Inputs

TurnOn <void>
Turn xog on.
TurnOff <void>
Turn xog off.
BaseTrigger
Toggle
Toggles this trigger between enabled and disabled states.
Enable
Enable trigger
Disable
Disable trigger
TouchTest  (in all games since Source 2007)
Triggers either the OnTouching or OnNotTouching outputs for whether anything is touching this entity.
Icon-Bug.pngBug:Sleeping prop_physics will never fire "OnTouching". Also applies to entities using prop_physics as base.  (tested in: Half-Life 2)
StartTouch  (in all games since Source 2007) !FGD
Behave as if the !caller entity had just entered the trigger volume. Accepts non-physical entities.
EndTouch  (in all games since Source 2007) !FGD
Behave as if !caller had just exited the trigger volume.
DisableAndEndTouch  (only in Source 2013 MultiplayerTeam Fortress 2 branch)
Disables this trigger and calls EndTouch on all currently-touching entities.


Outputs

BaseTrigger
OnStartTouch
!activator = entity that caused this output
!caller = this entity
Fired when a valid entity starts touching this trigger.
OnStartTouchAll
!activator = entity that caused this output
!caller = this entity
Fired when a valid entity starts touching this trigger, and no other entities are touching it. If there are any other entities touching the trigger when a new one begins to touch, only OnStartTouch will fire.
OnEndTouch
!activator = entity that caused this output
!caller = this entity
Fired when a valid entity stops touching this trigger.
Note.pngNote:Will also fire for entities touching it when trigger is disabled via Disable input
Warning.pngWarning:This includes entities which are deleted while inside the trigger. In this case !activator will be invalid.
Warning.pngWarning:OnEndTouch can fire before OnStartTouch under certain circumstances[How?] where both are fired on the same tick and each have the same delay.
Note.pngFix:Add a slight delay to OnEndTouch.
OnEndTouchAll
!activator = entity that caused this output
!caller = this entity
Fired when all valid entities stop touching this trigger.
OnTouching  (in all games since Source 2007)
!activator = !caller = this entity
Fired if something is currently touching this trigger when TouchTest is fired.
OnNotTouching  (in all games since Source 2007)
!activator = !caller = this entity
Fired if nothing is currently touching this trigger when TouchTest is fired.


Issues

Xog incorrect work with $translucent

Xog all time fully rendering through everything with material shader parameter $translucent. This happen because of game can't tell the depth of scene because of the transparency.

  • No $translucent. Behind the wall placed xog volume and some models with small room.

  • With $translucent. Now player see everything, but only what in xog.

Similar issue happen if use $alphatestreference incorrectly.
This problem also applies to brushes which not have $translucent, but which parented to brushes that have this parameter. Similar will happen if brush with $translucent is part of your brush entity. Same will happen if you use overlays/decals on brushes with $translucent.

  • Metal speaker is overlay that use $alphatest, but xog fully visible anyway, because overlay pasted on the transparency window.

This issues doesn't happen if replace LightmappedGeneric to ShatteredGlass shader. ShatteredGlass give similar to LightmappedGeneric results, so, you can use it for glass or transparency surfaces when it's needed.

In some cases use $alphatest if it'll give similar to $translucent resualts.
