[acoustic belfry]

its a prefab

[rich adder]

oh i didnt even think of this, then yeah thats def something very wrong if they are interacting with prefab still which I might suspect now

[acoustic belfry]

with they you mean me? well yea...................it is

[verbal dome]

Anyway focus on 1 issue at a time. What about this ^ @acoustic belfry

And make balas private, not public

[acoustic belfry]

it displayed the log over and over,
bullets left five
five
five
and five...

[acoustic belfry]

oh...

ok

[polar acorn]

How many mortem_rifle_scripts are there

[acoustic belfry]

one

i only have one mortem (name of the enemy) in the game, (wich is the owner of the script)

[thorn skiff]

i followed the sebastian lague tutorial on procedural landmass generation but i did a finite instead of infinite, im trying to add biomes and i came across voronoi diagram but i dont know where to start.

[verbal dome]

I've used this https://github.com/nol1fe/delaunator-sharp
For delaunay triangulation and voronoi diagrams

[polar acorn]

Then something keeps resetting balas back to 5. If making it private worked without giving you any errors, then it looks like your Reload() function is running more than you expect

[thorn skiff]

thats cool but i dont want the biomes to be so regular

[verbal dome]

Blend them with other noises

[acoustic belfry]

it didnt

[thorn skiff]

ill try that thanks

[acoustic belfry]

now for make it worse...for an strange reason now the bullets dont move

this is getting worse and worse...

i dont know what im doing wrong

Q-Q

[rocky canyon]

if u have a brick wall built on a broken brick and u remove that brick to replace it..

what happens to the rest of the wall?

[polar acorn]

So, since that means no other scripts are modifying balas, one of two things is happening:

1. There's more than one mortem_rifle_script and you're calling disparar on different ones
2. Reload() is resetting balas back to 5 in between each call of disparar

[acoustic belfry]

explodes, i get it

[rocky canyon]

lol.. im just sharing the pain w/ ya

😄 been there done thta

[acoustic belfry]

oh, sorry, thanks ;-;

actual scrip, how fucked up im?
https://paste.mod.gg/eshpaolvpztc/0

[rich adder]

doesnt help that most are not native english variables so its hard to tell wth is what

[polar acorn]

Put a log in Reload after the wait

see when that logs

[tight oak]

Hiya! I'm pretty new to Unity and I was wondering if I could get a quick hand with some code:

I have all of my Enemy Health, Projectile Damage, Enemy Movement code sorted, only issue isssss, the bullets collide with the Circle Collider 2D that's ONLY being used for player-detection (the enemy will only chase the player when they're spotted)

I've managed to make the bullets ignore the player character, but I'm not sure how to make that happen with component-specific stuff

How would I go about nullifying the detection-circle from being detected in the projectile code? I'd really appreciate any advice!

[acoustic belfry]

oh...sorry i forgot about that...

[acoustic belfry]

ok

[acoustic belfry]

o o h . . .
it...starts from the start...and keeps going......over over and over

wait, i think i did something wrong

        animator.Play("Base Layer.MortemRifleReload");
        reload = true;
        StartCoroutine(Reload());
    }```
that should be inside braces

w h a t

btw the enemy works the same, i dont know what went wrong, and also what that return means
this is what appeared, its on the PLAYER shooting script

    {
        Vector3 mouseposition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        mouseposition.z = 0;
        Vector3 shootDirection = (mouseposition - transform.position).normalized;

        GameObject shotgunbullet = Instantiate(shotgun_bullet, transform.position, Quaternion.identity);
        shotgunbullet.GetComponent<Rigidbody2D>().linearVelocity = new Vector2(shootDirection.x, shootDirection.y) * shotgun_bulletspeed;

        Vector3 leftDirection = Quaternion.Euler(0, 0, -10) * shootDirection; // Giro de -10 grados a la izquierda
        GameObject leftBullet = Instantiate(shotgun_bullet, transform.position, Quaternion.identity);
        leftBullet.GetComponent<Rigidbody2D>().linearVelocity = new Vector2(leftDirection.x, leftDirection.y) * shotgun_bulletspeed;

        Vector3 rightDirection = Quaternion.Euler(0, 0, 10) * shootDirection; // Giro de 10 grados a la derecha
        GameObject rightBullet = Instantiate(shotgun_bullet, transform.position, Quaternion.identity);
        rightBullet.GetComponent<Rigidbody2D>().linearVelocity = new Vector2(rightDirection.x, rightDirection.y) * shotgun_bulletspeed;

    }```

[slender nymph]

1. you need to get your !IDE configured (see message below) 👇
2. i'd recommend a physics query for your detection circle instead of relying on a trigger message. you can use a Physics2D.OverlapCircle to periodically check that area and it will also allow you to pass in a layermask to filter what layers are even detected

[eternal falcon]

💡 IDE Configuration

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

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• :question: Other/None

[tight oak]

Oh my gosh THANK YOU I've been trying to figure out for AGES why my VisualStudio wasn't VisualStudio-ing like everyone else's

[tight oak]

So would you say for a periodic check I should put it into a void Update()? Or would Physics2D.OverlapCircle be a void function in of itself?

[slender nymph]

OverlapCircle is a method you can call in Update (or where ever)

[tight oak]

Awesome! Thank you for the help, you're the best :]

[acoustic belfry]

Hi, i have good news and bad news.
I managed to fix the issues, now the bullets decrease, and the bullets move, and when it empties it enters into the coroutine where it restarts the bullet amount...
My issue now is...the reloading animation doesnt work

[forest orbit]

why can't I reference my JoinBtn here?

[slender nymph]

you can't just have arbitrary code outside of a method

[polar acorn]

It needs to be in a function

[forest orbit]

ahhhh yea right

[acoustic belfry]

hey btw, why my animation doesn't triggers?

it should

        {
            animator.Play("Base Layer.MortemRifleReload");
            reload = true;
            StartCoroutine(Reload());
        }

    }```

this script works, cuz everything works but the animation

[rich adder]

this doesnt make much sens

[polar acorn]

Put a debug log before the animator.Play line

[rich adder]

if its true why are you setting it to true again

[acoustic belfry]

i set it to false for default

[slender nymph]

do you assign true anywhere else? because if not, then naturally that if statement can never evaluate to true

[forest orbit]

what am I doing incorrectly here?

[polar acorn]

What does the error say

[acoustic belfry]

oh no, i set it in shooting.
But the script its supossed to execute an animation and a coroutine, and well...the coroutine in theory works cuz it affects another value, but the animation doesnt

[slender nymph]

have you actually verified that line is running

[acoustic belfry]

im now gonna

[slender nymph]

but also, like nav pointed out, that assignment to reload is 100% pointless there

[acoustic belfry]

yep it works

[acoustic belfry]

huh

[slender nymph]

wdym "huh"? reload is already true there, it is pointless to assign true to reload there

[polar acorn]

If reload is true, you set it to true. What do you expect that to accomplish

[acoustic belfry]

ah, my bad, the coroutine sets it to false

listen, i checked the log, and it works, the whole bool works

the issue here is, the animation doesnt

[slender nymph]

nobody is saying that the bool doesn't work. we're pointing out that assigning true to it there is pointless.

you're literally doing if reload is true assign it to true

[acoustic belfry]

i...didnt saw that

sorry

[slender nymph]

then pay attention to what people tell you

[acoustic belfry]

sorry

but well, that's fixed, but what's not is, why the animation doesnt run?

[slender nymph]

anyway, show your entire console window when you see the log that proves your animator.Play line is running

[slender nymph]

stop hiding your warnings

[acoustic belfry]

       {
           Debug.Log("reload scene");
           animator.Play("Base Layer.MortemRifleReload");
           StartCoroutine(Reload());
       }

   }```

[lethal smelt]

that's a lot of clones...consider using pooling

[acoustic belfry]

the clones are bullets

[slender nymph]

object pooling is 100% above this person's pay grade at the moment

[acoustic belfry]

what do you mean using pooling?

