BrainTweaks 0.2.8

Same experience here, it seems like whenever the bot is not "easy" difficulty, they just instantly aim for head-eyes. Additionally, seems like bots prefer to teleport now instead of running. Noticed this behavior on goons at first, but raiders just tp-ed on my head after detecting me, and I don't even know anymore.

I am at a loss here. I don't encounter this kind of insta headeye behavior. Nor do I encounter this teleport issue at all. (I am using a debug mod of mine to see bots positions and I can see where they are.

What I see is that they are quite accurate to detect my sounds and will aim at me even if they don't have a line of sight.

Some of them guards are really annoying and shoot straight to the head but I expected it because I did not tweak them yet...

What you should do is try and tweak the bot brain that annoys you most and report a setting that works for you so I can incorporate it after some tests. Sending me the whole modified brain file is enough since I will be able to detect changes.
I know this will not be perfect in a few releases, the brain tweaking is a long process and will take some time to get somewhat right.

I just died to a grenade. Every other time it's head/eyes. I can't move without dying.

Same here. PMC almost always headshot me: Head, Eyes, nape etc. Very often from ridiculous angels and distances.

I even tried lowering the difficulty to no avail. I looked at the bot brains but there's like: pmc, pmc_bear, bear, etc. Which ones do the PMCs actually use?

I tested it with a self compiled version of sain. From what I can tell all the combat brain parts are taken over by SAIN. So it IS compatible(ie: no lock-up). I would not be surprised if SAIN took over most of the functionnalities of this mod to the point it would do basically nothing (appart from taking startup time on your server)

I am still not using SAIN myself because the bots do a lot of weird stuff, like going up stairs and teleporting back to the lower floor in a funny loop. Plus the bots are still static taking a spot behind a cover and waiting for you to come during the all raid.

So ATM SAIN is still off the table for me.

If you remove Braintweaks do you still experience the same issue ? I don't really see why BT would make them aggro or not but ... this is Tarkov after all and we don't know all the internals, so anything is possible...

As a side note I tried Phen's Roaming Bots and did not find the bots really more "roaming". Did you notice any change with this mod ? (I only tested on reserve so far)

Well the mod does not make them miss or not shoot the head. The mod makes them take a bit longer at the initial engagement start for them to have the authorization to zero in on your head.

For example a normal scav will have a 55 second delay from its first decision to aggro you before it can opt to target your head willingly.
This does not mean one or two bullets will not fly in your face, because scattering rng...

This also means that if it aggros you and take some time to reposition and take a shoot at you, that delay could already be elapsed and you're back to normal target choosing.

And one other bad luck moment could happen to you: each time one of your bullets touches a scav it will move its aim from 27 to 36 degrees... Which is enough to make it shoot you straight in the face while it was aiming at your stomach... And its scattering will be affected by its overall damage. The more damage the more scattering, so on a long term it should make them bad shooters, but from time to time it could mean real bad luck.

And make sure those are scavs and not Raiders, because raiders are way more difficult beasts.

MOAR handles spawning (when, where, how much, with which gear)

BrainTweaks handles bot "capacity" (line of sight, fov, hearing sense, reaction time to sound, body part targetting...)

So yes the two are complementary.

The Goons have a range of vision (and FOV) which is insane. And in EFT the "vision" is weird. I maintain a mod named Enemy Markers and did some experiments with raycasting (the same way the game does) and you "see" bots in impossible places because one pixel is reachable... So yes they spot you "magically".

Then add to this their hearing sense and you're toast. Without SAIN and That's Lit you can only blunt them...

This mod:

• reduces the vision range and FOV
• reduces the target choice at first contact (body parts to choose from)
• adds a longer time before they can choose any part as a target
• reduces their hearing (iirc),
• they have a longer reaction time after hearing a sound
• reduces their full-auto burst time (how long the finger stays on the trigger) in order to get less bullet in you.
• Add more time between each single shot (birdeye)
• Adds a bit of scattering to their bursts (can play against you if they are on your torso and the scattering RNG decides to move 3° up)
• make them miss some of your grenades
• make them miss some of your tripwires

That is what I remember doing. But this may not be enough yet. I need some play testing myself and some feedback. So please don't hesitate to tell my what you think could still change!

So... coming from a very aggressive play style... APEX and TitanFall multiplayer were my hometown for years... Goons with this mod are easy mode.

Birdeye runs around in the open more often... Knight and Big Pipe suppress in shorter bursts and start running sooner to push... which gives you a better chance to hard angle them from any kind of hardened cover (boulder, building, vehicle).

Now... in the open... Shoreline east approach to radio tower ... Woods caught out on the road.... you're dead instantly or 3 limbs blacked and running. They do take a moment more to aim, but you're getting suppressed with effective direct point fire just the same.

It's... fair enough... not OP broken instant reload, 2 bullets per shot, head eyes instantly... but it is also still easy to cheese them if you know how.

