alright, appreciate it

[warm badger]

hi, suppose i have a list and i want to remove some specific elements by index(such as index 1,3,4 etc) from the list, what should i do? a for loop return error in this case

[mellow sigil]

https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.list-1.removeat

and if you need to remove more than one remember to do it in reverse order starting from the highest index

[warm badger]

thank you

Hey all, having a weird issue with serializing to file. I've created a really simplified code snippet and it even failed with the message: UnauthorizedAccessException: Access to the path is denied. I googled it and it said it could be an issue with my Windows permissions so I did a complete reset and the problem still persists. I've put all the 3 code files into a codeshare, any help appreciated! https://codeshare.io/g8Pp6V

[knotty sun]

you are supplying a path but no file name

[stable geyser]

omg what a stupid mistake to make

ty 😛

[cosmic fjord]

guys my (gamecanva) does not show the elements inside it (it was fine) any one has similar issue

when i click on the canva it show me where the camera is

[knotty sun]

which gameobject contains that border image?

[cosmic fjord]

background canvas

[knotty sun]

so you have 2 canvas's active at the same time?

[cosmic fjord]

yes

one for background and the other 3 canvas one of them will be active depend on the situation

[knotty sun]

you should use Panels for that, not seperate canvas's

[cosmic fjord]

panels
let me read about it then

[cosmic fjord]

so each panel can have is it buttons images
and from the script i can show and hide another right?

[knotty sun]

correct

[cosmic fjord]

that is strange so when we use multiple canvas?

[knotty sun]

when you use world space canvas's

[cosmic fjord]

huh
do you have examples of that

or you can explain it in more details if you don't mind

[knotty sun]

say you have 2 characters in the scene and each has it's own dialog or stats canvas. Then you would make a world space canvas for each character

[cosmic fjord]

you mean like split screen
so each screen is a canva?

[snow siren]

can i ask a question here?

[knotty sun]

no, a world space canvas exists in the world, not in the screen. So it can be any size and anywhere

[knotty sun]

I have a problem in Unity where my BalanceUI script is not being found in my ScoreManager script. I'm using FindObjectOfType<BalanceUI>() to locate the BalanceUI object, but it's returning null. Any suggestions would be greatly appreciated!

[knotty sun]

And where do you use BalanceUI there?

[trim schooner]

1- the code you've provided (as Steve says) doesn't mention BalanceUI at all
2- if FindObjectOfType<BalanceUI>() is null, then the object isn't being found in the scene -> either you've not got one in the scene, or it is inactive

[snow siren]

so i meant CashUI not balance mybad

yes it is inactive, but the code worked fine for my playerStats and it is also inactive

thats my code for playerstatsText

[knotty sun]

read the docs. There is an option to include inactive objects

[snow siren]

im sorry its my first game, so im a beginner

[knotty sun]

then you should spend more time reading the docs not less

[snow siren]

but im curious why does it work fine with my PlayerStats?

[knotty sun]

what object is PlayerStats on? Player?

[snow siren]

no the script is on the inactive PlayerStatsText its just to display the current stats of the player

[knotty sun]

then you probably have duplicates in your scene so you should debug which PlayerStats has been found

[trim schooner]

this isn't showing the same situation as CashUI.

That GetComponent<TMP_Text>() is called on Awake().. which is called after you make this object active.

[snow siren]

ahh

[knotty sun]

yeah, where is the FindObjectOfType<PlayerStats> ?

[snow siren]

in my PlayerMovement Script and PlayerShooting Script, where i declare the speed and firerate

[knotty sun]

And which object are those scripts on

[snow siren]

ahh maybe i know the problem now

Could the problem be that I am trying to continuously update my balance, which is inactive? Would it be possible to synchronize the score with the balance when I press P and open my upgrade panel?

i solved the problem, thank u !

[knotty sun]

you really need to look at your use of Find and Get because I'm sure that 99% of them are not needed

[iron phoenix]

Maybe I should post this in another thread?
I'm trying to debug a Behavior Subgraph. I can select the Behavior Agent to debug in the main Behavior Graph, and that works fine. It shows that the main graph is currently inside the subgraph, but debugging doesn't show any activity inside the subgraph, and I can't select any agents there for debugging.

If I add another Behavior Agent script to the GameObject and attach the subgraph directly, I can enable debugging on that agent, and it works. However, it doesn't seem correct to use multiple Behavior Agent scripts on a single GameObject.

How can I properly debug a subgraph? Or is it correct to use multiple Behavior Agent scripts if you use multiple Behavior Graphs?

[prime lintel]

Anyone has experience with using Aron Granberg's A* Pathfinding package? I am wondering if anyone got a similar issue as me before where .reachedDestination seems to always be false despite being at the destination transform

[knotty sun]

we do not supply support for 3rd party assets. Contact the publisher

[prime lintel]

I understand that its not directly Unity related and hence isn't something people are to help out with but I was hoping someone had a similar experience and knows what's wrong because the official Discord for the 3rd Party Package does not really help me out

Just hoping someone happened to have a similar issue and know why it is so

[wicked scroll]

have you read this? https://arongranberg.com/astar/docs/iastarai.html#reachedDestination

[whole crystal]

I'm making a fighting game in Unity and I'm working on the input buffer for it. With this I can dynamically create new special moves and perform them, and also images corresponding to button presses show up on screen for a more visual representation. Everything's working correctly so far except diagonals inputs don't read at all as there are images for when you input diagonals like down-left and down-right etc so that i can do proper motion inputs. I added a debug log to check whether it is actually being processed an no nothing's happening at all. Here's the script: https://pastebin.com/fqj0NYCu

HandleInput() is working correctly but HandleDiagonalInput() isn't working at all

[prime lintel]

yep

[worn flare]

yeah its quite tricky

[ashen bough]

How i can get an LocalizedAsset in a Specific Locale?

[steep saddle]

Any idea why the ability to rename an object in the hierarchy by double clicking might have gotten disabled? Not sure what I changed, if anything. Right clicking and selecting rename works.

[leaden ice]

it was never double click AFAIK It's click and wait

After it is selected

So yes two clicks are needed:

• Click once to select
• Click again and don't move your mouse for a second

[steep saddle]

....huh. Yeah that's working. I've been in Unity every day for the last year and for some reason it has felt different the last couple days. Like double clicking quickly used to be more responsive for me.

[leaden ice]

not sure 🤔

[real gulch]

Hey, is this the right channel to post a question about ball physics?

[somber nacelle]

#🔎┃find-a-channel

[real gulch]

@somber nacelle ❤️

@somber nacelle Found the physics channel, hopefully I can figure out my friction issue 😄

[low pecan]

I want to use the OnCollisionEnter2D function to call a function when two objects with the same script touch but i cannot figure out how to get it to not call the function twice

[somber nacelle]

a common solution for that is just comparing their instance id and calling the method only on the higher or lower one (it doesn't really matter which you choose)

[dusky perch]

So I have errors that are leaving me confused. Is this the best place to ask for help?\

[simple egret]

Given that the common point between the two errors is that you're accesing stuff on Camera.main, looks like Camera.main does not have a value (it is null), which means you don't have a camera object with the "Main Camera" tag in the scene

Trying to access anything on a null-reference like you have now will throw that NullReferenceException you're seeing here in the console.

More info on NREs see https://unity.huh.how/runtime-exceptions/nullreferenceexception

[dusky perch]

Thank you. I finally fixed it

[spare dome]

would anyone know how to use singletons and singleton references? I heard they can be good for certain applications such as referencing certain objects you would use a find method for?

I would love to learn how to use them

[somber nacelle]

here's some info about the pattern and its usages, as well as how to implement it https://refactoring.guru/design-patterns/singleton
and here is some info about how it's typically implemented in unity https://unity.huh.how/references/singletons

[spare dome]

sweet, thanks man

[dry jacinth]

Yall know how to fix this???

im following a unclear tutorial

[somber nacelle]

at a guess i'd say you copied the code wrong. make sure your !IDE is configured so you see error underlines in your code and get proper auto complete

[tawny elk]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• :question: Other/None

[dry jacinth]

i need help at the last line

Scenemanager thingy

[spare dome]

read the error completely

[somber nacelle]

get your IDE configured. it is a requirement to receive help here
#archived-code-general message

[dry jacinth]

ok

[somber nacelle]

after you do that, it should be more obvious what you've forgotten

[dry jacinth]

totally didnt just scrap the whole thing 😭

[somber nacelle]

but why . . .? it's an incredibly simple issue that requires literally just paying attention to what you are doing

[dry jacinth]

The tutorial was hard to follow anyway. i rather just work with an actual easy to follow tutorial..

[somber nacelle]

okay, well make sure you get vs code configured if you haven't already. using properly configured tools makes this a lot easier

[dry jacinth]

I have for future scripts, but thank you for recommending it.

[ember iris]

I'm trying to make a method to spawn units in a square/rectangular pattern. Currently it spawns the units in a diagonal pattern. https://pastebin.com/xQMu6j0y

[vestal arch]

a filled or hollow rectangle?

[ember iris]

Filled

[vestal arch]

what's num supposed to be there?

[ember iris]

the number of points that will be in the rectangle

the size parameter is not yet implemented

[vestal arch]

sqrt isn't going to implement that correctly

3 would yield 1 and 2

since there's no clean square for that

[ember iris]

right

[vestal arch]

in fact primes would need to be 1*num

so i don't think num really makes sense as the input there

[vestal arch]

(with nonprimes it wouldn't work either but primes are a clear example)

[ember iris]

I see, so what would you recommend?

[vestal arch]

since it's supposed to be a rectangle, use height and width as the inputs

[vestal arch]

(sqrt(8) is between 2 and 3. you'd get 6 instead.)

[vestal arch]

with that the rest of the logic would be trivial

[ember iris]

Alright.

Thank you for the help.

[ionic grove]

Do you guys know why I'm randomly getting fading for random methods in VS 2022? I've tried flipping the fading settings off and on again, but to no avail

[leaden ice]

What do you mean by fading?

[ionic grove]

Like the letters are faded to a light grey rather than a white

[leaden ice]

What letters

You mean the text in Visual Studio?

[left olive]

it's an issue with VS 17.12. MS have acknowledged the issue.

[ionic grove]

Yeah

[ionic grove]

Ah, ok darn. It's obnoxious.. Thanks!

[upper pilot]

How do I check if my code runs in webgl?
I can't seem to do #if UNITY_WEBGL

I want webgl specific code to run in this case

some examples I Found require some things that I cant figure out, I was able to do it previous with import __Internal or something, but all examples I see seem to require extra code that I never had to write before.
Is webgl special case that only needs to import __Internal?

#if UNITY_WEBGL && !UNITY_EDITOR
#endif

This line doesn't seem to work, maybe I forgot to enable webgl in the project or something 😄

nvm, VS just doesnt auto complete this line hmm

[cosmic rain]

No clue what __Internal you're talking about. The platform defines that you shared should be enough.

[upper pilot]

What do you mean?

I just needed this:

        // Only run this in WebGL mode.
        #if UNITY_WEBGL && !UNITY_EDITOR
        
        PromoImageLinkObjectGlobal.SetActive(true);
        PromoImageLinkObjectMenuOnly.SetActive(true);

        #endif

It wasn't clear in VS since it didn't auto complete UNITY_WEBGL for some reason, but it might work, just need to test.

