it pings the object in the hierarchy

[edgy fox]

I clicked on it and it didn't do anything

[rocky canyon]

wow, i just learned of this physics debugger, as well as the frame debugger, these tools are awesome

[edgy fox]

ik same

but where in the log do I click to highlight

[rocky canyon]

its subtle.. when u click once it highlights it in a yellow box

if u double click it it will automatically select it

[edgy fox]

it doesnt highlight it htough

wait im dumb

waiit no it doesnt

it works if I do a different gameObject but if I do Debug.Log("Click", hit.transform.gameObject) nothing happens

but if I just do Debug.Log("Click", gameObject) it highlights an object

but I only have 1 object named WallEZ so I know which one it is

[native seal]

anyone know how to fix The referenced script (Unknown) on this Behaviour is missing!

[wintry quarry]

Remove it and add a valid script

[native seal]

well idk what its on lol

its just popping up 4 times

[queen adder]

cursed

[wintry quarry]

Unfortunately it doesn't tell you which object. I think there's a few scripts floating around that will track it down

[native seal]

any suggestions?

[rich adder]

are you sure its not the ones from saving/compiling scripts while in play mode?

[wraith mango]

why would it take in the transform to assign the new object a parent

sorry if that was worded badly

this is for instantiating, should've been more specific

[timber tide]

well, if you want to parent it on the hierarchy then you're free to do that, otherwise it'll just be in world space

[wraith mango]

i need it to instantiate as a child of another object

[abstract pelican]

Can you tell me why this doesn't work in the isometric world?

if I press W then it goes to the left

[timber tide]

well, then you give it the parent of the object you want to child it with

[wraith mango]

why is it a transform, and not a gameobject

[timber tide]

all gameobjects have a transform (if they exist in the scene, then they must have some type of coordinates in it)

it's just a unity thing

[wraith mango]

alr i just didn't think it made sense lol, i figured it would take a gameobject

[abstract pelican]

help guys

[timber tide]

you're right in a sense that it would make more sense to be a gameobject ref, but if you think about it more it is about placement in space (vector/rotation/matrix via local coordinates) which is more related to transform values

[wraith mango]

what ide is this?

[wraith mango]

alright thank you 😊

[abstract pelican]

Rider

[wraith mango]

jeez

expensive

[abstract pelican]

I use it for free

who will help me with my problem?

[wraith mango]

your assigning the currentrunmovement.z to y

i could be wrong im just guessing

[abstract pelican]

and which one is needed?

I have a top-down camera, the character moves normally

but there is no isometry

[wraith mango]

im confused

you said your character is moving the wrong way

[abstract pelican]

Yes, that's right, he doesn't walk correctly in isometry

if I press W it goes to the left, if I press A it goes down

it turns out 90-degree turns, instead of 45

In theory, if I press W it should be 45 degrees

But instead I turn 90

[tough lagoon]

It doesn't look like you are coding it to go 45degrees. You are using a lookat and rotating that way

[abstract pelican]

how do I fix it in my code?

[tough lagoon]

transform.Rotate(new Vector3(45,0,0);

As for movement, you are using WASD as arrow keys. And applying the position of the arrow keys. Most isometric aren't left to right and up and down though. A tile based isometric you usually want left x2 and up x1 for example.

But you have the code on going left / right/ up / down. It's just a guess though as the input keys are using the newer input manager and would need to be verified there as well

Basically you need to take the input and adjust it for the view of your game

[abstract pelican]

like this?

[tough lagoon]

No, why are you adding a lookat?

If you want to rotate it 45 degrees, just do transform.Rotate(new Vector3(45,0,0));

Like, you can just rotate it 45 degrees without needing to add anything else

I'm not sure why it is doing a lookat etc.

But maybe it's needed? It would depend on the context of the rest of the project

[rocky canyon]

Why are my Debug.Log()s are so different? The left image is 2021.3, and the right image is 2022.3
I haven't changed any settings that I know of. The only difference is the first is a Windows project, and the other is a Mobile project.
Same code, same debug yet :

• The 2021 Windows version is cleaner and I can double-click it to show the line in VSCommunity.
• The 2022 Mobile version is cluttered (having the line number way down the stack. and a double-click does not open VSCommunity

[abstract pelican]

Well, how do I move around in an isometric world?

[soft canyon]

I'm making a custom editor for one of my scripts right now but the object assign box is super small when there is plenty of space between the label and box

This is my current code:

        dungeonGen2.distObject1 = (GameObject)EditorGUILayout.ObjectField("Object 1", dungeonGen2.distObject1, typeof(GameObject), true);
        dungeonGen2.distObject2 = (GameObject)EditorGUILayout.ObjectField("Object 2", dungeonGen2.distObject2, typeof(GameObject), true);
        EditorGUILayout.EndHorizontal();```

