How to make horizontal sliding Compass

ı want to make horizontal sliding Compass for my plane’s HUD . I read similar posts but i couldn’t find a way to do that . (I’m a newbie on Unity and ı don’t know so much how to deal rotation , angle etc. )

I was looking for some kind of tutorial also, but I kinda know the basic principle, create an empty game object (in the Hierarchy, create > empty)
and move it to the spot where your north pole should be, then reference this article: Unity - Scripting API: Vector3.RotateTowards you could also reference the roll a ball tutorial, in which the camera is a child of the ball but rotates the opposite way the ball does so that the camera doesn’t SPIN LIKE CRAAAZY! so maybe you could use the basic principles in that script, btw the roll a ball tutorial is right here:Unity Connect
