[deft grail]

where are you doing lerp? i dont see

[faint agate]

I had to delete it cause it wouldn't let me save since I was doing it wrong and there was an error.

I am not very good at this, I just need advice

[lusty flax]

i would greatly appreciate some help :]

[ivory bobcat]

Try logging what it overlapped.

I'm assuming not working refers to you overlapping more than zero objects.

[teal viper]

You could use a ref keyword to pass value type parameters by reference.
That being said, it is sort of against c# design principles. So maybe think of a different approach. For example passing in a delegate.

[undone wave]

how would one do that

[ivory bobcat]

If you're just in need of a generic coroutine, maybe pass the coroutine a delegate that takes a float (delta time) and let whoever calls it define the implementation with the delegate?

[eternal needle]

One thing is you cant run coroutines in an SO. The script using it will have to run their own

[undone wave]

im having trouble understanding how delegates work and how to implement them

[undone wave]

isn't it possible to store an IEnumerator in the SO and then run them in other MonoBehaviour objects?

that's what i'm planning to do for now

[ivory bobcat]

Why would you want to do that?

[eternal needle]

Theres basically no point in using the SO there. You could just make some static method

[faint agate]

i am still very confused

[undone wave]

{
    public static IEnumerator scaleChange_outQuad(ref Vector3 targetProperty, Vector3 targetValue, float animationTime)
    {
        ...
    }```
would this work? (delegates yet to be implemented, i don't know how they work yet, trying to find explanations for them)

[ivory bobcat]

I don't believe iterators can have reference variables.

[undone wave]

oh

[eternal needle]

Yea you cant use ref or out. Honestly you might be trying to do too much with the method, like how often will this really be used that classes cant just implement it themselves?

Otherwise youd be looking into recreating what tweening libraries already do

[faint agate]

playerObj.localScale = new Vector3(playerObj.localScale.x, startYScale , playerObj.localScale.z);

Im trying to smooth scale the "startYScale", but thats called in Start and I need it there since it holds the standing position of the entire player

[lusty flax]

it shows as if they're overlapping 0, nothing (late response, sorry)

[ivory bobcat]

Define "not working".

[lusty flax]

basically, the script is supposed to prevent you from placing the objects over each other, but this is not occuring as it is unable to properly check if they overlap. consequently, the objects simply overlap regardless

[ivory bobcat]

Is the model destroyed or child to the building?

[lusty flax]

If the script worked, ideally, the objects that would be succesfully placed would be parented to a "Buildings" empty to house all of the placed objects. Objects that were not successfully placed would simply be Destroyed.
However, as the script does not work, what instead happens is that all models are simply kept in the "buildings" empty

would it be easier to do this another way? i find that this might be difficult to implement when adding tilemaps into the mix later on

[ivory bobcat]

So the models weren't destroyed, meaning they were overlapping zero objects.

[lusty flax]

yes, and this happens regardless of whether they were visibly actually overlapping things

[ivory bobcat]

Log the actual collider you believe your working with: ```cs
Collider2D collider = model.GetComponent<Collider2D>();
Debug.Log($"Click here once during runtime to see {collider.name} highlighted in the scene", collider);

Check if it's the correct collider and at the expected location

[lusty flax]

yep it is the right collider

[ivory bobcat]

If model isn't the correct target (say a prefab instead of an actual object in the scene), you'll likely get unwanted behavior

[lusty flax]

would there be a simpler way of doing this?

this seems like it would become complicated with more complex shapes or maybe tilemap colliders

i just want to make sure that players can't place objects over others

[ivory bobcat]

Can you show what two objects would be overlapping but isn't?

[lusty flax]

(that 0 is printing the amount of colliders found overlapping)

those two blue objects are the things

the objects

[ivory bobcat]

Do they both have collider2ds?

[ivory bobcat]

Can you show the transform component for each?

An image of their bounds in the scene view would be nice as well.

[ivory bobcat]

Are you attempting to evaluate after moving the object?

If you are, you may need to sync the collider https://docs.unity3d.com/ScriptReference/Physics2D.SyncTransforms.html

[daring dragon]

why does my noise code break wnvr the seed is anything but 1 float xCoord = (float)x / (mapSize * zoom) + seed;
float zCoord = (float)z / (mapSize * zoom) + seed;
float noise = Mathf.PerlinNoise(xCoord,zCoord);

[teal viper]

How does it "break"?

[lusty flax]

Thank you! Now there's only one small issue...

The system works as intended, but I am unable to place objects right next to each other

[daring dragon]

It’s like it goes just completely random or zooms out super far or something

Wait I will send screenshot

[lusty flax]

i need to have a space or it will trigger, and I want to be able to place them edge-to-edge

[daring dragon]

it should stay like the left side

[teal viper]

Perhaps the seed should be divided by map size and zoom as well? I'm not entirely sure what the intention is.

[lusty flax]

nvm i can just shrink the colliders a bit. Thanks!

[daring dragon]

i am doing that because it seems to break if the value put into the perlin noise is anything bigger that one or less than 0

[teal viper]

Yes, the perlin noise is supposed to be sampled in the range between 0 and 1

[daring dragon]

So how do I do it correctly, should I add seed to x and then divide by maximum seed number or something?

[teal viper]

Try it

[daring dragon]

Ok

[teal viper]

Actually, maybe it doesn't have to be in the range of 0-1, but integer inputs would always return the same value iirc.

[daring dragon]

I will check that

Ok yeh it doesn’t need to be within that but I’m still getting the weird thing

My code is now

float xCoord = (float)x + seed / zoom ;
float zCoord = (float)z + seed / zoom;
float noise = Mathf.PerlinNoise(xCoord,zCoord);

[teal viper]

Well, your x/z is not affected by zoom now

Do you understand the order of arithmetic operations?

[daring dragon]

Pemdas

Ok fixed that

That was just me being silly

I will check if it’s still broken

Ok I think it’s still broken I’m just testing with different zooms to make sure it doesn’t just appear that way

Oh my god

I had my seed being recalculated for every pixel

I’m so dumb lol

Thank you I fixed it

[teal viper]

That explains it

[remote osprey]

I'm super confused on events

Hey everyone, how yall doing?

so I have a GameManager Class that handles events like drawing a card to the players hand, for example.

But I want to make a card whose effect when being played is drawing a card from the deck to the hand

I already have this code ready, but I have no idea how to issue the draw command from the card script to the game manager

I've looked into tons of event handler tutorials, like this one https://www.youtube.com/watch?v=k4JlFxPcqlg&ab_channel=Unity but I'm still confused on how to implement this

Any help is greatly appreciated

[teal viper]

You'd typically have the event forwarded up the logical hierarchy. For example:
Card -> HandController -> GameManager. And the game manager would call the required logic in response to the event.

So for this to work, you'd need to subscribe to events in reverse order. The game manager would subscribe to events in each hand, which the hands would subscribe to events in currently active cards.

You don't have to do it via events btw.

[remote osprey]

Oh , ok

I got it!

it was actually just making the event on Card object

then subscribing the Game Manager to the CardDraw Event on the card Object

seems to be working well! 🙂

Thank you for your help, Dlich!

[timber tide]

My card game works like: CardUI -> CardUIManager -> CardManager

if I were to redo it I'd skimp on the UIManager because even though it's nice to separate the UI logic, the editor makes it easy to kinda bind a lot of stuff directly from the UI to the manager

[remote osprey]

oh i know

it just a little weird making the card control the game object

i feel thats better practice

at least it makes me feel more comfortable knowing every interaction between scripts are made through events

on other note, i want my draggable object event to acess a specific game object, how would i do that without assigning this script to the object?

[teal viper]

What GameObject does it need to access and why?

[remote osprey]

a region that when my object/card is dropped on it, the card's effect is called

so i need to know if the mouse is on top of this region

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

public class MouseOver : MonoBehaviour
{
    public bool isMouseOver = false;
    void OnMouseEnter()
    {
        isMouseOver = true;
    }
    void OnMouseExist()
    {
        isMouseOver = false;
    }
}

So i created a MouseOver class to update when mouse enters or leaves the region in isMouseOver bool variable

I want to access that variable of that specific region

this region is a game object

[teal viper]

You could let the game manager know the current mouse overed object and then use that in your logic.

[remote osprey]

makes sense

so basically, MouseOver event passes a message to GameManager object which then passes that message to the Draggable class

i think i rather pass it directly to Draggable

tbh i think its best to let the draggable initate the event and then ask the MouseOver if mouse is over the region

ok i'm starting to get it

so basically, its the same thing iwth the cards

[teal viper]

Ideally, draggable class shouldn't run any logic like that. It should invoke an event on drag or drop or something and some script higher in the logical hierarchy should handle it.

[remote osprey]

the main problem is that draggable doesnt know its dragging a card, so this makes me think that the Card should implement its own onDragEnd event

separate from Draggable

then the OnDragEnd event should ask GameMManager to handle the OnDragEnd event

I need to pass some parameters to it, looking into that rn

[remote osprey]

bazinga

it works!

the event handler just freezes while i'm holding the card

it only changes the isOver state after i drop the card

could it be because raycaster only detects the first element it hits?

[teal viper]

Probably. Hard to say anything without more context.

