Hello! I have firebase authentication, should this reward system be connected on firebase? or can I do this tutorial on its own? like when the users login, will they be able to use this reward system?

[crude elm]

Is this possible to set and add a Full Screen Pass Renderer Feature to the Universal Render data with code instead of an Editor menu?

[royal temple]

Hello guys, I'm using a Ray from my Camera and the Ray seems off by a fixed offset to the right, any pointer as to what could be wrong please ?

Here's the code (simplified):

var hits = new RaycastHit[100];
var ray = GameManager.Instance.MainCamera.ItemInvestigationCamera.ScreenPointToRay(Input.mousePosition);
const float castDistance = 100;
int hitCount = Physics.RaycastNonAlloc(ray, hits, castDistance);
float closestDistance = float.MaxValue; // TODO: Make this distance the current Room's AABB's diagonal
Interactable closestInteractable = null;
            
#if UNITY_EDITOR
UnityEngine.Debug.DrawRay(ray.origin, ray.direction * castDistance, Color.red, 2.0f);
#endif

And yes, the Camera being used is the one Camera which renders the Item I'm trying to click using that Ray, so it's coherent

[leaden ice]

nothing looks wrong with the code itself as long as the camera is correct

what makes you think it's off?

(side note - the way you are using RaycastNonAlloc with a new array each time is not ideal but that's an optimization issue for later)

[royal temple]

I draw it, and there is a clear offset to the right. If I click, let's say, about 70% to the right of my screen (middle vertically), the ray that I draw will be outside of camera frustum

[leaden ice]

I wouldn't expect this ray to be visible on screen at all

given that it's coming from the camera

[royal temple]

I'm looking at it in Editor

No in game view

[leaden ice]

in scene view?

[royal temple]

Yes, scene view*

[leaden ice]

Ok can you show a screenshot?

[royal temple]

You'd be right in saying it's invisible from Game View

I can't post screenshot as the game I'm working on is under strict NDA 😦 but I have looked at every angle and it's offset

[leaden ice]

My guess is you have tool handle pivot set to Center instead of Pivot perhaps

so you're mistaken about the camera's actual position

[royal temple]

What do you mean by "Tool handle pivot" ?

[leaden ice]

the one on the left here

[royal temple]

Because it doesn't seem to be a Scene View specific problem. The actual behavior doesn't work either (as in, my object doesn't get clicked)

It's under the mouse when I click and it doesn't react to the click, it's not in the list of Hits when I break into the code, and the visual debug shows me it's off, so this all seems very coherent

(but bugged)

[leaden ice]

what kind of object is it?

What kiond of colldier does it have?

etc

[royal temple]

A simple BoxCollider

It's just a gameobject with a BoxCollider and a component script to help me detect the right kind of object

Admittedly not the most optimized choice either but works well enough

[leaden ice]

From what you've shown me here so far I would expect it to work fine

[royal temple]

All right, I'll keep digging. thank you for trying

[ivory pasture]

do collider2d s inside canvas interact with those outside?

[hidden flicker]

Why doesn't the player move along with moving objects that it's on top of

It's a purely physics based player

Non-kinematic

[rigid island]

is this a guessing game?

[spring creek]

You are handling the movement directly using velocity and overriding forces?

You have no physics material on either?

Could be something else too

[polar marten]

use the kinematic character controller asset, which is free, to achieve this

[polar marten]

MainCamera.ItemInvestigationCamera.ScreenPointToRay(Input.mousePosition);

what do you expect this to do exactly? what camera is rendering? what is a main camera's item investigation camera?

you're using a ray from a camera, but i don't know what "my" camera means

also, this isn't the code, it's simplified, so there could be a lot of problems

[polar marten]

i suppose you can look at how the editor code does it, it's open source

[crude elm]

I did. There is a FullScreenPassRendererFeature class, but List<ScriptableRendererFeature> in ScriptableRenderer is internal. Also the data itself stored as an .asset file, so I'm not sure if changed would be applied to it permanently. I assume I need to somehow reuse ScriptableRendererDataEditor.AddComponent method that is also internal.

[swift falcon]

How the project settings works? I want to create my own settings. For instance, the physics tab. You can access the Physics Settings by Physics class which is not a static class. Then where it is getting the settings from? I currently saving my settings to the ProjectSettings Folder as a JSON file maybe that is the way?
I see there is no PhysicsSettings.asset inside ProjectSettings folder

[rigid island]

https://docs.unity3d.com/ScriptReference/PlayerSettings.html

[swift falcon]

Hm? PlayerSettings?

[rigid island]

myb i misread it from Physics to Player lol

[knotty sun]

The settings .asset files are basically just serialized ScriptableObjects

[swift falcon]

I got confused when i saw there is no PhysicsSettings file. I wonder where it gets saved. I have Physics2DSettings.asset even the game itself 3D but not PhysicsSettings.asset

Also how it loads? I guess its should be done by an instance? But there is no instance at their script wo... ._.

[arctic lintel]

my musicNSounds value is correctly set but my dropdown values aren't... even if I put a fixed value like 95, the value in the dropdown isn't changed. here's my bad code (optimization is for later rn I need a working code) and here's how I call it...all variables are correctly assigned

and if I put in update, the value is correctly set but I only needs at start... and I tried with a bool alreadyLoaded in the update and it wasn't working

[leaden ice]

Based on this explanation it sounds like you have some other code that's setting the Dropdown values after this code runs

You should also probably be using SetValueWithoutNotify

[arctic lintel]

I checked but no, nothing else is touching my dropdowns

[polar marten]

what's your goal?

like why do you need to add this programmatically? is the goal to do something at runtime? or as an editor feature?

[leaden ice]

How did you check

[polar marten]

if it's for editor scripting, use reflection

[arctic lintel]

searching for any ".value =" in my code bc I didn't used the SetValueWithoutNotify func

I changed every ".value =" to the func you gave me but still nothing 🥲

[leaden ice]

Where is LoadFromJson called?

Maybe multiple places

[arctic lintel]

in the Start()

[leaden ice]

Of what

[arctic lintel]

of my same script attached to an empty

[leaden ice]

Add more logs

Before and after this code for example

Make sure the values being read from the file are correct for example

It's also possible your UI element references are incorrect

[arctic lintel]

yeah they are I already tried

[leaden ice]

Lots more debugging and checking assumptions to do

[arctic lintel]

they are not, an other system uses the same variables

and still works

[crude elm]

I want to have an ability to insert FullScreenPassRendererFeature with a predefined name and a material for Fade Out effect. I don't like to fiddle with Unity settings and try to have setup for everything in one static class with MenuItem methods. But maybe adding the feature for the active renderer data in a bootstrap scene will make more sense.

[hidden flicker]

Yeah, I'm currently using direct transform modification with MoveTowards... I want to make a floating platform which moves the player with it, and doesn't fall or "feel" the weight of the player at all.

Basically something which is only affected by its own interal forces, and not external forces

[swift falcon]

It seems they called the PhysicsSettings.asset as DynamicsManager.asset. But anybody can help me how this Serialized ScriptableObject gets handled?
I want to create my own settings that can be accessible like Physics class. Lets say the settings i create is named as "CustomAppSettings". How would the CustomAppSettings.asset in ProjectSettings gets loaded?
I am thinking to use an instance right now.

[spring creek]

Ok, well you're gonna have to manually move it along with the platform them. If you use transform directly, it will not respond to any forces like friction

You can try parenting to the plaform

Or adding the platforms movement to the players while some spatial query tells you the player is on it (same thing as grounding, but you search a tag or script that tells you it is a platform)

[polar marten]

there are a lot of ways to achieve a screen fade out without messing with full screen render passes

for example, a canvas image

another one is a volume

[prime quarry]

Asriela — Today at 20:39
I was making an alarm struct to give me easy to use timer functionality in unity, but i get an error saying i cannot modify a collection im assuming in a foreach but I cant figure out how to do a for with a dictionary

[fervent furnace]

ok
the foreach loop is actually some codes like:

while(collection.HaveNext()){
  var c=collection.Current;
}

and you are modifing the c, a value type and a copy of the value in collection

[somber tapir]

In Visual Studio you can use quick suggestions to convert a foreach to a for loop

[fervent furnace]

oh i misread, you are modifing the collection directly

it is prohibited in foreach since it causes iterator fails

[prime quarry]

i didnt get that suggestion, even when i click the lightbulb now, strange

[somber tapir]

I suggest not using Dictionairies though. Make that a class of it's own.

[prime quarry]

why is that

[fervent furnace]

you cant use for loop to iterate dictionary (though you can use reflection to get the entries array)

[leaden ice]

quick hack:

var keys = alarms.Keys.ToArray();
foreach (var key in keys) {
  // the rest of your code
}```

I would probably set this up so it's a dicitonary of alarms to the "end time" for the alarm, rather than constantly modfiying them though

then you don't have to worry about modifications at all

[simple egret]

Side notes to fix for later: follow naming conventions, method names must be in PacalCase: run() -> Run()
Types must also be PascalCase: enums - do not name this "enums", give an explicit name so you know what it contains at a glance

[prime quarry]

end time? Im not following

[leaden ice]

the time at which the alrm goes off

instead of decrementing all the timers in a loop

you increment ONE external timer variable

and check if the time in the dictionary is <= it

[prime quarry]

oh I am only doing enums because its my general scrappy enums within my shortcuts class Az for asriela i have other sets of enums like Objects in Az class too enums is just the loose bits enums

[simple egret]

Oh god

[crude elm]

Yes, but isn't Fullscreen Shader suppose to cover this as well? From what I've read it allows to fade out, make transition and apply effect over the camera. And in URP it requires to add a feature per shaders or swap materials. However, I wasn't aware that Volume can black out a screen.

[simple egret]

Cramming the ones you couldn't categorize in a single enum, bad idea lol

enum AlarmType - Even if it contains just 2 values it's still worth it to make a separate one

[somber tapir]

It makes things cleaner and more extendable. What if you want to add something to your alarm, like listeners. You'd have to add a new Dict for every new variable and they are not linked with each other. Or if you want to have different types of alarms, maybe one that triggers multiple times, you'd have to use multiple if statements.

[polar marten]

i don't know why you are wasting your time with these features and editor scripting when it will take you 15s to build a canvas

with a black rectangle in it

all the alternatives are worse

why author a shader? what is the purpose of all this nonsense

@crude elm i suppose you're not sure why you got into that rabbit hole but it's okay. make a canvas. what you are asking to do otherwise is not supported.

[prime quarry]

yeah going through my scraps enums I have actually moved away from all of them and can just make an alarms one yeah

[prime quarry]

sooo an array of structs or an array of objects from a class?

how would i set up key value pairs with objects

[strange gate]

Hello can someone explain how to fix this error?

[prime quarry]

i am realizing how convenient game makers Map datastructure was, but obviously limmited if you wanted to do advanced stuff

[spring creek]

Do you have a class called ProjectileGun?
And called that EXACTLY (same capitalization?)

If you do, is it in a namespace?

[crude elm]

Because canvas isn't work well with XR and I'm not sure how to apply effects to canvas. With a fullscreen shader I can use noise, gradients and whatever.

[leaden ice]

you're using a class that doesn't exist

[prime quarry]

as in you count up and then check if an totalTime/individualTimerLength = round number? sorry i feel like im missing something

[strange gate]

how to create one because I dont really know what is a class in unity 😄 but.. yeah

[leaden ice]

for example:

timers:
1 -> 5
2 -> 10

current time: 0

each frame you increase current time by deltaTime
You check each timer in the dictionary. If current time is > that time, that timer is done

so when the timer gets to e.g. 5.032, timer #1 is done

it would just be a if (currentTime >= timer[key]) check

[spring creek]

public class ProjectileGun

You may want to take the !learn courses

[tawny elk]

:teacher: Unity Learn ↗

[leaden ice]

a class? Every time you write public class something you created a class.
It has nothing to do with Unity, it's a C# thing, though Unity "scripts" are often 1:1 with classes

[somber tapir]

you might know it as 'script'

[prime quarry]

ok but what if you then reset that timer and now the total time is 7, getting close to ending that second timer but now it instantly ends the first timer again ?

