how to constrain bodies to integer x/y coordinates

[arahlf]

Is there an easy way to constrain a Body to whole-number coordinates? I'm making a pool game, and the balls often end up with coordinates like:

(585.61932373047, 447.06735229492)

When drawing with those coordinates, the image sprites are somewhat distorted because they are not whole numbers. I've tried rounding the body's x/y values post-update, but that is somewhat problematic because it then triggers additional collisions sometimes.

Any ideas or suggestions?

Thanks!

Simulation-wise it might be better to just round the coordinates while drawing, and have the physics just work with the fractions.
(And rounding is of course math.floor(x+0.5).)

I agree with bartbes. Round the coordinates you draw them at, but leave the real coordinates alone.

I'll give that a try, thanks.
