[spare dome]

please add 3 more ` at the end of your sentence

//code

[warm badger]

sorry

[spare dome]

dont be

you're fine

[ocean hollow]

so whats stopping you with this?

[warm badger]

the reference object in instantiating multiple times instead of only once

[spare dome]

well just making it a corountine doesnt automatically make it wait for a set amount of seconds

[warm badger]

i don't want it to wait actually, i just want that reference object to be instantiated only once when the player in inside the proximity

[soft shard]

Currently, your logic is going to start a new coroutine for every frame that dist <= distance, which will most likely be far more than just once, this could also be throwing off your testing

[warm badger]

exactly, but what could be the solution?

[spare dome]

make it wait a few seconds after it calls

[mossy snow]

your script needs to remember if it triggered or not. So give it a memory

[soft shard]

Yup, using a timer could be a good option, or a bool that the coroutine controls could be another option as well

[spare dome]

toggling a boolean could work

as well

[normal ingot]

What usually causes stack overflow in unity and how can i fix it?

Edit: I restarted the editor and my problem is gone : )

[lean sail]

usually infinite recursion

[vital hamlet]

how are MLAgenets so fast

what model do they use

[cosmic rain]

I don't think any model is included by default. You're supposed to train your own. Unless you're talking about something else.

[vital hamlet]

sorry i mean the training is really fast. When i try to make something like it (not for unity) its not even close to updating once per frame

im using keras

[cosmic rain]

It uses pytorch under the hood, so should be possible outside of unity.

[ember stag]

Hi everybody. Not sure if this is the correct channel for this, but I’m having an issue with switching quality level that causes Unity to crash. I have two scenes: a 3D scene and a 2D scene. The 3D scene is the main one. It seems if the game switches from the 3D scene to the 2D scene and I exit play mode, Unity crashes.

I attached screenshots of the errors.

I’ve got a ‘3D’ quality level and a ‘2D’ one.
Code:

    private IEnumerator TransitionToCardScene()
    {
        SaveGameState();

        QualitySettings.SetQualityLevel(cardSceneQualityIndex, false);
        SceneManager.LoadScene("CardScene", LoadSceneMode.Single);
        yield return null;
    }

        QualitySettings.SetQualityLevel(boardSceneQualityIndex, false);
        SceneManager.LoadScene("BoardScene", LoadSceneMode.Single);
        yield return null;

    private void ReturnToBoardScene(bool answeredCorrectly)
    {
        StartCoroutine(ReturnToBoardSceneCoroutine(answeredCorrectly));
    }

Any help would be much appreciated!

I’m using URP. Unity v2022.3

[cosmic rain]

Did you try googling the error?

[ember stag]

Yes, I couldn’t find any answers, though. I couldn’t find anything related to changing the quality level

I’ll keep trying to troubleshoot it, but if anyone has any idea on how to fix this, I’d really appreciate it

[cosmic rain]

What URP version are you using?

[cosmic rain]

And can you share the error details(stacktrace specifically)?

[ember stag]

I created my project with the Universal 2D v2.1.2 preset. The default URP asset file is used for the 2D quality. For the 3D quality I use URP_DungeonsLite.asset supplied with the asset pack for the 3D scene I’m using: https://assetstore.unity.com/packages/3d/environments/dungeons/low-poly-dungeons-lite-177937 It uses the supplied URP_DungeonsLite_Renderer.asset.

I’m guessing maybe Unity isn’t handling switching between these two very well. However, it only happens if I switch from the 3D scene to the 2D scene and exist play mode. If I exit play mode in the 3D scene, it doesn’t cause the crash or errors.

I’m not sure how to copy the stacktrace because whenever this happens, Unity crashes, and I have to force-quit.

In Quality settings, ‘2D’ uses the default URP file, and ‘3D’ uses the Low Poly Dungeons Lite URP file.

[cosmic rain]

I'm asking about the urp package version.

I’m not sure how to copy the stacktrace because whenever this happens, Unity crashes, and I have to force-quit.
Then how were you able to take a screenshot?
Regardless, you can get the stacktrace in the !logs

Dose anyone meet this problem? I post it just now, and need some solutions
https://discussions.unity.com/t/having-high-cpu-occupy-when-debugging-with-rider-after-finish-localizations/1520028

[ember stag]

Thank you.

URP 14.0.11, URP Config 14.0.10. Not sure how to check for the 3D one I got from the asset store.

Here’s the full error with stacktrace attached.

[cosmic rain]

There's no separation between 2d and 3d. 14.0.11 is the package version.

[ember stag]

Thanks for the help, and I hope I’ll be able to fix this. It’s likely just an editor issue, but IDK. I’ll try posting it on the Unity forums perhaps

It’s some issue with changing the quality level.

At least I believe so

[cosmic rain]

Looking at the stack trace, this is likely an issue unique to the editor only. And is probably related to the timing of changing the quality settings. Maybe try changing them after the scene is loaded and initialized.

[ember stag]

Okay, I’ll give that a try. Thank you!

[wary veldt]

Is there a way to specify fields required to be set in the inspector? To make unity warn or even prevent starting the game until you set the value

[soft shard]

You could maybe use OnValidate which will fire whenever the component changes, and I belive entering/exiting play mode - you could also use Awake or OnEnable to do checks in at runtime, otherwise youd probably need custom editor logic to do something like prevent play mode

[muted schooner]

Hi folk! I'm working on a project that is a kind of Vampire Survivors. I'm trying to optimize it to work with as much entities as possible - though I saw a strange performance leech in the profiler in Deep Profile mode.

public bool TargetInRange(out Vector2 direction, out float distance) {
        direction = YKUtility.GetDirection(ownedObject.transform.position, objectToFollow.transform.position);
        distance = Vector2.Distance(ownedObject.transform.position, objectToFollow.transform.position);
        return distance < reachDistance;
    }

have you got any idea about why this function is heavy? (400x entities, 22.7% total )

I think Unity is not caching transforms at all, and every time I call .transform it spends a lot of effort on it

should I just put the transform into a variable and let it consume RAM instead?

any information is appreciated and going to be helpful, thanks

[mossy snow]

you waste a lot of time fetching transform and position repeatedly. You waste more time on getting world position twice for each object, which is more expensive the deeper the transform hierarchy is. You waste a little time using distance instead of squared distance. You waste a bit of time casting Vector3 to Vector2 twice. This could be a good candidate to jobify btw, look at TransformAccessArray

[muted schooner]

that was useful, thanks! I'll give a look at c# jobs, looks like a good idea

[muted schooner]

to 300x entities, 10.2% total just by removing the unnecessary casting and duplication

[cosmic rain]

using squareMagnitude instead of Distance, should give a considerable boost imho

[muted schooner]

I'll give it a shot, though it turns out the main problem was that my RareTick was getting triggered EACH tick..

I was wondering why the AI movement was so smooth.. lol

[maiden fractal]

The final performance on build might also be much better on build compared to editor especially if IL2CPP is used

[muted schooner]

yeah definitely.. also deep profiling approximately halves the performance

[gray mural]

Having an array, what is the best way to initialize it without an error thrown?

[SerializeField, HideInInspector] private Object[] _undoObjects;

// Awake
_undoObjects = new Object[]
{
    gameObject,
    numberText.gameObject,
    difficultyText.gameObject
};

[cosmic rain]

What kind of error are you getting?

[gray mural]

NullReferenceException, since the array is null

[cosmic rain]

Where is it thrown? Share the stack trace.

[gray mural]

You're right. I'm ashamed, since that's texts that are null and they are on the same line as undoObjects. Thank you for your help

[jolly pelican]

hey, could anyone help with accessing the new input system within a state machine? i want to assign a different function to an input action based on the player state and i'm not sure how to go about it

[vagrant agate]

Try asking in #🖱️┃input-system. My first thought is creating action maps for those states and switch them when needed.

[jolly pelican]

will do, thanks!

[woven dome]

hi there
does anybody know why animator.SetFloat("Speed", value); wouldn't work (resulting in animator.GetFloat("Speed") = 0) even though "Speed" is guaranteed to be in the animator?

[cosmic rain]

Perhaps something else is resetting it.

[rigid island]

https://docs.unity3d.com/ScriptReference/Animator.SetFloat.html
because it does not have such signature or default value

[woven dome]

corrected

[cosmic rain]

Assuming you're actually using the correct signature. Otherwise there would be a compile error.

[rigid island]

Ahh i see edit now 👍

how did you verify what value is ?

[woven dome]

logging, just before

[rigid island]

could be something setting it right after

we would prob need to see full script

[woven dome]

animator.SetFloat ( AnimatorParams.Speed, _rigidbody.velocity.magnitude );
Debug.Log ($"velocity: {_rigidbody.velocity}, magnitude: {_rigidbody.velocity.magnitude}, prop: {animator.GetFloat ( AnimatorParams.Speed )}" );

this shows prop: 0

[pearl burrow]

Hi. If i have OnApplicationPause() on many script, is the execution order dictated by the settings i've set in the engine?

i cant seems to find an answer anywhere on the docs or over the web

[cosmic rain]

Does it show velocity as not 0? And where do you assign the animator?

[cosmic rain]

Should be. All of the messages are dictated by the execution order.

[rigid island]

oh didnt see it myb

[woven dome]

there is only one, and I do in the sample above

[woven dome]

yes and in the same script, serialized variable

[cosmic rain]

Okay. Can you confirm that the parameter doesn't change in the animator tab either?

[pearl burrow]

also for applicationQuit?

ill give a try

[cosmic rain]

Test it and see for yourself

[pearl burrow]

ok i tried with OnApplicationQuit() and it didnt work

[hexed sorrel]

I'm trying to make something where light from an event travels outwards in a sphere and can be detected by various detectors; my idea is to give the light from the event a trigger sphere collider with an expanding radius, and then when it touches the detector's collider the detector does something. But I'm wondering if there's a better way to do it - there may be lots of detectors and I don't want them checking collisions with one another or similar

[woven dome]

yes

[cosmic rain]

Take a screenshot of the parameter in the animator

[cosmic rain]

Get all the detectors in the range of your "light". Then filter out by the angle/dot product.

[elfin tree]

How can I make a vertical layout group put the elements above (bottom to top) instead of the usual top to bottom?

[cosmic rain]

Don't crosspost.

[paper tree]

Is there in unity / C# any common patter of storing safe/encrypted data localy?

[cosmic rain]

Writing to a file. Wether it's binary or text. But no matter how you encrypt it, it's not gonna be entirely safe.

[paper tree]

Sure, i just try to rewrite my storing data for game from XML to somehow secured like encryption JSON

The main goal is to prevent easy editing like text files or coppy from 1 device to another and run app with copied/ stealed data (they are not sensitive datas like Rodo or passwords etc... just some game saves)

[opaque vortex]

I am writing the code for my game, and I am working with protobuf to transfer data. Should I keep trying to learn protobuf despite my issues with it, or go for easier JSON for now?

I will end up needing to use protobuf in the finished project, the amount of byte data and other user related information will give me no choice in my finished project.

[carmine osprey]

Does anyone know how to fix my pitch? when it gets too high it sounds wrong. I have a audio clip for each note in the 4th octive. It could also just be my audioclips that sound wierd

    public void PlayNoteClip(int octave, int note, int velocity)
    {
        if (note < 0 || note >= keys.Length)
        {
            Debug.LogWarning("Invalid note index: " + note);
            return;
        }
        var obj = GameObject.Instantiate(keys[note].gameObject);
        obj.transform.position = new Vector3(0, 0, 0);
        var audio = obj.GetComponent<AudioSource>();
        audio.volume = velocity / 127f;
        audio.pitch = Mathf.Pow(2, (octave - 4));
        audio.Play();
        if (!obj.activeSelf) { return; }
        GameObject.Destroy(obj, audio.clip.length);
    }

[oblique spoke]

Backing up and transferring save data is a pretty standard feature on platforms nowadays, so I would avoid trying to lock things down to a device. Simple edits can be prevented by using a binary format with the added benefit of most likely making things a bit more efficient across the board.

[paper tree]

but isn't in reverse it unsafe to read binary code as it may be attacked from 3'rd party programs

[oblique spoke]

I believe it comes more down to deserializer design (and how you use it) than the format.

[paper tree]

Yeah i readed that decoding binary data can be executed as well so its not good idea at all to use it from local files

[simple egret]

The vulnerability comes with BinaryFormatter, if you are not using that, you should be safe

There are other binary serializers, and if you want to roll your own file format, there's BinaryReader and BinaryWriter

[oblique spoke]

Though you should be aware of the potential consequences of having code that deserializes any types, which most deserializers can be configured to do.

[winged sphinx]

Is there any way to open a second window in an application?

