I know for scriptable object, the editor doesn't like multiple classes

unless encapsulated

[summer stump]

I really don't know haha.
I thought the naming thing had to do with ECS where you may want a bunch of related components in one file (since they often only have one value per struct).

But that doesn't explain monobehaviours which I'm probably wrong about anyway

[teal viper]

Ecs components are not MonoBehaviour though, so they wouldn't need to change it for them to be stacked in one file.🤔

[summer stump]

No yeah, that's why I said I was probably wrong about it hahaha. That part is just about the file name matching the class/struct name

[teal viper]

Didn't read till the end...👍

[sullen rock]

can I somehow use convert an enum to an int easily? (basically use the 0-4 numbers without usign a switch or something similiar)?

[cosmic dagger]

just cast it to an int . . .

[sullen rock]

oh

well thats cool

thanks

[light moss]

My smooth camera follow makes my game lag a bit. How can I fix this issue?

[burnt vapor]

By providing more context around the issue, like relevant code

[burnt vapor]

(int)myInt / myInt as int casts it into the number it represents, assuming your enum inherits from an integer.
(string)myString / myString as string casts it into the string representation you defined the enum under.

If you plan on passing a number rather than an enum, I advice you use Enum.IsDefined or something similar before anything else.

[versed light]

so what exactly are am i suppose to use then

[stiff birch]

Delay the call ?

[versed light]

how do you do that in edit mode?

[stiff birch]

You may use this, not sure it will work but it is worth trying https://docs.unity3d.com/ScriptReference/EditorApplication-delayCall.html

[versed light]

thanks

[storm coyote]

anyway i can make a solid block that can only move when being pushed by certain tagged objects and acts as a solid walls for others using rigidbody?

[onyx tulip]

My Map moves slightly upwards and i don't know why

[solid coral]

If the animation of the parent is playing, then the animation of the child object is not played. I want to make the character stand up in a pose, and the weapon shoots, with its own animation. An animator has added an animator to the weapon, the trigger is triggered and the states are switched.

[tender stag]

can someone help me? this is on the Item script and its supposed to stack items, and it kind of works, but it removes both of the items since its on both scripts ```cs
private void OnCollisionEnter(Collision collision)
{
if(collision.gameObject.GetComponent<Item>())
{
Item collisionItem = collision.gameObject.GetComponent<Item>();

    if(collisionItem.itemData.maxStack > 1 && itemData == collisionItem.itemData)
    {
        Debug.Log("Items can stack");

        int totalAmount = amount + collisionItem.amount;

        if(totalAmount <= itemData.maxStack)
        {
            Debug.Log("Stacking items");

            amount = totalAmount;
            Destroy(collisionItem.gameObject);
        }
    }
}

}```

[timber tide]

lol wat

oh you're stacking with collision interesting idea

[tender stag]

how else would i do it

[neon ivy]

I'm making a pixel simulation and thus made a pixel data class, now I want to make this into a grid and my first thought was a 2d array but I'm wondering if anyone has any ideas that would work better?

[jovial mesa]

wouldn't it be simple to just instantiate a new GO "Stack" with the info of item amount in it ? Your items would both disappear and a stack would appear

[tender stag]

trueeeee

[jovial mesa]

the stack would be stackable as well but adding the correct number of items into the final stack

[timber tide]

Destroy doesnt happen till end of frame is the problem here

[jovial mesa]

(feel like I'm using "stack" a lot)

[timber tide]

Sounds fine to me

[neon ivy]

also how should I go about displaying this array?

[timber tide]

loops?

[neon ivy]

wondering if I want UI with horizontal and vertical layout groups or simply squares spaced apart

[timber tide]

wouldnt be too hard to make it in 3d space

[neon ivy]

wouldn't it cause rendering issues?

[timber tide]

Probably not more than doing it in 2D

just a bunch of quads

[neon ivy]

ok I'll try that, thanks :D

[tender stag]

got any other ideas?

[jovial mesa]

get Y position of items that collide, Destroy higher object and add stack information to lower one

[onyx tulip]

What can i do to change this?

[jovial mesa]

add collisions

[onyx tulip]

Not that i can go through walls

Look closely my map is moving upwards

[timber tide]

Could just make a member bool isStacking and tick it when one executes

there are no race conditions, so you'll have info when one or the other executes

it's just destroying doesn't work until end of frame, so even after being 'destroyed' it'll still run the logic

[tender stag]

https://hastebin.skyra.pw/imiyumojaf.csharp

something like this?

im so lost

[frozen dagger]

i dont understand whats wrong, it always make grounded tag true, and when i try to make it false in inspector it sets true, but i does not touch any object

[tender stag]

it works when like when i stack to the max stack size

[timber tide]

Ok, so the way I'm thinking of the logic is they collide, you check if the component you collided with is a similar item.
Now, if the component isn't being stacked, then you run the code and then flip isStacking to true. So, now the other item will run the same code and fail when it check's the other item isStacking

[frozen dagger]

...

[timber tide]

Your IDE* has a little green line there giving you a clue that might help

[frozen dagger]

if (grounded = true)
{
animator.SetBool("IsJumpingDown", false);
animator.SetBool("IsJumpingUp", false);
}

i removed it and it fixed

is it making tag true? how?

[timber tide]

when using the = operator, you're assigning something usually

but you're not trying to assigning anything here, rather you want to compare

which is the == operator

[frozen dagger]

okay, it helped, thanks

[timber tide]

always check the hints your ide gives you

[lean basin]

Hello, I'm trying to override Cinemachine input manually.
Documentation said:

Cinemachine has defined an interface: Cinemachine.AxisState.IInputAxisProvider. If a MonoBehaviour implementing this interface is added to a Virtual Camera or FreeLook, then it will be queried for input instead of the standard input system.

But how exactly am I supposed to do that?

I tried to make script and add it as a component:

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

public class CinemachineManualInput : AxisState.IInputAxisProvider
{
}

It's not correct... what is the correct way?

[modest dust]

An interface requires you to implement it's properties and methods

[lean basin]

ah right thank. It didn't hint me toward that earlier because I didn't add MonoBehavior before AxisState.IInputAxisProvider

[idle orbit]

A quick question, how should I code a side view camera movement where upon touching a certain position in the scene the camera will gradually advance forward, such as in an automatic scrolling level design or going through a doorway?

[unique hull]

I think theres a couple of ways to do that.
From the top of my head: Have a trigger depending on a specific number before it starts to move on its own , or you could use a collider for when it triggers / deactivates

So : Bool for when the camera follows the player and when its off - auto progress forward

[tribal locust]

Can U help me I have this error: NullReferenceException: Object reference not set to an instance of an object

check the value of any reference variables on those lines and make sure a value is assigned to it . . .

[tribal locust]

it is longer but I make it short

how are you gonna use the bot command then completely ignore it

[modest dust]

lol

[tribal locust]

oh ok Im stupid

https://paste.ofcode.org/Ngb34ML8W3ULbHvXTiEgLw

this?

[modest dust]

There's no Text component most likely on these GameObjects

You can also just reference the component instead in the inspector

not the GameObject

[slender nymph]

100% the issue is that they are using TMP_Text objects in the scene and not UI.Text objects

[north kiln]

You should not reference things via GameObject, it's a waste of time and leads to runtime errors like these

[tribal locust]

yea this is it the turtorial I copy it was older

[slender nymph]

yeah so take the advice the others gave and reference the components directly instead of referencing the GameObjects then using GetComponent. but also use the correct type

[tribal locust]

thanks all

[pine crown]

hello does anyone know how to fix this

[languid spire]

make TakeDamage public

[slender nymph]

when no access modifier is specified, it defaults to private

[pine crown]

o thanks dude

[delicate portal]

What does "{ get; set;}" in Unity mean?

[north kiln]

Same thing it means in C#

[languid spire]

not a Unity thing, it's a C# thing

[north kiln]

Should go through the scripting courses pinned to this channel if you do not know

[delicate portal]

Thanks

[north kiln]

It's the first topic in the immediate scripting course

[soft lotus]

Whats the diffirence between -= and =-

or more like, which does what exactly

[slender nymph]

one is the subtraction compound assignment operator. the other is the regular assignment operator with a negative sign after it

[brave compass]

=- means you forgot to add a space. It's valid, but i =- 1 is the same as i = -1

[north kiln]

-= (one operator) and = - (two)

[soft lotus]

Huh okay

[swift crag]

Spaces aren't mandatory

this also leads to funny things like 3 !>= 5

this returns false

it's actually parsed as 3! >= 5, where ! is the unary null-forgiving operator

(only relevant if you told the compiler to error any time you use a variable that might be null)

[faint osprey]

my animation wont play on my cinemachine i have it set to increase my fov in the animation and it plays through script and its not working

sounds like you're trying to use the (extremely) legacy Animation component

You should use an Animator.

[faint osprey]

why cant i use the legacy system

well, you can, but it's very old and barely used anymore

[cosmic dagger]

you'll have a hard time getting help on a deprecated design (component) . . .

