The Device Input functions are all fine and well for dealing with simple on-screen touches or getting device orientation, but sometimes you'll want your projects to detect more complex things, like being able to drag or "flick" an instance across a room.

The functions listed here are all designed to give you greater control over how and when these events will be triggered.
