简单的Unity toLua框架

设计思路:
全局只创建一个LuaState, 所有lua类都用Table实现
主要文件:

LuaScriptManager.cs	//lua脚本管理,创建LuaState
LuaBehaviour.cs		//让lua控制游戏对象的中间Component
class.lua			//所有lua脚本的基类

LuaScriptManager.cs

public class LuaScriptManager {
    private static LuaState _luaState;
    public static LuaState luaState {
        get
        {
            if (null == _luaState)
            {
                Init();
            }
            return _luaState;
        }
    }

    public static void Init()
    {
        new LuaResLoader();
        _luaState = new LuaState();
        _luaState.LogGC = true;
        _luaState.Start();
        LuaBinder.Bind(_luaState);
		DelegateFactory.Init();
        //添加搜索路径
        _luaState.AddSearchPath(Application.dataPath + "\\Resources/Lua");
        _luaState.AddSearchPath(Application.dataPath + "\\Resources/LuaScripts");
        _luaState.AddSearchPath(Application.dataPath + "\\Resources/LuaScripts/UIModule");
    }

    public static object RunLuaFile(string filePath)
    {
        return luaState.DoFile(filePath);
    }

    public static object RunLuaString(string luaStr)
    {
        return luaState.DoString(luaStr);
    }
}
