We use TeamCity (Unity cloud is no help as we support a lot of platforms and many engines - not just unity), in most cases I'd say the work isn't usually worth it for automatic testing. But we have PS5, Xbox, VR, AR, web, desktop games and projects. So we need a lot more QA on unity releases than a normal company

[peak pivot]

I am checking if certain methods are not stripped away.

[polar marten]

why?

[peak pivot]

Because the project I'm working on uses a library that doesn't directly call these methods. So if stripping is set to high they are removed.

[west sparrow]

We try to not use Unity services for anything though, they accidentally disabled our license keys once and it shut down a major project the day a hospital release was needed. That kind of ended us depending on Unity for anything

[hexed oak]

Yeah I'll likely end up migrating away from jenkins for building stuff, then some kind of VM or docker deployment to actually run the built applications

Oh my god, you build hospital software?

[polar marten]

okay. so your saying the y of your xy problem is

[peak pivot]

Causing exceptions at runtime. I want to set stripping to high since it removes a lot of memory usage.

[west sparrow]

Yup! Stroke, dementia care and autism 🙂

[polar marten]

y: "sometimes, some methods are stripped away, and i would like them not to be"

is that correct?

are you familiar with the [Preserve] attribute?

[peak pivot]

The question I have is. Given a System.Type can I somehow get which line that class is defined?

[west sparrow]

Hense the complex as heck build server and QA requirements 😄

[polar marten]

are you familiar with the [Preserve] attribute?

[peak pivot]

Yes, the code I'm writing is checking if the preserve attribute is on those methods.

[hexed oak]

Yeah I've heard of teamcity and the pricing seems pretty high for our needs

[west sparrow]

At a past company we had a great experience with Jenkins though.

[peak pivot]

what I have now generates a list of these types but in type names, rather than file/linenumber

[polar marten]

you can use link.xml to achieve this too

what you are doing doesn't make sense.

[west sparrow]

Team city does have a pretty good free tier now though

[peak pivot]

It's basically a Lint >_>

I feel it make sense

[polar marten]

anyway, no, you cannot get the line number, sorry. it will take you longer to verify this stuff and write the linter than it would be to fix it once

your library sounds buggy

[hexed oak]

I'll definitely have to try the free tier on some personal stuff. I like the on prem options when I can get them

[polar marten]

it should call the methods directly

[peak pivot]

Oh yes, I very much don't like it. But it's a 5 year old project and I joined it late.

[polar marten]

you are developing a video game and you're trying to use a sophisticated feature, code stripping. you should spend the time fixing the library

well

no one is going to use the linter but you

so think this one through critically

[peak pivot]

They already have unit tests running

The plan is to run it inside a unit test to conform with the current workflow.

[polar marten]

it's hard for me to be helpful. you're asking how to directly reference methods by not directly referencing them. you have to fix the library

it is a colossal waste of time to write a linter for this. fix the library

[peak pivot]

Yeah, I understand and if I had any say in it that library wouldn't be used.

[polar marten]

if you can already mechanistically determine which methods you need, you can generate a link.xml instead*

it doesn't make sense to author a linter. just generate the link.xml

[peak pivot]

Can I do that for constructors as well?

with arbitary arguments?

[polar marten]

yes

why wouldn't you be able to?

anyway, you haven't really gotten to the y of your xy problem

[pine jungle]

Assets\Scrips\SelectionManager.cs(9,5): error CS0246: The type or namespace name 'Text' could not be found (are you missing a using directive or an assembly reference?)

[polar marten]

what are you trying to do?

[pine jungle]

those shamone now how to fix this

[polar marten]

what is going on in the game?

[leaden ice]

well you're missing a using directive, like it says. #💻┃code-beginner

[pine jungle]

i have it but the place wear i should but it those not show

[potent sleet]

Text Is the the UI namespace

[swift falcon]

Is there a way to include the detail meshes into the terrain heightmap? For example, if I paint a bunch of 1x1x1 cubes onto a flat terrain, there should be a bunch of height=0.5f on the heightmap
If there's a way to do this with trees, that would be great as well

[peak pivot]

My base problem is that I need to decrease the memory usage to avoid crashes at runtime on certain platforms.
Through profiling I've located that 90+ MB can be removed by enabling high stripping (this is a lot more than most other areas).
The problem is that the game is using this dependency injection system that creates various objects and feeds them their arguments into their constructors.
These are stripped away and there are a few 100 instances of this.

I've written code that identifies the types and I can go through and fix all these. But unless I can get some sort of system in place that detects cases. Any new class added to the game would cause a runtime error on that platform.

[leaden ice]

can it be done in unit testing?

[peak pivot]

So my goal is to run some reflection code in a unit test which can find all of these cases. and print out the file/line of that class rather than System.Type.FullName

Well a playmode unit test

[pine jungle]

?

[polar marten]

can you be more specific? do you mean il2cpp on ios?

[peak pivot]

NDA platform.

But yes, it is il2cpp

[hexed oak]

Is there some optimization that can be done?

Are there memory leaks? How large are your memory leaks?

[peak pivot]

There are other optimizations that can be done.

[polar marten]

NDA: "not doing anything"

[peak pivot]

But decreasing the executable+dll size is the low hanging fruit I've located

[hexed oak]

Seems like a lot of work for low hanging fruit

[polar marten]

well good luck on your journey here

[peak pivot]

Thank you.

[hexed oak]

I'd go through every class and check Update loops first

[potent sleet]

What don’t you get

[polar marten]

i'm not sure what platform would be sensitive for a 5 year old game

[pine jungle]

using System.Collections;

public GameObject interaction_Info_UI;

    Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
    RaycastHit hit;
    if (Physics.Raycast(ray, out hit))
    {
        var selectionTransform = hit.transform;

        if (selectionTransform.GetComponent<InteractableObject>())
        {
            interaction_text.text = selectionTransform.GetComponent<InteractableObject>().GetItemName();
            interaction_Info_UI.SetActive(true);
        }
        else

[peak pivot]

The game has been in development for 5 years.

[polar marten]

yeah...

[potent sleet]

And the namespace is still missing

[pine jungle]

what name space wich line

[polar marten]

well what would be most helpful?

it sounds like you started working on a game recently that is poorly engineered, and you're being asked to do something that doesn't make sense, it's not clear if it was your idea or not so don't take that personally

you can't tell me what platform it's on, which isn't sensitive, but you think it is

i am no expert, but it stands to reason if you're writing linters to work around DI, which was a fateful and bad choice, this game is going to take 10 years to develop

[peak pivot]

The overall game isn't poorly engineered but there were some early decisions like relying on dependency inject that are definitely things I wouldn't have done even 5 years ago.

[polar marten]

The overall game isn't poorly engineered
you know the 5 stages of grief don't happen in order or one at at ime. you can experience denial and anger at the same time

[peak pivot]

The game is already out, but not on the platform I'm currently developing against.

[polar marten]

okay i mean you can see in this chat, people talk about the switch, quest pro, various HMDs all the time here, it of course doesn't violate any NDAs

i'm not going to know what the game is, and it's not even going to be sensitive that a game is being released for a platform...

anyway, i'm not trying to raz you up on this

90MB is both a lot and not a lot of memory

[peak pivot]

@polar marten I'm not taking any offence to what you're saying. I think it's quite reasonable.

[polar marten]

okay okay

just checking

you can rip out DI in a week. that would be the best solution. the thing probably has 1 implementation of everything anyway

otherwise, i think you should generate link.xml

and avoid requiring [Preserve]

you can also simply preserve your player assembly

[peak pivot]

And yeah 90MB isn't a lot but when we only go above our memory cap with about 200MB having a simple setting that we can change to get 90MB back is very tempting.

[polar marten]

yeah that makes sense to me

[pine jungle]

it pre made scrip so i dont now anything about it

[polar marten]

i think you should try a simple solution first, like preserving all types and members in the player assembly using link.xml or the attribute (i forget which one is for assemblies)

and see what happens

[potent sleet]

Well you're in #archived-code-general , you should know what a directive /namespace is

[polar marten]

you are probably going to get 90MB back from generics in a serialization library, not from your player assembly

[peak pivot]

The main thing I want to avoid is that other team members that aren't directly working on the port will commit things by mistake that causes crashes, I rather have a nice "Hey, this class is missing [Preserve] on its constructor, please add it."

[polar marten]

yeah only link.xml will really protect yo ufrom that in the long term

or freezing usage of DI

[pine jungle]

not in C+

[peak pivot]

I'll look into it more as I understood it you had to be very specific for the method.

[polar marten]

link.xml is very flexible

[potent sleet]

c+?

[pine jungle]

it is the language this scrip is made in

[potent sleet]

it's not tho

a quick googling will reveal to you

[pine jungle]

what is the language then beguse its say c+ as the language on the website i found it

[potent sleet]

where, show me it says c+

[deft pebble]

C+ is not even a language tho

[potent sleet]

it is

it exists it neverland

[deft pebble]

It says C#

[potent sleet]

where do you see C+

[orchid bane]

For some reason my tiles have their colliders 1 pixel bigger than their sprites are, why can that be?

[pine jungle]

oops

[deft pebble]

Just a guess, but do you use atlases for your sprites?

