CivilAI

[openttdfan2020]

Mr Pikka,
I just wishing there's new Freight and Passenger Train AI.
Can you make a Passenger And Freight Train AI and name it "Freight&PassengerAI"

[PikkaBird]

Version 33:
Bug fixes:
Ships:
- Fixed crash when checking for ferry route but no ferries are available (reported by 2TallTyler and Timberwolf)

Version 34:
Features:
Trains & Road Network:
- Pre-surveying of routes added, to avoid wasting time trying to path routes which are too long, hilly or wet.
Road Network:
- Building the intercity road network has been re-enabled, with the pre-survey feature.

I didn't understand the bug

(772.95 KiB) Not downloaded yet

One day when I started a game with CivilAI, NoNoCAB and NotPerfectAI on Android, and I absolutely build nothing to just observe their activities, and an error message shown up, though the game remained functional and didn't crash.

I'm observing the same bug, "Couldn't find library 'Pathfinder.CRoad' with version 4".

[PikkaBird]

You'll have to find the missing library and download it too.

If you use the ingame content download, it should download it automatically with the AI, but that may not be a thing on Android.

I'm trying to get CivilAI v34 to fund new industries on a blank map, but the AI does nothing after the game starts.

I've adjusted the following settings:
- competitor difficulty is hard
- maximum loan $4 billion
- primary industry construction is "as other industries."
- industry density is funding only

what else to try so the AI funds industries? is there a game script or other AI that would work? sorry if this is a repost, search gave no solutions

First of all, questions about a specific AI are usually noticed faster if you post them in the thread about that AI.

In general: I don't know about CivilAI but most AI's probably don't handle funding industries. As far as I can remember my AI's WormAI and NoNoCAB don't. Most probably expect relevant industries to be present at game start.

There might be some other AI's that do funding, but I don't think there is a list available which do or don't, so you will have to try that yourself.

Topic is now moved

[PikkaBird]

The question was answered on Discord back when it was asked, ie, it is not possible for CivilAI or any other AI to fund new industries.

v36 adds New Road Types support. Let me know if it works and if I broke anything.

Version 36:
Features:
Road Network:
- Added New Road Types compatibility.
- AI can now build NRT roads.
- AI will upgrade older NRT roads when building routes.

- Various other bug fixes and tweaks.

Version 35:
Bug fixes:
Trains:
- Fixed crash when trying to remove track owned by another player.

[PikkaBird]

Version 37:
Tweaks:
Road Network:
- AI will avoid building vehicles and roads incompatible with default town roads (eg trolleybuses).
- AI will only upgrade roads which it owns.

Maybe this Newgrf will simulate this old abandoned tracks.

When Company's Railway tracks having major problems, cannot to be solved. It will replace the tracks with disused tracks. Just like simulation of abandonment/disusement of railroad grade.

Got a weird crash, the error log doesn't fit.

EDIT: After looking at the code, seems to be an issue detecting a junction. It's walking the maglev tiles which are from another company. In the screenshot, Pink is FastPTPAI, Pale Green is CivilAI with electrified railway.

Great 'city growing' AI. I often play with RVG game script with one can create pax/cargo subsidies for served towns. Can you add some kind 'fulfilling/getting subsidies' to it? Please, please, please.

Had the same issue, nearly identical log so I won't bother posting it, unless it's helpful. I'm just guessing from observation of my own save, but it looks like it culls routes and then tries buying a new train set from a deleted depot in a route that it cut off.

[PikkaBird]

Thanks for the reports everyone, but CivilAI is very much dead; if I were to return to AI coding, I think I would start from scratch.

Thank you for being so open & honest with that. It makes my job of tracking AI's a lot simpler, and better for end users to know definitively. If only all authors were this honest.

I wonder if its worth setting up some programme for GRFs where easily resolved errors are done by me, and released somewhere, just so all AIs (or ones that were good to start with) remain usable until I finally give up on OTTD.

You made a decent AI, PikkaBird, I hope one day you do return and make another one, the more the merrier!

This AI crashes if MAIL is not present (and probably also PASS but that's less readily not present than MAIL...)

In `buyvehicle.nut`, the function `CivilAI::IdentifyBus(silent, intercity, cargo)` is called with `cargo`as `null` if a cargo type is not present. The simplest fix is to just to add `if (cargo == null) return null;` early in the function. With that fix in place the AI will then run fine.
