I know enough math to do this now!!!! What's special, you may ask? Well, you control the x and y velocities with the arrow keys, and the arrow points in the direction that the thing is going. It's probably useful for like a scrolling platformer or something. It's actually harder than it looks, because: 1) scratch's rotation system is clockwise and 0 degrees is up, and the math rotation system is counterclockwise and 0 degrees is to the right 2) the inverse tangent function (getting the angle from the ratio of y/x) gives you an angle between -90 and 90 degrees so that there aren't double possibilities, so you have to take into account when the ratio y:x is the same but the angle is different, which I did by checking when x velocity was negative.
Thanks to trigonometry, Scratch, my math teachers, and this platformer tutorial from 2020 (https://scratch.mit.edu/projects/370583228/) which I've used in so many projects without understanding.