[outer plinth]

Hey, i am struggling with this particular Orientation problem, I want the character's Up and Forward axis to return to normal but also apply the additional rotation, this code seems to do this but the additionalRotation is applied in the wrong direction

https://cdn.discordapp.com/attachments/763495187787677697/1284137133531070515/2024-09-13_14-02-03.mov?ex=66e82c66&is=66e6dae6&hm=e5d816e3c9871f7fac348a4c13cec7ecea5dc4d18f95628d572e14af50d6bb9e&

(https://pastebin.com/Nkj3GX4x)

Is there a better way to combine those two FromToRotations and another quaternion?

And/or is there a standard practice for combining more than 2 Quaternions that I am missing?

[swift falcon]

then can you suggest something to me when you consider how the Gameobject in question is followed by a Cinemachine?

[mellow sigil]

I haven't done anything like that with Cinemachine. You might want to ask in #🎥┃cinemachine about it

[winged sphinx]

Essentially I want to have different displays appearing in different windows. I'm trying to set up a player side and game master view using multiple monitors. That could probably be done with networking but that would be way more complicated if I'm running it all on the same machine.

[oblique spoke]

You can invoke platform specific APIs to create new windows. Rendering Unity elements on multiple windows might be complicated.

[knotty sun]

just use 2 cameras each set to a different display

[oblique spoke]

Oh, right, Unity does have multi display support https://docs.unity3d.com/Manual/MultiDisplay.html

[woven dome]

animator.SetFloat ( AnimatorParams.Speed, _rigidbody.velocity.magnitude );
Debug.Log (
    $"velocity: {_rigidbody.velocity}, " +
    $"magnitude: {_rigidbody.velocity.magnitude}, " +
    $"prop: {animator.GetFloat ( AnimatorParams.Speed )}"
);

private static class AnimatorParams {
   public static readonly int Speed = Animator.StringToHash ( "Speed" );
}

[elfin tree]

How come this code directly modifies the prefab, even if it seems properly instantiated?

 [SerializeField] private DirectoryData rootDirectory;
        [SerializeField] private GameObject buildMenuElementAsset;

        private BuildMenuFolderController _rootElement;
        
        public void Start() {
            var folderGo = Instantiate(buildMenuElementAsset);
            _rootElement = folderGo.GetComponent<BuildMenuFolderController>();
            _rootElement.transform.SetParent(transform);
            _rootElement.InitializeRootFolder();
            
            BuildFolders();
            //PopulateFolders();
        }

(...)

        public void InitializeRootFolder() {
            Debug.Log("[Build Menu] Initializing Root Folder...");
            _isAlwaysExpanded = true;
            _expandDirection = ExpandDirection.RIGHT;
           
            InitializeExpansion();
            
            gameObject.name = "Directory - Root (Folder)";
            _layoutGroup.transform.localPosition = Vector3.zero;
            _layoutGroup.gameObject.name = "Directory - Root (Content)";
            _layoutGroup.gameObject.SetActive(true);
        }

[inner shuttle]

instead of using a new Vector3 is there a more efficient way of altering one axis like this?

playerCam.transform.localPosition = new Vector3(0, 0.1f, 0);

[worn crystal]

create an extension method maybe

[inner shuttle]

oh yeah i suppose

[simple egret]

(this does not alter one axis btw, it reassigns a whole new vector)

[inner shuttle]

localPosition.y?

to alter 1

[simple egret]

Altering one axis would be:

Vector3 v = playerCam.transform.localPosition;
v.y = 0.1f;
playerCam.transform.localPosition = v;

[inner shuttle]

alright cheers 👍

[west lotus]

But to answer your question, no there is not a more efficient way since vector is a value type

But it’s pretty efficient to allocate new ones

[gray mural]

And since it's a property

[rigid island]

btw if you actually tried doing that you get infamous https://unity.huh.how/compiler-errors/cs1612

[inner shuttle]

oh lol okay thanks

[elfin tree]

I think it might be because my prefab has a reference to itself (editor field) and it doesn't actually take the default prefab, it takes itself when instantiating

yeah, it was that

what a weird behavior

[deep stirrup]

Is it possible to detect when Character Controller uses step offset to climb the surface?

[rigid island]

not likely as that happens C++ side

[deep stirrup]

😦

[rigid island]

yeah, and its prob physxs implementation https://docs.nvidia.com/gameworks/content/gameworkslibrary/physx/guide/Manual/CharacterControllers.html

[deep stirrup]

🙁

[elfin tree]

What's the best way to extend the "hitbox" of a ui element?

[rigid island]

depends on that shape ig.
maybe put a custom sprite above/under it with like 0 opacity

[elfin tree]

mb meant to reply to my own thing, turns out you can use negative raycast padding on any image, and most buttons usually have an image somewhere

negative means outwards for some reason

[rigid island]

oh for square ig is easier?

I was wondering if the image component at 0 opacity would still work with alphaHitTestMinimumThreshold
since it states it grabs it from the actual sprite texture and not the renderer
(I guess ill just testit)

[rigid island]

yeah I was thinking of a different shape than square 👍

good enuf 😅

[elfin tree]

ohh, yeah if you have a more complex shape

and 0 opacity idk, i think i needed to use 1 opacity once

but i'm not sure if iirc

but yeah you can probably use alphahittest to fix that

lmk if u end up testing it

[rigid island]

will do!

[rigid island]

yeah even with Image alpha color to 0 opacity alphahittest still works, its getting the alpha values from original texture

so you can technically have invisible images any shape you want above it as hitbox to trigger whatever you want

[swift falcon]

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

        var rb = GetComponent<Rigidbody>();
        rb.velocity = transform.forward * flySpeed;
        Destroy(gameObject, flyTime);
    }
}

Error:Skipped updating the transform of this Rigidbody because its components are infinite. Could you have applied infinite forces, acceleration or set huge velocity?

void ShootPlayer()
    {
        Instantiate(bulletPrefab);
    }

Getting this error when bullet gets instantiated onto the scene

[rigid island]

its telling you exactly whats wrong

Could you have applied infinite forces, acceleration or set huge velocity?

also check colliders when spwaned, make sure its not stuck somewhere or huge

[swift falcon]

Forgot to say that I'm not applying an infinite force, acceleration or huge velocity. I'm only doing this rb.velocity = transform.forward * flySpeed;

[rigid island]

I see that

the computer says otherwise though, I tend to trust the results of the computer

have you tried debugging the values before passing to it ?

[swift falcon]

I'll try to. When it's an error like this I tend not to trust unity at all

[rigid island]

var myVel = transform.forward * flySpeed;
rb.velocity = myVel
Debug.Log($"{this} myVel is {myVel} and current rb.vel is {rb.velocity} ")

[rigid island]

there are checks in place for a reason, the calculator is 99% never wrong

when things dont work as expected is *usually * the users fault somewhere, not the computer

[lean sail]

The only errors you can really treat like this are editor ones unrelated to your code. Unity is quite clear on telling you what's happening here.
Check the inspector for the prefab, it's possible you assigned it a large value somewhere there even

[swift falcon]

no that's not the case there are no large values assigned on my end

[rigid island]

what you see here is not whats happening in the game so 🤷‍♂️

also where is the collider

[swift falcon]

it's a sphere collider

[rigid island]

lol where not what

[swift falcon]

idk what you mean by where but it's on the bullet

Edit: I was being stupid I forgot to destroy the game object after it collided

[rigid island]

I meant where is the component cause it wasnt on the gameobject inspector you showed

[swift falcon]

ik i didn't show the full game object

[rigid island]

anyway I would suggest debug the runtime values

see whats actually happening in playmode

[inner shuttle]

learning wise, whats the best way of actually getting something out of tutorial code? i thought of commenting it for what i knew but i dont know if thatll make anything stick

[storm wolf]

Hey quick question on if I am doing this right...

//add crafted item to inventory
InvItemData cloneItemData = GameObject.Instantiate(recipe.result);
Inventory.AddItem(cloneItemData);

Would something like this work with scriptable objects? I am instantiating a copy of the SO before saving it for later is this correctly how to do this? Will this mess with the original at all?

[mighty void]

exists a channel for profiler theme?

[quaint rock]

its fine you can instance it and have data changes to the instance not effect the orginal

[storm wolf]

perfect thanks

[quaint rock]

i do it all over my code base, got a asset that represents defaults of something or inputs then i make in memory instances to work on

[storm wolf]

yeah lol i had the same thoughts

[mighty void]

i dont know why my fixed update takes 120 ms :T

[quaint rock]

would just keep in mind the instances act like other unity object stuff so you do need to manually destroy them when done with them

[storm wolf]

gotcha

[proven scroll]

Can someone help me with figuring out how to pause a time line while using a dialogue box so it only continues after they hit the next button on the dialogue box please

[mighty void]

use events

[quaint rock]

should be just a matter of adjusting Time.timeScale as needed and using events to handle anything else that needs to know about it

[mighty void]

IpointerEventHandler, OnPointerClick works fine

just stop the application and continues when the player clicks the dialogue box

[proven scroll]

ima little unsure as to where i would put this code and exactly how, ill send my dialogue box scripts

or would i just make a whole new script for this?

[mighty void]

make a new script

[mighty void]

so you can do it or

make it works with your custom event

[proven scroll]

Okay so make a new script called (PauseTimeline)
i would need a reference to the timeline gameobject and the dialogur box object?

[mighty void]

:T are you serious?

make a new script, call it whatever you want

implements IPointerEvents

[proven scroll]

im sorry im new to coding and very unsure on how to do this.. :/

[mighty void]

dont worry

implements PointerEvents

when you show your dialogue box stop the timeline

in that script where you show your dialogue box stop the timeline

in this new script, you have to implements ipointervents

and restart or continue your timeline

you dont need any reference :T

[proven scroll]

Okay
When try to implement IpointerEvent just keeps red line, i know i need a function for it right?

[somber nacelle]

yes, you need to implement the interface's members. you can also use the quick actions to do it automatically

[proven scroll]

when i do that theres like a bunch of functions it makes

Do I need all of these?

[quaint rock]

you sure you want IPointerEvent

assuming you want like IPointerClickHandler or something else

[proven scroll]

So just this then?

[quaint rock]

yeah

then do what ever you need to do in the OnPointerClick method

[mighty void]

you have to check if you want what click is

[proven scroll]

Would I just use an IEnumarator with the waitforseconds?

[mighty void]

using IPointerDownHandler, IPointerUpHandler you can check if you want specific clicks

right click, left click, middle click

[mighty void]

why do you wanna do that?

[proven scroll]

nvm guess that wouldnt do cause it would just waitfor some seconds then continue,

Honestly I havent no clue what to put here.... ngl 😦

[mighty void]

do you wanna wait seconds and wait for the player click?

or continue the game in the next seconds when the player makes click?

[proven scroll]

I want it to pause the time but still have players idle animation playing, but dont want the timeline to keep going unitil the dialogue box is closed

I thought it stayed on but it only stayed because the timeline time was over

I wanna wait seconds and wait for the player click through th edialogue then continue after dialogue is over

[ruby dirge]

Hello i don't know if this is the right channel to post this in but im trying to setup Vivox and when im reading the docs they say that i need a Dedicated server to authorize the access token for the users?

becuse my game is going to use p2p

[mighty void]

i'm not sure if you can run a couritine when the application is stopped

[proven scroll]

so it would have to go by counting the clicks?

Trying to get a NavMeshAgent to take knockback, but it won't leave the NavMesh area. How do I get the NavMeshAgent to stop sticking to it?

[rigid island]

disable the navmesh agent while knocking back

it takes over your transform

[golden garnet]

👌

[lean sail]

Consider just using navmesh to calculate its path and move it yourself, via rb or any other way, if you want to have unique ways of movement

[cosmic rain]

Make sure you don't have spaces or invisible characters in the parameter name.

Loading issue inventory system

[plucky inlet]

Hey everyone, I am currently trying to get the locationservice to work properly in unity 6 and on ios/editor/visionos. Somehow, everytime I start the locationservice like in the sample method here, its just crashing the app/unity editor

        private async Awaitable VisionOSLocation()
        {
            locationService.Start();

            Dispatcher.Enqueue(() => Debug.Log($"Status: " + locationService.status, Instance));
            await Awaitable.MainThreadAsync();

            await Task.Delay(10000);

            Dispatcher.Enqueue(() => Debug.Log($"Status: " + locationService.status, Instance));
            await Awaitable.MainThreadAsync();
        }

The error happens right after start() firing Status.initializing on the next line

[thick terrace]

what sample method are you referring to and is the Dispatcher part of it? i don't recognize that and those MainThreadAsync are kind of weird

if you're expecting the function passed to Enqueue to be called from a different thread, you probably don't want to be passing in a unity object as the context for the log message

[plucky inlet]

Nah, its just to run the awaitable on background but still wait for the mainthread to get unity callbacks in correct order. But I think from what I read in the latest forums, the new input system still does not support location services at all and I have to use both input systems to get the location service running... trying on the AVP right now to double check.

