销毁所有预制克隆无法正常工作的实例

Question

我正在编写一个重启功能，我想删除属于某个面板的所有预制件的实例。此代码将新输入字段添加到父

private void ShowInputField(){

    GameObject inputFieldGameObject = inputFieldObjectPool.GetObject();

    //reset pool since it may have been disabled by the DeActivatePreviousInputFields function
    InputField inputField = inputFieldGameObject.GetComponent<InputField>();
    inputField.Select ();
    inputField.ActivateInputField ();
    inputField.interactable = true;
    inputField.readOnly = false;

    //make this the previous inputs
    previousInputs = inputFieldGameObject;

    //assign the prefab to its parent panel
    inputFieldGameObject.transform.SetParent (inputFieldParent);
    inputFieldGameObject.transform.localScale = Vector3.one;
    Canvas.ForceUpdateCanvases ();

    //make scroll bar always show the last added input field
    GameObject.Find ("ScrollView").GetComponent<ScrollRect> ().horizontalNormalizedPosition = 1;

}

下图显示了重启前的样子

重启的代码，它会销毁预制件的所有实例并再次添加一个，如下所示。

void RestartGame(){
    //gets all elements of the parent 
    InputField [] childElements = letterPanel.GetComponentsInChildren<InputField> ();
    Debug.Log (childElements.Count());
    foreach (var item in childElements) {
        Destroy (item);
    }
    ShowInputField()
}

这应该会破坏预制件的所有实例，但它不会使它们只能通过下面的图像显示它来编辑

我该如何解决这个问题？提前谢谢你......

Answer 1

您试图从列举的列表中销毁当前项目，但这是一个无法销毁的输入字段。而是通过引用它属于并销毁它的游戏对象，删除输入字段。

我做了这个并且有效

void RestartGame(){
    //gets all elements of the parent 
    InputField [] childElements = letterPanel.GetComponentsInChildren<InputField> ();
    Debug.Log (childElements.Count());
    foreach (vInputField item in childElements) {
        if(item.name.Contains("InputField")){
            Destroy (item.gameObject);
        }
    }
    ShowInputField()
}
