Arxcode installing help
Arx - After the Reckoning is a big and very popular Evennia-based game. Arx is heavily roleplaying-centric, relying on game masters to drive the story. Technically it's maybe best described as "a MUSH, but with more coded systems". In August of 2018, the game's developer, Tehom, generously released the source code of Arx on github. This is a treasure-trove for developers wanting to pick ideas or even get a starting game to build on. These instructions are based on the Arx-code released as of Aug 12, 2018.
If you are not familiar with what Evennia is, you can read an introduction here.
It's not too hard to run Arx from the sources (of course you'll start with an empty database) but since part of Arx has grown organically, it doesn't follow standard Evennia paradigms everywhere. This page covers one take on installing and setting things up while making your new Arx-based game better match with the vanilla Evennia install.
Firstly, set aside a folder/directory on your drive for everything to follow.
You need to start by installing Evennia by following most of the Getting Started
Instructions for your OS. The difference is that you need to
git clone https://github.com/TehomCD/evennia.git instead of Evennia's repo because Arx uses TehomCD's older Evennia 0.8 fork, notably still using Python2. This detail is important if referring to newer Evennia documentation.
If you are new to Evennia it's highly recommended that you run through the
instructions in full - including initializing and starting a new empty game and connecting to it.
That way you can be sure Evennia works correctly as a base line. If you have trouble, make sure to
read the Troubleshooting instructions for your
operating system. You can also drop into our
or chat from the linked Discord Server.
After installing you should have a
virtualenv running and you should have the following file structure in your set-aside folder:
vienv/ evennia/ mygame/
mygame is the empty game you created during the Evennia install, with
evennia --init. Go to
that and run
evennia stop to make sure your empty game is not running. We'll instead let Evenna
run Arx, so in principle you could erase
mygame - but it could also be good to have a clean game
to compare to.
Clone the arxcode repo
Cd to the root of your directory and clone the released source code from github:
git clone https://github.com/Arx-Game/arxcode.git myarx
A new folder
myarx should appear next to the ones you already had. You could rename this to
something else if you want.
myarx. If you wonder about the structure of the game dir, you can read more about it here.
Clean up settings
Arx has split evennia's normal settings into
also has its own solution for managing 'secret' parts of the settings file. We'll keep most of Arx
way but remove the secret-handling and replace it with the normal Evennia method.
myarx/server/conf/ and open the file
settings.py in a text editor. The top part (within
"""...""") is just help text. Wipe everything underneath that and make it look like this instead
(don't forget to save):
from base_settings import * TELNET_PORTS =  SERVERNAME = "MyArx" GAME_SLOGAN = "The cool game" try: from server.conf.secret_settings import * except ImportError: print("secret_settings.py file not found or failed to import.")
Note: Indents and capitalization matter in Python. Make indents 4 spaces (not tabs) for your own sanity. If you want a starter on Python in Evennia, you can look here.
This will import Arx' base settings and override them with the Evennia-default telnet port and give the game a name. The slogan changes the sub-text shown under the name of your game in the website header. You can tweak these to your own liking later.
Next, create a new, empty file
secret_settings.py in the same location as the
This can just contain the following:
SECRET_KEY = "sefsefiwwj3 jnwidufhjw4545_oifej whewiu hwejfpoiwjrpw09&4er43233fwefwfw"
Replace the long random string with random ASCII characters of your own. The secret key should not be shared.
myarx/server/conf/base_settings.py in your text editor. We want to remove/comment out
all mentions of the
decouple package, which Evennia doesn't use (we use
hide away settings that should not be shared).
from decouple import config by adding a
# to the start of the line:
# from decouple import config. Then search for
config( in the file and comment out all lines where this is used.
Many of these are specific to the server environment where the original Arx runs, so is not that
relevant to us.
Install Arx dependencies
Arx has some further dependencies beyond vanilla Evennia. Start by
cd:ing to the root of your
If you run Linux or Mac: Edit
myarx/requirements.txtand comment out the line
pypiwin32==219- it's only needed on Windows and will give an error on other platforms.
Make sure your
virtualenv is active, then run
pip install -r requirements.txt
The needed Python packages will be installed for you.
Adding logs/ folder
The Arx repo does not contain the
myarx/server/logs/ folder Evennia expects for storing server
logs. This is simple to add:
# linux/mac mkdir server/logs # windows mkdir server\logs
Setting up the database and starting
myarx folder, run
This creates the database and will step through all database migrations needed.
