A Haxball script is a piece of JavaScript code designed to automate or enhance the gameplay experience in the popular 2D browser-based soccer game, Haxball. These scripts generally fall into two categories: Headless Bot Scripts, used by room hosts to automate management, and User Scripts, which individual players use to customize their own interface or controls. 1. Types of Haxball Scripts
Scripts can range from simple chat commands to complex AI-driven bots that manage entire leagues.
Room Management Bots: These scripts run on a "Headless" host and handle tasks like automatically starting matches, switching teams, and recording goals.
Gameplay Enhancements: Some user scripts add visual indicators, such as ball trajectory predictors or movement-based avatar animations.
Macros: Tools like AutoHotkey or specialized JS macros allow for "fast kick" or "rapid fire" actions by sending multiple inputs in rapid succession.
Security & Moderation: Critical for public rooms, these scripts can auto-ban toxic players based on word filters or prevent spamming. 2. How to Use Haxball Scripts
Depending on your goal—hosting a room or improving your play—the installation method differs. For Room Hosts (Headless API)
To host an automated room, you typically use the Haxball Headless Page.
Open the Headless Page: Navigate to the official Haxball headless URL. Open DevTools: Press F12 and click on the Console tab.
Inject the Script: Copy and paste your JavaScript code (like those found on GitHub) into the console and press Enter. Script Haxball
Solve Captcha: Complete the security check to launch the room link. For Players (User Scripts)
Individual enhancements are usually managed through browser extensions like Tampermonkey or Greasy Fork. sharing EFC room-bot script · Issue #611 - GitHub
When scripting for , the goal is usually to automate room management or add gameplay mechanics that aren't in the base game. Depending on whether you want to build a Headless Bot (server-side) or a Client-Side Macro , here are a few feature ideas: 1. Advanced Stat Tracking (Server-Side) Building on existing stats scripts , you could implement a "Heatmap & Possession" Territory Possession
: Track how much time the ball spends in each half or "zone". Live Expected Goals (xG)
: Calculate the probability of a goal based on the distance to the goal and the number of defenders between the kicker and the net. Persistent Leaderboards SQLite database
to save player ELO, win streaks, and career goals across sessions. 2. Gameplay Mechanics (Server-Side) You can use the Headless API to change how the game feels: : Trigger "abilities" like a when a player sends a specific chat command or hits a key. Nearest Player Logic
: Automatically assign "Captain" status or "Defender" roles to the player closest to the ball Automatic AFK Kick
: If a player's position hasn't changed for 30 seconds, automatically move them to spectator or kick them. 3. Quality of Life (Client-Side) If you are using AutoHotkey
or browser overrides, you can focus on mechanical consistency: Double Kick Macro A Haxball script is a piece of JavaScript
: A script that sends two rapid "kick" inputs to give the ball extra weight or a specific angle.
: A macro to help "stick" to the ball when it is pinned against the wall by rapidly cycling the kick button. Joining History
: A client-side snippet to see a player's previous nicknames or join times to identify returning trolls. 4. Moderation Tools (Discord Integration) Remote Management
: Link your room to a Discord bot to open/close rooms, ban players, or change maps Match Recording : A script that triggers a command to save the last game as a replay file. How to implement these: Most of these features are written in JavaScript and pasted into the HaxBall Headless Host console. You can find a library of starter scripts on to build from. basic code template

A Haxball script is a piece of code, usually written in JavaScript, that automates or enhances the gameplay experience within the physics-based online soccer game, Haxball. These scripts range from simple client-side macros to complex "Headless" bot scripts that manage entire game rooms automatically. Types of Haxball Scripts
Scripts in Haxball generally fall into three main categories based on their function and where they run:
Headless Bot Scripts: These are the most common and powerful scripts. They use the Haxball Headless API to host rooms without a graphical interface. They can automate team balancing, score tracking, and admin tasks.
Userscripts (Client-side): These run in the player's browser using extensions like Tampermonkey. Popular examples on Greasy Fork include scripts for changing avatars, adding chat bubbles, or enhancing the room search. // Monitor performance let lastTime = Date
Macros and Input Scripts: These tools, often found on platforms like BotMek, automate keyboard inputs to perform repetitive actions like "fast kicks" or "tank mode" movement. Core Features of Modern Bot Scripts
High-quality scripts, such as those provided by developers like Wazarr94 or thenorthstar, typically include the following features: sharing EFC room-bot script · Issue #611 - GitHub
// Debug logger function debugLog(message) console.log(`[DEBUG $new Date().toLocaleTimeString()] $message`); room.sendChat(`🔧 $message`);// Error handling wrapper function safeExecute(fn, fallback) try return fn(); catch (error) console.error('Script error:', error); return fallback;
// Monitor performance let lastTime = Date.now(); setInterval(() => const now = Date.now(); const fps = 1000 / (now - lastTime); debugLog(Performance: $Math.round(fps) FPS); lastTime = now; , 5000);
The industry standard. HBHM is not a script but a framework. It allows you to load multiple scripts, manage room rotations, and auto-restart crashed rooms. Most large public rooms (e.g., "Noob Room," "Professional Zone") run on HBHM.
A script can run a "King of the Hill" or "Losers Out" tournament without any human admin.

It is important to distinguish between Room Scripts and Client-side Hacks.
