line crossing another line
BlitzMax Forums/BlitzMax Programming/line crossing another line

| I think I've seen this answered on here before, I'm not sure. I'm looking for code that will tell me if a line is crossing another line. I guess there would be four coordinates, the x and y of the first line and the x and y of the second line. Anyone know how to test if they are crossing? |