As for __Internal it is needed for other reasons(not this one probably) but to run some scripts in a browser for example.

It auto completes tons of other UNITY_ lines but not webgl for some reason, so that got me confused 😄

[cosmic rain]

Yes, that should work. If you're uncertain, you should confirm with the docs.

And yes, Internal was probably needed for something else

[upper pilot]

I am surprised but the docs actually have something on it

https://docs.unity3d.com/6000.0/Documentation/Manual/plug-ins-native.html

thats actually good to know, last time I had trouble finding any information on that

[cosmic rain]

This is related to conditional compilation and compiler defines. There are plenty of info in the docs on that:
https://docs.unity3d.com/6000.0/Documentation/Manual/scripting-symbol-reference.html

[upper pilot]

Ah so those werent showing up because my build platform was windows

[upper pilot]

Is there a better way to ignore certain scripts in webgl mode? In my case I need to disable Steamworks scripts, do I just do #if !UNITY_WEBGL around the whole script?

Also its surprisingly quiet here today, what happened? 😮

[rigid island]

pretty much, or assembly definitions is another way but can be potentially be more work

[upper pilot]

So I have to do that for all scripts from steam api? 😐 thats a pain, but I will try, maybe there isnt as much as I think 😄

I guess that I should do that for the content of a class, but not the class itself so it doesnt break when steam engine is attached to a game object?

[rigid island]

only if you have references to that class it would break in webgl

[upper pilot]

so having it on game object is ok even if its disabled with #if?

Because it breaks on compilation, hence why I am not sure, but I will keep trying

I wish there was an easy way to remove whole namespace

[rigid island]

if its on a gamobject thats an instance so yeah its expecting the script

[upper pilot]

alright

[rigid island]

assembly definition is worth a look, you can choose dlls/libraries based only on platform

https://docs.unity3d.com/Manual/assembly-definition-files.html

[upper pilot]

I will check it out, but not sure if I can manage to implement it today.

[rigid island]

more important stuff related https://docs.unity3d.com/Manual/class-AssemblyDefinitionImporter.html#define-constraints

Is this something I should be worried about?
The game has probably quite a bit of assets, but this seems to take too long?
This is not a big 3D game or anything of that sorts + its webGL build.

1gb of files in Assets/Resources

1.14gb Assets folder as a whole

I am expecting issues, so I am asking if I should wait an hour or cancel it 😄

[cosmic rain]

WebGL would take more time than a normal windows build simply because it has to be il2cpp and then compiled to web assembly or whatever it needs to be.

[upper pilot]

I see, in that case I will wait till it reaches 1h or so

[cosmic rain]

That being said, I can't say if it's normal or not as it depends heavily on your project and hardware. See if it's stuck on the same thing for more than several minutes. That might point out that it's actually stuck.

[upper pilot]

No errors in the console, in the past I'd get some errors which were ignored by the compiler until I cancelled it, so this one is promising I think.

[rigid island]

compression also takes longer(smaller filesize but long iirc) it really squeezing all that into a webassembly is pretty impressive

[sinful marsh]

what's the error?

[rigid island]

is telling you. You have 11274 errors

[sinful marsh]

yes, but what are the errors? the cause of it?

[rigid island]

scroll to the top of the errors, start from there

[sinful marsh]

that's it

its 2 error lines

[summer heart]

Does your editor give you more specifics? The language server will usually highlight errors for you

[sinful marsh]

nope is literally just that

[rigid island]

which platform are you building to

[sinful marsh]

plus it very inconsistent, sometimes it builds properly and sometimes it fails

pc, 2022.3.16f1

[leaden ice]

You need to update Unity

[summer heart]

Also idk how big your project is but with 11000 errors I feel like you could open up any file and see a dozen off the bat

[rigid island]

maybe delete the library folder and try again

[leaden ice]

That is a super old version

[sinful marsh]

where is the engine log files located?

[leaden ice]

2022.3.52 is available

[rigid island]

I used that version as my 2022 for a while so idk if the version is broken

Hey, if an object is persistent, (I.e dont detroy on load) when you load into a new scene does the awake function run?

[cosmic rain]

No.

[swift falcon]

Is there difference between general game loop vs iterative game loop. Exm:

While(true) vs for()

[kind willow]

What the difference could be?
Both are loops, but for different purposes

[cosmic rain]

None of these are game loops. They're just loops

[swift falcon]

Yes, what is the difference of purposes. In which situations one is better than other.

[kind willow]

if you need to loop several times with possible jumps I would use for
if you need to do something till something becomes true you need while
that's pretty straightforward tho?

[swift falcon]

For example i have used while loop in my first game to keep game running. And do stuff inside it. Now in unity i used for. minutes ago this question came into my mind.

[kind willow]

well in unity you should just use update or fixedupdate or lateupdate or coroutines ect

[cosmic rain]

You don't need to implement a game loop in unity. It already has one.

Unless you're planning to freeze your game with an infinite loop.

[kind willow]

every frame Update() called, every physic frame FixedUpdate() called, you usually put your code in there

you can make your while(true) loop using a coroutine tho, but that's pretty niche

[swift falcon]

Isnt unity's loop just a main loop which for keep program running? You draw menu, game seperately. I got it like that

[kind willow]

I don't quite get what you mean but look at this
https://docs.unity3d.com/Manual/execution-order.html

there are at least 2 (kidna) independent loops of Update which is every frame and FixedUpdate which is every physics frame

each block on that page is the place of the code your scripts can be executed within

[cosmic rain]

You don't need to "draw" stuff manually. The engine does it for you. That's what it is for.

[soft dome]

Why are the spline animators so damn slow? Theres 20 spline animations running at one point in my scene and they EACH take 1ms+ to complete, resulting in ~30ms cpu frame times... wtf?

[vocal valley]

Hello! I'm **looking for a talk **that I watched some years ago, about doing math in the unit range (0..1), does it rings a bell for anyone?
I know it's a long shot but for the life of me I can't find it again, my google-fu isn't the best. Thanks a lot!

[snow copper]

hello everyone so im wondering i am not new to coding in fact im really good but i do not know how unity works i whatched game makers tool kit and he said to learn the absoulte basics so what are the absoulte basics?

[pastel patio]

Maybe the first basics you can start looking at is how gameobject, transforms and monobehaviours work

Create a gameobject, 3d objects always has a transform component (UI uses rect transform instead)

There you can change it's location, orientation and scale

And add components

Although honestly, you should look at some beginner unity tutotials

That should cover most of what you need to know of 'absolute basics'

[vocal valley]

Thanks, but it's not there. I did ind this one that scartch the subject https://www.youtube.com/watch?v=mr5xkf6zSzk

[soft shard]

If you remember watching it on YouTube specifically, you could try checking your watch history, I believe that is kept for several years back, though I doubt the video may have specifically been titled with "unit range", if it may have been a GDC talk video - the link Simferoce provided is a good way you can use your data with a percentage (between 0 and 1, where 0.5 represents 50%), so if you had a range of numbers between 100 and 1000, and you wanted 750, youd get a lerp(100, 1000, 0.75f) or if you wanted to smoothly transition between 2 points you can lerp with a Vector or Quaternion (for rotations) - you can also mathematically calculate numbers to fit a percentage if you know your range, for example if you wanted 50% of 500, thats 500 * 0.5, or if you wanted to know what percentage 250 is from your max value, thats (250 / 500) * 100 - not 100% sure if that is what you mean with "unit range" or if your referring to a different kind of math, you could try looking up the math terms for that specific kind of math otherwise

[spare dome]

learn some unity and C# #💻┃unity-talk message

[vocal valley]

Sorry, I should have said that I'm not looking for advice on how to do it, but talks about it to share these ideas

[soft shard]

Ah then if its about sharing, going through your YouTube history or looking up the math terms for that specific kind of math might be your best bets, or possibly searching through GDC Vault channels, but that could be a long shot of mostly guessing the title/thumbnail and hoping its there

[prime lintel]

How are C# arrays initialised? If I declare an array of 64 CustomStruct type, will called new() on the declaration assignment initialise empty structs in the array? Or will it be some form of uninitialized garbage value?

[thick terrace]

they're default-initialized (zeroed)

[prime lintel]

Okay thanks

[prime lintel]

Would it be possible to override the default constructor used for default initialization in the version of .NET Unity uses? Since value assignment to members aren't available in this .NET version

[snow copper]

i already know c# pretty well may need a refresher though

[snow copper]

okay thank so much

[thick terrace]

that's just how structs work, even if you use a version of C# that lets you give a struct a default constructor it's not called in all circumstances (like allocating an array) since it's really just a block of memory

[pastel patio]

No problem, good luck Kali

[thick terrace]

if you want a type that can only be constructed by its contructor, you need a class

[prime lintel]

I see, thank you

[spare dome]

in the pinned message I posted there is unity tutorials which will be of use to you, you would also want to learn unity's API if you have not already

[snow copper]

okiedokie thanks

[snow copper]

so you mean c# discord?

[spare dome]

huh? I do not think that is what I posted, this is what I meant #💻┃unity-talk message although you can join it if you have questions for them

Hey guys, anyone got experience with Unity Version Control? Working on a Uni project with my mates, but they can't check in their changes. They keep getting the error "You don't have add, ci permission on [file name]", even though they're all marked as owner in the organization which is inherited on the project.

Nvm, it doesn't automatically assign seats to people joining the project, even if they're an owner from the organisation.

[prime lintel]

How do I assign refs to members of a struct? I wish to pass refs as part of the members of a struct so that a child may store direct refs to data of its 'grandparent'

Or is this not possible

[rain minnow]

do you mean to assign components that belong to a GameObject?

[prime lintel]

No, similar to how you can assign a pointer or reference to another object to allow it access to the data defined by the assignment

std::shared_ptr<CustomStruct> m_attackData = std::make_shared<CustomStruct>();
childObject.m_attackData = m_attackData;

[rain minnow]

that's just assigning the component to the variable . . .

myStruct.refVariable = someComponent;```

[prime lintel]

it seems that my struct is storing a copy tho

[rain minnow]

are you storing the component or a value from the component?

[steady moat]

Yeah, that would be what it does with the solution suggested.

[prime lintel]

I am storing custom struct values

public struct MobAttackData
{
    public bool hasInit;
    public float damage;
    public PropertySet interval;

    public MobAttackData(ref float damage, ref PropertySet interval) : this()
    {
        hasInit = true;
        this.damage = damage;
        this.interval = interval;
    }
}

[steady moat]

That is not really how should do that in C#.

[prime lintel]

Could you suggest how I may do it or point me to some resources regarding this please?

[steady moat]

ref float damage is not something you would expect to work with in a C# environment.

[steady moat]

Use a wrapper.

public MobAttackData(StatisticReference damage, ...)

[steady moat]

If you really insist you could also use System.Func. But manipulating value type data with ref is uncommon.

[rain minnow]

though using ref points to the original value, this would not work since damage is a value type. when the struct is created it becomes a copy. you need to have a reference to the component the value belongs to (that's what i thought you wanted) . . .

