Installation

The latest release is always at https://github.com/sauerbraten/p1xbraten/releases/latest.

Windows

Download and run p1xbraten_setup_<version>.exe from the link above. p1xbraten will be installed alongside your existing Sauerbraten installation.

macOS

Download macos.zip from the link above, open your Downloads folder in Finder and double-click the zip file to extract it.
Navigate into sauerbraten.app
Open a second Finder window
Go to Applications, right click Sauerbraten.app, select "Show Package Contents"
Make a copy of Contents/MacOS/ (in case you want to go back to the vanilla client in the future)
Drag the Contents folder from the zip file into the Finder window, merging it with the existing folder and replacing any existing files.
Open a Terminal and type chmod +x (note the space at the end), then drag the p1xbraten_x86_64_client file from Finder into the Terminal window
When it says chmod +x [...]/Contents/MacOS/p1xbraten_x86_64_client, press Enter to execute
In Finder, right click start_protected_game_x86-64.app, select "Show Package Contents", go into Contents, then into MacOS
In the terminal, type chmod +x again, then drag the start_protected_game file from Finder into the Terminal window
When it says chmod +x [...]/Contents/MacOS/start_protected_game_x86-64.app/Contents/MacOS/start_protected_game, press Enter to execute

If this seems like a lot of work that's because it is. I blame Apple.

Linux

Download and extract linux.zip from the link above and put its contents into your Sauerbraten directory, then chmod +x bin_unix/p1xbraten_x86_64_client bin_unix/start_protected_game. Use p1xbraten.sh/anticheat.sh to launch.

Patches

a.k.a. Features

upstreamed to SVN

"fixes" nextfollow to start at the first/last player when cycling forwards/backwards, instead of second or second to last respectively
allows using Ctrl-Left/Right (Option on Mac) to jump over words in the console input
allows using Ctrl-Backspace/Delete (Option on Mac) to delete entire words in the console input
improves player name matching in setmaster, setteam, ignore, kick, spectator, follow and goto commands: after the normal full matching, (if parseplayer>0) the argument is tried to be matched as a case-insensitive prefix, then a case-insensitive substring of a player's name

moviehud.patch

adds namesabovehead toggle: when 0, hides the names above players' models (usually rendered as particle text), while keeping status icons for health boost, armor and quad

scoreboard.patch

enables suicide and detailed, per-weapon damage recording

Note that suicide and damage recording is only accurate in games you observed from the beginning. When you join a running game, all previous damage is unknown, and suicides are only initialized from negative frag counts.
cleans up the scoreboard look (for example, right-justifies numeric scoreboard columns)
adds scoreboard toggles:
- showflags: when 1, shows the number of flags scored by a player; always hidden in non-flag modes
- showsuicides: when 1, shows how often each player suicided
- showkpd: when 1, shows each player's frags/death ratio
- showaccuracy: when 1, shows each player's overall accuracy
- showdamage: when 1, shows each player's overall damage dealt; when 2, shows each player's overall net damage (= dealt - received); always hidden in insta modes
- showdamagereceived: when 1, shows each player's damage received
makes the following built-in cubescript commands take an optional player CN as argument:
- getfrags
- getflags
- getdeaths
- getaccuracy
- gettotaldamage
- gettotalshots
- getweapon
Omitting the argument will return the information about hudplayer, i.e. yourself (if playing) or the player you're currently spectating.
adds damage-related cubescript commands:
- getdamagepotential (same as gettotalshots when not filtering by weapon)
- getdamagedealt (same as gettotaldamage when not filtering by weapon)
- getdamagereceived
- getdamagewasted (= potential − dealt)
- getnetdamage (= dealt − received)
All of the new damage-related commands (as well as getaccuracy) default to showing hudplayer's stats across all weapons. However, they all take two optional integer arguments to query stats of a certain player and optionally for a specific weapon: /<cmd> [cn] [weapon] (use -1 as CN to query specific weapon stats about hudplayer).

