[Solved]How do I clamp a sprite within a circle, mouse moved

Hi, I'm trying to create a slingshot system where when the player pulls back the slingshot, it revolves in a smooth semi-sphere behind the slingshot.

I've manage to accomplish this in a box shape working, but I need the smooth movement along a semi-circle, or full circle when the mouse is outside of the range. Try the demo to understand what I mean:

I found this, and am working on it to help me: https://www.scirra.com/forum/viewtopic.php?f=147&t=73855&p=616646&hilit=circle+clamp#p616646 but I unfortunately I just can't figure this out right now.

Does anyone know how to accomplish this, or have ideas to approach? I'm totally stuck at the moment.

Thanks for any help!

Not perfect, but should give you an idea:

You could try something like that (edited capx)
