[stone lake]

you don't know any tutorials?

[sour fulcrum]

there's no magic link we have

[stone lake]

i mean thats fine i was just wondering, but thanks anyways

wait - I found this tutorial https://www.youtube.com/watch?v=ZEtKg9AyEJc . I'm not that knowledgeable on unity, but does it seem pretty substantial? That it might take a couple weeks to make at least?

[sour fulcrum]

sure

[polar acorn]

You're probably not going to find a tutorial that solves all your problems. The idea is to learn from many sources and synthesize them into your own internal understanding of the process, rather than just parroting videos other people have made

[stone lake]

you're right

i guess i can just start with this and try adding stuff later

[polar acorn]

You don't need to vet a tutorial to see if it's "worth your time", just learn from anything you find

[rough granite]

Just not the ai

[polar acorn]

Well, you do need to learn "Stay the hell away from it" so there is still something to learn there

but yes, stick to actual sources that have actual knowledge

[lyric igloo]

can some one can help me with making my ai use a sward? https://paste.mod.gg/zniibrhyhtkg/0

[solar hill]

love ambiguous help requests with minimal context

[lyric igloo]

what more you need

[slender nymph]

pretty sure they just want someone to hold their hand and make it for them

[polar acorn]

As an example, here's a completely valid answer to the question, as posed:

Make a "sward" object as a child of the player. Done.

If you want more than that, you will need to actually say what you want

[solar hill]

also you sent your code

but it has nothing to do with swords of any kind?

so the question is did you even attempt to do it on your own

or did you decide hey ill have these guys on discord do it for me?

[lyric igloo]

i have no idea how

[solar hill]

so break it down

[lyric igloo]

how do i do it without knowing how

[solar hill]

you learn how to do it

[lyric igloo]

yeah where

[solar hill]

first you break down your problem into multiple stages

the internet is a vast resource of knowledge

[polar acorn]

First step is to actually know what you want

[slender nymph]

you need to start be deciding what it means to "use a sward"

[polar acorn]

"use a sward" isn't actionable

You need to actually describe it

[lyric igloo]

yeah ok ill go search it i did alrady but more deap ig

[solar hill]

i doubt you did but whatever

[lyric igloo]

that he will reconize when the player is in front of him and hit him with the sowrd

[runic basalt]

Is there a way to make decals only display on certain objects? I have a drill where I drill into a ceiling and I use a projector for the hole mark. But when the drill is still close up to the wall, the decal shows up on the drill. I created a rendering layer called decal, and set the projector's rendering layers to the decal layer, then I set the walls to have the decal rendering layer and no other objects have it. But still the decals are projected on other objects.

[slender nymph]

you need to break it down into actionable steps first because just searching "how to make ai use a sward" isn't going to get you anywhere. you need to first define what that means, break it down into smaller steps that you can research and put that knowledge together after researching how to complete each step

[solar hill]

incredible juxtopositing within this screenshot

[slender nymph]

this is literally the worst possible way to research anything

[polar acorn]

There you go, that's more actionable. Now, you need to find out how to detect when an object is in front of another. Then you need to decide what "hit him with the sword" means

[lyric igloo]

yes you all right i will break it down and serch it like that thank you

[magic temple]

Hi, People

I need, Sanity with someone who can explain the "Coroutine" thing

Because I have a lot of issue with it, but I want to use that technologie, I know what is for (like a simulator of waiting for script) but I need a person how can help me with my bugs

[wintry quarry]

Do you have a specific question about them, or you're just completely lost on the whole concept?

what bugs do you have?

Share your code and explain what's going on

[polar acorn]

Coroutines, once started with StartCoroutine, run like normal functions, one line at a time, top to bottom, until they hit a yield statement. That statement will then pause the coroutine and go back to the line after StartCoroutine and resume from there, until the yield instruction tells it to resume. The simplest yield instruction is yield return null, which will resume the coroutine from that spot next frame.

[magic temple]

Context : I create a Computer in my 2D isométric game, the player click on collider2D, and bom the prefab computer Spawn.

The thing is, its just a text thing right now, So, for that, I use Addressable for load a JSON file who have all the text that I will need.

And the principal issue is 2 thing, 1. A error that appair (but I thing I fix it somehow) that saw "I am Coroutine, I can't work because your gameobject (the computer) is Inactive !" But I try like, FORCE the unity to active it even I saw in my inspector the gameobject never been desactivate, but yea that thing break my mind, and its not the worse.

And Second one its the .. loss of my data, Like in my script That I will show you, I stock my text from JSON to a Variable that is a tab in a tab, and the thing that, its working good, but when Im outside of the function, its .. become null ? I will show you my code

[wintry quarry]

I create a Computer in my 2D isométric game, the player click on collider2D, and bom the prefab computer Spawn.
Nothing about this sounds like something that you would need a coroutine for.

A error that appair (but I thing I fix it somehow) that saw "I am Coroutine, I can't work because your gameobject (the computer) is Inactive !"
Can you share the code you used and the actual error message you saw?

loss of my data, Like in my script That I will show you, I stock my text from JSON to a Variable that is a tab in a tab, and the thing that, its working good, but when Im outside of the function, its .. become null ?
This sounds like a totally separate issue

[magic temple]

I use the Coroutine for give time to Addressable a moment to Load a 4 line of Json, yea sound stupid but im new and IA are not so useful

[wintry quarry]

ok yeah you'll need to show your code and any error messages you saw

[swift crag]

what are you invoking the coroutine on?

[magic temple]

I have 3 script, script one :

[swift crag]

you may be trying to start the coroutine on the computer prefab itself

[swift crag]

and I'm pretty sure that prefabs do not count as being active

I hope its work

• In you will found Comparator, his job its to Compare Tags of GameObject, I create a Point and Click so I need to know what is for.
• ComputerManager its the Brain of the Computer, he will be the bridge of the player input and the Computer.
• ComputerTextManager a Brain too for Text of the Computer

[magic temple]

Been trying without the prefab, the problem stay sadly the same

[magic temple]

Im sorry, I don't think I understand the question

[polar acorn]

What object is calling StartCoroutine

[magic temple]

I have a lot of StartCoroutine

[naive pawn]

the one you have issues with

check its stacktrace and see which line it's coming from

[magic temple]

oh

[naive pawn]

then you can work backwards from there

[magic temple]

with the ComputerManager and the TextManagerComputer

From ComputerManager : IEnumerator Start()
{
yield return new WaitUntil(() => _ComputerTextManager.IsDataReady);

    _ComputerTextManager.Load(ComputerTextManager.Sections.Login, 0);
}
public void Launch()
{
    Start();
}

[naive pawn]

you aren't starting a coroutine there

[magic temple]

and the TextManagerComputer :
private void OnJsonLoaded(AsyncOperationHandle<TextAsset> handle)
{
if (handle.Status != AsyncOperationStatus.Succeeded)
{
Debug.LogError("Failed to load JSON Addressable.");
return;
}

    try
    {
        CurrentData = JsonConvert.DeserializeObject<SectionsData>(handle.Result.text);
        Debug.Log("JSON chargé avec succès !");
    }
    catch (System.Exception e)
    {
        Debug.LogError("JSON parsing error:\n" + e);
    }
}

[swift crag]

when you call Start(), you create an object: but just creating it does not do anything

[naive pawn]

please don't send these plaintext code snippets

it's.. very hard to read

[magic temple]

Yea, its say that my gameobject its not active

[magic temple]

Sorry :c

[swift crag]

it has to get passed to StartCoroutine for Unity to start running through it

[magic temple]

Im paniking

[naive pawn]

what is saying that

[magic temple]

A error from the Coroutine System (not mine)

wait I will found it

[naive pawn]

show the actual error

you literally just do not have a coroutine there

[swift crag]

the only StartCoroutine in your code is on line 103 of ComputerTextManager.cs

[swift crag]

StartCoroutine(...) is equivalent to writing this.StartCoroutine(...) -- you are calling the method on a specific object

Importantly, if this object is a prefab (and not a copy of the prefab), this won't work

[swift crag]

You need to instantiate the computer, then start coroutines on that copy's components

you cannot start coroutines on the prefab's components

[magic temple]

Coroutine couldn't be started because the the game object 'Computer' is inactive!
UnityEngine.MonoBehaviour:StartCoroutine (System.Collections.IEnumerator)
ComputerManager:Launch () (at Assets/Script/BuildIn/Machine/Computer/Manager/ComputerManager.cs:92)
Comparator:MachineCompare (UnityEngine.Collider2D) (at Assets/Script/Interaction/Zone/Player/Comparator.cs:156)
PlayerControl:OnTrigger (UnityEngine.InputSystem.InputAction/CallbackContext) (at Assets/Script/Input Manage/Player/global/PlayerControl.cs:176)
UnityEngine.InputSystem.LowLevel.NativeInputRuntime/<>c__DisplayClass7_0:<set_onUpdate>b__0 (UnityEngineInternal.Input.NativeInputUpdateType,UnityEngineInternal.Input.NativeInputEventBuffer*)
UnityEngineInternal.Input.NativeInputSystem:NotifyUpdate (UnityEngineInternal.Input.NativeInputUpdateType,intptr)

[swift crag]

ah, you've modified the code since sharing it

This is the same problem, though

[magic temple]

that is when I add a "StartCoroutine(Start())"

[swift crag]

You are calling Launch() on the prefab itself

the prefab object doesn't really exist

it acts like a deactivated game object

[magic temple]

oh

that suck

How- How I use it

If its "don't exist" ?

[naive pawn]

you need to be calling Launch on an instance of the prefab

the prefab does exist, but not in a scene

you need something in a scene

[swift crag]

I would expect this prefab to be placed in the scene

currently, your code does this...

public bool MachineCompare(Collider2D hit)
{
    GameObject obj = hit.GetComponentInParent<Transform>().gameObject; // met une sécurité ici

    if (obj.CompareTag("Computer"))
    {
        if (GetReferenceComputerManager())
        {
            _ComputerManager.Launch();
        }
        else
        {
            Debug.Log("Null!");
        }
            return true;
    }
    return false;
}

[magic temple]

Its "place" by Addressable

[magic temple]

yep, its mine

[swift crag]

It's looking for an object in the scene, but then you just go to _ComputerManager and call Launch() on it

If ComputerManager is a "singleton" – something that there is only ever one copy of – you should instantiate it and then use the resulting copy

If it isn't – so each computer in your scene needs its own ComputerManager – then it should be attached to those computer objects

[magic temple]

So, Basicly, if I understand

My problem its that a Prefab its a ghost for Unity, and for that, I need to create a Gameobject that can be the Brain of the prefab ?