[simple egret]

No, because you popped the first one from the dictionary

It's essential to do that, once a timer is done, remove it from the collection

[leaden ice]

reset what timer?
If you reset a timer you'd put a new number in that's 5 seconds away from now if you want to "reset" it

so e.g. that alarm would be at 12 seconds if it's currently 7 seconds and you want it to last 5 seconds

you can call them "alarms" really if you want to be more accurate with this paradigm

[strange gate]

Oh my bad

[polar marten]

i see... i think there are going to be a lot of surprises in your project and maybe don't go with the editor script solution and just set it up manually

[prime quarry]

the whole point is to be able to go: alarm.Start(Az.Timer.spawnInterval, spawnInterval, true); and now I have a looping timer - with the true argument saying it loops. (Adding looping now)

[polar marten]

i apologize because it is going to be hard to achieve anything in XR

[prime quarry]

so i can refer to specific alarms/timers and have them be created, started and set to looping or not all at once

[crude elm]

Alright, I'll try Global Volume first. 👀 💦

[simple egret]

Since one timer can have more than one property (time + is it a looping one?), I'd switch to a class or struct, and have a list of that. It's better so you have it all easily accessible in one place

Then for looping ones, once it reaches the set time, just add currentTime + interval to the timer and you're good to go

[prime quarry]

yeah im seeing how dictionaries are annoying now ok so if i switch from dictionary to struct if i use a list or array to contain the structs then enums wont work so well because if i add enum with value 5 then i now have a list of size 5 instead of a single keyed entry of value 5

[prime quarry]

oh yeah,sweet thanks

[simple egret]

The struct could contain a property of your enum type, so each one has its own alarm type

public AlarmType Type { get; } or something

[prime quarry]

so how would I find the struct with the correct enum type assuming im storing them in a list

oh id just have to iterate through them all

manually

[simple egret]

Why would you need to find a specific one yes?

Since you need to update them all at once, you can loop through the list unconditionally

[prime quarry]

so i can reference one

for example, if (alarm.Ended(performanceTimer)) {do performance heavy code}

[simple egret]

Riddle me this, what if there are 4 alarms of type performanceTimer that are finished when you call this function? What does it do?

[prime quarry]

well either I dont add multiple performance timers, unless i accidentally do that and even then i can just throw an exception if i try creating a new timer with an existing id (to ensure unique keys) but even if i dont do all that it will just find the first entry with that key and check its value

[swift falcon]

can anyone tell me how i can check if a function could be called in unity or if it throws an error. in c++ you just do if( function() ) but idk about c#

[simple egret]

So if you can have only one of the same type, then you can keep that Dictionary<TimerType, Timer> (whatever you're going to call the class/struct that holds the timer info), and do not add the TimerType inside the Timer type

[strange gate]

So I need to rename my class into my actual game gun?

[simple egret]

Do not post the same question in multiple channels at once please

[somber tapir]

You can always call a function. Do you mean to check if it would have an error in the method itself? Or maybe you are talking about delegate reference, you could check them with a null check.

[simple egret]

No I think you need to !learn C# as you told us you don't know what a class is

[tawny elk]

:teacher: Unity Learn ↗

[swift falcon]

ok

[tardy moss]

Is it legal for this discord if in unity learn I skip the basic c# specific stuff because Ive been using it for a couple of years I just need to learn the unity specific c# stuff ??

Like I know you could check my badges/progress if you wanted

[spring creek]

Is it legal?
You can do anything you want. It is elective

[simple egret]

Straight to jail

[clear rampart]

I have a problem. So basically i'm doing a clicker game and I have an upgrades class for every upgrade. The thing is I created a function for buying those upgrades that basically what it does is updating the values inside the class but I don't know how to make a generalized name for that class. For example
public void BuyUpgrade(UpgradesData upg)
{
upg.quantity += 1;

    Debug.Log("Purchase Done Successfully.");
}

so I don't know how to call that function and give it the name of an existing class.

I hope you undersatnd the problem

if I don't find a solution I will have to create a function to buy every upgrade.
That's what I'm trying to optimise

[tardy moss]

Ive been here a few days and I see you guys telling peoples to use unity learn before they asks question and the bot says there is 750 hours of learning. So I dont know if Im expected to pass all of it or something

[spring creek]

We tell people that when they expect us to teach them

It is a free course they can take on their own time.
When they have specific issues that show they understand the basics, that is a better use case for this discord

Do what you want from it. But if someone points you to it, it means that you are missing something crucial that the course explains.

Like what a class is

There are many other courses online too, you can use any you would like

[somber tapir]

I think what you are looking for is C# polymorphism and inheritance, google that.

[prime quarry]

So I have run into an issue in that structs cant be nullable

[simple egret]

Yeah. I have a hard time understanding the question though, is it about naming things? Or inheritance? Or both? Other????

[lucid valley]

structs can be nullable

[quartz folio]

If you place a ? after the type SingleAlarm? then they can be nullable.

Generally better to use the TryGet pattern though

[strange gate]

Nice i'm going to do 38houres course 🙂

Im down

[prime quarry]

when i do that the type field becomes inaccessible

[quartz folio]

I don't know what that means

[quartz folio]

How do you know if alarm has a type if it's nullable?

You need to check alarm.HasValue and use alarm.Value

[prime quarry]

as in if(alarm.HasValue && alarm.type== typeLookingfor)

[simple egret]

The list shouldn't contain nullables

Only the local variable that might store (or not) the alarm it found

But I'd use the TryGet pattern, it's better for that very specific case

[tardy moss]

wut ? unity still don't have alarm?.value ?!

[quartz folio]

I don't think C# works like that with nullable structs in any version afaik

[prime quarry]

dont get me wrong i left game maker studio for a reason but it does have many handy functions ive been recreating in unity

[tardy moss]

shrug I guess Ill never understand why int ?somevar; somevar?.ToString() is fine but not somevar?.Value and have to check .hasvalue every time

[simple egret]

what?

Like v?.ToString()? Well the compiler expands if to an if statement that does if (v.HasValue) v.Value.ToString()

So it works

[tardy moss]

No Im just pissed of that I have to check .hasvalue and != null every single time for a nullable

[simple egret]

No you don't have to

[tardy moss]

instead of just doing ?.Value just seems random things microsoft did to be annoying

[simple egret]

x?.Value is nonsensical since ?. already checks if there's a value for nullables, so ?. accesses the underlying type

[somber nacelle]

not only that, but the context of the issue is within an if statement. an expression using the null conditional operator (?.) evaluates to null if the object the operator is used on is null and you cannot just do if(null)

[tardy moss]

This is what I mean btw. I do know it's just it annoy me every single time especially that the struct is a value type and so is int:

[simple egret]

Because what's after ?. is a value of type SingleAlarm

You would be able to get the getupyou.... member if it was public, here

[prime quarry]

Im gonna try understanding the try get pattern tommorow from what i read up online its still confusinf to me

[somber nacelle]

btw you do know the GetValueOrDefault method exists, right? you can use that if you just want either the value of the nullable struct or the default value of the struct

[tardy moss]

ok lol it was just a mistake then 😄 I really thought for the last 10 minutes that MS had randomly decided it didnt work for structs but I turns out I just forgot the public

[tardy moss]

Yeah I know but I have coded for a long time(ie: since .net 1.1) and sometimes I forget the new stuff out of habits and uses the full if != null and hasvalue ...

[prime quarry]

Comming from game maker studio to c# makes c# feel like an elderly person who constantly goes "HUH what did you sayy?? You got to speak up sonny and be specific!"

[leaden ice]

Basically it sounds like you're not used to dealing with statically typed languages

[rancid void]

whats my mistake?

[leaden ice]

They may seem more tedious, but static typing is a godsend

[leaden ice]

wdym by mistake? What's the issue you need help with?

[somber nacelle]

https://unity.huh.how/runtime-exceptions/nullreferenceexception

[rancid void]

. @leaden ice

[somber nacelle]

basically either you never assigned GameManager.instance or this object does not have a TextMeshProUGUI component

[leaden ice]

either GameManager.instance is null or textMesh is null

figure out which one

[somber nacelle]

in fact, i would be very surprised if it has a TMP_Text, a Button and an Image component

[rancid void]

but textmeash is only for text right and i need a button

im a beginner

[somber nacelle]

sure, but does this one gameobject have all three of those components on it? or are they perhaps children of the object this component is attached to?

[somber nacelle]

well there you go, it doesn't have a TextMeshProUGUI component

[leaden ice]

notice how the object CLEARLY has no text component

[tardy moss]

I like both. Javascript quickly allows me to poke a rest api because it doesnt care about types. Then once I figure it out I can make an app in c# to use it. I couldn't live without either

[rancid void]

i dont understand sorry

[leaden ice]

on the right side of your screen is the inspector for the object

It shows all of the components

there is no TextMeshProUGUI component there

your code is saying textMesh = GetComponent<TextMeshProUGUI>(); since no such component exists, it will simply return null

then when you try to use this null variable you get an error

Is that clear?

[rancid void]

yes

so i have to use image right?

because when i want add a textmesh it show this

[wise pumice]

https://gyazo.com/3c718898f56c34c6fcf85ea74db92e9e

Anyone have any idea why this is happening?

Trying to set up my character to move with the platform

[somber nacelle]

so get a reference to the TMP object

[leaden ice]

You've clearly never worked on code other people have written!

[rancid void]

i look it up on youtube

[prime quarry]

Oh so in large projects it allows for like a history so you can track code better

[leaden ice]

no it allows for knowing wtf the type of variables are so you know what you're working with.

[prime quarry]

Thats what i meant

[leaden ice]

and it tells you at compile time when you try to do something like accessing a method or variable that doesn't exist

[prime quarry]

In that u may know the history of what u have written but others dont

[leaden ice]

or try to pass an object of the wrong type into a method, etc.

We call this "type safety"

[prime quarry]

Then again not like i remember wtf i wrote myself for long lol

[tardy moss]

How would you add a Texture2D and the number 2 together when it code it says somevar= some texture2d + 2

[thick socket]

public class DamagePopup : MonoBehaviour
{
    private TextMeshPro textMesh;

    private void Awake()
    {
        textMesh = GetComponent<TextMeshPro>();
    }
    public void Setup(int damageAmount)
    {
        textMesh.SetText(damageAmount.ToString());
    }

    //create a damagePopup
    public static DamagePopup Create(Vector3 position, int damageAmount)
    {
        Transform damagePopupTransform = Instantiate(GameManager.instance.pfDamagePopup.transform, position, Quaternion.identity);
        DamagePopup damagePopup = damagePopupTransform.GetComponent<DamagePopup>();
        damagePopup.Setup(damageAmount);

        return damagePopup; 
    }
}

as a "static" noob

why would you use static here?

dont fully understand why static is ever used tbh

[somber nacelle]

it doesn't touch anything in the instance so it doesn't need to be an instance member

[thick socket]

I dont quite follow what that means

[simple egret]

And it's more of a "factory method", it's made to create, set up, and return the object for you

It's accessible everywhere from anything

[tardy moss]

static keyword imply that you wont touch an instance of damagepopup. Following OOP principles any operations related to DamagePopup need to be in a DamagePopup class. But some operations don't need an instance of the class

so static here semantically says, this feature belongs to me but I dont need to get some data from myself or change myself to do it

[leaden ice]

The only difference between a static method and a non-static one is that non-static methods include an implicit "this" reference, which is the object you called the method on. when you say someObject.SomeMethod() you can imagine that you're actually calling a static function with someObject as the first parameter to it, which can be referenced inside the method as this.

If you don't need the this reference at all in the function, there's no need to include it, thus you can make it static

[thick socket]

hmmm, so with a "static" in this case

I can just do DamagePopup.Create

instead having to create a new DamagePopup and then call "create" after it?

