[odd arrow]

nah bc that takes full png or jpg bytes

the code here iterates each pixel in my image and writes rgba bytes to that byte array

and then gets loaded by the texture after it's done

[spring flame]

[ScriptedImporter(1, "someExtension")], that's how importers are annotated and unity later knows which importer to use for which kind of asset

[leaden ice]

COuldn't you just use this then:
https://docs.unity3d.com/ScriptReference/Texture2D.SetPixels32.html

[odd arrow]

unrelated though is it not? still have to save that Texture2D asset to exist in the asset browser either way

[spring flame]

btw may I ask out of curiosity why raw bytes for rgba?

you said you wrote custom parser, so this is a bit... off-putting to me (rises some flags, not sure if I used this phrase correctly)??

[leaden ice]

https://docs.unity3d.com/ScriptReference/ImageConversion.EncodeToPNG.html after importing then save the PNG?

[odd arrow]

that's what tooster recommended, it sucks they would all have to be saved to pngs as well but i assume it would work

[odd arrow]

ik it's probably against the rules here bc proprietary content n stuff but i wrote a PoC nds rom parser and im loading pixel data from textures extracted from there

for purposes other than wanting the extra texture import settings, my code works perfectly fine for pixel data n all that

[leaden ice]

Looks like you can do this:
https://docs.unity3d.com/ScriptReference/AssetDatabase.CreateAsset.html
Just using a .png path and a Texture2D for the asset object

hmm maybe not actually

[spring flame]

To my current understanding, if you want to use the TextureAssetImporter, you have to use the filetape that this importer supports

[leaden ice]

yeah if you just want a serialized .asset containing a Texture2D you use CreateAsset

[spring flame]

and as a possible workaround, you could maybe create a derived class from TextureAssetImporter, annotate it with [ScriptedImporter(1, "yourMadeUpExtension")]

and store the asset with this made up extension

and in relevant methods call base....() if possible

[odd arrow]

ughhh TextureImporter is sealed

[fossil steeple]

@rigid island

[SerializeField] private LineRenderer LineRenderer;
    [FormerlySerializedAs("LayerMask")] public LayerMask PlayerMask;

    private void Awake()
    {
        LineRenderer = GetComponent<LineRenderer>();
    }

    private void Update()
    {
        Ray ray = Camera.main.ScreenPointToRay(new Vector3(Screen.width/2, Screen.height/2, 0));
        RaycastHit hit;
        
        if (Physics.Raycast(ray, out hit, Mathf.Infinity, PlayerMask))
        {
            Debug.Log($"Looking at {hit.collider.gameObject.name}");
            
            LineRenderer.SetPosition(0, transform.position);
            LineRenderer.SetPosition(1, hit.point);
            LineRenderer.startColor = Color.green;
            LineRenderer.endColor = Color.green;
            
        }
    }

[spring flame]

welp, then I guess going with the route of supported asset types is the best option

[odd arrow]

yeah unfortunately

[leaden ice]

I think the answer is to build a Texture2D with SetPixels32, do the EncodeToPNG on it, write the PNG file out manually, then call https://docs.unity3d.com/ScriptReference/AssetDatabase.ImportAsset.html to import it as an asset

[odd arrow]

sadly that's probably the only option ugh!!!

[spring flame]

I don't quite understand what's so bad with that, why do you try to avoid having .png and want to keep .asset 😅 ?

[odd arrow]

well bc that means for each texture i've gotta convert to png and then reimport so that doesn't end up keeping everything within unity and the code

maybe it wont be so bad tho

[leaden ice]

If you want to keep the .asset then it should work fine to create the Texture2D with SetPixels32 and then call https://docs.unity3d.com/ScriptReference/AssetDatabase.CreateAsset.html

[deft dagger]

hey, why doesnt this code work ?
var content = JsonUtility.ToJson(userPost);
Debug.Log(content);

[rigid island]

also screenshot the line currently and how it looks,, I haven't used CM pov much

[odd arrow]

the pixel loading is irrelevant to this but i appreciate the help

imma probs just suck it up and live w/o import settings

[rigid island]

define "doesn't work"

[deft dagger]

the debug log thing just prints: {}

[leaden ice]

souinds like userPost was not a serializable type

or has no serialized members

[rigid island]

something you trying to serialize maybe isn't serializable

yup

[rigid island]

show userPost obj

[deft dagger]

this is the class of userpost

[leaden ice]

Unity cannot serialize properties

those are all properties

it can only serialize fields

[rigid island]

use Json.Net

much better

JsonUtil is garbo

[deft dagger]

how ?

[leaden ice]

you could optionally serialize the backing fields for those properties with [field: SerializeField] on each property if you want.
e.g.

[field: SerializeField] public string userName { get; set; }```
@deft dagger

otherwise switch to fields:

public string userName;```

[rigid island]

https://docs.unity3d.com/Packages/com.unity.nuget.newtonsoft-json@latest

[leaden ice]

is there a good reason you need them to be properties? They seem to all just be autoproperties

[fossil steeple]

It's the purple color, even tho I am setting it to green

[deft dagger]

im trying to get them to use them with http client

[leaden ice]

the magenta means you are not using a valid shader for this render pipeline

[leaden ice]

Irrelevant

[deft dagger]

but because it gives an empty object its returning an error that they are empty

[leaden ice]

the only thing your HTTP client sees is the serialized json

so switch to something you can actually serialize

or switch to a different serializer

[deft dagger]

so i should just delete the get set ?

[leaden ice]

that's the easiest/simplest way forward, yes.

[deft dagger]

i see

[rigid island]

hmm maybe try just passing
var ray = cam.ViewportPointToRay(new Vector2(0.5f,0.5f));

[deft dagger]

i will try that now, thanks

[rigid island]

keep in mind with jsonutil , if you use dictionaries you need another workaround

[leaden ice]

this would be for ViewportPointTORay

[round violet]

any ideas ?

[rigid island]

oops yea you're right

[leaden ice]

if you just want ray from the center of the camera you can do this:

Ray r = new Ray(camTransform.position, camTransform.forward);```

[rigid island]

@fossil steeple ^^ this

[leaden ice]

either selectables is nuill or selectables[_currentSelection] is null. Find out which with some log statements or the debugger

[round violet]

as you can see in the inspector the list has correct entries
as you can see with the debug log, its trying to get 0

i did some test with hardcoded indexs, same error

[leaden ice]

That inspector tells me that some instance of the script has correct entries at one point in time

[round violet]

i just edited the code by adding more list entries and now its not working (or maybe its the panel ?)

[leaden ice]

When your code is erroring, it's either on a different instance, or at a different time when there are null entries

[round violet]

i only have 1 instance of this mainmenu

[leaden ice]

YOu are still skipping the very first step of debugging here

figure out exactly what is null

[round violet]

well its the lists entries

[leaden ice]

add debug logs or attach a debugger

[leaden ice]

how do you know that?

[rigid island]

^^ debugger is your best friend

[leaden ice]

it could be the list/array itself

[round violet]

because its saying its null

[leaden ice]

There are two possibilities of null things on that line

[round violet]

then if its null, why is it showing the correct data in the inspector at all time ?

[fossil steeple]

@leaden ice
How am I gonna ignore my player this way though?
since my camera is set to look at my player all time

[leaden ice]

Rule #1 of debugging is to quiestion your assumptions

[deft dagger]

it worked ! thanks man

[leaden ice]

Already answer3ed this #archived-code-general message

[fossil steeple]

I am using URP
didn't change anything really
anyway to fix this?

[leaden ice]

upgrade your material

[round violet]

i said i only have one instance, and the list is never changed at runtime

so i dont see why the entries becomes null

[round violet]

i already perfomed many checks before asking here dont worry

[leaden ice]

you are making assumptions. THe only way to know for sure is to debug

everyone goes through this. Stubbornly resisting debugging. When they finally do there's usually an "Oh! Of Course" moment and the problem is solved instantly

For erxample you're assuming the code is actually running on the instance of your script in your scene

maybe it's running on a prefab, for example

[round violet]

for example; i made a foreach, its printing all objects, but throws an error for one of them

        Debug.Log(_selectables.Count);
        foreach (var selectable in _selectables)
        {
            Debug.Log(selectable.gameObject.name);
        }

[round violet]

i am not stubbornly not debugging, i already debugged and not finding the issue

[leaden ice]

Very clear from this screenshot that you have two copies of the script

[rigid island]

ignore the player layer , also if you use the third person mode in cinemachine you can offset the shoulder area

[round violet]

you are right, apparently i misslicked by applying a prefab changed to the parent

im sorry if i appeared rude, ty for helping out

[heady iris]

as Sherlock once said:

When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth

[knotty sun]

one of the most difficult tasks in software development is to not make assumptions and know. it's like looking at a line of code and seeing what is actually there rather than what you think is there. The mind plays tricks on you

[round violet]

[heady iris]

It's useful to start with assumptions, but to then quickly relax them

I don't immediately check "does this object even exist?" if a new piece of behavior doesn't work, since I know it does probably exist.

But you need to be able and willing to start challenging those assumptions.

[knotty sun]

you guys are lucky, imagine us poor bastards before the days of ide's and debuggers when all we had to go on was a screen full of hex

[round violet]

yeah i usually check all my code, even if i dont see why there should be an issue

but here it wasnt a code issue but an wrong human movement

[knotty sun]

but it caused a code issue, one of the reasons I always debug the instance id of the object so you can instantly see if it's the object you think it is

[round violet]

how can you debug the instance id ?

