[hidden flicker]

This is the code

The object always has a connectedobject assigned

And yet it attempts connect

And it passes the condition of NOT having an object assigned, even when it ALWAYS has an object assigned

Actually, it DOESNT always have an object assigned apparently

Even though nowhere in the code does it remove it

Connectedobject isnt modified anywhere in the code

At all

[cosmic rain]

There are only that many options:

• it's never assigned
• It's removed at some point

Proper debugging would help figure that out.

[hidden flicker]

It's assigned at all times, except seemingly when something with a WireConnector script collides with it

It's initially assigned in the inspector

And it's not like it gets unassigned or anything

It always shows up

[cosmic rain]

Can you start from clarifying what exactly is assigned or not assigned?

[hidden flicker]

the connectedObject variable

[cosmic rain]

Okay, and the exact issue is?

Are you getting a null reference or something?

[lament island]

Trying to serialize a hashset for use in the editor but I don't seem to be able to actually edit the list to make changes

[System.Serializable]
public class SerializableHashSet<T> : ISerializationCallbackReceiver
{
    private HashSet<T> hashSet = new HashSet<T>();

    [SerializeField]
    private List<T> serializableItems;

    void ISerializationCallbackReceiver.OnBeforeSerialize()
    {
        this.serializableItems.Clear();
        this.serializableItems = new List<T>(this.hashSet);
    }

    void ISerializationCallbackReceiver.OnAfterDeserialize()
    {
        hashSet.Clear();
        foreach (T item in this.serializableItems)
        {
            _ = this.hashSet.Add(item);
        }
    }

    public bool Add(T item) => this.hashSet.Add(item);

    public bool Contains(T item) => this.hashSet.Contains(item);
}

What am I doing wrong here?

[hidden flicker]

I am supposed to be getting a reference. I always do, except for when the object collides with a WireConnectorObject, the reference becomes null and the else condition passes

[cosmic rain]

How/where do you know that the reference becomes null?

[hidden flicker]

A Debug.Log(). When the (connectedObject || connectedSocket) case does not pass, I print what connectedObject is. It returns null

[cosmic rain]

What's with that underscore in deserialize?

[cosmic rain]

This??

if (connectedObject || connectedSocket)
        {
            Debug.Log(gameObject + "passed first case");
        }

[hidden flicker]

Yes. I print the value of connectedObject if that or condition DOESN'T pass, and it prints that connectedObject is null

[cosmic rain]

I don't see any debug log printing the connectedObject

[hidden flicker]

Yeah, I added it in after the fact

[cosmic rain]

Share the updated code then

[hidden flicker]

https://hastebin.com/share/upuhetasik.csharp

I mean, there aren't any other changes other than a log

[lament island]

my bad, that was an old version with some non working parts. Here is the corrected code

public class SerializableHashSet<T> : ISerializationCallbackReceiver
{
    private HashSet<T> hashSet = new HashSet<T>();

    [SerializeField]
    private List<T> serializableItems = new List<T>();

    void ISerializationCallbackReceiver.OnBeforeSerialize()
    {
        this.serializableItems.Clear();
        this.serializableItems = new List<T>(this.hashSet);
    }

    void ISerializationCallbackReceiver.OnAfterDeserialize()
    {
        hashSet.Clear();
        foreach (T item in this.serializableItems)
        {
            this.hashSet.Add(item);
        }
    }

    public bool Add(T item) => this.hashSet.Add(item);

    public bool Contains(T item) => this.hashSet.Contains(item);
}

[cosmic rain]

Well, I don't see you assigning that variable anywhere, so for example, if it's a new component or instance, it might not have it assigned. If anything, I'm not sure how you can be so confident that it's assigned with that code.

[cosmic rain]

Assuming the serialization callbacks are called correctly, I don't see any issue.

[raven orbit]

im watching a tutorial, and it is a bit too advanced for me and its hard for me to understand the code hes writing

[lament island]

right? That's what I thought

[raven orbit]

should i watch a more simple one?

i cant find anything more elaborate

[cosmic rain]

You can confirm that by adding a debug log.

[hidden flicker]

I put code in update to, if it has a connectedObject reference, print that it has a reference. They all do

This has to be a Unity glitch

I'm so confused

[hard estuary]

I would suggest modifying both structures at the same time, e.g.:

public bool Add (T item)
{
  hashSet.Add(item);
  seriaizableItems.Add(item);
}

That way you ensure structures have the same content at any time.

[cosmic rain]

Add a second parameter to the debug log passing in this. When the null message prints, click it and it should select the object that printed it.

Then you can confirm if it has the reference assigned or not.

[hard estuary]

It's worth searching terms like "basics" or "for beginners", cause such tutorials would be created with beginners in mind. After watching such videos it will be easier to transition to more complex ones.

[raven orbit]

alright, thank you

https://youtu.be/8eWbSN2T8TE?si=YX9baBeVqyF2QFlB just in case ill send the tutorial (im not asking for help on it)

[hidden flicker]

I'm not sure what to tell you

I did this

I didn't really learn anything new

[proven jasper]

Depending on your settings, it's possible that you fixed it awhile ago and your domain just didn't refresh until now.

[hidden flicker]

They all have the reference until suddenly they don't

[cosmic rain]

Then it's unassigned somewhere. Remember that destroyed objects are also considered as null in unity.

[proven jasper]

You could use a property and throw a debug.log whenever the value is changed to see where it's being altered from

[hidden flicker]

The object is never destroyed

[hidden flicker]

That's the problem - the value is NEVER CHANGED

[proven jasper]

apparently your result says it is though

[hidden flicker]

I know 😭😭😭😭

[proven jasper]

So just make it a property and check

[hidden flicker]

What do you mean

Like show it in the inspector?

[proven jasper]

No just use a C# property and a backing field

[hidden flicker]

Not sure what those are

[proven jasper]

        public string Property
        {
            get => _backingField;
            set
            {
                _backingField = value;
                Debug.Log($"Property has been changed. {value == null ? "Null" : value}");
            }
        }```

[hidden flicker]

I don't think this will help me. I have an equivalent of this already

[proven jasper]

That's not an equivalent

Your way isn't working apparently, so just try

[hidden flicker]

Ok

Where do I put that code

[proven jasper]

use your original variable name for the property so you don't need to change any code and just add a backing field.

that way all changes flow through the property

[hidden flicker]

Really quick question - if an object gets floating point errors can that make it lose a reference

[proven jasper]

floating point error is just mathematical inaccuracies building up, not an actual exception, so no

[hidden flicker]

I really don't know how to implement the backing field thing

[hard estuary]

This video doesn't explain the basics, but it should be easy to understand for people who already know them. I assume the creator haven't explained the basics, because AI patrolling seems like a moderately complex topic (which implies that people with moderate knowledge will watch it), and he assumed everyone who doesn't understand the basics will watch his previous videos. Here is his playlist of videos about basics:
https://www.youtube.com/watch?v=pFeWUSWHIdk&list=PLBIb_auVtBwD5ovBwgGKbQK8d7efdKGlk

[raven orbit]

thank you, i really appreciate this ill watch it right now

[proven jasper]

skim this https://www.w3schools.com/cs/cs_properties.php

it's a concept you're going to want to be very comfortable with anyway, so worth spending a few minutes on

the tl;dr version is that if my code has Property = "bob" then first _backingField will be set to Bob, and then it will log. It's a handy way to monitor and act on incoming changes

If we wanted to add an OnChange event whenever our variable was changed for instance, we'd just stick it right there in the setter and ensure nothing was accessing the backing field except that property (which is super easy to confirm in your IDE)

[hidden flicker]

Restarting Unity seems to have fixed it

[proven jasper]

lovely

[trim rivet]

I'm trying to add a field to my SO that calculates the sum of other variables in realtime, but I can't seem to get it to display (even using NaughtyAttributes)
Does anyone have any tips on solving this?

[lean sail]

u can tell unity to serialize the backing field of that property with
[field:SerializeField]

[trim rivet]

I thought so too and tried that but it doesn't draw the field and pops out this error ' 'field' is not a valid attribute location for this declaration. Valid attribute locations for this declaration are 'property'. All attributes in this block will be ignored.' 😤

[thick terrace]

that only works for properties that have a backing field, Base_Total doesn't

[lean sail]

ah my bad i didnt even fully read to see this was just a getter

[trim rivet]

what's a backing field? 😮 brb googling

[thick terrace]

i don't use NaughtyAttributes so i don't know what it supports but in plain unity you'd need to write a custom editor for that type to display a property like that, it'll never be touched by unity serialization since it's effectively just a method

[trim rivet]

that sounds more complicated than it's worth tbh

[lean sail]

couldnt u also just give it a private set?

[thick terrace]

yeah i just bought odin for stuff like this 😛

[thick terrace]

only if you deleted the current getter so it was an auto-property, which defeats the purpose i think

[modest brook]

hey guys, how can i make an object lock to the cursor? i wanna make a flashlight stick to the cursor the whole time
i have a custom cursor as well currently and a cursor manager and this is the code i have:

`void Start()
{
cursorHotspot = new Vector2(cursorTexture.width / 2, cursorTexture.height / 2);
Cursor.SetCursor(cursorTexture, cursorHotspot, CursorMode.Auto);

flash.transform.position = 

}`

[knotty sun]

trying to do anything in Start will achieve nothing. you need to lock your flashlight to the mouseposition in Update

[lusty zephyr]

1. Get position from mouse
2. Calculate angle from object towards mouseposition
3. Set rotation of object with calculated angle

[little meadow]

You may be able to just set transform.forwrd/up/right to the direction-to-mouse vector

unity error while evaluating property 'namespace' of task ':unityLibrary:packageReleaseResources'. See the Console for details.
i get this error when i try to make an android build, what should i do ?
and i started getting the error after switching from unity 2022.3.8f1 version to 2023.2.16f1

[knotty sun]

why would you switch from an LTS version to a non LTS version ?

[deft dagger]

i want to use the addressables for android asset and its only available on 2023 versions

[knotty sun]

in that case at least go to the latest Unity 6 Preview version

[deft dagger]

umm im not sure what that means tbh

[knotty sun]

Unity 6 Preview is what would have been under the old naming convention 2023.3

[deft dagger]

this ? @knotty sun

[knotty sun]

yep

[deft dagger]

ok i will try it out, thanks man

[trim schooner]

Adressables are available in much lower versions than 2022... is 'Addressables for Android asset' something different?

[deft dagger]

yeah sadly

[trim schooner]

What's this from? Link

I've been using addressables on Android in 2021..
🙂

[deft timber]

https://docs.unity3d.com/Packages/com.unity.addressables.android@1.0/manual/requirements-and-compatibility.html

[deft timber]

yea same, i wonder why it says 2023.2

maybe older adressable package version works on older unity versions

[trim schooner]

Right, this is an addon to the Addressables package

[deft timber]

yea, it's com.unity.addressables.android package

[trim schooner]

The Addressables for Android package works in conjunction with the Addressables package to support Play Asset Delivery and provides you tools to pack Addressable groups into Android asset packs. This way you can take full advantage of asset pack based dynamic delivery.

