227 release notes/v227j

Below are the patch release notes for OldUnreal Patch 227j. The below compilation is a list of all changes that were publicly listed in release threads and public changelogs, or contained in Git commit messages since the project moves to a GitHub repository. Due to the nature of the project schedule and the small development team, numerous small changes may have gone under the radar.

Release date

  • June 23, 2022

TL;DR version

Honestly, it's impossible. But we can try mentioning the most important changes on this patch:

  • Audio:
    • Tons of fixes to OpenAL and SwFMODEx.
    • Added Speech Volume in order to control the volume of monster grunts, RTNP Marines and custom dialogue voicelines.
  • Editor:
    • New Hint System which uses the comments of the UScript in order to display what certain functions do.
    • New switch in View Menu to enable/disable lighticon in lightcolor.
    • Now it's possible to build very large and complex spheres without the Editor crashing!
    • SkeletalMeshes can now be copypasted.
    • Actors can be copy+pasted in selected position via RMB menu.
    • ucc packageflag doesn't generate corrupt .unr files anymore.
    • Brush Scaling and Brush Stretching were extended to Actor Scaling and Actor Stretching.
    • With RMB the builder brush can transform the current shape into a dynamic zone.
    • New RMB menu option to replace the actor while keeping the same modifier properties.
    • Moved all hidden (uncategorized) properties to a "Hidden properties" category in properties window, also color coded to red.
    • Added an option (enabled by default) to make rotation angles show in radii angles (0-360 range) rather then UU angles (0-2^16 range). Setting is at: UseRegularAngles=False under [Core.System].
    • Maps that have missing packages are now allowed to be partially loaded (they will still give a map load warning at first and ask Y/N if you want to load them anyway).
    • Added a portal directional arrow for WarpZoneInfo to help identify what direction the portal is currently facing at.
    • Added Actor.bBlockAISight which makes AI not be able to see through the actor (must have bCollideActors enabled but can be non-blocking).
    • Added support for custom actors to be placed now with a Brush collision shape attached to it (Actor must have bSpecialBrushActor enabled).
    • Added a 'Play from here' right-click menu option to editor 3D viewport.
    • Added right-click menu for properties window in order to allow user to copy variables information to clipboard.
    • Made UnrealEd track modified packages and ask if each one of them should be saved on exit.
    • Made non-compiled script classes non-placeable in editor.
    • Added Tooltip for object classes to show header comments of the class you're hovering over.
    • Added functionality to rename asset groups too (texture/sound/mesh etc).
    • Added right-click menu for sound browser.
    • Added a minimum properties window size to avoid 1 pixel size properties window bug.
    • Disabled in-game keybindings from firing inside editor.
    • Fixed editor from losing focus when closing a sub-window after using alt-tab (win 10).
    • Made sounds not reset nor music stop when you paste actors in editor.
    • Added a song section slider to Music Browser so you can listen to specific sections of the song.
    • Added support for custom editor keybindings (see Unreal.ini, EditorEngine.KeyBindings).
    • Added right-click BSP surface options to Merge faces (on a tesselated surface) and Flip faces (incase they are facing the wrong direction).
    • Added editor option to disable saving of LevelSummary object (if you want save map as pre-226 compatibility, found in Advanced Options).
    • Made editor save all modified packages to System/Backup folder if editor crashes.
    • Added support for importing 2-bit or 4-bit PCX textures.
    • Added LiftExit variant LiftJumpDest which tells AI to lift-jump to an area.
    • Made editor "Show paths" show exact path size values of routes with selected path nodes.
    • Implemented OBJ Brush exporter/importer.
    • Made DumpIntCommandlet merge changes with all languages.
    • Tons of other minor fixes and additions.
  • Engine:
    • Made player footsteps cause wave ripplets on FluidSurfaceInfo as you walk in it.
    • Due to complaints about lighting differences in 227, especially because of the feedback from people doing some conversion from UT maps, added a new switch which enables SpecularLighting effect for all maps unless a specific new flag is set: var() bool bSpecularLight;. This means that 227 mappers would want to disable this flag to have the known and more accurate 227 lighting, but old and already ported maps have the 226/UT behavior. Maybe should have done from the begin with, because this means now more work for 227 mappers, especially for already finished maps, but this allows everyone to take the preferred method after all.
    • Added triggered MaterialSequence animation.
    • Fixed some timer issue for windows version, depending on appSeconds(), which causes mostly a problem for servers in relation with MaxTickRate. It seems that only a few systems are affected by this problem (maybe depending on hardware/bios). This bug is existing in all versions before, including 224,225 and 226.
    • Added path builder information with customizable variables to LevelInfo to allow mappers building maps with different settings or for other UEngine games with UED2.1.
    • Fixed: Server doesn't inform clients about closing old connections on map change.
    • Fixed: Bug in banning system may cause duplicate (false) entries.
    • Added delta compression for saved games, also made saved games files contain save information along with a screenshot preview to show on load game menu.
    • Added commands "STAT THREAD" to display number of running threads and "THREADS" to display a list and description of running threads in memory (for Unreal).
    • Added Sound compression/decompression support for all audio drivers. You can compress sounds in sound browser or in UnrealScript by defining "OGG=X" (X is the quality in range of 0-11, 0 = worst, 11 = best) in #exec audio import line or then you can directly import ogg files as sounds.
    • Added support for defining HD HUD textures, by either setting Texture.HDTexture or in UnrealScript add "HD=XXX" to #exec texture/font import lines. HD texture will be used if texture is being stretched out by at least +25% of its original size.
    • Made it possible to enter spaces in names in properties and defaultproperties blocks.
    • Added ZoneInfo.MinWalkableZ to tell physics engine how steep slopes Pawns can walk on.
    • Implemented Alt+F4 hotkey to exit the game instantly.
    • Improved Log window to support command history browsing (up/down arrows) also properly support selecting/replacing parts of text or insert text in middle of command.
    • Added support for Sub-Levels architecture (where you can link multiple maps together into one with seamless level transition). See LevelInfo.SubLevels array.
    • Added GrassDeco actor for a Source Engine style grass sprites in levels (also GrassDecoSchool for an automatic grass patch).
    • Added support for custom mouse cursors in-game (directly use regular Textures), see Engine.UnrealCursor class.
    • Disable initial garbage collection when booting up the game (waste of time).
    • Made it impossible to try to load package 'nul' to prevent malicious loading crashes.
    • Added Volumes support from UnrealEngine 2+ (which can be used to create brush shape collision shapes or triggers to levels).
    • Made LadderTrigger a Volume instead, also various fixes to ladder:
      • Player properly hops off the ladder now at top.
      • Added a flag to allow player to strafe on ladder (you must have bDirectional enabled).
      • Added a flag to enable/disable directional ladder which makes you drop off the ladder if you look away from it (must also have bDirectional enabled).
      • Pressing jump key while holding backwards now makes you now jump off ladder backwards.
      • Added a value to control climbing speed on the ladder.
    • Added INI file option 'LangPath' which can be used to specify directory of language files (like .int).
    • Added a variable to SkyZoneInfo which allows you to make sky move in relative to player camera position.
    • Added support for static light static mesh movers.
    • Added ClientMover actor for a client-side background looping movers (which doesn't interact with gameplay in any way).
    • Added TransporterVolume which can be used to transport all actors touching that volume to a relative offset in another place in level. Similar to Transporter but with better control.
    • Disabled Password logging by default game modes.
    • Fixed INI file writer failing if trying to write really long ini lines.
    • Added PhysX physics support (with Physics=PHYS_RigidBody and PhysicsData reference in actor).
    • Added a Pawn PhysicsAnimation object which can be used to give pawns automatic physics based animations.
    • Made package loader load meshes as any mesh type (regular Mesh can now load as LodMesh/SkeletalMesh/StaticMesh etc...).
    • Added a new BSP surface flag 'invisible occluder' which works like an anti-portal surface to simply occlude view.
    • Fixed players unable to walk inside warpzones.
    • Added option to MusicEvent to disable cross-level song changes (when using sub-levels).
    • Added PhysX option for Emitter particles to make them rigid.
    • Added particle fade style option (to make particles change style only while fading).
    • Added LevelInfo.MaxPortalDepth to control how many layers warpzones/mirrors/skyboxes can draw.
    • Made UnknownXX keybindings not configurable, and therefore wont show up in User.ini.
    • Added consolecommand "DUMPSTATES <classname>" to dump state execution information of all matching actors currently in level.
    • Fixed Advanced Options window to correctly handle sub-section naming conflicts (such as <Advanced Options - Advance> vs <Advanced Options - Editor - Advance>).
    • Added a LevelInfo flag bUTZoneVelocity to make ZoneVelocity behave like in UT games (defaults to True on levels saved in UT editor).
    • Added GameInfo.GameMaxChannels which controls the max number of channels 227j+ clients can have on the server (valid range is 256-65536).
    • Added an INI/INT formatting for color codes, works with following formatting: (#HTML color tag), as example: (#FFFF00) = yellow color.
    • Made string properties with some special characters gets written with a special text tag into INI (tags are \%HEX or \%n or \%").
    • Fixed a memory error when a Mesh or LodMesh has a surface with a vertex index that goes out of range.
    • Also added a Teleporter.bUTRotationMode flag which is set to true also when loading UT maps. To make teleporters behave exactly like in UT.

