Hello,

I'm doing a demo where i need to know if two lines ( x1,y1,x2,y2 first x3,y3,x4,y4 second line ) are cross. Otherwise, i need a line colision algorithm, i have one but i'm sure that using math i can obtain a better performance.

Thanks :blush: .

Hmmmmm having to write a piece of code that solves simulataneous equations is apparent. I may have a go at that soon.
