use a MultiTap interaction

[teal ruin]

Do I have to set that up in the Input Action Asset menu thingy or can I use it like a method in code

I'm not really adding any new buttons on the Input Map, I just want to double tap an existing button to do a new thing

[somber nacelle]

that is on your input action. please see the documentation pinned in #🖱️┃input-system to learn how it works

[uncut seal]

Hi,
in school I am working on a group project where we are making a game very much alike Plague Inc. I want to recreate the game's visual effect where, as the number of infected individuals in a country increases, blood drops are accumulated on the country on the map like you can see in this picture. I'm not very experienced with Unity or game making in general. How could this visual effect be achieved? Is it with a shader, by spawning game objects or something else?
Thank you in advance for any answers!

[somber nacelle]

the answer is almost always shaders

[cold parrot]

could be particles + shaders, from the description, in unity 6, probably VFX Graph

[steady bobcat]

Cleverly using masks can let you have the red texture "grow" to fill the whole country (via a custom shader). It can be made for each country and have a gradient to let you control how much of the country is covered by the red effect texture/something else.

but go to #archived-shaders for getting more help

[uncut seal]

Thank you for your help I will look into it before asking for more help 🙂

[slender jasper]

1. Do you guys know how to export a Unity game to the Web (HTML)?

2. And how do you work as a team on the same project? Is there something built into Unity for that?

Or is it just by using version control like GitHub?

[vestal arch]

1. webgl, built-in build system
2. realtime isn't really feasible, version control works yeah

[somber nacelle]

1. build it for the #🌐┃web platform
2. 

[woeful hamlet]

How come my score TMP textbox isn't updating only if I set its text in Start()? If I comment out that line, it works perfectly fine.

private void Start()
{
    scoreDisplay.SetText("0");
}

public void UpdateScore(int score)
{
    Debug.Log("Ding " + score);
    scoreDisplay.SetText(score.ToString());
}```

[naive swallow]

Are you instantiating multiple copies of this object

[hasty plinth]

Hello, today I tried implementing Unity LevelPlay into my project. I tried building the app to see if it works and the build failed with this error:
Resource 'style/BaseUnityGameActivityTheme' not found in AndroidManifest.xml:75,

Following the tutorial I checked Custom Main Manifest and Custom Main Gradle Template but I haven't done anything else with those. The tutorial I followed also included a workaround for an error that popped up, that made me copy paste a gradlew.bat file from the video description.

I know this is not a "code" question but I didn't know which sub-server I should have used instead.

[steady bobcat]

#📱┃mobile <-- But you may have an old outdated android manifest that needs regenerating (backup old one, delete, tick custom manifest again and migrate changes needed back)

[woeful hamlet]

I don't think so. The script is living in a GameLogic object that only gets created once and only holds scripts.

[hasty plinth]

I deleted it, checked the box again and tried to build the app, but I got the same error again. Did I do it wrong? Also If you want we can continue the conversation on the #📱┃mobile channel.

[heady iris]

unless UpdateScore is only called once (before Start runs), I see no reason for it to not work

[woeful hamlet]

It's called via an Event whenever I pick up a collectible. And the debug line shows that the event is working properly.

It's just that only if I have that initial line in Start, the textbox won't ever update. If I comment it out, it works as it should.

[ashen oyster]

Hey, I've been digging through the unity documentation and there doesn't seem to be some sort of line cast that's similar to boxcast (Yes, there's Physics2D.Linecast but that's not what I'm looking for)
I need it like this image below where you define a line (1), cast that in the scene until it hits a collider (4) the cast stops (2) where it intersects with the cube (3).
How can I go about this 🤔

[cosmic rain]

Why not just do a box cast?

[ashen oyster]

It has a thickness to it which is in the way

[languid hound]

Aren't you just looking for a raycast? Maybe I'm misunderstanding

Raycast is the closest to boxcast in functionality

[ashen oyster]

No, because it needs to sweep a certain area, not be 1 ray

[languid hound]

Ohhh I get it now

Yeah I don't think there's much that can help you with that

[cosmic rain]

Why? But anyway there's no such thing as what you're looking for.

[languid hound]

I'm sure you've already tried but can you set the boxcast's width to something like Mathf.Epsilon or just 0?

[cosmic rain]

This might not work reliably if at all.

[languid hound]

Yeah I wouldn't be surprised if it was jank

[cosmic rain]

But setting it to a moderately small value might work

[ashen oyster]

That's what I'm doing now, but 0.001, anything smaller than that and it'll just stop working

[cosmic rain]

And that's not thin enough for you?

[ashen oyster]

No

Needs to be a 1D sized line

[cosmic rain]

I mean, at scales beyond that, physics collision detection becomes extremely unreliable.
I can even imagine a use case you'd need that for.

[vestal arch]

i mean, that's basically what a ray is

[cosmic rain]

They seem to want to cast a ray/line perpendicularly.

[vestal arch]

you want it to "sweep a certain area", but also have that area be "1d", aka, 0 thickness?
that just seems contradicting

[cosmic rain]

Like a 0 thickness box cast.

[ashen oyster]

Yeah, it wouldn't check for area overlap, it would check when the line would first intersect with the collider shape

[vestal arch]

oh so it's a 2d area/casting a 1d line

[ashen oyster]

Essentially yeah

[cosmic rain]

They only thing I can think of is casting many parallel raycasts.

[vestal arch]

what do you need such a thing for?

[steady bobcat]

Yea you could step along doing them untill you get a hit

[proven talon]

How can i make the cubes not demorph

And customers go to an available table?

I'm using rigidbody

[vagrant blade]

The skewing is a result of them being a child of a non-uniform scaled object.

[proven talon]

Can i share the source code here

[leaden ice]

you can but it's not really a code problem

it's a problem of your hierarchy being messed up

[naive swallow]

Put a log in Start and in UpdateScore. Disable collapse in your console if it's enabled. Look at the order things are printed in

[naive swallow]

It's not a code thing

[young yacht]

private void Awake()
{
    if (playerInput == null)
    {
        playerInput = new PlayerInput();
    }
}

private void OnEnable()
{
    playerInput?.Enable();
}

private void OnDisable()
{
    playerInput?.Disable();
}

does anyone know why when i change to the next scene, then come back it gives me this error

Cannot find matching control scheme for Player (all control schemes are already paired to matching devices)

my player is a singleton with playerInput component inside, im using the generated C# class from playerInput as well

[quick token]

you dont need to put the error message into a codeblock lol

[young yacht]

easier to read

[quick token]

not for me

[young yacht]

oh xD

Cannot find matching control scheme for Player (all control schemes are already paired to matching devices)

there you go

[naive swallow]

Is this script on the DDOL object as well? Or is this just an ordinary script in the scene?

[young yacht]

ordinary script in the scene

part of my PlayerController script

my theory is that even tho i have a singleton player it still instantiates another playerInput

then deletes that playerInput

and unity goes to shit

[naive swallow]

Well, yes, that's how it works.

If you have a scene with a DDOL in it, that object gets created every time the scene loads

that's why you have the object destroy itself in start or awake to make it a singleton

[young yacht]

yup thats what im doing

[naive swallow]

So, your error might be on the one that's getting destroyed. However that code works, you might want to move some things into Start instead of awake, so awake has time to self-terminate before other stuff runs

[young yacht]

lemme give it a try

[young yacht]

if i set it on Start() i get a missing reference error

since i also got my onEnable() function

{
    playerInput?.Enable();

    SceneManager.sceneLoaded += OnSceneLoaded;

    JamonDialogue.EnableControls += EnableControls;
    Jamon.EnableControls += EnableControls;
    Jamon.DisableControls += DisableControls;

    playerInput.Player.Shoot.performed += Shoot;
    playerInput.Player.Shoot.canceled += Shoot;

    playerInput.Player.StartRun.performed += StartRun;

    playerInput.Player.Ability.performed += Shift;

    playerInput.Player.Interact.performed += Interact;
}

maybe a null check here would work

[plucky inlet]

did you even set playerInput?

[young yacht]

void Start()
{
    if (playerInput == null)
    {
        playerInput = new PlayerInput();
    }

    cameraShake = playerCamera.GetCinemachineComponent<CinemachineBasicMultiChannelPerlin>();
}

[plucky inlet]

playerInput = new PlayerInput(); or whatever your class name is?

ah k

What line gives you the null error?

[plucky inlet]

Ah i see, you set it in start

[young yacht]

76 which is the playerInput.Player.Shoot...

[plucky inlet]

let get an educational link for you 🙂 https://docs.unity3d.com/6000.0/Documentation/Manual/execution-order.html

[young yacht]

i know dont worry

read the convo

[plucky inlet]

so you know, start is after enable, but still you wonder why you get the null error?

why not set it in Awake()?

[young yacht]

why dont you read the convo

[plucky inlet]

Cause I just jumped in. guess so you took that in consideration and its not for you, sorry then

[naive swallow]

I don't know what all objects you have that are involved in your DDOL

But things that are going to need to run after the object self-terminates need to be in Start. Things that run before should be in Awake or OnEnable

[young yacht]

what about SceneManager.sceneLoaded

[naive swallow]

You said that this script wasn't on the DDOL so changing this script wouldn't make sense

[young yacht]

does it also run before Start()?

i could check if player exists with sceneLoaded

[naive swallow]

Well, if this object exists long enough for sceneLoaded to run, it won't be running Start again

[young yacht]

yea i see

[young yacht]

moved inputs to Start() function, working now

thanks!

[woeful hamlet]

The numbers are the score, the pickups are worth 2 or 10 points.

[naive swallow]

Remember that thing I said about disabling collapse

[woeful hamlet]

Okay, new question, how do I make it not do that?

[tired pecan]

hey, i made this code and sadly it doesnt work as it should or rather as i want it to work. the player should fall after being in the air for some time while jumping even if i dont release the jump button. sadly it does not do that and as long as i hold the jump button it gains height. i debug.loged the whole code every if statement if something gets called infinitly which it shouldnt, ive asked my friends, chatgpt, even reddit and i couldnt find the answer. Help would be much apreciated thanks!