And ChatGPT is telling me to split each one into two lines to set the label size like this:
```EditorGUILayout.BeginHorizontal();
EditorGUILayout.LabelField("Object 2", GUILayout.Width(70));
dungeonGen2.distObject2 = EditorGUILayout.ObjectField(dungeonGen2.distObject2, typeof(GameObject), true) as GameObject;
EditorGUILayout.EndHorizontal();```

Is there a way to set the size of the label and keep it all in one line per object-label pair? I tried just putting the GUILayout.Width(70) after "Object 1" and it didnt work

[abstract pelican]

If I do as you suggest

[tough lagoon]

I'm not sure on the specifics, but the right one has a bigger preview pane below it (you can click and drag that middle line to increase the size)

[rocky canyon]

im aware.. but thats all it is on this version

[tough lagoon]

I don't think I can be more specific over discord on my phone, sorry!

[rocky canyon]

lol the mobile setup* just has SOOOO much stacktrace lol

[tough lagoon]

Is that in the editor view or while testing on device?

[rocky canyon]

its the editor..

[tough lagoon]

What version is that one?

[rocky canyon]

im just trying to figure out what the difference is exactly.. b/c the Big one.. doesn't open Visual Studio when i double click it.

like the smaller version does

the big one

and the small one

just strange.. unless the mobile setup uses different types of logs?

[tough lagoon]

Im not sure why the one on the right is showing a detailed stack trace. But it's not narrowing it down to code. I'm suspecting there is a debug option enabled somewhere for stack trace digging

[rocky canyon]

thats the only thing i can think of as i didnt really change anything besides from 1 line to 2 line

[rocky canyon]

ill try to compare the two and see if theres just a tickbox im missing

[north kiln]

You have stack traces set to full

Go through the top right menu of the console window, or the player settings and set them to Script

[rocky canyon]

ur a life-saver

❤️ so much better

And the double click to open in VS works again!

not sure how that got flipped lol, TIL📝

[north kiln]

The setting for the window is annoyingly the same as for builds

[rocky canyon]

i didn't mind at first, until I started looking for line numbers.. had to scroll half a page to find the first script hyperlink looking thing

[abstract pelican]

How good is this solution?

[north kiln]

Why am I being pinged?

[abstract pelican]

so that the control is normal in 3d isometry

[north kiln]

what on earth does this have to do with me

[abstract pelican]

We've been talking to you, haven't we?

I can't see well, I have a disability, don't you get mad 😭

[rocky canyon]

my two cents: if it works, roll with it. If there's an issue with it you'll discover it before too long,
and if it needs optimized in the future, that's a future project..

• does it work ?
• can you understand it ?

[abstract pelican]

it works, but I don't understand how it will affect memory

[rocky canyon]

it cant be worse than polling for input.. which is what usually gets done

[abstract pelican]

well, thank you

[rocky canyon]

open up the profiler, and check

[abstract pelican]

I don't understand what to use instead in the new version

[abstract pelican]

I don't know how to work with him yet.

[wintry quarry]

It literally says what to use instead

[rocky canyon]

ahhh i miss rider 😦

no suggestions for me 😢

[north kiln]

if your Unity version has it as obsolete it should mention obsolete methods no matter the IDE, no?

[abstract pelican]

download a rider for yourself

[rocky canyon]

not sure

[north kiln]

Also, Rider EAP just started, you can use it for free for a bit again

https://www.jetbrains.com/rider/nextversion/

[rocky canyon]

brb! lol

[abstract pelican]

yes

I use it for free

[north kiln]

the EAP just started yesterday

[wraith mango]

code: https://hastebin.com/share/ikibexemim.csharp

The problem is that there shouldn't be that space between "objectives" and "obtain one coin", then when i run the complete function it tries to replace the white space instead of obtain one coin

[abstract pelican]

I've been using it for half a year now

[north kiln]

it says you have a subscription

[rocky canyon]

visual studio is ole' reliable.. always there when you need it most..
but rider, ❤️ me some rider.. like that new toy you don't need but looks great cruising around town in 😄

[abstract pelican]

I didn't even come in.

I activated the code that was sent to my email

I shared it with a friend, and he uses it too

[north kiln]

You got the license somehow—presumably by paying for it

[rocky canyon]

well, thats fortunate

student perks perhaps

[north kiln]

Maybe

[abstract pelican]

I can't physically buy it, my banks don't work.

[north kiln]

Are you using the github student developer pack then?

[abstract pelican]

no

[rocky canyon]

🏴‍☠️

[abstract pelican]

no

[rocky canyon]

lol jk with ya 😄

[abstract pelican]

I just downloaded it from the website and wrote to them

I get all the updates that come out without any nonsense

[north kiln]

and wrote to them?

[rocky canyon]

well, lucky you

yea, i need to email em too.. see if i can get a hook up with free liscense

[abstract pelican]

I was told that I can use it until the release of the 2024 version

after that, she will turn off

[north kiln]

Right, well I have no idea why you buried the lede

[rich adder]

iirc its free if you contribuite to open source repos

[north kiln]

You can see all the discounts https://www.jetbrains.com/rider/buy/#discounts

[abstract pelican]

can you tell me a good plugin to put the code in order?

[rich adder]

@rocky canyon this what I meant 🙂

[edgy fox]

so the conversation earlier just sort of ended... when I click on the debug message for Debug.Log("Click", hit.transform.gameObject); nothing gets highlighted

[abstract pelican]

so that he formats my code beautifully

[north kiln]

The only cases that can happen as far as I know is if the object was destroyed or isn't in the scene or hierarchy for some other reason

[wraith mango]

the student one specifies "university email address" - but there is a checkbox for high school, is there like something im missing

[edgy fox]

no objects are destroyed

[north kiln]

No idea, if you're a student you can just go through this to get loads of stuff https://education.github.com/pack

[north kiln]

Can you send the entire script !code

FindNeighbors is where the issues are

[wraith mango]

code: https://hastebin.com/share/ikibexemim.csharp

The problem is that there shouldn't be that space between "objectives" and "obtain one coin", then when i run the complete function it tries to replace the white space instead of obtain one coin

[abstract pelican]

I can give you the key and you can try

I do not know how many times it can be used

[wraith mango]

would be greatly appreciated

[abstract pelican]

write to me in private messages

[north kiln]

I can't see what the issue would be. Perhaps try to Debug.Break() when the issue occurs so it pauses, and then you can see the state of the scene at that point.
What is the name of the object it looks like it's hitting (when selected via the physics debugger overlay?) at that point in time...
Perhaps use the debugger instead of the logs to see if you can gleam any more info, like the hierarchy or something else

[edgy fox]

how do you view what is being hit via physics debugger?

[north kiln]

Just by looking visually and using the Mouse Select option in the bottom right menu, selecting the object

[edgy fox]

there is no object there to select

its still just hitting nothing

[north kiln]

these screenshots are showing objects there though?

[edgy fox]

those objects are ignored via layermasking

[north kiln]

stop thinking about that for now

they are still things you should consider

[edgy fox]

its hitting BlankSouth

but logs say WallEZ

[abstract pelican]

can you tell me how to make steps for a character so that there is not a lot of sound of steps?

[north kiln]

what's this object?

[edgy fox]

that's the wall that has arrows here

if WallEZ there doesn't exist, this bug doesnt happen and it doesnt register as hitting anything

[north kiln]

and this one?

[edgy fox]

that;s the plane floating in tthe distance

top left of screen

[north kiln]

Can you disable the blank wall that it looks like it's hitting, and then advance the frame and look again?

[edgy fox]

right now, the bug happens if the cloned wallEZ exists there and doesn't if it isn't there

[north kiln]

Does the cloned wall get moved around at all?

[edgy fox]

like redo it with the blank wall disabled or disable and continue?

the cloned wall does not get moved after instantiation

[north kiln]

No, just checking if there's something there when you disable the one it's apparently hitting

[edgy fox]

yeah the code instantiates it prerotated and premoved

if (Physics.Raycast(hit.transform.position, hit.transform.rotation * new Vector3(0, -1f, 0f), out RaycastHit hitInfo, 0.5f, wallMask))
{
    Instantiate(newWall, hitInfo.transform.position, Quaternion.Euler(new Vector3(0, hitInfo.transform.eulerAngles.y, 0)), hitInfo.transform);
}```

that's the code that puts it there

with newWall being WallEZ

[north kiln]

Do any of the parents of WallEZ have a rigidbody?

[edgy fox]

there are no rigidbodies anywhere in the scene

[north kiln]

if this works it's probably not the solution you should go with, but it might fix it... can you add Physics.SyncTransforms before FindNeighbors?

[edgy fox]

still doesnt work

[north kiln]

I have no idea at this point. I think you'll have to upload your project somewhere to have someone else look at it unless someone else has an idea

[edgy fox]

dang thanks for trying

