Things they do for consistency

[vivid halo]

Fair

[leaden solstice]

The Zen of Python

[knotty sun]

tbh the whole argument is moot. In a team you use the convention of the team. For yourself you do what you want because nobody else gives a shit

[vivid halo]

To be a pedant, following the convention of the community makes collaboration easier and more seamless.

[knotty sun]

not the way teams work. the project leader is the boss as far as this is concerned because, at the end of the day, it's his ass when the shit hits the fan

[leaden solstice]

Unless you are working on C++ which doesn't have "official" convention

[vivid halo]

If it's a personal project or you're the team lead, then you're boss

Which I think is a very common scenario for a lot of us here

[knotty sun]

yep and no one gives a rats arse what you do

[vivid halo]

If I coded like an ape, I think people would help me less

[knotty sun]

what makes you think you don't?

[vivid halo]

I follow convention, use a linter, and I have seen my code from 6 months ago

[heady iris]

if your project survives long enough, your old work starts feeling like someone else's work (:

so I try to be nice to my future self

so far I have been moderately successful

[knotty sun]

but that is still 'just' your opinion

[vivid halo]

It is my opinion that using Assembly is a bad choice to program a game

It is subject to disagreement, however.

But it is plain and obvious to most

The existence of a continuum between bad code and good code doesn't mean good code doesn't exist

[knotty sun]

really? You would never have survived the '70's

[vivid halo]

Assembly has not survived for game development beyond novelty projects, and for that I am grateful

I once met another code wizard that coded network protocols in Assembly before the invention of TCP/IP

Mind-boggling

[knotty sun]

well, we still write device drivers in ASM and without them you wouldn't have nice new bright shiny toys to play with

[vivid halo]

Embedded engineers are to me what software engineers are to average people. Touching assembly is ugly. How they manage to stay organized is beyond me

[knotty sun]

like anything else, practice, practice, practice and a damn good memory

[vivid halo]

What about massive systems where the scope of the project far exceeds memory? There are no convenient organizational features I'm aware of. It seems like no-man's-land for code

[knotty sun]

there are ways, but not convenient, one project I worked on which had thousands of scripts files used a numbering sequence for organisation. not nice but it works

[pine bobcat]

Hello, sorry for interupting here but is there anyone who could help me with my scene colors?

I see only yellow color in scene

[knotty sun]

does not sound like a code problem

[fallow quartz]

if I have this code to move a platform it should be consistent right? Because its on the fixedupdate but idk why its not. I have a platform at 5 speed with 2 points and never bugs out and then i have another with 4 points making a square at 3.5 speed which is less and it just goes to the infinity and doesnt follow the path:

void FixedUpdate()
{
rb.velocity = moveDirection * speed;

    if (Vector2.Distance(transform.position, points[nextPlatform].position) < 0.1f)
    {
        nextPlatform++;
        if (nextPlatform >= points.Length)
        {
            nextPlatform = 0;
        }
        directionCalculate();
    }

}

private void directionCalculate()
{
   moveDirection = (points[nextPlatform].position - transform.position).normalized;
}

[restive ridge]

does gravity calculation differ based on whether im using root motion or not?

[heady iris]

You calculate the direction to move in FixedUpdate

The rigidbody then moves in the physics update (which happens after FixedUpdate)

Suppose it's going right, and then starts moving up

If it overshoots the point, it'll be too far to the right

it might even be moving slightly to the right, too, since you calculated the move direction before it made its last move to the right

when it was still a bit to the left of its destination

[fallow quartz]

so what i should do? I noticed if the platform is going only in 1 direction like up and down or right and left it doesnt happen

it just happens on the ones that goes in a rectangular way

[heady iris]

this is what's happening

i'd suggest doing two things

calculate the move direction every FixedUpdate, so that it will correctly move towards the destination

i'd also clamp the velocity based on how far away the destination is

so that you don't overshoot it

you could also just use Vector2.MoveTowards to calculate a new position and then pass that to rb.MovePosition

that way, you never overshoot a point

[fallow quartz]

yeah taking the direction calculate at the end of the fixedupdate seems to have fixed the problem

[fallow quartz]

Btw when i was with the update it occurs sometimes but in fixedupdate the bug is consistent, this means if now is working properly on fixed it will always do?

[heady iris]

It's still possible to overshoot the goal if you only fixed this part

it's just less likely, since you are always moving straight towards the target

[fallow quartz]

how could it still happen if the direction is being calculated all the time?

[fallow quartz]

overshoot the goal means it could happen right?

[gray mural]

Is there any way to move a YieldInstructor as IEnumerator?

It's confusing that it's not even derived from it

[heady iris]

notice that you use IEnumerator when writing a coroutine

not, say, IEnumerator<YieldInstruction>

you can yield literally whatever you want

Unity checks if the value you provided is an IEnumerator, a YieldInstruction, etc.

[gray mural]

I don't want to yiled it, I want to MoveNext it manually instead

I can't seem to be able to get the seconds from WaitForSeconds to await it

[heady iris]

you can't, because a YieldInstruction is not an enumerator

I'm pretty sure that WaitForSeconds is handled entirely on the native code side

[StructLayout(LayoutKind.Sequential)]
[RequiredByNativeCode]
public sealed class WaitForSeconds : YieldInstruction
{
    internal float m_Seconds;

    //
    // Summary:
    //     Suspends the coroutine execution for the given amount of seconds using scaled
    //     time.
    //
    // Parameters:
    //   seconds:
    //     Delay execution by the amount of time in seconds.
    public WaitForSeconds(float seconds)
    {
        m_Seconds = seconds;
    }
}

given that this is the entire class

[gray mural]

Yeah, and the seconds are internal

[heady iris]

You can pull them out through reflection, of course

[gray mural]

Oh, sounds interesting

[heady iris]

What are you trying to make happen?

Are you trying to recreate how coroutines run?

[gray mural]

Yes, quite what I'm trying to do

[heady iris]

You'll have to do what Unity winds up doing: check if the value is a WaitForSeconds, an IEnumerator, a CustomYieldInstruction, etc.

[leaden solstice]

I think they have something like

if (e.Current is WaitForSeconds w)

[heady iris]

it's icky, but that's what happens when you're getting handed an object :p

[gray mural]

I'm trying to make a StartCoroutine method, which, #if UNITY_EDTOR, runs my method with asyncs, otherwise calls MonoBehaviour.StartCoroutine

[leaden solstice]

Just use async tho

It works same as coroutine if not better

Still runs on main thread (because Unity magic)

[gray mural]

Do you mean not implementing a custom StartCoroutine method or simply using async instead of the Coroutines?

[leaden solstice]

Yes

[gray mural]

There are 2 options

Which one are you referring to?

[leaden solstice]

not implementing a custom StartCoroutine method and simply using async instead of the Coroutines

Why they are separate options

[gray mural]

And so I can get that m_seconds using reflection if it's WaitFroSeconds?

[heady iris]

Yeah.

[gray mural]

I'm sorry, I meant "not calling the MonoBehaviour.StartCoroutine method in my own StartCoroutine"

And, I mean, I don't think async should be used if we already have coroutines on run time

[leaden solstice]

Why? Async is more brand-new and Coroutine is just there because async wasn't exist when Coroutine was introduced.

[gray mural]

I don't think awaiting a task delay is more accurate though?

And Unity doesn't support .NET 6 for periodic timer

[leaden solstice]

Accurate in what sense? You can just check with timer or use Awaitable.WaitForSecondsAsync if you're on supported version.

Or use UniTask they should have equivalent

Only inaccuracy is that game time might differ from what Task.Delay checks

Not the problem with async-await

[fallow quartz]

I have a problem. When i dash with my player, if after the dash im inside the panda collider he will just push me down the ground, is there any way to fix this?

[lean sail]

Have you asked the panda to lose some weight? There isnt really enough info to go off here besides saying your dash shouldnt put you inside another collider to begin with

[fallow quartz]

my dash makes me avoid all collisions with enemies until it finishes

[lean sail]

A lot of this depends how you're actually moving. You could compute depentration if via physics and try to move the player outside the area

[fallow quartz]

thats my playerMovement

ofc it only happens if the hitbox is big, if its from an enemy from my size it will just hit me into one side

[shy knoll]

How can i add a "trail" that shows where the player is going too land?

{
    Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
    mousePosition.z = 0;
    Vector2 direction = (mousePosition - transform.position).normalized;
    float appliedForce = Mathf.Lerp(minJumpForce, maxJumpForce, Mathf.Clamp01(holdTime / maxHoldTime));
    rb.AddForce(direction * appliedForce, ForceMode2D.Impulse);
}```

like in angrybirds

[rigid island]

trajectory ?

[leaden solstice]

You wanna predict where the character will land?

I think that is usually done with many raycasts as physics involved 😄

[shy knoll]

Yes

[shy knoll]

Yes

[shell scarab]

if (normalizedDistance >= 0.5f) // start at half the distance
{
  //float dot = Vector3.Dot(toCenter, spawnPoint);
  
  Quaternion spawnFacing = Quaternion.LookRotation(spawnPoint, Vector3.up);
  Quaternion rotationToCenter = Quaternion.LookRotation(toCenter, Vector3.up);
  float angle = Quaternion.Angle(spawnFacing, rotationToCenter);
  
  Quaternion rotation = Quaternion.RotateTowards(spawnFacing, rotationToCenter, angle * normalizedDistance);
  spawnPoint = rotation * spawnPoint;
}

spawnPoint is a point in the unit circle that is converted to a vector3 the following way: spawnPoint = new Vector3(spawnPoint.x, 0, spawnPoint.y).normalized.
normalizedDistance is the player's distance from (0,0,0) divided by some number set in the inspector (in this case, 3).
toCenter is the direction to (0,0,0).

Should this not rotate the spawnPoint (which is a direction at this stage of the spawning mechanism) towards facing (0,0,0) based onnormalizedDistance? How do i do that?

