[spare island]

the same general idea at least

[leaden ice]

It sounds like you might have had some exposure to the callstack

[spare island]

i kind of skipped from C# straight to assembly for a little

and then did some stuff building circuits and RAM and such (in minecraft, i can't afford to build real life ones lol)

[spare island]

@leaden ice thanks for the help seems to be working fine!

[shell scarab]

how do I check if this thing is on or off?

[leaden ice]

Depends what that is

Share some context?

SteamFriends.ActivateGameOverlayInviteDialog((CSteamID)current_lobbyID);

I currently have this to open the invite menu, but it just opens steam overlay with a list of friends, how do I get the menu where you have those "invite" buttons?

I have an system where players can pick up dropped weapons by pressing F. But when the player picks it up, the weapon doesn't go to the hands transform but rather above their head. The weapon is still a child of the hands transform upon pickup. The hands transform works indicated by the rocket launcher. The pistol and the knife doesn't apply

Here's all the code associated:
https://hastebin.com/share/ibiqahohih.csharp
https://hastebin.com/share/kazamawofe.csharp

[soft shard]

I would check the pivot of your hand transform and the pivot of your weapons, you should also make sure you are zeroing the local position of your weapons after parenting it, if all your weapons have different origins, they will be positioned differently once they are a child, you could give each weapon its own parent and move the base of the weapon (the part the hand should cover) to the origin of that parent, this way when you set a weapon as a child and zero the local position, it will be on the parent that contains the specific weapon positioned where you would like

i have this gameController structure i want to pass into this script. but i cant drag and drop it in there. I assume its because there are children attached? Are there any workarounds?

public class TileClick : MonoBehaviour, IPointerClickHandler
{
    public GameObject gameController;
    public void OnPointerClick(PointerEventData eventData)
    {
        gameController.GetComponent<GameController>().clickTile(transform.position);
    }
}```
if i try and select it from the available objects it says there is a type mismatch but i dont understand why

[knotty sun]

you cannot set a scene object onto a script, only an instance of the script attached to a gameobject in the same scene

[proper valley]

so i have to create an instance of GameController?

[knotty sun]

that you already have, you need to attach this script to a game object and assign there

[proper valley]

i attached it to an object, but it doesnt let me drag and drop the GameController object in the object field

[knotty sun]

show the inspector

[knotty sun]

that is a prefab not a scene object

[proper valley]

ah
do i have to make a GameController prefab then?

[knotty sun]

no

[proper valley]

do i assign the function/object when making a new tile instnce?

[oblique spoke]

Most likely want to assign the scene references when you instantiate the prefab.

[knotty sun]

yes

[proper valley]

how do i do that?

i already have a script attached to the tile, in the start function, how to i get the GameController object?

[knotty sun]

after instantiating the prefab get a reference to the TileClick script and set the reference to the GameController

[knotty sun]

you should hold a reference to it in the script that instantiates the prefab

[proper valley]

The tiles are instanciated by the tile handler script, do i put the reference in there?

ah ok

[knotty sun]

if GameController is a singleton it's even easier

[proper valley]

i got it working, thanks!

[grim cypress]

I am a beginner in unity requesting some support
Can someone guide me on How to make a search dropdown and then use the selected option as a variable input into a script
Kinda like the search bar on top of google maps ui

[worthy raptor]

alright so not sure if this would fall under animation or coding, but I'm trying to get my characters attacks to actually deal damage. I've only dealt with platformer movement, but this new project I'm working on has 4 directional top down movement, and I genuinely have no idea how to get my character to attack. I've looked up multiple tutorials, but I just can't seem to find something that works with my character

for reference the asset package I'm using doesn't have a visible "weapon" and most tutorials require an attack point object to be created on attack

[cosmic rain]

Well, there are several main methods:

• deal damage on actual physical hit, when your weapon hits the target.
• deal damage at certain timing(like at certain point of animation), regardless of whether the weapon physically hits the target.

There are also more complex approaches that are a combination of the two.

You should decide what kind of approach you want to follow first.

[worthy raptor]

Since my character sprite doesn't have a weapon attached to it, I think the second option would work a lot better. Especially considering the attack has 4 seperate animations for each direction

for example this is what my character sprite looks like

[rigid island]

this is quite easy to do (code wise)
the only annoyance would be getting a dropdown-like window under an InputField (aligning UI )

[mellow barn]

bumping this, deltaTime indicates we're not on a timescale of 0, is there something else i should be aware of that might be causing problems?

[simple void]

typeof(Object).IsValueType
You can actually use reflection to check for almost anything, templates, generic types, unmanaged, etc

For value types, if you create one in a function it's on the stack. If you have a reference type holding one, instead of a seperate memory block and a pointer to it, it literately holds all the values inline

ie. If I had a class A which holds an instance of class B, where sizeof(B) is 24 bytes, sizeof(A) is 8. But if class A holds an instance of struct B with the same size, sizeof(A) is 24.

[shell scarab]

Should avoid reflection in unity, causes extra gc overhead and is slow

[spare island]

maybe they mean for just testing

[shell scarab]

maybe. But i dont think typeof and sizeof is really going to affect it, i think its mostly the stuff in System.Reflection

[wide terrace]

Is typeof reflection? I thought that was compile-time shtuff 👀

[spare island]

i think typeof is compile-time and GetType is reflection

[twin egret]

i'm having a weird issue where using Camera.WorldToViewportPoint returns different results for the same position, could something like SRP be the cause?

[wide terrace]

Whew. Good. I just wrote a small pile of code leveraging it 😅

[spare island]

the difference between the two would probably be insignificant in performance anyway

[wide terrace]

Oh I'm sure you're right. Especially in such small quantities as what I'm doing. The thought that I unwittingly may have stumbled into reflection was just a bit of a spook

[twin egret]

for reference, running from the same input position and camera i get these results

[wide terrace]

Can you share the relevant code?

[twin egret]

yeah, give me a second, gathering everything rn

[shell scarab]

Well, technically, i think typeof is reflection but just known at compile time.

[twin egret]

oh wait, i found the issue. camera wasn't in the same position

[jolly kettle]

what's the standard method for handling different bullet impact effects based on the materials of an object?

my initial thought was using CompareTag but I have stuff that needs tags for other gameplay reasons

[leaden ice]

Put a component on the surface that has details about it including what kind of impat effect

[jolly kettle]

and then just grab the script for each shot?

Seems reasonably efficient

[leaden ice]

yes presumably you're using OnCollisionEnter or a raycast or something, you just TryGetComponent to find the "surface material" script and do what you need to do

[simple void]

Yeah I'm just saying for testing whether it's a value type

[shell scarab]

why do you need to test if its a value type?

[spare island]

i dont need to i just want to know how to

[shell scarab]

ohh okay

[devout parrot]

My game world has ~10,000 objects, and I only want the objects in a specific range of the player to be visible. However, the objects refuse to be enabled when they enter my sphere collider. Here's the code to turn them off at launch:

private bool init = true;
    // Attached to objects
    void Start()
    {
        if(init)
        {
            gameObject.SetActive(false);
            Debug.Log("Outside Render Distance!");
            init = false;
        }
    }

Here is the code for the sphere collider:

void OnTriggerEnter(Collider other)
{
    if(other.tag == "Decoration")
    {
        Debug.Log("Spawning Object");
        other.gameObject.SetActive(true);
        Debug.Log(other.gameObject.activeSelf);
    }
}
    
void OnTriggerExit(Collider other)
{
    if(other.tag == "Decoration")
    {
        Debug.Log("Despawning Object");
        other.gameObject.SetActive(false);
        Debug.Log(other.gameObject.activeSelf);
    }
}

This feels like this should be simple, but I just can't wrap my head around this. Any assistance would be appreciated.

[somber nacelle]

well first of all, unity already has built in frustum culling so anything not in the camera's view frustum will already not be visible. second, occlusion culling is also a thing so you can cull even more objects that are occluded by other objects so you don't need these trigger messages for stuff like manual culling

and if trigger messages aren't working then you need to use this to evaluate why: https://unity.huh.how/physics-messages

[devout parrot]

I don't believe this will help in my case. The game environment is a procedurally generated planet, and the objects placed on it are also procedurally generated. Because the planet itself moves, occlusion culling won't work. For the debug messages, the objects that are initially within the sphere collider report a collision, and activeSelf is true.

[somber nacelle]

well frustum culling already exists and works with proc gen stuff, and the camera's clipping far plane can be used to not render objects beyond a certain distance, so unless you are doing anything special in OnEnable/OnDisable or you need specific components to not update when those objects are out of range, what you are doing is mostly pointless

[shell scarab]

Um are the objects disabled? Cus it won’t send the messages if they’re disabled.

[somber nacelle]

that would be one of the things covered in the link i sent regarding physics messages

[meager tinsel]

Running into an issue, where I'm just trying to get some simple background music to play. I start up the game, but it doesn't go. Anyone have any thoughts as to why?

using UnityEngine;

public class AudioManager : MonoBehaviour
{
    //Set up a variable for playing music.  I'm setting them up to be separate, music and sfx.
    [SerializeField] AudioSource musicSource;
    [SerializeField] AudioSource sfxSource;

    //Now we'll create a variable to keep the music and sound effects in an AudioClip.
    public AudioClip background;
    public AudioClip jump;
    public AudioClip winLevel;

    //This function will set up the background music to play when the game starts.
    private void Start()
    {
        musicSource.clip = background;
        musicSource.Play();
    }
}

[somber nacelle]

any errors in the console? have you confirmed that the clip is set on the correct audio source and that the audio source is active and enabled?

also have you ensured that the editor isn't simply muted?

[knotty sun]

and you dont have audio muted in the editor

[meager tinsel]

Oh, it's saying there's no audio listeners in the scene? I'm not sure what that means.

[somber nacelle]

your camera does not have an AudioListener component. which means you either have no camera, you manually removed the AudioListener from the camera, or you just added a camera component to some object manually

[meager tinsel]

Gotcha! So, what should I do if I want the music to continue to play to the next level? Since it only plays for that level, and then stops once it loads the next level.

[knotty sun]

you need to make your AudioManager and the Sources DDOL

[meager tinsel]

DDOL?

[knotty sun]

Dont Destroy On Load

[meager tinsel]

Ah, gotcha.

Running into this error. Trying to set up this script so when the character goes hits the trigger, it plays.

public class FinishLevel : MonoBehaviour
{
    [SerializeField]GameObject victoryTextObject;
    [SerializeField] float levelLoadDelay = 5f;
    [SerializeField] string levelToLoadName;

    //Reference into audio manager script.
    AudioManager audioManager;

    //Setting up sound stuff here.
    private void Awake()
    {
        //Setting up the sound effect here.
        audioManager = GameObject.FindGameObjectsWithTag("Audio").GetComponent<AudioManager>();
    }

    private void OnTriggerEnter2D(Collider2D collision)
    {
        //Taking advantage of player tag here for collission stuff.
        if(collision.gameObject.CompareTag("Player"))
        {
            StartCoroutine(LoadNextLevel(levelToLoadName));
        }
    }

    IEnumerator LoadNextLevel(string newLevel)
    {
        //Enable victory text.
        victoryTextObject.SetActive(true);

        //Play sound effect.
        audioManager.PlaySFX(audioManager.winLevel);

        //Wait for levelloadDelay number of seconds.
        yield return new WaitForSeconds(levelLoadDelay);

        //Load new level here.
        SceneManager.LoadScene(levelToLoadName);
    }
}

[vague radish]

any one know why triangle is disappearing?

