Yield in a Cocoa while loop
Post: #4
If you lock everything to say.... 60fps, you can easily add a bit of timing and a usleep for the extra time.
Code:
while (playing) {
NSTimeInterval currentTime = [NSDate timeIntervalSinceReferenceDate];
if (currentTime - _timeOfLastFrame >= 1.0 / _maxNumberOfFramesPerSecond) {
run a frame
} else {
double timeLeft = ((1.0 / _maxNumberOfFramesPerSecond) - (currentTime - _timeOfLastFrame));
usleep(1000000 * timeLeft);
}
}
