[quartz grove]

And godot ?

[rich adder]

so you think thats an essential feature to have ?

[summer stump]

No idea. Tried it and didn't like it

Pretty sure it's FOSS though?

All of this is very googleable though

[rich adder]

Still unclear what you're asking on what the problem is tbh

[summer stump]

The themes are what the editor looks like. Like themes for Google Chrome or Firefox, where the background and buttons looks slightly different.

It's a big nothing-burger

[quartz grove]

Gotcha

[polar acorn]

1. The position of the transform
2. How many elements the vector has

Oh, I was scroll locked and we've all moved on, nevermind

[cosmic dagger]

happens to me all the time, i hate it . . .

[quartz grove]

Oh 0 dollar u will pay , tbh thats really good

[crisp token]

does .equals in java for two objects not just compare their members? It seems like its doing something else

[rich adder]

java?

[crisp token]

yeah, for a server

[cosmic dagger]

wrong server?

[rich adder]

perhaps ask in java server lol

[rare basin]

you're in Unity, C# server mate

[crisp token]

well its for unity kind of

[rich adder]

Im using Microsoft's version of Java

[rare basin]

how come

you dont programm in Java in Unity

[crisp token]

I have a database server for my unity pvp game

[rare basin]

still not related to unity

your server code != unity code

[crisp token]

its a simple question iwas looking for a quick answer thats all

[rich adder]

then ask in a java server?

[polar acorn]

There's not too many people who know java here

[crisp token]

oh ok, thanks

[rare basin]

i found a answer to your question

in google

in 10 seconds

[polar acorn]

But I'm pretty sure it's a full reference-equality unless you override it

it'll return true if two objects are literally the same object

[crisp token]

I looked that up but they all say that .equals compares contents vs == compares reference but I dont think thats true

i mean i proved its not true

[cosmic dagger]

you broke java? 🤯

[pallid nymph]

equals is a custom implementation, it can compare whatever

== does a ref equals

or so I'd assume

[crisp token]

loading two small classes into pastebin ill show

[polar acorn]

This is probably a question for a java server

[rich adder]

why not just make your server in c#..

[polar acorn]

if it's going to require looking at code

[crisp token]

ik some people sounded curious thats all

[quartz grove]

u know what i ll just go with unity

i like the icon

[crisp token]

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

[short hazel]

== compares by reference in Java. For strings, you use .equals() to compare the value. C# has no such restrictions because, unlike with Java, operator overloading is allowed

So each type could implement its own behavior for most operators

[crisp token]

So are you saying when you call .equals() on two objects it's using the == operator on each member indiviudally?

[frosty hound]

@crisp token Make a thread, this topic isn't related to this channel.

[rich adder]

why not just make the server in c# lols

[buoyant knot]

i’m prettt sure C# lets you == with strings pretty well

strings are not a reference type in C#

[hearty trout]

I found a tutorial that explains the system in great detail but ima need to still learn alot other stuth so thank you for all the feedback and I am going to reconsider jumping straight into my dream game @rich adder

[rich adder]

are they not?

[short hazel]

They are

[rich adder]

are they not just arrays of char

oh ok

[scarlet skiff]

i cant figure out how to do the layer thing correctly, my animations are being weird

[buoyant knot]

what. i thought they were value type jn C#

[rich adder]

negative

[static bay]

Strings?

Nah they're immutable reference types.

[rich adder]

immutable types

[static bay]

Trust you do NOT want value type strings.

[crisp token]

what's an immutable type?

[static bay]

Can't be changed. Immutable.

[crisp token]

so what would be a mutable type

[static bay]

As opposed to Mutable, wich can be changed.

[queen adder]

Let's check the docs

[rich adder]

a type that can be changed?

[shell sorrel]

you can'd modify the string in place only replace it, but its a reference

[queen adder]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/reference-types

[crisp token]

what do you mean when u say changing a type. Like reassigning their value vs replacing w/ new object?

[buoyant knot]

i feel like i’ve been lied to

[shell sorrel]

string can't be a value because well that would be a lot to pass around, and also its length is not knowen

[queen adder]

Strings are normally allocated on the heap in most languages?

[shell sorrel]

like a int we know is always 4 bytes

a string who knows

[rich adder]

string str = "Hello";
str[0] = 'h'; ```

example you cannot do this

[static bay]

Nah. Imagine how bad that'd be if they were a value type. Every time you'd pass it into a function you'd generate a copy. Considering how MASSIVE strings can get, it's asking for trouble.

[rich adder]

you have to replace the whole string

[shell sorrel]

the bigger issues is sizing

[short hazel]

Equality check for strings in C# does the following, in order:

1. Do they point to the same area in memory?
2. Is either of them null, or do they have a different length?
3. Each character is converted to a byte and efficiently compared with SpanHelpers.SequenceEquals() (which does not allocate)
   Source

[buoyant knot]

that’s why I would try to exclusively use stringbuilder for big strings. I thought they were value type 😂

[rich adder]

still good practice to do so

[static bay]

Agreed

[queen adder]

Yeah everyone says use StringBuilder or the Span<> type

[shell sorrel]

stringbuilder for building larger strings is mostly about allocations

but yeah would use it if building a large string out over time

[buoyant knot]

ref type does make more sense. i just thought the people who made C# had the same stroke of genius as the guy who made Mathf a struct

[static bay]

Actually stringbuilder is for babies. Real men don't need some so called "builder" and just do raw +.

[rich adder]

lol

[polar acorn]

Galaxy brains use String Interpolation

[shell sorrel]

was supprised it was a struct and not a static class

not that it matters, think it only has constants and methods

[buoyant knot]

and also decided it would be okay for arrays to implement IList, despite arrays lacking the major things that make a list not an array lol

[rich adder]

StringBuilder sb = new StringBuilder();
        sb.Append("Hello");
        sb[0] = 'h'; // mutable```

[queen adder]

Mathf has a lot of static methods and fields I wonder why it isn't a static class?

[quick edge]

I'm gonna ask again my question, because I think I explained it the wrong way. What I want is to be able to do something over x amounts of time. Example, over 10 seconds I want to be able to move, during these 10 seconds I can move but after the 10 seconds I can't. How can I achieve that ?

[buoyant knot]

because the guy who wrote it was drunk

[quaint crystal]

hello. does doing this only remove the reference from the array? so if i want to delete a dog i should use Destroy()?

dogArray.RemoveAt(0)

[static bay]

Wait it... isn't.

[shell sorrel]

a quick look at it, everything is const or static

[static bay]

Waaaat?

[rich adder]

two different things

this only removes it from list not destroy it ( the item)

[buoyant knot]

he envisioned a world where you want to have a couple of different instances of Mathf

[quaint crystal]

so i need to remove it from the array and then destroy?

[buoyant knot]

yeah, Mathf is a struct

[rich adder]

destroy obj first then remove from list

[polar acorn]

RemoveAt simply removes a thing from the collection

[rich adder]

otherwise you have no reference valid

[static bay]

Same guy who made Random static decided to make Mathf a struct.

[quaint crystal]

thank you

[buoyant knot]

Random isn’t static tho

System.Random is not static

[static bay]

Unity's Random is

[queen adder]

The Unity namespace has a Random class to

[cosmic dagger]

the Unity version . . .

[queen adder]

I get that fucking conflict all the time

[buoyant knot]

idk, I only use System.Random lol

[queen adder]

Are they not the exact same thing?

[shell sorrel]

i like the system one when i need to control the seed

but the unity one has very useful stuff for games on it

like unit vector values

[edgy prism]

Hello ChatGPT has assured me that this function will loop until fishCaught is true based off of coroutine functionality, but its not working for me rn so I just wanted to double check cause im doubtful

public IEnumerator StartFishing()
    {
        bool fishCaught = false;

        if (UnityEngine.Random.Range(1, 101) <= 10)
            fishCaught = true;

        while (!fishCaught)
        {
            yield return null;
        }

        GameController.Instance.StartBattle(BattleTrigger.Water);

    }

[shell sorrel]

insideUnitCircle and insideUnitSphere for example

[rich adder]

#📖┃code-of-conduct

[quick edge]

Can someone help me on this please ?

[rich adder]

we should have a rule, do not fix broken gpt code 🙄

[shell sorrel]

well the loop part is doing nothing

[queen adder]

ChatGPT is not the end all of stuff being certain

[buoyant knot]

and did ChatGPT write it for you?

[edgy prism]

No

I wrote it myself

[shell sorrel]

essentially it tries to catch fish once and if that fails it loops doing nothing forever

[buoyant knot]

then why are you asking ChatGPT a question about something which it does not understand

[static bay]

Nah. I don't exactly know if the actual implementation of the random number generation is different, but Unity's has a lot of extra methods that're more "game dev" appropriate.

[frosty hound]

That code will result in an infinite loop

[edgy prism]

Right yeah let me go check what ChatGPT does and doesnt understand before I run it by it

[buoyant knot]

also, this is definitely an infinite loop

[rich adder]

luckily not the one that crashes, the function will just run forever

[shell sorrel]

you have to learn how to program GPT will not do that for you

[low path]

wasn't there somebody in here before saying how chatgpt was amazing for code comprehension, and good for juniors or s/t?

[buoyant knot]

ChatGPT doesn’t understand anything. It works by a syntax-based language model

[rich adder]

feels like it happens almost 1-5 people

[buoyant knot]

it cannot explain, as it does not know

[shell sorrel]

anyone with a bit of experience can look at that code and see its broken and not working to intent in half a second

[edgy prism]

So the bit I was curious about is how I can get it to generate a random value until it gets one that sets the fishCaught bool to true is my only option to use Update?

[queen adder]

It's good at explaining things. You can't make an entire game from chatGPT if u don't understand how the unity editor works and C# on a deeper level

[rich adder]

you put it inside the while loop with a sort of Time Between tries.

[edgy prism]

Ok so next time just say dont use ChatGPT cause I dont like it

[buoyant knot]

it’s good at making convincing explanations. as to whether or not the explanation is true, that is a different story

[shell sorrel]

just think about what the code is doing line by line

it can be done in many many ways including a coroutine

[buoyant knot]

I like chatGPT. But not for coding lmao

[polar acorn]

If you want it to generate in the loop, it'd probably make sense to generate it in the loop

[edgy prism]

Ah yeah im an idiot

[rich adder]

my lovely secretary 😈

[frosty hound]

Stick your random number generation inside of the loop. Then you can yield some time between checking if you don't want it to be instant.

[shell sorrel]

also whole thing can be simplified if you are just wanting to wait till you catch a fish

since then its really just about a random wait duration no loop needed

[edgy prism]

Good idea, So just to check whilst im on the subject yield returning a coroutine starts it over from the beginning it doesnt return to the point it stopped at last time?

[rich adder]

var time = new WaitForSecondss(timeBetweenChecks);
while (!fishCaught)
        {
          if (Random.Range(1, 101) <= 10)
            fishCaught = true;
            yield return time;
        }```

[buoyant knot]

yeah, you just generate a random wait time, and yield return new WaitForSeconds(thatTime);

no while loop involved

[shell sorrel]

yield return new WaitForSeconds(Random.Range(minWait, maxWait));

[frosty hound]

It doesn't start it from the beginning. It just waits that amount of time before going to the next line. In your case, the next line would be at the top of the loop.

[rich adder]

much better for gameplay with some rng

[edgy prism]

Hahah yeah I never even thought about that

Ok thanks for your help everyone

Add goes on the end

if you want to insert into a spot there is a method for that

[low path]

the docs tells you how add works

[rich adder]

Insert()

[cosmic dagger]

you cannot add to an array . . .

[shell sorrel]

also assuming you mean List

[cosmic dagger]

if you add to a list, it goes on the end . . .

https://paste.myst.rs/v0zv5q29

[summer stump]

If you are dragging it in via the inspector, do not do GetComponent
That overrides the reference

Is the audio source on the SAME object as that script?

If not, it is returning null

[rich adder]

you might be passing null to the AudioSource, if issue was with AudiSource it would give NRE (or log the error from awake actually)

[uncut dune]

grab layer is a layer mask and I aint sure why it always gets my playwer which is on the default layer

[short hazel]

The error is a bit misleading for this one, it's the audio source that's null. In other conditions this would report a NullReferenceException, but due to how AudioSource is made internally, it's the ArgumentNullException that is thrown.

[glossy sierra]

what would be the best alternative? i m a beginner so i couldn't understand

[summer stump]

A layermask is not a layer

[summer stump]

Remove GetComponent completely

[rich adder]

what about this though

   private void Awake()
        {
             audioSource = GetComponent<AudioSource>();
    if (audioSource == null)
    {
        Debug.LogError("AudioSource component not found on the player GameObject.");
    }```

[glossy sierra]

tried this i m getting log error

[short hazel]

Not related, the error occurs on line 450+

[uncut dune]

before I had just a RaycastHit2D with a layermask but it always got my player

it made no sense

[rich adder]

wait they have another audiosource

nvm

[summer stump]

Show what you set the layermask to

But your layer == grabLayer makes no sense if it is a layermask

[summer stump]

Open it

Or uncollapse it, or whatever

[uncut dune]

like this it used to get the player

as w ell

[craggy oxide]

its useful but ONLY in very small doses
it can give you 100% accurate help with 1 or 2 lines of code
if you ask it to do a lot of the work it's going to make mistakes or do it in a weird way

[short hazel]

The arguments are not correct. You're passing the mask in lieu of the distance. It's origin, direction, distance, mask

[rich adder]

so its logging error ?

[summer stump]

I don't see an overload where layermask is third
Edit: ah yeah, as spr2 said

[uncut dune]

but do I need a distance?

