Derick

FWIW, I tried again and now it all works lovely — No idea why :-)

Yes, the ZIP files as download through the links provided through GitHub and from Sarbian: https://github.com/jrodrigv/PhysicsRangeExtender/releases/download/1.19.0/PhysicsRangeExtender.1.19_03282020.zip https://github.com/PapaJoesSoup/BDArmory/releases/download/v1.3.4/BDArmory.1.3.4.0_04092020.zip https://ksp.sarbian.com/jenkins/job/ModuleManager/157/artifact/ModuleManager-4.1.3.zip Yes, it's in the correct Gamedata folder: derick@singlemalt:~/games/kerbal/BD-KSP/KSP_linux$ ls -l GameData/ total 2420 drwxr-xr-x 16 derick derick 4096 May 10 14:43 BDArmory -rw-r--r-- 1 derick derick 141824 Nov 30 14:55 ModuleManager.4.1.3.dll -rw-r--r-- 1 derick derick 2186618 May 10 15:25 ModuleManager.ConfigCache -rw-r--r-- 1 derick derick 93204 May 10 15:25 ModuleManager.ConfigSHA -rw-r--r-- 1 derick derick 8662 May 10 15:25 ModuleManager.Physics -rw-r--r-- 1 derick derick 27686 May 10 15:25 ModuleManager.TechTree drwxr-xr-x 4 derick derick 4096 May 10 14:20 PhysicsRangeExtender drwx------ 21 derick derick 4096 May 10 14:25 Squad derick@singlemalt:~/games/kerbal/BD-KSP/KSP_linux$ ls -l GameData/*/settings.cfg -rw-r--r-- 1 derick derick 2741 May 10 15:33 GameData/BDArmory/settings.cfg -rw-r--r-- 1 derick derick 116 Apr 22 2019 GameData/PhysicsRangeExtender/settings.cfg The GAU-8s are set to target everything (including Air). I can manually fire them, as long as I set "infinite Ammo". I think the crux of the problem is that it doesn't see there there *is* ammo, even though I've added the boxes to the craft.

I've just made a new install of KSP 1.9.1, BDArmory.1.3.4.0_04092020.zip, ModuleManager-4.1.3.zip, and PhysicsRangeExtender.1.19_03282020.zip. Created a new craft, and added two GAU guns, 30mm ammo, Flight AI and Weapon Manager parts to it. It starts up fine, with two of these crafts doing their usual dog fight manoeuvrers, however, they never fire their weapons because I see "Ammo Left: 0". I first thought I had added the wrong type of ammo, but it's right. I do get things to fire when I set "Infinite Ammo", but that doesn't seem to do anything in Competition Mode (I guess the AI reads whether there is ammo left before attempting to fire?). Looked at the log but couldn't see anything out of the ordinary. Help? :-)
