I'm working on some code to run a tournament of AIs, and as part of that I'd like to have a gamescript that does some logging. I'm trying to run the gamescript against a dedicated server.

I've got AIs working, and that's fine. But I've got a dead-simple Gamescript, and it's failing silently and I can't figure out why.

Here's the info.nut:

Code: Select all

class Arbiter extends GSInfo {
  function GetAuthor()      { return "gregdek"; }
  function GetName()        { return "Arbiter"; }
  function GetDescription() { return "An arbiter of AI-only games"; }
  function GetVersion()     { return 1; }
  function GetDate()        { return "2021-02-02"; }
  function CreateInstance() { return "Arbiter"; }
  function GetShortName()   { return "ARBX"; }
  function GetAPIVersion()  { return "1.9"; }
  function GetSettings();
}

/* Tell the core we are a GS */
RegisterGS(Arbiter());

And here's the main.nut:

Code: Select all

class Arbiter extends GSController 
{
    constructor()
}

function Arbiter::Start()
{
  GSLog.Info("[arbi] I am here!");
  GSController.Sleep(1);
  while (true) {
    // we just wait every 10 ticks and ping
    GSLog.Info("[arbi] I am still here!");
    GSController.Sleep(10);
  }
}

And here's how I'm invoking it in openttd.cfg:

Code: Select all

[game_scripts]
arbiter = foo=1

And nothing. I've got debug logs turned up to 9 across the board, and I know that OpenTTD finds the tar file and the .nut files, but then it's just silent failure.

Any hints? I'm tearing my hair out. Thanks!

You are missing semi collon after the constructor, the well known hair tearer

Sadly, that is not the problem. I added the semicolon, no luck.

I mean, I'm sure it's something dumb like that -- maybe I'm not invoking it properly in the config file -- but there's no hints anywhere in the logs at all, nothing, even with -d 9. I know the dedicated server sees the tarball

Code: Select all

dbg: [misc] Found dir in tar: arbiter/
dbg: [misc] Found file in tar: arbiter/info.nut (524 bytes, 3072 offset)
dbg: [misc] Found file in tar: arbiter/main.nut (286 bytes, 5632 offset)
dbg: [misc] Found tar '/home/openttd/content_download/game/arbiter.tar' with 2 new files

...but then: nothing.

The semicolon was a problem, without it, it was crashing.

Tested it in a dedicated server with a visible element, pauses, and it was working well.

Code: Select all

class Arbiter extends GSController 
{
    constructor();
}

function Arbiter::Start()
{
  GSLog.Info("[arbi] I am here!");
  GSController.Sleep(10);

  while (true) {
    // we just wait every 10 ticks and ping
    GSLog.Info("[arbi] I am still here!");
    GSController.Sleep(100);
    GSGame.Pause();
    GSController.Sleep(100);
    GSGame.Unpause();
  }
}

Code: Select all
