Don't make a 2D game out of UI elements 🥺

[chilly nymph]

I'm making a ton of menus.

There's reasons I'm pooling.

Isn't this an advanced channel? 😄

[sly grove]

Yes. Sometimes people think it's a good idea to make things like card games purely out of UI elements though

[gentle topaz]

Just don't understand the value of saying "Would be crazy of I was making a 2D game" as if that meant anything. What does making a 2D game have to do with UI? There can be 2D games with almost no UI, and 3D games with tons of UI.

It is also possible to have conversations without sounding entitled and sarcastic. Usually gets your question answered faster.

[chilly nymph]

Because you're assuming I am making a game without UI?

[chilly nymph]

And it's also possible to answer a direct question as opposed to sounding like you know anything I'm creating and assuming I'm wrong because I'm pooling UI. Not only is that arrogant it's also not helpful.

We're in Advanced chat are we not? Why do you automatically assume people don't know what they are doing? Is that a insecurity about your own skills?

[hard lily]

My game has UI but does not use Unity's UI system

[chilly nymph]

My entire game is UI.

[hard lily]

Have you read this? https://unity.com/pt/how-to/unity-ui-optimization-tips

People often pool UI objects by reparenting and then disabling them, which causes unnecessary dirtying.

Solution: Disable the object first, then reparent it into the pool.

You will dirty the old hierarchy once, but once you reparent it, you’ll avoid dirtying the old hierarchy a second time – and you won’t dirty the new hierarchy at all. If you’re removing an object from the pool, reparent it first, update your data, and then enable it.```

That article has a lot of useful tips on the matter

[chilly nymph]

Yes I'm aware of that thank you.

Class A (which I made) won't recognise class C (a Unity class) but class B (which I didn't make) can, even though A and B both use the namespace that C is part of. Why could this be happening?
I've heard it might be something to do with assembly definitions, but I don't know enough about that to actually figure out a solution.

[gentle topaz]

Well if your code is in a custom assembly (even if it was an accident), you would need to reference the Unity assembly that contains class C. This is probably what class B did.

Hard to give a definitive answer with so little information.

[wet burrow]

yeah sorry I can't show my code or anything, this is for professional work and I'm under an NDA

[wet burrow]

How would the class reference the appropriate assembly? Maybe there's some syntax in class B that I haven't noticed?
e.g. the syntax used

[flint sage]

No it's a separate file

[gentle topaz]

If assembly definitions are present, it has nothing to do with the code itself.

[flint sage]

Anyways, read the docs to figure out how they work and see if you have any

[wet burrow]

@flint sage @gentle topaz so how would I actually figure out which assembly definition a class belongs to? I searched for all the files with the .asmdef extension, but there's a ton of them and none of the names seem to correspond to stuff in the B class

[flint sage]

Asmdefs apply to the folder they're in and sub folders, check your project structure

[wet burrow]

so if I've got this right:
I should look for B and check the folder it's in, to see the assembly definition it's part of.
Then I should either make a new assembly definition for A that has the same references as B, or move A into the same folder as B?

[flint sage]

Something like that yeah

[gentle topaz]

If you didn't make the code for B (as in it's third party), I would go for the first option (or find whatever existing assembly that its part of and add the references there)

[wet burrow]

@flint sage okay I didn't find one in the exact folder, but I backed up two parent folders and found an .asmdef file that seems to be related to that code.

[wet burrow]

B isn't third party, it's part of the same project, but it was created by someone else who's left now (I'm their replacement).

well fuck you then Unity

I opened the asmdef and all the references are arbitrary strings of hexadecimal values, all preceeded by GUID:

[gentle topaz]

You don't want to open it in a text editor..

It has an inspector where you can configure all the references and build targets

[wet burrow]

@gentle topaz okay I think I found the file in the editor and opened it in the inspector

back in 5 mins

Hey guys, i did a code to add items to inventory, it has a system to handle the maxstack per item, for example HP Potions maxStack can be 30 and leather can be 500 and equipments 1.
I have a problem because when the bag is almost full the game breaks for a second to do the code, cause of the complexity i've done it.
Anyone knows how can i optimize this?

public void Add(Item item,int nItems){
        int rest = nItems;
        if(Items.Find(i => i.id==item.id && i.qnt < i.maxStack)!= null){
            foreach(Item i in Items){
                if(i.id == item.id && i.qnt < i.maxStack && rest > 0){
                    if(i.qnt + rest > i.maxStack){
                        rest = i.qnt+rest - i.maxStack;
                        i.qnt = i.maxStack;
                    }else{
                        i.qnt += rest;
                        rest = 0;
                    }
                }
            }
        }
        
        if(rest>0){
            do{
                Item i = item;
                if(rest > i.maxStack){
                    i.qnt = i.maxStack;
                    rest -= i.maxStack;
                }else{
                    i.qnt = rest;
                    rest = 0;
                }
                Items.Add(i);
            }while(rest>0);
        }
    }

[wet burrow]

@gentle topaz okay so I wasn't able to figure out exactly what I needed, but I copied and renamed that existing assembly definition, and now the reference seems to work?

@gentle topaz thanks

Hello trying to deserialize null to default value for value type variables, is there any easy way to do so with Newtonsoft (I am not sure if i am on right way but tying to find answer here > https://www.newtonsoft.com/json/help/html/NullValueHandlingIgnore.htm < )

I dont like this 2 solution

trying to find better one

[novel plinth]

Value types cant be null unless they're nullable value types

[heavy juniper]

Hey guys, I am trying to get collision surface normal (normal vector) to fire explosion in that direction. I am using onCollisionEnter(Collision col) to get collision normal via col.GetContacts(0).normal, however when I draw the ray in Scene view the normals are completely off, always pointing in forward direction (slightly randomly).
Surfaces the capsule hits vary (some are planes, some are triangle-segmented spheres etc.). At the end of the day it always hits the flat surface, therefore there should be no problem with normals. Any help would be appreciated 🙂 (an example below is how I imagined it to be)...sorry for spamming, was not sure whether this belongs in #archived-code-general or #archived-code-advanced

[fresh salmon]

Can you post the code where you draw the normal for debug? Depending on the method there are small differences to the arguments you need to pass.

Normals were always accurate for me, so I suspect the issue is on the debug draw

Also don't cross-post

[heavy juniper]

deleted the post in #archived-code-general

[wise bobcat]

hello

I really need help with something
and i am asking it for like 2 days

[heavy juniper]

@fresh salmon void Explode(Collision collision) { Quaternion ExplosionRotation = Quaternion.FromToRotation(Vector3.forward, collision.GetContact(0).normal); Debug.DrawRay(transform.position, collision.GetContact(0).normal*100f, Color.red, 10f); GameObject explosion = Instantiate(Explosion, transform.position, ExplosionRotation); explosion.GetComponent<Explosion>().IsOpponent = IsOpponent; Destroy(gameObject); }

I save the collision from onCollisionEnter() and pass it in Explode()

[fresh salmon]

Alright gotta check the docs one sec

[dense pond]

collision.GetContact(0).normal is different from the surface normal

probably use a raycast or something to get the surface normal

[fresh salmon]

And transform.position as the origin point of the debug ray seems wrong

Surely you would pass the hit point in there

[deep scaffold]

thats the whole point why i am trying to deserialize json to default value and not null

[heavy juniper]

This is the Grenade gameObject with Explode() function rather than Explosion gameObject with Explode(). transform.position gives the correct coordinates of explosion, no issue there.

[heavy juniper]

Oh, is that so? 😮 Hmmm ..However, I do not have collider/rigidbody on the surface it hits, I only have a layer. I assume that will be an issue.

What is the most convential way of getting the surface normal upon collision? Is RayCastHit the only way?

[fresh salmon]

I wonder how you get your Collision parameter then

Because you usually get that from OnCollisionEnter, and without a collider on both surfaces OnCollisionEnter doesn't run

[heavy juniper]

So this is a grenade that sticks to the surface and explodes. I have Update() in which I have a coroutine that regulates when it's the time to trigger Explode(Collision collision). I also have OnCollisionEnter(Collision collision) in which I get collision, it is saved as protected Collision collision globally in the Grenade.cs file.

this is all the logic

[fresh salmon]

Yeah, but

I do not have collider/Rigidbody on the surface it hits
With this information, I'm pretty sure your OnCollisionEnter never runs

[heavy juniper]

Mhm, there was a mistake on my end. There is a Mesh Collider. 😄

[fresh salmon]

Ah alright

[heavy juniper]

This is the dome the player on that podium can hit. The grenade sticks to the surface (becoming Kinematic when onCollisionEnter() is triggered)

[fresh salmon]

Can you try:

Quaternion explosionRotation = Quaternion.LookRotation(collision.GetContact(0).normal);

For the rotation calculation? This assumes the local Z axis of the explosion prefab points outwards, ie. the particles of the explosion go towards their Z axis

[heavy juniper]

Correct, for the rotation. I am looking for the rotation essentially with the normal. I will try it now. Thank you

[regal olive]

Ask the question

[wise bobcat]

nothing i just fixed the problem right a few seconds ago

thx for the reply

[regal olive]

lol alr

[heavy juniper]

The explosions explode in different directions, less consistent than before.

Could the rotation of the projectile (i.e. grenade) hinder the normal vector?

Or does the Collision collision parameter in callback OnCollisionEnter() account for the angle in which it came in? Maybe that scuffs the normal?

[fresh salmon]

Nah it should stay consistent whatever the angle of the object is, if you didn't do that yet can you try setting the Rigidbody's collision detection mode to "Continuous Dynamic"?

[heavy juniper]

Surface or grenade projectile or both?

