I have this code which works on submeshes , I want o have blended edges currently they are jagged

These are what the edges look like now

[torpid depot]

guys ı dont know why thıs ıs lıke that happenıng

ı am wrıtıng random.range but always creatıng a library top there and not workıng random.range

this library

ı dont know why doıng thıs Anyone know why

[cosmic rain]

Change it to UnityEngine.Random. Both System and UnityEngine have a class called Random.

It probably resolves to System one by default.

[torpid depot]

this library lıke that

any library not workıng

what ıs the problem wıth that

ı dont know

[dawn nebula]

What's the problem?

[torpid depot]

my library not workıng rıght

[dawn nebula]

What library?

[torpid depot]

when ı want to use random.range class ( already have ın system library) ıt add other library and not workıng

ı am new game devoloper and dont know how can fıx my problem

[lean sail]

you really should clarify more. "Not working" can be said about every problem. look at the #854851968446365696 on how to ask, and this should to be in #💻┃code-beginner since you say you are new.

[torpid depot]

yes but for now focusing thıs problem

[dawn nebula]

So you want to use System.Random instead of Unity's implementation?

[mighty juniper]

Dilch answered you I’m pretty sure. If you want unitys implementation, add using UnityEngine.Random, or alternatively you can just UnityEngine.Random.Range() when you want to use the function

[torpid depot]

just ı want to use random.range wıth default library

because never had a problem wıth that But now dont know what ıs dıfferent

[torpid depot]

look they not usıng that thıng

[dawn nebula]

Ok so you want to use Unity's implementation.

[torpid depot]

ı mean they just wrıts random.range and works

[torpid depot]

what you mean

[dawn nebula]

get rid of this line

[mighty juniper]

Because they aren’t accessing system, you are. It doesn’t know which one to choose so it just defaults to system’s implementation

[dawn nebula]

The issue is that UnityEngine has a class called "Random" and so does System.

[torpid depot]

OWWW ı got ıt

[dawn nebula]

So when you bring in both, and try to write Random, it has no idea which you're referring to.

[torpid depot]

thıs error just for random.range rıght?

ı mean thıs 2 library has random thıng

same tıme

[dawn nebula]

I don't even think that's the default. He explicitly defines Random as coming from System.

[dawn nebula]

No it's going to pop up literally whenever two classes from different namespaces have the same name.

[torpid depot]

so ı need to say ıt Whıch class ı want from

thıs random range

[dawn nebula]

Ok so for a bit more context here.

There are these things called namespaces.

When you write out classes you can specify which namespace they belong under.

Putting code within namespaces is useful because it prevents conflicts.

If you bring in 2 libraries that both have a class called "Event" or whatever, then there'd be a conflict.

Since how is the program supposed to know which Event class you're referring to?

[torpid depot]

ı undurstand what u mean

so can ı use thıs namespace thıng for all thıs classes?

[dawn nebula]

UnityEngine is a namespace that contains a lot of the basic Unity classes.

System is a namespace that contains a lot of the basic C# utilities.

They both have a class called Random.

[torpid depot]

can ı put unıtyengıne and system namespaces ın same namespace?

for fıx that error

[dawn nebula]

No namespaces are separate.

[fervent furnace]

You cant, they are not created by you

[torpid depot]

so namespaces are constant thıngs

cant be fıxed or change

[dawn nebula]

What you need to do is get rid of these 2 lines.

This'll get rid of the conflict.

Since it'll only bring in the Random class from UnityEngine.

[fervent furnace]

You are using the namespace, if they contains some classes that have same name, you need to specify which class to use

[torpid depot]

ı got a questıon Is unıtyengıne have all c# code class

[dawn nebula]

It has code related to Unity.

[torpid depot]

when ı delete system namespace my c# cods can work?

[torpid depot]

ı undurstand

[dawn nebula]

Ya System contains a lot of utility stuff but it isn't required for like... c# to work.

[torpid depot]

when ı delete system after some cods Maybe ı need some utılıty ın system library

is that possiblke?

possible?

[fervent furnace]

Yes, by specify the class to be System.class if you didnt using their namespace

But you dont want that so just using System

[torpid depot]

but thıs tıme that have error because have same class wıth unıtyengıne namespace...

[dawn nebula]

So if you need stuff from both UnityEngine and System, and there's a name conflict (like you get with Randm) you can write the namespace name BEFORE the class name in the code itself.

System.Random will refer to the Random class in System.
UnityEngine.Random will refer to the Random class in UnityEngine.

[torpid depot]

yes ı dıd that just tryıng to fınd any other way but It ıs okay

ty guys btw <3

@dawn nebula u not Lazy lıke your name btw

u so smart xd

ty

[dawn nebula]

no problem

[ocean hollow]

this question would be better in #archived-networking

[eager creek]

Ok

[old linden]

I'm working with newtonsoft Json here. How can I return this list with the underlying values? It seems to return the data type

[mighty juniper]

Hey all, I'm trying to create my own object pooling in unity, and in order to reference different pools I have a dictionary containing the GameObject of the pool i want, and the Pool class itself. However, when trying to run my GetPooledObjects() function from an external script, passing in an instance of the same GameObject in the pool, it logs the warning. Heres the function:

    public void RePoolObject(GameObject obj)
    {
        if (!poolsDict.ContainsKey(obj))
        {
            Debug.LogWarning("Pools Dict does not contain the prafab that is being repooled");
            return;
        };