[naive swallow]

So you do have multiple copies of this object

they're each calling Start when created and overwriting the text

[plucky inlet]

so did you log that isgrounded is always returning as you expect it to?

[woeful hamlet]

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

[tired pecan]

yes it returns false when in the air and true when on the ground. after moving left and right this is prolly the only thing that works 🥲

[high ridge]

Does anyone know why my movement buttons work in the editor but not in the build version on android? Im using the on-screen button component

[rigid island]

no ?

🔮

[woeful hamlet]

The UIManager lives in a GameLogic object alongside some other scripts (currently a static SFX Manager, and the ScoreScript), and gets called via Events from the ScoreScript.

[plucky inlet]

And did you expose your values and check them all at once, so you know, whats going on when?

[tired pecan]

how could i do that the best?

[high ridge]

cool thing

[woeful hamlet]

The sound effects play as it should, and the events work, so apparently it's just that the UIManager keeps calling Start() after every update.

[plucky inlet]

There is so much going on in your code, its hard to follow all values in theory. so just expose the once, that affect jumps without moving left right etc. Just see, what happens to your velocity and also make sure to debug the execution order of your script to follow, what all has to be fulfilled to accept the jump button being pressed and adding velocity to your player

[tired pecan]

ok thank you. would it be possible tho to display the values in visual studio using the debugger?

[naive swallow]

This isn't a singleton

You've kind of missed the single most important word in that type declaration

[steady bobcat]

you can inspect and pin things while debugging and also use the [DebuggerDisplay] or ToString to customise whats shown when first inspect a var

[naive swallow]

This is a member variable, which means every instance of this object has its own copy

So, literally nothing is preventingthis object from existing multiple times

[normal nimbus]

Any chance anyone has experience with setting up a gradle template to look to an Azure DevOps artifact feed for Gradle artifacts? I am running into issues.

[woeful hamlet]

Yep, 'static'🤦‍♀️

[naive swallow]

A very important word it turns out

[woeful hamlet]

My bad, I'm still new at this. Thanks for the help^^

[naive swallow]

Nah this is one of those errors that sneaks up on you, took me a while of looking at it to notice myself

[woeful hamlet]

well, hopefully I'll remember it better now^^ Thanks a bunch.

[tired pecan]

i cant find anything suspicous sadly i also spend way to much time on this i spent around 2.5 hours only trying to debug it

[plucky inlet]

haha, 2.5 h is close to nothing that a bug can take of your lifetime 😄

is your velocity increasing? Or is your velocity just staying the same when you hold jump?

[tired pecan]

my velocity goes like this
it starts at -9.81 (gravity) but somehow it moves very fast down to y max falling speed (-26) as soon as i jump the velociy accelerates up until it hits 30.114... this is the velocity it keeps as long as i press the jump button. as soon as i release it it accelerates down to -26 again

[eager fulcrum]

private float CanMakeJump(Vector2Int start, Vector2Int target, float maxJumpPower, float gravity)
{
    Vector2 startPos = new Vector2(start.x + 0.5f, start.y + 0.5f);
    Vector2 targetPos = new Vector2(target.x + 0.5f, target.y + 0.5f);

    float dx = targetPos.x - startPos.x;

Hey, I'm working on a 2D grid game (think Terraria), I want to check if a monster can make jump from point A (start) to B (target).
So I'm calling this function CanMakeJump(monster.gridPos, target.gridPos, maxJumpPower, someGravityValue)
I have no clue if my formula is even right, I'm getting weird results partially because I don't know how to incorporate horizontal velocity which should be based on monster's movementSpeed statistic.

[leaden ice]

YOur description of what you want to happen and what's actually happening here isn't very clear to me

but it looks to me like you're accumulating velocity even while you're grounded (up to the max falling speed)

which is maybe the explanation for what you're seeing?

[tired pecan]

eah maybe but i have no idea how to fix it

[leaden ice]

only accumulate falling velocity while you're in the air

(not grounded)

when you're grounded, set it to 0 or a small negativevalue

A lot of your code is a bit overcomplicated as well, so it's a bit hard to read it

there's also like 3-4 different places where you accumulate gravity velocity

you should really try to consolidate that to 1

it's too confusing and error prone this way

you also weirdly cut off the beginning part of the script so it's hard to tell which variables are member variables etc and what their types are.

[tired pecan]

should i resend the whole code?

[tired pecan]

i dont understand everything neither i copied it from this tutorial: https://www.youtube.com/watch?v=zHSWG05byEc

[leaden ice]

If you don't understand anything and are just copying a tutorial, the answer is to start over or go over everything and copy it accurately

You must have simply made a mistake when copying the code

but the point of a tutorial is to learn and understand

if you're not getting any understanding out of it, the tutorial was a waste of time

[tired pecan]

rewatched and checked my code 3 times i did everything i could i think

[tired pecan]

i did understand a lot of it but not quite everything

[leaden ice]

I just don't think this is a good tutorial for a beginner

the code is way overcomplicated

it's also just... not good quality code

[tired pecan]

yeah but sadly its the only tutorial i found which explains how to make the character accelerate while moving

[leaden ice]

I'm sure hundreds of tutorials do that

[tired pecan]

thats prolly true i just wasnt able to find any

[leaden ice]

Any that use GetAxis or any that use AddForce will do it generally.

Some will also do it without either of those.

[tired pecan]

could i do it using velocity and vector2.lerp?

[leaden ice]

yes

although

Vector2.MoveTowards would be better

and if you only want to do this for the x axis you can just use rb.linearVelocityX and Mathf.MoveTowards

[tired pecan]

yk what im just gonna code a playerController based on the knowledge if learned in combination with rigidbody physics but with code i can understand

i dont want to put anymore time in this code

[wintry gust]

How can I stop my NavMesh Agents from pushing my player's Character Controller? I'm aware I can fix this using a Rigidbody based Character controller, but the project that I'm working on is using built-in Character Controller.

[latent latch]

Character controller should be able to exclude colliders from layers to interact with

[wintry gust]

I don't want to disable collision, I just don't want the character to be pushed.

[latent latch]

Only thing I can think of is just not making the navmesh agent zero out onto your character then

[wintry crescent]

I have a class InspectableType<T> where I'm overriding the == operator.
is this valid code?

        public static bool operator ==(T x, InspectableType<T> y)
        {
            return Compare(x.GetType(), y);
        }

or will this error out on x == null?

my question is - can I run GetType on a null object if that object is of type T that isn't restricted in any way?

[leaden ice]

it will give you an NRE yes

you should do something along the lines of:

if (ReferenceEquals(x, null)) return false;

return Compare(x.GetType(), y);```

[wintry crescent]

thanks! but why ReferenceEquals rather than if (x == null) or if (x is null)?

is there a difference between the 3?

I'm using x is null inside my Compare function

[leaden ice]

I think with no constraints on T, they would all be the same, but ReferenceEquals is just the most explicit in my opinion.

is null is probably identical

[wintry crescent]

