[sour zealot]

im not a beginner

im just a beginner in this field

: )'

[potent sleet]

🙄 it's okay to admit limited knowledge so someone can better help according to that knowledge

[sour zealot]

can we move into code beginner?

and you help me there?

[potent sleet]

for next time. For now just look over the tasks I told you alredy

I already sent what to do

[sour zealot]

okay

[jaunty sleet]

will I get an error if I try to stop a coroutine that is not running?

and if so how do I check if it is running or not?

[heady iris]

maybe if you pass a null to StopCoroutine

but i'm pretty sure it's a non-error to stop a coroutine that isn't running, in general

[jaunty sleet]

ok, thanks

[buoyant arrow]

please ping with response

I want to have a sphere that serves as a boundary for a player. The sphere is large and transparent, and the player is within such sphere. Imagine the sphere is hollow.

I want collision to occur only when the player has collided with the inner surface of the sphere (imagine the sphere is hollow). However, I do not want collision within the sphere. How do I go about this?

[hexed pecan]

So you want basically a sphere collider but with its faces inverted?

Sounds like you need a MeshCollider

Make a sphere mesh, flip its faces/normals and use that as the meshcollider's mesh

[buoyant arrow]

Will try—thank you!

[hexed pecan]

Another cheap option is to use a distance check from the center of the sphere to the player and do manual checks that way

But im not sure if thats suitable for your use case. If you need actual collisions, use what I first suggested

[hushed needle]

Hello, I am watching a tutorial video for Unity and in that video that man wrote a few lines of code and when I wrote the same code I received an error (the video is from 8 years ago) is this because the video is old?

[hushed needle]

this code:

[somber nacelle]

it looks like gridWorldSize is a Vector2 but you are trying to divide a float by gridWorldSize and store the result in a float. are you certain you don't want to be accessing the individual axes of that vector2?

[simple egret]

Basic operators between common types haven't changed in years, so your code is probably different

[hushed needle]

this is his code:

[somber nacelle]

yours is different

[simple egret]

It's not the same

Near the end of the lines

[hushed needle]

i am blind

[dusk apex]

var mistake = 2f / new Vector2(10f, 6f);//Error dividing a float by a Vector2 - they cannot operate in this way.```

var mistake = 2f / new Vector2(10f, 6f).x;//Legal - dirty example```

[quasi lily]

How do I get third person shooting that doesn't shoot around corners like this

I've watched multiple tutorials and they all allow look at where the camera is focused on but it always allows the character to shoot backwards

[hexed pecan]

Whats going on here, are the bullets supposed to fly straight?

[knotty sun]

you are missing a .x and a .y at the end of those lines

[dusk apex]

This is the general coding channel, maybe ask your question in #💻┃unity-talk or the forums (assuming you're requesting a feature etc)

[quasi lily]

Well they seem to be colliding with the player but that's a separate issue

Ok well I can show the code it's just a lot

[dusk apex]

!code

[hexed pecan]

Use the physics layer matrix to get around that issue

[hushed needle]

yes...

I can't believe it.

[dusk apex]

Is the bot down? !code

[hexed pecan]

!code please

[signal moon]

hi would anyone spare 5 mins to help me solve one little frustrating and probbably very simple error with my buttons?

[hexed pecan]

Why not ask the question here like everyone else?

People will help if they can

[signal moon]

well, it would be easier if ill show it, bcs its probably not only code issue, and i dont want to spam

[dusk apex]

• Use paste sites to post large blocks of code.

• e.g https://gdl.space/, https://paste.ofcode.org/, https://hatebin.com/

[hexed pecan]

Dalphat is the bot now

[dusk apex]

Really didn't want to see the screen flood.

[hexed pecan]

Then show it? 🤔

[quasi lily]

https://gdl.space/esibuteviw.cpp

[hexed pecan]

Make a thread if youre concerned about spamminess

[quasi lily]

This is all the code it's just a lot of like inheritance stuff

oh wait and I need the code for actually shooting the bullet 1 sec

https://gdl.space/aqodecubuq.cs

This is the weapon script

The collision stuff isn't working as intended but the shooting technically is, it's just the approach seems to be wrong, but every tutorial I watch tells me to do it like that lol

[dusk apex]

Without looking too much into the code I would consider checking if the shot direction is in the same direction as the target point. The wall was behind the player but in front of the camera. You can use dot product to determine if they are in the same direction or not - positive would be both facing the same way whereas negative would be the opposite (target was well behind the player!)

[signal moon]

ok, i wanted to show somebody on stream but ok, so i have this piece of code. i done it partly with chat gpt bcs i post things here when chat cannot help. ```using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class Przyciski : MonoBehaviour
{
public ProgressBar xp;
public Abilities ability;
private Button button;

void Start()
{
    // Get the button component
    button = GetComponent<Button>();

    // Set the normal color to 110E0E
    ColorBlock colors = button.colors;
    if (colors == null)
    {
        colors = new ColorBlock();
    }
    colors.normalColor = new Color(0.066f, 0.055f, 0.055f);
    colors.colorMultiplier = 1;
    button.colors = colors;
}

public void OnClickLaser()
{
    if (xp.SkillPoints >= 1)
    {
        ability.laser = true;
        ability.laserPoints++;
        xp.SkillPoints = xp.SkillPoints - 1;

        // Set the button's colors to white
        ColorBlock colors = button.colors;
        colors.normalColor = Color.white;
        colors.highlightedColor = Color.white;
        button.colors = colors;
    }
}``` later parts are basically the same thing but for different buttons. i want the buttons to be almost black, then when highlited to be white, and when clicked and function is played to stay white forever. my error message is NullReferenceException: Object reference not set to an instance of an object

Przyciski.Start () (at Assets/Skrypty/Przyciski.cs:18)
(its a full one)

[dusk apex]

You've got a null reference exception error on line 18

What line is 18?

[signal moon]

ColorBlock colors = button.colors;

[dusk apex]

So button was null.

[simple egret]

And indeed, there's no Button aside this script in the Inspector, so the GetComponent<Button>() earlier fails

[dusk apex]

Quick tip: GetComponent can return null.

[signal moon]

and how do i fix it? im a beginner, thats why i even asked this question

[simple egret]

Also note that we don't help with code that's generated by AI

[dusk apex]

It would return null when you've not got a button on the same object.

[signal moon]

the script is attached to both button and canvas

[wide terrace]

The canvas does not have a button component

[dusk apex]

For best practices, have the reference variable as public or [SerializeField] private and drag/drop the object into the Editor's inspector field.
You'd remove the GetComponent call if doing so in this way.

[signal moon]

ou

[simple egret]

Yeah having that script on the Canvas itself isn't logical

[signal moon]

ok, i thought that it will aply to children and then i changed the code again so its on every single one of them

so its useless by now

[simple egret]

The code explitly says "get a Button on this object", so placing it on an object that has no Button may result in the error you're getting

[signal moon]

ok thx its solved

but since im here, ill ask for help with my last error, that is also the same topic, and same error, but with different things

so

ProgressBar.Update () (at Assets/Skrypty/ProgressBar.cs:34)``` my code is ```using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class ProgressBar : MonoBehaviour
{
    public HeroKnight heroknight;
    public Image ProgressBarImage;
    public int AllEnemies;
    public int DeadEnemies;
    public int PlayerLevel = 1;
    public int SkillPoints = 0;

    private void Start()
    {
        // Count the number of enemies in the scene
        GameObject[] enemies = GameObject.FindGameObjectsWithTag("Enemy");
        AllEnemies = enemies.Length;

        // Call UpdateProgressBar to set the initial progress bar value
        UpdateProgressBar();
    }

    private void Update()
    {
        // Call UpdateProgressBar every frame to update the progress bar value
        UpdateProgressBar();
        if(AllEnemies==DeadEnemies)
        {
            DeadEnemies = 0;
            SkillPoints++;
            PlayerLevel++;
            heroknight.currentHealth = heroknight.maxHealth;
        }
    }

    private void UpdateProgressBar()
    {
        // Calculate the fill amount based on the number of dead enemies and the total number of enemies
        float fillAmount = (float)DeadEnemies / AllEnemies;

        // Set the fill amount of the progress bar image
        ProgressBarImage.fillAmount = fillAmount;
    }
}```  the error occurs when i kill all enemies, so when if(allenemies....) is triggered

it wasnt there before i done my buttons

[dusk apex]

at Assets/Skrypty/ProgressBar.cs:34
The number 34 above indicates that it occurred on line 34.

[signal moon]

but line 34 is heroknight.currentHealth = heroknight.maxHealth;

[dusk apex]

Wherever that may be

So an NRE occurs when you try to access a member of something null.

heroknight was null (which is fine) but because you tried accessing currentHealth and or maxHealth, the error occurred.

[quasi lily]

ok sweet fixed that issue thx ppl

[dusk apex]

Luckily they were both the same reference so you did not have to play guessing games. heroknight was null. Figure out why.

[signal moon]

might it be the issue with progresbar not being attached to heroknight?

[signal moon]

nah its not it

[wide terrace]

Your code doesn't seem to assume it would be attached to a heroknight. I would guess that you haven't dragged an object into the Heroknight field in the inspector

[winged tiger]

obj.Translate(obj.forward * moveSpeed * Time.deltaTime);

why in the world this moves the obj on the global x axis

[wide terrace]

presumably because obj's z axis is aligned with the global x axis?

[winged tiger]

no

it's rotating

[simple egret]

Nah it's because .Translate is alrealy local space

[wide terrace]

ahhh

[winged tiger]

oh and that

[simple egret]

You need to do Vector3.forward * ...