I have a 2D game and for a certain reason I need the camera to be attached to the player as a child. Is it possible to have camera damping while the camera is a child of the player?

[swift crag]

Sure, but Cinemachine would make that really easy

just track the player and give the cinemachine camera some damping

[zealous oxide]

hey peeps, whats the best way to set a variable on a script on an instantiated object, from a separate, other script, thats instantiating said object. do I have to make a function for this in the instantiated object (lets call it "setProjectileDamage"), or is there an easier way?

[rich adder]

is damage() a method or a variable?

take out the () and it should work if damage is a public var
make sure prefab is of the type you're trying to interact with , eg your "other script"

[inland canopy]

Hello! Is it possible if i want to make movement for 2 different players in a single script

[rich adder]

yes

[zealous oxide]

its an INT variable in the script of the new instantiated object

[rich adder]

#💻┃code-beginner message

[cosmic dagger]

you can call a method with a parameter that assigns the variable you want to change, or if the variable is public, you can access it manually to assign its value . . .

[rich adder]

you could lets say use an enum to distinguish between player 1 / player 2 on the same script then set it to be different on each player

[snow mural]

How would I do if I want to generate and shuffle a deck the same for all connected clients, using netcode? I already have the working functions for generating deck and shuffling it.

[rich adder]

NetworkList

https://docs.unity3d.com/Packages/com.unity.netcode.gameobjects@1.2/api/Unity.Netcode.NetworkList-1.html

also #archived-networking

[snow mural]

sorry didn't see that channel, also thanks

[zealous oxide]

i've given this a go but its still throwing up an error message

[cosmic dagger]

display error message . . .

[rich adder]

what is the error?

[zealous oxide]

i dont mind using a function within the instantiated objects own script to set the variable (which is public!!) but i'm struggling to understand why I cant set it from the other instantiating script

[rich adder]

you have to change the prefab type to the script you want to access, like i mentioned here #💻┃code-beginner message

it cannot be GameObject

[swift crag]

GameObject does not have a member named damage. It never will.

the type returned by Instantiate is the type you gave it. if your prefab variable is a GameObject, then you'll get a GameObject back

it'll be a game object with your projectile component on it, sure

[cosmic dagger]

the instantiated object returned is a GameObject type. you need to access the component on the GameObject . . .

[zealous oxide]

im trying to work my head around how do i make this work

[cosmic dagger]

change the type of the prefab to instantiate the type you want to access . . .

[rich adder]

^^

    public GameObject prefab; //old
    public MyScript prefab;//new

[swift crag]

you can reference a prefab as a GameObject, or as any component on the prefab

Instantiating a component instantiates the entire object the component is attached to.

Prefabs references should almost never be a GameObject.

You want something more specific than literally any game object, right?

[cosmic dagger]

A GameObject is a container holding a list of components; its prime use is activation and deactivation. Primarily, we need a specific component attached to the GameObject. Change the type of the variable (field) to the component (you want to access) instead; this avoids using GetComponent whenever we grab an item from the object pool . . .

[zealous oxide]

this is a lot and i'm lost now

it sounds like using a method on the new objects script would be easier?

[cosmic dagger]

show the code where you declared your prefab (the one you instantiate) . . .

[cosmic dagger]

either option: calling a method, or assign the variable manually is only a single line . . .

[zealous oxide]

https://hastebin.com/share/koqokuyehe.csharp heres the whole script

[cosmic dagger]

your prefab variable is a GameObject. a GameObject does not have the damage variable you're trying to access. does that make sense?

[zealous oxide]

yeah, i can understand that

[cosmic dagger]

what script has that variable?

[zealous oxide]

this, which is attached to the prefab being instantiated

[cosmic dagger]

then you need to use that script as the Type of the prefab variable instead of GameObject . . .

[polar acorn]

So you should have a variable of type CrescentDartProjectile and drag in your prefab

[cosmic dagger]

now, when you call Instantiate it will create a copy of the GameObject, but return a reference to the CrescentDartProjectile script, allowing you to access its public members . . .

[zealous oxide]

so change the "GameObject" into "Type" ?

[swift crag]

No.

[swift crag]

.

[swift crag]

^

that's all

[cosmic dagger]

no, Type in this context is the class you want access to, your CrescentDartProjectile . . .

[polar acorn]

I don't know what this has to do with anything we're saying

[summer stump]

They mean in the code

[swift crag]

you are showing us random screenshots instead of doing this..

[zealous oxide]

ok so i've gotten rid of the line that said public GameObject prefab and replaced it with " public CrescentDartProjectile prefab;//new
"

if i'm understanding this right, this should now work as intended?

wow, that worked, thank you all for your help.

[faint osprey]

right so my player is riding a cart and when they jump off it i want the momentum from the cart to be conserved onto the player how would i do this

[wintry quarry]

if the player is riding on the cart don't they already have that momentum?
Baically it's going to boil down to how your player movement works generally and how the "riding the cart" mechanic works

[polar acorn]

How is the player "riding" the cart?

[faint osprey]

its attached to the seat and the cart gets translated

[wintry quarry]

the short answer is "when the player leaves the cart, give it the same velocity the cart had"

[faint osprey]

the cart doesnt have a rigid body tho

[polar acorn]

So there is no momentum or velocity involved. If you want physics-like movement, you should probably use physics

[wintry quarry]

but you know the velocity, because you're moving it.

[faint osprey]

im translating it tho

[wintry quarry]

so?

You're translating it by the amount equal to the velocity you want to impart to the player

[stiff stump]

how can i get all the colliders that overlap another collider?

[wintry quarry]

2D? 3D?

[stiff stump]

2d

[wintry quarry]

https://docs.unity3d.com/ScriptReference/Collider2D.OverlapCollider.html

[faint osprey]

thats true well i could modify the movement speed when it jumps off the cart then change it as they hit the floor but if they jump off and dont press any buttons they wouldnt move at all tho

[still wren]

does this code give random values between 1 and zero into a 2d array

[stiff birch]

Didn't you write it ?

[still wren]

i dont know if i did it correctly

[stiff birch]

Then test it and see if you get satisfying results

[still wren]

what does the perlin noise look like in unity

i mean to say that if it is like the one on the left or right?

[polar acorn]

Yes.

(The joke being that these are both perlin noises with different parameters)

[stiff birch]

It's just a question of scale here i think

As digiholic say, you can obtain both result IIRC

[radiant vector]

I'm struggling with my bullets. They work fine if I am going straight ahead but since my ship continues on it's velocity when turned if I shoot the bullets don't take the ships velocity. I was thinking of using Vector2.Dot(xx,xx) but I'm not sure what the solution is. I want them to adopt the moving direction velocity. :/

Relevant Code: https://gdl.space/bicilesevi.cs

[radiant vector]

Here's a good tutorial: https://youtu.be/bG0uEXV6aHQ?si=CGDr-CJ30-Ayak8E&t=542

I linked to the relevant part where you change the scale and the image looks like the left or the right in your examples.

[swift crag]

It will depend entirely on the scale you sample the noise at

[still wren]

how do i scale the noise

@swift crag

[swift crag]

Mathf.PerlinNoise(x, y) samples the noise at coordinates [x,y]

suppose you plug in positions in your world

you'll sample 0,0 at the origin, 1,0 one meter to the right, etc.

now, instead of plugging in the position, plug in the position divded by 10

now you're sampling 0 , 0 at the origin and 0.1 , 0 at one meter to the right

[still wren]

oh

[swift crag]

This stretches the noise out by a factor of 10.

[rich adder]

not an expert but..such a weird way to move
Vector3 pos = transform.position; Vector2 velocity = new Vector2(0, (bulletSpeed + playerSpeed.magnitude) * Time.deltaTime); pos += transform.rotation * velocity; transform.position = pos;

[faint osprey]

is it possible to test for a collision between two objects when neither of them have a rigid body

[still wren]

a seed is put in (like minecraft) and the actual number is generated from GetHashCode()

[rich adder]

no, collisions is physics

[still wren]

then i just use a random and get a random number from that seed

then we plug that in when getting values

[swift crag]

If you make the numbers that go into PerlinNoise larger, then the noise will change more rapidly

If you make them smaller, then the noise will change more slowly

[still wren]

it changes by 1

[radiant vector]

Should I scrap it and rethink the approach?

[rich adder]

You can use physics casting if you don't want to use rigidbody to check for colliders

[queen adder]

Just set the initial velocity of the bullet to be equal to the ship velocity

[still wren]

if the seed is 10, then it starts at (10, 10) then goes to (10, 11) then goes to (10, 12)

[swift crag]

note that adding an enormous random number doesn't really make sense

did you mean to add a random value between 0 and 1?

System.Random.Next is a random integer

[rich adder]

yeah why would the bullet not just be
rb.velocity = transform.right * speed; (assuming your object default points Red arrow)
or w/e

[still wren]

thats to make it different everytime

[queen adder]

Also why are you recalculating the velocity every frame? @radiant vector

[radiant vector]

good point. Calculate one time, then move it the same amount every frame.

