上一篇文章中，出现一个问题：客户端玩家新加入session的时候，如果马上点加入房间会出现不能同步的问题，原因是玩家新加入的时候建立连接是需要时间的，在这过程中，RPC函数还未启动，所以解决方法是，加入session后，延迟一段时间后再执行带有同步的逻辑。
下面是出牌的流程图，顶部的client和server代表在客户端上和服务器上执行的逻辑。
注：提示牌部分涉及到单机类型的AI，先放一边，代替为强制出牌。
C++中，两个接口，一个是出牌逻辑，返回的是出牌结果，结果分为出牌成功，出牌失败且重新出，出牌失败且过下一个，直接过下一个
UENUM(BlueprintType)
enum class FPlayerOperationResultType:uint8
｛
//determine to operate falied
OperResNothing,
//operate successfully
OperResSuccess,
//operate falied ,continue doing
OperResFalied_NotPass,
//operate falied,pass
OperResFailed_Pass,
//operate successfully and be winner
OperResWinner
｝;
另外，数据传输过程中需要代码里的计算牌数据和客户端UI显示的牌数据之间的一个转换函数：
TArray<AMyCard*> AMyNewPlayer::GetCardsByUICardsFromClientCards(TArray<AMyCard*> _cardsOnClient, TArray<FCardUIData> _cardsUIData)
｛
TArray<AMyCard*> t_res;
TArray<AMyCard*> t_resNull;
if (_cardsUIData.Num() > 0 && _cardsOnClient.Num() > 0)
｛
int t_needNum = _cardsUIData.Num();
for (int i=0;i<_cardsOnClient.Num();i++)
｛
AMyCard* t_card = _cardsOnClient[i];
if (t_card)
｛
for (int j = 0; j < _cardsUIData.Num(); j++)
｛
FCardUIData t_uicard = _cardsUIData[j];
if (t_uicard.m_type == t_card->m_type&&t_uicard.m_numStr == t_card->m_numStr)
｛
t_res.Add(t_card);
break;
｝
｝
if (t_res.Num()== t_needNum)
return t_res;
｝
｝
｝
return t_res;
｝
出牌逻辑：
FPlayerOperationResultData AMyNewPlayer::OutCards(FPlayerOperationData _operationData)
｛
FPlayerOperationResultData t_res;
if (Role == ROLE_Authority&&_operationData.m_index == m_indexPlayer)
｛
if (_operationData.m_type == FPlayerOperationType::OutCards&&_operationData.NotNull())
｛
TArray<AMyCard*> t_cards = GetCardsByUICardsFromClientCards(m_cardsClient, _operationData.m_cards);
if (t_cards.Num() > 0)
｛
FCurrentGameData_Server t_dataServer = GetCurrentGameDataOnServer();
CardGroupType t_type = GetCardGroupTypeFromCards(t_cards);
//first out cards
if (!t_dataServer.NotNull())
｛
if (CheckOutCardsIfReliable(t_cards))
｛
t_res.Init(FPlayerOperationResultType::OperResSuccess, _operationData.m_cards, _operationData.m_index, "out cards successfully");
OutCardsSuccessFully(t_cards, t_type);
｝
else
｛
//wrong cards type ,out cards again
TArray<FCardUIData> t_tt;
t_res.Init(FPlayerOperationResultType::OperResFalied_NotPass, t_tt, _operationData.m_index, "wrong cards type ,out cards again!!!");
｝
｝
else
｛
//过了一轮，覆盖服务器出牌数据
if (t_dataServer.m_index == m_indexPlayer)
｛
t_res.Init(FPlayerOperationResultType::OperResSuccess, _operationData.m_cards, _operationData.m_index, "out cards successfully");
OutCardsSuccessFully(t_cards, t_type);
｝
//和当前出牌数据比较
else
｛
if (t_type != CardGroupType::Nothing)
｛
if (t_type == t_dataServer.m_type)
｛
if (CompareTwoCardsWithSameType(t_cards, t_dataServer.m_cards) == 1)
｛
t_res.Init(FPlayerOperationResultType::OperResSuccess, _operationData.m_cards, _operationData.m_index, "out cards successfully");
OutCardsSuccessFully(t_cards, t_type);
｝
｝
else
｛
int t_res1 = CompareTwoCards(t_cards, t_dataServer.m_cards);
if (t_res1==1)
｛
t_res.Init(FPlayerOperationResultType::OperResSuccess, _operationData.m_cards, _operationData.m_index, "out cards successfully");
OutCardsSuccessFully(t_cards, t_type);
｝
else if(t_res1==2)
｛
//actual num of cards is too small,out cards again
t_res.Init(FPlayerOperationResultType::OperResFalied_NotPass, _operationData.m_cards, _operationData.m_index, "actual num of cards is too small,out cards again!!!");
｝
else
｛
t_res.Init(FPlayerOperationResultType::OperResFalied_NotPass, _operationData.m_cards, _operationData.m_index, "wrong cards type ,out cards again!!!");
｝
｝
｝
else
｛
//wrong cards type ,out cards again
TArray<FCardUIData> t_tt;
t_res.Init(FPlayerOperationResultType::OperResFalied_NotPass, t_tt, _operationData.m_index, "wrong cards type ,out cards again!!!");
｝
｝
｝
｝
｝
else if (_operationData.m_type == FPlayerOperationType::Pass)
｛
//if force to out cards
if(CheckIfForceOutCards())
t_res.Init(FPlayerOperationResultType::OperResFalied_NotPass, _operationData.m_cards, _operationData.m_index, "force to out cards");
else
｛
TArray<FCardUIData> t_tt;
t_res.Init(FPlayerOperationResultType::OperResFailed_Pass, t_tt, _operationData.m_index, "pass~~~~~");
｝
｝
｝
return t_res;
｝
另外一个接口就是控制出牌玩家。在服务器上根据下标来决定哪个玩家轮到出牌。
FPlayerOperationData AMyNewPlayer::TurnToOutCards()
｛
FPlayerOperationData t_res;
if (Role == ROLE_Authority)
｛
int t_next= GetNextPlayer(m_indexPlayer);
if (t_next >= 0)
｛
TArray<FCardUIData> tt;
t_res.Init(FPlayerOperationType::ReadyToOutCards, tt, t_next);
｝
｝
return t_res;
｝
显示到客户端UI的思路和之前一样，牌型的判断算法下一篇文章具体说明，因为之前写好的，所以这里就暂且跳过。
