[winged tiger]

and the MoveTowards returns:

oh

[mystic yoke]

Post full current code please. You're just trying to get it to move in and out locally, right?

[winged tiger]

yes

Vector3 dest_position;
    void UpdatePos()
    {
        float map = mapfloat(progress, 0, 1, 0, 0.016773f);
        dest_position = Vector3.MoveTowards(transform.localPosition, new Vector3(start_pos.x, start_pos.y, start_pos.z + map), 1);
        // transform.Translate(dest_position - transform.localPosition);
        transform.localPosition = dest_position;


        if (debug)
        {
            print(dest_position);
            DrawHelperAtCenter(this.transform.forward, Color.blue, 0.5f);
        }
    }

that's the important code

[knotty sun]

this

dest_position = dest_position - transform.localPosition;

should be

dest_position = transform.localPosition - dest_position;

[winged tiger]

still shoots out to infinity

[knotty sun]

because you want to move the difference between where it is now and where you want it to be

[winged tiger]

and that

kinda works but

[mystic yoke]

What is mapfloat

[winged tiger]

 float mapfloat(float value, float from1, float to1, float from2, float to2)
{
    return (value - from1) / (to1 - from1) * (to2 - from2) + from2;
}

this function maps a float

it works as expected and returns correct values

[mystic yoke]

Ok lemme write something up

[winged tiger]

okay

[mystic yoke]

I'm on a phone so give me a bit

[knotty sun]

are you reseting start_pos every frame?

[winged tiger]

wow coding on a phone

[winged tiger]

no

[mystic yoke]

Yah not ideal lol

[winged tiger]

void Start()
{
    start_pos = this.transform.localPosition;
    if(debug) print(this.name+" : "+start_pos);
}

[knotty sun]

then your code is totally illogical

[winged tiger]

huh?

[mystic yoke]

What is progress? How does that get set

[winged tiger]

other script sets it

when I scroll up or down

it's clamped from 0 to 1

[mystic yoke]

var targetPos = start_pos + Vector.forward * progress * 0.016773f;

transform.localPosition = Vector3.MoveTowards( transform.localPosition, targetPos, 1);

Should do

[knotty sun]

look at what your code is doing, you are always moving away from where you started so, of course, it will eventually reach infinity

[mystic yoke]

Just make sure you're never resetting start_pos

[winged tiger]

it's still in the Start() function so sure

[winged tiger]

wait why Vector3.forward

oh

nvm

[mystic yoke]

Bc you're in local space

[winged tiger]

ohh

i forgot about that

still moving in the wrong direction

ah man I thought that was it

[mystic yoke]

Define wrong direction

[winged tiger]

you see that blue line coming out of the z arrow?

it should be moving in that direction

and int moved up on x

local

[winged tiger]

you can see that here

[winged tiger]

and I have no idea why that first one moved correctly

[mystic yoke]

I think it is time to check your assumptions. That code should work

[winged tiger]

yes

it should

[mystic yoke]

Are your screws in a parent go

Is your parent uniformly scaled

[winged tiger]

thats the parent

[mystic yoke]

What happens when you rotate the parent. Does it always move in the same global direction

Is your screw object split into a parent and child object, where the child has the graphics and parent has the logic?

[winged tiger]

the bolt is one object

that with the parent rotated

still same direction

[mystic yoke]

Global direction?

[winged tiger]

local

[mystic yoke]

Draw a ray for start_pos to target_pos

[winged tiger]

the bolt has Y rotation of 90

[winged tiger]

okay

[mystic yoke]

Then also run transform direction on that ray and draw that too

[winged tiger]

umm

that ray doesn't show up

[mystic yoke]

It's drawing at origin

[winged tiger]

the blue ray is transform.forward

[mystic yoke]

It's relative

[mystic yoke]

World origin

Add transform.position to it

[winged tiger]

to what

[mystic yoke]

I'm just running you through the debug steps I would do

[mystic yoke]

To start_pos and targetPos

[winged tiger]

??

[mystic yoke]

Interesting

Your screw is screwy

[winged tiger]

DD:

[mystic yoke]

Do you have local pivot turned on in the editor

[winged tiger]

yes

[mystic yoke]

Where is it on the screw

[mystic yoke]

Suspicious

What's the dotted line in blender

Screenshot of unity hierarchy of screw

[winged tiger]

it shows the object it's parented to

[mystic yoke]

Ok

[winged tiger]

now I'm just wondering, why transform.Translate moves the bolt correctly

like on the local correct z axis

[winged tiger]

my god

i changed Vector3.forward to transform.forward

and it works

shit

now if I unparent something it breaks

[mystic yoke]

Ok grab your bolt into a new scene

Or just put it at origin or something

Unparented

[winged tiger]

it works

no matter how the bolt is rotated

[mystic yoke]

Ok now put it under an empty, un rotated parent at origin

Use Vector3.forward in these tests btw

[winged tiger]

okay

[mystic yoke]

Ah I think I got the issue.

Try this:

var localForward = transform.localRotation * Vector3.forward;

And use that instead of Vector3.forward

[winged tiger]

I'll try

[sacred sleet]

so i have a piece of code that gets info from a google sheet but how do i set the value (I'm using CSV)

[winged tiger]

oh my

that

works

2 days of nonsense

constant suffering

for that small fix

[sacred sleet]

the code: https://hastebin.com/share/nabewisace.csharp

[mystic yoke]

I'm a bit rusty and also on a phone, sorry for the roundabout debugging

[winged tiger]

that's not an issue

thank you ❤️

[mystic yoke]

But! This is a good example of what you can also do when debugging. Break it down to component parts and test everything in pieces

Being able to solve your own problems is a wonderful skill when programming

[winged tiger]

yeah

true

I have time to acquire that skill

[mystic yoke]

Just takes practice

[winged tiger]

anyway

I'm just gonna go to sleep rn

thank you again for this life lesson

[mystic yoke]

Ciao

[winged tiger]

bye

[mystic ferry]

if I have several components that all implement IExample, and I want to modify the transforms of all IExample objects, how can I add all of those objects to a list/array to apply transformations to them? I thought I could use FindObjectsOfType<IExample> but that method apparently can't take interface type parameters

is the solution to just, not use a collection at all?

is that even possible?

[lean sail]

this should be relevant
https://answers.unity.com/questions/863509/how-can-i-find-all-objects-that-have-a-script-that.html

depending on where the components are, it might be better to do it another way. If its all children of an object for example there are different functions you can use

[mystic ferry]

thanks, exactly what I needed

[lean sail]

im pretty sure its not good performance, i just dont know much about your structure

probably fine for just getting something working though for the time being

[golden vessel]

Hey, I want to initialize an array, what am i doing wrong?

    public SetAndOpenMenuButton characterButton;
    public SetAndOpenMenuButton inputFightButton;
    public SetAndOpenMenuButton inputExploMenuButton;
    public SetAndOpenMenuButton logButton;
    public SetAndOpenMenuButton spellExploButton;
    public SetAndOpenMenuButton[] setAndOpenMenuButtons = new SetAndOpenMenuButton[6] { settingsButton, characterButton, inputFightButton, inputExploMenuButton, logButton, spellExploButton };```

[lean sail]

whats your error?

[golden vessel]

cs0236

Trying to find a translation

[lean sail]

can you show the actual error, im not a computer i dont know the codes

[golden vessel]

A field initializer cannot reference the non-static field, method, or property 'name'.

name being each of the SetAndOpenMenuButton

[lean sail]

when you googled that error, did you come across this link (which i assume your text is taken from)
https://learn.microsoft.com/en-us/dotnet/csharp/misc/cs0236

[golden vessel]

Yeah, i don't get it tho

Hooo then I just can't do it?

[lean sail]

your variables arent initialized

the example in the link shows you how to do it properly

[golden vessel]

Cos I define them in editor?

[mystic ferry]

they still have to be in a method body

[lean sail]

the editor is not related, you shouldnt assign these things outside of a function

[golden vessel]

I thought my problem was the initilization syntax

[mystic ferry]

#💻┃code-beginner

[golden vessel]

Okok ty

[teal silo]

So I understand it's not strictly programming, but can I ask a math/physics question here? I promise 100% it's related to programming lol

[potent sleet]

no

if it's general programming , not unity that is

[potent sleet]

just ask

[teal silo]

I'm making a small tower defense game where we have to use the kinematic formulas for calculating the projectile's movement. My team decided it would be cool if you could aim the projectile with the mouse cursor, so I found a good tutorial and adapted it to what we want. It works really well, but one of the requirements is that the player is able to set both the initial velocity and the angle. Is it possible for the player to set the initial velocity and angle when it is already known where the projectile is going to fall because of the aiming?

As I have it right now, the initial velocity needed to get to the point with the given angle is calculated for you. I haven't taken physics in ages and I've never been very good at them so I'm sorry if its a dumb question I'm just struggling a lot with this

[lament bloom]

I'm getting a null reference error that I can't find an explanation for. I'm not sure what change I made that caused this. I press play and I get an NRE directing me to a line in my PlayerController where I set an animator parameter. This suggests that playerAnim, the Animator component on the player, is null. But the player definitely has an Animator component as shown here. Furthermore, my attempt to verify in-code whether retrieving the Animator was successful isn't working, I added this debug statement, in the PlayerController's Start method, but it doesn't appear in my logs. Sorry for the image spam, just want to provide all the necessary context.

Worth noting: If i try to comment out the function that calls a method on the animator component, it finds another component to throw an NRE for, even though those other components definitely exist on the player as well.

[heady iris]

log it immediately before you use it

you might have an extra copy of the component lying around

[lament bloom]

this is weird

[steady moat]

If you set the initial velocity and angle, you will land on a given point. (Given that the acceleration is set)

So no, you cannot set the displacement, velocity, angle and acceleration.