[remote osprey]

I mean, this is my Region code https://paste.ofcode.org/9sFqGLP2jCa63Nm9HQ4BDp

and this is my draggable code https://paste.ofcode.org/383pAF5KTsHbGTxApxDr8Ki

this is probably all the code that is involved

the region is a plane and the object being dragged is a Card, which is a right cuboid

My Camera is orthogonal and it has a Physics Raycaster

So i when I'm dragging the card, it blocks the ray to the region

Region in red, card is the red/green/white object

card is over the regions

and a GameManager object has an Event System in it

this is the object hierarchy

that should be enough info, i think

We don't help with ChatGPT code

You should really consider learning to do it yourself. ChatGPT is a tool that can help with small blocks of code and suggestions, but it won't be able to spoonfeed you a whole MonoBehaviour like this

[eager spindle]

understand what you're typing before sending it here 🥱

dont be a genAI crutch

if you do end up as a software engineer and get sent to an airgapped development environment nobody can save you

plus the comments explain what the code does

its clear you dont know what you want the code to do for you; when it comes to asking programming questions narrow down what is actually wrong with the code rather than sending us the whole script, nobody got time for that

[thorn fiber]

Hi all, having some trouble with camera rotation in an RTS-style setup (trying to learn-by-doing rather than use Cinemachine). Was able to get a beautiful, smooth Slerp movement by rotating the camera around it's own axis but I want it to rotate around the focal point...

RaycastHit hit;
if (Physics.Raycast(cameraInstance.transform.position, cameraInstance.transform.forward, out hit, Mathf.Infinity, LayerMask.GetMask("Ground")))
{
    // Use the hit point as the rotation point
    rotationAxis = hit.point;
}
// Calculate rotation delta based on mouse movement
rotationMouseDelta = Mouse.current.delta.ReadValue();
// Apply rotation only if isRotating is true
if (isRotating)
{
    // Rotate around the rotation axis in world space
transform.RotateAround(rotationAxis, Vector3.up, rotationMouseDelta.x * Time.deltaTime * rotationSpeed);
}```
Have done some debugging, the if conditions are working and the ray cast is setting the correct point. However, this still rotates the camera around its own y axis. Would appreciate any help!

[burnt vapor]

Is this ChatGPT code?

[slender nymph]

considering the comments are all just describing the obvious, there's no way it isn't

[burnt vapor]

That's what I thought, yeah

[thorn fiber]

No, I've asked it questions but I try to ask things like what's the difference between x and y, but I try to avoid asking for code as that wont help me learn it

iirc the comment structure here came from a tutorial, which is how I ended up with the slerp rotation around local y. I just kept/modified it as I tried to work out how to change it to a rotateAround.

[topaz mortar]

This is UGS Cloud Save.
How/where can I find information on what this return type is and how I process it?

[thorn fiber]

Oh ffs... I worked it out. I can't find a problem with the code because it's correct! It's in LateUpdate and I wasn't using a return; to break out, so other movement code was borking it.

[thorny prawn]

bro chill i am designer i just need the mechanism that's why i use it
its ok to use Ai for stuff you know and so far its working but prompting and iteration is hard for me
you are saying like Ai itself is more useful than u . i am using it is for fast process only

[burnt vapor]

Except you don't know the code, or you would have knows the issue.
Neither do you know debugging, or you could have used your experience to find the issue yourself.

It's not about "being fast" or "knowing the code". Sharing code in here and expecting us to fix it is one thing, but sharing AI generated code you likely didn't spend more than 5 seconds reading yourself is just lazy

And it's not up for discussion. This is a beginner coding channel and we do not help people that resort to AI to develop their game. It never works.

[thorny prawn]

slider 1 works but movement for slider 2 is not working idk the issue
i can read most after debugging and things alredy sorted

its beginner friendly channel thay's why i asked

[burnt vapor]

You can right click the ApiResponse and navigate to its definition. Alternatively you can do the same for GetItemsResponse

Other than that, not sure. I never used this

[stone elk]

why didn't one of my variables in my list change in the editor when i retyped it in the script?

[languid spire]

because once a variable has been serialized once the editor version always overrides the script version

[stone elk]

ok thanks for letting me know

[kindred halo]

I'm trying get the yRotation on update and whenever sliding is true but I can't find a way to store it without using it with Quaternion.

transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
yRotation = transform.localRotation;
if (player.isSliding == false)
{
    RotateBody();
    xRotation = Mathf.Clamp(xRotation, -40f, 90f);
}
else if(player.isSliding == true)
{
    yRotation = Mathf.Clamp(yRotation, -90f, 90f);
    xRotation = Mathf.Clamp(xRotation, -90f, 90f);
    transform.localRotation = Quaternion.Euler(xRotation, yRotation, 0f);
}```

[thorny prawn]

here i am cheking a bool name axisX=true in start()
buttonXY.onClick.AddListener(() => ButtonClicked(buttonXY, true, true, false));

    {
        // Update button states
        UpdateButtonState(clickedButton);

        // Determine which axis to assign based on the clicked button
        axisX = axisA;
        axisY = axisB;
        axisZ = axisC;