To show comed-like statistics in the lower right corner, copy the following into your autoexec.cfg:
```
gamehud = [
  format "^f7SG: ^f1%1%% ^f7CG: ^f1%2%% ^f7RL: ^f1%3%% ^f7RI: ^f1%4%% ^f7GL: ^f1%5%% ^n^f7frags: ^f0%6 ^f7deaths: ^f3%7 ^f7acc: ^f2%8%% ^f7kpd: ^f5%9" (
    round (getaccuracy -1 1) 0.1                    )(
    round (getaccuracy -1 2) 0.1                    )(
    round (getaccuracy -1 3) 0.1                    )(
    round (getaccuracy -1 4) 0.1                    )(
    round (getaccuracy -1 5) 0.1                    )(
    getfrags                                        )(
    getdeaths                                       )(
    round (getaccuracy) 0.1                         )(
    round (divf (getfrags) (max (getdeaths) 1)) 0.1	)
]
```

Use /usep1xbratenmenus 0 to use the default scoreboard.

hudfragmessages.patch

enables frag messages showing the weapon used to complete the frag (on by default)
adds the following variables:
- hudfragmessages: 0 disables all frag messages, 1 enables them for all modes, 2 enables them for non-insta modes only
- maxhudfragmessages: how many messages to show at most (between 1 and 10)
- hudfragmessageduration: how long each message will be shown, in seconds, between 0 and 10
- hudfragmessagefade: 0 or 1: whether or not to fade out messages
- hudfragmessagex: horizontal position (between 0.0 and 1.0) where messages will appear
- hudfragmessagey: vertical position (between 0.0 and 1.0) where the newest message will appear
- hudfragmessagescale: size of the messages, between 0.0 and 1.0
- hudfragmessagestackdir: direction in which to stack old messages: -1 to stack upwards, 1 to stack downwards, 0 to stack towards the closes edge of the screen depending on hudfragmessagey
- hudfragmessagefilter: bitfield filter var (like confilter), e.g. 0x3800 shows all players' frags, suicides, and teamkills
- hudfragmessageforcecolors: when 1 (default), uses colored names, even in non-team modes

You can easily configure the hud frag messages using the improved menu (options → hud → adjust hud frag messages).

fullconsole.patch

removes the guiskin background of fullconsole in favor of a gradient background on the left
improves interplay of scoreboard and fullconsole
fullconsize is deprecated and unused, instead the console always takes up all available space
adds fullconalpha var: sets the opacity of fullconsole's left edge in percent (from 1 to 100)

hudscore.patch

hides hudscore when there is just one team/player

serverbrowser.patch

styles the serverbrowser to be consistent with the cleaned up scoreboard
divides 'players' column into 'players' and 'slots'
right-justifies ping, players, slots, and port columns
adds the serverbrowsershow[ping|players|slots|mode|map|time|master|host|port|description] variables: set to 0 to hide the respective column from the UI
adds the filterservers string variable to only show servers in the serverbrowser whose mode, map or description matches (using case-insensitive substring matching)

The p1xbraten menu gives you a simple search field on the serverbrowser using this variable. Use /p1xbratenmenus 0 to use the default serverbrowser.

listteams.patch

adds listteams command that returns a list of names of non-empty teams (according to filters) when two or more teams exist and an empty string otherwise (listteams [includeself?] [includebots?] [includespecs?])
extends listclients command to allow omitting spectators and only listing clients of a certain team (listclients [includeself?] [includebots?] [includespecs?] [teamname?])