        poolsDict[obj].RePool(obj);        
    }}```

And here's where im trying to repool it (This is inside of a script of a projectile from the pool)
```cs
    private void OnTriggerExit2D(Collider2D other)
    { // Pool projectile when out of map
        if (other.gameObject.CompareTag("Boundary"))
        
            ObjectPool.instance.RePoolObject(gameObject);
        }
    }```

If anyone knows why it's failing that would be greatly appreciated

[soft shard]

I have never seen a list set like that, though in your for-loop you are logging your entire list object instead of an element from it, maybe you want items[i]

[old linden]

Yep just spotted it. Rookie error haha. Thanks anyway

[copper grove]

im here i need to do so that on the spawncoords if the texture is GroundTexture execute a code.How do i do so

[wide dock]

A prefab is not the same thing as an instance of a prefab

Use something else for the key

Or use the object pooler provided by Unity

[upper pilot]

How can I block OnMouseEnter event from firing on my 2d sprite with UI element?
Currently I can click through UI on a 2d sprite and fire OnMouseEnter event.

[copper grove]

will someone help me plss

[mighty juniper]

What would you recommend I use for the key?

[knotty sun]

https://forum.unity.com/threads/detecting-terrain-texture-at-position.94723/

[copper grove]

thank you savior 😄

[wide dock]

Anything that isn't tied to a specific instance but rather to every object of the same type

[mighty juniper]

Gotcha thanks

[dense crow]

wwhy instance in unity work when it's component is disabled ?

here it is

i disabled the singleton component but it still work

[quartz folio]

Why would it not? https://docs.unity3d.com/ScriptReference/MonoBehaviour.Awake.html

[dense crow]

oh i got it , ty so much

disable the object give another result . i am a little bit confused here. are disable component and object different ?

[plucky inlet]

Hey everyone, I am currently testing out the visionOS Package with the simulator. I was reading on reddit about the simulator being able to tracke the cameras position with the tracked pose driver, but unfortunately, the position does not seem to update and accessing the transform.position just returns the start position. this might be an issue with me using the play to device feature. Did anyone else test it out and was probably able to get the code part of the actual position of the tracked pose driver? Or should it just be .transform.position and using "play to device" is just not working in this case.

[thick terrace]

yes, the enabled flag on a component just stops its Start/Update etc methods from running

[gusty aurora]

I have a simple behaviour, when my character walks into an enemy, the enemy pushed him away. But if my character dashes into an enemy, then he kills the enemy. Would you put all that logic onto the character, or onto the enemy, or a bit on both ?

[hard viper]

a bit on both

depending on how unique the behaviour is determines if it should be on the player or enemy. if only 2 out of 20 enemy types behave like this, then on the enemy

either way, both enemy and player need a script on them that exposes player state and enemy vulnerabilities, so that your script can do the logic

[mighty juniper]

Hey all, I'm trying to access a GameObject's script, however am running into some issues.
Inside of the script i have a variable that references the script i am setting it up from. I'm trying to run the function MoveToPlanet(), which relies on that variable being set. However when trying to do so it gives me the usual Object reference not set to instance... error. Despite calling the function after setting it, does anyone know what i may be doing wrong? (The reason i cant run it on Start() is because these are pooled objects). Thanks

        Enemy enemyScript = enemy.GetComponent<Enemy>();
        enemyScript.GameController = this;
        enemyScript.MoveToPlanet();```

[somber nacelle]

what line is the null reference exception actually on? if it is the first one you've shown then enemy is null. otherwise you need to look at where the error is actually coming from

[fresh cosmos]

should i use if(myScene == new Scene()) or compare against an existing empty scene to check that a scene has nothing in it?

[knotty sun]

try scene.rootCount == 0

[thin aurora]

Scene has no logic when it comes to comparison so neither would work

Instead actually check if it's empty

Actually, scenes are compared with a handle. Idk what that handle is though

Maybe an id, in which case it would also not work

https://github.com/Unity-Technologies/UnityCsReference/blob/master/Runtime/Export/SceneManager/Scene.cs#L112

[fresh cosmos]

ok, thanku. so then this should work ?

// ... 

Scene myScene = new Scene();

// ... logic to find a scene

if(myScene.rootCount == 0)
  // something

[knotty sun]

not sure why you want the new Scene() in there at all

[fresh cosmos]

it cant be null so it needs to be something. or at least thats an error im getting

[knotty sun]

it can be null

[thin aurora]

You want to check if a scene is empty, right? Why instantiate a new scene that is guaranteed to be empty?

[fresh cosmos]

Cannot convert null to 'Scene' because it is a non-nullable value type [MultiSceneTools]csharp(CS0037) is the error

[thin aurora]

Because Scene is a struct

What exactly is the point of this code? You're making no sense with what you're sharing

Why check rootCount is a Scene instance you created manually?

[fresh cosmos]

i guess i should then rethink what im doing

i was just trying to make a method to avoid copying the same code

[thin aurora]

Structs are value types so instead of null you'd use default, which is basically the same as what you do now

Structs are expected to implement a sort of comparison so you can compare against default, but again I have no idea what this handle is in the scene and I doubt it's the correct way in general

[fresh cosmos]

ah, i didnt know i could use default like that

[thin aurora]

To make it nullable, change Scene myScene = new Scene(); to Scene? myScene = null or Nullable<Scene> myScene = null

[fresh cosmos]

well since im making a method to shorten code elsewhere i wanted the method to be like bool SceneIsLoaded(string name, out Scene FoundScene) which would require me to define FoundScene

[thin aurora]

Then just return default as the out parameter and return false from the method

Generally the out-parameter is not expected to make sense if the method returns false

[fresh cosmos]

exactly

[thin aurora]

Also, methods like these always start with Try, to indicate it tries to do something, and will return a boolean indicating success, alongside out parameters for any additional results

https://learn.microsoft.com/en-us/dotnet/standard/design-guidelines/exceptions-and-performance#try-parse-pattern

What exactly is wrong with this method though? https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.GetSceneByName.html

[fresh cosmos]

this fixed it. it was just the out parameter that wasnt right

[velvet nest]

Does anyone have a handy way of drawing an oblique/skewed frustum via Gizmos in unity? I've tried searching everywhere online for it but Google isn't being very helpful :/
The default Gizmos.DrawFrustum() function won't work here since it draws a regular "straight" perspective frustum, and all I've got is a projection matrix with some near/far values and a camera position/orientation. I've tried using the Gizmos.matrix to convert a regular wire cube from clip-space into world space, but with no real results (which I don't understand, as the reverse projection process ought to just be worldToCamera * projection.inverse as far as I know)

[static matrix]

any ideas on how I can get a wall-crawling enemy? like tiktiks and hollow knight
I can do inner corners fine but im not sure how to do outer corners

[fathom patrol]

Hi there! I'm in a small team of students currently developing a game that is inspired by jackbox. To allow us freedom with phone screens and input, we host a WebGL application on our server, and want to connect this to some sort of host computer via a server. Is mirror the best option here?

Both exports come from the same initial Unity file and mirror is installed. How do we bridge this connection over our server so it can be played from anywhere instead of just localhost?

For more context, we have WebGL and the standalone application working, and it can connect through localhost. The only issue is that without using localhost it does not work. The server successfully listens on 7777 (we think) but when using WebGL it should also listen for 7778 if I have to believe the documentation.

[static matrix]

this is an issue with networking
not being able to access outside of localhost is a common issue

you could find a tunneling service like bore

but i've only ever used bore for minecraft servers and never for sites

https://github.com/ekzhang/bore

[solemn raven]

hey
is SceneManager.LoadSceneAsync(2); would also unload the current scene ? or do I need to manually unload it ?

[thin aurora]

If the scene is additive it must be manually unloaded

PlayOneShot creates a temporary separate audio source to play the clip. Naturally the things you're checking aren't going to work in that case.

[opal ivy]

Making an FPS game at the moment. Looking for devs who are more experienced than me to provide some input on how I should approach this system?

[leaden ice]

An array of Bullets

with an int currentBulletIndex;

[opal ivy]

Do you think having a Queue would help as well? The Queue could store the current ammo type as an int and it would go in order as the queue gets cleared?

[leaden ice]

no I don't think a queue would help

it would complicate things

A simple array is better.

[opal ivy]

Fair. But later on down the road, I want the ability for the player to be able to put whichever ammo in whichever chamber, so initially I was thinking a combination of Queue and a List/Array would be best

[leaden ice]

think:

Fire() {
  Bullet b = bullets[currentBulletIndex];
  if (b == null) {
    // CLick! Empty chamber
  }
  else {
    b.HandleFiring();
  }

  currentBulletIndex = [currentBulletIndex + 1] % ammoCapacity;
}```

[leaden ice]

I don't see how that changes anything

that's handled by the bullet part

the gun just fires whatevers in it

[opal ivy]

gotcha

[leaden ice]

an Array is best suited here since you have a fixed number of chambers in the revolver

[thin aurora]

A queue would be much easier

[leaden ice]

how would a queue be easier?

you'd have to enqueue empties

[thin aurora]

You don't fire a different bullet out of order

[leaden ice]

how does an array make things fire out of order

that's what the currentBulletIndex is for

[thin aurora]

I'm saying if you keep an order like this you might aswell just use a queue

[leaden ice]

I don't see how it's simpler at all

explain

[thin aurora]

Shoot three bullets, enqueue three more bullets

[leaden ice]

what benefit is there

[thin aurora]

Much easier than having an array

[leaden ice]

how?

[thin aurora]

I don't understand how my example is not clear enough

[leaden ice]

the size of a queue changes

it doesn't fit the model at all

when you fire a bullet you need to enqueue an empty

[thin aurora]

Exactly

[leaden ice]

if you keep shooting without replacing, you need it to not fire anything

that's weird

[thin aurora]

And then the next entry is the next bullet

[leaden ice]

This is pretty much all the code you need with the array

[thin aurora]

And a queue can be a static size

[leaden ice]

except reloading

[leaden ice]

it can't be

it changes size every time you call Dequeue and Enqueue

it's just not the right model

[fervent furnace]

queue doesnt support random access

[leaden ice]

with a revolver you can put a bullet in any chamber

and leave any chamber empty

[fervent furnace]

=you cant insert bullet at random position

[leaden ice]

that's incredibly awkward with a Queue

[thin aurora]

You're not inserting the bullets in a random position

[leaden ice]

With the queue:

• I fire a bullet. You say now Enqueue(null) I guess?
• now how do I replace that null with an actual bullet? (reload)

i have to now dequeue the null

and enqueue a bullet

and probably rebuild the whole queue because that happens out of order

it's totally messed up

[thin aurora]

That's not how a queue works

It doesn't replace it with null

[leaden ice]

Not putting nulls in the queue would not work the way a revolver works

when you have an empty chamber and you pull the trigger, it does an empty click and rotates again

so you must put nulls in to maintain the realistic behavior of the revolver

[thin aurora]

Actually, let me correct myself. It does insert null.

Enqueueing a bullet will replace the first null value

[leaden ice]

how?

[thin aurora]

https://github.com/microsoft/referencesource/blob/master/mscorlib/system/collections/queue.cs#L161
https://github.com/microsoft/referencesource/blob/master/mscorlib/system/collections/queue.cs#L186

[leaden ice]

How would you replace a null. Queue doesn't have a "replace" function

[thin aurora]

The queue does that

[leaden ice]

it definitely does not

[thin aurora]

Check the code. A queue keeps track of the last valid item and replaces the null value by index

