单击一个按钮时实例化弹出窗口 [英] instantiate a Popup when click a button in unity

问题描述

我想在按下按钮时显示弹出窗口.

I want to show popup when press the button.

但是现在看起来像这样

我已经看过许多关于如何在按下按钮时弹出窗口的教程.

I have viewed many tutorials about how to make a popup when press the button.

但是它们全都是通过脚本弹出的，而不是实例化预制件.

But they all make the popup by script,not instantiate the prefab.

我不确定是否可以按照我的意愿实例化预制件，否则这不是一个好主意.

I'm not sure if I can instantiate the prefab as I hope or it's not a good idea.

这是我的代码

using UnityEngine;
using System.Collections;
using UnityEngine.EventSystems;

public class Purchase : MonoBehaviour,IPointerClickHandler
{
    public GameObject purchasePanel;
    public GameObject panelPosition;

public void OnPointerClick (PointerEventData eventData)
    {

        GameObject instantiatedPurchase = Instantiate(purchasePanel, panelPosition.transform.position,panelPosition.transform.rotation) as GameObject;  
    instantiatedPurchase.transform.SetParent(panelPosition.transform);
}

}

推荐答案

您可能会使用Unity.UI，而仅使用面板.

You would probably use Unity.UI, and just use a panel.

这非常容易(1)单击添加画布"(2)单击添加面板".

It is very easy (1) click "add canvas" (2) click "add panel".

只需

 .SetActive

来自您的代码.享受！如您所见，这很简单:

from your code. Enjoy! As you can see it's this easy:

尝试在编辑器中打开和关闭它，并在Inspector上进行切换.在代码中只是..

Try turning it on and off in the Editor with that toggle on Inspector. In code it's just..

   public GameObject popupPanel;
   ...
   popupPanel.SetActive(false);  or...
   popupPanel.SetActive(true);