cool, thanks!
another question, is there a way to check if the T in

T x```
is the same child class as the T in 
```cs
InspectableType<T> y```
when both are null?

T is an abstract base class, and I want to compare if the classes of the two objects (that happen to be null) are defined as the same child class of T, or different child classes of T

[leaden ice]

When they are null there's no object to check the type of

T and T are always the same compile time type

[wintry crescent]

but the variable that's being passed into the == function, is defined as something, isn't it

it's defined as TChild1 or a TChild2

I want to get what it's defined as, no matter if it's null or not

[leaden ice]

At runtime it might be one of those things but the compiler only knows T

[wintry crescent]

I suppose

[leaden ice]

It depends on the context of this stuff

It's hard to explian without seeing the rest of your code but presumably this code is in some base class and there are subclasses or something that are defining different Ts

in those contexts the T will be whatever you defined it as in each of those contexts

[wintry crescent]

ok, new problem:
I have that exact child class that you correctly predicted I'm doing here

[Preserve]
[Serializable]
public class TutorialStageSelector : InspectableType<TutorialStage>
{
    public TutorialStageSelector(Type t)
        : base(t) { }
}

that's the entire class. How can I enable implicit convertion from InspectableType<TutorialStage> to TutorialStageSelector, without putting anything inside TutorialStageSelector? The reason I don't want to put anything into TutorialStageSelector, is that actually I have like 6 of those selectors with more to come, and I don't want to write the same thing in every single one

I have a function that takes in a TutorialStageSelector, and I call it from a tutorialStage, and I want to pass the argument as a simple this as parameter (I have the implicit conversion inside InspectableType done already)

right now I'm using this silly wrapper on my TutorialStage

public TutorialStageSelector ToSelector()
{
    return new TutorialStageSelector(GetType());
}

that should be implicit

Oops, seems like that's illegal in C#? https://learn.microsoft.com/en-us/dotnet/csharp/misc/cs0553?f1url=%3FappId%3Droslyn%26k%3Dk(CS0553)

[leaden ice]

trying to wrap my brain around this...

What is the code you wish to be able to write that this implict conversion will achieve?

[magic tusk]

I have a quick question about coroutines:
I have class A (MonoBehaviour) that calls StartCoroutine(f())
if A is """destroyed""" (in a way that I am unsure of... my best guess is that the parent GO is destroyed), will this stop f()'s coroutine?

[leaden ice]

The running coroutine is tied to whichever MonoBehaviour StartCoroutine was called on

if that object is destroyed, all coroutines running on it will stop

note it doesn't matter where f() came from. What matters is what StartCoroutine was called on

[magic tusk]

got it, as I suspected

[leaden ice]

if you did a.StartCoroutine(b.f()); it doesn't matter what happens to b, but what happens to a matters

[naive swallow]

I have a lot of delegates and events of different types and parameters, and I want to write a cleanup method that will force unsubscribe everything from it to use during cleanup in case something didn't properly handle itself. My question is, how can I genericise this to where I could do something like ForceUnsubscribeAll(OnConnectionMade)?

public delegate void NoArgumentDelegate();
public static event NoArgumentDelegate OnConnectionMade;
public void ForceUnsubscribeAll()
{
    if (OnConnectionMade != null)
        foreach(System.Delegate d in OnConnectionMade.GetInvocationList())
            OnConnectionMade -= d as NoArgumentDelegate; 
    }

I don't know what types I'd need to pass in and uses as a Generic to make this useable for every event and delegate type. Passing a parameter of type System.Delegate lets me pass in OnConnectionMade, but I can't -= it.

[somber nacelle]

passing the event as a parameter wouldn't modify it properly anyway since delegates are immutable so, much like strings, when you change it a new instance is created. i don't know if you can pass an event as ref but if that is possible you could just assign null to it

[cold parrot]

doesn't OnConnectionMade = null work?

[hexed pecan]

Are you trying to remove only some of the listeners?

[naive swallow]

I don't actually know. I'll give that shot and see. I'm trying to track down some dangling pointer somewhere causing the program to not shut down correctly, I wanted to be thorough while debugging to find the culprit

[naive swallow]

Nah, scorched earth

[hexed pecan]

Then = null should do it 🤔

[naive swallow]

Then I'll give that a go

[somber nacelle]

assigning null is 100% the cleanest way to remove all subscribers from an event

[viral silo]

This seems like a situation where you could use UnityEvent. https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Events.UnityEvent.html

You can pass a single generic type parameter to the delegate

Has a remove all listeners method

[naive swallow]

Nope, most of these delegates have an arbitrary number of arguments, some params, some return void, some return things, some return tuples

[viral silo]

Oh i ser

[naive swallow]

Some of them definitely could, but mixing between the ones that can and the ones that can't would be annoying so I kept them all at the most complex type among them, which has to be event

[viral silo]

Well a tuple would be fine but multiple parameters doesnt work unless you want to wrap them in a struct

What are you designing here

[naive swallow]

It's complicated

It's a slapdash glue between multiple legacy programs in different languages responding to a bunch of data streams that no mortal should ever have had to put in one place

[viral silo]

Thanks, I hate it

🤣

[naive swallow]

Me too, I assure you

[wintry crescent]

Can someone explain how can this debug.log output this text

none of the above are in any way overriden on my script

[leaden ice]

first thing I would do is add a label to this log to be sure this is what we're looking at

[wintry crescent]

this is called from inside awake of a parent object, if it matters

[wintry crescent]

there are no other debug logs if that's what you're asking

[naive swallow]

Does the script have any Unity Message functions that can be toggled with enabled? (Does it have a checkbox next to it in the inspector)

[somber nacelle]

if OnEnable has not yet been called on that object then isActiveAndEnabled will not yet be true

[wintry crescent]

like this?

[wintry crescent]

oh! yea that explains it

absolutely stupid if you ask me

[naive swallow]

Oh, that's interesting. I guess internally, it sets that property in OnEnable

and since Awake runs first, it's not actually been enabled yet

[leaden ice]

interesting

[somber nacelle]

https://github.com/Developer-Notes-Extension/Unity-Notes/discussions/200#discussioncomment-12123302
looks like the docs had a better hint about that at some point

[atomic whale]

is it possible to get a reference to the prefab asset an object was created from? imagine a prefab asset reference it given and I want to check every gameobject if it was created using this asset.

[somber nacelle]

I want to check every gameobject if it was created using this asset
what is the purpose of this?
https://xyproblem.info

[leaden ice]

Only in the editor.

Otherwise you would need to make your own wrapper to do it

[atomic whale]

editor only is fine. how would I do that?

[atomic whale]

I wouldnt call it that tbh. I asked if smth is possible and explained what I want to do. why? why not?

[somber nacelle]

well typically the why informs the how

[leaden ice]

Google Unity prefabutility

[atomic whale]

a prefab asset is given and I want to check if a game object is an instance of it. I dont see how the why would add anything to this. either Unity provides a solution or it doesnt.

[atomic whale]

[thorn ibex]

I'm making a platformer where, in order to have tight turns, I'm using a speed difference system. Here's my Run Function:

        float TargetVel = InputManager.Instance.MoveInput.x * RunMaxSpeed;
        float SpeedDiff = TargetVel - PlayerVel.x;
        

        float RunAccelAmount = (Mathf.Abs(TargetVel) > 0.01f) ? RunAccelRate : RunDecelRate;
        if(Mathf.Abs(TargetVel) < 0.01f && GroundNormal != Vector2.up) { RunAccelAmount = 0; }
        

        float RunVel = Mathf.Pow(Mathf.Abs(SpeedDiff) * RunAccelAmount, VelPower) * Mathf.Sign(SpeedDiff);

        PlayerVel.x += RunVel * Time.fixedDeltaTime;
        PlayerVel.x = Mathf.Clamp(PlayerVel.x, -RunMaxSpeed, RunMaxSpeed);

        RB.AddForce(RunVel * Vector2.right, ForceMode2D.Force);

        if (Mathf.Abs(InputManager.Instance.MoveInput.x) > 0.1f && (InputManager.Instance.MoveInput.x > 0 && !FacingRight || InputManager.Instance.MoveInput.x < 0 && FacingRight)) { Flip(); }
    }```
I'm not quite sure how to update Player Vel so it ONLY reflects the force applied by Run, as it is a Force and not an Impulse. I did this so it is independent from external forces like jump pads

Here is the full script but I don't think it is required for this specific issue: https://scriptbin.xyz/agejahaxas.cs

[somber nacelle]

PlayerVel.x += RunVel * Time.fixedDeltaTime;
well the math is correct for adding the force to the PlayerVel variable, however it won't account for friction or opposing forces so your velocity may not be the same as PlayerVel even when no other forces are being applied with the AddForce method

[thorn ibex]

I'm just not quite sure when to reset PlayerVel

Should I do that during ApplyFriction?

Because otherwise it will surely just compound every frame and just get massive

[somber nacelle]

i mean, yeah you should probably apply your friction to PlayerVel if you are also manually applying friction, but it still won't account for external friction or collisions.
you may want to ask in #⚛️┃physics if there is a better way to handle this

[thorn ibex]

Ohh wait that's actually smart

[thorn ibex]

Because then I can make PlayerVel lerp to 0 constantly, and Run increases it to a positive value, and Friction decreases it to a negative value

I'll try that out RN

[sacred sinew]

Does anybody have good resources to learn the Finite State Machine pattern?

I just can't wrap my head around it

I've seen a ton of tutorials and videos that tackle it in different ways

Be it using enums, base classes or interfaces

I just can't apply it to an actual project

[somber nacelle]

if you've already seen a ton of tutorials tackling the pattern in different ways, then i'm not sure what you are expecting to get out of other people giving you even more tutorials that tackle it in different ways. there are many ways to implement the pattern, you really just need to figure out what your needs are and find an implementation that meets those needs

[sacred sinew]

I guess I'm just overloading myself like this

I should just take a step back and think about it more

[cold parrot]

maybe look at what a state machine actually is in computer science and why it exists there. this should clear up a lot of things.

if you look at the average state machine tutorial you only get a bastardized version of what it actually is

you can also learn from this rather excellently designed implementation https://github.com/dotnet-state-machine/stateless

[sacred sinew]

I'll check that out, thanks

[heady iris]

my own "state machines" are bastardized versions of state machines!

[minor swan]

My general rule is class based state machines for fundamental systems (game stats, menu, etc) and switch statement/if else based state machines for smaller things (individual enemies or objects)

[rain salmon]

I'm trying to get an enemy to do damage over time, and while i was provided code for a DamageOnOverlap (with a circlecolider 2d) anytime the enemy hits the player, it jus kills them. in the debug it doesn't even do enough damage to kill them, but it still happens. https://pastebin.com/xLbnQSXK

[leaden ice]

Add logs in the TakeDamage method with how much damage is being dealt and the health etc