[polar acorn]

A prefab is a GameObject that lives in a file

Files cannot run coroutines

You need to run the coroutine on an object in the scene

[magic temple]

ok so

That I can fixe it, Thanks you

but I need a understanding with the last bug

The "Lost Value" of ComputerTextManager

    private void OnJsonLoaded(AsyncOperationHandle<TextAsset> handle)
    {
        if (handle.Status != AsyncOperationStatus.Succeeded)
        {
            Debug.LogError("Failed to load JSON Addressable.");
            return;
        }

        try
        {
            CurrentData = JsonConvert.DeserializeObject<SectionsData>(handle.Result.text);
            Debug.Log("JSON chargé avec succès !");
        }
        catch (System.Exception e)
        {
            Debug.LogError("JSON parsing error:\n" + e);
        }
    }

here to be precise, with CurrentData

I trying Debug.Log with it, and its show all my data, even when I modify the JSON

But when Im out of that function, the CurrentData Lose all his data

[naive pawn]

consider putting your description of the issue into a single message please

[magic temple]

my bad, a bad habit of mine

[polar acorn]

Where do you declare the CurrentData variable

[magic temple]

    private string Addressable { get; set; } = "MachineComputerText";
    private SectionsData CurrentData { get; set; }
    private Coroutine TypeCoroutine;
    private AsyncOperationHandle<TextAsset> handle;
    public bool IsDataReady => CurrentData != null;

[naive pawn]

• are you assigning to it anywhere else
• are you sure you're checking in the same instance

[polar acorn]

Okay so that would be an object scope variable. That means it doesn't get lost when you leave the function

[magic temple]

all in that file : https://paste.mod.gg/vsiornhhbtdb/2
But 1. No
2. What is a instance ?

[magic temple]

Its a normal world

But in my unity, its losing

[magic temple]

Like what I have its not normal

[polar acorn]

No, it isn't. Either you're overwriting it somewhere between when you set it and when you check it, or you're looking at a different object that didn't have OnJsonLoaded called on it

[magic temple]

My english its not my primary language, sorry if its bad-

[naive pawn]

a class is like a blueprint. when you instantiate that class (in unity, when you attach a component to a gameobject) you create an instance of the class. each instance exists separately from every other instance

[magic temple]

public bool Load(Sections section, int index, float delay = 1f, float delayPerChar = 0.03f)
    {
        if (CurrentData == null)
        {
            Debug.LogWarning("JSON not ready yet.");
            return false;
        }

        Data[] array = section switch
        {
            Sections.Starting => CurrentData.Starting,
            Sections.Login => CurrentData.Login,
            _ => null
        };

        if (array == null || array.Length == 0)
        {
            Debug.LogError($"Section {section} is empty or missing.");
            return false;
        }

        if (index < 0 || index >= array.Length)
        {
            Debug.LogError($"Index {index} out of range for {section}. Length={array.Length}");
            return false;
        }

        if (TypeCoroutine != null)
        {
            Debug.Log("Il est nulle le Coroutine");
            StopCoroutine(TypeCoroutine);
        }

        TypeCoroutine = StartCoroutine(
            TypewriterEffectWithDelay(array[index].text, delay, delayPerChar)
        );

        return true;
    }

Here is the only function that use CurrentData

[naive pawn]

and where do you call OnJsonLoaded

[magic temple]

in the same file

[naive pawn]

that doesn't help

[magic temple]

.. Like, upper ? On the Awake() ?

ooh

[polar acorn]

So either you are setting CurrentData to something else, or the thing you're calling Load on is not the same thing you're calling OnJsonLoaded on

[naive pawn]

what method chain links OnJsonLoaded to Load

[magic temple]

yea, in the Awake()

[naive pawn]

no, you aren't calling it there.

[magic temple]

Load its to Load the text, but I have a Event Variable that in the coroutine of ComputerManager make the "click" event wait until the function OnJSLoad finish his work

[polar acorn]

Where are you calling OnJsonLoaded and what object are you calling it on?
Where are you calling Load and what object are you calling it on?

[magic temple]

?

    private void Awake()
    {
        handle = Addressables.LoadAssetAsync<TextAsset>(Addressable);
        handle.Completed += OnJsonLoaded;
    }

I can bad understand your question, sorry about that

[polar acorn]

Okay, so, this will run OnJsonLoaded on this object when handle.Completed is invoked.

Now what about Load

What calls Load

[naive pawn]

@magic temple what info is telling you that CurrentData is gone? the JSON not ready yet. log is triggering?

[naive pawn]

(they shared the complete code above btw. that's gonna be much easier than this game of telephone)

[magic temple]

Here is the full script (modify for discord) :

    private void Awake()
    {
        handle = Addressables.LoadAssetAsync<TextAsset>(Addressable);
        handle.Completed += OnJsonLoaded;
    }

    private void OnJsonLoaded(AsyncOperationHandle<TextAsset> handle)
    {
        if (handle.Status != AsyncOperationStatus.Succeeded)
        {
            Debug.LogError("Failed to load JSON Addressable.");
            return;
        }

        try
        {
            CurrentData = JsonConvert.DeserializeObject<SectionsData>(handle.Result.text);
            Debug.Log("JSON chargé avec succès !");
        }
        catch (System.Exception e)
        {
            Debug.LogError("JSON parsing error:\n" + e);
        }
    }

    public bool Load(Sections section, int index, float delay = 1f, float delayPerChar = 0.03f)
    {
        if (CurrentData == null)
        {
            Debug.LogWarning("JSON not ready yet.");
            return false;
        }

        Data[] array = section switch
        {
            Sections.Starting => CurrentData.Starting,
            Sections.Login => CurrentData.Login,
            _ => null
        };

        if (array == null || array.Length == 0)
        {
            Debug.LogError($"Section {section} is empty or missing.");
            return false;
        }

        if (index < 0 || index >= array.Length)
        {
            Debug.LogError($"Index {index} out of range for {section}. Length={array.Length}");
            return false;
        }

        if (TypeCoroutine != null)
        {
            Debug.Log("Il est nulle le Coroutine");
            StopCoroutine(TypeCoroutine);
        }

        TypeCoroutine = StartCoroutine(
            TypewriterEffectWithDelay(array[index].text, delay, delayPerChar)
        );

        return true;
    }
}

[polar acorn]

It doesn't include where they call the function from

[polar acorn]

So what calls Load

[naive pawn]

it does

[magic temple]

The :

        if (CurrentData == null)
        {
            Debug.LogWarning("JSON not ready yet.");
            return false;
        }``` 
in Load

[polar acorn]

Where?

I didn't see that bit

[magic temple]

https://paste.mod.gg/vsiornhhbtdb/2

[naive pawn]

ComputerManager.cs:88

[magic temple]

here

[naive pawn]

and does that trigger

[polar acorn]

Oh there's multiple tabs

I didn't even notice

[magic temple]

yes

hehe

I put a lot of that thing that I call 'Dog cage'

like a security thing

[polar acorn]

Okay, so _ComputerTextManager is the object that runs Load. Which object is that referring to?

[naive pawn]

have you tried checking CurrentData after you load it

[naive pawn]

...the guard clauses?

[magic temple]

a empty gameobject in the prefab

[polar acorn]

In the prefab

[naive pawn]

well, obviously not empty

[polar acorn]

the one that doesn't exist in the scene

and therefore cannot run Awake

[naive pawn]

in the prefab or in the prefab instance?

[polar acorn]

which means it can't have had OnJsonLoaded called on it

[magic temple]

wait wait

One thing

[naive pawn]

i mean, obviously the same object that is being checked for IsDataReady 2 lines above, so...

[magic temple]

When I start the game, the prefab charge, and the Text from the JSon are loaded in my view of player

but when I trying like, control the text, the CurrentData say to me that its null

that is the issue

[naive pawn]

this doesn't answer any of our questions

[magic temple]

Ah-

SOrry-

[magic temple]

In.. the prefab Familly

[polar acorn]

How about you share the stack trace of the thing that says its null

[naive pawn]

that's.. not a valid answer

[magic temple]

like its a multiple hierachie with parent

A group ?

[naive pawn]

that's unrelated

[magic temple]

I terribly sorry

[naive pawn]

is it in an instance of the prefab, in a scene

[magic temple]

Like-

In the Scene when load ?

Load the prefab, not the function

[polar acorn]

The prefab file, and the instance in the scene are not the same object

They are two different objects that both have this script on them

You are calling OnJsonLoaded on one of them, and then checking the other one to see if the data is set

And, since it's a different object, that one doesn't have CurrentData set

[magic temple]

I gonna show you I think

here, Computer have the ComputerManager Script, annd ComputerTextManager have the .. computerTextManager

[naive pawn]

crop less

this does not contain the info asked

[magic temple]

.. Im so confuse

[naive pawn]

we are asking whether or not the object is in the scene

we don't particularly care about the specific hierarchy

[magic temple]

Not when I not "trigger it" with Comparator, when its call, Comparator.cs Call a Addressable to be in the scene ?

public bool MachineCompare(Collider2D hit)
    {
        GameObject obj = hit.GetComponentInParent<Transform>().gameObject; // met une sécurité ici

        if (obj.CompareTag("Computer"))
        {
            if (GetReferenceComputerManager())
            {
                _ComputerManager.Launch();
            }
            else
            {
                Debug.Log("Null!");
            }
                return true;
        }
        return false;
    }

[naive pawn]

that code is not relevant

do you have instances of these components in the scene or not

[magic temple]

Say me a exemple

[naive pawn]

do you know what a scene is

[polar acorn]

Is there an object with a ComputerTextManager component in the scene

[magic temple]

ye

[magic temple]

No

[naive pawn]

that is the main cause of your issues

[polar acorn]

Then you have nothing with CurrentData set

Because Awake does not run on prefabs

[magic temple]

When why I have my Text from the JSon in the TextMeshPro in Computer ?

