ShulkerPlus

Open shulker boxes straight from your hand — sneak and right-click in the air — without ever placing them on the ground. Built from scratch for the CarraGeis pt.henrique suite (Paper/Purpur 1.21.x, Java 21) and dupe-safe by design.

Why another shulker plugin?

The public alternatives are either closed-source, unmaintained, or unaware of the other plugins on this server. This one is aware of them:

• CombatLOG — opening a shulker while tagged in combat is denied (configurable).
• BuildersDream — creative dream_items can never be placed inside a shulker, closing the hand-inventory laundering vector.

Features

• Open any shulker box directly from the main hand (sneak + right-click), no placement required.
• Configurable sneak requirement, open/close sounds, and combat behaviour.
• Clean, cancel-guarded GUI that behaves like a real shulker without the dupe risk.
• Lightweight: no required dependencies; the CombatLOG / BuildersDream hooks are optional and auto-detected.

Anti-dupe & stability

Opening shulkers from the hand is a classic dupe surface. ShulkerPlus is built to be safe:

• Slot-pinned: while the GUI is open, click, drop, hotbar-swap (F), number keys, drag and place are all cancelled, so the source item can never leave the slot mid-edit.
• No nesting: shulkers can never be placed inside other shulkers through the GUI.
• Stacks never open: Purpur allows oversized stacks; writing contents back onto a stack would multiply them, so stacked shulkers are refused.
• Write-back exactly once: on close, quit or death (including the death-drop case), tracked with a Persistent Data Container session tag. Orphaned tags left by a crash are cleaned up on join.

Configuration

require-sneak: true      # require sneaking to open
play-sounds: true        # open/close sounds
allow-in-combat: false   # allow opening while combat-tagged (CombatLOG)

Commands & permissions

• /shulkerplus reload — reload the configuration
• shulkerplus.use — use the plugin (default: everyone)
• shulkerplus.admin — administrative commands (default: op)
