cocos的入门项目已经编译通过，仅供参考。。 已经预编译可加快编译速度

如qsort 等函数需要函数指针才能回调 用此函数库可以将成员函数指针转为普通函数指针 测试代码如下 #include <stdio.h> #include <algorithm> #include <vector> #include <string> #include <iostream> #include <math.h> using cmpfunc = int(__cdecl*)(const void*, const void*); using DebugArrayFunc = void(__stdcall *)(std::string &out;); #include "thunk.h" class MySort { public: int Rule; MySort(int a):Rule(a){} // 回调函数 template<typename T> int __cdecl sort(const void* a, const void* b); }; class Test { public: std::vector<int> mm; void Sort(int (*comp)(const void *,const void *)) { return qsort(mm._Myfirst,mm.size(),sizeof(int),comp); } void Entry(DebugArrayFunc func) { std::string string; cmpfunc comp; TemplateThunk athunk; // 正序 comp = (cmpfunc)athunk.GetCall(&MySort;::sort<int>, &MySort;(0)); Sort(comp); func(string); std::cout << string << std::endl; // 逆序 comp = (cmpfunc)athunk.GetCall(&MySort;::sort<int>, &MySort;(1)); Sort(comp); func(string); std::cout << string << std::endl; } }; class CallBack { public: std::vector<int> *pthis; CallBack(std::vector<int> *ff):pthis(ff){} void __stdcall DebugArray(std::string &out;) { char buff[100]; char *aa = buff; for each (auto a in *pthis) { aa += sprintf(aa, "%d ", a); } out.assign(buff); } }; void main() { TemplateThunk athunk; Test tt; tt.mm = { 1, 3, 7, 8, 5, 6, 4, 2, 3, 10 }; tt.Entry(athunk.GetCall(&CallBack;::DebugArray,&CallBack;(&tt;.mm))); } template <typename T> int __cdecl MySort::sort(const void* a, const void* b) { return Rule ? *static_cast<const T*>(a)-*static_cast<const T*>(b) : *static_cast<const T*>(b)-*static_cast<const T*>(a); }

lua反编译工具包括lua 5.1 与 lua 5.2 包括lua.exe luac.exe luadec.exe 等 可以用此工具加密lua为luac 也可以解密luac为lua

1代码中此处可能需要修改vcvarsall.bat文件位置 call "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat" amd64 解密文件所在路径尽量不要出现中文 2只有用luac加密的资源才能解密 3需要vs环境自带java环境
