Damage Model ([todo internal name (i)]) <choices>

How damage is dealt. Normal always does the specified amount of damage each half second. Doubling starts with the specified amount and doubles it each time it hurts the toucher. Forgiveness means that if the toucher gets out of the trigger the damage will reset to the specified value. Good for making triggers that are deadly over time without having to cause massive damage on each touch.

• 0 : Normal
• 1 : Doubling w/forgiveness

Zero Damage Force ([todo internal name (i)]) <boolean>

Should the damaged entity receive no physics force from this trigger.

Inputs

SetDamage <floatRedirectInput/float>

Set a new amount of damage for this trigger.

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

OnHurt

Fired whenever this trigger hurts something other than a player.

OnHurtPlayer

Fired whenever this trigger hurts a player.

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.
