FlushKeys:Void

Description

Throws away everything the keyboard has recorded so far: the queue of typed characters that GetKey hands out, the keys counted as held for KeyDown and the presses counted for KeyHit. Call it once before a screen that waits for input, such as a menu or a new level, so that button mashing from the previous screen does not skip it. Do not call it every frame, or the program will never see a key.

Differences

• The Device argument is a BlitzLLVM extension: the original has no such argument and only knows one keyboard.
