If you have an irregular Area. For exampel these points (x, y): 1, 2 5, 6 3, 4 and back to 1, 2 again. Which would make a sort of triangle. If you want to se if another point (x, y) is within this Area, how would you do?

you have two choices..

1) break your mind trying to do it with plain code and lot of math.. like dividing the triangle in little rectangules..

or 2) use some sort of getpixel function to know the color of the triangle.. an example: in the back (a surface that the player can never see) blit an exact triangle with a color say: 0,0,255.. use a getpiel function.. if you get that color you''re touching the triangle..

hope that helps