[lament bloom]

logging is really just not working the way it should at all

[teal silo]

Thank you for confirming, that does make more sense. I was trying to figure out if there was any way that would be possible but it just didn't seem so.

[steady moat]

I'm not sure what you are expecting to happens.

You should challenge your team and see what is the true issue.

[steady moat]

Doesnt mean that the animation is never assigned ?

[lament bloom]

it is though, as evidenced by the odd debug statements

[steady moat]

I mean, you might want to debug that.

[lament bloom]

well

do you have a suggestion?

I've found that the animator exists/is not null, but I'm getting an NRE immediately afterward when I call a method on it

[steady moat]

Follow the function call and look why it is not reaching there ?

[heady iris]

eh?

[lament bloom]

if it was making it into the function call at all, the stack trace would show that

[teal silo]

oh no, it works perfecly as is right now. The player can set the desired angle and also aim with the cursor in a 3D terrain. We were just wondering if it's better to be able to set the initial velocity or to be able to aim the projectile, I guess. In my opinion, it's much more fun to be able to aim, so I think we'll just keep it that way. Thanks for the help

[lament bloom]

but the stack trace ends at this call, suggesting that this call is being made on a null reference

[steady moat]

My friend, can you share your whole code.

Instead of 2 lines.

[heady iris]

it seems pretty cut-and-dry

line 142: it does not equal null

line 143: null reference exception

[steady moat]

I see now. It is just there like 5 images.

[lament bloom]

if you'd like, https://hastebin.com/share/ezujomisex.csharp

not the cleanest though

[heady iris]

oh wait

I get it

notice how it's not logging "Object exists?"

you are doing

[lament bloom]

yes

[heady iris]

("Object exists?" + playerAnim) != null

[lament bloom]

ohh

thanks lets see

[heady iris]

operator precedence! addition beats comparison

and, since playerAnim is null, it becomes the empty string

[lament bloom]

Alright, confirmed that the animator does not exist

[heady iris]

wait, nvm, it doesn't show up at all :p

ye

[lament bloom]

then GetComponent isn't working for some reason

[heady iris]

that's much more sane

[mystic yoke]

Make sure the animator is on the object you're querying

[lament bloom]

yeah it is

[heady iris]

is this the right object, though?

[mystic yoke]

That doesn't mean that's the object you're querying

[lament bloom]

sure, let's log it real quick

[heady iris]

is the script attached to PlayerBody?

[steady moat]

Does rpgCharEvents = GetComponent<RPGCharacterAnimatorEvents>(); exists ? Otherwise playerAnim = GetComponent<Animator>(); will never be called.

[mystic yoke]

Oh, also you probably have multiple scripts in your scene running at the same time

So make sure you only have one playerbody

[lament bloom]

good point let's take a look

i think you're onto something, because that log statement in my start method isn't showing up

Ookay, yeah I see now, there's a much earlier NRE that only happens once, but as @steady moat figured out, it stops any further components from being retrieved. Thanks!

now to try and recall what i was doing before this mess

[mystic yoke]

Yah good tip when addressing errors: start at the top and work down

[lean sail]

Im unsure how I can implement additional logic for my character when some parts depend on it being a player or AI.

Character script, this is on a character. It takes character settings
https://paste.ofcode.org/3bwnccH7PMEm48CJWdDgdew

The character settings:
https://paste.ofcode.org/3aL62qJDaGXCCEhH9RRJSEy

Example input manager for the player
https://paste.ofcode.org/ETVf25aHXnVjTAeGyH28W2

I have the script CharacterMovement which applies these movements from Character. i cut out most code because the logic is not the issue.
https://paste.ofcode.org/c842JzcpqhDmPHWRUNecb9

My player moves in the direction of the camera, so i need a camera transform stored somewhere
The AI im making will walk to the player if the player is in range (or in a box collider)

With this design principle, how can I include a unique behavior in this script such as rotation, since the rotation depends on if the character is AI or player?

Should the camera/player reference be included in the characterSettings data and then ICharacterInput include a rotation method? What about the box collider on the AI

Most of the code is really small just because again the logic is not the issue, i have another test script where I do the player rotation properly. Its a matter of how should I get this working with a script that moves any character?

[mystic yoke]

You have the right idea separating out the input from the character controller. Store the camera info inside the player input and calculate camera relative input there, that gets passed to the generic character controller as pure worldspace input direction info. The AI player will pass world space input always

Basically, you're creating a translation scheme between specific control and generic control. Anything that is needed for generic control lives in the generic controller, and everything that's needed for specific control lives in specific controller, and the specific controller translates all of the specific control into variables the generic control understands.

For another example, if you wanted to add look direction to your controller, then look direction would be calculated by the camera in player controller, and the AI in the ai controller, and then passed to the generic controller as "look direction". The generic controller doesn't care how it gets calculated.

[lean sail]

I see, i guess the issue im facing was that the input manager for player or AI isnt directly on the character, so i cant just drag in the objects I need like camera transform or player transform

[mystic yoke]

By look direction I meant a visual head turning behaviour, btw. Realized that was unclear

[lean sail]

oh yea i understood

[mystic yoke]

So there's a couple ways to handle this

One is to make your player input and everything a monobehaviour component

[lean sail]

hm if its monobehaviour I can attach it to the player and then still insert that specific instance into character instead of a new ControllerInput() right?

that really does sound easiest if it works, since i can get component by script

[mystic yoke]

Correct, though it escapes me whether you can serialize abstract references in the inspector.

I think you can, but you'll have to try it out for me

If you want to drag it in the inspector that is

[lean sail]

yea i will, thanks a lot for helping

[mystic yoke]

Script assignments will work fine

[orchid surge]

I'm using the UniTask package (which works almost just like normal async await, but it respects timescale) and I'm hung up on a new issue. I'm gonna use a screenshot to describe the problem cause it will be a lot easier to follow than a set of pastebin links.

Lines show how the methods are supposed to be called. For some reason it reaches 40| Debug.Log("fireasync"); in the middle, but then it just sits at 41| pattern.ShootPatternAsync(....) until I stop the game. There is no loop to get stuck in. Can anyone tell what's going wrong?

[orchid surge]

You can do this, assuming I understand what you mean.

[mystic yoke]

Cool, thanks for confirming

It's been a minute since I've been in editor

[steady moat]

To serialize abstract reference, one most use [SerializeReference]. Alternatively, before [SerializeReference], we would use hidden MonoBehaviour.

[mystic yoke]

I was talking specifically about an abstract monobehaviour

What do you mean by hidden monobehaviour?

[lean sail]

how many tasks are there? is it possible numSteps is 0? The only thing i can see is that maybe u need to return a completed task inside ShootPatternAsync but its been awhile since ive worked with this stuff

[stark fiber]

Hey guys, in a 2D game, how do you control how your sprite appear vs stuff in the Canvas?
I tried sorting layers, didn't do anything, I tried moving the hierarchy around, didn't do it, I tried moving the Z position, didn't do it.

In my canvas there's an image and this image will always be on top of anything outside of the canvas

[orchid surge]

I'm not sure how to check the number of tasks, but if I try to shoot the pattern 5 times, then I get 5 errors when I stop the game. There are two other implementations of the shot pattern that don't have any awaits in them, and they got compiler errors until I made them return completed unitasks. The one that does have awaits will error if I try to return a completed unitask in it. None of them work.

[potent sleet]

did you put the Canvas in ScreenSpace - Camera

sort order should work by then

[leaden ice]

If you're using a Screen Space - Overlay canvas, yes the canvas will appear on top of everything else.
If you make your canvas Screen Space - Camera, you can put things closer than the canvas plane distance and it will show in front of it

[lean sail]

you could check the number of tasks just from the list, before you use WhenAll(tasks)
If you add a debug as the first line in ShootPatternAsync does that ever print?
One other issue could be if you are trying to await the same task twice

like if _fireables somehow has a duplicated entry

I dont know what else would cause this issue, the "return a completed task" suggestion assumed ShootPatternAsync actually runs but I see thats likely not happening

[stark fiber]

Thanks a bunch to you two, that indeed was the problem!

[leaden ice]

One possibility is you have an exception being thrown somewhere in your task(s)

[lean sail]

o i cant believe i forgot to suggest that possibility, I even saw that on the UniTask docs

[mild wolf]

Does anyone know how I can go about manually selecting the device I want from my devices list in the new input system when I have multiplayer local coop? Can't find any documentation on it

[leaden ice]

But what device would you use to select the device 😮

[molten thicket]

Hey Team,

So I just had a first with Unity,

Windows 11 using 2021.3.8f1 & 2021.3.22

My build runs fine in the editor, but when I build and run for windows, it will go to the splash and then just crash.

Are there logs anywhere I can look into?

[potent sleet]

PlayerLogs or CrashFile

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

[orchid surge]

That was it.

[molten thicket]

Thank you!

I assume this is bad xD

[potent sleet]

Yeah there is literally a site name after it xD

[blazing smelt]

When you're making an interactable object that uses UnityEngine.EventSystems interfaces (e.g. IDragHandler), how does it quantify what the selectable area is for the object? I've gathered it works off the renderer rather than any collider, but I'm still unclear on if it selects a specific collider or somehow aggregates all the children that have renderers.
Does this question make any sense?

[potent sleet]

goes by the boundaries iirc

like the gray boundary you see with rect tool

iirc it also includes the children rects

[blazing smelt]

gotcha. Curious if there's a way to see that boundary in the inspector, for 3D objects rather than just UI elements

[potent sleet]

yes, like I said use the Rect Tool

[blazing smelt]

oh right you edited it

cheers thanks

probably generates those rects using the renderer's bounds struct

hm I'll have to check the layers because I realised there was already a visible collider as a child of the script, that didn't seem to trigger the event

[potent sleet]

you have collider on UI element ?

im a bit confused

[visual fractal]

Why is scene management so confusing? I've figured out a way to transition from the start menu to the game. The SceneManagement.GetSceneByName() Is supposed to have a string argument, right?

