OneWay Elytra

A Minecraft plugin for Paper/Spigot 1.21.1 that implements a special Elytra system with radius-based restrictions.

What does this plugin do?

This plugin creates a "OneWay Elytra" system where certain Elytras can only be used within a configurable radius around a spawn point. Normal Elytras work as usual and are not affected.

Features

• Radius-based Elytra usage: OneWay Elytras can only be worn within a defined radius around the spawn point
• Automatic Elytra management:
  • Players automatically receive a OneWay Elytra when entering the radius
  • The Elytra is automatically removed when players leave the radius (only when not gliding)
  • Action bar warning when chestplate slot is occupied: "Remove your chestplate first to receive the OneWay Elytra!"
• Abuse prevention:
  • New gliding cannot be started outside the radius
  • Players already flying can continue their flight until landing
• Landing detection: When a player lands outside the radius, the Elytra is automatically removed
• Flexible removal modes:
  • MOVE_TO_INVENTORY: Elytra is moved to inventory (or dropped if full)
  • DROP: Elytra is immediately deleted (cannot be picked up)
• Multilingual support:
  • German (de) and English (en) language files included
  • All messages can be customized in lang/de.yml or lang/en.yml
  • Config option lang: de or lang: en to switch languages

Installation

1. Download the OneWayElytra-1.0.0.jar file
2. Place it in your server's plugins folder
3. Restart your server
4. Configure the spawn point and radius (see below)

Configuration

The configuration file is located at plugins/OneWayElytra/config.yml:

# OneWay Elytra Plugin configuration
# Language: de = German, en = English (message files in plugin folder: lang/de.yml, lang/en.yml)
lang: en

# Spawn point (world + coordinates)
spawn:
  world: "world"
  x: 0.0
  y: 64.0
  z: 0.0

# Radius in blocks
radius: 100

# Remove mode when leaving zone: MOVE_TO_INVENTORY or DROP
removeMode: "MOVE_TO_INVENTORY"

# Debug mode (extra console output)
debug: false

Language Files

All player-facing messages are stored in language files:

• plugins/OneWayElytra/lang/de.yml - German messages (default)
• plugins/OneWayElytra/lang/en.yml - English messages

These files are created automatically on first start and can be edited to customize messages. Use & for color codes (e.g., &c for red, &a for green).

Commands

/oe setspawn

Sets the spawn point to your current position.

/oe setradius <blocks>

Sets the radius in blocks (e.g., /oe setradius 50).

/oe setremovemode <MOVE_TO_INVENTORY|DROP>

Changes the removal mode:

• MOVE_TO_INVENTORY: Elytra is moved to inventory
• DROP: Elytra is deleted

/oe info

Shows the current configuration (spawn point, radius, removal mode).

/oe reload

Reloads the configuration file and language files.

/oe give <player> [amount]

Gives a player one or multiple OneWay Elytras.

/oe tag

Marks the Elytra in your hand as a OneWay Elytra.

/oe untag

Removes the mark from the Elytra in your hand.

/oe check

Checks if the Elytra in your hand is a OneWay Elytra.

Aliases: /onewayelytra, /oneway

Permissions

• onewayelytra.admin - Allows all admin commands (default: OP)
• onewayelytra.bypass - Ignores all OneWay Elytra rules (default: OP)

How it works

1. Elytra marking: OneWay Elytras are marked via PersistentDataContainer (PDC) with a special tag
2. Automatic distribution: When a player enters the defined radius without a OneWay Elytra, they automatically receive one
3. Glide protection: When starting a glide, the plugin checks if the player is within the radius. Outside the radius, the start is blocked
4. Landing detection: A task checks every 2 ticks if players have landed and removes the Elytra if they're outside the radius

Technical Details

• API Version: 1.21.1
• Dependencies: None (Paper API only)
• Java Version: 21
• Marking: PersistentDataContainer with NamespacedKey onewayelytra:oneway

Troubleshooting

Problem: Elytra is not automatically given/removed

• Check if the spawn point is correctly set (/oe info)
• Check if you're within the correct radius
• Enable debug mode in the config (debug: true) and check the console

Problem: Special characters are displayed incorrectly

• Make sure the config file is saved as UTF-8
• The build file is already configured for UTF-8
