When someone says a texture, it does not imply it is object or asset :/

[heady iris]

fair, I was distinguishing the wrong things there. I should've said that the Texture2DArray object you created is distinct from the asset that gets produced from it.

The behavior is certainly a little bit unexpected.

[dawn nebula]

Let's say I expect a value to be within the range of -1 to 1, and I want it where:

• If it's 0, it's 0.
• If it's above 0 it's 1.
• If it's below 0 it's -1.

Any quick math method to get this behavior?

[somber nacelle]

Mathf.Sign

ah wait, that returns 1 when it's 0

use Math.Sign instead
https://learn.microsoft.com/en-us/dotnet/api/system.math.sign?view=netframework-4.8.1

[dawn nebula]

Thanks.

Odd that the unity one has that behvaiour.

0 is not positive unity 😠

[swift falcon]

CS0103

what is this error

[somber nacelle]

read the error text

[swift falcon]

The name 'StartCoroutines' does not exist in current context

[somber nacelle]

well there you go, you're trying to use something called StartCoroutines but that doesn't exist

do you see it underlined in red in your code editor?

[swift falcon]

no

or visual studio code

[somber nacelle]

then you need to get your !IDE configured

[tawny elk]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)

• VS Code*
• JetBrains Rider
• Other/None

*VS Code's debugger plugin is unsupported.
We recommend using VS or Rider instead.

[somber nacelle]

after you complete those steps, spell the method name correctly. it's StartCoroutine

[knotty sun]

0 is positive
-0 is not positive

[silk cairn]

what is this person using in order to have 2 values in each item of their list?

[knotty sun]

an array of a class or struct

[silk cairn]

thank you

Im trying that but it doesn't seem to work?

[knotty sun]

because Requrement is not seriazable

[silk cairn]

i just tried that

still nothing

[knotty sun]

these classes should not be in the same script file

is Item also serializable?

[silk cairn]

no it is not

[knotty sun]

btw a ScriptableObject does not need to be flagged as Serializable

[silk cairn]

okay thank you

[knotty sun]

it you want to serialize Item it needs to be flagged Serializable as well

[silk cairn]

I seperated the scripts, made Requirement serializable and still nothing

my item is a scriptable object

[knotty sun]

how are you creating your SO's? I see no CreateAsset Attrbute there

[silk cairn]

the create asset menu is in the Item scriptable Object

[knotty sun]

and for RecipeSO ?

[simple egret]

I don't know if Unity will like constructors on these scripable objects

[knotty sun]

it most definitely will not

cannot call a constructor on a Mono or SO class

[silk cairn]

oh it worked

I had an error somewhere else so it wasn't loading the saves

[knotty sun]

ffs

[silk cairn]

my bad

[knotty sun]

even so what @simple egret said, you cannot have a custom constructor for Item

[topaz sapphire]

yeah this is come off as stupid

if i wanted to replace m1911 with a prefab from a script and keep the same position in the children array as its referenced that way in other scripts

[prime sinew]

Okay, what's the question here..?

[topaz sapphire]

.child(0) = prefab

[prime sinew]

That's not a question

If what you want to know is how to set the child position in the Hierarchy, then Google "how to change position of child in hierarchy unity"

[potent sleet]

you realize when you change 1 item it will change all of the scriptable object

[latent latch]

removing contents does not remove the index of the array if that's what you're asking

[silk cairn]

yes

[topaz sapphire]

oh so i can just destroy and instantiate then?

[latent latch]

as long as you use the same index

[prime sinew]

This is also a lesson to try not to have your logic depend on child order. Just add to a list or cache to a variable

[potent sleet]

just making sure you're aware :p

[prime sinew]

They are misunderstanding you

It's not the order in an array, it's the one in the Hierarchy

[latent latch]

Ah, right yeah that's a little different

[prime sinew]

@topaz sapphire

[latent latch]

if you did GetComponents it would just give a temp array basically of the references

[prime sinew]

Don't know if you're having trouble with the spawning, replacing, or ordering of the child because up till now you haven't actually asked a question

[topaz sapphire]

i have man

[prime sinew]

Where?

I don't know why you want to argue instead of clarifying

[topaz sapphire]

"if i wanted to replace m1911 with a prefab from a script and keep the same position in the children array as its referenced that way in other scripts"

do i NEED to put a question mark after?

[prime sinew]

Okay... And which part do you not know how to do

[prime sinew]

That's just an if statement

Do you know how to spawn an object?

[topaz sapphire]

i beg of you to kill your ego for 2 seconds dear god

[prime sinew]

Forget this

<@&502884371011731486>

[topaz sapphire]

keep making remarks then

@latent latch can you give me a hint?

you seem to know what your doing

[quartz folio]

They don't know what part of it you don't know how to do, and these are the questions you should be answering:

Don't know if you're having trouble with the spawning, replacing, or ordering of the child

[latent latch]

https://docs.unity3d.com/ScriptReference/Transform.html

[quartz folio]

What do you know how to do out of the question you asked, because there's multiple steps, just destroy the object, spawn it, then change the sibling index using the transform APIs

[latent latch]

There's a bunch of methods relating to shifting placement in the hiearchy that may be what you're looking for

[topaz sapphire]

man look, "thats just an if statement" and "okay... whats the question here?" and then walking around the answers already presented aint remarks then i dont know what is

[topaz sapphire]

thank you

[topaz sapphire]

thank you

[latent latch]

Yeah, you can just assign the sibling index if it's in the correct transform list

otherwise just move it to the first index if you're using 0

[topaz sapphire]

so delete, instantiate, update index

[latent latch]

Sounds about right

instantiate with the same parent as the previous prefab

[topaz sapphire]

done

watch this not work

it didnt work

[somber nacelle]

in what way did that not work?

[latent latch]

that text 0_0

[somber nacelle]

yeah that font is a war crime

[sleek hedge]

is that terraria

[topaz sapphire]

i wanted to change the windows desktop font

changed everything on accident

[potent sleet]

not as bad as comic sans

[topaz sapphire]

even the activate windows is corrupted

[lean sail]

this just gets more and more chaotic

id believe u if u said u were coding this on a samsung fridge at this point

[topaz sapphire]

yeah it didnt work because I forgot to call the function under the condition

it worked

[pale spindle]

Good evening friends.

I need to fire a sound via a audio clip. I have AudioSource and AudioClip in a empty child object called Audio Manager

But in my PlayerController, how do I access the clip from the other script?

[somber nacelle]

get a reference to the object. here are several ways you can do so: https://www.youtube.com/watch?v=Ba7ybBDhrY4

[pale spindle]

ok 🙂

this is my AudioController.cs in Audio Manager gameoject

using UnityEngine;

public class AudioController : MonoBehaviour
{

public AudioSource source;
public AudioClip torpedoFired;

}

this part is fine right?

i linked it in the editor too

[somber nacelle]

sure

[pale spindle]

ok

[prime sinew]

If you prefer text guide, there's also this
https://unity.huh.how/programming/references

[somber nacelle]

it's not really controlling anything here so the class name is kind of poor since it's just holding references to two objects. but i assume you're likely going to add some more functionality to this component?

[pale spindle]

video is better, adhd likes video

@somber nacelle not sure yet :/

where would you put your audio?

its a simple copyright clone of space invaders but my spin on it

for fun, not release/sell

all 2d

i subbedy to you too 🙂

[pale spindle]

ty too

[prime sinew]

Hey, sorry about earlier. I should have just asked for which part you needed help with, instead of picking on how you asked for help

[topaz sapphire]

yeah its alright man, just try to holdback on those remarks they come off the wrong way without tone

[pale spindle]

void PlayTorpedoSound()
{
audioManager.GetComponent<AudioSource>().clip = false;
}

well this is a fail

[somber nacelle]

that line doesn't make any sense

[pale spindle]

i got the first part right but not sure what to do at the end of ().

public class PlayerController : MonoBehaviour
{

[SerializeField] private GameObject audioManager;

[somber nacelle]

if you want to put nothing in the clip property then assign null because it's not a bool

[pale spindle]

ok

[somber nacelle]

but also, just reference the AudioSource directly, you don't need to reference the GameObject just to then call GetComponent on it

[pale spindle]

how do i do it direct then?

everything is different now in 2023, last time i did a clip was 2015

XD

[quartz folio]

Reasons to not make video tutorials: they're hard to update 😄

[pale spindle]

Unity Learn sucks as bad

[somber nacelle]

use the component's type as the variable type instead of GameObject, you know like i said in the video 😉

[pale spindle]

some of the stuff they have you do is missing/moved

[quartz folio]

My site doesn't though, which was the text one that was linked

[pale spindle]

ok

[pale spindle]

ok

i got the reference part but this is losing me

   void PlayTorpedoSound()
    {
        audioManager.GetComponent<AudioSource>().
    }

what goes at the end of .

[quartz folio]

You don't need to use GetComponent if you have referenced the component directly

[pale spindle]

ok

[quartz folio]

Do you have proper autocomplete and error highlighting in your IDE?

because you should be able to just see the members and access them easily as you type

[pale spindle]

yes but grr 😦

https://www.youtube.com/watch?v=ln4ilSVR1Ug

hes using PlayOneShot

I dont see that :/

even with the reference

[quartz folio]

Your audio manager is not an audio source though

it contains the variable that you need to reference first

[pale spindle]

ok :/

[somber nacelle]

you changed the variable type so you have to drag the object in again because it was previously serialized as a GameObject type

[pale spindle]

ok got it

[SerializeField] private AudioClip torpedoFired;

also dragged the CLIP in

but where is playoneshot?

