I am following the excellent jit.phys video tutorial
and have successfully created a bouncing ball, gravity and a moving floor (or 'paddle')
and have encountered a minor issue. As part of a larger patch, wherein the user (via force-sensing resistor -> gui slider) can hit a ball into the air by moving the onscreen paddle, occasionally the ball will pass through the floor, especially when the floor is moved very quickly. I have attached a small patch below to demonstrate (my 'net computer has issues with jit.phys, so apologies for the non-compressed file).
Thanks for any suggestions
