1、在spine的物件下建立物理骨骼並選擇”follow”

2、如果該spine動畫已經由美術添加了BoundingBoxes，那在相應的骨骼節點就可以自動生成多邊形碰撞體，點選上圖（weapon2）

3、由於專案要求可以替換武器，也就是更換了spine的skin之後，碰撞體也要同時重新整理

 功能程式碼段

    private void freshWeapon(){
        Destroy(weaponBone.transform.FindChild("[BoundingBox]weapon2").gameObject);
        // 因為這裡的AddBoundingBox不會自動重新整理已經存在的屬性值，所以要先把之前的destroy掉
 

        weaponBone.AddBoundingBox(skeleton.skin.Name,"weapon2","weaponBJ");
        weaponBone.transform.FindChild("[BoundingBox]weapon2").gameObject.AddComponent<WeaponCollision>();
        // weaponBone.DoUpdate(SkeletonUtilityBone.UpdatePhase.Complete); 這個重新整理函式不呼叫也沒區別
    }

   public void DressUp(Skeleton skeleton,string skinName)
   {
      skeleton.SetSkin(skinName);
   }

    void Update () {
        if (Input.GetKeyDown(KeyCode.A)){
            SpineTool.Instance.DressUp(skeleton,"weapon"
 
);
            freshWeapon();
        }
        else if (Input.GetKeyDown(KeyCode.B)){
            SpineTool.Instance.DressUp(skeleton,"weapon2");
            freshWeapon();

        }
        else if (Input.GetKeyDown(KeyCode.C)){
            SpineTool.Instance.DressUp(skeleton,"weapon3");
            freshWeapon();

        }