[leaden solstice]

😄 https://schatzeder.medium.com/basic-trajectory-prediction-in-unity-8537b52e1b34

You can calculate base on initial force and gravity and all, but it does not put the obstacles in count, so that part you'd do shape cast or something.

[shy knoll]

thank you so much : )

[shell scarab]

To be clear, even when the result of angle * normalizedDistance is in the thousands, I am still getting points that are facing away from (0,0,0)

[leaden solstice]

I guess you want your object to look at origin point the more they are far from it?

[shell scarab]

I want my spawn point to be more towards the origin point the further they are away from it

[leaden solstice]

Hm, bit confusing, try log some values and see if they are correct for your intention?

[shell scarab]

im not sure what to log here besides the final value and the angle (which is how I know the angle is in the thousands). They're all quaternions and those won't mean anything to me.

[leaden solstice]

Actually

You are rotating spawnPoint again with LookRotation to the spawnPoint

I guess what you want is simply rotation * Vector3.forward or something

[shell scarab]

I tried doing Quaternion.Inverse(spawnFacing) * rotation * spawnPoint

actually wait I think I need to swap those two first ones

or possible Vector3.forward like you said

let me try

[leaden solstice]

Multiplication order is ever confusing

[shell scarab]

well left hand side is the start rotation right hand side is the rotation you're "adding" to it

[leaden solstice]

But not when you multiplying with vector

😄

[shell scarab]

well that you just make sure the quaternion is on the left

[leaden solstice]

Anyways your rotation already has the rotation for the spawnPoint included

So technically you'd just want unit vector to rotate alongside with it

[shell scarab]

multiplying the rotation with Vector3.forward gives the same result as rotation * Quaternion.Inverse(spawnFacing) * spawnPoint and it's really weird

[leaden solstice]

That's normal

[shell scarab]

it looks like it's working but in the wrong way lmao

[leaden solstice]

Because Quaternion.Inverse(spawnFacing) * spawnPoint should be just forward vector

[shell scarab]

maybe? Idk. It should be the rotational difference between the look rotation and the current rotation I think, which is not always a forward vector maybe?

[leaden solstice]

No spawnFacing you made was LookRotation to the spawnPoint

So "undoing" it should be just forward vector

[shell scarab]

ah

hold on I need to make a quick gizmo component to show you the result

its strange

my player is selected

here the angle is in the thousands since the normalized value is over 2

[shell scarab]

I'm doing this: for the last line in that if statement spawnPoint = (rotation * Vector3.forward).normalized;

[leaden solstice]

And what shows the spawnPoint here?

[shell scarab]

the yellow spheres, sorry

(0,0,0) is at the center of the green plane

[shell scarab]

What could be affecting it like this is that this code is in a loop, where if the position is invalid it increases the radius a bit and tries again. So that's why they're in lines like that. But why are they in lines like that? Each time it loops it does another random point.

without looping it looks like this:

they seem to always spawn to the right of the player, on the positive x axis

I see what I'm doing

hold on

I'm spawning the points around the player

i need to remove the player's rotation as well

[leaden solstice]

Like in local space?

🤔

[shell scarab]

yes, since this is all in world coordinates around (0,0,0), I treat that in local space and use transform.TransformPoint

yes works good now! Thanks for your help cathei!

[limpid agate]

hey guys, lets say I have a direction A and a cube

and I want to get the X degrees

how can I calculate it

the dotted line is the normal

[shell scarab]

in 3D space or 2D space?

[limpid agate]

3D space

to put it in even better perspective, let B be a point in space. I want to know how much to rotate the cube so that B will be the reflection of vector A on the surface on the cube

so given A and B coordinates, I want to rotate the cube much enough for B to be reflection of A

that's actually what I need

[naive summit]

Why doesnt my script call the second script?

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

public class FlashLightOnTable : MonoBehaviour
{
    Player player;
    void Awake()
    {
        player = GameObject.Find("Human").GetComponent<Player>();
    }

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

    public void OnMouseDown()
    {
        Destroy(gameObject);
        player.PickUpFlashlight();
    }

}

There are no errors in the console

[lean sail]

Can you clarify more what reflection you're trying to achieve? Because there is a reflect method you can use to calculate where a vector should point after reflecting on a surface (you pass in the surfaces normal)
But if you're rotating the cube, this now changes

[somber nacelle]

how have you confirmed it doesn't

[naive summit]

Because in the second script when PickUpFlashlight is called the player is supposed to hold the flashlight but that doesnt work. So i set an Debug.Log("Activated") In the second script to check if it's even being called but nothing shows up in the console either

[somber nacelle]

okay and have you confirmed that the code you've shown is actually running?

[naive summit]

Ye, the gameObject gets destroyed when i click on it

[somber nacelle]

then either you have an exception in the console that you are ignoring or PickUpFlashlight is being called.

oh the other possibility is that something else is destroying the object

[naive summit]

No, im just an idiot. I just noticed i put the second script in wrong GameObject bruh

But thanks for the suggestions lol

[somber nacelle]

second script in wrong GameObject
so then you did have an error in your console that you were ignoring

[naive summit]

No, there were still no errors in the console. The second script was supposed to be put in the Player, but istead of putting it in the Player i put it in the SpotLight which is also in the player which is supposed to be the flashlight itself

But there were no errors in the console

[somber nacelle]

unless your spotlight is also named Human then you absolutely had an error that you were ignoring

[naive summit]

Huh hows that

[somber nacelle]

you would have received a NullReferenceException when attempting to call the PickUpFlashlight method on the player variable

[naive summit]

Oh i did get that yes, but since there are some other errors in the console not related to that script i thought it was just another error that wasnt related. My bad

sorry im a bit new to coding in unity

[somber nacelle]

oh my god. if you literally have errors in the console then do not insist that you do not have errors in the console

[naive summit]

Okay

[errant flame]

Can anyone help about this problem or any idea 🫤
https://discussions.unity.com/t/graph-view-list-view-problems/363699

[rigid sleet]

use a raycast and use the hit.normal

oh wait I missread your drawing

I think for your case Quaternion.FromToRotation should be the solution, use your first direction with the normal, and that will give you the rotation between your vectors

then apply that rotation to your normal and you should end with your wanted direction

also, since this is a cube btw you can just flip your y direction

[broken bone]

Hey everyone, I saw a book recommended for beginners to C# quite a few times online, but, it was published Jan.2022, is there anything that would be incredibly different in that amount of time or mostly similar?

[calm talon]

there wouldn't be any significant changes, everything in there should still apply

[leaden solstice]

The basics are same, only additional features
You should look what version of C# is tho

Unity is bit late for adapting modern C# anyways

[broken bone]

It says C# 10 .Net 6 on the cover?

[leaden solstice]

That's good enough, Unity uses, eh, C# 9.0

[broken bone]

C#10 would still work with C#9 mostly, though?

Yeah most of it will work or easily converted

[frosty widget]

PLEASE does anyone know how drag works in unity and how it's calculated? It's been driving me CRAZY

[cosmic rain]

There are many ways to implement it. You'll need to share some more context and info on what exactly you've tried so far.

[frosty widget]

Here's the entire situation. I am trying to restrict the horizontal movement ofmy character by setting the character's velocity to a max speed. However, at the end of fixedupdate, this value is reduced by drag. I then decided to reduce drag to zero, which fixed that problem, but introduced another, because now my character jumps much higher than intended. Now I would like to apply drag to my character but only vertically, because I want both my jump height to be normal and for drag not to apply horizontally

Which is why I've tried to find some sort of formula for applying vertical drag manually

[cosmic rain]

Drag is basically reducing the velocity by some percentage(of flat amount?) every frame.

But I think it would be better to just adjust your jumping height/velocity, instead of introducing a drag for it.

[frosty widget]

well my problem is that I only bring drag to zero when I've reached max horizontal speed, so currently my character jumps much higher running than when its standing still

I could show a video of it if you would like

[cosmic rain]

Sound like some very unreliable logic. Maybe avoid modifying the drag at runtime and find some better solution

[frosty widget]

should I be using drag to decelerate the player?

that is currently how I'm using it

[cosmic rain]

Depends on what kind of controls you want. I'd say no.

[frosty widget]

I'm planning to have movement where the character doesn't stop and start moving immediately. I plan for the character to accelerate until reaching a max speed and decelerate until it stops moving

idk I kind of have a feeling like I shouldn't just be ditching drag, but it has been rather difficult to deal with

[cosmic rain]

Should be pretty easy if you use your input to controll the acceleration instead of velocity

The jumping can then control the velocity separately.

[frosty widget]

what do you mean by that?

[cosmic rain]

Exactly what I said. You should probably know from school that acceleration determines how velocity changes over time. And velocity determines how position is changing over time. By controlling acceleration you would be able to speed up and slow down over time.

[frosty widget]

I already do that from my script, I'm just having problems with setting a limit on the character's velocity

without drag affecting it

[cosmic rain]

You can limit it with a clamp or something similar

https://docs.unity3d.com/ScriptReference/Vector3.ClampMagnitude.html

[frosty widget]

also when does drag affect velocity? I have heard previously that drag apllies to the velocity only until after the body of fixedUpdate executes

[frosty widget]

thank you I think I will use this

[tawdry fox]

I've hit a catch 22 where in I have a separate deceleration value if a player is above the intended speed (I want them to accumulate speed) and that works fine for maintaining speed. The issue however arises that using that separate decel value makes it nearly impossible to turn. Is there a work around? Since the whole "acceleration is change of speed over time".

[cosmic rain]

Drag is applied in the physics update(which happens to be right after the fixed update) among other calculations.

[cosmic rain]

You'll need to share more info about your issue and it's context.

[cosmic rain]

Maybe record a video of what's happening first

[tawdry fox]

The dash deceleration is better at maintaining speed but because I'm still checking for input as part of this argument that means I maintain very little control.

aight

[cosmic rain]

Well, what kind of behavior do you want during a dash?

