WASM Bot Builds

This directory contains the WebAssembly builds for the browser sandbox. Each bot compiles to a separate WASM module with the standard interface.

Bot WASM Interface

Each WASM module exports three functions:

// Initialize the bot with game config
bot.init(configJSON: string): string // {ok: bool, error?: string}

// Compute moves for the current turn
bot.compute_moves(stateJSON: string): string // moves JSON array

// Free result (no-op for Go/AS, required for interface compatibility)
bot.free_result(ptr: number): void

Directory Structure

wasm/bots/
├── gatherer/     # Go → WASM (energy-focused, avoids combat)
├── random/       # Go → WASM (random moves)
├── guardian/     # Go → WASM (defends own cores)
├── hunter/       # Go → WASM (hunts nearest enemy)
├── rusher/       # Rust → WASM (attacks enemy cores)
└── swarm/        # TypeScript/AssemblyScript → WASM (tight formations)

Building

Build all bots:

cd wasm/bots
make all

Build individual bot:

cd wasm/bots/gatherer
./build.sh

Output directory: wasm/dist/

Bot Sizes (estimated)

Bot Language Size
gatherer Go → WASM ~12 MB
random Go → WASM ~10 MB
guardian Go → WASM ~12 MB
hunter Go → WASM ~12 MB
rusher Rust → WASM ~3 MB
swarm AssemblyScript → WASM ~5 MB
