So I need a function (parameters: origin x, origin y, destination x, destination y, object x1, object y1, object x2, object y2). The object in this case would be a wall with two points (x1, y1, x2, y2). The function needs to return a true/false if the wall intersects the path. As in, does it cross between the origin and destination. In other words, we have two finite lines (path of movement and wall), and I need to know if they cross.

How do I do that?

I program in basic (small basic) but I would rather if you wouldn't add code, just plain english.

Thanks in advance!
