No Elytra Mod

No Elytra Mod is a lightweight server-side Fabric mod that gives you full control over elytra flight using a flexible rule-based system.

The mod does not remove or unequip elytra and does not affect Creative mode.
It simply enforces server rules and prevents flight when conditions are not met.

“You can wear it. You just can’t fly.”

✨ Features

Disable elytra flight based on rules:
- 📍 Dimensions (minecraft:overworld, minecraft:the_end, modded worlds)
- 🌧 Weather conditions (rain, thunder)
Modular rule-based architecture (easy to extend)
Elytra flight remains enabled:
- in Creative mode
- when no restriction rules apply
Fully server-side (no client installation required)
Command-based configuration
Automatic config saving
No datapacks required

🧠 How It Works

The mod uses a rule system:

each rule checks a specific condition (dimension, weather, etc.)
if any rule blocks flight, elytra gliding is disabled
players receive a contextual message explaining why

No teleportation, no damage, no hacks — just clean control.

🔌 Extending the Mod

The mod uses Java's ServiceLoader to automatically load rules.

This makes it easy to add new restriction types such as:

time of day
biomes
player-specific rules
