How do i get inputs for a b x and y. Also how do i change the sprites for attacks and animation for movement

The button constants for ABXY are simply #A, #B, #X and #Y. To change a sprite you can just use SPSET again with a different definition number. Animations are a bit hard to make, but if you're willing you can look up SPANIM and the "Anim." tool in the SmileTool.

Also, I suggest using AND instead of == for button input.

Heres what i mean. I want it so that when you press x you change sprites and y to change back. How do i do that?

Simple enough. IF BUTTON() AND #X THEN SPSET 0,<Def 1> IF BUTTON() AND #Y THEN SPSET 0,<Def 2> Where Def 1 and 2 are the definition numbers of the sprites you want to change to.