[tawdry fox]

Trying to record a good angle.

Car like turning with highly reduced deceleration. Additive speed game.

[cosmic rain]

Car like movement/steering is pretty complex actually. There are a lot of counteracting forces involved

[tawdry fox]

yeag

Couldn't get a good video example sadly.

[frosty widget]

then would it be a better idea to decelerate the player manually?

like, by using RB.addforce

[cosmic rain]

If you're setting velocity, I'd keep all the logic limited to setting the velocity

You could lerp(move towards or some other way) the velocity to 0 when there's no input

[frosty widget]

I see, thank you

[tawdry fox]

Any input on what I'm doing wrong here with the coyote timer? I feel like this makes sense but it isn't working out.

Should it be greater than?

[dusk apex]

Maybe you should explain what's happening and what isn't.

[tawdry fox]

Well I fixed it. It was greater than.

And it's a coyote timer. Doesn't really warrant as much explanation.

[spring creek]

We need to know what is actually happening....

We know what coyote timers are, that doesn't explain in what specific way yours wasn't working though

[tawdry fox]

I get that, but I'm not sure how I'm supposed to explain that the thing that doesn't eat a double-jump when leaving a ledge within a certain amount of time isn't working when I leave a ledge. It's commented and in the end was a minor syntax error.

"if in air but you didn't jump set the jump count to one higher unless you hit the timer"

[spring creek]

Well, you say the words you just wrote....
But at the same time you post the code

Because that is far from the only issue people have with coyote jump. For example, for some people they are able to do it after any amount of time

[tawdry fox]

Sometimes I just need an extra set of eyes. I'm sorry I really don't mean to come off wrong. I'll work on specifying issues going forward.

[gray mural]

Hello, is there any way to assign StartSomethingInternal to a value of type Coroutine and return it without using Unity's StartCoroutine etc.?

public void StartSomething(IEnumerator value) => StartSomethingInternal(value);

private async void StartSomethingInternal(IEnumerator value) => 
    await StartSomethingAsync(value).ConfigureAwait(false);

private async Task StartSomethingAsync(IEnumerator value) { ... }

[shell scarab]

Based on the snippet you provided, I don't know why you would want to have it return a coroutine. Why not just start a Coroutine in StartSomething?

Also you may want to look into the Awaitable class if your version of unity supports it if you're doing async stuff.

*I also don't know of a way, or I would have just told you

[gray mural]

That's because Unity doesn't provide Coroutines, which can run in the Editor. The context isn't really necessary, I just want to find a way to assign an async Task to a Coroutine

The reason why I don't simply use tasks is that I want to create an extension StartCoroutine method, which, in the Editor, runs according to my functionality, otherwise simply calls MonoBehaviour.StartCoroutine

[shell scarab]

well you should definitely look into the Awaitable class to see if your version of unity has it. Also, there's an editor coroutine package you can install! But, if you don't want to install any packages, I usually just make a new game object, attach some dummy monobehaviour to it, and use that as a "coroutine holder". I set the hide flags for the object so it doesn't appear in the hierarchy.

https://docs.unity3d.com/Manual/com.unity.editorcoroutines.html

[gray mural]

Editor coroutines don't work properly in the Editor, as WaitForSeconds cannot be calculated properly without Update, which in the Editor is called only when any changes are made

So Editor Coroutines package doesn't really fix anything

[shell scarab]

the editor coroutine package provides an "EditorWaitForSeconds" class which waits seconds in the editor using unscaled time

[gray mural]

I have installed this package already, but now I forgot whether I have tried to use EditorWaitForSeconds...

[maiden heath]

[field: SerializeField]
what is the "field" thing in the code block above? why put it?

[shell scarab]

it applies all the attributes in the []s to the auto-implemented field of a property

without the field keyword there it would try to apply it to the Property

[maiden heath]

what is this "property"?

[shell scarab]

A property is a way to encapsulate your data. It's sort of like a method. They're usually used to expose fields that you want read outside of the class but not written to. This is an auto-implemented property:

public string Name { get; set; }
```You can also implement them yourself:
```cs
public string Name
{
  get
  {
    return _name;  
  }
  set
  {
    _name = value;
  }
}
private string _name;
```Like I mentioned above, they're useful for data encapsulation. For example, maybe we don't want the name of this object to be changable by outside classes, only itself. We could do this:
```cs
public string Name
{
  get
  {
    return _name;
  }
}
private string _name;
```Which only has a `get` as you can see. OR we could do:
```cs
public string Name { get; private set; }
``` Which, as you can see, has an access modifier on the `set`.

[maiden heath]

ohhhhhhhhh i see now

thank you for the explanation

[gray mural]

So I've tried out EditorCoroutines package, it then took a while to be able to use its namespace, and was confused why this does work properly, as you can see in the image above, when simply starting a Coroutine.

private IEnumerator MyCoroutine()
{
    print("<color=blue>MyCoroutine start</color>");

    for (int i = 0; i < 10; i++)
    {
        yield return new EditorWaitForSeconds(1f);

        print($"MyCoroutine - i: {i};");
    }

    print("<color=blue>MyCoroutine end</color>");
}

I had a look on the EditorCoroutineUtility class and it seems like it does have its own method. Using it works properly in the Editor, which makes me a bit upset I have been trying to implement my own solution for a while.

EditorCoroutineUtility.StartCoroutine(MyCoroutine(), this);

Thank you for your help. You have saved my time I would've wasted 🙂

Im having a problem where i have a impct particle effect for where my gun shoots but when i move backwards the particle just attaches to my camera. can anyone help me out?

[cosmic rain]

You'll need to provide more info if you need help.

[inland lance]

what info would you need?

[cosmic rain]

Everything. Your initial message doesn't explain anything.

If it's hard to explain in words, record a video.

[inland lance]

alr give me a minute

[cosmic rain]

• What exactly is the issue? What do you expect to happen, vs what's happening.
• Share the relevant code.
• Describe the steps you took to debug the issue and what you figured out from them.

[inland lance]

that is my issue

[cosmic rain]

Mp4 please.

[inland lance]

alr

the code for the gun is

    }
}

}

public class SoundClip
{
internal AudioClip shootSound;

i followed a tutorial since im fairly new to programnig and having touble finding whats wrong with it

[inland lance]

done

[cosmic rain]

So, what happens actually? To me it looks like you hit your own character.

[inland lance]

yes thats the issue

i tried removnig the collision from mthe capsulle but it didnt change anyhting

[cosmic rain]

You could use a layermask in your raycast to ignore the collider of the character.

[inland lance]

give me a second to try that thank you

[inland lance]

sorry but where would i do that?

again im fairly new to coding haha

this is my first project

[cosmic rain]

Check the documentation for raycasts. The method can take a layermask as a parameter. There should be examples too.

[inland lance]

where is tht

[stoic ledge]

Are editor console entries cached anywhere?
Due to automatic "Clear on Recompile" I accidentally lost a very important log, that could help me fix an error.

[cosmic rain]

Google "unity API raycast"

[light pond]

So i have different tile images but i want to copy them or from the editor for other directions

how do i do that

but you get what i mean right

[inland bison]

Hello there !
I'm working on little thing, the idea is just to get audio files from player's folder (documents/My Games/gamename/radio) to load them into the game.
I can't use coroutine so I used async operation to do that, in this code everything working well but I'm just asking how I can change it to avoid the use of the while statement 'cause when it enter in this loop all the game stop and waiting for the loop to finish

[gray mural]

Select the asset and either drag it to the desired destination if you want to change its direction, or copy it by pressing Ctrl + C, selecting the desired destination and pressing Ctrl + V.
If you want to select multiple assets,

• Click on the every single asset with Ctrl held, or
• Click on the first and last assets with Shift held

[light pond]

how do i change direction

[gray mural]

Have you read my message?

[light pond]

like for example the second tile i want to make it face a different direction

[gray mural]

Oh, direction

For some reason I have read it as "destionation"

[light pond]

its ok

[gray mural]

I don't think you can do it directly in Unity. Simply do it in your own sprite editor and consider resizing the canvas to then slice them with the Multiple sprite mode for convenience

[light pond]

ok i guess i can do that

but unity should add this

[gray mural]

I can't use coroutine so I used async
You can indeed use a Coroutine, have a look on the method you're using.

yield return www.SendWebRequest();

[gray mural]

Unity has an option to flip an image in the SpriteRenderer

[queen mantle]

can you make a code for vr crafting

[gray mural]

Both vertically and horizontally

[light pond]

yo i can maybe try this

thanks

[gray mural]

Note that this doesn't change the original sprite

[gray mural]

This isn't UnityGPT

[queen mantle]

oh haha

[inland bison]

No I can't use coroutine x) my class doesn't heritate from Monobehaviour

[light pond]

ok thats good

[gray mural]

You can start a Coroutine on some kind of a Singleton, which doesn't get destroyed

Or on any other MonoBehaviour reference

[inland bison]

I just can't 'cause of my script system but I found a solution, I just removed the while loop and just await Task.Yield(); and it works fine so yep... I don't know if it's a good use

[simple egret]

Dangerous, the request might not have finished after a single yield

Depends on the computer and IO speed

[gray mural]

await Task.Run(() => www.SendWebRequest());

[inland bison]

yeah that's what I supposed

[inland bison]

ow that's seem good

ouch

[gray mural]

What about this?

await Task.Run(() => www.SendWebRequest()).ConfigureAwait(false);

[inland bison]

same

[gray mural]

Does your initial code give the same error?

[inland bison]

nope

the initial code that I sent was perfectly fine, no error

[gray mural]

Then you just cannot await the web request

Consider either using your initial code or the coroutines then

[inland bison]

there is no possibility to just change the initial while loop ?

[gray mural]

I don't think so

Probably, just by creating your own method

[simple egret]

Have you tried with delaying the task? await Task.Delay(delayMilliseconds)

[gray mural]

#archived-code-general message

Oh, this is not what you mean

[simple egret]

The best way would be to use a combination of TaskCompletionSource and subscribing to the request's completed event

[inland bison]

ok I have a code that's working but ^^' it's very very very bad x)

[gray mural]

for (int i = 0; i < i++;)

What about this one?

I feel like it should compile

Although start from -1

for (int i = -1; i < i++;)

[inland bison]

this will loop forever no ?

[gray mural]

Sure

Oh, have just read your code

I thought you just wanted to print i

Why can't you do it in a while loop?

[inland bison]

'cause I don't really know why but in unity when you enter in while loop all the game is paused while you're in the loop

[simple egret]

It would look something like this:

TaskCompletionSource<AudioClip> tcs = new();

using UnityWebRequest www = ...
www.completed += () =>
{
    // get clip
    tcs.SetResult(clip);
}

www.SendRequest();
return tcs.Task;

[inland bison]

I don't ever worked with that thing, I will try

[simple egret]

Oops the completed event is on the operation, not the request, so you need to send it then subscribe on that. But the structure is roughly the same

[inland bison]

ooooooooook I'm missing a thing ^^'

[simple egret]

See above

[inland bison]

yep but like I said I'm not familiar with this system (I have to learn it, it seem very usefull)

[simple egret]

The completed event is on the operation variable, not on www

[inland bison]

oooooow ok my bad

something like that ?

[simple egret]

var operation = www.SendWebRequest();
operation.completed += operation => {
    
}

[inland bison]

ok

[simple egret]

Yep, it passes the operation itself in the lambda argument, so you can't use a empty parameter list () =>

[inland bison]

oooook it seem good and what it's returning exactly ?

[simple egret]

Well, you need to move the old code that downloads the clip inside that lambda first

The DownloadHandlerAudioClip.GetContent() one

[inland bison]

ok that's good

[simple egret]

And then change your method so it's an async Task<AudioClip>

[inland bison]

ooooooook

argh

[simple egret]

And you should be able to do AudioClip clip = await xyz.LoadAudioClip("path", type)

Oh don't mark it async my bad

[inland bison]

oh or can I just write return tcs.Task.Result;

[simple egret]

Or you return await tcs.Task and leave the method async, your choice

[simple egret]

No don't, this blocks the thread waiting for the task to complete, eliminating all usefulness of async

[inland bison]

oh ok

go testing

oh ok no

that's my fault

I've just passed wrong param

yeah it works !

thanks bro !

Just what this system is called for that I search on internet to learn it ?

[simple egret]

C# TaskCompletionSource will get you most results

[inland bison]

ok thanks !

[olive harness]

why do I get the error "SetDestination" can only be called on an active agent that has been placed on a NavMesh. when It's clearly on the navmesh ? is there a fix to this ?

[leaden ice]

Read the stack trace of the error to find the offending line of code. You are probably calling SetDestination on a prefab or something

[olive harness]

nope, I'm calling it inside a component that has a reference to the navmeshagent

[leaden ice]

Yeah but which navmeshagent

it's likely a reference to the wrong one

[olive harness]

there is only one

[leaden ice]

SHow us

show us what the code is referencing, and how you got/assigned that reference

[olive harness]

there ya go

class is EnemyNavigator

[leaden ice]

can you scroll all the way up to the top of the console window?

[simple egret]

Basically in the old days where async/await wasn't broadly implemented, most of the code base used something like Unity uses today, where you had BeginXYZ() and EndXYZ() methods that were to be called to start/stop the "async" coperation, along with an event to signal when the operation was completed.
When async/await was introduced, a whole bunch of types like Task were introduced for the new methods, but the old ones still existed. To bridge both worlds while Microsoft switched to the async/await pattern, devs used that TaskCompletionSource class to "convert" the Begin/End pattern into methods that could be used with async/await.

[olive harness]

Exactly, you can see in the first photo it is clearly right on top of the navmesh

[leaden ice]

Actually I can't, because you have this set to Center
It should be set to Pivot to know where the object actually is.

[inland bison]

ok I see, very interesting

[olive harness]

pivot is at right at the enemy's hands (they are touching the ground) and in the picture you can %100 see that the agent is touching navmesh

@leaden ice

sorry for tag forgot to reply

and with pivot selected :

[leaden ice]

I'm not an expert on NavMeshAgent exactly so I'm not sure of the intricacies of what might be going wrong here

This might help https://forum.unity.com/threads/failed-to-create-agent-because-it-is-not-close-enough-to-the-navmesh.125593/

Also are you generating the NavMesh at runtime @olive harness ?

[olive harness]

no, it's generated beforehand

weird, I'll update unity maybe it'll fix it

[swift falcon]

can i learn c# while learning unity c#? like, would i learn c# while making platformer without knowing c#? (i wish)

[leaden ice]

I think it's better to know C# beforehand, but yes you can learn both at once. Many people do.

[swift falcon]

yaaayyy

[knotty sun]

don't rejoice too much, trying to code in Unity without knowing at least the basics of C# will make your life so much more painful

[swift falcon]

i think i know very basics

thanks anyway

[heady iris]

If you have moderate programming experience, you can pick them up together.

[swift falcon]

im not moderator 😰

oh, moderate

[sterile reef]

I did, but eventually did an IT study for mainly c#.
So it's still wise to learn c# outside of unity

[knotty sun]

very sensible. A good grounding in C# will make your learning experience in Unity so much easier

[sterile reef]

My very first interaction with c# was a tower defence tutorial from Brackeys.