[opal ivy]

My initial Idea with the Queue system is that the player would be able to change which ammo would go where when they reloaded in a menu (As in a pre-made selection of ammo that could be interchanged) would be when you reload, it queues up 6 of the corresponding chambers with ammo types as integers. The integers could then be referenced to do the corresponding type of shot it would make

[thin aurora]

Either way unless this game reloads bullets in random positions it doesn't make sense to not just use a queue

An array also works but why write extra code when a queue does the exact thing asked

[leaden ice]

This is exactly why you'd use an array

manipulating individual indices in a queue is messy

[thin aurora]

A better system might even be a stack since you probably reload the opposite way

[leaden ice]

Disagree strongly. The queue is the one that will require a lot of extra code here.

The only thing a queue gets us here is a strong ordering of the chambers. The array gets us that too with very little fuss.

[fervent furnace]

once you need random access, the only choices left is array

and you implement your own stack/queue by copying the code and add the indexer....

[leaden ice]

If you have a queue with this:
[FireBullet, empty, IceBullet, empty, empty, RegularBullet]
God it will be really fucking annoying to go through this queue and replace empties

with an array it's really simple

With the queue you absolutely can't do it without dequeueing and requeieing basically everything

it's that simple people

Just think about it for a minute and you'll see an array is the simplest approach here by far.

[thin aurora]

A queue literally can't do this unless you manually insert "empty"

[leaden ice]

You HAVE TO

[thin aurora]

It's not skipping indexes

[leaden ice]

if you want revolver behavior

you must insert empties

otherwise it's not a revolver at all

[thin aurora]

Yeah if we're going to add a whole list of "what ifs" to this question then I'm sure arrays eventually are a better choice

But this was never asked

[hexed oak]

Is there an event I can listen for in any type of renderer that could tell me when the material has changed?

[leaden ice]

I'm don't see how it's a what-if. They specifically asked for revolver behavior

[opal ivy]

Live reaction atm:

[leaden ice]

with pictures and everything

[leaden ice]

They even provided a black circle here proving they want to support empty chambers

[thin aurora]

Boy I wonder what feature would allow me to take the first entry of a collection and update it

[leaden ice]

it's a requirement

[thin aurora]

No, you argue because you assume this solution needs a million edge cases that might be added

[leaden ice]

wjhatever

go with the queue

it will not work

and they'll be back lol

just try it, it won't work like a revolver

[opal ivy]

The way it would work is it fires chambers 1-6 in that order, and then it reloads the player's selected order that was made in the menu all at once (Speed loader esque)

[leaden ice]

yes I know how it will work

you need an array

a queue will not do what you want.

But if you are in love with a queue feel free to try it and see that for yourself.

[opal ivy]

just making sure I have all the ground here for how it will function covered

[hexed oak]

Could a linked list work, of size magazine size (6)--a queue kind of assumes a starting point, but a revolver allows you to start from any given node

[fervent furnace]

an array for fixed-size magazine is better, then you maintain a current pointer indicate the next round, as PreatorBlue said

[leaden ice]

If you only allow firing ALL bullets. and ONLY allow reloading ALL bullets, then a queue will work If you want any kind of behavior that involves:

• Allowing the player to try to fire empty chambes and getting "click"
• Allowing reload before firing all bullets, while keeping some of the previous bullets loaded

You will need a queue

[leaden ice]

it could but again why? You would need to insert empties. An array is a fixed size (just like a revolver) and will do the same thing faster, with less fuss.

the "looping" behavior is like the least important/least difficult speedbump here

[hexed oak]

sometimes the trivial solution is the best

anyways, by chance is there an event I can listen for in any type of renderer that could tell me when the material has changed?

[leaden ice]

There is not

[chilly surge]

If you want to model a revolver that's fixed sized, using a fixed sized data structure seems like the straight forward logical choice if you ask me.

[leaden ice]

Can't you make your own event when you change the material?

[opal ivy]

Thanks for the input though guys, I'll make a copy of the project and I'll attempt an array in one copy after a bit of research and I'll attempt a queue build in the other and see what works best

[hexed oak]

It's being changed via animation, so I'd have to keyframe it

[fervent furnace]

https://en.wikipedia.org/wiki/Circular_buffer

[hexed oak]

dealing with adding hundreds of keyframes possibly

^ similar to the circularly linked list

[hard viper]

or, hear me out, an array

you should know exactly how many keyframes you have when you initialize

[leaden ice]

The circular buffer implementation is just an array, even in that article

But yeah this is a good article for @opal ivy to look at.

Because a revolver is a perfect example of a circular buffer

[topaz hill]

what i should do with it tho?

idk how to usse it

[somber nacelle]

read the bot message on how to correctly share code

[cedar jolt]

Hey !

I am trying to make a chess game using Netcode. For the players, I currently have a gameobject that only have a camera at a certain angle. I want to rotate that object for each new player so they face each other in a 3d world. In this code, I don't see the "player.transform.Rotate(0, rotationY, 0, Space.Self);" doing anything.

foreach (ulong clientID in clientsCompleted) {
    
    GameObject player = Instantiate(playerObject, new Vector3(0,0,0), Quaternion.identity);

    player.transform.Rotate(0, rotationY, 0, Space.Self);

    player.GetComponent<NetworkObject>().SpawnAsPlayerObject(clientID, true);

    rotationY += 180;
}

[topaz hill]

here is the code i am using its basically i have a particle that expands over time when there's a input along with it a sphere collider also expands the same way and i want to detect certain objects as the sphere grows but for some reason its not working at all

https://gdl.space/natacofoqi.cs

[thin aurora]

What is not working? OnTriggerEnter?

[topaz hill]

yes

[thin aurora]

Does it call the method at all?

[somber nacelle]

https://unity.huh.how/physics-messages

[thin aurora]

Try placing a debug message in it to validate

[somber nacelle]

also don't compare tags using string equality, use the CompareTag method instead

[topaz hill]

ok

[topaz hill]

ok

[topaz hill]

no its not calling the OnTriggerEnter

[topaz hill]

still not working as intended

[somber nacelle]

have you confirmed that OnTriggerEnter is being called?

hint: the link i sent shows you how to ensure it is

[topaz hill]

yea i confirmed its not being called

[somber nacelle]

so let me guess, you didn't bother going through the steps to troubleshoot why it isn't?
and you expect someone to walk you through those steps to check for you?

[merry sierra]

public void OnVertical(InputAction.CallbackContext ctx) => moveDummy = ctx.ReadValue<float>();

if(isPC)
        {
            if (!isReseting && canControl)
            {
                dynamicMoveInput = moveDummy == 0 ? 0 : Mathf.Sign(moveDummy);
                //moveInput = forwardFakeInput;
                turnInput = turnDummy == 0 ? 0 : Mathf.Sign(turnDummy);
            }
        }
        else
        {
            /*if (!isReseting && canControl)
            {
                moveInput = moveMovement.y;
                turnInput = turnMovement.x;
            }*/
        }

        moveInput = Mathf.Lerp(moveInput, dynamicMoveInput, Time.deltaTime * moveLerpSpeed);

do anyone know what is wrong with this code

[thin aurora]

Then consider checking this link #archived-code-general message

Not much we can do

[merry sierra]

move input value coming as NaN

[topaz hill]

no i tried to resolve it

[thin aurora]

Show all the code, including your definition of moveInput and everything around it

[somber nacelle]

how

[topaz hill]

searching online for how these triggers work reasons for wht they wont work

[somber nacelle]

oh my god click the fucking link i sent already and go through the steps

[topaz hill]

i did

[somber nacelle]

then go through the troubleshooting steps to figure out why OnTriggerEnter is not being called. because those are the correct steps to take and if you have confirmed everything is correct according to those steps provided then it will be called

[mighty juniper]

Hey all, I'm working on object pooling and i was wondering one thing. I want to treat my scripts on the objects like they have just been created every time I want to grab one from the pool, how should i go about doing this?

[thin aurora]

Grab from the pool and add the script after that, I guess

[somber nacelle]

create a method on the component that your object pool will call that will do all the re-initialization

[merry sierra]

@thin aurora https://paste.ofcode.org/qgjW6x4fYQSgeRjiMCQDM

[mighty juniper]

Would require redoing a lot of what i've done already i think unfortunately, and would just make the problem more complicated than manually resetting

[mighty juniper]

Thats what i was thinking initally thanks just wondered if there was a better way

[thin aurora]

And what is displaying it as NaN?

[merry sierra]

moveinput

[thin aurora]

But what displays it like this

[merry sierra]

lemme record a video

[thin aurora]

Thank you

[merry sierra]

it was working if i replace dynamicmoveinput to moveinput on line 96 and remove line 110

[somber nacelle]

scroll all the way up to the first error in the console, click it and see where that error is actually coming from

[topaz hill]

bro i still dont understand after checking through all steps its not working properly

[somber nacelle]

show both objects involved in the trigger enter

[ocean peak]

hey there, i dont know if im posting in the right section but hey here we go.
I m trying to work with the ui toolkit TreeView to make a simple file explorer,
I wanted to know if and how it was possible to lazy load the tree hierarchy, by using Lazy<T> for exemple or at least dynamically load the subfolders and such
but the id system makes it kind of hard
I ve been searching but it seems like i m going in circles

[topaz hill]

i didnt get it wdym

[somber nacelle]

i mean for you to show the inspector of both objects involved in the overlap of one collider with the trigger collider that you are expecting to produce an OnTriggerEnter message

[mighty juniper]

        GameObject enemy = ObjectPool.Instance.GetPooledObject(prefab);
        Enemy enemyScript = enemy.GetComponent<Enemy>();

        enemyScript.ResetState(position ?? GetPositionOnBorder());

//Enemy class
    public void ResetState(Vector2 newPosition)
    {
        transform.position = newPosition;
        health = initialHealth;

        MoveToPlanet();
    }```

Trying to make the method like you said but the issue is for some reason im getting the usual "Object reference not set to ...." error, despite getting the component, any idea why?

[somber nacelle]

then it does not have an Enemy component

assuming that the error is actually coming from the line you call ResetState on

[mighty juniper]

Oh maybe it's because some of my scripts inherit from Enemy rather than directly being Enemy, but i've done that in the past and I swear it's worked

Yeah it's coming from .ResetState() line

[somber nacelle]

that would work

[topaz hill]

1st image is the first object 2nd image the 2nd component

[somber nacelle]

then whatever object is being returned from the pool does not have a component on it that derives from Enemy

[somber nacelle]

and where is the rigidbody

[mighty juniper]

Alright i'll do some more digging and get back to you thanks

[topaz hill]

in first object its there and added but in secnd itsw not there

[somber nacelle]

show it

[somber nacelle]

and what layer are both of these objects on

[merry sierra]

every thing is breaking because move input turning as NaN not sure why its happening i an lerping the moveinput correctly

[topaz hill]

both on same layer

[somber nacelle]

and can that layer collide with itself in the layer collision matrix?

[gaunt sparrow]

is there s help channel here?

[topaz hill]

yes

[somber nacelle]

!support 👇

[tawny elk]

Where can I get help?

Take a look at #🔎┃find-a-channel

:warning: This is not a channel for official support.

Please do not ping admins, moderators, or staff with Unity issues.

[somber nacelle]

and how are you moving both objects

[topaz hill]

1st object has a player controller script and the 2nd object is the child of 1st object so it moves together

[somber nacelle]

ah yes, a player controller script. i am certainly familiar with your code base so i know exactly how that moves the object