[naive pawn]

what are you even looking at

[magic temple]

If I can't have the information, how I see it

[polar acorn]

Probably because one of the things you've said so far is a lie

And I have no idea what

because I cannot see what you see

and you have to actually provide information

[naive pawn]

jesus christ just take a screenshot of your entire unity window

[magic temple]

I can, like, show you in a vocal or something

[naive pawn]

no

[magic temple]

Brother-

[solar hill]

theres also no voice chats here

[magic temple]

Im not here to lie, im seeing what im seeing

[naive pawn]

maybe you didn't knowingly lie, but something you've said is wrong

[magic temple]

When I click on the trigger, the prefab spawn and the text from the json its loaded

[naive pawn]

what are you clicking on

[magic temple]

Collider2D

[naive pawn]

an instance of the prefab in the scene? or what exactly?

that gives me no info at all

[magic temple]

wait

I will show you

that little block its my Collider

he have a tag

and Comparator will .. compare that tag

if the tag its correct, the prefab are call

Do you want that I Screen Share ?

[naive pawn]

no

[magic temple]

aww

[naive pawn]

and to be clear, the computer isn't inside the canvas or the maincamera, right

[magic temple]

Oh

im

Well, the prefab have a canvas, but its not IN a canvas

[naive pawn]

god

[magic temple]

Im new at Unity, Im trying-

[naive pawn]

the computer isn't inside the object inside your scene named "Canvas" or the object named "MainCamera", correct?

[magic temple]

yes

[naive pawn]

this is basic english

[magic temple]

" but its not IN a canvas" and I think I make it thew

[naive pawn]

cool, then we've established one of the things you've said is correct - the computer is not in the scene. there does not exist a Computer instance, which you need to be able to do things in unity

that is your main issue

[magic temple]

alright, when, why use a prefab ?

[naive pawn]

when you want to use a gameobject as an asset, one you can reuse in multiple places, and you can modify that asset and have that change propagate to all its instances and variants

[magic temple]

But then, how is it possible that when the prefab is activated and put on the scene, I can see the text from my JSON in the “Game” view? Even though it's not supposed to retrieve anything because everything that is read in the JSON and put into a variable is in Awake()?

[naive pawn]

no clue what you're referring to at this point tbh

is the prefab being instantiated from some other object?

if not,

when the prefab is activated and put on the scene
this just isn't happening.

you also haven't really shared what exactly you're looking at in the gameview

[magic temple]

yep, the gameobject Comparator

[magic temple]

how can I ?

[naive pawn]

in Comparator.cs? you don't have any Instantiate calls there.

[naive pawn]

a screenshot would do

[magic temple]

here a video

[naive pawn]

ok, so you have a Computer(clone) there. sounds like that's an instance of your Computer prefab

probably something else is instantiating it

yeah ok, this is starting to make sense.

[magic temple]

The only thing installed on Scene is the Empty Comparator game object, which contains the comparator.cs script.

[naive pawn]

well that's obviously not correct

[magic temple]

enlighten me

[naive pawn]

right now you have 2 instances of the ComputerManager/ComputerTextManager.

one in the prefab, one created later in the scene, at runtime.

the one created in the scene is handling itself. the ComputerManager.Start coroutine is being executed, ComputerTextManager.Awake is being run, etc.

the prefab one is getting its ComputerManager.Start called separately or something, maybe through Launch (which probably should not exist), there's that weird AutoAssignAssetReferences in Comparator. you definitely don't need anything like that

[magic temple]

AutoAssignAssetReferences its a Script that I create to Found all my forgetin References, its a security for people that work in my project

[naive pawn]

sounds like something that would only cause problems tbh

why does something DDOL need to persistently reference something in a specific scene anyways

[magic temple]

what

how do you do it?

[naive pawn]

with serialized references or with singletons where that makes sense

something DDOL like that wouldn't be written for something in a specific scene anyways

and i don't see why you'd instantiate it at runtime, why not just have it in the scene

[magic temple]

Because I'm changing scenes, and I want to keep important game objects such as Player or bluidin.

[naive pawn]

that doesn't really change any of what i said

[magic temple]

Well, be more specific.

[naive pawn]

ive been pretty specific

what you said simply is not relevant to what i said

is Comparator specific to this scene, or is it used for many scenes?

[magic temple]

Used for many scenes

The player will go through the scenes for various reasons, so in order to know what it's used for and where it clicked, I need scripts that won't get lost.

[naive pawn]

then why is it written with stuff specific to this one scene?

[magic temple]

? its not only for One scene, its for 'all' scene

 public async UniTask<bool> Zone(Collider2D hit)
 {
     if (!hit)
     {
         return false;
     }

     GameObject obj = hit.GetComponentInParent<Transform>().gameObject;

     if (obj.CompareTag("GreenZone"))
     {
         return true;
     }

     if (obj.CompareTag("RedZone"))
     {
         return false;
     }

     if (obj.CompareTag("InteractiveZone"))
     {
         return await _InteractiveZoneController.OnInteractiveZone(hit);
     }

     if (UnityDebugLog)
     {
         Debug.LogWarning("[Comparator](Zone) Aucun tag reconnu.");
     }

     return false;
 }

Like here, its for the scene Outside, Dortory1, Village..

I'm trying to limit scripts, not give each scene its own script, which kills performance.

But what's the point? Why are we having this discussion? It won't help you understand my problem.

[naive pawn]

MachineCompare seems to be written with just this scene in mind

[naive pawn]

...you asked... #💻┃code-beginner message

[naive pawn]

something like this would not be anywhere near killing performance

[magic temple]

I plan to install another machine, so comparing which machine the player interacts with is the purpose of comparator.cs.

[naive pawn]

why not just have each machine manage itself

that would be much simpler

[magic temple]

Simple does not mean more efficient

[naive pawn]

efficiency does not matter at this scale

[magic temple]

And I have a constant mind of saving every single frame.

[naive pawn]

that's a very common beginner pitfall, premature optimization will only give you more workload for nonexistant results

[magic temple]

Not for me

[naive pawn]

optimize when you have issues

make it an interface even, IInteractable, check if you've clicked an IInteractable in the player, call the Interact method
the machine implements IInteractable and plays the text when you interact with it, or whatever.

[naive pawn]

computers are fast. you could have 5000 comparators in the scene and probably not notice any difference at all

[slender nymph]

if you're looking for peak efficiency then don't make a game at all. it's more efficient to imagine you are playing a game because that doesn't use any of your computer's resources and can run at a framerate that matches the speed of your thoughts

[naive pawn]

you have other issues to worry about at this stage

make something work before making it good. and making it simple to work with is a very important step to making it work

[brazen heart]

Hey guys I'm having a few issues with inputs in Unity
I'm really new to the engine so forgive me if I don't understand some things
Basically I have a button and when I click it I have a line to simply log it in the console but no matter what I've tried, nothing works

[magic temple]

I don't think we share the same way of thinking. My goal is to rack my brains, understand the very core of Unity, try to understand the issues, and that's what fascinates me, not making infinite loops and hoping no one notices.

[naive pawn]

simple code makes issues easy to understand. you aren't trying to understand unity here, you're trying to understand issues created from your own convoluted code

[slender nymph]

1. make sure you are referencing the correct buttons and not prefabs or whatever in your variables
2. make sure you have an event system in the scene
3. make sure that Awake is actually running too

[naive pawn]

also make sure you've added that component

[magic temple]

Is your goal to give your future self more work and headaches and call it “pro dev”? I'm taking things into account right now, as any good developer should.

[solar hill]

youre giving yourself more work and a headache now

so what are you really accomplishing here

[magic temple]

The goal is to give my future self a vacation, not the other way around.

[naive pawn]

ok, so design your systems to be easy to work with

[solar hill]

even if you created perfect systems and configurations now you will still have other challenges down the line

like this is just the nature of development

[brazen heart]

I have one object that has a mono behavior for the buttons and I have them referenced here
You're gonna laugh but idek what a prefab is
I'm a complete beginner in this engine

[slender nymph]

your future self is going to have plenty of vacation time when you abandon the project because you are developing yourself into a corner with all this preemptive microoptimization

[solar hill]

sometimes you gotta relax and think "we will burn that bridge when we get there"

[magic temple]

So, I sacrifice the player so that I can “read” what I've done better?

[naive pawn]

when did i say that

[slender nymph]

great! now check the other two points

[solar hill]

also what do you mean sacrificing the player

[magic temple]

Dude, do you need psychological help?

[solar hill]

thats not very nice

[naive pawn]

i'm saying to think about your systems and use simpler, more direct, more maintainable, easier to debug, methods of referencing other objects

[brazen heart]

I do have an event system and the music does play so I assume the awake is running?

[solar hill]

love the implication that a player would give a shit if a system they dont know about in a game they are playing isnt perfectly optimal

just a reminder clair obscur just won game of the year and it runs like shit

people dont really care anymore

the bar for performance is so low it might as well be a chalk drawing

[magic temple]

That's the whole problem with developers, and I'm not the only one saying it: you make life easier for yourselves rather than improving the player experience. Personally, I try to rack my brains as much as possible to offer a game that can run on even the worst PCs, rather than expecting players to have a good computer.

[naive pawn]

validate that assumption, add a debug log to Awake

[polar acorn]

The fastest possible code is one that doesn't run

[solar hill]

yeah i doubt whatever happening here is going to have such catastrophic performance issues that will make it so that a slightly weaker pc cant run your game.

[naive pawn]

good thing my suggestions would both make your life easier and your game better, because it would allow you to actually make progress with your game instead of worrying about microoptimization

[slender nymph]

i'm being realistic. you are doing things out of order in some harebrained attempt at making yourself need to work less later, when you are making your workload now even larger than what it would have been overall if you started with "make it work" before "make it fast"
the order should be make it work -> make it good -> make it fast
otherwise you're going to run into issues now while attempting to make it fast before it even works, then when it isn't good and you need to redesign you need to do even more work

[brazen heart]

Checks out

[solar hill]

youre also optimizing your game for the 1% of the 1% which isnt good

[magic temple]

I mean, the guy says to give up all hope or worse—I'm seriously worried.

