🏰 Castle Shift - Castles in Your World
Discover stone brick castles naturally generated across the landscape!
Castle Shift is a structure mod that adds multi-story castles to Minecraft's world generation. Each castle features randomized structural variations, so no two castles are exactly alike.
✨ Features
🏗️ Multi-Story Castles
- 4-Floor Structures: Grand castles with walls, towers, and corridors
- Natural Placement: Castles generate organically in a wide variety of biomes
🎨 Randomized Materials
Each castle's roofs, walls, and stairs are built from materials randomly selected per castle, so no two castles look the same!
- Roofs: Spruce, Dark Oak, Deepslate Bricks, Dark Prismarine, Red Nether Bricks, Crimson
- Walls: Stone Bricks, Deepslate Bricks, Polished Blackstone Bricks, Sandstone, End Stone Bricks
- Stairs: Bricks, Stone Bricks, Polished Granite, Deepslate Bricks, Polished Blackstone, Polished Blackstone Bricks, Red Nether Bricks
🧱 Structural Variations & Weathering
- Multiple Templates: Each floor section (walls, corners, centers, towers) has multiple structure templates chosen at random
- Wall Weathering: Stone brick and polished blackstone brick walls may randomly degrade into cobblestone, andesite, or cracked variants for a lived-in look
📦 Datapack-Friendly
- Structure placement can be customized via datapacks
- Adjust spacing, separation, and biome filters to your liking