[prime lintel]

I'm sorry I don't really understand this, is there a web resource that can elaborate on this particular implementation? So sorry for imposing on you

[prime lintel]

The parent doesnt store everything in a neat way, encapsulation would have me making an ungodly amount of Getters though

[small schooner]

you can do not use Constructor at all and you can just initialize via new var mad = new MobAttackData{hasInit=hi,damage=d,interval =inter}

[rain minnow]

maybe seeing the entire code/hierarchy can give us a better picture. also, what is your intent or the purpose of your structure. there could be a better solution . . .

[steady moat]

public class Statistic
{
    public float Value {get;set;}
}

public class MyClass
{
    private Statistic statistic;

    public void MyFunc()
    {
        new MobAttackData(statistic)
    }
}

[steady moat]

Alternatively

public struct MobAttackData
{
    public MobAttackData(System.Func<float> damage)
}

public class MyClass
{
    private float damage;

    public void MyFunc()
    {
        new MobAttackData(() => damage)
    }
}

[small schooner]

if u use MyClass name -> method with same name is Constructor in your case -> public MobAttackData (ref float damage, ref PropertySet interval) is constructor that have no sense

[steady moat]

Or a more C# object oriented way

public struct MobAttackData
{
    public MobAttackData(IDamageProvider damageProvider)
}

public interface IDamageProvider
{
    public float Get();
}

public class MyClass
{
    public void MyFunc()
    {
        new MobAttackData(new DamageProvider())
    }
}

[prime lintel]

Struct

public struct MobAttackData
{
    public bool hasInit;
    public float damage;
    public PropertySet interval;

    public MobAttackData(ref float damage, ref PropertySet interval) : this()
    {
        hasInit = true;
        this.damage = damage;
        this.interval = interval;
    }
}

LaserDrone : Mob : Monobehaviour

protected override void Start()
{
    base.Start();

    m_health = new(0, m_maxHealth, m_maxHealth);
    m_attack01 = new(0, m_maxAttack01Interval, 0);

    AttachEventHandlers();

    m_weaponSpriteRenderer = transform.Find("Weapon").GetComponent<SpriteRenderer>();
    m_weaponColor = m_weaponSpriteRenderer.color;
    m_bodySpriteRenderer = transform.Find("Body").GetComponent<SpriteRenderer>();
    m_bodyColor = m_bodySpriteRenderer.color;

    m_contextMob.TransitionTo(new LaserDroneType_Mob());
    m_contextMob.RegisterAttackData(new(ref m_maxAttack01Damage, ref m_attack01), 0);
}

MobContext : Monobehaviour - Another component running alongside Mob(Type)

public void RegisterAttackData(MobAttackData attackData, int idx)
{
    m_type.RegisterAttackData(attackData, idx);
}

IType_Mob

public void RegisterAttackData(MobAttackData attackData, int idx)
{
    m_attackData[idx] = attackData;
}

[prime lintel]

I see, this would be something related to what I was envisioning as an alternative solution

Thank you anyways

[rain minnow]

sorry, afk. if i'm correct, it seems like you want to use a struct for tracking changes of your data. a class is preferred. since structs are copies, they're best for immutable data, or data that is changed independently from its copied source . . .

you can create a Stat class if you want to track changes of that value and pass the class instead, or add a method on the struct to update that value for a simple fix, though, you'd have to track when that value changes and update the struct accordingly . . .

[prime lintel]

Nw! It's alright I've refactored my code already, I was under the assumption structs in C# were similar to C/C++

Along with references

[late lion]

The reason you can't do this in C# is because it's a safe language. There are scenarios where you can use ref the same way you'd use pointers in C/C++, but they are very strict to ensure memory safety.

But if you use unsafe, you can do whatever you want.

[rain minnow]

ah, gotcha. yeah, they're value types instead of reference types . . .

[thick terrace]

there are no value/reference types in C++, everything is a "value type" in C# terms

[rain minnow]

also, quick nitpick. if the SpriteRenderer for "Weapon" and "Body" are part of the GameObject hierarchy, it'd be easier to drag and attach those components from the inspector than use Find and GetComponent for each of them . . .

[late lion]

Here's the C# unsafe equivalent of the C/C++ example you gave, but normal pointers because there are no built-in shared_ptr type in C#.

public unsafe struct MobAttackData
{
    public bool hasInit;
    public float* damage;
    public PropertySet* interval;

    public MobAttackData(float* damage, PropertySet* interval) : this()
    {
        hasInit = true;
        this.damage = damage;
        this.interval = interval;
    }
}

[prime lintel]

Gotcha 🫡

[rain minnow]

was just about to ask why not shared_ptr . . .

[thick terrace]

the C# equivalent of a shared_ptr containing a struct is just a C# class, idk why you wouldn't just use that 😅

[late lion]

This looks simple enough, if you can stomach the unsafe, but it's not very useful in C# because you can't easily create a pointer to something that was allocated by the garbage collector, which is everything unless you or Unity allocated it manually.

[prime lintel]

Thanks, didnt know I could actually declare raw pointers.

[rain minnow]

it's just an example of how they can achieve what they were trying to do from the their knowledge of C/C++ . . .

[thick terrace]

i think it's worth pointing out that can and should are very far apart here though lol

[rain minnow]

wait, you're entire game isn't written in unsafe C++? blasphemy!

[thick terrace]

to be honest it's probably better to compare the unsafe features in C# to plain old C than C++ because C# is missing all features like RAII which you can use to make C++ a bit safer

[short quiver]

Hi, I'd like to use a graphical interface to plot a velocity curve and turn it into an array of values. Are there any utilities that exist for this? E.g. in this video, they present visual curves representing the vertical velocity of the character, and these values are hardcoded on a per-frame basis, which is what I want to try in my game
So in the video, for Yoshi, his double-jump velocity is probably something like [-1, -.5, 0, .5, 1, 2, 4, ...], and I want to be able to plot these values and convert them into an array

[crude mortar]

you can use an AnimationCurve

you could either use the intended curve functionality of using a few plotted points (2-4 points) with interpolated handles, or you could technically plot every frame manually by placing points at a certain interval

you could then just use the Evaluate method on the AnimationCurve in a for loop to assign the results to an array

[short quiver]

oh, excellent, thank you, I'll play around with this

[twilit rune]

so i'm trying to create a melee attack hitbox for my player character, but i'm struggling a bit on the enemy detection, should i be turning on an object with a box collider trigger with a script to detect OnCollisionEnter, or create an array with OverlapBox?

i'm trying the former, since its easier to change its position/size, but i want to know if there's a better option

[leaden ice]

Just do a direct physics query

turning on a collider and waiting for a callback has all kinds of weird timing and coordination issues

[patent turtle]

Anyone know why there is no option to merge branches in Unity Version Control?

[leaden ice]

Are you looking at branches? Or the changelist?

[patent turtle]

Branches

I've looked everywhere for an option to merge but it doesn't seem possible

[leaden ice]

Not sure - try updating everything to the latest. If still not working, there are otehr ways to do it, including from the command line, or on the unity cloud dashboard

https://docs.unity.com/ugs/en-us/manual/devops/manual/workflow/merge-branch

I'm not super familiar with UVC, I normally use git.

[patent turtle]

I was told Git use in Unity was a paid feature. Or did they get rid of that?

[leaden ice]

Git is and always has been free and open source software

What you are using (Unity Version Control) is a paid feature (after certain limits)

[patent turtle]

Maybe I've already hit the limit? I am a solo dev so this seems incredibly limited.

[leaden ice]

doubtful

I'm not convinced the plugin in the uNity editor ever had the ability to merge branches

But then again, I haven't used it much

[patent turtle]

https://docs.unity.com/ugs/en-us/manual/devops/manual/workflow/merge-branch

[leaden ice]

Yeah that's what I linked above

but that's talking about the desktop Gui app

[patent turtle]

There is supposed to be an option when I right click so I don't understand.

[leaden ice]

not the Unity Editor plugin

[patent turtle]

It's just a 3rd party plug in? That's seems like a major oversight.

[twilit rune]

so physics.overlap then?

[leaden ice]

Sure

[unique ivy]

Is there a way to tween Transform.LookAt(), or achieve a similar result through other means? (Slerp probably) LeanTween makes me feed in the necessary rotation, which I don't know how to calculate

[leaden ice]

Sure of course. LookAt merely modifies the object's rotation

To calculate the LookAt rotation you'd do this:

Vector3 direction = targetPos - myPos;
Quaternion targetRotation = Quaternion.LookRotation(direction);```

You could also tween an object between where you're currently looking and where you want to look and LookAt that object.

Same effect.

[soft shard]

Git is not a paid feature, though there are a few steps involved to get it setup with a proper .gitignore file for Unity, and there can be limitations with pushing large asset files, using git LFS becomes paid for increased storage, but aside from that, its essentially free and you either access it through a website, console/terminal or with a gui program like "github for desktop" or "source tree", etc

[leaden ice]

using git LFS becomes paid for increased storage
For the record git LFS and Git itself are completely free and open source software.

If you choose to use a cloud hosting Git Repository provider such as GitHub, you will need to pay for certain things.

But if you want to self-host a git repository you can do so without any limits

[patent turtle]

I'd really prefer to just use Unity built in mechanics but it seems they don't work at all.

I just used Unity Dev Ops Version control and I nearly lost everything.

[soft shard]

Ah good point you bring up, I was referring to github specifically as thats whats often used, where limitations exist, but you are right that if your self hosting your limitations is on your own hardware then (though I personally havnt tried that myself)

[patent turtle]

Like it said it merged branches but I didn't see any of my changes once I switched back to my main branch.

[leaden ice]

Yeah I'd really recommend using real battle-tested version control aka Git

There's way more support and knowledge for it in the world

[patent turtle]

It just seems weird that it doesn't work. Don't pro studios use this?

[leaden ice]

I'm sure a few do

I would wager most use Git

[patent turtle]

I'm just weary of using anything that isn't meant to work with Unity

[leaden ice]

Although some may be swithcing to it to fulfill certain contractual obligations for enterprise customers these days

[leaden ice]

Git is meant to work with everything

There's nothing special about a Unity project in terms of version control

[lean sail]

Git is the standard in quite literally every other field of CS. You dont need integrated version control, especially since these arent as good

At least when I looked into it a year ago, some other version controls didnt even have the same basic features as git.

[patent turtle]

Like merging branches?

[lean sail]

I dont remember exactly what it was, but some dont even let you edit a file the same time as someone else.

[soft shard]

Unity has also rebranded their version control I think 3 times now (used to be "Collab" then Plastic, then UVC), as there seemed to always been a feature youd find in a regular git missing or not functioning as expected, im sure its a great tool because its integrated with managing asset files like scenes and prefabs well, but you can also do that with a few more clicks outside of Unity (though I havnt used UVC in a while)

[patent turtle]

So yeah this is the very reason I am afraid of using any other source control

I don't want my prefabs and assets getting messed up.

[vestal arch]

they won't most likely

use the premade unity .gitignore and you'll be set

[leaden ice]

why would they get messed up?

they're just files

[lean sail]

Youd have to mess up pretty badly to do this. Which doesnt matter anyways because you'd be using version control and can revert

[vestal arch]

slap a .gitattributes with * text=auto eol=lf if you feel like it

[soft shard]

From my experience, using github externally, I never really had issues with files getting messed up, but like any tool, it does take time to learn, however, it is advised not to work on the same scene as someone else, files wont get messed up, but you may have to "diff" those files

[vestal arch]

git is meant to work with everything else, it's a much more general tool; ides have git integration, and if you learn git you'll be able to use that for any other project since it's nonspecific

[patent turtle]

Github is a paid service unless I want to expose all of my work to the rest of the world right?

