He ended up using this, check the optimizations here! https://scratch.mit.edu/projects/1099079446/ Here, FAJTV, I fixed your oscillation problem! -My solution changes the variable “Angle” by the Speed, then sets the coordinates to the sine of Angle. It’s actually pretty simple once you understand it! -The variable “Limiting Value” makes the speed-to-screen proportion more reasonable (if I didn’t have it a speed of 200 would be way too fast). Change the value as it suits you. If you want to use this, go ahead! Just remember to credit me :) It’s good I’m taking Pre-Cal right now :P