The updated menu includes a better master menu thanks to these changes:

tex_commands.patch

adds settex <id> command to apply a texture by ID

decouple_framedrawing.patch

removes fps-induced limiting of the main loop (for example, input & network processing were affected by maxfps)
introduce maxtps var to limit the main loop independently from maxfps (for example to save power): 0 to disable limiting (default), 100..1000 to set how many ticks per second are allowed; maxfps overrides maxtps if maxfps > maxtps

This patch allows using maxfps without compromising on the frequency of input polling and network event processing. In vanilla Sauerbraten, maxfps limits the whole game's main loop. This patch removes the main loop limiting and instead skips only frame drawing until a new frame is needed, but still processes network events and player input on every main loop iteration.

While vanilla Sauerbraten is truly unlimited after /maxfps 0, p1xbraten's mainloop can additionally be limited using the maxtps variable. Setting maxfps to any value other than 0 also forces a maximum tick frequency of 1000 (but respects lower settings), even if you set maxtps 0, so that p1xbraten can prioritise frame draw timing. Set both maxfps and maxtps to 0 to get vanilla's unlimited behavior back.

Using maxfps and maxtps, you can optimize for different goals:

for lowest average latency, use /maxtps 0 and /vsync 0
for lowest consistent latency, use /maxfps 0, /vsync 0, and set maxtps to the highest value that gives you a stable fps counter on your system
to use fewer resources and save laptop battery, use /maxfps 0, and set maxtps to the lowest value that gives you smooth graphics

crosshaircolor.patch

adds crosshaircolor variable to set a base crosshair color (for example, /crosshaircolor 0 255 0 for pleasant green)

zenmode.patch

adds zenmode variable: if 1, hides non-essential console messages:
- server messages
- chat and team chat messages from spectators
- joins (all), leaves and renames (of spectators)

gamehud.patch

properly right-justifies gamehud, wallclock, showfps, and/or showfpsrange lines
adds a useful playerlist showing who's alive vs. dead when spectating in the lower right corner
adds isdead <cn> command to check if a player is currently dead (only works when you are spectating)

chat_highlight_words.patch

lets you define words that trigger a sound when they appear in chat or team chat
adds addchathighlightword <word> command (for example, put addchathighlightword pix and addchathighlightword p1x into autoexec.cfg to receive a highlight on both spellings)
adds chathighlightsound variable to set the sound to play (default: free/itempick)

modversion.patch

adds the p1xbratenversion variable (read-only): contains the version of your installation as a string
adds the getclientp1xbratenversion <cn> command: returns the version of p1xbraten the player is running
adds the enablep1xbratendetection variable: set to 0 to disable broadcasting your p1xbraten version (and detecting other p1xbraten players yourself)

This lets you see wether a player connected to the same server as you is using p1xbraten, and what version. It relies on p1xbraten clients sending additional packets to the server, which the server then broadcasts to all other clients. This means other players can tell you're using p1xbraten (and what version). No information other than "I use p1xbraten, version X.Y.Z" is sent. No information is sent to me (p1x) or any third party. Opt out if you are firefly!

For an overview of who uses p1xbraten, you can run /showgui p1xbratenusage.

minimizedframes.patch

adds the minimizedframes toggle: when 1, frames will always be drawn, even when they would usually be skipped because p1xbraten is minimized

hasflag.patch

adds the hasflag <cn> command: returns 1 if the specfied player carries a flag

playerspeed.patch

adds the playerspeed variable (read-only): returns the hud player's speed (in units per second)

up_down_hover.patch

adds the up, down and hover movement commands:
- up/down induce movement up or down relative to the player's view
- hover prevents any change in height from forward/backward movement and making up and down work along the world's Z axis
all three commands only work while editing or spectating

paused_spec_movement.patch

enables free movement as spectator while the game is paused

clientdemo.patch

adds the recordclientdemo <0|2> command: 0 is the same as stopclientdemo; 2 starts recording a demo immediately
adds the stopclientdemo command: stops an ongoing demo recording

Client-side demos record the game as you experience it, and work independently of server-side demo recording. They also work locally, without being connected to any server. Your own position, movement and view is recorded at 125 frames per second.

