Yes, I knew that the title would catch your attention.

First off, I want to get a vector that starts at self and ends in self.target. The code should be something like

, right?

Now, with which commands can I get information about the vector, like the angle it has?

vector.AbsRadAngle for angle in radians.
vector.AbsDegAngle for angle in degrees.

It was that easy?
Thanks.

Alternately, in more general cases, you can get the angle between two cartesian coordinates with math.atan2.