        // Update slider states
        if(clickedButton == buttonXY)
        {
            if(slider1 != null)
                slider1.value = lastValueX;
            if (slider2 != null)
                slider2.value = lastValueY;
        }
        else if (clickedButton == buttonYZ)
        {
            if (slider1 != null)
                slider1.value = lastValueY;
            if (slider2 != null)
                slider2.value = lastValueZ;
        }
        else if (clickedButton == buttonZX)
        {
            if (slider1 != null)
                slider1.value = lastValueZ;
            if (slider2 != null)
                slider2.value = lastValueX;
        }
    }```
but in update i am checking for Slider currentSlider = GetCurrentSlider(); which is 
```Slider GetCurrentSlider()
    {
        if (axisX || axisZ)
            return slider1;
        if (axisY)
            return slider2;

        return null;
    }```
so axis X is alredy true in start but its giving null error

https://hastebin.com/share/ivecifulaq.csharp

no active slider found is messag

[languid spire]

axisX is false in Start

[thorny prawn]

no current active button is XY one so its active

[astral falcon]

Does anyone know, what the unity UI button is deriving from as default inspector (editor) script?

Nevermind, just found it myself. its ButtonEditor for anyone curious 🙂

[languid spire]

how do you figure that? axisX only gets set on button click so when Slider currentSlider = GetCurrentSlider();
is called in Update axisX is false

[thorny prawn]

oh i get it

i am not assaigning them but checking them my bad

[barren vapor]

Basicly my game is about driving a car (top-down 2D). This is the simple movement of the car:

// Update is called once per frame
    void Update()
    {
        if (Input.GetMouseButton(0)) {
            //Car rotation
            Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            Vector3 perpendicular = transform.position - mousePos;
            transform.rotation = Quaternion.LookRotation(Vector3.forward, perpendicular);
            //Car movement
            rb.AddForce(gameObject.transform.up * -speed * Time.deltaTime);
        }
        transform.Rotate(0, 0, Input.GetAxis("Horizontal") * -rotationSpeed * Time.deltaTime);
        if (Input.GetKey ("space")) {
            //Car movement
            rb.AddForce(gameObject.transform.up * -speed * Time.deltaTime);
        }
    }```

If enemy cars (which chase your), bump into you, you start rotating around like my car gets a sort of velocity against the side or smt. Then for example turning right is harder as turning left.

Is there a way to fix this?

I can fix it by freezing the rotation constraint, but then it doesn't feel natural when enemy cars bump into you.

[languid spire]

to start with you should not be setting the transform and the rigidbody, use one or the other.
Second rigidbody changes should be in FixedUpdate

[fluid haven]

Has anyone ever gotten this error before, or knows how to fix it?

[barren vapor]

oh yeah my bad I see it now. I returned after a long time back to unity. I think the main problem is here cause I use transform to rotate and bumping into my side gives a rigidbody rotation.

Well this is what basicly happens in a video (the red cars bumped into my side and I start turning around. I basicly just move forward and not left or right.)

[dusky pike]

I have a really random bug that i dont understand at all...

I have a dictionary which stores all tiles in a 3d game.
If i start the game everything works.

But when i change stuff in the code and recompile the dictionary is always empty

Do Dictionaries get cleared after recompile?

[languid spire]

yes, dictionaries are not serialized

[ivory bobcat]

Are you using a third party serialized dictionary? Changing the script may reset the inspector fields to their default values.

[dusky pike]

what does that mean?^^*
How do i change it?

Sry im a beginner

[languid spire]

this means that Dictionaries are not saved by Unity, The only way to change it is by using 3rd party assets

[dusky pike]

Ah unlucky

[dusky pike]

Is there any function that gets called after Start?
And after every recompile?

[languid spire]

these
https://docs.unity3d.com/ScriptReference/AssemblyReloadEvents.html
are called before and after recompile. There is nothing called after Start

[burnt vapor]

If you want to invoke code a period after start, use a Coroutine or Invoke

[kindred halo]

transform.Rotate(Vector3.left * mouseY);
transform.Rotate(Vector3.up * mouseX);
can we calculate the rotations of these and add them to a transform once a if statement is false?

[languid spire]

if the error is saying Line 4 in your code but Line 4 in your IDE is blank it would tend to suggest that the code that Unity is using is not the same as the code in the IDE

[ionic topaz]

So I'm getting a rigidbody2d player to move on moving platforms (the moving platforms use transform.position to move), like most I've tried parenting the player to the platform, however this broke the player movement, but if the platform's moving code is in fixedUpdate it does work, I'm glad it does however I know moving transform.position in fixed update isn't recommended, does anyone know a better solution or can confirm if what I'm doing is okay?

[charred spoke]

The proper way to do moving platforms is to calculate the velocity of the platform and add it to the players velocity after velocity from input has been calculated

[ionic topaz]

that sadly is not an option for me due to my players movement code

[wide stag]

I save all scripts and editor has update this

[trail heart]

Why not?

[ionic topaz]

My player is using Addforce to move which is alread ytricky to work with moving platforms but the actual movement is: cs float targetSpeed = xInput * moveSpeed; float speedDif = (targetSpeed - rb.velocity.x) * currentAcceleration; rb.AddForce(Vector2.right * speedDif);

(sorry that's hard to read)

[cosmic dagger]

then format the !code so it's easy to read . . .

nnice, place cs on its own line for highlighting . . .

[ionic topaz]

oops

[trail heart]

Why not add the platform's speed to your rb velocity or as another force
Forces from multiple sources stack

[ionic topaz]

I tried that...

Things went badly

[cosmic dagger]

i don't see why you can't add the platform's velocity? you're already subtracting the player's current velocity . . .

[ionic topaz]

getting them to sync up correctly just never worked

I could get close by hardcoding some multiplier

but it was never great

OHH

I think I see what you mean

I'll report back

[trail heart]

You might have to remove the friction between the platform and the character to stop it from physically also moving the character

But other than that adding velocity from one source to the current velocity should be exact

VelocityChange may be a better way to do it than directly changing velocity but I'm not totally sure what the precise difference is

[ionic topaz]

(that's already the case)

Okay reporting back, I've just done ``` float targetSpeed = xMovement * moveSpeed;
speedDif = (targetSpeed - rb.velocity.x + platform.velocity.x) * currentAcceleration;
rb.AddForce(Vector2.right * speedDif);

this does not work perfectly

it's close but the player is still not in sync right

[languid spire]

Im not sure what the problem is here
Player lands on platform
-- Parent Player to Platform
-- RB kinematic = true
-- platform and player moves via transform
Player leaves Platform
-- Unparent Player from Platform
-- RB kinematic = false
-- Player moves via Rigidbody physics

[ionic topaz]

Okay turns out the higher the acceleration value the better I sync with the platforms movement

[trail heart]

Are you transferring the speed in collider contact or by proximity? Collider contact is a very uncertain metric that changes from frame to frame

That code there is doing something else than simply adding the platform's velocity to the player's velocity

You don't have to resolve everything into one AddForce call

Try adding player's forces first, then the platform speed with ForceMode.VelocityChange

[ionic topaz]

Yeah I found the code on a tutorial that I simplified greatly, but it works as it's own form of drag at the same time capping the max speed, very nifty

[ionic topaz]

this is Unity2D

I don't believe velocityChange is in 2D

[cosmic dagger]

nope, just force or impulse . . .

[ionic topaz]

I mean I can probably just up acceleration when standing on a platform and it'll work

I already change acceleration for when knockback happens

[trail heart]

Another option that comes to mind is to increase the friction of the platform a lot instead, if your player is controlled by forces anyway

Assuming the platform is also moving with forces/velocity

Also assuming your character isn't circular and rolling around

[ionic topaz]

Players physics material has 0 friction

[trail heart]

Having to assume a lot

[ionic topaz]

Player is square and walking like a champ

lol, sorry for not giving much info

I've made the platform now just use rb.velocity = "movement code here"

[trail heart]

You could call Rigidbody2D.MovePosition in FixedUpdate exactly as you might use Transform.Translate in Update

[ionic topaz]

I've done that too before

no difference between just setting velocity

but I'll do that

[trail heart]

The MovePosition needs to get the change of position of the platform since the last FixedUpdate to work right

If even that produces somehow weird results, something else must be going on

[ionic topaz]

nevermind

moveposition is bad

as child will not move with parent

[trail heart]

Maybe the way you're detecting the player to be on a platform is not working preciesly from frame to frame

[ionic topaz]

oh that's currently not an issue

for testing sake the player is always moving with the platform no matter what

Well I believe I have my solution with acceleration anyway now

Much appreaciate the help!

[frank zodiac]

why am i getting a red line

[burnt vapor]

You probably need to import the required namespace.

[cosmic dagger]

well, what does the error say? the context would help . . .

[frank zodiac]

when i do it gives me an error

Import the correct namespace

Probably Unity​Engine.​Input​System

[frank zodiac]

i did

[green ether]

Im pretty sure you need to setup your ide correctly, it should automatically add it or at least show you an option to import it

[cosmic dagger]

which namespace did you add?

[frank zodiac]

oh i see

check that your IDE is properly configured . . .

it should still work if you added it manually though

it didnt work

Does anyone have a good video/tutorial for a skill system? I’m trying to make it so after every wave I get the option of 3 skills to choose from

[ionic topaz]

While I'm here if someone can explain my code to me like I'm 3 years old that would help: float targetSpeed = xInput * moveSpeed; float speedDif = (targetSpeed - rb.velocity.x) * currentAcceleration; rb.AddForce(Vector2.right * speedDif); now I kinda of get the idea but I'd like to understand it better, my moveSpeed is set to 11.5, and when moving right the addforce seems to cap at 11.5 or -11.5 for moving left and when stopping I go back to 0 velocity as if there was drag even though there isn't any

[frank zodiac]

doesnt work

oh wait i need to install the input system from package manager

[green ether]

highly likely

What would be the best way to create an Animal crossing or Undertale style dialogue SFX?

Where there is a noise on each letter in the dialog, but each is a different pitch?

Part I can't figure out is having each noise a different pitch

[cosmic dagger]

change the pitch every time the noise is meant to play . . .

[rich adder]

use a IEnumerator to iterate each char

[cosmic dagger]

access the audio source playing the noise and change its pitch, i presume randomly . . .

If i’m setting up a levelmanager gameobject/script, what’s a general idea of everything that should be going in it? I’m creating a 2d castle defense game. Would it just be anything pertaining to that level that would clear outside of the level? Like stat increases/skills gained/monster stat changes throughout waves?

[rich adder]

we cannot tell you what your projects needs are, only you know this

generally, why would you have stats in a level manager though?

[untold hull]

I’m just wondering generally what a Levelmanager is used for, i’ve seen it in a couple tutorials just unsure of it’s use. I meant more so stat increases, like upon wave completion give +10 attack or something that only pertains to that level, or would those just still stay in their respective game objects

[rich adder]

there is no hard rule how to set up these things, its all relative. I would use a level manager to maybe store all my Level objects and maybe each one of those stores their own custom data, like maybe custom reward they give etc.

I would not check manually each level through a manager

I would just use the manager to store the array of my Level objects and that is what contains things like maybe Reward obj that can be stat increase, new weapon etc.

Scriptable Objects would probably be very handy here

[untold hull]

Gotcha, I think. I’ll just have to play around with it for it to make more sense lol

[tough cave]

how could I approach this problem? Maybe terms to google for? on how to make my sprite change layer priority based on if its infront of behind the 'desk'?

