Hosting a bot from Ubuntu server?

Michael Hoover

I've looked around and can't seem to find any helpful tips on hosting a bot from a headless linux server (specifically ubuntu 18.04). Is it possible? If I missed the topic please point me to the right location. Thanks!

@Michael-Hoover Are you attempting to do it live in the lobby?

Michael Hoover

Yeah I would like to if I can.

@Michael-Hoover hmm we might need to dig but here is a link for the current Linux pre release
https://github.com/triplea-game/triplea/releases/download/2.0.18542/TripleA_2.0.18542_unix.sh
https://github.com/triplea-game/triplea/releases/download/2.0.18542/triplea-game-headless-2.0.18542.zip
sadly as a win 10 user I am not sure if that is much help

Michael Hoover

Thanks I'll check it out.

@Michael-Hoover in the triplea-game-headless link prastle posted, if you unzip the file you should notice there is a 'run_bot' linux executable. Edit the script with the right parameters as needed, then if you run it, should work.

Michael Hoover

Excellent! Thanks again I'll start messing around with this today.

Michael Hoover

Well, I thought I had everything set up correctly, alas here be the errors I am currently getting after running the script:

OK I got the test to work by rolling back to version 1.9.0.0.12226
Is this OK?

In the meanwhile I am going to tidy up a bit and see about automating the bot on reboot...

Michael Hoover

OK so the only two things I can't seem to figure out:

When I start the bot the "Name" field in the lobby is always blank. Not sure how to default this value?
Not sure how to allocate AI to open positions (this may not be a thing please let me know if you can)?

LaFayette

1.9.0.0.12226 is a good version for bots. There is something we messed up in 13066.
The name field should be coming from one of the parameters in the run_bot script. It's interesting you can join and have a blank name. Let us know if you cannot find it.
Adding AIs to bot games is currently not possible

Michael Hoover

Thanks for all the help everyone. I have four bots up on an Ubuntu server now. 3 are public, one is passworded for my personal use. Let me know if anything is funky. I know I don't have all the maps downloaded yet but I want to let them run for a bit for QC/testing.

I realize you guys probably don't need the extra bots, but this has become an academic exercise for me at this point

prastle

@Michael-Hoover Play tested briefly a bit of a round. WELL DONE SIR!

LaFayette

FWIW @Michael-Hoover , this is the script we use to download all maps: https://github.com/triplea-game/triplea/blob/master/infrastructure/ansible/roles/bot/templates/download-all-maps.j2

The stuff in {{ }} are template variables, you'll want to remove/update those as necessary.
