What I mean is, the game loop would run at a fixed rate, but independently of the displaying rate. Practicaly, the class Time would store the current time in a member variable, so each call to Time::GetTime() would give the same value for a same frame, independently of the time elapsed since the last frame. In the game loop, we would put a Time::Refresh() that increase the value of the time by 20ms or something like that (it limits the max frame rate to 50 fps, the same limit we have currently in the physic engine). Then we compare the time variable to the time reported by SDL, and there we decide wether we have enough time to display the frame, or just skip it. The difference with the current main loop, is that we will run more often the Refresh methods and check for keyboard and mouse interaction. Most of the current Refresh methods is to call the physic engine loop, so the impact there is null, the loop is just at an other place. So the main difference is that we'll check more often for user interaction, which is negligeable I think.
Also I forgot to tell, it's a future work, I don't intend to do any of this before 0.8!! :) Lodesi -- _______________________________________________ Wormux-dev mailing list Wormux-dev@gna.org https://mail.gna.org/listinfo/wormux-dev
