I miss a touch function / feature:
Detecting when a Instance (Object) is not longer touches.
Instances of a sprite object a placed side by side (like a keyboard).
This instances can touched using "is touching object". But there is no event who detect when this instance is no longer touches. The "Is touching object" (on a family btw.) checks ALL objects. And when you swipe from one to the another same object. the event still triggered.
Understood what I mean? ^^ Hard to explain. eng. is not my main tongue. Just ask me on any question.