[polar acorn]

So what's your data showing how much this affects the system requirements of the game? If you're willing to make a complicated system surely you have analytics of how much it saves, right?

[slender nymph]

can you show a screenshot of the inspector for the event system you have in your scene

[naive pawn]

lmao no? they're giving an extreme example that focusing purely on premature optimization will just burn you out

and they're correct

[solar hill]

is that what he is saying?

or are you just not listening

[polar acorn]

Considering how hard we had to explain the difference between a prefab and an instance, you probably shouldn't be worried about efficiency.

[brazen heart]

Sure thing

[slender nymph]

and the buttons are attached to the canvas, right?

[brazen heart]

Yeah

[magic temple]

My own PC is crap, so if my game runs on it, that means I've done a good job. Then I'll look for other more advanced tools to ensure precision.

[slender nymph]

is it a world space canvas or a screenspace canvas?

[naive pawn]

ok, if you have issues running it on your pc, then start worrying about optimization. anything else is premature

[brazen heart]

screenspace

[polar acorn]

And how do you know that what you're doing isn't making it worse

[naive pawn]

ensure precision.
you'd rather it runs fast more than it running correctly?

[polar acorn]

What data are you comparing it to?

[slender nymph]

and your canvas has a Graphic Raycaster on it, yes?
and the images on the buttons do not have "Raycast Target" unchecked?

[solar hill]

also i dont think you are being very fair to the people who were helping you for the past hour

[polar acorn]

Do the buttons visibly respond to the mouse? By default they should change color when you hover or press them

[brazen heart]

That's probably what it is
Both were checked on

[slender nymph]

oh wait, sorry had that reversed it must be checked

[magic temple]

That's what I do. I start with something basic, and if it works, I make it more complicated, optimize the code, and try to figure out how I can improve it. In short, why are you doubting me on this? It's not the first time I've worked with code.

[naive pawn]

@magic temple literally everyone here has been a beginner before.
many of us have encountered many of the issues we're referring to. this advice has been from collective experience

[brazen heart]

Oh, ok yeah they are checked

[polar acorn]

Yeah, that's what they're supposed to be, you want it checked on things you can click on. Make sure nothing in front of them has that checked

[brazen heart]

Also no they visibly don't respond to clicks

[solar hill]

you keep responding to certain messages as if they are saying something completely different than what they actually are

you immediately become hostile at the slightest bit of valid criticism

[brazen heart]

I have a graphic raycaster in the canvas and both are checked

[slender nymph]

and to be clear, you have clicked into the game view before testing any of this, yes? because the game view needs to be focused for the event system to properly work with your input

[naive pawn]

you have this backwards. you need to improve it before worrying about optimizing it

[polar acorn]

You might have an invisible hitbox in front of them, try disabling any other objects but the button and their parents, then try to click on them

[magic temple]

Is your advice “do something that works before adding glitter to it”? Because that's how I work, except that RIGHT NOW I'm in the OPTIMIZATION phase, so it's normal that I'm stuck on it.

[naive pawn]

you have broken code

what do you mean you're on the optimization phase

you need to make it work first

[polar acorn]

Okay, so it works as expected, it's just slow?

[magic temple]

Avoided addressable, doing something more “the hard way,” without prefab, without all those coroutines... In short, yes, I went through those steps, and now I'm improving what I've created. Why is it such a big deal to you?

[naive pawn]

....what?????

i gave you advice on how to improve your code

[brazen heart]

Wait that's what it is omg
I had a fade object over everything and just completely forgot that it blocks inputs
I unchecked raycast target on it and it works, ty guys for the help
As you can tell I'm super new to unity

[magic temple]

Is the code broken because I'm optimizing it?

[naive pawn]

if you consider what you're doing now to be optimization, then yes

[magic temple]

Well, thanks you, a advice still a advice

[magic temple]

No, its

Like, People

Please, why are we even talk about it

[polar acorn]

It's good, UI problems got way harder to debug lately. Used to be the window on the bottom of the EventSystem inspector would tell you what you were hovering over and made it easy to debug. Now it's mostly trial and error.

I think it's a URP thing?

[magic temple]

My question here is, Why a prefab is 'enable' that has been answer, thanks you for that

[solar hill]

come again?

[magic temple]

and, why I have acces to my JSON even the Awake of my prefab its not suppose to be activate ?

[naive pawn]

i gave you advice on how to improve your code, and you've been aggressively denying it because it would make performance worse
that's just not how you should be working

[naive pawn]

ive already answered you

[polar acorn]

This is impossible, I can't keep dealing with someone who is belligerent as well as having a language barrier

[naive pawn]

#💻┃code-beginner message

[magic temple]

aggressively ? my excuse, my english its my devil

[magic temple]

Where ? I must have missed it.

[polar acorn]

They linked it

It's the same thing I've said as well. The one that you're loading the JSON on and the one you're trying to read it from are different instances

[magic temple]

Question, they are both in the prefab

[naive pawn]

that's not a question

[magic temple]

Good point

[naive pawn]

you have a Computer prefab (as an asset, in the project) and a Computer prefab instance (in the scene)

both of those each have their own ComputerManager/ComputerTextManager

[polar acorn]

The prefab file and the instance in the scene are not the same object

I cannot stress this enough

They're two different instances

If you do something to one of them, the other one is unaffected

[magic temple]

Im using deepl, hehe

So, Computer, which is cloned on stage and includes my script, the ComputerManager and ComputerTextManager, ComputerManager can have its awake activated, but not ComputerTextManager?

[naive pawn]

no, the ones in your scene are active, the ones in the prefab are not

[magic temple]

... Well, here is, my problem

the core even, My Cloned one say to myself, that he is inactif

and losing his own data

The Cloned one, the one in the scene

[naive pawn]

that's not what happened, no

ive already explained what's most likely happening

[magic temple]

yea and you say that ComputerManager its awake, but not ComputerTextManager

if im correct

[naive pawn]

you are not

i just corrected you

[magic temple]

here ?

[naive pawn]

yes, and in my initial explanation as well

[magic temple]

" right now you have 2 instances of the ComputerManager/ComputerTextManager.

one in the prefab, one created later in the scene, at runtime.

the one created in the scene is handling itself. the ComputerManager.Start coroutine is being executed, ComputerTextManager.Awake is being run, etc.

the prefab one is getting its ComputerManager.Start called separately or something, maybe through Launch (which probably should not exist), there's that weird AutoAssignAssetReferences in Comparator. you definitely don't need anything like that " here ?

[naive pawn]

what else would i be referring to

[zenith cypress]

btw you can use the eventsystem's raycast into a cache list to check that manually (it's not much to do for it). I use that when debugging ui stuff these days in the rare cases I get a blocking 0 alpha sprite and can't find it

[polar acorn]

Good to know! A bit more involved than the old "just look at it" method but definitely useable

[magic temple]

Are you alright ?

I mean, right now Im tired, like, really tired, and if I

if I say someting bad, im sorry

[naive pawn]

i'm irritated because you seem to be intentionally obtuse right now

[magic temple]

Well, its not my objectif

I want just to fix a missunderstanding of mine

Still, thanks you for your time

I will, try to make it not a prefab, or something

My excuse, have a good day

[naive pawn]

sounds like you do want it to be a prefab here, considering you wanted more computers

you just need to treat it correctly

[magic temple]

I Know, I try

But, Im searching how to do it

but im sure I will found out

[old skiff]

why could this code not work

[naive pawn]

you tell us

what's the issue

[old skiff]

its suppost to make you move but i just fly or makeweird movements

[polar acorn]

Try logging w and see if it's doing what you expect

[slender nymph]

did your keyboard stop working partway through naming these variables? or is there some reason they have names like we and w that don't appear to actually mean anything?

[old skiff]

uh well i was lazy and im just testing my skills

[slender nymph]

coding skills including making your code readable

[old skiff]

but it aint working why\

[slender nymph]

try logging some useful information, like digi suggested instead of just logging the word "moving" since that doesn't actually tell you anything

[swift crag]

I don't see any movement happening at all in that example

[old skiff]

nvm i think its because i forgot to make speed higher and rigidbody not get effectedby objects changing it rotation

i mean freese rotation

[dry sun]

When I hit the Space button, why does my word get deleted?

[naive pawn]

press the insert key on your keyboard

it toggles the input mode between insert and replace

[coral crater]

aplogies if this isn't exactly the right channel for this - I'm looking to do something adjacent to A* pathfinding for my game. However, I can't really find a tutorial which covers pathfinding for a non-grid based non-top-down scenario. all I need really is a way for each of these green rectangles the know who their neighbouring rectangles are so they know how to calculate a path towards a destination, e.g. the character is at the red star, and now needs to go to the red cross. Is there an obvious way of setting up a "web" or these neighbouring boxes/grids/waypoints etc? considering the fact that some areas will be more complex and forking than this one

the first thing I thought of when it came to implementing this was to actually create invisible rectangle gameobjectthat do overlap physically, so they can check for a physics overlap to know where their neighbours are when a new path is being looked for, but that sounds kinda resource intensive?

tl;dr, best way to make a custom grid where each component knows what's neighbouring it?

[eternal needle]

You arent creating instances of Listing, yet are trying to access the .product of a listing. You've created the list but not the elements inside

[polar acorn]

Either listing, listing[i], produceHandler, or produceHandler.produce is null

[silk night]

Eh why is that link in here? 😄

[brazen heart]

Does anyone know how I can fix this error? I can't seem to find this option in the inspector

[silk night]

its called Read/Write

[brazen heart]

I found it thx

Ok now instantiating the object itself doesn't seem to work
I've tested that this runs but no object gets instantiated

[slender nymph]

make sure it isn't actually being destroyed immediately because this will instantiate the object

also, I know it isn't a compile error because there's the implicit cast and it will make no difference here, but you probably want to be using UnityEngine.Quaternion rather than Unity.Mathematics.quaternion unless you actually know why you would want to be using the latter rather than the former

[north kiln]

Why are you subtracting 1 from Length when you sample Random?

