void KGrTimer::tick ( bool  missed, int  pScaledTime  )

signal

This signal powers the whole game.

KGrLevelPlayer connects it to its tick() slot.

Parameters

missed	If true, the QTimer has missed one or more ticks, due to overheads elsewhere in Qt or the O/S. The game catches up on the missed signal(s) and the graphics view avoids painting any sprites until the catchup is complete, thus saving further overheads. The sprites may "jump" a little when this happens, but at least the game stays on-time in wall-clock time.
pScaledTime	The number of milliseconds per tick. Usually this is tickTime (= 20 msec), but it is less when the game is slowed down or more when it is speeded up. If the scaled time is 10 (beginner speed), the game will take 2 ticks of 20 msec (i.e. 40 msec) to do what it normally does in 20 msec.
