调用Function

FunctionLua.lua.txt

    function NoParam()
        print('LuaFunction NoParam')
    end

    function HaveParam(a, b)
        print('LuaFunction HaveParam : ', 'a: ', a, 'b: ', b)
    end

    function HaveMultiParam(...)
        print(...)
    end

    function ReturnString()
        print('LuaFunction ReturnString')
        return "i am the return string!"
    end

    function ReturnFunction()
        print('LuaFunction ReturnFunction')
        return NoParam
    end

    function ReturnMultiValue()
        print("LuaFunction ReturnMultiValue")
        return true, "ReturnMultiValue", 1, "num"
    end

一、映射到Delegate

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    using XLua;

            LuaEnv luaEnv = new LuaEnv();

            void Start () {

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

                NoParam();
                HaveParam();
                HaveMultiParam();
                HaveReturnString();
                HaveReturnFunction();
                HaveMultiReturn();
            }

            void Update () {

            }

            private void OnDestroy()

            #region 无参数

            #endregion

            #region 有任意个参数

            public delegate void HaveMultiParamDel(params int[] nums);
            void HaveMultiParam()

            #endregion

            #region 有字符串返回值
            [CSharpCallLua]
            public delegate string HaveReturnStringDel();
            void HaveReturnString()

                string r = del();
                Debug.Log("GetResturn :" + r);
            }
            #endregion

            #region 有方法返回值
            [CSharpCallLua]
            public delegate Action HaveReturnFunctionDel();

                Action result = del();
                result();
            }
            #endregion

            #region 多返回值
            // 多返回值的，返回值从左到右的依次映射，返回值，out参数或ref参数 。。。
            [CSharpCallLua]
            public delegate bool HaveMultiReturnDel(ref string a, out int b);

            void HaveMultiReturn()

二、映射到LuaFunction

                NoParam();

                HaveReturnString();
                HaveReturnFunction();
                HaveMultiReturn();
            }

            void Update () {

            }

            private void OnDestroy()
            {
                luaEnv.Dispose();
            }

            #region 无参数
            void NoParam()
            {
                LuaFunction del = luaEnv.Global.Get<LuaFunction>("NoParam");
                del.Call();
            }
            #endregion

            #region 有参数
            void HaveParam()
            {
                LuaFunction del = luaEnv.Global.Get<LuaFunction>("HaveParam");
                del.Call(10, 20);
            }
            #endregion

            #region 有返回值是字符串
            void HaveReturnString()
            {
                LuaFunction del = luaEnv.Global.Get<LuaFunction>("ReturnString");
                object[] r = del.Call();
                Debug.Log(r[0]);
            }
            #endregion

            #region 有返回值是方法
            void HaveReturnFunction()
            {
                LuaFunction del = luaEnv.Global.Get<LuaFunction>("ReturnFunction");
                object[] result = del.Call();
                ((LuaFunction)result[0]).Call();
            }
            #endregion

            #region 多返回值

            }
            #endregion
        }
    }
