[heady iris]

Linq is a good example of the usefulness.

List<int> nums = new() { 1, 2, 3, 4, 5 };
List<int> result = nums.Where(x => x < 3).Select(x => x * 2).ToList();

x => x < 3 is an anonymous function that returns true if its argument is less than 3

[swift falcon]

The fuck?

[heady iris]

x => x * 2 is an anonymous function that returns its argument times 2

This filters the list to numbers less than 3, then produces a new list whose values are doubled

[swift falcon]

What would take me an entire function in and of itself to do, bro does in 2 lines

[heady iris]

result contains 2 and 4

You could have make the functions non-anonymous, of course

public static bool LessThanThree(int x) {
  return x < 3;
}

obviously that's a bit of a nuisance

[swift falcon]

this must be how newton felt when apple fell on head

[heady iris]

You would then do nums.Where(SomeClass.LessThanThree) instead of nums.Where(x => x < 3)

Either way, you're saying "hey, use this function!"

This is ultra-common in functional programming.

[heady iris]

and functional programming looks sort of like this: just transforming data, one way after another

[swift falcon]

what I mean more is,

if given this problem

i’d have to do each operation separately

[heady iris]

players
  .Where(x => x.health > 0)
  .Where(x => x.faction == Faction.Dudes)
  .Where(x => x.florps == 10)

operation after operation

[swift falcon]

ok what the fuck does this even do lmao

[heady iris]

well, read each line

line 2: .Where(x => x.health > 0)

what do you think that produces?

[swift falcon]

is this even correct syntax

[heady iris]

yes, i've just split it across a few lines to make it less cluttered

[swift falcon]

oh i see

[heady iris]

you can reason about each line completely separately

[swift falcon]

what does => do

[heady iris]

In this case, it is used to define an anonymous function

notice how it has no name

[heady iris]

when you define a method like this, you're saying "this class has a method called LessThanThree"

you access it as SomeClass.LessThanThree

x => x < 3 creates a function, but it's not named anything

it's just an object.

you can stuff it in a variable, of course

var lessThanThree = x => x < 3;

aka

System.Func<int, bool> lessThanThree = x => x < 3;

a function that takes an int and returns a bool

If you need to perform several statements, you add braces

System.Func<int, bool> lessThanThree = x => { Debug.Log("x is " + x); return x < 3; };

which is equivalent to

public static bool LessThanThree(int x) {
  Debug.Log("x is " + x);
  return x < 3;
}

Anonymous functions let you construct the function exactly when you need it. They can use local variables from the context they were created in.

Player admin = GetGameAdmin();
var nonAdmins = players.Where(x => x != admin);

[swift falcon]

christ i feel like a fucking idiot right now

i think this makes sense but i’d probably need to actually practice it

[heady iris]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/lambda-expressions

[swift falcon]

(not sure how to do that since i don’t really get it that well)

[late lion]

No need to run before you can walk. Anonymous methods are not required to understand delegates. They're useful for when you do understand delegates.

[heady iris]

Indeed.

public static bool IsCool(Player player) {
  return player.name == "chemicalcrux";
}

public void Start() {
  foreach (var cool in players.Where(IsCool)) {
    Debug.Log(cool.name + " is cool");
  }
}

using names makes linq especially fluent looking

players.Where(IsOnFire)

[swift falcon]

me googling what Linq is

[heady iris]

It provides a bunch of methods for working with lists

(and any other thing that looks a bit like a list)

[swift falcon]

what is .Where

[heady iris]

well, before looking it up

can you guess what a function called "Where" does?

a function that takes a list

and returns a new list

[swift falcon]

evidently not, no

[heady iris]

"give me a new list where the items match this rule"

[swift falcon]

yeah ngl would not have guessed that

[heady iris]

i do think "Filter" would be better

[swift falcon]

i would have presumed it returned where anything that met that condition was in the list

[heady iris]

LINQ uses a lot of terminology from databases

[heady iris]

bingo

oh

well, not the indices :p

yeah

i misread.

[swift falcon]

you’re chemicalcrux not misread

[heady iris]

Except is a nice one

List<int> numbers = new() { 1, 2, 3, 4, 5 };
List<int> evens = new() { 2, 4, 6, 8, 10 };
List<int> result = numbers.Except(evens).ToList();

what do you suppose the result will be?

[swift falcon]

so you’re making a new list on the fly with .Where and incrementing through that, logging anyone who is cool

and doing so in such a short space

Got Dam

[heady iris]

iterating through that, not incrementing, but yes

[swift falcon]

sorry iterating

[heady iris]

It results in very terse code

I think it's also the most obvious way to demonstrate how to use delegates

The other straightforward example are events

where you say "hey, call this method when something happens"

[swift falcon]

is there anywhere i can practice using delegates?

[mossy shard]

best way to handle knockback is to add an impulse to the target in the forward direction of the player when i am hitting?

[heady iris]

well, in the direction of the blow

which might just be the forward direction of the player

[mossy shard]

ye what i said

but when i tested it feels like a force push from star wars

even when adding momentum and such

[heady iris]

then the enemy doesn't have much drag

[mossy shard]

A you're right

i should add more drag when doing it, thanks for the suggestion

[heady iris]

You'll use them in a few contexts in Unity

For example, if you use the new input system, you'll use them a lot

InputActionReference jumpAction;

void OnEnable() {
  jumpAction.action.performed += Jump;
}

void OnDisable() {
  jumpAction.action.performed -= Jump;
}

performed is an event. You can subscribe to it by adding your method to it. You can unsubscribe by removing the method.

your Jump method gets called whenever the player hits the jump button

[swift falcon]

sorry again if wrong channel, but the hell is this now?

ill try running unity as administrator

[heady iris]

well, it says your scripts had compiler errors

[swift falcon]

i am 100% sure the error isnt in my code, it also goes to playmode successfully

[thin aurora]

Is there no stacktrace?

Does the error persist after you clear your console and trying to do something?

[swift falcon]

dont know right now

im trying to open it back

because every time i close it, it hangs in task manager, if i kill it it says "cant kill an exiting process" or "access denied" and also "project is already open"

[heady iris]

smells like a "delete library and let it reimport" situation

[swift falcon]

its currently at this "c library stage" and it errors mostly here, lets see

anyone knows what its now?

Hi sorry, my rotation works thru right analog stick. But the thing is, it works only if i push the stick from left to right vice versa and diagonaly too but it wont rotate if i push directly up or down. It need it to do that so i can make my character rotate kinda smoothly based on where i push my stick?

[stable osprey]

switch z to y

[wide fiber]

Sorry no, it works weird. because my game is like topdown, when i switch to y, it doesnt rotate like how it should. it rotates by flipping around.

[stable osprey]

well, still, there's no inputVector.z afaik

also, when do you call OnMove and OnRotate? I don't see that in the code

and on top of that, are you sure you handle rotation correctly? I can't tell from this code either

but for starters I think your stick doesn't work at all on the Y (vertical) axis because you're not using it

@wide fiber This should be enough to handle the input:

public class P_Input : MonoBehaviour
{
    public Vector3 moveInput;
    public Vector3 rotateInput;

    private void OnEnable()  => InputSystem.EnableDevice(Gamepad.current);
    private void OnDisable() => InputSystem.DisableDevice(Gamepad.current);
    private void OnMove(InputValue value)   { var input = value.Get<Vector3>(); moveInput = new Vector3(input.x, 0, input.y); }
    private void OnRotate(InputValue value) { var input = value.Get<Vector3>(); rotateInput = new Vector3(input.x, 0, input.y); }
}

or if you have your extensions set up:

    private void OnMove(InputValue value)   => moveInput   = value.Get<Vector2>().XZ();
    private void OnRotate(InputValue value) => rotateInput = value.Get<Vector2>().XZ();

[wide fiber]

ok i will try that. thank you so much!!

[stable osprey]

how to make breakpoint work on line 112 just when it throws error?

is it even possible?

[unkempt knoll]

Does someone know why this doesn`t work? Doesnt give an error, does nothing.

using UnityEngine;

public class Movement : MonoBehaviour
{
    private CharacterController controller;
    public float standingSpeed = 20f;
    Vector3 velocity;
    public float gravity = -10f;
    public float jumpHeight = 4f;

    {
        // Set speed based on the character's state
        float x = Input.GetAxis("Horizontal");
        float z = Input.GetAxis("Vertical");
        Vector3 direction = transform.right * x + transform.forward * z;
        controller.Move(direction * standingSpeed * Time.deltaTime);

        // Gravity and jumping code...
        velocity.y += gravity * Time.deltaTime;
        controller.Move(velocity * Time.deltaTime);
        
        if (velocity.y < 0 && controller.isGrounded)
        {

        }

        if (Input.GetButtonDown("Jump") && controller.isGrounded)
        {
            velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
        }
    }
}

[swift falcon]

hello, I am trying to figure out how why this internal Unity process is taking so much time to execute, and I am hoping someone can point me to where to look:

the DeformationManager.LateUpdate function is taking at least 100ms per frame in the profiler. anyone can help me understand why and how to improve it? thanks

[late lion]

Are you using the 2D Animation package?

[swift falcon]

yes I am. and it's in Unity 2023.1.1f1

[late lion]

Can you see what version you have of the package?

[swift falcon]

10.0.2

an aside note, I disabled all my monsters in the scene that use the IK skeletons, and it improved the FPS drastically. the game is running a Server/Client using Mirror

[late lion]

How many do you have?

