You'll need to provide more detail.

[twin ibex]

ok

[static blaze]

do a nullcheck on the script that's accessing the enemy object

[twin ibex]

this error appears after i aded a enemy spawners
so when the player kill the first enemy the error appear and the Spawnerrs didint work

[static blaze]

Well then you should probably put a prefab in the spawner instead of the enemy itself?

[twin ibex]

How exactly?

[twin ibex]

yes

the enemy is prefab

[static blaze]

Anyhow, sharing the code will always get you better help

im just guessing in the dark now

[twin ibex]

thats right

[twin ibex]

.

[twin ibex]

do u know how to bring back the enemy from the prefab

some help (;

[ivory bobcat]

Maybe show some code?

[twin ibex]

can u pleas just tell me how to bring back the enemy from the prefab

[ivory bobcat]

We don't know anything about your code or scene.

[twin ibex]

can u pleas just tell me how to bring back the enemy from prefab to a normal OBJ

(:

[ivory bobcat]

What have you tried?
Bring the enemy back from where?
This is the coding channel so I'm assuming we're discussing something about code.
#854851968446365696

[twin ibex]

@ivory bobcat
no i mean

the enemy is prefab now ok

do u understand me ?(:

[ivory bobcat]

Usually, you'd show what you've tried and people would give you suggestions.

[twin ibex]

see

[ivory bobcat]

.

[twin ibex]

are u joking ?
or troling

i wasted 1H

for this error

[uncut shoal]

?

[uncut shoal]

no they are asking you to show your code, they can't help you if you don't show your code.

[twin ibex]

the error not in the CODE

[uncut shoal]

it is in the code.

The error you sent can only be caused by a problem in your code.

[cosmic dagger]

if the error is not in the code then why are you asking in a coding channel?

[toxic void]

x = (gameObject.transform.position.x < 0)? gameObject.transform.position.x -0.5 : gameObject.transform.position.x + 0.5;

how can I type cast this into a float?

like how do you use type casting with the ?: operator

[cosmic dagger]

you don't need to cast anything, just use a float value for the amount you want to add . . .

do you know how to make a float value? if not, i'd look it up, it's quite simple . . .

[toxic void]

but I need to return it as a vector

oh wait nvm

I was missing suffix

I forgot

[cosmic dagger]

huh? you just asked about a float value, not it's supposed to be a Vector3? you're only assigning the value to x which i assume is a float . . .

[cosmic dagger]

yep . . .

[toxic void]

ye ye im stupid

[vague socket]

Hello, I'm fairly new to unity and I've just designed an enemy that detects if the player is in range and starts exploding once it's detected a player.

The enemy object currently has a polygon collider for it's hit box and a circle collider set to is trigger for detecting the player.

The problem I'm facing currently is that when circle collider is acting as a hit box as well. I read online that I should move the circle collider to an empty child object. My question is do I need to write a separate script for the child object or is there a way for the parent object to read the ontriggerenter of the child object.

Sorry if this is confusing and long 💀

[polar acorn]

All colliders will become "part" of their nearest parent rigidbody. If a rigidbody object has a box collider, and a child object of that has a circle collider, an OnCollisionEnter script on the parent will fire if something hits the circle collider.

When a collision happens, the rigidbody component is the thing that calls the OnCollision functions, and it calls it on itself and the attached rigidbody of the collider it's interacting with (if it has one)

[languid spire]

Absolutely not, A script can have both OnCollision methods and OnTrigger methods

[vague socket]

Thank you for your replies :).

[summer stump]

Just wanna say, this is a very common code error. It is saying the CODE is trying to use the object after it has been destroyed (which can only happen through code or I guess if you manually delete the object from the scene view during runtime, which you should of course never do)....

[languid spire]

The error is most definitely caused by your code but as you wont share it there is no helping you

[wispy bison]

Hi guys, i have bought a pack named Low Poly Restaurant, did you know why i see all like this_

[polar acorn]

Incompatible render pipeline. Your project is using a render pipeline your materials aren't compatible with.

[wispy bison]

So how i can fix?

[polar acorn]

Use materials compatible with your render pipeline, or use a render pipeline compatible with your materials.

One of em has to change

[wispy bison]

Fixxed thank you

[tacit river]

private void OnCollisionEnter(Collision collision)
    {
        placement.CanPlace = false;
    }``` this is not doing anything when a collision happens, did i code it wrong?

[polar acorn]

The Three Commandments of OnCollisionEnter:

1. Thou Shalt have a 3D Collider on each object
2. Thou Shalt Not tick isTrigger on either
3. Thou Shalt have a 3D Rigidbody on at least one of them

Hi! Im a beginner and have some trouble with my start screen and buttons. I did an animation for the start screen and make the button to play the game but its not clickable?

When i try to click on the button the game screen closes

[calm chasm]

I'm having issues with an instantiated object not running its Start() and therefore getting NullReferenceExceptions later on in the same script (many many frames after the initial instantiation). I've read in multiple forums that Start() will always run for instantiated objects, so I'm a little confused here. Any clue on what might be happening? I can provide more info if needed

[gaunt ice]

Start will run before the first Update this object exists and is active for

[gaunt ice]

is the prefab is disabled by default, the start wont run iirc

[calm chasm]

Instantiation code on the player object

    //The class this is running on is not a child of Monobehaviour, it's just a standard C# class with a method named Start
    public PenFeatherShotBehaviour() : base()
    {
        actionBuffer = new Timer(0.05f);
        // PREFAB LOADING
        featherShotPrefab = Resources.Load<GameObject>("Entities/Player/FeatherShot/FeatherShot");
        emberCost = 0.5f;
    }

    public override void Start()
    {
        base.Start();

        pen.animator.SetTrigger("shoot");

        pen.SpendEmber(emberCost);
        // INSTANTIATION
        GameObject featherShot = GameObject.Instantiate(featherShotPrefab, pen.transform.position, Quaternion.identity, pen.transform.parent);
        Movement2D featherMovement = featherShot.GetComponent<Movement2D>();
        featherMovement.velocity = new Vector3(FeatherShotController.baseSpeed * pen.facing, 0, 0);
    }

** Start() of the parent of the parent class of FeatherShot (the prefab who's Start() is seemingly not running)**
The child classes all have a base.Start() on their own Start().

    public virtual void Start()
    {
        attachedHook = null;
        //VVV^BREAKPOINT HERE DOES NOT RUN WHEN FEATHERSHOT IS INSTANTIATED!! VVV
        Transform hurtboxTransform = transform.Find("Collision/Hurtbox");
        //^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

        // [More irrelevant code here that is never being run]

        //This variable is not being initialized on FeatherShot
        immunityTimers = new List<(Timer, Immunity)>();
        stuckTo = false;
    }

[calm chasm]

prefab is enabled by default

[calm chasm]

Breakpoint in the very first line of Start() is never being triggered for this object

I understand that's how it's meant to work but clearly I'm doing something wrong 🤣

Wait, actually, might have spotted it

[cosmic dagger]

are you calling Start anywhere?

[gaunt ice]

who calls start? this is no monobehaviour

[cosmic dagger]

if the parent class is not a MonoBehaviour, you need to call it, Start, manually . . .

[calm chasm]

yes, another class is calling start, otherwise the object would not have been instantiated in the first place :P

regardless it seems I've spotted the issue, and the breakpoint was working after all

I'll pick it up from there, thanks!!

[cosmic dagger]

show us where. instantiation is separate from a method being called on the instantiated object . . .

[gaunt ice]

i think you should share the code on featherShot(?) indeed, you say the NRE happens in that script not the instantiate script

[calm chasm]

The issue was completely different from what I though; Start is running after all, it's just seemingly stopping the method in a GetComponentsInChildren halfway through the full Start() method. I'll dig a lil deeper into it before bugging you guys again :)

[gaunt ice]

maybe the getcomponentsinchildren throws exception cause the start method is not "fully" executed

[calm chasm]

The GetComponentsInChildren is within the Start that's not fully executing, so anything it needs to run is already initialized by then
Is there a way for me to see exceptions being thrown by a specific line while step-by-step debugging? My log is being flooded by the aforementioned NRE

 public virtual void Start()
    {
        attachedHook = null;

        Transform hurtboxTransform = transform.Find("Collision/Hurtbox");
        if (hurtboxTransform != null)
        {
            hurtbox = hurtboxTransform.GetComponent<Rigidbody2D>();
        }
        else
        {
            hurtbox = null;
        }

        boundsExtents = Vector3.zero;
        boundsOffset = Vector3.zero;
        
        Collider2D[] colliders = hurtboxTransform.GetComponentsInChildren<Collider2D>();
  // STOPPING HERE
        if (colliders.Length > 0)
        {
            Bounds bounds = new Bounds();
            bounds.center = (Vector3)colliders[0].offset + transform.position;
            bounds.Encapsulate(colliders[0].bounds);

            for (int i = 1; i < colliders.Length; i++)
            {
                bounds.Encapsulate(colliders[i].bounds);
            }
            boundsExtents = bounds.extents;
            boundsOffset = bounds.center - transform.position;
        }

        immunities = new List<Immunity>();
        immunityTimers = new List<(Timer, Immunity)>();
        stuckTo = false;
    }

[gaunt ice]

i remember there is a error pause button on console, turn on it

the hurtboxtf maybe null and you call a getXXX method on it

[cosmic dagger]

is hurtBoxTransform assigned?