The problem with focusing on unity alone is that a lot of tutorials won't teach you helpful and sometimes important aspects of C#

For example: Extention methods

[knotty sun]

this is a common falacy. Tutorials don't 'teach' shit. They show one way of doing one specific thing. Nothing more

[sterile reef]

They help (me) understand the functionality of a certain aspect.
If I were looking into animations, I search up multiple tutorials to show me how I could implement stuff and based of the info I experiment

And end up in more stackoverflow pages

[knotty sun]

then you are taking the right approach. Most people copy verbatim and understand nothing

[heady iris]

video tutorials where you just copy down code from the screen could be replaced with a .unitypackage

[sterile reef]

😼

[knotty sun]

that is what passes for 'learning' nowadays. No actually brain or thought required

[heady iris]

i've been thinking about creating a tutorial series that's more concept-oriented: e.g. a video or article that explains the concept of GameObjects and Components

unfortunately that does not instantly give you a working game

and i can't put "IN JUST FIVE MINUTES" in the title

[knotty sun]

yeah, no 'quick fix', no audience

[heady iris]

on the other hand, it would be significantly more useful for people who are actually interested in learning

[inland lance]

how do you make diffrent particle for a gun by hitting diffrent layers?

[heady iris]

so sparks when you shoot a metallic surface, dust puffs when you shoot dirt, etc.?

this is going to be very similar to making footstep sounds for different surfaces

[leaden ice]

Make a script like:

public class Surface : MonoBehaviour {
  [SerializeField] ParticleSystem bulletImpactPrefab;

  public void Hit(Vector3 position, Quaternion orientation) {
    Instantiate(bulletImpactPrefab, position, rotation);
  }
}```
And assign it to each surface

And in your shooting code, grab this component from what you hit and call Hit on it

[inland lance]

ok thank you!

[leaden ice]

Another option is to use tags

[sterile reef]

Why do this on each surface?

[leaden ice]

so you can configure the impact behavior on each surface as desired

[heady iris]

The first thing I thought of was to make a mapping of Material -> ParticleSystem that you store on the weapon

But this has a few problems...

RaycastHit can't tell you which sub-mesh you hit (mesh colliders have no concept of this, or of materials in general)

you could look for a mesh renderer on the thing you hit and ask it for its main material

but since materials get instantiated when you access .material, you'd have to access .sharedMaterial instead

[leaden ice]

To be clear there are many different ways to do it

[sterile reef]

If I were to do something I'd make a scriptable object that stores a dictionary<int (layer), gameobject> and when hitting a gameobject it would compare and spawn based on the layer

[heady iris]

I like this idea the most.

[plucky inlet]

I would use a simple script that just holds the enum of your ground type. In your raycast just check for that element and according to the enum, spawn / play the desired particle system.

[heady iris]

It avoids tying your impact effects to other weird stuff.

[leaden ice]

It could be a problem if there's a huge number of objects in the scene and/or if you need different submeshes of objects to have different impacts like you were saying

but yeah

it's modular

[heady iris]

I'm not a fan of using layers, because that means you're eating up a lot of layers just for impact effects

[leaden ice]

oh certainly

[heady iris]

you want to use layers for conceptually different things

[leaden solstice]

Think you can do approach similar to "physics material"

Differnt sound, impact particle, etc

[leaden ice]

Yep exactly

[heady iris]

I'm having trouble expressing this, but you have to watch out for..."invalid relationships"?

Situations where it looks like X and Y go together, but then it later turns out that they don't

they just happened to fit together in most cases

[leaden solstice]

XY problem? 🤔

[heady iris]

like, not every object with "Metal" in its name should make a spark when you shoot it, so using the object's names would be bad

nah, I just picked X and Y as two random variables

[heady iris]

(and some objects not named "Metal" would also need sparks)

and looking for the material on the object you hit would be problematic

you might have colliders on child objects that have no renderer

[sterile reef]

I mean.... with your component approach you can just make a script what pools the objects with the same scripts right?

[leaden solstice]

Usually: make designer assign correct one 😄

[heady iris]

i'm not sure what you mean here

[leaden solstice]

Not my fault ™️

[heady iris]

if you mean pooling the particle systems, then yeah

[sterile reef]

Yeah

[swift falcon]

is it possible to take the unity standard human rig and seperate it to make a rigidbody based movement system?
i tried playing around with it but I have no idea what im doing
or is there a humanoid that comes unrigged

[leaden ice]

Rigging is about animation

nothing to do with character movement systems

[swift falcon]

yeah I meant i want one without builtin animations, just the individual parts

[leaden ice]

You want one what

[swift falcon]

a person/humanoid

[dusk apex]

Check the Unity asset store for a free model

[leaden ice]

But what do you mean by "standard human rig and seperate it to make a rigidbody based movement system"

You mean instead of a single deforming skinned mesh, you want a bunch of separate object meshes for individual body parts?

What's your goal

[swift falcon]

I think so

[leaden ice]

For what reason

[swift falcon]

to make a custom movement system for fun

[leaden ice]

Is it because you can't figure out how to use a normal animated skinned mesh?

[heady iris]

this is ill-defined

[swift falcon]

sorry

[leaden ice]

I'm trying to figure out the link between "custom movement system" and the mesh

Normally these are completely unrelated

or mostly unrelated at least.

[heady iris]

Are you talking about making something QWOP-ish, where you move a character by moving their individual limbs?

[leaden ice]

You can do that with a normal skinned mesh^

Just don't attach an animator to it.

[heady iris]

If so, this has nothing to do with rigging. You're just moving the armature with physics instead of an animator

[swift falcon]

ok thanks everyone 🙂

[heady iris]

Is there a way I can decompose a Quaternion into rotations around a set of axes? Imagine turning one Quaternion into three sets of angle-axis values (where I provide the axes).

I am writing code to rotate a character's eyes. I want to limit the amount of rotation around the left-right and up-down axes. In the image above, I'd want to limit rotation the red and green axes.

It's not so simple as just limiting the local euler angles, since rotating around one of these axes winds up changing all three of the eye's X/Y/Z local euler angles! I am also not a fan of messing with Euler angles in general, anyways.

I've wanted to do this kind of thing in many other situations, so even if I find another way to handle this, I'm still interested.

I was thinking of using the quatertnion to rotate a vector and then using FromToRotation to figure out some rotations, but this is going to lose the roll

[wary coyote]

    public void RotateObjectToFaceAway(Transform obj, Vector2 position)
    {
        float outerAngle = position.x * 2f * Mathf.PI;
        float innerAngle = position.y * 2f * Mathf.PI;

        float outerRadius = torusRadii.x;
        float innerRadius = torusRadii.y;

        Vector3 outerRingPosition = new Vector3(Mathf.Cos(outerAngle) * outerRadius, 0f, Mathf.Sin(outerAngle) * outerRadius);
        Vector3 innerRingOffset = new Vector3(Mathf.Cos(innerAngle) * innerRadius, Mathf.Sin(innerAngle) * innerRadius, 0f);

        Quaternion torusRotation = Quaternion.Euler(0f, -outerAngle * Mathf.Rad2Deg, 0f);
        Vector3 finalPosition = outerRingPosition + torusRotation * innerRingOffset;

        obj.localPosition = finalPosition;

        Vector3 direction = (outerRingPosition - finalPosition).normalized;
        Quaternion lookRotation = Quaternion.LookRotation(direction, Vector3.up);

        obj.localRotation = lookRotation;
    }```
I am trying to position meshes equally spaced on the surface of a torus, with rotation orientation on the XZ to be up away from the torus and rotated around the ring O inner part.
I have it 99% of the way there but for some reason the cubes at the highest point and lowest in the Y axis alone don't get the correct rotation vector (as shown selected in orange).
Can you see why this is occuring? I haven't been able to debug the cause, I am assuming the issue has something to do with Vec3.Up that its not able to orient correctly because the direction is perfectly straight up/straight down?

[heady iris]

yeah, if you use LookRotation where the direction and up-vector are identical, you won't get good rolls

[wary coyote]

What would you suggest in place of lookRotation?

[heady iris]

I think you still want LookRotation, but with different inputs

[wary coyote]

I can do something other than it if for sure

[heady iris]

adding some Debug.DrawRay calls will help visualize what's going on

it looks like direction points from the center of the toroid ring to the position of the cube. Is that right?

[wary coyote]

I think so? It's tough for me to verbally describe a torus because its all circumferences, when I say 'ring' or 'center' its ambiguous if I'm talking about the Macaroni center (purp) or planetary center (yellow)

[heady iris]

My first thought is to replace Vector3.up with one of the toroid's tangent vectors. It'd be the tangent that walks around the ring like this

i also need to figure out the vocabulary...

for a cube on top of the torus, you'd get these vectors

it would look in the direction of the long vector with the short vector as the "up" vector

You should be able to compute this with...

actually, I need to think on that for a sec

you'd be rotating the direction vector around the camera axis here

by 90 degrees

You're looking for the direction the disc is going

[wary coyote]

        Vector3 tangentVector = torusRotation * new Vector3(-Mathf.Sin(innerAngle), Mathf.Cos(innerAngle), 0f);
        Vector3 direction = (outerRingPosition - finalPosition).normalized;
        Quaternion lookRotation = Quaternion.LookRotation(direction, tangentVector);

[wary coyote]

You nailed it already, this was it

[heady iris]

Which you can compute much like the actual position -- it's just a phase shift of 90 degrees

nice!

By getting rid of all of world-space vectors, you wind up with something that works at any orientation

[wary coyote]

Looks good and works good (adjusting the torus diameters and circumferences)

[heady iris]

i've been trying to clean this kind of thing up in my game, so that when I start doing weird stuff, my old code doesn't break

assuming that world-up is always your up works until it doesn't (:

[wary coyote]

Yeah 🫠

[heady iris]

actually getting that tangent can be a major problem for more complex situations

[wary coyote]

I am going to animate this later on, trying to build up towards something like, so likely I'll be back when that blows up positioning and rotationing is step 1, next is moving it

[heady iris]

You might want to write a function to calculate a set of basis vectors for any point on the torus

you'd have:

• normal
• outward tangent
• circular tangent

(you already have two; just cross-product them to get the third one)

i may have drawn the third vector backwards

this is just another coordinate space, much like world-space or local-space

[wary coyote]

Ooh okay yeah that makes sense. Ill refactor my direction codes out of the rotation method into standalones that can be called

[heady iris]

it's way easier to reason about problems when you're in the right space

[wary coyote]

torus-space

[heady iris]

you can either compute world-space vectors for each of these things

or you can figure out how to convert back and forth between world-space and torus-space

[wary coyote]

actually this just made me remember:
A 2D map that loops NS and EW is a torus 🤔

[heady iris]

the latter would be nice: [1,0,0] would be a normal vector when converted back into world space

I am a little murky on how you do that -- it's a https://en.wikipedia.org/wiki/Change_of_basis

If you have three vectors and an origin, you should be able to bash together a transform matrix..

Ah, you could use Quaternion.LookRotation to create a rotation out of two of the vectors, then combine that with the position with Matrix4x4.TRS (it takes a position, rotation, and scale) https://docs.unity3d.com/ScriptReference/Matrix4x4.TRS.html

