to start bouncing, click and drag the ball, then let it go ! the further you drag it from its starting point, the faster and longer it will go. + try playing with the "bounce" and "gravity" variables to see how it will affect the ball's velocity :] [ space ] = toggle the visibility of the changeable variables. [ o ] = toggle the visibility of technical variables (exact velocity + more). [ t ] = toggle the ball's trail.
just a project to test basic bouncy ball physics; it may be useful in future projects ^_^
