Whats the suggested way to switch action maps from code?

[cold parrot]

ActionMap.enabled = true/false

Problem: I am making a match 4 game, but facing Index out of range exception when I try to swipe the tiles (visually they look like gear components in the game). Also sometimes if the gears get swiped, they are not at the correct position.

Reference Video: https://streamable.com/355ar3

Scripts:
GearPart Script: https://pastecode.io/s/4cxcn07k (Used for changing positions of the tiles(gears))
GridSetup Script: https://pastecode.io/s/5w4ak6ky (Setting up background grid)

[frail dust]

The specific code I am facing the error is this

    {
        if(swipeAngle > -45 && swipeAngle <= 45 && column < grid.width)
        {
            //right swipe
            otherGearPart = grid.allGearParts[column + 1, row];
            otherGearPart.GetComponent<GearPart>().column -= 1;
            column += 1;
        }

        else if (swipeAngle > 45 && swipeAngle <= 135 && row < grid.height)
        {
            //up swipe
            otherGearPart = grid.allGearParts[column, row + 1];
            otherGearPart.GetComponent<GearPart>().row -= 1;
            row += 1;
        }

        else if ((swipeAngle > 135 || swipeAngle <= -135) &&  column > 0)
        {
            //left swipe
            otherGearPart = grid.allGearParts[column - 1, row];
            otherGearPart.GetComponent<GearPart>().column += 1;
            column -= 1;
        }

        else if (swipeAngle < -45 && swipeAngle >= -135 && row > 0)
        {
            //down swipe
            otherGearPart = grid.allGearParts[column, row - 1];
            otherGearPart.GetComponent<GearPart>().row += 1;
            row -= 1;
        }
    }```

[knotty sun]

line?

[frail dust]

sorry, I meant code

or lines*

[knotty sun]

so which line?

[frail dust]

all the if conditions

the whole code I just highlighted

no matter where u swipe, same error

[knotty sun]

so it's obviously grid.allGearParts
debug the values you are using as indexes compared to the actualy lengths of the array

[frail dust]

the array isnt empty, it has 48 values which is expected

[knotty sun]

debug it

Debug.Log($"{grid.allGearParts.GetLength(0)} {grid.allGearParts.GetLength(1)] {column] {row}");

[quartz folio]

it's weird that a down stroke is a row modification

and it's also weird that it's column, row

Ah, never mind, I get why it's this way

[frail dust]

I get values on console like

i wonder why my row column values are in negative, thats another thing

[knotty sun]

not another thing, the root of your problem

[frail dust]

yeah ig.. but why they in negative

[knotty sun]

only you can answer that

[frail dust]

    {
        grid = FindObjectOfType<GridSetup>();
        targetX = (int)transform.position.x;
        targetY = (int)transform.position.y;
        row = targetY;
        column = targetX;
        Debug.Log($"{grid.allGearParts.GetLength(0)} {grid.allGearParts.GetLength(1)} {column} {row}");
    }

  
    void Update()
    {
        
        targetX = column;
        targetY = row;
     }```

This is how I set the row and column values

[quartz folio]

that seems very fragile

[knotty sun]

that's insane

[quartz folio]

the way you set positions isn't directly related to the index

[frail dust]

yeah i thought so

[frail dust]

so the problem lies in the transform.position.x and y?

[knotty sun]

no, the problem lies in the way you are using them or expecting their values to be

[frail dust]

So its making it into INT and setting my index as negative

[frail dust]

can you help and elaborate?

I am totally new into match type games

[knotty sun]

omg, can you not see the difference between the position and the name ?

[quartz folio]

The GridSetup should reference and spawn a component (e.g. GridItem), and set a variable that describes its coordinates/indices.
Instead you're spawning a GameObject, setting a Transform to be in some position, and are reading that transform hoping that it's the same as the indices.

[frail dust]

nope sorry...

[quartz folio]

You need strong references to real values, not vague references inferred through a component that describes something different

[frail dust]

yeah

[knotty sun]

(0,1) != -1.7, -3.3

[frail dust]

ah that? Yea I saw that

[knotty sun]

so, that is your problem, surely a gameobject with the name (0,1) should have a position (0,1), or not?

[faint quest]

how i could disable collison betwen paritcle 2d and some collider 2d?

[frail dust]

yeah it shall have same index as name

with same position

otherwise even if it would swipe, it would set the position wrong

I understand the root of problem now

Thanks @quartz folio @knotty sun ..... Although I have to think more on how to solve this issue.. So I will try this by myself and update it here if any issues

[knotty sun]

it's pretty simple, set the gameobject positions correctly

[frail dust]

yeah

[stable osprey]

u so old 😆

[frail dust]

im the og

[stable osprey]

true

[frail dust]

so, if im stuck on a problem and im slow to understand, pls dont judge Xd

[stable osprey]

I remember back in the day I was 12 and was sending pretend-angry emails to internet explorer team, and was getting back a response from humans lmao

[frail dust]

haha

[knotty sun]

lol, unlikely, I'm THE og

[frail dust]

agreed, ur pfp looks older than mine

[knotty sun]

That's because it is, it was around long, long before IE was even thought of

[vivid heart]

Hello, I have a 3D character with animation and movement through physics. Could you please tell me how to make it so that even if the character bumps into a wall, they can slide off it?

[broken lynx]

Anyone know how to fix this?

[soft shard]

Easiest way would be to apply a PhysicsMaterial to your rigidbody if your using one, otherwise you could raycast toward the object you bump into and move along its normalized angle (which would require a bit of math)

Not quite sure why that would happen, maybe you have the wrong transform referenced in hipFirePosition? Also, Update will only run if the script, and the object that script is attached to are both enabled, so your if-statement gameObject.activeSelf would always be true if your Update is ever running anyway

[fresh cosmos]

im working on a tool for loading multiple scenes. and im struggling with figuring out the correct way to check that a scene has finished loading and is enabled. sicne if i want to replace all my scenes i need to load them first then unload the old ones as there needs to be at least a single scene at all times.

loadingOperations is a list of AsyncOperations which is what SceneManager.loadSceneAsync(SceneName); returns

public bool getIsComplete()
{
    for (int i = 0; i < loadingOperations.Count; i++)
    {
        if(!loadingOperations[i].isDone)
            return false;
    }
    return true;
}

this is what i tried but it seems like even though scene activation is true doesnt mean it is active yet. so what should i be checking instead?

and isDone apparently doesnt mean its active yet

[knotty sun]

UnloadSceneAsync ?
Also go and read the docs

[fresh cosmos]

yeah im loading scenes async

thats kinda the point

[knotty sun]

not in that code you are not

[fresh cosmos]

sure ill have a look, been a while since i looked at this doc

according to it isDone should be when its finished so idk what else you want me to look at

i guess i could use the completed event but it should be the same thing right? one just invokes an event

since i originally was only checking !loadingOperations[i].isDone but it didnt wait until it was actually active

[fresh cosmos]

im not getting that on the page i was one https://docs.unity3d.com/ScriptReference/AsyncOperation.html

[knotty sun]

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

click through

[fresh cosmos]

that doesnt seem right though, cuz my scene is clearly not active but it passes the check still

[knotty sun]

I dont understand why you would be checking the AsyncOperations generated by UnloadSceneAsync in a loading sequence

[fresh cosmos]

what other option would i have?

if i want to load scenes asynchronously isnt that literally the only option?

[knotty sun]

LoadSceneAsync

[fresh cosmos]

which returns an async operation...

[knotty sun]

Unload is the opposite of Load

[fresh cosmos]

yeah i am aware

i am making a tool to make it easy to load and unload collections of scenes

[knotty sun]

So why would you think the same AsyncOperation used for the Unload would work for the Load?

[fresh cosmos]

so if i want to load a collection, i need to load it first, have it be done loading, enable the scenes, then unload the ones i dont want

[knotty sun]

I have no idea why you would want to do that

[fresh cosmos]

oh sorry, i think i miss wrote something. i am using loadSceneAsync. which i want to wait to comeplete then unload

[knotty sun]

omg, I only pointed it out 3 times

[fresh cosmos]

i didnt understand thats what u meant cuz i know what i meant lol

but that doesnt change the issue. its passing the isDone check while its not done

[fresh cosmos]

here you can clearly see that the "testUI" scene is not yet enabled but while checking its AsyncOperation.isDone it passes the check as how i have said before

and you can see that because its passing the code is attempting to unload the other two scenes which should not unload yet

so idk why it is passing the check

ok i found the issue, it seems like the operations wasnt passed properly and so the list was 0

[final fox]

Just build a playable version of my game and it runs fine on 3 PCs but on the 4th they get this error:

The only noticeable difference is that the 4th PC has W11 whereas the others are W10, but I don't think that should be the issue

[somber nacelle]

that's not a code question. but are you even certain that is the only difference?

[final fox]

My bad, which channel would be appropiate? Is it Unity talk? Also it probably isn't but that's the only noticeable one.

[somber nacelle]

use #🔎┃find-a-channel to find the most relevant channel for your question

[fair osprey]

I have some code that I only want to start executing after a UI Element is being drawn but if I execute that code in the OnEnable() of the UI element the script is on it actually starts executing before the UI Element visually appears

any advice on how I can guarantee it only executes once it's visible and not just technically enabled?

(it also starts executing the code before drawing the element fully if I just do gameObject.SetActive(true) and FunctionToRun() in consecutive lines within the same method)

[native flower]

Question: Where all can script data be set? I know this sounds simple but it's not. I have a game project i was given to make work and i have a public gameobject array that is repeatedly accessed by scripts but in neither ANY script nor anywhere in the scene (I've searched the scene file with a text editor) can i find any assignment of any data to this variable.
When compiled there is a working game but for the life of me I cant figure out where data would be assigned. I've searched all .asset files and prefab files for references to the script as well.

[mossy snow]

default values for serialized fields can be put on the script assets themselves (that data is stored in the meta file associated with the script)

[somber nacelle]

those values would then also be in the meta files for any prefabs or the scene that the component is in because they are serialized just the same as any other serialized field

so if they've actually searched the scene that these components exist in and didn't find that data, then it's very likely being assigned in code

[thick terrace]

what's the actual problem this is causing? normally everything gets rendered at the end of the frame after LateUpdate, but is there a reason you actually need it to be on screen or do you just need the layout for it?

[fair osprey]

it's a complex math calculation that takes upwards of 30 seconds

so Id like to turn on a screen overlay indicating its working before it starts

[thick terrace]

i'd say you probably want to do it one frame later then, since even WaitForEndOfFrame is before rendering iirc

[fair osprey]

how would I go about forcing it to do that?

[somber nacelle]

sounds like something that should be on another thread (either using a Task or the Jobs system) to ensure you aren't blocking the main thread so that your visual indicator can appear and you also don't prevent the entire rest of your game from freezing

[thick terrace]

you could use a coroutine or awaitable and yield return null or await Awaitable.NextFrameAsync, respectively

sounds like something that should be on another thread
yeah, if this is suitable for what you're doing eg not targeting WebGL and not doing anything that needs Unity APIs, you can easily throw it on another thread and have unity wait with something like this:

async void LoadExpensiveStuff() {
  ShowLoadingUI();
  await Task.Run(() => { calculate expensive stuff });
  HideLoadingUI();
}

[fair osprey]

gotcha

yeah I suppose Im doing stuff that needs Unity API

[fair osprey]

so this solution is out I suppose

[thick terrace]

try a coroutine then, if you yield once before you do anything it'll start doing work on the next frame

[fair osprey]

yeah just trying to wring out of my brain how to do coroutines again

its been a while and its late

[somber nacelle]

what exactly are you doing?

[fair osprey]

positioning graph nodes

using laplacian embedding

I need eigenvectors

ok my brain is hella frazzled fuck

[somber nacelle]

Do you actually need to access the transforms throughout that entire process? Can you not get whatever data you need from them at the start then do your calculations?

[fair osprey]

technically probably yes

I was not very smart when structuring these methods

ok here's the idea

draw UI element -> do all the eigenvector stuff async -> after it's done do the unity internal stuff like positioning -> hide UI element

[warm cosmos]

if I translate an object by Vector3(1.0, 0.0, 0.0), would that be a meter? 1 unity unit?

