[merry stream]

so to do spacial audio, should everything that plays a sound have an audio source or is there a way to play a sound specifying a location

or would that require insantiating an empty game object which is a waste of resources

[spring creek]

PlayClipAtPoint (might be off on the name) is a thing
And yeah it creates an empty object

It's fine somewhat sparingly

[merry stream]

well I would use it for every sound in my game, so better to go the audio source on everything route?

100s of projectiles hitting making sounds etc, id imagine thats too much for no reaosn

[spring creek]

Yeaaah, I would think that audiosource would be better at that point.
Never tested it though.
Does it NEED to be at a specific location, or would a few objects with sources offset from the player work

[merry stream]

ah that could be interesting, its a 2d game so it could

like have a few in each corner and sides to create the effect

but then wouldn't you have to calculate which one to play the sound from based on the location where it "should"?

[latent latch]

id check if an audio was played recently and just play one clip

[merry stream]

wdym?

[latent latch]

if you got multiple things hitting a wall in one frame then playing the audio clip 100x times seems excessive

[glossy gust]

i would normally serialize the field

but i can't drag that in the inspector

since it is not present before startinfg

[merry stream]

well right now I do that, just cull audio clips trying to play after a certain number are already playing

but im using an audio singleton and am trying to move away from that

and include spcial audio since right now everything just plays at the player

[latent latch]

ah, ok. I've not really touched audio. It's only one of those things I consider the polish of the game

[merry stream]

that is true

trying to get the game in a somewhat decent state though

[merry stream]

what do you think of object pooling empty game objects with audio sources and moving them around to play the audio at a certain point?

avoiding instantiation over and over

[latent latch]

I've been told that audio itself requires a bit more handling with pooling as the clip themselves can be rather large when loaded

[merry stream]

handling as in?

[latent latch]

not have all the audio loaded at once

[merry stream]

well I have all my audio stored in an SO

so it would fetch from that

[latent latch]

right, but eventually you do want to use asset bundles as having all your assets loaded at once is something you eventually have to fix

[merry stream]

ah i see, i dont know if my game will grow to be that large

[latent latch]

audio, textures, and models are usually the main culprit, but mostly textures

[merry stream]

yea, my game is 2d pixel art so I don't think that will be the issue

[spring creek]

https://unity.huh.how/references
Gonna have to use other methods then. Singletons are usually a good way to handle that specific case

[merry stream]

ill consider it though

perhaps my SO can load the audio in from resources only when it is requested by a source?

and it will cache it in a dictionary once its loaded for the first time

[latent latch]

I loaded vfx by asset bundles through checking the ability I am using then loading it in then adding it to the pool

stuff like that

[merry stream]

so are asset bundles more of a editor optimization or actual delivery optimization

[latent latch]

it's more specific to runtime performance

another optimization

(more noticable on mobile and webgl)

[merry stream]

but if everything just loads when the game starts up, there won't be any lag during gameplay? or am i missing something

[latent latch]

that's true, but you don't want to have more stuff loaded into mem than you need if you're not using it

[merry stream]

is everything from resources loaded in on start in a build version?

[latent latch]

even if mem is pretty abundant, and that cacheing is preferred, there's no reason to have all your 8k tree textures loaded when you're in the cave section of your game.

[merry stream]

ah i see

okay

though its more relevant for 3d games with good graphics id assume

[glossy gust]

okay so ill just use tags then

thanks

[latent latch]

it's larger issue for mobile, but nowdays devices have a lot more mem.

still, no reason to have all of your large textures or full soundtrack scores loaded in all at once

[spring creek]

Tags are ok, singleton may (or may not) be better. What thing are you trying to reference?

[high condor]

is there a way to change just the alpha color of a sprite renderer?

[leaden ice]

same way you change any other part of the color

Color c = myRenderer.color;
c.a = whatever;
myRenderer.color = c;```

[high condor]

thanks; before, i had tried to convert it through doing something like sr.color.a = new Color(blah blah blah)

[spring creek]

You can do that by sr.color = new Color(blah, blah, blah, blah)

That is fine

[high condor]

or yea thats what i meant

but no that wasnt working for me

[spring creek]

Because it changes everything?

[high condor]

it said that spriterenderer.color doesnt work cuz it's not a variable to be changed, just a return statement

[spring creek]

Are you sure that wasn't color.a ?

Because you can certainly assign to color (as praetor just wrote)

[leaden ice]

So exactly what Aethenosity said.

[high condor]

yea :p

[spring creek]

Also keep in mind, color is 0 to 1

Not to 255

[leaden ice]

sr.color = new Color(sr.color.r, sr.color.g, sr.color.b, newAlpha); is an option but ugly and inefficient

[high condor]

oops

[leaden ice]

but yeah 255 should be 1

[high condor]

i just thought it would work because i thought it would just count sr.color as a Color variable instead of a return

the more you know

[leaden ice]

it's a property

so it's actually a function

it's a bit like this

class Renderer {
  Color c;

  public Color GetColor() {
    return c;
  }
}

// some other code
void Example() {
  Renderer myRend = ...;
  myRend.GetColor().a = 100; // this doesn't work because Color is a struct. You are just modifying a copy
}```

The property hides that away sneakily

[merry stream]

why is that when i use the profiler, my game lags like crazy making it super hard to tell whats actually causing the lag

[ocean hollow]

not a coding question

[leaden ice]

because the profiler itself takes up computing resources too

[merry stream]

yeah, but stull like getting input is showing as taking up 99% of the frame time

obviously its not

[leaden ice]

well it could be...

[gusty aurora]

Sorry didn't follow the discussion, what's inefficient about that ?

[leaden ice]

it copies sr.color multiple extra times

[spring creek]

Every time you read it, you get a newly allocated copy

[leaden ice]

every one of those sr.colors is a call to the property getter and a copying of the whole Color struct

[dim spindle]

can you share your profiler view

[merry stream]

i fixed it dw

it was spamming log messages causing lag

[floral raft]

Hello Need help!

I have made the Main menu and there's an object who's not in scene but associated with the game screen and it's in start method it asks for for two components in the gameplay screen, i thought the problem fixed already when there's a method finds an object with tag

I have made two scenes one for main menu and the other gameplay when i click play

[ocean echo]

is it possible to code somethign where when you click on the button you switch scenes but theres also a fade animation between them?

[floral raft]

I get this message on console screen in main menu but when I click play button which switches me to the other scene the problem will gone.

The file that has 'PepeTrigger' script and its not in the scene

this is in 'PepeTrigger' script, I don't know why it executes itself in main menu screen when she is not in the main menu

[spring creek]

Can you show the editor in the scene you get the error?

[spring creek]

Yes it is

Easiest is to fade out to black, switch scenes, fade in from black

But otherwise you can do an additive load and the unload with each kinda crossfading

[ocean echo]

i see ty

[floral raft]

When I press play button the console error goes away

[spring creek]

Where is logic in that scene?

[floral raft]

hold on

[spring creek]

Ok, can you show the inspector for the "MainMainueLogic" object

[floral raft]

PipeTrigger script is on an Object that is not in the scene and I made it that way so it clones forever

sure

[merry stream]

does anyone have some intermediate level sources for unity? most of the stuff on youtube includes a lot of bad practices and is more geared towards absolute beginners

[spring creek]

Have you checked out catlikecoding?

[merry stream]

nope, will do

[spring creek]

Or sebastien lague

[merry stream]

love him

[spring creek]

Isn't tagged Logic

So it can't find it

Oh wait

Doesn't have the LogicScript either

[floral raft]

LogicScript on the gameplay scene

and the other scene is off

I think the object that is not on the scene executes itself no matter what

[spring creek]

Yeah, in the main menu scene hierarchy search, type t:PepeTrigger

[spring creek]

No, if there is no instance, it will not execute (except static scripts which technically don't have an instance)

[spring creek]

This is in "MainMenueScreen" scene?

[floral raft]

nope in gameplay screen

hold on will write it on mainmenu

Still the same

[floral raft]

Same result

The game still playable its okay, but it's bit annoying in editor

[spring creek]

Ohhhh wait

It pops up after spawning a pipe of course

So yeah, won't show in the hierarchy view at first

[floral raft]

Oh no, the main menu will look ugly after removing spawning pipes

[spring creek]

You can just have a bool in start that says menuScreen and disable looking for logic.

Kind of a dirty hack

But quick and easy

[floral raft]

You couldn't say it any better

I'm the creator of that thing, but you could find it and that shows how good you're 🙂

Thank you for giving me the reason + the fix

Hope you have a nice day! Thank you so much.

[spring creek]

No problem. Best of luck

[floral raft]

Perfect! thank you again!

[spring creek]

Ah nice choice

its not working

[carmine iris]

Hello guys I have a question. As you can see there is 3 lines in the game. When the player taps to left of the screen, the ship will go to one line left. If the player taps to right of the screen, the ship will go to one line right. For this what methods and strategies that I should follow? How can I do this? I tried to make it with new input system but I am confused.

[plain ibex]

"if (collision.collider.CompareTag("Ballet")" works but its not destroying balletObject

[leaden ice]

Just divide the touch position by the screen width

[spring creek]

You aren't expecting balletObject to be the thing instantiated, right?

What IS balletObject?

[leaden ice]

What is it supposed to be doing?

[plain ibex]

im doing this because: https://unity.huh.how/references/prefabs-referencing-components

[carmine iris]

I made something like this. Would it work? Also how can I simulate mobile touches from computer?

[spring creek]

What does this mean?
This doesn't explain your code much

I asked what balletObject is...

