GZDoom 4.11.0

Highlights

• Several new languages: Danish, Norwegian, Swedish and Turkish
• cleanup of Doom's and Chex Quest's small font to use proper character heights for international support.
• extended all fonts to be capable of handling all European languages which are in common use.
• First stage of DSDHacked support. Tested only with crusader.wad for now.
• The build system was transitioned to optionally use vcpkg, which allows building GZDoom on Windows by running a single batch file.
• WebP and QOI support for textures.
• sanitized the light mode selection to make it a first class mapping feature by separating map dependent light mode setup from performance related user preferences for the default setting.
• Linux: GTK startup now offers all the options of the Windows variant
• lots of new ZScript features.

Bugfixes

• screen size settings are now properly saved.
• fix UMAPINFO boss action clearing.
• MBF21's BOSS flag now implies NORADIUSDMG.
• remove memory leak in A_ChangeModel
• fix OpenGL ES selection on the windows startup dialog

Details

• Changed the variable type of Crossed3DWater. Seems like there was some kind of oversight. Crossed3DWater is an F3DFloor pointer, not sector_t.
• Add ZScript constants used by FallAndSink
• Switch to miniz from zlib
• fix for Genesis of Descent E1M2, which is impossible to complete on ITYTD/HNTR. I had to decompile the ACS script to figure out what was going on, basically at one point you get locked into a room and have to kill exactly 3 enemies with TID 215 for the door to unlock. One of these is a Baron tagged for only Medium and Hard, in his place is an Imp #1184 that has all the right script setups but is not set to appear on any difficulty. The fix is to simply have this imp appear on Easy.
• fixed the overlapping sector handler in hw_fakeflat.cpp. This picked the wrong plane as the proper texture cutoff.
• fixed: The UDMF loader did not adjust the floor/ceiling overlap state after processing UDMF sector plane properties.
• fixed: EV_DoDonut checked the wrong compatibility variable and missed all map specified flags.
• Fix gameinfo load from same directory as file containing gameinfo lump
• validate partner seg index in LoadGLZSegs before using it
• added compatibility handler for Phocas Island 2 MAP01.
• fixed doublebind check with automap. For the automap C_DoKey gets called twice, once with the automap bindings and once with the regular bindings and doubleclicks.
• clear the Dehacked string table after passing it to GStrings. For some reason std::move does not work here so make sure it won't stick around.
• stop all cutscenes before the ENDOOM screen.
• fixed: Boom's generalized crushers must stop 8 units above the floor. This required changing the special, so a new one was added to avoid altering Generic_Crusher.
• Fix a very rare crash with complex Polyobjects
• add support for not localizing some text functions, and modify menu text fields to use this
• let Dehacked set the implicit missile flags.
• fix ammo consumption of powered up Phoenix Rod.
• add unexplored secret color for overlay automap to the menu
• made all FileReader implementations 64 bit capable.
• added a nomirrors compatibility handler and applied it to Conf256's CONF55 map. This is for disabling broken plane reflection setups.
• When compat_floormove is enabled prevent sector floor from lowering if a thing is stuck in the ceiling (vanilla behavior)
• fixed M_GetSavegamesPath for Linux.
• Add Inventory::ModifyBob and Inventory::ModifyBob3D
• Expose OF_Transient to actors as bNoSaveGame
• add StartGameDirect function
• fixed: MBF21's BOSS flag implies NORADIUSDMG.
• fixed: For Dehacked, A_CPosAttack needs to use a hard coded attack sound. This discrepancy is ancient, so the approach used for the shotgunner does not work here and some hacks are needed to remap the function only for Dehacked.
• implemented the remaining dynamic structures of dsdhacked
• dsdhacked: Allow dynamic creation of new actors
• dsdhacked: allow dynamic creation of new states.
• add float.equal_epsilon and double.equal_epsilon
• Allow building gzdoom with Vulkan with either X11 or Wayland WSI integration through CMake options
• use stb-image for JPEG decoding because the old library provides no advantage over it.
• Allow disabling colors for NameAllKeys
• avoid high stack usage in anmtexture.cpp
• added DSDA's passover/nopassover keys to the MAPINFO parser.
• use a string pool to store all filenames and in the file system. this avoid lots of small allocations for data that will released in bulk later.
• use the lump cache directly for FileData. This was the final puzzle piece to allow using memory mapped files in the future.
• use better hash function in the file system. This is djb2 which is supposedly one of the best string hashing functions around.
• rewrote dir CCMD using ScanDirectory and avoiding I_ChDir entirely.
