About this project

What does GTOUtils add?

GTOUtils

A small library mod shared by the GregTech Odyssey mods (Minecraft 1.20.1, Forge). It adds no blocks, items or gameplay of its own; install it only because another mod requires it.

What it provides

  • BlockOctree: a sparse octree over block coordinates with zero-allocation range queries.
  • BlockRange: sphere or box query ranges around a block.
  • BlockIndex / LevelBlockIndex: per-level indexes of block entities by position, so mods can find nearby machines, jars or pools without scanning every block in range.

Requires Forge for Minecraft 1.20.1 and Java 21.

Report issues on the GregTech Odyssey issue tracker and mention "GTOUtils" in the title.
