BotBattle

An API driven bot battle for exploring AI development - inspired by vindinium

About

The purpose of the game is to create a bot that can outsmart the other players in a competition to navigate a grid of tiles and control the most gold resources for the most turns

Overview

• Each turn the players can make one move by posting their desired action to the game
• After all players have submitted their moves, the game is updated and the turn is advanced
  • If two players are on the same tile, they battle and both lose 20pts of health
  • If a player is on a heal tile, their health is restored by 20pts
  • If a player moves onto a gold tile, it is captured and their health is decreased by 20pts
  • Each player is awarded 1 point per gold tile they control at the end of the round
  • If a player's health falls below 1pt they are killed, losing all captured gold tiles, and restart at the nearest heal tile
• The players continue to make moves until the turn limit is reached at which point the player with the most points wins

Setup

Using Vagrant

1. Start vagrant

vagrant up

2. Create a deploy_resources/app.cfg based on deploy_resources/app.cfg.example

DB_HOST=db.hostname.com # <-- The hostname of your database (will be mapped to localhost in /etc/hosts)
DB_USER=battle_admin    # <-- The username to create in the DB
DB_PASS=db_password     # <-- The password to use for the created user

3. Create a src/public/api/config.php based on src/public/api/config.php.example

return [
    Config::DB_HOST => 'db.hostname.com', // <-- The hostname of your database (same as above)
    Config::DB_USER => 'battle_admin',    // <-- The username to access the DB (same as above)
    Config::DB_PASS => 'db_password'      // <-- The password to access the DB (same as above)
];

4. Run the application initialization script

cd /vagrant/deploy_resources
./app_bootstrap.sh

Note: You may need to run vagrant reload for everything to get up to date after the initial setup

1. PHP 7
2. MySQL
3. Composer

Steps

1. Create a user in your MySQL DB to use for the application
2. Load the database by running the initialization script: /vagrant/deploy_resources/db/init.sql
3. Create a src/public/api/config.php based on src/public/api/config.php.example

return [
    Config::DB_HOST => 'db.hostname.com', // <-- The hostname of your database
    Config::DB_USER => 'battle_admin',    // <-- The username to access the DB