So why does it not accept a string as the argument?

[wide terrace]

but it does?

[visual fractal]

Not for me.

[buoyant crane]

Manager or Management?

[visual fractal]

Unless my code is wrong? SceneManager.LoadScene(SceneManager.GetSceneByName("MainLevel"));

(SceneManager.GetSceneByName("MainLevel")); is underlined in red.

[buoyant crane]

what’s the error?

[visual fractal]

Argument 1: cannot convert from 'UnityEngine.SceneManagement.Scene' to 'string'.

I looked on that unity webpage Null loves sending to people, but it doesn't really help.

[buoyant crane]

LoadScene takes either the scene’s index or scene’s name

it doesn’t take an actual Scene

[visual fractal]

How do I find the scene's index or name?

[lean sail]

with your error, its telling that you that LoadScene was expecting a string but you provided it a UnityEngine.SceneManagement.Scene

[buoyant crane]

LoadScene("Main Level"); or LoadScene(0) depending on its build index

[lean sail]

you have its name in your function

[visual fractal]

Ah. OK.

[buoyant crane]

you already have all the info

[visual fractal]

Ah. That worked. thanks.

[lean sail]

When looking at errors, make sure u try to understand what its really telling you as well. If its cannot convert X to Y, that means the type is Y and it wants Y somewhere but you gave X

[potent sleet]

if you're confused always look at !api

[tawny elk]

[blazing smelt]

don't know why, I didn't make the prefab but now I'm tasked with working on it

@potent sleet also it's a world space object

but the collider still doesn't seem to do anything

[potent sleet]

UI element should not have collider

do you have an Image component on this world space canvas ?

or is it spriterenderer

[blazing smelt]

A couple of MeshRenderers. It still works but I was trying to make sure I understood exactly how, since I'll need to make some new code that edits the values in runtime.

I need to set up the renderers so they're invisible but still register the drag indicator

Could anyone point me into a direction to find how to implement mathematical formulas into code. Where would I learn how to practicality implement formulas into actual projects.

Hello. I am making an online card game using Netcode for Game Objects. Right now I am spawning the cards in the hand serverside, and I have logic for the player to drag-and-drop cards onto the table. However I am running into all sorts of error with desyncing networkobject or networkbehaviour states, I think because fundamentally I am moving cards client-side but not sending that serverside even though the server owns the cards. Right now I have an event that triggers when the player chooses to play the card, and that trigger is what causes the errors.

My question is, what is a good design or best practice for netcode for a card game? If I could look at example written in Netcode for Game Objects it would really help.

I have a HUD which displays the lives. I have one life in the editor and try to introduce new life UI elements when the following function is called (see screenshot)

public void SetAmountOfLives(int amountOfLives) 
    {
        // ...
        float objWidth = lifeRect.rect.width / 2;
        
        for (int i = 0; i < amountOfLives; ++i) 
        {
            GameObject obj = Instantiate(_LifeObj, _panelObj.transform);
            RectTransform objRect = obj.GetComponent<RectTransform>();
            objRect.position = lifeRect.position + new Vector3((-amountOfLives / 2 * objWidth) + i * objWidth + (amountOfLives % 2 == 0 ? objWidth / 2.0f : 0), 0, 0);
            _lifeObjList.Add(obj);
        }
        //...
    }

The issue is that at different resolutions, the space between the hearts changes for some reason. Any way to fix this?

[soft shard]

Have you setup anchors for that element? If your Canvas is on a set resolution with a Canvas Scaler component, and your anchors for those elements are setup for the location and space on screen they should try to occupy, then the whole canvas should scale with resolution

[wise arch]

Does that answer your question?

My artist did a lot of the UI

I am just the programmer trying to fix it

xD

[soft shard]

That looks like its using default values, what is your "Health" container using? The docs may help for understanding anchors better as well: https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/UIBasicLayout.html

Why am I getting this error message "NullReferenceException: Object reference not set to an instance of an object", my script is working correctly.

[RequireComponent(typeof(AudioSource))]
public class BallAudioController : MonoBehaviour
{
    [SerializeField] private AudioClip bounceClip;
    [SerializeField][Range(0, 2)] private float minPitch = 0.8f;
    [SerializeField][Range(0, 2)] private float maxPitch = 1.2f;
    [SerializeField] private float minVelocityMagnitude = 0.5f;
    [SerializeField] private float maxVelocityMagnitude = 5f;
    [SerializeField][Range(0, 1)] private float minVolume = 0.2f;
    [SerializeField][Range(0, 1)] private float maxVolume = 1f;

    private AudioSource audioSource;
    private Rigidbody ballRigidbody;


    private void Start()
    {
        audioSource = GetComponent<AudioSource>();
        ballRigidbody = GetComponent<Rigidbody>();
        if (audioSource == null)
        {
            audioSource = gameObject.AddComponent<AudioSource>();
        }
    }

    private void OnCollisionEnter(Collision collision)

    private float Remap(float value, float from1, float to1, float from2, float to2)
    {
        return (value - from1) / (to1 - from1) * (to2 - from2) + from2;
    }
}```

[wise arch]

can you mark line 34?

in your script

[wise arch]

audioSource is likely to be a nullptr which means it isn't assigned

Your script likely stopped working at that point

if it still works, try to clear errors and check if it appears again. If it does, make sure you are looking at all instances of the script

[verbal urchin]

Yeah, it's working but gives the error message. I have just one instance of the script in the game. Should the audiosource component have some sound assigned to it or something? I'm currently assigning the sounds directly in the script.

[wise arch]

Audio clip is set to none, which is probably the source oif the issue

[ashen gyro]

The Start() assigns it even if it's null by adding the component

[soft shard]

If that text object that seems to be holding your hearts doesnt already, you could try adding a horizontal layout group, then it can control the spacing of each element for you, otherwise, I would maybe make a new empty rect transform and set its width to what you want it to be, then set its anchors to match, and make your heats a child of that object

[verbal urchin]

Didn't help adding an audioclip there.

[wise arch]

Adding horizontal layout to the parent of the hearts?

[ashen gyro]

The collision event can fire before the start() fires potentially?

[wise arch]

Impossible

[ashen gyro]

Try making the audioSource variable public and assigning it in the inspector

[wise arch]

Don't, use [SerializeField] instead of makign it public

[vague slate]

how ParticleSystem counts particles when it has child systems?
For example if there a hierarchy and I want to modify all particles directly through GetParticles(array) SetParticles(array)
Do I need to go through each particle system or only root one?

[verbal urchin]

Thanks! That solved it (though I used serializefield like wardergrip suggested)

[ashen gyro]

Sounds like it was indeed firing the collision before the Start() had assigned/created it properly

[wise arch]

Okay, in hindsight, perhaps making the component is a delayed execution https://docs.unity3d.com/Manual/ExecutionOrder.html

[wise arch]

To clarify, public allows any class to access that variable and do whatever they want with it (unsafe)
private makes that access only to your class, [SerializeField] allows you to change it in inspector

[soft shard]

Yeah, to the parent of the hearts, the layout groups will reposition the child objects (and overwrite any position changes while its enabled)

[wise arch]

any way to make it appear under the text?

You can format your multiline code block with C# highlighting! Just add cs to the start of it. Highlighting example below!

[ashen gyro]

Reason I asked here as it's not directly related to the networking, but in general that a field from an object can be printed out correctly, but then be written to a stream as 0 in the same function scope

Actually, I should also just dump the bytes received on the server's end and just hexview it

[soft shard]

You could move it below, and set the anchors to stretch/span the full width or be specifically positioned to the bottom of it

[wise arch]

I can't change the position of the heart

[soft shard]

Then you would change it through the layout component on your parent

[wise arch]

okay just saw there is a little menu for padding but it was collapsed

thanks!

My hearts still overlap in full hd and overlap more the higher res I go

[wise arch]

Did I forget something or is there a different way?

[soft shard]

Do you have a Canvas Scaler setup on your Canvas?

[ashen gyro]

nvm I'm an idiot, of course it doesn't save my value if it writes to the stream before I change the value

[swift falcon]

for some reason my clamp teleports camera rotation, and teleports only when im moving my mouse left

and i cant find where exactly i make a mistake

[wise arch]

Yeah, I think it is setup well

[soft shard]

Looks fine to me, if the layout is attached to your text, maybe try a empty transform instead to put the hearts in and have that as a child of your text

[iron quiver]

Hi! I am trying to layer different settings on top of each other but for some reason I am not able to change any settings in my inspector. Can someone help me out?
its split in different scripts but this is the base settings:
`using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class NoiseSettings
{
public float amplitude = 1;
public float frequency = 2;
public Vector3 position;
[Range(1,10)]
public int numLayers = 1;
public float persistence = .5f;
public float baseFrequency = 1;
public float minValue;
}`

this is where the settings will be called:
`NoiseSettings settings;

public generateNoise(NoiseSettings settings){
    this.settings = settings;
}`

and here is where the array should be loaded:
`ShapeSettings settings;
generateNoise[] generateNoises;

public ShapeGenerator(ShapeSettings settings){
    this.settings = settings;
    generateNoises = new generateNoise[settings.noiseLayers.Length];
    for (int i = 0; i < generateNoises.Length; i++){
        generateNoises[i] = new generateNoise(settings.noiseLayers[i].noiseSettings);
    }
}`

For reference: I am a coding noob. And this mostly consists of a tutorial: https://www.youtube.com/watch?v=uY9PAcNMu8s

[iron quiver]

there is something missing, here is the code where I say that I want this as an array:
`using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[CreateAssetMenu()]
public class ShapeSettings : ScriptableObject
{
public float radius = 1;
public NoiseLayer[] noiseLayers;

[System.Serializable]
public class NoiseLayer
{
public bool enabled = true;
public NoiseSettings noiseSettings;
}
}`

[sand ridge]

Moving my question here as it seems this is more general and not beginner:

I'm trying to create a custom menu by overwriting bits of the IMGUI. The first part is to simply implement a background image to a box control:

boxTexture = ResourceUtils.LoadTexture(ResourceUtils.GetEmbeddedResource("Resources.background.png", null));
boxStyle = new GUIStyle(GUI.skin.box);
boxStyle.normal.background = boxTexture;

This works as expected. However, something seems to affect the brightness of the image or menu when called within the game. I thought this might be GUI.color, GUI.backgroundColor and / or GUI.contentColor. So I tried several ways of changing those to color with 0 alpha (resulting in invisible menu), color with 1 alpha (resulting in color overwriting background image completely) and Color.clear also resulting in invisible menu.

