this isn't a code problem

[simple ridge]

Im writing this tool for the use of non-technical people. So I'd rather get these sort of things done automatically

This is for use as a university experiment, so the students who will be using this won't have a background in game dev or understand how the unity editor deals with docking windows.

I agree this seems like a silly thing to need to do, but for me its worth getting rid of as many potential issues as possible with this sort of thing

If its not possible then I know you can save and write specific layouts through code so I will do it that way, but just wanted to make sure I wasn't missing something in terms of accessing tab data from an already existing window.

[steady oasis]

how can i prevent this from happening?

basically i kept my gun too close to the camera and now it cuts itself and shows its inside.
pls ping me if u have an answer because i am going for lunch and will be seeing the replies after i come.

thanks,
MrcJoc

also idk where to post this problem i post in genrel

[leaden ice]

• move it away
• modify the near clipping plane of your camera

It should go in #💻┃unity-talk

This is NOT a coding question

[simple ridge]

@leaden ice do you know if this remotely possible through script? if not then I will just do the other approach but I do mean this as a code based question for custom editor scripting.

[leaden ice]

Look at the last overload at the bottom https://docs.unity3d.com/ScriptReference/EditorWindow.GetWindow.html

Also #↕️┃editor-extensions

[simple ridge]

Ah thanks, I had a look at this class for implementation but didn't see the list for desiredDockNextTo.

And yes, sorry I didn't realise there was a channel specific to editor extensions.

Ill use that in the future! Thanks ^-^

I have conflict in the interface , I can't make an alias for each library so how to resolve it ?

error CS0433: The type 'IAsyncEnumerable<T>' exists in both 'Microsoft.Bcl.AsyncInterfaces, Version=8.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' and 'netstandard, Version=2.1.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'

[cold parrot]

Use the full name (including namespace) when referring to either one in the same script

[tired apex]

how syntaxally

[gray mural]

Microsoft.Bcl.AsyncInterfaces.IAsyncEnumerable

[tired apex]

before the interface ?

[gray mural]

Use it when referring to it

Or remove one of the namespaces you don't need

[tired apex]

I can't remove it ( Its needed for other snipppets )

[gray mural]

Right, then refer to it including the namespace

[tired apex]

supprise

[gray mural]

Are you sure you have installed the Nuget package?

[tired apex]

locally yes

[gray mural]

Well, you cannot use it, so you haven't

[tired apex]

also Nuget package manger acting weird !

[tired apex]

I did in unity , other script use it without any problem

[gray mural]

You have done it in Unity? Nuget packages may be troublesome there

Are you suge you have placed the dll correctly?

[tired apex]

yes

[gray mural]

Well, it doesn't work, so, probably, no

[tired apex]

as it cause conflicts I need to build custom dll library which cast it to the correct namespace -alias

[gray mural]

Have you gone thru this post on Stack Overflow?

[tired apex]

I extract all nuget manually because Nuget for unity cloudn't decide which version so I extract all nuget-s that target 2.1 api {and all its decencies } and it seems work just fine in unity

[gray mural]

But it doesn't work in your code though

[wintry gust]

The issue is this is for an individual audio source. Meaning I'd have to go around multiple points in my code and stop each individual audio source. I was hoping for a way to stop all audio sources globally.

[gray mural]

Either store them in a List or use FindObjectsOfType<T>

[indigo orchid]

hello I want to make an attack I have 2 meshes for it and want to do it such that when Q is pressed the attack mesh is switched to from the standing mesh pls help

[knotty sun]

#💻┃code-beginner and

[swift falcon]

I have some problem... So generally I know how to communicate the scipts, get the components bla bla. but the real is issue is that I'm not able to create a system that works properly and effectively. So I learned that I should check it out the scriptable object lesson in unity but also I'm curious is there something that u should suggest me to learn before this subject?

[oblique spoke]

What issues are you seeing with the way you are currently doing things?

[leaden ice]

What kind of "system" are you looking to build

Seems really vague

I'd make sure you really have mastered references and prefabs and lists and things first

[indigo orchid]

Thank you very much

[swift falcon]

I want the object interact each other but when i do it with only prefabs its really a lot work to handle all things. So I know need something like scriptable objects system. But also i asked if there a more system like that i should know. So also I’ll take a look at that too

[thin hollow]

[requirecomponent ()] attribute forcefully adds the specified component to the game obgect if it is not present. Is it possible to instead make it so that you can't add this script to the game object if the required component is missing, and not create it automatically? I want the script in question only be able to be added to specific object types, not turn any object into object type the script is intended to be used with.
IIRC some native Unity script don't allow to add itself to object with missing component, so I want to replicate that behavior.

[remote scarab]

I changed the execution order for a script in order to make it init before others however after doing so now the project always stalls on start. The editor freezes and doesn't allow any input through the ui or even the close/minimise/restore/maximise buttons or moving the window itself. Unity's RAM usage keeps going up until it maxes out around 80-90% (making my total ram usage about 90-100%). Then just sits there and can only be closed through task manager.

I've tried reverting the execution order changes, changing the order to something else, updating Unity Hub, and restarting my computer. Other projects seem to run just fine, it's just this one. I've attached the current execution order (underlined one is the one that I have tried removing and is the one I added in). The execution order UI seems a bit bugged (or just isn't working how I expect) as sometimes when I hit apply it'll revert or change the order before applying.

Apologies if this is the wrong place to ask, I'm unsure where to ;-v-

[fervent furnace]

dead loop in your script

changing execution order solves nothing, you need to figure it out

[remote scarab]

changing execution order was to solve a different issue, I'll check any loops that this fix would make accessed now.

yeah, it seems to have been a faulty while loop. my bad there, thank you @fervent furnace

[static matrix]

erm
what is this
why is it doing this

[serene bolt]

Hello,
I have a problem with the Time.deltaTime.
I have a project which is a board game inside unity and i need to be able to clear the board when starting a new game. I'm using the Time.deltaTime to move the pawns and animate the movement and its working perfectly.
But once i've cleared the board (by deleting all childs and making it back, with the same functions i use when creating it), the Time.deltaTime used in the animations does not grow anymore 🤔
I have no idea where it can be broken so pls help me 🤣

Screenshots :
1 - the code to move the pawn, its called in a subroutine
2 - the subroutine call
3 - console output when its working (before clearing the board)
4 - console output when its broken (the deltatime is not increasing anymore 🤔 )

[mellow sigil]

I'm guessing at some point you set timeScale to zero

[knotty sun]

looks like you set timescale to zero and forgot to set it back to 1

[serene bolt]

oh, its a group project and i never heard of that 💀

looks like i'm gonna ask some questions to my teamates 👀

thx i'll check that

i don't know where it was set to 0, but i just put it back to 1 when creating the board and its working 👀

if something else is broken in the code i will think about it later 🤣

Thank you very much 🫶

[mental rover]

it would be a good time to learn a bit about your IDE, you should be able to do a search across the codebase for uses of Time.timeScale

find where it's been used and why

[serene bolt]

yes good idea

i found it and i know who i need to kill 👀 😈
(i'm joking i'm not gonna beat my friends)

[light surge]

Hello there. If I have a code that place, move and create a ton of object (World creation). What is the best way to reduce the waiting time and enable the loading bar to move (not 25s between frames). Jobs system, System.Threading or Inumerator?

[fervent furnace]

https://discord.com/channels/489222168727519232/1062393052863414313 is your only choices probably, you cant multithread instantiate

[fast dune]

How can I unzip a .zip file?

[light surge]

What do you mean?

[fast dune]

within a script, how can i unzip a .zip into a directory

[light surge]

oh, ok. More clear now.

[leaden ice]

Find a C# zip library. Pretty sure there's one in .NET probably

[light surge]

Dots, I have heard about it. Do I need to modify the code heavily if I just need to place a lot of object and no dynamic interaction?

[light surge]

That's a question for dots rooms. sry

[leaden ice]

Spread out instantiation over multiple frames

In a Coroutine for example

[light surge]

I see, I will use a Coroutine for instanciation and a jobsystem for other script.

[rocky jackal]

why can this code detect if theres no , but it cant replace it

[fervent furnace]

string is immutable

so any method does nothing on the orignal string, they return you a new string

[cursive kestrel]

hello, anyone knows how to make a circular button ?
when i use a round sprite, you can still click it as if it was a rectangle

[rocky jackal]

thank you

[daring plover]

hey
i have this VERY nested list with lists and stuff inside... how can i get to Currency Code and Currency Price by item name and category name?

my brain is fried

[wintry crescent]

I think I'm gonna blow your mind - learn about Scriptable Objects, I think they're perfect for your usecase
And dictionaries, too

[waxen blade]

I have a scriptable object that is unable to use the GetComponent method because it requires monobehaviour, but my object is currently inheriting Scriptable Object, so I can't add it on. I have another script inheriting this object as well.

I'm guessing I could create yet another class that inherits monobehaviour for yet another layer of monobehaviour, but is there a better approach to being able to utilize GetComponent?

[daring plover]

And dictionaries, too
cant realy serialize dictionary and dont wana use adons to

but i forgor about scriptatbel obejcts so ty for remining

[wintry crescent]

you can serialize lists, and create a dictionary from the serialized list, dynamically at runtime - and reference the dictionary when coding!
Unless you really need the dictionary in edit mode

have a list for editing stuff in editor, and a runtime-only dictionary for referencing it from code

[daring plover]

also blow my mind failed

this data is remote

afair s.o. is local

sory if me stupido its 12 am

[wintry crescent]

you can't do component from a scriptable object, because a scriptable object is just a random file effectively, not attached to a gameobject
you can go gameObjectVariable.GetComponent from within some function that's on a scriptable object, or you can just run what you need on a monobehaviour and just pull data from scriptable objects

[daring plover]

i get it froma server

[wintry crescent]

you could use addressables to pull the SOs from the server as well, perhaps

[daring plover]

ok by serevr i mean plafyab

[daring plover]

hwo do i dio this tho

[wintry crescent]

you either loop through the nested lists every time you want to access an element, and compare the data in the list (like name) with the data you wanna grab
or you create a dictionary at runtime, using the data from the list

[waxen blade]

I just found that I can do this:

GameObject.FindGameObjectWithTag("Foo").GetComponent<Bar>();

This works fine for my purposes. Thank you.

[wintry crescent]

FindGameObjectWithTag is pretty slow. Doing it once is fine, doing it a couple of times every frame will slow things down. If you can, I'd pass the gameObject Foo into your function on the ScriptableObject as a parameter instead

[waxen blade]

I'm surprised to hear that. I have always been told to avoid finding GameObjects by names and to only use tags since it's a lot faster, but I didn't know that searching by tag was also slow.

[wintry crescent]

it's definitely faster than finding it by name, yes
but it's not particularly... fast
and also hope you don't have multiple objects with that tag, too

it's best to just pass it as a reference, really

[waxen blade]

I only associate one object per tag, and it's also not being ran in an update method. But in that case I'll try to avoid using that when I can.

