Transport Tycoon Forums

• North America themed. Prefers the NARS train set. (But supports default and 2cc).
• Two way tracks.
• Train management.
• Remove stations for closed industries.
• BSD License
• Completely custom pathfinder that is much faster than the default rail pathfinder.
• Minimal terraforming.
• Mostly Non-network style connections (sort of like the Old AI).
• Pathfinder uses 3 sub-pathfinders.
• Main pathfinder is "as the crow flies" CrowPathFinder that heads directly for the goal (watching slopes to ensure tracks can be built). This is the key to speed since most of the time this is all you need.
• Bridge and Ant pathfinders are secondary. Bridge just tries to bridge gaps the crow detects. If bridge fails the ant (slow and similar to A*) wanders around trying to find a path.
• Poor to decent code. I was more interested in making it work than making the code very good.
• There are settings for a "verbose" mode so you can see the pathfinder in real time.
• 2cc compatible, but don't expect it to turn a profit on rough or hilly maps with default costs. The engines in that set are really expensive. Turn up fininacial restraint to high for best results.
• Reuse of consumer stations for mini networks.
• Untested with non-default industry grfs.
• Lots of user tweakable settings.

• "no 90 degree turns".
• industry newgrfs.
• dealing with newgrfs that are financially challenging. Low loans, increased building costs, ect.
• non-trains. (Though some limited bus capability might be forthcoming).
• Support for versions other than the current stable release. (0.7.2 at this time)

Zuu wrote:I don't know if there is a recommended way. But I have 7Zip installed with the hooks for the right-click menu enabled. So I just right click on my AI's folder and go into the 7Zip menu and select "add to archive ..." and then in the dialog I select tar-archive if it is not what I last used.

There are certainly many other ways out there. Good to know is that 7Zip is an open source software and that it is hosted at sf.net. A quick google should get you to their homepage.

Zuu wrote:I think the most common error with tars would be that people make a tar of the contents of their AI directory without including the folder itself. OpenTTD requires that the folder is included in the tar, and not just having all the files directly in the tar.

Zutty wrote:Hey interesting AI Dustin. Its quite fun to watch it do its thing.

Zutty wrote:
I noticed a couple of small issues. First the TAR doesn't have a directory in it so it makes it harder to install. Second the "display signs" setting cant be turned off. In info.nut it says....

Code: Select all

AddSetting({name = "display_thinking", 
description = "Display signs showing what the pathfinder is thinking", 
easy_value = 1, medium_value = 1, hard_value = 1, custom_value = 1, flags = 0, min_value = 1, max_value = 1});

I think it should have min_value = 0, or you could change it to a boolean so it has a toggle button.

DustinAI v6 don't build any route
BuildRoute() (main.nut line 200) returns false while trying only one route.

Why kind of troubles exactly are you experiencing when uploading these little files to the Forum? Why do you think it comes to this? I'm really curious now that you've metioned it at least two times.

Zutty wrote:WOW! This is a huge improvement. It just barely turns a profit, but it can stay alive for 20+ years, unike the last version. It builds really fast, and I like the simple RoRo stations.

I noted though that the pathfinder is perhaps a bit to eager to build bridges, as you can see in the attached screenshot.

Still, keep up the good work

I did that to get the settings to take effect so I could see the debug signs. For some reason I can see and set the settings, but the ones I pick aren't used. Whatever is defined in the Info.nut is what is used. Any hints on how to fix my settings would be appreciated.
