Packet ID0310x1F

Building // wire record

ErasePrefabAction

Requests a UGC prefab carve over a bounded block-index range, ultimately using the verified Damage (37) block-destroy path.

C→SHandledProvisionalVariable: 17 + prefab-name bytes

Exact field order

Packet 31 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.

Packet 31 ErasePrefabAction fields in byte order
#	Field	Encoding	Bytes	Purpose
0	`packet_id`	u8	1	Always `31` (0x1F).
1	`loop_count`	i32 LE	4	Simulation-loop stamp used for ordering, prediction, or reconciliation.
2	`player_id`	u8	1	Compact player-slot identifier.
3	`prefab_name`	NUL-terminated UTF-8 string	N + 1	prefab name value.
4	`from_block_index`	i16 LE	2	from block index value.
5	`to_block_index`	i16 LE	2	to block index value.
6	`position`	3 × fixed16 LE	6	X, Y, and Z components at 1/64-unit precision.

Protocol convention

How to read this layout

LE means least-significant byte first.
fixed16 is two-byte sign-magnitude at 1/64 precision.
orientation16 uses the measured 1/8192 orientation mapping.
NUL strings consume their encoded byte length plus one 00 terminator.
Counted arrays repeat immediately in the order shown.
