Copy rotation from child and rotate it from there

Hello! So, I want to make my weapon aim to x point, but since the pivor point isnt in the tip I need to tweak it.

Now I have a empty in the tip of the weapon with a lookat to the point that I want to aim, but now I need to rotate the weapon from that point and copy the childs rotation. What can I do? Thank you

 

I would create a parent object (empty) of which the pivot point (center) is correct and add the script to that.

EDIT: or alternatively if you are using 2D you could go to the sprite and editor and change the pivot point (blue dot)

 

Yeah but for example think that you have a guy holding a stick with one hand and the other tip is on the ground. How do you choose if you rotate it from the hand or from the ground?

 

Are you using 2D or 3D?