[glossy sierra]

NullReferenceException: Object reference not set to an instance of an object
StarterAssets.ThirdPersonController.PlaySound (UnityEngine.AudioClip clip) (at Assets/StarterAssets/ThirdPersonController/Scripts/ThirdPersonController.cs:477)
removed get component still getting this

[summer stump]

You NEED to use the correct parameters in the correct order

[uncut dune]

its Mathf.Infinity

[short hazel]

It defaults to Mathf.Infinity. So pass that, or use a named argument to just pass the mask

[summer stump]

If you use something past an optional parameter, it becomes required

[uncut dune]

OHHHHHHH

[rich adder]

why would you remove get component if you did not assign it anywhere else ? including inspector

[summer stump]

Unless- yep spr2 beat me to it

[uncut dune]

never knew that

[rich adder]

if you dont care about order, use named parameters

[short hazel]

.Raycast(transform.position, Vector2.right, layerMask: grabLayer)

[summer stump]

You said you drag in the source via the inspector
You need to do that if you are removing getcomponent

[uncut dune]

thank you guys!

[rich adder]

if(Physics.Raycast(direction:mydirection etc.
you can put them in any order this way

Does anyone know how to get rid of this

[trail heart]

What is "this"?

[polar ermine]

Graphics on this texture is buggy

[polar acorn]

Buggy how

it looks pretty normal to me

[polar ermine]

Graphics is a bit jagged when player move

[timber comet]

its honestly barely visible

[polar ermine]

On a larger screen its more visible

[swift crag]

Video compression will mangle it pretty badly.

Are you talking about the patterns towards the end of the walkway?

[trail heart]

@polar ermine Enable mip map generation on the texture, with trilinear filtering if it still looks bad

[swift crag]

yeah, trilinear filtering will blend between mipmaps

[north kiln]

Weird code question

[polar ermine]

Trilinear filtring is on ill try with mip mapping

[swift crag]

it is, indeed, a weird code question!

[north scroll]

In unity, is one Canvas gameobj usually how UI/images are added, or should I have multiple canvas for each item, examples: Timer, Boss Health bar, player mana bar, etc

[polar acorn]

Whenever one element on a canvas needs to be redrawn, the entire canvas needs to be redrawn. You should try to find a balance between having too many things on one canvas such that redrawing becomes slow, and having too many canvases which makes for a lot of object overhead

If you can find decent ways to compartmentalize it, go for it. Just don't go nuts

Does the object with this script have a rigidbody?

Or the wall?

[south fjord]

The object does

[summer stump]

Put a debug.log just inside the OnCollisionEnter enter to make sure that is being called

Wait

Each time it collides you do that for ENTIRE loop

[short hazel]

Also why the for loop? It's going to be executed in one go so you won't see anything happening

Frame gets rendered -> 40 loop iterations execute -> next frame gets rendered

[quick pollen]

How can I move something towards a position without verticality?

[south fjord]

It's for a exam, they want it move between the walls exactly 20 times, so I thought 20 for each wall i.e. 40

[summer stump]

That is not how you would do that at all

Remove the for loop

[short hazel]

That's not how it works yeah

[summer stump]

Increment a class variable

[short hazel]

You need to keep track of the count in some variable

[limber narwhal]

is there a different type i can use instead of float because for 0.10 I get Subtracting 0.09999999 from score when I use Debug.Log

[rich adder]

int

[limber narwhal]

int will work with 0.10 ? 🤔

[rich adder]

no

decimal would

but why that for score instead of int, curious

[short hazel]

You'll most likely want to keep the value as a float, but format it if you plan on displaying it to the user

eg. Debug.Log($"Subtracting {score:F2} from score") - "F2": format string for a float with 2 decimals. Adjust the number after the "F" to show more or less. The number is automatically rounded.

eg.2 someText.text = score.ToString("F2")

[limber narwhal]

it's just that i have a conditional that compares previous balance/score with the new one and I get something like Score changed to 9936.7 from 9936.701 but in reality nothing changed

it's because when i subtract .10 its actually subtracting 0.0999999999 or w/e i think

[short hazel]

Yes because of floating point precision errors. In that case you can subtract the two numbers and compare them to some other small value to see if they're roughly identical

if (Mathf.Abs(a - b) < 0.01)

[rich adder]

isnt there also mathf.approx

[limber narwhal]

oh that's pretty smart thanks i didn't know about that

[north kiln]

Try to write a number in here and note it often cannot be represented https://float.exposed/0x461b42cd

[south fjord]

So I've tested around, it works with a variable and also the code Aethenosity sent, but now it gets stuck on the other wall (-x) instead

Make sure your IDE is configured before you go down any other python-esque rabbitholes

[quartz grove]

ok ok we starting i ll make snake game

[quartz grove]

Ok

[potent glen]

should i learn C# and unity at the same time or should i start learning C# first

and if the latter, to what extent should i know C# before starting unity

[frosty hound]

You can do both

If you want to do C# specific learning, just start with the basics really.

[rich adder]

you can do both, easier to probably do c# first alone with Console apps because its no extra APIs and compiles quick

[limber narwhal]

i ended up making a little helper method like this based on some more google searching:

    private float RoundedFloat(float value)
    {
        return Mathf.Round(value * 100f) / 100f;
    }

[polar acorn]

I'm not sure what you're hoping to accomplish with this

that's probably just gonna introduce more imprecision

[limber narwhal]

so far it works , but now i'm paranoid from your comment and gonna keep testing it until it doesnt lol

[polar acorn]

It's important to realize that something like 0.01 isn't becoming 0.00999999, it is 0.00999999. That's just how that particular value is represented in floating point. If a value can't be represented exactly in float, then you're not going to "trick" the code into being able to represent it

[limber narwhal]

i kind of understand what you mean

so the 0.099999999 is the correct number

[naive lion]

Hey guys half AI half general coding question here
How would I approach a system where if you alert one enemy, all enemy classes/types also become alert of the player

[limber narwhal]

so the other one that isn't 9367.701 is wrong 🤔

[polar acorn]

As far as floating points are concerned, yes

[rich adder]

invoke a static event

[polar acorn]

Have something that holds a reference to every enemy, and that every enemy has a reference to. Have that enemy tell that central object "I saw this guy" and have that object push out the notification to all the other enemies

A good way to accomplish this is with an event listener.

https://gamedevbeginner.com/events-and-delegates-in-unity/

[naive lion]

great thank you
will look into it
need to start digging into events, been avoiding them for no reason but procrastination

[polar acorn]

Once you learn how to do them you'll start putting them everywhere

[tender stag]

how can i increase the gap which the header attribute makes in the editor

is it possible through like preferences in the editor?

