PermanentArrow
A lightweight Folia-compatible Minecraft plugin that makes arrows named "permanent" never disappear after being shot — they stay in the world until someone picks them up.
How It Works
- Name an arrow item
"permanent"in an anvil (or via/give). - Shoot it with a bow or crossbow.
- The arrow sticks wherever it lands and never despawns.
- Any player can pick it up and gets a reusable
"permanent"arrow back.
The arrow's display name is checked case-insensitively, so "Permanent", "PERMANENT", etc. all work.
Supported Arrow Types
- Regular arrows
- Tipped arrows (all potion variants — Poison, Healing, Harming, etc.)
- Spectral arrows
Requirements
- Server: Paper / Folia (or any Folia fork)
- API version: 26.1.2 (Minecraft 1.21.4)
- Java: 21+
The plugin supports Folia and uses no scheduler tasks — purely event-driven, safe on Folia's regionized threading model.
Installation
- Download the JAR from Releases.
- Drop it into your server's
plugins/folder. - Restart the server
Usage
In-game (anvil)
- Place an arrow in the first slot of an anvil.
- Rename it to
permanent(or any casing variation). - Take the renamed arrow and shoot it.
Building from Source
gradle buildThe JAR is output to build/libs/PermanentArrow-1.0-SNAPSHOT.jar.
Technical Details
The plugin registers two event handlers:
| Event | Purpose |
|---|---|
ProjectileLaunchEvent |
Detects when a player shoots an arrow whose item stack is named "permanent" and tags the arrow entity with a Persistent Data Container (PDC) key. |
ProjectileHitEvent |
For tagged arrows: makes them persistent across chunk loads, sets their lifetime to Integer.MAX_VALUE (never age-despawns), enables pickup for all players, and ensures the item stack retains the display name. |
No configuration file — the behaviour is intentionally zero-config. Name an arrow "permanent" and it works.