[deft dagger]

what do i have to do ?

do i just download git ?

[orchid yacht]

I have been thinking and want to understand how to properly build the logic with Zenject. I may have MonoBehaviour components, but I think it's not just about using two interfaces and "cluttering" the container with dependencies that always need to be injected into MonoBehaviour through a custom constructor method.In general, I am thinking of starting to create objects from prefabs at the moment of initialization/dynamically. Here, I don't fully understand the correct approach. Yes, there should be a service that handles configuration delivery, and a factory (here, I don't want to use a Placeholder because I think it will require a lot of injections and writing code, which isn't a problem).Suppose I have a player who will have scripts like PlayerSpawnPoint, IPlayer, PlayerProxy (can it be used to hide the implementation? Here, too, I don't understand if it's necessary to use an interface for the factory and proxy implementation - I think not). Some kind of PlayerBehaviour and so on will also be needed, and everything should be covered by a facade.It's interesting to create the player at the level of GameObjectContext, that is, through PlayerInstaller or not.
My main problem is that I don't fully see the application architecture. Of course, many implementations are possible, but I want to finally try dynamically creating objects, attaching components, using an asset provider, and developing smoothly. I sincerely ask for advice, as I'm still far from being a Unity expert.

[knotty sun]

yes, you can install GitHub Desktop which should do the trick, although this looks like a samples package so you might just want to continue

[deft dagger]

oh ill just press continue then

[sonic swan]

When I am lerping my gameobjects transform when using time.deltatime as t myobject flickers really fast from a and b

Why is this happening?

[knotty sun]

because that is not the way Lerp works

[sonic swan]

Wdym like I have a which is objects starting position b which is final position and t when it's set as time.delta time it's flickers really fast

[knotty sun]

t should vary from 0 to 1. deltatime does not do that

[sonic swan]

Oh yeaaa

But there are many scripts that use that and it works

I did it yesterday for a object and it seemed fine

[knotty sun]

bet, they may kinda work but I can guarantee you they do not actually work

[sonic swan]

I got it

Time .delta time only works

If a is the current player pos

It's not a good solution

Cuz u can just use smoothstep

And get a more accurate result

[knotty sun]

yep and even then it doesn't actually work because end pos is never reached

[sonic swan]

Yeye

So imma just use smoothstep

[lean sail]

i dont think smoothstep is what you want either if you're using deltaTime as the 3rd parameter

there is Vector3.MoveTowards, the 3rd parameter takes in a max distance to move which sounds more like what you want

[knotty sun]

@lean sail Remind me, is this a Brackeys screw up ?

[gusty aurora]

Is it not possible to inherit from Component instead of MonoBehaviour ?! I'm pretty it used to be a thing

[lean sail]

honestly not sure, ive barely seen his stuff.

[knotty sun]

I've seen this misuse of Lerp so many times, it must be coming from some popular bloody awful tutorial

[lean sail]

from an old post https://discussions.unity.com/t/there-are-some-big-issues-with-unitys-lerp-tutorial-who-can-i-talk-to-about-it/563742 it seems like unity had it in a tutorial at one point. im guessing if brackeys or other modern day youtubers are doing it, they're all just copying off each other. In which case someone first copied it from a bad example

[knotty sun]

jfc, that's from 9 years ago, I despair

[lean sail]

is there something you're trying to do specifically by having it derive from component instead of monobehaviour?

[soft shard]

I am very confused why a materials list refuses to update but a single material does - if I do someRenderer.materal = something; that works fine in changing the first element to "something" - if I do for(int i = 0; i < someRenderer.materials.Length; i++) {someRenderer.materials[i] = something; Debug.Log(someRenderer.materials[i]);} that doesnt change any element to "something", and since .materials creates instances, I also tried using .sharedMaterials which gave the same result and I dont understand why, maybe its too early here, am I missing something? Do I have to do some kind of renderer.ForceUpdate or something? Why does changing the first element with .material work and not the list with .materials? Nothing else affects this renderer (these are also standard HDRP materials, so no custom shader logic involved)

[gusty aurora]

A script that doesn't use any of the Unity callbacks. It's literally just a component, doesn't need any Update etc

[thick terrace]

the materials property returns a copy of the array, you need to update that element in the array and reassign it back to materials

if you're doing this frequently, you can use GetMaterials and SetMaterials to avoid the allocations from copying

[soft shard]

Ah, alright that confused me, I thought I could update the materials list directly from a renderer reference - thanks for the info on that

[lean sail]

then just make a class that doesnt implement any of the methods. I dont know if you could do what you want awhile ago, but iirc Component is just used for unity's built in components like Rigidbody uses it

[gilded crystal]

Is it possible to make one animator update before another without manually ticking it? I'm considering playable API but not sure if it's feasible

Hi, I have a weird issue, when I initialize the IAP for googleplay I get this error:

Hello, I'm running into an issue where my system file watcher is not successfully executing asynchronous event for loading objects. Any help would be appreciated ((:

[leaden ice]

You're accessing/creating unity objects on a background thread

You did

new GameObject();``` and ```gameObject.transform``` in a background thread. Neither of those are ok.

[thick terrace]

is the Created event on a FileSystemWatcher always called from a background thread?

i guess in that case you could put in an await Awaitable.MainThreadAsync() at the top of LoadObject

[void tendon]

ok thank you. makes sense - I will try that!

[deft dagger]

should i just press yes ?

[void tendon]

no luck! any other idea how I could go about doing this?

[thick terrace]

do you get an error or anything? how do you know it's not working?

[void tendon]

the function doesnt run

[thick terrace]

which one?

and how can you tell it doesn't run 🤔

[void tendon]

Sorry, I have a debug message at the top of LoadObject, which doesnt get called, even after adding the Awaitable.MainThreadSync()

[thick terrace]

and is the one in OnCreated being logged?

[void tendon]

yes, the oncreated is being logged, and it is called

[glad sentinel]

I want to make a 2d game with a fairly advanced movement system and I'm wondering about the benefits of an Event-based Manager or Action Queueing over a State Machine, I havent used Action Queueing before

[void tendon]

Oh nevermind, there was an issue on my end. Working now, thank you so much!!!

[thick terrace]

aha, nice, i was about to say it didn't make sense that you were getting one and not the other 😄

[void tendon]

just so I understand it correctly, what is the Awaitable function doing?

[thick terrace]

it's a Unity helper for doing exactly this, when you await it'll resume execution afterwards at the next Unity async update, so usually on the next frame somewhere between Update and LateUpdate

on the Unity thread, of course!

Awaitable is unity's own version of Task fwiw, there's various other useful helpers in there

[void tendon]

ah ok. I'm only learning about threading over the past week ..confuses me slightly! and so, the reason it doesnt work without that call is because OnCreated is synchronous, and doesnt await my function?

[thick terrace]

no, it's just that OnCreated is being called from a thread other than the Unity thread in the first place, i assume because that's how FileSystemWatcher works (i've never used it)

[void tendon]

oh yes, its a background thread - okay makes perfect sense

[lusty zephyr]

So, I'm making an inventory system and I was wondering how you'd keep track of the items on which spot. Currently, I'm using a list with all the items (item on listnumber 3 stands for spot 3 in the hotbar).

But if you remove an item, all spot change. What should be the best way to keep track of the position instead of a list?

[sleek radish]

Assign item as a children of the slot it in?

[lusty zephyr]

Ah, referring to the slot itself. thanks!

Why didn't I thought of that.

[lusty zephyr]

What if I add an entire inventory with example 30 extra slots. Wouldn't it be bad if I have 30 same scripts in my game?

[sleek radish]

Why would it be?

[lusty zephyr]

I don't know. It feels kinda wrong having 30 same things running the same time. I'm probably just overthinking it. I thought it'd take a lot memory

[terse torrent]

why does Debug.Log() not show up in the unity console?

;-;

[leaden ice]

It does

Maybe your code simply isn't running

[terse torrent]

for me it doesn't, for some reason

[terse torrent]

well

I have a collision code

[leaden ice]

It's not running

You did something wrong in your setup

[leaden ice]

That's not a real Unity function

You made that up

[terse torrent]

wat

[leaden ice]

Check your spelling

[terse torrent]

I mean I am following an 7 year old tutorial but ig you are right

[leaden ice]

You spelled it wrong

The age of the tutorial isn't relevant

[terse torrent]

what did I spell wrong? could you specify more?

[leaden ice]

Also your log is inside an if statement so even if you fix that it might still not run if the condition isn't satisfied

[leaden ice]

The name of the function, as I mentioned

OnCollisionEntered is not a Unity message

[terse torrent]

oh yeaa

sorry

its OnCollisionEnter

thanks a lot!

[terse torrent]

yea I do want that

[leaden ice]

Sure but it makes things harder for you to debug

[terse torrent]

how does it make it hard? I want to know when the object collides with the obstacle, so should I not use an if statement?

[knotty sun]

and what do you do when nothing get's debugged?

[terse torrent]

that means that my player ain't colliding

[knotty sun]

no it doesn't

[terse torrent]

wat ;-;

I think I should go to code beginner...

Hey guys, I've been developing a VR based Squash game and facing some issues in collision between the Racket and the tennis ball, I've tried to write the script for both of these dynamic objects but something is still felt missing, I am dropping both of the scripts below, kindly help..

[amber mauve]

Hi guys, i am building a linux build using IL2CPP on my Mac (silicon chip) for a dedicated server, and it's taking forever on the Linking GameAssembly.so (x64). Is it normal ?

[main oxide]

hi

[haughty belfry]

yes it normally takes a long time building projects with IL2CPP because it converts C# code to C++ before compiling, which takes a lot of time. Also the GameAssembly.so file is pretty large and complex binary, so linking that will also take alot of time.

but you can speed it up for example: by using burst compilers and incremental builds

actually unity uses incremental build pipeline by default for release and development build

[amber mauve]

ok thank you

[trail stream]

any fix for this ?? i get this random blue area that covers a part of the map in game view for some reason

How come my method isn't appearing in the button function, when the method is a public void? https://gdl.space/pahaloweta.cs (RotateObjectAt is the method I am attemptig to call)

[leaden ice]

which method

RotateObjectAt?

[molten isle]

Yes

[leaden ice]

It's because it has two parameters

UnityEvent only supports a single parameter for the inspector

[molten isle]

interesting, so my only fix is to remove one of those parameters?

[leaden ice]

Or remove both parameters

You could separately serialize the parameters as fields

and just have a wrapper function without parameters to call this function with your field values

Yeah that should work

Hey guys! I'm making a metroidvania and I'm having some trouble figuring out how to program the abilities. I don't know what's the best and most modular way to implement them. Can anyone help?