[lethal smelt]

well maybe it is

but it'll def be better than this

[acoustic belfry]

im sorry im just trying to make a game in Unity for the first time

[lethal smelt]

look for tutorial

[acoustic belfry]

not maybe, IT IS

[slender nymph]

okay now pay attention to what people tell you. #💻┃code-beginner message

[acoustic belfry]

i did now, there's nothing very important for now

[slender nymph]

show it

[acoustic belfry]

ok

[slender nymph]

also turn off collapse mode so that the logs are shown in the proper order

[acoustic belfry]

ok

[lethal smelt]

oh now that I'm looking at it...unity 6 looks a lot diffrent huh

[acoustic belfry]

here is

[lethal smelt]

I still haven't updated yet lol

[acoustic belfry]

it says there's an animation issue for the Tuetue (bird meele-based enemy)

nothing about the Mortem (proyectile-based enemy and the one highlater btw)

[polar acorn]

Well there's like 900 of them, did you consider maybe some of them are related to the one that isn't playing the animation

[lethal smelt]

I think the controller in animator component is empty

[acoustic belfry]

i clicked all of them, 100 of them

[lethal smelt]

unity does this to me too every now and then

[slender nymph]

there are 900 of them though

address that then try again

[acoustic belfry]

i meant, i clicked all of them, :<
originally where of the Mortem and the Tuetue, but then i fixed something, and the error faded away...but the reloading animation's still missing

[verbal dome]

Show this but with Collapse enabled

[acoustic belfry]

ok

[slender nymph]

or just fix that issue and try again with collapse disabled since we want to see when any warnings happen around that specific log that shows when you call animator.Play on the shooting object

[acoustic belfry]

oh, it was that i forgot to add it to the object
o - o

xd

But now i have another issue..................................................
the animation executes, but doesn't wait till it ends to return to shooting, and then gets in a loop of "reloading" and "shooting" at the same time

but hey, its an advancement

[slender nymph]

okay do you have any logic that prevents it from shooting during the reload animation?

[acoustic belfry]

w e l l

no

[acoustic belfry]

ahh, you mean the logic of shooting

in theory

i mean, it needs bullets to do it, and thats earned in the coroutine, "wich says that it would give the bullets to the enemy after the animation ends"

but doesnt work

    {
        while (reloadAnimation)
        {
            yield return null;
        }
        reload = false;
        balas = cantidadDeBalas;
        //done reloading
    }
}```

[polar acorn]

What changes reloadAnimation

[acoustic belfry]

i think i did a miscalculation, im fixing it now

its supossed to be the animation...looks like i did it wrong

        if (reload == true)
        {
            Debug.Log("reload scene");
            animator.Play("Base Layer.MortemRifleReload");
            reloadAnimation = animator.GetCurrentAnimatorStateInfo(0).IsName("MortemRifleReload");
            StartCoroutine(Reload());
        }```

[polar acorn]

You just set the animation to MortemRifelReload. You already know exactly what the current animation is. Why not just set reloadAnimation to true there?

Code runs, one line at a time, top to bottom

[acoustic belfry]

wat

[polar acorn]

You set the animation, then on the next line immediately check the animation

[acoustic belfry]

yeah

[polar acorn]

it's going to be what you just set it to

why bother checking it there

[acoustic belfry]

i dont get it

ah, im checking it

for make the coroutine also check it

and wait till it ends

#💻┃code-beginner message

[polar acorn]

Okay, let me ask you a question.

int x = 7
bool isXSeven = x == 7

Is there any universe in which isXSeven is false

[acoustic belfry]

no...

[swift crag]

I think you misunderstand what this line of code does

reloadAnimation = animator.GetCurrentAnimatorStateInfo(0).IsName("MortemRifleReload");

This does not perpetually check if the current animation is "MortemRifleReload", over and over

It checks if, at this moment in time, the current animation state name is "MortemRifleReload"

That's it.

It doesn't matter if the animation state changes sometime later

reloadAnimation will remain true

[acoustic belfry]

o h

then what i should do for acomplish what i need?
make that when bullets reach zero (reload becomes true) executes an animation, and waits until that animation ends for make bullets return to it original value

[swift crag]

well, you currently have code that loops forever until reloadAnimation becomes false

perhaps you should do something to make reloadAnimation become false there

[acoustic belfry]

ooooooh, now i get it

but the issue is.........................what? specificly
sorry for my noobness

[swift crag]

You already know how to check if the current animation state is named "MortemRifleReload"

you have explicitly written a line of code that does this

[acoustic belfry]

yeah, i know that, but i want to do the oppositive...

im getting pretty lost here

[swift crag]

well, that's what the ! operator is for...

but in this case, I'm pretty sure you do just want

[acoustic belfry]

what does this? i thought it detected till the bool reloadAnimation, wich is the equivalent to the animation, ended
yield return null;

[acoustic belfry]

oooooooooooooooh, i forgot about em

[swift crag]

while (condition) {
  condition = ...
  yield return null;
}

[swift crag]

no, not at all

yield is a keyword used inside an enumerator method

it causes the enumerator to stop and either exit completely (yield break) or produce a value yield return)

with Coroutines, you generally just yield return nothing -- thus, yield return null

Unity resumes the method once every frame. When the method hits a yield, it stops again.

[acoustic belfry]

so for now i just wrote it just as a decoration

[swift crag]

it is very important

while (true) {

}

This will freeze your game

It runs forever.

[acoustic belfry]

aaaaaaaaa

got it

[swift crag]

while(true) {
  yield return null;
}

If you run this as a coroutine, it will run the loop once per frame

it hits yield return null and stops

then Unity resumes it one frame later

You should check if the animation is still running once per frame

Once it is no longer running, you can exit the loop

[acoustic belfry]

but how do i do that?

thats what im seeking and what i thought i did well

[swift crag]

you already know exactly how to check if the animation is running

[acoustic belfry]

the thing

but how do i exit the loop?

[swift crag]

a while loop terminates when its condition becomes false

[acoustic belfry]

cuz it looks like, atleast when i try it, that doesnt ends, and the mortem is just there having a seizure trying to reload an infinitely empty rifle

[swift crag]

you can update the variable you're using as its condition inside the loop

[acoustic belfry]

ooooooooooooooooooooooooooh

[swift crag]

bool whatever = true;

while (whatever) {
  whatever = Time.frameCount == 1000;
  yield return null;
}

[acoustic belfry]

but i want that time to be the exact of the animation

[swift crag]

this will run until the frame count is 1000, and then the loop will exit (one frame later, actually, due to the order I put things in)

[swift crag]

yes, and again: you know how to check if the current animation state is "MortemRifleReload"

i'm trying to get you to put two and two together here

[acoustic belfry]

oh, ok

[acoustic belfry]

i think i did something wrong, it scapes the loop yey...But it doesnt wait till the anim ends

    {
        while (reloadAnimation)
        {
            reloadAnimation =! animator.GetCurrentAnimatorStateInfo(0).IsName("MortemRifleReload");
            StartCoroutine(Reload());
            yield return null;
        }
        reload = false;
        balas = cantidadDeBalas;
        //done reloading
    }
}```

[swift crag]

this checks if the reload animation is not "MortemRifleReload"

then it...starts another coroutine

get rid of StartCoroutine entirely and don't negate the IsName check

[polar acorn]

Why are you starting another coroutine inside the coroutine

Like, what did you think adding that line would accomplish

[acoustic belfry]

eh, looks like i didnt realized

[polar acorn]

Read your code as your typing it

[acoustic belfry]

aaah, that thing came with the paste

[polar acorn]

every line does something

[acoustic belfry]

i copy pasted a thing from another

[acoustic belfry]

ok

[acoustic belfry]

cuz i wrote that in the wrong place and then i just chopped and put it on there.....but looks like with a friend

[acoustic belfry]

what you mean with the IsName check, but i deleted the extra coroutine...but still doesn't wait

[polar acorn]

What are you setting reloadAnimation to inside the loop?