[vestal arch]

no

[leaden ice]

no

[soft shard]

Thats actually handy, I didnt know about thee eol attribute could be done with git

[vestal arch]

you can make private repos for free on github

[leaden ice]

it's free to have private repos

[vestal arch]

(has anyone mentioned the *hub comparison to explain git vs github yet)

[patent turtle]

Yeah I get the difference. I've used github for a few mobile projects. I was under the assumtion that you couln't have private repos without paying monthly for them.

[lean sail]

How long has that been a thing.. I've been paying lately since my free student deal ran out

[leaden ice]

several years now

[spare dome]

you've been paying for the private repos on github?

[leaden ice]

I think because GitLab or BitBucket started offering free private repos GH had to start doing it

[somber nacelle]

the change was in like 2019

[lean sail]

When I started, private repos weren't free

Oh wow, til

[patent turtle]

Same

[spare dome]

correct they were not

they updated it now, which is nice

[soft shard]

If it helps: https://github.com/pricing - first column "free, 0 USD/month", explains public/private repos (and other limitations)

[lean sail]

I havent looked at the actual pricing/plans ever since I got my student deal 😂

[spare dome]

I just use github for free and it has been working for me ever since

[soft shard]

Tbh, neither did I until I compared github to gitlab a while back lol

[spare dome]

I would like to look at more git based Version control but I don't know of many other than github

[soft shard]

Ive only ever used github, gitlab, bitbucket and " TortoiseSVN", the latter was my least favorite

[spare dome]

TortoiseSVN is a version control software? I did not know that or I'm confusing it with something else

[thick terrace]

kind of, SVN is the version control bit, tortoise is a gui for it

[rain minnow]

oh wow, i never knew you had to pay for that. luckily, it was free when i started using it . . .

[spare dome]

interesting, never used an SVN based version control system before, I always used git based products as it usually works well

[soft shard]

Yeah, ive only used TortoiseSVN on one project and it was... Much more awkward than using github/lab for sure, but im sure it came down to unfamiliarity... At least thats what the boss on that project said

[leaden ice]

I used SVN/Tortoise in my first job out of college, it was alright.

Git is better 🙂

[spare dome]

yes git is 110% better, its very easy to use as well and the GUI's (most of the time) are great, I have not used git's SLI either at all or not to much, I do not remember

[limpid ibex]

Hello, what is the most optimized method for placing an object picked up in the hand?
Simply have all the 3d items placed in advance and activate the one you've picked up and deactivate the others?

[latent latch]

"Simply have all the 3d items placed in advance and activate the one you've picked up and deactivate the others?"
It's a fine idea assuming you've a limited amount of weapons a character can have.

[limpid ibex]

yeah. Otherwise I guess you'd have to store the mesh item on the object and retrieve it dynamically?

I'm working on a multiplayer project, and I want to avoid sending too much data to the server.

[latent latch]

If we're talking about Doom, and similar type of games where you've got like 10 weapons max then I'd go with the activate/deactive route. If it's Borderlands where there's hundreds of different weapons that can be generated, then you're looking into new()ing/Instantiating the weapon onto the player when they retrieve it most likely

Rather, if you're doing some drop system that has weapon variance then you'd instantiating on the drop, then read in its configuration and childing it to the player on pickup*

[limpid ibex]

so read the object's data and update the player's hand with the data.

I don't know how many items I'll have in play.

[latent latch]

If you've no variance on your weapons, such that a broadsword does 7 damage like any other broadsword, then you simply need to serialize the IDs of that item. If the weapon can randomize range of damage from 5-7, then you're usually passing in a struct of data instead of just an ID.

Least of your problems though relating to networking serialization

[glad idol]

Hey, i would i appreciate if I got some insight on this problem

Quaternion rotationY = Quaternion.AngleAxis(currentRotation.y * parallaxRotationScale.y, Vector3.up);
Quaternion combinedRotation = rotationX * rotationY;

Quaternion finalRotation = Quaternion.Slerp(
    combinedRotation * Quaternion.Euler(rotationOffset),
    rotObj.transform.localRotation,
    slerpScale
);
rotObj.transform.localRotation = finalRotation;```

i've been struggling with this for a couple of days; im trying to have an omni-directional rotate for the obj rotObj based on player perspective, aka the Camera

the rotationX works just fine, leaning up or down no matter what orientation, due to it being based off the camera POV,
but rotationY is being stubborn, and refuses to pivot on the Y axis

[latent latch]

What's the idea around doing all that work with quaternions only to tack on some offset in eulers near the end

also when you're combining rotations in xyz fashion usually it's ~~z -> y -> x ~~ z -> x -> y like Andy mentioned below (but assuming you don't use unity's eulers methods you can order however you want as long as you stay consistent)

[glad idol]

Might be the issue, I think that was left behind from old solutions

[glad idol]

For Quaternions?

[latent latch]

yeah, they aren't communitive

or is it associative. I forget which is which

[glad idol]

Interesting, I’d have to research more on Quaternions and Eulers

[latent latch]

eulers , as far as unity methods go I think default by multiplying ~~z -> y -> x ~~ z -> x -> y

[placid summit]

it is z,x and y as per docs

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

[vocal drift]

hello, so i have weird problem, and thank you if anyone helped,

i don't know why, but my private variable suddenly changed on runtime, even nothing change it both in the inspector or in its own script,
the weird private variable is inside ScriptableObject, and the ScriptableObject is inside an enemy
name of the variable is enemyGroup with type List<Character>,
i thought something wrong with my unity, so i tried to restart my laptop
here's the full script of it : https://paste.ofcode.org/ND377n7fS3HGXcMurcVyRJ
and i also provide a video

[thick terrace]

maybe this? you're assigning the same list to both enemySpawn and enemyGroup then clearing it

well, clearing it next time that method gets called i guess

you also have methods returning enemyGroup by reference so it could be cleared from elsewhere in the code

[dusk apex]

Can you show an image of the full error/stacktrace in the console window?

[vocal drift]

The error doesn't have any relation with this script, its another error

Wait let me turn my laptop on

[vocal drift]

I only change the enemySpawn List, never change enemyGroup List

[knotty sun]

do you not understand that when you do list = list they become the same list

[vocal drift]

yeah i know,
if ListA have a,b,c
and ListB have nothing

if ListB = ListA

then ListB wil have a,b,c

is that what you mean?

[knotty sun]

no not at all
ListB is just an alias of ListA, it is not a List in it's own right

[vocal drift]

ListB is independent, so if i change anything in ListA, ListB will still the same unless i change ListB

[knotty sun]

no

[crude mortar]

not in this example

I think what you want to do is ListB.AddRange(ListA)

otherwise ListB ceases to exist. You would be left with just ListA in memory (ListB variable would just point to ListA internally)

[vocal drift]

wait, let me think

[vocal drift]

what's this code does?

[crude mortar]

adds all the elements in ListA to ListB

[vocal drift]

so basically, what happend in my code is ListA value is connected to ListB, so if i change one of them, others will also changed?

[crude mortar]

yes

[vocal drift]

ahh ok, i just realize that, thank you btw

[knotty sun]

be careful though. AddRange is a shallow copy.
in your case the Character references pointed at by the Lists will still be the same ones, not copies

[vocal drift]

okay

[thin aurora]

If variable a is a reference type and you assign b to a, you assign the same thing

I suggest you learn the difference between reference types and value types because it's actually really useful to understand what these are

If you want to create an independent list, create a new list and use the constructor that accepts an existing list. This effectively clones the list

Note that if the list holds reference types by itself, these will also be the same as the entries in the other list

I see SteveSmith also pointed this out already

[vocal drift]

i have to translate all of that then read it carefully phrase by phrase, but thank you

[thin aurora]

Just look up reference types and value types in C# and also the difference

That's the important part

[wispy raptor]

i wanna do a function to restart a video player and when it is called:
1- Video stops
2- Video is reseted to the first frame
3- texture showed is the first frame of the video.

Hey guys, don't know where's a good place to ask this so I'll ask here. Does anyone know of an Ad SDK that permits you to reward rewarded ads with crypto? AFAIK Google's policy disallows this, specifically any reward with financial value.

[jagged plume]

how would you guys call the button in the credits to go back to the main menu ? Like "Back" ? "Menu" (like here) ? "Title" ?

Call it whatever you want, or use a an icon, this isn't a coding question.

usually Awake.
Start when you want something to happen after other initialization is done (including initialization that other scripts do, like when instantiating this object as a prefab and setting up some values first)

[gaunt raven]

I have a problem with my 3D player character that can slide and crouch. For some reason, if the player slides into a wall and then jumps, the jump detection system stops working. Specifically, this part of the code stops functioning:
Physics.Raycast(origin, direction, out hit, ray_Distance);
I have no idea how to fix this.

[leaden ice]

what does "stops funcitoning" mean exactly?

What debugging steps have you taken?

Is the code still running?

        Physics.Raycast(origin, direction, out hit, ray_Distens);

        if (hit.collider.CompareTag("Ground"))
            can_Jump = true; // if it found ground                                                       
        else
            can_Jump = false; // if there is no ground```
I will say onet hing - that this code isn't even making sure there was actually a raycast hit

You are ignoring the return value on Raycast

[gaunt raven]

Yes, everything else works. Debugging involved slowly and painstakingly figuring out whether the issue was with the Raycast or something else. It turned out to be related to this part: Physics.Raycast(origin, direction, out hit, ray_Distance);. After the event, it doesn’t update.

When I say it "stops functioning," I mean it stops updating the can_Jump variable.

[leaden ice]

if the raycast doesn't hit anyhting, this code is going to cause an error

[leaden ice]

It's definitely updating the variable

assuming it's still runing, and there is no exception

are you looking at the console window?

This is why i asked what debugging steps you've taken

you need to check

• If any exceptions are being thrown
• If this code is actually running
• What the result of the raycast is if it is running

[gaunt raven]

aaa

[leaden ice]

Debugging involved slowly and painstakingly figuring out whether the issue was with the Raycast or something else
But what debugging steps did you take?

With Debug.Log figuring this out would take about 2 minutes, it would not be painstaking

[gaunt raven]

ill come back with debug lists and come back

[gaunt raven]

kinda did but also removed becues "i felt like a smart fellow" XD

private void JumpingPlayer()

    Vector3 origin = transform.position + ray_Offset_Down;                                               
    Vector3 direction = Vector3.down;

    Debug.DrawRay(origin, direction * ray_Distens, Color.red);
    //hit = Physics.Raycast(origin, direction, ray_Distens);

    Debug.Log($"DEBUG JUMPING : hit colider object = {hit.collider}");

    Physics.Raycast(origin, direction, out hit, ray_Distens);

    Debug.Log($"DEBUG JUMPING : Physics.Raycast reslut = {Physics.Raycast(origin, direction, out hit, ray_Distens)}");

    if (hit.collider.CompareTag("Ground"))
        can_Jump = true; // if it found ground                                                       
    else
        can_Jump = false; // if there is no ground

    Debug.Log($"DEBUG JUMPING : can jump is = {can_Jump}");
}

[leaden ice]

Ok so... why are you just ignoring that exception?

