1. About

QuakeSpasm is a modern cross-platform Quake engine based on FitzQuake.

It includes support for 64 bit CPUs and custom music playback, a new

sound driver, some graphical niceities, and numerous bug-fixes and

other improvements.

Quakespasm utilizes SDL-1.2 or SDL2 frameworks, choose one which works

best for you. SDL2 has nicer features, smoother mouse input and better

support for newer operating systems, but no CD-ROM support.

2. Downloads

- Project Downloads: http://quakespasm.sourceforge.net/download.htm

- Latest code repository:

https://sourceforge.net/p/quakespasm/quakespasm/ci/master/tree/

- Github mirror:

https://github.com/sezero/quakespasm

3. Hints

Visit the FitzQuake homepage <https://celephais.net/fitzquake/> for a

full run-down of the engine's commands and variables.

- To disable some changes, use "quakespasm -fitz"

- Quakespasm's custom data is stored in "quakespasm.pak". Install

this file alongside your id1 directory to enable the custom console

background and other minor features.

- For different sound backend drivers use :

"SDL_AUDIODRIVER=DRIVER ./quakespasm"

where DRIVER may be alsa, dsp, pulse, esd ...

- Shift+Escape draws the Console.

- From the console, use UP to browse the command line history and TAB

to autocomplete command and map names.

- There is currently no CD Music volume support and SDL2 doesn't

support CD audio. cd_sdl.c needs replacing with cd_linux.c,

cd_bsd.c etc..

- In windows, alternative CD drives are accessible by

"quakespasm -cddev F" (for example)

- Quakespasm allows loading new games (mods) on the fly with

"game GAMENAME {-quoth/hipnotic/rogue}"

- Use "quakespasm -condebug" to save console log to "qconsole.log".

SDL2 builds no longer generate stdout.txt/stderr.txt.

Music Playback:

Quakespasm can play various external music formats, including MP3, OGG

and FLAC.

- Tracks should be named like "track02.ogg", "track03.ogg" ... (there

is no track01) and placed into "Quake/id1/music".

- Unix users may need some extra libraries installed: "libmad" or

"libmpg123" for MP3, and "libogg" and "libvorbis" for OGG.

- Use the "-noextmusic" option to disable this feature.

- As of 0.90.0, music is played back at 44100 Hz by default with no

need to adjust "-sndspeed".

- See Quakespasm-Music.txt for more details.

Controller Support:

The SDL2 variant of Quakespasm supports Xbox 360 style game

controllers.

The default configuration uses the left analog stick for movement and

the right for looking.

If your controller doesn't work you can try placing this file

https://raw.githubusercontent.com/gabomdq/SDL_GameControllerDB/master/gamecontrollerdb.txt

in your Quake directory, it is a community-maintained database that

adds support for more controllers to SDL2.

Controller Support - Cvars:

- joy_deadzone_look - Fraction of look stick travel to be deadzone,

between 0 and 1. Default is 0.175.

- joy_deadzone_move - Same as above, but for the move stick. Default

is 0.175.

- joy_deadzone_trigger - Fraction of trigger range required to

register a button press on the analog triggers, between 0 and 1.

Default 0.2.

- joy_outer_threshold_look - Outer deadzone for the look stick,

between 0 and 1. Default 0.02.

- joy_outer_threshold_move - Outer deadzone for the move stick,

between 0 and 1. Default 0.02.

- joy_sensitivity_yaw/pitch - Max angular speed in degrees/second

when looking. Defaults are 240 for yaw (turning left/right) and 130

for pitch (up/down).

- joy_exponent - For the look stick, the stick displacement (between

0 and 1) is raised to this power. Default is 2. A value of 1 would

give a linear relationship between stick displacement and fraction

of the maximum angular speed.

- joy_exponent_move - Same as joy_exponent but for the move stick.

Default is 2.

- joy_invert - Set to 1 to invert the vertical axis of the look

stick.

- joy_swapmovelook - Set to 1 to swap the left and right analog stick

functions. Default is 0, move on the left stick, look on the right

stick.

- joy_enable - Set to 0 to disable controller support. Default is 1.

Controller Support - Buttons:

Some of the controller buttons are hardcoded to allow navigating the

menu:

- Back - alias for TAB

- Start - alias for ESC

- DPad, analog sticks - mapped to arrow keys

- A Button - alias for ENTER in menus

- B Button - alias for ESC in menus

These buttons can be bound normally:

- LTRIGGER - Left trigger

- RTRIGGER - Right trigger

- LSHOULDER - Left shoulder button

- RSHOULDER - Right shoulder button

- LTHUMB - Clicking the left thumbstick

- RTHUMB - Clicking the right thumbstick

- ABUTTON

- BBUTTON

- XBUTTON

- YBUTTON

quakespasm.pak contains a default.cfg which has been updated to give

some default bindings. L/R shoulder buttons are bound to weapon

switching, and L/R triggers are jump and attack.

