Let's say i have two cones in the scene and one of them must point to another cone.
And it should do this smoothly ( i mean turning ).

If i understand it correctly i need a way to find angle (difference) or something between 2 points (X,Y) and then rotate until one cone is pointed "looking" at (to) another cone. I must somehow align one vector to another.

Is there any command that makes these things easier?