[rich ice]

What is a good way I can find other beginners to work with :D ?

[little meadow]

Unless you have multiple characters with multiple abilites - you probably don't need the best and most modular way to implement them 🙂
But other than that... I guess separate each ability to a separate component and make a prefab with it, and make it so that you can add any of these prefabs to the player and they'll do stuff on top of the core player components (you'll pass components and stuff around when initializing the abilities)

But my personal approach to anything that I can't imagine how to make nicely is... just make it work and see when it starts being annoying to work with and refactor until it's good 🙂

[nimble eagle]

In the game I want the player to have 2 ways of combat. The main way is through a melee attack. The second way is through a revolver which is charged by hitting the enemies with the melee attack. Down the road I intend to add more abilities such as dashing, a charged melee and revolver attack, etc. For now I have a player controller which handles only the input, a player movement, a revolver script and a melee attack script

[frosty trench]

Nobody knows what might be causing this?

[fleet gorge]

first guess: use an unlit material for the background video

your video player renders to a render texture, which is assigned to a material. change this material to be an unlit one

[frosty trench]

let me check this!

[soft shard]

Are you looking for feedback or just sharing your approach? Its a bit unclear to me if there is a question here

[frosty trench]

im not quite sure where to change that material, honestly i dont see any material section in the inspector

[fleet gorge]

Is it rendering in world space or UI space?

[nimble eagle]

I'm sorry, I don't like my implementation so far and I'm not sure what other way I could implement abilities

[fleet gorge]

I'll need to look into how the video player works again

[frosty trench]

Layer is default so i guess world?

But my previous background image was also on default layer and the glow was working

[soft shard]

Ah, I see- maybe you could look into FSM (Finite State Machine) and implement a similar pattern with "states" or "sub controllers" for your input and abilities these states/sub-controllers can also use [System.Serializable] so you an edit them in the inspector and dont need to derive from MonoBehaviour - or you could look into interfaces with abstraction and generic classes, which would be a more code solution that wouldnt use the inspector, the abilities themselves could be inherited classes or possibly a list of ScriptableObjects that 1 mono script initializes/updates - if your using the "new" input system, you could also subscribe events for input to have certain keys call certain ability indexes, I do something similar for a "hotbar" in one of my games

[nimble eagle]

I'm thinking about making a monobehaviour script attached on the player that holds all of the abilities which are SOs

So basically a list of SOs that derive from a base class

[fleet gorge]

you dont have to hold all the abilities, hold the current one

swap out when needed

if you place your SOs in the Resources folder you can Resources.LoadAll

[nimble eagle]

But what if I have a revolver, a dash, a double jump, etc?

[fleet gorge]

how many abilities can the player equip at once

[nimble eagle]

No idea, since it's a metroidvania, the player will gradually unlock more abilities as they progress through the game

So all of them basically

[fleet gorge]

ohh

yea then have a List of SOs

[nimble eagle]

Should I use a map instead of a list?

Would be easier to call each SO ability from the player controller I think

[fleet gorge]

that's hardcoding ❌

the base SO will have different functions you can override like OnJump, OnShoot, OnMove etc

you can call the according functions in the player controller but don't hardcode it

[nimble eagle]

I was thinking the base SO would have a function TriggerAbility and each derived class implements it differently

And the player controller would call that function depending on the key pressed

For example OnShoot would be something like: abilityHolder.UseAbility("RevolverAbility")

And UseAbility triggers the function of the specified SO

(If I would use a map)

[lean sail]

Anything string based like this will be a pain in the ass

[nimble eagle]

Idk man, I'm not too good when it comes to system architecture

[fleet gorge]

you can use System.Action, it's like a list of functions.

System.Action onDeath;
public void deathEffect() {}
...
onDeath += deathEffect;

calling onDeath.Invoke calls deathEffect

you can add many functions to one System.Action

[knotty sun]

hmmm, no

[nimble eagle]

Please Steve

Make me understand this ability system thing

How would you do it?

[knotty sun]

Your SO approach is not bad, but replace the strings with enums

[nimble eagle]

Oh

I see what you mean

But how would I call a specific ability from the player controller?

abilityHolder.TriggerAbility(???)

I mean how do I pass an enum state to the function

[knotty sun]

say you have an enum

public enum Ability {
  RevolverAbility,
  // More here
 }

then

abilityHolder.TriggerAbility(Ability.RevolverAbility);

[nimble eagle]

Is the enum in the player controller?

[knotty sun]

and the method signature is

public void TriggerAbility(Ability ability) { }

[knotty sun]

enums are a type, they can be anywhere

[nimble eagle]

So its in both scripts right?

[knotty sun]

no, generally I put public enums all in their own script

[nimble eagle]

Ah, I didnt know I can do that

[knotty sun]

basic C#

[nimble eagle]

Would the ability holder still use a map?

Or just a list?

[knotty sun]

Either is good, whatever is easiest for you

[fleet gorge]

a map is just faster

[nimble eagle]

Which would you personally choose?

[leaden ice]

Dictionary is so much simpler if this is the use case I think it is

[nimble eagle]

I think a map is better cause its easier to work with strings than with index

[leaden ice]

well they'd be using their enum not a string

[fleet gorge]

dictionaries/maps work like arrays

[nimble eagle]

Yeah you get my point xd

[fleet gorge]

in fact for c++ we just use enums for arrays

[knotty sun]

I would use an array, but I'm a stickler for performance. A Dictionary is probably easiest for you to implement without problems

[nimble eagle]

Okayy

Thanks for your assistance

Btw are dictionaries serializable?

[knotty sun]

no

[leaden ice]

not out of the box by unity*

[nimble eagle]

And I would need them to be right?

[cold parrot]

you can easily serialize them manually

[knotty sun]

there is an easy workaround using the ISerializableCallback interface

[little meadow]

I have to say, I highly dislike those enums that tend to grow indefinitely over time... I'd rather use const strings (or not strings, but strings are "easy")

[leaden ice]

that depends on what you're doing.

[nimble eagle]

What if I just load all the abilities from the project files into the dictionary and assign each key as the SO file name?

[knotty sun]

yeah, and when you profile your game because the FPS is shite, the first thing you need to do is remove/replace those strings

[little meadow]

only if you're using them a frogload per frame... 🤷‍♂️
has never practically happened to me even on mobile dev... but if performance is a problem - yes, you'd replace them with something better... still not an enum, because an enum like that binds things together (things that are unrelated, to a large degree)

[lean sail]

It's not like const strings are gonna be used differently or are more performant. This would just make it a pain to assign in inspector if needed

[chilly surge]

The performance impact of using const strings is probably minimal and insignificant, because they are interned. That said, you should still use something else rather than strings for other more important reasons.

[leaden ice]

Isn't this basically equivalent to an enum in most important ways?

[little meadow]

You don't have to stick them together. Adding a new implementation of the thing no longer requires adding something to an enum, and in a sense changing existing code.
Perhaps I'm biased, as I've seen these enums go out of hand way more than I'd like... 😦 At some point people add switches and if's over them and suddenly when you add a new thing, you need to find all usages of the enum and adjust that code as well.

Enums just make it very easy to feel like it's an exhaustive well-defined list of things

[chilly surge]

when you add a new thing, you need to find all usages of the enum and adjust that code as well.
There are diagnostics for that.

If you use strings, there's truly nothing that can help you, unlike enums.

[little meadow]

That's partially fair, but the thing is, you're less likely to mess it up like that, as you wouldn't have the same expectations as with an enum

(I'm not a fan of random strings, let me clarify that... but if they're consts and not eating performance... 🤷‍♂️ )

[leaden ice]

Any sensible defensive programmer is doing this:

switch (thing) {
  case A:
  case B:
  default:
    throw new Exception($"Unrecognized case encountered: {thing}");
}```

[knotty sun]

And, of course you conveniently over look the fact that a string takes up 2 bytes per character whereas you can store 256 enum variations in 1 byte

[chilly surge]

IDE0010 and IDE0072 will emit warning when you modify an enum and the switch no longer handles all the cases. You can turn that into a compiler warning (bonus point for turning on warning as error) to actually enforce the problem you are talking about.
If you use strings, there's truly nothing that can help you.

does anyone know y my sphere overlap isnt detecting any colliders in the scene

[little meadow]

Again, memory is the cheapest thing nowadays, you're extremely unlikely to eat a reasonably amount of it by having 1000-2000 strings 🤷‍♂️ premature optimization and all that

[leaden ice]

please follow the instructions from the bot

[mossy ermine]

im trying xd

[leaden ice]

You can literally copy and paste this part

[little meadow]

This is a problem, because this code now needs to be adjusted, and is even worse than what Burrito is suggesting, because at least with Burrito's approach you'll get a compiler error (right?), and with this you'll get extra sad at random runtime

[mossy ermine]

ye mb i though it was just to add cs lol

[leaden ice]

Using strings doesn't save you from actually having to implement code that handles a new case being added

[little meadow]

It pushes you away from thinking this code is a good idea in the first place

Because it makes it less convenient / even more weird to write it in the first place

[chilly surge]

Strings are interned, you can have 1000 occurrences of "foobar" in your source code and there will only be one copy of it at runtime, and comparison of them will be just as fast as comparing two objects because it's just comparing two addresses.
I think the performance impact of string vs enum should not be the center of this conversation, but rather all the organizational issues and the fact that they are practically reinventing a language feature in their own unsupported way and thus missing out all the existing tooling benefits (like the diagnostics).

[little meadow]

enums are great for days of the week or months or anything that's well defined and won't be changing all the time

[mossy ermine]

does anybody know?

[leaden ice]

I guess I'm trying to understand what this alternative you're suggesting is that's somehow better

And what's so bad about an exception

[chilly surge]

It's 100% not better, it has the exact same issues as enum but more.

[leaden ice]

exceptions are excellent

they give us visibility into our errors

[chilly surge]

If you add a new const string, it's not any better than adding a new enum member.

Except you get no help from diagnostics to tell you to update your existing code.

[leaden ice]

imagine if instead of an exception you just left out the default case in your switch. Now we just silently fail instead of loudly failing

and our bug goes undetected for weeks

[little meadow]

no, no, exceptions are great, I'm saying that compiler warnings and errors are better, as those can help you even earlier in the dev cycle

and fine, I'll agree, probably strings aren't better

just pass instances or something around

the point is to not need a list of all things that are kinda unrelated... like all abilities... you shouldn't need one place that knows about them all and does stuff with them

[wide terrace]

Have you verified that your OnCollisionEnter() method is executing, and debug-drawn the sphere or flipped on the Physics Debugger's query drawing to ensure that the sphere is where you expect, and does indeed overlap with non-trigger colliders?

[midnight cypress]

Hey everyone. Is there a way to set a texture.jpg to a material as the Base Map in a script?

[little meadow]

and that's what an enum like that is... a place that knows about all of them... then people start using it as such, then adding new ones becomes a problem

[mossy ermine]

the on collision enter works but how would i debug to see where the sphere is

[midnight cypress]

It seems I can set the normal map image just fine, but for some reason I can't figure out how to set the base map image

[wide terrace]

Window > Analysis > Physics Debugger > Queries

[chilly surge]

It really is not if you have compiler helping you whenever a new variant is added.

[deep oyster]

So I'm using a buoyancy effector2D on a water object that's using a polygon collider. If my character floats over a quad edge in the water, they get effected by twice the buoyancy and float in place. It seems like there might be no way to avoid this?

[chilly surge]

Enum represents an exhaustive list of possibilities (kind of, C# enum doesn't exactly but that's besides the point), if you have compiler to help you ensure that exhaustiveness, then you are good to go.

[little meadow]

it won't help you if you have a default case or if you just have a weird if that now needs to be adjusted

[chilly surge]

Nope

The diagnostics ensure you must handle all cases

[mossy ermine]

the sphere is where its supposed to be

[chilly surge]

The diagnostic will still warn you for trying to use default case to ignore everything else.

[little meadow]

Ah, okay, so then you can't use default, which is a problem in some of these places... or again, you just used an if to check if it's 3 of those now 26 enums

and now there's a 27th... what do you do? find all instances, think of what was the intended behaviour in each place, get sad, spend time, etc...

if they have different behaviours and you're constantly adding new ones, then you should have proper objects that you're passing around, with properties and whatnot

and then you don't need one place with all the IDs (the enum)

[chilly surge]

You absolutely can use default, in fact, you must use default.

[wide terrace]

And there are Game Objects with non-trigger colliders within/touching it? What is your Debug.Log(colliders) logging?

[mossy ermine]

empty

its not getting any of the colliders for some reason

[chilly surge]

I suggest you to take a look at the links of those diagnostics, if you have an enum:

enum E
{
    Foo,
    Bar,
    Baz,
}

The rules will enforce you to write code like:

switch (e)
{
    case E.Foo:
        DoFooStuffs();
        break;

    case E.Bar:
        DoBarStuffs();
        break;

    case E.Baz:
    default:
        DoDefaultStuffs();
        break;
}

When you add a new variant to the enum, you are forced to also add a new case (even if you are going to just ignore it and let it handled by default), forcing you to acknowledge it.
You are also forced to always have a default case.

[mossy ermine]

any idea y this is happening @wide terrace

[little meadow]

I see, I see... so it'll get a bit verbose? It is a cool feature that I did not know about 👍 ... but I'm saying those just shouldn't be enums in the first place. Logic should be inside some object implementation and not in a place that knows about ALL things that you're changing all the time.
Open-closed principle or something, right?

[leaden ice]

Well this is arguing for object oriented programming basically

And polymorphism

Which has its place but also its own drawbacks

[wide terrace]

Hmmm... the code looks fine to me. And layers shouldn't be a problem since it defaults to all layers. I'm not really sure :/

I'll try to make a small replication really quickly, just to see if I'm not overlooking something obvious. But hopefully someone else might have a better idea

[mossy ermine]

alr thanks for the help

[chilly surge]

Polymorphism also requires you to put the handling code on the object itself, which is problematic in its own rights.

[little meadow]

Same as enums - they're great for stuff that's very localized and/or constant, very annoying if you need to modify it every time you want a new implementation of something

[chilly surge]

You are essentially pointing out the expression problem: https://en.wikipedia.org/wiki/Expression_problem

In object oriented code, adding a new variant is easy, just add that new class; but adding a new operation is hard, you need to now modify every single class.
In functional code, adding a new operation is easy, just add that new operation and switch on it; but adding a new variant is hard, you need to now modify every operation's switch.

They both have their problems, you might be only seeing half of the expression problem, the half that favors OOP.

[wide terrace]

Change your Debug.Log(colliders); to like Debug.Log(colliders.Length);, just to be sure - it looks like colliders do not serialize into a string, so logging the array may be misleading

[mossy ermine]

ok

ya ur right now it shows 4 colliders

[wide terrace]

I guess the next thing to check is if your game objects with the colliders have a rigidbody (on that very same GO - not on a child/sibling/parent etc)

[mossy ermine]

ya they have rigid bodys

how do i change to make it look for things in a specific layer cuz i have a feeling that might fix it

@wide terrace do yk how?

[little meadow]

thanks @chilly surge didn't think of it that way and didn't know about the expression problem...
still, the use-case was specifically about an enum of IDs for SOs that define abilities... that's bound to grow whenever they want to add/experiment with a new ability, plus they already have an object that they can work with 🤷‍♂️ not using said object and doing any magical ifs/switches on IDs is making the system way more annoying to extend, wouldn't you agree? because now the logic is all over the place, outside of the object/class that defines the ability

[wide terrace]

Add a LayerMask field and pass it into the OverlapSphere() call as the respective argument - it'll let you select the the layers in the inspector through a nice interface.

I'm sort of skeptical that it could be the layers, but it's worth a try. You might also throw some logs in to check if the rbs are null, and maybe use a much larger force and/or ForceMode.Impulse, particularly if these rbs have some amount of mass

[wide terrace]

Maybe share a screenshot of the inspector for one of the objects that the explosion should be affecting - particularly the rigidbody component

[mossy ermine]

it keeps giving me an error when i try to have a debug message give me the rigid bodies saying cannor acess floor rb cuz it doesnt have an rb

this is the player

[wide terrace]

Are you directly controlling position or velocity in PlayerMovement?

[mossy ermine]

velocity

but the layermask thing worked

i still dont get y it wasnt working without it

[wide terrace]

I do not know... I would like to understand as well 🤔

[chilly surge]

That very much depends on how you are going to use the abilities. If an ability is only ever going to be used one way (so there will never be a new operation), then sure.
However imagine a different scenario: an ability simply contains some metadata about the ability (cooldown, how much damage it deals, mana cost, etc), but different game modes may handle the ability differently. Perhaps not even game modes, you want to transmit "player A casted ability X" across network. Now what do you do, do you put every game mode's handling code into ability classes? Do you also put the network handling code into ability classes too? Why should ability classes even need to know the fact that this game has different game modes or that it's a networked game? Now you just run into the opposite problem: ability classes suddenly need to know the every possible way an ability is going to be used in the context of the entire game.

It circles back to the expression problem again, if you go the OOP route, adding a new ability is easy, but adding a new game mode is hard; if you go the functional route, adding a new game mode is easy, but adding a new ability is hard.

[little meadow]

sure, but the original request was "how to add more abilities easy" 🤷‍♂️

it's a decent example (well, a bit extreme), but you'd probably still not use enums and switches, you'd need a more complex approach to do game modes that affect abilities in a good way, and would depend on the specific needs for said game modes

[chilly surge]

Yes, and there are solutions to the expression problem for both directions.

The point is, there's no one simple answer to picking which approach and either comes with its own downsides. If you completely ignore the problem of adding new operations later on, then the OO approach will make adding abilities very easy, but you better hope you aren't going to add more operations later on.

The moment you need to add a new operation, your 50 ability classes will all be red and your project will not compile until you modify those 50 different files.

[little meadow]

I completely agree with no one simple answer... 👍 I'm just saying that if you have an enum that will have more and more values (variants) by definition, that already means you need to use something that handles variants well 🤷‍♂️ If you also need to handle adding more functions easily - that's another thing to consider on top of the first

hi, why does the enemy not get hit when the sword is close to it, but it gets hit when the sword is distanced slightly further away, and how would I fix this? thanks

[leaden ice]

OnTriggerEnter is really not a great way to detect attack hits like this

you should use direct physics queries

e.g. Physics.OverlapBox

[sly chasm]

[slow plover]

I'm trying to draw a bunch of instanced meshes to a secondary camera, but not to the main camera. The secondary camera is copied from the main camera, I set the DrawMeshInstancedIndirect call to use camera: secondaryCamera, which the documentation says should only draw to that camera, but the main camera is still drawing them. I must be missing something, anybody have clues on where I could look?

[leaden ice]

you sure your camera reference is set properly?

The docs say:

If null (default), the mesh will be drawn in all cameras

[slow plover]

Yep, it's strange. Looking through the frame debugger and it seems like both cameras are rendering to the main render texture. I'll play around with changing that.

[leaden ice]

well that would certainly do it

[hidden compass]

Can't see that on mobile btw

[leaden ice]

well first off the first two lines where you try to set it (the stuff related to LeftControl) will be overwritten by the second two lines where you do

so effectively only the if (Input.GetKey(KeyCode.LeftShift) && canSprint) part matters

theoretically you should be toggling between 30 and 35 degree fov due to that code

which isn't that much of a difference

I am looking for some pointers in the right direction on how to set an external display (display 2 for simplicity) and be able to change it's resolution at runtime.

[tender gull]

hey, can you clear for me few things about cameras? I'm using Unity 2022.3 with URP 14.0.11 and can't force my cameras to work...
firstly - I'd like to have separate cam for UI, so I have my UI camera on UI layout with UI as only layer culling and it's set to overlay.. next I have main camera as base and added UI camera stacked there... next I have canvas with image on UI layer (canvas and all it's children). Canvas is set as screen space - overlay.

So is it correct that both main and UI cam can't see it at all (preview in scene panel are empty), but still in game view canvas with image is visible? The problem is reversed if I turn canvas rendering to screen space - camera and select UI cam - UI then isn't visible anywhere (playing with distance didn't change a thing).

[flat marsh]

Hi guys I am having an issue where I cant access the variables of the child object from the parent object. Would someone please be able to help me? Here's the code https://gdl.space/qawatacawo.cs, and some screenshots of the inspector in case that helps:

[knotty sun]

floorCheck should not be of Type GameObject. It should be of Type Ground_check_script

[tender gull]

hey, can you clear for me few things

another problem is rendering to texture and than showing it with alpha channel... so:
I have camera rendering to the texture with bg set to black, no alpha (0, 0, 0, 0) with culling mask to catch an object.. it seems to work well - I got only that object in texture and image in preview looks as it should..
Now I add it to the canvas UI as an Raw Image and it starts to be strange - my rendered image looks like it has about 50% opacity... whole image - there is no alpha and I can't even make it to show as solid (color for image is white with full alpha).

[flat marsh]

Oh my gosh, tysm I had no idea what was causing it. TYSM!

[knotty sun]

dont forget to reassign it in the inspector, when you change the type of a variable it will show Type Mismatch in the inspector

[flat marsh]

yeah I did that :). TYSM again

[sonic swan]

you know how you have mathf.smoothstep for smootly interpolating what tyoe of thing is there for exponentioal interpolatioinb

nvm i used animation curve and it looks worse that smoothstep

[leaden ice]

You can simply use Mathf.Lerp and apply any easing function you want.
e.g.

t += Time.deltaTime;
float eased = MyEasingFunction(t);
var result = Mathf.Lerp(start, end, eased);```
You can also use an animation curve as you mentioned:

```cs
t += Time.deltaTime;
float eased = myAnimationCurve.Evaluate(t);
var result = Mathf.Lerp(start, end, eased);```

how can i make the bullet shoot in the direction that is calculated? that line that says wrong code, its a theory that doesnt work... so its wrong

[leaden ice]

that code is correct for shooting the bullet in the direction specified as direction

perhaps you are calculating the wrong direction

[steady oasis]

its giving errors

[leaden ice]

what errors

maybe start with that

[haughty belfry]

normalize the direction vector

[leaden ice]

you can't just have errors and not tell us lmao.

[leaden ice]

this is true and a good idea, but not the main problem

[steady oasis]

its in the editor.

[leaden ice]

I can't see your editor sir

[steady oasis]

sorry, my bad

[leaden ice]

delete using System.Numerics from the top of your script. There's no reason you should have it there

[steady oasis]

it was default

[leaden ice]

and yes you should do direction.Normalize(); right after that

[steady oasis]

what is that? can you explain in nutshel?

[leaden ice]

it normalizes the vector

[steady oasis]

oh so it normalizes all the things

[haughty belfry]

add this Vector2 normalizedDirection = direction.normalized; and then apply the force based on the normalized direction

[steady oasis]

ohki thanks

[haughty belfry]

actually you can just normalize the direction vector directly without creating the normalizedDirection so that is also correct

[ashen oyster]

Is there a way to send a rendertexture to a material without blitting? I tried

_material.SetTexture("_PrevFrame", _prevFrameHandle.rt);

and then using a sampler2D in the shader

sampler2D _PrevFrame;

To no success

Maybe important, I'm putting this in the execute function of a render pass

[stable osprey]

is there a reason you'd like to avoid blitting?

[ashen oyster]

Yes, I need two render textures in one shader

[stable osprey]

and why is blitting preventing you to do that?

public static RenderTexture Copy(this RenderTexture rt) {
    var newRT = new RenderTexture(rt);
    Graphics.Blit(rt, newRT);
    return newRT;
}

[ashen oyster]

Since if you blit you can only access the one variable you have acces to, _BlitTexture no? also, blitting executes a render pass

Blit(cmd, cameraTargetHandle, _rtHandle, _accumulateMaterial, 0);
Blit(cmd, _rtHandle, cameraTargetHandle);

Here's my HLSL:

    HLSLINCLUDE
    
        // The Blit.hlsl file provides the vertex shader (Vert),
        // the input structure (Attributes), and the output structure (Varyings)
        #include "Packages/com.unity.render-pipelines.universal/ShaderLibrary/Core.hlsl"
        #include "Packages/com.unity.render-pipelines.core/Runtime/Utilities/Blit.hlsl"

        sampler2D _PrevFrame;
        float _Frame;
        
        float4 _BlitTexture_TexelSize;
        
        float4 frag (Varyings input) : SV_Target
        {
            float4 col = SAMPLE_TEXTURE2D(_BlitTexture, sampler_LinearClamp, input.texcoord);
            float4 colPrev = tex2D(_PrevFrame, input.texcoord);

            float weight = 1.0 / (_Frame + 1);
            float4 accumulatedCol = saturate(colPrev * (1 - weight) + col * weight);

            return accumulatedCol;
        }
        
    ENDHLSL

[stable osprey]

calls to Graphics (or other GPU APIs) don't execute anything synchronously anyway

they asynchronously queue stuff to a buffer which gets awaited on the next sync call

yeah the issue is you're blitting to the RT you would like to keep intact. Using the Copy method I posted above should do it!

[ashen oyster]

Should do what exactly? make a copy of the render texture? Now how do I send that to the shader?

[stable osprey]

_material.SetTexture("_PrevFrame", RTUtils.Copy(_prevFrameHandle.rt));

RTs are still references, so if you pass the RT before it changes, the changed version will be used by the shader (-- when it does)

sry I was in the middle of grabbing coffee so excuse my low effort english xD

@ashen oyster did that work?

[ashen oyster]

Er no, give me a second, maybe you're more eagle eyed than me

Here's the execute script, I put comments on the places to explain what's happening

I just get a black screen

Yes I could've used code blocks but discord's syntax highlighting is abysmal

returning just col works fine btw, that samples the blitted texture

[stable osprey]

you seem to have 4 extra blits there -- are you sure they're correct?

[ashen oyster]

How do you mean?

[stable osprey]

anyway.. the issue is you're using SetGlobalTexture but _PrevFrame is not market as static (uniform in shaders)

why not material.SetTexture?

[stable osprey]

I'm talking about the accumulation stuff -- I don't really get what they're supposed to be doing lol -- just making sure you do

[ashen oyster]

Ok weird, that's what I tried first but didn't work so I tried gobaltexture instead. Now that I switch back it works 😵

[stable osprey]

maybe you didn't explicitly press ctrl+R after your shader change -- which is needed to apply shader changes

(actually not sure about newer versions -- it is the thing I have to do in older version tho)

[ashen oyster]

I'm pretty sure unity HMR that just fine since I've not needed to do that

[stable osprey]

well great that it works now then ^^

[ashen oyster]

Ah yeah, they are absolutely necessary lol. They're the reason shader passes get executed at all

[stable osprey]

I have been avoiding URP/HDRP because I wanna avoid this kind of necessary magic lol.. the standard RP is just fine 😆

[ashen oyster]

lmao, not for my usecases xD

[stable osprey]

pretty sure everything's a notch easier programming-wise without URP/HDRP lol

[ashen oyster]

Yeah sure but then you're doing post processing with monobehaviors which is silly imo xd

I'm a fan of these SRP injections

(even though it's a massive struggle to find any good documentation on it)

[stable osprey]

well the SRP just changes the standard Update() to a specialized Execute and provides a premade and not-fully-customizable command buffer afaik -- not much of a bonus imo xD

yeah sure it can be nice in that sense -- but organization-wise a nicely named script (e.g.: Shaders/Magic/PostProcessing/FadePostProcessing.cs) might be as good

[ashen oyster]

It comes down to "whatever works best" ig :P

[stable osprey]

also it doesn't have to be a MonoBehaviour if you've gone through the trouble of adding a CommandBuffer to your camera. That's actually the best practice (potentially even static method library)

[kindred blaze]

im making a voxel system and i thought i should disable the mesh of a voxel if it is surrounded on all sides by solid voxels for optimization. is it necessary to do this or does the renderer not render them automatically?

[manic pike]

Why would one need [SerializeField] when the field itself is already serialized and readable by the inspector?'

[vestal arch]

you would not

as the Serialization manual says, SerializeField just bypasses a check for the field being public. if it's already public, SerializeField doesn't do anything, as your ide might tell you

[hard estuary]

It's usually used on private fields to make them serializable and visible in the inspector. It's useless for public fields. Some people like to add useless code to make it easier to remember the code's purpose. Writing private before fields is a similar example - useless, yet people keep doing it.

[manic pike]

Fair point; and I apparently did public out of habit instead of private

[stable osprey]

I've established some practices that I like to recommend:

1. When you need it tweakable from the inspector but otherwise immutable, go for private field [SerializeField] MyClass field;
2. When you need it readable from other scripts..
   2a) .. but only settable within the script, go for public MyClass field { get; private set; }
   2b) .. but only settable from the inspector, go for [field: SerializeField] public MyClass field { get; private set; }
3. When you need it only tweakable within the script, go for private field

this way you never really need public fields

[manic pike]

I'm screenshotting this, if that's fine?

[stable osprey]

totally!

[manic pike]

Thanks!

[wind mural]

Hey guys I was trying to test something super basic and encountered a weird case which Im not sure if it existed since forver with Unity?

I have 2 GameObjects in the Scene
Object A with a Script A which has Awake and OnEnable methods just printing logs
Object B with a Script B which has Awake and OnEnable methods just printing logs

When I run this, I get logs as
Object A Awake
Object A OnEnable
Object B Awake
Object B OnEnable

As far as I remember all Awake should be called first and then OnEnable right?

[vagrant blade]

It's per object

But these will all run before any Start methods will run in your scene

[sleek bough]

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

If you need more granularity than Start-Awake you can turn Start into a coroutine and skip frames to guarantee later execution.

[wind mural]

Was it like this since forever?

[wind mural]

Because as far as I remember it should run all Awake first for all loaded objects and then called OnEnable for them

[vagrant blade]

I don't recall a time it was different, no

[wind mural]

Ah okay thanks!

It has always been this way yeah

why cant it detect the bullet?

[simple egret]

Error is on line 55, what's on that line?

(RANGED_manager.cs:55)

[somber nacelle]

i'm going to guess that ObjectPool.instance is null since it is not assigned to anywhere in the code we've been shown

[simple egret]

That is indeed most likely the issue, there is no singleton initialization code in ObjectPool

[steady oasis]

starts from there

[steady oasis]

i added the script to an empty object called PoolManager and referenced the bullet there

[somber nacelle]

that line cannot throw that exception

[somber nacelle]

that does not mean that ObjectPool.instance is not null (hint: it is)

[steady oasis]

then what should i do?

[somber nacelle]

you need to assign to it. you clearly tried copying the singleton pattern without actually understanding what it is. maybe go back and look at where you copied that from and see where the instance variable is assigned

[steady oasis]

i saw a video, and it didnt explain anything like that. imma try what u said

i took it from here https://www.youtube.com/watch?v=YCHJwnmUGDk

[somber nacelle]

yeah you 100% missed the part where they assigned to instance

[steady oasis]

what part is it?

[somber nacelle]

my guy, it is a 4 minute long video. go watch it yourself

[steady oasis]

where they defined ``` public static ObjectPool instance;

[somber nacelle]

please actually pay attention to the video

[steady oasis]

i did

come on, a little hint

[somber nacelle]

then surely you saw where instance was assigned

[steady oasis]

cuz its correct code to code

[somber nacelle]

no it isn't

[steady oasis]

oh ohki found it

sorry

[steady oasis]

after fixing its giving me error on line 55 and 26

https://gdl.space/inuyenivag.cs

that is the whole enemy shooting and moving code

[somber nacelle]

clear your console, make sure your code is actually saved and has compiled, then do whatever it is that causes the errors. because line 55 cannot throw an error

[steady oasis]

oo it was a completely different script that was just a test

forgot to delete it

it showed me the actual script when double clicking at the first time, ig i must have clicked a different message

I am looking at the URP samples. it gives an error in its initial form.

IDK what to do

[knotty sun]

show how you tried to add the namespace

[twilit scaffold]

namespace ShaderSampleShowcase; under the using references

[somber nacelle]

you cannot use file-scoped namespaces in unity. it has to be a block scoped namespace

[twilit scaffold]

Ok thanks, i just put it in {}, but the errors remain (Not the namespace error, the initial one)

[somber nacelle]

well you've got a type with the same name as a namespace. did you put that type into the namespace you created?

or have you considered simply renaming either of them?

[twilit scaffold]

I believe so. the namespace block encompasses everything except the using statements. I attempted to rename samples as the first thing i did, but it says i cannot.

[somber nacelle]

you have to rename it from the class declaration, you cannot rename it from there

[twilit scaffold]

I am having trouble tracing that back. where i thought it was, it is not. i will keep looking. Thanks

[somber nacelle]

wdym? did you not put that class into a namespace?

[twilit scaffold]

I thought i did. I am off to take some c# courses. Thanks for the directives 🙂

[white perch]

Hello, currently I work on a Tycoon and I struggle a bit with inability to choose way to store sprites of each building from blueprints. With my current knowledge I guess that the most optimal solution would be to use the SerializeField attribute but it may be you know better way to do that : pp

[hard estuary]

I'm not sure if I understand your problem correctly.
Adding serialized fields in objects directly makes it easier to configure your assets in the Inspector. The drawback is that sometimes you end up with storing the same information in multiple objects. Usually it doesn't hurt, but it could be a problem if you have thousands of instances of that object. In such cases, it's worth considering if it's possible to store it in some sort of singleton or manager. But in 99% of cases [SerializeField] is good enough.

[somber nacelle]

either put your world space camera there, or you'll need to manually raycast against that object and convert the hit point to a point relative to the canvas

[tender gull]

I'd like to bump poor soul's problem =p

Anyone here good with Quaternions, the following code is for rotating my player but it's a little clunkier than I'd like, I want to know how I can rotate on the Y-axis at a different speed than on the x and z axes. Y axis rotation is for the players movement rotations whereas X and Z are for aligning with the ground normal

if (vector == Vector3.zero)
{
    rb.MoveRotation(Quaternion.Slerp(transform.rotation, lastTargetRotation, rotationSpeed * Time.fixedDeltaTime));
    return;
}

Vector3 forwardDirection = Vector3.ProjectOnPlane(moveVector.normalized, targetNormal);
Vector3 upDirection = targetNormal;
targetRotation = Quaternion.LookRotation(forwardDirection, upDirection);
lastTargetRotation = targetRotation;
var horizontalRotation = Quaternion.Slerp(transform.rotation, targetRotation, rotationSpeed * Time.fixedDeltaTime);

rb.MoveRotation(horizontalRotation);```

[ashen oyster]

Friendly reminder to set your render texture precision higher, I've been debugging for 6 hours only to find i set the descriptor to default instead of ARGBFloat.

All my issues were fixed after that :<

nvm I realized the value was in the editor, not in the script

[open dome]

Hello, i wanna ask a question about AudioClip in Unity.
When i try to GetData() from AudioClip that i load from path using UnityWebRequest it give me error: "Cannot get data on compressed samples for audio clip "". Changing the load type to DecompressOnLoad on the audio clip will fix this." But when i open the file from UnityWebRequest i have enable compress and stream to false. Does anybody know how to fix this?

[stable osprey]

@open dome do you download it from the internet? or load a file from your Assets folder?

[open dome]

I load the audiofile from my local device.

[stable osprey]

hmm it should be plug & play

@open dome why not UnityWebRequestMultimedia.GetAudioClip?

https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequestMultimedia.GetAudioClip.html

getting data isn't necessary before you create an AudioClip out of your downloaded audio

[open dome]

Yes, i already use UnityWebRequestMultimedia.GetAudioClip but it still give me "Cannot get data on compressed samples for audio clip "". Changing the load type to DecompressOnLoad on the audio clip will fix this." Error.

[stable osprey]

audio clip ""?

can you try using var clip = DownloadHandlerAudioClip.GetContent(www); as in the docs?

also you check if it's done but if it's not you just skip -- your function is not very robust for non-local files

GetContent I think is synchronous, so potentially not ideal for online files either, but you'll get around it with isDone similar to how you did (while (!isDone) { yield return null; })

[open dome]

When i change the way to get the content using var clip = DownloadHandlerAudioClip.GetContent(www); its still give me error when trying to GetData() from the clip.

[stable osprey]

but it can play properly if you don't try to GetData, right?

[open dome]

Yes the clip before and after changing the way to get the clip can play properly.
But i still can't use the GetData function from the clip.

I need the clip to be able to use GetData function, since the whisper plugin that i use require the access on that function.

[stable osprey]

I'm wondering whether at some point these are overriden

might wanna try it before GetContent?

also yeah sounds like your previous method should work too but Unity is weird in some cases when it comes to following the docs xD

[stable osprey]

looks like a weird execution order thing by unity's side imo

you might also wanna try waiting a frame or two after the download is done

@open dome or clip.LoadAudioData()

[open dome]

Putting it before GetContent Still giving error

[stable osprey]

surely Unity side bug since GetData should automatically load/decompress it -- but yeah.. dlHandler is instructed to not even compress it in the first place

[open dome]

When i try adding wait for 0.2 second it also still cant use the getdata function

[open dome]

darn

[stable osprey]

this might work

I've had my share of frustrations with unity web requests -- to the point I just went with .NET's HttpClient eventually xD

once I have the MP3 or whatever it's just easy to load it as an AudioFile -- same to transporting it to any other formats

[unique flower]

any unity help

in reblinding the controls in unity

manCry

[stable osprey]

it worked!? I knew it!

[open dome]

Hmm... where should i put this function?
When i Debug.Logging the function it return True. But still can't use the GetData function from audioclip

[open dome]

nope :<

[stable osprey]

damnnnnnnnnnn

sadly I'm out of insight on how to do it with code lol...

[stable osprey]

the 0.2sec should be done AFTER GetContent

also, the BUT was to change a setting in preferences, but seems it doesn't exist 😛

insert the wait right above GetData

also, mind that GetContent is kind of synchronous and indeed expects dlHandler to be done

more robust is while (!www.downloadHandler.isDone) { yield return null; } (wait until it's done before proceeding with using the downloaded file)

[open dome]

Still giving error when trying to GetData from clip after waiting.

[stable osprey]

go with different plugin, then, imo 😛

If you're willing to run your own local whisper model (assuming you already do), could take a look at LlamaSharp
-- I've made an example for Whisper integration with it as well: https://github.com/SciSharp/LLamaSharp/pull/656

it's for speech-chat so it might look a little complex but the transcription part is much easier -- and it can serve as a server as well

(sorry I can't help with the actual issue you're having 😛 I've exhausted all my ideas -- maybe someone else has more)

[open dome]

Its ok, thanks for the help.

[stable osprey]

oh I meant to link whisper.net btw: https://github.com/sandrohanea/whisper.net -- but the code should be the same as the LLamaSharp example shows

[steady oasis]

Code : https://gdl.space/lazuyugilo.cs

Problem : the bullet is not shooting correctly, what could be the problem? please help

[twilit scaffold]

sorry, i was not ignoring you at all. I has just walked away to do something, and when i came back, @somber nacelle had picked up the conversation

[steady oasis]

please mention me if replying

[river ridge]

Hi!

I've been banging my on this for a while, I smell some gotcha regarding articulation bodies, but I couldn't really find anything specific to them.
I can use rigidBody + Joints for this, but there is some other system that works with ABs nicely that I am trying to hook into, so I want to give it a good try before I change away from ABs.

Goal: Generate a string of objects (rope) given length etc. as public params to the root of the rope at start.
Observable problem: Child ropes are created at the given local position, but they snap to global coordinates through the AB on them, as if they were spawned as root, and then simply moved without the teleport method. (I did try teleporting the child too, got the error "this aint root" as I should.)
Annoyingly, the first child (the one connected to the root, R-c1) works as expected: it spawns SegmentLength away and stays connected. Every other child behaves as if its the first child...

Related bit of code:

// File and object: RopeLink.cs
void SpawnChild(int remainingSegments)
        {
            if(remainingSegments < 1) return;
            childRope = Instantiate(RopeLinkPrefab);
            childRope.transform.SetParent(this.transform);
            childRope.transform.localPosition = new Vector3(0, 0, SegmentLength);

            childRope.name = $"RopeLink_{remainingSegments}";

            var rl = childRope.GetComponent<RopeLink>();
            rl.Root = false;
            Debug.Log($"I am {transform.name} and i spawned {childRope.name}");

            rl.SpawnChild(remainingSegments-1);
        }

void Start()
{
    if(!Root) return; // dont spawn stuff if youre not the root
    SpawnChild(numSegments-1);
}

RopeLinkPrefab is set.
I have tried using Instantiate with the transform and parent parameters too, exactly the same behaviour.
Doing this manually in the editor works 10/10.

What am I missing about ABs and instantiating them here?

[stable osprey]

Answer: use rb.velocity = direction * bulletSpeed instead of rb.AddForce

[steady oasis]

so that would fix the direction?

[stable osprey]

facingLeft/facingRight is irrelevant since the direction is always facing the player

it will fix both speed and direction yes

[steady oasis]

oh yeh

thanks

[stable osprey]

you're welcome

[stable osprey]

hi, TLDR sorry 😛

[steady oasis]

can i add * Time.deltaTime so that the fps wont matter?

or it wouldnt work as supposed?

[stable osprey]

no, adding * Time.deltaTime is wrong

you're setting the velocity of the object, which is u = x/t -- includes dT already when translating to movement units

[steady oasis]

imma send u a video, a really funny bug 😂

[stable osprey]

I like videos

[stable osprey]

poor cow lol

[steady oasis]

😂

i mean as per the story #1265185860966682684, its def wrong

[steady oasis]

do i just make it trigger?

[stable osprey]

idk what you want -- but yeah how bullets interact with the world is an entirely separate system -- implement based on your design

I wouldn't mind the knockback in a game I was making -- I kind of dig it

[steady oasis]

the cow is the main character 😂

[steady oasis]

i will make it for a tank enemy, but how can i reduce the knockback?

[stable osprey]

make it explicit instead of letting the physics system handle it

explicit as in code specific AddForce event on impact

[steady oasis]

i dont understand

[white perch]

Yup, I was just unsure if using SerializeField would be the best way to store my assets (for example those like sprite of each building) and if there are any other optimal ways to do that. Thank you a lot 😄

[steady oasis]

so when the bullet hits the cow, the cow exerts force to the bullet to cancel out the force?

[stable osprey]

alright, so yeah first step make it trigger (if you want), then add an OnTriggerEnter2D(..) { cow.AddForce(dir * knockbackForce)

[steady oasis]

Ooo ohki, thanks

[stable osprey]

but that requires Cow to use force instead of velocity/transform for movement as well

[steady oasis]

also rate my game design in #1265185860966682684 too please

[stable osprey]

nah sry my mind ain't focused enough now for non-plain-code stuff xD still having coffee

[steady oasis]

its directly changing velocity just like we used in the bullet

[steady oasis]

😂

[stable osprey]

if the Cow uses velocity, you go into custom physics territory -- like coroutine with knockback

[steady oasis]

😭 nvm, lets wait for the tank enemy's turn

[unique flower]

Hello
I have a problem in input when i enter playmode the input names changes but the movement no
but when i change the inputs in the play mode it become fixed
how can i fix that?

[stable osprey]

Potentially something like this:

IEnumerator Knockback(GameObject bullet, float knockbackForce) { // Called from the TakeDamage(bullet)
    Vector2 dir = bullet.transform.position - cow.transform.position;
    float t = 0;
    while (t < 0.25f) {
        t += Time.deltaTime;
        cow.rb.velocity = -1 * dir * knockbackForce;
        yield return null;
    }
}

[stable osprey]

nice font! Which one is it?

[unique flower]

okk

[stable osprey]

what? 😄

[unique flower]

it`s a personal font to make my game not the same with any game
but the font doesn't look like that i change some things in the inspector

ok2

[stable osprey]

oh you created a font just for your game? cool

[unique flower]

no but i changed on a internet font to look like that
then can you help me in the problem please sad_cat

[steady oasis]

is there any way to not give knockback without using trigger? just asking

[stable osprey]

your question doesn't make much sense btw 😛 I've read it 3 times now still don't know what the issue is or what you want to fix

[unique flower]

i thkink is a unity glitch

[steady oasis]

did u try to build it and see ?

[stable osprey]

it'll always be buggy unless you handle it with a single system (either built-in physics or custom physics)

[unique flower]

no i tested it from the play mode first

but i will try

[lean sail]

i wouldnt really go with this approach tbh, its very reliant on the bullet still existing and directly setting the velocity of another rb is gonna be annoying for debugging later. Something like this could just be done by keeping track of what the knockback force was and then the rb itself applies these changes

[steady oasis]

yeh cuz i used addforce for my jetpack. it worked in the editor but not in the build ( android build )

[stable osprey]

you handle cow movement with velocity but non-trigger bullets apply force and depenetrate (depenetration likely causes the knockback you see)

[unique flower]

i will try

[stable osprey]

so it's buggy atm, but bugs can make nice features lol

[steady oasis]

yeh, that gave me an idea for a new enemy

[stable osprey]

was trying to simplify because of this :p

but yeah needs much more work for a proper custom knockback feature

[hard estuary]

To clarify, whenever you declare a field, it stores its content if it's a struct and stores the reference to content if it's a class. For example: when you serialize an int field, it stores its content, because int is a struct, but if you serialize Sprite field, it will only serialize reference to that Sprite, because it's a class. The reference usually takes only 12 byte of space. Also: multiple fields can refer to the same class, but can't do that with struct, they will just copy its content.

[steady oasis]

yeh maybe i will just stick to not making the bug into feature

[stable osprey]

it's a pretty cool feature tho just saying 😆

game would look much less "alive" if it flashed instead of getting knocked back

[steady oasis]

def adding to the list

but here is the thing, when there are like 10-12 enemies during boss fights, thats just a nightmare for the player

but, can be a good game design feature 😎

[knotty sun]

where do you get this 'The reference usually takes only 1 byte of space' ?

[unique flower]

did`nt work

i can anyone help me ?

[hard estuary]

I think I just memorized it wrong. Looked it up, turns out it takes 12 bytes in .net. Correct me if I'm mistaken.

[knotty sun]

12 bytes is correct. 1 byte would mean a maximum of 256 references which would be silly to say the least

[timid stone]

What's your manner of doing movement in your 2D games

Usually did a rb.velocity for player and such but just learnt about transform.translate

Was wondering if there were any others

Relative to Start and Awake, Awake would always occur and comes first whereas Start will occur after Awake and only if the object is active/enabled iirc

Start is called on the frame when a script is enabled just before any of the Update methods are called the first time. Like the Awake function, Start is called exactly once in the lifetime of the script. However, Awake is called when the script object is initialised, regardless of whether or not the script is enabled.
https://docs.unity3d.com/ScriptReference/MonoBehaviour.Start.html

[knotty sun]

for Unity Monobehaviours you cannot use a constructor

if it's a POCO, yes but then Start and Awake do not apply

hi not sure where this goes but Visual Studio intellisense does not show be comments above functions/properties - can I enable?

[dusk apex]

Maybe show an image to illustrate what you're seeing versus what you'd expect to see - I'm assuming you've seen a different image elsewhere with some proper "comments".

[placid summit]

ah, if you do a full xml comment with <summary> tags it seems to work. I was taking shortcuts and omitting the tags, which is ok for documentation generation, but apparently not here...

[trim schooner]

type 3 / to get this autocompleted

[placid summit]

I know but it was overloading my clean code with comments! I turned it off. I can at least edit to 1 line I suppose. Doxygen will grab any comment, unfortuantely visual studio seems not to and wants the specific summary in case there is further info

[trim schooner]

I know but it was overloading my clean code with comments!

I don't get this.. comments only exist that you add 🤔

[placid summit]

so by default typing /// adds multiple lines of comment with 3 for summary, plus all parameters. Yes you can edit after but... This can hugely increase length of code to scroll through... that is all. If there was a /// add 1 line summary add-on it would be nice...

generally I wants comments - but small 1 line ones

[dusk apex]

This isn't specific to Unity. You'll probably get better feedback in !csds

[storm wolf]

Are async methods ran on a different thread?

[leaden ice]

No

[storm wolf]

I am reading that they “dont block the main thread” but coroutines do. What exactly does this mean?

[little meadow]

I'd say they're quite similar...

[placid summit]

async is a bit of a mystery - you don't see it much in Unity code! But I see it much like coroutines. Coroutines delay the running of code until later and/or await the end of something. Nothing is multithreaded which is odd!

[little meadow]

You could run functions on other threads and wait for them using async-await... but that's not very common in Unity

[placid summit]

the docs talk on Coroutines: "yield: The coroutine will continue after all Update functions have been called on the next frame." In other words you are adding an immediate delay in the code to run the coroutine! But if the couroutine then yields for time or for an htttp call it makes sense...

which as @little meadow says is like async

[storm wolf]

Is it common to even use more than one thread usually

[civic isle]

no

i think unity does not support multithreading

[little meadow]

Depends on the perspective... Unity does it all the time, it's just that Mono's code is kinda limited to one thread...

[hard estuary]

I usually use job system for that.

[storm wolf]

Ok interesting

[placid summit]

you can use threads, but not access the Unity API in them, so limited...

[civic isle]

this is what i see

[knotty sun]

Unity does support milti-threading. it is only WebGL builds that do not

[civic isle]

i am surprised there isnt an easy way to multithread by now

[placid summit]

plus the engine itself is threaded (except sad webgl)

just not the 'main' thread

rendering etc

[tired elk]

Sometimes it's nice having such concept hidden behind a "complex" door. it prevents people not fully grasping the idea to use it i guess

¯_(ツ)_/¯

[hard estuary]

I feel like multithreading wouldn't be safe if it was easier. I think it's difficult mostly to prevent potential issues.

[placid summit]

I think the forums would be fullup double if Unity was all fully threaded - not having done it myself there will be many gotchas to making things thread safe - I know that much

[civic isle]

i dont know anything ab it

so yeah maybe id break everything

[placid summit]

I think there was talk of doing it in a way that would be safer. Does DOTs not allow this now?

[oblique spoke]

Regular C# threading has (always?) been available.
Unity has a Job system to make threading easier and safer https://docs.unity3d.com/Manual/JobSystemOverview.html

[civic isle]

Swag thanks

[placid summit]

ah that would be it. Of course they had to make their own system adding more change from core C#! But in this case may be in a useful way

[oblique spoke]

Instead of relying on portable, high performance, safely multithreading C# in 2018 era of Unity? 😛

[placid summit]

what changed in 2018? But yeah I should try it out one day - too much to do! Looks like may compile down to great C++ too with native arrays

[oblique spoke]

That's when the Job system (and early versions of a lot of DOTS initiatives) launched, which was during a time where C# was moving a lot slower.

[open bluff]

I want to create a Third Person Shooter character using the Unity "Animation Rigging" system. Is there a source for this?

[rigid island]

yes did you look it up ? so many examples esp on google

[open bluff]

Yes, github projects etc. I looked but couldn't find a clean project. Do you know of any clean project related to this?

[rigid island]

nah I build things, I don't grab random projects to start from

[open bluff]

Actually, I got to a point on my own, but I'm having problems with aiming, do you have any ideas on how to solve this?

[rigid island]

maybe. how should I know how to solve somethin you haven't explained yet

[open bluff]

Could there be a problem with this character? Looks like I did everything right

[rigid island]

looks fine to me

[acoustic sequoia]

he just chill like that

[rigid island]

the twisting is normal , you probably havent unchecked one of the axis (forgot which one, I think Z?)

under settings iirc

[open bluff]

I remember that I had removed the z axis, so I deleted this project when I couldn't fix it last time 😄 Now I will try again with a new project.

[open bluff]

👀 👀

[rigid island]

also another way I like to solve the looking behind with IK issue is adding a dot product or similar method to find out if I'm "twisting" too much compared to my character forward direction and rid of the "Weight" of ik

[open bluff]

I tried removing the other axes as well, nothing changed. I think the problem was due to the character

[rigid island]

only needed to remove 1, the rest are fine.

[acoustic sequoia]

Im creating a game template that i can use for any future game, any tips on how to make a save/load manager ? im thinking about how to make it as easy as possible for new components to become saveable and loadable with the manager doing all the heavy lifting... I know that i have to use an interface for the Isaveale and probably keep track of them all in the saveManager but im not really sure... do any of you have any experience with that?

[open bluff]

By the way, there is something I want to ask. How exactly should I track the aim point of the gun? I created an object and made it the child of the camera. Is there a better way than this or is this a good way?

[rigid island]

I have interface as well for anything I want to be ISaveable

[acoustic sequoia]

maybe check for relative rotation and start turning the whole character around before he becomes spine twisting?M

[rigid island]

thats what most games do yes

or just disable the IK looking back as I do sometimes

[acoustic sequoia]

yea thats a nobrainer but did you manage to make it easy for new saveables be simple to implement?

[rigid island]

I typically make pocos so yea

just add interface and its ready to go

[acoustic sequoia]

i was thinking about having a structure like

SaveManager -> GameData -> ISaveables

so that i can call from anywhere a game load/save and affect the ISaveable when i need it

but not sure if it just doesnt complicate it for no reason

[rigid island]

yeah I make all my Saveables register themselves to the savemanager

[acoustic sequoia]

are you having multiple scenes ?

like at once opened ?

[rigid island]