[prime sinew]

https://www.youtube.com/watch?v=uokF9CmUs9c

i'm afraid multi touch isn't testable though, I think, if that's what you mean by mobile touches

[carmine iris]

ohh yes let me check it thanks

[plain ibex]

its an original game object and i instantiate it for bullet system

[spring creek]

Then you are destroying the wrong thing, as I throught at first

You want to destroy instance

[lofty crest]

is there a way for me to change a whole bunch of sprite renderers at once using c#

something like void
FlashWhileInvincible()
{
sr.material.color = pState.invincible ? Color.Lerp(Color.white, Color.black, Mathf.PingPong(Time.time * hitFlashSpeed, 1.0f)) : Color.white;
}
but for a whole list of sprite renderers

[plain ibex]

how

[spring creek]

Sorry, edited.
But you want to destroy instance

The thing you created

Unless I am misunderstanding you

[plain ibex]

public void shotButtonClick()
    {
        GameObject last = Instantiate(balletObject, balletSpawnpoint, Quaternion.identity);
        rb = last.GetComponent<Rigidbody2D>();
        rb.velocity = new Vector2(dirTargetObj.transform.position.x - balletSpawnpoint.x, dirTargetObj.transform.position.y - balletSpawnpoint.y).normalized * atisHizi;
    }```
Actually, i instantiate balletObject in different function.

[plain ibex]

and my problem was that i cant assign balletObject because

[spring creek]

last is the thing instantiated

[plain ibex]

because if prefab is in assets i cant assign gameobjects to it

[spring creek]

Correct

To clarify, ALL prefabs are assets btw

[plain ibex]

so i tried it for assign

and there is no errors but it doesnt destroy balletObject

[spring creek]

instance is the thing that was instantiated. That is the thing you want to destroy

balletObject is the prefab, right?

[plain ibex]

yep

[spring creek]

Then do not try to destroy balletObject

Destroy instance

The object you created and named instance

[plain ibex]

it didnt work

[spring creek]

What did you do

"Didn't work" is always an unhelpful response

[plain ibex]

i changed it like this:
Destroy(instance);

[spring creek]

That couldn't have been the only change without getting a compiler error

Share the whole code as it is now

[plain ibex]

using UnityEngine;

public class Enemies : MonoBehaviour
{
    public int enemyHealth;
    [SerializeField] float enemySpeed;
    private Rigidbody2D rb;
    [SerializeField] private BalletScript balletScript;

    private float randomTowerY;
    BalletScript instance;

        rb = GetComponent<Rigidbody2D>();
        rb.velocity = new Vector2(7.75f - transform.position.x, randomTowerY - transform.position.y).normalized * enemySpeed;
        balletScript = GetComponent<BalletScript>();
    }

    private void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.collider.CompareTag("Tower"))
        {
            Destroy(gameObject);
        }
        if (collision.collider.CompareTag("Ballet"))
        {
            Destroy(instance);
            enemyHealth -= 60;
        }
    }

    private void Update()
    {
            if (enemyHealth <= 0)
            {
                Destroy(gameObject);
            }
    }

    private void OnBecameInvisible()
    {
        Destroy(gameObject);
    }
}

[spring creek]

Gotcha. You are destroying the script only

Do Destroy(instance.gameObject)

[plain ibex]

now it says me assign the instance but i cant assign it from inspector you know

[spring creek]

You can assign the prefab? What do you mean. Please show errors word for word if there is an error. instance is instantiated, so it doesn't need to be assigned in the inspector

[plain ibex]

NullReferenceException: Object reference not set to an instance of an object
Enemies.Update () (at Assets/Scripts/Enemies.cs:43)

[spring creek]

Ok, and line 43?

[plain ibex]

Destroy(instance.gameObject);

[spring creek]

One thing I notice. Where is SpawnAndConfigurePrefab() called?

[plain ibex]

in Enemies.cs
public void SpawnAndConfigurePrefab()
{
instance = Instantiate(balletScript);
instance.Initialise(balletObject);
}

and it called in

[carmine iris]

I can't find this package named like Device Simulator. I checked pre version setting but still there is no packaged named like that.

[spring creek]

Where is it called though?

[plain ibex]

oh it didnt call

[spring creek]

Yep. Thus instance is never assigned

[plain ibex]

ArgumentException: The Object you want to instantiate is null.
UnityEngine.Object.Instantiate[T] (T original) (at <f712b1dc50b4468388b9c5f95d0d0eaf>:0)
Enemies.SpawnAndConfigurePrefab () (at Assets/Scripts/Enemies.cs:15)
Enemies.Start () (at Assets/Scripts/Enemies.cs:20)

line 20 : SpawnAndConfigurePrefab();

15: instance = Instantiate(balletScript);

[spring creek]

Is balletScript assigned in the inspector?

It's a prefab, so it CAN be

And MUST be

[plain ibex]

no its not prefab i cant assign it in the inspector

[spring creek]

I asked before if it was a prefab and you said yes

I really don't understand what the goal is here then

[plain ibex]

you asked is balletObject prefab

[spring creek]

This whole script is quite convoluted

[spring creek]

balletScript is not on balletObject !?

[plain ibex]

btw ballerObject isnt prefab too

[spring creek]

Why are you instantiating from something that is not a prefab
Let's start with that

[plain ibex]

idk i just instantiate from original gameobject

[spring creek]

Make it a prefab

Problem solved

[cosmic rain]

What original object? What is that object for?

[spring creek]

Using a scene object to instantiate from is risky either way. What if it gets destroyed?

Gotta be a good reason to do it that way. If not, just make it a prefab

[plain ibex]

must i change datatype of balletObject

[spring creek]

Nah, not much needs to change in code

If anything

[plain ibex]

but if i dont change i cant assign it in inspector

[spring creek]

?? Why?

[plain ibex]

because its a game object

[spring creek]

You can assign gameobjects in the inspector
Prefabs are gameobjects btw

[plain ibex]

main problem is that. i cant assign because the object that contains this script is not on scene. its only in assets

[spring creek]

Which is why you CAN assign it

Prefabs can be dragged in

No worries at all.

Prefabs cannot reference SCENE objects (like the link you sent)

But prefabs can reference prefabs

And scene objects can reference prefabs

[plain ibex]

you mean i must drag it from assets to hierarchy ?

[spring creek]

Well yes, of course

Prefabs are in the project window only

Ever

Once the object is in the hierarchy (as an actual object, not a reference), it is no longer a prefab, it is an INSTANCE of a prefab

[plain ibex]

so i dont need the codes in https://unity.huh.how/references/prefabs-referencing-components

[spring creek]

That is for the opposite of your situation

As I explained here #archived-code-general message

I gotta go to bed. Hopefully this made sense.
Good luck!

[plain ibex]

thank you very much

[latent latch]

Prefabs can reference anything part of that prefab, but they cannot reference anything else if not on a scene

it's basically a bunch of instances that exists in that prefab alone

which is why it can live outside of the scene, in your assets

Because it can live in this asset space, it means your scene objects can directly reference these prefabs in your assets, but not vice versa because a scene reference is never guaranteed as you can have many

Does sound somewhat logical that a prefab could contain scene elements because not everyone uses multiple scenes, but I guess that's just by design.

and it's not like scene object -> prefab reference is fail safe either since you can load / deload assets at runtime

[dense estuary]

I am already doing that. Since the object isnt parented to anything, localPosition is equal to worldPosition.

I am currently successfully making the object have the same rotation as the camera, and follow the camera with an offset

now I need to make it rotate around the player.

I tried using the ParentConstraint component, but its too stuttery. So I'm back to square one.

[latent latch]

There's Quaternion RotateAround

Or what kind of rotation you looking for

https://docs.unity3d.com/ScriptReference/Transform.RotateAround.html
Transform specific rotate around too

public static Vector3 RotatePointAroundPivot(Vector3 point, Vector3 pivot, Vector3 axis, float angle)
{
    Quaternion rotation = Quaternion.AngleAxis(angle, axis);
    return rotation * (point - pivot) + pivot;
}

Forgot they're is no specific Quaternion only RotateAround but this is similar that I use

usually mix it with LookAt

[slate lark]

why the player is not translating to ground?

[latent latch]

https://docs.unity3d.com/ScriptReference/Transform.Translate.html

[slate lark]

i need a detailed explanation, cause the function works(as u can see the console). but why again, the player doesn't go down (neither up)

[carmine iris]

can someone explain why this is not working

[latent latch]

The method expects a direction vector, yet you're feeding it a position vector. Look at the docs and compare that code to yours and figure out the differences.

Im surprised it doesn't throw an error as a zero direction is like imploding into yourself or some thing lol

actually, I guess that would just imply no movement since there's no magnitude anyway

[crisp folio]

so I need ground checking in my game to see if you are touching the ground or not. but when I do the ray cast it says that I'm only grounded when I look in a specific place. like if it only checks when I'm looking in a perfect number of degrees. i am very new to coding in unity and i have no knowledge on what culd be the problem. here is a snipet of my code. just ask me if you need everything:

void checkForGround()
{
    Ray ray = new Ray(transform.position, new Vector3(0f, -1.1f, 0f));
    RaycastHit hit;
    Debug.DrawRay(transform.position, new Vector3(0f, -1.1f, 0f), Color.green);

