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.
Mesh streaming pool (fixes loading crashes on older GPUs)
- 1.0.0 forced MeshStreaming.PoolSize to 3.5 GiB on every card. An RX 580
crashed while loading with DXGI_ERROR_DEVICE_RESET, and the oversized pool
is the likely cause. The pool is now a quarter of the largest hardware
adapter's dedicated video memory, capped at 3.5 GiB; cards of 6 GB or less
keep the game's own 520 MB. The card, its memory and the chosen size are
logged once at startup.
Remote players (busy servers)
- Transform interpolate is inline plain arithmetic: 22 -> 5.8 ns per joint.
It was 4% of a busy server's client frame, since every player within
200 m has the whole skeleton interpolated every frame.
- Players out of the camera's view and more than 8 m away are sampled at
20 Hz, like far players. Their position still updates every frame for
collision, sound and nametags, and a player coming into view is sampled
that frame.
Expression hooks (run for every expression the game executes)
- No profiler zones in the expression hooks: taking a sample switched them
on, inflating the very samples that measured the hooks.
- The throwdown lab pump does one sorted lookup of the running graph and
skips everything else for graphs it doesn't watch (graph_throttle gets
throttled_graph for this).
Settings and memory reads
- Script gameplay-setting and native-setting gets are served from small
per-thread caches, keyed on the asset/key address, its first 8 name
bytes and a new profile::Store::changes() counter, instead of a store
lookup each call.
- Per-frame reads in the client tick, native settings and population
controls use memory::peek instead of ReadProcessMemory.
- Script error logging probes each argument pointer once.
Launcher
- "Close the launcher when Skate starts" now hides the launcher and exits
when Skate.exe does, instead of exiting as the splash opens. Outside a
Steam library, Skate's protection closed the game (TerminateProcess 0x32)
when the launcher exited during startup; players confirmed turning the
setting off avoided it.
- STATUS tile warns when Steam isn't open or signed in that PLAY starts
offline as Unknown Player (hidden when Offline mode is chosen or while
launching).
- Setting description updated to match.
Startup interventions (20260929)
- exit_return 0x87755f2 -> 0x87fe7fb: the last LEA RSP,[RSP]; JMP stub
before the PUSHFQ / LOCK CMPXCHG routine, as 0x87367cf was in 20260908,
and the return address player logs show. Only enforced once a frame site
is armed; this build's protector has no equivalent rep stosb frame clear.
Client frame cost (profiled 2026-10-02)
- Transform interpolate is inline plain arithmetic (~1% of an MP frame).
- Script gameplay-setting and native-setting gets are served from small
per-thread caches keyed on asset/key address, name prefix and a new
profile::Store::changes() counter, instead of a store lookup each call.
- Hot-path reads in client tick, native settings and population controls
use memory::peek instead of ReadProcessMemory.
- Script error logging probes each argument pointer once.
