the other way around. Which means this method is probably the most important method you have at your fingertips, since it enables you to apply the effect of your pickup when it gets used and remove the effect as soon as it is no longer in use.
    435     - <b>changedPickedUp()</b> The <code>changedPickedUp()</code> method is called whenever the state of the @ref orxonox::Pickupable "Pickupable" changes from being picked up to not being picked up or the other way around. For example if you want your pickup to be used as soon as it is picked up, this is the method you have to overload to achieve that behavior (or just let your pickup be derived from @ref orxonox::Pickup "Pickup", which implements exactly that behavior, if the <em>activationType</em> is set to <em>immediate</em>). You don't have to concern yourself with destroying the pickup or creating a spawner when it changes to not picked up, since that is already implemented with the @ref orxonox::Pickupable "Pickupable" and @ref orxonox::PickupCarrier "PickupCarrier" classes. If you want a different behavior, however, once again, this is the method.
    436     - <b>changedCarrier()</b> The <code>changedCarrier()</code> method is called whenever the carrier of the @ref orxonox::Pickupable "Pickupable" changes. And by that I don't mean the class that is allowed to carry the pickup, but the object that actually carries (or carried) the pickup. Please do not overload this class to implement behavior for picked up -> not picked up transitions, use <code>changedPickedUp()</code> for that. For most pickup classes this method doesn't need to be overloaded. Where it is used, however is in the @ref orxonox::PickupCollection "PickupCollection" class, where the new carrier needed to be communicated to all pickups the collection consists of, whenever the carrier was changed.
    437 
    438     Please be aware, that these three methods are methods registered with @ref Super.h "Super", meaning, that whenever overloading them, don't forget to call <code>SUPER(MyClass, myMethod);</code>.
    439     Also when implementing the above methods you should think of what should happen in unexpected situations, e.g. when your pickup is unused manually and set to used again.
    440     Additionally you should use the <code>destroy()</code> method of Pickupable instead of the method provided by @ref orxonox::OrxonoxClass "OrxonoxClass", meaning <code>Pickupable::destroy()</code> instead of plain <code>destroy()</code>.
    441 
    442     - <b>clone()</b> The <code>clone()</code> method creates a new pickup of the same type as the pickup it is cloned from. So the cloned pickup is not exactly the same, as it doesn't necessarily completely reflect the status of the pickup it is cloned from, but it reflects all the parameters and their values, that distinguish different types of this pickup class. It needs to be implemented by every pickup class. And it is best if this is done in a very specific way. Below is shown how:
    443     @code
    444     void MyPickup::clone(OrxonoxClass*& item)
    445     {
    446         if(item == NULL)
    447             item = new MyPickup(this);
    448 
    449         SUPER(MyPickup, clone, item);
    450 
    451         MyPickup* pickup = dynamic_cast<MyPickup*>(item);
    452         // Here you should set all the important parameters (that distinguish the different types of this pickup), e.g.
    453         pickup->setSomeParameter(this->getSomeParameter());
    454         // You must also initialize the identifier of the new pickup, this is normally done in a member function called in
    455         pickup->initializeIdentifier();
    456     }
    457     @endcode
    458     - <b>initializeIdentifier()</b> The <code>initializeIdentifier()</code> method initializes (or more simply put, creates) the @ref orxonox::PickupIdentifier "PickupIdentifier" of the instance of your pickup. Since the important values of the parameters are not yet available in the constructor of your pickup this <code>initializeIdentifier()</code> method must be called as soon as they are available, which normally is in the <code>XMLPort()</code> method, and the <code>clone()</code> method, as seen above. In the <code>initializeIdentifier()</code> method you need to register each parameter that is important for the type of your pickup to its identifier, this is normally done as follows:
    459     @code
    460     void Pickup::initializeIdentifier(void)
    461     {
    462         // If the get method returns a string.
    463         std::string val1 = this->getSomeParameter();
    464         std::string type1 = "someParameter";
    465         this->pickupIdentifier_->addParameter(type1, val1);
    466         // If the get method doesn't return a string
    467         std::stringstream stream;
    468         stream << this->getSomeOtherParameter();
    469         std::string type2 = "someOtherParameter";
    470         std::string val2 = stream.str();
    471         this->pickupIdentifier_->addParameter(type2, val2);
    472     }
    473     @endcode
    474 
    475     Be aware, this only works for parameters that are simple enough, meaning with pointers for example it will, naturally, not work, and other ways must be found (this is for example done in @ref orxonox::PickupCollection "PickupCollection" with a derived class of the @ref orxonox::PickupIdentifier "PickupIdentifier", the @ref orxonox::PickupCollectionIdentifier "PickupCollectionIdentifier") or in the @ref orxonox::DronePickup "DronePickup" class by using a @ref orxonox::Template "Template".