[buoyant knot]

Levelmanager is very vague

[buoyant knot]

i know Velvary’s youtube channel has a tutorial on this

i forget the name of the video/feature

https://youtu.be/rVBzTKvoStk?si=2oxwXdqKQN6apSmu

maybe this will be what you need

I'm making a rhythm game and I'm having trouble syncing up the music to the notes.
is there a way to sample how long the music (audio source) has been playing? I can't find it in the documentation.
right now I'm just using a float that I add time.fixedDeltaTime to in fixed update but that isn't a good way to keep track of it and is already causing problems.

[rich adder]

maybe use clip time and check where you are here
https://docs.unity3d.com/ScriptReference/AudioSource-time.html

[neon ivy]

damn... I guess I was very blind xD

didn't see .time in the documentation

thanks

[bold nova]

I am trying to create a universal object pooler. That object pooler class contains a list of my own class "Pool". It contains a List<Component>. The problem arises, when I try to instantiate game object with that component on it. and add to the the list. ObjectPooler gets some component as an argument

public static Component ProvideObject(Component component)
{
  GameObject newInstance = Instantiate(component.gameObject, position, rotation);

  pool.Instances.Add(newInstance.GetComponent<component.GetType()>); // add GO to the List<Component> of the pool class
}

This is the error I get :
Operator '<' cannot be applied to operands of type 'method group' and 'Type'.

[rich adder]

<component.GetType()> makes no sense

[bold nova]

yeah, that first thing that came to mind

[shadow rain]

hello so ive got a script for an object to point towards the mouse but its not pointing the way i want does anyone know how to fix this

[bold nova]

I just dont know how to pass a component in a method, instantiate a GO with that component and add that Go to a list of specific component

[rich adder]

you could do newInstance.GetComponent(component.GetType()) ig

[languid spire]

yeah, you need

GetComponent(typeOf(component));

[rich adder]

how to fix what? we don't even see the code

without code at very least, we are just guessing

[bold nova]

yeah, it worked, thanks😁

[shadow rain]

Sry I’ll send later

What's wrong with this list?

did you create a class named Enemy ?

[polar acorn]

What is Enemy

[hallow totem]

I don't know. :'3
I'm just following a tutorioal, though it was the name of the list, my bad.

[rich adder]

either tutorial is bad or you missed a step

should probably start with the basics of c# tbh like how to create a class etc

[final glade]

My game is a defense tower game between germs and tissues
Basically now I’ve designed a level but the issue is with the germs
The issue is there are 4 scripts and 2 objects/prefabs needed. 1 empty object with just the script to create a prefab in the scene to instantiate them in simpler words, another in assets below contains everything else. The issue is they don’t pass the rigid body 2d or any other scripts to the one in the scene although I made sure of it in the scripts any fixes?
The way i passed them is that I serializedfield everything I need in the one in the scene then I pass them to a parameterised function called InitializeObjects present in each of the other classes.

The other scripts as expected do not run because they’re not in the scene so how can I keep on calling the important functions in the other classes?

[storm pine]

Is there any way to get any inactive object by type through script?. I tried with FindAnyObjectByType but I found on the documentation that only works with active items. If there isn't any easy way my other option is to select it through the inspector using a variable

[hallow totem]

Would it have to refer to a class inside that script? If not maybe I just named it different on accident, if yes, well there isn't a class in that script before that list, in the tutorial I mean.

[polar acorn]

Does Physics2D.OverlapCircleAll require Rigidbodies on in-range colliders for them to be detected?

The player doesn't have a Weapon component

[hallow totem]

Yeah I moved the script, thanks.

Since you posted a screenshot of your Assets window with all your scripts I just want to make sure there is no doubt:
GetComponent does not look in your Assets but on the objects in your scene!

[brazen geyser]

Hello, I'm starting a project in Unity and when I press the space key it doesn't work and I can't find the error, in case someone could help me

Pass the code:

{
    public float speed;
    public float jumpForce;
    private Rigidbody2D rb;
    private float horizontalMovement;
    private bool grounded;

    private void Start()
    {
        // Obtener el componente Rigidbody2D del objeto
        rb = GetComponent<Rigidbody2D>();
    }

    private void Update()
    {
        // Capturar el movimiento horizontal del jugador
        horizontalMovement = Input.GetAxisRaw("Horizontal");

        if(Physics2D.Raycast(transform.position, Vector2.down, 0.1f))
        {
            grounded = true;
        }
        else grounded = false;

        if (Input.GetKeyDown(KeyCode.Space) && grounded)
        {
            Jump();
        }
    }

    private void Jump()
    {
        rb.AddForce(Vector2.up * jumpForce);
    }

    private void FixedUpdate()
    {
        // Actualizar la velocidad del Rigidbody2D en el eje horizontal
        rb.velocity = new Vector2(horizontalMovement, rb.velocity.y);
    }
}```

[rich adder]

try rb.AddForce(Vector2.up * jumpForce, ForceMode2D.Impulse);

also make sure your grounded is working

this can literally be
grounded = Physics2D.Raycast(transform.position, Vector2.down, 0.1f)

[brazen geyser]

Thank you very much <3

[rich adder]

is working now?

[brazen geyser]

Yep

[rich adder]

nice

[frank zodiac]

my functions arent showing

[rich adder]

try adding the object with the actual script

not the script from project folder

[frank zodiac]

ic ic

ok ill try that and let u know how it goes

it works!

tysm :)

[rich adder]

[plush hound]

For some reason, Physics2D.OverlapCircleAll isn't returning all the colliders expected. Any ideas why? I have a Rigidbody on the GO calling the function, but no Rigidbodies on the expected colliders. I'm specifying a LayerMask, and I assigned all the expected colliders the layer in question.

[frank zodiac]

wait guys how can i make a tilemap have a layer for ground so that the player can stand on it, because my player just falls through

[short hazel]

Make sure you passed a layer mask and not a single layer number. These are different. You should post the code

[plush hound]

https://gdl.space/mekavayake.cs

I'm pretty sure I passed a LayerMask

[short hazel]

Yes the call is correct

[plush hound]

It's odd because it's recognizing something definitely outside its range without recognizing anything within

And then after some time the function actually starts returning stuff

[short hazel]

The mask includes the selected layers in the results, maybe you have it inverted?

[plush hound]

Yes, I only want the Germs layer

[frank zodiac]

how do i fix this

[short hazel]

Your resolution must be composed of even numbers only. 1469 is not an even number. Change the resolution to fix the problem

[frank zodiac]

i know but where do i change the res?

do i put 16:9 aspect?

[short hazel]

Are you in the Editor right now?

Should be at the top of the Game View

By default it's set to "Free Aspect" so it takes all the room you give it when resizing the tab

[frank zodiac]

ah i see okay then

also what do i set this value to

in the pixel perfect camera componenent

[short hazel]

No idea, see the documentation, maybe it has some tips about this

[real falcon]

how is this possible? do I not understand Vector3.Dot? it should be 1, shouldn't it? since both vectors are normalized?

[frank zodiac]

ok

[real falcon]

it seems to change as velocity decreases even though the DIRECTION isn't changing

[short hazel]

A vector is 2 (or 3) numbers, you need to print those instead of whatever these first two numbers are (magnitudes?)
A normalized vector will always have a magnitude of 1, wherever it's pointing at

[frank zodiac]

i still dont get it, does it mean my monitors resolution or my pixel arts resolution or what

my pixel art is in 32px

[woeful terrace]

Hi, I'm just trying to set up my visual studio as it was before. I had the minimap and I zoomed in a bit but I can't figure out how to do those simple things for the life of me.

These are the only ones I can really find and none of them works
View > Appearance > Zoom In (Ctrl+=)
click View. Click Appearance. Click Minimap.

Issue is I have no appearance when I click view. I apprechiate nay help (Not quite the toppic of the channel but I need help and this is the best fit I can find lol)

[short hazel]

Try out some values and see what it looks like. Ask in #💻┃unity-talk if you have more issues, it's out of scope for this channel

[frank zodiac]

ok then

[short hazel]

What are you referring to by "Minimap"? Is that the feature you can enable on the scroll bar which shows a zoomed out version of the code? Or maybe sticky scroll which keeps the innermost scopes at the top of the code editor?

[woeful terrace]

Yes the zoomed out version on the side

[short hazel]

If I remember correctly it's under the Text Editor > Scroll item

Checking...

Text Editor > [programming language] > Scroll Bars
"Use map mode for vertical scroll bar"

[woeful terrace]

Ah thank you very much

Do you know about the zoom however?

[short hazel]

Zoom will be at the bottom left of the code window when you have a file open

You can also Ctrl + Scroll Wheel while over your code to zoom in/out

[woeful terrace]

Yes there we go thank you very much 👍

Hi, so bassicaly I have a script that I tought would check for name of the gameobject that its attached to and if its the same it will just print out a message in console but its not why? https://hatebin.com/zfgkuzaplo

the way they are being Instantiated https://hatebin.com/sdhfssvcti

[eager wolf]

why does this code break unity?

When i try to debug this manually, it shows me that the "coordsVisited" literally equals to "uhOh" how is that even possible?

[short hazel]

There seems to be a suggestion under uhOh in the while loop condition (see: 3 gray dots under the variable name). What does it suggest?

[rich adder]

can you show which index number part

[short hazel]

Make sure you saved, and that you were not in play mode while editing the code

[rich adder]

would strongly advise against using GameObject.FInd or any method checking strings like that

use the Type safety aspects to your advatage

[languid spire]

if they are float values you are looking at float inaccuracy

[eager wolf]

yeah, the error is normal, the game tries to access an array with index -1 😩🤯
so this "while" is mean't to stop that from happening

[eager wolf]

int

[short hazel]

You need to be looking at the Hierarchy tab while the game runs, not in your Assets. Instantiate() adds a "(clone)" postfix to instantiated object names.
A prefab named "Sample" will be "Sample (clone)" when instantiated. Doing logic on object names is a terrible idea though.

[eager wolf]

Look, i just changed it to another number that is predictable. Every time my maze is done generating, this number will go to -1.

And EVEN THIS breaks the game

[knotty ferry]

need help how to make when A game Over screen pops up and the player coudn't use controls walk when player IsDead = true;

[blissful spindle]

I see, the problem is that I dont know how else do I get the GameObject except with .Find

[rich adder]

at very least there is FindObjectOfType /FindFirstObjectByType for runtime finds

[blissful spindle]

OOOHHH you are right! thx wow 👍

[short hazel]

Your logs looks the same each time (2 numbers separated with a space). Are you sure the log is originating from the place you think it is? Add some other text so you can tell the differences between them.
Debug.Log($"Log from some place {uhOh} {coordsVisited}")

[blissful spindle]

hmm will look it up thx

[eager wolf]

yes it is, i'm amazed

[eager wolf]

is there some alternative to using "while"

it just hates me today

[rich adder]

GameObject.SetActive and show the screen ?

[knotty ferry]

the GameObject.SetActive is already active when player Dies it pops up but the play could still use controls like walk

[blissful spindle]

Oh, I get it so I dont need to look for an object like I did so far which was
GameObject playerObject = GameObject.Find("PLAYER");
Player playerScript = playerObject.GetComponent<Player>();
but now I can just find the script instantly(correct me if I am wrong please)

[short hazel]

35 < 35 is false. It's not about the while, something else is going on.
Start by changing the contents of the logs so you can tell which is which.

[rich adder]

yeah but do note it only finds the First one usually

not a good way if you have multiple different objects with same script

[blissful spindle]

oh, well thx! it helped a lot 😄

[blissful spindle]

got ya

[blissful spindle]

will keep that in mind

[languid spire]

it's not the while, so far you have shown no code that could throw that exception

[frank zodiac]

how do i import fonts into unity? do i import the .ttf file or the .fon file?

[languid spire]

ttf

[frank zodiac]

oh wrong channel

[eager wolf]

then how is it possible?

[frank zodiac]