[devout parrot]

For now, I've turned off the initial despawning script. The objects now despawn correctly when the sphere moves away from the object, but it should appear when the sphere moves back, but it doesn't.

[somber nacelle]

yes because OnTriggerEnter won't be called on a disabled collider

so again, what you are attempting to do is pointless

[wide terrace]

GameObject.FindGameObjectsWithTag("Audio")

returns an array of GameObjects. Arrays don't have a GetComponent() method

[knotty sun]

Is this AI code?
objects returns an array

[rigid island]

smells like AI code
..actually I dont even think AI code would fuck this one up tbh

[devout parrot]

That's not what I'm reading from the documentation. Every entry regarding collision triggers say that they can trigger on disabled objects.

[somber nacelle]

no, it says it will call OnTriggerEnter on disabled MonoBehaviours, but the colliders still need to be active

which means the gameobject must be active

[meager tinsel]

I was following a tutorial, but I think I should be using FindWithTag instead?

[devout parrot]

So I need to disable just the mesh renderer instead of the entire gameobject? Let me try that and I'll report back.

[knotty sun]

you should be reading the docs

[somber nacelle]

i mean sure, but again frustum culling already takes care of this for you

you are not saving any performance by doing this manually

[devout parrot]

The objects are spawning and despawning as intended. The issue is that the colliders are still loaded, causing performance issues. Also, since every object is dynamic, fustrum culling won't work.

[somber nacelle]

wdym frustum culling won't work? frustum culling will cull anything not currently visible by the camera within the camera's view frustum

and if colliders being enabled is causing performance issues, then using trigger messages to enable/disable those colliders won't exactly work because a disabled collider wouldn't have trigger messages called on it

[devout parrot]

I managed to get my culling script working. I switched from a collision sphere to comparing Vector3.Distance. It works flawlessly with good FPS now.

[smoky escarp]

Guys, does anyone know any sane way of enabling nullability per asmdef, that would work in both IDE and Unity?
I know I could turn it on in csc.rsp, but that's for the whole project, I just want to turn it on for specific core projects that are more pure c#

[rigid island]

cant you do that inside the asmdef file already?

I'm stil fuzzy on asmdefs

google says something about

  "additionalCompilerArguments": [
    "-nullable:enable"```

https://stackoverflow.com/questions/64229527/customizing-csproj-in-unity-enable-nullable-reference-types

[smoky escarp]

Thanks mate
I think both of these would work on the entire Unity project, not specific asmdefs
For example, Asmdefs have a nice checkbox for "Allow unsafe code" but nothing similar for nullabiity
Basically it would be ideal if I could plug in "additionalCompilerArguments" into asmdef somehow
Maybe this Build.Props thing can be customized

[rigid island]

oh for the inspector ? yeah tats beyond my skill level 😛

[smoky escarp]

I just hoped Unity has something inbuilt I am not aware of, there is probably some painful way to hack it

[proper valley]

im having issues making this empty game object collide with other objects. i have some tiles which the object passes trough if i have isTrigger set to true in the collider settings, but can detect the collision via script. however if i set isTrigger to false, it collides with the tile and doesnt get detected by the script

these are the settings for the tile

[rigid island]

well are you using OnCollision method?

also how do you move the rigidbody

oh nvm I see its a kinematic on this empty

[proper valley]

OnTriggerEnter(Collider other)
oh im using this

[rigid island]

you need OnCollisionEnter if its not trigger

check here though
https://unity.huh.how/physics-messages/collision-matrix-3d

collisions are very tricky with kinematic

you need the other to be at least dynamic for OnCollision to work

[proper valley]

private void OnCollisionEnter(Collision other)
    {
        Debug.Log("clic");
        if (other.gameObject.tag == "tile")
        {
            Debug.Log("Colliding with tile");
        }
    }```
`other` in this case is still a game object right?

[lean sail]

https://docs.unity3d.com/ScriptReference/Collision.html
the type is right there, its a collision

[proper valley]

got it, thanks

[plush ridge]

Could someone point me in the right direction to set up handling player turns?

[rigid island]

setup an array

scroll through indexes

[plush ridge]

Thank you thats what I needed. I was overthinking it

[rigid island]

when in doubt , use the KISS principles 😛

[plush ridge]

Thanks!

[shell scarab]

Can someone help me understand materials rq. When are they coppied? I need to make sure I don't get a memory leak (I think that can happen with CoreUtils.CreateEngineMaterial)

So I create a material in object A and pass it to object B through a method, where it stores the material locally to object B. If object A destroys that material, object B's reference will go null because it points to the same material right?

[simple void]

Yes, materials are referencetypes

[shell scarab]

when are they copied/new instances made?

[rigid island]

iirc when you modify the materials properties

[meager tinsel]

Just trying to make an instance of an object moving back and forth between two points, but the gameObject in question keeps going off to the right. Not sure what to do to fix it.

using System.Collections;
using System.Collections.Generic;

{
    //Creating to the points where the enemy will patrol.
    public GameObject pointA;
    public GameObject pointB;

    private Transform currentPoint;
    public float speed;
    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        currentPoint = pointB.transform;
    }

    // Update is called once per frame
    void Update()
    {
        //We're going to set it so the object goes between point a and b, and then reversing it once it hits the right point.
        Vector2 point = currentPoint.position = transform.position;
        if(currentPoint == pointB.transform)
        {
            rb.velocity = new Vector2(speed, 0);
        }
        else
        {

        }

        Gizmos.DrawLine(pointA.transform.position, pointB.transform.position);
    }
}

[wide terrace]

Sprinkle in some Debug.Log()s - see what's going on with your values.

[meager tinsel]

Okay, so they're all getting procced, so I'm not sure what the issue is. It's not making it go right, when it should be going back and forth.

[wide terrace]

I meant log your values, like transform.position, currentPoint.position, Vector2.Distance(transform.position, currentPoint.position) etc. :)

But in any case,

Vector2 point = currentPoint.position = transform.position;

This seems suspect... currentPoint.position is always exactly equal to transform.position, so not only are your point transforms likely moving, but Vector2.Distance(transform.position, currentPoint.position) is likely always 0 👀

[meager tinsel]

Okay, you were right, it was supposed to be currentPoint.position - transform.position;

Though now it just seems to make it go right, hit the point B, then go left and just...go off course.

[wide terrace]

I'm not sure... this code does depend on pointA being to the left of pointB. And I think it'll also break if speed is higher than the framerate. It also won't be too happy if point A and B are within 0.5 units of one another. But failing those conditions, you'll need to log the values to see what's going on

Debug.Log(
$@"currentPoint: {currentPoint == pointA.transform ? "A" : "B"}
currentPoint Pos: {currentPoint.position}
transform Pos: {transform.position}
distance: {Vector2.Distance(transform.position, currentPoint.position)}"
);

[calm echo]

If it doesnt need Rigidbody based movement...

time += Time.deltaTime * speed;
var t = Mathf.PingPong(0,totalTime);
targetObj.position = Vector3.Lerp(start,end, t/totalTime); 

Something like this will make it simple

[meager tinsel]

Oh, uh, neat. Where should I insert that, if it's simpler? I'm not opposed to using it, I'd just want to know what I need to cut out to do so.

[calm echo]

{
    //Creating to the points where the enemy will patrol.
    public Transform pointA;
    public Transform pointB;
    //Rigid body for moving the body.
    private Transform targetObject;
    public float speed;
    public float totalTime;
    private float currentTime;


    void Update()
    {
        currentTime += Time.deltaTime * speed;
        var t = Mathf.PingPong(currentTime, totalTime);
        targetObject.position = Vector3.Lerp(pointA.position, pointB.position, t / totalTime);
    }

    //This is just something I saw in a tutorial to help visualize the points for ease of use.
    private void OnDrawGizmos()
    {
        Gizmos.DrawWireSphere(pointA.transform.position, 0.5f);
        Gizmos.DrawWireSphere(pointB.transform.position, 0.5f);
        Gizmos.DrawLine(pointA.transform.position, pointB.transform.position);
    }
}```

[meager tinsel]

Okay. I'll give this a shot, thank you!

[calm echo]

edited just now ^

[meager tinsel]

I'm, uh, getting a few errors, gonna try to sort em' out.

[spring creek]

It is a single missing line causing all of the errors btw

[meager tinsel]

Oh, it is?

[spring creek]

If you copy pasted the above code, then you missed everything that should come above it.
The using statements I mean

[meager tinsel]

Oh, gotcha

[spring creek]

Ah I see the MonoBehaviour error is on line 1, so yeah. No usings at all

[meager tinsel]

Okay, so that's inside Unity, but getting this error, and the sprite just dropps to the ground.

[spring creek]

Something on line 21 is null.
NullReferenceExceptions are extremely common.
So get to debugging and figure out what reference on line 21 is not assigned

Debug.Log or the debugger with a breakpoint would tell you immediately

[meager tinsel]

Okay, I've got it moving.

Okay, this part is done. Thank you everyone for your assistance with this.

[rigid moon]

hi i need help a bit im trying to change color on a texture using this, i did create a new texture at runtime, with RGBA32 format but idk why the alpha channel just reduce the value of the color like this

i did tick alphaIsTransparency when creating the texture

not im not sure why

[dusk apex]

Maybe you should explain what has happened and what should happen instead.

[rigid moon]

oh yea my bad so basically instead of the transparency like this, the alpha doesn't change the transparency but the value instead basically darker/ lighter

[dusk apex]

So if the alpha was zero, what would you see?

(I understand that you'd want it to be invisible but what actually happens instead?)

[rigid moon]

it turns black

it lost the color completely

[dusk apex]

Can you show the inspector for the material?

[rigid moon]

sure

[dusk apex]

What shader? Is it a transparent/defuse shader?

[rigid moon]

i dont think so it just this

[dusk apex]

I'm a bit occupied but I'm pretty sure it's to do with a setting. Try following the shader transparency docs https://docs.unity3d.com/Manual/StandardShaderTransparency.html

[dawn nebula]

So in my case, I have a level, and in that level there are entities. Enemies, collectables and structures are entities. If a player kills an enemy, or collects a collectable, or destroys a structure, I need to track that so when the level is reloaded the state is maintained. How should I go about doing that?

As a start I was thinking of creating a Entity ScriptableObject for each type of entity. The Entity SO's would have some entity ID, a reference to the prefab, and any other useful data about the entity. I would then have a EntityInstance SO to represent an instance of that entity in the level. These SOs would contain an entity instance ID, and a link to the Entity SO which should be spawned.

I would also have a EntityManager in the levels which would have a list of these EntityInstance SOs. On scene load, these managers would be given some LevelData, which contains a hashset of IDs that represent the entity instances that are still alive. For each EntityInstance that it has, the EntityManager checks if its ID is included in the hashset. If yes, spawn, if not, don't spawn.

This sound good?

[inner charm]

Anyone have a good tutorial on how to create 2D armor overlays on my humanoid sprites?

[cold parrot]

put another sprite in front of the base character?

