room.onPlayerJoin = function(player) updateAdmins(); room.onPlayerLeave = function(player) updateAdmins();
Community developers expand upon this framework by integrating external databases (like SQLite or MongoDB) to save player profiles permanently, creating complex economy systems, or scripting entirely new game modes like Haxball RPGs and Racing. The Controversial Side: Cheating and Detection
The depth of scripting is perhaps best illustrated by advanced bots like the "Advanced Penalty Bot" by thenorthstar. This bot was "developed by reverse engineering method as the result of the developer's observations in public penalty rooms". It implements a complete penalty shootout logic with features like a turn-based system, a visual countdown timer and red arrow indicator for the active player, and logic to detect and punish players who waste time. This project demonstrates the incredible level of detail that can be achieved by dedicated scripters.
Haxball scripting typically refers to writing JavaScript code that interacts with Haxball’s Room API (used in the official Haxball Headless or embedded room instances). Scripts run either: Script Haxball
is a popular browser-based 2D soccer game. It relies heavily on physics, positioning, and fast reflexes. Over the years, a dedicated community of developers and players has created various types of Haxball scripts to modify the game, automate hosting, or gain a competitive edge.
This simple algorithm can be extended with whitelists, appeal mechanics, and graduated penalties.

// 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 Scripts run either: is a popular browser-based 2D
These scripts allow hosts to create automated, feature-rich public servers. Popular features include:
const playerStats = new Map();
room.onPlayerChat = function(player, message) if (message === '!tourney' && player.admin) tournamentMode = !tournamentMode; room.sendChat( Tournament mode: $tournamentMode ? 'ON' : 'OFF' );
⚠️ : This guide covers legitimate scripting for custom rooms. Using scripts to crash rooms, impersonate admins, steal passwords, or manipulate ball physics for cheating is a violation of Haxball’s rules and may result in bans.