but thank you anyways

[languid spire]

show the code throwing the error

[rich adder]

https://unity.huh.how/references/simple-dependency-injection
this is also IMO one very good way to do most everything
but yeah in code-beginner dont worry so much lol
just know these options are there , and beneficial in long run

[frank zodiac]

it still doesnt show up on the textmeshpro

[blissful spindle]

ye, thanks I really do want to be a full time indie game developer one day so learning this is going to be helpful lol

[languid spire]

no, you need to conver the ttf to tmp, there is a menu option for that

[frank zodiac]

ah i see

thank you

[frank zodiac]

i cant seem to find it, whats it called

[eager wolf]

this code somehow runs, but gives an error

[eager wolf]

BUT, if i change it to this, it breaks

[polar acorn]

Show the full error

[languid spire]

that is NOT the code throwing the exception

[digital wharf]

I am trying to make the player's y rotation be the same as the camera's y rotation but the rotation keeps returning as a number between -1 and 1 ```
//relevant code
//cameraRot is a temporary var I am using to debug
public Transform cameraRotation;
public float cameraRot;

cameraRot = cameraRotation.rotation.y;

[wintry quarry]

Your error message contains the filename and line number of the error. Read it

[wintry quarry]

You're trying to read quaternion components. Don't do that

That's not how Quaternions work

[polar acorn]

Yes, because a Quarternion is a 4D normalized value that can only be between -1 and 1

[digital wharf]

got it

[eager wolf]

I already explained it. It's an array that's being indexed with "-1" and obviously that doesn't exist, so it gives me an error

the "while" loop is meant to stop before the array is indexed with -1

[wintry quarry]

Maybe show that actual code though

[polar acorn]

And since we don't have any other code that shows where it's being used we can only assume you've set it to -1 the line right before this so perhaps try not doing that

[eager wolf]

yes, but that only happens if "coordsVisited = uhOh"

which is why, my "while" loop is meant to run "coordsVisited < uhOh" but that breaks

[short hazel]

What's the motto again? About causality

[languid spire]

then why does your for loop test for <= ?

[short hazel]

Maybe it's entirely unrelated lol

[eager wolf]

I also tried "solutionNum > 0" and that broke

[eager wolf]

because this is how I debuged, if i change it, unity crashes

[polar acorn]

And we're just supposed to divine that from tea leaves or what? You haven't shown any code that changes solutionNum

[wintry quarry]

Not if you change it after that check, e.g. inside Move

Which you MUST be doing else you'd freeze

[eager wolf]

right, but the uhOh already takes that into consideration

[wintry quarry]

How?

[polar acorn]

just post the fucking code man

[wintry quarry]

That's not possible since clearly all this other code is inside Move

[short hazel]

Remember, we are not in front of your screen!!!!

We cannot see everyhting you see

[eager wolf]

bro it's 600 lines of code, do you want to read 600 lines of code? I'll gladly send it if you want to

[wintry quarry]

Neither your loop nor your "uh oh" thing can affect anything inside Move

[polar acorn]

Absolutely. Just make sure to read !code for how

Yea

That's nothing bud

I really don't want to play whackamole

[rich adder]

hah meere bag of shells.. try 4-5k ones

[wintry quarry]

Reading code isn't like reading a novel. We know how to skim through extremely quickly

[eager wolf]

actually, you might be right lol

[eager wolf]

HAHAHAAHAH I JUST TESTED THIS AND YOU'RE 100% RIGHT LMFAO

it's the code right after that's actually causing the crash (in the start())

sorry guys

i guess the error in the "while' was stopping the other code from running

[polar acorn]

Okay, so, now that you've actually posted the code, solutionNum is literally never set to anything in this code. All you do is increment it in this script. So, a different script, or the editor, is setting it to -1

[frank zodiac]

why is there a red line

[polar acorn]

What's the error say

[frank zodiac]

that its not defined

[slender nymph]

use the quick actions to add the correct using directive

[short hazel]

Missing using directive at the top. Put your mouse over it and click the light bulb icon

[polar acorn]

Does it offer any suggestions for solutions

[frank zodiac]

ok thanks!

[languid spire]

Also, wtf is the point of the while loop in Move() ? It's only ever executed once

[eager wolf]

no, it's executed like 200 times lol

[languid spire]

no it is not.
while (a==0)
and every case in the switch sets a=1

[polar acorn]

How? Every case sets a to 1

Also, if a can only ever be 0 or 1, why is it an int

[eager wolf]

because it gives 1 output every time.

[polar acorn]

Meaning that the next time it hits the loop, a is no longer 0 and it doesn't run again

[short hazel]

Move is itself executed 200 times, but each time the loop runs once

[polar acorn]

meaning the loop runs one time

which means why is there a loop

[languid spire]

some of the shittiest logic I have ever seen, sorry to be blunt

[eager wolf]

yes

i 100% agree

i don't know how to code an efficient maze algorithm

this code was also written 2 years ago... i'm reworking it right now haha

[short hazel]

It's the easter egg that crashes the game if a cosmic ray hits and flips the bit at the memory location of that variable

[languid spire]

take my advice, throw it all away and start again from scratch. 'You cannot make a silk purse from a sows ear'

[short hazel]

If it's a simple 2d maze, you can look into recursive backtracking algorithms for carving through the walls randomly

[frank zodiac]

im trying to drag this text into this slot but its not working

[slender nymph]

that's the wrong variable type. TextMeshPro is the 3d version. use either TextMeshProUGUI or TMP_Text which it inherits from

also don't crosspost

[frank zodiac]

oh i see, thank you sm

[frank zodiac]

ok

[short hazel]

Well it would also work for any number of dimensions greater than 1, it would be a matter of changing which sides are accessible

[real falcon]

hm ok so I realized the problem with my previous code and now I am trying to get a value which essentially gives you a "simplified velocity" based on your actual difference in location between ticks

locationBasedVel = (transform.position - previousLocation) * Time.deltaTime;

I don't think multiplying by deltatime is correct though

should it be divided by it?

but then what if it's zero? I know that SHOULD be physically impossible but I want to account for it, knowing how code often works

I guess I need to take the magnitude of that vector as well, but regardless

[eager wolf]

this breaks my script, it previously worked, so idk why it does that. It's called on start()

https://hastebin.com/share/ametaqazaz.java

[wintry quarry]

Yes you should be dividing.

[wintry quarry]

That will happen only when time scale is 0

In which case it makes sense because that means you're moving nonzero distance in zero time which implies... nonsense

[real falcon]

my solution is to just keep the current velocity if it ends up as zero

[vestal ether]

If you knwo C# at a intermediate level will u be able to create games in unity proficiently

or does unity have extra stuff u have to learn when using C# when u create the game's stuff

[real falcon]

I would say it has a lot of "extra stuff" from my own expirience because while programming is pure logic, Unity is a game engine that has to work in a specific way due to technical limitations, and so you need to know how actual game engine stuff works

@wintry quarry my code seems to be spitting out nonsense unfortunately, do you see any problems here? or could it be the fact that I'm messing with the time scale?

nah it seems to be nonsense even when timescale is 1

[wintry quarry]

What is it spitting out and why is that nonsensical?

also where and when is previousLocation set?

and where is this code running

[real falcon]

I'm running in a straight line, but it seems to increase for a bit and then almost loop back to zero. that or it sometimes randomly goes low

this is called from Update, before the code that moves the collider

[wintry quarry]

Does this give you anything different?

float distance = Vector3.Distance(transform.position, previousLocation);
float speed = distance / Time.deltaTime;
print($"Speed is {speed}");```

also if you want the vector velocity you can do:

Vector3 diff = transform.position - previousLocation;
Vector3 velocity = diff / Time.deltaTime;``` no need for the magnitude aqnd normalization etc

[real falcon]

no, it appears to still randomly go low and high

my movement code is otherwise working, I can run in a line and accelerate fine etc.

[wintry quarry]

where is this code running

[real falcon]

UpdateGhost is called from Update

[wintry quarry]

also how is the object moving?

[wintry quarry]

Is it Rigidbody motion?

[real falcon]

character controller

[wintry quarry]

Ok that might be the problem I think...

What happens if you do this code in FixedUpdate?

[real falcon]

I could try it, though I didn't do it there because I figured that was for the physics system. also, should I then remove the delta time? or just copy it as is

pasted as is, it seems to randomly zero out sometimes

instead of going low it will just go to zero

and then jump back up to a more reasonable speed

[wintry quarry]

ok FixedUpdate isn't right then

[wintry quarry]

where does playerVelocity come from here?

how is it being calculated

[real falcon]

ground move and jump move basically calculate it with the input vector and friction

playerVelocity seems fine, it makes sense to me and it works as intended

[wintry quarry]

friction?

[real falcon]

the only reason I'm not using it is primarily because it has a negative up component usually since the character controller seems to need that in order to stay grounded

[wintry quarry]

Also if you have this playerVelocity variable already why not use it

[real falcon]

so you can stand on the ground and be still, yet the AI thinks you are moving downwards

[wintry quarry]

So why not just use this one

[real falcon]

because I do want the AI to be able to respond to jumping or falling

[wintry quarry]

You can also try this:

characterController.Move(...);
Vector3 velocity = characterController.velocity;```

[real falcon]

I wanted to just have a velocity which was based on actual position change, not the internal one that has to account for the nature of collisions and charcater controller and all that

[real falcon]

hmm ill try it

so does the character controller velocity basically get like clamped by move?

[wintry quarry]

Yeah it tells you how much it actually moved

not sure if it needs / Time.deltaTime or not

[real falcon]

awesome I think that works

no idea that existed, super helpful tbh

[violet glacier]

For a 2d game, is damage popup better as UI or regular component? I will instantiate a lot of damage popups at once

[eager wolf]

anyone got any insight on this?

[cosmic dagger]

Both work fine, just make sure set upetup the UI correctly. Keep everything on the same canvas to maintain a single draw call. Either way, use object pooling to avoid any hiccups in performance . . .

[violet glacier]

Thanks, just to clarify for the canvas, do (1) I keep all damage popups in one Canvas (e.g. DamageCanvas) and UI in another canvas (thus having 2 canvas) OR (2) having one UI canvas and make the damage popups the child of a parent inside the canvas? Did you mean (1) or (2)?

Either will work. You can have a canvas GameObject as a child of another main canvas GameObject or both objects as separate siblings. As long as it's on a separate canvas, it'll have its draw call . . .

How do I make a countdown system?

Or anything that counts time and triggers an action at the end of the time

[slender nymph]

create a float and subtract deltaTime from it in Update

[ivory bobcat]

With a self implemented timer, coroutine or invoke.

[ivory bobcat]

Self implemented timer:cs private void Update() { if(Time.time > next) { //Do something next += delay; } }Coroutine: https://docs.unity3d.com/ScriptReference/Coroutine.htmlcs private void Start() => StartCoroutine(Countdown(action, delay)); IEnumerator Countdown(Action action, float delay) { var next = new WaitForSeconds(delay); while(true) { yield return next; //Do something } }Invoke Repeating: https://docs.unity3d.com/ScriptReference/MonoBehaviour.InvokeRepeating.html```cs
InvokeRepeating("DoSomething", delay, delay);

> Invoke and InvokeRepeating do not stop after the game object is deactivated. On the other hand, this not true for coroutines. They stop after the game object is deactivated or destroyed.
A self implemented timer might be fine if you're simply expecting it to run once.

[sterile kelp]

hey uh, if one were to come across a file with a .bytes extension, how would one convert it to something humanly readable?

[slender nymph]

it depends on what the contents of that file actually are

[sterile kelp]

a text file

i mean just text

methinks?

[slender nymph]

i'm gonna go out on a limb and guess you've got a save file for some other game and you want to read it. but doing so will depend on how it was serialized

this is also not the place to get help with modding other people's games, it is a development server to help with ones own unity projects