[little meadow]

Seems a little cumbersome, but I might be missing something. I'd say just implement some interface ISaveable on all such objects that you pass a LevelData when you wanna save/load and they write/read what they need there. It might have a Dictionary<id-type,object> or just a HashSet<id-type> if you only care about the "is destroyed/collected" thing, and you'll add data by ID there. Aaand yeah, you'll need a system that assigns IDs to these objects automatically, which might be 10% annoying, but once you have it - you're good for saving whatever you want, I think. 🤔

Well, that's the case where you do all the setup on the scene and then you destroy the already collected things... the other direction would be more optimal if you care and better if you wanna randomly spawn those objects anyway... in which case your idea is good, but I think it can go without all those SOs and just have a manager with prefabs, and it can auto-assign IDs and all that as it instantiates them and call some initialize method 🤔

Hi, I have a voxel game with a bunch of chunks, i'd like to have all of these to be asynchronously updated, like all these chunks dispose themselves if they are too far from the player, but i dont know how to create a asynchronous method without an await inside

[knotty sun]

dont cross post

[inner charm]

Yes exactly

[cosmic rain]

async void method should work

Or a coroutine

Or just a condition check in update

[slate imp]

Asnc void didn't worked because I did not have await in the method
I used a task.run but now I have another issue... Because I have a bunch of objects and small updates it creates a bunch of tasks and makes it even worse XD

I will need to pool the tasks and computation

[cosmic rain]

Wdym? You don't need an await..?

If it requires you to use an await, then you're doing something wrong.

[slate imp]

If their is no await, the method will be executed synchronously even with the async keyword

[cosmic rain]

No, it wouldn't.

Though, in unity it would be executed on the main thread, so sort of, yes.

You do need an await inside the method of course.

You can await Task.Yield() for it to yield until the next frame.

[slate imp]

i could yes, but the issue is still the same, i now have too much tasks creation, do you think we can pool tasks ?

[cosmic rain]

Share your code. At this point I've no clue what you're doing.

You don't need tasks if you execute it async on the main thread.

[slate imp]

The code is a bit complicated, here is a simplified version :

public ChunkManager{
/// Create a bunch of "chunks" and give them the player camera
}

public Chunk {
  void Update(){
    if(isTooFarFromPlayer()) isVisible = false
    else isVisible = true
  }
} 

but i have like 8 000 chunks

[cosmic rain]

Where are you creating the tasks that you're talking about?

[slate imp]

on the update of the chunk

[cosmic rain]

Show the actual code

I don't see any tasks in that snippet you shared.

[slate imp]

https://pastecord.com/ugufuwyvaj.cs
The chunk code

[proper valley]

private void PlaceTile(int x, int z)
    {
        Vector3 position = new(x * TILE_SIZE, 0, z * TILE_SIZE);
        GameObject tileInstance = Instantiate(tile, position, Quaternion.identity);

        Tile tileScript = tileInstance.GetComponent<Tile>();
        tileScript.Position = new Vector2(x, z);

        tileDict[new Vector2(x, z)] = tileScript;

    }```
i have this function to create new tile game objects. each tile has also a script attached with fields such as position. I want to make a dict using the pos and Tile object as key-value pairs. however `tileDict[new Vector2(x, z)] = tileScript;` throws an error saying "NullReferenceException: Object reference not set to an instance of an object"

[gloomy path]

does anyone know how to make particles splat onto surfaces? im trying to make a blood splay that prints onto surfaces but I cant find any ways online, any help would be great

[cosmic rain]

This is the chunk manager code, not chunk code. And also, it doesn't even seem to be complete? Where are you storing your 8k chunks?

[mossy snow]

hopefully the log is spewing errors at you with this because this has no chance of working with Task.Run

[knotty sun]

your tiledict is not initialized

[proper valley]

whoops, thanks

[slate imp]

Yes, the naming is not correct, but chunkmanager is on each chunk. Its complete, im storing the chunks in the following file :
https://pastecord.com/gukopozulo.cs

This is where i create the chunks :
https://pastecord.com/hylyzusyce.cs

[slate imp]

I have no logs but have some issues in some points yes, but its not the most problematic part, having it asynchronously take more performance than having it synchronous

[mossy snow]

I guarantee you, even if this did work, this will have far worse performance than doing it all on the main thread. You might have a chance if you were using Jobs and doing the distance computation there, but I think the whole strategy is fundamentally wrong

are your chunks not arranged in some order?

[slate imp]

not sure about this

[slate imp]

Yep, because it was something that is not related to the player action directly, i thought i could send it to another thread to ensure spawning and despawning a chunk shouldn't lag the player

[cosmic rain]

First of all, most of unity API you can't call from a background thread. Seeing how destroying a GO is the main part of what you're trying to do, that's not gonna work.

Not to mention that you're probably gonna get a hell of a race conditions.

[slate imp]

race conditions ?

[slate imp]

oh...

[cosmic rain]

To answer your initial question, you can destroy the chunks async on the main thread - over several frames.
It can be as simple as an current iterated chunk int in your manager and iterating the chunks in update with that index. Then you limit how many chunks you want to iterate per frame.

[cosmic rain]

Google. It's too much to explain here.

[slate imp]

oh okay i see, so i would iterate through chunk in the VoxelTerrain class instead of inside each chunk

[slate imp]

i seen what is it, i didn't know the term but know what it is.

I don't see much where i would have race condition, because each chunk is looking for himself, the only thing that could change would be the position of the player, and even that would not create an issue, i dont have much shared data

[cosmic rain]

You might have a race condition if you access any of the chunk data from the main thread, while it's being destroyed(not that it's possible on a background thread anyway).

[slate imp]

Ohhh that way, yeah I understand the issue

[floral nacelle]

Hello I need help with my game design, as everything breaks when I create a build for an android game on my macos. Everything is out of position and not set in the positions I placed them. Can someone please help me with this?

[leaden ice]

What are the things that are out of place? UI elements?

[dusk apex]

This doesn't sound like a code question. Try #💻┃unity-talk and make sure to explain/provide information. You shouldn't be looking for someone to fix your problem but rather just post your problem and anyone who knows how to fix your problem (provided you give all of the necessary information) might do so.

(I'm assuming it's a screen ratio / anchor problem.

[marsh carbon]

Hi, is there a way to find out more about the stack of calls to my functions in a crash dump?
My game crashes at a random moment, while nothing useful has time to be recorded in the log file.

[leaden ice]

Did you make a development build?

[marsh carbon]

yes

[leaden ice]

and what do you see in the log file when it crashes?

usually a hard crash wouldn't come from any C# code

That's more likely to happen from lower down in the engine itself

[marsh carbon]

The person who had the crash bug didn't even have a folder on the way
"AppData\Local\Temp.......\Crashes"

everything is written to the log file a moment before the hang and departure

[leaden ice]

if it "hangs" before crashing it might be an infinite loop

[visual flare]

you don't have to, it's a good feature support to have in rider

[marsh carbon]

that's the problem of finding out exactly where, because not only our code is in the project, it can also be code in assets

[rigid island]

yeah just saw it was rider looked like a sus link at first lol
I did it, I dont even use rider

[visual flare]

hehe thanks

[pearl burrow]

hi guys

i added a render texture camera to my project and now i have 3 cameras.
One is an overlay camera that only renders some parts of the UI
antoher is the main camera that renders to a texture
and the 3rd is the camera that shows to the player the rendered texture

now at first all my interaction were off and i found a solution by changing the physics raycaster with a script i found online. The problem is with the overlay camera where the drag event position seems like they changed with the new camera added ( the one that shows the render)
here is a before and after

and the script i used before is a simple screentoworld point of the mouse position

public void OnDrag(PointerEventData eventData) {
        Vector3 screenPoint = eventData.position; 
        screenPoint.z = planeDistance * 0.8f;
        dragPosition = overlayCamera.ScreenToWorld(screenPoint);
    }
}```

how should i edit this to make it work on the new camera? The script i found that changes the physics raycaster is this https://github.com/riveranb/UnityRTEvents/blob/master/Assets/RTPhysicsRaycaster.cs

it uses ViewportPointToRay instead of screenpointToRay

in addition the overlaycamera has a canvas in screen space camera since I'm rendering 3d elements in it

hope anyone can help

[severe onyx]

Hi all, I'm trying to update an animation layer's mask via code - How do I do that?

[leaden ice]

Can you be more specific about what you mean by "an animation's layer mask"?

[severe onyx]

Sure thing. In an animation's animator component, you can set up layers, and give each a weight and an avatar mask. I would like to change that avatar mask via code at runtime.

my usecase - I have a baseLayer with an avatar mask that masks just the upper half of the body, but I only want this in effect, when the character is holding something with their upper body (eg. a gun). When they're not holding said item. The baseLayer's avatar mask needs to be empty so it plays the regular set of animations without any masking.

[leaden ice]

You mean this?
https://docs.unity3d.com/Manual/AnimationLayers.html

[severe onyx]

Yep that's the one. Just need to know how I can change the avatar mask on the animation by code

[leaden ice]

I think you would use this:
https://docs.unity3d.com/ScriptReference/Animator.SetLayerWeight.html

For example have two layers with different avatar masks. Have one with a weight of 0 and one with a weight of 1

Swap them when you want

If I understand what you mean

[severe onyx]

Yep that would work, but then I would need to create duplicates of the baseLayer for every type of masking I need. If I can just set it's avatar mask to none during runtime, it'll save a bunch of work

[leaden ice]

so this exists...
https://docs.unity3d.com/ScriptReference/Animations.AnimatorControllerLayer.html

I'm just not sure how to get access to it at runtime

[severe onyx]

that seems like it's an unity editor only thing

I don't think I have access to that via the runtime

[leaden ice]

It's part of https://docs.unity3d.com/ScriptReference/Animations.AnimatorController.html but you only can get the RuntimeAnimatorController at runtime AFAIK

[tropic plank]

hello i wanted to ask if there is a solution for corner collision with gameobjects,i have been looking and trying to code it,the results are not working as intended

[tropic plank]

the intended results is that the player object(being a square2D) when it collides with another player with a corner first it will kill the opponent, however what happens is that it works when it wants too

[weary sail]

I have a 3d labarynth generator that changes dynamically, but I don't want the walls to be able to change while they're on screen, is there any way to implement this?

[knotty sun]

you can check if something is visible ?

[weary sail]

But I have to disable the renderer to hide the wall, then it doesn't work

At least I think

[lean sail]

You'll have to specify more at what the issue is, rather than "it works when it wants". You have logs but you should print out more useful stuff like what it hit. Printing out just literal strings isnt gonna tell you much. Also this looks incredibly hardcoded

[lean sail]

What does hiding the wall have to do with your initial question?

[weary sail]

I don't want the walls to be shown or hidden while they are in the camera's view

[weary sail]

isVisible ignores objects that are in the way

I want it to be able to detect if an object is in the way causing the wall not to be visible

Actually if anyone has a better idea it would be appreciated as this method makes it incredibly cheesable by just facing away from a wall and walking backwards into it

[lean sail]

I'm somewhat confused by what you're actually trying to do so heres a link on detecting if something is visible
https://discussions.unity.com/t/how-can-i-know-if-a-gameobject-is-seen-by-a-particular-camera/248
As for your last message, you could just do some physics query or have a trigger collider to let you know which objects are close to the player. Then just dont change walls which are also very close

[weary sail]

So am I to be honest, I ended up combining isVisible with a translucent material that is basically invisible to the naked eye but not to the isVisible check, and I also added the radius around the player.

[barren hazel]

Hi my animation events are firing twice and I have no idea why? Any help?

[leaden ice]

What makes you think they're firing twice?

[barren hazel]

Well if I stick a debug log on the method that receives the event, it prints twice

[leaden ice]

Ok so - can you show us the inspector of this object with the animator?

[barren hazel]

This is the event

Ive checked, there is only one event in that inspector, its not two overlapping

[leaden ice]

I would like to see the inspector

not of the event

[barren hazel]

And I used debug log to verify that there is only one source, a single component on my main player char

[barren hazel]

Sure which component?

[leaden ice]

The entire object

perhaps you have two copies of the component for example

[barren hazel]

SoundController is the one receiving animation events, and there is only one

[leaden ice]

which script has the function?

