[knotty sun]

not at all

[fallow quartz]

it will change in every object with that SO

[knotty sun]

so you make SO instances

but if I understand you correctly what's wrong with simple POCO's consumed by your monobehaviours

so you dont want to share variables you want to share variable declarations

[fallow quartz]

tbf i dont understand this

[knotty sun]

well you say you want to share variables but you don't want one class changing the values used by another so what do you mean by sharing variables

[fallow quartz]

My problem is this:

How do I avoid duplicating variables without using inheritance

[simple egret]

You can use an interface

You won't be able to see your properties in the Inspector if you do so, though, on a field of the interface type

Inheritance works best here, especially when you don't know which of the 3 types you'll be getting at runtime

[woeful spire]

variables like health on objects would be great combined with inheritence. When it comes to actually taking damage you'd use an interface though.

A mix of both is usually ideal.

[stark sun]

I watched some tutorials to make my ragdoll character with inverse kinematic arms to grab objects. This is my code https://paste.ofcode.org/8LiM3cwQthT8X3GmiLXffD. I used trigger enter because using my hands as a collider broke some things.

I made debug.break(); when it enters trigger and checked the fixed joint I create with script and anchor looked normal.
So I cant understand why joints break.

[steady moat]

There is always the possibility to use composition, but I do not think you should. It increases the complexity considerably.

[fallow quartz]

interfaces dont solve the duplicate problem, and inheritance quickly becomes massive and hard to manage

[simple egret]

Then your problem cannot be solved without duplicating code

What is the actual issue here?

[steady moat]

You can also us helper function. By example, if the issue is duplicate code in the damage taking, you could create a DamageCalculator

[simple egret]

Sounds like an XY problem

[fallow quartz]

for example in the game i have a lot of abilities, each of them have their own variables but some of them are the same in other abilities and so

so its a complete mess of same variables between different abilities

or with the stats i have the same

[steady moat]

Why are they share though ?

[woeful spire]

sounds like duplicating code makes sense here though. If the abilities are different, they should have different metadata no?

[fallow quartz]

by share i mean for example fireball and spear both have "int range" variable

[steady moat]

Yeah, and you should have 2 classes with both different value.

Fireball

• int range

Fire Spear

• int range

[woeful spire]

Then in the ability you could use a "projectile" component if it should spawn something projectile-like?

[simple egret]

Can you have different abilities with the same underlying C# type? Like a HealthPotion and a HarmPotion both have an amount to add/subtract from the health. Which means both could be two instances of the same class (one with a negative value, one with a positive one)

Scriptable objects can do that

[fallow quartz]

yeah but writting int range in both of them is not good

[steady moat]

Just have a function:

• Set(string name, T value)
• Get(string name, T value)

[woeful spire]

duplication isn't inherently bad. In this case it hardly seems like duplication.

[simple egret]

The variables could be kept private/serialized, and to apply the ability the player would be injected into that

class HealAbility : IAbility
{
    [SerializeField] private float _healAmount;

    // Interface forces implementation of this method
    public void Apply(Player player) => player.Health += _healAmount;
}

[woeful spire]

if objects are going to share a lot of logic - then using inheritence makes sense. Depending on how much the fireball and spear are going to share it can make sense to create a "Projectile" class for them - using generalized terms like direction and speed.

If they are wildly different and only share one or two variables it might be easier to use interfaces.

[steady moat]

And if you do not know whatever the player has a health:

class HealAbility : IAbility
{
    [SerializeField] private float _healAmount;

    // Interface forces implementation of this method
    public void Apply(Player player) { 
      if(player.Has("health")) 
        player.Set("health", player.Get("health") + _healAmount); 
    }
}

[fallow quartz]

yeah theere is the issue. All abilities might share a few variables between them, so is not a lot of data but there are so many abilities with so many of them sharing a few variables between them

that using inheritance is really complex

[woeful spire]

not really. Just sharing the variables wouldn't be very complex? Where does the complexity arise?

Inheritance would be used to decrease complexity.

sharing general ideas between projectiles would make it easier to create another projectile later on no?

having the fireball - for example - use an interface specifically for abilities could be good. Have a general callback from the ability back to the user with a separate class to add knockback or heal the player would make sense here too.

[stark sun]

can someone take a look

[woeful spire]

What part of inheritence do you want to avoid exactly?

[fallow quartz]

making a big tree just for 1 variable shared on each pair of classes

btw is the setter useful? Cause if i want to change a variable i dont see any difference between changing directly the variable or creating a setter

[woeful spire]

if it's one variable, I think you can safely ignore inheritance. If it's shared behaviour between this variable, then inheritance can be convenient.

[steady moat]

Usually, in such case you want to use composition.
https://en.wikipedia.org/wiki/Composition_over_inheritance

[woeful spire]

they're nice if you want to do additional checks or run some method when setting the value.

If you just want to change the value then you wouldn't really need it.

[fallow quartz]

im doing it for the stats, but inside the stats i have the same problem cause there are variables

and btw composition gets me into a problem, i cant change the values of the variables inside without putting them into public

cause its not inheritance

[steady moat]

use [SerializeReference]

[steady moat]

It should not, give more context and example.

[fallow quartz]

not working

[woeful spire]

looks like the box becomes a child to my eyes - but I could be wrong. If that is the case, keep in mind that children follow their parent rotation and position in addition to physics. This can lead to strange behaviour. This box should not become a child when picked up. If that isn't the case then I don't know what the issue might be. Maybe try #⚛️┃physics ?

[woeful spire]

you'd need public for this.

[steady moat]

There is so many things that are wrong there.

Read on it before...

[woeful spire]

[SerializeReference] is for making something visible in the inspector.

[fallow quartz]

all my teachers say variables should be never public

[woeful spire]

what you're doing here is assuming it's public.

well...

[steady moat]

And they are right.

[fallow quartz]

i thought thats what serializefield do

[steady moat]

Its not.

[woeful spire]

I've used it wrong all along?

[steady moat]

And neither is SerializeField

[woeful spire]

oh my bad.

[knotty sun]

then your teachers are idiots and you can quote me

[stark sun]

I add a fixedjoint to a gameobject that is on my tip of each arms and then connect box to the joint. I also tried to do the parenting before but couldnt.

[sleek heath]

they are half right. They should be both public and private in certain circumstances

[steady moat]

It is for serializing reference as the same points out. You can show variable same if they are not serialized.

[steady moat]

In what situation it should be public ?

There is situation where it changes nothing, but none as far as I know that they should.

[woeful spire]

when you want to control a value from another script...?

[steady moat]

Maybe except for structure handling

[steady moat]

Us properties in those times.

[steady moat]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties

[knotty sun]

when you want to serialize it in a POCO

[woeful spire]

not really the case. You can use a property, but if you just want to change the value it becomes boilerplate no?

[steady moat]

You use [SerializeField]

[woeful spire]

You can use properties, but those properties would still be public right?

[steady moat]

It does not, C# has a really concept of properties.

[knotty sun]

that is a Unity attribute, not used by 3rd party serializers

[steady moat]

THey are not variable.

[steady moat]

In those case, you are right.

That being said, most serializier has their own properties.

[woeful spire]

I know ideally you want to isolate variables and use private - but wouldn't making them public be virtually the same as creating a property for them?

for this use case at least. Not in general of course.

[steady moat]

https://en.wikipedia.org/wiki/Encapsulation_(computer_programming)

It is a conceptual thing more than a pratical thing.

[stark sun]

why would I make something private? I can't think of any reason than not making inspector more crowded.

[fallow quartz]

wdym? any example

[woeful spire]

it has to do with good practice. Generally you only want other scripts to be able to access only and only what they need.

making things public exposes them, sometimes without reason, which is a big no-no.

To be honest though... when you're making your own game you can hold that shit together using duct tape, as long as it works. So you don't really have to stress that kind of stuff until you run into situations where you realize the actual issues it creates.

I think what's happening is that @steady moat is technically correct with everything they're saying - but you don't need to hold yourself to this standard when making stuff for fun. When coding production code and more advanced stuff you should hold yourself to these standards.

[steady moat]

public float Health {get;set}

instead of

public float Health

[fallow quartz]

Whats the difference

[steady moat]

It was in the context of professor saying that you should not use public variable.

[knotty sun]

and the difference is... none whatsoever except code bloat when you use properties

[woeful spire]

personally, the professor is wrong.

[knotty sun]

a property is a varaible

[fallow quartz]

what?

[fallow quartz]

only way right?

[steady moat]

Yes and no. They are functionally the same, however it handles you to protect what is exposed and what is not more easily. It states your intent.

[simple egret]

And if you ever need to do stuff when you get/set the value, you do it in one place (at the property), instead of at all the call sites

[woeful spire]

in this case, it's the fastest and easiest solution.

using properties would yield the same result in your case.

[simple egret]

C# conventions recommend you use properties to expose fields, but Unity pretty much doesn't care about properties lol

[steady moat]

First, using SerializeField and SerializeReference make no sense at all.

[knotty sun]

C# conventions were designed for app dev not for game dev

[woeful spire]

also, wouldn't this be different in Unity?
We can't serialize this property right?

[steady moat]

You can use [field: SerializeField] or use a backing field manually.

[fallow quartz]

Ok so in here, if i want to have the Add method inside Player instead of Stats, there is no way to change the values of my _stats in Player without declaring public every variable on Stats class?

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

[System.Serializable]
public class Stats
{
    [SerializeField] int _hp;
    [SerializeField] int _physicalDamage;
    [SerializeField] int _magicalDamage;
    [SerializeField] float _movementSpeed;
    [SerializeField] float _attackSpeed;
    [SerializeField] int _physicalDefense;
    [SerializeField] int _magicalDefense;
    [SerializeField] float _cooldownReduction;

    public int Hp => _hp;
    public int PhysicalDamage => _physicalDamage;
    public int MagicalDamage => _magicalDamage;
    public float MovementSpeed => _movementSpeed;
    public float AttackSpeed => _attackSpeed;
    public int PhysicalDefense => _physicalDefense;
    public int MagicalDefense => _magicalDefense;
    public float CooldownReduction => _cooldownReduction;

    //TODO [SerializeField] float _range;

    public Stats(int hp, int physicalDamage, int magicalDamage, float movementSpeed, float attackSpeed, int physicalDefense, int magicalDefense, float cooldownReduction)
    {
        _hp = hp;
        _physicalDamage = physicalDamage;
        _magicalDamage = magicalDamage;
        _movementSpeed = movementSpeed;
        _attackSpeed = attackSpeed;
        _physicalDefense = physicalDefense;
        _magicalDefense = magicalDefense;
        _cooldownReduction = cooldownReduction;
    }

    public void Add(Stats other)
    {
        _hp += other._hp;
        _physicalDamage += other._physicalDamage;
        _magicalDamage += other._magicalDamage;
        _movementSpeed += other._movementSpeed;
        _attackSpeed += other._attackSpeed;
        _physicalDefense += other._physicalDefense;
        _magicalDefense += other._magicalDefense;
        _cooldownReduction += other._cooldownReduction;
    }
}

[simple egret]

They could have at least used the conventions in place. But I guess other languages being supported in the past (which don't have properties) make interop more difficult

[fallow quartz]

thats true

[knotty sun]

bear in mind when Unity implemented C# they knew absolutely nothing about it

[woeful spire]

right, but the backing field in this case would be exactly the same as just exposing the variable as public in the beginning right?

