A dedicated server that rotates its maps can now ask players where to
go next instead of taking the pool's next map.
Server
- maps.rotation_vote: when the timer runs out, a vote between three
maps drawn at random from the pool, "Random map" and "Stay here".
The most votes wins, a tie is drawn, and with no votes it is the
pool's next map. It ends early once everyone has voted.
- maps.rotation_vote_seconds (10-120, default 30) and
maps.rotation_extend_minutes (0-240, default 15; 0 leaves "Stay
here" out).
- maps.rotation_announce: a card when the map has 10, 5 and 1 minutes
left.
- The vote's maps are drawn a minute ahead and sent to games
(PacketKind::next_maps), so their pictures are ready when it opens.
- /vote extend: a built-in vote that gives the map in play
rotation_extend_minutes more. On by default (votes.extend_map), and
only runs while the maps are on a timer. "extend" is now a reserved
vote name.
- Console: rotation vote on|off, rotation announce on|off,
rotation stay <minutes>|off, rotation extend [minutes],
votes extend ..., vote extend.
Game
- The vote opens as a popup in the middle of the screen: a tile per
answer with its picture, name, share of the votes and count. It
holds input as the map download card does, and works with a
controller (D-pad, A, B), the keyboard and the mouse.
- Pictures: a mod map's icon from its folder, or from Thunderstore
when it is not installed; the game's own maps show their loading
screen picture, cut to its middle square. "Random map", "Stay here"
and a map without a picture are drawn as shapes.
- Older servers and polls are unchanged: the vote is a poll, so it can
still be answered with /1, /2... in chat.
Protocol 50: games and servers both need this build.