[calm chasm]

That's it, I forgot to add my hurtbox to the dang projectile

Tyvm

[gaunt ice]

he uses find to find that tf

[cosmic dagger]

if it's null, hurtbox will not be asigned and execution continues and tries to access it on the line before it stops . . .

when ever you get an NRE, look at the all the reference variables on the line and check they have a value (are assigned) . . .

[cosmic dagger]

yeah but there's no edge case for when it's not found bc they still try to access it later . . .

[cosmic dagger]

also, if you're dragging it from the inspector, when you attempt to find it in code it will overwrite the value . . .

[calm chasm]

I'm using all the finds to avoid drag and drop

I just forgot that some objects will not have hurtboxes, such as this projectile, and needed to add additional checks for that

[polar acorn]

If you can drag and drop, you should drag and drop. Find is slow, and you can't get any faster than free

[cosmic dagger]

i'd do the opposite. Find methods are slow while drag n' drop is the most performant since it involves no coding . . .

[gaunt ice]

try to not use find, drag and drop can guarantee the component is assigned

[calm chasm]

I see, I see. I'll get to refactoring that, since there's few objects to change, then

[cosmic dagger]

you can have a check to assign a value if it is null (meaning it wasn't assigned a value from the inspector . . .

[gaunt ice]

btw it will throw an unassigned exception if you have not assign it

[river glade]

Hi everyone, I'm trying to give a smooth movement to a drawer, could you give me a tip?

https://pastebin.com/E5TBKhf6

[cosmic dagger]

try saving the file as C# so there is syntax highlighting. helps to read the code . . .

[river glade]

done

sorry, my mistake

[cosmic dagger]

not a problem, just helps to see what is going on easier . . .

[river glade]

yes , ty

[cosmic dagger]

Lerp is used incorrectly. when using Lerp is good to use a duration. to animate linearly. you can also use MoveTowards, i think they have a Vector3 option . . .

[river glade]

should I use a target in the " endPosition " position?

[cosmic dagger]

the end position is your destination . . .

the third value for Lerp, *t*, should be animated from 0-1, typically, determined by the elapsedTime/duration. elapsedTime is added to every frame . . .

[languid spire]

also, the yield is outside of the while so the Lerp is moot

[cosmic dagger]

yep, and the !open doesn't Lerp at all, it just sets the position . . .

[languid spire]

and it's an infinite loop

[river glade]

basically everything was wrong lol

[languid spire]

yes

[summer stump]

And there is a bit too much whitespace

Sorry, just teasing.

[cosmic dagger]

but it's a work in progres, so . . .

i wanted to speak on the whitespace but declined myself . . .

[river glade]

the white space is due to the fact that I deleted a lot of things and quickly copied and pasted them into pastebin, it's still a work in progress ahah

[languid spire]

Hey, he can have as much whitespace as he wants, it will neither generate a compile nor runtime error

That is the least of his worries

[cosmic dagger]

true, i just hate scrolling . . .

that's a me problem though . . .

[river glade]

I'm simply learning programming, peace and love haha

[cosmic dagger]

what do you have now, so far?

[languid spire]

you and me both, thats why I use a big portrait monitor for coding

[summer stump]

I was just teasin, no need to worry about that at all, like steve said

[river glade]

I'm almost done with my project, I'm missing the last few things, it's not a triple A obviously, but I'm satisfied with my work

[cosmic dagger]

see, i did that, but turned it back bc i end up watching a bunch of stuff on it. it's hard to dedicate the entire monitor just for that — then again, sadly, it's not my day job (which would make more sense, or maybe i'm not decicated enough 😔) . . .

[cosmic dagger]

hey, better than most of us sticklers . . .

[languid spire]

I run 6 monitors, dedicating 1 to coding is not a problem

[cosmic dagger]

jeezus! i have no excuse though, since i have 3 myself. are you using 1 for each asset you work on, haha . . .

[river glade]

lol let's say that programming has kept me out of trouble, I live in a dangerous suburb, so programming has been my salvation, I didn't have a good childhood, I'm making up for it

[river glade]

omg , i love it

[cosmic dagger]

making the best of it, good thinking . . .

[river glade]

exactly and since I don't even have a house and I'm supported by someone, I use my free time to learn programming

[languid spire]

From left to right
Windows Operating System
Unity game View
Visual Studio
Unity Editor
Web browser
MacOS VM

[cosmic dagger]

oh, that's like a dedicated unity layout, nice!

[languid spire]

Works for me

[cosmic dagger]

i think 3 across: landscape, landscape, portrait, with a 4th above the middle would work perfect for me. i'd need a different monitor arm though . . .

[languid spire]

tbh I tried multiple vertical monitors, didn't like it, neck strain, horizontal works better imo

plus the mouse movement is really weird using multiple verticals

[cosmic dagger]

especially, if you sit close to the desk . . .

[queen adder]

When i create a variable that has a type of "System.Action", the compiler tells me to convert that into a local function like this:

public void Method()
{
  System.Action variable = () => cute();
  // After i listen to the compiler:
  void variable() 
  {
     cute();
  }
}

Which one is more efficient way for Garbage and performance

[woeful hedge]

What should I do to execute Multiple gameObjects Component's function which have same name?
Like BroadcastMessage() but can use outer Gameobject and its child.

yep I could just grab them to large List<> but I dont want em

[swift crag]

I would just make explicitly make a list once and then use that list every time i need to call the methods

[polar acorn]

So, you want to call a specific function on a collection of things that all have that function?

[cosmic dagger]

i'd use an event/delegate . . .

[woeful hedge]

I want to call a function which has the same "name" inside all GameObject's Components
like

// in GameObject A
{
I_call_every_func_which_has_same_name("Print", gameObject.name)
}

// in GameObject B
void Print(string gname)
{
  debug.Log("Print Requested by " + gname)
}

[polar acorn]

Event

I hate you dyno

Anyways Thanks for answer :)

[twin ibex]

Hi
i have a problem with the Enemy in the game
When the Player kill the Enemy the console shows a error
THe error 👇

Your script should either check if it is null or you should not destroy the object.```

[polar acorn]

Something is still referencing the object that is destroyed

[twin ibex]

so What's the solution ?

[twin ibex]

ok and what should i do

[polar acorn]

Stop trying to reference an object that is destroyed

This is really all that can be answered with no context

Somewhere you're referencing something that no longer exists, stop doing that

[twin ibex]

i know but ..

[twin ibex]

its the Ennemy Spawner

[polar acorn]

Okay, so your enemy spawner should probably not hang on to references of destroyed enemies

[twin ibex]

how ?

[polar acorn]

¯_(ツ)_/¯

I have no idea what your system looks like

I don't know what reference is being destroyed

[twin ibex]

i will show u

[twin ibex]

if u see the code can u tell me the solution ? ^_^

[polar acorn]

It'd be easier to find a code problem if you posted the code yes

[zealous oxide]

evening friends. i've got a transform in here on an enemy spawner but the transform doesnt update, despite the object that was dragged into the field having moved (its always to the right, relative to the player). is there some way i can force update the transform

[polar acorn]

That will reference the specific transforms of the objects you drag in. If those objects move, their new values will be reflected in their transform that you are currently referencing

[twin ibex]

using System.Collections.Generic;
using UnityEngine;

public class SpownSystem : MonoBehaviour
{
    public Transform[] spawnPoints;
    public GameObject Enemy;
    int randomSpawnPoint;

    void Start()
    {
        InvokeRepeating("SpawnEnemy", 0, 1.5f);
    }

    void SpawnEnemy()
    {
        randomSpawnPoint = Random.Range(0, spawnPoints.Length);
        Instantiate(Enemy, spawnPoints[randomSpawnPoint].position, Quaternion.identity);
    }
}

[polar acorn]

Is Enemy a prefab or an object in the scene

[twin ibex]

first i try to make the enemy a prefab but the error is keeps appearing

now its not prefab

but nothing changes

[polar acorn]

So when that specific enemy is destroyed what are you attempting to clone

[twin ibex]

the enemy itself

[polar acorn]

But it's destroyed

[twin ibex]

the spawner cant make more clone

[languid spire]

show the code that is doing the Destroy

[twin ibex]

i know

[polar acorn]

So why are you spawning an object that can be destroyed, instead of a prefab

[twin ibex]

so i need to make the enemy a prefab??

[polar acorn]

Yes

[twin ibex]

private void OnCollisionEnter2D(Collision2D collision)
    { 
        if (collision.gameObject.CompareTag("Bullet"))
        {
            Instantiate(Explosion, transform.position, Quaternion.identity);
            Destroy(collision.gameObject);
            Destroy(gameObject);
        }
    }
}```

[twin ibex]

but its keeps apearing

??

[polar acorn]

what keeps appearing

[twin ibex]

This error

Your script should either check if it is null or you should not destroy the object.```

[zealous oxide]

I understand that bit, so the object thats dragged in is a "platform spawn checker", essentially its a dummy object with no function bar a script so it always stays on the right side of the player at a specific distance, however when the wavespawner script instantiates enemies, it doesnt instantiate them at the current position of the "platform spawn checker"

[polar acorn]

Show code

[polar acorn]

Did you actually use the prefab or did you just make Enemy into one

[twin ibex]

seee
the enemy is prefab

[polar acorn]

You have to drag in the prefab into the spawner's variable

[twin ibex]

yes?