My question is: How do I stop IMGUI "somehow" affecting the background image? See screenshot attached to this message.

[woeful dagger]

hello i have a question

how to transfer the camera through a webservice. Do I have to go through a render texture?

or directly via the camera trying to have in both cases an array of bytes

[finite hazel]

you mean unity? or some package?

[woeful dagger]

no body can help me?

[thin aurora]

What do you mean with webservice?

[woeful dagger]

who cares what will become of me what worries me is how to convert (camera -> to array bytes) or (renderTexture to -> array bytes)

[dusk apex]

If you're just trying to convert an object to bytes.. Google would yield you immediate results.. example https://stackoverflow.com/a/10502856.

[woeful dagger]

I'm going to try that I didn't think about it at all, really not stupid and I'm rebuilding on the other side

thanks

[dusk apex]

Reminder that object references/address and ids will be different on both ends.

[slow jewel]

I have a save and load script that makes a file using application.persistantdatapath but when I export it to universal windows platform it only works for the pc version but not the xbox

[knotty sun]

if you are going via web best option is RenderTexture->Byte[]->Base64 string

[warm stratus]

hey, these 2 lignes doesn t turn the object around the same axis, and i wan t to make the second ligne has the same axis as the first

transform.localRotation = newRotation;
gameObject.GetComponent<Rigidbody>().MoveRotation(newRotation);

[woeful dagger]

i try with that code

and

[knotty sun]

Not a good plan, how do you expect what's on the other side to understand the output from BinaryFormatter?

[sacred dove]

Hi! Why can a callback from .jslib not be called?
I've put it in Assets/Plugins folder, and it is called when needed (there is console.log), but there is no callback

Either way. I've seen these type of games pop up in TikTok streams to often 😄

[woeful dagger]

public static Object ByteArrayToObject(byte[] arrBytes)

memStream.Seek(0, SeekOrigin.Begin);
var obj = binForm.Deserialize(memStream);
return obj;
}
}

[knotty sun]

ok, so you need your receiving code to take the Base64 string from the web and convert it back to a byte[]

problem is, with your setup, you will end up with a RenderTexture object which you will not be able to use. you need to send the contents of the RenderTexture

well, what is the console telling you?

[heady iris]

remove the quotes

[heady iris]

you put in the actual class there

[patent wadi]

oh...

[patent wadi]

class?

[heady iris]

literally just remove the quotes

UniversalRenderPipeline

typeof takes that identifier and turns it into a piece of data that the annotation needs

[patent wadi]

ooooh... i understood now

[patent wadi]

the class..... like DottedBloomEffect?

[heady iris]

no, UniversalRenderPipeline

[patent wadi]

oh got it

no i was talking about the second error

[patent wadi]

dis one 😅

[heady iris]

well, look at your spelling

you can't just randomly change the capitalization and expect it to work

the IDE's suggested auto-fix for the interface problem should create two methods

(including the override keyword in their declarations)

[patent wadi]

this is the "potential fix"

[heady iris]

there are two potential fixes

it looks like the second option is the one that explicitly names the interface that we're implementing the functions for

I'd go with the first one.

[patent wadi]

this is the first one

[heady iris]

oh right, brain fart

you wouldn't use override here

anyway, yes, that looks reasonable

notice how the capitalization is different..

[patent wadi]

this solved my problem

[heady iris]

i usually just let the IDE generate the methods and then fill them out myself

[patent wadi]

i did not capitalize my I's

cool

thanks

[plain coyote]

In unity, I am trying to read pixel values from a texture,
but it seems like the pixel values are wrong?
specially compared to the same file being read using
Bitmap API in System.Drawing

here is how I read both:

Texture2D tex = null;
        byte[] fileData = File.ReadAllBytes(img2Path);
        tex = new Texture2D(640, 640,TextureFormat.RGB24, false);
        tex.LoadImage(fileData); //..this will auto-resize the texture dimensions.
        tex.Apply();

and then to read pixels
I do:
tex.GetPixel(x,y);

I compared the first few pixels, with the first few pixels from the
Bitmap image, and it was very different.
any ideas?

        using var image = Image.FromFile(img2Path);
        Bitmap bitmap = image as Bitmap ?? new Bitmap(image)
        BitmapData bitmapData;
            if (bitmap.PixelFormat == PixelFormat.Format24bppRgb && bitmap.Width % 4 == 0)
            {
                bitmapData = bitmap.LockBits(rectangle, ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb);

                unsafe
                {
                    data = new Span<byte>((void*)bitmapData.Scan0, bitmapData.Height * bitmapData.Stride);
                }
            }

then I do read values from the data
as follows:
data[0] = b
data[1] = g
data[2] = r
and so on,
the values for
Bitmap are:
0.3 031, 0.32
but for the texture they are very different. (0.008, 0.023, 0.31)

[woeful dagger]

how i keep the texture of camera without put a rendertexture? a i can screenshoot ( it's good or bad idea)?

[ashen yoke]

visually do you see a difference?

[plain coyote]

I believe it has to do with sRGB but that is my only hint

[plain coyote]

the colors yes, but when I render or save the image it does not seem much different (There is some differences definitely in the Yellow component, but the output image is definitely acceptable)

[plain coyote]

I heard somewhere unity Does sRGB by default, is there some where to turn this off, just to be sure I am not doing anything weird?

[ashen yoke]

there was some conversion util somewhere in unity internals, and its a common pain point

i cant recall solution but there are various problems related to linear/gamma

[plain coyote]

if it is a bit of different implementation I don't mind it honestly, like I don't care much about 0.31 vs 0.32 or so, but I definitely care if it is doing 0.32 vs 0.008

[ashen yoke]

if they visually look the same, its weird, maybe the corners are different?

coords origin

[plain coyote]

not exactly the same, as I mentioned it is a bit different,
but I need it in RGB space, because I want to do ML detection on it. (and the model was trained on RGB)

[ashen yoke]

that is too much of a discrepancy imo

[plain coyote]

what do you mean?

[ashen yoke]

orders of magnitude difference, i dont think sRGB can account for that

[icy inlet]

Hello i'm all new to this but i need to think of a login system for a software wich has an already build api and database, i want to do a login with discord but i have no idea how hard or even if it's possible

[plain coyote]

I am a bit lost, I thought (and sorry if I misunderstood you) you agreed than the difference is probably gamma correction?
so what I asked was how to turn it off.
or did you mean something

[ashen yoke]

#archived-code-general message

i.e. Bitmap starts at top left and unity at bot left

[plain coyote]

yeah I saw your message, but I don't think it is?
well, I checked only the bottom and top corners,

I will check the other two, but it is a bit unlikely I think.

[ashen yoke]

ah you had different order there missed that

yeah now srgb seems more realistic

[plain coyote]

disabled sRGB for the entire project, and that definitely was it,
the model seems to be working now.

is there a way to disable it on a texture basis? because I don't want to keep my sRGB disabled. (Tho this might not matter in the end, as I can write a converter back later on, but will help me significantly in my debugging process right now)

[ashen yoke]

probably yes, the flag is available in the importer, maybe there is an arg in load bytes somewhere

[plain coyote]

I will look into textureImporter (whichp popped in google but hoped there was something just like:
sRGB = off:
sRGB = on;

Thanks!

[ashen yoke]

importer is editor only

[plain coyote]

oh, that is why I was struggling to get something from it... that is useless because in the end I would want to get them from camera feed.

[hot torrent]

How resource intensive is it to call a SphereCast every frame for a couple of seconds?!

[ashen yoke]

i mean that there is a lot of editor things of which you only get scraps at runtime, i would first apart from googling read through all the overrides for all texture byte loading methods

there is also i think something like EncodePNG maybe it has decode and i think there was some static util available for this

ImageConversion class has a bunch

EnableLegacyPngGammaRuntimeLoadBehavior

may be useful

[ashen yoke]

a non alloc version should be fast

[hot torrent]

what does a non-alloc version mean?

[ashen yoke]

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

non alloc means non allocating

meaning it doesnt allocate new array to store results every time it is called

you create an array/list and provide it to the method

[hot torrent]

mhm...

so what can't i do with this sphere cast, that i could do with a normal sphere cast?

[ashen yoke]

it should be identical apart from non alloc part

most casts/overlaps have non alloc versions

[hot torrent]

aha, got it!

thanks!

[uneven monolith]

Hey umm so i have grid system setup and I want a mechanic to know which tiles player is able to 'see', even tight angles count.(here is some drawnings to visualize the idea).

What would be easiest way to approach this. Its not like i couldnt do some kind of raycasts, but i have to get every tile in the way before wall+i would need to cast like 100 of them to different direction for being able to be precise enough.

So I just thought if there is some good solutions/methods for this kind of stuff already so i dont have to think with my own brains lmao.

Also player is always centered in some tile so casts are sent from a middle of that tile, so like u cant be inbetween of few tiles

(And also i dont know if mathematically that bottom right corner should be seen from there, just tried to show example that i want it to also spot rly small gaps and see throught them)(propably not tbh)

[heady iris]

Do you only care about seeing other entities?

