Introduction

BotArena is a sister project to my DeckBot project. Both projects use the same MTG engine to enforce rules, perform AI plays, retrieve card definitions etc. Unlike DeckBot, BotArena has a full graphical user interface with the following features:

• Rule enforced (both DeckBot and BotArena)
• Mana usage aware (both DeckBot and BotArena) which means the engine can automatically pass for you because you don't have enough mana to cast any spells or perform any abilities
• Play with computer (both DeckBot and BotArena)
• Play with another player over the net
• Deck constructions
• Define 'usage pattern' per ability per card to tell the application when not to ask you to play an ability (e.g. you only want to ping someone at the end of your opponent's turn)
• Drag and drop cards to perform single targeted operations (e.g. Shock, block an attacker)

The goal of BotArena and DeckBot is not so much about player vs player but about how to improve AI play with a computer player. As computers are getting more powerful, BotArena will get better automatically.

I have the following near term goals for BotArena

• Bug fixes
• 10th Edition additions (also for DeckBot)
• Multi-core CPU support for AI plays (also for DeckBot)

It is a work in progress. For more information, see also DeckBot.

MTG Card Images

Since all MTG images are copyrighted, BotArena doesn't include any MTG images. However, follow these steps to get BotArena up and running with resources on the web (download at your own risk):

1. To get MTG card images:
   1. Download MWS images:
      1. Go to http://www.mwsdata.com/forum/viewforum.php?f=4
      2. Follow the instructions outlined in the forum on how to get HQ images for MWS
      3. Currently you only need the following files:
         1. MWS+6E+Fulls.zip (or MWSHQ+6E+Fulls.zip if you can find it)
         2. MWSHQ+7E+Fulls.zip
         3. MWSHQ+8E+Fulls.zip
         4. MWSHQ+9E+Fulls.zip
         5. MWSHQ+10E+Fulls.zip
         6. MWSHQ+U+Fulls.zip
         7. MWSHQ+PLC+Fulls.zip
   2. Create a folder called 'MWS' under the '\Images\Cards' directory of your BotArena install directory and extract all the MWS files under it. You want to maintain the folder names to separate images in each edition:
      
   3. Download a good quality card back image. You can find one at: http://id.wikipedia.org/wiki/Magic:_The_Gathering
      1. Save the card back image file to \Program Files\BotArena\Images\Cards\CardBack.jpg
   4. For token images:
      Put token images under a \TK folder. You will need to do a little bit of renaming to get this to work. First identify the token image file. If you want to use a 1/1 Goblin token image (e.g. Goblin Warrens), you want to name the image file "Goblin1-1.full.jpg". BotArena will try to locate this file first. If this file is not found, it will try the name without the power-toughness, i.e. "Goblin.full.jpg". Since BotArena cover-up the power-toughness area of the image anyway, there is really no need to match the image's power/toughness with the token.
2. To get some nice wallpapers, try Wizards: http://www.wizards.com/magic/magazine/downloads.aspx?x=mtg/daily/downloads/wallpapers

Download

I no longer distribute BotArena. The download link is now disabled. The console/text-based DeckBot will continue to be available.

If this file is not found, it will try the name without the power-toughness, i.e. "Goblin.full.jpg".