    • Fixed game from crashing if you delete a navigationpoint that is referenced by a reachspec.
    • Made game de-reference deleted lights and zoneinfos on map load.
    • Fixed loading of some UT maps that have incorrect LightEffect=LE_Sunlight reference, making level oddly bright (CTF-November).
    • Implemented a hack fix for RedeemYourSpace map pack, to force player to touch any teleporters under their MaxStepHeight while standing on a mover moving downwards.
    • Added features for JumpPads: a flag to disable it for monsters or players, made it trigger an event when used and triggering it will toggle if its enabled or disabled.
    • Added support for multiple language paths.
    • Added to LevelInfo flags to disable level specific rigidbody physics (bDisableRbPhysics/bDisableSubLevelRbPhys - if you know you wont need it).

    • Made bonus difficulty levels show in red on classic menu.
    • Changed mechanics of bonus difficulty levels to not increase health of monsters, but to alter their AI behaviour.
    • Fixed an ScriptWarning when Weapon InstantFire ends up killing player owner.
    • Fixed some mismatching font characters on LargeFont and BigFont (? and + characters being inverted).

    • Added XOpenGL OpenGL3 / OpenGL4 renderer. Note: You need to have at least an OpenGL 3.3 capable card to use this renderer!
    • Fixed: Coronas being blocked by BlockAll (ignores bHidden).
    • Added a catch for crippled meshes could crash renderer (d3d9/opengl) when using hwclipping.
    • New Quadshot firstperson model and animations.
    • Fixed Software render to draw projectors and trail emitters.
    • Changed Software render to draw alpha blended textures as masked (masking invisible parts).
    • Fixed static meshes (or any other bShadowCast actors) to cast shadows over dynamic actors.
    • Added PortalModifier object which can be assigned to Texture (to be applied when drawing portal through it), ZoneInfo (to be applied when camera is inside it), or PlayerPawn (for mod override), which can be used to replace several rendering factors, such as disable lighting/fog/modify distance fog or replace textures etc. (see Object > PortalModifier).
    • Fixed Direct3D9 flickering with BSP and distance fog.
    • Added support for hardware clipping planes to D3D9 and OpenGL.