[rigid island]

make debugger your best friend

[knotty sun]

Debug.Log(GetInstanceId());

[heady iris]

every unity object has an instance ID on it

[round violet]

that great, didnt know it existed

[knotty sun]

also useful info, prefabs have positive id's scene gameobjects have negative id's, so it's easy to see if you are referencing a prefab by accident

[lean sail]

Smells like some decompiling business. Unity compiles code automatically for you, you dont need to do anything yourself. Sounds suspicious that you have "source code" yet dont know how to compile it

Is this some publicly available code you just downloaded? How was it shared? I assume this was given via github, so the project should be playable as soon as you open it in unity.

Ask about the specific errors in that community you mentioned. Fixing them yourself might require you to learn some basic coding. Modding/decompiling talk isnt really allowed here or I'd offer to help further.
The errors could even just be nothing, unless you cannot run the project at all because of it. It could even just be an error because of a unity version difference

[lilac burrow]

I have no clue what to do. Ill just get rid of my messages not to clog the server and go on my day. I would happy to learn unity and stuff but alot of stuff is going on in my life now.

[lean sail]

Best bet is what I said in my previous message, show the community that you mentioned the exact errors. They likely know how to fix it

[old coral]

Hey, I've got a question for those a bit more experienced , I'm relatively new to Unity after switching from Gamemaker and so far have a pretty decent setup for my current project where I'm working on a saving/loading function and I use a tilemap for building structures and want to save the full tilemap and convert it to a string so it can be saved correctly which I have managed to setup, the only issue I have right now is it seems like the game is only saving a certain section of the tilemap and ignoring the rest as when I load the save I can only see tiles I placed in that particular area. As far as I am aware the save function is checking every possible tile that can be built on so it is confusing to know what i'm missing here. I consulted ChatGPT which suggested checking the tilemap bounds are set correctly which I am not sure where to check this in the editor either, Any help on how to check tilemap bounds or another method to try saving the tilemap would be great , Thanks

[timid pebble]

Would anyone know any reasons as to why omisharp is not starting in vscode (no omnisharp logs)? I had intellisense yesterday, but opening the project today its not working. I have the latest mono version, dotnet 6, and omnisharp.UseModernNet set to false

Also for some reason, everytime I come back to Unity, there's always something that goes wrong with intellisense in vscode

[cosmic rain]

Start from sharing the relevant code.
Did you check the saved string for wether it contains the missing tiles data?

[foggy phoenix]

Question on Pac-Man Clone Based on Guide Playlist

[rigid island]

you're using old method which is outdated

[rigid island]

yeah thats because VSCode isnt officially supported by unity

flawless experience would be Visual Studio

or Rider I suppose if you can afford it / are student

anyway the new method for vscode is outlined here below ⬇️

weird way to say it's supported but the extension has changed and is now developed by microsoft 😛

[quaint rock]

yeah it was only dropped for a bit till ms picked it up themselfs

though i am partial to team here

[rigid island]

yeah Microsoft but Unity for some reason doesn't care to support it even though they use it themselves lol

[quaint rock]

why spend the resources is MS alreayd is

[rigid island]

Microsoft made smart move for market share

[quaint rock]

the Rider one is also included in the package manager too but is all maintained by jetbrains

I can't seem to get this script to work, it has 2 errors, that the problem, is that its suppose to be a 2D sprite adventuring around a 3d climate, follow camera, able to rotate around like a computer mouse.

[rigid island]

those are warnings , its saying your current animator controller doesn't have those parameters

[bold wraith]

do you know how to solve the problem?

[rigid island]

https://docs.unity3d.com/Manual/AnimationParameters.html
Add the parameters

[bold wraith]

that part is what I have of parameters

[rigid island]

are you sure this is the controller you are using on the Animator component ?

[bold wraith]

that's what I have set

[rigid island]

can you show the inspector for that

[rigid island]

thats not the animator component

[quaint rock]

its the inspector for a blend tree

[bold wraith]

is that it?

[rigid island]

thats the Animator Controller mate

the Animator is on the gameobject itself

[bold wraith]

this one?

[rigid island]

they seem different

and yea thats the one

character_animator1 vs player.controller

[rigid island]

SpriteDirectional is the script thats causing those warnings?

[bold wraith]

Yes.

[rigid island]

can you show script

[bold wraith]

ok

copy and paste a screenshot is ok?

if you're committed to debugging

[bold wraith]

debugging I am committed to doing

I assume that the player controller doesn't have keys setup

the input of " w a s d"

[cosmic rain]

I thought you had an issue with the animation? What do the controls have to do with it?

[bold wraith]

the animation is created, but the keys don't seem to do anything when I press them

[cosmic rain]

Maybe start from explaining the issue in details before moving on to debugging. Share a video of it if words are not enough.

[rigid island]

you have none of that in this code

[bold wraith]

ok lets get the code adjusted then?

[rigid island]

where would that be?

you have to code stuff in its not magically there

[bold wraith]

i remember setting up a controller, but it took some time

isnt there a package of it?

[rigid island]

there is a built in Input class

there is also a newer Input System unity released as package

[bold wraith]

whats the name of that?

[rigid island]

the name of what ? Input System, I just said it lol

[bold wraith]

ohh

[cosmic rain]

The input system is not gonna add character controller logic for you. You have to code that.

[rigid island]

I wouldn't worry about that now, learn the "traditional" way first

[bold wraith]

okay

i installed the input system for later

where can we start the code at?

[cosmic rain]

Start by going through unity learn or looking up a tutorial for a character controller that suits your need.

there is always a way, you have too choose if you want to code that in or use a plugin

https://developer.android.com/reference/android/os/StatFs.html#getAvailableBytes()

[thin shoal]

code it in if it just something simple and basic as in get how much free space left. oh.

does unity have that built in?

[rigid island]

you're in a code general channel, that should be expected..everything is done in code

[rigid island]

in internal api no

[thin shoal]

so not built in

if it in a plugin scenario

[rigid island]

something like this maybe ?
https://github.com/dkrprasetya/simple-disk-utils

[broken jewel]

Hi, i've found a script from an old folder in my pc, what it does is actually extract out the trees painted on the terrain as the original prefab in the world space (detached from the terrain) , but the problem is , all the painted trees grab the scale of their root prefabs , and the size variation of them when being painted on the terrain is lost, my question is, is it possible to keep their random scale retained even after they are extracted out from the terrain? (long words sorry)

here is the part of the code below

[cosmic rain]

TreeInstance seem to have a widthScale and heightScale properties which are supposed to correspond to it's scale.

[broken jewel]

remove instance(j)?

[cosmic rain]

Oh, you're using it there.

What exactly doesn't work?

[broken jewel]

everything works okay, it was supposed to extract out the painted trees from the terrain to world space and copy the root prefabs world scale ...i mean , all the bamboo trees are extracted out from the terrain , and they are now individual game objects, ...here i just want to make a little change, i want the trees have their scales(height , width) unchanged like they were painted on the terrain with random height ...instead of the inheriting the scale of the root prefab, because , when they get detached or extracted from the terrain , all trees have same heights , which is against the true nature ..haha

[bold wraith]

my sprite doesn't seem to move by my command, it seems to do an auto movement

[frosty snow]

ok i finally got a basic scripting system working

[bold wraith]

I added an Xbox controller to it, but doesn't work to operate a sprite to me yet.

[cosmic rain]

Well, your code should already be doing that.

[broken jewel]

it somehow doesnt 🙁

those little kids are the extracted ones

[cosmic rain]

How are they supposed to look? And is the prefab scaled as 1 1 1 by default?

[broken jewel]

sorry , i have notice another thing , it doesnt even inherit the scale of their root prefab

just a constant number 1.09 or something on x,y,z scale

[cosmic rain]

Because the width and height scale are relative to the original prefab scale, not absolute. You'd need to multiply it by existing scale if you want to keep the prefab scale.

But ideally you want your prefab unscaled.

[broken jewel]

yeah, i just want to leave the trees scale as is painted like on the terrain

im not good at coding, could you just guide me where to modify?

[cosmic rain]

You'd need to learn it then. It's not that hard. You just need to multiply the scale from the terrain data with the prefab scale.

If you're having trouble with coding I suggest to step back and do proper learning before continuing.

Hey guys I'd like some help with a problem that's been driving me nuts

I'm trying to get an orbital rotation working but I have a problem when I move from one 'planet' to another.

This simple function works when I start with the correct orientation inside the gravity of my object, which is recognized by a trigger collider.

    private void RotateAroundObject()
    {
        player.transform.RotateAround(transform.position, direction * player.transform.forward, orbitSpeed * Time.deltaTime);
    }

I'm trying to fix my weird behavior by aligning the box collider of my object and the circlecollider of my planet

If anyone has any advice on how to implement this I'd be most grateful

[latent latch]

can you explain the issue more beyond it just not working

[junior wind]

current behavior is the rotation is fixed around the point of contact between the two colliders.
My idea of how to fix it is by having the center of my box collider travel along the edge of the circle collider.

