ChooChoo, a train network AI

[1009]

And isn't the second one just a crossing where it removed the sideways? Or does it build different stuff then? n_n

[WWW]

Playing a game with this AI, I found that it will construct trains longer than it's stations, and that trains will trap themselves as a result.

Can't show you any pics though.

I don't have a screenshot but my AI once did this with a railway line.

Something went wrong in the screenshot Don't know what, fast-forwarded a game for 40 years. Also, it didn't sell the train in the lower right after years of losing money. Too bad your AI didn't really perform well in this map, maybe because of the hilly terrain and high sea level. Other than that it seems like a fine AI, good luck developing!

While updating the head post on common tags in use I noticed that for ChooChoo you have forgot to put a comma between the two tags that you have given.

So instead of specifying the two tags "train" and "save/load" you have created a new tag "train save/load". When users search for more than one tag you can probably see that this will become a problem.

It is, but it should have flipped or removed (depending on version) the exit signal to allow trains to pass once it connects the crossing to its destination.

Ah, I thought they were whitespace separated. I'll go fix that right away

I clicked the "X" in that window in the screenshot brainwashed by it that I was playing OpenTTD!

Does ChooChoo support newgrf's? Cause, mine keeps crashing right when it puts down its stations and depots. Build on town owned roads is on, max station spread is 50, and it has plenty of loan left always. Seems to me it doesn't know it can't build 20 tile bridges due to a grf.

That's not a crash, that's the display of a try() - catch()-sequence. It just continues to try and build stuff.

It did crash, I got a popup for it..the log ends with "datehere: unexpected error".

that really doesn't help
the AI author needs the whole debug screen

[Vemarkis]

I gave the whole debug screen in the 2 screenshots above.

[Lord Aro]

then why did you post again?

[planetmaker]

then why did you post again?

Why don't you read the thread in sequence and postings entirely. It might answer your question

Trains in ChooChoo almost never use "full load" (Except first train).
It result in very unprofitable trains.
Trains can do sth like it:
station A - unload + full load
station A - unload + load available

[Michiel]

Thanks for the bug reports, guys! There are grfs that limit bridge length, too? No, it doesn't support that, and it's probably not going to. At some point, you're just not playing the same game anymore

True, but full load can result in trains staying in a station for months, clogging up the lines, which is also bad. Also, I'm not trying to maximize income. As long as it makes enough money to stay alive and expand, it's doing fine.

That's not a crash, that's the display of a try() - catch()-sequence. It just continues to try and build stuff.

Close - that one is actually fatal I've set the maximum bridge length to 20 and apparently it discovered there's no bridges available that can actually support that length.

Edit: "I'm trying" -> "I'm not trying"

[1009]

Cool I'm just using the library pathfinder though, but it can use some debugging aids in the form of signs showing what it's doing, that's for sure.

Dustin, sorry for hijacking your thread

Still, your AI fails on building paths now and then but since I don't have a clear idea of when it happens... .

Can you not make it a variable the user can change? Denver & Rio Grande has a setting for that, I think it would solve the issue completely.

<Hijack>Wow, I didn't realize that setting would actually be useful for anything.</Hijack>

Me neither But it's not the pathfinder (I've checked), it's my own code. At the moment, it's "in the shop" and even more broken, so I'm some time away from the next release.

Can you not make [maximum bridge length] a variable the user can change? Denver & Rio Grande has a setting for that, I think it would solve the issue completely.

That's a great idea. Planned user settings so far:

- max. bridge length
- number of bootstrap lines to build
- enable/disable debugging signs
- spending habits, like D&RG's "fiscal restraint"

<Hijack>Wow, I didn't realize that setting would actually be useful for anything.</Hijack>

Argh! Retaliatory thread hijack!