I should try that out

Once you have a Matrix4x4, you can use it to transform to and from torus-space

basically anything you can do with a Transform

[wary coyote]

Ill have to think deeply on this. I am good with logic but algebra, math transformations are my weak point

[ionic tusk]

How can I get the 2º and 3º class variables show on inspector?

[heady iris]

I don't see a TriggerColliderScript anywhere in the second screenshot

[leaden ice]

Yeah looks like you have two different classes defined in this file?

three of them actually

[ionic tusk]

yup exatly

[leaden ice]

well - why did you do that

Each script needs its own file

and he one shown is not the one you attached to the object

[ionic tusk]

one for each triggerCollider! I need logic for each triggerCollider

[leaden ice]

you really don't

but that's a separte topic

the main issue here is you can't have multiple MonoBehaviours in one file

and code you wrote in one class has no bearing on the other class

[ionic tusk]

ok... So how can I have different triggersColliders in one script?

[leaden ice]

You have a CS_Baliza attached to the object. The code in TriggerCollider1Script doesn't affect CS_Baliza

[heady iris]

you don't define more than one MonoBehaviour class per script file

[leaden ice]

I don't understand what you mean by that reallky

[ionic tusk]

yes I know

[leaden ice]

what are you trying to do?

[heady iris]

and adding something to one class doesn't make it show up in another

[leaden ice]

THis is the wrong way to do whatever you're trying to do.

[leaden ice]

I gues you're saying you have multiple colliders on this object and you want each one to do something different when it triggers with another collider?
YOu would do this:

• Move the colliders onto child objects
• Attach a script to each child object to handle their OnTriggerEnter behavior.

And when you write multiple scripts you have to put them in different files.

[ionic tusk]

so what I need is:
I am making a "checkpoint" like for a racing game, and the vehicle has to enter in the right direction on the "balizas" so my idea was: Use a triggerCOllider to check if it can trigger the second and check the checkpoint

[ionic tusk]

the colliders already are on different child g.o.

[leaden ice]

then put the separate new scripts on each child object

[ionic tusk]

I just didnt want to have 2 scripts...

[leaden ice]

but you already did. in fact you wrote three

[stuck hollow]

Can someone help me with this ?

[ionic tusk]

yes i guess...

[heady iris]

did you read the error message

[leaden ice]

Look at the full stack trace of the error and go to the offending code and fix it

[stuck hollow]

i didn't touch any script i was doing my gui

[heady iris]

it explains the problem

[knotty sun]

show the stack trace

[heady iris]

ah, see the stack trace then

[ionic tusk]

your index is bigger than the list size.
or negative

[knotty sun]

you are just guessing

[stuck hollow]

how can i fix that ? i didn't code anything i just added a ui images and text (also i'm a beginner i don't know much about unity)

[ionic tusk]

nop I just fix the same exat code msg on my project
EDIT: I think i awnser wrong statement XD

[heady iris]

you have not shown us the stack trace. please show us the stack trace

it appears below the error in the console when you have it selected

[leaden solstice]

Tell that to someone that coded it

[knotty sun]

yes you are, you have no idea if this is even caused by one of his objects

[knotty sun]

show the stack trace like you have been asked to, twice

[stuck hollow]

what is stack trace ??

[gray mural]

No other way to answer it, unless the op provides more information

[gray mural]

Click on one of these error messages

And paste it here

[knotty sun]

it's the bit at the bottom of the console when you select an error

[gray mural]

The stack trace shows the full way to your error

[stuck hollow]

this ?

[knotty sun]

yes, Unity bug, restart your editor

[heady iris]

looks like the renderer threw up. that's not your problem

as a rule of thumb: if you don't recognize anything in that stack trace, it was a problem on Unity's side

[stuck hollow]

oh ok thx guys

it works now

[stable lintel]

can i add a disabled component to the object

or add and then disable, before component calls Start()

[knotty sun]

yes, although Awake will be called

[late lion]

Start is called just before the first Update is invoked, so you should be fine with adding and disabling.

[stable lintel]

don't care about awake

[stable lintel]

should i? can it be that disabling happened after start, like cuz system lagged?

[heady iris]

no, things run in an exact order

your code can't "delay"

[deft pebble]

Hey, I'm trying to create an atlas v2 through script. Basically what I'm doing is:

var atlas = new SpriteAtlas();
atlas.Add(spritesArray);
AssetDatabase.CreateAsset(atlas, "Assets/SomeName.spriteatlasv2");

But doing so causes a native error to appear saying that this extension is not supported. Removing v2 from extension lets me create atlas, but it's a v1 one. I've searched everywhere, but couldn't find a way to create v2 atlas through code, any ideas?

[stable lintel]

well, maybe some async shit going on

[heady iris]

why do you think this is happening?

[stable lintel]

just curious

[heady iris]

so you aren't actually having a problem

[stable lintel]

im testing a thing out rn

[deft pebble]

If "system lags" then the whole unity event cycle stops. There's a clear order in which everything happens, event async operations
https://docs.unity3d.com/Manual/ExecutionOrder.html

[heady iris]

You'd have to be genuinely running things on multiple threads to get this sort of thing

and other threads aren't permitted to touch most of unity's data

[stable lintel]

well, everything works

trying to measure if runtime terrain spawning + grass zone spawning causes lag spikes

and well, it certainly does

well, terrain mesh instantiation doesn't actually consume much fps

var results = new NativeArray<RaycastHit>(totalCount, Allocator.TempJob);
var commands = new NativeArray<RaycastCommand>(totalCount, Allocator.TempJob);
for (int i = 0; i < totalCount; i++)
{
    commands[i] = new RaycastCommand(RandomPoint(), Vector3.down, QueryParameters.Default, transform.localScale.y + 0.02f);
}
JobHandle handle = RaycastCommand.ScheduleBatch(commands, results, 1, 1, default);
handle.Complete();```

alr i found my fps eater

[heady iris]

this is one place where you can kick things onto another thread for a bit (:

note that the game will stall the next time it tries to update physics if a raycast command is running, iirc

[stable lintel]

can i somehow prohibit object from updating unless jobhandle is complete

[heady iris]

I use raycast commands to batch up a bunch of work for my game's vision system

[fallow quartz]

Is there a way to deactivate collision forces push between to dynamic bodies but still having the oncollisionenter proc? Or making a collider trigger but still standing and not falling off the ground?

[heady iris]

that's what happens. the game freezes until handle.Complete() returns

[stable lintel]

so well, can i freeze the object and make it wait until thread with handle is completed

not the entire game

but just the object

[heady iris]

in 2D, yes, you have forceSendLayers and forceReceiveLayers in the newer versions of Unity. I don't think 3D has such a thing

[heady iris]

you could check if the job handle is done and skip the rest of Update if it's not finished, I guess

[stable lintel]

the entire update in my case

[heady iris]

you'd want to get rid of handle.Complete() (and store a reference to the JobHandle in a field so you can check it later)

[stable lintel]

well, i call this method single time per object

i'd prefer some way to deactivate object or component until thing is done, but disabled stuff doesn't call update anymore

i don't even need the component until job is done

[fallow quartz]

doesnt exist? im in a really new version btw

[heady iris]

checking handle.IsCompleted at the top of Update and returning early if you get a false is roughly equivalent to disabling the component

[heady iris]

It's an instance property, not a static property

it won't show up like that

https://docs.unity3d.com/ScriptReference/Collider2D.html

[stable lintel]

get the component from object and search there

[heady iris]

you need a Collider2D variable

[fallow quartz]

is there any place to check the different parameters i can send to the method or how does it works?

https://docs.unity3d.com/ScriptReference/Collider2D-forceSendLayers.html

here they dont show up

[somber nacelle]

it's a LayerMask property, not a method

[stable lintel]

can i dispose commands array before job is finished

[heady iris]

No, because then you'd be throwing out the data the job is working with

You have to keep those around and then dispose them when the job is done

[stable lintel]

feels bad sadly

i need to keep the job reference, the command and results arrays, as well as some other stuff

on each component

and also for each component do if checks each update

while components amount might get to like 1000

idk if it's gonna affect fps

[fallow quartz]

Okay and how can I avoid duplicating Code? I have some variables and methods repeating in some enemies, but then I have other variables and other methods repeating in other enemies and the player, so I cant use inheritance because that would make a huge tree. Interfaces also are not an option cause they still force me to duplicate code

[stable lintel]

wdym you can't use inheritance

enemies and player are surely inheriting some kind of "LivingEntity" class/interface

[heady iris]

you're looking for composition

instead of making a bunch of classes like EnemyYouCanShoot and EnemyYouCanShootWhoCanFly, you make simpler components

for example, an enemy's locomotion -- how it moves around -- should be separate from the logic for making it explode when it reaches 0 HP

[fallow quartz]

So I make a class, instantiate inside the player and just take whatever I need?

[fallow quartz]

Dependency injection would not be a good option?

[sterile reef]

You can have multiple components on 1 object

And multiple of the same type

[heady iris]

dependency injection is a separate topic

here, have a look at one of my entities

[void wedge]

Would u make a class containing everything the enemies / player would have in common then fill in the rest in their own file? Then in their custom file u can call on this class with its peramaters, sprite, move speed, health, etc.. then add in the custom variables and functions for that specific enemy?

[heady iris]

i should have split this into several game objects

this is an entity I use for benchmarking my vision system

the Entity component glues all of the other components together

it has an Empty Brain component that does nothing and an Empty Locomotion component that also does nothing. These could be replaced by more complex components to let the entity make decisions and move around

It has a Vision component that lets it see, and a Visible component that lets it be seen

I didn't have to create a new VisionBenchmarkEntity component to make this work

[heady iris]

assigning references in the inspector is a form of DI, so you're already doing it (:

[sterile reef]

Interfaces are a form of dependency injection

And I love using interfaces

[sterile reef]

Are these built in unity stuff or did you make custom icons

[heady iris]

The icons are mine

I made them in blender!

[sterile reef]

Nice!!

... make them in blender?

I like the dedication

[heady iris]

i know it better than Illustrator lol

[heady iris]

the icons are meant to represent how an Entity contains Modules

Modules are pretty much just ordinary components, but the Entity calls Update/LateUpdate/etc.-esque methods on them manually so that I can better control the order of execution

and I can ask the Entity for Modules instead of having to do a GetComponentsInChildren call

[sterile reef]

Does the main entity subscribe to the components or do the components subscribe to the main entity

I got my answer

[rigid island]

Interfaces are cool. Not sure I'd call them a form of DI though

[somber nacelle]

interfaces on their own are not a form of dependency injection, however many DI frameworks typically expect you to inject interfaces

[rigid island]

yeah that is true , most notably the asp.net one

[sterile reef]

Yeah true

Part of DI

[rigid island]

much cleaner with interface so you can switch up the implementations

[sterile reef]

I spread mischievous partial misinformation

[rigid island]

the "Brackys" route

[sterile reef]

Do you really need DI tho ?

[somber nacelle]

it really seems like you are confusing the concept of dependency injection with DI frameworks. you can do DI without some bloated framework