Like I said you need to actually check if the raycast hits something

[gaunt raven]

how do i do that

[leaden ice]

if (Physics.Raycast(origin, direction, out hit, ray_Distens)) {
  // we hit something
}
else {
  // we didn't hit anything
}```

sorry i am so lost

[somber nacelle]

notice how you've just put that if statement after your actual raycast and the code that is throwing the exception when the raycast hits nothing

[gaunt raven]

aaaaa

fuge

[rigid island]

hit.collider is outside raycast if statement that defeats the point of having that if statement, you can only log hit.collider.name, if the hit actually happened

[lyric belfry]

Don't be afraid to snag the code line numbers in screenshots lol

[rigid island]

or just share the code properly and not screenshots

[somber nacelle]

do you understand what the actual purpose of the if statement is?

[gaunt raven]

in what part

[somber nacelle]

wdym "in what part"?

[rigid island]

the raycast

returns a bool.

[gaunt raven]

aaaaaaaa

this hurts

[rigid island]

why do you think Raycast returns a bool

[leaden ice]

Do you understand the meaning of any of the code?

[gaunt raven]

so then one can get the result of it hitting an object form there it saves values (or well i thing )

[gaunt raven]

yes

[rigid island]

so if it tells you if it hit something. using the result, why are you using the result outside that statement

[leaden ice]

Then it should be pretty straightforward and you would realize it doesn't make sense to have multiple Raycasts here

[gaunt raven]

you mean this part

[rigid island]

yes, how could you log the name of a collider that might be null? hence your error

[gaunt raven]

i ripped the raycast form a nother thing i was working on in the pas with 2d

[gaunt raven]

if it is empty then there is no hit

[rigid island]

you cannot access the propery of a null object, name is a property of collider
if your raycast hits nothing, that line returns error

[gaunt raven]

man i must look like a bit as troglodyte rn

XD

[lyric belfry]

Not really. You are learning.

[rigid island]

yes this belongs in #💻┃code-beginner though

[gaunt raven]

well i know enuff i just thot of somthing else and my mide was not set that i had fliped up the raycast system (meaning the understandment)

becues i got a hang of it in the 2D verson and now realising 3D in a bit more compleax

[rigid island]

in this channel you should be expected to know the purpose of the code you post or how nullref works

anyway, the fix is simple and you should remove the raycast without if check

[gaunt raven]

ye like this

[rigid island]

the compare tag can still throw null, do you not see why

read the logs again carefully, you wrote them lol

[gaunt raven]

aaa

if it isint null and that hit has tag

like this

[rigid island]

I mean.. you could've just put it in the if statement of raycast

that works too

[gaunt raven]

XD

[jagged plume]

is there a way to prevent "assuming" the case for the asyncLoad variable initialization?

e.g. I'd rather have this format

[somber nacelle]

just pass in the actual name of the scene you want to load as nextSceneName and pass that to LoadSceneAsync

[gaunt raven]

ye now i am seeing more of the problem

[jagged plume]

oh

holy fuck man

i'm tired

thanks lol

[rigid island]

btw the can_jump = false should probably be in the else of raycast also

if else is redudant though you can just make a variable for the raycast

[gaunt raven]

ye like this

[rigid island]

bool hitSomething = Physics.Raycast(etc..
isGrounded = hitSomething && hit.collider.CompareTag(etc.))

[gaunt raven]

aaaaa

meaning is just a bit eayser to rework it a bit more. thanks guys for all the help. and next time ill be in the beginner XD

[jagged plume]

Do you guys know how to prevent the preselection of the first button ? (canvas)
Setting Navigation to None does not seem to change anything

[hidden compass]

what about eventSystem.SetSelectedGameObject(null); ?

    public void ClickReset()
    {
        menuEventSystem.SetSelectedGameObject(null);
    }``` my menu script calls this function everytime I click a button or slider so it doesn't remain selected afterwards..
probably could call it in Awake() or Start() for ur usecase

Hello fellas, can somebody help me with Unity's Behavior Graph? Just tried to test it, but seems like serialization of private non-BlackboardVariable doesn't work or maybe I just do it wrong somehow?
Following docs: https://docs.unity3d.com/Packages/com.unity.behavior@1.0/manual/serialization.html
Right now I use 1.0.5 version and this is content of custom action node:

[Serializable, GeneratePropertyBag]
[NodeDescription(
    story: "Search <b>Ability</b> in [unit] and saves to [saveTo]",
    category: "VOIDRPG/Blackboard",

[storm lagoon]

ok so uhh idk if this is good for this channel but

uh how do i fix the package named "com.unity.settings-manager" failing

Library\PackageCache\com.unity.learn.iet-framework\Editor\Core\FrameworkSettings.cs(3,19): error CS0234: The type or namespace name 'SettingsManagement' does not exist in the namespace 'UnityEditor' (are you missing an assembly reference?)

i cant find ANY solution

i just wanna do some MR things :(

[cosmic rain]

Version compatibility issue probably

[storm lagoon]

wha-

these are the packages that come when u make a project

trying to use

the MR package

[cosmic rain]

Is that a project from unity learn?

[storm lagoon]

yes

the MR one

also

[cosmic rain]

No clue what MR is

[storm lagoon]

it didnt install becuase unknown command futime

and it stands for

Mixed Reality

[cosmic rain]

But make sure that you're using the same editor version

[storm lagoon]

its for VR headsets

im using the latest

[cosmic rain]

Do they?

[storm lagoon]

well the editor version is the latest

on the unity project

[cosmic rain]

Do they use the latest editor version?

[storm lagoon]

WDYM

[cosmic rain]

Share the page where you got this project from

You said it's a unity learn project, so it must be from a tutorial?

[storm lagoon]

this is what i mean

i think this is unity learn

idk

[cosmic rain]

It's the hub. Has nothing to do with unity learn.

Try deleting the library folder

[spare dome]

do you have the settings manager package?

[storm lagoon]

what is that

i havent used unity in SOOOO long tbh

[spare dome]

it's a package it looks like you need in the package manager as it is missing a reference to it

I have never used it though

[storm lagoon]

yea uh

its com.unity.settings-manager

[spare dome]

so you do have it? That is the package name yes

[storm lagoon]

no

[spare dome]

if you do have it you can try what dlich said

[storm lagoon]

it says

invalid command: futime

or something like that

[cosmic rain]

Sounds like that's the underlying cause of the issue. Either a connection problem or access rights

[storm lagoon]

i srs do not know

im using a usb

i have 19 gb free

fat32

[spare dome]

usb?

[cosmic rain]

USB?🤨

[spare dome]

you have unity installed to a USB??

[storm lagoon]

...yea why

i dont have 12 gb on my computer

and i dont wanna delete steamapps/common (90gb :D)

[cosmic rain]

Well, it's probably not gonna work correctly with an external storage.

[spare dome]

No wonder it cannot access anything, you are not supposed to have it on an USB

[storm lagoon]

but it let me

i used the actual EXE

[spare dome]

what .EXE?

[storm lagoon]

the unity 6 installer

[cosmic rain]

"not work correctly" doesn't mean you wouldn't be able to launch it at all. It means that there would possibly be problems, like the one you're facing.

[storm lagoon]

well it could load into the editor but with that error

[cosmic rain]

Well, try to install it on an actual internal storage.

[storm lagoon]

i cant

[spare dome]

so you offline installed it onto a USB, which you are not supposed to do. You should instead install it via unity hub online and on the actual C: drive

[cosmic rain]

Then there's not much we can help you with.

[storm lagoon]

i cant load it in like 4gb

how am i meant to fit 12 gb in 4

wait no

6.91

[cosmic rain]

Do you only have 4GB on your PC? Is it 20 years old or something?

[spare dome]

you cannot, also you shouldn't push your hard drive to the limit like that as it could cause damage over time

[storm lagoon]

actually

6.91 gb FREE

outta 471 gb

[cosmic rain]

Well, delete something

[spare dome]

how did you fill up 512 gb hard drive that much 👀

[storm lagoon]

one video game series + mods

its like 90

and the rest is idk

90 GB*

man even with deleting downloads TWICE i still had like 400gb left after a while on my old 2tb pc lol

and i had like a bajillion UNITY versions on that

but this is off topic

[sleek bough]

@storm lagoon This is not tech support channel. Install Unity properly to any location through the Hub.

[storm lagoon]

ok ill stop

and go be sad because i cant even try doing something fun

[cosmic rain]

You have something taking up 300GB+ and you don't know what it is?😅

[storm lagoon]

its just alotta >1gb files lol

[spare dome]

better purge some of those files

[storm lagoon]

bro id rather not delete shit

i alr have like ten filled drives

(usb's)

[sleek bough]

@storm lagoon I'd rather you stop posting off-topic.

[storm lagoon]

ok

ill stop talking

[worn flare]

does anyome know how to allow the player to drop an audio file into the game

[fleet gorge]

Like drag and drop?

[worn flare]

yes

[fleet gorge]

https://github.com/Bunny83/UnityWindowsFileDrag-Drop

Quick search led me to this

[worn flare]

very epic thank you

[fleet gorge]

Only on windows and must be built

[worn flare]

i think the thing im using to convert audio files is windows only too so its okay

[scenic birch]

GRAAAAAAAAAAA

this might not be the place to ask but does anyone know what might be causing my monobehaviour functions to be showing up as unused in VS

i have the visual studio extension installed

this only started happening a few days ago

this class inherits from monobehaviour

FOR ANYONE LOOKING AT THIS LATER SOLUTION IS HERE:
https://developercommunity.visualstudio.com/t/Private-Unity-messages-incorrectly-marke/10779025

[rain minnow]

it shows as unused because you don't manually call it. Unity invokes the event function through reflection . . .

[spark stirrup]

Does anyone know why my player slides across the ground when I stop moving?

https://pastebin.com/SEPZEg4e

[scenic birch]

VS has never showed me this before now

i know it's not literally manually called but is there a way to get rid of this?

just for the monobehavior functions

[rain minnow]

it's probably from an update. maybe you can remove the suggestion from your IDE settings . . .

[scenic birch]

you probably have this set to 0

[rain minnow]

they already have a FixedUpdate method and they do handle movement in FixedUpdate . . .

[scenic birch]

i am stupid.

[rain minnow]

also, using deltaTime in FixedUpdate automatically changes it to fixedDeltaTime . . .

[spark stirrup]

it is set to the default 0.05

[scenic birch]

i shouldnt have tried to help 😭

i honestly didnt know that

[spark stirrup]

But I don't want to increase drag because it doesn't get rid of the problem, it just makes me have to increase my player speed, which also increases the amount of slippage so it's basically useless to increase it

[scenic birch]

https://docs.unity3d.com/2021.2/Documentation/Manual/class-PhysicMaterial.html

[leaden ice]

Because objects have inertia

[scenic birch]

this might be helpful, hopefully i'm right this time xd

set your ground/player to a physics material with higher friction

[spark stirrup]

is there a good way to remove it?

