I’m making a 2D game that is inspired by Earthbound, and I’m wanting to create ‘psychadelic’ combat backgrounds that were in that game. However, I’m kind of a newb when it comes to shader programming. Some of the mode7 effects that were on the SNES included:
A: An effect that would cause a flat texture to distort in a sin-wave pattern
B: Something that would cause a ‘ripple’ effect’
C: A pattern would appear to be constantly moving, so that patterns that go off the edge of the screen ‘appear’ on the other side.
I think I have a good idea what to do, like put a ‘flat’ square in front of the camera and then distort it, or find some way to have the texture move and ‘wrap around’, but I really don’t know where to begin on writing these shaders or where to find them.
And no, I don’t plan on getting Unity Pro for this project.
Any advice?
