Robocode Tank Royale on macOS 12.3.1 (x64/ARM) no bot can join and error with .NET6

[CodeMonkeyBoy]

Hey,

first I want to thank you for Robocode, I like your work very much. Keep up the awesome work!

I played the "old" version a lot and saw there is a new version which I want to give it a try.
But sadly I cant't get it to work on both of my machines running macOS 12.3.1

First, it is not compatible with .NET6 LTS SDK (.NET5 will EoL May 10th 2022) they changed something in the System.Globalization so the Demo bots throw System.Globalization.CultureNotFoundException: Culture is not supported. (Parameter 'culture') 4096 (0x1000) is an invalid culture identifier. so it is unplayable on Apple Silicon chips because .NET5 doesn't really support these chips.
To avoid this Exception you can clear the value of countryCodes from the *.json in the bot folder.

Secondly it will still not work, the GUI starts, Server is up and running, but none of the bots can connect.
Bootup in the GUI seem to work but none can join, nothing shows up.

In the Terminal I tested it with the C# bots and get Connected to ws://localhost:7654/ Disconnected from ws://localhost:7654/, status code: 1008, reason: Wrong secret on both Machines (x64 and ARM).
So I startup the Java bots with the *.sh, same error message...wrong secret. The server writes some secret into the properties, copy that into the json as "secret" still doesn't work.

Did I miss something?
How should i configure the server to allow any bot? The GUI can connect and test the server.

Thanks in advance and best regards
Ben

Hi @CodeMonkeyBoy

Upgrading to .Net 6 seems like a good idea, so I will look into that.

You are right that you need the secret from the server.properties (from bots-secret field).
Read more info here

The secret is not meant to be set in the bot's metadata (JSON) file, but instead as environment variable:

export SERVER_SECRET=s0m3R0bOc0dEs3crEt

I hope setting the SERVER_SECRET will work for you?

Awesome work and thanks for the Update to .NET6, I don't know how i missed that part with the Server Secret, but honestly I didn't look into the Debugging Section.
With export SERVER_SECRET it worked like a charm.

I saw it in the Schema of the JSON, so i thought it would go there. Nevertheless so it worked.

@CodeMonkeyBoy

I have now upgraded the Bot API for .Net to use .Net 6 with release 0.13.0

[flemming-n-larsen]

I will try this out on macOS and Linux. Don't worry. 🙂

[flemming-n-larsen]

I am able to reproduce the issue on macOS. But it seems to be a tricky/nasty issue to fix. So I will look deeper into solving this.

I found the bug, which was with running a process using bash with the -c (command) option, that needed quote marks when white spaces are being used. The fix will be available with the next release. 🙂

@CodeMonkeyBoy
The fix for whitespaces is now available with release 0.13.3 😊