Great work flir, this mod rocks!

Oh and I also play with all bots, yes Scavs too, on 100% spawn chance for IMPOSSIBLE with Acid's ABPS and APBS mods behind Braintweaks.

Thanks for reply Flir. I'll continue to playtest it. What I've been doing is using dynamic maps and toggling the bosses marker to see what they're doing. What Plot_Device says is accurate. If they spot you outside, it's basically over for you. Shoreline and Woods is essentially a death sentence since they can beam you and have no issues finding you. Fighting them on Customs is way more manageable but still dangerous.

Zandy... found a new trick for Goons on the 0.2.8 version (0.2.7 had the same effect), Goons can still throw grenades at you, but they also seem to rush when YOUR grenades land near them... so if you can get an M67 on the way to them, they scatter or hard push you every time... gives you a chance to get sights on while they're still in animation.

Tested on Woods and Customs... bought me 2 more seconds to rotate each time.

It should...

Which one in particular ?

In general each server brain mod does the same kind of things. So Choose one for the features you want and keep it.

Or learn what each mod does and pick the right load order to apply each mod.

I already explained in the comment section some interactions with other mods.

The mod changes brains for each "difficulty" setting. So if you set "impossible" in the settings you will get the "impossible" version.

The mod changes some settings (from base game) using the same system.

Mainly it tries to make the bots less laser like on your head in the first 10 milliseconds you see them.

It removes OP skills like running without loosing stam or making noise, reloading instant...

It also adds possibilities for the bots to miss the fact you thrown a grenade at them etc...

example:

With the mod SCAVS should have chances to miss your tripwires:

• 50% on easy,
• 30% on normal,
• 15% on hard
• 5% on impossible

In the base game they will never miss your tripwires and always spot your grenades and run from them.

From what I understand (I did not look at the source code) APBS will make the bots have a somewhat matching level to yours and will change the generation process (which we do not touch at all) to give bots better gear with higher levels.

We only touch to the brain presets (reaction time, hearing distance, scattering, full auto burst length...), they only touch to the generation presets (ammo, weapons, weapon mods, equipment...).

Should be safe to use both.

Yeah, just wanted to be sure. Thanks

Gonna try playing with this mod

Btw, trying to look into those brains a bit, where can original files can be found, and what exactly controls the chance of bot running away from grenade thrown into him?

Scavs are "assault" (AFAIK)

Original files are in the "SPT_Data/Server/database/bots/types/" directory

I use this command line (Linux) to copy original files to my db/bots:

for i in ../../SPT_Data/Server/database/bots/types/*; do
    jq 'del(.appearance, .chances, .experience, .firstName, .generation, .inventory, .lastName, .skills)' $i | jq 'del(.health.Energy, .health.Hydration, .health.Temperature)' > `basename $i`;
done

This is a basic "jq" usage to remove some unwanted values from the files...

Interesting. Checked your mod files, and while scavs had their

CHANCE_TO_NOTIFY_ENEMY_GR_100

lowered from 99 to very low amounts, PMCBear and PMCUsec (brains used by AI PMCs, judging by botmonitor) still have it at 100

I assume you mean that scavs are idle when using this mod only ? And if you remove this mod your scavs are entering combat mode again ???

I did not notice that. On which map did you observe this comportment?

Are you sure you don't have any other mod touching the bots' brains ?

Yes, only with your mod.

I noticed it on Interchange, Ground Zero and Woods so I think we can assume it happens everywhere.

Other than BigBrains, no.

I have not changed the "Hearing" of the scavs. Probability to hear, distances and reaction time are left as vanilla.

I have not changed the "Look" either.

In fact I only changed those settings so far:

Section: Aiming

"ANY_PART_SHOOT_TIME"
"BASE_HIT_AFFECTION_DELAY_SEC"
"BASE_HIT_AFFECTION_MAX_ANG"
"BASE_HIT_AFFECTION_MIN_ANG"

Section: Core

"ScatteringPerMeter"

Section: Grenade

"CHANCE_TO_NOTIFY_ENEMY_GR_100"

Section: Scattering

"MaxScatter"
"MinScatter"

I have only tested on Factory, Customs and Reserve yet. I'll go and test on the mentioned maps to make sure. I have BigBrain installed too (waiting for SAIN... to use it) so I think we can discard this mod from the suspect list :p

But as Drakia says on his mod: this mod is meant to be used as a library and will do nothing by itself. So it should not change the bot behaviours at all.

Well something is definitely going on. I was sprinting at them from behind a corner and they did nothing. When I run from behind they did not react even though I was like 10 meters away. Maybe reapplying default values would do the trick?

Anyway, scavs staying idly instead of roaming around (let's say, a sawmill on Woods) is a strange behavior. I will try to make some more testing at night/early morning tomorrow.

