1000 msecs=1 second
But that works and it really sleeps for about a second - even on windows. So... most likely your code is to blame.
Well, in general that approach is flawed. Different machines have different speed. Each frame takes more or less time... so you actually need to determine how many time elapsed and adjust the wait time span accordingly.
If you're using 1.5, it's easy, because you can use nanoTime().
Like so:

{
long gapTo = frameFraction + timeThen;
do
{
Thread.yield();
timeNow = System.nanoTime();
}while(gapTo > timeNow+timeLate);
if(gapTo<timeNow)
timeLate = timeNow-gapTo;
else
timeLate = 0;
timeDelta = timeNow - timeThen;
timeThen = timeNow;
} |
You can ignore (remove) the timeDelta bit if you want to use tick based animation.

There are tons of information out there. gamasutra.com and nehe.gamedev.net for example.
