Great to see this.  Starman hasn't been active in quite some time, but magic was active last year.  And let me see if there are any others familiar with MechCommander who might be able to help.

MechCommander OmniTech / Patrol/Movement brain not responding to fire, any elegant solution?

« Last post by Hambourgeois on November 30, 2025, 01:51:12 pm »

Hello potentially dead forum,

I am having an issue with a mission I am working on. I have a mission brain set up to change the warrior brain of a bunch of mechs and vehicles to a patrol brain to move toward a base when you either (a) capture the base HQ or (b) approach the starting point of the relevant vehicles (will probably also add (c) when the base defenders are all destroyed). The movement part is working for both conditions currently implemented, however, when you attack this force en route to the base it does not respond to fire and does not return fire.

Unless I figure out a more elegant solution, I will probably just set them to have an escort brain targeting a Mobile HQ or similar, non-combat vehicle, have a wide scan range to ensure they are ahead of it if the player mechs approach, and just set the movement brain to the Mobile HQ (or whatever).

I have tried the original approach with both a basic patrol brain derived from the original MC2 warrior brains, and one using the universal warrior brain and both have the same problem. Not really a strong coder so if anyone knows of a more elegant solution in .abl I am all ears, otherwise just gonna move ahead with this.

FWIW here is the patrol brain from my most recent attempt:

The Scroll of Atankharzim / Re: RELEASE: The Scroll of Atankharzim, Part I

« Last post by Goober5000 on November 29, 2025, 05:40:41 pm »

Version 1.14.0 has been updated to Knossos with the following changes:

• Update the subtitle, jump computer, movie player, markbox, and weapon hit scripts with some refinements and some new features for Part 2
• Additional minor script fixes
• Always beam-protect the player's wing in The 4th Vial, not just when out of range
• Guardian the Irkalla's beams in The Tablet of Destinies until its shields are down
• Fix hotspot coordinates in the Vasudan main hall (a retail bug!)
• Refine table organization and improve MediaVP compatibility for duplicate ships
• Fix whiteout effect in Scroll intro on newer builds

Change log: (chronologically ordered)
PLACEHOLDER

Deprecations:
PLACEHOLDER

Deprecations are a mechanism in FSO where a certain feature or aspect of the engine has changed or is no longer supported. Since this would normally break existing mods, we have the mod table feature "$Target Version:" with which a mod can specify what version of FSO it was developed with. Any features listed under Deprecations will be removed or changed when the target version of a mod is at least the version released in this post.

Previous 23.2.1 Release Thread

Launchers, if you don't have one already:
All platforms: For every day use, we recommend Knossos.NET, an integrated solution for downloading and launching mods.

Hidden Text: Alternative Launchers • Show

Cross-platform: wxLauncher 0.12.x Test Build (legacy project for a unified launcher)
Important: For best compatibility with FSO 3.8 and later you should use at least wxLauncher 0.12.

Windows:  Launcher 5.5g (Mirror) (Mirror) Not compatible with Windows 8+, use wxLauncher above
OS X:  Soulstorm's OS X Launcher 3.0
Linux:  YAL or by hand or whatever you can figure out.

This one is based on the AVX Optimizations from the MSVC Compiler.

What are those SSE, SSE2 and AVX builds I keep seeing everywhere?
Your answer is in this topic.
Don't want to deal with that? Use Knossos.NET and it will download the best build specifically for your PC!

Linux
Compiled with Ubuntu 20.04 LTS, GCC 9
x86_64: fs2_open_25_0_0-RC5-builds-Linux-x86_64.tar.gz
arm64: fs2_open_25_0_0-RC5-builds-Linux-arm64.tar.gz

These builds use a mechanism called AppImage which should allow these builds to run on most Linux distributions. However, we recommend that you compile your own builds which will result in less issues.
Alternatively, if there is a package in your software repository then you should use that. If you are the maintainer of such a package for a distribution then let us know and we will include that here.


macOS
macOS 10.9+
Intel (64-bit): fs2_open_25_0_0-RC5-builds-Mac-x86_64.tar.gz
Apple Silicon: fs2_open_25_0_0-RC5-builds-Mac-arm64.tar.gz

These builds are not signed and so by default will fail to launch. To run them simply right-click on the app, click open, then click open again on the security confirmation dialog. You should only have to do this once for each app.
If running the game through Knossos or Knossos.NET this step should not be necessary.

NOTE: macOS builds currently have limited support and may exhibit issues not present on other platforms.

FreeSpace Conversion / Re: RELEASE: Official Awakenings for Port 3.0

« Last post by Goober5000 on November 29, 2025, 01:52:01 am »

I see what the problem is.  The Galatea 1's waypoint path takes it straight through the hull of the Orion.  This must not have been a problem with the earlier model designs.  I've uploaded a fix.

FreeSpace Discussion / Re: Transferring data to new computer

« Last post by Mongoose on November 28, 2025, 11:59:33 am »

As you said in the other thread, the .csg files in your players folder should save your campaign progress, including medals and kill lists. (The wiki says these files have been deprecated and replaced with .cs2, but I'm not sure how new of an FSO version does that; whatever version I have installed still makes .csg files for a new pilot.) You'll also want to back up your main pilot file with the extension .json. If you've changed any control presets, I think those may live in the presets subfolder, so probably best to back that up too. (I don't know if those are a duplicate of what's in your pilot file or their own thing entirely.)

Going to close this, since you already asked the same question in another thread. I'll respond there. Please try to keep topics in a single thread.

Then probably some other dependency is missing. Probably fonts from SCP UI or something else. Once again: I strongly advice to try installing it with Knossos.