I will then need to ensure that the rotation is correct and add some logic to have the rocket spin correctly depending on the orientation it approaches from

[lunar python]

why dont you just use a spin function using mathematics instead of relying on circle collider

[junior wind]

the collider acts as the trigger for the rocket to begin orbiting a planet

[latent latch]

public static Vector3 RotatePointAroundPivot(Vector3 point, Vector3 pivot, Vector3 axis, float angle)
{
    Quaternion rotation = Quaternion.AngleAxis(angle, axis);
    return rotation * (point - pivot) + pivot;
}

This is my rotatearound method I've made which behaves similar if you can figure out your logic from that

there's a reason I use this over rotate around but I forget

oh, right. It's not tied to transform

[junior wind]

already doesn't like it in 2d :/

[latent latch]

Ah, can do all operations in 3D then just return as 2D. I think that should still work

it's just an alternative though from rotatearound but it's basically similar logic if you wanted to know how it worked

[junior wind]

I tried it as is with

player.transform.position = RotatePointAroundPoint(player.transform.position, transform.position, Vector2.right, orbitSpeed);

and my rocket is stationary

did I misunderstand any of the args?

[latent latch]

wouldn't it be z that you rotate around

rather, the axis of rotation

[lunar python]

why arent we using the standard matrix multiplication to orbit the object

[junior wind]

I'm not familiar with this

[junior wind]

yeah that fixed it, but then it introduces the issue of having to adjust my rotation every frame

[latent latch]

right, you set your look direction too

or by the cross product

[lean sail]

Because it's not needed, matrix is a lot more values and we have built in quaternion functions that do most of what's needed already

Matrix multiplication alone means nothing here though, i assume you mean transformation matrix

[latent latch]

I mean, if you're trying to emulate the gravity pull and rotation, I'm not too sure this method (or rotatearound for that matter) is the idea, but if you want consistent rotation around the object then this works.

[junior wind]

nah not that granular, just a simply circular orbit is fine

the concept here is to jump from planet to planet and be able to orbit each one

[latent latch]

I use it to spin fireballs around me because applying velocity with rotation values eventually build up rotational drift (floating point problem) so just calculating the point every update keeps it accurate

[junior wind]

also, as I'm reading into it, lookrotation seems to be a function in 3 dimensions, and I guess getting an orthogonal vector in 2D also gives me a 3D vector

but it's been a long time since math and physics so 🤷‍♂️ lol

[lunar python]

you could make 2 AddForce to the orbiting objects. One towards the Current Object Position projected onto the orbiting line. and one is your already orbiting direction

[lean sail]

Not really sure what you mean by that, but you do not magically get a 3d vector from 2 orthogonal vectors

Orthogonal just means dot product is 0

2 orthogonal 2d vectors would just span the 2d space

[lunar python]

all of my rigidbody is kinematic so I have to configure my own physics system

kinda annoying but more choices

[junior wind]

I X J = K, no?

[latent latch]

z still kinda exists in 2D as I guess you can see that we're rotating on it. You're still like looking at it if it were being moved around on a table, so there's still that axis of depth and even if you don't move on it, it's still relevant

technically 4D if we're using quaternions but I've no freaking clue how they work

[lean sail]

I'm not really sure what you're referring to by this but regardless you dont really need to know much true linear alg for unity.

[junior wind]

okay my bad, I'm probably all over the place as I'm trying to learn how to incorporate these concepts

[lean sail]

Either you are referring to some advanced graduate level concept beyond my knowledge, or have a big misunderstanding 😅

[junior wind]

it's definately the latter lol

back to the problem at hand, what should I do to keep my rotation consistent with my position as I orbit?

RotateAround kinda did both for me, and I mean it worked fine until my rocket hit the trigger of a different planet

[lean sail]

What happened when it hit a different planet?

[latent latch]

probably want to check distance before rotating

use OnTriggerStay

[latent latch]

then check inside of it

[junior wind]

there we go

[latent latch]

this with rotatearound? Doesn't seem to keep the direction either

[junior wind]

yeah this is with rotatearound

[latent latch]

in that case you'd have to calculate the direction each update if you want to facing to be accurate

but if you want to do it the easy way, just get a direction from the last position ;)

[junior wind]

🤔

[latent latch]

but otherwise the object's rotation doesn't matter

[junior wind]

what do you mean?

[latent latch]

rotatearound just lerps a position around a point without any regards for the rotation

like, you're not applying forward velocity anywhere here

[junior wind]

oh, yeah.

I only apply a force to apply thrust, and I turn off my collider for a second so it doesn't interfere with my trajectory while in bounds

otherwise it's simply rotatearound the whole time

[latent latch]

that's probably your fix anyway so try that

[junior wind]

I just need the rocket to orient properly when it hits a second planet and I can breathe again

hmm so if distance < radius - someValue then start spinning?

[latent latch]

yeah, and then you can probably just define the orbit radius per planet

[junior wind]

cool, I'll give it a shot

[latent latch]

you want to check it inside of the trigger, so that should always be further than the radius

another idea is to use MoveTowards

with conjunction so it always moves to the radius

incase you overshoot

[junior wind]

yeah my first idea was to move the center of my box collider ride the edge of the circle collider but I couldn't figure out how to calculate the closest point on the edge of the circle every frame.

[latent latch]

well, it does two things, moves you towards the planet or moves you away if you want that

I use it a bit to make some spiral effects with my rotational methods

both methods are just lerping methods with a little more logic

[junior wind]

welp 1st attempt didn't work

    void FixedUpdate()
    {
        if (pcG.orbitingBody != null && pcG.orbitingBody == gameObject && inRotateDistance())
        {
            RotateAroundObject();
        }
    }

    private bool inRotateDistance(){
        return player.transform.position.magnitude - orbitDistance > Vector2.Distance(player.transform.position, transform.position);
    }

man I'm bad at this 😓

[latent latch]

just orbit distance

orbitDistance >= Vector3.Distance (if orbit distance is greater, then we are in orbit and should rotate)

I think? Too sleepy but just comparing scalar values

anyway gtg, if you're continuing to have troubles, be sure you're logging your stuff

[junior wind]

Thanks Mao

[sand vine]

Hey, is there a built in method that can resize rect transform width with automatic position change so the rect won't move? Same as when we drag for example right size of a resize tool in rect transform

[knotty sun]

https://docs.unity3d.com/ScriptReference/RectTransform.SetSizeWithCurrentAnchors.html

[sand vine]

I tried this but doesn't work for me sadly. I can pass only horizontal axis, i need something specifically for right side drag

[knotty sun]

then you have probably anchored your rect transform incorrectly

[sand vine]

True, i had my x pivot on 0.5 🤦‍♂️

Thank you very much 🙂

[sacred zenith]

Hey, so 2 players start running at the same time but the window that is active (Clicked on) that player will move faster and further then the other player.

Set editor and parallel sync to focused.
Also added run in background

Still not working any fix?

[lunar python]

my code messiness is scaling very quickly 🔥

[dawn nebula]

nice

[timid depot]

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

public class PotObjectAction : ObjectActionBase
{
    private float waterLevel = 0;
    private GameObject mesh;

    void Start()
    {
        mesh = transform.Find("water").gameObject;
        SetWaterLevel(waterLevel);
    }

    void FixedUpdate()
    {
        print(waterLevel);
        Vector3 cameraPos = Camera.main.transform.position;
        float distance = Vector3.Distance(cameraPos, transform.position);
        if (distance > 50) return;

        Vector3 up = transform.up;
        if (up.y < 0.5f)
        {
            waterLevel = Mathf.Max(0, waterLevel - 0.0005f);
            SetWaterLevel(waterLevel);
        }
    }

    public void SetWaterLevel(float level)
    {
        // -0.019 - 0.336
        float diff = Mathf.Abs(-0.019f - 0.336f);
        mesh.transform.localPosition = new Vector3(0, -0.019f + (diff * level), 0);
        mesh.SetActive(level > 0);

    {
        waterLevel = Mathf.Min(1, waterLevel + 0.005f);
        SetWaterLevel(waterLevel);
    }
}

hey, I got this script, and on fixedupdate it prints two values (like 0.5, 0) and I have no idea how, there is only one pot, only one script

it breaks my script beacuse here

if (up.y < 0.5f)
        {
            waterLevel = Mathf.Max(0, waterLevel - 0.0005f);
            SetWaterLevel(waterLevel);
        }```
it sets waterLevel to 0

[knotty sun]

instead of
print(waterLevel);
use
Debug.Log($"{GetInstanceId()} {waterLevel}");
this will show if there are 2 objects

[timid depot]

ok give me a second

sorry I added script twice

thanks for your help

[dawn nebula]

How often do you guys set component references in the inspector as opposed to using GetComponent in Awake/Start?

[knotty sun]

when ever possible

[dawn nebula]

Same pretty much. Which kinda makes using interfaces rough imo.

[fringe ridge]

Apart from pooling a bunch of squares and placing them as a grid, is there a better way to create a 2d grid with selectable tiles in your opinion?

one way would be to just do calculations on a 2d texture and change the colors based on mouse position

[quaint rock]

there is a grid component you can use with tilemap

you can also just use it on its own if you want as well, so you can take a world position and convert it to a tile position for example

[lunar python]

what is selectable tiles

isn't tile pallete very sufficient (idk)

[hard viper]

tile pallette only works in Unity editor

[fringe ridge]

i just went with pooled cells

actually need them as separate objects

On the other hand i dont know how performance heavy is having 2k+ square objects in a scene

[quaint rock]

you should be fine

if it becomes a problem there are other approaches like generating a mesh to repersent it all as 1 object

as far as selecting them, it would be cheaper to just do the math to convert from a mouse to world coord then to a grid coord then using raycasts and colliders

[fringe ridge]

i did selecting with just basic math, but came up with a better solution, just generated a huge square based on the size of the grid, and then change the position of select square based on the pos in grid.

