Thanks as always for the report, xarick.

I’ve uploaded the fixed version to Bananas as version 102.

Thanks for the report. I’ve released a fixed version, v108.

[Add] Option to Prefer Reusing Existing Roads

Before building new roads, the AI checks whether existing roads can be used. This helps prevent the map from becoming cluttered with too many roads. However, enabling this option may slow down AI performance and increase the likelihood of traffic congestion.

[Add] Option to Prefer Reusing Existing Roads

hooohoh man, that's something i've been wanting to see forever. the inevitable question this raises is of course, could something like this be done for railways? y'know, to finally have an actual network. if middle stations are off the table, that would certainly make up for it. though the catch to that is probably trying to get the ai to route the lines and signal directions tidy enough to pull that off.

on a completely unrelated note, i've been thinking about the idea to have some sort of option to discourage crazy multi header trains. in some cases it makes sense, but the ai always has a thing for having 1830s planet-etc. or other weak locomotives triple upto sextuple heading trains which, never looks right in early starts. i've also sometimes seen it calculate that the most economical option is to have 8 small tank engines hauling a coal train up a hill.

I was thinking the same thing—that track sharing could probably be done with the same system I built for shared roads. If I can overlook issues like track upgrades, speed limits, and trains bunching up, the implementation cost shouldn’t be too high, though the profit performance might end up being poor. That said, it could still prove handy in more complex industry mods such as FIRS.

It calculate the number of locomotives based on factors like gradients, engine horsepower, and cargo weight, but it might be erring on the high side. I’ll revisit the formula when I get some time.

Thank you as always for keeping me informed. I've released the revised version as v113.

I have a feature request.

Could the number of trains/trucks/whatever the Hog is using be limited separately? Likewise, with train lengths and RV counts per service. I can either forbid Hog from a given mode of transport or be swarmed. Likewise, if the train length is unlimited ( or set to a high value ), Hog will happily run 20-tile trains. Regardless of whether it makes sense, and, most importantly, will build 20 tile-long stations even if it does not make sense at all.

It might seem to knee-cap the AI somewhat, but I'd like to avoid excessive swarming with multiple of these on the map.

Also - for purely superficial reasons, nicer company names? Maybe?

I have a feature request.

Limiting the number of vehicles or train lengths is easy to implement. However, I'm not too keen on making the settings for individual AIs too complex. Users probably don't want to deal with the cost of learning how to configure each AI separately.

Instead, I feel a more fundamental solution would be to have OpenTTD itself support per-company settings. That way, it could be used for all AIs as well as to adjust handicaps between human players, making it more broadly useful.

Hi, I have trouble installing on ubuntu linux.

I check the AAAHogEx AI in Content downloading, click download, 253kB gets downloaded but when I reopen the Online Content window, it's unchecked again.

Any idea?

Could you please tell me the version number of OpenTTD you’re using? If it’s not the latest, updating to the newest version might help improve things.

Hello, I am from Indonesia.
Sorry if my English is not good

I have been playing with this AI for quite a while and there haven't been any issues before.

However, after I found out about the game modification by adding NEWGRF, I downloaded all the modules created by Temporal8.
When I started playing, this AI did not begin creating projects until the 5th year. I haven't tried for a longer time.

yeah, I had 13.4, upgrading to 14 helped, thanks