[thick terrace]

are you calling this method from the main thread? again, probably not causing a crash, but i think at least one of those MainThreadAsync calls is doing nothing

[plucky inlet]

It is waiting for the mainthread but its being called from another backgroundthread

[thick terrace]

shouldn't LocationService.Start() be called from the main thread since it's a unity API?

[plucky inlet]

Usually I get an error on xcode when it should, but I also tested the start thing to be sure, its not the issue

[plucky inlet]

So starting from a background thread seems to kill it 100%. Starting it off the mainthread keeps the system running but its still stuck on initializing. If anyone had similar experiences with locationservices on mobile, let me know.

[runic linden]

If I have a function bool HasFoo() then you'd expect that function to check if foo exists. Is there a convention for "look for foo and create it if it does not exist yet"?

[lean sail]

When u say convention, do you just mean the name of the function? I'd probably go with like FindOrCreateFoo() or GetOrCreate maybe

[runic linden]

Yes thats what I ment

[gray mural]

bool CreateFooIfNotFound();
bool CreateFooIfAbsent():
bool CreateFooIfLacking();
bool CreateFooIfMissing();
bool CreateFooIfNotPresent();

You might take the following methods into a consideration, but since they are pretty long, I would consider simplifying it with Try at the beginning:

/// <summary>
/// Creates foo if not found
/// </summary>
/// <returns>
/// True if foo is found
/// </returns>
bool TryCreateFoo();

[runic linden]

I tend to write out whole sentences sometimes trying to describe the function and was hoping that for this case some kind of convention exists. This is something that is needed regularly so I was hoping for some sort of standard. 😅 Probably overthinking this anyways lol.

Thank you both

[compact perch]

chatGPT can help with following naming conventions ;p

[gray mural]

This is generally a great and fast approach

[stoic sluice]

Has anyone tried using Steam's auto cloud feature for saving game data?

I'm scratching my head at what I'm doing wrong causing it to not sync files.

[runic linden]

T UpdateField<T>(string[] guid)
{
  if(guid.Length > 0)
  {
    string path = AssetDatabase.GUIDToAssetPath(guid[0]);
    return AssetDatabase.LoadAssetAtPath<T>(path);
  }
  else
  {
    return default(T);
  }
}```
How do I make this work? The compiler throws an error for return `AssetDatabase.LoadAssetAtPath<T>(path)` because just writing T there is not allowed. typeof(T) does also not work.

[stoic sluice]

You'll need to specify the type constraint probably

[knotty sun]

return AssetDatabase.LoadAssetAtPath<T>(path) as T;

[stoic sluice]

Best to supply the compiler error

[runic linden]

https://learn.microsoft.com/en-us/dotnet/csharp/misc/cs0314?f1url=%3FappId%3Droslyn%26k%3Dk(CS0314)

The type 'type1' cannot be used as type parameter 'name' in the generic type or method 'name'. There is no boxing conversion or type parameter conversion from 'type1' to 'type2'.

When a generic type uses a type parameter that is constrained, the new class must also satisfy those same constraints.

[gray mural]

You haven't specified that T is a UnityEngine.Object

The method has to be modified as followed:

T UpdateField<T>(string[] guid) where T : UnityEngine.Object

[runic linden]

Thats it, thanks!

[gray mural]

Make sure to always check the generic argument when using the method

[runic linden]

Not sure what you mean.

[gray mural]

Make sure you always check the type of the generic argument, which, in your case, was UnityEngine.Object

[runic linden]

You mean in the declaration of the method or before calling it in code?

[gray mural]

I mean hovering the method or entering its script

[lost night]

I have a very specific problem: I want my player rigidbody object to not get pushed by specific rigidbody objects, but be able to be pushed by specific others. At first I used an kinematic rigidbody but that does not do the trick, as I now want to introduce an object that can push the player. (If you answer please ping me) thanks for any help

[knotty sun]

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

[somber nacelle]

if you want those objects to still collide but not affect each other but still be affected by other objects, then it is something that is kind of complicated. I know someone made an asset that can handle that for you, or you can ask them how they did it or even ask in #⚛️┃physics about how you could potentially set up interactions like that.
Here's that asset: https://discord.com/channels/489222168727519232/1247284826835517450

Thanks for the help! I now went with setting the mass of the I objects that should not push the player to 0 so they still push but with 0 force

[frigid turtle]

Hey guys, i face a weird thing with addressables. I add reference of a texture in a scene. Both texture and scene are part of a remote bundle. So they shouldn't be inside of a build. But build size is increased by 1Mb.

[sudden lantern]

Hi everyone. Does anyone know how to make the camera follow the player's movement direction? Like here in the video. Please don't say "use Cinemachine", I want to make my own fully controllable camera system. Thanks
(also for some reason the video doesn't load in Discord, so download it to watch)

[leaden ice]

You can make a fully controllable camera system with Cinemachine

[vagrant blade]

You should have some idea how you want to achieve if it, if you're so against using the proper method of doing this.

Such as, getting a point that is behind/above the player's facing direction (using some simple vector math) and then slerping the position of the camera to it.

[leaden ice]

But yeah it's just some relatively straightforward vector arithmetic

[fading umbra]

I need help with my weapon system, using new input system with invoke method and when I keep my mouse button pressed it wont shoot continuously only once. I use Action and invoke them by subscribing from another script. It seems fine but doesn't work as intended.

[vagrant blade]

The input system only tells you when something has been pressed, not held. You have to manage that yourself with a bool.

[violet nymph]

I'm pretty sure there is a way to do that without custom bools, the "GetKey" works on held for keyboard keys, so i'm sure there is something for the mouse too

[indigo tree]

If you don’t want it to use bools can have a coroutine that starts when you press it and stops when you release it lol

[fading umbra]

oh...any place where I can see how I can use it

[rancid frost]

I am manually creating shapes (in this case hexes) and using shaders to color them inorder to create textures.
What are some things I can do to make the map seamless? I want to remove the shape(hex) outlines

[leaden ice]

If you want to remove the hex outlines why start with hexes in the first place?

It owuld be easier to make a square tiling texture

[rancid frost]

That is a good point, But I need the shape (could be square or hex or triangle) because I need to be sure of the specific biome/data of that specific location

[modern creek]

Neat idea, tbh. I'd look into perlin noise and see if you can adapt it for hexes. It won't be easy, though.

[rancid frost]

thats not the problem, I have already done that

[modern creek]

What, perlin noise?

[rancid frost]

the problem is removing the hex outline from the map

[modern creek]

Your perlin noise generator will have to account for the coordinate of each tile, however - like, instead of a perlin noise function that's constrained to one hex, you'll have to broaden it so that any given pixel in the entire world belongs to the same contiguous noise function

[rancid frost]

ahh, I see

[modern creek]

Like I said.. it's not gonna be easy but I think it should be possible since the noise method doesn't really care how big/small the surface is.. but your coefficients will have to be a lot smaller and you might run into issues with floats on the shader if your world is large

alternatively you could lean into it and make your hexes have borders - like PB said, if you're just intending to make a smooth texture, you may as well use square based grids since .. you're trying to obscure the borders anyway, and the math'll be a lot easier

[rancid frost]

Right now, im doing something similar to that, but I think the problem is that thesame constant value is used to seed the noise

[modern creek]

yeah I dunno if I have the brain capacity to figure this out but I imagine you're going to need to have to calculate your noise value with a constant for "this tile" (id?) along with a constant for each of the adjacent tiles - such that the border along each of the 6 edges matches the inverted border of the adjacent hex

but I'm really shooting from the hip here.. that sounds hard

if you're looking for a smooth texture and using perlin noise, I'd probably just make a single square (or hex) and muck with the coefficients until you have a noise value that looks nice for the scale you're operating in

[rancid frost]

I see

The goal of this project is to create a realistic texture free map

[knotty sun]

#archived-shaders

[modern creek]

hm.. yeah.. it's an interesting problem tbh

[rancid frost]

apologize 😦

[modern creek]

like I'm assuming you want something like this: https://www.reddit.com/r/proceduralgeneration/comments/majq3b/made_a_perlin_noise_based_hexagon_world/#lightbox

but with each individual hex to not be obviously a hex

[rancid frost]

indeed and not 3d 🙂

[modern creek]

perlin noise for the hex type (at the world scale) and then perlin noise for the texture (at the hex scale)

[rancid frost]

lol, yea

at the texture scale, perlin noise is used,but its not seamless

I dont know why

[modern creek]

yeah I think you're gonna need to dream up a solution for making a perlin noise function for the texture of an individual hex have the world location as part of the input so that the textures between hexes is seamless

it's a pretty hard problem (to do in shaders) tbh - i think even if you get it working the issue is going to be float instability because your textures are gonna need to be so small (for a float, relative to your world size) that as you start getting far away from the origin your textures are gonna look more and more pixelated as the floats start resolving/rounding to the same number

[rancid frost]

its getting better....

[modern creek]

you did that just by feeding in the coordinate of the hex instead of the constant?

[rancid frost]

yea, the world pos. but.... let me just send small clip

sorry steven, let this one sldie please

It seems the random range is inverted...

[modern creek]

Hm.. I think you're on the right track but unfortunately it's been a few years since I've done anything with perlin noise - like I said I don't think I have the brain capacity to solve this one

but I think basically you need each vertex of adjacent hexes to have the same value and function along the edge.. as far as how, that's above my pay grade 🙂

[rancid frost]

Your idea works, from this point i just have to tweak it among other things.
Thanks for the help!

[modern creek]

I have a mesh that I'm adding a material to (at runtime) to outline it and render it through world geometry. The mesh is in a layer higher than world geometry, and I'm creating a local copy of the material and adding it to the mesh like so:

        [SerializeField] protected SkinnedMeshRenderer OutlinedMesh;
        [SerializeField] protected Material OutlineMaterial;
        protected Material _localOutlineMaterial;
        public void Initialize()
        {
            _localOutlineMaterial = new Material(OutlineMaterial);
            List<Material> mats = OutlinedMesh.materials.ToList();
            mats.Add(_localOutlineMaterial);
            OutlinedMesh.materials = mats.ToArray();
        }

It looks like it works, but when I set the color of this local material using the following, the part that "sees through" the world geometry uses the default color:

        public void SetOutline(Color color)
        {
            _localOutlineMaterial.SetColor("_Outline_Color", color);
        }

In the following shot, the default color is cyan, and the new color is red.

Why?

[untold crystal]

i cant see the gizmos like the camera sqare thing in the scence that tells you what you see in game please help

[leaden ice]

Did you try turning on gizmos?

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

[worn star]

how do i make something go forward in the direction of its rotation

like if i spawn it rotated by 45 degrees it moves in that direction rather than horizontally

for 2d

[dusk apex]

If you keep a local copy of the materials array and assign the entire array back using the materials property, does it differ? For examplecs _localMaterial = ... _local Materials = ...ToList(); ...Add(...); ...materials = ...ToArray();``````cs _localMaterial.SetColor(...); ...materials = ...ToArray();

[modern creek]

I haven't tried that but I will.. I'm thinking it's something with meshes not updating materials and that I have to use MaterialPropertyBlock?

ie: the code snippet https://docs.unity3d.com/ScriptReference/MaterialPropertyBlock.html

[worn star]

nvm fixed

[modern creek]

yeah that fixed it (setting property block)

[dusk apex]

I'm assuming that modifying a material copied to materials will not affect the copies.

[leaden ice]

transform.right or transform.up is the direction it is facing. Have your code move it in that direction.

[worn star]

yeah fixed

thanks tho

[modern creek]

yeah.. I don't know exactly how meshes determine that a material needs to be re-rendered, I would have assumed changing shader properties on a material would do so, but apparently not

(ignore the blue gun - but now setting the property to red using propertyblock instead of on the material directly works)

basically changing this to this:

        public void SetOutline(Color color)
        {
            _localOutlineMaterial.SetColor("_Outline_Color", color);
        }

        public void SetOutline(Color color)
        {
            MaterialPropertyBlock propertyBlock = new MaterialPropertyBlock();
            propertyBlock.SetColor("_Outline_Color", color);
            OutlinedMesh.SetPropertyBlock(propertyBlock);
        }

I don't know exactly why.. I'm still a little hazy on how materials work under the hood

[tacit vine]

So i have a namespace what unity cant find.
I added all the DLL's and the strange thing is visual studio says that he can find the namespace but why cant unity do this?
i added the packages with the visual studio add references

[dawn nebula]

I have a value in the range of 0 and 1. This value is my target. It jumps around in this range quickly, I would like to smooth out its motion, where we accelerate towards it the farther away we are, and slow down upon approach. Any built in functions to help with that?

[vagrant blade]

Mathf.MoveTowards(...)

If you want it to slow down, you can use Mathf.Lerp(...)

https://docs.unity3d.com/ScriptReference/Mathf.Lerp.html

Note that using lerp means it will never reach the target exactly, you will have to check that the value is approximately close enough.

Alternatively, you can get a tweening library (DoTween, PrimeTween, etc.) and use that to do it for you.

