here is the problem:
i need to move object in a certain moment with basic equatations like s=a*(t*t)
time (t) is like (now-startTime)
now=driver->getTimer()->getTime() and so is startTime called before
but i have problem,on faster computer movement isnt the same like on slower ones,how to solve this?

startTime=driver->getTimer()->getTime() is called before
while(device->run())
{
now=driver->getTimer()->getTime();
}

You'll need to write some code like this:

Code: Select all


long lasttick;

void MainLoop()
{
	Render();  // draw a frame

	if (driver->getTimer()->getTime() > lasttick + 10) {
		lasttick = driver->getTimer()->getTime();
		Tick();
	}
}

Using this, the tick() function is called at 10 millisecond intervals, and providing that your code within tick() is executed in under 10ms then time will remain steady between CPU's.