Or do you need to do some kind of fog-of-war system?

[uneven monolith]

Fog of war

[heady iris]

I'd start with raycasts

[uneven monolith]

Yeah, propably the best option

[latent latch]

since you're using a grid might as well do it the mathy way

[nova bramble]

I've been having issues getting a WebGl build of my project working on unity play. The screen looks like this and dosent load in the game and returns this message in the console.

im assuming its because of the memory leak

but i cant figure out for the life of me how to get rid of it

I tried

looking it up and install a new package to trace the leaks but i dont know where to go from there

[simple egret]

First things first, make sure it's the actual issue. Open your browser's dev tools window and reload the page, watch for errors

Also it's probably not a code issue and better asked to the experts in #🌐┃web

[mystic ferry]

for an inventory system, I've seen people make every inventory cell a button, and I've also seen people just make them containers with an image component. Are there any unforseen upsides or downsides to either of these approaches? just wondering if one is "better" for any particular reason

[latent latch]

Both sound like similar approaches

[leaden ice]

A Button is little more than a Selectable with a UnityEvent for the PointerClick event

It kinda just depends what kind of functionality you need on the inventory slots

[mystic ferry]

could you elaborate? I genuinely thought that was all they were haha

[leaden ice]

Elaborate on what

[mystic ferry]

how buttons are more than a selectable with a unityevent

[leaden ice]

I said little more

as in, that's basically all they are

[mystic ferry]

ohhh

my bad

[warm shadow]

So I have a function that needs to find every tile in a grid array that is Null, but the grid array is 2d, so I can't use Find, how do I do it?

foreach (Tile tile in Array.FindAll<Tile>(grid, tile => tile != null))
{
    //Do something
}

[leaden ice]

for (int i = 0; i < grid.GetLength(0); i++) {
  for (int j = 0; j < grid.GetLength(1); j++) {
    if (grid[i, j] == null) {
      // do something
    }
  }
}```

[warm shadow]

ahh, I see, that makes sence, thanks

[simple egret]

Or, keep the foreach which will flatten the array and check each element for null like above.

foreach (Tile tile in grid)
{
    if (tile != null)
      // code
}

[leaden ice]

problem with foreach is it's harder to then do something like grid[i, j] = something;

but it depends if you need that or not

or to access the i, j

[warm shadow]

yes, I do actually need the i and j, just forgot

[brittle nebula]

Hello does the Physics.Raycast method work by simply doing a ray triangle intersection test of every triangle in the scene?? or how does that shit work

[leaden ice]

No - first off it will do broadphase collision tests against the collider bounds using the spatial partitioning structure of the physics scene

that narrows down which colliders it needs to test

then it takes that smaller subset of colliders and tests each one individually - but the algorithm for each depends on what kind of collider it is

SphereColliders and capsule colliders don't even have triangles for example

[brittle nebula]

makes sense

but with a mesh collider it would need to make ray triangle intersection tests tho right?

[simple egret]

Spheres would just check if the intersection is in their radius, IIRC

[hexed pecan]

It also checks the AABB before checking any individual triangles when it comes to MeshCollider

[leaden ice]

Possibly? Not really sure how PhysX implements it. The code is open source though

This seems relevant:
https://github.com/NVIDIAGameWorks/PhysX/tree/4.1/physx/source/geomutils/src/intersection

[fluid lily]

I have a UnityEvent<object> variable, and I am setting a method call for it in the editor MyClass.SetEvent(object context), I know I am invoking the UnityEvent with an object but my debug in SetEvent isn't being called. Any idea why this might be?

[brittle nebula]

I am asking cause I am searching for an efficient way to handle raycasting inside of a shader

so thats why

[leaden ice]

you're using object as in System.Object?

[leaden ice]

can you show the code?

[fluid lily]

yes, the method is showing up under Dynamic Object in the inspector for Unity Events

[leaden ice]

ok that should work in general

[brittle nebula]

ok so with that it narrows it down to which object, but it then still needs to do a ray intersection test for every triangle of that object?

[simple egret]

I guess, since RaycastHit can store triangle info

[hexed pecan]

Lets read
https://github.com/NVIDIAGameWorks/PhysX/blob/4.1/physx/source/geomutils/src/intersection/GuIntersectionRayTriangle.h

Ah thats for single triangle

[leaden ice]

Yeah it's unclear if that's called for every triangle in a mesh

[hexed pecan]

But probably yes, I don't think it splits the meshes into subsets of vertices/tris

[leaden ice]

it's also kind of unclear what data structure PhysX uses for mesh colliders

[hexed pecan]

So I would rather have multiple smaller MeshColliders than a monolith

[leaden ice]

I know that convex colliders are limited to like 255 triangles or something

that could definitely be a limitation due to needing to test every triangle in such operations

[fluid lily]

// variable
public UnityEvent<object> OnPerformed;

// Invoke
input.performed += (context) => {
    Vector2 arg0 = context.ReadValue<Vector2>();
    Debug.Log("OnMove" + arg0);
    OnPerformed.Invoke(arg0);        
};

// Dynamic method added to UnityEvent
public void SetEvent(object context) {
    _context = context;
    Debug.Log("Setting Context = " +  context); // This isn't showing up in logs
}

Wait why am I casting to Vector2 there one sec

[leaden ice]

Is "OnMove" being printed?

[brittle nebula]

I am just thinking cause I want to do ray intersection tests between a ray and a set of triangles which makes up an object, in a compute shader or something. So just thinking if it would be costly to do it by simply checking each triangle

[leaden ice]

Can you have each thread check a triangle

[brittle nebula]

not at once there wouldn't be enough threads, but yeah I think so

[fluid lily]

Yes it is, but the "Setting..." isn't. The cast to vector2 doesn't seem to be effecting it(it is just automatically being cast to object for the invoke call).

[simple egret]

RaycastHit
  .barycentricCoordinate;
  .textureCoord;
  .triangleIndex;

Should be enough to get you started in triangulating a point on your texture, no?

[brittle nebula]

uh, texture? I was more like thinking of sending a buffer of vertex positions to the shader and then.. that would be all I need right?

[fluid lily]

Debug.Log(OnPerformed.GetPersistentEventCount()); // => 1

So their is a registered listener, just no clue why it isn't being called

[simple egret]

Maybe? textureCoord gets you the coords of the UV texture btw, not the main texture. Not sure if you can do anything with that. Oh and this only works for mesh colliders of course

[brittle nebula]

I am confused to why you are refering to textures? For what would I need a texture?

[simple egret]

I have no idea

You said you wanted to do vertex displacement relative to a point, so it might help locating that point on the mesh

[fluid lily]

The docs seem to be doing setup of the generic UnityEvent slightly different so gonna try that first.

[narrow summit]

1. When a C# dll is put into a Unity Project, is it compiled again, or ignored altogether?
2. If I put the dll in a folder which belongs to an assembly, it does not seem to be getting packed under that assembly
3. If the answer to the above questions is (yes and that's correct), is there any way to make the API under the DLLs not show up in another assembly defined in the project?

[narrow depot]

I'm having trouble with an error:
"The same field name is serialized multiple times in the class or its parent class. This is not supported: Base(Dog) weight"

Here's some sample code to reproduce it:

public class Animal : MonoBehaviour
{
    public int weight;
}

public class Dog : Animal
{
    //int weight;
}

The Animal.cs and Dog.cs are attached to separate objects in the scene. Can somebody help me understand what's wrong?

[leaden ice]

With weight in the child class commented out you shouldn't get that error anymore

[narrow depot]

Is there a way to manually reload the scripts in the editor?

nvm

[narrow summit]

??= How does this operator work?

[simple egret]

Funky null-coalescing-assignment operator. If what's on the left of ??= is null, then it evaluates what's on the right, and puts it into what's on the left

[somber nacelle]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/null-coalescing-operator
don't use it for types deriving from UnityEngine.Object though

[heady iris]

Suppose I have a list of references to ScriptableObjects (which are specific assets on disk). I want to serialize that list and retrieve it later.

Naively serializing the list just spits out Instance IDs.

Am I going to have to slap a unique key on each SO and then have a class that can look the SOs up with that key?

The assets will not be changing (as in, their GUIDs are gonna stay constant)

[tiny orbit]

I have the following code which should take a rect transform and align one of its corners exactly with the corner of a target rect transform (vertTargetTransform). When I run this code the rects are aligned perfectly on the x axis but one corner is below the other... When I debug the xDiff and the yDiff they both say 0 even though the rects are clearly misaligned. I am doing this on a Screen Space - Camera canvas. Any ideas why this isnt working?

    {
        Vector3[] corners = new Vector3[4];
        Vector3[] corners2 = new Vector3[4];
        myTransform.GetWorldCorners(corners);
        vertTargetTransform.GetWorldCorners(corners2);
        corners[cornerToMatch] = canvasTransform.InverseTransformPoint(corners[cornerToMatch]);
        corners2[cornerToMatch] = canvasTransform.InverseTransformPoint(corners2[cornerToMatch]);
        float xDiff = corners[cornerToMatch].x - corners2[cornerToMatch].x;
        float yDiff = corners[cornerToMatch].y - corners2[cornerToMatch].y;
        Debug.Log(xDiff);
        Debug.Log(yDiff);
        Vector2 targetPosition = new Vector2(myTransform.anchoredPosition.x - xDiff, myTransform.anchoredPosition.y - yDiff);
        LTDescr tween = LeanTween.move(myTransform, targetPosition, moveDuration);
        tween.setEase(LeanTweenType.easeOutExpo);```

[heady iris]

it'd be nice to be able to just write out a list of GUIDs, but I'm very fuzzy on how that'd work.

pretty sure you need to use UnityEditor to mess with the actual assets

[unique jolt]

Hi guys, I have issue with my project build: I build the project using unity 2021.3.23f1 from Windows to mac.app, but then when I try to open it on every Mac it doesn't work...
Could somebody help me please?

