Bug:Spamming crouch jumps in a trigger can randomly fire OnStartTouch/OnEndTouch. Confirm:Is it a Multiplayer issue only?   [todo tested in ?] 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.