[leaden ice]

If you want to immediately set the velocity to zero, there's nothing stopping you from doing that in your code

[spark stirrup]

I've tried and for some reason that doesn't work

[leaden ice]

But physical objects don't act that way naturally

[scenic birch]

@leaden ice thank you for helping me with my many mirror questions a few years ago :)

[leaden ice]

What did you try exactly?

[spark stirrup]

rb.velocity.Set(0, rb.velocity.y, 0);

[leaden ice]

Yeah that's not right

rb.velocity =

[spark stirrup]

that throws an error

it told me to use Set()

[leaden ice]

Not generally no

You did something wrong

What did you write and what error did you get

rb.velocity = new(0, rb.velocity.y, 0);```

E..g

[rain minnow]

i'd remove multiplying by deltaTime when using force. basically, by doing so, you've manually changed the ForceMode to Acceleration . . .

[spark stirrup]

i tried it again and didn't get the error so I have no clue what I did wrong earlier

So now the player doesn't slide, but for some reason the camera like bounces let me take a video rq

[leaden ice]

If you mean it's jittery that's generally due to a lack of functioning interpolation on your Rigidbody

That can happen if you didn't enable interpolation or if you do something to break the interpolation, such as directly modifying the object's Transform

[upper pilot]

How do I prevent "selecting" buttons?
In my project I use space for certain things, but when clicking a button space would activate that button until I click outside to "deselect" it.
I never experienced it before, but it seems like a big issue to me.

[thin aurora]

Newest VS is bugged, that's why it does this

Before it would correctly show it as methods called itnernally and not unused

[vocal drift]

hello, so i want to use event with parameter, but functions that subscribe the event don't have to use the parameter

i know i can do this, but i don't want to

void Start()
{
  eventProvider.OnSomethingHappend += Subscriber;
}

void Subscriber(string blank)
{
  // blank is never used
}

instead, i want something like this

void Start()
{
  eventProvider.OnSomethingHappend += Subscriber; // no error in this line
}

void Subscriber()
{
  
}

[thin aurora]

Pass the parameters and don't use them?

Alternatively, pass the parameters and have the event handler method call another method that doesn't use the parameters

These things are basically required so you can't work around them

You can also place a delegate on the event directly but I suggest you don't do that since you can't unsubscribe from these since they're not tied to an actual method. Even then, the delegate must reference the parameters regardless

[vocal drift]

what's actually happend in my case is, i have one event with parameter, and there's two function that subscribe it, one that require parameter, and other one that don't require parameter, i don't really want to make a mess so i don't use code example above

or maybe i should use two different event

[thin aurora]

There's no "mess" when you have unused parameters

This is very common with events

Also, event handler methods should purely exist to handle the method, so it would be clear why a parameter is unused

But, if you want it to be even more clear, you can make your parameters _, __, ___ and so on to indicate they are discarded

This is an actual .NET feature, albeit usually for method variables and not parameters so they are not actually supported in this case

It indicates you are aware there is a variable, but you don't use it

[vocal drift]

Okay then, maybe i should ask my senior first

[thin aurora]

My experience with senior is that they tend to give some old and horrible C++ solution so I'm not sure if this is the best idea

[ornate swallow]

Anyone know how to make unity games require double swiping when using gesture navigation in android? and how to make it recognize as a game?

I already tried using a custom manifest and adding android:isGame=true and android:appCategory=game

[cosmic rain]

any "unity games"? Or specifically the one you're working on?

[ornate swallow]

the one I'm working on, sorry!

should've clarified

[cosmic rain]

Well, you'll need to implement it. There's no built-in double swipe feature.

[ornate swallow]

I'm pretty sure it's part of android gesture navigation tho

fullscreen apps typically require double swiping from the bottom to go to the home

altho google hasn't been very helpful with figuring this out, so I could be wrong

[cosmic rain]

I don't seem to have such a feature on my phone. If it is an os feature, it should work with any app, including unity games.

[ornate swallow]

do you have the 3 buttons on the bottom of your screen when you use your phone?

back, home, task view?

(also, about to go in a meeting, will return ASAP)

[cosmic rain]

Yes

[trim schooner]

I believe for iOS it's a tick box in the player settings. I haven't thought about looking for it for Android

[trim schooner]

Android has an option to change to gesture controls, making it the "same" as iOS - no idea when this got added

(in case you weren't aware)

this is a code channel, and your question isn't code related. Delete and move to #📱┃mobile

[fluid siren]

np. thanks for letting me know 👍

[trim schooner]

this isn't a code question either, delete and ask in #📱┃mobile as well

[shy oyster]

I have a quaternion, how do i get the angle for a specific axis from it? like the rotation on the Y axis

[cosmic rain]

You can convert it to Euler angles and use the value of the desired axis.

Would love to hear what your senior said

[tawdry kite]

Hı, i followed a car movement tutorial with wheel colliders and rigidbody but my car is so slow. Do anyone know how to make it faster

Ive tried to fix it with chatgpt but none of his ideas fixed

Nobody knows how to make it faster until your share your !code and define what "slow" is in this case. I'd assume in terms of speed, not code?

[rustic ember]

Hi! When loading a scene asynchronously, does it also run the Awake() and Start() functions of enabled objects asynchronously? Or will the game crash/freeze if there are too many operations?

[thin aurora]

It runs synchronously or asynchronously based on the method signature

I.e. if the method returns Awaitable, it will be asynchronous just like anything else

There's not really an async in Unity I believe. It's all synchronous with some tricks

I'm still not fully sure what it does

[leaden ice]

Unity is single threaded except for very special circumstances

[rustic ember]

Thank you both. Can I make the LoadSceneAsync wait for an IEnumerator to run?

[rain minnow]

Hah, I figured as much. That's usually the case . . .

[rustic ember]

So I can force it to wait for an IEnumerator this way?

[thin aurora]

If you mean it will wait for Start to finish then no

I believe Start works independetly and your scene loading has nothing to do with it or the order of execution

I believe Unity only ensures Awake runs first, then Start

[rustic ember]

Ah, okay. What if I put it in Awake()?

[thin aurora]

Well same thing

Is your issue that you must wait for something to initialize in another scene?

[rustic ember]

The thing is, I have a world generator that is an IEnumerator, and I want it to finish before switching scenes

[rustic ember]

Yeah

[dusky lake]

https://docs.unity3d.com/ScriptReference/AsyncOperation-allowSceneActivation.html

let the generator finish, then manually activate the new scene

[maiden heath]

https://pastebin.com/74eZXpGf

I want to make a system where:

• if there's a yield return, then it will wait for the animation to finish before executing the next animation
• if there's a StartCoroutine(), then it will execute the next animation without waiting

But for some reason, when I run the game, the longer animation (which is _drumsInstrument) wont wait for the shorter animation (which is _fluteInstrument) to finish.

This is what shows for me

Nevermind; fixed the issue.
It was the Has Exit Time property 🙃

[ornate swallow]

from what I understand I have to use setSystemGestureExclusionRects in android to make it defer the home gesture in gesture navigation mode, but it's not clear where I should do that. does anyone have any tips?

[sonic venture]

How do I load an animationclip into a Unity project from files?
I have an .anim called Idle and I want to modify a game's idleAnim. How do I do it? I'm talking about modding here, but I'm curious about the Unity specific 'loading'. Do I use assetbundles, or resources.load?

[unborn elm]

Hi,
I have a base dictionary with a generic object and an enum for my stats that all scene objects use and its working well.

public class StatsInfoDic : IEnumerable<KeyValuePair<StatsInfoTypeEnum, object>>
{
    private Dictionary<StatsInfoTypeEnum, object> _dict = new Dictionary<StatsInfoTypeEnum, object>();

    public void Add<T>(StatsInfoTypeEnum key, T value)
    {
        _dict.Add(key, value);
    }

    public T GetValue<T>(StatsInfoTypeEnum key)
    {
        if (_dict.TryGetValue(key, out var value) && value is T)
        {
            return (T)value;
        }
        Debug.LogWarning("key value does not exist of " + key.ToString() );
        return default;
    }
    public IEnumerator<KeyValuePair<StatsInfoTypeEnum, object>> GetEnumerator()
    {
        return _dict.GetEnumerator();
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        return _dict.GetEnumerator();
    }
}

The problem is that is quite a lot of work to get values (statsInfoDic.GetValue<type>(StatsInfoTypeEnum)) so right now I have started to build a wrapper class that basicly does things like this:

public class Stats
{
  public StatsInfoDic statsInfoDic;
    public void Add<T>(StatsInfoTypeEnum key, T value)
    {
        statsInfoDic.Add(key, value);
    }
    public T GetValue<T>(StatsInfoTypeEnum key)
    {
        return statsInfoDic.GetValue<T>(key);
    }
    public Stats()
    {
        statsInfoDic = new StatsInfoDic();
    }
    
}

And I started adding functions like this:

    public Faction GetFaction()
    {
        return statsInfoDic.GetValue<Faction>(StatsInfoTypeEnum.faction);
    }

The question is if there are any better ways around this or do I need to add this for all my enums? I could of course do something like GetString, GetFloat etc but wondering if anyone has done anything similar and come up with anything smarter

[steady moat]

Would statsInfoDic[StatsInfoTypeEnum] works for you ?

[unborn elm]

Yeah that would work really well I think

[steady moat]

Then you can use indexer. https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/indexers/

However, you will not be able to return generic type like you are doing, instead I suggest that you return an object such as Statistic that will be implicitly cast to the type you want

In other words, something like.

Dictionary<StatsInfoTypeEnum , Statistic> dict
this[StatsInfoTypeEnum type] => dict[type];

public class Statistic
{
    public static implicit operator float(Statistic s) => s.GetValue<float>();
}

It really is just something I would try.

I did once something similar but it did not fit my needs.

[unborn elm]

Great, reading up on it now, havent used it before

[steady moat]

Also, the reason why it did not work for me is because I had to feed parameters (Context, because of my statistic are context aware) to my GetValue which is not possible with implicit conversion.

However, down the line, I feel it was a mistake to make them context aware so I would suggest to not do that (-do not make them context aware-).

[unborn elm]

Thanks so much, great to get some feedback. Im not that experianced and havent really built that much around generics before so really valueble with input

[dense edge]

hello, im having trouble in my game using navmesh. im making a city builder that uses navmesh, but the map is quite big, there is also verticality with bridges and otehr things of the type. i cant find a decent way to add walkable navemesh areas after i create a bridge. is its possible to make update the navmesh winthout rebaking everything?

[rigid island]

navmesh surface you can bake them individually

[dense edge]

? i dont undertand its possible to break the navmesh in to smaller ones and bake them individually?

[rigid island]

yes of course, they also can be sectioned off into specific areas / volume

[dense edge]

can you give the component name or functions that can do that?

[rigid island]

I just told you lol Navmesh Surface component, then look at the different modes of baking / collecting objects to bake

[dense edge]

oooh ok

[rigid island]

api is here

Source generator dll's stored in the Assets folder are not supposed to apply to to assemblies in packages right?

[leaden ice]

What does "apply" mean in this context?

And by "package" do you mean "assembly definitions"?