[somber nacelle]

1 meter in physics is 1 unit of world space

[somber nacelle]

Yes, this is pretty much what I was suggesting

[fair osprey]

seems to work

now Ill just have to eventually figure out how to animate the ui element while the other operation is running

[rose willow]

how do I use fog with unlit materials?

[cosmic rain]

You don't. You'd need a custom shader for that.

[fervent coyote]

Henlo, I was wondering if someone could help me with something-
I want to create an automatic way of rendering my world map, hopefully via an editor function. What it would do is take a camera, and several gameobjects, and iterate the camera going to each game objects position, render the area, and save it to a file. I plan for 16 positions to get renders from (The camera is also an orthographic projection)

I just need to find a way to actually render information, and this is where I need help from. Anyone got any ideas or tips?

[rigid island]

all you need is to call the Render function into a render texture then from there decide what to do with it

[fervent coyote]

Ah ok

I thought of that, but I was thinking if maybe there was something else

[vapid zinc]

I need some help, I'm very new at game development also programming

I tried to make my Visual Studio more minimalist but I stumble upon this section of visual studio, how can I remove this column.

please let me know if this out of topic.

[rigid island]

eh not really a unity code question, that's icon for showing your class inheritance . Something helpful, would suggest you keep it.

[vapid zinc]

I see, thank you very much 😊✨

[rigid island]

here you go

[vapid zinc]

Whoaaa, thank you ✨

[dusky tulip]

is it possible to have this line of code call the scriptable objects from a folder to automatically show up instead of adding them manually?

[rigid island]

https://docs.unity3d.com/ScriptReference/Resources.LoadAll.html

not really "automatic" but you can certainly make it so with a few lines and maybe OnValidate/Reset or something

[merry stream]

should I use the new input system for UI interactions or stick with the IDropHandler, IPointerDownHandler, etc and check for things like PointerEventData.InputButton.Left? just trying to figure out what most people use

[rigid island]

those interfaces still use event system , they shouldn't be affected (assuming you changed InputModule to new one)
unless you mean some other type of interaction?

[merry stream]

yeah but say I want to let the player change the keybinds for the UI instead of hardcoding Input.GetKey(F) for example

[rigid island]

for like navigation or something ?

[dusky tulip]

got it solved

[merry stream]

maybe like using the item for example

in an inventory

[rigid island]

just so you aware you can't build with this class unless you have it palced in the Editor folder or use the proper precompile conditionals

no idea why you're doing it this way tbh. Resources class is easier..

using Start method for this is silly when you can just make it happen in the inspector directly

creating extra overhead at runtime for no reason not like it will work in a build anyway in your case

[dusky tulip]

Oh

I'll just add em manually

[rigid island]

Ohh sure then make a UI only control scheme but you should still be able to use those interfaces

[rigid island]

that also works.
btw could've just done

MyAwesomeSO[] myawesomes;
private void OnValidate()
{
    var mySOs = Resources.LoadAll<MyAwesomeSO>("awesomeSOFolder");
    if(mySOs.Length != myawesomes.Length)
    {
        myawesomes = mySOs;
    }
}```

Is there anywhere I could find information on actually setting up steam integration? I have set it all up, gone through the documentation a thousand times, googled around but I can't seem to be able to consistently get the steam overlay to appear, and the api call I expect to open the marketplace...just isn't

How to handle addition/subtraction on very distant numbers for incremental game

Is there anyway to force an update with regards to content size fitters, layout groups, etc? Im trying to grab the size of an object in code but it seems like the size isnt being updated on Start

nvm its LayoutRebuilder.ForceRebuildLayoutImmediate

[frail dust]

I have an issue where the value of rows and columns are not transferring to another script in the same GameObject. Whenever I debug the rows and cols in the script GearPart, it shows 0 0 for rows and columns. But the script GridItem which is assigning the values is working fine. The same value of rows and cols are not getting read by the GearPart script somehow.

GearPart script:

{
    private GridItem gridItem;
    public int column;
    public int row;
   
    void Start()
    {
        grid = FindObjectOfType<GridSetup>();
        gridItem = GetComponent<GridItem>();
        column = gridItem.col;  // Use the GridItem's column
        row = gridItem.row;  // Use the GridItem's row
        Debug.Log($"{column} {row}");
    }
}

GridItem script:

{
    public int row;
    public int col;


    void Start()
    {
        string name = gameObject.name;
        string pattern = @"\d+";
        MatchCollection matches = Regex.Matches(name, pattern);
        if (matches.Count > 0)
        {
            int firstNumber = int.Parse(matches[0].Value); // First integer
            int secondNumber = int.Parse(matches[1].Value); // Second integer

            col = firstNumber;
            row = secondNumber;
        }

    }```

[knotty sun]

int is a value type not a reference type

[frail dust]

but im referring the the value of GridItem script

        row = gridItem.row;  // Use the GridItem's row```

[knotty sun]

irrelevant, you are making a copy of the values in row and column at that time

[thick terrace]

are row and col set to 0 in the editor before you play? it looks like they're being populated in Start, in which case you're depending on the scripts updating in a certain order

[knotty sun]

also that ^

[frail dust]

uhm they get instantiated at runtime only. But yes they are set to 0 0

[frail dust]

so how shall i approach

[knotty sun]

do not store row and col locally and always use gridItem. to get the value

[frail dust]

I tried calling in awake() in the former script, but it didnt fix the issue

[thick terrace]

you could just set the script execution order so that GridItem runs first then, but it'd probably suggest reworking it so you don't depend on two Start methods being called in a specific order

[frail dust]

I tried calling it in Update() to check if there is some execution order playing out, but nope the issue persisted

[thick terrace]

to do it that way you'd need to change GearItem.Start to GearItem.Awake, not the other way around

[frail dust]

Yup thats what im talking about

[thick terrace]

can you put in debug log so you can see that GridItem's setup code is definitely running first?

[frail dust]

    {
        Debug.Log("GRID ITEM STARTED FIRST");
        string name = gameObject.name;
        string pattern = @"\d+";
        MatchCollection matches = Regex.Matches(name, pattern);
        if (matches.Count > 0)
        {
            int firstNumber = int.Parse(matches[0].Value); // First integer
            int secondNumber = int.Parse(matches[1].Value); // Second integer

            col = firstNumber;
            row = secondNumber;
        }
    }```

Output: Yes it did

GridItem is getting called first

But whatever value it sets, it doesnt get to the other script

which is in the same gameObject

[vivid heart]

hello how to make staris climb? 3d person controller

[frail dust]

Changing script execution order in project settings also didnt fix it

[knotty sun]

that output is meaningless, you have no idea if your if statement is true or false and if col and row are even being set to something

[frail dust]

what debug shall be used instead?

[knotty sun]

inside the if, debug col and row

[frail dust]

Thats showing the correct values

But the other script isnt setting those values

GridItem script properly sets the rows and columns.
GearPart script shall get that value and set it to its local variables, but its setting them as zero

Person A is doing the right thing and telling it to person B, but somehow person B is not getting the information

[knotty sun]

ok, so debug,log the instanceid of the griditem script and the griditem reference in the gearpart script

[frail dust]

Wait, Something is weird.. I debugged and got to realize that the condition is not getting true

       {
           int firstNumber = int.Parse(matches[0].Value); 
           int secondNumber = int.Parse(matches[1].Value); 

           col = firstNumber;
           row = secondNumber;
           Debug.Log($"{col} {row}");

       }```

so its setting the values to 0

[knotty sun]

so this was BS then

[frail dust]

it wasnt like this earlier

[knotty sun]

how would you know, you just added the debug to check it

[frail dust]

Yesterday when I did the debug, it was setting the correct values

The string is of prefab'

Not the gameObject's name

Thats the issue

string name = gameObject.name;
What do I do?

[knotty sun]

Awake is being run BEFORE you set the name

[frail dust]

yes

[knotty sun]

this is why you dont use names as data, find a beter way

[frail dust]

Problem fixed

[knotty sun]

it's still a crappy and very britle solution

[frail dust]

yeah im in a bit of hurry so did what came to my brain

Jesus Im facing the index error again, after setting the indices correctly

[knotty sun]

just turn the Awake into a public method taking a row and col then call it after the instantiate

[frail dust]

Also even if some items get swiped, they are getting to wrong random positions

[frail dust]

Lemme do it

[knotty sun]

you do, after all, have the row and col values when you Instantiate

[frail dust]

I mean if its working why to change it though

I did change the script execution order and now its setting the values correctly

[knotty sun]

you do you but don't be surprised when implementations like that come back and bite you in the arse

[frail dust]

I understand that

[frail dust]

This is the issue im facing rn though

[knotty sun]

so where is the debug we put in yesterday?

[frail dust]

sorry what debug?

Yesterday the problem was that rows and columns were getting the values of transform.position. So I rn changed it to instead get the value from gameobject's name using regex

[knotty sun]

you are not going to tell me that I remember your code better than you do?

[frail dust]

So the index out of error is not the issue anymore. The issue is the movement of the tiles, they are getting moved with the unity's screen space dimensions, not like a row above, or a column below

What I suspect is this line

   targetY = row;```

This is moving the current tile to that column's/row's value.
Like if c=2, r=2
Its moving the current tile to that (2,2) in screen space terms. Instead it should be moving the current tile to the tile which has the name (2,2)

Since my positions are way different to what names I have given to my tiles

I gotta change how they move

    {
        

        if (swipeAngle > 0)
        {

            targetX = finalTouchPosition.y;
            targetY = finalTouchPosition.x;

            if (Mathf.Abs(targetX - transform.position.x) > 0.1)
            {
                //Move Towards target 
                tempPosition = new Vector2(targetX, transform.position.y);
                transform.position = Vector2.Lerp(transform.position, tempPosition, 0.4f);
            }
            else
            {
                //Directly set the position
                tempPosition = new Vector2(targetX, transform.position.y);
                transform.position = tempPosition;
                grid.allGearParts[column, row] = this.gameObject;
            }

            if (Mathf.Abs(targetY - transform.position.y) > 0.1)
            {
                //Move Towards target 
                tempPosition = new Vector2(transform.position.x, targetY);
                transform.position = Vector2.Lerp(transform.position, tempPosition, 0.4f);
            }
            else
            {
                //Directly set the position
                tempPosition = new Vector2(transform.position.x, targetY);
                transform.position = tempPosition;
                grid.allGearParts[column, row] = this.gameObject;
            }
        }
       
    }

    private void OnMouseDown()
    {
        firstTouchPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        
    }

    private void OnMouseUp()
    {
        finalTouchPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        CalculateAngle();
    }```


This looks better. I am directly making the target point to the positions recorded by mouse clicks

Instead of setting the values of column and rows to my target positions (I was delusional I agree)

[soft shard]

Most games will use ramps as a collider for stairs, so it becomes a slope calculation (which can be easier than deciding "what is a step, what is a wall") - if you prefer actual step collision, you could try making your steps small enough to climb over or angle them slightly and if you prefer more realistic stairs, maybe you can try looking up tutorials on step-up logic, for example this may be a good one: https://www.youtube.com/watch?v=ILVUc_yV24g

Hi ! Questions about ScriptableObject. I may be doing it wrong, but currently, I call ScriptableObject.CreateInstance() and before I can initialize the content of my new SO, OnEnable is called, which is not what i want. So my questions are:

• Is it possible to have something execute in between CreateInstance and the OnEnable ?
• If not possible, is there a better alternative to do so ?

[thick terrace]

i guess Awake runs first? but generally it's best to avoid putting stuff in OnEnable that requires other code to run first if possible, could you maybe make an initialization method you call yourself?

[leaden ice]

Why do you need OnEnable to run later?

[tired elk]

Imposed by my colleagues' current structure. They do some initialization shenanigans. I wanted to know if there was a way without altering this, but I will discuss with them if we can find an alternative.

[thick terrace]

you could do something like put a static event property in the class that gets invoked at the start of OnEnable, but that's pretty nasty 😄

[leaden ice]

you probably want to alter it

[tired elk]

On my side, I have a json file I deserialize that fill the different fields which, well, are required by the initialization that happens in the OnEnable

But I think I can't do a FromJson for a ScriptableObject and must use FromJsonOverride which requires me to instantiate a new instance first etc.

[placid summit]

this at runtime or in editor?

