Coal Ore

CoalMod

A data-driven mod for Hytale that adds coal ore to world generation using only JSON files - no Java code required!

Overview

CoalMod demonstrates how to add custom ores to Hytale using WorldGenOverlayLib. This mod is completely JSON-based and serves as a perfect example for resource pack creators who want to add ores to their worlds.

Features

No Java Code Required - Completely JSON-based

Coal Ore Generation - Adds coal ore across all zones (Zone0-Zone4)

Multiple Block Variants - Stone, Basalt, Sandstone, Shale, Volcanic variants

Automatic Integration - Uses WorldGenOverlayLib for seamless worldgen merging

Requirements

WorldGenOverlayLib is required! Make sure to install WorldGenOverlayLib before installing CoalMod.

WorldGenOverlayLib - Required dependency

Installation

Install WorldGenOverlayLib first

Place CoalMod JAR in your server's mods/ folder

Restart your server

The mod will automatically register coal ore generation when the server starts.

How It Works

CoalMod uses WorldGenOverlayLib's auto-discovery feature:

Overlay configuration is defined in Server/WorldGenOverlays/overlays.json

WorldGenOverlayLib automatically discovers and registers the overlay

Coal ore files are placed in the Ores/ZoneX/ structure

Placement references are automatically merged into Caves.json files

For Mod Developers

This mod serves as a complete example of the data-driven approach to adding ores. You can use it as a template for creating your own ore mods. All the JSON files are included in the mod JAR for reference.

Note: This mod requires WorldGenOverlayLib to function. Make sure both mods are installed.
