Pygame - Recolor Pixes Of A Certain Color To Another Using SurfArray (Array Slicing Issue)

I'm trying to make a palette swap functionality for a game, and I'm trying to find a way to change the color of pixels of a certain color to another. I've been able to make all of

Solution 1:

Maybe you're looking for something less general, but there is a replace method in the PixelArray module used for replacing one color with another.

arr = PixelArray(surface)
arr.replace(fromColor, toColor)
del arr

That would change one color on a surface to another. The del statement is there because otherwise the surface remains locked for as long as the PixelArray object exists.

As for the array slicing, a section in the NumPy documentation explains the syntax.