It seems like TakeDamage is the important code, which you haven't shown

[frank hemlock]

i know its off topic but im in a organization and when i open the project nothing shows up can ayone help?

[rigid island]

not a code question

[rain salmon]

i actally did-

[leaden ice]

Not seeing the damage amount logged or the dying part logged

[crimson plaza]

If I await on an async function in Update does it block my update function or no?

[quick token]

i dont think so

[cosmic rain]

Yes it does.

[crimson plaza]

I've had times when I did something similar i.e. block my update function and the entire editor just freezes; I assume it has something to do with receiving an event from every monobehavior before proceeding to the next frame or something?

[cosmic rain]

Unity's main loop is in the main thread. If you block it, the whole game stops. And in the editor I think the player loop is in the editor loop, so it also blocks the editor as well.

[still jungle]

those Update methods are bound to PlayerLoop so i guess they all have return to proceed to next frame Updates

[cosmic rain]

Code executes line by line on one thread. If you block it, the entire program would block(or at least the thread)

[crimson plaza]

Also how would I wait on an async function's results without blocking the update function?

For some context I have an A* pathfinding function that creates an entire grid of objects every time it's called to reset the hValues and I don't want to throw that in update since I think it will take considerable time, so I was thinking of making it async would help

[crimson plaza]

This is what I wanted confirmation on, thanks!

[still jungle]

its more about locking the main thread where everything runs

[cosmic rain]

Either don't wait for it, or wait for it later, when you're sure it has completed the job.

[still jungle]

as dlich said

[crimson plaza]

I was wondering if there was something like in C where you wait on a mutex, i.e. polling an async functino

If it's done then great execute xyz, if not then keep waiting but don't block

Update() {
  bool done = async function done? 
  if (done) {
    do xyz
  }
   if (not done){
    continue;
  }
}

[crimson plaza]

I see; though it feels weird since I assumed that one monobehavior wouldn't block the entire game's update function running

[still jungle]

you can use Jobs for async, so it gets calculated in another free thread

[crimson plaza]

I have a state machine that needs the results of the async function, so I need some way of communicating that the async function is done

[still jungle]

it can be done with Jobs

[crimson plaza]

I will check that out

[still jungle]

scheldue a job in update, then once its completed assign bool value or whatever suits you

[crimson plaza]

a bit bummed that async doens't support that natively(? not sure if jobs is a part of async)

Thanks ReaZ

[crimson plaza]

exciting though I haven't ever used multithreading in unity yet

[still jungle]

async is C# thing, Jobs are multithread way for calculations created by Unity for Unity

you can use async but you have to handle the treads yourself and avoid blocking main thread

[crimson plaza]

yikes, I see. So the job system takes care of this for us then

[still jungle]

https://docs.unity3d.com/Manual/job-system.html

The job system lets you write simple and safe multithreaded code so that your application can use all available CPU cores to execute your code. This can help improve the performance of your application.

[tight prism]

I just ran over this line of code underlined. Somehow cubeindex (which has a value of 0) |= 1 is equal to 0

am i missing something or 0 | 1 is 1

alright my debugger is wrong somehow..

[still jungle]

you can debug log it and check its value

the bitwise operator should return 1 when its 0|1

[tight prism]

yeah just done that, so my vs debugger local values arent correct for some reason

it is 1

which is a big problem for my debugging

[still jungle]

or you just ran first loop where it was 0 and you reading when it is still 0

[cosmic rain]

A mutex in C would block the thread as well. So I'm not sure what you're asking.

You can check if an async task is done or not. Check the Task API.

[still jungle]

since it check next ifs

[tight prism]

nah i made sure that cubeindex is 0 when passing over that line

anyone had visual studio locals incorrect before?

[vestal arch]

you could use a loop for this btw

[still jungle]

well the other guess would be that the first if doesnt execute

and yes you should use 2 to power x for calculations so you are not stuck with tons of ifs

[vestal arch]

from the screenshot, seems like the condition is false

[tight prism]

This code is ripped from somewhere and im just running over it to try to understand it. thanks for the tip though

[vestal arch]

1 << x, not 2**x

(same result yes, but think on bits here, not numbers)

[thick terrace]

if you mean making it async void and using await then no, it won't block, it's just not really a good idea because the next update won't wait for the next one to finish awaiting

[wheat spruce]

What would cubeindex |= 4 do? I've never come across that

[plucky inlet]

[signal moon]

I have a very..... strange problem

i have just reated a variable, bool, like any other

but it keeps switching to false as if something was forcing it to

but, i searched the entire game for refferences and NOTHING is setting it to false, only to true

i commented those mentions that did

And it keeps being false for some reason

funny thing is, i can set it manually during playtime

and it switches

and everything works lol

[plucky inlet]

One might be posting everything as one single line before thinking about what you wanna say... Maybe try to rephrase that with a related piece of code you are having issues with.

Quick check, be sure its not public and set to false in your inspector

[signal moon]

Ok, found that the issue was different. I have clones of all chess pieces in my game, and one actual piece that is not cloned. The non cloned piece works as intended, but the cloned ones do not inherit the variable, even though i have done very similar effects and they did, which is confusing for me

[plucky inlet]

Again, without code (hence the channel name), nothing we can do here

[summer hazel]

Is there a way yet to get Unity 6 working with C#10+ features? I know a few have been backported, but there's a few QoL ones and such that haven't. I imagine the answer is no (outside of using odd workaround hacks/addons like past versions) but figured I'd ask since .NET parity has been "in the works" for ages at this point.

[thick terrace]

nope the compiler is still stuck on C#9

[somber nacelle]

technically you can update the roslyn compiler unity uses to get the syntax sugar features of newer language versions. but you won't get access to anything that requires a newer .net version. it may not be worth the hassle of doing so though because it isn't really supported

[summer hazel]

rip, kinda what I figured. maybe someday

[spark mauve]

Hello everyone
I know this may sound a bit too bold and sudden, but is there anybody who could help me out with my project?

I've only gotten to work with unity a few days ago because my colleagues asked to

I'm not really sure what a collab means

I'm just searching for a person who could hop onto vc so that I could explain ym goal and issue, and so that we could sort things out together

[vestal arch]

collaboration
are you asking for general help, or requesting someone to work on your project with you personally?

[spark mauve]

As there are no guides on the thing I'm trying to make

[vestal arch]

vc's aren't great ways to get/give help

we don't have any here

[spark mauve]

I noticed, but maybe we could still call in private then

Explaining everyhting in text would take too much time

[vestal arch]

we don't support that here; that's also not a great way to get/give help

[spark mauve]

Understood

[vestal arch]

would explaining everything 8 times to different people be faster?

the point of a community support server is to ask and receive help directly in the server, as text. more people will be able to see your question, and maybe respond, than you would get with private help

[spark mauve]

Understood, thanks for the info still

[vestal arch]

your question being in text allows people to give answers after you've asked, and not just while you're present

[spark mauve]

The thing is - I'm really bad with understanding engines
And explanations in text might be way more difficult for me to understand instead of a real-time voice chat

[vestal arch]

back to your issue; you haven't given much info to go off of, so at this point, nobody can help you; you'll need to provide more context as to what you're trying to achieve and what's going wrong
also you maybe want to consider what channel you ask in? from the brief description you gave, #📲┃ui-ux may be a better fit, but can't really say without knowing what the issue is

[vestal arch]

I'm really bad with understanding engines
this sounds like you've given yourself a massive goal. you don't need to understand the entirety of the unity engine for a single feature. focus on the features relevant to what you're trying to achieve, one step at a time

And explanations in text might be way more difficult for me to understand instead of a real-time voice chat
you can always ask for elaboration.
you can also reread text; if you keep asking someone to repeat themselves, eventually they'll get tired lol

[spark mauve]

Long story short - I'm trying to make a UI action system for a dungeon crawler project that we have
For example, right now I'm working on an Attack option.
When you click it, I want the original image to expand and get replaced with a different version of the sprite, while other three options will be replaced with 3 different options of attacks
So far, I've spent 3 days just to figure out how to properly import pixel art to the engine, and managed to make the attack button exapand on click, along with the alternative sprite appearing separately not to overlap the original button YET
However, for some reason, even though the same animations are linked to both sprites, they act differently, which I don't understand

[vestal arch]

ok well im pretty sure this is not a code-specific question at the moment, could you forward that to #💻┃unity-talk and we'll discuss from there

[spark mauve]

To be honest, this work was dumped on me out of nowhere by the guy who's initial and only responsibility was Unity
If being honest, the way our UI is planned to work is not simple if compared to standart menus and so on
And considering the fact that engines are my weakest point in all sorts of things I could do in game dev, I feel really demotivated working on the UX rather than UI itself, or other things I could take better care of, like animations

[swift falcon]

Hi, I want a rectangle rotate on the z "around" a sphere but rotate it like the hammer on getting over it, it's always attach to player

[spark mauve]

So if my case turns out to be too much of a hustle, I'd just refuse to take this responsibility back to the same guy who game it to me out of nowhere, taking on things I can handle or would like to learn

[spark mauve]

Sure

[vestal arch]

(btw i see you typing. discord has a button to forward entire messages, that's what im referring to

well, for future reference, i guess lol)

[spark mauve]

I wanted to add some extra greetings :p

[trim schooner]

Should I set just the eventbus in the Project Settings > Script Execution Order - or is that v bad to do?

If you try using the SEO you'll very quickly run into issues, it's not a good thing to do

It's best to have something that loads/ enables things in the correct order.

Whether this be having a 'manager' scene which loads first, then any other additional scenes additively after.. or a manager in the scene which enables game objects in the correct order... or some other way, I aint going through everything

[sharp temple]