[pine jungle]

yea it say c# i am dume but still dont now how to fix beguse try everting and it still not working

[orchid bane]

It's a multiple type sprite

[potent sleet]

again. Ur missing the namespace for Text

do you know how to look it up in the docs?

a c# basics would help you understand what it is

[pine jungle]

no i just sarted game deving

[potent sleet]

alright post in #💻┃code-beginner

Anyway, You should probably learn about TextMeshPro.
It behaves exactly the same as Text component but it's now the standard text and Text is Legacy

[pine jungle]

i still dont see the problem

[orchid bane]

@deft pebble could you help me with it?

[ancient sable]

how to reduce amount of gameobjects in a 2d game? I'm trying to make a game similar to terraria just for fun and I havnt ran into the issue yet but I do know that once im trying to make an actual world (and not just this small testing area for debugging while making it) having every block be its own gameobject will be way too laggy. Is there any way to try to reduce the amount of gameobjects im using for the world while still being able to interact with each tile (just the size of a 1 by 1 square) separately. Also are 2d gameobjects more efficient than 3d ones?

[deft pebble]

You could use DOTS(TM)

[potent sleet]

chunk loading probable?

[deft pebble]

Also, not sure in 2d, but minecraft just generates all blocks as a single mesh, you probably could use this approach in 2d too

[ancient sable]

would I still treat them all as seperate gameobjects, just disable them if a certain range away from player? Or is it different than that

[ancient sable]

possibly. If they are all a single mesh how can I interact with each "tile" seperatly or smthn? Do I misunderstand something about mesh?

[deft pebble]

You would have to have some sort of array that contains data with all the tiles, and when you want to check which tile is where, change this array

But having a huge array of structs still would be much more efficient then having tons of gameobjects

[ancient sable]

yep

[deft pebble]

I remember I saw a vid where someone explained how terraria managed to have this insane count of tiles, let me check

It's not Unity related, just a general concept

[ancient sable]

Ok. If you could send me that if you find it please send it, and thanks

[hexed pecan]

Single mesh? Pretty sure they are chunks

[thick socket]

but is each chunk a single mesh?

[deft pebble]

Yeah, and chunks are connected into single mesh iirc

[thick socket]

(idk anything about chucnks or meshes)

[potent sleet]

Chunks aren't invidual no

[ancient sable]

ok

[thick socket]

if you find it ping me with it plz 🙂

seems like learning that stuff might be smart down the line

[potent sleet]

Catlike coding or Red has good articles

I think sebastian league did one as well but cant recall exactly

[deft pebble]

I think it's this one @thick socket
https://www.youtube.com/watch?v=YIDbhVPHZbs

[thick socket]

lol

[hexed pecan]

Nice video title

[thick socket]

the title says "Redacted: Mostly inaccurate" 😭

[deft pebble]

yeah... back when I watched it, it wasn't redacted 😄

[thick socket]

xD

[deft pebble]

4:48 - Chunks? Yeah, Terraria has none of that. At all. It never did. It just uses a giant Tile[,] array, which is idiotic, but works for vanilla version of it.```

In the comment section

The huge "redacted" comment is actually pretty useful

[woeful leaf]

How come this script also grabs the parent's rect? Shouldn't it only get the children's rects?

using UnityEngine;

public class SpaceOutTest : MonoBehaviour
{
    [SerializeField] private Vector3 space;
    private RectTransform[] rect;

    [ContextMenu(nameof(SpaceText))]
    private void SpaceText()
    {
        rect = GetComponentsInChildren<RectTransform>();

        for (int i = 0; i < rect.Length; i++)
        {
            rect[i].localPosition += space * i;
            print(rect[i]);
        }
    }
}

[main shuttle]

https://docs.unity3d.com/ScriptReference/Component.GetComponentsInChildren.html

The GameObject that you call GetComponentsInChildren on is always searched regardless.

[woeful leaf]

But why?

That doesn't make sense does it?

[main shuttle]

I only knew those functions were like that. I have no idea why they do it this way of course, seems rather unintuitive.

[woeful leaf]

seems rather unintuitive
Yeah I'd say the same, it's confusing as balls

So how can I make it that it doesn't take the parent then?

[main shuttle]

Regardless it takes it. So you need to skip it in the foreach

[woeful leaf]

Should I just make it a list and remove the first element?

[main shuttle]

Seems risky, you could just do if gameobject != rect.gameobject

[woeful leaf]

Why's that risky

[main shuttle]

It says nothing about sorting, if you want to take that risk that's fine by me. I have no idea if IL2CPP for example would give a different result then mono then or whatever.

[light wraith]

the first object isn't for sure the parent + you could accidently have the component removed or use this script on a different object and miss it.
generally it's just bad practice

[woeful leaf]

I mean the only thing it does is you slap it onto a parent and it spaces out the children by a set amount

[light wraith]

so it's just a save 1 line to check for the game object

[woeful leaf]

So it's not a real big risk

[main shuttle]

if gameobject != rect.gameobject = no risk 🙂

[woeful leaf]

I suppose but I don't see how it'd fail

[main shuttle]

But you do you

[light wraith]

it can be an annoying bug that you will find in a later debug

[light wraith]

Imagine you use this script on a different object that doesn't have the component you are looking for.

you find it in the children and remove it from the first child.

than your script missed it's point

[woeful leaf]

It's still dependant on the index though, currently it causes the first child to be moved by 60 instead of 0 due to it doing space * 1 instead of * 0 since it increases the i due to the parent

What if I just do that if, and remove it from the list if it succeeds?

[main shuttle]

Yeah, you could do that. You could also have an extra index outside that counts the valid rects, and don't ++ that one if it is the current gameobject.

Many ways to go about this.

[woeful leaf]

I suppose

Thanks for the help :)

[main shuttle]

Np

[woeful leaf]

This works now :D

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

public class SpaceOutTest : MonoBehaviour
{
    [SerializeField] private Vector3 space;
    private List<RectTransform> rect;

    [ContextMenu(nameof(SpaceText))]
    private void SpaceText()
    {
        rect = new(GetComponentsInChildren<RectTransform>().ToList());

        if (rect[0] == (RectTransform)transform)
            rect.Remove(rect[0]);

        for (int i = 0; i < rect.Count; i++)
        {
            rect[i].localPosition += space * i;
            print(rect[i]);
        }
    }
}

[pearl swallow]

So, I'm trying to have bullet swapping based on my character's typing. The bullet prefabs are different instances. Below is how I organized it in update:

 if(boost>=100 && slimeType == 1)
        {
            projectile = GameObject.Find("FlameBullet");
        }

        else if(boost>=100 && slimeType == 2)
        {
            projectile = GameObject.Find("IceBullet");
        }

        else if(boost>=100 && slimeType == 3)
        {
            projectile = GameObject.Find("RockBullet");
        }

        else
        {
            projectile = GameObject.Find("SlimeBullet");
        }

Interesting, didn't know you could do (RectTransform)transform, would have expected a getcomponent of some sort.

on another topic, i am trying to have my gameObject stand on a tree (this is a squirrel controller if ur wondering). so i am casting a ray from my position to the tree and setting my rotation to the normal of the hit. does anyone see a problem with this approach or even have a better one?

                Ray ray = new Ray(transform.position, toTree);
                if (Physics.Raycast(ray, out RaycastHit hit, 5, LayerMask.GetMask("TallVegetation")))
                {
                    if (hit.collider.gameObject == targetTree)
                    {
                        transform.rotation = Quaternion.Euler(hit.normal);
                        //body.AddForce(-hit.normal);
                    }
                }```

[pearl swallow]

There/

[main shuttle]

What slot in question? I don't really understand what you want to do with your code. Do you want to do some kind of prefab stuff?

[pearl swallow]

Yes

[main shuttle]

So why not just use prefabs?

[pearl swallow]

I want to swap the prefabs into that "slot".

I want to, but I have multiple prefabs that I'm trying to swap in, but I don't remember how to.

[main shuttle]

So you have 1 slot Projectile, and you want to put different bullets in it?

[pearl swallow]

Yeah. Projectile is the "holder" so to speak to house what type of object is shot.

[main shuttle]

I would just have an array of all the projectileTypes, and get a projectileType and set it in projectile.

So an array of prefab Bullets, you could also just serialize them independently if you would want. Doesn't really matter much with 4 types.

[pearl swallow]

Alright, thank you, that should help me narrow the search.

[devout lodge]

hi, I have a prefab with child objects, but if I instantiate this prefab, it only creates the parent gameobject. how can I fix this?

[leaden ice]

that's not how Instantiate works, so I'd assume your prefab doesn't actually have children

or the children are being destroyed by your code right after being instantiated

[devout lodge]

oh then how can i duplicate a gameobject with children?

i also tried by setting it as a gameobject instead of a prefab, but same result

[swift falcon]

Asking again how can I make a Navmeshagent not decelerate instantly when reaching its destination

[leaden ice]

Instantiate duplicates it with all children

There's no way to duplicate it WITHOUT its children

show your setup and your code

and prove me wrong

[devout lodge]

then i am confused because the gameobject definitely has children

[leaden ice]

but I think you've just set something up wrong

[leaden ice]

show us

show everything

[devout lodge]

ok wait

[leaden ice]

why is your "prefab" in the scene?

this is not a prefab

[devout lodge]

yes i said i tried with prefab, then with gameobject

[leaden ice]

Click here

where does this take you

(make sure project window is open when you click it)

[leaden ice]

does it take you to somewhere in the project window? Or to the object in the hierarchy

[leaden ice]

ok now show the inspector for this object?

the AI Snake object

[leaden ice]

Can you show the AI script

[devout lodge]

yes

can you show that

probably that script is destroying it

[devout lodge]

https://paste.ofcode.org/CPXgYJYCkYBLnUJP7mXn7V

perhaps it is the 'RemoveSnakePart' method

debugging now

[leaden ice]

I think it's almost definitely something in this script

DestroySnake is running perhaps

[devout lodge]

yeah

[devout lodge]

weird if it is but gonna check now

oh youre right

weird thanks

[leaden ice]

seems like you have two bugs then:

• DestroySnake is running when it shouldn't
• DestroySnake is not destroying the entire snake, it's leaving that top level object behind

[devout lodge]

yeah so i have collision detection between snake parts and i guess when im instantiating the ai snake, its own snake head is colliding with its own snake parts

so just gonna make sure that doesnt happen

thx for the help :)

[leaden ice]

that will happen if they have their own separate Rigidbodies

Hello guys. I have a small problem with my code. Im trying to do a little physics game. The code works and all, but i dont really want to move the center of mass. I though about creating a hinge joint, but that sadly doesnt work. Now can someone help me with my problem?