[swift falcon]

a couple hundred

[late lion]

Ok, then I think that amount of time is expected.

You could try using the GPU skinning option if you're using URP.

[swift falcon]

ok I am using URP but haven't heard of that

[late lion]

I don't know where it's configured, I just know it's available in version 10+

[swift falcon]

okay thanks. i don't think a couple hundred monsters is many for a Server to manage across multiple scenes in my MMORPG, so I'll have to think more about how to optimize this

[late lion]

I doubt the server needs to update mesh skinning. You should look into disabling the system on the server.

And the client would only update ones visible to it.

[desert wind]

For my teleporting script, I made it so when the player is pressing E AND touching a door tagged "SafeZoneDoor" they get teleported to an empty tagged "SafeZoneCenterEmpty", or at least that's what is supposed to happen. for reasons I do not understand it gets teleported across the map instead.
https://paste.ofcode.org/EMXLQ2ZZ5de5iQ2s48dhZH
The player should be getting teleported to the transform.position of the empty gameobject

[swift falcon]

yeah that makes sense. when i'm playing as host, i'll need to have it enabled probably. but need to figure out how to only update ones visible to it. should be handled by my Spatial Hashing Interest Management

also, the game runs perfectly fine outside of the editor as separate Client and Server, this is only in Host mode that i experience all this latency and it's tough to test.

[shut cargo]

Hi, i have a question about DOTween. When i use DoFade(0f, 1f) on an image it works fine, the image fades away completely. But when i use i.e. DoFade(100f, 1f) it does nothing, but it should be reduced by about a third, right? Alpha is between 0 and 255.

*reduced by about 2/3

[late lion]

I expect DOFade uses the 0-1 range instead of 0-255.

[shut cargo]

Didn't think of that, i'll try it quickly and report back.

a late thank you for taking the time to explain all this

<3

[soft shard]

Depending on what "it doesnt work" means, I assume you mean it doesnt move when you give it horizonal/vertical input, and I assume the script is attached to a relevant object with all your values assigned correctly, I would start with debugging it - comment out all your gravity/jump logic, output what your "x" and "z" values and "direction" is, and maybe output the math your using inside Move, to make sure your getting the values your expecting, if it moves then, likely your gravity logic is affecting it, if it doesnt, likely your calculations may be wrong

[unique sparrow]

I am currently working on a gun script for a top down shooter game, but when in AR mode it instantiates too many bullets at once and I can't seem to figure out what is going wrong in the script.

[gray mural]

you probably use GetKey

but I cannot say more without further context

[unique sparrow]

Here I will send the script

I am just getting the file now

[gray mural]

what is that?

[unique sparrow]

How am I supposed to put the text in the discord chat

I am trying the links now

but it is not a long script

[gray mural]

yeah, I am looking on it already

[unique sparrow]

alright thanks

[gray mural]

I think you do really have some troubles with brackets

[unique sparrow]

What do you mean?

[gray mural]

your brackets are placed badly

also you should not compare bools

bool isPistol = true;

if (isPistol) // works
if (isPistol == true) // works too

[unique sparrow]

ok I will change it

[gray mural]

please check what method spawns bullets

[unique sparrow]

What

[gray mural]

please check what method spawns bullets

[unique sparrow]

The bullets are spawned in ShootMechanicAR()

[gray mural]

oh, I haven't it before, you start this coroutine every update

but yeah, just when button is pressed

private void Update()
{
    if (Input.GetButtonDown("Fire1"))
    {
        if (isPistol) ShootMechanicPistol();

        else if (isAR) canShoot = true;

        else if (isSniper) canShoot = false;
    }
    else if (Input.GetButtonUp("Fire1") && isAR == true) canShoot = false;

    if (canShoot) StartCoroutine(ShootMechanicAR());
}

your script ordering is quite strange

but yeah, I think it's quite logic that canShoot is true quite often

just print when coroutine starts

[unique sparrow]

ok I will try it out thanks

Ok so the shoot function is being called when the button is pressed but the same problem is occuring and it is that when the function is being called it spawns too many bullets at a time. I took the code block that you send and replaced my whole update function with it.

[gray mural]

yeah, that's just a little bit more correct method

I have already that that canShoot is true too often

you already know your issue, try to solve it now

it shouldn't be that difficult

but wait, anyway.

it's just called when button is pressed

that shouldn't spawn to many bullets

[unique sparrow]

I can show you a video of what is happening if you want

[gray mural]

yeah

but what do you even do this?

yield return new WaitForSeconds(0.5f);

it's at the end of your method

[unique sparrow]

Yeah I was just trying that out to delay it everytime the function was called

I probably just left it in by accident

[gray mural]

I see, it won't work so when it's at the end

you probably gonna use yield return null; or yield break;

[gray mural]

what a nice weapon though

[unique sparrow]

Yeah I will use that one as a minigun weapon

But I am just trying to make a simple AR now

You unlock the guns using points you get from killing zombies

AR will be cheaper than minigun

[rain minnow]

http://streamable.com

[gray mural]

they can just drag it here

@unique sparrow print what method is called

and ShootMechanicAR() should have void type too

[unique sparrow]

like print it when it is called in the debug log?

'''void IEnumerator ShootMechanicAR()'''

[gray mural]

no.

[rain minnow]

Everyone can't see the video and most ppl won't download a file from discord. It limits those who can help; just tryna help them get all eyes on it . . .

[gray mural]

void ShootMechanicAR() { ... }

[gray mural]

yeah, that makes sense, sorry

[unique sparrow]

so then I get rid of the coroutine?

https://streamable.com/4h7tma

[gray mural]

yes, print is the same like Debug.Log

[gray mural]

yes, I haven't said that it gonna fix anything

[unique sparrow]

So no IEnumerator and I just get rid of the coroutine entirely?

[rain minnow]

Keep in mind Print only works with scripts derived from MonoBehaviour. It won't work on regular classes or SOs. Debug.Log works for everything though . . .

[gray mural]

yeah, print is 3 characters less to type

also they gonna see it when they get error

[modern grotto]

What's a good way to implement status effects in my game?
I have a character that runs around and shoots multiple projectile types, and I want each type of projectile to apply a unique status effect to the enemies it hits (slow, stun, bleed, etc) and I also want to include other status effects like immunity.
What's a good approach to do this?

[gray mural]

no, you don't need it to be coroutine

it should be void, because you don't need to yield return anything

[unique sparrow]

https://hatebin.com/wjasblhgqk

this is what the code looks like now

[prisma birch]

I just upgraded versions from 2021LTS to 2022LTS and am getting a bunch of warnings related to VFX Graphs and the generated compute shaders. Anyone know how to fix these? I tried resaving/recompiling the graphs but no dice.

[gray mural]

I don't see any prints

[unique sparrow]

very last line

of ShootMechanicAR

[surreal blaze]

Hey something to bother

I been trying to follow a guide on making attack combo animations
But from what i have done im having an issue where my statemanger isnt swapping states so i cant get the animations to play at all
Im not so sure why its not swapping so i was looking to maybe get some help

[gray mural]

I see, how often is it printed?

[unique sparrow]

835 times so I believe every frame

[gray mural]

nice

[unique sparrow]

So how would I go about slowing it down so it is called not every frame but maybe once per second

well faster than one second

[gray mural]

no, it's called when you hold your button in update

here

else if (isAR) canShoot = true;

you should call that method here

else if (isAR) ShootMechanicAR();

that's because you assign canShoot to true when button is pressed

and assign it to false when it is released

bullets are spawned within time you still hold that button

[unique sparrow]

that part works fine

I just want to slow down the instantiation

[gray mural]

it was really stupid of me not to mention it

[gray mural]

no, it doesn't

I have already said you your issue

fix it

if you need it

you can slow down the instantiation by adding offset, but first fix this

[unique sparrow]

so I move '''cs else if (isAR) canShoot = true;''' right above else if (isAR) ShootMechanicAR();?

[gray mural]

you, you just remove it

don't use canShoot

just use that coroutine when you need it

and ping me, please

[unique sparrow]

So I just removed else if (isAR) canShoot = true;

[gray mural]

yes

and you remove canShoot permanently

[unique sparrow]

And I do a coroutine instead?

[unkempt knoll]

oh, sorry, no. I meant different code haha, sent the wrong thing. I wanted to send this:

using UnityEngine;

public class OpenDoorATM : MonoBehaviour
{
    public float interactionRange = 3f;
    public KeyCode interactKey = KeyCode.E;

    private bool isInRange = false;

    private void Update()
    {
   
        if (isInRange && Input.GetKeyDown(interactKey))
        {
            PerformInteraction();
        }
    }

    private void OnTriggerEnter(Collider other)
    {
       

        if (other.CompareTag("Player"))
        {
            isInRange = true;
        }
    }

    private void OnTriggerExit(Collider other)
    {
        
        if (other.CompareTag("Player"))
        {
            isInRange = false;
        }
    }

    private void PerformInteraction()
    {
        
        Debug.Log("Interaction called!");
    }
}

[gray mural]

no, I have said you everything already

you call method instead

[gray mural]

isn't it just better to do in OnTriggerStay ?

[gray mural]

yes, it is

[edgy sage]

Hi! This might be a stupid question but I'm trying to figure out why my ScriptableObject state is persisted on Unity Editor but on Android it seems to reset on each application run. For example property amountAvailable is reduced to 0 during runtime and properly persisted on the editor but is reset back to 1 on Android on each run.