[barren hazel]

SoundController

[leaden ice]

how did you verify that exactly?

Have you tried Debug.Log($"Animation is called on {GetInstanceID()}", this.gameObject);?

[barren hazel]

Not instanceId, let me see

Called twice, same instance ID, and same gameobject name (which I tried earlier)

[leaden ice]

Alright so how are you p[laying this animation clip exactly?

Perhaps the animation is quickly starting twice or something

what does your AnimationHandler script look like

[barren hazel]

Its unrelated to this essentially, its more for procedural movement of the character, not the animation states itself

This is the animation state to transition to it

I guesss it could transition to itself?

Wait

There is a checkbox for that let me disable it and see

Ah

That'll be it

Thanks for rubber ducking for me @leaden ice

[leaden ice]

nice

[inner charm]

Any ideas why my static variables (inside a public class) is not saved between scenes in WebGL builds, while it works just fine (between scenes) in the game preview thing in Unity?

public class StaticItems : ScriptableObject
{
    public bool looted;
    public string itemName;
    public Sprite inventoryIcon;
}

From console we can see that the item is set to true, and then we switch scene back and forth and it's false. Could it be related to this part? Unloading 34 unused Assets to reduce memory usage. Loaded Objects now: 2107.:

[spring creek]

Yes, probably due to the unloading. Generally you do not want to mutate SOs. Treat them as immutable as much as possible

[spring creek]

You should probably just use a POCO (plain old c object. Just a class) for this

[inner charm]

Oh, I see. I thought it was the "standard" kind of object for data persistance between scenes

[spring creek]

No, definitely not. It should not be used for that situation at all. People SOMETIMES try to force it, but it is bad practice, and not recommended

[wide terrace]

Quoth the manual:

When you use the Editor, you can save data to ScriptableObjects while editing and at run time because ScriptableObjects use the Editor namespace and Editor scripting. In a deployed build, however, you can’t use ScriptableObjects to save data, but you can use the saved data from the ScriptableObject Assets that you set up during development.

Data that you save from Editor Tools to ScriptableObjects as an asset is written to disk and is therefore persistent between sessions.

[inner charm]

Mind blown, thanks dude

[spring creek]

SOs are kinda like prefabs. Just variants of data. Use them when you want to swap in and out presets of data in the inspector

[inner charm]

Cool, I'll check out POCO, thanks again!

[spring creek]

Keep in mind, to persist between scenes, they need to be referenced. POCOs will be garbage collected like normal when no references exist (like when a scene is unloaded). So look into additive scene loading or DontDestroyOnLoad as well. The object referencing the POCO needs to be in a scene that is not unloaded

[inner charm]

Great info, thanks

So much new stuff, I just want to create the best game ever (TM) on my first try with unity 😉

Kind of funny how it's recommended by: https://gamedevbeginner.com/how-to-make-an-inventory-system-in-unity/

[wide terrace]

Huh... indeed. This seems peculiar 🤔

He does go on to say that you can separate the data which can change from that which doesn't using a POCO which references the scriptable object... But I don't understand what he's getting at with the Inventory SO there, unless he's just saying that you could use it to configure default inventory contents

[oblique spoke]

I don't think that manual quote is directly related to data persisting in SOs between scene loads.
@inner charm I believe you can avoid SO being unloaded if the next scene is referencing the SO early enough.

[wide terrace]

Ah you're right - it's just talking about persistence to disk...

I've often heard it discouraged, but is treating SOs as mutable runtime data just a matter of personal preference, if you are aware of the caveats of doing so?

[inner charm]

Oh, that seems correct

[oblique spoke]

Not aware of technical reasons against mutation beyond those lifetime and editor behaviour caveats. Some people are very into stateful SOs.

[knotty sun]

I see nothing wrong with it, after all SO's are the only data structure supplied by Unity which are both editable in the Editor and live outside of the scene context

[wide terrace]

Interesting... I feel like the majority of conversations I have witnessed err towards just treating them as immutable data. But I have no horse in this race as of yet. I'll have to poke around some more. I appreciate the insights 🙂

[leaden solstice]

Caveat is that in Editor environment you're mutating your asset and it will persist, unless you instantiated your SO.
And if you do instantiate your SO there is no real reason to use SO.

[oblique spoke]

Though same rules apply to prefabs

[wide terrace]

My internet is having a real struggle at the moment and it's unclear if I'll be able to continue this conversation, but are you saying instantiate a SO as in like Instantiate()?

[leaden solstice]

Yes, looks cursed? Yes. Is it cursed? Yes.

[wide terrace]

Fair on all counts 😅. The discrepancy between the editor and runtime behaviors does seem mighty off-putting

[leaden solstice]

Thing is that using SO directly means you are also coupling "initial data" and "runtime representation", which is not always same.

and cleanup issue when you having some weird event stuffs on it, etc

[wide terrace]

It certainly adds up to a very persuasive argument against doing so. I'll have to find some time to experiment a little more and see if I can appreciate any qualities of stateful SOs in practice, but I do think I may be leaning in the opposite direction.

[inner charm]

My intended use for SOs are to check them if certain conditions are met, that for example allows progressions to another scene

So when I loot a key, that scriptable objects looted property is true. This means that the key is never displayed again in it's original location, and it also means I can pass a certain door, and progress to the next scene.

This works great in the editor, I can loot the key and move back and forth between the scenes, but in my build it "forgets" the scriptable object when switching scenes ... 😦

First line in the manual:
"A ScriptableObject is a data container that you can use to save large amounts of data"

Later in the manual:
"In a deployed build, however, you can’t use ScriptableObjects to save data ..."

[cosmic rain]

The first line refers to the editing time. It is indeed a good way to store data that would remain mutable during the game.

[serene stag]

i think in deployed builds also scriptable objects works fine to save data. but i use for small amounts ony.

[cosmic rain]

No they don't. They are just an asset. Thinking of modifying them is as crazy as thinking of modifying a mesh or a texture asset and expecting the changes to carry on to the next session.

[lean sail]

the whole conversation above was specifically how SO are not to save data in a build also

[inner charm]

I don't think it's all that crazy to expect the compiled version to act like the editor version

But that might just be me being an enthusiastic noob 🙂

[lean sail]

id say just the behaviour having to be figured out is a good enough reason to keep them as immutable data. At least for me, id rather just go along with what i know of using plain c# classes than run into a random bug

[cosmic rain]

There are many differences between editor and a build. SOs are one of these differences. In fact, they're specifically an editor tool. I guess there's a lot of misconceptions around them.

[young tapir]

Am I missing something from this? It should be working the same as the others I've got but for some reason nothing happens :/

[inner charm]

Sigh, this will be another argument for my team to switch to UE instead. It's a pity, I started to like Unity 😐

[cosmic rain]

So you think SOs(there are no SOs in unreal) in unreal work the same way in the build?😅

I can guarantee that any similar feature in unreal would also not work as you expect.

[inner charm]

Why would you say this?

[simple egret]

Add logs. Maybe isCasting is false so it returns early.
Also do not use ?. on anything deriving from UnityEngine.Object, it doesn't work properly (it bypasses the "destroyed in the scene, but not null yet" state of Unity objects)

[dawn nebula]

which suuuucks

[young tapir]

isCasting is just a class variable of active, it should be enabled & disabled acording to when the spell is active and inactive

Why is there a random } lmao

Oh they're just messy nvm

[simple egret]

Yes, but at the time the method runs it might be false.

Use logs or the debugger to find out if the code runs

[young tapir]

It runs every frame, no?

[simple egret]

You return; if !isCasting.

Did you write this code?

[young tapir]

If it's not casting I don't want it to run, will it still not run when isCasting is true?

[simple egret]

It will run if it's true, that's guaranteed.
But you said that "it doesn't work" so you need to find oit why
It will not overlapsphere if isCasting is false, which is why I'm asking these questions

[cosmic rain]

Because I don't see why you'd bring UE here. SOs don't make Unity inferior to UE in any way.

[inner charm]

You can express those opinions without stating that I think something I don't think - if your opinion is solid it should stand anyway.

(I also agree that I don't think that this makes unity inferior, however this will give my team more reasons to bash unity)

[leaden solstice]

Argument is that you shouldn’t bash the engine for the reason that you are using features in unintended way 🤔

[young tapir]

Got it working without much stress, the 4 debug messages I had spamming every frame were causing just a tiny bit of lag

(From around 90FPS to like 15)

[simple egret]

Not sure how that's related to the issue in any way, but glad you got it solved
Next time make sure to include more information on what the issue is, though

[deft dagger]

hey im trying to change my projects editor version from 2022.3.8f1 to 6000.0.11f1 but i got this error what should i do ?

and i tried before to switch the unity editor version but when i tried to build before i always got a gradle build error

[simple egret]

Are you planning on using the package it's mentioning in the error? multiplayer.samples.coop

[sterile cradle]

why is my audio crackling?? I've already disabled doppler effect tried changing to streamed and yet still this happens I didn't do anything prior but it just started happening (though I did add a lot more objects so that may be why) but otherwise I have no idea.

[deft dagger]

im not sure to be honest, i use the unity relay multiplayer, so im thinking its needed for relay ?

[simple egret]

Okay, so in that case let's not remove it, so you'll need to install Git on your computer to proceed

[deft dagger]

so do i just install git from my browser and restart unity ?

[simple egret]

Yep, restart your computer in between, because Git makes change to the PATH so it can be executed from anywhere

[deft dagger]

ok i will try and comeback

[deft dagger]

and do you know anything abouut the gradle build fail when im trying to make a new build ?

[simple egret]

There will be more errors on a failed build, check the console for other messages. You'd want to ask that in #📱┃mobile though, if the issue does not come from your own code

[deft dagger]

okay thanks a lot man

[deft dagger]

heyyy im back :D, what should i do here

[simple egret]

Make a backup and update all

[deft dagger]

it says that there are deprecated packages in package manageer and shows me this what should i do ?

do i just continue to use it like normal ?

[knotty sun]

remove it, use the Visual Studio Editor package

[deft dagger]

oh i just realised its not even the normal visual studio

i dont use visual studio code

[simple egret]

That's one more reason to get rid of it

VSCode uses the Visual Studio Editor package too nowadays

[deft dagger]

damn

i dont even know these codes xd

[simple egret]

Yeah it's package code (TextMeshPro here). Close the project, go to where it's saved and delete the Library folder, and open the project again

That will force a full reimport of package contents

[deft dagger]

okk it will take longer though right ? cause its gonna reimport everything again or something

[simple egret]

Yes

[deft dagger]

ok i will try that, thank you a lot again :D

i got the same errors even after deleting the library folder

[simple egret]

Ah these don't come from the library folder. If you don't need the TextMeshPro examples, delete the folder mentioned in the error messages

Assets/TextMeshPro/Examples_Extras

[deft dagger]

yeah i dont think i need them i just use tmp for the ui stuff

[simple egret]

Yeah when you use it for the first time it asks you whether you want to import examples along with the base stuff

do you know what the fmod sub-system is ?

[simple egret]

It's a sound engine that can replace the one Unity has built-in

#🔊┃audio might be able to help you for this one

[plain moon]

I have issue with scrollbar on IOS devices. In WebGL and android it's works fine but in IOS it's laggy and jittering
But it's still default Unity Scroll

[deft dagger]

thankss

[balmy dove]

without using the dampen settings et al, exactly how were you supposed to make it such that the cinemachine virtual camera rotates with the follow target focused in the center?