[slow shale]

Im getting an error trying to save a file: UnauthorizedAccessException: Access denied
File.WriteAllText(Application.dataPath, json);
How do i fix this?

[fringe ridge]

and for keeping track of the cells i have a list of cell objects

[fringe ridge]

is this android?

[slow shale]

regular windows

[rigid island]

why are you writing it to the project folder and not the persistendDataPath

[quaint rock]

Really no runtime code should ever need to hit the dataPath

[slow shale]

You mean this?
File.WriteAllText(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), json);

[quaint rock]

No unity provides a path

Application.persistentDataPath

Look up it's docs

[slow shale]

same error

[rigid island]

well give it a filename

[slow shale]

"C:/Users/Uporabnik/AppData/LocalLow/DefaultCompany/Potapljanje" that is a file name tho, i just checked it exists

[rigid island]

thats not a filename

thats a folder of your project appdata

[slow shale]

oh im stupid

[heady iris]

you need to join it with something else to get a file name

[rigid island]

Path.Combine(Application.persistentDataPath, filename)

[slow shale]

yep, i followed a tutorial and missed the main part, sorry, thanks tho

[lament epoch]

What variable type can I use to read such a json into a unity class?
I cant use Vector2[], float[][] or List<List<float>>
does anyone know how to read it. And yes the Arrays with the numbers are always 2 in length

"test":[
                [
                   12,
                   14
                ],
                [
                   52,
                   57
                ],
                [
                   17,
                   28
                ],
                [
                   25,
                   72
                ],
                [
                   83,
                   23
                ]
             ]

[quaint rock]

pretty sure both float[][] and List<List<float>> will work

though do you want float or int, since the data has no decimals?

[lament epoch]

yea i want float. in the real json its only floats

[rigid island]

or make it a custom class/struct no? then a list of it

[quaint rock]

past that you could do some custom deserilize logic for a custom struct

but without custom logic would need a list of list of float or a 2d array

[late lion]

Unity's serializer doesn't support directly nested arrays/lists. You have to wrap it in a serializable class/struct.

[quaint rock]

well i am making the assuption this is not unitys but like json.net

[rigid island]

public class TestItem
{
    public int thing1 { get; set; }
    public int thing2 { get; set; }
}

 var result = JsonConvert.DeserializeObject<Dictionary<string, List<TestItem>>>(json);

        if (result.TryGetValue("test", out List<TestItem> testList))
        {
            foreach (var testItem in testList)
            {
                Debug.Log($"Item1: {testItem.thing1}, Item2: {testItem.thing1}");
            }
        }```

maybe

[quaint rock]

which i heavily recommend to use over JsonUtility, its a more more complete implementation of json with way less gotchas

[lament epoch]

this is my code

    public GeoJson data;


    [System.Serializable]
    public class GeoJson
    {
        public string type;
        public Feature[] features;

        [System.Serializable]
        public class Feature
        {
            public string type;
            public Geometry geometry;
            
            [System.Serializable]
            public class Geometry
            {
                public string type; 
                public float[][] coordinates; // here
            }
        }
    }

    public void LoadJSON()
    {
        string json = File.ReadAllText(path);
        data = JsonUtility.FromJson<GeoJson>(json);

        //Error object reference not found
        print(data.features[0].geometry.coordinates[0]);
    }

[quaint rock]

dont think that would work

[rigid island]

Ahh ok just doing a quick thing , haven't caffeinated yet so prob is wrong 😅

[quaint rock]

since the inner items also use [] so are not structs

[rigid island]

ahh i see

[quaint rock]

though with json.net you can setup custom logic for how to treat certain types, so you can really bring it into what ever you want if willing to do the extra work

[lament epoch]

ok thanks for your help I will try that

[heady iris]

yeah, which is extremely useful

I have a bunch of "Identifiable" scriptable objects that all have GUIDs stored in them

[quaint rock]

if the List<List<float>> does not work, its because of a limitation in JsonUtility

[heady iris]

I have a converter that serializes them as the GUID and deserializes them by looking the GUID up in a dictionary

yum, GUIDs for breakfast

(maybe these should be base64'd)

[quaint rock]

yeah have done it to just make some simple struct types more condensed too, like something that repersents a range just ends up as "min:max" in json instead of a object

[heady iris]

or maybe I'll just go straight to a binary format. who knows

[quaint rock]

depends on what its for, i have done a lot of binary formats in the past

they can be very useful when you dont always need to read the whole file

[lament epoch]

im not that experienced. I have no idea what you guys are talking about haha

[heady iris]

basically, JsonUtility can only turn some things into JSON, and you can't really customize how it does that

Json.NET (a third party library) can serialize more kinds of things and gives you many more options

It's also just about as easy to work with.

var data = JsonConvert.SerializeObject(obj, Formatting.None, settings);

File.WriteAllText(path, data);

[lament epoch]

ok ill see what i can do but thanks again

[rigid island]

JsonUtility is ok for basic stuff but its total crap for everything else

[rigid island]

Json.net is soo good unity added the package to its PM
https://docs.unity3d.com/Packages/com.unity.nuget.newtonsoft-json@3.0/manual/index.html

[quaint rock]

if using it i would also get
https://github.com/applejag/Newtonsoft.Json-for-Unity.Converters

[heady iris]

now that's a new one

github forgor the page

(it's good now)

[quaint rock]

works on my machine

more or less just provides special converters for a bunch of the unity types to reduce what is written to only what is required and kill a few recursive problems

like vector3 containing other vector3's etc

also adds some other nice converters you can toggle on and off, like one that understands the version type, or have the StringEnumConverter on by default

or DateTime as either unix epoch or iso

[ornate scroll]

somebody help me?
the object not accompanies the character's hand

[west lotus]

Not a code question but you should parent it to the hand bone not the hand mesh

[hoary sparrow]

I have an issue where the part of the code that is supposed to add a control state flag in the "if" statement does nothing.
Removing a state in the "else" works flawlessly, so idk what could be the issue.

[Flags]public enum PlayerControlsState
{
    None = 0,
    Movement = 1,
    Others = 2
};

public delegate void ChangePlayerControlsState(PlayerControlsState state, bool toggleOn = true);
public static event ChangePlayerControlsState OnPlayerControlsStateChanged;
public static void RaisePlayerControlsStateChanged(PlayerControlsState state, bool toggleOn = true)
{
    if(toggleOn)
    {
        UserInput.Instance.CurrentControlsState |= state;
    }
    else
    {
        UserInput.Instance.CurrentControlsState &= ~state;
    }
    

    OnPlayerControlsStateChanged.Invoke(state, toggleOn);
}```

[leaden ice]