I'm completely stumped

[spring skiff]

can someone tell me what is wrong with this?

    private bool[] myArraybool = new bool[30];

I want to set a max. length directly in the script because I want to keep my Inspector clean.

[gaunt ice]

then recreate a new array and copy all stuff into it

or using some wrapper of an array ie list

[spring skiff]

What do you mean?
Atleast my code can not be right if Unity say IndexOutOfRange.

But what do I have to write to limit my bool array to "30"?
I can't find anything in google because all peoples use a public array and give their lenght value in the inspector.

[gaunt ice]

you already limit the length by setting the length

[spring skiff]

is my code not wrong?

    private bool[] MyBool = new bool[1];



    void Start()
    {
        print("MyBool 0 = " + MyBool[0]);
        print("MyBool 1 = " + MyBool[1]);
    }

[gaunt ice]

ofc you cant access the memory space with index >= array.length

[spring skiff]

what do you mean?

the last print is to make sure thaat it should not work.
but even if I outcomment it I still have this error.

its always confusing me when '0' does count and when not.

If I say bool[1], does this not mean the "0" is also counted?

[gaunt ice]

array index starts from 0

[spring skiff]

so whats wrong with the code up there?

[gaunt ice]

this

[spring skiff]

IDK what " index >= array.length" means

[gaunt ice]

your array length is 1 and you try to access [1]

[spring skiff]

Ok now it becomes day.
Its just so weird I thought all the time:

private bool[] MyBool = new bool[1];

mean a value of 2 bools because the '0' does matter in this private bool.

[gaunt ice]

and basic counting, for open interval [0,b) ie 0<=index<b the count is b-0 while for closed interval [0,b] ie 0<=idx<=b count is b-0+1
hence the valid range of index is [0,b)

[spring skiff]

ok thx.

[gilded pumice]

Hey all so I'm trying to get a chest to spawn random loot when opened. I have the following code to do this:

if (collision.gameObject.CompareTag("unlockbronze") && playerAttributes.bronzeKeysRemaining > 0)
{
playerAttributes.RemoveBronzeKey(1);
Instantiate(chestLootPrefabs[chestLootPrefabsIndex], collision.transform.position, collision.transform.rotation);
StartCoroutine(OpenChestDelay(collision.gameObject));

}

this does not throw an error, but it doesn't instantiate the loot either. If I remove the "collision" from the transform position and rotation, it works and instantiates the object on the player, which is obviously not what I want to have happen. I tried making a script and attaching it to the chest directly but it doesn't trigger since the chest is static (plus I'd prefer not to do it that way if I can help it). Any thoughts or help?

[north kiln]

So have you confirmed that the code is running?

[gilded pumice]

I didn't debug it, but the other parts of the code function as intended (the bronze key is deducted from inventory and the chest is destroyed after a delay)

so the code block is at least executing

[north kiln]

Because if it is, then it is instantiating the object. Perhaps just not where you think it is?

[gilded pumice]

well, nothing new appears in the hierarchy. I guess I'm wondering if the collision.transform.position is correct syntax, or if its doing something else (this was a complete guess on my part to try to change the spawn point from the player to the object the player collided with)

[dim halo]

hello guys

I want to download unity editor 2019

where can I download it from?

[gilded pumice]

figured it out. just had the tags set to the wrong chest type. Thanks for the response!

I don't have dc on my laptop

I'ma install it rq

[timber tide]

https://docs.unity3d.com/ScriptReference/Quaternion.LookRotation.html
So in this example they don't normalize the direction placed into this method, nor normalize the quaternion afterwards. It says it does set it to a normalized forward direction afterwards is why I ask.

testing there doesn't seem to be a difference but with rotations like to lie to me

[north kiln]

I believe they normalize it, however that's not gonna be guaranteed if you use any other library

Quaternions from Unity methods are always normalized however

they are never going to be broken

[fringe plover]

does someone know how to make dropdown like here in my own script?

The easiest thing would be to use an enum

Here's the code im using for rotating the steering wheel in my car, i want it to rotate back to original position when i dont turn the vehicle though, any approaches i can take?

[tawdry dome]

Why when I click create a new palette and create a folder, nothing happens and I can't create a tile palette?
This is on 2D btw

[buoyant prawn]

ok so like probably a dumb question but what is the advantage of using TMPro components over like legacy text components, almost every Brick wall I have run into coding in unity so far (still early learning but you know) has had to do with TMPro and me not being able to find good info on how it works

[hot sky]

From what I remember it is mostly just because there is finer control over the style of text, might be wrong though

[glossy eagle]

how are those things called so I can create a window that does something later please? Like I only need the name, the rest I'll try to search it haha

[buoyant prawn]

Ah i gotcha thnak you

thank you*

[fickle plume]

This is a code channel. #📲┃ui-ux for ui questions. TMP works just as basic text element when it comes to basic manipulation. And if you want more advanced usage there's a wealth information on YouTube by original creator, any cursory search would've landed you there.

[buoyant prawn]

i was asking because I have had issues with it in my code but i understand, i will use the respective channels for Components in the future, tbh I forgot they were there

[sweet flume]

Just a question

When I press the play button on unity all the buttons I've placed dissapear

[timber tide]

if (incrementInfo.abilityCastAmount > 1)
{
    void SetIncrementRange(IncrementRangeTypes rangeType, in Vector3 a, in Vector3 b, ref Vector3 unitsPerIncrement)
    {
        if (continualCastData.IncrementData.IncrementRangeTypes.HasFlag(rangeType))
        {
            unitsPerIncrement = (b - a) / (incrementInfo.abilityCastAmount - 1);
        }
    }

    //Can't use ref keyword on other structs
    SetIncrementRange(IncrementRangeTypes.StartPosition,
            continualCastData.IncrementData.PositionIncrementA,
            continualCastData.IncrementData.PositionIncrementB,
        ref incrementInfo.startPosUnitsPerIncrement);
}

How do I pass these vector3 structs as a reference which are backed by a property field with a private setter? It seems that perhaps it's the 'in' keyword I need, but examples show that the 'in' syntax is also attached when sending in the parameters yet that gives me similar errors to using ref.

[gaunt ice]

should be impossible, properties are method and you cant ref on some return register

[timber tide]

So what's the alternative here? Just don't stick your structs inside of properties?

it's really a minor thing in this scenario, but I do have some larger structs of variables so it would be silly to copy them repeatedly just to read them.

ah, even pointers have a similar problem here too eh

[gaunt ice]

return ref? forgot if unity c# allows you to do this

[north kiln]

The property would have to be a ref return

[timber tide]

oh, I see

but these values are meant to be readonly as well

[ivory bobcat]

If it's just for reading, you could use the in keyword relative to methods. With properties, it's more like accessing the actual backfield although the underlying behavior would be getter and setter methods.

[north kiln]

What do you mean by readonly here, why do you care about by reference in this case if they're readonly?

[remote lynx]

guys is there a built in method for squared distance?

[north kiln]

(b - a).sqrMagnitude

[timber tide]

in this scenario I'd have to copy the vectors to read them inside of this method

being ref is not actually ideal either I guess if they were modifiable, but it's a private setter property field

it would be in keyword I think

or ref readonly?

[north kiln]

I'm kinda confused, is the idea that you can't change the declaration of the SetIncrementRange method

and there's a compiler error because you're trying to pass a non-ref property by ref

[timber tide]

it's non-ref property

ill probably read into it more but that's probably it

[north kiln]

To be clear, if you use in with a non-ref returning struct property you incur a copy, and the copy is passed by ref

[cosmic grove]

guys what the hell is this?

[ivory bobcat]

Maybe have the structs be light weight, don't have them as structs or use a method to define explicit parameter constraints 🤔

[ivory bobcat]

Can you show the error from the console window? The image is too small.

[cosmic grove]

okay

[timber tide]

yeah it's not a big deal here, but first time I've ran into this issue which I'm surprised I've not before

[topaz pendant]

Hello, have you looked at this post ? https://stackoverflow.com/questions/59829252/unity-error-does-not-contain-a-definition-for-isgameobjectinmainscenes it seems you may have to rebuild the library folder because some files may be corrupted

[cosmic grove]

oh ok thanks

[remote lynx]

why do we use CompareTag and not tag==other?

[keen dew]

You get an error message if you typo the tag name & it's marginally faster

[remote lynx]

do i get an error or it returns null?

[keen dew]

It's a compile-time error. It always returns a boolean.

[remote lynx]

oh ok ty

[languid spire]

not a compile time error, it will throw an exception at runtime

== tag will not throw an exception, it will return false for a bad tag

