-------

I present my AI - WmDOT (short for William's Department of Transportation).

What WmDOT does is build out the highway network rather than compete with you. It select a capital and builds out the highway network from there, with higher weightings on connecting cities that are higher in population and close together. It can work through a 256x256 map inside a couple of years.

It is also designed to allow multiple instances to work together (each instance selects its own capital/starting point).

Full Buildout

Multiple Instances in action

Available here on or Bananas.

Requires SuberLib v37 and MetaLibrary v8.

Congratulations, always nice to see a new AI! I look forward to trying it out. Looks like your building style makes you a new best friend for Rondje ;-)

I downloaded it from Bananas, it doesn't work 'out of the box'. I had to copy your road pathfinder to the library directory. Could you come up with a solution so that this won't be needed?

And I just downloaded it... Good thing I didn't try it out yet...

By the way - for the revenue stream you can make some airplanes between reasonably sized towns (=accept goods) or if aircraft are disabled, you can make some bus routes between same towns...

Version 3 is up (here and Bananas) that should solve the issue. I've moved the pathfinder to a dedicated file rather than trying to use it as a library. Maybe I can convince them to update the Road Pathfinder in the meantime...

I'm in the process of examining the possibilities... I have a few ideas but both of your suggestions are probably the easiest to program... Stay tuned :wink:

At this point, I mostly wanted to get it out there - the exposure helps move the project along

I've noticed that your info.nut does not contain this code:

Code:

   function UseAsRandomAI()  { return false; }

If you include it, the AI will not be selected by OpenTTD as a random AI. You might want to consider this for AIs which has the main purpose of providing background services rather than operating transport companies.

However, if your plan is to actually operate bus/truck transport on your highways, then I don't see any reason why your AI can't be included as a random AI.

I love the idea of a road making AI, now if only we could implement
toll roads
or a
yearly (monthly) tax from every player so that it could go on forever...

But that would need a complete re-organisation of the game I fear...

cant you make an ai hack in its own money?

Lord Aro · PostPosted: Thu Mar 31, 2011 6:47 am

No, that would be cheating, and AIs can't cheat (apart from the original AI, which is gone)

When loading a game with this AI I get an error:

Thanks for the report Zuu. It seems fixing one problem (rebuilding HQ on reload) has created another (a missing function).

The function in question has been written, so I'll try an post an update tomorrow. In the mean time, destroying the company HQ, and then reloading the AI would allow you to continue.

P.S. Thanks for your SuperLib!

No hurry. Just wanted to make you aware of it.

I'm glad that you found it useful. I've noticed that in the current version Log.Warning does produce an AILog.Error() call. This will be fixed in the next release, but I don't see it as a very important issue, just though it might be useful to know if you try to use it and don't get the expected behaviour.

Version 4 is now up that fixes the savegame loading bug Zuu mentioned.

Upcoming, I hope to do something so it doesn't bog down near so bad on large maps, and eventually to bring food and water to towns to help them grow...

Hello MinchinWeb,

I really liked the idea of this AI when I found it by chance on BaNaNaS, and used it in a game, along with TownCars, for some nice eyecandy and obstacles.
It started out fine building a nice road network between the towns, but later on it began messing up the routes, like you can see on the screenshot. I did use the company change cheat to give both AIs a nice amount of cash to work with, and later used it again to clean up some mess WmDOT made in an area that I needed to build in.

Notice that version 4 (revision 52d) of your AI is used, guess that was the newest version around when I started the game. OpenTTD version is 1.1.0.

Leanden · PostPosted: Mon Apr 18, 2011 7:06 pm

I tried this AI, and it crashed straight out of the box.

Thanks for the reports... My internet is currently down :cry:

so it might be a couple of days before I get the fix posted...

You lucky few - whenever I get WmDOT - I merely get a failed to compile /WmDOT-3/ and a failed to compile /WmDOT-5/.

Which OpenTTD version did you use?

Just for you Roujin, I added a "Cleanup Crew" to WmDOT, new for version 6. It helps, but isn't perfect. You see, WmDOT will (now) only build one road between each town pair, but later on, those town pairs can be across the map. The result is WmDOT will still sometimes build several routes parallel to each other. I'm not sure how to fix the problem more as WmDOT really has no conception of the network as a whole or really the map as a whole. Suggestions on how to improve this are welcome!

Unfortunately, this won't help you with your current game as the Cleanup Crew is run as part of the building procedure.

Below is a sample of the improvement Cleanup Crew makes. It's the same map, run for ~30 year with WmDOT v5 and ~40 years with WmDOT v6.