The controller support started as Jeremiah Sypult's implementation in

Quakespasm-Rift, and also uses ideas/code from LordHavoc's DarkPlaces.

4. Compiling and Installation

See the Downloads section to get the sourcecode, then below for

platform specific instructions. Quakespasm can also be built with the

cross-platform Codeblocks.

Quakespasm's (optional) custom data is now stored in the file

quakespasm.pak. This file should be placed alongside your quakespasm

binary and id1 directory.

Compiling for Linux/Unix:

After extracting the source tarball, "cd Quake" and edit the Makefile

for music options.

Streaming music playback requires "libmad" or "libmpg123" for MP3, and

"libogg" and "libvorbis" for OGG files.

Then type "make" to compile the program, and copy the "quakespasm"

binary (and "quakespasm.pak") to your Quake game directory.

Compile time options include

- make DO_USERDIRS=1 to include user directories support

- make DEBUG=1 for debugging

- make SDL_CONFIG=/PATH/TO/sdl-config for unusual SDL installations

- make USE_SDL2=1 to compile against SDL2 instead of SDL-1.2

Compiling for Windows:

QuakeSpasm developers cross-compile windows binaries using MinGW-w64

<http://mingw-w64.sf.net> and MinGW <https://mingw.osdn.io>. The

project can also be built using Microsoft Visual Studio 2005 and newer

versions.

Compiling for Mac OS X:

A Quakespasm App (including program launcher and update framework) can

be made using the Xcode template found in the MacOSX directory.

Alternatively, have a look at Makefile.darwin for more instructions on

building from a console.

Quake '2021 re-release':

QuakeSpasm 0.94 has support for playing the 2021 re-release content:

Copy the quakespasm binary to your rerelease installation and run as

you normally do.

- Revert "always run" changes from 0.85.9 and move the QuakeSpasm

customizations to a new "cl_alwaysrun" cvar: Set to 1 in order to

scale forward/side/up speed by "cl_movespeedkey" (usually 2), and

to make "speedkey" act as "slowkey".

- Change the "always run" menu option to offer three choices:

off (cl_alwaysrun 0, cl_forwardspeed 200, cl_backspeed 200)

vanilla (cl_alwaysrun 0, cl_forwardspeed 400, cl_backspeed 400)

- Updated some of the third-party libraries.

Changes in 0.92.0:

- SDL2 Game Controller support.

- Contrast support with new "contrast" cvar, behaving the same as

MarkV. It may be a useful alternative to the existing gamma control

for laptops in a bright environment, etc. Raising contrast gives

less of a gray/washed out look than raising gamma, but at a

disadvantage: colors near white get clipped to white.

- RMQ protocol (999) support, adapted from RMQEngine.

- Prevent a possible vulnerability in MSG_ReadString (old Q1/Q2 bug).

Visual improvements:

- New cvars r_lavaalpha, r_slimealpha, r_telealpha for fine-tuning

specific liquid opacities (from DirectQ/RMQEngine, non-archived,

default to 0), and new worldspawn keys _wateralpha, _lavaalpha,

_slimealpha, _telealpha, _skyfog (unique to Quakespasm, similar to

the behaviour of the "fog" worldspawn key).

- GLSL gamma is now supported on older hardware without NPOT

extension.

Interface improvements:

- New r_pos command to show player position.

- NaN detection in traceline with "developer 1" set now warns instead

of errors.

Code cleanup / Other:

- Update third-party libraries.

config.cfg.

- Default heapsize 256 MB (was 64 MB).

- Default zone 4 MB (was 384 KB).

- Raised MAX_SFX to 1024 (was 512).

Changes in 0.90.1:

Bugfixes:

- Fix dynamic light artifact where changing lightmap are rendered one

frame late (bug introduced in 0.90.0).

- Fix texture memory leak when changing video modes with SDL2.

- Fix a rare incorrect mdl lighting on 64-bit builds. (details here:

https://forums.insideqc.com/viewtopic.php?f=3&t=5620)

- Fix fullbrights turning black after "kill" command (bug introduced

in 0.90.0).

- Clear all fog values on map change to prevent colored fog carrying

- Allow loading saves with } character in quoted strings, fixes issue

with retrojam1_skacky.bsp.

- Fix viewmodel not lerping on extended-limit maps.

- Fix crash on out-of-bounds skin number.

Performance:

- Use multithreaded OpenGL on OS X for better performance.

- New, faster mdl renderer using GLSL. Disable with "-noglslalias".

Visual improvements:

- New gamma correction implementation using GLSL. Fixes all known

gamma issues (affecting the full display, persisting after

quitting, or darkening the screen on OS X). Disable with

"-noglslgamma".

