I've no idea, I'm afraid. No doubt that would come down to another extension somewhere, unless pyglet exposes it somehow. > > Isn't play_frame supposed to take a dt parameter?

Smooth movement requires an unchanging velocity, even if frames are not rendered at exactly equal intervals. So just decide how many pixels per second you want to move (eg. 400), and instead of using the constant 10, use (pixels_per_second * dt). For the smoothest motion, store the accumulated value as a float but pass a rounded version to blit(). > > 10 pixels at > > a time will never look smooth, more so if the time taken to move 10 > > pixels varies slightly from one occurrence to the next. > > Well, I tried 1 pixel at a time, but it takes forever to move the pic, > even with unlimited fps... It would be interesting to know how many fps you actually get when you turn the fps limiting off. Most modern platforms should be able to give you 60-85 with vsync on for a simple scene, and at that frequency you wouldn't need such a high number as 10 pixels each frame. Perhaps there is inefficiency elsewhere in your application that is making frames take a long time. -- Ben Sizer --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pyglet-users" group.