[Flags]public enum PlayerControlsState
{
    None = 0,
    Movement = 1,
    Others = 2
};```
This is not right for a flags enum. You need:
```cs
[Flags]public enum PlayerControlsState
{
    None = 0,
    Movement = 1 << 0,
    Others = 1 << 1
};```

although technically those are the same

haha

so maybe that's not the issue

if you have 3 as a third flag value that would be wrong

[hoary sparrow]

yea, I did try the other one b4, and sadly I have the same issue

https://forum.unity.com/threads/enum-flags-everything-option-not-working-with-unsigned-integers.953979/

[leaden ice]

What debugging steps have you taken so far?

[leaden ice]

this is an issue with an unsigned value type which you're not using

[hoary sparrow]

I did take a second look just to be 100% sure I didn't miss a thing ... and of course I messed up the order of operations in a diff spot and now everything works
Thank you

[gray mural]

Hello, I'm storing all raycast targets in the list. Is there any way to catch targets without Raycast target being true ?

PointerEventData eventData = new(EventSystem.current)
{
    position = Input.mousePosition
};

List<RaycastResult> results = new();

EventSystem.current.RaycastAll(eventData, results);

[rigid island]

wouldn't that defeat the whole point of Raycast target?

[gray mural]

it would

I just wanna find Images even with Raycast target set to false

[rigid island]

images from where and why does raycast target need to be off?

[leaden ice]

nope - they are excluded from raycasts

What are you trying to accomplish?

[lethal dragon]

hello, i'm trying to save data in a file for my game using application.persistentdata, but it keeps telling me that there is no authorisation, how do i fix this

[heady iris]

you probably have a bad path

e.g. you did

Application.persistentDataPath + "save.json"

if there's no trailing slash on the path, then you'll get something like

.../CompanyName/ProductNamesave.json

You should use System.IO.Path https://learn.microsoft.com/en-us/dotnet/api/system.io.path?view=net-8.0 -- specifically, the Join method https://learn.microsoft.com/en-us/dotnet/api/system.io.path.join?view=net-8.0 -- to combine path parts together

[lethal dragon]

ive implemented this and its still not working

[heady iris]

then show your code

i have no idea what you've actually written

[leaden ice]

wdym by "it keeps telling me that there is no authorisation"?
Show your code and show the full actual error message

[lethal dragon]

heres my code where path is application.datapersistent and filename is data.game

thats the error

[leaden ice]

Where did you get path from?

[heady iris]

That is not Application.persistentDataPath

[leaden ice]

that path doesn't look like Application.persistentDataPath at all

That looks like possibly Application.dataPath

[lethal dragon]

thats where im actually calling the class filehandler

[heady iris]

that doesn't show us where path comes from at all

[leaden ice]

show the constructor for FileDataHandler

[quaint rock]

why such a complicated setup for just reading a file

[heady iris]

you can just use File.ReadAllText, yeah

I used to use exactly that setup until I realized there's a simpler way

[quaint rock]

its json, so you need all the data at he same time, so might as well just use the simpler command fen mentioned above

the streams are mostly useful for cases where you dont want to read the whole file at once, but since its json you can not take advtange of that

[lethal dragon]

oh okay thank you

[quaint rock]

could be reduced to just the File.ReadAllText followed by the FromJson

[heady iris]

I'm still confused by your persistent data path, though

It's supposed to point into AppData

[quaint rock]

whats it pointing to?

[heady iris]

a folder in the user directory that ain't AppData

[quaint rock]

that looks like its dataPath

[heady iris]

it's like it neatly skipped over AppData/LocalLow/

[quaint rock]

not persistientDataPath

assuming thats where the project files are

[heady iris]

Perhaps there are multiple things creating FileDataHandlers or something

or the code hasn't been saved

[quaint rock]

would assume that

[heady iris]

so unity is running something old

[lethal dragon]

i dont think my unity is fully updated should i update it and also check where the project is saved?

[quaint rock]

this has worked the same for literally every unity version

[heady iris]

log Application.dataPath and Application.persistentDataPath as a sanity check

[quaint rock]

would just make sure you are infact running the new code

[lethal dragon]

okay ill do that

[heady iris]

Okay, it's not trying to open a file in AppData

You must have had Application.dataPath previously

[lethal dragon]

okay, what do i need to do?

[heady iris]

I'd go look in that directory -- AppData/LocalLow/... -- and see if data.game is a folder

You might've accidentally created one at some point

That would cause an "access denied" error when trying to read it, iirc

If you can't find it, you can open the Run dialog and enter this

%AppData%

This will take you to AppData/Roaming, so just go up one level

then go down into LocalLow

[simple egret]

And if in your previous code, at some point you did not use a using statement, and an exception was thrown before the stream could be closed, then Unity might have kept a dangling file handle to it. Restarting Unity might fix it.

[heady iris]

Ah, good point

[quaint rock]

for this case would restart unity and use File.ReadAllText in the future

[heady iris]

yeah, that'll ensure the handle is closed for you

(i hope)

[quaint rock]

but if you do need to open file streams in the future i would always put it in a try/finally

[heady iris]

using cleanly handles that for you (:

[quaint rock]

so the finally clause can close things, or let using dispose it

does using still work on exceptions?

[heady iris]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/statements/using

yep!

[quaint rock]

cool

[heady iris]

You can use both a using statement and a using declaration

[simple egret]

It compiles to a try-finally

[heady iris]

The declarations are particularly slick

using whatever = ThisMustBeDisposed();

[quaint rock]

yeah the inline one is nice

just dispoes on end of function scope

[heady iris]

I use the statement form for IMGUI

using (var _ = new GUILayout.AreaScope(new Rect(10, 10, 300, 300)))
{
  // IMGUI in here
}

[quaint rock]

though all of this requires disposers, what i really like was Go's defer statement lets you queue up any function including a closure to execute on exiting method scope, but before return

[leaden ice]

defer is magic and so much more flexible/useful than try/catch

[quaint rock]

@leaden ice familar with Go, or a other langauge that uses defers

[leaden ice]

I use Go professionally

[quaint rock]

nice, its amung my favourite languages to work in at the moment

[gray mural]

I have implemented the logic for stretching and dragging panels. The stretching shouldn't work if there's a UI Object over the Object with those scripts. That's why I am checking whether the "stretchable" or "draggable" object equals to the first raycast target object. If not, stretching or dragging won't be able

Oh, and now I have a question for myself. Why would I even need to find those objects without raycast target?

[leaden ice]

do all your dragging etc with the event system and you get this behavior for free

you're writing a lot of code to basically recreate the event system's default behavior

It has built in drag/drop support

[gray mural]

No, it's not gonna work out

[gray mural]

you're right, it doesn't work with stretching threshold though

[leaden ice]

I bet it would work fine

what does stretching threshold mean?

[gray mural]

stretching threshold means that stretching may start in the selected range from panels' borders

[leaden ice]

So you're saying event system won't work because you want to be able to start the drag from outside the border?

[gray mural]

Yes, I suppose so

[quaint rock]

you can manually raycast from the event system

[gray mural]

so cursor is gonna be activated and it doesn't care wether there are some other objects nearer to the camera

[gray mural]

Sorry, what do you mean?

[quaint rock]

so you could start it based on what ever input you want to start the drag, and just manually cast looking for hits

[gray mural]

stretching?

I have implemented that already, so that's no problem

[lethal dragon]

i've spent a while looking for appdata\locallow and i can't find it is it supposed to be there?

[heady iris]

where are you looking?

LocalLow is inside of the AppData folder.

I showed you how to open AppData/Roaming

I think AppData is hidden by default

so you wouldn't see in your user directory

[quaint rock]

it shows you the exact path, just like log Application.persistentDataPath and copy that into a file browser

[heady iris]

that too

[gray mural]

So my question was redundant from the start, because I haven't mentioned it was already solved even before I asked it.
I created a TargetBlock script for objects with Raycast Target checked. If TargetBlock.block is false, the object shouldn't block my StretchablePanel even with having Raycast Target checked.

[quaint rock]

i often end up making a some menu items like this

public static class PersistentDataMenu {
    [MenuItem("Persistent Data/Clear Persistent Data Path")]
    public static void ClearPersistentDataPath() {
        var directory = new DirectoryInfo(Application.persistentDataPath);

        foreach (FileInfo file in directory.GetFiles()) {
            file.Delete();
        }

        foreach (var dir in directory.GetDirectories()) {
            dir.Delete(true);
        }
        
        PlayerPrefs.DeleteAll();
        PlayerPrefs.Save();
    }

    [MenuItem("Persistent Data/Reveal Persistent Data Path")]
    public static void RevealPersistentDataPath() {
        EditorUtility.RevealInFinder(Application.persistentDataPath);
    }
}

so i can quickly go to the persistentDataPath and clear it as needed

[gray mural]

I haven't mentioned that, because I thought I should've used it for objects without Raycast Target

[lethal dragon]

yeah i found it i was just being dumb sorry theres no data.game file there

[quaint rock]

so you have not executed the code to create it yet, since fixing the path

[heady iris]

your code checks if File.Exists returns true, so it's gotta be seeing something

[lethal dragon]

the error is still showing

is there any problem with my save code

[knotty sun]

yes, obviously

[heady iris]

there you go

this creates a folder named data.game

[heady iris]

so there is a folder, isn't there?

[lethal dragon]

wdym

[heady iris]

I mean exactly what I wrote. There's a folder named data.game in AppData/LocalLow/DefaultCompany/Shooter Game/, isn't there?

[lethal dragon]

yes there is

[heady iris]

hence why I asked for this

don't create a directory with fullPath.

[leaden ice]

string dir = Path.GetDirectoryName(fullPath);
Directory.CreateDirectory(dir);
File.WriteAllText(fullPath, jsonString);

It's ok to do this unconditionally

it will do the right thing

[heady iris]

you can use Directory.Exists if you really want to

but yes, it's fine if you create a directory that's already there

[knotty sun]

tbh, the complete code is nonesense

[heady iris]

the rest can be completely replaced with File.WriteAllText

the overall logic is...wrong, though, yes

you're checking if a save file already exists

if it does, you create a directory

if it doesn't, you try to write a save file

but since you created a directory at fullPath, File.Exists will always return false and you'll just try to create a directory again

[heady iris]

this is all you need.

    static void Serialize<T>(T obj, string path, bool onlyCreate)
    {
        var directory = Path.GetDirectoryName(path);

        if (!Directory.Exists(directory))
            Directory.CreateDirectory(directory);

        if (onlyCreate && File.Exists(path))
            return;

        var data = JsonConvert.SerializeObject(obj, Formatting.None, settings);

        File.WriteAllText(path, data);
    }

here's my Serialize function I use for everything

I actually just updated that code this morning, hah

[leaden ice]

You can remove the if check here too:

if (!Directory.Exists(directory))
            Directory.CreateDirectory(directory);```

[heady iris]

I was thinking about that

went and looked it up and it's like mkdir -p

[leaden ice]

yep

[heady iris]

just didn't actually change it

I use onlyCreate to generate a settings file on first launch

[knotty sun]

then you could have the decency to give it a false default value, lol

[heady iris]

this method is private; you call public Serialize and SerializeIfMissing methods.

they have a params argument, so no default arg for me

i build the path out of one or more strings

I did flip-flop on that several times, though (:

[lethal dragon]

is this still wrong?

[heady iris]

this is still very wrong, yes

[lethal dragon]

oh god

[heady iris]

you're checking if a file exists

pay attention to what you're doing

you don't need to check anything at all. just use Directory.CreateDirectory(dir); to ensure that all of the directories on the path exist

[lethal dragon]

oh

okay

[heady iris]

The rest looks reasonable enough. You will want a way to indicate to the player that saving failed, though.

[lethal dragon]

the saving still fails

[knotty sun]

he said PAY ATTENTION

[lethal dragon]

im trying

[knotty sun]

look at the file you are trying to write

[heady iris]

you can't just use random variables

each one has a very specific meaning

dir is the directories leading up to where you're trying to write this file

[lethal dragon]

please im only in school this is for my coursework i started learning c# a couple months ago, what do i need to do instead here

[knotty sun]

think

this is the problem with spoonfeeding @heady iris

[heady iris]

this problem has very little to do with C#

and mostly to do with...reading. look at what you are doing

explain to yourself exactly what each line does and why you couldn't change it to other variables or other functions

[lethal dragon]

i really don't know where the error is i'm sorry im really struggling to see what i'm doing that's wrong

[heady iris]

There are only five meaningful lines of code in that function.