Hey ive got a question, since forever to make a gun ive always used raycast but i was wondering if i made a very fast object that behaved like a bullet, (moves using rigidbody and has a trigger collider) if the player lagged would the bullet go through and object due to its fast speed and not call OnTriggerEnter or would it still call it?

[lean sail]

it wouldnt even matter if the player lags, very fast physics objects wont always behave as expected. you'll probably have objects go through each other without calling the physics methods

[sharp temple]

Sad

Even if i set collision detection to continuous dynamic?

[sharp temple]

So id have to do a boxcast then to check

[leaden ice]

"lagging" is kinda meaningless here. Unity uses a fixed timestep physics simulation

It will always do the same number of physics simulation steps

Continuous detection would help for actual collisions not for triggers

[sharp temple]

Okay

So if my bullet’s collider isnt a trigger it would work fine even if it has very fast speed

I assume?

[leaden ice]

Continuous detection works only so well. At a certain point you'll need to do Raycasts regardless

Reducing timestep can help too

[leaden solstice]

Also trigger events are not affected by collision options

[sharp temple]

Yeah but I wonder how could I check because a raycast wouldnt be accurate

I would need a box cast or something

But if it moves downwards and forward then it wont replicate like it should

[leaden ice]

Yes sure, SphereCast

Whatever shape your thing is

Wdym by that

[sharp temple]

Yeah but so i would put it in fixed update but then how would i scale it

[leaden ice]

Wdym scale it

[sharp temple]

Like I would need to scale it by the speed and by Time.fixedDeltaTime no?

[sharp temple]

Scale the spherecast?

Lets say in one fixed update it moved 100 units

[leaden ice]

You mean the distance? Yes it would be velocity * fixedDeltaTime

[sharp temple]

Yeah but like how do I interpret it in the code

It wouldnt be as accurate tho

[leaden ice]

No idea what you mean by that

That's pretty much the code right there

[sharp temple]

If it moves in two direction

[leaden ice]

It can only move in one direction

rb.velocity

[sharp temple]

What I mean is like it moved forward + little to the right + little to the left

I would need to start the spherecast from the old position

And finish it at the current position

[leaden ice]

That's just the velocity

You're overthinking it

That's one direction

[sharp temple]

That would make a sphere cast that is the size of the general direction

No?

[leaden ice]

Huh

[sharp temple]

It wont be accurate

[leaden ice]

I think you're confused about what SphereCast does

[sharp temple]

It casts a sphere

[leaden ice]

Yes

[sharp temple]

With a radius

[leaden ice]

The radius is just the radius of the bullet

[sharp temple]

Yeah so how can I check with that properly

For objects that were behind

Like a for loop?

[leaden ice]

You don't need a loop

Just one cast per FixedUpdate

Along the path the bullet moved

Or will move

[sharp temple]

Yeah but the sphere wont necessarily cover the whole distance it traveled

Cuz its a sphere

[leaden ice]

Of course it will

Because you control exactly how far it covers

[sharp temple]

Or maybe im just too dumb to understand what ur trying to say
.

If u dont mind can u do an exemple code?

Like idk pseudo code

[leaden ice]

I did right here

[sharp temple]

Yeah but that is the value for what?

Like in what fonction would u use it

[leaden ice]

Direction= velocity
Distance = velocity.magnitude * fixedDeltaTime

SphereCast

[sharp temple]

Ok but what parameter

[leaden ice]

Direction and max distance

[sharp temple]

There is max distance in spherecast?

So like the radius?

[leaden ice]

Yes

Of course

No

Radius is radius

That's separate

Again I think you're not understanding what SphereCast does

[sharp temple]

Ok can u write the whole function so like SphereCast(oldPos, radius, distance etc

[vestal arch]

sphere is sphere + cast

[leaden ice]

No I'm on my phone

[vestal arch]

radius controls how large the sphere is

[leaden ice]

But I gave you all the parameters

[vestal arch]

distance controls how far the sphere goes

[sharp temple]

Ah me 2 😔

[leaden solstice]

Read documentation

[lean sail]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Physics.SphereCast.html

[vestal arch]

a spherecast draws out a capsule

[sharp temple]

Really?

Then why does CapsuleCast or wtv exists?

[vestal arch]

because capsulecast casts a capsule

it doesn't draw out a capsule

[sharp temple]

Oh I just understood

[vestal arch]

you can get like, a rounded rectangular prism with a capsulecast

[sharp temple]

So like it checks the sphere and the distance it traveled

Like if it checked a lot of spheres along the path

I didnt know it could do that

[vestal arch]

it doesn't check a lot of spheres, really

[sharp temple]

Yeah idk the math behind it

[vestal arch]

yeah me neither

[sharp temple]

But uh this is how i will interpret it

Alright nice

Now i know how to implement well a bullet

Now I can use the trail system too nice

Also I hope we can get more control over how lighting works in hdrp cuz like i wanna illuminate a big space without most of the room being completely white due to the light being strong

There should be a maxIntensity or something on the light component

[sharp temple]

Thanks

[vestal arch]

#archived-lighting could help with that

[sharp temple]

Ive already asked before and i dont think there was a solution

The problem is over exposure

I liked how the default rp handled lighting

An object could never be very brightned / over exposed

But urp and hdrp dont have that sadly

Or i dont think they have

[vestal arch]

yeah idk but if there is you're not gonna get it in this channel lol

[sharp temple]

Yeah ima ask in lighting

[rain salmon]

could someone help me with this? still have no clue whats going on

enemy code https://pastebin.com/VcUJ2Xff
health code https://pastebin.com/EtAJViff

[trim schooner]

Add logs in the TakeDamage method with how much damage is being dealt and the health etc

[rain salmon]

my logs shows how much is left after the attack

[trim schooner]

but not how much dmg is being done

[leaden ice]

Nor when and why the Destroy is happening. I asked this earlier...

[rain salmon]

sorry blue, i fell asleep

[trim schooner]

The logs there say you've got 90 hp left, yet it still gets destroyed?

[rain salmon]

yes

[leaden ice]

The logs need to go here

https://pastebin.com/EtAJViff

One in Kill

One in TakeDamage with the damage amount and health before and after

[trim schooner]

You'll maybe have something else calling Kill(); - does this method really need to be public?

[leaden ice]

Very possible something else besides this script entirely is destroying the player. Adding the logs will tell us that if we don't see Kill being called

[rain salmon]

adding a debug line now makes it work??? wuh??

the health counts up though, not down in the debug

that worked tho, thanks

[trim schooner]

20 -> 10 -> 0 is down

[simple ridge]

Hi all, I am working on a project with a cell grid, each cell is represented as an enum:

Dirt, Stone, Water...

A seperate part of my project checks collections of these cells for patterns (say if the cells within a specific bounds are stone or dirt next to water).
The need for OR'ing the enum with these pattern checks made me swap to a flagging system so that I can check if the cell is within the pattern.

That said, this has now had the result that areas (like with world generation) where I would only ever want a single cell to be represented as single cell could now in theory be both Dirt and Stone.

Is their a clean and non-intensive solution for mandating the "flagibility" of an enum depending on context?

[vestal arch]

so is each type mutually exclusive with others?

or is it a mix between some being mutually exclusive and some not?

[simple ridge]

In the context of world generation a cell can only be exclusive (Dirt) for example.
However, I'm using a type of pattern checking over groupings of cells, this is in 3D but a 1D example could be:

[ Dirt | Grass ],[ Air ],[ Air ],[ Air ]

So the idea would be that if either dirt or grass has air above it for 3 cells it will be true

The flag logic is being used here

These patterns can get alot more complicated, but this is an easy example

[vestal arch]

you could have 2 ways of representing types. one as a property, one as a mask

[silver scroll]

Guys were can I ask for people to help on a project?

[vestal arch]

the property way would be 0,1,2 etc, used for tiles, while the mask way would be a bitfield

Like 2 enums? One with [Flag] and the other without?

[vestal arch]

no, just a single enum

the enum would have values 0,1,2, etc
then when you make it into a mask, you would do 1 << type to get a bitmask

[simple ridge]

Oh, so manually doing the mask?

[vestal arch]

you could then check if some tileType (enum) matches some tileTypeMask (bitfield) with tileTypeMask & 1 << (int)tileType != 0

[vestal arch]

well, not manually, but dynamically from the enum values rather than as the enum value itself

[simple ridge]

Right, gotcha. I guess this goes to second question then, do you know if the enum fields for the editor (scriptable objects and such) support bitfields, or will I need to write my own dropdown?

[vestal arch]

well if you use an enum type it'd let you choose from the enums

there is LayerMask that lets you choose a bitfield though, so maybe there's a built-in way? i'll have to do so digging

https://docs.unity3d.com/ScriptReference/UIElements.MaskField.html

[simple ridge]

Thank you, I'll see if I can find anything out about it!

[vestal arch]

i think it's that

[simple ridge]

Oh!

Perfect! XD

Thank you

[vestal arch]

LayerMaskField extends that

So,,, I need some help here sorting out/rubber ducking the logic on the Compendium system in my program. I'm just not sure if I'm doing it in the most optimal or correct way and need some guidance. I'm working on a Compendium of user content, such as Items, Classes, Races, etc— the Compendium class has three Lists, of the three different types of classes it contains: Sources, Entries and Features. I'll deal with the features in the future, right now I still need help with the entries and sources

• Sources are the top-level compendium "pack" of content entries. For instance, a player might have the LaserLlama Homebrew Pack which includes 5 classes, 18 subclasses, 2 races, 40 spells. The source class has very simple parameters— name, ID, author, version, cover art, etc
• Entries are the "meat" of the compendium: There is a class called Entry with some basic info such as name, ID, version, etc. From this Entry class, you derive dozens of specific child classes (Races, Classes, Weapons, etc).

Each GameManager has one Compendium, which is meant to store all the classes and entries and be assessed through different codes in the game every time the game wants to know all the races the player has, all the classes, all the this and thats. Sure. Here's the thing: GameManager has to contain both Sources AND Entries. But logically, Entries are contained in Sources. As in, one Source has many Entries within it. My first thought was to give each Source a List<Entries>, but I didn't like that— for two reasons. First, it would be a nightmare to assess every item or race in the game having to loop through each Source in the GameManager and looking for each Entry in Entry<List> then checking if said Entry is of type Race or Item... you know, convoluted. Second, for some other reasons that I'm not going to explain right now, I kinda need each entry to be parsed into its own separate individual Json at the end when loading so users can share them amongst themselves.

(Continuing)

Then, I had a different approach— each Entry would have a public Source source variable that loads their source within them. At different times the script would loop through all the entries to see if their Source matched the Source in GameManager.Compendium to like, group them by source. But,,, I don't know, it didn't feel right. I don't think the Entry class should hold a local variable with so much information pertaining to some whole other thing— because now you have the fields Entry.Source.sourceName, Entry.Source.sourceID, and even stuff like the cover art— having each entry have to carry a separate local variable for their source's cover art sounds like taking so many resources to allocate for something redundant.

Then my other idea was... give each entry a Source source variable, make it non-serializable, and also a source ID variable. You just store the source ID in the json, and when the entries get loaded, the parser will look through the sources that have already loaded in GameManager, find the source that matches their source ID, and have the Source source = sourceInTheGameManagerThatMatchesSourceID.

This solved my problem with saving all the source's information in the entry's JSON, but I still don't think it helped me with the local variables problem... and overall, this Entry-Contains-The-Source approach is feeling pretty sloppy on my end. I don't know. I don't think I'm doing the right thing.

Does anyone have any ideas of a better implementation of this whole "Compendium contains sources and entries, sources are things that will contain entries" system? Or hell, what should I do in scrapping this whole direction for a more elegant solution that's just not clear to me at the moment? Gosh, and this is all before I implement the features, which are things each Entry will contain... 😵‍💫

[plucky inlet]

I wonder if you could shrink your actual question down to a shorter version. Its just too much to actually get what you really want. At least I found barely time to read and think through all of that, which might have been hours for you and cant be seconds/minutes for us here to follow

[dark salmon]

True. I'll trim it down, hold on 😭 perhaps ChatGPT can summarize it for me rq

I need help sorting out the logic for my Compendium system. The Compendium stores user content like Classes, Races, and Items. It has three lists: Sources, Entries, and Features (but I'm only focusing on Sources and Entries for now).

• Sources are "packs" of content (e.g., a homebrew pack with multiple entries). They store metadata like name, ID, author, version, and cover art.
• Entries are the actual content (e.g., Classes, Races, Items), derived from a base Entry class.
  Each GameManager has one Compendium, which contains both Sources and Entries. Logically, Entries belong to Sources, but I need a way to store and access them efficiently.

Approaches I’ve considered but am unsure about:

• Sources contain a List<Entry> – This makes retrieval inefficient since I'd have to loop through each Source to find Entries of a specific type. Also, for the needs of this project, I need each Entry to be a separate standalone JSON file at the user's drive
• Entries store a Source variable – This feels redundant because each Entry ends up storing full Source data (like cover art), which seems like wasted resources.
• Entries store only a sourceID, then use to copy the Source from the GameManager’s Source list at runtime – This avoids redundant data in JSON but still feels sloppy.
  I feel like I’m missing a more elegant way to structure this. Any ideas on a better approach, or should I rethink my whole system? (And this is before I even add Features, which Entries will contain…) 😵‍💫

Ok yeah this was a decent summary thanks mr. GPT 😭

[latent latch]

Scriptable objects

[plucky inlet]

Only almost my full screen height, great job 😄 😉 Okay, nevermind, lets figure this out. From what I read now, first thing coming to my mind with minimal complexity in structure is your actual list of IDs. So each entry has its ID and your source pack just holds the ID to those entries. Nothing wrong with that

[rigid island]

Dictionary ?

[latent latch]

Dictionary

[rigid island]

ayo

[dark salmon]

Hmmmm so,,, Each entry has an individual ID, and the Source class has a List<string> of IDs?

[plucky inlet]

It really depends on what you want to do with it at runtime. generate the full data set out of this list once or access them frequently or shift the list around change it?

[latent latch]

Really just need to group things out a bit more if you do want to use lists otherwise. You can always have like a primary list, but then group out types into sublists of specific types

[dark salmon]

Generate the full data set once, or minimally if the player makes a new race/class/item/whatever. It shouldnt happen often. In most runtime sessions it would just be

1. Game loads everything from user data, save them to GameManager.Compendium
2. Every time the game needs a list of all the classes, races, weapons, whatevers that the user has saved they'll communicate with GameManager.Compendium

[dark salmon]

mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm quite wise ,,,

[plucky inlet]

So your Compendium is like a growing one for one player locally, right?

[dark salmon]

This is making me think of a bit of a loop actually,,,,,,,, that could be quite nice to me

• Sources have a List<string> EntryIDs which is empty by default
• Entries have a string SourceID, which is always set to the source that's meant to contain that entry
• At runtime start, the game loads all Entries first
• Also at runtime start, the game populates EntryIDs with the ID of every entry who's SourceID matches the source's ID string

I think this way is quite nice actually so the source has a list of everything it contains but doesnt need to hold them in the JSON or anything and its just stored as short strings!! This is a pretty good idea

[dark salmon]

mhm!

This is meant to be a D&D character sheet builder. Your compendium is, metaphorically, your IRL book shelf. You buy books and you put them on your shelf and now you "have" those races and classes to use in your character, but you're not meant to be constantly buying and removing and ripping out pages and rewriting stuff

[plucky inlet]

okay, nice mechanic. Yeh, I really would let the data sets be their own little parts and the compendium is basically just an id holder for all those types

[dark salmon]

Also, yes methinks I need to study dictionaries more they seem very helpful but I'm not super knowledgeable on them

[latent latch]

If a key is an ID/String, usually you do some sort of hash table

but I can't really make too much sense of what you're asking otherwise haha

[hexed pecan]

Dictionary is a hash table in C#

[flint dagger]

Does anyone know how to use blazebin on mobile it just looks like this when I try to scroll down

[hexed pecan]

I have the same issue on mobile. It goes blank when I try to scroll.

[naive swallow]

Yeah it just straight up doesn't work, even in desktop compatibility mode

[rain junco]

i just started my new unity project from yesterday, all pink xD what to do?

idk if its because of the editor, i tried installijng the update, but it says cant uninstall all files or some

[leaden ice]

Upgrade your materials to whatever render pipeline you switched to

[rain junco]

nvm it worked

[rain junco]

everything was pink, even unity itself, whole screen was pink idk why

but thx ;0

now my camera is idk doing weird

[wintry crescent]

is there a nice, easy and simple way to bring all variables on an object to default, without breaking references to said object?

you know, that might actually be a bad solution to my problem, nevermind

[grave vine]

guys i made a func it works but when i spam the fov goes to like 60 like it messes up. Here is the code:

public void ChangeFOV(float newFOV)
{
    if (Camera.main.fieldOfView == newFOV) return;
    targetFOV += newFOV;
    StopCoroutine("SmoothCamTransation");
    StartCoroutine(SmoothCamTransation());
}

private IEnumerator SmoothCamTransation()
{
    t = 0f;
    while (Camera.main.fieldOfView != targetFOV)
    {
        t += Time.deltaTime;
        Camera.main.fieldOfView = Mathf.Lerp(Camera.main.fieldOfView, targetFOV, t / 24);
        Debug.Log(targetFOV);

        if (Mathf.Abs(Camera.main.fieldOfView - targetFOV) < 0.1f)
        {
            Camera.main.fieldOfView = targetFOV;
            break;
        }
        yield return null;
    }
}

[wintry crescent]

targetFOV += newFOV; you sure you want += there instead of just a plain =

[grave vine]

idk why?

[wintry crescent]

because it'll keep growing infinitely every time you call ChangeFOV

you add newFOV to targetFOV rather than setting it

[grave vine]

lemme use = then ill try

[wintry crescent]

also cache your startFOV before your while loop, and use it as the first value in your lerp

[grave vine]

oh i remembered why i did that

imagine it that u use zoom button and running at the same time

cuz u are started to run at the last time

even tho u

zoom

it doesnt work

[grave vine]

why?

bro like im trying to make this thing for 5 or 6 hours bro

like insane

and i still cant

i really need help xd

[wintry crescent]

I mean it seems like you want the zoom to happen over 24 seconds considering you divide t over 24, but using that camera.main.fieldOfView instead of a cached value makes it go much faster than you'd expect

and you can't really predict how fast it'll be going

you have no control over the precise time of the change

you should cache it and then devide over the amount of seconds you want it to last

[grave vine]

idk how to use startfov because it will be so messy like imagine that u use zoom and run at the same time then which one will be start fov

u know what i mean?

[wintry crescent]

divide*
not devide

[grave vine]

how should i do startfov thing

can u pls help me

[wintry crescent]

actually I think lerp isn't what you should use in your scenario

[grave vine]

everyone was using lerp for it

[wintry crescent]

try Mathf.MoveTowards and define a speed of the change

[grave vine]

and why?

[wintry crescent]

if you want to move between multiple values at any time, this allows for a smooth change from any value to any value at constant speed

your current code is not very predictable in terms of speed, and even a correct lerp would make the different zooms look faster or slower depending on how big each change would be

since with a lerp you define a time of the change

and with moveTowards you define speed

it should look better

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Mathf.MoveTowards.html check this page out

Camera.main.fieldOfView = Mathf.Lerp(Camera.main.fieldOfView, targetFOV, mySpeedFOVPerSecond * Time.deltaTime); or sth like that

and you don't need any startFOVs or anythin

[grave vine]

but u use here lerp

[pliant trout]

help i cant refernce my player

[rigid island]

hmm why not

[pliant trout]

look

[rigid island]

so do you have Player component on Player ?

[pliant trout]

wydm

[rigid island]

btw this is a #💻┃code-beginner question next time.
Your Field is expecting a Player component.
The gameobject you're dragg into it does not have such component

If you're following a tutorial I would revisit it because you probably put it on the wrong object

[pliant trout]

👍

[pliant trout]

Thank you i forgot to put the componet on player instead of playervisual

[unreal notch]

Hey having a simple problem, not sure why it isn't working as intended
for context, this script is on a child object with a ParticleSystem component set to Stop action : Callback
I want to delete the parent object when the system is finished

public class ParticleSystemCallbackDIE : MonoBehaviour
{
    private void OnParticleSystemStopped()
    {
        Destroy(transform.parent.gameObject);
    }
}

This is resulting in the object the script is on being destroyed, instead of its parent

[rigid island]

does it work if you put it on the parent?

[unreal notch]

no, because the particle system is on the child

[rigid island]

ohh its on the same object?

[unreal notch]

yea

[rigid island]

you sure all the particles died?

[unreal notch]

yes, because the OnParticleSystemStopped() is happening, its just destroying the wrong object

[rigid island]

ohh so it is working

mb I misread as its not calling it

[unreal notch]

I want it to destroy FirePillar

but it is destroying FireParticleSystemForShader instead

[rigid island]

and the script is on hitbox?

[unreal notch]

no, its on the bottom most child

