  Enabled: true
  ChannelId: "YOUR_CHANNEL_ID"
  MinecraftToDiscord: true
  DiscordToMinecraft: true
  Format: "**%displayname%:** %message%"

    DiscordRoleId: "123456789012345678"
    MinecraftPermission: "group.admin"
  vip:
    DiscordRoleId: "876543210987654321"
    MinecraftPermission: "group.vip"

Custom Bot Development

Node.js Example

const { Client, GatewayIntentBits } = require('discord.js');
const client = new Client({
  intents: [
    GatewayIntentBits.Guilds,
    GatewayIntentBits.GuildMessages,
    GatewayIntentBits.MessageContent
  ]
});

client.on('ready', () => {
  console.log(`Bot logged in as ${client.user.tag}`);
});

client.on('messageCreate', (message) => {
  if (message.content === '!serverstatus') {
    message.reply('Server is online with 20/100 players');
  }
});

client.login('YOUR_BOT_TOKEN');

Minecraft Plugin Integration

Create a simple plugin to communicate with your bot:

// Example plugin for bot communication
public class DiscordBridge extends JavaPlugin {
    @Override
    public void onEnable() {
        // Initialize HTTP client for bot communication
        setupBotConnection();
    }
    
    public void sendToDiscord(String message) {
        // Send message to Discord webhook or API
        postToBotAPI(message);
    }
}

Webhook Integration

Setting Up Webhooks

1. Create a Discord webhook in your channel
2. Copy the webhook URL
3. Configure your Minecraft plugin to use the webhook
4. Test the connection

Webhook Configuration

# Webhook settings
Webhooks:
  ServerEvents:
    Url: "https://discord.com/api/webhooks/YOUR_WEBHOOK"
    Events:
      - PlayerJoin
      - PlayerLeave
      - PlayerDeath
      - ServerStart
      - ServerStop

Automation Features

Player Join Notifications

// Automated player join message
@EventHandler
public void onPlayerJoin(PlayerJoinEvent event) {
    String message = String.format(
        "🎮 %s has joined the server! (%d/%d players online)",
        event.getPlayer().getName(),
        Bukkit.getOnlinePlayers().size(),
        Bukkit.getMaxPlayers()
    );
    sendToDiscord(message);
}

Server Status Updates

// Periodic status updates
public void updateServerStatus() {
    String status = String.format(
        "📊 Server Status: %d TPS | %d/%d players",
        getCurrentTPS(),
        Bukkit.getOnlinePlayers().size(),
        Bukkit.getMaxPlayers()
    );
    updateDiscordStatus(status);
}

Security Considerations

Bot Security

• Never share your bot token publicly
• Use environment variables for sensitive data
• Implement rate limiting for commands
• Regularly rotate bot tokens

Permission Management

# Secure permission setup
Permissions:
  AdminCommands:
    - restart
    - stop
    - whitelist
  ModCommands:
    - kick
    - ban
    - mute
  UserCommands:
    - status
    - list
    - help

Troubleshooting

Common Issues

Bot not responding: Check token and internet connection

Chat not syncing: Verify channel IDs and permissions

Roles not syncing: Check group mappings and Discord permissions

Debugging Tips

• Enable debug logging in your bot configuration
• Test with a simple command first
• Check Discord API status
• Verify bot has proper permissions

Performance Optimization

Bot Performance

• Use caching for frequently accessed data
• Implement message queuing for high traffic
• Monitor memory usage and CPU consumption
• Use efficient data structures

Server Impact

Minimize server impact with these strategies:

• Async operations for Discord communication
• Rate limiting for status updates
• Batch processing for multiple messages
• Caching player data

Conclusion

A Discord bot significantly enhances your Minecraft server's community engagement and management capabilities. Start with basic features and gradually add more advanced functionality as your community grows.

Remember to keep your bot updated and monitor its performance regularly for the best experience.