[acoustic belfry]

wat

[unborn valley]

i've been re-reading some of my old Java code, turns out old me did NOT know about indenting or spaces. i legit typed stuff like this

if(posX-15<0){posX=16; xAccel=(1-xAccel)/2;}
if(posX+15>width){posX=width-16; xAccel=(1-xAccel)/2;}
if(xAccel>15){xAccel=15;}
if(xAccel<-15){xAccel=-15;}
if((abs(xAccel)<1)&&(!right)&&(!left)){xAccel=0;}

THIS PHYSICALLY HURTS TO READ WHAT

[polar acorn]

What are you setting reloadAnimation to inside the loop?

[polar acorn]

If it doesn't hurt you to read your old code you aren't improving fast enough

[unborn valley]

you know that's actually such a good motto

damn

yea im keeping that one lol

[acoustic belfry]

i mean, the anim

i feel like im doing something wrong

[swift crag]

if you don't understand what any of the code you're writing is actually doing, then you seriously need to stop what you're doing and use something like !learn to get a handle on this

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[polar acorn]

Specifically, what are you setting the value to?

What value are you reading and setting that boolean to

[acoustic belfry]

        {
            Debug.Log("reload scene");
            animator.Play("Base Layer.MortemRifleReload");
            reloadAnimation = animator.GetCurrentAnimatorStateInfo(0).IsName("MortemRifleReload");
            StartCoroutine(Reload());
        }```

[polar acorn]

In the coroutine

in the loop

what are you setting it to

[acoustic belfry]

aaah, same

    {
        while (reloadAnimation)
        {
            reloadAnimation = animator.GetCurrentAnimatorStateInfo(0).IsName("MortemRifleReload");
            yield return null;
        }
        reload = false;
        balas = cantidadDeBalas;
        //done reloading
    }```

i feel like im doing something wrong

wrong af

[polar acorn]

Okay, and what does this mean:

animator.GetCurrentAnimatorStateInfo(0).IsName("MortemRifleReload")

What is this checking?

[acoustic belfry]

if the state is reload

originally i set it to null in the corountine

the oppositive

but i decided right now to change it to positive

for test if that may help

it didnt help

[unborn valley]

im spanish and it took me like way too long to realize the bullet count was written in spanish, this bilingual stuff messing with me 😭

[acoustic belfry]

xdxdxd, piola pana :3

[swift crag]

This looks reasonable to me.

It checks if the current animation state is named "MortemRifleReload" and stores the result in reloadAnimation

If that ever becomes false, the loop ends

[verbal dome]

The issue here might be that the animation state doesn't really change instantly when you call Play, but at the end of the frame or in the next frame instead

But your code expects that it does

[tiny oxide]

if (playerRb.linearVelocity.y < 0)
{
    isFalling = true;
}
else
{
   isFalling = false;
}
Debug.Log(playerRb.linearVelocity.y);

I have a player's rigidbody that is affected by gravity, yet its linear velocity stays at 0 when it is moving downwards. What am I missing?

I expected the linear velocity to become negative

[swift crag]

I was thinking about that a bit earlier...

[wintry quarry]

Can you show the full script? Is it actually moving via physics?

Also you should log that value with a label so you know what you're looking at in the logs

Debug.Log($"Velocity is {playerRb.linearVelocity.y}");```

[acoustic belfry]

you mean that i need to change the animation in the shooting phase, and after that it would work?

i got lost

[tiny oxide]

Well, the gravity is moving the game object via physics in the negative y direction.

And it's on in the rigidbody, let me go ahead and send you the script.

using System;
using UnityEngine;

public class PlayerController : MonoBehaviour
{
    private Rigidbody playerRb;
    private BoxCollider boxCollider;

    public GameObject propeller;

    private float gravityModifier = 25.0f;
    private float verticalSpeed = 10.0f;
    private float horizontalSpeed = 5.0f;
    private float propellerSpeed = 10.0f;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        Physics.gravity *= gravityModifier;
        playerRb = GetComponent<Rigidbody>();
        boxCollider = GetComponent<BoxCollider>();
    }

    // Update is called once per frame
    void FixedUpdate()
    {
        // Gets player input
        float horizontalInput = Input.GetAxis("Horizontal");
        float jumpInput = Input.GetAxis("Jump");

        // Applies force upwards
        float verticalForce = jumpInput * verticalSpeed;
        playerRb.linearVelocity = new Vector3(playerRb.linearVelocity.x, verticalForce, playerRb.linearVelocity.z);

        // Applies forces horizontally
        float horizontalForce = horizontalInput * horizontalSpeed;
        playerRb.linearVelocity = new Vector3(horizontalForce, playerRb.linearVelocity.y, playerRb.linearVelocity.z);

        // Spin the propeller respective to the player's vertical velocity
        propeller.transform.Rotate(Vector3.up * verticalForce * propellerSpeed);

        Debug.Log($"Velocity is {playerRb.linearVelocity.y}");
    }

}

[wintry quarry]

you seem to be resetting the vertical velocity to 0 every frame:

playerRb.linearVelocity = new Vector3(playerRb.linearVelocity.x, verticalForce, playerRb.linearVelocity.z);```

verticalForce is 0 if there's no input on the Jump axis

[tiny oxide]

I see, makes sense.

[wintry quarry]

You should be seeing this in the form of really unrealistically slow falling

[tiny oxide]

Should I make an if statement to not change the linear velocity if the jump input is 0?

Seems reasonable.

[wintry quarry]

that would be pretty normal yes, only jump if you're jumping

[warm owl]

Hello, i have a little bit of problem. i made a settings in my game, a pretty simple one. and i dont really understand why for example ticking in the checkbox to change from windowed mode to full screen. works one way, but the other dont.

So only the set value is working which i set in the inspector

[wintry quarry]

you'll have to show us what you're talking about - code and screenshots from the editor

[tiny oxide]

Works a lot better when I only jumped when jumping, thanks for the help.

[warm owl]

Here's a video, let me copy the code too

Oh

[swift crag]

you'll need to record an MP4

[warm owl]

ah

finally

public void SetFullscreen(bool isFullscreen)
{
    Screen.fullScreenMode = isFullscreen ? FullScreenMode.FullScreenWindow : FullScreenMode.Windowed;

    PlayerPrefs.SetInt("Fullscreen", isFullscreen ? 1 : 0);
    PlayerPrefs.Save();
}

[rich adder]

how you call SetFullscreen?

[warm mason]

hi guys, i've been learning C# recently and i have a question, when / how much do i need to know before switching over to unity

i have a good concept of all the fundamentals, i am comftorable with OOP, etc.

is that all I need to start making games?

[wintry quarry]

I would say most people start learning unity without even knowing the bare basics of C# so you're probably well ahead of the game

[warm mason]

how though

cuz

i mean

surely you'd have to learn the syntax and basics on what you're looking at like, whats a class, whats a method, learn about inheritence, how to store data and what different data types are, etc.

or

i guess you could just learn it through unity but

if you look up a unity tutorial, they never teach you that stuff they just tell you what code to put you konw?

idk

do you think the part for me now is just learning the different classes/methods Unity uses and how to incoperate that into my game?

[drifting cosmos]

you can learn them both at the same time

[blazing ice]

what do you mean the reference isnt set to an instance of an object i clearly set it in the start() function....

[drifting cosmos]

capital P?

