No protocol change: a server built from this still takes 1.1.4 players.
Server: what each player is sent
- A crowd limit: each player is sent at most crowd_budget poses a second
(default 600, 0 for none; "crowd <n>|off"). Everyone at 5 a second at
least, the nearest at the full rate, the next nearest at 10. Before,
everyone within full-rate distance was sent at the full rate, which a
crowd of 40 turned into more than a connection carries
- A skater's sound goes only to players within the full-rate distance,
and in a crowd only from the nearest; it went to everyone
- A player who joins, or arrives after a map change, is shown the others
about seven a second, nearest first, and none while what they were
already sent is still on its way. Before, every outfit and every
stream went at once (and to everyone at once after a map change)
- Whole pose and sound states every 8 seconds instead of 2, on the
source's own clock, and slower pose rates sent on that clock too, so
recipients share one patch and compression (DeltaCache) instead of one
each. The settings survive a map change
- Object updates wait for a connection that is behind
Server: Steam connections
- send_rate (default 900 KB/s, "rate <KB/s>") is set as both Steam's
minimum and maximum, for open connections and each new one. With only
the maximum raised a connection stayed at Steam's 256 KB/s; set high,
what was lost was resent until the connection was full of resends
(about 1.1 MB/s reaches a player through the relays)
- A 4 MB send buffer, and a refused must-arrive message no longer ends
the player's session at once: 15 seconds of refusals do (30 for object
updates). A full queue used to drop everyone who was behind together
Server: seeing what is going on
- "net [player]": every connection's ping, delivery, queue and rate, the
traffic by kind (poses, sound, voice, outfits, objects), who uploads
most, and how busy the server's loop is
- A [network] line in the log every minute
- A leave or failed join says how it ended: closed by the player's game
with Steam's reason, connection lost, or closed by the server and why
- The queue time no longer prints Steam's "unknown" as a number
Server: other
- Reserved slots: reserved_slots and reserved in ReSkateServer.json, and
the "reserved" command; admins always have one
- The speed check flags a game at about 1.5x and over (was 1.06x), and
tells only that player; for the admins it is in the log
Game
- A remote skater with no pose for a second stays where it was for up to
eight seconds instead of being destroyed and rebuilt three seconds
later. On a busy server one slow frame did that to many players at
once, and the rebuilding made the next frames slower still
- Every waiting message is read each frame (at most 128 were)
- On an official server the role tags (Dev, Staff, Homie, Creator) show
for every player, not only the few the game is connected to directly;
community servers keep the old rule
- The server browser searches Steam at most every 15 seconds (45 after an
empty answer) and keeps the last list for 15 minutes when Steam returns
nothing, up from 2
- The game's own connections send at up to 900 KB/s
Limit how many objects each player can place (protocol 43)
- Servers and lobby hosts set how many objects each player may have
placed: object_limit in ReSkateServer.json and the "objects" command,
"Objects per player" in the host options. Default 100; 0 is no limit
- The host and a server's admins are not limited
- At the limit a player's game refuses another object, from the native
object tool and the park editor, and the menu shows how many they have
placed
- Enforced by the host or server, which shows everyone no more than the
limit of each player's layout; objects already shown keep their place
- The limit travels in the roster, which takes the protocol to version
43: builds before this cannot join sessions with builds after it
- The protocol tests link again (the server browser needs the identity
lists since the official servers change)
- Mod merge: rebuild a merged bundle's chunk metadata the way the game
writes it (one record per chunk, in chunk GUID order), so costumes
from different mods built on the same game costume keep their
textures and meshes
- Merge audit checks that layout, and there is a new unit test for it
- Server names: only letters, numbers, spaces and - _ [ ] ( ),
1 to 64 characters; the server browser hides servers with other names
- New Centrix tag from the backend's "centrix" list: blue and white
name, badge and item animation, ranked after Dev and before Creator
- Read Dev / Creator / Homie Steam IDs from api.reskate.dev instead of the hardcoded list
- Creator (red) and Homie (gold) tags and hoodie/board colours; Admin tag is now pink
- Global bans: lobby hosts and dedicated servers turn banned players away
("global_bans": false in ReSkateServer.json opts a server out)
- SPECIAL menu page for listed players to hide their own tag and items
- Fix hoodie and board keeping the animated colour after the animation turns off
- Multiplayer protocol 39 -> 40
Follow-ups to the trainer (PR 37), and one multiplayer change.
