Quote from: {AR}MetalKiller on February 18, 2026, 07:09:01 AMHow exactly have you set up your project?
Do you add the new unit class to the all.req file and copy the munged all.lvl file over to the GameData/Data/lvl_pc/Sides/ folder?
Or did you munge the tat2 map and use it from the addon folder?

Yes,I have added the unit to the all.req file and created the file inside the "REQ" folder. Inside the ODF folder I've created the unit itself. After munging I have copied the file ALL.LVL into the "GameData/Data/lvl_pc/Sides/" folder. With this technique I've already created a new unit replacing the darktrooper and modified other ODF values, this works perfectly fine. (and has been a ton of fun)

I did not munge TAT2 into my addon folder.


To give some more context about my process: I run game version 1.3.7 GOG, I have created the mod using BFbuilder pro and us it to munge the SIDE LVLs. The mission.LVL I made using battlebektoolbox.

Quote from: {AR}MetalKiller on February 18, 2026, 07:09:01 AMRegarding your changes to the soldier class: It would be helpful to see what lines you changed in the odf.

These are the only lines I changed and causes the crashes once NPCs spawn. Once I undo these changes the game runs fine again. I've tested this 5+ times.
The oddd thing is that if for example I use the same method to remove the mines from the vanguard, there are no issues whatsoever.

WeaponName1         = "all_weap_inf_rifle"
WeaponAmmo1         = 6
WeaponName2         = "all_weap_inf_pistol"
WeaponAmmo2         = 0
WeaponName3         = "all_weap_inf_thermaldetonator"
WeaponAmmo3         = 3
WeaponChannel3        = 1
//WeaponName4         = "all_weap_inf_crackgrenade"
//WeaponAmmo4         = 3
//WeaponChannel4    = 1

I am starting to think that some AI routine is looking at the loadouts of several classes (rebel soldier, smuggler) and once some classes are changed, they're no longer compatible with the AI routine.

Sorry, should have been more specific.
Your first guess is right.
However, that should not be the problem since you were able to replace the marksman with the new unit.
I initially misread your first post.

ReadDataFile("dc:SIDE\\all.lvl"

How exactly have you set up your project?
Do you add the new unit class to the all.req file and copy the munged all.lvl file over to the GameData/Data/lvl_pc/Sides/ folder?
Or did you munge the tat2 map and use it from the addon folder?



Regarding your changes to the soldier class: It would be helpful to see what lines you changed in the odf.

Ah I see, could you give an example of what the syntax would look like? Or an existing forum thread that goes into more detail? Because I tried several things like:

ReadDataFile("DC:SIDE\\all.lvl"

ReadDataFile("dc\\SIDE\\all.lvl"

ReadDataFile("dc\SIDE\\all.lvl"

And all of them resulted in crashes.

You need a "dc" infront of your SIDE\\all.lvl.
The ReadDataFile function specifies a filepath.
If no dc is put infront the default all.lvl is loaded. Because the default lvl does not know about the flanker it crashes.

Since my first message I did some experimentation and found that replacing the darktrooper class posed no problems. The game kept running and the NPCs played the new class without issue. So I am puzzled as to why editing the smuggler and rebel trooper classes (or their loadout) causes issues.

Just before writing this reply I tested it again just to be sure. It crashes as soon as the NPCs join, but in an PVP LAN match the class is fully playable without issue.

Thanks again for taking the time

Video of gameplay including the expanded droid hall area

your welcome do post some screenshots of your work

Go ahead and share your mission.lvl lua changes here, and we'll see what we can figure out with them.

Amazing, working perfectly, thank you so much!

Over four years later, I have returned to work on this, looking to make some improvements to the layout and models:

-I'm aiming to add emissive to many of the 'lights' in the level. They won't be true lights since SWBF1 does not have glow, but it should look better
-I've made the droid hall much wider, you no longer can get trapped behind the stairs
-I've built new ramp modules to add some extra verticality and tweaked existing corridor modules so they can fit together more cleanly
-I've added an option to play with stock sides

Work is still ongoing so no ETA yet, this one's a bit more complicated than the Battle of Hoth tweaks (which are pretty much done at this point, expect a release in the near future of that)
