玩家上线

1.在GS这边发送(本地玩家信息)
 LocPlayerInfo info;
 InitLocalPlayer(rActorEx, info);
 SendCmd(s2c_local_player_info, &info, sizeof(info));
这个LocPlayerInfo好像内容比较多
struct LocPlayerInfo
{
 int id;
 wchar_t name[64];
 unsigned int nBodyID;
 int mapID;
 pos2d pos;
 ObjStat stat;
 SkillStat skillstats[100];    // 身上技能，最大个数
 int     nskill;     // 当前技能个数
 AttInfo     m_AttInfo;     // 属性值
};
2.进入map，初始化一些信息之后，发送
plchannel->m_fnSendLocalPlayerEnter(m_nMapId, plchannel->tgtPos);
这个位置是纠正后的位置，有可能玩家位置不正确，mapid和位置都已这个为准
3.客户端发送激活玩家的包
服务器在收到激活包之后
//这些都是相当重要的
void Map::ActivatePlayer(int mapChannelId) //激活玩家
{
 PlayerChannel* pPC = m_vecPlayerChannel[mapChannelId];
 if (pPC->m_bBeActived)
  return;
 pPC->m_bBeActived = true;
 auto& pActorInfoEx = pPC->m_pActorInfoEx;

 if (!pActorInfoEx->m_bGaming) 
 {//第一次进游戏
  pActorInfoEx->m_bGaming = true;
  StartGame(mapChannelId);//真心没看懂啥意思
 }     
 pos2d& cPlayerMapPos = m_spBase->GetMapPos(pPC->tgtPos); 
//    SetMapColl(mpos.x, mpos.y, true);
 GetAllPlayers()[pPC->objId.id] = pPC;//完全不知道干啥
 m_MapCellMgr.AddObj(cPlayerMapPos.x, cPlayerMapPos.y, pPC);//完全不知道干啥

 //在新进入块中通知
 pos2d newBlockPos = {pPC->m_nBlockX, pPC->m_nBlockY};
 pPC->m_fnSendStatChange(pPC->stat);//此处为什么发送状态包
 NotifyBlock(pos2d(), newBlockPos, pPC, true);

 //让玩家上线就能看到所有附近角色的动作。
 m_MapCellMgr.m_vecRolesBlock[pPC->m_nBlockX][pPC->m_nBlockY].Add(pPC);

 UpdateRegionInfo(pPC, cPlayerMapPos);//不知干啥的

 //判断罪恶值
 if(pPC->m_pActorInfoEx->GetSinValue() > 0)
 {
  m_spSinMgr->AddPlayer(pPC);
 }

 //宠物(现在主要是切图时宠物携带)
 if(pPC->m_pActorInfoEx->IsCarryTempPet())
 {
  const ShuiHu::PetInfo* pTempPetInfo = pPC->m_pActorInfoEx->GetTempPetInfoPtr();
  if (pTempPetInfo->m_nCurHP <= 0)
  {
   ShuiHu::GetLogger()->Warning("玩家(ID=%d)进入新地图(%d)，带了个血量为<=0的宠物(ID=%d)！",
    pPC->objId.id, m_nMapId, pTempPetInfo->m_nID);
   return;
  }
  pos2d cPetMapPos = {0};
  if (!Round(1, cPlayerMapPos, cPetMapPos))
  {
   pPC->m_pActorInfoEx->SetNoneTempPet();
   return; 
  }

  // 召唤正式宠物
  m_pSkill->CallPetByPos(pPC, *pTempPetInfo, cPetMapPos);
 }