• use ScanDirectory in all places where the findfile API was used.
• WebP image support
• added safeguards against very early access to console variables in Cocoa backend
• Add support for QOI image formats
• block the centerview CCMD if the player has TOTALLYFROZEN. This is deliberately done this way, instead of placing the check inside PlayerPawn::CheckPitch, because there may be other situations where we don't want to block the centering function (APowerFlight::EndEffect being one such case)
• replaced zstrformat with stb_sprintf.
• A_Chase CHF_DONTLOOKALLAROUND
• Add Weapon::ModifyBobLayer , Weapon::ModifyBobLayer3D and Weapon::ModifyBobPivotLayer3D
• allow explicit casts between vectors of different underlying types
• Fixed BlockingLine giving erroneous results
• add CountSectorTags/CountSectorTags/CountLineIDs/GetLineID
• Exported reflection functionality. Localized reflection code to a single function. Fixed an error where NOSHIELDREFLECT was being checked on the wrong Actor. Fixed an oversight where MIRRORREFLECT was checking for valid target despite not needing one.
• Added ShadowAimFactor and ShadowPenaltyFactor. These properties allow to specify how much an actors' aim is degraded when shooting at a shadow actor. And how much the shadow actor itself affects the shooters' aim, respectively.
• Added MF9_SHADOWAIMVERT. This flag causes the vertical aiming of monsters to also be affected when they aim at shadow actors.
• Added MF9_SHADOWBLOCK. Actors in the line of fire with this flag trigger the MF_SHADOW aiming penalty. The shooter needs to have MF9_DOSHADOWBLOCK to check for actors with this flag.
• Added MF9_SHADOWAIM. This flag allows actors with MF6_SEEINVISIBLE to still get an aim penalty by trying to shoot at a shadow actor.
• Added damage property to earthquakes.
• Added damage and thrust multipliers to quakes.
• Added QF_DAMAGEFALLOFF. This flag makes it so that the damage and actor thrusting of earthquakes fades with distance like the screen shake effect does.
• Added (XF/RADF)_CIRCULAR. This flag makes explosions use a spherical radius, instead of a cubic one. Only took almost 30 years.
• Added (XF/RADF)_NOALLIES. This flag allows explosions to not harm any actors that are friendly to its' source.
• Added (XF/RADF)_THRUSTLESS. This flag allows for explosions that do not thrust any of the actors caught in the blast.
• Allow custom MessageBox menu selector
• Individual Joystick Enable/Disable Toggles
• add QualifiedName to VMFunction and allocate these static names from the class data memory arena instead of using FStrings.
• null pointer type checks in the VM added to avoid crash on bad codegen.
• Expanded Service's Get functions to pass in name parameter.
• Added GetName(UI/Data) to Service class.
• make all legacy light modes except 'Doom' and the software rendering emulation MAPINFO only. A CVAR still exists for testing but its value won't be saved to the config.
• MAPINFO can not enforce any of the two software light modes, as low end users require the option to change this to the 'performance' setting.
• changed lightmode menu options: user can only select between "performance', 'software' and 'vanilla'. 'performance' is the old 'Doom' mode which is still needed to speed things up on low end hardware.
• fix the ammocount parameter in Weapon.CheckAmmo
• fix UMAPINFO boss action clearing. This did not handle the case where the actions were cleared without adding new ones and also did not clear the MBF21 boss action flags.
• remove memory leak in A_ChangeModel
• made some changes to vectors.h so that it can be used without the floating point function replacements.
• Add Voodoo Zombie Compatflag
• remove vid_gpuswitch and all its handling; it is only as of now useful in old versions of Windows 7/8/10 which are no longer supported
• added MaxEffectTics field to Powerup
• adapted font system to properly handle Turkish. Those i's are really messy, especially when dealing with allcaps or pure lowercase fonts.
• made D_WriteUserInfoStrings memory safe.
• Fix TArray allocating 0 bytes in constructor
• Add dynamic lights to software slope drawer
• use uniform buffers for dynamic lights everywhere. Branching on SSBO content does not work that well on NVidia so it is better disabled. So far only implemented for OpenGL Vulkan needs more work.
• Fix Software Slope Rendering for non-1.2 pixel ratios
• add the flags MINVISIBLE and MVISBLOCKED
• Extend pseudo-generics system used by maps to dynarrays
• add RedirectCVAR directive for loading alternate maps based on a Bool CVAR setting
• Fixes bones when using OpenGL 3.3 (UBO bone data)
• validate the buffer size in HWViewpointBuffer::Set2D.
• Fixed a bug where calling an invalid virtual function would cause a crash.
• Add cvars to sprite shadows progressively according to thing <-> floor distance
• Added OnEngineInitialize() for static event handlers
• cleanup of the Doom and Chex Quest small fonts' discritical characters
  ...

