# Netherite Blocker Datapack<\/p>\n
**Minecraft Version:** 1.21.4
\n**Pack Format:** 61
\n**Purpose:** Disables Ancient Debris generation in the Nether<\/p>\n
## \ud83c\udfaf What This Datapack Does<\/p>\n
This datapack completely prevents Ancient Debris (Netherite ore) from generating in newly created Nether chunks. It works by overriding the vanilla placed features that control where and how Ancient Debris spawns.<\/p>\n
### \u26a0\ufe0f Important Notes<\/p>\n
– **New Chunks Only:** Only affects newly generated chunks in the Nether
\n– **Existing Chunks:** Any Ancient Debris already generated will remain
\n– **Complete Disabling:** No Ancient Debris will generate in future chunks<\/p>\n

## \ud83d\ude80 Installation Instructions<\/p>\n
### Method 1: New World (Recommended)<\/p>\n
1. Open Minecraft Java Edition 1.21.4
\n2. Create a new world
\n3. In the world creation menu, click “Data Packs”
\n4. Click “Available” and look for “Netherite Blocker”
\n5. Click the right arrow (>) to add it to your world
\n6. Click “Create New World”<\/p>\n
### Method 2: Existing World<\/p>\n
1. **Locate your world folder:**<\/p>\n
– **Windows:** `%APPDATA%.minecraftsaves[World Name]`
\n – **Mac:** `~\/Library\/Application Support\/minecraft\/saves\/[World Name]`
\n – **Linux:** `~\/.minecraft\/saves\/[World Name]`
\n2. **Copy the datapack:**<\/p>\n
– Copy the entire `netherite_blocker` folder
\n – Paste it into your world’s `datapacks` directory
\n3. **Enable the datapack:**<\/p>\n
– Start your world
\n – Run command: `\/datapack enable “file\/netherite_blocker”`
\n – Run: `\/reload`<\/p>\n
## \ud83d\udd27 Technical Details<\/p>\n
### How It Works<\/p>\n
The datapack overrides two vanilla placed features:<\/p>\n
1. **`minecraft:ore_ancient_debris_large`** – Large Ancient Debris clusters
\n2. **`minecraft:ore_ancient_debris_small`** – Small Ancient Debris clusters<\/p>\n
Each override sets the `minecraft:count` placement modifier to `0`, effectively preventing any instances of the feature from being placed in new chunks.<\/p>\n
### JSON Structure<\/p>\n
“`json
\n{
\n “feature”: “minecraft:ore_ancient_debris_large”,
\n “placement”: [
\n {
\n “type”: “minecraft:count”,
\n “count”: 0
\n },
\n \/\/ … other placement modifiers
\n ]
\n}
\n“`<\/p>\n
## \ud83d\udee0\ufe0f Troubleshooting<\/p>\n
### Common Issues<\/p>\n
**”Missing metadata” Error:**<\/p>\n
– Ensure `pack.mcmeta` exists at the root of your datapack
\n– Verify pack format is 61 for Minecraft 1.21.4<\/p>\n
**”No key feature” Error:**<\/p>\n
– Your JSON files are missing the required `feature` field
\n– Ensure placement modifiers are correctly ordered<\/p>\n
**Ancient Debris Still Spawning:**<\/p>\n
– Check that you’re exploring newly generated chunks
\n– Verify the datapack is enabled with `\/datapack list`
\n– Run `\/reload` to refresh datapack state<\/p>\n
## \ud83d\udcdd Uninstallation<\/p>\n
To remove the datapack:<\/p>\n
1. **Command Method:**<\/p>\n
“`
\n \/datapack disable “file\/netherite_blocker”
\n “`
\n2. **Manual Method:**<\/p>\n
– Delete the `netherite_blocker` folder from your world’s `datapacks` directory
\n – Run `\/reload`<\/p>\n
## \ud83d\udd17 Compatible Versions<\/p>\n

## \ud83d\udccb Commands Reference<\/p>\n
| Command | Description |
\n| ———————————————- | ——————————— |
\n| `\/datapack list` | List all loaded datapacks |
\n| `\/datapack enable “file\/netherite_blocker”` | Enable this datapack |
\n| `\/datapack disable “file\/netherite_blocker”` | Disable this datapack |

## \u26a0\ufe0f Server Considerations<\/p>\n
For server administrators:<\/p>\n
– **New worlds recommended** for complete effect
\n– **Backup existing worlds** before installation
\n– **Test in development environment** first
\n– **Monitor world generation logs** for verification<\/p>\n
## \ud83c\udfaf Expected Results<\/p>\n
After installation:<\/p>\n
– No new Ancient Debris will generate in explored Nether chunks
\n– Existing Ancient Debris in already-generated areas remains
\n– Players must find Ancient Debris through other means (trading, commands, etc.)
\n– This creates a resource scarcity challenge for server economies<\/p>\n