Code:
https://paste.ofcode.org/hb66DszBskKkNvJG35aw5d

[trail mist]

sorry for posting here but can anyone tell me why is my game build on black screen ?

i made another scene (this one) just to test and still same problem

[leaden ice]

why are you changing the center of mass in your code

[potent sleet]

probably exported wrong index in Build Settings

also not a code question

next time use #💻┃unity-talk

[bitter trout]

Well i want it to be reallistically rotating, like if you grab something i want it to rotate around the grab point.

[leaden ice]

when you grab something in real life, you don't change its center of mass

[bitter trout]

Yeah i know, i did not find a different solution

[leaden ice]

all you need is a hinge joint correctly anchored at the position you grabbed it from

generally you'd also create an invisible kinematic Rigidbody at the mouse position, and use MovePosition in FixedUpdate to make that invisible object follow the mouse

that will give you realism

attach the hinge joint to the invisible object

you'd also need to use theBox.transform.InverseTransformPosition to get the correct local space position for anchoring the joint

[trail mist]

correct scenes index, it's littealy one scene and the one i did open

[bitter trout]

Ok, im gonna try this out.

[potent sleet]

show build settings real quick

[trail mist]

Theses ?

[potent sleet]

what does Game View look like in Editor

[trail mist]

i removed all the scenes and made a new empty one to see if the problem is only in specific scenes or in all of them

[trail mist]

like this

[potent sleet]

this is scene view

what about Game View

not the Build

[trail mist]

here is it

[potent sleet]

do you have any compile errors when exporting? have you tried another scene too

does only happen in build or in Playmode too

[trail mist]

only in build

i got these warnings for the first time, for shaders that are NOT used in this scene

i'll try removing them and building

[potent sleet]

maybe, they are just warnings and for shaders you may not use but yeah try

[trail mist]

https://cdn.discordapp.com/attachments/1020637603625701396/1070683656642895942/image.png

i really got shoked this morning when i tried to build for the fist time

UI elements renders but anything else dont

[potent sleet]

what kinda PC u got ?

are you on a laptop or something

[bronze rampart]

is the game still running in the background?

[trail mist]

yes im on a laptop

not the first time i did build a unity game on it

but first time igot the black screen

removing those shaders didnt help still black screen

[potent sleet]

hm maybe it doesnt support those shaders on ur laptops limited GPU

[trail mist]

not the first time i use them...

this scene also has no shaders since its a default skybox + cube

i'll update my graphics

[potent sleet]

have you tried, new blank scene, different camera , no post processing

start eliminating one possibility after another, debug

[bronze rampart]

@trail mist assuming a blank scene with just a camera in it renders as expected can you try and narrow it down a little more. for example go to ur scene and disable everything then re enable things one at a time until the problem re appears. its a bit brute force as far as trouble shooting go's but you didn't give much info

[trail mist]

thats the scene i've been showing you al time

i got this warning after building the empty scene

[bronze rampart]

does it render as expected though?

[trail mist]

no. black screen

[potent sleet]

wait it's not finding Player assembly

[dusky coral]

hey im having trouble with lerp basic lerp stuff i would assume

[potent sleet]

whats error say

[leaden ice]

Vector3 doesn't have a .position

[potent sleet]

ah yes

[leaden ice]

which is exactly what the error will say

[bronze rampart]

ok ya try and address the warning. Im not sure specifically how to fix that off the top off my head but that would be my next step if it was me

[potent sleet]

no Idea what I read those as Transforms xD

[potent sleet]

Um a missing Player maybe a problem

if they are talking about the Player that runs on your PC to run the game

[dusky coral]

thank you now the t is the only thing needs fixing says the name t doesn't exist

[leaden ice]

you can't use variables that you never defined

[potent sleet]

https://gamedevbeginner.com/the-right-way-to-lerp-in-unity-with-examples/

[leaden ice]

you never created t, so t does not exist

[dusky coral]

thank you

[potent sleet]

what threw me off is you kinda wrote it correct the firs time xD @dusky coral

except for t

[dusky coral]

would {SerializeField} private flot t;

[dusky coral]

lol

[potent sleet]

it's [SerializeField]

you still need the t to move

like t += Time.deltaTime

but this isnt correct way

the link I sent you show example how

[dusky coral]

ok thank you

[trail mist]

building after disabling burst compilation : results

[potent sleet]

it's not the burst compile

[trail mist]

Im litteraly ttrying anything i read online

ill reboot real quick brb

[potent sleet]

Did you try another project ? is it only this

[tepid river]

im trying to import my monobehaviour into my unit test, but i cant figure out how.

using System.Collections;
using NUnit.Framework;
using UnityEngine.TestTools;


public class NewTestScript
{
    // A Test behaves as an ordinary method
    [Test]
    public void NewTestScriptSimplePasses()
    {
        // Use the Assert class to test conditions
    }
}

separate file:

using System;
using UnityEngine;
public class ShipPlayerInput : MonoBehaviour
{ ... }

it doesnt know ShipPlayerInput by default in the test script and i cant figure out what to import

[trail mist]

was thiking of trying on another project and will do rn

i have this projects that have similar shaders so ill try

it will take some time so brb

[leaden ice]

you probably didn't set up the assembly reference from the test assembly to your game assembly

And/or didn't create the test assembly and/or game assembly in the first place

[tepid river]

the first one

thanks, can finally import.
am new to this whole dotnet show

Question regarding ScriptableObjects:

Pictured is a ScriptableObject I have created as it appears in the Unity inspector. It is created from a class called Item that inherits ScriptableObject. I have created this Item from the Create Asset Menu, and put in a few details relevant to this item.

The Item class has an enum called "ItemType", and by selecting "Seed" from the drop down menu in the inspector, this particular Item's itemType is set to "ItemType.Seed".

I want to display different values to be modified in the inspector based on the "itemType" that is selected by the user. For example, "ItemType.Weapon" might have variables that I want to change in the inspector called "attack" or "speed", however, "ItemType.Seed" would have no use for something like this, so I might want variables such as "growthRate", or a bool like "canPlant" to be visible in the Inspector instead.

I might be going about this the wrong way... it might be better to create an entirely new script with a class called "Seed" which inherits "Item". So rather than having one "Item : Scriptable Object", I would have other scripts like "Seed : Item", and "Weapon : Item" which are still items, but have their own functionality.

What do you think?

[trail mist]

life update : tried another project, and it's fine even with those shaders that i deleted, animations plays sounds are ok everything is ok

[trail mist]

ill return to the main project now

and try again

[west cobalt]

this might be dump but i literally dont kniw how to get startet with unity
all the tutorials start with some done code (ofc not everything) but while reading/watching that i still have no idea how to start from scratch and all the stuff
are there any tutorials that arent like 5 years old but explain this whole thing

[trail mist]

ask for help in #💻┃code-beginner first
Do you have basics in coding btw ? like litteraly understanding the int / floats / bools / if() ?

understanting them first will make you better since you will understand what the videos do sometime

[somber nacelle]

!learn

[tawny elk]

🧑‍🏫 Unity Learn can offer you over 750 hours of free live and on-demand learning content for all levels of experience! Make sure to check it out at https://learn.unity.com/

[west cobalt]

yes i have the basics from java (and im trying to get into c# which isnt very different)

[somber nacelle]

there's also some beginner c# courses pinned in #💻┃code-beginner

[polar marten]

create a prefab. change your scriptable object type to a monobehavior. fill in the fields. then, if you need more stuff, like weapon behavior, add another monobehavior.

don't use scriptable objects to compose behavior. use prefabs

where did you get the idea to use scriptableobjects?

[distant glen]

I have a bunch of items in my game. These items have different values, such as what they are worth, their descriptions to display in the inventory, the sprite to display in UI etc.

If I wanted to instantiate one of these items in the scene, then I would create a GameObject, and that would copy over the values of the ScriptableObject relevant to it.

I got the idea watching Brackey's tutorial for an Inventory system.