[swift crag]

oh, I see, it's constant

gotcha

I would still use smaller numbers. You're going to run into problems with floating point precision with huge numbers.

[radiant vector]

Let me try something like this. I know I tried it but I forget why it didn't work.

[swift crag]

Maybe just add a random value between 0 and 10000 or something

anyway, multiply x and y by a scale factor to change how big the noise is

[faint osprey]

so id shoot a raycast to test instead?

[still wren]

yeah if the mapwidth and mapheight are 10, then it takes 100 values from a random point on this infinite perlin noise

but its for the purpose of, if u want to always have the same world, then u can always enter the same seed

[swift crag]

also, that reminds me

[rich adder]

then assign the direction

as long as you spawn the bullet with the ships rotation

var bulletInstance = Instantiate(bulletPrefab, firepoint.position, ship.transform.rotation) etc..

[swift crag]

I believe perlin noise is 0 at integral coordinates

[still wren]

what does integral coordinates mean

[swift crag]

coordinates where every number is an integer

[3,0]

hm, it's not zero, but it's certainly the same value every time

I tried Debug.Log(Mathf.PerlinNoise(Time.frameCount, 0))

It's always 0.4652731

[still wren]

so i have to use floats

[swift crag]

So, you should definitely be rescaling these coordinates

[still wren]

or multiply it by something

[swift crag]

I would suggest doing this

float sampleX = x * scaleFactor;
float sampleY = y * scaleFactor;
Mathf.PerlinNoise(sampleX, sampleY);

where scaleFactor is a float

[still wren]

ok

scalefactor should be a const float though

[swift crag]

well, it probably won't be changing

[still wren]

wait why dont i just add 0.5f to it?

[swift crag]

but making it const will stop you from editing it in the inspector

[swift crag]

that helps, but you might as well add scaling here too

[still wren]

this is on a static non monobehaviour script anyways

[spare relic]

i have a very rudimentary question
if i want to fade in/fade out a canvas
is it better to use an animation system or modify the alpha/opacity value of an image directly from code

[swift crag]

I just do it in code.

Animation makes sense when you can't easily express the animation in code.

for example, animating a character's limbs

[spare relic]

yeah thats what i was wondering

[swift crag]

I do this all the time

[spare relic]

cause it can easily be done in code

alright ty

[swift crag]

canvasGroup.alpha = Mathf.MoveTowards(canvasGroup.alpha, shown ? 1 : 0, Time.deltaTime);

shown is a bool
canvasGroup is a CanvasGroup

[spare relic]

thank you im going to try it out now

[edgy prism]

Hello I created this function however after adding the foreach statement it tells me not all code paths return a value

public string UpdateObjectiveProgress()
    {
        foreach (var quest in questList.Quests)
        {
            if (quest.Base.RequiredItem != null)
            {
                var inventory = Inventory.GetInventory();
                int itemCount = inventory.GetItemCount(quest.Base.RequiredItem);

                return $"Obtain {quest.Base.RequiredItem} ({itemCount}/{quest.Base.RequiredCount})";
            }
            else
                return quest.Base.ObjectiveText;
        }
    }

[polar acorn]

What should it return if questList.Quests is empty

[earnest forge]

Hello, I'm looking for a way to create grid lines similar to Debug.DrawLine? Any suggestions? currently looking at either using LineRenderer (which will require handling many line renderers) or instantiating gameobjects per grid box

[edgy prism]

Nothing

[polar acorn]

So, you'll need to tell it that

[edgy prism]

I tried just else return but thats not correct

[polar acorn]

Put a return statement after the foreach loop

[edgy prism]

Im unsure how best to do that because if I return an empty string that im not going to set to anything wont I get a null reference error?

[swift crag]

you MUST return a string

an empty string is a valid string

a null reference is also, according to the type system, a valid option

probably not what you want

[polar acorn]

Strings can't be null. Your function will return a string in every case, or it won't compile. That's why you have to tell it what string you want to return if the list is empty

[edgy prism]

It wasn't the string itself I was worried about it was where I use it but I realised im being stupid and can just check where I call the function if questList.quests.Count > 0

[polar acorn]

||Update: upon further review, strings can be null in C#. Still probably shouldn't return null though||

[swift crag]

strings are just immutable; they aren't value types

[edgy prism]

What do you mean by immutable?

[swift crag]

You can't modify a string in-place

so with an array, you can do

arr[3] = 123;

you can't do that to a string

obviously you can reassign the variable entirely

[edgy prism]

If I return null would that anger you?

[swift crag]

but that's not modifying the contents of the variable

[polar acorn]

It might anger the compiler

[swift crag]

well, if you try to display that string, you'll have a bad time

an empty string sounds fine, as does "No active quest"

[edgy prism]

Yeah I see the issue but the case for this string is the string thats never going to be used

So im assuming I can just return an empty string and not worry about it?

[swift crag]

Sure.

If this is an unusal situation that should never happen, you could throw a Debug.LogWarning in there

I do that in places that shouldn't ever be reached

[edgy prism]

Ok good Idea I will do that then!

Thankyou both

[weary crystal]

Um help, a = b, why are the saying first number is equal to second, I don't understand...?

[polar acorn]

== means "Are these equal?"

a == b is asking a question. It returns true if a equals b.

If they are not the same, it will return false

[swift crag]

= is the assignment operator; == is the equality operator

[wintry quarry]

== is in the same family as > < >= <=. It's indeed comparing two things and giving back a result

[swift crag]

if only we used <- for assignment

):

[weary crystal]

Ohh, wait, I got it.

Thanks!

I still kind of don't understand though, I mean "a" is not equal to "b"

[weary crystal]

but also they are not greater than 10

so if they are greater than 10 but not same, it'll return false.

[polar acorn]

That does appear to be what this lesson is trying to convey

&& means "and"

[weary crystal]

but if the answer is greater than 10 and it is not same, it will also return false?

[weary crystal]

Yeah I know about this, thanks.

[polar acorn]

if their sum is greater than 10 and the first two are equal, do the first block. In literally any other case, do the second

[weary crystal]

Ohh, yeah damn, I got it, thank you so much and sorry.

uh why my browser crashed??

[swift crag]

while (counter < 10);

This is a while loop that runs an empty statement

[faint osprey]

hey is there anyway to make ur raycasts visible to check stuff

[swift crag]

; ends a statement. A while loop applies to the next statement.

So you're doing nothing as long as counter < 10 is true

[summer stump]

Debug has something
Debug.Ray?

[swift crag]

Notice the squiggle here. The compiler is warning you about this

[faint osprey]

ill try that thanks

[summer stump]

Debug.DrawRay
Just looked it up
https://docs.unity3d.com/ScriptReference/Debug.DrawRay.html

[weary crystal]

Oh, so it kept like repeating the loop that made my browser crash?

[faint osprey]

thank u

[swift crag]

your browser freezes until it's done running, so yeah

[weary crystal]

Got it, thanks.

[faint osprey]

            {
                Debug.Log("woking");
                sitCheck();
                pm.isSeated = false;
            }```

my ray cast isnt working

and im not sure why

[swift crag]

Try using Debug.DrawRay to visualize the raycast

so, Debug.DrawRay(gameObject.transform.position, cylinder.transform.up, Color.green, 1f);

that'll draw a green line that lasts for 1 second

[wintry quarry]

just a little tip - the == true part is never needed and is just extra noise

if is already checking for true

anyway "doesn't work" doesn't mean too much to us. Perhaps if you explained what you are expecting this to do and what it's doing instead?

[faint osprey]

i have no idea what its doing cause when i draw the raycast out in debug i cant see it at all and i want it shooting out from the front of a gameobject and if it hits a game object marked with layer "ground" for it to be true

[onyx prairie]

why can't i put my CharacterController component into the Character Controller reference?

[spare relic]

i customized it a little bit it works nicely ty

[polar acorn]

Does your script name match your class name

[short hazel]

Your own script is called CharacterController, so you can only drag-drop yourself on it. Change the script name

[onyx prairie]

ty!

[polar acorn]

But also do make sure they match

[swift crag]

Oh that's funny -- the original CC icon still shows up

[short hazel]

Yeah last compilation pass failed, that's why

[onyx prairie]

already did it, they didn't match

fixed it

[summer stump]

Where are you casting the ray? It's in update, right? The ray only lasts a frame, so you have to keep calling it

[swift crag]

If you can't see the ray, then you're either shooting it from the completely wrong place, or you're not shooting it at all

[wary delta]

Post the whole script via pastebin.com or similiar

[ionic totem]

Hey guys, just a quick q (might be an easy fix but new to unity thx) my models clothes n hair etc is glitching through any idea how to fix?

[rich adder]

probably not a code question

[ionic totem]

oh yea sorry!

[faint osprey]

im setting a bool fron another script true in a different script and im getting the object refrence not set to an instance of an object error does anyone know a fix

[weary crystal]

Why everything I have learned feels like I understood nothing bruh

[languid spire]

you are not getting a good reference to the other script. Do you check?