    if(Physics.Raycast(ray, out hit, 1, ~RayLayerMask))
    {
        Debug.Log("grounded " + hit.collider.gameObject.name);
        isGrounded = true;
    }else
    {
        Debug.Log("not grounded");
        isGrounded = false;
    }
}
```(this is run in Update())

[latent latch]

Try offsetting the start of the ray a few more units up on the y axis

casting usually has problems if it spawns inside of colliders

[crisp folio]

Oh ok I’ll try that. So you mean Line to spawn it above the player?

[latent latch]

it looks like the pivot is at the ground if that's where you're casting from

add a few units on the y from the transform position if that's where it's at

[hollow mantle]

hi, i've try to find the problem but i don't find it

[somber nacelle]

[lethal vigil]

has anyone had an issue with motion blur or blur in game when running the game at 30fps, when running at 60 the is no blur but of course for a mobile game 30 is better

[sly widget]

Hey, hope someone can help me. I'm having issues with my script as when an enemy is spawned, it won't move - Waypoint controller : https://pastebin.com/eAeS3B5H & EnemyMovement : https://pastebin.com/5WwqTeSH

[plain ibex]

i have a game object that moves with rigidbody2d. I want to when other objects collides with that object: that object mustn't push by other objects

how can i do it

[somber nacelle]

if you do not want the object affected by outside forces then it would need to be kinematic

[plain ibex]

thank you very muchh

[somber nacelle]

note that outside forces includes forces like gravity. and it cannot be moved with AddForce

[plain ibex]

i understood 👍

i have another problem. i want to use vector3.lerp but it works like its teleporting

wall.transform.position = Vector3.Lerp(transform.position, new Vector3(3.03f,-1.08f,0f),4f);

[somber nacelle]

yes, that is teleporting it

https://unity.huh.how/lerp/overview

[plain ibex]

i looked here but i didnt understand why have i problem

[somber nacelle]

your t value is 100% incorrect

according to that page i linked, lerping from transform.position to new Vector3(3.03f, -1.08f, 0f), what position will be returned when t is equal to 4?

[plain ibex]

-1.08f

[somber nacelle]

well no, not just a single axis. it will return the entire Vector3. because your t value is greater than or equal to 1.

[plain ibex]

ah thats true yes but i tried all of them. i made it x>1, 0<x<1 , x<0 but it teleported everytime

[somber nacelle]

you shouldn't just be using a set value for t. did you not read how it works and how you should be using it?

although perhaps you want something more like Vector3.MoveTowards if you just want to specify a speed for the third parameter

[plain ibex]

must i use them in update function

[somber nacelle]

those methods must be called multiple times in order to work the way you expect, yes

[plain ibex]

so problem was that , thanks again..

    }```
in this code i want to **finish** "if(Time.time - skillStartTime > 6)" 
and **make** lastSkillTime = Time.time 
**when** "wall.transform.position = Vector3.MoveTowards(wall.transform.position, new Vector3(3.03f, -9.05f, 0f), 0.01f);" **finishes**

how can i do?

[spring creek]

anything look wrong

You are using Find()

[gray mural]

Then P2_NameInput is found, but input is in an empty string

[gray mural]

What do you mean "when finishes"?

the code that is below this assignment happens just after the position is assigned

this is not a coroutine

[plain ibex]

so must i use coroutine for these

not update

[gray mural]

No?

What do you even want to achieve, I don't get the purpose?

[plain ibex]

i have a skill button. skill button must have a cooldown and skill must have a skill duration.

[gray mural]

Alright, that doesn't fully explain it

Skill button should be activated after buttonCooldown seconds have passed since the skill has ended, right?

Then you should probably use coroutines

[plain ibex]

yeah

[plain ibex]

thanks!

[deep path]

do you following this tutorial ?

[waxen blade]

I am trying to give the player the value of a pickup/consumable. It's already on the scene as a prefab, but you pick it up by pressing a key on the keyboard, so there's no colliders. The prefab will have a component called Loot, and in it is a method called PayOut. I want the PayOut method to give the value of the pickup.

When it's time to give the pickup to the player, I want to avoid a giant if statement that looks like:

        if (transform.name == "Coin")
        {
            //Give coin
        }
        else if (transform.name == "Heart")
        {
            //Give heart
        }
        else if (transform.name == "Potion")
        {
            //Give potion
        }

Is there a more efficient way I can do this?

[icy prawn]

you could use a switch statement

[desert blade]

or you could do some form of inheritence to further optimise it like public class Item and have a function called Collect()

[icy prawn]

switch (transform.name)
{
case "Example1":
break;
case "Example2":
break;
default:
break;
}

[somber nacelle]

please do not base logic on gameobject names

[icy prawn]

or what Unscripted said

[waxen blade]

I had a feeling someone was going to zing me on this one. I don't do it on names, that was just an example since I want to avoid an if statement.

[waxen blade]

Yeah, I think this is what I'm looking for. I don't know much about inheritance though so I need to research it some more before I can implement it. Thank you.

[icy prawn]

could also do a simple interface where you make a PickupAble with a empty method Pickup() and just make it do whatever it needs to do for certain objects

It's a lil bit simpler but not as good. Should do the job though

[waxen blade]

From what I understand, interfaces and inheritance are kind of similar.

[glass linden]

Do you think it is possible to retrieve data from the TikTok API to execute code when a live receives a gift?

[waxen blade]

I need to research both of them some more.

[icy prawn]

https://www.youtube.com/watch?v=MZOrGXk4XFI
Just a nice lil guide for interfaces with some actual examples

[dense estuary]

I tried doing that but got confused because it rotates around in the same way as Transform.Rotate(). So when I plugged in the camera rotation it zoomed around at the speed of light.

[lethal vigil]

is there anyway to stop moving objects from looking blurry if my game needs to be set to 30fps

[maiden fractal]

First of all, I see no code -> not code related issue. The speed of which objects are moving shouldn't affect the look of the game except when you have motion blur activated (TAA could also be potential problem), try to disable it and see what happens. If you need any further guidance, let's continue the conversation in the proper channel

[plain ibex]

MoveTowards and Vector3.Lerp didnt work in coroutine

they worked but

not interpolate

like teleported

public void skillButtonClick()
    {
        if (Time.time-lastSkillTime >= 20f || firstSkill)
        {
            firstSkill = false;
            StartCoroutine("SkillStarted");
        }
    }

    IEnumerator SkillStarted()
    {
        while(wall.transform.position.y < -1.08f)
        {
            wall.transform.position = Vector3.Lerp(wall.transform.position, new Vector3(3.03f, -1.08f, 0f), 3f);
        }
        yield return new WaitForSeconds(6f);
        while(wall.transform.position.y > -9.05f)
        {
            wall.transform.position = Vector3.Lerp(wall.transform.position, new Vector3(3.03f, -9.05f, 0f), 4f);
        }
        
    }```

here is my code

[lethal vigil]

Hey, i don't think it is a code issue due to the fact that when i set the FPS to 60 all movement is smooth with no blur or ghosting

[arctic plume]

Would anyone be able to help me with an issue I'm having with my code?

    void Update()
    {
        timer += Time.deltaTime;

        if (timer > interval)
        {
            timer -= interval;
            //Check that someone is actually speaking
            if (currentSpeaker != null && player!=null)
            {
                RaycastHit hit;
                if (Physics.Raycast(player.position, currentSpeaker.position - player.position, out hit, Mathf.Infinity))
                {
                    if (hit.transform == currentSpeaker)
                    {
                        eyeContactTime++;
                    }
                }
                speakingTime++;
                Debug.Log(player + " has spent " + eyeContactTime + " looking at " + currentSpeaker);
            }
        }
    }

It's supposed to measure how long the player spent looking at the active speakers whenever they were speaking, but for some reason it doesn't seem to register it at all and always results in 0
I did get a lot of the code from a Unity forum thread online so I'm not an expert at it

Also it's a VR project so player is set to the Main Camera component of the XR Rig and currentSpeaker is set to the whole model of the NPC that's speaking

[maiden fractal]

Clearly has nothing to do with code and you didn't provide one either. Please find channel that your problems fits under, if your question is general question not falling under any of the categories, use #💻┃unity-talk

[deft pilot]

this is probably because you dont have a condition that executes the function on the coroutine, its not really like Update function where it occurs every frame

[gray mural]

No, it's not because of that

[gray mural]

The Vector3.Lerp method's 3rd parameter is time, which is clamped in the range of [0, 1] and means the percent of the time used to interpolate between a and b.
When you set it to 3 or 4, it's then clamped to 1, which is 100% and interpolates between a and b at once, so basically returns b.

[deft pilot]

ahhh i see

[gray mural]

So what you do is set the wall.transform.position first to (3.03f, -1.08f, 0f), then wait 6 seconds and set it to (3.03f, -9.05f, 0f)

Which, yeah, doesn't really smoothly move the wall

[plain ibex]

in this code:
firstly it moves up direction , waits 6 seconds and after that it moves down direction.

[plain ibex]

if it doesnt really smoothly move the wall what can i do

[leaden yoke]

Is there anyone who could give me quick tips to simplify this code

I feel like im doing something majorly wrong

[somber nacelle]

the first step for getting help simplifying it is to format it in a way that is actually readable

[glossy gust]

yeah so how would I do that

cause code is code

[somber nacelle]

"code is code"

you close multiple scopes on a single line like a dozen times. you have loops and if statements nested to oblivion. comments at the end of lines instead of on the line above/below what you are commenting on, a complete lack of white space to divide up different sections of behavior

oh and you chose like one of the worst bin sites so there is almost no syntax highlighting making that even more unreadable (though that isn't really a fault of you or your code)

[glossy gust]

so how can I use less nested loops and if statements

I get what you mean by closing multiple scopes at a time to, just did that to save space for importing this into my documentation

[somber nacelle]

how should i know? your code is unreadable

unreadable == cannot be read to determine what can be simplified

[glossy gust]

what are typical ways of avoiding using so many nested loops and if statements though

I am not aware of other methods

if that makes sense

[somber nacelle]

guard statements, breaking logic up into methods, better logic

[gray mural]

You have to change the position over time

[gray mural]

practice

For instance, this condition you have

if (overlappingColliders.Contains(woodColliders[i]) || overlappingColliders.Contains(groundCollider))
{