[fallow knot]

Hi, why is the player twitching? I added delta time)

through the getkey component?

[keen dew]

Don't add deltaTime

[dim halo]

hey guys, so Im basically watching an old tutorial video, the guy uses 2020.3,8f1, and I have the 2021 .3.14.f1 editor would that create a problem?

[north kiln]

Don't cross-post

[dim halo]

thank you for being helpful

[fallow knot]

I am using the 2017 version course on the 2021 version and there were no problems)

[north kiln]

They have been answered in #💻┃unity-talk

[dim halo]

I'll download the 2020 just in case

[fallow knot]

small differences in the interface are possible

[dim halo]

I see

can I ask why you're using 2017?

just out of curiosity

okay, okay)

[ionic pike]

im doing an inventory and i wanna get some info from the Slot UI's with another script,im trying raycast and i get nothing i dont know how to do this

[timber tide]

That raycast won't work

if this is UI

to give you an idea why. Go into your scene and see where you UI is positioned compared to where your camera is at

[ionic pike]

i was thinking about that

but i have no idea how to fix it

[timber tide]

https://docs.unity3d.com/2019.1/Documentation/ScriptReference/UI.GraphicRaycaster.Raycast.html
Is the raycast you'd want to use, but there's also interfaces such as
https://docs.unity3d.com/2018.3/Documentation/ScriptReference/EventSystems.IPointerClickHandler.html
That's a more common approach

[ionic pike]

IPointerClickHandler does not need to be on the ui thats gonna be clicked?

[timber tide]

You stick them on components and the'll trigger

when you're over that specific gameobject

There's quite a few like IDragHandler (one of the more useful ones)

[ionic pike]

im gonna look into it thx :)

got it working

[timber tide]

noice

this will hit stuff other than the UI too I believe, but you can always iterate through for UI specific elements

[shrewd swift]

hey
can you set multiple vars with one = in chsarp ?

e.i. :

int somevar1;
int somevar2;
somevar1, somevar2 = 10;

[timber tide]

why would you var primitives

[shrewd swift]

what do you mean by that ?

[ivory bobcat]

a = b = c

[timber tide]

var is for when you don't want to type out the whole dictionary kvp

but seriously, the vs debugger has trouble with var

[shrewd swift]

ah yes, but here i am not using var ?

[rich egret]

hi i need help

someone know how to solve it?

[north kiln]

Is there a code question in "it"?

[timber tide]

oh sorry sleeping here, right Dalphat's correct then ;p

[shrewd swift]

no worries man

[rich egret]

No, it's just that every time I get close to the object it starts to disappear, it's not related to the code.

[open apex]

Hello

So I am trying to get the camera working

I can get the main camera to work like fps

I am now trying 2rd person but this code is giving me an error

could anyone explain to me why this code cannot be accepted please?

It's ok even if you have a theory to why it's not working

we can work it out together

[frosty hound]

Mouse over the error and it will tell you

But, you need to assign a Vector3

[lunar grove]

using UnityEngine;

public class AudioScript : MonoBehaviour
{
    private AudioSource audioSource;
    public AudioClip[] audioList;

    private void Start()
    {
        audioSource = GetComponent<AudioSource>();
    }
    public void DinoSFX(int sfx)
    {
        audioSource.PlayOneShot(audioList[sfx - 1], 1f);
    }
}

I get an argument null exception but I have already assigned the mp3s into my GameObject

that has this script

[swift crag]

and on what line is the error coming from?

please be specific when you're asking for help with exceptions

[lunar grove]

audioSource.PlayOneShot(audioList[sfx - 1], 1f);

this code

idk why

[swift crag]

well, you'd better start debugging

notably, what if audioSource is null?

although "argument null" makes me think this is an exception complaining you asked the audio source to play a null clip

show us the error in the console.

remember that we cannot see your screen..

[swift crag]

Okay, so that definitely means that audioList[sfx - 1] is null.

[swift crag]

to clarify: you have assigned AudioClips into your AudioScript component

you aren't putting anything into a game object

My guess is that you have several AudioScript components, and that one of them has missing clips

If you click on the exception while the game is running, the editor might select the offending object

(I'm not sure if it will here)

[lunar grove]

It's my playerobejct

but that's impossible I already audioclips into element 0 and element 1

i already assigned*

[swift crag]

Show the inspector for the AudioScript.

[swift crag]

Okay, now search your scene for other AudioScript components

you can do this in the hierarchy

t:audioscript

[lunar grove]

only my player object

[swift crag]

okay, so now we want to do some "sanity checks"

before you try to play the audio clip, log the clip and the current object

[lunar grove]

log?

[swift crag]

Debug.Log("I'm trying to play this: " + audioList[sfx - 1], this);

[lunar grove]

okay

[swift crag]

I wonder if you're creating a new instance of AudioScript at runtime. This will show if that's the case

[open apex]

Thanks for letting me know

I have fixed with a tutorial regarding vector3

but isn't it the same thing?

why wouldn't my code work?

[swift crag]

no, (1, 2, 3) has nothing to do with Vector3

We'd call that thing a tuple

[swift crag]

Looks like the error isn't happening there.

[faint agate]

I need help with something I ran into. Lets say Gun1 has 10 bullets and Gun2 has none. When I switch to Gun2, I can shoot only one bullet as if it registers the weapon switched when I click. Ill send the scripts

[lunar grove]

meaning the actual clip is there?

[faint agate]

https://gdl.space/peruxevujo.cs

[faint agate]

weapon switch script

[swift crag]

Right. The clip is non-null and there's no exception.

[faint agate]

https://gdl.space/ayedumejuh.cs

[faint agate]

gun script

https://gdl.space/awixuvibum.cs

[faint agate]

weapon shoot script attchached to player

[swift crag]

you can think of a tuple as a grouping of several objects

they're sometimes useful when you just want to return A and B from a function

(you often just use out parameters for that in C#, though)

[lunar grove]

So what's wrong then? why does it have an exception when the audiosource plays it?

[swift crag]

there is currently no exception in the console

are you seeing an exception in the console?

[lunar grove]

yes when the audio source plays it

[swift crag]

Then show me that.

I need to see what you're seeing here.

[icy junco]

i dont know if anyone can help me but i am making shooting game and have made it possible to shoot and setup a crossair in the middle of my screen but the bullets dont go to middle of my scrteen they are like of with 1 cm is there anyone who has had simmilar problem and could help me

    {
        Ray ray = playerCamera.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0f));
        RaycastHit hit;

        Vector3 targetPoint;
        if(Physics.Raycast(ray, out hit))
        {
            //hitting something
            targetPoint = hit.point;
        }
        else
        {
            //shooting in air
            targetPoint = ray.GetPoint(100);
        }

        Vector3 direction = targetPoint - bulletSpawn.position;

        float x = UnityEngine.Random.Range(-spreadIntensetiy, spreadIntensetiy);
        float y = UnityEngine.Random.Range(-spreadIntensetiy, spreadIntensetiy);

        //returning direction and spread
        return direction + new Vector3(x, y, 0);
    }```
this the code that calculates the direction

[swift crag]

oh, you know what

source is the audio source, innit

[polar acorn]

Isn't the entire point of this code to make it not perfectly centered

[swift crag]

I don't understand why you'd get an ArgumentNullException out of this, though.

[lunar grove]

what?

[polar acorn]

You're literally adding random spread

[swift crag]

Maybe if it was an extension method

[swift crag]

Check if audioSource is null.

[lunar grove]

how?

[icy junco]

but its not spreading its always on same place just a bit under my dot

[swift crag]

log it!

and ooh, I think I get it now!

here's why it's happening

when you do GetComponent<AudioSource>() and it fails, it returns an invalid unity object

it doesn't literally return null, though

When you call PlayOneShot, it winds up doing this

PlayOneShotHelper(this, clip, volumeScale);

where PlayOneShotHelper is

private static void PlayOneShotHelper([NotNull] AudioSource source, [NotNull] AudioClip clip, float volumeScale)

notice how the first argument is called source

and finally...

[swift crag]

        IntPtr intPtr = MarshalledUnityObject.MarshalNotNull(source);
        if (intPtr == (IntPtr)0)
        {
            ThrowHelper.ThrowArgumentNullException(source, "source");
        }

oh god that's frightening

[polar acorn]

Try logging x and y, see what numbers you're rolling, check if they ever change

[swift crag]

god, I don't enjoy how Unity conflates C# null with Unity's own notion of "null"

[swift crag]

You don't have an AudioSource.

Add one.

[lunar grove]

oh do I actually have to add an audio source?

[polar acorn]

It is an albatross about the neck of unity they cannot escape

[swift crag]

well, yeah

you need one so GetComponent can find one..

[lunar grove]

like my dinoplayer gameobject?

[swift crag]

it sounds like you don't understand what GetComponent does

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

[swift crag]

i've seen weirdness, but this is a new one

that was really unintuitive

"is this null?"
"well yes, but actually no"

[icy junco]