I went to ground zero and confirmed this: I ran into a scav's face and it did not even see me. He was just idling around while I was putting my gun barrel into his left nostril...

Then in the garage I spotted two of them and they spotted me when I arrived, but a PMC had already engaged them 20 seconds earlier...

I'll investigate this more...

Nope. This means neither the default config/config.jsonc nor the config/userconfig.jsonc is found.

This is not good at all. Are you sure you unzipped the full archive into the root folder ?

This should give you a directory: "user\mods\flir-braintweaks\config" containing the "config.jsonc" file. If you don't have this file alongside a README.md you are missing something...

When you see this message, the module aborts and does not load.

Fairfight mainly rebalances the Rogues (ExUsec) and mine do this and more.

If you only want to go on Lighthouse kill rogues, Fairfight is enough

If you want to be able to tweak all brain types BrainTweak is the way.

If you install both, make sure Fairfight is loaded last because it does modify less things (basically only ExUSECs) but i would advise against it because you would always wonder which mod is doing what...

Choose one and keep it simple :p

Not really. It just blunts them a bit. Don't expect the goons or the raiders to be braindead :p

Just makes sure they do not shoot straight to your head in the 10 first millisecond they see you.

Take care some rare bots seem to find a way to throw a grenade once in a while... but overall it's way better now.

thanks for the warning. yea i dont mind dieing like 1 in 5 or 6 raids but when it happend twice in a row i went looking for somthing to help whilst sain is unavailble

I have no idea if the tweak affects the tripwire detection... Could you test and report back ?

i will try it

Thanks again for creating this mod

Did some small Test Runs on Customs and Factory with Scavs.

So far as i noticed when they are in Combat Mode aka. "running after the Player" they tend to ignore the Tripwires (only running away after they got triggered) other then that i often saw them just being disarmed.

So do you manage to get some kills with the tripwires ? Or not at all ?

None at all.

I have no skill in graphics, but thanks anyway :p

light mod it is...

Thanks for the kind words.

Pretty sure it's a no cuz this is pure server side tweaks

It is server side and only changes ratios applied to already existing calculations. So no.

Yep this is definitely something on my list!

Wonderful! Thank you

I'm a bit naughty myself in that I directly edit the spt data configs (make a copy first) - and in there one of the things i tweak are the "Grenade" sections of each bot type (lot of work as there's over a dozen) - I change "grenadeprecision" to 0.4 for everyone. 0.1 is the std setting with some deadly types being lower than that. I tweak lots of other stuff like bot response times, their body part health values, hearing range, basic aim scatter and time to narrow the aim (ur toast - or at least need to run for cover - if you can't nail em in the first volley or two) - but the one i cannot figure out in 3.11 configs is the way they run so quickly - so i'll try this to see if it fixes that There's also configs in globals.json for each bot class - I can't figure out how they relate to the "Bots" folder stuff so just duplicate my tweaks in both.

I don't know if this can help you NerfBotGrenades

Oh I meant throwing grenades at bots, not bots throwing grenades at me. but thank you!

You definitely need No Boss PMCs by DrakiaXYZ (I use it myself).

My mod only tweaks each brain independently.

DrakiaXYZ disallows PMCs from being able to choose the Boss brains.

If other mods do change brain settings then the one that is loaded last will "win".

So this would not "conflict", but could just slow down your server start for nearly nothing.

That being said my mod also removes some cheats from all bots (insta-reload, super-stealth, eternal stamina) and remove their ability to throw grenades.

SAIN confirmed a new version soon™

What? no way....

Should be there someday. I compiled it from the source yesterday and it "worked"... kindda.

Bots were running backwards and not shooting at me, always searching cover.

But at least it compiled and did something in 3.11... so . It will come.

You can just extract in the server files as usual (the zip contains a user/mod structure)

If you don't intend to tweak bots yourself you can stop here and play :p

If you want to change bot behavior for yourself copy a bot brain from `db/bots` to `db/userbots` and happy hacking !

Same for config: If you want to disable some feature (say you like your bots spamming grenades at you) you can copy `config/config.jsonc` to `config/userconfig.jsonc` and adapt to your taste.

All this is just to avoid losing your changes upon next release :p

Thanks for clarifying and mod! I really needed "no grenade" after dying 3 times in a row in ground zero from grenades

Same here! In fact this mod started because I was so annoyed of being grenade spammed...

Be aware that I still see some bots throwing nades from time to time. But clearly not as much as without this mod. This will be one of my next quest: remove all the freaking nades from their pockets :p

Ok so I released 0.2.1 because talking about nades I felt like my last raid had a tad too much ...

Haven't tested yet and you already updated couple times well done , gonna test tonight after work with latest version to see how its work and I definetely believe its better than vanilla.

Eager to get feedback and suggestions...

Try again, the project was still private

I'm so bad at releasing a new mod I always succeed to b0rk something