Any ideas what I might be missing here? Below is simplified item class in question:

    [Serializable]
    public class Item : ScriptableObject
    {
        public ItemType itemType;
        public int amount = 1;
        public string itemName;
        public string description;
        public int maxAmountAvailable = 1;
        public int amountAvailable = 1;
    }

[unique sparrow]

Ok so once I have done that how do I offset the ShootMechanicAR?

[gray mural]

have you already fixed your error?

[unique sparrow]

I am tryint

trying to I am not completely sure what you mean

So I get rid of canShoot

[knotty sun]

That is the way ScriptableObjects work

[gray mural]

I don't see any reason for you to do shooting delay if you haven't fixed your issue yet

[unique sparrow]

and run a coroutine instead?

[gray mural]

‏‏‎ ‎

please, read my previous messages

[rain minnow]

you need to use a fireRate (basically a cooldown) and shoot a bullet when that time has passed . . .

[gray mural]

they haven't fixed their initial issue before

[gray mural]

‏‏‎ ‎

[unique sparrow]

https://gdl.space/ocuxiyofud.cpp so this is what I changed it to but now the AR acts like a pistol

[rain minnow]

isn't their problem the constant instantiation (shooting) of bullets?

[gray mural]

yeah, but your brackets are really..

[unique sparrow]

Yeah that is my problem

[gray mural]

they just have too many bullets spawned

[rain minnow]

they still need a fireRate to only spawn the bullet based on the rate of fire . . .

[gray mural]

yeah

shootDelay or smth

[rain minnow]

that's what i was originally suggesting . . .

[gray mural]

yeah, you were suggesting it before they have fixed their issue

they just need to do a coroutine

it's the best way that I see

[rain minnow]

but that is the solution to their issue . . .

[gray mural]

no, that's not

[unique sparrow]

So how do I put in the fire rate because it was working fine with the canShoot and all I needed was the firerate

[gray mural]

private bool canShoot = true;

private IEnumerator Shoot()
{
    canShoot = false;

    // some stuff here

    yield return new WaitForSeconds(2f); // do a variable from it

    canShoot = true;
}

and then just check if canShoot

quite easy

[rain minnow]

hmmm, i wonder what that 2f is for?

[gray mural]

delay

delay between shooting

[rain minnow]

exactly, that's the fireRate my dude . . .

the rate of fire at which the gun shoots . . .

[gray mural]

oh yeah, that doesn't matter

my English is bad anyway

[unique sparrow]

I dont understand how I am supposed to put this into my code. Do you want me to replace the ShootMechanicAR with the IEnumerator? And I thought I was supposed to get rid of canShoot?

[gray mural]

you have understood the logic

[gray mural]

yes, you got rid of it when we were trying to fix your previous issue

and you were not using it correctly

now you add it one more time

and yeah, now it's Coroutine

[gray mural]

delay.

[unique sparrow]

Can you put it in the code with the rest of the script so I can see where exactly I am supposed to put everything because I am still confused

[gray mural]

I have written you that coroutine already

I don't see why can't you do it yourself

[unique sparrow]

Because now it is saying on the editor that not all code paths return a value\

[gray mural]

yes, because smth doesn't return a value

probably you return just in bracket or don't return at all

[unique sparrow]

I still dont get it can you send what the update function should look like

[spark kiln]

In my 3d game of couch party type, I have 2 characters, one of which is wasd and the other is guided by an arrow. I want to tie these two characters together with the help of a chain or rope and just want them to go around together. Is there a resource or method that can help me do this?

[gray mural]

I give up, you cannot even copypaste what I have sent you
Just call this Coroutine in Update, that isn't that hard, is it?

private void Update()
{
    if (Input.GetButtonDown("Fire1"))
    {
        if (isAR && canShoot) StartCoroutine(ShootMechanicAR());
    }
}

private IEnumerator ShootMechanicAR()
{
    canShoot = false;

    // some stuff here

    yield return new WaitForSeconds(2f); // do a variable from it

    canShoot = true;
}

[wary coyote]

I am trying to code a spline follower but I am spending hours and getting nowhere stumped. I know verbally exactly how I want it to work but I can't figure out where the problems that are @#$@^ing it up are occuring.

    void Update()
    {
        if (animate)
        {
            UpdateTimeValues();
            MoveTransformsOnSpline(spline, spacing, techTree, loop);
        }
    }

    private void UpdateTimeValues()
    {
        for (int i = 0; i < techTree.Length; i++)
        {
            float velocity = (speedOverTime.Evaluate(techTree[i].time));
            techTree[i].time += Time.deltaTime * speed * velocity;
        }
    }

    public void MoveTransformsOnSpline(SplineContainer spline, float distance, SplineFollower[] followers, bool isLooping)
    {
        for (int i = 0; i < followers.Length; i++)
        {
            float t = followers[i].time; // Calculate position of each transform

            // Check if t is out of bounds
            if (t > 1 && isLooping)
            {
                t = 1 - t;
            }
            else if (t > 1 && !isLooping)
            {
                t = 1;
                animate = false;
            }
            Vector3 position = spline.EvaluatePosition(t);
            followers[i].transform.position = position;
            followers[i].time = t;
        }
    }
}```

What SHOULD be happening is every array object moves along the spline at their own speeds and positions, but relative to eachother via their initial spacing

but what IS happening is it just completely @#$@6s up in new amazing ways every time I run it, sometimes they go backwards, sometimes they loop only once

I didnt think it looked like too much code, thats not a large block to me it fits all in one screen

[jaunty needle]

using System.Collections.Generic;
using UnityEngine;

public class MessagesManager : MonoBehaviour
{
    
}
[System.Serializable]
public struct TextMessage
{
    public enum Senders { Dad, Wife, Son }
    public string textMessage;
}

How do I have this enum be accessible from both the class and the struct?

[rain minnow]

place it in its own script . . .

[jaunty needle]

Which?

Just a script dedicated to the enum?

[rain minnow]

the enum which you speak of . . .

[knotty sun]

an enum is like a class so just put the declaration at the end of your script

[jaunty needle]

Aight cool

oh damn you can just do that

[rain minnow]

as long as it's outside of the class or struct its separate and not a child of that class or struct . . .

[jaunty needle]

Hey again, when I set the constraint for the width, when I do preferred size, it chooses its own size

Unconstrained

Preferred size

[lean sail]

Only adjust the one u want to stretch, the default setting is fine for width. I believe I choose the 2nd option in the dropdown to make it scale properly, although I forgot exactly what the options are

Width meaning horizontal

[jaunty needle]

It does this

Acc it's working pretty well here

My thing is

I wanna increase the height of the sprite

from below only

[lean sail]

I assume u probably want it on the green box itself, although this is more of a UI question now

[jaunty needle]

It's in world space

[lean sail]

It has a rect transform

[jaunty needle]

When I try to use the rect tool it doesn't give me the options

[rain junco]

i have a problem rn and it doesnt let itself fixed and i already changed to private and public again nothing works

[jaunty needle]

ah, it's rect transform is... bugged out

Cuz it has a width of 1 and a height of 0

Oh I fixed it, I removed the rect transform

[jaunty needle]

How can I modify this value? As in stretching it from below

[compact spire]

Is there some sort of assembly seperation between classes under Assets\Scripts\Editor and Assets\SomeOtherFolder ? I can't seem to use any the namespaces in the editor folder in the other directories.

[leaden ice]

yes

[somber nacelle]

correct, the Editor folder gets included in the Editor assembly. you should not be using the editor assembly in non-editor code either

[leaden ice]

Editor is a special folder. All scripts in ...what box said^

[compact spire]

Phew, I was able to get around the issue by moving a class outside of Editor that is referenced by a scriptableObject

I've been trying to have a class picker in my scriptable objects

it finally works

2 days of work to avoid having to make and update a switch statement

[west path]

i am using a Parallel Job to try and make noise for a sphere and it is coming back warped. i believe this is because of my x,y,z values and how i got them. i was just wonder if anyone knows the corect way to get these values or if I did code this rights the job is just messed up because it is a Parallel job. i had it as a normal job and was working fine just slower

var x = index % Diameter;
var y = (index / Diameter) % Diameter;
var z = index / (Diameter * Diameter);

[jaunty needle]

I have this script that spawns textmessages and resizes them automatically, but if the box is too big it starts to overlap, I tried to fix it using this line of code but it didn't work

how to set cursor to the center of screen(i have lockmode locked)?

[swift comet]

I dont come from C#, using async a lot recently. I came into a lot of places where I have a private async Task<T> MethodA() that contains a call to private void MethodB() and I dont really need MethodB to be async but I need to call it from the async method because thats just how the chain of calls came down to be.
Am i doing it wrong or is that okay? Mostly asking due to the annoying warning CS1998, last option would be to supress it project wide unless I can solve it without suppresion.

private async Task<T> MethodA()
{
  await SomeTask; //etc
  MethodB() //no await, synchronous method call.
}

private void MethodB(){...}

[simple egret]

If you don't plan on awaiting anything in the method, then you can remove the async modifier, and just return a completed Task directly with return Task.FromResult(yourValueToReturn)

[swift comet]

Is that a good practise (not that im doubting the answer) just wondering if its faster to return as is, or return a task? I guess creating a task creates some overhead.

But i imagine it is nothing.

[simple egret]

Only return a Task if the caller is meant to be async and await it itself. Else the whole method chain can be non-async

What async does in reality is transform your method into a big state machine, that allows the code that's awaiting it to follow the progress of the task (running, completed, faulted). That's why you technically don't need any return on an async method that returns Task, it's all handled by the compiler for you.

