Server config:
- Written in sections, in reading order: server, access, maps, players,
anti_cheat, network, votes. A config from an older version, flat and
under older names, is read as it is and written back this way on first
start; only settings that are really new are reported as new.
- Renamed: no_bail, noclip, boosts, parties, voice_chat to allow_*;
global_bans to use_global_bans; welcome to welcome_message; speed_check
to speed_hack; score_check to modified_scoring; score_allow to
allowed_scoring_mods; map_pool and map_rotation_minutes to maps.pool and
maps.rotation_minutes. Console and admin commands are unchanged.
- Bans are kept in data/bans.json beside the config. A config that holds
them has them moved there; a bans file that cannot be read stops the
server from starting.
- Reserved slots are one list, "reserved_players_slots": a slot is kept
for each listed player who is not on. "reserved_slots" and the
"reserved slots <n>" command are gone; admins may take a kept slot but
none is kept for them.
- "tps" is no longer in the file: dedicated servers run at 20.
- "bone_scale_limit" is 1 by default: resized body parts are off unless a
server allows them.
- New: "pack_ms" (10), how long Steam may hold a message to pack it with
others; "finger_distance" (25); "steam_debug", which logs what Steam's
networking says, for connection faults.
Poses and skater sound between a dedicated server and its players use new
formats. Lobbies and the links between games are unchanged.
Poses (pose_codec.h, pose_batch.h):
- A pose is rounded once (rotations to 0.08 degrees, positions to a
millimetre) and sent as its differences from a pose of the same player
the receiver has acknowledged. Several players' poses share one message.
- The receiver acknowledges messages once a tick; the sender builds only on
acknowledged poses, or on the whole pose it sent reliably. Loss costs the
poses in that packet and nothing more.
- Fingers are not sent to players further than "finger_distance" (25 m).
- Games upload their own poses the same way, and the server acknowledges.
- About 300 B a pose at full rate against about 660 B before.
- The server no longer rounds rotations by distance: it saved little.
Sound (sound_codec.h):
- Each sample is sent as what changed since the one before, numbers rounded
to 1/1024. One reliable message a tick carries every skater a player can
hear. A stream is sent whole at its start and every two seconds.
- About 106 B a message against 368 B before, on a recording of real play.
Direct connections:
- "connection": "relay" (default) or "direct", with "direct_address" and
"direct_port". A direct server listens on UDP and is listed with its
address; players still sign in through Steam.
- Games connect straight to servers that offer it and fall back to the
relays after 5 s. Setting and "mp direct-connections" to turn it off.
Server:
- "bone_scale_limit" is 1 by default: resized body parts are off unless a
server allows them.
- Logs Steam's relay network status at start-up and in "net", and watches
the Steam sign-in.
- "pack_ms" (10): how long Steam may hold a message to pack it with others.
- "steam_debug": logs what Steam's networking says, for connection faults.
- "relay_everything": sends poses and sound through the server even between
games that have linked, for testing with few players.
- "net" shows pose sizes by rate, the share sent without fingers, and whole
poses sent.
Game:
- Only ReSkate's nametags are shown; the game's own are removed.
- "mp pose-dump <seconds>" records the local skater's poses and sound.
Tests: pose_codec_tests covers exact round trips, chains of differences,
held fingers, damaged input, the sender and receiver over a link that
delays, loses and reorders, and the sound format; with a recording as its
argument it prints sizes on real play.
Protocol 44: servers and games must both update.
Server browser
- Official servers (the backend's "official_servers") sort first and are
drawn in ReSkate blue
- Servers Steam friends are skating in sort next, drawn in green with the
friends' names; searching a friend's name finds their server
- A player in a session they joined can join another server straight from
the list; hosts still end their session first, and a Steam friend's join
offer never replaces a session
- Joining a dedicated server from the list records it as the player's
public session, so friends see it and the row shows HERE
- Blocked servers (the backend's "blocked_servers") are hidden and cannot
be joined, by code either
- When the backend sets "server_tokens_required", dedicated servers that
signed in without a login token are hidden, except on the player's own
network
- A search that gets no internet list from Steam keeps the last list for
two minutes, and waits six seconds before treating it as empty
Roles
- New Staff tag from the backend's "staff" list: green name, badge and
item animation, ranked after Dev
- Staff can pick a rainbow for their items on the Special page; it is sent
as a solid colour older builds can show, so the protocol is unchanged
Dedicated server
- steam_token: sign in with a Steam game server login token and keep the
same Steam ID every start; empty signs in anonymously as before
- A listed server without a token says so at startup, and when the token
rule starts or stops hiding it
- Linux servers update themselves from the release's "server_linux"
tarball, with the machine's curl and tar, pinned by SHA-256, and carry
on in the same process
Launcher
- Only create the MiniDumpWriteDump API-set shim under Wine/Proton
tag_text dropped a trailing lead byte even when its character was whole, so
"Skate Café" was listed as "Skate Caf". The browser shows the tag name until
the server answers a query, so hosts without a forwarded query port kept it.