with the particle system

[rigid island]

its on FireParticleSystemForShader?

[unreal notch]

yes

[rigid island]

why not just make a Serialized reference

[swift falcon]

Try Destroying parent.parent.gameObject?

[rigid island]

probably but thats still ugly

[SerializeField] private Transform thingToDestroy

[swift falcon]

Yeah this is best. Just this

[rigid island]

link it in the inspector so its not sketchy

[swift falcon]

Could be GameObject as well. Transform isn't the important part

[rigid island]

true Im just used to always using Transform when no other components exists

[unreal notch]

hmm, I guess I could seralize it, thats just kinda messy
and I want to be able to reuse the script in alot of different places

I'm pretty sure I solved this before, but I cannot remember how for the life of me

[rigid island]

hows that more messy than doing a bunch of guess working accessing parents

[unreal notch]

cause its not guess work if the prefab is correctly set up

[rigid island]

if you ever change the heriarchy or order in anyway your whole thing breaks

thats the definition of mess

[unreal notch]

yup, but I dont plan to
parent > children hold particles and hitboxes etc
I'm consistent with that

[rigid island]

plugged reference directly, unless its deleted will not care which object its on

i mean its ur project you can do whatever. In the long run it just makes these very sketch at scale

just offering suggestion

<- years learning the hardway

[swift falcon]

Although in this case having a restraint helps make sure we're actually deleting the object the script is on. If you link an unrelated object you're not gonna delete the scripted object.

[swift falcon]

You could put the script on FirePillar and then have it operate on the child, and then just destroy itself OnParticleSystemStopped

[unreal notch]

the problem with that is OnParticleSystemStopped only checks the object its on for a particle system
it doesn't recognize that the system is on a child

but, I just gave up and serialized it, that works well enough I guess

thank you for the help

[night harness]

Anyone have experience in Unity struggling to consistency save generic ScriptableObjects? I was under the impression this can be avoided if you explicitly define them in a class but that doesn't seem to be helping. Currently I have

WeightedManifest : ScriptableObject

WeightedManifest<T> : ScriptableObject
[SerializeField] private Dictionary<T, int> weightedCollection

WeightedStringManifest : WeightedManifest<string>

But sometimes it seems Unity just gives up on preserving the SO's made from WeightedStringManifest and they lose their monoscript reference and all references to them are removed

[latent latch]

WeightedStringManifest : WeightedManifest<string>

That should serialize like any other class

Actually, is string a good enough constraint?

I would assume so

The only time I really run into serialization breaking is dealing with SerializableReferences and serializing by interfaces and stuff like that, but otherwise I've not an issue with explicit constraints

[night harness]

Yeah I thought this was cool to do

Admittedly that dict is actually a serialised dictionary from something on the asset store but the fact the SO completely loses it’s monoscript reference makes me feel like that’s not relevant here

[latent latch]

that would be the problem and one of the reasons I don't use them

[night harness]

I don’t see how that would be the problem here?

[latent latch]

[SerializeField] private Dictionary<T, int> weightedCollection```
This is the only thing there that I can see being a problem, but otherwise the class prototype is fine and shouldn't be the problem

[night harness]

Sure but at best that should just fuck up the serialization of that field no?

The entire SO is failing

[hexed pecan]

How are you creating the SOs?

[night harness]

createassetmenu

each defined class is in it's own monoscript file too cuz i was worried about that being a problem

[cold parrot]

could you maybe share the whole thing, this is just shooting in the dark otherwise

[night harness]

forsure

WeightedManifest.cs

public abstract class WeightedManifest : ScriptableObject
{
    public abstract void ResetManifest();
}

public class WeightedManifest<T> : WeightedManifest
{
    [SerializeField] private SerializedDictionary<T, int> weightedCollection = new SerializedDictionary<T, int>();

    [SerializeField] private SerializedDictionary<T, int> availableCollection = new SerializedDictionary<T, int>();

    //Awful btw
    public T SelectRandom(bool claimSelection = false)
    {
        T randomSelection = Utilities.GetWeightedRandomSelection(availableCollection);
        if (claimSelection)
            availableCollection.Remove(randomSelection);
        return (randomSelection);
    }


    public override void ResetManifest()
    {
        Debug.Log("Resetting Manifest: " + name);
        availableCollection = new SerializedDictionary<T, int>(weightedCollection);
    }
}

[noble herald]

what is causing this error exactly?

[cosmic rain]

It says right in the error: failed to copy a files since it was being accessed by another process.

[noble herald]

but I cant figure out.... how exactly is that being accessed if I restarted Unity entirely and it still errors?

[simple egret]

Do you have the standalone (built) game running? If not, looks like you have a dangling open file stream, restarting your computer should solve it

[noble herald]

probably just running in background somewhere even though I dont see it in Task Manager

[simple egret]

Try to delete the DLL file manually from the explorer. If you're lucky, Windows will tell you which program is locking it

[cosmic rain]

There was a way to find that out via command line and process id. I don't remember exactly, so you'll need to look it up. If restarting doesn't help.

[simple egret]

Resource monitor can do that: https://thegeekpage.com/how-to-find-out-which-process-is-locking-a-file-or-folder-in-windows-10/

[noble herald]

but its closed D:

oh nvm it isn't.... huh????

ok we're good now idk wtf that was

[night harness]

still would love help with this if anyone knows anything

[eager fulcrum]

Hey, any ideas why my AI behaves in such a weird way? I don't understand why it jumps like that and sometimes flips in place a few times.
https://pastebin.com/tK3GuPbz

[rigid island]

are you remaking terraria ? 😮

[eager fulcrum]

not really, terraria is huge

[rigid island]

oh.. gives terraria vibes lol

[eager fulcrum]

I mean, its a big inspiration of course : )

[rigid island]

are you using a*?

[latent latch]

Use visual studio debugger and step through your code, otherwise you need more logging

[eager fulcrum]

yup

[latent latch]

oh yeah, may not be a state machine problem then

there's visual tools to see how they are pathing which you should probably be using

[eager fulcrum]

ye, I will probably code path drawing tomorrow to see what it "thinks"

[latent latch]

it already includes path debugging tools

I think it's enabled on the agent itself? Or probably in the gizmos menu

[eager fulcrum]

I’m using my own A*

[latent latch]

oh right ;p

[rigid island]

yeah then def drawing some visual debugs will help greatly

[lyric veldt]

guys i really need help

my code just breaks whenever I update anything in the code, even a comment

and it fixes itself if i update a script even a comment

I have 0 clue why this is happenign

[weak venture]

hey im starting up a new project and ive found myself wanting to just use events for almost everything. Whereas before I might be holding references to other objects now im just pinging events back and forth. But I'm wondering if I continue on with this at a larger scale, will i face performance problems? Or is this perfectly fine

[rigid island]

show code

[lyric veldt]

okok

[rigid island]

what does "just breaks" mean in this context

[lyric veldt]

im uploading a video right now to

demonstrate

[rigid island]

ok

[lyric veldt]

and the error line the code is pointing to makes 0 sense

https://streamable.com/fytvu7

so heres the video

[rigid island]

This is fine and usually preferred, lookup "Observer Pattern"

you still usually a refrence but its a 1 way street instead of 2 way

Eg your Subscribers will always need the Invoker reference but invoker doesnt care about subscribers or have to run their methods manually (called from that invoker script), thats the main benefit

[weak venture]

in the case of things that are effectively singletons im just subscribing to static events so i dont even need 1 way references

[rigid island]

show both scripts

PlayerShoot and Gun

[lyric veldt]

also the error isnt consistant either sometimes I get htis error sometimes I don't I have absolute 0 clue why

[lyric veldt]

ok

[rigid island]

like send links of scripts, dont make a video of code lol

[rigid island]

yeah I mean you could say thats still a reference but yeah, there should be no problems. With Static especially though make sure you are unsubscribing in OnDestroy

[lyric veldt]

https://paste.mod.gg/xegxjqaieioj/0 this is the gun.cs one
https://paste.mod.gg/hebtqwobdsmj/0 this is the palyershoot one

i'm also using a scriptable object for my guns

https://paste.mod.gg/xjokckmabjfn/0

[weak venture]

i think the error youre getting is real that the gunData is null and its just inconsistent the compiling/recompiling thing is maybe just a red herring but i dont know enough about scriptable objects to say what the cause might be

[lyric veldt]

https://paste.mod.gg/vxzxmqheqdpq/0 heres the error message

[lyric veldt]

i mean

all the stuff for the thingy

r filled

field

[weak venture]

like i bet if you add a check for gunData is null, it will come back true in the error case

[lyric veldt]

i will try that

[rigid island]

<@&502884371011731486>

[lyric veldt]

damn thats one expensive site service

[rigid island]

dudes using an AI generated PFP probably a mass spam account

[lyric veldt]

lol

[weak venture]

is there anything that deletes the scriptable object on cleanup or something like that?

[rigid island]

are you destroying it?

[lyric veldt]

i dont think so

[rigid island]

this.gameObject seems to be throwing I think

[lyric veldt]

hmm let me try that

[lyric veldt]

also i tried

nothing

[lyric veldt]

also I just tried

i think it was the reason?

i have 0 clue tbh

[weak venture]

oh yeah my b i just swa gun and the gundata first check but its gun yeah

[lyric veldt]

because the

error is so random

lol

[rigid island]

is gun gameobject disabled or anything ?

[lyric veldt]

nope?

i dont even know how to do that 💀 🙏

[weak venture]

i think you need to unsubscribe

right? youre sending an event to a dead gun maybe?

its that same issue you just warned me about

[rigid island]

but they said it never gets destroyed no?

[lyric veldt]

yeah

wait let me just check again

why would i even want to destroy the gun tho

ykwim

[weak venture]

but if you have that static reinitalize setting off isnt it possible its got a dead gun subscricption hanging around

the events are static

[lyric veldt]

the only time I ever destroyed an object

[rigid island]

idk maybe you have it on a weapon that destroyes? idk ur game

[lyric veldt]

is in my target script

[weak venture]

thats why its between game runs

[rigid island]

there is no Gun script on this gameobject?

[lyric veldt]

nope

is just a sphere

with a target script

[weak venture]

you need
OnDestroy()
playershoot.shootInpiut -= shoot
playershoot.reloadinput -= starterload

in gun

[lyric veldt]

let me se

[rigid island]

its good practice but dont think thats the issue rn

[lyric veldt]

yeah idk

[rigid island]

could be lingering event but doubt it

[lyric veldt]

i'm not even sure how i'm recreating the bug rn

let me just try to

[weak venture]

idk this same thing happened to me when i turned off that static reinitialize setting

[lyric veldt]

recreate the bug again

[weak venture]

idk if you have it on or not

[rigid island]

UnityEngine.Component.get_gameObject makes me assume is somehow this.gameobject

[lyric veldt]

how do i do that

[rigid island]

