Threads?

If you are using MFC then it would be easier to use threads. But in my understanding of the spinning cube lesson, is every time the function is called the cube rotates so much. Therefore it would quite difficult to implement a while loop in that function.

I dont know if this helps because my understanding of that lesson is not quite perfect yet.

No amount of genius can overcome a preoccupation with detail.

Why waste threads on that? Most games have a nextThink variable which is compared against the current time (You have to have a timer implemented, look at nehe''s timing lesson). If the nextThink variable is less than the current time you can run the if statement. Here is what I do to update my frameRate variable every second:

void CalculateFPS()
{
	static double nextThink = time;
	static int fps = 0;

	if(nextThink <= time) {
		frameRate = fps;
		fps = 0;
		// Set the next execution to be in 1 second
		nextThink = time + 1.0f;	
	}
	fps++;
}
 

At program start:

lastTime = 0;
currentTime = GetTickCount();
 

then every frame:

currentTime = GetTickCount();

if ((currentTime - lastTime) > 200)
{
     lastTime = currentTime;
     SpinCube();
}

 

Kazade.