[dawn nebula]

Oh would I have the delta scale based on the value between current and target?

[vagrant blade]

MoveTowards will keep the speed consistent until it reaches the value

[dawn nebula]

Right but I don't actually want that.

        currentZoomRange = Mathf.Clamp01(currentZoomRange + delta);
        var approachScaler = Mathf.Abs(currentZoomRange - currentSmoothedZoomRange);
        currentSmoothedZoomRange = Mathf.MoveTowards(currentSmoothedZoomRange, currentZoomRange, Time.deltaTime * approachScaler);

[vagrant blade]

Lerp will slow down as it gets closer, but honestly would just use the tweening library and use an EaseOut curve (or whichever curve makes sense for you)

[woven dome]

found the issue, but dunno what causes it
some animation was overriding the paramter with a curve due to the name matching
renaming my parameter fixed it

private void FixedUpdate()
{
        _rigidbody.AddForce(-_rigidbody.velocity.y /        Time.fixedDeltaTime *     Vector3.up, ForceMode.Acceleration);
}

I just want to stop the cube from falling by applying the foce in the same direction reversed. But it still falls very slowly, how do I solve this?

[lean sail]

you can just turn off gravity on the rb component

[golden kindle]

I simplified it as much as possible, in the real situation I can only apply forces and not manually change the gravity or velocity

[lean sail]

why? this is just gonna be backwards. you shouldnt apply gravity, then counteract it, if you dont want it in the first place

[lean sail]

also i dont think that alone would work, you'd need to consider the accumulated force as well. if you add force in the same fixed update, the velocity doesnt actually update til the next physics step.
that equation looks a bit off too. you shouldnt need to add DT in the eqation. the forcemode equation you choose can apply it already

[golden kindle]

I may be simulating grip anong a specific axis. In that scenario I want to apply a exact and equal force in the opposite direction. That's what I''m doing in the example but the cube still very slightly moves down

[golden kindle]

I'm converting the velocity to an equal acceleration in the oppisite direction. acceleration is velocity over time. At least that's what I think it correct now

[golden kindle]

I think it has to do with the fact that the force is only applyed in the next physics step. That's what it seems like when it slowly moves down

Here is when I activate the force when at y < 2

so I need to change the rigidbody acceleration during the same step I guess

or undo the last step

[dim umbra]

just wanted to make sure I'm not messing something up, this is the correct way to have the game run at 60 physics updates per second, right?

if there's a more precise way to have exactly 60 that would be preferable, since timer systems will be important to the game

[leaden ice]

Yes

The most precise would be to do this in code:

Time.fixedDeltaTime = 1f/60f;```

[zinc parrot]

Hey in webgpu, what rendertexture formats can be written to in a compute shader? I find that neither rgbafloat or rgbahalf can be written to

[spare dome]

you would want to set the velocity directly to have more precise control

[leaden ice]

You mean WebGL I assume? It depends on the hardware. You can use https://docs.unity3d.com/ScriptReference/SystemInfo.SupportsTextureFormat.html to find out

[zinc parrot]

no, webgpu

but its not really about whether or not it supports it, I need to know if its read/writeable for a rendertexture

[spare dome]

is that a unity question then?

why dont you look your question up?

[zinc parrot]

yes being built for webgpu with unity
and I have but theres not many resources on specifically webgpu for unity

and the webgpu without unity hasnt helped much either

[rigid island]

I think you need unity 6 for webgpu

[leaden ice]

I see - webgpu support in Unity is in early access

that would be why resources are limited

[zinc parrot]

Yeah

[cosmic rain]

1. Did you confirm that it works in the editor or a non we GPU build?
2. Did you check the console for errors?

[zinc parrot]

The only resource I could find really said that it only supported single component for rw
But that it would be fixed in 6000.0.2f1…

Can you even run webgpu in the editor?

[cosmic rain]

No. Which is why I'm asking.

To make sure it's not an issue with your setup

[zinc parrot]

The only way I could really debug was to inspect the web console in builds

[cosmic rain]

Test it with different graphics API.

[zinc parrot]

And it kept saying that argbfloat32 can’t be read/write

Vulcan, dx12, and dx11 work fine

[cosmic rain]

What was the exact error?

[zinc parrot]

I will have to get the exact error later here, walking home from class

[cosmic rain]

I see. I imagine the final goal is for the webgpu to work the same way as the other graphics APIs. However, it's still not fully released, so I wouldn't be surprised that it doesn't work as intended yet.

[zinc parrot]

Yeee
I wouldn’t be surprised either
But the whole not being able to read write to basically any render texture… how did they manage to get deferred working lol

[cosmic rain]

I don't think you need to write to a render texture from a compute shader for deferred rendering to work.

Did you try running the samples that unity provides? Do they work correctly?

[zinc parrot]

So I know it works
If I disable my program completely(it’s a custom pathtracing renderer), it works fine

[obsidian anchor]

Heyah! I'm new here and am currently taking an beginner-level university course on learning Unity and C#, I am having a bit of an issue with case sensitivity for a particular prompt for ZigZagMovement script:

What it keeps getting wonky about is the placement of the zigzagMovement as a class reference instead of a function. What do I do?

[cosmic rain]

Wdym? Is there actually an error? What type is zigzagMovement?

[obsidian anchor]

Nm, I got it! zigZagmovement wasn't initially referenced in the X-axis script. It didn't have any function to reference.

[cosmic rain]

That sentence doesn't make any sense, but if you got it solved, then 👍

[leaden ice]

There is nothing resembling a function in this line of code.

[obsidian anchor]

Sorry, didn't share the entire thing. Should've done that.

[cosmic rain]

In various ways, but generally, the loading is done async, such that the game can update and render at it's normal frame rate.

What part of it? I didn't use any complex words.

Async means asynchronously and there are various ways to go about. The premise is that it executes in parallel with other code.

It doesn't necessarily have to be async await.

What I said has nothing to do with wether the game is multilayer or not.

As I said, they would usually generate the terrain asynchronously, such that the game can update normally while also generating the terrain.

It works for everyone. There's no reason for it not to work if implemented correctly.

I don't understand why you think multiplayer has anything to do with loading/generating the terrain asynchronously.

Has absolutely 0 relation.

Also, I'm not sure why you're talking about "ahead of time". This also has nothing to do with async.

You simply need to generate the terrain while allowing the app to update such that it can update and render the loading screen.

I can't give you exact steps, since it would depend heavily on your generation implementation.

I don't see how that contradicts what I said.

It fits in your step 4 and 5. Both of these steps would need to execute parallely.

Everything else is unrelated.

Ok, then what's the actual question? I thought you have a loading bar or something that is stuck when the terrain is generated?

I explained how.

But since you don't have a loading it doesn't really matter in your case.

You can just load it as you do it now.

There's no such thing as "let your computer use max CPU". The app doesn't have control over it. It always uses 100% of the CPU that the os gives it if it can.

No. There's no such threshold. The processor simply processes things at its pace.

You can't tell it to go faster or slower.

Unless you tune the hardware, which is unrelated here.

What kind of wait statements?
Even if you yield execution to the next frame, that doesn't change how fast CPU is processing things. It simple tells it "pause this work for now". The CPU would then try to do other work if it has any.

I don't think it should crash the server.

And if it does, then what is the cause? Did you actually debug it? Is it because the app is not responding to the os?

Well, you need to figure that out, because depending on the cause, there might be many different solutions.

Ok, then what is it?

What threshold is it? What kind of resources are you overusing?

What's max+?

But you have to. It is your responsibility as the developer and it's also the only way to address the issue.

I would understand why it happens first and then act accordingly.

A wild guess would be that you're running out of RAM or GPU memory.

So it has nothing to do with CPU.

Well, then what's right then?

The only other thing I can think about is that your server doesn't respond to the os, which I mentioned earlier.

How do you know that?

Investigate what allocates memory exceedingly and optimize that part using various techniques.

It depends on the cause. For example pooling. Or queuing the tasks so that they don't allocate the memory all at once. It depends.

Probably irrelevant, since it's on the server side. I forgot about it when I mentioned it earlier. But the answer is the same as with memory.

@spare dome setting velocity will allow for less control because I can't for instance break the rigidbody at a specific point only the whole body.

@lean sail The reason was because the gravity was applying in the following tick. So the velocity negating calculation was correct. The thing you see is the gravity applying one tick of force every frame.

The solution is to manually do the gravity force so you can add it to the negating calculation in the same frame.

    private void FixedUpdate()
    {
        Vector3 forcesNextTick = Vector3.zero;
        
        // Manually add gravity
        Vector3 gravity = Vector3.down * 9.8f;
        _rigidbody.AddForce(gravity, ForceMode.Acceleration);
        
        // Convert current velocity Y to acceleration
        forcesNextTick += _rigidbody.velocity.y / Time.fixedDeltaTime * Vector3.up;
        
        // We need to add the gravity force this tick
        // This is because the velocity above does not know about the newly added gravity force
        if(_includeNextTickForces)
            forcesNextTick += gravity;
        
        _rigidbody.AddForce(-forcesNextTick,ForceMode.Acceleration);
    }

[golden kindle]

Here it's simplified

    private void FixedUpdate()
    {
        // Add gravity
        _rigidbody.AddForce(Vector3.down * 9.8f, ForceMode.Acceleration);
        
        // Get current acceleration
        Vector3 currentAcceleration = _rigidbody.velocity.y / Time.fixedDeltaTime * Vector3.up;
        
        // Cancel out all forces
        _rigidbody.AddForce(-(_rigidbody.GetAccumulatedForce() + currentAcceleration), ForceMode.Acceleration);
    }

Now the only problem I have is that it does not take in to account forces from other bodies :/

and it seems to be unsolved https://discussions.unity.com/t/how-to-find-the-force-being-applied-to-a-rigidbody/831268/12

[fading tartan]

is it possible to display this number as a binary representation?

when looking the object

[golden kindle]

algorithm is a very very brought word

what kind are you making?

[golden kindle]

you could just convert decimal to binary

[knotty sun]

long val = 753458;
string bin = Convert.ToString(val, 2);

[unkempt steppe]

Do you think this is doable @golden kindle

[golden kindle]

Ye I think so, but this depends on how advanced you make it and how advanced you are

[tired elk]

Hi ! Is there a way to save changes made in Prefab Isolation Mode through script ? I found how to detect if I am in such a context, but the only method available on the PrefabStage that would make sense is ClearDirtiness(). Do I need to call AssetDatabase.SaveAssets() and then call ClearDirtiness ? SaveAssets on its own does not seem to do anything as the prefab is still marked as dirty with an asterisk (*) but it may not mean the changes are not saved ¯_(ツ)_/¯

[plucky inlet]

Do you want to change things on prefabs through script too, or just autosave when you change something in editor prefab mode?

[tired elk]

I make change through script that I want to save. Otherwise I would use the auto-save option.

[plucky inlet]

Did you checkout the utility? https://docs.unity3d.com/ScriptReference/PrefabUtility.html

[tired elk]

I did but was not sure it would make sense in Prefab Isolation. I saw ApplyPropertyOverride but assumed it would be for changes made on a prefab instance to be applied to the prefab.

[plucky inlet]

Maybe you could show your code how you "open" your prefab through script and make the changes.

[tired elk]

Actually it's not that I open a prefab. More context needed : I have attributes I can put on fields, properties or method to control the way they look in the inspector and extend the serialization to some stuff Unity normally does not handle. At some point, I had an issue that I fixed by dirtying the SerializedObject to force the refresh of the inspector. Outside Prefab Isolation, it's "fine" (not the best solution, but for now it works), but when I enter Prefab Isolation, the prefab is marked as dirty (obviously). Auto save would work, but my colleague wants to have it disable and ask if I can make the default dirtyness disappear.
So I'm checking if I am in a Prefab Isolation context to apply changes but do not know what to use to achieve my objective.

for (int index = 0; index < this.inspectorObject.TargetObjects.Length; index++)
{
    if (this.inspectorObject.TargetObjects[index] is UnityEngine.Object unityObject)
    {
        UnityEditor.EditorUtility.SetDirty(unityObject);
    }
}

UnityEditor.SceneManagement.PrefabStage prefabStage = UnityEditor.SceneManagement.PrefabStageUtility.GetCurrentPrefabStage();
if (prefabStage != null)
{
    // code underneath is probably wrong
    UnityEditor.AssetDatabase.SaveAssets();
    prefabStage.ClearDirtiness();
}

[plucky inlet]

Does not sound like the best approach, as you are targeting to different ways of modifying them. Maybe you guys should decide, if you want to use isolation mode or not? If not, you can just override as you do. But it also sounds quite counterintuitive to change prefabs that much without creating a variant anyways. Just trying to understand, why you would do so through script

Does autosave actually work ir hitting apply or is it still marked * when doing so with your custom serialisation?

[tired elk]

Autosave works.