[brazen heart]

It's zero based right?

If there were only 1 object and I rolled a 1 wouldn't that be outside of the array?

But yeah I got the thing to work

[slender nymph]

yes, but Random.Range with ints is max exclusive so it can never return the second number

[brazen heart]

Oh wait yeah I forgot about that

thx

logic manager:

ok, it lets me run the game now, but i can still flap after death and this error appears:

[slender nymph]

and what is line 27 of Logic.cs

[slender nymph]

then bee is not assigned, make sure you've dragged the reference into the inspector since that variable is serialized

[sweet meadow]

ok

there's no error message now, but it still dosn't work, im guessing i have to specify the object and then the script attached to it?

[slender nymph]

you likely have more than one Logic component in the scene and the other one, which is the one being found with that FindGameObjectWithTag call, doesn't have it assigned. you should do two things here:

1. remove extra Logic components if you only need the one
2. serialize your logic variable and drag the reference in like you've done for these other variables instead of relying on a GameObject.FindXXX call

[tired python]

would something like this work?

colliders having the same layer will def collide with each other

[sweet meadow]

its just this

[slender nymph]

that doesn't change what i said. search the hierarchy using t:Logic and you'll see at least two Logic components in the scene

yes, those are all of the existing layers that you have

[void zodiac]

where would i see whats in each layer doe

sorry im rly new to this

[slender nymph]

look at the object(s) you want to detect and look at what layer you've put them on

[void zodiac]

OMG I SEE IT

TGHANK YOPU*

[slender nymph]

ideally you'd create a new layer specifically for the player and put it on that layer, then only include that layer for your "what is player" layermask

same for ground, really (although this isn't a strict requirement like the above would be)

and you definitely do not want those things on the same layer, otherwise you'll be detecting the ground as the player

[sweet meadow]

how do i make this work? do i say 'if (Collision2D.tag == ("Pipe")' instead?

[slender nymph]

use the compare tag method, not string equality. but also you need to get the tag of the collider/gameObject that is being collided with which the Collision2D object has a reference to

you were so close before when you posted in the wrong channel, you just weren't using the correct method name

[sweet meadow]

how would i write that

[slender nymph]

go back to the code you had before and change it to the correct method name

[void zodiac]

i made 2 layers for player and monster, but it's still not moving

Do i need a layer for monster aswell maybe?

[slender nymph]

what layer is the ground on

i mean the actual object in the scene, not the layermask variable

[void zodiac]

it's on ground it is untagged doe

[slender nymph]

right, so if the ground is on the Ground layer, and you are detecting the player by checking if anything is within range on the Ground layer, which of the three if statements in your Update method do you think is currently true?

[void zodiac]

omg i cant believe i did that

[cosmic dagger]

This looks fine. If using a trigger or collision check, remember to compare the layers

When using the Overlap or Cast methods, use the layer as a filter . . .

[tired python]

why would i want to compare the layers? can't i just use the layer collision matrix to decide which layers should be colliding?

[rancid berry]

hey can someone PLEASE HELP ME ive been on the internet for about some time now about 3 months looking for SOMETHING to help me learn C# and the fact is, theres so much i dont know where to put my time to learn. I was watching sebatian Leauge videos but he goes a bit fast and often i rewatch videos and feel stupid. My name is SirSurf and if anyone can help a beginner that would help. I want to create games in Unity and learn how to do C# so i can later do it as a game dev in the future and this is something that i really want to spend time on so if someone could give me a course because thats what i was looking for before and it was alright and so did videos and i came here to also ask questions about things.... yeah... sorry for the rant.....

[slender nymph]

there are beginner c# courses pinned in this channel

[rancid berry]

i feel so lost

[tired python]

do a beginner c# course

and start coding, not just watching videos

[cosmic dagger]

Only if you use the Cast or Overlap methods bc you can provide a layer(s) as a filter . . .

[rancid berry]

can you reccomend somthing?

[tired python]

check out the pins as @slender nymph suggested

[cosmic dagger]

@tired python Placing GameObjects on a layer does not automatically filter them during collisions . . .

[sweet meadow]

CompareTag dosen't exist??

[slender nymph]

yes it does (provided you call it on the correct type of object)

[sweet meadow]

i call it on 'collider' right?

[tired python]

i think there might be a miscommunication going on, cus i checked this out, and well, the Tower layer does collide with the Enemies layer

maybe you are thinking of a specific scenario or something? i don't quite get it

[slender nymph]

yes, you can call CompareTag on a Collider2D. show your actual code

[cosmic dagger]

If you use trigger or collision methods, comparing layers is the fastest option, TryGetComponent is slower (but still fast) and gives you the component of the object has one . . .

[rancid berry]

can all fundementals of C# be applied in other things? a problem i find is how to use code creativly but i dont think you guys are like a dictionary or google so if you cant answer that its fine

[slender nymph]

several things wrong here, for one, this isn't even attempting to use CompareTag. for two, you are doing this on a Collision2D not a Collider2D. those are different types of objects

[cosmic dagger]

Collision2D does not have a tag property . . .

[sweet meadow]

yea that was the old code

[slender nymph]

yes it does. it's Collision2D that doesn't

[cosmic dagger]

And you didn't even use CompareTag . . .

[tired python]

collision.gameObject.tag i think like in this

[slender nymph]

now go back to the even older code where you asked what you did wrong and it was pointed out you had the wrong method name. then just use the right method name
which is exactly what i already told you to do but you just didn't for some reason

[cosmic dagger]

You're just adding things randomly now. You need to access a field or property that has the CompareTag method . . .

[sweet meadow]

it works now

srry

[cosmic dagger]

What do you mean by "other things? "

[tired python]

why would i need to compare layers, can't i just set the right layers for the right colliders just as is, i don't find the need to compare layers, i just make the child objects and main objects have the right layers from the get go

[sweet meadow]

is there an easy way to check for both collision and trigger enter?

in the same statement

[cosmic dagger]

Yes, because you checked them to collide. I'm not sure why nothing else is checked, though. These are the collisions for all of your objects. Currently, only those two layers will collide with each other; nothing else . . .

[slender nymph]

depends on the use case. if you are referring to the OnTriggerEnter and OnCollisionEnter methods though, those are separate methods.

[tired python]

ya, i don't need most of those checked, i am experimenting still

[sweet meadow]

what i mean is can i check for both simultaniously

[slender nymph]

if your logic is exactly the same in both of them you could just have each of them call the same method though (passing relevant data like the collider entered/collided with)

[slender nymph]

not those methods, no. because, again, they are separate methods. you could use physics queries to check for overlapping colliders and do manual collision checking, but that's a lot of work and the right thing to do depends entirely on what you are actually trying to accomplish

[tired python]

you know what, i will implement what i am tryna do, and then post it to you later, @cosmic dagger

[cosmic dagger]

@tired python No, the layer matrix only determines what objects can collide with each other. Any GameObject with a collider will trigger a collision on another GameObject with a trigger or collision method . . .

[tired python]

given that both of them have the box in common checked out in the layer matrix

[cosmic dagger]

You need a filter to find out if the collided GameObject is the one you are looking for. There are multiple ways to filter . . .

• compare layers
• check Component
• compare tags

Anytime you have a collision, whether using a trigger/collision method, the Cast methods, or the Overlap methods, you need a filter to check the collided object(s) . . .

[tired python]

suppose i have two different GameObjects one of which has a kinematic collider, while the other one has a static collider. If i were to rb.useFullKinematicContacts = true; on the GameObject having the static collider, would it recognise collisions with the GameObject having the kinematic collider?

cus on trying it out, i am having to enable the Use Full Kinematic Collision on the GameObject having the Kinematic collider, and only then is the collision being detected...

said GameObjects in question

[wintry quarry]

Have you read this?

I think it explains it all pretty clearly: https://docs.unity3d.com/ScriptReference/Rigidbody2D-useFullKinematicContacts.html

[slender nymph]

correct. without that setting Kinematic bodies do not collide with static colliders
https://unity.huh.how/physics-messages/collision-matrix-2d

[wintry quarry]

This is only used when the bodyType is set to RigidbodyType2D.Kinematic.

[tired python]

no like i get that, but the setup i had before was one in which both the GameObjects had Kinematic and Static on them, and just having a script attached to the GameObject having the Static rigidbody2D, which had this line rb.useFullKinematicContacts = true; would make them collide with each other

[wintry quarry]

I doubt that, because as the docs say, that property doesn't do anything unless the body is kinematic

[slender nymph]

are you certain that wasn't setting it on the kinematic body?

[tired python]

oh ya, i do remember changing it to static once i found out that static is used for GameObjects which don't move.

and it stopped working after that

[slender nymph]

is there even a specific reason this object has a rigidbody on it if you want it to be static anyway? i get that under very specific circumstances that would be necessary, but it doesn't seem like it is here

[tired python]

ya, remember the dragon trashcan? it detects when a unit is put on its collider and blasts it away

[slender nymph]

what does that have to do with having a static rigidbody?

[tired python]

the dragon don't move

and similarly, the collider doesn't

[slender nymph]

right, which is why i'm asking why it has a rigidbody at all

[tired python]

cus collision checks can't happen with just a collider

[slender nymph]

making the rigidbody static is exactly the same as having no rigidbody when it comes to collision detection

[tired python]

💀

wait, so a GameObject with just a collider in it which is static triggers OnCollisionEnter2D?

[slender nymph]

no, only a dynamic rigidbody will cause those messages

[hot wadi]

I mean, static body is just one without rigidbody

[tired python]

oh, well in that case, the dragon does need the rb cus it has a script attached to it which checks for collision and blasts it away

[slender nymph]

right, but for 2d there is the Static body type which functions exactly the same as having no rigidbody (but with the added benefit of creating the compound collider)

[slender nymph]

but it doesn't need the rigidbody here because the rigidbody is static. the other object is what is causing the OnCollision message to be sent to this object

[tired python]

well, i don't want the other GameObject's script to have more lines of code

[slender nymph]

nobody said that was necessary. all i'm saying is that the static rigidbody on this object is doing literally nothing at all and can be removed

[tired python]

WAIT A SEC

[slender nymph]

and object can still receive a collision message from a dynamic rigidbody even if it doesn't have one itself. it's only the dynamic rigidbody that is actually sending that message

[tired python]

that's srsly trippy

the other gameobject sends the msg to the static gameobject

[slender nymph]

that is how physics messages work, yes

[hot wadi]

If u are talking about trigger, static can still receive it

[tired python]

not talking about trigger

[slender nymph]

that is not in question here. and is, in fact, pretty much what i have been saying this entire time. the dynamic rigidbody is sending the collision message to the static collider

or i guess maybe it's a kinematic body with full contacts enabled. either way though, the non-static body is sending the message to both objects

[tired python]

what if i were to attach the same mechanism to the different scripts, as in, destroy the gameobject, would one destroy the gameobject and then the other return an nre?

naw

aight

oh wait, nvm, it won't work, cus i am already using a collision check to do something else, i would need to check for layer in that case i guess

[sweet meadow]

how would i teleport an object to say, 0 -10 0?

[slender nymph]

assign its transform.position to that

[sweet meadow]

something like this?

[slender nymph]

you should do some beginner c# courses to learn how the language works. there are some excellent ones pinned in this channel

[sweet meadow]

ok

rb.transform.position = new Vector3(0, -10, 0); ?

yippie

[slender nymph]

although if you are doing this for a rigidbody you'd want to set the rigidbody.position rather than the transform's position

you should still go through some beginner c# courses to actually learn how the language works instead of just guessing though

[sweet meadow]

ok, i will

tysm

[tired python]

@slender nymph it does return a nre

[slender nymph]

show exactly where you are getting this NullReferenceException, because a destroyed object doesn't actually become null. so you'd be getting a different error if you were trying to operate on a destroyed object.

[tired python]

static GameObject

void OnCollisionEnter2D(Collision2D collision)
{
    if (collision.gameObject.tag == "UIDroplet")
    {
        Debug.Log("Muahaha");
        Destroy(gameObject);
    }
}```
`Kinematic GameObject`

i am getting the error in the highlighted portion

[slender nymph]

and what is the actual error you receive

[tired python]

NullReferenceException: Object reference not set to an instance of an object

[slender nymph]

also you don't need a coroutine to delay Destroy, it has a second paramter for the delay

[tired python]

i know that, i just wanted to try implementing it for the first time

[slender nymph]

but . . . why? if you know it isn't necessary and that the Destroy call already accounts for a delay, why would you create a coroutine for a delay?
anyway, the NRE is actually likely being caused by the fact that unity will reuse those Collision2D objects

[wintry quarry]

Can you show us the actual full error message you are seeing in the console window?

[tired python]

NullReferenceException: Object reference not set to an instance of an object
UnityEngine.Collision2D.get_gameObject () (at <f1a2e4fe3e024bda9959a5de412d1a5e>:0)
ColliderCollisionCheckScript+<DestroyAfterTime>d__2.MoveNext () (at Assets/Scripts/Collision/ToothlessCollision/ToothlessCollision.cs:28)
UnityEngine.SetupCoroutine.InvokeMoveNext (System.Collections.IEnumerator enumerator, System.IntPtr returnValueAddress) (at <a25ed31d46d841d0bef9ea31576356a5>:0)

this is 28

[wintry quarry]

yeah the NRE is inside the gameObject property getter on the Collision2D object - box is dead-on about this being an issue of tryin gto use Collision2D this way

why don't you just pass the GameObject as the parameter

Collision2D isn't something you should hold onto for a long time

[tired python]

elaborate

[wintry quarry]

likely that Collision2D has been returned the Unity's internal object pool and cleared

[wintry quarry]

elaborate on the proposed solution?

Change to this:
StartCoroutine(DestroyAfterTime(col.gameObject));
and just fix up the DestroyAfterTime coroutine to operate on a GameObject param instead of a Collision2D

[ivory bobcat]

Start the routine with the game objectcs StartCoroutine(whatever.gameObject);Image provided, so I did not bother copying exactly as is.

Where you'd change the definition of the ienumerator function to take a game object instead

[slender nymph]

https://docs.unity3d.com/Manual/class-Physics2DSettings.html
it is reusing the same instance of the Collision2D for every Collision message so it sets the gameObject (and others) propery to null.
you need to pass the GameObject directly to your coroutine not the Collision2D to avoid this

[tired python]

no, as in, what you meant when you said gameObject is a property of whatever col is and that nre is a problem or smth

[wintry quarry]

You have a reference to a Collision2D obejct and you're accessing the .gameObject property on it. The NRE is coming from the property getter, as you can see in your stack trace

[tired python]

aight

oh, but its copy of the object

[wintry quarry]

we don't know the source code for the property getter so we can't tell exactly what the issue is but basically you can't assume that Collision2D object will be valid in 1.5 seconds. It;s only guaranteed to be valid right inside OnCollisionEnter2D

[tired python]

not the actual obj?

[ivory bobcat]

The collision 2d that you receive on collision is being reused by the system internally so it's game object property is set to null after the message event?

[slender nymph]

it's a class so it's a reference to the same object

[wintry quarry]

nope, Collision2D is a class - so you have a reference to it, not a copy.

[tired python]

ok

wait let me digest

something like this?

both of them are different pointers pointing to the same address?

[slender nymph]

yes. that's how reference types work

except they aren't really pointers because that's not a thing you work with in c# (with the exception of unsafe code)

[tired python]

if the gameobject = null it returns a nre?

[wintry quarry]

no, something inside the property getter for the Collision2D's .gameObject property is throwing an NRE.
it's closed source so we don't know exactly what the root cause is.

[tired python]

there are pointers in c# though right?

[slender nymph]

only in unsafe code, yes. references are similar but not quite the same thing

[tired python]

ya, i won't delve into that, i just figured out pointers a couple weeks ago, don't wanna mess up my understanding without having gained a safe enough intuition for pointers

[nimble apex]

i dont think under normal circumstances u get to use it tho

[tired python]

i do a bit of cpp too, that's why...

[ivory bobcat]

C++ also uses references.. C would be a different story.

[tired python]

aren't pointers basically variables which store addresses?

[ivory bobcat]

Right but no one (higher level languages) uses them anymore unless they've got to.

[nimble apex]

C# and C++ is very very different

[ivory bobcat]

Safety generally precedes performance. C++ would have you opt for smart pointers rather than raw pointers

[nimble apex]

u cant treat C# and the workflow same as C++

[tired python]

i don't know nearly enough to even begin to comprehend why that is so, but aight

ok, now the nre is not appearing

[lavish thorn]

I think pointers are useful when you want to handle memory yourself, so with static vs dynamic behaviors

in C# I don't think it's a thing just cuz uhh, well I don't know, I only used pointers for school making weird memory sections

[tired python]

can you maybe give an example as to why it would be problematic to hold?

[slender nymph]

was the error you were just getting not enough of an example?

[ivory bobcat]

I believe they've informed you that the state is constantly changing

[wintry quarry]

This entire discussion has been the example

your error, mainly

[tired python]

ya, it does not produce that error anymore

[slender nymph]

because you're passing the gameobject around now, not the Collision2D

the gameobject was not the problem, it was the Collision2D and whatever it is doing in the property getters

[ivory bobcat]

In programming, we're meant to avoid undefined behavior. Having access to some data that's not guaranteed to be what we think it is after our use case is pretty undefined.

[tired python]

last question, is there an instance where i would want to use a static collider with a rigidbody2D attached to the same GameObject?

[tired python]

the irony is that i predicted that it would be an nre xD

[slender nymph]

can you be more specific about what precisely you are referring to? because that's a pretty normal workflow (assuming by "static collider" you are referring to just a collider because colliders themselves are not static or dynamic)

[slender nymph]

but you predicted it about a different unrelated reason

this had absolutely nothing to do with destroying the object

[tired python]

when and how do people normally use static rigidbodie with collidersattached to them. because you mentioned something along the lines of, what I was doing could have been implemented without using the rigidbody component attached to the GameObject. That gave me a hint as to there might be a situation where you would want to attach a rb to the GameObject. Does that make sense?

[slender nymph]

you are getting your terminology backwards. it was a static rigidbody. the collider is always static because it is not what controls whether it is dynamic, that's the rigidbody.

[tired python]

oh sorry

[slender nymph]

and you almost never need to use a static rigidbody unless you need to create a compound collider (basically treat all child colliders as one big collider) for an object that should never be affected by physics or move

[ivory bobcat]

I think of static colliders as walls or immovable objects. They aren't meant to move.
I think of objects with rigid bodies as objects that should move.
Both would require colliders of some kind.

[slender nymph]

a static rigidbody probably also receives the collision/trigger messages that are sent to child colliders so could probably be useful to make sure those messages are received by a root object

although it does appear that all collider2ds in the scene that don't have an attached rigidbody are all considered attached to the same static rigidbody so if you end up needing to move specific colliders that aren't part of a dynamic or kinematic rigidbody then you should put a static rigidbody on them because it's faster to move that way

https://docs.unity3d.com/6000.3/Documentation/Manual/2d-physics/rigidbody/body-types/static/static-body-type-fundamentals.html

[tired python]

another thing, i have kind of gotten the hang of how to use the Scripting API, but i don't know what the manual is used for

[slender nymph]

as you can see from the manual link i provided, the manual is meant to give information about different concepts

[hot wadi]

Scripting API is coding-specific, Manual is all the other stuff

Some like Addressables are not included in Scripting, so u have to look into Manual

[queen adder]

Do you guys use ScriptableObjects over Singletons?

[grand snow]

We can use pointers when working with unsafe code in c#. We cant have pointers to managed objects safely because they can be relocated at anytime (by the .NET runtime)
There are extra keywords we can use to prevent object relocation but thats getting to off topic for a beginner channel. TLDR we dont use pointers in normal c#

[sour fulcrum]

over? not really. What's an example?