With synchronous methods that still return Task or Task<T>, no state machine! You have to return a task yourself, and that's what Task.CompletedTask or Task.FromResult() does, gives you a task that's already completed

[swift comet]

Ah thanks, I somewhat knew about the state machine but not the second part. Thanks, ill give it a shot. I usually dont want to suppress warnings unless really needed 😅

[river kelp]

Hey, I am trying to make sprites flash white in certain situations, and currently I'm looking at doing it through a shader/material. The tutorial I found does this:

if I'm not mistaken, that creates a whole bunch of new materials, does it not?

Essentially every single object with this will get its own material?

[lean sail]

assuming it was accessed with through the renderer then yea it will create an instance

[river kelp]

But doing this sprite flashing thing seems so common

there has to be a common pattern for this, right? It's in every game basically

[lean sail]

a common pattern for what?

[river kelp]

sprites flashing white

on damage, etc

[lean sail]

does the tutorial u are following not work or something? im confused on what the issue is even

[river kelp]

Every material is a bunch of overhead

Ideally you would have just a few

[lean sail]

u can destroy them after they are finished being used, but u need to actually have them allocated somewhere so u arent just editing the actual material asset..

calling this overhead is like calling an int inside a class overhead

[river kelp]

N..nah.. Every material is an entirely separate drawcall

[lean sail]

https://docs.unity3d.com/ScriptReference/Renderer-material.html
i assume u are accessing the materials through here or renderer.materials. this is whats actually instantiating the material

[river kelp]

It's one thing to have like, 10 materials or whatever rendering different things in the game. Another thing entirely to have 3-5 materials per enemy in the game

Materials are like, one of the easiest ways to mess up your performance, so I would think there was a reasonable way to avoid making more..

[lean sail]

Unless you want to use a different set of sprites instead, i dont see what alternative you think there can be

[river kelp]

Well, material property blocks are one right

[lean sail]

not really
https://docs.unity3d.com/ScriptReference/MaterialPropertyBlock.html

Note that this is not compatible with SRP Batcher. Using this in the Universal Render Pipeline (URP), High Definition Render Pipeline (HDRP) or a custom render pipeline based on the Scriptable Render Pipeline (SRP) will likely result in a drop in performance.

also

Use it in situations where you want to draw multiple objects with the same material, but slightly different properties

[river kelp]

Right, so property blocks also break the batcher

[river kelp]

Right, this would be what I want

like a variable "white" amount that I can set

Anyway, the difference is pretty extreme so ideally I'd want to avoid too many

[lean sail]

I dont see how thats related to your case of wanting to edit a material at runtime

[river kelp]

editing the material creates a new instance of it, right?

Which means every object that wants to edit its materials

has different materials

[lean sail]

this is about the amount of materials on an object, not about editing them during runtime

[river kelp]

Yeah and editing materials during runtime increases the amount of materials in the game

which is bad, because every material has a huge amount of overhead

enough that 4 materials lowered that guys fps from 50 to 14

[lean sail]

have u noticed an actual performance issue yet or are just speculating

yea 4 materials... on a grid of houses...

[river kelp]

Of course it depends on the amount that's used and how many objects are in the game right

[lean sail]

Yes that applies to literally anything

profile, then worry about this if u notice an issue

[river kelp]

It would just look like rendering takes a lot of time

[lean sail]

It would also look you are thinking about this in your head and have not profiled

[river kelp]

It's the same as getting the transform basically

you don't notice it until it creeps up on you

and when you profile, it just looks like you've reached the max your computer is capable of

I know optimizing early is bad, but if you riddle your game with really slow calls there's no saving it afterwards

each of them will show up as 0.02% on your profiler

[lean sail]

theres a difference between writing clean code that you feel is sufficient for the task, and pre optimizing

no one out here intentionally writes slow code knowing theres a better solution, you only look if theres a better solution if you notice an issue

[river kelp]

I mean that goes directly against my transform get example

we all do it without caching it

we know it's slow

you will never notice it being an issue

[lean sail]

i honestly dont know what you mean with the transform example

[river kelp]

getting the transform, like

"myObject.transform"

is extremely slow

[lean sail]

who says thats what everyone does?

[river kelp]

Most code I've seen does it

[lean sail]

barely anyone actually stores references to game objects. U only need it if u need to use .SetActive

[river kelp]

no, I don't mean another game object

if you want to get your own position, what do you do?

to the object you are in?

[swift comet]

Im pretty sure its not slow as its cached

[river kelp]

'tis not, unfortunately

unless they changed it in 2022

it's an extern call

[lean sail]

please dont tell me u are using gameObject.transform

[river kelp]

you just write "transform.position" right?

[swift comet]

As far as I see it, you would cache it yourself if you use it in update or whatever frequently, otherwise its not really a bother.

[river kelp]

Sure, no need to cache it if you're just using it in start()

Still, it will never show up in the profiler, was my point

[hollow hound]

Getting "Cannot find action map 'actionMapName' in actions 'actionsName'" after renaming the action group (using new input system).
Pretty sure its a unity bug. How I can fix it?

[topaz sapphire]

if I wanted to have different functions for different types of weapons (first person shooter), should I A: have a functions that reads and ID and then executes code unique to that weapon type, B: Scripts for each weapon type called individually, C: IDK

[river kelp]

How different are the weapons

If you have one weapon that shoots blue sparks and one that shoots yellow sparks, A.

If you have one weapon that shoots bullets and another that shoots turrets or frogs, B

[topaz sapphire]

shotgun, bolt action, full auto, and projectile

[river kelp]

what is "projectile"

[topaz sapphire]

shoots projectile

the rest are hitscan

[river kelp]

I think you can put that in one class

[topaz sapphire]

oh shit

i should totally research classes in unity

im a moron

[swift comet]

😊

[topaz sapphire]

why do all those switches when i can use a zero function and call it depending on the weapon type

[river kelp]

Well, unity is not a huge fan of inheritance so y'know

you could have a component that hooks up to your shooting class

like a component with inheritance on it

[topaz sapphire]

i mean rn its just a script that hitscans from the camera with the rpm and damage referenced from a script holding the ammo, mag and weapon data

so it should be easy to add more

polymorphism thats the term

wdym? like a pannel that can be clicked to change stuff?

[hollow hound]

It disappears if I create empty oldActionMapName, but I don't want to have one.

[topaz sapphire]

also weapon data (rpm, name, ammo, etc)

ok

[river kelp]

An interface is basically a class you inherit from, just slightly different

basically it just promises a bunch of functionality

"I implement the gun interface so I promise you I have the "Shoot" and "Reload" functions."

the word "interface" really means like the section of the machine you interact with, and in code it means that you have this method of interacting with this object

Basically on a machine that has a "keyboard" interface, you know you can type.
On a class that has a "Fireable" interface, you know you can fire it like a gun.

functionally, quite similar to an abstract class

[hollow hound]

I am using auto-generated c# class from input system file. Saw similar problems on the forums, all without answers.

[topaz sapphire]

yeah thats just what im doing

its been 2 months since ive used classes and the first time in unity

[river kelp]

You'd have to show the code

[topaz sapphire]

little rusty

[river kelp]

As I mentioned, Unity isn't actually a huge fan of inheritance

it's more composition based

I really really fought against unity at first, really wanting to use inheritance, and I suffered for it.

You're better off just accepting composition and components

[topaz sapphire]

Fuck Around and Find Out

[river kelp]

We are now enemies for life

[topaz sapphire]

terry davis dint die for this man

[river kelp]

But, there are a lot of things that are very easy with composition but quite hard with inheritance

if your objects are clearly defined and have little overlap between them, inheritance is good. If your objects have random sets of functionality, composition is good

Like if some enemies fly, some enemies walk, some enemies have HP, some barrels have HP but can't walk, etc. Composition is fantastic

[topaz sapphire]

designed on concept good for random generation

not good at en mass random generation

[hollow hound]

There is no error in my code. Action maps look like this, I am using it like

_playerInput.GameInputs.Attack.started += HandleAttackInputStart;

No errors here.
I am getting "Cannot find action map 'Game' in actions 'PlayerInputBase (UnityEngine.InputSystem.InputActionAsset)'", second screenshot shows the place error from

[topaz sapphire]

idk i just hear instances of indie games struggling with random gen bc unity

[hollow hound]

What is NIS?

[river kelp]

I thought unity was alright at random gen?

[topaz sapphire]

its just what ive heard

[hollow hound]

_playerInput.GameInputs.Dash.started += HandleDashInputStart;

            _playerInput.GameInputs.Kaze.started += HandleKazeInputStart;
            _playerInput.GameInputs.Kaze.canceled += HandleKazeInputEnd;

            _playerInput.GameInputs.Attack.started += HandleAttackInputStart;
            _playerInput.GameInputs.Attack.canceled += HandleAttackInputEnd;

            _playerInput.GameInputs.CursorMove.performed += HandleCursorMove;

            _playerInput.GameInputs.Movement.performed += HandleMovementInputPerformed;
            _playerInput.GameInputs.Movement.canceled += HandleMovementInputEnd;

            _playerInput.GameInputs.WeaponSwitch.started += HandleWeaponSwitchInputStart;
            _playerInput.GameInputs.Reload.started += HandleReloadInputStart;

[topaz sapphire]

what game was it again

caves of qud?

