So if i'm understanding this right and from looking at the used function.
You are checking if the player is touching any triggers that is range.
The difference between 'isTouching' and this new function is that the default 'isTouching' requires you to specify the entity that you want to check.
PHP Code:
self isTouching(entity)
self isUseTouching()
The function that you are using is called 'G_TouchTriggers'.
If i'm right it should return which entity you are triggering at the moment.
So maybe call the function: 'player getActiveTouchTrigger() or player getCurrentTouchTrigger()' (in case it does return an entity).
Edit: it doesn't return a entity. But it does notify the entities that someone triggers them.
