Other players' skaters and skateboards showed none of the game's skater
effects: not the trail or fire a costume or deck comes with, and not the
sparks, dust and puffs of a skater touching the world.
Costume and skateboard effects. The game gives another player's skater and
skateboard the right effect sets by itself, but builds them before their
outfit is on, so nothing showed. They are now built again half a second after
the outfit is applied. An always-on effect that a skater's item puts on the
skateboard's wheel joints (the Ghost Skater trail) follows the skater's own
copy of those joints, which only this player's skater keeps up to date: for
other players it is taken out of the skater's sets and built on their
skateboard, which has the same joints.
Contact effects. They come from a skater touching the world, which only
happens in that player's own game. Each game now captures its skater's
contacts (position, velocity, surface normal, surface material) and sends up
to three a tick in a new unreliable packet, PacketKind::effects. Other games
play each through the game's own function, so the effect is still chosen from
the surface and the speed. A contact is shown as late as that player's poses
are, only within 30 m of their skater, and only for a material the level's
table has: the game reads that table without a bound.
Server. A dedicated server relays effects packets to players within 150 m of
the sender, at most one packet a tick from each player. New setting
players.sync_effects (default true), console and admin command
"effects on|off". Off: the server relays none, and the roster tells games
neither to send their contacts nor to build other players' costume and
skateboard effects. Player-hosted lobbies relay through the host and always
share them.
The roster carries one more byte for the setting. Still protocol 45, which
has not been released.
New console command "mp effects": what has been captured and played, and why
the last contact was refused if one was.
Server: remove players who have been away too long
A dedicated server can remove players who are away from their game.
- "afk_kick_minutes" in the config's "players" section: 1 to 1440, or 0
(the default) for never. "afk-kick <minutes>|off" from the console or an
admin; a change is saved and applies at once.
- Away is doing nothing a player at their game does: not moving or turning,
not speaking, not sending chat, and not placing, moving or removing an
object.
- A minute before the limit the player is told in chat; at the limit they
are removed with a message saying why and that they can join again. The
log has an "[afk]" line.
- Admins are never removed for it. The time starts once a player's game has
loaded the map, and starts over after a map change and when the setting is
changed.
Server: object scaling can be turned off
A dedicated server can stop players resizing the objects they place.
- "allow_object_scaling" in the config's "players" section (default true),
and "object-scaling on|off" from the console or an admin. A change is
saved and applies at once.
- Off: the server shares every player's objects at their own size, whatever
that player's game sent. Admins can still resize theirs, as with the
object limit.
- The roster tells each game. In the park editor of a player on such a
server the SCALE mode is not offered, its Y shortcut does nothing, the
scale box is disabled with a note saying why, and what is placed or edited
is its own size.
- An object resized before the setting was turned off is its own size for
everyone else straight away; its owner sees it resized until they edit it.
Conflicts in Server/server_host.cpp: main changed the command code after this
branch moved it to Server/server_commands.cpp. The moved copy now has what
main added since: the "chat-color" command, "park random", and its line in
the help text.
