I saw the gravity demo video by @GoranMilovanovic and it was pretty cool. Unfortunately, it didn't help with my specific situation for two reasons.
I'm mainly trying to do my game with just logic bricks
my "planet" is a torus, not a sphere.
I need a workflow that will allow me to have an object always point toward the nearest portion of the torus (may need some code for that one), and then fall toward it. Unfortunately, linear velocity doesn't seem to be working, and neither does track to. is there a better way to do this?