If all goes well Evennia will now start up, running Arx! You can connect to it on
127.0.0.1 if your platform doesn't alias
4000 using a Telnet client.
Alternatively, you can use your web browser to browse to
http://localhost:4001 to see the game's
website and get to the web client.
When you log in you'll get the standard Evennia greeting (since the database is empty), but you can
help to see that it's indeed Arx that is running.
Additional Setup Steps
The first time you start Evennia after creating the database with the
evennia migrate step above,
it should create a few starting objects for you - your superuser account, which it will prompt you
to enter, a starting room (Limbo), and a character object for you. If for some reason this does not
occur, you may have to follow the steps below. For the first time Superuser login you may have to
run steps 7-8 and 10 to create and connect to your in-came Character.
- Login to the game website with your Superuser account.
- Press the
Adminbutton to get into the (Django-) Admin Interface.
- Navigate to the
- Add a new Account named for the new staffer. Use a place holder password and dummy e-mail address.
- Flag account as
Staffand apply the
Adminpermission group (This assumes you have already set up an Admin Group in Django).
- Add Tags named
- Log into the game using the web client (or a third-party telnet client) using your superuser account. Move to where you want the new staffer character to appear.
- In the game client, run
@create/drop <staffername>:typeclasses.characters.Character, where
<staffername>is usually the same name you used for the Staffer account you created in the Admin earlier (if you are creating a Character for your superuser, use your superuser account name). This creates a new in-game Character and places it in your current location.
- Have the new Admin player log into the game.
- Have the new Admin puppet the character with
- Have the new Admin change their password -
@password <old password> = <new password>.
Now that you have a Character and an Account object, there's a few additional things you may need to
do in order for some commands to function properly. You can either execute these as in-game commands
@ic (controlling your character object).
@py from web.character.models import RosterEntry;RosterEntry.objects.create(player=self.player, character=self)
@py from world.dominion.models import PlayerOrNpc, AssetOwner;dompc = PlayerOrNpc.objects.create(player = self.player);AssetOwner.objects.create(player=dompc)
Those steps will give you a 'RosterEntry', 'PlayerOrNpc', and 'AssetOwner' objects. RosterEntry explicitly connects a character and account object together, even while offline, and contains additional information about a character's current presence in game (such as which 'roster' they're in, if you choose to use an active roster of characters). PlayerOrNpc are more character extensions, as well as support for npcs with no in-game presence and just represented by a name which can be offscreen members of a character's family. It also allows for membership in Organizations. AssetOwner holds information about a character or organization's money and resources.
Alternate guide by Pax for installing on Windows
If for some reason you cannot use the Windows Subsystem for Linux (which would use instructions identical to the ones above), it's possible to get Evennia running under Anaconda for Windows. The process is a little bit trickier.
Make sure you have:
- Git for Windows https://git-scm.com/download/win
- Anaconda for Windows https://www.anaconda.com/distribution/
- VC++ Compiler for Python 2.7 http://aka.ms/vcpython27
conda update conda conda create -n arx python=2.7 source activate arx
Set up a convenient repository place for things.
cd ~ mkdir Source cd Source mkdir Arx cd Arx
Replace the SSH git clone links below with your own github forks. If you don't plan to change Evennia at all, you can use the evennia/evennia.git repo instead of a forked one.
Evennia is a package itself, so we want to install it and all of its prerequisites, after switching to the appropriately-tagged branch for Arxcode.
cd evennia git checkout tags/v0.7 -b arx-master pip install -e .
Arx has some dependencies of its own, so now we'll go install them As it is not a package, we'll use the normal requirements file.
cd ../arxcode pip install -r requirements.txt
The git repo doesn't include the empty log directory and Evennia is unhappy if you don't have it, so while still in the arxcode directory...
Now hit https://github.com/evennia/evennia/wiki/Arxcode-installing-help and change the setup stuff as in the 'Clean up settings' section.
Then we will create our default database...
...and do the first run. You need winpty because Windows does not have a TTY/PTY by default, and so the Python console input commands (used for prompts on first run) will fail and you will end up in an unhappy place. Future runs, you should not need winpty.
winpty ../evennia/bin/windows/evennia.bat start
Once this is done, you should have your Evennia server running Arxcode up on localhost at port 4000, and the webserver at http://localhost:4001/
And you are done! Huzzah!
