LuaFramework案例_01

001.在C#代码中,直接 写 Lua代码

 void Awake()
    {
        LuaState lua = new LuaState();
        lua.Start();
        string luaScriptContent = @"print('在C#代码中,直接 写 Lua代码,start lua studio --> tolua');";      
        lua.DoString(luaScriptContent,"SudioHello.cs");
        lua.CheckTop();
        lua.Dispose();
        lua = null;
    }

002.读取外部文件,require一次,dofile可多次

//展示searchpath使用,require 与 dofile区别     
//lua.DoFile("StudioScriptsFromFile.lua"); //dofile,要写文件后缀,直接执行这个代码，而且多次执行，每次触发就会被调用。
//lua.Require ("StudioScriptsFromFile"); //require加载只执行一次，如果加载过不会再调用。
public class StudioScriptsFromFile : MonoBehaviour
{
    LuaState lua = null;
    private string strLog = "";   
    void Start()
    {
        Application.logMessageReceived += Application_logMessageReceived;
        lua = new LuaState();
        lua.Start();
        //绝对路径
        string fullPath = Application.dataPath + @"\LuaFramework\ToLua\Examples\02_ScriptsFromFile";
        lua.AddSearchPath(fullPath);//增加路径
    }

    /// <summary>
    /// 接收log信息
    /// </summary>
    void Application_logMessageReceived(string condition, string stackTrace, LogType type)
    {
        strLog += condition;
        strLog += "\r\n";
    }

    void OnGUI()
    {
        GUI.Label(new Rect(0, 0, 1000, 100), strLog);
        if (GUI.Button(new Rect(0, 110, 100, 150), "DoFile"))
        {
            strLog = "";
            lua.DoFile("StudioScriptsFromFile.lua");
        }
        else if (GUI.Button(new Rect(230, 100, 100, 100), "Require"))
        {
            strLog = "";
            lua.Require("StudioScriptsFromFile");
        }
        lua.Collect();
        lua.CheckTop();
    }

    void OnApplicationQuit()
    {
        lua.Dispose();
        lua = null;
        Application.logMessageReceived -= Application_logMessageReceived;
    }
}

03.使用lua的返回值 LuaState.Invoke比较直接

/// <summary>
/// 使用lua的返回值
/// </summary>
public class StudioCallLuaFunction : MonoBehaviour
{
    private string luaScriptContent = @"
function luaFunction(num)
print('函数luaFunction--加1');
return num+1;
end
   test={};
test.luaFunction=luaFunction
";
    LuaFunction luaFunc = null;
    LuaState lua = null;
    string tips = null;
    void Start()
    {
        Application.logMessageReceived += Application_logMessageReceived;
        new LuaResLoader();
        lua = new LuaState();
        lua.Start();
        DelegateFactory.Init();
        lua.DoString(luaScriptContent);
        luaFunc = lua.GetFunction("test.luaFunction");

        if (luaFunc != null)
        {
            int num = luaFunc.Invoke<int, int>(123456);      //第一个int是传入值,最后一个int是返回值 
            Debugger.Log("返回值,用 luaFunc.Invoke 调用----第一个int是传入值,第二个int是返回值 -->:" + num);

            num = callFunc();
            Debugger.Log("\r\n 自己的写的回调 ,然而跟invoke很相同-->:" + num);

            Func<int, int> Func = luaFunc.ToDelegate<Func<int, int>>();
            num = Func(123456);
            Debugger.Log("\r\n 使用委托:" + num);

            num = lua.Invoke<int, int>("test.luaFunction", 123456, true);
            Debugger.Log("\r\n直接使用LuaState.Invoke ,中间少了LuaFunction这个类 -->:" + num);
        }
        lua.CheckTop();
        Debugger.Log("\r\n 统上所言,使用LuaState.Invoke是最直观的");
    }
    //public R1 Invoke<T1, R1>(T1 arg1)
    //{
    //    BeginPCall();
    //    PushGeneric(arg1);
    //    PCall();
    //    R1 ret1 = CheckValue<R1>();
    //    EndPCall();
    //    return ret1;
    //}
    private int callFunc()      
    {//这个回调,跟Invoke方法基本相同
        luaFunc.BeginPCall();
        luaFunc.Push(123456);
        luaFunc.PCall();
        int num = (int)luaFunc.CheckNumber();
        luaFunc.EndPCall();
        return num;
    }
    void Application_logMessageReceived(string condition, string stackTrace, LogType type)
    {
        tips += condition;
        tips += "\r\n";
    }
    void OnGUI() {
        GUI.Label(new Rect(0,10,600,800),tips);
    }
    void OnDestroy() {
        if (luaFunc!=null)
        {
            luaFunc.Dispose();
            luaFunc = null;
        }
        lua.Dispose();
        lua = null;
        Application.logMessageReceived -= Application_logMessageReceived;
    }
}
