# CobbleOre Generator – Fabric 1.21.1<\/p>\n
A Minecraft Fabric mod for version 1.21.1 that makes cobblestone generators generate ores! Based on the original mod by OffsetMods538.<\/p>\n
## Features<\/p>\n
– **25% Chance for Ores**: When cobblestone is generated, there’s a 25% chance it becomes an ore instead
\n– **Fully Configurable**: JSON config file lets you control which blocks spawn and their weights
\n– **Modded Support**: Works with any mod that adds ores – just add them to the config!
\n– **Balanced by Default**: Comes with sensible default weights for all vanilla ores<\/p>\n
## How It Works<\/p>\n
When lava and water interact to create cobblestone in a generator, this mod has a 25% chance to replace that cobblestone with a random ore based on weighted probabilities defined in your config file.<\/p>\n
## Configuration<\/p>\n
The config file is located at `.minecraft\/config\/cog.json`<\/p>\n
### Default Configuration<\/p>\n
The mod comes with these default ore weights:<\/p>\n
| Ore | Weight | Rarity |
\n|—–|——–|——–|
\n| Coal (both variants) | 30 each | Common |
\n| Iron (both variants) | 25 each | Common |
\n| Copper (both variants) | 20 each | Common |
\n| Redstone (both variants) | 15 each | Uncommon |
\n| Lapis (both variants) | 12 each | Uncommon |
\n| Gold (both variants) | 10 each | Uncommon |
\n| Diamond (both variants) | 3 each | Rare |
\n| Emerald (both variants) | 2 each | Very Rare |<\/p>\n
### Config Format<\/p>\n
The config uses a simple weight-based system. Higher weight = more common.<\/p>\n
“`json
\n{
\n “generatableBlocks”: {
\n “minecraft:cobblestone”: 30,
\n “minecraft:diamond_ore”: 3,
\n “minecraft:emerald_ore”: 2
\n }
\n}
\n“`<\/p>\n
**Weight Examples:**
\n– 2 blocks with weight 1 each = 50\/50 chance
\n– Block A with weight 30, Block B with weight 1 = ~97% vs ~3%<\/p>\n
### Adding Modded Ores<\/p>\n
Just add the block ID and weight to the config:<\/p>\n
“`json
\n{
\n “generatableBlocks”: {
\n “minecraft:diamond_ore”: 3,
\n “create:zinc_ore”: 15,
\n “thermal:silver_ore”: 10,
\n “mekanism:osmium_ore”: 12
\n }
\n}
\n“`<\/p>\n
### Fun Configurations<\/p>\n
**Chaos Mode** – Generate ANY block:
\n“`json
\n{
\n “generatableBlocks”: {
\n “minecraft:diamond_block”: 1,
\n “minecraft:tnt”: 1,
\n “minecraft:cake”: 10
\n }
\n}
\n“`<\/p>\n
**Easy Mode** – More valuable ores:
\n“`json
\n{
\n “generatableBlocks”: {
\n “minecraft:diamond_ore”: 30,
\n “minecraft:emerald_ore”: 20,
\n “minecraft:gold_ore”: 50
\n }
\n}
\n“`<\/p>\n

### For Developers:<\/p>\n
#### First Time Setup<\/p>\n
Before building, you need to set up the Gradle wrapper:<\/p>\n
**Option 1: Using the download script (easiest)**
\n“`bash
\n# Linux\/Mac
\nchmod +x download-wrapper.sh
\n.\/download-wrapper.sh<\/p>\n
# Windows
\ndownload-wrapper.bat
\n“`<\/p>\n
**Option 2: If you have Gradle installed**
\n“`bash
\ngradle wrapper
\n“`<\/p>\n
**Option 3: Manual download**
\nDownload `gradle-wrapper.jar` from:
\nhttps:\/\/raw.githubusercontent.com\/gradle\/gradle\/v8.8.0\/gradle\/wrapper\/gradle-wrapper.jar<\/p>\n
Place it in: `gradle\/wrapper\/gradle-wrapper.jar`<\/p>\n
#### Building the Mod<\/p>\n
Once the wrapper is set up:<\/p>\n
“`bash
\n# Linux\/Mac
\n.\/gradlew build<\/p>\n
# Windows
\ngradlew.bat build
\n“`<\/p>\n
The compiled `.jar` file will be located in `build\/libs\/`<\/p>\n
## Requirements<\/p>\n
– Minecraft 1.21.1
\n– Fabric Loader 0.16.0 or higher
\n– Fabric API 0.102.0+1.21.1 or higher
\n– Java 21 or higher<\/p>\n
## Compatibility<\/p>\n
This mod should be compatible with most other mods. It only modifies the cobblestone generation behavior and uses mixins to hook into fluid interactions.<\/p>\n
## FAQ<\/p>\n
**Q: Does this work with modded ores?**
\nA: Yes! Just add them to the config file with their block ID and desired weight.<\/p>\n
**Q: Can I make it generate blocks other than ores?**
\nA: Absolutely! You can use any block ID in the config. Want cake generators? Go for it!<\/p>\n
**Q: The ores aren’t generating!**
\nA: Make sure you have a proper cobblestone generator (lava + water creating cobblestone). Stone generators won’t work. Also remember it’s only a 25% chance.<\/p>\n
**Q: Can I change the 25% chance?**
\nA: The percentage is hardcoded in the mod, but you can adjust the relative frequencies using weights in the config.<\/p>\n
**Q: Will this work on servers?**
\nA: Yes! Just install it on the server like any other Fabric mod.<\/p>\n