okay thx

[swift crag]

It searches for an instance of a certain type

If you call gameObject.GetComponent<Foo>(), it tries to find a Foo on gameObject

you can also call GetComponent on any Component type; it searches the component's game object

[swift crag]

and then the error it caused is one that should intuitively be impossible

this being "null" is so bogus

I expected audioSource.PlayOneShot() to immediately cause a NullReferenceException

(and it would have, if audioSource = GetComponent<AudioSource>() was never called)

it went from real null to a non-null object that Unity still considers to be null

[north kiln]

Extension methods have this behaviour regardless of Unity null

[swift crag]

Yeah, that was my first thought

and what Unity did wound up being kind of similar to an extension method

(passing this as the first argument to another static function)

[faint agate]

Can I messege or call someone to help me with someone in my game

[lunar grove]

I fixed it, added an audio source component to my DinoPlayer GameObject I kinda get at what you're saying, so I tried to add an AudioSource component and it fixed it

thanks

[swift crag]

The tricky part here was how the error appeared.

[lunar grove]

It didn't help me debug it in any way lol

hence why I was stuck

[polar acorn]

No, just ask the question here

[faint agate]

Lets say Gun1 has 10 bullets and Gun2 has none. When I switch to Gun2, I can shoot only one bullet as if it registers the weapon switched when I click. Ill send the scripts

https://gdl.space/ivaqipaqab.cs

[faint agate]

https://gdl.space/tadigodomo.cs

[faint agate]

https://gdl.space/ifelofosud.cs

[faint agate]

player shoot script attached to player

[vast vessel]

hey lads. i set up this settings menu with a volume and music slider, but it dosnt seem to be working correctly. the volume slider is setting the master volume, but the music slider is setting both the master, and music volume. what am i doing wrong? sliders and audio mixer groups have been set up correctly

wait ill send the code in a sec

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

[swift crag]

i'm guessing that's doing it

oh, you fixed it in the inspector

musicSlider.onValueChanged.AddListener(setVolume);

this sounds wrong, though

you're calling setVolume when the music slider changes

[vast vessel]

yea

this code is from a long time ago, when i followed a brackeys tutorial

i just wanted to reuse old code and not write new code

[swift crag]

well, you probably want to call setMusicVolume when the slider changes...

[vast vessel]

already done that

[swift crag]

Your code still calls setVolume

read your code!

that explains why both sliders are changing

[vast vessel]

oooooh

[vast vessel]

wait, so i dont need to set this on value changed up?

since a listener has already been added for the sliders in my code

[swift crag]

Either way works.

[lusty girder]

I have a script that is trying to set the vertices of one gameobject (a standard 3D plane) to another gameobject (also a standard 3D plane).
I'm getting an error that there is no Mesh attached to Plane gameobject. I don't see how a standard Plane doesn't have a Mesh... How can I make this work?

`public class meshgrab : MonoBehaviour
{
public GameObject grab;

// Start is called before the first frame update
void Start()
{
    this.GetComponent<Mesh>().vertices = grab.GetComponent<Mesh>().vertices;
}

}`

[swift crag]

some clarifications, first

gameobjects don't "have" vertices

a GameObject is just a thing in the world that can hold components

a Mesh is not a kind of component. I'm a little surprised that didn't cause a runtime error.

You want to grab the object's MeshFilter component

You could just reference it directly instead of referencing a GameObject

so,

[SerializeField] MeshFilter source;
[SerializeField] MeshFilter destination;

void Start() {
  destination.mesh.vertices = source.mesh.vertices;
}

I'm not sure if you'll need to do anything else after setting the vertices property

[lusty girder]

All right, I'll try that. Thank you! =]

[swift crag]

Mesh is a unity object class that represents mesh data

It won't be directly attached to a game object 'cause it's not a component

[crisp moon]

i have some questions if you all dont mind...

is 2d or 3d easier for a beginner?

what are some beginner projects because my ideas are way to complex and hard to make. like how do i com eup with an idea or know what to make?

that is all for now.

[lunar grove]

 private void Update()
    {
        GameSpeed += gameSpeedIncrement * Time.deltaTime;
        gameScore += GameSpeed * Time.deltaTime;        
        MilestoneScore();
    }

    private void MilestoneScore()
    {        
        if(Mathf.FloorToInt(gameScore) == milestoneGameScore)
        {
            audioSource.PlayOneShot(milestoneClip, 0.2f);
            StartCoroutine("MilestoneText");
        }   
    }

Anyone know why my audiosource is playing multiple audioclips even if the condition is only hit once?

the actual audio file sounds fine

when played by the game, it stacks thus making hurtful to ear to listen to

[swift crag]

if the game score increases slowly enough, it'll produce the same value when floored to an int for several frames

10.01 -> 10
10.32 -> 10
10.64 -> 10
10.89 -> 10

[lunar grove]

ah

so I just convert it into int?

[swift crag]

record the last milestone score you achieved and only play a sound if your score differs from that

[lunar grove]

comlpletely then?

[swift crag]

same problem

many score values will produce the same integer

[lunar grove]

wdym?

[swift crag]

when you reach a milestone, store that score into a variable

only play a sound if that variable is different from the current score

[swift crag]

so that the game will ignore these repeats

[crisp moon]

im not sure if this is the best place to ask this?

[swift crag]

I found 3D easier, but that's probably because I do a lot of 3D stuff already. It's easy for me to mash some assets together

You should start with something like !learn

[eternal falcon]

:teacher: Unity Learn ↗

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

[crisp moon]

thank you also i was hopeing to get into 3d becasue it seemed cool.

[languid spire]

you use your imagination. After all that is where games start, a good idea

[crisp moon]

well im just starting out and i want to make things like open would games and visual novels but they seems to hard at the moment.

[languid spire]

they are, indeed, hard to make without experience, so start simple

[crisp moon]

also sorry for my spelling im kinda dyslexic.

[timber tide]

3D is easier just because sprites are hard

[true narwhal]

i got error
u are can help me for fix this: Could not resolve all files for configuration ':unityLibrary:GoogleMobileAdsPlugin.androidlib:detachedConfiguration2'. See the Console for details.

[crisp moon]

what about 3d movement/animations? are they not as hard?

[swift crag]

Don't spam every chatroom.

[true narwhal]

okey

[swift crag]

This is a #📱┃mobile problem

[timber tide]

3D animation is easier than 2D since you just lerp values

while 2D sprites you're drawing every frame

[crisp moon]

that makes sense

[timber tide]

of course there is resources to cheat 2D animation, but there's more popular methods of making 3D assets look 2D to get the benefit of animating them in 3D

[crisp moon]

im starting to think maybe i should make an fps or is that too hard? as i said i dream big.

[languid spire]

still too ambitious, learn to walk before you try to run

[lone sable]

Without just firing me off the ide command...

Anyone else having issues with VSCode not showing default Unity information? EG: It doesn't show me void OnEanble auto completes etc?

It used to work perfetly fine, but, I assume something got updated somewhere and now something is broken.

[timber tide]

fps is actually a little more intermediate because you're dealing more with rotations. A lot of games you can get away with just rotating on a single axis or even disabling rotation completely and moving using world coordinates with velocity.

[ivory bobcat]

Just want to inform you that making games overall isn't easy

[crisp moon]

platfomer in 3d?

[crisp moon]

i know but its kinda my dream to make one.

[languid spire]

yep, not a bad idea

[crisp moon]

i would like to say thank you all for helping.

[ivory bobcat]

Target a particular game and try to clone it

[languid spire]

I always suggest implementing existing board games because you don't need to focus on the game play, just the implementation and visuals

[lunar grove]

I couldn't really get what you meant, but I just decided to have a bool flag to check if the audio was already played once, then resetting the flag after the my CoRoutine ends since they go hand in hand anyway

[swift crag]

int lastMilestone;

public void TryMilestone(int score) {
  if (lastMilestone != score) {
    lastMilestone = score;
    PlaySound();
  }
}

like so

[faint agate]

was anyone able to look at my scripts

[lunar grove]

Wouldn't just that make it so that as the score increases the method gets played over and over again?

[swift crag]

presumably you'd call TryMilestone only when your score equals the milestone score

you could also just calculate a new milestone score whenever you reach a milestone

[sullen zealot]

hello! if i setactive to false one object then seti it true acaig, will it restart?(like the scripts, will they execute the start function again?)

[swift crag]

No.

Start runs once.

OnEnable runs many times, though

[sullen zealot]

ok thanks

[lunar grove]

I mean that's what I intend to do anyway

[swift crag]

in that case you don't have to check for duplicates at all

