ADRIFT for Mac

I see that there’s a new ADRIFT game nominated for the XYZZY “Best Game” category, Skybreak!

What’s the current state of ADRIFT for macOS? I see that there’s a very new version of ADRIFT 5 out, like, released literally last week, including an update of the Mono version of ADRIFT, but last time I tried it, the Mono version was completely broken, even on Linux.

Does the Mono version work at all, on any platform? Does it work on macOS? Could it be fixed?

The online ADRIFT runner is down, right? (Is it ever running? It was down when I last investigated ADRIFT in 2018 and as far as I’m aware it hasn’t worked in years.)


The online Runner has been working since IFComp 2019, except from some initial problems, but I understand why you ask.

It seems likely that the Mono-version still does not work on Mac, since (at least in the past) the Developer of ADRIFT was not able to test the Mac-version. I will ask him anyway - perhaps he has tested on Linux, which would increase the chance that the Mono-version also works on Mac. I will post here when I know more.

I just spent some time updating my Mono installation and installing the new ADRIFT runner (with the Sept. 9 release date) under Linux, and the package itself seems to be broken. Trying to run /usr/local/bin/adrift crashes, complaining that it can’t find /usr/local/lib/adrift5/MonoRunner.exe. This file is listed in the package contents in the README file, but doesn’t seem to be included in the archive itself.

Interesting. I tried it several times for Skybreak and it just sat there spinning for a minute plus and I gave up, but then I tried it just now and it just worked!


Thanks for reporting this. I will pass this on to the developer. Hopefully, he will upload a fixed version soon.

I haven’t tried anything like that. Perhaps your location matters(? - I am seated in Europe) or how many are playing simultaneously.

Hope you will have a problem free session of Skybreak! :slight_smile:

You were right, the MonoRunner.exe was missing previously, and that may also have been the case last year(?).

Anyway, the Mono-version has been updated on the download-page (you might have to refresh the page before downloading, so you don’t download an earlier version), so now it contains MonoRunner.exe. Hope you can get it to work on Linux. If you do, please let us know. If so, there is a chance it will work on Mac too.

I spent some time with the Mono build today, and I failed to get it to work. I claim that the Mono build doesn’t work at all on any game, though I’d be happy to be proven wrong.

I downloaded which includes a /usr/local directory. I copied its ./usr/local/bin/adrift script into /usr/local/bin and its ./usr/local/lib/adrift5 directory into /usr/local/lib.

On Ubuntu 20.04, I at first ran mono and Ubuntu prompted me to sudo apt install mono-runtime. This was a trap. When I tried running adrift after that, it printed on the Terminal: System.IO.FileNotFoundException: Could not load file or assembly 'WindowsBase, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

Googling, I found that the problem was that mono-runtime doesn’t include WindowsBase, and so I really needed to sudo apt install mono-complete.

Once I did that and reran adrift, it just spit out a couple of error dialogs.

Could not load type of field 'ADRIFT.My.MyProject:m_ComputerObjectProvider' (0) due to: Could not load file or assembly 'Microsoft.VisualBasic, Version=, Culture=neutral, PublicKeyToken=b03f5f711d50a3a' or one of its dependencies.

More Googling indicated that despite the name mono-complete, it doesn’t include Visual Basic, forcing me to sudo apt install mono-vbnc. When I did that and re-ran adrift, it popped up this error dialog exactly 34 times.

SaveSetting error: Invalid path

Despite those 34 errors, it did in fact launch!

Then I tried opening skybreak 1.2.taf and it printed another error.

The game didn’t start. Just in case this was somehow specific to Skybreak! I also tried Six Silver Bullets, and got a different error:

I didn’t get nearly this far when running Mono on macOS Catalina 10.15.6. I ran brew cask install mono-mdk, installed adrift in /usr/local/bin and adrift5 in /usr/local/lib, but when I launch adrift it crashes, presumably because Windows.Forms isn’t available in mono on 64-bit Catalina (Catalina provides only 64-bit libraries, with no 32-bit backward-compatibility support).

Thanks for the detailed information. I have passed this on to the ADRIFT Forum. Hopefully, the developer Campbell Wild will remove the Mono-version until it has been fixed.