    isPlaceable = false;
} 
else 
{ 
    isPlaceable = true;
}

can be written like this

isPlaceable = !(overlappingColliders.Contains(woodColliders[i]) || overlappingColliders.Contains(groundCollider));

or like this

isPlaceable = !overlappingColliders.Contains(woodColliders[i]) && !overlappingColliders.Contains(groundCollider);

[vast patio]

Does someone know how to code the following? Im kinda stuck at this problem, which shouldn't be that difficult...

I want a method GetObject(Transform root, name, depth) in which I want to traverse all childs of root (but max 'depth' times deep) recursivly.
If I find an object with the same name specified in the params, I return it and stop the whole function. If i find nothing I return null.

private void IterateOverChild(Transform original, int currentLevel, int maxLevel)
        {
            if (currentLevel > maxLevel) return;
            for (var i = 0; i < original.childCount; i++)
            {
                Debug.Log($"{original.GetChild(i)}"); //Do with child what you need
                IterateOverChild(original.GetChild(i), currentLevel + 1, maxLevel);
            }
        }

Something like this, but I want to return the object I find and leave the whole function, when It has a specific name.

[knotty sun]

so return Transform instead of void and add name as a parameter

[icy prawn]

what Steve said and when you find something, just "return theFoundGameObject" and it should exit the method automatically

[vast patio]

But what if it founds the object at depth 3, than it exits the 3rd function and the ones continues doesnt it?

[knotty sun]

Transform t = IterateOverChild(original.GetChild(i), currentLevel + 1, maxLevel);
if (t != null) return t;

[dense estuary]

Using this causes the object to rotate around the camera at light speed, is there a way I can make the object offset from the players forward direction?

[vast patio]

So like that?

private Transform IterateOverChild(Transform original, int currentLevel, int maxLevel)
    {
        if (currentLevel > maxLevel) return null;
        for (var i = 0; i < original.childCount; i++)
        {
            if (original.GetChild(i).name.Contains("doorAss")) return original.GetChild(i);
            Transform t = IterateOverChild(original.GetChild(i), currentLevel + 1, maxLevel);
            if (t != null) return t;
        }

        return null;
    }

[knotty sun]

best to pass name as a parameter rather than hard coding it but yes

[vast patio]

ok it works from what I see, but cant really wrap my head around it, thank you tho!

[gray mural]

Oh, so you just want to return a single object?

I have read incorrectly

[vast patio]

Yes, lets say I got this hierarchy, I call this function on Door and want DoorAssembly returned, but the hierarchy can vary, the names does not.

[plain ibex]

must i change 3. parameter ?

[gray mural]

Yes

[knotty sun]

tbh it would be better written as

private Transform IterateOverChild(Transform parent, int maxLevel, string name)
    {
        if (maxLevel < 0) return null;
        foreach (Transform t in parent)
        {
            if (t.name.Contains(name)) return t;
            Transform found = IterateOverChild(t, maxLevel-1, name);
            if (found != null) return found;
        }

        return null;
    }

@vast patio

[vast patio]

Thank you yea thats looks cleaner

[gray mural]

maxLevel-- ?

Doesn't it subtract 1 from maxLevel?

[vast patio]

yea it does

[gray mural]

So if your maxLevel is 3 and your root has 5 children, it'll just stop iterating on the 3rd one

[vast patio]

so you start with high max level and decrease it the further you go down

[icy prawn]

I think maxlevel is how deep he wants to search for i think

[vast patio]

Yea thats ok, I wanna have it as a variable

[knotty sun]

basically maxLevel becomes 'levels left to search'

[somber nacelle]

you need to copy maxLevel decrement it before the loop because otherwise it's decrementing for each iteration of the loop rather than just each depth searched

[gray mural]

Haven't you called it depth before? Shouldn't maxValue = 3 mean you cannot go 3 children deep?

[gray mural]

Yes, that's what I'm talking about

[knotty sun]

good point, code changed

[vast patio]

yea exactly, if you type in maxvalue = 3 you can go 3 children deep

[gray mural]

Yes, that's why you cannot decrease the maxValue on every child of the same root. This way you won't go depp.

[icy prawn]

btw would there even be a point to limiting how far you want to search other than for performance even though you really would like to find it?

[gray mural]

Yes, they may be sure the child is 2 levels deep, so they won't need to go deeper. Otherwise they may find a non-desired child.

[vast patio]

Yea its for performance, I know at the moment that door assembly would be 3 deep, but this could change in the future for other hierarchies I import automaticly, so I wanted to have an easy change for that

[vast patio]

Also correct

[icy prawn]

Ow ok, fair enough

[knotty sun]

it's a good idea to limit this kind of search (if you can) especialy on Canvas objects which can get very,very deep

[gray mural]

Also, I first thought you wanted to find all the children, so that's my variation of the method for it
https://gdl.space/afogocesiw.cs

[knotty sun]

also with recursive methods, one small mistake and you have a stack overflow if they are not limited

[glossy gust]

how do you do SetActive(true); on an object which doesn't have a direct reference, but only a Find("objectName") reference

can you get it's parent and then do setactive on the inactive child?

or should i just use its components

[heavy bone]

im trying to make code that follows one play er until they shoot their cannon which will switch the camera to follow the projectile and then when the projectile is destroyed it switches to the other player and so on.

i dont know the basics of unity but i have some code running that doesnt work

how would you guys make code like that?

[merry stream]

is it better to do damage numbers using vfx graph or particles, rather than instantiating, if so how

[lean sail]

if you dont have a reference to the object, you arent calling anything on it directly. the Find functions (which you really shouldnt use) literally find the object and give you the reference

[lean sail]

instead of instantiating you could use object pooling. if you need a ton of these then yea vfx graph or particles will be better

[glossy gust]

how would you guys go about making a camera which zooms out to show a wider landscape?

i just need to know the methods and I can do the rest

[ashen yoke]

change fov, dolly the camera

[dawn nebula]

So I have this chain sprite asset here. I want to be able to distort it a bit. Wiggle and jiggle with some sort of input. Is there an easy way to do this?

i already do object pool, im just wondering if there is a better option

[fast moon]

how do I use a past untiy project on github as a boilerplate for future unity projects?

I also want to to be able to update it in the future projects

something like a fork, but I can't fork my own repositories

[maiden fractal]

I'd assume the easiest way would be to use the 2D Animation Package which has a Skinning Editor feature which enables you to add bones to your 2d sprites making it possible to stretch your sprites. With the bone setup in place you can then wiggle the chain via physics simulation or via script as you wish

[buoyant scroll]

The type or namespace UI does not exist in the namespace UnityEngine, even though the package is installed.
CS0234, how do I fix this?

[somber nacelle]

is the error only in your IDE or do you see it in the unity console as well?

[buoyant scroll]

Unity console.

[somber nacelle]

are you using assembly definitions

[buoyant scroll]

I don't understand what that means

[glossy gust]

thanks

[somber nacelle]

do you have asmdef files in your folders in your project

or rather, in any folder in the path to the file with the error

[buoyant scroll]

No, I don't think so

[somber nacelle]

check

[buoyant scroll]

Alright

Like would it usually be in the scripts folder or resources folders or like

[somber nacelle]

check the folders in the direct path to the file with the error. do not bother with any unrelated folders

[buoyant scroll]

No asmdef files

[vapid lynx]

Hey im having a little bit of trouble with something. I want to create a road between two points given an array of vector3's and I can't use splines. How would i go about creating the road thru like a mesh or something idk

then show the full error message

[buoyant scroll]

one moment

Assets\Scripts\Assembly-CSharp\UIScript.cs(2,19): error CS0234: The type or namespace name 'UI' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)

[somber nacelle]

why do you have a folder called Assembly-CSharp? 🤔

[buoyant scroll]

I in my luxuriest form have no undearest clue.

the editor created it.

[somber nacelle]

it most certainly did not

[buoyant scroll]

huh

then idk

in my project its there

[somber nacelle]

i mean, yeah obviously. but it's concerning that you've got folders named after assemblies. if you move that file directly into the Scripts folder does the issue persist?

[buoyant scroll]

what do you mean

[simple egret]

Searching the internet for it, seems like it's a common thing when ripping existing games

[buoyant scroll]

what file

[simple egret]

For it to put the scripts by compiled assembly name

[buoyant scroll]

yeah, that's because i'm trying to decompile a game from a video and it didn't work

[simple egret]

We cannot help with that as it's against this server's rules

You'll have to ask elsewhere

[buoyant scroll]

oh

thank y'all for the help though

[heavy bone]

nevermind i figured it out

[glossy gust]

why is this not valid

need the child of player1 which is called fightingUI

[somber nacelle]

GameObject does not have a property called fightingUI

make your variable type the type of component you actually want to use

[merry stream]

whats the best way to work with shaders in code? say I want to turn on a highlight shader when something is hovered

[glossy gust]

its a UI canvas

what could I write for that

[somber nacelle]

Canvas also does not have a fightingUI property

[raven flare]

how can i detect whether touch input is inside of a button? it's for a mobile game revive screen where tapping the screen lowers the timer faster, but tapping the button shouldn't also make the timer go down

[glossy gust]

ohh okay, so its ab properties

[latent latch]

You can always just offset it by transform.forward * units, but you'd have to also update rotation relative to the players

could be as simple as appending the angle degrees

[cosmic rain]

You don't typically enable/disable shaders. You enable/disable objects or components that render using a shader.

[merry stream]

so in the case where I want to highlight an item on the ground when hovered, how would I do that?

[cosmic rain]

It depends on how you are highlighting it.

There are many ways to implement outlines.

[merry stream]

i made an outline shader

[faint hornet]

Hey everyone. There is a reply in this forum about the very same issue I’m having.

I want to know what the reply means.

Here is the link https://forum.unity.com/threads/unity-2d-multiple-colliders-causing-extreme-lag.643375/

I want prevent extreme lag from rigidbodies colliding, and in the reply he says something like “prevent the physics from overlapping by doing a check before moving”

I have hundreds of rigidbodies colliding and I need to keep them from overlapping (I don’t want them to stack)

[cosmic rain]

What kind of shader? Screen space? Object based? Did you follow some kind of tutorial?

[merry stream]