[knotty sun]

ask yourself which variable contains the directory and file name you want to write

[heady iris]

Don't just stare at it.

[heady iris]

I'm not joking. Explain what each line does out loud.

[quaint rock]

its just about attention to detail, regardless of if you stick with programming or not, its a good skill to have

[heady iris]

prove to yourself that every variable and every function call makes sense

[quaint rock]

think about what each line does, and what each variable repersents

[stuck lotus]

Hello, has anyone here worked with a graphql database by any chance?

[knotty sun]

yes, it's absolutley terrible

[stuck lotus]

at this point anything is better than what i am going through right now trust

[stuck lotus]

i seem to get html back for some reason from my requests

[knotty sun]

should return json or xml

[stuck lotus]

it should return json

[knotty sun]

then the end points have not been configured correctly

[stuck lotus]

they are as i have the same project on react and it works fine, i can also see it on the playground it works fine

[knotty sun]

that makes no sense, end points do not respond differently depending on the user agent

[stuck lotus]

i know right

[knotty sun]

then you need to question your query

graphql queries are notoriously fickle

[stuck lotus]

yh i am unfortunately very aware of that

[stuck lotus]

what do you mean by this?

[knotty sun]

look very carefully at how you have composed your query, one simple mistake can invalidate the whole query, the joys of json formatting

[stuck lotus]

again its correct i can see it in the playground

[knotty sun]

but really this is outside of the scope of a Unity server

[simple egret]

Maybe you're not passing the correct Accept header? Or no header at all

[stuck lotus]

well i am only having problems on unity thats why i came here but i do understand that

[knotty sun]

make a console program using HTTP Client that works, then implement the same thing in Unity

[stuck lotus]

just so we are clear are you asking me to make another program outside of unity that basically fetches this data?
and then try to rewrite the code used for that in unity?

[knotty sun]

what I am saying is take Unity out of the equation. Make something that works first, then transfer that to Unity

[stuck lotus]

i have used either

www.SetRequestHeader("Content-Type", "application/json");

or
www.SetRequestHeader("Accept", "application/json")

[knotty sun]

exactly, I said use Http Client

[stuck lotus]

i do have something that works i have a react project that fully works, we need to transfer everything to unity

[knotty sun]

but react is not C#

[stuck lotus]

i know that but surely that shouldnt really matter as its just a request right?

[knotty sun]

yes, it matters

'just a request' how to say 'I know nothing about http programming'

[simple egret]

If you get HTML from the endpoint then save it to a file, and read it. It might contain essential information

Inspect the HTTP return code as well

[knotty sun]

almost definitely the html is an explanation of the http error code, probably 403, 404 or 500

[stuck lotus]

returns 200 so i know it works

[knotty sun]

nah

[sharp agate]

i don't know where can i ask this

but i want to know why i've created an Multiple Sprite

of 32x32

and Unity imports the sprite bad

[rigid island]

turn off filtering and compression

[sharp agate]

Oh thanks

[rigid island]

also not a code question #💻┃unity-talk

[sharp agate]

is just that

[stuck lotus]

one sec

[sharp agate]

Sorry

i didn't know

thanks

[rigid island]

u good np 🙂

[stuck lotus]

ok anyway i will see what i can find in the most remote repos just sort of glad to know its hard to work with in general makes me feel a bit less stupid

[knotty sun]

is that supposed to be a valid query?

[stuck lotus]

yh

[simple egret]

Post the HTML/XML you get when querying from Unity

Alternatively you can open your browser's dev tools and inspect network traffic there

[stuck lotus]

its a lot of code its literally all html css so will just post this

[knotty sun]

as this is a code channel you could actually just share the code you are using

[stuck lotus]

fair enough give me a sec

[simple egret]

Not enough info, the useful stuff will be in the body, after the style. Save to a file and post it here !code

that is not the graphql rest api

[simple egret]

Yeah that's your playground most likely lol

Seeing the <title> element

The playground itself will request an endpoint for you, when you hit "Send" or whatever, your code needs to hit that too

You get an HTTP 200 because the request is technically successfull, it loads the playground front-end page you showed above

[stuck lotus]

ok so this is the "HTML and CSS" https://gdl.space/lebuxufivo.xml

and this is for the func i am using
https://gdl.space/lukunukule.cs

[simple egret]

Yes your HTML seems like it's the source of this page ^

[stuck lotus]

yes

[simple egret]

It's not how it works

The GraphQL server (?) exposes an API endpoint and a playground for convenience - you need to request the API, not the playground

[knotty sun]

your query is totally misformed

[stuck lotus]

is it ok if i share quick screenshots of code or is that against the rules?

[knotty sun]

sure

[simple egret]

I see your code, it's the value of graphqlEndpoint that's incorrect

[stuck lotus]

this is on the react end this works fine

[knotty sun]

this is an example of a correct graphql query issued via c# httpclient

                string qry = @"{ ""query"": ""{ Student (id:"+pid+
                @") { id registrationForm { displayShortName } firstName lastName firstEntryDate leavingDate curriculumGrade { code } " +
                ((askForSiblings) ? @" siblings { id } " : " ") +
                @" eligibilityRecords { displayName startDate endDate } postalAddresses { displayName }  " +
                @" mealChoices { appliesMonday appliesTuesday appliesWednesday appliesThursday appliesFriday appliesSaturday appliesSunday " +
                @" mealProvision { displayName isSchoolHotMeal isSchoolLightMeal isSchoolPackedMeal isStudentPackedMeal } } " +
                @" } } "" } ";

there is a big difference with react

[simple egret]

If the query was incorrect it would have not returned HTTP 200

[knotty sun]

it did not see the query

[simple egret]

My guess is that the URL is not the API endpoint one, and it happily discards the body when you access it

Fix the URL, then once you start getting HTTP 400s, fix the query

[knotty sun]

agreed

[stuck lotus]

ok i will see what i can do, thanks anyway for the time it was appreciated

[knotty sun]

[zinc knot]

https://gdl.space/kibimapizi.cpp hi how would i slow down the coroutine or prevent it from doing my whole array all at once, since it goes straight to wave 5, i used a boolean but it doesnt delay it at all

[cosmic rain]

Well, you're waiting for 0 seconds, so what do you expect?🤷‍♂️

[zinc knot]

even when i wait for longer it doesnt change much

also when i make it longer, it goes straight to wave 5 and skips the first entirely

[cosmic rain]

You're also starting the coroutine in update. It's likely that you have several instances running.

Do proper debugging to see what's happening.

[zinc knot]

whats happening is it goes straight to 5, seems like its running in the background

[cosmic rain]

How are you debugging? What made you come to this conclusion?

[zinc knot]

I’m debugging it by checking how many times the coroutine is called

Sorry

I mean what wave it’s on

So it starts from wave 0 and it goes all the way to 5 even with a. Time delay

[cosmic rain]

How? Debug logs?

[zinc knot]

Yeah using a debug log I check what wave it is before and after the spawn function is called

[cosmic rain]

Share the updated code with the logs

[zinc knot]

It goes from 0, to the max in my array, 5 instantly

https://gdl.space/yapihuvuso.cpp

here

[cosmic rain]

From what I can see, it would wait 3 sec after the game start and then go through a wave each frame.

So basically all 5 waves would be done in a few frames.

[zinc knot]

So where can I put the delay instead?

[cosmic rain]

How exactly do you want it to work? Just spawn waves with some interval?

[zinc knot]

like spawn the waves one by one instead of skipping all the way to the 5th

[cosmic rain]

They should be all spawned one by one. Just in a few frames.

[zinc knot]

thats not whats happening though

[cosmic rain]

Then debug that.

[cosmic rain]

WaveCounter.instance.WaveCount seems to be what devices the wave index.

[zinc knot]

yes

[cosmic rain]

You want to debug that before the spawning logic.

[zinc knot]

i have that debugged

[cosmic rain]

Not in update

[zinc knot]

in the thing that spawns my stuff?

[cosmic rain]

Yes

[zinc knot]

ah yeah

okay i did that

whats happening is all the waves are spawned immediately all at once

[cosmic rain]

So they do as I said?

[zinc knot]

yeah

how would i delay it so they dont all spawn at once?

[cosmic rain]

If you just want a delay between the waves, get rid of the coroutine and just use a timer in update.

[zinc knot]

nvm i fixed it lol

lemme double check tho

@cosmic rain thanks for the help, what i changed was making the isSpawning boolean to true before the delay is started

[lone narwhal]

Hello, i have been having trouble with coding.

In one part of my game, there's a barrier blocking a part of the map which you need the flashlight and yeah that part is working. The problem is that the message displaying telling you to get the flashlight is not appearing. Can someone help me with this?

[cosmic rain]

I don't think that fixes the underlying issue. Just conceals it.

[soft shard]

Whats the code you are using and how do you trigger this text display?

[zinc knot]

idk but the waves do spawn well now, its a school project and ive only been doing unity like for 2-3 weeks lol

[nimble cairn]

Hi guys bit of an interesting question here.

I have a script that generates a random HSL color for my bullets. (cool rainbow bullets)

This script then uses a SRGB difference algorithm I wrote to ensure that there is a noticeable degree of variation between each bullet's color prior to spawn to keep things interesting.

However, I'm still not satisfied with the contrast of the bullet's color and the level, and sometimes there's the issue of the algorithm not understanding that "blue" and "light blue" are still blue even though they pass the sRGB threshold test.

I've thought about having an array, with 256 unique websafe colors to ensure contrast between the level and the bullets, and as well as this, if I order the colors in a JSON file, following a ROYGBIV (red, orange yellow...) rainbow I can calculate different colors by just adding X steps to the JSON array instead of these expensive color algorithms.

My question is:

• Should I have the JSON file with all the shades of color be on my "game manager" gameObject and have each bullet reference a color that way OR:

• Include the external JSON file on each bullet and have internal calculations prior to spawning.

• What would be the most efficient?

• Is there anything I should worry about if I include a file with cross platform development?

• Do you have any suggestions for a more efficient approach whilst achieving my above mentioned goals with variation and contrast in mind?

[lone narwhal]

can i just send the code i have?

[cosmic rain]

It would make sense to load the json once into an array in a game manager or similar manager class. In fact it might make sense to create a bullet manager that would handle all the logic, like keeping track of what color was used last, etc...

Not sure what you mean by a "file with cross platform development".

[nimble cairn]

I agree that seems to be the best approach.

Well I'm not sure if I want the array of colors to be an external JSON file, or just have a hardcoded array in the manager class.

If I do pick an external file, I'm worried that there might be some issues with how the file is included on linux.

[cosmic rain]

You could just have is a serialized field on the manager. Up to you.

[cosmic rain]

Why would there be an issue with how it's included? If it's part of the build, there shouldn't be any problem at all.

[nimble cairn]

Really? Cool! Thanks again!

I just wasn't sure if I had to chown or chmod the file somehow to ensure permissions did not break.

[soft shard]

Looks like your textActive bool is almost always false, the only time it ever becomes true, is if your lanterna reference is not active, then on E input, you destroy the object containing your BarreiraInvisivel script, so your textScript is likely always going to be false in best case, and null in worst case

[lone narwhal]

if thats a curl command which i think it is because of the -d it should be pretty simple to do with pretty much any http client

[soft shard]

Assign the bool your checking with, so its not always false, for example you seem to be also using another private bool jogadorPodePassar and your using that to handle checking your input, instead of your public bool

like i said, i've spent over 8:30 hours documenting and trying different stuff out, nothing clicks

[soft shard]

The code that you wrote? You linked it, I didnt mention anything that isnt already in your scripts

you just need to figure out how to serialize the body, after that its just add the 2 headers and post

[lone narwhal]

i mean, the new part of the code that you said to change

[fathom sinew]

have you not done similar stuff before? i just want a clue.

[soft shard]

Well, look over your BarreiraInvisivel script and see what you are doing with your jogadorPodePassar variable and textActive, knowing that only textActive is accessible outside of your class, and jogadorPodePassar is not, only being used inside your class

[quaint rock]

https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequest.Post.html
more or less follow the example here, but after the post before the SendWebRequest use SetRequestHeader on what post returns to set the bearer token

[fickle lichen]

async Awaitable TimerStart(float startPoint)
{
    while(true)
    {
        Debug.Log(Time.time - startPoint);
        await Awaitable.WaitForSecondsAsync(1, destroyCancellationToken);
    }
}
```Hey, does this error mean something is wrong or just an info it has been canceled correctly and everything is fine?