[river kelp]

Oh, caves of qud is kind of

[topaz sapphire]

old

[river kelp]

like, for 99% of all games created by humanity

random gen is fine with unity

for fucken, dwarf fortress, I dunno if it can handle it. Not really because the random gen more because of how big the world is

I don't see where you are setting the ID

"Cannot find action map 'Game'"

"GameInputs"

[hollow hound]

Pretty sure error not in my code. Want to find a way to somehow make unity forget about that old action map. I tried regenerate entire file, resave action maps, relaunch unity and all that.

[river kelp]

don't those ID's need to match

[cedar mist]

How do i make a scene load when the player enters an area and unload the previous scene

[hollow hound]

 _playerInput = new();
 _playerInput.GameInputs.Enable();

Method param, yea

 void HandleAttackInputStart(InputAction.CallbackContext context)

[river kelp]

Sorry, again, I don't understand where you expect the action map "Game" to be

isn't your action map "GameInputs"

[hollow hound]

Yes, creation and enabling in awake, subscription in onEnable.
It worked fine with all this code before renaming. I renamed all my usage of it accordingly. Unity just doesn't want to correctly update info about it, I need a way to reset this somehow,

[hollow hound]

I am not expecting it, unity is.
I am using GameInputs as I declared in my action maps, but unity still throws error about "Game" action map about which I have no code at all.
Also, all inputs are working as expected.

Any idea how I can force it to save it? I tried to regenerate input class but no luck

[river kelp]

so this is not your code, yeah? It's just where you are getting the bug

[hollow hound]

Yes, this is unity package code, PlayerInput class

[smoky ibex]

I am following a tutorial, and theres this datatype the guy uses called "Action" what is it?

[river kelp]

well, basically a function

[hollow hound]

I'm using 2021.3, maybe it changed

[river kelp]

You can store functions and call them later

[somber nacelle]

it's a delegate
https://learn.microsoft.com/en-us/dotnet/api/system.action?view=netframework-4.8.1
https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/delegates/

[smoky ibex]

Ok, one other question

What does this syntax mean?

action?.Invoke();

I understand the Invoke(); part, but why the question mark?

[river kelp]

it doesn't do it if it's null

[smoky ibex]

Ok

I understand now

Thanks

[river kelp]

You can use that for other things too

[somber nacelle]

that ?. is the null conditional operator
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/member-access-operators#null-conditional-operators--and-
don't use it for types that derive from UnityEngine.Object through

[river kelp]

Unity objects don't like it?

because they have a special null?

[somber nacelle]

exactly. it doesn't call the overloaded == operator that unity uses to check if something is destroyed

[river kelp]

so since the underlying object is not actually null

it gets called, even though you probably expect it to be null at that point

like the object is destroyed

[somber nacelle]

yep and you end up with a missing reference exception

[hollow hound]

Sometimes you want to use ? even for unity objects.

[river kelp]

Alright. Never liked the ? operator anyway

it's rough to skim

myObject?.reference?.reference?.functioncall();

[somber nacelle]

why would you? if you destroy something on the c++ side like using the Object.Destroy method it isn't immediately null on the C# side so it could potentially throw an error if you aren't checking for null using the == operator

[river kelp]

Can you use it in the other way? Like the non-direct access way

target ? target.position : Vector3.zero;

[somber nacelle]

that's a different operator, that's the ternary operator

in this case if target is a UnityEngine.Object it has an implicit cast to bool that does a null check so doing that is perfectly fine since that side of the operator expects a bool

[river kelp]

both functionally and syntactically very similar though

myObject?. checks for truth in the reference, any reference other than null is "true", right?

[somber nacelle]

no, that does not check a bool, it checks if the object is null. the ternary operator expects a bool on the left. it just so happens that unity gave UnityEngine.Object an implicit cast to bool

[hollow hound]

If you checking component from the same go and just want to check if it exists. If go will be destroyed, script that trying to get this component will be destroyed as well. So, I think, it's better to use ? in this case because it's much cheaper computationally.

[river kelp]

I mean when you check for true/false, any value except 0 is true. It functionally does the same thing

[somber nacelle]

and if it is destroyed then ?. will not see it as null whereas comparing to null with == will. your example is literally exactly why you would want to avoid the null conditional operator.

[lean sail]

a ternary is not at all similar to a null propagating

[river kelp]

checking if a ref is null or if a bool is true is the same operation, really

[somber nacelle]

this isn't some crazy language where everything can be a bool implicitly

[hollow hound]

No. if it is destroyed then ?. will not see anything, because I specified that it is checking the same go.

[river kelp]

wacky c++

[lean sail]

https://docs.unity3d.com/2020.3/Documentation/ScriptReference/Object.html

This class doesn't support the null-conditional operator (?.) and the null-coalescing operator (??).

[river kelp]

insane python

[lean sail]

idk why it went to the 2020 version on google, but u can change it to 2023.2 even, still the same-ish message

[hollow hound]

If go of the checked component will be destroyed, then go of the checking component will be destroyed as well because it is the same go. So in this case, there is no chanve to actully make this check. Or am I am missing something?

[somber nacelle]

you can destroy a component without destroying the entire gameobject

if you know for sure that both objects will be destroyed at the same time, then sure you can use the null conditional operator. but if you decide to change things so that it isn't 100% guaranteed that the code using the null conditional operator will not run at all after the object is destroyed then you absolutely should use the == operator to check for null instead of the null conditional operator

[hollow hound]

Yeah, but if I am sure that it won't change then it's reasonable to use cheaper version.

[rugged goblet]

"Cheaper"?

[somber nacelle]

micro optimization at best, and one that isn't even worth the hassle of ensuring it won't break over just checking for null the way unity wants/expects you to

[river kelp]

Is there a performance difference?

[lean sail]

if your null checks are seriously causing any noticeable performance difference, you have bigger issues

[rugged goblet]

Null check is null check

[somber nacelle]

not sure if there truly is a performance difference, but if there is i imagine it's incredibly minor

[river kelp]

Ah, apparently it doesn't matter.

[lean sail]

this is like when someone said a reverse for loop was slower

[river kelp]

"?." is basically compiled into a normal if check

[rugged goblet]

It's just syntactic sugar

[river kelp]

left here being the code, right being the "compiled"

as you can see, they are identical

[somber nacelle]

right but this is in reference to using it for unityengine.objects which has an overloaded == operator that includes some casting. so ?. probably is faster, but not really but any measure that matters

[rugged goblet]

Nanoseconds faster but also prone to being wrong under certain circumstances

[river kelp]

Ah, so in theory if you really wanted to avoid the custom ==

But at the cost of being at the mercy of the C++ backend for whether or not you crash

[rugged goblet]

Can't imagine why you'd want to bypass their custom equality check, but there might be some obscure reason

[river kelp]

Never stop fighting against unity and their unity object tyranny. Force C# Objects, normal null checks, equality for all

[wide terrace]

Topple the hierarchy ✊

[urban estuary]

Thanks mao I actually think I know what i did wrong i didn't instruct the script to apply the new shared material to the rigid body

[boreal condor]

Hey, i am using a custom editor script and using OnSceneGUI, but it doesn't render every frame, i have to update something in the scene for it to be called, what alternatives do i have? I'm unable to look for information, whatever i find is obsolete or just doesn't work

[cosmic rain]

I don't think that's possible. Unity only updates on certain events at editing time.🤔

[boreal condor]

i have found an answer: SceneView.RepaintAll();

[cosmic rain]

Where would you call it though?

[boreal condor]

inside OnSceneGUI

or wherever you need to reload gizmos/editor visuals i guess 🤔

so in my case that would be pretty much every frame

[mystic fox]

Hi, I'm having a problem with the readiness of components on the Editor (works perfectly) vs Built exe... Is like in the .exe the components I rely on being ready are not ready and my game fails to initialize... is there any tip or guide on how to deal with this? Using v2020.3.27

[leaden ice]

Sounds like a script execution order issue

Just make sure you do self initialization in Awake and initialization that depends on other objects in Start

[gleaming peak]

can anyone help me out? Ive been working on an android app that is pretty much all just UI, and i was just working on some scripts and now, for whatever reason, i cant click anything in-game

i think maybe it might be related to multiplayer but i literally have no idea what's causing the issue, what should i do?
kinda freaking out :,)
like everything was fine and then, next thing, im compiling the game for the 1000th time and now its like the game isn't even listening to any inputs

(not sure where to post this problem so ill post it here too)

[somber nacelle]

if it's all UI and is suddenly not working then make sure that you didn't delete the EventSystem from the scene

[gleaming peak]

oh my god its literally the most basic thing, of course

thank you :,)

i cant believe THATS what was causing all this panic im embarassed lmao

i just accidentally disabled it while testing apparently

[dusky lake]

Anybody familiar with the new multiplayer play mode feature? It just freezes on me in a fresh project, all players except the main editor dont show up and their consoles freeze, no error or anything, also nothing really going on in the project as its just out of the box a fresh project created 5 mins ago

[leaden ice]

Did you write any code?

[dusky lake]

No, just everything fresh, afterwards as a test i placed a cube that i rotate by script but that didnt change anything

[leaden ice]

Does your script have a while loop in it?

[dusky lake]

No

and i didnt use the script at first test either

using UnityEngine;

public class RotateBehaviour : MonoBehaviour
{
    void Update()
    {
        transform.rotation *= Quaternion.Euler(360 * Time.deltaTime, 0, 0);
    }
}

thats all it does

[leaden ice]

Ok, well I've actually never heard of this feature

Is it experimental still?