I've sometimes used some singleton-esque scriptableobject stuff in order to reference my content collections accessible statically

[swift crag]

these are two separate ideas!

[sturdy junco]

Hello :,DD

can i ask

how to get the main camera back when accidentally deleted

[gloomy heart]

ctrl + z

[hexed terrace]

this is a code channel, that is not a code question.
just rmb -> add a camera -> set the tag as main camera

[sturdy junco]

oh sorry im just really new in unity TT

[hexed terrace]

It's ok to be new, but, being new to unity doesn't mean you're new to reading and understanding what channel names mean, or mean you can't read channel topics.

[lyric igloo]

my anmation keep geting stuck with each other they like turning to jump to attack to jump to attack and so on how do i fix it? heres movement code https://paste.mod.gg/inhzvxwbljsh/0 (from attack to idle there is no issue)

[wild bloom]

use blend tree

[lyric igloo]

what blend tree is?

[wild bloom]

Simply put, it's something that organizes animations in the Animator when there are a number of animations that are somewhat similar to each other, like running without a weapon, running without a weapon, and light running. You can organize them all in the blend tree. I recommend looking it up.

[lyric igloo]

ok i will do you think it will fix my problem?

[swift crag]

i don't see how a blend tree would help here

[swift crag]

if you're flapping between two states, that means that there are valid transitions in both directions

so if it's flipping between "Jump" and "Attack", look at the transitions between those states

is it possible for both to be valid at the same time?

[lyric igloo]

no cuse for it to move for jump or run its need attack to be worng and for it to go to attack its need to be right

[swift crag]

show the conditions for the "Jump" -> "Attack" transition

[lyric igloo]

i did

[lyric igloo]

here

oh i didnt

wait

[swift crag]

no, you showed the "Run" ->" Attack" transition

[wild bloom]

I'm not sure, but generally I don't speak English, so there might be a slight misunderstanding.

[lyric igloo]

idk you got a good english

[lyric igloo]

now i did

[wild bloom]

really ?

[lyric igloo]

yeah bro look at it not even one typo

[wild bloom]

I understand a little, but I'm better at writing than reading.

[swift crag]

what about that "Any State" transition?

[lyric igloo]

i didnt use it i have to?

[swift crag]

what are the conditions for the "Any State" -> "jump" transition?

[lyric igloo]

oh

[swift crag]

note that this transition does not care if you're attacking

these transitions are legal at the same time:

Any State -> jump
jump -> attack

[lyric igloo]

yess i fixed jumping

you fixed

[wild bloom]

I'm starting to understand a little. I've had many problems like this with the animator, so I've been working with animation using code.

[lyric igloo]

thank you i tried a lot of time and it didnt work i appricate you

[lyric igloo]

what?

[swift crag]

Any State can be tricky to deal with, since it really does allow transitions from any state

Hello, I'm a complete beginner with Unity. I'm trying to work on a project, but unfortunately, I'm stuck on shaders and materials. The problem isn't so much the code itself, but Unity's logic. If someone could come and help me in pm, I would be very grateful. (I don't think I'm that far from figuring it out.)

Hello, what's the best way to make switching between splinecontainers smooth? I asked ChatGPT, this is what I got.

    public IEnumerator SmoothSwitch(SplineContainer oldSc, SplineContainer newSc, bool front, float targetT)
    {
        Transform bogie = front ? frontBogie : rearBogie;
        float currentT = front ? t : rearT;

        Vector3 startPos = oldSc.EvaluatePosition(0, currentT);
        Vector3 startTan = oldSc.EvaluateTangent(0, currentT);

        // approximate distance along old spline to switch
        float switchDistance = Vector3.Distance(startPos, newSc.EvaluatePosition(0, targetT));
        float speed = Mathf.Max(0.01f, Mathf.Abs(tData.currentSpeed));

        float elapsed = 0f;
        float duration = switchDistance / speed;

        while (elapsed < duration)
        {
            elapsed += Time.deltaTime;
            float blend = Mathf.Clamp01(elapsed / duration);

            // pretend moving along old spline
            float simulatedT = Mathf.Lerp(currentT,1, blend);
            bogie.position = oldSc.EvaluatePosition(0, simulatedT);
            Vector3 tan = oldSc.EvaluateTangent(0, simulatedT);
            if (tan != Vector3.zero)
                bogie.right = tan;

            yield return null;
        }

        // snap to new spline
        bogie.position = newSc.EvaluatePosition(0, targetT);
        bogie.right = newSc.EvaluateTangent(0, targetT);

        if (front)
        {
            t = targetT;
            frontSc = newSc;
        }
        else
        {
            rearT = targetT;
            rearSc = newSc;
        }
    }```
it kinda works, but its not real smooth.

[rocky whale]

are the values of x and y in a Vector 2 object always -1,0 or 1 ?

[naive pawn]

no, what makes you think that

[rocky canyon]

float, float, float.. can be any float

[naive pawn]

some apis, or some contexts, might only give those values, but that's a rule of that api, not of Vector2 in general

Vector2 is just 2 floats

a 2d vector

[rocky canyon]

oh (2) yeap.. float float

[rocky whale]

whenever I print the .x and .y i always see -1,0 or 1 depending on if im pressing a key so I thought it would only take on those

[naive pawn]

that's a rule of the thing you're reading the Vector2 from, not of Vector2 itself

consider what would happen if your keyboard were analog or if that input were hooked up to a controller's joystick

[rocky whale]

oh like the triggers on controllers ?

[naive pawn]

sure, those are usually analog iirc

[rocky whale]

ahh ic

ty

[naive pawn]

for axis inputs, the result is often "normalized", in the range 0 to 1
when it's from digital hardware, you get 0 or 1 - no in between values, that's what digital means

-# footnote: there are 2 meanings for normalized, the other applies to entire structs - a normalized Vector2 has a magnitude of 1, etc

[crisp quest]

how can i access that web where i can type my code and send it here ?

[crisp quest]

thanks bud

[wintry quarry]

I would just evaluate the position for both splines at T and interpolate between them.

[vast comet]

alright thanks

[empty cairn]

Is Time.DeltaTime in seconds?

[night raptor]

YES

[naive pawn]

it also helps to think of deltatime in seconds per frame (or per step, per tick etc as you generalize it)

[boreal scarab]

how do i disable this

it annoys me a lot

[swift crag]

this is an annoying one

I've seen it when my objects go flying violently out of bounds

there's no stack trace because the error only shows up when Unity tries to figure out the position of something on the screen

you don't get to see the moment where it went wrong

[rancid berry]

hey does anyone have any solid courses for C# beginner because well im not a kid and when i tried the ones on the front page they didnt really make me feel like I was learning to use C# creativly for games. If someone could help that would be great!

[solar hill]

well if you need a begineer tutorial for c# then its not exactly going to anything flashy or even related to game development that much

you should probably get a basic understanding of the syntax and language before you start applying it in unity

[naive pawn]

there are beginner resources pinned in this channel

[grand snow]

one link is dead

[rancid berry]

yea idk it feels a lil confusing

lowkey might not even bother with coding since im not smart enough yk😅

[solar hill]

well if you want to make games you have to learn coding regardless of how smart you are

[rancid berry]

ik but i have a learning disorder so things overwhelm me quickly and i dont know where to start. its easy for you as a seasoned dev to say " oh just start" when i dont know where to put my time because i feel like it will take me 10+ years to understand the basics and by the time i have that then i wont even want to do what i wanted to do...

[naive pawn]

coding kinda does that regardless of any learning disorders

it's hard to a degree, but it looks way harder than it is

maybe thisll help

(in general) there's 3 major parts to programming:

• Language - The syntax, structure, and paradigm of each language
• Library - The interfaces and utilities that each environment or toolset provides
• Logic - The algorithms to do work at runtime

Logic is almost completely transferrable between each language and environment, you just have to learn the specific Language and Library that you're using
Language is also shared quite a bit between languages

of course, learning 1 part at a time is easier than learning everything at once, which is why tools like scratch or code.org are popular as coding courses for beginners, especially kids, because it only focuses on the Logic aspect

[solar hill]

"a seasoned dev"

im seasoned with salt

im still a beginner all things considered lol and im still learning myself

i also dont know why you would quote "oh just start" when neither I or anybody else here said that, we even showed you explicitly what to start with

Anyways coding at its fundamental level is about problem solving in bite sized chunks, there are thousands of free resources online where you can start doing this

if you have some previous experience coding then thats great, it means adapting to c# should be really fast, but if not you should start with something more lowkey and not unity

code.org in particular is great

[ancient rampart]

how should I go about instantiating and assigning a bunch of different materials onto my prefab?

I have a setup to edit colours, where it uses sharedMaterial so it affects all of the prefabs gameObjects that use the material, but I can't do that if I want multiple instances of the prefab, otherwise it'll affect all of them.

so I'm looking for a solid solution to make it so each prefab has it's own set of materials that I'll be manipulating through code (that would affect all gameobjects using each specific material)

and I know I could just make a list of gameobjects for each material type and then iterate through them but that sounds super clunky and kind of overkill

[timber tide]

Usually that's the idea, yeah

[ancient rampart]

oh, alright lol

it sounded pretty hacky but if that's what the norm is then I guess I'll roll with it

[timber tide]

You can however lessen the iteration if say you want a single variable to modify all instances, meaning you do want to keep some shared parameters between instancing and you can usually do that with global shader parameters

[ancient rampart]

yeah I was hoping for a single variable to change the param in the shader, I just need it to affect all the gameobjects using that material, within the prefab

I was just gonna instantiate the materials, iterate through all gameobjects that I have in lists, assign the newly instantiated material, then edit that materials shader params the same way I initially did

it just seems very overengineered when it initially was just "edit sharedmaterial shader params"

[timber tide]

https://docs.unity3d.com/6000.3/Documentation/Manual/materialvariant-concept.html
You do have these, but more of an editor time concept. I'm actually not entirely sure if that can extend to the runtime but not something I've looked into.

