Dimension and Elytra Control

Dimension and Elytra Control is a lightweight server-side mod that lets server administrators control access to the End, access to the Nether, and Minecraft's standard elytra flight through game rules.

The mod is installed only on the dedicated server. Players do not need to install it.

All restrictions are disabled by default, so installing the mod does not change normal gameplay until an administrator enables the required game rules.

Features

• Block travel to the End.
• Block travel to the Nether.
• Block Minecraft's standard fall-flying mechanics.
• Control each restriction independently.
• Apply changes immediately without restarting the server.
• Store all settings as normal per-world game rules.
• Preserve elytra items, equipment, durability, and status effects.
• Support vanilla and compatible modded elytras.
• Require no client-side installation.

Game rules

Game rule	Default	Description
disableEnd	false	Blocks travel to the End
disableNether	false	Blocks travel to the Nether
disableElytraFlight	false	Blocks standard Minecraft fall flying

Commands

End access

/gamerule disableEnd true
/gamerule disableEnd false

Nether access

/gamerule disableNether true
/gamerule disableNether false

Elytra flight

/gamerule disableElytraFlight true
/gamerule disableElytraFlight false

Changes take effect immediately and are saved with the world.

Elytra compatibility

The mod blocks Minecraft's standard fall-flying state instead of maintaining a hardcoded list of item IDs.

This allows it to cover:

• Vanilla elytras
• Compatible modded elytras
• Temporary flight effects that use standard fall flying
• Other items or effects based on Minecraft's elytra-flight mechanics

The mod does not remove, damage, or unequip elytras, and it does not remove related status effects.

It is not intended to affect:

• Creative flight
• Jetpacks
• Levitation
• Create: Aeronautics
• Vehicles or aircraft that do not use standard fall flying
• Other flight systems independent of elytra mechanics

Installation

1. Install NeoForge for Minecraft 1.21.1 on the server.
2. Download the mod JAR.
3. Place the JAR in the server's mods directory.
4. Restart the server.
5. Enable the desired restrictions using the game-rule commands.

Clients do not need to install the mod.

Nether configuration

It is recommended to keep the following setting in server.properties:

allow-nether=true

Nether access can then be controlled through the disableNether game rule without restarting the server.

When allow-nether=false, the vanilla server disables the Nether independently, and this mod cannot restore access using a game rule alone.

Requirements

• Minecraft 1.21.1
• NeoForge 21.1.x
• Java 21