[lunar grove]

I mean only at certain points it would recalculate like at 1000 pts it would change the milstone from 100 to 250

something like that

[sullen zealot]

and can i call script functions from other scripts while the gameobject is not active?

it doesnt

[cosmic quail]

yes you can call a function on a non-active gameobject. or what do you mean?

[sullen zealot]

it didnt work for me. i found another way

[eternal needle]

Another way to call a function? Show what you were trying. You definfitely can call functions on inactive gameobjects.

[polar acorn]

Calling a function works fine. Find does not

[sullen zealot]

this is the settings script

[polar acorn]

Get the reference first

[sullen zealot]

oh

thanks

[polar acorn]

In general you should probably just avoid any and all functions with the word "Find" in their name

[sullen zealot]

does it affect performance?

bc i use it a lot in most of my scripts

[timber tide]

if you're doing it in update, yes

or doing multiple find operations in a single update

[rare basin]

in general you should never use any Find() method, there might be some special uses in Awake() or Start() only for singletons etc

[sullen zealot]

no im only using it in start or other events

[rare basin]

imagine you change your object name in hirearchy

and your scripts doesnt work

Find() type methods are terrible - dont use them

[sullen zealot]

is getcomponent also bad to use often?

[wraith mango]

What is an alternative?

[ivory bobcat]

Yes but there are special circumstances where you're probably going to call the function. It's not as terrible as find where you'd search the entire hierarchy or children of a transform etc

[sullen zealot]

and what could i use instead of this?

[sullen zealot]

i googled it and the best way its to just use [SerializeField] Transform . GetChild is also bad apparently

[ivory bobcat]

Properly reference where you can and use it as less often as you can - physics callback methods would probably be a valid scope to use get component.

[rich adder]

serialize the field and drag the reference, the object is already its child. Find method is unnecessarily brittle

[wraith mango]

alr

[wraith mango]

is anyone here able to look at this rq

[rich adder]

i dont understand the question here, can you explain

[wraith mango]

there is a white space in between "objectives" and the actual objective, which would be fine but when I try to register that objective as completed, it thinks that the objective is in that white space

if that makes sense

[spring skiff]

Is there a better solution as this script?

using UnityEngine;

public class SoulFragement_Anzeige : MonoBehaviour
{
    [HideInInspector] public int SoulShards_collected = 0;
}

I mean its really everything needed.
I have 30 scripts that needs to interact with this integer.

[rich adder]

better to do what?

[spring skiff]

maybe a premade parameter conponment that I dont know about?

[rich adder]

what are you trying to do exactly

could look into props

[swift crag]

So you need several components to be able to share a value.

[rich adder]

use a SO

[swift crag]

using scriptable objects for sharing mutable data is fun, but can also very confusing for the inexperienced

[rich adder]

true

[swift crag]

I think what you're doing is reasonable.

[spring skiff]

yes.
and making a script for just 1 line of code seems a bit out of place of everything other script does the work and this script is only there to contain a simple integer where every other script can have access to it, no matter if some other scripts get destroyed together with the gameobject.

[rich adder]

I'm still kinda confused on the issue sorry

[swift crag]

There might be a better place to store the value, of course, like on a "player" component

if only players can have soul shards

[spring skiff]

if a gameobject gets collected by the player, it access the script, make "SoulFragement_AnzeigeSCRIPT.SoulShards_collected++; and destroys itself.

[swift crag]

sounds like you have an extra object in there, then

[rich adder]

i think problem is description

description might have the extra whitespace?

[wraith mango]

ooh that's true one sec

it doesn't appear to have one

oh wait

wrong screenshot

but still

[cosmic quail]

how do u get your list looking like that in the inspector?

[wraith mango]

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

[CreateAssetMenu(fileName = "New NPC", menuName = "NPC")]
public class NPC : ScriptableObject
{
    public new string name;
    public string[] messages; 
    public string[] objectives; 
}

[rich adder]

custom class

[cosmic quail]

its just a string[] though. or is that what it looks like in the newest unity version? i havent tried

[queen adder]

how do I post my code like this format ?

hello guys, so I am following Code monkeys complete tutorial for beginners and although it's fun I have a problem with this code, i have been trying to fix for a bit now (1 hours ish and its driving me crazy)

[rich adder]

entire class does not belong inside Inline

use the proper sites

[queen adder]

I mean

tehre is a few extra }

and lines they are just irrelevant

to problem

and discord has caracter limitqs

so couldn't past whole code

[rich adder]

put debug.logs like Debug.Log($"Objectives String:\n{objectivesString}"); and check UpdateObjectivesText for example

print them all

[queen adder]

basically whenever my character moves, it does a complete U turn before turning

[rich adder]

so you decide how to share code? thats not up to you to determine

its annoying to read on mobile and line numbers/formatting

[queen adder]

okey I am sorry

[wraith mango]

use hastebin

or pastebin

[rich adder]

use the sites linked..

[queen adder]

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

[rich adder]

also share the tutorial because you probably copied it wrong

[queen adder]

https://www.youtube.com/watch?v=AmGSEH7QcDg

timestamp : 2:14:00

I tried with and without f in the Vector3 though as expected it didnt change anything, I thought maybe the problem was that when I put moveDirX or Z the normal value of the vector is no longer 1 but it should have made an error for him too / didnt work when i tried to fix it in the transform forward

[wraith mango]

ty for the help, it was an issue with how i was placing the new lines \n

[rich adder]

can you record a video of your issue

also are you sure the pivots are correct

[queen adder]

should be, I didn't invent just copiing the code then pausing to understand what just happend

(video is loading)

[rich adder]

should isn't certainty be sure

[queen adder]

well i double checked in the video its the same code for pivots, but I do think problem is with them

" transform.forward = Vector3.Slerp(transform.forward, moveDir, rotateSpeed * Time.deltaTime); "

I think problem is in this line

just don't know how to fix it

[rich adder]

yeah code monkey writes kinda bad code

[queen adder]

well he for sure claims a lot that his code is good practice and game publishing worthy lmao 🤣

he said it like 10 times in the first 2 hours

[rich adder]

yeah and im the president

[queen adder]

🤣

what country

[rich adder]

world

[queen adder]

nice

[rich adder]

anyway can you show the pivots

in Local Pivot mode

[queen adder]

excuse my ignorance

where do i find that

[rich adder]

select the player object with the movetool and check the scene is set to Local Pivot

its in the upper left corner

I dont have unity open rn

[rich adder]

hopefully its not in center mode and got all offset

[queen adder]

what does that mean ?

and yeah it's in Pivot Local like shown here

[queen adder]

Thank you btw :

[rich adder]

can you show it with the movetool on the player object

[queen adder]

Yes, video loading

[rich adder]

oh ok screenshot would be fine

[queen adder]

ok i stopped the video ( i have bad internet)

but basically with this I did a test and it still doesnt the same thing

[faint agate]

can someone help me with a problem I ran into. Lets say Gun1 has 10 bullets and Gun2 has none. When I switch to Gun2, I can shoot only one bullet as if it registers the weapon switched when I click. Ill send the scripts

[rich adder]

pivot looks okay

[faint agate]

https://gdl.space/udosukiled.cs

[faint agate]

thats the weapon switch script

[rich adder]

what about Player itself

not PlayerVisual

[faint agate]

https://gdl.space/sihomagiro.cs

[faint agate]

thats the gun script

[queen adder]

same

[faint agate]

https://gdl.space/zugubohofe.cs

[faint agate]

thats the player shoot script attached to player

[rich adder]

wouldnt it have made more sense making 1 message with all the scripts instead of this scattered thing

[rich adder]

same what

show

[queen adder]

Pivot Local

[rich adder]

do you see the problem..

obv not

lol

you're rotating that spot

[queen adder]

XD

AHAHAHAHAHA

ok

i see

sorry

[rich adder]

look how far the mesh is from the main object pivot

[queen adder]

I moved the playervisual earlier

to try smth

[rich adder]

all you need to do is reset

[queen adder]

sorry lol

[rich adder]

the position of the PlayerVisual

[queen adder]

after he does smth I pause the video and mess arround to understand more

and i forgot to put the visual back

my bad

good evening lads

[rich adder]

its fine, is it fixed?

[queen adder]

sorry for wasting your time

yes it is

[rich adder]

all good

see these "courses" dont teach these importance caveats of the editor

[faint agate]

would you be able to take a look at the messeges I sent

[queen adder]

I agree, but gotta start somewhere 🤷‍♂️ and his course is a bit entertaining

but if you have any recommendations I would love to have them !

