    public Transform Yrig;//
    // Start is called before the first frame update
    public void Star()
    {
        //创建圆环
        ProBuilderMesh pbMesh = ShapeGenerator.GenerateArch(PivotLocation.FirstVertex,  deg, radius, 0.5f, 1, 20, true, true, true, true, true);
        pbMesh.GetComponent<MeshRenderer>().material = mat;
        
        //使圆环平躺
        pbMesh.transform.Rotate(-90, 0, 0);
        Yrig = new GameObject("yRig").transform;
        pbMesh.transform.SetParent(Yrig,false);

    }

    // Update is called once per frame
    void Update()
