📦 Datapacks & Dev-World Overview

🎒 1. datapacks/ — Minecraft’s Built-In Modding System

Datapacks are Minecraft’s official way to add custom game logic without installing mods.
They allow you to create:

• 🍲 Recipes
• 🎁 Loot tables
• 🗺 Structures
• ⚙️ Commands/functions
• 🌌 Dimensions
• 🏆 Advancements
• 🌱 Worldgen features
• 👾 Mob behavior (via loot/function triggers)

Datapacks live inside:

world/datapacks/

(or inside any other world folder you choose).

📁 Example Structure

world/
  datapacks/
    my_custom_pack/
      pack.mcmeta
      data/
        minecraft/
        mypack/

⚡ How Datapacks Work

• When the server starts, Minecraft automatically loads all datapacks in that folder.
• You can reload them live with:

/reload

🧠 Why Track Datapacks in Git?

Because datapacks are basically tiny mods made from text files, Git gives you:

• Full version control
• Rollbacks for bad experiments
• A safe way to iterate
• Easy syncing between machines
• A complete history of every change

Note: Minecraft 1.1 did not support datapacks yet — but this structure is useful for future worlds or modern servers.

🌍 2. dev-world/ — A Safe Testing Sandbox

dev-world/ is not a built-in Minecraft feature.
It’s a folder you create to safely test changes without risking the real world.

🎯 Purpose

Use this sandbox world to test:

• Dangerous commands
• Datapack functionality
• Worldgen changes
• NBT edits
• Anything experimental

📁 Example Structure

dev-world/
  level.dat
  region/
  playerdata/

This mirrors your real world/ folder.

💡 Why a Dev World?

• Reset it instantly
• Duplicate it whenever needed
• Safely break anything
• Prototype new features
• Avoid griefing or corrupting the main world

🔧 How to Use dev-world/

In your server.properties, set:

level-name=dev-world

Start the server → it loads the dev world.

When you're finished testing, switch back:

level-name=world