[signal moon]

you are right

[winged tiger]

Vector3.forward * obj.rotation?

[simple egret]

• deltaTime, but yes

[signal moon]

idk if thats good or bad, couse my problem isnt occured by errors

but atleast now i know whats going on

Thank you!

[winged tiger]

now I have no idea what direction it's moving. Not on local z axis

[simple egret]

Post the new line of code, as well as obj in the scene with the move tool arrows visible, and in Pivot + Local mode

[winged tiger]

obj.Rotate(obj.up,rotateKosiarka);
obj.Translate(obj.rotation * Vector3.forward * moveSpeed * Time.deltaTime);```

[winged tiger]

in that rotation it's moving on the global x axis

[simple egret]

Still not good, why did you multiply with rotation?

This makes the resulting vector local again

[remote abyss]

If anyone can help me pls, not sure what is going on. I have a particle effect as a PreFab. If I put it on a missile with a force and when I place the missle in the scene by itself it will fly into another object and explode and the particle effect plays correctly. But I instantiate it from the spaceship, the firepoint is placed WAY of the spaceship object just to test even and as soon as I fire the missile it explodes underneath he ship itself no matter how far out I put the firepoint?

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

public class MissileController : MonoBehaviour
{
    public float missileSpeed = 30f;
    public Rigidbody rb;
    public GameObject hitParticlePrefab;

    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void Update()
    {
        rb.AddForce(transform.up * missileSpeed);
    }

    private void OnCollisionEnter(Collision collision)
    {
            Instantiate(hitParticlePrefab, transform.position, Quaternion.identity);
            Destroy(gameObject);             
    }
}```
Here is the code on the missile to trigger on impact. What am I missing pls?

[winged tiger]

ohh

wait

.Translate is local

ah man

[remote abyss]

bah code block didnt work 😦

[winged tiger]

put the code in code

3 times `

[simple egret]

Backticks ```, not quotes

[remote abyss]

yeah noticed lol sorry

[simple egret]

That script is on the root of missile prefab right? Not anywhere else nor any of the prefab's children

[quaint crypt]

how do I convert from whatever Object type LoadAssetAtOath returns to my generic T type?
T prefab = AssetDatabase.LoadAssetAtPath<T>(path);
It gives an error saying there is no type conversion from UnityEngine.Object to T, and no boxing conversion.

[simple egret]

Constrain your type to what it needs, at the class declaration: class C<T> where T : Object { }

[remote abyss]

@simple egret Correct. script is only on missile

[simple egret]

Okay, can you Debug.Log the position of the missile when it collides with something? And verify that the position is the one you're expecting (ie. the hit point, not your spaceship pos)

[remote abyss]

@simple egret Bah good suggestion, thx man. I do that all the time just dont know why I didnt think of doing that now lol.

Im like the Debug god normally lol

[remote abyss]

@simple egret Thx man fixed it. Got some wierd unknown to man reason I had added a
missile.transform.position = transform.position;. LOL

[heady iris]

the missile knows where it is...

[remote abyss]

Hehe yeah

[shrewd meteor]

sure (sorry for the late reply, I got caught up in something)

Can anyone help me with a coding problem?

[potent sleet]

https://dontasktoask.com

[dim gale]

sorry

this is the basic idea of my app

when you press add a input field comes up asking you to type in how much money you want to add

same for subract

[potent sleet]

so what's the problem ?

[woeful slate]

If I have a WebSocketClient that I'd like all my characters to be able to access, what's the best way to do that? A singleton with the instance?

[dim gale]

the code part for subtract works but not very correct and the part for adding doesnt work at all

when you subract once it works but subtracting multiple times doesnt add it to the last one just resets it

and the code for adding is the same like for subtracting but it doesnt work

[potent sleet]

show code

[dim gale]

sorry if i sound stupid

DODAJ means add and ODUZMI means subract in my language

[potent sleet]

ugh dyno

idk why bots asleep

[dim gale]

yeah doesnt work

can you still see the code?

[potent sleet]

no use a site I can't read lines

[dim gale]

what site

oh

wait

[potent sleet]

it's in the readme

[regal epoch]

when I run my game on my phone, lock the screen, and turn my phone on again, the game is viewed on top of the lockscreen. Anyone know how to get rid of this "feature"?

[potent sleet]

this isn't a code question

[dim gale]

.

[regal epoch]

It's a unity question that could maybe be solved by code

[potent sleet]

I said a site from #read me dude

[regal epoch]

idk

[potent sleet]

it's not

[regal epoch]

why not

[dim gale]

sorry

https://paste.ofcode.org/33yyy62baDJPTi2MZsJ539i

[potent sleet]

btw Textmeshpro component comes with functions similar to regex

[dim gale]

never heard of regex

[potent sleet]

you can just make the field "numbers only"

so you dont have to do this
float.TryParse(ODUZMI.text, out float result2);

[dim gale]

yeah i did that

oh

idk how other i would do it

[simple egret]

Also if you're using TryParse, actually use the bool it returns to clear the input if it couldn't be converted to a number!

Or show a message to the user, whatever

[dim gale]

okay but why does the subtract code work fine but the add code not

[potent sleet]

or decimals if you use decimals

[dim gale]

yeah i made it decimal already

but i dont know how i would save it in code

without using tryParse

[simple egret]

You need that, or Parse since you're sure it's a number already

[dim gale]

parse didnt work

[simple egret]

The issue lies in the part where you add or subtract

[potent sleet]

oh true

thought InputField has a method or something

[dim gale]

i honestly dont see it

sorry im new to coding

[potent sleet]

anyway
moneyAll = +moneyNumberAdd;
change it to
moneyAll += moneyNumberAdd;

[simple egret]

You do a = + b instead of a = a + b

Or, a += b which is a shortcut

[potent sleet]

^

[dim gale]

ohhhhh damnnnn

i feel so fricking dumb

works perfectly fine now

thank you @potent sleet and @simple egret

appreciate it❤️

[potent sleet]

this is strange though
DODAJ.GetComponent<InputField>().text

DODAJ is already InputField

just do DODAJ.text

[dim gale]

oh

yeah didnt see that

well thank you

[simple egret]

And for the parsing, you can do float n = float.Parse(DODAJ.text). It raises an error if what you pass isn't a valid number, but as the input field constrains your input to a valid number, it won't ever raise the error

TryParse is more for the cases where you don't have a constrained input, or you don't trust the user

[shrewd meteor]

nope, capsule still going through the floor

[potent sleet]

You commented out all those things ?

and saved

you saw edit too ?
You should only have
PlaceOnNavMesh();
running in start

[shrewd meteor]

yeah, I've realised the true problem, for some reason, the line "_Agent = GetComponent<NavMeshAgent>();" puts the capsule in the floor. I have no idea why seeing as the gameobject it's attached to is not (4.50, 0.08, 0.00) and i dunno where it's getting these coordinates from

[potent sleet]

do you have any components on the capsule ?

[shrewd meteor]

literally the moment I activate the NavMeshAgent, it get's "0.08" on the y axis from somewhere

[shrewd meteor]

this is all that's on the capsule

[potent sleet]

probably the navmesh

[shrewd meteor]

but I don't understand "how" that's happening as the navmesh is not at "0.08" on the y axis. So where is that number coming from?

[potent sleet]

did you disable all movement methods and only get navmeshagent

[barren void]

is there a way to convert this event to hold event?

        _decrementButton.onClick.AddListener(OnDecrement);
        _incrementButton.onClick.AddListener(OnIncrement);```
Cause it's time consuming when the decrement/increment action only triggers per click. Is there a onPressed function?

[potent sleet]

also try just
[SerializeField] private NavMeshAgent _Agent;
and setting it in the inspector

[shrewd meteor]

yep, it's not moving

[potent sleet]

so something is wrong in one of the movements scripts

[shrewd meteor]

well, I disabled them, so they're not meant to move

[potent sleet]

make your own button with image component and use
IPointerDownHandler & IPointerUpHandler

[potent sleet]

yes but now you can narrow down which one is giving issue

[barren void]

is this own button, a new class inherited to Button?

[potent sleet]

no

you make a script and put those two interfaces with their respective implementation

then use image component instead of Button

[barren void]

ohhh I get it, so its like overriding the default button script

[potent sleet]

using UnityEngine;
using System.Collections;
using UnityEngine.EventSystems;
 
public class MyButton : MonoBehaviour, IPointerDownHandler, IPointerUpHandler {
 
public bool buttonHeld;
 
public void OnPointerDown(PointerEventData eventData){
     buttonHeld = true;
}
 
public void OnPointerUp(PointerEventData eventData){
    buttonHeld = false;
}
}```

you can reference the Image component if you wanna change the sprite

or color

[barren void]

but the pressed/unpressed anim like state will be removed right? the base and pressed color what I meant

[potent sleet]

read what i wrote under it

[shrewd meteor]

well I think it's the warp, but I have no idea why. It says it's "Cannot teleport Guards to (4.50, 0.08, 0.00)" but it shouldn't be warping it there as the floor's position is "0,0,0" so I don't know what's going on. Why does it want to warp there?

[potent sleet]

the sample position is returning whatever it's trying to warp to

[barren void]

okay thank you, overhaul it is

[shrewd meteor]

well, it's meant to be where the Hit navmesh leads, but why is it then telling it to warp at 0.08 at the y axis?

