Hello everyone,
I made a game that uses many timers throughout the code. However the timer has to deal with many tasks in such a small amount of time which leads to the problem where there is lag in my game. For example, my timer runs at an interval of (0.05) and it needs to draw and update many of the images on the screen. Is there any way I can distribute the work flow so that the program runs much smoother?
Thanks
Kevin
I would use an NSThread instead of an NSTimer. I have had more success in this area using NSThread because it runs on an independant thread and is not fired off your main ui thread. In the loop for the thread sleep it for 1/20 (your 0.05) of a second. Because the thread is not running on the UI thread all of its tasks should not slow your UI down. However beacsue it is not running on the UI you will have to call performSelectorOnMainThread to get the UI to update from this background thread. I put a lock on my update method (a simple boolean) that says if the last ui update has not happened, just skip this one. then if im running out of processing time i just drop a frame or two here and there. I also do a lot of checking to see if anything has actually changed before i redraw.
