I now need to do a "distance fro a point to a line" and I'm kinda rusty. Shame on me, really.

First dot the point vector with the line direction, this gives you a scalar, then multiply that scalar with the normalized line direction to get the projected point.

Code:

Global point pos: P
Line point 1: L1
Line point 2: L2

Projected point: pP = dot( P - (L2-L1), normalizecpy( L2-L1 ) ) * normalizecpy( L2-L1 )
Distance = length( pP - P )

At least I THINK that's how it went I suck at vector math
