No Elytra Boost

A lightweight server-side Fabric mod that prevents firework rockets from boosting elytra flight.

Features

• Prevents firework rocket boosting while gliding with an elytra
• Rockets are not consumed — the use action is simply cancelled
• Server-side only — no client mod required
• Zero performance impact — uses a simple event callback, no tick processing
• No race conditions — intercepts the use event before the game processes it, unlike datapack approaches

How It Works

The mod registers a UseItemCallback that cancels firework rocket usage when the player is fall-flying (elytra gliding). Normal firework launching (by hand, crossbow, or dispenser) is completely unaffected.

Installation

1. Drop the jar into your server mods folder
2. Restart the server

Requires Fabric Loader and Fabric API.