not typically. Unless maybe I'm carrying DDOL or a Canvas

you can still do it across scenes as long as the manager has an easy way to be accessed. Singleton helps with that

since cross-scene referencing don't work

[cunning burrow]

not my code but I wanted to filter a certain element, any way to do that? (it's just a panel with a centered render texture image

[rigid island]

loop through the results

[cunning burrow]

What is their type? What do I checkM

The docs are missing info

[rigid island]

RaycastResult. It says it right there

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/api/UnityEngine.EventSystems.RaycastResult.html

from there grab whatever component /gameobject you want

idealy you need something to make it distinguished from others if you have multiple of same components

[onyx cypress]

THE PLAYER DONT GO TO ANOTHER CHECKPOINT IS THIS SCRIPT RIGHT?

using UnityEngine;

    agent = GetComponent<NavMeshAgent>();
                               // Start at the first waypoint
    UpdateDestination();       // Set the initial destination
}

void Update()
{
    // Check if the agent is close enough to the target
    if (Vector3.Distance(transform.position, target) < 1f)
    {
        // Get the next waypoint
        WaypointIndex();
        // Update the destination to the next waypoint
        UpdateDestination();
    }
}

void UpdateDestination()
{
    if (waypoints.Length > 0)  // Check if waypoints array is not empty
    {
        target = waypoints[waypointIndex].position;
        agent.SetDestination(target);
    }
}

void WaypointIndex()
{
    waypointIndex++;
    if (waypointIndex >= waypoints.Length) // Wrap around to the first waypoint
    {
        waypointIndex = 0;
    }

one sec

forget it

[somber nacelle]

it's honestly impressive how bad some people are at following simple instructions

[broken light]

whats the simplest way to prevent more than one scriptable object of a type being created

in my case i have an item database scriptable object, so there should not be two of these assets in the project

need to make sure if that happens i can throw an error or something

[somber nacelle]

you could put some code inside of Reset that checks the asset database for another object of that type. of course you'd then also have to wrap that in preprocessor directives. or you could go the even more cursed route and make it a singleton

[broken light]

hmm i see i wonder why theres no built in attribute to prevent more than one

unless i should not use a scriptable object

[little meadow]

why do you care about it being one though? having multiple can be useful for testing things and whatnot, plus usually you don't accidentally make more, and even if you do, they shouldn't break things

[steep snow]

Sounds like you're describing the Singleton pattern there

[broken light]

yeh but its scene specific where as singletons are around for most of the application

[gray mural]

I don't think so.
Create your own class, derived from PropertyAttribute.
Create a CustomPropertyDrawer, derived from PropertyDrawer, for this class.
In a static method with the InitializeOnLoadMethod attribute, enumerate through the Assets with the AssetDabase.FindAssets method and find whether there is any other object of the desired type found.

[little meadow]

wait... so you have different SO class for each scene?

[broken light]

different instances of the database

[little meadow]

so... you do want more than one... I am confused

[gray mural]

Is this pattern also applied to assets?

[broken light]

oh sorry i even confused myself there lol. no there is only one SO asset file but it exists for specific scenes that load from it but not all scenes need it so its not loaded in for those scenes (addressable situation)

for example i dont need it on the main menu

[gray mural]

Well, if it's not about creation in assets, use a singleton pattern, as previously mentioned

[little meadow]

ah, okay... so... I'd generally just ignore this and just not make more instances 😄 unless it makes you really sad... in which case you can always make an something-something-asset-processor, which tells you "hey, these new assets were added" and you can then go through them, detect that some of them are not what you want and show the user a message "how about I delete those, huh?!" and then no matter what they pick - you delete them anyway to assert dominance!

[broken light]

can that still work with addressables

[gray mural]

Haven't worked with them, but they only make your assets accessable. How can it interfere with your singleton pattern?

[little meadow]

https://docs.unity.cn/2017.4/Documentation/ScriptReference/AssetPostprocessor.OnPostprocessAllAssets.html I think you can use this one to detect when a new asset thingy is created (there might be a nicer method to override though)

[spiral palm]

is there a way to get a specific peice of data from a json?

[broken light]

could use newtonsoft to read the file and then access the key directly

[spiral palm]

newtonsoft?

[olive bobcat]

Subclass or Dictionary?... that's the riddle! 🤔
Is it a subclass costly and heavy to store datas on the fly when you have about of 10/15 objects that interact with a trigger every ... mmm... 15/30 seconds?

[broken light]

json newtonsoft library

its a unity package in package manager

[spiral palm]

unity doesn't support reading specific parts of json natievly? eh ill install it, thx!

[broken light]

unity does the bare minimum for json

lol

[spiral palm]

it doens't appear in the unity package manager

[olive bobcat]

I have to manage a spaceship traffic, and I need to store about 5 or more different datas, so I was planning to use a List ... but a dictionary would be be |_____________ o _______________/ that long

So ... I was thinking about a subclass with a bunch of parameters.. it's easy to store it and also less chance to mess us with value 🙂

[spiral palm]

where is it?

[olive bobcat]

Yea, why not.. why I shouldn't use a subclass I like it so much in the end 😄
don't you think are nice? 😄

[wide terrace]

You can install it by name, com.unity.nuget.newtonsoft-json

[gray mural]

AssetModificationUtility
AssetModificationProcessorUtility
AssetPostprocessorUtility

[olive bobcat]

See the trigger?
when the ships enter on the right side of the trigger I have to store
Class of the ship.
steering value
engine speed
if it's player or not
fuel
agent which is driving the ship.

So I guess to make a subclass with all of that parameters could be a nice idea, so I will store the subclass in a List for all the ships that use the tunnel

🤔 Could be better than a dictionary... I guess.

[steep snow]

Dictionary has a key and a value, the value can be simple, an int, or a complex set of data in a struct or class

[onyx cypress]

this error happens when i press on select player mask in inspector

and READ the error messages, it's pretty obvious that they are NOT coming from your code

[frosty surge]

I have an egg falling (in the direction of rocks) and you can control it right and left using its rigidbody in x axis, i want to know how can i increase its fall speed by code overtime, lowering mass and drag didnt work

[rigid island]

mass does not mean anything in context of falling speed. You simply multiply the gravity by some const or whatever value you want

[frosty surge]

i cant access the gravity values from the rigidbody? Do i need to change the gravity value from setting for the whole project?

[rigid island]

yes if its only for a specific object you just add onto it via velocity/addforce

https://discussions.unity.com/t/changing-gravity-for-one-object/6282

[onyx cypress]

my monster only goes to three checkpoints

not all of them this is my code

[rigid island]

and shares the code wrong again

primo

[onyx cypress]

ok mate

isnt a big deal but ok

[rigid island]

making it inconvienet for someone to help you is the best way not to get help..

[onyx cypress]

ok

https://paste.ofcode.org/?edit=x8n6jNfdU3Ei3eSsn62gGR

[rigid island]

Here

this is wrong btw waypointIndex >= waypoints.Length

you always -1 the length for indexes

[onyx cypress]

oh

[rigid island]

as collections start from 0 index
10 items index can only go up to 9 etc.

[rigid island]

did you debug what the index is when it stops working

[onyx cypress]

yea

[rigid island]

ok..so what is happening

I don't have eyes on your project, by the code alone I cannot know if its wrong

[onyx cypress]

it always stops in the 3rd checkpoint

[rigid island]

alright so that would be index 2?

[onyx cypress]

so it only goes to each checkpoint 3 times

yea

[rigid island]

wdym each checkpoint 3 times? you mean it does all of them in array 3 times or you mean it only does the first 3

[onyx cypress]

yea only first three

then just stays there

[rigid island]

can you show where all the waypoints are placed

[onyx cypress]

if i move the thing it goes the same checkpoint it stopped

[rigid island]

so the index is still there at 2 ?

[onyx cypress]

yea

this is one of the checkpoints

[rigid island]

also what is the stopping distance of agent? is it less than 1 at least

[onyx cypress]

its 0

[rigid island]

alr can you record a short vid of whats happening with the agents inpsector visible

[onyx cypress]

ok sure

[rigid island]

not really seeing anything in the code that would stop it so early

[storm wolf]

Any way u can elaborate on this im a little slow I dont see the vision

[shell scarab]

Hey guys, the Packages folder should be in the gitignore... right? For some reason it's not in the gitignore.

https://github.com/github/gitignore/blob/main/Unity.gitignore

[knotty sun]

no it should not

[rigid island]

what do you want to know ? I myself try different methodologies

[shell scarab]

wait hold on it contains the manifest.... ok I guess "ProjectData~" inside of Packages should be in gitignore?

[storm wolf]

Like how do you go from just implementing an interface to it getting autosaved

Like for me I have to add my saveable stuff to the “PlayerData” before it saves

[shell scarab]

many large files inside of this "ProjectData~" folder

should I ignore Packages/package/ProjectData~/ or Packages/package/?

[storm wolf]

Also another thing the classes have to be serializable right that works with the interface too?

[knotty sun]

no idea what that is

[shell scarab]

Must be something new in Unity 6 or some package I installed did this.

[onyx cypress]

look skip forward a little bit

because the first time i recorded it i messed something up, skip forward when i play it again

[shell scarab]

ahhh @knotty sun I know what did it, Unity Visual Scripting. For some reason it initialized on my brand new project. It is something that needs to be ignored.

[rigid island]

ohh ok I see

[onyx cypress]

at 0:58

[rigid island]

yes

[rigid island]

My saving Class takes in Generics so I can pass whatever data I want

each ISaveable has their own Data they save to

[storm wolf]

U dont have [Serializeable] on the interface tho right

[rigid island]

somesave to GameData, other PlayerData etc.

[rigid island]

no

[rigid island]

Debug.log the Distance check and see whats going on there, start by trial and error

[storm wolf]

Wait what does it take in if the interface has Aa save method (im guessing)

[rigid island]

the only thing that knows about the interface is the Save manager

[storm wolf]

Whatt

[rigid island]

yes they each send their own struct/class to save in the final class that actually writes to file/cloud or whatever

I can give you a basic example but I'm not at my workstation rn. I have easier time showing than explaining lol

[storm wolf]

Any example would be helpful lol

[storm wolf]

Are you talking about a list of ISaveables

But then you would need to tell the objects they are isaveable

[rigid island]

the interface is in place to run specific method on all of them. or grab a specific item/struct

like .Save method lets say

[storm wolf]

Yeah i think thats the confusing part

But the objects arent ISaveable?

How do they call that method then

[rigid island]

the save manager

[rigid island]

an event usually starts the whole thing for me

[opaque vortex]

I would like to code my own SDK for users to upload their own custom avatars in my game, does anyone know where I can learn this?

[onyx cypress]

it ended on waypoint 4

[storm wolf]

The save manager is calling the interface method?

[rigid island]

print the distance i meant

[onyx cypress]

like what waypoint its aT?