[near birch]

guys i am having issues with unity

like this

it is still loading

[narrow sphinx]

Anyone have any good design patterns they use for save/load systems? In particular, how parts which rely on the save state get their references.

[deft dagger]

do you know anything about this or where im supposed to ask about it ?

[fleet gorge]

open task manager and force close unity editor. alternatively restart your pc.

[fleet gorge]

i do it the stupid way and serialise a dictionary

at the start of the game i call Load() in my save system

[near birch]

none

[narrow sphinx]

Like a dictionary that holds all the various refs to things you have saved? Sounds pretty good tbh

[fleet gorge]

my save system is a dictionary<string, string> so I end up casting stuff whenever I do numbers 😦

but syntax is very clean

[near birch]

dawg 😭 🙏

[fleet gorge]

SaveSystem.variables["username"] = "uldynia"

and it will get written to the save file next time

[fleet gorge]

i dont have access to your pc so idk how to help you

restart your pc

[fleet gorge]

uh if your unity is on an external drive it probably has issues

[near birch]

its not 😭

[fleet gorge]

broad statement hold on imma see where the logs folder is

[near birch]

you mean editor logs?

[fleet gorge]

idk if its a hubs issue or editor issue

[deft dagger]

do you know anything about this ?

[fleet gorge]

not really

i never published ios before

[near birch]

what is mandetory ASLR?

[deft dagger]

the problem is im not publishing on ios either

[fleet gorge]

https://techcommunity.microsoft.com/t5/windows-security/turn-on-mandatory-aslr-in-windows-security/m-p/1186989

[deft dagger]

i want to publish on android and windows

[fleet gorge]

check your package list because apple sdk is in there

[fleet gorge]

forgot to mention: my savesystem takes 10% of my game's cpu usage(or 10% of the system's cpu, idk how profiler works). I need to change this.

users here said that I should keep the file handle open.

[frigid turtle]

Hello guys, how can i update Google Play purchases? Is it enough to update Unity com.unity.purchasing package?

[tiny mountain]

Any idea why this gives this error? Using the .jslib plugin at Assets/Plugins/WebGL, trying to call the function from that plugin

[leaden ice]

sorry which function are you trying to call?

[tiny mountain]

First three on the second screenshot

used this same plugin in an older version of unity for another project

called it the same way

for some reason this gives an error now

[leaden ice]

can you narrow down which one it is exactly?

i.e. by commenting them out one by one (is it all of them)?

[tiny mountain]

rebuilding takes a lot of time, but if that's the only option alright

[leaden ice]

I guess I'm trying to see how you determined it was exactly these functions causing the issue

[tiny mountain]

previous build worked fine, after i added those three it stopped working

also sorry if i sound rude, did not mean that

[leaden ice]

no worries, didn't feel any rudeness

[leaden ice]

Can you maybe show more of the js code? I think this may be a problem mostly on the JS side.

[rigid island]

what is "Google Play purchases" and what does updating mean in this context?
This sounds very much related to #📱┃mobile though
Edit:
Oh I see you're talking about IAP?

[tiny mountain]

that's the whole file, just these functions

[leaden ice]

does your HTML file have any javascript?

[tiny mountain]

sorry for late response, i fixed it, it's a silly mistake

it was this thing

[leaden ice]

oof

[swift falcon]

anyone know of any .net libs i can use to make a vitual audio input from a unity application, or even a .net lib to make one myself?

[near zephyr]

can someone please help me, im currently making a game, but i have absolutely no knowledge of coding so i just watch some tutorials, but now i want subtitles to show when i walk trough an audio trigger but the subtitles wont show up

[eager yacht]

Something that may help you in the future:

• Open your jslib/etc in vscode
• Ctrl+Shift+P > Change Language Mode > JavaScript
• Now you'll have some basic JS coloring/syntax/partial error help

[rigid island]

you would have to show the setup you currently have and any related code. Also this should be moved to #💻┃code-beginner

[weak perch]

Hi, I have an object which acts as the collider and rigidbody for a gameobject but doesn't hold the main script. It's de-parented on start. What would be the best way to link a collision on that object back to the object with the main script?

[near zephyr]

oh sorry, ill go there

[rigid island]

NAudio might have that feature

its complex library but powerful

[weak perch]

It's the sphere in this case, the player vehicle holds the controller and manager script

[rigid island]

#💻┃code-beginner

[weak perch]

Ah no worries

[swift falcon]

yea i was told about that before but the link they sent was bad and didnt go anywhere.

[weak perch]

Can i ask about NGO stuff there as well

[rigid island]

ngo stuff in #archived-networking

though frankly from your question you should wait a while before doing networking

[rigid island]

the github?
https://github.com/naudio/NAudio

[swift falcon]

yea it was on reddit and it just didnt work its weird. XD

[weak perch]

Ik what im doing dw i just want to know the least janky way to do it haha

[rigid island]

you might need another plugin with this though

[rigid island]

least jank is always using event systems

[swift falcon]

yea maybe, im not really seeing anything to make a virtual audio input e.g makeing my own virtual mic to use in other applications

[weak perch]

I dont think i could do it with event systems

Basically i need to access the manager script from the sphere when it collides because i need to send data from the object it collided with to the manager to be stored in a network variable

But i dont want to just have a script with a reference on the sphere because thats not great

[rigid island]

yes you do that with proper referencing

[rigid island]

who says that

use as many scripts as you need

anything else is nonsense complexity added on

[weak perch]

Fair enough you're right i am overcomplicating it

[rigid island]

I'm still trying to understand exactly what you're going for here
Are you going for something that already exists like "virtual audio cable"

[weak perch]

Thank u

[knotty sun]

but you need a script on the sphere to detect the collisions anyway

[chilly surge]

A classic case.
Most people eventually will have to write some JS at some point in their career, and a lot of people go "okay I don't care about JS, this is just an one off task, I'll just raw dog it with notepad and zero tooling" and wonder why they have a bad time and blame it on "JS bad."
There are good reasons why code channels here require people to have IDE set up to receive help, because practically any programming language is terrible to work with without tooling, JS or else.

[modern creek]

I'm building a hex-based world where some tiles have integer based movement costs (usually just 1 or 2). Should I use NavMesh for this or just roll my own pathfinding?

(I've never used navmesh)

[rigid island]

probably your own with A* if you need precision

just dealing with tilemap though is annoying

[modern creek]

Yeah.. I think I previously wrote some hex based nav code but.. I remember it being a big pain in the butt

[rigid island]

the redblobgames snippets were kinda difficult for me to adapt to unitys tilemap coordinates on hex

[modern creek]

Like having to convert to a custom coordinate system.. cubal? cuboid? from some website

redblobgames was it, I think

[rigid island]

yes redblob is goat

just a pain how unity did their tilemap system the formulas dont translate 1:1

[modern creek]

yeah

I'm not sure I'll use unity's tilemap system.. for this game the world will be a pretty small set of hexes and won't change so.. tilemap might not be the right hammer for this nail

[rigid island]

if you are able to make your own would be easier

[modern creek]

oh yeah I vaguely remember writing this

[rigid island]

I just...too much math for me

[modern creek]

and basically just being like "🤷‍♂️ well redblob says it works"

no idea what that chunk of code does tbh

[rigid island]

hah yea

[swift falcon]

so im finding alot of things, it will allow me to make unity work with virtual audio devices and be able to select them, however it cannot make them, so ether ill need to make my own driver OR i need to find a drive and a .net lib that allows me to make as many as i like in this case i dont see anyone useing more then 6. but ill also need to be able to make more as well as ill need to be able to make virtual outputs so that other applications can feed in to this program there for allowing me to make my own custom DAW, onec that small little issue if figured out e.g how i want to do it, then ill be set.

[rigid island]

I got pretty far with the hex movement though, and few basic attack types / patterns

[modern creek]

haha "black god damned magic"

yeah maybe I'm afraid to open this can of worms again, i dunno

[rigid island]

https://www.redblobgames.com/grids/hexagons/#range-intersection
this and everything under is basically what I needed and it made my head bust

[modern creek]

yeah

in this (year-old?) chunk of code i wrote, it's basically that:

looks like something that can take a tilemap x and y and convert to/from the cube/axial Q/R/S

i remember it busting my head but.. theoretically? once I do the hard work of A* and conversion from x/y to q/r/s it "should" be easy to consume

[rigid island]

A* is probably the easier part tbh

I was doing point top btw

[modern creek]

point top?

[modern creek]

it looks like i have world-to-tilemap-to-hex mapping working in this old demo

oh right, orientation of the hexes

yeah it seems like i was doing point top too

this project i'm working on now will be in 3d, but the "map" will be 2d internally.. probably will do cinemachine and isometric

the models i have came with animations and everything

[rigid island]

ala xcom?

cause thats one of my fav games

[modern creek]

i think so? i can't exactly recall xcom, I didn't play it

remind me again - turn based strategy sorta thing?

[rigid island]

grid turn based action strategy game

[modern creek]

yeah

[lyric basalt]

its remind me Ratch & Clank

[modern creek]

so this game is actually just going to be a web demo of a board game

the assets come from a video game that didn't succeed like a decade ago

i probably ought to not share it though 🙂

... and like that poof he was gone

🙂

[rigid island]

I feel exclusive to have seen the sneak peek

[modern creek]

in any case! I suppose i'll have to warm up my brain for the hex stuff again.. seems better than using navmesh

ha

it's on a pretty short timeline and it'll be public, so.. I'm sure you'll see me post about it from time to time again 🙂

[lyric basalt]

same i feel like vip

[rigid island]

navmesh just feels clunky for a hex but ig it can work

its a* anyway at the end of the day

[modern creek]

i'm trying unity6 for the first time, given URF is irrelevant for this, and the client wants it purely in web

apparently unity6 has some great improvements to "Unity Web" aka WebGL

We'll see. 👀

[rigid island]

Oh yeah heard that too. Looks promising

[modern creek]

I'm sorta diving all-in on this one.. the project will be with 3d assets, animations, etc.. if Unity6 can handle this all and get me 30+ fps and a reasonable load time.. I'll be impressed

Although tbh more with myself since I'm a 2d game dev, this 3d shit is all new to me. I'm a dinosaur. 😛

[rigid island]

besides the assets its not that much different in unity thankfully

[modern creek]

Yeah, just a lot of stuff to learn.. stuff I'm "familiar" with but not an expert in.. Like, I'd say I know my way around the UI framework pretty well.. but meshes, cinemachine, and rendering is all stuff I haven't really needed to really dive into yet so.. it'll be a journey.

[cunning burrow]

LoadSceneAsync isn't working for me...

[leaden ice]

what isn't working? Also what are these two unrelated pieces of code and how are they related?

also why is that first coroutine... not actually yielding on anything?

Doesn't seem necessary for it to be a coroutine

[cunning burrow]

Well I'm not sure why but I thought it needed to be in one, didn't change anything tho. It just instantly loads the scene

[leaden ice]

well you haven't shown enough here for us to understand what it is supposed to do differently from that

[cunning burrow]

the second code is when all the other stuff is loaded it previously directly loaded the game scene which causes some lag spike, I thought I could async it and then activate the game scene at that point

[leaden ice]

the second code is when all the other stuff is loaded
But.. hjow are you checking that? Where is it running?

Show the rest of the code

[cunning burrow]

in update it checks the progress of a bunch of data requests handled by the data manager, if all the checks pass and all the data is loaded it waits for the animation to get to the end before loading the next scene

if (!LoadingAnimator.IsInTransition(0) && LoadingAnimator.GetCurrentAnimatorStateInfo(0).normalizedTime > LoadingAnimationReferenceTime + 0.56f)
            {
                LoadingAnimationReferenceTime = -1;
                LoadingOperation.allowSceneActivation = true;
            }```

@leaden ice

there's not much else to the code idk what else you are looking for

the loading screen takes time to fetch the data from the server, so the line
LoadingOperation.allowSceneActivation = true; is only called once all that and the animation finish

[leaden ice]

This code is just sitting by itrself in a text file alone?

