To host an automated room, you need to use the Haxball Headless API. Below is a foundational JavaScript blueprint that initializes a public room, configures standard settings, and implements a basic automated welcome message. javascript
Every script starts by initializing the room with specific settings. Use the function to define these parameters: : The public name of your room. playerName : The name the host bot will use. maxPlayers : Limit the number of players (e.g., 12). to show it in the room list. 3.

. By leveraging the HaxBall Headless Host API , developers and server hosts write JavaScript code to automate admin duties, track statistics, handle complex rules, and introduce entirely new gameplay mechanics like superpowers and ranking systems.
const commands = '!ping': (player) => room.sendChat(`Pong! $player.name`, player.id); , '!players': () => const players = room.getPlayerList(); const names = players.map(p => p.name).join(', '); room.sendChat(`Online players ($players.length): $names`); , '!clear': (player, args) => if (player.admin) for(let i = 0; i < 10; i++) room.sendChat(''); room.sendChat(`Chat cleared by $player.name`);

Only join rooms from trusted hosts. Never download external "Haxball clients" that claim to give you advantages. And if you host, keep your scripts open-source to build trust. Adding custom chat macros, changing field colors, or
A Haxball script is a piece of JavaScript code used to modify the game environment or automate room management. Because the game runs entirely in the browser, it interacts seamlessly with web scripts. These scripts generally fall into two categories:

Since scripts are written in JavaScript, you can open them in any text editor. Avoid running compiled or obfuscated code that you cannot read.
Critical for public rooms, these scripts can auto-ban toxic players based on word filters or prevent spamming. 2. How to Use Haxball Scripts If you share with third parties, their policies apply
is a deceptively simple, highly competitive top-down soccer simulation game. While the core gameplay is straightforward, the community has developed a thriving ecosystem of scripts to transform the game experience.
// Set room settings room.setCustomStadium("Stadium name"); room.setScoreLimit(5); room.setTimeLimit(10); room.setTeamsLock(true); room.setTeamColors(1, 0xFF0000, 0x0000FF); // Team 1 red, Team 2 blue
The script automatically balances teams based on who is waiting in the lobby and starts the match.
Checks the IP addresses of incoming players to restrict room entry to specific regions, ensuring low ping and a lag-free experience. 5. Security and Fair Play (Anti-Cheat Scripts)