[fresh salmon]

Itll put more load on the physics engine, but you can't get collisions that are more accurate than this

Grenade, as it's the one with a Rigidbody

[heavy juniper]

Already on Continuos Dynamic.

[fresh salmon]

I'm out of ideas then...

[fresh salmon]

Looks good to me

[heavy juniper]

Ironically, it never rotates correctly exactly, so there must be a major flaw. Could be that some colliders are not that well interactable with each other (i.e. Mesh and Capsule collider)?

...this is how it happens usually

where e = actual explosion direction

sometimes it hits ok, sometimes like this..it's like a Russian roulette 😄

The worst case scenario I will have to switch to radial explosions but that would be a defeat on my end

[heavy juniper]

@trail cloak Which unity version do you have

[trail cloak]

2021.3.6f1

LTS

        public static T PrepareBufferedPannel<T>(GameObject pannelParent, Action<T> preInitializeCallback = null) where T : UIPannelBase
        {
            T pannelInstance;
            if (Instance.m_BufferedPannel.TryGetValue(pannelParent, out var pannelInstanceSrc))
            {
                pannelInstance = (T)pannelInstanceSrc;
                var parent = ActivePannelTransform.Peek().Root;
                //Debug.LogError("Get Pannl To Transform: " + parent.name, parent);
                pannelInstance.transform.SetParent(parent);

                if (Instance.m_BufferedPannelRectTransform.TryGetValue(pannelParent, out var data))
                {
                    data.ToRectTransform((RectTransform)pannelInstance.transform);
                    Instance.m_BufferedPannelRectTransform.Remove(pannelParent);
                }
                pannelInstance.gameObject.SetActive(true);
            }
            else
            {
                pannelInstance = GenerateBufferedPannel(pannelParent, preInitializeCallback);
            }
            return pannelInstance;
        }

pannelInstance.transform.SetParent(parent);

This line is where the issue happens

However this method is widely used under different scenarios, and I failed on finding any useful information about it.

[heavy juniper]

This particular error is versioning error of Unity

[trail cloak]

versioning error??

May I have a more detailed definition on this word? (I'm non-native speaker

[heavy juniper]

It happens due to limitations sometimes on particular version, however the odds are it could be something else

[high karma]

As in that the error only shows on that version.

[heavy juniper]

Correct

[trail cloak]

I see... I'm going to upgrade/downgrade the project and try again

[heavy juniper]

How long have you been using this version, has the version gotten any updates?

[trail cloak]

This is an LTS version... which been released recently

[heavy juniper]

Did you edit the any of the source projects files by any chance..changing guid or something

[trail cloak]

No I didn't

Just saw a new version (2021.3.7f1)

[heavy juniper]

did it run ok before on this version

if it was released recently, it could have gotten a patch by developers that caused the bug

@trail cloak Another thing, try looking in Package Manager for any errors (instead of a green tick, it will have a yellow sign or red stop sign)

@trail cloak wait, wait...

you have a stacktrace error 😄

One of the parents or children is null

[trail cloak]

But.... a null reference parent can crash the unity sounds...

weird

[heavy juniper]

var parent = null I assume

Check for nullity with if

[trail cloak]

I will try to log it

[heavy juniper]

Check if ActivePannelTransform is empty

because you do not seem to get the root/parent

SetParent() probably does not accept null values is my guess

[trail cloak]

wait.... it stops crashing after I added the check

[heavy juniper]

obviously, but the question still remains

[heavy juniper]

Why is ActivePannelTransform null or empty? Where do you get it

[trail cloak]

Correction, not the check, I added the log

[heavy juniper]

Hmmm

[trail cloak]

may be I should remove this line and try again

[heavy juniper]

if it works, you have a caching issue

LogError logs into error stream, thus ignored but packed in the error in Console I assume

[trail cloak]

And.... it crashes after I remove the log line

[heavy juniper]

Yes, try to find out why is parent == null ,that is why is ActivePannelTransform not returning you the parent.

[trail cloak]

I see, but a SetParent(null) can crash the Unity....

I should open a new project and test it

[heavy juniper]

Sure

Try downgrading the unity version

and if so (issue is gone with the downgraded version), report it to Unity hub forums as others may encounter the same issue, should prioritize the potential fix

[trail cloak]

Anyway thx for the help

[heavy juniper]

Hope it works out for you

[undone coral]

what is the purpose of this code? to pool ui elements?

[tiny lotus]

Hi there, we collaborate with a team that told us the following:
When rescaling in Unity, Unity has to do an operation every frame for every asset that is rescaled. On top of that, if the rescaling is non linear (Height is 0.6 and width is 0.8, for example), then unity has to do ANOTHER operation every frame. So, optimization-wise, since we'll be targeting mobile, it would be best to scale assets in maya.

I did not find any information concerning this performance optimization on the Unity documentation. Someone can confirm that (or not)?

[flint sage]

I mean I guess it's technically correct but it's a matrix multiplication based on the transform values, it'll be executed either way afaik

[tiny lotus]

mmm that makes sense ^^, thanks 🙂

[rugged radish]

that is true
in early days of my prototype I declared a scale const that was applied to every object in the game upon instantiation
when I found the scale I wanted I removed the scaling const and performance increased significantly

[tender light]

Thats mind blowing actually. Hmm. I wonder if this also dirties the object hierarchy. That would be a huge problem.

[rugged radish]

no idea about that, but when every object in the scene has a non-one scale it can reduce fps by 2 or 3 times, depending on the object count ofc

[tender light]

I presume this is not just a editor thing but also applies to builds?

[rugged radish]

personally, never tested in built versions, discovered it randomly and didn't occur to me to see how it works in a build

should be pretty easy to test

[tiny lotus]

Ok 🙂 but how do you deal with scattering on environment in that case? You re-scale all your maya object and create different model for the same "rock" for example but with different size?

[rugged radish]

all my assets are programmer art, but for one of the experiments I had to bake maps at one scale and export the model at a much smaller scale
I'm not sure if that was the question, I'm have very little knowledge regarding asset workflow

[tender light]

I think he asked: how do you then create varied environments if you cannot for example randomize the scale of your trees 0.8-1.2 etc...

[rugged radish]

oh, I will have to research that myself at some point
I remember reading about render optimizations and one of them mentioned a more efficient way of applying random variations to some of the object properties, including scale

DrawMeshInstanced for example, uses standard 4x4 TRS matrices
and I already use it for some environment objects
but I never tested how a non-one scale in that call affects performance because everything has a scale of one

varying properties is one of the todo items for me

[tiny lotus]

I do some benchmark with instantiate items with a scale of 1 and other with random scale and there is no different at all ... :/

[rugged radish]

Just tried myself and I can no longer reproduce it
I googled just to check what's the deal here and found a bunch of pages saying the same thing - scaling does affect performance. I guess it depends on the render pipeline and / or unity version.

I started my project in built-in, but transitioned to URP later

in built-in it gad a huge impact, now there's no impact at all

[somber grotto]

how do i detect how much a number variable is changing in a second on average from the past 10 seconds?

[sly grove]

divide the total change over the last 10 seconds by 10

[somber grotto]

yeah, but how do i actively keep track of what the value was 10 seconds ago for every second and compare that?

[undone coral]

you can use unirx to express this succinctly

you would still need to know the name of the thing you are talking about

[fresh salmon]

Just use a coroutine

That adds the value to a collection

[undone coral]

unfortunately unirx does not implement Window.

[somber grotto]

the problem is that i want the value to be updated every second

[fresh salmon]

Coroutine with loop in it

[somber grotto]

so every second it would detect what the value was 10 seconds ago and see what it is now

how do i store what it was 10 seconds ago all the time without making a huge spaghetti

[fresh salmon]

Maybe a queue would be better here

[undone coral]

doing it this way means the user has to operate a circular buffer, which imo is just as hard

you can't dodge the hard problem here

[undone coral]

there are no shortcuts here

[fresh salmon]

So, simple or overkill way?

[undone coral]

there's no simple way. the simplest would be if unirx implemented Window

it doesn't. so you can implement window yourself using Scan, which is too much of a brain explosion

compared to doing it in a loop

[somber grotto]

i guess i could make a list of 10 values, then have it set to a value every second and loop back

[undone coral]

the name of that datastructure is called a circular buffer, but that's only 1 part of the problem

there are 3 more - how to have something happen "every second", how to calculate the average (easy), and then how to emit the average "every second"

[fresh salmon]

while (true)
{
    queue.Enqueue(newValue);
    var tenSecsAgo = queue.Dequeue();
    yield return new WaitForSeconds(10);
}

There

[undone coral]

here's an example of how i do it to average a value (in this case, a vehicle speed) over the last 360 frames (m_BufferSize)

[somber grotto]

what is "queue" referencing?

[fresh salmon]

A Queue<T> instance

[undone coral]

you can find an implementation of CircularBuffer online

[fresh salmon]

Which is a collection that is FIFO (first in first out)

[undone coral]

instead of Observable.FixedUpdate you have Observable.Interval(TimeSpan.FromSeconds(1))

the reason this method is good is that it solves two hard problems - how ot have something happen every second, or if that isn't good you can do something else, and how to emit the value "at the right time"

i don't know what to tell you, it's this hard

there are no shortcuts

you can of course implement all these things directly

• a circular buffer
• something that makes a measurement every second
• something that calculates the average
• something that "emits" the calculated average every second

you can do a circular buffer with a queue

you can do a measurement every second with a coroutine

you can calculate the average in a coroutine

[somber grotto]

yeah that makes sense, i thought of something pretty simple actually and i'm going to try that

[undone coral]

you can emit the average... uh oh, that one is tricky. surely you want to know when the average changes, you don't want it to stairstep

[undone coral]

hmm... not likely to be the right answer if it's "simple"

define "simple"

maybe say it here first

[somber grotto]

yep, but i feel like it might be good enough

[undone coral]

hmm

well what is the objective? why do you need this measurement?