I have no idea when this is running

[cunning burrow]

in update ...

[leaden ice]

Well time to Debug.Log the animation reference time and what normalizedTime is coming out of your animator etc

(you could/should probably use an animation event for this)

[cunning burrow]

umm no all of that was fine. I had SceneManager.LoadScene there before, not to mention there are other checks before it, the game scene shouldn't be loading instantly, the async thing is just not working idk why

and the animation is fine, it is very specific to have a smooth transition

alright I fixed it

just don't put LoadSceneAsync in Awake

[quaint crypt]

how can i make onvalidate run only after a value has been completely changed in the inspector for an int let's say, and not while typing the integer into the inspector field, thus making weird valiudations. e.g.: i want to enter 123, but it starts validating after i've typed 1

[steep herald]

In a project where scenes are never loaded additively, what's a working flow to clear all data from a static class whenever loading a new scene? My problematic constraint is it has to be prior to awake on any object. Hooking onto sceneloaded fires after awake on monos in the scene

I understand I could manage with a mono singleton but I'd like to know if it can be done differently

[leaden ice]

https://docs.unity3d.com/ScriptReference/EditorGUI.html
https://docs.unity3d.com/ScriptReference/EditorGUI.DelayedIntField.html

(with a custom editor)

[leaden ice]

better to just not use static variables as they have no tie to the Unity scene lifecycle at all as you are seeing

[steep herald]

I find myself with a decent amount of monos living in the scene just to support the solver. I was hoping I could find a workaround to keep the count lower. Anyhow, thank you

[quaint crypt]

thanks so much

[weak perch]

hey, could someone give me a hand with structuring an item system? right now i'm using a system with abstract classes. it has a scriptable object base with a total uses variable and an abstract use method. each different item works off of this, but the problem is that each method requires different parameters for the use method

i want to be able to randomly pick them so they should all have the same base class

[leaden ice]

each method requires different parameters for the use method
Why? What are the parameters? Why pick an abstract class for this

Inheritance usually ends up being an antipattern for an item system

It's usually better do go with a composition/tagging system

[weak perch]

how would that work? ive not heard of that before

[leaden ice]

Imagine you have:
Item < Weapon < Sword < WoodenSword
< Armor < Shield < WoodenShield

How do you check if a given Weapon is made of wood? Or if an item can be held? This structure doesn't help us

Instead just make something like:

public class Item {
  public string name;
  List<ItemComponent> components;
}```
or 
```cs
public class Item {
  public string name;
  List<Tag> tags;
}```

Tags can be something like:
```cs
public class Tag {
  public string name;
  public float value;

  public bool ValueAsBool => value != 0;
  public int ValueAsInt => Mathf.FloorToInt(value);
}```

Then you could have a "damage" tag, a "wooden" tag, a "holdable" tag

etc

durability, whatever you need.

youi can even make these things serializable so you can set them in the inspector

and this doesn't force any particular item to have any particular set of tags

a health potion doesn't need a "damage" tag

[weak perch]

ahh i think i get u

[leaden ice]

but it might have a "consumable" tag and a "healing" tag

[weak perch]

and you could have methods inside those tags that dictate how you'd do that?

[leaden ice]

well the method wouldn't be in the tag

but your player might have an Attack() method that does something like:

if (equippedWeapon.HasTag("Damage", out float amount)) {
  DealDamage(amount);
}```

in this scenario Item has a function that is checking if a given tag exists and getting its value if it does

You can also do some fancy stuff with enums and delegates in a modified version of this if you want to get fancy

[weak perch]

this is very clever i really like this

especially because it will save me loads of time as im working with networks

[leaden ice]

yeah you'll want to set this all up to be serializable then ofc

[weak perch]

so for items that spawn projectiles i can use one base method for separate server/client objects

[weak perch]

yeah thats all good

im not going to have loads of items its a mario kart type system

[leaden ice]

Ah I see

[weak perch]

lots of variations basically

but this is perfect tysm

[weak perch]

another question, could tags have different data to each other?

say a 'boost' tag also had the boost amount and duration

or the 'spawner' tag had the prefab it needs to spawn etc

[queen saffron]

Hello, i'm having this bug upon swapping between scenes. The first "chess" plane represents the main scene ,3 axis scene represent the secondary scene which i intend to translate between main to secondary.
in the runtime, upon a top click on the "Enter Editor Mode" which aims to move to secondary scene ... it makes the scene 1 infused with scene 2... why is that happening?

[somber nacelle]

are you perhaps loading the scene additively instead of in single mode?

[queen saffron]

wait it actually is lol

i'm dumb haha

[spare island]

You could add a List of objects ig

and treat those like parameters, it might get messy though

Usually in those kinds of situations I'd be using a separate component on that object

[queen saffron]

how can i store a game object and not let it destroyed upon loading a new scene? i put it in a singleton class but it resets with new scene

[naive swallow]

https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html

[queen saffron]

i did use this function on the selected gameobject but i think i could be using it wrong

public class LoadEditor : MonoBehaviour

{
    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {

    }

    public void LoadEditModeScene()
    {
        if (GameManager.Instance.activeGameObject != null)
        {
            DontDestroyOnLoad(GameManager.Instance.activeGameObject);
        }

        SceneManager.LoadScene("Editor");
    }

    public void UnloadEditModeScene()
    {
        SceneManager.UnloadSceneAsync("Editor");
    }

}

I'm using a button to trigger LoadEditorModeScene where i hoped it would store gameobject and load the scene called "Editor"

[dusk apex]

Show your implementation of DDOL (the Singleton script)

[queen saffron]

public class GameManager : MonoBehaviour
{
    // Static instance for Singleton
    private static GameManager _instance;

    // Public property to access the instance
    public static GameManager Instance
    {
        get
        {
            if (_instance == null)
            {
                _instance = FindObjectOfType<GameManager>();

                if (_instance == null)
                {
                    GameObject singletonObject = new GameObject();
                    _instance = singletonObject.AddComponent<GameManager>();
                    singletonObject.name = typeof(GameManager).ToString() + " (Singleton)";
                }
            }
            return _instance;
        }
    }

    // Prevent the Singleton from being destroyed when scenes are loaded
    private void Awake()
    {
        if (_instance == null)
        {
            _instance = this;
            DontDestroyOnLoad(gameObject);
        }
        else if (_instance != this)
        {
            Destroy(gameObject);
        }
    }

    // List of game objects
    public List<GameObject> gameObjectList = new List<GameObject>();

    // Active game object
    public GameObject activeGameObject;

    // MORE nonrelated code
}

[dusk apex]

    public void LoadEditModeScene()
    {
        if (GameManager.Instance.activeGameObject != null)
        {
            DontDestroyOnLoad(GameManager.Instance.activeGameObject);
            Debug.Log($"Set active object to DDOL {GameManager.Instance.activeGameObject}");
        }
        else
        {
            Debug.Log($"There wasn't an active object to DDOL");
        }

        SceneManager.LoadScene("Editor");
    }```Try to log if there simply wasn't an object to set to DDOL

Else you're likely manually destroying it somewhere

[dusk apex]

The log states that cube zero was set to DDOL

[queen saffron]

its funny that i don't remember using destroyed in scripts other than singleton class

[dusk apex]

The inspector for your singleton manager instance likely isn't the same as that which was printed

This looks very unconventional ```cs
// Public property to access the instance
public static GameManager Instance
{
get
{
if (_instance == null)
{
_instance = FindObjectOfType<GameManager>();

            if (_instance == null)
            {
                GameObject singletonObject = new GameObject();
                _instance = singletonObject.AddComponent<GameManager>();
                singletonObject.name = typeof(GameManager).ToString() + " (Singleton)";
            }
        }
        return _instance;
    }
}```

Why do you need to find the object if it's sure to be in the scene and would have set itself to the instance on awake?

Do you've got race condition issues?

Try to avoid accessing external objects in Awake methods to avoid the race conditions (assuming something has attempted to access the manager before it sets itself as the instance)

In fact if you access the manager instance before it calls it's awake, it'll not set itself as DDOL because the instance check in it's Awake would not ever be null.

tldr: if instance is not null when awake is called, the game manager will not be made DDOL

Log this to see if the manager was made DDOL cs // Prevent the Singleton from being destroyed when scenes are loaded private void Awake() { if (_instance == null) { Debug.Log($"{this} has become the manager and was set DDOL"); _instance = this; DontDestroyOnLoad(gameObject); } else if (_instance != this) { Debug.Log($"{this} was Destroyed because a manager already exists"); Destroy(gameObject); } }

[queen saffron]

i made it to validate that there is only 1 GameManger and only one can access it at a time and prevent loss of data or a change in data simultaneously.
what do you mean accessing External objects? all i've been used gameObject and the instance itself.

[dusk apex]

Why does the getter need to check if the manager exists in the scene and has not set itself as the instance?

[queen saffron]

Active GameObject:
  None
Current Main Tool:
  Tool: none
Current Transform Tool:
  Tool: none
Current Brush Tool:
  Tool: none
2D Counter: 0
3D Counter: 0
Draw Line Color:
  Color: RGBA(0.000, 0.000, 0.000, 0.000)
Draw Line Material:
  None
Game Objects:
  None
 has become the manager and was set DDOL
UnityEngine.Debug:Log (object)
GameManager:Awake () (at Assets/Source/Script/GameManager.cs:52)
UnityEngine.GameObject:AddComponent<GameManager> ()
GameManager:get_Instance () (at Assets/Source/Script/GameManager.cs:25)
BrushKit:Update () (at Assets/Source/Script/BrushKit.cs:44)

[dusk apex]

My advice would be to not set the instance anywhere else other than in the Awake method and that nobody should be attempting to access the manager (or any other object) in their Awake - relative to external objects.
They should only be modifying values on themselves in Awake with no dependency on other objects in the scene
Use Start to avoid race condition

[queen saffron]

ahh so probably it's all behind the get functionality emm

aight thanks man for the assistance i will look more into get later on.
but just make things clear,
the whole issue is probably related to Wake or the get?

cause you just made me more confused about it sry

[dusk apex]

Not a hundred percent certain but the getter looks like a band-aid solution to avoiding race conditions (a manager already exists in the scene but has not set itself as the single instance yet)

[queen saffron]

i just replaced awake with start but it initalized the values from the beginning

[dusk apex]

Show the method

[queen saffron]

if you notice in the editor view, after i added a game object called cube, i have a 3d counter that increased and kept the same after scene swap

[dusk apex]

The singleton should assign itself as the single instance in Awake. No one should be calling the manager instance in their awake method.

My concern is with this being none after cube zero has already been set as DDOL (it's the active game object) - assuming you're showing the inspector after the log message .

[queen saffron]

weird thing...
cause this is how i initalize it with these values
and after adding cube 0 and swap i get this while other values are still preserved

[dusk apex]

Show your console logs

[queen saffron]

one second

[dusk apex]

I'm not sure which object being access threw your nre but the game manager with the missing object references indicates that the object was destroyed. When do you call LoadEditModeScene?

