XLua C#訪問Lua中的全局function

通過Action委託訪問

CSharpCallLua.lua.txt

function add(a,b)

    print(a+b)

end

CSharpCallLua.cs

using UnityEngine;

using XLua;

using System.Collections.Generic;

using System;

 

public class CSharpCallLua : MonoBehaviour {

    void Start () {

        LuaEnv luaEnv = new LuaEnv();

        luaEnv.DoString("require 'CSharpCallLua'");

 

        //訪問Lua中的全局函數

        Action act1 = luaEnv.Global.Get<Action>("add");

        act1(10,20);

        act1 = null;//必須置空，否則釋放虛擬機時會報錯

 

        luaEnv.Dispose();

    }       

}

通過自定義委託訪問

CSharpCallLua.lua.txt

function add(a,b)

    print(a+b)

    return a+b,a,b

end

CSharpCallLua.cs

using UnityEngine;

using XLua;

using System.Collections.Generic;

using System;

 

public class CSharpCallLua : MonoBehaviour {

    void Start () {

        LuaEnv luaEnv = new LuaEnv();

        luaEnv.DoString("require 'CSharpCallLua'");

 

        //映射到Delegate

        Add add = luaEnv.Global.Get<Add>("add");

        int resa = 0;

        int resb = 0;

        int res = add(10, 20, out resa, out resb);

        print(res); //30

        print(resa); //10

        print(resb); //20

        add = null;

 

        luaEnv.Dispose();

    }

  

    [CSharpCallLua]

    delegate int Add(int a, int b,out int resa,out int resb); //自定義委託

    //     第1個返回值                 第2個返回值   第3個返回值   

}

通過LuaFunction訪問Lua中的全局函數（性能慢）

CSharpCallLua.lua.txt

function add(a,b)

    print(a+b)

    return a+b,a,b

end

CSharpCallLua.cs

using UnityEngine;

using XLua;

using System.Collections.Generic;

using System;

 

public class CSharpCallLua : MonoBehaviour {

    void Start () {

        LuaEnv luaEnv = new LuaEnv();

        luaEnv.DoString("require 'CSharpCallLua'");

 

        //映射到LuaFunction

        LuaFunction func = luaEnv.Global.Get<LuaFunction>("add");

        object[] os= func.Call(1, 2);//os是所有的返回值

        foreach (object o in os)

        {

            print(o);

        }

 

        luaEnv.Dispose();
