靶子旋转 RotateSelf

public class RotateSelf : MonoBehaviour {

    public float speed = 90;
	
	// Update is called once per frame
	void Update () 
	{
        transform.Rotate(new Vector3(0, 0, -speed * Time.deltaTime));
	}
}

// Vector3(x,y,z)对应(红，绿，蓝)

//旋转修改z，像塑料小陀螺的小柄

针头 PinHead

//触发检测，调用游戏结束的方法

public class PinHead : MonoBehaviour {

    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.tag == "PinHead")
        {
            GameObject.Find("GameManager").GetComponent<GameManager>().GameOver();
        }
    }

针 预制体 Pin

游戏控制器 GameManager

(了解) GetActiveScene

GetActiveScene().buildIndex);//得到当前激活的场景
Unity3D_(API)场景切换SceneManager

游戏管理者 GamaManager

                if (Vector3.Distance(transform.position, startPoint.position) < 0.05f)//也是差不多得了
