Hi GL folks.

I'm using glutTimerFunc() to animate the characters in my game.
A friend of mine suggested that I should call glutTimerFunc() before any other code in my Func. However, I was doing the opposite. He even show me that without calling glutTimerFunc() first my drawing rate will differ from one PC to another.

Func(int v){
// First
glutTimerFunc(32, Func, 0);
// My code
}

Func(int v){
// My code

// Last
glutTimerFunc(32, Func, 0);
}

I investigated this subject my trying this:
Func(int v){
int r = rand() % 10;
printf("start\n");
//glutTimerFunc(32, myTimer, 0); // Case #1
sleep(r); // in sec
//glutTimerFunc(32, myTimer, 0); // Case #2
printf("end\n");
}

In both cases, it always kept running Func() until it finishes before calling it once again.
So the pattern was:
start
end
start
end
start
end
..
..

Any opinions, which is correct or both of them????
