All TMPro components derive from MonoBehaviour

why do you want it to be a MonoBehaviour though

[raven cove]

Maybe I'm misunerstanding I appologise I am a noob. I just want to read what buttons are being pressed in the\ input field on another script that is all.

[leaden ice]

how would this MonoBehaviour question help with that? 🤔

[raven cove]

Because I could access the variables on that script?

[leaden ice]

you can access variables on any script

any component

regardless of whether it's a MonoBehaviour

[raven cove]

I added public variables on the TMP_Inputfield and I couldn't find them

[leaden ice]

what do you mean by that

how do you add variables on TMP_Inputfield?

Are you trying to modify Unity's built in classes?

[leaden ice]

TMP_InputField uses a custom inspector

so you'd have to also modify the custom inspector

but really

you are definitely going about this the wrong way

there is no need to modify the input field code

[raven cove]

okay I appologise I guess I am too in over my head

[leaden ice]

InputField has events for when things are typed into it. You can just subscribe to those events

[raven cove]

Is that the "OnValueChanged" event?

Okay I think I see now

[shell scarab]

public class WeightedList<T, W> where W : IComparable, ICollection
```How do i implement `ICollection` and not have it apply to W? I tried:
```cs
public class WeightedList<T, W> : IComparable, ICollection, where W : IComparable
```but the compiler doesn't like that.

[somber nacelle]

remove that last comma on the second line.
it is public class WeightedList<T, W> : IComparable, ICollection where W : <whatever constraints>

[shell scarab]

oh, thanks

[daring cove]

Hey,
Im getting this error when trying to build an asset bundle
No AssetBundle has been set for this build.

public class CreateAssetBundles : MonoBehaviour
{
    [MenuItem("Assets/Build AssetBundles")]
    static void BuildAllAssetBundles()
    {
        string assetBundleDirectory = "Assets/AssetBundles";
        
        if(!Directory.Exists(assetBundleDirectory))
        {
            Directory.CreateDirectory(assetBundleDirectory);
        }
        
        BuildPipeline.BuildAssetBundles(assetBundleDirectory, BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows);
    }
}

[rain minnow]

did you create a new asset bundle for the selected object(s)?

[leaden ice]

Not an answer to your question unfortunately but the if statement around CreateDirectory isn't necessary. CreateDirectory will always do the right thing

[ionic socket]

async/await question. I have SelectionManager class that I invoke which includes a Task that I then await in my code. I want to be able to pass in a method through the constructor that I can call and await before setting the result on the Task. I can pass in a method as a System.Action<T> just fine, but that can't then be awaited. Anyways, the question boils down to, how can I pass a method as an argument that can be awaited?

[cobalt gyro]

        {
            checkmark = transform.GetChild(0).transform.GetChild(0).transform.GetChild(0);
            checkmarkToggle = checkmark.GetComponent<Toggle>();

            descriptionTextTransform = GameObject.Find("Weapon Display Info").transform.GetChild(0);
            descriptionText = descriptionTextTransform.GetComponent<TextMeshProUGUI>();  
        }``` I hate myself

Is there a better way of doing this

[ashen yoke]

when you sub a method of a struct that is a member of a class to an event, what exactly is happening?

[swift falcon]

just reference them directly, why do you need GetChild

[cobalt gyro]

I cant apply the instance in the inspector because im going to have these as a prefab

[ionic socket]

GetComponentInChildren<Toggle>() will always return the first result, I believe Depth-First. so checkmarkToggle = GetComponentInChildren<Toggle>(); You can also use [SerializeField] to make variables to hold those references and link them up in the inspector.

[ionic socket]

You can set the linkages within the prefab; use [SerializeField] (or make them public) to view them, and when you're editing the prefab, just link em up, and it'll be maintained for each instance.

[cobalt gyro]

I was thinking about external references in the editor

[ionic socket]

for the toggle, that's internal

description text, you can simply use Find(<magic string>).GetComponentInChildren<TextMeshProUGUI>() and based on how you have it here, it'll always grab the correct one.

[ashen yoke]

yes, you can create a component that flags your Toggle

and then just GetComponentInChildren

or, if its a prefab, make root component that stores references for prefab internals

[ionic socket]

what I would typically do is have WeaponDisplayInfo be a class, which has it's own variables that stash the descriptionText and do a FindObjectByType<> rather than Find.

[ashen yoke]

have

    public struct ValueRef<T> : IDisposable
    {
       public event Action<T> onValueChanged;

its a member of a class

private ValueRef<bool> _ref;

in init

void Start()
{
    _ref = new ValueRef<bool>();
    _ref.onValueChanged += Method();
}

result - subscription happens, then .. unhappens.
delegate is null after some point, i cant track it down even with debugger atm
as soon as struct is changed to class, delegate stops losing reference
what exactly is going on here?

[pine perch]

hi, if i instanced an animation clip, how can i save it with code so it would work even on the build version of the game

[ashen yoke]

removed IDisposable just in case, same thing

any ideas are welcome, its either a bug in clr or i dont understand something

[rain minnow]

I would place the Weapon Display Info GameObject as a reference on a variable in another script, like a singleton, then access the singleton to get its reference . . .

[cobalt gyro]

im only going to need 1 reference so that wont be necessary

[simple edge]

http://kosiara87.blogspot.com/2011/11/cnever-place-event-inside-struct-c.html?m=1
It seems this post ran into the same issue when placing an event in a struct.
They provide a couple of theories why this occurs

[lean sail]

maybe due to how structs are copied, is it creating a new struct at some point

ah that link suggests the same

[ashen yoke]

i understand that something there is somehow related to copy semantics but the struct is a member of a class, accessed and written into as a member shouldnt that avoid unnecessary copies? Also this theory would suggest that structs are immutable which they arent, and that any assignment to any field copies, and ref keyword on structs is pointless

[olive silo]

how can i add "roll" to my camera? or more generally, how can i rotate a transform about the axis that it's pointing in?

i know i'd need to do some quaternion stuff, but i suckk at quaternions.

[ashen yoke]

just create a camera rig from chain of transforms

one rolls, one yaws one pitches

one for distance

one for vertical offset

and the root at the character feet

oh and one for camera mount point, so that it snaps to its position/rotation instead of direct parenting

[olive silo]

i'd really prefer to do it the quaternion way 😅

[ashen yoke]

ah forgot about springs

[olive silo]

in my head it makes a lot more sense to just picture it as a look-at camera with a rotation about its forward vector, and i'd like my code to reflect that.

i already use Transform.LookAt() to look at my player's transform, now i'd just like to add rotation about the camera's forward vector.

[latent latch]

Do you mean to revolve a camera around a point?

[mellow sigil]

transform.Rotate(transform.forward, amountToRotate);

[olive silo]

🤯

[latent latch]

    public static Vector3 RotatePointAroundPivot(Vector3 point, Vector3 pivot, Vector3 angles)
    {
        return Quaternion.Euler(angles) * (point - pivot) + pivot;
    }

[olive silo]

thank you

[latent latch]

this is pasted everywhere

but that with lookat

[olive silo]

this only did what i expected after setting the space to Space.World. why is that? i thought rotation spaces generally only matter in hierarchies.

[lean raptor]

Yo anyone that knows scriptableobjects well, i have an issue where when I close unity and reopen it, my scriptableobject references all disappear, here's the script: https://pastebin.com/P6J9FC3F
(yes there are a lot of redundant ScriptableField attributes, was trying to see if that fixed it, it didn't. I also had my objects originally instantiate themselves directly in the declaration, like public List<QuantumPrefabLink> RealmQuantumLinks; = new List<QuantumPrefabLink>(); but I thought that may be whats clearing it.. didn't seem to be.)

Please help!

The entirety of it gets reset, even a color field. I don't get whats happening.

[cosmic rain]

This is not a scriptable objects though.

[lean raptor]

it is, gotta scroll down, there's just multiple classes defined there

do I have to do EditorUtility.SetDirty(scriptableObject) if I'm changing values from another editor script?

[cosmic rain]

Ah, if you're editing it via code that might be the issue.

[lean raptor]

I'll try editing it through the editor and see if holds the ref

easy test i guess

[cosmic rain]

Generally, what you're editing is an instance loaded into the memory, not the actual file. When editing via code, you need to tell unity that it needs to save the changes to the file. Set dirty should work I think.

[lean raptor]

Hmm but the changes definitely appear in the editor

so it just won't actually save it unless I mark it dirty for when I close

what a strange behaviour

as if I'd want the alternative like tf

[cosmic rain]

Yes, because the editor is viewing the object in the memory.

[carmine umbra]

anyone know how to add a space between the bars in the code?

this is the code
https://hastebin.com/share/oteberenij.csharp

[lean raptor]

well fuck

I'll try it out n see

[carmine umbra]

I configured the x,y,z positions and speed but I dunno how to add space between

[cosmic rain]

If you use SerializedObject and SerializePtoperty in your custom inspector, then unity would handle the changes automatically. Otherwise you need to mark them as dirty.

[lean raptor]

SerializedObject on what exactly, the entire scriptable object or the references?

I was using SerializedField n wasnt doing anything

apparently it's the same as marking it public too

[cosmic rain]

Yeah, SerializedField is just an attribute to make the field serializable. It doesn't handle saving the changes for you. SerializedObject is a wrapper to an object field, so that if you make any changes to it, unity should handle the serialization/saving.

It should be used for the references I think. Haven't messed with editor scripting that much.

[lean raptor]

so if in that code I put SerializedObject around my types it should save it?

I'm not doing any editor scripting really

its just the scriptableobject

I have some code running that generates it using a contextmenu

but I will be moving to editor script

[cosmic rain]

You said that you modify them via code though?

[lean raptor]

ya just a context menu on a gameobject

which runs at editor time i guess

not technically editor scripting but i guess any scripts running at editor time is an editor script lmao

anyways I did a test to manualy edit the values

reloaded unity

[cosmic rain]

Try the SetDirty then.

[lean raptor]

and it kept the data

so it most definitely is this issue

looks to be fixed, thanks @cosmic rain

[nimble stream]

by removing 1 line of code which is literally just an if statement with nothing inside of it, I stopped multiple lines from a different function from printing

this is super weird does anyone know why this is happening

[winged mortar]

Show if statement that you removed ;)

[nimble stream]

i commented it out

[winged mortar]

Oh wait its a video

[nimble stream]

yea

[winged mortar]

Okay so an if statement without curly braces

And then a statement

Will be interpreted as a if with a single line in there

[nimble stream]

i tested it with a simple print too though also

[devout knoll]

Hello guys, where is the best way to ask for help, but not code wise, more about Unity - Xcode compatibility

[winged mortar]

if(something)
    Debug.Log("something");

[nimble stream]

yeah i did that too and it still happened

[winged mortar]

Is the same as

if(something)
{
  Debug.log(something)
}

What you did

By removing that statement

You will always call the next line which is something like list.remove()

Please don't send videos in the future

They are awful to look at for code

[nimble stream]

i did it with an if statement with braces and the problem still happens

[winged mortar]

Code please

[winged mortar]

No

There's the line
doublepawnsquaremove.remove

Place that in the curly braces

[nimble stream]

its not supposed to be in there though

[winged mortar]

Becuase that's the line that's conditionally ran

[nimble stream]

oh

[winged mortar]

Look at this

[nimble stream]

oh yeah it worked

[winged mortar]

This is why you should always add curly braces

[nimble stream]

my brain short circuted or smth lmao

ty

[winged mortar]

If you don't add them it'll just assume that the next valid statement is part of the if

You are welcome

[livid hemlock]

