This entity is
not in the
FGD by default.
It should not be put directly in a map because it is generated automatically in code and crashes the game if placed directly.Template:Entity It is the actual trigger used by a prop_floor_button, prop_floor_cube_button, or prop_floor_ball_button to detect objects. When placed in a map directly, the game will crash as the entity keeps a reference to the button it is tied to, which can only be set through code. A trigger_multiple should be used instead as it functions almost identically.
Tip:The auto-generated triggers use their oriented bounding box as the detection area, so the SetSize() VScript function can be used to resize the trigger.Keyvalues
- Delay Before Reset ([todo internal name (i)]) <float>
- Delay in seconds before OnTrigger can fire again, 0 defaults to 0.2. If set to -1, it will kill itself when triggered (as trigger_once), which means outputs like OnEntireTeamStartTouch can never fire.
BaseTrigger
- Filter Name (filtername) <filter>
- A filter entity to test potential activators against.
- Start Disabled (StartDisabled) <boolean>
- Stay dormant until activated (with the
Enableinput).

Flags
BaseTrigger
- Everything (not including physics debris) : [64]
- Clients (Survivors, Special Infected, Tanks
  ) : [1]
- Only clients in vehicles : [32]
- Only clients *not* in vehicles : [512]
- Disallow Bots (removed since ) : [4096]
- NPCs (Common Infected, Witches ) : [2]
- Only player ally NPCs : [16]
- Only NPCs in vehicles (respects player ally flag) : [2048]
- Physics Objects (not including physics debris) : [8]
- Physics debris (include also physics debris) : [1024]
Pushables (Passes entities with classname func_pushable) : [4]  - Deprecated.
Equivalent to using Everything + filter_activator_class that filters func_pushable.

Inputs
- TouchTest
- Tests if the trigger is being touched and fires an output based on whether the value is true or false.
BaseTrigger
- Toggle
- Toggles this trigger between enabled and disabled states.
- Enable
- Enable trigger
- Disable
- Disable trigger
- TouchTest (in all games since
 )
- Triggers either the OnTouching or OnNotTouching outputs for whether anything is touching this entity.
 Bug:Sleeping prop_physics will never fire "OnTouching". Also applies to entities using prop_physics as base. (tested in:  )
- StartTouch (in all games since ) !FGD
- Behave as if the !caller entity had just entered the trigger volume. Accepts non-physical entities.
- EndTouch (in all games since ) !FGD
- Behave as if !caller had just exited the trigger volume.
- DisableAndEndTouch (only in
  )
- Disables this trigger and calls EndTouch on all currently-touching entities.

Outputs
- OnStartTouchAll
- Fired when an entity starts touching this trigger, and no other entities are touching it. Only entities that passed this trigger's filters are considered.
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:Will also fire for entities touching it when trigger is disabled via Disable input Warning:This includes entities which are deleted while inside the trigger. In this case !activator will be invalid.Warning:OnEndTouch can fire before OnStartTouch under certain circumstances[How?] where both are fired on the same tick and each have the same delay. Fix: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 )
- !activator = !caller = this entity
Fired if something is currently touching this trigger when TouchTest is fired.
- OnNotTouching (in all games since )
- !activator = !caller = this entity
Fired if nothing is currently touching this trigger when TouchTest is fired.
