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.