[lean sail]

just a small thing, i would skip the whole Transform step here, and directly instantiate it from its DamagePopup. saves you a get component call, because you arent using the transform anyways

[thick socket]

I can't seem to wrap my mind around how that would work?

[tardy moss]

I miss static variables inside method 😦

[thick socket]

Dont I need to the transform to "getcomponent" of the damagepopup?

[somber nacelle]

if you pass a DamagePopup type into Instantiate then it returns a reference to the instantiated DamagePopup component completely removing the need to use GetComponent

[thick socket]

DamagePopup damagePopup = Instantiate(GameManager.instance.pfDamagePopup, position, Quaternion.identity).GetComponent<DamagePopup>();
damagePopup.Setup(damageAmount);

return damagePopup;

just like this instad?

[lean sail]

it works the same way as you are doing with Transform already, just do it with DamagePopup instead

[somber nacelle]

remove the GetComponent call

[thick socket]

it throws a "can't convert type"

[somber nacelle]

yes because you went and added .transform to it again

[thick socket]

oh interesting

I see that now thanks

for some reason I thought it had to have a Transform to be "Instantiated"

I if I wanted to make my own class that just Debuged.log 2x everytime I called it I would do this right?

public class DebugLog: MonoBehaviour {
public static void create2x(string message)
    {
        Debug.Log(message);
        Debug.Log(message);
    }
}

could just call

DebugLog.create2x("test");```

[somber nacelle]

it doesn't need to be a MonoBehaviour for that, but yes

[thick socket]

dang

this would have saved me so much time for years thanks!

always thought it was super annoying having to create an object to then call functions on it 😄

[stable geyser]

Hey all, trying to create broadsides style naval combat in my 2D game. Tried to find a tutorial to show me how to do this but can't find anything. User should be able to choose to fire out port or starboard sides with different keys. They can hold the fire button to "charge" their shot which affects the spread of the projectiles fired. Anybody know where I might find a tutorial on something like this?

Oh and I also need a visual indicator for the player of the charging step 😛

[unkempt meadow]

OK so why does controller crouch work the way it does? It reduces the collider inward, making your legs fall through the floor. I struggle to see the use of that

[hard viper]

Most shader tutorials don't seem quite right for this. does anyone have advice over how to do this?

example: I have a water shader, and lava shader, and both tiles could be on the same tilemap (or whatever), and I know I have water at positions A,B,C and lava at D,E,F, and I want to apply the water shader for A,B,C and lava shader for D,E,F. How would I even start to set this up?

[arctic lintel]

settings.keybindSystem.p1.forward is a dropdown that the default value is 68, I'm trying to change the value but it doesn't work
here's everything you need to help me...
btw, my menu with my dropdowns is not Active to hide the menu when not suppose to be seen but even when the menu is Active, and the dropdowns are visible... the value doesn't change...can anyone help me with that?

[thick socket]

Any chance yall could help me figure out what VS shortcuts he does here from 15:00->15:10?
There are quite a few and seems to save a lot of time but I can't figure out how to look them up(or what they might be called)

https://youtu.be/iD1_JczQcFY?si=0sXQTMvaA2PTaRUZ&t=900

[simple egret]

15:05 - Shift + Enter to add a line above. Or Ctrl + Enter. I don't remember.
15:09 - Ctrl + R twice to rename the identifier under the cursor, and update everywhere it's used.

• This works across the whole project, so if you're renaming a variable that's public and used in 15 scripts, it'll do the rename in the 15 scripts.
• When renaming a class, it will also rename the file for you.

[kind cipher]

This is a scene I haven't had to touch for months, but today, string split is misbehaving. This is the logic where it splits the string.

foreach (FsmString pair in customSessionProperties)
{
    Debug.Log(pair);
    string[] keyValue = pair.Value.Split(',');
    string key = keyValue[0];
    Debug.Log(keyValue[1]);
    string value = keyValue[1];
    SessionProperty property = value;
    properties.Add(key, property);
}```

here is the console log

its skipping over the word arena

in 8 months its never done this. why now?

[simple egret]

What says it's skipping it, you're not logging key nor keyValue[0]

[hard viper]

I would use the debugger to look into what is in these variables

[kind cipher]

thanks yeah. jsut caught that myself. Still confused. Its getting my first pair in the dictionary, but my next pair its returning empty values.

[hard viper]

instead of using debug.Log

is there a simple way to make a shader that operates on a specific type of tile?

[simple egret]

#archived-shaders professionals will be able to answer you most likely

[thick socket]

    private static int sortingOrder;
 public void Setup(int damageAmount, bool isCriticalHit)
    {
        sortingOrder++;
        textMesh.sortingOrder = sortingOrder;
    }```

am I going to run into issues where the sortingOrder int is being accessed twice at the same time

and thus both will be ex)10 and then the 3rd will be 12

not sure how unity might thread things

[simple egret]

Unless you multithread yourself, no code will be executing twice at the same time

[thick socket]

awesome thanks

didn't know you could really multithread yourself with unity

but I guess maybe Async could do that

[spring creek]

Async is not multithreading, it's more like coroutines where it works ON the main thread, but yields it so other code can run

[polar marten]

it stands to reason customSessionProperties has a value that does not contain a comma

[thick socket]

good to know thanks

[hard tapir]

Multi thread is Dots right?

[spring creek]

Jobs can multithread

Dots is multiple things. Jobs, Entities, and the Burst Compiler

[hard tapir]

Yeah, but I would like to Object oriented programming to be multi threaded too

[spring creek]

Ok, jobs can be done with oop 🤷‍♂️
Or multithread another way

[simple egret]

For completeness C# does provide methods for handling access from multiple threads in an atomic manner, which means the use is locked to the thread that is modifying the variable, to ensure nothing else is accessing it in the process.
For example, there's Interlocked.Increment() which is used to atomically increment a value

[hard tapir]

That's nice! Time to optimise my game

[polar marten]

what are you asking? how to implement crouching in an fps using ordinary unity physics? character controller: change the shape. rigidbodies: save the velocity, toggle colliders for the different shapes, then restore the velocity.

[hard tapir]

How to make corners to be square ⬜ if segments count is 1. Currently it makes triangle. ```var u = 0f;
for (var c = 0; c < 4; c++)
{
// Create verts
var origin = _corners[c];
for (var i = 0; i < _cornerSegments + 1; i++)
{
// Calculate angle and direction
var angle = (float)i / _cornerSegments * Mathf.PI / 2f + Mathf.PI * 0.5f - Mathf.PI * c * 1.5f;
var direction = new Vector3(Mathf.Cos(-angle), Mathf.Sin(-angle), 0f);

    // Calculate vertex position for the inner corner
    vert.position = origin + direction * clampedCornerRadius;
    vert.uv0 = new Vector2(u, 0f);
    _verts.Add(vert);

    // Calculate vertex position for the outer corner (outline)
    vert.position = origin + direction * (clampedCornerRadius + _outlineWidth);
    vert.uv0 = new Vector2(u, 1f);
    _verts.Add(vert);

    // Fill center condition
    if (_fillCenter)
    {
        vert.position = rect.center;
        vert.uv0 = new Vector2(u, 0f);
        _verts.Add(vert);
    }

    // Increment u based on segment or edge length
    if (i < _cornerSegments)
        u += segmentLength / around;
    else
        u += edgeLengths[c] / around;
}

}

[polar marten]

is this a mix of your own and chatbot authored code?

[unkempt meadow]

Changing height of the char controller capsule collider reduces it inward, the center being the point of origin, instead of the base

[polar marten]

i think you can figure out how to adjust its shape correctly

there are dedicated, free fps character controller assets that may be more useful though

are you trying to change the height over a period of time, or instantaneously?

[unkempt meadow]

Being a unity built-in feature, I struggle to see why the base couldn't be the point of origin, it doesn't make any sense otherwise

I have all the movements and controllers

I just never got around to reducing the collider while crouching; only playing the animations

over a short period of time

[polar marten]

it is a lot harder to change the shape over time

you are overthinking this. in the editor, design the two collider shapes so that it looks right to you. then copy those settings

don't try to change the shape over time

[hard tapir]

Nope, it's from github.

[red bramble]

I've got a concept for making a lock-on system for my fixed-camera game that I'd like to run by somebody if they have the time.

I'm in the prototyping stage for it and I'm wondering if my thought process is going the correct way for this.

[thick socket]

not sure if #archived-code-general is the best place for that?

[leaden ice]

#archived-game-design probably or #1180170818983051344

[red bramble]

Unless I'm misunderstanding something, it is still a coding question no? Or is #archived-code-general for base Unity Coding, non-game related?

[thick socket]

¯_(ツ)_/¯

[leaden ice]

Well it sounds like you're worried about the concept/game mechanic from an abstract level, rather than some code issue. That's #archived-game-design stuff

[thick socket]

you didn't ask anything coding related

[hard tapir]

.... Anyone?

[red bramble]

I am considering how to implement it, which involves the coding portion of the implementation. I had an existing system with raycasts, however it doesn't fulfill the lock-on system portion of the requirement. I asked the basic question because I was seeing if anyone was even available and interested in helping.

Regardless, I suppose I'll switch to #archived-game-design

[rocky basalt]

Hi. I have a situation where I'd like to pass a base class into a method and then cast it as an inherited class. This would not be done every frame - maybe every few seconds or so.

I remember reading some Unity docs about "boxing" and casting creating memory issues, but I'm a programming n00b.

Wondering if anyone could sanity check whether I should be concerned about casting such as "MyBaseClass class = MyBaseClass as MyInheretedClass" <--- I know that syntax might be wrong, i just wrote it from memory

[simple egret]

No there's no problem at all with casting. In fact casting does not modify the memory at all, it just does checks to ensure what you're casting to is the expected type. So it's pretty much nothing to worry about in terms of performance.
Boxing happens when there is a cast from a value type (a struct, for example int) to a reference type (eg. object). This forces memory to be reserved to store the int as object

[rocky basalt]

Thanks for the response. Value to ref type is what creates the boxing, that's right!

Every time I read some performance warnings in a doc, I mentally file away as "here be dragons" without necessarily understanding the exact reasoning/machinations behind the warning lol.

[simple egret]

And it's mostly never a performance problem unless you're doing the thing thousands of times per second.
As always, if there are performance issues use the profiler to locate the source and fix it

[thick socket]

I can do a pool of type GameObject right?

running into issues with trying to check a dictionary and it doesn't seem to want to be the same key

[rocky basalt]

For sure. I do find it's been helpful to build good habits while building stuff, rather than building something with terrible habits and then having to re-learn everything with the profiler

[thick socket]

if I put a gameobject as a key

cloned it

would they both count as the same key?

[rocky basalt]

No, if you clone it, it has a different instanceID and all that. So it's a different key

[thick socket]

"rips out hair"

thanks

[rocky basalt]

Yeah it's easy to trip over value vs references when learning Dictionaries and such. If you use a reference type like GameObject as a key, it's checking for that particular instance

[thick socket]

RIP my pool 😦

public class BasicPooling : MonoBehaviour
{
    public Dictionary<GameObject, ObjectPool<GameObject>> BasicPool = new();
    [SerializeField] List<GameObject> items;
    public static BasicPooling instance;

[rocky basalt]

I read the code you deleted before, there was a lot going on and I think you can simplify it a lot. Did you follow this guide yet? https://learn.unity.com/tutorial/introduction-to-object-pooling#5ff8d015edbc2a002063971d

If you wanna feed the dictionary a key that represents a certain 'type' of object, there are other ways of doing it. For example, give every object type an integer that represents it. There are surely better ways too, I'm not an expert

[thick socket]

with any luck it will work like this now...

hurray 😄

[thick socket]

public class BasicPooling : MonoBehaviour
{
    public Dictionary<BasicPoolEnum, ObjectPool<GameObject>> BasicPool = new();
    [SerializeField] List<EnumObject> items;
    public static BasicPooling instance;


    // Start is called before the first frame update
    void Awake()
    {
        instance = this;
        foreach (var item in items)
        {
            var tmpPool = new ObjectPool<GameObject>(() => CreatePooledItem(item.gameObject), TakeFromPool, ReturnToPool);
            BasicPool.Add(item.basicPoolEnum, tmpPool);
        }
    }
    void TakeFromPool(GameObject item)
    {
        item.gameObject.SetActive(true);
    }
    void ReturnToPool(GameObject item)
    {
        //Do Particle Explosion
        item.gameObject.SetActive(false);
    }
    GameObject CreatePooledItem(GameObject tmpItem)
    {
        var item = Instantiate(tmpItem);
        item.transform.SetParent(transform);
        return item;
    }
    public void Release(BasicPoolEnum basicPoolEnum, GameObject item)
    {
        BasicPool[basicPoolEnum].Release(item);
        Debug.Log("released");
    }
}
public enum BasicPoolEnum
{
    damagePopup=0
}

[Serializable]
public class EnumObject 
{
    public BasicPoolEnum basicPoolEnum;
    public GameObject gameObject;
}

[thick socket]

basically just an enum yeah 🙂

[lean sail]

i do mine based on Component instead,
Dictionary<Component, ObjectPool<Component>>
so the pool can return a specific component i want rather than having to call GetComponent each time you want a pooled item. Although it requires a cast to the right type, it is better than GetComponent

[rocky basalt]

Dammit i still don't know how to make code look nice

[lean sail]

i wouldnt really do it based on ints unless this class also provides a lookup for object to int.