• Fix checking of wrong variable in String..Float concatenation
• Clearscoped getters for map data
• CustomMessageBox
• fix colormap remapping when colormap entries may have fullbright entries which should not be considered duplicates
• stop all sound before showing ENDOOM.
• disabled shortcutting the intermission code if no summary screen is wanted. This also disabled all cutscenes being attached to the completed map.
• added 'foreach' loop to ZScript.
• implementation of Quaternion type in ZScript
• GLES: Added IQM bone support.
• SendConsoleEvent function for EventHandlers
• Future-proof particles by resetting them completely when replaced.
• added PlusZ intrinsic to Vector3 and ToVector intrinsic to numeric values. These just mirror features of the internal vector classes.
• added LengthSquared and Angle intrinsics for all vector types, also allow calling VectorAngle with a full vector as a single parameter.

• -noextras: disable loading of any extras (lights, brightmaps, widescreen)
• -nolights: disable loading of lights
• -nobrightmaps: disable loading of brightmaps
• -nowidescreen: disable loading of included widescreen assets
• fixed bad index check in CanWipe. This can be called with index == -1, which should check the first element of the intermission.
• GC: Have a real finalizer stage for destroying objects instead of mixing them in to the sweep stage.
• GC: Base GC rate on a running average of the allocation rate instead of basing it on the amount of time taken since the last sweep started.
• More GC stats for better tweaking.
• added characters U-0404 and U-0490 for Ukrainian language support.
• reworked all accented characters of Doom's SmallFont. Also adding a few new ones that were easy to do
• when converting to a portable install, flag the current session accordingly.
• changed CalculateBones to receive the bone component data directly instead of the owning actor.
• fixed FileExists check for -loadgame. This was done before the current savegame path was known so it always errored out.

GZDoom 4.9.0

Inportant note to Windows users:
GZDoom 4.9.0 changes where gzdoom.ini is stored. Unlike older versions this one will always prefer the system's user folder and place the INI in Documents/My Games/GZDoom if no INI is found. This was done to bring handling in line with current guidelines and to make it easier for commecial games that often get installed into a folder without write access. If you still want to store the INI in your game folder you have to create an empty file called GZDoom_portable.ini there before launching. If you still have an old INI in your folder, GZDoom will ask what to do with it, you can either move it to the user folder or convert to a portable install.

Change of savegame storage
This version introduces per-IWAD savegame folders. If you have old savegames you still intend to use, please wait with the update until you can safely delete them.

Highlights

• added PARAM_NULLCHECK to the block iterator creation functions.
• added [[noreturn]] to several functions that always throw exceptions.
• Particle Rolling
• Add Textured Particles
• Add GFF_NOEXTCHANGE to Phasing Zorcher flash. The Plasma Rifle does not light the player's sprite, so we must assume the Phasing Zorcher also should not.
• Fix HUD models not drawing if MODELDEF has been changed with A_ChangeModel
• Fix inconsistent distance and hit position on traces that skip everything.
• Fix canvas textures getting clipped by wrong scissor box
• Fix vulkan backend clearing the canvas textures to undefined contents