[ivory smelt]

You mean differently that using "Class.Attribute = 1"?

[steady moat]

No. it would be private

[sleek heath]

is that why they had JavaScript and Boo?

[woeful spire]

in this case

we just want to access it.

[knotty sun]

yep, Unity is a MacOs app

[steady moat]

What case ?

[simple egret]

Sounds like the ones who designed the architecture of a database at work lol

[knotty sun]

tell me about it

[woeful spire]

the case we're discussing

having a public property and a private variable vs a public variable would yield the same results here right?

[steady moat]

public class Stats
{
  [SerializeField] private float _health;
  
  public float Health { get => _health; set => _health = value; }
}

[simple egret]

For example, tables that have a 1 to 1 relationship between each other have a third table in the middle which contains some data, as if it was a many-to-many relationship. So to join two tables you need more JOINs than usual, and conditions on the third table's join

[woeful spire]

would be virtually the same as

public class Stats
    {
        public float _health;
    }

in this case?

[steady moat]

In practice yes, but it that is not the point I'm making it here.

[knotty sun]

omg, that's bad. Have they never heard of DB Normalization?

[woeful spire]

I see, yeah okay. You're correct, but for helping @fallow quartz they can just do what I wrote and it'll be fine no?

[steady moat]

That was never the discussion. It was about whatever their professor are right to say that you should never use a public variable.

[simple egret]

Like if one day you'd like to have an event raised or a method called when the value changes, you'd only modify the property's setter and nowhere else:

public int Sample
{
    get => _sample;
    set
    {
        _sample = value;
        SampleChanged(); // new!
    }
}

And you'd keep your c.Sample = 42; unmodified everywhere else.

If you didn't have the property, you'd need to add c.SampleChanged() everywhere you set a new value to c.Sample

[fallow quartz]

well using serializefield makes sense so i can change the values through inspector

[woeful spire]

aha, my bad. I misunderstood the topic then :D

[steady moat]

Using both makes no sense. It shows that you do not know what SerializeReference means.

[ivory smelt]

how would u use that from another class? how would be the setter call?

[fallow quartz]

so for this how can I usea Add method from Player and be able to change the variables value?

[sleek heath]

this is exactly the case with WPF, where you need a OnPropertyChanged event handler

[steady moat]

It is a crucial part to make compositon base code. Which could be a way to architecture what you want.

[simple egret]

The setter is called automatically when you set a new value.

c.Sample = 42; // setter is called (= 'c.Sample.set(42)')
Debug.Log(c.Sample); // getter is called (= 'c.Sample.get()')

[sleek heath]

so it's basically an anonymous function?

[simple egret]

Yep properties are methods under the hood

The compiler makes the heavy lifting work

[sleek heath]

so in the IL, it will say "set()" and "get()"

[simple egret]

Yup

[ivory smelt]

but u must have a private value version of the attribute to use this or where else does _sample come from?

[simple egret]

Yeah I omitted it in my example, but you need a field to back the property up

Unless you use an auto-property ({ get; set; }) in which the compiler creates that field for you

Next C# version will allow you to refer to the field directly, eliminating the need for a field when you have code in the accessors:

public string Name
{
    get => field; // 'field' now a keyword referring to the compiler-generated field
    set => SetField(ref _field, value);
}

For my WPF MVVM lovers

[sleek heath]

C#14?

[simple egret]

I stopped counting but it should be in .NET 9 which releases next week-ish (?)

[sleek heath]

it already released

a month ago

[simple egret]

hmmm I'm late then

Stuck with Framework 4.7.2 at work 💀

[knotty sun]

what a waste of space. even more bloat for a simple 'public string Name;'

[sleek heath]

well, we are stuck with Framework 4.7.1 until Unity 7

[simple egret]

This notifies the UI the value changed so it redraws. Nowadays a source generator can hide that away from you

[fallow quartz]

yeah but u get problems like the one from the Add method

[knotty sun]

but it hides nothing from IL which is what matters

[fallow quartz]

that force u to make variable public

[sleek heath]

you need to notify XAML with the OnPropertyChanged(nameof(Name));

[ivory smelt]

So, correct me if im wrong or missing something, but would this be the correct cheatsheet?

    private GameObject _attributeA; //full private

    public GameObject _attributeB { get; private set; } //readonly

    [SerializeField] private GameObject _attributeC;    //inspector serializable readonly
    public GameObject AttributeC => _attributeC;

    [field: SerializeField] public GameObject _attributeD { get; private set; } //inspector serializable readonly BEST PRACTICE

    public GameObject AttributeE { get; set; }  //full public

    private int _attributeF;    //full public BEST PRACTICE
    public int AttributeF { get => _attributeF; set { _attributeF = value; Example(); } }

[steady moat]

public class StatisticRepository 
{
  [SerializeReference] private List<Statistic> statistics;

  public void Combine(StatisticRepository other) {...}
}

(If you have different type of statistics, other wise you can use [SerializeField])

[simple egret]

A: Field, private
B: Property, read-only (outside of declaring type)
C1: Field, private (+ Unity recognizes the attribute so it's displayed in the Inspector - not base C#)
C2: Property, read-only
D: Property, read-only (outside of declaring type + marks the compiler-generated field with the attribute so it's displayed in the Inspector)
E: Property, public, read-write
F1: Field, private (backing field of F2)
F2: Property, public, with custom accessor logic

[thick terrace]

and with a bit of extra code you can enable init properties in Unity for some extra fun 😀

[steady moat]

_XXX is used for private field usually.
[field: SerializeField] is not the best practice nor a bad one.

[fallow quartz]

i just change my code on stats to use field: SerializeField and is not taking properly the values, everything is on 0

[ivory smelt]

alright I got it, so this is the go-to or there is something I should change?

[ivory smelt]

so is the one before that the right one regardless being longer and not being able to include custom logic?

[thick terrace]

you mean the old values disappear? even if the name appears the same in the editor, the name of the backing field unity is serializing for an auto-property is different to the old field so you'll need [FormerlySerializedAs] to make it upgrade smoothyl

[steady moat]

Not sure what you mean. There is no "Right One".

[simple egret]

Just need to adjust your terminology!
When it has accessors (get, set), it's a property.
When it doesn't, it's a field.
Attributes are the things you put in square brackets []. SerializeField is an attribute for example.

[ivory smelt]

Each one is useful for different situations, but there is at least one that is overall better, like public GameObject AttributeE { get; set; } over public GameObject AttributeE;

[ivory smelt]

In spanish we call fields "atributos" so I automatically call those attributes, my bad

[steady moat]

I would say so. However, it is debatable.

[simple egret]

Yeah in data modelling graphs these are also called attributes if I remember correctly

[thick terrace]

not necessarily, everything has a use! for example in that example you can't take the value of the property by reference, which could be useful in some niche cases

[ivory smelt]

wdym? you cannot acces it from Class.AttributeE?

[steady moat]

A structure by example.

public MyStruct PropertyA {get;set;} will return a copy of the structure.

[thick terrace]

you can't do ref AttributeE for a method that takes a ref parameter, if AttributeE is a property

[steady moat]

Hence, you will not be able to modify it directly, you will need to set it back after you are done.

[fallow quartz]

every value, the screen, the debug log and the values after scene changes

[ivory smelt]

So one returns itself and the other returns a copy of itself essentialy?

[steady moat]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/reference-types
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/value-types

[thick terrace]

kinda but to be pedantic fields don't "return" anything because they're not methods, they ARE the data

[ivory smelt]

Yeah a reference is a "path" to the data, while a property is a copy of the data itself

But what im not getting is in which cases a field is initialized as one or another

[steady moat]

no.

Property is something else. You have Reference Type and Value Type. If you return a value type it is a copy of the data, if you return a reference type it is a copy of the pointer towards the data.

If you use a property you "return" something. If you use a public field you access directly the data.

[fallow quartz]

If a gameobject doesnt execute again Start when using dontdestroyonload, why my stats stay fine if I do it like in the image but reset if I declare it on the start? And whats the difference?

[ivory smelt]

like here im getting it but where does the difference begin? declaring the variables?

Dude i know how to program and suddenly I feel stupid asf its like i have forgot the basics lmao

[steady moat]

The difference is in the struct. If it is a class it is a reference type.

And the behavior differ

[ivory smelt]

So it depends of the object type?

[steady moat]

Yes

If you were to replace struct by class, you would not get the same result.

[ivory smelt]

I understood here that it was dependant of how u declared the field

while you were talking about class types

[thick terrace]

yes, reference and value types are a different topic to what we were talking about

[ivory smelt]

damn XD

[steady moat]

One of those niche case is when you deal with value type

[ivory smelt]

alr alr

[ivory smelt]

so overall, outside of structs, enums and allat, everything else (classes, interfaces...) lets say the common stuff, should allow this without trouble

Thanks yall @steady moat@simple egret@thick terrace, I really appreciate your help! ^^

[main shuttle]

Why are you yelling?

[knotty sun]

and that is our problem why?

[worn brook]

No

Sorry

I just wanted to share my suffering with someone

[rugged fulcrum]

Does anyone know if its possible to resize a vertex buffer? I'm creating an empty max size vertex buffer to pass to a compute shader, but after i've generated these I'm almost always left with a lot of unused space at the end, any way to trim this out without copying a subset into another buffer?

[vocal night]

Are state machines common for animations in 3D games?

[leaden solstice]

If you mean Mecanim yes? That’s the standard Unity workflow

[cosmic rain]

Doesn't seem like there's a way to do that aside from copying. Perhaps you should estimate the number of elements better when creating the buffer.

[vocal night]

I don't know what I mean anymore omg. I was watching this tutorial to recreate genshin movement cause I thought I could build my knowledge from there but he's doing something I've never seen before

he creates these statemachine scripts and every single motion has it's own state machine which makes no sense to me cause normally, I thought we controlled them with variables in the animator tab

[rugged fulcrum]

Then pooling the vertices seems like the way to go, thanks for the response though.

[vocal night]

I just want to know how to properly animate a 3d character tbh

and adding complex motions to those characters

[leaden solstice]

Statemachine behaviors are something you can attach to your states, generally useful when you need event when entering state etc. Animator params control transitions and some state properties like speed.

Read docs and try it out

[vocal night]

where and how?

[leaden solstice]

You didn’t even use a second to search?

Good luck

[vocal night]

I did but I understand nothing that's why I'm here

[cosmic rain]

Then start simpler. Research the things that you don't understand. Or at least explain what it is that you don't understand so that we can direct you to the proper learning resources

[vocal night]

any good resource on humanoid character animation would be lovely

going simple from like walk and run to actions like swim, point and all

[cosmic rain]

Well, that's a pretty simple thing to setup with the animator, so either look at the animator manual or search for some tutorials on YouTube or !learn

Hi so after updating my unity version, when I make new scripts, for a short time my console gets spammed with this message. Doesn't seem to be affecting anything in the game and it stops shortly after the script is created, give or take 3 seconds. I was wondering what this means and how to fix it!