[tired elk]

Both actually.

I mean, the json deserialization happens at runtime, but the scriptable object type is used in both editor and runtime.

[placid summit]

what is the use case of json deserialization in a scriptable object?

[tired elk]

Not final design but the json file is supposed to be a mod that overrides gameplay data contained in scriptable objects.

Not like I edit the scriptable object, but i generate a new scriptable object from the json that will be used instead of the vanilla one

[placid summit]

I see - but maybe the scriptable object could just contain a class of data and json deserialises into the same type of class - and you abandon the scriptable object once whatever you need is read in! scriptable objects are an odd creation that is a monobehaviour underneath - more useful for holding Unity types. So depends what you hold in it

[tired elk]

I suppose that would work but that would require quite the refactor of our current code haha

I think it will take us less time to have our initialization not rely on OnEnable. I'll discuss it with my colleagues

[placid summit]

yeah anyway I dont know the original answer!!

[tired elk]

Thanks for the idea anyway. that's the issue with features that come a little late in development, sometimes it's not compatible with the structure of the game 🥲

[somber nacelle]

that error is not related to your code (unless you're writing custom editor code that uses the graph editor). closing the animator or whatever other graph editor window you have open should prevent it from appearing for a while, but you can also just clear it from the console and move on

and be more specific than "don't work"

it just don't do what it is supposed to

it is supposed to make the boss turn around to make him go towards me

[naive swallow]

Is there a better way to replace every material on a MeshRenderer with a single specific one than looping over renderer.materials and setting each element of the list? Some sort of helper method I'm not finding somewhere?

[somber nacelle]

MeshRenderer.SetMaterials lets you pass a list of materials to assign

[rigid island]

haha you would think right? I had to do the same with ProBuilder not converting well from BIRP to URP

[naive swallow]

I'd still need to build a list of multiple instances of the same material with the same length, right? I guess that's better but that still feels wrong

[somber nacelle]

yep

you could just write an extension method that does the work for you so you don't need to repeat that process anywhere though 🤷‍♂️

[naive swallow]

Dangit it's 2022+ and this project's still on 2021

[flint needle]

Wondering, how do i profile load times?
Every tutorial i see online talks about spikes in performance, which i dont have.
How do i know why my game is taking so long (7-10 seconds) to load one scene?

[mellow sigil]

You profile it the same way as everything else. The load time is the "spike"

[flint needle]

I dont really understand, this is what i get on target platform

On my PC its just the 10 secs down to almost instant

but the spikes are still there, which i thought was to expect as its load / unload

Worth mentioning its an Async load, so in between there´s a load screen

[mellow sigil]

Look in the hierarchy what causes it

[flint needle]

Thats what i dont understand, the hierarchy is per frame, how do i know what is holding the load that much time?

[mellow sigil]

Look at the frames inside the load time

[rigid island]

you have to like select the spike

check / sort by the .ms

[mellow sigil]

Or change it to synchronous scene loading, then you can see what it does during the entire time

[flint needle]

Isnt it normal to have a single spike on unload / load?

[rigid island]

well yeah its very probable, especially if you are creating objects

[flint needle]

Its just regular loading of a scene, no instantiate or anything

[rigid island]

remember even when you unload you're doing the opposite operation, you still have to cleanup the same memory you allocated

[rigid island]

objects still get created / destroyed on scene load/unload

[mellow sigil]

Scene loading is literally just instantiating the objects that are in the scene

[flint needle]

just pointing out im not actually instantiating on runtime other than the scene

[mellow sigil]

makes no difference

[flint needle]

What are your suggestion sorry?

[rigid island]

did you actually check the spike ?

like put your cursor on it (click it)

[flint needle]

surely

[rigid island]

and what does it say , sort it by ms . What is causing most delay

put Deep Profile if you must

[flint needle]

Semaphore wait for signal

[mellow sigil]

#archived-code-general message do this and you can profile the entire scene loading

[flint needle]

But do i have to revert the way i load unload every time i have an issue with loading times?
There should be a way for me to profile this accordingly without changing the loading structure

[mellow sigil]

Maybe there is, but I don't know of it so that's the only advice I can give

[flint needle]

I have changed it and while the profiler looks cleaner, the transition seems slower.
In any case im still uncertain with where to look at

Like how do i know why this wait is here

[mellow sigil]

If you load the scene synchronously it should all happen within one frame. What unload is that and how do you know it's caused by unload?

[flint needle]

You´re right, it wasnt totally async yet. I can now see a single spike only, the "Load" one

So i should simply focus on optimizing this load frame spike to fix the waiting time i pressume?

[shy sentinel]

I'm a beginner with some basic knowledge of C# and looking to learn Unity. Where should I start? Should I follow Brackeys?

[mellow sigil]

Well yeah, whatever is causing it is now in that single spike

I have another question about debugging, at some point my console debug changed its structure for a more "in-depth" stack trace, which for me its a bit unnecesary and harder to read.
Is there any parameter to avoid this?

[cold parrot]

Did you change player settings to produce ‚full‘ stack traces? These look like memory addresses you would get in a IL2CPP build with full traces

[flint needle]

Oh! It seems i must have changed it? i dont recollect doing it, but thank you! 😄

I have a bullet that is phasing through my objects. Now I have rb to continuous but that's not the issue. My rigidbodg is interpolate for the bullet that's why it phases and it doesn't phase all the time only like q out of 5 to 6 shots completely at random

Reiterating it's to do with interpolation just don't know hoe to fix it

Are there preprocessor directives for URP and HDRP?

[hasty plinth]

Hi, I have been trying for some hours now to make some data files continue existing when I build the game , and then still be able to access them while playing the game on android.
I am using the BinaryFormatter that Brackeys showed in his video:https://youtu.be/XOjd_qU2Ido?si=ry4HJe0hz_ivOGvS
To save some stage data on a set of files.
I found out that if I save them on the StreamingAssets folder they will remain intact when buildig the game and I will be able to access them from inside the game.
I later found out that Android does not let you access those files through code and I will need to use UnityWebRequest to do so.
The problem is that I have no clue how to implement it to my already existing code as

1. My data is saved in Binary, and
2. I currently save my data with my own data type StageData and I don't know how to convert the data from binary to StageData

My question is, is there an easy way to make this almost working system work for android, or should I just scrap it and use different way?

[wheat cargo]

You'll need to use UnityWebRequest to get the file and deserialize the binary data with BinaryFormatter. Also I don't recommend using BinaryFormatter

They removed it in .NET 9 which Unity will eventually reach (not for quite a while though)

[leaden ice]

no because it can thoeretically chaane at runtime. Use https://docs.unity3d.com/ScriptReference/Rendering.GraphicsSettings-currentRenderPipeline.html

[wheat cargo]

Who in their right mind would ever change render pipelines at runtime lol

[celest vault]

would anyone happen to know whether it's possible what version of the .net runtime the game uses after compilation? like just from the files?

[hasty plinth]

Well I only needed it to store only a little bit of data, so I figured I would use this. But after searching it up a bit now I have come to the same conclusion as you.

[calm mountain]

So buttons have onclick, but is there an easy way to do OnHover?

[wheat cargo]

If you want to keep the data in binary, look into MemoryPack by Cysharp

otherwise just use something such as json or xml

[hasty plinth]

I will probably use the latter as I have no real reason to keep them in binary

[soft shard]

You could use pointer event handlers: https://docs.unity3d.com/2018.2/Documentation/ScriptReference/EventSystems.IPointerEnterHandler.html

[bitter warren]

no.. :x

[wheat cargo]

In case your curious, this code should work with what you have:

async void Start()
{
    byte[] fileData = await LoadFileAsync("myfile.bin");

    BinaryFormatter bf = new BinaryFormatter();

    using MemoryStream memoryStream = new MemoryStream(fileData);

    StageData stageData = (StageData)bf.Deserialize(memoryStream);
}

async Task<byte[]> LoadFileAsync(string file)
{
    string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, file);
    UnityWebRequest request = UnityWebRequest.Get(filePath);
    await request.SendWebRequest();

    if (request.result != UnityWebRequest.Result.Success)
    {
        throw new System.Exception("Failed to load file");
    }

    return request.downloadHandler.data;
}

[wheat cargo]

Which UI framework, UGUI or UI Toolkit?

[calm mountain]

I was just using the regular buttons. Had a highlight color, so I was curious if it had an event for hovering

[wheat cargo]

It does not, but you can make your own button class and inherit from Button and add it yourself

[rigid island]

use event Trigger

or inside code you can use the IpointerEnter/Exit interface

[wheat cargo]

Yeah event trigger would be simpler, downside is you have to add it to every button where you want that functionality. A prefab can solve that problem though

[hasty plinth]

The type or namespace name 'Task<>' could not be found

[wheat cargo]

Include System.Threading.Tasks

[hasty plinth]

'UnityWebRequestAsyncOperation' does not contain a definition for 'GetAwaiter' and no accessible extension method 'GetAwaiter' accepting a first argument of type 'UnityWebRequestAsyncOperation' could be found

(sorry for just throwing you errors, but I have never even seen most of the stuff you wrote so I don't know how to fix them)

[wheat cargo]

Ahh I'm using Unity 6 and they can be awaited. I can convert it to coroutine for you hold on

[hasty plinth]

line 16 here

[wheat cargo]

StageData _stageData;

void Start()
{
    StartCoroutine(LoadStageData("myfile.bin"));
}

IEnumerator LoadStageData(string file)
{
    string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, file);
    UnityWebRequest request = UnityWebRequest.Get(filePath);
    yield return request.SendWebRequest();

    if (request.result != UnityWebRequest.Result.Success)
    {
        throw new System.Exception("Failed to load file");
    }

    byte[] binaryData = request.downloadHandler.data;

    BinaryFormatter bf = new BinaryFormatter();

    using MemoryStream memoryStream = new MemoryStream(fileData);
    _stageData = (StageData)bf.Deserialize(memoryStream);
}

[wheat cargo]

I forgot to add the StartCoroutine call, it's there now

[robust mantle]

I want to include an executable called yt-dlp which you can use in command prompt with the exe in the folder or path file but I dont know how to actually use it in unity, how do you?

[wheat cargo]

If you'd rather use Tasks (I prefer them), you can follow this for versions that don't have native support for awaiting AsyncOperation

https://discussions.unity.com/t/make-all-asyncoperations-awaitable/858623

Or install UniTask by Cysharp

[wheat cargo]

You need to use the Process class

https://learn.microsoft.com/en-us/dotnet/api/system.diagnostics.process?view=netstandard-2.1

[robust mantle]

ty

another question

I have colors that need to be changed on multiple different types of components from TextMeshProUGUI to like Images, is there a way to have a generic component class and change the color property or is that undefined dangerous behavior and no do

[robust mantle]

also do I need to worry about killing the process on unity play exit or will it do that for me?

dont get me wrong it wont execute for more than a few seconds but im not sure how it works

[wheat cargo]

I believe it will close when your app closes, but I am not 100% sure

[robust mantle]

ah okay

I can just not do it headless to check right

[wheat cargo]

Yes, from what I'm reading I don't think it automatically kills it

[wheat cargo]

This adds a pointer enter and pointer exit event:

using UnityEngine;
using UnityEngine.Events;
using UnityEngine.EventSystems;
using UnityEngine.UI;

#if UNITY_EDITOR
using UnityEditor;
using UnityEditor.UI;

[CustomEditor(typeof(MyButton))]

    SerializedProperty m_OnPointerEnterProperty;
    SerializedProperty m_OnPointerExitProperty;

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

        m_OnPointerEnterProperty = serializedObject.FindProperty("m_OnPointerEnter");
        m_OnPointerExitProperty = serializedObject.FindProperty("m_OnPointerExit");
    }

    public override void OnInspectorGUI()
    {
        base.OnInspectorGUI();

        EditorGUILayout.Space();

        serializedObject.Update();
        EditorGUILayout.PropertyField(m_OnPointerEnterProperty);
        EditorGUILayout.Space();
        EditorGUILayout.PropertyField(m_OnPointerExitProperty);
        serializedObject.ApplyModifiedProperties();
    }
}
#endif

public class MyButton : Button
{
    [SerializeField]
    private UnityEvent m_OnPointerEnter;
    public UnityEvent onPointerEnter => m_OnPointerEnter;

    [SerializeField]
    private UnityEvent m_OnPointerExit;
    public UnityEvent onPointerExit;

    public override void OnPointerEnter(PointerEventData eventData)
    {
        base.OnPointerEnter(eventData);
        onPointerEnter.Invoke();
    }

    public override void OnPointerExit(PointerEventData eventData)
    {
        base.OnPointerExit(eventData);
        onPointerExit.Invoke();
    }
}

[wheat cargo]

I think you are manually going to have to track the process and kill it on application quit.

https://docs.unity3d.com/ScriptReference/Application-quitting.html

[hasty plinth]

Ok so it appears I will be needing some further assistance with my issue

[wheat cargo]

There is no great way of doing this tbh. They don't implement an interface which would essentially allow you to do this.