[blazing ice]

no i keep forgeting rigidbody 2d is different from standard rigidbody thats the reason why lol

i hate 2d!!!

[drifting cosmos]

why

[blazing ice]

im just used to the way 3d works so small errors like typing the wrong rigidbody makes the code break and i dont realize it lol

[lusty star]

Yeah its some pretty tiny amount i agree with anime person

[rich ice]

"anime person"

[rich ice]

screenshots are fine, its just about making sure the code is as readable as possible. makes fixing the issue a lot easier

in the screenshot they sent, we cant see which line the error is on. we can take a guess, but its still a lot easier if we can just see the numbers on the side

[topaz mortar]

Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Mouse.current.position.ReadValue());```
What is the difference between these two?
I understand the first uses the old input system and the 2nd the new input system, but what does that actually mean?

I'm using the new input system for my player movement with the keyboard too, but I don't understand how this translates to the mouse? Since I haven't set up the mouse in my inputs?

[timber tide]

There's a thing called an Event System on your scene where these input events are setup

[topaz mortar]

Hmm, I remember that should be there, but it's not?

I'm using this, but haven't set up anything for the mouse, or is that just already included?

[timber tide]

Uh, make a ew game object and add EventSystem and Input Module if it's not automatically added

[topaz mortar]

But my game works without it?

[timber tide]

Ah, thought you were saying it didnt work. Actually maybe you don't need it for coordinates now that I think about it

[topaz mortar]

Ah no, it works, I just don't understand how lol

[timber tide]

Input class is legacy, but it includes standard properties

[topaz mortar]

I'm using this one now:
Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Mouse.current.position.ReadValue());

But from setting up the keyboard movement, I thought I had to catch a mousemove event or something

like for keyboard movement I'm doing:

{
    _moveInput = inputValue.Get<Vector2>().normalized;
}```

[timber tide]

Right, Mouse.Current is based on the newer input system, but you can still use the legacy too.

[astral falcon]

highly advice to go to the new one tho. and mxiing both sounds even worse

[topaz mortar]

I just posted the first line as example, I'm trying to use the new system

[timber tide]

I use legacy for when I can't be bothered mapping keys

old fashion poll your input

[topaz mortar]

I wonder why this line works, without me setting up the input in my input asset:
Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Mouse.current.position.ReadValue());

where does "Mouse" come from?

[timber tide]

It's some standard property. Unity recognizes your device and input from your mouse

[astral falcon]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/manual/Mouse.html

[topaz mortar]

So would this work for controllers too?

[timber tide]

That exact property? Doubtful

Kinda where the 'new' input system shines though where you can have multiple different controller profiles that map similar operations

[topaz mortar]

So how do I set this up with the new input system?

Because I thought I was using the new input system with this

[lavish magnet]

How would you guys recommend coding a rolling barrel? I ahve a capsule collider and kinematic rigidbody on it? just manually add to the rotation and position in FixedUUpdate?

[topaz mortar]

why not just use the built-in physics system?

[naive pawn]

it wouldn't have a consistent linear velocity, maybe they're going for that

[lavish magnet]

that one

And at the same time, The text is a child of the barrel

So when i rotate the barrel, how should i go about keeping the text still?

[topaz mortar]

I think you can fix the text by freezing it's position?

[lavish magnet]

like i want it to move with the barrel but not rotate as the barrel does

shoould i just not have it as a child?

My text doesnt have a rigidbody

[topaz mortar]

yeah just figured lol

[naive pawn]

this is.. maybe convoluted, but here's an idea
have the root barrel object be just an rb that you move linearly, and the barrel model as a child (it should be a child anyways) animated or rotated to spin, and the text also as a child of the root

[lavish magnet]

I may try tht

ohhh sorry i didnt see that other user already mentioned that

my bad

[charred spoke]

You can have the text not be a child and use this https://docs.unity3d.com/Manual/class-ParentConstraint.html to only follow the position of the barrel. As for moving the barrel it depends on what you need. Need physics ? Just add a force to the dynamic rb. Dont need physics, then write a small script that moves and rotates it

[lusty star]

Is... is this the game from the ads?

[chrome apex]

so does my method where I save playerprefs need to be static in order to reference it in another script?

[lethal smelt]

Nop

[chrome apex]

so why doesn't GetString work for me? Says key doesn't exist

[lethal smelt]

just know that their values get reset after you build

[chrome apex]

that's good but it doesn't seem to work

[lethal smelt]

show script

[chrome apex]

private void Awake()
{
PlayerPrefs.GetString(levelsPassed);
}

that's all lol

do you want the saving script?

[lethal smelt]

its suppose to be PlayerPrefs.GetString("levelsPassed");

[chrome apex]

oh

it's always something stupid...

thanks, it works

[lethal smelt]

oh wait unless you alrady declared that as string before

that could work too

[chrome apex]

well I did

    if (newH < health) {
        Destroy(hbar[hbar.Length - 1]);
     }   
    }``` whats wrong w this code?

there are 5 triangles in the scene w tag "h"

i want to destroy one as the health decreases

should look like this

[sand gate]

alright

[chrome apex]

Winlevel.levelsPassed = PlayerPrefs.GetString("levelsComplete");

Is this how I'm supposed to get it when I open the game?

[rich ice]

may be better off using an array set in the inspector. FindGameObjectsWithTag wont give you a consistent order

[sand gate]

thats not my issue

no triangle is getting destroyed

[slender nymph]

a few things to note here:

1. do not use Find methods in Update, that is a recipe for bad performance
2. how can newH ever be less than health if you assign it to the value of health immediately after changing the value of health?

[sand gate]

OH

wow

alr

ill see

thankyou

how do i make it

update then

[fierce shuttle]

This could depend on when your trying to access your pref, it sounds like you might be trying to access a key that doesnt exist in prefs yet, though without seeing the full error, my suggestion would be to try checking if the key exists first, PlayerPrefs has a function for that: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/PlayerPrefs.HasKey.html - if you are stil having issues, post the full error message your getting and your full script with where you are calling your sets and gets, and im sure someone can provide more info for you

[slender nymph]

why not do the destruction of those other objects in the DrainHealth method?

[chrome apex]

already fixed

[sand gate]

i want to drain health everytime health gets reduced by 10

oh

i see what youre saying

let me try

[slender nymph]

please finish a thought before sending a message. we don't need you to spam a single thought across 5 different messages

[fierce shuttle]

Ah good to hear, though out of curiosity, what kind of data are you trying to save with PlayerPrefs? Is it just 1 or 2 simple values?

[sand gate]

if i use the FindGameObjectsWithTag method in Update() , will it keep refreshing the array every frame?

this is the error i am getting

[slender nymph]

why do you need to do that, just use a List that you populate in the inspector. then just remove the objects from the list when you destroy them. using any of the Find methods in update is terrible

[sand gate]

alright

[slender nymph]

show the stack trace for that exception

[sand gate]

how to do that 😞

[slender nymph]

https://unity.huh.how/stack-traces

[chrome apex]

literally 1 value for my entire game, "levelsComplete" so that if the user quits and returns another day, he can continue

it's webgl anyway so I think I can only use playerprefs for it

[rich ice]

click the error, show thing below

[sand gate]

Systems.collections.comparer.compare

[slender nymph]

huh? show the full stack trace

[sand gate]

i used Array.sort to sort , thats what was giving the error

the triangles are being destroyed, however the last one remaining isnt , ill work on it.

[slender nymph]

well if you do what i suggested instead of using Find then you won't need to sort the array

[astral falcon]

maybe show your code abot sorting. I guess, you are missing the actual sorting comparison

[sand gate]

i will try that , thankyou.

[sharp jolt]

Hi, I Can't find this where this error is, Unity is letting the game run and it runs perfectly fine so far no bugs or anything but i get this error about 200 times per second

[slender nymph]

You probably need to assign the root variable of the PlayerCharacter script in the inspector.