[tired raptor]

How do I fix this error?

[ocean hollow]

looks like a synchronization delay between os time scale and given time scale. try deleting your library folder and seeing if that helps

[ocean hollow]

what is that script attached to

[tired raptor]

Its just the defualt global light 2
Im creating a 2d multiplayer game with FOW and imported this data

[tired raptor]

am I missing a setting to enable?

[ocean hollow]

sorry im not very familiar with 2d so im not sure

but this question would be more suited for #💻┃unity-talk

try asking there

[wintry stone]

I'm trying to make a healing beam similar to mercy from Overwatch does anyone know how to make the line renderer curve when the direction of the healing staff is facing a different direction than the target? Or if their is a better way to make this than a line renderer?

[rigid island]

probably some type of shader? maybe a spline mesh on it w shader ?

more of a #✨┃vfx-and-particles / #archived-shaders question i think

[wintry stone]

ok I didn't know if their was any way to do it with code with the line renderers points and just wanted to check

[rigid island]

I would honestly use a spline type deal with a shader, or the shader itself can just create that curve effect instead of bending the mesh

[rigid island]

with code you would probably need to use bezier curves and line renderer or something
btw found these https://youtu.be/R0A0rWljTm4
https://youtu.be/NMAAeGiEHwk might help out if you go in the VFX route

[calm echo]

Use a Bézier curve

[wintry stone]

yeah the bezier curve works thanks!

Has anyone here integrated the SteamUtils API in their code?

Kind of confused -- I'm not sure how to A) check if the user has pressed the "submit" button and

B) How can we get the entered text?

        if (SteamManager.Initialized)
        {
            Debug.Log("IS RUNNING ON STEAM DECK");

            bool isShowing = SteamUtils.ShowGamepadTextInput(
                EGamepadTextInputMode.k_EGamepadTextInputModeNormal,
                EGamepadTextInputLineMode.k_EGamepadTextInputLineModeSingleLine,

                StartCoroutine(CheckForSubmit());
            }
        }
        else

        }
    }

    private IEnumerator CheckForSubmit()
    {
        // Wait until the overlay (virtual keyboard) is closed
        while (SteamUtils.IsOverlayEnabled())
        {
            yield return null;
        }

        // After the overlay is closed, retrieve the text
        string enteredText;
        uint bufferSize = (uint)maxCharLimit;

        }
    }

}

It looks like the "enteredText" is empty

I basically just want to get whatever text is inside the box that pops up -- whether the user modified it or not through the virtual keyboard -- and make that the "enteredText"

[leaden solstice]

I believe you should call that method only within GamepadTextInputDismissed_t callback.

The struct also contains if user submitted or not

how does one un-unpack a prefab

[soft shard]

If a prefab is unpacked in a scene, you cant re-pack it unless you Ctrl + Z and undo the operation, otherwise it would be easier to just drag another prefab into the scene again, unless your wanting to make a prefab variant

[clever leaf]

hey, a question: does unity support auto-tiling at runtime, or would I have to implement that system myself?

[sudden lantern]

Hi. I get an error that says "Layer index out of bounds" when I'm trying to log the layer name. What can cause this?

var context = ActorContext.Context;
Vector3 origin = context.transform.position;
Vector3 direction = -context.transform.up;

Ray ray = new Ray(origin, direction);
Document doc = SonicGameDocument.GetDocument("Sonic");
ParameterGroup group = doc.GetGroup(SonicGameDocument.CastGroup);
float castDistance = group.GetParameter<float>(Cast_Distance);
LayerMask mask = group.GetParameter<LayerMask>(Cast_RailMask);

Debug.Log(LayerMask.LayerToName(mask));

[knotty sun]

LayerToName takes a Layer ID not a LayerMask

[past raven]

why do my sprites get fucked up when i unpack

i fucking hate unity

[cosmic rain]

Don't use it.

[past raven]

it's too late i already invested 10 years into this bullshit

[knotty sun]

10 years and you still dont know how to use it properly, shame on you

[past raven]

why is it doing this shit to my character

[cosmic rain]

Doing what? How is supposed to look(and where)?

[past raven]

just look at it

the body is all fucked up

[cosmic rain]

Well, why would it not be? What is there to make it look correctly?

[past raven]

ok you're trolling

[cosmic rain]

No, I'm trying to drag more details out of you. Otherwise it's impossible to help you.

[past raven]

the body is to the left of the rest of the character

body and arms

[cosmic rain]

Yes, that much I figured out. I'm asking why it shouldn't be? What are you using to make it look orderly as you expect?

[past raven]

it looks fine before i press play

scene view

then it gets all fucked up after i play

[cosmic rain]

Take a screenshot

[cosmic rain]

I really hate making assumptions, but I guess you're using bone animations or something. The fact that it breaks at runtime means that there is an issue with your rig setup or animations.

[past raven]

ah my animation

[knotty sun]

You also have a null ref exception in your console which may have something to do with it

[fallow quartz]

If I have this inheritance hierarchy and there is a same variable on those 2 classes, is there any way to avoid duplication?

[cosmic rain]

Pull it out into a base class.

Make these 2 child classes inherit from an intermediate class that has the field.

[fallow quartz]

but the variables in the parents of this 2 classes are not the same

im going to make 1 full class just for 1 variable?

imagine this for each variable thats shared

would be crazy

[cosmic rain]

Not advisable. This might point that there is an issue with your design. Maybe you should be using composition more and inheritance less.

If you give an actual real life example of your issue, it might be easier to provide a suggestion.

[fallow quartz]

is there more "tools" apart from inheritance and compositions for this type of stuff?

so how do I get a good design

[cosmic rain]

There are all kinds of design patterns, but it's hard to say what would fit here without knowing the context.

[clever leaf]

bump

[vestal arch]

tiling what exactly, a background or actual tiles?

[clever leaf]

i wanted to make a destructible 2d environment

the idea is that you mine tiles for gold

and I was wondering if auto-tile at runtime is supported

[vestal arch]

yeah i don't think something like that would be implemented

too many specific details to make a general solution

[clever leaf]

ffs

[vestal arch]

not too hard to make though

[clever leaf]

so I won't escape having to make it

wonderful

thank you

[vestal arch]

yeah, specific systems are like that

[clever leaf]

is it so specific though?

you already can define rules for tiles

in editor, at least

if they were able to make it work in the editor it seems weird it doesn't at runtime

I have no real experience using tiles so I might just be outright wrong though

[vestal arch]

• what range? (camera edge or distance from player)
• what tileset? (maybe weighted, maybe depends on some different variable)
• what is replaceable?

your answers to these create a specific system

[clever leaf]

1. aren't tiles just placed based on a grid? distance/camera has nothing to do here
2. don't exactly know what you mean here
3. you can replace any tile at runtime, so I don't see how that matters

[vestal arch]

aren't rule tiles just.. tiles with specific behavior
they don't create new tiles, they just modify existing ones

[vestal arch]

1. conceptually, yes, but you can't generate infinitely. you have to decide when to start generating.
2. what tile(s) should be used when generating new areas? how are they weighted? for example, if there's a concept of depth, then maybe that affects what tiles spawn, or the weight in which different kinds are chosen
3. i mean, within the system. what tile should be replaced? you shouldn't generate stuff over existing tiles, or that would just close up anything you destroy

[charred swift]

Hi,
Is it possible to make a specific camera not render the environmental lighting?

[clever leaf]

I'm not generating anything at the moment, for now I wanted to just remove a tile and see if surrounding ones "adapt" at runtime, nothing fancy...

nevermind

[vestal arch]

oh, i have severely misunderstood what you meant by "auto-tile" lmao

for that yeah pretty sure rule tiles work at runtime

[clever leaf]

great, that's what I wanted to know, thanks

[ivory smelt]

In Unity, is there a way to automate the declaration of properties by composition?
For example. If I put a tag [RequireComponent(typeof(DoorBehaviour))], a DoorBehaviour _doorBehaviour property is automatically created, and also _doorBehaviour= GetComponent<DoorBehaviour>(); is added to the existing Awake() or a new generatedAwake if not implemented yet?

[warm cosmos]

you can require components on gameobjects?

that's very cool actually

[ivory smelt]

on classes but yeah

it automatically puts the desired behaviour into the gameObject but u must do it from a script with class

[fallow quartz]

Can someone help me with the last question in that thread pls? Idk why when initializing the stats on start they are at 0 all the time but if I do It outside or on awake it works properly

[knotty sun]

does the object implement the singleton pattern?

[fallow quartz]

no, its just a sphere with the player script inside

[leaden ice]

So... Is there another copy in the scene you're loading?

[fallow quartz]

of the sphere? No, its the only one

[knotty sun]

then when the scene reloads a new version will be created and Start will run on that

[leaden ice]

But you're reloading the same scene, no?

[fallow quartz]

another one

[fallow quartz]

im not reloading, its going into a new scene

[leaden ice]

Which scene are you loading and what's in the new scene

[fallow quartz]

im in a UI menu, I choose the race, class and weapon, then i confirm with the button, goes into another scene and the sphere appears on top of a cube with that script

[knotty sun]

Start will not run on a DDOL object after it is first created, so no it will not run again

[fallow quartz]

so why is this happening then?

[knotty sun]

almost certainly you are misinterpreting what you are seeing. Debug the Start method if you think it's running twice

[fallow quartz]

I made a debug log and the stats are at 0 even in the scene before, so i dont think the problem is DDOL

Debug.Log(playerInstance.GetComponent<Player>().Race.Stats.Hp);
Debug.Log(playerInstance.GetComponent<Player>().Race.Stats.PhysicalDamage);

I added this 2 lines just right under BuildPlayer has been executed

and they are on 0 but the object has the stats on the next scene

[past raven]

i have a sprite sheet for animation

but i cant drag it into the scene

i can only drag it under another object

and it doesnt show it

nvm

solved it

[fallow quartz]

@knotty sun @leaden ice

public void ConfirmSelection()
    {
        GameObject playerInstance = Instantiate(playerPrefab);

        CharacterRaceTemplate selectedRace = GetSelectedRace();
        CharacterClassTemplate selectedClass = GetSelectedClass();
        WeaponTemplate selectedWeapon = GetSelectedWeapon();
        ArmourTemplate selectedArmour = GetSelectedArmour();
        TrinketTemplate selectedTrinket = GetSelectedTrinket();

        Player playerScript = playerInstance.GetComponent<Player>();

        if (playerScript != null)
        {
            playerScript.BuildPlayer(selectedRace, selectedClass, selectedWeapon, selectedArmour, selectedTrinket, "YOU YOU");

            Debug.Log(selectedRace.Stats.Hp);
            Debug.Log(selectedRace.Stats.PhysicalDamage);

            Debug.Log(playerInstance.GetComponent<Player>().Stats.Hp);
            Debug.Log(playerInstance.GetComponent<Player>().Stats.PhysicalDamage);

        }

        DontDestroyOnLoad(playerInstance);

        //SceneManager.LoadScene("Test");

        //Debug.Log("Character with: " + selectedRace + selectedClass + selectedWeapon + selectedArmour + selectedTrinket);
    }```

the issue could be that when i instantiate the object start is not running right there?

