limitFPS

public long limitFPS(long frameIdx,
                     long frameTime,
                     long minFrameTime,
                     org.jagatoo.util.timing.TimerInterface timer)

Limits the FPS to a known value.

Specified by:

limitFPS in interface FPSLimiter

Parameters:

frameIdx - the index of the current frame (zero-based)

frameTime - the time needed to render the current frame (in nano-seconds)

minFrameTime - the minimal frame-time (in nano-seconds) If each frame would take exactly minFrameTime, the desired FPS would be exactly matched.

timer - a TimerInterface to retrieve the current time

Returns:

the wait-time, that is virtually added to the frame-time.