[polar acorn]

Show the inspector for the enemy spawner

[twin ibex]

the spawnPoints is the enemySpawner

[polar acorn]

Okay, so, Enemy is a prefab. That means the error can't be coming from Enemy being destroyed

[twin ibex]

?

[polar acorn]

The error isn't coming from Enemy being destroyed. It's somewhere else.

[twin ibex]

from where

[twin ibex]

but the error apears when the enemy got destroyed

[languid spire]

show the COMPLETE error

[twin ibex]

ok

[polar acorn]

Then it's possible a different thing is referencing the destroyed enemy

[twin ibex]

MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.

[cosmic dagger]

still the same error . . .

[twin ibex]

how?

[zealous oxide]

https://hastebin.com/share/vijenevowo.csharp here you go 🙂

[polar acorn]

Which line is line 19

[rich adder]

doesnt this mean they referenced a destroyed object they added in the inspector and trying to spawn it

[polar acorn]

Yes, but I've been assured it's referencing a prefab and not a scene object

[twin ibex]

where is 19 theris only 6 lines

[languid spire]

I wonder if it is a spawnPoimt which has been destoyed

[polar acorn]

Then you haven't saved

Because the line numbers don't lie

[twin ibex]

so should i delet the enemy from the inspector

[twin ibex]

??

[rich adder]

ah ok so they showed it was a preab from project folder?

[polar acorn]

They've shown they have a prefab and have said that's what they dragged in, so ¯_(ツ)_/¯

[twin ibex]

19 from error or code ???@polar acorn

[polar acorn]

From the script

[twin ibex]

oh

what code the spawner code?

[rich adder]

SpownSystem prob

[polar acorn]

Right after spawning the enemy, put this line, then show what the logs say:

Debug.Log($"Spawning an enemy at the position of {spawnLocation[spawnIndex]}, which is {spawnLocation[spawnIndex].position}. Enemy is at {enemy.location}",spawnLocation[spawnIndex]);

[polar acorn]

So, it's possible that an element of spawnPoints was destroyed. Are any of them ever destroyed?

But let's first make sure. Can you show a screenshot of the thing you dragged into the Enemy variable on this script

What was the thing you clicked on and dragged into the slot

[chrome scarab]

Hello, in this following code:

    void OnTriggerEnter2D(Collider2D collision)
    {
        if (isAttacking || isAttacked)
        {
            if (collision.CompareTag("Enemy"))
            {
                damage = 10f;
                enemyHealth = collision.GetComponent<EnemyHealth>();
                enemyHealth.DamageEnemy(damage);

                if (enemyHealth.enemyHealth <= 0f)
                {
                    Animator enemyAnimator = collision.gameObject.GetComponentInChildren<Animator>();
                    enemyAnimator.SetBool("Die", true);
                    //wait
                    Destroy(collision.gameObject);
                    killedEnemies += 1;
                }
            }
        }
    }

I want to add something to the //wait section that will make it wait for 1.5f seconds. How can I do this? The reason I want this is to wait for the death animation to end instead of destroying the gameobject instantly.

[polar acorn]

Destroy takes in a delay parameter

[wintry quarry]

You need to make this a coroutine then you can do that

[polar acorn]

You can just have the destroy happen after some amount of time

[rich adder]

use animation event

[twin ibex]

see

[wintry quarry]

Or these ^

[chrome scarab]

oh float t?

[polar acorn]

Yes

[chrome scarab]

oh tyvm

[zealous oxide]

Right after spawning the enemy put this

[chrome scarab]

Why does it tell me to remove it when I get to this line? it was doing this a while ago, I don't understand why...

[twin ibex]

@polar acorn

[polar acorn]

Which thing did you drag in. This is very important

[twin ibex]

in what

[chrome scarab]

When I deleted it and did ctrl z it was fixed. bruh...

[rich adder]

intellicode having a brain fart

[polar acorn]

Which thing did you drag into the Enemy slot on the spawner

[chrome scarab]

bruh. So all I have to do is ctrl z?

[twin ibex]

i dont understand exaxtly

[polar acorn]

How did you set Enemy on the enemy spawner

[ivory bobcat]

Escape?

[rich adder]

just ignore it what its telling you ..sometimes it doesnt know wat you want to do. You probably have Destroy() without second paramater so it got confused

[twin ibex]

i drag it simply

[chrome scarab]

It didn't work. But anyway, it's fixed now.

[polar acorn]

What did you drag in

What thing did you click your mouse on and then move to the slot

[twin ibex]

the enemy

ohhhh

[polar acorn]

which

fucking

one

[twin ibex]

the left click

[chrome scarab]

he says this is a prefab or gameobject or transfrom or what?

[polar acorn]

Show me the thing that you dragged in

I'm not going to ask again

what thing

did you click on

to drag

into the slot

[languid spire]

before you answer, there are 2 enemies on the screenshot you sent

[twin ibex]

can i send a vedeo

[polar acorn]

sure

just show me

which Enemy

you drag in

[chrome scarab]

He asks what you put there. 1 or 2?

[twin ibex]

oh

im dumb

the num 1

[rich adder]

oof

[chrome scarab]

it's a gameobject

[polar acorn]

I asked you multiple times if you dragged in the prefab or the enemy in the scene

and every time

you said the prefab

[chrome scarab]

bruh

[rich adder]

yeah as soon as you hit play Prefab turns into GameObject

[twin ibex]

i didnt know thers defrent

[rich adder]

the one in the Project folder is the blueprint you need

[summer stump]

One is an asset you can reuse easily, the other is an single instance of an object

[chrome scarab]

If you put a gameobject in that slot, you will get an error when that gameobject is destroyed or disabled.

[twin ibex]

thanx for this ('

[chrome scarab]

u re velcome

[twin ibex]

@polar acorn
im SO VERY EXTREMELY SORRYfor my stupidity

[chrome scarab]

I had the same problem with someone else, I think it was the same person XD

Which children does this get the tilemap component from?

tilemap = grid.GetComponentInChildren<Tilemap>();

[chrome scarab]

I want it to get this tilemap from "Zemin".

[willow scroll]

assuming that grid and its other children don't have Tilemap component too

[chrome scarab]

Of course, others also have tilemap, I wouldn't ask if they didn't have it xd

[willow scroll]

otherwise you have to Find or FindGameObjectWithTag

[chrome scarab]

        foreach (Tilemap tilemap1 in grid.GetComponentsInChildren<Tilemap>())
        {
            if (tilemap1.name == "Zemin")
            {
                tilemap = grid.GetComponentInChildren<Tilemap>();
            }
        }

This was the first solution that came to my mind. but I didn't test it.

[willow scroll]

of course? then it's gonna get tilemap from Duvar

[chrome scarab]

So it takes from the first object. I understand.

[rich adder]

why dont u just put fields in the inspector?

GetComponentInChildren find the First component

[chrome scarab]

So does this work? Or is it a bad solution?

[rich adder]

what is this point of doing this..

[willow scroll]

grid.GetComponentsInChildren<Tilemap>().First(w => w.name == "Zemin");

[rich adder]

just un-necessary calls to GetComponent tbh

[willow scroll]

it won't work

you assing tilemap to new GetComponentInChildren

you have to assign it to tilemap1 to make it work

[rich adder]

tilemap1 is the var for the loop

you cant change it during a foreach loop

[chrome scarab]

like that?

[cosmic dagger]

that is local variable in the foreach loop . . .

[rich adder]

why are you doing this instead of just using a field 🤔

[willow scroll]

what do you mean?

foreach (Tilemap tilemap1 in grid.GetComponentsInChildren<Tilemap>())
{
    if (tilemap1.name == "Zemin")
    {
        tilemap = tilemap1;
    }
}

[chrome scarab]

how so?

[rich adder]

uhh the same way you did Grid

like an inspector field i meant

[willow scroll]

they mean you can serialize it and assign it in the inspector

[rich adder]

nah thought you meant changing tilemap1

[willow scroll]

it's impossible.

[rich adder]

I know I said that

[chrome scarab]

The reason I do this is because I need to select a tilemap in another script. and I need to select gameobject to select the tilemap. And when I select gameobject, I cannot apply to prefab.

[willow scroll]

but "assign it to tilemap1" means that you have to set smth to be equal to tilemap1, no?

[rich adder]

you could just pass it when you spawn the prefab

[rich adder]

idk I got confused by the wording

you have to assign it to tilemap1

no biggie 🤷

[chrome scarab]

Will it not give an error when I move from one scene to another in the game and come back to this scene?

