Module position

Representations of positions of various things in Minecraft.

The most common ones are Vec3 and BlockPos, which are usually used for entity positions and block positions, respectively.

Structs

BlockPos

The coordinates of a block in the world. For entities (if the coordinate have decimals), use Vec3 instead.

ChunkBlockPos

The coordinates of a block inside a chunk.

ChunkPos

Chunk coordinates are used to represent where a chunk is in the world. You can convert the x and z to block coordinates by multiplying them by 16.

ChunkSectionBlockPos

The coordinates of a block inside a chunk section. Each coordinate must be in the range [0, 15].

ChunkSectionPos

The coordinates of a chunk section in the world.

GlobalPos

A block pos with an attached world

Vec3

Used to represent an exact position in the world where an entity could be.

Vec3i

Similar to BlockPos but it’s serialized as 3 varints instead of one 64-bit integer, so it can represent a bigger range of numbers.