[wheat cargo]

I'm trying to use this source generator:

https://github.com/EngRajabi/Enum.Source.Generator

It generates an attribute, but it seems to be generating it for the default assembly and assemblies from other packages because I'm getting a type conflict on the attribute that it generates which is pointing to the package assembly

Assets\Behaviours\Systems\Input\Panels\DEPInput.cs(10,6): warning CS0436: The type 'EnumGeneratorAttribute' in 'Supernova.Enum.Generators\Supernova.Enum.Generators.EnumSourceGenerator\EnumGeneratorAttribute.g.cs' conflicts with the imported type 'EnumGeneratorAttribute' in 'AsyncImageLoader.Runtime, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'. Using the type defined in 'Supernova.Enum.Generators\Supernova.Enum.Generators.EnumSourceGenerator\EnumGeneratorAttribute.g.cs'.

What I mean by "apply" is that the source generator runs for that assembly

At this point, I may just fork it and manually define the attribute

[somber nacelle]

https://docs.unity3d.com/6000.0/Documentation/Manual/install-existing-analyzer.html

ny scripts that are within the same assembly definition as an analyzer are in that analyzer’s scope. For analyzers in the root level of the Assets folder, Unity considers all files in the project to be in scope

[wheat cargo]

Yeah I saw that, but didn't think it would apply to packages folder as well

I had to fork and modify the generator anyways, since it isn't configured for Unity

[north dove]

Im working on a project that is a 3d modeler kind of like inventor assembly, but with specified parts instead of making your own; like certain sizes of metals. One feature that my friends are trying to add is an ability to create custom parts. But these custom parts are only made with like a plastic sheet. so they are like 1/8 inch thickness but any shape you want on a plastic sheet. (image for example).

i feel like this has been done before and wondering if there is any documentation on it?
Another solution would be to have the user import .svg, .fbx. or .obj files but i havent found any ways to do that yet. If someone could help me with that it would be super appreciated.

[hexed pecan]

What are you asking though? 👀

Project seems cool

Are you asking how to implement the custom sheet?
And would players make the sheet ingame or in an external software?

[north dove]

so i have 2 options for it, either they make the sheet ingame, which really i just mean like they trace out some design they want and then it gets expanded into 3d but only 1/8 in long.
or the second option they can just import their own 3d model they made on like inventor or something

[north dove]

if you want to try the project you can download it here, https://github.com/BreadSoup/Protobot-Rebuilt/releases/tag/v1.3.5

[hexed pecan]

You could probably use a third party solution for importing 3D files at runtime.
For in game editing, I would make a simple UI editor that lets you draw lines, drag vertices etc. It's very much doable

[north dove]

okay, though ive tried looking for third party solutions and i just cant find anything. atleast not in runtime.

and for the in game editor, ill have to look into that, i havent experimented with stuff like that

[hexed pecan]

First one that I found, costs 20bucks though
https://assetstore.unity.com/packages/tools/modeling/trilib-2-model-loading-package-157548

Seems like it would work at runtime

You can always write your custom importer too if you want to.

[north dove]

hmm yea thats what we do a lot of the time, but like the scripting API is the difficult part.

i mean writing our own is better but does unity have that built in?

[cold parrot]

unity has a SVG importer (for 2D shapes) and importers for common 3D poly mesh formats, typically for runtime import you want to use gltf, paid and free import assets exist.

you likely want to be able to import shapes made with 3rd party tools that you only arrange in your unity tool.

[faint hornet]

why is this not working?

public static async Task LocalPosRoutine(Transform transform, AnimationCurve curve, Vector3 startPosition, Vector3 endPosition, float duration)
  {
    transform.localPosition = startPosition;
    transform.gameObject.SetActive(true);
    float et = 0;
    while (et < duration)
    {
      et += Time.deltaTime / duration;
      if (et > duration) { et = duration; }
      float eval = curve.Evaluate(et);
      transform.localPosition = Vector3.LerpUnclamped(startPosition, endPosition, eval);

      if (et >= duration)
      {
        transform.localPosition = endPosition;
        break;
      }
    }
    await Task.Yield();
  }```

[somber nacelle]

define "not working"
but at a guess, i'd say you're probably doing something like using Task.Run to start this which means it is scheduled to run on the threadpool which may not be the main thread, so when you try modifying a unity object the thread silently fails because you cannot use the majority of the unity API off of the main thread

[hexed pecan]

You are yielding outside the loop

So all of the while loop iterations happen at once

But yes, be explicit about what is not working

[faint hornet]

Im not using Task.run.

the function is running fine as a coroutine, but when i changed it to a task, the tranform is no longer interpolating.. instead it's just snapping to it's end position instantly

[somber nacelle]

also note that awaiting Task.Yield does not guarantee that it waits for the next frame. if you're on unity 6 you should be using the Awaitable class to await the next frame

[faint hornet]

how could this be a problem?

[somber nacelle]

if the system decides to continue execution multiple times per frame then you'll get more iterations of the loop than you'd expect. or if it doesn't continue execution for several frames then you'll get fewer iterations. and Time.deltaTime is not the difference in time since the last iteration, but the difference in time since the last frame so those extra long/short yields would end up with weird behavior

[faint hornet]

so what you said fixed it but now i'm getting some other weird snapping like it's not fully running the while loop but ending on the correct position.. this is the function that calls it.

  {
    List<Task> tasks = new List<Task>();
    int delay = (int)(iterationDelay * 1000f);
    foreach (var transf in diceComps)
    {
      Vector3 start = transf.transform.localPosition;
      Vector3 end = transf.transform.localPosition;
      start.y -= 500f;
      tasks.Add(TransformUtility.LocalPosRoutine(transf.transform, curveDiceMove, start, end, duration));
      await Task.Delay(delay);
    }

    await Task.WhenAll(tasks);
  }```

anything wrong with this function?

the iterationDelay can be any float i want it to be and works fine.. but the duration variable only works if it is set to 1 sec...?

[simple void]

You're adding all commands to 'move' as their own tasks without actually moving them within the loop. Then it does it all your "move commands" at once when you say Task.WhenAll(tasks). It doesn't actually move anything during your loop

[faint hornet]

but it's working as intended ? i'm confised by what you are saying

[simple void]

It moves it to the correct position in the end but doesn't move smoothly right?

[north dove]

Could you link a site for the 3D importers? Like the scripting api?

[faint hornet]

it moves smoothly at 1sec duration but anything less than that it snaps out early

[faint hornet]

I'm not really sure what you mean though.. ? i am running the localposRoutine in the loop and i have the delay set correctly?

[simple void]

That’s the thing tho you’re not running it you’re simply adding the delegate to a list

[faint hornet]

so instead of tasks.Add(TransformUtility.LocalPosRoutine(transf.transform, curveDiceMove, start, end, duration));
do this? Task t = TransformUtility.LocalPosRoutine(transf.transform, curveDiceMove, start, end, duration); tasks.Add(t);

[simple void]

No to run it you have to await the task or call task complete

I.e. await t

[faint hornet]

I don't want to wait until it's finished... i want to wait for the delay timing only

[simple void]

So you want to delay it then move the next component?

Right now none of your move commands are done until all the components have been delayed for

[faint hornet]

? the components are moving at the correct time they are supposed to move.. the issue is the Task is cutting out early for each one.. like it's clipping out early. lets reset for a second to make sure we are on the same page. do you understand what i'm saying now?

litterally the only issue that isn't behaving properly is when i adjust the "speed" at which this whole things happens.

[simple void]

No there’s a fundamental flaw in your code. When task.Add(awaitable task) is called it simply schedules it to be run at some point. It may be run right now or anytime in the future it’s up to the scheduler. When you call Task.WhenAll() it actually does the commands, but since this function is async it finishes at any time relative to the game loop

You want to call move directly not queue it to await at once

[faint hornet]

ok so i have a misunderstanding of how the task works...

[faint hornet]

how do i acheive what i want to without having to wait on each one indipendently to finish?

[simple void]

If your code works it’s simply a fluke and should not be relied upon

[faint hornet]

got it, ok so how do i acheive what i need to?

[simple void]

You want each component to wait an incrementally longer time? So like dice 1 waits 1 second and dice 2 waits 2 or do you want them all to wait 1 second and move?

[faint hornet]

i want the move animations to overlap.. so all of them are happening incrimentally but happening simutaneously for the bulk of their animation

[simple void]

Assuming localpositionroutine spends duration to move the input, the fix is to not add the extra delay

[faint hornet]

for example:
all dice have the same animation duration lets say 1sec.
but their is also a itteration offset delay. lets say its .5 sec.

dice one goes. wait .5 sec then send dice 2. when dice 2 starts, dice one will be half way done with its own animation.

[faint hornet]

i'm trying to create a pure function that i can use for other elements of my game. a function that serves multiple purposes, wether it's dice, or menu UI button animations etc.

[somber nacelle]

is there a particular reason you switched from using coroutines to using tasks for this? coroutines can do what you are attempting much more easily and are actually intended for time/frame specific waiting unlike tasks which aren't exactly suited for what you appear to want

[faint hornet]

coroutines are specific to monobehaviour scripts correct? i want my functions for this to be reusable in projects. so a couple of my functions are static, ones i will reuse for any project

[simple void]

Make a new async function like this
tasks.Add(async () => {await Task.Delay(delay); await TransformUtility.LocalPositionRoutine(…);})

Sorry I’m on a mobile device it’s really hard for me to type code

Then await all these tasks at then end using Task.WhenAll()

[somber nacelle]

you can do the exact same thing as a coroutine. it's just that a monobehaviour has to start the coroutine. that doesn't mean the coroutine method must be declared on that monobehaviour

[faint hornet]

doesn't this put a delay first also?

[simple void]

Just set delay to 0 in the first one

[faint hornet]

i understand that, but i need to call the coroutine outside of the monobehaviour.

[faint hornet]

so why can't i ad the delay at the top of my forloop?

[simple void]

You’re delaying when your movement is being added to the list not when it’s executed

[somber nacelle]

this is easily done too. but it seems you don't care and just want to use tasks. so good luck 🤷‍♂️

[faint hornet]

why are you saying i don't care? I'm coming here to ask for help. if what i'm saying is wrong, you have the choice to correct me, or stay out of the discussion. don't tell me i don't care.

[faint hornet]

why is their a double await? idk how tf you guys figure this out. this makes no sense to me

also it won't let me use the lambda function to make it

[simple void]

Sorry it’s an accident I’m typing on a phone in the rain 😭

[simple void]

Idk why not but u can make a local function u define inside ur function

async Task diceMove(){}

[somber nacelle]

it is trivial to just have a DDOL object with a MonoBehaviour on it that you've got a static reference to in order to start the coroutines

and you would get the benefit of actual proper frame timing instead of what i described earlier regarding Task.Yield.
or switching to using unity's Awaitable class (if you are on unity 6) would lead to better results with your current code

[faint hornet]

can i break this down a bit more.. idk why but i feel like i'm not understnding and their might be a miscomunication on my end.

this is what i'm trying to acheive, forget the animation stuff for now.

1. a coroutine to handle 1 single animation.
2. a coroutine that takes in an array of transforms and the a coroutine (the number 1.) and assign it to each transform with a delay between all of them. ex. (Transform[] transforms, Coroutine/Task routine/task, float iterationDelay)

[hexed pecan]

So you want to perform the same coroutine on several objects in a sequence

And be able to pass the coroutine into the second coroutine as an argument

[faint hornet]

exactly. but i want it to be a pure function that i can reuse in any project

my reasoning for wanting it this way to to be able to pass in new "animations"(coroutines) to the same function for different aspects of my game or multipe games

I've made this Coroutine function many many many times. and i'm tired of remaking it. so i figured Tasks are the only way to go since i can store it statically.