[potent sleet]

[somber nacelle]

that's the AudioClip not the AudioSource

[pale spindle]

im doing a clip not music :/

oh, sec

[potent sleet]

AudioSource is like your radio

[pale spindle]

so do i want a clip or a source?

[potent sleet]

audioclip is the casette

[pale spindle]

i wish they would make 1 for all

ok

[somber nacelle]

the clip is the sound itself. the AudioSource is what plays the sound

[pale spindle]

void PlayTorpedoSound()
{
audioSource.PlayOneShot(torpedoFired);
}

we good i think ,testing

BINGO

ok it worked 🙂

So whats the best strategy for managing audio and clips in the future?

[potent sleet]

sound manager

[pale spindle]

as a empty game object? that's what i got now

i think its redundant

[potent sleet]

I would name the gameobject the same name of the script

[pale spindle]

fair enough, done

[potent sleet]

and yeah but as a singleton as well

@pale spindle
https://gamedevbeginner.com/singletons-in-unity-the-right-way/

[pale spindle]

why does things get more complex? soon unity is gonna demand 50,000 javascript libs :/

but i will check it out

[potent sleet]

javascript ?

[pale spindle]

was a joke since js is horrible in webdev

anyway reading, min

public class Singleton : MonoBehaviour
{
public static Singleton Instance { get; private set; }
}

So would this be in its own script in an empty object?

[potent sleet]

did you kinda just skim through the article ?

[pale spindle]

im trying to see if i need a gameobject, sec

[potent sleet]

any monobehaviors needs a gameobject .
doesn't need to be called Singleton though

[pale spindle]

Yes, jsutneed a empty, name it Audio Controller as my script is named. and add a class with just the singleton to it

and call the singleton anywhere i need it for audio in my other source code

[grand trench]

I followed this tutorial while trying to make a state machine to go ahead and add the movement to the player
https://www.youtube.com/watch?v=K1xZ-rycYY8&ab_channel=bendux
However, when I moved, I wouldn't stop moving when i let go of the key. To fix this for moving left and right, I added the line rb.velocity = new Vector2(0,rb.velocity.y); to my idle state, which stops the player when the state is idle. However, for jumping i'm not sure what to do. When i press space, the player just flies upwards at a steady pace and never falls back down. I'm very confused. Here is my script in the player (a lot of stuff in here isnt finished yet)

[potent sleet]

yea as it says use caution dont start using a bunch of static singletons everywhere, only when it makes sense to do so

[pale spindle]

sorry 😦

i will try harder

[potent sleet]

nothin to be sorry about just read the pros and cons lol

@grand trench

you should be doing the jump the same way the tutorial you're following is doing.

[grand trench]

Is it not the same?

[potent sleet]

you haven't posted the code correctly

did you read the bot msg?

[grand trench]

Yeah just give me a minute

[pale spindle]

@potent sleet

not gonna lie

    void PlayTorpedoSound()
    {
        Singleton.Instance.AudioController.audioSource.PlayOneShot(torpedoFired);
    }

looks way better and easier to access

[potent sleet]

noo don't access components directly

[pale spindle]

.... ok now what???

[potent sleet]

make methods

[pale spindle]

that is a method

[potent sleet]

not everything should be public

[pale spindle]

its called void PlayTorpedoSound()

[potent sleet]

you're getting the audioSource

and playing OneShot

[pale spindle]

yes

[potent sleet]

don't do that

[pale spindle]

using UnityEngine;
using UnityEngine.InputSystem;

public class PlayerController : MonoBehaviour
{

    public AudioClip torpedoFired;

    public Rigidbody2D rb;
    public GameObject torpedo;

    private float horizontal;

    [SerializeField]
    private float playerSpeed = 4f;

    public void OnMove(InputAction.CallbackContext context)
    {
        horizontal = context.ReadValue<Vector2>().x;
        rb.velocity = new Vector2(horizontal * playerSpeed, rb.velocity.y);
    }

    public static GameObject Create(GameObject prefab)
    {
        return Instantiate(prefab);
    }
    public void FireTorpedo(InputAction.CallbackContext context)
    {
        if (context.performed)
        {
            Debug.Log("Played sound!");
            PlayTorpedoSound();
        }
    }

    void PlayTorpedoSound()
    {
        Singleton.Instance.AudioController.audioSource.PlayOneShot(torpedoFired);
    }
}

this is the playercontroller.cs

so how do i do the "method" way now?

[potent sleet]

Singleton.Instance.AudioController.PlaySound(torpedoFired);

[pale spindle]

there is no PlaySound

[potent sleet]

smh

[pale spindle]

Singleton.cs

[potent sleet]

you make the method inside the audiocontroller

[pale spindle]

using UnityEngine;

public class Singleton : MonoBehaviour
{
    public static Singleton Instance { get; private set; }
    public AudioController AudioController { get; private set; }
    public UIController UIController { get; private set; }
}

which method?

PlaySound()?

ok

[potent sleet]

you're trying to run before knowing to walk

[pale spindle]

yes im 44 and have no life

i need to do something before i lose my mind :/

[potent sleet]

just my 2c : don't have to rush through it and take the time to learn the basics before mashing random code together

also your singleton class is missing the assignment

you're gonna get a NullRefException if you tried running it

[pale spindle]

using UnityEngine;

public class AudioController : MonoBehaviour
{

    public AudioSource audioSource;
    public static AudioClip torpedoFired;

    public static void PlayTorpedoSound()
    {
        audioSource.PlayOneShot(torpedoFired);
    }
}

[potent sleet]

Instance = null

[pale spindle]

😐

ok

adding it now

[potent sleet]

are you troling or

[pale spindle]

NO

[potent sleet]

why is this static
public static AudioClip
public static void PlayTorpedoSound

[pale spindle]

I said im adding the damn code check now for instance

because it's what I use in C# to access certain methods

I willr emove it

[potent sleet]

defeats the whole point of doing a singleton instance

also you cant assign static fields in inspector

[pale spindle]

ok, noted

mono is def different from full blown c#

i gotta get used to it heh

[potent sleet]

you wouldn't use static everywhere in regular .NET either

also unity is "full blown c#" just up to 9

there are specific things related to inspector and API unity only

[pale spindle]

basically what you had

and audiocontroller.cs

look fine now? :/

[potent sleet]

wtf are u doing mate

like seriously

[pale spindle]

oh ffs

[potent sleet]

where in the article is this the same ? btw

[potent sleet]

dawg, you put Destroy(Instance)

big difference

[pale spindle]

oops :/

tired 😦

[potent sleet]

perhaps take a break

[pale spindle]

I don't get time to 'code' this is my time :/

11:12pm

else i could stop sleeping and just use those hours, i work full time in a deli :X

[grand trench]

@potent sleet https://pastebin.com/wu3jFkkj

my bad for taking long i had to use bathroom

[potent sleet]

coding tired will just lead you to make dum mistakes like switching audiosource to static field and then trying to new () it 🤔 @pale spindle

[pale spindle]

fine :/

public class AudioController : MonoBehaviour
{

    public AudioSource audioSource;
    public static AudioClip torpedoFired;

    public void PlayTorpedoSound()
    {
        audioSource.PlayOneShot(torpedoFired);
    }
}

there nicer

i should now take a break

playercontroller:

    public void FireTorpedo(InputAction.CallbackContext context)
    {
        if (context.performed)
        {
            Debug.Log("Played sound!");
            Singleton.Instance.AudioController.PlayTorpedoSound();
        }
    }

[potent sleet]

TorpedoFired shold not be static...

why is is it still static

[pale spindle]

removed static , i forgot to there

[potent sleet]

this is way different than the tutorial, why don't you implement that first then go into the FSM ?

[pale spindle]

its a older line, fixed

no more statics, im not using em anymore for this kind of stuff then

[potent sleet]

try to keep static for helper methods in POCO classes

or Instances/Singleton

[pale spindle]

fair enough

i will get used to this new way, old habits i tried w/o any singletons/instances for audio

[grand trench]

its not way different its just that the functionality is within a function

[pale spindle]

now im finding it out the right away, gonna reread your article and also @somber nacelle and @quartz folio

[grand trench]

but its the same way he did it

[pale spindle]

just to be sure 😄

[grand trench]

as far as i know

i meant within a method*

the jump functionality happens within fixedupdate, and uses the same line he uses

yet it works differently, why?

[potent sleet]

send the video again, dont wanna scroll up

[grand trench]

alright

https://www.youtube.com/watch?v=K1xZ-rycYY8&ab_channel=bendux

[pale spindle]

I'm gonna chill and work on things when my head is clear, im off this weekend so it helps

Else all I'll do is spin my tires and burnout. 😂

[potent sleet]

ok what does your jump look like, can you make a vid ?

[pale spindle]

I do like this singleton approach tbh 🙂

[grand trench]

it just goes up at a steady pace and doesnt stop ever

[pale spindle]

Thanks for slapping some sense into me @potent sleet

[grand trench]

wwhich is the same thing my movement did but as i said in my original explanation, that was easy to fix

[potent sleet]

they are handy, just like everything else you use at discretion

[pale spindle]

Gonna netflix and chill and sleep.

[pale spindle]

Got it, will note it in Obsidian 🙂

Ok, time to unplug my brain and watch something and go to sleep.

