Patches & Projects / Re: Options in depots to only ...

Last post by Nazalassa - Today at 10:10:09 AM

Here's a small patch that adds the possibility for textinputs to display placeholder text when nothing has been typed yet, and uses it for searchable comboboxes. In my opinion it is better than showing the current selection until a search query is typed, because it tells the user they can search the combobox. (Otherwise, there is no easy way to discover it.)

For comboboxes where searchability makes little sense, the patch also makes searchability optional. It only enabledsit for the two large ones in the depot window.

Simutrans Gaming Discussion / Re: About single person simula...

Last post by Isaac Eiland-Hall - Yesterday at 01:33:57 PM

It's an understandable thought. I've wished for well over 20 years that Simutrans could be played more like SimCity. Although in those 20+ years, sometimes something gets added. You can actually build individual buildings now, although it's not the same as zoning for Res/Com/Ind and wathing the cities grow. But I will often play in -freeplay mode and use it as a sort of virtual railroad layout, and my goal is to make fun freeways, but also to transport as many goods/passengers as I can (regardless of profit). heh.

And although programmers are volunteers and there's rarely much time to work on requests that don't have broad appeal (especially to those doing the programming), again sometimes things get put in that are useful - like one-way signs for roads. When those got added, we could make two-tile-wide freeways. And things like elevated ways made freeway junctions much more flexible.

So while something radical like playing as someone visible walking around might not ever happen, there is a small chance that if you come up with good ideas, someone might want to implement them. THAT said...... there's usually not a shortage of ideas; rather, a shortage of time/energy to implement them. So it's a balance of expectations. lol. "Probably not, but you never know".

I think this is one of my immature thought. I'm not a programmer, I know even if someone furfil this thought would require a lot of work. I don't really know what would those "pedestrians" do, which allow players have enough energy to play another totally different types of simulation. That would be a brand new game.

It is not possible to show translated texts in the "pak choosing interface"because it is no language selected at this state of the program.

Last post by Octavius - February 24, 2026, 02:49:48 PM

Essentially a back-feeding turning heptagram. I'm not aware of any in real life, but turning pentagrams do exist. There's one in Carbonia (Sardegna, Italy; no longer used) and in Mals (Trentino, Italy). Triangles a.k.a. wyes are more common. I expect this heptagram will be even more compact than a pentagram, but there comes a point where a turntable is the cheaper solution.

In this case the train alternates between doing 45 degree turns, bypassing the exact centre, and straights, going through the exact centre, giving a very complex centrepiece. But if 45 degree turns are acceptable, better make that 36 degree symmetrical turns and turn (!) it into an ordinary turning pentagram.

What would you envision the role of this theoretical single person player? What would they do in the game?

Also, thank you for the message in the "POST HERE" forum - I'm sure it's a strange way to gain access to the forum, but it does make sure that spammers that post spam never have their posts be publicly seen, only by the mods here
