Question

I am trying to make a simple application that turns a character to look at a vector relative to it’s current position.

The rotation value ranges from 0 – 180 and -180 – 0.

Math is not my strong point and I’d appreciate it if C# code examples could be explained, I need a value to set into the rotation variable in the ranges mentioned above.

Answer 1

Use the Atan2() function to convert relative x, y position into angles

        double dx=target.X-actor.X;
        double dy=target.Y-actor.Y;
        double angle=Math.Atan2(dy, dx)*180/Math.PI;