You could write something that checks the type of class and set the corresponding color field appropriately, but it'd be another component you'd have to add to everything and be pretty annoying

[hasty plinth]

I tried to use the Coroutine method but because my class does not derive from Mono Behaviour I couldn't use it without changing parts of others scripts.
So I went back to the first method and tried to use this method and I am running in 2 errors.

Here is my code: https://pastebin.com/p9d7PeH4

The first is this:
The type or namespace name 'TaskAwaiter' could not be found
but from what I saw online I need to update Unity in order to get it to work as I am using an old version

[wheat cargo]

You have to put the GetAwaiter method in it's own static class since it is an extension method

But honestly you should just add UniTask to your project

[hasty plinth]

The second is this Extension method must be defined in a non-generic static class and it appeared when I added the GetAwaiter method and I don't know how to fix it

[onyx walrus]

HI Good people. I have a short question: I am making an app that calculates the time. Should I use Time.DeltaTime or C# stopwatch? Which is more precise and resources friendly?

[wheat cargo]

Are you calculating simulation time or realtime?

[onyx walrus]

real time. It is an exercising app. It calculates countdown time for each exercise and elapsed for the whole session.

[wheat cargo]

Just install UniTask and add using UniTask; to your file and get rid of the GetAwaiter method

[hasty plinth]

I just did

[wheat cargo]

I mean you could use Unity's unscaled time or .NET time classes. Whatever is easier for you. They should both do the job

[onyx walrus]

thanks!!!

[wheat cargo]

You should change your method signature's from async void to async UniTask or async UniTaskVoid. You use the UniTask 90% of the time. Use UniTaskVoid when you are absolutely certain you won't have to await the call.

[hasty plinth]

I think I am starting to go crazy, but all the errors have finally cleared

[wheat cargo]

You should be awaiting where possible though

You should only use async void when you can't change the signature (i.e. an event from a GUI or a Unity message such as Start()

[hasty plinth]

Oh also it was using Cysharp.Threading.Tasks; not using UniTask; but I figured it out

[hasty plinth]

I also added that

[wheat cargo]

Yeah my b

glad you got it though

[wheat cargo]

You'd have to do something like this, which in my opinion is shitty but works.

using System.Collections.Generic;
using TMPro;
using UnityEngine;
using UnityEngine.UI;

public class ColorSetter : MonoBehaviour
{
    public List<Object> targets;

    [SerializeField]
    private Color _color;

    public Color color
    {
        get => _color;
        set
        {
            _color = value;

            foreach (var target in targets)
            {
                if (target is TMP_Text tmp)
                {
                    tmp.color = _color;
                }
                else if (target is Image img)
                {
                    img.color = _color;
                }
            }
        }
    }
    
    private void Start()
    {
        color = _color;
    }
}

[hasty plinth]

My god thanks you so much

everything seems to be working fine

I spent so much time on this and it thankfully was not a waste

[wheat cargo]

No problem, hopefully it mostly made sense

[hasty plinth]

That was some deep c#, at least for my current level, but I managed to make some sense of it near the end

[wheat cargo]

I mean Unity uses it's own fork of the Mono runtime, why do you need the version?

[wheat cargo]

Yeah asynchronous code takes a while to wrap your head around, but once you understand it, it becomes a game changer

[wheat cargo]

Very good read imo:

https://devblogs.microsoft.com/dotnet/how-async-await-really-works/

[swift falcon]

Hi people, I have a problem with [SerializeReference] and List<>

One of my scripts has field B that can reference [Serializable] Class A
it also has a List<A>
however in the inspector say I delete and item from List<A> that was being referenced in the field B but the reference still remains despite it being deleted from the list.

any way to prevent that?

[wheat cargo]

Any particular reason you are using SerializeReference?

[swift falcon]

just for null type and because the class is a normal c# class

sorry to serialize null values*

[wheat cargo]

Just because it's removed from the list doesn't mean it'll get removed from another reference, you have to manually set the reference to null

[swift falcon]

ah i see

is there anyway to put override the remove button then?

or will that have to be a custom inspector kinda deal

[leaden ice]

Serializefield should be just fine

[leaden ice]

Custom editor

[swift falcon]

no its just I want there to only be one instance of the custom c# class so when I edit the reference field it also updates serialization in the list but when I use [SerializeField] it doesn't seem to update the serialization in the list

[wheat cargo]

Yeah because SerializeField is by value not by reference

[wheat cargo]

Instead of custom editor, you could use the OnValidate unity message to null out the reference if it doesn't exist in the list

void ScrollToBottom()
{
    Canvas.ForceUpdateCanvases();
    floatingScrollRect.content.GetComponent<VerticalLayoutGroup>().CalculateLayoutInputVertical();
    floatingScrollRect.content.GetComponent<VerticalLayoutGroup>().SetLayoutVertical();
    //floatingScrollRect.content.GetComponent<ContentSizeFitter>().SetLayoutVertical();

    floatingScrollRect.verticalNormalizedPosition = 0;
}

I have included commented out line, since it has same effect I think.
It doesn't work as you can see, the missing pixels come from a an object with buttons and its own vertical layout.
But H Delta matches correctly, is there a way to force layout to scroll to the bottom?
I can do it manually by using in game slider where y will equal H Delta and its perfect.
I want to achieve same result in code.

Whole object for reference

[wheat cargo]

Look at the code for scrollbar to see how it does it

[wheat cargo]

What is with the force update and layout calls? All you should need is to set the verticalNormalizedPosition

[warm cosmos]

how do I make things update in editor like the OnDrawGizmos function?

e.g. if I move a cube around, Debug.Log(transform) and other stuff

[rigid island]

depends what you're doing

OnDrawGizmos can also be a viable way to run code in editor

[warm cosmos]

more context: I am working on a chunk loading system, and spawn chunks based on a viewer location, I'd like to be able to call an UpdateChunks() function whenever I change the worldposition of a cube object i have in the scene

[rigid island]

don't think there is some type of transform moved event so you can poll it i suppose

[warm cosmos]

how would I poll it?

[rigid island]

put your own event for when position was changed from before

[rigid island]

for example you can check in the editor update like
https://docs.unity3d.com/ScriptReference/EditorApplication-update.html

eg
EditorApplication.update += OnEditorUpdate;
OnEditorUpdate you can check with the EditorApplication.timeSinceStartup for example to do your own polling time / delays by.
if(myCube.transform.position != previousPos) {OnPosChanged?.Invoke(); previousPos = myCube.transform.position;}

I think there is a better way to check but its slipping me right now lol

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

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

They do have this
https://docs.unity3d.com/ScriptReference/Transform-hasChanged.html
but last time I could not get it to work and forums is mixed on this

[warm cosmos]

ok thanks for the info, I will check it out

[undone dock]

hi all, does anyone know how to do a smooth unwrapping animation if I must use a scene transition? For example, I have a 3d dice model. When the user clicks on it, I want it to spawn a 2d 'unwrapped' dice model (basically a 2d uv map), but I want to animate the 'unwrapping' somehow. I'm thinking of spawning this unwrapped dice model in a separate scene to do some other work.

Should I use an additive scene for this? I'm not familiar with how to animate the unwrapping this, or basically best practices in this scenario.

[cosmic rain]

Maybe just animate it in blender?🤔

[cosmic rain]

As for the scene, it can either be an additive scene or a DDOL object.

[solid relic]

public void MouseLook(float recoil = 0)
{
    float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity;
    float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity;

    mouseY += recoil; // Apply recoil

    // Vertical rotation
    rotationX -= mouseY;
    rotationX = Mathf.Clamp(rotationX, -verticalRotationLimit, verticalRotationLimit); // Limit vertical rotation

    // Rotate the player based on mouse X
    transform.rotation = Quaternion.Euler(0, transform.eulerAngles.y + mouseX, 0);

    // Calculate target rotation for the camera
    Quaternion targetRotation = Quaternion.Euler(rotationX, transform.eulerAngles.y, 0f);
    playerCamera.transform.rotation = Quaternion.Slerp(playerCamera.transform.rotation, targetRotation, Time.deltaTime * 10f);

    // Update camera position to follow the player with a slight offset
    Vector3 targetPosition = transform.position + new Vector3(0, 0.5f, 0);
    playerCamera.transform.position = Vector3.Lerp(playerCamera.transform.position, targetPosition, Time.deltaTime*10f);
}

Can someone please give me feedback on this method please?

[cosmic rain]

The lerp/slerp is incorrect. Aside from that, looks ok.

[solid relic]

for the rotation and the position of the camera?

[cosmic rain]

Yes. I don't see any other lerps in the code.

[solid relic]

both of them though?

[cosmic rain]

Both

[solid relic]

alrighty, i'll fix it up and let you know how it goes

[cosmic rain]

I assume that you understand what's incorrect with them, since you never asked for a clarification.😅

[warm cosmos]

any way it's possible for multiple quads to use the same material but different textures?

got this problem where I'm trying to make chunks of a noisemap but they are all displaying a single texture

do I need to make a material for each quad

actually, this is probably best done with a shader. ignore me

[solid relic]

Yeah sure aha, definitely 😂 I don't, i was just going to see what might be wrong

i'm guessing i should be using a variable for the "to" in them instead of a temporary one?

[cosmic rain]

The third parameter is wrong. It should be going from 0 to 1, as well as first and second params shouldn't be changing over time.

Basically, lerp doesn't suit this use case. Maybe use MoveTowards or something similar.

Also, check the docs.

[solid relic]

They shouldn't be changing over time? It starts at where the camera is, and then it gets lerps/slerps to the player position

[warm cosmos]

I want to work on things in the editor but if I create an object or something in code, the editor will leave it in the scene if I go and modify my scripts

And then create another object etc

How do I avoid this problem

[cosmic rain]

It does change though, as it lerps. Every frame playerCamera.transform.position would have a different value, would it not?

[solid relic]

"as well as first she second params shouldn't be changing over time" ?

[cosmic rain]

Yep. The first and second parameter shouldn't be changing over time, yet they change in your case. And the third parameter should be changing over time, yet it doesn't in your case.

[solid relic]

so which should be changing in my case, and which shouldn't be? I'm confused

[cosmic rain]

The first and second parameter shouldn't be changing in any case of lerp. And the third should. As simple as that.

Anything else is incorrect lerping.

[cosmic rain]

Might want to rephrase that question as I've no clue what you're asking.

[warm cosmos]

I gave up trying to make it work haha

[solid relic]

So how should i be lerping my players camera?

[sudden lantern]

How can I determine if the camera is inside a trigger? I don't want to add rigidbody and collider to the camera

[cosmic rain]

As I said, a, b - constant. C - changing from 0 to 1.
As for how you should be moving(not lerping) your camera, as I said earlier, MoveTowards is a better method for your use case.

[cosmic rain]

Why not?

You can check if it's position is in the bounds of the trigger, but that might get inaccurate depending on the context.

[sudden lantern]

I have a water surface with a trigger. I need to enable the underwater distortion effect if the camera is inside this trigger

[cosmic rain]

Well, an rb + collider sounds reasonable enough in this case..?

[sudden lantern]

bounds check gives me weird results..

[cosmic rain]

That doesn't tell me anything at all, aside from "yes no"

[sudden lantern]

well, if the camera is outside it tells - "no"
if the camera is inside it tells both - "yes" and "no"

[cosmic rain]

Well, then the camera position is getting in and out of bounds whenever you check that.🤷‍♂️

[sudden lantern]

no?

