It is not a mod API, it's a refactoring of the base game ai tasks that was not yet implemented but made available for modders to use.

You can find all the new options at that link Paski

@Tentharchitect This refactoring you refer to of AI tasks, is it a Mod API? Where can it be found? Thanks!

Maltiez refactored all the ai tasks and gave them all the options previously used for single tasks (like time specific stuff from the Idle Task) or completely new options (targetting dead entities). These refactored ai tasks just barely made it into 1.21 so the base game animals weren't updated to use them as they are time intensive to set up, but now we have the option as modders to come up with novel applications of the new options. What's more, there are now creature tags (huntable, predator, ferocious, state-sneaking, etc..) that can be applied to a creature or during a specific task and ai tasks can interact with entities based off of their comparitive weight and combinations of those tags. This all creates a lot more options for behaviors and I believe I'm one of the few figuring all the new options out at the moment, so I imagine others will come up with new applications as they explore it as well. Echoweaver

Yay! The updates are coming! I don't know what the revised AI will look like. I'm just happy to be able to install these in my new game.

We are Barack.

Oh we are so back.

A small update to get it working without crashes in 1.21, the ai overhaul and other 1.21 features will come later.

No chance for me to make it for 1.20.12, though if you want to come up with a compatibility file I'd be willing to add it to the next release Dragonchampion

Tentharchitect - I figured that's why they were built that way, sound-wise.  Gotta be some middle ground though, right now they're annoying, though I love their sound.  I should never get to the point where I'm shouting "Oh shut up!" at them. XD

Any chance to add PetAI compat with this so that you can command and use the cats in battle? 1.20.12, if that's okay.

They are ambush predators, the call was intended to mitigate player frustration of being ambushed without any warning but with the AI task updates I can give alternative options and just have them be almost silent Vinter_Nacht

Hello,

About those loud calls... Is there any way to turn down the frequency with which they emit them when they're nearby?  They do it a *lot* for an ambush predator ;) (I assume they're ambush predators?)

I unchecked the box saying they are 1.21 compatible. I suspect it relates to the antler system in addition to the riding system. 
I'm just now finishing the 1.21 update of the FZ series, starting on the animal series now but it will likely be a while before the update as I'm still in my 80 hours a week summer schedule until September 26th. The updates will probably come out after then.

The new ai overhaul should address some of this as I have more options to play with, but if you can confirm it was 200+ blocks please let me know. The call range is set to 120 blocks and while I've had folks claim it was farther, when tested it always follows the number set Coleroni

these things are hunter killer drones that spawn in groups and kill u in 3 hits.
they have a scream u can hear from 200+ blocks away
otherwise they are completely silent until they are attacking you
they can hide easily in tall grass 
they are faster than you and can take multiple hits from a spear before leaving you alone. 
playing on a 10- 15 population server with this mod between mid fall and mid spring these things can spawn in groups of 10 or more - based on in game experience
they do not seem to rest after a kill, they will continue to chase prey until there are none left in sight

Glad I'm not the only one that pinpointed my random crashes to this mod. Something is wonky, definitely not compatible with 1.21 just yet. Huge bummer. The crash is seemingly happening in-engine as well so it's difficult to pinpoint which mod(or mods) in the series are causing it. 

I'm getting a load of errors from all these Mods unfortunately. "Entity rendering crashes" mostly.

Ok, several mods in the FotSA series are mising closing braces at the end of the itemtypes\animals.json file, resulting in cryptic parsing errors. I've confirmed that adding the braces fixes the issue, and would provide a pull request, but I'm not seeing your packages on github

Love to hear it! I'm amused to report four more deaths to the Scimitar Cats. I did manage to trap a male. Then I ended up getting him a steppe lion roommate. Then they both died to a mammoth. Mistakes were made. 😂 Someday I shall domesticate a large cat!

Some of them are, but only the smaller animals and I don't have a compiled list of which of the 600+ entities are trapable. That said, I'll be updating the trapable section come fall and more animals will be trapable in the new large trap AlexIsAce

Loving all of your mods, they are so fun. 10 / 10 would die to a Scimitar Cat again.

I saw what you said about the animal trap mod compatibility patch and plan to go looking for it. But I wanted to ask about the vanilla game reed basket trap. Are any of your animals trapable with that one? 

Tentharchitect

Please add compatibility with Butchering mod. We love hunt on this creatures and cook them! Yammy!

