Visualization of disintegration effects, from left to right: Energy, Light electrical, Heavy Electrical
trigger_physics_trap is a brush entity available in 
Half-Life 2 series.
A volumetric trigger that disintegrates entities. It is used extensively in Citadel levels of Half-Life 2 within Combine generators and ball spawners. It disintegrates physics objects and enemies that enter it's volume with a selected visual effect.
Keyvalues
- Name (targetname) <string>[ Edit ]
- The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g.
parentname or target).
Also displayed in Hammer's 2D views and Entity Report.
- Dissolve Type (dissolvetype) <choices>
- Dissolve effect type.
- 0 : Energy
- 1 : Heavy electrical
- 2 : Light electrical
BaseTrigger
- Filter Name (filtername) <filter>
- A filter entity to test potential activators against.
- Start Disabled (StartDisabled) <boolean>
- Stay dormant until activated (with the
Enableinput).
|
- Pitch Yaw Roll (Y Z X) (angles) <QAngle>
- This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.
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
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
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.
