Lerp is something that needs to happen over the course of multiple frames. You can't do it in one frame like this

[clever spade]

Lerp interpolates between a value of 0 to 1. As 0 increases towards 1, the same reasoning happens to point a. It will increase towards point b.

GetComponent<Rigidbody2D>().position.y;
this is to get position of current object that has script. how do i get position of a different game object?

oh iknow

maybe

[somber nacelle]

get a reference to the object you want to get the position from. how to get a reference: https://www.youtube.com/watch?v=Ba7ybBDhrY4

not really sure where this question might go, but i'm having this issue where unity forcibly takes application focus after domain reloading (e.g. after making a script change in visual studio). i think this started happening after i upgraded to 2022.2. anyone know how to disable this behavior?

[mental sparrow]

audio.Play();
does this not work with prefabs?

i read something about the prefab instance getting destroyed before it can play the sound but even without destroying it it's not working for some reason

audio is an AudioSource

Hey is it in any way possible to have an infinite tilemap for a sidescroller? Using ruletiles and adding pre-made segments or rooms to the right side but always connecting those rooms using the ruletiles rules? I cant find anything about this on google?

If yes, how would I do it? Make the pre-made segments their own tilemaps as prefabs? Another way? How do I spawn them in so the ruletiles connect to the other segments?

Any help is much appreciated!

[regal ore]

okay wow so i figured it out - if you have multiple unity projects open, any domain reload will force the project whose domain is being reloaded to take application focus, even if your previously focused application isn't unity.

Hey
I have error SerializationException: Type 'UnityEngine.ScriptableObject' in Assembly 'UnityEngine.CoreModule, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable., while my ScriptableObject is serializable (I guess)

[leaden ice]

you don't want/need [Serializable] on a ScriptableObject derived class ever

What are you trying to do when you see that error?

[grim flax]

Well, I created SaveSystem and I get this error when I want to save player inventory

return (Dictionary<string, object>)formatter.Deserialize(stream);
I guess it is this line

But i am not sure

[leaden ice]

You should never use BinaryFormatter

period

and Dictionary<string, object> is just an insane thing to use too.

[grim flax]

If be honest
I did it from tutorial cause I have not idea how it could be done
So I used to use trailer and change it on my way

[leaden ice]

https://learn.microsoft.com/en-us/dotnet/standard/serialization/binaryformatter-security-guide

find a different tutorial

[grim flax]

May you want to share some another tutorial for save system?

ah ok

[verbal grail]

Thx. I'll post there.

Is there a way to set a variable that can be accessed by any class without the need of instantiating, like a static method? For example, setting a material to that variable that any class can simple call MaterialScript.material to get

[leaden ice]

Static variables

but they're often not a good idea, you're fully responsible for their lifecycle

[shy spire]

I tried them, but they didn't work how I expected, i.e., you still have to set the variable in runtime. I was more looking to something that could be set in the inspector, like you do on classes that are on objects, but on a script itself, but that doesn't seem to exist by my trial and error.

[leaden ice]

ScriptableObject can serve this purpose

Or just use a singleton

[serene geode]

hey how would I set an integer to a gameobjects place in the array?

[shy spire]

I'll research both, thank you for the tip

[serene geode]

So, each object in this array has an integer called "placeInArray"

I want to set that integer to its place in the array of a separate manager object

[leaden ice]

for (int i = 0; i < myArray.Length; i++) {
  myArray[i].placeInArray = i;
}```

[serene geode]

and this is an update function?

[leaden ice]

heavens no

More like Awake of the manager

[serene geode]

Okay so the problem is that objects get added to the array over time...

[leaden ice]

You should be using a List then, not an array

[leaden ice]

and that's simple:

public void AddAnObject(MyScript objectToAdd) {
  int listLength = myList.Count;
  myList.Add(objectToAdd);
  objectToAdd.placeInArray = listLength;
}```

[serene geode]

I see, thank you

[grim flax]

Can I ask why should not I use Binary Formatter?
Every next tutorial I am looking in uses it

[leaden ice]

I showed you why already. Look at different tutorials

[serene geode]

and the "MyScript" here would be referring to the script attached to the individual objects?

[leaden ice]

So, each object in this array has an integer called "placeInArray"
It's whatever class that is

[serene geode]

Got it, thank you

[reef crater]

banner shows up in unity editor, but not when i build it on my iphone

[shy spire]

Doesn't seem to be what I'm looking for. I need a variable that can be set outside of runtime, like a static method that doesn't need its class to be attached to an object to function. Anything that I have to create in-scene will not work. I've settled on an static variable being set by the game controller on awake.

Hey Guys, I'm Currently developing a platformer with a shotgun as the main gimmick. Basically when the Player shoots the shotgun, the Player should fly backwards with wanted value.
My Problem is, that while getting the angel for the desired direction, the cursor changes the amount of the force depending where it's currently on the screen.

Since I want a constant value for the knockback, dose anyone know how I could change the Formula so that the cursor affects only the direction and not the force applied to the Rigidbody?

Code I'm currently using:

// This is all the needed Code moved Into the shoot Function (meaning some variables are declared elsewhere)
private void Shoot()
{
  mousePos = cam.ScreenToWorldPoint(_context.ReadValue<Vector2>());
  _force = new Vector2(mousePos.x - transform.position.x, mousePos.y - transform.position.y);

  rb.AddForce(-_force * knockbackForce, ForceMode2D.Impulse);
}

If I should provide more Info or examples, ask :)

[south crag]

Normalize the force vector to be of unit length (removes magnitude, keeps only direction) and then multiply that unit vector with your desired knockback force.
i.e.

_force = ...
_force.Normalize(); // makes it unit length
rb.AddForce(-_force * knockbackForce, ForceMode2D.Impulse);

[north frost]

Gimme a sec, going to test that real quick

[south crag]

At that point, _force needs renaming to something like forceDirection or the like, to reflect its intent

[north frost]

It works! Thank you :)

[leaden ice]

ScriptableObjects are not in scene

They are assets

[tired tulip]

how would you make a climbing system with animation rigging package in unity, more specifically with IKs

[trail mist]

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

public class Hover : MonoBehaviour
{
    public LayerMask layerMask;
    public Camera mainCam;
    public bool IsHovered = false;
    public GameObject selectedobject;

    void Update()
    {

        int NoOutline = LayerMask.NameToLayer("NoOutline");
        Ray ray = mainCam.ViewportPointToRay(Vector3.one/2f);
        if (Physics.Raycast(ray, out RaycastHit hit, Mathf.Infinity, layerMask))
        {
            if (hit.transform.tag == "Hoverable")
            {
                hit.transform.gameObject.layer = LayerMask.NameToLayer("Outlined");
                Debug.Log("Changed layer to layer1");
                selectedobject = hit.transform.gameObject;
                IsHovered = true;
            }
            else
            {
                IsHovered = false;
            }
            if (IsHovered == false)
            {
                if(IsHovered == false && selectedobject != null)
               selectedobject.layer = NoOutline;
                selectedobject = null;
            }
            
        }

    }

}

i made this script so that when i hover objects with the tag hoverable , it will change the layer of the object , change the bool value ,and when im not hovering anymore , it will change the bool value and the selectedobject will change it's layer before making the selected object null

bug : when i hover on obj1 then obj2 , with both of them having the tag , the first hovered gameobject dont swap layers too
how can i detect this object change so i fix this bug ?

[shy spire]

Oh, from what I saw you had to use it into a scene for it to function, tomorrow I'll check it out again

[leaden ice]

they literally cannot exist in a scene

they are assets

you have to reference them to access their data of course

[shy spire]

Sorry, that's what I was trying to say, but I'll check them out nontheless

[brisk reef]

Hey, asking it here again because #💻┃code-beginner is busy, I used the Brackeys guide to set up movement using a 3rd person camera, and I wonder how I can make it, so the direction which the character is facing is always relative to the camera, and not the movement?

    void Update()
    {
        horizontal = Input.GetAxisRaw("Horizontal");
        vertical = Input.GetAxisRaw("Vertical");
        Vector3 direction = new Vector3(horizontal, 0f, vertical).normalized;

        if(direction.magnitude >= 0.1f)
        {
            float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg + cam.eulerAngles.y; //Determine which way the character should face
            float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime); //Take the targetAngle and smoothen the turning a bit
            transform.rotation = Quaternion.Euler(0f, angle, 0f); //Set the rotation to the angle
            Vector3 moveDirection = Quaternion.Euler(0f, angle, 0f) * Vector3.forward; //Make it so the way forward is relative to the camera
            controller.Move(moveDirection * speed * Time.deltaTime); //Move the character
        }

    }```

[clever spade]

transform.forward will give you a direction the player is facing

[brisk reef]

yeah, I want that to be relative to the camera essentially

[clever spade]

well now you want conflicting results

[brisk reef]

wait

wrong video actually

[brisk reef]

It's a little hard to explain

you know how a lot of 3rd person games have 2 camera types

[clever spade]

over the shoulder, fixed, and free

quite a few

[brisk reef]

actually

over the shoulder sounds like it

kinda like aiming

A good example is GTA5

[clever spade]

So you want the rotation to be independent?

[brisk reef]

while moving normally you can go in any direction

[leaden ice]

it's called third person with strafing

[brisk reef]

but while holding down on the sight, you can strafe left and right

[brisk reef]

thanks!

yeah that's basically what I want to achieve

how can I do that?

[clever spade]

The camera has to be positioned around the player. Start there with some algorithms related to circles

hint, Cosine Sine

[brisk reef]

I used Cinemachine for that

[gilded schooner]

Hey

I want to know how to do a jump that increases in height the longer you have the jump button held down.

[clever spade]

Sorry, I'm not familiar with Cinemachine

[gilded schooner]

Like the Mario jump

[brisk reef]

oh

[brisk reef]

I think blackthornprod made a perfect guide on that

[gilded schooner]

send me the link if you can find it.

[brisk reef]

Imagine jumping like a jetpack

the longer you hold it down, the more your height off the ground increases

[runic cloud]

is it possible for one internet tab with Unity to read what's going on in another tab with Unity?

[leaden ice]

at that point it's really a javascript/web development question

something like https://dev.to/dcodeyt/send-data-between-tabs-with-javascript-2oa for example

[digital whale]

I'm trying to add sound to this flappy bird clone I made with GMTK's tutorial.I don't understand how to get the sound to work though.

[somber nacelle]

what isn't working about this?

[digital whale]

It keeps saying "ArgumentNullException: Value cannot be null".I gave the bird game object an audio source component and I included the right mp3 to use for the audio clip.

[somber nacelle]

sounds like the audio clip isn't assigned to the audio source

[digital whale]

Are you sure?

[leaden ice]

this screenshot doesn't mean much

show what sfx_wing is assigned to in your script instance

[somber nacelle]

Debug.Assert(sfx_wing.clip != null, "The clip is null", sfx_wing.gameObject);
throw this one line above the .Play() call and it will yell at you when the clip isn't null and you can even click the error to highlight the gameObject where it is null

[digital whale]

Okay,so I see now that the reference needs to be assigned.So how do i assign the clip to the reference?

[leaden ice]

you don't

you assign the audio source

[digital whale]

So how do i assign the audio source?

[somber nacelle]

drag the audio source that has the clip assigned into the slot in the inspector for this script

[digital whale]

Oh.I guess I forgot your supposed to do that.

Okay thank you

[somber nacelle]

so just to confirm, it was actually the sfx_wing variable that was null and not the AudioClip assigned to the AudioSource?

[digital whale]

it was the variable

[somber nacelle]

yeah i really dislike that the Play method can be called on a null object and not throw an NRE but instead throws an ArgumentNullException

[devout solstice]

How could I get the button that is clicked through a addlistener? The button is in a list and I have a for statement putting the addlistener on each button

[leaden ice]

foreach (var button in myList) {
  var theButton = button;
  button.AddListener(() => SomeFunction(theButton));
}```

or whatever other parameter you want to add

[lilac zenith]

    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody>();    
    }

    public void EnableKinematic()
    {
        rb.isKinematic = true;
    }```

I am trying to access the rigidbody of not the gameobject that I have the script attached to but the object that I have attached the script manager to. This is turning off the isKinematic for the script manager

Any ideas? Let me know if more context is needed.

[devout solstice]

GameObject.FindObjectOfType<scriptmanager>().gameObject

[leaden ice]

GetComponent<Rigidbody>(); this gets the RB of the GameObject your script is attached to

the simplest way to get some other one is just to drag and drop it in the inspector instead of assigning it in your code.

[lilac zenith]

Yeah, I thought about that but the issue is there is an .fbx with about 60 different parts so I would have to go and do that for each. I was wanting to find a way that would scale. But if that is the best way then I can do it

[lilac zenith]

Would this not be getting the script managers gameobject?

[devout solstice]

Thats what you said right?

[leaden ice]

what exactly are you trying to do?

I don't understand

is this for a ragdoll?

[lilac zenith]

No, sorry. I did a poor job explaining. I have the script attached to the script manager (GameObject1) and then am needing to access a function in the "On Release Hand" of a seperate game object (GameObject2). I am needing to turn off the kinematics for the GameObject2 but since the script is attached to Gameobject1 then it is turning the kinematics off for the script manager (gameobject1)

[leaden ice]

ok so what was all that about "60 different parts"

you're only mentioning two objects here

[lilac zenith]

I am needing to do that for all 60 parts

[leaden ice]

for this you just directly reference it:

public MyOtherScript theInstance;
void DoSomething() {
  theInstance.SomeFunctionOnMyOtherScript();
}```

[leaden ice]

You can use GetComponentsInChildren<Whatever>

and loop over them all

[snow geode]

using UnityEngine;

public class FollowCursor: MonoBehaviour
{
void Update()
    {
        // Get the mouse position in screen space
        Vector3 mousePosition = Input.mousePosition;

        // Convert the mouse position to world space
    Vector3 worldMousePosition = Camera.main.ScreenToWorldPoint(mousePosition);

        // Get the direction from the player to the mouse
        Vector2 direction = (worldMousePosition - transform.position).normalized;

        // Get the angle of the direction in degrees
        float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;

        // Rotate the player to face the mouse
        transform.rotation = Quaternion.Euler(0, 0, angle);
    }
}
```  When I start the game the player's rotation is set to the left, is there a way to make it start towards the cursor so the player rotation is not offset?

[lilac zenith]

Preferably I would like to just mention the specific game object that I am holding. Although I do think that would be a solution that would work

[leaden ice]

now I'm back to not understanding

are you going to be "holding" one of the 60 parts?

[lilac zenith]

yes, there are esesntially 60 gameobject2's

[leaden ice]

Just have a Rigidbody currentlyHolding; reference

have it always refer to whatever you're currently holding

and just do what you need through that variable.

[lilac zenith]

okay, I will give that a try. Thanks everyone.

[plush grove]

I'm writing (rewriting) a mod for a Unity game. I created a Basic UI that has a few buttons/text inputs that sit under a Canvas within the editor. I moved the Canvas into assets and created an asset bundle for the Canvas. Within the mod when I load/Instantiate the canvas I see it, and all of the elements under it. However I can not interact with anything. Attempting to find child components returns null. How would I get access to the inner buttons/inputs (During runtime only because I am not actually doing any building in Unity Editor, just using it to create the asset bundle)

Or am I better off sticking with IMGUI

[soft shard]

Im trying to restructure my character controller, the way it works now is I have a parent with a bunch of scripts that reference various parts of nested child objects (specifically the rigidbody, collider, various skinned meshes and specific bones from a rig hierarchy), the problem is I have different characters that have different rigs/skinned meshes, what might be a good way to have the parent (or some other system maybe?) link the references from x character prefabs? Atm im thinking I could give the parent a ScriptableObject and setup the references on each character there (then pass the SO to the parent when im spawning x character), but I feel as characters become more complex, that approach may get more unorganized, is there another way I could approach this problem, or does this sound normal?

[leaden ice]

However I can not interact with anything
Missing EventSystem or GraphicRaycaster perhaps?
Attempting to find child components returns null
Show what you attempted?

[shut scaffold]

so im trying to make an interaction event on the inspector tht i can add it looks like its trying to work but it doesnt pop up

[leaden ice]

looks like the selection is filtering to Texture2Ds, but then you're checking if they're sprites?

[left adder]

Is 2D Unity Navmesh strong?
Or is it recommended to wright my own pathfinding algorithm ?

[next seal]

oh, which one is the correct one ?

[rain minnow]

I'd go the SO route first, simple to implement. Any change to references happen on that one asset tied to the prefab . . .

[leaden ice]

you tell me?

I have no idea what you're doing

Looks like Sprite maybe?

[next seal]

Well I don't know in unity waht I have selected says texture type sprite 2d and ui

but idk what the difference between texture and sprite is

[leaden ice]

suffice it to say they're different for now

so you can't say "give me a bunch of Texture2D" and then say "if any of these things are not SPrites, throw an error"

of course an error will be thrown

why not just filter to Sprite?

[next seal]

because in line 16 it takes in textures and thats someone elses code to manually set pivots for each sprite in a spritesheet

and for sommmmeee reason it takes in texture

which i dont understand

[plush grove]

I was under the impression I can't use the Editor's event system because I cannot include the script inside the asset bundle.

[leaden ice]

I would ask the person who wrote the code

[leaden ice]

if you don't have EventSystem in the scene, naturally UI will not work

not sure what you mean by "Editor's event system"

[plush grove]

I'm not building a game - I'm adding a mod to the game

[leaden ice]

I know that

[orchid bane]

Is there a way to invoke an event in my coroutine if the coroutine was stopped?

[soft shard]

Fair enough, just wondering if there was a more elegant approach, but your right it would only be one point of change, so ill stick with this until it causes problems - thanks for the response

[leaden ice]

coroutines that were stopped are not running. They can't do anything

[orchid bane]

I'd like to know if my coroutine was stopped tho👀

[leaden ice]

I'm assuming you're doing VRChat

https://docs.vrchat.com/docs/whitelisted-world-components
EventSystem is specifically whitelisted

[next seal]

would you say in order to edit a spritesheet that would require accessing a texture or a sprite though

because maybe i can just change it

[leaden ice]

fire an event when you stop the coroutine

[soft shard]

Is your coroutine public? What can be allowed to stop/access it directly? Or is it only stopped if the object is SetActive(false) or yourScript.enabled = false from some other script?

[orchid bane]

Character's death stops all coroutines on the character

[leaden ice]

Just fire the event in the Die() function

[plush grove]

I am not - its a mod for PlateUp. You got the buttons works -> I moved my Canvas and an Event System into an empty GameObject and added that gameobject as the only asset in the bundle - now everything loads and is clickable. I suspect I'll now have to loop through that parent game object to assign the proper listeners

[leaden ice]

i don't know much about spritesheets

[next seal]

oh well I will try around im sure that i can find it out, not like there is many options :D

thank you for your assistance

[weak nacelle]

Guys, I have an interesting conundrum here that I need a little help understanding

        Debug.Log("Incoming damage is spell:" + incomingDamageTable.spell);
        Debug.Log("Incoming damage is player:" + (incomingDamageTable.player != null));

        if (incomingDamageTable.player != null && !incomingDamageTable.heal)
        {
            if (incomingDamageTable.spell)
            {
                if (damageTable.Count == 0)
                    damageTable.Add(incomingDamageTable);
                                 Debug.Log(damageTable[0].spell);
                        }
                }

So how can the initial 2 debugs return true

while the final debug return false

[modern creek]

How do I remap .unitypackage files back to Unity? For some reason WinRAR captured that file extension, and when I open with (what appears to be) the unity exe, it tries to open unity hub.

[weak nacelle]

When by all means the final debug should echo the first debug since it should just be a duplicate of the first

[somber nacelle]

that's not a code question let alone a unity question. search "clear default app" for your operating system

[modern creek]

I mean, it's a unity question, that's sort of nitpicky.. but.. the point is that the default app is currently unity.exe, but unity hub is opening, not unity.exe

[weak nacelle]

Does adding an entry to a list change its values somehow?

[modern creek]

no

[weak nacelle]

In this case it must be though as there is no other way for this behaviour to occur?

[modern creek]

https://forum.unity.com/threads/windows-doesnt-know-how-to-open-unity-or-unitypackage-files.654871/ found a solution, weird

[modern creek]

Are you familiar with "by reference" and "by value"? putting elements into a list won't copy it - so if you're changing the elements elsewhere, they'll be changed inside your list

Post the code, though, the problem might not be what you think

[weak nacelle]

I already posted the code directly above

[modern creek]

your indentation is making this hard to understand - you do see that, yeah? that the Debug.Log under the if statement isn't inside the if clause?

[quaint rock]

first i would clean up that code

[modern creek]

(also just FYI you generally should embed your values in strings using the interpolation operator $, it'll make it a lot easier to read)

[quaint rock]

you are also missing a brace, so the final debug will not be conditional on the if (damageTable.Count == 0) statement

[modern creek]

Debug.Log($"Incoming damage from spell is {incomingDamageTable.spell}");

[weak nacelle]

Its not supposed to be conditional on the if statement

[quaint rock]

would have tricked me with the indentation that was showing a different intent then what the code was doing

[modern creek]

You haven't really posted enough code to understand the problem, though - you asked how the first two lines could both print true but you didn't show us how you're assigning those values...

[quaint rock]

so is the 3rd debug printing?

[weak nacelle]

Yes

but it is the exact same value as the initial debug

just after being added to the list

[quaint rock]

that would be expected with the code you show

[weak nacelle]

Except its not

Its false when the first debug is true

[quaint rock]

you are printing the incoming spell, then adding it to a list then printing the first element of the lists spell which is the same element

[weak nacelle]

Yes

But it is printing false instead of true

[modern creek]

        Debug.Log($"Spell: {incomingDamageTable.spell)}";
        Debug.Log($"Player: {incomingDamageTable.player != null}");

        if (incomingDamageTable.player != null 
            && !incomingDamageTable.heal // heal? or spell?
            && incomingDamageTable.spell
            && damageTable.Count == 0) damageTable.Add(incomingDamageTable);

is that what you mean?

[weak nacelle]

and then after that you would type Debug.Log(damagetable[0].spell) and it would be false despite the initial debug being true

It doesnt retain its value and I don't get why

[modern creek]

I mean, you're adding something to a list but you're assuming that damageTable[0] is the item? if there's anything else in the list, you're looking at the wrong item. Items are added to the end of lists, not the beginning

[weak nacelle]

There is nothing else in the list if not damageTable.Count would not be equal to zero

[quaint rock]

well you still print it no matter the length

[modern creek]

but you aren't debug.logging if count = 0

[quaint rock]

you just only add if 0

[weak nacelle]

Yes but I can check in the inspector and see that there is nothing in the list

[modern creek]

you're debug.logging it all the time because your indentation is wrong

[weak nacelle]

I am supposed to debug.log it

all the time

[quaint rock]

would strip it down to the most simple case and test your assumptions

[modern creek]

you don't really understand.. lemme rewrite your code

        Debug.Log("Incoming damage is spell:" + incomingDamageTable.spell);
        Debug.Log("Incoming damage is player:" + (incomingDamageTable.player != null));

        if (incomingDamageTable.player != null && !incomingDamageTable.heal)
        {
            if (incomingDamageTable.spell)
            {
                if (damageTable.Count == 0)
                {
                    damageTable.Add(incomingDamageTable);
                }
                Debug.Log(damageTable[0].spell); // this is printed even if the damagetable.count is 0.. in fact, it's always printed! because you add to the table BEFORE printing this anyway, and might not even refer to the thing you just added

            }
        }

i haven't changed your code aside from fixing your indentation and adding brackets to highlight that what your code is doing - the code as i wrote it is identical to yours, but it should be obvious now why the debug.log in the block isn't doing what you expect it to be doing

[weak nacelle]

It will always refer to the thing I added because I am testing this once

[modern creek]

Also just FWIW your variable names make it really hard to decipher your intent. Booleans should have "is" or "did" or "does" or "can" before them so they just read like english. Like.. isTargetAPlayer or isHealingSpell

[karmic bloom]

Not sure if this is even possible or not, is there a way for me to take this code:

    public AudioClip GetClipByName(string clipName)
    {
        foreach(var clip in _clips)
        {
            if(clip.name == clipName)
            {
                return clip.clip;
            }
        }
        return null;
    }

And not only return a clipName but also force it to play through a specific audio source?

[modern creek]

(otherwise you ought to paste enough code so we can see what .spell and .player and .heal and damageTable actually are

[modern creek]

Yes - is the audio source linked in that monobehaviour?

[karmic bloom]

It's not at the moment, I'm just now getting started. This is a tool I'm making

I can put it there however

[modern creek]

        public void PlayClip(AudioClipType type)
        {
            AudioClip c = AudioDatabase.GetClip(type);
            if (c == null)
            {
                w($"No audio clip found for {type}.");
                return;
            }
            _sfxSource.PlayOneShot(c);
        }

something like this

and GetClip is:

just maps enums to audio clips, but you have the right idea

just get the clip, and pass it to PlayOneShot()

looping over your clips each and every time looking for a string comparison is probably going to be a bad idea, but you'll find that out later 🙂

[karmic bloom]

Well the reason why is because I'm doing this in the tool:

[modern creek]

Sure, that's fine

and the audio manager is in your scene? make sure it's got an audio source and you're good

[karmic bloom]

Yeah it's in the scene.

I would like to not have to hardcode the audio source either, but I'm assuming looking for the clip and the source will eventually get to be a lot?

[modern creek]

clean up your code, too, maybe:

public void PlayClip(string clipName)
{
  AudioClip clip = _clips.Find(x => clipName);
  if (clip == null) return;
  _audioSource.PlayOneShot(clip);
}

What do you mean by hardcode the source?

Just declare it and link it in the inspector

Or if you're making audiomanagers elsewhere in your game and don't want to forget that step, in your OnEnable() make a GetComponentInChildren<AudioSource>() and have it throw an error if it can't find one

(the name audiomanager to me, though, implied a singleton, so you'd only need to do that once, ever, then forget about it)

[karmic bloom]

Yeah I think I'm overthinking what I'm trying to do lol

[karmic bloom]

Yes it will be there always

[modern creek]

I'd personally use scriptable objects for something like this, but if that's foreign to you, don't worry about it too much, it's not really required

Then yeah, you're golden.. if you want I'll even show you the entire source code for my audio singleton

does music, sfx, etc, but isn't too complex

https://pastebin.com/2QfFkELi

the only thing AudioDatabase is doing (in mine) that you'd need to do on your own is finding the clip you want to play based on a string

(mine uses enums but that's nbd - you can use strings)

[karmic bloom]

It's not foreign, it's kinda hard to explain what I'm doing really. I just didn't want have the player create a scriptable object for every audio clip or am I overthinking it?

[modern creek]

players don't create scriptable objects.. you do

[karmic bloom]

Well

[modern creek]

Think of a scriptable object as a uh.. data file

[karmic bloom]

I don't mean the player

lol

I mean the game dev sorry

[modern creek]

OK, so.. they don't create an SO for every audio file, they create one for "all" of them, typically

mine look like this:

the SO is sort of .. where you link the files to the enums - then anywhere in the app, you just ask the SO for the clip you want

That way you don't have to .. link the clips you need to every audio source through your entire app

But if you're using an AudioManager singleton that you plan to have everywhere in your app, and you don't have any need to have multiple listeners or audio sources, then you're fine

[karmic bloom]

Yeah. I do want multiple sources though, for the different settings.

[quaint rock]

well at the call site what do you want it to look like. you provide a source and clip, or just a clip and it knows the source based on it?

[karmic bloom]

Yeah I'm trying that now

I just added it

[weak nacelle]

I found the problem and it was unrelated to the code I pasted since it was a bastardized version of the actual code which would probably give you brain damage. Thanks for the advice and putting up with my stupidity anyhow

[modern creek]

You probably don't want multiple sources but rather multiple listeners? What do you mean, different settings?

There should only be one listener (acutally I think there can only be one listener?) - if you have settings like volume/position/etc, you change those values on that listener.

[quaint rock]

no he means mulitple sources, with differnet settings each

[karmic bloom]

No I want multiple sources

SFX, UI, Game, Master, etc

[modern creek]

OK, that's fine.. what do you mean with different settings then?

[quaint rock]

really would just have multiple lists of clips, one for each source

[modern creek]

ok, so, no problem... i'd still route all of those through your audiomanager from what I understand

[quaint rock]

so when you play a clip it figures out which list its from and plays with the associated source

[modern creek]

Hmm.. maybe, but maybe not depending on if master should intercept that

[karmic bloom]

yeah I'm trying to figure it out now. I think I have to link it through the PropertyDrawer or it won't properly pick it up

Since I'm using a custom GUI

[modern creek]

I'd probably but the master settings on the listener but then have all of the sources play at different volumes

[karmic bloom]

That's how I have it

Master is at the top then all others derive from it, but can be changed individually

[next crescent]

Is it possible to create a shortcut in unity at runtime? Say, invoking a function when certain keys are pressed and held in a specific order

[soft shard]

If the order is important, you could probably store your keypresses in an array or stack - otherwise if you just want to know if certain keys are currently held down, you could check for them in Update, if your using the "new" input system, you could subscribe events to an action map, or check the "wasPressedThisFrame" or "IsPressed" of the "current" Keyboard, assuming this is only important for the keyboard

[next crescent]

Great, thanks

[rain minnow]

this is fine. you can create a source for each type of sound and route them through a corresponding mixer which all ties into the master mixer . . .

[frigid anvil]

Do Joints work for you? Something like https://docs.unity3d.com/ScriptReference/FixedJoint.html ?

[swift falcon]

yeah I didnt realize spring joints were a thing. Seems like its working, thanks!

[plush grove]

Will transform.GetComponentInChildren<T> return all of the type in all of the children or only in the first child it encounters them?

[frigid anvil]

Insert an 's'.

[junior aurora]

So I have a Object(A) that is moving diagonally, I have 2 child object(B & C) on A.

A is being tweened to move diagonally.
B & C are getting a RigidBody2D added to them so that they can move away from each other with physics by adding an inpulse force to them.

B gets a force at Vector2(1,1)
B gets a force at Vector2(1,-1)

However, they are not moving in different directions at all. They stay as one.
How does rigidbody2d work when it is on a child? and the parent is constantly moving through tweening?

[plush grove]

🤦

[leaden ice]

Why would you need a custom inspector for that?

[swift falcon]

#💻┃code-beginner message Anyone got ideas

[nimble dome]

Im trying to access ParticleSystem.VelocityOverTime and the parameters for orbital and offset are available but linear doesn't appear to be. Is there another way to change it or is it not accessable from script?

[leaden ice]

In the inspector?
#↕️┃editor-extensions

[warm wren]

Cant you do something like if(Attacking) {bot.SetDestination(bot.transform);} //sets destination to itself so it stops moving. Else {Do the destination finding stuff here}

[swift falcon]

Lets try

[frigid anvil]

To a certain extent you could do that, but it's a simplification of a larger pattern, the state machine. Your object is in patrol (or destination-finding, but I'll simplify it to just 'patrol') mode, until it is attacked or finds the enemy, at which point it switches out of the patrol mode into attack mode, until the enemy (or itself) is dead, at which point it probably switches back into patrol. You can special case this, and it'll work pretty straightforwardly, but if you have more states, or substates, the code gets very complicated very quickly.

In any case, if you're using Nav Agents, there are other simple ways to stop navigating, IIRC.

[warm wren]

Yeah I guess u could set it's speed to 0 or i think use NavMeshAgent.isStopped to stop navigation

[frigid anvil]

So I use A* Pathfinding, in general, and so it has an 'AIPath' object that gets associated with the object that moves, and I set 'canSearch' to false, and it stops looking for the next step to take. I...really should explore the basic nav mesh agents again, and see what they offer, but I vaguely recall a similar operation available on it. Essentially turning off nav mesh movement for a while.

[frigid anvil]

That said, I also use Behavior Designer, which is killer for just this kind of thing.

[swift falcon]

Oh my god I forgot to respond sorry. But yes that does work

@frigid anvil @warm wren Thanks

[swift falcon]

Might try this to

That also works

[indigo drift]

I don’t know what I’m doing
I want to be able to use different methods from this state here, so I made an action that I can change for every state
That is not working
How do I do something like this

I can’t assign any methods to it. Or at least i don’t know how

[cosmic rain]

How are you assigning the methods?

[leaden ice]

You mean from code or from the inspector?

[indigo drift]

I don’t know how. Since it doesn’t appear in the inspector but I don’t know how I’d do it through code

[leaden ice]

Which do you want to do

Inspector or code

[indigo drift]

Inspector preferably?

[leaden ice]

UnityEvent is what you need then

Not Action

[indigo drift]

When I used unity event I couldn’t find the methods either

[cosmic rain]

But it doesn't make sense if it's for runtime states though...🤔

[leaden ice]

Find what methods

[cosmic rain]

They need to be public.

[indigo drift]

When I go to assign the methods in the inspector with a unity event, it’s just a bunch of random scripts, I can’t find anything from the state

[leaden ice]

Wdym random scripts

What are you looking at

[leaden ice]

You need to drag an object into the slot

Not a script

A ScriptableObject or GameObject

[cosmic rain]

You need to reference the object which methods you want to reference.

So in your case it needs to be an instance of TextStates

[leaden ice]

(e.g. itself)

[indigo drift]

But this is a scriptable object, you can’t put that in the scene? It needs to be a monobehavior

[leaden ice]

Why are you talking about scenes

[leaden ice]

We're talking about the slot in the inspector here

[cosmic rain]

Unity Object instances exist not only in the scenes. SO instances and components on prefab GOs are all instances too.

[leaden ice]

No

That's the script

Wrong thing

Drag in the very asset whose inspector you're looking at

[indigo drift]

Oh shit ☠️

[cosmic rain]

Script asset is not an instance of the class that is written in it. It's just an instance of a text/script asset type(not sure what type exactly).

[indigo drift]

Okay you were right it worked

Thas crazy

[tawny jewel]

hey, for some reason my gameobject with rigid body and a collider wont collide with my other gameobject with collider, any idea why? (specifically it does detect oncollisonenter, but it wont lie down on the collider, it passes thorugh it instead)

[leaden ice]

sounds like you're moving the object in a way that doesn't respect collisions

[tawny jewel]

im moving it with transform, position, should i move it with rigidbody.moveposition instead?

i had some problems with it

[leaden ice]

Moving with the Transform ignores physics

You need to move it via the Rigidbody, yes

MovePosition isn't really the way though no

you'd move it via setting velocity and/or adding forces

[tawny jewel]

yea i heard it doest work well with other bodies types than kinematic

[tawny jewel]

could you give an example of code?

[autumn cipher]

moveposition should be used when the rigidbody is kinematic

[leaden ice]

rb.velocity = something;

[tawny jewel]

ah alright, ill try that, thanks

[warm wren]

ask chatgpt

I'm jk lol

[tawny jewel]

bruh lmao

on the other hand though i might try it you have no idea how much issues is my powerup system generating

[autumn cipher]

public static bool RayCastOnceNonAlloc(Vector3 origin, Vector3 direction, RaycastHit hit, float maxDistance, LayerMask layermask, QueryTriggerInteraction querry = QueryTriggerInteraction.UseGlobal)
    {
        RaycastHit[] temp = new RaycastHit[1]
            { hit };

        int hitCount = Physics.RaycastNonAlloc(origin, direction, temp, maxDistance, layermask, querry);
        return hitCount > 0;
    }```
would you think this is better than the regular raycast method?

in terms of performance and garbage generation

[boreal bone]

Are you asking if this is better than RaycastNonAlloc?

[autumn cipher]

No compared to regular raycast

the bool one

[boreal bone]

I think it would be the same speed

because the whole point of the NonAlloc method is to avoid having to generate garbage

but since you created a RaycastHit[] temp = new RaycastHit[1], it gets destroyed immediately after the function returns

[leaden solstice]

You need to reuse your buffer to get benefit from it

[autumn cipher]

perhaps I should use ref/out keywords for RaycastHit?

[leaden solstice]

And your code won't have the same result as regular Raycast when there is more than one hit

[autumn cipher]

yeah I'm trying to make it single hit just like the regular raycast

also, what?

[leaden solstice]

No. That's not how RaycastNonAlloc works.

When a full buffer is returned it is not guaranteed that the results are the closest hits and the length of the buffer is returned.

[leaden solstice]

Are you using ChatGPT?

[autumn cipher]

no, I wrote the code myself, I told gpt to optimize it

and it told me to get rid of the optional parameter for performance

like what

[autumn cipher]

I know RaycastNonAlloc returns an array of hits just like RaycastAll, I'm trying to replace the regular (bool)Physics.Raycast() method by using the nonalloc method

[leaden solstice]

Physics.Raycast is already non alloc and their behaviour is not same as I quoted

[tawny jewel]

quick question- what did i mess up? the bullet is chilling where it was spawned

    {
        bulletRB.velocity = Vector2.right * bulletspeed;
    }```

[autumn cipher]

oh I didn't know that, thanks

[tough aurora]

do raycasts detect hits if the raycast is inside of an object?

[leaden solstice]

No

[tough aurora]

is there any solution? because im tryna detect whether the player is touching air or the floor

[autumn cipher]

are you using a rigidbody or a character controller?

[leaden solstice]

Make it not start from inside of object you trying to check?

[tough aurora]

using a script without physics

with a rigidbody

[autumn cipher]

but rigidbody is a physics element

did you mean a collider with no rigibody?

[tough aurora]

im trying to detect if the player hops off a platform

i've tried using colliders

but it doesnt really work

[autumn cipher]

if you're using a rigidbody or character controller, you don't need a raycast for ground checks

[tough aurora]

i dont use gravity

[indigo drift]

` public UnityEvent<ChatMain> changeText;

public void doSomething(ChatMain chat)
{
    Debug.Log("a");
    chat.textSpeed = 0.01f;
} ` `

Sorry sent early

[autumn cipher]

rigidbodies have their on various collision check events, best to use them when ground checking

[tawny jewel]

.

[tough aurora]

i've used them, but is there a specific way to detect if the player is colliding with nothing

[indigo drift]

I'm getting an error that says "Object of type UnityEngine.Object cannot be converted to type ChatMain

What could be the problem? This is how I invoke it
textState.changeText?.Invoke(this);

this line is on ChatMain itself

[autumn cipher]

bool isTouching = false;
    private void OnCollisionEnter(Collision collision)
    {
        isTouching = true;
    }
    private void OnCollisionExit(Collision collision)
    {
        isTouching = false;
    }

[tough aurora]

i have used them

they're currently what im using

but with triggers version

[autumn cipher]

triggers are for triggers, why are you even using them?

your ground won't be a trigger

[tough aurora]

im not using gravity

i guess ill try colliding then

[autumn cipher]

so your player floats around like an astronaut?

[tough aurora]

yeah

but it looks like its hopping from platform to platform

[autumn cipher]

lol okay but these should still work regardless of gravity

[tough aurora]

should i make the collider extend or just cover the 3d model?

[indigo drift]

I’m still having trouble with this :,) casting did not work either

[karmic bloom]

Anybody here know where there is any documentation for changing the output device? I'm trying to allow the player to change where they hear their audio (headphones, speakers, etc). I can't seem to find any documentation though

[vague tundra]

I have a field in the parent class that I want to modify/re-declare in the child class. How can I achieve this?

[cosmic rain]

I'd assume that it's something controlled by the os. Unity can only use whatever the OS gives it.

[main shuttle]

AFAIK just like with monitors, the Operating System is responsible for that.
You could fix it with C# itself, marshalling the Operating Systems dll's to change it. But take this with a grain of salt, I'm not 100% sure about this either.

[cosmic rain]

You could try using the new keyword in the field declaration.

[karmic bloom]

Gotcha. i've just seen unity games that have options in the settings menu for mic, headphones, etc. figured I'd give it a shot

[main shuttle]

Yeah I would assume they do it this way. Also, some of the assets on the asset store give you this functionality, if you want to throw money against the problem.

[karmic bloom]

Nah it's something I'd want to try myself if I did it. Thanks though

[vague tundra]

Doing that seems to leave me with 2 copys of my field in the inspector.
I now have a new question. The field in the parent is marked virtual and the field in the child is marked override.
However I am getting an error, and I suspect it's related to the field being an enum. Is this a common problem?

[cosmic rain]

You can't override fields or make them virtual.

Maybe use an interface property instead and define the field separately in each class.

[vague tundra]

Can you make virtual properties and then override those?

specifically enums

[west lotus]

Why do you need this ?

[vague tundra]

All class B's inherit from class A. All class A's have a field declared and assigned.
B's need that same field but with a different value.
C's also inherit from A, also needing the field, but don't need it changed.

My field is an enum

[west lotus]

But putting a different value isnt overriding the prop. Just set the value you need in a init method, or start or whatever

[vague tundra]

I need the field settable in the inspector

[west lotus]

That would also just work

[vague tundra]

With which implementation?

[west lotus]

The value would be stored in each instance its not tied to the parent class at all

[cosmic rain]

You jest set the value in the inspector.🤷‍♂️

[west lotus]

If you have a serializable public enum in A you can set it to what ever value you want in a instance of B

[vague tundra]

Ahh, yes of course. Thank you(: Silly me

Is it good practice to create interfaces in their own file, like classes?

[cosmic rain]

Neither bad nor good.
I'd say if the interface takes some space and there's already a lot of code in the file, move it to a different file.

In fact I'd move them to a new file in any case.

[sour trench]

I find myself constantly being screwed over by needing icons for things which require me to more often than not create SOs or expose it somehow to the editor just to provide it. In this case I would really just like to define status effects in the code and not have to create assets for each one, but I don't know how to provide the icon then. I've been thinking about creating a global manager that have a bunch of icon properties for icons that are shared across multiple things, such as abilities and status effects for example. However, I feel like this could grow out of control quite quickly and bloat the memory usage since you'd have icons loaded in that aren't used at a particular point in time. I've also tried loading icons from the code from a specific folder using Resources.Load but I found that it's not very reliable since paths and name of icons can change without the code knowing about it.

Do you guys have any alternative suggestions for how I could approach this problem?

public class StatusEffect : ScriptableObject
{
    public string statusEffectName; // "name" is already taken by ScriptableObject
    public string description;
    public Sprite icon;

    public virtual void ApplyEffect(BaseController caster, BaseController target) {}
}

[CreateAssetMenu(fileName = "New Bleeding Status Effect", menuName = "Data/Status Effects/Bleeding")]
public class BleedingStatusEffect : StatusEffect
{
    public override void ApplyEffect(BaseController caster, BaseController target) {}
}

[thin aurora]

Yes, it is.

Every file only consists of 1 thing - class, interface, enum, whatever

And the name of the file respresents what that thing is.

The only exception I would name is a simple record type for some obscure behaviour never used again, or File type classes. But neither of those are possible in Unity as far as I know.

It's just way easier in terms of readability, knowing the file's purpose without having to look into it for anything extra. If you have to consider moving it because it might become bigger than what you would accept for some reason, you might as well just put it in that new file.

[vague tundra]

Awesome, thanks!(:

[void basalt]

Is there any way to access the hardware intrinsic leading zero counter inside unity?

All of the ones on the docs require a later runtime version

[thin aurora]

Do it in a json file maybe

Except stuff like applying the effect can't really be done in it because it's specific scriptable behaviour

The thing with these type of things is scalability, and it is probably a very good idea to just create a seperate file for them should you add more behaviour to it. It's gonna be a lot better than one bloated manager

[sour trench]

@thin aurora You mean like I have already done in my example?

[thin aurora]

Yes

[vague tundra]

My UI sprites for the individual inventory slots appear nicely in the bottom right, but the same-sized UI objects in the top left appear squished, as if their 9-slicing isn't working or something. Any thoughts?

[rough brook]

so a tutorial I am following says this

I have written this. only i have an error over this line and they dont in the video

[main shuttle]

This is #💻┃code-beginner stuff, and can you show the actual error?

[rough brook]

I think I understand what its saying but im confused why it works for him and not me

[main shuttle]

He made a script named HealthBar before this. This just makes a reference to that script. You currently don't have a HealthBar script, or you named it differently.

[rough brook]

I cant because of the error

[thin aurora]

That's not related

[thin aurora]

Your class is not called HealthBar then

[rough brook]

now I want to guess its because this script is under a different namespace to the other one?

[vague tundra]

@rough brook Show code inside HealthBar.cs

[rough brook]

health is in RPG.Combat . HealthBar is in RPG.UI

[vague tundra]

Oh, yes. Likely a namespacing issue then

[thin aurora]

You have it in a namespace

Add using RPG.ui; at the top of the other file

If your IDE is set up correctly you can also press ctrl + . on HealthBar and it should give you the suggestion to add it

If it doesn't do that you need to configure your IDE properly

[rough brook]

now I got this. not sure what it means by protection level

[thin aurora]

Your method is most likely private as it has no access modifier before it

Put public before it

Accessibility modifiers is something you should look into

And maybe continue your questions in #💻┃code-beginner

[vague tundra]

I hate to say it, but its likely you've followed a tutorial that may have been slightly too advanced. If you feel too lost following the tutorial, I'd recommend learning some C# basics before tackling the tutorial(:

[rough brook]

thanks for the help guys. got it working.

[rough brook]

wouldnt believe I have been doing this for more than a year on a college course lol

[main shuttle]

#💻┃unity-talk is the catch all channel when the question doesn't belong in the specific channels. No idea about your SSD though, you can just do a hardware check.

[devout solstice]

How could i get which button was pressed from a addlistener when the button is in a list of other buttons

[thin aurora]

Add a tag, unique name or spot in your gameobject hierarchy

Not sure if you can compare the reference, but considering it's done by checking memory (I think?), you could also use a First/Single(OrDefault) on your list

[devout solstice]

I was tryna a avoid tags but aight

How do I give a father to an object through code?

[main shuttle]

You mean a parent? Then .parent = something

Also, don't cross post

From the #854851968446365696

[forest vigil]

ok thanks

yeah parent sounds better anyway i saw somebody else call it father so i went with that

[main shuttle]

father doesn't really exist in coding, at least I have never heard of it in 20 years.

Its always parent -> child relations

[forest vigil]

yea same lol

[rough brook]

I dont have a problem but I do have a question. my tutor had us learning atan2 for rotation towards an object. Why did learn that if LookAt makes it so simple?

[vast seal]

thx, i'll copy paste it there 👍

[plush grove]

Whenever I use InputSystem.DisableDevice(Mouse.current); the mouse pointer disappears, I can set it visible and it comes back for a period of time but will disappear again eventually. Is that expected behavior? I can still interact with elements in my UI wherever the mouse pointer is even when not visible

[cosmic rain]

It makes better code. Same as any variable, you can pass them around

They are also often used for events

[thin aurora]

Storing method references in a list for example

Events

Stuff that references a method without invoking it

[cosmic rain]

You can subscribe to a delegate from different places and receive events via them. This way you reverse the dependencies and don't need to invoke methods manually.

[mental rover]

atan2 (arctangent with 2 arguments) is lower level and may let you connect what is actually happening mathematically which can be helpful for a better understanding in general, for use in other engines, etc
transform.LookAt is a simple wrapper method to make things in Unity specifically a bit easier

[unreal temple]

You can use them for callbacks. For example you could have a function like this:

IEnumerator MoveCoroutine(Vector3 to, Action onComplete) {
  while (transform.position != to) {
    transform.position = Vector3.MoveTowards(
      transform.position,
      to,
      speed * Time.deltaTime
    );
    yield return null;
  }
  onComplete();
}

void MoveAndShoot(Vector3 to) {
  StartCoroutine(MoveCoroutine(to, Shoot));
}

void MoveAndSpeak(Vector3 to) {
  StartCoroutine(MoveCoroutine(to, () => Say("hello!")));
}

oops, i left out the invocation lol

fixed now

[rough brook]

I wish I knew about it first. Really confused why I wasnt taught something that simple before moving on to atan which seams more complex

[unreal temple]

Ask your teacher why

[rough brook]

waiting for a reply

[mental rover]

depends on your level and background really - I'd be pretty wary of a course that felt teaching me a specific method for a specific version of a specific engine was a worthy thing over a fundamental concept in programming/mathematics that would be applicable anywhere

[unreal temple]

Maybe they taught you atan first hoping that you'd discover LookAt on your own

[rough brook]

who knows but pretty annoyed considering it wasnt revealed even as I was clearly struggling

is what it is. I have come out the situation knowing

[mental rover]

I'm sure you can appreciate that the easiest way to do something, that obfuscates/hides the detail, isn't necessarily in line with helping you have the best understanding and coming away with the best education though

sometimes it makes sense if the simple thing is a building block towards the harder thing, but sometimes it can actually be the opposite and make it harder

[rough brook]

sure but if I dont understand the simple, its strange to learn the complex, I would think

[unreal temple]

That velocity calculation is unreadable!

var speed = (isCrouching, isZooming) switch {
  (true, _) => crourchWalkSpeed,
  (_, true) => zoomWalkSpeed,
  _ => walkSpeed
}
var velocity = new Vector3(
  currentDir.x * speed,
  velocityY,
  currentDir.y
);
characterController.Move(transform.TransformDirection(velocity) * Time.deltaTime);

Longer but at least it makes sense

[rough brook]

my tutors response was that trigonometry and pythagoras are important to everyday life not just within coding

[mental rover]

perhaps - learning can be hard, some of the best things I've learnt have been from not having the slightest clue how anything works while staring at a page in complete confusion for days

[unreal temple]

lol

what the hell are they doing every day

"useful for measuring things around the house"

[mental rover]

but you try things out, experiment, figure small details out, and at a certain point it can click and you have a fantastic platform of knowledge to build on

[serene egret]

hiya! i was wondering if i could get some help on writing a script? i'm trying to understand how instantiate works atm, and want to know if i could use instantiate to spawn prefabs to the right of the player.

[unreal temple]

Instantiate creates a copy of the object you pass to it.

typically a prefab

[mental rover]

everyday may be a stretch, but one of the biggest things you learn from mathematics in general is confidence & competence in calculation and general problem solving - having a solid understanding of trigonometry and geometry in general really can help with your intuition in every day life - you wont sit down with a pencil and start calculating a hypotenuse like you would in school, but you will intuitively understand a diagonal is longer, and about how much longer, etc

[serene egret]

 private void Spawn()
    {
        if (Input.GetKeyDown(KeyCode.E))
        {
            Instantiate(ladderPrefab, player.transform.position, Quaternion.identity);
            Debug.Log ("E key was pressed.");
        }
            

        if (Input.GetKeyDown(KeyCode.Q))
        {
            Destroy(ladderPrefab.gameObject);
            Debug.Log ("Q key was pressed.");
        }
    }```

i've got this atm, is there anything wrong with it so far?

[unreal temple]

```cs
// format code like this
```

// format code like this

[serene egret]

mb!

[unreal temple]

What is InstantiatePrefab?

[unreal temple]

cs on the same line as ```

[serene egret]

ack

[unreal temple]

without a space

nice, that's it

[serene egret]

oh sweet

that works :O

[unreal temple]

What is InstantiatePrefab?

[serene egret]

its supposed to say instantiate sorry

i forgot to update it

[unreal temple]

then what is the problem?

[serene egret]

the prefab doesn't spawn whenever i press E

[unreal temple]

@serene egret if you're making mistakes like that, it sounds like your IDE isn't configured. You should set it up using the guide in #854851968446365696, then it will autocomplete the correct name.

[serene egret]

appreciate it!

[unreal temple]

The test for whether E is pressed should be in Update

Or you can call this function from Update

Where are you calling it?

[late lion]

Destroy(ladderPrefab.gameObject); is an error. This is trying to destroy the original prefab asset, not the copy you created.

[bold terrace]

How do I convert X value and Y value from a string to an Vector2INT? For instance lets say I have string and its value is "X20Y10". How do I convert it to a Vector2INT?

[serene egret]

ive put the code into update so now that its formatted like this

    private void Update()
    {
        dirX = Input.GetAxisRaw("Horizontal");
        rb.velocity = new Vector2(dirX * moveSpeed, rb.velocity.y);

        if (Input.GetButtonDown("Jump") && IsGrounded())
        {
            jumpSFX.Play();
            rb.velocity = new Vector2(rb.velocity.x, jumpForce);
        }

        UpdateAnimationState();

        if (Input.GetKeyDown(KeyCode.E))
        {
            Instantiate(ladderPrefab, player.transform.position, Quaternion.identity);
            Debug.Log ("E key was pressed.");
        }
            

        if (Input.GetKeyDown(KeyCode.Q))
        {
            Destroy(ladderPrefab.gameObject);
            Debug.Log ("Q key was pressed.");
        }
    }

[serene egret]

is there a way i could use instantiate and key inputs to spawn prefabs instead of deleting the original prefab i already have in the scene?

for e.g. say the scene doesn't have the prefab, the key inputs would be responsible for spawning and deleting them

[late lion]

If you know for certain that the string will always be in this format and you don't need to be able to handle incorrectly formatted strings, all you need to do is find the index of the 'Y' character and then you can extract the substrings for the two numbers.

The X value will always start at index 0 and go up to where the 'Y' character is. The Y value will always start after the 'Y' character and go up to the end of the string. Then you can use int.Parse on those strings.

[mental rover]

lots of different ways to do this, you could parse by character, use split/replace operations, substring by index - personally I'd just default to using a Regex expression and extracting the numbers into a MatchCollection, e.g \d+ will match any number of digits

[late lion]

What should happen if the user presses E multiple times and spawns multiple ladders, and then presses Q once? Which ladder should be destroyed?

[serene egret]

to be honest i only want the user to be able to spawn one ladder at a time

whenever searching up how to code a toggle function

instantiate is what came up so i've been fiddling with that so far

[slim spruce]

thanks for the refactor! that made the code a lot cleaner, but the issue still persists. i'll attach a video of what i mean to hopefully explain it further.
same deal, removing the gravity removes the issue here, but that's not a solution.

[bold terrace]

Thank you, ill check it out

[devout solstice]

is there a way to get it from the addlistener, or something without having to use tags or add anything to each object? It’s just there’s quite a few buttons in the list

Oh wait i do have a unique name

How would I see if it was the one that was pressed though

[sage kite]

I'm making a game in VR where you are flying on a magic carpet, i want to grab the air in VR and make the carpet follow my hands rotation

Any idea how?

[clever harbor]

How can I generate a Mesh with multiple materials? Specific areas/quads of the mesh will have a different material

[potent sleet]

pass the button through a delegate

[mental rover]

the VR controllers will be mapped to a GameObject for each hand, possibly varying in structure depending on the exact VR framework you're using - movement/rotation can simply use the position and rotation of those objects. You could also look into using the input axis deltas directly, but just building on the framework is probably easier

[devout solstice]

idk how delegates work

[potent sleet]

https://youtu.be/VgwP1uXNnCw

[devout solstice]

will this teach me what i need, to do what i’m trying to do?

[sage kite]

hmmm, I'll give it a try, but won't it bug out if it will look at both controllers at the same time?

[potent sleet]

maybe. what do you need to do with the button

[devout solstice]

I just need to get what buttons being pressed when the addlistener is called

[mental rover]

possibly - you'll need to implement something and iterate on it to behave how you want

[devout solstice]

I have a inventory system, and when one of the slots is clicked i want it to drop the item

[potent sleet]

are buttons in a list ? just pass the index no?

[sage kite]

That's the tricky part

[devout solstice]

Yea the buttons are in a list, I’ve thought about that but how do i pass the index when the addlistener is called, i have a for statement iterating through the list putting the addlistener on each button

[potent sleet]

ehh.. that's why I told you about delegates xD

[devout solstice]

Alright and that video will show me what i need?

[mental rover]

yes, but that's where a lot of the problems with VR come in - user interaction is different, two free controllers and headset, each with separate position and rotation, are a novel input system and figuring out how to utilise that for interesting gameplay is basically what VR development is all about

[potent sleet]

look at the example here as well, you see you can pass params and whatnot
https://docs.unity3d.com/2019.1/Documentation/ScriptReference/UI.Button-onClick.html

[mental rover]

I'd start by trying to implement something that is line with what you want, using simple gameobject tools you're familiar with, and then come back with specific questions if it's not working how you want it to

[potent sleet]

you can pass an INT, or the Button object itself

up to you

[devout solstice]

How do I use the delegate with my script to pass which object is pushed though

[potent sleet]

the same way the examples on the page show you how to pass params

[devout solstice]

Ok i think i’ve got an idea

[slim spruce]

would still really appreciate some help with this, i'm honestly stumped and barely know where to even start with solving this.

[potent sleet]

there is literally what u wanna do on the site cs void ButtonClicked(int buttonNo) { //Output this to console when the Button3 is clicked Debug.Log("Button clicked = " + buttonNo); }

[devout solstice]

Using the third option and passing which index it’s on in the list would work right?

[devout solstice]

Alright that’s what I was thinking thanks

[potent sleet]

yes , Button is a type and could be passed as well

[hollow stone]

Anyone know how this can happen? 😵‍💫 And how to make sure it doesn't happen again..

[leaden ice]

What is "this" which you want to stop from happening

[hollow stone]

If you see the image, one image is when clicking on a prefab in inspector, and the other when opened in prefab editor. So there is information that doesn't seem to be serialized correctly. I've had this on a few of my prefabs. I've resorted to recreating the prefab and it has solved it for now.

[leaden ice]

Is this a prefab variant?

[hollow stone]

Yes

[leaden ice]

The image on the right really seems like it's not the prefab itself but an instance of the prefab 🤔

Mostly due to this

oh wait nvm

I see

Got a little confused with the naming.
Is the field in question properly serializable?
Are you using Odin Serializer or anything?

[hollow stone]

Yes, Yes

[final nymph]

Hello guys im beginner here

[severe maple]

im casting a raycast downwards in front of my player to check if there is a drop. If so, I disable the input vector2 completely (so he can't walk off ledges). However, if I am say running diagonal towards that ledge, he stops dramatically, whereas it should allow movement ALONG the ledge, just not straight off. Any idea how I would go about that? I take it involves disabling the input vector x or y that relates to the direction the ledge is in, but not sure where to start

[final nymph]

I wanna ask. How to make when the bird hits pipe then scene change to restard the gam?

[uncut plank]

it's a multi-step problem so split it in pieces:
-Make a function that restarts the game (reloads the scene)
-Use colliders to detect collision between the bird and the pipes

[final nymph]

Ty bro

Ill try it tomorow

Cus now i want to sleep

[potent sleet]

also this is #💻┃code-beginner question

[potent sleet]

you have to give more context, it's hard to say what ledge even is without knowing what type of game/prospective you're working with

[severe maple]

in 3d space, but controlled from a top down style. A ledge meaning any kind of sheer drop. I dont want to create invisible walls all around my map I'd rather do it via code

basically this: https://stackoverflow.com/questions/73582666/unity-blocking-character-from-walking-off-ledges

[leaden ice]

I don't think a single raycast is enough information for this kind of thing

[potent sleet]

honestly this is prob the best solution that comes to mind

anything else will be extremely complex and not counting for edge cases

just my 2cents

[severe maple]

i've got a single one in front, and i guess I need at least one at the front left and right as well. So if the front detects a drop, check either side and steer the input vector towards that

[leaden ice]

literal edge cases 🤣

[potent sleet]

disabling movement is an ugly way to do it

[severe maple]

any way to alter the movement vector2 I wondered? the drop will be at player.transform forward

[potent sleet]

would it really be that much to add invisible colliders, how many ledges do you really have

[severe maple]

well some levels are using terrain and drops all over the shop

[steady moat]

+1 for invisible collider

[potent sleet]

probuilder has literally a drawing tool

put the view Top down

and draw a giant thing around the egdes

[severe maple]

I have been doing invisible colliders, but what about procedural levels, would have thought there would have been a way to do it somewhere online lol

[steady moat]

Invisible Collider can be done in procedural generation

[potent sleet]

ofc its possible, anything is. it's just gonna be lot of math to deal with and consider all possible vectors which player will hit ledge from

[severe maple]

good point

[potent sleet]

colliders are way easier

[west prairie]

need help

[brisk reef]

Is it just me, or is probuilder really weird to use?

[potent sleet]

No it's not, also not a code question. #🛠️┃probuilder

[brisk reef]

well I just wanted to discuss it

not like you are forced to either ask or respond to questions here right

[austere apex]

Hi, I would need a bit of help figuring out the following (in 2d): Let's say I have a player and a tree (static object). Both have rigidbody2d and a collider (non trigger) attached to them. How can I make such that a player can pass through another player, but not through a tree. At the same time player x player collision or player x tree collision would take place.

[polar marten]

use the collisions matrix in the physics 2d settings

[austere apex]

I have tried it, but I can't "uncheck" player x player layer collision because I need them to take place

[polar marten]

what is your goal?

[polar marten]

how many players are there

[austere apex]

Does it matter a lot? If so then suppose there is a max of 40 players in a scene. Otherwise we can just take 2 players

(the game is planned to be multiplayer)

[polar marten]

I have tried it, but I can't "uncheck" player x player layer collision because I need them to take place
are you trying to say you need to know when players hvae collided, but you do not want them to push each other physically?

create a hierarchy with a separate player trigger layer and player layer

[austere apex]

yes

[austere apex]

could you expand on that?

[polar marten]

Player (layer=Default)
 TriggerCollider (layer=Triggers)
 PhysicsCollider (layer=Players)

[austere apex]

oh I see how this can work. Will try it out. Thanks!

[polar marten]

it's okay to have multiple rigidbodies

i wouldn't overthink this

[polar marten]

generally, for platformers, you can't use rigidbody physics for movement

[austere apex]

oh really, never tested that :D

[polar marten]

you can explore corgi engine 2.5d for ✅ multiplayer ✅collide and slide physics

if you want your movement to be traditional platformer movement

you will not be able to use rigidbody physics for it

does that make sense?

[sleek bough]

Hello, Just want to ask why my BoxCast also detect the object behind of the other object with same layer? I only want to detect on whose in front or above

[austere apex]

my game is not a platformer though

[leaden ice]

it will detect whatever the first object is that it hits

[austere apex]

it's just topdown

In brief, moving a circle shaped player in x, y and rotating that circle in z

[polar marten]

i see. you can look at the moremountains topdown engine

which also has multiplayer

topdown movement has many fewer traditions

but i'm not sure you want to be futsing about with this stuff if it's already all made in an asset

[austere apex]

Thanks for the suggestions, I thought of using Unity's multiplayer

[polar marten]

if it's topdown

you should be working in the xz plane, not the xy plane

i think you should look at this moremountains top down engine asset

really depends what your goals are

[sleek bough]

I have an instance where it also detect what's behind of it, not sure if its because my collider are thin

[paper rivet]

Does the information saved with PlayerPrefs persist between updates of an android app?
If yes I have a problem: I have changed the format of the data structure with which this information is saved.
Any suggestions for how to handle this breaking change?

[leaden ice]

wdym by "also"? How are you getting more than one result?

[polar marten]

Any suggestions for how to handle this breaking change?
you can read about the general programming concept of migrations.

[paper rivet]

so, is that true what have i said?

[polar marten]

Does the information saved with PlayerPrefs persist between updates of an android app?
yes

[sleek bough]

It should be only detecting "Card (3)" which on the top but it also detect the ones that is behind of it, check the debug

[polar marten]

you can set a debugging breakpoint on the interactUI.SetActive(true) line and see what happens

[leaden ice]

you'd have to show where the raycasts are originating etc.

those cards are splayed out in a way where the top of the bottom card is exposed for example

your boxcast could just be hitting that

[safe ore]

its fine its been fixed now thanks anyway

[warm shadow]

So I have an issue, this code is suppose to only run once, with the oneTime bool, but it still runs every frame and it spits out an NullReference Exception. Can anyone see what it is I'm missing?
Here is the code:

if (scene.name != "StartScene" && oneTime == false)
        {
            slider = null;

            slider = GameObject.FindGameObjectWithTag("Slider").GetComponent<Slider>(); //NullReferenceException here
            slider.value = startVolume;

            oneTime = true;
        }

[leaden ice]

the fact that it's spitting out the exception means oneTime = true; is not running

you need to fix the exception

[warm shadow]

yes, but how?

[leaden ice]

NREs are easy. Figure out WHAT is null

and fix it

in your case either GameObject.FindGameObjectWithTag("Slider") is returning null OR the returned object doesn't have a SLider component on it so GetComponent<Slider> returns null

DO you actually have an:

• active object
• with the tag "Slider"
• with a Slider component on it?
  in the scene?

At least one of those three things is missing

[warm shadow]

The gameobject is not active when you load the scene, and the NRE disappears when you activate it

Does that have anything to do with it?

[leaden ice]

yes

that would be the first thing I mentioned

- active object

FindGameObjectWithTag only finds active objects

[warm shadow]

ah sorry, i see, but how do i do it with inactive objects?

[ember lance]

is there an alternetive to make a ~class~ instance deheriving from it without having it in the scene?

[vocal merlin]

FindObjectsOfTypeAll works on inactive GameObjects

[leaden ice]

If you don't intend on attaching your class to a GameObject as a component, don't make it a MonoBehaviour

[leaden ice]

I think the better question is why are you using FindGameObjectWIthTag in this situation at all? Do you have a good reason?

Can you not just directly reference it?

[ember lance]

I was going to have it be atachable but, I guess I have to figure out a work around for my sulotion, thanks for the help!

[leaden ice]

Maybe if you explain what exactly you're trying to do, we can suggest something.

[serene egret]

im getting this error message,
'Health' does not contain a definition for 'fillAmount' and no accessible extension method 'fillAmount' accepting a first argument of type 'Health' could be found (are you missing a using directive or an assembly reference?)

and the code i have is,

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

public class HealthBar : MonoBehaviour
{
    [SerializeField] private Health playerHealth;
    [SerializeField] private Health totalHealthBar;
    [SerializeField] private Health currentHealthBar;

    private void Start()
    {
        currentHealthBar.fillAmount = playerHealth.currentHealth / 10;
    }

    private void Update()
    {
        currentHealthBar.fillAmount = playerHealth.currentHealth / 10;
    }
}

i've been trying to find the problem for a while now, but no luck. can anyone see where i've gone wrong?

[leaden ice]

Did you define anything called fillAmount on your Health script?

My guess is you actually meant to use Image instead of Health for those fields, no?

[serene egret]

i haven't no

should i?

[leaden ice]

no...

you should use Image instead of Health

make sense?

[serene egret]

it's not making sense i'm so sorry

[leaden ice]

There's nothing called fillAmount on Health right?

So why are you trying to use such a thing?

You can't use things that don't exist

    [SerializeField] private Health playerHealth;
    [SerializeField] private Health totalHealthBar;
    [SerializeField] private Health currentHealthBar;```

see these?

You've defined them all as type Health

so if you do currentHealthBar.fillAmount it's looking for a fillAmount property from the Health script

which doesn't exist

hence the error

I'm guessing what you MEANT to do was:
[SerializeField] private Image currentHealthBar;

Image DOES have a fillAmount:
https://docs.unity.cn/Packages/com.unity.ugui@1.0/api/UnityEngine.UI.Image.html#UnityEngine_UI_Image_fillAmount

[serene egret]

by changing the fields Health to Image, i'm getting the same console error.

show the new code

also make sure you saved your changes.

Hello! I would like to copy a unity native class and make my own variation of it. I copied the entire native script into a new one and named the class differently. It throws a bunch of errors at me. Any idea why? The most common ones are:
"must declare a body because it is not marked abstract, extern, or partial Assembly-CSharp, Assembly-CSharp.Player"
"The type or namespace name 'Orientation' could not be found (are you missing a using directive or an assembly reference?)"

The weird thing is, even if I went and fixed those erros, why do they pop up in the first place, when they work just fine in their original script?

You can't copy unity native classes really

there's a whole C++ side to them that you don't have

the changes ive made were

    [SerializeField] private Health playerHealth;
    [SerializeField] private Health totalHealthBar;
    [SerializeField] private Health currentHealthBar;

to

    [SerializeField] private Health playerHealth;
    [SerializeField] private Image totalHealthBar;
    [SerializeField] private Image currentHealthBar;

and the console error didn't show up anymore.
turns out it was just a problem on my behalf sorry sorry

[arctic panther]

its a bit hard to explain so let me phrase it like this: As a unity developer I want to create an editor with a graph view that can make use of nodes. Those nodes have Ports, but the native Unity version of those ports are not working like I need them.

So my first thought was to make my own Port. inheriting from the same master class as Port, copying the script and adjusting it as I see fit.

[leaden ice]

What's the limitation with GraphView that you want to work around?

also #↕️┃editor-extensions is probably the best place to discuss GraphView

[arctic panther]

GraphView.Port has the following things that misfit my usecase:

• ports are either "in" or "out". I dont need a flow in my graph view, I just need connections. (A is connected to B), without any direction
• aesthetically: orientations. They arrange the connecting lines in a way that looks fine for a classic node flow, but Id rather have them go straight from A to B. Also I want to decide on the color of those ports.
• the Port name is a string, I need it to be an inputfield

[arctic panther]

thank you, I will go there

[strong forge]

Ok, so my issue is that my fields do not show up in the Inspector despite having the SerializeField attribute. (They show up in the debug but not the normal one)
This is the class in Question and it's fields (excluding methods as they are irrelevant.)

public class StateSwitchButton : NetworkButton
{
    [SerializeField] private Sprite enabledSprite, disabledSprite;
    [SerializeField] private Image enabledStateImage;
    [SerializeField] private bool defaultEnabled = false;

    [SerializeField] private UnityEvent onEnable, onDisable;

    private bool isEnabled;
}

And the class NetworkButton which it inherits from looks like this (excluding methods once again):

public abstract class NetworkButton : Button
{
    public static readonly List<NetworkButton> buttons = new List<NetworkButton>();
}

I've read somewhere that in some cases inheritance breaks the inspector, which would be a serious issue as the inheritance is required unless I pull out some workarounds.

This happens to every class inheriting from NetworkButton btw.

[leaden ice]

Are you deriving from UnityEngine.UI.Button?

[strong forge]

Yes

[leaden ice]

That class has a cusotm inspector

so it's drawing with that custom inspector

which is why your fields aren't showing

[strong forge]

It worked before, it just stopped for some reason yesterday, I guess I'll have to write a custom inspector to override it, great.

how to handle screen and sprite sizes in a 2d game for mobile?

https://gamedev.stackexchange.com/questions/79546/how-do-you-handle-aspect-ratio-differences-with-unity-2d I have found this, but maybe it's outdated

first time playing with mobile

[warm shadow]

Sorry for the late reply, had to go quickly, but yes the script is attracted to gameobject on another scene, and is set to dont destroy on load, and this is the part where i get the new slider in the new scene, this was just the quickest way i could think of, but please tell if there is a better way

[leaden ice]

Could use the singleton pattern.

[warm shadow]

I haven't used those before, but i'll look into it, thanks

[hollow creek]

hello, can anyone tell me why i am getting this error?
i had ml agents 1.0.8 package installed and i updated it to 2.0.0 and then that error appeared

[foggy maple]

is it preventing you from compiling or play testing?

[hollow creek]

yes

[warm shadow]

Right so i looked into it a bit, but I'm unsure how i would go about linking the new slider to the script once i load the new scene...

[leaden ice]

you'd just access the singleton wherever you need it:

MySingleton.instance.whatever```

that whatever could be a reference to your slider
or a function that disables the slider, whatever you want.

[foggy maple]

try reinstalling the package or something as that error is quite vague, just means it’s can’t find a file

[warm shadow]

ohh, you mean to make the slider object a singleton?

[leaden ice]

whatever you're trying to access easily, yes

[hollow creek]

i did, its still there

[warm shadow]

ahh, okay i see, thanks

[spare karma]

Does someone have an idea why the editorloop keeps spiking every second on the playerloopcontroller? Some issues mentioned opened asset store window but I set the view back to default and it keeps happening

[devout solstice]

Is it causing issues?

[spare karma]

Yes, sometimes it causes a little stuttering. It’s a high end pc so there seems to be a problem somewhere

[soft shard]

You could try enabling "Deep Profile" and "Call Stacks", then expanding where it says "No Details" in the bottom right to show more details and run the profiler again - itll consume more RAM, but will also let you dive deeper in the raw hierarchy so you can (hopefully) see what Unity is actually trying to do during those spikes, then you can loop up those specific calls on Google, if they are documented it could give you a good indication of what it does, if not, maybe youll find a forum post about it, otherwise you may be left to investigation and trial/error (disabling certain editor windows one by one until you notice a difference)

[severe maple]

is it possible to adapt a minimap render texture camera to make it look something like this? I can understand how to do the icons easily, but I guess it would be a lot of work for walls? I was wondering if its possible to only render specific textures on layers, eg the floor textures and block everything else out, so the minimap will resemble the level layout

[spare karma]

Thanks, will try it out

[leaden ice]

you can use a camera's culling mask to only render certain layers

I'm having a hard time creating an Asset Bundle. Whenever I attempt to create the asset bundle, I get an error are you missing an assembly reference? My prefab uses scripts that reference a package (https://github.com/Unity-Technologies/com.unity.webrtc), but I'm unsure on how to include the namespace from that package.

[leaden ice]

https://github.com/Unity-Technologies/com.unity.webrtc#installation

I get an error are you missing an assembly reference?
If this is a compile error you should share the full compile error and the code that causes it.

[elfin wedge]

Yes, so I have got that package working, but when I try to make my prefab into an assetbundle I get an error

My code and the package work until I attempt to build the asset with the asset builder browser/script:
(https://docs.unity3d.com/Manual/AssetBundles-Browser.html)

If I build to exe or android app, everything is fine

I want to use my prefab as an asset bundle in another project

[elfin wedge]

error CS0234: The type or namespace name 'WebRTC' does not exist in the namespace 'Unity' (are you missing an assembly reference?)

[leaden ice]

on what line of what script

the full error message

[elfin wedge]

D:\Github\DesktopVisionUnityPackage\Runtime\Scripts\DVConnection.cs(2,13): error CS0234: The type or namespace name 'WebRTC' does not exist in the namespace 'Unity' (are you missing an assembly reference?)

[leaden ice]

Is DVConnection your code?

[elfin wedge]

Yep

[leaden ice]

Do you have an asmdef?

[elfin wedge]

I don't know

[leaden ice]

You don't know?

Check

it's an asset, in your asset folder. Assembly definition file

https://docs.unity3d.com/Manual/ScriptCompilationAssemblyDefinitionFiles.html

[elfin wedge]

I do not appear to have one

[leaden ice]

webrtc does though

https://github.com/Unity-Technologies/com.unity.webrtc/blob/main/Runtime/Unity.WebRTC.Runtime.asmdef

Their asmdef is listing specific platforms for the assembly to exist

I'm not sure exactly how asset bundles work but... seems like their assembly is not included when building the bundle

[elfin wedge]

Hmmm

[leaden ice]

Do you pick a target platform when making an asset bundle?

(I've never done it)

[elfin wedge]

I'm learning about the asset bundle right now, so I can't say for sure lol. Been running into issues immediately

but I believe so

"Build Target"

[leaden ice]

whats in advanced settings

[elfin wedge]

this is what I see when I open the Unity Asset Bundle Browser tool

Anyone has any idea how to save a GameObject that was created in PlayMode along with all its components? I was taking a look at this https://github.com/inkle/Unity-Save-Play-Mode-Changes/blob/master/Assets/PlayModeSaver/Editor/PlayModeSaver.cs but holy shit his code is dogwater

[leaden ice]

cheeky way is ctrl+C it in play mode

then paste in edit mode

[glad mirage]

yeah, but i want my tool to be seamless.

[leaden ice]

you can just write it to an asset in code

[glad mirage]

you can? what's the API

[leaden ice]

e.g. https://docs.unity3d.com/ScriptReference/PrefabUtility.SaveAsPrefabAsset.html

[glad mirage]

ok lemme try

FUCK it works

thanks alot. i wish i knew this earlier. there goes 5 hours :c

[warm shadow]

Does anybody know why im getting these errors when i try to build my game?

[simple egret]

One of your scripts references Editor stuff, it's not possible in a build.

You'll need to exclude it from the build (put it in an Editor folder for example)

[grim marlin]

I made a function, for my player mouvement (first person), It works but I think their are some big problem on it ? Would someone be available to help me fix/review it in a quiet place ? ❤️

I would like to have a good base to start my project.

[simple egret]

You can create a thread if you're afraid more conversations would bury your questions

[warm shadow]

Is using "UnityEngine.EventSystems" Editor stuff?

[simple egret]

No, anything under the UnityEditor namespace

[warm shadow]

so it needs to say Using UnityEditor

[simple egret]

Yes

[warm shadow]

okay

ill check

[simple egret]

The error has the faulty script btw

ToolsManager, line 6

[warm shadow]

ohh i see, that weird, i dont even use that, anyways thanks a lot

question so i've been creating new scriptable objects in runtime via constructor rather than create instance function. Is there issue i should worry about for continuing to do it this way?

[craggy totem]

Hello can someone help with Rotations,
I want to rotate Car's shadow (plane) according road's Normal (Raycast). shown in GIF (20mb can take some time to load)
Rotation along Axis Z and Axis X works as i wanted, but i can't find how to make axis Y repeat after RayCast (Car) gameObject rotation. thx

[simple egret]

From what I'm reading you need to use CreateInstance because if you use new, then Unity won't be able to call its special methods like Awake or Start

[grim marlin]

Would there be a good place on the discord for that, or would you recommend a particular place ?

[viscid kite]

so this will affect all scripts with start and awake or just the scriptable objects?

[simple egret]

If your question is about code, any of the 3 code channels will do (depending on how difficult you evaluate your question)
Else, see #🔎┃find-a-channel for the channel list, and create a thread in the most appropriate one.

[simple egret]

Just the SO instance. Sorry I phrased it badly

[...] then Unity won't be able to call the special methods like Awake or Start, on the SO instance.

[meager crown]

Is there a channel with people looking for partners/teammates? (sorry if this is the wrong place)

[simple egret]

Collab requests should be made on the Forums indeed

[meager crown]

oh ok thanks

[cyan hill]

hi all, i've added movement, but i'm getting stuttering when moving. the stuttering also seems a bit random and not really at specific points each time. why might this be?

video: https://streamable.com/gfsxrb

the way i'm doing it basically has each tile as a cube object and i'm re-parenting the character object into each tile along the way. i then have an Update() on the character object to do a MoveTowards localposition of 0, 0, -2 (to stand on top of the tile). the re-parenting is part of a co-routine.

1. pathfinding finds a specific ordered list of tiles to move through, to avoid objects
2. re-parent the character to the next tile, delay, repeat til the end
3. meanwhile as above ^ : keep updating the character's local position to 0, 0, -2, with MoveTowards

i've also tried it with packing the movetowards into a while for when the position isn't equal to the target.

both codes here: https://pastebin.com/2si5Vk74

[viscid kite]

didn't know they can use awake and start that said for the objects in question i guess it's better to do it via constructor

for me at least since i need to not only create it but also create it based no parameters

still glad to know there's no major ramification for doing so

[simple egret]

I would still use CreateInstance myself though. If you choose to use new test thoroughly especially in a build, where their "save" behavior is different

[full bluff]

Does this also apply to Destroy() ?

[simple egret]

You can't Destroy a ScriptableObject instance because it doesn't live in a scene

[full bluff]

ups i overlooked that you were talking about scriptable objects

It just jumped out at me since i had struggle destroying an object which i created through a "regular" c# class

[leaden solstice]

You can Destroy SO. Like how you destroy Sprite or Material. It's cleaning up C++ side resource of UnityEngine.Object

[leaden ice]

Unchecking "Sort completion suggestions based on machine learning" fixes it. Go away silly machines

Hmm, mine is disabled for C#, but I've never seen this setting.

Maybe because you upgraded from an earlier version

[faint scroll]

i get following error trying to set up velocity over lifetime of my particle system:

Particle Velocity curves must all be in the same mode
Code:

var vel = children.GetComponentInChildren<ParticleSystem>().velocityOverLifetime;
//vel.space = ParticleSystemSimulationSpace.Local;
AnimationCurve curve = new AnimationCurve();
curve.AddKey(0.0f, 1.0f);
curve.AddKey(1.0f, 0.0f);
vel.y = new ParticleSystem.MinMaxCurve(-180 * Throttle, curve);
vel.x = new ParticleSystem.MinMaxCurve(0,0);
vel.z = new ParticleSystem.MinMaxCurve(0,0);

Can someone help me here?

[clever spade]

After testing, you need to set the velocity to use curves. Just pass in a curve with 0 key and value if you want it to be zero and it will change it

[faint scroll]

i just got it, i simply didnt pass a curve but two times a value

[clever spade]

        vel.x = new ParticleSystem.MinMaxCurve(0, new AnimationCurve());
        vel.z = new ParticleSystem.MinMaxCurve(0, new AnimationCurve());
``` something like this would work too

but I'm not sure if that would use a default set by you or an actual empty curve

[modern creek]

My android performance feels a little sluggish. Is there any unity functionality/libraries/api to get the framerate on Android (or any) device? Or do I need to roll my own and count updates?

[void basalt]

You can remotely profile it

using the unity editor

[modern creek]

Hm, I haven't done that before.. I'll try, though. My own personal phone does weird shit when I try to put it into debug/usb mode (spam disconnects/connects in windows), but I was more hoping to start by verifying that the framerate is <60 or <30 or whatever the target framerate is for some of my team's devices.

[regal marsh]

I have limited experience working with navmeshes. is there a way to only have an agent move towards the target if the target is within a certain distance of the agent? it's a zombie horde game so i don't wanna check that on too many zombies at once in update because it might affect performance.

[leaden ice]

use a trigger collider to detect when something is in range

[edgy lynx]

How do you all manage your events?
For a brief example, let's say I had:

public class ShootController : MonoBehaviour
{
    public delegate void OnPlayerShoot();
    public static event OnPlayerShoot onPlayerShoot;

    public void OnShoot(InputValue _) // Using Unity's Send Message Input System
    {
        // shoot bullet code.
        onPlayerShoot?.Invoke();
    }
}

public class CameraShootEffect : MonoBehaviour
{
    private void OnEnable() => ShootController.onPlayerShoot += CameraShake;
    private void OnDisable() => ShootController.onPlayerShoot -= CameraShake;
    public void CameraShake() => Debug.Log("Shake camera");
}

In order for this to work, I would have to drag the CameraShootEffect.cs onto an empty object in the scene. So do you just create like a DDOL EventManager empty GO, that holds all your event data? Or what's a manageable approach to this?

[leaden ice]

Well the camera shoot effect script here seems like it should be attached to the camera

In that vein, I attach event listeners local to where their effects will be

[edgy lynx]

Awesome, thanks Praetor. Yeah, that makes complete sense, I kinda rushed the question out while it was fresh in my mind lol

[leaden ice]

Another example: a UI health bar could listen for HealthChanged events, and would live on the health bar ui

[vagrant blade]

My events are on the Controller script of an object. If that object has components which are local functionalities, they'll call a function on the controller to call the event.

That way everything outside the controller only has to deal with that controller.

[edgy lynx]

Makes complete sense.

[woeful leaf]

So I've this OnEnable

    private void OnEnable()
    {
        buttons = GetComponentsInChildren<Button>();
        for (int i = 0; i < 2; i++)
        {
            buttons[i].onClick.AddListener(() => Modify(buttons[i], Variable.Volume));
            print($"Index: {i}, Button:{buttons[i]}");
        }
        for (int i = 2; i < 4; i++)
        {
            buttons[i].onClick.AddListener(() => Modify(buttons[i], Variable.Level));
            print($"Index: {i}, Button:{buttons[i]}");
        }
    }

Which prints out the appropriate assigned buttons just fine. But when I run print(Array.IndexOf(buttons, button)); (the first line within Modify) it gives 2 for the top 2 buttons and 4 for the bottom 2 buttons. Any ideas as to why this could be happening?

[woeful leaf]

The expected result is that it'd give 0, 1, 2, 3, respectively, unless I'm misunderstanding the use of print(Array.IndexOf(buttons, button));

[woeful leaf]

Replacing print(Array.IndexOf(buttons, button)); with print($"Array number: {Array.IndexOf(buttons, button)}, Button: {button}"); explains it, it's associated with the wrong GameObject, though I'm still not how because this code seems fine?

Ah

I've had this same exact issue before

[woeful leaf]

Doing this instead of the other fixes it

private void OnEnable()
    {
        buttons = GetComponentsInChildren<Button>();
        for (int i = 0; i < 2; i++)
        {
            int j = i;
            buttons[j].onClick.AddListener(() => Modify(buttons[j], Variable.Volume));
            print($"Index: {j}, Button:{buttons[j]}");
        }
        for (int i = 2; i < 4; i++)
        {
            int j = i;
            buttons[j].onClick.AddListener(() => Modify(buttons[j], Variable.Level));
            print($"Index: {j}, Button:{buttons[j]}");
        }
    }

I don't know why, but it does work, and that's how I've fixed a similar issue in the past as well, which this idea was given in the first place there at that point

If someone could explain why that is how that works though, that'd be great

[leaden ice]
