Transport Tycoon Forums

Hello all, here now an AI player for OpenTTD named Trans. Project started at Sunday, February 01, 2009 as Fan AI. After looking for this AI name for a few months, finally I've found TRANS, wich is Train_Road-vehicle_Aircraft_N_Ship . Ah.. not must be like that, in fact I really only need a name.
There are many AI's available, and this one is not good enough to beat them

Description:
Trans is an AI for OpenTTD. It try to transporting cargoes from/to any towns and industries using Bus, Truck, Tram, Aircraft and Ship. In the future it would try to use all available vehicles. Current strategy is try to use only one type of industry (if possible) as the destination of transporting cargo named "Cargo Concept", As described in openttd-coop

Short Name ID:
FTAI => Fanioz Trans AI :

Version numbering:
The version number is in YYMMDD format. Latest version was 100307, mean it was released at 7th of March 2010.

Usage:
-Download file (in 2nd post or Bananas-"In Game Content Download")
-Place inside your /ai OR /content_download/ai folder
-Open AI configuration window and you have an options.

note : -"Allow build Rail vehicle" would only take effect once available

The following items are configurable inside game (you've to set the difficulty setting to "custom") ::
- Vehicle to use
- Build Sign
- Dump Log


-type "start_ai trans" in your OpenTTD console

Note:
-You would need at least OpenTTD RC-1 to run
-Please, report the bug(s) or something absurd that build by this AI (attach the screen shoot too)
-Bug report/suggestion/feature request could be made on this thread or http://noai.openttd.org/projects/ai-trans/issues/new

TODO :
- Always fix coding style to follow 'OTTD/Doxygen standard'
- Always Bug fixing
- Be SMART
-----------------------------------------------------------
Trans is an effort to be a transporter.
Build first, improve later, No Final Version.

Note:
this is just a test case, result of 2nd year (1950-1951). Standard generated map with 256*256. Difficulty level = medium. No NewGRF at all. Run on OpenTTD beta2.


Right now, I can't update the content server, because it doesn't recognize well other .nut file.

Unknown file in pack: changelog.txt

Fixing mean, re-tar-ing the file, and force me to use *nix clone, wich is not available now. Maybe later

You sure it's doing that well? I just played a 512x512 Hard map (300k start loan), and Fan AI isn't doing so well. See here:

viewtopic.php?f=65&t=42247&p=772286#p772286

I've introduced IOrder::SkipToOrder() in r15684.
You shouldn't ever call AIEventController.InsertEvent from your AI (I've made that more clear now in the docs).

You're right, the current performance is still need to improve. thank you



Thank you yexo, I 'll try it

Nice work fanioz,

Couple of comments about your pathfinder, it seems to very very bridge happy. Often building bridges where it has no advantage (see the screenshot in your latest post) and I also get some pretty 'interesting' track sometimes (couldn't reproduce at time of writing :/). I had similar problems when I set the cost of building bridges to low, in which case the pathfinder will find building bridges cheaper than building normal tracks.

Besides that I get an error message which is in the included screenshot. Otherwise well done and congrats on including train support .

that is just a typos, and not enough testing time. Thanks Morloth, However the update would be available at least tomorrow,due to version numbering.
About the bridge, I think thats because the neighbour function in path finder doesn't mark that tile as rail buildable, thus the path builder interpreting it as a request to build bridge over an ignored tile.

indeed the pathfinder seems to go quite wrong. Attached is a piece of track your AI just build... I goes all over the place ^^

EDIT: damn, the thing crashed here as well...
Here is the error message.

So, construction style of "good old AI" returns? :)

How do you manage to construct this style of tracks?

_________________
If you need something, do it yourself or it will be never done.

My patches: Extra large maps (1048576 high, 1048576 wide) (FS#1059), Vehicle + Town + Industry console commands (FS#1060), few minor patches (FS#2820, FS#1521, FS#2837, FS#2843), AI debugging facility

Other: Very large ships NewGRF, Bilbo's multiplayer patch pack v5 (for OpenTTD 0.7.3)

Sounds like a big step forward.

However, in last nightly I couldn't find FanAI in the content download window. So I tried in 0.7.0 and found it there, tested it but it did not build any trains. Then an hour later I realized that it might be under another name, but there was no Trans AI in last nightly, but in 0.7.0 there is.

So I guess you have told BaNaNaS that minimum version is 0.7.0. Unfortunately that don't make (later) nightlies able to download it. I use some kind of custom number for PAXLink that I got explained is the same as the OpenTTD version number that GRFs reads. Using this custom number both 0.7.0 and last nightly finds PAXLink. (Unless you really wanted to make it only available for 0.7.0)


Nice to see your AI building rails.

Using 0.7.0 as minimum version works ok, as long as you set the maximum version to "(None)". If it does not show up in a nightly when you do that, please report it as a bug.

yet another request:

your AI seems to like coal (so do I ^^), and it would be pretty neat to have it re-use previous tracks instead of desperately trying to find another way of reaching the same goal.

Another thing, I don't understand why it builds two way exit signals at stations, there is no rational reason for that is there?

also something else (less important, maybe it's just a coincidence), the two trans AIs running build their HQ at the same place, maybe you could randomise this a little.

I really love to play with train building AIs, I do hope this one will become even better! Keep up the good work!

TRANS AI 090418
Revision 59
Fix :: Typos in vehicle detection
Fix :: Now, used combo type signal on rail station instead of exit type to make the train waiting inside of depot.
Fix :: wrong calculation of signal positioning has been corrected
Fix :: Build signal on existing signal will cycle signal type, so must do detect it before build.
Revision 60
Fix :: Issue with send vehicle to depot. (hope it fine now)
Fix :: adjustment little bit at rail path finder
Revision 61
Fix :: Combo signal has a 'feature', fall back to exit signal, and add entry signal too.
Fix :: un grouped vehicle after replacement now bounded to it group again

I hope no more red box crash there, Happy playing

And now, time to answer/respond your suggestion/feedback ..

I've adjusted a cost little bit, still found unnecessary bridge there but not as much as yesterday version. Thanks Morloth.

I could not understand whats wrong with that, as long as the rail is connected, for me it is not wrong, it just a (what to say exactly?) abnormal/ un - natural rail building thanks for testing.
However the crash you're reported has been fixed today.

mmm.. I didn't mean to be the "good old AI". (can't stop laughing right now)
I don't know exactly the reason, but it seem because I gave 2 input for both source and goals. The goals has an estimated_tile routine but not the sources, So the pathfinder is "splitted" before going to the right direction of source. Right now, for me, it is the safest way to connect both side of a station on limited buildable space. Maybe later will change again. Thanks
