[FONT=Arial]So ive been struggling with this one for a while, and i have been searching everywhere for an answer, and have had no such luck yet, so maybe someone can save my day for me!
If i have a grid system like this:
1 2 3 4 5 6 7 8 9 a b c d e f g h i j k l m n o p
if i rotate that grid 90 degress, it would then look like this
l g b 6 1 m h c 7 2 n i d 8 3 o j e 9 4 p k f a 5
now, before the rotate, if we pick any point we know the co-ords of, i want to try to find the co-ords after the rotation using some sort of math or function
we know the co-ords of 7 before the rotate are 2,2 and we can look at the grid after the rotate and find out the the co-ords are gunna be 4,2.
Is there any sort of mathamatical formula for this that im somehow nut understanding?
Any help is much apreciated