[willow scroll]

I think my English sentence structure still wishes the best

[rich adder]

the reference gets losts between scenes unless you persist them, otherwise why would the same object be in the scene? they also get destroyed

[olive wharf]

I'm tryna recreate the circle illusion where the dots move in a straight line but it looks like a circle rolling. I've got it mostly down but I have an issue with how my dots are placed about; they make gaps instead of being evenly spread in a circle looking way:

using System.Collections.Generic;
using UnityEngine;

public class DotsManager : MonoBehaviour
{
    public GameObject dotPrefab;
    public List<GameObject> dots = new List<GameObject>();
    public int dotAmount;
    public float dotSpeed;
    public bool showLines;

    float angle;
    float turningAngle;

    void Start()
    {
        turningAngle = 0;
        dotAmount = dots.Count;
    }

    void FixedUpdate()
    {
        angle = 0;
        turningAngle += dotSpeed;

        for(int i = 0; i < dotAmount; i++)
        {
            dots[i].transform.position = new Vector2((Mathf.Cos(angle) * 3f) * (Mathf.Cos(turningAngle + angle)), (Mathf.Sin(angle) * 3f) * (Mathf.Cos(turningAngle + angle)));
            angle += (180 / dotAmount);
            print(angle);
        }
    }
}

If it helps, I have a scratch project that does this that I'm using as referenece https://scratch.mit.edu/projects/809102399/editor/

Can anyone figure out what I have done wrong

[jovial peak]

question, so im making an editor and implementing an undo redo function, how do i get the prefab used to create the object before it is deleted, so it can be undone?

[rich adder]

look into command pattern probably

[languid spire]

RecordObject

[wintry quarry]

this? https://docs.unity3d.com/ScriptReference/PrefabUtility.GetCorrespondingObjectFromSource.html

[jovial peak]

thx ill have a look,

[chrome scarab]

Is there an easy way to find places where changes have been made? I've been browsing the inspector panel for 5 minutes...

[wintry quarry]

git status

[queen adder]

if you press on override in the inspector it will show you where u got changes

Overrides* tab when u click prefab in the inspector

[chrome scarab]

where is the difference i dont understand xd

enemy list is the same too

[wintry quarry]

When you click the apply drop-down should show a list

[chrome scarab]

no it's not

[queen adder]

Yeah some stuff does appear each time, i just memorize what is there, i usually get network object as the "change" i think its because it gets active or something im not completely sure why honestly

[queen adder]

yeah he is doing that but if u click on each of those stuff on list u get the differences

oh i get change for a reason though so forget it, never really checked on that haha

[chrome scarab]

Okay, I noticed it when I clicked on Human Transform. Somehow it has changed from prefab to gameobject...

[queen adder]

probably u got private values changed or other things inside of ur script

[queen adder]

if its in runtime its gameobject

[queen adder]

but also if ur Human Transform is inside of the prefab, it doesnt make it the prefab

now ur Human is a prefab though so forget this but if ur human has a gun within his hierarchy, the gun is not necessarily a prefab, and if u run the game its all gameobjects

[dusk minnow]

[languid spire]

use Color32

[dusk minnow]

https://paste.ofcode.org/3aMaP64h2aaydvTJ9H7fXLr

there is a list with colors and the tower laser (linerenderer) should first be the color of the list[0]

[rocky canyon]

colors use 0 - 1

[dusk minnow]

so 256 would be 0.0036565 something

or should i do 1/256

[rocky canyon]

theres a method to convert it directly

[languid spire]

just use Color32

[rocky canyon]

no need to figure out the math urself

Anyone knows how can i hide <summary> tags in vs code? they look so ugly

[terse solstice]

how can I give the illusion of walking by moving the first person camera

?

[dusk minnow]

i have reloaded a scene and all things got deleted how can i redo this

[polar acorn]

Do you have your old scene file

[thin kiln]

I'd like to double check that you know what they do and why the exist before proceeding.

[dusk minnow]

i did not see it in temp folder

[polar acorn]

Then you've overwritten it. If you don't have backups or version control, it's probably gone

[thin kiln]

You want to make sure that you're not in play mode when making changes to anything in Unity.
The behaviour is super finicky depending on the type of asset you're changing, but general rule is that you don't modify while in play-mode

[final kestrel]

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using TMPro;
using UnityEngine.EventSystems;

public class TextMaterialChange : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler
{

    [SerializeField] private Material hoverMaterial;
    [SerializeField] private Material originalMaterial;
    private TextMeshProUGUI textMeshPro;
    // Start is called before the first frame update
    void Start()
    {
        textMeshPro = GetComponent<TextMeshProUGUI>();

        originalMaterial = textMeshPro.fontMaterial;

