I don't get it. I've wrote something like this: my.pan = 0;wait(-5);my.pan = 180; and everything looks ok! I've been changing max fps from 40 to 200 and still works fine to me. You have to ask conitec what's going on.
When I press F11 at runtime, the fps is about 1764, all my testing codes are work correctly when I set fps_max <= 250. May be wait(-time) only works under this value or just only my PC.
@ the guitar well.. for me it works just use fps_max, fps_min and do be safe lock_fps... or fps_lock so much problems solved only because I locked the framerate. and I mean real problems, problems that destorys the gameplay on slower PCs etc.