but of course if they are part of the same object then their colliders are part of the same compound collider for the rigidbody

[mighty juniper]

This is what is being returned from that function, and as you can see it 100% has an "Enemy" script. As seen in the second image it definitely is getting returned correctly too. And enemyScript is found, so i have no clue why

[topaz hill]

sorry bro i am sending it if u had a bad day and i amtoubling u sorry

[somber nacelle]

show the actual stack trace for your error then

[topaz hill]

i quite didnt get it what should i do
here player controller script https://gdl.space/asotetojeb.cs

[somber nacelle]

why do you have both a rigidbody and a CharacterController on the same object?

[merry sierra]

is there a way i can make my float upto two digits

[mighty juniper]

Wait a minute, the error points to a different script, accessing my GameController singleton, it just conveniently happened to be on a line that made sense, i didnt read it enough. Even so though, i'm not sure why its doing that.

This is the line:

Vector2 destination = GameController.Instance.planetTransform.position;

and this is how im managing the singleton in GameController

    public static GameController Instance { get; private set; }

    private void Awake()
    {
        if(Instance == null) Instance = this;
        else
        {
            Debug.LogWarning("Duplicate GameController instances");
            Destroy(this);
        }
    }```

[dim spindle]

Im sure it's fine, lots of people here constantly deal with people asking questions and not giving all the information, I guess they either get annoyed or like to make lots of sarcastic jokes about it lol

[topaz hill]

i thought of having a compound player controller so tht it will be easir for physics interaction with other objects

[somber nacelle]

yeah those two components do not mix

[topaz hill]

ik but i got it to work

[somber nacelle]

did you though

[topaz hill]

and it works fine

[topaz hill]

yes

[worldly ruin]

Hi is there a way to use Unity Collab on Unity 5.6 please? Or does anyone have any alternatives for live coding with other people? The device i want to port my game to only supports this version of the Unity Editor :/

[somber nacelle]

well then i guess your issue is resolved! congrats

[topaz hill]

i mean i got the compound controller to work

the trigger thing is still unresolved

[somber nacelle]

collab is dead. unity version control exists but i highly doubt that the package that supports it is available on 5.6 (especially since that version doesn't even have a package manager)
just use git

[lean sail]

Github

[somber nacelle]

or use a modern unity version without pirating nintendo's SDKs

[worldly ruin]

Github doesn't really allow live editing, if someone pushes a commit while someone is editing something then they would have to copy their progress to the new code

[ocean hollow]

myFloat.ToString("F2");

[somber nacelle]

yeah for a number of reasons. one being that it is a child of the collider and part of the same compound collider used by the rigidbody so why would the rigidbody think it is colliding with a different body?
second, you aren't moving the rigidbody via physics anyway so that component is pointless.
third, this should just be a physics query using an OverlapSphere rather than relying on physics messages
fourth, i already pointed out that rb and cc don't mix

[merry sierra]

not string but a variable

[worldly ruin]

does Git allow live editing ?

[mighty juniper]

anyone know?

[somber nacelle]

no but neither does collab or UVC

[ocean hollow]

Why can't you convert it to a string?

[worldly ruin]

mh. I'll try searching for something else then

[topaz hill]

oh thanks man u helped even though u got annoyed by me and sorry for not giving complete intell on issues

[dim spindle]

Some rounding function lets you do that im sure

[somber nacelle]

why do you need live editing in the first place? there are no good source control services that support this

[merry sierra]

i need that variable i think i am getting an infinte number because there are lot of numbers after decimals

[somber nacelle]

that doesn't make any sense

[worldly ruin]

I want people to work with me on my project at the same time, basically

[ocean hollow]

There is no such thing as an infinite number

A float has a specific amount of digits

[lean sail]

Maybe you should look into how version control works in the first place, git is your best friend. You arent gonna find (or want) a google docs version of coding. This would be shit

[merry sierra]

like its showing as NaN

moveInput *= moveInput > 0 ? fwdSpeed : revSpeed;

fwd speed is 50000

and moveinput before is 0.9999999999 something

[somber nacelle]

are you certain this is the line causing the issue?

[merry sierra]

yes

[worldly ruin]

ok i see, i'm gonna search about that. Thanks a lot!

[somber nacelle]

the only way that line could cause moveInput to be NaN was if it was already NaN or the number you multiply it by is NaN

in other words, your issue lies elsewhere

[merry sierra]

so i changed the fwd and rev by 1 and 1 now its giving output but if i undo it NAN

[somber nacelle]

then one or both of those values is NaN. so you need to look at where those values come from

[merry sierra]

those are value that just put in inspector and those value never change

[somber nacelle]

show the code. and the stack trace for the first error in the console

[merry sierra]

rigidbody.force assign attempt for 'Motor' is not valid. Input force is { NaN, NaN, Infinity }.
UnityEngine.Rigidbody:AddForce (UnityEngine.Vector3,UnityEngine.ForceMode)
CarMovementComponent:FixedUpdate () (at Assets/Game/Scripts/Car/CarMovementComponent.cs:166)

@somber nacelle see this

[somber nacelle]

okay so all of the variables involved in these calculations are public which means any other object can change them at any time so start by making sure that none of them are being modified by other objects anywhere

[solemn raven]

Thanks ❤️

[somber nacelle]

and also print some more useful information rather than just spamming the value with no context to the console

[merry sierra]

so move input is multipling by itself with fwdspeed which is 50000 so i think its is going beyond the bounds of float (like the max float can carry)

[somber nacelle]

why are your numbers so huge anyway

[ocean hollow]

If your player is so big compared to world space that you have to make your numbers huge in your movement script, you might encounter floating point errors from unity itself

[merry sierra]

player is small only i think but as i put mass and stuff like to 200 it needs 50000 force power to move properly

[somber nacelle]

then don't put the mass and stuff that high

[dawn nebula]

What do you guys use when you need to execute code sequentially? Aka do X until Y, then do Z until W, then A until B. Enumerator? (Like not through Unity, just raw enumerators).

[merry sierra]

anything i put above 1 is going NaN

in fwd or rev speed

maybe issue is something else

[somber nacelle]

i mean, if you just continuously increase it forever without capping it then yeah eventually it will hit the limit that a float can store

[leaden ice]

Code always executes sequentially

[dawn nebula]

Over many frames I mean.

[leaden ice]

Kind of sounds like you are asking about a state machine

Coroutines and async are just lightweight state machines

[brave canopy]

What to do if I have a scene in Unity Editor opens quickly and without errors, but in the build either takes a very long time to load or does not load and gives the error Connection lost. OnStatusChanged to DisconnectByServerTimeout. Client state was: Leaving. SCS v0 UDP SocketErrorCode: 0 AppOutOfFocusRecent WinSock.I use Photon for multiplayer.The scene is loaded via Photon.Loadleve().

[long hare]

can some one help scroll up to see the issue

[ocean hollow]

this is a #archived-networking question

[brave canopy]

Hmm. Will I ever get an answer there?

[lunar python]

actually the float might just overflow and resets

idk if that applies to c#

but theres a hash algorithm with integer overflow

[heady iris]

Show your code.

that number is being multiplied by 10,000 every frame

[somber nacelle]

the issue is that they are not capping the value at all, so it reaches infinity

[heady iris]

right, but even just applying an absurd force wouldn't make a value incrase exponentially

you'd have to be applying an absurd force that's also proportional to the current velocity

[somber nacelle]

they are multiplying their force by like 50000 or some absurd number each frame

[heady iris]

rb.AddForce(rb.velocity);

[heady iris]

The easiest option is to use a Coroutine. https://docs.unity3d.com/Manual/Coroutines.html

[heady iris]

this would also explain why they need such extreme values to make the character start moving

[dawn nebula]

Ya I know. More so asking outside of a Unity context.

[somber nacelle]

dunno why they deleted the message with the link to their code, but they have this moveInput variable that they just multiply by a big ass number without ever reducing its value or clamping it 🤷‍♂️
and it all came about because they are using extreme numbers for their mass and likely drag too

[heady iris]

well, the thing is that a unity coroutine is "just an enumerator"

in fact, I've done my own coroutines at least once

I needed very specific control over when the enumerator had MoveNext() called on it

[dawn nebula]

So the answer is... just use an Enumerator and iterate over it?

[heady iris]

Right. That's all that Unity is doing, plus or minus the special types you can yield (e.g. WaitForSeconds)

myFakeCoroutines.RemoveAll(x => !x.MoveNext());

that's literally all I do, actually

ironically, I wound up using these "coroutines" to prevent two "coroutines" from running at the same time

...so that list is a bit pointless now

[heady iris]

I was doing work that needed to happen after the FinalIK package did its work

this is somewhere late in LateUpdate

the best I could do with Unity coroutines was WaitForEndOfFrame, but that's a bit weird -- if you don't have the game view open, that never actually happens

it was also conceptually wrong; I wanted to do work before rendering

so I wrote a method that's called after all of the IK systems signal that they're done running

it's a late LateUpdate!

[heady iris]

ah, that would also do the trick

[stone ginkgo]

i'm trying to make a paper mario-style flip using thje y rotation in my game, byut when i use this code, the sprite's y rotation only changes by about 1 degrees, why is that?

        if (isFacingRight)
        {
            for (var i = 0; i < 1800; i++)
            {
                transform.Rotate(0.0f, transform.rotation.y - 0.1f, 0.0f, Space.World);
            }
        }
        else
        {
            for (var i = 0; i < 1800; i++)
            {
                transform.Rotate(0.0f, transform.rotation.y + 0.1f, 0.0f, Space.World);
            }

        }

        flipping = false;
        isFacingRight = !isFacingRight;

[knotty sun]

because you are using a Quaternion as if it was an Euler

[stone ginkgo]

idk what either of those are lol, what should i do instead ?

[leaden ice]

transform.Rotate(0, 180, 0) to rotate something 180 degrees

[heady iris]

Quaternion.x is not an X euler angle.

[knotty sun]

well do some research. look at transform.rotation

[heady iris]

(exposing it was a mistake)

it's part of a vector that's used to represent the actual rotation

https://docs.unity3d.com/ScriptReference/Quaternion-eulerAngles.html

this page describes what's going on

[stone ginkgo]

yes but i want it to be a smooth rotation

[unkempt zenith]

I would use a tween then

There are many libraries for that

[leaden ice]

then you need to do it over time

either way

you rotate 180 degrees

not whatever witchcraft formula you have there

[stone ginkgo]

but tht instantly changes the rotation

[leaden ice]

so does your code

just by the completely wrong amount

if you want to do something over time you need to use Update or a Coroutine

otherwise you're doing all your stuff within a single frame

aka instantly

and transform.Rotate is additive

if you want to rotate by 0.01, you just do Rotate(0, 0.01f, 0)

you wouldn't put your current rotation, in any form, as a parameter

but this is a bad idea

you don't do a hardcoded amount

you'd do one frame's worth

which will naturally depend on Time.deltaTime

[unkempt zenith]

Then again, I can only recommend a tweening library like LeanTwean to avoid hassles like these

[leaden ice]

But yeah, just use DoTween or LeanTween

[rigid island]

still good to learn how to do it yourself first, with coroutines + lerp/slerp quaternion etc.

[stone ginkgo]

 {
     flipping = true;

     if (isFacingRight)
     {
         for (var i = 0; i < 1800; i++)
         {
             transform.Rotate(0.0f, 0.1f, 0.0f, Space.World);
         }
     }
     else
     {
         for (var i = 0; i < 1800; i++)
         {
             transform.Rotate(0.0f, 0.1f, 0.0f, Space.World);
         }

     }

     flipping = false;
     isFacingRight = !isFacingRight;      
 }
``` so i put this updated into a coroutine and it correctly rotates the player but not over time, it instantly changes it still

