# AnchoringComponent.PhysicsSimulation.none

Opts out the entity and its descendants from having their own physics space.

```
case none
```

## Discussion

`none` implies the anchor entity does not have its own physics simulation.

It will use the regular rules to determine which physics simulation the entity is a part of.
For more about the rules, please check [`PhysicsSimulationComponent`](/documentation/RealityKit/PhysicsSimulationComponent).
