I can't find any tutorial on this, nor I have any clue on how to make this.
In-game you can pick up unanchored objects, move them around, and when you release the mouse the object drops to the ground, like in Half-life 2.
This is the only thing I could find v

Im sorry if this sounds like a request, I just have nothing to work with.