[rigid island]

yeah thats not how that works..lol

[unkempt zenith]

Eh, is it though? All that work, figuring out the exact values, and very obscure code, and for what? When you can just do a single line like MyTweenLibrary.RotateY(obj).Time(time).Ease(ease)

Sure you can say you've done it yourself once, but is it really worth all that time and effort?

[leaden ice]

Quaternion targetRotation;

void Start() {
  targetRotation = Quaternion.identity;
}

void FlipCharacter() {
  isFacingRight = !isFacingRight;
  targetRotation = isFacingRight ? Quaternion.identity : Quaternion.Euler(0, 180, 0);
}

void Update() {
  transform.localRotation = Quaternion.RotateTowards(transform.localRotation, targetRotation, Time.deltaTime * 50);

  // demo, press F to flip
  if (Input.GetKeyDown(KeyCode.F)) FlipCharacter();
}```
Quick example

[leaden ice]

this isn't a valid coroutine

[rigid island]

yes its worth understanding what the code is doing before using libraries that simplify this into one line like you say.
just an opinion

you're not like using asset to "reinvent the wheel" you are gaining knowledge of how Quaternions / Rotation work in unity

[unkempt zenith]

Oh sure that's a different story. I just meant the flip tween of op there

[chilly obsidian]

Im trying to implement a pixelised effect through rendering a render texture through a raw image but I cant seem to get it to work any ideas? It outputs on the camera preview but not on the game screen

[rigid island]

yeah those libraries are pretty nice though, i use DOTween often

[heady iris]

this coroutine never yield returns, so it never actually pauses itself

it completes instantly.

[unkempt zenith]

I'll probably switch to Dotween. I'm currently using leantween and there is no support for text mesh text opacity or colour, which would need to be implemented separately. So I'm interested in trying out alternatives

[hard viper]

the way a coroutine works is you define an IEnumerator like this;

DoX();

yield return new WaitForSeconds(4f);

DoY();

yield return null; // Wait for next frame

DoZ();

if (boolean == true) yield break; // Stop everything

yield return new WaitUntil(()=>boolean); // This waits for something else to make boolean true before we proceed

DoSomethingElse();
}```

understand?

[stone ginkgo]

yes that makes a lot more sense

im gonna install dotween like aa suiggested

[unkempt zenith]

Lol i didn't even know about wait until

Neat

[hard viper]

you should learn basic coroutines before using dotween

dotween is a helpful tool. coroutines are a core mechanic of unity

ie you don’t absolutely need dotween, but you do need coroutines

[rigid island]

yeah i had nothing but problems with leantween for some reason

[unkempt zenith]

Eh. Basic coroutines sure. But there are way better places to apply coroutines. This is clearly a task for a tweening library

It's like saying you should code a sprite animation yourself to learn about XYZ in code, instead of using the animator

But at least imo

[unkempt zenith]

Yeah interested to see others

[hard viper]

he needs to know how to do the timing, since you don’t know if he plans to add non-aesthetic parts to this based on timing.

at any rate, he must learn the fundamentals before he takes the shortcut

[unkempt zenith]

That for sure

[visual flare]

what causes that, each time i launch the editor:

[unkempt zenith]

Sounds like a networking issue. No internet connection, proxies, that sort of thing maybe

But I've never done anything socket related in unity

[mighty juniper]

Does anyone have any tutorials/documentation as to how best to implement a particle system manager? Struggling to find one

[ocean hollow]

a "manager" for particle systems is vague; why is it managing particles? whats the intended effect?

[mighty juniper]

I feel like it would be good practice to have some sort of system where i could do lets say ParticleManager.Play("nameOfEffect", position), and it could do as you'd expect, and all the particles effects could be loaded into a pool after defining them all in the editor. Something like that.

What do you normally do for particles?

[wraith cobalt]

In all fairness, there are some compelling reasons to do just that. =p

[hard viper]

fyi, you can’t easily refer to specific particles to turn them off

[wraith cobalt]

Yeah. Altering the particles array is an all or nothing deal.

[mighty juniper]

Oh right, sorry I've not really worked with them properly before, how would you do it for something like a projectile then? I initially though of just attaching a particle system to the object but the issue is when the projectile collides with something it needs to dissapear along with the particle system that was attached to it, so it wouldnt show properly. Therefore i figured the only way was to have some kind of manager where i could play specific particle effects at specific locations

[ocean hollow]

https://pastebin.com/tDVn6nUy heres an outline

this is meant for a gun system that plays particle effects when it collides with objects, but you can modify this for your need

[mighty juniper]

Not sure i really understand whats going on here fully; you have a list of particle effects for each kind of surface? I would've thought youd have one for each

[ocean hollow]

one for each what?

[mighty juniper]

Oh nevermind i'm being stupid that's your way of pooling them, sorry it makes sense now, thanks.

[half cosmos]

Hi, what can be used besides "GetComponent(Text).enabled = false;" in order to disable certain ui elements?

I'm looking to disable these elements that are a part of a canvas, using scripting

[half cosmos]

Am I getting myself confused? Is this the only way?

These elements would be disabled within an "Onclick" event temporarily and reactivated within another function

[ocean hollow]

public gameObject textBox;

void Start
{
  textBox.SetActive(false);
}

[half cosmos]

thank you!

[minor hazel]

Hey, we have a player that can hold one item with a recipe and item scriptable object. The player currently displays the item they are holding but we want it to for example, show a lettuce and burger, we don’t know how to make it known that the player is holding a burger with lettuce or a burger without lettuce. We need it so we can make the recipe system work, but we just don’t know how to display the fact that the player is holding a burger combined with lettuce or a burger without lettuce.

[ocean hollow]

check if it has children with tag

[half cosmos]

Wait sorry, my issue here in addition to this is that Textbox exists already as "public Text TextBox"

is there another solution?

[ocean hollow]

what is your exact aim?

[half cosmos]

The reason why I've made it "public Text TextBox" is because I change the dialogue within the textbox whenever necessary

[lean sail]

Well first, what is a burger? Does it have a field on it with information if it has lettuce? What is "having lettuce" in code

[half cosmos]

Basically, I'm creating an rpg and I want the dialogue and "attack" and "retreat" button to disappear in order for me to be able to present the player with a list of moves

Hello! is a part of the TextBox element

Attack and retreat, for the attack and retreat buttons

[minor hazel]

basically it’s a recipe system where like say
Burger = Lettuce + Patty + Bun
how would we be able to check if a player has both lettuce and bun at the same time

A burger is a recipe scriptsble object with a list of items that are the ingredients of it

[ocean hollow]

make 2 text box gameobjs, one for attack and one for retreat. if there is a menu open, disable the textboxes. else set them to active. this is much easier than changing the text inside

[minor hazel]

Having lettuce is if like you have lettuce with a burger

[lean sail]

So it has the recipe, but what about items that it currently has? It sounds like you need a way to store this. That is why I ask what is "having lettuce". I know what it means in real life, but what about in your game

It sounds like you just need a list of current items

[minor hazel]

we don’t know how to store what ingredients are on it

that’s our problem

[ocean hollow]

how familiar are you with coding in general? i can think of abt 3 different ways to do this but it wouldnt help you if you cant read or write code properly

[minor hazel]

very, it’s hard to explain what we are trying to do so i’m trying my best

[ocean hollow]

not rlly that hard, just make an array and assign gameobjs to it

[minor hazel]

That might work, like in the player a current item and a list of ingredients on it?

i don’t know why me and my friend were having such trouble thinking of that

brains are fried

[lean sail]

Start by just storing it anywhere

[half cosmos]

Just wanna check, is this what u mean?

[lean sail]

Likely on the same script with the burger recipe

[ocean hollow]

yeah now just enable and disable them when you need to

[half cosmos]

ok tysm lol

[minor hazel]

since it’s a scriptable object tho it’ll apply to all items and not just one

Like we could have a burger with lettuce and burger without at the same time

[hard viper]

is there a solid way to just block all keyboard keybinds while inputting text to an input field?

[heady iris]

Scriptable objects that come from assets should be used to store read-only data.

[minor hazel]

i think we have it figured out

[heady iris]

you can define what a burger is made of with a scriptable object asset

If you want to allow for variations in the recipe, you could add multiple kinds of ingredients

mandatory vs. optional

you'd need a way for the recipe to describe the benefits of using an optional ingredient

[minor hazel]

i think we have an idea on how we are doing it

we already know how the recipe system will work, we just didn’t know how to execute it but i think we got it figured out

i’ll be back if we don’t

[bronze fox]

Does anyone know if the Splines package is available for 2021.3? Information about it is inconsistent accross documentation and forums, and it doesn't appear in my package manager (i.e. some forum users mention using it in that version. Documentation states 2022.1+ and 2021.3+ in different places)

[heady iris]

It looks like older versions were for 2022.1+, but later versions are supported on 2021.3+

[bronze fox]

yes I did notice that (here's the inconsistency that I mean). Any reason why I don't see it in my package manager?

[lean sail]

But something is referencing the scriptable object. That something may also hold the current ingredients

[minor hazel]

yeah that’s our current idea

[bronze fox]

oh, I managed to add it using git com.unity.splines

[hexed oak]

In AudioSource there is a call that allows setting the volume scale in a PlayOneShot overload.
public void PlayOneShot(AudioClip clip, [Internal.DefaultValue("1.0F")] float volumeScale);

Is there a way I can also set the pitch of the audio source just for that one audio clip playing?

[leaden ice]

not with PlayOneShot

[hexed oak]

Right now if I change the audio source pitch it messes up subsequent audio effects

[leaden ice]

why not change it, play the clip, then change it back?

[heady iris]

i forget if that winds up changing the pitch of every one-shot that's currently playing

[leaden ice]

sounds like it might based on what they said?

[heady iris]

i know that i decided to split my UI audio source into two

one for most sounds and one for the varying-pitch clicks my sliders make as they're dragged around

i'm pretty sure i was having that exact issue

(then i completely replaced unity's audio system with FMOD, so it's moot now lol)

[grand bobcat]

Im really annoyed with a collider right now.