    }

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

    }

    public void OnPointerEnter(PointerEventData eventData)
    {

        textMeshPro.fontMaterial = hoverMaterial;
    }

    public void OnPointerExit(PointerEventData eventData)
    {

        textMeshPro.fontMaterial = originalMaterial;
    }

}
``` this script is supposed to change to glow material when pointer enters. It was working yesterday but now my text just disappears when I hover over. I get no errors.

I assigned the materials in the inspector

[ivory bobcat]

When your pointer exits the target, does it return?

[final kestrel]

yes it does

[ivory bobcat]

Have you tried other materials?

For the problematic one

[final kestrel]

I created another button and another material

It still does the same.

[ivory bobcat]

Have you tried a different material for the problematic one?

[daring tundra]

Does anyone know why my input could be delayed in low frame rates? Is there a common fix for this like multiplying by Time.DeltaTime?

[polar acorn]

Are you reading input in FixedUpdate?

[final kestrel]

I created another glow material if thats what you are asking

[ivory bobcat]

Did you put it in fixed update?

[polar acorn]

If you manually set the material to the one you're using for the hover material, is it visible, even without the script running at all?

[final kestrel]

If i manually put it on the text it disappears

[ivory bobcat]

Your code looks fine at a glance. You're simply assigning different materials in pointer enter and exit.

[polar acorn]

Then the code isn't the problem, the material is

[polar acorn]

The material is invisible for whatever reason

[final kestrel]

This is the material.

[ivory bobcat]

Might want to ask it in a specialized channel

[final kestrel]

Ah all right. Thanks for the help

Uhh... Which channel do i ask on?

[analog depot]

hi there, dumb question, if I have a normalized vector3 and I want a world position from another object 2 units say in the opposite direction to that vector, what should I do?

pos here x >> obj >> vector ----->

[daring tundra]

I worded my original question wrong, it does register input correctly but registers very late when you let go of it. I'm checking whether someone is holding down the left mouse button

And it is in FixedUpdate

[ivory bobcat]

A normalized vector isn't a position but a direction. I might not have understood it all but you'd multiply a scalar with the direction and add it to the position to move in that direction.

[polar acorn]

So, you have an object, and a direction, and you want the point that is 2 units away in the opposite direction from that?

[analog depot]

yea

[polar acorn]

position + (direction * -2)

[analog depot]

• -2

?

perfecto sorry 🙂

yea that works great - thanks!

[winged meadow]

hi, how to make drop down folder like this by script ?

[polar acorn]

That's how lists and other collections are displayed in the editor

If you want a foldout without a list you'll need a custom inspector

[winged meadow]

custom inspector ? but i can't just do as unity does ?

[polar acorn]

You can. With a custom inspector.

[winged meadow]

ok tell me how

[polar acorn]

https://docs.unity3d.com/Manual/editor-CustomEditors.html

[royal ledge]

I'm not sure this is the right channel but, when creating a game for pc, unity recommends using a 10.8 size camera importing sprites at 100 ppu for example. Does this mean my tileset should be 100x100 then? Or do games usually mix ppu's. Thanks in advance

[sly wasp]

I forgot, so what is the code to generate a gameObject into a tagged object?

[cosmic dagger]

huh? what does that even mean?

[sly wasp]

how do i generate a game object inside an empty game object? (tagged empty game object)

[true pasture]

Instantiate takes a parent parameter

Is that what you mean?

[sly wasp]

pretty sure

[true pasture]

Yeah just look at the instantiate docs for the syntax

[sly wasp]

im meaning on putting it inside a tagged object
likke i need the script to find that

[true pasture]

Every object with that tag?

[sly wasp]

yea

[true pasture]

https://docs.unity3d.com/ScriptReference/GameObject.FindGameObjectsWithTag.html

And just add the thing you want to each object in the array it returns

[polar acorn]

What do you mean inside a tagged object

Like, at the same position?

[sly wasp]

generate a game object as a parent of the tagged object

same position

[polar acorn]

Generate as a parent or as a child

[sly wasp]

so how do i generate it inside every object with a tag ("obstacle")?

[sly wasp]

dis

ik

[true pasture]

It would be a child then not parent

[sly wasp]

oop

meant child sorry

but the array, do i do
public GameObject[] obstacles?

[polar acorn]

So, for each object with a tag, you want to spawn an instance of something as a child of that object

[sly wasp]

and then

obstacles = FindGameObjectsWithTags("obstacle");?

[sly wasp]

yeah

i meant the gameobject being a child of the tagged object

[polar acorn]

So, loop through a list of all objects with a tag, then spawn your object using the Instantiate overload that takes in a parent

[sly wasp]

GameObject[] obstacles;
obstacles = FindGameObjectsWithTag("obstacle");

But I am not very good at instantiating yet

[true pasture]

Its just a function theres no skill barrier lol

[young grove]

Input system is set to use both, but after I updated the package, I can't use old input system methods like GetButtonDown() how do I fix this?

[polar acorn]

Do you get an error

[young grove]

Yes

[polar acorn]

What is it

[young grove]

Get button doesn't exist in input

[polar acorn]

Show code, show error

[young grove]

if (Input.GetButtonDown("Shift")

Input does not contain a definition for GetButtonDown

[polar acorn]

You have a class named Input

[languid spire]

or just a variable

[young grove]

No

Also side problem, the unity stuff doesn't show in vscode autofill and some of the csproj files show up as not supported by c# dev kit, it's no biggie but it is bothersome

Seront in just unity

Also ide was fine a month ago when I last used it, idk y it stoped working right

[young grove]

That was the error the one I gave

[polar acorn]

Show a screenshot of it anyway

[young grove]

I renamed PlayersController to SplayerController now it's gone and working

IDK why coding is so random like this

How does renaming a file fix this issue? There completely unrelated

The error came from a complete other script

[polar acorn]

Then it seems you didn't save your script

Renaming something recompiled it

[young grove]

It was saved I opened the project 2 min ago and changed nothing

All I did was rename this unrelated script and it works

Whatever if it works it works

But anyone know why vs code doesn't like the csproj files? It just bothers me the 33 by the red x on the bottom, also it would be nice for the autofill to work with unity methods, and yes I have the unity and c#dev kit extensions and vs code package on unity end

um so my scene has merge conflicts that im not seeing on github desktop, do i have to use git to fix the merge?

[silent valley]

Hi. I'm trying out raycast and have managed to get it to work and to detect tags. I'm trying to make it so text pops up on screen. For example, if you're looking at a picture then the text "This is a picture" will pop up on screen.

[ashen ferry]

Ive got ui manager singleton controlling ui state on screen if u do that u just make public method there enabling ur text canvas and setting text element values in it then run it where u want

[swift crag]

If you had read the instructions Digi linked to you, you'd have known that already.

[jagged vortex]

Guys what do I do if my camera is in the void basically and I cant get back up to the platform im working on

nvm I fixed tit

[swift crag]

setting its position directly in the inspector can help

if you've flung it out to a wild position

[rapid mountain]

use custom tags by a script, then reference that script to the raycast to detect and display the proper text needed, i dont really use the built in unity tags because it gets clunky when you have many tags

[silent valley]

This is what I have managed to do. Only problem is if i walk backwards while I was looking at the picture. the text doesnt go away unless i go back to it and look away while i'm next to the picture

[rapid mountain]

you havent made a condition that if its out of range, the text will be disabled

its better to have a guard clause at the very start that only executes the rest of the code if the raycast has hit something, if not just return

[silent valley]

Could you explain what that is please?

[rapid mountain]

which means that if you walk backwards, there is no condition to check if you have walked backwards or specifically, to check if the raycast hit nothing

[silent valley]

Right, Gotcha. I'll save that for the morning. I appreciate the reply

[eternal knoll]

why am i getting an error here?

[ivory bobcat]

Post the error

[eternal knoll]

i am just trying to call a function from another script

[eternal knoll]

here

[ivory bobcat]

Look at the example.. yours is missing something https://docs.unity3d.com/ScriptReference/GameObject.GetComponent.html

[ivory bobcat]

That's the name of the object, not the component.

Is the component called auth manager as well?

[eternal knoll]

they are all called AuthManager

i followed tutorials on yt but theirs work and mine doesnt

[north kiln]

That's not how you call a method

[eternal knoll]

oh

wait

wow

i didnt realize

[eternal needle]

I think what you are doing with transform.TransformDirection(direction * range) is incorrect, because you are giving it a vector scaled by range, then also later using range in the raycast parameter. You could just replace
transform.TransformDirection(direction * range)
with transform.forward.

[half cosmos]

yo wut does dis mean

everytime i try to make a project

it doesn't work

and i get this message

[ivory bobcat]

Not a coding question, try asking in #💻┃unity-talk

[half cosmos]

[eternal knoll]

both is set to if (task.IsFaulted) but one works and one doesnt

when the sign up is faulted, logText.text changes but when the sign in is faulted, logText.text doesnt change, even though they are the same script

when the first one is faulted, only debug.log(signin failed) works, the code logText.text = "password is incorrect" underneath doesnt work

[wintry quarry]

Major difference between the two

ContinueWith vs ContinueWithOnMainThread

You can't touch Unity objects from a background thread

[eternal knoll]

oh

wait lemme change

the first one to ContinueWithOnMainThread?

mb because i was copying this code online so i didnt notice

[brazen veldt]

you can get TMP_Text component with GameObject.GetComponent<TMP_Text>(), right?

i have, everywhere says it works and i get null

[slender nymph]

show the relevant code, the error + stack trace, and the object you are calling GetComponent on

[brazen veldt]

https://gdl.space/duwasisipu.cpp

[slender nymph]

so if line 21 is throwing the NRE then the issue isn't the GetComponent call. it's that your GameObject.Find call is returning null

which means either that object does not exist in the scene at the time this code runs, it has a different name, or it is not active

[brazen veldt]

OOOOOOOh

did not know it needed to be active

[slender nymph]

yep, GameObject.Find does not find inactive objects
https://docs.unity3d.com/ScriptReference/GameObject.Find.html

This function only returns active GameObjects.

you'll want to get a reference a different way if you want to refer to an inactive object