[sharp jolt]

Oh wait i swear that root variable didnt exist there before 😭

i was looking for it for so long

[astral falcon]

Finally you found eachother 🍀

[sharp jolt]

It was a long journey

[visual palm]

Does anyone know why I can't place the script on the inspector ?

[rich ice]

the script needs to be on an object

[polar acorn]

Because that script is not an instance of PlayerMovement, it's a text asset containing the code for PlayerMovement.

A blueprint of a house is not a house.

You need to drag in an object with the script on it. That object then becomes the PlayerMovement instance

[echo ruin]

The file you have open is called CollisionCheck, which just happens to contain a reference to PlayerMovement

[visual palm]

okay got it, thank you very much

[compact stag]

guys, i have this line of code, I wanted to make it so that the input field isnt empty, however, it always returns object reference not set to an instance of an object

    public void PlayGameStart() {
        if ( nameInput.text != null ) {            
            SceneManager.LoadScene(1);
        } else {
            
        }
    }

[slender nymph]

that means nameInput is null https://unity.huh.how/runtime-exceptions/nullreferenceexception

[polar acorn]

This one has that set, so this isn't the one throwing the error. Look at the other instances of this script

[compact stag]

DataManager is the only game object that has this script

[slender nymph]

how have you confirmed that

[polar acorn]

Go into play mode, get to when the error occurs, and search the hierarchy then

[compact stag]

i just made this script and havent applied it to anything else

[compact stag]

so this error happens when i play start

[slender nymph]

prove it by searching t:Singleton in the hierarchy while this error is appearing

[polar acorn]

So then search the hierarchy while you're in play mode after this error occurs

[compact stag]

oh, this was applied on the canva 🤦‍♂️

[slender nymph]

this is why you should always verify your assumptions

[compact stag]

i mustve applied it by mistake, im sorry guys

[compact stag]

that is fair indeed

i ran into another problem that the game still starts even if the input field is not empty but i want to fix this by myself

thank you guys!!

[slender nymph]

just note that a string can be empty without being null

[grand snow]

string.IsNullOrEmpty() can be used to easily check myStr != null && myStr != "" @compact stag

[compact stag]

i was about to say that!

im gonna use it

[slender nymph]

IsNullOrWhiteSpace is typically better

[compact stag]

how come?

[slender nymph]

because it checks if the string is only whitespace too

[grand snow]

depends on the source of the string. I would use Trim() any input and then check for empty state

[slender nymph]

string.IsNullOrEmpty(" "); is false
string.IsNullOrWhiteSpace(" "); is true

[slender nymph]

but why allocate unnecessarily when you can just check for it explicitly

better to Trim only after ensuring that the string isn't just empty, null, or whitespace. because you have to first ensure it isn't null before trimming anyway

[grand snow]

meh i dont think its bad unless we are working with some massive string

[slender nymph]

Sure it's not bad, and neither is calling GetComponent every frame, it's just not necessary to trim before ensuring there actually is any input

[compact stag]

    public void PlayGameStart() {
        if (!string.IsNullOrWhiteSpace(nameInput.text)) {            
            SceneManager.LoadScene(1);
            Debug.Log("true");
        } else {
            Debug.Log("false");
        }
    }
}

final code!

actually

I wanted to ask a question, its gonna be a bit hard to explain but

i have two scenes, the menu that has a gameobject called datamanager and the other one scene is called game

I have a text called User in the game scene, I made a public variable in my singleton script thats attached to my datamanager, however, how do I instantiate the user text in my singleton script?

should I use .Find? I heard its not the best way to do stuff

[burnt vapor]

It's not

I assume the user text is a UI component that you want to instantiate? I would just keep the UI ready without any extra instantiation if I were you

Keep references in a class close to the UI which holds the UI elements you want to access, then get a reference from that class so you can update the UI elements

This is an easy way to get everything together in one organized class and then you don't put it all in a manager that isn't just for UI

[compact stag]

yeah, the problem is, its in another scene

[burnt vapor]

You can use a Find method to get that UI class, but you can also just make that a singleton

[compact stag]

yeah, its already a singleton

is it okay to use .find in a singleton script?

[burnt vapor]

Find is messy because it's slow and prone to cause issues so you should not use it

[forest orbit]

why is my anchor thing missing?

[burnt vapor]

Why not just use a singleton?

[timber tide]

Is it on a canvas?

[forest orbit]

nope that fixed it ty

[twin pivot]

commenting one for loop out makes it work

but when i have both they dont work

[lethal smelt]

I wonder if it'll work if you replaced i with j for 2nd loop

[twin pivot]

tried that

did not work

[blissful mason]

That's because you're rotating it whatever degrees in one direction but then move the same amount in the opposite direction in the update call, which means nothing actually changed

[twin pivot]

no

its playing the for loop 40 times before it moves onto the next

[wintry quarry]

what are you trying to do here? This looks overcomplicated and yes the loop is actually pointless because it all happens in one frame

[wintry quarry]

It all happens within a single frame. it won't be visible

[twin pivot]

ah i see

im stupid

[blissful mason]

Yeah say it does it by 5 degrees, then it results in 200 degrees clockwise and then the next loop will do the same in the opposite direction

[wintry quarry]

you need a coroutine here or to just rotate once per frame in update and then reverse direction after a certain amount of time has elapsed or a certain number of degrees

[twin pivot]

alright thanks

hey guys. I wanted to know how to make trigger sensitive input in unity?

[twin pivot]

also i dont need anything else in this script

to run

[rich adder]

new Input System

[polar acorn]

Okay, so, you want the object to remain at exactly its current rotation?

[lament stag]

like will it register 0.5?

like for now it only takes 0 and 1

[twin pivot]

no

[wintry quarry]

more like something like this

float rotation;
float speed = 40;
float maxRotation = 40;

void Update() {
  rotation = Mathf.MoveTowards(rotation, target, speed * Time.deltaTime);
  transform.localEulerAngles = new(0, 0, rotation);

  // reverse direction
  if (Mathf.Abs(rotation, maxRotation) < 0.01f) {
    maxRotation = -maxRotation;
  }
}```

[rich adder]

actually maybe.
havent fully tried triggers yet there tbh.. you want a smoothed value?

[polar acorn]

But you just said you don't want anything else to run

that would include updating the object's rotation visually

So that would mean you want the rotations to perfectly cancel out and achieve nothing

[twin pivot]

ah i see

[lament stag]

yeah. Actually in a hackathon rn and they suggested me to add trigger sensitive things

[twin pivot]

thank you!

[rich adder]

new input system Unity has built, probably have more flexibility you can also configure your own Inputs / hardware

[polar acorn]

The Update function is one frame. It is the definition of what a frame is. The frame is rendered after every object's Updates finish running. Until an object's Update finishes, the frame cannot finish. You can never see the "intermediate state" of an Update.

[twin pivot]

ah i see

[polar acorn]

If you rotate an object 10 degrees left in update, then rotate it 10 degrees right in the same update, those both happen in the same frame

meaning nothing happens

[lament stag]

how can i configure my own inputs?

[twin pivot]

so the entire thing is happening in one frame

[wintry quarry]

as we have been saying yes

that's what update is

a single frame

[twin pivot]

and here is my ass thinking it was just hyperbole for "really fast"

[wintry quarry]

no it's literally "this runs once each frame"

[polar acorn]

That is, in fact, stated plainly on the default script template:

[twin pivot]

is there any way to go back to a certain line then?

[polar acorn]

no

Update is the frame

you cannot separate it across frames

It is the literal definition of what a frame is

[twin pivot]

no i mean

i take it out of update

but another way of looping it

[polar acorn]

#💻┃code-beginner message

[twin pivot]

i was asking how you did it

not what id need to do

[polar acorn]

With a coroutine, or one frame at a time by tracking time in update

[astral falcon]

Maybe you can rephrase,what you actually trying to do with going "back"

[swift crag]

A coroutine lets you write a method that can pause itself and get resumed later.