Hello, im trying to make enemy AI for my 2D bottom-up game and i cant figure out what is the best way to make an enemy dont fall from platforms and to lava, ive tried using A* pathfinding and NavMeshPlus (2D navmesh) but it is working only for 2d topdown

[prime sinew]

How about trigger colliders at the edge of each platform?

If overlapped, change direction

[livid hemlock]

thank you, i will try that

[swift falcon]

What is interpolate?
I am not really good at programming in unity so I don't even know what that is

Oh I searched on google

[lean sail]

It is an option on rigidbodies so they appear to move smoother

[swift falcon]

Well thank you for your help, you probably just fixed an issue that I had for months

[opaque lodge]

is there a way to change exit time of a specific transition in runtime

by in runtime i meant in code

[nocturne bronze]

Hello im making a game where the player is falling but im runnign into the issue where while the player is falling if they press the left/right movement key they fall slower i have a feeling its got something to do with my extremely simplified movement controller

public Rigidbody2D myRigidBody;
    // Update is called once per frame
    void Update()
    {
        if(Input.GetKey(KeyCode.A) == true )
            myRigidBody.velocity = Vector2.left * 5;

        if (Input.GetKey(KeyCode.D) == true)
            myRigidBody.velocity = Vector2.right * 5;

        myRigidBody.constraints = RigidbodyConstraints2D.FreezeRotation;
    }

is there any way to make it so that the player doesn't slow down
also im still a begginer and thats why my code is as simple as it is

[lean sail]

You are manually setting the velocity, which will essentially get rid of their current velocity

You should add to the velocity instead of directly setting it, and also limit the max speed for sure

[lean sail]

You probably should also look at beginner tutorials. U really dont need to set its constraints every single frame, or check if(bool == true) because a bool is already true or false

[nocturne bronze]

I've been trying but im struggling to keep my attention on the tutorial because it s a whole lot of listening and not a lot of doing and my concentration is at a low sooooo im really struggling to do anything

[lean sail]

You can always use the unity learn site then which is more interactive. Though with coding, you'll pretty much always have to learn something new

Otherwise try experimenting with what I suggested. Just note it's really going to be harder if you're trying to learn c# and unity by yourself through trial and error

[nocturne bronze]

im in a c# course and ive been using brackeys but im still lost at the end of the day i might take a untiy course eventualy

[nocturne bronze]

i iwll

[nocturne bronze]

I'm struggling understand how to add to the velocity

[lean sail]

Brackeys is very questionable in his coding, I would suggest a different channel but I really just havent watched any good beginner ones

[lean sail]

There is a addForce function, or you can manually add to the velocity with
+= Vector....

I would suggest just using add force, and also doing it in fixed update because that is where u want to do your physics stuff

[nocturne bronze]

ive also tried code monkey but it looks liek most of his tutorials are on his site

[nocturne bronze]

ok thanks

[nocturne bronze]

ive been playing around with boht oprions and neither of them seem to work, manually adding velocity seems to work better but the player still slows down when moving left/right

[supple oak]

Velocity is a vector, containing both sideways movement (x) and fall speed (y). If you set the whole thing to a sideways direction, you're zeroing the fall speed. Instead, make a copy of the velocity, modify the x only, and then set the rigidbody velocity to the modified vector2.

[fluid vector]

can anyone vouch for a stable websocket client library? seems like every one i find is either abandoned, only works on net core or has hundreds of open years-old issues :\

or i guess if this is XY problem if anyone knows a better way of realtime communication between unity c# and a local node.js app

[opal cargo]

Hi guys, maybe someone can tell me what I'm getting wrong in jump physics based on the GDC talk of Kyle => https://youtu.be/hG9SzQxaCm8?t=559
I made an animation curve to layout the height of a jump over time (easy parabula 0->1->0 with peak at x=0.5) and wanted to read the velocity and gravity from it to have a nice, predictable and easy to configure jump physic. But at the moment my character only stays in place and flies through the air after hitting the end of the graph.

float velocity = (2*ctx.jumpAcc.Evaluate(TimeInState)) / Mathf.Clamp(TimeInState,0,1);
float gravity = (-2*ctx.jumpAcc.Evaluate(TimeInState)) / (Mathf.Clamp(TimeInState,0,1) * Mathf.Clamp(TimeInState,0,1));
jumpDirection.y += velocity;
jumpDirection.y += gravity;

Math shows very high gravity at the start (around -200) and then decreasing, shouldn't it be the other way around?

[thin aurora]

When calling a method, you don't need to specify the type

[iron pecan]

then how should i do it ?

[iron pecan]

everywhere i looked it told me to do it like this

[iron pecan]

i don't need to write anything in test() ?

[thin aurora]

You don't pass the type, just the variable name

If this is confusing for you then I highly suggest you get used to c# as a base first. This should not be a problem when you start using Unity, and these channels are not for it

[iron pecan]

then i should just need to specify master in it right ?

[thin aurora]

[iron pecan]

i did already

[thin aurora]

Then we fixed it

[iron pecan]

except no

[thin aurora]

You know these images don't help, we need more information

A stacktrace, error message, something like that

[iron pecan]

idk if you know french

[sick stone]

||waiting for my turn to ask a question...||

[iron pecan]

The name 'identifier' does not exist in the current context

[knotty sun]

I do, you have not declared master as a variable

[iron pecan]

but somehow it wasn't a problem when declaring parameters for the method in itself ?

[celest ether]

Hi! Could someone please help my with my stupid code? 😄 I am so stuck on this fading thing and I just can't seem to make it happen.

[knotty sun]

parameters are not variables

[thin aurora]

You can ask

[celest ether]

Who could I DM? 🙂

[steep bison]

I recommend focusing on #💻┃code-beginner
The problem is better suited there so it's more likely you get appropriate help

[thin aurora]

Sorry, but we are not here to help somebody get used to c#, because there's no point in doing that since there are plenty of resources online for this. It is way easier to start with the basics of c# instead of starting with Unity while you have no experience with c# in general.

[knotty sun]

no one, make a thread

[iron pecan]

i came here as a last resort, dw i'm used to being asked to fuck off, i would'nt come here first

[sick stone]

I'm new to this ObjectPool class thing: https://docs.unity3d.com/2021.1/Documentation/ScriptReference/Pool.ObjectPool_1-ctor.html

My question is, how do I create a new pool object that is a prefab, instead of just new GameObject(), using the createFunc parameter (I'm not pro at Unity).

[unborn oracle]

hello guys i made a simple code for running but i want to shake the camera when player is moving how can i make it ? (running shake is the code for camera shake)

[iron pecan]

forget it, i'll ask chat gpt

[autumn sphinx]

ChatGPT is pretty good for Unity IME.

[iron pecan]

agree, it's helpful

good teacher

[thin aurora]

This is terrible advice

ChatGPT is not a way to learn programming

It is easy for AI to make mistakes, and there have been plenty of cases where people with 0 experience come here because ChatGPT gave them code that doesn't work

[iron pecan]

neither are unclear outdated wikis

best teacher is another person

but somehow they always bounce you for trying to learn

[thin aurora]

I assume you're talking about me suggesting that you learn c# first?

Do it for your own sake. There's no point in helping you with this issue in the first place, because you will just be stuck with the next step you take

[iron pecan]

i'm talking about absolutly anyone when you ask for help, so many forums start by sigh have you even looked it up 🙄

[autumn sphinx]

Is there a recommended resource for getting a feel for codestyle/organization best practices in unity scripts? I'm an experienced backend dev, just now getting into Unity and C#. I'm following a udemy course: https://www.udemy.com/course/unity-game-development-create-2d-and-3d-games-with-c

I'm on the first game and would like to get my habits in place early. His functions are loaded with nested if/else blocks. Is this a pretty common pattern just to avoid unnecessary computational overhead, or is breaking the code into tighter functions and objects not a huge issue for games that aren't pushing performance boundaries? Does the C# compiler inline short functions anyway?

[thin aurora]

That's because Googling is a whole skill by itself, and very often the literal question you ask can just be Googled

[iron pecan]

when the forum in itself is first result to of the search, it becomes clear many people are confused as well, and when they look for the answers like the person initiating the thread, they are met with bitterness and sufficience, which is a plague that reaches anyone with a little experience it seems

[autumn sphinx]

What's your coding experience level?

[iron pecan]

it's extremely minimal, i am brand new, i started ayear ago, but seriously got to it like, 2 or 3 weeks ago, took me a while to figure out il hooks, but finally got it because i found a pearl of a coder that was willing to give helpful advices from time to time

[thin aurora]

I agree, people are very easy with giving you a terrible, often even outdated, answer. Very often they also prefer to fix something that isn't a problem, instead of helping you with the thing you came for

[autumn sphinx]

It sucks to hear, but you're going to want to learn how to code before you try to mix code and unity. I'd probably start with python, then move on to C#. In the process you are going to have to develop your Google-Fu. The first few months of learning to code suck hard, but if you grind it out it'll get a lot easier and you'll have context for the tutorial and the docs.

[thin aurora]

But when I tell you that this is not the place for your question, it's not because I think you should Google it. I'm saying this because your question shows that you are indeed a beginner, and there are a lot of resources that will provide an infinitely better answer than I, or anybody else, ever will. I'm also saying it because I can't give you an answer in good faith, as you will most likely get stuck within seconds of fixing this. You should really get used to c# first before you start with unity

If you check the pinned post in #💻┃code-beginner , there are resources to help you get started with c#

[autumn sphinx]

https://www.udemy.com/course/the-modern-python3-bootcamp/
This one costs $30 on sale, is well structured, and you can knock it out in a month. You'll get a good feel coding, including all of the ideas revelvant to C# besides visibility and typing. You'll learn so, so much faster than trying to piece things together yourself.

[marble spindle]

why python first tho

[autumn sphinx]

It removes a lot of overhead IMO.

Once you've been coding for a while you forget just how hard it was to do things like wrap your head around a for loop. Removing as much overhead as possible allows for more wrestling with computational thinking and less wrestling with syntax.

[swift falcon]

I spent a month watching tutorials on coding and then it just snapped into my head out of nowhere.

[swift falcon]

hey anyone here can help me with this issue,so basicly i made a player and had in his script the rb.AddForce command and i stated that if u get input R button down it will do that command and it basicly works with other rigibodies but no the player,it only works when i remove the character controller from the player

btw rb is the name of the player

[latent latch]

Unity's character controller?

A CharacterController is not affected by forces and will only move when you call the Move function. It will then carry out the movement but be constrained by collisions.```

[swift falcon]

Which of these are better/faster?
I need to only get everything after the '/'

string binding = "<Gamepad>/buttonSouth"

        binding = binding.Split('/')[1];
        // or
        binding = binding.Remove(0, binding.IndexOf('/'));

// Output = "buttonSouth"```

[wide fiber]

This is script A basically acts like a input manager

public class P_Input : MonoBehaviour
{
    Vector3 moveInput;
    public float xAxis, zAxis;
    public float rotateInput;
    private void Update()
    {
        HandleInput();
    }
    void HandleInput()
    {
        xAxis = moveInput.x;
        zAxis = moveInput.z;
    }
    private void OnMove(InputValue value) => moveInput = value.Get<Vector3>();

    public void OnRotate(InputAction.CallbackContext context)
    {
        rotateInput = context.ReadValue<float>();
    }
}```

This is Script B, its for my player. This is where it executes movement and stuff that it gets from Script A
```cs
public class P_Movement : MonoBehaviour
{
    Rigidbody rb;