[potent sleet]

first you added extra Warp above the If statement

try debugging visually hit.position
I have no idea where 0.08 is

[shrewd meteor]

nah that's the only warp

[potent sleet]

bruh

you have 2

on which doesn't belong

the proper usage is the if statement one

also like i said 0.08 sounds like the navmesh height from the ground if ground is at 0,0,0

[shrewd meteor]

yeah I think that's what it is

I'm starting to think this is going back to changing the pivot point

[potent sleet]

the pivot should not matter unless SamplePoistion of 1.0f was too small

which it isn't since it's returning the sampled position

or maybe it didn't

you should debug it since it's an If statement

if(NavMesh.SamplePosition(etc..
...etc
else

Debug.Log("No valid Position on Navmesh found")```

[shrewd meteor]

cranked it up to 10 and still same problem

I'm so damn confused

[potent sleet]

did you try logs

in the sampleposition

if warp is running though it does find a valid position

[shrewd meteor]

wait, where do I put this? In PlaceOnNavMesh()?

[potent sleet]

 private void PlaceOnNavMesh()
    {
        NavMeshHit hit;
        if (NavMesh.SamplePosition(transform.position, out hit, 1.8f, NavMesh.AllAreas))
        {
            _Agent.SetDestination(hit.position);
        }
    }

just try this

[shrewd meteor]

get this instead

[potent sleet]

it's because hes not on the navmesh

try deleting this agent and make a new one

test same script with new agent

[shrewd meteor]

aight bet

[potent sleet]

make sure you baked the correct navmesh too

correct layers and all

[shrewd meteor]

okay so I've created a new agent and all, anything I need to change in the script?

[potent sleet]

no try same line

[shrewd meteor]

nope, same error

[potent sleet]

click the floor and show me inspector tab under Navigation tab , show the Object tab

[potent sleet]

uh do you have a navmesh surface on the the ground ?

[shrewd meteor]

ye

[potent sleet]

show inspector for that component

I have a scriptable object that serializes abstract classes. Though, every time I want to add a new class to the list, I have to recreate the scriptable object. Is there a workaround for this?

public class D_Abilities : ScriptableObject
{
    [SerializeReference]
    public List<Ability> abilities = new List<Ability>
    {
        new MagicSeedAbility(), // abstract class
        new SummonPlagueAbility()
    };

    public GameObject abilityPrefab;
}

[leaden ice]

Write a custom editor script that gives you a UI that can add things to the list

Otherwise there's no way to choose what kind of ability to add in the UI

Hey, I have an array of Spell, which is a struct. I want to either assign it or not depending on the player having a spell equipped at that slot.
How do I check if it's assigned or not?
I tried spells[i] == default(Spell), however the compiler says that I can't compare Spell and Spell (?)
Also heard of nullable value types, not sure how I accomplish that

[rotund bison]

There are a few libraries that exist to deal with the editor if you just wanna get it over with

I think one of them was called SerializeReferenceExtensions or sumtn

think Odin also has something that does it

[leaden ice]

• Use a class instead of a struct if you want it to be able to be null.
• Give the struct an "is valid" bool
• use a parallel array with bools
• use an array of nullables

[golden vessel]

My instinct was to add a bool but that's redundant.

[golden vessel]

Do you have any idea why checking against default doesn't work?

[somber nacelle]

the bool is pretty much how nullable structs work anyway

[golden vessel]

Spell[] spells = new Spell[5];
if (spells[i] == default(Spell))
I'm pretty sure they are the same type

[golden vessel]

Makes sense ^^

[leaden ice]

Because you haven't implemented any way to compare your structs

You have to define the == operator for it

[golden vessel]

Ho damn

[leaden ice]

Equality checking works differently for value types than it does for reference types

[golden vessel]

Ok, good to know

[leaden ice]

There's a default comparison for reference types that uses the object address

Structs don't use reference variables so that can't be done in C#

[golden vessel]

Well I learnt something

Thanks ❤️

[lusty dragon]

Guys have you got any idea as of why the clamping does not work and it just keeps my vertical movment at 0?
instead of 0 to -90

  private void FixedUpdate()
  {
    float angleY = 0;
    float angleX = 0;

    if (turning)
    {
      // Calculate the rotation angle and direction
      angleY = turnSpeed * Time.fixedDeltaTime * (turnRight ? 1f : -1f);
    }

    if (_tilting)
    {
      // Calculate the rotation angle and direction
      angleX = tiltSpeed * Time.fixedDeltaTime * (_tiltUp ? 1f : -1f);
    }

    // Apply the rotation on global axes
    transform.eulerAngles += new Vector3(angleX, angleY, 0);

    // Clamp the x-axis rotation between -90 and 0 degrees
    Vector3 currentRotation = transform.eulerAngles;
    currentRotation.x = Mathf.Clamp(currentRotation.x, -90f, 0f);
    transform.eulerAngles = currentRotation;
  }```

[somber nacelle]

eulerAngles are interpreted from the quaternion at the time you access them. this means they can be either signed or unsigned depending on how they feel at the time you access it. This also makes clamping an axis on the eulerAngles property after rotating it harder than just manually tracking your rotation as a float and clamping that before assigning it to the rotation

search "clamp rotation" in this discord and you'll see plenty of examples of how you could do so

[humble temple]

anyone know why a meshrenderer with its materials array, having two elements in it, will create instanced versions of those materials during runtime? this seems to be what is preventing me from chaning the materials during runtime with a script

[quaint rock]

how are you trying to change it via script

its the accessing via render.material that is making them instanced

[humble temple]

in my script i have Material mat1, mat2, mat3 and so on. the materials are dragged into the inspector.
the script looks like this

tabletMesh = GetComponent<MeshRenderer>();


tabletMesh.materials[1] = mat4;

[rain minnow]

https://docs.unity3d.com/ScriptReference/Renderer-materials.html

[humble temple]

my code above was my first attempt.

[humble temple]

in reply to this suggestion, here is my new code:

tabletMesh = GetComponent<MeshRenderer>();

private void ChangeMat(Material mat)
    {
        mats = tabletMesh.materials;
        mats[1] = mat;
        tabletMesh.materials = mats;
    }

...//other code///
void Update()
{
if(somethig)
ChangeMat(mat4);
}

[rain minnow]

accessing materials instantiates the materials and makes them unique to this renderer. that's why they are instanced, bc they only affect this object . . .

[rain minnow]

this should work . . .

[humble temple]

ok, that makes sense. so what is the right way to change the materail during runtime?

you think it should work? darn. its not.

actually i think it is.

[rain minnow]

hmmm, that's weird . . .

[ashen yoke]

material property block

you mean swap? you can swap material just swap sharedMaterials

material is a getter for the currently used material, if it was unchanged it will return the original shared material, which is the asset

if you assign anything to it it will either assign the new or create a copy

to protect the asset from changes

if you didnt assign anything and didnt change you can just swap shared material for another asset reference

[quasi lily]

Why am I getting Cannot resolve symbol 'Invoke' and Cannot resolve symbol 'Instantiate'

Like they just don't exist in the context of this interface

But the entire enemy script is based around interfaces so like what am I supposed to do to instantiate the enemy projectiles

[leaden ice]

Those are methods on Monobehaviour and UnityEngine.Object respectively

If you're writing an interface, they don't exist unless you defined them

[quasi lily]

So like

Is there any way I can implement this in my interface?

[leaden ice]

Sure, add those to your interface

[quasi lily]

Like code Instantiate and Invoke myself??

[leaden ice]

No

Just add them to the interface

Interfaces don't contain implementation

Just the signature

[leaden ice]

Actually Instantiate is a static method anyway

So there's no need to do anything with Instantiate

[quasi lily]

wait it's not even an interface

its a class that implements an interface

I could just also get it to inherit from Monobehaviour then right?

[leaden ice]

Did you forget to derive from Monobehaviour?

[leaden ice]

I mean sure if you understand what Monobehaviour is

And what that means for your class

[quasi lily]

I do not really but no red line makes brain happy 🙂

If it breaks later then like

idk what isn't breaking atm

[leaden ice]

It's one of the most basic things in Unity scripting

Monobehaviours define components you can attach to GameObjects

[quasi lily]

I mean I just know it as script thing with all the main unity commands

[leaden ice]

Do you know what a component is

[quasi lily]

yeah like something you attach to an object

[leaden ice]

Yes

When you make a Monobehaviour class you're making one of those

If it's not a MonoBehaviour it can't be attached to GameObjects

You have to manage it yourself in code entirely

[quasi lily]

yh I get that

it doesn't seem like it will mess up the system so yeah it should be fine

[leaden ice]

Presumably you know if this class is going to be attached to a GameObject or not

[quasi lily]

it wont

but like

that shouldn't matter

[leaden ice]

If it won't be then it cannot be a Monobehaviour

It matters a lot

Invoke will definitely not work on it for example

[quasi lily]

ah

dope

uh

[leaden ice]

Why do you want invoke anyway

[quasi lily]

yeah ill be real I'm finished bro it

like I just was given a script with a statemachine class

each state is implemented as an interface

and it switches between which state is being executed

[leaden ice]

Sounds like you're in over your head a little

[quasi lily]

No shit lol

But it was like the code we were given and it works until I have to extend it to make the enemy shoot instead of just patrol

because shooting requires invoking a firing script on a delay and instantiating a bullet prefab, something the current implementation doesn't seem to allow for

maybe I just put the shooting code in the actual object that holds the state machine

[sterile island]

I need some help determining which tile the mouse is over when hovering. This is the code I have so far that seems to be the general goto. But I am having issues with the worldPos result being wonky and not mapping to a proper cell.

var mousePos = UnityEngine.Input.mousePosition;
mousePos.z = 1f;
var worldPos = Camera.main.ScreenToWorldPoint(mousePos);
var mapCell = _terrainTileMap.WorldToCell(worldPos);
var tile = _terrainTileMap.GetTile(mapCell);
if (tile == null) return;

The Grid position is 0,0,0 along with the tilemap within it being 0,0,0. The Camera will zoom in and out as part of the controller. I have been stumped on this for hours and every search result comes up with this same solution. But no matter what, the mapCell is always the same. Im not sure what I could be missing here.