• added option to show hub and episode names on the alt HUD.
• reworked CVARs to not use a linked list and to be initialized manually.
• marked a few Printf calls in critical error paths as PRINT_NONOTIFY.
• fixed: R_LoadVoxelDef did not fully initialize the voxel descriptor it creates.
• don't crash on null pointers in V_GetFont.
• zero the velocity of crunched sprites. Since their size is zeroed, they are no longer subject to collision detection and may slide out of the level otherwise.
• don't crash when destroying incomplete textures. This can happen during TEXTURES parsing in case of an error.
• try to keep the engine stable for as long as possible if a VM exception occurs in OnDestroy while running a cleanup. This will still crash, but run long enough for the exception message to be visible.
• fixed F2DDrawer::SetClipRect.
• added vanilla donut handling to compat_floormove.
• Fixed: voxel models pitch/roll properties weren't initialized correctly
• Added QF_SHAKEONLY. The QF_SHAKEONLY flag changes the behavior of earthquakes with a damage radius, so that they only shake actors around, without also harming them.
• Added QF_AFFECTACTORS. The QF_AFFECTACTORS flag makes the thrusting and harming of damaging earthquakes also affect monsters. Monsters with DONTTHRUST will not be flung around by earthquakes.
• Added the QF_GROUNDONLY flag. The QF_GROUNDONLY flag makes earthquakes only shake the player while they are standing on the ground.
• fixed DrawLine commands by giving them a consistent floating point interface.
• heretic: e2m7 - missing texture
• fixed direct native interface for Draw(Thick)Line.
• fixed: The main loop never checked the cutscene flag for disabling wipes.
• Sync movie video playback to the audio, when possible
• Fix washed out colors in Vulkan HDR mode
• normalize the timer with the app start, not the epoch. This ensures smaller values and less wraparounds with integer values in scripts.
• un-deprecated the integer MSTime variant. Due to undefined downconversion rules from double to int, there is no way to safely downcast the return from MSTimef, meaning the function is completely useless for retrieving integral time stamps.
• added Harmony ENDOOM screen.
• added a config getter to the interface.
• moved language CVAR to backend.
• handle menu customization via callbacks.
• move hud scale CVARs to the backend.

GZDoom 4.8.0

Highlights
- added Raze-style HUD scaling. Not exposed in the menu yet, Set hud_oldscale to 0 and use shift with the screen resize keys to scale the status bar.
- handle the start/endoom screens with the ingame renderer. They are now present on all platforms and use the full screen size of the game.
- Many MBF21 fixes.
- added the cutscene system from Raze

Details
- the chat should use the console's scaling, not the one for the messages printed with the small font.
- fixed auto-scaling for console.
- removed all vid_fps offsetting. To compensate there is now also a "stat fps" which displays the FPS rate in the lower left corner. This had to go because unconditionally altering positions was causing problems with custom HUDs.
- added Raze-style HUD scaling. Not exposed in the menu yet, Set hud_oldscale to 0 and use shift with the screen resize keys to scale the status bar.
- added a few more names to the reserved names for main folder detection.
- consider "fonts" and "models" reserved folder names.
- fixed undefined behavior with Dehacked's value parser.
- Rebuild nodes for 1024.wad MAP02 to fix invisible obstacle near the exit area
- fixed fast crushers going out of sync if something is being crushed by them.
- fixed: Vulkan descriptor sets must check the real translation, not just the translation ID.
- handle the start/endoom screens with the ingame renderer.
- Create a MainWindow class that manages the main win32 window of the application
- Added Actor::LightLevel. Setting it to any value > -1 will override the sector's light level.
- Implement virtual Actor.FallAndSink for scriptable falling and water physics
- Added Actor.WaterDepth to retrieve how submerged and actor is, in map units
- added cutscene data parser. This covers: game start, episode start, cluster start/end, level start/end.
- MASTERNOSEE flag (#1601) Makes it so that if an actor's master is invisible due to camera/mirror/portal shenanigans, then the actor will also be invisible. Name based off of an Unreal Engine flag that does the exact same thing.
- Made CanCrossLine opt-in by requiring the CROSSLINECHECK flag.
- Added CanCrossLine virtual for actors.Called last after all other line checks occur. Returning false means the actor cannot cross that line.
- Add WorldOffset field. Adjusts the thing's 3D position on render side. This allows for adjusting a thing's visual position without impacting their hitbox.
- fix bad MP start spot in 1024.wad, MAP05
- Enables shortcuts for option menus. Press a key to immediately jump to the next option menu entry which starts with this key. Hold Alt to jump backwards.
- DontLightOthers: Acts as the inverse of DontLightSelf, where it won't light actors that aren't the owner.
- DontLightMap: The light doesn't affect the map.
- Relative Includes for ZScript
- remove m_filter and simplify related code
- exclude keys from ‚artifact‘ cheats
- fixed MF_SHADOW handling for MBF21. This needs to alter the render style as well.
- fixed handling of automap sprites with negative scale.