[wintry crescent]

preformance wise it'd be fine then, but I think it's good practice to pass it as a parameter instead
or optionally, consider making it a singleton - that's much faster, and also it's a cool pattern, I'm using it all the time

[spring creek]

This is a guide a friend made

What you're doing is equivalent to C tier.

[gilded sapphire]

Hey everyone, how can i use the object the raycast had a collision with (interactable) in a future update cycle to disable a component of that object? I have tried a lot of different things, but nothing seems to work

[spring creek]

Store it in a class member variable

[brazen totem]

i am trying to make my enemy shoot in a parabola curve , someone knows how?

nothing on google...

[vagrant blade]

Copied your question word for word.

[gilded sapphire]

interactable is already a class variable though, i think

[spring creek]

Not in that script

[gilded sapphire]

Ok thanks, i will search around a some more

[spring creek]

What do you need to search around for? Just make the variable in the class (not in a method) and assign it in the raycast condition body

[gilded sapphire]

It works, but the outline isnt cooperating, just have to fiddle some more. Thanks for the help

[clever harbor]

Does anyone know if its possible to set the cursor to the hand? Like the default OS cursor when you hover over a button

Without manually setting my own cursor icon of course

[rigid island]

No you need the cursor texture

[late lion]

You need to use native libraries for the operating systems you intend to support. For Windows, you would need to P/Invoke the SetCursor function in user32.dll.

[light surge]

Thank you, it works perfectly now.

[dim latch]

How can i get the object size of a probuilder mesh filter? i notice there's a read only property in the editor which would be super useful info in a script but i'm not sure the property name or how to access it, the tooltip or any buzzwords don't show up in a search on the ProBuilderMesh script

This is the property for reference

[mossy snow]

that code's in a custom editor (ProBuilderMeshEditor). It's merely reading mesh renderer bounds.size

[dim latch]

Ah, i already tried that but all the properties were just 0. I was getting the mesh renderer of a prefab, but i tried it again with the prefab instantiated this time and that seems to work fine

[old sigil]

anyone here any good with splatmaps i got a question?

im trying to get my terrain to update in the size of a collider. basically my player stands in the collider hits f and the terrain in the collider should be updated with a new texture. I've been debugging and i can tell its going through the function in its whole and im grabbing the correct layer in my terrain textures but it's not updating the terrain.

its just a flat terrain for a 2.5D game so nothing crazy is going on with the terrain at all i just dont know what im really looking at lol

Thank you! https://hastebin.com/share/agiwameviq.java

I do know that it passes in the correct collider

[knotty sun]

where do you define your splatPrototypes

[old sigil]

They are in the terrain layers of my terrain component

so index 0 is grass index 1 is soil

[knotty sun]

if you are changing texture should this

splatmapData[0, 0, 1] = 1f; 

not be

splatmapData[0, 0, 0] = 0f; 
splatmapData[0, 0, 1] = 1f; 

also you only appear to be changing the texture for one single point

[old sigil]

like one pixel?

[knotty sun]

yes

[old sigil]

you are absolutely correct i just saw that

[knotty sun]

this

float[,,] splatmapData = terrainData.GetAlphamaps(mapX, mapY, 1, 1);

get one point of width and height at the specified position

[old sigil]

i see now, apologies this is like week 1 of ever touching a game engine lol any ideas on how i could expand that to cover the amount of terrain a collider is covering?

[knotty sun]

drop the code in for loop to cover the area of the collider, not the most efficient way but the easiest

[old sigil]

thank you very much for the help i've been on the struggle bus with this for a while! terrain has been a very daunting aspect for me when it comes to scripting it.

[winter frost]

currently having issues figuring out how to preserve some player data when transitioning between scenes - is it common practice to store player data in some singleton game manager rather then the player, or call DontDestroyOnLoad on the player and just move them/disable them when transitioning to scenes?

[upper pilot]

Hey, Input Controller gives me a Verctor2 for 8dir movement which can be: [1, 1] or [1, -1] or [0.67, 067](for diagonal) etc.
Is there a way to clamp Randomly generated values to fit the above?
What systems people use? I want to have Npc walk in a random direction without having to type clamp(value, 067, 1); or something similar.

do I convert angle to direction instead and move npc in a random angle?

Vector2 direction = Quaternion.AngleAxis(angle, Vector3.forward) * Vector3.right;

I can get random angle by getting random number 0-7 and multiply by 45

[late lion]

Are you sure diagonal is 0.67? A 45° diagonal vector of length 1 is 0.707, 0.707

[upper pilot]

That was an estimate, but ye

[late lion]

You can calculate a point on a circle with a random angle:

var randomAngle = Random.Range(0f, Mathf.PI * 2);
var pointOnCircle = new Vector2(Mathf.Sin(randomAngle), Mathf.Cos(randomAngle));

Sorry, I missed that it's limited to 8 directions.

[upper pilot]

Yeah I am testing above code, for some reason it doesnt work exactly the same as player movement.

But its close

[upper pilot]

I mean this

[late lion]

With 8 limited directions, I would just pre-calculate the directions into a lookup table/array.

[knotty sun]

why not just calculate the 8 direction vectors you want and hold them in an array, then randomly select one of the entries in the array?

[upper pilot]

Even if player movement uses input system for its direction?

[knotty sun]

sure

[upper pilot]

Alright, I guess that sounds like a plan then haha, I will give it a go

ok I see the issue with my code

x = 5.960464E-08
y = 0.9999999

Guess I will just make a dictionary of vectors so I can use Enum for a direction too in case I want to create a path for npc later.

[reef creek]

Hello everyone, I'm having an issue with Unity: I'm creating a card game and working on a deck from which players can draw their cards. However, every time I actually draw a card, this error appears in my console, and since it doesn't give me much information, I really don't know where to go. My code doesn't have any string of the TYPE type, and when I checked my code, everything seemed to be working fine.

I know I didnt show any parts of my code, but it is because I dont know if this is the exactly place to put it or if I should create a post

[leaden ice]

For the love of god open your console window

Read the full error message

And the stack trace

[reef creek]

Its because theres nothing specific there, the error message is simply:

type is not a supported string value
UnityEditor.RetainedMode:UpdateSchedulers ()

[leaden ice]

That's because you're only looking at the first line of the error

However it's clear that this is an editor issue just from that piece

[reef creek]

Does it mean the error is in the inspector?

[leaden ice]

Could be

Not necessarily

But part of the editor for sure

[reef creek]

I cant find it

😦

[leaden ice]

What are you hoping to find and where are you looking? It's likely a Unity bug. Report and research it, and move on

[reef creek]

Should I just continue my work like nothing happened then?

[leaden ice]

I made my recommendation

[dusk apex]

Is this in regards to custom editor scripting?

[reef creek]

The only third party I using is LeanTween, but I'm not trying to modify the editor, at least I didnt meant to

[dusk apex]

Are you able to determine which object the error is related to?

[reef creek]

I think the problem is related to the Card GameObject, since the error only occurs when I try to move a card from Deck to Hand

[dusk apex]

Maybe you ought to show the code that moves the card from deck to hand.

[reef creek]

Should I create a post to do so?

[dusk apex]

Also, does this occur with nothing else in the scene but the two objects?

You wouldn't want to be investigating something unrelated to the problem - XY problem.

[reef creek]

Yes

Hmmm... Somehow I just closed the program and oppenend it again and now it seems fine again

Idk what happened, but Ill just report it and move on

[static matrix]

is there a way to do like list.indexof but for a 2d array?

might just switch to a dictionary

[knotty sun]

you know indexOf is basically just a for loop under the hood, so write your own

[static matrix]

alright

what is the purpose of this function?????

[robust elk]

How to make the grid follow the object direction, instead pf the world direction???

[knotty sun]

to get a value from a Dictionary based on a key. Returns true if found, false if not

[static matrix]

I mean yeah
but can't you just do if(Dictionary[Key])?

[knotty sun]

no. you can do if (dictionary.Contains(key)). but that does not return the value for the key if found

[static matrix]

ah

[simple egret]

Your version will throw an exception if the key is not present in the Dictionary

[static matrix]

sorry for being stupid

[knotty sun]

this will throw a KeyNotFound Exception if the key does not exist

[static matrix]

really? hasn't done that for me

oh because I used containskey 💀

im just dumb
disregard everything I say

[simple egret]

A d.ContainsKey() followed by a d[] can indeed be simplified down to a single d.TryGetValue() call

[static matrix]

nice

although I was using containskey just for the bool

[knotty sun]

and the TryGet gives you that bool

2 for the price of 1, what's not to like?

[static matrix]

oh lol I think I am about to use tryget like rn
thats crazy

Is there a way to get a unity event from another script in animation? (The animation is on a game object that dosen t have the script), without using another script

[leaden ice]

what do you mean by "get" the event?

Use all the normal means of referencing things.

[unique delta]

i mean to use it in another animation

[leaden ice]

"use it" how?

invoke it?

Add a listener?

[unique delta]

so at a time in the animation something happens

[leaden ice]

Use an animation event

[unique delta]

that s correct

[leaden ice]

As for how to communicate with another script that's just a basic question of getting a reference to it

I am passing input parameters to an abstract class' method. Another class that is overriding the method is receiving the input parameter. However, none of the properties of the input parameter are showing up in intellisense. How do I pass an object via abstract class?

public abstract class EnemyLogic : ScriptableObject
{
    public abstract void Finish(FooClass foo);
}

public class Enemy : EnemyLogic
{
  public override void Finish(FooClass foo)
  {
    foo.??? //(None of the public properties in FooClass are visible or accessible here)
  }
}

[leaden ice]

What does FooClass look like?

if intellisense isn't working it could be a sign that your IDE is not configured properly?

[waxen blade]

It says it doesn't contain any definitions if I do foo.PropertyNamehere, even though I know for a fact the property is there.

    public class FooClass
    {
        public int Digit { get; set; }
        public Vector2 ObjectPosition { get; set; }
        public float YOffSet { get; set; }
        public bool CurrentlyAttackable { get; set; }
        public string ObjectType { get; set; }
        public bool IsSpawnable { get; set; }
        public GameObject SpawnedObject { get; set; }
        public int Health { get; set; }
        public Vector2 HammerPosition { get; set; }
        public Vector2 CurrentObjectPosition { get; set; }
        public Vector2 CurrentDirtPosition { get; set; }
        public GameObject DroppedLoot {get; set;}
        public Vector2 DroppedLootPosition { get; set; }
        public Enemy EnemyData { get; set; }
        public Hazard HazardData { get; set; }
        public TreasureChest TreasureChestData { get; set; }
    }

[leaden ice]

Is your IDE configured?

[waxen blade]

Yes, I only have issues with intellisense in this abstract class.

[leaden ice]

Also do you have any other syntax/compile errors in the code?

[waxen blade]

No.

[leaden ice]

I don't see any reason why IntelliSense shouldn't be picking these properties up

I doubt it's related to the abstract/override thing

Anyway at worst this is an IntelliSense problem. The code you wrote is correct.

[knotty sun]

is FooClass recognised? Missing namespace?

[rigid island]

regen project files ?

[waxen blade]

Unfortunately it's more than intellisense, I can't modify or access the properties.

[leaden ice]

how do you know? What happens?

Are you getting an error?

[waxen blade]

I can't build my code.

[leaden ice]

Why not?

What happens when you try?

[waxen blade]

foo.Digit = 1

FooClass does not contain a defnition for "Digit" and no accessible extension method 'Digit' accepting a first argument of type 'FooClass' cloud lnot be found (are you missing a using directive or an assembly reference?)

[leaden ice]

If you right click FooClass and click "go to definition" or "go to declaration" where does it take you?

[waxen blade]

It takes me to the class.

[leaden ice]

Are you getting this error in Unity too? Or only in VS?

[waxen blade]

Both.

I do see some thing in foo, but none of my properties.

[leaden ice]

I would guess some combination of:

• More than one FooClass defined
• Assembly definitions are involved
• Namespaces are involved

I think I know what the issue is. I had tunnel vision and missed the fact that FooClass has another class wrapped around it. I'll report back soon.

[leaden ice]

ah then yes you need WrapperClass.FooClass

[waxen blade]

But your guess would be on point if this is the issue.

Yes, that was my problem.

I didn't realize that the IDE was trying to help me by automatically adding the wrapper class as a static using statement at the top. So I didn't realize there was a problem since I expected it to work without the wrapper class name.

The IDE has been trying to help me with this the whole time but in the end I think it just made me develop a bad habit. Oh well, now I acknowledge what's going on so I know what to look out for.

Thanks for the help!

[hearty mortar]

So, when it comes to input maps, I've been thinking of creating a combined maps system, where I have say a "Movement" input map, and a "Weapon Sheathed" and "Weapon Unsheathed" input map, and activate multiple at the same time. I do see that this can't be done with the "Player Input" component, but I have more of a theoretical question: does it make sense to represent input map sets as a FSM? It seems like a fairly logical approach. Has anyone tried doing it that way, and does anyone know of any packages (ideally FOSS but if not, asset store) for it?

[leaden ice]

FSM doesn't make a lot of sense to me here unless it's a layered one. From your example here we have a Movement map and then sheathed/unsheathed weapon maps which presumably are independent of the moving one

[hearty mortar]

That's true, I was balancing configuration complexity with programming complexity. I figured not too much work to put the Movement map on all relevant, though yes, layered seems more logical

But more work to implement code-side haha

Since you actually need to keep track of whether edges cross a layer boundary, rather than using a simple graph

Another question, from what I've been reading, Unity's "SendMessage" and "BroadcastMessage" functions aren't great. Do people usually just use hardwired events, or do you roll your own message bus?

[leaden ice]

We usually just call methods normally

When possible and practical

[pastel patio]

How do you guys handle save&load usually?

Mine is a sandbox game which means that there's uh... A Lot to save

[gray mural]

json / prefabs

[pastel patio]

My question's bit more like, if there's for example an undefined amount of varied enemies that needs to be saved, how do people normally go about it?

[gray mural]

json

[leaden ice]

You save whatever you need to save

[pastel patio]

You can't save via a prefab now can you?

[gray mural]

You can. Applying the changes to the prefab won't make it lose them after the game is finished

[lean sail]

The same way you store anything in an undefined amount, a list of these objects

[leaden ice]

If there's information that can be stably derived from a source other than the save, use that. For example if the game involves a procedurally generated map, often you can get away with just saving the map generation seed, rather than all the generated map data.

If it's modifiable later, e.g. Minecraft, you could just save the modifications, rather than the whole world of blocks, for example.

[pastel patio]

Everything is destructable and then you can place new stuff too '^^

[leaden ice]

This is all hypothetical and really depends on the specifics of your game

[leaden ice]

You have two choices:

• Save the absolute state of the world
• Save the info needed to generate the world as well as modifications players make later

[pastel patio]

Well, I've got a terrain manager storing all the data and stuff

But not in a manner just so easily saveable, I believe

[tired apex]

so I may start a aside project that scripted in python , what are my option here do I use https://docs.unity3d.com/Packages/com.unity.scripting.python@2.0/manual/index.html

or better go with iron python inside .net directly

[leaden ice]

If you have a huge amount of data, something like JSON is also not likely feasible for size reasons. You would want to consider either a custom binary format or something off the shelf like protobuf or MessagePack.

in any case though you need to serialize it and write it to a file

[pastel patio]

Uh, okay I'll just ask on commentaries of how I did things so far ig

Uh, might seem quite insane, but I've basically made a whole system centered on structs I named SavedObjects, they basically contain:

A prefab id
An instance id (Index at which they're registered)
An instance code (Security against a new object taking the index of a destroyed object being mistaken as the old one still existing)
A position
A rotation
An array of strings to store extra data

All SaveableObjects are backed with a SavedObject, and persistent references (To bypass the loaded object being unloaded) basically is 2 int with the instance id and the instance code

[swift falcon]

Hey guys, is it possible to toy around with Input System UI Input Module's settings?

programatically

I'd like to temporarily disable ui navigation but i am not very sure how to

[pastel patio]

Y'all see why I'm asking about how you save stuff now? I just wanna fact check if what I did isn't simply insanity 😂

[leaden ice]

seems pretty reasonable. Not sure I totally understand the difference between instance id and instance code

presumably the prefab id is so you know which prefab to instantiate

[lean sail]

The only thing I see necessary is the prefab ID and positions rotation tbh. Strings of extra data dont really make sense, you're gonna have to parse that somehow into something

[leaden ice]

presumably each individual script would know what to do with the "extra data"

e.g. a flower script might know which type of flower had bloomed based on it

but an array of strings is quite freeform

[pastel patio]

id = which prefab
instance id = index in the global registery
instance code increases once everytime something takes over an empty registery

Basically I keep a list of SavedObjects in 1 place

And destroying one only makes that place marked as free space

[leaden ice]

so "global registry" contains all active objects and is basically a list whose slots can be recycled whereas "instance code" is a different system where ids cannot be reused?

I guess I don't see what value that has

Does the order actually matter?

[pastel patio]

SavedObjects are inactive objects, basically the data version of SaveableObjects (Which are monobehaviours, in contrast to the other being structs)

[pastel patio]

Well, you wouldn't wanna removeAt in a list of 330000 objects...

[leaden ice]

no but I wouldn't use a List

I would use a HashSet

[pastel patio]

Literally

[lean sail]

Trying to make just 1 generic save struct for this probably wont work nicely for this. Also using structs here for such a large amount of data is probably worse than just using classes. Also consider that for the string array, you need to parse that data manually into what it is, which can basically be seen as storing json inside a json. I would really just make separate types for each thing that needs to be saved. If it derives from a single thing to ensure it implements the prefab ID then that's easy too

Structs should really just be used with small data

[leaden ice]

Anyway that's a different debate. I can see the benfit this might have at runtime but does it have any benefit in the save file? When you save and reload the game you don't care about objects that used to exist but have since stopped existing, right?

[pastel patio]

Yes, the save file itself kinda of another story

[leaden ice]

Like even if all the object IDs get shuffled when you load, that's not a problem right?

[pastel patio]

Even though the savedobject system essentially already stripped it down to what needs to be saved

[pastel patio]

Nope, it is

Since I keep them structs where references are via an instance id

And why structs, you may ask?

Uhm, I don't think that I'd know how to severe all references to a savedObject once it's destroyed if it's a class

It's a monobehaviour thing

[leaden ice]

Let's say we have:
Red Block at position 4, id 100
Blue block at position 5, id 101
Green block at position 6, id 102

If I save this as a list:
[red 4, green 5, blue 6]

It doesn't matter what order that list is in right? As long as when I reload the game there's a red block and position 4, a green block at 6, and a blue block at 5 right?

And if the new red block's id is 200 instead of 100 that's not an issue right?

[pastel patio]

It has a problem, cus if blue block references red block via his id in the list

You can't legitamately reference a struct, unless if I'm wrong

[leaden ice]

I see, so your objects are actually using this id as a reference somewhere

[leaden ice]

you're correct

[pastel patio]

Even if you can reference a struct, it'd likely become the same issue as using a class

Which basically is, if blue references red, but red gets destroyed, then blue keeps red alive via it's reference

[leaden ice]

really I would just use some kind of ID number but use a Dictionary<object id, object> to access them rather than a list

list order, as you know, is quite annoying to deal with

you can convert to a list and save the id number with the object in the save file, but use a Dictionary at runtime

they are fast for adding and removing objects too

[pastel patio]

Well, that's the funny part, I simply don't order the list, when something is added, it will look through a queue containing free indexes, and if one is destroyed, it just adds it to the queue

[leaden ice]

yeah I'm familiar with this strategy

sort of like a malloc/free thing

[pastel patio]

Yeah

It just have the issue when something takes another's space and gets regarded as the older thing at that registry

[latent latch]

c# hashset and dictionary can be iterated over as it implements IEnumerable

[pastel patio]

I don't quite get that tbh

[leaden ice]

That's only a problem if you have orphan references to objects that are deleted

[pastel patio]

How would you circumvent that kinda issue?

I don't think there's any other choice than references being integers pointing to the index

[leaden ice]

It kinda depends. There's several options and the best one depends on the specific circumstances. You could:

• always make sure that any object referencing any other object gets notified if the thing it's referencing is destroyed, so it can forget about it
• use tombstone objects which are basically never actually destroyed (e.g. just mark it as isDestroyed = true)

Your generic object struct here could implement an OnDestroyed event that referencers can/should subscribe to for the first option.

[pastel patio]

I don't exactly see how either of those can work, in fact, I thought about the first one buuut... It's not gonna work, wanna know why?

[latent latch]

I honestly prefer malloc over automatic* garbage collection as I prefer having errors to things for when I am supposed to have cleaned those up. I feel like it's harder to catch those dangling references otherwise

[swift falcon]

Anybody know?

[pastel patio]

If the referencer gets unloaded first, so the reference becomes merely an integer in data, and then you destroy the one being referenced

[latent latch]

Heck, you do extra work in unity having to make sure you destroy scene objects too, so you're working over time when it comes to making sure you deload your stuff, haha

[pastel patio]

Well, to be honest me and Unity, in that project it's a bit of a love/hate situation

I have to fight unity often times, remaking systems on top of theirs to do what I want

Buuuuut not using Unity is gonna be very troublesome as well

[pastel patio]

Legit I consider what I'm doing some sort of remaking a system on top of theirs, since I essentially defined some sort of gameobject system with what I did (And I often still wish to make more control)

Which is tbh pretty weird, cus in the end you'd nearly assume Unity's system actually has all I need, but maybe hidden away in the depth of the engine

Whelp, ig that I got something out of this, first, I'm not insane nor dumb to have made this system.

Second, the only alternative possible that I avoided is that all SavedObjects are classes, and subscribe to OnDestroy events.

In which case, there's currently 330000+ objects on the surface world, soooo.... 330000 classes each with an ondestroy event......?

[lament gale]

I am trying to dynamically make a "catalog" for the structures in my game. Ive so far instantiated all of the ui elements onto a panel and I want to change another variable depending on the button you press. My issue is that all of the buttons give me 15 instead of the current value of "i" inside of the for loop.
Any fix?

Thanks in advance

[somber nacelle]

https://unity.huh.how/anonymous-methods-and-closures

[lament gale]

Ill try this, thanks alot!!

[rocky basalt]

Can someone tell me how I should format the listener method to get rid of this error?

i'm bad with generics

[somber nacelle]

your OnGrabbed method does not accept a PointerEvent parameter like the delegate expects

[rocky basalt]

Damn, it was that simple. Thank you

I still often get thrown off and confused by stuff in angle brackets haha

[somber nacelle]

it's not even a matter of understanding generics, it's understanding that the UnityAction with a generic type parameter will be passing an object of that type to the methods subscribed

Just like System.Action UnityAction has generic and non-generic versions where the generic versions are basically exactly the same, except they pass one or more parameters

[rocky basalt]

Makes sense. Wish the error message dumbed it down a bit like "arguments requires a PointerEvent type"

[rain minnow]

It kinda does . . .

[rocky basalt]

yea, yeah 😂

[rain minnow]

😄

[slim gate]

So, is this worth it in terms of performance or is there no difference at all:

public bool CanItemFitInInventory(ItemInstance itemInstance, int amount)
{
    // Yes if empty slot available
    foreach (var slot in ItemSlots) { if (slot.Amount <= 0) { return true; } }

    foreach (var slot in ItemSlots)
    {
        if (slot.Amount <= 0) continue;

        if (slot.ItemInstance.Item.Id == itemInstance.Item.Id && (slot.Amount + amount) <= itemInstance.Item.StackSize)
        {
            return true;
        }
    }

    return false;
}

 public bool CanItemFitInInventory(ItemInstance itemInstance, int amount)
 {
     // Yes if empty slot available
     if (ItemSlots.Any(slot => slot.Amount <= 0))
     {
         return true;
     }

     return ItemSlots.Where(slot => slot.Amount > 0).Any(slot => slot.ItemInstance.Item.Id == itemInstance.Item.Id && (slot.Amount + amount) <= itemInstance.Item.StackSize);
 }

I have no idea about LINQ-expressions and dont really understand them too much but my IDE is suggesting this change by itself. Its a method that potentially can get called very often if the player stands on a pile of items so performance would be important here. Not sure if there is any difference between these though? I assume that if the IDE can change these by itself then so would the compiler into the most efficient one.

[mental rover]

In this case I'd imagine no difference. If you're concerned about performance though, iterating the collection twice should be the flashing alarm bell here

[chilly surge]

LINQ allocates, GC pauses might be a bigger concern.

[stable quest]

Hey folks -- I need a quick sanity check. This operation should do nothing, right? Do I have the order correct here?

newAverageRotation = newAverageRotation * Quaternion.Inverse(x);
newAverageRotation = newAverageRotation * x;

(newAverageRotation is a quaternion)

[leaden ice]

It should do nothing, subject to the limits of floating point precision.

What you've got here is basically:

a = a - x;
a = a + x;```

[stable quest]

Thanks, that's what I thought. I can't imagine I'm running into precision issues, but maybe. Something funky is going on.

[leaden ice]

is the result REALLY off

or just like

slightly off

I would expect you to have a small amount of error for basically any value here due to precision errors

[stable quest]

it's slightly off at first, but then it compounds a few times and gets ENORMOUSLY off very fast

[leaden ice]

how many times are you doing this calculation

like once per frame or something?

the errors could compound pretty quickly

[stable quest]

yeah this is an editor script, so once per scene update

[leaden ice]

Could you show the real code here? I imagine the real operation is some more complex thing

[stable quest]

sure, one sec

[leaden ice]

And maybe there's a better way to do this

For example - just storing the original rotation and restoring it afterwards

[stable quest]

so, this is the end result of a lot of debugging: basically, I'm trying to implement some rotation handles in this editor, but in order to do that with multi-select I need to get the difference in rotation and apply it to each selected "viewpoint." for simplicity I've worked out this, which is the simplest thing I can do that still creates the problem. for this example, I'm just applying the rotation to a single viewpoint to see if I can get that to work.

EditorGUI.BeginChangeCheck();
Quaternion newAverageRotation = Handles.RotationHandle(firstSelectedViewpoint.localRotation, averageSelectedPosition);

if (EditorGUI.EndChangeCheck()) {

    Quaternion rotationOffset            = newAverageRotation * Quaternion.Inverse(firstSelectedViewpoint.localRotation);
    firstSelectedViewpoint.localRotation = firstSelectedViewpoint.localRotation * rotationOffset;

    Debug.Log(firstSelectedViewpoint.localRotation);
}

If I set the rotation of the viewpoint to the handle output directly, it works fine

Here's the log output when I start rotating the handle in the editor:

obviously a quaternion shouldn't look like that!

@leaden ice pinging just to make sure you saw this

[leaden ice]

right so this minimum example proves that our problem is due to floating point precision errors right?

[stable quest]

yeah it must be, right? I'm not sure how to fix that, though. normalizing the offset quaternion causes other problems

[leaden ice]

wait isn't thois wrong?

Quaternion rotationOffset = newAverageRotation * Quaternion.Inverse(firstSelectedViewpoint.localRotation);```

[stable quest]

is it? what am I missing

[leaden ice]

nvm

it's not

[stable quest]

maybe i just have to handle this in a different way. storing vectors or something instead of quaternions. cause this is wild

[leaden ice]

What's the goal here? You're trying to get the rotation diff so you can apply it to a bunuch of different objects?

[stable quest]

Yep exactly

[leaden ice]

silly question but like

what happens if you use world space rotations

instead of local

[stable quest]

yeah that is a good idea but these are actually worldspace

[leaden ice]

no parents?

[stable quest]

i just didn't want to rename my variable just for debugging haha. these aren't transforms, just a barebones class that holds a position and rotation

[leaden ice]

Actually wait it may be this

Quaternion rotationOffset = Quaternion.Inverse(firstSelectedViewpoint.localRotation) * newAverageRotation;```

order of operations does matter here

[stable quest]

I'll give that a shot

[leaden ice]

My napkin algebra gives them in that order:

newRot = fsv + diff
newRot - diff = fsv
-diff = fsv - newRot
diff = -fsv + newRot```
But I'm not sure if I did the algebra right given the non-commutability of + here

[stable quest]

huhhhh still broken.

Oh wait a second

okay if I do that AND normalize the diff that seems to work!

[leaden ice]

awesome!

[stable quest]

phew! Thanks so much!

[hearty mortar]

Do we need to manually integrate quantities in our code, or is there a way to piggyback off the integrator Unity uses for physics?

[leaden ice]

in what context?

[hearty mortar]

E.g. applying gravity to a Character controller

[leaden ice]

The way the physics engine integrates is to just use a fixed timestep

No this is not completely physically accurate, and that's ok

[hearty mortar]

Yeah, but I assume the physics engine isn't doing explicit Euler the way the sample assets player script does it

[leaden ice]

it's pretty much just doing this every fixed timestep

velocity += Time.fixedDeltaTime * gravity;
position += Time.fixedDeltaTime * velocity;```

You can verify this yourself

[hearty mortar]

I thought the physics engine was in the C++ core of the engine?

And not open source?

[leaden ice]

Unity uses PhysX

which is an open source physics engine

[hearty mortar]

Ah

[hearty mortar]

Ah, ok, so it's not actually doing this, it's doing

position += Time.fixedDeltaTime * velocity;
velocity += Time.fixedDeltaTime * gravity;

But yeah, it's just semi-implicit Euler

... Wait

No

Damn, my numerical analysis is rusty

No, you were right, it's velocity first then position

Well. Huh, I was expecting some higher order integrator

[tall veldt]

I’m trying to make a instantiated object shopt forward and when i set the velocity to vector2(1,0) it moves but when i set it to transform.forward it stays still, anyone know what the issue could be

[dusk apex]

I'm guessing 2d?

The forward of an object in 2d by default would be the z axis.

You'd probably want to move relative to the object's right (assuming this is 2d)

[leaden ice]

Sorry to disappoint you my dear

[pastel viper]

anyone knows why input field doesnt work on mobile? The keyboard doesnt pop up to allow me to type

[rigid island]

The textmeshpro one ?

[pastel viper]

yea

[pastel viper]

is that the issue?

@rigid island u know a fix?

[spring creek]

Please just be patient

[rigid island]

No it’s not an issue. Not sure what it is then , try googling to see if you need to force keyboard idk I recall it works for me out the box

How are testing mobile exactly?

[pastel viper]

I put the game on itch.io

[tall scroll]

Is it apk or webgl?

[pastel viper]

WEBGL

[tall scroll]

Could be a webgl thing then

I know sometimes it’s a bit buggy

[pastel viper]

is there a workaround?

like how can I implement a game without it breaking like that on mobile?

cuz I was also thinking about adding a virtual keyboard

[rigid island]

that explains it

[fickle moth]

Anyone got any wise tips on how to achieve a tidal lock?

the Moon is tidally locked to the Earth because it rotates in exactly the same time as it takes to orbit the Earth.

I would preferably like to be able to tick a bool which would take into account the moons orbit Speed and distance from planet to moon to always have rotation locked regardless of its speed or distance!

[rigid island]

you can try the old Input or maybe UIToolkit has support out the box for that

[pastel viper]

oh ty

[fickle moth]

private IEnumerator RotateAroundPlanet()
{
    while (true)
    {
        if (planet != null)
        {
            float angle = 0f;
            float rotationAngle = 0f;

            while (angle < 360f)
            {
                // Calculate the position of the moon around the planet
                Vector3 orbitPosition = planet.transform.position + Quaternion.Euler(0, 0, angle) * new Vector3(moonData.orbitRadius, 0, 0);

                // Set the moon's position to the calculated orbit position
                transform.position = orbitPosition;

                // Increment angle based on orbit speed
                angle += moonData.orbitSpeed * Time.deltaTime;

                // Rotate the moon around its own axis
                if (!moonData.isTidalLocked)
                {
                    // If not tidal locked, rotate at the specified rotation speed
                    rotationAngle += moonData.rotationSpeed * Time.deltaTime;
                }
                else
                {
                    // If tidal locked, calculate rotation speed based on orbit speed
                    float orbitalPeriod = 360f / moonData.orbitSpeed; // Time for one orbit
                    float rotationSpeed = 360f / orbitalPeriod; // Rotation speed for tidal locking
                    rotationAngle += rotationSpeed * Time.deltaTime;
                }

                // Apply rotation
                transform.rotation = Quaternion.Euler(0, 0, rotationAngle);

                yield return null;
            }
        }
        yield return null;

}

Nevermind i got it working , heres the coroutine if anyone is interested in it

nice comments

[fickle moth]

i use chat gpt to help with alot of things!

find it easier to use it as an assistant rather than just making it do everything!

lol im not saying make it code everything lol

[somber nacelle]

comments really shouldn't be just stating the obvious though, making that Apply rotation comment pretty useless

[fickle moth]

forsure , that was def chat gpt

[somber nacelle]

and that's one of the many reasons to not use it

[fickle moth]

lol gotta learn somewhere!

makes my life easier , no need for me to add comments or completely restructure something simple when it can do it for me

in the end it still needs human input to be useful

[spring creek]

You can learn many many places. Chat gpt is not even close to being on the list of places to learn

It will actively hold you back, lie to you, hallucinate, and teach you very bad habits

It could be argued to be ok when you have already learned to tell when it is wrong (i would argue the opposite), but it is HORRIFICALLY BAD for beginners

[fickle moth]

i am self taught using tutorials and chat gpt over 2 years, Give me a quiz if you think it has been bad to me im always eager to learn or be corrected!

And yes you are absolutely right it hallucinates alottttt , i cant tell you how many time it has just made up non existent using statements.

[spring creek]

Imagine this, you may have knowledge now, and that is good, but you could have learned faster if you had not been held back by the spam generator

[rigid island]

what will you do if GPT stops working ?

or server is down

[fickle moth]

without it i would have never gotten started!

[fickle moth]

i can code myself!

[spring creek]

Well that is terrifying

[fickle moth]

lol i mean i never had an interest before hand

the ease of being able to have it explain things to me when i ask is amazing

[mental rover]

there's a surprising number of people that have a real burning hatred for AI - I think it's very evidently a great learning tool though, respect for getting things out of it

[fickle moth]

i understand the hatred for it!

I dont like the thought of something being purely AI but if you are able to input your creativity into it and brainstorm with it i think it can be really good!

[spring creek]

The "hatred" is mostly born from the constant flood of garbage people get from it that they expect us to fix here

Spend enough time teaching and helping and you will see it

[fickle moth]

i can see that!

[spring creek]

There is a reason it is against the rules to use it for helping people or to ask for help with code from it

[mental rover]

as opposed to everyone else that always reads the obvious google results and documentation, right? 😂

[fickle moth]

lol i can see if the code hasnt been vetted by the user first

[rigid island]

its not hatred , I could care less what other people do its when the code breaks or isn't a real functional script, people come here to ask for help , which is a waste of time of everyone involved since they also have no clue what you're explaining to them cause they used GPT for everything

[spring creek]

Unironically yes. Because at least that is close. Unlike 99.9% of the code from gippity brought here i misunderstood you. Missed the sarcasm. Yes, people skip docs sometimes. At least THEY are trying. Which is not true of the ones using gpt

[fickle moth]

lol it should just be a pinned message that you are not allowed to post questions related to chat gpt if it needs over 3 references!

its okay with simple things , trying to get it to implement XOR encryption or A* is just not gonna happen

[mental rover]

there's definitely some knee-jerk and unfounded hate for it, see it all the time, people are absolutely frothing at the mouth to insult or downplay how helpful AI can be in figuring out concepts or learning something new, or just as a starting point to give you some keywords to investigate further

it's utterly bizarre how much some people want to hate everything about it - not sure if it's fear or insecurity or what

[spring creek]

I haven't seen that. That's quite sensationalist

I just think it is realism

[rigid island]

yeah dont think ive seen any forthing at the mount hate for it

[spring creek]

And frustration over people suggesting it to beginners, who it WILL harm

[fickle moth]

especially if you use it correctly!

ask it hey what's an interface or what does abstract mean , goes a huge way

[rigid island]

nothing google can't answer though..

and more accurate because you learn critical thinking skills

[spring creek]

See, that is the exact worst way to use it. It will often give a good sounding but fundamentally incorrect response

So many good examples on google

[rigid island]

rather than being sure the Spam generator is being legit

[fickle moth]

forsure but i can talk to it like a person... maybe i dont understand a key point of it

[rigid island]

cause thats really what its meant for.. fake "human-like" interaction

[somber nacelle]

the problem is that most people don't use it that way. rather than using it as a supplement to help them understand concepts that they have been introduced to or as a tool to figure out what they should be learning, they use it as the primary source of learning. so they learn incorrect things because the AI doesn't know anything. it's just a very advanced text predictor like your phone's keyboard has

[spring creek]

Also when people ask for help and someone rolls in and says "i dunno, ask gpt"
Like, if you don't want to help, then don't help
We are here, and willing. No need to send people away

[mental rover]

I'm not sure that's actually true at all, I think that's a perception people have to "other" people who use it, and ultimately to undermine it itself. I understand why it's frustrating to try to help someone who hasn't engaged with a problem they want to solve, but it's little different from the countless other people that ask questions who didn't even bother to google it or look at the unity documentation

[spring creek]

It is definitely true
Hell yeah it is different 🤣
Edit: maybe that's my "frothing hatred" though lol

[cosmic rain]

The issue is the way you use it. You can also google "complete script that does x" and when it doesn't work copy paste it in discord and ask why it doesn't work without any understanding of the code.

It's just easier to do such a thing with ai

[somber nacelle]

it absolutely is true. i don't think you understand just how many times people have come in here trying to get help with AI generated code because they don't understand the code that was given to them and it doesn't work the way they expect. and there are a number of reasons that happens, mostly because people make the assumption that the AI somehow understands anything and expects it to be a good resource to learn from.
it's not. like i said before, it's basically just an advanced text predictor. literally all it is doing is predicting what the next most likely text would be based on its training input. this makes it a terrible tool to learn from, and the best it can be used for is to basically just rephrase other information in a way that (hopefully) makes sense to the people using it, but quite often, especially when it comes to unity stuff, it just makes things up. and then someone who doesn't actually understand the concepts they are trying to learn ends up internalizing that made up info or they come running to here because they heard they need to do something a certain way.

using text generators as a learning supplement is okay provided you already know what you are doing. but of course to already know what you are doing you need to learn from a decent source

[mental rover]

You can't possibly know how many people have used ChatGPT in some capacity and have used it to springboard their ideas or solutions, that have then come and asked questions here though. You're only basing that perception off of the egregious cases that make it obvious they have fully relied on ChatGPT and haven't engaged with the problem themselves

[cosmic rain]

Well, as long as they can show understanding and effort, it's fine if they use ai.

[fickle moth]

I can see the frustration of the new people expecting god like answers out of spaghetti

I used to mod battlefield V and trying to help people swap meshes was exactly like that

[cosmic rain]

No one blames them for using ai specifically. We blame them for using it to cut corners. Important corners.

[fickle moth]

you cant even ask questions unless you understand the basics

[mental rover]

I agree, but that's not the balanced take a few people here are trying to push at all

[spring creek]

Where?

That seems exactly like what boxfriend and I are saying at least
Just that it isn't the norm that we see

[somber nacelle]

it's only a balanced take if you agree with them

[cosmic rain]

I agree that this community is a bit biased against ai based on my experience. But there's nothing you can do about it. And there's no point arguing about it.

[fickle moth]

i think we all have a deep hatred for machines

[mental rover]

That's the thing - you see a bunch of people that are using AI in an unproductive way, and you've made the leap to saying most people/99.9% of people are wasting everyones time, learning incorrectly, AI bad, etc, etc

Someone could come in here and ask a simple question and get a load of useful help. A different person could come in and ask the same question, but also mention they tried to ask ChatGPT first, and they'll get 5 people jumping down their throat like clockwork over how useless AI is and how it should never be used

but it's whatever, you do you I guess

[spring creek]

This is again sensationalist take that is not what is being said. You have this strange desire to twist things into a way more sinister/hard way than they are. Please do not put words in my mouth
I NEVER said that
I am saying there are better and faster ways to learn. And I truly believe that.
It is also a server rule to not use gpt code for help or questions

And I disagree about the part at the end. I see people mention it all the time and get help just fine

as long as they aren't asking for help correcting THAT code, which is against the rules. Which if they are, yeah, people point that out

I should say that I am on every day and scroll back to see what I missed, so maybe I just see the balance more?

[mental rover]

don't forget how this conversation started - a guy asked for help, and then showed that ChatGPT was able to help him arrive at a solution to his question, shortly followed by the lectures on how useless AI is and how it should never be used 😂

[spring creek]

I strongly disagree with that analysis of what happened
It seems like maybe that's just the way you want to see it?

[mental rover]

I mean you can literally scroll up and read it if you like

it's still there

good talk though, I think this conversation has run its course

[spring creek]

They said they resolved it before anyone said anything

And THEY brought up gpt, and people just had a good chat. Mostly until you came and started making it hostile.
Hellfire was doing great and we were just having a friendly discussion, but you called it "frothing hatred" lmfao

But yeah, I'm done

[cosmic rain]

Yeah, this is not a case of help refusal simply due to them mentioning ai.

[spring creek]

@fickle moth
One last thing I DO want to say. Deynai obviously misunderstood the tone of what was being said at the beginning. I want to make sure you didn't feel that way too.

In my opinion, you have clearly been putting in the effort, you even resolved your issue before anyone could respond.
Don't want you to feel pushed away or put down. My comments in the beginning were true to how I feel, but also tongue-in-cheek. I thought that was clear, but clearly not haha.

Anyways. Apologies if you felt insulted or anything. Please do feel comfortable coming back for help whenever you need

[fickle moth]

Never felt criticized at all!

I understand how it is! and i appreciate all feedback!

appreciate you for the kind words!

[spring creek]

Awesome. Glad that is the case!

[keen lantern]

How should I approach plane physics. Someone told me the current way Im doing things is just reinventing the wheels and such. The hiearchy of my plane is an empty gameobject, with plane parts as the children. In this scenario, Im working on implementing a thruster, yet is the thruster is asymmetrical to the plane, torque would make it rotate. How can I, through code (the script is placed on the empty parent), place a force at the position of the thruster, and have torque apply, rather than the whole plane moving perfectly forward when asymetrically placed.

[somber nacelle]

https://docs.unity3d.com/ScriptReference/Rigidbody.AddForceAtPosition.html

[keen lantern]

Does that have torque physics built into it

[somber nacelle]

did you bother reading the page?

[keen lantern]

*guess I can just cl-

was boutta say that lol

ah, literally the first line

If .AddForceAtPosition has torque built into it, then what the point of having a .Torque function in the first place

[somber nacelle]

because they do different things? AddTorque adds only torque to the rigidbody. AddForceAtPosition adds a force at a specified position which also results in torque being applied because the force is not being applied directly in the center of the rb

[keen lantern]

ive not done source gen before in c# is it possible to use source generation so i can create enums on the fly in custom editors ?

im using strings at the moment but not a fan of it

[thick terrace]

it's a bit awkward to set up but rosyln source generators are supported, there's also CodeDom available in editor if you just want a better way of generating a source file yourself

https://docs.unity3d.com/Manual/roslyn-analyzers.html

[broken light]

how would my ide know ive created these enums so i can use them in code without errors of undefined all over the place though

[chilly surge]

IDE knows how source generator works, they can read the generated code.

[chilly surge]

But from this question, I would say source generator is not the right tool for the job.

The best use case of source generator is to "use existing code to generate more code," but it sounds like you want to generate code from assets/editor actions, so it's better to just use a regular editor script that creates and writes to .cs files.

[broken light]

we can edit cs files from editor?

because i need the bit flags of enums which strings dont provide but i need to be able to add / remove enums

but typically enums are hard coded

[chilly surge]

It's just files, you can write to them like you would with any other files.

[broken light]

i see

[swift falcon]

Hi there, i have added this models of a mannequin, and i wanted to add a feature to them but idk how i do it, i wanted to them to make a random audio, but only when i am a little far away, if i am to close then them don't make any sound, but if i am far from them, it would make a random audio.
Does anyone know how to add that feature?

[tired hearth]

Do you guys get angry if I say that I program my game with AI? Lmao

[trim schooner]

Angry? No.
Point out that it's against server rules to ask for help with AI generated code? Yes.

[wide dock]

I couldn't care less, unless you'd come with AI generated code, not understanding what any of it does, and asked us to fix it.

[tired hearth]

Ahhh like that. My issue is, I suck at programming, did try many times. I know how to build the code technically and how methods should communicate etc, I'm just a total 0 IQ when it comes to remembering it etc.

I make up the methods and what they should do and contain and all that. How different methods or even scripts communicate with eachother. I just need help getting the actual code down

[wide dock]

Well, try harder, there's nothing else you can really do. Using AI generated code will just hold you back even more, and with enough practice you'll eventually be good enough to not suck at it

Practice, practice and once again practice

[tired hearth]

Maybe one day

[knotty sun]

I hate to be blunt. Either stop sucking at programming or give up, there is no third option

[tired hearth]

Ayy, time to stop in that case eh

[trim schooner]

You get better at programming by doing, keep doing.. more and more, do different things, etc

You're not expected to remember everything, even experienced devs google simple things because they've not used it in ages and have forgotten

[thick terrace]

yeah, the sign of getting better at programming is being able to find and use more info, not being able to memorize more code

[knotty sun]

I would beg to differ. To use an analogy...
Most people can learn to read and write. That does not give them the ability to become a novelist.

[latent latch]

hey, ive read some terrible books before

[thick terrace]

and some of the best games have terrible code style, lol

yet you'd still consider those who wrote them novelist

What's the fix for unity packages/libraries not being recognized by VS? I've tried regenerating csproj files, deleting Library, restarting VS, restarting Unity
No errors from within Unity it's just a VS issue. Other usings not recognized are:
UnityEngine.UI
NaughtyAttributes

[thin aurora]

Do you use assembly definitions?

[swift falcon]

Not as far as I know but it's not my project. What could the issue be if I was?

[thin aurora]

IF you have those you'd have to reference Cinemachine in your assembly definition since it doesn't recognise it otherwise

[swift falcon]

Ok I don't think that's the issue afaik

[knotty sun]

screenshot your package manage window with 'In Project' selected

[knotty sun]

I think that must be the issue, can you screenshot the project folder where the CameraManager script is

[swift falcon]

The reason I don't think it's the issue is that Unity doesn't complain and compiles fine. Also other people on the project don't seem to have this issue although they are using different IDEs I think

[knotty sun]

Then you may need to ReGen your projects

[swift falcon]

Right now I'm updating VS in case that forces something to fix itself. After that I'll try deleting the .sln file and see if that does something

[knotty sun]

Or just Edit->Preferences->External Tools->Regenerate project files

[swift falcon]

Yeah I've pressed that a good few times

[knotty sun]

which IDE ?

[swift falcon]

VS 17.2.4

Updating rn to VS 17.9.6

[knotty sun]

which Unity version?

[trim schooner]

Ok, but for those who can program.. learn by doing.

[swift falcon]

2021.3.11f1

[knotty sun]

I think you should install at least VS 2019

[swift falcon]

I have VS 2022 sorry should have mentioned that

[knotty sun]

can you screenshot your external tools window

[knotty sun]

Ah, turn off all the checkboxes except Embedded packages and Regenerate

you might want to delete the .sln and all of the .csproj file before doing this

[swift falcon]

Ah that worked thanks! Do you know why you have to uncheck the other boxes?

[knotty sun]

because Unity is absolutely crap at generating working .csproj files

[swift falcon]

Brilliant thanks lol

[fringe ridge]

I make a duplicate of a 3d object, scale it up 10-20 percent, and i need to make sure, that the Y pivots are at the same point. I.e. the Y scale is bigger the same amount on top and on bottom

[tall scroll]

Programmatically or just in the editor?

[fringe ridge]

programatically

tried with Bounds.size, cant get reliable results somewhy

[tall scroll]

Ohhh so the origin isn’t actually the middle?

[rigid island]

just transform.scale ?

[fringe ridge]

Yeah, the character 3d models im using are kinda f'ed up

never in the actual middle

[tall scroll]

I was thinking that but if the origin is a bit below centre it’ll scale more upwards than downwards is what they’re getting at

[rigid island]

So the original pivot is not center ?

[tall scroll]

Mhm

[rigid island]

could make parent object and scale that after offsetting child properly

or just fix the pivot in blender first

[fringe ridge]

there's 30+ objects, I really dont wanna do that in blender 😄

[tall scroll]

Arguably the more sensible choice yeah

[hexed pecan]

So you basically want to 'scale around a point'?

[tall scroll]

Do you know the size of them before being resized? If so the maths shouldn’t be too hard to work out, idk how fucked up your objects are though lol

[fringe ridge]

I actually made it work with the same scale, it looks even better what i was doing, but now i'm kinda interested on what would be the solution

[fringe ridge]

Nope, i tried with Renderer.Bounds.size, but couldnt get reliable results

[fringe ridge]

Yup, I made a shader that glows around the edges of the mesh, and wanted to make the object with shader be a bit bigger than the original object

[tall scroll]

I think that’s easier at the shader level tbh

[hexed pecan]

In that case you could try vertex displacement in the shader

Unless it has hard edges, then it will look off

What I mean is basically adding normal * someScalar to the vertex position

[fringe ridge]

I'll try that, im kinda new to shaders. The objects do have a lot of hard edges

[tall scroll]

How does a normal work on a vertex? Is it an average of the faces around it?

[hexed pecan]

I think it's interpolated from 3 vertices of the triangle
EDIT: Yeah

But yeah hard edges are probably an issue here. They are actually separate faces in unity so it would leave some gaps

[leaden ice]

It could be that but you can actually make it whatever you'd like.

[vapid lynx]

how do i fix that error?

[leaden ice]

Stop trying to use System.Text.Json unless you install it as a DLL in Unity

[vapid lynx]

Do i use Newtonsoft json thing?

[leaden ice]

You can

Or unity's JSONUtility

Either one

[sharp root]

Hello

Im want to make my raycast bigger , i saw that Spherecast is the way to do it

`void LateUpdate()
{
// Check if we are grounded now.
bool isGroundedNow = Physics.Raycast(RaycastOrigin, Vector3.down, distanceThreshold * 2);

    // Call event if we were in the air and we are now touching the ground.
    if (isGroundedNow && !isGrounded)
    {
        Grounded?.Invoke();
    }

    // Update isGrounded.
    isGrounded = isGroundedNow;
}`

What do i change here?

[latent latch]

You probably want overlapsphere, not spherecast

also why LateUpdate

[leaden ice]

Didn't you answer your own question? Use Spherecast instead of Raycast

[sharp root]

Well the problem is , my character (or the fps controller) cant jump when on the edge of an object, basicaly gets stuck on the edge. I know this is a common problem and i think i can fix mine if i just make the raycast bigger

[sharp root]

How tho

[leaden ice]

Wdym

Get used to looking up the documentation for any function you're not familiar with. That's how the rest of us do it. That's what documentation is for.

[vapid lynx]

idk why itsn ot writing to the file?

[knotty sun]

type debugging your json string. I bet it's empty

[vapid lynx]

wait yeah

but i have the object and jsonutility thing

[knotty sun]

so what is it classes need to be before you can serialize them?

[vapid lynx]

huh?

[knotty sun]

you don't know what you are doing do you?

[vapid lynx]

i mean its my first time using json

[knotty sun]

ok, you are trying to serialize your object using json. In order for a class to be serialized is need to be marked as Serializable

[vapid lynx]

this right

[knotty sun]

yep

[vapid lynx]

I alr had the serilaoziable thing

[knotty sun]

not according to this #archived-code-general message

[vapid lynx]

oh i just added it

but like

after i did it still didnt work

[knotty sun]

ok, and where are you expecting the file to be?

[vapid lynx]

in assets

the file is there

its just empty

after i run the code

[knotty sun]

ok, next lesson. JsonUtility does not serialize properties

[vapid lynx]

do i have any?

[rigid island]

uh yea

https://learn.microsoft.com/en-us/dotnet/csharp/properties

what do you think these are? #archived-code-general message

i mean i was just following the unity documentation

and thats what they had

where

[vapid lynx]

which API Compatability level shoudl I be using in the "latest" unity? (I'm on 2022.3*). The docs are really confusing. This page says to "use the .NET Standard" compatibility level, but that is not an option in my Unity. I only see two options, ".NET Framework" and ".NET Standard 2.1". Am I to assume that what they are referring to is the ".NET Standard 2.1"?

And what exactly then is ".NET Framework"? that's also not described in the help pages

https://docs.unity3d.com/Manual/overview-of-dot-net-in-unity.html

Yes .NET Standard 2.1 is .NET Standard

Why can I not use await with LoadSceneAsync?

static async void Init()
{
    DontDestroyOnLoad(Instantiate(Resources.Load("Systems")));

    await SceneManager.LoadSceneAsync(0, LoadSceneMode.Single);

Here is the error
AsyncOperation' does not contain a definition for 'GetAwaiter' and no accessible extension method 'GetAwaiter' accepting a first argument of type 'AsyncOperation' could be found (are you missing a using directive or an assembly reference?)

[rigid island]

AsyncOperation isn't the same as Task

its meant for coroutines
https://docs.unity3d.com/ScriptReference/AsyncOperation.html

[reef garnet]

damn ok, what would you do here then?

this is to load a Bootstrapper as default scene

did you see the example ?
https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.LoadSceneAsync.html

use UniTask too

[broken light]

#if UNITY_EDITOR
        DestroyImmediate(gameObject);
#elif UNITY_RUNTIME
        Destroy(gameObject);
#endif

why cant unity determine the difference for us so we don't have to keep writing this every where -_-

[dusk apex]

Encapsulate the statements in a method and call the method - code reuse.

[broken light]

i have just think unity should've done it from the start

[cosmic rain]

Technically, this is wrong too. UNITY_EDITOR could be play mode as well. And you don't want to have different behavior between play mode and build.

[broken light]

so whats the correct solution ?

[mild coyote]

is this editor script?
if not, any reason why you need destroyimmediate?

[broken light]

well it can be destroyed at run time by a user but i also have an editor script that deletes them

[mild coyote]

ah, that makes sense now

[broken light]

yeah but if unity editor is still possible at run time thats not good

[mild coyote]

although maybe you should have separate script between editor script and runtime script

[cosmic rain]

This https://docs.unity3d.com/ScriptReference/Application-isPlaying.html

[broken light]

ah okay thanks

[cosmic rain]

The reason why you need it is because unity doesn't know if it's play mode or not when it executes you're line of code. That's why it's your responsibility to make that check.

[broken light]

so what does the if unity_editor even mean compared to unity_runtime?

ive seen a lot of people use if defs i guess they don't even realise it either

[cosmic rain]

No clue what unity_runtime is. Can't find it in Google either. It probably doesn't exist at all.
As for the editor define it's to distinguish builds from the editor.

[cosmic rain]

For example, you don't want editor code to be included in a build, so you'd use the editor define.

[broken light]

ah i see

does seem _runtime is not defined or not documented

would it normally not compile if its not defined

or just never occur

[somber nacelle]

yeah the point of a conditional compilation symbol is to only compile code when that symbol is defined. if it is not defined, then the check returns false so it does not compile that code

[cosmic rain]

It would just ignore the code inside as the condition would be evaluated as 0/false.

[broken light]

ah okay fair enough, i think i figured out a new work around ill have the editor script call the destroy immediate then clean up in OnDestroy, rather than call a delete function on the object im trying to delete

[vapid lynx]

I cant find the read input for some reason

[leaden ice]

I'm trying to implement individual post processing for multiple cinemachine cameras but for some reason the volume profiles always seem to be connected somehow. Even if I create new volume profiles for each camera at runtime whenever I change a value on one volume component it always changes the post processing of both cameras. What could be happening here?

    private void Awake()
    {
        m_cameraFreeLook = GetComponent<CinemachineFreeLook>();

        m_cameraPostProcessingVolume = GetComponent<CinemachineVolumeSettings>();
        CloneProfile();

        m_cameraPostProcessingVolume.m_Profile.TryGet(out m_vignette); 
        m_cameraPostProcessingVolume.m_Profile.TryGet(out m_bloom); 
        m_cameraPostProcessingVolume.m_Profile.TryGet(out m_chromaticAberration); 
    }

    void CloneProfile()
    {
        VolumeProfile clonedProfile = Instantiate(m_cameraPostProcessingVolume.m_Profile);
        for (int i = 0; i < clonedProfile.components.Count; i++)
        {
            clonedProfile.components[i] = Instantiate(clonedProfile.components[i]);
        }
        m_cameraPostProcessingVolume.m_Profile = clonedProfile;
    }```

Hello, I am also making a puzzle game, and I have about 25 levels, however I can not find the perfect way to save the level on which the player is so that when he presses play he goes to that level, can anyone please help me?

[mellow hill]

You can save/persist in a number of ways, the simplest approach for something like that would be to use PlayerPrefs but personally I would look into saving/loading via JSON

[wide dock]

I'm not entirely sure, but you could possibly just do this:

public void SaveProgress()
{
  int activeSceneIndex = SceneManager.GetActiveScene().buildIndex;
  // Save either via PlayerPrefs or JSON if there is more data
}

public void LoadProgress() // Call when pressing Play
{
  int sceneToLoadIndex = // Load either via PP or JSON
  SceneManager.LoadScene(sceneToLoadIndex);
}```

Does DoThis have any parameters? If not, you can just .FadeIn(DoThis).

[upper pilot]

Yeah but what is the type of "DoThis"?

public void FadeIn(Callback callback)

[chilly surge]

Are you implementing FadeIn and you are asking about what type the parameter should be?

[upper pilot]

yeah

[chilly surge]

That would be Action.

[upper pilot]

Thanks

[high trail]

Unity is refusing to acknowledge collision and I am about to fail a class because of it

[upper pilot]

Are they both on same Z axis(not sure if that matters for 2D games, but I assume it might)

What about 2d matrix?

[high trail]

yes

wtf is a 2d matric

[upper pilot]

Is any one of them set to "IsTrigger"?

[high trail]

no

[upper pilot]

Then show some code

Do they have rigidbodies?

I am pretty sure rigidbody2d is required

If its 2d game, then you should use colliders2D + rigidbody2D

[high trail]

they do

[upper pilot]

Not sure what is sleeping mode in rigidbody, but check if its not "start asleep"

[knotty sun]

this is not 20 questions, screenshot the inspectors of both objects and show your !code

the top one is not working

[knotty sun]

well you have obviously done no debugging whatsoever

[high trail]

I have no idea how to do any of this I am trying to not get an F in a class that ends in 56 minutes

I don't give a rat's ass about debugging I want to pass

[knotty sun]

then you deserve an F if not lower

[upper pilot]

I thought F is lowest?

Sounds weird when someone say "I want F to pass" lol

[knotty sun]

in my day it was U - Unclasified

[high trail]

That's not what I said

[upper pilot]

Tbh even if it doesnt work, I assume you'd get more than an F for trying?

[high trail]

nah

[sleek bough]

Then you better start learning how to debug issues fast.

https://unity.huh.how/debugging

[upper pilot]

If they taught you basics of debugging then this should be few minutes of going through code step by step in debug mode.

[high trail]

I don't even know how debug mode would be activated

[upper pilot]

I can assume that your objects dont have proper tags so your script is not detecting them.
Also OnCollisionEnter2D should be on a weapon or an enemy, so I dont know why you'd check for tag weapon and name of enemy.
I could be wrong tho.

[sleek bough]

I provided you with a link.

[knotty sun]

you ain't gonna even come close to passing if you don't start to 'give a rats arse' and damn quick

[upper pilot]

Yeah tbh why do I care more than he does, good luck 😄

[high trail]

I would love to learn something that takes months in 20 minutes I really would however that is not possible

[knotty sun]

it doesn't take months, it takes 5 minutes

and you still have not provided the requested screenshots

[high trail]

what screenshots?

debugger will not even allow me to place a breakpoint

[knotty sun]

#archived-code-general message

[leaden ice]

You marked your collider as a trigger

[knotty sun]

So this was a lie

[leaden ice]

Yeah we can't blame Unity for this one

[high trail]

not originally

that got changed

[leaden ice]

Oh the gremlins changed it!

Pesky gremlins

[high trail]

it was changed as troubleshooting ie it was already not working

<@&502884371011731486> these people are being incredibly condesending

[leaden ice]

Do you want the mods to castigate us or didn't you have a class you were about to fail in 34 minutes?

[vagrant blade]

What would you like me to do for you, here?

[tall scroll]

Back in my day we didn’t have access to discord during our finals

[upper pilot]

Tbh for his use case, he needs a trigger I think 😛

[high trail]

Back in your day people were decent. I guess you aren't like your generation then.

[thin aurora]

You would not have to if you just start your project on time unlike this guy

Bugfixing is one thing, but having to make your game even playable in general an hour before the deadline just reeks of improper planning

[high trail]

Nobody asked you

Literally nobody

Not one person

[tall scroll]

I’m 20, if you paid any attention in class you would de-facto not have this issue. We refuse to help you pass class if you couldn’t learn the basics. Come back after the finals when you’re willing to learn.

[vagrant blade]

Issue is solved, everyone can go about their day now.

[high trail]

"solved"

I guess you just allow people to act like animals in your server

[upper pilot]

Nobody asked

[sleek bough]

@high trail If you don't have a Unity related question don't post off-topic here

[high trail]

Wow.

[tall scroll]

In their defence they did

[quartz folio]

Just entitlement from the start and you wonder why you're getting this response

[sleek bough]

And they are preoccupied with bickering instead

[vagrant blade]

Well, only 20 more minutes before their supposed class ends. Good luck to them. 👍

[tall scroll]

Yeah let them bicker for 25m longer and maybe they’ll take the hint from an F

[upper pilot]

I have a general code question about booleans.
I have a Transition screen script and I store few booleans:

    public bool isFadingIn { get; private set; }
    public bool isFadingOut { get; private set; }
    public bool isFadedIn { get; private set; }
    public bool isFading { get { return isFadingIn || isFadingOut; } }

That 3rd boolean "isFadedIn" is a state between fadedIn and fadedOut which means that screen is black.
I use this state to change a scene.

Should I just use enums for a state?
i.e.

public enum
{
  None, // After faded out it goes back to this initial state
  FadingIn,// progressing through fading in
  FadedIn, // finished fading in
  FadingOut, // progressthrough through fading out
  FadedOut, // Finished fading out
}

[latent latch]

either way

well, I mean you could only be in one state so enum would make sense

[high trail]

Have you tried debugging?

[upper pilot]

I'd still keep isFading probably

[upper pilot]

This is not a question that debugging could solve.

[high trail]

Excuses

[quartz folio]

!mute 428784312834326529 24h come back tomorrow without wasting other's time

[tawny elk]

pk_spartan was muted.

[tall scroll]

Sometimes I do feel like programmers gatekeep

And other times people learn to code mid-final

[gray mural]

Yes, I would use enums in this case

[thin aurora]

Generally a "state" would be determined with an enum because you can easily check a single property rather than multiple. You can also easily handle an order if it matters, since an enum is a number.

[upper pilot]

Actually I just realized...in my script I don't always move from fadeIn to fadeOut

for example, I can fadeIn(screen is black) then do nothing until my other script decides to fadeOut

so a state would have to know when to wait.

https://paste.ofcode.org/SvtKpTR5dxd6uvqz2jXqwR

Wall of code, anything that could improve it?

its just changing alpha lol

Posted a link instead, for something so basic like changing alpha you'd expect less code right? 😄

I can probably move a variable for tempColor outside the if statement

[chilly surge]

Personally these are the types of stuffs that work really well if you wrap them in async/await.

[quartz folio]

And/or using a tweening library

[upper pilot]

I havent gotten to tweening library yet, but I have it bought for my personal project so I will start using it soon 😄

[trim schooner]

DOTween has extensions for it all

[chilly surge]

Once you have them wrapped up, usage becomes extremely simple:

async UniTask TransitionToNextLevel()
{
    await FadeIn();
    await LoadNextLevelOrSomething();
    await FadeOut();
}

And if you want to start loading right away without waiting for fade in so that the loading time is shorter for the player? Also easy to express:

async UniTask TransitionToNextLevel()
{
    // Loading starts right away in the background
    var task = LoadNextLevelOrSomething();

    await FadeIn();
    await task; // Make sure loading finishes by this point
    await FadeOut();
}

[trim schooner]

you'd just do myImage.DOColour(); and the 2 or 3 params it needs

[upper pilot]

oh I like that

How do you make sure that loading is finished tho?

scene loading I mean

[chilly surge]

Because you await it, so it must finish before moving to the next line of code.