    P_Input p_input;


    [SerializeField] float speed;
    [SerializeField] float RotSpeed;
    private void Awake()
    {
        rb = GetComponent<Rigidbody>();
        p_input = GetComponent<P_Input>();
    }

    void FixedUpdate()
    {
        Moving();
        Rotating();
    }

    void Moving()
    {
        Vector3 movement = p_input.xAxis * transform.right + p_input.zAxis * transform.forward;
        movement *= speed;
        movement += new Vector3(0, rb.velocity.y, 0);
        rb.velocity = movement;
    }

    void Rotating()
    {
        float rotation = p_input.rotateInput * RotSpeed * Time.fixedDeltaTime;
        transform.Rotate(0f, rotation, 0f);
    }

}```

I'm trying to get it to rotate but it didnt work, it didnt rotate. THere's no error or anything. I press the Button but it didnt budge. Anyone know why? 😦

[swift falcon]

can i do some kind of addforce to the cc ?

[rigid island]

to move Character Controller you need the built in move methods

[swift falcon]

i figure it out

you need to do player.Move(-transform.forward * -5);

it does like add forcec

but it is more of a teleport

like an actual dash

[rigid island]

https://docs.unity3d.com/ScriptReference/CharacterController.Move.html

[swift falcon]

i just want to use rb.addforce but since i have a charactercontroller atttached to that gamobject i can't

[rain minnow]

Did you check that OnRotate is being called?

no lol

i wanted link for myself to pastebin

:D

but realized i can do it without

[lethal plank]

alright

[uneven monolith]

So to my own actual prohlem

//what i have(simplified)

abstract class MyClass<T> : MonoBehaviour where T : MyClass<T>
{
    T Object;
    public abstract void Init();

    public T CreateInstance()
    {
        var data = Instantiate<T>(Object);
        data.Init();
        return data;
    }
}

//what i want,
abstract class MyClass<T> : MonoBehaviour where T : MyClass<T>
{
    T Object;
    public abstract void Init(TYPEPARAM _params);

    public T CreateInstance(TYPEPARAM _params)
    {
        var data = Instantiate<T>(Object);
        data.Init(_params);
        return data;
    }
}

SO, im trying to do this kind of inheritance base script that kinda works like this ||its more complicated, and im pretty sure it is what i want in this project, so no need to judge design thx|| but idk how i could have Init/createinstance have variable amount/type of parameters, like if it was constant amount i could just use generics but it isnt,...

one solution i can think of is make the init/createinstance take one generic parameter and use it as tuple elsewhere but if there are better solutions, it would be nice because tuples can be ewwwh

[scarlet viper]

int removed = cells.RemoveAll(cell => Physics.OverlapSphere(cell.position, 0.1f).Length > 0);

how can i remove cells only if the collider belongs to a certain object ?

overlapsphere returns a collider array but inside RemoveAll i cant seem to use it

[uneven monolith]

what type is cells@scarlet viper

i can test myself

[dusk apex]

fun(arr)
{
    foreach(...)
        if(...)
            return true;
    return false 
}```

[uneven monolith]

actually using 'object's wasnt good solution, so im still avaible for ideas

[swift comet]

Why is object bad?

[rigid island]

wdym bad?

[swift comet]

Sorry, i meant as a reply to @uneven monolith

[rigid island]

nvm

yea lol

[uneven monolith]

because then when i inherit i have array of 'object' types i just have to loop throught and set them to variables, it works, but when calling that inherited init (or createinstance) elsewhere, i have no idea which positions of objectarray are gonna be which parameters so its terrible readibility

[swift comet]

Yes you're right but thats the trade off.

Cant think of another way without trading off on readability.

You could use a dictionary/hashtable in a similar way

then atleast you would have the key to fall back onto

Init(Hashtable<string, object>)

[uneven monolith]

yeah, that could work

comes with own problems (strings lol) but has much more readibility

ill experiment a bit

one more solution im thinking is doing new struct for every Init and use that but idk if that is bit overkill and waste of time

[swift comet]

Ye thats another way

Why do you need something like that in the first place (just curious)

[uneven monolith]

its actually not for monobehaviours, but for scriptableobjects(i just thought that its not very relvant for question, and ppl are more familiar with MB), so i can quickly create different scriptable objects i can create and Init on runtime, and have this Init as their 'constructor', basicly i can turn any class to scriptableobject by changing the constructor name to Init and have them inherit this

idk if its actually optimal way of coding, or overkill, but i like overkilling stuff too much(i get wierd enjoyement out of it)

[stark sinew]

I don't understand the "i can turn any class to ScriptableObject" part

why not make ScriptableObject classes in the first place?

I could type out some examples of how to do what I think you're trying to approach, but basically it sounds like you're wanting some kind of Factory pattern

Also, doesn't scale well, but why not have static factory methods on your different SOs?

[rotund burrow]

i need to project one vector onto another but only on one side. so if the angle between 2 is more than 90 i need to get (0,0,0) as a result. right now i'm just doing an angle check but i'm looking for a better way.

[fresh cosmos]

if i have a scene loaded in with async and allowSceneActivation = false, how can i cancel its loading so it doesnt become active and stops being loaded in memory?

[gray mural]

Sorry for late reply, I have replied as soon as I have tested it.
Thank you very much for your help, time and full script that you have written, I really appreciate it!
I haven't changed anything in hierarchy and applied the script you have sent, but I do think that the same issue with multiple textComponents being added as before happens.
I also believe that that's kinda bad issue of TMPro namespace, so I wonder if I should consider redacting it or doing smth there.

[eager yacht]

Strange, never hit that. Might alleviate the empties by checking if the sliced string is string.IsNullOrEmpty and what not. Outside of that, the script should let you have a more straightforward debugging process at least.

[gray mural]

yeah, I gonna try debugging it rn

[slate fern]

why am I seeing 2 Colliders off any mesh? I am using 2 cameras and if I disable the second cam it works and im only seeing one collider. Using URP also

[slate fern]

is this because every camera is rendering gizmos so if I use 2 cams I have 2 times the gizmos?

[vestal geode]

I doubt that's supposed to happen
You could try disabling gizmos from the game window

[slate fern]

well then all gizmos are gone, but if you want to have gizmos enabled you see every gizmo twice

[trim schooner]

this is a code chan, you doing anything with gizmos in code?

[slate fern]

nope but didnt found a better place to post

[slate fern]

well thanks mate

[vague slate]

Any idea what AudioSource.pitch is exactly?
How much 1f is in tones?

What I need is to calculate how much given pitch value affects clip length

[muted schooner]

Is there a way to compare a loaded AssetBundle to the local assetbundle file?

Unity knows when an assetbundle has already been loaded, so I'm sure its possible, but there's no exposed method in the documentation that I can find.

[late lion]

It's a multiplier. A pitch value of 2 will result in half the length.

[vague slate]

oh

[cunning pivot]

        slideDown = Physics.Raycast(transform.position, Vector3.down, out _slideHit, _slopeDetectionDistance, _slopeSlideLayer);
                Vector3 slopeDirection = Vector3.Cross(-_slideHit.normal, Vector3.right);
                Quaternion dir = Quaternion.LookRotation(slopeDirection);
                Quaternion slopeRotationY = Quaternion.Euler(0, dir.eulerAngles.y, 0);
                transform.rotation = slopeRotationY;

So i was trying to make the player face opposite of the slope he's sliding on and this works nice but since it uses Vector.right its in world space and not local space so if the slope is in another direction the result changes how can i fix that any help is appreciated thank you

its rotating towards the Z axis always

[vague slate]

wait a second. What would be the value of 0 or -3 mean then?

this is a default slider

[spark flower]

hello

        timerScore = timerScoreSet;

        pointsAC.keys[0].value = pointsShow;
        pointsAC.keys[pointsAC.keys.Length - 1].value = points;
        powerAC.keys[0].value = powerShow;
        powerAC.keys[powerAC.keys.Length - 1].value = power;
    }```
im trying to set some keys through code but it doesnt seem to work

[leaden ice]

define "doesn't work"

and explain what these datatypes are

because nobody can tell just from this context-free code

[leaden ice]

are these animation curves?

https://docs.unity3d.com/ScriptReference/AnimationCurve-keys.html

Note that the array is "by value", i.e. getting keys returns a copy of all keys and setting keys copies them into the curve.

[spark flower]

bothAC are animation curves

im trying to set theyr keys through code

but in the inspector they seem to be betwean 0 and 1

not changed

[leaden ice]

if you want to modify the keys you have to copy the array out, make your changes, then copy back in

as the docs say

[spark flower]

ok

works like a charm

[wintry crescent]

Hi, I'm creating a struct, and I've never been more disappointed in my life

is there a workaround to this? I really need the default values for some of the variables

nevermind I can just use a class I guess

[somber nacelle]

You cannot use field initializers in a struct before c# 10
Use a parameterized constructor or a static factory method to create the instance with your preferred values if you want to have some default values for variables on a struct

Also keep in mind that Vector3.zero is already the default value for a vector3

[wintry crescent]

that's such a shame. I guess a class works as well

[wintry crescent]

yes - but for consistency, I have defaults for all variables. Many of them have different, non-default defaults.