yes, its a sprite shader that basically takes the alpha of the sprite and shifts it 1 in all directions, then places that "behind" the sprite, creating the outline

[cosmic rain]

That doesn't answer any of my questions.😅

[merry stream]

idk its just a material 🤷‍♂️

[cosmic rain]

It's either a screen space shader or an object based shader?

[merry stream]

object based

id assume

[cosmic rain]

Okay, then you'd just add a material with the shader to the object.

[merry stream]

then remove the material when the mouse leaves?

[cosmic rain]

Yep

[merry stream]

how can I set the variables on a shader per instance

since when I change the color, all objects with that material get changed

[latent latch]

add a force around the rigidbodies for when they collide to prevent overlapping

[faint hornet]

how?

[merry stream]

do i just create a new Material witha copy constructor

[cosmic rain]

You'd need to make sure each object has it's own material instance.

[cosmic rain]

Usually unity would create a copy when you access the material via the renderer property.

[latent latch]

by using forces

[cosmic rain]

Unless you access a sharedMaterial

[faint hornet]

i'm trying to reduce the amount of physics calculations doens't that use the same resorces?

[latent latch]

isnt the issue of all colliders piling up causing lag

so if you prevent overlapping then you only deal with the surrounding colliders

[faint hornet]

no, the issue is colliders pushing eachother around

[latent latch]

if you add a force when colliders touch then you only have so many colliders touching each other

[latent latch]

it's a hard issue, but if you are using a lot of units then maybe it's best to use kinematic and object avoidance pathfind algs

[faint hornet]

this is currently how it looks and i want everything to behave the same way but with using less physics calculations

[faint hornet]

do you have a good resource for me to look up moire info on it

[latent latch]

pathfinding using navmesh

not sure how updated Unity's is, or if it works with 2D yet, but instead of moving stuff by physics you just pathfind.

It's just an option, but seeing that image I don't know why'd you get performance issues

it's not a lot of units

[slender mirage]

👋 I'm looking to create a VR Game from scratch, does anyone know of any docs that would help out with detecting the position of the headset / controllers?

[faint hornet]

oh ok ill look that up... but i have an infinite boundless world, so navmesh seems overcomplicated..

scan to the end of this video, should i do something like this? https://www.youtube.com/watch?v=SVazwHyfB7g

[slender mirage]

Ah ray based movement

[latent latch]

that's a lot of rays per unit though

pathfinding avoidance is usually done through checking if other units are on similar paths or similar destination area

[faint hornet]

well thats just before it starts tanking in performance, at about 200 obj it starts freaking out. if i make everything kinematic (allow overlapping) all the lag goes away

[latent latch]

I use A* project for pathfinding with kinematic rbs and it works pretty well as it has it's own character controller

[cosmic rain]

Are the groups of objects moving as one?

[faint hornet]

actually kinematic still causes tons of lag. at his point is when the lag hits

[faint hornet]

no, they are individual spawning in clumps

[cosmic rain]

So they can move independent from the other objects in a group?

[faint hornet]

yes

[cosmic rain]

It's not like they're stuck together?

[faint hornet]

correct

[cosmic rain]

Okay, that complicates things. Whatever approach you take, it would be heavy on performance with a large enough amount of these objects.

[faint hornet]

it's when they all get stuck together the lag hits from physics calculations among all

[faint hornet]

well how would a game like vampire survivors handle hundreds of enemies not overlapping

[cosmic rain]

The only good solution is to convert to dots.

[latent latch]

I feel like kinematic rbs would work here fine and just force stuff from each other

[cosmic rain]

I don't know if it's built with unity, but if it is, I'd assume they use dots/ECS or something similar.

[latent latch]

assuming you're just moving each unit towards the player

[cosmic rain]

Kinematic rbs would ignore collision though

[faint hornet]

i think it used not in unity and soem javascript crap

[latent latch]

you can still OnTrigger and displace others by a magnitude

[cosmic rain]

The Wikipedia page says unity(after version 1.6)

[faint hornet]

ah ok, ya last i heard about the game was when it was first released

[latent latch]

like, vampires collisional stuff is very loose and janky

it just slowly displaced units around each other

[cosmic rain]

I can see a lot of issues with that.

[faint hornet]

i agree, but it is a solution, and i'm more interested in how it's done without lag so i can make changes to the solution to better suit my game

[faint hornet]

i can see alot of issues with that as well.. i don't think i want that in my game

[cosmic rain]

But yeah, you can have ECS in any engine. It's not a unity specific pattern.

[latent latch]

yeah, it's not perfect as it would cause some erratic movement, but really similar behavior to that specific game

[faint hornet]

ECS what does it stand for?

[cosmic rain]

Entity component system.

[faint hornet]

sweet ok thanks

[cosmic rain]

Can you take a screenshot of the inspector of one of your objects btw?

Specifically when the lag occurs.

I'd also use a profiler to make sure you're interpreting the lag cause correctly.

[faint hornet]

@cosmic rain @latent latch objviously i should use object pooling to reduce some issues, but maybe thats why its cause so much lag also? physics calcs AND instantiations ? ( btw, when running the BUILD of the game, lag happens a bit later, like at 400 objs)

[latent latch]

object pool is useful when instantiation/destroying

more of an issue of calcs here

[cosmic rain]

Yeah, that's why you'd use the profiler. These kind of questions are only answerable by the profiler.

[faint hornet]

this is enemy when lag is occuring

[latent latch]

rb's are just not the cheapest for these types of games

[cosmic rain]

Okay. Maybe just make sure it doesn't check collisions with objects that you don't want it to check collisions with via the collision matrix.

[faint hornet]

here is the active profiler

[faint hornet]

all matrix is checked off except enemy default

[cosmic rain]

Use the hierarchy mode and sort by CPU time.

[cosmic rain]

It looks like the editor loop is huge though. Hard to tell from that screenshot.

[cosmic rain]

Expand it

[cosmic rain]

Do you have some logic in on collision/trigger enter or stay?

[faint hornet]

for the enemies? no

[cosmic rain]

Okay

[faint hornet]

it's only fixedupdate really

[cosmic rain]

Well, the main issue is that the physics loop is snowballing itself

You see there are 333 fixed updates in that frame.

Maybe reducing the fixed time step would help prevent it

[faint hornet]

the fixed update for each enemy

[faint hornet]

wouldn't that make enemy movement look choppy?

[cosmic rain]

No. If interpolation is working correctly. It might make collisions less precise though

[cosmic rain]

Is that an average frame though?

[faint hornet]

i reduced the fixed time step from 0.001 -> 0.02 and the lag is much smoother now

[latent latch]

Not a bad idea, I should really mess with my timesteps too

[cosmic rain]

The heck..?

[latent latch]

lol

why is the default that low

[cosmic rain]

Why was it so low?

It's not the default...

If you try making 1000 fixed updates in one second of course it will lag and snowball. Wtf lol

[faint hornet]

that's what it was set to lol

[silk narwhal]

one thing would be making new calculations on update only if a given object is within some distance and if the player moved any amount. Perhaps ditching the update() entirely for this and implementing some global callback when a player moves some distance over time, and re-calculating only then instead could improve?

[latent latch]

probably updating faster than your refresh rate

[faint hornet]

now i have this many enemies with no noticable lag

[cosmic rain]

That's not the default value. You definitely changed it at some point.

[faint hornet]

what should i make it? less often than .02?

[cosmic rain]

02 is the default iirc.

[latent latch]

.02 is the actual value

[cosmic rain]

You can make it bigger and it might help a bit more

[latent latch]

.04 should be fine

[faint hornet]

i changed it to .04 but now the bullets don't look smooth when they make contact. for example the bullet reaches an enemy and destroys itself, so most of the time it disapears before reaching the enemy... visual problem, does,t change performance

[latent latch]

try continuous discreet

[faint hornet]

looks better but now sometimes bullets pass through enemy. so not good

[latent latch]

mess around with the different mods usually

https://docs.unity3d.com/ScriptReference/Rigidbody-collisionDetectionMode.html

yeah, projectiles can be somewhat problematic at higher steps

can always just physics query it yourself is an option. It's a balance of projectiles vs enemies

assuming enemies don't move that quickly

[faint hornet]

enemies are pretty slow for the most part

[faint hornet]

i only have two modes discrete and continous

[latent latch]

if you want to do it by physics query then you'd do it via update but this requires you writing the interpolation too

just an option, but stick with a timestep that works for you right now

[merry stream]

can only one component with OnMouseEnter be present on a gameobject? it seems like the 2nd script doesnt take the callbacks

[steep patrol]

Hello, does anyone know of what type of coding it is when you calculate out a timetable of events all at once, and then try to add/edit an event that makes you have to recalculate the whole chain of events? In this particular case, I'm trying to build a tool that helps build a visual timetable of train departure/arrivals, while calculating the station crafting and showing the current storage of each station at each quarter-second of time, and any time a train changes it's departure or arrival time or a train is added/removed it has to recalculate all the figures all over.

[latent latch]

Something like an observer pattern?

Such that if something changes, then you invoke a full recalculation of everything if that's what you're asking

[silk narwhal]

not sure, but if that's what you experience, you can always create a simple MouseEventsPropagator Component like so:

[SerializedField] private UnityEvent<> MouseEntered
OnMouseEnter(){
MouseEntered?.Invoke()
}

any component you want to act on this event can be simply dragged to the invocation list in the editor. Does that help?

[faint hornet]

[fervent coyote]

Hi there;
I'm trying to make a basic circle that would output as a direction for Raycasts;

Making a unitCir: float unitCir = (360 * Mathf.Deg2Rad * (Mathf.PI * 0.1f)) * (i / maxSpawned) + Random.Range(-0.25f, 0.25f);
(In the code, the Random.Range is supposed to be a random additional degrees of angles)
Position: transform.position + new Vector3(Mathf.Cos(unitCir) * radius, 50, Mathf.Sin(unitCir) * radius)

Now, you would be saying "Why not use Random.InsideUnitCircle? And I was using that, but I realized that I wanted the absolute EDGE of a circle, and also wanted to have more control over it, as well as use it later on for directions

But right now, it doesn't seem to work correctly... Can anyone help?

[silk narwhal]

if you need an absolute edge, why not https://docs.unity3d.com/ScriptReference/Random-onUnitSphere.html and just skip the third Vector component? or maybe try just new Vector2(Random.Range(-1f, 1f),Random.Range(-1f, 1f))?

