Clientbound
This packet is sent to inform the client when a block has performed an action. There are only two blocks that make use this packet: note blocks and pistons.
Noteblock
Note blocks use the packet to indicate they've played a tone. They use the two bytes the packet offers for Instrument and Pitch information.
| Field | Type | Description |
|---|---|---|
| X | Integer | The X position of where the block is. |
| Y | Short | The Y position of where the block is. |
| Z | Integer | The Z position of where the block is. |
| Instrument | Byte | The instrument type. |
| Pitch | Byte | The pitch of the note. |
| Value | Instrument |
|---|---|
| 0 | Harp |
| 1 | Bass |
| 2 | Snare Drum |
| 3 | Hi-hat |
| 4 | Bass Drum |
Piston
Pistons use it to indicate whether they're extended or not and what direction they face. This also plays the piston push or retract sound as needed.*
| Field | Type | Description |
|---|---|---|
| X | Integer | The X position of where the block is |
| Y | Short | The Y position of where the block is |
| Z | Integer | The Z position of where the block is |
| State | Byte | false for extending, true for retracting |
| Direction | Byte | The direction the piston extends/retracts to |
The direction matches the lower 3-Bits of the metadata values that're used for pistons as described on the Blocks page.
| Value | Direction |
|---|---|
| 0 | Down |
| 1 | Up |
| 2 | East |
| 3 | West |
| 4 | North |
| 5 | South |
MISSING
A lot of this still needs to be tested. I'm unsure if this just plays the sound or if this is also responsible for playing the piston extend/retract animations!
