## Player (CharacterBody3D) ← 只负责移动与碰撞，自身不旋转
|
||||
## ├─ Collision (CollisionShape3D, CapsuleShape3D)
|
||||
## ├─ Body (Node3D) ← 视觉层，朝移动方向转身；换角色模型时挂在它下面
|

## │ └─ character-male-e2 (Node3D)
|
||||
## │ ├─ character-male-e/Skeleton3D ← 骨骼 + 蒙皮网格（character-male-e.glb）
|
||||
## │ └─ AnimationPlayer ← 动作库：idle / walk / sprint / jump / fall
|
||||
## ├─ CameraRig (Node3D) ← 承担偏航 yaw，独立于本体旋转
|
||||
## │ └─ SpringArm (SpringArm3D) ← 承担俯仰 pitch，自动避障
|
||||
## │ └─ Camera (Camera3D)
|
||||
## ├─ Sync (MultiplayerSynchronizer) ← 同步 position、Body.rotation、health、anim_state、anim_speed
|
||||
## └─ HealthLabel (Label3D) ← 头顶血条（节点配置，不是代码建的）
