以编程方式统一处理ngui的按钮事件 [英] handle ngui's button event programmatically in unity

问题描述

我正在从Unity的UI转移到NGUI.

I'm transferring from Unity's UI to NGUI.

以前，我可以使用以下脚本将侦听器添加到按钮:

Formerly, I could add listeners to button with following scripts:

button.GetComponentInChildren<Button>().onClick.AddListener(() =>
{
    //codes that could be triggered by click the button. 
});

但是当更改为NGUI时，我无法通过以下方式使其工作:

But when changing to NGUI, I can't make it work by:

EventDelegate.Set(go.GetComponent<UIButton>().onClick, OnButtonClickActive);

private void OnButtonClickActive()
{
   Debug.Log("active button clicked");
}

推荐答案

最后，我通过使用以下脚本将自定义事件添加到 OnClick (使用 UIEventListener ):

Finally, I made this work by adding a custom event to OnClick with the following script (using UIEventListener):

UIEventListener.Get(go).onClick += OnButtonClickActive;

事件处理程序的定义如下:

And the event handler is defined as follows:

private void OnButtonClickActive(GameObject go)
    {
        int level;
        int.TryParse(go.GetComponentInChildren<UILabel>().text, out level);
        Debug.Log(level + "active button clicked");
        ApplicationModel.CurrentLevel = ApplicationModel.Levels[level - 1];
        SceneManager.LoadScene("PlayScene");
    }

请注意，通过游戏对象中的 UILable 组件传递参数(级别信息)可能有点愚蠢.如果还有其他更优雅的方法，请告诉我.

Note that, it might be a little bit silly to pass the parameter (level info) with the UILable component in the gameobject. If there is other more elegant way, please let me know.
