# Unity Physics Samples
*For more Phyiscs and DOTS starter material, see the [main page of this repo](../README.md).*
## 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:
