C++将结构体传给lua .

C++代码

void CProject1Dlg::OnBnClickedButton2()
{
// 打开换为 luaL_newstate
lua_State *L = luaL_newstate() ; /* 打开 Lua */
luaL_openlibs(L); /* 加载 .lib 文件 */

// 加载脚本文件，需要放在程序目录
luaL_loadfile( L, "test.lua" );
lua_resume( L, 0 , 0);

typedef struct
  {
int a;
CString strTest;

struct test
    {
int b;
    }c;
  }A;

A a;
a.a = 10;
a.c.b = 322;
a.strTest = _T("yes");
lua_getglobal(L,"structTest");  

lua_newtable(L);
lua_pushinteger(L,a.a);
lua_setfield(L,-2,"a");
lua_newtable(L);
lua_pushinteger(L,a.c.b);
lua_setfield(L,-2,"b");
lua_setfield(L,-2,"c");
lua_pushstring(L,CStringA(a.strTest).GetString());
lua_setfield(L,-2,"strTest");

lua_pcall(L,1,1,NULL);  // 

// 输出计算结果
CString c = CString(lua_tostring(L,-1)) ;
lua_pop(L,1) ;      // 清除堆栈 清除计算结果

// 调用结束
lua_close(L);

MessageBox(c);
}

Lua代码

function structTest(a)

return string.format("做个测试 \r\n a.a = %d \n a.b = %d \n a.strTest = %s",
a.a,a.c.b,a.strTest);

end