[quaint rock]

what mode is the camera in, perspective or ortho

[sterile island]

It is Perspective

[quaint rock]

ScreenToWorldPoint will not do what you think then

it gets a point on the near plane of the camera

you want
https://docs.unity3d.com/ScriptReference/Camera.ScreenPointToRay.html

then you can use the resulting ray, to get a position in the world, by raycasting

[thorny sparrow]

Hello. If I have multiple of the same script on one object, how can I reference one of them specifically?

[quartz folio]

Drag a reference to it into a serialized field

[sterile island]

Ah I see with the camera part. I changed it to ortho since I really didnt need it perspective. Now things are changing so I will try working from that. Thanks @quaint rock

[thorny sparrow]

it doesnt let me drag it in

[somber nacelle]

are you using the correct variable type?

[quartz folio]

Then show what you are trying to drag, and to where. Nobody can help without full context.

[quartz folio]

It's unclear where these two objects are, are they both in the same scene?

[thorny sparrow]

one is a prefab

[hidden compass]

Hello, i think i need an extra pair of eyes.. Here in the video, is an enemy ai, the smaller orange circle is the radius of this next script..
i run a foreach with an overlapsphere and check the players velocity to see if he's moving.. if he is -> we update his position.. if not do nothing.
then cs private void Update() { ForgetSounds(); } runs continuously.. to forget everything after so many Ticks

he shouldn't be updating the player's position unless he's still inside that orange circle.. but here u can see the orange line draws my position until he forgets the sounds.. which is fine, but it should forget the last position he heard the player within that sphere , had the player exited it..
https://www.spawncampgames.com/paste/?serve=code_508

heres the code... something going on in that foreach or something that i dont understand

oh, you can see how the vision one stops and turns magenta when the player exits.. yet the hearing one doesn't 🤔

    private void OnDrawGizmos()
    {
            Gizmos.color = drawColor;
            if(DetectedPlayer && Player) // && player
                Gizmos.DrawLine(sensePos.position,Player.transform.position);
            else if(Player && !DetectedPlayer)
                Gizmos.DrawLine(sensePos.position,playersLastKnownPosition);
    }``` these are the gizmos

adding in player= null; and DetectedPlayer = false at the beginning of the Tick() fixed it for for not detecting once outside the radius but.. then it breaks the ForgetSounds() function..

imma have to think about this one..

This script is attached to an empty GameObject. The function CreatePlayField is assigned to a button's OnClick event. Now the button works, I have tested it with Debug.Log . But it does not generate the plane I want it to in this function. There is a debug.log in Update function I used to know how this function works. That debug statement tells vector difference between positions of a Quad and generated plane. The debug text is empty which alludes that the plane is not generated. The quad is there. The plane is not. Can someone tell what I might be doing wrong here ?

Some screenshots are attached for better understanding

[simple sable]

Hey everyone.

So I have this script that chooses a random position in my world and I want to check if that point is inside of a collider. I searched on the internet on how to do it and I ended up with this line of code.
Then, I check if "collider" is null or not and that should tell me if the point is inside a collider or not. But for some reason, it doesn't work, and I'm not sure why.

[ashen yoke]

what doesnt work

the null check? the overlap?

are you sure the collider is on layer 6?

[simple edge]

Fairly sure layermask needs to be bitshifted
Try 1 << LayerMask.LayerToName(6)

[somber nacelle]

only if you aren't using LayerMask.GetMask. also LayerToName returns a string which you cannot bit shift anyway

[simple edge]

Ah fair enough

Yeah I was thinking of NameToLayer

[simple sable]

Yep, my Tilemap Collider 2D is on that 6th layer.

The null check always returns false, even though I can see in the scene view that the point is inside of a collider by just spawning an object at that position.

[ashen yoke]

1 << 6

[simple sable]

I'm not sure what that means.

[simple edge]

Shift it to the left 6 times

[somber nacelle]

i mean a better option than manually bit shifting is just to create a LayerMask variable that you set in the inspector

[ashen yoke]

yes

[simple sable]

I'll try that.

[somber nacelle]

also it sounds like you might have a specific collider you are checking against, if that is the case why not use Collider2D.OverlapPoint instead?

[cosmic rain]

0100 0000

[ashen yoke]

0010 0000

cat_at_the_table_girl_screaming.jpg

[cosmic rain]

Does that mean that 1<<1 is 0000 0001?🤔

[somber nacelle]

i'm gonna have to agree with dlich on this, 1 << 6 is 64

https://dotnetfiddle.net/Doh6y6

[simple sable]

Because the script that checks the collision is on a prefab, I thought it would be more effective using Physics2D.OverlapPoint than trying to find my tilemap in the scene to get the collider from it.

[somber nacelle]

ah, fair enough

[simple sable]

Works just like before, in the sense that it always returns null.

[ashen yoke]

yep im off to reeducation center

1 << 0 is 0001

My movement script is messed up. When I try to walk or sprint, I don't move, but if I let go of sprint, I get kind of catapulted forwards and stop slowly. Can someone help?

[cursive moth]

this sounds to me like you messed up input checks, could you send the code following the #854851968446365696 rules?

[ruby fulcrum]

is it alright to have functions with non capitalized letter at the start

i just saw the naming convention warning but all my functions are already non capitalized

[winged mortar]

It's not convention to have them lower case start

[ruby fulcrum]

but would it affect the performance

[winged mortar]

And pretty much everyone uses PascalCase

No

Not at all

[ruby fulcrum]

ah alr then

[winged mortar]

Functionally not different

Make sure you are consistent with your naming though

It reduces visual load when trying to read your code back

[ruby fulcrum]

i name my coroutines with capitalized at the start

[winged mortar]

It instantly becomes clear that you are looking at a function

[ruby fulcrum]

and functions with non capitalized

[winged mortar]

Now that's confusing

[ruby fulcrum]

think that helps to differentiate

i mean it works for me

i saw the warning for coroutine and assumed all coroutines needed pascal

didnt know it applied to functions too

[winged mortar]

If it works for you then it's fine

https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/coding-style/coding-conventions

Might be worth checking it out

[thin aurora]

In c# you would usually capitalize them. It's honestly just preference, though. Javascript and such all have them non-capitalized, for example

You can disable the warning, if you would like to stick to it

There's really no "best" way with this. There's just the way that the majority of people considered best practice, and nobody forces you to stick with it

[halcyon radish]

Hey, morning guys, i've been getting a "A Native Collection has not been disposed..." error regarding memory leak when doing a web request. This has only started showing when I upgraded to 2021.3.6f1, which was a few months ago.

Before we where using 2020.### (don't remember the exact version), but as we upgraded my computer at the start of the year we decided to upgrade the version of unity we where using. Because we had a few other features to work through, I didn't think to address this issue until now. I do have the web request wrapped in a using statement and also call dispose at the end of the call. Even while I do so the error still appears.

It may be obvious to someone else what I might be missing, i'll attach screenshots of the error and the code snippet. If you need any other clarification just let me know.

[thin aurora]

Do you use native arrays at all?

Also, side note, suggest you look into Newtonsoft when it comes to serializing data to JSON

JSONUtility is very bad

[halcyon radish]

Nope, i'm not at all.

[swift aspen]

should you really be disposing your webRequest when using implicitly disposes it?

[halcyon radish]

Ahh thanks for that side note, i'll look into Newtonsoft.

[halcyon radish]

I was just thing to think of whats to resolve this issue.

In the stack trace it was pointing to my request script, which is why I thought i would need to dispose somewhere along the line.

[swift aspen]

Looks like you're not disposing the DownloadHandlerBuffer. Try adding webRequest.disposeDownloadHandlerOnDispose = true

[halcyon radish]

Can Newton Soft handle parse an array json string? Which I currently use a a JSON Helper as a work around.

[thin aurora]

An array as json that needs to be deserialized into an actual array? Yes

It's one of the many things JSonUtility can't do

You would need to wrap it around an object, lol

There's a whole lot of things it can't do, hence why I strongly suggest you ditch it asap

[halcyon radish]

In the previous screenshot I added it at the end of the using statement for the web request. But the error still shows up.

[swift aspen]

Which screenshot? You added the upload not the download

also the UploadHandlerRaw also needs the dispose from the looks of it

[halcyon radish]

I was referring to my initial post.

[swift aspen]

So try removing your manual .Dispose() while keeping both dispose...OnDispose = true

[halcyon radish]

this one.

[swift aspen]

Yeah exactly you only did for Upload, you need to do it for Download as well

[halcyon radish]

Ohhhhhh, my mistake. Got you.

Let me try that.

[swift aspen]

Both of those types, UploadHandlerRaw and DownloadHandlerBuffer mention that they allocate Native Memory. Whenever something allocates native memory you need to dispose it somehow. In your case the UnityWebRequest seem to be able to do it for your through the dispose...OnDispose functions

[halcyon radish]

Amazing, thank you so much, yeah, I was missing just disposing the download. Thank you I was racking my head with this. It makes sense when I think about it, because i'm receiving data too.

I though the using statement would handle that disposing of the data, rather than me having to set the function to true.

[soft igloo]

a simple traffic simulation project

I'm not sure there's such a thing. At least not for free.

[burnt echo]

Hey, so I'm trying to do some decoupling, I feel like my stuff is getting really spaghetti'd and I'd like to do a clean up before I continue and make the project bigger.