[dusky lake]

Yes

[leaden ice]

Sounds like it's not quite ready for prime time 😉

[dusky lake]

Yeah im aware, just wanted to test it and thought maybe anybody knows a quick solution

better than not trying

[forest swan]

Hello I keep getting this message is there anyway I can fix it? It is a simple movement code and a easy fix but I am new to code and don't know what to do. Can someone Help me?

my code

[somber nacelle]

configure your !IDE as you have already been instructed to.

[tawny elk]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)

• VS Code*
• JetBrains Rider
• Other/None

*VS Code's debugger plugin is unsupported.
We recommend using VS or Rider instead.

[leaden ice]

You need to name your input actions the same as they do in the tutorial and remember to save

[forest swan]

How do I download BoxFriend?

[somber nacelle]

there's a channel for MPPM in the unity multiplayer server. the link is pinned in #archived-networking

[somber nacelle]

read the guide the bot linked

[forest swan]

I do not understand

[somber nacelle]

it is a step-by-step guide that can even be localized to your preferred language if you do not understand english. follow the guide to configure visual studio

[forest swan]

my language is not on there

[somber nacelle]

then use a translator to follow the guide. having a configured IDE is a requirement to receive help here

[forest swan]

cant reasd the pictures

reader

[somber nacelle]

well it's a good thing that the pictures are in the same language your visual studio install is in

What's a good way to implement status effects in my game?
I have a character that runs around and shoots multiple projectile types, and I want each type of projectile to apply a unique status effect to the enemies it hits (slow, stun, bleed, etc) and I also want to include other status effects like immunity.
What's a good approach to do this?

[shell scarab]

Any help with an index out of range exception?

        void OpenSpace(Index index)
        {
            int limit = index.IsFromEnd ? (values.Length - 1) - index.Value : index.Value;

            for (int i = 0; i < nextIndex - limit; i++)
            {
                values[^i] = values[^(i + 1)];
            }
            values[index] = default;
        }

index.Value = 0, index.isFromEnd = false
limit = 0, nextIndex = 1, i = 0, values.Count = 6

I feel like there shouldn't be an out of range exception here.

[somber nacelle]

array[^0] is the same as array[array.Length]
if you're gonna index from the end, start at 1

[shell scarab]

oh, that makes sense then.

[vernal compass]

Hey I'm trying to create a Scriptable Object and one of the variables I wanted to add was a Date, so that later I could organize all objects by that date! So far I haven't found a good way to store the date as a variable tho, is there a variable type for that?

[ashen yoke]

dateTime.ToLong/ShortDateTimeString

DateTime.Parse()

serializes deserializes

i ve read again it seems you dont know of DateTime at all, study it

[vernal compass]

Thank you, I'll look into it!

[leaden solstice]

What do you mean "later I could organize all objects by that date"? 🤔

Is that field for comment purpose like due date?

[vernal compass]

for context the player can pick up books and each book has a release date, I wanted the player to be able to sort the books by release date

[deep oyster]

Which part of this is the problem?

[leaden solstice]

DateTime is nice for dealing with actual localized time, but if you just want fixed value something like int year, month, day could be sufficient

[vernal compass]

after researching DateTime a bit that does make sense, thank you!

[quartz folio]

https://unity.huh.how/programming/resources/resources-folder

[leaden solstice]

There should be no extension (.prefab) for Resources.Load

[quartz folio]

There are multiple issues, that is only one of them

[deep oyster]

What are the other issues :(

[quartz folio]

Go through my link and look.

Do not disregard capitalisation.

[deep oyster]

ok, someone somewhere else said 'put it in the resources folder'. Well I changed Resources to a capital R, it didn't change anything

[leaden solstice]

I never actually tried resources folder

[quartz folio]

Why the hell would you 😛

[deep oyster]

also for some reason using the fireball moves my player one space to the left

[mystic fox]

Because it's colliding with the player... you should use layers to avoid that

[leaden solstice]

The function looks very odd that it has to find player by name

[leaden ice]

Yeah... Find abuse!

[smoky ibex]

To find the number of gameObjects with a tag, you'd use GameObject.FindGameObjectsWithTag(); but it returns an array, so I add .Length to it. But there's still a problem, if i store the length in a variable, lets say ObjCount, destroy a few objects with the tag, the value of ObjCount goes up, but doesnt come down. Are there any other methods / functions that give the number of GameObjects with a tag in unity?

[leaden ice]

What?

[deep oyster]

well this is the ontriggerenter on the fireball

[smoky ibex]

I dont know how to explain it any better

[leaden ice]

Are you getting confused by the fact that Destroy doesn't actually happen until the end of the frame?

[deep oyster]

How else am I supposed to find the player in a static function

[smoky ibex]

No, hold on

[quartz folio]

int is a value type, it will not update based on what happens in other code, the Length you get from the array has 0 relation to the Length property after it's read.

[smoky ibex]

Lemme send screenshot

[mystic fox]

I meant this

[leaden solstice]

Why would you make a static function for that

[smoky ibex]

I dont understand

[leaden ice]

You should really just use your own list to track your objects rather than using stuff like FindObjectsWithTag

[leaden ice]

Why are you expecting the int to change after you assign it?

[mystic fox]

@deep oyster Don't let player projectiles hit player

[smoky ibex]

Because its in Void Update

[dusk apex]

He may be trying to say the value will be higher than what it's supposed to be.

[leaden ice]

Show your code so we're not playing the guessing game

[smoky ibex]

void Update()
    {
        SphereCount = GameObject.FindGameObjectsWithTag("Target").Length;  //<-----This line
        Debug.Log(SphereCount);
        if(CanSpawn && SphereCount < MaxSphereCount)
        {
            MakeRandomSpawnPos();
            Instantiate(Object, SpawnPos, Quaternion.identity);
            CanSpawn = false;
            Invoke(nameof(ResetDelay), Delay);
        }
    }

[deep oyster]

I'm no- oh. I forgot to change the Fireball item's tag to Projectile

[smoky ibex]

I have prefabs being created

[mystic fox]

You should use a registry of sorts... that call is too expensive

[leaden ice]

Why would you expect it to decrease if you're spawning objects

[smoky ibex]

Because i destroy them after

Im making an AimLabs type thing

[leaden solstice]

Tag and Invoke and naming

just makes me sad

[leaden ice]

When they're Destroyed, you'll find fewer objects

[smoky ibex]

Yes

[leaden ice]

But this is all very inefficient

[smoky ibex]

What should i do instead

[leaden ice]

Use your own list

[quartz folio]

.

[dusk apex]

Find in Update isn't very nice

[leaden ice]

A whole array being allocated every frame too

[smoky ibex]

Wouldnt it be better to have an int increment each time an object is created

[leaden ice]

Yes, that would be much better than the current approach

[leaden solstice]

It's hard to say anything is nice here

Please don't name your variable Object

[smoky ibex]

Why not

[leaden solstice]

Because it is used by both Unity and C#

[leaden ice]

It clashes with System.Object and UnityEngine.Object

[smoky ibex]

How do yall get that box around your text?

[smoky ibex]

Like here

[leaden solstice]

Also it gives no information about your variable

[quartz folio]

`code`

[leaden solstice]

Surround your text with backtick

[smoky ibex]

ahh

[smoky ibex]

So would PrefabToSpawn be better?

[dusk apex]

What kind of prefab is it?

[leaden solstice]

It's better, but being specific would be better-er

[smoky ibex]

Theres more than one kind?

[dusk apex]

Be descriptive

[smoky ibex]

I thought it was just prefab

[quartz folio]

the only reason that's not great is that prefabs tend to only ever be spawned, they have little use otherwise, so ToSpawn is communicating nothing

[dusk apex]

What kinds?

[leaden solstice]

fireballPrefab for example

[smoky ibex]

Ah

[dusk apex]

EnemyFish

[ashen yoke]

or SpawnFireball(GameObject prefab)

[smoky ibex]

AimTargetPrefab

Since its a target

[leaden solstice]

This kind 🎯 ? Sure

[smoky ibex]

Yes

[leaden solstice]

Conventionally fields starts with lowercase but that's up to project

[smoky ibex]

So how can i keep track of the number of GameObjects with a certain tag?

[leaden solstice]

It's better to manage yourself, using List<GameObject> for example

[ashen yoke]

its better to use components

@smoky ibex example of the tag you are interested in?

AimTarget?

[leaden solstice]

Sure, if you have a specific script type use it

[smoky ibex]

Yeah

Its hard to follow when 3 people are helping you at once 😅

[ashen yoke]

class TrackedObject : MonoBehaviour
{
    void OnEnable() => ObjectTracking.Register(this);
    void OnDisable() => ObjectTracking.Unregister(this);
}

class ObjectTracking : MonoBehaviour
{
    private Dictionary<Type, List<MonoBehaviour>> trackedObjects;

    public void Register(MonoBehaviour mb)
    {
         if(!trackedObjects.TryGetValue(mb.GetType(), out var list)
        {
            trackedObjects[mb.GetType()] = list = new List<MonoBehaviour>();
        }

        list.Add(mb);
    }
}

barebones example

to get count you simply

public int GetCount(Type type)
{
    return trackedObjects[type].Count;
}

no tags, all automatic

failed with type

you should inherit that one

[leaden solstice]

Is it supposed to be static? Hm

[ashen yoke]

what

yes

lol

supposed to be singleton

[smoky ibex]

Uhhhhhhhhhhhhhhhhhhhhh

[ashen yoke]

nevermind then

[smoky ibex]

I aint not be understanding this

Code

[ashen yoke]

specify what you dont understand

[smoky ibex]

The whole thing, but thats because im inexperienced lmao

[ashen yoke]

ignore it then

[smoky ibex]

So dont implement it?