[glossy blaze]

is there a runtime fee

[deft grail]

there is no fees for using Unity

[glossy blaze]

cool

[teal viper]

There is a "runtime fee"(which is applied under certain conditions), but it sounds like you're asking about something else judging from the context.

[gentle stratus]

whats the easiest way to check line of sight between two objects

i was thinking raycast but that only returns bools and itd return true regardless of whether or not theres a wall in between the two objects

[slender nymph]

raycast and check what was hit

[gentle stratus]

oh can i do that

i didnt see a method for checking collider

[slender nymph]

just compare tag or check for a specific type of component on the hit object

[gentle stratus]

ok thanks

Im trying to create a rope swinging script, to do this I am connecting the player to the rope with a hingejoint and setting the collided object with the same velocity as the player, but when the player connects, they hit the link of the rope and just stop all velocity. Does anyone have an idea to get around this? I tried making the rope istrigger on collision but its a bit janky when I do it that way. Code is Above

sorry for block of code :/

hi, i'm making a player controller with a rigidbody, but whenever i move into a wall my character just stops
here's my code: https://bpa.st/OOEA

i did try to use a constantforce but the force would keep increasing infinitely and become too fast

basically, how do i move a rigidbody with input without directly setting the velocity

(so it's smooth and stuff as well)

you have to manually write sliding angles code or maybe try diff material. Character controller already has it built in

have you tried drawing the raycast ?

use Debug.DrawRay, with the same values

[lunar apex]

question: I am trying to make something that can detect if the players head would be inside of roof if they uncrouched and if it would then the player should not uncrouch. I do not understand what is going wrong. If you need more context in code I can give it to you:

sorry i deleted my old question so I added it back

alr ill try it

[rich adder]

also I would not scale the entire object, I would just scale collider

[lunar apex]

you mean like this ``` if (Debug.DrawRay(transform.position, Vector3.up, out hit, headCheckDistance + 0.3f))
{
return false;
}

[rich adder]

DrawRay only need start pos,dir*maxLength. Thwew is no out or if statemnt, the point is to see how your physics ray is in the scene
look at the method signature, the rest has default params

[opaque hinge]

I am trying to use Unity's rule tiles and tile map system. I generated a grid of rule tiles, and I added a bool isBlocked. The problem I am encountering is that each rule tile that is generated follows the same script, so if I mark isBlocked as true, it is true for every tile. Is there a way around this using rule tiles, or would it be better to just generate the grid using gameObjects that can be individually scripted

[abstract finch]

Is there a way to share a float between two classes without them having to reference each other? I want float mouseSensitivity to be used in the camera and charactercontroller class. When either class modifies this value both will be affected by it

[teal viper]

If you wrap it in a reference type.

[abstract finch]

Something like a struct or class?

[teal viper]

Struct is a value type

[abstract finch]

so the latter something like MouseValues with a float called mouse sensitivity in it?

[teal viper]

Yes. Though, you'd still need to pass an instance of it to both of your classes. For that either one of them would need to reference the other, or a class higher up the logical hierarchy would need to create and pass it to both.

[abstract finch]

I see, I've done this before so its not an issue for me

thanks ill go with that

i was wondering also about using a public static float, is this a viable method of doing it?

public static float mouseSensitivity= 3.14f;

[hallow totem]

Why is the text so smudgy? Is it the font size?

[fair veldt]

try increasing the font size and scale down the textbox with the scale tool

[summer stump]

Not exactly the issue, but don't use free aspect, and set your game view scale to 1 (not 1.1)

[hallow totem]

I think there's only so far that could get me, it's better but still not great and this is font size 1000.

Okay the rest of the issue was the free aspect and view scale, my bad, thanks.

[blissful spindle]

Hi, is there any way of referencing a script that is attached to a prefab, so for example I want to increase the drop of my experience on killing an enemy but the enemy is a prefab so I cant find it in my game scene. How would I reference it?

[slender nymph]

wait, if you want to do this on killing an enemy, why do you need to reference the enemy prefab?

[blissful spindle]

well just the script cus I have a OnDestroy void that plays my addExperience in PlayerScript

[frank zodiac]

i know this is unrelated but why dont you use the new input system

[slender nymph]

which script

[blissful spindle]

I will send you both

[slender nymph]

are you trying to reference a component on the Enemy from the Player or are you trying to reference something on the Player from the Enemy?

[blissful spindle]

enemy: https://hatebin.com/llehynunok
player: https://hatebin.com/mqbnvqbmgi

[slender nymph]

you know you could have just answered my question instead of dropping those links and i could have provided the answer to your issue

[blissful spindle]

well I want to have an upgrade which takes the enemy script and increases the addExperience in enemy Script but its on a prefab so how can I acces it

[slender nymph]

you don't. you instead reference whatever spawns the enemy objects. and have that object tell the prefabs how much experience to drop whenever it spawns them

[blissful spindle]

oh, I see

[green ether]

except for when you upgrades are changing

[blissful spindle]

got ya, thx

[green ether]

When you can get it after enemies already spawned/ as an equippable that you can equip/ unequip

You would want a different solution

[blissful spindle]

well, its like in vampire survivors you just get it while the enemies are spawned

[green ether]

Then i guess its not too noticable?

[blissful spindle]

oh, I think it could be better if I make a new float that just times the experience in my player script lol am dumb 😄

[green ether]

But could be weird if you get the upgrade and dont feel the effects straight away

Like: You upgrade xp gain but dont actually get more from all the enemies who are already spawned

[blissful spindle]

well the intention is to get it right from the point you get it YK

[green ether]

yeah exactly

[slender nymph]

the spawner object can also keep track of what it has spawed and tell those objects too

so either way you shouldn't be modifying the prefab itself

[blissful spindle]

yes, but I think it would be too complicated for me as of now

[rapid pendant]

Hey everyone, just joined here. I have a MERN Stack background. Now, I am shifting to XR. I am aware of fundamental tools like Unity, Unreal, Lens builder, SparkAr, Blender, C#.

But I am looking for some learning resources in XR to start off.

[blissful spindle]

but, its definitely a good solution since it can keep track of everything

[slender nymph]

modifying the prefab is going to have unintentional consequences that are even more complicated to figure out

[blissful spindle]

ye, I have ran into thos issue in the past

[slender nymph]

check the pinned documentation in #🥽┃virtual-reality and/or #🤯┃augmented-reality

[blissful spindle]

well, anyways thx for helping me guys

[hallow totem]

How can I get this

to show up on top of this?

They're on the same canvas.

this is a code channel

[fair veldt]

have you tried putting the text above the image in the hierarchy

[modest dust]

Or rather below

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/UICanvas.html

Read about the draw order

And yeah, for future notice, this is a code channel, so at least go to #💻┃unity-talk or search for a more appropriate channel, such as #📲┃ui-ux

I wanted to reuse an animation for another game object so I ctrl c and ctrl v, put it into the animator controller of new object, but then it broke all the other transitions, anyone know why or how i can fix this? When I delete the animation in the controller, it went back to normal

this is a code channel. but just drag the animation clip into the animator controller from the assets folder, don't bother with copy/pasting the clip from one controller to another

[molten dock]

how would i have a navmesh agent randomly choose to go to fight one of four targets

[frank zodiac]

i have the same issue, lmk if you found a solution

[hallow totem]

Sorry, I haven't looked through channels thoroughly and sicne I'm a begginer I gravited to this one, my bad.

[hallow totem]

I increased the font size and decreased the scale.

[topaz mortar]

is it common to define lists or dictionaries as var? why?
var itemsToRemove = new List<int>();

[frank zodiac]

the scale of the text box?

[deft grail]

you can do anything as var not just lists
its just personal preference mostly or for speed that people use it

[deft grail]

add the enemies to an array then get a random number using Random.Range and pick an enemy from the array

[hallow totem]

Yeah the x and y is 0.05, like on the screenshot.

[frank zodiac]

oh i see, thanks

[topaz mortar]

so it's totally fine to define it as var?

[deft grail]

var means basically it will automatically pick the appropriate variable type instead of you having to manually do it
var something = 0; would make something an int
var something = new GameObject[]; would make something an array of GameObjects
Just saves you time by trying to define the type yourself

[topaz mortar]

yeah I understand what it does, I'm asking if it's good practice to do it

[deft grail]

doesnt matter really i think,
its easier at a quick glance for someone to tell what it is if you dont write var, otherwise its just preference both work fine

you are working on a COPY not the original

[oak fulcrum]

Hi, I literally just started with learning Unity. I'm following a tutorial and just wrote my first script (copied it exactly from the video) but I got an error and am unable to see the ''Move Speed'' bar that he has in his tutorial. I also get an error that says ''Assets\Script\PlayerControl.cs(17,40): error CS1012: Too many characters in character literal''. I'd appreciate it a lot if someone could help me!

First picture is from the video, second is mine, third is the script.

[deft grail]

screenshot the error please

[knotty gust]

yhhh i figured it out now

[knotty gust]

had to set an index for the struct and reference that in the update

thanks tho

[deft grail]

you have a problem with your input lines

specifically the part in brackets ()

check the tutorial and make sure its 100% same (its not)

[languid spire]

yep, with structs better to use for rather than foreach

[languid spire]

Hint ' is not the same as "

[oak fulcrum]

Yeah looking back I thought that might've been it, but I tried doing '' and it just took it as ' ' instead (two ' seperate)

Wait

No I think I might got it

Yes I got it!

Thanks!

[rotund egret]

How do i make an object To destroy its own self only its self after it hits a specific thing?

[deft grail]

use a OnCollisionEnter/OnTriggerEnter then use Destroy(gameObject);

and for specific thing you can check the tag/layer of the thing you collide with

[rotund egret]

i did this

[deft grail]

that should work, but you should check the tag with .CompareTag("tag") instead of checking the name

[rotund egret]

wdym?

[deft grail]

you need a Rigidbody2D and a Collider2D with isTrigger selected on one of the objects

[rotund egret]

huh

[deft grail]

collider.CompareTag("YourTag")

[rotund egret]

like this ?

[deft grail]

yeah, just make sure you actually have the tag Energy_Ball on the object you want to collide with

[strong wren]

How do i hide TextMeshPro?

like in code

cause i cant just do

[rotund egret]

let me see if it works

[deft grail]

just disable the object

[strong wren]

SetActive(); doenst work on 2d stuff

[deft grail]

huh

it works on all GameObjects

[strong wren]

i beg to differ

[deft grail]

you are trying to disable the text itself, disable the object instead

[strong wren]

what object are you tlaking about tho?

you mean the Renderer

[deft grail]

the one with the text

[strong wren]

huh?

[strong wren]

thats the object with the Text

[deft grail]

no, you are trying to disable the text component

[strong wren]

ph

oh

i need to make a gameobject for it right?

[deft grail]

which you can do by .enabled

[rotund egret]

Here is a video of my issue

The thing dident work

[deft grail]

you can either make the variable of type GameObject or access the .gameObject of your text component

[rotund egret]

and yes ik im very messy

im still a beginner

[deft grail]

how are you moving the ball?

[burnt vapor]

Set the alpha to 0 I guess

Of the text

[rotund egret]

With Q E W S

Dont ask Why

Up W Down S Right E left Q

[patent compass]

I think he meant in script

[rotund egret]

it shows in the script tho i think

[deft grail]

yeah but how, with a rigidbody? setting the position? how

[rotund egret]

Using transform

[deft grail]

