Bug Trying to make physics based drag, coming out as buggy and non-functional

Hello.
I am a new unity creator, and right now I am working on a game similar to Google Gravity if you've ever seen that.

I am trying to make a special type of drag and drop which can pick up parts that have Rigidbody's (for Physics) at specific points on the part by adding a HingeJoint2D to them and trying to set the anchor of it to the part's position + the offset of my mouse when I selected the part.

So far this hasn't worked and there's another thing that isn't working either.

Like, being able to throw them around the place (They just ignore sideways force when let go and fall straight down).

Any help is appreciated!

 

How would I go about writing the code to drag a part using this method then?

(Not a script for each individual part, instead a script to go on something global that says you can drag on parts with a certain layer named "Draggable")

 

Ah, thanks! This really helped me. Topic has been solved
