ASF - Autonomous Sex Framework

[skybird]

Well I gave up on it.

The mod works but the sex locations remain a problem. Some of my mods probably reason for it.

Yesterday I was in thieve guild and activated all the possible combinations M-F, F-F and M-M and lowered aroused. 3 animations started within few minutes but theNPC all vanished I literally saw them pop off and this was indoors. So I tried SES2 with ASF not active and tested it with random sex mod and that works great. No pop offs and I dont need to search to much where the NPC are having fun. None of em disappeared.

 

I tried ASF with only ASF aroused as option but have the same problem.

 

What I havent thought about is if my save game is now a culprit as I didnt do my testing with clean saves.

I have sadly broken ASF smh and it's no longer working for neither a new game nor my existing save. It used to work fine but I have definitely screwed up somewhere, posting lots of logs below. To be clear, my normal sexlab mods work so it's an issue specifically with ASF. Scenes don't start for npc and if I accept a scene with prompt, i get buggy screen and eventually freeze like the image below:

I see that you asked someone for logs in papyrus.0log so i have done that with 100% verbosity

I've been having the "teleport to a random location" issue as well, from the relatively new "Free Use" option in LMAO, which currently only is set up for NPCs. I've attached a log. Scene starts around 6:30:51pm, I believe. This happens for me regardless of whether I have preferred locations turned on. I've also included a screenshot of where they teleported to.

Another data point for you.  I use the mod "Orlok Castle"/FalkreathCastle.esp as a home.  The characters there (servants and guards) where disappearing for ASF events.  I also have Use Preferred Locations unchecked.  I found a heap of about 3 ASF sex events all occurring in one spot (a SweepingIdleMarker) in the entryway.  Characters were stacked up halfway to the ceiling at that spot.  So I think maybe there is an issue with sex scenes not ending properly -> building a stack of scenes, in addition to the location issue -> choosing a spot already in use.  I looked and I don't have a log file for that event.

I also experience this, but primarily in a few locations from JK's Skyrim, like Nightgate Inn.  I assumed it was due to the modded cells.

[bitnuke]

If i don't have access to scripting or CK, just the keyword file, how would i go about the following:

 

- Include only bandits as initiators

- Include only naked (torso armor slot empty) females as recipients?

 

The first one is just a "would nice to have" feature, and the second one what i'm actually looking for.  I've been searching forever for a matchmaker that simply pairs bandits with naked females and arousal threshold. Every other matchmaker that offers this is either buggy, crashy or both.

Can confirm that this doesn't happen in version 1.0.2, just the new one.

I updated the description of this mod. Hopefully it is clear now that this mod is a framework like SexLab. If you installed just SexLab nothing would happen. Because it is a framework. You need to install mods that use the framework in order to see sex scenes. 

 

ASF is the same. The only difference is that users can create their own ASF sex mods very easily using just SPID config files. No need for Papyrus scripting unless you want to build advanced features. Alternatively you can install a mod like LMAO or SES2 to that use ASF.

Making bandits initiators is easy. SPID file can target bandit factions and assign the keyword ASF_Initiator_Included. I leave it to you to google and research how to create SPID files and assign keywords with them. SES2 is an example and has some rules targeting bandit and forsworn factions.

 

Making naked torso recipients is sadly more difficult. You can easily make clothing items cause wearers to be recipients. Use KID to assign ASF_Recipient_Included keyword to the items. These can even be bondage devices or jewelry that leave the wearer largely naked. SES2's KID file does this. Or you could create an invisible clothing item if you have a bit of modding know how.

 

But to make completely naked actors recipients you will need to create an SPID spell and distribute it. Papyrus coding is required.

 

I has success with Deviously Enslaved doing something similar to your goal. When the player or followers are wearing bondage collars they trigger sex. That mod also makes the player and followers temporarily friends of the bandit faction. Which is important. ASF will not pair enemies together because that causes glitchy behavior. Actors must be temporarily added to a friends faction to be valid ASF pairing options.

 

Unfortunately Deviously Enslaved is not perfect. It does have bugs. But it works okay.

@skybird @zztai @rjn @nunyabidnez @lazypeon I released an update (2.0.3 RC) that might help with this issue. There is a small chance the issue is fixed. I  examined the relevant code and only found one possible cause for why scenes might center on the 0,0,0 coordinate.

 

This release features two things that may help debug. First there is more logging when centering sex scenes. Second this release contains some temporary test code that allows users to disable portions of ASF's scene centering code to help isolate where the issue is happening.

 

First would you mind testing the new version with ASF's default settings to see if your issue persists. If there is still a problem download the attached file. Install it as a mod. It is a simple JSON config file that you can open and edit. 

{
	"int" : 
	{
		"skipcentering" : 0,
		"usepreferred" : 1,
		"useactors" : 0,
		"useidlemarkers" : 1
	}
}

 

You can tweak what things ASF might try to use when finding a center for a scene. 0 = false and 1 = true.