I have 5 singleton systems/managers, including a GameManager, and they're all just referenced where I've needed them.

Could someone point me to some resources to clean up all my references? Maybe give me the name of a better design method I could research?

[cosmic rain]

Well, it depends on what these managers are doing and where/what for you reference them.

[burnt echo]

Actually make it 4, I forgot one is just the scene controller, I don't think I need to count that. Lol

I'm doing a kind of idle/resource management game that's all UI based so each of the current singletons are set up for tracking and handling different "resources".

RosterManager handles the minion counts, as well as assigning them to different jobs (sub-rosters).

I have an Income manager that handles everything with the currency; gaining, spending, tracking

Suspicion manager, etc

Stuff like that. I think I've done a pretty good job keeping them all in their own lane, and since everything is UI based, I think most of the game needs to know about what they're doing, I"m just trying to find a cleaner way of getting the data from each of them

[dusk apex]

You've got a lot of managers. Unless it's multiplayer and you're evaluating the statistics of multiple players, the data could be stored locally on the Players.

[swift falcon]

do all those objects have a single script and need to be inside the same scenes? if so you CAN just slap all the scripts on one manager object at the very least

[burnt echo]

They are all currently on their own scene objects and are single scripts

[dusk apex]

Dependency on third party objects is a boiler plate that I'd avoid unless necessary - ease of access has legitimate uses in game dev but often times is abused.

[burnt echo]

Yea, I mean I still consider myself to be new at game dev. This is my biggest project so far at like 1200 lines, so it's nothing ridiculous, but I want to learn to do it "correctly" and I can already feel that things are getting kind of messy and tangled, so I'm just looking for options, patterns, etc

Everything is working great though, I have no other issues besides a dirty feeling. Lmao

[quaint rock]

just work on a paticular problem at a time

[dusk apex]

Don't want to ruin your fun. Finish it and remake it a dozen times later.

[quaint rock]

games really do not have a overall approach to follow since things differ much more then in other domains of software

and unity makes traditional dependency managment harder

due to not having just 1 entry point and being able to easily pass stuff down via constructors

[dusk apex]

We're just mangling a bunch of callbacks and whatnot together..

[burnt echo]

Alright, that does make me feel better, thanks a lot guys

[quaint rock]

like everything i do at work is really a big pile of different approaches for different problems

[burnt echo]

Yea, I'm a dev for a medical software company, but I'm trying to get more into games and it is a very different beast. Lol

[quaint rock]

also what i do recommend is do not abstract too early

[quaint rock]

oh cool i worked for a medical device company in the past

hi all, I have this weird thing going on with the tilemap as my player chracter collides with another 2d object. Any idea what it is?

[dusk apex]

People likely aren't going to download the mkv file. Try mp4 format or something other that would embed into Discord.

[light beacon]

its like the tile lines are flashing while im colliding with an object

[dusk apex]

Sounds like a perfect pixel issue https://forum.unity.com/threads/flickering-lines-when-my-player-moves.656467/

[mental rover]

you can also try setting your scale to 1 - the editor game window scaling can make things look a bit weird

[dusk apex]

Moving in tiny increments can produce this artifact. There are some work arounds.

Yeah which is the work around that I've been using. Thanks so much for pointing me in a better direction.

... damn, I'm a fucking idiot 😭

[primal wind]

Happens to the best of us

[static lantern]

Run into this issue a couple of times now. Anyone know why, when I serialize data using JsonUtility.ToJson(), it just returns a pair of brackets?

[primal wind]

Because it probably doesn't know what to do

What are you trying to serialize?

JsonUtility is pretty limited

[static lantern]

public struct WorldData
{
    public string name { get; private set; }
    public Dictionary<string, CharacterData> Characters { get; set; }

[Serializable]
public struct CharacterData
{
    public string id { get; private set; }
    public string name { get; private set; }
    public int credits { get; private set; }

    public CharacterData(string id, string name, int credits)
    {
        this.id = id;
        this.name = name;
        this.credits = credits;
    }
}

[primal wind]

It can't handle Dictionaries

[static lantern]

Alright, standby

Commented that out, same results

[primal wind]

It has other limitations

[hexed pecan]

Probably cant serialize a property either

[primal wind]

Let me find them

[hexed pecan]

Does WorldData have the [Serializable] attribute?

[static lantern]

It does, dunno why I didn't grab it with the c&p

[static lantern]

Changed to regular variables, seems to have fixed it:

{"name":"Seb"}

[primal wind]

Uh

[late lion]

JsonUtility has the same limitations as any serialization in Unity, it's all the same serializer behind it. That means no properties, unless you have a [field: SerializeField] attribute on it, and fields must be public or have [SerializeField]

[primal wind]

Honestly i would just use Newtonsoft.Json but that's your choice

[static lantern]

I really should.

[potent sleet]

its ok we should've checked earlier

[static lantern]

Unity really be like "dictionaries who?"

[primal wind]

Yeah it's kinda annoying

[shrewd meteor]

man, thanks so much for helping me for like 2 whole days bro, I really appreciate it, it works just fine now 😭

[potent sleet]

np. glad is workin 🥳

[static lantern]

oh that's hot

{
  "name": "Seb",
  "Characters": {
    "Sebastian": {
      "id": "0",
      "name": "Sebastian",
      "credits": 10000
    }
  }
}

Kind of makes you wonder why Unity even bothered making JsonUtility when they could have just baked in the open source NSJS

[heady iris]

they did use it internally until recently

now it's just an easy-to-install package

https://docs.unity3d.com/Packages/com.unity.nuget.newtonsoft-json@2.0/manual/index.html

notice how it used to say it's "not supported"

[primal wind]

So i wasn't dreaming, it was in the manager at some point

[twin nacelle]

any channel to ask for help or here?

[heady iris]

i presume JsonUtility was slapped together a long time ago

[heady iris]

[late lion]

When CoreCLR arrives, we can use System.Text.Json 🙏

[primal wind]

CoreCLR?

[late lion]

The latest .NET runtime where are the new C# features are being added. Unity is stuck with Mono/.NET Standard 2.1 until they migrate to CoreCLR, which is underway.

[primal wind]

Oh cool

[static lantern]

3.0 is "verified", whatever that means
https://docs.unity3d.com/2019.4/Documentation/Manual/com.unity.nuget.newtonsoft-json.html

[primal wind]

Then maybe I'll get to use System.Random.Shuffle before i become 50

[heady iris]

that means they're reasonably sure it'll work properly in that version of unity

[heady iris]

huh, that exists?

neat

i've written the fisher-yates shuffle a few timse now lol

[primal wind]

Yeah .NET 8

[static lantern]

Blackbox it for later, don't make yourself rewrite that over and over

[heady iris]

it goes in an extension method :p

but yes, I think i'll just be using the shuffle method now

[static lantern]

Watch the shuffle be the same algo

[heady iris]

it probably is

the only drawback is that this isn't using UnityEngine.Random

which cooooould be relevant for seeded stuff

but, not really: you'd already have a separate RNG for the shuffling

it's a wash

[static lantern]

Well this is an odd example to use. From Wikipedia:

It reminded me of it

i haven't touched that in a while. i am recovering.

It's not my job so i guess it helps not becoming crazy

[static lantern]

Oh look at you, knowing how to maintain healthy seratonin levels, good job!

[primal wind]

I wanted to make a website for my stuff and a friend recommended Svelte which seemed so much easier and friendly that every other popular option

React still gives me nightmares

[heady iris]

huge upgrade from js

i can at least understand what my old ts code does

[dusky lake]

Oh react is easy... its just like html, right... right?

[heady iris]

static type checking is such a godsend

it's why C# doesn't make me sad (too much)

[static lantern]

Would be nice if browsers natively supported TS but, eh.. what can you do?

[dusky lake]

Hey my first job was vanilla js + jquery, so I know the pain 😄

[primal wind]

If i could make everything with C# i would

[heady iris]

i have some old js-only web "applications" (scare quotes mandatory)

You can already use it

It's just very shitty to set up

Something about setting up the linker for it to work properly

So totally not worth it

[heady iris]

don't be a coward. just serialize data via memcpy.

[thin aurora]

Just ToString() your class and store that instead

Why so complicated

[static lantern]

Yeah? Now reverse it

[heady iris]

wait, isn't that basically a save-state

Wait, I don't know shit, is it really that easy to dump memory in Linux?

[thin aurora]

Damn it didn't work, you're smart

[static lantern]

Skill issue.

[heady iris]

it lets you directly read and poke any physical memory address https://man7.org/linux/man-pages/man4/mem.4.html

Huh

TIL

[heady iris]

but anyway, unity,

[static lantern]

yes, unity

quality product

no problems

10/10

[heady iris]

it hasn't randomly frozen on me in a while on my macbook

[primal wind]

Unity is great but the issues can't be ignored eternally

[heady iris]

they also fixed the random SRP crash

very nice

[static lantern]

Unity: "I'll fucken do it again"

[primal wind]

Uh

I legit never got a crash that wasn't my fault so i guess I'm lucky

I'm really interested in how Minecraft shaders work cause i would really like to make something like them in Unity. They should be lighter than regular realtime lights

I'll have to poke around one

[static lantern]

Try telling a struct it can be null and enjoy Unity never not crashing

[primal wind]

Even if I'm a beginner at shaders

Oh

[static lantern]

Have a friend in college learning shaders.

He ELI5, but made it clear it can get very deep and encouraged me to learn Algebra from scratch

[heady iris]

shaders are cool

[primal wind]

I'm not that great at maths

[static lantern]

Since, when I was in high school, I ignored algebra like my mother ignored my father's alchoholism

[heady iris]

i need to learn more about writing shaders that are more physically realistic

i mostly just write stuff for special effects

[static lantern]

Honestly these are more fun than photorealistic shaders.