[timber tide]

if I'm trying to sync rotation with another object but with a offset is adding that rotation directly workable or should I grab the axis information the first object rotated on

[rich adder]

if you want bigger gaps just put [Space(amount)]

[Header("Hello"), Space(30)]

[tender stag]

i mean yeah but i was wondering if i can change the amount of space header makes

    //keep the camera inside the bounds

[tender stag]

alright thanks

[old ibex]

I just sent a snippet I can also send the full script

[rich adder]

which line is 37

[old ibex]

although I doubt it will help

[summer stump]

Since it's lateUpdate, it may just be happening after the scene is unloaded. You could do what the error suggest and just check if it is null first

[old ibex]

transform.position = new Vector3(target.position.x, target.position.y, transform.position.z);

[summer stump]

The first one, there is a comment

[rich adder]

oops just seen comment 😅

yeah you could just put a null check

[old ibex]

so inside lateupdate I would check if the transform is null, and if it is then do the same line of code again?

[rich adder]

your code must be running while obj got destroyed for scene change

[old ibex]

yeah and I tried DontDestroyOnLoad(gameObject); but it didnt work

[rich adder]

top of the LateUpdate
if(target == null) return;

[old ibex]

let me try that real quick

[winter frost]

Hello everyone! Please, can someone tell me why there is a error in the array? Thank you.

[rich adder]

just use cinemachine and u get a better camera and not worry 😛

[rich adder]

jesus christ

ever heard of an array

oh you did since you're using it on the line that errors..

thats not how you init an array

[winter frost]

Ok. How can I do it then?

[rich adder]

just make your Modulos a SerializeField array and assign them in inspector
if you are using numbers for variables, you need an array.

[old ibex]

ok so by adding the line of code you told me, the error went away, but now the issue is that I added a fadeScreen which fades when there is a scene change. That fadeScreen is fading into the scene, but it does not fade out, so I am stuck on a black screen

[winter frost]

Ok, thank you very much 🙂

[rich adder]

I can't guess , you have to provide proper context like the code and setup

[timber tide]

[SerializeField] private GameObject[] ModuloList;``` (Actually you dont want to new it, just add them on the inspector)

Can just serialize the array and add more entries on the inspector

[old ibex]

so basically I have an image in the canvas and its alpha value changes via a script I made:

        if (shouldFadeToBlack)
        {
            fadeScreen.color = new Color(fadeScreen.color.r, fadeScreen.color.g, fadeScreen.color.b, Mathf.MoveTowards(fadeScreen.color.a, 1f, fadeSpeed * Time.deltaTime));

            if(fadeScreen.color.a == 1f)
            {
                shouldFadeToBlack = false;
            }
        }

        if (shouldFadeFromBlack)
        {
            fadeScreen.color = new Color(fadeScreen.color.r, fadeScreen.color.g, fadeScreen.color.b, Mathf.MoveTowards(fadeScreen.color.a, 0f, fadeSpeed * Time.deltaTime));

            if (fadeScreen.color.a == 0f)
            {
                shouldFadeFromBlack = false;
            }
        }
    }

    public void FadeToBlack()
    {
        shouldFadeToBlack = true;
        shouldFadeFromBlack = false;

    }

    public void FadeFromBlack()
    {
        shouldFadeToBlack = false;
        shouldFadeFromBlack = true;
    }

The script is called whenever there is a scene change

so now when the scene changes, it fades to black, but doesnt fade back from black

I have an area entrance and exit system

In which I manage the scene changes and which scene to change to etc

Area Exit:

    void Update () {
        if(shouldLoadAfterFade)
        {
            waitToLoad -= Time.deltaTime;
            if(waitToLoad <= 0)
            {
                shouldLoadAfterFade = false;
                SceneManager.LoadScene(areaToLoad);
            }
        }
    }

    private void OnTriggerEnter2D(Collider2D other)
    {
        if(other.tag == "Player")
        {
            //SceneManager.LoadScene(areaToLoad);
            shouldLoadAfterFade = true;
            GameManager.instance.fadingBetweenAreas = true;

            UIFade.instance.FadeToBlack();

            PlayerController.instance.areaTransitionName = areaTransitionName;
        }
    }

Area Entrance:

    void Start () {
        if(transitionName == PlayerController.instance.areaTransitionName)
        {
            PlayerController.instance.transform.position = transform.position;
        }

        UIFade.instance.FadeFromBlack();
        GameManager.instance.fadingBetweenAreas = false;
    }

[rich adder]

do you know for sure this script is actually running after it fades into black

[old ibex]

yes

I have tested it out before and it works, nothing breaking

Now its giving me an issue for some reason

[rich adder]

before what ?

[old ibex]

Before I had the other issue of the Transform being destroyed

[lusty flax]

i'm trying to make it so my spikes in my game are placed in a grid-like way (easily). can I achieve this using a gridmap? whenever I try to set the pixels per unit, it doesn't work as the image's x and y scale isn't the same. how can i do this?

[rich adder]

do you have any other errors in console?

[old ibex]

I am getting a warning over and over, which says that There are 2 event systems in the scene

im not sure how to fix it, and its probably why everything else is not working

[rich adder]

ur probably referencing a different screen then

not sure

[rich adder]

dont think this warning would affect the code you have

but still you should fix it, delete one of them

you mention DDOL somewhere earlier, its probably causing multiple issue if you have no disposed the other properly

[old ibex]

Im not sure what an Event System even is, would you be able to tell me how to get rid of it?

Oh my bad sorry

I just realized it is one of my prefabs

[heady wyvern]

Can anyone assist me

so heres my issue

im creating a 3d game but using some 2D Sprites as char and monsters ect..

im following a guide and so i had everything all good

but now when i move "WASD"

i get these errors

and i added so when i click to attack it would target specific monsters

[old ibex]

Sorry to ask, but would you be able to get on a discord call so I could screen share my issue, I think you would be able to help me better if you could see exactly what I am saying. If you dont mind that is, you wouldnt have to talk.

[heady wyvern]

i get this when i click my target

[rich adder]

I'm at work I cannot

[old ibex]

Ok, thanks for helping

[rich adder]

I would suggest first debugging make sure the code is running there

put Debug.log inside your FadeOut method

[old ibex]

Ok I will try that out

[heady wyvern]

me ? @rich adder

lol

[polar acorn]

Something on that line is null but you're trying to use it anyway

[rich adder]

you have to show code for anyone to help

[polar acorn]

Find out what's null and make it not be that

[heady wyvern]

this is for clicking the target

[rich adder]

config your editor first

[polar acorn]

You never actually check if the raycast hits anything

Also, !ide

[eternal falcon]

You need to configure your IDE

So it shows errors and highlights syntax

[quick pollen]

Hey! Is this script okay for rotating towards an object on the y axis?

[rich adder]

the lerp is wrong

[quick pollen]

how can I fix it?