[heady iris]

well that's very vague

what problem do you get?

[unique jolt]

When I click the file, nothing happens

The file doesn't open

[heady iris]

so, you're on the mac, and you double-click the application

and nothing happens

[unique jolt]

Yes

[trim rivet]

Anyone know why my particles collide with the ground but then immediately fall through it ?

[heady iris]

do you get anything if you open the terminal, navigate to the application, and then try running:

open mac.app

?

[unique jolt]

There is a message "the operation it can be completed because an error occured

[somber nacelle]

this is a code channel. perhaps you want #✨┃vfx-and-particles

[heady iris]

alternatively, see if this does anything:

./mac.app/Contents/MacOS/mac

note that the last part may be different

i'd just tab-complete it

this will try to run the executable directly

[heady iris]

I'm not sure I've seen this exact thing pop up. I usually have problems with the file being quarantined, or the executable in there not being marked as executable...

[unique jolt]

I dont know uWu
It might be a problem about security?

[heady iris]

did you try running this?

note the . at the front

[unique jolt]

No, now I'm trying

[heady iris]

i'd just punch in ./mac.app/Contents/MacOS and then hit tab to see what it completes with

[unique jolt]

nothing it doesn't work

[heady iris]

so the console printed absolutely nothing?

you ran that command, and you just got a new blank prmopt

[unique jolt]

nothing happens

zero happens

no message

no application open

nothing ahah

[heady iris]

can you copy and paste the line you ran?

[unique jolt]

I restarted the mac and , I don know how, It WORKS!!

[heady iris]

splat

[unique jolt]

very strange

[heady iris]

well, you'll want to check on other macs, if you have access to more than one

[unique jolt]

Thanks a lot for the support 😎

[heady iris]

The main problems I run into are:

• the app file is quarantined
• the executable is, for some reason, not marked as executable

(maybe another instance of Apple trying to save me from myself)

[unique jolt]

crazy ahah

[fluid lily]

Didn't solve my issue, and also seems Unity can serialize the straight generic variable now?

[fluid lily]

Issue related to that code. I am calling invoke on a UnityEvent<system.object> variable. I have a Dynamic method set in editor for it, but the method debug isn't happening(aka method isn't being called on invoke). There is a listener registered, and it's state's readout is runtime.

[bronze crystal]

i have a isdead variable = false but when i log it i says directly is true

[somber nacelle]

show code

[heady iris]

i'm just going to take a shot in the dark here

public bool isdead = false;

it's true in the inspector

[bronze crystal]

its private

[heady iris]

okay, that rules out that avenue!

[bronze crystal]

but i have this code

[heady iris]

show your code.

[bronze crystal]

    void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.CompareTag("platform"))
        {
            if (collision.contacts[0].point.z > transform.position.z)
            {
                CheckDeath();
            }
        }
    }



    // Set dead state
    private void CheckDeath()
    {
        isDead = true;
    }```

You set it to true each frame in Update (you call CheckDeath there)

[heady iris]

"CheckDeath" is a very misleading name, yes

[somber nacelle]

sets bool to true

why is this bool true?

which is probably how this happened

Yeah it doesn't check, it kills

i'm going to check your blood pressure pulls out a sword

[bronze crystal]

how to check whenever i check the front of a object

[heady iris]

i do not understand.

i'm guessing OnCollisionEnter is doing what you want already

[fluid lily]

Otherwise you can check the angle from the current object's forward and the collision.

[fluid lily]

This issue is still boggling my mind. If someone has a free moment could they check if it is working for them to use a UnityEvent<object>

oh...

[somber nacelle]

i meant actual research. not looking on youtube for ready-made tutorials that just have you repeating exactly what they do

[heady iris]

yes

the more complex your task becomes, the less likely that someone will have made a neatly packaged tutorial for you

with that said, I'm pretty sure I've watched a few videos talking about reinforcement learning in Unity...

[opaque prawn]

im not able to researched it out so help, i want to find a class/object by value(example: string)
here is my example script: https://paste.myst.rs/dtvg5d9o

[heady iris]

sounds like you want a dictionary

Dictionary<string, TheClass> will let you store and look-up TheClass instances with string keys

[somber nacelle]

yeah it's either that or they'd have to compare the value stored in the class's field with their "entered" value

[heady iris]

indeed, running over a whole list

[opaque prawn]

me google c# dictionary then

[fluid lily]

Okay, why do so many people think their question is general when it is a beginner concept of programing

😆

[latent latch]

dictionary actually a little more advance I'd say

but once you figure them out you'd use them like candy

[leaden ice]

To a beginner - almost everything sounds advanced. It's a bit of a Catch-22

[fluid lily]

Fair

[leaden ice]

I think it'd be better for the channel to be:
"a place for beginners to ask questions"
rather than
"a place to ask beginner questions"

[fluid lily]

coder-beginner
coder-generalist
coder-advanced

[opaque prawn]

thanks for making me acknowledge dictionary , there is solution i figured out: https://paste.myst.rs/s5g5gs9y

[somber nacelle]

you're treating your dictionary like a regular List so it being a dictionary is pointless

[opaque prawn]

umm its just example

[somber nacelle]

ah, so in your actual code you'll be actually using the dictionary like a Dictionary and not just like a list? if that is the case, then why are you doing it differently in your example?

[opaque prawn]

umm this example is made to... show how i want it to work? confuses

[somber nacelle]

and again, you are treating your dictionary like a list. you can accomplish the exact same behavior just by using a list and comparing the value to the property/field

[opaque prawn]

i dont think i even know what property/field is and how it works shrug

[somber nacelle]

well a field is a class-level variable

and if you don't know what that is then you may be in the wrong channel

[opaque prawn]

i should got to beginner?

[somber nacelle]

for your future questions, probably

but if the way you have this set up works for you then you do you. it's just not doing anything that requires you to be using a Dictionary over a regular List

here is what that would look like using a List instead of a Dictionary
https://paste.myst.rs/efzzwl5m

[opaque prawn]

understands the code thanks

[somber nacelle]

and if you were curious how it would look if you were actually using the dictionary as a dictionary and not just as a List: https://paste.myst.rs/rus0y0bo

of course there's also the TryGetValue method which may even be more appropriate here and that would literally just be dictionary.TryGetValue("123", out theClassObj);

[visual fractal]

I have a script which makes a player spawn at an object in my scene, and it's saying that 'Transform[]' doesn't have a definition for 'Instance'. What should I change? void OnServerSpawnPlayer() { var spawnPoint = ServerPlayerSpawnPoints.Instance.ConsumeNextSpawnPoint(); var spawnPosition = spawnPoint ? spawnPoint.transform.position : Vector3.zero; m_ClientPlayerMove.SetSpawnClientRpc(spawnPosition, new ClientRpcParams() { Send = new ClientRpcSendParams() { TargetClientIds = new[] { OwnerClientId } } }); }

public Transform[] ServerPlayerSpawnPoints;

[somber nacelle]

are you certain you have the right type there? Transform contains neither an Instance property nor a ConsumeNextSpawnPoint method. and an array of type Transform certainly wouldn't contain either of those either

or are you perhaps accessing the wrong variable

[visual fractal]

What would the right type be?

[somber nacelle]

how should i know? i assume it's probably some type included in whatever networking library you are using but i have no context for your code other than what you have just shown

[visual fractal]

https://paste.myst.rs/y8iww5dw is the code.

[somber nacelle]

this doesn't tell me anything about where you are expecting that property and method to be

have you just gone and copied code from some random tutorial without actually modifying it to work with your existing code?

[visual fractal]

No.

[somber nacelle]

then what type are you expecting to be a singleton Instance with a ConsumeNextSpawnPoint method?

[quartz folio]

I don't understand, why is public Transform[] ServerPlayerSpawnPoints; not in the code you sent

Is it in NetworkBehaviour or something

[visual fractal]

No, there's just a bit of code in between the two lines I sent that wasn't relevant.

[somber nacelle]

right but the code you pasted in the bin site is presumably the whole class, right? but the only Transform[] in that class is called spawnPoints not ServerPlayerSpawnPoints, so where is ServerPlayerSpawnPoints or is this some other class where that line actually does work?

[quartz folio]

but I'm looking at the complete code you linked, not your two lines

[visual fractal]

Ok, I'm going to do something easier and just put a capsule collider instead of a sphere collider on my player.

Machine learning chat hella dead

[somber nacelle]

and yet that still doesn't mean you should start posting your machine learning question in irrelevant channels like you were doing earlier

[wooden maple]

the last post besides me was 5 days ago 💀

where else could I post my question because clearly nobody is going to answer in the ML chat

[somber nacelle]

your question is just "how to do machine learning"
so maybe you should do some research like i suggested before

[latent latch]

could try the forums since they are usually better for more slower, complicated questions

[wooden maple]

okay thank you

[somber nacelle]

new to unity
as i also pointed out hours ago, machine learning is not a beginner topic. maybe learn how to use unity and probably also how to code if you don't already know. then at least the research you do won't just need to be "how to do machine learning but spoon feed me the info because i don't understand the context"

[mild coyote]

any double tap detection that works with getaxis? I already know how to detect ones that use keydown but detecting getaxis seems like more complex since it needs to detect the "speed" changes.
I think I can figure it out eventually, but if there's already working ones then why should I reinvent the wheel, right?

