Checkers World
by KyivSec
Checkers World replaces standard terrain with a generated world of alternating two-block cube segments when a player picks the Checkers world type.
What it does
Creating a new world and selecting the Checkers world type produces a clean, decoration-free checkerboard built from alternating cube segments along the X, Y and Z axes. Rather than natural landscape, the world generator arranges two selected block types into a repeating grid, a layout that works for test areas, building canvases, redstone setups and controlled challenge maps.
The world creation screen exposes the options that shape the pattern: the first block, the second block, the segment size, the depth level, the starting Y height and whether a bedrock floor is placed at the bottom. Depth is measured downward from the chosen starting Y. Vanilla structures, landmarks and biome decoration are not generated in Checkers worlds.
The mod runs on the server alone under NeoForge 1.21.1, so players join without installing anything. The latest file, 1.0.0 for 1.21.1, was published on 2026-04-21, and the code is open source under the MIT License.
Key features
Checkerboard terrain
Generates a decoration-free world of alternating cube segments in a regular checkered layout.
Configurable blocks
The first and second block can be set separately, so the palette of each world is chosen at creation.
Segment and depth settings
Segment size, depth level and starting Y control how large each cube is and how far the pattern extends downward.
Optional bedrock floor
A toggle places a bedrock layer at the bottom of the generated depth, or leaves the bottom open.