[rich adder]

also why are you making a quaternion like that

[quick pollen]

so its only on the y axis

[polar acorn]

what

[quick pollen]

if I rotate on other axises, this happens

[rich adder]

https://unity.huh.how/lerp/wrong-lerp

[polar acorn]

The axes of a Quaternion are not the same as the axes in 3D space

[rich adder]

I would go for the Coroutine option for lerp

[summer stump]

That wouldn't be how you do that
Basically never make your own quaternion

[tribal axle]

sorry for screenshot, but how do i acces this exact line of code in a different script?

[quick pollen]

well I know, so I tried to make up for that by using the slerped rotation in the 4th dimension

[quick pollen]

you need to serialize it or make an instance of it

most probably make an instance

[north scroll]

hey im having some issue here: Im trying to get the health var thats in the healthBar Script to match the bosses script health var, so im trying to get 2 files to access each other. This is how im trying to instantiate this and the Debug.Log prints out the Canvas name. This is how im trying to do the health reduction per hit on the oncollision (which has worked so far btw except without a UI),

if (other.gameObject.CompareTag("Bullet"))
{
    health--;
    healthScript.UpdateHealth(1);
    healthScript.currentHealth = health;

but i keep getting the error object reference not set on the UpdateHealth(1); line.

[lost anvil]

I have a door here that i want to play sounds when it starts moving and stop playing when it stops however im getting that reference error in the console and im not sure what to do.

[polar acorn]

The 4th value isn't just some magic number you need to provide to make the compiler happy and XYZ are unchanged. A quaternion fundamentally does not have anything to do with 3D space

[tribal axle]

but isnt making it an instance going to make it a different script?

[polar acorn]

The components are called x, y, z, w purely out of convention

[polar acorn]

Reference this object, then do .currentGameStage on it

        hinge.Rotate(-Vector3.up);
        return secondDistance - firstDistance;
    }
}

[quick pollen]

then how should I create rotation towards an object

[polar acorn]

Which line is throwing the error

[quick pollen]

tutorials tell you to use this hacky solution

like I looked into 4

and all 4 told me the same thing

to use this

I realized that the lerp approaches a value but never reaches it

[polar acorn]

If you want the object to rotate along a plane, instead of getting the direction to a target point, get a direction to that point but on this object's y position

[quick pollen]

but I never found a specific issue with that

[polar acorn]

Then you can just Slerp between them

[tribal axle]

like this?

[polar acorn]

No

https://unity.huh.how/references

[tribal axle]

how 😦

[polar acorn]

Reference the instance of whatever script this variable is on

[quick pollen]

and what if I make it so it rotates to an object but I put a constraint on it so it can only ever rotate on the y axis?

[polar acorn]

#💻┃code-beginner message

[polar acorn]

This is how you put constraints on it

[quick pollen]

I meant like a constraint monobehaviour

[polar acorn]

I don't know what you mean by this

[quick pollen]

theres a

[tribal axle]

i completely forgot about get component, thx lad, helped me out

[north scroll]

sry ive been working at this for like 30 min and 3 minutes after I asked I figured it out lol

[heady wyvern]

@rich adder

[north scroll]

the global healthScript was not the one being set to during start

[heady wyvern]

im on #3 i dont see add button

[summer stump]

That is not a 4th dimension. It affects the values of the previous three values

It is the colinear rotation magnitude of the xyz vector

[rich adder]

looking in the wrong place

[quick pollen]

oh right my bad

I knew that im just stupid

its for bypassing the gimbal lock

right?

[summer stump]

No

[quick pollen]

I thought thats why quaternions are used

[sage thunder]

I am trying to run a script on a mesh, but am getting the error that the mesh isReadable is false. It says to enable Read/Write on the import settings. I can do this, but then I have to redo a bunch of other stuff. Is there a way to enable Read/Write other than at import?

[quick pollen]

to fix gimbal lock issues

[summer stump]

It is a benefit of them, yes
But 1, that is not what the W component is for

[quick pollen]

ig its not for bypassing the gimbal lock it just helps with it while doing other stuff

while messing around with constructing that quaternion I did stumble upon some atrocities

[summer stump]

It's just a mathematical concept. You should not use it directly at all

[quick pollen]

and it usually was because of the w axis

[summer stump]

Again, w is not an axis. But I get what you mean

[quick pollen]

so ill get back to this, how can I do this?

[rich adder]

it says its Under Add Modules
but you already have VS you have to check if you have the workload

[quick pollen]

w parameter, sorry

[summer stump]

No worries. You got it, just wanted to make it clear

[quick pollen]

im just used to calling everything axis at this point

like its stupid how Vector3s already use xyz

even if you dont use it only for coordinates

tho tbf you do the same in maths soo

but when I think of a Vector I think of an Array kinda

i know its not the same but it heavily reminds me of it

I suppose I can try using MoveTowards

I just don't quite get how it works yet

[teal viper]

Must be having a C++ mindset...

[quick pollen]

yeahhh

in school we do c++

and it can mess me up so bad

also, if I set maxDistanceDelta to 0, does that mean that the object would rotate to target without moving?

[tulip hill]

i am completely new to unity, is transform written as a class? i see it like transform.rotate and im wondering if it has the same capabilities as a normal class

[quick pollen]

Transform is a field

its the situational values of something

i cant say position actually

more like coordinates and such

[tulip hill]

oh alr

[quick pollen]

where it is, how its rotated, what scale it has

wait

are we talking about Transform or transform

[heady wyvern]

is this right now

[summer stump]

Transform is a class, yes

@rich adder look good now?

im confused as hell

lol

[rich adder]

did you install the workload?

[quick pollen]

also @teal viper what if I use LookAt?

[teal viper]

No. This has nothing to do with movement or rotation at all. It just "moves" the value. Moves as in adds to or subtracts from.

[heady wyvern]

yeah i did for VS

when i first downloaded it

[rich adder]

then do the other part of the guide..

setup unity external tools, click regen project files there if you have set it already

[teal viper]

What about it?

[quick pollen]

it seems to work

[quick pollen]

ohhh

okay

I misunderstood it

[rich adder]

large code should be sent via code sharing links

[quick pollen]

its Vector3 not transform

[buoyant knot]

yes, but I can instance a Mathf

then I can instance a second Mathf

[static bay]

Yes sir of course sir.

[buoyant knot]

and then I can check if the first Mathf .Equals the second

and then put them in a big List<Mathf>

[teal viper]

Of course it does. It would be an outrage if such a core function wasn't working.😬

[static bay]

It's for backwards compatibility when they finally find the end of PI.

[quick pollen]

i meant that its doing what I wanted

but not quite

[buoyant knot]

And then define extension methods as
public static Mathf CombineMath(this Mathf first, Mathf second)

[quick pollen]

ill try using movetowards

[teal viper]

Well, that I don't know. Share the new code.

[buoyant knot]

then at some point, I can make a List<Tuple<Mathf, float>>, so i can effectively store a list of floats, with the relevant Mathf instance I should use for it

i can make the most cursed code ever

I wanted something like this

but idk how to turn transform.rotation into a vector3

[teal viper]

Why vector in the first place? Rotation is a Quarternion.

