QuickCocos C++绑定Lua后编译出错

Cocos2d-x Lua
#1

我在quick\lib\extra 增加了一个测试类：
*
*
//cpp
*#include “MyExt.h”

int MyExt::Adder(int a, int b)
{
return a + b;
}

//header
#ifndef MY_EXT_H
#define MY_EXT_H

class MyExt
{
public:
static int Adder(int a, int b);
};

#endif

然后在cocos2dx_extra_luabinding.tolua
加了头文件和pkg代码
$#include “myExt/MyExt.h”

class MyExt
{
static int Adder(int a, int b);
};

build.bat编译也通过了，但是在重编Player3的时候出错了……

是不是重编
**cocos2dx_extra_luabinding.tolua的时候把原来的某些代码抹掉了呢？
**求助应该如何解决。

#2

第一个问题已经解决，果然是build.bat的时候，把几个宏给抹掉了，我用对比工具把那几个宏merge过去就能编译过了。现在问题来了，学挖掘机……不对

问题是，我把framework_precompile.zip重新编了一遍，但是没有在里面发现我的,MyExt包。
如何在脚本里使用我的MyExt，默认extra里的东西会被加载到那个包里面？需要加载哪个包么？

#3

绑定好脚本里就可以直接用了

#4

我试了一下，直接写
local reault = MyExt.Adder( 1,2 )

会报错提示 MyExt是nil。

和Quick3.2的文件结构有关系吗，是否需要把某些库重新设置一下？

#5

生成的绑定文件加到工程里了没有？

#6

我是直接加到cocos2dx_extra_luabinding.tolua里面然后用build.bat生成。

生成的是cocos2dx_extra_luabinding.cpp,默认就是在工程里面的。

参考网上的教程做，说是加到那个文件就可以。

#7

绑定代码是指这些么？

这代码里绑定的是cc.MyExt

#9

谢谢大神。

没找到的原因有两个，一个是你说的使用cc.MyExt访问，还有一个问题就是我的IDE默认去 player/ProjWin32/bin/里面找Player3和对应DLL。我把Debug里面的所有文件拷贝到Bin文件夹下面，然后按照cc.MyExt的方式访问，终于能使用了。

#10

楼主可以写一个简明教程么，现在就没有一个靠谱的，感觉现在你至少是弄好了

#11

:8:
我也也是按照网上的教程弄的，
http://blog.csdn.net/w00w12l/article/details/40430379
最后不能访问，报nil错误，找来好久问题，原来前面要加 cc.，终于可以用了

噢 苍天啊！感谢大神