[latent latch]

public class Fade : MonoBehaviour
{
    public enum States
    {
        FadingIn,// progressing through fading in
        FadedIn, // finished fading in
        FadingOut, // progressthrough through fading out
        FadedOut, // Finished fading out
    }

    private Dictionary<States, Action> stateDict;
    private States currentState;

    private void Start()
    {
        stateDict = new()
        {
            {States.FadingIn, () => FadingIn()},
            {States.FadedIn, () => FadedIn()},
            {States.FadingOut, () => FadingOut()},
            {States.FadedOut, () => FadedOut()},
        };
    }

    public void Update()
    {
        stateDict[currentState].Invoke();
    }

    private void FadingIn() { }
    private void FadedIn() { }
    private void FadingOut() { }
    private void FadedOut() { }
}```

that's my idea

[upper pilot]

I never worked with await, so I'd have to check

[upper pilot]

That looks clean

[latent latch]

just having a general fading tween sounds good

[hexed pecan]

Note that their example uses UniTask

Which is async/await but with coroutine-like functionality (afaik)

[knotty sun]

why not an Array instead of the Dictionary then use the Enum as the index?

[latent latch]

yeah that sounds good too

but dictionary is love

[upper pilot]

oh UniTask is not built in Unity

[chilly surge]

You don't need to use a dictionary, you can just use pattern matching.

[latent latch]

is there difference between a switch and pattern matching

[gray mural]

No?

[upper pilot]

So in this example you need to make currentState public? Since I usually want a control over it.
Specifically I want to only do FadeIn sometimes, then I do fadeOut on OnSceneLoad

[latent latch]

ide always recommends me to change them into a pattern matching state

[upper pilot]

    private void OnSceneLoad(Scene arg0, LoadSceneMode arg1)
    {
        if (TransitionScreen.Instance.isFadedIn) TransitionScreen.Instance.FadeOut();
    }

I check if the screen is black then I fade out on scene load

[gray mural]

Well, it's just a simplified switch, which cannot be used when the block has more than 1 line.

[upper pilot]

Is that await idea possible without installing packages?

[gray mural]

So you can always make a normal switch out of the short one, but not otherwise

[chilly surge]

Generally not really, except that switch statement has statement semantics, and switch expression is, well, expression.

[upper pilot]

so I can do:

await FadeIn();
await ChangeScene();
await FadeOut();//after new scene is loaded

Does code run during scene switch? Should I do async scene load(I think there is such a thing, but it might have a different use case?)

[thick terrace]

yes, Awaitable is available in unity 2023 and does the same thing, otherwise you can just use plain old System.Threading.Tasks.Task for that case, it's just not as efficient in some ways

[chilly surge]

async/await is built into C# as well.

[upper pilot]

    IEnumerator LoadYourAsyncScene()
    {
        AsyncOperation asyncLoad = SceneManager.LoadSceneAsync("Scene2");

        // Wait until the asynchronous scene fully loads
        while (!asyncLoad.isDone)
        {
            yield return null;
        }
    }

https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.LoadSceneAsync.html

Seems like something I might want to use for my case?

[chilly surge]

Enumerator based coroutine is basically a caveman version of async/await.

[hexed pecan]

Theres no way to sync up with the Unity game loop though, right?

Such as waiting for a frame

[upper pilot]

But your example uses UniTask which seems to not be part of Unity?

[chilly surge]

Correct, which is what UniTask gives you.

[thick terrace]

it functions nearly identically, it's really down to which one suits your code better... like often loading scenes you don't want to run a coroutine on an object, because your objects are going away with your old scene haha

[hexed pecan]

Indeed. They were asking about byiltin ways

[thick terrace]

you don't need any third party code to wait a frame

Task.Yield works fine for that

[upper pilot]

Is UniTask in asset store? I only found some github page and I am not a fan of installing packages outside of Unity or in general as I will have to remember it for all of my projects if I want to keep using it.

[latent latch]

git

[thick terrace]

if you want to go vanilla only, regular c# async/await is totally fine, UniTask just has some convenience features and allocates a little less

[hexed pecan]

I was under the impression that Task.Yield is not guaranteed to wait just one frame

[thick terrace]

try it and see!

the unity sync context updates once per frame like coroutines do

i believe some time between Update and LateUpdate

[upper pilot]

Any recommended (game related) examples of async/await to learn from?
I never use those nor do I use IEnumerator in my games and I am probably losing on a lot.

I used a bit of those in the past, but it didnt stick with me.

[thick terrace]

there's some examples in the unity docs https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Awaitable.html

[chilly surge]

Oh TIL, that's cool.

[gusty aurora]

Is there any situtation where there would be a difference between Component.name and Component.gameObject.name ?

[knotty sun]

no

[gusty aurora]

If not, which one is faster / better practice ?

[knotty sun]

they are the same

[chilly surge]

Besides Unity specific stuffs, you can also learn about async/await in regular C#.

[quartz folio]

They are both the same and bad practice. Names should be considered a debugging or prototyping tool and should rarely be relied on.

[hexed pecan]

I believed you, but tested it anyway, and yeah you right 👍 Maybe I had been lied to or I'm mixing it up with something else

[thick terrace]

it's not "guaranteed" in the sense that it's not officially documented exactly how it works anywhere, so you should probably use Awaitable in 2023+, but you can rely on the implementation to work a certain way in older versions

[hexed pecan]

This message is probably what originally confused me 😄

Yeah I'll use Awaitable once I go 2023

[thick terrace]

iirc there actually is a very minor difference depending on when you await, because it can return control to you on the same same frame you started from if you await before the point in the loop the sync context updates... but most of the time i use Task.Yield it's in a loop waiting for something, so it's not a huge difference

and you can write a small wrapper checking the frame number if it does matter

[novel bough]

Hi friends, I am generating a grid of objects at runtime and deleting them at runtime by clicking on them, and I want to show the number of tiles available on each side and also on the cut like showing in the image all sides (6 - 4 - 4 - 6) and on the cut (2 - 2). so how can I easily do this. thanks!

[leaden ice]

Seems like a relatively simple algorithm that walks around the perimeter of the shape, counting up until it reaches either empty space or a block in front of it.

[vagrant blade]

Might be easier to do something like going through each row, and then iterating through the spots on the row before and the row after. When you find an empty space, count it and keep going until you don't find another empty space. Take that number and put the number half way between the number of spaces you found.

Then rinse repeat for the columns

[magic harness]

Hey guys, im having some trouble dealing with my scene management system.

For some reason my MainMenu scene is not unloading whenever i call the startGame function

as you can see, i've tried some things already

 public IEnumerator StartGame()
    {
        SceneManager.SetActiveScene(bootstrap.LoadedScene);
        UnloadScene(mainMenu.BuildIndex);
        yield return UnloadScene(mainMenu.BuildIndex);
        AsyncOperationExtensions.AsTask(SceneManager.LoadSceneAsync(HUDScene.BuildIndex, LoadSceneMode.Additive));
        yield return LoadAsActiveScene(gameplayScene.BuildIndex);
        
        isGameStarted = true;
    }


 public IEnumerator UnloadScene(int index)
    {
        AsyncOperation asyncUnload = SceneManager.UnloadSceneAsync(index);
        while (!asyncUnload.isDone)
        {
            yield return null;
        }
    }

Would appreciate some help, it is not my only loaded scene neighter it is the active scene whenever i unload it

[leaden ice]

How and where are you calling StartGame()?

Also this will do nothing on its own
UnloadScene(mainMenu.BuildIndex);

[magic harness]

ok.. but the coroutine will, wont it?

[leaden ice]

yes

[magic harness]

im calling it from an object in the MainMenu

[leaden ice]

show the code for that

[dusk apex]

You need to start coroutines the proper way: StartCoroutine

[trim schooner]

I've not used AsyncOperation .. doesn't this also need calling?

[leaden ice]

But yeah what's with AsyncOperationExtensions.AsTask(SceneManager.LoadSceneAsync(HUDScene.BuildIndex, LoadSceneMode.Additive));

[magic harness]

private void OnCharacterSelected(CharacterData character)
{
StartCoroutine(SceneHandler.instance.StartGame());

}

its called from an Ui Button

[magic harness]

its just me trying to be able to load scene asynchronously so i can add loading screens later on

[leaden ice]

SceneManager.LoadSceneAsync does that already

anyway have you tried adding logs here?

TO make sure all the code is running as expected?

[magic harness]

i mean, the HUD and the gameplay scene load as expected

its just the main menu not unloading for some reason

[leaden ice]

soo add some logs to the unload scene coroutine?

make sure it's fully executing as expected

I mean presumably the coroutine is finishing if it's getting to those lines

do you perhaps have multiple main menu scenes open?

[magic harness]

thats it, i had an unloaded main menu scene i was working on in the hierarchy

thanks!

[fervent furnace]

extend from Osteel solution a little bit, you need to make one look up tables with size = AABB of the shape extend by one row and column for different size eg if the AABB is 4x8 then the look up tables should be 6x10, then perform the scanning
eg if you have a shape and scan row by row
XXXXXXXXX
XAAAXXXAX
XAAAXXAAX
XAAAXXAAX
XAAAXAAAX
XXXAAAAXX
XXXXXXXXX (X means empty and A means there is a tile)
then your look up tables when finding the left perimeter should be
000000000
100000100
200001000
300002000
400010000
000100000
000000000
and your look up tables when finding the right perimeter should be
000000000
000010001
000020002
000030003
000040004
000000010
000000000
basically for the left size, table[r][c]=table[r-1][c]+1 if grid[r][c+1] (right cell) is not empty and grid[r][c] is empty else 0, the look up tables is filled with 0 first, after assigning the perimeter for one side, reuse the look up table
your next task is getting back the perimeter from the look up tables and assign the perimeter back
your problem not that difficult, but many edge cases
(the size of look up table can be smaller btw)

[candid coral]

Greetings, I am struggeling with an issue, if anyone has time to look at. Using Vuforia, I want to make so that when both ImageTargets/Objects are within the ARCamera View, they rotate. So when one is not within the scope of the Camera, then the other one that is, does not rotate.
As shown in the images, this should do the job. However, this does not work. What's even more strange, I have tried making logs and finding unusual feedback.

Situation 1: Without changing anything. Cube and Cylinder alternates between true and false, when it should be always true since they are within the scop of ARCamera, so they should always behave like "OnTargetFound".

Situation 2: In the imageTarget's inspector, I checked onTargetLost box, so now when the object is not within ARCamera View, it also returns true. But the log is still returning false somehow.

Situation 3: I changed the code to be:

public class ObjectRotationManager : MonoBehaviour
{
    private GameObject cylinderObject;
    private GameObject cubeObject;

    private bool cylinderInTargetView = true;
    private bool cubeInTargetView = true;

    void Start() {
        cylinderObject = GameObject.Find("Cylinder");
        cubeObject = GameObject.Find("Cube");

    }

And I am still getting falses.
However, if I put this

cylinderInTargetView = true;
cubeInTargetView = true;

inside void Start(), now it returns true always. However, it always returns true, even when the object is out of ARCamera view.

I am rather disoriented and would appreciate any feedback on this topic.