[latent latch]

I seem to hardly touch radians and just do stuff like a rotation + magnitude or vectors with a range of positions like saksiu's example

[silk narwhal]

yup, when I can I just let the engine handle those pesky radians and play around with Vectors, few videos deep, and still can't quite understand them.

I believe using the second thing I proposed, perhaps then normalizing the resulting vector (to ensure magnitude) and mutliplying by whatever you need (force) should do the trick

[fervent coyote]

I was really hoping though for it to be a perfect circle...

[cyan hornet]

Why does my Player Input not have this Jump CallbackContext ???

[silk narwhal]

If you literally want to add a random amount of degrees in some axis, you can just Random.Range(-360,360) and apply it? A perfect circle would mean drawing at almost every possible direction a set distance away from a point

[cyan hornet]

( mine is the white themed Unity )

[quartz folio]

It doesn't help that your inspector is set to Debug Mode

[latent latch]

I usually do something like:

float randomAngle = Random.Range(0f, 360f);
Quaternion rotation = Quaternion.AngleAxis(randomAngle, Vector3.up);
Vector3 randomEdgePosition = rotation * Vector3.forward * units;

Otherwise similar using Mathf cos and sin by using a random angle. I heart angleaxis.

[cyan hornet]

thanks

[fervent coyote]

Oh, I figured out
degree = Random.Range(-360, 360)
unitCircle = (degree * Mathf.Deg2Rad)
Vector3(MathF.Sin(unitCircle), 0, MathF.Cos(unitCircle))

God I love desmos for prototyping

Desmos is a life saver for math

[faint hornet]

Did you find the solution from anyone? I have my own solution that works pretty well

[silk narwhal]

you are seeing it above I believe

[fervent coyote]

Wikipedia

[faint hornet]

I have a different solution that also works. You just choose a pivot point and another point 1 unit above it use both of those to rotate x degrees. (0,360)

[fleet gorge]

Recently I found that my player was jittering as my camera movement is in Update, but the physics update happens in FixedUpdate

I changed physics simulation to happen in Update and now everything is smooth but are there any real downsides to this?

Will a person on 60hz vs 165hz have different physics?

[latent latch]

camera movement usually late update

[fleet gorge]

Ohh

How is lateupdate different from script execution order?

[faint hornet]

Fixed update is specifically for physics. Fixed update runs less often, i beleive to take more time for calculations. But idk lol someone will probably tell me I’m wrong

[latent latch]

it happens after everything resolves

[faint hornet]

Ya isn’t it the last of all update methods?

[fleet gorge]

I'll need to experiment with it

I just want the updates to happen as frequently as possible so it feels smooth

[latent latch]

cinamachine has some more options

[fleet gorge]

I'm making a platformer game so I probably won't use cinemachine 😅

[latent latch]

it's pretty much standard on all projects now

every unity template comes with it

[faint hornet]

Yeah so @latent latch helped me with understanding this more.

It depends on what you want to be smooth? Is it physics related or just vector based?

[latent latch]

(well, those with controllers added)

[fleet gorge]

It's most likely physics related; When I change player's position in Update it's smooth, but falling is still jittery

[faint hornet]

Cone machine works great for 2d and 3D. Just depends on what you want to do with the camera

[fleet gorge]

After making physics based on Update then everything became smooth

Is LateUpdate as frequent as Update?

Or is it as frequent as FixedUpdate

[faint hornet]

Are you using rigidbody2d? And it’s choppy?

[fleet gorge]

I'm using rigidbody3d and it's choppy

It's a 2.5d platformer so I used a 3d scene

[faint hornet]

Did you switch the mode to interpolate?

[fleet gorge]

Constraining the player on the z axis

[fleet gorge]

Yep and it became worse

[faint hornet]

It needs to be in fixed update

[faint hornet]

It’s in fixed update right?

[fleet gorge]

Initially I was using interpolate with rb.MovePosition in FixedUpdate

Very choppy

This was when I still based physics in FixedUpdate

[lean sail]

cinemachine has options to sync in fixed update, i dont see how a platformer would stop you from using it

[fleet gorge]

Idk I feel like cinemachine is overkill

[faint hornet]

So is the player choppy or the camera?

[fleet gorge]

The player is choppy but the camera is smooth

[faint hornet]

Do you have any forces applied on the character outside of the rigid body?

[lean sail]

"feel like" is stopping you from proceeding by just using the best free camera controller out there. Unity can be said to be overkill for a platformer

[fleet gorge]

I'm using my own gravity system, in FixedUpdate I'm applying gravity

[faint hornet]

Meaning are you using only rigid body methods or a mix?

[fleet gorge]

Only rigidbody methods

The player is only moved in FixedUpdate by rb.moveposition and rb.addforce

[faint hornet]

That’s why I think you are getting choppy. If you create your own gravity then don’t use rigid body. I beleive that’s causing a big clash

[faint hornet]

So you are adding force using the rigid body and you are applying your own gravity?

[fleet gorge]

Yep

[faint hornet]

I would put money on thats the reason for the sporadic behavior

[faint hornet]

Have you tried removing your own gravity just to test it out? Comment it out and add gravity forces in the inspector of the rigid body

[faint hornet]

I’m sure there is a way to make it work with your own gravity and the use of rigid bodies but I think that would only be beneficial if you had some kind of interesting gravity stuff like black holes etc..

What type of artificial gravity are you trying to achieve ?

[fleet gorge]

something like this

allowing you to walk on walls

[fleet gorge]

somehow still jittery

[merry stream]

yes thanks!

[runic nimbus]

@quartz folio @ashen yoke Thanks

[slim aspen]

I have a standard camera controller that rotates the camera using x and y values controlled by inputs.

How do I modify those values using math to make it look at an object automatically?

LookAt() is something I want to avoid, because after something happens (eg. first-person in-game NPC diaglog/cutscene), the camera will simply snap back to the x and y values that were set before it disabled in favor of said "something"

[latent latch]

so the problem with LookAt is it's instant?

https://docs.unity3d.com/ScriptReference/Quaternion.LookRotation.html

With
https://docs.unity3d.com/ScriptReference/Quaternion.Slerp.html
or
https://docs.unity3d.com/ScriptReference/Quaternion.RotateTowards.html

[slim aspen]

No, the problem with LookAt is it's not the camera controllee that is moving:

1. Look at 270° degrees using mouse (camera controller)
2. NPC calls you from 90°
3. Camera controller is still looking at 270° before being disabled
4. LookAt can finally overwrite the rotation, making the camera "look" at NPC at 90°
5. Cutscene ends and the LookAt script disables
6. The Camera controller re-enables and snaps player back to 270°

this is the scenario I'm trying to avoid

[slim aspen]

ok I'll try and take a look

[latent latch]

oh wait those are the vector versions

Need the quaternions

yeah, basically you have Sleerp or RotateTowards in your late update constantly reading at the current target rotation

you can override it and it will just pick up at that rotation (but there's a different between these two methods, Slerp is specific timing while RotateTowards is a constant speed)

[royal gulch]

What are the best practices for instantiating prefabs during runtime?

For my previous project, I made a PrefabCache class and stuck it on an empty gameobject and added all my prefabs as public serializefield variables in that class so that other scripts can access the prefab they need.

After reviewing my project based on what I've learned, this method seems wrong. Is using Resource.Load the better way to grab and instantiate prefabs during runtime, or is there some design pattern I can implement?

[latent latch]

prefabs and SOs (mostly any constructed asset instance) I like to throw IDs on and stick em into lookup tables

[royal gulch]

when creating a lookup table, is there a specific unity feature that I should look into using, or is it just a plain dictionary data structure?

[latent latch]

Dictionaries solve everything

The reasons I do it this way is for serialization purposes (loading, saving, networking), such that I do more dependency injection than having the assets constructed

[royal gulch]

Okay, thank you. I will try this approach in my next project

[desert jackal]

I'm stuck. Trying to snap to ground, but it only works when I don't specify probeDistance in Physics.Raycast.
When I specify probeDistance [ if (!Physics.Raycast(body.position, Vector3.down, out RaycastHit hit, probeDistance)) ], it doesn't detect ground, no matter what distance I use.

[plain ibex]

my unity crashes when i click a button how can i detect the reason

its about code

[latent latch]

https://docs.unity3d.com/Manual/LogFiles.html

[dawn nebula]

So I have a 0 to 1 value. I want to pick 2 times during a day (like 6am and 2pm) and be able to lerp between them using this number. Any tips?

[mellow sigil]

Use a 24-hour clock and lerp like you'd normally do. Mathf.Lerp(6, 14, t)

[plain ibex]

while(elapsedTime < 2f) {
                foreach (GameObject aE in activeEnemies)
                {
                    aE.transform.localScale = Vector3.Lerp(aE.transform.localScale, new Vector3(1.5f, 1.5f, 1f), (elapsedTime * 0.5f));
                }
                elapsedTime += Time.deltaTime;
           }```

lerp doesnt work

its changing but not smooth

not interpolate

[faint hornet]

can someone tell me why task is spawning all my enemies at the same time instead of in intervals?
I figured out that it works correctly when i put the local varable 'spawninterval' outside of it's scope but not as a local?? so confused

async Task StartRally()
  {
    isRallyActive = true;
    float elapsedTime = 0f;
    float spawnInterval = 0f;  <========================= NOT WORKING AS A LOCAL VARIABLE

    while (elapsedTime <= 120f)
    {
      elapsedTime += Time.deltaTime;
      if (spawnsPerMin == 0 || !isRallyActive) return;

      if (spawnInterval == 0f)
      {
        SpawnEnemyGroup();
      }

      spawnInterval += Time.deltaTime;
      spawnInterval = Mathf.Clamp(elap, 0f, rate);

      if (spawnInterval >= rate) spawnInterval = 0f;

      await Task.Yield();
    }
  }

[cosmic rain]

Because you're using lerp incorrectly. Check the docs to understand what the third parameter is and what value it's supposed to have.

[cosmic rain]

You're not yielding inside the whole loop. I'd assume that it's related to the issue.

[plain ibex]

i read it. it says when third parameter equals 1f it equals to second parameter. and when third parameter equals 0f it equals first parameter

so i increased third parameter to 1f

with while

but why didnt work i dont understand

[faint hornet]

im yielding at the bottom of the while loop?

[cosmic rain]

Well, try calculating the value that the third parameter has every frame with your shared code. And how it affects the result.

[faint hornet]

so i shoudl do it like this?

async Task StartRally()
  {
    isRallyActive = true;
    float elapsedTime = 0f;
    float spawnInterval = 0f;  <========================= NOT WORKING AS A LOCAL VARIABLE

    while (elapsedTime <= 120f)
    {
      elapsedTime += Time.deltaTime;
      if (spawnsPerMin == 0 || !isRallyActive) return;

