CobbleOreGenerator

CobbleOre Generator - Fabric 1.21.1

A Minecraft Fabric mod for version 1.21.1 that makes cobblestone generators generate ores! Based on the original mod by OffsetMods538.

Features

- Balanced by Default: When cobblestone is generated, there's a 25% chance it becomes an ore instead - Balanced by Default: JSON config file lets you control which blocks spawn and their weights - Balanced by Default: Works with any mod that adds ores - just add them to the config! - Balanced by Default: Comes with sensible default weights for all vanilla ores

How It Works

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.

Configuration

The config file is located at `.minecraft/config/cog.json`

Default Configuration

The mod comes with these default ore weights:

| Ore | Weight | Rarity | |-----|--------|--------| | Coal (both variants) | 30 each | Common | | Iron (both variants) | 25 each | Common | | Copper (both variants) | 20 each | Common | | Redstone (both variants) | 15 each | Uncommon | | Lapis (both variants) | 12 each | Uncommon | | Gold (both variants) | 10 each | Uncommon | | Diamond (both variants) | 3 each | Rare | | Emerald (both variants) | 2 each | Very Rare |

Config Format

The config uses a simple weight-based system. Higher weight = more common.

```json { "generatableBlocks": { "minecraft:cobblestone": 30, "minecraft:diamond_ore": 3, "minecraft:emerald_ore": 2 } } ```

Weight Examples: - 2 blocks with weight 1 each = 50/50 chance - Block A with weight 30, Block B with weight 1 = ~97% vs ~3%

Adding Modded Ores

Just add the block ID and weight to the config:

```json { "generatableBlocks": { "minecraft:diamond_ore": 3, "create:zinc_ore": 15, "thermal:silver_ore": 10, "mekanism:osmium_ore": 12 } } ```

Fun Configurations

Chaos Mode - Generate ANY block: ```json { "generatableBlocks": { "minecraft:diamond_block": 1, "minecraft:tnt": 1, "minecraft:cake": 10 } } ```

Easy Mode - More valuable ores: ```json { "generatableBlocks": { "minecraft:diamond_ore": 30, "minecraft:emerald_ore": 20, "minecraft:gold_ore": 50 } } ```

Compatibility

This mod should be compatible with most other mods. It only modifies the cobblestone generation behavior and uses mixins to hook into fluid interactions.

FAQ

Q: Does this work with modded ores? A: Yes! Just add them to the config file with their block ID and desired weight.

Q: Can I make it generate blocks other than ores? A: Absolutely! You can use any block ID in the config. Want cake generators? Go for it!

Q: The ores aren't generating! A: 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.

Q: Can I change the 25% chance? A: The percentage is hardcoded in the mod, but you can adjust the relative frequencies using weights in the config.

Q: Will this work on servers? A: Yes! Just install it on the server like any other Fabric mod.