    476     - <b>createSpawner()</b> The <code>createSpawner()</code> method needs to be implemented by any pickup directly inheriting from @ref orxonox::Pickupable "Pickupable" (or directly from @ref orxonox::CollectiblePickup "CollectiblePickup"), so if you inherit from @ref orxonox::Pickup "Pickup", you don't need to implement this. It is used to create a @ref orxonox::PickupSpawner "PickupSpawner", when the pickup is dropped. A standard implementation would look like this.
    477     @code
    478     bool MyPickup::createSpawner(void)
    479     {
    480         new DroppedPickup(this, this, this->getCarrier());
    481         return true;
    482     }
    483     @endcode

    507 
    508     The Questsystem is a module that enhances Orxonox with @ref orxonox::Quest "Quests". @ref orxonox::Quest "Quests" are objects that challenge the player that receives such an object to fulfill some specific task (e.g. Rescue a princess, fetch some rare metal alloy, destroy the evil pirates den, ...). Upon having fulfilled that task the player can be rewarded with some kind of reward. Quests can be hierarchically structured, meaning that to fulfill some @ref orxonox::Quest "Quest" you first have to fulfill all (or some, depending on the quest) sub-quests.
    509 
    510     @section QuestsystemTechnicalDetails Technical details
    511     The Questsystem essentially consists of the @ref orxonox::Quest "Quest" entity which is the quest itself (and sub- or helper-entities, such as @ref orxonox::QuestHint "QuestHint" (hints for quests) or @ref orxonox::QuestDescription "QuestDescription" (descriptions for quests and hints, to separate content from function)), the @ref orxonox::QuestEffect "QuestEffect" and @ref orxonox::QuestListener "QuestListener" entities which are the only tools for quests to have any influence on the game world. By enabling quests to have @ref orxonox::QuestEffect "QuestEffects" they are able to (for example) fail or complete other quests, activate hints, give rewards or even add a quest to a player. @ref orxonox::QuestListener "QuestListeners" on the other hand can be used by any object to react to a status change of a quest. The @ref orxonox::QuestEffectBeacon "QuestEffectBeacon" is the physical entity which finally makes quests available for the player in the game, by being able to invoke a @ref orxonox::QuestEffect "QuestEffect" on a player (under some conditions).

    514     @section CreatingQuests Creating Quests
    515 
    516     @subsection CreatingTheQuestHierarchy Creating the Quest-Hierarchy
    517     To start you have to create a Quest-Hierarchy in the XML-Levelfile by hierarchically nesting your quests. There are two types of Quests you can use, the LocalQuest and the GlobalQuest.
    518 
    519     @subsubsection LocalQuest LocalQuest
    520     A @ref orxonox::LocalQuest "LocalQuest" is a @ref orxonox::Quest "Quest" which has different states for each player, that means each @ref orxonox::LocalQuest "LocalQuest" can be obtained and completed (or failed) by each player in parallel. A questId is some string that uniquely identifies the quest, this can either be a name or, to ensure uniqueness, you can use a GUID generator (<a href="http://www.google.com/search?q=guid+generator">google</a> or you can use this <a href="http://www.famkruithof.net/uuid/uuidgen">generator</a>). The advantage of GUID is, that you can be quite sure that your id is unique, the drawback is, that it provides less overview and can be quite confusing when looking at the level file. So make your own choice.
    521 
    522     Creating a @ref orxonox::LocalQuest "LocalQuest" in XML goes as follows:
    523     @code
    524     <LocalQuest id="questId">
    525         <QuestDescription title="Title" description="Description." /> //The description of the quest.
    526         <subquests>
    527             <Quest id ="questId1" /> //A list of n subquest, be aware, each of the <Quest /> tags must have a description and so on and so forth as well.
    528             ...
    529             <Quest id="questIdn" />
    530         </subquests>
    531         <hints>
    532             <QuestHint id="hintId1" /> //A list of n QuestHints, see QuestHint for the full XML representation of those.
    533             ...
    534             <QuestHint id="hintIdn" />
    535         </hints>
    536         <fail-effects>
    537             <QuestEffect /> //A list of QuestEffects, invoked when the Quest is failed, see QuestEffect for the full XML representation.
    538             ...
    539             <QuestEffect />
    540         </fail-effects>
    541         <complete-effects>
    542             <QuestEffect /> //A list of QuestEffects, invoked when the Quest is completed, see QuestEffect for the full XML representation.
    543             ...
