# resetPhysicsTransform(recursive:)

Resets the position, orientation, and velocities of the simulated
physics body.

```
@MainActor @preconcurrency func resetPhysicsTransform(recursive: Bool = true)
```

## Parameters

`recursive`

Apply the reset to all descendant entities.

## Discussion

Call this method only for dynamic rigid bodies, with a
[`mode`](/documentation/RealityKit/PhysicsBodyComponent/mode) of [`PhysicsBodyMode.dynamic`](/documentation/RealityKit/PhysicsBodyMode/dynamic). This is
the only kind of body that’s affected by physics simulations. For all
others, modify the entity’s transform property directly.

Conversely, directly modifying the transform of a dynamic body has no
effect because the physics simulation overwrites it on every frame.
