| − | 64-bit value split in to three parts
| |
| − | | |
| − | * x: 26 MSBs
| |
| − | * z: 26 {{change|LSBs|middle bits}}
| |
| − | * y: 12 {{change|bits between them|LSBs}}
| |
| − | | |
| − | Encoded as followed:
| |
| − | | |
| − | ((x & 0x3FFFFFF) << 38) | {{change|((y & 0xFFF) << 26) {{!}} (z & 0x3FFFFFF)|((z & 0x3FFFFFF) << 12) {{!}} (y & 0xFFF)}}
| |
| − | | |
| − | And decoded as:
| |
| − | | |
| − | val = read_unsigned_long();
| |
| − | x = val >> 38;
| |
| − | y = {{change|(val >> 26) & 0xFFF|val & 0xFFF}};
| |
| − | z = {{change|val << 38 >> 38|(val << 38 >> 38) >> 12}};
| |
| − | | |
| − | Note: The details of bit shifting are rather language dependent; the above may work in Java but probably won't in other languages without some tweaking. In particular, you will usually receive positive numbers even if the actual coordinates are negative. This can be fixed by adding something like the following:
| |
| − | | |
| − | if x >= 2^25 { x -= 2^26 }
| |
| − | if y >= 2^11 { y -= 2^12 }
| |
| − | if z >= 2^25 { z -= 2^26 }

| − | The server only sends skylight information for chunk pillars in the {{Minecraft Wiki|Overworld}}, it's up to the client to know in which dimenison the player is currently located. You can also infer this information from the primary bitmask and the amount of uncompressed bytes sent. This packet also sends all block entities in the chunk (though sending them is not required; it is still legal to send them with [[#Update Block Entity|Update Block Entity]] later).

| − | The Cursor Position X/Y/Z fields (also known as in-block coordinates) are calculated using raytracing. The unit corresponds to sixteen pixel in the default resource pack. For example, let's say a slab is being placed against the south face of a full block. The Cursor Position X will be higher if the player was pointing near the right (east) edge of the face, lower if pointing near the left. The Cursor Position Y will be used to determine whether it will appear as a bottom slab (values 0.0–0.5) or as a top slab (values 0.5-1.0). The Cursor Position Z should be 1.0 since the player was looking at the southernmost part of the block.

| − | {{Change||Inside block is true when a player's head (specifically eyes) are inside of a block's collision. In 1.13 and later versions, collision is rather complicated and individual blocks can have multiple collision boxes. For instance, a ring of vines has a non-colliding hole in the middle. This value is only true when the player is directly in the box. In practice, though, this value is only used by scaffolding to place in front of the player when sneaking inside of it (other blocks will place behind when you intersect with them -- try with glass for instance).}}