[ashen yoke]

i assumed you would understand this as an example of an approach

making it actually works requires a level that would click for you

so you can actually implement it from an example concept

otherwise you are in for a ride

in any case you know what is a singleton?

[smoky ibex]

No

I am new to c#

[ashen yoke]

alright, do you have any "manager" object in the scene? where various "managers/systems" are?

that supposed to be present always

each as a single instance

[smoky ibex]

I dont think so

[ashen yoke]

so currently your game is assortments of components scattered and doing their own thing

[smoky ibex]

Yep

[lyric moon]

hey uh

if i try and set a key on a dictionary that doesnt exist, will it create that key or will it return an error

[ashen yoke]

through []?

[lyric moon]

like
dict[key] = value;

[ashen yoke]

it will override whatever value is in [key]

silently

[lyric moon]

what if that key hasnt been used before

like its not in the dictionary

[ashen yoke]

it will create it

[lyric moon]

will it add the key or will it error

okay good, ty

[ashen yoke]

its a "safe" method

"safe" because it wont complain if its already present

[smoky ibex]

What is a manager

[ashen yoke]

see example above with ObjectTracking ?

there ObjectTracking acts as a "manager" its supposed to be present as a single instance, and manage a lot of other objects

[smoky ibex]

Ahh

[ashen yoke]

other names for it are "controller/system"

[smoky ibex]

So you make a manager for keeping track of objects, then the gameobject creating the targets communicates with it to know how many to spawn?

[ashen yoke]

essentially

objects register themselves in the manager

[smoky ibex]

What does that mean

[ashen yoke]

class TrackedObject : MonoBehaviour
{
    void OnEnable() => ObjectTracking.Register(this);
    void OnDisable() => ObjectTracking.Unregister(this);
}

when this component is enabled, it will register itself

when disabled unregister

[smoky ibex]

But what does registering do?

[ashen yoke]

see code in the example

[smoky ibex]

Thats what i dont understand

[ashen yoke]

what precisely

[smoky ibex]

The register method

[ashen yoke]

point at a term and say - i dont understand this one

break it down

[smoky ibex]

Im trying

Again, i've only been using unity for a bit

idk much

[ashen yoke]

i understand

im also explaining how to turn then unknown into known

break it down into parts, learn one part after another

eventually all becomes known

[smoky ibex]

What is TryGetValue?

[ashen yoke]

method of Dictionary

safe way to retreive something from it

[smoky ibex]

Btw you missing a ) in that line

[ashen yoke]

ill cut myself some slack

[smoky ibex]

Okay lol

SO

So, what about the line trackedObjects[mb.GetType()] = list = new List<MonoBehaviour>(); Why are there 2 = signs?

[ashen yoke]

the TryGetValue(mb.GetType(), out var list)

has out keyword

this is a c# feature that allows to create a variable in place of its declaration, among other things

[smoky ibex]

I understand that

[ashen yoke]

so out var list created a variable list

ok

then that line means

[smoky ibex]

I've seen it in Physics.Raycast

[ashen yoke]

that line does exactly the same as

list = new List<MonoBehaviour>();
trackedObjects[mb.GetType()] = list;

since the assignements can be chained, given that operations return something

it is evaluated right to left

[smoky ibex]

Okay, but how does this, in the end, tell me how many objects (that are somehow classed by name or tag) are in the scene?

[ashen yoke]

public int GetCount(Type type)
{
    return trackedObjects[type].Count;
}

[smoky ibex]

What is Type?

[ashen yoke]

well, its a vast topic but ok

most languages that have "classes"

are based on a thing called "type system"

[smoky ibex]

I know what a datatype is

[ashen yoke]

where a type is something that can be object

[smoky ibex]

Like int, float, char?

[ashen yoke]

so a class is a "type", a struct is a "type"

[leaden ice]

Type is a datatype that can hold a datatype 😉

[smoky ibex]

Why???

[leaden solstice]

Meta

[leaden ice]

to do stuff like .cache is explaining

[ashen yoke]

so Type object stores all that type metadata

and is used to indentify types

well not stores all of it

its more of a handle

you can get all methods, properties etc through it

or like here you can use it to identify objects

[leaden ice]

C# allows something called "Reflection" which means basially the program can inspect itself. In order to do that you need to be able to represent a datatype in a variable. So you can say like "the type of this field is int" and express that in code

there are also datatypes for Methods, Fields, etc - all the pieces of the program.

[smoky ibex]

Is this related to typeof()?

[ashen yoke]

ie if you do print( collider.GetType().Name) it will print something like "UnityEngine.Physics.Collider"

yes

[leaden ice]

yes

[smoky ibex]

Ahh

[leaden ice]

Type t = typeof(int);

now t contains the int type

[ashen yoke]

typeof resolves Type at compile time

[smoky ibex]

Oh okay yeah

[ashen yoke]

since every Type reference is unique per type, you can use it as keys in dictionaries

[smoky ibex]

So, when i register something, Type becomes the type of what i registered?

[ashen yoke]

not sure how to interpret this question

becomes the type

[smoky ibex]

Uhhh

[minor storm]

im not sure if this is a coding thing but if i have bullets that stick to my character (or around my character) and they get stuck, how would i make the bullets phase through my player but not a wall

[smoky ibex]

this ended up being much more complicated than i anticipated

[cosmic ermine]

what is the correct way to setup the indices of a quad (2 triangles)? If I'm reading my code correctly this should be what the indices look like (the paint sketch), but as you can see in the screenshot I instead seem to not have that, and also 1 of the tris is rendering the other way round for some reason.... What am I missing lol?

int VertexStart = i * 4; // if every tile takes up 4 vertices then we use i * 4 to get the correct starting vertex
int IndexStart = i * 6; // read above and replace some words, and you might understand my nonsense

UnsafeElementAt(Vertices, VertexStart).Pos = new float3(TrueWorldPos, BlockInfo.Depth) + new float3(0.5f, 0.5f, 0); // top right
UnsafeElementAt(Vertices, VertexStart).UV = BlockInfo.UV + new float2(SpriteWidth, SpriteHeight);

UnsafeElementAt(Vertices, VertexStart + 1).Pos = new float3(TrueWorldPos, BlockInfo.Depth) + new float3(-0.5f, -0.5f, 0); // bottom right
UnsafeElementAt(Vertices, VertexStart + 1).UV = BlockInfo.UV + new float2(SpriteWidth, 0);

UnsafeElementAt(Vertices, VertexStart + 2).Pos = new float3(TrueWorldPos, BlockInfo.Depth) + new float3(-0.5f, 0.5f, 0); // top left
UnsafeElementAt(Vertices, VertexStart + 2).UV = BlockInfo.UV + new float2(0, SpriteHeight);

UnsafeElementAt(Vertices, VertexStart + 3).Pos = new float3(TrueWorldPos, BlockInfo.Depth) + new float3(0.5f, -0.5f, 0); // bottom left
UnsafeElementAt(Vertices, VertexStart + 3).UV = BlockInfo.UV;

uint UVertexStart = (uint)VertexStart;

Indices[IndexStart] = UVertexStart;
Indices[IndexStart + 1] = UVertexStart + 1;
Indices[IndexStart + 2] = UVertexStart + 2;

Indices[IndexStart + 3] = UVertexStart + 1;
Indices[IndexStart + 4] = UVertexStart + 3;
Indices[IndexStart + 5] = UVertexStart + 2;

[ashen yoke]

its why i suggested to just ignore it

[smoky ibex]

Alright, thanks either way

[ashen yoke]

the winding order

you have arrows, just flip diagonal direction

[cosmic ermine]

I shall try that thanks!

[ashen yoke]

i dont know precise winding order, but i always got around just by flipping until it works lol

[leaden ice]

if float3(0.5f, 0.5f, 0); // top right is top right why is
float3(-0.5f, -0.5f, 0); // bottom right bottom right?

wouldn't that be bottom left?

float3(0.5f, -0.5f, 0); would be bottom right

[cosmic ermine]

aha whoops, that would explain things thanks!

[leaden ice]

and vice versa for float3(0.5f, -0.5f, 0); // bottom left, but you probably see that now too

[idle flax]

I have a script that writes this file to json, however "SerializeableTemperature" and "SerializableCondiment" gets included in the json file even if they're null. Is there any way I can only include them if a script initializes a new instance of them?

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

[System.Serializable]
public class SerializableObject
{
    public bool instantiatedDuringRuntime;
    public string id;
    public int prefabId;

    //Basic info
    public Vector3 position;
    public Quaternion rotation;

    //Temperature
    public SerializableTemperature temperature;

    //Capacity
    public SerializableCondiment condiment;
    //Status
    public bool status;

    public SerializableObject()
    {
        instantiatedDuringRuntime = false;
        id = "";
        temperature = null;
        position = new Vector3();
        rotation = new Quaternion();
        condiment = null;
        status = false;
    }

}

[ashen yoke]

which json lib

Json.Net has a flag in its settings object

[plucky inlet]

As they are already being "created" in your script, it makes sense, that it includes a reference to it even if its a null reference. And as cache asked, which json utility are you using?

