Introduce a Modular, Data-Driven System for Tools, Weapons, and Armor

We propose a unified, component-based system to replace static tool classes. This grants data pack creators the power to define entirely new gear without needing new item IDs.

Core Design: Three Base Items

• minecraft:tool

• minecraft:weapon

• minecraft:armor

How It Works:

1. Creators add JSON files to data/<namespace>/tool/, /weapon/, or /armor/.

2. Each file defines a unique item's full properties.

3. The game references it via a Synthetic ID (e.g., mypack:copper_pickaxe), usable anywhere a real ID is needed (commands, recipes).

Definable Properties (Examples):

• Stats: Damage, Speed, Durability, Mining Level.

• Behaviors: Mineable blocks (#minecraft:mineable/pickaxe), Blockable, Throwable, Chargeable.

• Cosmetics & Effects: Custom model/texture, "Egg-like" hatch behavior.

Key Advantages:

• Limitless Creation: Enables "Obsidian Swords" or "Gem Drills" without consuming item IDs.

• Absolute World Safety: Items are based on eternal IDs like minecraft:tool. Removing a data pack turns them harmless, never causing corruption.

• Future-Proof Framework: Establishes a standardized, powerful system for all creators.

The Big Picture:
This system transforms Minecraft from manually adding content to providing a creation engine. Combined with generic "Item Interface" materials, it forms the ultimate toolkit for the community, with minimal long-term cost for Mojang.
