WorldGenOverlayLib

A library mod for Hytale that allows multiple mods to add custom ores to world generation without conflicts. No Java code required - add ores using only JSON files!

Quick Start

For Resource Pack Creators

Create Server/WorldGenOverlays/overlays.json in your resource pack:

{
  "Overlays": [
    {
      "Name": "My Ores Overlay",
      "Generator": "Default",
      "Ores": ["Coal", "Diamond"],
      "Zones": ["Zone0", "Zone1", "Zone2", "Zone3", "Zone4"]
    }
  ]
}

Create your ore files in Server/World/Default/Ores/ZoneX/:
- OreName.json - Defines ore structure
- OreNamePlacement.json - Defines placement settings
Add dependency to your manifest.json:

{
  "Dependencies": {
    "Hexvane:WorldGenOverlayLib": "1.0.0",
    "Hytale:WorldGen": "*"
  }
}

That's it! The library automatically discovers and registers your ores.