And I agree it's more complicated than it should. The first purpose is to update data that are not manageable with SerializedObject in the first place. The code I shared above is just to "re-sync" everything at some key point (for example: code executed to fecth data by the object that should be replicated in the inspector).

[plucky inlet]

Are you sure you are getting this data and everything in correct order? Just wondering, if you are trying to save the prefab while its probably still fetching data, deserializing itself and therefore triggering new changes after you applied your cleardirtiness etc

[tired elk]

This code is called once the data is fetched, bound to the elements and displayed

But heh, there is still room for improvement

[plucky inlet]

Just for testing, did you just change a string or something simple and tried that again?

Change string, save the prefab and clear dirtiness, just to get all that custom jazz around out of testing and see, if you can save the preafb with simple changes

What I also found was something using

PrefabUtility.SaveAsPrefabAsset(yourInstance, yourPrefabPath);

as you got the prefabstage there, you could just get the instance from it and save it back to the path of your raw prefab

What I am also wondering. Are your changes saved even if its still marked * ?

[tired elk]

As mentioned earlier, I mark the object as dirty to force a refresh of the inspector. there's not necessarily changes to observe. so just by opening a prefab in isolation make the * appears (since the forced refresh happens once). SaveAssets on its own seems not to affect the dirtyness, hence my question if it is the right method.

[prisma hatch]

I.. I encountered this problem and its not even from any of my scripts?

can someone help me ith this, it happened twice, none of my script interact with this overlay script whatsoever, only a few has enabling or disabling agents, or ResetPath

[cosmic rain]

Probably a UI bug. Does it actually break anything in your project?

[prisma hatch]

no, it just stops the game and gives out the error

[prisma hatch]

so deos this mean i can just ignore it? as in when the game is built, it will not crash it whatsoever whenever an agent is active?

[cosmic rain]

Yes, it's an editor only error. it's not gonna happen in a build.

[prisma hatch]

thank you

[muted schooner]

PostLateUpdate.PlayerUpdateCanvases take up to 15% CPU usage. Is there a way to reduce it? As I understand from the profiler data, my healthbars are problematic. Each healthbar has it's own canvas, and it seems like it is a bad idea. I have to make healthbar the child of the object so I don't have to fetch it's position frequently, which will result with performance problems as well. So what's the optimal solution?

Alright, my solution was making ALL the objects that aregoing to have health bars on them a child of the same single world canvas.

In this way, I didn't need to fetch the locations manually and I had them being rendered properly with minimal performance loss

You guys are great, thank you so much. With the recent recommendations you made on my other questions, I increased optimal enemy amount from 400 to 1500.

sorry for the visual mess, lol. Just stress testing

[blissful mesa]

I'm trying to figure out a decent way to add scripts to my tiles for a mining game. I've painted a tilemap using rule tiles. Now I want to be able to click on a tile to remove it.

This would require me to attach a script to the tile but my brain is breaking. Can anyone point me in the right direction?

[muted schooner]

about script attaching - you can use scriptable objects.
https://youtu.be/XIqtZnqutGg

This tutorial does not directly link a tile instance to a script, I think it's not possible at all, but instead he attaches the tile type to a scriptable object with some data. When X tile gets clicked, he looks for a scriptable object that has the X tile in attached tiles list, then uses the found element to have the data.

if you want to attach a script to a specific tile and not tile type, then that's honestly out of my limits

for an instance, the tutorial guy in the video uses two tile types, "Grass" and "Stone". He doesn't attach scripts to tiles manually, but instead uses the tile types

the same guy has a tutorial that fits your needs better https://youtu.be/hPsB6MiJPQY

continuation of the first tutorial

[blissful mesa]

Thank you for sharing these. I was looking into that first video before but in my mind I'm thinking a solution where the logic is attached to the tile itself works better.

Maybe that just isn't the best way after all though.

I see rule tiles have a default game object option but wasn't quite sure how to make use of this

[balmy nacelle]

i've been working on a "light gun" game. Aim around the screen and shoot (doesn't rotate character like a normal fps)

I created a way for the gun to follow the mouse.

I am using the PSX shader from the asset store, since the screen is just a raw image / "render texture" the actual "raycast" is completely off and not "straight"

I assume it has something to do with the res, but at the same time there could also be an issue with my tracking / gun pos.

I've added offsets, no matter what. when i put the mouse far left or far right of the screen, its out of wack.

private void PointWeaponAtMouse()
{
    // Get the adjusted mouse position based on the provided offsets
    Vector3 adjustedMousePosition = new Vector3(Input.mousePosition.x + xOffset, Input.mousePosition.y + yOffset, Input.mousePosition.z);

    // Raycast from the camera through the adjusted mouse position to get the world point
    Ray ray = playerCamera.ScreenPointToRay(adjustedMousePosition);
    RaycastHit hit;
    Vector3 targetPosition;

    if (Physics.Raycast(ray, out hit, gunRange))
    {
        // If the ray hits an object, aim at the hit point
        targetPosition = hit.point;
    }
    else
    {
        // If no object is hit, aim at the farthest point along the ray
        targetPosition = ray.origin + (ray.direction * gunRange);
    }

    // Calculate direction from the weapon tip to the target point
    Vector3 direction = targetPosition - weaponTip.position;

    // Rotate the weapon body to look at the target point
    weaponBody.rotation = Quaternion.LookRotation(direction);
}

[hard tapir]

This must be joke, does unity remote config supports arrays?

When I tried to get that JSON with array through cloud code then it worked in dashboard, but it doesnt work in unity itself

this is very confusing

[thick terrace]

what do you mean it didn't work?

[hard tapir]

I fixed it, it wrong version of that Json was saved in cloud save

[modern creek]

I have some TMPro font .asset files which keep being updated/modified by unity and are making my git workflow a bit of a pain in the ass. The files have no modified data. Any tips/workarounds?

[gray mural]

You have to add git ignore for TMP

[modern creek]

Hm, I have a gitignore file in another project with TMP that doesn't have this issue.. what would be different about this project? Also, I'm not exactly sure what to filter here - i'm assuming .asset files are needed elsewhere in the project

[native copper]

I have a question. So I'm using this code to make my simple enemy ai walk around at random points within a circle;

    {
        Vector3 randomPoint = center + Random.insideUnitSphere * range;
        NavMeshHit hit;

        if (NavMesh.SamplePosition(randomPoint, out hit, distance, NavMesh.AllAreas))
        {
            result = hit.position;
            return true;
        }

        result = Vector3.zero;
        return false;
    }

    void Patrol()
    {
        if (agent.remainingDistance <= agent.stoppingDistance)
        {
            Vector3 point;

            if (RandomPoint(transform.position, moveRange, out point))
            {
                transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(point), turnSpeed * Time.deltaTime);

                Debug.DrawRay(point, Vector3.up, Color.blue, 1.0f);
                agent.SetDestination(point);
            }
        }
    }```

But I don't want it to move at random points within a circle, cause oftentimes it'll just keep going back and forth. Does anyone have any tips for how I could make the movement feel much more natural, like having the random point be within it's cone of vison rather than a circle around it?

[gray mural]

If you say your another project doesn't have this same issue, can this issue be resolved by reloading the troublesome project's environment?

[modern creek]

What, like a full library rebuild..?

I mean, I can do that but I'm just not sure why that would prove it - I'm not doing any sort of full rebuild in project B - every time I do something in the scene in B, the .asset files get touched by unity

my gitignore from project A doesn't contain anything specific to TMPro

https://pastebin.com/Dm1cErgn that's my template currently

[gray mural]

Hold on, does your another project have the same issue?

[modern creek]

project A & B both use that gitignore, have TMPro, but project B updates the .asset files for some reason

project B is unity6, project A is 2022.3

[gray mural]

Project A doesn't, even though the modifications are the same?

[modern creek]

I mean, I'm not modifying the fonts in either project so.. yes?

I don't know if I understand the question

I'll try to find a minimal reproduceable use case.. I think it's literally as simple as "drag a prefab into a scene that contains a GO with a TMPro component"

[gray mural]

Do you have to save the scene for this issue to appear?

[modern creek]

I think so, yeah.. but I have my unity setup to save the scene on play so I'm sorta saving it (implicitly) all the time

Yeah so.. lemme snap a vid. Fresh commit - just add a prefab to a scene (prefab contains a TMPro component and almost nothing else), save the scene.. asset files are mucked with

[gray mural]

I would still try adding a git ignore for tmp if it's not added yet

It's

[Tt]extMesh [Pp]ro/

[modern creek]

i mean, what's the string I'm searching for? I imagine I can't gitignore .asset files (unity internal files, probably?) - and there's nothing in the path of those modified files that contains anything related to tmpro

[gray mural]

After user settings

[modern creek]

I'd have to move that shit into a textmeshpro folder.. and to some extent, those files belong in git since the project wouldn't build without them

i'd rather find out what the root cause is and why this happens in one project but not another..

(I haven't found anything in TMPro preferences)

[gray mural]

Yes, supposedly, the git ignore for tmp is triggered only when the tmp file in assets is changed

What I think is that you might have troubles with your .meta files

I would at least try Refreshing the asset database, reloading unity rebuilding the assembly

[modern creek]

I think it's this: https://discussions.unity.com/t/textmeshpro-font-asset-keeps-changing-in-source-control-despite-not-editing-it/754628/6

dynamic/static font assets

Yeah, that was it. Setting the imported fonts to static for all my fonts worked.

[olive bobcat]

Need help with terrain and noise.
For some reason when I generate the noise I get this result. the texture is rendered for a grid of 2x2 of 513x513 pixel. but it sux 🙄

I mean, the problem is about the squares

Sorry /AFK

[plush ridge]

So, is it best practice to just never get null reference errors? Or where is the balance the two? I heard something in a video earlier along the lines of "in case the sound manager isn't working for some reason you wont get a null reference" to me, it seems like a sound manager should always be working no matter what

[plush ridge]

I'm here cuz I'm a beginner but,
adding a bit of noise to an image with a gradient or blur often helps to diminish the noticeability of image artifacts like that and banding.

[lean sail]

You should basically never have a null reference error. Theres no best practice for doing something wrong

Oops fixed the wording

[plush ridge]

So I should in theory be able to write a whole script, with all references being null, and the script should be able to run (or just return) without throwing any errors?
Doesn't that cause a headache with debugging while developing because you won't know if something is missing?

[lean sail]

No, this doesnt really make sense. Let's take a simple example, a movement script but the object to move was null. How would you expect the script to run? What would you expect it to move?
This shouldnt ever make it into the build. You see the error happen in the editor, you assign the reference and move on.

[urban lintel]

Can someone tell me whether this is a fine practice or whether there's a better way of achieving this effect?

I want to have grid movement (so ideally it's discrete) but want the sprite itself to smoothly follow the movement through dotween. I've separated the gameobject of the entity from the gameobject containing the sprite, and made this second object lerp to the original object in the update loop. This works fine, but I'm reading that in order to use something like dotween, you don't wanna call the dotween in the update loop (and I do get a warning for it in runtime when i do). So my guess was going to be to add an event to the original object along the lines of OnPositionChanged and then subscribe to that from the visual object and call the dotween there.

Is this a fine approach? I could also have the visual object be referenced in the main object script but I figured that if I ever want multiple things to react to the change, this would be a better way of doing it.

[plush ridge]

Alright fair enough. Thank you for the info! I guess I shouldn't be getting a bunch of null references when I stop play mode. Will fix those now. Thanks!

[outer plinth]

Hey, can anyone give me an idea of why my rotations might feel so unnatural? I've tried to use a Quadratic Ease in function to make the blend smoother but it still feels and looks horrible

https://pastebin.com/SZTk4Sv1

[lean sail]

I find it kinda confusing what you're actually doing here. Dotween should be used more like coroutines, and not something you start logic for every frame.
I dont really know what this second object or separation of objects is for

[urban lintel]

I want the movement of the actual item to be instant and discrete, so only 1.0, 2.0 etc., but want the sprite to tween between the two positions for the course of 1 second for example. I wasn't sure how to separate those two movements so I put the sprite in another object and just made it follow the original object

[lean sail]

Then yea you could use an event and just start the tween from there. Though I'd just use update tbh

[urban lintel]

Update with lerp?

[lean sail]

Lerp if you want it to move a percent over time, MoveTowards if you want it to move a certain amount per second

[modern creek]

Just to add to what bawsi said, what a "null reference exception" actually is is worth knowing. Little bit of programming history - you used to have to manually declare a block of memory to hold something like a game object, and you'd "reference" to it using a variable that held a pointer to that memory. That block of memory would have variables and so on. Say the size of your object is 100 bytes and the speed variable is located 16 bytes from the start of the block.. the executable would know that speed is defined at the address of the "pointer" plus 16 bytes.. or that it would need to write the new value to that location.

In other languages, if you didn't set your pointer properly, you'd try to set variables in memory where they shouldn't be - leading to your computer crashing usually.