and i will do them as soon as finished with this one

[rich adder]

I would browse !learn

[eternal falcon]

[queen adder]

Noted, will do ! thanks again

[rich adder]

which one you sent many

[faint agate]

Lets say Gun1 has 10 bullets and Gun2 has none. When I switch to Gun2, I can shoot only one bullet as if it registers the weapon switched when I click. Ill send the scripts

https://gdl.space/sihomagiro.cs
thats the gun script

thats the weapon switch script

https://gdl.space/zugubohofe.cs
thats the player shoot script attached to player

[ivory bobcat]

Figure out why it can still shoot
#💻┃code-beginner message

[lunar grove]

Can someone enlighten me with how the t argument from the color lerp works? I want to have a fixed transition time between two colors in my game

[rich adder]

https://unity.huh.how/lerp/overview
incase you write it with time.deltatime this explains more why people write it wrong when using thathttps://unity.huh.how/lerp/wrong-lerp

[ivory bobcat]

t should be a value that goes from zero to one - not a fixed value.

[swift crag]

Mathf.PingPong returns a value that "ping pongs" between 0 and the second argument

based on the first argument

so 0 -> 1 -> 0 -> 1 -> ... here

[faint agate]

I don't know how I would check if it happened at the same time or delay

[ivory bobcat]

Put a log in the on disable callback and see if it prints

[languid spire]

move your subscribe
PlayerShoot.shootInput += Shoot;
PlayerShoot.reloadInput += StartReload;
to OnEnable
and unsubscribe in OnDisable
also here
foreach (Transform weapon in transform) {
if ( i == selectedWeapon )
weapon.gameObject.SetActive( true );
else
weapon.gameObject.SetActive( false );

        i++;
    }

add Enable disable of Gun script

[ivory bobcat]

Pseudocode progress += Time.deltaTime/duration color = lerp(initial, target, progress)

Implies that the default duration should be 1f

[lunar grove]

Ok, I'm starting to understand, but I need more studying it appears, having trouble comprehending

[languid spire]

think of t as %age complete where 0 is 0% and 1 is 100%

[lunar grove]

so saying that value traveling from 0 to 1 is the time it takes for it to switch colors?

[languid spire]

yes

[swift crag]

it's how far you've transitioned from the start value to the end value

[ivory bobcat]

t would be the percentage of transition between the first and second

Where the first and second are constant but t accumulate towards 1 (100%)

[lunar grove]

So lerp has to be in an update function for it to work smoothly?

[languid spire]

or a coroutine

[ivory bobcat]

For example, using age years += ... age = lerp (child, elderly, years)

[faint agate]

it prints

[swift crag]

Lerp gives you a value between two other values. That's all it does.

A common misconception is that calling Lerp once will make something "move on its own", or otherwise smoothly change over time.

If you smoothly change the value of t and repeatedly call Lerp, the resulting values will smoothly change over time as well

do it in Update, do it in a coroutine, do it in a method that something else calls from their Update, do it in FixedUpdate...

void Start() {
  foo = Mathf.Lerp(0, 1, bar);
}

This will set foo exactly once when Start runs.

it's no different, conceptually, from just doing

void Start() {
  foo = 0.5f;
}

[faint agate]

I'm having a hard time implementing the last step. I made a gameObject to attach the script too, but when I I do

         else
            weapon.gameObject.SetActive( false );
        GunScript.SetActive(false );

I get an error.

[languid spire]

weapon.GetComponent<Gun>().enabled = false;

[ivory bobcat]

The conditions are true so the object to shoot for the gun will still occur. As to why it's not Gun1, I'm not sure because we weren't shown when you logged Gun1

Only Gun2 should ever log according to your code

[languid spire]

no, because all guns are always subscribed to the events set up in Start

private void Start()
{
PlayerShoot.shootInput += Shoot;
PlayerShoot.reloadInput += StartReload;
}

[faint agate]

I changed this to onenabled

[languid spire]

well repost your latest code

[faint agate]

foreach (Transform weapon in transform) {
if ( i == selectedWeapon )
weapon.gameObject.SetActive( true );
weapon.GetComponent<Gun>().enabled = true;
else
weapon.gameObject.SetActive( false );
weapon.GetComponent<Gun>().enabled = false;
Debug.Log("switched");

with this I get an error with the " weapon.GetComponent<Gun>().enabled = true; "

[languid spire]

so the Gun script is not on the weapon gameobject?

[faint agate]

it is

[languid spire]

also you will need to add braces

[faint agate]

I added them and now I don't get an error. When I switch from Gun1 to Gun2 it prints " Gun2 " and if I switch back it prints " Gun1 " . If I switch from Gun1, the script(Gun) attached to Gun1 disables, but I can still shoot only once

[languid spire]

so show your latest Gun script

[cosmic grove]

guys a simple question. is a ray every frame bad? like 5-6 rays per frame would cause noticable lag?

[faint agate]

https://gdl.space/abudizakuj.cs

[ivory bobcat]

Rays are cheap

[rich adder]

a ray is just a struct, extremely efficent

you mean Raycast ?

[languid spire]

Now read what I initially wrote

[cosmic grove]

yea that

[cosmic grove]

oh ok thanks

[swift crag]

i'd be doomed if 5 raycasts per frame made your game lag

[rich adder]

there goes my enemy ML agent car 😦

i think it has like 12

[cosmic grove]

i underestimate a computer's peformance. coming from a guy who used to own a intel 4gb ram mac

i mean this one isnt much of a upgrade either but yea.

[languid spire]

4gb, my first computer had 4k

[rich adder]

should focus on the higher dips in FPS like Poly count, poor LOD, Post Processing, Batches etc.

[cosmic grove]

yea i do that . tho i need to know more about post processing. ill check up on that later

[lunar grove]

Thanks for the help about color lerp, everyone I'll just continue tomorrow as I'm still having problems trying to apply it to my game

[faint agate]

https://gdl.space/vidacozafa.cs
is this what you mean

[rich adder]

what are you trying to do with it ?

[languid spire]

I said UNSUBSCRIBE

[lunar grove]

Simply transitioning from one color to another that is triggered by an if condition

then I would transition the same colors again vice versa from another if condition

[rich adder]

oh so jjust get rid of the ping pong ?

[lunar grove]

I did, I tried a coroutine and it felt weird, especially the color transition wasn't there, but I think you mean I would just put Time.time as t?

[rich adder]

https://gamedevbeginner.com/the-right-way-to-lerp-in-unity-with-examples/#lerp_material_colour

here shows how to correctly do color lerp

[candid drift]

im super new and i just closed my hierarchy where did it go 😭

[rich adder]

not a code question

https://docs.unity3d.com/560/Documentation/Manual/CustomizingYourWorkspace.html

[candid drift]

where do i go to ask this question

[faint agate]

how would I do this

[rich adder]

#💻┃unity-talk

also just reset the layout if you're confused

[lunar grove]

Oh thanks a bunch!

[languid spire]

well if
PlayerShoot.shootInput += Shoot;
is subscribing
what do you think unsubscribing would look like?

[faint agate]

ahhh I got

[languid spire]

i.e the opposite of += is...?

[faint agate]

it workeddddd

thank you so much steve!

[lunar grove]

Also wished I could have understood how lerp worked better to not trouble all of you trying to explain it me that much lol

[rich adder]

no worries! its confusing at first , but if you think of it like it was suggested where it just represents a % between 0-100 it start to make sense the more you use it

[lunar grove]

I see, thank you so much again for helping me out!

[rich adder]

no problem 🙂

[spring skiff]

Now I have a fully working raycast and I think I should had better used a trigger with a 1.5meter long invisible collider in the middle of the camera...

Because I have some hiding spots that uses triggers and colliders and it seems that the invisible triggers and colliders does block the raycast and I cant collect items in a wardrobe.

[frosty hound]

You can layer mask the raycast

[spring skiff]

but on what exactly?
what layer does the gameobject with the raycast script need? it seems just every collider or trigger blocks the raycast.

[languid spire]

you use the layermask to hit the objects which are on the layers you want or to exclude the objects on the layers you dont want. Your choice

[spring skiff]

but how can I tell it to pass though the object with the wrong tag?

[languid spire]

not tag, layer

[frosty hound]

You don't, you use layers

[rich adder]

raycast are physics so they go by colliding with each other through Layers
its what helps control interaction between physics object

[thorn holly]

So say I had this weapon in the players inventory that gains more damage when an enemy dies. The only way I can think to do this is for the enemy to create a reference to the player, and then when it dies, see if the players inventory contains that specific weapon, and if it does, change the stats of that weapon. I feel like there has to be a more efficient way to do this, but I can’t think of any.

[spring skiff]

I dont have any layers included in my code.
Only one "selection.CompareTag"

[rich adder]

the layer parameter is in the Physics Raycast function, it helps "filter" what to hit

[languid spire]

do you even know what a Layer is?

[silver sun]

hi everyone i've spent 3 whole hours trying to leave the code intact while still adding a new variable that controls how intense the speed of each planet slows down when it gets closer to the planet with + 1 index than the current index and speeds up when getting further, i was hoping someone here could give me an idea and end my suffering. Here's the working code without the desired behaviour i said above:

https://pastebin.com/cnDafNgq

[rich adder]

https://docs.unity3d.com/Manual/use-layers.html

[languid spire]

define speed...slows, rotation? movement? Cheese production?

[silver sun]

Cheese production please.

||Position||

[languid spire]

can't slow down cheese production, the goats don't like it

[spring skiff]

how can I tell it to ignore every layer besides "walls
I cant see anything with a string name that says whats the layer name.

[frosty hound]

You create a layer mask

[spring skiff]

only confusing stuff "int layerMask = 1 << 8;"

[rich adder]

dont worry about bitmask rn use layermasks

[languid spire]

whats confusing about that

[rich adder]

[SerializeField] private LayerMask whatToHit

[spring skiff]

int 1 is smaller, is smaller than 8. why 8? IDK....

[rich adder]

nah those are bitshifting

[cosmic quail]

< is smaller, << is something else

[languid spire]

modern day child devs, not a clue what a bit is

[rich adder]

https://unity.huh.how/bitmasks

[polar acorn]

Okay there's plenty of people who don't understand basic concepts but this one is actually a pretty complicated bit of syntax and functionality

[rich adder]

they're here to make a game though not general hardware/software knowledge..

give them a slack

[polar acorn]

It's a bit unfair to give that response about bitmasks in beginner code

[rich adder]

agree, they are confusing already as is let alone in beginner gamedev

[thorn holly]

Is there a way to like broadcast a signal and then any classes with specific code to take that signal can then say, execute a method?

[polar acorn]

That, my friend, is exactly the right question to ask.

Here's the working code without the desired behaviour i said above:

https://pastebin.com/cnDafNgq

[thorn holly]

Let me guess, events and delegates do EXACTLY what I just described

[polar acorn]

Yep. Incredibly useful. You'll start to see the use cases for these everywhere once you understand em

[thorn holly]

Awesome, thanks

[lone finch]

how to only change rigidbody2d velocity y vector

[lunar grove]

I've studied events and delegates in C#, how to they differ in unity?

[languid spire]

they dont

[lunar grove]

Ah so the title of the video was for more practical uses in Unity then?

[balmy yacht]

Hey, not really a coding question but i'm using the Super Character controller, but it's not working as expected, the character moves but only forwards and back, and moving left or right moves the camera, In the scene if i move the character around the camera seems to be attached to the player but in game it is not. I would like the camera to follow the character and mouse movement points where the character should be walking

[languid spire]

Unity has it's own implementation UnityEvents and UnityActions but basic c# ones work even better

[lunar grove]

Ah, I see thanks

[jolly jewel]

u can get individual axes with Vector2.y so just assign that

[lunar grove]

Mario in a summer shirt

[balmy yacht]

it seems that the "actual" player is not aligned with the model

and the camera seems to be acting like first person???

it has a function to tick either first or 3rd person... strange

it's betetr once i align it with the model but the camera still doesn't follow the character

[thorn holly]

@polar acorn so I think I understand delegates, I just had a question. Should I have a script that only holds delegates, like a sort of delegate hub script to make adding methods to the delegates easier?

[polar acorn]

You could, but it's probably better to define the delegate on the thing that has the event

Since it's the thing that needs it, it's nice to see them all in one place

but there's no real performance or anything ther

[languid spire]

Firstly you will need a tupple array the same length as planets
(float prev, float next)[] planetDistances
so you can keep track of the distance per planet from the previous and next planet in the system
and maintain this in Update.
Let me know when you've implemented this

[thorn holly]

Ah i see, so I should declare it on whichever script activates the delegate?

[queen adder]

hey guys, is there a way to integrate Dali Ai into unity? Want it for a game as an image generator

experimenting with generative ai in 2d games

[rich adder]

if it has an API then why not..

most stores ban AI like that though so you cannot earn on steam at least

[queen adder]

oof

[ivory bobcat]

var velocity = rb.velocity;
velocity.y = ...
rb.velocity = velocity;```

[spring skiff]

It was really confusing but I finally figured it out what you meaned by this. thanks.

[rich adder]

good stuff!

[languid spire]

@silver sun Actually forget what I said
Your best bet is to scrap your planetSpeeds array and implement a Planet class containing the following
Transform
Speed
DistFromPrev
DistToNext

and then you can implement simple methods to maintain these values

[silver sun]

👍

Transform for what purpose?

[languid spire]

so that you can pass the transform of the prev and next planets into a method and use the transform to calculate the distance between them

[lone finch]

why can i not use transform.position like this?

[timber tide]

what's the error

[languid spire]

because it's a property

[rich adder]

https://unity.huh.how/compiler-errors/cs1612

[ivory bobcat]

Position is a property and not an actual field

[rich adder]

properties are just fancy methods 🙂

[timber tide]

should be capitalized though

[ivory bobcat]

I know right

[lone finch]

so i need to declare a new variable and change position by the variable?

[languid spire]

yes

[rich adder]

did you look at the link I sent

it explains the fix too

[languid spire]

and then set it back

[lone finch]

yeah

[ivory bobcat]

When you attempt to access the y component of the position property, you end up calling the getter that returns a copy of the Vector3 struct. Modifying the copy will not affect the actual backfield member of the property.

[edgy fox]

how do I send a whole unity project for someone to test with - I have a really weird bug that someone couldnt fix even after I followed all of their suggestions and they suggested I send it to someone who can test it and find what could possibly cause said bug

[languid spire]

Assets->Export / Assets->Import

[edgy fox]

alright thanks!

[rich egret]

someone know why the font like this?

[rare basin]

this is a code related channel

[robust kelp]

how can i limit rigidbody.velocity without clamping it and can i limit only vector3 x and z values

plz help

[rocky canyon]

you can adjust teh x and z values seperately..

combine them all together and then pass a new vector

[swift crag]

remove the Y component, do your clamping, and then put the Y component back in

[rocky canyon]

or that ^

[swift crag]

horizontal = Vector3.ProjectOnPlane(vel, Vector3.up);
vertical = Vector3.Project(vel, Vector3.up);

// do something to horizontal

vel = horizontal + vertical;

[rocky canyon]

not sure how one can limit it w/o clamping it tho

[swift crag]

this would work with any axis, not just the Y axis

[rocky canyon]

even if u wrote ur own if()else() conditional to stop it from going over or under, thats still a clamp

[swift crag]

useful if you want gravity to change directions (and just more pleasing to look at, IMO)

[robust kelp]

or clamp whatever will work

[swift crag]

i need to try making a game with tons of gravity shifitng

[short hazel]

Normal. As its name suggests, Text Mesh Pro uses meshes to display your text. And to display a mesh you need a material, and to render a material you need a shader. They are the two things that appear when you expand the font asset. The converter creates a SDF (signed distance field) shader, and a material for your font.

[swift crag]

The material preview looks really funky because it's not exactly meant to be drawn on a sphere

[rich egret]

ty

[swift crag]

Also, if you're curious, those two things are sub-assets

similar to what you see on an imported model

[rich egret]

so how to solve it?

[short hazel]

Solve?

There's no apparent problem here

Or you forgot to add it in your original question!

[rich egret]

It doesn't count it as a font

[short hazel]

What makes you say that?

[rich egret]

can't put it in

[short hazel]

What steps did you do to create that font asset?

[rich egret]

I downloaded a font from the internet, did font assess creator and put it in the file.

[rich adder]

are you sure it was the TMP one ?

screenshot it

[rich egret]

YUP

[rich adder]

also not really code issue 😛

[short hazel]

Your font doesn't have the same icon as the one in the TMP_Text right now. It should also be the blue "F", instead of the generic scriptable object icon.
When creating the font asset, did the utility display any errors?

Also what's the extension of the font you downloaded? And optionally make sure its license allows embedding it in software

i have this code that gives 2 rawimages a render texture. is there any way to make the first one remain the same after assigning the render texture to it? bc if i move the camera right now both raw images modify

[rich adder]

you're assigning the same texture ofc its gonna modify them both

store it inside a variable?

[sullen zealot]

what kind

[rich adder]

Texture ? RenderTexture ? w.e u want

probably better to store it as RT if you need to do RT specific stuff after without having to cast from inherited Texture class

[swift crag]

if you don't want the first image's contents to change..don't change them

[sullen zealot]

i tried this and it is still updating

[swift crag]

just reassigning variables does nothing
