Okay, one last thing. Once the trigger is touched, it won't stop making balls after having dealt with the initial collision. I have theorized it may be the balls triggering the trigger again, but I have set both ball and trigger to "collisionSet:=3" so they won't collide with self.
Nope, still infinite ballrain.
I have no idea what a cvt is, and my previous engine design that didn't *cheat* was way less powerful. Besides, my scripting is horrible, and I find scripint also *cheating* as it artificially moves things, just like an axle hinge.
