Radial Resource Gating

Ore generation is checked per feature. When a feature starts generating, the mod reads its origin: if the origin lies inside the allowed square, the whole feature generates normally; if it lies outside, the whole feature is cancelled. Features are never trimmed at the border, which keeps the check fast and simple. Only newly generated chunks are affected, and existing chunks are not modified.

The gate is set up through a common TOML config that NeoForge creates on the first run. Each of the Overworld, Nether and End has its own section and can be enabled or disabled separately. The centerMode setting picks the midpoint of the allowed area: the default, set world spawn, anchors it to the Overworld spawn saved in the world, while set fixed anchors it to the centerX and centerZ numbers from the config. The range option sets how far the square extends from the center, so a range of 256 allows ores up to 256 blocks from the center on each side.

The mod is server-side only, so only the server needs it and players join without installing anything. It requires NeoForge for Minecraft 1.21.1, and the latest file is 0.2.0 for 1.21.1, published on 2026-07-11.