[polar acorn]

Reference an object instead of not doing that

[cosmic dagger]

make sure the reference object is not null before attempting to access it . . .

[faint osprey]

well its set to false before so i dont know why it would be null

[faint osprey]

wdym

[languid spire]

the bool is not a null, the reference to the object holding it is

[summer stump]

You should probably just share the code at this point

[polar acorn]

Your error says you're trying to get something from a reference that doesn't exist. Instead of doing that, try using an object that exists instead.

[wary delta]

Post your code via pastebin

[cosmic dagger]

the object reference can be destroyed before you access it again to change the bool variable on it . . .

[faint osprey]

            {
                Debug.Log("woking");
                pad.GetComponent<BoxCollider>().enabled = false;
                StartCoroutine("colliderCooldown");
                sitCheckFalse();
                playerm.isSeated = false;
            }``` its the last bool statement which is the issue

[faint osprey]

its not being destroyed

[polar acorn]

playerm is null

[faint osprey]

how

[summer stump]

How do you reference playerm?

[polar acorn]

¯_(ツ)_/¯

You haven't showed us anything related to how you're getting the reference

[summer stump]

We can't know with only that snippet

[faint osprey]

PlayerMovement playerm;

[summer stump]

You should share the whole script with a paste site

[cosmic dagger]

is this variable assigned from the inspector or through code?

[summer stump]

That is a declaration. It doesn't mean it's referenced

[faint osprey]

oh it needs to be public

right

[cosmic dagger]

that is a declaration. there is no assignment here . . .

[summer stump]

Well, not ONLY. You also have to reference it

You could also do it other ways, but public allows you to do it in the inspector (also another way, but I won't add more confusion)

[cosmic dagger]

quick question: how do you assign the number 5 to an int variable?

[wary delta]

Paste the whole script via pastebin

[faint osprey]

(variable name) = 5;

[cosmic dagger]

right. did you do the same thing with the playerm variable? did you assign it to a value?

[faint osprey]

its not a variable its a class

[wary delta]

Ffs

[summer stump]

That you have as a variable. The class is the TYPE of that variable

Collider is also a class. But you use those as variables, right?

[cosmic dagger]

PlayerMovement playerm;
int health;

no, playerm is a variable of the type PlayerMovement, just like health is a variable of the type int . . .

[polar acorn]

Okay so where do you set it

[faint osprey]

its fixed now u guys gotta chill lol

[cosmic dagger]

a class is a Type, moreso, a reference type . . .

[summer stump]

Everyone is "chill". We're trying to help you...
But sure, insult us lol

[wary delta]

Like 5 people asked you to post the script

[cosmic dagger]

chill, we're just trying to help? 🤔

[polar acorn]

I'm not chill but that's just sort of a state of being for me, I'm always highly caffeinated and anxious

Unrelated to the current situation

[green copper]

I'm using the Modular First Person Controller from the asset store to control a bumper for a pool game type thing, to allow the player to steer around a bumper. I glued a cube to the player and applied a super bouncy physics material, but whenever the ball impacts the bumper it loses all velocity. The physics material is working on the walls of the play space, all velocity is correctly retained.

[swift crag]

Does the ball bounce correctly when it hits something else?

that's what I'd look at first

[green copper]

yes, the walls of the play space are made of a cube with the same physics material and it behaves as expected

[swift crag]

a pool game type thing

is the ball hitting the bumper, or is the bumper flying into the ball?

[green copper]

all velocity towards the player is lost, but any sideways skew is retained

the ball essentially stops dead and begins drifting to whichever side it already had sideways velocity in

[green copper]

either one, whether the player is actively ramming the ball or the ball is flying into a stationary player

the properties of the two bodies, if relevant

and the scene heirarchy

the chaos balls are set to be given a 50 velocity kick on game start and have their y level locked to 2 with no gravity, so they skim the ground without drag or gravity and bounce infinitely

[eager maple]

Is there some way to fix A polygon of Mesh ..... in Assets/Prefabs/Office.fbx is self-intersecting and has been discarded.
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

[swift crag]

your model has a weird polygon in it

[eager maple]

how would I fix it

[swift crag]

like a quad shaped like this

you could go look at the model in Blender and try to find the bad polygon

or just ignore it

[eager maple]

hmm, how should I like, make it work

[swift crag]

is something not working right now?

that's just an import warning

[eager maple]

the fbx looks horrible

[swift crag]

that's very vague.

[eager maple]

missing a lot of textures and all

[swift crag]

(this is also not a code problem)

[eager maple]

half of the textures

[eager maple]

oh yeah

[swift crag]

you can ask in #🔀┃art-asset-workflow . I'm guessing you need to go manually assign some textures.

[green copper]

Just did a test and can confirm the behavior also functions when two balls collide

[wary delta]

Check if the rigidbody is sleeping after it contacts the bad box

[green copper]

how can I check that? pause and framy-by-frame or do I need a script?

[wary delta]

In the script, debug log therb.isSleeping()

[green copper]

should i put that in update or oncollision?

[wary delta]

On collision

[green copper]

enter or exit?

[wary delta]

Both technically, but I'f it's sticking it might not be exiting

[green copper]

returning false on both wall and player collisions

[idle karma]

I'm quite stupid and can't figure this out

[short hazel]

[swift crag]

yes, your code editor should be flagging the error for you

[idle karma]

ah yeah fuck I capitalized the b

ty

[green copper]

both functions are returning true, as well. Checked, both Enter and Exit are running

[wary delta]

Damn. I got nothing then. Whats the box that's not working look like. Is it intersecting another collider?

[green copper]

there's a capsule on the back that's part of the player controller, could that be causing it?

[wary delta]

Move the box a little bit further away.

[tender stag]

hey there, this is my item script, and the OnCollisionEnter destroys both items when stacking them together
https://hastebin.skyra.pw/kucufawatu.csharp

[wary delta]

And off the floor a lil

[tender stag]

its because the script is on both items

thats why it destroys them both

but i dont know a way around it

[ashen ferry]

I guess they both destroy themselves cause they both run that method lol

[tender stag]

yeah

i know

but how do i go around that?

[wary delta]

When is sleep true?

[green copper]

typo, sleep is always false

[wary delta]

Oh ok

[ashen ferry]

make one of them special somehow maybe lifetime in the world whoever is newer it gets destroyed for older one

[green copper]

Adjusted positions, no effect

[wary delta]

Might need to move to physics channel

[green copper]

ok

[idle karma]

Does it matter which one I press

[rich adder]

yes

[slender nymph]

select the one you actually plan to use

[rich adder]

and make sure its the one that has Unity Workload installed :p

[idle karma]

idk the difference

Both have unity workload installed

I also have this if it matters

Idk which one to use either

shit's confusing

[slender nymph]

well one is a preview version. surely you didn't just randomly install that for no reason and actually planned to use it for something? or did you just go and install each free version?

[short hazel]

I'd use the third one since it's the stable release. Second one has nothing to do with Unity, and as the description says, it installs the tools required to make software without VS installed

[rich adder]

yup old way of getting VScode to work with unity back in the day was using the Build Tools

[queen adder]

any way i can get the geometry of, say, this tree with Physics.OverlapSphere? it doesn't have a collider

[rich adder]

you need collider

[slender nymph]

it doesn't have a collider
then it will not be detected using a physics query like Physics.OverlapSphere

[idle karma]

I have no idea honestly it was a long time ago

[wintry quarry]

what do you mean by "get the geometry" exactly? The Mesh it's using for its MeshFilter/Renderer defines its geometry.

[idle karma]

So I should use the Visual Studio Community 2022 one?

[rich adder]

yes

[short hazel]

Yes

[queen adder]

yeah, I'd like to be able to check if there is a mesh at a specific position for an effect

[wintry quarry]

give it a collider

it doesn't need to be perfect. Looks like a CapsuleCollider will be a decent approximation in this case

[queen adder]

and i oop

it just needed a mesh collider haha

[ashen ferry]

ayo ur making that horror game?

[idle karma]

Can I uninstall the other two?

[rich adder]

yes

[queen adder]

im making that horror game

[ashen ferry]

ill live to see it being made on like 20 platforms

[slender nymph]

if you don't need collisions for it that match perfectly to its mesh, just use a primitive collider like a capsule or box collider.

[queen adder]

(what horror game are we referring to)

[ashen ferry]

idk I forgor

[queen adder]

i forgor 💀

[ashen ferry]

your map is dark and u shoot lines they hit walls and entities

thats how u navigate

[queen adder]

oh i rember 😄

lidar.exe or whatever

[ashen ferry]

yeaa

[queen adder]

this is not lidar game dw :)

[rich adder]

sounds cool

like a spin off of Outlast but with newer zoomies technology

[queen adder]

Basically it's a sound-based horror game where your footsteps reveal the environment :)

[rich adder]

DareDevil - the game

[queen adder]

now i just gotta figure out how to apply a mesh collider to this model i imported.

