This is only passable in one direction, but does not have a signal
or show an aspect in the opposite direction
Add a setting for whether this is shown in the signal UI.
Off by default.
Soon we will make "join game" join the game as spectator first,
so limiting the amount of spectators makes no sense anymore in
that context. Not sure it ever did make sense.
TURN is a last resort, used only if all other methods failed.
TURN is a relay approach to connect client and server together, where
openttd.org (by default) is the middleman.
It is very unlikely either the client or server cannot connect to
the STUN server, as they are both already connected to the Game
Coordinator. But in the odd case it does fail, estabilishing the
connection fails without any further possibility to recover.
In this mode you do register to the Game Coordinator, but your
server will not show up in the public server listing. You can give
your friends the invite code of the server with which they can
join.
This removes the need to know a server IP to join it. Invite codes
are small (~7 characters) indentifiers for servers, which can be
exchanged with other players to join the servers.
This reduced the load on compilers, as currently for example MacOS
doesn't like the huge settings-tables.
Additionally, nobody can find settings, as the list is massive and
unordered. By splitting it, it becomes a little bit more sensible.
We no longer need them. If you want to remove a field .. just
remove it! Because of the headers in the savegame, on loading,
it will do the right thing and skip the field.
Do remember to bump the savegame version, as otherwise older
clients can still load the game, but will reset the field you
have removed .. that might be unintentially.
We won't be able to make it fully self-descriptive (looking at you
MAP-chunks), but anything else can. With this framework, we can
add headers for each chunk explaining how each chunk looks like
in detail.
They also will all be tables, making it a lot easier to read in
external tooling, and opening the way to consider a database
(like SQLite) to use as savegame format.
Lastly, with the headers in the savegame, you can freely add
fields without needing a savegame version bump; older versions
of OpenTTD will simply ignore the new field. This also means
we can remove all the SLE_CONDNULL, as they are irrelevant.
The next few commits will start using this framework.
We often ask people for their openttd.cfg, which now includes their
passwords, usernames, etc. It is easy for people to overlook this,
unwillingly sharing information they shouldn't.
By splitting this information over either private.cfg or secrets.cfg,
we make it more obvious they shouldn't be sharing those files, and
hint to what is inside them.
With std::variant all memory can be figured out at compile time, so the compiler needs to keep track of fewer elements. It also saves out a unique_ptr and its memory management, over a slight impact for resolving a setting.
One UpdateServiceInterval has two parameters to update the service interval for a vehicle type, the other for all vehicle types at once. Rename the latter to help with function resolution for the introduction of variants.
Prior to this change, without realistic breaking, trains would continuously run into the train in front of them. This makes them adjust their speed based on trains in front of them
Prior to this change, trees tended to either cover the entire map like an ancient forest, or alternatively you turn off their growth which breaks industry. Furthermore there are these ugly random tree clumps at the beginning of the game which look like squares on the map someone placed there.
This change adds a new tree placing setting which removes the ugly random clumps and only slightly modifies the initial placement. The actual growth causes trees to bunch up in higher levels as usual but on the lower 4 levels their growth works differently. The number of trees per tile is limited and the trees spread out over a wider area instead of only to the neighboring tile. That spreads them out more and makes for a nicer look.
This also allows cacti to spread, since they can now use that same algorithm and avoid bunching up, but spread as they should.
Prior to this change, the game tended to place towns on mountain tops. Realistic heightmaps had limitations because of this.
This change allows the player to specify that the towns should be generated in the valleys.