[late lion]

Pitch is basically a speed multiplier, which happens to change the pitch too, because that's what happens when you change the speed of a recording without any pitch correction. Negative speed means it plays backwards.

[vague slate]

yeah, I got it. Was just surprised that negative playback has 3x range vs speedup

(also very annoying it's not semitones)

[jaunty needle]

Hey guys, quick question, how do I make a piece of code run while I'm in edit mode. I want some objects to change their colour to red to easily show they're different

Hi, Im trying to set a variable, as soo as i type those two lines in update, unity and visual studio start saying that the brackets need to be closed, how do i fix this???

[muted schooner]

remove the public modifier from the 2 variables you declared

[uncut tundra]

ok

thanks, that worked

[shell scarab]

what's the difference between

where T : notnull
```and```cs
where T : struct
```?

[somber nacelle]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/generics/constraints-on-type-parameters

where T : notnull The type argument must be a non-nullable type. The argument can be a non-nullable reference type or a non-nullable value type.
structs can be made nullable so int? would be valid for the second one but not the first
hmmm seems struct also specifies non-nullable value type 🤔

[somber nacelle]

but the difference is that notnull can be a reference type whereas struct can only be a value type

[shell scarab]

IK thought reference types can't be not null

[somber nacelle]

if you have nullable reference types enabled in the project then you could use them for that. it's not super useful for unity though

here's an example: https://dotnetfiddle.net/dmFBtD
you'll notice that line 8 is perfectly valid but line 9 shows a warning that the type string? is not a valid generic type parameter for the Test<T> class

[shell scarab]

ok sorry

[weary glade]

I need help with 2D Pathfinding, I have A* set up and working. In my game I have these enemies that spawn when a player enters a room, then the enemies target the player instantly, this works fine, but i have huge lagspikes when the enemies with A* are spawned. Anyone know any possible fixes?

The lagspike is also only right when the enemie is spawned

[somber nacelle]

use the profiler to determine where performance issues are coming from

[rain minnow]

Are you constantly creating and destroying the enemies or are you using a pooling pattern with them?

[weary glade]

im constantly creating and destroying them

[rain minnow]

The profiler should nail down what scripts and methods are creating the problem . . .

[weary glade]

the profiler said: playerloop

[leaden ice]

turn on deep profiling

[rain minnow]

I'd definitely use object pooling for the enemies, especially if they share common stats/behavior . . .

Sorry, forgot. Always use deep profiling — it's invasive as fuck . . .

