I'm trying to get a ball to bounce up and down but for some reason, after every bounce the ball gains velocity. How can I edit my code so that it keeps bouncing up to the same height?

Take a look at my codebase posting here:
http://darkbasicpro.thegamecreators.com/?m=codebase_view&i=1e21455348816a141a9736ef42154b52

The basic principal being used is:
loop
for each particle
erase particle
position = position + velocity
velocity = velocity + acceleration
draw particle
end of particle loop
end of main loop

Very nice, although a bit too complex for my needs.
I only want one ball to bounce without gaining or losing momentum.
I don't understand what you mean by the particles, I didn't see any mention of particles in the code.

Particle = sphere or ball. Or whatever it is you're trying to bounce.

I've simplified my example to use just one ball and do nothing other than let it bounce.

Best of luck.

Or alternatively if you want the ball to bounce to the same height forever, see source on this message.
