Revision as of 09:19, 12 August 2010





The armagetronad-ct branch comes from an attempt to build armagetronad trunk with scripting enabled. As I faced issues compiling or running it with ruby, and the underlying wrapper, swig, support most of the common scripting language, I started this branch to add an abstraction layer, and eventually, introduce other scripting language support.

At this time, we were switching our script from php to python, and I was unable to compile with ruby, so I've give Python a try ...

Armagetronad-ct is nothing but an experimental branch, as were armahacktron and sty+ct, based on armagetron trunk, currently being 0.3.x serie. Therefore, there are two major differences with sty+ct: - sty is not (yet) fully ported to 0.3.x serie and has not been included to this branch. So no flags, no balls, no zombies, no shooting... - although you can compile (still true?) trunk with zones v1 or v2, this branch has scripting support for zones v2 only...

Although this branch main target is dedicated server, it might be extended to some client side features. For example, you can define new chat command from scripting on server side. This might be extended to client side soon as it allows to build dynamic instant messages (ex: /hi [<playername>] to salute last entered or specified player(s).

Eventually, if some servers start using it and this branch becomes somehow useful, we might extend it to other languages as ruby, lua or php, or polish it enough to deserve to be merged in its right place: armagetron mainline.


We are working on linux only and there's no support for any other plateform. So here is a raw install procedure for debian/ubuntu users :

First, get armagetron dependencies: Check the following wiki pages, section "Building from sources".

Add extra dependencies for scripting. For python:

 sudo apt-get install python-dev swig

Get the branch:

 bzr co  lp:~armagetronad-ct/armagetronad/armagetronad-ct

Build with scripting enabled:

 cd armagetronad-ct
 ./configure --disable-etc --enable-python --disable-glout --prefix=/your/install/dir/here --enable-armathentication
     --enable-automakedefaults --disable-useradd --disable-initscripts
 make install

Running a server

The server expects to find scripting related files in a specific place: a subdirectory of armagetron data directory called "scripts". More precisely, it expects to find a file called File extension vary depending on scripting language. So far, as only python support exists, we'll assume we are working with python as during install part.

The first step will be to set up out server specific directory tree. Personaly, I like to keep all config, var, and scripts directory in one place for a specific server. So let's start by setting up our directory tree:


I'll assume you have include into the config subdir your config files.

So far, you'll have to copy the file generated by swig during compilation into the scripts directory. This file is located into the src/swig/ext subdir in you source file directory (the armagetronad-ct directory from install step). Eventually, this file must be copied with other required files into the installation data scripts subdirectory. In this case, this directory should be append in below. Warning, don't forget to update this file each time you reinstall/update your armagetronad-dedicated binary.

You'll have to create the scripts/ file and include a few lines in it:

 print("Start scripting initialization.")
 import sys
 import armagetronad
 # your code goes here
 print("End scripting initialization.")


Let's run it, taking care of setting the userdata directory

 /path/to/your/binary/armagetron-dedicated --userdatadir="/home/username/tron/servers/hello_scripting/"

Sample Scripts

You'll first have to load armagetronad module which also required to set path accordingly.

print("Start scripting initialization.")

import sys
import armagetronad

You might want to change some settings from scripting. There's 2 ways to achieve that. You can send a string as you can do from console:

armagetronad.ConfItem.load_all("CONSOLE_MESSAGE test line\n")
armagetronad.ConfItem.load_line("CONSOLE_MESSAGE test line 4\nCONSOLE_MESSAGE test line 5\nCONSOLE_MESSAGE test line 6")

You can also look for the corresponding setting item so you can use it as much as you want:

console_message_conf.set("Welcome from scripting ...\n")

You might want to react on game event. You can do it binding a procedure to a ladder log message.

def round_winner(args):
    print args
    print("PLAYER_MESSAGE "+p+' "Congratulation from script '+p+' !"')
    armagetronad.ConfItem.load_line("PLAYER_MESSAGE "+p+' "Congratulation from script '+p+' !"')
    ci = armagetronad.ConfItem.find("CYCLE_SPEED")
    print "cycle_speed " + ci.get()

def new_round(args):
    ci = armagetronad.ConfItem.find("CONSOLE_MESSAGE")
    for i in range(armagetronad.Team.num_teams()):
        ci.set("Team name: "
        for i in range(t.num_players()):
            ci.set("Player name: "


You might be able to define new command from scripting. The new command will be available from console within the game, from other console commands like DELAY_COMMAND.

def respawn_player(args):
    # first parse parameters: <player name> <message flag> <x> <y> <dirx> <diry>
    lst = args.split()
    player = armagetronad.Player.find_player(lst[0])
    flag   = int(lst[1])
    pos    = armagetronad.Coord(float(lst[2]), float(lst[3]))
    dirt   = armagetronad.Coord(float(lst[4]), float(lst[5]))
    armagetronad.Cycle.respawn_cycle(pos, dirt, player, flag)
respawn_player_conf = armagetronad.ConfItemScript("RESPAWN_PLAYER", respawn_player)
respawn_player_access_level = armagetronad.AccessLevelSetter(respawn_player_conf, armagetronad.tAccessLevel_Moderator)

You're now able to define chat commands. Here's an example :

def substitute(args): 
    lst = args.split() 
    print lst 
    p_out = armagetronad.Player.find_player(lst[1]) 
    p_in = armagetronad.Player.find_player(lst[2]) 
    if (not p_out.is_spectating()) and p_in.is_spectating(): 
        t = p_out.current_team() 
        print "can't substitute !" 

cc = armagetronad.ChatCommand("/substitute",substitute,armagetronad.tAccessLevel_Moderator)
