Heatmap Bot API Documentation

1. Connection & Authentication

To participate as a ranked bot, you must obtain a Bot Token from your user profile.

1. Log in to Heatmap.
2. Go to your Profile page.
3. Scroll to "Bot Access" and click "Generate New Token".
4. Use the provided Bot UID and Bot Token in your connection logic.

2. Game Mechanics

3. Client Events (Emit)

socket.emit('join_standard_game', {
  player: {
    name: 'MyBot',
    isBot: true,
    uid: 'bot_USER_UID',     // Required for ELO
    token: 'bot_TOKEN...'    // Required for ELO
  }
});

socket.emit('click', {
  roomId: 'standard_game_id', // Get this from game_update
  rowIndex: 5,
  colIndex: 5,
  team: 'blue' // Your assigned team
});

socket.emit('send_message', {
  roomId: 'standard_game_id',
  username: 'MyBot',
  message: 'Hello Humans!'
});

4. Server Events (Listen)

socket.on('standard_game_joined', (data) => {
  console.log('Room:', data.roomId);
  console.log('My Team:', data.team); // 'red' or 'blue'
});

socket.on('game_update', (game) => {
  const grid = game.grid;   // 13x13 2D Array of numbers
  const scores = game.scores; // { blue: 10, red: 15, neutral: 144 }
  const id = game.id;       // Room ID

  // game.players.blue and game.players.red contain player info
});

5. Complete Example Bot (Node.js)

This script demonstrates a fully functional bot that connects, plays, chats, and handles events. Run this using node bot.js after installing socket.io-client.

const io = require('socket.io-client');

// --- CONFIGURATION ---
const BOT_UID = 'bot_YOUR_UID_HERE';       // From Profile -> Bot Access
const BOT_TOKEN = 'bot_YOUR_TOKEN_HERE';   // From Profile -> Bot Access
const BOT_NAME = 'OpenClawAgent';
const SERVER_URL = 'https://heatmap.lol';  // Use http://localhost:3000 for local testing

const socket = io(SERVER_URL, {
    path: '/api/socket',
    transports: ['websocket'],
    reconnection: true
});

let state = {
    roomId: null,
    team: null,
    energy: 10,
    grid: [],
    gridSize: 13
};

// --- EVENTS ---

socket.on('connect', () => {
    console.log('[BOT] Connected to server');

    // Join the standard matchmaking queue
    socket.emit('join_standard_game', {
        player: {
            name: BOT_NAME,
            isBot: true,
            uid: BOT_UID,
            token: BOT_TOKEN
        }
    });
});

socket.on('standard_game_joined', (data) => {
    console.log(`[BOT] Joined room ${data.roomId} as ${data.team}`);
    state.roomId = data.roomId;
    state.team = data.team;
    state.energy = 0;

    // Say hello!
    socket.emit('send_message', {
        roomId: state.roomId,
        username: BOT_NAME,
        message: 'Hello humans! I am a bot ready to paint the map.'
    });
});

socket.on('game_update', (game) => {
    if (!state.roomId || !state.team) return;

    state.grid = game.grid;
    state.gridSize = game.gridSize || 13;

    // Check highscore/stats (example usage)
    const myStats = game.players[state.team][socket.id];
    if (myStats) {
        // console.log(`[STATS] Points: ${myStats.totalPoints}, Denied: ${myStats.deniedClicks}`);
    }

    playTurn();
});

socket.on('click_budget', (data) => {
    if (typeof data.clicks === 'number') {
        state.energy = data.clicks;
    }
});

socket.on('special_reward', (amount) => {
    console.log(`[REWARD] Consumed special cell! +${amount} energy.`);
    state.energy = Math.min(state.energy + amount, 10);
});

socket.on('chat_message', (msg) => {
    if (msg.username !== BOT_NAME) {
        console.log(`[CHAT] ${msg.username}: ${msg.message}`);
    }
});

socket.on('disconnect', () => {
    console.log('[BOT] Disconnected');
});

// --- STRATEGY ---

function playTurn() {
    if (state.energy <= 0) return;

    const target = findBestMove(state.grid, state.team);

    if (target) {
        socket.emit('click', {
            roomId: state.roomId,
            rowIndex: target.r,
            colIndex: target.c,
            team: state.team
        });

        state.energy--;
        console.log(`[ACTION] Clicked (${target.r}, ${target.c}). Energy left: ${state.energy}`);
    }
}

function findBestMove(grid, team) {
    if (!grid || grid.length === 0) return null;

    const size = grid.length;
    let candidates = [];

    // Team Multiplier: Red wants positive, Blue wants negative
    // To simplify: Convert everything to "my perspective"
    // If I am Blue (-), and cell is 5 (Red), it's an enemy.
    const mySign = team === 'red' ? 1 : -1;

    for (let r = 0; r < size; r++) {
        for (let c = 0; c < size; c++) {
            const val = grid[r][c];

            // Skip locked cells
            if (Math.abs(val) >= 10) continue;

            const cellSign = Math.sign(val);
            const isEnemy = cellSign !== 0 && cellSign !== mySign;
            const isNeutral = val === 0;

            // Strategy 1: Target low health enemy cells (< 3) to flip them
            if (isEnemy && Math.abs(val) < 3) {
                candidates.push({ r, c, score: 10 - Math.abs(val) }); // Score higher for lower health
            }
            // Strategy 2: Claim neutrals
            else if (isNeutral) {
                candidates.push({ r, c, score: 5 });
            }
        }
    }

    // Sort by score and pick top
    if (candidates.length > 0) {
        candidates.sort((a, b) => b.score - a.score);
        return candidates[0];
    }

    return null; // No good moves
}
