Serverbound
Sent to the server when the player attempts to place or interact with a block, or use an item. If a block is changed, this must be followed up by a set block packet!
| Field | Type | Description |
|---|---|---|
| X | Integer | The X block position of the block |
| Y | Byte | The Y block position of the block |
| Z | Integer | The Z block position of the block |
| Face | Byte | The face of the block that's being placed against |
| Block/Item ID | Short | The block or item to be placed |
| (Amount) | Byte | The amount of the item in the players hand |
| (Damage) | Short | The Metadata of the item |
The face can be one of six values, representing the face the block is placed on.
| Value | 0 | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|---|
| Face | -Y | +Y | -Z | +Z | -X | +X |
NOTE
If the face value is 0xFF, the client either failed to place the block, like trying to place it in mid-air without a block to place against, or is trying to use an item, such as a Hoe. For certain items, such as boats, the client will send this packet even if the no reachable block was right-clicked, sending X=-1, Y=255, Z=-1. In those cases, Player Rotation and Player Position and Rotation should be used to determine the correct place to spawn the object.
