我终于将 LuaBind 配置为与我的 C++ 项目一起使用。我最近发现 Tiled 地图编辑器可以选择将文件导出为 .lua，所以我想尝试一下。我将围绕下面粘贴的代码包装什么代码以使其与我的 C++ RPG 项目一起使用？

return {
  version = "1.1",
  luaversion = "5.1",
  orientation = "orthogonal",
  width = 24,
  height = 20,
  tilewidth = 16,
  tileheight = 16,
  properties = {},
  tilesets = {
    {
      name = "PALLET TOWN",
      firstgid = 1,
      tilewidth = 16,
      tileheight = 16,
      spacing = 0,
      margin = 0,
      image = "PALLET TOWN.bmp",
      imagewidth = 384,
      imageheight = 320,
      properties = {},
      tiles = {}
    }
  },
  layers = {
    {
      type = "tilelayer",
      name = "Tile Layer 1",
      x = 0,
      y = 0,
      width = 24,
      height = 20,
      visible = true,
      opacity = 1,
      properties = {},
      encoding = "lua",
      data = {

警告：我的回答可能不太好，因为我喜欢更多的工作和更少的复杂性。

首先，删除return属于返回的和{}。现在把它放到你的程序可以找到的地方。

现在来到 luabind 部分（对于这种工作来说，luabind 并不是真正必要的，但我会使用它，因为它对你来说是一个很好的做法）。

让我们看看使用这些值的主程序被调用stage ，并且有一个名为load. 从标题开始： 

extern "C"
{
    #include <lua.h>
    #include <lualib.h>
    #include <lauxlib.h>
}
#include ".\luabind\luabind.hpp"
#include <iostream>

class Stage
{
    public:
        Stage();
        Stage(string stage_name);
        // the methods that stage use to run
        static void _load(<a table of input
           or whatever the way you want to transfer the information>,
                          intptr_t stage);/* static for luabind intptr_t is designed 
              to hold pointer in int form.*/
        void load(<a table of input or whatever the way you want to transfer the information>);
        ~Stage();

    private:
        //lot of values that you want.

}

在 cpp 文件中，您很希望在游戏开始时加载：

    void _load(<a table of input
       or whatever the way you want to transfer the information> table,
       intptr_t stage)
    {
        Stage* stage = (Stage*)stg; // intptr_t back to pointer
        stage->load(table);
    }

    void Stage:load(<a table of input
       or whatever the way you want to transfer the information> table)
    {
        <load infos into your variable>
    }

    Stage(string stage_name)
    {

        intptr_t stage = (intptr_t)*this;
        // Create a new lua state
        lua_State *myLuaState = luaL_newstate();

        // Connect LuaBind to this lua state
        luabind::open(myLuaState);
        luaL_openlibs(myLuaState);

        luabind::module(myLuaState)[
        luabind::def("load", &_load) 
        ];

        luabind::globals(myLuaState)["stage"] = stage;// give the pointer to lua

        stringstream fileadd << <candidate address here>;
        lual_dofile(myLuaState, fileadd);
        lua_close(myLuaState);/we don't need lua anymore/

        <start your game>
     }

lua 示例：

    <your origin file without return>
    <put it into a table or something>
    -- load is a callable file after it's launched with your stage cpp 
    -- stage is the pointer that passed to lua
    load(<table of information>, stage)

如何传递变量取决于您，但我认为这种方法应该可以正常工作，只是很多工作？