[knotty sun]

Start will run if the Object and the script are active/enabled AFTER all of that code is finished

[fallow quartz]

and why is not running as soon as is instantiated?

[knotty sun]

because your code is still running. Only Awake is guaranteed to run when Instantiate is called

[fallow quartz]

yeah then thats why it works in Awake and not Start

If I do it like this, when are stats initializing? Before Awake?

public abstract class Entity : MonoBehaviour
{
    [SerializeField] protected string _name;

    [SerializeField] protected Stats _stats = new Stats(0, 0, 0, 0f, 0f, 0, 0, 0f);

    protected virtual void Start()
    {

    }
    protected virtual void Update()
    {

    }
}```

[upper pilot]

Why is https://docs.unity3d.com/2022.3/Documentation/Manual/UIE-Pointer-Events.html
Missing IPointerExitHandler?
Which pointer events do I need in order to replicate button hover states to change color?(I need this specifically to change color of text based on a pointer state)

[knotty sun]

Unusual construction. Obviously as an abstract class that is never initialized

[fallow quartz]

but imagine I put values and is not 0, 0, 0, 0

like when is that being initialized? cause in unity u can see the values

[knotty sun]

if you are talking about a class inheriting from that then the serialized values are set before Awake

[fallow quartz]

and in this class in particular its also before awake?

[knotty sun]

no, as I said, it's an abstract class so can never be instanced

[fallow quartz]

well imagine is not abstract

public class Player: MonoBehaviour
{
    [SerializeField] protected string _name;

    [SerializeField] protected Stats _stats = new Stats(0, 0, 0, 0f, 0f, 0, 0, 0f);

    protected virtual void Start()
    {

    }
    protected virtual void Update()
    {

    }
}```

[mellow sigil]

https://docs.unity3d.com/2022.3/Documentation/ScriptReference/UIElements.PointerLeaveEvent.html
https://docs.unity3d.com/2022.3/Documentation/ScriptReference/UIElements.PointerOutEvent.html

[fallow quartz]

its just to know the theory of how it works

[knotty sun]

then what I said above is true, deserialization takes place after instancing and before Awake

[fallow quartz]

Okay, and for this particular case where i want a gameobject to get the stats from templates (SO), is it better to move the initialization of stats from entity to Awake or where it is or leave them on the start and just create a gameobject right instant before the method executes? (which is really annoying, I thought instantiate would instantly activate start and trigger before the whole method finishes)

[knotty sun]

best, if you want instant access to the variables is to set them in Awake, that way you will know they will always be avaialble

[fallow quartz]

Perfect, thanks so much ❤️

[ivory smelt]

Hello, does anybody know if there any way to avoid having to move every reference in the inspector after you change variable names? Its really annoying when you have a lot of references or even lists. I also find quite unpleasant doing it by code through FindByName.

[rotund finch]

Hello, having some issues with event triggers not triggering

[fallow quartz]

When you design a inheritance hierarchy is it more efficient to start building from the childs onto the fathers or from the base class into the childs?

[hybrid ingot]

Hey guys any ideas why this FPS displacement script works on editor but not on build?

{
    public TMP_Text fpsDisplay; // Reference to a UI Text component to display FPS

    private float deltaTime = 0.0f;

    void Update()
    {
        deltaTime += (Time.deltaTime - deltaTime) * 0.1f;
        float fps = 1.0f / deltaTime;

        // Update the Text component with the FPS value, rounded to whole number
        fpsDisplay.text = "Current FPS: " + Mathf.Ceil(fps).ToString() ;
    }
}```

[rigid island]

in what way is not working?

[thick terrace]

FormerlySerializedAs?

[ivory smelt]

how does that work

[thick terrace]

when you rename a field put that attribute on it to tell the serializer the old name, it'll keep the old value and save it under the new name the next time the asset is saved

so you can remove the attribute later if you're sure all the assets have been resaved

[ivory smelt]

Ill check it out, thanks brother!

[hybrid ingot]

well when I play the game in the editor I see it updating the text according to the fps, but when I build the game it gets a static number, meaning that its not updating the text tho for some reason, asked chatgpt and it said it might be due to textmeshpro, but also no alternatives were said to solve it.

[rigid island]

that is expected, gpt is text conversation machine, its not a thinking machine
anyway make a dev build and check for any null references on screen or in the PlayerLog file, also double check you are exporting the correct scene

[hybrid ingot]

loved the gpt tea! Well will try that thank you 🙂

[rotund finch]

I have this prefab which I instantiate at a certain point in my game, and to which I attach through code an event trigger. Still through code I add a method as a listener.

This is the code that adds the method as a listener:

[HideInInspector] public UnityEvent onClick = new UnityEvent();

    private EventTrigger eventTrigger;

    private void Start(){
        eventTrigger = GetComponent<EventTrigger>();
        EventTrigger.Entry clickEvent = new EventTrigger.Entry()
        {
            eventID = EventTriggerType.PointerDown
        };

        clickEvent.callback.AddListener(OnClick);

        eventTrigger.triggers.Add(clickEvent);
    }

    private void OnClick(BaseEventData shit){
        Debug.Log("AAAAA");
        onClick?.Invoke(); 
    }

The event system is in the hierarchy, and the object presents nothing but an image component and the component itself

[leaden ice]

Why make a UnityEvent just to hide it in the inspector and use an event trigger instead?

[rotund finch]

as I don't wanna go through the hassle of handling a collider in there

[leaden ice]

Collider?

What does that have to do with the question

[rotund finch]

ok, maybe I have explained my self poorly

[leaden ice]

If it's not a UI element it needs a collider for On click to work

As well as a physics raycaster on your camera

If it's UI it needs to be on a canvas and have a Graphic component and you need a graphic raycaster on the canvas

But this business with the extra UnityEvent is definitely not necessary in any case, it's a bit wasteful

You can also just implement IPointerClickHandler directly and avoid the event trigger entirely

[rotund finch]

How do I make it so that the press of a button, through a second camera, with its feed displayed on an object through a render texture, is registered?

when I say button I mean an UI element

in world space

[leaden ice]

You'd need to make a custom raycaster that translates the click from the Raw image component to another event system Raycast in world space for that to work

[rotund finch]

I see

[leaden ice]

Assuming you're using RawImage

If it's a mesh displaying the RT you need a physics Raycast first

[rotund finch]

I'm doing this, so yeah

so i first translate the mouse movement from the main camera's space to the second one's and then what?

[leaden ice]

No first you do a physics Raycast to the mesh. Use the texture coordinate from the hit to figure out where on the second camera to fire a second Raycast from your Graphic Raycaster on that camera from

Ideally you'd do this

In a custom event system raycaster

Because then it will work with Event Trigger

[fallow quartz]

If i need to make a CD for an ability is better to use coroutines or just use a variable with time.deltatime?

whats more efficient

[rotund finch]

ok, thanks

[gray mural]

It will always be a little bit efficient to check a boolean in Update rather than add an additional Coroutine, which is called at the end of the Update method. However, the difference is really small, and, in my opinion, it's more readable for you to use a Coroutine

[leaden ice]

Efficiency should not be your primary concern at this point.

Readability and code architecture should be

[rustic ember]

Hi! I have a question regarding performance. Is there a difference in performance in these two lines, and if so, why? They both give the same result, but if one is faster I will use that.

