Showdown AI Competition

The Pokémon Showdown AI Client is a Node.js framework that enables developers to create artificial intelligence agents for the Pokémon Showdown battle simulator. It provides tools for interfacing with the game's protocol, simulating damage, and implementing decision-making logic for competitive Pokémon battles.

Key Features

• Battle Interface — Connects to Pokémon Showdown servers or runs offline simulations using the battle-engine.js library.
• Game State Management — Maintains a local approximation of battle state with hidden information handling.
• Damage Simulation — Includes a function to calculate projected damage for moves between Pokémon.
• Forward Model — Allows tree-search AI methods to simulate turns by supplying choices for both players.
• Data Tools — Provides access to comprehensive Pokémon, move, ability, and type data through helper functions.
• Agent Framework — Defines required methods like decide() and assumePokemon() for custom AI implementations.

Philosophy

The project abstracts the complexity of Pokémon Showdown's protocol to let developers focus on AI strategy, treating the battle state as an approximation that reflects the game's hidden information nature.
