Shared Structures

Shared Structures enables custom prefab structure generation in existing biomes using vanilla-style placement patterns. Created by joshieman, this mod lets modders add their structures to world generation without complex code.

What Does This Mod Do?

• Loads structure entries from your asset packs
• Places prefabs during world generation using pattern rules
• Supports grid, noise, height, parent, and mask-based placement
• Handles entities and block spawners in prefabs

For Developers

Adding Structures

Create JSON config files in your pack at:

Server/WorldGen/SharedStructures/Prefabs/*.json

Each file contains an array of structure entries.

Example Configuration

[
  {
    "Id": "castlearena",
    "Prefab": ["YourPack.CastleArena"],
    "Weight": [1.0],
    "BiomeMask": ["*Plains*"],
    "ZoneMask": ["Zone1_Tier1"],
    "Pattern": { "File": "World.Default.Zones.Pattern_Monuments" }
  }
]

Configuration Fields

• Id: Unique name for the entry
• Prefab: Prefab asset ID(s)
• Weight: Weights matching the Prefab list
• BiomeMask: Wildcard match against biome ID
• ZoneMask: Wildcard match against zone ID
• Pattern: File reference or inline pattern object

Notes

• Patterns resolve relative to the worldgen data folder
• A file reference A.B.C loads A/B/C.json
• Store prefabs under Server/Prefabs/ in your pack

Key Features

Vanilla-Style Patterns

Use the same placement patterns as vanilla structures.

Flexible Masking