colored_weapon_trails.patch

adds the trailcolor[shotgun|chaingun|rocketlauncher|rifle|grenadelauncher|pistol] vars that change the respective weapon's projectile/particle trail
adds the settrailcolor <SG|CG|RL|RI|GL|PI> <color> command (for convenience: changing the variables directly also works)

You can also adjust the trail colors in the options menu.

crosshairreloadfade.patch

adds crosshairreloadfade variable: set to 0 to disable the "crosshair-goes-dark-while-weapon-reloads" effect

better_console.patch

adds name completion to chat console (press Tab)

Name completion tries old-style prefix matching first, then will also try substring matching to suggest more names. In addition to vanilla's matching at the end of the line, it also works in the middle of the input, as long as the cursor is placed in front of a space character.

If you want to keep using Tab to complete commands in the chat prompt (without explicitly typing '/' at the beginning), use this bind:

bind "T" [inputcommand "" "" "" "c"] // instead of saycommand

Also, you can put the following into your autoexec.cfg for cleaner command prompts (replace the keys to your liking):

bind "SLASH"     [inputcommand "" [$commandbuf] "/" "cx"]
bind "BACKQUOTE" [inputcommand "" [$commandbuf] "/" "cx"]
bind "CARET"     [inputcommand "" [$commandbuf] "/" "cx"] // BACKQUOTE on German keyboards
bind "BACKSLASH" [inputcommand "" [servcmd $commandbuf] "#"] // works for #commands on zeromod, spaghetti, and remod
bind "HASH"      [inputcommand "" [servcmd $commandbuf] "#"] // only works with German keyboard layout

nextfollowteam.patch

adds the nextfollowteam command that will cycle through players grouped by team and falls back to vanilla's nextfollow in non-team modes (which just iterates through CNs from low to high)

To use it, put the following lines into your autoexec.cfg (and remember you'll have to change them back to nextfollow before using the autoexec.cfg with other clients!):

specbind "MOUSE1" [nextfollowteam]
specbind "MOUSE2" [nextfollowteam -1]

anticheat.patch

Integrates Epic's Online Services SDK and Anti-Cheat framework to provide protected game sessions on p1xbraten anticheat servers.

adds the -e command line flag to enable anticheat support (anticheat launchers set this for you)
adds the anticheatenabled read-only variable (only available when using the anticheat launcher, and should never be 0)

setfont.patch

adds the setfont <name> command to set the UI font after registering the font using font <name> ... (setfont "default" to reset)

fullscreenmonitor.patch

adds the fullscreenmonitor variable: specifies on which display the game runs on when in fullscreen mode, 0 being the primary display
adds the getnummonitors command: returns the number of connected displays
adds the getmonitorname <id> command: returns the name of the monitor with the specified index

Server Patches

These are the patches that make p1x.pw different from other servers.

authservers.patch

adds addauthserver <key_domain> <hostname> <port> <privilege> server command to add an additional auth backend (other than the master server)

For example, you can put addauthserver "p1x.pw" "p1x.pw" 28787 "m" into your server-init.cfg to allow users registered with my master server to claim auth on your server.

serverlogging.patch

Improves logging when running a dedicated server:

adds logtime variable: if 1, all log messages are prepended with ISO date and time (e.g. [2021-04-06 17:12:05])
includes CN in connect, disconnect, chat, team chat log messages
logs a "join" message including CN and player name
logs map changes
logs all privilege changes

server_ogzs.patch

allows using slim .ogz files (see https://github.com/sauerbraten/genserverogz) on the server without getting checkmaps errors

managed_games.patch

adds the #competitive [MM[:SS]] remote command, that will (for the next match only):
- enable server demo recording and request client demo recording from p1xbraten users
- optionally, set the time to MM:SS
- wait for all players to have loaded the map before starting
- respawn all players on game start
- auto-pause the game when a player disconnects or goes to spec
- show a count down before resuming
- accept client demo uploads at intermission
- save all demo files of the match to disk
- not auto-load the next map
adds the #specmute remote variable: when 1, spectators can't send any chat messages (requires auth or admin)
adds the #tourney [MM:[SS]] remote command, which is the same as #competitive, but also enables specmute for the next match
adds the (admin-only) #do remote command to evaluate arbitrary cubescript on the server, for example #do persistteams 1, #do servermotd "happy fragging" or #do concat $serverauth

autoauthdomains.patch

adds the addautoauthdomain command to request an auth key automatically right after a player joined (not before joining; this won't let the player connect in private mode: only the server auth domain can be used for that!)

