+        Pickups inheriting from this class can choose an activation type and a duration type.
         - The <b>activationType</b> deals with what happens to the Pickup as soon as it is picked up. It can either be set to <em>immediate</em>, which means that the Pickup is activated/used immediately upon being picked up. Or to <em>onUse</em>, which means, that the Pickup will be activated/used if some outside entity (most commonly the player through the PickupInventory) decides to use it. Default is <em>immediate</em>.
         - The <b>durationType</b> deals with whether the Pickup has a continuous effect or whether its effect is focused on a singular instant. It can either be set to <em>once</em>, which means, that the Pickup just has an effect (at a singular instant in time) and is done once that effect has been applied. Or to <em>continuous</em>, which means that the effect of the Pickup unfolds over some timespan. Default is <em>once</em>.

+        It connects the different entities present in a game of Pong.
+
+        - 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 />
+        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 />
+        The @ref orxonox::PongCenterpoint "PongCenterpoint" needs to exist in a level with the @ref orxonox::Gametype "Gametype" <em>Pong</em>.
+        - 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).
+        - 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.

Or more precisely, it makes the ball bounce off then upper and lower delimiters of the playing field, it makes the ball bounce off the bats and also detects when a player scores and takes appropriate measures.

+        The playing field resides in the x,z-plane, with the x-axis being the horizontal axis and the z-axis being the vertical axis.
+        
+        Various parameters can be set:
+        - The <b>dimension</b> is a vector, that defines the width and height of the playing field. The default is <em>(200, 120)</em>.
+        - The <b>balltemplate</b> is a template that is applied to the @ref orxonox::PongBall "PongBall", it can be used to attach different things to it, e.g. its @ref orxonox::Model "Model". See below for a usage example.
+        - The <b>battemplate</b> is a template that is applied to the @ref orxonox::PongBall "PongBat", it can be used to attach different things to it, e.g. its @ref orxonox::Model "Model". See below for a usage example.
+        - The <b>ballspeed</b> is the speed with which the @ref orxonox::PongBall "PongBall" moves. The default is <em>100</em>.
+        - The <b>ballaccfactor</b> is the acceleration factor for the @ref orxonox::PongBall "PongBall". The default is <em>1.0</em>.
+        - The <b>batspeed</b> is the speed with which the @ref orxonox::PongBat "PongBats" move. The default is <em>60</em>.
+        - The <b>batlength</b> is the length of the @ref orxonox::PongBat "PongBats" as the percentage of the height of the playing field. The default is <em>0.25</em>.
+        
+        An example in XML of the PongCenterpoint would be:
+        
+        First the needed templates:
+        The template for the @ref orxonox::PongBall "PongBall".
+        @code
+        <Template name="pongball">
+          <PongBall>
+            <attached>
+              <Model mesh="sphere.mesh" scale="2" />
+              <ParticleSpawner name="hiteffect" position="0,0,0" source="Orxonox/sparks2" lifetime="0.01" autostart="0" mainstate="spawn" />
+            </attached>
+            <eventlisteners>
+              <EventTarget target="hiteffect" />
+            </eventlisteners>
+          </PongBall>
+        </Template>
+        @endcode
+        As can be seen, a sphere is attached as the @ref orxonox::Model "Model" for the @ref orxonox::PongBall "PongBall", and also an @ref orxonox::EventListener "EventListener" that triggers a @ref orxonox::ParticleSpawner "ParticleSpawner", whenever the ball hits the boundaries is attached.
+        
+        Additionally the template for the @ref orxonox::PongBat "PongBat".
+        @code
+        <Template name="pongbatcameras" defaults="0">
+          <PongBat>
+            <camerapositions>
+              <CameraPosition position="0,200,0" pitch="-90" absolute="true" />
+            </camerapositions>

+              <Model position="0,0,3" mesh="cube.mesh" scale3D="14,2,2" />
+            </attached>
+          </PongBat>
+        </Template>
+        @endcode
+        As can be seen, there are actually two templates. The first template is needed to set the camera for the @ref orxonox::PongBat "PongBat". The second template ist the actual template for the @ref orxonox::PongBat "PongBat", the template for the camera position is added and a @ref orxonox::Model "Model" for the @ref orxonox::PongBat "PongBat" is attached.
+        
+        Finally the PongCenterpoint is created.
+        @code
+        <PongCenterpoint name="pongcenter" dimension="200,120" balltemplate="pongball" battemplate="pongbat" ballspeed="200" ballaccfactor="1.0" batspeed="130" batlength="0.25">

+            <Model position="0,0,60" mesh="cube.mesh" scale3D="105,1,1" />
+            <Model position="0,0,-60" mesh="cube.mesh" scale3D="105,1,1" />
+          </attached>
+        </PongCenterpoint>
+        @endcode
+        All parameters are specified. And also two @ref orxonox::Model "Models" (for the upper and lower boundary) are attached.