[wintry quarry]

Add Component > MeshCollider

[weary crystal]

???

It works if I use " instead of '

but why?

[rich adder]

because ' ' is for char

" " for strings

[weary crystal]

oh so ' is for one character and " is for words, right?

[rich adder]

pretty much

[weary crystal]

Ohh, alright.

Thanks

[cosmic dagger]

for strings, not necessarily words, but a string of chars . . .

[weary crystal]

Got it.

[junior ether]

if I use the input action on the keyboard "any key" can I print out what key am I pressing?

[wintry quarry]

Are you talking about this? https://docs.unity3d.com/ScriptReference/Input-anyKey.html

[junior ether]

no

im talking about the new input system

with callback context

can i print out from the callback context which key im pressing?

[rich adder]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.6/api/UnityEngine.InputSystem.InputSystem.html#UnityEngine_InputSystem_InputSystem_onAnyButtonPress

I think

[weary crystal]

Uh what am I wrong doing now?

[wintry quarry]

you are missing some operators?

You just have d e with nothing between?

and a * b <what goes here??> (c + ..

[weary crystal]

Oh bruh, got it, thanks.

[slender nymph]

yeah unlike when writing the text as a math expression on paper or something where the multiplication operator can be implied, in programming the operators are required

[tender stag]

can someone help me make the OnCollisionEnter so that it doesnt destroy both items?
https://hastebin.skyra.pw/usefizalih.csharp

[polar acorn]

Is this script on both objects

[tender stag]

yeah on all items

[wintry quarry]

    private void OnCollisionEnter(Collision collision) 
    {
        if (gameObject.GetInstanceID() < collision.gameObject.GetInstanceID()) return;
        // the rest.

[tender stag]

what does that do?

[polar acorn]

Clever

[wintry quarry]

it makes sure one of the objects runs the code and the other doesn't

[polar acorn]

The instance ID is effectively a random number assigned to each object. One of them will be less than the other, and that one gets to live

[tender stag]

like this?

or have i got the wrong idea

[wintry quarry]

no

copy my code

you messed up the first part and now it makes no sense

[weary crystal]

!cdisc

[eternal falcon]

Join the C# Discord server, a programming server aimed at coders discussing everything related to C# (CSharp) and .NET. https://discord.com/invite/csharp

[tender stag]

it works

but

sometimes when i drop like you can see it gets stacked to the item on the floor, but sometimes the floor item gets stacked to the item which still has velocity

how could i make it so that it always gets stacked to the item on the floor?

[wintry quarry]

if you have some particular criteria you want to use to determine which item is destroyed and which isn't, go ahead and use that. The one I provided is merely guaranteed to pick one of them, but makes no promises about which

If you want to do "destroy the one at a higher y position", that should be simple enough to do
basically the same technique as the code I shared, just checking a slightly different thing.

[ashen ferry]

imo implement lifetime like I said im assuming you will want to despawn very old items later on as well it will double as factor which item runs its code

[tender stag]

maybe the one which has less velocity?

[tender stag]

when im splitting items in my inventory i instantiate new ones

[wintry quarry]

if you can dream it, you can write the code for it

[tender stag]

so that wouldnt work

[tender stag]

thats why when i split the item, and then throw it out it gets stacked to the floor item

and when i throw the original item without splitting the one on the floot gets stacked to the one you threw out

[ashen ferry]

no like imagine your on ground item has lifetime of 40 seconds since it got dropped and your new dropped item has only half of a second since it just started existing in world then you can compare and stack to the older one, solving your current problem + use that lifetime to despawn old items to not clutter

what u do in ui dont matter its only ui representation of ur item not like an entity in the world

[tender stag]

yeah but when i split items in the inventory

into half

i instantiate a new item

wouldnt that matter?

[ashen ferry]

is ui item class same as the item you drop into the world?

[tender stag]

look at the hierarchy

[ashen ferry]

why u do that

[tender stag]

wdym

[ashen ferry]

u dont need items to exist in world to have them in inventory

[tender stag]

yeah ik, but when you drop them they wont appear from air

so i do need them to exist

because when i drop an item out of inventory

all i got to do left is set it active

and add force

[ashen ferry]

visually they still appear from air

[polar acorn]

Your inventory slots should probably always exist and you just change what sprite and number they display based on what item is in that slot

[ashen ferry]

anyways u need to change ur whole inventory setup for my thing to work so forget it

[tender stag]

thats what i do

yeah to check which one has less momentum is the best option

probably

yeah im lost, it doesnt work```cs
private void OnCollisionEnter(Collision collision)
{
if(collision.gameObject.GetComponent<Item>())
{
Item collisionItem = collision.gameObject.GetComponent<Item>();

    if(collisionItem.itemData.maxStack > 1 && itemData == collisionItem.itemData)
    {
        float thisMomentum = GetComponent<Rigidbody>().mass * GetComponent<Rigidbody>().velocity.magnitude;
        float collisionMomentum = collisionItem.GetComponent<Rigidbody>().mass * collisionItem.GetComponent<Rigidbody>().velocity.magnitude;

        int totalAmount = amount + collisionItem.amount;

        if(totalAmount <= itemData.maxStack)
        {
            if(thisMomentum > collisionMomentum)
            {
                collisionItem.amount = totalAmount;
                collisionItem.GetComponent<Rigidbody>().mass += GetComponent<Rigidbody>().mass;
                Destroy(gameObject);
            }
            else
            {
                amount = totalAmount;
                GetComponent<Rigidbody>().mass += collisionItem.GetComponent<Rigidbody>().mass;
                Destroy(collisionItem.gameObject);
            }
        }
    }
}

}```

[wintry quarry]

you should be doing something like my previous code was doing

check if you are the faster or slower object

if you're the faster object, jsut return

the other object will run its code and destroy you

[tender stag]

yeah i tried and its giving me errors

when the item touches ground

[ashen ferry]

https://hatebin.com/qgqgofanes try this

[tender stag]

or anything

[wintry quarry]

you naturally need to check if the object HAS a rigidbody before using the Rigidbody

TryGetComponent would be useful

also avoid using GetComponent so much - cache the reference

you can also probably just throw that in as the first line inside the if (collision.gameObject.GetComponent<Item>()) block

and it should be fine too

[unreal imp]

guys, why is my instantiate not working? I made this condition and even if I set it as true by default, the particle is not generated void Update { if (isInFire) { Instantiate(fireParticles, transform.position, Quaternion.identity, transform); var v = fireParticles.GetComponent<DestroyInRandomTime>(); if (!v.isActiveAndEnabled) { hitsReceived = maximalHitsToDestroy; } } }

[wintry quarry]

isInFire is likely false

You can verify with Debug.Log

[short hazel]

And if it's true, you're getting stuff on the prefab

Not the instance you created in the scene

[wintry quarry]

if you just did

public bool isInFire = true;``` that's not going to affect any already serialized components in the scene.

You need to actually set it in the inspector

[unreal imp]

even if i set the bool in true it happen anyway

oh,thanks

[wintry quarry]

show how you did so

because you probably didn't do it properly

[acoustic arch]

https://hatebin.com/dadnyhdzry

[short hazel]

var clone = Instantiate(prefab, ...);
var p = clone.GetComponent<T>();
// use 'clone' and 'p'

[acoustic arch]

how come the rotate on the camera returns back to its original after the turn of the mouse variable changes at all? (lines 9-10 and 25-27)

[acoustic arch]

^

[unreal imp]

            }
        }
    }
}

[short hazel]

Somehow Start is marked as obsolete lol

[wintry quarry]

right so like I said public bool isInFire = false; if you just changed this to true that's not enough, you need to set it in the inspector

[tender stag]

in theory this should work now```cs
private void OnCollisionEnter(Collision collision)
{
//If the collision is even an item
if(collision.gameObject.GetComponent<Item>())
{
//If you are the slower item
if(gameObject.GetComponent<Rigidbody>().velocity.magnitude < collision.gameObject.GetComponent<Rigidbody>().velocity.magnitude)
{
Item collisionItem = collision.gameObject.GetComponent<Item>();

        //If this item is even stackable and is the same as this item
        if(itemData.maxStack > 1 && itemData == collisionItem.itemData)
        {
            int totalAmount = amount + collisionItem.amount;

            //If the total amount of both items can fit into the max stack size
            if(totalAmount <= itemData.maxStack)
            {
                amount = totalAmount;
                Destroy(collisionItem.gameObject);
            }
        }
    }
}

}```

right?

[ashen ferry]

we use Begin(); now

[unreal imp]

oh ok i will try

[short hazel]

void Begin() {
  pinMode(1, OUTPUT);
}

[unreal imp]

because if i not put that,the random var returns me a warning

[short hazel]

Yeah you should be using Random.Range()

It's RandomRange() that's obsolete, the warning should be telling you that

[wintry quarry]

Oh my god that's adorable

[languid spire]

Unbelievable

[unreal imp]

😊

😘

[languid spire]

Let me guess, the namespace System and the namespace UnityEngine both have a class called Random

[tender stag]

does awake get called when an object is instantiated?

