There are some things you need to have for running TWCore:

1. Download a Java Development Kit (JDK).

   • If you are on a Linux distribution, download and install the appropriate package. This can usually be done through your distributions package manager.
   • If you are OS X then the JDK comes preinstalled and can likely be found at /System/Library/Java/JavaVirtualMachines; however, you can install a different version if desired.

2. Ant (Download Current Release of Ant, .zip archive) This may already be installed for your distribution. Try ant -version to check. Ant is a build tool commonly used in Java projects to compile source in an organized fashion. It operates on the build.xml file included in the project.

3. Subversion (SVN) This also may already be installed for your distribution. Try svn --version to check. SVN is version control software that allows for comparing code to previous or different versions.

4. (Access to) a Subspace zone. The easiest method is to host a zone locally for development.

Optional:

1. (Access to) a MySQL database.

Once you have your JDK downloaded and extracted you may need to point your $JAVA_HOME towards it.

1. Open up the file that declares your systems PATH variable. This will differ depending on your distribution but it might be /etc/bashrc, /etc/profile, ~/.bashrc or ~/.profile. It will look something like: export PATH=/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:$PATH
2. Add a line above the export PATH line and type export JAVA_HOME='/path/to/jdk' (The correct directory should contain a folder called bin with the java executable in it. Path to this executable would look like /path/to/jdk/bin/java, but don't include the /bin/java on the end when declaring JAVA_HOME.)
3. Save and close the file with the export JAVA_HOME in it. You'll need to then close and reopen your terminal or source the file. You can check to make sure you properly declared your JAVA_HOME with echo $JAVA_HOME, which should return /path/to/jdk.

In this step you will export the most recent TWCore version from the repository of twcore.org .

1. Navigate to the directory where you want the TWCore project to exist. (i.e. cd ~)
2. Type svn checkout -username <username> http://www.twcore.org/svn TWCore where <username> is your twcore.org username.
3. When it prompts you for a password, use your twcore.org password.

You can always update TWCore safely as it doesn't affect any running / binary files nor your configuration files.

Before you can use and configure TWCore, it needs to be built.

1. Navigate to TWCore/trunk/twcore, where you should see a file called build.xml.
2. Type ant -v with no additional parameters. This will build the project.

Note for building TWCore, TWCore must be turned off completely! Your configuration files will not be touched during the build process.

You must now configure TWCore so that it knows where your development zone is and what names you would like the bots to have. The configuration files include TWCore/trunk/twcore/bin/setup.cfg and various files in the TWCore/trunk/twcore/bin/corecfg directory. You can copy example files into the bin/ directory using ant configCopy in the TWCore/trunk/twcore directory.

1. Rename bin/setup.example.cfg to bin/setup.cfg
2. Open bin/setup.cfg and fill in the settings:

• [Server]
• Server should be set to the IP of the Subspace server you are connecting to
• Port should be set to the port of the Subspace server you are connecting to
• [Login Information]
• Main Login the name of the account for the TWCore Hubbot (e.g. MyHub)
• Main Password the password of the Continuum account for the TWCore Hubbot.
• Sysop Password the sysop password for the zone you are connecting to.
• (Optional) [Chat Names]
• Chat Name the default chat name of any bots that require it. Usually this is used to set to a chat used by the TWCore developers.
• Staff Chat the chat name of the staff chat.
• Smod Chat the chat of the smod/upper staff chat.
• (Optional) [Debugging]
• DebugOutput Set DebugOutput to 0 to turn stack traces off, 1 to turn them on. Stack traces are useful for debugging bots.
• [Directories]
• Core Location The complete path to your core (where build.xml exists). Do not end this with a slash. For example: C:\Subspace\TWCore (Windows) or /home/bots/twcore (Linux).
• (Optional) [Logging]
• Exception Log Set the file and path of the exception log. This log will contain any exceptions the bot runs into. For example: C:\Subspace\TWCore\exception.log or /home/bots/twcore/exception.log
• LogPrivateMessages Set LogPrivateMessages to 1 to have each bot record private messages in the /logs folder.

1. Rename all the example files in the bin/corecfg directory to .cfg. For example: autoload.example.cfg to autoload.cfg. Here is a short description of each configuration file:

• (Optional) autoload.cfg
• This is a list of bot types. All the bot types in this file will be automatically spawned when TWCore is started and connected to the Subspace server.
• operators.cfg
• This file provides startup permissions for specified users and defines how the bot auto-assigns privileges. You should put your name in here as an owner and put names of bot accounts you plan to use in the bots section (e.g. MyHub, MyBot1, MyBot2).
• (Optional) racism.cfg
• This file is a list of fragments that will be flagged by racism detection.
• sql.cfg
• This file contains the settings for working with a database. If you do not (want to) use a database, set ConnectionCount to 0. For more information, see below.

1. Configure sql.cfg (or just set ConnectionCount to 0):

• [General]
• RetryCount Amount of retries a connection is tried before it will be given up
• ConnectionCount Number of connections defined in this file and/or number of connections that are used. Set to 0 if you do not want to use a database.
• [Connection X] (Replace X for a number starting with 1, also with settings below)
• NameX Name of the connection. This same name is also used by the bots. The connection names used by the bots that come with TWCore are local, website and server.
• DriverX Name of the sql driver. This is usually set to com.mysql.jdbc.Driver which you don't need to change unless you want to work with a different type database then MySQL.
• LoginX The username used for connecting to the database server.
• PasswordX The password used for connecting to the database server.
• DataBaseX The database name that should be used. Make sure this database already exist on the server.
• ServerX
  The IP or the address of the database server. If the database is on the same machine, set it to localhost. If the database is not on this machine, make sure you have the database server configured that it allows external connections.
• PortX
  The port used to communicating with the database server. If you are using a MySQL server then you can leave it set to 3306.
• MinPoolSizeX
  The minimum number of connections required to be in the pool. You can leave the default set to 1.
• MaxPoolSizeX The maximum number of connections of the connection pool. You can leave the default set to 10.
• WaitIfBusyX Wait if the connection is busy. Can be set to 0 or 1.
  You can create several connections in this file, you only need to change the X in each setting to the respective connection number.

If you have followed the steps up to this point then you should be ready to run!

Make sure your development zone is running and any MySQL databases are accessible before trying to run.

You can recompile your source with ant which will make a bin/twcore.jar file. You could run this jar manually using java -jar bin/twcore.jar bin/setup.cfg or simply use ant run which will do this for you.

Your HubBot should then log into your development zone!

To spawn a bot you must edit a configuration file for the bot you want to spawn.

In TWCore we have two names for a specific bot: the bot type'' and the bot ''name.

The bot type is the name of the directory. The main .java and .cfg file within this directory both have the same name as the bot type. You use this bot type to specify which bot to spawn. The bot name is the name you configure inside the .cfg file.

To spawn a bot follow the following steps:

1. The first time you spawn a bot you have to rename the .example.cfg file in its specific directory to .cfg (e.g. src/twcore/bots/multibot/multibot.example.cfg).
2. Edit the .cfg file and specify the bot name and password. You can set the initial arena to 0 for a public arena if desired.
3. Start up TWCore if you haven't already.
4. PM !spawn <bottype> to your HubBot (e.g. !spawn multibot).
5. If the bot doesn't spawn into your zone, check the TWCore console for error messages.