Essentialy, i have an object that has a colider, an OnMouseDown function and a script with OnTriggerEnter2D, which should only be effected, to my knowledge, by the collider on that object. But there is also a child object to that object that has a completely seperate collider, but which is also effecting the OnTriggerEnter2D and OnMouseDown, Which is weird because ive had similar systems before that havent had the same issues.

If there is anything i can do to solve this, or anything i may have messed up, please let me know

[leaden ice]

This is expected and how things are supposed to work

[grand bobcat]

is there a way i can negate it?

[leaden ice]

Any colliders that are descendants of a Rigidbody2d are part of that body

[leaden ice]

put the different colliders on separate child objects and put the OnTriggerEnter2D script on that individual child

[mighty juniper]

Anyone know if its possible to get rid of this in VSCode?

IDE0270 Says "null check can be simplified:"

                GameObject projectile = ObjectPool.Instance.GetPooledObject(projectilePrefab);
                if (projectile == null) projectile = ObjectPool.Instance.IncreasePoolObjects(projectilePrefab, 1);```

But if i do:
```cs
 GameObject projectile = ObjectPool.Instance.GetPooledObject(projectilePrefab) ?? ObjectPool.Instance.IncreasePoolObjects(projectilePrefab, 1);```
I get "Unity objects should not use null coalescing."

So either or I get complained at

[leaden ice]

disable the inspection

[ocean hollow]

#pragma warning disable IDE0270 // null check can be simplified

[mighty juniper]

Sometimes they can be quite useful though, just not this one in particular

[leaden ice]

yes disable the specific one

[mighty juniper]

Thanks, i presume i just put this at the top of the script i want it to stop bugging me about?

[ocean hollow]

above your code

GameObject projectile = ObjectPool.Instance.GetPooledObject(projectilePrefab);

above this line ^

[mighty juniper]

Gotcha 👍

[leaden ice]

Pretty sure you can make a .editorconfig file somewhere

[ocean hollow]

then you can restore it afterwards with #pragma warning restore IDE0270 // null check can be simplified

[leaden ice]

and disable it everywhere

[mighty juniper]

Out of curiosity, why does unity not like null coalescing?

[leaden ice]

Unity overrides the == operator

to check for Destroyed objects as well as null references

so this would actually change the behavior

[mighty juniper]

Ah right that makes sense

[sterile sorrel]

How would I find child game objects with a tag? Similar to this
' GameObject[] obstacle = GameObject.FindGameObjectsWithTag("obstacle"); '

[cold parrot]

https://forum.unity.com/threads/finding-all-children-of-object.453466/

[leaden ice]

Either:

• find all objects that are children and then check each object's tag with https://docs.unity3d.com/ScriptReference/Component.CompareTag.html
• find all objects that have that tag and check which ones are children of the object with https://docs.unity3d.com/ScriptReference/Transform.IsChildOf.html

[sterile sorrel]

you see
here
GameObject[] trainStat3EMPTY = GameObject.FindGameObjectsWithTag("trainStat3");

foreach (GameObject position in trainStat3EMPTY)
{
int randomIndex = Random.Range(0, trainStat3.Length);
GameObject randomPrefab = trainStat3[randomIndex];
Instantiate(randomPrefab, position.transform);
}

I want to find each child object with a tag and instantiate into them

[vocal sorrel]

uhhh, small question

i tried using the event system to have my mouse interact with the game world

but for some reason it only works when i click outside the game window first

and then click on the object that is meant to interact with the pointer

[leaden ice]

Do you have your cursor locked?

[vocal sorrel]

after that those methods stop working for some reason, unless i repeat that process

[vocal sorrel]

nope

[leaden ice]

you'll have to show what you tried then

[ocean hollow]

can you send a clip?

[vocal sorrel]

let me try

give a sec

[chilly obsidian]

Does anyone know of any easy ways of adding a pixelation effect to a HDRP project?

[leaden ice]

kind of vague, and not a code question. #archived-hdrp

[ocean hollow]

https://youtu.be/Sru8XDwxC3I

[chilly obsidian]

Thank you for the redirection

[chilly obsidian]

Cant seem to get it to work on HDRP only on URP

[ocean hollow]

whats stopping you from doing so?

[vocal sorrel]

do i just.. send a video file here?

oh

[leaden ice]

as mp4

[vocal sorrel]

yes

i realized haha

this is the clip :)

what should be happening is that whenever i click on one of those squares they duplicate their size

which happens only when i click outside the game window first

[ocean hollow]

looks like you are getting tabbed out after each click but idk what could cause that. does it also do this in a build?

[solemn raven]

hi ,
i wanna test sending a Jsong file from unity to any test server, just to test it
are there any free test servers out there I can try ?

[vocal sorrel]

haven't tried making a build yet, but based on how a youtube video used this thing, it shoud work just fine like that

i'm gonna try making a build ayways

[ocean hollow]

when you alt + tab after clicking a square, does it take you to unity (if you have more than just the editor open)?

[vocal sorrel]

haven't tried that yet

i am gonna try doing that after unity decides to build a single scene

well, making a build didn't work at all

it has the same problem as in the clip

[ocean hollow]

its a coding issue then

[vocal sorrel]

nope, takes me to the second tab

[ocean hollow]

you should review your scripts

[chilly obsidian]

I honestly dont know, the preview camera is showcasing the raw image but the game window is still black

[vocal sorrel]

where do i do that

[ocean hollow]

like i mean just look at your code

[vocal sorrel]

the code isn't complex at all, the only thing that is actually being used is the event system

which confuses me, because it should work correctly

[ocean hollow]

Ig just mess around with the values in the event system 🤷‍♂️

[vocal sorrel]

could you guide me a bit on how to mess with the event system?

i haven't really used it before so this just becomes straight up frustating

unity forums don't seem to address the problem at all

[sterile sorrel]

may I have help with this please

[graceful patio]

whats the best apporach to
Rendering fire? on 2d

i tried using a partical system it looks mid tbh

[dusk apex]

You were given a lot of suggestions

[graceful patio]

perfereably a way that doesnt require too much math
but if its necesary

[sterile sorrel]

Im unsure how to make it find with a tag and instantiate on the found ones

[ocean hollow]

animation

[leaden ice]

I explained your two possible approaches here; #archived-code-general message

[dusk apex]

This is the general coding channel. If it's not specifically code related, try #💻┃unity-talk

[sterile sorrel]

Those are for colliding

[leaden ice]

They are not for colliding

[sterile sorrel]

Ok

[ocean hollow]

what is your vlaue for input actions/s and repeat delay?

[leaden ice]

read what I wrote

[vocal sorrel]

does it have to be realtime rendering?

[vocal sorrel]

i think i know what muight be wrong

[graceful patio]

i would like it to (so i can take advantage of noise and what not)

[dusk apex]

The discussion moved to #💻┃unity-talk message as it isn't code related

[graceful patio]

i think

[vocal sorrel]

i am using the new input system, that component you use is for the old input manager

[vocal sorrel]

oh, ok

[vocal sorrel]

@ocean hollow are you aware of any incompatibilities between the input system and the event system?

[ocean hollow]

incompatabilities in what sense?

thats a bit vague

[heady iris]

show your code.

[vocal sorrel]

like, those two systems not working properly with one another

[vocal sorrel]

ok

[ocean hollow]

theres no reason for that to happen, they are both independent of each other

[vocal sorrel]

do i send a screenshot?

(this is the only code using the event system in any case)

[ocean hollow]

for larger scripts like this, you should use services like pastebin but this is ok for now

[vocal sorrel]

ok, sorry for the big code

[heady iris]

use Debug.Log to check if the method is actually running every time you click the mouse

just to verify that you are, indeed, not receiving more than one event when you click repeatedly

[vocal sorrel]

it isn't running everytime i click

it should run whenever i click over any of those squared

but it only works after "refocusing the window"

which is weird

because other than that the code actually works consistently

[heady iris]

so you added a Debug.Log statement that before the if (data.button == 0) line?

and it only printed once?

[vocal sorrel]

yup

it only printed again after i did what is shown on the clip

the whole clicking outside the game window

[heady iris]

Do the other methods run? try adding log messages to those as well

[vocal sorrel]

those are inconsistent as well

they work under the same circumstances

[ocean hollow]

you never answered me #archived-code-general message :(

[vocal sorrel]

default values

sorry for not answering

i thought i did tho

[ocean hollow]

I've never seen something like this so I would reccomend creating a new project and replicating your setup rn to see if it still does the same thing

[vocal sorrel]

ok, thanks :)

[deep oyster]

I've got a player character, and I've got items that might be in the world that the player might be able to pick up. How do I highlight "The closest item to the player out of the list of items that the player is in range of"

I guess I could just go through a list of all items every frame and check the distance of each one

probably not that big a deal but it feels weird

[leaden ice]

OnTriggerEnter/OnTriggerExit

keep a list of them

go through that list each frame

[deep oyster]

Yeah, ok

[gusty aurora]

I would like to GetComponent<Generator<T>>() for any T that derives from a given base class.

[hard viper]

then use an interface

unity hates when you have generic monobehaviours anyway

almost every time I have a generic monobehaviour, I need to define a specific non-generic class that inherits from the generic class to make it concrete

[leaden ice]

Make your own generic function:

T GetGenerator<T>() {
  GetComponent<Generator<T>>();
}```

[gusty aurora]

I also feel like I'm running into problem after problem with Generics

[hard viper]

like
FixedSpawnpointSingle : FixedSpawnpointBase<TilePlacement>

[gusty aurora]

The don't work with editor scripts, every time it's painful

[hard viper]

what

i’m telling you to make all your generic monobehaviours be a base class for a nongeneric one foreach specific set of generic arguments

wtf does this have to do with editor scripts

[silver crown]

Class Dog : Monobehaviour
Class BigDog : Dog
Class BiggerDog : BigDog

[hard viper]

class Dog<T> : MonoBehaviour
class BigDog : Dog<int>
class BlackDog : Dog<Color>

[silver crown]

You maybe are not implementing them correctly/necessarily

[silver crown]

Hmm, this is new. Can you elaborate a little

The <type> after inheritance

[cosmic rain]

That's generic types. It's what they were asking/talking about.

[silver crown]

Oh, my message was in regards to this message.
#archived-code-general message

I thought generics were the base classes being derived from

[hard viper]

no. generic classes are classes with type arguments

like how you can have List<int>

[silver crown]