[polar marten]

well

instead

make a prefab

and instantiate the prefab

which is even simpler

and easier

and better

in every conceivable way

that you could possibly fathom to dream or imagine in your mind

and never make scriptable objects again

ever, in all of history, for the rest of your life and afterlife

then you owulnd't have to copy relevant values. it would Just Work

there's no copying

and you can compose scripts

to do all sorts of things

[distant glen]

Confusion. Why are ScriptableObjects implemented in the first place then? They seem like a good alternative to JSON or XML

[polar marten]

https://github.com/cathei/AntiScriptableObjectArchitecture

see "Reason #1"

[sinful juniper]

Hello, I don't know if my problem comes from code or Unity, I'm quite new in Unity and i'm having objects where I can't set the value :

public GhostBehavior initialBehavior { get; private set; }```
I have this script member in Unity

[polar marten]

#💻┃code-beginner start with a tutorial. properties do not appear automatically in the inspector. use a field

[hexed pecan]

I believe you could also use [field: SerializeField] attribute to expose the property

[leaden ice]

As a beginner they should start with learning the basics.

Just use a regular field

[sinful juniper]

(sorry for the wrong channel) thanks for the answers, I'll do the tutorials I just have a project I have to submit soon and I didn't have the time to make all the tutorials I'd liked ^^"

[leaden ice]

#archived-lighting not a code question

[leaden raven]

whoops didn't know that channel existed

[fallen lotus]

is something like this possible with function parameters? I know this specifically isn't possible but i'm trying to do this.

        public void LoadScene(string sceneName || int sceneIndex)
        {
            PlayerPrefs.SetString("sceneToLoad", sceneName || sceneIndex);
            SceneManager.LoadScene("Loading");
        }

[simple egret]

No, you can't make variable types. You can make an overload though, ie. two methods named the same but with different parameter types

[fallen lotus]

oooo i did not know you could do this

thank you!

also is it possible to retrieve the version number via code from the player settings?

[simple egret]

A quick Google says it's Application.version

[grim pebble]

In order to teleport a character controller, you must first disable the CC, then change position, then re-enable. Otherwise the teleport fails. However, disabling character controller doesn't fire OnTriggerExit on triggers the CC is currently inside of

So teleporting a CC out of a Trigger doesn't trigger the exit call

how to deal with this

[simple egret]

See if teleporting without disabling notifies the trigger exit. Just call Physics.SyncTransforms() right after you change the position to avoid the CC from rolling back

[grim pebble]

Oh, nice, wasn't familiar with that call. I am sure that will work, lemme see

Yeah that works, nice! I was never thrilled about the disable/enable thing, didn't know there was a more appropriate way to do it. Thanks

[vale wharf]

How can I get the position of a UI element inside a scrollrect relative to the content object?

take the red rectangle for example. At it's default position it should have a relative position of 0, which should go negative as I scroll up

[deep fable]

Is there a way to check if a GameObject has at least 2 instances of the same script monobehaviour attached? (Basically when a script needs to remove an effect on the GameObject it is attached on but only if there aren't other instances of the same script)

I could use GetComponents and check the length, but is there a better way?

[grim pebble]

My instinct is that using whole components to represent individual effects might not be entirely how they are meant to be used, at least that's my understanding

I don't think you are supposed to be adding/removing components on the fly all that much

I've modded a handful of mainstream unity games and poured over their code and I have never seen a component be added or removed at runtime

[vale wharf]

anyone?

[grim pebble]

Perhaps try #📱┃mobile or #📲┃ui-ux

[vale wharf]

why even have a code channel then

[grim pebble]

I didn't say you can't ask the question here Just seems like nobody here at the moment knows the answer, but those other channels might have someone who does

[thick socket]

so if I have like 100+ items you can drop

I should be making 100+ prefabs depending on the item?

[deep fable]

Yeah thanks.. Effectively I have other ways to do this (maybe have a single EffectsHolder script that has an array/list of the individual effects applied to the gameobject)

[thick socket]

why?

[grim pebble]

I read this and I'm trying to wrap my head around a way to use an SO that isn't an immutable data asset

[thick socket]

some may store a players inventory in it for ex

or use it to increment timer

[grim pebble]

Yes exactly. That's what I do, just have a component that handles all the buffs, handles adding/removing them (and also expiring them over time), and makes them available to the stats component (to observe their effects)

[grim pebble]

?? are you saying that you can modify SO variables??

Like at runtime, for all users of that SO ??

[thick socket]

I've got a list of like Items and everything...pretty sure this would be rough to do in just code

[thick socket]

I've seen a tutorial do it 😭

[grim pebble]

This isn't at runtime though this is at editor time

[thick socket]

I just use SO as like a template for data I will use later

[grim pebble]

At the very least why not split them into separate SO files

Having it all in one file seems particularly annoying to work with

[thick socket]

I mean

[grim pebble]

In a list like that, can't like duplicate easily and stuff

[thick socket]

its 1 SO that just holds all my items

[grim pebble]

It's just like a library of those items, right? You're not changing those items at runtime?

At runtime means, during the game

[thick socket]

right

(at least not atm)

[grim pebble]

I think that is how you are supposed to use SO's

[thick socket]

correct

[grim pebble]

But putting it in one as a list like that seems a bit clunkier than having a folder of separate files for each item

[thick socket]

that would be a folder with hundreds of files

[grim pebble]

Yea

[thick socket]

seems easier to just store it in a list

[grim pebble]

As opposed to a list with hundreds of entries, what's the difference?

Idk I'd rather work with file explorer than unity inspector

[thick socket]

fair

[grim pebble]

You can sort and stuff

[thick socket]

but its a lot more you need to load at runtime for one

you can write code to sort your lists and fill things in inside SO

like a one-off

[grim pebble]

[thick socket]

I filled in like the Sprite name/helmet name

[grim pebble]

I'm guessing you're not using version control

[thick socket]

then in code set id to go through and set the super long ID to data about it from elsewhere

[thick socket]

yessir

git 👌

[grim pebble]

But you are 'sorting' the file which means changing it

[thick socket]

right, just did that like once or twice

then got rid of the script code and the SO saved all the data that was set

which is why some people use it to store data

cause it can be set in code and stays when you stop playing

[grim pebble]

I'm not disputing using SOs, I'm not sure what the hate is for when they are used correctly

I'm concerned about the single-file format you're using

[thick socket]

that was my question lol

[grim pebble]

It hackles every instinct I have

[thick socket]

that github said it hates it xD

[thick socket]

funny, making it like this is my instinct

make a list that stores all my data

and go grab it when I need it

[grim pebble]

That github is garbage take

Conclusion

❌ DO NOT USE ScriptableObject Architecture ❌

Only use ScriptableObject when you need immutable data asset. If possible, don't use it at all. Editing design data with Unity Inspector is horrible. Use better alternative for this too, such as using Spread Sheet.

This take is awful

Use a spreadsheet ???

Either you are using SO or GameObject

[thick socket]

yeah, hes got some awesome spreadsheet, haven't bothered figuring it out yet tho

[grim pebble]

Either way you are editing design data with inspector

[thick socket]

if there was a youtube video showing like HOW to use his spreadsheet I would probably instantly start using lol

[grim pebble]

I certainly would not

Separate files are good, editing with inspector is fine, git ingests GameObject and SO files just fine

[tender fog]

uh how do I rotate something

[thick socket]

https://github.com/cathei/BakingSheet

[grim pebble]

[tender fog]

i was ignored in the beginner chat

[grim pebble]

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

There's also something like FaceTowards

[tender fog]

ok ty

idk why that didnt appear on google lol

[thick socket]

FaceTowards doesn't really work great for 2D games iirc

[thick socket]

ex)

protected void Flip()
    {
        character.transform.localScale = new Vector3(-1f * character.transform.localScale.x, character.transform.localScale.y, character.transform.localScale.z);
        facingRight = !facingRight;
    }

[tender fog]

im not sure what that means but I shall take that into account

[thick socket]

😄

[tender fog]

thanks for the help

for 2d should I use Z?

[grim pebble]

I don't think ya have z in 2d

I never touched 2d

[fluid lily]

If I have one array of objects and I know they can be cast another type, can I just do (Components[]) for example to cast each element of the array?

[tender fog]

i tried all of them in the editor and Z was the only one that moved them

[grim pebble]

Nah it doesn't work that way. If you are using an array you can do ConvertAll

var newArray = Array.ConvertAll(array, item => (NewType)item);

Casting the array like you suggested will fail because an array's contents type doesn't effect the array's own ... castability? lol

[bitter trout]

I think, uh i did something wrong. Sorry, im not very good with anchors and have never done anything with them. :

https://paste.ofcode.org/ecgbqy3ri2pWbRF6vEHCbk

[grim pebble]

One day I'll just type Destroy(gameObject) instead of Destroy(this) on the first try

[uncut vine]

Hi all. I want to iterate on gameobjects and animate (animator.SetTrigger) them in order. This doesn't seem to work, the order is not kept. Any direction on how to do this?

[leaden solstice]

C# has magical covariance rule for array

string[] myStrArray = new string[10];
object[] myObjArray = myStrArray;

This is legal.

[leaden ice]

uhhh it is?

what happens if you then do myObjArray[3] = 5;?

[leaden solstice]

You get runtime exception 😄

[leaden ice]

I see

[leaden ice]

you cast each element by casting each element, not the array

this is the inverse of what @leaden solstice was illustrating right?

E.g.

object[] myObjArr = new[10];
string[] myStrArr = (string[])myObjArr;```

this is not a valid cast

[leaden solstice]

Yeah that's illegal

I'd go with IEnumerable<string> myStrEnumerable = myObjArr.Cast<string>()

[thick socket]

is there a video about how to use your bakingsheet somewhere?

seems really useful but not super easy for me to figure out 😄

[somber nacelle]

you would think it's illegal, but it's actually not apparently
https://dotnetfiddle.net/kLXDfO

[leaden solstice]

That array is originally new string[], it's illegal when the array is originally new object[] like Praetor's example

[somber nacelle]

ah right, misread it lol

[leaden solstice]

I'd love to make a video tutorial when I have time 😇

I'm happy to help you adapting it tho

[vale wharf]

because that's what I want to do.

