Defined in: packages/core/src/ui/follow.ts:44
Makes an entity follow a target Object3D with optional rotation behavior.
Remarks 
PivotYkeeps the follower level while rotating around the Y axis to face the target.FaceTargetfully rotates to look at the target.NoRotationonly moves position.
Example 
ts
entity.addComponent(Follower, {
  target: xrRig.head,
  offsetPosition: [0.25, -0.2, -0.35],
  behavior: FollowBehavior.PivotY,
  speed: 5,
  tolerance: 0.3,
})