[slow shale]

```how do i clamp properly?(i cant clamp negative, in other words rot limitMin = -50, rotationLimitMax = 50, but when i try it in game it only works from 50-0, if it gets lower than 0 it snaps back to 50), like is there any simple way of doing it?

[leaden ice]

you'd have to show the rest of your code

it's unclear what you are doing with this variable

[slow shale]

        float newRotationY = gunnerPivot.transform.localEulerAngles.x + Input.GetAxis("Mouse Y") * 100 * Time.deltaTime;

        newRotationY = Mathf.Clamp(newRotationY, rotationLimitMin, rotationLimitMax);
        gunnerPivot.transform.localEulerAngles = new Vector3(newRotationY, newRotationX, 0f);```

[leaden ice]

i think you have your x and y mixed up

wait maybe not?

[leaden ice]

wait yes it's mixed up

you should be clamping the x rotation

[slow shale]

i am clamping the x rotation

[gaunt blade]

Yes I know it's not in snippet form, it's because I wanted to highlight things with a box and you cannot do that in a code snippet.

I'm confused why the compiler is determining the data type of "map[key] to be a "Geometry.Triangle" object when it's clearly defined as being a List<Triangle> object. Anyone know why this is happening?

[slow shale]

if i put the value in 50 and 10 or -60 and -10 it clamps correctly

[leaden ice]

ok yeah sorry - i think that's ok. But you're subject to gimbal lock doing things this way

[leaden ice]

yeah because you're doing this based on reading the euler angles back from the transform

that's not going to work properly

you might get -15 or you might get 345

they're equivalent

[slow shale]

so how do i fix it?

[leaden ice]

you need to drive the rotation with your own variable instead of teading it from the transform

[gaunt blade]

I did use var, and when I attempt to treat the object like a List, it treats it like a Triangle object

[slow shale]

uhm, can you maybe explain in a more noobish way :))

[gaunt blade]

For some reason it's identifying the object as the wrong data type

I don't understand why

[simple egret]

Hover over map, what data type does it highlight?

[leaden ice]

something like this

float pitch = 0;
float yaw = 0;

void Update() {
    yaw -= Input.GetAxis("Mouse X");
    pitch += Input.GetAxis("Mouse Y");

    pitch = Mathf.Clamp(pitch, rotationLimitMin, rotationLimitMax);
    gunnerPivot.transform.localEulerAngles = new Vector3(pitch, yaw, 0f);
}```

[gaunt blade]

It's very clearly defined in the class field as being a List<triangle> object

[leaden ice]

Also @slow shale you should NOT have deltaTime in there

it's incorrect

[slow shale]

whats wrong with deltatime?

[leaden ice]

mouse input is already framerate independent
adding it here is going to make it jittery and weird

[somber nacelle]

you are foreaching the list there, so each individual element is a Triangle. if you were just doing something like var list = map[key] then yes, the data type would be List<Triangle>

[simple egret]

No, in the foreach

[gaunt blade]

Still a List<Triangle> object

[slow shale]

alrighty

[simple egret]

But yeah, you're indexing the dictionary, which gives you a list, then foreach iterates over the list, giving you a Triangle

[slow shale]

works perfectly, ty ❤️

[gaunt blade]

Ooh, I see what you mean.

Wait

no I don't

[somber nacelle]

what is the type of map[key]

[gaunt blade]

I'm confused. The first foreach loops over the keys in the Dictionary, and "key" is the individual key.

The second loops over each key-value pair in the Dictionary, and the value should be a List object

So it should return a List

[somber nacelle]

right. so what do you get when you foreach a List<Triangle>

[simple egret]

That double foreach is not really efficient btw, you can only use one on the Dictionary itself, which will yield some KeyValuePair<TKey, TValue>, that you can use .Key and .Value on

[leaden ice]

stop using var

it's making your life hell

because you don't even know what type your variable is

[gaunt blade]

I don't use var, I only added it to prove a point to someone who said to add it

You can see I never use it

[leaden ice]

yes this shows that the type is wrong more clearly

var gets rid of the compile error at the expense of you being confused

becuase Triangle is what should go there

[gaunt blade]

So I should be doing "in map" instead of "in map[key]"

[leaden ice]

what are you trying to do

[eager yacht]

foreach ((Vector2 key, List<Triangle> value) in map) {
  foreach (Triangle tri in value) { 

  }
}

[leaden ice]

map = CreateMap(triangles);
foreach (Vector2 key in map.Keys) {
  List<Triangle> triangles = map[key];
  foreach (Triangle t in triangles) {
    // do stuff
  }
}```
Is this more clear @gaunt blade ?

[gaunt blade]

The hashmap is for generating a barycentric dual mesh. The Dictionary contains every point on the grid, and the value is the Triangles that contain that point as a vertice.

[gaunt blade]

So how do I loop through all the keys and get the list itself

[leaden ice]

just like how I showed?

notice the triangles variable is a List<Triangle>

that's the list you want, yes?

[dusk apex]

Couldn't you just loop through all the values and acquire the lists?

[gaunt blade]

Ah I see what you mean now

[hexed oak]

will a serialized C# dictionary deserialize into a std::map?

[leaden ice]

depends on how you serialize it and deserialize it

if the serialization format and CPP library for deserialization are compatible, sure

[plain moon]

How to make that effect. It's all 3D objects around even dashboard with shifter and steering wheel

How he's highlight it

[dusk apex]

Doesn't look like a coding question.

Try asking #💻┃unity-talk

[echo plaza]

Hey there, I was wondering how I could set the .WithControlsExcluding() from outside the code, since I have to different places to set keybinds, one for a keyboard and mouse, and the other for a controller. I can't do an if statement or a foreach loop so I was wondering if anyone had any idea what else I could try. Here is a snippet of the code, where if I try doing the if statement or foreach loop I get the error "Does not exist in the current context".

            // Configure the rebind.
            m_RebindOperation = action.PerformInteractiveRebinding(bindingIndex)
                .WithControlsExcluding("<Keyboard>")
                .WithControlsExcluding("<Mouse>")
                .WithControlsExcluding("<Gamepad>")
                .OnCancel(
                    operation =>
                    {
                        action.Enable();
                        m_RebindStopEvent?.Invoke(this, operation);
                        m_RebindOverlay?.SetActive(false);
                        UpdateBindingDisplay();
                        CleanUp();
                    })

[leaden ice]

you can definitely use a loop

[upper fjord]

why is it that when I import my model it's not the right way round?

[leaden ice]

var operation = action.PerformInteractiveRebinding(bindingIndex);
foreach (string exclusion in exclusions) {
  operation = operation.WithControlsExclusing(exclusion);
}
operation = operation.OnCancel(blah blah blah);```
The "Does not exist in the current context" error means you tried to use a nonexistent variable somewhere.

[leaden ice]

not a code question. #🔀┃art-asset-workflow, but basically you exported it wrongly for Unity

[lean sail]

probably change your export settings, but ask in a channel more related to assets..

[upper fjord]

sorry

[river kelp]

Hey, I had some issues that forced me to upgrade to 2022 LTS from 2021 LTS. As expected this is a bit bumpy, but I have encountered something I can't really find a reason for. In the editor, I get the error "The name "Handles" does not exist in the current context" upon booting the game, although it appears to run just fine.

Intellisense finds Handles just fine

[somber nacelle]

you missed something on line 69

[river kelp]

Line... 69?

[somber nacelle]

oh sorry, since you didn't provide any actual information i assumed you just wanted us to make random guesses

[simple egret]

default(int) // 69

[river kelp]

I thought I provided the actual info..
Here is an example of a line using "Handles"
Handles.DrawWireArc(source.transform.position, Vector3.forward, startVector, aimBallAngle, 19, 5);

it's in "OnDrawGizmosSelected"

Visual studio finds handles just fine, and it compiles and runs, but I get this:

[thick terrace]

handles is an editor class while the other gizmos drawing stuff isn't so you might need to put an #if UNITY_EDITOR around that line?

[river kelp]

I know handles are a special class, like they are an editor only class right?

that would make sense but I'm in editor..

[swift falcon]

I am getting ~30 second compile times despite it being a relatively new project, my last project was a full massive game and only has compile times of ~18 secs
I'm worried it's because of the "Singleton" class I made for loads of managers:

public class Singleton : MonoBehaviour
{
    public static Dictionary<System.Type, Singleton> Instances = new Dictionary<System.Type, Singleton>();

    protected virtual void Awake()
    {
        if (!Instances.ContainsKey(GetType()))
        {
            Instances.Add(GetType(), this);
            return;
        }

        if (Instances[GetType()] == null)
        {
            Instances[GetType()] = this;
            return;
        }

        enabled = false;
    }

    public static T Get<T>()
        where T : Singleton
    {
        if (!Instances.ContainsKey(typeof(T)))
            return null;

        if (Instances[typeof(T)] == null && Application.isEditor)
            throw new System.NullReferenceException("Singleton Get returning null!");

        if (Instances[typeof(T)] is T instance)
            return instance;

        throw new System.Exception("Instances contains mismatched key-value pair: " + typeof(T).Name + " " + Instances[typeof(T)].name);
    }
}```

Have I made a horrible mistake? 
Get() has 63 references alone
There are probably close to 30 classes inheriting from Singleton

[river kelp]

and, this wasn't an issue prior to upgrading to 2022 LTS

very unlikely that it has anything to do with the number of things that reference a particular function

[river kelp]

I can, I'm just not sure why any of it would be relevant. Like the code compiles and runs, I'm just wondering if anyone knows why the editor suddenly complains about not finding the handles class

[swift falcon]

Any idea why I could be getting higher compile times than usual? I have all the same stuff as my last game, URP, TextMeshPro, etc

I tried messing around with Assemblies but tbh my game is pretty messy with dependencies, not much I can do.

It feels like something is wrong though, my game isn't big enough to have compile times this large yet

[leaden ice]

compile time, or build time?

[swift falcon]

Compile time, making a change to a script and then entering the editor

[swift comet]

Do you make use of namespaces?

[swift falcon]

No do you think that would help?

[swift comet]

Ofcourse

[swift falcon]

If I change the value in the project settings will it automatically update all my scripts?

[somber nacelle]

namespaces are irrelevant to compile times. it's assemblies that help reduce compile times

[swift comet]

May not make much difference if there isnt much code Oops ye my bad, namespaces dont matter.

[river kelp]

Apparently I can just #if UNITY_EDITOR the whole section and it works, although the code does get called from the editor

[swift falcon]

Here's my github for the project, I don't expect anyone to properly look through it but if you have an idea of a possible problem you could check here:
https://github.com/CloudyUnity/dreamstar-terminus

[leaden ice]

sounds like somehow it's compiling for a build not for edit mode

[river kelp]

maybe 2022 contains an assert-y thing to confirm no code editor-only code is in a state where it would mess up a publish

[leaden ice]

if you're doing a build, then it will of course fail

Handles has never been accessible in a build

[river kelp]

I'm not doing a build, just running editor

pressing play, etc

[heady iris]

yeah, you should peek at the symbols that are defined

[leaden ice]

that's odd then, yes

[river kelp]

The code is built, it runs, I can get break points to hit handles and it works

the handles stuff is drawn to the screen..

So that means it must be some kind of safeguard, right?

Maybe Unity got tired of the 250 questions they got every day about the same thing

[swift falcon]

I've seen a few mentions of disabling "Reload Domain"
This is disabled right? This was the default for me

[river kelp]

and if editor fixed the issue so.. maybe I'll just be more careful

[river kelp]

lemme check this

[heady iris]

This is the default setting.

Reload Domain and Reload Scene are both going to happen.

[somber nacelle]

i would strongly recommend against disabling domain reloading if you don't want to manually reset your static variables

[heady iris]

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

[heady iris]

You can also have problems with some packages.

Notably, I've experienced crashes with the Input System with domain reloading disabled after updating an input action map

specifically, when trying to get display strings for bindings

[river kelp]

I have the same here as you do

appears to be my default settings

[ashen yoke]

enable play mode options and nothing else

[swift falcon]

Didn't seem to make any difference anyway, still about 30 secs

[ashen yoke]

and it will disable both reloads

[swift comet]

Get more RAM or better CPU 😅 SSD would help a lot.

[soft shard]

If you made a completely new project with absolutely zero assets, scenes, ect, and made just 1 single script in the room Assets folder with nothing else, then make a change, about how long is your compile time then? If its somewhat close, it may be a different issue than asset-specific

[ashen yoke]

@swift falcon tho i advice to keep scene reload enabled

[swift falcon]

My previous project was waaaaaay bigger than this one and is ~18 secs compared to ~30 secs

[ashen yoke]

so did you do it? its works?

[swift falcon]

Yeah I did what you said there, took about 3-4 secs off but nothing major

[ashen yoke]

then its not domain reload that eats up time

do in empty scene

[swift falcon]

While the new project is loading, I read somewhere that newer versions of Unity have faster compile times
I'm using v2020.3.25f1 right now