      if (spawnInterval == 0f)
      {
        SpawnEnemyGroup();
      }

      spawnInterval += Time.deltaTime;
      spawnInterval = Mathf.Clamp(elap, 0f, rate);

      if (spawnInterval >= rate) spawnInterval = 0f;

       yield return null;
    }
    await Task.Yield();
  }

[cosmic rain]

What's the point of it? You know that code runs line by line as fast as it can? Your while loop completes in the same frame.

[faint hornet]

what do you mean whats the point. its a task that lasts 120 seconds. but every 6 seconds ( in the while loop) enemies are spawning.

[cosmic rain]

You need to await in the while loop instead of in the end of the task.

[faint hornet]

look at my original post, that's how it was!

[cosmic rain]

Ah, okay. I thought the await was outside the loop.

[faint hornet]

like i stated in the original post.. the task works properly when i have that local variable outside of the method ( globally) but when the variable is local ( like in the post) it doesn't work. why?

[cosmic rain]

Why does it have a value of 0?

Does it have a different value when defined outside the task?

[faint hornet]

that is the starting value

[cosmic rain]

Ah, nvm was looking at a different variable.

[faint hornet]

wait, ill simplify the code by removing redundant code. 1 sec

[faint hornet]

float spawnInterval = 0f; <================== This works here.
async Task StartRally()
  {
    isRallyActive = true;
    float elapsedTime = 0f;
    float spawnInterval = 0f;  <========================= not working here.

    while (elapsedTime <= 120f)
    {
      elapsedTime += Time.deltaTime;
      spawnInterval += Time.deltaTime;
      spawnInterval = Mathf.Clamp(spawnInterval , 0f, rate);

      if (spawnInterval >= rate) spawnInterval = 0f;

      await Task.Yield();
    }
  }

[cosmic rain]

What's elap?

[faint hornet]

omg that's the issue

how did i not see that

[plain ibex]

i calculate it and im sure there is no problem with third paremeter

interesting

[faint hornet]

oh wait no. my code isn't like that. that's not the issue

[cosmic rain]

Calculate it on paper.

[cosmic rain]

Then how is your code?

[faint hornet]

i just updated it. look up

[faint hornet]

elap is supposed to be the 'spawnInterval '

[mellow sigil]

There's nothing in your code that would spread the effect over multiple frames. The while loop runs to completion immediately.

[latent latch]

if you're using a coroutine you're suppose to yield with the while loop

if you're not using a coroutine, why are you using a while loop

[faint hornet]

i'm using async Task. you can see it at the top of my code block

[cosmic rain]

Can't see anything abnormal then. It should work as a local variable.
How are you testing it now though? I don't see any spawning code anymore.

[faint hornet]

i removed the spawning code so you could focuse on the weirld issue with vfariable placement

[cosmic rain]

Can you replace it with a debug log and share the full code?

And test of course

[faint hornet]

this is the full code that doesn't work

async Task StartRally()
  {
    isRallyActive = true;
    float elapsedTime = 0f; 
    float spawnInterval = 0f; <++++++++++++++++++++++++

    while (elapsedTime <= 120f)
    {
      elapsedTime += Time.deltaTime;
      if (spawnsPerMin == 0 || !isRallyActive) return;

      if (spawnInterval == 0f)
      {
        SpawnEnemyGroup();
      }

      spawnInterval += Time.deltaTime;
      spawnInterval = Mathf.Clamp(elap, 0f, rate);

      if (spawnInterval >= rate) spawnInterval = 0f;

      await Task.Yield();
    }
  }

This is the full code that DOES work

float spawnInterval = 0f; < =====================

async Task StartRally()
  {
    isRallyActive = true;
    float elapsedTime = 0f;
    

    while (elapsedTime <= 120f)
    {
      elapsedTime += Time.deltaTime;
      if (spawnsPerMin == 0 || !isRallyActive) return;

[plain ibex]

this is a coroutine

in a coroutine

[latent latch]

ya need to yield then

[plain ibex]

return null ?

[faint hornet]

if i need to yield ( the way you say i should ) then why is the second block of code working?

[faint hornet]

i have to return null for local variables? doesn't make sense

[latent latch]

replying @plain ibex
But yes, return null as it'll go back into it next frame

[cosmic rain]

Why is it elap again..?

And where is the debug log?

[plain ibex]

 while(elapsedTime < 10f) {
                foreach (GameObject aE in activeEnemies)
                {
                    aE.transform.localScale = Vector3.Lerp(aE.transform.localScale, new Vector3(1.5f, 1.5f, 1f), (elapsedTime/10f));
                }
                elapsedTime += Time.deltaTime;
                yield return null;
           }```

i place it like this but didnt work

[faint hornet]

AHHH "elap" was the issue... omg. so elap was the global variable that i was replacing for 'spawnInterval'. i missed that, and the whole thing wasnt working

it's fixed. thank you @cosmic rain i knew it was something stupid lol most of my errors are like that haha

[latent latch]

looks fine to me honestly but I need to see the full code

if it's a coroutine inanother coroutine then that's somethign to consider

[plain ibex]

private IEnumerator SkillLerp(float time)

[latent latch]

what's the point of everything below what you're lerping

keep it simple for now, and try to get that piece of code from before working

then continue adding more logic

[plain ibex]

private IEnumerator SkillLerp(float time)
    {
       float elapsedTime = 0;
       while(elapsedTime < 10f) {
                foreach (GameObject aE in activeEnemies)

                    aE.transform.localScale = Vector3.Lerp(aE.transform.localScale, new Vector3(1.5f, 1.5f, 1f), (elapsedTime/10f));
                }
                elapsedTime += Time.deltaTime;
                yield return null;
           }
}```

[cosmic rain]

So, what's the issue now? Does this not work?

[plain ibex]

its working but as i said lerp dont effects to it

[cosmic rain]

Wdym?

[plain ibex]

it changes localScale not interpolate

not smooth

it changes directly

third parameter is true

im sure

[cosmic rain]

Ah, well you might need to cache the starting value of lerp for each object and use it in lerp.

[faint hornet]

@cosmic rain do you know why this isn't working?
so the game isn't freezing up or anthing, it's currently just not running the RallyCountdown Function. when it gets to the while loop nothing executes after that.

async Task RallyCountdown(float duration)
  {
    float elapsedTime = 0f;
    while (elapsedTime < duration)
    {
      currentRally.CountDownText(duration - elapsedTime);
      elapsedTime += Time.deltaTime;
      elapsedTime = Mathf.Clamp(elapsedTime, 0f, duration);

      if (elapsedTime > duration) return;
      await Task.Yield();
    }

  }

  async Task StartRally(float countdownDuration)
  {
    isRallyActive = true;

    await RallyCountdown(countdownDuration);

    float elapsedTime = 0f;
    float spawnInterval = 0f;
    while (elapsedTime <= 120f)
    {
      elapsedTime += Time.deltaTime;
      if (spawnsPerMin == 0 || !isRallyActive) return;

      if (spawnInterval == 0f)
      {
        SpawnEnemyGroup();
      }

      spawnInterval += Time.deltaTime;
      spawnInterval = Mathf.Clamp(spawnInterval, 0f, rate);

      if (spawnInterval >= rate) spawnInterval = 0f;

      await Task.Yield();
    }
  }

[cosmic rain]

Add debug logs to see what's going on. Or use the debugger.

[faint hornet]

also no errors are occuring

[faint hornet]

i did use debug. everythign is working up until the while loop. i just removed the logs

[cosmic rain]

Don't remove logs when sharing code. Add logs to inside the while loop as well

[plain ibex]

Isn't it already doing this? If not how can I do it?

[faint hornet]

ok but how to logs help you? doesnt that just clutter up the block of code for you to see?

[cosmic rain]

No. Lerp interpolates between value a and b, but your value a is changing constantly resulting in a non linear interpolation.

[cosmic rain]

It helps me see what you tried and I can ask you if you see certain logs in the console.

[plain ibex]

ahh so problem is i wrote to a transform.localScale

[quartz folio]

How are you calling StartRally?

[plain ibex]

@cosmic rain now it isn't scaling

not directly scaling too

omg i did it but how i dont know

haha

[merry stream]

when implenting the builder pattern, is it better to create a seperate class "xBuilder" or just make all the methods in the class itself

[thin aurora]

Separate class, that's the point of a builder

otherwise you just have some variant of a fluent api

The point is that the builder exposes specific functions, and after building you will have a class that doesn't expose any of these type of methods

[merry stream]

so declare the builder nested in the class so it has access to its private members?

[thin aurora]

I'd say make a separate public builder with public method and private variables.
When you Build() your builder it creates a new instance of your class through an internal constructor so nothing else but other internal classes can call this.

It's what i did

Then the builder maps the variables into the class through the constructor

[merry stream]

can you give me an example?

[thin aurora]

1 sec

I'll share mine, but I have to strip it a bit

Pseudocode of a builder to define an event that can be scheduled https://gdl.space/zezevujifu.cs

In my case I could also add an internal constructor to ScheduledEvent so nobody can manually create one, but you need to specify all the types anyway

[merry stream]

ive never used sealed or internal, what do those do again?

[thin aurora]

I don't think Unity supports required keyword on properties yet so you should probably make a constructor instead

[thin aurora]

sealed indicates the class can't be inherited from, internal indicates the class, method or property can only be accessed by things in the same assembly.

usage:

var schedule = ScheduledEventBuilder.Create<ServerDataFetchJob>(nameof(ServerDataFetchJob))
    .StartImmediatley()
    .WithRetry(3, TimeSpan.FromSeconds(5))
    .Build();

[merry stream]

if I have everything in the base assembly, does internal not change much?

should I avoid having everything in that main assembly?

[latent latch]

pfft sealed and im over here making all my methods virtual and protected just in case

[quartz folio]

sealed does give extremely minor performance boosts 😉

[thin aurora]

C# should enforce sealed by default

[thin aurora]

It doesn't

I wrote this code in a separate project so it does affect it in my case

This is a scheduler system so it's more organising to put this in a separate project.Scheduler project for me

Also clears up how much can actually be modified by outside sources

[wild warren]

in unity i fetch back users profile picture from a url, then download it and turn it into texture to display it and assign it to a raw image, but getting back this texture takes alot of the devices ram, especally in IOS and makes the ap crash, what should i do to reduce the size of the texture ??

[knotty sun]

show the !code for CropTexture. Why are you calling it 3 times?

i'm calling it 3 times because i have three diffrent raw image which i want to take this texture

and the code for crop texture is for making all the images square

[knotty sun]

SO you are taking one Texture and producing 3 duplicates

[wild warren]

yes

[knotty sun]

you only need to do it once and then apply the resulting Texture where it is needed

[wild warren]

and thats what i'm doing i get back the texture once in start and giving the result to 3 raw images to be displayed in three places

[knotty sun]

no, that is not what you are doing
you take one texture from the web and make 3 copies of it when you don't need to