[somber grotto]

basically i'm just making a list and having it cycle through and assign a value to each spot and loop it, then just see what the value was 10 spots ago

[undone coral]

i mean gameplay wise

[somber grotto]

just a silly little idler :P

the problem is that my idler contains randomly spawned objects that have a bunch of randomness involved and they can be chosen to be collected/not collected, so no way to calculate it from just the spawns

[undone coral]

what are you taking the average of?

[somber grotto]

the objective is to get the money value and see how much it increases every second

[undone coral]

okay

[somber grotto]

just sounds like a simple MpS counter at first, but it's more complicated this time :P

[undone coral]

well a moving average is a pretty typical thing to do, and has a very fixed meaning

i don't know if it's something that is often surfaced in idler games

the thing i wrote is indeed a moving average

with a window size (see, there's that word window again) of 360 (really m_BufferSize) frames

[somber grotto]

pretty much all idle games have this, but the vast majority have the income be a static value of income per second so that's very easy to calculate, they're not actually looking into the value and seeing how much it has changed

[undone coral]

Observable.Interval(TimeSpan.FromSeconds(1f))
  .Select(_ => GameController.instance.Money)
        // this is a tuple
  // scan means, do something every second, and hold onto some
  // state (in this case, the buffer) that we can revisit later
  .Scan((window: new CircularBuffer<float>(10 /*seconds*/), average: 0f), (state, value) =>  {
    var (window, _) = state;
    // circular buffer pushback means
    // the oldest item gets popped off
    // when the newest item is added and you are at capacity
    window.PushBack(value);
                   // the average
           // this is a tuple
                    // this measures the average in the buffer
    return (window, window.Sum() / window.Size);
  })

[somber grotto]

yeah i see, i understand pretty much none of it since i haven't dabbled in more complicated code, haven't ever needed to

[undone coral]

that's as succinct as it can get

well

[somber grotto]

so i'll try out my method first and see if i can get it to work

[undone coral]

hmm

well i think you'll figure it out

@somber grotto well i annotated it for you so that it might make more sense

[somber grotto]

okie, i'll have a look in case my method doesn't work :)

[fresh salmon]

New version

while (true)
{
    _queue.Enqueue(newValue);
    if (_queue.Count > 10)
        _queue.Dequeue();
    
    _average = _queue.Sum() / _queue.Count;
    yield return new WaitForSeconds(1);
}

[undone coral]

^this is pretty close

@somber grotto does that snippet make sense to you?

[somber grotto]

i haven't done anything with queues so not really

[fresh salmon]

Think of a queue as a real queue of people

You add people at the end of the queue, and you pick people from the start of it

It's the same for C#, but it's for values instead of people

Enqueue adds a value at the end of the queue
Dequeue removes a value from its start, "sliding the other values forward"

[somber grotto]

oh that's exactly what i'm trying to emulate with a list instead 😄

this runs every second on what i have

but yeah imma try out what you wrote

[somber grotto]

cool it works for getting an average, now just need to do the other stuff :P

@fresh salmon how do i pull values from the queue? like with lists you do list[2]

nvm i just do .First() and .Last()

[sly grove]

typically you should only be using Peek() and Dequeue()

[somber grotto]

oh i mean like, looking at the values

[sly grove]

foreach or Peek()

[somber grotto]

first and last works, linq helps there

[sly grove]

Indeed, First() might be slower than Peek() though

[somber grotto]

since those are the exact values i'm looking for

ah, okie

i'm not really concerned about speed since i'm running just one of these

[somber grotto]

@fresh salmon this ended up being my code, MoneyMade is basically just Money but it never gets subtracted from, this way when you buy upgrades the money per second counter doesn't go negative

[fresh salmon]

Nice, thanks for the update!

[edgy stirrup]

Does anyone know what might be wrong with unity ads. I have made all the stuff work in the editor including all the buttons that trigger the adds but when I build it the initialization function does not work. Does anyone have any ideas on what could be causing it? Im pretty sure its nothing got to do with the code itself as the Advertisement.Initialize is a unity function and not written by me and that seems to be the point of failure.

Hello, I'm Efe Şantay, I'm From Turkey, And My Age İs 11. I'm Doing Trajectory Script, On Unity 5.3.2f1. And My Script Works Like That, İf Tennis Ball Game Object Was OnMouseDown, İt Does, Trajectory.SetActive(true). And İf OnMouseUp, Trajectory.SetActive(false). But My Trajectory Code Gets Error. Error Area This And Error Text: Assets/Scripts/Trajectory.cs(36,40): error CS1501: No overload for method Instantiate' takes 2' arguments. And You Can Look My Code Trajectory.

See? The dotsList [i] = Instantiate (dotPrefab, transform.position, transform.position, Quaternion.identity); İs, Gets Error. What Should I Do In The Correct Version Of This Code? Or, What Should I Choose The Corret Version Of Unity? Please, Help Me And Say The Error's Method For Me, Ok?

And You Can Look Error Pictures Too.

Message By Efe Şantay.

[edgy stirrup]

you need to add Quaternion.identity as a third paramater and a vector3 as a secound paramater

[undone coral]

this is on a mobile device right? have you tried running with the debugger attached?

[edgy stirrup]

I get no errors at all I have done a noob thing because I could not figure out how to get the debugger to run on a build so I created a text element to to log the errors to but i didnt get any

[undone coral]

hmm

are you using a macOS + iOS or windows + android device?

it's worth learning how to debug

[edgy stirrup]

widndows + android

[undone coral]

is it a real android device

or an emulated one

[edgy stirrup]

real phone

[undone coral]

interesting

is your phone weird?

did you get it with Weird from the factory?

is it rooted?

[edgy stirrup]

its not rooted i dont think

the builds work but the ads just dont

[undone coral]

well

there's an error somewhere

[edgy stirrup]

most likely

[undone coral]

you have Unity Ads configured for debugging right?

meaning even when you deploy it to your phone

it should still be in a Debug / Devleopment account

not sure what they'd call it

[edgy stirrup]

no i disabled it for the build

[undone coral]

https://docs.unity3d.com/Packages/com.unity.ads@3.4/manual/MonetizationBasicIntegrationUnity.html#testing

okay well

[edgy stirrup]

you mean test mode right?

[undone coral]

you have to have test mode on*

i guess it's not that obvious

[edgy stirrup]

the same thing happens weather i have it on or not tho

[undone coral]

are you sure

[edgy stirrup]

i did disable it for the build

most of the times

[undone coral]

"Note: You must enable test mode before testing ads integration, to avoid getting flagged for fraud."

it should always be enabled

you should be running test mode until you are in the production lane in google play / released to the app store in ios app store

[edgy stirrup]

oof thanks for telling me that i was doing something very risky

im changing it right now

ok so im rebuilding it again with test mode enabled

Another interesting thing is that the void OnInitializationFaild does not fire either because i did put my logger in there and it did not show up

[halcyon schooner]

So I'm trying to override the currently selected button in my UI, but the selected button in the event systems code either seems to be going slow or keeps updating the same button as selected. Is there any easy way to fix this or diagnose it? I'm using the publisher subscriber method to send all of my information, so I'm not sure if the timings are just somehow off or not. I've tried setting the selected button to null as well but it says it's busy when I do that.

The version of Unity I'm using is 2021.3.2f

[edgy stirrup]

by going slow do you mean the game is getting slower or the event is dellayed?

[halcyon schooner]

The event seems delayed.

But I'm triggering the events in the correct order.

[edgy stirrup]

do you have any corutines in there?

[halcyon schooner]

No

[edgy stirrup]

does it slow down over time or is it slow as soon as you start?

[halcyon schooner]

So the event gets called but seems to be canceled out by the currently selected button.

If I click somewhere with my mouse it will deselect it, but it won't work through the code.

Because it says it's "already selecting an object"

[severe trail]

Does anyone have any experience in mesh subtraction and blendshapes?

Trying to transfer a blendshape to a mesh with pieces subtracted

[edgy stirrup]

so its not a problem with events but with the button

[severe trail]

• at runtiem

[edgy stirrup]

does it trigger at all

[halcyon schooner]

The button seems to trigger properly when pressed

[edgy stirrup]

so what is the scenario when it fails

[halcyon schooner]

It triggers the event to switch to another button, but it can't seem to switch buttons, as it is stuck on itself.

[edgy stirrup]

its like it does not deselect properly then

[halcyon schooner]

Seems so, but I can't figure out how to get it to deselect itself before trying to change the selected button.

[edgy stirrup]

Have you looked at the property Interactable in case that mighet get set to false

[halcyon schooner]

I've tried changing the settings on the button, and forcing it through code, but no luck so far.

[edgy stirrup]

there is an alternative way to make your own button component if that is not working for you.

[halcyon schooner]

Hmm

[edgy stirrup]

I can have a look for a link to an article on that its pretty straight forward

[halcyon schooner]

That would be great if I can't get this to work.

[edgy stirrup]

one sec ill have a look

[halcyon schooner]

Maybe the event system is going too slow for the events to trigger one after another, I'll try to convert it to a delayed coroutine real quick.

[edgy stirrup]

I cant find an artical sorry

but that is a good idea corutines do run on another thred

[sly grove]

Coroutines do not run on another thread

[edgy stirrup]

oh

nvm then

https://docs.unity3d.com/2019.1/Documentation/ScriptReference/UI.Button.OnPointerClick.html

thats the thing i was talking about earlier

[halcyon schooner]

The delay worked, so it seems the events didn't want to play nice even though they should have triggered one after the other.

