Given a 3D positional vector p1 which also has an accompanying directional vector v1, how can i make p1''s direction vector point at any arbitary point? To put this in more of a context p1 is the position of an enemy in a 3d landscape, the enemy has a position and a ''look'' vector. I want to set that look vector to point to any point i pass the function.

guy.directionVector = thingToLookAt.position - guy.position;
guy.directionVector.Normalize();

well, it depends on how your direction vector is like. if it is just a x,y,z pointing in the direction, then it should work... unless i incidently swapped thingToLookAt and guy positions