[queen saffron]

i called it upon triggering a button "Enter Editor Mode"

the follow error log message is resulted from attempting to print out the singleton class

[queen saffron]

yeah the cube doesn't appear cause it is destroyed somewhere

[dusk apex]

Maybe don't load a new scene that very frame after setting DDOL

I'm assuming you aren't destroying the cube anywhere

[queen saffron]

would you think that probuilder runtime objects are destroyed automatically upon scene swapping?

like i need to override it

[dusk apex]

    public void LoadEditModeScene()
    {
        if (GameManager.Instance.activeGameObject != null)
        {
            DontDestroyOnLoad(GameManager.Instance.activeGameObject);
            Debug.Log($"Set active object to DDOL {GameManager.Instance.activeGameObject}");
        }
        else
        {
            Debug.Log($"There wasn't an active object to DDOL");
        }
        StartCoroutine(LoadSceneNextFrame("Editor"));
        //SceneManager.LoadScene("Editor");
    }
    private IEnumerator LoadSceneNextFrame(string scene)
    {
        yield return null;
        SceneManager.LoadScene(scene);
    }```

[queen saffron]

i just tried the new LoadEditModeScene but 😢

the debug is still fairly printing the game object (cube 0) as previous

Set active object to DDOL Cube 0 (UnityEngine.GameObject)

[dusk apex]

Undo the changes to LoadEditModeScene. Do you've got any scripts that would destroy the cube other than loading a new scene?

[queen saffron]

there is the delete operation but i never used it

using this button "delete"

[dusk apex]

Alright, try simply not loading a new scene and see if the active object (cube) is actually made DDOL

    public void LoadEditModeScene()
    {
        if (GameManager.Instance.activeGameObject != null)
        {
            DontDestroyOnLoad(GameManager.Instance.activeGameObject);
            Debug.Log($"Set active object to DDOL {GameManager.Instance.activeGameObject}");
        }
        else
        {
            Debug.Log($"There wasn't an active object to DDOL");
        }
        //SceneManager.LoadScene("Editor");
    }```

Check the hierarchy to verify

[dusk apex]

It should in the DDOL scene

[queen saffron]

Here

[dusk apex]

So it isn't ever made DDOL

[queen saffron]

it doesn't appear also in hierarchy but it does in the singleton

[dusk apex]

The singleton is simply referencing an object. The object needs to be in the DDOL scene to not be destroyed on loading new scenes.

[dusk apex]

    public void LoadEditModeScene()
    {
        if (GameManager.Instance.activeGameObject != null)
        {
            DontDestroyOnLoad(GameManager.Instance.activeGameObject);
            Debug.Log($"Set active object to DDOL {GameManager.Instance.activeGameObject}", GameManager.Instance.activeGameObject);
        }
        else
        {
            Debug.Log($"There wasn't an active object to DDOL");
        }
        //SceneManager.LoadScene("Editor");
    }```Try this and single click on the log mesasge. Which object in the hierarchy is highlighted?

[queen saffron]

it highlight this object here

[dusk apex]

https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html

Object.DontDestroyOnLoad only works for root GameObjects or components on root GameObjects.

Set it's parent to null before calling ddol (or you may need to redesign some stuff)

[queen saffron]

i see

well thanks to you i would not think about it
really appreciate it

i will modify it accordingly in the morning, i will update you about it
it's nap time haha

the issue about it all that i don't want to destroy objects but keep them all. Even after scene swapping, cause my project is aim to help interior designing using VR and meshs shape manipulation

[dusk apex]

Maybe have Objects (the root scene object) be DDOL and simply have two sets of Meshs: Persistent and Non Persistent
Where you'd manually destroy the children of non persistent on loading a new scene.

[queen saffron]

so storing the game objects between scenes swap is a must, unless i preserve each game object value to the singleton and rebuild each game object upon returning to main scene

[queen saffron]

that could also work i guess. i would need to look into dontdestroyonload and scene manger more about it

glad to know that the whole issue is not about singleton class itself

anyway, really appreciate the help and assistance and thanks for your time.
goodnight!

[tall heath]

Does anyone know if this is a good way of instancing UI materials? I'm thinking it might leave some cache, but overall, is it a good way to do this?

I'm using URP canvas shader graph

[spring basin]

The new material, do you use it only to set the texture?

Or is it a different material?

you could probably try using ProfilePicture.material.mainTexture and flag _texture as your main texture in your shader

you won't have to create a new material

ProfilePicture.material.mainTexture = GetSteamImageAsTexture(ImageID);

[tall heath]

I’m using a canvas shader in URP shader graph, do you know if that still works?

[spring basin]

yea you should be able to mark a texture field in your shader graph as _mainTex

i think its _mainTex? or _mainTexture

[tall heath]

Thank you so much, I’ve been asking around for this, lemme test it

[dawn nebula]

Hmm. I've typically just done new Material(oldMat) and it's worked alright.

Is that improper?

[spring basin]

haven't had a usecase where I needed to create a new material instance

usually i just access the component and its material attached and modify its properties

[tall heath]

It doesn't work, I forgot to tell you but I need it to have different textures but in the same material

So I don't want the pfp to be like this

But instead like this:

[tall heath]

Yeah, I forgot you can do that, I'm gonna switch to that instead of instantiating it

Thanks

But again, by doing this, it does create cache. Is this problem really unavoidable?

[tall heath]

Actually, now that I think about it, by making a new Material based off the old one, it doesn't really create much cache does it? I think I'm actually good with this method. Thanks a lot, it works well.

Thanks for your guy's help!

[vale bridge]

Is there a way to preserve data after modifying a scriptableObject class? Or am I stuck with having to update the SO values every time I make a change to the ScriptableObject class?

Does this mean that people often keep something like a spreadsheet to read into SOs?

[dawn nebula]

I'd imagine it would be the same memory footprint? Not sure. Instantiate is maybe slower to execute. I believe unused Materials are killed during scene reload.

Otherwise you need to keep track of them and destroy when needed.

[vale bridge]

I seem to have done something weird to encounter this problem, I just tried to recreate it but it doesn't do this anymore

[spring basin]

Do you mean, you want to restore the values after you change the fields name or something?

if so, there's a provision for that

[FormerlySerializedAs("oldFieldName")]

[vale bridge]

I figured out why the SO values were wiped, it's becuase I tried to change the same field on different SOs en masse, so what happens is that other than the field (let's say there's A, B and C) that I specify for example C --> then A and B become empty

[sleek bough]

Normally if you want to have mutable data on SO you instantiate it and use that instance, modifying it. When you need to restart you instance original again.

[sleek bough]

Not sure what you are describing there. The only way to wipe the data from instanced SO fields (across all instances) is to rename those fields. If you want to rename the field without erasing data, use https://docs.unity3d.com/ScriptReference/Serialization.FormerlySerializedAsAttribute.html You can remove it later.

[spare island]

I didn't know you can instantiate them

[errant flame]

Hi, I have a simple question,

The application that exports the package we created for the Unity asset store , it asks if it is dependent on any asset store asset, but does it automatically get my dependency on newtonsoft json automatically from the manifest file in the package manager?

Or do I need to add that dependency while uploading my package from somewhere?

[spare island]

I think the point of that package being built in is so you don't have to include it

to avoid every asset that uses it importing it's own version of json

[knotty sun]

when you use the Asset Store Uploader there is a check box 'Dependencies use package manifest' Select that then you can select the package dependencies you want

[errant flame]

@spare island @knotty sun thanks a lot

[faint hornet]

Hey everyone.
quick question about async await.

I am trying to structure a part of my games "style" to have async functionality to perform stylistic behavior and i want these features to be indipentant from the actual game loop.

my question is, is there a way to make sure the regular game logic isn't affected by the async function/s?

[spare island]

you need to be a bit more specific

give an example maybe of what youre trying to do

[faint hornet]

lets keep it simple. so imagine the only game loop thing is just a timer that always needs to be updated regularly. now for the example of the async functionality, clicking the mouse button will begin to trigger async await functions.. lets say 3 seperate, one following the other after completion ( time based ). now how do i ensure that the game clock isn't awaiting the other async functions but only the async functions listen to eachother?

[spare island]

so you want the clock to wait for the task to complete and that task will start another task

[faint hornet]

how do i prevent the clock from 'stopping' during a async function in the background

[faint hornet]

no. exactly the opposite

[spare island]

you want the clock to not wait for the task to complete but wait for the task that the first one starts?

[faint hornet]

give me 1 min. i'll restructure my question for you with better organization.

@spare island

Game loop: constant clock ticking up, and never stops for anything.

OnMouseClick : asyncFunc1 => asyncFunc2 => asyncFunc3;

during mouseclick async functions, game clock is still up-ticking reguardless of async functions executing or not.

^^^ this is the functionality i want. how do i make sure this never fails

[spare island]

why would the clock stop

[faint hornet]

idk, maybe if the game loop becomes more "intertwined" with complexity, it might start affecting some of the game loop functionality since the game loop is indirectly tied to all user behavior. my question is how do i make sure that the async functions never stop game loop functions but only stylistic functions.

[spare island]

are you sure you're not wanting to use coroutines?

[faint hornet]

you make a good point, i guess i'll redirect my question: can i make sure my async functions behave similarly to coroutines?

the reason i don't want to use coroutines is because i will have to chain complex functions together depending on the situation, and async is just a much better option for that.

[cold parrot]

The whole point of async is to not ‚block‘ the other stuff in the game

[spare island]

yep

the problem with async is that it doesn't play well with the unity event loop

[cold parrot]

Unless you do heavy lifting in those tasks nothing will block

[cold parrot]

Why do you say that?

[faint hornet]

yes this is what i'm talking about, the unity event loop sometimes seems to hiccup rarely. idk why. i figured it was because of async, because it's never happened with coroutines

[spare island]

i can't describe exactly why but some things just dont work with async

like debug.logs tend to be completely skipped

[cold parrot]

You’re probably using it wrong then

[faint hornet]

those 'some things' are what i want to fix, without using coroutines. is there a way with async

[spare island]

i'm using it correctly

[hard estuary]

You can still log stuff from async tasks if you make a workaround. So technically yes, it doesn't work, but also yes, it can work.

[cold parrot]

This is so unspecific that there is no way to tell you how to fix ‚those things‘

[faint hornet]

i thought the reason for async is to block presiscly? lol i will only choose async if i want specific things to be blocked temporarily until it's told to do so.

[quartz folio]

by debug logs do you mean exceptions?

[spare island]

no i mean debug logs

[quartz folio]

I have never seen them be skipped in an async method

[spare island]

i had an issue a while ago where i was trying to debug some async functions and for some reason they just never printed

but i found out later that the method was being run the whole time

just the logs weren't printing

[faint hornet]

this has happened to me as well

[spare island]

glad to know im not crazy

[cold parrot]

I smell async void

[hard estuary]

Depends if the async method works on the main thread. For example it works fine for Coroutines.

[quartz folio]

You can also use Debug.Log off the main thread iirc

[mossy snow]

you can

[faint hornet]

is there a way to specify which threads to use?

within the block of code

[spare island]

im wondering if thats what happened

i was way less experienced when i had those issues

[faint hornet]

why would you ever use async void? whats a good example

[mossy snow]

I'd guess you had debug logs (threadsafe) trying to log stuff only available on main thread, which would throw an exception. And if it's in an async void where you aren't catching those exceptions, it would just look like the method didn't work until you removed the logging

[spare island]

probably it

i wonder how many times i used async void

[faint hornet]

lol

[hard estuary]

If it's true, then they probably fixed it. I remember it wasn't working when I coded asynchronous communication between the firebase and the app.

