Key Items

Key Items adds a dedicated 27-slot Key Items pouch that allows players to store and use utility items, consumables, and accessories via hotkeys without taking up space in the vanilla hotbar or main inventory.

Features

• 27-Slot Persistent Pouch: A separate inventory accessed via keybind or a key button inside the player inventory. Items in the pouch are preserved through death.
• Quick-Use Hotkeys: The first 9 slots can be activated directly via hotkeys:
• Instant Use: Throw Ender Pearls, splash potions, or place blocks directly where you're aiming.
• Continuous Actions: Hold to block with Shields, charge Bows, or eat Food.
• Crossbows: Hold to load an arrow; tap while loaded to fire immediately.
• Curios Compatibility: Accessories placed in the pouch provide their passive effects and attribute modifiers (e.g. max health, speed, magnets). All Curios items are not designated as key items by default.
• Universal Totem of Undying: Any vanilla or modded totem in the pouch will trigger upon fatal damage.
• Ammo Supply: Bows and crossbows automatically draw arrows or fireworks stored in the pouch.
• Sidebar HUD: A compact, semi-transparent on-screen overlay displays the 9 active slots, durability bars, cooldown sweeps, and stack counts.
• Custom Tooltips: Items display a yellow ★ Key Item tag, or a purple ✦ Eternal Key Item tag if configured for infinite use.

Configuration

The mod generates a configuration file at config/keyitems-common.toml. It allows you to:

• Enable or disable global item acceptance (allow_all_by_default).
• Whitelist specific item IDs allowed into the pouch (allowed_items).Designate items that never lose durability or stack count (infinite_items).

All keybindings (default K to open, Numpad 1–9 to activate slots) can be customized in the vanilla Controls menu.

Datapack & KubeJS Support

Modpack creators can configure Key Items using item tags:

• #keyitems:allowed — Items allowed into the pouch.
• #keyitems:infinite — Items that bypass durability loss and consumption.

KubeJS Example (kubejs/server_scripts/keyitems.js):

ServerEvents.tags('item', event => { 

event.add('keyitems:allowed', [ 'minecraft:ender_pearl', 'minecraft:shield', '#c:tools', '#curios:curio' ])

event.add('keyitems:infinite', [ 'minecraft:shield', 'minecraft:arrow' ])

})

Datapack Example (data/keyitems/tags/item/allowed.json):

{

"replace": false,

"values": [ "minecraft:ender_pearl", "minecraft:shield", "#curios:curio" ]

}