    • Added various HD icons for when you use hi-res HUD mode. (Thanks Krull0r)
    • Fixed zoneportals from hiding skybox in additive maps.
    • Fixed so render supports unlimited screen res Y size (was limited to 2880).
    • Fixed two sided meshes to receive lighting from both sides again.
    • Made volumetric fogs draw on zoneportals and sky (sky fog one is optional and can be changed from video settings between high quality/low quality/disabled options).
    • Made game draw volumetric fogs in fogzones even if player is standing outside of any fogzones.
    • Made volumetric fogging to be rendered on unlit actors.
    • Made map projectors properly project on any actors it touches (if bOnlyAttachStaticActors is False).
    • Made projectors project on first person weapon mesh too if it projects on player model itself.
    • Made shadow bitmaps ignore translucent mesh surfaces so they don't cast shadows (so pawn muzzle flashes dont draw ridiculous shadows).

    • Fixed meshes disappearing on mirror reflections on a lot of cases.
    • Added a separate MeshDetailTextures option for render drivers to disable/enable detail textures on meshes.

    • Fixed so that invisible static meshes don't block lighting in-game.
    • Added a CPU usage limit to skybox fogging.
    • Corrected Krall mesh mouth clamps not being masked.
    • Changed when player teleports to a new area it wont fade-in lighting to new area, but instead instantly swaps it.
    • Added render option to how aggressively it should reduce BSP lightmap framerate detail ("Lightmap LOD" in UMenu).
    • Added actor shadow occlusion distance ("Shadow draw distance" in UMenu).
    • Fixed weapon muzzle flashes to be drawn during translucent render pass instead of same time as owner player itself, prevents muzzle flash from being drawn behind terrain meshes.
    • Fixed decals to not to render on rotating mover surfaces to prevent them from glitching out.
    • Implemented some HD game fonts by Krull.
    • Fixed a bug where HUD scaling would stop working on HUD messages while UWindow was open.

    • Lots of fixes on already existing D3D9Drv, D3D10Drv, OpenGL.
    • Lots of fixes on meshes.
  • Physics: Added PhysX physics support (simple rigidbodies and joints).
  • UnrealScript: Too many to count. Check the main Release Notes.
  • Server:
    • Updated webadmin interface, now it is partially native codes based, new native features include:
      • Image/binary file web response.
      • Binary file downloading from client.
      • Better support for huge data handling.
      • Advanced options property listing.
    • New web pages:
      • File upload (for simple mod uploading).
      • Advanced options.
      • Web admin accounts manager.
    • Misc features/improvements:
      • Fixed problem where sometimes messaging spectator wouldn't spawn, thus didn't allow for viewing chat log.
      • Added webadmin privilege levels for accounts (0-minimum, 255-maximum privileges).
      • Added DoS connection detection (to block off users that rapidly try to connect to webadmin with different passwords).
    • Fixed UCC.exe Server commandlet to accept command input.
    • Made clients verify cache files GUID version before using them.
    • Added server command: UVerifyClient <ID> to manually verify a single or all clients packages with HASH values to verify they are in network sync.
    • Fixed GameInfo to not send game options to clients when switching levels.
    • Increased maximum MaxClientRate value to 1,000,000.
  • New in-game features:
    • Added NoRunAway option into Unreal.ini [Core.System] to enable old crash behavior with RunAwayLimit, to help modders in developing and debugging.
    • New commands:
      • CacheRip <package>: Rips a specific package
      • CacheRipAll: Rips all packages from the server you are currently in.
      • CacheRipMap: Rips current map and dependencies. In order to avoid confusion, it just grabs the info from the server and uses it to rip the stuff from local cache directory. No server overhead is produced.
        Note that determining the file extension correctly is only working on 227 servers, older servers don't provide the information needed. This way only maps can be identified, any other file will get the extension .u - which will work for Unreal but the disadvantage of that is obvious.
    • Added a new option ContinuousKeyEvents as a client setting to enable old behavior to continue running when typing
    • New supported prefixes for URL sharing via game chat: mailto:, http://, https://, ftp://, www., ftp., unreal://
    • Added flag to level info for SupportsCrouchJumping, which will enable crouch-jumping.
    • Added FAKELAG <ping> consolecommand for server to fabricate lag (for debugging).
    • Made HTTP downloading clients notify server of their download progress (for UnrealScript to catch serverside).
    • Fixed LevelInfo.bCheckWalkSurfaces to work. It will make Texture.Friction scale Pawns walking friction (if you use Friction 10, it will function as a ladder texture, similar to Half-Life).
  • v469 Backports:
    • Backported fixed Pawn walk along ledges code.
    • Implemented some UTF-8 format fixes.
    • Pulled some render buffer overflow handling code to fix some specific render crashes.
    • Fixed editor to remember better what viewports had what render devices selected.
    • Implemented shoulder button support (aka Button4 and Button5) for Win32 mouse input.
    • Updated DirectInput from version 3 to 8. The former is utterly broken on Win10/11. The latter sort of works.
    • Fixed various DirectDraw issues on Win10/11.
    • Added InhibitWindowsHotkeys option to UWindowsClient. If set to its default value of FALSE, the game no longer blocks the Alt+Esc, Alt+Tab, Ctrl+Esc, and Ctrl+Tab hotkeys. Setting the option to TRUE restores the original UE1 behavior.
    • Removed SlowVideoBuffering from UWindowsClient because this option no longer works on Win7+
    • Made the DirectInput mouse handling code read the full DIMOUSESTATE2
    • Made DXGI renderers (i.e., D3D10Drv and D3D11Drv) no longer mess up your WindowedViewportX and WindowedViewportY settings while ALT+Entering
    • Disabled EnhancedPointerPrecision by default, except in Unreal Editor
    • Fixed several bugs that broke mouse input in Unreal Editor if you had raw input enabled in-game
    • Fixed a bug that could cause GetClipboardText to read invalid data from the clipboard
    • Made UWindowsViewport::ShutdownAfterError send a WM_FORCEMINIMIZE to the viewport window. This fixes a bug where the viewport remains visible if the game crashes with raw input active
    • Made lighting rebuilds use a minimal null renderer (WinDrv.TemporaryRenderDevice). This should speed up lighting rebuilds
    • Fixed several bugs that caused raw input not to capture the mouse correctly when switching between windowed and fullscreen mode
    • Fixed several bugs that could cause the windows mouse cursor to remain visible after switching between windowed and fullscreen mode
    • Fixed a bug that made TryRenderDevice crash the game when you tried to switch to a renderer that is already active
    • Made SoftDrv correctly reinitialize the DibSection after changing the viewport resolution
  • Linux:
    • In order to fix some old crappy problems and missing abilities in Linux, added SDL2Drv and SDL2Launch for Linux. In order to do that all old SDL stuff becomes deprecated and won't make it into 227j: SDLDrv, SDLLaunch, SDLGLDrv, SDLSoftDrv. That's nothing to worry about though, since these have been kept mostly as reference and have no features which could be compared to OpenGLDrv, which can be used in any Linux distro with at least Mesa. Details can be found here: http://www.oldunreal.com/cgi-bin/yabb2/YaBB.pl?num=1424370983/0#0
    • Updated Linux SDL to SDL2Drv.
    • Added SDL2 store window position
    • Added Linux ARM port.
    • SDL2Drv added support for RefreshRate
    • Fixed relaunch command.

