3 things so far:
Use collision to spawn balls, then you ensure that only 1 ball is spawned (Spawning lots of balls is NOT good)
Put boxes instead of polygons to the pistons (with that shape you're losing energy, and also boxes are better than polygons, at least at lower densities)
Make the place between the piston and the block head smaller (this will impulse the ball you spawned downwards)

Also, if you want, use GUN tech. Look for my W16 or any other spawn engine here to see waht I mean. It's just an A-shape that impulses the ball downwards

thank you . i was scared nobody gonna help me
