This project allows you to use JRuby to control a Starcraft: Broodwar AI.
I will be using Windows Server 2012 on Azure to go through this guide. If you're on a different OS some steps might be slightly different.
You can buy it in the Battle.Net online shop. Unfortunately the default browser on Azure is so horribly configured that the shop won't work, so first use it to go to Firefox and download and install Firefox.
Then go to battle.net and follow their instructions. The game is under "Blizzard Classics"
Take not of the location of the game key, you will need it later.
The downloader will take a while, after which select "Install Starcraft". I recommend installing
Starcraft to C:\Users\<username>\Starcraft, this will help skip us some administration privilege
steps later.
You can download it here.
You can download it here.
Note that you have to select the "I agree to the terms" radiobutton above the download list before
you can click download. Make sure you pick the x86 option not the x64 option. We
need it to be 32-bit to cooperate nicely with Starcraft and BWAPI.
After installing it you will have to set your environment variables. Hit the windows key and type "environment" hit the down arrow key once to go to settings, and select one of the search results to go to the "Environment Variables" tool.
Under "System variables" click "new". Set the name to JAVA_HOME and the value to
C:\Program Files (x86)\Java\jdk1.8.0_74 or wherever you installed the JDK. Then select the PATH variable, click "edit"
and add at the end ;%JAVA_HOME%\bin. Don't forget the semi-colon.
To make sure you did it right, start up a powershell (windows key + "powershell" + enter) and then enter
java -version and hit enter. If everything went correctly Java it should say "Java HotSpot(VM) yadayada".
Download BWAPI from here.
Install it, again I suggest installing to C:\Users\<username>\BWAPI to avoid administrator privilege
hurdles.
After installation go to the BWAPI directory and in there to the ChaosLauncher directory and make a shortcut to the launcher on your desktop, you'll be using Chaos Launcher to run Starcraft.
While in the Chaos Launcher directory delete the file BWAPI_PluginInjectord.bwl (note the 'd' in there).
Then go to the folder you installed Starcraft in, then go to bwapi-data and open the bwapi.ini file in notepad.
Change the first two configurations to read:
ai = NULL
ai_dbg = NULL
Remember where this file is located, you'll want to set more configuration here later.
You can get it here.
Download and install the 32-bit version.
Go here and download and install the client here.
Now will be a good time to make sure you have a github account. After you got one go to the bwapi ruby example project.
Click 'Fork' to fork the repository to your account.
Launch the Github graphical UI and click the plus in the top left corner. Select 'clone' and then pick the project you just cloned. Leave the window open for the next step.
When it's done downloading right click the project name
and select 'Open Git shell'. Now you'll get a nice powershell. Run .\run.bat. If you did everything
correctly you'll see the text "Game table mapping not found" printed every few seconds. (Celebrate!)
Now startup Chaos Launcher (it might throw a few errors, disregard those) make sure only the "BWAPI Injector RELEASE" and "W-MODE" plugins are selected, and click "start".
Starcraft will be launched in a small window. Go through the game menus to create a player and launch a custom
game. When in the game you should see Playing as <player-name> - <race> in the top left and the workers
should go mine some minerals. That means the bot is working!
Read through bwapi_ruby.rb to see what classes I've defined for you. Check out the BWMirror documentation to explore the APIs available to you here.
Note that JRuby automatically exposes Ruby style accessors for everything, you'll be able to control Starcraft as if the API was written in Ruby. Read more about that here.
