I was in the middle of a 2d game and I realized that I needed a linesintersect function. I thought it would be simple so I tried to make one and soon realized just how hard it was. I could not find anything in the code archives either. I guess what I am asking is does anyone have a lines intersect function that is efficient and fast? Any help is greatly appreciated :)
