There are several different units of measurement used in the protocol depending on what is being described. For example, it wouldn't make much sense to send the position of a block (which is a constant multiple of 32) in a floating point double.
A block represents 1 meter x 1 meter x 1 meter. There are 32 pixels per meter, and chunks are 16m x 128m x 16m.
| Data Types | Units | Represents | |
|---|---|---|---|
| Absolute | double | meters | Represents an object's location in the world. |
| Absolute Integer | int | pixels | Represents an object's location in the world. Functions the same as Absolute Double, but requires fewer bytes and is less precise. In C/C++/Java: absolute_int = (int)(absolute_double * 32.0);
|
| Block | byte, short, int | meters | Represents a block's location in the world. |
| Chunk | short, int | chunks | Represents the position of a chunk. |
