# BobConfig

> Talos 0.6 · Since 0.6

The walk bob: a cycle that advances with the distance the target walks, at an amplitude that grows with its speed.

It moves the view-model (`ViewModel`, from {@link FirstPersonRig.bob}) and, only when `camera` asks, the eye.

## Signature

```ts
export interface BobConfig {
  /** Metres walked per full cycle (two steps). Default 2. */
  stride?: number
  /** Horizontal speed, m/s, at which the bob reaches full amplitude. Default 4. */
  fullSpeed?: number
  /**
   * Metres the eye dips at full bob. Default 0: only the view-model bobs. A moving eye is the motion
   * that makes some players sick (and every VR player), so it is opt-in and small: 0.02-0.05.
   */
  camera?: number
}
```