int x = a+b*c-b;``` vs
```cs
int x = a+(c-1)*b```

[leaden ice]

It's the same number of operations

[thick terrace]

and even if it wasn't this would be the very very least of your performance concerns in a unity game haha

[leaden ice]

Indeed

Assuming these are all ints at least

Also assuming none of them are properties

If b is a property it would be different

Or function call

[steady moat]

Personally, I do not really like the usage of Coroutine in that context. I tends to use a startedAt value.

Something like:

private float startedAt;
public void Use()
{
  startedAt = Time.time;
}

public float RemainingCooldown() => Cooldown - (Time.time - startedAt)

[fallow quartz]

shouldnt i use time.deltatime?

i thought it was better

[rustic ember]

What is a "property" in this context?

[steady moat]

Why ? If you do not need to count the time, do not.

Do you count every minute you are alive to keep track of how much time you have been alive ?

[rigid island]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties

[rustic ember]

Thanks. So getting a property of a different class is slower than getting a property from the same class?

Or is it always slower getting a property of a class than getting a variable within the method?

[fallow quartz]

no

[rigid island]

properties work more like methods. fields are always "faster"

fields are generally direct access to memory, method has to create a stack allocation

[rustic ember]

Still not 100% sure what the difference between fields and properties are 🤔

[rigid island]

best to look them up. Field is generally when you create the variable like
private int myField

property always have accessor public int MyProperty {get; set;} // <-accessor

[rustic ember]

Ah, okay! Thank you for explaining it 😊

[rigid island]

when you get value run this function
when you set run this function
and you can specify what to do on each one with a function

[tawny lintel]

Hi, is there any way to increase the NavMeshAgents priority level above 99? I need it for making an RTS with hundreds or thousands of units on screen. I want to use it to make units not overlap in various situations. 100 positions is also very bizarre, it's and Integer, so why only 100 values?

I have made various systems such as moving in formations or keeping group shapes, moving around corners with a random distance for big groups, etc...

But it's still not enough. For example a group of units attacking a single unit ends up having all units overlap pretty hard. If units that are closer to the target had a higher priority, it would reduce the overlap significantly. But I need to have 100.000 to 1.000.000 priority levels to achieve this.

Thanks for your time!

[knotty sun]

dont cross post

[tawny lintel]

Ok sry I wasnt sure which of the two channels to post it to so I did both just in case

[leaden ice]

No. Calling a property is the same as calling a method/function, so fewer of them is better

is there any reasonable way to search for text across all of the user-made scripts in my project? it would be in any .cs files in Assets/_Project. I want to search for the number "204" as i want to swap it out to a variable rather than hard-coded number

[rustic ember]

Hi! I am overwriting a texture with Texture2D.SetPixel(), and then calling Texture2D.Apply(). After running the script, it shows the old texture when I open the png file in another program. How do I make it show the new texture instead?

[rapid glen]

Are you saving the texture?

byte[] pngData = texture.EncodeToPNG();
if (pngData != null)
{
    File.WriteAllBytes("path/to/your/texture.png", pngData);
}```

[rustic ember]

No, I didn't know I had to. Thank you 🙏 Is there a way to get the path from the Texture2D? Something like texture.path?

[rapid glen]

you cant get it directly from the texture2d that i know of.

if you are getting the original image through code then maybe you could store that path?

[rapid glen]

i pasted exactly what you asked in to GPT and it told me that lol

[rustic ember]

Alright, thank you

[rustic ember]

I'm not really confident that GPT knows what's right. I could be wrong 🤷‍♂️

[spare dome]

gpt only knows what the internet knows

so it most likely took that from stackoverflow or some other site

[rustic ember]

"path/to/your/texture.png"? What is the origin folder?

Do I have to right "C:/...", or is it already in the folder that the script is in? Or the asset folder?

[rapid glen]

i believe it's the exact path with C:/... though i think there are variables to get certain paths

like filePath = Application.persistentDataPath + Path.AltDirectorySeparatorChar + "data.json"

which will be in your Appdata LocalLow

[rapid glen]

generally with "simpler" things gpt is solid. especially now with 4o/4o mini. definitely good to double check it's work though if you're not sure, and make sure to understand all the code ofc

[knotty sun]

Generally you would use Path.Combine to create path strings

[rapid glen]

oh so i dont need that separator char? like filePath = Path.Combine(Application.persistentDataPath, "data.json") ?

[knotty sun]

nope

[rapid glen]

ah

nope to the first part or second? xP

[knotty sun]

nope you dont need the seperator

[rapid glen]

sick. that excerpt would be a proper replacement then?

[knotty sun]

yes

[rapid glen]

sweet. ill keep that in mind in the future

Does anyone know a way to see all forces applied to a specific rigidbody?

I am having troubles with a CarController where I let go of gas pedal and car continues to accelerate for an amount of time. time it accelerates for scales with the speed of the vehicle when i let go of gas pedal. i want to ensure there is not some random script somewhere affecting that rigidbody.

In my Update() i have throttleInput = Input.GetKey(KeyCode.W) ? 1 : 0;

and in FixedUpdate() i have

{
    rlWheelCollider.motorTorque = 2000;
    rrWheelCollider.motorTorque = 2000;
} else {
    rlWheelCollider.motorTorque = 0;
    rrWheelCollider.motorTorque = 0;
}```

I have made **certain** that `throttleInput` and `motorTorque`  work exactly as they should by using a Debug.Log. I have disabled everything else in this script, and know for a fact that the other two scripts on the vehicle do not deal with movement in any way. vehicle has a custom mesh collider and rigid body, children wheels have the wheel colliders.

[naive swallow]

Does anyone know a way to see all forces applied to a specific rigidbody?

rigidbody.velocity. That's the result of all forces on the object.

[rapid glen]

I mean to see if there is some random script somewhere applying forces. I don't think rb.velocity is what I'm looking for because i can see that the vehicle is moving

[spare dome]

I believe its called Rigidbody.linearVelocity now

[rapid glen]

I'm moreso asking about finding sources of velocity, not seeing the actual velocity of the vehicle. I have an onscreen Km/h for that 🙂

[spare dome]

sources of velocity, elaborate.

[rapid glen]

I have looked at all references to the gameobject that has the rigidbody and none of the scripts on those objects add forces

[spare dome]

do you have any physics materials on your car, do you have friction on your car?

do you have raycast suspension?

[rapid glen]

Well you see the code snippet I offered above, so you would expect that when I let go of W and motor torque is set to 0 (i know for certain it goes to 0), that the vehicle would decelerate or at worse stay the same speed, however it continues to accelerate

i only had the keypress and the motor torque code enabled on the script. anything else would come from the wheel collider or rigidbody

oh whhops i didn't open the dropdowns

@spare dome do any of these values jump out as wrong?

[spare dome]

does it keep accelerating forever after input or accelerates longer after you stopped the input then stops after a while?

[rapid glen]

stops after a while. the faster i am going when i let go of W the longer it will take to stop accelerating

[spare dome]

does it stop accelerating after a second or two then starts to slow down?

[rapid glen]

yeah

[lean sail]

Should be able to right click the rigidbody or the gameobject and click find all references (or whatever the option is called)

[rapid glen]

if im going like 15kph and let go it gets to like 25, but if im at 100kph it will go to like 200 or so

even though motor torque is def set to 0 on the wheels

[rapid glen]

did try that, looked at all scripts on all game objects that referenced it. did not find anything

and yes it slows down normally once it stops accelerating

[spare dome]

try making the rigidbody drag higher

just a wild guess

[rapid glen]

ok what you think?

like 5?

[spare dome]

try 1 - 5 to see what works if at all

[rapid glen]

setting drag to 1 using 5000 motor torque on back wheels lets me get to 19kph 😛 doesnt fix issue though :/ i let go at 5kph and still goes to 19

drag at .1 still same accel issue but i can go higher speed 😦

[chrome trail]

I'm trying to create a display for a sort of movement area for a character (That is the maximum distance a character can move in one turn) and I want to omit the vertices outlined in green from the final mesh. While I know how to find what vertices should be omitted, I don't know how I would go about drawing the triangles for these meshes let alone in a way that only omits the areas outlined in green. Any ideas?

[cosmic rain]

One thing that seems suspicious is that the rb is kinematic? I don't think it's supposed to be kinematic for a setup with wheel colliders. Or are you changing that via code?

[cosmic rain]

What is the purpose here? To prevent these vertices from being rendered?

[rapid glen]

yeah it's kinematic until the car is finished being set up

[chrome trail]

More to prevent that entire area of the decal (that's what I'm using to display the area) from rendering. I know how to find the vertices I need to exclude, but I don't know how to draw the mesh with the remaining vertices so that the area displays properly

[pale shoal]

is there a way to put 3d models in while the unity game is running i think we can use addressables no?

[cosmic rain]

Okay.
I think wheel colliders have something like inertia, where even if the motor torque is set to 0, they would keep on applying forces depending on their rotation speed and other parameters. I think wheel damping is meant to control that. Can you try setting a higher value for wheel damping?

[cosmic rain]

If it's simply for rendering purposes, it might be easier to set it up via shaders, with stencil buffer checks for example.

[chrome trail]

I barely know how to even use shader graph. Unless that's possible with shader graph there's no way I can do that

[cosmic rain]

It should be possible with shader graph and/or render features(if using urp).

[rapid glen]

dang, all that did was make the vehicle accelerate slower and decelerate quicker. the issue persists unfortunately 😦

[chrome trail]

Any resources on how I can do that then?

[cosmic rain]

Maybe look up tutorials on masking geometry with stencil buffer in urp.

[arctic rune]

ok so I'm trying to get an object to move from one side of an object to another this is what I got but once it gets to one side it stops and gets stuck, I realized it was because it would play both if statements at the same time. I can't figure out how to fix this and going on google hasn't been helpful. I tried using while loops so that the if would play until it gets to one side but learned that causes unity to freeze up so I don't know what to do.

[leaden ice]

Think about your code

it doesn't make sense

it's trying to determine which way the object should move solely based on its current position

Think about whether that's actually enough information to determine which way it should be moving.

(it isn't)

FOr eample, if the object is currently in the middle should it be moving left or right?

[arctic rune]

idk but its for a school assignment where I have to build off my professor's code. This is what I'm working with

[leaden ice]

You don't know?

THink about it

Use your brain

tell me if you think you can tell based on just the position

[arctic rune]

depends on which way its currently running

[leaden ice]

exactly

So you need to keep track of that

How do you keep track of things in a computer program?

Think about how you might do that

[arctic rune]

using variables

[leaden ice]

ding ding ding

so what kind of variable could you use to track which direction the object is currently moving?

[arctic rune]

int would likely be best

using 1 and 0

[leaden ice]

Well you could do that but isn't there a better type to keep track of something that can only have two possibilities?

[arctic rune]

oh

boolean

[leaden ice]

So then - use a bool variable and then think about what the code should look like given there are two possible modes for your object and values for that variable

think about it like:

• If the object is moving right, then we are looking for a certain condition to turn around
• otherwise, we're looking for some other condition to turn around

and also - the movement needs to change based on the bool as well

[arctic rune]

ok so I got this but now the object keeps going rather than stopping

hold up wait

[leaden ice]

== to compare

you're doing = which is assigning the bool

but also you never need == true or == false

you should just do:

if (moveLeft) {
  // is moving left
}
else {
  // is moving right
}```

[spare dome]

and you are always assigning moveleft to true because it is in update

[leaden ice]

this too

[arctic rune]

oh yeah I always forget that 😭

[leaden ice]

use Start for things that should happen only at the beginning

[arctic rune]

yeah I caught that right after sending the screenshot

alr fixed it up and now its working thanks a lot for the help

[spare dome]

also since you are basing it off of the position, it would only work if the object is at the world origin (0,0,0) so if you want it to move around to different places I do not think it would work, so you could do something like this if you want

offsetposition = new vector3(0,0,0);
currentpos = transform.position + offsetposition;

if(currentpos.x >= offsetposition.x + 4){
    // do something;
}

now I have no idea if this works but you get what its trying to convey

@cosmic rain @spare dome My issue with accelerating seems to be more or less solved when I set the mass of each wheel to .1. I will have to look in to why this is the solution because there may be some other underlying issue

