Biome Builder Mod Banner

Biome Builder gives the player the ability to create Minecraft's biomes and structures, wherever they want.

Insipired by Terraria's mechanic of "placing down a number of specific blocks turns the area into a particular biome/structure", the mod adds two types of new blocks: Biome Anchors and Structure Anchors.

-Biome Anchors-

Biome Anchor Blocks

Step One

To build a biome using the Biome Anchor, simply interact with the biome anchor and select a biome of your choice.

Biome Category Selection Screen

Biome Selection Screen

Step Two

Then, fill in the requirements by placing required blocks within the biome anchor's range:

Biome Requirements Fulfilled

Step Three

Upon fulfilling the requirements, hit build to convert that chunk into the selected biome.

Converted Biome Confirmation

Be watchful of the requirements: Some biomes require a minimum/maximum elevation!

-Structure Anchors-

Structure Anchor Blocks

Structure Anchors function similarly to biome anchors, but they have an additional requirement:

Structure Anchors also require Adjacent Biomes

At least 3 directly adjacent chunks (North/East/South/West) must be a biome that the structure requires. If there are more than 2 biomes within a single chunk, it will only detect the biome of the center block (8, X, 8).

An Activated Structure Anchor causes the chunk and 24 blocks above & below it to count as a particular minecraft structure (Vertical Range is Configurable!). Example: Ocean Monuments- the area will spawn Guardians, Nether Fortresses spawn Blazes and Wither Skeletons, etc.
