How do you rotate (90 degree increments) or flip (xflip, yflip) the contents of a ds grid or 2d array without manually rewriting the whole thing? I might also need to x shift and y shift the contents afterward as well.
Arrays don't have any advanced functions and as you can see in the documentation this is not built in for grids so it must be done manually which isn't too hard.
edit: the only thing I found that's already made was a mirror script
