OpenShulker

OpenShulker – Open Shulker Boxes in Hand, Right‑Click Air

OpenShulker is an ultra‑lightweight Paper / Folia plugin that does one simple thing: lets players open a shulker box GUI by right‑clicking air while holding it – no need to place the box on the ground.

Key Features

• Instant Access – Hold any shulker box and right‑click in the air to open the GUI instantly.
• Ultra‑Lightweight – Zero configuration, zero dependencies, minimal performance footprint.
• Drop‑and‑Go – Just place it in the plugins folder – no setup required.
• Folia‑Ready – Optimised for Folia's threading model, compatible with Paper and its forks (e.g. Purpur).
• Built‑in Protection – Includes anti‑exploit measures to prevent item duplication via GUI interactions.
• Open Source – Licensed under the MIT License – free to use, modify, and distribute.

Requirements

• Server Version: Paper 26.1.2+ or Folia 26.1.2+
• Not Compatible With: Spigot / CraftBukkit

How to Use

1. Place the .jar file into your server's plugins folder.
2. Restart the server (a restart is recommended over /reload).
3. Players hold any shulker box (including dyed variants) and right‑click on air – the GUI will open immediately.

   Note: Right‑clicking on a block will still place the shulker box normally, so building is not affected.

Notes

• This plugin only adds the open‑in‑hand functionality; it does not alter placement, breaking, or redstone behaviour.
• Completely configuration‑free – ready to use out of the box.
