I have a request: an option to spawn a mission (not UFO) right at the coordinates of X-Com base. This would be the same as normal spawning at a fixed point, except instead of given coordinates it would choose one of your bases (at random, if there's more than one).
Justification (in the context of Piratez as a good example):
- It would allow to remove "comm waves", which are a not-so-elegant hack.
- It would allow special missions taking place directly at your base, for example "attack of creatures from the sewers".
- It would allow creation of some missions which would logically take place around the base.
Optional considerations:
Terrain used would be governed by alienDeployments, same as with normal missions, but also including your base.
Also, it would be nice to have an option to tie the terrain to the global texture instead of specifying it directly, because (for missions not actually happening inside your base, but outside) the game doesn't know where the player will put their bases.
-
This could be useful.
-
what is the purpose of "comm waves" today?
-
Comm waves are a hack to spawn a base assault which cannot be prevented: it's a UFO which moves at light speed and therefore cannot be shot down. Basically it simulates a base assault which is not made by dropping the invading force from air, but in some other way: they come by land, or from the underground, or teleport in, whatever.
My request is partially a way to do it more cleanly, but this is not the most important part, more like an additional boon. The most important thing is to be able to create base assaults without UFOs and without X-Com base detection. It would also allow to make other missions which do not take place on the X-Com base, but still should be in the same place on the globe, like for example exploring the caves beneath your base in Piratez.
-
Maybe we can have syntax like that to solve the problem:
alienMissions:
- type: STR_ALIEN_RETALIATION
points: 0
objective: 4
spawnUfo: STR_BATTLESHIP # Vanilla - Spawned for the final retaliation run
baseDefenseCustomDeployment: STR_BATTLESHIP #case we still want base defense without any ufo
customMissionDeploument: STR_CULT_SAFEHOUSE #custom deployment, that would be spawned on top of the base
so before we to spawn a ufo with
const RuleUfo &battleshipRule = *mod.getUfo(_rule.getSpawnUfo(), true);
const UfoTrajectory &assaultTrajectory = *mod.getUfoTrajectory(UfoTrajectory::RETALIATION_ASSAULT_RUN, true);
Ufo *ufo = new Ufo(&battleshipRule, game.getId("STR_UFO_UNIQUE"));
ufo->setMissionInfo(this, &assaultTrajectory);
we can choose to spawn base defence with deployment `data:` loaded from `baseDefenseCustomDeployment:` or even just spawn a mission site within region's xcom base coordinates using `customMissionDeploument:`. I think we can process each rules suquencially using something like if(!ruleProperty.empty()), or pick only one with priorities customMissionDeploument -> baseDefenseCustomDeployment -> spawnUfo.
Also, I looked at how to tweak base defense deployment to make special one and end up to use the dirty hack, that is working more or less ok for FTA, but to make a general solution to use other properties other than `data` for baseDefenseCustomDeployment case it looks to me we should do a big job with battlsescape generation.

ok, I will ignore this part for now
1) The most important thing is to be able to create base assaults without UFOs and without X-Com base detection.
2) It would also allow to make other missions which do not take place on the X-Com base, but still should be in the same place on the globe, like for example exploring the caves beneath your base in Piratez.
But 1) and 2) are two completely different things... I don't see how they relate at all... or how could they be done by just a single feature?
Can you elaborate why you talk about them as one feature?
How would implementing 1) also implement 2) ?
-
The only difference as I see it is that one uses the X-Com base layout, and the other uses a terrain declared by the modder.
No idea if it makes sense from the coding perspective, but in my view it's the only functional difference.
-
I'm not sure if I understand this correctly, but to me these sound like two distinct features:
1)Directly Trigger base assault without UFOs
2)Create mission sites at player base location
The difference - as far as I can tell - is that mission sites can't trigger base assaults and by extension can't destroy player bases. Taking a stab in the dark here, but if I follow your train of thought (missions "at" the player base) aren't you also asking for a third feature - triggering base assaults (on the closest player base) on mission failure?
If the player is supposed to fight off a invasion via the base sewers, what happens when he fails/abandons the mission? Shouldn't this trigger a "real" base assault?
-
ok, so maybe let's start from the beginning

Doable.
Optional considerations:

I don't get this... what does "including your base" mean?
Should it be a base defense mission (with a real base map) or not? Does the battlescape map correspond to a real base... or is it something fake/random?
Also, it would be nice to have an option to tie the terrain to the global texture instead of specifying it directly, because (for missions not actually happening inside your base, but outside) the game doesn't know where the player will put their bases.
What do I need to do here?
Isn't this already possible with the 'globeTerrain' mapscript constant? https://openxcom.org/forum/index.php/topic,7536.0.html
-
Doable.
Bueno!