[solid relic]

The camera is in the water isn't it?

[sudden lantern]

it is

[solid relic]

That means it will give you "yes" and "no" from what you've said

[cosmic rain]

Debug it. The camera position as well as the bounds.

You're not gonna get far if you only rely on visual cues when debugging

[sudden lantern]

do I just need to check the position between frames

[cosmic rain]

You just need to see what's changing between frames and resulting in contradictory conditions.

[sudden lantern]

the camera position between frames is the same

same with the trigger

[soft shard]

Ae you logging the camera position and bounds when you get "no"? Or are you checking frames a different way?

[sudden lantern]

with IDE debugger

[soft shard]

Ah ok, so it sounds like your stepping through each frame manually then

Do you have multiple cameras in your scene that have this script?

[sudden lantern]

oh

no, I have only one camera, but the water surface script is checking the bounds

I need to check if the player is on the surface

[soft shard]

If you have multiple water surfaces with this script, its possible the "no" could be coming from the other instances, you could use the second param of Debug.Log to specify the object producing the log, when you click the log in the console it will point to the referenced object in your hierarchy

[cosmic rain]

Might want to debug it the same way you debug yes no for consistency.

[sudden lantern]

yeah, I've already realized that

thanks yall

[unborn elm]

Been thinkíng of add adding shoting line for my top down 2d game and trying line renderer for the first time. It seems like it can just render one component at a time and since its a monobehavior component I cant really just create 10 of them and use them for pooling in a single game object. Anyone has good way around this?

Guess just doing it in a sprite shader migth be best?

[steady hamlet]

Line renderer won't work?

Raycast line renderer

[unborn elm]

Line render work but would prefer not to create 100 line renders for 100 lines, seems very inefficient

Just would like one single object to take care of all line rendering

[steady hamlet]

Oh i thought it's only one line

[merry stream]

how do you guys typically handle updating UI when the gamestate changes? right now I'm just using an event system i made but its kind of messy, is there a way to easily data bind?

[soft shard]

Thats what I do, either a Pub/Sub global event manager, or I have the UI listen for events on the dependencies, then pull data from the dependencies public properties or pass the data as params to the event, I can represent a players health bar changing when they take damage or get healed this way, and decide to play an animation for it when the event is fired from the player

[dry sleet]

Hey guys,
I have walk and idle animations and I want to override the hands with other animations but some of them are one hand override and some are two hands override. Is there any other way to achieve it except creating 2 layers with one and two hands avatar mask ?

[soft shard]

If your mostly playing a state on the same layer and just need it to be a different animation for that state, you could use a Animator Override Controller asset, otherwise if you need each arm to be different, maybe its a question for #🏃┃animation

[dry sleet]

No different animations, as I said I want to override them on hands but for that I have to create 2 layers, one with one hand mask and the other two hands. I'm looking for a cleaner way to achieve that. Also I know Avatar Mask on animations is not suitable too.

[plucky inlet]

Anyone ever had the issue of assetbundles crashing unity, when instantiated? I get all the correct logs for the assets inside, but as soon as I uncomment the instantiate part, it just crashes Unity. I red from very old threads, that there were issues using loadassetasync multiple times?
https://pastebin.com/VpJQKSYw for sake of length

[soft shard]

Ah alright, didnt know if you already tried using an Animator Override Controller and what problems that gave you, it sounds like maybe it would be some kind of setup that would be done through the Animator window and largely without code, maybe the animation channel could have some ideas for that (or possibly others might see your question a bit later with some suggestions) - only one that comes to mind, with having 1 layer would be editing the second arm for your 1-h animations, but that may not be ideal

[dry sleet]

As I know Animator Override is for replacing animations with the same structure.
Thanks anyway.

[round violet]

i wonder why OnTriggerExit doesnt get called if i set the position of a gameobject with a collider outisde the trigger collider

[plucky inlet]

Because you set it, not move it there. Its like teleporting and ignoring physics entirely

[round violet]

could still be a extra param for that kind of checks

the collider still left the bounds

[plucky inlet]

And how should it check that efficiently? Check for ALL colliders in the whole scene everytime?

Imagine every collider will check for everything inside the scene even out of their bounds and not even close to. That game will give you some nice slideshow 😉

[round violet]

you could just check if the colliders inside last frame are still inside

UE made it work, so there is ways to do it, but Unity probably made some decision that make it to costy

[soft shard]

For that, the collision check would need to keep an active list of colliders and check them every frame, AFAIK this is essentially what OnTriggerStay does

[plucky inlet]

We do not want to start that comparison 😄 There are reasons each engine is doing it the way they do. but you gotta live with what you got. So either use physics engine or use your own event when moving things with position instead of physics to fire an event for example. You can always work your own system in parallel to physics to catch those special cases.

Maybe even what Dibbie mentioned might help you here to keep your own list of objects and just check, if they still are inside of it, if not, fire your custom event

[round violet]

yeah np im just wondering what internal work made it not handling this use case

[west lotus]

https://docs.unity3d.com/ScriptReference/Physics.SyncTransforms.html

[round violet]

thanks, will try that

[plucky inlet]

learn something new everyday, thanks for that insight 🙂

[round violet]

when does the engine call that by default ?

[plucky inlet]

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

If you call in it lets say update, it will be considered in the next physics update

[round violet]

i mean the issue isnt that the trigger exit is called delayed, its thats it isnt called at all, so i dont fully understand why flushing the transforms to sync it with the physic engine makes it work, but not doing it never considerate it later on

[soft shard]

If it will happen in the next physics update, wouldnt you want to call it on FixedUpdate?

[plucky inlet]

It was just as an example, that it will not be considered in the current run of the exeuction order anymore when you set it after the physics update has happened, but in the next frame

[soft shard]

Ah, fair enough

[plucky inlet]

As an update to my issue. It seems to depend on the complexity of the assets. When loading two smaller, it works most of the time. loading 3 at a time, it crashes unity immediately, no matter the asset.

Okay, pinned it down to assets including materials.

[frail dust]

Folks I am making a 2D game, I want the gears to move outside the boundary and immediately enter the screen from the left side, and sit on the new positions accordingly, such that it looks like assembly chain. How do I do it?

It shall look like a circular loop

I want to apply it to different rows and columns

So I would want a generalised approach

If its a column, ofc it should move up or down and in a circular loop

[lean sail]

yes it is. it must be an issue with your setup

[round violet]

are you using a RB on you capsule ?

i am using the charatcer controller, this is probably the source of the issue

[lean sail]

i find it a bit confusing what you mean. its gonna be very hard for anyone to help also if no one knows what information you're currently storing like if theres a path you have defined

[frail dust]

Im using a grid tile system to store the gears

[frail dust]

There isnt any path, Basically its a match 4 game. I want that if I swipe in a direction, the whole row/column should move like an assembly line

But in a circular queue manner, the last element comes to the first, and so on

[lean sail]

yes, i dont use the CC so i dont really know how that interacts with other objects

[lean sail]

have you tried coding anything related to this? this sounds more like a #💻┃code-beginner issue to me, where you just need to shift every element in your row or column over by 1 or -1, and then handle the first/last element separately.

[mellow sigil]

You can't change the gameobject position directly with charactercontroller because the CC overrides transform position and it would just snap the player back to the original location. So if you disable the CC before changing the position and then re-enable it, then it would make sense that physics messages don't work while the CC is disabled

[sick cove]

I have a porblem with moving platforms. i'm making a balance game, however when i'm on the moving platforms, i rotate with the platform, but the moment i jump the rotation of the player gets reset to the basic one.

for setting the transform of the player so it follows the platform i use the following on the platform

    private void OnTriggerStay(Collider other)
    {
        other.transform.SetParent(transform);
    }

    private void OnTriggerExit(Collider other)
    {
        other.transform.SetParent(null);

and for the player (without the bar code)

void Update()
{
    isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);

    if(isGrounded && velocity.y < 0 )
    {
        velocity.y = -2f;
    }

    if(balanceRotation  > 0f)
    {
        balanceRotation += lean * Time.deltaTime;
    }
    else
    {
        balanceRotation -= lean * Time.deltaTime;
    }

    balanceRotation = Mathf.Clamp(balanceRotation, balanceMin, blanceMax);
    transform.localRotation = Quaternion.Euler(0f, 0f, balanceRotation);
    balanceSlider.value = balanceRotation;

    if (!isGrounded)
    {
        Controller.Move(move * speed * Time.deltaTime);
    }
        velocity.y += gravity * Time.deltaTime;
        Controller.Move(velocity * Time.deltaTime);
}
    public void Balance(InputAction.CallbackContext context)
    {
        Vector2 vec = context.ReadValue<Vector2>();
        float mouseX = vec.x * mouseSensitivity * Time.deltaTime;
        float mouseY = vec.y * mouseSensitivity * Time.deltaTime;
        balanceRotation += mouseX;
    }

    public void JumpMove(InputAction.CallbackContext context)
    {
        Vector2 vec = context.ReadValue<Vector2>();
        moveX = vec.x;
        moveZ = vec.y;

    }

What's the condition to use invoke() and startcoroutines()?

Why many of my friend say dont use invoke()

[trim schooner]

Invoke is string based, it's slow and error prone

[copper sentinel]

Unity has 3d game kit, which is good resource to learn about 3d movement. Other than that, you can use 3rd party asset to speed up development.
Coding 3d character controller and interaction with moving platform is very advanced topic. If you still don't want to use 3rd party asset, I can give some recommendations:
Code using rigidbody with frozen rotations as based instead.
Don't parent to the platform and use local transform. Instead calculate platform's delta position and delta rotation, then add those value to your character when on platform.

[sick cove]

i'll take a look at this, thank you.

[leaden ice]

Coroutines can do everything Invoke can do and a lot more. It's more flexible and recommended overall.

[knotty sun]

Invoke has only one purpose, to dynamically run a method. If you are hardcoding the name, don't use it

[runic linden]

I am saving level data on firebase because I want to allow my users to create levels. One data item is date created and last download, so levels get deleted after long inactivity.

This line here creates the string: DateTime.Now.ToString("yyyy-MM-dd")
For some reason the data can't always be parsed by this line: DateTime time = DateTime.Parse(dateCreated);
(dateCreated is a string in a Dictionary)

The data generated by my pc is fine and in this format: "10/16/2024 3:03:33 PM"
The data generated by my phone is not working, the parse dies: "16.10.2024 15:31:12"

Why? And how do I solve this?

[knotty sun]

Why, look at the difference. How to solve, supply multiple format strings

[runic linden]

I can see that there is a difference but do I need to provide a format when writing first?

[knotty sun]

yes best to supply a fixed format when writing, also best, because of cultural differences to supply multiple formats for the Parse
or use the InvariantCulture

[shy herald]

So overall, coroutines are better than invoke()?

[runic linden]

But to me it looks like my script crashes when the format is wrong, so how would I loop over all available formats?

[knotty sun]

read the docs, there is an override to supply an array of format strings

[sturdy hinge]

Hey folks, looking at improving efficiency for a scenario I have, and still fairly new to unity so bear with me please.

I've got 6 cameras I'm processing to send out as 6 streams. Right now, each camera renders to a texture, the texture is then converted (YUV) and streamed out. It can be pretty choppy though, and it seems mostly related to the quantity of cameras/render textures in play. If I have one higher resolution camera, it seems to be much more efficient than 4 lower res cameras (same total pixels). Unfortunately I have some resolution constraints, so I was thinking it might be more efficient to have one camera (covering the same area as the 6), render that one texture, then blit to smaller resolution temp render textures. Any thoughts on going down this route?

[knotty sun]

If you have 6 cameras render 1 camera per frame, no one will notice the difference

[sturdy hinge]

Its all up simultaneously, won't work unfortunately.

[leaden ice]

what does "streams out" and "streams" mean exactly in this context?

[sturdy hinge]

network video stream; rtsp.

[sturdy hinge]

Not the part thats slowing things down btw.

[leaden ice]

I mean let me ask you this

if you disable the streaming entirely

and just render the 6 cameras

can your game even handle that part?

rendering 6 times is a lot

[kind shale]

hey, what would be the best method for creating physics based movement, simply to use moveposition, rigidbody.position, mess with velocity? does moveposition even take colliders into account?

