CTriggerVolume defined in triggers.cpp

trigger_transition is a brush entity available in all Source Source games. It controls which entities go through a level transition. Trigger_transitions should be named the same as the info_landmark which is associated with a particular trigger_changelevel. Any entities which are within the trigger_transition brush volume will then go to the next map. The player must also be inside the brush volume.

In Portal 2 Portal 2, transition triggers can also be used with point_changelevel. In this case, the entity does not need to be named.


Name (targetname) <string>
The targetname that other entities refer to this entity by.