[quartz folio]

It means it was cancelled. You should try catch that specific exception at the point where you want to handle it

[fickle lichen]

try
{
    await Awaitable.WaitForSecondsAsync(1, destroyCancellationToken);
}
catch(OperationCanceledException e)
{
    Debug.Log("Coroutine canceled successfully: " + e.Message);
}
catch(Exception e)
{
    Debug.LogError(e.Message);
}
```Well, I did put a try catch but I'm not just sure if this really is an error and should I do something with it? Or is it fine as it is?

[quartz folio]

It's probably pointless to catch it there unless you want to continue execution from there?

And no, you generally just catch it and do nothing with the exception, as it's purpose is entirely flow control

[fickle lichen]

No, it seems this exception is being thrown only when I stop the game

[quartz folio]

Yes, because the object is destroyed then, otherwise it would continue running the async function into edit mode

you should handle it at the top of the async stack, where you start awaiting

so you can cancel out of the logic entirely

[fickle lichen]

Aight, so it's all good even though it shows me "OperationCanceledException" which technically is an error but for us is fine?

[fickle lichen]

Does it matter? Can I catch it inside the method or should I catch when I call the async method?

[quartz folio]

it's your code, I told you what I would do

[cosmic rain]

An error is generally telling you that something went wrong. When an awaitable did not finish it's execution due to cancellation, it's something went wrong and you need to handle it.

[fickle lichen]

Aight

[quartz folio]

OperationCancelledException is not communicating wrong, it's communicating cancellation, nothing more

[fickle lichen]

It didn't finish execution because it's never going to finish it it's rather going infinitely until I stop the game

I would said it's while(true)

round value is not going to reach 3 anyway in my code

[fickle lichen]

Just edited this code to show what I mean

[cosmic rain]

I wonder why it's different from the C# tasks though. I don't think there's an error when you cancel a task via a cancellation token.🤔

[quartz folio]

There is

[cosmic rain]

Hmmm... Don't remember it ever being thrown when I canceled tasks.

[quartz folio]

https://learn.microsoft.com/en-us/dotnet/standard/parallel-programming/task-cancellation

By throwing an OperationCanceledException and passing it the token on which cancellation was requested. The preferred way to perform is to use the ThrowIfCancellationRequested method. A task that's canceled in this way transitions to the Canceled state, which the calling code can use to verify that the task responded to its cancellation request.

It depends entirely if you choose to use the cancellation token this way

and Unity has chosen to do that in their awaitable implementation so you don't have to additionally check and handle it

it's very standard though

[cosmic rain]

Ah, so it's users choice how to cancel it.

I see

[quartz folio]

Backing out of the whole async stack when the game ends would be a pain in the ass without the exception

I know because I've tried it before lol

[fickle lichen]

async Awaitable TimerStart(float startPoint)
{

```Well, that's how I've made it and how it looks like now, during game play, once called it starts counting and showing time in the game and keeps counting infinitely until the game is stopped, so I believe this try catch is all good and no issue here

[quartz folio]

I really have no idea why you would catch in the inner loop

[cosmic rain]

I usually don't have long chains of a async operations, so it was easy to just return from the sync method on cancellation. But it does make sense.

[fickle lichen]

Well, this exception is going to be thrown at the end of the game, it appears only and every time I stop the play mode

[quartz folio]

that doesn't justify anything

why are you slapping yourself in the face?

well it's a nice day outside

[fickle lichen]

if(keyboard.rightArrowKey.wasPressedThisFrame)
{
    await PlaySound(przejscie);