[sturdy hinge]

Yes, but thats the issue - it seems really inefficient. I've got a pair of a6000s to support it.

[leaden ice]

What does "best" mean in your opinion? What criteria are you using?

MovePosition does not respect collisions for the moving object, only for objects being moved into.

[sturdy hinge]

Thats why I was thinking one much large cam/rtext, then copy/crop with temp rtexts

[leaden ice]

are they com[pletely different camera views? The same view?

what's the situation

And yeah if you're streaming over network you could certainly limit each one to like 30FPS or something

and alternate which ones you're rendering

[kind shale]

virtual reality, physics based, best way for an object to be set to the irl-controllers position, want the object to be able to collide with other static objects
i'm thinking moveposition would be good but if the object won't be able to collide with any other objects then i'd rather not use that method

[sturdy hinge]

Adjacent views, shown side by side. Limitation on resolution for the receiver on the far end stream means I need multiple streams, or I would just do one big one and be done. ~12k resolution canvas. I'm actually going for 29.97 (which the stream is doing clean, and actually much more lightweight than I had expected, I could have done this in 1gbit but I've got 10gbit, so thats all good). Problem is some scene updates drop the fps down to ~15, which is no bueno. And some other animations (which I'll be looking into separately) drop things down further.

I can't alternate since they are all visible at the same time

[limber sky]

anybody knows why the collider isn't matching the line renderer anymore when rotated, dispite having the same points?https://i.imgur.com/NT4ZmvT.gif

searching it up I only find posts mentioning non-uniform scaling, but all objects have 1,1,1 scaling

[sturdy hinge]

I'm fine with just the renders themselves (sans scene updates or other animations), its around 35-40fps. That said, if I take 4 1080p streams, and use one camera covering the same area at 4k, I get a far better framerate (damn near 60).

[leaden ice]

Set the velocity such that it will reach the VR controller position in one frame

[sturdy hinge]

Which is why I was thinking one large camera, copy/crop to temp r textures

[kind shale]

thanks!

[fringe ridge]

So i'm creating an isometric game and ran into an issue. Basically, The bullets the player shoot have a correct direction vector (follow the red arrow along the ground), but the rotation is not right, they face forwards of the player. Anyone know how to make the rotation follow the direction vector?

[leaden ice]

theObj.transform.forward = direction; or for 2D: theObj.transform.right = direction;

[fringe ridge]

god damn, im stupid. Thanks 😄

I was trying to do math to figure this out, but forgot unity can actually handle this

[leaden ice]

Let the computer do the math 😄

[worldly stirrup]

Greetings, I joined this server for some help with my 2d platformer character controller: It currently can run with acceleration and deceleration, jump with coyote time and jump buffering, and walk on slopes

However, the problem I'm dealing with is jumping while on a slope: When the player walks down or stands still on a slope and jumps, the jump works as intended, but if it tries to jump while walking up a slope, I get a very shallow jump

I'm thinking it's because the vector of the slope and the vector of the player's velocity when the jump occurs are too similarly to each other

Would like help on making it work just like every regular jump

Let me just paste the relevant code

[indigo tree]

Are you using the unity physics system?

[worldly stirrup]

i am using a rigidbody to move it, but I'm not using any other physics related things

I just manipulate the rigidbodies velocity and detect collisions with raycasts

this is the function that detects ground and ceiling collisions

actually let me paste it into a text file

checkVerticalLevel handles ground and ceilings collisions, and also gets the angle of the slope, yMovement is responsible for everything related to manipulating the y value (gravity, jumping and y values on slopes)

[limber sky]

just realized this is because collider 2D only works on xy plane but the grid should either be on xz or angled slightly (like in the picture)

[limber sky]

how can I make this work in a 2.5D game like Darkest Dungeons?

[indigo tree]

Does darkest dungeon even use collision? I thought it was a turn base game

[leaden ice]

darkest dungeon doesn't really use physics at all?

[limber sky]

hmm, no I guess it doesn't since units are always next to eachother so there's no depth to take in mind...

[leaden ice]

I mean it doesn't use physics because... it's an RPG with no physics simulation.

[limber sky]

but the corridors are in 3D space

[leaden ice]

wdym

[limber sky]

the floors and walls are different planes, same as this game, but in Darkest Dungeons you don't have to select UI buttons on the floor

[leaden ice]

what does "ui button on the floor" mean

maybe show screenshots etc of what you are asking about

[limber sky]

sorry about that should've started with that lol

here's my scene currently

each hex cell has a 2D collider which works well... but since they only want to work on XY and the floor plane is angled slightly, the mouse detection isn't a perfect fit

[leaden ice]

use the 3D physics engine

[limber sky]

what's the equivalent of a polygon collider in 3d?

[leaden ice]

MeshCollider

But really

[limber sky]

I'll give it a try

[leaden ice]

why use a collider for this at all

use a Grid

[limber sky]

grid?

[leaden ice]

https://docs.unity3d.com/Manual/class-Grid.html

You can set it to hex mode

I'm currently in a problem that's new input system apply binding override just doesn't work, it literally does nothing do you have to like disable the map or disable the action before you do things?

And get grid coordinates with https://docs.unity3d.com/ScriptReference/GridLayout.WorldToCell.html

[leaden ice]

#🖱️┃input-system show what you tried

[limber sky]

I was looking into that but couldn't figure out how to replace the tiles with my prefabs...

[worthy hatch]

anyone find a solution to the bug where compiler will get stuck on shader variants for 3 days straight?

literally have to close and re-open unity every damn time i make a change to code

[limber sky]

ack and I just remembered I had to avoid mesh colliders because it doesn't take in my array of points like a line renderer

[leaden ice]

Grid doesn't need/imply the use of tiles

it's strictly for handling the coordinate system

[worldly stirrup]

Any help with this?

[worldly stirrup]

I sent a link

[leaden ice]

You're just doing this:
velocity.y = jumpForce;

note that if you're already going up a slope, that implies there's already some upwards velocity

[worldly stirrup]

Yeah, because this is the current code

[leaden ice]

So like... a jump with velocity 5 on a flat surface feels normal, but if you're already going up at 3 m/s and you change that to 5m/s, it won't feel like much

[worldly stirrup]

I'm resetting the y velocity before setting it to jump Force

[limber sky]

ah so then what you mean to do is instead of using a collider, I could just convert the mouse position to figure out which cell is pressed/hovered on?

[leaden ice]

So what?

You're going from 3 to 5, for example

that's only a difference of 2

It would be better if you didn't reset the velocity

and added it

[worldly stirrup]

Let me try that

[leaden ice]

velocity.y += jumpForce

also jumpForce is a poor name for that variable

since it indicates a velocity, not a force.

(though it becomes more appropriate if you're doing it additively)

[worldly stirrup]

I know, but for the purposes of this, it acts like a force

[leaden ice]

only if you make it additive

[worldly stirrup]

So, I changed it

The player jumps correctly, but it feels kinda inconsistent

[leaden ice]

there's not enough context here to know why really

sharing the full script would be better

[worldly stirrup]

When you're going down a slope, y velocity is already negative, so the jump is way smaller than the jump when you're climbing it

[leaden ice]

which makes sense, physically

but if you want that to change

you have full control over the code

and access to if statements

so you can change it however you please.

How to make inertia camera like in minecraft in optifine mod?

[leaden ice]

no idea what that is, but options include:

• Use Cinemachine with damping
• Write the code yourself

Hello People. I am new to Unity and as a 17 year old I have 0 knowledge about Game Development but I did some research and ended up downloading Unity so as a beginner I am here for some guidance if someone can share some tips it will be really appreciated.

[upper pilot]

I am creating elements in the same frame and this was the only way I found working, but I have added 2nd element that seems to not be calculated the same way and it no longer works.

[worthy hatch]

Here's a tip, prepare yourself for pain. My workflow for the past 3 months has been, make changes to code, press play, wait for Compilation of Shader Variants for 30 minutes, finally test changes

[worldly gulch]

Understood thank you for the tip. I'll note it down.

I wanna make a train move but with throttle control

Can someone

Guide me

[drifting pelican]

Brah

[tired meteor]

I'm new

[drifting pelican]

Um I never do a these things, but try just to calculations variable add another variable value of throttle, and this variable should be from 0 to 1, and the impulse just multiplies by this value

[tired meteor]

Il try it

[hybrid relic]

watch some unity tutorials before you ask such stuff

that is not easily explained and will need good understanding of multiple things

the first you need your train to follow a track (ofc after you learn the basics of unity dev itself), this is fairly easy since you can just follow a spline

then you need to control the speed via a throttle, this is even more easy as you could just modify the speed value of the train moving along the spline

step by step

also this would belong into the beginner channel anyways, this is beginner stuff

[hybrid relic]

never seen so much "technical" words used so wrong
Also if you never done these things how do you make games, most of it is basic gamedev

[drifting pelican]

Like a

float impulse = (a + b / c) * throttle;
trform.position = somethingForRails * impulse;

[drifting pelican]

Also sorry for that I have bad skills of explanation

[lean sail]

As they wrote in the other channel, if you dont know how to help (or even come close to solving the issue) then you dont need to help.

Hi, I am making an android game and I want it to have a large number of levels. Currently I have created a system where I can create levels in Play Mode and then they get saved, in my Streaming Assets folder. But when I open the game on Android I can't access them due to some android bs that forces me to use UnityWebRequest. For the last 3 days I have been trying to make it work but I just can't. I have tried several ways to do it, every one of them has failed only on the android side. Is there an easy different way to save levels other than saving the data on files?

[knotty sun]

Application.streamingAssetsPath is read only (via webrequest) on Android. Use Application.persistentDataPath

[drifting pelican]

I don't send anything anywhere, regarding the train, I answered in my own words as I know, since I've never done the mechanics of train movement before, and regarding Json, I just asked the gpt chat to write an example of how it would look, and I sent it to the chat to see how correctly it was written, purely out of interest, since I don't plan to make a mod system for my game now

[hasty plinth]

I want the data that I have generated in Unity in play mode, to be what the android version reads to re create the stages. I have managed to generate them and then use them in Unity, but when I try to do this on android with the same files, get
request.result == UnityWebRequest.Result.Success this returns false

[knotty sun]

so what url are you using? are you using the file:/// protocol ?

[hasty plinth]

here is my code

public async static void LoadStageDataAsync(int StageNumber, StageManager stageManager)
    {
        string path = Application.streamingAssetsPath + "/stage" + StageNumber.ToString() + ".data";
        byte[] fileData = await LoadFileAsync(path, stageManager);
        BinaryFormatter bf = new BinaryFormatter();
        using MemoryStream memoryStream = new MemoryStream(fileData);
        StageData stageData = bf.Deserialize(memoryStream) as StageData;
        stageManager.DebugLog(stageData.StageNumber.ToString());
        stageManager.data = stageData;
}

async static Task<byte[]> LoadFileAsync(string file, StageManager stageManager)
    {
        string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, file);
        UnityWebRequest request = UnityWebRequest.Get(filePath);

        await request.SendWebRequest();

        if (request.result != UnityWebRequest.Result.Success)
        {
            stageManager.DebugLog("Failed to load file");
        }

        return request.downloadHandler.data;
    }

[knotty sun]

so you are using no protocol at all

[hasty plinth]

If you say so, then thats right

I don't understand the logic behind this code

[knotty sun]

also you are putting streamingAssetsPath in there twice

a simple debug.log would have shown you this

[hasty plinth]

The problem is that this code works on Unity but does not on Android

So thats not the only issue I believe

[knotty sun]

nah

anyway you need the file protocol for webrequest

enough, unless you get muted as well

[hybrid relic]

Fair

[hasty plinth]

as I said I don't understand any of the mechanisms on a deeper level, so if you want to explain something to me you are going to have to be more specific

But I want to emphasise again my main question for a moment

I asked if there was an different way to this, to avoid all of this which I dont understand

[knotty sun]

well you could use Resources.Load to load data but you cannot save there. you can only save to persistentDataPath

anyway you know what a url is, right?