    544             <QuestEffect />
    545         </complete-effects>
    546     </LocalQuest>
    547     @endcode
    548 
    549     @subsubsection GlobalQuest GlobalQuest
    550     @ref orxonox::GlobalQuest "GlobalQuests" are different, they can be obtained by every player but the changes made to the @ref orxonox::Quest "Quest" (e.g. completion of the quest) affect all owners of the quest. A short example: There are 3 Players, A, B and C. Player A obtains the quest, a while later player B obtains the quest and completes it. Since it is a @ref orxonox::GlobalQuest "GlobalQuest" it is completed for all players having obtained the Quest which means it is also completed for player A. Player C though, never having obtained the quest, can now never complete it.
    551 
    552     Creating a @ref orxonox::GlobalQuest "GlobalQuest" in XML goes as follows:
    553     @code
    554     <GlobalQuest id="questId">
    555         <QuestDescription title="Title" description="Description." /> //The description of the quest.
    556         <subquests>
    557             <Quest id ="questId1" /> //A list of n subquest, be aware, each of the <Quest /> tags must have a description and so on and so forth as well.
    558             ...
    559             <Quest id="questIdn" />
    560         </subquests>
    561         <hints>
    562             <QuestHint id="hintId1" /> //A list of n QuestHints, see QuestHint for the full XML representation of those.
    563             ...

    583 
    584     As you may see that another difference between a @ref orxonox::GlobalQuest "GlobalQuest" and a @ref orxonox::LocalQuest "LocalQuest" is, that with a @ref orxonox::GlobalQuest "GlobalQuest" having @ref orxonox::AddReward "RewardEffects", the RewardEffects are only executed on the player completing the quest. Additionally @ref orxonox::CompleteQuest "CompleteEffects" are executed on all players having obtained the quest before it was completed, when it is completed., while with a @ref orxonox::LocalQuest "LocalQuest" each player that completes a quest, completes it for himself alone, but also gets the reward, regardless whether another player completed the quest before him.
    585 
    586     @subsubsection QuestHint QuestHint
    587     @ref orxonox::QuestHint "QuestHints" can be used to give a player useful information for @ref orxonox::Quest "Quests" he is working on completing. @ref orxonox::QuestHint "QuestHints" cannot have any side effects, but also have an identifier which follows the same form as in the @ref orxonox::Quest "Quests".
    588 
    589     Creating a @ref orxonox::QuestHint "QuestHint" in XML goes as follows:
    590     @code
    591     <QuestHint id="hintId">
    592         <QuestDesctription title="" description="" />
    593     </QuestHint>
    594     @endcode
    595 
    596     @subsubsection QuestDescription QuestDescription
    597     Each @ref orxonox::Quest "Quest" (and also each @ref orxonox::QuestHint "QuestHint") must have a @ref orxonox::QuestDescription "QuestDescription" consisting of a title and description, and for @ref orxonox::Quest "Quests" also messages for the event the quest is either failed or completed. Of course these are (as is the title and the description) optional.
    598 
    599     Creating a @ref orxonox::QuestDescription "QuestDescription" in XML goes as follows:
    600     @code
    601     <QuestDescription title="Title" description="Description Text" failMessage="You fail." completeMessage="You win!" />
    602     @endcode
    603 
    604     @subsection CreatingSideEffects Creating side effects
    605     @ref orxonox::Quest "Quests" can have side effects, in fact that is mostly what they are about. This means that they can have an influence on the game world. @ref orxonox::Quest "Quests" do that through two distinct devices, @ref orxonox::QuestEffect "QuestEffects" (active) and @ref orxonox::QuestListener "QuestListeners" (passive).
    606 
    607     @subsubsection QuestEffect QuestEffect
    608     A @ref orxonox::QuestEffect "QuestEffect" is the first (and probably most important) device for @ref orxonox::Quest "Quests" to have side effects. There are two entities that can have @ref orxonox::QuestEffect "QuestEffects": @ref orxonox::Quest "Quests" and @ref orxonox::QuestEffectBeacon "QuestEffectBeacons" (which will be explained later on). @ref orxonox::QuestEffect "QuestEffects", for example, can start a @ref orxonox::Quest "Quest" for a player, complete/fail @ref orxonox::Quest "Quests" for a player, add a @ref orxonox::QuestHint "QuestHint" or a @ref orxonox::Rewardable "Reward" to a player, and potentially much, much more.
    609 
    610     These @ref orxonox::QuestEffect "QuestEffects" are implemented so far, but feel free to <a href="http://www.orxonox.net/wiki/DamianFrick">contact me</a> if you have suggestions for new @ref orxonox::QuestEffect "QuestEffects" or if you need help implementing a new one yourself.