[summer stump]

Yes

[wintry quarry]

it gets called during the Instantiate call in fact. By the time Instantiate returns, Awake and OnEnable will have already run on the newly created object (assuming it starts out enabled)

[unreal imp]

also anyone knows how to simulate the fire in barrels like gmod?

[polar acorn]

Particles, probably

[unreal imp]

the fire is semi transparent,and it is in a position in the middle of the object which if the rotation of the object changes the rotation of the fire will not be affected either

[wintry quarry]

Yep particles

[short hazel]

Just make sure the particles are simulated in world space (setting to change) and you'll be fine

[unreal imp]

oka

wait, to make the particle not rotate relative to its parent object, do you use Quaternion.Identity?

[wintry quarry]

no

you simulate it in world space

which was the whole point of mentioning that

[unreal imp]

Mmmm that thing is familiar to me

[tender stag]

it works now

[unreal imp]

Thanks for your patience

[spare relic]

i would recommend against calling get component in any method that gets called beyond Start unless it only runs once

[tender stag]

it runs once

[summer stump]

Drop only runs once ever?
It should run every time you drop an item, right? In that case it may be better for item to simply have a reference to its own rigidbody.

[tender stag]

i thought he meant like in update

yeah it runs every time you drop an item

[ashen ferry]

what is going on why my draggable rect transform isnt at 1:1 sensitivity https://hatebin.com/viqsujtofv you can see mouse moving centimeter on screen but star image which is child of "StarsRoot"(the thing which is dragged) moves like 3 apparently scale can mess it up but my whole hierarchy is at scale 1 so what else

[wary delta]

That's a double transform

[ashen ferry]

why double?

[wary delta]

I've never experienced it in unity. I've only had it happen in Maya when the parent transform is += to the child transform because of history

Not sure if that helps or not

As a hack I've fixed it with extra empty parent

Don't know if that works in unity though.

[ashen ferry]

yea idk I shuffled around everything anchors setting position or local position instead of anchoredPosition remade canvas altogether

[wary delta]

Are you using a script to link their positions?

[ashen ferry]

that sensitivity isnt even same when mouse approaches edge of screen it accelerates too im so confused

im changing position of empty element with just rect transform according to how mouse moved

[wary delta]

Show script via pastebin

Are you using the mouse delta?

[ashen ferry]

https://pastebin.com/h0W7BRJh this is full class it goes on ui element which gets dragged around might be a bit messy as its thinking code not actual implementation just started this thing

thing is at the morning when I did that it worked as I wanted I dont know when it started this bs it just did

[timid quartz]

say I have a script attached to a prefab and like 40 copies of the prefab in a variety of scenes, and I want something to affect all copies of that prefab. Can I just make a static method in that script and then call that static method elsewhere and it'll be called on all copies?

I feel like it won't work on unloaded scene copies

[wary delta]

Your calling in update.. multiply your mouse input by Time.deltaTime

[sly lintel]

hello, I am currently trying to activate the children of my parent object through a script in the parent object. I figured out how to reference a variable from an entirely different script but now I am struggling with figuring out how to activate each of the children based on the value of the variable from the other script. How do I go about this?

[versed light]

i really dont know how to setup my code architecture for editor stuff -_- theres no simple way for monobehaviours to subscribe to editor events in edit mode

[summer stump]

Never multiply mouse input by deltaTime.
Mouse input is the amount of movement since the last frame

Dang Brackey! His curse will never leave us! lmao

[wary delta]

Damn lol

How do you get from last pixel then?

[ashen ferry]

ig im going to sleep with this big unsolved

aint no way bruh

always the 2 + 2 = 5 bugs

I seriously doubt my code is the issue

perhaps I repost in ui

[wary delta]

Only for getaxis?

[summer stump]

Only for things that aren't already frame independant.
GetAxis returns a value. For example, GetAxis("Horizontal") returns between -1 and 1 iirc. High framerates will apply that 1 or -1 more often than slow framerates, directly affecting speed. MousePosition is just a position, applying that position quickly or slowly won't change anything, but multiplying it by a small number WILL

So, no, not just for getaxis

[wary delta]

Okay, that was my mistake. So what's causing his transform issue?

[summer stump]

No idea, didn't look 😂

[wary delta]

🍻

[ashen ferry]

cap

bro doenst know either wtf is going on

[summer stump]

took a quick look. I would start by logging both the offset and anchored position.

[wary delta]

Divide your rect width and height by 2

@ashen ferry

[ashen ferry]

Me 5secs ago:

How will that help tho

[wary delta]

Lol do you have a better idea?

Your offset is clearly doubling from the vid you posted and you didn't post the the debug log from offset and anchored position so...

[ashen ferry]

Why ur getting defensive im curious it sounded like a solution

Anyways im off to sleep thats why I didnt reply to aethenosity

[wary delta]

I'm not getting defensive, just thought it might work

[lone sable]

I change my keybind icon during runtime, and I get this weird overlapping. I can fix it by in editor toggling the button on and off again. However, I was wondering if there was a line of code I could run that I'm not thinking of that could fix it/referesh it? I tried LayoutRebuilder.ForceRebuildLayoutImmediate(item); however no luck.

[viral nexus]

If i set my project to use URP i have to restart?

cuz i can't find my pipeline asset

[timber tide]

You may need to create a new renderer asset if there isn't one in your project

[red finch]

hey, I have a unity ragdoll and its floating in the air, I have know idea what i should check for.

[sharp oracle]

Hello I've made a function that basically display a big rectangle (character) and a smaller one (weapon) the function is working well and I've made 2 type of rectangle "white one" and "pink one" (see screen) the problem is I've made a list of big rectangle and a list for the small one but when I press the key r the renderer don't change the "color" of my rectangle I don't know why .https://pastebin.com/c5iXtNzM

[real heart]

CreateBuffers(lod);
        float[] noiseValues = new float[currentBufferSize];

What are buffers ? Are buffers like boxes in which you put your stuff inside ? Also why and when would you need these "boxes" ?

Can't you just put stuff wherever and use it ? Why some stuff requires buffers while other stuff doesn't ? What determines how big the buffers should be ? How do I know if something is compatible with being put in a buffer or not and do buffers come in multiple types and sizes ? Are buffers hardware dependant or can they be whatever ? Do things work faster or slower when using buffers ?

Way too many unknowns for me. Where can I find the answer to all those questions ?

Also I am observing 3 types of what appears to be buffer specific operations: Create(), Initialize(), and Release(). Why do buffers need to be initialized, aren't they initialized when they are created by being put inside the script ? And why would you release them ? And don't you need to put the stuff back then ? I don't see any operations related to "putting stuff back in the boxes".

[teal viper]

It depends on the context. Generally, buffers are arrays of data. And you need to initialize buffers just like arrays.
To answer the rest of the questions we need to know what specific buffers we are talking about.

[polar acorn]

What is the CreateBuffers function? What context did you encounter this in?

thanks let me redo the post

[real heart]

public class NoiseGenerator : MonoBehaviour

    ComputeBuffer _weightsBuffer;

private int currentBufferSize = 0; // Variable to store the current size of the buffer 

public float[] GetNoise(int lod, Vector3 globalOffset)
    {

            currentBufferSize = 0;
        }
    }```

[polar acorn]

Okay, so this is a compute shader.
https://docs.unity3d.com/ScriptReference/ComputeBuffer.html

[teal viper]

Ok, so we're talking about compute buffers. These are basically arrays of data that need to be moved between devices(CPU and GPU), which is why there are specific rules applied to them.

[sharp oracle]

Same question just added the code to pastbin

[polar acorn]

Buffers are essentially packages that can be shipped to your gpu, they have some special operations because you can't just pass whole data to the GPU, the rate is very limited. Buffers can massage the data in ways the GPU can understand to reduce the amount of times you have to do the slow transfer process. Think of it kind of like putting something in one of those special boxes they have at FedEx that are pre-priced, rather than having to weigh and package it yourself and figure out the proper postage for it

A little bit of pre allocation can give some pretty significant speed boosts

[real heart]

So it's like when uploading lots of files to google drive. If you just ctrl+a all the files in the folder and drag them into google drive, the operation seems to take alot of time. But if you archive all those files first, and just drag the archive, the operation seems to take less time. Did I get this right ?

[polar acorn]

Yes actually. A great analogy.

There's a lot of overhead when sending any data, that is the same no matter how big

[real heart]

So basically between the cpu and the gpu there is like a bridge. And you need to send 200 soliders to the gpu. Instead of sending one solider at a time, you pack them all in a big car and send them that way right ? This way you don't have to send one solider at a time and wait for them to arrive and then send the next one and so on. Is this correct ?

