Thanks for doing all this. I mentioned this thread to a physics listserv frequented by those looking in to effectively teaching same [1]. Your project is geared to students learning to code, which could include future physics engine designers. Great way to get one's feet wet, not just using the c

Hi Eric, Glad the sandbox is working for you! You've got a couple of options for giving the ball a horizontal velocity, depending on what effect you want. If you want an instantaneous horizontal kick, but after that the ball responds normally to gravity, use b1.hit and set the y part of the dire
