Unity Physics Samples

For more Phyiscs and DOTS starter material, see the main page of this repo.

Controls

In the Game window:

• Mouse spring : Click and drag with left mouse
• Camera rotate : Click and drag with right mouse
• Camera move : W,A,S,D keys

Debug Display

A lot of the demos display extra information as debug display gizmos in the Editor, for example the Query demos (ray cast, distance cast, etc). This display for these gizmos is in the Scene not the Game window. So keep an eye on both if in doubt:
