[west pelican]

i used a debug log to figure out if the color is changing and it says it is

its changing between red and white but it isn't showing it

[quartz folio]

Do not cross-post. #💻┃code-beginner

[west pelican]

ok

[wispy raptor]

i have a question, is there a way to use something like c#'s Func<T> but serializable?

like a unityevent but that returns something

[leaden solstice]

How’s that supposed to work if you change code

You can make a function ID or enum that you define and call function based on it

[lean sail]

Unity events are already somewhat limited so I dont think this would be too easy to get working

[delicate zinc]

bump (apologies if this isnt allowed lul)

[lean sail]

if it works in 1 case and not the other, id just start debugging everything related to the code youve posted and make sure the values match what they should be.
Try to even recreate it without the moving objects, and see if the raycast hits in the same position

[worn stirrup]

I'm trying to figure out how to make a single manager check a random number, attempt to spawn that number's object, and if it fails, re-attempt other types, but I can't come up with a clean way to put it together and it's getting pretty jumbled right now, does anybody have any pointers for something that handles this?

I can't really figure out how to google for this specific of a spawning behavior

[leaden ice]

what does "that number's object" mean?

Have you somehow associated numbers with objects?

"if it fails" < what could/would cause it to fail?

[dusk apex]

Also, define fails

[lean sail]

sounds like the numbers are IDs, and not everything can spawn in some areas?

[worn stirrup]

Uhhh good questions okay

[dusk apex]

If you're simply trying to not repeat selections or have invalid selections, perhaps remove those selections from the possible choices to be selected.

[worn stirrup]

I'd like for it to have a set of object categories, and it attempts to spawn from each category at random (being able to weight those would be nice, like some categories are still more likely than others), but if it finds out the max limit of that object is in play, or the max for that level has been spawned already, it skips and attempts another

That way the spawner is always consistently trickling in what's necessary until it's done, and it doesn't skip 2 or 3 attempts because it keeps trying to spawn a maxed category already

[leaden ice]

I'd probably do something like:

• pick a random category
• pick a random enemy from the list of valid enemies for that category
• spawn that enemy.

there shouldn't be any retries necessary

because you should remove invalid choices from the pool before picking

[dusk apex]

When you spawn the object, if max has been reached for that object remove it from the list.

[worn stirrup]

Except the list of spawnables is just a range of a resource.load pull e.e I pulled that from a tutorial for spawning random objects of a category

[leaden ice]

and yes weighted random selection is pretty well trod ground

[leaden ice]

So change it.

[worn stirrup]

But like

I don't immediately see a better way to do it that fixes this problem

[leaden ice]

You don't have to stick with what a tutorial taught. In fact tutorial solutions are often suboptimal and not easy to maintain and expand

[dusk apex]

You could have a list representing all the resources and another representing all currently available resources

Retrying is not preferable

[leaden ice]

Create a better data structure. For example use ScriptableObjects for the categories and each category object can store the list of objects it contains.

anyway i have to get some sleep

see ya

[worn stirrup]

My issue with ScriptableObjects is being able to pull and use their data at runtime, because I end up having to generate something that clones the SO's data into an empty GO in the scene to be referenced

I've never figured out how to put a bunch of data in a ScriptableObject and reference that data from an object in-scene without cloning each varaint of the ScriptableObject into an in-scene reference, and that feels like a junky way to get around it

So I'm trying to avoid the ScriptableObject problem, and I think I'm just hitting that block

It's all too hard-coded now

[dusk apex]

Either way, retrying is not preferred

[worn stirrup]

What exaclty do you mean by retrying?

[dusk apex]

This

2 or 3 attempts

[worn stirrup]

Yeah no I definitely want to get around that

But this is going to take a lot more forethought than I have available tonight 😅

So I'll think and plan that out and come back later when I'm implementing

[dusk apex]

Instead of trying to not generate the invalid number, consider changing the collection to not have invalid entries

[worn stirrup]

Yeah that makes sense, that's what Praetor had said too at some point, that's a good appraoch

Thank you :3

[leaden ice]

yo udo't need to clone anything?

Just reference it directly

especially if it's not mutable

like in this case

but yes think of them as data stores

they don't need to be the final runtime data structure you're dealing with

just a basis for static information to build that with

[worn stirrup]

Yeah that's exactly how I'd use them, I have a lot of intermingling physics and objects that should come from others, so I need to set up all the relationships of what each thing has, their mass ranges, speeds, and resources provided when obtained

[elder flax]

im having an issue with textmesh pro

it was working fine earlier but I built my mac version to Intel instead of Intel+silicon and now all my tmp text is invisible in the build

the thing is, the text is only invisible if it was active on the scene start

if it was inactive or instantiated after scene start its fine

and it only happens when i enter my play scene, my mainmenu scene is fine

should i reinstall tmpro or something

the only thing i did that might have affected it is add standard (specular) to the included shaders

[wicked cape]

(Help) how i can parse this json file in unity https://qa2.sunbasedata.com/sunbase/portal/api/assignment.jsp?cmd=client_data

[leaden ice]

You'd have to use Newtonsoft JSON since the "data" section is a Dictionary which isn't supported by JsonUtility

[wicked cape]

okay thanks

Hi guys , upon uploading my unity android build to google play i get a warning
"Androidx.fragment:fragment has reported version 1.0.0 as outdated" has anyone seen this error? How to resolve?

[bleak thorn]

Hi how to change shooting cargo, to actual direction of rocket (not only up?)

[prime sinew]

Use transform.up

[bleak thorn]

thank you

[prime sinew]

The rocket's transform btw

[void remnant]

Hello, is there any difference between StopCoroutine(IEnumerator) and StopCoroutine(Coroutine)? If yes, then what's better to use?

[tired elk]

https://docs.unity3d.com/ScriptReference/MonoBehaviour.StopCoroutine.html

[prime sinew]

@void remnant
I personally only use the Coroutine one, because most times I want to stop a specific instance of a Coroutine

I dont know if the IEnumerator version lets you do that

[tired elk]

It may stop the first or all coroutine which comes from the IEnumerator since it can be linked to multiple Coroutine instances.

I prefer the 3rd option too since it's an instance and you have better control of where and when it's assigned

[void remnant]

Ok, thank you very much

[cinder oriole]

Hello guys i have a bug currently ongoing in my game and i've been trying to find out whats wrong for the past 4 hours,

so basically i instantiated a bunch of items from a list of an item scriptableobject, and then i destroy it via script, and the next time i instantiate a new set of items, for some reason the old destroyed items appeared once again in the scrollview please help

also for some reason my game has invalid AABB errors idk what that means

[tired elk]

What's the code for the instantiation ?

[tired elk]

OK. What can happen is you're disabling the object that holds all instances before the destruction method runs.

[tired elk]

FindGameObjectsWithTag() only work fork active objects

[cinder oriole]

i call destroy from here

[cinder oriole]

but in my hierarchy they've all been destroyed as well

if u watch the video, u see then i click 'continue' button, all the gameobjects inside the panel gets destroyed

but for some reason the next time i instantiate new items, the old ones magically reappear

[tired elk]

You're right, my bad. currentItemScene.itemsSO is fed at some point ?

[regal flame]

are you never removing the items from currentItemScene.itemSO?

[tired elk]

Like, is there something that fill this list/array ?

[cinder oriole]

its fed manually through an inspector

[cinder oriole]

umm no its always there

oh should i try and remove everything from the list and see if thatworks?

so destroy the game objects and remove everything from the list

[tired elk]

Well, you could try. The foreach may run longer than you think.

[cinder oriole]

hmm alright, thanks so much for the help guys, i'll get back here if it didnt work

[regal flame]

set a debug.log in the foreach with the gameobjects name (or any unique identifier) and you should see that you are instantiating more than you intend on, probably atleast

[cinder oriole]

i did, and the items that magically reappeared wasnt included in the debug.log

so somehow they just ghosted their way through the debug.log and just reappeared in the scrollview

[tired elk]

Now this is weird

[cinder oriole]

sorry, how do i remove all elements from a list via script?

can i use RemoveAll()?

[regal flame]

List<> list; list.clear();

[cinder oriole]

okay thanks

OMG IT WORKS

thank you brother

i had this going for 5 hours

i love u guys

[regal flame]

glad you solved it 😄

[tired elk]

Nice ! Well played 🙂

[tired elk]

On this one particular issue, you may have a collapsed console, and duplicates were probably stacked

[cinder oriole]

oh right..

but anyways i guess i'll stick with the clearing list for now

but yea i did try to run the old code again without a collapsed console, and did Debug.Log(item.name) on the foreach loop, and turns out it did instantiate the old items @tired elk

but thats weird, can you think of any workaround if i dont want to clear the list but instead just destroy the gameobjects?

i mean yea clearing the list solved my problem but what if i wanted to revisit it in the future

[tired elk]

The list is fed with new stuff at some point in your code. You should find where this happens.

If the inspector was the only place, it wouldn't do this.

[regal flame]

you probably just don't want to instantiate it all from the same list, separate into different collections, or just be mindful of what you populate that list with

[tired elk]

Do you have like a "Get current item scene" method ?

[cinder oriole]

basically i have an Item script which isnt a monobehavior and just holds:
-ItemSceneID
-List of Item Scriptable objects

and then from another script i have a list of <Item> where then i can add them manually from the inspector

its not from the same list, just from different instances of a single Item script

[tired elk]

If you're unsure, you could right click itemsSO in your IDE, click "Find all references" and check if you have Add() or AddRange() called on it somewhere in your code

[cinder oriole]

hmm

okay

let me chcek

whatever i'll just stick with this for now im too tired for this

[idle stratus]

I'm trying to refer to a canvas gameObject inside a prefab, but whenever i turn it into a prefab, it clears the field and when I try to reassign it it shows this

inside the script Game Logic is marked as a GameObject

should I just use Find()?

[prime sinew]

what do you mean turn it into a prefab..?

[idle stratus]

drag it in the assets folder

[prime sinew]

where is this canvas gameobject

[idle stratus]

Scene>EmptyGameobject>canvas

the empty gameobject is to organise stuff

[prime sinew]

so just to be clear, you have another object in the scene(let's call this ObjectA) that has a reference to this canvas object

and you want to turn ObjectA into a prefab

[idle stratus]

yes

[prime sinew]

prefabs cannot have references to scene objects

[idle stratus]

oh well that clears it

[prime sinew]

you need to assign it at runtime

[idle stratus]

so?

[prime sinew]

usually the spawner of the object should hold a reference to this canvas object

then it passes this reference to the spawned prefab instance

[idle stratus]

the spawner is the canvas

[prime sinew]

okay, so pass itself into the spawned object

using a function or something

https://unity.huh.how/programming/references

see Dependency injection

[meager wasp]

Hello, I'm currently trying to get dual monitors to work. I read https://docs.unity3d.com/Manual/MultiDisplay.html on how to activate the screen and that works just fine but it activates on my main monitor and I can't get the normal Window options to. Move it to 2. Monitor. Is there some way to activate it on 2. Monitor directly or get the normal window options back to. Move it myself?

[idle stratus]

is it even easier if object a is a child of the canvas?

[cinder oriole]

does anyone know what this error is and if it'll ruin my build if i decide to go on with it

[prime sinew]

idk about easier. it's what you want

[prime sinew]

ask in #💻┃unity-talk

[agile temple]

Hello, I have issue with gun hitting my enemies. Main problem is I look for enemies through box collider but I have there some spread of bullets to make my game little bit random but I deal damage only if I hit in the collider and if I do bigger collider it will damage too many enemies. Also I cant use bullet trail beacuse it has problem with gameobject and my enemies are some different type. Here is my code https://pastebin.com/qFHqJf3Y

[prime sinew]

all you need to do is just have a function that will take in the canvas reference as a parameter and use that to assign to the prefab's variable that holds the reference. That's all

[idle stratus]

will the program recognize that the prefab has this variable?

[prime sinew]

... if you access the component of the prefab.. sure?

[idle stratus]

aah okay i get it

thanks

[rocky helm]

If I am going to be calling GetComponent<T>() a lot in a frame, would it be faster to have a single script already holding public variables for those components, or would it have the same effect as just calling GetComponent for each of the components I need?

[regal flame]

If you can avoid GetComponent then do so in my book

especially if doing it often

[tired elk]

Fastest would be to cache the result of GetComponent<T>() in a logical place. If you only need access to this component in a single class, you should cache it inside said class.

[lethal plank]

guys will List.AddRange(AnotherList); affect to "AnotherList"?

[hexed coral]

No, it only mutates "List"

[lethal plank]

ok thank you

mine are somehow affect to "AnotherList"

[hexed coral]

If that's happening it's not on that line of code, you should consider showing us how the rest of your code looks like

[lethal plank]

i will figure it out first

if i cant find any then i will ask

[rigid island]

probably because they contain the same reference types as item?

[lethal plank]

hmm its happening just like i let List = AnotherList but only affect the part i added

[hexed coral]

Oh

[lethal plank]

when i add something in List it not add to AnotherList

[hexed coral]

You are mutating the same object

[lethal plank]

ah

[hexed coral]

List = AnotherList makes both point to the same reference

[oblique spoke]

What are you storing in those lists?

[hexed coral]

If you want to clone a list:
List = new List(AnotherList)

[oblique spoke]

AddRange should also be fine

[lethal plank]

one is for working and on is based

[hexed coral]

Could you rephrase that? I don't understand

[lethal plank]

oh sorry

[oblique spoke]

Structs and other value types are cloned, but class references will still point to the objects living elsewhere

[lethal plank]

"List" is a list im using it for working
"AnotherList" is the object i use it for reference

if i using right word

[hexed coral]

We can only understand what you're talking about if you share your code

[lethal plank]

if you could understand it xd

https://hatebin.com/eaerjknozl

here

when i delete line 31 it will not affect data.AttachmentSlots

[sudden meadow]

How do I make unity cease adding tons of namespaces automatically?

[lethal plank]

bro too lazy XD

[gray thunder]

It either adds the basic namespaces

Or requires you to add the ones you need

[sudden meadow]

it doesn't. it adds tons of things it thinks i need all the time

for example probuilder for "Sprite"

[oblique spoke]

Unintended includes are probably coming from typos that you aren't undoing

[sudden meadow]

well, regardless, no way to make it less aggressive when it comes to this? it likes making edits to shader code too without asking

[lethal plank]

this line is for clean slots

[rigid island]

this comes with drawback of having none show up 😦

[hexed coral]

This is clearly a reference vs value type problem, AttachmentSlot is likely a reference type so editing an object will also affect any lists that object is on

[gray thunder]

afaik you can right click them and click on something like 'remove all unused namespaces'

something along those lines

[sudden meadow]

@rigid island i wouldn't mind adding a few namespaces

[rigid island]

also its not unity adding it, and its VS

[oblique spoke]

I'm sure there is a setting for this somewhere

[late lion]

Unity doesn't modify your scripts or shaders unless it's auto upgrading a deprecated function.

[oblique spoke]

Yea pretty sure this is a feature in VS

[rigid island]

there is to turn it off but you can't like "turn down to mild" or something, i don't think

[hexed coral]

Please take some time to read about reference types: https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/reference-types

[lethal plank]

alright

[lethal plank]

i see
so there are no way to clone or copy it?

[rigid island]

https://www.geeksforgeeks.org/shallow-copy-and-deep-copy-in-c-sharp/

see this

[lethal plank]

ok

[lethal plank]

thanks

[carmine prism]

I'm using the following script to move a rigidbody player, but when checking velocity.magnitude of the rigidbody, it looks like the rigidbody has higher velocity whenever it goes up a slope.
Any ideas what i'm doing wrong?

private void MovePlayer()
{
    moveValues = playerControls.Move.ReadValue<Vector2>();
    if (isGrounded && moveValues == Vector2.zero) { EnableFriction(); }
    else { DisableFriction(); }



    float calcedMovementSpeed = walkSpeed;
    if (isSprinting && moveValues.x == 0 && moveValues.y > 0) { calcedMovementSpeed = sprintSpeed; } // SPRINT IF GOING FORWARD AND NOT GOING SIDEWAYS
    if (isCrouching) { calcedMovementSpeed *= crouchSpeedModifier; }

    Vector3 movement = (transform.right * moveValues.x) + (transform.forward * moveValues.y);

    movement *= calcedMovementSpeed;
    movement.y = rigidbody.velocity.y;

    rigidbody.velocity = movement;
}

specifically: higher the slope angle, higher the velocity

[hexed coral]

Also, if you're cloning a class all the time there's a good chance it should be a struct instead, though be careful dealing with structs, they have a lot of small rules that might not be intuitive at first glance

[static matrix]

is it possible to do occlusion culling if I cant do any baking?

like is there a builtin way to do it

[swift falcon]

My breakpoints don't seem to be working, anyone know why?
I feel like I remember getting more feedback that I activated a breakpoint, more things going red or something

I am in debug mode in Unity

[knotty sun]

you are either not attached or not in play mode.
Notice 'Attach to Unity' at the top

[swift falcon]

Ah right that worked thanks

[glossy ledge]

So if anyone has run into a similar issue, this is how I solved it.

First I added this to the Android Manifest :

[round creek]

anyone have any idea as to why my trail flickers at the end? for context, player moves and camera follows.

[leaden ice]

how is your player moving

[round creek]

rb.moveposition

[leaden ice]

from where?

Update? FixedUpdate?

[rigid island]

only recorded like a split second..nice

[round creek]

fixedupdate

[leaden ice]

Do you have interpolation enabled on the Rigidbody?

[round creek]

no

[leaden ice]

turn it on

[round creek]

k

still the same

btw the trail renderer is attached to a child object of the player

[leaden ice]

should be fine

[rigid island]

the greens look also choppy but hard to tell on a 1 sec video

maybe its the cam parenting

[leaden ice]

how is the camera moving

[round creek]

nah i just have rlly low frame rate when recording

[leaden ice]

Once you have rigidbody interpolation enabled, the camera should be following in LateUpdate

(or ideally with Cinemachine)

[round creek]

following player rb's position in update

[round creek]

okay

[leaden ice]

don't use the RB position

use the transform position

rb position is not interpolated

transform position is

also yes move to LateUpdate

[round creek]

alr lemme try. if u don't mind, why exactly is my problem happening? is something out of sync or?

[leaden ice]

yes the physics updates are not in sync with the frame updates

hence the need for interpolation

and once interpolation is on you need to just make sure your camera is following the interpolated position

[round creek]

k, so three things: interpolate rb, use player transform for camera follow instead of rb, and update cam pos in lateupdate?

[leaden ice]

That's my recommendation yes

lmk if it helps

[rocky helm]

So, I'm doing rigidbody.position = ...; but there seems to be a chance of this sometimes not moving the rigidbody at all which is quite odd. The rigidbody is CollisionDetectionMode.ContinuousSpeculative; and RigidbodyInterpolation.Extrapolate;. I am also changing rigidbody.rotation and transform.parent on the same frame, in case that matters. Also, I used to do this with around 100 objects in one frame and when it happened, it happened to all of them and it is still like that. I am unable to give logs of the rigidbody position after setting it when it glitches, because every god damn time I put a Debug.Log() anywhere it just completely stops happening, but I can ensure you that the position it is being set to is static and definentely not 0,0,0 where the pieces are being set to.

---

I have a theory that this could maybe be related to Update and FixedUpdate firing in a certain sequence which makes this happen for some reason??

Also google hasn't been of much help for me in this and this has been a problem for more than a week now

[round creek]

lmk if it helps

[leaden ice]

If you are directly setting RB position the collision detection mode and interpolation mode are irrelevant

those only apply when using velocity or adding forces

[rocky helm]

Yeah, I just added them in case they help, since I am not sure what is causing my problem

[leaden ice]

perhaps an animator? Or some other code setting the position, or the physics simulation fighting with you?

[rocky helm]

No animations/animators yet, no other code is setting the position either. It is probably the physics simulation, yet I don't understand why, and also the fact that printing the rigidbody position right after setting it "fixes" the problem just makes me really confused

Should I head to #archived-code-advanced with this?

[lethal plank]

Sound fun

[modern creek]

When I use a TileMap and Grid, I don't see any gameobjects for each of the sprites. If I wanted there to be some sort of underlying data structure or game object.. do I have to use the GemBrush or something else to create the tiles programmatically..?

Or am I approaching this the wrong way - should I create my underlying data structure and optionally my game objects, then render the tilemap as a "view" of those objects? The tutorials I see look like they do something like create an int[,] and populate it, then populate a tilemap based on the values in their array

(And I'm assuming then that user input is "collected" by unity but then I'll have to flow it back to my objects - ie, by overriding TileBase and implementing click handlers)

[leaden ice]

can you show your code?

[twilit canyon]

Hello, I made a question in unity forums but didn't got help, only one person answered without even bothering to read the post, then i made a post in stack overflow, got 2 comments of people that didn't bother to see everything and a downvote, last time i got a downvote no one answered after, if anyone can help me i would appreciate it, all of the info about my problem is here: https://pastebin.com/4U0YcDJW

[leaden ice]

what is the InputManager script?

[twilit canyon]

new input system

but that works fine

[leaden ice]

I mean it's a custom script of yours, that's not a built in part of the input system.

can you show the code for it

[twilit canyon]

ok

[leaden ice]

also whatever other components you have

also AddForce should not be used in Update

[twilit canyon]

ik

[leaden ice]

it belongs in FixedUpdate

[twilit canyon]

i changed it and didn't work

[elfin quest]

I'd change the movement to movement = rawmovement * speed * Time.fixedDeltaTime

[rocky helm]

        }
        Vector2 medianCenter = addedPoints/polygon.Length;
        rigidbody.position = relativeTo.position + relativeTo.right * medianCenter.x + relativeTo.up * medianCenter.y; // <--
        // relativeTo is the transform where I want to create the shard
        Debug.Log(rigidbody.position); //Adding BOTH of these makes the glitch stop happening
        Debug.Log(relativeTo.position);
        //The script goes on for a bit from here, but I believe nothing it does has to do with setting the position, it just creates a mesh and assigns it to the mesh filter of the object

[elfin quest]

I have never worked with addForce, but whould you not be multiplying by the fixedDeltaTime (when using it on FixedUpdate)

[leaden ice]

why

no

you should never multiply forces by deltaTime or fixedDeltaTime

nor should you call it in Update

[leaden ice]

anyway your issue is just that your force is too small to overcome friction

notice that when you make it huge it goes way out of the world

just set it somewhere in between

and put it in FixedUpdate so it's consistent

[twilit canyon]

but if i decrease friction or make the force too big the object no clips or goes flying to narnia

[leaden ice]

make it bigger, but not too big

mama bear force

[twilit canyon]

i tried making it bigger

there is no somewhere in between

or is too big or is too small

[elfin quest]

Ah, mb, never worked with addForce, as stated. And my dumb ass didn't see that the rawMovement was a Vector2 Forgor everything I've said

[leaden ice]

putting it in fixed update will help alot

otherwise it will be very inconsistent

[twilit canyon]

1

[twilit canyon]

It is

someone already told me

is not working

[leaden ice]

can you show the inspector for the gorund

[twilit canyon]

ok

[leaden ice]

is it uses any custom physic materials etc

[twilit canyon]

(i'm using probuilder)

here is a video of the behaviour using fixed update

[leaden ice]

idk something is definitely odd in your scene

can you make a new scene

[twilit canyon]

ok

[leaden ice]

put just the player object in it

and a simple floor

and see how it behaves

[twilit canyon]

i made a new scene

it works fine

it has the movement i'm looking for

but why is the other scene failing?

[leaden ice]

something you have in the other scene is messing it up

some other script or something

[twilit canyon]

i have 3 other scripts

[leaden ice]

maybe on the MatchManager or CameraLimits or something

[twilit canyon]

camera limits?

oh

[leaden ice]

just pointing out objects in your scene that might have scripts on them

[twilit canyon]

match manager only has score values

i'll add it to the new scene

nothing

is the camera limits

that's causing it

[twilit canyon]

thank you so much

[rocky helm]

Also I noticed that it only stops happening when both of the logs are there

[candid forge]

do any of you know how i could go about generating terrain like this from perlin noise?

[rocky helm]

https://www.youtube.com/watch?v=vFvwyu_ZKfU&t=478s Perhaps this video will be of help

[candid forge]

i've been racking my brain on how to generate procedural meshes from points but i'm wondering if i'm looking in the wrong place

[candid forge]

these don't work because i want layers, not a continous mesh

[rocky helm]

You want these layers to be different objects or one object?

actually doesnt matter much

You could set up what was shown in the video, but snap those points on a grid on the y axis

[candid forge]

yeah, if i think about it, i can make it go down 90 degrees at certain points

i will try thank you

[rocky helm]

@leaden ice ?

[leaden ice]

does adding Physics.SyncTransforms() in place of those logs also fix it?

[rocky helm]

Nope.

Please don't tell me this is a god damn Unity bug again. I already had to work with one of those I found before.

Let it be my stupidity or something else

[bleak abyss]

anyone plz help

[rocky helm]

!vscode did you follow the instructions?

[bleak abyss]

which instructions

[rocky helm]

!vscode

[tawny elk]

Visual Studio Code guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

https://on.unity.com/vscode

[rocky helm]

wait what

!vs

[tawny elk]

Visual Studio guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

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

[rocky helm]

I don't remember which of these, if these are correct aaaa

[bleak abyss]

do you know what the error is?

[rocky helm]

It seems like an unsupported format that you have, as the warning suggests.

[rocky helm]

There we go, did you follow this, or something like this to set up vscode?

https://code.visualstudio.com/docs/other/unity

[bleak abyss]

nope the vscode suggested to install c# kit so i installed it

[rocky helm]

Then try to follow that guide too, and see if you haven't done some of the things there and then do them

[bleak abyss]

ok thanks

In the foreach loop, I need to return a string for a string variable inside the class I created. What should I add to foreach (string s in thisLevel.AllObjects[number].objectname)

[leaden ice]

what are you trying to do? What do you mean by return a string for a string variable in the loop

Do you mean return or just that you want to iterate over them?

e.g.

foreach (var obj in thisLevel.AllObjects) {
  string name = obj.objectname;
}``` ??

[brittle haven]

'objectname' is a class and it has a string in it. I want to return a string for the string inside it in foreach loop

[modern creek]

I have a 100x100 flat-top hex tile, and when I create and use a tilemap with the default swizzle (YXZ) it looks correct, but changing it to XYZ breaks it. I'd like to use XYZ because it makes more sense to my programmer brain. Any idea what I'm doing wrong? Do I need my assets to be "pointy top" even though they're flat top when swizzled to XYZ?

[lapis ruin]

Currently I have a whole Rigidbody based first person movement system, and the only problem with it is that it struggles to go up any drastic change in height such as a stair. To counter this, I want to make the player sort of always keep a .5 unit offset from the closest ground to their feet (so floating, pretty much) with the use of a Raycast detecting the ground below them. The way to do this would be to continuously change the Y of the player from the Y of the point of raycast collision plus that .5 unit offset mentioned previously by changing the player's transform. So I did this, it works fine. But is there any way I can fix the jittering?

[lucid valley]

you are going to have to expand on why you need the loop

are you trying to add them all together?

or do you only need one of them?

[leaden ice]

ok so... what is the string variable's name then? I was merely basing my response of your code example and I cannot see your code so I have no idea other than what you have given me

simply access the thing you want to access with .whateverTheVariableNameIs

[brittle haven]

foreach (string s in thisLevel.AllObjects[number].objectname)
I want to return a string in [System.Serializable] public class ObjectName { public string objectNameName; public float delay; } for 'objectNameName' here

[somber nacelle]

is objectname a variable of type ObjectName

[brittle haven]

AllObjects has ObjectName inside

[brittle haven]

yes

[lucid wigeon]

[SerializeField] InventoryItem? selected;
Are nullable types like this OK or not? I cant even assign NULL in the Editor. But I can via code. How else would you store such variable? selected = null; makes sense when nothing is selected...

[somber nacelle]

then you just use the . operator to access one of its public members

[leaden ice]

ok so...

foreach (var obj in thisLevel.AllObjects) {
  string name = obj.objectname.objectNameName;
}```

[somber nacelle]

but your loop should be ObjectName s in whatever, not string s

[leaden ice]

I don't know why you have such a ridiculously named class and variable but here we are

[brittle haven]

but objectname is list

[sage latch]

The inspector will create an instance for you

dont serialize it

[leaden ice]

no it's not

[sage latch]

if you really need to, then instead have a bool that tracks if you have a selected item

[somber nacelle]

at this point i'd recommend you go through some basic C# courses to learn how to use lists and loops. there are some great beginner courses pinned in #💻┃code-beginner

[lucid wigeon]

How would I see what is selected then?

[leaden ice]

anyway if you have all these variables with different types and you want us to answer a question about them you'd have to actually show us the code that defines the variables otherwise we're just guessing

[sage latch]

A UI element or custom inspector

[lucid wigeon]

But if I have a bool, and non-nullable field as well, something would need to be assigned even if it doesn't make sense

[sage latch]

just the default value works fine

[lucid wigeon]

Ok

[brittle haven]

I know about lists, arrays, classes in C# but still couldn't solve this problem

[leaden ice]

#archived-code-general message

[somber nacelle]

you've not really described your problem in a way that seems clear. you also are apparently not understanding how a foreach loop works

[lucid wigeon]

I suppose I could make a default item like "hand" in my case, and check for item.type == hand instead of item == null

[sage latch]

Don't love that

[lucid wigeon]

why not?

[sage latch]

Feels over-complicated, a nullable field works fine with just a bit of extra work

[brittle haven]

[System.Serializable]
public class LevelSettings
{
    public string LevelName, LevelAuthor;
    public float MusicBpm, IntroTime;
    public int LevelDifficulty;
    public List<Object> AllObjects;
}
[System.Serializable]
public class ObjectName
{
    public string objectNameName;
    public float delay;
}
[System.Serializable]
public class Object
{
    public float time;
    public ObjectSettings objectSettings = new();
    public List<ObjectName> objectname = new();
    public Add add = new();
    public Vector3Change vector3Change = new();
}```
thislevel is a LevelSettings
```cs
foreach (string s in thisLevel.AllObjects[number].objectname)```
how can i fix this

objectname was a string but now it's a class

[sage latch]

Also easy to mess up. Accidentally set an item's type to hand? Now everything about that item is broken and you have a hard issue to debug

And its not obvious what "hand" means. You could name it None or something but that might be mistaken for a generic item without a category

[somber nacelle]

the local variable created in the foreach loop should be of type ObjectName not string. or just use var like praetor suggested because that will be the correct type no matter what (the correct type being ObjectName in this case)

then, as has already been pointed out, you can access one of the ObjectName's public members using the . operator

[brittle haven]

ok, i solved the problem. so what should i do if i need to use string in foreach

[knotty sun]

foreach (ObjectName objName in thisLevel.AllObjects[number].objectname) string s = objName.objectNameName;

[hollow hound]

Why objects have different behaviour dependent of the SerializedField and how to "fix" this?
Simple example:

Component on the prefab in prefab explorer

public class MyPrefab : MonoBehaviour
{
  [SerializeField] List<int> _nums = new();

  public void Add()
  {
    _nums.Add(1);
  }

  public void Log()
  {
    Debug.Log(_nums.Count);
  }
}

Component on the object at the scene

public class Spawner : MonoBehaviour
{
  [SerializeField] MyPrefab _prefab;
  MyPrefab _prefabInstance;

  void Start()
  {
    _prefabInstance = Instantiate(_prefab, transform);
    _prefabInstance.Add();
  }

  void Update()
  {
    if (!Input.GetKeyDown(KeyCode.Q)) return;

    var secondPrefab = Instantiate(_prefabInstance, transform);
    secondPrefab.Log();
  }
}

If _nums is SerializeField, I'm getting 1 after pressing Q. If it isn't, I'm getting 0.
Why?
Seems like SerializeField shouldn't change the behaviour that way.
The result is also 1 if _nums is public or [HideInInspector] public. But it's 0 if _nums is private without SerializeField.

[earnest gyro]

Merging two custom Memory objects

[leaden ice]

Instantiate copies serialized fields
It doesn't copy fields that are not serialized

that's one of the main points of serialization

[somber nacelle]

just FYI HideInInspector does not prevent it from being serialized, just from being shown in the inspector

[leaden ice]

[NonSerialized] would prevent it from being serialized

if you wanted that

[hollow hound]

What if I want Instantiate to copy values but don't want field to be visible in editor nor be public?

[leaden ice]

[HideInInspector] and private

[hollow hound]

Not working.
[HideInInspector] private List<int> _nums = new();
Still getiing 0

[somber nacelle]

and SerializeField

[leaden ice]

yeah mb forgot about SerializeField

[hollow hound]

Thanks!

[lucid wigeon]

Is private required? I thought that was the default

[hexed geode]

How do I let my players choose a file from their computer without using EditorUtility?

string path = EditorUtility.OpenFilePanel("Select image", "", "png");

[leaden ice]

private is not required

[somber nacelle]

if no access modifier is specified for a field, property, or method, then yes. private is implied. it's typically better to be explicit though and you'll see that many devs tend to be explicit with access modifiers

[leaden ice]

either:

• invoke the native file explorer for the current OS (with a native code plugin)
• find a file picker asset on the asset store
• build your own file picker

[hexed geode]

alright i'll look on the asset store

[gritty hazel]

Does anyone have high latency when running Microphone.Start() on Oculus?

[hexed geode]

I imported SimpleFileBrowser into my project from the asset store, but doing this doesn't allow me to actually use that namespace, even though Unity shows no errors. Haven't worked with many custom script assets so I'm not sure how I'm supposed to make it work

[somber nacelle]

if you don't see any errors in the unity console after saving this then you need to regenerate project files

[hexed geode]

im not sure exactly what you mean by that or how to do that

[somber nacelle]

in the external tools settings in preferences

might also need to restart visual studio after regenerating

[jolly stratus]

Can anyone here who uses photon pun2 public sever for testing tell me how much ping they were getting? I am in one of the server countries and I am getting like 200ms, is it always this bad in public and gets better when you buy premium or what?

Well okay, if anyone answers me, please tag so I can see it later

Guys. I'm trying to save a few assets created at runtime, and link them to a GameObject as a prefab, but every time I exit the play mode and place the prefab at my scene, all references are broken. This is the code I'm using:

        [MenuItem("ACKNEX/Generate Lightmap")]
        private static void GenerateLightmap()
        {
            var meshFilters = new List<MeshFilter>();
            foreach (var group in World.Instance.AllWallsByName)
            {
                foreach (var wall in group.Value)
                {
                    meshFilters.Add(wall.WallMeshFilter);
                    meshFilters.Add(wall.GapMeshFilter);
                }
            }
            foreach (var group in World.Instance.AllRegionsByName)
            {
                foreach (var region in group.Value)
                {
                    meshFilters.Add(region.CeilMeshFilter);
                    meshFilters.Add(region.FloorMeshFilter);
                }
            }
            var prefab = new GameObject("Prefab");
            prefab.hideFlags = HideFlags.DontUnloadUnusedAsset;
            for (var i = 0; i < meshFilters.Count; i++)
            {
                var meshFilter = meshFilters[i];
                var newGameObject = Instantiate(meshFilter.gameObject);
                newGameObject.transform.SetParent(prefab.transform, true);
                meshFilters[i] = newGameObject.GetComponent<MeshFilter>();
            }
            for (var i = 0; i < meshFilters.Count; i++)
            {
                var meshFilter = meshFilters[i];
                if (meshFilter.mesh.vertexCount == 0 || meshFilter.mesh.triangles == null || meshFilter.mesh.triangles.Length == 0)
                {
                    continue;
                }
                // some geometry is made up of quads, this is needed to unwrap them
                var triangles = new List<int>();
                for (var j = 0; j < meshFilter.mesh.subMeshCount; j++)
                {
                    meshFilter.mesh.GetTriangles(triangles, j);
                    meshFilter.mesh.SetTriangles(triangles, j);
                }
                if (!Unwrapping.GenerateSecondaryUVSet(
                        meshFilter.mesh, new UnwrapParam()

                        }
                    ))
                {
                    Debug.Log(meshFilter.gameObject.name + " failed");
                }
                meshFilter.gameObject.isStatic = true;
            }
            AssetDatabase.StartAssetEditing();
            foreach (var obj in World.Instance.CreatedObjects)
            {
                string ext = null;
                if (obj.GetType() == typeof(UnityEngine.Material))
                {
                    ext = "mat";
                }
                else if (obj.GetType() == typeof(UnityEngine.Texture2D))
                {
                    ext = "texture2D";
                } else if (obj.GetType() == typeof(UnityEngine.Texture2DArray))
                {
                    ext = "texture2D";
                }
                else if (obj.GetType() == typeof(UnityEngine.Mesh))
                {
                    ext = "mesh";
                }
                if (ext != null)
                {
                    AssetDatabase.CreateAsset(obj, $"Assets/Lightmap/{obj.GetInstanceID()}.{ext}");
                }
            }
            AssetDatabase.StopAssetEditing();
            AssetDatabase.SaveAssets();
            AssetDatabase.Refresh();
            PrefabUtility.SaveAsPrefabAsset(prefab, "Assets/Lightmap/Prefab.prefab");
        }

Do I have to save the Prefab before the Assets, or am I doing something wrong?

[naive swallow]

Is there a decent way to get the viewport position of a UI element on an overlay canvas without needing to manually un-transform all the parents' positions?

[slim gate]

protected virtual void Start()
    {
        ...
        if (x) return;
        ...
    }

protected override void Start()
    {
        base.Start();
        
        Debug.Log("X")
    }

Probably a stupid question but just to make sure: Will the Debug.Log be called in the inheriting class if the base returns or no? I assume it will still be called

[naive swallow]

Just running screenToWorldPoint on the object's .position isn't fully accurate. I'd like to get the viewport position of the rect transform's pivot so I can convert that into world space more accurately.

[robust dome]

Collider2D[] results = Physics2D.OverlapCircle(transform.position, circleCollider.radius, yourLayerMask);
Debug.Log(results.Length);

[naive swallow]

The documentation you sent is for PhysicsScene2D.OverlapCircle, not Physics2D.OverlapCircle:
https://docs.unity3d.com/ScriptReference/Physics2D.OverlapCircle.html

There isn't a form of this one that has a list of colliders as the third parameter

Took me an astonishingly long time to figure that out as well

I had to actually plug the code into VS and see what it suggested to realize it wasn't the same

[robust dome]

good catch

[lean brook]

how to reach a canvas' child object's position in script? i've tried plenty of things but none of them worked.

[void sundial]

Has anyone here experience with mlagent scripting?

If so do dm me.

[robust dome]

@lean brook GetChild(index) then GetComponent<RectTransform>()

[rigid island]

"plenty of things"

sounds ominous

[rigid island]

#archived-machine-learning

[rigid island]

fun fact: You can just cast (RectTransform)transform

[naive swallow]

I am trying to draw a line renderer pointing from one UI element to a specific spot in the scene. This test version should be drawing a line from that gear button's pivot to some arbitrary position. I'm doing a ScreenToWorldPoint on the gear button's position and it's giving me that offset. It seems to be following a point a bit to the right of the button's pivot. What can I do to get the actual world space position of a UI element?

The canvas is a camera space overlay (of an overlay camera) and scales to screen size. I've tried eliminating the overlay camera from the equation by using it to get screen point to viewport, then viewport to world on the real camera. No dice, same offset.

[leaden ice]

You can use
https://docs.unity3d.com/ScriptReference/RectTransform.GetWorldCorners.html

[naive swallow]

This sort of works, but as I zoom out, the main camera's ortho size changes but the canvas is still in the same world location on the overlay camera, so the line doesn't move with it.

At the right size it does point to the spot I want, but not at any other zoom

[naive swallow]

Okay, I got it. I'm not proud of it, but I got it.

Vector3 pos0 = CameraSwapper.activeCamera.ViewportToWorldPoint(CameraSwapper.instance.uiCamera.WorldToViewportPoint(centerPoint));

I have to turn the world position into a viewport point on the overlay camera and use that viewport point on the main camera to turn it back into a world point

I am disgusted looking at this line and I hate myself but it works. Such is programming

[lean brook]

I'm trying to get specific pos X and pos Y values under rect transform. I used .anchoredPosition and .rect but didnt work

[leaden ice]

Put it in a helper function and never look at it again 😁

[river kelp]

Are there any good books that go a bit more in-depth into netcode for gameobjects architecture?

I was hoping for something that went a bit more in-depth about your options than the basic youtube videos I've found

Or, a book that taught you useful patterns for multiplayer games where you feel the knowledge is applicable to network for game objects would be cool too.

[steady moat]

Netcode for GameObjects have decent example and some conceptual knowledge. You could start there.
Otherwise, your option is to either look into youtube tutorial for Netcode for GameObjects, or too look for a book for multiplayer solution, not necessary with Netcode for GameObjects/Unity.

Photon: https://www.amazon.ca/Unity-Multiplayer-Games-Alan-Stagner-ebook/dp/B00HL2GOD2

[river kelp]

Thanks for the great reply. These books seem like they predate the netcode for game objects system, did you think they were useful in general when you read them? Like they taught you general good stuff?

[void basalt]

Multiplayer is generally all the same core concepts between network engines. It's usually just the APIs that are different. It all seems like good material to start off with

[steady moat]

As far as I know, Photon and Mirror are still actively maintained. You could totally do a full production on either of those.

why is the default cell swizzle for hexagon flat tops YXZ instead of XYZ? and why can't I get this to work? I have flat top assets, and I want a flat top grid with XYZ swizzling (ie, "no" swizzling).. but setting the swizzle of a hexagon flat top tilemap to XYZ rotates the tiles 90 degrees..

"flat top" hexagon with XYZ swizzling has the point on top

but point on top hexagon with XYZ swizzling ..... has the point on top

[somber nacelle]

this is a code channel

[modern creek]

Fine..

Why does

TileMap.SetTile(new(1,0,0), TileBase); 

of a hexagon flat top XYZ tilemap place the hexagon at 0,1 instead of 1,0?

[somber nacelle]

have you bothered reading the documentation?
https://docs.unity3d.com/2021.3/Documentation/Manual/Tilemap-Hexagonal.html

[modern creek]

Indeed.. and my question is.. for a Hexagonal Flat top tilemap - why is the default swizzle YXZ? the tile on top of the origin tile should be 0,1,0 - otherwise I have to mirror literally everything else in the Unity ecosystem to find the tile I care about - mouse position, world position, etc

Or in other words - How can I create a flat tile hexagon tilemap with XYZ swizzling - since my attempt at doing so yields this:

[somber nacelle]

why don't you go ask in #🖼️┃2d-tools where this question belongs? i'm sure the folks that hang out there might have more info about how the 2d tools, including tilemaps work.

[mystic ferry]

I'm using DrawLine to...well, draw lines in a grid system I'm working on, but the lines are extremely thin and even disappear at times when I move the camera. Is there a way to prevent this?

[dusk apex]

Gizmo or LineRenderer?

[mystic ferry]

gizmo

[dusk apex]

They shouldn't disappear if you're still drawing them Maybe provide code relative to the unwanted behavior.

[heady iris]

gizmos are editor-only

the lines are incredibly thin because they're intended exclusively for use as a visualization aid in the editor

[sleek bough]

you can turn on gizmo view in game window in editor, also make sure you've set time to display them, otherwise they will disappear instantly

[mystic ferry]

quite an eyesore but I guess if there's no alternative it is what it is

[mystic ferry]

code definitely isn't the issue and it's just a part of the engine, but here's the code nonetheless

public BuildGrid(int length, int height, float cellSize, Vector2 gridOffset = default(Vector2))
    {
        this._length = length;
        this._height = height;
        this._cellSize = cellSize;

        GameObject _parent = new GameObject("GridParent");

        _grid = new int[length, height];
        _textArray = new TextMesh[length, height];

        for (int x = 0; x < _grid.GetLength(0); x++)
        {
            for (int y = 0; y < _grid.GetLength(1); y++)
            {
                _textArray[x, y] = GridUtilities.CreateWorldText(_grid[x, y].ToString(), _parent.transform, GetWorldPosition(x, y) 
                    + new Vector2(cellSize, cellSize) * 0.5f + gridOffset, 10, Color.white, TextAnchor.MiddleCenter); //grid values
                
                Debug.DrawLine(GetWorldPosition(x, y) + gridOffset, GetWorldPosition(x, y + 1) + gridOffset, Color.white, 100); // bottom left upward
                Debug.DrawLine(GetWorldPosition(x, y) + gridOffset, GetWorldPosition(x + 1, y) + gridOffset, Color.white, 100); // bottom left rightward
            }
        }
        Debug.DrawLine(GetWorldPosition(0, height) + gridOffset, GetWorldPosition(length, height) + gridOffset, Color.white, 100); //top horizontal 
        Debug.DrawLine(GetWorldPosition(length, 0) + gridOffset, GetWorldPosition(length, height) + gridOffset, Color.white, 100); //right vertical
        ```

Looks like your game view might not be zoomed at 1x

But also, why does it matter, it's a debug line, it's not gonna end up in the final product

[mystic ferry]

I guess it doesn't but it's bothersome eitherway, I just figured I'd ask if there was a solution I missed

and it turns out I was right, I wasn't zoomed at 1x

I just like when my tools look pretty is that too much to ask 😔

How can I use enum on a button onclick function?

It works with SO, but not with enums.

I want to pass enum as an argument to the function.

[cosmic rain]

Enums are just ints, so you can pass an int corresponding to your enum value.

[upper pilot]

yeah but I have to remember what each int is.

[lean sail]

add it through code

something like

    void Start()
    {
        button.onClick.AddListener(() => TakesAnEnum(TestEnum.a));
    }

    public void TakesAnEnum(TestEnum someEnum) {}

Unless you're dynamically spawning buttons, this should be sufficient

[floral geyser]

I've had this issue twice in my project now, in two different scenes, and I can't figure out why it's happening:

When I disable, then enable a UI element during runtime, it becomes unclickable.

Does anybody have any clue why?

It's clickable before it's disabled

It seems to be that disabling it is what causes the problem, because if it starts disabled, then becomes active, then it is clickable

But if it is active, then is disabled, then becomes active again, then it's unclickable

[upper pilot]

Well, I just added a separate class that holds enum and I serialize it.
Then I just pass the class to the function so it can read the enum from it.

[lean sail]

sounds like an extra layer for no reason tbh, unless you REALLLY want to set this up in inspector

[cosmic rain]

You can troubleshoot it by looking at the event system inspector when hovering/clicking the button

[upper pilot]

It is for "Upgrade" buttons, but those are for different things.

I set them up manually.

In theory I could have an SO to store all possible upgrades, but that would still use enum or something similar since it upgrades different things such as Units/buildings/player

But it uses same UI.

[cosmic rain]

I never use the button component for global notifications or passing any kind of custom data. It should always invoke a method on a custom component on the same object that would take care of the actual logic.

[lean sail]

i generally prefer to setup buttons via some script, to keep them more in 1 place and because unity events are limited/hard to kinda go through your whole canvas to see whats linked.

[upper pilot]

yes I have UpgradeManager and the idea was to pass an enum so the manager could do the logic.

[lean sail]

U could just..
#archived-code-general message
instead of anything you described

[upper pilot]

don't you need to create all buttons through code then?

Or do you mean to get reference to all buttons and set listeners that way?

[lean sail]

U just get the reference and add a listener

[cosmic rain]

In this case the button would invoke a method in a "UpgradeElement" or something similar that actually has the required data.

[upper pilot]

yeah so what I need to do is when u click a button it doesnt upgrade anything, but update another UI with actual info.
That UI will have actual listener that "Upgrades" when you click another button.
So there is an extra step there.
Not sure if that matters tho.

[cosmic rain]

My position is that unity buttons should only handle the act of clicking it and not bear any additional context.

[upper pilot]

What do you mean by additional context?

[cosmic rain]

Like your enums

[upper pilot]

The button needs to have some sort of data right?

[cosmic rain]

No

[upper pilot]

Otherwise how is your script going to see the difference between buttons?

[cosmic rain]

It should only notify that something is clicked. No more, no less.

[upper pilot]

What is "something"?

[lean sail]

You can have 2 references..

[cosmic rain]

Because each button is linked to its own ui element that has it's own unique data.

[cosmic rain]

A button, a ui element.

[lean sail]

// assign upgrade 1 and upgrade 2 in inspector
    void Start()
    {
        upgrade1.onClick.AddListener(() => TakesAnEnum(TestEnum.a));
        upgrade2.onClick.AddListener(() => TakesAnEnum(TestEnum.b));
    }

    public void TakesAnEnum(TestEnum someEnum) {}

[upper pilot]

So the UI element is storing data? I am confused, what is the difference then?

Yes so the above is basically the same, but done via code

it is still storing data on a button, but you cant see it in the inspector.

[cosmic rain]

The difference is separation of concerns, single responsibility principle.
It makes it easier to debug, read and modify the code.

[upper pilot]

right

[lean sail]

no its not, its just adding to the delegate chain

[upper pilot]

So is it any different to having a regular onClick event on a button and adding a Scriptable Object as an argument?

Or does it have to be done via code?

[floral geyser]

It doesn't seem to be detected by raycasts anymore after being re-enabled, is what the event system seems to indicate. I have no idea why though, since the graphic raycasters are active

[upper pilot]

I know this was about enums, but in general is this bad practice to have any sort of arguments in onclick event on a button?(in the inspector)

[lean sail]

you could do it anyway you wanted. but in the version ive shown, its just referencing a button and adding a listener which is all done in 1 script. yours would involve making a unique SO for every different button

[cosmic rain]

It depends on your system design and preferences, but if you ask me, yes, it's bad.

[upper pilot]

Alright, I will see into it tomorrow when I get back to this.

I do feel like having any logic on my canvas is a pain to handle and I barely started with it 😄

[lean sail]

Idk if id call it bad practice, i just really felt so annoyed trying to go through my own code and seeing what each button was linked to when trying to redesign my canvas.
Id say its fine to setup some things in the inspector, like a pressure plate opening a door.

[upper pilot]

since I jump around between my script that handles logic and UI.

[cosmic rain]

Does it detect anything else in its place? Or nothing at all?

[floral geyser]

Nothing at all, I made sure to test without any other images or overlays, just the buttons themselves

[upper pilot]

Do you tend to have 1 Game manager that stores all SO data + make copies of it?
When I want to upgrade an Unit I have an UnitSO(asset file/not copy) which then I can use to compare in a List unitList.Get(unitSO).damage += 5
What would be a good way to handle this type of thing?
Do I just use SO as a way to identify an object, but only change data on a class/not SO(even if its a copy)?

[cosmic rain]

Then inspect the object in question. See if it has a graphic component and if it's linked to the button. Also that it accepts raycasts.

[void sundial]

I do implore you to check out the channel lol

[swift falcon]

how can i give a FPS character arms as a sort of viewmodel? i legit have no idea where to start with this haha

[cosmic rain]

I don't ever use ScriptableObjects as actual in game instances. I have separate plain classes that have a reference to an SO. SO are only for static data.

[misty drum]

how would i go about dispersing a various number of objects headed towards a single vector?

[swift falcon]

wdym dispersing

[misty drum]

so that they dotn stack like this

[swift falcon]

i am not sure i understand the problem. they are all heading to a single point and yes they will eventually converge

[misty drum]

ive tried a few ways and they all look uggo

ik, i want them to head to a general location, but the more head to the same spot, the less accurate they are to that exact point

[lean sail]

in general u should just have 1 something manager. Although I dont really understand what you're asking with this question.
I wouldnt change data on an SO at all

[upper pilot]

Right so if I want to "upgrade" an unit, my SO is storing base stats + List<Stats> which tells how much to upgrade per level(list count = max levels)
Then a class would copy those variables into its own set of same variables that can be used to upgrade units etc?

[swift falcon]

give them a target point

[cosmic rain]

If I understand you correctly, you should look at boids and flocking behavior.

[swift falcon]

then add a random amount to each target point

[misty drum]

boids?

[swift falcon]

so each one goes a slightly different location in the same general area

[upper pilot]

right I have 1 manager for different things, but never multiple managers for the same thing.

[swift falcon]

this is way above my pay grade and i have nothing to say about it

[cosmic rain]

The instance class doesn't need to copy the SO. It can reference it to use data defined in it.

[lean sail]

🤷‍♂️ could be some very weird niche case where you do have multiple. Which is why ill usually say in general

[mystic kiln]

How would i go about initialising a list, which stores an array of values which arent all the same datatype e.g. the list may look like this

[ [Vector2, Vector2, float, float] , [Vector2, Vector2, float, float] ]

[upper pilot]

Right, but I need to "upgrade" the unit, tho I can imagine that having a Getter that loops through a List<Stats> and counts the total might work too.

[soft shard]

You could use a List<object> but then youd have to know the order of your types and cast it to access the data, other options could be a Dictionary if you have unique keys, or a List<SomeClass> or List<ISomeInterface> where you could use a base class or interface for each type to derive from, or possibly ScriptableObjects though some (or possibly all) of these approaches might only make sense in specific cases, what exactly is your usecase where you need 1 list to hold multiple types?

[cosmic rain]

Yes, each time you upgrade, you can retrieve the relevant value and store the final result in your instance class.

[misty drum]

[System.Serialize]
public class ListTypes
{
    public Vector2 FirstVector;
    public Vector2 SecondVector;
    public float FirstFloat;
    public float SecondFloat;
}

public class ExampleClass : MonoBehavior
{
    public List<ListTypes> ListyMcListyList;
}

[mystic kiln]

So im working on a* pathfinding and for any given node that has been found (explored or not explored) i will need to store its [position, parentposition, fCost, hCost] so that when checking what nodes to explore I can get each nodes cost and then if i need the positions they are accessible. I explained kinda badly but i hope you understand that

[mystic kiln]

can you explain whats going on here im not super aware of object oriented and would like to understand this for future :D

[hushed notch]

You should define Node objects with the stats you want

Then it's just a List<CustomNode> etc

You probably understand Object Oriented more than you think, at least in this case with just properties and no methods, it's creating a custom object that has those properties and so you can reference them instead of having an unnamed array

[mystic kiln]

we are working with a lot of nodes at a time so we would only want to initialise the nodes we are using to save launchtime etc

[misty drum]

you create a class that stores specific variables. then when you make a list of thsi class, each list index can call all the variable sins aid class. so you could so something like

public List<ListTypes> ListyMcListyList;
public void Update()
{
  float x = ListyMcListyList(1).FirstFloat;
}

[hushed notch]

Don't see why you'd have to initialize nodes you're not using

[soft shard]

Ah I see, yeah, it would be good to have a specific class for the data you need rather than trying to make a generic one for any kind of data, Nyyssay's approach may be a better implementation for your usecase

[mystic kiln]

i might have misunderstood what you are saying

[mystic kiln]

right i see that makes sense

[mystic kiln]

ah okay nice

[misty drum]

youre makign a class into a pseudo "superVariable" that can contain any number of variable,s or even functions

[mystic kiln]

What does the [System.Serialize] do in this example? i know what [SerializeField] Does but am unsure with [System.Serialize]

[mystic kiln]

okay that seems logical

[misty drum]

its sort of the same thing for classes, im not an expert, someoen else cna explain better, but it allows the class using your variable class to actually see it, and in your inspector int he editor it allows you to intrerract with it

you can also put custom methods and stuff in there like its own class

[soft shard]

The attribute [System.Serializable] will let that class become serialized, so yes a bonus is it can be seen and drawn by the inspector (though only public types in that class the inspector supports, without editor scripting), and also means it can be saved by JSON or any other serialization method as well, its a good way to think about your data, most of the time, classes that use System.Serializable dont derive from anything, or derive from a class that doesnt derive from anything, so its good for pure data in most cases

[misty drum]

public class ListTypes
{
    public Vector2 FirstVector;
    public Vector2 SecondVector;
    public float FirstFloat;
    public float SecondFloat;

    public void FirstMethod()
    {
        FirstFloat = 69420f;
        Debug.Log(FirstFloat);
    }
}

public class ExampleClass : MonoBehavior
{
    public List<ListTypes> ListyMcListyList;
    public void Update()
    {
        ListyMcListyList(1).FirstMethod();
    }
}

basicly, youre making a list of a specific class, and that class is used as a glorified variable or method store-r

[mystic kiln]

right thats pretty cool

[misty drum]

that stored class cna do anythign a regular class can

[mystic kiln]

although any idea why its erroring?

[misty drum]

[System.Serializable]

use this

my bad

[mystic kiln]

oh okay thanks

[mystic kiln]

np :D

im not super good with c# i learned programming with lua...

[misty drum]

i leanred programming by understanding how google spreadsheet functions worked, so, to each their own

[hushed notch]

in terms of structure and general guidelines for first time devs; are there any major pitfalls to avoid? I've heard a lot about singleton's; what's the alternative? INstantiating certain things with constructors? Or does everything find its dependencies, etc?

[mystic kiln]

lol thats brilliant

[cosmic rain]

I really recommend going over C# basics. You're not gonna get far without knowing object oriented programming, since C# is object oriented language.

[night harness]

Theres a million different opinions on this but atleast from what I've seen a pretty common and reasonable middle ground is just having 1 singleton as a GameManager or such and grabbing and setting references using that if you need

[hushed notch]

Dealing with nodes is actually probably a really good way to start understanding Object Oriented Programming; can you think of some helpful things those nodes can do themselves, if you really needed to?

[misty drum]

dependign h=on how new you are, this is a good toe dip into programming

https://www.youtube.com/watch?v=tzq-DJeNIrU&t=11s&ab_channel=SpeedTutor

[cosmic rain]

Singletons are not bad, there's just good and bad use cases for them. The alternative would be getting references in some other way.

[hushed notch]

I'm intermediate; done a ton of Leetcode / Project Euler but haven' tmade a game, familiar with Python, javascript, Java, some C#

[floral geyser]

Figured out the problem, apparently on deactivation it was somehow getting pushed behind even the parent canvas in terms of sort order, I just used a sort order override and it's fine now, very weird

[night harness]

My GameManager has storied refs to all my other managers and such so just having my gamemanager as a singleton lets me get pretty much anything i need

[mystic kiln]

im not super new just mainly struggle with the concept sometimes, i wrote some scripts already for this project just havent properly dipped my toes into oop like this. I previously worked with some perlinnoise for generation.

[soft shard]

If you have a general understanding of C#, I would suggest "Infallible Code" on YouTube, to help you get familiar with code architecture and design patterns, (I also found "Medium" blogs good references for some patterns you can use in Unity) - singletons have their purpose and there are cases where there are better alternatives, but it largely comes down to why your using a certain thing, and that may be largely affected by the architecture you decide to use in your project

[misty drum]

theres no such thing really as a giant pitfall, cuz everything has its uses. the main thing is just try to make it so its easy to understand whats happening in your code, if you use 10 if statements in a row for example, youre gonna confuse yourself. and learn to use less repetative code when really necessary, if youre seing yourself make a script for each unit type that does 90% of the things the same, theres room to minimalize somewhere

[cosmic rain]

I mean C# is OOP. If you don't understand it, it's like you're using 5% of it's potential.

[misty drum]

prob the biggest annoying bug you will find yourself onc ein a while is making infinite loops with code, usually dealign with while statements and coroutines, when it happens your editor might crash and some stuf fmight not be saved, can be annoying

[hushed notch]

Yeah I figure the question was sort of "how long is a piece of string" in that it sort of depends

[mystic kiln]

yeah true, im working at it bit by bit ig but the questions i asked today definitely made me understand a lot more

[hushed notch]

I guess I'll try to make a game and figure out what went wrong after 😆

[cosmic rain]

We can't provide a comprehensive teaching course right in the discord, that's why you should look up rigid course or read the C# manual. Getting the knowledge by small pieces like you did now would only make you confused and add misunderstandings.

[misty drum]

its eaiser to give peopel tips than to tell them what to avoid tbh

[mystic kiln]

ill definitely take a look at these. Really enjoying c# so far though in comparison to python and lua it feels way more powerful

[soft shard]

I think thats actually a pretty good way to learn, if your more of a hands-on learner and learn better from experience, and not just reading/watching stuff and assuming its all accurate, I like to make "sandbox" projects to just isolate and test out ideas and game mechanics, AI, algorithms etc, and super small game-jam-sized projects to find where I ask myself "theres gotta be a better way to do this..." or where I get confused in my own logic, then I know what I likely should study (and usually make a "sandbox" for, to learn it)

[hushed notch]

Yeah i'm trying to return to some roots of a project I did in college in java; I had a 2D planetary gravity simulator that I could fly a ship around. Didn't even know Kerbal existed lol

But I like gravitational physics, I think I'm going to try to do some super mario galaxy esque space walking mechanics

[misty drum]

if you liek to learn vicariously, i would recommend finding youtube series where they show you how to make a specific small game, and follow allong with your own project doing the exact same thing, watching somethign vs doing the same thign while you watch it is exponentially more helpful long run

theres a whole onlien course series based on this idea if yourw willing to pay some money lol

https://www.gamedev.tv/

[soft shard]

One thing I found with watching videos, its a big help to actually NOT copy the code verbatim, and change things up, change the variable names, the values, maybe how you prefer to structure code (if they have everything in Update, maybe you like putting it all in different functions, if they use if-else, maybe you like switch-case, etc), I find you learn more and most importantly understand why they chose to write the words they did in the specific way they did, and see if there are other ways to do the exact same thing, then the question might become "why are there multiple ways? Which one is better? Whats the pros and cons of each? And is it a micro difference I should care about right now?", at least from my experience watching tutorials

[hushed notch]

I've just started instantiating ragdolls that I can drop into a big pile, so these are all good resources for when I get going, thanks

[mystic kiln]

sorry to keep asking questions but how would i add to this list using .add()

[misty drum]

depends ont he use case

[mystic kiln]

id need to make a new "ListType"

[hushed notch]

customlist.add(customobject)

[misty drum]

you could copy, or instantiate, or make a new one

[mystic kiln]

i mean like to make the object how do i set the values of it

so in my case

[misty drum]

list.add(new ListType);

[mystic kiln]

and to set the values of listType?

would i need to do that seperately?

[hushed notch]

lookup constructors and the basics of OOP

[misty drum]

list(ListType).value

[mystic kiln]

okay thanks :D

[misty drum]

list(ListType).Variable = x;

[hushed notch]

I'm not sure if you're asking about how to manipulate the List or how to manipulate your CustomNode

[mystic kiln]

I needed a constructor sorry for being a little wierd about it completely forgot about it. Definitely need more research into OOP

[soft shard]

If your looking for some resources, you could try searching "C# OOP tutorials" or even just "C# tutorials" and find a playlist you can follow along with, they should go over all the basics and hopefully more, other good resources could be W3Schools and MSDN for pure non Unity-specific C#

I have a big issue with my Text Mesh Pro text, basically it seems to not be working (completely invisible) when i build my game to Intel on Mac, but it does work when I build it to Intel+Silicon on Mac. Nothing in console is out of the ordinary, it can't load some dylib files but then it loads them later along the line. Additionally, some of the text appears to be unaffected.

[gray mural]

Hello, I have been struggling on it for quite a long now. How can it possibly be that SelectOption is printed twice when I click on the button? I call it like SelectOption(true) in Start method
void SaveCreateLevel
OptionSelectionField.cs

the strangest thing is that it's sometimes called once when I add a delay in start and call it in a few seconds

Ok, well, who knew that AddOptionSelectListeners(options) is called also in Start of OptionSelectField.cs. It adds a listener to all children, also adding it to the button that was created in Start method of another script. It is added multiple times when the gameObject with OptionSelectField script is set to active when I click on the button.

The most stupid issue,

[visual pollen]

Hey, was wondering if someone could point me in the right direction regarding something I am attempting to do. Such as a forum or key words to look up.

What I would like to do is generate a list of objects, eg OriginalList [1, 2, 3, 4, 5, 6, 7, 8, 9]

I then want to split this list up but not have any double ups, eg;
Player1 [1, 3, 4]
Player2 [2, 7, 9]
Player3 [5, 6, 8]

If anyone could help! That would be awesome, thanks!

[gray mural]

make a foreach through the list, then add a number to the random list if it is not full and doesn't contain this number already ?

[cosmic rain]

Just loop the list and add the desired elements to other new lists.

[visual pollen]

Appreciate the help! Will try do that and get cracking with it, thank you

I have a issue about modify meshInfo in the same frame in which TMP_Text is created. We can modify the meshInfo of the textInfo property of TextMeshPro’s TMP_Text to change properties like vertex colors of existing meshes. However, I’m currently facing an issue where if I place the creation of the TMP_Text and the code to modify the mesh within the same frame, the changes to the mesh get reverted. ```cs
Button button;
void Awake() {
button = GetComponent<Button>();
button.onClick.AddListener(CreateText);
}

void CreateText() {
    TMP_Text tmp = new GameObject("TMP_Text").AddComponent<TextMeshProUGUI>();
    tmp.transform.SetParent(FindObjectOfType<Canvas>().transform);
    tmp.SetText("This is a test sentence");

    tmp.ForceMeshUpdate();
    TMP_TextInfo textInfo = tmp.textInfo;
    TMP_MeshInfo[] meshInfos = tmp.textInfo.meshInfo;
    foreach (var info in meshInfos) {
        for (int index = 0; index < info.colors32.Length; index++) {
            info.colors32[index] = new Color32(255, 0, 0, 255);
        }
    }
    
    tmp.UpdateVertexData(TMP_VertexDataUpdateFlags.Colors32);
}```While debugging with breakpoints, I’ve confirmed that meshInfo.colors32 is indeed being modified. But as the execution continues, at some point, meshInfo.colors32 seems to revert back to its original state (the TextMeshPro codebase is quite extensive, and I don’t have the capacity to identify the exact issue). My only assumption is that there might be a refresh operation on meshInfo at the end of the frame after the creation of TMP_Text, causing the reset.

Is there any way I can prevent this reset from happening or, in other words, what approach should I take to immediately modify meshInfo in the same frame in which TMP_Text is created?

If I modify the mesh in the frame immediately following the creation of the TextMeshProUGUI component, it will not be reset. However, writing it this way is a bit cumbersome and is causing me some trouble.

[dense vessel]

I've tried your code and it works for me 🤔

(But by the way isn't there a color property?
Why don't you do tmp.color = Color.red ?
But both ways work for me.)

[neat herald]

Oh! I remember now, this is my fault. I had previously modified some code in TextMeshPro to reduce the occurrence of GC issues, but it seems I forgot about this. It looks like the problem was caused by my changes. Thank you for helping me verify this piece of code!

By the way, here I used modifying the color as an example, but modifying the meshInfo can achieve many impressive animation effects. However, for the sake of asking questions, I won't include such complex examples.

[cosmic ermine]

trying to do some marching squares, and for some reason my mesh just isn't rendering. Guessing I'm messing up my indices or vertices somehow. Is there a way I can debug view vertices or indices in a mesh?

[main shuttle]

Most of the time people forget to actually add the Mesh Renderer to their newly made mesh, so just to make sure, did you add one?

[cosmic ermine]

ye, definitely got one

[main shuttle]

Regarding the original question, I don't know. I probably would just DrawLine/DrawRay from your indices towards each other and see if they are what you think they are.
You could also put your Scene view in WireFrame mode and see if you did something wrong there probably.

[cosmic ermine]

Thanks!

Does someone know why the same listener is added 4 times here? The bool unique is set to true when method is called.

// private List<UnityAction> _listeners = new();

public void AddListener(UnityAction call, bool unique = false)
{
    if (!unique || !_listeners.Contains(call))
    {
        if (!_button)
            _button = GetComponent<Button>();

        _button.onClick.AddListener(call);
        _listeners.Add(call);
    }
}

private void AddOptionSelectListener(OptionSelectButton option, bool unique = false)
{
    option.AddListener(() => InvokeOptionSelect(option), unique);
    option.AddListener(() => InvokeOptionSelect(option), unique);
    option.AddListener(() => InvokeOptionSelect(option), unique);
    option.AddListener(() => InvokeOptionSelect(option), unique);
    option.SetActive(false);
}

those UnityActions have to be the same, but _listeners.Contains(call) is false

[cosmic rain]

Anonymous methods are all unique instances. They're not gonna be equal.

[gray mural]

any ideas what I should do instead?

[cosmic rain]

Pass in a normal method instead.

But it really feels like you're over engineering something.

[gray mural]

a normal method?

what does it mean?

[cosmic rain]

Not a lambda/anonymous method.

[gray mural]

I don't think it's possible..

[simple egret]

If these events are not meant to be linked from the Inspector, use pure C# events instead. Allows more control since you can specify the return type and arguments

[gray mural]

I will try, thank you both

[cosmic rain]

I mean, what you're doing is kind of redundant. You pass in the object to a method in the same object.

Ok, maybe not. But it still feels like you're doing something forcefully wrong.

Maybe explain what you're trying to do and we might provide a better solution?

[heady bronze]

Anyone able to explain what the frick is happening here? My child gameobject isn't remaining in the right position in relation to its parent.

[cosmic rain]

Some scaling must be involved.

[heady bronze]

Appreciate the response. I've checked every child game object and they all have a scale of 1,1,1 so I don't think that's it.... 😦

[heady bronze]

Seems like its caused by a Capsule Collider in one of the children... Weird, I'm not sure why that'd be.

[cosmic rain]

How do you know that?

[regal gyro]

I wanna make the bool to false when the raycast is not hitting an object with a tag "Chest" but it seems that when it hits one, it stays to true while the raycast is no longer hitting the object

if (Physics.Raycast(theRay, it RaycastHit hit, range))
{
       if (hit.collider.tag == "Chest)
{
       colHit = true;
}
else
{
       colHit = false;
}
}

oh god editing this in mobile is a pain in the ars

[dense vessel]

If the raycast is not hitting anything, the code inside the if() won't be executed so colHit will never be set to false as long as the raycast does not hit another object that doesn't have the "Chest" tag.
Is this the problem?
If so, you could add a else colHit = false; at the end 🙂

[regal gyro]

that's what I did though

[dense vessel]

No I mean like that :

if (Physics.Raycast(theRay, out RaycastHit hit, range))
{
  if (hit.collider.tag == "Chest")
  {
    colHit = true;
  }
  else
  {
    colHit = false;
  }
}
else colHit = false;

[regal gyro]

oh!

[spring flame]

I come back to unity after a long break and I got a bit rusty :P
How do I make a function that assigns variables to my component when I add a script to a game object or when it recompiles*?

[regal gyro]

nice thank you

[wicked cape]

how i can get which button clicked from list of button in unity through button.onclick event

[spring flame]

why do you need to check what button was it?

[brazen garden]

@wicked cape could u pass it through as an argument (Button this) from the button?

[wicked cape]

not working

its always print last variable

[fervent furnace]

maybe you can try

for(int i=0;xxx;xxx){
  int j=i;
  buttons[i].onXXX.adXXX(()=>Method(j));
}

[wicked cape]

i am using same

or what you want to say

[dusk apex]

So the lambda only caches the final result of the class variable

Make a new local variable and assign it the reference. Use that variable in the lambda instead

[simple egret]

It's important that the copy variable is declared inside the loop for it to work correctly

Else it'll be the exact same as i

[wicked cape]

okay

[wicked cape]

Thanks bro its working now

[fervent furnace]

idk why it works actually i d even know how c# compiler compile lambda experssion
(maybe it creates an object which stores the start address of il and the pointer to arguments)

[simple egret]

Yeah it does that! It creates a private class to capture the variables (they'll be fields of that class), and where the lambda is used, an instance of that class is created and the values piped into it

The body of the lambda is translated into a full method, stored in that same class so the captured variables as fields can be accessed

[fervent furnace]

thanks

Hi, I'm doing a project in Unity in which I need to record a video with the webcam, and I wanted to check if the webcam is available or is being used by some other application, does anyone know if there is a way to do it? I've been searching the internet and can't find any way. Thanks 🙂

[grim kiln]

I think this is the best you can do: https://docs.unity3d.com/ScriptReference/WebCamTexture-isPlaying.html

[rose basin]

I just tried it and it always gives me false, but the laptop's webcam works. I don't know why 😦

[unreal sonnet]

Hey guys how do you export the json files into the build of the game?

i have a saving system set up but it only works in the editor for some reason

[dense vessel]

Where do you save the json files?
It should work if you save them in Application.persistentDataPath 🙂

[unreal sonnet]

oh!

this is how my save path looks right now

do i just change it to Application.persistentDataPath + "/" + folder + "/" + fileName + ".json";

[simple egret]

Please use Path.Combine() to join paths!!!

[dense vessel]

Yes. dataPath points to the Assets folder but it doesn't work anymore in builds.
persistentDataPath points to a path that you can use to save stuff no matter the platform 🙂

[unreal sonnet]

thanks!

how do you see where persistentdatapath actually points to?

I have some singleton objects with event members. Other objects in the scene want to add and remove themselves from the event when they're enabled and disabled.

This causes errors when I stop the game. The singletons are getting destroyed before the other objects, so they're throwing errors when they try to use the singleton instance.

Two things here:

• I thought destruction only happened at the end of the frame. Do objects get destroyed instantly when a scene is unloading?
• Is there anything I can do to make these singletons die last, or do I just need to check if the instance is null before attempting to use it?

It's mostly a moot point because the scene is getting thrown out anyway, and failing to unregister doesn't have any consequences

it's not like this is a static event

[tired elk]

Well, objects are unloaded so yes, objects are destroyed at some point when unloading your scene

[heady iris]

I was just surprised by the ordering

if you destroy something in Update, the actual destruction only happens after the end of the update loop

but I guess it's different here

[tired elk]

I suppose it somewhat work like awake does

A specific function is called on every loaded object

But you have no guarantee of order

[heady iris]

right, and since the destruction appears to happen immediately, that becomes a problem

I could just make the event static.

[tired elk]

You could consider reverting the responsibility here

[heady iris]

it just feels weird to do that when everything else about the singletons are non-static

[tired elk]

And make your singleton release all of its listeners in OnDestroy/OnDisable

OR

[heady iris]

The individual listeners will be getting destroyed throughout a gameplay session.

[tired elk]

Unsub your listeners in OnDisable, which should be called before the singleton is destroyed

[heady iris]

nope, OnDisable and OnDestroy go off on the singleton before the listener's OnDisable is getting called

(destroying an enabled monobehaviour runs OnDisable and OnDestroy in sequence)

[tired elk]

Yeah, but I thought it could be different when unloading xD

[heady iris]

i checked with some log messages

[tired elk]

IIRC, if it's not a static event, the subscription lives with the object that holds the event. So you could simply check if the instance is null.

If instance is not null, manually unsubscribe. If it is, it should be handled automatically.

[heady iris]

Right, that's what I'll do

I was just hoping I could avoid having to check if the singleton is valid every time

[late lion]

You could make a static wrapper of the event, that checks if the instance is destroyed:

private Action _myEvent;

public static event Action MyEvent
{
    add
    {
        if (Instance == null) return;
        _myEvent += value;
    }
    remove
    {
        if (Instance == null) return;
        _myEvent -= value;
    }
}

Or doesn't need to be static necessarily

[heady iris]

also, huh, I'm a little surprised by the error I'm getting

I was expecting to be told the object was destroyed

not that it's null

oh, right: my singleton class is trying to find the object in the scene

[tired elk]

If the purpose is to have the null instance be checked, it needs to be static

[heady iris]

using UnityEngine;

public abstract class Singleton<T> : MonoBehaviour where T : Singleton<T>
{
    private static T _instance;
    public static T Instance 
    {
        get
        {
            if (_instance == null)
            {
                _instance = FindAnyObjectByType<T>();
            }

            return _instance;
        }
    }
}

so it's calling FindAnyObjectByType<T>() again and failing

I still thought that returned a "dummy object" that threw errors when you tried to use it

i swear GetComponent did that for sure, but neither is doing that

[late lion]

Only if the instance is truly null. If it's just destroyed, you should still be able to use non-Unity properties and fields on the instance.

[heady iris]

That's what's confusing me -- calling GetHashCode() or accessing any non-unity member throws the NRE

[late lion]

Isn't it because you're overwriting the destroyed instance with null in the Instance getter?

[heady iris]

yeah, but I figured FindAnyObjectByType would do this

[tired elk]

Yes but in typical Singleton pattern, don't you set instance back to null in OnDisable or OnDestroy ?

[heady iris]

also, I threw this into the if (_instance == null) block:

_instance?.What();

where What() just logs "WHAT?" to the console

it never runs

this implies that I never attempt to read the Instance property whilst _instance isn't literally null

oh

nvm that was because other code I wrote was throwing an exception before I could try to read it, haha

okay, yes, there is some instant where it's a destroyed object, not literally null

and then FindAnyObjectByType literally returns null

okay, so one idea here:

if the FindAnyObjectByType fails, don't do anything

everyone else can then happily unregister their events from the singleton's dead body 😬

This could cause problems if I load a scene containing objects that want to use that singleton that doesn't exist in that scene

however, I would simply not make mistakes

🙂

Works like a charm. I will be judged for my sins.

[obtuse hemlock]

hello, is there anyone here who could help me to generate a txt file with Windows (CRLF) and UTF-16 LE. I only managed to get UTF-16 LE working, but when it comes to the first requirement, my file keeps getting out as Macintosh (CR) for some reason.

This is my current code - https://sourceb.in/KkK8kDSZ3J

[heady iris]

silly thought, but what happens if you do "\r\n\n"

[rocky helm]

Holy mother of jesus what is a 'tuple literal expression'?

rigidbodyChanges.Add(new (Rigidbody, Vector3, Quaternion)(rb, relativeTo.position, relativeTo.rotation));
error CS8181: 'new' cannot be used with tuple type. Use a tuple literal expression instead.

rigidbodyChanges.Add((Rigidbody, Vector3, Quaternion)(rb, relativeTo.position, relativeTo.rotation));
error CS0119: 'Rigidbody' is a type, which is not valid in the given context

rigidbodyChanges.Add(new (Rigidbody rigidbody, Vector3 position, Quaternion rotation)(rb, relativeTo.position, relativeTo.rotation));
error CS8181: 'new' cannot be used with tuple type. Use a tuple literal expression instead

rigidbodyChanges.Add((Rigidbody rigidbody, Vector3 position, Quaternion rotation)(rb, relativeTo.position, relativeTo.rotation));
error CS8185: A declaration is not allowed in this context.

[tired elk]

(Rigidbody, Vector3, Quaternion) is a tuple

And you're trying to do new (Rigibody, Vector3, Quaternion)

[rocky helm]

What about this one rigidbodyChanges.Add((Rigidbody, Vector3, Quaternion)(rb, relativeTo.position, relativeTo.rotation));

[tired elk]

Again, a tuple

[rocky helm]

I want a tuple

[tired elk]

I'm not even sure of what you're trying to do with this syntax

[late lion]

You don't need to specify the types beforehand:

rigidbodyChanges.Add((rb, relativeTo.position, relativeTo.rotation));

[rocky helm]

I want to add a tuple to a list

[rocky helm]

yes thank you

[hushed notch]

A tuple is anything in parentheses

It's like an array but less flexible

typically it can be hashed and is not mutable, unlike an array

Useful because you can use a tuple as a key, or as part of a set, unlike a regular array

[rocky helm]

I know, I just didn't understand what unity was screaming to me about

[rain minnow]

it was your syntax. when you had the types beforehand it thought you incorrectly typed a tuple literal, where you supply a name to each item instead of using Item1, Item2, etc. . . .

[static matrix]

I presume using a script such as this:

void Update()
    {
        if(Vector3.Distance(transform.position, Player.transform.position) >= 60)
        {
            GetComponent<MeshRenderer>().enabled = false;
        }
        else
        {
            GetComponent<MeshRenderer>().enabled = true;
        }
    }

(lots of objects using this)
will save perf more than not using it
like the lag caused by this script will be less than the lag of rendering

[knotty sun]

Dont want to be doing GetComponent in Update if you can help it

[static matrix]

good idea

I need to break the habit of using get so much
ive gotten a lot better at not using Find in update

[knotty sun]

GetComponent is fine in Start just not in Update

[static matrix]

yes exactly
im incrediably stupid I had even already got meshrenderer for a different part of the script

[knotty sun]

but yes, disabling the renderer when not in use is a good idea

[static matrix]

ok cool

[lean sail]

Seems like u also dont need the actual distance there. You can take the square magnitude and compare that to the 60 squared instead

[static matrix]

this will be more helpful than clipping planes bcause sometimes I need to render far geometry for immersion
but a lot of the far geometry in this area is covered so I can de-render some of it

[static matrix]

huh? im not sure I understand

[knotty sun]

when you use Distance you are using a square root. this is a heavy math function. using square magniture (in your case 60*60) is more efficient

[lean sail]

https://docs.unity3d.com/ScriptReference/Vector3.Distance.html
The formula uses magnitude. Magnitude uses a sqr root, which you can avoid in this case

[deep path]

yoo
does it make sense to use Symbolic Link at cmd
just to change the Cache directory from drive C to D ?

[static matrix]

so how would I fix this, do I still use vector.dist or something else

[knotty sun]

If you really, really know what you are doing with symbolic links then, yes

[hoary dune]

After an update to Authentication package, to login with steam it is suggested to use identity, however it lacks clear explanation what identity actually is, is it a unique game id? player id? Is it something I should retrieve as a part of steam login process?
https://docs.unity.com/ugs/manual/authentication/manual/platform-signin-steam

[knotty sun]

subtract the 2 vector3's then test the result.sqrMagnitude

[static matrix]

oh duh I can just dubtract

[swift falcon]

hey can anyone tell me how i can make it so it looks forward instead of right
https://hatebin.com/fcusqfdcpn

[static matrix]

is this in 2d?

because if its in 2d and you made the sprite you might have to rotate the sprite in whatever you made the sprite in

[obtuse hemlock]

well, let's try, it's probably something silly indeed

[static matrix]

to try and optimize more, imma add a script that gives objects rigidbodies only when they collide
so they arent eating up process power

[obtuse hemlock]

nope, same result, but it added 2 line breaks instead of 1

[heady iris]

so it's outputting two carriage returns?

[obtuse hemlock]

if it helps, asked in another channel about plain c# and the guy said my code works outside unity

he said it can be something with the compiler

[heady iris]

how are you checking the result?

[rocky helm]

I would just make the rigidbodies on the objects kinematic and make them not kinematic once collided with, instead of adding the rigidbody component once collided with

[static matrix]

thats.... a very good idea

[obtuse hemlock]

like this, plus this file represents a DB table, which I need to import using another app, my generated file returns a error, so I start to investigate and this format thing was the only difference I could find

[heady iris]

i'm not sure i'd trust Notepad's interpretation

can you send an example of a broken file?

[obtuse hemlock]

I believe so, this was the output with your suggestion, with the original code the result was one line break per line

[obtuse hemlock]

sure, I can send you both actually, the reference and the broken one

wait a sec

may I send you a dm with it? or I can add it here?

[heady iris]

you can just drop it in here if it doesn't have anything sensitive in it

[obtuse hemlock]

no, it doesn't

wait a sec and thanks for your help

I'll remove your suggestion, I'll add one generated with my original code...

here it's

they're big

[heady iris]

I wonder if it's actually turning "\n" into "\r\n"

[static matrix]

is /r remove in regex?

[obtuse hemlock]

if this was for me, I don't know...

[static matrix]

yeah it was for you

[obtuse hemlock]

first time generating txt stuff with specific requirements

[static matrix]

bcause /n is line break and obviously you dont want "\n" everywhere so it might be trying to remove it but something is going wrong somewhere?

just a wild guess

[heady iris]

Yeah, it is.

Your bad files contain the following hex sequences at the end of each line

0D 00 0D 00 0A 00

UTF-16 encoded \r\r\n

Your good files contain 0D 00 0A 00

that's \r\n

I wonder if using '\n' -- the character -- will make it behave differently

[heady iris]

I know that Python does this.

[obtuse hemlock]

use only "/n"? well, I'll try

[heady iris]

no, specifically writing '\n' instead of "\n"

'a' is a single character

however, you can also just try joining with "\n"

since that appears to be becoming "\r\n"

[heady iris]

the idea being that it can't possibly expand that into "\r\n" because it's a single character

but I don't know where this magic change is happening...

[obtuse hemlock]

ok, I'll test it again

[heady iris]

oh, you know

this might also just be because a \r got left behind by the splitting

[obtuse hemlock]

my man, you're awesome hahah

it worked

[heady iris]

That sounds more plausible to me.

So the last entry would be something like

5000\r

then you add \r\n at the end and get \r\r\n

[obtuse hemlock]

you think only the last entry has the additional \r which made the format wrong?

only a curiosity anyway

[heady iris]

well yeah, because that's where the \r lives

at the end of the line

[obtuse hemlock]

hmm

[heady iris]

try doing .Trim() before splitting each line

[obtuse hemlock]

got it

nah, I prefer to stick with this functional version lol

unless you really wanna know this, in this case, it's least I can do considering your help

[bleak thorn]

Hi I have problem with destroying obstacles on retry button.
In editor everything is okay, but on mobile phone script doesn't works properly (second video) why?

[knotty sun]

use Android LogCat

[gray mural]

I am adding a listener to every OptionSelectButton.cs in OptionSelectionField.cs. But the same listener is added multiple times, that leads to an unpleasant behaviour

[broken light]

any one know why in my editor script i keep losing the reference to the object field when i lose focus on the gameobject

[gray mural]

noone knows how do you get the reference?

[broken light]

in my editor script i have:

        [SerializeField]
        GameObject _prefab;

with this line of code in my OnInspectorGUI()

_prefab = EditorGUILayout.ObjectField(_prefab, typeof(GameObject), false) as GameObject;

[gray mural]

actually I have moved multiple listener add to all gameObjects in from Start to Awake, well, everything works now.

[gray mural]

what if you move this to OnGUI() method?

[steady moat]

You need to apply the change. Also, you should use property field if possible to have prefab support.

https://docs.unity3d.com/Manual/editor-CustomEditors.html

[broken light]

their example is using properties from the monobehaviour though

this particular reference is only in the editor script

[steady moat]

Where you keep your data ?

[broken light]

in the editor script

[steady moat]

Then when are you losing data ?

[broken light]

when i lose focus on the object in question

if i then click back to it the fields are blank

[steady moat]

Yes, because your editor is closed.

It lives only when you inspect it.

[broken light]

ah i see

so i would have to put it in the monobehaviour for it to stay alive

[steady moat]

Exactly

[broken light]

thats frustrating

[steady moat]

Not really

[broken light]

since its editor tool only not scene objects

[steady moat]

There is other option

[steady moat]

EditorWindow

[broken light]

i see, i'll look into it

i read about it but didnt opt to use it

[gray mural]

you can also use SerializedObject

[broken light]

i guess i could use a SO

ill try both see which one makes more sense

[steady moat]

If you want your information to persist through multiple session you would need a Scriptable Object

#archived-code-general message

[gray mural]

Is there a method that is called when a field is changed in the script? Like OnValidate, but it is called when a field is changed in the inspector

or do I have to use custom properties and/or methods?

I see, I'ma just call the method after assigning fields I need

[light rock]

thats exactly what onvalidate does

[proven epoch]

Hi! I have worked with unity for a while but I am not an expert by any means.

How do you guys go about writing scripts and building tools for your game development that you can then use accross multiple projects (so you don't have to keep reinventing the wheel or copy paste code from other projects?)

[light rock]

wait, are you asking for the thing that does it when it changes in the inspector? or when it changes through script? if through script, then use properties

c# properties, to be specific

if in the inspector, use OnValidate

[gray mural]

Is there a method that is called when a field is changed in the script?

[gray mural]

yeah, I have also been talking about it

it's just very uncomfortable.

making a property for every field..

[light rock]

you can use auto-propeties

public int x {get; set;}

and only implement the set; function

[gray mural]

I see, yes, it makes sense, but you can't serialize it directly in Unity

[light rock]

i think theres a way. hang on

[gray mural]

yes, there is

by making generic class

[light rock]

well, anyway those are the ways that you can do it. in c# a property is basically a field with a way to run code whenever it changes