[rocky canyon]

it is a vector

ohh euler

[quick pollen]

you said I should use MoveTowards

MoveTowards is a vector3

[rocky canyon]

Euler angles is what ur wanting i think

[teal viper]

MoveTowards is not a vector3

i thought of it but it doesnt work

i meant this

It's a method in Vector3. But there is a similar method in quaternion too

Check the docs.

[quick pollen]

ah

theres Quaternion.LookRotation

which I know of

[teal viper]

Not that

[quick pollen]

then?

[teal viper]

Read through the available methods

[quick pollen]

FromToRotation?

[teal viper]

Specifically the static ones

No

[quick pollen]

I was thinking slerp but thats not it either

RotateTowards?

[teal viper]

Yes

[quick pollen]

but that doesnt have-

oh it does

wtf

[tulip hill]

how do i detect inputs on unity code

[quick pollen]

you gotta use an inputsystem

[tulip hill]

idk

[quick pollen]

vector3 is not a quaternion

public class RotateToPlayer : MonoBehaviour
{
    public Transform target;
    public float RotationSpeed;
    private Vector3 _direction;
    void Update()
    {
        _direction = (target.position - transform.position).normalized;

[soft steppe]

Hi, so currently im following brackey's first Person Movement tutorial and i hit a problem when trying to implement camera rotation on the x axis it simply blocks rotation on y axis ( the problem may be due to me using the Input System and the tutorial using the legacy input system but i am not sure )
here is the code im using:

public void look(InputAction.CallbackContext context)
{
    if (CanMoveCamera)
    {
        xRot -= context.ReadValue<Vector2>().y * mouseSensitivity * Time.deltaTime;

        xRot = Mathf.Clamp(xRot, -90f, 90f);

        transform.localRotation = Quaternion.Euler(xRot, 0f, 0f);


        transform.Rotate(Vector3.up * context.ReadValue<Vector2>().x * mouseSensitivity * Time.deltaTime);
    }
}

note: context.ReadValue<Vector2>() returns current pointer delta movement.

[quick pollen]

the problem is _direction

I need to turn it into a rotation/quaternion

Quaternion.Euler maybe?

[tulip hill]

is mouse1 lmb?

[rich adder]

no

also take beginner course instead of guessing

[tulip hill]

im looking at a tutorial

also it doesnt let me take the new to unity thing

[summer stump]

Mouse1 is rmb

[tulip hill]

i dont see it anywhere

[summer stump]

What is that?

[quartz grove]

Guys did everything here but still ide doesn't work

[tulip hill]

is it bc of the 0, 1, 2 index notation on c#?

[tulip hill]

apparently unity has a free built in course

[summer stump]

In programming yes

[quick pollen]

still doesnt work

idk how to

you did not follow the guide

[summer stump]

Shouldn't say internal

[rich adder]

also I dont have time for this rn sorry

[quartz grove]

How

[quartz grove]

: )

[summer stump]

You find the program and set it to it
As it says in the guide

[teal viper]

Look at the quaternion docs again. There's a method to create a quaternion from a direction.

[quick pollen]

isnt it Quaternion.Euler?

[rich adder]

if its showing Internal A. you did not remove the VSCode editor package and B. did not update Visual Studio Editor package

[teal viper]

No. That's from an angle not a direction@quick pollen

stopspamming the fucking commad and scroll up..

[rocky canyon]

its a quaternion, and it uses a direction.

will it work for ur use-case?

[teal viper]

Yes

[quick pollen]

except FromToRotation says this Usually you use this to rotate a transform so that one of its axes eg. the y-axis - follows a target direction toDirection in world space.

is Visual Studio Editor what i needed? for !ide

And yes

[teal viper]

What's the problem with it?

[rich adder]

jesus christ people today

[summer stump]

Remove the Visual Studio Code Editor package

[quartz grove]

STOP BEING MAD EMO

[summer stump]

Don't

[rich adder]

why dont you learn how to keep a web page open instead of being a forgetful ant
there is no need to spam the command when you can just scroll up and keep link open..

[quick pollen]

I thought its meant to be the one

[heady wyvern]

you just said thats what i needed for i.d.e so i delete it tho?

[summer stump]

No, you need the Visual Studio package. Remove the Visual Studio CODE package though

Ah, Yeah I miswrote it earlier. Sorry

[quick pollen]

now I need to find a way to lock the rotation to the y axis

[heady wyvern]

so im set with i.d.e?

after i delete that code one

[summer stump]

How should I know? That is one step
There are others

[heady wyvern]

lol

[quick pollen]

maybe I can create a new direction which is just _direction without the x and z?

[heady wyvern]

this guide is poop tbh

or im just stupid

[quick pollen]

how do you know if ur not even following it properly lmao

[summer stump]

It's like a couple steps. It's dead simple

What have you done so far?

[rich adder]

bruh you struggle with this, making a game aint gonna be easier

[teal viper]

Yep. I think you were given that solution by someone some 30 min ago.

[quick pollen]

yeah it was digiholic

[heady wyvern]

rome wasnt built in a day

😞

[quick pollen]

somethings still messed up

its rotated wrong

like its facing the ground

not me

[quartz grove]

So do not try to offer educational courses or help others if you are quick to anger and disrespectful to beginners

[teal viper]

Share code

[summer stump]

Why are you doing this? Stop

[rich adder]

I expect some level of comprehension

[quick pollen]

public class RotateToPlayer : MonoBehaviour
{
    public Transform target;
    public float RotationSpeed;
    private Vector3 _direction;
    private Quaternion _rotation;
    void Update()
    {
        _direction = (target.position - transform.position).normalized;
        _rotation = Quaternion.LookRotation(new Vector3(0f, _direction.y, 0f));
        transform.rotation = Quaternion.RotateTowards(transform.rotation, _rotation, RotationSpeed);
    }
}```

actually

do I need to do the exact opposite

have x and z but not y

[quartz grove]

"stopspamming the fucking commad and scroll up.." your friend said that bec i wrote a code

[summer stump]

A bunch of times. Yeah.
But still, stop
It's over

[rich adder]

you keep spamming bot command instead of keeping a link open?

anyway i have no time to bicker with you

goodluck to ya

reading a step by step guide with screenshots isnt exactly coding or some sort of special science

[quick pollen]

it works!

yeah I was stupid

I meant to freeze the Y rotation

[rocky canyon]

get ur axis' straight! 😛

[quick pollen]

not unlock the Y rotation

[quartz grove]

Don't expect me to be respectful to anyone who disrespects me
I am here to learn
If you are a very angry person
He curses in his words

So don't talk to others and go develop your own game

[summer stump]

Just learning, you're all good!