[thick socket]

❤️

Ill probably reach out to you sometime if I run into issues 🙂

[drowsy maple]

I need to copy components at runtime, which requires going through all the fields of a component and filling in the values from the original. But you can only do that once you have created the new component with AddComponent<>(), but by then it's already too late because that will call Awake() immediately on the new object which will inevitably access fields that you had no chance to initialize because they didn't exist up until that exact moment. Is there no way to add a component at runtime without also invoking Awake()?

[bitter trout]

Ok i fixed it kinda, but the target joint doesnt work anymore then? And it just behaves weird:

https://paste.ofcode.org/J3ANjRXFtH8aH8LLjr6Rrn

[leaden ice]

Why aren't you using a Hinge Joint

[bitter trout]

Im

What do you mean?

Ah know i know what you want me to do

I dont know if it will give me the correct results but i will try

[misty jewel]

@plucky inlet just a tiny update after all that, I realized the package already has an array that contains the selected objects I only noticed the next day and I feel dumb

[leaden ice]

you said you're using target joint

hinge joint seems more appropriate

[bitter trout]

Yes yes, i have figured it out now. I was just stuck on my previous idea.

[plucky glade]

Hi everyone! I just ran into a problem trying to use visual studio 2019 (I've tried both the "community" version and the manual installation version). Basically, I can open up the code editor while developing a project. Everything's normal, the thing is, every time I hover any text/code in the code editor, it will just crash, no message or anything, it just hangs and closes. Any ideas what could I do to fix this problem?

-Some important information
-I've not opened my unity project in 3 months, however, it doesn't just happen with this one project, it happens with older ones as well.
-by hovering any text/code, I mean putting my cursor over any of the code you would normally write in the editor, instead of showing some tooltip, it just hangs and closes.
-I've not updated either the unity version I'm using for all my projects nor my visual studio 2019, however upon encountering this error I've tried updating visual studio, same error.

I'm going to try uninstalling visual studio 2019 and let unity reinstall it for me and see if that fixes it.

Otherwise any possible solution you could suggest is appreciated

[bitter trout]

Tho i still have some issues, the object glitches through the ground when i go into the ground with my mouse. And i also want it to drag behind a little bit, like the target joint.

btw, should i put the hinge joint onto the grabbed object or the mousefollower

[leaden ice]

also try VS 2022

[leaden ice]

the grabbed object

[polar marten]

if you want to copy a component easily at runtime, assign the component as the only one on a game object, then Instantiate that game object

[bitter trout]

And with my other problems?

[drowsy maple]

@polar marten thanks for the tip but that won't do unfortunately, I need the component to end up on another, pre-existing gameobject because the component requires that exact rigidbody. Can't change how the rigidbody is accessed either since the component is from an asset and not my own.

[polar marten]

i think you can change how the rigidbody is accessed

[leaden ice]

because the component requires that exact rigidbody
This is not a bulletproof reason for it needing to be on that GameObejct

[polar marten]

you better start believing in making changes to assets

[drowsy maple]

i thought about that too, but that usually causes more trouble than its worth as you go down the rabbithole of refactoring the asset , especially if you want to keep updating to newer versions

[leaden ice]

much smaller rabbit hole than what you're trying to do

[drowsy maple]

i just settled for deactivating the destination gameobject right before the copy and then reactivating it

that also prevents awake from being called and doesn't seem to have any side effects from what i can tell

[plucky glade]

yup, that seems to have fixed it, thanks for the suggestion

[bitter trout]

btw the red dot is the mouse follower and the green one is the grab location

[shell scarab]

hello, could someone explain to me why ~0 == -1 is true? I would think ~0 is equal to -2,147,483,648, since all bits are flipped.

[bitter trout]

Can you answer my question?

Ah, im sorry didnt see youre on idle

[leaden ice]

Because ints use a "two's complement" representation

https://en.wikipedia.org/wiki/Two's_complement

[bitter trout]

Ah i found it. Its going through the ground, because im using Rigidbody.MovePosition which ignores colliders...

[odd zenith]

https://gyazo.com/e8c472ed6fefb0cb4208c96ead148853

ok so im learning perlin noise

and i accidentally made it do this

its cool but idk why it does that

ill shwo code in a sec

[leaden ice]

Looks like your standard perlin noise sampling to me...

[odd zenith]

yes but

why when i move the script holder up the thing doesnt move up it just makes waves? the tiles are transform.parented to the script holder object (empty gameobject)

[leaden ice]

because you're setting the world position of the tiles right here in your script

the parenting doesn't matter

[odd zenith]

o

how do i make it like

[leaden ice]

set local position instead of world position

[odd zenith]

adhere to the parent

how?

[leaden ice]

use .localPosition instead of .position?

[odd zenith]

o

i didnt know that was a thing thank u tho

now it's sliding around n stuf its being goofy

like moving up is fine the whole thing moves up

when i move it to one side or the other it slides a lot like stays intact but doesnt move with my mouse

im just tryina figure out why it works like that

https://gyazo.com/caca85010e9f33ed07d07723fa93bcb1

ok well i fixed it by using local pos when i get the x and y variables, but i stil don't entirely get why it works

[distant glen]

How can I stop a coroutine and restart it?

Image 1: Coroutine is assigned to a variable and called on Awake()

Image 2: Coroutine instructions

Image 3: The method I call to reset the coroutine.

It seems that once stopped and restarted, the old coroutine keeps running to some degree. It does not truly "reset".

[leaden ice]

I don't even see anything in the coroutine that's different. What does "resetting" it even mean for you

The old coroutine will not keep running, no

Are you asking about the soil resetting to the "fertile" state or something?

[distant glen]

When the coroutine starts, a function is supposed to be called between 10 and 20 seconds.

This functions as normal.

However, after resetting the coroutine, the function seems to be called between 2 - 3 seconds, or earlier than expected, as if the coroutine that was stopped previously continued to execute its code.

Resetting it, in this case, means resetting the timer before the DegradeSoil() function is called.

If the next time that the DegradeSoil() function was going to be called in 13.6 seconds, the ResetSoilDegradation() method should reset the timer to zero, and assign a new number between 10 - 20 seconds for when the DegradeSoil() function will be called.

[leaden ice]

Yes based on the code you shared this is how it should work

Maybe share the rest of the code?

Hi, I asked ChatGPT about using Events, but Im sure something is missing, here's a part of my code:
Basicly I just want my code to put a string into my console. It's just for Debug.Log yet
Also, I thought we had a way to put text into discord as code? I looked at the read me but it's not there. Was it removed or it's the wrong channel? XD
CreerEchiquier has no use for the clicking, it's not revelant to my question

[leaden ice]

this seems like a really weir dthing to do

why do this in code

instead of just configuring the event trigger in the editor

[quaint rock]

this code is like comically wrong and bad

[north moss]

Because the objet I want to add a listener arnt in the editor yet

[leaden ice]

make a prefab

[quaint rock]

you can literally just implement a pointer handler, or drag something into the event trigger instead

[north moss]

I can't make it as a prefab, it's created via GameObject.CreatePrimitive

[leaden ice]

anyway - PointerDown will only work if the object in question does not have:

• a Collider (if not UI)
• a Graphic (if UI)

and furthermore you need:

• EventSystem in the scene
• Input Module in the scene
• PhysicsRaycaster (2D?) if not UI
• GrqphicRaycaster if UI

[leaden ice]

you could use a prefab instead of using CreatePrimitive

you can also just write your own script that implements IPointerDownHandler and add that instead of this weird hoop-jumping with EventTrigger as well

[north moss]

I could... I didn't want to XD, but I guess I should lol...
So it needs a collider? argh... I think that's gonna be hard to click on it XD
I want to click on one of these Quad when I need to

[quaint rock]

i have never used EventTrigger once from code

its really just a thing meant for persistent listeners, better way to do it in code at runtime if needed

[north moss]

Okok

Thanks for all the info

[north moss]

Well, I understood why my OnMouseDown wasn't working tho! It has to be from a script attached to the gameObject. (I made a script making PrimitiveType without being linked to the GameObject). Basicly a non-Monobehavior was acting as a ghost-component of my object. I thought I could still use it that way but it seems I was wrong

[tough osprey]

Does C# treat "const int" differently from "int" because it knows it's value?
Here's two ints initialized, one as a const:

private const int kNumInstances = 3;
public int NumInstances = 3;

Trying to use the Public int instead of the const int I get a conversion error

[quaint rock]

well read the error, something is a long and you are using a uint

but no adding const just makes it constant

type is still int

[tough osprey]

... no, they're the same exact lines. The only difference is the final variable on those lines. kNumInstances is a const int, and NumInstances is just an int.

[quaint rock]

it might be because it knows its posititve if constant

but i doubt its that smart

[tough osprey]

If I change the Test 2 line to kNumInstances also, the error goes away, even though both kNumInstances and NumInstances are both ints.

