source: code/trunk/src/modules/objects/triggers/DistanceTrigger.h @ 11835

Last change on this file since 11835 was 11083, checked in by muemart, 9 years ago

Fix some clang-tidy warnings.
Also, Serialise.h was doing some C-style casts that ended up being const casts. I moved those const casts as close to the source as possible and changed the loadAndIncrease functions to not do that.

64    @brief
65        The DistanceTrigger is a Trigger that triggers whenever an object (that is of the specified target type) is in a specified range of the DistanceTrigger. The object can be specified further by setting the <em>beaconMode</em> and attaching a @ref orxonox::DistanceTriggerBeacon "DistanceTriggerBeacon" to the object.
66        Parameters are (additional to the ones of Trigger):
67        - @b distance Which specifies the maximum distance at which the DistanceTrigger still triggers, i.e. its range. Default is <code>100</code>.
68        - @b target Which specifies the class of objects that can trigger the DistanceTrigger. Default is <code>"Pawn"</code>.
69        - @b beaconMode Which specifies, whether the DistanceTrigger operates on @ref orxonox::DistanceTriggerBeacon "DistanceTriggerBeacons" or not. If <em>off</em> the DistanceMultiTrigger works as usual. If set to <em>identify</em> the DistanceTrigger is only triggered by objects that have a @ref orxonox::DistanceTriggerBeacon "DistanceTriggerBeacon", with the same name as specified in <em>targetname</em>, attached to them. If set to <em>exclude</em> the DistanceTrigger is only triggered by objects that don't have a @ref orxonox::DistanceTriggerBeacon "DistanceTriggerBeacon", with the same name as specified in <em>targetname</em>, attached to them. Default is <em>off</em>.
[8706]70        - @b targetname Which specifies the name @ref orxonox::DistanceTriggerBeacon "DistanceTriggerBeacons" need to have to make the DistanceTrigger react to them if it is in <em>beacon-mode</em> (the beaconMode is not <em>off</em>).
[2029]71
[8213]72        A simple DistanceTrigger could look like this:
73        @code
74        <DistanceTrigger position="0,0,0" switch="true" target="Pawn" distance="20" />
75        @endcode
[2029]76
[8213]77        An implementation that only reacts to objects with a @ref orxonox::DistanceTriggerBeacon "DistanceTriggerBeacon" attached would look like this:
78        @code
79        <DistanceTrigger position="0,0,0" target="Pawn" beaconMode="identify" targetname="beacon1" distance="30" />
80        @endcode
81        This particular DistanceTrigger would only react if an object was in range, that had a @ref orxonox::DistanceTriggerBeacon "DistanceTriggerBeacon" with the name <em>beacon1</em> attached.
