# 📦 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
```