• UsePreferred: 0 —Will not attempt to center on any preferred scene locations, whether one of the actors is seated in that location or not. 1 = Default behavior.
• UseActors: 0 —Will not attempt to center on an actor even if they are standing and seemingly a good location for a scene. 1 = Default behavior.
• UseIdleMarkers: 0 —Will not attempt to center on idle markers, even if they are unoccupied and seemingly a good location for a scene. 1 = Default behavior.
• SkipCentering: 1 —  Disables calls to SexLabRecenterAndRotateScene(). This disables much of the new centering code in ASF. 0 = Default behavior.

The game loads JSON config files when you load your save. If you change the config options you do not need to exit to the desktop to reload. Instead save the JSON file and exit to the main menu. Reload your save.

 

You can confirm that the game loaded your updated settings by checking the ASF log. Every time ASF starts a sex scene you will get a log entry such as this:

 

SexLabSetSceneLocation() Thread[2] Found ASF_Test.json, UsePreferred=TRUE, UseActors=False, UseIdleMarkers=TRUE, SkipCentering=False Actors=[...]

 

If you do not see that log entry then your JSON file is broken or not installed correctly. Or ASF did not start any sex scenes.

 

Edit: If the issue persists in some configurations of ASF_ Test.Json please share updated logs with the issue happening. Hopefully the additional logging will shed light on the problem. I appreciate everyone's help in diagnosing this. I need your help to find why it only happens to some users. You five have been very helpful.

Just from some quick testing:

 

2.0.3 as-is: issue still happens

 

2.0.3 with attached JSON, without changing the JSON: issue no longer seems to happen.

 

Side observation: Might just be a coincidence, but it seems like sex scenes start a lot more frequently in ASF version 2 than in version 1, with the settings being the same where applicable. Is this expected? This isn't a problem, exactly, just something I noticed.

[kaxat]

@lazypeon That is very strange. And good to know.

 

The default ASF_Test.json disables one thing. Using actors as a scene center. I purposefully chose that default. The logs indicated that everyone affected by this issue was having ASF fall back to centering on an actor. Which means ASF was falling back to the same behavior it did in v1.x. Yet you have confirmed the same issue did not happen for you in older versions. Odd. But helpful.

 

The real problem probably happens inside of SexLabRecenterAndRotateScene(). Which again should behave similar to v1 in this situation. But does not.

 

If anyone can upload logs where the issue continues happening that might help me discover the root cause.

 

I suspect it is related to a mod like SexLab Separate Orgasms. A mod I do not have installed but I noticed most all of you do. However one person tested with that mod disabled and still had an issue. So maybe not that specific mod. Just something like it.

 

In theory this issue would actually happen less frequently in v2. Because of the new Scene Positions feature. When that is enabled and the KID file is working correctly then ASF should often be able to find an empty place for sex. When ASF finds such a place it will not center on an actor. Preventing the issue. Ironic that my first recommendation to everyone was to disable Scene Positions in the MCM. That would likely make this issue happen more often.

Could be coincidence. Or perhaps it is one of the bugs that v2 patches. There are a dozen bugs that v2 patches which were present in v1. All of them rare issues. Some of them could reduce the number of scenes.

 

Related rant: The latest version 2.0.3 helps alleviate a semi-rare bug in SexLab. SexLab can sometimes leave an actor in the SexLabAnimatingFaction after the actor is done animating. Largely preventing them from joining new scenes. This is a known issue in SexLab and it attempts to self-correct without scanning the area for NPCs in that faction. Which is great for performance. But means that SexLab's self-correction is haphazard. I made ASF check for the same issue when it has trouble adding an actor to a SexLab thread. A logical time to aid SexLab in correcting. Especially important in P+ because as far as I can tell that version removed SexLab's self-correction code. Presumably Scrab had never encountered this issue and felt the code was no longer needed. But it does still happen. The longer you play the game and the more actors that have sex, the more actors it will impact. With sex heavy mods like Slaverun you roll the dice more frequently and slowly accumulate more actors who refuse to have sex under normal circumstance.

 

I recently had the above issue happen to my player character. SexLab attempted to start a thread with her and she began pathing to the location. But the only pathable route to that upstairs location had her walk through a door with a loading screen. As soon as she walked through the door SexLab gave up and stopped trying to start the thread because some of the actors were no longer in the loaded area. But it also left my player in the SexLabAnimatingFaction. Just one example of weird circumstance where this bug can happen. And it can semi-permanently cause an actor to be SexLab invalid. So if you ever have one specific actor who never animates you might check their factions.

[Messiah2002]

Misspelling？

[kaxat]

@Messiah2002 Good eye. That is a mistake. It should say "Includes an actor in..." Looks like two MGEFs have that issue.

[johnhamm]

Would it be possible to log the scenes using ASF for unique NPCs? If there's a counter or something for 2 NPCs successfully pairing it could be used as the basis for an NPC relationship mod. Something like: Hulda and Sinmir have had 4 scenes through ASF that have been tagged with foreplay, so a mod that uses ASF could categorise them as early stage lovers and start an oral scene between them, or some other scene/dialogue

[VahzahVulom]

any chance we can get a list of mods utilising this

[kaxat]

@VahzahVulom Not many mods yet. Just SES2 and LMAO. Hopefully more soon.

