wait, so the process is this?: 1. create a ball prop 2. go to "create magnet"... that will parent itself to the ball, right? 3. move ytrans downwards until it touches the matress surface.. or wait, should I just move the ytrans of the zone only? (??) 4. parent the magnet zone to the ball prop... again, or was that already done (sheesh, I'm going backwards) 5. move the ytrans of the ball prop and presto. I'll try this, but I'm sure there's something I'm not fully understanding... thanks!
