Say I have two points, A and B. Their positions are stored in vectors. Now, if I want to get point A to move toward point B, is it ok to do this:- Subtract point A from point B. Take the result and normalise it. Multiply it by a constant, if I wish to alter the speed. Add it to point A to move it. Repeat. Thanks!

Yep, that's how I'd do it.

It should be B - A though, for it to move from A to B [smile].

If at first you don't succeed, redefine success.
