tolua 学习笔记 资源加载、数据读取

对list.lua不熟悉的可以参考http://blog.csdn.net/Jason_520/article/details/54238020
UI监听事件http://blog.csdn.net/jason_520/article/details/54233497

效果大概就是这样：

运行游戏，点击显示面板按钮，显示另一个面板，并且读取资源显示对应内容。

附上lua代码：

--TranScriptInfo.luaTranScriptInfo = {    id = "0",    areaName = "0",    scriptName = "0",    scriptIcon = "0",    scriptTable = "0",    scriptScene = "0"};TranScriptInfo.__index = TranScriptInfofunction TranScriptInfo:new(id,areaName,scriptName,scriptIcon,scriptTable,scriptScene)    local o = {};    setmetatable(o,self);    o.id = id;    o.areaName = areaName;    o.scriptName = scriptName;    o.scriptIcon = scriptIcon;    o.scriptTable = scriptTable;    o.scriptScene = scriptScene;    return o;end

做下两个预设

在LuaFramework/Examples创建文件夹Data，创建area.txt，内容如下：

区域ID,区域名字,副本名字,副本图标,副本所在表,副本场景id,areaName,scriptName,scriptIcon,scriptTable,scriptScene1,区域一,格林之森,c1,Data/battle_001,battle2,区域一,天空之城,c2,Data/battle_002,battle3,区域一,王之遗迹,c3,Data/battle_003,battle4,区域二,机械牛,d1,Data/battle_004,battle5,区域二,雪山,d2,Data/battle_005,battle6,区域二,天界,d3,Data/battle_006,battle

在ResourceManager.cs添加两个方法：

public void LoadSprite(string abName, string[] assetNames, LuaFunction func){    LoadAsset<Sprite>(abName, assetNames, null, func);}public void LoadTextAsset(string abName, string[] assetNames, LuaFunction func){    LoadAsset<TextAsset>(abName, assetNames, null, func);}

在packager.cs添加需要打成AB包的代码：

AddBuildMap("selectArea" + AppConst.ExtName, "*.prefab", "Assets/LuaFramework/Examples/Builds/SelectArea");AddBuildMap("selectTranScript" + AppConst.ExtName, "*.prefab", "Assets/LuaFramework/Examples/Builds/SelectTranScript");AddBuildMap("selectTranScript_asset" + AppConst.ExtName, "*.png", "Assets/LuaFramework/Examples/Textures/SelectTranScript");AddBuildMap("data" + AppConst.ExtName, "*.txt", "Assets/LuaFramework/Examples/Data");

这边还要提下，切记CustomSetting.cs中添加（其实是为了提醒我自己，整天忘记）：

_GT(typeof(Image)),_GT(typeof(Sprite)),_GT(typeof(Button)),_GT(typeof(TextAsset)),_GT(typeof(StringSplitOptions)),

在GameManager.cs中做这样修改。

大概整个思路是：
* 1 unity启动SelectAreaCtrl.lua，调用Awake函数，创建”_selectAreaPanel”面板，然后注册一些ui按钮事件。
* 2 点击显示面板按钮，调用SelectTranScriptCtrl.Open方法，此方法调用SelectTranScriptPanel.Awake方法，创建_selectTranScriptPanel面板，以及一些数据的初始化。
* 3 SelectTranScriptCtrl.GetInfo 加载area.txt文件内容，并且显示在ui上。

实现内容很简单，可是过程用lua来实现，感觉好乱，不过继续努力吧！！！

笔者也是刚刚接触LuaFramework，博文只是作为学习笔记与大家分享，希望能与大家共同进步。