Is it worth it to upgrade?

[ashen yoke]

why new project

new scene

in the same project

the gains of "compile time" by unity are marginal

[swift comet]

Is your project on SSD? or HDD?

[ashen yoke]

compile time is very fast, if it was only compile time you would have 3 second compilation on massive projects

the issue is that after compile it does domain reload

and that take very long time and even with their changes it barely affects anything

[swift falcon]

New scene: 35 secs
New project: <5 secs

[ashen yoke]

new scene in the same project 35 seconds only to enter playmode?

and you are certain you have domain reload disabled?

empty scene with no domain reload should instantly enter play mode

[swift falcon]

Not to enter playmode. If I change a script, save and then re-enter Unity it takes 30-35 seconds before I regain control

[ashen yoke]

see whats written on that option?

[swift comet]

It really depends on PC specs too

[swift falcon]

That was with Play Mode Options disabled

[ashen yoke]

its says Play Mode

there is nothing about compilation there

you cant skip domain reload on compilation this option doesnt affect it in any way

[heady iris]

i'm not sure if there's a way to profile what's taking up time in the compile -> reload process

[ashen yoke]

domain reload what else

[heady iris]

well, yes

[ashen yoke]

and that is affected directly by drive/cpu/ram

[heady iris]

but the question is whether something is taking up an abnormal amount of time in that process

[ashen yoke]

if empty project takes 5 seconds id say its pc specs

i get 1-2 seconds on empty

@swift falcon disable that option back to default state

[swift falcon]

My previous project had over a year of development on it
This project has about 3 weeks

There's no way there's not something weird going on here

[heady iris]

time spent developing does not correspond to the amount of work that has to be done

if you think there is something that's taking an abnormal amount of time, you could search for it by creating a new project and then bringing script assets over to it

[swift comet]

Can always call this in editor code to see if your compilation takes long CompilationPipeline.RequestScriptCompilation();

[swift falcon]

Sorry that took so long, using a stopwatch it took about 41.54 seconds

Which seems a bit insane

[swift comet]

Is the project on SSD?

[west path]

how do i make mesh data (verts / triangle) in a unity job from a noise map

[swift falcon]

It is yes

[swift falcon]

I want to bring attention back to my first thought, are we sure this web of dependencies is not a possible cause?
Assuming all my scripts are under the one assembly the compile times shouldn't matter on the dependencies right?

It's one of the only differences between the two projects

In my main assembly there are 51 scripts, 30-45 second compile time
In my previous project with no custom assemblies there are 203 scripts, 18 second compile time

hm, ok
I restarted the project, closed all other projects and suddenly the compile time is back down to a few seconds

So...problem solved I guess
Anyone know what could have been going on in the background there?

[knotty sun]

unfortunately these numbers are irrelevant

[knotty sun]

only you, it's your computer

[dusk apex]

Only thing I can think of is if you've got assembly definitions referencing the Singleton, modify the Singleton would have all dependencies recompile.

https://youtu.be/eovjb5xn8y0

[swift falcon]

Everything outside my main assembly has no dependency on anything inside the assembly, if that's what you mean

Maybe leaving the project open for multiple days had something to do with it
I'm not gonna get too bothered about why it happened, at least it was a good learning experience

[swift comet]

multiple days

[swift falcon]

Is that not normal lol?

Whoops

[swift comet]

I almost said did you close the project recently

[swift falcon]

Well thanks everyone for the help anyway lmao

[heady iris]

well, more generally, if you modify an assembly, all assemblies that depend on it get recompiled

singleton or otherwise

[lean sail]

I used to leave it on overnight, until one day my pc crashed while I was asleep and there was a major bug in my project (which I assume was due to unity not shutting down properly). So I'd advise closing it when done, performance reasons aside

[ashen yoke]

always commit your work when you finish working

at least stage it

[heady iris]

i'm bad about not committing partway through an implementation

i should just squash them before pushing

[ashen yoke]

just commit, no need to push

[swift comet]

I quite like perforce because of that, its all CLs no commits 😅

[ashen yoke]

in the morning you can push it in a new branch if needed

[earnest gazelle]

How do you implement fog of war in voxel games? The voxels should get visible if they are close to npc characters.
Add a boolean field for each voxel named IsVisible and consider a range?
Then the voxel shader uses isVisible voxel data to show/hide them?

[heady iris]

oof, that's a tricky one

making it performant, at least

[ashen yoke]

full 3d?

or projected from top masking

you can for example have a sphere on each npc that sets stencil value

then camera from top renders the scene using that stencil value into a texture which is used by voxel shader to drive color

[earnest gazelle]

Like minecraft

[ashen yoke]

minecraft doesnt have fow

[earnest gazelle]

Yes, it can contain float voxels as well

[heady iris]

well, a game like minecraft

but with fog of war

[ashen yoke]

yes that i understand my question still stands

full 3d fow means you have full voxel volume to process, with problems like occlusion

[earnest gazelle]

I think it does not work in my scenario

[heady iris]

yes, adding that extra degree of freedom leads to...

fun (tm)

[earnest gazelle]

It is full 3d voxel game with sparse voxels in different heights

[ashen yoke]

its going to be a nightmare

there probably is some whitepaper with efficient algorithm for that

something along bresenhams line but for 3d

[earnest gazelle]

Also, if a voxel gets visible, it will be visible forever

[ashen yoke]

still

[earnest gazelle]

Why nightmare?
My approach does not work?
Add a boolean field for each voxel named IsVisible and consider a range?
Then the voxel shader uses isVisible voxel data to show/hide them?

[ashen yoke]

well there is stencil based occlusion technique which is supposed to be very performant, maybe that can be applied somehow

but that requires camera

otherwise maybe raycast in a Job

do massive amounts of raycasts

[earnest gazelle]

You mean to hide/show items on voxels or just render voxels as black voxels or normal voxels?

[ashen yoke]

to flag voxels and not flag occluded voxels

rendering that should be relatively easy

you can use Texture3d

[earnest gazelle]

Yes, just set black color to hidden voxels is really easy but showing/hiding 3d items, enemies, npcs on those voxels are nightmare

[ashen yoke]

check stencil occlusion

[earnest gazelle]

thanks

[ashen yoke]

https://github.com/przemyslawzaworski/Unity-GPU-Based-Occlusion-Culling

or easier

you can sample the nearest voxel

if the voxel is visible so is the object

[earnest gazelle]

To show/hide 3d elements (items, enemies, etc.) on voxels, I can check if they are on hidden voxels or not, then based on that, render them or not. I think it would be OK

[ashen yoke]

hivemind

tho stencil occlusion here would work just as well imo

since you have a special case where only thing writing into buffer is voxels

or rather the only thing occluding

[earnest gazelle]

:/ but it would not be ideal. Suppose an enemy moves from a hidden voxel to visible one.

[ashen yoke]

and what happens?

[earnest gazelle]

It renders completely after going to the visible voxel

[ashen yoke]

right, so you have to keep updating known voxel state on move

not only known flag, but also currently visible flag

is it realtime?

turnbased?

you can update on move and at custom tickrate

say 4 times a second

[earnest gazelle]

I mean the model (mesh) is completely visible or hidden not parts of it hidden and the other parts visible in voxel edges

[ashen yoke]

in a job, and on a separate voxel structure that only stores visibility flags

[earnest gazelle]

It is a city building game

OK, I test it. I think it is OK to render objects or hide them I mean the full body. Appreciated.

Hey there, I was wondering how I could change this script so that it only removes the custom keybinds for either a keyboard and mouse or a controller.

using System;
using UnityEngine;
using UnityEngine.InputSystem;

public class ResetAllBindings : MonoBehaviour
{
    [SerializeField]
    private InputActionAsset inputActions;

    [SerializeField]
    private Boolean gamepadRebind;

    public void ResetBindings()
    {
        foreach (InputActionMap map in inputActions.actionMaps)
        {
            map.RemoveAllBindingOverrides();
        }
        PlayerPrefs.DeleteKey("rebinds");
    }
}

[rain minnow]

Store a copy of the original bindings. When you remove all bindings, assign the original copy back . . .

Hello, I want to be able to check the RGBA values of the set of pixels from a 2D texture on a model that a collider is colliding with. How can I achieve this? I think I might have to use Texture2D.GetPixel() but I don't what x and y coordinates I should check based on the collision. If it helps, the collider is spherical

[quartz folio]

https://docs.unity3d.com/ScriptReference/RaycastHit-textureCoord.html

[bitter cape]

Oh snap! This is really cool, thanks!

[quartz folio]

Just do note the caveat that it only works with Mesh Colliders

[blissful crater]

Hi!

[bitter cape]

Gotcha

[bitter cape]

I'm trying to use this to detect the colors directly under the player but for some reason the color it's detecting doesn't properly align with what's under the player. It seems to be offset and scaled for some reason

My code is:

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

public class PaintDetector : MonoBehaviour
{
    private void Update()
    {
        RaycastHit hit;
        if (Physics.Raycast(transform.position, Vector3.down, out hit))
        {
            Paintable paintable = hit.collider.gameObject.GetComponent<Paintable>();
            if (paintable != null)
            {
                Texture2D tex = toTexture2D(paintable.getMask());
                Color color = tex.GetPixel((int)(hit.textureCoord.x * tex.width), (int)(hit.textureCoord.y * tex.height));
                Debug.Log(color);
            }
        }
    }

    Texture2D toTexture2D(RenderTexture rTex)
    {
        Texture2D tex = new Texture2D(512, 512, TextureFormat.RGB24, false);
        // ReadPixels looks at the active RenderTexture.
        RenderTexture.active = rTex;
        tex.ReadPixels(new Rect(0, 0, rTex.width, rTex.height), 0, 0);
        tex.Apply();
        return tex;
    }
}

[quartz folio]

Regardless of the offset, this is a memory leak, you are constantly creating new Texture2Ds, you need to call Object.Destroy on them when you are done with them, otherwise you're just accumulating them

[bitter cape]

Ah, I thought C# had a garbage collector that would just handle that

[quartz folio]

Texture2D's are UnityEngine.Object types, which are mostly native objects

I'm not sure what your entire setup is, it could be doing that for all sorts of reasons, like offsets defined on your material or in your shader, which are not taken into account by hit.textureCoord

Also note that

Paintable paintable = hit.collider.gameObject.GetComponent<Paintable>();
if (paintable != null)

can just be

if (hit.collider.TryGetComponent(out Paintable paintable))

Damn, I should get you to do a code review for my whole project lol

[molten sandal]

Good day community, I am here to ask if some one has a good guide or documentation about wolrd and local space because I am struggling a lot with properly understanding how they work and how to transfomr from one to another

I have an object tree like this:
Player 1
|--- Vehicle
|--- Camera

I need a simple script attached to the camera that will target the vehicles and for now just a simple function that will keep the camera behicnd the vehicle minus a configurable offset

using UnityEngine;

public class VehicleCameraController : MonoBehaviour
{
    public Transform target;
    public Vector3 offset;

    private void LateUpdate()
    {
        transform.position = target.position - offset;
    }
}```

Like this

but those calculations are in world space

[heady iris]

local space is from the perspective of the object

if you want a position 10 meters behind an object, you need to get a vector that points backwards (from the object's point of view), then scale it and add it to the object's position

e.g. target.position - target.forward * 10;

Transform.forward is a world-space vector that points in the transform's forward direction

in local space, that vector is always Vector3.forward

because from your POV, forward never changes

it's just...forward

[molten sandal]

Ok, thanks, let me try

And a would like to ask for an advice

because most of the issues I am having are probably because I don't know if should I make the calculations in world space or local space or it depends of the case

[heady iris]

you must know which space you're working in

for any Transform, you can convert from world -> local and local -> world

[heady iris]

in this case, everything was done in world space

you could also do it in local space

target.TransformPoint(Vector3.back * 10)

Vector3.back is [0,0,-1]

we scale it to [0,0,-10]

then we use Transform.TransformPoint to convert it from local space to world space

Although, this would be wrong if the transform was scaled at all.

you can see this for yourself by parenting two cubes together, offsetting the child, and then scaling the parent

the child moves

[heady iris]

This would be the most straightforward way to do it.

[molten sandal]

OK ok, I get it thanks

For the problem I have right now is that I need to make a camera controller that follows a high speed hovercraft over a track, such hovercraft can yaw, pitch, roll and turn basically to any direction, for this specific problem do you recommend doing all the calculations in world space or local space?

[heady iris]

well, I would recommend just using Cinemachine

[molten sandal]

hm...

[heady iris]

it's a great camera control package

[molten sandal]

I got it