https://unity.huh.how/programming/references

[north kiln]

No reaction images thanks, just use words/emoji, keeps the chat cleaner

[brazen veldt]

understandable

[silent valley]

I've been scraping my head with this one for ages. all I want is the text on the screen to go away as soon as I'm not looking at one of the objects. If I'm close to the object, it does disappear but if I'm on the edge of the raycast beam, it'll stay on my screen until I look at something else.

[summer stump]

If (raycast) returns true only if you hit something. False only when you don't (not including using layermasks)

[wintry quarry]

you need an else for the raycast if statement

[north kiln]

Also, best to use CompareTag instead of equality to check for tags

[summer stump]

Also, I would do

if (picture)
Else if (chair)
Else if (table)
Else

Instead of the else after each if statement

Or a switch with a default for when you add more things

[wintry quarry]

or better yet just using the name or some string from a component directly rather than handling it all here.

[north kiln]

If we're gonna go all the way on suggestions, I would make the raycasting script perform no logic, and have it handled by a component on the objects through an interface

but it's complicated for beginners, so simple is fine

[summer stump]

Agreed. Didn't want to stray too far, but yes

[silent valley]

That was what I wanted to do then confused myself out. I used a long cube with no mesh before so I'm new to raycasting

So what exactly is my problem here? I would of thought the else then the SetActive(false) would automatically disable the text when not looking at it

I probably sound stupid but I want to understand and not just nod my head not knowing whats going on.

[summer stump]

You need an addition else AFTER the raycast if

If (raycast)
All that stuff
Else
Set false

Because you can only get to your current code setting it false when the raycast SUCCEEDS against something that isn't those three things.

You also want it to set false when it fails (not pointing at anything)

[silent valley]

The last part is what I have tried finding online for awhile. I found a few things but none seem to of worked

[onyx ledge]

Hi everyone, the code itself isn't that difficult, so I'm writing it here. How do I get GPGS services to work on iOS as well? iOS doesn't use Google Play Store, so I don't know how to develop it

[summer stump]

Just to be clear, I meant something like this. This is trying to keep it as close to how you have it as possible. Definitley not the best way. I would have the object have an interface like Vertx said and turn its OWN text on, but this is along the lines of how you have it, but what you need to fix it

if (Physics.Raycast(theRay, out RaycastHit hit, range))
{
  if (hit.collider.CompareTag("Picture")
  {
    picturetext.SetActive(true);
  }
  else
  {
    picturetext.SetActive(false);
  }
  if (hit.collider.CompareTag("Chair")
  {
    chairtext.SetActive(true);
  }
  else
  {
    chairtext.SetActive(false);
  }
  if (hit.collider.CompareTag("Table")
  {
    tabletext.SetActive(true);
  }  
  else
  {
    tabletext.SetActive(false);
  }
}

else
{
  picturetext.SetActive(false);
  chairtext.SetActive(false);
  tabletext.SetActive(false);
}

[silent valley]

Trying that now.(Just trying to fix errors about the compare tag) I also tried the last bit with the false' earlier.

[summer stump]

You did the false's OUTSIDE the if of the raycast already?

That should have worked. hmmm

[silent valley]

i only had 3 false' like yours at the bottom. you have them in the if too

[summer stump]

They are not in the if

to show it clearly:

if (Physics.Raycast(theRay, out RaycastHit hit, range))
{
  // all the checks
}

else
{
  picturetext.SetActive(false);
  chairtext.SetActive(false);
  tabletext.SetActive(false);
}

the top if closes

[silent valley]

sorry. I've been at this since midnight. It's almost 7 am

[vital shadow]

Can u tell me the problem once again??

[silent valley]

Well, right now. I'm trying to figure this out. But the original one is Raycast. I have it so when you look at an item, text appears on screen for what the item is etc. while looking at the item, if i walk back, the text still stays on my screen unless i look literally up to the sky or go onto another object. (range is 4).

Corrected the code I sent

You run CompareTag on the collider, not the tag (of course) headslap

[summer stump]

What is "gui configuration"?

[vital shadow]

The configuration of the layout

[silent valley]

@summer stump I WOULD KISS YOU RIGHT NOW. Thank you so much. It works.

[summer stump]

I don't understand what that means either. Sorry.
Are you talking about the IDE, the Unity Editor? Why would they send it to you?
When I hear Layout, I think the Unity Editor layout, like this
https://learn.unity.com/tutorial/exploring-the-editor-layout

[summer stump]

All good, glad it worked!

[silent valley]

I'm going to study that code and compare it to my one. THANK YOU

Oh wait, sorry sorry. I thought this was the roblox studio server

Sorry boys

[north kiln]

Regardless of fixing the issue, if you've not got a configured IDE (underling errors and giving autocomplete) you need to set that up!

[slender nymph]

1. your last ) is in the wrong place
2. you do not need to cast to GameObject when using Instantiate. that hasn't been necessary for like 4 years or more

How do I make OnPointerEnter work with Unity Visual Scripting? I have a Script Graph on an Image with that node, but it just doesn't trigger. I don't think it's a raycast issue, since that same graph has an On Mouse Input event that works just fine

Could someone explain to me why the if statement (if (currentWaypointIndex >= wayPoints.Length) does not immediately assign currentWayPointIndex to 0 when the maximum number of indexes of the wayPoints array is reached? Don't get me wrong, my code works completely fine, I just wanted to ask as why it is like that?

[north kiln]

What do you mean? If the code inside the if statement executes, currentWaypointIndex becomes 0

If you're confused at how it's working you should use the debugger and step over your code to see it execute

[sour fulcrum]

You might want to be checking wayPoints.Length - 1

[north kiln]

The logic is correct

[sour fulcrum]

Genuinely correct me if I'm wrong but would currentWaypointIndex == wayPoints.Length - 1 be more accurate since the check is specific to the actual logic your trying to check?

Right now from that code alone it looks like if it fails the check it's just going to ++currentwaypointindex until the if statement clears since that distance check is going to keep hitting true (unless some outside code is changing stuff)

[north kiln]

The problem is that there is no context to explain what they are doing or how they want it to work, but the logic is correct.

[slender nymph]

if they changed the if statement to if(currentWaypointIndex == wayPoints.Length - 1) then the last index will not be used because when they get to the last index they will immediately go back to 0. their current logic is correct because they want to go back to 0 after passing the last index. which will be when currentWayPointIndex is greater than or equal to the length of the array

[sour fulcrum]

Heard

In theory the greater check will never run because the equal check will always reset it before that point, Right?

[north kiln]

Correct. Though, I generally perform checks like that too

if I do it that way all the time it saves the load to think about the other options if they're ever in my code

[toxic void]

gameObject.transform.position = new Vector3(x, y, 0);

Why do I get an error from this?

[cosmic dagger]

what class is this in?

[slender nymph]

you've probably got that inside of a static method

[toxic void]

It's inside a class I made

Am I unable to referance gameObject inside a class?

[chrome scarab]

using UnityEngine;

public class EnemyHealth : MonoBehaviour
{
    public float enemyHealth;
    public SpriteAttack killedEnemies;

    // Start is called before the first frame update
    public void Start()
    {
        enemyHealth = SetBaseEnemyHealth();
    }

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

    }
    public float SetBaseEnemyHealth()
    {
        float health1 = 100;
        health1 += killedEnemies.killedEnemies;
        return health1;
    }

Hello, I wrote a code like this, but it gives the following error:

NullReferenceException: Object reference not set to an instance of an object
EnemyHealth.SetBaseEnemyHealth () (at Assets/Scripts/EnemyHealth.cs:22)
EnemyHealth.Start () (at Assets/Scripts/EnemyHealth.cs:11)

I'm sure I selected the sprite attack file in the inspector, and the killedenemies variable was initially set to 0 as follows:

public int killedEnemies = 0;

[cosmic dagger]

you can, was wondering if it was a c# class not derived from MonoBehaviour or inside of a static method as boxfriend said . . .

[slender nymph]

the only object in that class that could be null is the killEnemies variable. where did you assign a reference to a SpriteAttack object?

[toxic void]

This is the script

[cosmic dagger]

exactly what i thought. it's inside of a regular c# class. it has no idea what gameObject is . . .

[toxic void]

So how can I referance the object the script is attached to? do I need to create a variable outside the class?

[cosmic dagger]

gameObject is an inherited property from a MonoBehaviour but your class does not derive from MonoBehaviour . . .

[chrome scarab]

Do I need to call it with void start?

[slender nymph]

what? you need to assign something to that variable

[cosmic dagger]

you need to create a GameObject field and assign that field in its constructor . . .

[chrome scarab]

Isn't it enough to set it to 0 anyway? like this: public int killedEnemies = 0;?

[slender nymph]

that's not the issue

[toxic void]

oh I see

[slender nymph]

the issue is the killedEnemies variable of your EnemyHealth class. it is a SpriteAttack variable and it is null
where do you assign to that variable?

[cosmic dagger]

when BodyPart is initialized, the calling script must pass a GameObject to its constructor . . .

[chrome scarab]

Do I need to reassign to killed enemies? bruh. Shouldn't it already be assigned in the other script?

[toxic void]

Can I just make a public variable outside the class and attach the gameobject to it in the unity editor?

[slender nymph]

where have you assigned it at all

[chrome scarab]

It's already written in my code, look, I assigned it to the sprite in the attack, and while writing the variable, I gave it the value 0 at the beginning.

[slender nymph]

and still you are thinking about the wrong variable because you've decided to give the variable the same name as the one inside the SpriteAttack class.

read this message again carefully #💻┃code-beginner message

[chrome scarab]

There is no other killed enemies variable in my enemyhealth script. I'm trying to get it from the spriteattack script.

[slender nymph]

look directly to the left of what you have highlighted. that is what is null

[chrome scarab]

it is my script file. I just asked above whether should I assign it with void start

[slender nymph]

where do you assign anything to that variable

hint: you don't which is exactly what it is null

[tame mesa]

Hello, someone can explain me why my Tilemap is outlined by orange glow ?

[slender nymph]

you have gizmos enabled

it's just a gizmo showing the selection outline. it will not show in the actual game

[chrome scarab]

Isn't it enough to assign in the inspector window? Do I need to create getComponent with void start?