for example, assigning references in the inspector is a form of DI

[sterile reef]

I guess

[rigid island]

you don't need to ever do "DI" or SOLID is just helps keeps stuff clean

[somber nacelle]

literally just passing an object to a method or an object ctor is DI

[fallow quartz]

if i use composition and i declare for example the class into the other class in the inspector the variables from the class that is getting declared in the other one will appear?

And also, I cant figure out how to use forcesendlayers

[heady iris]

I can't really parse this question

If you do this...

[somber nacelle]

wdym how to use it? it's a property that you assign a LayerMask to

[heady iris]

public class Foo : MonoBehaviour {
  public Bar myBar;
}

public class Bar : MonoBehaviour {
  public int stuff;
}

then you'll get a "My Bar" field in Foo's inspector

[rigid island]

an interestingly now the recent .net frameworks for DI use the "Singleton" extension method

[heady iris]

you can drag a Bar into it

[heady iris]

as i somewhat-sarcastically say, 2 + 2 is DI

i injected 2 and 2 into the operator function

[sterile reef]

Both mono?

[heady iris]

these are both components

hence I am deriving from MonoBehaviour for both

[fallow quartz]

and how do i assign it?

[somber nacelle]

=

[heady iris]

are you asking how to set up the layer mask in the inspector?

[rigid island]

you wouldnt be able to assign in inspector otherwise

[sterile reef]

I've used [serialized]

[leaden solstice]

That’s fine since it is singleton in that specific context, not static for program lifetime

[sterile reef]

And it works

[heady iris]

If Bar is a plain-old class and not a MonoBehaviour, and you mark it as [System.Serializable], then it will appear in Foo's inspector

[sterile reef]

I serialized the class and can assign in inspector

[heady iris]

And since it's not a unity object, you'll see its values directly there

rather than needing to assign a reference to a Bar somewhere else in the scene

[fallow quartz]

no, just how to make the collision of an enemy only apply the oncollisionenter code and not the force, because if the force is applied after dashing and im inside the collider i will go down the floor

[rigid island]

isnt that the Lifetime of the program? interesting one is the "Scoped" as it scopes within the session rather than program lifetime
Maybe I'm just too used to working with aspnet recently 🤕

[fallow quartz]

and you said i need to use the forcesendlayer for that

[heady iris]

are you even using 2D physics here

we should start with that

[leaden solstice]

If you have multiple server or test running, there would be multiple of those 'singleton's

[heady iris]

behold: the multi-singleton

[rigid island]

oh multiple. I mean 1 server app

[heady iris]

singleton't

[fallow quartz]

yeah, i have a boss which is like x3 size of my player. The boss has a dynamic body, same as my player, so when i dash into him (which the dash ignores collision with all enemies until it finishes) and the dash finishes, if im inside his collider i will get pushed underground

and eveything is in 2D yeah

[sterile reef]

Just Single (there aren't a ton)

[rigid island]

https://learn.microsoft.com/en-us/aspnet/core/fundamentals/dependency-injection?view=aspnetcore-8.0#service-registration-methods
Still trying to remember when to use Scoped, Transient vs Singleton 😅

[fallow quartz]

so like playerMask = forceSendLayer? doesnt work

[leaden solstice]

Even with that it is meaningful that you can run tests and can expand to multiple context if required

[heady iris]

I presume you've used = at least once before...

it assigns the value on the right into the variable on the left

[spring creek]

A layer is not a mask

[fallow quartz]

ok i think i got it

[sterile reef]

We should ask ourselves
Is playermask forcesendlayer

[leaden solstice]

Yeah very web focused categories tho

[rigid island]

haha yeah me working on a custom backend for a unity project

[fallow quartz]

so in that photo your making the layer of the object that has that collider apply to the layer of the playerLayer right?

[heady iris]

this is reading the forceSendLayers property of the collider and storing it into playerLayer

it does nothing else

notably, this does not change which layers the collider sends force to

[fallow quartz]

so if i want to deny the collision forces between 2 dynamic objects to interact I cant?

[heady iris]

you can, but not by writing whatever that code is

perhaps you want https://docs.unity3d.com/ScriptReference/Physics2D.IgnoreCollision.html instead. It allows you to ignore collisions between two specific colliders.

You could give the player some extra time to get out of the boss's collider.

[fallow quartz]

I use this a lot but wont work for this because i want the onCollissionEnter method to proc but not the forces between the dynamic objects to get applied

like if it was a trigger but without it being a trigger

[heady iris]

okay, then you need to update either the forceSendLayers of the boss's collider or the forceReceiveLayers of the player's collider

To make this easier, I would add two LayerMask fields: one for the normal state and one for the "ghost" state

[sterile reef]

Me turning on my PC knowing I have to rewrite my whole procedural melee swing code because it's too limiting for me to use

[heady iris]

the first one should have every layer included

the second one should have the player's layer excluded (if you are doing this on the boss) or the boss's layer excluded (if you are doing this on the player)

[knotty sun]

this is a channel for code questions not random ramblings

[sterile reef]

Oh wait yeah I forgot there were other channels 💀

[fallow quartz]

I think forces can even be deactivated in every enemy since i dont need them, the thing is idk how to deactivate the force

because i never used that force layer thing

[heady iris]

then just assign playerCollider.forceReceiveLayers exactly once in Start or something

[heady iris]

if you don't know how to do this, ask about it instead of skipping past it

[rancid frost]

How can i draw a set of meshes with random colors while reducing batch count?

Unity tilemaps is able to do this, but I dunno know

[fallow quartz]

in here forces are the same, what would it change if i swap layers and both apply forces

[heady iris]

I don't understand this statement

Are you asking about whether you need to configure the force layers on both the boss and the player colliders?

[fallow quartz]

No no, I think i might be understanding wrong your explanation but playerCollider.forceReceiveLayers makes the game just to receive force from the layers you design right?

So you need to go 1 by 1 declaring each layer?

[heady iris]

That property is a LayerMask.

it lets you include or exclude all 32 layers

you need to add a LayerMask field to your component and set it up in the inspector to include the correct layers

[heady iris]

I think tilemaps bake the color into the vertex data. Don't quote me on that one, though..

[fallow quartz]

okay give me a sec im gonna try

[fallow quartz]

okay done, I am stupid sorry, wasnt understanding correctly

You are insane ❤️

btw one last thing, if in the player start i just set that i can receive the force from none layer and in the start of the boss i send force to the layer of the player, at the end the player would receive the force cause im sending or it will just get bloocked because i set it up to none receiving? Imagine that both codes run at the same time

[heady iris]

The sending collider must want to send force to that layer, and the receiving collider must want to receive force on that layer

https://docs.unity3d.com/ScriptReference/Collider2D-forceReceiveLayers.html

see here

[fallow quartz]

so if i want to let everything at it is when i set up the layerMask i need to check every layer box except for the one i dont want to apply it right?

[heady iris]

correct

[fallow quartz]

Now I have another issue. I have a prefab for the player. On each scene i dragged a prefab of the player but when he is already in the hierarchy i changed some values cause i want him on some scenes with more hp than others. Now If I want to add something new to the player and apply on all of the gameobjects but without overriding the stuff that i changed for each of them, is there anyway? Or should I set it up in other way so i dont have this problem?

[heady iris]

Each prefab instance will keep its overrides.

so if the prefab instance overrides "foo" to be 100, changing "foo" on the prefab will do nothing: you'll still have a value of 100 on that instance

[fallow quartz]

so if i add something new with a certain set up directly to the prefab all the other values will remain the same on each gameobject?

[bronze crystal]

why my enemy is taking the last position of my player to chase him instead of contiously updating

at start my enemy goes to the first position from the prefab and then i stays stuck there.

[vagrant blade]

Because you never update the target position for the enemy. You've answered your question in your own second message.

[fallow quartz]

okay now i have another problem, i can move the enemies when i hit against them, before i couldnt

[heady iris]

correct; changing one component won't make every instance forget all of its overrides

that would be useless!

[heady iris]

since you no longer receive force from enemies, you're no longer pushed away when you walk into them

[fallow quartz]

but that doesnt explain why i can push them

I dont want to push them

and i only added the receive boxCollider.forceReceiveLayers = layersForced; statement so i shouldnt be able to push them

[heady iris]

enemies can no longer push you away

therefore, you can overlap the enemy

therefore, you push them away

[fallow quartz]

and to stop that from happening what can i do, i dont want to push the enemies

[fallow quartz]

using the receiveforces has any other secondary effect?

[heady iris]

If your problem is that the player is ending a dash inside of enemies and thus getting forced out suddenly, you should really just use IgnoreCollision

You could add a second trigger collider to the player that detects when you leave the enemy's collider, so that you can turn collision back on

[fallow quartz]

if i use ignorecollision the enemy cant hit me with his collider

[fallow quartz]

and the problem is not getting forced out, thats what i want, the problem is that i got forced underground not to the sides

[latent latch]

Few ways to go about this and ideally you just bake/reconstruct the whole mesh together with the vertex colors chosen at uv coordinates. Or, use sprite renderer and use its dynamic batching if you're using 2D

srp batching does work ok too if you do want to change via fragment and that you're using a single shader, but if you're not reconstructing/moving the meshes, then go with the bake solution

with chunks if large enough

[rancid frost]

I see, so instead of updating colors via the shader, we update the mesh colors directly

[gray spruce]

I used animation controller, and the player movement code is making the transitions possible

@heady iris the receiveforces has any secondary effect apart from the player pushing the enemy? And btw is there anyway to edit a tilemap without getting lag? I have a lot of tiles and its really laggy and a lot of times starts loading pop up, but if i edit in prefab mode each time i do something it also gets the pop up with the import

[rigid island]

if you want to use a rigidbody you should not move using Root motion / animation

[gray spruce]

How should I move?

[rigid island]

using the rigidbody

[gray spruce]

How can I animate a character that has gravity and a collider?

[rigid island]

with the same way you're doing it now ?

but just switch movement to rigidbody..

if you have to switch the animator

[gray spruce]

I found a solution right now. Instead of using the rigid body, I used a character controller. It's working!!

Thanks for the help!

Hey, I have this method, which calls a version of WaitForSeconds according to the code running in the Editor or not. Is there any way to implement a class the same way?

yield return AwaitForSeconds(1f);

private IEnumerator AwaitForSeconds(float seconds)
{
    yield return
#if UNITY_EDITOR
    Application.isPlaying ? new WaitForSeconds(1f) :
#endif
    new EditorWaitForSeconds(1f);
}

And my 2nd question would be about a better name for it

[wide dock]

And what exactly are you trying to do with a class that would require conditional compilation?

But sure, you can do it, as long as you don't break something obviously

[heady iris]

make a class that implements IEnumerator. Calling MoveNext should return true exactly once, and when it's called, you should set make Current be the (Editor)WaitForSeconds object

