# Packet 52: MapEnded

> Triggers the native full-GameScene rollover boundary after end-of-round presentation and map preflight.

- **Decimal ID:** 52
- **Hex ID:** 0x34
- **Direction:** S→C
- **Family:** Map sync
- **Status:** Sent
- **Evidence:** Live-verified
- **Wire size:** 1 byte

## Implementation note

The native handler freezes the scene; the revival compatibility hook opens LoadingMenu before the server begins a fresh loader handshake.

## Exact wire layout

The application packet ID is the first byte. The remaining rows are in decode order. Byte sizes exclude ENet headers, wrapper prefixes, LZF chunk framing, and compression effects.

| # | Field | Encoding | Bytes | Purpose | Condition |
| ---: | --- | --- | ---: | --- | --- |
| 0 | `packet_id` | u8 | 1 | Always 52 (0x34). | — |

## Encoding conventions

- `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 documented order.