then that could be why its not working, try using a Rigidbody to move

[rotund egret]

aw man lemme try

[strong wren]

Countdown.SetText("Wave " + WaveCounter + " Starts In " + RoundDelay.ToString("0")); hey guys does anyone know why when i start the game the spaces inbeetween get removed?

instead of beaing Wave 1 Starts in 10

its Wave1Startsin10

[rotund egret]

Nope still dient work

[deft grail]

https://unity.huh.how/physics-messages

[storm pine]

If you use SetText you have to use it this way: http://digitalnativestudios.com/textmeshpro/docs/ScriptReference/TextMeshPro-SetText.html
If you want to use concatenating you can try with Countdown.text = "Wave " + WaveCounter + " Starts In " + RoundDelay.ToString("0");

[rotund egret]

Im having issues with the collogeon and destorying not the physics

idc about the balls movment

[deft grail]

OnTriggerEnter2D uses physics

so you do care about physics

[strong wren]

is there a better way?

Countdown.text = WaveCounter.ToString("Wave " + WaveCounter + " Starts In " + RoundDelay.ToString("0")); like this?

[deft grail]

and the movement of it affects if it collides or not

[storm pine]

Yep, or like this if you want to use the SetText() :

Countdown.SetText("Wave {0} Strats in {1:1} ", WaveCounter, RoundDelay); //{1:1} means you want the roundDelay with 1 decimal in case it's a float for example

Both ways are valid

[hexed terrace]

Or this more readable way
Countdown.SetText($"Wave {WaveCount} Starts In {RoundDelay}");

[storm pine]

sorry I have just see that fast, you don't need to do the ToString(), just your text

[strong wren]

i need the toString(). so it wont show me the decimals of the countdown

[storm pine]

I mean the WaveCounter.ToString, just Countdown.text = "Wave " + WaveCounter + " Starts In " + RoundDelay.ToString("0");

    {
        if (GameManager.instance.battleActive && !battleLoading)
        {
            battleLoading = true;
            GameManager.instance.battleStarter = gameObject;

            StaticBattleEnemys.rewardItem = rewardItem;
            StartCoroutine(LoadBattle());
        }
    }``` Hi i have a battle starter script and im making a ref to a game object in my gamemanager ``` public GameObject battleStarter;``` but when i enter a new scene some times its there and some times its not, my game manager is DDOL.

ok in the hierachy if i select another game object that also seems to make the ref becoming missing also.

[rich adder]

if your reference is on a DDOL into another scene, if ur switching scenes that object gets destroyed unless you dont unload the scene

[honest haven]

Thanks i think i was taking to you yesterday you said this would be a good way to store a ref of a game object.

[languid spire]

I must say this code looks very odd to have in Update

[honest haven]

yh its temp

[rich adder]

right but you said you were adding the new additive scene, I assumed you werent destroying the old scene

[honest haven]

yh i am destroying the old one

[rich adder]

thats whats breaking it

[languid spire]

well, thats why you lose references to objects in the destroyed scene

[honest haven]

so the top scene is never destroyed that just holds things instead of using ddol. then the scene underneath is the scene that im swapping out but also hods that game object

[languid spire]

tbh I would expect code like this to be in a delegate to onSceneLoaded so that any lost references could be fixed up using the newly loaded scene

[honest haven]

thanks i will fix that

i am just trrying to get this to work then i will refactor as my scene loading is hard coded too at the momnent

[rich adder]

I was thinking
Encounter Enemy , Store enemy , Load New Scene Additive, find out if player destroyed enemy, when going back to "old" scene destroy enemy

[honest haven]

yes so that is what im trying to do. i seem to have that all in place apart from 'Store enemy'

but other then SO i dont no what else to do. and if i have 10 NPCs that would be 10 SO
seems messy

like you said yesterday

[rich adder]

Shouldn't be a problem you can store a whole array.
How would you do encounter with 10 enemies in the first place anyway?

[honest haven]

its a shame static does hold gameobject refs

[rich adder]

I mean, you can store it in a static.. its just going to have the same issue

[honest haven]

each enemey has a battle starter class thats linked to static that holds some stuff but not the ref

{
    public static List<GameObject> enemies = new List<GameObject>();

    public static GameObject SplashScreen;
    
    public static int rewardEXP;

    public static Transform playerPosition;

    public static GameObject rewardItem;

    public static void ClearEnemies()
    {
        enemies.Clear();
    }
}```

enemies are not the same as the ref

[rich adder]

why is everything static

dont you have a singleton ? use that

[weak grove]

how is the object inspector and the C# code for an object related? am a noob, what is the object inspector showing me ? all the variables in the C# code?

[rich adder]

its showing you all the serialized fields

[weak grove]

fields are variables right ?

[rich adder]

yes

[honest haven]

So the enemies are prefab battle chars not npc enemeies. splash screen is just a splash screen each npc has there own. reward EXP is an amount you get when you win. rewardItem is the item the npc drops when they lose they are all attached to the npc

[rich adder]

public or [SerializeField] private are shown in inspector

[weak grove]

@rich adder ty 😄

am on day 2 of learning haha

[rich adder]

major thing is , Unity cannot serialize Properties so if you use those and don't see them in the inspector. That is why

[weak grove]

ah i see

[rich adder]

a prop is for eg public string HelloWorldText {get; set;} = "HelloWorld"

[weak grove]

ah ok ty

back to unity 😄

[rich adder]

I know what they are, i just dont understand why its static tbh

anyway back to the issue, if you do one encounter of 10 enemies, how do you plan on doing that

[honest haven]

So just to be clear becuase maybe singletons are not clear to me. i thought that they can be only used on things like gamemanager, player etc... because there is only one of them. So becuase there can be 10 npc's. i thought that singleton would be bad pratice am i wrong?

[rich adder]

well yeah you wouldn't want to have each NPC be singleton

anything you do in StaticBattleEnemys has to be reset manually

static will not change/reset through scene changes

[honest haven]

yes thats what i was going to do. again i can only go off what others have said to me in the past

my first original question was how can i pass data between scence somebody said use static

so i did that then got to the point ref didnt work. and now im here with that one

[rich adder]

well I wouldnt have suggested a static

I would've suggested a DDOL

[honest haven]

no it was not you

[rich adder]

yes because you keep destorying the scene that reference is in

[languid spire]

would not have made any difference, gameobjects which are not passed from scene to scene would still lose their references

[rich adder]

unless you bring the enemy with you on the DDOL

but you should be fine if you just dont unload the scene tbh

[honest haven]

see i also tried a ddol at one time and it did not work, but it was not a singleton

im not sure if they have to be

[languid spire]

you can also move scene for gameobjects if you use additive loading, no need for ddol

[rich adder]

yes that was the original thought

[honest haven]

ohh you mean pass the game object before a scene is loaded

[rich adder]

you said you were loading batle scene additive so I have no idea why you unloaded old scene

[languid spire]

no, load the new scene additively, move the gameobject(s) from the old scene to the new one, destroy the old scene

[rich adder]

they need to go back to old scene thats why

think Pokemon battle scene

[honest haven]

ok so fen told me about additve scene loading so i went down that road but if you unload a scene you destroy it. But then i thought it would be harder to not ref every object to deativate them

[rich adder]

you dont really need any references from the Addtive scene itself though

just maybe some bools to tell if the enemy that came with you was killed or whatever

[honest haven]

So if i didnt do what steve said and move the object. How do i deacive the scene with out destroying it

deactivate

[rich adder]

why do you need to deactivate it

[honest haven]

because the battle scene sits in the same pos as the old one so i see both at the same time

can i get back to you in 15 mins i just got to do a working meeting.

[rich adder]

if you want to be able to unload the scene without losing references to enemies, you could technically put all enemies in a DDOL so they can move whereveer without destroying

or put your battle scene in a different spot completly

old school pokemon for example doesn't use the same scene(probably) since the background/positioning changes

[languid spire]

'or put your battle scene in a different spot completly'
that would be the optimal solution

[deft glen]

does anyone know why this could be happening? its giving me absolutely no information

VS is giving me no errors either..

[rich adder]

how many errors are in console

its cutoff

[deft glen]

first 2 are when i try to do a build, last one is when i try to enter play mode

[rich adder]

restart unity, see if you get more errors or safe mode

[deft glen]

restarting seemed to fix it, probably should have tried that before posting here lmao

[rich adder]

good ol restart

[icy wedge]

hello guys, I'm having trouble activating a canvas from c#. If for example I toggle the small box next to the name, the canvas is visible on start and if i do canvas.SetActive(false); il will successfully disappear. But if I start with an inactive canvas, where i untoggled the box from start and do canvas.SetActive(true); it will not find it. I'm getting the canvas from canvas = GameObject.Find("UpgradeCanvas");. Any idea ?

The purpose of this is when I click on a box (which is a chest in the game), it should open a window that will be like an inventory or something like that

[rich adder]

Find does not work for inactive objects

also its a shitty method anyway

[icy wedge]

how do people do usually for that ?

[rich adder]

Just link it in the inspector

[icy wedge]

by adding a button component to my box ?

[rich adder]

[SerializeField] private Canvas canvas

drag n drop

if it isnt possible use a component FindObjectOfType<T>(true)

https://docs.unity3d.com/ScriptReference/Object.FindObjectOfType.html

[icy wedge]

i found a workaround because it did not work, i just keep it active and put it to inactive on start(), then whenever you click the object it somehow finds it

[iron mango]

i want to run a function every 1.5 seconds, what is the best way to do that? i thought of invokeRepeat, but this uses " ", does this mean it's searching for the function by name? is it better for performance to code a timer or just use that?

[rich adder]

Coroutine with while loop

  void StartRepeater()
    {
        StartCoroutine(RepeatTimer(1.5f));
    }
    IEnumerator RepeatTimer(float time)
    {
        while (true)
        {
            yield return new WaitForSeconds(time));
            //do something
        }
    }```

if you want to stop it store it in a coroutine object https://docs.unity3d.com/ScriptReference/Coroutine.html

[wintry quarry]

float timer = 0;
float interval = 1.5f;

void Update() {
  timer += Time.deltaTime;
  if (timer >= interval) {
    timer -= interval;
    MyFunction();
  }
}```

[iron mango]

i was asking because it's a strategy game and performance is very important ._. so yeah idk which one is best for that

[wintry quarry]

the Update one will be slightly better

it doesn't allocate garbage

The timer is also more accurate

though you can get an equally accurate timer and not allocate garbage in a coroute too - you just need to not use WaitForSeconds

[final kestrel]

private void HandleMovementInput()
{
  currentInput = new Vector2(walkspeed *Input.GetAxis("Vertical"),walkSpeed * Input.GetAxis("Horizontal"));
  float moveDirectionY = moveDirection.y;
  moveDirection = (transform.TransformDirection(Vector3.forward)*currentInput.x) + (transform.TransformDirection(Vector3.right) * currentInput.y);
  moveDirection.y = moveDirectionY;
}

I was watching a video on First person controls. Why do we store the moveDirectionY before calculating the moveDirection? and also set it back to where it was again at the end?

cos on moveDirection we already decide which way is forward and horizontal

[wintry quarry]

because they want to preserve the y part of it when they completely overwrite it with:

moveDirection = (transform.TransformDirection(Vector3.forward)*currentInput.x) + (transform.TransformDirection(Vector3.right) * currentInput.y);```

alsp transform.TransformDirection(Vector3.forward) can be simplified to transform.forward

likewise for transform.TransformDirection(Vector3.right) and transform.right

[final kestrel]

Why would you want to preserve?

is it for gravity and such?

[wintry quarry]

in fact I'd say this:

moveDirection = (transform.TransformDirection(Vector3.forward)*currentInput.x) + (transform.TransformDirection(Vector3.right) * currentInput.y);```
Would be better written as
```cs
moveDirection = transform.rotation * new Vector3(currentInput.x, 0, currentInput.y);```

