Nearly all 2D games require you to click or touch to drag objects around the scene. E.g., in a jigsaw game. This tutorial shows two methods for doing this within Unity.

The first method is a script which you can attach to any object you wish to move. This utilises the OnMouseDown and OnMouseUp methods.

The second is to create a central manager for moveable objects. This will cast a ray using Physics2D.Raycast when you press the mouse button to detect objects. It uses a layer mask to determine which objects in the scene can be moved.