I think the pursuit of perfect photorealism is a bit.. toxic?

[heady iris]

i do want to make some toon-y stuff

or maybe stealing some visual cues from Hi-Fi Rush

i love stealing visual cues

[primal wind]

Some games make realism their main point and forget about gameplay

Is it a game if it's not fun to play?

[heady iris]

i saw a tutorial for re-creating its Ben-Day dot bloom effect

[static lantern]

Like, go look at the CryEngine tech demo. They focus entirely on graphics. To be fair, that's their whole claim to fame, but there's almost nothing being shown off on the technical side. Oh, you can do ragdoll IK? Mkay.

hello. so i made climbing scripts for a VR game with gorilla locomotion and i currently have 2 problems.
the 1 one is that if i grab onto something my player is glitching weird (yes the rigidbody is kinematic) and the 2. problem is that if i grab onto a swinging object im not moving with it. i will send a video of how it looks like. appreciate any help.

[static lantern]

THERE IT IS

[heady iris]

jitter like that makes me think that some stuff is happening in fixedupdate and some stuff isn't

is interpolation enabled for the rigidbody?

[rancid basin]

i can send the scripts wait

[heady iris]

i'm not sure how that'd interact with VR

[heady iris]

i've only done like one game jam involving VR lol

[rancid basin]

these 3 scripts are handling the climbing. it may could be the problem of the gorilla locomotion

[static lantern]

damn, called it

[primal wind]

I would make VR games and mod existing games into VR if i had a headset

[rancid basin]

i already fixed some of the lag by putting the "Delta = lastposition - transform.position" in update. it was in lateupdate before

[heady iris]

late update takes place after animation

i wouldn't expect that to matter otherwise

[lean sail]

Late update is typically just for camera movement

I don't really get what you're doing with the fixed update last = transform.position,
Is your delta value anything other than 0?

It seems like if it is, its gonna be very unreliable to move the player consistently

[rancid basin]

the delta value is my hands position - position

[lean sail]

I see that, but is your delta value working for each frame?

I cant imagine that it does

Plus in your Move() you are multiplying by fixedDeltaTime which is just 1/50

But it's still being called in update

Hey guys and gals. So when I shoot at an enemy, the missile hits the target and the explosion which is in a gameobject container works. But, it is not destroying the effect or the light. Here is the code ```using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MissileController : MonoBehaviour
{
public float missileSpeed = 30f;
public Rigidbody rb;
public GameObject hitParticlePrefab;

void Start()
{
    rb = GetComponent<Rigidbody>();
}

// Update is called once per frame
void Update()
{
    rb.AddForce(transform.up * missileSpeed);
}

private void OnTriggerEnter(Collider other)
{        
    Instantiate(hitParticlePrefab, transform.position, Quaternion.identity);
    Destroy(gameObject, 1.0f);          
}

}``` Is it because the effect is contained in a gameobject as a child and I have to delete the children? Thank you in advance for pointers please.

[prime sinew]

which line of code destroys the effect or light

[remote abyss]

@prime sinew I thought once you destroy the main gameobject the effect's are children off they should all be destroyed?

[prime sinew]

show the hierarchy? what's supposed to be destroyed?

[fluid tapir]

Hey guys, I am trying to implement layered animations in my animator using Animation masks. I am trying to create a combination of rifle put away and walk/run animations. For example, we can draw the rifle while walking or running. What I've done is:

1. Base Layer: Consists of the idle/walk/run blend trees (for both with rifle and without rifle)
2. Hand Layer: Consists of the mask for only hands and the animation where the player draws / puts back the rifle.

The issue that I am facing here is that when the animation for putting away the rifle finishes the hands of the character stay still for the animation it played using the Hand Layer. Is there any way to fix this ?

[remote abyss]

@prime sinew

the code is on the Explosion3 object

[lean sail]

What's the hierarchy after the parent is destroyed?

[fluid tapir]

while moving (I have connected the rifle put away to exit and it is looping)

However when I remove the connection with "Exit" state in the state machine this is the result (Second image):

[prime sinew]

not sure, this seems right. you can try to deactivate the children before destroying the parent though

https://www.reddit.com/r/Unity3D/comments/2kfzzx/comment/clkyshp/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

[lean sail]

U shouldnt really have to. The children should get destroyed

We should look into why instead of hacky work arounds for something that should work

[remote abyss]

thats what I thought

[lean sail]

Show the hierarchy after its destroyed

I believe it might be related to the instantiate but not too sure

[remote abyss]

@lean sail can you elaborate not sure I follow you on "show the hierarchy after its destroyed" pls.

[lean sail]

U showed the hierarchy, show it again after destroy() is called

[remote abyss]

ahh ok

@lean sail hrm...

[lean sail]

Is your script on the right object

[remote abyss]

so it does destroy the explosion but not the main gameobject and other children. Script is on the main object the container Explosion3

[lean sail]

What is hitParticlePrefab

[remote abyss]

sorry the script is on the missile not the explosion3 my misstake

hitParticlePrefab is the explosion prefab

[lean sail]

ah i guess u have your solution then

[remote abyss]

ahh I see what I did wrong. Im destroying the hitparticleprefab from the instantiated missile prefab .

[lean sail]

Well idk which object is which unless u show the prefab, your script is just on the wrong object

Or you intend to call destroy on the parent

Hey guys. Something weird is happening in my Unity. Before I used to build apk for my game and test them out. I saw the option for patching so i pressed Patch. But it crashed my PC. So, I got back to just Building the apk. But now the Build process crashes my PC after 20 mins. It never took that long to build either. Please help. Its really urgent.

[remote abyss]

Yupp fixed it. Put a destroy(this.gameobject, 2.0f); on the explosion prefab and that solved the issue. hehe thx guys!

[rancid basin]

i also had similar issues before. try using a different unity version. if you use 2021.3.1f use 2021.4 or .3.2f like use a similar version

ok. im using 2021.3.9f1

disable the hand layer if your not using it

do that by changing its weight to 0

Guys, I need your help,
I need to make the following code clamp between -90 and 0 degrees on the x but I cant help it

  private void FixedUpdate()
  {
    float angleY = 0;
    float angleX = 0;

    if (turning)
    {
      // Calculate the rotation angle and direction
      angleY = turnSpeed * Time.fixedDeltaTime * (turnRight ? 1f : -1f);
    }

    if (_tilting)
    {
      // Calculate the rotation angle and direction
      angleX = tiltSpeed * Time.fixedDeltaTime * (_tiltUp ? 1f : -1f);
    }
    // Apply the rotation on global axes
    transform.eulerAngles = new Vector3(transform.eulerAngles.x + angleX, transform.eulerAngles.y + angleY, transform.eulerAngles.z);
    
  }

Any implementation with Quaternions or something?
Whenever I use them z-axes gets disruppted as well!

[fluid tapir]

I kind of found a work around for that was to transition to an empty state for that layer after the draw animation is finished. I did think of resetting the weight of the layer to 0 but that will be too much code. Thanks anyways for your help 😄

did it work?

Hey all, I am attempting to use fishnet and XR Interactions toolkit, I am needing to change XR Interactions Toolkit scripts from Monobehaviors to NetworkBehaviors, however in any of the XR Interactions scripts, I am unable to use "using Fishnet.Object", and thus cannot change the script from monobehavior to NetworkBehavior. Any leads on what might be going on here? Is it something with the default assembly?

Xr Interactions toolkit scripts are in their own namespace, if that helps.

[smoky sonnet]

I'm moving my question here from #💻┃code-beginner :

I have a building system that allows you to freely place objects, and rn Im trying to make the colliders work. The issue is that the preview is always red (meaning it's colliding). The terrain has the Ground tag (which is layer 9) and the placeable objects have the Building tag. ```csharp

    if (Physics.CheckBox(_objToPosition.transform.position, bounds, Quaternion.FromToRotation(Vector3.up, hitInfo.normal), ~(1 << LayerMask.NameToLayer("Ground"))))
    {
        // Collides
        _objToPosition.GetComponent<Renderer>().material = _buildingMatNegative;
        return;
    }``` 

Somehow the above if statement still executes true even though the object to position is only hitting the terrain and nothing else.

I've been stuck with this a few hours now and it's driving me crazy

I've tried a lot of different things but none worked

The cube does have a collider

I have this piece of code which basically implements a grid but sometimes I have problems with removing an element from it.
You can see the debug and condition for it in the Remove method.
This is a typical debug message (almost always the same with exception of position) asd 0, 0, contains: False, wp: (-1.16, 0.00, 1.35), sameList: True, removed: False everRemoved: True, sometimes 0, 0 is something like 2,2
Next there goes ArgumentOutOfRangeException at the line with list.RemoveAt

I don't understand how I use it though

[somber nacelle]

did you read the Usage section of the readme?

[fast aurora]

well yes, but it doesn't say much on how to use the BoxCast

Do I replace the existing raycast?

[somber nacelle]

You can replace calls to Physics and Physics2D methods with DrawPhysics and DrawPhysics2D to simply draw the results of a physics operation.

[languid hound]

Just hypothetically is there a way to detect input via script with the new input system? Like no bindings just like DetectInput GenericGamepad/Whateveryayayawdhiaduawidh?