[leaden ice]

Unity offers this:
https://docs.unity3d.com/ScriptReference/CustomYieldInstruction.html
You can derive from this class

[gray mural]

Editor Coroutines would've probably implemented this in their code, had it been possible

[leaden ice]

Do they not?
I feel like I'm missing some context for this question

[gray mural]

Yeah, EditorWaitForSeconds is a completely different class with no parent.

namespace Unity.EditorCoroutines.Editor;

public class EditorWaitForSeconds
{
    public float WaitTime { get; }

    public EditorWaitForSeconds(float time)
    {
        WaitTime = time;
    }
}

This is its full version with just summaries removed

[gray mural]

Just tested it out and it perfectly does what I need. As usually, thank you for a perfect solution 🙂

[heady iris]

Note that this will produce just about as much garbage as using an IEnumerator method

you can make a struct that implements IEnumerator, but it'll get boxed when it's returned as an IEnumerator

[fallow obsidian]

if i have animations setup like the image, I should be able to play these animations with this code, right? ```cs
GetComponent<Animation>().Play("V_MoveLeft");

[heady iris]

well, you capitalized it wrong

[fallow obsidian]

oh

brother

[heady iris]

i don't use Animation (it's an ancient component) but that's probably not helping

[fallow obsidian]

sorry i got boomer eyes haha

ah its a project that was already setup, trying not to change a lot of stuff.

[fallow obsidian]

thank you for noticing

Hey my Unity editor isn’t installing. It’s stuck on Editor Application please help.

[tacit rover]

Good afternoon. I'm trying to implement a black overlay on the camera when the player falls out of bounds and/or dies, in order to reload the current scene and reset the player at the last checkpoint. The issues I've encountered are as follows:

• If I attempt to use SceneManager to add multiple scenes, based on what I've read, the objects in the 2nd scene can't perform actions on the canvas and/or camera in the first scene so I can't force a black-box overlay in front of the current camera while the scene reloads.
• If I create a black-box overlay and put it right in front of the camera, it'll just disappear once the scene is reloaded.

Maybe my approach to this is incorrect but how can I obtain the following order of actions?

• Player falls out of bounds/dies
• Create death overlay
• Reload Scene
• Remove death overlay

[snow lake]

My editor won’t download

[heady iris]

this is not a code problem

ask about your editor install in #💻┃unity-talk

also, !install

[tawny elk]

When Unity fails to install checklist

• Make sure you have enough space including on C: drive.
• Check that it's not being blocked by antivirus/security programs.
• Look through the logs for a real reason why the setup fails they are pinned [here](#💻┃unity-talk message).

If you still have issues, perform a clean install in another location:

• Install the Hub and Unity in a non-system drive or a clean new folder in the root of C: drive.
• Failing that use the recovery Refresh option or reinstall OS entirely then repeat the previous step.

[heady iris]

You can just put a second canvas in the second scene.

adjust its sorting order so that it winds up in front

[tacit rover]

I've tried that but it doesn't seem like the scene manager is loading the 2nd scene, at all.

[heady iris]

well, then that's the problem

you should figure that out :p

You might just want to put this "fader" in DontDestroyOnLoad

That is exactly what I've done

No need to deal with a genuine multi-scene workflow if this is all you'd be using it for

[tacit rover]

Is that ScreenFader just another game object with a canvas component on it? Or is there other pieces to implementing it that way?

[heady iris]

Yeah, it's a canvas with a single Image on it

[shell scarab]

You realize that if UNITY_EDITOR is not defined it will yield return the EditorWaitForSeconds object right? I don't think this is what you want.

[heady iris]

The conditional expression split across a conditional compilation directive is...a little too clever, yes

(you can use #else)

[shell scarab]

That doesn't even bother me Fen, it's saying that if this code is in a build do new EditorWaitForSeconds(1f) which will fail in a build.

[heady iris]

right, I just wondered if that hid the error

[shell scarab]

perhaps. I skimmed the conversation after that code snippet and didn't see it mentioned anywhere so I thought it worth mentioning.

[dapper schooner]

What would be the best approach to draw a grid that remains in the players face and only reacts to y rotation. so if I look up and down or tilt my head left or right it doesn't react.

I am using a fullscreen shader rght now. I created a variant of that and added the shader to a quad and made it a child of the VR rig. That works but the quad edges can be seen

[leaden ice]

"A grid" is really vague

could you explain that more

[dapper schooner]

OK so for example, lets say you have a VR game where the player is a camera.

Player presses a button to take a photo and whatever is in the players view is snapped.

What I am asking is what if there was another button that would bring up the rule of thirds grid.

Its always in your view (forward).

if we are uses axis then it only reacts to y rotations of the players head. Not X or Z rotations.

Im trying to figure out the best way to implement this without using a quad

[leaden ice]

Hmmm why should it only react to Y axis rotation? That doesn't seem right to me. Doesn't the rule of thirds just have to do with the actual viewport of the camera?

Even if the camera is pitched or dutched

[dapper schooner]

Maybe a bad example but the point is that I only want the grid that is shown in front of the player to always remain in front of the players forward but ignore x and z rotations. Just trying to figure out if I could do that with shaders

[leaden ice]

of course you could. YOu could also just do it with a simple script

[dapper schooner]

Think I am wording my searches wrong. I have been trying to find information on how to do it so that I do not have to recreate my fullscreen render feature shader graphs

[rancid frost]

Just wanted to thank you for the idea, I was able to implement what you stated

[void wedge]

Can someone help me figure out how to fix my inventory count problem? The problem is when the max stack size is reached (5) it goes into the next slot which is good, but instead of just starting the new slot stack at 1 it starts all the stacks with that item in it back at 1. Heres the code and some SS

InventoryManager:

using System.Collections.Generic;
using UnityEngine;

public class InventoryManager : MonoBehaviour
{
    private List<Item> items = new List<Item>();
    public Transform itemsParent; // The parent object that holds the inventory slots
    private InventorySlot[] slots;

    void Start()
    {
        slots = itemsParent.GetComponentsInChildren<InventorySlot>();
    }

    public void Add(Item item)
    {
        // Check if the item already exists in the inventory
        Item existingItem = items.Find(i => i.itemName == item.itemName);

        // If the item already exists and is stackable, increase its count
        if (existingItem != null && existingItem.maxStack > existingItem.currentStack)
        {
            existingItem.currentStack++;
        }
        else
        {
            // If the item is not in the inventory or cannot be stacked further, add it
            item.currentStack = 1;
            items.Add(item);
        }

        UpdateUI();
    }

    public void Remove(Item item)
    {
        items.Remove(item);
        UpdateUI();
    }

    void UpdateUI()
    {
        for (int i = 0; i < slots.Length; i++)
        {
            if (i < items.Count)
            {
                slots[i].AddItem(items[i]);
            }
            else
            {
                slots[i].ClearSlot();
            }
        }
    }
}

InventorySlot:

using UnityEngine;
using UnityEngine.UI;
using TMPro;

public class InventorySlot : MonoBehaviour
{
    public Image itemIcon;
    public TMP_Text itemCount;
    public Item CurrentItem { get; private set; }
    public bool IsEmpty => CurrentItem == null;

    public void AddItem(Item newItem)
    {   
        CurrentItem = newItem;
        itemIcon.sprite = newItem.icon;
        itemIcon.enabled = true;
        itemCount.text = newItem.currentStack.ToString();
    }

    public void ClearSlot()
    {
        CurrentItem = null;
        itemIcon.sprite = null;
        itemIcon.enabled = false;
        itemCount.text = "";
    }

    public void HighlightSlot(bool highlight)
    {
        if (highlight)
        {
            // Highlight logic here
        }
        else
        {
            // Unhighlight logic here
        }
    }
}

[latent latch]

I'd double check to make sure it's not just the UI displaying wrong first

[leaden ice]

Another thing to check is if your Item type is a class and therefore a reference type, and you're maybe reusing the reference multiple times in the inventory, but when you set the stack size for one, it sets for all, since there's really only once instance.

[void wedge]

yea the UI is correct, all of them have their own text linked. Before this I was having the problem of each new slot that added the next resource would start with the max stack size

I am using a class but let me check if im actually making a new item

[leaden ice]

   Item existingItem = items.Find(i => i.itemName == item.itemName);

        // If the item already exists and is stackable, increase its count
        if (existingItem != null && existingItem.maxStack > existingItem.currentStack)
        {
            existingItem.currentStack++;
        }
        else
        {
            // If the item is not in the inventory or cannot be stacked further, add it
            item.currentStack = 1;
            items.Add(item);
        }```
Based on this code you're not making a new item

[void wedge]

yea I think thats the problem, im just getting the info from the hit on raycast then putting it in inv from that

[leaden ice]

ALso I think what you're calling an "Item" here would be better named as Stack or ItemStack

[void wedge]

so I need to check what im hitting, create a new instance of the item, then add it?

[leaden ice]

and it should contain like:

Item item;
int quantity;``` for example

Or maybe Item should be an enum or a string or perhaps a ScriptableObject

[void wedge]

yea ive got an item class applied to each object

using UnityEngine;
using UnityEngine.UI;

public class Item : MonoBehaviour
{
    public string itemName;
    public Sprite icon;
    public int maxStack;
    public int currentStack;
    public bool hasHotbarPrio;
}

[leaden ice]

oh god it's a MonoBehaviour?

Why

[void wedge]

is it not supposed to be?

[leaden ice]

Make it a ScriptableObject

[void wedge]

ahhhhh I thought it really didnt matter so I went this route xD

[leaden ice]

then it needs to be attached to a GameObject? Which is extremely awkward

It matters quite a lot

[void wedge]

yea I just attach it to the gameobject

[leaden ice]

Like all of this stuff except for currentStack is NOT instance data

it's like.. static data that defines the item

100% a use case for ScriptableObjects

[void wedge]

Then how would I link the gameobject with the scriptable object?

[leaden ice]

Reference it in the inspector

[void wedge]

Would I have a field to drag the prefab into the script so when I place the prefab it always is linked to it?

[leaden ice]

what prefab

[void wedge]

like right now I have a cube that I call "Gold" with the Item class attached to it

[leaden ice]

Ok so.. when you make an inventory system, and items can exist in the game as well as in the inventory

you really need to separate the concepts of:

• The item data (name, icon, etc)
• The "in the world" version of the item (MeshRenderer? Collider? etc)
• The "in the inventory" version of the item (Pure data)
• The "in the inventroy UI" version (UI elements that draw the inventory data)

bullets 2 and 3 there should reference the actual data definition of the item, which can be a ScriptableObject

[void wedge]

Alright im going to learn how to do this so Ill get back to ya

[latent latch]

Hey, monos can work, but yeah usually you want to have it as data then insert it into a monobehavior wrapper when it needs to be on the scene

and seeing that you're doing stacking, it probably should just be data

[void wedge]

Im watching this video and I see why scriptable objects is better than what I was doing but he still added an Item class to the prefab even after making a scriptable object that represented that prefab?

[spring creek]

Likely for the mutable data?
Is he populating the item class with the data from the SO?