[weak dove]

I have an FBX file with several animations in it, and I'm importing those (Legacy) animations with the 3d model. In-game, I load in the the 3d model as an addressable. Does this also load in the animations that were imported with the model? Or do I need to load the animations as a separate addressable file?

[leaden ice]

What exactly are you loading when you load the 3d model

A prefab?

A Mesh?

[weak dove]

A prefab, yes

[leaden ice]

A prefab with an Animator?

Whatever is directly referenced in the prefab will be loaded with it. If it has an Animator with the animations, it will load that.

[weak dove]

No, there was an Animator before, but I removed it. You were helping me with that problem yesterday. Essentially I have hundreds of animations in one fbx file. Loading all the animations in the Animator was taking up a ton of memory.

I managed to replace the Animator with an Animation component by importing the animations as Legacy animations.

The memory use went down significantly. But now I need a way to fetch the one specific animation I want (via script) and play it with the Animation component.

[leaden ice]

Make it addressable or use resources

[weak dove]

Make each animation clip an addressable?

When I run the profiler while loading in the prefab, the profiler is still showing hundreds of animation clips (even though the memory use for them is lower). So I thought maybe those clips were being loaded in with the 3d model in the prefab.

[elder zenith]

Hey, kind of a weird question, but has anyone made a Task<bool> that returns true if a specfic event has been called in a timeout period, else returns false?

[swift falcon]

Guys an asset throw Editor errors from Editor folder when i try to compile. what to do

i guess if theres at least one assembly then unity will try to compile Editor folders when building the client.

[thick terrace]

i'm guessing the answer is yes that has probably happened at least once in history, but did you have a specific question 😛

[spare dome]

I would have never guessed the wheel mass, well I'm glad it works

[rapid glen]

got lucky with a unity thread that had the exact same issue. not sure why that happens though. i do remember in a previous vehicle-based project that my wheel mass was like 20kg or something and it was fine

[leaden ice]

wouldn't it just be something like (psuedocode):

bool eventHasRun;
Action listener = _ => eventHasRun = true;
myEvent += listener;
float timeElapsed = 0;
while (timeElapsed < timeout) {
  timeElapsed += Time.deltaTime;
  if (eventHasRun) {
    myEvent -= listener;
    return true;
  }
  wait one frame
}

myEvent -= listener;
return false;```

[fleet gorge]

the only concern is that if you call the function by its name instead of invoking the listener then it won't trigger eventHasRun

[leaden ice]

well why would you do that

you mean the event?

[fleet gorge]

only would happen if someone was using your code

[leaden ice]

There is no way to "invoke the event by its name" without triggering the listeners

if you mean some specific listgener function then sure but then we're not talking about an event anymore

unless I'm misunderstanding you

[swift falcon]

GUYS if framerate breaks/lags is there a way to log real life time somehow via code since game start that has passed

like i want to know if my app took 1min or 3min to finish loading (low framerate during loading, making it hard to count time)

[leaden ice]

[swift falcon]

Thanks senpai

[formal nacelle]

Hey there. I have a scene where I have a video capture from a we came going in and rendering on a rawimage under a canvas.

The user can then choose to put an overlay ontop of this via a selection keypress.

The overlays are png sequences as they are animated and have transparency. I'm currently going through the png sequence in the update, there is probably a much better way to animate the png sequence, but I havn't gone down other paths yet.

The user can then start a recording.
Currently I have a camera that is rendering to a rendertexture and then I saving each frame of the render texture, then stitching with ffmpeg to get an mp4.

The problem I'm having is thst the saving of each frame is causing the video on screen to lag.

Is there a good way to move like the saving of the images to another thread or to a buffer or something instead of direct to file,

[leaden ice]

blit the texture to a buffer (array or list of textures) https://docs.unity3d.com/ScriptReference/Graphics.Blit.html
as for the actual saving part, or saving.manipulating textures in another thread, I'm not sure about

[formal nacelle]

I'll check that out, thanks

[fallow quartz]

Instead of using inheritance for avoiding variable duplicate, is it a bad or good practice to for example in a class stats put all the stats of ur game and just make 1 constructor for each case? With this strat you can just build stats and the class will use only the ones needed

And is there any similar way to do this with methods?

[weak dove]

Why is it that having an Animator with 100s of states for different animation clips takes more memory that storing those same animation clips into a serialised list on a game object? Wouldn't the same information be held in memory in both cases?

[placid summit]

what's wrong with using inheritance? Adding a lot of unused variables is not normal - you can use components also as Unity does but inheritance is classic C#

[leaden ice]

Didn't we go through a whole discussion last week about this?

The answer is composition

This conversation #archived-code-general message

[steady moat]

Not really. At least, not in a game with an extensive statistic needs.

That being said, it could potentially be done in case of statistic modifier (percentage_damage, flat_damage, percentage_damage_versus_weak), etc. But in case of Base Statistic, it simply does not work as you might have multiple statistic of each type.

[placid summit]

I would not define attributes with string names and values - that is troublesome - the magic string situation. You can use both composition and inheritance but don't abandon inheritance

[leaden ice]

It's not a magic string situation

you can use an enum if you want, or define constants

[swift falcon]

guys so im in loading screen and i have no idea how quickly i can execute code. cause people are going to have slowe rmachines than me lol

[leaden ice]

this was a quick and dirty solution to explain composition

[placid summit]

ok I see - yes enum perhaps. I have not not gone that far with composition but it is an interesting plan. But you need a lot of code to check the attributes listed and do different work accordingly, which might be easier just using inheritance

[leaden ice]

not a lot of work really

each ability function handles its own

inheritance simply does not solve the problem

and as soon as you encounter a case where inheritance doesn't fit, you have to tear the whole system down

[placid summit]

I guess it is a bit like the component pattern - if they can all work individually its great - if they end up having to reference each other it gets complex

[leaden ice]

yes _comp_onent systems are a form of _comp_osition

[fallow quartz]

and how do you fix this if it happens

[placid summit]

I would have to look at a full example of composition - I have not struggled with inheritance before though

[leaden ice]

you tear the whole system down and built it differently. My recommendation is using a composition structure

[swift falcon]

is inheritance bad

[leaden ice]

inheritance is not bad

it's a tool

that can be misused

like any tool

it has its place

[placid summit]

composition makes me think of a game where you can add components to a robot until it does what you want. It could make a good game somehow! It definitely has a good feel, but you gotta try all tools until you find what works for you

[leaden ice]

People tend to learn polymorphism/inheritance when learning OOP and then think it's a cure-all solution for every single class of problem and that is just not what it is.

[placid summit]

there are many ways to change a light bulb

actually not really - but something something ways to do something

[arctic rune]

Huh? My editor is working fine

[thin aurora]

Your screenshot suggests otherwise

No highlighting says enough here

[arctic rune]

Highlighting for what specifically

Cause it does do highlighting for all instances of a certain variable when one is selected

[modern creek]

It's probably fine - just reopen VS by closing it then opening it within unity by double clicking a script file in the project - might have to kick unity to regenerate the project/solution files

Debug.Log() for example

transform in transform.Translate should be highlighted, Translate() should too.. your ide isn't recognizing those members

[arctic rune]

Why would it be highlighted I only have Vector3 selected

[vestal arch]

by "highlighted" we mean "colored"

syntax highlighting is highlighting different syntax elements by coloring them
like namespaces and types should be green in your current theme, but only sphereMove is in your screenshot

[arctic rune]

Ohhhh yeah I gotcha now

[fringe ridge]

so what's the proper way to move rigidbodies? MoveRigidbody glitches on collisions, just setting velocity ignores all other forces. Maybe adding to velocity and then checking if magnitude is not over a certain threshold?

[rigid island]

AddForce

MovePosition ignore collisions because its meant to kinematic

[fringe ridge]

Doesn't add force stack? The same issue as with velocity, I can't keep adding or setting it, because i want constant speed

constantly checking if the speed is above a certain threshold seems excessive

[rigid island]

oh yeah true, in that case something like a V3/Vel clamp above a threshold. afaik thats the only way

[maiden fractal]

You can do exactly same as with .velocity with AddForce alone if you just calculate the required force correctly. Calculating the force yourself may give you more freedom to do custom stuff though hence AddForce is often preferred

[rigid island]

//move input
var sqMag = rb.velocity.sqrMagnitude
if(sqrMag * sqrMag > maxSpeed)
rb.velocity = vector3.ClampMagnitude(rb.velocty, maxSpeed)
else
rb.AddForce

[maiden fractal]

Vector3.ClampMagnitude exists btw

[rigid island]

ahh wops

[fallow quartz]

if i declare in an abstract class a dictionary and then 2 classes inherit from it, the classes will have the dictionary empty so i can fill it as i want right?

so like this I have full control over what variables i want in a class, s that correct?

or is it a bad implementation

[lean sail]

All you've mentioned was a dictionary in a base class, we dont have much context as to what you'll use this for

[fallow quartz]

im just thinking other ways of building the stats/ability system

[leaden ice]

why not just make a class that has a Dictionary as a field, instead of deriving from Dictionary

[fallow quartz]

thats what i said?

[leaden ice]

oh yeah

I misread it

[fallow quartz]

yeah me 2 i had to read twice hahaha

[leaden ice]

But it's not clear what you're gaining from the abstract class here.

[fallow quartz]

well with this system i dont have to build up a full inheritance tree for abilities sharing variables

[leaden ice]

Right that's what the Dictionary gets you

[fallow quartz]

cause the dictionary is empty, i just put <Stat, float> (Stat is an enum with all the names) and then i can fill it on each class

ability class i mean

[leaden ice]

what does the abstract class get you

[fallow quartz]

all the abilities inhertir from the abstract class

so they all have the dictionary

otherwise i have to declare them in each class

[leaden ice]

but why do they need to be different classes at all

[fallow quartz]

each skill does something different and has methods

how would u approach it then

[leaden ice]

ok you want virtual method behavior

you could use delegates

but it's similar

[fallow quartz]

and place the methods on separate classes? or wdym

[leaden ice]

well with a delegate you could put them... anywhere you want

its fine though

your approach is fine. It's very similar to the List<Attribute> approach I mentioned

[pure ore]

Can static values be set like any normal value or do they reset after the next call?

[leaden ice]

you mean variables and they are normal variables

not sure why you have the impression they would reset at some point.

[pure ore]

Well I just thought, because they were static

[leaden ice]

Static means they are not attached to an instance of a type.

It has nothing to do with "resetting"

whatever that means

[pure ore]

like turning it back to false for example

[fallow quartz]

is it possible to replicate this but without using a dictionary? And btw the similar thing with methods is what u said about delegates?

[pure ore]

But thanks

[leaden ice]

Even in my List<Attribute> case, at runtime often I would build a dictionary in order to acces the attributes efficiently

[ivory smelt]

does anybody know is possible to avoid the header cloning when declaring fields in a single line?

[Header("Config")]
[SerializeField] private float _lookSensitivity, _walkSpeed, _gravityMultiplier, _jumpForce, _dashForce, _dashDuration, _dashFovChange, _dashCooldown;

[somber nacelle]

don't declare the fields on a single line like that. what's happening is the attributes are applied to each field declaration on that line, which means the Header attribute is applied for each of them

[steady moat]

It's not.

[leaden ice]

[Header("Config")]
[SerializeField] private float _lookSensitivity;
[SerializeField] private float _walkSpeed, _gravityMultiplier, _jumpForce, _dashForce, _dashDuration, _dashFovChange, _dashCooldown;```

[steady moat]

That being said, you could create your own property drawer and handle that case.

[ivory smelt]

how in earth?

how does that even work XDDD

[leaden ice]

why wouldn't it work

it's two lines

[ivory smelt]

ye ye i just tried it works but why does it now detect each field in the single line as a different one and it didnt b4

😵

[leaden ice]

it's doing exactly the same as what you just had

the only difference is Look Sensitivity was pulled out into its own group with the Header attribute

[ivory smelt]

I guess it just another Unity silly thing

Thanks!!!!

[leaden ice]

This is a C# thing