Off until asked for (Extension/Trainer)
- The jump read-out and the LB+RB controller shortcuts start off. Jumps
are logged only while the read-out or telemetry recording is on, and
trick launches only when the trainer scaled them. A saved trainer.json
keeps what the player chose.
Memory search on demand (trainer.cpp, trainer_classes.cpp)
- The search for the game's tuning classes reads all writable memory.
It ran for every player after a level loaded, and up to seven times
when it found nothing. It now runs only when a class value or the flip
speed is not the game's own (the player's, or a host's they skate
with) or the EVERYTHING list is open, and at most three times a level.
- For those players it runs again on each level, which brings fresh
copies; a search from an earlier level used to count as done.
Guests under enforced physics
- A guest is locked by the session's enforce setting, from the moment
of joining (Engine/Game/Multiplayer/session_physics.h), not by whether
the enforcement status text was set yet.
- A guest's class values no longer come back after a map change.
The host's whole setup reaches its guests (protocol 39)
- Only Gameplay/SkatePhysicsTuning travelled, so a host could push,
sprint or jump further than the guests it held to the game's own.
- New packet physics_extras (30): the host's class values, trick
multipliers and auto push (trainer_session.h), sent when they change
and to players who join later, taken from the host only. A dedicated
server's are the game's own and it ignores the packet.
- Under enforcement a guest's own trick multipliers stand down for the
host's, whatever the boosts switch says. With enforcement off nothing
changes.
- A guest refuses bytes that are not an encoding, holds values to the
trainer's own ranges, and leaves out class values written for another
game build's table.
- protocol_version 38 -> 39: released versions disconnect from a peer
that sends a packet they cannot decode.
Out-of-view players are posed every frame again (Session/session.cpp)
- Players outside the camera's view and past 8 m were sampled at 20 Hz
(b763631). The game's replays record each skater as it stood every
frame and their camera looks anywhere, so those players moved at
20 Hz in replays. Removed; the distance rule (20 Hz past 200 m, 10 Hz
past 350 m) stays. This gives back the client-tick time it saved on
busy servers.
Cap outfit packets and stop dropping recipients when a relay cannot be
built. Add per-player relay limits for outfits, skater sound and voice,
and a back-off for Steam IDs that keep failing to join.
Throwdowns: only participants can write rows, turns and scores; a copy
that fails to spawn no longer blocks the others.
Throttle remote skater and skateboard re-creation, cap remote objects
per session, and show developer and friend marks only for identities
Steam vouches for. Route all connections through Steam's relays.
Dedicated server: validate map changes, clean player names, keep vote
cooldowns across reconnects, and cut ban labels on a character boundary.
Two follow-ups to the Linux server support in #6. Both are Linux-only, so
neither reached a Windows player.
Session codes
- nonce()'s fallback for a container with no /dev/urandom read
"i < 4 && !value", which ended the loop as soon as the first round
produced anything: one round of sixteen bits instead of four. Over
200k draws that is 62k distinct codes with a ceiling of 0xffff, rather
than 200k across the full range.
libsteam_api.so
- It was fetched from a mirror's main branch with no hash, by CI and by
the script every server operator runs, and it is loaded into the
server process. A branch name is whatever that branch holds on the day
it runs.
- Pinned to mirror commit df2baabf574a and checked against its SHA-256
(385840 bytes, eb2dd015...). The size and export checks already there
catch a wrong file; a hash is what catches a swapped one.
- --sdk-url still overrides the URL and drops the check, since a
different URL has a different hash; --sdk-sha256 keeps it.