[quick pollen]

fr lol I always fuck up these things

[rocky canyon]

it gets ezier

[quick pollen]

like I just cant remember what axis is what

especially x and z

[summer stump]

You are spamming, and disrespecting the whole community. Stop

[quick pollen]

I know z is the forward axis

the blue

green is y

and red is x

[heady wyvern]

@summer stump i followed all the steps how do i know if i got .i.d.e to go correctly

[quartz grove]

Talk with your friend sir

[quick pollen]

but I mess it up so often when I have to rotate around them

[summer stump]

Which steps have you done?
If you misspell something it should give you a red underline

Maybe show a screenshot of the ide

[summer stump]

<@&502884371011731486>

[teal viper]

Whatever that thing in Look rotation, it doesn't look correct

[quick pollen]

tysm @teal viper @rocky canyon @summer stump and whoever else who helped :)

[quartz grove]

<@&502884371011731486>

[quick pollen]

yes I meant to freeze the y rotation and unfreeze the others but instead I unfreezed the y rotation and freezed everything else

using UnityEngine;

public class RotateToPlayer : MonoBehaviour
{
    public Transform target;
    public float RotationSpeed;
    private Vector3 _direction;
    private Quaternion _rotation;
    void Update()
    {
        _direction = (target.position - transform.position).normalized;
        _rotation = Quaternion.LookRotation(new Vector3(_direction.x, 0f, _direction.z));
        transform.rotation = Quaternion.RotateTowards(transform.rotation, _rotation, RotationSpeed);
    }
}

final thing

and thank u @teal viper especially for giving me hints and not an exact solution

did take more time but at least I'll (hopefully) make shitty mistakes like this less often

its like 3 am

its especially hard to think right rn

[north kiln]

@quartz grove Stop yabbering. If someone tells you to stop spamming the command, respond nicely instead of arguing. It's not hard to scroll up or reopen a webpage, and that's all that's being asked of you.

[quartz grove]

Why do I respond politely to someone who asked me something in an impolite way?

I see that there is bias in the administration

[quick pollen]

"final product"

(i suck at animations pls ignore)

[north kiln]

@rich adder don't swear at people when you want them to stop. You can keep things polite too.

[rich adder]

You're right . My Apologies

[shell sorrel]

because are trying to instigate things, it looks like the kid "yelling i am not touching you" with there hands up in someone's face

[quartz grove]

Good my apologies as well

[quick pollen]

because we should at least try to pretend to be mature adults lol

[summer stump]

No, it's unfortunately not configured

[quartz grove]

O'Brother
Believe me, I was very hurt because I tried to ignore bad manners

[quick pollen]

(i say that but im immature anyway lol)

[summer stump]

Try clicking "regenerate project files" in external tools

[quick pollen]

not saying you should ignore them forever

but especially when ur receiving help

and people are spending their time on u

[quartz grove]

anyways good luck

[quick pollen]

if someone is being impolite with you irl for no reason

then yes

[quartz grove]

Believe me, I don't need help from anyone who doesn't know how to talk

The topic is over now, let's not reopen it

[quick pollen]

you have the "right" to be impolite in return, but its better to walk away

[quick pollen]

sure, just keep an eye out for things like these

[robust moss]

hey y'all

[quick pollen]

hi

[robust moss]

currently working on a couple projects for various beginner level understanding, and I'm wondering if there's any websites for learning unity.
I've already found docs.unity.com and learn.unity.com, but I'm curious about other websites, just to know the different options

[summer stump]

There are pins in this channel

[robust moss]

sweet, thanks

[oak mist]

Code: https://pastebin.com/EeP4H6Xy, I have a question on positioning. Basically ive almost solved my issue and im almost done. I have a turret which operates on a spaceship, and only moves left and right (well rotates left and right), and it took me a while but i got it running. Which is fine when the ship is moving forward and backwards, or left and right, but for up and down, the ship stays at its rotation and doesnt rotate up, so it glitches into the cockpit and looks a little odd. Any workaround for this?

once this is done i can call it a day and finally rest easy.

[wintry quarry]

You should be using localRotation/localEulerAngles and convert any world space positions to local positions

That will easily let you enforce limitations on the object's rotation relative to the parent (the ship)

[oak mist]

beautiful

hold on let me try

[wintry quarry]

It will take some fiddling

[oak mist]

so would i have to also change the Move towards angle also

[wintry quarry]

I mean yeah just do everything in local space

Also recommend maintaining your own variable for the rotation rather than reading the euler angles from the transform

[oak mist]

perfect

its done

finally

i can sleep

thank you so much ur a lifesaver

[heady wyvern]

If anyone can help i cant get i.d.e because im not sure if i need to buy VS or what but some options are missing. anyways in my game i use WASD to move and when i move i get these errors

thats the code on the right it pulls me to when i double click the errors

[rich adder]

did you regen project files like Aethenosity said

[heady wyvern]

wheres that option at i couldnt find it

[rich adder]

Edit -> Preferences -> External Tools

[summer stump]

You do not need to buy anything

[summer stump]

Your error is because the attackRoutine isn't set to anything when you call StopCoroutine

[ashen trail]

IDE setup is not working for me

[summer stump]

What have you done so far?

[summer stump]

Also, ALL these IDE questions should be in #💻┃unity-talk

[ashen trail]

mb

[heady wyvern]

@summer stump @rich adder sorry for asking so much this is very new to me so again sorry lol

[summer stump]

No worries, it's fine!

[rich adder]

double check https://unity.huh.how/ide-configuration/visual-studio-code these steps

seems you dont have the SDK but only runtimes

[rich adder]

*thread prob

[rich adder]

did you do the step ?

[summer stump]

Yeah, I'm never sure honestly. It's good in this channel? I guess it IS usually where it is asked

[rich adder]

not sure tbh lol but I think so since it kinda code topics

[heady wyvern]

is that in unity or VS

[rich adder]

In Unity, did you not follow the steps in the guide its part of it.

well there is your answer

Visual Studio isnt even selected!

[summer stump]

It would have been the step in the guide where you set the tool used by unity

[rich adder]

^ make sure you regen after that

[heady wyvern]

swear i had it switched lol but ig not but

regen

ok

do i select any other boxes on that?

or good to go

[rich adder]

should be fine

[rocky canyon]

double click one of ur scripts

ull find out

[rich adder]

make sure u close vs though when u regen

[rocky canyon]

you'll see Assembly-CSharp when its good

[rocky canyon]

aye 🎉

your life is now atleast 3x better

[heady wyvern]

lol

ok so i see

1 asset referenced 0 refferences

[shell sorrel]

means 0 references in code

1 asset with the component on it

[rich adder]

yes You are not referencing this script anywhere

[rocky canyon]

peek-a-boo

[rich adder]

^^ these are runtime errors and do not show up in IDE @heady wyvern

btw Update is a Unity callback so it gets autocalled so no References there

[shell sorrel]

yeah the ide will tell you about compile errors

NRE is runtime error, not knowen till that code that casues it executes

assuming player is null, and not assinged in the inspector

but the error in the console will have a stack trace to show you where

[heady wyvern]

so as in a "Refrencing" the script thats like adding a component - script onto a object?

like my "Target"

or referencing it in the script itself

[rocky canyon]

if you say public GameManager myGameManager; and put that script onto an object

u have to fill in the newly made slot for a GameManager

if u go to run that script and its not referenced.. theres ur error

[summer stump]

No, that would not be a reference
You have to "point" to that component. Not just add it

[rocky canyon]

https://user-images.githubusercontent.com/60554748/227689794-0f5b9380-7db1-4a99-91c5-0644e45e8cf3.gif

^ this would be a reference to Apple.cs

[summer stump]

And the thing you do in the script itself is declare a variable, then you reference it, either with the = sign, or like spawn camp is showing

[rich adder]

Think of referencing like bookmarking a page in a book

You know which book and which page you want to find specific info

[rocky canyon]

think of it like a pointer..