    611 
    612     @paragraph AddQuest AddQuest
    613     This @ref orxonox::QuestEffect "QuestEffect" adds (respectively starts) a @ref orxonox::Quest "Quest" (identified by the given questId) to the player.
    614     @code
    615     <AddQuest questId="id" />  //Where id identifies the Quest that should be added.
    616     @endcode
    617 
    618     @paragraph FailQuest FailQuest
    619     This @ref orxonox::QuestEffect "QuestEffect" fails a @ref orxonox::Quest "Quest" (identified by the given questId) for the player.
    620     @code
    621     <FailQuest questId="id" />  //Where id identifies the Quest that should be added.
    622     @endcode
    623 
    624     @paragraph CompleteQuest CompleteQuest
    625     This @ref orxonox::QuestEffect "QuestEffect" completes a @ref orxonox::Quest "Quest" (identified by the given questId) for the player.
    626     @code
    627     <CompleteQuest questId="id" />  //Where id identifies the Quest that should be added.
    628     @endcode
    629 
    630     @paragraph AddQuestHint AddQuestHint
    631     This @ref orxonox::QuestEffect "QuestEffect" adds a @ref orxonox::QuestHint "QuestHint" to a @ref orxonox::Quest "Quest" (identified by the given questId) of a player.
    632     @code
    633     <AddQuestHint hintId="id" />  //Where id identifies the QuestHint that should be added.
    634     @endcode
    635 
    636     @paragraph AddReward AddReward
    637     This @ref orxonox::QuestEffect "QuestEffect" adds a @ref orxonox::Rewardable "Rewardable" (@ref orxonox::Rewardable "Rewardable" is an Interface which can be implemented by an object that its creator thinks should be able to be rewarded a player for completing (or failing for that matter) a @ref orxonox::Quest "Quest") to the player. @ref Pickup Pickups for example wold be good @ref orxonox::Rewardable "Rewardables".
    638     @code
    639     <AddReward>
    640         <Rewardable /> //A list of Rewardable objects to be rewarded the player, see the specific Rewardables for their respective XML representations.
    641         ...
    642         <Rewardable />
    643     </AddReward>
    644     @endcode
    645 
    646     @subsubsection QuestListener QuestListener
    647     The @ref orxonox::QuestListener "QuestListener" is the second device you can use to create side effects. As opposed to @ref orxonox::QuestEffect "QuestEffects" (that are executed (or invoked) either as a result of failing or completing a Quest or by a @ref orxonox::QuestEffectBeacon "QuestEffectBeacon"), @ref orxonox::QuestListener "QuestListeners" are passive, meaning that they relay information regarding status changes of @ref orxonox::Quest "Quests" rather than enforcing status changes. @ref orxonox::QuestListener "QuestListeners" have a certain mode (all, start, complete or fail) and a @ref orxonox::Quest "Quest" which they belong to (resp. to which they react). You then can use @ref orxonox::QuestListener "QuestListeners" to make basically any object aware of when the status of the given @ref orxonox::Quest "Quest" changes (the way you defined through the mode) and take any action you may think of.
    648 
    649     Here is an example of the usage of @ref orxonox::QuestListener "QuestListeners" in XML:
    650     @code
    651     <BaseObject> // The object that should react to the status change of a Quest.
    652         <events>
    653             <function> // Where function is the method of the object that schould be executed. Normally this would be visibility or activity.
    654                 <QuestListener questId="someQuestId" mode="someMode" /> // Where someQuestId is the identifier for the Quest the QuestListener is reacting to, and someMode is the kind of status change the QUestListener reacts to (all, start, complete or fail).
    655             </function>
    656         </events>
    657     </BaseObject>
    658     @endcode
    659 
    660     I hope this example has made the usage of @ref orxonox::QuestListener "QuestListeners" a little clearer. The @ref orxonox::QuestListener "QuestListener" actually reacts exactly as any @ref orxonox::Trigger "Trigger" or @ref orxonox::EventListener "EventListener" would (although the @ref orxonox::QuestListener "QuestListener" is really neighter the one nor the other) which means you can use it in exactly the same way you would use one of the above, it just reacts to a different thing. Namely to the change in a @ref orxonox::Quest "Quests" status.
    661 
    662     @subsection PuttingTheQuestsInTheGameWorld Putting the Quests in the game world
    663     As of now we know how to create @ref orxonox::Quest "Quests" and @ref orxonox::QuestHint "QuestHints", we have a way for quests to add new quests, or even complete/fail other quests. We also have a way of reacting to a status change in a @ref orxonox::Quest "Quest". In short we know how quests can be created, how they can influence other quests and how we can react to changes in quests. But our @ref orxonox::Quest "Quests" have no ties (well, not really at least) to the game world as of yet, meaning, that the game world cannot influence quests. For this we have @ref orxonox::QuestEffectBeacon "QuestEffectBeacons".