nothing to do with Unity

but alright

[ivory smelt]

Didnt know, anyways, I appreciate the help!

[somber nacelle]

as i described before, when you attach an attribute to a line of field declarations, it applies to all of them. what praetor did was take one of the fields and declare it separately and attached the header attribute to that instead of the line that has a bunch of them. this is why you see two SerializeField attributes in his example

[ivory smelt]

my bad I missed ur message

so it kinda "breaks" the loop?

[somber nacelle]

there's no "loop". it doesn't break anything. the attribute is only applied to the one field because it is only attached to the one field declaration instead of to all of them.

[fallow quartz]

is there any way to not apply header to any field?

[somber nacelle]

the header attribute is only applied to the field it is explicitly attached to. if you want to separate a field from others to show it is not part of a group then you can use the Space attribute

but header does not create any sort of grouping, it just draws a header above the field it is attached to

[ivory smelt]

oh so it applies to the first field but since the others are below they look like they belong to the same one ?

[spare dome]

it only applies to the one it is attached to

[somber nacelle]

yes because there is no spacing between the fields drawn to the inspector it just looks like a group, but the header attribute is only on the one field it is declared on

[ivory smelt]

alright so this is just a visual thing

[somber nacelle]

yes

[ivory smelt]

no hiiden logic underneath

nice

[fallow quartz]

public class CommonBehaviors {

        // Lógica de la defensa
        Console.WriteLine("Defendiéndose...");
    }

    }

    public void Defend() {
        commonBehaviors.Defend();
    }

    public void Heal() {
        commonBehaviors.Heal();
    }
}

public class Enemy {
    public Stats EnemyStats { get; private set; } = new Stats();
    private CommonBehaviors commonBehaviors = new CommonBehaviors();

    public void Attack() {
        commonBehaviors.Attack();
    }

    public void Defend() {
        commonBehaviors.Defend();
    }

    public void Heal() {
        commonBehaviors.Heal();
    }
}

so something like this would be a good implementation?

[swift falcon]

do you guys write a prefab manager?

idk addressables seem like an overkill for now

[lean sail]

Unless im missing something, both classes here are literally the same. You dont need a separate character/enemy class

[rigid island]

in what context?

[swift falcon]

well i already wrote it

Damn i learned after years of coding today that in c# u should do public fields in PascalCase

[fallow quartz]

stats inside the dictionary are not the same

[sleek heath]

both classes have the same methods, so I recommend using an interface. Even then, a ScriptableObject approach might be beneficial

[halcyon steppe]

Hi, I have the issue that my camera always looks 90 degrees to the left of the intended target.

The lookAt camPivot is supposed to deal with the vertical rotation of the camera, which works fine, and the playercam.forward part is supposed to correct the horizontal rotation to be the same as the player, which the camPivot is parented from. However with this code, the Camera always looks exactly 90 degrees left from the intended target. How do i fix this and are there better commands to copy the horizontal rotation of a transform?

[lean sail]

Populating a dictionary differently shouldnt mean you make a new class. Just change how you populate it, like possibly use SO (scriptable objects) to give it data

[bronze crystal]

my gamemanager is a singelton but when i restart game my ui elements gets lost.

Are the actual original instances you have referenced still in the scene

[bronze crystal]

yes

[quartz folio]

Or, did you reload the scene, which destroyed those instances and loaded wholly new and completely different UI elements

[bronze crystal]

this is how it looks like after restarting.

[quartz folio]

Yes, and the instances in the Sample scene are completely new instances. They are not the same objects you referenced, the original objects were destroyed and replaced when you reloaded the scene

[bronze crystal]

ah

so i need to store them in prefabs?

because i tried to store them in prefabs and it didn't really worked well.

[quartz folio]

You can have a UI singleton that doesn't use DontDestroyOnLoad and lives in the scene, so when the new scene spawns the new singleton takes over

[bronze crystal]

but this gamemanager is a singleton

[quartz folio]

And it uses DontDestroyOnLoad

[bronze crystal]

for every element that needs to survive you need to create a seperate script?

[short quiver]

Hello, I'm looking for a framework to help me abstract away series of inputs in a game for the behavior of opponents. I have an abstraction to specify control inputs to a character because I want to make sure that all bot behavior replicates what a player can technically do, so I can specify, tick-by-tick, movements, aim directions, etc.
I'd like to abstract things such that, when I say (for example), "press this input and aim at your opponent for 60 ticks", for example, without having to write out each frame of logic each time. How might I go about that?
And maybe for another example, "input move direction away from opponent for N ticks/until X happens", etc.
Obviously I'll have to write functionality to specify what it means to "aim", "at enemy", "away from enemy", etc.
And in terms of writing these instructions out, I'm fine with the code being written in C#, but it would be cool if I could use some more expressive DSL

[bronze crystal]

when one of my elemens survive, new one are put in the game, but then you get a overlap

[last hemlock]

so what's like, reasonable as far as waiting for a bugfix. like i was naively assuming they'd fix my super clear ez repro case in the next minor version, but it's been two months and 10 versions since i posted the bug

starting to worry Unity will drop 2022 LTS before even getting to it

[bronze crystal]

i dont get it what else do i need to implement to make ui survive

https://hatebin.com/ajimqoykjg

if someone can check my gamemanager

[short quiver]

my gamemanager is a singelton but when i

[naive swallow]

Why check for the canvas separately instead of just putting this script on the canvas you want to persist with this?

Also, what's with the System.Obsolete

[bronze crystal]

that àppeared because of Object.FindFirstObjectByType<Canvas>()

[naive swallow]

So don't use obsolete methods

[bronze crystal]

not needed anymore basically

[naive swallow]

and don't use Find anyway

[short quiver]

separation of responsibilities, obviously

[quartz folio]

Just use a singleton that exists in the same scene (doesn't use DontDestroyOnLoad), and don't persist any of it but the game manager.

[bronze crystal]

then you will receive a bug where to ui is destroy, and then game manager cant get the reference to it.

[naive swallow]

But if this whole object's purpose is to be the UI, then it should actually be the UI

[quartz folio]

The GameManager references the UI through the UI singleton

[short quiver]

and it is
There are a lot of ways to skin a cat

[bronze crystal]

see here what happens

i dont understand why it directly is already in the unload section

[quartz folio]

Split it up so you have a global DontDestroyOnLoad singleton that persists state,
and a separate UI singleton that doesn't persist that references the UI

[short quiver]

can you please use a thread, you're burying this whole channel

[naive swallow]

Looks like the canvas is disabled

[bronze crystal]

that is the restart canvas, activates when you die.

[short quiver]

see here what happens

[naive swallow]

The timer is what the issue is, right? The timer's not there in the next scene?

[bronze crystal]

yes and then restart canvas doesnt appear again.

[naive swallow]

The canvas is disabled

You're probably disabling it somewhere and then not re-enabling it again

#1304221299048054856

[bronze crystal]

it works now

[short quiver]

bump

[cosmic rain]

Break it down into composite parts:

• an action to do(input)
• when to do it(condition)
• how much times to repeat it
  • repeat delay
  • exit condition

If you define a data structure with these data you can virtually queue any kind of actions sequence. You can also have utility nodes like Sequence and Parallel to make several of these run in the desired order or at the same time.

[soft shard]

Correct me if im wrong, but what you described sounds similar to how a Behaviour Tree works?

[cosmic rain]

It is indeed very similar. Though a third party solution might not offer enough flexibility for their use case, which is why I'd consider writing a custom solution

[soft shard]

Interesting, I remember seeing a tutorial for a custom one built with UIToolkit a while ago, BTs seem very flexible once you can get them setup

[short quiver]

Break it down into composite parts:

[cosmic rain]

That was probably more of an ui interface for setting up and debugging the behaviour tree.
Thinking of it more as of an algorithm rather than visually connected tree of nodes, could open a lot of different use cases with it.

[soft shard]

Yeah, from what I remember it was a implementation to visualize the creation and connection of the behaviours, kind of like the Animator window, though maybe its easier to build outside of the visual tooling

[inner shuttle]

still struggling with this

[latent latch]

you need to minimize the problem before anyone can help. Create a dev build and continue printing to console

[inner shuttle]

okay

[latent latch]

It's probably something with your camera/raycasting method so figure out where

[dusk apex]

I'm going to focus on the actual problem and not assume:

he refuses to specifically see me ... ive checked the console ... but that isnt giving me any errors
So it's not throwing an error (reference exception and whatnot - the basics)
In DetectSlasher, log what the raycast hit and it's layer.
In SlasherSight log:

• if it's blind, chasing, sees player, touching, and if it's in the mesh.

[inner shuttle]

no errors at all

[dusk apex]

Of course.

[pure ore]

Gamepad input, is that something I should worry about in development or just when I'm about to publish?

[rigid island]

development , do you really want to exclude people who prefere controllers

new Unity Input system makes it stupid easy anyway

[pure ore]

Yes, but I bought InControl and don't really use it

But I guess it isn't about what you want to use, it's about what's easy to implement

[rigid island]

yeah , I just prefer the built-in solution because its Free 😄

as long as rebinding is easy, thats mainly why the new system shines as well

[short quiver]

Are there any standard naming conventions for Fluent interfaces? https://en.wikipedia.org/wiki/Fluent_interface I just want to make sure that my callers know that a given method will mutate and return itself

[leaden solstice]

Not really. Fluent API is just sugar, unless the case like Linq that you generate different object per each chain. In those cases you could add an analyzer attribute to make sure return value is used.

[viscid tree]

If Evans and Fowler "created" it, it is likely some nonsensical, self-explanatory crap, disguised as something they can sell "talks" about. 😉

The way i see it is that it is just a bunch of chained predicates, no more no less

[swift falcon]

guys is this value maximum float in unity?
it wont increase no further

3.355443E+07

very confusing

for example i tried to multiply it by 2 didnt work

[plain sphinx]

I've got an issue where Gameobjects that I Instantiate stick around after stopping the game in the editor.

Everytime stop and start the game another appears

I've tried forcing them to destroy when the scene unloads but it doesn't get called.

I'm not sure what I'm doing wrong

Reloading scripts will make them disappear

[plain sphinx]

try this

Debug.log(float.MaxValue)

If your planning on using it with large values then be careful its still accurate enough at the values your using

[swift falcon]

okay i checked and it happens to float but not doubles

I just might reset my time each in-game day or something

As for your question, a non-monobehaviour is supposed to use the constructor.

As for the actual issue; your code is coupled very poorly. I suggest you don't have d add itself to a static list like this. I don't see the point of such complexity

[crimson trellis]

yea but it create duplicates if it serializable

[thin aurora]

Currently your issue is very hard to debug since your code depends on eachother like this, which makes no sense

Why is it serializable?

I guess it's to show it in the inspector

Does the inspector show duplicates?

[crimson trellis]

i think it just a unity problem

[thin aurora]

Still, why are you doing this?

Why have a static variable that seemingly does the same thing?

Do you need to access the list from another class?

If so, use singletons and not this mess

https://unity.huh.how/references/singletons

[crimson trellis]

i just use this code to present my problem

[thin aurora]

If this is not the actual code then I suggest you just share your actual code

Nothing about this suggests that there would be duplicates

[plain sphinx]

@crimson trellis
You could do something like this to get it working.
But this is going to run everytime you make a new instance.

private static List<d> slist;

private void Start() {
    if (slist == null) {
        slist = new List<d>();

        // Do your run once code here
    }
}

[thin aurora]

This makes absolutely no difference

Even better, it's worse because your list might not exist when you need it

[crimson trellis]

i just want to make custom class that could have callbacks so i need to store them in a static list

[thin aurora]

@crimson trellis Your assignment of list from slist might very well cause the issue as Unity might fill it in afterwards with the serialized values

So I still suggest you get rid of this weird system you have and not rely on a static list

[thin aurora]

So this is an XY problem

You want something entirely different

What are callbacks here? Please explain in detail what you try to achieve

I'd rather give you a proper solution than fix the current one

[crimson trellis]

it mainly for language changes so it callback on everything that is related to language