3 backticks and write cs after the first 3

[rocky basalt]

int objectOneID = 0;
int objectTwoID = 1;
List<int> myObjectIDs = new List<int>();

GameObject goToSpawn;
int amountToSpawn = 10;

public Dictionary<int, List<GameObject>> myPoolsDict = new Dictionary<int, List<GameObject>>();

private void Start()
{
    myObjectIDs.Add(objectOneID);
    myObjectIDs.Add(objectTwoID);

    PoolObjects(myObjectIDs);
}
void PoolObjects(List<int> listOfInts)
{
    foreach (int itemID in listOfInts)
    {
        List<GameObject> pooledObjects = new List<GameObject>();
        for (int i = 0; i < amountToSpawn; i++)
        {
            GameObject spawnedObj = Instantiate(goToSpawn);
            pooledObjects.Add(spawnedObj);
        }
        myPoolsDict.Add(itemID, pooledObjects);
    }
}

[thick socket]

but then you need a new pool per component

[lean sail]

🤔 honestly this doesnt make a lot of sense, theres 1 goToSpawn but 2 object ID's which seemingly arent used to reference different objects. This would also be a nightmare to use, everytime you want to add to the pool you have to edit the code or open this file to see what the ID was.
https://github.com/Unity-Technologies/com.unity.multiplayer.samples.coop/blob/v2.2.0/Assets/Scripts/Infrastructure/NetworkObjectPool.cs
This is a good implementation, it was made for network objects in unity netcode but very very easy to swap to component based like I wrote above.

[lean sail]

why would you?

[rocky basalt]

Yeah I neglected to add a second GameObject. I agree the weakness is having to add a new intID and knowing what is what, but there are ways to do it I'm sure.

Just wanted to share the outline/principle quickly

[polar marten]

what is the gameplay purpose of what you are doing

[leaden ice]

memory/performance issues are actually close to the least important factor you should be worrying about here. The bigger question is why is your code architecture set up in such as a way as to need such a thing?

[spring creek]

A single component reference can be used to get all components on the gameobject. It just speeds things when you know you'll mostly be using one of them when you grab it from the pool

[thick socket]

Oh cool thx, thought he just wrote "component" as a fill in for components

[thick socket]

Is there a way to "prewarm" with the built-in ObjectPool?

[rocky basalt]

Honestly I probably don't need to cast. I've been refactoring code the last few days and was going to use that 'thing' as a bit of a shortcut. But in simplied terms, Class C enables some 'modular' gameplay behavior where it can take in both ClassA or ClassB as building blocks. Just wanted to use one list instead of two. But, I could probably get rid of ClassB entirely since it kind represents clusters of ClassA. I'm aware none of that made sense

[lean sail]

yes, the linked i posted here does it on lines 137 to 145
#archived-code-general message

[shrewd mulch]

does any one know how to make a new spline in a sprite shape 2D

looks to me you'd probably use

never played with it

If you just want splines without all the baggage of SpriteShape you can use the Splines package

im not cross posting because this is a different question, this is how i draw the arcs which im showing in the image belowcs //Draw upper arc and lower arc Handles.DrawWireArc(scientist.visionPosition.position, scientist.visionPosition.up, upLeftEndpoint - scientist.visionPosition.position, scientist.xVisionAngle, scientist.visionRadius); Handles.DrawWireArc(scientist.visionPosition.position, -scientist.visionPosition.up, downRightEndpoint - scientist.visionPosition.position, scientist.xVisionAngle, scientist.visionRadius);

how can i tilt these arcs to be pointing in the same direction as the lines which i marked orange in the picture below?

Crazy question but I can't seem to find the list of supported items for UI Toolkit. Trying to make property drawers for custom playable clips but its not working even though everything else works. Anyone know where I can find the supported elements list?

https://docs.unity3d.com/2020.1/Documentation/Manual/UIElements.html

[rocky basalt]

you made me curious to know why this is a red flag

[tardy moss]

for me it is one one because it sounds like premature optimization

[rocky basalt]

probably. that's tangential to what they said though

[tardy moss]

yeah but to me there were not any specific reason given for doing this except that it "might" help performance

[crude mortar]

because it usually indicates a design flaw. Inheritance, when properly used, is not supposed to require that you know specifically which type of inherited class you are dealing with (assuming you are passing around the base class)

[rocky basalt]

No, I was asking "I'm doing this, is it bad for performance?"

[rocky basalt]

That's fair. I definitely never assumed it was a common thing to do

[crude mortar]

the reason it was likely a red flag was because this seems to be something you are doing often (every second or so), which means it might be part of your core game code

[leaden ice]

Because the whole point of polymorphism is not needing to know the specific underlying type when dealing with the parent type

[crude mortar]

and could turn into a larger problem down the road

[rocky basalt]

Gotcha

This is the only place I'm using inheritance in my codebase (well actually I'm not using it at all, still haven't implemented my 'idea').. for whatever reason inheritance feels like a problem waiting to happen

[crude mortar]

it usually is 😆

but you can definitely use it correctly and be effective with it

it is always somewhat of a difficult topic though, especially in game development where everything is so dynamic

keeping it simple is usually best

[rocky basalt]

a lot of beginning unity c# learning materials teach inheritance early on, which in my opinion is not the best use of time. i remember dabbling and quickly realizing it wasn't worth it

[crude mortar]

what is your current inheritance used for?

[shrewd mulch]

that doesnt give too good info

[tardy moss]

No offense meant it was simply my guess and I guess it was wrong about your intent. When you mentionned it I thought of doing that as well but in my case I thought it would be a premature optimization. Im going to have the same issues with premaking commonly used tiles for maps in my game

[rocky basalt]

In simple terms ClassA and ClassB are similar and can both be referenced by ClassC. I wanted to hold a list of ClassA+B in ClassC, instead of one list for each Class. Purely for streamlining <---- now that is likely premature optimization/OCD - haha- but I like to use these moments as learning opportunities

[crude mortar]

well what you would do, if using polymorphism correctly, is define the "similar" parts inside of a common base class, then override the similar parts if necessary in each derived class. Then, when iterating over the list, you wouldn't care which one (ClassA or ClassB) you are iterating over, because the functionality you need would be defined in the base class. You could also use an interface instead of a base class if that worked better for what you wanted.

[rocky basalt]

yeah, thing is ClassB's are sort of 'clusters' of ClassA so don't have much overlapping behavior. After my recent refactor I'm realizing I can probably get rid of all behavior in ClassB altogether tho, and have it simply be a data container of lists of ClassA.

But then I have to spend a few more hours refactoring. Wahh.

[leaden ice]

Definitely doesn't sound like inheritance was the right pattern here

[rocky basalt]

don't they always say there's multiple ways of doing things in programming 😅

[spring creek]

That is the danger, yes haha

[rocky basalt]

multiple 'valid' ways?

[crude mortar]

depending on how complex it is, there could be many many valid ways

[spring creek]

There certainly can be

[crude mortar]

it's really more of an art than a science most of the time, at the high level

[rocky basalt]

sure seems like it.

[warm kraken]

hey guys

i have an issue here

i have a ball with a rigidbody which i control with torque

the issue is that on one single collider

surface

it can be controlled smoothly

but whenever 2 colliders overlap (because im doing a lot of modular stuff)

[rigid island]

make a complete post before hitting enter..

[warm kraken]

it starts jumping up and reacting even tho those colliders are same height

so in the video i first test the ball controller on a modular surface

then in one surface

[rigid island]

video must mp4 cause its not working

[warm kraken]

oh sry

heres the mp4 version. i first test it on many overlapping surfaces and then with just a single one

[rigid island]

common issue

[warm kraken]

is there a way to solve this? perhaps an asset or something?

[rigid island]

yeah in 3D its even more fooked

"ghost collision"

you can try to maybe combine the dynamic meshes into 1 mesh

https://forum.unity.com/threads/ghost-collisions-on-adjacent-box-colliders.850951/

[warm kraken]

solved it by setting default contact offset to a lower value thank you for the help

[dense tusk]

ahoy lads. trying to formulate a thingy where i can call a method like such:

//psuedo-code
if (click on object)
{
  scriptOnObject.MethodToCall();
}

i have what i'm guessing is called an abstract class, and some scripts that inherit (i think that's the right term) from the class.
https://paste.ofcode.org/378PCYkiFdicXfYBLGSJugP //abstract class

//how the script above gets called
if (hit.collider.TryGetComponent<InteractScript>(out InteractScript t))
{
    interactScript = hit.collider.GetComponent<InteractScript>();
    interactScript.UseMethod();
}

my only grievance with this set up is that i have to make another script for each override i want to create. which is fine, but i wanted to know how i might achieve the same thing without making a new script for each one. maybe i don't even need to right now, i just don't know how to make it work in a single script ¯_(ツ)_/¯

[somber nacelle]

a few things, first what do you mean that you have to make another script for each override?
and also, you don't need that GetComponent call inside the if statement. you have a local variable t that the component reference is being stored in, just use that

[dense tusk]

oh facts. thanks

so the only way i thought i could make this work is to make the original script with the abstract class, and then make another script for the override methods and attach the script with override methods to an object.

[somber nacelle]

yes, you cannot instantiate an abstract class. so you need a concrete implementation that is not abstract. that is what you would attach to your gameobjects. your TryGetComponent will still get those other components that inherit from the abstract one since they are instances of the abstract class

[dense tusk]

gotcha. so with my current method, there's not really a way to do it without those concrete implementations in the form of separate scripts inheriting from the abstract one

[somber nacelle]

right, but i'm not seeing why that is a problem. that's literally how abstract classes work

[dense tusk]

you're right, its not. just trying to learn is all

i've messed around with unity events and i wasn't sure if maybe it would work similarly to that where it's kinda like a drop down of methods, so i was just checkin. i appreciate the explanation. i understand it more now

are there any other methods that can do something similar? this is the one i settled on, and it just happened to be the first one i learned about

[somber nacelle]

well your abstract class could be an interface instead since it's just a couple of abstract methods

[dense tusk]

those seem useful. thanks for the tip

is ignore collision from rigidbody an on/off toggle or a one time ignore ?

[lean sail]

what ignore collision are you referring to?

🤔 you're the one that asked "ignore collision from rigidbody". As far as im aware, rigidbody does not have anything named ignore collision

[round violet]

i mean to use ignore collision you need a rigidbody

i didnt mean it like a component parameter

        }

        foreach (Renderer r in floorTiles) {
            r.material = r.tag == "white"                              // And here
                ? wFloorMaterials[Random.Range(0, wFloorMatLength)]
                : bFloorMaterials[Random.Range(0, bFloorMatLength)];
        }
    }
}

Can anyone tell me why I'm getting an index outside bounds of array error on line 25?