[leaden ice]

Use GetAxisRaw

So you don't have to deal with the gravity/acceleration nonsense

[mild coyote]

That what I tried first, but seems like there's a delay in value changes.
Like instead of getting the raw value, it just step/round the value

[leaden ice]

GetAxis has the delays. Raw is instant

[mild coyote]

🤔 Let me try again, maybe the problem is in how I combine the raw input and the smoothed input (I use the raw input for double tap detection and the smoothed for animations)

Yep it does works 😅
I forgot to change the stored last direction from the smoothed input to raw input
Thanks 🙂 👍

    {
        var level = PlayerDataManager.currentLevel;

        }
        else
        {

        }
    }```

[latent latch]

Not seeing anywhere you're changing scene with some sort of dynamic data

[nocturne shard]

im no c# master but how does this even compile?
"public PlayerDataManager PlayerDataManager;"

[leaden ice]

you can name fields this way but I wouldn't recommend it

As it will hide the type name going forward

[nocturne shard]

oh, huh

interesting

[rugged storm]

Oh i did not know that ill change it,

[rugged storm]

oh oops pretend that SceneManager.LoadScene(2) said SceneManager.LoadScene(level+1)

[leaden ice]

that's not any different at all

unless you also made other changes besides just that

such as eliminating the if statement(s) etc

[rugged storm]

Oh wait nm im stupid i did change something i forgot about

i added that level = 1 from when it was crashing cuz i though i had deleted it instead of commenting it out when i was trouble shooting but i just never added it

    public PlayerDataManager PlayerDataManager;
    // Start is called before the first frame update
    void Start()
    {
        var level = PlayerDataManager.currentLevel;
        var World = PlayerDataManager.currentWorld;
        if (PlayerDataManager.currentLevel == 0 && PlayerDataManager.currentWorld ==0 )
        {//new game
            SceneManager.LoadScene(level+1
);
        }
        else if (true)
        {

        }```

had that originally and I realize its because level is set directly to PlayerDataManager isn't it?

NM nm im just stupid I see the issue now...

this scene is index 1, and i forget to set level to 1 so level is 0 so its loading level+1 which means its trying to load the same scene again each time it starts

I have a compute shader, that I have used and tested on a RenderTexture, I now try to use it on a webcamTexture,

unlike renderTexture,
There is no

Hello there, I am currently looking to implement some basic debugging info into my game such as video memory usage and ram usage, I have found that Profiler can help me but Im not quite sure which of these methods correspond to what I need, for example , what can I use for Ram here?

https://docs.unity3d.com/ScriptReference/Profiling.Profiler.html

[runic skiff]

I'm creating a package. What should the asmdef's root namespace be? Should it be empty or the name of the package?

[cosmic rain]

I don't think that you can write to it from the GPU. Same as with a regular Texture2D.

[runic skiff]

Also, one of my packages is a [ReadOnlyInspector] attribute. Should I keep it in the default namespace so users don't have to using it? Or should I put it under its own namespace? I'm thinking the latter for cleanliness, but on the other hand, adding a whole using statement for one little attibute in every file you want to use it on seems tedious

Or should it be myname.mypackage?

[cosmic rain]

Are you planning to incorporate it in a production build?

Generally, I see myCompany.myPackage.branch, and for parts that are important to the whole package, is often in a core, so you could put that attribute inside of for example SomeCompany.AwesomePackage.Core, I feel like if someone is adding your package to their project, theyd expect every script to be a part of a namespace in your package, which also helps for identifying which assets/scripts are actually a part of your package as opposed to something they wrote or another package

For an asmdef, unless you expect whoever will be using this package to be extending it with their own classes and want it to be a part of the same namesapce, or your not done with it yet (to me, it sounds like your package is already done?), I dont think giving the asmdef a namespace would make much of a difference, if all the scripts in your package already have a namespace anyway

[plain coyote]

Okay, then I will just read from it I guess.

Hi! I have problem but i don't know where exactly i have to ask this question. When i build game, i can hear all audio sources no matter where they are placed, but in editor everything is correct. What can cause this error?

[glossy basin]

Pretty much, I'm aware there are some stuff that can only be used with developer symbols, but I just want to know how its done

[cosmic rain]

Seems like ProfilerRecorder is what you should have a look at.

[cosmic rain]

It seems like the marker names/profile counters can be found in the manual of each profiler module.

Still need help with that. Where can i ask this question otherwise?

[grave nebula]

I keep getting this warning and error. what happened

[lean sail]

That error warning is typically when u reuse a name that's already used

[soft shard]

Unity has some reserved names like collider, name, rigidbody, etc - in general, its good practice to be descriptive with your variable names instead of just naming it as the component, for example "playerCollider" or whatever collider its meant to represent - the error seems to be from your PlasticSCM, without more context I couldnt guess what would cause it though

[lean sail]

Someone else in here had the same error before, upgrading the version of Plastic seemed to fix it. Also others suggested to remove it

Hey,

How to reduce the amount of decimal points in a floating point number?

Like this
1.3450925
1.3450000

[dusk apex]

Maybe simply round it when you're needing to print it with string format else there's Math Round https://learn.microsoft.com/en-us/dotnet/api/system.math.round?view=net-8.0

For rounding during print use https://learn.microsoft.com/en-us/dotnet/standard/base-types/standard-numeric-format-strings for example num.ToString("N3");

or string.Format("{0.0000000}", Math.Round(num, 3));

Math Floor of your wanting to truncate https://learn.microsoft.com/en-us/dotnet/api/system.math.floor?view=net-7.0

[pallid fjord]

hey does anybody know how to make a canvas pop up to enter a code?

[dusk apex]

Is this related to scripting? What have you tried?

[pallid fjord]

i tried disable the camera when im on the box trigger

but its just stops everything

[dusk apex]

What do you mean by pop up? is the Canvas not active by default?

[pallid fjord]

ye

to sec

i find out myself

[dusk apex]

Just set it active and give it's input field focus

[pallid fjord]

huh

i try that

[dusk apex]

Show what you've tried (code).

[pallid fjord]

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

public class Puzzle : MonoBehaviour
{
public Canvas canvas;
public GameObject player;
public Camera playerCamera;

private void Start()
{
    // Get a reference to the player GameObject and camera component
    player = GameObject.FindWithTag("Player");
    playerCamera = player.GetComponentInChildren<Camera>();
}

private void OnTriggerEnter(Collider other)
{
    if (other.CompareTag("Player"))
    {
        // Set the canvas to active
        canvas.gameObject.SetActive(true);

        // Disable the player GameObject and camera movement
        player.SetActive(false);
        playerCamera.GetComponent<Camera>().enabled = false;
    }
}

private void OnTriggerExit(Collider other)
{
    if (other.CompareTag("Player"))
    {
        // Set the canvas to inactive
        canvas.gameObject.SetActive(false);

        // Enable the player GameObject and camera movement
        player.SetActive(true);
        playerCamera.GetComponent<Camera>().enabled = true;

Maybe don't set the player inactive but instead disable it's renderer component - setting the object inactive may cause the exit condition to trigger.

[pallid fjord]

ok

i try something else

i think i got an idea

[graceful ice]

where can i ask qeustions?

Your syntax highlighting is not correct

Or correct me if you do get proper autocomplete on functions such as GetChild, then it's fine

[stoic flame]

I did

[soft shard]

If "enemy" is a prefab, your currently trying to set the parent of the prefab, and not an instance of it - Instantiate returns a GameObject, so you could instantiate into a variable, then set the parent of that variable instead, or Instantiate can also create an object into a parent provided as a second parameter, see the second overload in the docs: https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

Hi, I'm new in this discord, but my teammate and I have a problem. We are creating a race on Unity. The textures of the circuit created are so good (my mate has a talent), so put the project as HDURP, but that makes the camera vibrate by not refreshing the project would need. At the moment, we have had to put it to RP to complete the game, but it is a pity that the work done is not appreciated. Would anyone know how to help us? We now we have to do something in the script part but we doesn't find anything (we are students)

[stoic flame]

You mean this one?

public static Object Instantiate(Object original, Vector3 position, Quaternion rotation, Transform parent);

[wide mural]

The camera is inside the vehicle (well, looking at the steering wheel)

[soft shard]

You could use that one if you also want to specify a rotation with the parent, or just the parent if you want the rotation to be defaulted

[stoic flame]

ok

[pallid fjord]

ok i got it to work now

does anybody know how to get your mouse out from the camera

and being able to click on the screen

sry for my horrible

[primal wind]

Cursor.lockState = CursorLockState.none something along that

ok

it worked

[languid pilot]

Is there a way, to make app self checking if there is new update ready on google play, so player will get in-game notification like "Hey! there is update to download!"

[hard estuary]

Here is a tutorial that explains this topic:
https://www.youtube.com/watch?v=TA8B_jmjhX8

[steady granite]

Ideas on how to make small TMP texts more sharp? Google gives mostly tips for the old Unity UI Text component, but not much for TMP.
Tried changing the font, it does get sharper with some other fonts but I think there is something else...

[languid pilot]

Oh, how i missed that. I've google this question and this video didn't show up
thanks you

[grave nebula]

Loll it was there since i created the project

[grave nebula]

Ah, this is why tutorials don't always work xd

[hard estuary]

The sharpness depends mostly on the font size. E.g. a huge font size with a small object scale gives sharper effects than a small font size with a huge object scale.

[steady granite]

I have seen this on old posts for Unity UI Text but does no effect in my case (tried a 10x font size, 0.1x scale and reversed but litteraly the same results)

also AA is disabled in my URP so it should not be related

[scenic hinge]

Why does Unity precede fields with m? And is there an official Unity coding conventions

[steady granite]

To me these look exactly the same

[heady iris]

have you tried adjusting the settings on the text material? you can control softness (0 by default, probably not gonna help here) and dilation (which will make the text become thicker or thinner)

the latter might help

dilation at -0.19 vs at 0

note that if you just adjust the one that's on the text by default, you'll be changing the material for all text...so you might want to make a separate material 😛

i was looking to see if there was an option for controlling hinting, but I'm not sure that's a thing for this style of font rendering

[steady granite]

this does help a bit around -.2 but you can still see the text kinda weird "mushy" borders (renders perfectly on scene view when zoomed in but this is not rendered the same way)

[heady iris]

is your game view rendering at a fixed resolution and getting scaled?

i.e. is the Scale slider not at 1x

[steady granite]

it is at either 16:9 or 1080p rendering and always 1x scale

[woeful spire]

made any changes to the shader?

