Good Day/Night. I'm not sure if I can ask in here, but I'm having a little problem with my prototype game.
So I'm trying to learn OpenGl using GLUT with CodeBlocks, and everything is going well, like, it renders a cube that I can move, but It only moves on the z axis. And I don't know what to do, because I checked everywhere to see if I did something wrong, but there's nothing (I even tried chatGPT to generate me code but it's the same). So I came here to ask if anyone here has any clue on how to fix this, It will be of great help!
Here's the code:
