| GetIntersect ( System.Vector2 line1From, System.Vector2 line1To, System.Vector2 line2From, System.Vector2 line2To ) : Vector2? |
Returns the intersection of the two lines (line segments are passed in, but they are treated like infinite lines) Got this here: http://stackoverflow.com/questions/14480124/how-do-i-detect-triangle-and-rectangle-intersection |