- Use high-quality water by default (r_oldwater 0).

- Shadows use stencil buffer to avoid overlapping artifacts (from

MarkV.)

- r_noshadow_list cvar added (from MarkV.)

Interface improvements:

- Support pausing demo playback with the "pause" command.

- Autocompletion for "game", "record", "playdemo".

- Experimental windowed fullscreen mode available with

vid_desktopfullscreen 1 (only in SDL2 builds, takes effect upon

entering fullscreen mode the next time.)

- Silence "exceeded standard limit" messages unless developer cvar is

>= 1.

- Some spam moved from developer 1 to 2: "can't find tga/lit/ent",

"trying to load ent", "bad chunk length", "meshing",

"PR_AlocStringSlots: realloc'ing"

Code cleanup:

- Clean up IDE project files to build on fresh systems.

- Update 3rd-party libraries.

Changes in 0.90.0:

- Fix issues on Windows systems with DPI scaling.

- Unix/Mac user directories support. Disabled by default,

'make DO_USERDIRS=1' to enable it.

- SDL2 support. Disabled by default, 'make USE_SDL2=1' to enable it.

- Revised keyboard input code.

- Revised/improved the 'game' command, i.e. on-the-fly mod changing.

It now accepts an optional second argument for mission packs or

quoth support i.e. -hipnotic, -rogue, or -quoth. For example, for

WarpSpasm: "game warp -quoth"

- Command line: "-game {quoth/hipnotic/rogue}" is now treated the

same as -quoth, -hipnotic, or -rogue.

- Console speed now resolution-independent.

- Disabled gl_zfix, which caused glitches and is undesirable for new

maps. Replacement .ent files to fix z-fighting for several id1 maps

added to quakespasm.pak.

- PF_VarString buffer bumped to 1024, avoids truncated centerprints

from the 'In The Shadows' mod.

- Support for opengl non-power-of-two-textures extension (disable

compile-time options.

- Music and sfx now mixed at 44100 Hz to avoid downsampling music.

Low-pass filter applied to the sfx if -sndspeed is 11025 (the

default), to preserve the same sound quality as 0.85.9. New

-mixspeed option sets the rate for mixing sfx and music, and output

to the OS (default 44100), setting it to 11025 reverts to 0.85.9

behaviour. New snd_filterquality cvar, value can be between 1

(emulate OS X resampler) and 5 (emulate Windows resampler),

controls the sound of the low-pass filter.

- Better Hor+ field of view (FOV) scaling behavior.

- Better cross-map demo playback support.

- Fix screenshots when screen width isn't a multiple of 4.

- Fix a lighting glitch due to floating point precision.

- Fix a looping sounds glitch.

- Fix a vulnerability in file extension handling. Tighten path

handling safety.

- Initialize opengl with 24-bit depth buffer at 32 bpp.

- Reset all models upon gamedir changes. (Fixes failures with mods

using custom content.)

- Fix broken behavior upon gamedir changes if -basedir is specified

on the command line.

- NET_MAXMESSAGE and MAX_MSGLEN limits bumped to 64000.

- MAX_EFRAGS bumped to 4096, and MAX_CHANNELS to 1024.

- MAX_ENT_LEAFS bumped from 16 to 32 to work around disappearing or

flickering brush models in some situations. Also, if an entity is

visible from MAX_ENT_LEAFS or more leafs, we now always send it to

the client.

- Fix cvar cycle command not working sometimes.

- Host_Error upon missing models. (Prevents segmentation faults.)

- Change sv_aim default value to 1 (i.e. turn off autoaim)

- Add 'prev' and 'next' keywords to the 'cd' command.

- Work around a linux cdrom issue (playback might not start for a

while after a stop).

- Quakespasm content customization moved from engine-embedded into a

new optional quakespasm.pak file.

- Version bumped to 0.90.0 (because Quakespasm has a decent life of

it's own)

- Other fixes and clean-ups.

Changes in 0.85.9:

- Fixes for several undefined behaviors in C code (gcc-4.8 support.)

- Implemented Hor+ style field of view (FOV) scaling, useful for

widescreen resolutions. Configured by new cvar fov_adapt: set it to

1 and your fov will be scaled automatically according to the

resolution. Enabled by default.

- Adjusted string buffers for PR_ValueString and friends to fix

crashes with excessively long global strings seen in some rude

mods.

- Toned down warning messages from PF_VarString() a bit.

- Fixed Fitzquake's map existence check in changelevel (used to leak

file handles which would end up in a Sys_Error() due to consuming

all free handles if many maps reside not in pak files.)

- Fixes/cleanups in chat mode handling. Client no longer gets stuck

in chat mode upon disconnect.

- Mouse grab/key_dest fixes and key cleanups.

- The "speedkey" now acts as "slowkey" when "always run" is on.