Yes!

Yes!

Not sure what you mean exactly, but what I want is two separate options:
1) Real base map, exactly like on a normal base defence. (For base defence not triggered by a UFO.)
2) Some other terrain, defined in the alienDeployments. (For missions which should logically happen around your base, like exploring the surroundings, but not in the actual base.)
(So yes, Krautbernd is correct.)

Perhaps, frankly I am not familiar with this option. I'll investigate.

I haven't planned anything this involved, a base defence is a base defence, doesn't matter from where.

OK.
Just that option 1) is directly in conflict with the name of this thread "Spawning missions at base coords"... as no mission site will be spawned at all.
That was the confusion.

All right, sorry for the confusion. Not sure if a base defence counts as a "mission" or not :)

Sorry for being pedantic, but it's not a base defence if failing the mission doen't result in the player losing the base - that's why I was trying to ascertain what it is you're asking for.
One of your examples was "player base is attacked via the sewers", so you want a mission site spawned at the base coordinates that takes place in an underground/sewer map. But how would this be different from a "standard" sewer mission site? What is the incentive here if the player can simply ignore the site alltogether because it's not an actual threat to the base? I'm just trying to follow your train of thought to it's logical conclusion - which is either missions progressing into an "actual" base defence or substituting custom maps for base defence maps.
Maybe I'm misunderstanding your example and/or original intent, sorry if that should be the case.
-

Yes, it would work the same as any other base defence.

But how would this be diffrent from a "standard" sewer mission site? What is the incentive here if the player can simply ignore the site alltogether because it's not an actual threat to the base?

No, the hypothetical attack from the sewers would still be a normal base defence, with normal consequences.
That exploration you mentioned would be a different thing, taking place in a different terrain.
-
Ah, okay. Sorry for the misunderstanding.
How exactely would these base defence mission be triggered and could they be defended against/avoided? Taking for example a small radar/interceptor base with a limited number of soldiers, would the player have any warning that an attack on the base would be forthcoming?
Also @Meridian, how would this interact with base defenses (if at all), or would these bypass base defense facilities alltogether?
-
no base defense missiles, no warning, no detection, no nothing
full surprise attack
-
That's what I wanted, yes. (Assuming that the standard missionScripts flags work, so you don't get a hard mission on month 1, or before a certain research, etc.)
-
would that new base defenses have own deployment properties, like breifing data?
-
I don't know, I haven't done it yet.
-
I faced that problem when making FTA, for nice solution it needs pretty invasive change so for my solution I end up with very dirty hack that is easy to code but even I don't like it :( Base defense mission is very special, it uses both deployments (attacking ufo and base defense), where `data` is taking from attacking ufo and all other properties are taken from base defense deployment. So with that, we can change only all base defense at once, without having separate briefing for the special one.
-

I certainly hope so, a separate deployment is necessary for, well, almost everything about my request. This includes custom info screens.
-
I would like to support this feature. One day, I would like do to arch mission spawn from base. It is not base defense but can be, without the UFO.
I am thinking in the line of Stargate Command. Start at gate room in your base, step through the gate, next level is another planet and etc.
-
Sorry, is this suggestion still being considered, or has it been dropped?
No rush, I am only asking to know if I should be accounting for such a possibility in the future.
-
still todolisted
-
I have implemented the above ideas in 3 separate independent features:
1. Instant retaliation: https://openxcom.org/forum/index.php/topic,10808.0.html
(as a replacement for comm waves workaround)
2. Option for retaliation UFO to ignore base defenses: https://openxcom.org/forum/index.php/topic,10809.0.html
(for alien attacks not targetable by ground-to-air defenses)
3. Mission sites at xcom base locations: https://openxcom.org/forum/index.php/topic,10810.0.html
(for mission sites)
Hope that covers everything.
Please test carefully.

Thank you very much, kind sir! :)