[ancient rampart]

hmm I'll look into those, thank you

[swift crag]

I wouldn't expect those to exist at runtime

much like prefabs

[swift crag]

i believe you can just access the materials property of the prefab's Renderer, which will cause all of the materials to be instantiated

I'm not sure what consequences that'd have in the editor, though

oh, wait, you're talking about making each instance of the prefab unique

[ancient rampart]

yeah

with a set of objects using the same instance of the material

[swift crag]

not making each prefab's material distinct from other prefabs' materials

[ancient rampart]

I can't edit the shader parameters if I did that though

otherwise it'd edit it for every prefab that uses those materials

[swift crag]

you should either:

• access Renderer.materials and then mess with those materials (which will be made unique to the renderer)
• use MaterialPropertyBlock to set specific properties on a specific renderer

[ancient rampart]

access Renderer.materials and then mess with those materials (which will be made unique to the renderer)

this would only edit a single gameobject that uses that material though, which is the main issue I'm running into

[swift crag]

ah, all uses of the material within a single prefab instance

[ancient rampart]

yeah

[swift crag]

that's the important part I missed

[ancient rampart]

like skin tone, hair colour, etc etc

since you can swap parts out, there are a bunch of seperated parts per prefab

[fervent lagoon]

Can i get some assistance with like super basic code? ive been trying to test out this line for like a week and ive went through a bunch of updates and dowloads and it looks like it would work but has two errors that idk how to fix

[timber tide]

i dont see any code

[fervent lagoon]

i didnt send it, i meant if i could vc with someone sometime about it

[sour fulcrum]

nope

[frosty hound]

You should open with your actual question/intention, instead of baiting a response.

We don't have VC in this server. Ask your question, show the code, and people can help if they can.

If it's "super basic" and a "line" , then there's no reason it needs to be a complex issue.

[polar acorn]

Missing semicolon on line 14

[fervent lagoon]

bro wdym lmao

[fervent lagoon]

well its not like one line but yknow

[polar acorn]

Given there's zero information to anyone to actually give a useful solution I figured I'd just give a solution without a question.

One of these days it's actually going to be a semicolon on line 14 and then I can retire

[fervent lagoon]

math

[tulip relic]

Why does my brand new Unity project have compiler errors from an invisible package

[ivory bobcat]

Try restarting Unity

Other than that, they look like collab and version control configuration issues

[tulip relic]

I tried restarting Unity, deleting and rebuilding a project, and clearing my cache. I ended up having to remove "com.unity.collab-proxy" from my manifest entirely and it worked

[pliant lion]

can i slice multiple images at once ?

[charred monolith]

I recommend to Learn with ChatGPT Model 5. it help me Very much. But First, try to learn a Little Bit c# and then with unity. U dont have to know much c#. only how u Write it.

I'm not sure what is wrong with my player that is not moving

I have the new input system and I copied the tutorials source code :D

https://www.youtube.com/watch?v=24-BkpFSZuI

Okay nevermind

I think I should continue the another tutorial i'm doing

the main game

[left path]

But im not sure if these are okay

Looks fine

[crisp quest]

v += Physics.gravity * stepTime;//stepTime = 0.05f, v is vector 3
pos += v * stepTime;//stepTime = 0.05f, v = vector3, grenade pos = pos here

bro what does this means ? i cant understand why and how it is done and what its work
https://paste.mod.gg/eelrfqgkjytj/0 here

explain it please why it has done ?

[sour fulcrum]

where is the code from?

[crisp quest]

its a script of grenade throwing mechanism

it is showing the trajectory of the grenade

[sour fulcrum]

where is the code from?

AI

[frail hawk]

why dont you ask the AI then

[crisp quest]

GUys tell me how can i start using maths in my code ? how can i learn using formulas in my code

[frail hawk]

i think you should learn the c# basics first

it sounds like you are using ai code too much and you don´t know what the code does

[crisp quest]

i know basics but i dont know to use mathematics in unity cuz it is much different that i do in my note book

[hot wadi]

Seems like u are having trouble understanding the operators

[crisp quest]

no , not with operators but mathf and all, because i can do it on my paper but not able to do it in my script

[hot wadi]

It's hard to explain unless u provide more context. Perhaps the full script with the actual implementation of ur function.
And the formula u are trying to implement as well. I think it's best to create a thread in #1390346827005431951 for this type of question.

[dapper egret]

Are scriptable objects a good way of doing eventa to keep everything modular?

[proper apex]

can anyone help me with a script?

[grand snow]

You can try but you need to ensure the same instance remains loaded and used

[dapper egret]

is it tricky or pretty straight forward?

[grand snow]

Its not hard but you are moving the location of the event for little or no benefit

[dapper egret]

because the main problem i have now is since i do multiplayer i cannot have multiple statics of some classes as that would cause alot of problems

[grand snow]

then have the events not be static?

[dapper egret]

yes but then they will need a reference

[grand snow]

If the issue is getting a reference to the object then you just need to improve how you initialize and share dependencies

[dapper egret]

i want to decouple my scripts more

[hot wadi]

U can just say what the problem is

[grand snow]

You can only do that soo much. Things need to depend on what they need to function

anyway i cant comment more when I dont know specifics

[hot wadi]

There are specific design pattern for this purpose. MVC/MVP, factory pattern, etc.

[dapper egret]

for example say i got a main player controller then i have a script thats like the base mechanics of the game,in order for them to talk to each other i will need to do get component on awake to get references to each script since they rely on each other

[grand snow]

Yes, or whatever spawns the player can get a reference then and also initialize the player

e.g. spawn player, init player with player data

[dapper egret]

ah

i see

[grand snow]

You dont have to only stick with Awake/Start...

DI frameworks exist for this reason, they essentially automate the initialisation of objects with dependencies

[dapper egret]

Hmmm never used dependancy injection before

[grand snow]

I would not recommend that just yet

[dapper egret]

ah ok

thx for the info

[neon ivy]

I'm working inside a namespace but I need access to an abstract class from outside of it in my normal project, how do I do that?

[hot wadi]

Can’t u just inherit it like u normally do? Namespace does not restrict access of classes

[neon ivy]

I can't no, it does restrict access

[hot wadi]

Show the abstract class

[neon ivy]

it's just there so this scriptable object can be added into a specific dictionary

[hot wadi]

What is the error it's showing?

[neon ivy]

I think I figured it out xD it's probably the assembly definition stuff, I don't fully understand it

nvm it's not working, I don't get namespaces Dx

[hot wadi]

Idk why u need that namespace. It does not seem to be a standard. U probably can just get rid of that altogether

[neon ivy]

it deals with the graph toolkit package which doesn't work nicely without assembly definitions

[old skiff]

u mean like this

like this?

[neon ivy]

I'm not sure I get your point

[old skiff]

u can access a class from a different script

[neon ivy]

I'm using a namespace and assembly definition

but I can't get the assembly definition to accept my class from outside of it

[old skiff]

oh

[hot wadi]

Ok, what is the exact error it's reporting?

[neon ivy]

well it just doesn't know it's a class

[old skiff]

i checked if there were any references and there are non so i don't think that exists on unity

i could be wrong tho

[neon ivy]

yea it's my own class xD

it's in my assets folder

[old skiff]

import it

in your work

[neon ivy]

that is the issue yes, I don't think you understand the problem.

[old skiff]

i prob dont

atleast i tried

[undone wave]

the EventSystem object that gets created whenever I have UI elements has this property:

How do I access this through code?

The only explanation i could find online was https://docs.unity3d.com/6000.2/Documentation/Manual/UIE-Navigation-Events.html

which is no longer supported

[keen dew]

The editor version isn't supported. It doesn't mean the navigation event. https://docs.unity3d.com/Manual/UIE-Navigation-Events.html

[hot wadi]

Hm, do u have another Assembly Definition inside the same folder of ScriptableData

This could mean a numerous of things, but since u mention assembly, I have to ask

[keen dew]

https://docs.unity3d.com/Packages/com.unity.ugui@2.0/api/UnityEngine.EventSystems.EventSystem.html#UnityEngine_EventSystems_EventSystem_sendNavigationEvents

[neon ivy]

nope

[slender nymph]

Well that's certainly part of the problem. You should read about how assembly definitions work
https://docs.unity3d.com/6000.3/Documentation/Manual/assembly-definition-files.html

[hot wadi]

Yeah, I'm not familiar with this either so I did some experiment.
If the scripts are in different folders with their own .asmdef, u either have to include them in the same assembly folder, or create new assembly for each folder and reference them in each other.

[neon ivy]

yea I read some of the docs and I gave the AEData namespace an assembly definition and added it to the references of the other one.
does this mean that you need an assembly definition to reference classes in other assembly definitions? or is this just the easiest way to do it?

[slender nymph]

Yes, as the docs say custom assemblies (like those created with assembly definitions) can't reference the predefined ones (like Assembly-CSharp)

[neon ivy]

I guess that did fix the errors so far, thanks for the info. the more you know I guess

[old skiff]

is it just me or do some assets not show the material instead show a pink colour, if its just me how do i fix it

[slender nymph]

this is a code channel.
but also https://unity.huh.how/shaders/errors

[mystic crypt]

quick question, i want to update my ‘line drawing’ code from instantiating circles while the mouse is held down (super intensive, looks like shit and i cant find a decent tutorial to interpolate it so theyre super spread out) into a line renderer or any other kind of line drawing substitute. however, ive got other pieces of code that check how many circles have been spawned inside of a hitbox to tell if youve ‘drawn’ inside of that hitbox for long enough and then run the rest of their code, would switching to a line renderer make this impossible (or at the very least alot harder) since im assuming itll all be treated as one hitbox and not many multiple ones?

[frosty hound]

If you want a straight port, you could technically use circles abstractly but instead of being actual circles with colliders they simply are the points that make up the line renderer.

As for tracking within an area, you can count the points inside of an area (there's probably papers online to determine if a point inside a shape). Or go the easy route and iterate through each point and do an overlapcircle call to check for collision on the hitbox and count them up.

[mystic crypt]

you may be underestimating how much of a beginner i am i hardly comprehend a thing you just said

but at least i know there are ways

[frosty hound]

Well, that's the extent I can go with mobile.
