Input

If command line contains safe, UseRawHIDInput and UseDirectInput are turned off

In UnrealEd, and UseDirectInput is set, it will switch to RawHIDInput for the session - but only if EnableEditorRawHIDInput is set. Otherwise it will drop to legacy input modes as noted below.

Input system priority:

1. UseRawHIDInput wins if set. You get Windows Raw Input- unfiltered device input directly from hardware.
   • RawEnhancedPointerPrecision - enables (True)/disables (False) mouse acceleration using Windows EPP - see EPPCustomCurvePoints
2. UseDirectInput is next priority. You get Windows DirectInput from DirectX 8
   • DirectEnhancedPointerPrecision - enables (True)/disables (False) mouse acceleration using Windows EPP - see EPPCustomCurvePoints
3. If UseLegacyCursorInput is set then drops to a Legacy Win32 Input Handler
4. Otherwise, the game uses a Windows Win32 Input Handler

Other settings:

• StartupBorderless - When WindowedViewportX and WindowedViewportY are set to your current desktop resolution, and StartupFullscreen=False then the game window will be borderless taking up the entire screen size - however it is a window, not a full-screen session. Other windows can pop up in front of it.

Other settings that are not currently functional:

• InhibitWindowsHotkeys - does not appear to do anything. Intended to stop alt-escape. alt-tab, ctrl-escape and ctrl-tab from operating when full screen?

• WinPosX and WinPosY - where to open a windowed screen - however this does not appear to work.

Console command "SAVESCREENPOS" sets WinPosX and WinPosY to where the window is - however you do not appear to be able to move a window any longer