[wintry quarry]

yes so the vertical movement remains natural

[final kestrel]

Ah okay so it has got nothing to do with restricting vector3 direction with vector2 input?

[icy wedge]

hey, let's say i have a Panel inside of a canvas, and I would like in c# start() to create a checkbox and place it inside of the panel ?

here is the code I'm using but it complains about NullReferenceException on the line GameObject checkboxGO = Instantiate(checkboxPrefab, panel.transform);

public class MixingTable : MonoBehaviour
{

    GameObject canvas;
    public GameObject checkboxPrefab;

    // Start is called before the first frame update
    void Start()
    {
        canvas = GameObject.Find("MixingTableCanvas");
        canvas.SetActive(false);

        GenerateCheckbox();
    }

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

    void OnMouseDown()
    {
        canvas.SetActive(!canvas.active);
    }


    void GenerateCheckbox()
    {
        GameObject panel = GameObject.Find("Panel");

        GameObject checkboxGO = Instantiate(checkboxPrefab, panel.transform);

        RectTransform rectTransform = checkboxGO.GetComponent<RectTransform>();
        rectTransform.localPosition = Vector3.zero;
        rectTransform.sizeDelta = new Vector2(30, 30);
        
    }
}

[rich adder]

so panel is null or checkboxPrefab is null

[icy wedge]

checkboxPrefab is probably null since it does not exist anywhere in the project, in fact i want to create the checkbox from here

[rich adder]

you didn't add anything in the inspector?

[icy wedge]

no

[rich adder]

so make the prefab lol

[icy wedge]

but it is just a toggle from ui, do i have to instanciate it in the hierarchy ?

the point is to create x amount of checkboxes like that

[rich adder]

if you want to create them via code yes make a prefab of a single checkbox and place it in field (from the project window not hierarchy)

ofc ideally youd have a container object with a custom script though so you can mess with that script directly

Hey yall I've been having some issue with this code for the past few days. I've managed to work out some minor errors but for some reaosn this one is really stumping me. I'm following a YT tutorial and just copying the code, and going through it real slow. My issue is that I keep getting "Unreachable Code detected" and "Not all code paths return a value"

I apologize if this is not the place, I'm just lost and have been struggling to find anything online that has been able to help me solve this on my own.

error 1 "for(int x = 0; x < WorldGenerator.ChunkSize.x; x++) - Unreachable code detected"
error 2 "ChunkMeshCreator.CreateMeshFromData(int[,,]) - not all Code paths return a value"

public  Mesh CreateMeshFromData(int[,,] Data)
    {
        List<Vector3> Vertices = new List<Vector3>();
        List<int> Indices = new List<int>();
        Mesh m = new Mesh();
        

        for(int x = 0; x < WorldGenerator.ChunkSize.x; x++)
        {
            for(int y = 0; y < WorldGenerator.ChunkSize.y; y++)
            {
                for(int z = 0; z < WorldGenerator.ChunkSize.z; z++)
                {

                    {
                        Vector3Int BlockToCheck = BlockPos + CheckDirections[i];

[deft grail]

you need to have a return in this code, and the error 1 is because the code is not possible for it to run so it gives an error that it cant

[rare basin]

is there a WaitUntil for coroutines but with unscaledDeltaTime?

cannot find anything :/

[wintry quarry]

You mean WaitforSecondsRealtime?

[rare basin]

No, I wan't a bool predicate

[icy wedge]

i made a prefab but im still confused how does the c# knows that I'm using TogglePrefab when all I say is public GameObject togglePrefab ?

[latent epoch]

I don't really get that cause I just copied the code word for word from the video I was watching and there was never a return statement. There is a try/catch statement that goes along with this, I just didnt want to post a wall of code lol

[rare basin]

yield return new WaitUntil(()=> hasLoaded)

[wintry quarry]

I don't see how scaled or unscaled time is relevant in that context

You can write whatever you want

[rich adder]

it doesn't , it just knows GameObject

[deft grail]

it doesnt know untill you set it in the inspector in Unity

[rich adder]

its up to you which component you want to grab

[rare basin]

because the courotine internal checks

works in Update
