重Lua官網下載最新的Lua5.3.2解壓後把src檔案下的所有檔案（Lua.c,Luac.c除外）複製到專案的目錄下，並新增到專案中，

建立一個Lua指令碼檔案

--region *.lua  
--Date  
--此檔案由[BabeLua]外掛自動生成  

print("lua script func.lua have been load ") 
avg, sum = average(10, 20, 30, 40, 50)
print("The average is ", avg)
print("The sum is ", sum)

function add(x,y)
    return
 
 x+y+x*y
end

--endregion 

C++檔案如下

#include <iostream>
#include <stdio.h>  

extern "C" {
//#include "lprefix.h"
#include "lua.h"
#include "lauxlib.h"
#include "lualib.h"
}

using namespace std;

lua_State* L;

static int average(lua_State *L)
{
    //返回棧中元素的個數  
    int n = lua_gettop(L);
    double
 
 sum = 0;
    int i;
    for (i = 1; i <= n; i++)
    {
        if (!lua_isnumber(L, i))
        {
            lua_pushstring(L, "Incorrect argument to 'average'");
            lua_error(L);
        }
        sum += lua_tonumber(L, i);
    }
    /* push the average */
    lua_pushnumber(L, sum / n);
    /* push the sum */
 

    lua_pushnumber(L, sum);

    /* return the number of results */
    return 2;
}

void main()
{
    //cout << "Hello CML" << endl;

    /* 初始化 Lua */
    L = luaL_newstate();

    /* 載入Lua基本庫 */
    luaL_openlibs(L);

    /* register our function */
    lua_register(L, "average", average);

    /* 執行指令碼 */
    luaL_dofile(L, "e://lua1.lua");

    lua_getglobal(L, "avg");
    int avg = lua_tointeger(L, -1);
    lua_pop(L, 1);
    lua_getglobal(L, "sum");
    int sum = lua_tointeger(L, -1);

    lua_getglobal(L, "add");
    lua_pushinteger(L, 10);
    lua_pushinteger(L, 20);
    lua_pcall(L, 2, 1, 0);
    printf("lua add function return val is %d \n", lua_tointeger(L, -1));

    /* 清除Lua */
    lua_close(L);

    /* 暫停 */
    printf("Press enter to exit…");
    getchar();
}