[ashen yoke]

on how to treat null, read docs

[plucky inlet]

https://www.newtonsoft.com/json/help/html/JsonPropertyPropertyLevelSetting.htm

[ashen yoke]

https://www.newtonsoft.com/json/help/html/t_newtonsoft_json_nullvaluehandling.htm

[plucky inlet]

Double Strike 😄

[ashen yoke]

thats per prop, there is global

[idle flax]

No json lib, I just use Unity's build in.

[ashen yoke]

well

WELL

enjoy

[rain minnow]

Don't use that (default) one . . .

It's working fine for what I need it for.

[ashen yoke]

weird that you came here asking questions then

[plucky inlet]

And here we are telling you, that it does not deliver what you need it for right now 😄

Just switch to newtonsoft, its already in there in Unity latest versions I think.

[idle flax]

So I need to rewrite my code entirely just to do this one thing?

[plucky inlet]

You have one line that says, Convert or Deserialize or whatever.

[ashen yoke]

rewrite entirely?

[plucky inlet]

Rewrite that, same for other conversions

[ashen yoke]

you mean rewrite 2 Serialize/Deserialize calls?

[plucky inlet]

Its just the suggestion from this channel, use it or not. If you can live with a null object, which is fine too if you handle it correctly, stick to it. Just think a bit further that there might be more cases where you need some "advanced" functions

[ashen yoke]

the issue is that you dont want to learn new library, but you require features that are not available in the one you know

solve the issue of not wanting to learn new library

start wanting to learn it

and its a smooth sailing

[idle flax]

Sorry, I've never used a json library, don't know how it works.
It's not that I don't want to learn it, it would just be easier if I didn't have to since Unity's built in has been working perfectly for me up until this point.

But if there's no other way then I guess I'll have to look into it.

[ashen yoke]

here are the benefits, some of them

unity one is a rudimentary, blackboxed lib with no customization

[plucky inlet]

Its just one line of "using NewtonsoftJson" or something and then you just conver tyour JsonUtility.ToJson or how its called to the newtonsoft call, you find in the docs easily. Nothing more to do there and then you can use what you need from all the features

[ashen yoke]

json.net you get full source, you get intermediary objects, you can add custom serialization routines for any type, you can customize it through api or source

you can do miracles with it

[idle flax]

All right then, thanks.

[plucky inlet]

And just think ahead. if you go into development, you might be fine with your solution in your personal project right now. But if you want to learn to work on other projects and within teams, you wont meet that builtin json again probably

Nullable<long>

[lyric moon]

i know long? is a nullable long but

why cant i set my long to a value thats nullable

[ashen yoke]

show code

[lyric moon]

im tryna set a long to a long? and it dont like that

[ashen yoke]

GetLong().Value

there is no implicit cast

[lyric moon]

didnt know i had to do that
ty

[ashen yoke]

you also have to check GetLong().HasValue

my guess its the purpose of being nullable there

as an indicator of whether or not the value was present

which is bad api, a bool TryGetLong(out long) would be better

[daring spade]

Can anyone help me i keep getting a error saying The type name OnFootActions does not exist in type PlayerInput

[plucky inlet]

Show some code, cause the error is already telling whats wrong

[plucky inlet]

I guess this is more a #🖱️┃input-system issue. Can you post your stuiff there including your input asset inspector?

[daring spade]

i did

[ashen yoke]

you didnt

[ashen yoke]

can i get object path in hierarchy?

anything built in for that

[simple sable]

Hey. I have quick question.

I have a script that has some variables set as [SerializeField] since I want to assign them in the inspector. However, I also have a bool variable that, if false, the logic that uses those variables is not used.

So, my question would be if there is a way to, based on that bool, hide those variables from the inspector.

[rain minnow]

Use NaughtyAttributes to customize the inspector, buy/use Odin inspector, or create your own custom inspector . . .

[simple sable]

I'll look into it, thanks.

[latent latch]

custom inspector is an annoyance if you're constantly expanding on your data since you'll always have to edit that too to reflect changes. It's unfortunate that NaughtyAttributes is the best alternative that's free because there's still much to be desired when it comes to quick implementation of data.

[rain minnow]

Haven't seen anything built-in. You need a custom (recursive) method . . .

[ashen yoke]

        private static StringBuilder _getGameObjectPathSB = new StringBuilder();
        public static string GetGameObjectPath(this Transform tr)
        {
            _getGameObjectPathSB.Clear();
            int depth = 0;
            void ConstructPath(Transform transform)
            {
                depth++;
                if (transform.parent != null)
                    ConstructPath(transform.parent);

                if (depth != 1)
                    _getGameObjectPathSB.Append(transform.name).Append('.');
            }

            ConstructPath(tr);
            return _getGameObjectPathSB.ToString();
        }

i think this will work

forgot to - depth

[steady moat]

This is what I use (For Debug Only):

        private static string GetPath(this Transform current)
        {
            if (current.parent == null)
                return "/" + current.name;
            return current.parent.GetPath() + "/" + current.name;
        }

[ashen yoke]

that is much better

elegancy wise

[leaden solstice]

sb.Append(tr.name);
while (tr.parent) {
   sb.Insert(0, ‘/‘);
   sb.Insert(0, tr.parent.name);
   tr = tr.parent;
}

[ashen yoke]

also better

both are less efficient

[leaden solstice]

Append then somehow reverse 😄

Hello, I have a list of structs. The list has a lot of entries, and I want to be able to add and remove whenever I need to. I need to send this data to a job, however, I do not know how to turn this list into a native collection. I can do this by calling '.ToArray()' and then passing that when creating a NativeArray, but that would allocate memory and would create garbage. Is there an allocation-free like with arrays in creating a native collection from a regular list?

[ashen yoke]

this may give some information https://forum.unity.com/threads/collectionmarshal-asspan-support.1235407/

[lost dove]

Greetings gentlemen, I am writing some code to spawn projectiles around my player, in a symmetrical way based on some angle calculations.
The code is here: https://hastebin.skyra.pw/ujuhamariv.pgsql
I am using a box to demonstrate my problem, as you can see it is not symmetrical at all. I am uncertain why, and I am hoping for some insight.

front facing is upwards.

i in createProjectile is simply this:

        for (int i = 1; i < config.ProjectilesPerBurst + 1; i++)
            CreateProjectile(i);```

[leaden solstice]

NativeList?

[fervent furnace]

just use nativelist at the very beginning

[fierce osprey]

I load this data from a file and then I write it back to a file later. I could after loading convert the list to a native list but that would mean I would still need to convert the whole list to an array.

[leaden solstice]

Try putting actual number to your angle deciding logic. Imagine what should happen when burst count is 1, 2, 3 … and compare the value with your desired result

[spiral robin]

Why do i get the following error:

[lost dove]

gameObject, not GameObject.

[spiral robin]

rookie mistake, thanks

[leaden solstice]

If you are just worry about ToArray overhead you can just loop the list and copy to native collection

[fierce osprey]

I could get the underlying array from a list, but isn't true that the array might not be 100% accurate in terms of size? Like if I remove items from a list, the array is not resized, I think.

[fervent furnace]

?

a list is array

[fierce osprey]

This would be a simple solution, but it is also not the fastest.

[leaden solstice]

Why not the fastest?

[lean edge]

does anyone know why would visual studio code intellisense stop working? i tried everything and nothing works...

[rugged goblet]

You are correct, unless you use toArray which creates a new array

Typically a List has an array with a capacity bigger than the list size

[fierce osprey]

Well yes, but as far as I know the resize operation is expensive so what the list does is just changes the count and leaves the array length as is

[rugged goblet]

Resizing an array consists of making a whole new array of the desired size and copying the contents of the old array

[leaden solstice]

Just loop and copy, foreach is optimized. If you have managed collection convert to native collection a copy is pretty much inevitable

[fierce osprey]

I guess so. I would love a solution like you can do with the arrays public NativeArray<T0>(T[] array, Unity.Collections.Allocator allocator);
But instead just be able to pass a regular list when creating a native list.

Oh well

Got JSON.net working (as well as the ignore null objects setting), thanks for pointing me in the right direction @ashen yoke @plucky inlet .

One more question though, my Vector3 looks like this for some reason, any idea why?

"transform": {
        "position": {
          "x": 97.959,
          "y": 0.5990211,
          "z": 0.435000032,

What json serializer are you trying

My question may be related to code, so I'm referencing it here.

Thank you for your help!

[vivid escarp]

I am creating a simple script for a "Nurse" obj that follows a player, the only issue, it's that when i introduce the LookAt function the Nurse stop working as expected, it starts moving in random direction (sometimes) and not working as without the LookAt function, is anyone that can help me, I have searched through the internet but i couldn't be able to find any solution :C
This is my code

public class NurseMovement : MonoBehaviour
{
    [SerializeField] private float speed = 2.0f;
    private Vector3 _directionPlayer;
    public GameObject player;
    void Start()
    {
        
    }

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

    private void LateUpdate()
    {
        _directionPlayer = player.transform.position - transform.position;
        transform.LookAt(player.transform.position);
        if (_directionPlayer.magnitude > 6)
        {
            Vector3 velocity = _directionPlayer.normalized * (speed * Time.deltaTime);
            transform.Translate(velocity);
        }
    }
}```

[rugged goblet]

Not really cool to spam this to multiple channels multiple times

Just because nobody solved your problem the first time doesn't mean you copy and paste it and spam it

[ashen yoke]

you can customize serialization

by default there is no "default" serialization for vector 3