Audio

  • (03/03/13) Some fixes for SwFMod (FModEx) audio driver:
    • Fixed ambient sounds to use game volume and not play at max volume at all time.
    • Fixed so ambient sound effects with unknown sound source (net games) to stop sound once out of hearing distance (instead of keeping the sound until mapchange).
    • Fixed consolecommands GetMusicOffset, SetMusicOffset and GetMusicLen to use correct music offset values for modules.
  • (10/29/13) Switched in OpenAL from FMod Music output to libxmp. This player is not only free and open source (GNU LESSER GENERAL PUBLIC LICENSE), but better portable and is yet actively maintained unlike most other players. It also plays some tracker files "more correctly" than old FMod3. OGG playing is now done directly via ogg vorbis (BSD-License).
  • (10/29/13) Added CrossFading ability in OpenAL when using MTRAN_Segue.
  • (05/26/15) ALAudio:
    • added AL_METERS_PER_UNIT to ALAudio to be more precise with Unreal UU's
    • removed ALAudio.u as its not needed anymore for 227 but added EFX.u which is a separate package in case one wants to use customized audio effects instead of presets. This file is also independent from ALAudio.dll, means if you use it in your maps anyone can download the package even although not using or having ALAudio.dll (it won't work then of course but doesn't do any harm either). This will allow also any mapper to make use of ALAudio in other UEngine games without having dll dependencies (builds will follow soon). Thanks to Han for that change!
    • It also contains a couple of cleanups again and a new libxmp 4.3.8 (see http://xmp.sourceforge.net/ for update details, fixes/improvements).
  • (01/06/15) Added SpeechVolume setting (ALAudio, SwFMOD, Galaxy): It sets volume of all SLOT_Talk events, to set these separately if wanted and is giving a finer control for overall sound experience. In-game, usually monster sounds use it (grunt, death sounds etc.), but also the speech of the marines known from RTNP. Should be also helpful for example in dialog sequences in custom maps & mods.
  • (03/09/15) Fixed: Improved ALAudio looping wav code. Thanks Shivaxi for pointing it out!
  • (12/19/20) Anth: Fixed Galaxy audio accessing outside of memory bounds when playing some sound effects.
  • (03/24/21) Anth: Fixed choppy Galaxy/ALAudio playback.

Editor

  • (02/20/13) Added a hint system to UED2.1 for in game variables, which displays the content of the comment out of uscript. Simply right mouse click on any variable in the property window will open a messagebox with the corresponding help text. Left or right mouse button will close it again.

  • (12/27/12) Changed CloudZone to avoid crashes with monsterspawners not avoiding to spawn monsters there.
  • (10/28/13) Due to complaints about lighting differences in 227, especially because of the feedback from people doing some conversion from UT maps, added a new switch which enables SpecularLighting effect for all maps unless a specific new flag is set: var() bool bSpecularLight;. This means that 227 mappers would want to disable this flag to have the known and more accurate 227 lighting, but old and already ported maps have the 226/UT behavior. Maybe should have done from the begin with, because this means now more work for 227 mappers, especially for already finished maps, but this allows everyone to take the preferred method after all.
  • (11/30/13) Added triggered MaterialSequence animation.
  • (12/01/13) Fixed so "GoodCollision" movers don't clip through player if large enough and moves fast enough into player. Also changed so if you are inside the mover you can leave from it without it blocking you.
  • (05/22/14) Fixed some timer issue for windows version, depending on appSeconds(), which causes mostly a problem for servers in relation with MaxTickRate. It seems that only a few systems are affected by this problem (maybe depending on hardware/bios). This bug is existing in all versions before, including 224,225 and 226.
  • (05/26/15) Added path builder information with customizable variables to LevelInfo to allow mappers building maps with different settings or for other UEngine games with UED2.1:
// Pathbuilder - these settings are for advanced pathing or usage of UED2.1 for other UEngineGames. Changing these settings can cause extremely weird behavior, Don't mess with it if you don't know what you are doing.
var(PathBuilder) config int MaxCommonRadius;//      max radius to consider in building paths, default 70
var(PathBuilder) config int MaxCommonHeight;//      max typical height for non-human intelligent creatures, default 70
var(PathBuilder) config int MinCommonHeight;//  min typical height for non-human intelligent creatures, default 40
var(PathBuilder) config int MinCommonRadius;//  min typical radius for non-human intelligent creatures, default 24
var(PathBuilder) config int CommonRadius;      //  max typical radius of intelligent creatures, default 52
var(PathBuilder) config int HumanRadius;      //  normal player pawn radius, default 18
var(PathBuilder) config int HumanHeight;    //      normal playerpawn height, default 39

