Packet 97 wire layout
The first byte is the application packet ID. The rows after it appear in decode order. Sizes exclude ENet headers, the outer wrapper prefix, LZF chunk framing, and compression effects.
| # | Field | Encoding | Bytes | Purpose |
|---|---|---|---|---|
| 0 | packet_id | u8 | 1 | Always 97 (0x61). |
| 1 | loop_count | i32 LE | 4 | Simulation-loop stamp used for ordering, prediction, or reconciliation. |
| 2 | position | 3 × u16 LE | 6 | Raw X, Y, and Z voxel coordinates. |
| 3 | ugc_item_id | u8 | 1 | ugc item id value. |
| 4 | placing | boolean u8 | 1 | placing value. |

How to read this layout
LEmeans least-significant byte first.fixed16is two-byte sign-magnitude at 1/64 precision.orientation16uses the measured 1/8192 orientation mapping.- NUL strings consume their encoded byte length plus one
00terminator. - Counted arrays repeat immediately in the order shown.
