They go brrrrr

[raw kettle]

what if you shoot at a position based on target velocity X ms into the future factoring in velocity of the bullets?

[cedar gate]

thats the next step.

• getting the aim point from perceivable comp to not shoot at the feet

[raw kettle]

true, alternatively bounding box center

[cedar gate]

ohh true

[raw kettle]

vector.Lerp(mins, maxs, 0.5)

[cedar gate]

vanilla prefabs all have the first aim point in the center. But cant use that for other mods

[raw kettle]

maybe perceivable component is the way to go as you could make it ignore everything that is not perceivable?

[cedar gate]

so bounding box is a good option

[raw kettle]

but doing FindComponent when seeking targets is not what I would call efficient 😦

[cedar gate]

only need to do that once for new targets

[raw kettle]

maybe better off modding character and vehicle class and just doing some init where you'd store all the potential targeting information

[cedar gate]

I guess bounding box center is a good start

[raw kettle]

in any case excited to see this progress because aircraft pilots need a reminder how fragile aircraft is

once you get the prediction working maybe it could shoot down RPG rockets hehe

[rough elbow]

had my volume down when first playing this video and it sounded super farty

[cedar gate]

same sound as the big turret :p

[raw kettle]

use it to shoot down projectiles fired by my bomber zombies

I wonder if those blobs would even collide with bullets, or rockets in general

rockets have colliders I think so maybe

idk if this is even something you'd be interested in but if it helps inside bacon photo props there is an emitter that fires slow moving rpg7 rockets

[cedar gate]

Here with the ak sound file 😄

[cedar gate]

Its on the list

[cedar gate]

ill just shoot counter rockets

[raw kettle]

iron dome

[cedar gate]

Bounding box center ✅

[raw kettle]

looks great so far

so for predicting path you'd do something like aimPosition = targetPosition + (targetVelocity * distance/projectileSpeed)?

for a shitty leading implementation

[proper saddle]

In warno I used a CIWS system against zombies

[proper saddle]

Bro got turned to red mist 😭

[raw kettle]

is this 100% scripting or is it AI driven?

I'm wondering if making this an AI agent you could access AI ballistic tables and use the aiming features that have leading built in

[proper saddle]

Somebody used AI before but it didn’t work too well

It had a low range and was extremely inaccurate

[raw kettle]

you probably mean something like an AI gunner inside the turret which is irrelevant

I mean making the turret entity itself an AI agent

[proper saddle]

Oh

Maybe idk

I can’t remember

I just know they used some sort of AI and it kind of sucked

[raw kettle]

it makes sense as AI characters in turrets is useless a lot of the time, but is not really related to what I am thinking about

[proper saddle]

I’m just confused on what difference it would make

[raw kettle]

other than it being completely different?

[proper saddle]

Would it not still be inaccurate?

(I don’t understand enfusion ai)

[raw kettle]

dont compare it to a character using a turret

your own AI agent can work the way you want it to work

[cedar gate]

100% black magic with math

no ai

[raw kettle]

I honestly dont think the effort on making this an AI agent is worth it

the chances of it being perfect vs useless are equally high

[cedar gate]

true

and with scripting you have 100% control

[raw kettle]

but through access to AI ballistic tables and aiming you can swap out munitions and it would Just Work™️

[cedar gate]

i can do that

[raw kettle]

otherwise I am not sure you can get the projectile velocity of the loaded round in script?

[cedar gate]

check the BallisticTable class

op

[proper saddle]

I see what he means

[cedar gate]

thats what the ai also uses to aim

[raw kettle]

oh ok great that should be sufficient

however this does not have leading so you'll have to add it on top

[cedar gate]

that what i use to include ballistics but not lead

exactly

[raw kettle]

maybe you could do something like save time to 1000 meters in init and then you could use it to compute velocity for leading for every munition

idk

[proper saddle]

You also could* script in inaccuracy chance

[raw kettle]

no, you dont

[proper saddle]

You don’t?

[raw kettle]

I mean you can if you want, but you'd usually add some randomness to each bullet being fired anyway

[proper saddle]

Oh okay

[raw kettle]

otherwise they'd all fly the same trajectory

[proper saddle]

I mean if bon really wanted he could make it 100% accurate I guess lmfao

[cedar gate]

close

[proper saddle]

🫡

[cedar gate]

but thats with just 250 projectile speed

[cedar gate]

Yeah need to do that, no inaccuracy currently just straight aimbot 😄

[proper saddle]

Turn up the projectile speed to 1000

💀

[raw kettle]

dope, whats the formula you ended up using for leading?

[cedar gate]

this ^^

ez inaccuracy

[raw kettle]

really it was that simple?

[cedar gate]

idk I just used it and it kinda worked

[raw kettle]

maybe im not as bad at math as I think I am

[cedar gate]

I set projectilespeed to 250 to test but the longer you shoot the leading breaks

[raw kettle]

only when objects move away from the shooter?

