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.
Game
- Player distance (Settings > Interface, "player-distance"): how far
away another player is still built as a skater, 50 to 1000 m, default
120. Past it they keep their nametag or dot. All the way up shows
everyone. A player already shown stays until 15% further out, so one
skating along the edge is not built and taken down over and over. The
game ran a full skater for every player on the server wherever they
were, which is most of a frame on a full one
- Nametags are always ReSkate's own. The "ReSkate nametags" toggle, the
"Nametag style" button and the nametag-style command are gone; the
game's own nametags are never shown
- Nametag distance ("nametag-distance"): how far away a name still
shows before it becomes a dot, 10 to 500 m. Default 120, was a fixed
150, so by default the name and the skater go at the same distance
- Nametag dots ("nametag-dots"): off hides the dots for far players and
the ones at the screen's edge for players off screen
- Friends' nametags only ("nametags-friends"): only Steam friends get a
name or dot; chat bubbles still show for everyone
Server
- A player out of sight of another (half as far again as the low rate
starts, 255 m by default) is sent to them once a second instead of
five times. On a full server most players are out of each other's
sight, and at five a second each they were most of what was sent
- Rotations are rounded before a pose is passed on, more coarsely the
further away the recipient is: 0.04 degrees within the full rate's
reach, 0.16 within the half rate's, a third of a degree past that,
about 5 degrees out of sight. The pose is still an ordinary one. A
bone that turned by less than a step is the same bytes as before, so
the difference from the reference leaves it out, and the low bits of
the ones that did turn pack away. By distance only: a player the
crowd limit slowed keeps the fine rotations
- A recipient crossing from one precision to another is sent a whole
state of that player, since a difference from a reference of another
precision would carry every bone again
- "net" shows the size of the poses sent at each precision
Profiler
- A function in ReSkate.dll is reported by its address when the DLL has
no symbols. A release build named every one of ours as the nearest of
three exports, so a report could not say which was slow; the
release's symbols name the address afterwards
A player's recent chat lines show as speech bubbles above their skater: newest nearest the head, older lines stacking upward, each popping in with a slight overshoot before it fades. Emotes render as their images, a message that is nothing but a few emotes shows them jumbo, and a message longer than a handful of lines is cut with an ellipsis so one line can never wall the screen off.
Local display options live under Settings > Interface > Multiplayer (on/off, own messages, distance, duration and how many recent lines stack) and the console gains mp chat-bubbles, chat-bubbles-own, chat-bubbles-distance, chat-bubbles-duration and chat-bubbles-history.
The chat panel and the bubbles now share one rich-text module (chat_rich), and a filtered message keeps its emote names: the bad-word mask is applied, but emote tokens are put back from the original before they are parsed.
Skater slot, menu and throwdown fixes; MY MODS rework; lobby parties
Saved skaters (Extension/Customization, Extension/Skater)
- The selected slot, and slots before it, came up as the standard
skater after a start or map change. The game asks for a slot's saved
outfit once per level, and that happened before the cosmetics catalog
could be read. The first selection now waits for the catalog (60 s at
most), and later map changes check against the catalog already read.
- The retry from abdda77 is removed: the record it wrote to is a
temporary on the game's stack, so it could never work.
Pause menu (Extension/UI/NativeMenu)
- ReSkate's entries stopped working after enough map changes: each
level change took new slots in a fixed table of 1024 for the same
buttons. A button now keeps its slot, and a full table hands out the
slot that has gone longest unused.
Throwdowns (Extension/Throwdowns, Runtime/runtime_init.cpp)
- Multiplayer crashed when someone placed a throwdown after a map
change. The event types are freed with the level but were cached for
the process. They are now cleared when a level is left, checked
before use, and looked for again in each level.
MY MODS (Launcher/gui_mods.cpp, gui.cpp)
- Search, a filter and an order; a switch per mod; a menu per row.
- Multi-select with tick boxes, Shift-click and Ctrl+A, and a bar to
enable, disable, move, update or uninstall everything ticked.
Lobby parties (Extension/Multiplayer/Session)
- A lobby is no longer one party. Its host keeps parties the way a
dedicated server does: invite, accept, join, leave, kick, promote,
open and close, with "/p" party chat. The "Lobby party" switch is
gone. Protocol version unchanged (38).
Mod merge (Engine/Vfs), follow-ups to e715b9b
- Files rewritten into the merged patch are tracked by position, so
another mod's added assets no longer shift the lookup.
- Two mods adding different assets under one name is now noted, with
whose copy the maps get.
- mod_merge_unshift_tests compiles with the launcher tests on.
