　　VR顯示器都帶有自動睡眠功能來避免螢幕老化 (burn-in)，但這對開發者或是展示時有很大的困擾，當VR顯示器進入睡眠模式後，體驗內容會造成畫面嚴重延遲，若在多人連線下則會造成伺服器與客戶端失去同步，在甦醒後還有機率會發生VR顯示器需要重新定位的問題。 －－－－－－－－－－－－－－－－－－－－ HP Reverb (適用其他ｗindows mixed reality體系頭盔) 　Enable Screen Saver Mode - 啟用螢幕保護模式 　此模式將停用睡眠模式，頭盔閒置時會關閉螢幕，但不會失去控制，直到重新戴上頭盔時螢幕會恢復顯示。 reg add HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Holographic /v ScreensaverModeEnabled /t REG_DWORD /d 1 　// 1 to enable screen saver mode 　// 0 to disable screen saver mode 　// Windows version 1903 or newer 　Set Idle Timer Duration To Default - 設定休眠間隔時間 (預設15分鐘) reg add HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Holographic /v IdleTimerDuration /t REG_DWORD /d 900000 　// Warning: Changing this idle timer to longer than the default can lead to Screen burn-in on Mixed Reality Headsets 　// The Mixed Reality Portal idle timer specified in milliseconds Oculus Rift S 　OculusCompatCheck.exe - 相容性測試 　// C:\Program Files\Oculus\Support\oculus-compat 　OculusDebugTool.exe - 除錯工具 (...

[UE4] TCP Socket 傳輸實現

程式碼 需要注意的地方 記得在Build.cs添加Sockets, Networking TcpClient.h virtual bool SocketReceive(); //這裡添加virtual關鍵字是為了未來覆載此方法來實現從封包中拆解出自訂的資料格式 TcpClient.cpp 可在ATcpClient::ATcpClient() {...}建構函式中給予資料成員一個初始值，避免資料異常 若你想同步變數 ATcpClient::ATcpClient() { 　bReplicates = true; // 啟用同步　 } // Replicate void ATcpClient::GetLifetimeReplicatedProps(TArray< FLifetimeProperty > & OutLifetimeProps) const { 　 Super::GetLifetimeReplicatedProps(OutLifetimeProps); 　 DOREPLIFETIME(ATcpClient, Tcp_UpdateRate);　// 你想同步的變數 } 在UE4停止運作時，確保有刪除Thread與關閉Socket void ATcpClient::EndPlay(const EEndPlayReason::Type EndPlayReason) { 　 if (m_RecvThread != nullptr) 　 { 　　 m_RecvThread->Kill(true); 　　 delete m_RecvThread; 　 } 　 if (Socket) 　 { 　　 Socket->Close(); 　　 ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->DestroySocket(Socket); 　 } 　 Super::EndPlay(EndPlayReason); } Byte to String & Byte to float // Byte to String FString(ANSI_TO_TCH...
