Re: [pygame] Gradient Algorithm

[Patrick Mullen]

Could you modify it so that it can handle horizontal or diagonal gradients as well?  Horizontal is easy, I'm not sure about diagonals though.  I guess you would have to increment y and x by their own separate speed for each iteration and then draw a line from 0,y to x,0.  But that only works for top-left to bottom-right diagonals.  I guess it needs a special case for all 4 diagonals, and horizontal, and vertical :)
