4.UI事件

案例:Assets/Scripts/Example/3.UIFrame/UIEvent/UIEventExample.unity

1).UI脚本注册事件

UIMainEvent脚本RegisterUIEvent函数 :

 protected override void RegisterUIEvent()
    {
        trans.onClick.AddListener(()=>
        {
            UIManager.Instance.OpenUI<UIChildEvent>((int)eventUITag.UIChildEvent, null, panelLayer: PanelLayer.Load, isClear: true);
        });
        RegisterEvent((int)eventID.changeMainColor, ChangeColor);
    }
//事件响应
 private void ChangeColor(int key,MsgInfo param)
    {
        if (param != null && param.DataList.Count > 0)
        {
            Color color = (Color)param.DataList[0];
            bg.color = color;
        }
    }

2).发送UI消息

这个案例时打开子面板然后点击子面板按钮改变父面板背景颜色
子面板UIChildEvent :

 protected override void RegisterUIEvent()
    {
        button.onClick.AddListener(() =>
        {
            SendMsg((int)eventID.changeMainColor,new MsgInfo(Color.red));
        });
    }