I think air resistance might be screwing up my shitty formula

the bullet slows down over longer distances

the good news is at 1000m/s you might be able to be accurate at 4x the current distance

[cedar gate]

using a random tracer round with 890.000 init speed

[raw kettle]

this looks like the code still thinking its 250

[cedar gate]

i hardcoded that

[raw kettle]

this with hardcoded 890 then?

[cedar gate]

when it breaks or slows down it is wrong hmm

[raw kettle]

making me want to try this but I'd have to invent the turret first

[cedar gate]

will make it public soon ^^

[raw kettle]

neat, I'd be interested in seeing debug shapes of target position, aiming position, and target velocity

stuff like that haha

I wanted to do this eventually anyways

how do you determine if its ready to fire? dot product or something?

[cedar gate]

im lerping to the target pos and if lerp is 1 go brrr

[raw kettle]

I think projectileSpeed or whatever needs to be smarter in the equation to factor in bullet drop over the distance and stuff

since distance to target of a round is not linear with air resistance

like the time doesnt scale linearly with distance

or rounds with no air resistance lol

[cedar gate]

just tried that but same problem

[raw kettle]

well precomputed ballistic table might still be using values computed with it

[cedar gate]

Looks like with lower DTime is hits better

I tired different update times, frame and physics

[raw kettle]

make the spread big enough to hit it eventually

[cedar gate]

Hmmmm

Green is bounding box center and blue is aim point

[cedar gate]

fair

[raw kettle]

bounding box is not up to date on where the model is?

wat

[cedar gate]

on normal dtime yea

[raw kettle]

does aiming use EOnFrame?

I'm not sure if the misplaced bounding box/model stuff is the problem here though

[cedar gate]

its a system

i tried frame and simulate physics, post sim phyiscs and after physics

[raw kettle]

wut

I hope this is just a glitch of the time setting

[cedar gate]

wait i changed it in the config but my script always does frame

[raw kettle]

interesting that it aims well in slowed simulation but not real time

I hope you are not being arma'd

[cedar gate]

Whats the point of the system points if you have to hardcode the time anyway ._.

[raw kettle]

idk I barely use Systems

no inheritance lol

miss me with that

[cedar gate]

in the system script you set the timeslice anyway
float timeSlice = GetWorld().GetPhysicsTimeSlice();

[raw kettle]

bc it doesnt give it to you like timeSlice on entity or component?

[cedar gate]

yea

[raw kettle]

I think I read somewhere that it is planned to have a way to define how often they iterate

but not implemented yet

but no inheritance for systems classes kills it for me

have object oriented language but u cant use it here because reasons

[cedar gate]

idk what I did but with physicstime it spawn 100000000 projectiles, crashed my game and wont open WB anymore 💀

I got arma'd

[raw kettle]

was fun while it lasted

[cedar gate]

yea

next project

[raw kettle]

rest in pepperoni

[cedar gate]

nvm whole WB is broken. Next game gg

[proper saddle]

So how’s it going

[raw kettle]

so how did u do target detection? just iterate over an array of all editable characters/vehicles?

or tag system

[cedar gate]

sphere cast

[raw kettle]

oh my

[ionic stag]

how large of a radius?

[cedar gate]

depends on what you set in the turret

[cedar gate]

looks like bounding box is just lagging behind

origin + aimpoint it is

perfect leading with origin
Bounding box is probably set every frame

[raw kettle]

Get bounding box center once and add to origin as offset?

[cedar gate]

but if its exactly on the frame where to bounding box is offset?

[raw kettle]

Tbh bounding box might change too

😦

[cedar gate]

and if I add offset might aswell use aimpoint

[raw kettle]

Yeah

[proper saddle]

How goes it

[cedar gate]

yes

[proper saddle]

yes….?

[cedar gate]

it do be going

[proper saddle]

Can’t wait to see bon

[cedar gate]

Not sure if the bullets actually collide with the rocket

[raw kettle]

darn it wouldve been cool if they did

[cedar gate]

I could fake it and just explode the rocket after 1 sec of shooting at it :p

[raw kettle]

might have to since collisions would be not in sync anyway probably

[cedar gate]

yea that would be a nightmare to calculate the collision at these speeds

[rough elbow]

You could try adding one of the SCR_DamageManager components to the rocket

otherwise it might just be missing the collider it needs

yeah missing a FireGeo

[proper saddle]

You should make it shoot down the RHS cruise missile and f18 bombs

[raw kettle]

I don't think using physics collision to shoot down rockets is a good idea because it will desync

[proper saddle]

True

You could use a invisible collider beam instead of making each bullet have to collide

If that makes sense

[cedar gate]

Looks real

[raw kettle]

hows it look in multiplayer?

[cedar gate]

not mp ready yet. need to code all that in first

brrrrrrr

[raw kettle]

nani

h-hes fast

are you still using sphere query? can I ask whats the performance like when you put this in a town or next to a forest?