    • AlphaBlend Meshes are not affected by fog. Affected renderers: Direct3D9, OpenGL, XOpenGL.
    • TrailEmitters render incorrectly. Affected renderers: XOpenGL.
    • Beam Emitters are affected by fog, making the beam a solid color. Affected renderers: Direct3D9, OpenGL, XOpenGL.
    • DistanceFog affects emitter particles. Making particles look like squares on things like SpriteEmitters. Affected renderers: Direct3D9, OpenGL, XOpenGL.
    • Switching to XOpenGL breaks texture filtering on BSP (everything looks like the No Smooth flag is set) for the first launch. Closing the game and restarting fixes the texture filtering. Affected renderers: XOpenGL (duh).
    • DistanceFog affects TrailEmitters. Making the trail a solid color. Affected renderers: XOpenGL.
    • DistanceFog causes artifacts on a Fake Backdrop/Skybox. Affected renderers: XOpenGL.

      Notes: looks like UseFragmentProgram was broken upon implementing exp and exp2 fog. Can't be fixed unless one writes corresponding fragment programs for D3D9, so mask problem on meshes is now fixed, but no exp and exp2 fog for D3D9 users with UseFragmentProgram enabled.
    • DistanceFog renders outside of correct zones even with bZoneBasedFog enabled. Affected renderers: XOpenGL.
    • Meshes always look unlit. Affected renderers: XOpenGL.

UnrealScript

  • (12/09/12) Added a new native function to PlayerPawn to get current client version: native final function int GetClientVersion();.
  • (12/09/12) Added a new PlayerInterpolating state to PlayerPawn to be used on 227 clients when entering "PlayerPath" on SpecialEvent, it allows for online smooth interpolation movement.
  • (06/07/13) Added some new features:
    • Variable keyword EditInLine lets you create new objects of desired metaclass and edit its variables in properties window, looks like this: www.klankaos.com/downloads/Properties.jpg
    • Variable keyword AutoDestruct will destroy and cleanup the object instantly from memory when actor is destroyed. This way you can store additional data on objects for actors and have it released from memory as actor dies.
    • Any object or class variables have a dropdown box to select from a reference in memory (in properties window).
    • Added new function for ScriptedTexture: DrawPortal, it uses software render device to draw a portal from any point in level on a texture (and works really fast).
    • Added PostTouch/PendingTouch functionality from UT as-well.
  • (01/07/14) Fixed: Memory leak in dynamic array handling, improvements (DynArrayElement/Array_Insert/Array_Remove)
  • (10/03/14) Added new compiler directive for UnrealScript, a C++ style variable evaluator: <bool statement> ? <value if true> : <value if false>. So you can write for example: KillerName = Killer!=None ? Killer.MenuName : "Someone";. However, this will make your mod unloadable in pre-227 clients, crashing with unknown token error.
  • (02/08/15) Changed PerObjectConfig support to output format like in UnrealEngine 2+:
    [SomeClass ClassName]
    Config values...

