Discuss the new AI features ("NoAI") introduced into OpenTTD 0.7, allowing you to implement custom AIs, and the new Game Scripts available in OpenTTD 1.2 and higher.

Because it doesn't answer you questions, it's only a complement for the curious people. The important part of the message is in normal size.

Some AI cause errors in my game and I wish to replace it (in loaded game) by other AI - how can I do that ?
I didn't find any command for console to replace AI and change AI settings don't help.
* Save your game
* Remove all compatible versions of the used AI (easiest if you don't know which ones that are compatible is to remove all versions of AIs with the same name). You need to remove the tar files or directories with .nut files of the AI from the search paths of OpenTTD (see the Readme for all search paths).
* Restart OpenTTD (not sure if it is needed, but doesn't hurt. Doing this you can verify that the AI has actually been removed in the AI Settings dialog)
* Load your save game
Now the game should pick a random AI.
Note again that I haven't tried this myself and I don't know if this actually works. It was the proposal that I think got implemented but I haven't checked myself.
Edit: We are of course interested to hear from you which AI is it that you have problem with?
My OpenTTD contributions (AIs, Game Scripts, patches, OpenTTD Auto Updater, and some sprites) Junctioneer (a traffic intersection simulator)

Thanks for advices - I'll try it (hopefully I use only 1 newest version of each AI).
Choochoo caused some errors (I send pm with screenshot to author already).
Some AIs didn't started yet but present AIs in game are: AdmiralAI.22 and CluelessPlus-v15 (AdmiralAI going to bankrupt again - probably due to Modified Building Costs grf and hard difficulty).
BTW *.gz files are read in the same way like *.tar by the game ?
If I do a minor change (small fix, optimisation, etc.) that doesn't break save/load version and does not change OTTD API version nor libraries dependencies, do I need to increment the version of my script?
Or bananas will check upload date and propose to upgrade regardless the version?

I could not find this information as well, so I tried it. I tried to use subversion for a fix release and it worked fine. I did not change the gamescript version, but I increased the version in BaNaNaS and it is proposing the newer version correctly. But I don't know if it was chosen by version or date.

Update: This statement in the GS API documentation is exactly correct (checked the source code as well): When OpenTTD finds, during starting, a duplicate GS with the same version number one is randomly chosen. So it is important that this number is regularly updated/incremented.
Which means what I said was incorrect and the version in Info.nut (GSInfo) must be incremented with each new release. If you want to make savegame compatible update, you should increment the version and keep the MinVersionToLoad from the previous release.