[twin pivot]

i dont know how to make a coroutine

[swift crag]

https://docs.unity3d.com/Manual/Coroutines.html

time to learn about them (:

[twin pivot]

yay......

[polar acorn]

https://docs.unity3d.com/6000.0/Documentation/Manual/coroutines.html

[twin pivot]

someone stab me

[swift crag]

if you hate learning new things, then you're in the wrong line of work

[twin pivot]

oh no i love learning new things

i love sarcasm a little more tho

[dusty nimbus]

Coroutines are easy and powerful once you start using them! ^

[rich adder]

they're ok. Not "powerful"

true power is pure async

[swift crag]

if you need to run a method across many frames, coroutines are great

[rich adder]

Awaitable has entered the chat *

[swift crag]

I pass Awaitables to StartCoroutine 😛

[rich adder]

I just hate that Coroutines cannot have return values for example

[twin pivot]

me and coroutine are gonna be great friends

[astral falcon]

Love them since Unity 6 🙂

Also the ability to jump back to mainthread

[rich adder]

yeah swapping threads is cool when dealing with unity main loop only API

[swift crag]

it's pretty nifty

I used Awaitable in one project to allow me to interleave game logic (e.g. moving a unit) with visuals (e.g. slowly moving the unit's sprite between the start and end positions)

[dusty nimbus]

Okay now I want to learn about awaitables - they sound a lot more useful than a coroutine 😆

[swift crag]

If I was just calculating a new game state (and not actually showing the sequence to the player), I skipped over the visuals and instantly returned

It worked out really nicely

[rich adder]

coroutines are fine for most usecase

but def do learn awaitable cause its great especially if you're stuck between coroutine and traditional async

unity has entry methods for both
IEnumerator Start()
async void Awake()

[polar acorn]

There's basically a power scale of delaying things,
Coroutines are like base form Goku, Awaitables are Super Saiyan, and async is Super Saiyan Blue. ||Invoke is Yamcha||

[astral falcon]

I based my entire state management on awaitables, calling other substates and so on. I did not even touch coroutines again since then 😄

[rich adder]

how do you deal with Get/Post methods ? do you not use WebRequests at all ?

the grabbing directly into assets is kinda handy ngl

I heard unity is strange with HTTPClient idk if it still applies

[astral falcon]

I use them with awaitables without any issue so far. Any special case why you askin?

[cosmic dagger]

I'd say Update is base form, and Coroutine is Kaio-ken . . .

[astral falcon]

So what would be InvokeRepeating be? 😄

[rich adder]

just curious , thats the only thing I haven't tried yet away from Coroutine, I'm so used to WebRequest. I never used anything else in unity since.
ofc in regular .net apps I use Async Task with dependency injected httpclient

[dusty nimbus]

So a Coroutine would use something like Wait X Seconds where an Awaitable is just like 'When I'm done I'll come back and we can carry on?'

[rich adder]

Awaitable can use the Regular Task.Delay
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Awaitable.WaitForSecondsAsync.html

[astral falcon]

old code but with awaitable, working just fine:

[twin pivot]

wait

[rich adder]

oh ok its still a unity webrequest just inside awaitable.

good enough 😄

[twin pivot]

can there be 2 yields in 1 coroutine

[rich adder]

you can have as many yeilds you want

[astral falcon]

yep 😄 Nothing fancy there

[wintry quarry]

as many as you want

[wintry quarry]

Don't start the coroutine in Update

that's crazy

start it in Start

[rich adder]

oh my..yeah starting one every frame not good lol

[astral falcon]

thats a lot of swinging going on tho, sounds like a good party 😄

[rich adder]

they will be fighting eachother setting values (dont ask me how I know)

you can also try close VS, regen project files

its working now

but only once

well i guess thats expected

it's doing exactly what your code is saying to do

rotate right

then rotate left

then it's over

like regular method it only runs once

[twin pivot]

yus

you can put a while loop inside

in coroutines they wont stop other lines from running

thats a very good question

and one that i dont have an answer to

[wintry quarry]

all you needed to do was wrap all the swinging() code in that while loop. Not add a random while loop to start

[twin pivot]

ah i see

YES

MY BUTTON IS NOW WIGGLING

[lethal smelt]

yk
what if you just make this animation with condition instead of all this code

[steep hollow]

how do i make an or in these onWall = Physics.CheckSphere(WallCheckLeft.position, WallDistance, Wallmask) || (WallCheckRight.position, WallDistance, Wallmask);

[twin pivot]

im making this to learn how to code so

[wintry quarry]

And is &&
Or is ||

but it's not clear what you're trying to do

[polar acorn]

You have to call the function twice

[rich adder]

why do you need an or ?
Just use the onWall ?

[twin pivot]

i dont know the normal way of doing this

[polar acorn]

you can't just or the parameters

[steep hollow]

iam trying to say if he's on the right wall or the left wall but it's giving me an error

[steep hollow]

ok

thx

[wintry quarry]

You would need two CheckSphere calls

and to OR the results of them

[swift crag]

I would just snap that line in half

bool leftWall = Physics.CheckSphere(WallCheckLeft.position, WallDistance, Wallmask);
bool rightWall = Physics.CheckSphere(WallCheckRight.position, WallDistance, Wallmask);

bool wall = leftWall || rightWall;

jinx

There's no reason it can't all go on one line

but it's too long. icky.

[wintry quarry]

only thing about this is it's actually slightly less performant because now we don't get the short-circuit benefits 😢

[swift crag]

true

[wintry quarry]

but that's a micro optimization 😛

[swift crag]

if only C# had lazily-evaluated expressions

[lethal smelt]

like python

[swift crag]

python does not have lazy evaluation

[polar acorn]

bool leftWall = Physics.CheckSphere(WallCheckLeft.position, WallDistance, Wallmask);
if (leftWall) return true;
bool rightWall = Physics.CheckSphere(WallCheckRight.position, WallDistance, Wallmask);
return rightWall;

[lethal smelt]

then what does

[swift crag]

Haskell delays evaluation until it's necessary, i believe

it's not super common (you usually have to do it explicitly, like by writing a zero-argument anonymous function that performs the calculation)

a "thunk"!

[steep hollow]

if it works it works

[strange tapir]

am i misunderstanding how "linear velocity" works?

    public void FixedUpdate()
    {
        Debug.Log(_body.linearVelocityY);

        // Bird rotation
        // Idk why unity does this
        _rotation = Mathf.MoveTowardsAngle(_rotation, _rotationAngle, _rotationSpeed);
        transform.rotation = Quaternion.Euler(0, 0, _rotation);

        if (_body.linearVelocity.y > _rotationSwitch)
        {
            _rotationAngle = _downwardAngle;
        }
    }

    public void OnJumpPressed(InputAction.CallbackContext context)
    {
        // Apply jump force
        // Only when the button is first pressed.
        if (context.started)
        {    
            _body.linearVelocityY = _jumpForce;
            _rotationAngle = _upwardAngle;
        }
    }```

i have this player script, and i was checking linear velocity... and it NEVER reaches 0? it keeps on going into the minuses

i thought since i have gravity pulling the player down at all times, itll reset when i jump, but it doesnt..

uhh this is my rigidbody setup

pretty sure its literally the default 😭

[polar acorn]

You should probably not depend on it ever reaching exactly 0, since there's always a chance it goes from positives to negatives within a single frame or vice-versa

[strange tapir]

im checking specifically if it reaches -0.7

but it ALWAYS is

[polar acorn]

Don't depend on it ever reaching any specific number

[strange tapir]

i see

i was just confused as to why its always so low

-8.81 shouldnt be possible to reach

[polar acorn]

Why not? That's only about a second of gravity

[strange tapir]

since the player is constantly jumping and the velocity should be set to 3.35

and IVE never seen it be set to 3.35

...oh my god im working in FixedUpdate()

the issue is that i was trying to do something when the player is FALLING (usually meaning negative velocity) but that doesnt seem to work

[twin pivot]

how do i add force in 2d?

oh basically same as 3d

[rocky canyon]

🙂‍↕️

[tropic agate]

does anyone know why my camera goes a bit up when I crouch then immediately sprint?
https://paste.mod.gg/kedoezrfxrih/0

[twin pivot]

is there a way to add force without having collisions

[wintry quarry]

If you don't want collisions, don't have a collider

forces are for the Rigidbody

[twin pivot]

ah

im reading the 2d rigid body article in unity

but i dont really understand it

[wintry quarry]

what don't you understand

[twin pivot]

i cant find an example prompt of it

[opal kernel]

hi, im starting to learn c# and is code monkey's tutorial good?