[potent sleet]

if it keeps going up is clearly not the same lol

[pale spindle]

Thanks again

[buoyant crane]

case PlayerState.JUMP:
                Jump();
                sr.color = Color.gray;
                break;

Jump() is constantly being called

[grand trench]

ah

[potent sleet]

yup and video puts it inside a key

[buoyant crane]

technically it’s the same line, but the difference is his is being called once

and yours is being called every fixed frame as long as the state is Jump

[potent sleet]

++ "Followed exactly like tutorial, they did not"

[grand trench]

null

[buoyant crane]

call Jump() when you press input, not when the state is Jump

[grand trench]

omg

i just put the code in different places without thinking but i still followed how the tutorial made it

[pale spindle]

you pulled a core 😛

gg tho for seeing it tho

night all 🙂

[potent sleet]

I beg to differ

[grand trench]

what are you showing me

[potent sleet]

the video you said you did exactly like u did

[grand trench]

as i said i used the same line he did i just put it in the wrong place

[potent sleet]

thats why copying blindly without knowing why its where it is is generally a bad idea 😛

[void basalt]

^

[grand trench]

null shut up

[potent sleet]

its ok maybe next time you won't do it again

[grand trench]

i didnt copy it blindly asshole

[pale spindle]

im guilty of it sometimes

chill dimrod

[grand trench]

i was thinking about what i was doing i just thought wrong

[void basalt]

You need to chill

[potent sleet]

I mean it's just a suggestion not critisim no need to get pissy 😛

[grand trench]

i made the wrong decision, not like i turned my brain off and just threw some code down

[pale spindle]

thanks again @potent sleet @quartz folio and @somber nacelle ❤️

gonna go sleep and play with stuff tomorrow again

have a good one

i got inputs to work so im happy too 😄

[potent sleet]

[grand trench]

i actually didnt need to change where it was after all i just had to add an extra check to make sure you're grounded

so my thinking wasn't even entirely wrong

i just forgot one part

[carmine orbit]

I am trying to set a boolean array by accessing an equal part of another Gameobject array which works but the problem is that the GameObject array auto populates the array but the player states will not and it makes me auto increase the length in the inspector does anybody know why?
https://gdl.space/ayimulagor.cpp

[swift falcon]

is there any way to use game objects or prefabs as a class

so like if i have a game object cheese cake

i want to get information about it's transform, rigibody etc in a script

[void basalt]

Each script you put on an object, is a class.

[swift falcon]

right

[void basalt]

if your cheese cake object has a CheeseCake class, then yeah

I guess thats doing what you want

[swift falcon]

i guess what i'm thinking is

if i need to add or remove components at some point

i don't want to manually have to go change my CheeseCake class each time to reflect that

but i guess it's not a big deal

[void basalt]

For example, if you wanted to pick up the cheese cake as an inventory item, or eat it as some generic food item, you would use interfaces

Idk if that answers your question

[swift falcon]

interfaces are new tech for me so i guess i'll find out

[void basalt]

You can always create a base Food class

and then derive cheesecake from it

I'm not sure what you mean by add or remove components though.

If you change from a rigidbody to a character controller, then yeah you'll have to go in and edit the code

[swift falcon]

i guess if you wanted information about its position, you'd have to get its transform, but if you wanted its colour then you'd have to ask its material or w/e

[fervent furnace]

@carmine orbit the findobjectswithtag each time returning a new array…

[swift falcon]

so you'd have to go find every component individually

and even if you just made a cheesecake class, you'd have to assign all of its values individually right ?

[void basalt]

I mean, you could create variables. In Start(), you set each variable to the component you just searched for

then you just use the variables

[swift falcon]

like there's no "get all components attached to this game object" function or anything i guess is really what i'm asking

[void basalt]

No, because that wouldn't make sense

[swift falcon]

gotchu

[void basalt]

You could rig something up

that like, automates it

but no, theres nothing like that by default

[swift falcon]

ty

[rugged spear]

I need some advice. For my player movement script, what would you guys say is "best practice" to put all input detection and CharacterController.Move/other movement code all inside the Update method? Should I instead move all of the logic (including input) to FixedUpdate? Or should I use Update to store inputs as variable(s), and let FixedUpdate apply movement based off the stored variables?

[void basalt]

If you put it in fixedupdate, you'll need to write your own interpolator

[fervent furnace]

You can try gatcomponents<component> but ihavent try it before so i am not guarantee it will work, even if it works you will get a bunch of components that you dont know what they are

[void basalt]

fixedupdate ticks at a fixed rate. Default is 50hz

you don't want to increase that rate especially if you're screwing with physics

The professional AAA way to do it, would be to run all simulation logic at fixed rate, and interpolate visual renders on frame updates

if you're just beginning, you probably don't want to do that

[rugged spear]

why can't you just do something like Mathf.Lerp(something, something, something * Time.fixedDeltaTime) in fixed update?