[summer stump]

public GameManager gameManager

^ this is a declaration, NOT a reference until you actually fill the variable with something.
It is "null" by default

[rocky canyon]

to which specific Instance of that class ur trying to reference

[rich adder]

also valid 😛 i tried a simpler more relatable analogy

[rocky canyon]

he may have figured it out by now 😅

[summer stump]

https://unity.huh.how/references

This shows multiple methods to reference things. Serialized References is what SpawnCamp was showing

[rocky canyon]

oh bam, there u go ^

[rocky canyon]

two of the same 😄

[summer stump]

Sorry for the overload haha.
Let us know if that was too much

[rocky canyon]

he's already building the menu by now

[summer stump]

Probably already looking for publishers

[rich adder]

game already has 20k steam wishlisting

[rocky canyon]

i got whats the coders version of writers block? or it could be just procrastination

not sure where to go on my project

[heady wyvern]

lmfao

[rich adder]

i usually try to learn something new and give the mind a break from the same thing
eg if you're constantly working on gameplay features, work on the menus? music? the artwork ? or maybe some unrelated (kinda)

[shell sorrel]

its just procrastination

yeah there is always something to do, but games covers alot of domains so its easy to change things up

[heady wyvern]

so wouldnt this be like your apple GIF @rocky canyon

[shell sorrel]

or easy to working on something a little more mindless if your head is not in it

[rocky canyon]

yup, ur private Player.. is visible in the inspector b/c of the [SerializedField] attribute u used..

[summer stump]

You have successfully referenced an instance of the player script

[rocky canyon]

so in that case you pull in the gameobject that has the Player script on it

[rich adder]

step 1/2
step 2# make sure its assigned

[rocky canyon]

and when u run any code referencing that player.. it'll know which gameobject has that player script

👍

i have lots more faith in you than some i see around here 🙂

[summer stump]

It's a wiiiide screen. It's assigned on the right

[rich adder]

ahh wops looked on it from phone lol

[rocky canyon]

yea, it looks good.. no console errors.. it has a reference.. the player script has a MyTarget variable..

[shell sorrel]

yeah its assigned, though in the code i would null check the collider on the hit, to make sure you got a hit

[rich adder]

btw you I think you could get a null ref if hit.collider is null since you're accessing a tag on collider

[rocky canyon]

if that variable is public (can be accessed in ur GameManager script) ur solid

[heady wyvern]

like Debug.Log?

[rich adder]

Debug.Log just prints the result

[summer stump]

if x == null

[heady wyvern]

i deleted the .tag on the end of that one and that error went away when i clicked the "Target" now

[heady wyvern]

ok

[rich adder]

because thats the proper way to check the collider is null first

[rich adder]

no not like this lol

.tag is trying to access collider and if no collider is found, it will throw NRE anyway. You cannot run .tag on a null object

[summer stump]

You wanna check hit.collider
Not hit.collider.tag

[rich adder]

and for tag checking you should use collider.CompareTag instead of == btw

https://docs.unity3d.com/ScriptReference/Component.CompareTag.html

[rocky canyon]

..and wrap ur raycast in an if statement and then u wont have to worry about null tags when theres no hit variable

[rich adder]

is there a bool version return version?

for 2D

[rocky canyon]

ohh

[rich adder]

don't think 2D has it

[rocky canyon]

i meant like this.. but ur right.. i know nothing about 2d raycasts

thats odd that u cant

[rich adder]

https://docs.unity3d.com/ScriptReference/Physics2D.Raycast.html
Yeah I dont see it here

[rocky canyon]

weird.. why not i wonder.. im sure its been ticketed/requested

or maybe im tripping

[heady wyvern]

im creating 3D

[rich adder]

then why are you using a physics2D function

[heady wyvern]

i put 3d and it doesnt work lol

[rich adder]

wdym doesn't work

are the colliders 3D or 2D?

[heady wyvern]

i tried both 3d and 2d

[summer stump]

You only write 2d for things. You just don't write either for 3d

[rich adder]

stuck t one thing...

[summer stump]

So Physics or Physics2D

[rich adder]

and dont randomly change stuff without knowing why

[summer stump]

Collider or Collider2D

[heady wyvern]

i mean colliders

[leaden dove]

anyone good at c# sharp?

[summer stump]

Yes

https://dontasktoask.com/

[heady wyvern]

i tried both regular collider and 2d

[leaden dove]

im making a game with some people we need coders lol

hi, how do you rotate a gameobject to face towards a cube's corner?
(the screenshot shows an invisible capsule outlined in green, which i am trying to rotate to face the corner)
i have script attempting this, but i just want to know how to do it in general:

using System.Collections.Generic;
using UnityEngine;

public class raycastMove : MonoBehaviour
{
    public GameObject bigCube;
    public GameObject playerCapsule;

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
            //draw ray in playercapsule's forward direction
            Debug.DrawRay(playerCapsule.transform.position, transform.forward, Color.white);


            //draw ray that collides with the cube's corner
            Debug.DrawRay(bigCube.transform.position - (transform.forward - transform.right).normalized, 
                          (transform.forward - transform.right).normalized, 
                          Color.blue);


            RaycastHit outCornerAngleHit;
            if (Physics.Raycast(bigCube.transform.position - (transform.forward - transform.right).normalized, 
                                (transform.forward - transform.right).normalized, 
                                out outCornerAngleHit, 
                                30f))
            {
                //Move playercapsule to cube's corner
                playerCapsule.transform.position = outCornerAngleHit.point;
                //Rotate playercapsule towards where cube's corner was hit
                playerCapsule.transform.rotation = Quaternion.RotateTowards(playerCapsule.transform.rotation, Quaternion.LookRotation(-outCornerAngleHit.normal), 3600);
            }
    }
}```

[rich adder]

that makes lot of sense, I was gonna say why wouldn't they have a bool option 😂

TIL

[leaden dove]

plz shup up :I

[rich adder]

oh wellOP is using 3D colliders anyway

[rich adder]

don't be toxic

It is a common thing to link here. It has helpful information