- Allow SendNetworkEvent during title level.
- add sv_ammofactor to change the skill adjustment for ammo
- extended the read buffer for the 'secret' CCMD.
- This is merely preparation - the actual loading is still in one uninterrupted piece.
- Fix that vk_debug doesn't output anything for newer versions of the vulkan sdk
- added JPEG YCCK decoding.
- Added MF8_SEEFRIENDLYMONSTERS. Non-friendly monsters with this flag on will be able to attack friendly monsters on sight.
- fixed mouse coordinate checks for Strife conversations. ypositions needs one entry per response, not one per line.
- fixed radius of BossBrain actor
- Added QF_3D flag for quakes. When used, the quake thinker will perform a 3D distance check instead of 2D.
- removed compat_soundcutoff from the menu. Handling for this was removed 14 years ago when ZDoom transitioned to FModEx 4.x
- add -compatmode for setting a compatibility mode on startup as a replacement for +compatmode not working as intended.
- activate Hungarian in the menu
- Fix off-by-one in Vulkan multisample sample count selection
- completed Hungarian translation.
- Fix co-op softlock in Heretic E4M8 due to multiplayer teleporter.
- added handlers to load Strife’s startup screen images as textures
- added image source handlers for Hexen’s special startup image types
- use the hex font for the Heretic/Endoom text screens.
- fixed setup of files to load on startup.
- fixed return type of MSTimeF script function.
- moved -rngseed init to D_InitGame
- pass ´hashfile´ to filesystem as parameter
- fix TArray::Append with rvalue parameter. This must clear the source array to obey move rules.

- only check „allowduplicates“ for the final file system init
- added missing BLOCKF_ flags for ZScript.
- added ‚repeat‘ option to SetLineActivation ACS function
- made friendlyseeblocks writable.
- removed all remains of the corpsegibs flag and made vileghosts interactive. Ghosts are still off by default, but they will now be enabled when selecting the vanilla (strict) compatibility mode.
- restrict RealGibs for players only. All non-players will now always act as if the ‚corpsegibs‘ flag was set, regardless of the current setting.
- added Get/SetAmmoCapacity ZScript functions
- expose the ‚attenuatelights‘ map flag.
- added an option to delete a terrain type from a texture.
- add wipe transition support to the screenjob runner.
- migrated intermissions and summary screens to screenjobs.
- timer code fixes.
- added all the cutscene system from Raze
- added compat_nombf21 for cchest2.wad, map 19.
- Fix usage of -1 as OBJ model FrameIndex
- added zip64 handling
- added workaround to Dehacked so that „Doom“ only replaces the music name
- fixed some incorrect array allocation sizes in polyobj code
- added missing range check for scrolling down an option menu with the mouse wheel.
- do not clamp warped textures.
- disabled deletion of previous event handlers when using 'eventhandler' keyword in MAPINFO.
- fixed: decal things failed to spawn their decals on 3D floors.
- validate the index argument for GetSavegame and abort if out of range.

GZDoom g4.7.1

Mainly a bugfix release addressing the following issues:

• Fixed: SBar_DrawTextureRotated was missing the angle parameter
• Compat patch for misplaced items in Hexen MAP08.
• fixed some imprecisions in font luminosity calculation. This was still going through the palette which could result in off-by-one errors.
• fixed palette initialization for single lump fonts (FON2 and BMF)
• push sprite shadows a little back for distance sorting
• avoid multiple Dehacked mappings to the same function to fix MBF21 lookup issues.
• disallow changing the line spacing for option menus.
• be a bit more aggressive with the GC when not running the game loop.
• fixed memory leak in DShape2DBufferInfo.
• allow "INDEXFON" as an alias for "INDEXFONT".
• fixed A_Punch having a short attack range (take 2).
• GLES: Fix texture MapBuffer and AllocateBuffer create client side memory.
• Fix "out of memory" errors when the vulkan backend is asked to create zero byte sized buffers
• resolved a VM abort upon morphing while the tome of power is active
• fixed particle processing in the main thinker loop. This may not be guarded by the dynamic light flags, only the light ticking may.
• fixed handling of states with the 'light' keyword.
• Fixed broken V_BreakLines.
• treat "materials" as a known folder name for eliminating root folders in Zips.