[void basalt]

Because that's not how you lerp

If you're really curious, I could show you how to do it properly

[buoyant crane]

if there is, it won’t be as useful as you think it would be.
If you grab your CheeseCake GameObject and you know it already has a rigidbody using .rigidbody (doesn’t exist), it’s essentially the same as .GetComponent<Rigidbody>(). It would be a bit practical since less typing i guess, but not possible in c# without being extremely painful 🙈.
Likewise, if you wanted a collection of all components (rb, renderers, custom scripts) on the game object, that’s also possible using GetComponents<Component>() similar to what was said above me

[rugged spear]

So would the latter method be right direction then? So in FixedUpdate, only things like CharacterController.Move should be used. And also isn't detecting input only "reliable" in the Update method (and not FixedUpdate)?

[void basalt]

standby

writing you some code

[rugged spear]

understood, thanks in advance

[void basalt]

float tickDelta = 1 / tickRate; // Time between each tick
float timeAccumulator;

void Update() {

timeAccumulator += Time.deltaTime;

while (timeAccumulator >= tickDelta) {
timeAccumulator -= tickDelta;
CustomFixedUpdate();
}

float interpolationAlpha = timeAccumulator / tickDelta;
Vector3.Lerp(myObjectPosLastSimulation, myObjectPosCurrentSimulation, interpolationAlpha);

}


void CustomFixedUpdate() {

myObject.Move()...

}```

I wrote this in notepad. Some stuff might be wrong, but the idea is correct

you cant use unity's fixedupdate

you have to make your own clock

[rugged spear]

interesting

[void basalt]

otherwise you can't access the interpolator alpha

this is how it's done in multiplayer games

[rugged spear]

right, because Time.fixedDeltaTime is always 50hz (0.02)

I was wondering about that

[void basalt]

yeah, you wouldn't use fixedDeltaTime

just regular deltaTime

all we're doing is accumulating time to figure out when the next tick should be

[rugged spear]

i see

I'm assuming tickRate would ideally still want to be 50 to be as close to the normal fixed timestep?

Or it could be faster if I understand correctly

[void basalt]

cod warzone uses 10hz tickrate

it can be anything

lower it is, better performance you'll get

but less responsive

[rugged spear]

because Update (on most new systems) will be called much faster than 50hz

[void basalt]

Correct. Calling character controller updates or doing anything intensive in Update() is a massive waste

[rugged spear]

I see. This is a great point that I never even thought to consider until now

Thank you for this

So in theory FixedUpdate would only be useful for stuff involving custom physics?

[void basalt]

You can run any custom physics code in the CustomFixedUpdate I showed you above

That's really all unity's FixedUpdate is doing

there's nothing magic about it

but

you'll need to manually tick the physics engine

[rugged spear]

I'm just wondering what FixedUpdate is useful for then

[void basalt]

physics code has to be called on a fixed basis

it shouldn't run in frame updates

[rugged spear]

So in this example (which is my ideal usage) is myObject.Move()... not physics code?

[void basalt]

It can be a character controller, or rigidbody velocity sets, add force, etc

You'll need to disable automatic physics updates

and run this at the end of the while loop

https://docs.unity3d.com/ScriptReference/Physics.Simulate.html

Generally we call it a "Simulation Loop"

all simulation data should run on a fixed basis

so like shooting guns, moving, etc

[swift falcon]

kind of arbitrary but for reference older source games are 64 or 66, i think competitive cs:go servers are 120

[rugged spear]

So why is CustomFixedUpdate invoked in the Update method? What if the frame update stalls for a while (lets say 1 whole second for some reason)

[void basalt]

Easier said than done

especially when you're only running a map with 8 players with raycast guns

and nothing else

[swift falcon]

true

[void basalt]

That's why theres a while loop

the while loop catches up in case your game locks up

so yeah, you could have 2 simulation steps running in the same render frame

not uncommon

[rugged spear]

Ah yes good point, I didn't realize that

I see now

Sorry for my ignorance lol

Thank you for the explanation

[void basalt]

You're getting it better than most people

If you put it inside VS and format it correctly, you'll be able to read it a lot better

[rugged spear]

If I'm being honest this seems like a game-changer (literally) 😄

[void basalt]

ECS is the real game changer if you're looking for raw performance

[rugged spear]

This in particular is very interesting

[void basalt]

You must ensure that you disable auto physics updates or you're gonna get some weird results

[rugged spear]

So I would have to implement your example in every script that needs some type of physics step?

[void basalt]

You would generally write your own entity system

any object you instantiate, you would do it through the custom entity system

[rugged spear]

I see

[void basalt]

thinks like player rotations should also be handled in Update()

otherwise you'll get nasty input lag

As for the entity system, you could just create a new base class called SimulationEntity, or whatever you want

[rugged spear]

So I'm thinking I would make a system that's higher up in the script execution order that can register some type of "callback"

[void basalt]

then have all of your new scripts derive from that

yes, the class system ^ would handle that

[rugged spear]

I see

[void basalt]

On the base entity class, you would have SimulationUpdate()

then you can call it on any entity that derives from it

etc

[rugged spear]

right, gotcha

interesting

thank you for the pointers

[carmine orbit]

What would you recommend instead?