[wary sable]

for some reason I cant refrence Cursor in my script, all im trying to do is Cursor.visible = true;

[polar acorn]

Yeah for the one asking the question you seem to have a pretty good grasp of it

You can think of "Create" as making the car, "Initialize" being loading the soldiers in it, and "Release" being letting them all out so you can send another one

[real heart]

Actually, until a few minutes ago I had no ideas what buffers are and I am preparing to read the documentation you guys linked for them. I was just trying to make a high level idea for the moment at least just so that I go about this with the right mindset, so it's thanks to you guys that I have this view on the subject at the moment 😄

[polar acorn]

Do you have a script named Cursor perchance

[teal viper]

I don't see you doing anything with the renderer when r is pressed. Just changing an int variable.

[wary sable]

no

[real heart]

What boggles me about this, is after a buffer gets released, isn't it supposed to be re-used maybe later ? Like what if I want to send another batch of 200 soliders to the GPU, but last time I used the buffer, the last operation was released. So the car is basically on the other side to the GPU. Don't buffers need to be "Called back" to be re-used or does the whole thing run like a loop and I do not need to worry about such things ?

Like does the buffer gets re-created automatically again and "dispatched" again by itself if needed ?

[polar acorn]

So what is the issue you're having with it

[wary sable]

Im not sure, its just not working

[sharp oracle]

Yes but isn't that code ```csharp
if (renderer != null && weaponstypeList[changeweapon] == 2)
{
renderer.material = brownMaterial;
}```` suposed to put "color" to object depending on the if ? because it's the way it work for me

[polar acorn]

It can be re-used, but it doesn't have to be. Even if you make a new car every time you have to send a squad over, it's still better than sending one guy at a time

[wary sable]

Ah apparently I can not use UI.Elements package...

[polar acorn]

You are using UIElements which has its own Cursor class, if you want to use the built in one, you can use UnityEngine.Cursor instead

[sharp oracle]

Like I made a list of color for that reason but if it's the wrong way then I would be happy to know how to do it properly

[real heart]

Got it, thank you very much for all the explanations.

[teal viper]

It can't be reused. On the low level, it's just a reference to the data in the GPU memory. There's nothing to be reused here. Reusing the C# object isn't gonna give any benefit.

Releasing means telling the GPU that that memory is not occupied/used anymore btw. It's more about releasing it on the GPU.

That beings said, you can't send data to the GPU outside of buffers afaik. Even if it's one element it has to be a buffer.

[wary sable]

thank you for the tip, glad to see unity keeping their namespace clean clear and concise

[teal viper]

This would change the material, yes. Let me check your code again.

[sharp oracle]

thanks

[real heart]

Ah, that is great then, it means you can't make mistakes (by not using buffers when sending data to the GPU, cause it's the only way to do it) and things will be usually optimised at least from this point of view right ?

[teal viper]

I don't see that code in this if block:

        if (Input.GetKeyDown(KeyCode.R))
        {
            changeweapon = changeweapon + 1;
            UnityEngine.Debug.Log($"toto a appuyé sur r, la valeur de changeweapon : {changeweapon} {string.Join(", ", weaponstypeList)}");
            UnityEngine.Debug.Log($"toto couleur {weaponstypeList[changeweapon]}");
 
            //if (weaponstypeList[changeweapon] == 1) 
            //{
            //    UnityEngine.Debug.Log($"element actuelle et sa couleur! {weaponstypeList[changeweapon]}");
            //}
 
            //else
            //{
            //    UnityEngine.Debug.Log($"element rooooooooooooooooooooose actuelle et sa couleur! {weaponstypeList[changeweapon]}");
            //}
 
            if (changeweapon >= weaponsList.Count)
            {
                changeweapon = 0;
            }
        }

[teal viper]

Yes. We say "buffers", but it's really just copying memory from RAM to VRAM and keeping track of it. There isn't really anything to optimize.

[sharp oracle]

oh it's when I press p to "make" the "player" should I move it to when I press "r"?

[real heart]

Gotcha, thank you very much for the detailed explanations and advice! 🙏

[teal viper]

Obviously. If you want it to change when you press r, it should be in that if block.

[sharp oracle]

ok let me try it thanks

I got this error:

[teal viper]

Well, debug it. See the line that throws the error and check what is being null there.

[sharp oracle]

it's that line ```csharp
Renderer renderer = weaponsList[changeweapon].GetComponent<Renderer>();

the thing I don't understand is that it "work" on press p but not on press r

[teal viper]

That's why you need to debug - to understand why it doesn't work.
Try using logs or breakpoints to see what is being null.

It's probably the elements in the list.

[sharp oracle]

ok let me see

from what I've understand it only "work" when list index is at 0 but I don't understand why

better print

[summer stump]

What is the debug line? When you say "whole list" what actual value is printed there?

[sharp oracle]

so index is just the index like elem nb 9 of the list current element refer to either 1 or 2 for the color of the object and whole list is just the whole list of color

[summer stump]

Can you include the weaponsTypeList.Count in that?

[sharp oracle]

ok

I don't get it how I got this error while I have the same list on the print and it was working before ```csharp
UnityEngine.Debug.Log($"list index current element of the list and whole list and weaponsTypeList.Count : {changeweapon} '---------' {weaponstypeList[changeweapon]} '---------' {string.Join(", ", weaponstypeList)} '---------' {weaponsTypeList.Count}");

[summer stump]

@sharp oracle You wrote weaponsTypeList instead of the previous weaponstypeList

my fault for writing it that way

I missed that you had a lowercase on the second word

I DO recommend going by standard c# naming conventions, but you can do what you want as long as you stick to your style
https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/coding-style/coding-conventions

[indigo wadi]

Hi, I'm new using Unity and i'm still learning how to write code in C#, and doing a school work for mi programation class this isn't working, Can someone help me plz? Testing different things I reach to the conclusion that the part isn't working is "void OnTriggerEnter (Collider other)" and I don't know how to fix it. (English is my second language, so sorry for any grammar mistake, thnks)

[sharp oracle]

oh I see no problem

[sharp oracle]

I will fix my bug then fix the whole naming convention

[summer stump]

you see no problem?
Types vs types
case matters. Those two words are completely unrelated in the eyes of the compiler

[summer stump]

fair

[sharp oracle]

no I meant about your mistake

[summer stump]

Does one of the colliding objects have a non-kinematic rigidbody attached?

[sharp oracle]

I understood the problem I just copy paste withouth re reading

here is the print

[summer stump]

Ohhh, understood

[sharp oracle]

Is my error linked to an non existing elem on weaponstypeList ?

[hot hinge]

can someone please help me in unity talk

[indigo wadi]

Nope, they only have Transform, SpriteRenderer, Colliders, Animators and scripts

[summer stump]

Then it won't work. OnTrigger REQUIRES a non-kinematic (dynamic) rigidbody on one object

[teal viper]

Yep. Most likely. One of the elements is null.

[sharp oracle]

but when I print the list none of the element is null

[summer stump]

Hmm... also, it's a list of ints, which can't be null. But... something is going on.
What is the actual code on line 81? The line causing the error
Is it this:
#💻┃code-beginner message

Because then the null would be in the weaponsList, not weaponstypeList
Debugging the latter wouldn't help find the issue in that case

[indigo wadi]

I added a dynamic rigidbody 2d to the bullet and the enemy and still doesn't work :/

[summer stump]

So, one object has a non-trigger collider, and the other has a trigger collider?

Oh, it's a bullet.
Is it going fast? Is the bullet collider small?

Are you moving it by "teleporting"
(transform.position += whatever)?

Sometimes it can simply teleport past the collider without actually colliding

[teal viper]

It would be safer to step through code with a breakpoint. Or break on error and inspect the relevant objects in the inspector. You can enable debug inspector to see private fields.

[sharp oracle]

thanks, how do I enable debug inspector ?

[indigo wadi]

yes, the bullet has a "is trigger" on, should I set it off to make it work?

[summer stump]

No, one has to have it

[teal viper]

Click the three dots at the top right of the inspector

[summer stump]

Does the OTHER object have it set to trigger?

[indigo wadi]

nope, the bullet is big and the collider too and i can see it travelling on the screen so i think it isn't going fast

[summer stump]

Well, I would go through this:
https://unity.huh.how/physics-messages/2d-physics-messages

[indigo wadi]

nope

[summer stump]

You have the building blocks for it then. Might be another issue

[sharp oracle]

I now got this

[ivory bobcat]

The first is likely a false positive (or maybe it's real - internal). The others insist that you've got a reference to null and attempting to use it.

[sharp oracle]

oh I see so what do you think I'm doing understand

I tried to understand since but I don't find it

#💻┃code-beginner message

You are printing the wrong list

[sharp oracle]

Oh I'm dumb as fuck

result

code line ```csharp
UnityEngine.Debug.Log($"list index current element of the list and whole list and weaponsTypeList.Count : {changeweapon} '---------' {weaponsList[changeweapon]} '---------' {string.Join(", ", weaponsList)} '---------' {weaponsList.Count}");

[ivory bobcat]

Result of what?

