JAS 39C Gripen Community Mod

[VR Flight Guy in PJ Pants]

Almost all of above.

On sale!

[Archangel44]

Yes it is.

Pay day this Friday, hopefully they won’t sell out.

Did the Gripen mod/carrier disappearing problem ever get fixed?

[sebfoo]

Unfortunately the mod no longer works with the recent update 2.9.6.57650 (11 July). When a mission with the gripen is started, the game crashes.

[flavnet]

The same for me

[TKhaos]

I think it's to do with the Flaming Cliffs 3 cockpits and not so much the game update. All my mods where still working after the update, once I updated to FC 2024 practically all VSN mods stopped working immediately, or at least the ones that use the F-15C cockpit in some way, the ones that use the A-10A and SU-25T based cockpits still work.

I did have issues with the Gripen a while back as well, if I installed it all my aircraft carriers disappeared. I removed all my mods and added back one at a time and that was the mod that broke the carriers. Have to retry once the current problem is sorted as I used to enjoy flying it but I do a lot of carrier based stuff so helps if I got something to land on

Gripen also broke the Supercarrier for me prior to the latest update. I did a test with no other mods installed and it still broke there is some specific Gripen-Supercarrier conflict (pre-2.9.6).

Yeah mine was all pre update, was last year I noticed it. I did a mission and was supposed to launch with a Harrier off the carrier and it wasn't there so just dropped into the sea, then tried it with the F/A-18 and did the same and there was no carriers anywhere to be seen in any of my missions. I never really noticed before because most of my stuff was land based then I got the F/A-18 followed by Supercarrier as I thought that would fix it

[Smerkz]

I just installed the mod and there is no input from my hotas or throttle, only keyboard. Is there are quick way to activate hotas for the mod?

Hey guys!
Is the Gripen mod still maintained? Doesn't seem so ...

last update was march of last year, probably RL got in the way of the developers. I truly enjoyed this Mod for a long while but have to admit that I’ve moved on to other aircraft as DCS offers so many interesting aircraft to learn. Even so, I’m grateful to @whisky.actual for maintaining this Mod for so long.

[TOViper]

Understandable.

Hi, you have to put the JAS39C folder in the path C:\Users\username\Saved Games\DCS\Mods\aircraft. You probably put it in the main directory of the game, that's why you get this message.

even if i do this i still have crash not only with this mod but also with SU-25T id on't know what to do

Can someone please help me, unfortunately all of my anti-radar missiles explode shortly after takeoff, why is that?

It seems there was never a solution where the JAS-39C mod prevented the spawning of carriers since 2023. I liked to do a lot of carrier operations so I uninstalled it. 

I just reinstalled it and verified the problem still exists with the latest version of DCS so I checked the "%USERPROFILE%\Saved Games\DCS\dcs.log" which provided a hint to the cause of the issue:

2024-10-05 00:35:25.578 INFO    APP (Main): MissionSpawn:spawnShips 2
2024-10-05 00:35:25.616 ERROR   woShip (Main): Failed to create ship: Descriptor not found weapons.shells.M61_20_HE_gr
2024-10-05 00:35:25.638 ERROR   woShip (Main): Failed to create ship: Descriptor not found weapons.shells.M2_12_7_T
2024-10-05 00:35:25.701 WARNING LOG (29364): 2 duplicate message(s) skipped.

It seems the JAS-39C mod has too much variety of weapons where DCS has either only allocated a fixed amount of memory or a fixed number of array slots for them. It does not seem to be an out of physical memory.

If you view the file "%USERPROFILE%\Saved Games\DCS\Mods\aircraft\JAS39\Weapons\Loadout.lua" you will see a lot of lines starting with "dofile":

e.g.

dofile(current_mod_path .. '/Weapons/Loadouts/jas39_m71ld.lua')
dofile(current_mod_path .. '/Weapons/Loadouts/jas39_m71hd.lua'))

...

dofile(current_mod_path .. '/Weapons/Loadouts/jas39_agm-65h.lua')

There are too many of them preventing the carrier spawning. As a quick test I commented out approximately half of them. This allowed DCS to load the JAS-39C mod and also the F-14/F-18 instant action missions to spawn carriers.