[edgy stirrup]

nice

[halcyon schooner]

Hopefully no one notices a slightly slower inventory. 😅

Thanks for the info too, I'll have to look into it. 🙂

[quartz stratus]

@halcyon schooner lol was just throwing down on UI deselection stuff today

such a pain

ended up yielding until EventSystem.alreadySelecting returned false, before trying to do anything. that worked on my end. https://docs.unity3d.com/Packages/com.unity.ugui@1.0/api/UnityEngine.EventSystems.EventSystem.html

[river musk]

I have a world the size of 5kx5k, I have an image of the world at resolution 1920x1080 at the size of 600x600. I want to place a map marker on this UI map of 600x600 compared to the players position on the world in the 5kx5k area. Who knows how to do this?

[quartz stratus]

You'd determine the bounds of your world and calculate the players position within them. Say they are at coordinates 1374, 4009 in a 5000x5000 world. So you would then translate that position into the 600x600 space. So multiply each coordinate by the fraction 600/5000. Which gives you a new, re-mapped position in the UI map space: 164.88, 481.08. At least, that's how I'd go about tackling this. Good luck.

[river musk]

Don't I have to scale this to the resolution too?

[quartz stratus]

Possibly. I don't fully understand from your original message how the resolution is playing into this. But it seems like it'd pretty straightforward to test and find out. Hopefully.

[river musk]

Also, 164.88, 481.08 is getting set how? localPostion?

[quartz stratus]

This depends on how your UI is structured but probably RectTransform.anchoredPosition.

[river musk]

Well like if a player changes screen resolution from 1920 x1080 to something like 900x600 I'd imagine this effects it

[quartz stratus]

Ahh. I see. If you're using Screen Space - Overlay render mode, you don't need to worry about this (as much). You can probably use the Canvas.scaleFactor property.

Canvas.scaleFactor is a lifesaver.

Assuming your UI has its anchors and pivots set properly to scale along with the Canvas.

Oh and also need a CanvasScaler component on the same GameObject as your Canvas.

Set to scale with screen size

[river musk]

Thank you so much! I did the math right, screen is screen space, so i screwed up on the anchoredPosition, thanks!

[quartz stratus]

Oh, awesome! np

[wet burrow]

When you're setting up in-app purchases using a ConfigurationBuilder, can you have multiple or do you need to just have one? Do you need to add every single product before initialising, or can you do it in stages?
I've got to procedurally generate and add a massive quantity of products (e.g. thousands across different categories) and I'm wondering how/if I should split them up

[somber tendon]

How would you avoid singleton while keeping your script modular?
Example

 public class A : MonoBehaviour
{
    static public A instance;
    ...
    public System.Action<int i> onDoSomething;

    void DoSomething(int x)
    {
        onDoSomething?.Invoke(x);
    }

    public void UpdateSomething(int y)
    {
        Debug.Log(y);
    }
}

public class B : MonoBehaviour
{
    A.instance.onDoSomething += (int x) => ModifySomething(x);
    
    void ModifySomething(int x)
    {
      x += 1;
      A.instance.UpdateSomething(x);
    }
}

In this way, class A doesn't really care if class B exist or not.
But the use of that singleton worries me since I might unintentionally abuse it later in the future

[novel plinth]

Proly you never heard of factory pattern

at the same time, that may not what your game wants... without further context hard to tell

and the concept quite the opposite from one to another

[sly grove]

What's your definition of "modular"?

Also what's the problem with a singleton?

[somber tendon]

Modular in a sense that class A doesnt need to know if another class (B) is even exist or not.
Currently I have no problem with a singleton, but considering that some people consider singleton as evil 😝 , I might want to try to avoid it... if possible...
That said, I found that it perfectly suits my intention

[deep peak]

abusing singletons is the way to finish the game to the deadline

[somber tendon]

Factory pattern, iirc, needs to know class B first for it to be instantiated by the factory class (A), which seems to break the modularity

[wet burrow]

@somber tendon make sure to use singletons when you know there will only need to be one of it ever

Anyone here used the IAP package? Once you initiate a purchase, what would you use to actually initiate whatever the specific purchase does for you? Additionally, how do you ensure a user's purchases are kept between closing and reopening the app? I presume it's stored on a server somewhere? In that case how is it retrieved?

[somber tendon]

or is it better to write like this instead?

public class B : MonoBehaviour
{
    A aInstance;
    void Awake()
    {
      aInstance = FindObjectOfType(A);
      aInstance.onDoSomething += (int x) => ModifySomething(x);
    }
    
    void ModifySomething(int x)
    {
      x += 1;
      aInstance.UpdateSomething(x);
    }
}

[wet burrow]

okay it seems I just use some custom code to determine what the user purchased based on the Product's id

[sly grove]

this is just a slower singleton implementation

[somber tendon]

Yep, but at least it doesnt look like one 😜

[rocky mica]

there is nothing wrong with singletons

[deep peak]

if each new bullet gonna FindObjectOfType your explosion spawner singleton then this will definitely hurt

making one global facade with static access that handles a bunch of singleton components/services is the most cleanest in my opinion

[undone coral]

How would you avoid singleton while keeping your script modular
the unity component system

for example, dependency injection

var bullet = Instantiate(bulletPrefab);
// during a match
bullet.gameManagerComponent = GameManagerComponent.instance;
// when looking at the bullet in the inventory screens
bullet.gameManagerComponent = HomeScreenGameManagerComponent.instance;

👐 people don't like it not because it's bad, but because it's too simple and they're really doing these cathedrals of engineering in order to procrastinate🌈

[rocky mica]

isnt dependency injection just a fancy word for assigning object references in a Unity context?

haha

[somber tendon]

But this make the class that instantiate the bullet needs a bullet class first, thus, make it less modular, it wont run if I dont have bullet class

[rocky mica]

I mean, even if you use interfaces

you will need an implementation at some point

[somber tendon]

I'm not using interface atm

[sly grove]

assigning references as the object is created.

but yeah I think dependency injection is an over-fancy phrase for what the doctor is prescribing

though I've seen people use that phrase for it a lot

[rocky mica]

people are way too afraid of singletons tbf

[undone coral]

yeah

i am sort of making fun of dependency injection

[somber tendon]

Yeah, every time I heard of DI, I imagine it as an overly complex framework

[undone coral]

unity sort of already does it with [RequireComponent(typeof(T))]

[sly grove]

Well I'm used to dealing with "real" DI frameworks like Java's Guice or Spring

[undone coral]

which could in theory just reference a singleton

that is its actual dependency injection framework

[sly grove]

So yeah it seems a little milquetoast

[undone coral]

[RequireComponent(typeof(T))]
class B : MonoBehaviour {}

interface IMySingleton {
 int value { get; }
}

class MySingleton : MonoBehaviour {
 // an actual singleton pattern
}

class T : MonoBehaviour, IMySingleton {
 public int value => MySingleton.instance.value;
}

but why would anyone bother with this? it's very verbose

^that is dependency injection in a nutshell using just unity primitives

it just goes to show you don't need any of that stuff in a bare bones sense*, unity ships with it, because the component model is old

[undone coral]

guice shudder

remember Dagger?

i'm a maniac though... i use vertx with quasar fibers

long ago, when "Project Loom" was just a star in ron pressler's eye, and you could still get venture funding for a java library...

[sly grove]

yep when I was doing Android stuff like 6 years ago and Dalvik couldn't handle Guice for some reason

[undone coral]

"yeah i member"

[sly grove]

I didn't know about Project Loom until now

what is this, goroutines (yes, i.e. Golang) for Java?

oh god "Fibers"?

[undone coral]

lol

[regal olive]

so im wanting to write code that basically detects what website a project is downloaded from, and if its downloaded from anywhere besides the specified websites, it will initiate basically an anti piracy screen (even though its not a paid project, its just supposed to work as an anti reupload measure), i tried looking up a way to do this, but i didnt find anything, and was wondering if anyone here would know how to make something like that

[trail cloak]

Yes, It's a part of my ui pannel framework, based on UGUI

[trail cloak]

And .... it reappears after I rebooting the Unity Editor

You can report how to reproduce the bug. What is the version you using. What is happening when the bug occur, etc.

[trail cloak]

I see

This is the latest LTS version, I didn't expected that to happend

[jolly vine]

Hey everyone! I've created an ocean vertex displacement shader using shader graph, and now Im trying to reference the vertices on the mesh (with the shader material) to make a buoyancy script. However when I reference the vertices, the position of them is set to the default position, without accounting for the shader. Do shaders not modify the properties of the mesh itself, only visually change the object? Is there anyway around this?

[trail cloak]

Shader only visually change the object.

[jolly vine]

dang it

[humble leaf]

You need to run the algorithm in code to calculate the height at a point.

[jolly vine]

Is there anyway around that?

[jolly vine]

ok

[humble leaf]

So if you're doing gerstner wave calculations in shader, do the same ones with the same values in code at runtime to sample the position.

You don't, you run them in tandem.

[trail cloak]

I think you need to write the script for the node...

[jolly vine]

wouldnt it make sense to run the whole shader in code, that way I dont need to run multiple things that do the same thing at once?

[jolly vine]

Makes sense.

So unity has ways of accessing those functions in code?

[austere jewel]

The CPU side will only be running samples where it's needed because it's very expensive to run thousands to millions of operations on the CPU

[jolly vine]

ok

[austere jewel]

the GPU side can do that with ease, but it's extremely expensive to pass that data back to the CPU

[jolly vine]

ok

Am I able to access gradient noise functions with code tho?

[humble leaf]

You can't access nodes from code, no. They're just code themselves.

