AI Code Battle

A competitive bot programming platform where participants write HTTP servers that control units on a grid world.

Overview

AI Code Battle is a game simulation platform where:

• Participants write bots in any language that expose HTTP endpoints
• Bots compete on a toroidal (wrapping) grid world
• Matches are executed offline and presented as completed replays
• A web platform shows leaderboards, match history, and replay viewers

Quick Start

Prerequisites

• Go 1.21+ (for game engine and CLI tools)
• Node.js 18+ (for web and worker components)
• Docker (for containerized deployment)

Running Locally

# Build CLI tools
go build ./cmd/acb-local
go build ./cmd/acb-mapgen

# Run a match between built-in bots
./acb-local -seed 42 -max-turns 100 -output replay.json -verbose

# Start web development server
cd web && npm install && npm run dev
# Open http://localhost:3000/

Viewing Replays

1. Open the web app at http://localhost:3000/
2. Navigate to "Replay Viewer" in the menu
3. Load a replay JSON file or enter a URL

Strategy Bots

Bot	Language	Strategy
RandomBot	Python	Random valid moves (baseline)
GathererBot	Go	Energy collection, avoid combat
RusherBot	Rust	Rush enemy cores aggressively
GuardianBot	PHP	Defend cores, cautious expansion
SwarmBot	TypeScript	Formation cohesion, group advance
HunterBot	Java	Target isolated enemies

Deployment

See DEPLOYMENT.md for detailed deployment instructions.

Quick Deploy

# Start all strategy bots
docker-compose -f docker-compose.bots.yml up -d

# Start match workers
docker-compose -f docker-compose.workers.yml up -d

Testing

# Go engine tests
go test ./engine/... -v

# Worker API tests
cd worker-api && npm test

# Index builder tests
cd cmd/acb-indexer && npm test

Architecture

The platform uses a split architecture:

• Cloudflare (free tier): Static site, API endpoints, D1 database, R2 storage
• Rackspace Spot: Match workers, bot containers, index builder

See docs/plan/plan.md for the full implementation plan.
