I have pushed a update to fix some of the issues- please could you post in the bug thread in the discussions details of any problems you are having, I can only fix if i have enough information

why does it keep failing

The mod keeps crashing all the time when I try to improve the bus lines, it doesn't let me and now when you build new bus lines, only one stop is connected and the buses start going around in circles.

also the City bus planing seems to be broken. it always buys 2-4 Big buses times 3 routes per city even it its only 250 people. each line is lossing min 1 mil pls setup cost is insane high

so an info for people new to this mod: the AI Builder only uses an industry if it is producing. so an Crude oil well will always be visible but the Refinery is only visible for the AI builder when it gets Crude and "could" produce Oil.

the report problem lines tool just completely doesn't work there is multiple errors one with the vehicle util and some other ones

looks like i get a recurring file location error on many different action. like as if it was the address of the game folder or sub folder not found. everything seem to work tho. and next to the ai menu in the bottom i get D: like my address of my drive that weird.

I think passenger line sharing should be an option
Also idk how to word this but say if you've built a line with the route planner and then want to have a branch I don't want it to make an entirely new line like it does currently
Does that make sense?

I also am noticing several other industries it doesnt recognise

The first time I tried this it was able to make a route to a town and now it wont let me and it also doesnt seem to recognize oil and fuel.

@okeating it would be cool if you connect industry to town, also there's an error with connecting to copper mines that causes a crash for me

I have an error to report that the copper mine causes a crash for me

French please

@imam_vov i get those as well but that doesn't stop me to retry it again on wich it works fine.
but when i use train and refresh game freezing and shuts then off.
@Okeating please fix that including any parts that involves it.

Error in lines:

Have deleted and installed AI builder again. But not helping.

This sounds AWESOME! I can't wait to try it on my next map!

Hi, after launching a construstion the game does not reset to play. I can click on the cities to continue building but it's like in constant pause.

Hey, I have an issue or maybe im not understanding this mod.

When ever I try and build something it either takes ages to start (initialling) or never completes. If I use Global it starts immediately but never finishes. If i use the within circle mode it never starts.

Should it take this long. I also cant place or remove anything whilst this process is happening.

Any help would be awesome

@FrozenHands try it now I have pushed an update

is there a way to either make the signals go in the opposite direction or turn them off when building Railways.

The mod is broken and can't create bus lines between cities, while the road is available.

nachtrag es geht gar nix

brauche Hilfe es zeigt an An error occurred while excuting bulding Complete route

@op there is a thread, i will update it with the errors i receive

@WingusMcDingus could you start a thread in the discussions above? It would be useful to get some more information and clarity about what is working and what is not working for you.

@Einstein, when I was testing this with some of the industry mods, I found that resources would end up flowing all over the place if vehicles (particularly trucks) at "auto load". I did want use the line load filter to solve this, but there is a bug in the api that won't let this be set, so instead I locked the cargo type. I could make a checkbox to opt out of this feature in the params screen.

scripts dont like creating new intercity bus routes, has trouble analyzing train stations with multiple lines, cant create highways, cant create air routes

Lines are created with vehicles only being able to do the resource we define first, but there's often a chance to bring back a non-empty haul, which we could edit manually, but because the trucks are define with a single resource I usually need to replace all vehicles for the same vehicle to unlock all other resources options. Is this expected?

im still getting bugs on trying to build tram/bus lines, something on line manager.lua 3220, an error in ai_builder_script.lua 4152 and 4315

I'm wondering if the error only occurs if debug mode is not active.

Apologies, I have just pushed an update, the check lines has been fixed, the global assignments have also been fixed (I don't understand why I don't encounter this error myself)

Most recent update completely bricked mod's ability to check lines, returning an error whenever analyzing lines

I am also facing an error while trying to build a rail connection between two cities. I have not been able to get this to work at all. https://paste.pics/7eaee2ec8a24f8172bb412393d50b9a8

I have pushed a new version that should fix some issues, @Einstein could you recheck if it is an issue, if it is then yes it would be helpful

I asked AI to build me a highway between two towns - it built me a fookin NURBURGRING lmaoo

This is a great mod, although shipping is broken and airports are regularily build on streets.

Is it possible to deactivate passenger line merging? I dislike having these super long lines, and instead would prefer point on point travel.
I'd also really like an option to force create a completely new separate line that doesn't use preexisting railroads as this causes massive unsolvable traffic jams on short distance industries with high production.

Nice work!

The auto-detect vehicles is not working, playing with European the script is adding Asian vehicles to start with. Not a huge issue, but would be nice to get it fixed.

What should I do if I want to replace an early truck delivery by a train one? I tried deleting all the old infra and lines, let transport go down to 0, but it won't suggest me as a train (or truck) option anymore.

I'm also getting a crash when trying to build a specific route into a city where another good is already delivered. If I delete the first good truck stop then it builds it. Do you want the save game/logs to check?

incredible work thank you. very impressive codding/modding

Sooo this is a bit of an overstretch but what about AI field placement?

how do you use it