proxy_setip.patch

adds the addtrustedproxyip command to declare a packet source IP as belonging to a trusted proxy

This patch adds support for the SauerDuels proxy which can be used to obfuscate the IP of tournament servers. The setip protocol extension allows the proxy to forward the client's real IP, replacing the proxy's IP.

anticheat.patch

adds the -e command line flag to enable anticheat support
adds the forceanticheatclient toggle: if enabled, players are forced-to-spec on connect, and have to be using a p1xbraten anticheat client in order to play

serverbotbalanceearly.patch

adds the serverbotbalanceearly variable: if 1 (and serverbotbalance is also enabled), the server will equalize the player count of all teams by adding/reassigning/removing bots

This is a more aggressive form of auto-balance than vanilla's serverbotbalance, which only reassigns bots, and never adds or removes bots on its own. It's intended for public play and disables manually adding/removing bots.

bans.patch

adds the getip <cn> command to return a client's IP
adds the ban <ip> <minutes> command to ban an IP for the specified duration (or 30 minutes if not specified)
adds the unban <ip> command to remove any ban created earlier
adds the listbans command to list all currently active IP bans

All of these commands are admin-only. You can use these from cubescript or as a remote command (e.g. #listbans).

Project Structure

patches/ has all the patch files that turn vanilla Sauerbraten into p1xbraten
src/ has the p1xbraten source tree
Makefile has commands to work with the patches and an SVN checkout of vanilla
data/ contains p1xbraten specific cubescript files: each files exist as plain text .cfg file as well as gzipped, xxd'ed file for embedding during compilation
bin_unix/, bin64/, and sauerbraten.app/ contain OS-specific runtime dependencies
p1xbraten.bat and p1xbraten.sh are launch scripts for Windows/Linux
anticheat.bat/anticheat.sh launch p1xbraten with anti-cheat support enabled
server.sh, start.sh and start_anticheat.sh are my custom launch scripts (to facilitate launching the binary in this repo, but using content from ~/sauerbraten-code)

Building your own binary

You don't have to do this if you already followed the installation instructions above and just want to play!

Build dependencies

development headers of the ususal Sauerbraten build dependencies like libz, libSDL2[-image|-mixer]
libarchive-zip-perl / perl-Archive-Zip
development headers of libcurl (when checkupdate.patch is included and you're building targets other than linux64)

Building

On Linux or macOS, just run make install (given you installed the usual Sauerbraten dependencies). Building on Windows is not supported.

This will put the resulting binary into the usual place inside this repo. To use it, you have to copy it over to the same place in your actual Sauerbraten installation. On Linux, the start.sh script will launch the new binary from inside this repository, using the Sauerbraten files in $SAUER_DIR and ~/.p1xbraten as user data directory.

Using fresh upstream sources

You can build my client using fresh vanilla sources. Set $SAUER_DIR to the path of your Sauerbraten directory, then use make from-patches and make install:

export SAUER_DIR=~/sauerbraten-code
make from-patches
make install

A fresh source tree will be copied from the Sauerbraten directory, then all my patches are applied on top of that before buildling and installing a new binary.

Debugging

On Linux, I replace -O3 with -g -rdynamic in the Makefile, and exec with exec gdb --args in start.sh to set up debugging. Then:

make clean && make && make install
./start.sh

In gdb, typing run starts p1xbraten.