[rocky basalt]

For my non-MonoBehaviour scripts, is there a need to attach them to GameObjects to make them work? Or can I simply create new MyScript script = new MyScript(), and reference/update that script via a List I add it to?

[deep oyster]

No it has not??? I'm succesfully getting this image in my start function, never deleting it, but now it says it doesn't exist???

[leaden ice]

Without knowing which line is 25, hard to say

[nimble cairn]

@leaden ice wallTiles[i].material = wallTiles[i].tag == "white"

The first line of the for, and foreach loop throw an error

[leaden ice]

I would guess wither wWallMaterials or bWallMaterials has a length of 0

So the random access in the ternary operator is accessing an invalid index of the empty array

[nimble cairn]

That was the case!! Does unity clear the array if I rename the variable??? I had previously allocated the materials and now in the inspector they have vanished.

@leaden ice +rep

Also, thoughts on the efficiency of the script? This just feels like it's the best way to handle a large amount of tiles for my levels.

[leaden ice]

Yes the serialized data will be lost since it has no idea that was supposed to be a the same array or something.

You're supposed to use [FormerlySerializedAs] when renaming serialized fields

[nimble cairn]

Good to know....

Thank you!

@leaden ice Just at a quick glance, what are your thoughts on the efficiency of the script?

[lean sail]

you cannot add a script to your GO directly if its not a mono. Yes you create them with new, but this code is gonna have to be done somewhere. That somewhere will eventually end up being a monobehaviour.

[rocky basalt]

I know you can't add it if it's not MB, I guess my question was more, do I NEED to make them MB's + add them to GO's to make everything run properly.

They don't use any MonoBehaviour functions, they're more like configuration/data containers

[nimble cairn]

@leaden ice And do you believe I should be using the for or foreach loops?

[leaden ice]

The use of tags is kinda janky and especially .tag is a known garbage generator.

But what's the efficiency concern about? Is this causing a performance issue?

[nimble cairn]

No, I use this script to randomize the material for my wall/floor tiles. Saves me hours of drag and dropping when building my levels.

I use .tag because the game is a "portal-like`` and I tag walls white or black to determine if the player can interact with them.

[leaden ice]

Tags are inefficient for this compared to an enum field or something on a component.

And especially the use of .tag is a known GC allocator

[lean sail]

itll be fine as a poco (plain old c# object), you do need one mono script that these poco's exist on

[rocky basalt]

cool cool. yeah i have a GameManager that creates them and holds the references and whatnot

[leaden ice]

Probably an #🔊┃audio question

[cold egret]

• Given a struct type that i deserialize fom json, will the instance of it be boxed by the time i get my hands on it? If so, then is there any way to escape allocations during the deserialization process?

Hello, anyone has experience with Unity Cloud code modules?
Trying to trigger a module function, which should sent notification to a player (from the push messages example), but receiving error:

[harsh root]

In Unity Vr I have an issue with rotation. I got an object with a configurable joint. When this object rotates. The child objects rotate in the oppisite direction

anyway to solve this?

[rancid jolt]

The character is moving fine, But when I am trying to rotate the body in the direction of movement. It is working but in a weird way.

Here is the full code

[stoic ledge]

Is there a way to exclude certain folders from build for certain platforms?
E.g. I have a Firebase Admin SDK and I want to include it only into the headless unity build.

[upper pilot]

Is there a reason why I should or should not use Events for all/most of my code in order to decouple my scripts?
i.e. if I want to hire a new party member, I dont want to directly call Party.AddMember(hero);
But instead I can do onMemberHired?.Invoke(hero);
Is that a better way? What is a downside?

Even tho all my scripts go through static Game instance:
Game.Instance.partyManager.AddMember(hero);

But they still directly call a function.

Should I at least do:

Game.Instance.AddMember(hero);

// Game script:
void AddMember(Hero hero)
{
    partyManager.AddMember(hero);
}

Tho even with events, if I subscribe to them I am still coupled somehow?
I guess in that case I can subscribe to those events with my Game class and call proper methods from it?

[latent latch]

Well, it depends how you want to set it up. If you call a method to insert this hero into the party, then you'd have to implement additional logic inside of this method to update those that are dependent on knowing this hero was added. Using events, you call the invoke and everyone listening onto this method will be notified, so they can use that info with their own internal logic to update any data.

[upper pilot]

Yeah but isnt decoupling about not having any connection to outside?

I.e. hiring manager and party manager dont know about each other existence

So I can cut them out into new project without needing the other script with me.

[latent latch]

events are good for decoupling or limiting what's passed around

but you could also use interfaces otherwise

[upper pilot]

So my current thought is to use a middleman to listen to all events and call proper functions)

How would I use interafaces in this case?

[latent latch]

The partymanager wouldn't have direct references to the party members, but an interface of implementation of each party member

IStats, ect

[upper pilot]

oh, but isnt that still coupling?

well kinda

[latent latch]

kinda I guess, but if you only have a part of the data it's not like you can use anything outside of IStats

[upper pilot]

Makes sense, I will have to play around with it.
I just want to avoid different modules talking to each other at all if possible

its getting out of hand already and we are not far in development 😄

Even tho I am using Events and trying to minimize coupling, but its not easy.

In some cases we just call a function directly from another module.

We do separate UI from code tho(using Events) which is good.

[latent latch]

usually events are my goto, but when you're dealing with monos you can't set them in the constructor, so it's not always like a true decoupling

usually you want to reuse monos anyway so not that big of a deal

[upper pilot]

Alright, thanks. I will probably need an UI manager of sorts that has an "Init" function that I can call when my Game is loaded right?
Otherwise I have trouble with order of execution and I cant subscribe to events which dont exist yet.

Maybe I do it wrong tho hmm

I might need to new() events in Awake, and subscribe in Start

[tired aspen]

I have list that is from type BlockPositionClass

public class BlockPositionClass
{
    public Vector3 vector;
    public int myInt;

    // Beispielkonstruktor
    public BlockPositionClass(Vector3 vector, int myInt)
    {
        this.vector = vector;
        this.myInt = myInt;
    }
}

Now i want to delet an element. (newBlockPosition)

            // Erstelle ein neues BlockPositionClass-Objekt
            BlockPositionClass newBlockPosition = new BlockPositionClass(currentGridPosition, blockType);

            Debug.Log(newBlockPosition.vector);
            Debug.Log(newBlockPosition.myInt);
            blockPositions.Remove(newBlockPosition);

But when i try this nothing happened.
And I already teste if the numbers are wrong(currentGridPosition, blockType) but they are correct.

[latent latch]

Managers, or anything that aren't dependent in awake(), everything else in start. There's also the custom execution ordering in the settings.

[upper pilot]

and I need to Initialize game data after Start is done executing uh this is hard <_<

I tried the custom execution and it didnt seem to work for me, but I will have to find a way to load things in some order i.e.

• setup events first
• subscribe
• load data
• invoke those events

[cosmic rain]

Did you actually add it to the list before removing it?

[tired aspen]

yeas

[cosmic rain]

Then maybe share the whole code?

[tired aspen]

this is the code where i add the block to the list.
First I place the object in my project, it gets added to the list but when try to delete the block it just stays in the list.

 private void placeObject(BuildingObjectBase obj)
    {
        if (escapeMenu.InEscapeMenu) return; // wenn im escape menu dann soll alles aus sein

        if (!GroundMap.GetTile(currentGridPosition))
        {
            if (CantBuildOutsideTheBorder(currentGridPosition)) return;
            
            GroundMap.SetTile(currentGridPosition, obj.TileBase);
            HandleDeselection();
            getsObjectsGridPostion(currentGridPosition);

            //Checks if what the tile that was placed was
            int blockType = -1;

            if (GroundMap.GetTile(currentGridPosition) == tile1)
            {
                blockType = 0;
            }
            else if (GroundMap.GetTile(currentGridPosition) == tile2)
            {
                blockType = 1;
            }
            else if (GroundMap.GetTile(currentGridPosition) == tile3)
            {
                blockType = 2;
            }

            blockPositions.Add(new BlockPositionClass(currentGridPosition, blockType));
        }
    }

 private void deleteObject()
    {
        if (escapeMenu.InEscapeMenu) return; // wenn im escape menu dann soll alles aus sein

        if (GroundMap.HasTile(currentGridPosition))
        {
            //Checks if what the tile that was placed was
            int blockType = -1;

            if (GroundMap.GetTile(currentGridPosition) == tile1)
            {
                blockType = 0;
            }
            else if (GroundMap.GetTile(currentGridPosition) == tile2)
            {
                blockType = 1;
            }
            else if (GroundMap.GetTile(currentGridPosition) == tile3)
            {
                blockType = 2;
            }

            // Erstelle ein neues BlockPositionClass-Objekt
            BlockPositionClass newBlockPosition = new BlockPositionClass(currentGridPosition, blockType);

            Debug.Log(newBlockPosition.vector);
            Debug.Log(newBlockPosition.myInt);
            blockPositions.Remove(newBlockPosition);

            // Entferne es aus der Liste, wenn es bereits existiert (optional)
            /*int index = blockPositions.IndexOf(newBlockPosition);
            blockPositions.RemoveAt(index);
            Debug.Log("Dleete");*/

            GroundMap.SetTile(currentGridPosition, null);
        }
    }

[upper pilot]

You are trying to remove a block position you just added on the same line of code

            // Erstelle ein neues BlockPositionClass-Objekt
            BlockPositionClass newBlockPosition = new BlockPositionClass(currentGridPosition, blockType);

You made a new instance here then you delete it.

[cosmic rain]

This tries to remove a totally different object(not the one you added). Classes are reference types and they are compared by reference.

[upper pilot]

Make a function that returns BlockPositionClass instance based on your coordinates.(a foreach loop might do, compare grid position and block type then return it)

Tho I am sure there are better ways to do it, but this will work too.

            BlockPositionClass blockInstance = GetBlockInstanceAt(currentGridPosition, blockType);
            blockPositions.Remove(blockInstance);

[tired aspen]

But than i have another question

int index = blockPositions.IndexOf(newBlockPosition);
            blockPositions.RemoveAt(index);

and then why doesn't it work?
that gets the specific index

[upper pilot]

Because newBlockPosition was just created, its different from the one you placed earlier.

            BlockPositionClass newBlockPosition = new BlockPositionClass(currentGridPosition, blockType);

This code makes a completely NEW instance of a block class, it has nothing to do with the one you created inside "placeObject" function

You need to search your List in a foreach loop(or regular for loop) and find the block you want.

[tired aspen]

            BlockPositionClass newBlockPosition = new BlockPositionClass(currentGridPosition, blockType);

            BlockPositionClass itemToRemove = null;

            foreach (BlockPositionClass item in blockPositions)
            {
                if (item.Equals(newBlockPosition))
                {
                    itemToRemove = item;
                    break;  
                }
            }

            if (itemToRemove != null)
            {
                blockPositions.Remove(itemToRemove);
            }

i used this thanks for the help. ^-^

[upper pilot]

This shouldnt work -.- Why are you still doing new

Equals might simply compare the type, not sure, but the code above shouldnt work as its the same thing as before right?

            BlockPositionClass newBlockPosition = new BlockPositionClass(currentGridPosition, blockType);

Delete this and dont use it when deleting stuff from the List.

foreach (BlockPositionClass item in blockPositions)
{
    if(item.positon.x == currentGridPosition.x && item.y == currentGridPosition.y && item.blockType == blockType)
    {
      blockPositions.Remove(item);
      break;
    }
}

You need this if statement to find an item

There is no other code needed.

[tired aspen]

ok

[upper pilot]

Ideally you put it into a function and do return item; so you can remove it elsewhere since that function could be useful for other things later.