[slender nymph]

assigning in the inspector is enough. provided you do that for every instance of that component

[chrome scarab]

I already did it.

[tame mesa]

I understand but how to disable it ?

[slender nymph]

disable gizmos. there's a button toggle in the upper right. but also this is a code channel

[toxic void]

Do I need to make the gameobject variable type pass by by refarance? will the changes I do to the gameobject variable in the method change the actual object in the scene if it's passed on by value?

[tame mesa]

Sorry , thanks

[slender nymph]

not for every instance you didn't. otherwise it wouldn't be throwing a null reference exception. add this line to Start: Debug.Assert(killedEnemies != null, $"Oh look, the component was not assigned on {name}", gameObject);

[cosmic dagger]

If you have a BodyPart instance in a MonoBehaviour class, you can drag a GameObject into its GameObject field, yes, but since it can only be constructed in code, you should have a constructor where you assign the GameObject variable as well . . .

[chrome scarab]

Nothing was written and no warning was received.

[slender nymph]

put it before the line that was already in Start

[chrome scarab]

I don't understand. Orc clone spawns with random enemy spawn, but why shouldn't it be assigned, I get it from prefab. Isn't it assigned to prefab?

[slender nymph]

you probably didn't assign the variable on your prefab and only assigned it on the one in the scene

[chrome scarab]

yep. it's isn't assigned to prefab

tysm @slender nymph

Why does the type mismatch occur when I select it?

[slender nymph]

prefabs cannot reference in scene objects. you need to pass the reference to it when you spawn it

https://unity.huh.how/programming/references/prefabs-referencing-components

[toxic void]

I have no idea why the instantiate isn't working, it just doesn't create anything when the game is running

[tacit river]

private void OnCollisionEnter2D(Collision2D collision)
    {
        placement.CanPlace = false;
    }
    private void OnCollisionStay2D(Collision2D collision)
    {
        placement.CanPlace = false;
    }
    private void OnCollisionExit2D(Collision2D collision)
    {
        placement.CanPlace = true;
    }```
the issue is there is a single frame when switching between 2 collisions that CanPlace becomes true and I need that to not happen

[slender nymph]

i would personally recommend use physics queries instead of relying on collision messages. you can use something like Physics2D.OverlapCircle (or whatever shape you need)

[slender nymph]

what steps have you taken to ensure that code is actually being run?

[subtle hedge]

ok so i runned into this little problem with the IK foot. So when i move the model up and down, the leg's target stay down on the ground, but when i move the cube forward the leg's target moves too and is dosen't stay on the ground to move the feet back. I know this i caused by the parenting of the target to the model, but how can i get past this issue without unparenting the targets from the model ?

public class IKMovement : MonoBehaviour
{
    public legTip[] legs;
    public float heightOffset;

    private void Update()
    {
        foreach (var leg in legs)
        {
            Ray legRay = new Ray(leg.tip.position + (Vector3.up * heightOffset), Vector3.down);
            if(Physics.Raycast(legRay, out RaycastHit hit, Mathf.Infinity))
            {
                leg.tip.position = hit.point;
            }
        }
    }
}

[System.Serializable] public class legTip
{
    public Transform tip;
}```

[maiden minnow]

Im using the old input system. How to check if the player is using keyboard or controller controls?

[queen adder]

is there an inverse of vector2.ToString()?

string.ToVector2() thingy something?

or do i have to write it

[toxic void]

This code is running, this method is the same method that moves my character, and my character moves

[slender nymph]

then Instantiate is being called therefore the object is being spawned

[wintry quarry]

you have to write it - but it would be very simple

[queen adder]

yea figured i can just splitty thingies

[slender nymph]

what would you need to convert a string to a Vector2 for anyway? 🤔

[queen adder]

   public string FromToTarget( Vector2 main, Vector2 target) // used if there's a position in the string
    {
        string toret = "";
        float magni = (main - target).magnitude;
        if((int)magni == 0)
            toret = "0 C";
        else
            toret = $"{Mathf.RoundToInt(magni)} {lyx.func.CardinalDirectionWithTwoVector3(main, target)}";
        return toret;
    }
    
    void OnEnable()
    {
        string toDisplay = NoteString;
        toDisplay.Replace();
        noteText.text = 
    }````

btw, i wanna regex a string with any vector2 strings, how can i feed the matching results to FromToTarget then replace it that

is there a regex that outs something?

Regex.replace dont, does it?

[toxic void]

Well it isn't, idk why, no object is spawning

[slender nymph]

it is. it might be destroyed immediately but if that code is running and you don't see errors in your console then it is being spawned

[toxic void]

I don't see how the object is destroyed, nowhere in my game is there a line of code that destroys an object

[slender nymph]

well like i said, if that code is running and you don't see errors in your console then it is being spawned

add this line directly after it and show what it is printing: Debug.Log($"Instantiate has spawned a clone of {BodyPartPrefab.name} from {name}");
preferably screenshot the entire console window

[queen adder]

    public string FromToTarget( Vector2 main, Vector2 target) // used if there's a position in the string
    {
        string toret = "";
        float magni = (main - target).magnitude;
        if((int)magni == 0)
            toret = "0 C";
        else
            toret = $"{Mathf.RoundToInt(magni)} {lyx.func.CardinalDirectionWithTwoVector3(main, target)}";
        return toret;
    }

    Vector2 StringToVec(string ss) { return Vector2.zero; } 
    
    void OnEnable1()
    {
        string pattern = @"\(\d+[.\d\s]*,\d+[.\d\s]*\)";
        string input = NoteString;
        

        
        string result = Regex.Replace(input, pattern, FromToTarget(MainCharacterController.MainPosition, StringToVec( ""/* regex match */ )));
    }``` How can i make this work?

[toxic void]

Ok it is instantiating the object, but why can't I see the objects in the viewport?

in the game*

[slender nymph]

is this 2d?

[toxic void]

sorry too much using blender

[toxic void]

yeah\

yeah

[slender nymph]

then either the objects are not being spawned within the camera bounds or they are behind the camera

[toxic void]

it has the same transform as the character before it moved, so I don't believe it is hidden anywhere

[slender nymph]

screenshot the inspector for it

[slender nymph]

not the prefab, one of the objects actually in the scene

[toxic void]

idk why the position is 0 too thats weird

[slender nymph]

okay so it is at the same exact position as whatever its parent is. now keep in mind that child objects will also move when their parent moves

[toxic void]

ohhhhh

[fading slate]

Hi i just started today and i ran into a problem . The script i make for the ball doesnt work and it gives me no error

[toxic void]

How do I instantiate it without making it a child

I get it now

[fading slate]

it should look like this but mine doesnt

[slender nymph]

the second parameter you are passing to Instantiate is a transform. that specifies the parent

[slender nymph]

have you saved?

is your code exactly the same?

[polar acorn]

Does the file name match the class name

[fading slate]

oh wait wait let me take i step by step so

[slender nymph]

ah yeah, didn't even catch that

[fading slate]

i should name the script to Ball

?

[slender nymph]

that should be both the file name and the name of the class in the code, yeah

although now that i think about it, if you're on latest LTS that won't really matter

[polar acorn]

It doesn't matter what you call it as long as the file name matches the class name

[fading slate]

this is it by far
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class NewBehaviourScript : MonoBehaviour
{
public Rigidbody2D rb2d;

private void Start()
{
    rbd2.velocity = Vector2.left;

}

}

[slender nymph]

yeah the class name is NewBehaviourScript. you'll want to change that to Ball

[fading slate]

so i should say public class Ball

[slender nymph]

yes. just like the tutorial you are follow does

[fading slate]

alright thanks a lot, i was a bit confused, this is really my first time having any encounter with coding

Assets\Scripts\Ball.cs(11,9): error CS0103: The name 'rbd2' does not exist in the current context
i got this now 😭

[slender nymph]

yep, you had that before too 😉

[fading slate]

and it still looks like this

assuming you are using visual studio and not vs code, that is

[fading slate]

i just figured it out now, i confused them with eachother

[toxic void]

void MoveSnake()
    {
        if (!(snakeDirection == Vector2.up && snakeY == 4) && !(snakeDirection == Vector2.down && snakeY == -4) && !(snakeDirection == Vector2.right && snakeX == 8) && !(snakeDirection == Vector2.left && snakeX == -8))
        {
            prevFrameSnakePosition = gameObject.transform.position;
            gameObject.transform.position += new Vector3(snakeDirection.x, snakeDirection.y, 0);
        }
        previousSnakeDirection = snakeDirection;
        snakeX = (gameObject.transform.position.x < 0)? gameObject.transform.position.x + 0.5 : gameObject.transform.position.x -0.5;
        snakeY = (gameObject.transform.position.y < 0) ? gameObject.transform.position.y + 0.5 : gameObject.transform.position.y - 0.5;


        GameObject bodyPart = Instantiate(BodyPartPrefab, prevFrameSnakePosition, new Quaternion(0,0,0,0));
    }

How can I save the bodypart variable at the end so that I can access it after the method finishes to do an operation on one of it's public variables every time this method runs? I thought of using arrays but that complicates stuff and means I need a 180 elements long array of gameobjects...

And I want to keep this simple as this is a game of snake

[slender nymph]

new Quaternion(0,0,0,0) is not a valid quaternion. use Quaternion.identity instead

[toxic void]

it works tho

[slender nymph]

that doesn't make it correct

[toxic void]

wdym

[uncut dune]

whats this

[ivory bobcat]

Guessing foreach and modifying the collection

[slender nymph]

i mean new Quaternion(0,0,0,0) is not a valid quaternion. use Quaternion.identity instead

[toxic void]

Yeah I did it can you please help me with the question

[uncut dune]

but what does it mean, cant I modify a dic?

[polar acorn]

What was your intention using 0,0,0,0? What orientation did you want to end up at?

[slender nymph]

you probably want a list of your body parts in the class. then just add to the list when you instantiate one. you're already storing the clone in a local variable, just add that to the list

[north kiln]

https://unity.huh.how/programming/common-errors/runtime-exceptions/invalidoperationexception/collection-was-modified

[toxic void]

It's a 2d object and I wanted it to have the default rotation

[polar acorn]

And 0,0,0,0 isn't that. Quaternion.identity is, which is 0,0,0,1

[toxic void]

alr, it didnt actually make any difference though

[ivory bobcat]