My guess is that it actually is smart enough to know the kNumInstances is 3 and only ever 3. So the formula of "uint + 3 * int" will safely always be a uint? Whereas replacing "3" with some unknown int makes it riskier? Though by that logic, any uint + uint could exceed the capacity of a uint, so not sure

[quaint rock]

yeah would have to look into the resulting il more

if its doing that, it really kinda feels like doing a #define NumInstances 3 in C

[tough osprey]

although the other int in that formula is also a small constant so everything there is all already known at compile time (I want to make it dynamic :P)

[quaint rock]

well if dynamic just do the casting yourself as needed, or do not create a situation where you mix int types, and just do it all as long

[tough osprey]

yeah ... this is dealing with memory address stuff which I'm still wrapping my head around (BatchRendererGroup) so I didn't want to mess with types, but will give casting a shot

This entire sample code blows up a ton by trying to make it dynamic

Fixed it

[potent glade]

hi everyone, I am making a plugin for my webgl app:
I am using this function (java script)

GetArgs : function()
    {
        let source = document.getElementById('player').src;
        return source ;        
    },

but I am getting an error when returning the value... I want the src to be returned as a string... can someone help me know if I have to do something before returning the variable?

[trail sinew]

how would I add mass to this equation?

[west lotus]

-gravity* Time.deltaTime/mass

[unique trout]

So, I'm playing around with Jobs, specifically parallel jobs. I'm wondering if it's possible to add new jobs to a parallel job struct before it completes, or if I can only create a vector of them, removing the completed ones as they finish.

[west lotus]

Also pretty sure you dont need the second * deltaTime when calling Move you are already factoring it in the vel calc

[west lotus]

What do you mean add new jobs ? You cant schedule jobs from within a job afik

[unique trout]

Basically, on one frame I set up a ParallelJob struct and start it running. It probably won't finish on this frame, so I let it run, storing the ParallelJob in a static variable, then checking every frame if the jobs have completed and doing with the data what I need. However, it's entirely possible that before the ParallelJob completes, the player has done something which requires more of that same type of data being generated.
So, basically, can I add to the ParallelJob after it's started, or do I just create a new one, and make the static variable a vector of ParallelJobs?

Oh, and by Vector, I meant List. Bleh, too used to working in C++.

[west lotus]

Its not advisable to read and write to the same collection especially for a paralel job. There is a way to disable the restrictions but you will have to manage your offsets carefully. I suggest simply scheduling another job with the new data and aggregating on the main thread.

[unique trout]

Alright. Figured that'd be the case, but wanted to know.

[trail sinew]

i did -gravity * Time.deltaTime * mass and it does it pretty well

[west lotus]

You need to divide by mass

[trail sinew]

but multiplying seems to make it go faster

[trail sinew]

its definetly going slower when i set it to 2.5

[west lotus]

Well yes. A object with more mass is harder to accelerate

Thats how physics works

[trail sinew]

wont it go faster in earth

cause of air resistence

im not the best in physics

[plucky inlet]

you are mixing up acceleration and gravity here I think. If you want to move an object with the same "force/speed" as another and the mass is higher, its going to be accelerated slower then the lighter one. Your gravity is just another force that is affecting the acceleration. In gravity, all masses fall equally if their size is the same, otherwise you would be right with your air resistence.

[woeful leaf]

In theory the TryGetComponent should not run if button is not null, correct? (Due to it being && and not &)

 if (button == null && !TryGetComponent(out button))

Or does only doing it like this

if (button == null)
  if (!TryGetComponent(out button))

achieve that?

[plucky inlet]

It has to check both, because you ask it to be both.

[rain minnow]

it checks both conditions . . .

[plucky inlet]

the second one would be what you expected

[woeful leaf]

Doesn't it only do that if it's &

[rain minnow]

you're doing if button is null and if there is no component . . .

[plucky inlet]

Basically its asking the same thing twice

[woeful leaf]

It's in an OnEnable so it gets run whenever the object is enabled again

[rain minnow]

i see what you're asking. && will only check the right-hand side if the left-hand side is true . . .

[woeful leaf]

And I assume TryGetComponent is more performance heavy than just checcking if button is null, no?

I also don't want it to reassign it for no reason

[rain minnow]

& will check both conditions, regardless if the left-hand side is true . . .

[woeful leaf]

Yeah so my statement is correct then, right?

[woeful leaf]

This statement

[rain minnow]

yup . . .

[woeful leaf]

So in terms of execution this'd be the exact same then, right?

[rain minnow]

well, no. TryGetComponent will not run if button is null . . .

[woeful leaf]

You mean will run?

[plucky inlet]

Thinking about it, I think I used something like

if(object != null && object.Value == 1)

And that did not give me a null reference if the object was actually null, so its not checking the second statement in the if brackets when the first is already false here?

[rain minnow]

nope, it will only run (check) the second condition if the first condition is true. the first condition is if button == null . . .

[woeful leaf]

I mean yeah but it does the same for both, no?

[plucky inlet]

No, if your button == null, it will never try to check your component, but if its in the same statement, it will check if its null and if you do not have the component

Which makes me wonder again, why my if statement up there is working 😄

[woeful leaf]

TryGetComponent does not run if the button is not null

 if (button == null && !TryGetComponent(out button))

And here TryGetComponent also does not run if the button is not null (Again, due to the difference between & and &&)

if (button == null)
  if (!TryGetComponent(out button))

Or is this what I'm saying still wrong

[woeful leaf]

Because if this is right, than this is true as well right?

Or am I missing something big here

[plucky inlet]

TryGetComponent will run, because you want the if statement to check if BOTH are being met. You only run the code if both are correctly returned. I am not sure it is foreseeing the next argument in your if statement. Let me test this real quick 😄

[woeful leaf]

&& exits the statement if the first condition is already false, whilst & does not

&& can do that because if the first condition is false, it does not matter what the value of the second condition is

[plucky inlet]

Ohh, okay. was just going to read the docs because I never thought a lot about that 😄

Thanks for clarifying. But then, your statement all the way up is correct. 😄

[woeful leaf]

This might help
https://www.c-sharpcorner.com/code/71/difference-between-and-in

There was a stackoverflow post that explained it well, as well, but I can't find it anymore

[plucky inlet]

I am so used to handle if with always double char statements 😄

[woeful leaf]

By the latter you mean always doing the operator double? So && instead of & and || instead of |?

Or do you mean something else

[woeful leaf]

Also FYI, there isn't really a reason to use & or | over it's "double" form afaik

doubling it up is just more performant

[plucky inlet]

Yeah exactly. I always use && and | , guess its just the years of coding same patterns making me do that 😄

[plucky inlet]

Well then I am on the safe side I guess 😄

[woeful leaf]

And | or ||?

[rain minnow]

yes, TryGetComponent does not run if the button is found (not null) . . .

[woeful leaf]

Yeah so what I said is correct, right?

[rain minnow]

the wording makes it difficult to understand, so i changed it . . .

if the button is found, the 2nd condition will not run . . .

[woeful leaf]

Yeah exactly, which is what I want because I don't want it to re-assign or even run a TryGetComponent if the button already has a value

[woeful leaf]

Because you should be using || if you're using |

(Same logic applies)

[thin aurora]

They both have to run in this case. If button is null the statement will short-circuit since it's already false, and TryGetComponent will not run in that case. Same in reverse when you do an or check with || and button is null.

[woeful leaf]

If button is null the statement will short-circuit since it's already false
Wouldn't it be true in this case?

[thin aurora]

Dunno what you mean with & since logical and is not valid here as far as I know

[thin aurora]

It is, but a conditional AND must also be run if you want to check for true

If you want it to short circuit, change && to ||

[woeful leaf]

What is not valid about it?

[thin aurora]

Try it, maybe it is

I don't think a logical and is valid

I think in this case it will do a bitwise operation with the results of TryGetComponent and button == null, which makes the question if that is possible on two booleans?

Why don't you just use &&

[woeful leaf]

I do I thought you said doing & is not valid though (as in your IDE would throw an error)

I always use &&

[thin aurora]

I more mean like validity when it comes to creating an if statement if a button exists like this

This probably works, but it's probably not really useful

I think what you do now is if (0 & 0) which is false if I remember correctly

Or if(1 & 0) I think actually

[woeful leaf]

This appears to work fine

I think

[thin aurora]

Of course, what do you expect?

[woeful leaf]

I don't know you're questioning everything and confusing me

[thin aurora]

I got confused the moment you started wondering if just using & is valid

[woeful leaf]

Nonono lmao

Only reason I brought up & is to illustrate the difference of && short-circuiting and & not

I wasn't actually planning on using & or some shit lmao

[thin aurora]

Ohh

[woeful leaf]

I don't think I'll ever use &

[plucky inlet]

Same 😄 Not even gonna keep that in mind from now on! 😉

[rain minnow]

it's good for bit stuff . . .

[woeful leaf]

Haha

[woeful leaf]

I suppose, but that's a niche I'll probably never touch

I mostly use it with assignment (when I don't care about short circuit) such as this

isValid &= some_expression;
isValid &= some_expression;
...
if(isValid) { ... }```

[thin aurora]

BTW, this checks if you can't get a reference to the button if it's not cached?

[woeful leaf]

What do you mean?

[peak pivot]

Otherwise I count it & and | as bitwise operators.

[thin aurora]

Please configure your !ide before asking questions here.

[tawny elk]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)

• VS Code*
• JetBrains Rider
• Other/None

*VS Code's debugger plugin is unsupported.
We recommend using VS or Rider instead.

[thin aurora]

This is the point of the if-statement, right?

[rain minnow]

they're asking what your statement is checking. the point of it existing . . .