[tired aspen]

thanks for the idea

[placid compass]

Hello, I have a question.
I have a character that uses Character controller for movement. I also have a object pick up mechamic. So when I pick up the object and walk around with it it just goes thru the walls even tho it has a collider. I tried adding another collider to the player that turns on when the object is picked up but it still goes thru the wall. The character stopps when the character controller collider hits the wall but not when any other collider does. Any idea how I can solve this? Thanks

[wicked berry]

currentScene = SceneManager.GetActiveScene();
StringSave = currentScene.name;

why does this doesnt return me a string?

[placid compass]

it does

[deft timber]

if you need to modify the anchoredPosition then just modify it, what's the problem?

.anchoredPosition

Vector2 screenPoint = RectTransformUtility.WorldToScreenPoint(Camera.main, worldPosition);

Vector2 anchoredPosition = transform.InverseTransformPoint(screenPoint);

[thick socket]

super late reply...but how to you make sure you are grabbing/using the right key?

    public DamagePopup pfDamagePopup;

   public void ShowText(Vector3 position, int damageAmt)
    {
        DamagePopup damagePopup = BasicPooling.instance.BasicPool[pfDamagePopup].Get().GetComponent<DamagePopup>();
        damagePopup.Create(position, damageAmt);
    }```

public Dictionary<Component, ObjectPool<Component>> BasicPool = new();
    [SerializeField] List<Component> items;
    public static BasicPooling instance;

code doesn't work because "key doesn't exist"

if I open prefab and drag in the script it creates fine

however when I try to release it inside of the DamagePopup Script it throws and error for "can't find key" also

BasicPooling.instance.BasicPool[this].Release(this);

System.Collections.Generic.Dictionary`2[TKey,TValue].get_Item (TKey key)

[leaden ice]

Well this is an instance of the prefab in this case, right?
Whereas the BasicPool dictionary is using the prefab itself as the key, yes?

[thick socket]

correct

shouldn't the component be the same though?

[leaden ice]

so you'll need a reference to the prefab

[leaden ice]

no, the instance is a copy.

the prefab is the original

[thick socket]

oh I gotcha, that solved it thanks!

[thick socket]

How do I "pick" which component goes here?

Anytime I try and drag in a prefab do I need to open the prefab in another inspector and grab the component that I need to be the key?

[leaden ice]

right click the pfDamagePopup object in the scene and select "Properties.."

that will open a separate special inspector for it

then open this pool thing and you can drag the title bar of the specific component in.

[thick socket]

awesome thanks!

[steep herald]

Has unity developed a haptics library for mobile yet?

[deft timber]

haptics library for mobile? wdym

[simple sable]

Hey everyone, I have a quick question.

By using "[RequireComponent(typeof(Light2D))]" I make sure that the gameobject my script is attached to will also have a Light2D. But, is there a way make it so that I can't (by mistake) disable the Light2D?

[leaden ice]

Nope

Are you worried about disabling it in the inspector or in code?

If you're worried about the inspector you could use OnValidate to check if the light has been disabled and enable it or print a warning message

[simple sable]

Yeah. I also have this script that doesn't have the checkbox, but I'm not sure why.

[simple sable]

That's a good idea.

[icy schooner]

Its because it doesnt have any methods that will be called by itself I believe

[leaden ice]

The checkbox only exists if you have one of the functions that cares about it being enabled, such as Start or Update

[icy schooner]

Yeah that

[simple sable]

Ohhh.. I see.

Thanks for the help!

[spring creek]

The inverse of what they're saying is also important. Disabling a script will not stop all code from running
Only unity messages

[round violet]

Except in c# script is there a way to do childs of prefab or stuff ?

Like create a child of a Actor BP in UE (if anyone knows)

[spring creek]

Not sure what you mean. You can drag an object onto another and it will make it a child..
Is that what you're talking about?

[round violet]

When i am saying child i mean it in the "class" code concept

[spring creek]

Oh, then no. It would be done in code
Inheritance is purely in code

[round violet]

Sad

Ty for the response

[hexed pecan]

Prefab variants might be what you want

A prefab variant can 'inherit' everything from another prefab and then you can modify the variant as you like

[round violet]

Oh nice

Is it built in?

@hexed pecan (forgot to respond)

[spring creek]

Prefab variants are built in, yes

Won't make child classes, it will make variants of the gameobject to use.
They are very useful

[heady iris]

Can I check how much time is being spent waiting for the target FPS?

I am writing some code to automatically set the render scale. Currently, it just lowers the scale if the FPS is too low and raises it if the FPS is too high. This is causing some annoying "wobbling" as it goes up and down, so I'd like to change it.

My new strategy is going to be to only use a few increments -- 100%, 80%, 60%, etcetera. I want to change increments only after the FPS has gone out of range for too long. This is easy if the framerate is too low.

But if Application.targetFrameRate equals the framerate my scaler is trying to maintain (let's say 60), the scaler will never see the FPS going much above 60.

I figure I could just check how much extra time each frame has, and raise the scale if there's lots of spare time

Alternatively, a better strategy for picking the render scale would also help me out here :p

[heady iris]

They're a godsend for making a consistent UI

[round violet]

I looked in the docs its exactly what i wanted ty

[heady iris]

All of my various settings-menu entries are variants of a single "setting entry" prefab

[polar marten]

are you aware there is a built in unity feature for this?

[round violet]

Yeah in UE all my UI is class child based xD

[heady iris]

this is specifically in the HDRP, if that matters

Unity triggers this scaling if performance data suggests that the frame rate is about to decrease as a result of the application being GPU-bound.

this sounds promising

Ah, I see that FrameTimingManager can tell you how much frametime is gpu-based

[polar marten]

you don't have to manage this yourself. you can check a few boxes, and you will have enabled dynamic resolution scaling in hdrp

is that your objective?

[heady iris]

yes, I want to have an option to make the render scale auto-adjust

I am currently controlling the dynamic resolution scale myself

[polar marten]

it's not clear to me what is missing from unity's built in feature for you

[heady iris]

I do not know where these boxes are.

[polar marten]

https://chat.openai.com/share/8f8428ba-9f0c-4414-9954-b8506b7fa178

[heady iris]

I am aware of how to use HDRP's dynamic resolution scaling. I was not aware of how to make Unity automatically adjust the scale to maintain a target framerate.

I just noticed the HDDynamicResolution component, which is what I need

[waxen jasper]

I need to channel more brain power on this one. I posted in machine learning channel but you don't need to understand ml agents to understand what I'm trying to solve. Essentially I'd like to get an average location of all the body parts and determine if the velocity of that is moving in the direction of the target.

Hey so training my 2d rigidbody stick figure guy. any body have any suggestions on how I can reward it for moving towards the target? the dot approach works best but Is there a way i can get an average of all the body parts, if you get what I'm trying to say. Right now the stick figure immediately leans towards the target at a 45 degree angle.

            // Calculate the dot product between the agent's velocity and the direction to the target
            float dot = Vector2.Dot(
                spine.gameObject.GetComponent<Rigidbody2D>().velocity.normalized,
                toTarget.normalized
            );

            // Reward the agent if the dot product is positive (i.e., moving towards the target)
            if (dot > 0)
            {
                HandleReward("dot", 10f);
                AddLabel("dot", dot);
            }
            // Punish the agent if the dot product is negative (i.e., moving away from the target)
            else
            {
                HandleReward("dot", -12f); 
            }

[leaden ice]

to get the average of vectors you just add them all up and divide by the number of vectors

same as basically any quantity

[polar marten]

https://github.com/Unity-Technologies/DynamicResolutionSample/blob/main/DynamicResolution.cs

you should use this script

[waxen jasper]

Awesome! thanks

[heady iris]

I would find the average momentum, not the average velocity

[polar marten]

i am not sure why this isn't delivered in the hdrp package

but this will correctly achieve what you want

[heady iris]

It is, in a similar form, as HDDynamicResolution

I missed it when reading the docs the first time.

[polar marten]

ah i see, they do put it in the package

sorry about that

that must be what i was remembering

[heady iris]

Momentum tells you which way the object is moving overall

[prisma yacht]

I'm trying to rotate a 3rd person character using the mouse like this:

        float mouseXInput = Input.GetAxisRaw("Mouse X");
        rotationY += mouseXInput * mouseSensitivity;
        Quaternion localRotation = Quaternion.Euler(0f, rotationY, 0.0f);
        transform.rotation = localRotation;

but the rotation only happens when the cursor is moving

I want it to rotate continuously

[polar marten]

first you should be using isaac gyms

[heady iris]

If you want to use pointer position, not pointer movement, you need to change how you're reading input

Mouse X is how much the mouse has moved

[prisma yacht]

input.mousePosition then?

[heady iris]

Describe how you want the camera movement to work.

[waxen jasper]

I don't see a unity doc on momentum?

[heady iris]

There's no momentum property, but it's just velocity * mass

[polar marten]

i am not sure what is going on here, but i think you want to reward decreasing distance to target over short periods of time, not the velocities of individual body parts

[heady iris]

and yes, you should reward that

[polar marten]

@waxen jasper the approach you are taking with velocity is wrong.

[heady iris]

Instantaneous velocity or momentum might be going the wrong way from time to time

but this shouldn't be punished

imagine trying to climb stairs without your center of mass ever going down

[frosty token]

I'm for help with quarternion rotations, i've tried for over a year to get this right, but i keep finding edge cases that ruin a very fundimental part of my game. I've made a small separate project that should illustrate the issue. While the rigidbody is under torque the plane will not only turn on the local z axis, but also turn through the y-axis. I don't understand why. I hope the image helps with what i'm trying to achieve. The left is a "normal turn" by the player. However, it should also be possible (at any point) to flip the plane over. Note that the game is 2.5D and all movement on the x-axis is locked. Basically i want to be able to angle the plane on the x-axis only, and rotate the plane on the z-axis only. You will receive a free copy of my game if I manage to solve this haha.

    void FixedUpdate()
    {
        currentSpeed = Mathf.Clamp(currentSpeed, 0f, maxSpeed);

        Vector3 pos = transform.position;
        pos.x = 0f;
        transform.position = pos;
    }

    void OnDrawGizmos()

[prisma yacht]

I guess just like a first person camera, where the camera moves a constant amount left or right if you move your cursor left or right

regardless of where the cursor is

[leaden ice]

Just a note - * Time.deltaTime is not appropriate inside AddTorque (or AddForce)
AddTorque already incorporates Time.fixedDeltaTime automatically.

[heady iris]

I don't understand the problem, then.

The camera should only move when you move the mouse.

[gleaming blaze]

hi everybody

public abstract class Fadeable : MonoBehaviour
{  
    public virtual async void ChangeCurrentByDayTime(DayTime dayTime, CancellationToken token) 
// if Application.exitCancellationToken.IsCancellationRequested => method must stop. how can i do this?
    {
        await FadeIn(token);
        
        ChangeTextureByDayTime(dayTime);
        
        await FadeOut(token);
    }
    public virtual async Task FadeIn(CancellationToken token)
    {

    }
    public virtual async Task FadeOut(CancellationToken token)
    {

    }
    public abstract void ChangeTextureByDayTime(DayTime dayTime);
} 

[prisma yacht]

when the cursor hits the edge of the screen it won't rotate

[heady iris]

oh, that's the problem

[gleaming blaze]

help me with this problem 😦

[heady iris]

sounds like you want to lock the cursor

[frosty token]

sloppy indeed, slipped in with the AI suggestions haha

[polar marten]

I'm for help with quarternion rotations

[waxen jasper]

But won't it just run back and forth theoretically if there isn't a loss for going the wrong way? Edit: and actually navigating something like stairs will be later. good point though, might need to add ai navigation with checkpoints for that

[prisma yacht]

I don't know that i can do that because it's webGL

and I don't think it lets you lock cursor once it's built into a webGL window

[polar marten]

a single episode should be a full uninterrupted attempt to get to the destination, not a frame

[heady iris]

https://docs.unity3d.com/Manual/webgl-cursorfullscreen.html

[gleaming blaze]

how to make the asynchronous method react to the fact that the token sends a cancellationRequest and stops?

[heady iris]

you just have to do it in response to interaction.

