Attached is some source code I've been playing with. I'm trying to come up with an approximate simulation of gravity between a very massive (but inertia-less) mouse cursor and a handful of semi-massless circles.
For a test, I'm only simulating a single body. This world program will render the first few frames, and then stop rendering while the updates just keep ticking away. I have no idea why this is happening, and I'm hoping that somebody could point out what I'm doing wrong (aside from the displayln's, which I know will slow it up some). -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
