本文介绍了我用LuaBind在C ++中用Lua代码包装什么代码？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我终于得到LuaBind配置为与我的C + +项目。我最近发现，Tiled地图编辑器有一个选项将文件导出为.lua，所以我想试试看。下面的代码是否可以用于我的C ++ RPG项目？

解决方案
警告：我的回答可能是nooby
首先，删除属于以下内容的 return 和{}回报。
现在把它放到你的程序可以找到的地方。
现在来到luabind部分（luabind对这种工作不是真正必要的，但我会使用它，因为它是一个很好的做法）。
让我们看看你的主程序使用这些值叫做 stage
，调用 load 。
从头开始：
externC
{
#include< lua.h>
#include< lualib.h>
#include< lauxlib.h>
}
#include.\luabind\luabind.hpp
#include< iostream>
class Stage
{
public：
Stage（）;
Stage（string stage_name）;
//阶段用于运行的方法
static void _load（< a input of input
或任何你希望传递信息的方式>，
intptr_t stage） ; / * static for luabind intptr_t设计为
以保持int形式的指针。* /
void load（< a input of input或者你想要传递信息的任何方式>）;
〜Stage（）;
private：
//很多你想要的值。
}
在cpp文件中，开始游戏：
void _load（<输入表
或任何你想要传输的方式信息>表，
intptr_t stage）
{
Stage * stage =（Stage *）stg; // intptr_t back to pointer
stage-> load（table）;
}
void Stage：load（< a input of input
或任何你想传递信息的表>表）
{
< load infos into your variable>
}
Stage（string stage_name）
{
intptr_t stage =（intptr_t）* this;
//创建一个新的lua状态
lua_State * myLuaState = luaL_newstate（）;
//将LuaBind连接到这个lua状态
luabind :: open（myLuaState）;
luaL_openlibs（myLuaState）;
luabind :: module（myLuaState）[
luabind :: def（load，& _load）
];
luabind :: globals（myLuaState）[stage] = stage; //给指针指向lua
stringstream fileadd< < candidate address here> ;;
lual_dofile（myLuaState，fileadd）;
lua_close（myLuaState）; /我们不需要lua /
< start your game>
}
lua示例：
<您的原始档案无返回>
<将它放入表或某事>
- load是在您的阶段启动后的可调用文件cpp
- stage是传递给lua的指针
load（< table of information> stage）
这取决于你如何传递变量，但我认为这个方法应该可以正常工作， / p>
I finally got LuaBind configured to work with my C++ project. I recently found out that the Tiled map editor has an option to export the files as a .lua, so I wanted to try it out. What code would I wrap around the pasted code below to have it work with my C++ RPG project?

Warning: My answer might be nooby since I'm the kind prefer more work and less complicates.
first, remove the return and {} that belong to the return.now put it to a place that your program can find it.
now come to the luabind part(luabind is not really necessary for this kind of job, but i will use it since it's a good practice for you).
let's see your main program that uses these values is called stageand there is a loader method called load.Start with the header:
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.
}
And in the cpp file, you well want load in the start of the game:
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>
}
Example of lua:
<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)
It's up to you how to pass the variables, but I think this method should works fine, just lots works?