    if(++round == 1)
        await TimerStart(Time.time);
}
```So you're saying I'm supposed to do try-catch where I call this async method? Here?

TimerStart()

[plucky karma]

This sounds like you're running async code in your editor... I'm a bit lost on what you're trying tro achieve in your TimerStart method. Was there anything wrong with using Time.deltaTime?

[fickle lichen]

No, everything works fine but the only thing is when I exit play mode I get this error #archived-code-general message

[quartz folio]

If that's the top of the async stack, sure, catch it there.
You can also catch it outside of the loop. There's just no reason to catch it inside the loop, just to have it potentially go around the loop again

[fickle lichen]

I think so? I call it inside async void Update()

Alright thanks for your help!

[cosmic rain]

Async update🙀

[fickle lichen]

Actually I just thought I can make some sort of kill switch and instead of while(true) do something like while(!isEscaping) so when user exits the game the bool value stops the loop and finishes the async method

[plucky karma]

You are running an infinity loops with no breaks. Unity won't close play mode unless it breaks your loop somehow.

[fickle lichen]

Won't close play mode? As I said it's all working fine

[plucky karma]

I don't know what's worst... That this update is async, or it's returning void from async method.

[quartz folio]

The structure of this code is set up to fail because there's variables being relied on to increment and they're not even incremented in the same function that relies on it

Returning void from async is fine in Unity at the top of the async call

Because Unity handles exceptions differently than normal .NET programs

[rigid island]

unity's awake method is a void async version 😬

[plucky karma]

I use IEnumerator for Awake/Start methods

[plucky karma]

I can't remember, but won't this suppress exception thrown inside async void methods?

[quartz folio]

No, because Unity catches it

As long as Task/Awaitable-returning async methods are awaited no exceptions should be eaten

[rigid island]

half of Unity's UGS APIs are async Task so gotta use that :\

[zinc knot]

anyone know what these errors are?

[cosmic rain]

Editor API is not included in the build. When you try to build with code that relies on it, it would fail.

[rigid island]

also don't crosspost @zinc knot you already asked in #💻┃code-beginner

Google tutorials.

i'll check that

[rancid frost]

I dont know where to ask this,
but can someone tell me how maps like this are usually created?

Is a tile system in place? Does it use unity terrain?

The image is from a game called Broken Arrow.

Thanks

[latent latch]

man that map is about flat as florida

can look into unity's terrain tool. It's pretty basic but it gets the job done

[fair mural]

what would be the optimal solution to anchoring a point to a specific region of a perspective camera using a varying FOV? here's a couple photos based on what we have. the gun camera has an FOV of 75, hence when I make the normal camera FOV 75, it is positioned properly. however, it gets displaced because of the gun cam still being 75, thus changing the position of the origin of the bullet trail in the perspective cam. im assuming i have to use tan in this, but im not sure how. any insight?

75 FOV

120 FOV

[long scarab]

in my game i have a levelManager script that handles values like wave, lives, etc and passes them to an additive UI scene to display it on the HUD. would i have any issues using a scriptableObject as a data middleman here where levelManager updates the values every frame and then a UIManager script in the other scene grabs those values and updates the UI?

[topaz pond]

anyone know how to unlock these folders?

i cant access em

[mild coyote]

assuming you are using two camera, how about using guncamera.worldtoviewportpoint then use the return value to camera.viewporttoworldpoint?

[fair mural]

yeah I thought of that, but what about depth, isnt that a vector2?

because perceptual distance also varies with fov

[mild coyote]

it's vector3, with z is the distance from camera

oh. i was thinking about screenspace

Hi. I'm building and then trying to install two different apps from one unity project on android. But my phone still detects them as "same app" and making an update instead. How does android differentiate one app from another and how to fix my problem?

[west lotus]

With the bundle identifier

You need to change it to com.company.app1 and then for the scond build do like com.company.app2

[thin kernel]

thank you

When doing an asynchronous load scene, can I make it only prepare the load, then I make it load ?

By default when doing AsyncLoad it will directly load when finished

hey dude just wanted to so that i think i sorted it out, had a good look at many repos and in the end i decided to go for this one https://github.com/NavidK0/SimpleGraphQL-For-Unity
the reason why i didnt want to use packages such as the above is becuase most of them dont support subscriptions on webgl builds but i have found a work around that. i still dont get some of the data but i do get most of it so hopefully all should be good from now on and again thanks for the time you spent trying to help me it was appriciated

[knotty sun]

Good to hear. Subscriptions for WebGL should not be a big problem, just need an Emscripten .jslib to act as a passthrough from the browser JS to Unity.
As this library looks to be abandonware I may incorporate all of parts of it into my SQL for Unity system as an addon feature

[stuck lotus]

i am not really allowed to disclose much but i am working with a library that connects to another engine that came out literally 1 week ago and i am the only one debugging/testing, this lib i am using does have subscription and queries function for graphql as that is sort of how that engine works but its really not the best, but i have managed to get the subscriptions to work through that lib and then i will use general queries through https://github.com/NavidK0/SimpleGraphQL-For-Unity here, bit messy but when you are the first in this sort of things its just how it is. i hope this gives a bit more context to the whole thing i have been through

[knotty sun]

Best of luck with it, one question though, how is the performance? That has always been my biggest problem with any kind of NoSQL integration into game dev

[stuck lotus]

i have never had any issues with speed on the react end even with 1000+ entities getting updated, but i have to yet migrate everything to unity i am still doing basic tests to see if all the basic functions work but i will let you know

[knotty sun]

please do

[woven veldt]

Hi, so I have this struct which is holding data for my conveyors. However I need to keep a float3 array for different paths. Can I use native arrays for this or would it result in a data leak? I also get an error which says Unity.Collections.LowLevel.Unsafe.DisposableSentinel, which is neither primitave nor unsafe.

[knotty sun]

Native data is unmanaged data so you are responsible for disposing of it, not doing so will result in memory leaks

[quartz folio]

You should probably be asking in #1062393052863414313 as you are using ECS

Hi I'm implementing basic dragging and dropping of UI elements. What is the 'best practice' way of checking if the Collision2D being overlapped contains a specific component. Running GetComponent<>() on every collision frame seems horribly inefficient, and using tags feels like jank.

[lyric moon]

uh.. what?

this line has the issue

im setting my action.. to a void that matches the parameters required

what tf is this error

oh i think eventExposer was null

[lyric moon]

a nullreferenceexception wouldve made that clearer wtf is this one

[swift cobalt]

Hi everyone. I have a strange issue. I got a coroutine Invoking an event, but the code after the Invocation isnt executed. This is my code. Any Help would be much aprreciated ```cs private IEnumerator CameraTransition(Material mat, MovementType movement)
{
cameraAnimator.SetTrigger("FadeOut");
LocationManager.Instance.PointChange?.Invoke(movement);
yield return new WaitForSeconds(1);
RenderSettings.skybox = mat;
cameraAnimator.SetTrigger("FadeIn");

}```

[knotty sun]

I would guess an exception is being thrown

[mellow sigil]

Either the coroutine isn't started correctly, or the object that started it is destroyed during the one second it pauses

[swift cobalt]

No not at all. No error appears. All the execution of the project after that is working fine, but the code in coroutine after the invocation isnt working

[knotty sun]

debug it

[swift cobalt]

the coroutine is called with StartCoroutine and there is no Destruction of anything.

I have debuged it and I ve set a break point in the Invocation. The next step just skips the code after the invocation

[sacred plaza]

And the MonoBehavior the coroutine is associated with isn't modified in any way? Disabled or such?

[swift cobalt]

No

[mellow sigil]

Show full code

[swift cobalt]

Aaaah

this might be the issue

I sorted it out. Thank you all for your valuable feedback @mellow sigil @sacred plaza @knotty sun

How do I export data (here .zip) during runtime?
I want that my bugtesting exports the persistend data I am saving in userdata. They should be able to save it anywhere on the iPad so they can send me it in discord

[knotty sun]

you can easily create a zip file using
https://learn.microsoft.com/en-us/dotnet/api/system.io.compression.zipfile?view=net-8.0
however you can only save to Application.persistentDataPath, not 'anywhere'

[bitter saffron]

yeah yeah I am already saving json and zipping the folders. What I want is that the users can send me zip, export it out of persistent data

Guess I need a file browser or some sort

[knotty sun]

that's easy to make with the UIToolkit TreeView

[crisp scarab]

I have a concern regarding optimization
Context:
my game have rooms procedurally generated, the rooms floor and walls(no roof) are made of multiple individual cubes. the camera is orthogonal top-down rotating around the player as center point
I have 4 directions (normalized) the camera can rotate to defined as
"North" is (1,1 )
"South" is (-1,-1 )
"East" is (-1,1)
"West" is (1,-1)
When the camera is facing from the north direction, i want to hide the north walls of every room, meaning i have to loop the collection to SetActive(false) each cube. To separate the walls of each room based on the cardinal direction, i placed the "cardinal axis" (0,0) on the center of my rooms and normalize the position of each cube, using the wall.height to determine the corners directions.

Issue:
The issue is regarding which data structure would be the best performance wise in this case, the most direct approach would be to have 4 different arrays such as:

int wallArea= (averageWall.height * averageWall.length) * (RoomList.Count*4) 
Cube[] NorthWalls= new Cube[wallArea];
Cube[] SouthWalls= new Cube[wallArea];
Cube[] EasWalls= new Cube[wallArea];
Cube[] WestWalls= new Cube[wallArea];

but because some walls will be bigger than others, the arrays might have empty spaces, there's also matrix, or dictionary approach:

directionMap = new Dictionary<string, Cube>();
// and then to add the cubes would be something like this. In this case, checkDirection would return a string of the cube direction like "North", "South", etc.
void PlaceWallCubes(Vector2Int location, Material material) {
for(int i = 1; i < wall.heigth; i++){
        GameObject go = Instantiate(cubePrefab, new Vector3(location.x, i, location.y),     Quaternion.identity);
       
       directionMap.Add(CheckDirection(go),go);

[sacred plaza]

If you only change whether a wall is active or not when the camera is rotated, you can pretty safety iterate over every wall in the game when the camera has been rotated for a certain threshold for a really large number of walls.

But, if you want a more optimised method you could build an index ahead of time. Which is just four arrays referencing the walls. I am not entirely sure why the size of the walls matter, I'd expect each wall segment for a cardinal direction you'd want to hide to be part of some distinct object hierarchy (which is just one reference) so you'd use that.

[fervent furnace]

why your array can have "empty space"

btw i think you will get "duplicate key exception" (i forgot the name) if you use dictionary

[knotty sun]

you dont need any of this, let each wall 'think' for itself

[crisp scarab]

wdym "think" for itself? can you explain more?

[knotty sun]

let each wall subscribe to an event, say CameraChange.
when the camera changes invoke the event, then each wall can decide whether it should be visible or not and take the appropriate action

[west lotus]

Thats far from optimal imho. Depends on how many walls he has

[knotty sun]

the ammout of processing is identical if not less

[crisp scarab]

the area is to have a precise array lenght because the walls are made of cubes, i'm adding the cubes to the arrays, not the object "wall"
