Script Haxball Work May 2026

Haxball scripting refers to the use of JavaScript to automate, enhance, or moderate rooms in the browser-based physics game, . Most scripts utilize the Haxball Headless API

, allowing developers to run "headless" rooms (rooms without a visual client) that can handle complex logic like automated tournaments, player statistics, and custom game rules. Core Script Categories

Scripts are generally divided by their impact on the game environment: thenorthstar/HaxBall-Example-Scripts - GitHub

In HaxBall, scripting refers to the use of JavaScript to automate room management, create bots, or enhance the client-side experience. Since HaxBall is a physics-based browser game, its Headless API allows developers to host persistent rooms on servers without a graphical interface.

Part 7: The Future of Script Haxball

With Haxball's transition from Flash to HTML5, scripting has become more stable and powerful. Modern scripts can now: Script Haxball

• Stream data via Webhooks to Discord or Twitter for live match updates.
• Integrate with external databases (MySQL, MongoDB) for persistent player stats.
• Use AI to detect toxic behavior or balance teams automatically.
• Cross-room communication – one script managing multiple rooms simultaneously.

The community continues to innovate. New scripts are released weekly on forums like Haxball.cz, Haxforum, and GitHub.

3. Unique Game Modes

Scripts can break the soccer mold entirely.

• HAXBoom (Bomberman style): Players drop bombs when they die. The last player standing wins each round. The script disables the football and creates an arena-like stadium.
• Zombie Mode: One player starts as a "zombie" (slower speed, immune to goals). When the zombie touches another player, that player becomes a zombie. Survivors try to last a time limit.
• Catch The Flag (CTF): The football is replaced with a flag. Players must carry the flag to the enemy's spawn point.
• Volleyball / Tennis: The script modifies gravity and collision so the ball cannot touch the ground on your side.

Maintainability

• Modularize code: separate command parsing, moderation, match logic, and persistence into modules.
• Document commands, configuration options, and admin roles.
• Version control scripts and tag releases; provide changelogs so room admins know what changed.

Common use cases

1. Automated moderation

   • Auto-kick or auto-ban for offensive names, excessive spamming, or other rule violations.
   • Mute functionality and rate-limiting for chat.
   • Enforcing team balance (auto-team swap when teams are uneven).

2. Tournament and league management

   • Scheduling matches, automatically loading maps, and tracking match results.
   • Bracket progression, time limits, and match timers.
   • Generating and publishing standings and statistics.

3. Scoreboards, HUDs, and overlays

   • Displaying extended player stats: goals, assists, saves, time played, rating.
   • Live timers, countdowns, or custom scoreboard messages.

4. Custom game modes and rules

   • Implementing special mechanics (e.g., power-ups, timed abilities) by reacting to events and adjusting physics/score.
   • Creating mini-games or training drills inside rooms.

5. Replay, logging, and analytics

   • Recording match events for later review and analysis.
   • Exporting logs to external services (with consent) for stats aggregation.

6. Bots and AI

   • Player bots that can join as participants or provide practice opponents.
   • Spectator bots that provide commentary or automated refereeing.

4.1 Event-Driven Programming

HaxBall scripts operate on an event-driven model. The API provides callback functions that trigger when specific actions occur in the game.

• Player Management: onPlayerJoin, onPlayerLeave, onPlayerKicked.
• Game Flow: onGameStart, onGameStop, onTeamGoal, onTeamVictory.
• Physics & Input: onPlayerBallKick, onBallCollision, onPlayerChat.

Example: Welcome Message

room.onPlayerJoin = function(player) 
    room.sendAnnouncement("Welcome " + player.name + "!", player.id, 0x00FF00, "bold", 2);
;

Advanced Scripting Techniques

If you want to move beyond copy-pasting and actually write your own scripts, here are the advanced hooks you can use.
