Im trying to get a bouncing ball effect ie like the keepy uppy games
ie ball goes up in air and back down in a parabolic curve.

does anyone know of a good equation that would do this. obviously it would effect x and y but also have another variable to decide on the height of the curve and distance it travels.

any help welcome

try subtracting a gravity constant from your yvelocity every loop.

Is this like you want?

use the SIN command. I don't really know what the equation is, but it involves SIN.

Ive managed to come up with 2 equations that work really well allowing gravity, xvelocity and y velocity to be modified to create lots of different arcs

thanks anyway
