spinal	Morning guys! I'm attempting to limit the speed of Frodo because, well, 75fps is a bit fast for a PAL 8bit. I'm attempting the following, but it seems to be doing nothing at all, Am I heading along the right direction? int Now = GetTicks() + TICKS_PER_SEC/50; if(draw_frame) { TheDisplay->Update(); } int theTime = GetTicks(); while(Now <= theTime){theTime = GetTicks();} --v GetTicks() as you can guess, returns the time in some sort of unit, TICKS_PER_SEC really says it all... -=-=- Check out my excellent homepage!

Jayenkai	Based on my music engine's timing.. ..At Start NextFrame=GetTick()+arbitrary short delay ..In Loop NextFrame=NextFrame+(Ticks_Per_Sec/50); Repeat // Do Nothing (and/or do background stuff!) Until GetTick()>=NextFrame --v If you rely on "GetTicks+" then you'll find it's not entirely stable. If the frame is delayed by 2 ticks, then the next GetTicks+ will be 2 ticks out, and so on and so forth, exponentially getting slower and slower.. Or at least, off "tempo". Keeping the NextFrame, and upping it yourself by a predetermined amount, will ensure that the next frame is always roughly in the correct timing area, even if the GetTicks is slightly delayed.. -=-=- ''Load, Next List!''