[gaunt nexus]

how do i add an element to an array
without doing array[x] = element
like just add it to the end

because i wanna make a spawn limit to my enemy spawner

and wanna add the enemies to an array

[knotty sun]

you use a List rather than an Array

[gaunt nexus]

well time to learn a new thing

[merry stream]

a list is just an array with fancy methods

[wild warren]

okay i will fix that but lets back to the main issue, some of these images have a very high quality, how can i reduce it , for example in the editor when i have an image i can edit max size, how can i do that in code

[gaunt nexus]

uhh welll when the game object gets destroyed the list count dosent go down

how do i fix that

[latent latch]

If you destroy a game object you need to still remove it from the list

[gaunt nexus]

i thought that would happen automatticly

[latent latch]

Either by using Remove, or by setting the index null, but unless you're dealing with fixed capacity you should just Remove

[gaunt nexus]

how am i gonna remove tho

[latent latch]

Ideally what you want to do is first remove it from the list and then destroy it.

[gaunt nexus]

idk how to do that 😵‍💫

i have this in 1 script

but when i tried this in another one

it said object refrence not set to insttance of an object

[somber nacelle]

most likely your spawner variable is null

[gaunt nexus]

how can i be so foolish 🤦‍♂️

it is not changing enemySpeed

[mellow sigil]

foreach (GameObject aEs in activeEnemies)
{
    enemies.enemySpeed = 2f;
}

These loops make no sense

It loops through activeEnemies, completely ignores them, and sets an unrelated variable's value every iteration

Do the objects with the Enemy tag have the Enemies component?

[plain ibex]

yes

so it must work

idk why it isnt working

[mellow sigil]

What makes you think that enemies.enemySpeed is in any way related to activeEnemies?

[plain ibex]

yes youre right but over this foreach loop, i wrote "enemies.enemySpeed = 2;" again.

why it isnt working too

[mellow sigil]

Yes, and it changes a completely unrelated variable

[plain ibex]

enemies.enemySpeed=2f means new instantiated enemies will have 2f enemySpeed because they have Enemy script. am i wrong

but it doesnt

[mellow sigil]

you are wrong

[somber nacelle]

you are wrong because that is an instance variable so unless you are changing that value on the prefab (why would you do that) or on the instantiated objects, then it is entirely unrelated to the newly instantiated enemies

[plain ibex]

i do that because i want two things:

• active enemies speed must change
  _ new instantiated enemies speed must change

[somber nacelle]

and your Enemies.enemySpeed variable appears to be entirely unrelated to any of this

show me a single line where you actually use its value

[plain ibex]

rb.velocity = new Vector2(7.75f - transform.position.x, randomTowerY - transform.position.y).normalized * enemySpeed;

[mellow sigil]

enemies.enemySpeed has nothing to do with the active enemies. Changing it won't change the speed of active enemies

[somber nacelle]

show the full context. because from what you showed before that line does not exist in the same class

[plain ibex]

yea but it also dont changes new enemies too

[mellow sigil]

Active enemies are in variable activeEnemies and each individual enemy is in the variable aEs. Neither of those has any link to the enemies variable.

[somber nacelle]

I see that Enemies spawns the BalletScript object. but BalletScript modifies the Enemies.enemySpeed variable. are these components perhaps on the same object?

[plain ibex]

not on the same object

enemies script in enemies prefab

[somber nacelle]

well something is fucky here that you aren't showing. but you also only assign to velocity a single time, never after the enemySpeed variable has been updated

[plain ibex]

its the full code.

[plain ibex]

must i assign it on start

[somber nacelle]

it's obviously not all of the related code considering you never show where any of the enemy objects are spawned, it's also not the full context because you also don't show what is assigned to the enemies variable on BalletScript (which you also haven't shown the full code for)

[somber nacelle]

if you plan to change the velocity after the object has already started moving, then you need to assign it in more than just Start

    }
}```
2: it assigned to enemies script that in one of prefabs (i have 3 different enemy prefab but all of them have enemies script)

[somber nacelle]

so you change it on one of the prefabs and expect it to affect all of them? and also you expect it to affect the instances in the scene that are now entirely unrelated to that one prefab?

#archived-code-general message
#archived-code-general message
#archived-code-general message

[plain ibex]

i think so because all of them have same script

[somber nacelle]

again, that is incorrect

you can't change a variable on the prefab and expect every instance of the component that variable is on to also change. if you want all of them to have the same speed at all times, you could make the variable static. then make sure to update the velocity each time you change the variable

of course you should probably also learn the difference between static and instance members before you do that

[knotty sun]

you do realize that this

if (scaleSkill)
        {
            lastEnemy.transform.localScale = new Vector3(1.6f, 1.6f, 1f);
        }

will never execute

Hey there! I've been facing an issue with my Unity project. I installed 'Microsoft.ML.OnnxRuntime', 'Microsoft.ML', and their related packages via NuGet Package Manager in VS Code. However, whenever I reopen my Unity project, the .csproj file seems to revert back to a state where these packages weren't included. Any advice on how to ensure these package references persist across sessions? Thanks

[chilly surge]

Unity does not natively support NuGet, you cannot add NuGet packages like you normally do with regular .NET projects.

[knotty sun]

load the NUGet packages into a regular VS .Net solution then copy the .dll files into your Unity project in a Plugins folder

[chilly surge]

You can either manually install NuGet packages by extracting the dll and putting them in your project assets, or use a NuGet integration for Unity.

[karmic flame]

I will try that so
first: i just need to manaully download a Microsoft.ML.OnnxRuntime.dll and
second: then place it in plugin folder then
third: download the Microsoft.ML.OnnxRuntime again from Nuget Package manager inthe vs code?

[chilly surge]

You don't need to do the third.

[karmic flame]

Okay thanks!! Lemme try it!!

[chilly surge]

When you put a dll in Unity, it regenerates .csproj (or at least it should, if it doesn't then you can do it manually) to make it work.

[rain minnow]

no, you can have multiple components using the method . . .

[nocturne wyvern]

Hello, I'm testing firebase authentication.

Now when I try to login it says first

LoginFailed : An internal error has occurred.

then I call the method again and it already writes

LoginFailed : We have blocked all requests from this device due to unusual activity. Try again later.

Does anyone have any ideas on how to fix it? I'm testing on a laptop

[long hare]

why sometimes while the player is wall sliding he get stuck to the wall ? (is it the script issue or the collider?)

I didnt find any issue with the colliders

[deft timber]

how can we know if its a script issue if you didint even share your code?

[trim schooner]

this is a code channel... delete and ask in #📲┃ui-ux

[frosty surge]

alright

[glossy gust]

I made a grid lock but it isn't working anymore despite the logic and code seeming all perfect

I believe the issue came after I mixed the UIs and scene elements, but I cleared the parents and the grid lock is still not working

[somber nacelle]

see #854851968446365696 for what to include when asking for help. nobody could possibly know what the issue is since you've provided no context

[glossy gust]

I have a build boundary with a box collider, and within the 'placeholders' parent object, I have two placeholders which follow the mouse when I am spawning them via the UI. anyways spawning the placeholders work but the grid lock doesn't.

this script generates the grid, the tags are applied correctly

the boundary collider in this script is what I want to check, it has been referenced correctly in the inspector

if you need more context ill give it, I will go through any troubleshooting tips. Thanks 🙏

[leaden yoke]

is visual studio code better or visual studio? using it to doing in c# in for unity

[chilly surge]

Both are fine, but if you are not familiar with Unity/development in general, VS is recommended because most tutorials online use VS.

[latent latch]

I use both

vs for the tools, debugger, ect. VS code for the glorified notepad

[chilly surge]

I use VS Code exclusively, it also has debugger and what not.

[latent latch]

oh huh I thought that was exclusive to vs

[chilly surge]

Nope, a lot of people seem to have the impression that VS Code is bare bone and has nothing. It has language server so intellisense/autocomplete/diagnostics/etc, debugging works and all the things you expect with debugging like breakpoints/viewing variable values/etc.

One of the engineers in the C# language design team who frequents the C# Discord server, works with VS Code for developing the language too.

it eats 5 less gigs of my mem that's for sure

[chilly surge]

Yeah and it's nice that VS Code opens instantly. Whenever I accidentally click "open in VS" instead of "open in VS Code" I just have to roll my eyes and wait for VS to slowly load before I can even close it.

[latent latch]

I just use it for HLSL and some OpenGL stuff but ill probably look into it more eventually since I heard the unity support has been improved since

[chilly surge]

Although for how much I enjoy VS Code personally, for anyone that asks the question "what should I use," I will always recommend VS. VS is just generally much nicer for beginners that need hand holding, and especially almost all the tutorials online are written assuming you use VS.

it seems like the ground check is extremely inconsistent, even on a terrain collider its unusable.

it even turns to false when im just standing still. any idea why this could be happening?

[glossy gust]

[karmic flame]

Didn't look that close, but if you instantiate something in a spot and then try to rely on OnTriggerEnter, i don't think it'll work. Things aren't "entering" the trigger. They would already be inside it.
Didn't see if you were actually moving it though

Hello, I am currently trying to change the Rect Transform dynamically at runtime depending on my element count. Can I somehow limit the max transform height? I want to match the size with the elements.

layout groups + content size fitter @void ferry

yo guys, why does my player not jump?

[dull glade]

I really getting pissed at unity, for some reason my public var doesn't show up in the inspector no matter what I do!?

[fringe ridge]

what type is it?

[dull glade]

Its an animation curve

[fringe ridge]

First of all, where do you call jump?

is animation curve serializable?

[dull glade]

yes

[fringe ridge]

i don't think it is

okay, yeah, maybe it is

[dull glade]

Ok I worked it I needed to be in debug view, thanks a lot lunity

[cyan hornet]

I added Jump(); in the Update... and now I get this:
Assets\Scripts\PlayerController.cs(35,9): error CS7036: There is no argument given that corresponds to the required formal parameter 'context' of 'PlayerController.Jump(InputAction.CallbackContext)'

I got this Input Action here inside of my Player Capsule though so that should be it