[prisma yacht]

oh ok

[polar marten]

you can catch an OperationCancelledException. any awaits that receive the token will throw it, within the body of the task being cancelled

[leaden ice]

According to https://learn.microsoft.com/en-us/dotnet/api/system.threading.cancellationtoken?view=net-8.0#examples
You would have your code use Try/Catch and catch a TaskCanceledException

[prisma yacht]

ok but I guess the problem I'm having is the fact that if you put your cursor to the left, it should continue to rotate forever

until you bring it back to the center

[leaden ice]

Either that or you can read the token for this https://learn.microsoft.com/en-us/dotnet/api/system.threading.cancellationtoken.iscancellationrequested?view=net-8.0#system-threading-cancellationtoken-iscancellationrequested

[heady iris]

Okay, so you don’t want a locked cursor, and you want something more like a joystick.

I’ve been having a hard time understanding what you’re asking for!

[prisma yacht]

yeah sorry, it's been a while since I've worked with 3d games

[heady iris]

Subtract the center of the screen from the mouse position to get a vector

Use that to decide how to rotate

[prisma yacht]

I don't really understand this part

[heady iris]

Suppose the mouse is at [300,200] and the center of the screen is at [400,200]

The difference is [-100, 0]

So your mouse is to the left of the center. You should rotate left.

[waxen jasper]

Any reference to a better approach would awesome. It does manage to get there but not optimally. Not the best performing example but I'm training another rendition at the moment lol

[swift falcon]

can anyone help me? this code right here is responsible for freezing my unity editor 2 times

[simple egret]

Infinite while loop

[swift falcon]

yea but how

[simple egret]

Your objects are destroyed at the end of the frame when you call Destroy(), except the end of frame is never reached because that loop is executing

You should be using a for loop to go through all children of the object

[swift falcon]

oh yea thats genius

ty

[hexed pecan]

You can also do foreach(Transform child in targetParent.transform)

[swift falcon]

new approach, also added .gameobject at the end since it gives me an error

[swift falcon]

i could

its a little more optimized memory

[simple egret]

"an error" - mind reading is not installed on this computer. Please state the error

[swift falcon]

it doesnt know what to delete, so i told it to delete the gameobject

[simple egret]

Yes you indeed cannot destroy a Transform

[swift falcon]

lemme see

[simple egret]

The for loop loops too much

[hexed pecan]

Yeah, the <= should be <

[swift falcon]

i wonder why

[swift falcon]

i thought it wont delete the final object

[hexed pecan]

First object is 0

5th object is 4

Etc.
So the last item in an array is always count - 1

[swift falcon]

yay it works perfectly

[swift falcon]

imma do it like this, so the i variable is now child or what

[hexed pecan]

There's no variable i now, you work with child directly

Just Destroy(child.gameObject)

[swift falcon]

knew it, thanks

[hexed pecan]

Both ways work - I just find foreach cleaner here

[swift falcon]

it uses a little less memory i think

and yes its cleaner

[hexed pecan]

Not really. Generally foreach has worse performance than for
But these days the difference is so miniscule you might as well ignore it

[pine carbon]

void Update(){
    
    if (Input.GetKeyDown(KeyCode.Space)) {
        Vector3 torque = rb.GetAccumulatedTorque();
        rb.AddForce(new Vector3(
             torque.z, 0, torque.x
        ).normalized * jumpForce, ForceMode.VelocityChange);
        rb.AddForce(new Vector3(0, jumpForce, 0), ForceMode.VelocityChange);
        Debug.Log(torque);
    }
}

i used this code to make the ball jump in the direction its rolling but it works different sometimes

[hexed pecan]

Not sure why you are using accumulated torque for the force

[pine carbon]

to make the ball jump in the directions its rolling

[hexed pecan]

Try using rb.velocity to get the direction instead?

[pine carbon]

its same

oh wait a second

[hexed pecan]

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

The accumulated torque is reset during each physics simulation step.
I wonder if this is a problem since you are in Update

[pine carbon]

it works wery well now thankyou

[gleaming blaze]

wow, thx

you've really helped me

[swift falcon]

why does it give me this error

[leaden ice]

newAnswer.Instance is null

assuming the highlighted line is line 45

btw C# convention is for class names is to use PascalCase, not camelCase

[swift falcon]

ok

[swift falcon]

its not

[leaden ice]

This code assumes that Awake is actually running

[swift falcon]

i set its value in awake()

[leaden ice]

it won't run if you don't actually have an active instance of this script in the scene

[swift falcon]

wdym

[leaden ice]

If you don't have any object with the newAnswer script attached to them in the scene, the code won't run

naturally

[leaden ice]

Another possibility, if you DO have such an object in the scene, is that the other code is running BEFORE this Awake code does.

[swift falcon]

i thought of that

how do i fix

[leaden ice]

Show the full stack trace for this error

[leaden ice]

Can you show the code with line numbers?

[leaden ice]

Also which object have you selected here that we're looking at? is this an object in the scene?

[swift falcon]

yea

[leaden ice]

Ok it's the NEXT line

[spring creek]

It's best to not crop things so much btw. It would be helpful to see more of the editor than just those small snippets

[leaden ice]

not the one you originally showed. You misled me about which line it was

look at liune 45

it's either Answer.instance that's null or questionObj

questionObj seems quite likely since you're using GameObject.Find for some reason

That's incredibly flimsy

[swift falcon]

does gameobject.find attribute it asyncronisely or what

[leaden ice]

What?

Asynchronously?

[swift falcon]

like at the end of the frame

[leaden ice]

No, it's just really flimsy because the object name has to match perfectly

and has to be active

Why not just use direct references etc

[swift falcon]

can i get a child of an object that has a specific name

[spring creek]

Is the name of questionObj just a plain number? Because that is what you seem to be searching

[swift falcon]

like without atributting it in inspector

[swift falcon]

its a gameobject

[spring creek]

Just don't use names at all honestly. Really bad way to dobthis

[spring creek]

Yes I know, not what I was asking though

You are searching for objects called "1" "2" etc

[leaden ice]

sure that's what Transform.Find does, but still better practice to use the inspector

[swift falcon]

i cant use the inspector since that value changes

[swift falcon]

exactly

[spring creek]

So that is what they're named?

[swift falcon]

yes exactly like that

[leaden ice]

what value changes?

[spring creek]

Ok, good, but also terrible haha
Don't use names for this. It is so error prone

[swift falcon]

the game object changes from the object named 1 to the object named 2

[leaden ice]

You need to learn to use arrays. There is no need to use object names and Find for this

[swift falcon]

then how

[swift falcon]

like lists

[spring creek]

Lists are different than arrays, but sure

[swift falcon]

wdym by arrays

[leaden ice]

Arrays are the most basic collection type in C#

it's a collection of multiple objects in one variable

[spring creek]

The things in c# called arrays

public int[] myIntArray

[swift falcon]

isnt lists somehwat the same

[spring creek]

Somewhat yeah. They use arrays internally

[leaden ice]

Lists are sort of like an extension on arrays that allows them to grow and shrink. Arrays are normally of a fixed length

[terse turtle]

I'm currently trying to create a working door with my Tilemap Door. However, I don't think there is a way to do that. So I did the next best thing and will be using a sprite door that replaces the Tilemap Door on the Grid. I want to know if this is the only way and how should I go about doing so?

The Game is TopDown 2D and the player can see the door like in the Picture. I want to make the door open and then able to walk into. Then Teleport to a new scene.

Whoops didnt mean to delete me other message but anyway why would that be more optmised?

Tiles are annoying to move around and managing multiple grids is annoying too

[terse turtle]

I saw a notification but I don't see where it came from. Did someone send me something?

Are you helping me?

Next time @ me please

I'm a bit confused on what you are trying to tell me here.

Is there a way to use sprites with Tilemaps?

Because the way I was going to do it is this: Create a Door Sprite with Animator/Animations. I simply just cover the empty tile that the door was supposed to go in the Tilemap, but since I am using a Sprite I would just move the Sprite Door there instead.

Yes, that's why I was in need of help.

If this is possible then I would like to know how.

[wind needle]

Hi! I have a question about the context of coroutines:

I have a coroutine that creates a game object, and sets the parent to the current components game object.

I have created a method in that same component that simply starts the coroutine:

void CreateStuff() {
  StartCoroutine(CreateStuffCoro());
}

IEnumerator CreateStuffCoro() {
  var o = new GameObject( ... );
  o.transform.SetParent(transform, false);
}

However, when I call this method from another component (attached to another game object), the new game object is added as a child of the caller gameobject, instead to the gameobject of the component that has the above methods! What is the logic here?

[terse turtle]

This is a lot of Information to take in. I should note that I've never used Tiles in code, so all of this is very confusing.

Thank you.

By setting, do you mean when I paint the Tiles?

What is ref? A reference?

[kind panther]

does anyone know shader graph??

[terse turtle]

That complicates things even more for me. Is there a very simple explaination that a begginer can understand?

[kind panther]

im trying to pixelate an img but i want to have a limit of colors(like 10) to the final image,any ideas how?

[terse turtle]

I'm confused on "ref". Does it matter alot here?

[leaden ice]

#archived-shaders

[kind panther]

mb

[terse turtle]

No.

Will I be able to the Door Functionality without using my own custom Classes/Ref?

Also, that makes better sense to me*

So the value is changed to 4, but the "int" doesn't get effected?

Or the int's Value is moved but not the actual int. Which means int still stays where it was but the value gets taken.

[hardy tendon]

hi, does anyone here know anything about XR or VR in general?

[spring creek]

#🥽┃virtual-reality

[polar marten]

your reward is the -(destinationPosition.x - characterPosition.x) per episode

that is the simplest and best approach

[leaden ice]

only the myInt local variable inside the ChangeMyIntPlease function is changed. And that variable stops exsiting when the function ends because it's a local variable. (function parameters are local variables)

[polar marten]

Any reference to a better approach would

[terse turtle]

Okay. But is this to help with door? Because it just seems like I'm learning how variables work?

[hardy tendon]

thanks

This is becoming a long conversation. Is there a way to make a thead so that I can go back to the conversation if I forget something?

I tried it. Its too messy

im trying to have a ball go around my world randomly and when i run this it doesnt do anything and i dont know why. can someone help me with this ;-;

[zinc parrot]

Hey how does unity do its motion vectors? I notice that objects spinning very fast can add to the motion vectors even if they are completely occluded
for example this sphere is spinning very fast, but its also completely behind another object
it dissapears if I get closer
unity builtin 2021

oh wait its only happening if the near field isnt minimum
well happens less if I am closer or the near field is further

[idle mason]

trying to load a prefab directly, though when I try calling upon smth when its hierarchy it doesnt seem to find it, any ideas?

(the method im actually using for getting the child)

[leaden ice]

This is not how Resources.Load works

[idle mason]

I see, how should I be using it?

[leaden ice]

Read the docs especially the part about how the path should be and where the file needs to live:
https://docs.unity3d.com/ScriptReference/Resources.Load.html

[sleek spoke]

I have a simple object pooling system.

To make sure that pooled objects aren't getting destroyed instead of recycled I have added an assert to OnDestroy that will fire if a pooled object is destroyed before having OnApplicationQuit invoked. Here's a screen-shot of the relevant code.

However, this assert fires sometimes when exiting play-mode in the editor.

Anyone know why this might be happening?

[leaden ice]

Beyond that, reaching into the hierarchy of the prefab like that is poor practice.

[leaden ice]

Because the scene is unloaded and therefore all the objects in it are destroyed when you exit playmode

using OnDestroy for this isn't the best idea

[sleek spoke]

Do you have a suggestion for how to do this better?

[leaden ice]

not really tbh. I just wouldn't worry too much about it

You'll know you have an issue if you get MissingReferenceException in your pool.

[idle mason]

ive looked at it, i added the file type, though it still doesnt seem to be loading properly

[leaden ice]

you didn't read it properly. You explicitly don't want the filetype, and there are other requirements.

[sleek spoke]

Hmm... thanks for explaining what's going on at least. That makes sense. I'd like to find a way to error as soon as someone tries to delete a pooled object to prevent needing to go hunting.

