LockIT

🔑 Master Keys Combine keys in an anvil to create one key that opens several locks.

• Put a key in the first slot and the key to merge in the second slot. The result holds the codes of both keys, and the second key is consumed.
• Repeat to add as many codes as you like.
• Merged keys are named Master Key and get their own model, so they look different from regular keys.
• Type a name in the anvil to rename the key while merging.
• Every code a key holds is listed in its tooltip.
• Copy a master key onto a blank key to duplicate it with all its codes.

🎨 Resource Pack (1.21 – 26.3)

• New textures for all 6 locks, keys, lockpicks, and both menus.
• Sent automatically when players join, so there's nothing for them to install.
• Fully optional: set resource-pack.enabled: false in config.yml to play without textures.
• Players who don't load the pack still get the normal menus.

🔒 New Lock Menu

• The lock menu is now a hopper menu with the lock in the middle slot.
• The other slots stay empty and can't hold items.

📌 Named Pins

• The pins in the lockpicking minigame are now called Pin (editable with lp_pin_name in messages.yml).

⚙️ New Config Options

config.yml

• master-key.enabled: turn anvil merging on or off (default true)
• master-key.xp-cost: XP levels per merge (default 5, minimum 1; costs above 40 are allowed)
• master-key.max-codes: max codes per key (0 = no limit)
• resource-pack: enabled, url, sha1, id, prompt, required

items.yml

• master_key: name and custom_model_data (102) for master keys

🛠️ Fixes & Tweaks

• Item names no longer show raw color codes (like &fKey), including when renaming in an anvil.
• A master key can't program a lock, since a lock holds one code. You now get a clear message instead.
• The anvil only accepts one key in the first slot, so stacked keys are never lost.
• Merging keys that add no new code shows no result, so no XP is wasted.

📦 Updating

• Just replace the jar. New config options are added automatically, and your settings are kept.
• Existing keys and locks keep working, with nothing to migrate.
• If you were sending a resource pack through server.properties, remove it there so players don't get it twice.
