Pokemon battle bot

We developed a battle bot that you can play against on a public server, the bot can assume different strategies depending on your choice.

Basic playstyle

• MaxBasePower, the bot chooses the move with the best base power ignoring status moves, it switches to a random pokèmon only when one faints.
• BestDamage, the bot will choose the move with best damage, computed by taking into account many modifiers, and it will switch to the best pokémon in terms of type-matchup only when the current one faints.

Enhanced playstyle

• RuleBased, the bot acts based on hard-coded rules based on the matchup score between it and the opponent pokémon. This version can switch and use moves that can boost stats, set entry hazards and give a status condition.
• MiniMax, the bot acts on a minimax fashion by looking for some moves ahead in order to choose the best course of action.

How to challenge the bot

First, you need to create a registered account for the bot on the public server, then clone the repo

git clone https://github.com/nikodallanoce/PokeBOT

You also need to install all the required packages

pip install -r requirements.txt

After doing that, you can run the following command

python run_remote.py --user bot_username --password bot_password

If no username or password are passed, then the bot will try to retrieve such information from the environment variables BotAIF_username and BotAIF_password, if this doesn't work it will give an error.

Moreover, the command accepts some other arguments in order to change the bot's behaviour:

• You can choose how many challenges the bot will accept (default to 1) by using, as an example, --matches 10, once those matches are ended the bot will stop.
• As default the bot uses the rule-based player, you can use --player followed by the player acronym to change such thing.
  • MBP for the MaxBasePower player.
  • BD for the BestDamage player.
  • RB for the RuleBased player.
  • MM for the MiniMax player.
• You can see the bot status and infos at each turn by using --verbose.
• You can save the bot results in csv file by using --save, such file is then stored inside the bot_data directory.

Have fun playing with the bot.

Setting up a local server

If you want to run our bot, or your own, in a local server, then you can use the Dockerfile that you can find here inside the repo. First, copy the Dockerfile or clone the repo

git clone https://github.com/nikodallanoce/PokeBOT

Then modify the following lines inside the Dockerfile with the bot's username and password from the public server (you should have already registered the bot's account)

ENV BotAIF_username=your_bot_username
ENV BotAIF_password=your_bot_password

Create a new docker image and container, this should be done only once

docker run --name pokemoncontainer -p 8000:8000 -it pokemon

You can now start your container

docker start pokemoncontainer

The local server should be running and your container's logs should look like this

RESTORE CHATROOM: lobby
RESTORE CHATROOM: staff
Worker 1 now listening on 0.0.0.0:8000
Test your server at http://localhost:8000

If so, then everything is fine, you can test the various players against each other by using the following command

python run_local.py --matches 1000 --players BD RB

As for the run_remote.py, there are some more arguments available:

• You can choose how many matches to run concurrently by using --concurrency, the default value is 10.
• The results can be saved inside a csv file by using --save.

Keep in mind that --players expects a list of players acronyms, those are the same seen in How to challenge the bot.