[somber nacelle]

yes, check the docs in #🖱️┃input-system

[languid hound]

Oh hell yeah! Thanks

I don't know why I didn't think of looking at the docs

[somber nacelle]

oh also, if you want it to be easier, you could use the using alias suggested in the Code stripping section of that same Usage description. This is what I typically do so I don't have to worry about remembering to use DrawPhysics2D instead of Physics2D when using multiple queries in the same class

[round palm]

Hey guys, I need help with something. In my game the camera follows the player by having the exact x and y position as the player every frame, so no lagging behind and catching up. I want the camera to cut off at a certain part of the room (which I have done) and only allow the player to move (with the camera) to the rest of the room after the player has touched a certain object. However, if I immediately set the camera position to the player position once the player touches the object, it will be a hard cut and be jarring. Rather, I want to animate the camera to return to the player, then to resume its previous movement of matching the player's position. I am trying Vector3.Slerp for the animation, but I can't seem to get any code to work. Ideas?

[hidden compass]

Cinemachine

it does that for u automatically

[round palm]

how do I implement that

[hidden compass]

when u disable one VirtualCamera, and enable another, it'll smoothly translate

if u dont want to use cinemachine u can Lerp the camera to the new position

[hidden compass]

its pretty simple

in the package manager you can install Cinemachine...

its a unity package..

and then use 1 camera

have it whereever u want it.. and create 2 virtual camera's

[round palm]

thanks

[hidden compass]

when u wnt it to be stationary.. u switch to the VCAM without the follow code

and then disable it and enable the camera WITH the follow code

it'll automatically transition

[atomic matrix]

why is my visual studio white and errors dont have the red underline and there is no minimize or maximize buttons in top right?

[heady iris]

visual studio machine broke

that is an interesting graphical problem

i'd restart your computer first

[atomic matrix]

this happened like a week ago ive just been trying to deal with it

[hidden compass]

@round palm or u can change the PRIORITY of the virtual camera

and the one with the higher priority will be the one it transitions to.. u can see here the camera im messing with is just there.. the other camera is attached to the player controller..

not even needing to mess with that one..

what it does is.. the virtual camera acts as a place holder.. for where the main camera is positioned

main camera just gets the cinemachine brain component

[round palm]

cool

I really appreciate the explanation

As for the "no underlines", your projects are unloaded (see the Solution Explorer tab). Right-click them and select "Reload with dependencies" to fix

[edgy lynx]

I inspected the code for the Unity player controllers from their HDRP sample scene, and saw they had something of the sort like:

            InputAction receivedInputAction = (InputAction)obj;
            InputDevice lastDevice = receivedInputAction.activeControl.device;
            _isKeyboardAndMouse = lastDevice.name.Equals("Keyboard") || lastDevice.name.Equals("Mouse");

Which I just made into an event:

    private void InputActionChangeCallback(object obj, InputActionChange change)
    {
        if (change == InputActionChange.ActionPerformed)
        {
            InputAction receivedInputAction = (InputAction)obj;
            InputDevice lastDevice = receivedInputAction.activeControl.device;
            _isKeyboardAndMouse = lastDevice.name.Equals("Keyboard") || lastDevice.name.Equals("Mouse");
        }
    }

Is there a smart way to spawn in a clone but as a child for the Parent?

[simple egret]

Some overloads of Instantiate take a Transform as last argument, the Transform it will be parented to.

I'll look into it, thanks

Hi! I'm making a classic card game, is it worth making each card an ScriptableObject? or just a class and generate the deck is enough?

[willow hull]

Quick Question : is it a bad idea to send from the server a json which inside include the list of all the characters of the player and their stats to the client? using tcp

[somber nacelle]

classic card game as in regular playing cards (52 card deck with suits, royals, and numbers)? if so, don't bother making every card a scriptable object, that's certainly overkill. An enum for the suits then either an enum or just straight numbers for the cards would be enough, then making the deck is as simple as a couple of for loops

That's what I thought, thanks

But I get:

IndexOutOfRangeException: Index 65 is out of restricted IJobParallelFor range [21...21] in ReadWriteBuffer.

How should I solve it?
I noticed that a simple nativeArray.AsSpan() disables the Unity safety checkings... should I do that?

Quick Question: how do I set up a check to see if an object is on another object, like a box on a button, to play an animation?

[leaden ice]

"if an object is on another object" what do you mean exactly?

[heady iris]

like, a collision?

[leaden ice]

like a crate touching a physical button, portal style?

[steel bronze]

ya, similar

[leaden ice]

I did the buttons in this video using a trigger collider and an animation:
https://www.youtube.com/watch?v=Tcf6Kafs4Ro

basically an object sitting on top will trigger the trigger collider causing the animator to depress the button

and vice versa

[steel bronze]

ya. i'm trying to do something like that, just not as a drone

[leaden ice]

Yep the drone obviously isn't relevant was just giving the video due to my button

I have a 2d character I'm working with, when it was set up it was only given 1 large collision box that was used for both hit-scanning and for world movement collision. I'm assuming it was set up that way because collision boxes are components in unity and a script can really only address one collision box at a time.

I'm wondering what would be the best way to go about setting up several collision boxes like I've drawn. I've done this before in another engine, but there collision boxes were objects not components so it was fairly straightforward to pull all of them into one script.

when a collision event occurs, all components with the appropriately named methods will get that method called

i'd just put them on different objects, and put components on those objects to handle the events

[glad sentinel]

Okay so peep this: I want to make a bestiary in my game but I'm not super sure of the best way to go about it.

Essentially it'd be a book that would slowly fill over time as you meet new creatures, obviously the UI would be a different matter, I'm just not sure of how I would get this done - or am I just looking too deep into it and would it just be a case of a LOT of triggers?

I have a decent idea of what I want, I just need to iron some stuff out

[carmine cloud]

so I'd probably need multiple layers since the hit box and movement box would both be looking for OnCollisionEnter2D ?

[heady iris]

yes, you should separate them out by layer

this also requires that they are on separate objects

[heady iris]

you could have a list of every enemy type you've found

i'd start with just displaying all of the enemies

figure out that interface first

then worry about hiding ones you haven't found yet

[carmine cloud]

for the separate objects I should just use empty objects nested inside my character?

[heady iris]

ye

you might have several hitbox objects parented to different things

[carmine cloud]

besides what Chemicalcrux said, you need to also figure out what your learning condition is. Is it just them appearing on screen? Do they have to get into combat with them? do they have to kill them? this condition will determine what mechanics you need to implement to trigger an update in your bestiary.

just seeing them could be a ray cast or a really large trigger collider, combat could be registering a hit or damage on them, death could be interacting with a trigger collider that's enabled on their corpse, there are tons of different approaches.

[glad sentinel]

Bet, thank you kindly

[steady moat]

You always want to sperate the Collision (Movement) and the Hitbox. Those operate on two different worlds and do not have the same layer most of the time. It is a good practice for performance, design and maintainability.

[carmine cloud]

yea I wasn't the one who set up the character initially, I'm just trying to fix it now. I've done the above set up in a different engine I just wasn't sure how to go about it in unity since colliders are components. but yea basically I was overthinking the component thing.

[fiery jackal]

Hey everyone, I have a question about the CombineMeshes. I combined a few hexagon planes, it created a single mesh, but it still behaves as if each of the hexagon is a separated object when I apply my Shader that moves the normals. Shouldn't it merge the common vertices into one?

[topaz ocean]

is there a practical means to destroy all components on a gameobject except the transform with consideration for requiredcomponents?

[steady moat]

This is expected, combine mesh does not remove triangle and vertices. This function is used for manually batch together meshes to reduce the number of draw calls.

What you are looking for is the concept of boolean operation (Union in your case). Something like: https://docs.blender.org/manual/en/latest/modeling/modifiers/generate/booleans.html

[steady moat]

No, there is not. You need to iterate on every component and do the appropriate validation before deleting it. If this something that you are doing in runtime, you might want to find an alternate solution as it is not something that is efficient to do.

[fiery jackal]

Can I achieve that through code in Unity?

[topaz ocean]

I suppose I could just reverse the array of components when clearing them. As long as I only add dependent components so that their dependency is automatically added this should work without issue.

Seems to work, and I can only see this failing if unity changes the order in which dependencies are added to an object.

[steady moat]

You should not depend on that. You can use Reflection to find RequireComponent attribut.

[topaz ocean]

what is that

Hey guys.

Im doing a jump system and a horizontal move using mobile rotation.

Jump works by clicking once or clicking and hold to jump higher.

When i created the horizontal function the jump holding is not working anymore.

Flux:

        private void Update()
        {
            if (!isAlive)
                return;
            this.playerJumpInput = Input.GetKey(KeyCode.Space) || Input.GetMouseButton(0);
            this.playerJumpInputUp = Input.GetKeyUp(KeyCode.Space) || Input.GetMouseButtonUp(0);
            this.playerJumpInputDown = Input.GetKeyDown(KeyCode.Space) || Input.GetMouseButtonDown(0);
            if (this.playerJumpInputDown && (IsAnimatorReady() || isSwinging)) isGoingToJump = true; // Jump from ground or vine
            isFalling = (this.playerRigidbody.velocity.y < -0.1f) ? true : false;
            if (this.playerRigidbody.velocity.y < -10) isRolling = true;
            AnimatorHandler();
        }

        private void FixedUpdate()
        {
            if (!isAlive)
                return;
            if (!isSwinging)
            {
                this.MovePlayer();
            }
            else transform.position = currentVine.transform.GetChild(0).position;
            if (this.isGoingToJump && this.IsPlayerGrounded()) this.Jump();
            if (this.isGoingToJump && isSwinging) this.JumpFromVine();
            if (this.playerJumpInput && isJumping) this.JumpHigher();
            if (this.playerJumpInputUp) this.StopJump();
            if (isJumping && this.playerRigidbody.velocity.y < 0f && this.IsPlayerGrounded()) isJumping = false;
            HorizontalMove();
        }

Jump Code:

        private void Jump()
        {
            Debug.Log("Start Jumping");
            isGoingToJump = false;
            this.playerRigidbody.AddForce(Vector3.up * this.jumpForce, ForceMode.Impulse);
            isJumping = true;
            isRolling = false;
            jumpTimeCounter = jumpTime;
        }

Horizontal move:

        private void HorizontalMove()
        {
            var dirZ = Input.acceleration.x * 20f * -1;

            float speed = Mathf.Clamp(dirZ, -20.0f, 20.0f);
            Vector3 vel = new Vector3(this.playerRigidbody.velocity.x, this.playerRigidbody.velocity.y, speed);

            Debug.Log("vel: " + vel);
            this.playerRigidbody.velocity = vel;
        }

So i think the problem is that im using add force to jump

[somber nacelle]

it's cs to format for c# syntax highlighting. also use a bin site to share large blocks of code

[limpid siren]

and when i do the horizontal move and set the velocity of y it stops the impulse

[limpid siren]

thnks

How to fix :(

Nvm, the fix was to move it to the Editor folder, it worked!

