Operation Sunset: The Battle for Badme (1999)

[Correcaminos]

Damn, in the end it was much simpler than I thought... but better that way.
​Apologies for missing the obvious . I was overcomplicating things...Thanks for pointing it out.

[Kushan04]

Was it that?

It is always a good idea when requesting lua code for CMO to an AI, to add:

But use only working lua code from this site

https://commandlua.github.io/

Even doing that, you still need to check it. In my experience, even if I tell it to use function X, it'll still do stupid shit. ChatGPT in particular loves to put the scen edit add unit function inside a custom add unit function that does the same thing. It's better then it used to be but it still requires a sanity check of everything it spits out.

[Correcaminos]

It is clear that manual review is more than necessary. I actually tried testing via the console, but evidently not thoroughly enough to catch that specific crash.
​I ll try avoiding Lua when possible, too. Sometimes we overcomplicate our lives with scripts when native triggers might work just fine.
​Thanks for the help, guys.

[Nikel]

I have tested just a few times and have no knowledge of lua.

Tried with Chatgpt, Grok and Perplexity, the last one seems the less prone to inventions, always giving them the link posted above.

But without knowledge I only could try running this code in the lua console, copy the errors to the AI and repeat.

[Correcaminos]

Just completed a full verification run on v1.37.

Happy to say that everything is working correctly and as I wished . The logic holds up, the triggers fire correctly upon reaching 700 points + Ship Kill, and the session ends smoothly with no stability issues



Mission accomplished. Thanks to everyone who helped polish the final details

v1.37 tested.


This time could not see the victory screen.

Those nasty MiGs nearly destroyed all my Flankers

Still is considered a major victory with 505 points.


The Grads destroyed one of the hunters-killers, one unit per site should be enough.

Land detachment near Bahir-Dar, still there.

And I still see this.

It was the Cargo drop lua! Modified, it wasn't working for me because I had to enter the area at a different height

-- D. CLOSE EVENT

ScenEdit_SetEvent(eventName, {isActive=false})

print("LOG: Launch completed."

Scoring Fixed I completely forgot to check this earlier, sorry







Removed most of the Grads. I left just one unit per site, which should be enough

Regarding the units near Bahir-Dar, I decided not to move them. As I mentioned, they are part of the Air Drop sequence and they don't interfere with the mission (they are not meant for hunting SA-9s). I could have hidden them or used a neutral side to avoid confusion, but I didn't want to overcomplicate the mission setup any further for now

V1.38

[Nikel]

Yes, I had a save just before the dropping and the lua history file with the errors is created when the first drop happens.

It is printed 2 times because there are 2 drops.

But it has no consequences, has it? The points are assigned and the teleporting of units is done.

The error is printed in the lua history file because of this line, as was indicated by kushan and blu3s.

ScenEdit_SetEventState(nombreEvento, 'InActive')

It is not related with the altitude, or perhaps I am not understanding what you mean

[Nikel]

v1.38 Tested

Triumph with 705 points



This time the Air combat was completely different, and the Flankers destroyed 5 MiGs with 0 losses.

The drop event now appears only one time in the scoring log.

What appears more than one time is the victory message, if you continue the scenario.

I continued because in that moment I was still destroying all the Eritrean Forces with the Hinds, and the victory message appeared 2 more times. I think should only appear 1 time.

NLua errors gone. The only text that is printed now in the lua history file is this:

LOG: Lanzamiento finalizado.

Perhaps you are happy with this results or want to mess more with this scenario?

The only suggestion I have, is perhaps to make the sinking of the cargo ship more difficult, the Osa II guns are not really very effective in air defense. MiGs CAP?

If the cargo is so important should be better defended.

[Correcaminos]

As is often the case, the simplest solution for the Cargo Lua error was the right one. I still want to test one variation of that script for future missions, but for now, it works perfectly.
​Regarding the Victory Message loop: That is an easy fix. I just need to add the 'famous' script of this long thread (SetEvent... isActive=false) at the very end. That way, once the victory check is passed, the event shuts down and won't bother the player again if they choose to 'Continue'.
​Regarding the Ship: We could definitely ramp it up (random spawn points, heavy traffic, a MiG-21 CAP...), but I think I'll leave it as is. Historically, Eritrea had limited assets in that sector, and the premise is that Intelligence did their job locating the MV Dahlak. I like the current balance.
​I think I'm ready to wrap this one up. I'm eager to start a new project in the Barents Sea—something purely Naval—where I plan to test loading Briefing images directly from local folders.
​One last thing: I will be adding you to the scenario credits for the v1.39 final release. Your help with testing has been invaluable, as always

[Nikel]

Great, thanks.
