Unity Physics Samples

In the Game window:

• Drag objects: click and drag with left mouse
• Rotate camera: click and drag with right mouse
• Move camera: WASD keys

NOTE: Many of these samples display extra information as debug display gizmos in the Editor. For example, the Query samples display raycasts as debug lines that are only visible when Gizmos are enabled.
