planet-wars-haskell

Unofficial Haskell starter package for the google ai contest.

What

The PlanetWars module contains a small library to build your bot on. The MyBot module contains a simple example bot, based on the example in the C++ starter package.

You should change the MyBot module to your liking. If you make any improvements to the PlanetWars module, I would appreciate if you have me pull your changes, so everyone can benefit from your improvements -- after all, we're trying to get the Haskell bots as high as possible in the ranking, right?

Building

You should be able to build your bot using:

ghc --make -O2 MyBot.hs

The server uses the -O2 flag as well. Now, you should have an executable called MyBot.

Running

Let's watch it fight against one of the java bots.

java -jar tools/PlayGame.jar maps/map7.txt 1000 1000 log.txt \
    "./MyBot" "java -jar example_bots/RandomBot.jar" | \
    java -jar tools/ShowGame.jar

planet-wars-haskell's Issues

Interpreted

Not sure why, but if I compile the Main.hs file, the PlayGame tool will work fine, but if I try:
java -jar tools/PlayGame.jar maps/map7.txt 1000 1000 log.txt "java -jar example_bots/RageBot.jar" "runhaskell /home/bana/haskell/planet-wars-haskell/Main.hs" | java -jar tools/ShowGame.jar
WARNING: player 2 timed out.
Turn 1
Player 1 Wins!

It seems to timeout. Maybe I'm missing something about how runhaskell handles stdin/stdout.

Vanishing of initial fleets.

In bot matches, I have found that the initial fleets simply vanish when they have reached their destination planet. For example, In this specific BugBot.hs, when you play the bot against itself in map7.