Okay nw, I found them in game but they killed me instantly so I didn't get a good look haha. Was just going off the screenshots. Thanks for the reply, and great mod :)

So the Homotherium does have slightly longer limbs, and a different set of hunting behaviors to represent its cursorial habits. That said, this is one of my earliest mods and at the time the art updates to the base game animals hadn't started, so it was more informed by the blocky style of the current bighorn sheep and boars and such. If the base game ever adds big cats I'll probably go through and update their art assets, I just don't want to do it twice in case they make any big stylistic changes compared to my take on cats. Mauricio Anton was one of my main art references with these

I know this is super pedantic but I think possibly Homotherium should have slightly longer limbs and be a little more gracile? From what is known it was more of a pursuit predator and had stronger, shorter canines compared to its dirk-toothed relatives, making it hunt more like modern cats (chasing down prey, clamping on their neck and suffocating it). This means it was less robust and had diminished forelimbs compared to other Machairodonts; these traits were used to ambush wrestle down their prey and deliver slashing bites (a distinct hunting strategy requiring different morphology). Homotherium generally more lightly built with longer and comparitively more proportionate limbs.

I don't mean to talk bad about the mod, I love it and all others and I really appreciate your work. Just trying to be constructive. I'm just going off the images here so if I misjudged and this is already accounted for my bad completely! Mauricio Anton has really amazing images of Homotherium and Smilodon species to see the difference, I think it would be good reference. He's a very skilled artist and has collaborated with researchers to produce reconstructions, I've referenced him myself for Machairodont paleo art.

That's outside the scope of this mod, but there is the animal cages mod and some folks have made compatibility files with this mod series

hello, Is there a way to trap the cubs so i could move them into a more controled pen? 

Certainly! Translations are welcome erjiango

Hi, tentharchitect ，may I translate your mod into Chinese？

I'm not sure, that isn't a base game feature. You should check which ever mod adds that feature, I'm guessing butchering

how do i pickup the dead body ??? 

Tentharchitect I apologize, I'm realizing I'm having issues across a few mods and I believe a mod updater I'm using isn't behaving properly. Sorry again!

This bug was fixed in 1.0.20, have you updated to the latest version? Steele_Rex

Hello! I have found an issue with the full body taxidermy with all saber cats. They can not be placed on the ground.
I discovered this in a survival world with the male northern saber cat, tested all three species (male, female, and cub varients) on different blocks in a creative world, and then went to go file sluething when none of them worked.

I have an extremely surface level knowledge of coding but comparing to the pantherinae taxidermy file, the saber cats are missing a ground storage tag at the beginning of the file. I tried a copy and paste fix, started the game and still was unseccessful placing the saber cat taxidermy on the ground. I created new items in the creative menu and it still failed. I started a new world and it still failed to place.
That is what I have tried and believe is wrong, but I don't have the knowledge to fix it. Would love to get this working so I can make a proper hunter's lodge!

The meow, tho

can i pet that daw... i mean cat.

Fantastic! Thank you for the answer

Voici une amélioration de mon ancienne traduction. fr.json

All animals in this series are domesticable, just got to breed enough generations so the attack and flee behaviors are disabled. This is coded so it'll be whatever the current base game generation count is

Are the critters in your mods domesticable, or any plans to make them such if not?

Tentharchitect

Thanks for the clarification!

That's all fine, the Entities interact mod was patching in a fix I've since fixed in the mod itself, I imagine whenever DnD updates their mod they'll remove that patch causing the warning

I get a server warning with the newest version:

Do you know, if this is relevant/game braking?

I love smilodons so much it's actually unreal. Fantastic mod!!

Hmm, I'll look into locking the group spawn cap at 1 instead of scaling with player population next update. I'd had a couple similar reports on small servers early on with the pantherinae mod but was never able to replicate it. If the group spawn cap rounds up, a spawn cap of 2 while 2 players are online might create the circumstances you've been seeing 

We're running 3 people, server stops when no ones on, Usually there's only 2 of us on at a time, weekends its all 3

Tentharchitect

If i knew how to I would. But if any other modder wants to I would be very happy to see it (and/or the sabtertooth club).

Tentharchitect

Just an FYI, your cat skins look fantastic on floors as rugs, but if you put one in front of a door, you can't get out.  The skin raises you up too high to fit through the opening. :(

Hoooooooly crap, Tentharchitect 

You were NOT kidding when you said these things are mean and nasty.

Tentharchitect

Could you please add a Saberooth Skull Helmet?
Thanks in advance!

