Question

我正在使用协同程序功能，但我单击下一步按钮时应创建新对象，以销毁旧对象

public class SceneChanger: MonoBehaviour
{
    private List<string> sceneHistory = new List<string>();  //running history of scenes
    public GameObject[] charset; //The last string in the list is always the current scene running
    public GameObject changer;
    public int chartotalnum = 3;
    public float Timer;
    public int rand;
    public Button Next;
    public GameObject go;

    void Start()
    {
        GameObject go = Instantiate(charset[rand], new Vector3(0, 0, 0), Quaternion.identity) as GameObject;
        Destroy(go, 5f);
        rand++;
        //StartCoroutine(Spawn());
        Button btn = Next.GetComponent<Button>();
        btn.onClick.AddListener(ClickedNext);
        //DontDestroyOnLoad(this.gameObject);  //Allow this object to persist between scene changes
    }
    
    void Update()
    {
      
    }
    
    IEnumerator Spawn()
    {
        yield return new WaitForSeconds(5f);
        GameObject go = Instantiate(charset[rand], new Vector3(0, 0, 0), Quaternion.identity) as GameObject;
        Debug.Log("test");
        rand++;
        Destroy(go, 5f);
    }
    
    public void ClickedNext()
    {
        StopCoroutine(Spawn());
        Destroy(go);
        go = Instantiate(charset[rand], new Vector3(0, 0, 0), Quaternion.identity) as GameObject;
        rand++;
        Destroy(go, 5f);
        
        Debug.Log("clicked");
        StartCoroutine(Spawn());
    }
}

Answer 1

问题在于，在Start和Spawn中您都使用

GameObject go = Instantiate(charset[rand], new Vector3(0, 0, 0), Quaternion.identity) as GameObject;

从而创建一个名为go的局部变量，该变量将隐藏您现有的类字段go。

它必须是

go = Instantiate(charset[rand], new Vector3(0, 0, 0), Quaternion.identity);

在Start和Spawn中使用现有字段代替新的局部变量。

Answer 2

我从以下位置删除了gameObject go =实例化（charset [rand]，将新的Vector3（0，0，0），Quaternion.identity）作为GameObject;

调用新对象时立即销毁游戏对象