[sweet inlet]

what?
i have been working like this for the past 3 months

[thin aurora]

If your IDE configured? I am really confused by the way your syntax looks

Lack of highlighting, too much highlighting

[sweet inlet]

yeah, i didnt mind that

[woeful leaf]

^ @thin aurora

That’s what I want

[thin aurora]

Does intellisense work when you're asking for Unity related functions in your IDE?

[sweet inlet]

you mean the autocomplete stuff, yeah, it just complains about the way i write variable or method names

[woeful leaf]

Stuff like Start()

[thin aurora]

Then disregard what I said. Your highlighting seems very off, but if your editor can give you errors on wrongly types methods or functions, and can autocomplete, it is probably configured.

[woeful leaf]

He just has a different color for stuff, no?

Which is confusing as all balls but I digress

[thin aurora]

I was put off by the way it's colored in general, but I notice the info above the classes now.

[sweet inlet]

yeah it does all of that, it just wants me to write an _ before private variable names and some other stuff i dont care about

is the look really that off, its the standard intelliJ look

[woeful leaf]

Strange, I don’t think I get prompts for having to write _

[woeful leaf]

And it’s not a local variable if you mean that

[mellow sigil]

It's JetBrains Rider, not VS

[sweet inlet]

yes, i really hate the VS stuff, no offense for anyone who likes to use it tho

[woeful leaf]

Ah that explains it

[peak pivot]

1. You can change void Start() to IEnumerator Start() that way you don't need to start a new coroutine.
2. You appear to unload and load the same scene gameScene is this intended?
3. You don't appear to wait on the async object returned by SceneManager.UnloadSceneAsync()

[woeful leaf]

Probably the majority uses VS

[thin aurora]

Rider does it different. You can configure Visual studio to structure the way you make classes and everything in it, though. I ask it to write private readonly type _field; fields for anything passed into the constructor, for example.

[woeful leaf]

Interesting

[mellow sigil]

You can disable individual style rules in the settings somewhere

[thin aurora]

Pretty sure vanilla VS omits the underscore in this case

[woeful leaf]

Probably

[sweet inlet]

2. was for debugging purposes, doesnt actually do anything, gonna try the IEnumerator

[peak pivot]

Is this object Dont Destroy on Load? Or do you have an instance inside the scenes?

[sweet inlet]

no, its an instance in the scene

[peak pivot]

I don't notice any other issue apart from maybe checking if loadScene.isDone is true when you start the next load that's stuck. since it would just exit the coroutine.

[sweet inlet]

i can tell you what i am doing, i have a title scene, with some settings and a button to start the game, when i start i go to the loadingScene (where this script lives) then i get to the gameScene, when i bet the game i go back to the title scene, trying to start the game again results me getting stuck at 0% progress in the loading scene

[peak pivot]

Also are you running in the editor or in a build? I know that historically loading scenes in the editor can look very different than in builds with where it blocks/update progress.

[sweet inlet]

i can attempt exporting it, havent tried that yet

[peak pivot]

Ok, and this script only exists in the loading scene you load to via your Menu scene?

[sweet inlet]

yes, this script only exists once in an empty object in the Loading Scene, and the loading scene is only getting startet from the title scene

unfortunately exporting also gets me stuck at 0%

interestingly it loads when i dont do it asynchronous

[peak pivot]

Ok yeah, I might be missing something as well here. But I can't spot any errors. And what you say about your structure make sense (assuming all the other loads are LoadSceneMode.Single as well).
If you haven't done it then I would suggest break pointing it, because that might show if there is something weird going on.

(I also haven't done a lot of scene load recently so I might be forgetting some oddity)

[sweet inlet]

this is how i load the LoadingScene

[peak pivot]

@sweet inlet Why Unity version are you using?

[woeful leaf]

why lol

[sweet inlet]

2022.1.18f1

i think that was the latest version when we startet the project

[woeful leaf]

It's not an LTS though

[peak pivot]

Tech releases are supported for a year if I recall correctly?

[woeful leaf]

No idea

LTS is usually more stable though afaik

[peak pivot]

But it doesn't appear to be the latest in the 2022.1.x tech stream

[sweet inlet]

could be that i forgot to update

[peak pivot]

https://unity.com/releases/editor/whats-new/2022.1.24 is the latest. There is also the new 2022.2 tech release.

[sweet inlet]

i am going to try opening it with that version

[mellow sigil]

I'm guessing it's the UnloadScene part. You don't need to do that.

[sweet inlet]

yes, i already removed it

that was for debugging purposes, to check if the scene was loaded without me knowing

[thin aurora]

Well, LTS has longer support. It's not exactly a case of stability

[woeful leaf]

I suppose yea

[thin aurora]

LTS and any other release is as stable as long as it is supported

[woeful leaf]

Fair

[thin aurora]

LTS is just guaranteed to be up to date longer

[woeful leaf]

Righty

When will an LTS of 2022 release actually

[mossy minnow]

yo, im trying to do layer masking with the matrix but it seems to just, not work
i have Enemy/CameraEdge unchecked, my enemy is tagged as Enemy and my colliders are CameraEdge
is there something im missing?

[sweet inlet]

changing to 1.24f1 hasnt helped unfortunately

[peak pivot]

my enemy is tagged as Enemy
By tagged you mean it's in the Enemy layer and not that it has the Enemy tag?

[swift falcon]

https://pastebin.com/3mcvKuMx

is there something wrong with this code? cause when I put blocks like
⬜⬜⬜
⬜ ⬜
⬜⬜⬜
and place the middle block I get weird holes

it's a problem with the mesh.uvs and mesh.vertices and triangles

[peak pivot]

Darn, well I made a minimal setup in 2022.1.24f1 and couldn't reproduce your problem.

[swift falcon]

apparently the triangles array is referencing more vertices than actually exist and the vertices array isn't the same size as the uvs array

[wet pumice]

I'm having a complete brain fart, if I have a unit vector, how's best to detect which quadrant it sits in by the diagonals?

[sweet inlet]

hmmm, is there some setting i changed that could cause this?

[peak pivot]

If you use dot product you can easily check if the vector is within 90 degrees of another vector. So if you check against two vectors that are 90 degree from each other you can locate which quadrant it's in.

The thing to remember is that you get the nearest result regardless of which "side" it's on, that's why you need at least 2 tests.

[wet pumice]

yeah I had thought of a dot setup, just seems like there's a simplet way to do it

x > y works for one diagonal

[mossy minnow]

yup, the layer not the tag

misspoke @peak pivot

[rain minnow]

best choice is dot product or get the angle . . .

[swift falcon]

anyone

[wet pumice]

naturally this would work - I guess as a thought experiment I was wondering if there's a simple solution using linear algebra

[peak pivot]

You might be able to do something like treating the vector as a linear equation and check if the slope is within certain bounds. But dot product is very fast to compute and works regardless of orientation so I would recommend using that.

[wet pumice]

fair

cheers guys

[peak pivot]

Are you using 2D and set the collision matrix for 3D or vice versa?

That's the only thing I can think of.

[sweet inlet]

when i change it to this it loads into the gameScene properly, but i loose my progress bar

[mossy minnow]

don’t think so, i’m in2D but i didn’t see 2 separate matrices

[peak pivot]

If you're using 2D (as in Box Collider 2D) then you should change the matrix in the Physics2D

[mossy minnow]

i’ll check it out

oh man i did not see that lmaoo

[peak pivot]

I would suggest remaking this in a minimal project and see if you can reproduce it there.

[rain minnow]

3d and 2d use different physics engines, so they have separate collision matrices . . .

[mossy minnow]

makes sense

[muted grove]

does unity compile scripts "just-in-time" and does that mean variable name length effects compilation speed

[mossy minnow]

C# isnt interpreted like python so var length shouldn’t have an effect on anything

still keep them short enough to read easily tho ^^

[pine spire]

@muted grove it can use either, though there are platform restrictions, but even then it uses intermediate language and not c# directly

[muted grove]

so variable name length in say, javascript would effect performance?

[pine spire]

I would be surprised if variable lengths actually had and effect. They might be tokenised or something similar.

[muted grove]

more characters to read to tokenize right

yeah but its probably negligible or something, if the projects not super massive?

[pine spire]

I mean with c# everything could be tokenized before it’s compiled to run natively

[sweet inlet]

i guess i just remove the progress bar and call it a day

[pine spire]

And I don’t know how common using jit is anyway

[muted grove]

thanks guys

[swift falcon]

Mesh.vertices is too small. The supplied vertex array has less vertices than are referenced by the triangles array.
UnityEngine.Mesh:set_vertices (UnityEngine.Vector3[])
Chunk:MarchingCubes () (at Assets/Scripts/World/Chunk.cs:136)
Chunk:SetBlockAt (UnityEngine.Vector3,int,bool) (at Assets/Scripts/World/Chunk.cs:229)
BlockBreakingAndPlacing:Update () (at Assets/Scripts/Player/BlockBreakingAndPlacing.cs:46)

Mesh.uv is out of bounds. The supplied array needs to be the same size as the Mesh.vertices array.
UnityEngine.Mesh:set_uv (UnityEngine.Vector2[])
Chunk:MarchingCubes () (at Assets/Scripts/World/Chunk.cs:138)
Chunk:SetBlockAt (UnityEngine.Vector3,int,bool) (at Assets/Scripts/World/Chunk.cs:229)
BlockBreakingAndPlacing:Update () (at Assets/Scripts/Player/BlockBreakingAndPlacing.cs:46)

why does this happen? the triangle to vertices ratio and vertices to UVs ratio is definitely correct

[pine spire]

And anyway - afaik with something like javascript the variables are referenced by memory addresses and even if variable name length affected declaration you would deliberately need to create a scenario where it actually mattered

[swift falcon]

the effect of this is these holes

[hollow cliff]

what downsides will I face in project if I target .net 4.x instead of 2.0/2.1 standard when targeting mobile platforms (or in general)?