You cannot modify a collection when you're traversing through it with foreach. Foreach promises that every element will be visited (unless you do an early escape) thus you'll get an error as you're violating the promise (probably more complicated stuff under the hood but that's the gist of it).

[uncut dune]

got it

[toxic void]

so I dont really get what was the point of doing that

[uncut dune]

so how do I modify it without

creating an exception

and iterating thru all objects of a dic

I mean all keys

[ivory bobcat]

Maybe post more of what you're trying to do. Likely you need to take a different approach to this.

[uncut dune]

this is the loop

[ivory bobcat]

Lots of folks are here. I'm on mobile and just doing what I can. Other dudes here are outstanding though.

The quick and dirty solution would be to copy the keys collection and iterate it

Allowing you to modify the actual dictionary

[uncut dune]

yah that would work if I put them in a list

since they would be the same keys as the objects of the list

[ivory bobcat]

var copy = new List<...>(keys);

[signal coral]

What's the reason for this code?

 if(number == 0)
                            {
                                enemiesToBeSpawned.Remove(enemies);
                            }

[slender nymph]

yeah that's what is causing the error

[ivory bobcat]

Reminder, it's the dirty solution so if performance is a factor you may want to consider a different approach

[uncut dune]

so this dic is basically the enemies I will spawn in an area so if there is no more enemies that will be spawned

why keep the key

[uncut dune]

I was thinking that

[slender nymph]

and it seems like they just remove the object when done spawning them and are doing it for every key in the dictionary. so why not just clear the dictionary after the foreach loop?

[signal coral]

So it's a Dictionary<GameObject, int> ?

[uncut dune]

yes

[thorn vessel]

how do I see my particle system? Like turn it on when colliding with something?

[uncut dune]

well because when a certain number of enemies are spawned it waits and when I kill them all the others get spawned

so there arent so manny enemies

[neon stirrup]

Hi I have a idea and don’t know how to do it

[slender nymph]

then instead just add the enemies you want to remove from the dict to a list and loop over that list and remove them from the dict after the foreach loop. your entire issue stems from attempting to remove them during the foreach loop

[thorn vessel]

This error keep on popping up
"MissingComponentException: There is no 'ParticleSystem' attached to the "Bird" game object, but a script is trying to access it.

[slender nymph]

did you read the error?

[thorn vessel]

i did

[slender nymph]

and what conclusion did you come to?

[thorn vessel]

im missing something

[uncut dune]

is that the best way to do it? will I get optimization issues later?

[slender nymph]

well it's certainly better than what you are trying to do now

[uncut dune]

ur "bird" has no particle system in it, click add component and add a particle system

[uncut dune]

alright thank you!

[thorn vessel]

oh ill try it now

thanks

[slender nymph]

yes, your "Bird" gameobject does not have a ParticleSystem on it, but a script is trying to access it. You probably need to add a ParticleSystem to the game object "Bird". Or your script needs to check if the component is attached before using it.

either that or you are calling GetComponent on the incorrect object 😉

[thorn vessel]

oh ok thanks 😄

You want to only spawn max allRooms[CurrentRoomType].NumberOfEnemiesAtATime enemies?

yes pretty much

[toxic void]

Is there a way to remove an element from a list and make all indexes after it shift one place to the left so that it wont leave an empty index number?

[fading slate]

I have this exact same script as the tutorial i watch but i get the CS0103 The name 'rbd2' does not exist in the current context But the guy in the tutorial doesnt get it

[uncut dune]

can u show the rb and the script in the inspector?

[queen adder]

you need to drag the rb2d

[keen dew]

The guy in the tutorial didn't write "rbd2" like you did

[queen adder]

into the inspector

[cosmic dagger]

Your code doesn't have rbd2. Check it again . . .

[ivory bobcat]

https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.list-1.remove?view=net-7.0

[fading slate]

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

public class Ball : MonoBehaviour
{
public Rigidbody2D rb2d;

private void Start()
{
    rbd2.velocity = Vector2.left;

}

}

This is my code

[queen adder]

or you can add rb2d=GetComponent<Rigidbody>() in the start

[uncut dune]

rbd2.velocity = Vector2.left; its not rbd2

its rb2d

ur have an error

[cosmic dagger]

Read how you spelled the variable . . .

[uncut dune]

rb2d.velocity = Vector2.left; @fading slate change it to this

[signal coral]

This is kind of messy, because dictionary doesn't have remove if. Should mostly work though.

var currentNumberOfEnemiesToSpawn = allRooms[CurrentRoomType].NumberOfEnemiesAtATime;
var toRemove = new List<GameObject>();
foreach(var enemyToSpawnKeyValue in enemiesToBeSpawned)
{
    var enemy = enemyToSpawnKeyValue.Key;
    var enemyCount = enemyToSpawnKeyValue.Value;
    var count = Mathf.Min(enemyCount, currentNumberOfEnemiesToSpawn);
    currentNumberOfEnemiesToSpawn -= count;
    var enemiesLeft = enemyCount-count;
    enemyToSpawnKeyValue[enemy] = enemiesLeft;
    if(enemiesLeft == 0) toRemove.Add(enemy);
    for(int i = 0; i<count;i++)
    {
      GameObject colliderCheck = Instantiate(Spawner, roomPos + new Vector2(Random.Range(-rooms.Point.x, rooms.Point.x), Random.Range(-rooms.Point.y, rooms.Point.y)), Quaternion.identity);
                                ColliderCheck colliderStats = colliderCheck.GetComponent<ColliderCheck>();
                                colliderStats.enemyType = enemies.GetComponent<EnemyHealth>().EnemyType + 1;
                                colliderStats.enemy = enemy;
    }
}
foreach(var enemyToRemove in toRemove)
{
  enemiesToBeSpawned.Remove(enemyToRemove);
}

paste it there

That's what happens when you normally remove an element with Remove . . .

Yes idk, i mean i just downloaded everything today and configured it so i think it should be working, i am a bit confused

why this funny af

[queen adder]

cause it is

[queen adder]

if you type your rigidbody name and then add . does it show some stuff?

[fading slate]

😭 😭 So it will be a long journey

[uncut dune]

I remember when I started copying tutorials slowly and always having errors lmao

[signal coral]

The reason for this mess is that you can't edit a collection while iterating over it. If you used a list like this

public class EnemySpawnInfo
{
public GameObject Enemy;
public int countLeft;
}

And then a list like this List<EnemySpawnInfo> enemySpawnInfo;

You could just iterate over it backwards and remove elements as you go Like this.

for(int i = enemySpawnInfo.Count-1;i>=0;i--)
{
    var enemyInfo = enemySpawnInfo[i];
    var count = Mathf.Min(enemyInfo.Count, currentNumberOfEnemiesToSpawn);
    currentNumberOfEnemiesToSpawn -= count;
    enemyInfo.Count -= count;
    if(enemyInfo.Count == 0) enemySpawnInfo.RemoveAt(i);
    for(int o = 0; o<count;o++)
    {
      GameObject colliderCheck = Instantiate(Spawner, roomPos + new Vector2(Random.Range(-rooms.Point.x, rooms.Point.x), Random.Range(-rooms.Point.y, rooms.Point.y)), Quaternion.identity);
                                ColliderCheck colliderStats = colliderCheck.GetComponent<ColliderCheck>();
                                colliderStats.enemyType = enemies.GetComponent<EnemyHealth>().EnemyType + 1;
                                colliderStats.enemy = enemyInfo.Enemy;
    }
}

some could say its a cannon event

Which would simplify things

[fading slate]

yup

got it thank you so much

@signal coral will this work?

I almost didnt have to change anything

instead of removing the enemies Im adding them into the list

and then after that foreach it starts deleting them

[signal coral]

there is one case where this code works kind of wrong:
if allRooms[CurrentRoomType].NumberOfEnemiesAtATime is for example 2
and int number = enemiesToBeSpawned[enemies]; is 4
it will spawn 4 enemies. Even though I think you want to spawn just 2

That's why I did:
var count = Mathf.Min(enemyInfo.Count, currentNumberOfEnemiesToSpawn);

[uncut dune]

why would that happen

[signal coral]

you only check if currentNumberOfEnemiesToSpawn is bigger than 0

[uncut dune]

would that cause any trouble?

[signal coral]

If it's bigger than zero, but smaller than " int number = enemiesToBeSpawned[enemies];" it will spawn more enemies than intended.

[acoustic arch]

Unity tells me it cant find instance of an object in ListItems() line 31
https://hatebin.com/wehhffnipf
this script is what the first references, cards get added to the list when bought in the buy script
https://hatebin.com/ehhqqjcpjf

[signal coral]

You should go through that code and try to understand the difference between the code I wrote and the code you wrote.

[wintry quarry]

obj.transform.Find("cardImage") is clearly returning null then

[polar acorn]

The InventoryCard does not have a child object named cardImage

[uncut dune]

what if my while statement

now is like this

[signal coral]

Yeah that's one way to do it

[uncut dune]

okay thank you

[acoustic arch]

i know but i dont know how to fix it

[signal coral]

although there is one more problem if you do it like that. when you do "int number = enemiesToBeSpawned[enemies];" It makes a copy

[wintry quarry]

make sure such an object actually exists in the prefab

[signal coral]

at the end of your while loop you need to reassign it into the dictionary

like enemiesToBeSpawned[enemies] = number;

[uncut dune]

OHHH

so I should access it thru number

[acoustic arch]

currently if i have a card it detects its there and generates a blank card image not the one inside the card from the inventory list

[uncut dune]

should I call it directly?

[acoustic arch]

so it just doesnt grab the sprite for it

[wintry quarry]

i don't knmow what that means but this error is straightforward

[signal coral]

That's okay, but a bit slow. Should be fine in your case though

[wintry quarry]

the InventoryCard prefab you assigned does NOT have a child object with the name "cardImage". To fix it, make sure such an object exists

and has an Image component. The rest is noise.

[uncut dune]

this way?

yup Im missing one

I'll change it now

[signal coral]

Yeah

[acoustic arch]

so i should change InventoryCard, to the prefab of the actual cards going into the inventory?

[uncut dune]

but other then that is it okay?

[wintry quarry]

I have no idea what that means

[acoustic arch]

those are currently as scriptable objects

[wintry quarry]

show what object you assigned to the InventoryCard variable

[acoustic arch]

like

[signal coral]

Best way would be like this though, but this is not really performance critical code, so this is fine

[acoustic arch]

this

[wintry quarry]

does it have any children?

Your code is trying to find a child object of this

iwth the name "cardImage"

[acoustic arch]

no it doesnt

[wintry quarry]

if no such child exists, that's why your code is failing

make sense?

[acoustic arch]

yeah

[wintry quarry]

so with that knowledge, you should be able to fix this, yes?

either changer the code

[acoustic arch]

so how do i change it so it looks for the image on that card tho?

[wintry quarry]

or change the object

[acoustic arch]

not in the child

i understand it

[wintry quarry]

is that not really simple?

[acoustic arch]

the tutorial im watching has a button with the icon inside it

while mine is just 1 image

not a child of a button