[wintry quarry]

I don't recommend code monkey

[twin pivot]

learn.unity.com

[wintry quarry]

he will teach you how to use and be dependent on his own libraries and such, not to learn C# and Unity in general

[opal kernel]

ok

rigidbody2D.AddForce(new Vector2(x force, y force), ForceMode2D.impulse/force);

[rocky canyon]

i would say imo hes more intermediate

[twin pivot]

this is basically it right

that's an AddForce call

that's how you add a force to the Rigidbody

ok

[twin pivot]

how would you rate vegetarian zombie

[rocky canyon]

watch the couple of episodes of this.. (or all of it if u want)

[opal kernel]

alr thanks

[rocky canyon]

whats ForceMode2D.impulse/force) ?

[cold mist]

its a pretty good playlist

[rocky canyon]

rb.AddForce(Vector2.up * forceAmount, ForceMode2D.Force); //gradual force

rb.AddForce(Vector2.up * forceAmount, ForceMode2D.Impulse); // Instant force

[twin pivot]

the two types of force isnt it?

yea

[rocky canyon]

rb.velocity = new Vector2(moveX, moveY) * moveSpeed; u can also set velocity

theres other modes too but impulse and force are the two i use most often

[rocky canyon]

its a great playlist..
nice simple..
straightforward..
no fluff or clickbait stuff..

it really helps break down the very first fundamentals u need to know

• variables
• methods
• classes
  and so on

[cold mist]

yeah, you recommended it to me too

watched all of it and it was pretty great

[rocky canyon]

alot of the other game-type videos are like:
"so u wanna make a game?"
"let me show u how to throw crap together that u dont understand in less than 15 minutes to make a game!"

you wont understand it but it'll work! 😄

[rocky canyon]

all of it?! very impressive..

all of it

did unity essentials too

that the other guy recommended

what does this mean?

[polar acorn]

You can't create a new variable with the same name as an old one

[lethal smelt]

you can't declared variable inside of condition (if)

You already have a variable of the same name outside the current scope . . .

thanks friend

[forest orbit]

how can I clone this asset and put it in the same folder?

[polar acorn]

What do you mean "same folder"?

[forest orbit]

the characters folder

[polar acorn]

You're not gonna be putting anything in any folder at runtime

[forest orbit]

oh

thought you could do that

how can I loop through the children of this object?

[cosmic dagger]

Sure, what have you tried or looked up?

[slender nymph]

you're better off just putting those objects into a list, but you could technically just foreach over the transform

[forest orbit]

its so over complicated for no reason jesus christ

[slender nymph]

it's really not

[forest orbit]

I wish I could just reference the object and do like foreach object in object:getchildren or something

[slender nymph]

since you're clearly ignoring everything that everyone is telling you and refusing to bother googling it, why are you even here?

[polar acorn]

It is, quite literally, even easier than that

The thing you wish it did instead is longer than the actual solution

[forest orbit]

did google it

perhaps im not smart enough for unity

[lethal smelt]

{
Something(child.gameObject)
}```
its litterly this easy

[slender nymph]

considering you think it is incredibly difficult to do this, i sincerely doubt you actually put any effort into reading the information returned by any google search

[forest orbit]

how do I get gameobject tho

[polar acorn]

usually by dragging it in

[forest orbit]

do I have to manually drag an object into the component every single time

[polar acorn]

or by running this code on the object you want to use

[polar acorn]

You'll need to tell it which object you want to loop over somehow

it can't just divine that knowledge from the Spirit Realm

you gotta tell it

[forest orbit]

yea thats where I misunderstood

would be simpler if you could just reference any object that is in the scene

like in some other engines

[lethal smelt]

you can

just use Find

[slender nymph]

then you should start by learning the absolute basics of how c# and unity work. there are beginner c# courses pinned in this channel and the pathways on the unity !learn site are a good next step after you understand the fundamentals of the language

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[polar acorn]

you can

by dragging it in

that's how that works

[forest orbit]

😔

[slender nymph]

learn the basics of c#

[polar acorn]

Neither Image or Canvas is a transform, and you can't just windmill slam a foreach loop in the middle of your class scope and expect it to work

[cosmic dagger]

A Canvas component is not a collection of objects . . .

[slender nymph]

also we went over this yesterday, you can't just have arbitrary code outside of a method

[forest orbit]

I have other ui elements inside of my canvas

[forest orbit]

I'm just trying to loop through the buttons I have inside my canvas

isnt transform just position and rotation related?

[peak holly]

srry needed the link

[slender nymph]

stop what you are doing and go learn the basics. #💻┃code-beginner message

[polar acorn]

Then why did you say you wanted to loop through child objects

That's a different thing

[forest orbit]

child being canvas, child objects being buttons

[polar acorn]

Button is not a GameObject. It's a component

[forest orbit]

parent* I mean

[cosmic dagger]

That doesn't matter. Your canvas—in the hierarchy—is just a GameObject with children, not a collection: array, list, etc . . .

[polar acorn]

Mabye you should see if there's a function that can get a specific set of components in an object's children

[forest orbit]

If I were to assign a button to a variable, I'd type public Button blabla; so I just assumed that the different objects like button and canvas were the type

[wintry quarry]

Those are the types, of the components

[wintry quarry]

The Transform component is what determines the parent/child relationships of GameObjects

[wanton epoch]

I could use someones help with this issue I am having when turning my game into a multiplayer one.

My game a is 3d virtual art gallery and I use 2 gameobjects to determine the players camera/orientation/etc. Basically they communicate with each other to al;low the player to turn and move and see everything. The problem, is that I am using photon to make my game multiplayer, and I need to turn my player into a prefab and the gameobjects can no longer have the right reference needed.

For example, my CameraHOlder using a gameobject in my avatar called CameraPosition, but I dont know how to put the reference needed since im turning my avatar into a prefab.

[wintry quarry]

1. assign it at runtime
   or
2. add the camera as part of the player prefab rig

note that you should really oinly have one camera anyway per client

So if you go with 2. you would destroy or disable any camera except the local player's

[wanton epoch]

for the second option, would it be alright to just put my cameraHolder as child of my avatar?

[wintry quarry]

I don't know how your camera holder works

if that will work or not

[forest orbit]

wdym that the transform component determines parent/child relationships, isnt it just the hierarchy that does that? here I have Slot and Slot (1) inside of CharacterSelection, CharacterSelection is a canvas and the slots are Images

[wintry quarry]

it's an option but you might have to have it deparent itself when it spawns

[wintry quarry]

The hierarchy is a visualization of the child/parent relationships that are defined by the Transform component

[wintry quarry]

Notice that if you look here: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Transform.html

Transform defines the .parent and .GetChild methods and properties

because the child/parent relationship is defined in the Transform

[wintry quarry]

CharacterSelection is a GameObejct which has a Canvas component attached to it.
Slot and Slot(1) are GameObjects that have Image components attached to them

[forest orbit]

I see

so if I wanted to loop through the children of CharacterSelection I'd have to use CharacterSelection.GetChild(index)

[slender nymph]

assuming CharacterSelection was a variable of type Transform then yes, that is one way to loop through the children of that object

[wintry quarry]

Assuming CharacterSelection is a reference variable that holds a reference to the Transform of that object.