Modern languages (mostly) have this "null reference" checking. So.. yeah, you're not supposed to do it. 🙂 Check to see if the value is null and if so, do the appropriate thing

[urban lintel]

As in use lerp on the sprite object to just transition over time? I was just gonna use dotween to learn it and since it seemed easier to specify my movement in seconds and such tbh

Also seemed to have decent APIs for things like animation curves

[olive bobcat]

Indeed but I don't get why, if the resolution is correct:

    {
        NativeArray<float> noiseResult = new NativeArray<float>(resolution * resolution, Allocator.TempJob);

        for (int y = 0; y < resolution; y++)
        {
            for (int x = 0; x < resolution; x++)
            {
                float sampleX = (x + seed) / (float)resolution * scale;
                float sampleY = (y + seed) / (float)resolution * scale;
                float noiseValue = Mathf.PerlinNoise(sampleX, sampleY);
                noiseResult[y * resolution + x] = noiseValue;
            }
        }

        return noiseResult;
    }```

but the noise at the end sux, in quality and when I render it, looks like the pictures above 😦

[lean sail]

Yes lerp would be used to move it overtime. Im not a big fan of dotween because of the memory allocations and I've really never felt like I've needed it

[spare dome]

break the rigidbody at a specific point? was this about rigidbody joints? if not then explain

using the velocity would give you more control due to the fact that you can set it to whatever you would need

[plush ridge]

Thanks for that. It makes sense. I guess I just need to assume everything, even like a game manager could be null? Seems like a ton of extra code to add all the null checks but I most likely just need to learn how to do it properly

[modern creek]

you probably want to learn the singleton pattern for your game manager so you aren't having to write a lot of boilerplate code through your app

Not everyone likes this pattern but I do 🙂 Lemme paste you some code

[plush ridge]

I have it set up as singleton, I was just using it as an example but yeah, thank you!

I'm inheriting from a Singleton class B)

[modern creek]

If it's a singleton then you don't need to check if it's null

I wouldn't use that .. I'd probably use it as a DDOL and manually managed singleton

[lean sail]

Theres no need to null check everything. As I said before, let the error happen in editor then assign the reference and move on.

[modern creek]

    public class GameManager : MonoBehaviour
    {
        private static GameManager instance;
        private static GameManager Instance => instance == null ? FindFirstObjectByType<GameManager>() : instance;
        private void Awake()
        {
            if (instance != null)
            {
                Destroy(gameObject);
                return;
            }
            instance = this;
        }
    }

something like that

(in a DDOL in your loading scene)

[plush ridge]

Only if it persists/is don't do destroy on load, right? My singleton is not persistent, as it will only be used in a specific lobby (at least this was my theory when I made it, haven't gotten far enough to find out)

[modern creek]

then your methods are like:

        public static void StartNewGame() => Instance.StartNewGameInternal();
        private void StartNewGameInternal() { ... do the stuff ...}

yeah, then you can manually load/destroy it for that scene

I just like the singleton approach because it makes interacting with the domain layer (the logic guts) pretty easy from anywhere

and then I pub/sub messages out to the UI to react to

but again, this isn't everyone's favorite approach and there's a lotta ways to skin this cat

[plush ridge]

Ohhh okay we're on the same page now. I don't actively have null errors. I fix them. I was just wondering if I needed to fix them and set up an extra layer of "security" with a null check

[modern creek]

always, yes

[lean sail]

Sometimes I do setup that extra null check if it's not something easy to debug. But stuff like accessing a singleton and somehow its null is usually the same execution order error.
If it's something thatd make me wonder how its null, I'll check and throw my own error with a more descriptive message

Well not throw, but LogError which I guess might throw by itself?

[plush ridge]

That's pretty much what I'm doing, very careful with where I use references to the game manager but there are a few "entity level" places where I reference it.

[plush ridge]

You just spotted a problem I didn't realize I had. I was thinking null checks were annoying because they hide the null reference - but that's because I'm not catching the exception I'm just using an if statement to return from functions or just skip stuff altogether. Thanks!

^ is the solution for this try-catch statements? or what's my next google search? if ya don't mind me asking

[lean sail]

You shouldnt really need try catch here, depends what you're doing. Imo try catch is more for errors out of your control.
Like trying to read a file but the user deleted it. Not like "I forgot to assign this in inspector"

The solution really is just assigning the reference and running the game again. Theres nothing you should do code wise if you just didnt assign it

[plush ridge]

10-4. thanks!

[silk narwhal]

Would also like to add a general solution for easier singleton adding. This does confine you to this base class, but you usually do managers etc. as a direct child of MonoBehaviour so this works pretty much every time for me

using UnityEngine;

public class Singleton<T> : MonoBehaviour where T : Component
{
    public static T Instance;
    public bool m_DontDestroyOnLoad = false;

    protected virtual void Awake()
    {
        if (Instance == null)
        {
            Instance = this as T;
            if(m_DontDestroyOnLoad)
                DontDestroyOnLoad(this);
        }
    }

    protected bool isTheOne()=>Instance == this;
}

you then do a

public class ShopController : Singleton<ShopController>

for example

you can add things like dontdestroyonload like i did, or handling more than 1 instance being detected (e.g. when scene-switching)

[runic pawn]

i have a function from an API that takes as an argument an Action<T, Channel>:

        public void RegisterBroadcast<T>(Action<T, Channel> handler) where T : struct, IBroadcast

my question is can i pass an async UniTask into this instead somehow, like this:

        private async UniTask OnMessageRecieved(RoomBroadcast msg, FishNet.Transporting.Channel channel)

currently it only works if its async void

[simple egret]

Action requires the receiver method to return void, so your method is not compatible.
You could use an async lambda expression (or another async method) that returns void to wrap your incompatible method

RegisterBroadcast(async (msg, channel) => await OnMessageReceived(message, channel))

// or

RegisterBroadcast(Handler);
// + 
private async void Handler(RoomBroadcast msg, Channel channel) => await OnMessageReceived(message, channel);

[runic pawn]

well i am trying to use UniTask since that seems to be what works for my webgl app, i'm not sure if another async lambda will work

hmmm ok

[simple egret]

The two signatures are incompatible so you cannot do that without a "conversion" first

[dim umbra]

Currently have some code in fixed update that I want to still be able to run when timescale is 0. I tried to do something like this to replicate it since I heard that coroutines still worked at 0 timescale, but I'm not super familiar with them and it doesn't work. Is what I'm trying to do possible?

by doesnt work I mean it just prints once

[simple egret]

How are you starting the coroutine?

[dim umbra]

On awake

[rigid island]

use wait for seconds realtime btw if timescale is 0

[simple egret]

Post the code, I suspect the issue is there

[dim umbra]

gotcha

oops

If I want to move this mob all around the room (e.g. walking on the walls) and like faster and faster, does it make more sense to do it in Animation > Animation (and create an attack1 animation let's say); or should I proceed programmatically?
If programmatically, how do you handle the 6 body parts ? (since the mob would have to "break" in some sense as some parts would be on the vertical wall while others still on the floor)

It's a boss battle room like in Kirby so cam is locked when player is in combat zone

[golden kindle]

even setting the velocity directly does not solve the problem. During the same tick there will still be a force applied from ether gravity or other forces during the tick

[stark fiber]

hey guys, any idea what might cause the line Camera.main.ScreenToWorldPoint(Mouse.current.position.ReadValue()); to return a different thing when used in two different scripts, in the same frame? I don't touch anything that would mess with the camera or the mouse

[rigid island]

different in what way?

[stark fiber]

one time it's what you'd expect, the other it returns a vector3 with infinity in all positions

my only hint for what might be going wrong is that it's infinity when I query sceentoworldpoint in a script attached to the camera itself

[rigid island]

where are you checking that?

[stark fiber]

in update, in a script attached to the camera

[rigid island]

did you check which position value before it goes into the ScreenToWorld?

try assigning the Z value to it because if you're using prospective especially the Camera does affect it indeed

[stark fiber]

ah, I rubber ducky'ed my way to the solution, it was shooting errors so fast I didn't see, but I'm actually just stupid i incremented the value of the position of the camera instead of changing it, resulting in infinity after very little time

thanks!

[rigid island]

hah nice!

[mild dock]

Does anyone have any tutorial* recommendations for procedural world generation - biome generation? Something 2d but theres very few 2d tutorials in this topic and its just basic noise and not like a real biome generator. And 3d ones have conditions for like air or water, Whereas my terrain does not.

[dire lava]

Something like terraria ?

[mild dock]

Yeah that'd be a good example

kinda, it also has air/water/liquid calculations, mine doesnt

im trying to fill a map with biomes, But each attempt i keep just randomly getting random results. Like ocean is next to mountain next to plains next to ocean next to plains next to ocean, i think i messed it up bad and just deleted it xD

and now i need to refresh on something new here because im doing somethin wrong lol

[dire lava]

https://youtu.be/PaDUYXfbiL0?si=RSSa-MVvTcrnMvTa

Try this

İ just looked it up

Search "terraria biome generation" or "2d mc generation"

[simple void]

2D Game like Minecraft is a bit contradictory ngl

[mild dock]

Yeah unfortunately thats just an else if video on the topic unfortunately. Its just checking if this works and then else if to the next

[dire lava]

Oh let me search in Forma

[mild dock]

What im trying to do is populate like a voronoi diagram

Which i admittedly iv tried but thats what i threw out xD dont think i did it right or its just not possible to use for what im attempting

[paper pine]

Hey everyone, I'm working on a third-person controller in Unity and need some help with animation blending.

I've got the movement logic done, and my animations for walking forwards, backwards, left, and right are working perfectly. The problem comes in when I try to blend animations for diagonal movement (like walking left-forward or right-backward). I'm using a blend tree in Unity, and while the animation looks good, it plays very slowly during these diagonal movements. Another Problem which i encounter when trying to move diagonally in the backwards directions is that the left and right animations are swapped.

Has anyone else run into this issue or have any suggestions on how to fix it? Thanks in advance!

[dire lava]

Are you using tile maps ?

[simple void]

If your problem is oceans next to mountains or rapid changes in terrain, what you should do is instead of making the biome decide the terrain, make the terrain smooth and pick the biome based on the local terrain shape—if that makes sense.

[mild dock]

Tile maps? Like as in its a grid based system yes, chunk based, like unity terrains but has different triangle/vertice counts and saving etc.

[dire lava]

Yes grid system.s

[dire lava]

Did you try something like this ?

[mild dock]

Unfortunately that too also leads to else if statements. If you do lets say make a map and each noise value = a chunk, You get stuck with consistent islands and consistent mountains of the same shape etc. I need to achieve like, Some more randomness, And im struggling to get that part, Because both deserts and plains will share the same height values, Forests too.

Like if i said 0.4 to 0.49 is plains, 0.5 to 0.59 deserts, 0.3 to 0.39 is forests, It will consistently be those regardless where you walk, Which does solve the inconsistency with biome grouping placement but makes the world super repetitive and predictable

[dire lava]

Just zoom the peeling noise inside and out for different noises no ?

[mild dock]

Whats that

[simple void]

Then you add some random maps like temperature humidity or weirdness for variety

Also there’s a way to expedite the process don’t check every biome using a list of if-else statements, if that’s what you’re thinking.

For a one parameter, let’s say you define your biomes off the terrain height, you can use a binary tree or smthing to determine the Biome in O(log n) for higher dimensions(more conditions) you get a similar performance using R-Trees

[mild dock]

Okay thanks yall

Also Gweam you lead me down a new rabit hole, thank you

just found Ridge Noise along with this peeling noise topic

[simple void]

Peeling noise?

Do you mean perlin noise?

[mild dock]

Yeah, Its a topic i just found googling zooming in (scale) on noise, Something something sampling still reading

[simple void]

Ah ok, I recommend simplex noise, perlin noise is slower, more artifacts and outdated but everyone still uses it cause it’s more famous 🤷

[mild dock]

iv heard of it, not bothered with it, Wanna tell me about some advantages of it over perlin?

aside from performance

[simple void]

Less dimensional artifacts

It’s hard to explain atm

[mild dock]

fair xD

[dire lava]

Lol

[short hatch]

[weak dove]

Hi, I'm working on making a GOAP AI system for my game, but I'm a little stuck on how to handle types in C#.

For example, I have a class called EatAction<IEatable>. I have a bunch of food item classes that implement the interface IEatable (eg. Apple, Chicken etc..)

I want to be able to consider EatAction for each of these different food classes (EatAction<Apple>, EatAction<Chicken>) AND after that I also want to be able to set a specific instance of the food class as a target. So the IEatable part of EatAction<IEatable> can refer to the IEatable interface, classes of specific types that implement the interface, and also instances of these specific objects.

Tried to just make a list of EatActions with all the different food classes as a target, but I'm getting this error:

[olive bobcat]

Stupid question, why the type is lowercase? 😅

[weak dove]

Just temporary code to try and figure out how to handle this

I guess it should be eatableType?

