source: code/trunk/src/modules/objects/triggers/DistanceMultiTrigger.h @ 7138

Last change on this file since 7138 was 6906, checked in by dafrick, 15 years ago

Added DistanceTriggerBeacon, which is a device which can be attached to objects to trigger a DistanceTrigger (both the (single) DistanceTrigger and DistanceMultiTrigger) based on the name of the DistanceTri$
Also some minor adjustements in QuestEffectBeacon: Removed some output and adjusted the outputlevel of some other output.
And started working on PickupInventory again (though no significant changes yet).

49    @brief
[6906]50        The DistanceMultiTrigger is a trigger that triggers whenever an object (that is of the specified target type) is in a specified range of the DistanceMultiTrigger. The object can be specified further by adding a DistanceTriggerBeacon (just attaching it) to the objects that can trigger this DistanceMultiTrigger and specify the name of the DistanceTriggerBeacon with the parameter targetname and only objects that hav a DistanceTriggerBeacon with that name attached will trigger the DistanceMultiTrigger.
