Two bugs in the Opportunist bot strategy: 1. retreatMove: when a lone bot is surrounded by enemies with no nearby allies, all passable directions scored below the -1 initial threshold due to flat enemy penalties. Fixed by scoring distance-from-enemies as a positive value (further = better) instead of a flat penalty, ensuring the bot always picks the safest direction. 2. attackMove: BFS could never reach enemy targets because the passable function excluded all enemy positions. The target IS an enemy, so the path was unreachable. Fixed by wrapping passable to treat the target position as passable during attack pathfinding. All 19 tests now pass, including TestComputeMovesRetreat and TestComputeMovesNearbyAdvantageAttack. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |

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/app.html
Viewing Replays
- Open the web app at
http://localhost:3000/app.html - Navigate to "Replay Viewer" in the menu
- 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.