[winter jacinth]

Is there any toggle to make it so the cursor doesnt move when im doing things in viewport like moving around and turning while holding RMB?

[weak dove]

Cursor.lockState = CursorLockMode.Locked; ?

And then Cursor.lockState = CursorLockMode.None; on RMB up

[lean sail]

Is there any reason you're using generics here, instead of just passing the item to eat in the constructor?

If the generic is constrained only to IEatable I dont think you need it to be generic

[weak dove]

Yeah I think I'm misusing generics here

I changed it to this:

So the variable target should be able to hold classes that implement IEatable, and also specific instances of those classes, I think?

[lean sail]

Not sure what you mean hold classes and instances of the class. It's just a variable, which so happens to be of type IEatable. It will hold any instance that implements IEatable

[short hatch]

that was attached I supposed ..

but it works

[weak dove]

I don't want it to just hold instances though. I want it to also hold classes that implement IEatable without assigning a specific instance of that class.

[lean sail]

That makes no sense

[weak dove]

For example, I have classes "Apple" and "Meat" that implement IEatable. In the GOAP planner I want to consider EatAction with each of these classes, without having to supply specific instances of those classes, because there might not even be any instances in scene. Later, it would check if any instances of those types exist, and if so, set the target to one of those instances.

Like when the agent is first considering eating an apple, they need to consider doing EatAction to the abstract concept of an apple (ie. the class Apple), not a specific instance of an apple.

[lean sail]

I'm not sure how your system is setup, but still this makes no sense. Are you familiar with c# fundamentals?
If you declare a variable of type IEatable, the only thing you're gonna store in there is an instance of something implementing IEatable. It sounds like you want to store the type of each thing implementing IEatable but this sounds wrong to need to do, unless it's purely for some editor functionality

Im also not sure what the goap planner is or looks like. wouldnt it make more sense to consider what foods are available first before looking at every eatable item, then decide what to eat? Rather than having it consider every type just for there not to be an instance

[weak dove]

Yeah, I want to store the type of each class implementing IEatable.

[weak dove]

Not for what I want to achieve. For example, there may be no instances of the class Meat in the world, but the agent knows that if they kill a chicken that will instantiate a Meat object. So they first need to consider eating Meat (as a class, not an instance), and then if the plan is selected the action will be applied to a specific instance of Meat.

One workaround I can think of is just to make an instance of each class (Apple, Meat) in the scene, but use them as a reference instead of a target. Then I could have two variables "targetType" and "targetInstance". targetType would hold the reference instance, and targetInstance would only get set when an actual instance of the class is found.

[lean sail]

Well im still not entirely sure what youd use it for but Type exists. Though it's usually not the cleanest, to need to account for every deriving type, when implementing an interface is used to avoid needing the actual type in the first place. https://learn.microsoft.com/en-us/dotnet/api/system.type?view=net-8.0

[weak dove]

That would still require two separate variables, right? One Type variable and one IEatable variable (to refer to the instance).

[weak dove]

Maybe this approach would be easier/cleaner?

[chilly surge]

What are you going to do with the type?

Are you going to create an instance of it, find components of it, or what?

[lean sail]

I'm still really unsure how you're going to be using it too, so I'm not sure. I was assuming youd have a list of types elsewhere

[weak dove]

I would be checking the predefined variables of the class and comparing it to the predefined variables of other classes. For example, every instance of Apple is instantiated with a nutritionValue of 50, but every instance of Meat has a nutritionValue of 200.

[chilly surge]

How do you check the predefined value if you don't have an instance of it to check?

[weak dove]

Now that I think about it, it's not possible to get values of Types, so having a placeholder instance of every item would probably make the most sense.

[chilly surge]

You would be able to do it with static abstract in newer C#, but unfortunately Unity is stuck on an old version of C#.

[thick terrace]

sounds like maybe it'd be possible to separate this so you don't have duplicates of eg the Meat data floating around? you could make Meat a scriptable object and have each instance in the world reference it

[weak dove]

Yeah, I think that would make sense too

Btw thanks for the advice everyone!

[unkempt steppe]

hey guys, does unity have coding?

[somber nacelle]

wdym by "have coding"

[knotty sun]

it would be very odd the have the channel you are posting in if it didn't

[unkempt steppe]

right lmao
cause i have research and i have to develop an algorithm to make a 3d avatar based on user input (ther physical attributes)

[knotty sun]

I remember from yesterday and I'm still not sure of the correlation between algorithm and code in your case. You do not need code to develop an algorithm

[unkempt steppe]

what do you need to make an algorithm?

[knotty sun]

pen and paper

[unkempt steppe]

i need help i'm losing hope for my research...

i don't wanna fuck this up

[unkempt steppe]

and what should i do next? can you guide me?

[knotty sun]

no, I am not your professor. Did you go and ask him about your research sources as discussed yesterday?

[unkempt steppe]

wdym yesterday?

[knotty sun]

you do not remember yesterday?

[unkempt steppe]

we have to get existing papers as our research sources

[cosmic rain]

What are you studying? Surely the research is related to your major..?

[unkempt steppe]

yes

[knotty sun]

then that is where you start

[cosmic rain]

So, you should know how to make algorithms..?

[unkempt steppe]

I already found algorithms from existing papers like parametric modeling, morphing algorithm and SMLP (i'm not actually sure if these are algorithms).

since there are like a 1000 different ways to do what we're describing, the algorithm will be my own, but i can stitch it together based on existing work and existing algorithms.

[unkempt steppe]

yes, it is part of my objective. i know how to code but literally have no experience when it comes to 3d animation. and i'm still learning

[cosmic rain]

Then learn it. Unity manual and documentation is in free acceess. And you have the whole internet of information as well.

[knotty sun]

coding is irrelevant, an algorithm is not code. Code is what you use to implement an algorithm but you have to design the algorithm first

[unkempt steppe]

yes after the algorithm, i have to code it

[unkempt steppe]

yes but i need guidance cause i'm kinda losing hope... do you have an idea on how to do it?

[cosmic rain]

I'm not even sure what you're trying to do. That's the part where you take pen and paper and write down the algorithm

This doesn't sound much like an algorithm to me. Just a simple app with ui and and some code.

[unkempt steppe]

but i think there has to be some way to make it unique right?

[cosmic rain]

Wdym by unique?

[unkempt steppe]

i just don't have to copy and paste the existing algorithms, i have to design my own by stitching together based on existing work and existing algorithms

[knotty sun]

I think you need to go and talk to your professor and ask him for guidance, especially in terms of deliverables because it strikes me you have no concrete idea of what you are even supposed to be doing

[unkempt steppe]

you're right lol, this is what my group members have planned

do you know parametric modeling, morphing and smlp btw?

[knotty sun]

yes, of course I do, but don't expect that level of help from me, I gave up teaching many years ago

[unkempt steppe]

alright, i just wanna ask if i can apply it while using a 3d engine?

[knotty sun]

Absolutely, 3D is irrelevant in the context

[unkempt steppe]

what do you mean?

[knotty sun]

that's the point. the algorithm is the same it's just the implementation of the algorithm that is different

[unkempt steppe]

i mean why is 3d irrelevant in the context? i believe these methods are for creating 3d models?

[knotty sun]

because the only difference is you are implementing a 3D vector rather than a 2D one, and that is an implementation detail, nothing whatsoever to do with the underlying algorithm

[unkempt steppe]

oh okay i think i misunderstood, implementation detail and an algorithm is different?

[knotty sun]

of course, as I said here #archived-code-general message

[unkempt steppe]

oh okay so you mean the implementation detail is a code?
uhm i would appreciate if you keep being patient with me...
i really wanna understand what i wanna do

[knotty sun]

yes, the code is the implementation. the algorithm is the theory

of course they must, so what you should be researching is the underlying concepts of those techniques, not the implementations of them

[unkempt steppe]

alright, i'll try to find articles or research papers. i hope i'm doing it right

[unkempt steppe]

uhm can i dm btw? if that's alright

[knotty sun]

no, absolutely not

[unkempt steppe]

okay sure

[unkempt steppe]

i just don't wanna spill out the full details of my research while a lot of people can watch our message lol

but it's okay

[dusk apex]

You'd create a thread to avoid spamming the channel

[unkempt steppe]

right, would try that

[earnest gazelle]

Should we save the asset (prefab, SO) after changing the value of a serialized field through OnValidate?

        private void OnValidate()
        {
            if (_localId != 0) return;
            var ids = GetComponentsInChildren<IDataPersistence>(includeInactive: true)
                .Where(p => p != null)
                .Select(p => p.LocalId)
                .ToHashSet();
            var id = 1;
            while (true)
            {
                if (!ids.Contains(id))
                {
                    _localId = id;
                    break;
                }

                id++;
            }
        }
    }

[balmy nacelle]

Anyone?

[blissful mesa]

I have a tilemap with blocks on it. I'm trying to instantiate a GameObject with an animator and sprite renderer at runtime when I click a block. It plays an animation over the block on click.

However, attaching the sprite renderer really messes with the gameobject position. Visually, the tile and mouse position are far apart, but position wise it is similar.

gahhh I figured it out. the sprite import setting here is what fixed it. Set the sprite import to local space (I'm guessing before it was using the canvas size i had set up in Aseprite?)

hello, i need some help with the trail renderer component, I want to add a trail effect to my character moving in a grid but trail bends/diagonally draws when my character moves too fast in an L shape. how do i ensure the trail follows the L instead of bending?

[opaque vortex]

Is there any way to test my coding knowledge like a general test for c#? I want to know how much I do know, and do not.

[quaint rock]

for what purpose, like most would just start working on a project they want to get done

that will clearly show where you need to brush up on skills or not

[opaque vortex]

I am working on my project, but I spoke recently with a full stack devoloper and he asked me how long I was coding for. I said for around six months, and I realized I had no way besides showing my code itself to show what level of knowledge I had in the subject.

[dawn nebula]

How do you convert a quaternion to a point on a unit sphere?

[mellow sigil]

quaternion * Vector3.forward

[steady otter]

hello, I am making a game about clicking on randomly generated targets and getting points however I have run into some issues with the code such as the target that I want to instantiate being null. These are my 2 pieces of code that I am using to generate random positions of the targets https://paste.ofcode.org/qvPFhawUk79GbRPjNz9MwC and the code I am using for the targets themselves https://paste.ofcode.org/37AvpHs47rB9HP4tmc5tgQU

[dawn nebula]

I have a quaternion rotation, and I want to split it up into a pitch/yaw. (Angular rotation along X and Y axis). Any tips?

[somber nacelle]

the target that I want to instantiate being null
then element 0 of your targetPrefab array has nothing in it

[mellow sigil]

That's literally what Euler angles are

[steady otter]

Right I am trying to figure out how to make the code choose a random integer but I cannot just paste in the code to make a random range which is why I am confused on how I would be able to impliment a solution

[somber nacelle]

but I cannot just paste in the code to make a random range
show what you tried? i cannot provide a fix for a problem you have not bothered showing or even describing until just now. but even still, if there is nothing actually in the array then you won't be able to get something from the array

[dawn nebula]

Ok I think I'm overcomplicating this.
I have 2 normal vectors. I need normal vector A, to become normal Vector B, just through changes in rotation along the X and Y axis.

[mellow sigil]

It's not possible for all vectors. For some (most?) cases you need to rotate along X, Y and Z, or rotate first X, then Y and again X (in local space)

in 3D space that is

[dawn nebula]

Ok so more context. I have this sphere. I want to be able to hover over a region of this sphere with a mouse, and zoom on that point specifically. This is what I have currently.

    void Update()
    {
        var delta = Input.GetAxis("Mouse ScrollWheel") * scrollSpeed;

        var newScale = Mathf.Clamp(currentScale + delta, 1, 100);

        var input = new Vector3(Input.mousePosition.x, Input.mousePosition.y, Camera.main.transform.position.z);
        Ray ray = Camera.main.ScreenPointToRay(input);

        if (Physics.Raycast(ray, out var hit))
        {
            normalIndicator.transform.position = hit.point;
            normalIndicator.transform.up = hit.normal;

            var angle = Vector3.Angle(Vector3.back, hit.normal);
            var arcLength = Mathf.PI * currentScale * (angle / 180);

            var scaleFactor = newScale / currentScale;

            var arcOffset = (arcLength * scaleFactor) - arcLength;

            float radians = arcOffset / newScale;
            float degreeOffset = radians * (180 / Mathf.PI);

            Vector3 axis = Vector3.Cross(hit.normal, Vector3.back);
            transform.rotation = Quaternion.AngleAxis(degreeOffset, axis) * sphere.rotation;          
        }

        sphere.localScale = Vector3.one * newScale;
        sphere.position = Vector3.forward * newScale;
        currentScale = newScale;
    }

This is the code that's doing it.

The issue is that the sphere is also rotating along the Z while it zooms in. I don't want this.

I have no idea how to resolve that.

