Godot: Dragging and dropping physics objects video

Series: 2D Shapes, drag and drop, new objects

Continuing to explore the Godot 3 game engine. I want to make a game where you drag blocks around and balance them on each other, but I couldn't find much documentation on how to drag-and-drop objects (except menu UI elements), and especially I found quite a few wrinkles when doing this with objects that are normally controlled by the physics engine.

This time we actually write some code in Godot's programming language, GDScript.

Godot version: v3.0.6.stable.official.8314054