    It will convert old config entries it finds in old to new format to prevent problems with ini updates. This should also prevent some possible abuse with using PerObjectConfig to overwrite some other config.
  • (02/08/15) Added 2 new native functions:
    • native static final function ClearConfig();
      Removes the PerObjectConfig ini entry for the object.
    • native static final function array<string> GetPerObjectNames( string ININame, optional string ObjectClass, optional int MaxResults /*unlimited if unspecified*/ );
      Finds all specified PerObjectConfig ini entries from an ini file.
  • (05/26/15) Fixed: upak predators may crash or freeze the game (thanks dots).
  • (06/22/15) Added missing color operators:
// Color operators
native(549) static final operator(20)  color - ( color A, color B );
native(550) static final operator(16) color *  ( float A, color B );
native(551) static final operator(20) color + ( color A, color B );
native(552) static final operator(16) color * ( color A, float B );
  • (08/10/15) Added autoloading of UFactories and UExporters based on int entries to UCC. This way you can extend the capabilities of the batchexport commandlet, like adding an *.3ds file exporter for Meshes. I used this in Deus Ex to add the capability to export Text packages using batchexport.
[Public]
(Name=RevisionEditor.RevisionExtStringExporterTXT,Class=Class,MetaClass=Core.Exporter)
  • (08/10/15) New native functions native(273) final function StopSoundSlot( ESoundSlot Slot ); and native(274) final function StopAllSoundSlots();. These functions stop the specified or all sound slots for an Actor. These functions are network transparent, but unlike PlaySound() use a reliable network replication pattern and do no distance checks. They share the same behaviour regarding simulated functions and invokation on network clients as PlaySound() does. This includes that you need to run those inside a simulated function when PlaySound() for that slot was called inside a simulated function (note that the server can invoke playback of a sound inside the same slot as the client for an given actor and they will both be played at the same time, so sound slots are not mutually exclusive in this situation!). In order to avoid problems in netplay you should ensure that there is a slight amount of time between PlaySound() and StopSoundSlot()/StopAllSoundSlots() call, so both will likely be execute in order on the network client (note that the same argument applies to multiple PlaySound() calls for the same channel, so this is no new issue introduce by these functions).
  • (08/15/15) Merged in some commandlets out of HTK:
    • AudioPackageCommandlet: Brought from Unreal II, it's an automated sound package generator. If you specify a directory with .wav files in it, this commandlet will build an .uax file with those Wave file imported.
    • MusicPackagesCommandlet: Batchconverts a directory full of music source files into a directory full of umx files.
    • ReduceTexturesCommandlet: Moves the compressed textures to the slot of the uncompressed ones, so you can have pure s3tc packages.
    • SaveEmbeddedCommandlet: Extracts embedded objects from a package.
    • ListObjectsCommandlet: Lists the Objects inside a package.
    • DumpTextureInfoCommandlet: Prints out a detailed info about textures inside a package.
  • (10/26/15) Added VClampMode=VClamp and UClampMode=UClamp texture import parameters, to be able to set ClampMode at compile time, for example: #exec TEXTURE IMPORT NAME=Bg11 FILE=Textures\Bg-11.pcx GROUP="Icons" MIPS=OFF VClampMode=VClamp UClampMode=UClamp.
  • (10/28/15) Editor.EditorEngine now optionally uses ini:Engine.Engine.EditorRender/ini:Engine.Engine.EditorViewportManager settings instead of ini:Engine.Engine.Render/ini:Engine.Engine.ViewportManager settings if those are specified in the ini file.
  • (03/15/16) Added from DeusEx the idea for var(Frob) bool bIsFrobable; (to manipulate or adjust, to tweak this actor over Frob() interface.) which is placed in actor, with the additions, in Pawn, as new helper functions for mods, of:
    • var() float MaxFrobDistance;
      Max distance frob checks are being done.
    • var transient Actor FrobTarget
    • function HighlightCenterObject()
      Checks to see if an object can be frobbed, if so, then highlight it.
    • function bool IsFrobbable( Actor Actor )
    • In order to make this work, these new functions have been added to actor:
//
// Fixed and extended version of TraceTexture() which also returns
// the Texture hit (Hint: There are Sound properties on Texture).
// Extended version of TraceActors which returns additional Texture info on Mover / LevelInfo hit.
//
native(1760) final iterator function TraceTextures
(
	Class<Actor> BaseClass,
	out Actor    HitActor,
	out Texture  Texture,
	out Name     TextureName,
	out Name     TextureGroup,
	out int      TextureFlags,
	out Vector   HitLocation,
	out Vector   HitNormal,
	Vector       TraceEnd,
	optional Vector TraceStart,
	optional Vector TraceExtent
);
//
// First Hit variant of TraceTextures.
// (The same as Trace is to TraceActors)
//
native(1761) final function Actor TraceSingleTexture
(
	Class<Actor> BaseClass,
	out Texture  Texture,
	out Name     TextureName,
	out Name     TextureGroup,
	out int      TextureFlags,
	out Vector   HitLocation,
	out Vector   HitNormal,
	Vector       TraceEnd,
	optional Vector TraceStart,
	optional bool bTraceActors,
	optional Vector TraceExtent
);

  • (11/11/19) Added support for 'skip' parameters to regular native functions (not just operators second parameter).
  • (11/11/19) Made "replace to" parm in "ReplaceStr" skippable, meaning it wont get evaluated if there are no replacements found.
  • (11/11/19) Fixed ternary operators (<condition> ? <value if true> : <value if false>) to support l-values (and fixed a compiler bug with them).
  • (11/11/19) Added "typecast" compiler keyword (can be used to hard cast any value to any type), for example: int i = typecast<int>(Class) will grab pointer value of 'Class'. Using this feture is compatible with any Unreal version.
  • (11/11/19) Added struct constructor function: plane p = construct<plane>(2,0,1,0) or plane p = construct<plane>(X=2,Z=1) (both methods works), which is faster then manually assigning each struct value in script but slower then using vect or rot constants.
  • (11/11/19) Fixed FindObject so that if searched object contains a dot in the name, it will seek for it as a full object name instead of any object with matching name.
  • (11/11/19) Added Actor.FindSpot native function that seeks for empty space for a box extent space (same way as bCollideWhenPlacing works).

  • (11/11/19) Changed 'if' conditions to compile as coerce parms to easily allow cast them into bool comparisions.
  • (11/11/19) Changed bool operators to also take coerce parameters.
  • (11/11/19) Fixed a compiler bug where when it would compile a sub expression it would automatically truncate float into int, as example: int i = (1.f/10.f)*100.f would compile as int(int(1.f/10.f)*100.f), thus resulting in value 0.
  • (11/11/19) Fixed ConsoleCommands to properly handle multi-parameter exec functions, if using multiple string parameters then they will be split by spaces, unless they are enclosed with quotation marks or apostrophes.
  • (11/11/19) Made return value from exec function return to ConsoleCommand output.
  • (11/11/19) Made if first parameter of exec function is "PlayerPawn Caller", then that will be set to the PlayerPawn executing the command (or None if ran on any other Actor).
  • (11/11/19) Made ExecFunctionStr work same way as ConsoleCommand with parameters.
  • (11/11/19) Added functions to LevelInfo: static native final function PlayerPawn GetLocalPlayerPawn() / static native final function LevelInfo GetLevelInfo() - To easily find active PlayerPawn and Level in the game.
  • (11/11/19) Added variables to LevelInfo: RealTimeSeconds (actual TimeSeconds unmodified by TimeDilation), NetTimeSeconds (network synced between server and client TimeSeconds, only for 227j clients and when LevelInfo.bNetworkTimeSeconds is true), LastDeltaTime (current frame DeltaTime), LastRealDeltaTime (current frame DeltaTime unmodified by TimeDilation).
  • (11/11/19) Added Actor.bTickRealTime to allow Actor tick by real DeltaTime unmodified by TimeDilation.