[sharp oracle]

pressing r

[teal viper]

There's like 5 sec between the error and the log message. What's going on?😅

[sharp oracle]

I just press key r

[teal viper]

So does the error come out when you press r or before that? I feel like you're hiding something

[sharp oracle]

I first press key p to "make" the player and little rectangle this work fine but when I press r the error occure

not before

[ivory bobcat]

The two did not occur back to back

[teal viper]

So when does the debug log print?

[sharp oracle]

just tried right now

[sharp oracle]

when I press r

[teal viper]

Ok, so it comes before the errors.

Which doesn't make sense.

[ivory bobcat]

You should move the log before the error line 81

[teal viper]

Unless you changed the order in your code.

[sharp oracle]

ok

[ivory bobcat]

I'm guessing element 0 is valid whereas none the rest are.

[teal viper]

Ah, I guess that makes sense.

[ivory bobcat]

Where the first successfully logs and the rest just blows up with an error

[sharp oracle]

I've made it like this

[summer stump]

The debug line isn't showing the whole line. I'm interested in the count

[sharp oracle]

oh

[ivory bobcat]

Can you show the entire updated code from a link?

[sharp oracle]

yeah

https://pastebin.com/QjHbHCnT

[teal viper]

Really hard to read with all these dashes, but it seems like the elements after 0 are null.

[sharp oracle]

do you want me to make a better "print"?

[teal viper]

No. Id prefer you to just look at the object in the debug inspector as I suggested half an hour ago. And take a screenshot of it.

[sharp oracle]

I have but It's not that understandable

[north kiln]

Why does it also say NewBehaviourScript

[ivory bobcat]

You've only got one weapon in the list

[sharp oracle]

let me add more weapon

wait isn't that supposed to fill the list ? ```csharp
private void Awake()
{
// Appelé avant le Start, souvent utilisé pour initialiser des variables
// Générez un nombre aléatoire entre 1 et 2 pour WeaponType dans Awake

    for (int i = 0; i < 3; i++)
    {
        WeaponType = UnityEngine.Random.Range(1, 3);
        weaponstypeList.Add(UnityEngine.Random.Range(1, 3));

        if (WeaponType == 1)
        {
            weaponsList.Add(spawnedEntity);
            weaponstypeList.Add(1);
        }
        else
        {
            weaponsList.Add(spawnedEntity);
            weaponstypeList.Add(2);
        }
    }
}   

[north kiln]

weaponsList and weaponstypeList are different lengths

I also have no idea what that if statement achieves

[sharp oracle]

that's true

[north kiln]

It's generally bizarre code that is unclear to me, doesn't help that I can't speak french 😄

[sharp oracle]

just to make different "colour"

[sharp oracle]

I know my code is bad as hell it's my fault there

[north kiln]

Yes but you could just write:

weaponsList.Add(spawnedEntity);
weaponstypeList.Add(WeaponType);

[sharp oracle]

I just removed the first add on the weapontypelist

now they should have the same lenght

[summer stump]

Are the lists supposed to be matched? Could the weapon just have its own type as a property?

[north kiln]

There are two other concerns

You are not printing weaponTypeList.Count in that log statement

you print changeweapon

[ivory bobcat]

I'm assuming his nre is solved now

[summer stump]

It is printed later, just cut off there haha

[sharp oracle]

yes my first goal was just to make 2 different color to make like "2 different weapon" then I found out that doing the render was making the "color" pink and it was fine for me so I stayed with that option

[north kiln]

They print weaponsList.Count, it's a mess

Regardless, the error is an NRE, not an index out of range, so none of the prints matter, no?

[sharp oracle]

yes I was printing the wrong list since like 30 minutes

[ivory bobcat]

Consider having a struct hold the pair weapon and type in a single list to not have two lists.

[timid quartz]

how would I in script un-check these check-boxes? I know I can Get Component but then how do I make them inactive?

🪲 To make bug reporting as quickly as possible, we made a bug reporting application for you. When running Unity choose Help->Report a Bug in the menu, or you can access it directly through the executable in the directory where Unity is installed. It will also launch automatically if you experience a crash.

📝 If your bug report is to do with Documentation, either an error, typo, or omission, you can report it by scrolling to the bottom of the page where you found the issue and click ‘Report a problem on this page’!

💡If your report is to do with a new feature idea, you can check the Unity Product Roadmaps page to see if your idea has already been planned.

For more complete instructions on how to report bugs, access: https://unity3d.com/unity/qa/bug-reporting

You've only got one weapon according to your old logs.

[sharp oracle]

yes just saw that by doing test myself

but how I get only one weapon but the len of my list isn't one ?

[ivory bobcat]

Orange indicates the null elements. Blue including commas were the elements in the list - notice the blanks between commas.

Green were valid elements which only occurred with element zero

It would be much easier to use the debugger than endlessly iterating on these print statements

[sharp oracle]

thanks

[sharp oracle]

I know but what is this supposed to mean ?

[north kiln]

The script asset is totally irrelevant and you rarely need to look at it

[cosmic dagger]

why are you looking at the actual script asset file?

[sharp oracle]

isn't that debugger ?

[ivory bobcat]

They meant IDE debugger

[sharp oracle]

that ?

[ivory bobcat]

Where you'd attach the process and include break points..

Visual Studio debugging

[sharp oracle]

oh

thanks

[north kiln]

It is always worthwhile to learn https://www.youtube.com/playlist?list=PLReL099Y5nRdW8KEd59B5KkGeqWFao34n as it will save you so much time over logging

[sharp oracle]

thanks

after looking searching and struggling I've understand exactly what isn't working

it's that ```csharp
weaponsList.Add(spawnedEntity);

the spawnedEntity I'm adding to my list mean "nothing" to it so it's make like it's not there

[north kiln]

If spawnedEntity was null it would only cause an error when it was accessed, and that line does not access it

[sharp oracle]

I see

[teal viper]

It is the debug inspector but you're looking at the wrong thing. You should look at the script in the scene on the GameObject. The one that throws the error.
What you show on the screenshot is a script asset, not it's instance.

[teal viper]

Is spawnedEntity being null?

[sharp oracle]

I think so , when I print elem 2 so weaponsList[1] it print nothing

[sharp oracle]

I'm currently inside the debug mode of vscode I've added breaking point link to my function but I'm either dumb or idk but it just give this

[teal viper]

Nothing means null. I really suggest to go over the c# basics to understand reference types and null.

[teal viper]

It doesn't look like it has been triggered yet.
Is your debugger connected to unity?

[sharp oracle]

normally yes

[summer stump]

You should not have it attached unless you are actively debugging. Also, what you showed above here
#💻┃code-beginner message

Is not having the debugger attached

In the top middleish of visual studio it shows "attach debugger"

[hearty ivy]

Can anyone help me with sorting layers for a topdown 2d game

how can i make all my sprites in my sprite sheet pivot without breaking everything

i think that is my problem

the sprite sheet is my player sprite sheet so

[wary sable]

Hello, I am trying to make an inventory system and was making a method to add armor and weapons to lists for 'currently equipped'. I have two classes, Weapon and Armor, which both extend an Item class. I wanted to use one insert method to simplify and add more scalability to my system. Currently I have: private void EquipItem(Item item) { if(item is Armor) { equippedArmor.Add(item); } else if(item is Weapon) { equippedWeapons.Add(item); } }
Which isn't working because item is defined as an 'Item' is there any way around this?

I also cant make Item an interface since it has monobehavior methods inside it

[patent portal]

Curl error 56: Receiving data failed with unitytls error code 1048578 what kind of this error?

[timber tide]

If these objects derived from item, I would assume this would work, no?

[wary sable]

thats what I assumed would happen, but that doesnt seem to be the case

[timber tide]

Strange, well, you can always add like an enum for weapon/armor then assign their type inside of their own respective class and instead check that

[north kiln]

Don't cross-post.

Nobody knows the context, elaborate by mentioning what came up when you searched about it

[wary sable]

how would I remove an element from an array without resizing?

[timber tide]

arr[i] = null

[wary sable]

alright, is there a way to do it by object instead of indice?

said objects are not primitives*

[timber tide]

Like, clean up an object entirely? You don't really use deconstructors in c#, so if you want an object to be collected by the garbage collector, you'll need to remove all references relating to it.

[wary sable]

I moreso meant something similar to List.Remove(myObject) so I wouldnt have to use a loop or lambda to remove it from the list.

[north kiln]

IndexOf and then setting that index to null

[timber tide]

ah, right

[north kiln]

Though you've really got to question why you're using an array

[wary sable]

using it for an inventory element displaying armor / weapons (2 different arrays). Since there is a limited number of slots for armor and weapons I figured an array would be best since I could easily limit the size without having to add a bunch of checks

[wary sable]

Its not a big deal if I have to, this is more out of curiosity at this point

[queen adder]

How many slots?

[timber tide]

That's fine if you're not extending your inventory at all

[wary sable]

currently 5 and 4 respectively

[queen adder]

Then just use a struct

[wary sable]

yeah the inventory is a seperate list, these lists are just for the slots
