🌈 Rainbow Armor v3.3.0

Thank you to MrSal for the persistence, in-game testing, and bug report that kept this issue alive, and to Cronu for looking into it as well.

What changed

🔧 Inventory interaction guard rewrite

The previous approach to preventing armor duplication and destruction was a blanket ban on all armor-related inventory interaction. This worked, but it was far too restrictive. Players couldn't even move a spare chestplate from their bag to a chest while wearing rainbow armor.

3.3.0 replaces this with a surgical approach. The guard now blocks only the exact interaction patterns that can actually cause a dupe or destroy a piece, and explicitly allows everything else.

✅ Now allowed while wearing rainbow armor

• Freely moving armor pieces between bag slots (click, drag, pick up, place down)
• Moving armor pieces into and out of external inventories (chests, barrels, shulkers, etc.)

❌ Still blocked — these are hard Minecraft limitations

Action	Why it's blocked
Click on an armor slot	The animator recreates the piece next tick → dupe
Drag onto an armor slot	Overwrites the rainbow piece → destruction
Shift-click any armor item	Minecraft always auto-routes to the nearest matching armor slot — the destination can't be intercepted
Right-click equip from hand	Same auto-equip behaviour
Hotbar number-key swap involving armor	Would move a piece into or out of the rainbow slot

---

🔔 Player feedback message

Blocked actions now show a configurable chat message so players understand why the interaction didn't work, rather than items silently disappearing.

New config.yml key (added automatically on first run):

armor-shift-click-blocked-message: '&(255,150,0)You can''t equip armor while wearing rainbow armor!'

---

🐛 Fixes

• Fixed ARMOR_RAW_SLOTS incorrectly including hotbar slots 36–39 (Paper 1.21 raw slot numbering), which was causing all hotbar interaction to be blocked
• Fixed creative mode consuming cancelled armor items due to client-side prediction — items are now explicitly restored to their slot server-side
• Fixed interaction guard relying solely on SlotType.ARMOR which is inconsistently reported across Paper versions — now also checks raw slot numbers 5–8 as a fallback

---

Full changelog

• ArmorListener: complete rewrite of inventoryClick, inventoryDrag, and onPlayerInteract guards
• ConfigKey: new ARMOR_SHIFT_CLICK_BLOCKED_MESSAGE entry
• config.yml: new armor-shift-click-blocked-message key

Rainbow Armor [1.21] v3.1.1

🛠️ Bug Fixes

• Fixed a critical issue where players could manually override rainbow armor by right-clicking with other armor.
• Now all armor interactions are blocked while rainbow armor is active.

Rainbow Armor [1.21] v3.0

Version 3.0 is here!

This is potentially the biggest update yet! Rainbow Armor now supports two completely separate modes of animation:

✨ Item-Bound Armor: Use /rainbowitem to give players real, tangible armor items that glow and animate on their own — even when stored!
⚔️ Player-Bound Armor: The classic toggle animation with /rainbow is still supported.
Fully Configurable Animation Context: Choose exactly where rainbow items animate!
Known Bug: Spam-clicking animated items may cause a duplication glitch. A fix is being explored.
New Config Options: Check out config.yml or the README on GitHub for details.

Enjoy the colors!