[quartz folio]

What does this have to do with coding

[heady iris]

where should this one go, actually?

[quartz folio]

#📲┃ui-ux

[heady iris]

#📲┃ui-ux , i guess

yeah

[steady granite]

no, standard shader

[steady granite]

right, not always sure where to post on this discord I will move it there

[edgy pike]

is there a difference between unity random.range(-1f,1f) and random.range(-1,2)? as in the difference between using the int random vs the float random? if I have the choice which should i take?

[leaden ice]

yes there is a difference.

[vagrant blade]

The difference is one is an int and one is a float.

[leaden ice]

the int version only returns integers

[hard estuary]

The min and max values are the same, but the first one can return fractions such as 0.0123f

[edgy pike]

apart from the int-float difference. I only need full values anyway

[steady granite]

also int is max included, float is max excluded iirc (might be reversed)

[hard estuary]

If you need full values, then there is no point in using floats.

[heady iris]

Random.Range actually has an inclusive upper bound

weird fact

[edgy pike]

but only with floats

[heady iris]

ah yeah, forgot to specify :p

it's very unlikely for the inclusive float range to matter, but it is a possibility...

[leaden ice]

there is no difference other than the int-float difference but that's a huge difference. In fact Random.Range(-1f,1f) will only extremely rarely generate -1 or 1 whereas Random.Range(-1,2) will generate -1 , 0, and 1 1/3 of the time.

[edgy pike]

this is why my example is as it is ;D yes, so i got it. when i need ints anyways, always use int version of random.range. my specific example would be

var random = Random.Range(-1f, 1f);
return random >= 0 ? 1 : -1;

[heady iris]

the odds are roughly..i dunno, one in a few billion

[edgy pike]

so i go there with int version as well

[leaden ice]

So even if you';re doing Mathf.Round or Ceil or Floor, you're going to get very different numerical distributions with the float version vs the int version

so it's not only more code but also probably not the result you want

[heady iris]

indeed

use the integer version to pick things

use the float version to place things

[edgy pike]

thanks!

[heady iris]

that reminds me of something really useful

https://docs.unity3d.com/2022.2/Documentation/Manual/EditingValueProperties.html

you can use R(-10,10) to get a random value from -10 to 10 in the inspector

if you're multi-editing, each object gets its own value

[edgy pike]

thats neat

[open rain]

Hey guys , is anybody here familiar with AstarPathFinding? I am trying to use it for pathfinding in 2D and it works super well.
But there is a problem where the agent doesn't really "care" to collide with stuff unless its its super in him . Like on pivot I think. Anybody knows how to fix it? Thanks in advance :) tag me please <3

[hard estuary]

A* pathfinding is quite a popular algorithm and has plenty of different implementations. Issues may vary depending on the version.
If it's based on the NavMesh, you should adjust the agent settings in Window/AI/Navigation window. The bigger the radius of the agent is, the further your AI will stay away from obstacles.

[open rain]

Thanks but I am not sure if its based on navmesh but I don't think it is

[hard estuary]

If you haven't generated any NavMesh, then this algorithm probably doesn't use it and is based on something else. Can you post the link to this asset?

[somber nacelle]

jesus don't crosspost

[open rain]

Holly chill

I asked before and no one answered so I asked here

I half got it to maybe work

[hard estuary]

I suppose you can increase Diameter in GridGraph.

[open rain]

No really xd , It just makes the grid "cells" bigger diameter which is not something that will help

I found a way for it to work

Kinda

[somber nacelle]

it's both node size and the diameter on the collision settings of the gridgraph as i've already pointed out in the other channel

[open rain]

The is not 100% correct tho and it doesn't not help me to solve the problem

[somber nacelle]

prove it

[open rain]

K

[somber nacelle]

because it is correct for what you've described as the issue

[open rain]

Let's say ill increase the diameter to 5 okay? what shall happen then?

I am 100% wrong

[somber nacelle]

then it will expect your agent's diameter to be 5 nodes wide. which will mean that there should be a gap 5 nodes wide around obstacles to make your seeker actually go around them

[open rain]

Lmfao

Anyway

Mistakes happen

Thanks for the help @somber nacelle But I will sidenote that even if you are not trying you are a bit aggressive lol . it's not a bad thing just something that you should note for later :) Have a good one cya!

[somber nacelle]

maybe next time stop expecting people to just guess at what your issue is?

[open rain]

You are doing it again and I won't argue I'm just letting you know! I hope you have a wonderful rest of your week!

[cobalt kraken]

I need assistance and I feel like im going insane. I have a player who has a gun (2D Top Down). The gun has a shoulder behavior, where its not DIRECTLY apart of the character but a child that rotates around the parent. I want the sprite to flip when the gun is on his left but it absolutely won't. If anyone can help me, I can DM you the code I have for you to look over rq

[somber nacelle]

if you want to share code, you do not need to DM it. follow the bot's instructions for sharing !code

Thank you

Note that the isRight bool isn't currently being used

[somber nacelle]

you're comparing transform.rotation.z which is part of a quaternion which means it can never be greater than 90 or less than -90 considering quaternions 1) do not deal with angles in degrees 2) are normalized

i'd say switch to using transform.eulerAngles.z but you really shouldn't rely on eulerAngles for logic, you could instead have this component communicate with whatever component is rotating your player to flip it when necessary

[cobalt kraken]

I gotcha. I did switch it up to Eulers, and its still not working but it HAS improved and seems to be at least responding now. I can def work with this. I appreciate the help

[heady iris]

euler angles are annoying because they can be discontinuous

you do a slight rotation and bam, all three components changed significantly

[cobalt kraken]

Yeahhh, they def are finicky, I did figure it out though, all is working well. I decided to get rid of the euler angles bc of that actually and used the local position point in comparison to the parent instead. Much smoother than trying to deal with the angles. Thanks for the help and info!

[heady iris]

I'm still hemming and hawwing about this for a save system. I could use some hot takes on the matter (:

I'm a little unclear on how the conversion from the unique id (e.g. a GUID) to the scriptable object asset would work

I guess it'd be a Resources.LoadAll<TheSOType>()

and then just make a dictionary out of that

oh, yes, that's absolutely how that'd work 🦆

[leaden ice]

Look into the Addressables system

[heady iris]

or, perhaps, something Addressables related? I just need to fetch all scriptable object--

ah, there it is :p

I have it in the project already for Localization. I will give that a look.

I imagine this will be a relatively simple application of them. I'm not exactly loading hundreds of megs of assets from a remote server here.

[heady iris]

One question about that: Would it be possible to store and load references to specific Addressable assets? i.e. could I store a reference to an asset and then use that to pick the same asset later?

something along the lines of looking at the asset's GUID in-editor

or do I need to go ahead and put a unique key on the scriptable object?

the intended application here is remembering a list of save points you have reached

each one will have a reference to a scriptable object (that is unique per-save-point)

currently that object is just

using UnityEngine;
using UnityEngine.Localization;

public class SavePointSpec : ScriptableObject
{
    public LocalizedString label;
}

[rugged storm]

i have this script that makes a grid of tiles then adds each tile to a Dictionary with their key being thier position, I just changed it such that each tile is a child of the "grid" empty object but now my tiles list is returning null.

[heady iris]

as in, TileData is null?

[rugged storm]

No, "tiles" the dictionary i add to at the end of this foreach loop is causing null reference errors when I try to call foreach loops on it later

[potent sleet]

this is a custom grid not the unity one ?

[heady iris]

one thing that jumps out at me: do not use Vector2

floating point errors abound

Vector2Int will be much more reliable.

[rugged storm]

ah kk

[heady iris]

are you sure these are null reference errors and not "item does not exist in dictionary"?

[rugged storm]

particularly in pathfinding when I go to make all the nodes, I'm getting a NullRefrenceExeption on line 27(the foreach line)

[heady iris]

that means you don't have a tiles dictionary at all...

i'm pretty sure it's fine to put null in a dictionary

that wouldn't cause an error in its own right

(or maybe GridManager.Instance is null)

[rugged storm]

it shouldnt be? i dont even know how it would be. like its attached to an empty in the scene called GridManager if you mean that it might not be on an object

[heady iris]

well, go check it!

log those things before you hit line 27

merely having null values would not cause an exception in the foreach line

[somber nacelle]

it also matters when you call these methods

[heady iris]

indeed

as anyone who has tried to sit on a chair that just got pulled out from beneath them can attest to

[pliant gorge]

Hi there, i'm having an issue with syncing my Network Variable is this the right place to ask about this?

[heady iris]

check #archived-networking

[pliant gorge]

thanks

[rugged storm]

okay its weird becuase, I put a break point at the bottom of the FormGrid method and the tiles dictionary filled up with tiles correctly... and its still correct once I reach the MakeNodes foreach loop in pathfinding (i put another break point there) but then it throws the error...

[heady iris]

it throws the error from the foreach line?

and you are confident that GridManager.Instance is not null and that GridManager.Instance.tiles is not null?

[rugged storm]

Yeah,

none of the objects in the list are even null

[heady iris]

have you proven this to yourself by logging all of these things?

i'd do it even if you think that's the case from the debugger

might as well see exactly what it sees

[potent sleet]

yes you don't know until you know

[rugged storm]

wym by logging? just by passing through Debug.Log?

[potent sleet]

debugger should be your first resort

Attach to Unity

[rugged storm]

oh yeah i did that

[potent sleet]

You should be able to see what's null then
