尋路功能：

public class MOVE : MonoBehaviour {

    //玩家
    public GameObject player;
    //敵人
    public GameObject go;
    void Start () {
    
        go = GameObject.Find("Cube");
        player = this.gameObject;
        //查找標(biāo)簽為Player的物體并返回
        player = GameObject.FindGameObjectWithTag("Player");
        
       
        
    }

    void Update () {
        //敵人面向玩家
        go.transform.LookAt(player.transform);
        //敵人向玩家方向移動(dòng)
        go.transform.Translate(go.transform.forward *-1f* Time.deltaTime * 5f);
    }
}
