| |
| − | | How many bits per block in Data Array. If 0, the Palette Length and Palette fields are omitted and the global palette (with 13 bits per block) is used.
| |
| − | |-

| |
| − | The global palette encodes a block as 13 bits. It uses the {{Minecraft Wiki|Data values#Block IDs|block ID}} for the first 9 bits, and the block damage value for the last 4 bits. For example, diorite (block ID <code>1</code> for <code>minecraft:stone</code> with damage <code>3</code>) would be encoded as <code>000000001 0011</code>.

| − | ==== Spawn Player ====
| |
| − |
| |
| − | This packet is sent by the server when a player comes into visible range, ''not'' when a player joins.
| |
| − |
| |
| − | This packet must be sent after the [[Protocol#Player List Item|Player List Item]] ([[#Play|Play]], 0x38, clientbound) packet that adds the player data for the client to use when spawning a player. If the Player List Item for the player spawned by this packet is not present when this packet arrives, Notchian clients will not spawn the player entity. The Player List Item packet includes skin/cape data.
| |
| − |
| |
| − | Servers can, however, safely spawn player entities for players not in visible range. The client appears to handle it correctly.
| |
| − |
| |
| − | When in online-mode the UUIDs must be valid and have valid skin blobs, in offline-mode UUID v3 is used.
| |
| − |
| |
| − | For NPCs UUID v2 should be used. Note:
| |
| − |
| |
| − | <+Grum> i will never confirm this as a feature you know that :)
| |
| − |
| |
| − | In an example UUID, <code>xxxxxxxx-xxxx-Yxxx-xxxx-xxxxxxxxxxxx</code>, the UUID version is specified by <code>Y</code>. So, for UUID v3, <code>Y</code> will always be <code>3</code>, and for UUID v2, <code>Y</code> will always be <code>2</code>.

The server only sends skylight information for chunk pillars in the 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.

| |
| − | |}
| |
| − |
| |
| − | In normal operation (i.e. placing a block), this packet is sent once, with the values set normally.
| |
| − |
| |
| − | The Cursor Position X/Y/Z fields (also known as in-block coordinates) are calculated using raytracing. The unit corresponds to one 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 0–7) or as a top slab (values 8–15). The Cursor Position Z should be 15 since the player was looking at the southernmost part of the block.
| |
| − |
| |
| − | This packet has a special case where X, Y, Z, and Direction are all -1. (Note that Y is unsigned so set to 255.) This special packet indicates that the currently held item for the player should have its state updated such as eating food, pulling back bows, using buckets, etc.
| |
| − |
| |
| − | Special note on using buckets: When using buckets, the Notchian client might send two packets: first a normal and then a special case. The first normal packet is sent when you're looking at a block (e.g. the water you want to scoop up). This normal packet does not appear to do anything with a Notchian server. The second, special case packet appears to perform the action — based on current position/orientation and with a distance check — it appears that buckets can only be used within a radius of 6 units.
