Unity3D实现打砖块游戏

public GameObject buttle;//用于获得子弹对象
public float speed = 20F;
    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {
        //当鼠标按下左键时触发
        if (Input.GetMouseButtonDown(0))
        {
            //创建子弹对象
           GameObject gb = GameObject.Instantiate(buttle,transform.position,transform.rotation);
           //创建刚体对象
           Rigidbody rg = gb.GetComponent<Rigidbody>();
           //设置子弹初始速度
           rg.velocity = transform.forward * speed;
        }
    }

public class Movement : MonoBehaviour {
    public float speed = 5F;
    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {
        float h = Input.GetAxis("Horizontal"); //控制水平移动
        float v = Input.GetAxis("Vertical");//控制垂直移动

        //设置摄像机位置
        transform.Translate(new Vector3(h, v, 0) * Time.deltaTime * speed);