I tried it

and I face a problem that I was not been able to solve

by any mean

When using a smooth transform like lerp or slerp that makes the camera to try to follow, the faster the object moves, it takes the camera longer to reach the object, so it starts to get left behind

[heady iris]

you don't have to move the cinemachine virtual camera yourself

you just use the Transposer mode

[molten sandal]

This is not very notorious for low velocity, but it is a problem for velocieites with a magnitude > 1000km/h

[molten sandal]

ok ok, let me check

[gaunt blade]

Does anyone have some suggestions on how to optimize memory usage

I feel like just what's on the screen should not be taking up 6.6GB

With this type of memory usage there's no way I can do a map generation algorithm. This data needs to be much much smaller.

[quartz folio]

Use the memory profiler to see what's actually in memory https://docs.unity3d.com/Packages/com.unity.memoryprofiler@latest/
You've probably screwed up and are not destroying meshes you've made previously

[gaunt blade]

Gracias

[gaunt blade]

For some reason there's a ton of reserved memory

Do you have any idea why it'd be reserving so much memory. I don't have 5GB of memory to just throw into unity for the sake of it

[quartz folio]

You likely allocated that amount of memory previously

Restart Unity and take a look at the size of the memory pool when you've only done the thing once

If you've not been destroying objects correctly then you've perhaps allocated a large amount, causing the memory pool to enlarge, but Unity managed to clean it up at some point when Resources.UnloadUnusedAssets was called automatically

[gaunt blade]

How am I suppose to destroy objects correctly?

Yeah it's a lot better after restarting the editor

But I'm confused what I'm doing wrong to have it keep reserving memory over and over.

[quartz folio]

whenever you new a UnityEngine.Object like Mesh it is up to you to call Object.Destroy on it when you are done with it

GameObject and Components in the scene are the exception

[stark sinew]

Whoa, i've just learned something after literally years that sounds quite important 8)

[quartz folio]

There are other things that allocate new objects, like calling render.material, and it's also up to you to destroy those materials too

[gaunt blade]

Would GameObject components count as UnityEngine.Object stuff?

[gaunt blade]

That'd do it

[quartz folio]

Yes, GameObject and Component are UnityEngine.Object, but they will be destroyed when the scene is, so you don't have to do anything about it

but assets like Materials, Meshes, RenderTextures... they will only get destroyed when you call Object.Destroy. They may also be destroyed if they are not referenced when a scene is loaded non-additively beacuse that calls Resources.UnloadUnusedAssets

[gaunt blade]

So in this case, should I be calling "color.Destroy()" at the end of the function

[quartz folio]

Color is a struct, it's not a UnityEngine.Object subtype

Also, new LineRenderer() is invalid code, AddComponent is already creating the LineRenderer

There are other easy ways to allocate loads of memory when dynamically creating meshes that are not memory leaks. Accessing mesh.vertices or similar properties will allocate an entire array of Vector3's every time it's called. A common mistake is to write code like:

Vector3[] vertices = mesh.vertices;
for (int i = 0; i < mesh.vertices.Length; i++)

which is incorrect because now it will allocate a whole new array on every iteration of the loop to check the length.

[gaunt blade]

So you want to create a container before the loop and repeatedly refernece that container so it's only generating a single one instead of generating new ones over and over

I might be doing that

Or does that only apply to meshes?

[quartz folio]

It only applies to mesh properties

Many properties on UnityEngine.Object subtypes will have similar behaviour though

[gaunt blade]

I must be doing something like that because my memory usage shot up from 2.2GB to almost 7GB the second I clicked play

Yeah it has to be something along those lines

[bitter cape]

In this screenshot you can see the console that is showing RGBA value at the specific point (0.7, 0.64) and on the bottom right is texture it's pulling from. I did the math based on the pixels but it's still not adding up

Based on the hit.textureCoord that's getting logged, the RGBA value should NOT be all 0's here, yet it is

[quartz folio]

I'm suspicious that this texture is 1024 while your code is 512

[bitter cape]

what do you mean the code is 512

[quartz folio]

#archived-code-general message

Texture2D tex = new Texture2D(512, 512, TextureFormat.RGB24, false);

Though I can't see your complete setup or whether or not the texture is the same one you create here, just some code has changed. But it's those sorts of discrepancies that can cause your issue

[bitter cape]

OH! I'm so stupid, that line should have been Texture2D tex = new Texture2D(rTex.width, rTex.height, TextureFormat.RGBA32, false);

I just changed it and now it works!

Thank you so much!!!

[night harness]

Not sure where the best place to ask this is but any suggestions on where to get assistance with DOTWeen Pro? Having a terrible time with it

[prime sinew]

I guess here

Any of the code channels

[night harness]

I've been really struggling on how to actually use it, The documentation seems super lackluster. Currently I have some DOTweenAnimation's and I'm trying to run them via code and run a function on complete when it's done but I can only find examples of doing that with a specific tween function rather than a DOTweenAnimation

[prime sinew]

Have you found the documentation?

I'm afraid I don't know what a DoTweenAnimation is, so I can't help

[night harness]

Are you just meant to either exclusively use the inspector based DOTween Animations and chain via drag and drop or exclusively do it all in specific code based tweens, I've found very little on the combination of both

[night harness]

Yes.

[prime sinew]

Best to also show the code

[night harness]

An example of what I want to do is something like

leftObjectiveUI.primaryLoadTween.OnComplete(() => ClearObjectiveUIData(ObjectiveUIPreference.Left));

or

leftObjectiveUI.primaryLoadTween.DOPlayBackwards().OnComplete(() => ClearObjectiveUIData(ObjectiveUIPreference.Left));

Ah right that worked

[oak tusk]

Gotcha! Give me a couple mins and I will! Thank u’

[lean sail]

you can just encrypt the string. Also 2 lines of your if statemnet happen in both conditions so u can just take it out

i also dont think u want to use File.Encrypt.. i believe its only on windows but i could be wrong. This is just from memory

[cobalt gyro]

do you know of a encryption system that works univerally

[lean sail]

should be able to use this, and just encrypt your string itself
https://learn.microsoft.com/en-us/dotnet/api/system.security.cryptography?view=net-7.0

though I would at least look at a high level overview of how encryption works, for whichever algorithm u choose. AES is popular

[cobalt gyro]

ight

thanks

[lean sail]

also just to note, this will pretty much only deter people from editing the written file. Local encryption is pretty much impossible to make secure

are there any known popular libs that have TypeID attribute

i dont want to create name collisions in the future

doesnt matter ill rename if they happen

[leaden solstice]

Namespace it?

[ashen yoke]

its going into one of the most commonly used namespaces project wide, so collisions on name are almost guaranteed

i trade availability for potential collision in the future

Hello, kinda wierd question but what you think would be better name for showing additional windows in UI:

1. ToggleWindow(bool)
2. ShowWindow(bool)
3. TurnOnWindow(bool)

[lean sail]

ShowAdditionalWindows(bool)

the way u described it was so we could understand the context, the function name should do the same to someone reading it for the first time

[jovial spindle]

Yea I agree, just had trouble wrapping my head around but got to same conclusion. Thanks! 🦆

[ashen yoke]

is there some non alloc version of GetCustomAttributes?

allocating an array for each type in the project is overkill, what is this api

[primal wind]

If I remember correctly you can just call it on the assembly itself

[ashen yoke]

it returns bare attributes or attributeData

both dont provide type they are bound to

public static Attribute GetCustomAttribute(Assembly element, Type attributeType, bool inherit)
{
     Attribute[] customAttributes = Attribute.GetCustomAttributes(element, attributeType, inherit);

[spark flower]

can i check just a dot for a collision and not an entire ray?

[lean sail]

yes u can, 2d or 3d though?

[spark flower]

3d

[lean sail]

you would be checking more if a point was inside a collider
Physics.OverlapSphere(some position, 0f) should work

[spark flower]

what do you mean

[lean sail]

you can check if the OverlapSphere hit anything, and i guess u could also just use the nonalloc version

My RawImage displaying the RenderTexture is on a canvas with the mode Screen Space Camera, without any camera gived to the Camera field.
My Canvas displaying my Map is on a World Space Canvas, directly on the scene, with the camera displaying the render texture on top, as its parent.
I tried this :
https://gamedev.stackexchange.com/questions/198782/how-do-you-get-the-texture-coordinate-hit-by-the-mouse-on-a-ui-raw-image-in-unit

But the coordinates are wrong. (Not upside down, really wrong).

I tried this as well: https://forum.unity.com/threads/interaction-with-objects-displayed-on-render-texture.517175/
Changing eventCamera by the Camera displaying the renderTexture since I needed my canvas displaying my RenderTexture to be in WorldSpace for it to function, and I cannot do that in my project.

I tried a bunch of other stuff as well, but these were the ones where I had the best results so far (But both doesn't work...)

Anyone could help me please ?

Sorry for my mistakes, I'm not english ^^"
Thank you very much !

Hi guys,

I'm stuck with collision detection in 2D.

I have two game objects, A & B.

I want to trigger logic when A collides with B using onTriggerEnter2D - However when they collide, nothing happens?

Both have colliders and both colliders are set as triggers. Any help would be greatly appreciated 🙂

[latent latch]

One needs a rigidbody, but you can set it as kinematic

[molten thicket]

So if one is a door and the other an enemy - Would the enemy have the Rigidbody? or does not matter?

(Thank you)

[latent latch]

Ah, if it were like a coin to pickup, I believe you want to make a collider on the character the trigger, and the coin the object with the kinematic rigidbody + non-trigger collider

[molten thicket]

That's useful - Did not know that. Will give it a spin 🙂

[urban estuary]

Hmm would anybody be willing to lend a hand with a wierd issue im running into, basically I've run a BoxCast underneath a 2D player that toggles a bool on and off this works perfectly, However I also use this bool to set the parameters of my physics2d material and it changes the friction from 0.04 the default to 0.0 when in the air so the player can't stick to the wall however it doesn't seem to actually update any of it even though the material is definitely on the player is there a different method im supposed to use here?

to note I can physically see the changes happening inside the inspector and the physics material is on my 2dbox collider

[latent latch]

https://docs.unity3d.com/ScriptReference/Collider-material.html

Create instances of the material and swap it out depending on the situation

https://forum.unity.com/threads/change-the-bounciness-of-physics-material-2d-randomly.660673/#post-4423300
bit more insight from this post. They behave similar like normal shader material where there's a persistent instance of it, so you'll always want to create a copy or use two different materials when you want different values.

Apparently attaching the phyics material directly to the rb, it updates all colliders to it which I didn't know

[delicate moon]

If anyone is interested, I did find a solution, I'll tell you if needed.
Thanks anyway.

[drifting crest]

I want to load one object from first scene to another with all the refrences in it , currently I am using don'tdestroyOnload the object is getting loaded but the refrences in the inspector given from first scene are gettting delted how can I load them as well?

[thin aurora]

#archived-networking

[harsh ridge]

oh mb

[thin aurora]

You probably get a quicker answer there

[ruby fulcrum]

why does transform.getcomponentsinchildren only get one instance when i have 15 instances, the objects are being made by pooling (instancing) 15 times in start from a prefab

[delicate moon]

You can't keep references to a scene from another if it's something unique in the scene.
If it's a int, or a string you need, create a value in the script you put on DontDestroyOnLoad and assign the value from the first scene to the value on this script, it should work.
If it's a game object, I don't really know, use a prefab maybe.

[ruby fulcrum]

nvm fixed it

forgot to enable include inactive

[bold flare]

Good afternoon!
Is there a way to destroy a gameobject or component (like a script attached to a gameobject), and make it not reappear? If not, which value (like a reference to the destroyed objects) can I store in my save file to destroy the objects again on game load?

Thanks! 🙏🏽

[latent latch]

Which do you want to destroy, a gameobject or component

https://docs.unity3d.com/ScriptReference/Object.Destroy.html

[bold flare]

No-

I want to destroy it, but keep it destroyed when the game launches back

[latent latch]

So, are you asking how to serialize a game object without specific components

[bold flare]

For exemple, let's say I have a "tutorial" gameobject. When the tutorial is finished, I want to destroy it, and I don't want it to appear back when the game will be started a second time.

[scarlet viper]

  EditorApplication.playModeStateChanged 

anything that executes after i click Play but before the game launches ?

This one executes after game launches

[bold flare]

I suppose I know how to do it, but I would like to hear your proposition, yes. Same for script attached on a gameobject that I no longer want to be attached to this gameobject.

[heady iris]

You can't modify the scene in a built game.

