FairyGUI学习记录

创建UI

使用FGUI创建UI界面的时候，可以选择创建用UIPackage创建组件，然后GRoot.inst添加到Stage里，层级根据子对象的排列顺序显示；
也可以选择创建GameObject添加UIPanel脚本，在UIPanel里赋值包名和组件名显示UI界面，但是需要手动设置层级，不能直接使用UIPanel的sortingOrder属性设置层级，需要使用SetSortingOrder(1, true)设置，第一个参数是层级，第二个设置为true才能使用层级，不然会重复显示UI；

UI管理

我的项目里使用Lua进行管理，设置FairyGUIManager = {}；
Lua表可以根据下标访问，表结构为FairyGUIManager = { [1] = { componentName = “UI名” ， panel = panel （此处panel是添加的UIpanel脚本，方便后续对UI的管理，可以直接使用gameObject访问UI的游戏对象，也可以使用panel.ui访问FairyGUI的ui组件 ） } }

创建UIPanel

设置变量UISortingLayer = 1；
table.insert(FairyGUIManager, { componentName = “UI名” , panel = panel })
panel:SetSortingOrder(UISortingLayer, true);
UISortingLayer = UISortingLayer + 1 ;

卸载UIPanel

for i = #FairyGUIManager , 1, -1 do
if FairyGUIManager[i].componentName = “UI名” then
UnityEngine.GameObject.Destroy(FairyGUIManager[i].panel.gameObject);
table.remove(FairyGUIManager[i]);
end
end
UISortingLayer = UISortingLayer - 1;

Lua表下标自动排列，新界面的层级会放置到最高一个；

FairyGUIManager.lua代码

我这里使用UIPanel方式创建，若项目弹出界面可以使用Popup的方式创建UI；

ToLua使用

functions.lua 里添加一个方法

--- multiphandler方法，可以输入更多变量，用于FGUI里的按钮Add方法(如果你使用的是ToLua，在Scripting Define Symbols里加上 FAIRYGUI_TOLUA。XLUA则不需要。)
--- 例如：self.view.onClick:Add(multiphandler(self, self.BtnClick, self.view.name));
--- 把self.view.name 当作参数传到self.BtnClick方法里；
--- 使用：
--function Test:BtnClick( ... )
--    local val = select(1, ... );
--    local data = val[1];
--    print("第一个参数是" .. data);
--end

function multiphandler( ... )
    local val = { ... };
    local val2 = {select(3, ... )};
    return function(...)
        val[2](val[1], val2);
    end
end