  • (11/11/19) Added parms to Actor.Spawn: SpawnInstigator/SpawnTemplate/bNoCollisionFail from prevous SpawnAct function.
  • (11/11/19) Added new parm to Actor.SetTimer: CallbackObject: To call the timer function on any external object.
  • (11/11/19) Made defaultproperties importer detect if same variable is imported multiple times (and throw compiler warnings).
  • (11/11/19) Added feature to allow defaultproperties with numeric values contain math evaluations in them, ex: Health=Nali.Health*2 or SomeFlag=(1 << 3)
  • (11/11/19) Added support for simple preprocessed maths in script code (encompassed with {}), as example: Health+={Nali.Health/2}, which will compile as Health+=20;

  • (11/11/19) Added new parm to Canvas.DrawTile, vector WorldPosition, to make it draw the tile as a sprite in level.
  • (11/28/19) Added Actor.CollisionGroups and Actor.CollisionFlag which can be used to let modders set custom collision rules.
  • (11/28/19) Added function bool Actor.IsBlockedBy( Actor Other ) to check if another actor can block that actor.
  • (11/28/19) Added Pawn.bShovePawns (and Pawn.ShoveCollisionRadius to specify internal radius) which if enabled, allows pawns to push back other pawns (kinda like Team Fortress style) depending on their mass differences.
  • (11/28/19) Added function GameInfo.AllSavedGames to grab a list of all savegame slots used along with their information.
  • (11/28/19) Exposed Object ObjectIndex to unrealscript and added function Object.FindObjectIndex to find an object by its index.

  • (10/19/21) Made ScriptCompiler merge any string constants and solve any 'Chr(XX)' constant functions (as example Chr(13)$Chr(10) will compile into "\r\n").
  • (10/19/21) Also made ScriptCompiler solve any constant math equations it finds (as example float(Asc("A")/2.f) -> 32.5).
  • (10/19/21) Made LoadPackageContents only load objects of specified type user desired so it doesn't actually load entire package if you for example load only sound FX.
  • (10/19/21) Added a special hack to LoadPackageContents so it's only allowed to load music objects from zxFire (Zora's map-pack music) package (as apperently it includes entire Fire.u contents from 224v).
  • (10/19/21) Added legacy mod support for mods that used SpawnAct function.

  • (10/19/21) Added 'IsValid' function syntax to check if optional out parameter has been specified, otherwise it'll cause an Accessed none ScriptWarning when accessing it.
  • (10/19/21) Added "const reference" support for UnrealScript as const out parameter, which works like a pointer but will create a temporary copy of the variable if you pass in a r-value.

  • (02/23/22) Fixed Script compiler from crashing on specific compiler errors.
  • (02/23/22) Added a shortcut ClearZ function to Canvas.
  • (02/23/22) Added variable modifier 'repnotify' which will make client callback OnRepNotify event when received from server.
  • (02/23/22) Added variable modifier 'norepnotify' which tells client to not call PostNetReceive event if that value was changed.
  • (02/23/22) Made Actor.BecomeViewTarget to get called client-side too (called by C++ codes when client receives a new ViewTarget from server).
  • (02/23/22) Fixed a compiler error when you tried to use AllObject(Class'Class') iterator.
  • (02/23/22) Added new line extent size parameter to Actor.DrawDebugLine to draw an axis aligned box along line.

  • (02/23/22) Fixed an UnrealScript crash where if a function returns a struct that contains dynamic arrays or string components and the function caller doesn't assign the value to anything (this will produce a new OpCode unique to 227j, so any mods compiled with such conditions wont be usable on pre-227j).
  • (02/23/22) Added a compiler error if you try to compile a class with 2 replication blocks.
  • (02/23/22) Added function modifiers 'reliable'/'unreliable' 'server'/'client' to have compiler add those functions directly to replication blocks, can even be used to override a replication polarity in a child class ('client' modifier also makes function simulated).
  • (02/23/22) Added another function modifier 'nonetwork' to disable a replicated function from being replicated in a child class.
  • (02/23/22) Added Object PlayerInteraction class which can be assigned to a player to override player input/movement/render.

      • Advanced options property listing.
    • And new web pages:
      • File upload (for simple mod uploading).
      • Advanced options.
      • Web admin accounts manager.
    • Misc features/improvements:
      • Fixed problem where sometimes messaging spectator wouldn't spawn, thus didn't allow for viewing chat log.
      • Added webadmin privilege levels for accounts (0-minimum, 255-maximum privileges).
      • Added DoS connection detection (to block off users that rapidly try to connect to webadmin with different passwords).
  • (12/16/19) Fixed UCC.exe Server commandlet to accept command input.
  • (03/24/21) Fixed WarlordRockets spawning smoke and SeekingRockets spawning decals on servers.
  • (03/24/21) Made clients verify cache files GUID version before using them.
  • (03/24/21) Added server command: UVerifyClient <ID> to manually verify a single or all clients packages with HASH values to verify they are in network sync.
  • (03/24/21) Fixed GameInfo to not send game options to clients when switching levels.
  • (05/29/22) Increased maximum MaxClientRate value to 1,000,000.