    664 
    665     @subsubsection QuestEffectBeacon QuestEffectBeacon
    666     The @ref orxonox::QuestEffectBeacon "QuestEffectBeacon" is a @ref orxonox::StaticEntity "StaticEntity" and has the ability to (when triggered trough some circumstance) invoke a specified list of @ref orxonox::QuestEffect "QuestEffects" on the player triggering the @ref orxonox::QuestEffectBeacon "QuestEffectBeacon".
    667 
    668     Creating a @ref orxonox::QuestEffectBeacon "QuestEffectBeacon" in XML goes as follows:
    669     @code
    670     <QuestEffectBeacon times=n> //Where 'n' is either a number >= 0, which means the QuestEffectBeacon can be executed n times. Or n = -1, which means the QuestEffectBeacon can be executed an infinite number of times.
    671         <effects>
    672             <QuestEffect /> //A list of QuestEffects, invoked when the QuestEffectBeacon is executed, see QuestEffect for the full XML representation.
    673             ...
    674             <QuestEffect />
    675         </effects>
    676         <events>
    677             <execute>
    678                 <EventListener event=eventIdString />
    679             </execute>
    680         </events>
    681         <attached>
    682             <PlayerTrigger name=eventIdString /> //A PlayerTrigger triggering the execution of the QuestEffectBeacon.
    683         </attached>
    684     </QuestEffectBeacon>
    685     @endcode
    686 
    687     The @ref orxonox::QuestEffectBeacon "QuestEffectBeacon" can only be executed a defined number of times (where -1 times stands for an infinite number of times) and the @ref orxonox::QuestEffect "QuestEffects" are invoked whenever the method 'execute' is called, which is (indirectly through an @ref orxonox::EventListener "EventListener", because I wanted to attach the @ref orxonox::PlayerTrigger "PlayerTrigger" so that its position is always relative to the @ref orxonox::QuestEffectBeacon "QuestEffectBeacons" position) done by the @ref orxonox::PlayerTrigger "PlayerTrigger".
    688 
    689     A @ref orxonox::PlayerTrigger "PlayerTrigger" is a special sort of @ref orxonox::Trigger "Trigger" that knows the player that triggered it and therefore can be asked who that was. This allows the @ref orxonox::QuestEffect "QuestEffects" to be executed on the right player.
    690 
    691     @section SampleQuest Sample quest
    692     To get your head around all of this and see some of the things mentioned here in action you might want to check out the "The Tale of Princess Aeryn"-Quest (Levelfile: princessAeryn.oxw) in the level-folder.

    49         Implements a Pong minigame.
     49        Implements a Pong minigame (<a href="http://en.wikipedia.org/wiki/Pong">Wikipedia::Pong</a>).
    5050        It connects the different entities present in a game of Pong.
    51        
    52         //TODO: List and add details to different classes used and how.
    53         PongBall, is the ball, PongBats are the things that can be moved by the players (ControllableEntities), PongCenterpoint is the playing field. (x-z area)
     51
     52        - The @ref orxonox::PongCenterpoint "PongCenterpoint" is the playing field for the Pong minigame, it allows for configuration of the minigame, e.g. by setting the size of the playing field, or the length of the @ref orxonox::PongBat "PongBats". The playing field is always in the x,y-plane, the x-axis being the horizontal and the z-axis being the vertical axis.<br />
     53        The Pong class redistributes the important parameters defined in @ref orxonox::PongCenterpoint "PongCenterpoint" to the other entities, that need to know them, e.g. the @ref orxonox::PongBall "PongBall" and the @ref orxonox::PongBat "PongBats".<br />
     54        The @ref orxonox::PongCenterpoint "PongCenterpoint" needs to exist in a level with the @ref orxonox::Gametype "Gametype" <em>Pong</em>.
     55        - The @ref orxonox::PongBall "PongBall" is the ball both players play with. The @ref orxonox::PongBall "PongBall" both implements the movement of the ball, as well as the influence of the boundaries and consequently, also the bouncing (off the upper and lower delimiters, and as off the @ref orxonox::PongBat "PongBats") of the ball and the effects of the failure of a player to catch the ball (i.e. the scoring of the other player).
     56        - The two @ref orxonox::PongBat "PongBats" are the entities through which the players can actively participate in the game, by controlling them. The @ref orxonox::PongBat "PongBat" class manages the movement (and restrictions thereof) and the influence of the players on the bats.
