这以前写的代码
之前是玩家背包每个东西都是满的,副本掉落,会掉很多东西,因为玩家背包都满了,需要发送邮件,当时主程就要求这些东西作为一封邮件发出去
首先是获取之前db_req中有没有邮件
bool bDBMailExist = m_userMailStrategy->GetExistMailWithAttach(db_req->mutable_mails(), pDBMail);
如果存在给这些邮件直接添加附件
m_userMailStrategy->AddAttachTo(gameEle, pDBMail);
m_userMailStrategy->AddAttachTo(gameEle, pUserMail);
bool CUserMailStrategy::AddAttachTo(const struct_game_element& gameEle, db_user_mail* pDBMail) { ASSERT(pDBMail); ::google::protobuf::RepeatedPtrField< ::db_mail_attach >::iterator iter = pDBMail->mutable_attachs()->begin(); for (; iter != pDBMail->mutable_attachs()->end(); ++iter) { if (iter->mutable_element()->type() == gameEle.type()) { if (gameEle.type() != struct_game_element::EELEMENTTYPE_ITEM || iter->mutable_element()->id() == gameEle.id())//非道具类型直接叠加 { iter->mutable_element()->set_num(iter->mutable_element()->num() + gameEle.num()); return true; } } } db_mail_attach* pAttach = pDBMail->add_attachs(); pAttach->set_attach_id(CMailMgr::GetInstance()->CreateId(eIdType_MailAttach)); pAttach->mutable_element()->CopyFrom(gameEle); return true; }
说实话我不喜欢写这些代码,在某些特殊出现的情况下的优化,实在是太花时间,现在我要优化,看着这些我都蛋疼,这样的代码很容易出错,写的时候要小心,哎,还是按照这个模式来吧。
不过如果刚开始设计的好,这些需求实现起来应该也简单
