敵人關注玩家，輪轉

Question

我創造了跟隨玩家的敵人並旋轉。我的問題是，我的飛船模型旋轉是不同的，當我用Blender做它。
這是敵人如何遵守，如何船看起來像旋轉X：0 Y：0 Z：0

在攪拌機，一切都很好，沒有錯，旋轉等
這是敵人腳本

using UnityEngine; 
using System.Collections; 

public class Enemy : MonoBehaviour { 

     public static float health; 
     private float reloadTime; 

     public Rigidbody laser; 
     public GameObject explo; 
     public Transform playerShip; 

     // Use this for initialization 
     void Start() { 
       health = 20.0f; 
       reloadTime = 0.3f; 
     } 

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

       //transform.LookAt(playerShip.transform.position); 
       Quaternion rotation = Quaternion.LookRotation(playerShip.transform.position - this.transform.position); 
       transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * 2); 
       transform.Translate(Vector3.forward * 2 * Time.deltaTime); 

       reloadTime -= Time.deltaTime; 

       if(reloadTime <= 0f) 
       { 
         Rigidbody clone = Instantiate(laser, transform.position, transform.rotation) as Rigidbody; 
         clone.velocity = transform.TransformDirection(0, 0, 80); 
         Destroy(clone.gameObject, 3); 
         reloadTime = 0.3f; 
       } 

       if(health <= 0f) 
       { 
         GameObject exp = Instantiate(explo, transform.position, transform.rotation) as GameObject; 
         Destroy(this.gameObject); 
         Destroy(exp.gameObject, 1.5f); 
       } 
     } 
} 

這種旋轉會出現什麼問題？

如何更改此代碼中的旋轉因此X總是270？

  Quaternion rotation = Quaternion.LookRotation(playerShip.transform.position - this.transform.position); 
      transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * 2);

解決！只需要這樣做。： http://docs.unity3d.com/Manual/HOWTO-FixZAxisIsUp.html