[jolly vine]

I've only used Mathf.Perlin noise in the past

[jolly vine]

So I have to rewrite the gradient noise function that shadergraph uses

and use the same seed

to find the height of the ocean vetex's

is that correct

[humble leaf]

Yes

[jolly vine]

or does unity have a built in gradient noise function

[humble leaf]

Though,more specifically, the height that is calculated at a specific position.

Nothing to do with vertices at this point.

[jolly vine]

true

Unity doesn't have a accesable gradient noise function that I can use?

I know very very little about how noise fucntions work

[humble leaf]

https://docs.unity3d.com/Packages/com.unity.shadergraph@7.1/manual/Simple-Noise-Node.html

[jolly vine]

Trueee

I forgot about the shadergraph documentation lol

thanks for your help

this should be interesting....

[humble leaf]

Honestly, water is one of those things that it's just easier to get an asset for that also supports bouyancy.

[jolly vine]

yeah

your probably right

[humble leaf]

Let someone who is a master shader dev solve it for you and get on with your project.

[jolly vine]

your right

but I'm poor

and I'm up for the challenge

and I've tried finding water shaders that I like, and work with what I'm making in the past, and its been hell

And I've gotten decently far along making the water so far and it looks good

cant give up now!

Thanks for your support tho guys, I really appreciate it

Unity doesn't make the shadergraph functions public right? So I have to copy and paste all of the code on the shader graph documentation and plug it all into each other?

[viral flicker]

Hey everyone, how do i create a complex combo attack system similar to platinum games in 2d. I have seen tutorial that writes code for playing three different animations in row after input x amount time, but i want to know how to play different animation according to different inputs like for eg pressing x 2 times and y 1 time etc

[jolly vine]

Are you planning on using Unitys animator

[viral flicker]

Yeah, i currently use my own script animation state controller. Dont want to deal with animator web fuckery

[jolly vine]

does anyone know how to access the functions used in the unity shadergraph documentation?

when I copy and paste this float unity_gradientNoise(float2 p) { float2 ip = floor(p); float2 fp = frac(p); float d00 = dot(unity_gradientNoise_dir(ip), fp); float d01 = dot(unity_gradientNoise_dir(ip + float2(0, 1)), fp - float2(0, 1)); float d10 = dot(unity_gradientNoise_dir(ip + float2(1, 0)), fp - float2(1, 0)); float d11 = dot(unity_gradientNoise_dir(ip + float2(1, 1)), fp - float2(1, 1)); fp = fp * fp * fp * (fp * (fp * 6 - 15) + 10); return lerp(lerp(d00, d01, fp.y), lerp(d10, d11, fp.y), fp.x); } into my code

it gives me a whole lotta errors

I added the Unity.Mathmatics namspace, and it fixed some of it

but not all of them

[devout hare]

That's written in HLSL, not C#

[jolly vine]

oh

well thats not very fun is it

I assume I have to just convert it to c# then

[novel plinth]

Shader language has an entirely different concept 🧐

[jolly vine]

ok

[lilac arrow]

hello guys
i want to instantiate 4 objects in the same time randomly and in random position without any repetition
but i have a problem withe the instantiating timing

the 4 squares are spawning so fast and not lined under each other

[heavy juniper]

Does parameter col in OnCollisionEnter(Collision col) give information about the surface it hit (whether it is triangle, cube etc.), something that could help me manually calculate surface normal in any way. As one could imagine, Unity docs are very descriptive.

[humble onyx]

so i assume normal of the contact point is not what you are after?

[heavy juniper]

Contact point normal turns out not to be a surface normal but a normal of the collision, which depends on the angle of the impact.

However, based on collision I could maybe get data about what polygon it hit and its vertices.

That would be helpful for calculating my own surface normal (actual normal)

[humble onyx]

so you would need the surface normal at the nearest point the the impact on the mesh
(keep in mind that collision and visible mesh might not be the same)

[heavy juniper]

Correct, something like this.

It doesnt have to be 100% accurate, error of =0.1% or in range of that would be acceptable

[heavy juniper]

I am aware that sometimes it might select a neighbouring polygon with this approach but the angle difference isnt too big since the dome (object that a player hits from within) is huge.

[humble onyx]

my best guess is to transfrorm the collision point in the space relative to the mesh you want to search over
then find the closes vertex and use the normal of that vextex index

(doing some testing with that)

[heavy juniper]

I should point out that it is a concave mesh.

You are in the dome

Shooting the walls of the dome from within

Its not convex relative to you

[humble onyx]

do you want the normal of the collision mesh or the visible mesh?

[heavy juniper]

Actual mesh, but I would expect them to be the same or am I wrong

Ill sketch, one second

[humble onyx]

A convex mesh collider can only have 255 triangles so it might not match your rendered mesh

[heavy juniper]

Hmm that actually be

Ill check

This is what I am looking for essentialy, an object (capsule) hitting the triangle and getting surface normal of the surface where collision occurred. Red dot is contact point.
I also make it stuck there, so kinematic = true. Could that affect, probably not?

[humble onyx]

I made a small test script that gets the nearest point to a game objects position and gets the normal for that point

using System;
using System.Linq;
using UnityEngine;
public class FindColosestPoint : MonoBehaviour
{
    public MeshFilter Filter;
    // Update is called once per frame
    void Update()
    {
        Vector3 myPos = Filter.transform.InverseTransformPoint(transform.position);
        var lowestValObj = Filter.mesh.vertices
            .Select(x => new { MyObj = x, Value = Vector3.Distance(x,myPos) })
            .OrderBy(x => x.Value)
            .First();
        Vector3 foundPos = lowestValObj.MyObj;
        int index = Array.IndexOf(Filter.mesh.vertices, foundPos);
        Vector3 normal = Filter.mesh.normals[index];
        Vector3 foundPosWorld = Filter.transform.TransformPoint(foundPos);
        Debug.DrawLine(transform.position,foundPosWorld);
        Debug.DrawRay(foundPosWorld,normal,Color.green);
    }
}

it should be easy to adapt that to use the collision point instad

[heavy juniper]

Wow thats awesome👌 thank you, will check it in a bit (currently at the restaurant)

[humble onyx]

Good eating 🙂

[obsidian glade]

does the contact point normal really depend on the angle of impact? in a local sense a collision happens between two points (really, one point shared by two surfaces), any velocity should be irrelevant, and indeed the 2 points should provide a normal to the surface as that is largely what a collision is

[heavy juniper]

In my case it seems as if it does depend. Different angles of projectile (capsule) colliding with the surface is causing different normals. I hopped to conclusion that apparently angle of impact affects the normal, however as you pointed out, it does not make sense.

[obsidian glade]

I wonder if it's an issue with fast moving projectiles & interpolation

[heavy juniper]

That could also be. I am so intrigued to test out the code above but I am the restaurant now...and most likely wont be back to Oculus to try it out until later this evening 😢. Thanks for all suggestions tho!

Hi, İm Errored On ProjectileDragging Code At (45,72) Area, And Code On İn The First Picture Or İn 2022-08-10(1).png.

And Here's Pictures And My Code:

[upbeat path]

Velocity is a Vector3

[regal olive]

can i check the code version?

[upbeat path]

I dont understand your question

[regal olive]

i said the coding Of Velocity is a Vector3, in like This example:
tennisBallPrefab.GetComponent<Rigidbody2D>().velocity = dir * 8; // 8 is multiplier to our force.

[upbeat path]

Sorry, Vector2

you are trying to set it with an int

[regal olive]

oh, let me try, it does or doesn't works, İ Back To You Again.

İ think İt's Worked, And Here's Updated Version Of My Code:
tennisBallPrefab.GetComponent<Rigidbody2D>().velocity = prevVelocity * 8; // 8 is multiplier to our force.

İt's Like That? İf Yes, Ok. İf No, Ok, Let me try Other Version.

[upbeat path]

That's OK

as long as prevVelocity is a Vector2

[regal olive]

ok.

And İm Created New private Vector2 dir; And İm Tried To tennisBallPrefab.GetComponent<Rigidbody2D>().velocity = prevVelocity * 8; // 8 is multiplier to our force. Code, İt Work's Again.

[mint sleet]