[hybrid relic]

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

[hasty plinth]

Currently I don't plan to be able to create stages on the built version. I only want to have a way to create stages when in play mode in unity because it is easier to do it that way because I han drag and drop gameobjects in the scene without creatin systems of my own

So that might be a route that I can follow

[knotty sun]

then you can save to Application.dataPath + "Resources" and load using Resources.Load

[hybrid relic]

wait i completly missed that

thats not what a UnityWebRequest is for apparently it is, ok i guess im dumb

sorry

[knotty sun]

it is if you want to read from streamingAssetsPath on Android

[hybrid relic]

what in gods name ?!? ok then, thanks for the knowledge Steve
I dont know about Android, i missed that part with Android, i thought he wanted to access a API from the code

[hasty plinth]

Just to defend myself a little. I have been using unity for about 3-4 years now, so I am not that new to this. I understand how to use unity to create simple games. Now on the other hand I have no prior experience with c#, thats is why this bit, that is very c# heavy I can't understand.
(Just to clarify I am not saying that you are wrong, its just that this is quite far from my comfort zone as a game dev)

i will save the videos and watch them when I have the time

[knotty sun]

to come back to my question, do you know what a url is?

[hasty plinth]

I think so

[knotty sun]

so you know they usually begin with http:// or https://, right?

[hasty plinth]

will I be able to use Resources.Load on android?

[hasty plinth]

yep

[knotty sun]

yes

[hasty plinth]

without doing all this mumbo jumbo I am currently doing?

[knotty sun]

so, those are protocols. if you want to read a local file (like from streamingAssetsPath on Android) you need to use the file protocol which is file:///
note three / not 2

[knotty sun]

yes, go and read the Resources.Load docs

[hasty plinth]

"file" is the file name, or is it just "file" to specify its a file?

[knotty sun]

file is file like http is http

[hasty plinth]

alright

[knotty sun]

anyway, I'm done, I feel like I'm wasting my time here

[hasty plinth]

No problem

Thanks for trying to help

I really do

And I think that Resources.Load might have been what I had been searching for from the beggining

If it works I will let you know

(if it doesn't I won't bother you, don't worry)

[pure ore]

Got a question. Is it necessary to make a script for the new inputsystem that makes floats or bools like Run() so you don't have to call the ReadValue method every time?

[cold parrot]

You can subscribe the events it provides on each action but you need to get the value somehow, so not sure what you’re asking?

[pure ore]

I was gonna make a class that basically does

public bool Run() => PlayerInputActions.Player.Sprint.ReadValue<float>() > 0f;
``` So that I don't have to call ReadValue every time I want to use a input. I can just put all of them in that class and call the floats and bools

[cosmic rain]

Sure, you can do whatever you want.

[pure ore]

tbh, I just got into Unreal and it seems easier than Unity

[leaden ice]

Do you think the code police will stop you?

[dusk apex]

Maybe it's a c# vs blueprints things instead for you tbh

[cosmic rain]

You are free to use whatever engine you think is suitable for you and your project.🤷‍♂️

[pure ore]

I mean, I have people every time I come here and ask a question "Oh, this would be better to do it this way" so I think I am being forced to use certain code

[cosmic rain]

Don't listen to them, unless they provide a reasonable explanation that you understand and agree with.

[dusk apex]

If you ask to be critiqued, you'll get it.

[pure ore]

No, I didn't ask to be critiqued

[pure ore]

I want to use Unity, but about a few years ago I fucked up my morality on code. I decided to "read" some code from another game, like the entire codebase, and it fucked me up from figuring out my own solutions. Now, say whenever I want to make an UI Manager for my game, I think of the ui manager code of that game and I can't use that so it's like a cycle now

I know its not right to decompile code, and I never did it again, but now its like... I can't even use Unity now because every time I try to code something similar to the code in that other game, I end up unintentionally coding it that way

[dusk apex]

I don't think folks care about that - other than the server rules prohibiting decompilation and the usual ai generated code issues. They'll probably not be interested in helping you fix/adjust code you're not aware of though.

[pure ore]

Yeah no I'm not asking for help with decompiled code, I'm just explaining my mind is fucked up now on that front

[cosmic rain]

Then read more code. Of different projects. See how other people implement similar features. Just having read one way of implementing is not gonna teach you much.

[naive swallow]

If it's a problem to use that code - don't use it
If it's not a problem - just use it

[cosmic rain]

Also, consider a chair. You can use it many ways. You can stand upright on it, you can do a handstand on it, you can sit backwards, you can lie down on it in different orientations. You can put the chair upside down and sit on it like that. But the most convenient way is to sit on it normally.
You can consider this being forced to use the chair in a certain way, but it's better to think that the chair was designed in such a way that there is a certain good way of using it.
The same with code. Although, code gives you a lot more freedom, there are better and worse ways of using it in certain scenarios, that many people before you discovered and documented. You can sit on your chair however you want, but it's always good to have an idea of what's the commonly acceptable way.

And you don't have to follow an example of that one guy you've seen balancing on the upside down chair standing on one leg.

[cold parrot]

Also you are making up your own problems to match his solution, if you identify your own particular problems to solve, that known solution may reveal it’s shortcomings

[pure ore]

What are you referring to? The learning the other game's code?

[pure grove]

hello after learned about unity's new input system, I converted my game's input to new one however that one seems much faster (kinda instant) on axis detection when old one was much more slower. how can I make it like older?

like it was going from 0 to 1 not instantly but now it is

[leaden ice]

sounds like you were using GetAxis before

GetAxis has acceleration built in

GetAxisRaw does not

[pure grove]

horizontalAxis = Input.GetAxis("Horizontal"); I was using that yes

[leaden ice]

You can achieve this same behavior easily with e.g. Mathf.MoveTowards in Update

[pure grove]

inputActions.BallGamePlayer1.MovementHorizontal.performed += ctx => moveInput = ctx.ReadValue<Vector2>(); now Im just using that

[leaden ice]

Vector2 currentInput;
Vector2 targetInput;

inputActions.BallGamePlayer1.MovementHorizontal.performed += ctx => targetInput = ctx.ReadValue<Vector2>();

void Update() {
  currentInput = Vector2.MoveTowards(currentInput, targetInput, acceleration * Time.deltaTime);
}```
Psuedocode example^

[pure grove]

what is the exact number of acceleration though 😄

game needs to feel same

[leaden ice]

whatever you have "gravity" set to in the input manager for that axis

[pure grove]

it was default okay let me check ty

is it better to have different action maps for different local players? or should I just put them as seperate actions

[leaden ice]

no

unless they control differently

they should all use the same map

the PlayerInputManager/PlayerInput combo will automatically assign different devices to each player, based on your control schemes.

[pure grove]

BallGamePlayer1

so this is wrong

I should just have BallGamePlayer?

[leaden ice]

yes

[pure grove]

okay but how about if I want allow controllers sure but also allow secondary player on same keyboard?

[leaden ice]

Here's a thread detailing how to handle the keyboard https://discussions.unity.com/t/multiple-players-on-keyboard-new-input-system/754028

[soft shard]

It might help to look up code patterns in C#, I find when I have a problem, the solution tends to be breaking it down into small steps, and seeing which pattern can best help resolve those steps, then your not relying on others exact way of coding to make progress in your game, though if its well-written code, its likely using some kind of patterns anyway - I would suggest making a second blank project just to practice using some patterns and familiarize yourself with a workflow, you can consider it like a "sandbox" for coding

[formal wagon]

Hey all, anyone know how I'd be able to apply a shader on top of a UI I've made with UI toolkit? Want to be able to use this to get some fancy effects work done, but I'm not sure how I'd go about getting that working with my UI

[crimson trellis]

Quick question if I use generate C sharp script option for input system and I change a binding at runtime will The binding be changed for the generated c# class?

Bruh the input action assets there's a binding that is literally set to None and somehow the c# generated script is still using the old binding

[soft shard]

Is there a way to force a material or a SkinnedMeshRenderer to update? Im changing the materials _BaseColor on a HDRP lit material (using a Transparent surface type), the inspector shows the values are updated, I can see the color values change to expected values when clicking the color property, but the mesh itself is not updated in the Game or Scene window, unless I make literally any change on the materials inspector, im guessing some kind of forced update need to be made but I cant seem to find it in the API - for context, I am trying to make the materials of 1 specific model fade out over time, "rend" is an array of skinned mesh renderers on said model:

for (int i = 0; i < rend.Length; i++) { SetMats(rend[i].materials); }

void SetMats(Material[] mats)
{
for (int i = 0; i < mats.Length; i++) { mats[i].SetColor("_BaseColor", Color.Lerp(mats[i].color, Color.clear, t / fadeRate)); }
}

What I could find online suggests it may be an editor glitch but it also doesnt visually change in a build

[mossy snow]

try assigning the material array back to each renderer

[knotty sun]

is this being called from a Coroutine?

[soft shard]

Nope, its not being called by a coroutine, just Update, ill try re-assigning and see if that helps

[knotty sun]

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

[soft shard]

Interesting, re-assigned almost worked (unless im doing it wrong?) now the material just fades to black instead of taking the alpha as well, the color shows the alpha is zero, and the surface type is Transparent, the logs also give the expected value of 0, is something incorrect here? (from the screenshot, if I make a change to any value in the inspector, it will then be invisible correctly)

for (int i = 0; i < rend.Length; i++) { var m = rend[i].materials; SetMats(m); rend[i].materials = m; Debug.Log(m[0].color + " | " + rend[i].materials[0].color); }

void SetMats(Material[] mats)
        {
            for (int i = 0; i < mats.Length; i++) { mats[i].SetFloat("_SurfaceType", 1f); mats[i].SetColor("_BaseColor", Color.clear); }
        }

[knotty sun]

Color.clear is transparent black so if you are seeing black then the transparency is not active

https://discussions.unity.com/t/how-to-color-transparent-area/1483271

[worldly stirrup]

Is it okay if I ask for help about the same issue I asked yesterday?

Because I still don't have any progress on fixing my problem about jumping on slopes

[thin aurora]

You can bump your question, over a day ago is plenty of time

It's not a problem, but people usually bump when their question of away from view and that's not okay

[soft shard]

Thats odd, I thought Surface Type Transparent allowed for transparency to be active, why does it then apply correctly after making any change at all to the inspector for that material? Even something unrelated like toggling "Receive fog" for example? Or changing the sorting priority, or even adjusting the color (which then is forced back to transparent black since the code runs in Update, but that forces the material to also update and become invisible correctly) - if the alpha was somehow not active, this should be true regardless of what I change right?

[worldly stirrup]

Alright, so, to reiterate: I'm making a custom character controller for a 2d platformer, so far I have functional running, jumping with coyote time and jump buffering, and movement on slopes. However, I'm having an issue with how jumping is handled while on a slope. I want it to function like how it functions in Mario 3: Having the same jump height, regardless of the terrain. While it works when descending down a slope or standing still on a slope, when I climb the slope and press jump, the jump height is really small.

[knotty sun]

This does seem to be more of a shader issue so you might be better asking in #archived-shaders. Unfortunately I don't know the HDRP shaders well enough to help you

[worldly stirrup]

My code currently only sets the y velocity to the jumpVelocity.

[soft shard]

Alright ill try that channel next, thanks for the insight so far!

[thick terrace]

i don't know the HDRP lit shader but that sounds like you might need to set some shader keywords, which the inspector might be doing for you when you change stuff there

[worldly stirrup]

I was told to increment the y velocity by the jump height instead of setting it, but that causes inconsistent jump heights.

https://hastebin.skyra.pw/kuveqogege.pgsql here are the functions for handling horizontal and vertical movement respectively

[soft shard]

Hmm, maybe, nothing I can see from the Lit shaders exposed keywords that could indicate it, but that may be a good point

[worldly stirrup]

Some explanations about variables: colls.levelAngle is the angle of the slope, angleRad is colls.levelAngle multiplied by Mathf2.Deg2Rad

[cursive granite]

Hello I have 2 scripts, that check how many correct/wrong buttons I have pressed. If I get a wrong combination, the Disappointment Counter should be incremented by 1, but currently it does so by 2 or 3. My guess is that happens because it stays too long in the Update function, but I don't know how to fix that.

    void Update()
    {
        if(amountright == 8)
        {
            SDR.RotateDoor();
        }

        if(amountright + amountwrong == 8 && amountright <= 7)
        {
            resetnow = true;
            DisappointmentCounter++;
            if(allowreset)
            {
                fullreset();
            }
        }
    }

    private void fullreset()
    {
        if(resetnow)
        {
            amountright = 0;
            amountwrong = 0;
            resetnow = false;
            allowreset = false;
        }
    }```

```cs
void Update()
    {
        if(GBC.resetnow == true)
        {
            resetbutton();
        }
    }

    protected override void Interact()
    {
        isPressed = !isPressed;
        GetComponent<Animator>().SetBool("Pressed", isPressed);

        if(isPressed == true)
        {
            GBC.amountwrong++;
        }
        else
        {
            GBC.amountwrong = GBC.amountwrong-1;
        }
    }

    private void resetbutton()
    {
        Debug.Log("Called resetbutton wrong");
        isPressed = false;
        GetComponent<Animator>().SetBool("Pressed", isPressed);
        GBC.allowreset = true;
    }```

I left out the variable declarations, as those function as intended and would make the message too long for discord

[knotty sun]

I think you will find that the Interact method is being called more often than you expect. I see nothing wrong with your other script

[cursive granite]

but the interact function has no impact on the Disappointment Counter, has it?

because that just plays the animation and sets the amountwrong

[knotty sun]

it increments the values which your other script is depending on does it not

[worldly stirrup]

Anyone?