[cedar gate]

It does eat like 60fps every query in a town 💀

[raw kettle]

on the upside it will prevent people from firing at you when you are next to it because it will take them 5 hours to aim with 1 fps

[cedar gate]

rip xbox ppl

[raw kettle]

ah no nevermind it would eat server fps only

[cedar gate]

but that lags players aswell

[raw kettle]

yeah ping becomes like 1000

[cedar gate]

Soo time to rework the targeting without spherecast

Im never gonna target buildings and trees / static stuff anyway

[raw kettle]

the way I "solved" it for my VTOL HUD was to iterate over all editable vehicles instead of doing a trace, but I don't have a good solution for finding projectiles.

@ruby turtle did you figure out your projectile detection stuff and could you possibly share how you ended up doing it?

[cedar gate]

I could override some comp on a missle and keep a list with all active ones

[cedar gate]

Actually yeah super simple, just new comp tracking every projectile if its shot

[ruby turtle]

ye i use tagsystem to search for playerEntities or nades near the spawns, if player i subscribe to all SCR_MuzzleEffectComponent.OnFired event of all its weapons and just delete projectile when invoked (client side its looks like it doesnt work but server side it does)

[cedar gate]

No more -60fps

Now with EditableEntity and custom projectile tracking

[raw kettle]

[proper saddle]

Bacon why does your m4 have a hen### skin 💀

[raw kettle]

1. wrong thread
2. spam ping pls dial them down a bit

[proper saddle]

I’ll turn off ping but I replied once wdym spam want me to ask in your mod post then?

[raw kettle]

that'd be more on topic yeah

[cedar gate]

yeah this is my thread ._.

normal projectiles dont have rpl comp hmmmmmmmmm

[proper saddle]

Do you have your own showcase thread?

[raw kettle]

no they dont and if you add it then everyone sees duplicate projectiles

[proper saddle]

That’s weird

[cedar gate]

you are in it

for all mods no

[proper saddle]

Idk if this counts

I mean like in enf showcase lol

[cedar gate]

Maybe rplprop the target ent, and shoot clientside? except rockets cause they have rpl comp

aiming signals are replicated anyway

[cedar gate]

mp is ready, I just forgot LoS. Hopefully raycasts are not that expensive

[raw kettle]

you can run them every second frame or so it should be sufficient

[cedar gate]

[raw kettle]

sweet

[hasty solstice]

Can be spawned with GM? Can't find it

[cedar gate]

yea us and ussr. Search doesnt work , need to scroll a little to find it

[cedar gate]

But looks it its not working ingame but peer tool worked

[cedar gate]

Fixed now 🙂

[honest prawn]

.

[hasty solstice]

I think something is not working

[cedar gate]

Looks like aiming is offset a little. So weird, cause its working find in WB + peer tool

Will look into it, thanks for testing

[hasty solstice]

The videos are singleplayer, I can try to ask a friend test it on a dedicated server

Does it have a minimum detection distance?

It seems that whenever there is a helicopter on the map with an enemy entity inside, it automatically detects it and starts firing, with no line of sight or distance limit apparently

[cedar gate]

3600m

should only fire with LoS tho

[hasty solstice]

In the first video you can see that it starts shooting without line of sight

[proper saddle]

In the video it started firing as soon as he placed an ai through it and there were multiple trees in between

[cedar gate]

LoS is fixed but not sure why it shoots in the wrong direction on dedicated

[honest prawn]

Someone else had a cwis before and it did the same thing, the way you had to fix t was place it, take off and fly close enough to where it starts shooting, then go into GM and turn it until it hits the helicopter, then it would aim properly, but not always

[raw kettle]

I think it was done differently

[cedar gate]

It cause I didnt factor in the turrets current rotation

I forgor to test with a rotated one

[cedar gate]

✅

[raw kettle]

will help with turrets that go on the bottom of a ship hull etc

[ocean bane]

How were you able to get these projectiles? Is that in editor only?

[raw kettle]

those look like debug line visualizations

[cedar gate]

Normal tracer ammo

or the rockets it shoots down? I just spawned them to test

[ocean bane]

The rockets. That was pretty cool🙌

I’m wondering now if it’s at all possible to turn those rockets into a placeable gm item so that the CWIS can have a larger threat to deal with.

[cedar gate]

Not tested but you can try https://reforger.armaplatform.com/workshop/5994AD5A9F33BE57-GameMasterFX

[ocean bane]

Tried and it doesn’t sense them☝️😔

[cedar gate]

target finding is a bit bugged rn

[ocean bane]

All good. Mod’s great though🙌

[cedar gate]

Latest updates are on my discord (link in profile) ^^

[ocean bane]

🤙

[raw kettle]

game master fx has shells not rockets so prob not idk

does it differentiate between rockets fired by friendlies or not?

[ocean bane]

No. It does not.

[raw kettle]

so if I fire an RPG close by to the turret chances are it'll mow me down? sign me up

[ocean bane]

🗣️‼️

[cedar gate]

It targets anything based n ammo_rocket_Base

[ionic stag]

Is there a way to get the parent/entity the projectile was fired from? Then check if that entity’s faction is the same as the faction of the CIWS?

Don’t know how much overhead that would add if you only check each valid projectiles faction

[cedar gate]

technically yes