You should be able to fly the Gripen with carriers by commenting out the weapons you don't need. Precede "dofile" with two minus symbols (e.g. -- ) to comment out a line.

e.g.

 -- dofile(current_mod_path .. '/Weapons/Loadouts/jas39_m71ld.lua')

 

Since the removal of FC3 and introduction of FC2024, you will also need to the workaround described by this thread.

Hi, almost mods with specific weapons makes carriers dissapear. The quick alternative is to make those weapons.lua to dissapear or abstract by adding the -- in front of the entry or the plane where the weapon lua is mentionned. With this method you can find the weapon which makes problem.

If you want that weapon to work it will be only for the IA with minor modifications on the lua concerned.

In a process of elimination you can comment out the following 2 lines in "%USERPROFILE%\Saved Games\DCS\Mods\aircraft\JAS39\Weapons\Loadout.lua" so that carriers can spawn:

e.g.

-- dofile(current_mod_path .. '/Weapons/Loadouts/jas39_dws39_arm.lua')
-- dofile(current_mod_path .. '/Weapons/Loadouts/jas39_dws39_tv.lua')

it's not a memory limitation but an issue with jas39_dws39_arm.lua and jas39_dws39_tv.lua

Don't know if this helps but DWS 39 is a name for the gliding cluster bomb the real-life Gripen can carry.  I'm sure we can go without it please to get the rest of Gripen working, eh?

[Archangel44]

I hope the creator has time and is willing to spend time working on the mod.

I don’t like the JF -17 and only reason why I would purchase the the JF was to fly the Gripen based on the JF.

I like the Gripen based on the F-15C.

[cj43g3r]

Reviewing this entire thread, Urbi found the solution on 12/23/2023 for spawning carriers. See RaptorFighter's post on 12/23/2023

To make the solution more clear, modify the following files:

"%USERPROFILE%\Saved Games\DCS\Mods\aircraft\JAS39\Weapons\jas39_dws39_arm.lua" line 188 from

cluster = cluster_desc("Bomb_Other", wsType_Bomb_Cluster,

to

cluster = cluster_desc("Bomb_Other", wsType_Bomb_Cluster, levParam),

"%USERPROFILE%\Saved Games\DCS\Mods\aircraft\JAS39\Weapons\jas39_dws39_tv.lua" line 188 from

cluster = cluster_desc("Bomb_Other", wsType_Bomb_Cluster,

to

cluster = cluster_desc("Bomb_Other", wsType_Bomb_Cluster, levParam),

I’m hoping someone here can help me with this bird.

First, thank you to all who contributed in allowing us to use this bird.

After inputting the fixes, I can see the ships now.

I still have to start up in an F15C and then jump into the Gripen.

The issue I have is that when I jump into the Gripen, my FPS just drops to 10 or less and no fun flying like this.

Any help would be appreciated, please ask me questions if needed.

@Archangel44

Regarding the  F15C dependency, see 

 

I've created a tool to simplify this at https://www.digitalcombatsimulator.com/en/files/3340679/

It doesn't solve all issues related to upgrading to FC2024 but is a step in that direction.

 

Regarding the FPS, it is a hardware performance issue where the mod is attempting to render a "fisheye" view in the cockpit. See whiskey.actual's post on April 5, 2023.

If you're using VR, you can try head tracking vs VR to reduce performance hardware requirements.

You can also try reducing the game resolution, DCS visual quality under options/system (especially forest details factor/scenery details factor) to reduce the workload.

You can try disabling unnecessary windows services to remove resource usage and processor load.

I don't know if you've optimized your system. But enabling resizeable BAR in the UEFI/BIOS is a way of increasing GPU performance.

And reducing competing CPU resources by disabling CPU affinity for CPU0. e.g. Unselect CPU affinity for CPU0 for DCS, head tracking software (e.g. opentrack) so that they will run on other CPUs. CPU0 will have a lower load and more time to process interrupts since it seems many interrupts are just assigned to CPU0 by default. This seems to significantly reduce mission load times on my system
