public enum TouchPhase
No activity has been registered on the touch yet.
A touch has just begun, i.e. a finger has touched the screen.. Only the first touch input in any given touch will have this phase.
An ongoing touch has changed position.
An ongoing touch has just ended, i.e. the respective finger has been lifted off of the screen. Only the last touch input in a given touch will have this phase.
An ongoing touch has been cancelled, i.e. ended in a way other than through user interaction. This happens, for example, if focus is moved away from the application while the touch is ongoing.
An ongoing touch has not been moved (not received any input) in a frame.
