360 degree dial to control rotation of an object around its z

hey,

I am instantiating 2x of the same gameobject (fence poles)
Then I might end up having e.g. 5 pairs of poles with same names.
I have then made some code where the distance etc. between the pair is computed and fence wires are instantiated.
Since I drag these objects around I would like to execute code for all of them at the end of placing all fences.
Instead of having it all in an update.

I can maybe clarify if its too strange to read
Any ideas?

What's this got do do with dials?

 

sorry. I tried to delete the post.. How do I do that?