[steady otter]

int randomNumber = Random.Range(0, 5); using this template to get a random range for my code

[somber nacelle]

you also need to say what errors you get

but also you should be using the length of the array, not an arbitrary number like 5 as the max

[steady otter]

Okay how would I set up the array though? I tried replacing targetPrefab for randomNumber and then dropping that into the code but that still just conflicts with the already existing code

[steady otter]

I would change the length to be 3 as that is how many random targets I have currently in the game

[somber nacelle]

can you be more specific than these vague phrases like "conflicts with the already existing code". you need to actually provide useful info that might help me figure out wtf you are doing wrong

[steady otter]

Okay the exact message is that the game manager already has targetPrefab defined sorry

[elfin tree]

I have a WebGL breaks that compresses/decompresses json with gzip, and for some reason, if I build it using "Runtime Speed w LTO" instead of "Shorter Build Time" I get an error at the moment a gzip function is called in the game, thoughts?

[steady otter]

I just can't wrap my head around what I would need to do to have random targets spawn in as everything is runs fine its just the extra targets

[somber nacelle]

that sounds like you've either declared the variable more than once or you created a copy of the script somehow

[steady otter]

okay I defined the targetpPrefab with the target class

[somber nacelle]

huh?

[steady otter]

private Target[] targetPrefab; is the exact line of code

[rigid island]

so you have twotargetPrefab according to your error

[steady otter]

yes and from here I do not know how to add on to the already existing definition of targetPrefab to make it an array

[rigid island]

its already an array with []

you create a new one with size and assign values if its not serialized

[steady otter]

okay gotcha

[rigid island]

you probably want to expose it in the inspector as [SerializeField]

[steady otter]

Yup got it

I set the array to be 3 in the inspector as I have 3 different targets that I want spawning and being treated the same as the targetPrefab

[kind carbon]

how can i send my code that isnt working

[steady otter]

There still is the error with the instantiate saying that it clones the object original and returns the flone

[somber nacelle]

provide the actual error message rather than a description of what you think it says

[rigid island]

yes putting an entire array in an UnityEngine.Object makes no sense
you're putting a box where its a hole for a sphere

[open plover]

            Touch touch = Input.GetTouch(0);
            if (EventSystem.current.IsPointerOverGameObject(touch.fingerId))
            {
                Debug.Log("yes");
                return;
            }
            if (um.gameState == GameState.MainMenu)
            {
                Debug.Log("touch");
                um.DraggedAtStart();
            }
``` This is in Update. "Yes" get logged like 5 times but after that it logs "touch". The touch is over an ui element. No idea why does it first correctly detect it is over an ui (multiple times) but then doesn't

[steady otter]

Okay what would be the correct code that should be placed instead?

[somber nacelle]

just so you are aware, the error message is that bottom line that starts with CS0311, that first line under the signature is the summary comment on the method that describes what the method does

[somber nacelle]

why not look at the code you shared before and compare what you had there (which was correct, but you just didn't have a random int chose)

[spare dome]

that looks exactly like google earth

i see no issues with it imo

[dawn nebula]

Controlling the rest of the Earth is kind of an absolute pain if it doesn't rotate around the poles.

[spare dome]

well lucky you that earth does

[dawn nebula]

not incorrect

[west bough]

My car is running away from another car. As it finds the shortest path in the navmesh while running away, it sticks to the side when it is going to turn the street. I want it to move exactly in the middle

how can I solve it ?

[steady moat]

I wouldnt use navmesh for such use case.

[rigid island]

Use splines

[west bough]

ok let me try that. thanks

[rigid island]

makes things easier

also we have the same city asset

[west bough]

ahahah, I think we are doing the same thing on this map

[west bough]

It looks very good.

[west bough]

The road splits in two. He'll have to go left or right at random. If I get in front of him, he'll have to run back. Can I do it all using splines? I tried coding it, but it seemed a bit like it was for npc animation.

[rigid island]

yes its a bit tricky though

it gets really annoying but its possible

basically you need to know the specific index you want to go too

[cold parrot]

if you don't want to code all your navigation yourself, you should look into A*PathfindingProject Pro which gives you a lot of tools for doing this kind of thing. Note however that no astar based pathfinding solution will be able to truly handle vehicles on its own since the algorithm cannot understand an actor that needs steering, so you need an implementation where you can configure the graph in a way that this doesn't matter for your particular usecase. Navmesh is inherently not well suited for vehicles. with APP you get a bunch of path post-processing and steering options what can make vehicles behave quite nicely.

[west bough]

$140 seemed a bit expensive for such a small project. I think I will keep trying splines

[cold parrot]

its not a project specific buy, you can keep using it for all other projects too 😉

in any case, point graphs (which is what you need here) are a feature of the fee version, pro is mostly for performance and advanced navmesh usage.

Question,I've made a Main Menu for my game,made it as a separate scene and when im pressing play it's supposed to send me to the main game scene with ((these dont really matter)a text and a blurry backround) after 3 seconds to unfreeze the scene and let me play,but instead it crashes and stops the run.I've tried testing in Build & Run but it just closed the game.If someone can help me and needs the script,tell me and I'll send it.

[west bough]

I have completed the code process, but there is a problem. It goes exactly as I drew it, but the car teleports there because the knot is at part 0,0,0

Is it possible to start the knot0 in the same position where I started drawing?

[normal sail]

script:

[rigid island]

which drawing?

[rigid island]

if you mean the one where the container lives on just copy and paste the position, they should be world post not local

Question, how can i code good graphics in unity 5 from scratch? I no longer want to copypaste someone else code, i want to do proper HLSL shennanigans With C# actually coded by me.

[rigid island]

I no longer pírate asset store packs

[floral timber]

Yessir

No more

[rigid island]

thats embarassing that people do that

[floral timber]

Why tho?

[rigid island]

because its usually a developer putting work and you're stealing

and its not some corpo, its an actual indie dev most of the time

not something to be said proudly 🤷‍♂️

[floral timber]

I Know, but doesnt éthics Apply on both sides?

I wouldnt sell or distribute the game With those assets Either, i Just was playing and testing them

Also im poor and underage so thats my point

[rigid island]

meh its still not something you want to mentioned at all esp in a room full of devs.

[floral timber]

Ooh

[rigid island]

piracy talk is against this server rules just for future reference #📖┃code-of-conduct

[floral timber]

Oh crud... i might been a little bit too honest

Yeah i realize

Well i already sent the message so hopefully nothing bad happens

[rigid island]

anyway if you want to learn C# you learn c# , unrelated to HLSL

HLSL is used to talk to graphics/shaders directly. C# is versatile in different things

[floral timber]

For a example, can i make a mirror in pure Csharp? Ive read that You have to code a shader

[rigid island]

It depends the end goal. Unity can do that without even needing code, but generally a shader is needed. In c# you would probably not do such a thing

ShaderGraph exists also and requires no code, or you can add custom functions

[floral timber]

Ohh let me search shadergraph to see if its What i think it is

[floral timber]

Its quite neat, but its avaliable on newer unity versions, im using 5.3.x ||(I AM NOT USING A CRACKED VERSION THOUGH, I use a old version for looking into exporting to 7/8th gen video game consoles)||

[cosmic rain]

Well, then you're limited by the technology of your time as they say.

[rigid island]

also how would you even aquire the modded version of unity for that console

[floral timber]

I want to do the graphics from scratch becuse of that

[rigid island]

iirc you signed NDA and that gave you special version of unity

or that was just nintendo / sony

[floral timber]

I Just downloaded the installer as a build module from archive.org and since the xbox 360 is out of support and we already had yknow... Microsoft XNA, i dont think theres anything wrong on using that

[cosmic rain]

Anyways, you'd either need to learn to write shaders(and pretty archaic ones too), or fake it via a scene setup/render textures(if that's even supported)

[floral timber]

Thats why i went here to seek help

Like documentation and resources

If theres even any

[cosmic rain]

The older manual and docs should be available in public access.

[steady otter]

Okay so I have added in a new array called randomIndex that has a random range of 0 - 2 as I have 3 different targets that I need to spawn in. that I then have then Instatiated with the same code that worked to spawn in 1 target before, I am still getting the object that I want to instate is full, this is my full code: https://paste.ofcode.org/37tQmQ3xn5vMdKep8B3LGmC

[somber nacelle]

i assume you mean "null" rather than "full" and you're still not providing the actual error message, so this is really only speculation but i'm going to, once again, assume that your array doesn't actually have anything in it.

also you're still using a magic number for the max parameter of Random.Range instead of the length of the array

[steady otter]

never mind I was just being stupid and forgot to put my prefabs into the actual unity inspector

thanks for putting up with my probably very frustrating explanations but I learned a lot

[hybrid portal]

does anyone know how to put mods into a minecraft server?

if so please dm me

[leaden ice]

You're lost.

[ancient sable]

Is there a way to efficiently determine, when a mesh collider collides with any non-mesh collider (such as a box collider), what ContactPoints collided within the bounds of what triangles (so I would have some sort of enumerable of all the triangles that had the ContactPoints, and it would incorporate all of the collision points (So maybe something like a dictionary where the key is the triangle, and the value is a list of ContactPoints))

[hybrid portal]

no i'm not, I figured i'd ask here .

[leaden ice]

You're lost. This is a Unity server

[hybrid portal]

yes. I. Know. I make games too. but I figured that someone could help.

[leaden ice]

Ask in a Minecraft server

Or Google it

[hybrid portal]

I'm not in one, Don't want any youtubers in my dm's

[hybrid portal]

I have. Multiple times. I don't want to pay $12 a month when I already have spent $28,000 on my servers.

[lean sail]

That doesnt change that this isnt the place to ask for that.

[hybrid portal]

does anyone know how to make a working save file that can branch upon 27 different scenes in a unity fine that also is programed to make a file on the users computer that holds the save data? also that can encrypt the data so that people cannot change the save data?

[cosmic rain]

Wdym by "branch upon 27 different scenes"? That sentence doesn't make any sense.

[hybrid portal]

[hybrid portal]

having, consisting of, or involving more than two branches

[cosmic rain]

What branches? What does it even mean in the context of save files?

[hybrid portal]

take a tree for example, a tree can have from 0-infinity amount of branches, in the end it is all connected to the stump. in this case, all of the saves can be connected throughout all of the scenes as well as the progress of which the player has made along the story of the game. The classrooms of my game are all put in different sections, kind of how "My Friendly Neighborhood" is set up.

in conclusion all of the progress would have to be saved throughout the whole game, location, enemies as well as the amount of coins the player has.

[cosmic rain]

If you just need to save different data per scene, then you can have a serializable struct/class with a key and value fields, where a key would be the name/id of the scene and the key is the data you want to save. Then just have an array of those and save them as json or binary. If you really need to do encryption, then you're gonna do it somewhere in between these steps and writing to a file.

[hybrid portal]

thank you for being a helpful individual on this server.

[cosmic rain]

You'd get a proper answer right away if you weren't spiting out off topic bullshit.

[ancient sable]

So is there an effective way that I hadn't thought of yet, or is iteration the only choice?

[jaunty sundial]

I dont get how im still getting floating point errors when im snapping the value to 2 decimal places

[vagrant blade]

You got your answer, be less annoying about it, thanks.

[leaden ice]

Show code and explain what errors you're getting?

[lean sail]

is Collision.GetContacts what you want? im not really sure what youre trying to do otherwise

[ancient sable]

No. Basically, one way to see it as I have a cube (not forced to be a cube, really any collider) and a mesh collider. In the OnCollisionEnter I want to determine what triangles in the mesh collider collided with with what contact points from the collision. So lets say there are 100 contact points spread over 3 triangles approx equally, one possible thing to have would be a Dictionary where the key is a triangle, and there are 3 keys with values, and all the values would be something like a List of ContactPoints that have about 33 elements

[jaunty sundial]

HPS = Snapping.Snap(HPS, 0.01f)```

[ancient sable]

so its similar, but I need them split up based on which specific triangle of the mesh collider they contacted with (so which 3 vertices are they contained within from my understanding of how it works. I haven't worked with meshes much)

And frankly, I dont even think I even actually need the contact points themselves. Just knowing what triangles is the most important part

[leaden ice]

And the error is?

[jaunty sundial]

That occasionally the value goes to something weird with like 9 decimal places

[leaden ice]

Well one issue here is that 0.01f is not even a number that can be represented cleanly in binary

[jaunty sundial]

So shod i do 1/100

[leaden ice]

So even trying to pass that value into the snap function is problematic

[jaunty sundial]

To be exact

[leaden ice]

No that's the same thing

There's no such thing as exact here

It's like trying to write 1/3 in decimal

You get 0.33333... repeating

In binary 1/100 and 1/10 are such numbers

What you should do is use integers to represent these values in the first place

[jaunty sundial]

How

[lean sail]

you could probably raycast against the collider using the collision contacts and get the triangle index https://docs.unity3d.com/ScriptReference/RaycastHit-triangleIndex.html