    private IResult ThereIsNoMultipleIntegrationManager(string orgNumber)
    {
        _orgAdminUserService.GetAllByOrgId(orgNumber, "", true, true);
    }
``` Is there any way of sending the true and false values at the same time

so it will query both "false" and "true"

[upbeat path]

Do you mean you want one parameter to be both true and false at the same time?

[regal olive]

@upbeat path, İ Have A Error Question On You, (55,50) And (56,33) İt's Gets 3 Errors, 3 Errors Code İs: CS0119, CS1502 And CS1503. Here's My Code And Pictures:

[upbeat path]

The error messages are telling exactly what is wrong and where it is wrong, you need to learn to debug this basic stuff yourself

[wary swift]

Not to gatekeep or anything but I feel like this is more appropriate for #💻┃code-beginner

[upbeat path]

Absolutely

and he should not have pinged me

[regal olive]

ok.

[finite burrow]

Does anyone here have much experience with MoonSharp for Lua?

function Spin(transform, speed)
    transform.rotation = transform.rotation * Quaternion.angleAxis(speed * Time.deltaTime, Vector3.up);
    return transform
end

UserData.RegisterType<Transform>();
UserData.RegisterType<Transform>();
UserData.RegisterType<Vector3>();
UserData.RegisterType<GameObject>();
UserData.RegisterType<Quaternion>();
UserData.RegisterType<Time>();        
DynValue t = ModLoader.Instance.RunModScript("spin.lua", "Spin", new DynValue[]{UserData.Create(this.transform), DynValue.NewNumber(2)});

getting

attempt to index a nil value

I'm under the impression that registering the type is all I need to do for it to contain all it's member data and functions, but because LUA I'm also not sure on which indexer it's failing 😅

[sage radish]

It could be any one of those. If you have debug information about which line it is, you could split it into multiple lines to find the culprit:

function Spin(transform, speed)
    local up = Vector3.up;
    local deltaTime = Time.deltaTime;
    local angleAxis = Quaternion.angleAxis(speed * deltaTime, up);
    local rotation = transform.rotation;
    rotation = rotation * angleAxis;
    transform.rotation = rotation;
    return transform
end

[finite burrow]

Thanks, that's not a bad shout. Just hope it gives me line number errors instead of bytecode indexes

[sage radish]

I assume you are using some capitalization conversion in MoonSharp to use Quaternion.angleAxis instead of Quaternion.AngleAxis?

[finite burrow]

Yeah, everything gets changed to camelCase in MoonSharp

[finite burrow]

Thanks for the help, managed to fix it. It needed the Vector3, Time, Quaternion classes etc. passed to it explicitly

[open yoke]

Hi...I am looking for a way to run a Standalone Linux build of my Unity app in a Docker container on Ubuntu 20.04

I found the GameCI containers but not sure how to deploy my app in it.

Any pointers for the same would be much appreciated!

[undone coral]

what's your objective?

[open yoke]

@undone coral CI/CD essentially. So, start with deploying the Standalone build in a Docker container, run unit and integration tests in Docker and then push to a production container.

[undone coral]

push to a production container?

is this a server backend?

how does it fit into your game i mean

[open yoke]

Sorry, I meant push to production build. No server, its all local

Its a desktop application

Completely self-contained.

[undone coral]

a game?

it's okay if it's not a game

[open yoke]

Its not a game

Just a real-time visualization tool

[undone coral]

okay

and it's meant to run on windows? or linux?

[open yoke]

Linux only

[undone coral]

okay

that's interesting

lol

are you streaming this?

are you trying to do some kind of streaming?

[open yoke]

yes

[undone coral]

okay

do you only need an artisanal quantity of streaming?

like an artisanal number of concurrent users, perhaps for the purposes of a demo

that usually means 1

[open yoke]

Yes

[undone coral]

okay

[open yoke]

exactly, just 1 user

[undone coral]

do you want to stream from a container?

meaning do you want unity standalone to be running inside the container and streaming the video?

[open yoke]

I would be okay to have Unity installed on the Host and simply run the application inside the container

[undone coral]

Unity meaning the editor? i mean the built player

[open yoke]

Oh yes, the built player should run in the container and stream from within the container

[undone coral]

is your goal to stream the rendered visualization from the standalone built player from a container?

okay

have you seen https://player.appmana.com/watch/spacetable or http://player.appmana.com/bonneville ?

do you know what this is?

i think this is unity streaming with instant building from a git / plastic repo and i believe it's currently free

if you contact via https://appmana.com/waitlist

and it seems to work on mobile too

@open yoke is this helpful?

[open yoke]

Thanks, but not really. I'm looking for a DIY toolchain. Not a web-based solution/product

[undone coral]

i see

well i think you'll do a little bit more research on this, what you're describing takes years to develop

how do you plan to do the streaming?

[undone coral]

have you successfully streamed from a container?

[open yoke]

No

[undone coral]

it's okay if the answer is no

have you successfully streamed from a plain ubuntu bare metal box?

i hope this is helpful, i'm just trying to gauge where you are in this journey

[undone coral]

have you successfully built a standalone player on a bare metal ubuntu box? was it an empty project or a project that contained your assets?

[open yoke]

Yes I have

[undone coral]

okay that's good

[open yoke]

It was my project

[undone coral]

do you want to add the streaming or has it already worked on bare metal ubuntu?

it's okay to be a little grumpy

i think this looks easy and it's actually stupendously hard

[open yoke]

Streaming has worked before on the standalone build

[undone coral]

on bare metal you mean

[open yoke]

Yes

[undone coral]

which package did you use?

[open yoke]

For streaming?

[undone coral]

yes

[open yoke]

Its custom

[undone coral]

can you talk about that some more

you'll see that i've been very candid with people about all the approaches in previous chats, for people who have wanted to do this

so i don't mean to make this feel like an interrogation, i'm sorry

are you streaming to a browser?

[hexed meteor]

I'm trying to budget my memory better .... does anyone know what the memory cost of a material instance is in Unity ?

[undone coral]

@open yoke anyway i'm available to be a resource here, i think if you want an artisanal quantity of users (one user) you should not do CI/CD and you should not try to build into a container. it's important to be candid with your actual use case

[open yoke]

No I am streaming locally from outside. I use a custom GStreamer pipeline that uses shared memory copy to a Unity texture\

[undone coral]

cool - do you mean you copy FROM a unity texture TO gstreamer?

or FROM gstreamer TO a unity texture?

so you want to stream video INTO a unity texture for rendering inside unity?

[regal olive]

my spaceship is jittering. Spaceship rb is interpolate. Here is the code: https://gdl.space/cekuruzaxa.cs
I figured out that line 54 is causing it.
https://gyazo.com/044c0a364c21ba58c5d2f98d149fbbb9

[undone coral]

it's negligible

people avoid creating material instances because of their impact on rendering duration not memory

[undone coral]

is this a cinemachine camera?

[regal olive]

yes

[undone coral]

did you set it to FixedUpdate?

turn off interpolation and set the cinemachine camera to fixedupdate

and set your fixedupdate interval in your physical settings to 1/60

[regal olive]

its object jittering. i tried it with typical camera. object was jittery

[hushed fable]

Just going to hide the issue for yourself

[undone coral]

that's true but sometimes that's suitable for a prototype 😦

i am honestly not sure why the default isn't 1/60

it might as well be

[undone coral]

i think you have to have to add torque (angular forces) for it to interpolate correctly. honestly i'm not sure why moverotation would gltich

i believe you that it does

[regal olive]

torque is uncontrollate

[undone coral]

yeah

[hushed fable]

Being slightly below a common monitor refresh rate is probably good so people find out about these issues

IIRC these smoothing methods just don't work very well with objects that are constantly changing their speed

[undone coral]

it's easier if you are streaming some other audio/video source INTO unity

it's okay if you don't want to talk about this though @open yoke ... i probably know a lot more about this than anyone else you've talked to

[undone coral]

does it have to be non-kinematic?

what's the gameplay purpose of that?

@open yoke i'll just caution that the game-ci docker containers don't really successfully build most complex projects, especially on linux

they are used mainly in github actions which are VM runners

you can use github actions with your own runner if that's what you want

[regal olive]

do movePosition and moveRotation work with kinematic object?

[hushed fable]

Might work better if you do this effect manually based on input or something

[brazen umbra]

guys how can i check object like OnTriggerEnter?

[undone coral]

honestly i don't know 😦 i don't really build character controllers with rigidbodies

i would use an asset for this stuff since it's so idiosyncratic

[livid kraken]

Isnt the Unity Render Streaming package supposed to handle this sort of use case ?

[undone coral]

yes

[regal olive]

i tried rotating spaceship without moving and seems like mixing addForce and moveRotation causes jitter

[undone coral]

but as you can see, the user wants to do like, the whole rest of the problem... streaming an artisanal 1 user isn't that challenging

i think people put themselves into an absolute colossal amount of jeopardy doing a demo for someone showing streaming of 1 user

and assuming this stuff can scale

[regal olive]

i also set rb to isKinematic

thanks

now its not doing jittery stuff

[undone coral]

yeah but it's also not really doing physics now 😦

i think moverotation may not consider the "incomplete" physics you have with the add forces

i'm nto sure

there's a way to do this

[deep peak]

you can try freeze rigidbody rotation and rotate the gameobject instead of the rigidbody

or you may have to use AddTorque instead of setrotation

[undone coral]

but then what really happens is people who write C++ plugins get grumpy

[regal olive]

i can probably lerp speed when moving position to get acceleration

[hushed fable]

Setting the rotation will likely break interpolation. Afaik the result is the same with AddTorque

[buoyant leaf]

is there a way to delink particles from their attached transform?

[undone coral]

do you mean shuriken particles or vfx graph particles

you can simulate shuriken into world space

and use a parent constraint to control its transform settings

[buoyant leaf]

well its not, but yeah I want the particles to move non-relative to their parent

[undone coral]

it's not which?

is it shuriken or vfx graph?

[buoyant leaf]

so if the parent suddenly moves, the particles stay on their path and don't follow the parent

unity's particle system?

[undone coral]

that's shuriken yeah

[buoyant leaf]

didn't know it's called shuriken

[undone coral]

i think you can use parent constraints carefully

[buoyant leaf]

how?

[undone coral]

okay well the betetr question is what's the effect?

[buoyant leaf]

ngl I am not that well versed in the particle system

[buoyant leaf]

just traditional particles emitted from a transform

[undone coral]

i guess i'm not sure

[buoyant leaf]