[rugged spear]

also it's interesting that you mentioned this.. Isn't that the network tickrate? I'm curious to know if the custom physics tickrate would matter in this case

[void basalt]

Network tickrate and simulation tickrate are both the same. All of their code runs from the same clock in a multiplayer environment.

[rugged spear]

ah okay

[void basalt]

that's why it's not logical for most games to just "up the tickrate" because then you run into bandwidth issues

[rugged spear]

yeah that makes sense

[rose stream]

can I ask some C++ related help here

its a simple question with which I am struggling

[void basalt]

@rose streamIf it's unity related, I don't see why not

[rose stream]

i am writing a native plugin C++ so i can import it in unity

[void basalt]

fire away

[gleaming burrow]

Heyy, First time asking for help here, so I hope this is the place to do it. >~<
I'm using a script to spawn random humans, with random meshes and texture. I was able to get the meshes working, but swapping the textures has proven to be a little more difficult.

From what I can tell the correct texture is being applied to the component as a instance ; what I want. But the original material is still there and appears to be overriding the instance texture.

public SkinnedMeshRenderer class1
public Texture Farmer1;
public int skinPicker;

skinPicker = Random.Range(1, 4);

if (skinPicker == 1)
{
class1.material.SetTexture("_MainTex", Farmer1);
print("Skin 1 Applied");

        }

Any help would be amazing, i've been looking online for the past 2 hours and I cant work it out.

[leaden ice]

Kinda looks like you attached two different materials to the object? Not enough context here really

[rose stream]

you can create a public texture array and assign the textures in the inspector
navigate through the array with a random number generated each time with time span
in that way
you can do the texture thing as well

[leaden ice]

also why did you name your renderer "class1"

[rose stream]

i think copy paste stuff happening there

[gleaming burrow]

there's only one mat assigned before the script adds a second one, would I have to delete the first mat somehow?

[leaden ice]

Just assign the new one

No idea why you're adding a second one

You have to show your code

[rose stream]

ok i have a question
in C objective you have a statement like char** argv
in which you give pointer to a pointer of a char
like char[][]
or like string[]
would this work in C++
where char** dont work as expected
they simple use char* and assign the value
or sometimes char* argv[]

also if its a char** argv
how can I call it in C#

[void basalt]

First of all. Do you really need to go into native?

Because it complicates things 100%

You can use pointers in C# if thats what you're after

[rugged spear]

char* argv[] is just an array of pointers, and so is char** essentially

[rose stream]

i am making use oggvorbis library to encode audio packet into a custom file format

so gotta make use of C++ as C# bitfields are not supported

[gleaming burrow]

https://hatebin.com/bmmzrssdic

[rose stream]

if they are then I did have to make use of enums and that is a pretty pain

[rugged spear]

iirc char** can be marshalled as new char[] { 'a', 'b', 'c' }

[rose stream]

and if I am to call char** in C#
how would I do that

[void basalt]

you would use the byte type

[rose stream]

i once used a marshal where I gave only string [] as input and it worked

but forgot how?

[void basalt]

chars are two different sizes between C++ and C#

byte**

[rugged spear]

actually yeah that's correct, definitely use the byte type (in c#)

[void basalt]

you'll need to enable unsafe code

and mark the functions as unsafe

[rose stream]

byte is 8 bits
where in order to define the header of the ogg packet
you need 8 bits or 1 byte
3 bits for size
4 bits for something i forgot
1 bit for a flag

[swift falcon]

is there an easy way to make a list "readonly", like anything can see the list and its contents, but are unable to use List.Add() and other methods like that ?

[rugged spear]

char in c++ is (usually) an 8-bit "character" otherwise known as a byte in c#

[void basalt]

What's the problem?

yeah chars in c# are 2 bytes

[rugged spear]

Yeah don't confuse c++ char with c# char

[rose stream]

if taken a look into C++
char holds 8 bits

[void basalt]

right

so use the byte type in c#

[lean sail]

just make it private, then use a property or function so other things can see it

[rose stream]

how am I supposed to take a uint type and convert it to 3 bit uint

like unsigned int i : 3;

[void basalt]

bit shifting

[rose stream]

i know about bit shifting but I am pretty noob in case of unmanaged memory in C#

better let me be my way

anyways thx for the help

[rugged spear]

what are the C++ method arguments

[rose stream]

"path to ogg file" "loop start points" "loop end points" "path to save the encoded file"

pretty dirty implemented but works the best for me

also wouldnt
fprintf(stderr, "Error: could not open input file\n");

cause unity to crash?

