Hi, forum.
Yeah, as you imagined, I want to add a new symbol. (´・ω・`)
This is a new 3 minutes instant patch based on
this patch.
As you know, you can upgrade your vehicle in Simutrans-Extended.

Railroad geeks know in advance from historical facts that the vehicle has a particular upgrade, but normal people own the vehicle and know it only after the upgrade targets appear.

Hints will be given when displaying "All" vehicles, but it can be difficult to get an answer as to which vehicle it will be upgraded from.
Normally, it should display what the car to be upgrade is upgraded from. Currently it is not possible to know in advance which vehicles in convoy will be upgraded.

But I didn't know how to do it. (´・ω・`)
I can not show the relationship between them, but I thought that I could add more hints.

Check this out


This patch indicates to players the presence of an upgrade prior to purchase.
Please note that the purple bar currently displayed is the upgrade target. The new icon shows the underlying vehicle.
Pink indicates that it is currently available, and Gray indicates that it can be upgrade in the future.
(The possibilities for the future may be wrong if pakset does not have the correct vehicle - a name is described in upgrade [n] but pakset does not have that vehicle.)
code is here
https://github.com/Ranran-the-JuicyPork/simutrans-extended/tree/upgradable-symbolI have not worked on it yet, but this symbol could still be added elsewhere.
Please let me know what you guys think about this.

Thank you.

EDIT: You need the attached pak file to display symbols.
EDIT2: Help text on symbols has been added.
EDIT3: This patch has forked to a new patch.
Please check
here and
here.
EDIT4:The expression "Upgrade is not available yet" is not correct. It will also be gray if the time of appearance is over. It will help if you can tell the correct expression.

We also have the option of preparing a dark blue one.
