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.