New Features:

• widescreen assets for all officially supported games. This version adds Hacx, Harmony and Chex Quest.
• Allow WorldUnloaded events to know the next map name (if any).
• Allow map markers to scale relative to automap zoom.
• Add cvars to control automap line alpha and thickness
• PreTravelled virtual for player and inventory.
• Allow customization of pause screen.
• ReadThisMenu / MenuDelegate overriding.

GZDoom g4.7.0

The major new addition is a new GLES2 backend, meant to improve performance on low end hardware. This was written by emile_b for the Android port but backported to the mainline for old hardware support.
Please note that this backend removes some non-essential features to increase performance, like the entire postprocessing or advanced lighting features like specular or PBR.
Our tests show no performance gains on modern hardware capable of Vulkan, so is not recommended to run it on such systems - it is solely meant for old hardware that have performance issues with the modern GL backend.
On older hardware capable of supporting OpenGL 3.3 our measurements show that performance is generally on par with LZDoom.

Furthermore, to make the new backend available to 32 bit users as well, GZDoom 4.7 will exceptionally provide a 32 bit build as well, but please be aware that it depends on the survey's result whether this will see continued maintenance, as user share was already extremely low two years ago.

The survey has been re-enabled for this version so that we can get some information about how the state of systems being used for GZDoom has developed over the last two year. This is mainly due to the addition of the new GLES backend for old hardware, so we can get an overview of how much of this hardware still exists and how future support needs to be handled. We would like to ask as many users as possible to participate, so that we can make the right decisions based on the information we obtain. Like previous surveys this does not collect any private information - all it sends is basic info about the operating system, the number of CPU cores, the name of the graphics card and supported OpenGL/Vulkan versions.

Highlights:

• Widescreen graphics for Strife
• new GLES backend for better performance on OpenGL 3.3 and early 4.x hardware.

GZDoom 4.6.1

• Fixed bug with BishopPuff moving in wrong direction

• a couple important widepix fixes

• fix for "Return to Phobos (return01.wad) has an ancient bug in map E1M2 where the switch to raise the exit bridge doesn't work in versions of Doom past patch 1.2."

• add missing break statement in level_compatibility.zs

• fix DaggerAlert using FindState incorrectly.

• Fixed wrong parameter type passed into TryMove here

• fixed: Actors did not set the position when spawning a dynamic light.

• Add 'AddDialogues' in MAPINFO to additively add Strife NPC dialogs without overwriting each other.

• let dynamic lights call UpdateLocation instead of just setting their position right after being spawned. This ensures that the position is correct and that everything gets set up properly.

• fixed parsing of MAPxx par times in BEX lumps

• Make sprite shadows ignore float bob

• fixed explosive damage radius for clericflame.

• fixed permission validation in OptionMenuItemCommand.DoCommand. This was missing the InMenu check like the other critical menu functions.

• added detection of macOS 12 Monterey

• prevent redundant string copying in Strife conversation parser

• Fixed impassable exit line in 007ltsd.wad E4M7

• fixed initialization of model frames

• fix missing border flat on heretic shareware

• fixed parsing of 2D vectors in OBJ model loader

• added TVector2<> constructor from float*

• fixed bad type in FxFontCast.

• fixed potential crash when sound sequence is destroyed. Level can be unset if sound sequence destruction happens after saved game loading failure

• report correct macOS version with older SDKs

• Add Windows 11 detection

• added an OnDestroy method to Shape2D so that its users can explicitly free the data it holds. In this case it is very important to care about management, because this class will hold GPU-side buffers!

• prevent appearance of dangling pointers in corpse queue

• fixed format specifier compilation warnings

• fixed: splashes need the MOVEWITHSECTOR flag.

• better sprite shadow control

  • exclude sprites which are not either opaque or use regular blended translucency from casting shadows.
  • exclude wall and flat sprites from casting shadows.

  In both of these cases the shadow math is unable to produce anything useful that doesn't look off.

• fixed: shadow alpha for translucent objects was not correct in the hardware renderer.

• tweaked shadow code a bit.

  • let CASTSPRITESHADOW act as an override for render style checks. If this is set we can assume that a shadow is desired regardless of style.
  • reordered code to do the more costly checks only when needed.

• fixed brightmap definitions for the SpiderMastermind.

• add player setup to simple options menu

• do not precache unreferenced textures

• added map option to disable shadowmaps. (Prompted by 'Hurt' which has > 4000 lights and runs into both performance issues and unpredictable light selection for the limited amount of shadowmap slots.)

• language update
