1.Add grabbable hats to the scene

2.Turn the hook into a simple socket

• 在挂帽架下添加empty【Socket】 → 为empty添加sphere collider作为范围触发检测（勾选is trigger）
• 添加 XR socket interactor
  • attach transform
• 在empty【Socket】子集下添加empty【Attach】作为目标变换参考

3.Duplicate the sockets and attach hats by default

• starting selected interactable - 可在初始化时把物件先挂上去

4.Make your head a socket for hats

5.Prevent other objects from acting like hats

• 使用 Interaction Layer Mask 控制作用范围

  

Challenge 1 - Architecture Review

Bonus task hints:

6. Look in the XR Ray Interactor component to edit the line’s shape and the XR Interactor Line Visual component to edit its colors. 更改指示射线形状

7. Make sure your audio source is set to the 3D “Spatial Blend,” then, if you want, use the OnTimedInterval and PlaySoundsFromList components to randomize the bird sounds. 添加声音的方式