[forest orbit]

trying to add this so I can drag it but everything just turns red

not even doing anything with it its just there

[polar acorn]

Because you've got nonsense in Start

And the compiler has just given up

[forest orbit]

it works fine when I remove that one line public Transform lalala

[polar acorn]

Yes, when you remove the broken line, there is no longer a broken line

[slender nymph]

#💻┃code-beginner message

[modest dust]

How do you expect to make a program if you have no idea whatsoever how to use the language required

None of this would be an issue if you spent some time on learning tha absolute basics

[forest orbit]

you said I have nonsense in start, that's why the one line turned red, I say nothing is red when I dont have the one line, you say everything is red even without it

[polar acorn]

Yes, when you remove the invalid line of C#, then all the red lines go away

Protip: This line is the problem

[forest orbit]

what im asking is why that line would cause a problem, because all I'm doing is declaring that variable??

[polar acorn]

You're attempting to declare a class variable inside a function

You cannot use access modifiers inside of a function

[slender nymph]

if you would bother learning how c# works you might have some understanding of why that was invalid

[eternal needle]

how did you decide it'd also be a good idea to do multiplayer..

[polar acorn]

oh sweet christmas it's multiplayer

[forest orbit]

not doing it of my own free will unfortunately

just have to do it

[eternal needle]

🤷‍♂️ you dont even have the fundamentals of c# down. How do you expect to do anything in unity, which uses c#

[polar acorn]

Perhaps if you spent as much time reading the documentation as you've spent wasting everyone's time on Discord you'd be done by now

[slender nymph]

or instead of lashing out and making a shitty attempt at insulting the people helping you like a whiny toddler, you could try learning the fundamentals

[forest orbit]

all I did was declaring a variable inside a function rather than inside the base class, not that big of a problem, I dont understand why you could just tell me that from the beginning

[polar acorn]

Do you know what public means or are you just slamming that in random places

[forest orbit]

I dont understand why you have to be so pretentious, I just declared it inside of a function which apparently doesnt work in c#, at least not when its a public variable, you couldve just told me that instead of displaying your superiority

[polar acorn]

At this point it's because you've spent zero effort trying to problem solve on your own and are expecting us to write it line by line

You've exceeded your patience quota for the day, but we have plenty of spite available

[forest orbit]

I'll let you get back to whatever you were doing then, I'm sorry if I'm having trouble figuring out the syntax

[chrome apex]

Why doesn't this work but only the first time around:

       if (int.Parse(name)>int.Parse(Winlevel.levelsPassed) + 1)
    {
        button.interactable = false;
    }

when I save it after completing a level into player prefs, it works

it gives me an error at the parse, which should be impossible

[polar acorn]

Try logging the values before the parse and see what the value is right before the error

[cosmic dagger]

Try using TryParse instead . . .

[slender nymph]

if you do not understand the syntax, then maybe take the advice that has been given to you half a dozen times now and go learn the fundamentals of the language because that includes learning the syntax

[wintry quarry]

Why would it be impossible? Time to use Debug.Log and see what you're trying to parse.

[chrome apex]

I get very strange results

for the second variable, it just says (object)

[polar acorn]

Then that would mean that the thing it's printing is , which is, in fact, not an integer

An empty string is not an int

[chrome apex]

ahhhh I know why it happens

cause it's getting the value from the playerprefs

so it doesn't work unless I save

i.e. pass a level first

so can I do if null, then value is 0?

[polar acorn]

You should consider TryParse instead

and if it fails to parse, set it to 0

[slender nymph]

why are you saving an integer as a string in PlayerPrefs?

[polar acorn]

You know what good call

[chrome apex]

so how do I reference a failed parse?

[chrome apex]

I named the levels as 1, 2, 3, etc

trying to figure out which ones are locked, which unlocked

when for example level 3 is passed, the levelspassed variable is set to 3

[slender nymph]

so again, why are you saving an integer as a string in PlayerPrefs

[chrome apex]

then for all the other levels, int parse, if higher than 3, disable button for the level

I am saving a string, what

[slender nymph]

you already have it as an int, and you have the option to store an int in PlayerPrefs

so why are you instead saving it as a string

[chrome apex]

I'm not, I'm doing this

            PlayerPrefs.SetString("levelsComplete", levelsPassed);
            }

[slender nymph]

right so you have an int that you could use, but choose to use a string instead

[chrome apex]

ah yeah ok you have a point

[cosmic dagger]

Why are you trying to parse a string name into an int???

[chrome apex]

I explained it above

[cosmic dagger]

Ok, don't mind me then . . .

[chrome apex]

ok so how do I handle that first load where there's nothing in the player prefs? Add a bool called hasData = false.

If !hasData, then levelspassed = 0
else load levelspassed fomr playerprefs.

I would flip the bool once the first level is completed.

Does that sound about right?

[polar acorn]

Just store the last level completed in an int

if it's 0, then you've beaten none

if it's 1, you've beaten 1

and so on

[chrome apex]

yeah I do that

but on awake the menu scene loads that variable from playerprefs

[polar acorn]

And yet you're storing it in a string

[chrome apex]

when I just start the game, it errors

because it's null

[slender nymph]

what is the error

[chrome apex]

I mean, not error, it's an empty key from playerprefs

I only save it when I pass the first level

[polar acorn]

So you know what can't be empty string? An int

[chrome apex]

Oh because it defaults to 0?

[slender nymph]

nor can int be null

[chrome apex]

that would work then

yes yes good solution

it being 0 by default works in my case

thanks

[polar acorn]

almost like that's precisely why we have been continually saying to use an int instead

[slender nymph]

even if there wasn't somehow a default, you can specify a default if the key does not exist

[chrome apex]

I know man, but when I complete a level, if I make it an int I still have to parse it because (name of level completed) = that int

still have to parse the name of the level into an int so it's the same amount of work

[polar acorn]

Or you could use the build index

[chrome apex]

not that I'm not listening to you guys, I'm just trying to use my brain too

[polar acorn]

And even then, no it isn't. You're literally parsing half as many values

[chrome apex]

I didn't think about that other thing

[polar acorn]

Parsing one object is less than parsing two objects

[slender nymph]

you could also design your systems to not rely on the scene name and instead use some object in the scene or its build index or something

[chrome apex]

yeah I know, I could also be a good programmer, but I'm not 😄

I'll listen to you and make the playerprefs var an int

[wanton epoch]

Has anyone had this issue before where, while using Photon, the person who creates the room can move around and turn their camera but anyone who joins the room is stuck in place and cant turn their camera?

[wintry quarry]

Very common problem with a variety of causes. #archived-networking

[slender nymph]

that is a single method, not a class. and not even where you are calling GetButtonDown

[wintry quarry]

no

fixedupdate would be bad

Input needs to be processed in Update

[honest haven]

yh its in update

[wintry quarry]

You seem to only be doing UpdateMenuStats in the first poart

not in the else

I'm assuming that's what modifies menuStatus?

oh nvm

[honest haven]

yh so menuState resets each time

[chrome apex]

it works now, thanks guys

[honest haven]

menuStatus

[wintry quarry]

you sure you don't have those reversed?

Do you mean on another button?

Using getbutton does it every frame and i get this

I am also using the old input manager

if that helps

yeah exactly
