The Continuous Tutorial and the Speed of the Balls

I was looking at the tutorial about kirupas Continuous tutorial and i can’t figure how to stop the loss of Bawls. every time i alter the speed of the balls by moving the mouse foward, it allows a large amount of bawls to skip out of the buffer. any help whould be good. :slight_smile:

in the meanwhile, it always work as long as it is in a constint speed, is their a way to keep it in a constint speed never altered by the movment of the mouse?

also,(might as well while i’m asking) is there a way to make it move over the y axis rather the x axis? i tried changing the code to see if it whould happen but for some reason it doesn’t
