Can there be some more randomization added in unit spawning to avoid dead zones?

    Ok so I thought I'd go back and have a look at making a mission on FATA, it's a map I've always wanted to make a mission on but I couldn't remember why I hadn't.

    So as I normally do I place my test composition down. It's basically a player with zeus, the ALiVE required module, Virtual AI system module, the Civilian placement and presence modules with no filters, extreme placement, and 35 pop cap all with debug turned on.

    I check the largest settlement on the map and it lights up all green and happy, but civilians are only spawning in a line?

    Yup sure enough


    I thought it was an issue with the map, but you up the pop cap to 100 and now it starts to look better


    finally 250 pop limit gives a good spread of civilians


    Now obviously that many civilians is stupid unless you enjoy single digit frame rates.
    I thought maybe I could really lower the spawn radius as I approach the town the building closest would populate and then as I walk through the town that "bubble" of civilians would make it feel more populated.
    But no, as soon as I get close enough to the town for anything to spawn they just spawn right down that line again.

    So is there any way to add some more randomization to the spawning process?
    I mean it would be great to see something more like this with a 35 pop limit


    At least that way you wouldn't be wandering through large portions of the town without seeing a single civilian.

    Couple more examples from the large town on GOS Dariyah



    Maybe it's only because I can see "behind the curtain" so to speak, but this sort of thing really kills the immersion for me.


  2. Interesting. Does this test hold true with vanilla?

  3. Yeah, although not as often because vanilla maps don't tend to have towns with as many buildings as modded maps do.

    But this is Pyrgos, it stopped spawning before it even hit the 35 unit cap I set


    I tried also at La Trinite on Malden, but literally couldn't get civilians to spawn there, they would spawn in towns all around, but not in the La Trinite.

    Also for some reason I noticed ALiVE's spawning the VR guy again.

  4. VR guy?

    This example seems less clear cut than your other modded examples regarding the units spawning in basically a line when using lower spawn numbers. What do you think based on your observations?

    @SpyderBlack723 any thoughts on this?

    ^ I take that back. The FATA one looks horrible but Diraya one is hard to tell. Same with vanilla. In both of those I don’t really see this “line” thing so curious to get a dev take.

    It's not about the line, that's just how I described the FATA situation.

    It's about entering a town and 90% of it is empty because the civ pop cap was hit spawning civs in one small part of the town. Eg in the above map pic from Dariyah you can see my camera is at the far end of town, if I walked into that town it would be empty until I got to the far end because that's where the civs start spawning in that cluster.

    In the Pyrgos map image you can see the big green circle over the town, in my opinion the civs should be relatively spread out across that circle instead they're all clumped together. If I did the exact same test with say a 250 civ limit then there would be a much more even spread.

    Also yeah VR guy, the civilian in the VR gimp suit.

  7. Ok I see what you mean. Good thread and good photos BTW.

  8. Is it possible Alive uses order the objects exist within the index files? Eg: checks proximity, then spawns down the list till cap is reached? I've noticed very similar behavior on Anizay, where some areas civs spawn in a cluster quite distant from the player.

    Have seen instances where I am at point A, they spawn at point B. Then later Ill be at point C and they spawn around point A (all within the module set spawn distance of course, but in a blob a fair ways away while many nearer potential spawn locations aren't used.

  9. @JD_Wang I have seen the same thing and have since started using the vanilla civilian spawner along with the ALiVE CivPop module to get civilians spawning in towns. I had a very similar behavior to the one you mentioned on most of the towns on Tanoa. Particularly the Lijnhaven area. The small villages would spawn stuff but the large town would not spawn any no matter what settings I used for civilians in the module.

  10. How's that working for you Nichols? I thought about experimenting with using the vanilla module to supplement the ALiVE Civs.

  11. Problem is they won’t follow the insurgency coding if spawned any other way other than by ALiVE from what I understand.

  12. In the past I've always used Engima's civilians script, which is excellent by the way. But as Heroes says it won't tap into ALiVE at all. I've only every used it for conventional battles or one off type missions.

    The limits imposed on ALiVE civs are primarily for performance reasons, both in terms of numbers of AI spawned and the script cycle to minimise overheads. I wonder if it would be possible to use something like Enigma as well - it would provide the numbers, whilst ALiVE provides the funk with the insurgents.

  14. Honestly all I'm really hoping for is for the civilians to be spread out across the cluster like in the 5th image where I just manually placed them.

    There doesn't really need to be many more, they just need to spawn all across a town/city rather than in the same small clump every time. In that FATA example, if you have the limit set to default, you will never spawn civilians anywhere in that town other than where is shows in the images. The outskirts of the town will remain empty.

    Without having any idea how the spawning works it seems like there's an array of places in the cluster that a civilian can spawn in. At the moment it seems like it spawns a civ at position 1 of the array, then pos 2, pos 3 etc, instead of selecting a random position in that array.

    Two things here:

    1. Clusters of buildings - Civs spawn in the cluster of buildings nearest the player. This is so you can have a higher density of civs in the local area, and not fill up the whole city with civs that the player can't see. Civs in the cluster despawn and the new cluster spawns as you move through town (same way CQB works). At least that should be happening. Have you tried moving through town in a vehicle rather than looking at it from Zeus perspective?

    2. Civ placement within the cluster - pretty sure this is as you say, in that the script cycles through available spawn points and places a civ. It's not so much an array of positions but the buildings themselves (and therefore spawn locations) are obviously static. That's initial spawn only though, and civs will move around. It may be possible to inject a little randomisation BUT...if you returned to the cluster 5 minutes after leaving it, all the civs would be in a different place, which might be a bit weird if you're patrolling on foot.

  16. @Friznit Have you tried moving through town in a vehicle rather than looking at it from Zeus perspective?

    Yeah as I say in that FATA example I even tried lowering the spawn range just to see if it would create a "bubble" around me of spawning civilians but no matter what direction I approach that town from that group you see in the first 2 images is where they spawn.

    As I say the only way I've been able to get civilians to spawn across the town properly is by jacking up the pop limit to crazy numbers.

    Does the green debug circle indicate the cluster size? Perhaps in this case it would work better if the town was split into 4 smaller clusters? If that's even possible without editing the map itself?

  17. Ill try and do some more controlled tests in Anizay,l. I could be wrong, but I believe some of the more extreme cases I saw they were spawning in more distant clusters than the one I was in. It was definitely a more distant objective but with the density of civ structures it may be the civ portion was much larger than the objectibe itself (and it was set to mapwide, unfiltered if that could also play a role).

    Initial impression was it was spawning by a list, but seemed to be based on max spawn range alone (900m or whatever default is). Will also reindex the map, could well be something funky with the index.

  18. Can anyone who has an up-to-date Anizay index please share it? @BvB ?