[spring creek]

One of the big things you're getting wrong is WHERE the file is located
Resources load from the Resources folder, not Assets

[idle mason]

I see

well ive now set it to work from the file path from the folder its stored in, but again, it doesnt appear to be working h

I stored them in the same folder, I can move it back if need be but this is what im working with

[spring creek]

Is the folder called Resources?

Wait, you put it in the root project folder? There is no path there

[leaden ice]

wdym "the same folder"?

Show where the prefab lives

[idle mason]

...im assuming i have to put them in different folders

[leaden ice]

no

you still seem not to have read the docs

they spell out clearly where to put the asset

[spring creek]

I also spelled it out twice now.
Resources folder.
Literally a folder just named "Resources".... it is a requirement. It will not work otherwise
That folder can be just about anywhere, but it needs to be named that, and you have to include the whole path in the load function

[idle mason]

there, i fixed it

[spring creek]

The fourth paragraph down in the docs is VERY clear

[frosty token]

I think i can rephrase my question a bit now that I understand the issue better. How would I avoid having any rotation on the Y-axis? or if it is unavoidable, how would I make sure that the "nose" of the plane is "glued" to y-axis=0? Thanks for your help!

        currentSpeed = Mathf.Clamp(currentSpeed, 0f, maxSpeed);
        rigidbody.velocity = transform.forward * currentSpeed;

### the _combination_ of these forces will rotate the y-axis, i want to roll in z and pitch in x at the  same time without leaving the y-axis
        rigidbody.AddForceAtPosition(Vector3.down * rotationSpeed / 4f * Input.GetAxis("Horizontal"), transform.position - Vector3.forward);
        rigidbody.AddTorque(transform.forward * flipTarget * rotationSpeed / 10f);
### 
        // reset the x position
        Vector3 pos = transform.position;
        pos.x = 0f;
        transform.position = pos;

[leaden ice]

Brute force cheeky solution to start with:

void FixedUpdate() {
  Vector3 forward = rb.rotation * Vector3.forward;
  Vector3 up = rb.rotation = Vector3.up;

  forward = Vector3.ProjectOnPlane(forward, Vector3.right);
  rb.rotation = Quaternion.LookRotation(forward, up);
}```

[long glacier]

hello there, is there an equivalent to
[ExecuteInEditMode]
but start and not update in edit mode?

[leaden ice]

you could do something like:

void Update() {
  #if UNITY_EDITOR
    if (!UnityEditor.EditorApplication.isPlaying) return;
  #endif
}```

kinda weird to have only Start in edit mode imo though

maybe you want OnValidate or OnReset?

[long glacier]

you mean start?

void Start() {
  #if UNITY_EDITOR
    if (!UnityEditor.EditorApplication.isPlaying) return;
  #endif
}

[leaden ice]

I misunderstood your question if this is what you want, but sure.

[cobalt jackal]

So... öhm... I got a problem... I would rly like to know what is bloating this file that much (about 1-2h of working) but after 30m I cant get it to open... trying to split it fails as well... I... I am a bit lost 😄

Its the Unity editor log

[frosty token]

Try notepad++, it can open pretty much anything

[leaden ice]

if this was unix I would suggest to use tail

since you're on Windows you can download an application like https://www.baremetalsoft.com/baretail/

You will need something special because it's not a good idea to load an entire 12GB file into memory

these applications can load only a portion of the file.

If you don't care about the contents, just delete the file!

or just delete it anyway and reproduce whatever the issue is

[frosty token]

or you can use git bash which will have tail as well most likely. Or WSL2 if you have it installed, it'll be mounted under /mnt/c/Users/...etc

[leaden ice]

sure that's an option if you have a unix subsystem or equivalent e.g. git bash^

[frosty token]

still, that notepad++ will stream the file, so scrolling around

[cobalt jackal]

damnit

[frosty token]

nooooooooo

[cobalt jackal]

I would like to read like idk... the last 10.000 lines to see what is bloating so much

cause... I have 0 idea...

I got no manual function writing excessive logs in my unity application

[leaden ice]

sure the tools I mentioned above should be able to do that for you.
Or, again, you could just delete the existing file, do some stuff, and check on the new presumably smaller file

[frosty token]

you'll have Git Bash installed if you have Git for Windows , enter this in that command prompt tail -n1000 "C:/Users/marco/AppData/Local<fullpath here flip the slashes"

[cobalt jackal]

yeah... just got it working like 30 secs ago 😄

~95% of the doc seems to be this?

dafuq

[frosty token]

looks like ar VR plugin, Varjo XR Plugin for Unity, try uninstalling it if you're not using it

whoops wrong reply sorry

[cobalt jackal]

I am looking into that now... I need that plugin though... but... I think its broken like this...

thanks for helping me getting it open though!

rest I can probably fix

So... fixed it (for now) thanks for the help!!! - well... this is what happens if you try to develop from home without having a full setup 😄

[tidal shadow]

i have this jump method, only being called in 1 single place which is inside of fixed update
the first if statement executes just fine
but the second one that detects if i let go of space, does not seem to run
anyone have any idea to why?

out of 5 times i let go of space, only 1 of those triggered and outputted to the console

[leaden ice]

input handling is not supposed to be in FixedUpdate

Input handling goes in Update

FixedUpdate doesn't run every frame, so it will miss things like GetKeyUp most of the time

btw 20 * Time.deltaTime in FixedUpdate is just always going to be 0.4

[tidal shadow]

oh yeah true
fixedupdate is for physics only

[tidal shadow]

that cant be true can it?
there is deltaTime and fixedDeltaTime or whatever its called
2 different things

[leaden ice]

deltaTime inside FixedUpdate always just returns Time.fixedDeltaTime

Second sentence here https://docs.unity3d.com/ScriptReference/Time-deltaTime.html

[tidal shadow]

wow, so thats a little shortcut

[shadow nacelle]

Okay so, I been making a game with a group of people (for a class assignment) and I need a bit of help on some of my scripts and is just wondering if anyone can help me out. So, right now I'm trying to figure out how to spawn 3 different food items on 3 different counters using a counter code I have. (I have many more problems but I'm trying to go step by step)

And here’s the code my teacher made

But I have almost zero clue how to actually utilize it to get the 3 desired items for each counter

And the whole goal is to get those 3 items to spawn so when I pick one up it goes on a 3 second cool down and spawns the desired food back

[lean sail]

First !code on how to format it properly,
2nd what 3 items are you referring to? You have a single string named item, which will be kinda useless by itself
3rd your teacher made this? It's pretty bad..

Well the three food items are supposed to be burger, fry, and smoothie, and in his defense he doesn’t know much about unity and uses unreal.

[lean sail]

I meant more like where are these items that you are trying to spawn? Are they just prefabs, does some script hold a reference to the prefabs?

[lean sail]

One good change to do now is change the invManager to type InvManager instead of game object. Then just drag the object containing this script into the same inspector slot. No need to call GetComponent every single time it's used

[shadow nacelle]

There all prefabs, and honestly do you want to look at the rest of my codes to see cause I genuinely don’t know 😭

[lean sail]

You should have some script that holds a reference to the prefab you want spawned, as your first step

[shadow nacelle]

I’m guessing it would be this? Thought it doesn’t have the items in there yet since I don’t know where exactly I would put them, but it seems like the correct place to put them

[lean sail]

read the bot command above on how to post code, photos of your screen really arent pretty to read

these are just strings still, if you reference a prefab, it would be of type GameObject or some monobehaviour

[shadow nacelle]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class InvManager : MonoBehaviour
{

public string Inventory;
public string[] possibleItems;
public int score;

// Start is called before the first frame update
void Start()
{
    Inventory = null;
}

// Update is called once per frame
void Update()
{
    
}

public void IncreaseScore(int add)
{
    score = score + add;
}

}

like that?

[lean sail]

re-read the command

[lean sail]

and also read this incase you missed it because i already commented on the code

[shadow nacelle]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class InvManager : MonoBehaviour
{

    public string Inventory;
    public string[] possibleItems;
    public int score;

    // Start is called before the first frame update
    void Start()
    {
        Inventory = null;
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    public void IncreaseScore(int add)
    {
        score = score + add;
    }
}

there we go t-t

[lean sail]

if you remove the initial space before the cs itll color code it too, but yea still same comment as above. this doesnt refer to any prefabs because its all just strings at the moment

[shadow nacelle]

okay so in the table script the invManager is a gameobject so maybe that?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using static UnityEditor.Progress;

public class Table : MonoBehaviour
{

    private string item;
    public GameObject invManager;
    public float cooldown = 3f;
    public bool onCooldown = false;
    public GameObject alert;
    public bool randomizeItem = true;
    public int addScore;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Player") && (invManager.GetComponent<InvManager>().Inventory == item))
        {
            onCooldown = true;
            alert.gameObject.SetActive(false);
            print("Item Delivered" + (invManager.GetComponent<InvManager>().Inventory));
            invManager.GetComponent<InvManager>().Inventory = null;
            invManager.GetComponent<InvManager>().IncreaseScore(addScore);
            CooldownRequest();
        }
    }

    IEnumerator CooldownRequest()
    {
        yield return new WaitForSeconds(cooldown);
        alert.gameObject.SetActive(false);
        if (randomizeItem)
        {
            int randomIndex = Random.Range(0, invManager.GetComponent<InvManager>().possibleItems.Length);
            item = invManager.GetComponent<InvManager>().possibleItems[randomIndex];
        }
        onCooldown = false;
    }

it's possible they want you to use Resources.Load or something, or possibly map the strings to prefabs with a switch statement or dictionary

kinda up to you I guess

[lean sail]

thats not a prefab, it is referencing an existing object in scene. Were you tasked with using this existing code and then spawning items? Im trying to see if your teacher intended for this to be done, because you could do what Praetor suggested but its just weird that these would be strings in the first place

[shadow nacelle]

yeah he basically made this code and made me think of a way to spawn the food item, and make it to where you can pick it up and see it on your screen and put it down at the designed table to gain points, though... I don't exactly get what he was going for at all

I'm aloud to fully change it but then I'm back at square one not knowing what to do

[lean sail]

if you dont mind me asking, is this highschool? Im just trying to get perspective on if the teacher really doesnt know what they're doing, or maybe i am missing some additional context.
It's really weird that items would directly check the player Inventory to then add itself, and the name Inventory is quite misleading since its really just a "HeldItemName" or whatever you'd like to call it. And then theres other issues with your Table code.
The first problem you'll need to solve is having a way to reference the food prefab. You want to put this on a script related to when the item should spawn.

[shadow nacelle]

yeah this is highschool

[leaden ice]

on a most basic level you can do something like:

if (item == "Hamburger") {
   Instantiate(hamburgerPrefab);
}```

that's a very simple way for a beginner to think about this.

[shadow nacelle]

and that would be for the 3 items I'm using?

[loud wharf]

If ur teacher is a pretty unreliable source, YouTube might be better. :p

I know a guide that shows the basics in around ten minutes or half hour ish.
It's just a flappy bird clone.

[shadow nacelle]

I would love the link ❤️

anything helps

[loud wharf]

And that tutorial already shows what you need to do the task.

[shadow nacelle]

ty ❤️

I will check it out

[lean sail]

you would do this for each item, to compare the name and then spawn the correct prefab. This script of yours is going to have to store a reference to all 3 prefabs.
Honestly I say you should do c# basics before unity, so you arent learning both c# and unity at the same time. Diving straight in unity is going to be rough

[leaden ice]

sure, make one for each item

[lean sail]

although i know in your case itll probably be tough since your class is using unity

[loud wharf]

I stopped using Unity.

[shadow nacelle]

yeah it's almost impossible to not do both for the class, but hopefully aftr I figure out this project were doing way easier stuff

[loud wharf]

Try learning C# in free time?

[shadow nacelle]

I plan on it! I just been busy with other things t-t

[loud wharf]

It would suck to have been learning how to make a game and have the entire experience be rendered pointless.
Then again, that's how I imagine school to be anyways.
