I have two vectors.
One is defined by a point (x), a direction and a length.
The other is defined by two points.
How can I find out if they intersect, and if they do the angle that point of collision is at from (x).
Thanks in advanced.

underwaredesign.com might be able to help - if you can convert your own data into 2 sets of 2D lines you could use a line intersect function then take the intersection point and work out the angle from that and the points of each line.
