Trigger push

Template:Base brush It is a trigger volume that pushes entities that touch it, except those with a parent.

In code, it is represented by theCTriggerPushclass, defined in thetriggers.cppfile.

Keyvalues

Push Direction (Pitch Yaw Roll) ([todo internal name (i)]) <angle>

Angles indicating the direction to push touched entities.

Speed of Push ([todo internal name (i)]) <integer>

The speed at which to push entities away, in inches / second.

Scale force for alternate ticks ([todo internal name (i)]) <float>

If nonzero, scale the force by this amount when running with alternate ticks. This fixes problems with an overly large force due to the longer frametime on when running with sv_alternateticks 1.

Only Falling Players ([todo internal name (i)]) <boolean> (in all games since )

Only affect players if they are falling (and not pressing jump)

Player fall speed ([todo internal name (i)]) <float> (in all games since )

Player must be falling this fast for push to happen

Flags

• 128 : Once Only (possibly means set velocity rather than apply acceleration)
• 256 : Affects Ladders (Half-Life 2)

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.

• 4096 : Disallow bots

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.