[thin aurora]

Do you mean when the user changes their locale, so you can update strings and such that rely on it?

[crimson trellis]

yea

[thin aurora]

Then I suggest you reverse the process. Instead of adding callbacks, use events

I assume you have some sort of manager for this localization?

In short, you should probably have some singleton that manages this localization. When you update the locale, you inform this manager.

[crimson trellis]

it only gonna be harder if i dont use static , also i think this is a unity serialize problem if i use event it likely will add the event multiple times

[thin aurora]

When that happends, it triggers an event and tells any depending monobehaviours of the update. These can then update their strings

[thin aurora]

You have definitely chosen the harder approach here

Also, idk what num would be in this list?

I still don't understand what this list is supposed to contain

[crimson trellis]

it just for testing

[thin aurora]

But even then, what would this list have if your idea is to support callbacks?

You can't implement delegates into a list through an inspector. That's impossible

This is why there's events

[crimson trellis]

this isnt the actual code, the main problem is that unity create duplicates

[thin aurora]

Well, until you share the actual code that I requested there's not much I can do for you

So please either share that, or go with my suggestion

But I can ensure you your currently static approach will not work and looks horrible

[crimson trellis]

my actual code is kinda 'fixed' but im searching for a better solution

[thin aurora]

You mean the solution that I already gave?

Your question revolves around informing depending code on a change in your locale settings. This is what you explained.

The correct way would be to use events, and not callbacks. I don't see how this would even work to begin with

[crimson trellis]

my main problem is that unity create duplicates for things that is serializable ,i just want a safe way to init clas
ses and not rely on monobehaviour

[thin aurora]

I already told you that constructors exist for initialization when it comes to monobehaviours

So if you're not interested in actually fix your current system, then there you go

Not much else I can tell you at this point

[plain sphinx]

@crimson trellis
What is your code duplicating?
Is it duplicating gameobjects?
Is it duplicating prints to the console?

[crimson trellis]

the slist should have only one 'd'

[thin aurora]

If you read the issue you'd see that it duplicates class instances inside the list

[plain sphinx]

Sorry I must have missed it

[thin aurora]

It's okay. The issue is clearly the fact that they try to use a static list for some reason. Something I tried explaining to deaf ears unfortunately

So unless they improve the system, this is unlikely to be fixed

[plain sphinx]

@brah can you post the code that adds to the list?

[crimson trellis]

it in the constructor

[plain sphinx]

Have you tried the code I posted earlier?
I think that will likely fix your immediate problem.

[crimson trellis]

are u talking about a UnityEvent or a delegate? it gonna be tedious if i need to set up a scene with language elements with UnityEvent , if u r taliking about delegate it makes no difference the method will duplicates , can u give me more context about the event u r talking about

[thin aurora]

Considering you're still trying to fix this issue despite being told multiple times that your current approach is horrible:
You get duplicates because when Unity is serializing the class, your constructor gets called a second time which makes a second instance in the static list

So please start listening to advice that is given to you and get rid of this horrible system

[thin aurora]

I am talking about nothing until you start sharing your actual !code so that it becomes clear what the end goal is

So I ask again, share your code

well i 'fixed' that by whenever u use the class u check is the bool isAdded on, if false add to collection and set to true

so i dont have to rely on a constructor

Clearly you are not interested in actually being helped, or you are lazy

I suggest you seriously consider listening to advice that is given to you next time. I am no longer interested in doing so.

emmm im not sure how your idea would solve the problem,it either also make duplicates or is tedious to set up

I'm having a weird issue where GameObjects I instantiate will stick around in the game scene after stopping and starting the in-editor preview
Has anyone come across this before?

I have a MainMenu Scene which loads to a World scene
I have a "SpaceVesselController" object that does the instantiating, it is also set to Don'tDestroyOnLoad

The gameobject is the players initial SpaceVessel
Stopping and starting the game preview creates duplicates of the initial space vessel in the World scene

Reloading code after changes resets the scene
I tried using SceneManager.sceneUnLoaded += DestroyMyselfFunction() but it doesn't seem to be called when stopping the game preview

I've checked the world scene file and none of these exist there.
So they only exist when playing

FusedQyou do you have any Ideas?
I've run out of things to try

too little context, maybe try restart the editor since unity goes weird sometimes

This is a recent addition, it has no effect

SceneManager.MoveGameObjectToScene(SpaceVesselContainer, SceneManager.GetActiveScene());

I just checked and SpaceVesselContainer starts in the world scene anyway

[crimson trellis]

can u explain your problem again?

[plain sphinx]

I move from the MainMenu scene to the World Scene
When the world scene starts, I instantiate a single game object from a prefab.
There is only one instance of this object here at the moment

I stop and start the game, navigate through the menu into the world scene.
A single instance is created again,
Now there are 2!

I can keep repeating and more gameobjects all get instantiated in the same spot!

Restarting the editor like you suggested resets it back to 1

But the same issue appears again

[crimson trellis]

are u talking about the darter being created?

[plain sphinx]

yes

Darter = SpaceVessel

This is what it looks like

[crimson trellis]

your SpaceVesselController seems right sorry couldn't help

[plain sphinx]

Thanks for trying

[thin aurora]

So the issue is that they persist when you stop debugging?

[plain sphinx]

correct

I found something interesting

I put this on my gameobject, and the space vessel gets destroyed as soon as its created when loading the world scene

public void OnSceneLoaded(Scene scene, LoadSceneMode mode) {
  Debug.Log("SpaceVessel: OnSceneLoaded");    
  Destroy(gameObject);
            
}

On the other hand this has no effect

public void OnSceneUnloaded(Scene scene) {
  Debug.Log("SpaceVessel: OnSceneUnloaded");    
  Destroy(gameObject);
}

its seems to be getting loaded inbetween scenes?
I didn't think this was possible

[round violet]

so i am getting a weird issue
i have a enemy prefab, inside there is a prefab containing the skeleton mesh + a animator
if i disable this skeleton prefab, my prefab gets instantly teleported to 0,0,0 when playing

it seems linked to the ragdoll physics of my skeleton, because if i removed all parts except 1 with a rigidbody it keeps teleporting
if i disable the rigidobdy it doesnt get teleported (makes no sense since the GO shouldbt be actif on a inactive rigibody

Why do many people in unity state not apply MVC? What reasons do you have to not use it?

Is a separation into model and view still commonly applied, with different information flow paradigms?

[mellow sigil]

Didn't you already have a lengthy conversation about it last week

[dusk apex]

With Steve iirc

#💻┃unity-talk message

[shrewd tendon]

can I state that in game art the physical shape (and thus physics and behavior) is often connected to what an artist is trying to communicate to the user, and therefore behavior and presentation are intrinsically tied in assets, and therefore anything that builds on these assets cannot effectively separate model and view?

[shrewd tendon]

yes, (and at unity talk I was referred back to here)

I thought about that conversation, and I made some guesses why one would not separate for instance model and view

the reason I needed to think about it is because it goes against everything in every other software engineering project I have taken on

I hope I didn't bother anyone with the question. I'll just see where my approaches fail then (:

[mellow sigil]

Maybe now would be a great time to learn something new. If you want a similar separation of concerns, look into ECS which uses entity-component-system instead of model-view-controller

[shrewd tendon]

thanks, that sounds awesome, the reason I am asking is because I do indeed want to adopt typical game design approaches, I hope that is clear. But that does mean I need to understand the reason my old approaches fail

[eager tundra]

I really enjoy this MVC approach: https://www.jacksondunstan.com/articles/3092
same guy also introduced an alternative: https://www.jacksondunstan.com/articles/3611

[shrewd tendon]

interesting

when I was still a student I designed an architecture for an adventure game, that essentially generated the user interface from events

I really like the ecs pattern

[eager tundra]

yeah, it's great, but I feel that the current Unity implementation is a bit frustrating to work with

[naive swallow]

Often times, what you see and what makes sense in a game are different. Mega Man can stand almost completely over a pit because his hitbox is a rectangle, but his arms are wider than his feet so they are visually over nothing. This looks ridiculous, but allows for significantly better movement since you basically have built-in "Coyote time", and it allows you to jump on top of a ceiling directly above you, which can create new paths for those adventurous enough to try it.

In almost every 3D game, your character is actually a cylinder or capsule or some other simplified shape, the mesh doesn't actually do any of the physics calculations.

[shrewd tendon]

this is also quite helpful

the way I understand the code and diagrams is that model and view changes often happen at the same time

and therefore, you just needlessly complicate things if you disentangle them...

if you think I don't understand correctly or if I do get it, please let me know!

[eager tundra]

that depends on your use case, project needs, personal preferences, etc
every architecture comes with its pros and cons
having the model and view decoupled makes it easier to create unit tests and swap different implementations

but then you need to deal with the added complexity of having them decoupled in the first place

[steady moat]

From I have seen, almost every sensible implementation of a game implements a "View" and a "Model". The "controller" aspect of the MVC is only implemented when needed and is not done systematically.

That being said, there is really a few situation when it is actually needed in video game. Such situation can be when dealing with non ui-view or with multiple view for 1 "system". By example, I implemented a MainMenu that combines UI Element and World Element. Where it is possible to put the whole logic in the "View" (UI Element), I found it was more natural to add an additional layer of abstraction to handle both. Most of what is done would be inline with what a controller is usually doing.

[zealous lagoon]

Hello, I have a bit of a problem. I'm trying out unity's job system by having a big NativeArray with structs and have each job modify a part of the array, like each job does 100 elements or so, with them all accessing unique indexes (like two jobs never read/write to the same place). But there's an issue, unity finds this to be an error and asks for dependency, which is unfavorable.

Using nativeslices causes the same error. Any ideas how to split the data without copying the entire array over and over?

I print the indexes to make sure, and no slices share any indexes.

I did some googling, unbelievable it seems like copying the entire array for each job is the only way to solve this. Maybe the forums I checked were wrong as it'd be pretty silly if its the only way

Theoretically, is it possible to bypass the memory checks? Unless there's an actual problem writing to different indexes of the array in parallel, it should be fine, right?

[late lion]

The issue is that Unity's job safety system is unable to verify that each job is in fact accessing separate parts of the array and can be deemed to be safe. If the safety system's detection was more sophisticated, it might be able to handle your case, but it's not.

If these are completely separate jobs working on the same array, I think you have to use unsafe pointers instead of NativeArray to bypass the safety system.

There are unsafe versions of various NativeX collections, like UnsafeList, but there isn't an UnsafeArray, I think you just have to use pointers directly.

[zealous lagoon]

Thank you 🙏

Man, reading you guy's opinions and thoughts around the design architecture of code feels like it can be summed up with: Whatever makes sense, whatever fits and whatever isn't overkill

[bronze crystal]

rider ide says i'm not using this function, but actually i'm within my player script: GameManager.Instance.ActivateDeathUI(death);

[steady moat]

In video game, that is pretty much it. Otherwise you add an enormous amount of complexity for no gain. The end goal of "Clean Code" and pretty much every pattern is to make the development easier. If it does not, then it is pointless.

In software development, it is an other story.

[bronze crystal]

i said something wrong?

[naive swallow]

Is the function that uses that function actually being used anywhere?

Or is it in a different assembly?

[bronze crystal]

yes

[naive swallow]

If that assembly references this one, you can call it just fine, but if this one doesn't have a reference to that one, then the IDE wouldn't know about it from here

[bronze crystal]

im actually call this function from within the player script

the function intself is in the gamemanager script

weird why the ide says i dont use it

[west lotus]

There is also https://docs.unity3d.com/ScriptReference/Unity.Collections.NativeDisableParallelForRestrictionAttribute.html if you know what you are doing
