Somebody could tell you the right way to do it with maths.
But I often cheat. Connect 2 objects together with a fixed joint. Rotate the central one and get the coordinates of the other.

You could setspriteoffset() and then setspriteangle() to set the rotation

Remember those local axis movements on 3D objects. Like, if you position an object where you need the centre of rotation to be, then rotate it, and move it for the local X Y Z, you can do it with fairly minimalist commands. Considering the maths involved verses just position, rotate, offset - it's a no brainer for me. You can of course position an object with another object, with local X Y Z offsets - like putting a plain at a specific location on a model and then billboarding it to face the camera, like a light effect or something.

The MoveObjectLocalX, Y, and Z commands are very, very useful.