 

I have begun working on patches for Public Whore and Radiant Prostitution. But I tend to get bored and resume playing the game. Progress is slow.

 

@johnhamm That sounds like a mod that could be built.

[VahzahVulom]

are there any plans for a mod similar to SexLab Nightlife in functionality that uses this

[layzpeon]

I'm playing a version of LMAO now that includes the player in its ASF setup too, so I've been testing that. Something I've noticed is that often wherever I end up in my sex scene, people around will often sandbox right on top of me (usually my follower, since I have followers set to sandbox during player scenes in the MCM). Is there a setting that can prevent this? I've tried messing around with preferred locations a bit but I'm not sure it's helping. I still have that JSON you included above and haven't changed anything in it.

 

Edit: Also sometimes we end up floating ~1 foot above the ground.

 

Edit 2: Also sometimes characters are not put in the correct gender positions.

 

Edit 3: Setting "useidlemarkers" to 0 in ASF_Test.json resolved the first two things I mentioned.

Edited March 15 by layzpeon

@layzpeon @leighn Unfortunately that is a problem that needs to be patched in SexLab. And your version of SexLab evidently does not include a patch. Personally I use P+. But that requires a new game. Osmel's Tweaks lists this as one of the things it patches and it does not require a new game:

 

Quote

Filter Gender Tags Animations:  If "Enabled" scenes will automatically filter and sort the actors position to fit with the current animation, unless doing so would result in the scene having no animations at all.

 

I have not tested with Osmel's Tweaks. But I hear good things. It is not as fast as P+ but still provides a speed boost.

 

How often are actors not sorted into the correct gender positions? Is it 10% of the time? 50%? 100?

It's not frequent, 30% at most. Just enough to be noticeable. I'll give Osmel's Tweaks a try.

 

Edit: I've tried it, and it doesn't seem to help with this particular issue. From what I can tell all it does is makes sure that if the scene is Male/Female, no MM or FF animations are used, but doesn't do anything about who goes in the M and F spots in the animation. It's a nice mod to have overall though, so I'm glad you pointed it out. But it seems like P+ might be the only real solution. It's a fairly minor problem from my perspective so I'm okay with this, but I thought I'd let you know.

Edited March 17 by layzpeon

[kaxat]

@layzpeon Filtering out MM and FF animations is one thing. Sorting is another. That setting specifically says it does both. If it is failing to sort that might be a bug. You should report it to Osmel.

 

Animations have "positions". Slots they can put an actor in. Vanilla SexLab hopes animators put Females first then Male. FMM and not MMF. But the documentation that advises this is buried. Some animators have never seen it and do not put the expected gender first. Notably Femdom animations often  reverse it. Roughly 20% of animations go against the norm.

 

So now mods have a problem. They can sort actors using SexLab's sorting function and send them off to animate. They can follow more of SexLab's recommendations and provide animation tags instead of a single animation. That way SexLab has a variety of animations to choose from. SexLab will randomly select one. But will the animation be FMM or MMF? The mod can not know that in advance. SexLab chooses after the animation and actors have been sent to it.

 

A lot of mods avoid this issue by limiting which animations SexLab chooses to only those that are sorted as expected. They limit animation variety so that you never see some of your installed animations play. Which hides one problem from plain view while creating a new hidden problem.

The obvious solution is for SexLab to resort actors after choosing an animation. Then all animations can play. This is what P+ does. Osmel's tweak specifically claims to do this too. If it is not resorting actors that is likely a bug.

 

That said there are rare animations that mistag a gender position. The animator accidentally marked the male position as female. Out of 1000 installed animations I have found 5 with this issue. That is a bug in the animation itself and must be patched there. For the most part those patches already exist. If you only tested with one animation then you might have encountered the 0.5% chance of having an unpatched animation pack. In every version of SexLab you will notice issues with these animations. Such as females in the male position not getting a strapon when settings say they should.

I tried the spell to initiate sex scenes in Markarth Inn, it works well. All scenes only happens when the PC finds an empty bed.

And when I tried to initiate scenes in Cidhna Mine, it doesn't work now. Seems like scene cannot be triggered when there is no bed? How can I make scenes happen just where the player stands? On the ground?

 

Btw, I really like how the framework allows me to input keywords manually. Good job!

[kaxat]

@lazycai Thank you!

 

No combination of settings will cause ASF to require beds. You might test more to confirm that is what is happening. If it is that is a bug.

 

SexLab can require beds. You might check your SexLab settings.

 

@layzpeon I think I found one more thing I can do for Vanilla SexLab to help it choose the correct animation set more frequently. It will be in the next release.

[layzpeon]

Nice, looking forward to it! Just want to add that I'm really enjoying what ASF adds to LMAO, so thanks for the mod!
