Units of Measurement
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 256m x 16m.
|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.
|Block||byte, short, int||meters||Represents a block's location in the world.|
|Chunk||short, int||chunks||Represents the position of a chunk.|