cause this runs a Get to the component GameObject its on

[weak venture]

but if you dont have that reinitialize setting on the static object still has a subscription to a now dead gun right

i dont remember the name of the setting let me poke around

[lyric veldt]

alright

[rigid island]

did you remove that line

and it still appeared on 25?

[lyric veldt]

ye

[rigid island]

and you saved right?

[lyric veldt]

is just this now

[lyric veldt]

eah

wait i got the error again

[weak venture]

run 1 - add subscription to gun, stored on static event in player shoot
end run 1 - gun is now dead, but subscription is never removewd
run 2 - if statics arent reinitalized, that static event still has a subscription to a now dead gun. You try to access the game object of the dead gun, but it is null

[lyric veldt]

😭

ok progress i think

wait

im

[rigid island]

maybe you have two scripts

[weak venture]

did you try unsubscribing on destroy?

https://discussions.unity.com/t/after-restart-game-static-variables-are-not-resetting/884957

your restart alone doesnt clear the subscription to the static eventt

so the event gets sent to a dead gun from the previous time you ran the game

[rigid island]

oh those are static..

then you Def want to unsubscribe..

[lyric veldt]

i just realized that im really stupid

and cant code

[rigid island]

for some reason the PlayerShoot just loaded in

[lyric veldt]

how would i be able to do that

sorry im kind of enw to unity

[rigid island]

the opposite of subscribing

if sub is +=

the opposite is -=

[weak venture]

add

OnDestroy()
{
playershoot.shootInpiut -= shoot
playershoot.reloadinput -= startreload
}

to gun

[rigid island]

every time you stop the game the static is still lurking in memory

[weak venture]

im guess it gets cleared/reset when you hit the error, which is why its hitting like every other time

[lyric veldt]

like this?

[weak venture]

yes

[lyric veldt]

let me try

[rigid island]

wish had seen that PlayerShoot script earlier lol

that site works very slow on mobile for some reason

[lyric veldt]

i think it works now

i have 0 clue how that bug even

like worked

so im keep messing around

tysm ygs

[rigid island]

unfortunate side effect of statics

and events

[weak venture]

any time you += to a static event you want that corresponding -= in OnDestroy

or maybe OnEnable/OnDisable yknow whatever is relevant to the context

[lyric veldt]

ah i get it

[rigid island]

normally I do
OnEnabled =>Sub
OnDisable => UnSub

[lyric veldt]

i have a question tho, is why does the bug isnt consistant

[rigid island]

this way no funny business if its disabled but stil in game

[lyric veldt]

i cant

type

like the bug isn't consistnt like sometimes it works sometimes it doesnt

[lyric veldt]

oh i just

read this

nvm

u guys r so smart 💀

[lyric veldt]

ahhhhhhhhhhhhhhhhhhh

[lyric veldt]

so basiclly the thingy didnt wokr becuase there were 2 instantce of the gun object, and it doesnt get destroyed the frist time it do funny stuff

sum like that

right?

[weak venture]

yeah the gun object from the first time you ran the game gets detroyed when you stop playing the game. But player input still is sending messages to that now destroyed object cause you never deleted the subscription. So when player input sends an event to a destroyed object and the code tries to run, it fails cause that object doesnt exist anymore and everything in there is null

[lyric veldt]

ah ok, tysm brtw

btw

[weak venture]

so the fix is like this

[lyric veldt]

okok

[lyric veldt]

tysm for u time

[weak venture]

np, gluck with stuff

[lyric veldt]

ty, you too

[night harness]

before anyone questions how weird this might look, in theory defining an explicit type like this should be serialization safe for Unity right?

public abstract class TaskBehaviour<T,U,V> : MonoBehaviour where T : ScriptableTask
{
    [field: SerializeField] public T Task { get; private set; }
    [field: SerializeField] public U PrimaryContext { get; private set; }
    [field: SerializeField] public V SecondaryContext { get; private set; }
    [SerializeField] private List<AINode> TaskNodes = new List<AINode>();
}

public class PurchaseTaskBehaviour : TaskBehaviour<TakeItemTask, ScriptableItem, int>
{

}

(assuming the types i'm using are chill for serialization ofc)

[half tundra]

Lads, quick question! Is it better for performance in a 2d game to have only 1 scene or to have many scenes, or is it better to be somwhere in between?

[mellow sigil]

The number of scenes has no effect on performance

[thin aurora]

Technically everything you add adds to performance, and this includes the scenes. However, please do not limit your scene count purely to save on performance, because it's very unlikely this has any direct noticeable difference and you just end up making things more complicated for yourself.

[vestal arch]

don't worry about performance unless a) it becomes a problem or b) you're doing very heavy work (1000000 ops per frame?)

[half tundra]

🫡 cheers

[wheat spruce]

I recently heard the perfect phrase "negligible at a human time scale"

[steady bobcat]

Premature optimisation moment

[wheat spruce]

I've never been able to phrase "yes that operation is slower than something else but it's not really possible to notice" in such a concise way

"negligible at a human time scale" works

[steady bobcat]

well for us it often if its noticeable at a frame scale but I think still applies

[vestal arch]

but oftentimes these things aren't frame scale

frames are in ms, the differences here may be in us or ns

[steady bobcat]

what i meant was in some programming settings something taking more than say 0.032 ms isnt going to be noticed by the user, but in a game it may be if it happens frequently enough.

[autumn crag]

Anyone know how to grab all the sprites from this sprite sheet and put it in a list without dragging in each one manually?

[rocky heron]

how should i handle checking if the player can jump? if i raycast in the middle, then if the player is on an edge he cant jump, but im not sure how else i should accurately check

[soft shard]

Raycasts work fine, a common approach is using a different shape like a sphere instead of a ray to do the casting, which can catch more of those (literal) edge cases: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Physics.SphereCast.html - there is also CircleCast for 2D, along with a few other shapes

[rocky heron]

can i visualize this to debug? i tried implementing it but it doesnt seem to work

bool hitSth = Physics.SphereCast(transform.position + new Vector3(0, .01f, 0), jumpCheckRadius, Vector3.down, out hit, MaxDistance + .01f, LayerMask.GetMask("Ground"));```
i put `jumpCheckRadius` and `MaxDistance` really high, still it doesnt become true.

last time i did it with debug,drawline but there doesnt seem to be a
debug.drawsphere

[soft shard]

For the other shapes of casting, you may have to use gizmos: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Gizmos.DrawSphere.html - otherwise theres a nice package I like using made by a community member: https://github.com/vertxxyz/Vertx.Debugging

[somber nacelle]

if you are on unity 2022+ you can use the physics debugger to visualize your physics queries. i also recommend the same debugging package dibbie just recommended

[rocky heron]

that looks crazy good thanks

[languid hound]

Physics debugger seems like such a hidden gem I don't see it getting talked about enough

[somber nacelle]

yeah it's pretty handy, finally being able to visualize physics queries is nice. too bad it's only useful for 3d though

[languid hound]

Oh crap that sucks I've never really done 2D games. Seems like a big oversight

[rocky heron]

do they do different things? or is the package just a better version?

[somber nacelle]

they work differently, and the package can be used for more than just drawing physics queries. it also supports 2d

i personally prefer the package over the physics debugger, but the physics debugger is already included and you don't have to make any changes to get it working so it's nice for quick tests

[rocky heron]

package doesnt seem to work :(

[somber nacelle]

that is an error from a completely unrelated package

and likely means you need to update it or just nuke the package cache so it is rebuilt

[rocky heron]

it only appeared once i installed that physics one though?

i didnt add the one from the error

oh it seems to be a dependency

[somber nacelle]

It was probably installed with the netcode package. Vertx's package doesn't use that

[rocky heron]

oh yeah weird that it only started acting up now

ive had netcode for a while

they both use burst

[somber nacelle]

just a random package cache issue probably 🤷‍♂️

[rocky heron]

alr ill delete the cache

deleting the cache folder in appdata did not fix it

or is it a different folder?

[somber nacelle]

the one in the Library folder within your project. the one in AppData is just the download cache

[rocky heron]

do i nuke the whole folder or only that one package

[somber nacelle]

whole folder usually. it will reimport all of the packages

just do it while unity is closed

[pearl burrow]

Hi guys. I've implemented a skill system. Now each time i update a skill i need to update the corresponding gameobject and im doing so through an even bus.

Every time i upgrade a skill i raise the event and every subscribed objects check if their skill id match with the raised skill id event. Is this a good approach considered that the event is fired to all the objects that are related to the skills?

[rocky heron]

uh... im gonna need a fix for this one as well now

[somber nacelle]

you only deleted the PackageCache folder which is located within the Library folder, not the Package folder from directly in your project, right?

[rocky heron]

i deleted all of these

[somber nacelle]

and you did that while unity was closed, right?

[rocky heron]

yes

when i opened it i had to wait for them to reinstall as well

i checked package manager and they are in there

[somber nacelle]

including the netcode and UI packages?

[rocky heron]

i pressed ctrl a and delete

cuz u said whole folder

[somber nacelle]

okay that does not answer whether those packages i asked about are in the package manager

[rocky heron]

oh i thought u ment delete

lemme check

alright i just re-restarted and now only the original 3 errors are there

[somber nacelle]

you ensured that all of your packages are up to date, right?

[rocky heron]

yes

[somber nacelle]

are you on an older version of the editor? because it does look like your netcode and unity transport versions are kind of old and that experimental version of collections is kind of old too, 2.1 released forever ago but should require 2022+ afaik

[rocky heron]

2022.3

[somber nacelle]

then you have some wildly outdated packages then and i don't understand why they aren't showing updates available

[rocky heron]

thats weird, i made this project this week

so its not like i downlaoded em years ago

im on 2022.3.22f1

[somber nacelle]

well you're also on a year old patch, but those packages still have newer versions for that patch

[rocky heron]

just removed the debugging package and its working again, ig i just wont use it

[rocky heron]

is that like a big issue?

[somber nacelle]

have any of the other package versions changed when you removed that?

[rocky heron]

collections went to 1.2.4

non-experimental

math went to 1.2.6

[somber nacelle]

yeah so that would be the issue then. since all of your other packages are wildly out of date, even for the version of the editor you are using, when that package was updated to the version that was required other packages broke.

i would recommend updating your editor to the latest patch then update your packages so things like this don't happen again

[rocky heron]

does that break anything in my project?

[somber nacelle]

updating to a newer patch would not introduce breaking changes, they typically only include bug fixes. but even still you are surely using some sort of version control and can revert any changes that break things

[rocky heron]

surely never knew/thought about version control
