1. 點擊C++類文件夾，在右邊的區(qū)域點擊鼠標右鍵，在彈出的菜單中選擇“新建C++類”
   
2. 在彈出的菜單中選中“顯示所有類”，選擇GameInstanceSubsystem作為父類, 點擊“下一步”按鈕
   
3. 輸入子類名稱“UVRVIUOnlineGameSubsystem”，選擇插件作為新類的目標模塊，點擊“公共”選擇器
   

4. 打開C++工程，找到".Build.cs"文件，在“PublicDependencyModuleNames”下，添加"MultiPlayerPlugin"
   

   1 2 3 4 5 6 7 8 9 10 11

   public?class?LandMaster : ModuleRules { ????public?LandMaster(ReadOnlyTargetRules Target) : base(Target) ????{ ????????PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs; ?? ????????PublicDependencyModuleNames.AddRange(new?string[] {?"Core",?"CoreUObject",?"Engine",?"InputCore",?"UMG",?"Http",?"Json",?"JsonUtilities",?"Sockets",?"Networking",?"OnlineSubsystem",?"OnlineSubsystemUtils",?"MultiPlayerPlugin"?}); ?? ????????PrivateDependencyModuleNames.AddRange(new?string[] {?"Slate",?"SlateCore"?}); ????} }

5. 設置“MultiPlayerPlugin.uplugin”文件

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

   { ????"FileVersion": 3, ????"Version": 1, ????"VersionName":?"1.0", ????"FriendlyName":?"MultiPlayerPlugin", ????"Description":?"plugin for multi player ", ????"Category":?"Other", ????"CreatedBy":?"VRVIU_Jacky", ????"CreatedByURL":?"", ????"DocsURL":?"", ????"MarketplaceURL":?"", ????"SupportURL":?"", ????"EngineVersion":?"4.26.0", ????"CanContainContent":?true, ????"Installed":?true, ????"Modules": [ ????????{ ????????????"Name":?"MultiPlayerPlugin", ????????????"Type":?"Runtime", ????????????"LoadingPhase":?"Default", ????????????"WhitelistPlatforms": [ ????????????????"Win32", ????????????????"Win64" ????????????] ????????} ????] }

6. 設置插件“.Build.cs”文件，添加需要引用的模塊

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54

7. 獲取本機IP地址

   1 2 3 4 5 6 7 8 9 10 11 12 13 14

   FString UVRVIUOnlineGameSubsystem::GetIpAddress(bool?bHasPort?/*= true*/) { ????FString IpAddr("NONE"); ????bool?canBind =?false; ????TSharedRef<FInternetAddr>LocalIp = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->GetLocalHostAddr(*GLog, canBind); ????if?(LocalIp->IsValid()) ????{ ????????IpAddr = LocalIp->ToString(bHasPort); ????} ????return?IpAddr; }

8. 創(chuàng)建會話

   1 2 3

   FString cmd =?"open "?+ Map +?"?listen"; UGameplayStatics::GetPlayerController(GetWorld(), 0)->ConsoleCommand(cmd); m_ServerAddress = ServerAddress.Len() == 0 ? GetIpAddress(false):ServerAddress;

9. 加入會話

   1 2 3 4 5

   UE_LOG(LogTemp, Warning, TEXT("UVRVIUOnlineGameSubsystem::ConnectServer %s"), *IntranetIP); FString cmd =?"open "?+ IntranetIP; UGameplayStatics::GetPlayerController(GetWorld(), 0)->ConsoleCommand(cmd); m_ServerAddress = IntranetIP;文章來源地址http://www.zghlxwxcb.cn/news/detail-858818.html