Ok, do you have an example of a use case? Or will docs have a valid demonstration?

[latent latch]

What if you want a big black dog tho

[gusty aurora]

PlanetGenerator<T> : MonoBehaviour where T : Planet

I want to do, in another script, GetComponent<xxxxx> where xxx would be anything like PlanetGenerator<Planet1>, PlanetGenerator<Planet2>, etc

I'm not sure if that's clearer

I feel like I can't use a non-generic base class here

[latent latch]

made need to type check after* component checking

[leaden ice]

Can't you just do that now?

GetComponent<PlanetGenerator<Planet1>>()

[latent latch]

Oh, yeah you should be. It would be concrete I'd believe

[leaden ice]

If you want ANY of the generators then you need a non generic base class or an interface

[latent latch]

you do need the constraint though, otherwise you'd type check

[gusty aurora]

so now I have PlanetGenerator<T> : PlanetGeneratorNonGeneric where T : Planet

but my PlanetGenerator<T> has a field public T planet

I can't have that field in the non-generic one

Generics are such a nightmare to me

[latent latch]

if you dont want to use generics, just use fields and more abstraction

[gusty aurora]

I kinda like them tbh

I don't like the fact you can't add them to components

and can't create custom editors

what do you call type check ?

[latent latch]

you can, but it needs to be concrete

[gusty aurora]

Run thought the list of all possible Planet1, Planet2 etc ?

[latent latch]

T: Planet isn't good enough as it could be any type which derives from Planet

[latent latch]

That can be serialized on the editor because it's not ambiguous to it

otherwise you're looking into serializedreferences

[gusty aurora]

So I would be replacing this

if (this.TryGetComponent<PlanetGenerator<T>>(out var planetGenerator)) { Generate(planetGenerator.planet); }

by that

if (this.TryGetComponent<PlanetGeneratorNonGeneric>(out var planetGenerator2)) { if (planetGenerator2.planet is T planet) { Generate(planet); } }

[hard viper]

Remember you can also make IGenerator

then GetComponent<IGenerator>

because it sounds like you just need to invoke a single public generator method

[gusty aurora]

I need to get the T planet in PlanetGenerator<T>

that's pretty much all I need

That's where I don't see how to use interfaces here

an IGenerator class couldn't have a T planet field =x

[latent latch]

if(planetGenerator2.planet is Planet planet)

if(planetGenerator2.planet is DerivedPlanet1 planet)
if(planetGenerator2.planet is DerivedPlanet2 planet)

[heady iris]

Why does the planet generator need a type parameter?

[sterile sorrel]

how would I do something like
if (transformName.transform.IsChildOf(gameObject))
but the transformName as a game object

[heady iris]

This reminds me of a problem I had. I made a class generic so that I could avoid repeating a few lines of code in each one (each class got a "Config" type with some per-class properties on it)

[gusty aurora]

Because it does

GameObject planetGO = CreateEmptyGameObject(planetName); T planet = planetGO.AddComponent<T>();

[heady iris]

If that's all you're using the type parameter for, I'd seriously consider just passing it a Type

[gusty aurora]

Also stores a reference to a T planet

[heady iris]

AddComponent has a non-generic version that takes a Type

The other option is to derive the generic type from a non-generic type

This works if the generic type is "invisible" from the outside

i.e. there are no public fields of type T

[heady iris]

It's kind of ugly, but it's what I was doing here (and I'm still doing it in another place)

[gusty aurora]

Makes sense

It has a public field though

[SerializeField, ReadOnly] private T _planet; public T planet { get { if (_planet == null) { _planet = GeneratePlanet(); } return _planet; } }

[heady iris]

If you must be able to get a specific type of planet out of it, then this is a non-starter -- a non-generic planet generator class wouldn't be able to actually give you a specific kind of planet

[gusty aurora]

I didn't know about passing a type to AddComponent though

[heady iris]

If you're fine with just getting a Planet out, then you can just return a Planet

[still gust]

Can anyone point me in a direction on how to start path generation. Just the steps it should take or anything else. (I'm trying to make a path on a tile based map I generated)

[heady iris]

make an abstract property on your "wrapper" PlanetGenerator class that returns a Planet, then implement it in PlanetGeneratorImplementation<T> (i don't like the name but i've had trouble coming up with a better one)

public abstract class PlanetGenerator {
  public abstract Planet { get; }
}

public class PlanetGeneratorImpl<T> : PlanetGenerator where T : Planet {
  protected T planet;
  public override Planet => planet;
}

[gusty aurora]

Then I would have to cast planetGenerator.Planet as T everytime I use it

Sounds like it could work, let me try

[heady iris]

Right, but that's inevitable.

[gusty aurora]

I called the first one PlanetGeneratorNonGeneric

[heady iris]

If you want to get a specific type out, you must know about the generic type.

But if you must know about the generic type, you're unable to reason about any kind of planet generator

you have to reason about a specific kind of planet generator

These are two incompatible ideas.

[heady iris]

You'd have to abuse the is operator here

if (generator.Planet is PlanetA planetA) {
  // ...
}

this generally suggests that you should be using polymorphism

Get rid of the generic type and just call virtual methods on Planet

I don't see how PlanetGenerator<T> makes any sense unless it's abstract

The generic planet generator would only be able to do things to its planet that any Planet allows

since all it would know is that T : Planet

[gusty aurora]

It is abstract

[heady iris]

So you have a bunch of derived classes?

Why do they need to be able to return a specific kind of planet instead of just giving you a Planet?

[gusty aurora]

Then I have PlanetGenerator_A : PlanetGenerator<PlanetA>

And for that class PlanetGenerator_A, the field public T planet from PlanetGenerator is now a public PlanetA planet

[heady iris]

that was my exact motivation here

actually, let me see if I can find the very long-winded discussion I had on this exact subject

#archived-code-general message

[gusty aurora]

I guess they could all return a simple Planet, and then I would use is everytime I access it

[heady iris]

Why do you need to know what kind of planet the planet generator produced?

If you want to do something that's defined for every kind of planet, it should be a virtual method of Planet

if you want to do something that only works for one kind of planet, you should already know what kind of planet it is (meaning that you never have to get it from the planet generator in the first place)

[gusty aurora]

I have a bunch of other components, that add features to the newly created planet

if (this.TryGetComponent<PlanetGenerator<T>>(out var planetGenerator)) { AddFeature(planetGenerator.planet); }

In the class abstract class FeatureGenerator<T> MonoBehaviour where T : Planet

[heady iris]

oh, well, you already know T here

that looks fine

[gusty aurora]

As in, the planet generator is creating a barebones planet of type T, and the generators add features to it

[heady iris]

PlanetGenerator<T> is a specific type here

[gusty aurora]

The issue is that, in an derived class GravityFieldGenerator : FeatureGenerator<Planet>

T is planet

but in the associated PlanetGenerator, T could be PlanetA or PlanetB

[heady iris]

Ah, okay, this makes more sense to me

I was thinking you were operating without any constraints at all, and that you wanted to do something specific to each kind of planet

[gusty aurora]

Hence why I wanted to GetComponent<xxx> where xx is any class that looks like PlanetGenerator<T> where T : Planet

[heady iris]

which would be the horrible abuse of is

[gusty aurora]

T is planet but in the associated PlanetGenerator, T could be PlanetA or PlanetB
So, when I call TryGetComponent<PlanetGenerator<T>>, I don't get any result

[heady iris]

This would be covariance -- reinterpreting PlanetGenerator<SpecificPlanet> as PlanetGenerator<Planet>. C# can't do that.

[heady iris]

In this situation, I think using is is pretty reasonable.

[gusty aurora]

tbf I learned about covariance a few hours ago when researching, and I realized this whole topic is way more complex than I imagined

[heady iris]

i always have to look it up to make sure i'm thinking about it the right way round

[latent latch]

if you think you need covariance you probably dont need covariance

[heady iris]

I was wondering if there is way to simplify getSrc? looking for feedback

[leaden ice]

Split up the http stuff and the parsing stuff.

IEnumerator GetSource(string url)
{
    UnityWebRequest www = UnityWebRequest.Get(url);
    yield return www.SendWebRequest();
    if(www.result != UnityWebRequest.Result.Success)
    {
        Debug.LogError(www.error);
        yield break;
    }

    string responseData = www.downloadHandler.text;
    ProcessResponse(responseData);
}```

[dark kindle]

thank, that seem be cleaner

[dark kindle]

some time later i realize for my purpos that i didnt need (dont think i need, perhaps) for loop to all words, i parse regex in form of xx/xx/xx directly on responseData

[lean sail]

If I instantiate a scriptable object at runtime, am I supposed to destroy it myself later? Im unsure if its causing a memory leak

[plucky inlet]

What do you mean by instantiate the SO? Like create a new SO asset file or an instance at runtime?

[lean sail]

instantiate at runtime, i think I have a memory issue because after testing with a few thousand objects (which all instantiate an SO), unity said im running out of memory

[plucky inlet]

Is your photon network stuff actually transferred over to the new scene or do you just replace the scene and lose all of the photon functionality?

[lean sail]

to clarify, i was exiting and reentering playmode between this, on like the 4th time it said this

[plucky inlet]

How do you instantiate it?

[lean sail]

By using the instantiate function..

[plucky inlet]

I would hook into some photon event callbacks to see, if like the match is getting destroyed or something else. Did oyu try that?

[plucky inlet]

I just feel like you are misusing scriptable objects right here. They are not meant to be instantiated at runtime, if you really reference to the YourSOClass : ScriptableObject file

[lean sail]

i need unique instances, these are used for items to keep track of effects like "do X after Y seconds". Otherwise all characters with this item will share the effect.
I know i could just use a poco, but 🤷‍♂️ if i can get away with just instantiating the SO then I might as well. And my original question was about if i need to clean up the instance myself with destroy

[dull quarry]

    {
        yield return new WaitForSeconds(2);
        box.enabled = false;
        yield return new WaitForSeconds(5);
        GetComponent<PhotonView>().RPC("powrot", PhotonTargets.All, ofiara , zabujca);
        GetComponent<PhotonView>().RPC("ustawienia_pocz2", ofiara);
        
    }```  ```[PunRPC]
    void ustawienia_pocz2(PhotonPlayer ofiara)
    {
        if(ofiara.isLocal)
        {
            mozesz_strzelac = false;
        }
        
    }```

[lean sail]

there is a photon related chat pinned in #archived-networking

[plucky inlet]

