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