gimme a second

I want it so when I move the object the particles don't follow

i don't want this

[undone coral]

try world space simulation

it's a checkbox

[buoyant leaf]

where?

found it

thank you so much

looks much better

[livid kraken]

Have you tried the render streaming package ? I havent but it does work with a build player right ? The rest would be handling spining up all the virtuals to scale

[undone coral]

the render streaming package is okay

the underlying streaming approach is flawed in some ways but not insurmountable ones and the developer on it is trying to fix that

[livid kraken]

We have a metaverse client and I keep trying to explain that tje scales they want wont work on webgl so Im looking into solutioms

[undone coral]

The rest would be handling spining up all the virtuals to scale
i think people underestimate this challenge not by 10% or even 100%, but by 1000%

[livid kraken]

I dont underestimate it at all

[undone coral]

i think you should try the https://appmana.com/waitlist and see what happens

[livid kraken]

Thats why I plan to pay a platform to do it if and when we need it

[undone coral]

it is free right now afaik

[livid kraken]

I saw that link yes will check it out as well

[undone coral]

the reason i know it's free is because i develop it lol

i know a lot about this stuff

two guys here were trying to use agora and were in a great deal of jeopardy

you can see that i've contributed to com.unity.webrtc, the underlying streaming approach from the unity renderstreaming package

[livid kraken]

Thats cool. How would the platform handle a multiplayer situation ? Would the server run on your side as well ?

[undone coral]

you can engineer it both ways - as a traditional networked multiplayer game or as a local multiplayer game that streams different cameras to different players

some guys are experimenting with the later and are quite happy

[undone coral]

if it's traditional networked multiplayer, that server can run anywhere

i think there are certain concerns, especially for a global game, that make that complicated

you would probably deploy the backend side-by-side with the player instances, we run our own hardware in the US

but it's very painless to try. you connect your git or plastic repo, add our plugin as a unity package, and it'll be built and deployed

no pressure though

[livid kraken]

Can the tech be used in a established cloud ?

[undone coral]

i think if you try to do this yourself, you're going to figure out everything except how to get it to run efficiently, that is what i focus on

[undone coral]

yes it's run in AWS

[livid kraken]

Ok cool. Well I'll def tell the relevant dev team to check it out

[open yoke]

Hey...sorry for the delayed reply. I was pulled into something else.

Yes I am streaming video INTO a Unity texture from Gstreamer.

[undone coral]

why would this be in a container?

what's the objective? is there on screen output?

i can be really helpful but you gotta give me the big picture here of what you're actually doing

[hallow turtle]

can anyone good with photon help me with getting a function to go off for master client? i have a maze type thing made by photon.instantiate and now im trying to destroy it all when game wins and make new maze

it works if master wins but if anyone else does it throws errors

my rpc wont work

    {
        PhotonView pv = this.gameObject.GetComponent<PhotonView>();

        //GameObject.Find("ThreeOfClubs").GetComponent<CreateThreeOfClubs>().DestroyGame();
        pv.RPC("MasterDestroy", RpcTarget.MasterClient)); //player1 = PhotonView.Find(1001).gameObject;
}

    void MasterDestroy()
    {
        if (!PhotonNetwork.IsMasterClient)
        {
            throw new InvalidOperationException($"Only master can perform this action");
        }
        DestroyGame();
    }

    public void DestroyGame()
    {
        GameObject[] walls;
        walls = GameObject.FindGameObjectsWithTag("Wall");
        foreach (GameObject wall in walls)
        {

#archived-networking might be the best place

[unique ermine]

Not sure if that's the right place to ask but it seems advanced
I'm not sure how anyone can help me but perhaps there are some smart people here.
I'm developing in unity.
I'm currently trying to make a clothing system where I can swap meshes(clothing) at runtime. This itself is not that hard I imagine but it gets a bit more complex now.
Imagine an inventory where you see your player character full body with the working clothing system, so far so good.
But in my game you actually play in first person, as it's a shooter.
This means I only have the player arms & weapon in first person.

what's the problem? how the fuck would I attach the clothing from the full body mesh to the fps arms, so when you wear a white t-shirt it would be visible on the arms.
perhaps this is important : The fps arms are taken from the player full body, so they have the same bone structure if that's important
is that even possible?
one way to 'fix' that problem would be that everytime players create a clothing item, they also have to make a second version just for the fps arms, if that's visible in first person.

[undone coral]

yes, every item has to be arted for both the POV and exterior views

[wary swift]

Same goes for animations

What looks good in 3rd person usually looks bad in 1st person

[unique ermine]

arted? Does that mean every clothing piece needs to be done twice for fps and full body?

[unique ermine]

Yeah they would be seperated.

[undone coral]

yes

[unique ermine]

Ah sad to hear. Thought it’s somehow possible to extract it from the full body and make it work somehow

Thanks a lot

[tawdry dome]

i am trying to create my own city building game (like cities skylines), and i am thinking of ways how to save terrain data, is there a way to store it in .png files each pixel is point in my grid and height is represented in 24bit integer (0 - lowest possible point, 2^24 highest possible point)

[undone coral]

you are at the start of a very long journey

[tawdry dome]

i know

[undone coral]

you can modify at runtime, save and load the terrain height and splatmaps

[tawdry dome]

ok

so can i use .png file to save heightmap?

[undone coral]

yes

you can get a texture2d as png bytes using built in unity functions

https://docs.unity3d.com/ScriptReference/ImageConversion.EncodeToPNG.html

EXR might be a better choice. depends what you're going to do with the images

[undone coral]

grid and height is represented in 24bit integer
this would be an R24 format, which doesn't exist in unity

it is simpler to use RHalf or RFloat

[tawdry dome]

i was thinking of saving it in RGB24

[undone coral]

you COULD

but there's a format that gives you exactly what you want unambiguously

[tawdry dome]

ok

[undone coral]

This isn’t a place you want to innovate is it

I mean the image format

It’s a long journey

[tawdry dome]

ok

i should look into how to do it now

[meager kite]

is there a more performant way for a newly instantiated object to find my GameManager object in the scene than to call FindObjectOfType?
because it can lag a lot when each newly instantiated object has to look through a ton of others just to find the GameManager

[high karma]

Save it on a variable at start method. Then access that variable on your other script.

[meager kite]

yeah thats what i meant by call FindObjectOfType, i might have tens of thousands of objects at a time and even one search can seriously drop frames

[deep peak]

usually GameManager and similar classes are singletons, there is only one instance of them can exist (its your responsibility to enforce this though), and they have a static field referencing themselves, and other script access them through that static field

[short atlas]

Is there a way for me to change a value of a variable that's local to a function from the onClick() event? Like is there a way for me to write something like "gameObject.GetComponent<Button>().onClick.AddListener(myFunction.value = 2)" or something?

I heard of a way that included delegating that function and creating a marker but it won't let me set the marker to an actual int or str...

[turbid tinsel]

What's stopping you from changing a variable in a class, and then read it from inside the function?

[short atlas]

The thing is, I first need to change the variable of a function once the button is clicked because the buttons are generated at runtime, which first of all is why I need to access the onClick() via code, and each button has a value that I want it to display once I click it and if I click the next one, then the next value should be displayed so I'm kind of confused on how I should add this to the onClick().

[turbid tinsel]

You can add a function to onclick, that will take the text component and the desired value as parameters, and then assign the desired value to the text component inside it

I dont think changing a variable local to a function is something that makes sense in your scenario

[short atlas]

the displaying text was just an example but in other words i just need to generate a value once a button is clicked

but the value that I need is calculated by the function that generates the buttons and i cant just call that whole function at onClick() which is why i needed it to change a local value at onClick() instead.

so i was hoping there was a method to store a value along with the generated button that can be fed back to a function on the onClick() event.

[turbid tinsel]

Try button.OnClick.AddListener(() => MyFunction( somevalue, someothervalue, anythingyouwant));

MyFunction will be called with those parameters on click

[short atlas]

alright let me try

[meager kite]

how would i create this static field?

[short atlas]

yeah that still won't work because the parameter I pass is actually a mini algorithm so it needs to be under the conditions of the other function to work properly, otherwise if its ran casually it returns a random value.

[undone coral]

?

what is your objective

[turbid tinsel]

well you gotta put it in another function, no other way

either pass the result or implement it in the other function somehow

[undone coral]

var myvar = 0;
gameObject1.GetComponent<Button>().onClick.AddListener(() => {
 // this works
 myvar += 1;
});
gameObject2.GetComponent<Button>().onClick.AddListener(() => {
 // this still works
 myvar += 2;
});

it's the same value between the two functions

[turbid tinsel]

do you need the value be changed after clicking each button?

so that the first button would display 1, next one 3 etc

if yes, you need to make a variable outside of the function
and pass in just the 1, 2 etc
and modify the variable in the other function

[short atlas]

so I have a nested for loop in a function that generates buttons, and I have a mini algorithm that tags those buttons. I also want the buttons to return the value they are tagged with when they are clicked, but that value is calculated once, and its when the button is generated.

[undone coral]

a nested for loop in a function that generates buttons
are you trying to say you are experiencing a problem using your index i in a lambda?

[short atlas]

no clue what you just said lmao

[undone coral]

this is apparently a very common issue

just post your code

[short atlas]

alright ill post snippets

[high karma]

You can assign a new local variable to i then return that new variable on the button.

[turbid tinsel]

Why dont you do
var myvar = 0
button.onclick.addlistener ({MyFunction(myvar)});
myvar += 1;
button.onclick.addlistener({MyFunction(myvar)});
etc etc

as long as myvar isnt a reference it'll work

[undone coral]

we'll see what the code is

we're about to find out

what this mystery question

is really getting at

[high karma]