So from what I know, you should not be meant to destroy them after instantiating when leaving playmode, cause all instances should get destroyed and all SOs will get be reverted to their default settings (at least on runtime). Did you check the profiler and memory consumption?

[plucky inlet]

https://forum.unity.com/threads/scriptableobject-createinstance-vs-instantiate.515757/#post-3382718

[lean sail]

well i see my memory going near 6gb on my task manager 😅 but suddenly not doing that when i destroy them in a dtor of my item class

ive read a bit of that thread, they dont seem to mention destroying it

[plucky inlet]

Even if its 2018 he posted that, it might still be the same issue. You cluttering up things while doing something SOs are not meant to be used for 😉

Just for testing, did you try to mimic the SOs values with an actual class/monobehaviour and use that instead of directly instantiating the SO?

[lean sail]

i dont really see how thats related, im fully aware i could just use a POCO. I just didnt want to create what is essentially a wrapper class for my SO to do that at the moment. My question at the end of the day really is just about if i am supposed to call Destroy on it. I dont really care if it affects editor performance, people arent running my game in the editor.

[plucky inlet]

Well, than I guess, I dont have the answer for you, cause I never ran into that problem. To find out, I would just try it at runtime and see if it has the same performance hit as in editor

[lean sail]

🤔 i am doing all of this at runtime

[plucky inlet]

Oh, so you profiled your runtime, sorry, wasnt clear about that

[lean sail]

Well if anyone knows the direct answer, let me know. Clarified the question a little more

[plucky inlet]

Well, than I think you already answered it yourself. You gotta destroy it if you wanna use SOs out of usage scope. At least if your profiling returns that outcome of free memory after doing so

[pure onyx]

Hello i don't know where to ask

I have a problem same like this forum https://forum.unity.com/threads/alternative-to-mobile-particles-additive-shader.1286603/
But I still haven't found the solution. Does anyone know the solution? I want to masking while using Mobile/Particles/Additive shader. Thank you

[plucky inlet]

If I am reading correctly, the answer in the thread already answers a solution you could try? Or what is your exact problem, the stencil warning?

[lean sail]

damn I didnt realize i could use that resources function here. From a bit more testing, it seems like my poco destructor is just never getting called and i was never destroying the SO at runtime in any test

[knotty sun]

that explains it, in my own testing SO's were being cleaned up correctly as I expected

[pure onyx]

Sorry, I still don't understand the answer on the forum. Where can I download the mobile particles additive source code and add stencils?

[latent latch]

you can probably just open it on the editor

[pure onyx]

oh and then add stencil properties by script ?

[plucky inlet]

Hence the difference in the forum using CreateInstance vs bawsi using Instantiate. Just to point it out

[latent latch]

probably, otherwise just make your own masking shader

[pure onyx]

ok thank you

[latent latch]

there's also urp render objects that can stencil by layers, but havent really played around with it for the UI

[knotty sun]

I missed that point, yeah, I've never used Instantiate with an SO

[pure onyx]

ok thank you, i will try it

[knotty sun]

@lean sail If you use Instantiate on an SO is it doing a deep or shallow copy?

[latent latch]

instantiate should work like instantiating a prefab

while createinstance gives you the defaults of a new instance

[knotty sun]

so shallow copy, I use my own deep copy technology for instantiating SO's

[lean sail]

i dont get what you mean, which comment in there says a specific difference vs the 2? One comment mentions the performance difference, but none really say that one creates garbage while the other doesnt

[plucky inlet]

CreateInstance is basically what you can do with the context menu in the editor, you create a new "file"

[midnight blaze]

how can i fix my code it says theres some error at line 5,51 but i cant find the issue

[latent latch]

print to console or add breakpoints near the line of execution

[midnight blaze]

ill try

[plucky inlet]

Also "some error" might not exactly what the console is outputting. You could copy paste the error here

[midnight blaze]

mk

CS1003 is the error code

[knotty sun]

what is the exact error message?

[thin aurora]

That means a character is expected where the error is

[knotty sun]

and the line of code is?

[thin aurora]

Next time actually share the error. Consider sharing the !code in here if you can't find it and specify where the error mentions the error.

mhm

can actually play test it now

[lean sail]

would this solve the issue? I have instances of a poco which all right now hold an instance of an SO. The poco itself isnt being destroyed, so im not really sure what i can do there.
These are items (poco) which hold Effects (SO). Some of these effects need to keep track of the time or some other counter, so i instantiated them or the value would be shared for every item. I can combine items, if the user picks up one they have already, it adds to a counter on item 1 and item 2 is no longer referenced.

[knotty sun]

if the POCO is not being disposed then the only way to release the SO to the GC is to null out the reference

you could also implement the IDisposable interface on your SO class

[lean sail]

alright thanks ill try implementing that. Worst case ill just destroy the SO in some item.Combine function but it is slightly concerning that these never got destroyed by themselves

[knotty sun]

nothing will get disposed of by the GC as long as it has a reference held somewhere or is manually disposed of

it sounds like the problem lies with your POCO rather than with the SO

[lean sail]

thats what I was thinking and was testing around for right now. Im not really sure how it works because i wrote a test script which creates an item and then no longer references it. it still never gets destroyed but ill have to experiment more later. must go for now

[knotty sun]

one thing for you to look at, put IDisposable on the POCO

Hey folks, just out of curiosity, is there a way to safely remove package data from my cache in unity? Been getting a lot of these with URP lately:

I have two different projects using URP, one of which was a copy of a project I made as a backup, which is where I think this issue is coming from. I was thinking I'd try and delete the "PackageCache/.com.unity.render-pipelines.core@14.0.10" folder and reinstall URP, but I wanted to ask some people more knowledgeable than me first before I do anything too hasty. Don't wanna mess up my whole project or make things even worse.

[cold parrot]

If you delete a cache it will simply be recreated on demand

[fiery sinew]

How do survival games handle serializing and saving objects? Like when player cuts trees or builds a house.

there are a lot of tutorials for playerstats to json but can't find for others

[onyx glade]

Thanks, I figured as much. I'll see what I can do then

[onyx glade]

Update: Removed & Reinstalled URP on both projects, and this seemed to have fixed it. Thanks for the help!

[rocky jackal]

How can i get the normal vector of a collider at the collision point of two objects ?

[latent latch]

doesn't collisional data give you that already

if you're using trigger colliders though you'd probably either raycast or compare using ClosestPoint method

[rocky jackal]

Okay, didnt know that. Thank you

[leaden ice]

https://docs.unity3d.com/ScriptReference/ContactPoint-normal.html

[latent latch]

Probably want to iterate through them and get an average out of em

[hard viper]

one thing to note is that a collision can have multiple contact points with different normals

[rocky jackal]

okay thank oyu, ill try getting the average normal vector then

[hard viper]

red shape makes contact with blue shape. You can call .GetContacts on the Collision2D, which will get you all the different contact points. And each contact point has a separate normal

Which gives the contacts generated at the end of the last physics sim, even if you moved shit since then

If you need to figure out something like, if mario is touching a goomba from the side or from above, I can recommend using Collider2D.Distance, which gives you the shortest displacement vector to bring the two things into contact

[hard viper]

I strongly recommend against getting any sort of averaged normal vector

if mario is touching a wall and ground at the same time, you might think the avg normal is at a 45 degree angle. But you can have multiple contacts to one face. So you might have 2 ground + 1 wall contact, 2 +2, 1+2, or 1+1. This gets very complex very fast, and none of the averages is an actual normal

[latent latch]

there's more specific averaging operations out there for this I remember coming upon

for those cases where you do have a lot of focused points in a specific area

[hard viper]

imo, you should only break down into contact normals when you are actually planning on reading each separately

like if you want mario to get contacts to check if he is touching ground and/or wall, and putting them into separate bools

otherwise you probably want .Distance

make sense?

[rocky jackal]

its a bit more complicated then that, Im making a vr game with gorilla tag like movment(you can push yourself arround by hitting the ground basically) and this works by taking the difference between where the hand should be and where it actually is and it then moves the player so the two things match up and it also adds the negative player rb velocity to cancel out sliding. heres the thing i need to multiply this with a low number on steep surfaces so you can slide down them and your hands dont have much grip. But i also want you to be able to still push yourself away drom the surface your sliding on and you should be able to use 100% of your force along the direction of the normal vector so you can for example slide down a building but throw yourself in the air while sliding down the surface to cathc a rope for example

[hard viper]

this isn’t the most uncommon scenario

you need to know the effective surface normal

getting this by contact points will 100% give you multiple contact points with different normals, and taking the average normal will mess you up

other ways to get normals involve other physics queries, like casting

[latent latch]

problem with casting is you still need to know the location you want

[hard viper]

if you cast a shape in a given vector from a given position, you will get a unique RaycastHit3D, and it will give a unique normal

[hard viper]

that kind of depends on exactly how he wants to time it

Cast to get normal for something with which you are not in contact.

[rocky jackal]

the location i want for what ?

the location of the contact ?

[hard viper]

you need to know the start pos and desired end pos, so you can cast from start with a displacement vector

[latent latch]

right, because you may have made contact at different points

[hard viper]

and you WILL make contact at different points

it WILL happen, and you must be ready for it

Collider2D.Distance has an equiv 3D method that I think is called CalculatePenetration or something

if two things are in contact, it will give the smallest vector that you need to separate them