[cursive granite]

Yes, but even if it would increment amountwrong by more than it should, it should just reset sooner.
But just to be sure I checked with Debug.Log and the interact function only gets called once per interaction

[subtle path]

does unity have problems saving the Sprite Component to json? because i get a very long error msg when trying to save a simple data container

    [System.Serializable]
    public class ShopItem
    {
        public Sprite Image;
        public int Price;
        public bool IsPurchased = false;
    } ```

i dont really know what to do

[grizzled tiger]

Put the sprite in resources and save the file path instead, or create a scriptable object and assign a unique id it can reference at runtime from a sprite database manager component thingy.

[subtle path]

ok ill try

[cosmic rain]

How are you serializing it?

Newtonsoft? Yeah, that wouldn't work.

[subtle path]

😦

[cosmic rain]

Imagine you give a detailed building plan of your home and a 3 hour lecture about it, whenever someone asks you for your address. That's basically what you're trying to do.

[subtle path]

i.. dont really get that metaphor... but... yeah i guess its more complicated

[cosmic rain]

Sprite is a very complex object with a lot of references, possibly recursive/looping ones too

Some even point to the GPU.

If you were to save the whole sprite object and it's dependencies, it would basically be the same as copying a huge chunk of the application memory and saving it to disk. Meaningless and crazy at the same time.

This wouldn't be a problem if you were to use JsonUtility, as it would only serialize what is actually serializable.

[subtle path]

but i had already lots of problems with jsonutility so i switched to newtonsoft lol

[knotty sun]

The reason is right there in the error message. Nothing to do with Sprite, It's the normalized property of Vector3 because it refers back to it's enclosing struct

[leaden ice]

What you actually want to do is save an identifier that you can use to look the sprite up

Not the sprite itself

Your choice of serializer is kind of beside the point

Use addressables or resources.load

And save only an identifier to use with that

[subtle path]

will do, thanks

Im working on an isometric game, where 3d characters move along a rotated ground (red arrow). everything works fine, except when collisions occur, the objects often can be sent flying away from the ground, not along the ground. I was thinking of just modifying the position directly (making the characters be children of the ground and then setting their z localposition to 0) but that seems like a back handed approach. Any suggestions?

[dire crown]

So found a quirky issue

I assign a mesh into a MeshCollider.SharedMesh and next line checking I get that the shared mesh is null

_meshCollider.sharedMesh = meshResult.mesh;
if(_meshCollider.sharedMesh == null){
    Debug.Log(meshResult.mesh);
}

I cannot find a way to consistently replicate it, but here i get a log that the mesh is not null so I dont get how shared mesh can be null

[cosmic rain]

Which is a part of the Sprite object and wouldn't be serialized with JsonUtility.
The point is, while Newtonsoft is more powerful, it also brings a lot of nuances. As they say, great power requires more responsibility or something like that.
While JsonUtility would prevent you from doing unreasonable things.

[cosmic rain]

I'd assume that it happens the first time you assign it. Physics would need to bake the mesh into a compatible object(especially if it's a convex collider), which might take a frame or 2. Pure speculation though.

[knotty sun]

tbf JsonUtiiliy just about prevents you from doing anything

[dire crown]

I bake the colliders beforehand through a job. but i found the bug because after many frames I was seeing no mesh attached to it. Aka it stays null forever

[dire crown]

im so confused , i dont get it

[dire crown]

it seems that i need to enable the mesh collider before assigning the shared mesh or sometimes it fails

Hi

I want to write a new message to a file that's in github

And tbh I don't know if it's even possible or not

I'd be glad if someone helped me

[mellow sigil]

It's not possible without convoluted setups. What do you need it for?

[maiden ibex]

I want to build my game for web and write some stuff about players there so I can read it later

To observe

Is it too crazy and useless idea? Idk maybe not sure tbf

I just want to see how players are playing my game

[mellow sigil]

It's not crazy, it's called analytics and many games have it but Github is not suitable for it

[maiden ibex]

What then?

Google cloud?

[mellow sigil]

Look up Unity Analytics for example

[maiden ibex]

Huh

Okay

Oh boy they thought of everything

This is neat

Thanks man @mellow sigil

[dusky lake]

Yes, on the rect transform use the fill screen option and then tick "keep aspect ratio" on the image

That should solve it but it has not further settings like limiting the size i think, you'd have to limit the size of the parent for that

[thin aurora]

This is a coding channel for coding questions

[dusky lake]

#📲┃ui-ux

Make the RectTransform fill the whole height - not the whole width (make the width fix), then it should scale with height instead of width

[distant galleon]

Hi

[plucky lance]

Do you need to use navmesh for pathfinding in 3d?

[knotty sun]

need, no. there are other options. If you want to use the Unity package then yes

[plucky lance]

What exactly is navmash?

[knotty sun]

why don't youi go and read the docs and find out

[plucky lance]

True lol

[teal raven]

why do we write List<ClassName>() waypoint = new List<ClassName>(); in unity
While I wrote the code like this: List<ClassName>() waypoint; and it still works fine for me.
When I use the data in it and also it is [SerializeField]

[thin aurora]

Don't cross post #💻┃code-beginner

[naive swallow]

If a collection is serialized, when the inspector is rendered for an object, it will initialize the collection to empty to be drawn in the inspector. If it is not serialized, you need to create the collection or it will be null, and will give you an error when you try to use it.

[leaden ice]

new creates a new list. This is necessary if it's not already somehow created.

[vague cosmos]

Currently, i'm trying to make a throwing knife projectile that is made of two colliders, that deal different damage depending on what part hits. I also have a script on set point between the two parts to spin the knife. My current issue is getting the knife to stop spinning when it hits something. I know the best way to do so is to use on trigger enter, but i dont want the spin point to have collision around the knife object. Is there anyway to do want i'm trying to do? Im attempting a trigger, but it doesnt seem to work

[latent latch]

What's the set up? Kinematic or rigidbody? And how does this forward velocity work with the spinning.

[vague cosmos]

One moment, ill pull that up real quick

[latent latch]

I would go about this making the knife fully kinematic/character controller and drive the forward velocity then use secondary velocity for the spinning (locally)

[vague cosmos]

Currently, the knife prefab is comprised of the blade object, the handle object, and the spin point all with dynamic rigid bodies. The rotation is performed by rb.rotation += 25.0f; where rb is the rigid body of the spin point

[latent latch]

If you want to use rigidbodies then it's only the forward velocity that should be forced while the spinning you could make a trigger collider which stops the rotation.

[vague cosmos]

Yeah, if I have a trigger surrounding the knife would that trigger work for oncollisionenter? Or do need to add triggers around all the other objects?

[latent latch]

You can actually get collision points and use a single collider if you want to do it that way, otherwise composing an object of multiple colliders is how I would probably do it

[vague cosmos]

Yeah, alright that makes sense. I’ve got an idea now, so thanks!

[latent latch]

It's just if you do have multiple colliders then it creates some complications if those child colliders aren't kinematic

but I'm not too sure how you want to control that knife on impact but I assume they should stop colliding and stick into that object

[vague cosmos]

That's the end goal, but at the moment im just letting it fall

One problem at a time

[wintry gust]

Does OnDestroy get called on application quit? I know there is an OnApplicationQuit method already, but are both called in that situation?

[rigid island]

[wintry gust]

I know it does in editor but it's hard to tell in a build because.. well the application is already ended xD

I don't have anything to go off

[rigid island]

You can make dev build and put logs

then check player-log file

[wintry gust]

Ahh, where can I find those logs?

[rigid island]

!logs

honestly no clue what to do here my inventory UI bugs out like that when i drop/pickup shit i gave up a bit ago and came back to it and ive still go no idea

https://pastecode.io/s/s24paas7

id love to bro but i want to fix this shit

Why in 1 script .AddComponent works, but in other it says that .AddComponent doesn't exist?
Both scripts are MonoBehaviours.
https://i.gyazo.com/f7c26ec5a31bae40774dfddea4ffe67e.png

I just copied this script to another and it wont work, "quick fix" only creates AddComponent method

[simple egret]

AddComponent is only available on GameObject if I remember correctly

[upper pilot]

I am hovering over both scripts to see if they are different type, but it's the same

It does work on SkeletonGraphic, I've been using it for over a month in that script, I am adding canvas so I can sort it

using Unity.VisualScripting;

This fixed it

VS "quick fix" didn't mention it, I just look at all "using" statements, copy pasted them and eventually found the one I needed.

It's a bit weird tho, VisualScripting?

[simple egret]

Hover the mouse over GetComponent, see where it comes from.

[upper pilot]

Component.GetComponent

[simple egret]

Might be an extension method, or adding the using directive changed the meaning of SkeletonGraphic entirely

Now do the same with AddComponent

[upper pilot]

https://i.gyazo.com/d120b787563861a602a304da4db34387.png

it is an extension I think, what does that imply?

[simple egret]

The method isn't declared in Object here, it's in some static class you added in scope by including the using directive. Ctrl+clicking it should take you to where it's declared

[upper pilot]

Basically this is the only method I found of creating spine file at runtime based on their forum search:

        SkeletonGraphic skeletonGraphic = SkeletonGraphic.NewSkeletonGraphicGameObject(skeletonDataAsset, transform, SpineMaterial);

Which means I can't use a prefab to create spine file at runtime

"ComponentHolderProtocol"

Thats the AddComponent

[marble dome]

do you know any good tutorials for this? I'm not trying to do it for weapons, i want it to hold a flashlight or similar items dpeending on the target.

I saw few tutorials but I'm really confused on where to start tbh

[rigid island]

have you looked into the animation rigging package ? they have a decent series on it

[simple egret]

So there's a static class ComponentHolderProtocol within Unity.VisualScripting that declares a public static T AddComponent<T>(this Object o)?

[upper pilot]

public static T AddComponent<T>(this UnityObject uo) where T : Component
{
    if (uo is GameObject)
    {
        return ((GameObject)uo).AddComponent<T>();
    }
    else if (uo is Component)
    {
        return ((Component)uo).gameObject.AddComponent<T>();
    }
    else
    {
        throw new NotSupportedException();
    }
}

[simple egret]

Yup that's why adding the using directive brought it in scope

[upper pilot]

but VS wasn't aware of that?

quickfix didn't bring it up, I guess it was added as I was typing before, or maybe i added using manually, I can't remember atm.

[simple egret]

The option for extension methods is usually further down the completion list, if using an older IDE stuff from unimported namespaces won't show for performance reasons

[upper pilot]

I see, that solved it at least, thanks!

public struct GalleryThumbnailData
{
    public string SpineName;
    public string SpineAnimation;
    public string ThumbnailName;
}

Is there a shortcut to create a struct data?(For testing, as the actual data will be read from a file)

        dataList.Add(
            new List<GalleryThumbnailData>{name:name?}
            new List<GalleryThumbnailData>
            new List<GalleryThumbnailData>
            new List<GalleryThumbnailData>
            );

I thought that there was a way to do that inline, but I can't find it, maybe it wasn't for structs hmm

[rigid island]

dataList.Add(new() );
