logic_eventlistener is a point entity available in all Source Source games since Portal 2 Portal 2. It is also available in Team Fortress 2 Team Fortress 2.

It can listen to events fired from code and fire and output when it happens.

All event declarations can be found in these files:

resource/gameevents.res
resource/modeevents.res
resource/demoimportantevents.res
resource/serverevents.res
resource/hltvevents.res
resource/replayevents.res 
Icon-Bug.pngBug:In singleplayer, the entity will stop working (firing outputs) after a save is reloaded, and must be respawned with a point_template.  [todo tested in?]
Icon-Bug.pngBug:In Team Fortress 2, when overtime is reached in KOTH maps, the entity does not fire on the teamplay_overtime_begin and teamplay_overtime_end events.  [todo tested in?]
In code, it is represented by the CLogicEventListener class, defined in the logic_eventlistener.cpp file. It is a subclass of both CLogicalEntity and CGameEventListener.