I've got both of the big cats mod on our server and they're spawning like everywhere. Like we constantly hear them roaring, they're terrorizing us and we barely made a log hut to hide in. Is there a way to make them like more rare? I thought they'd be a little more harder to find than they are (at least in my server, and I didn't touch any settings for it, idek if there's a config for this tbh)

For example, we are in a chunk, there is like 4 big cats next to our crappy little log hut thing. If I jump across the river and run like 10~ blocks east, there's 2-3 more cats over there, if I run south from there a good 20~ blocks, there's another group of 3-4 cats. Could the issue be that I have both the big cats mods? I mean the Pantherinae and Machairodontinae mods. I also have the dogs one of your mods installed too, but they spawn pretty decently

Thanks for bringing the issue to my attention, seems like it was a weird combination of things that meant that when I used my testing set up the bug wasn't present.
The saber cats weren't spawning in air blocks, only grass/snow/gravel while the carcasses could spawn in air blocks as well, dramatically increasing the number of places they could spawn, and the carcasses' spawn rate was misformatted so it was defaulting to a much higher spawn rate than intended. Between those two changes I was seeing the saber cats spawning before the carcasses 3 out my 4 tests. Please let me know if you continue seeing carcasses spawn more frequently than that, I might add variant carcasses so they stop spawning in the gap of climate conditions where neither smilodon nor homotherium spawn if needed.

I have the same problem as Bringitonwimps and PetMudstone. I have only seen carcasses (without actual mod texture, just bones)

Edit: mod looks great!!

I can confirm what bringitonwimps says. Have been roaming about and only found saber cat carcasses with no actual sign of proper saber cats.

Thanks, and that it would. I don't have plans to make either of those in the near term, but long term it might happen!

I really like these creature mods, It'd be cool if there was a Terrorbird/Elephant bird mod

I'm not planning on doing any weapons Hydromancerx, but you'd be welcome to make an add-on mod if you're inclined!

Maybe, though I'm realizing with so few species there are certain climates where only the carcasses can spawn. I might need to do something tricky so they only spawn in the climate conditions of each species, rather than the min and max of all species combined.

so not sure if there is an explanation.... but we only find cat carcasses, we have not found any of the cats alive.  maybe bad luck?

An idea from Frostburn having a Sabercat Skull Club as a weapon. Also a Sugliin (an anter polearm) made from antlers.
Thanks in advance!

Bobosaw Agreed. Although I also think the game lacks more critters too, like insects and birds (actually flying ones, not just ground walking). Imagine forests having singing birds hopping through the trees and in the sky you could hear and see predatory birds eyeing for bunnies or whatever in the open plains while various little insects (besides Butterlfies) zip around.

Super exciting! Your models are always beautiful

Procyonidae indeed needs some love! We'll see how long it takes for me to get around to them but I suspect it'll be sooner than later.

I totally agree Bobosaw, the isolation of Homo sapien mode was cool to explore but I feel like having the world be teeming with animal life will only make the experience better.

I'm genuinely very excited for the additions of Holocene fauna. Honestly Vintage Story was missing the vibrancy that Fauna can bring to the world especially in the Human setting. Adding more danger and diversity can only be a plus in my eyes. Keep up the great work and I will refrain from any kisses in the future ;)

"The cave bear (Ursus spelaeus) is a prehistoric species of bear that lived in Europe and Asia during the Pleistocene and became extinct about 24,000 years ago during the Last Glacial Maximum."
Looks like it was Late Pleistocene, but just barely (pun intended).But yeah I understand things getting out of hand. I am looking forward to the Short Faced Bear though. Also I was going to ask about Chapalmalania which is related to pandas and raccoons. But that went exinct in the early Pleistocene. So that much too old to include.That being said living relatives like coatis, ringtails, kinkajous, etc. Would be cool. The Procyonidae need some love too!

All of those are likely except the Cave Bear. To prevent my scope getting out of control I'm keeping to the Holocene and the occassional Late Pleistocene animal that died off just before the Holocene if I like it enough to make that exception

Tentharchitect

Ooo Cave Hyena sounds cool!! I hope you do other hyenas like the Striped Hyena (Hyaena hyaena), Brown Hyena (Parahyaena brunnea) and Aardwolf (Proteles cristatus). Also will you be doing bears? Such as the Sloth Bear (Melursus ursinus), Spectacled Bear (Tremarctos ornatus), Cave Bear (Ursus spelaeus) and Short Faced Bear (Arctodus simus)?

Another awesome fauna mod, thank you, Tentharchitect!

It might, I made it during 1.19.1 and nothing changed for 1.19.2

im guessing this wont run on 1.19.0

😂 Glad you're all enjoying it, I'm sure my partner would appreciate you not kissing me as well Bobosaw.

I'm almost done with all the dangerous terrestrial predators now, so this'll be as bad as it gets save for maybe a cougar here, or cave hyena there. Then we have the dangerous herbivores to look forward to!

LET'S FUCKING GOOOOOOOOOOOOOOOOOOOOOOOO. I could kiss you right now (I won't out of respect for my wife)

Oh great, even more brutally dangerous predators. Just what we needed...

And I will download it anyway because I'm that masochistic!

So awesome! Thank you for making these!!! <3

holy!! i just refreshed... no way!! awesome!