[rancid pollen]

hi, might be a silly question, but i'm just wondering if there's an efficiency difference (or at least a preference) between

class A
{
    B b;    // assume no nullref    
    void Method()
    {
        StartCoroutine(b.DoSomething());
    }
}

and

class A
{
    B b;  
    void Method()
    {
        b.StartCoroutine(b.DoSomething());
    }
}

[orchid bane]

When I try to install my project as apk on Bluestacks it says the version is inappropriate even though it was fine before. I switched to IL2CPP. Any ideas?

[lean sail]

there shouldnt be a difference in efficiency, all you would be doing is starting the coroutine on object b instead of a. Only really matters if u disable object A or B

[woeful slate]

I have a 2D top down game. I'm using TileGrid (so many layers ) to create the landscape, but I want to allow the character to use a shovel to expose dirt, and then expose a hole sprite. Would that mean every tile needs to be a game object?

[cosmic rain]

No, but you'll need to change the tile dynamically. Look up scriptable tiles in unity.

[woeful slate]

Thanks! I'll look into these

[orchid bane]

Is burstCompile useful to put on functions which aren't jobs?

[cosmic rain]

In rare cases. If the function satisfies the burst compiler requirements. There's no guarantee you'll get any significant performance improvement from that though. The point of burst is that it makes use of SIMD feature of the CPU.

[orchid bane]

There aren't any collections in my function

But there are only structs

What do you think?

[cosmic rain]

I mean, you can try and see for yourself.🤷‍♂️

[orchid bane]

Doesn't hurt I guess

[visual fractal]

Sorry about the delay. https://paste.ofcode.org/XTa6z7UGuipKmXcsWncJjd

I got this code off the Unity Marketplace.

It's the Modular First Person pack, so the code should be working. Could it be because I'm in a newer version of Unity?

[cursive moth]

I don't think that's the case, did you setup the inspector values properly?

[visual fractal]

I think so.

Let me check.

[cursive moth]

code does indeed seem fine but I am quite tired so chances are I am missing something

[visual fractal]

Inspector seems fine. If you're tired, then I'll stop bothering you if you want.

[cursive moth]

nah you are not bothering me

I am just saying that there is a chance I'll miss something crucial

did you setup the object as the creator of the asset intended?

and also, are you getting any errors in the console?

[visual fractal]

I used the player object that was provided in the pack, and the error is NullReferenceException: Object reference not set to an instance of an object FirstPersonController.FixedUpdate () (at Assets/ModularFirstPersonController/FirstPersonController/FirstPersonController.cs:425)

I don't see anything wrong with line 425 in the script, though.

[cosmic rain]

There doesn't have to be anything wrong with the line. It simply tries to access null.

[visual fractal]

It's just something to do with the sprint bar that I have disabled.

[cosmic rain]

Debug the references on that line to find out which one is null.

[cursive moth]

Chances are the script requires that very sprint bar and it doesn't execute the rest of the function after that error

yeap

remove that line

I mean those lines

[cosmic rain]

Honestly, if you're asking in #archived-code-general, you're expected to be able to debug the code.

[visual fractal]

It shouldn't make it not work, though.

I'll try.

[cursive moth]

go through the code and see if the sprint bar appears anywhere else

[cursive moth]

well you are fixing the error that's preventing the rest of the function to execute so it should work

[cosmic rain]

Errors stop execution of the rest of the function, so they should never be ignored.

[visual fractal]

Now there's this error. Assets\ModularFirstPersonController\FirstPersonController\FirstPersonController.cs(520,1): error CS1022: Type or namespace definition, or end-of-file expected. There is absolutely nothing wrong with line 520. It's just a }

[cosmic rain]

You've probably deleted/commented out a brace or something...

Or added one extra

[visual fractal]

It's the end of the script, though. Should there be anything other than a squiggly bracket?

[cosmic rain]

The compiler counted the opening and closing brackets in the script and found out that there's one extra(or missing). It doesn't have a way to know which one it is(since that depends on the logic in your code), so it points to the last bracket.

Although that's just an assumption. It could be some other syntax error. Impossible to tell without seeing your code...

[visual fractal]

Ok, I fixed every error except one, and I don't understand it. Assets\ModularFirstPersonController\FirstPersonController\FirstPersonController.cs(436,5): error CS8803: Top-level statements must precede namespace and type declarations.

This is the line of code it's talking about: void CheckGround()

[woeful slate]

do you have a good recent resource for this? all the videos I find are multi-year old

[cosmic rain]

The unity manual.

[wide terrace]

It sounds like some code appears to be somewhere it does not belong. Code outside of a class or method which should be inside a class or method body, among other things. Could just be an extra or misplaced closing bracket. Your IDE should provide some highlighting and insight into the problem?

[visual fractal]

I don't think there are any misplaced brackets, and this void is in the same place relative to the rest as all the other voids. ```void CheckGround()
{
Vector3 origin = new Vector3(transform.position.x, transform.position.y - (transform.localScale.y * .5f), transform.position.z);
Vector3 direction = transform.TransformDirection(Vector3.down);
float distance = .75f;

    if (Physics.Raycast(origin, direction, out RaycastHit hit, distance))
    {
        Debug.DrawRay(origin, direction * distance, Color.red);
        isGrounded = true;
    }
    else
    {
        isGrounded = false;
    }
}```?

[cosmic rain]

Share the whole script.

[lean sail]

also show where your IDE underlines an error

[limpid siren]

can anyone help me here?

[visual fractal]

https://paste.ofcode.org/iPgZ66uJWkUd7u6qdJbRC3

[wide terrace]

There's an extra closing bracket in the method above CheckGround(), which results in the previous method and class body closing early. The compiler thinks void CheckGround() is outside of the class, because it is

[visual fractal]

Ah.

Thanks.

[lean sail]

your code is hard to read on discord, but you should add debugs to see what input exists at once. Like if your jump holding gets canceled by pressing horizontal movement. I dont see any specific issue with your HorizontalMove

also pls format your code to be more readable, it may seem concise to you for anyone else its difficult to read

[lean sail]

also just nitpicking, but this ternary doesnt need to exist
isFalling = (this.playerRigidbody.velocity.y < -0.1f) ? true : false;
the boolean expression
(this.playerRigidbody.velocity.y < -0.1f)
already returns true or false

[limpid siren]

i fixed it hardcoding a instant velocity when jumping instead of just waiting for the impulse force eheh

now im dealing with a situation

why velocity got stoped everytime it is colliding with a wall?

or any other object

i want it to keep falling, even if it is colliding with a wall

i just want it not to go trough the wall

[lean sail]

do u have a physics material on your collider? i assume this is because of the friction

[limpid siren]

no

[lean sail]

if you want it to slide off the wall then u need a frictionless material

u can create a physics material and just set it to 0 then put it on the colliders

[limpid siren]

perfect bro

[indigo haven]

Hey good day.
I have a dijkstra matrix (chess board with numbers representing distance from a point to that square) and i wanted to make a color gradient using that info, is there any way of doing so without needing materials for each distance nor shaders?

[mental rover]

have a look into https://docs.unity3d.com/ScriptReference/MaterialPropertyBlock.html

iirc there's a problem with it in that you can't batch materials if you use it, which sort of defeats the entire point of the optimisation, so perhaps there's something better out there

[indigo haven]

I will, thanks. And dont worry i dont care to much about optimization for now

Hello good day, I have a game which has multiplayer in it using Netcode for GameObjects. I used to make the server build and the client build from the same project. This used to work when the project initially had no other third party plugins but I went ahead and added mediation and what not to the project, without thinking about how it could effect the server build. Now, I am unable to make a server build specifically a linux server build since plugins like AppLovin (an adk sdk) don't support these platforms. How do I salvage the project now? Also, how do you guys handle server/client architectures and third party plugins? Thank you for your input

I keep getting MOVING FILE FAILED - access denied errors when I attempt to open my unity project after a format. 5 years of work gone? Have rebuilt temp/library folders still same

[thin aurora]

5 Years of work gone? Are you not using source control?

[simple egret]

What do you mean by "after a format"?
Just pull the latest version from Git. If you haven't made backups in 5 years then that's on you

[severe maple]

I have the latest backup. I had to reinstall windows on a new drive, along with unity and hub. Tried to load my project (different HD) and get errors as above

[simple egret]

Unity may not have sufficient rights to move files. Try running it as administrator and see if that fixes the issue. Also check your Hub configuration, it might be trying to move files from folders that don't exist anymore