@hexed pecan

[hexed pecan]

Uhh there might be a better way of going about this but this is what came to mind...cs void Play() { Transform[] targets = ... StartCoroutine(AllAnimsCoroutine(targets, t => AnimCoroutine(t))); } IEnumerator AnimCoroutine(Transform t) { /* Do stuff */ yield break; } IEnumerator AllAnimsCoroutine(Transform[] targets, Func<Transform, IEnumerator> coroutineGetter) { foreach (var target in targets) { IEnumerator coroutine = coroutineGetter.Invoke(target); yield return StartCoroutine(coroutine); // Waits for the coroutine } }

So passing in a Func that gets the coroutine for that transform

Could be generic too instead of using just Transforms

[faint hornet]

so do this work in a way to make it static?

and how would i be able to have my game state waiting for all routines to end?

[somber nacelle]

that code, as written, could not be made static because it is calling StartCoroutine on this, but as i said before, it's incredibly trivial to just spawn an object that you slap a monobehaviour on to use for starting the coroutines

[hexed pecan]

I sometimes do use a singleton that runs coroutines that aren't attached to a particular gameobject

[faint hornet]

I'm trying really hard to make a clean setup for this since i use this type of thing often and in almost everyone of projects... there is not other way other than to create a singlton or DDOL object?

@hexed pecan

[hexed pecan]

If you use coroutines, you need a monobehaviour, that's it

[somber nacelle]

if you want to use a coroutine then you need a MonoBehaviour. that is not negotiable.
if you want to use async methods then you would ideally use unity's Awaitable over Tasks so you have the proper control over the execution timing that you want

[hexed pecan]

Btw you can make a singleton class that just instantiates a singleton instance when accessed, if it doesn't already exist

[faint hornet]

and btw, i don;t want people to think i'm just trying to get all the code written for me. i'm trying my best to understand this fundamentally so i can iapply this knowledeg to alot of other things in the future without having to ask for more help

[hexed pecan]

So you don't have to place it in the scene beforehand

[faint hornet]

i'm aware of how to make all this work the way you have been showing me. I'm just looking for a more scalable solution

[hexed pecan]

Need more specifics then

Maybe give an example code of how you would like to use it

[civic girder]

is there any guide about using namespaces to reduce domain reloading?

[fallen lotus]

Can anyone help me with this issue? I'm using tilemaps for the first time to layout the map. I have the red tiles set to have a collider and the blue one (top left) and green one (bottom right) to not have colliders. I'm trying to send raycast out to detect if the user hit a wall. however, I need to assign certain tiles a layermask. Right? How do I do this?

[somber nacelle]

yes, that guide would be: namespaces have no impact on domain reloading.

it is the number of static objects in each assembly that is being reloaded that determines the time domain reload takes. split your code up into different assemblies and only the ones that have changed will be reloaded

[somber nacelle]

this is not optimal, hasn't been tested, and was written in notepad++ so there may be issues, but theoretically should work for what you are trying to do (you'll obviously need to add the correct using directives, i was too lazy to do so)

https://paste.myst.rs/fp0w8328
it's based on what Osmal posted before, and even includes a callback for when all of the coroutines have completed. you can then build on this to do more than just start a bunch of coroutines in sequence

[spare dome]

would I create a class for projectiles that contains such variables and Booleans such as damage, isexplosive, speed, dropoff, etc and access them in the script of which instantiates the projectiles or would for a global bullet variables or is it a waste to do such and I would instead just include these in the class of which instantiates the projectiles?

[daring pine]

Guys i am using playerprefab to save data i want to save data for scene 1 when i go to scene 2 and when i come back to scene 1 it loads

how do i do that?

[cosmic rain]

This depends a lot on your project and context and even just preference.
If you have many bullet types that each weapon can use, I'd say have a separate data structure for it.

[daring pine]

everytime i try it doesnt worlk

[cosmic rain]

• save on scene exit
• load on scene entry
  As simple as that

[daring pine]

how do i write it

[cosmic rain]

You'll need to elaborate on that

[daring pine]

private void ???

[daring pine]

how do i write that

[cosmic rain]

You can see the api in the docs

[daring pine]

burh

ok

[cosmic rain]

You're not gonna get a complete solution here

At least show some effort

There are many resources online on how to do that.

[daring pine]

i acctually searched

and did

this is my last effore

i came here as a last choice

[spare dome]

preferably I would have different projectile types which includes but is not limited to isexplosive boolean and the radius, damage, duration that goes along with it (if true) and I would also have a damage, speed, dropoff, gravity, etc (if isexplosive is false), so maybe a separate data structure would be good to have

sorry for the lack of context

[cosmic rain]

Then share your setup and explain what didn't work. Ad well as how you debug it.

[cosmic rain]

Yeah, sounds like a separate script would be fitting. Maybe an SO.

[daring pine]

i use sometheing like that for close application and open application private void OnSceneUnloaded(Scene scene)
{
// Save the game data before leaving the scene
SaveGameData();

i want to use it for scene entry Load Scene exit Save

[cosmic rain]

You'll need to call that before you start loading a new scene. As for how and where exactly, that depends entirely on your project(and where you load scenes in code).

As for loading, you can do that in awake or on scene loaded callback.

[spare dome]

I have never really used SO's before, would they work roughly the same as making another class for the projectile?

[cosmic rain]

Yes. It's basically like a MonoBehaviour, but can live outside objects and scenes as an asset in the project.

[spare dome]

sweet

[cosmic rain]

So you can define many different bullets scenes with instances of the class.

[spare dome]

nice, I'll look into it, Thanks Dlich as always.

[faint hornet]

what does it mean by this ?

An object reference is required for the non-static field, method, or property 'CoroutineManager.Mono.StartRoutine(IEnumerator, Action)

[somber nacelle]

ah, it's probably because i named the property the same as the class, change one or the other

Mono isn't a good name for it anyway, so i'd recommend changing it to something more descriptive

[faint hornet]

is it because this Mono.StartRoutine should be named _mono.StartRoutine

[somber nacelle]

no, you need to use the property

[faint hornet]

this is throwing the error
Mono.StartRoutine(InSequence(objects, routineGetter, delay), onComplete);

[somber nacelle]

i am aware. and i've told you how to resolve that

[faint hornet]

i'm just not sure what part you are talking about... what is mono in "Mono.StartRoutine(InSequence(objects, routineGetter, delay), onComplete);" reffereing to?

[faint hornet]

the reff is private static Mono _mono; but i should change Mono class to something else?

[somber nacelle]

it should be the property, but as i've pointed out i named the property the same thing as the nested class so it's trying to use that directly instead

[somber nacelle]

again, you need to use the property, not the field.

are you just unaware of what a property is?

[faint hornet]

yeah what property are you talking about. it's not that i'm not listening to you, i just don't know what you are saying

[somber nacelle]

the one on line 4. did you just not read the code or what?

[faint hornet]

is Mono something that already exists in Unity boilerplate code or something?

[somber nacelle]

alright so you just copy/pasted the code without reading it. that's good to know

[faint hornet]

no i didn't actually, i read the code for 5 min trying to understand it. then i realized i have to go, so i copy and pasted it into my vscode. to look at later but their are a ton of errors. im just asking what's wrong with it

[somber nacelle]

and let me guess, those "ton of errors" are that one error and then a bunch of errors about missing a using directive because i already told you that i did not include those

i already told you how to resolve this issue though, but you didn't bother reading the code so do whatever you want with it 🤷‍♂️

[faint hornet]

bro, there wasn't a ton of errors. my bad, there were 3 and 3 or 4 missing directives. but anyways man. thanks for the help

have a great night. i gtg

[faint hornet]

i think line 4 you are reffereing to private static Mono Mono => EnsureMonoExists(); yeah i already changed that but there is still an error that you clearly aren't reading from my end.

[somber nacelle]

oh of course, i'm supposed to read your mind to know you've changed something?

[arctic steeple]

What is the different between update and fixedupdate, I was looking for how to implement addtorque and they say I should use fixedupdate instead of update, why ?

[somber nacelle]

Update runs every single frame. FixedUpdate runs at a fixed timestep that is in step with the physics engine. It is typically best to perform all physics operations inside of FixedUpdate so that those operations are performed along with physics updating and so they are performed on a fixed timestep

[arctic steeple]

Even with movement ? Should Transform.translate or transform.position be used in FixedUpdate ?

[somber nacelle]

neither of those use physics

in fact, if you want an object to interact with physics correctly you shouldn't use either of those and should instead use a rigidbody (or a character controller if you only want it to react to colliders in its movement path)

[arctic steeple]

Such as rigidbody addforce or velocity ?

[somber nacelle]

yes, both of those interact with physics

[arctic steeple]

And everything which use rigidbody is physics so I should put them in the fixed update ?

[spare dome]

all of the rigidbody methods yes

[arctic steeple]

Is it necessary to use time.deltatime in fixedupdate since they use physics based instead of framrate based ?

[somber nacelle]

it depends on what you are doing

[cosmic rain]

You don't particularly need to use delta time in fixed update, since it's always fixed. You can use it in some cases to standardize values, like speed, so that it's in per second space rather than per fixed frame.

[arctic steeple]

I was trying to get the ball moving like this, should I add time.deltatime ?

[somber nacelle]

no

[cosmic rain]

No, as you're assigning it to velocity.

[errant flame]

Hey , I am trying to manage my async processes with UniTask. In the UniTask tracker, the process is always pending, if I exit gameMode, only then it completes. I can't find anything to block the code.

Any idea ?

public static async UniTaskVoid LoadSceneAsync(int sceneIndex, Action<float> onProgress = null, Action onComplete = null, CancellationToken cancellationToken = default)
        {
            cancellationToken.ThrowIfCancellationRequested();
            AsyncOperation operation = SceneManager.LoadSceneAsync(sceneIndex);
            
            if (operation == null)
            {
                ELog.LogError("Scene Loader", $"Failed to start loading scene with index: {sceneIndex}");
                return;
            }
            operation.allowSceneActivation = false;
            try
            {
                while (operation.progress < 0.9f)
                {
                    cancellationToken.ThrowIfCancellationRequested();
                    Debug.Log($"Progress: {operation.progress}");
                    onProgress?.Invoke(operation.progress);
                    await UniTask.Yield(cancellationToken);
                }
                
                onProgress?.Invoke(1f);
                operation.allowSceneActivation = true;
                await UniTask.WaitUntil(() => operation.isDone, cancellationToken: cancellationToken);
                onComplete?.Invoke();
                ELog.LogInfo("Scene Loader", $"Successfully loaded scene with index: {sceneIndex}");
            }
            catch (OperationCanceledException)
            {
                ELog.LogWarning("Scene Loader", $"Scene loading cancelled for index: {sceneIndex}");
            }
            catch (Exception e)
            {
                ELog.LogException(e);
            }
        }

SceneLoader.LoadSceneAsync(1).Forget();

[cosmic rain]

What "processes" are you talking about?