Optimizations

  • (12/04/12) Altered many of Engine classes to use TouchingActors iterator instead of the Touching list array for better results and fewer bugs.
  • (11/11/19) Optimized Real crouching code.
  • (11/11/19) Optimized serverside networking code.
  • (11/11/19) Made vectors better compressed over network between 227j+ clients only.
  • (11/11/19) Made all meshes animations lookup use a mapped hash value instead of an array lookup for a huge performance boost in animation lookup code.
  • (11/11/19) Made Actor shadows use multi-threading for rendering it.
  • (11/11/19) Optimized and improved dynamic zones.
  • (11/11/19) Added a projector feature (Projector.bBuildStaticMap) to make it generate pre-rendered model for BSP and bStatic StaticMeshes for a huge performance boost with MapProjectors.

Bug Fixes

  • (11/11/19) Fixed server to remember what variables has been networked when a bNoDelete actor becomes network irrelevant and then relevant again.
  • (11/11/19) Fixed a security flaw with networking which clients could abuse to leak memory on server.
  • (11/11/19) Fixed a division by zero error with BigRock.
  • (11/11/19) Improved stability with decals and projectors on save/load games.
  • (11/11/19) Fixed a bug with TcpLink and UdpLink which would make it shut down socket twice upon destroy (thus throwing a windows warning).
  • (11/11/19) Fixed SunlightCoronas from shining through static meshes (and optimized it).
  • (11/11/19) Fixed weather emitter particles to also hit static meshes.

New in-game features

  • (02/20/13) Added NoRunAway option into Unreal.ini [Core.System] to enable old crash behavior with RunAwayLimit, to help modders in developing and debugging.
  • (03/03/13) New commands:
    • CacheRip <package>: Rips a specific package
    • CacheRipAll: Rips all packages from the server you are currently in.
    • CacheRipMap: Rips current map and dependencies. In order to avoid confusion, it just grabs the info from the server and uses it to rip the stuff from local cache directory. No server overhead is produced.
      Note that determining the file extension correctly is only working on 227 servers, older servers don't provide the information needed. This way only maps can be identified, any other file will get the extension .u - which will work for Unreal but the disadvantage of that is obvious.
  • (07/20/16) added a new option ContinuousKeyEvents as a client setting to enable old behavior to continue running when typing
  • (07/20/16) New supported prefixes for URL sharing via game chat:

  • (11/11/19) Fixed LevelInfo.bCheckWalkSurfaces to work. It will make Texture.Friction scale Pawns walking friction (if you use Friction 10, it will function as a ladder texture, similar to Half-Life).

v469 backports

  • (06/13/21) Ported over from network fixes: if packet loss prevented channel from closing it will be resent, made channels open in a sequential order to prevent client->server RPC call from switching actor refs on parms incase actor happens to get destroyed inbetween.
  • (10/19/21) Backported fixed Pawn walk along ledges code.
  • (10/19/21) Pulled some render buffer overflow handling code to fix some specific render crashes.

  • (06/08/22) Fixed various DirectDraw issues on Win10/11.
  • (06/08/22) Added InhibitWindowsHotkeys option to UWindowsClient. If set to its default value of FALSE, the game no longer blocks the Alt+Esc, Alt+Tab, Ctrl+Esc, and Ctrl+Tab hotkeys. Setting the option to TRUE restores the original UE1 behavior.
  • (06/08/22) Removed SlowVideoBuffering from UWindowsClient because this option no longer works on Win7+
  • (06/08/22) Made the DirectInput mouse handling code read the full DIMOUSESTATE2

  • (06/08/22) Disabled EnhancedPointerPrecision by default, except in Unreal Editor
  • (06/08/22) Fixed several bugs that broke mouse input in Unreal Editor if you had raw input enabled in-game
  • (06/08/22) Fixed a bug that could cause GetClipboardText to read invalid data from the clipboard
  • (06/08/22) Made UWindowsViewport::ShutdownAfterError send a WM_FORCEMINIMIZE to the viewport window. This fixes a bug where the viewport remains visible if the game crashes with raw input active
  • (06/08/22) Made lighting rebuilds use a minimal null renderer (WinDrv.TemporaryRenderDevice). This should speed up lighting rebuilds
  • (06/08/22) Fixed several bugs that caused raw input not to capture the mouse correctly when switching between windowed and fullscreen mode

Linux

  • (03/29/13) Fixed Linux: relaunch command.
  • (05/17/13) Cleaned up OpenAL to work better with OpenALSoft in Linux, changed some bad coding, improved EFX error handling. Maybe will fix some of the problems in windows people experienced with non CreativeLabs cards as well.
  • (02/19/15) In order to fix some old crappy problems and missing abilities in Linux, added SDL2Drv and SDL2Launch for Linux. In order to do that all old SDL stuff becomes deprecated and won't make it into 227j: SDLDrv, SDLLaunch, SDLGLDrv, SDLSoftDrv. That's nothing to worry about though, since these have been kept mostly as reference and have no features which could be compared to OpenGLDrv, which can be used in any Linux distro with at least Mesa. Details can be found here: http://www.oldunreal.com/cgi-bin/yabb2/YaBB.pl?num=1424370983/0#0
    • In the stats page changed the order from V / U to U / V

  • (02/23/22) Fixed a Linux server crash when map contained a PathNode route reference to itself.
  • (02/23/22) Made Object.Rand function limit number to 15-bits for Linux (so Titan boulders don't spin with an insane speed).
  • (05/29/22) SDL2Drv added support for RefreshRate
