Game Events Reference

All script event handlers use camelCase — but the engine matches them case-insensitively, so both onDeath and ondeath work. Use camelCase for readability.

Player Script Events

Player events are defined in player script classes (e.g. player_events.js). The player instance is always this, not a player parameter. Think of each player as running the script themselves.

function onLogin() { }