lol

[undone coral]

my bet is it's an index in a listener problem

[turbid tinsel]

just post the whole function code

[high karma]

Yeah im kinda confused what hes trying to do.

[short atlas]

spawnedTile.name = $"{chars_index[focal_sector[focal_sector_indexer] + sub_val]}";
spawnedTile.GetComponent<Button>().onClick.AddListener(() => InputParser($"{chars_index[focal_sector[focal_sector_indexer] + sub_val]}"));

ABOVE IS THE THING TO TAG THE BUTTONS

formats gone off lmao

[undone coral]

hmm

there's no for loop in here

show us the whole loop

it's looking EXTREMELY likely though

[short atlas]

[undone coral]

focal_sector_indexer = Mathf.Clamp(focal_sector_indexer,0,2);
hmm

okay

[short atlas]

oh that part can be deleted

[undone coral]

all you have to do @short atlas

[short atlas]

no need for that

[undone coral]

well

i mean that clearly makes a huge difference

but okay

here's all you have to do

[short atlas]

nah cause it never reaches outside the boundary

but this loop just generated the buttons

and it tags them accordingly

but i want to make the value they are tagged with the return value of the onCLick()

[undone coral]

var finalSubVal = sub_val;
var finalFocalSectorIndexer = focal_sector_indexer;
spawnedTile
 .GetComponent<Button>()
 .onClick.AddListener(() => InputParser($"{chars_index[focal_sector[finalFocalSectorIndexer] + finalSubVal]}"));

i think it's going to be incomprehensible to you

to use the technical words

for what we are doing here

but all you have to know is, if you want the value of something like "focal_sector_indexer" at the "same time" as when you create your listener "function", you have to copy that value to a new variable.

okay? does that make sense?

problem solved

you just don't know about this problem

you're like the third person in the last 24 hours to have it

[short atlas]

yeah this is slightly confusing

its cause i dont see why i need a final sub val when thats just a value to help calculate a certain position in a chars_index

[undone coral]

guys help me

you're in the #archived-code-advanced chat

[short atlas]

cause its not the loop that doesnt work

[undone coral]

i know, i mean i fixed your problem

[short atlas]

okok ill try

[undone coral]

but you don't yet comprehend why

part of it is you write code like a crazy man

part of it is that you're not really aware of what the code means

[short atlas]

lmao people say that always

[undone coral]

for example do you know what () => {} is called?

it's okay if you don't know

[high karma]

[short atlas]

i remember using it in java

[undone coral]

lol

yes

it's a lambda!

that's right

[short atlas]

inline function or smthn

[undone coral]

it is in java

no it's a lambda

it's not an inline function

but close enough

when you declare a lambda you have curly braces right?

that's a scope

[short atlas]

yeah

[undone coral]

look at the variables you're referencing, are they declared inside the scope of the lambda?

no.

not in your original code

[short atlas]

ah

[undone coral]

so those two variables

focal_sector_indexer and sub_val

[short atlas]

lmao i didnt even think you could do this in c#

[undone coral]

every lambda looks at the same name and reads the same value

it doesn't get copied over

you need a new name for a new value

that's why we're doing var there

because the code inside your lambda hasn't executed yet

you should notice that too

so it's not like it "copies" just because you wrote the code (that's impossible)

anyway i was right

this was your issue

[short atlas]

ok let me see if it works

[undone coral]

i mean

i don't know if it's going to work

because i can't make heads or tails of what this for loop is supposed to do

incidentally if you had just done

var input = $"{chars_index[focal_sector[finalFocalSectorIndexer] + finalSubVal]}";
spawnedTile
 .GetComponent<Button>()
 .onClick.AddListener(() => InputParser(input));

you would have accidentally correctly dealt with the lambda closure pass-by-reference issue

[short atlas]

damn ill look into all this more now that you mentioned it

[undone coral]

i don't know if chars_index changes over time though

i have NO IDEA what's going on in this code

lol

[short atlas]

nah chars_index is just an array

doesnt change

[undone coral]

okay so problem solved

[short atlas]

BRO

THANK YOU

[undone coral]

but do you understand

[short atlas]

damn if you dont mind could you explain it again? i'd like to understand the lambda pass.

[undone coral]

lol

okay

[short atlas]

lmao

[undone coral]

it's okay

when you do

for (var i = 0; i < 10; i++) {
 var button = Instantiate(buttonPrefab);
 button.AddListener(() => {
   Debug.Log(i);
 });
}

every button will log "10"

because there's only one variable i, and they're all referencing the same variable i

when you declare the lambda () => {...} it DOES NOT copy the value of i in some snapshot of time

it just says, "where is the name i?"

"what is the value of the name i"?

does that make sense?

once you exit the for loop, i == 10

so when you click the button, you run Debug.Log(i), and it's 10

[short atlas]

yeah, thats what i was trying to say 😂 that it wasnt capturing it from a snapshot in time but rather calling it on the onClicked()

[undone coral]

it doesn't matter that at the moment you created the lambda, the value of i was 1 or 3 or whatever

yes

so to deal with this, because this is almost always what you want:

for (var i = 0; i < 10; i++) {
 var button = Instantiate(buttonPrefab);
 var finalI = i;
 button.AddListener(() => {
   Debug.Log(finalI);
 });
}

[short atlas]

ohhhhh

i see

[undone coral]

bUt tHe nAmE finalI iS tHe sAmE

well, it is declared anew every execution of the for loop

[short atlas]

so you clone 'i' in that moment in time and leave that clone unaffected

bro this is making so much sense

[undone coral]

so there are 10 finalIs, one belonging to each lambda

with a copy of the value

okay great

[short atlas]

lmao tell ur boss to give you a raise

if you work

[undone coral]

it's called final because this is an error in java, and you fix it by declaring an "effectively final" or "final" variable

[undone coral]

lol

[short atlas]

i just met a messiah

[undone coral]

don't worry you will thrive

keep on programming like a crazy man

[short atlas]

ahahah appreciate it

anyway thanks.

[brazen umbra]

guys any way to check this gameObject is raycasted or not?

[wooden cedar]

Did you cast a ray and hit it?

[slender stag]

👋 Hello, I opened a project that I haven't worked on in a while and it looks like the .meta file for a dll was filled with null bytes

The .meta file Assets/Core/TankCore.dll.meta does not have a valid GUID and its corresponding Asset file will be ignored. If this file is not malformed, please add a GUID, or delete the .meta file and it will be recreated correctly```

Screenshot from VSCode

Unity went into Safe Mode, but how can I get the guid of the file through the asset database, because I cannot do much when the editor is in safe mode (Edit: Editor scripts also do not work, any other way to access the asset database to get the guid?)

[austere jewel]

If it's just full of null bytes there's nothing you can do apart from deleting the file and letting Unity remake it

and hoping nothing was explicitly referencing it via GUID

@slender stag

[slender stag]

It contains monobehaviours that is in my scenes

So idk if deleting it will unassign (or make them missing)

[austere jewel]

I have no idea, but if you are using source control surely you can revert it

[slender stag]

I mean, if I had source control, I wouldn't be asking for help lmao (I wish I used it though)

Is there a way to browse the AssetDatabase directly?

[austere jewel]

Unity uses the GUID in the dll's meta file to resolve the scripts. (and uses the file ids it generates from the full names of the classes in it)
You're going to have to find where you've used a script in your game and look at the file (be it a prefab, scene, or scriptable object file) to find the GUID that it's trying to reference

You're then going to have to delete that broken meta file, and get Unity to generate a new one.
Then you're going to have to close Unity, and replace the GUID it generated with the one you found.

You're going to have to do manually through text. I do small modifications with Rider fairly often with its find and replace as it's fast as hell for that sort of thing.

You should really start using source control, because reverting a single file change certainly is easier than going through this rigmarole 😛

[slender stag]

Found common guid: b01367d0e380e624084e66cbfccc2546

And yes ima add it to the repo lol (This was a side project, decided it was not necessary to add to the git repo... till now lol)
🤞
Status: Done!

[slender stag]

It works!!!

[livid kraken]

Anyone know what is SRPBatcher.Flush and what does it do? This is running GLES3.2 on Oculus Quest 2

it seems to be connected to the reflection probe settings on the mesh renderers. With off I'm not seeing it

[fresh vortex]

how can i get count of non-persistent UnityEvent listeners?

[regal olive]

Don’t cross post ☹️

[fresh vortex]

it's been like 10 min already

and there is huge ongoing topic already

[novel plinth]

have you checked the docs? bet you're not!..

[fresh vortex]

read my question again

bet you didint read it

[novel plinth]

oh haha 🤣

either way, easy to tackle, no?

Make a List.. each time you add the Listener, add it to the list as well

or just an int as a counter, that would do the trick too

[wispy terrace]

I've got a base class from which many other classes derive from:

[brazen umbra]

yes

[wispy terrace]

But when I create an instance of the class, the lists are empty:
allFurniture.Add(new Furniture("chair", "Chair", new string[] { "wood", "basic", "brown", "cheap", "rustic" }, new string[] { "sit" }, null, null, null));

Everything else gets set correctly. My first aproach was to ask for the lists directly on the base class constructor and assign them plus any derived class could add additional entries to the lists in their own constructor, but it didn't work

[fresh salmon]

You have an issue in the constructor of Item. You loop over the actions and add them to the tag list (2nd foreach)

[wispy terrace]

Just noticed, thanks

But that doesn't solve the issue

They both are empty at the end

And I am definetly adding entries in, at least, one

[fresh salmon]

Place a breakpoint on the constructors, and step through

I don't see anything wrong with the code rn

[wispy terrace]

Yup there is nothing wrong with the code, however, there is definetly something wrong with me xD

Found it, human error

[wispy terrace]

I almost never debug through breakpoints because of the hustle of setting it up, but that was the way to go for sure. Thanks!

[livid kraken]

 Texture2DArray textureArray = new Texture2DArray(textures[0].width, textures[0].height, textures.Length, TextureFormat.ETC2_RGB, true);
       
        for (int i = 0; i < textures.Length; i++)
        {
            for (int j = 0; j < textures[i].mipmapCount; j++)
            {
                var mipData = textures[i].GetPixelData<byte>(j);


                textureArray.SetPixelData(mipData, j, i);
            }
           
           
        }
        textureArray.Apply(false);
``` Any idea why this adds a full white alpha to each slice in the texture array even when the source textures have no alpha ?

[livid kraken]

actually something fucky is going on. enve if I set every element of mipdata to 0

the alpha is there in the editor

the displayed size does not shrink as well

but if I open up the asset, its all 0

not a single 255 or f

[brazen umbra]

i will away waiting for you 👍
