I'm currently using Kaan Alpar's "How to Make Asteroids" video as a guide, and so far things have been going great! However, when I got around 18 minutes in with a laser's movement, the code stopped being nice with me. I'm quickly learning how to hate. I've gone as far as copying in the code word for word and it's still failing, the idea is to get the laser moving upward and it's staying static right now.
On the right is a shot of the working code for reference, can someone help me?