[potent glade]

can someone help me with the plugin that I wrote for my webgl app?

[sweet inlet]

ok, i think i found the problem, i just dont konw how to fix it

i am having timer += Time.deltaTime; in my Update() and below that Debug.Log("Timer: " + timer); in unity the timer always shows 0

no idea why, doesnt make any sense whatsoever

it just never goes into the if because timer stays 0 for some reason

[swift falcon]

Hi everyone. I'm trying to make easy to use player effect system for my game, but ... i've encountered some issue which im unsure how to handle. The problem is that supposedly UnityEvents don't fire when i store my effects in non-monobehaviour type class but when i add monobehaviour to it, UnityEvents appear as plain drag'n drop scripts which disables the choice of which functions to fire on event activation.

And here's the code : using System;
using TimeManagement;
using UnityEngine.Events;

[Serializable]
public class PlayerEffect
{
public PlayerEffect()
{
this.timer=new Timer();
this.isActive=false;
}

public string effectName="";

internal bool isActive;

public Timer timer;

public UnityEvent OnEffectStart;

public  UnityEvent OnEffectExit;

}

[sweet inlet]

OH NOOOO, i see why, i put Time.timescale = 0f; at the end of the game, i am so stupid, sorry for wasting everyones time

[rain minnow]

!cs

[tawny elk]

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

class Fluffs : FluffyCat
{
    public void PetCat ()
    {
        Debug.Log ("Petting Cat.")
    }
}

[rain minnow]

how/where are you calling them?

[swift falcon]

Im calling them with Interface function that connects all collectibles. OnCollect() and inside of it i do EffectsManager.instance.playerEffects[chosenID].OnEffectStart?.Invoke()

I've done input system with UnityEvents and it works well but that's a monobehaviour which i guess is the root of the problem

What i've tried is make a wrapper class for UnityEvent stored inside PlayerEffect which derives from Monobehaviour but then again it reappears as plain drag'n drop script in inspector.

I've heard about other types of events but this one can be serialized and that's a huge improvement. For rest of the types i guess i would have to make a custom logic for adding listeners and custom editor etc.

it shouldn't have to be on a MonoBehaviour to run properly. i'd check if i had time

do a quick test. make a serialized c# class with a unity event. create a MonoBehaviour script with the c# class as a field. make a public method on the MonoBehaviour and insert that method in the unity event. invoke the unity in the MonoBehaviour Start method . . .

[swift falcon]

Just tested. And turns out when the event is attached to a class with Monobehaviour it works correctly. What do i do now? If u have any ideas i'll be glad.

[wet pumice]

is there a way to stop unity recompiling every time code changes or when you create a new class and have it only do it on a button press?

[swift falcon]

If i corectly remember there was something in the options try looking for it

[wet pumice]

I shall keep digging

[mellow sigil]

You can set it to compile only on command, but that isn't as useful as you might think. For example if you make that new class you can't attach it to the button before compiling it

[wet pumice]

yeah that's fine, it's just when I'm creating several classes or just tabbing back to the editor to check what something was called or open a file, if I've changed even one line of code, I have to wait the 10 or so seconds for the engine to tell me I'm a good boy

Hi, I'm working with Unity and mySQL db, I made a simple project to test the workflow that get all rows of string and int from table and store a single row with same type.

At the moment, storing data generates the following error log

unity A Native Collection has not been disposed, resulting in a memory leak. Enable Full StackTraces to get more details.

anyone knows how to solve it?

[dusk apex]

You've got to dispose of native arrays if you're using them.

I am getting this error:

EntryPointNotFoundException: GetArgs assembly:<unknown assembly> type:<unknown type> member:(null)

I am using an external function from a java script plugin:

GetArgs : function()
    {
       var str = "A string passed from JavaScript to C#";
        var bufferSize = lengthBytesUTF8(str) + 1; // calculate the size of null-terminated UTF-8 string
        var buffer = _malloc(bufferSize); // allocate string buffer on the heap
        stringToUTF8(str, buffer, bufferSize); // fill the buffer with the string UTF-8 value
        return buffer; 
        }

and in my code this is what I am doing

   [DllImport("__Internal")]
   private static extern string GetArgs();

and in my function:
string abs = GetArgs();

can someone tell me why am getting that error , it's been hours

[fluid moat]

Thanks ill try that :]

[somber nacelle]

not a code question #📲┃ui-ux

[woeful leaf]

Can I not directly update the variable with the GetInt?

Because it doesn't seem to work

[somber nacelle]

there's nothing inherently wrong with that line, however it's really not enough context to know what you are expecting to happen versus what is actually happening

[woeful leaf]

I expect bad to get the value that has been saved beforehand, and I checked, it does have a value

Well, for another variable, but it has the same code as that ¯_(ツ)_/¯

[somber nacelle]

you're assigning the returned value to bad, right?

[woeful leaf]

Yes that's what I'm trying to do

[somber nacelle]

wdym "trying" you are either assigning the value returned by GetInt to bad or not. since you did not show whether you are or not i have to ask

[woeful leaf]

oh

For some reason I thought if you would call it that way it'd assign it, but you actually have to do like bad = PlayPrefs...

Thanks

[woeful leaf]

I assume that's what you mean

[somber nacelle]

yes because the method returns the value. it takes a string for the key name and an int parameter as the default it returns if the key is not found. it's not a ref, in, or out parameter

[woeful leaf]

Yeah that's my bad, I though it was ref or out somehow even though that always has to be explicit

[vestal crest]

NavMesh.SamplePosition sometimes returns infinity? why is that

[wet pumice]

do I have to manually call base.Method() when I've overriden from a virtual method on a base class in order to call it or does it get called automatically? And what if I have a variable of type "base" which I assign a value of type "child" and call the method there?

[somber nacelle]

yes you will need to call base.Method() if you want the base method to be called from the overriding method. and the child's method will be called even if the instance of the child is stored as a "base"

hi, is there any apparent reason why this wouldn't be working? Light.intensity -= Time.deltaTime;

[potent glade]

can anyone help with my post above please?

[wet pumice]

might just be happening really slowly? Light.intensity -= Time.deltaTime * 10000;

see if it's doing anything

[main token]

yeah that's not it

it's behaving really weirdly

[somber nacelle]

see that's something you need to mention when you need help with something. see #854851968446365696 for what to include when you ask a question

[main token]

the intensity value keeps revolving around a certain range, depending on the subtraction value

[somber nacelle]

intensity can also only be between 0 and 8

[wet pumice]

if I don't override the base class method... the base will be called though? (sounds silly to ask now i think about it, ofcourse it will)

[somber nacelle]

yes

[wet pumice]

word

[main token]

Alright so to follow up on this, the lights do not appear to change their intensities, regardless of how much I decrease the value by. Printing the intensity value outputs a 0, but the lights are still very much visible. It's not an issue with referencing the object, as I am able to enable/disable them properly.

[wet pumice]

seems to be something online about render pipelines - you on URP?

[main token]

I am

[wet pumice]

are you able to set the light intensity?

instead of mod it

wait..

that piece of code "Light.intensity -= Time.deltaTime"?

are you running that exact code?

[main token]

I was yeah

setting them doesnt work either

[wet pumice]

that'd be calling the static method on "Light"

[main token]

Light is a reference to the light component

[wet pumice]

no Light is the base class for all lights

it would need to be

Light myLight;
myLight.intensity...

[somber nacelle]

sure but they probably have a variable called Light and are changing the intensity value on that

[main token]

this.Light results in the same thing

[wet pumice]

is that even possible..?

[somber nacelle]

yes

[wet pumice]

wow, the more you know

evidently C++ has rubbed off on me

[somber nacelle]

the only time your variable name cannot be the same as the class name is when it is inside the class you are using. so inside the Light class you couldn't have a Light member, but outside of that you can

[wet pumice]

that makes me uncomfortable

ok well then carry on Crux, mb, still no idea why it wouldn't be working

[main token]

it's so odd, I don't see a reason for it to behave like this

could it have anything to do with the Metal rendering pipeline?

cause I'm on a mac atm

[wet pumice]

out of my depth with that but possibly? idk how maintained iOS builds of the engine are

that sounds

like a pretty fundamental bug though

[main token]

I'll test it on a windows machine real quick

[somber nacelle]

could always ask in #archived-lighting

[main token]

Alright, I'll ask in there

metal was not the issue

[woeful leaf]

Does it matter to do * 0.5 or / 2?

[main token]

multiplication is generally considered to be faster than division

[woeful leaf]

So instead of / 2 I should do * 0.5f here?

[main token]

if you can guarantee that it will be a whole number, then yes

[woeful leaf]

I can

[mellow sigil]

If you multiply by 0.5f it has to cast i to float and then cast the result back to int so it's probably slower

[woeful leaf]

So I should do division then?

[mellow sigil]

to be fair it makes absolutely no visible difference

do whatever is more readable and logical

[woeful leaf]

Also i doesn't have to be a float, I can cast it to int
