Mansioneer

Have you ever wondered why Woodland Mansions were only built in Dark Oak Forests? Have you ever wanted a vanilla-flavored incentive to go exploring? With Mansioneer, Woodland Mansions will generate in many biomes scattered around your world! Each mansion seamlessly blends into its environment, making exploration more rewarding and interesting.

Where do Woodland Mansions generate?

Mansioneer currently expands Woodland Mansions to generate in swamp, savanna, taiga, jungle, desert, forest, birch forest, icy, snowy, plains, and mountain slope biomes, along with variants thereof. It also allows them to generate in Cherry Grove and Pale Garden biomes. Each biome type will have its own block palette and theme!

What do Woodland Mansions look like?

Take a look at the media tab! It features a selection of the many variants that Mansioneer adds.

Can I move into a Woodland Mansion?

Yes, as long as you can evict the Pillagers! Some variants of Woodland Mansions may require some renovations, while others - like the vanilla one - only need some more torches to be added. Alternatively, you can tear them down for a plentiful source of materials and build your own mansion!

How does this work?

Mansioneer modifies the default logic for Woodland Mansions. When Minecraft places one, Mansioneer will swap out the block palette using a datapack-defined "block transformer". This means that it should be instantly compatible with mods or datapacks that change the look of Woodland Mansions.

Why are the chests still giving Dark Oak Saplings?

Mansioneer doesn't change chest loot - the "block transformer" system isn't currently fine-grained enough to change the loot tables of chests. Instead, it directly swaps out one block for another.

I'm making a modpack; how does this work with other mods?

Mansioneer should play nicely with other mods that edit the vanilla Woodland Mansion by default! If you want to add specific variants for modded biomes - or variants that use modded materials - take a look at the data files in /data/___/mansioneer. You can create new block transformer palettes, new biome-to-block-transformer mappings, or both!