What you can do is immediately destroy the component upon loading the scene

or, perhaps, choose not to create the component at all

so rather than having to destroy a component in the scene, you simply choose not to create a component

[bold flare]

But I need it the first time the game is played, right? Am I doing the thing the wrong way?

[heady iris]

I don't know what your use case is.

[bold flare]

I gave an exemple here

[latent latch]

You'll have to flag it for when you deserialize the data you'll know not to create the GO with that specific component

[heady iris]

ah, I didn't read it, whoops

🫠

I would suggest having a component that checks if this is the first time you've played

[bold flare]

So, instead of creating the gameobject in the editor, and destroying it after game load if necessary, I should instantiate it with a prefab on game load, if I want to?

[heady iris]

If so, it spawns stuff to run the tutorial

right. that way, you don't have to deal with the tutorial components' Awake methods running

[swift comet]

It does have a state before it launches but make sure to check if(!BuildPipeline.isBuildingPlayer) to handle your case correctly as it also calls when building.

[bold flare]

(the tutorial was just an exemple, I won't check if it's the first time, but I understand correctly)
Thank you again, @latent latch and @heady iris. Your help is very appreciated!

[latent latch]

^^

[bold flare]

Uh-
Wait

Yeah, nvm, I just have to implement all the instantiating logic and conditions in my LoadingManager, I suppose. This seems a bit strange to me tho...

[heady iris]

no, you should just have a "tutorial spawner" component whose job is to check if the tutorial should be spawned

[bold flare]

So, for each script or gameobject I want to instantiate, I need to have another script on another gameobject that will do the spawn?

[heady iris]

Well, I would suggest just having one that handles everything.

It is the tutorial spawner. It spawns the tutorial.

Alternatively, you can leave the tutorial components and objects disabled, and then activate them if desired

[bold flare]

Mh... So, as we said, I should hard-code the conditions and logic to instantiate in a dedicated script. Alright, thanks again!

[scarlet viper]

it does seem to work thanks

[bold flare]

I'm absolutely sorry to follow up this conversation... There is so much things to instantiate, I'm sure there is a better way to do it... I mean, it can be some "interactor" script on all chests, killed bosses, destroyed rocks, picked up items... Do you imagine the number of lines of code I'll have to write each time a "permanently destroyable" object will be added to the game???

[heady iris]

okay, so now you're asking about a whole save-game system

that is a significantly harder problem

[wintry crescent]

Hi, I have a script that I'm using in the editor, to spawn copies of a prefab as childobjects. This happens outside of playmode
The script is attached to a gameobject
But I have a problem now - when I use this script to spawn a lot of objects, and I click on one of them in the scene view, the object gets selected in the hierarchy - but the hierarchy has, say, 300 objects now. And If I want to see the main root object that spawned all those objects, I have to scroll a lot and find it. I would like to make it easier to select the root object - is there something that could help me?
I cannot put it in a prefab (which would work as I'd like it to), because you cannot destroy gameobjects in prefab mode, as of 2021.3.20 at least

I'm specifically after the behaviour that happens when you have a prefab with multiple childobjects, and you click on one of them in the scene view - the prefab gets selected in hierarchy, instead of the childobject

[bold flare]

Again, the tutorial was just an exemple. Excuse me for the misunderstanding.

[tepid brook]

Hi guys i want to move a gameobject in an other gameobject but i want to keep the position.
when i move the object in the hierarchy its work but when i do it in script its not work someone can help me pls ?

[heady iris]

https://docs.unity3d.com/ScriptReference/Transform.SetParent.html

see the worldPositionStays overload

[tepid brook]

i've try with true and false and its same

[heady iris]

the entire point of worldPositionStays is that the world position stays

[bold flare]

Was thinking. I already have a save-game system. I just need to know a way to save the gameobject to destroy in a save file. Is [SerializeField] enough to get the gameobject on load?

[heady iris]

[SerializeField] just tells unity to serialize a field on an Object that would not otherwise be serialized

e.g. a private field

[tepid brook]

my object position is 0,65,0 when i move it in the gameobject with the hierarchy its -225, -895, 0 but he keep his position on the screen.
but if i setParent in script position is -940, -1245, 0 with false and if i put it to true its 0,65,0 but in the 2 case the object position is not the same as i do with the hierarchy x)

[heady iris]

if you're looking at the Transform component in the inspector, that shows local position/rotation/scale

[cunning pivot]

@leaden ice Look who i just found on them Unity forums hahaha

[leaden ice]

Not exactly a rare sighting 😉

[cunning pivot]

I see but for me it was lol

[swift falcon]

    private void Update()
    {
        TakeInput();
    }

    private void FixedUpdate()
    {      
        SetVelocity();
    }

    void SetVelocity()
    {
        rb.velocity = new Vector3(xInput, yInput, yInput);
    }

    void TakeInput()
    {
        xInput = Input.GetAxis("Horizontal") * speed * Time.fixedDeltaTime;
        yInput = Input.GetAxis("Vertical") * speed * Time.fixedDeltaTime;
    }

I dont think I ever used Velocity directly with input properly, is this good?

The speed looks consistent

[heady iris]

Sounds reasonable.

oh wait

why's fixedDeltaTime in there?

you're setting the velocity, not adding to the position

[swift falcon]

Yeah thats what i was looking it myself, should I just remove it and not use any times there?

[heady iris]

Your velocity should not depend on your framerate or the physics update rate

so, yes

[swift falcon]

alright

I just thought the input value would change quicker based on the framerate, but i dont know

[heady iris]

it's going to be a number between -1 and 1

[swift falcon]

yeah, wouldnt the number change quicker? but yes removing the time makes it good still

[heady iris]

that would be irrelevant

you just want the value

multiplying it by a constant wouldn't change how quickly the input changes

it'd just rescale the input

[swift falcon]

oh yeah

[heady iris]

if you want to make your velocity change non-instantaneously, then you'd need to do something in SetVelocity

[swift falcon]

Ive used GetAxis all the time but I still ask such goofy questions lol

[heady iris]

deltaTime doesn't cause stuff to change smoothly over time

it just converts "X per frame" into "X per second"

[bold flare]

So, we come back to my initial question: is there a value I can store in my save file and that let me find the gameobject on load

[heady iris]

you need a way to uniquely identify each game object

I'm not sure what the best way to do that in general is, sinec I haven't implemented that myself

I have done saving and loading based on ScriptableObject assets (e.g. I have an SO asset for each bonfire in my soulslike game)

in that case, I copied the asset GUID into the ScriptableObject

giving me a nice unique ID

[barren meadow]

i have a question

public bool BirdIsAlive = true;

this is in one script called LogicScript, and in another script called BirdScript there is a function that requires this variable

    if (Input.GetKeyDown(KeyCode.Space) && BirdIsAlive)
    {
        MyRigidbody.velocity = Vector2.up * FlapStrength;
    };

question is: how do i get the value of BirdIsAlive from LogicScript to BirdScript?

[thin aurora]

Depends on in the scripts are related and/or how many instances exist of the logicscript

Do they have something in common like a manager that spawns them?

Are there multiple logicscript scripts?

Do they exist in the editor or instantiated later?

[floral fractal]

is there any methods from System.IO or AssetDatabase or Resources basically whatever, that can get the amount of file on spesific folder, Like
Resources.LoadAll or AssetDatabase.LoadAllAssetAtPath are returning array of something, and i can do arr.Length to get how many item present, but i dont want to load that, i just want to know how many item there, thanks

[dim whale]

System.IO.Directory.GetFiles("path").Length

That said, System.IO will find all files, including meta files.
AssetDatabase filters objects related to the project

There is also AssetDatabase.FindAssets() that uses the same search filter as in the Editor Project View

and can search in specific folders

[barren meadow]

its just one script of each, and they are in two different objects on the same scene, LogicManager and Bird respectively, and they are there from the start not spawned or instantiated later

[thin aurora]

I would say add a SerializeField on the bird and assign logicmanager on it

[barren meadow]

ok let me try that

[tepid brook]

Can someone help me to change the parent of an object and keep its position like in the hierarchy ?

[barren meadow]

lets goooo it worked

[heady iris]

.

the local position, rotation, and scale will change when you call SetParent with worldPositionStays=true

[tepid brook]

i know but that not help me

[heady iris]

that is expected

If you're parenting it to a non-uniformly-scaled parent, then that could cause distortions

[tepid brook]

my problem is the position not the scale

when i drag my gameobject to the parent in the hierarchy its work

[heady iris]

perhaps you can show what's happening

[tepid brook]

sure

[floral fractal]

thanks, i will try it

[tepid brook]

So i create a line beetween 2 circle in the left side this is my gameobject position when it spawn, and on the right this is the position when i move in Hierarchy.
its perfect that what i want but i need to do that witch a script and when i do it in script the position is not the same and my line is out of screen do you underrstand what i want to do ?

[heady iris]

seems like a z-fighting issue

[tepid brook]

so what i need to do ?

And when i setParent in script this is the position of the gameobject (out of screen)

i don't know how the position is calculated when we move the gameobject in hierarchy but i want the same in script x)

[heady iris]

oh, these are UI elements

with rect transforms

are you sure you're getting an identical hierarchy layout

[tepid brook]

i don't know what is this sorry

[heady iris]

this is a UI

Children render in front of parents

and later siblings render in front of earlier siblings

Look at how the three objects -- the two circles and the dashed line -- are positioned in the hierarchy

[tepid brook]

this is my hierarchy and the line spawn on RoomMap and setParent to MapImage

[heady iris]

and is that exactly how it looks when you do it via SetParent?

[tepid brook]

yes

[heady iris]

wait, you say that you're spawning it, then setting its parent

won't it spawn at some random position you don't want?

[tepid brook]

Yes i spawn it in RoomMap and set the localPostion to (0,65,0) and setParent to MapImage

[heady iris]

set the local position after setting its parent

it's called worldPositionStays, not localPositionStays

[tepid brook]

Room parent or MapImage parent ?

[heady iris]

what are you spawning?

set its local position after setting its parent

[tepid brook]

This is my code

_first = RoomMap gameobject

[heady iris]

so yes, set the local position after parenting the transform

local position is your position relative to your parent

[swift falcon]

sorry if wrong channel, but what the hell is this?? its not letting me build my game.

playmode works okay, then i try to build for android il2cpp, it shows those two errors, and playmode stops working

[somber wraith]

Weird.

[swift falcon]

2021.3.22f1

[leaden solstice]

It says your script has error

[swift falcon]

those two errors

[leaden solstice]

Does it have any other log when you click it

[swift falcon]

nope

[leaden solstice]

Just empty?

[swift falcon]

theyre just there, i click, double click, right click, nothing

yes two empty errors

it also asks if i want to go to safe mode when i open the project

[heady iris]

that means you have compile errors.

[leaden solstice]

Try safe mode

[swift falcon]

it goes into playmode successfully

[heady iris]

see what is being reported.

[swift falcon]

dont know if this fits the topic, but i dont have roslyn and unity_csc.bat* in my unity tools folder

[leaden solstice]

In Unity installation?

You don’t have compilers? That sounds little unlikely

[swift falcon]

C:\Program Files\Unity\Hub\Editor\2021.3.22f1\Editor\Data\Tools

no unity_csc.bat

[leaden solstice]

But probably worth trying reinstalling Unity

[swift falcon]

and no "roslyn" folder with csc.exe

its a clean installation but ill try anyways

also on project load sometimes it shows 'the file memorystream is corrupted remove it and launch unity again [position out of bounds!]' and only opens after trying again

[heady iris]

a new installation, perhaps

but not a clean one

[swift falcon]

yeah i just installed it

[leaden solstice]

Sounds like bunch of issue going on

Reinstall & Reimport all & Pray

[swift falcon]

also is InputShutdown supposed to take 3 years to complete when im trying to close unity?

oh hey new errors

[empty hollow]

Hello, I'm using the interfaces IPointerEnterHandler, IPointerExitHandler in some script but when building for mobile it gives me warning.

Game scripts or other custom code contains OnMouse_ event handlers. Presence of such handlers might impact performance on handheld devices.

However, if I put the interface implementation in conditions (#IF_STANDALONE..), it then says that interfaces are not implemented when I switch to mobile platform.

Any way of solving this ?

[leaden solstice]

Cool it has some text at least

[swift falcon]

yeahh but still dont make sense to me

[leaden solstice]

I think you should try different machine

And see if it is reproducible

[swift falcon]

you mean use another computer and build it there?

[leaden solstice]

Yeah

[swift falcon]

i think a vm will work

[leaden solstice]

Probably

[leaden solstice]

You can #if the interface list 😄
