Thanks, I usually do my own physics but figuring this out in GM2 makes ball physics much better. I be making a proper game out of this soon. Thanks for trying it out. :)
I literally started today using these four tutorials from the game maker website.

Starting from the first one and making there demo to understanding it and making my own game out of what I learned. Hope this helps!