[quartz folio]

async void is likely not a problem, it's not awaiting a Task that is

[faint hornet]

alight guys/girls. goodnight. thanks for the help

[spare island]

i have quite a few async voids

and logs are working in those i believe

[cold parrot]

You know that all these return no handle that unity or the c# runtime can use to terminate or catch exceptions with so they may run forever unless the process is killed?

[spare island]

nope

should they all be tasks

[quartz folio]

You really should be using a cancellation token in almost every async method

and passing the destroyCancellationToken to it at the very least

[cold parrot]

Yes, or at least they should have a try/catch inside that kills them on exceptions and cancellations

[quartz folio]

The exceptions in async void will be captured by Unity—unlike what happens in other .NET applications. It's a fine way to do fire and forget.

[cold parrot]

Best is to never use void

[spare island]

im getting mixed messages

wait so when an exception happens inside of an async function it never gets collected?

[quartz folio]

Example();

...

async void Example() {
  await Task.Yield();
  throw new Exception("Example");
}```

what you need to be worried about is any case where you fail to await a Task

if you do that, then no exceptions will be printed to the console

[spare island]

oh so thats why i was always wrapping everything in try catches

well not everything but the async stuff im running

[quartz folio]

and Anniki is right that any async function will continue to run and unlike coroutines will escape play mode if you don't stop/cancel them

[cold parrot]

You only need to do that for un-awaited async

[spare island]

yeah ive noticed that issue before

i've been manually adding a check to see if the app is still running and stopping the task if it isnt

[quartz folio]

you should use the destroyCancellationToken

and just generally learn how cancellation tokens work

[cold parrot]

You may also want to have a look at UniTask which adds a lot of convenience (light Rx, eliminating/wrapping void, timing control, inline thread switching and non-allocating niceness to some situations among other things)

[spare island]

would it work to use a Task instead?

i'm just wondering because i'm going to have to change every time i used async void

and im going to have to learn what a cancellation token is and how to use it

[cold parrot]

If you use unitask you can wrap all void in a safe handler

[spare island]

im importing it atm

[cold parrot]

Read its docs!

They are quite short

[spare island]

im a bit confused of how to use a cancellationtoken still

for example with LobbyService there is no cancellationtoken argument

I guess i dont understand how im meant to use it fully even looking at the examples

Lobby lobby = await LobbyService.Instance.JoinLobbyByIdAsync(ID);

[craggy pivot]

What the heck? What does -0 mean?

[civic isle]

null means null

[craggy pivot]

Touche

[knotty sun]

the joys of computer math, zero can be positive or negative

just like any other number

[craggy pivot]

I love programming 😍

It probably doesn't interfere with math though right?

[knotty sun]

no not at all

[craggy pivot]

And comparisons?

[knotty sun]

float comparisons should never be for equality anyway, so as long as you dont do that you're ok

[craggy pivot]

Yeah, currently only using < for this variable

[cold parrot]

Make a token source, pass its token into any awaited/async task that supports cancellation. Call cancel on the source when you want to kill the tasks that have the token

[spare island]

wait how would i use multiple cancellation tokens though

[cold parrot]

To support cancellation you typically have to go nothing more but in complex functions or where a task you are awaiting doesn’t support cancellation you check the token manually and throw or return when cancellation is requested

[cold parrot]

Create a cancellation token union source

That allows you to combine tokens

[spare island]

so like put it in a while loop?

[cold parrot]

you should however keep your token sources few

[spare island]

well since i hav ethe power to do so now i'd like to have a timeout for joining a lobby

i'd need a second cancel source for that

[cold parrot]

Yes, but typically you will put it on something like Unitask.Wait which supports cancellation throws

The cancel exception then breaks out of the task

[cold parrot]

depends where you put the timeout. It could be inside the task and use the same cancellation token you have passed into the outter task and respond to it with further internal cancellation/handling

[spare island]

                Lobby lobby;
                lobby = await LobbyService.Instance.JoinLobbyByIdAsync(ID);
                SetLobby(lobby);

so for this how would i wrap this await to wait for it to be done?

[cold parrot]

Does that api not support cancellation/timeout?

[spare island]

theres no parameter for a cancellationtoken

[cold parrot]

What’s does it return?

[spare island]

Task<Unity.Services.Lobbies.Models.Lobby>

something like that

can i just put it in a while loop and check its status

[cold parrot]

No

The result is only available when the task is completed

[spare island]

right so cant i just put a while loop to wait until the Status is equal to 'RanToCompletion'

[cold parrot]

The api supports an options struct

[spare island]

i believe thats for passing things like a password to join but i can check rq

[cold parrot]

Yes, nvm

[spare island]

                Task<Lobby> task = LobbyService.Instance.GetLobbyAsync(ID);
                while (task.IsCompleted == false)
                {
                    if (this.GetCancellationTokenOnDestroy().IsCancellationRequested)
                    {
                        throw new OperationCanceledException();
                    }
                    await Task.Yield();
                }

                if (task.Result != null)
                {
                    SetLobby(task.Result);
                }

it looks like it would work but it also looks stupid

[cold parrot]

Agreed, it also won’t stop a runaway task

[spare island]

this guy came to the same conclusion i did

checking if application is playing

[cold parrot]

Sounds terrible

[spare island]

and then this guy came to the conclusion you did

[cold parrot]

Unitys async APIs aren’t the grandest

[spare island]

im guessing the lobby service must handle cancellation itself

[cold parrot]

Async in unity suffers a lot by loads of legacy event based APIs and defaults to using coroutines. This makes code very ugly

Unitask aims to smooth over those

[spare island]

UniTask doesn't seem to cover the Lobby API

[cold parrot]

Ofc not, unitask is generic and can’t fix bad APIs just incomplete ones

[spare island]

its like im watching history repeat itself

as i go through this year old thread

doesn't seem like theres an official solution to it

[cold parrot]

There is a chance that the api is designed in a way that cancels are unnecessary or undesirable

[spare island]

i dont currently have any strange behavior happening that i think i can attribute to runaway tasks

the game does basically collapse if i load a scene in the wrong order but i think thats just because of how i have it set up

very stronk code

[spare island]

timeouts are built in

i know that

maybe because of the way lobby works its not even possible to cancel it once the request is sent

and ill probably prefer using coroutines to just avoid the mess of async altogether

[cold parrot]

A coroutine wont change the issue though

[spare island]

using them in situations where i can to avoid having to make sure they get destroyed

[spare island]

and like some people said in this thread, im a bit uncomfortable of the idea of trusting this library

at least in terms of support

i will probably go and convert the voids to Unitasks though

[wind meteor]

Good morning everyone, or whatever time it is for you. I created a third person camera script. The rotation works fine, so my next step was implementing camera colission. For that, I used a RayCast that shoots forward out of the camera to the player and checks if there is an object inbewtween. But the RayCast only returns true if there is a whole object in its path. As you can see in the video I added for further clearance, the camera colission works on the thin wall, while working not working on the big cube. I was wondering if there is an alternative to RayCasting that has the same or similar approach. I know CheckSphere etc exist, but there isn't a version that works like RayCast.

[cold parrot]

What concerns are those?

[lean sail]

RayCast only returns true if there is a whole object in its path
The raycast isnt detecting objects that it spawns inside of. You might be able to get around that by temporarily setting this https://docs.unity3d.com/ScriptReference/Physics-queriesHitBackfaces.html buuuut id really just use cinemachine which has everything you're making already built in

[spare island]

mostly future support and reliability

third party repos like this on github are liable to just stop being updated

it is open source which reduces that risk a bit but its still there

[wind meteor]

Do I have to set that Bool true in some kind of game settings or is it enough if I set it true in my script? I set it true in Start() and it doesn't work.

[spare island]

Camera collision is built in to cinemachine

[wind meteor]

Yes I know, but I really would prefer to have done that by myself.

[lean sail]

dont think theres an option for this in the physics settings. You also wouldnt want to just change this setting purely for the sake of the camera, as this affects all physics queries. So you could change it back after doing the cast but still, cinemachine already exists. You could also look into what cinemachine does if for some reason you wanna not use it

[lean sail]

good camera movement really isnt easy, just use it. You'll take weeks longer to create something worse than what already exists, with less options and potential bugs.

[spare island]

'dont re-invent the wheel'

[wind meteor]

Well, you've convinced me. After implementing Cinemachine it's working as it should.

[deft dagger]

hey guys, when i switch my unity editor version i always get this message and i normally press yes but then i start getting gradle build errors when im trying to build, so is there anything i should do ? or is there a fix ?

[cold parrot]

Look into who actually sponsors this repo, this isn’t just a random git repo. Otherwise that’s ofc true. However any software can stop being supported at any moment, including internal ones 🫨 https://www.cygames.co.jp/en/

[jagged plume]

I'm not too fond of the "dont re-invent the wheel" thesis as we do learn quite a lot by re-implementing stuff ourselves

Though yes, it will take a bit more time than if one was to import everything

I mean, going even further in the reasoning, why make games in the first place if similar games already exist

because we like doing

making the stuff

learning about it

having meaning in life through hardship

so yes, do re-invent the wheel

But again, it depends what one cares about

[knotty sun]

I would echo that, know how to do it yourself, then use a library if it fits the use case, at least that way you will know how to fix it when it goes bang

[jagged plume]

yes exactly

and also it makes you aware of functionalities you didn't even know about sometimes

like "oh it does that too?"

[knotty sun]

indeed

[spare island]

maybe if it aint broke don't fix it may apply better

[jagged plume]

well, that's more of a 9 to 5 dealing with legacy code kind of mindset I think lol

But in this case, we are working on greenfields (?)

maybe not ofc

[spare island]

all of unity is legacy code 😭

[jagged plume]

well

ha

[spare island]

honestly a miracle of engineering it works

[knotty sun]

more luck than judgement methinks

[spare island]

seeing as unity barely has an internal game dev team i'd say its probably luck

[jagged plume]

though last time, when I was working on a ParticleSystem, I was really surprised to learn about how you could initialize a variable with a property of the ParticleSystem, and that the initialized variable would "basically" be passed "by reference" (exactly but it's the idea) instead of by value as all variables typically are in C# (?)

[knotty sun]

no, the problem is they dont have an app dev team and never have had

[spare island]

they had one didn't htey?

[knotty sun]

nope

[spare island]

what about Gigaya

[cold parrot]

This isn’t actually the problem, most software companies operate that way and produce sometimes excellent results for users, they however care to observe users in the wild and aim to make a useful product instead of short term shareholder value

[spare island]

yknow, the "triple A quality sample game" they were making https://www.youtube.com/watch?v=-S6J8zm_w1E

and then abruptly cancelled like a year later because they found working in unity too difficult

[cold parrot]

A demo team is pointless for informing anything outside basic UX improvements

[spare island]

sorry it didn't even last FOUR MONTHS

[knotty sun]

Thats a game. Im talking about application development like specifically the Hub and the Editor

[spare island]

ngl unity could use UX improvements

[cold parrot]

Well, depending on your expectations you may think it’s even good enough

it’s not a DCC app like blender

You’re supposed to make the tools yourself in U

Try making any custom tooling in any other engine

[spare island]

unreal

[merry ibex]

yall do you know if theres a way to prevent strings from being stored in globalmetadata with il2cpp enabled?
theres some sensitive strings that I wanna keep secret from being accessed

[spare island]

like what

[jagged plume]

lol

[cold parrot]

Make them in-sensitive

[jagged plume]

What do big teams use then?

Mostly Unreal?

[cold parrot]

Whatever + a truckload of custom tooling

[spare island]

Either unreal or they pay for the fancy version of unity where you can modify the source

[merry ibex]

wdym

[spare island]

well they usually have to modify unreal too