[void basalt]

invalid memory accesses will cause unity to silently crash

[rose stream]

🥲

now i get it why unity crashed last time

i thought fprintf is present everywhere
so it wouldnt crash

would this work in android
FILE* infile = fopen(argv[1], "rb");

[rugged spear]

im fairly certain in this case you need to use the library directly if you want to interop between c#/cpp (so implement the ConvertFSB method using a feature called Platform Invoke.) I have a feeling you maybe want to simply pipe stdin/stdout using https://learn.microsoft.com/en-us/dotnet/api/system.diagnostics.process?view=net-7.0

[rose stream]

let me have a look at it

[rose stream]

I am using for android
not pc
otherwise I could simply make use of a command line application working behind

[rugged spear]

Why don't you just use a library that already handles this for you? Such as https://github.com/SteveLillis/.NET-Ogg-Vorbis-Encoder

[rose stream]

i need decoder

[rugged spear]

https://github.com/NVorbis/NVorbis

[rose stream]

with crc32 packets
and raw vorbis packets
header sizes and linked lists
those decoders simply dont reveal that much

[void basalt]

Why do you need this exact format?

[rose stream]

to create a replica of fsb5 format
like you know
FSBank is supported for windows only
i am trying to write something that replicates it
FMOD Studio only takes input of fsb4 and fsb5 files
in unity fsb5 is the output of every audio file
with compression format vorbis
as vorbis is kindda used everywhere
so anyone can dynamically make a load of .ogg or .wav file and convert it to .fsb5
then make use of it in Fmod studio

my goal is android,linux and mac

[rugged spear]

If you want to write your own C# bindings for the library, you'll have to first build the C++ library for your target architecture (for example android could be maybe AArch64/ARM64)

[rose stream]

already did

for ARM32

[rugged spear]

And you're using the correct native library for your testing?

[rose stream]

yep

ogg and vorbis static android libraries compiled with android studio using jni

not done by me
found on github

[rugged spear]

Have you thought about writing a test app (in C#) before messing with it in Unity?

[rose stream]

yeah it works

but I am going to try it again one more time

[rugged spear]

Actually can you post a pic of the inspector for the native lib?

in unity

[rose stream]

dont worry
i will make it open source once its completed
all the code
compiled libraries
unity project and bindings

for both android and pc

then you can have a look

[rugged spear]

im more concerned about the import settings or whatever it's called

[rose stream]

in case of the import setting
you need to clarify the processor
or architecture for which the library is built
if its build for x86 android
then in the architecture type
select x86
make a call and it works

make sure its in different folders and architecture type is defined otherwise unity wont build and generate an error with 2 libraries with same name

[rugged spear]

okay so if you understand that then my next question is if this (reply) is the error you're having

[rose stream]

idk
i think it was due to something else
cuz fprintf is defined already to C++
but as the memory is not given
so it might cause error
but shouldnt as every application even if its GUI
its also command line

gimme 30 minutes so I can finalize things

[rugged spear]

okay so try debugging by another means. don't print to stderr (maybe stdout) or simply just write to a file using something like std::ofstream

Wait how are you invoking the method in c# first of all

[rose stream]

android file system is pretty fucked up
i can just return an integer
the integer would be an enum integer from which I can get the error in C#
not a problem for me

[rose stream]

dont mind but let me finalize things first then I will share the link with you🙂

[soft shard]

Im looking over some of Unity's code for the "new" input system rebinds, they have var partName = default(string);, I understand default(T) is useful when you dont know what default value T might accept (for example, you cant make a int null, or set an Object/class to 0), though is there maybe a micro-performance reason why Unity would choose to use default(string) specifically instead of string.Empty or just "", or is it just a convention/good practice?

[rose stream]

object/class is 0
the memory is managed by the CLI

that,s why you cant

[fervent furnace]

@carmine orbit was there anyone answer you yet? I will not call findobjectsss in every update, if the number of gameobjects is static i will call it in awake or start only else i will consider object pool

[soft shard]

Well I understand why you cant set a class to 0, cause its not a numeric type, I was more wondering why Unity would choose to use default(string) instead of string.Empty or just "", since in this case "T" is string, and I dont see a reason why someone might want to default a string in this way as oppose to the others

[rose stream]

😑

from 0 i meant total null

NULL

0

[fervent furnace]

0 mans nothing is allocated

[rugged spear]

The reason you can't set int to null is because it's a struct, and structs are value-types which apparently can't be null

[void basalt]

correct

[rose stream]

yep

[fervent furnace]

Null string means you have to allocate a char* for one byte and remember its capacity and size

[rose stream]

yea
but in case of unmanaged
you will need Marshal.AllocHgGlobal to do so

[soft shard]

So default(string) allocates nothing, and string.Empty and "" would allocate 1 char*?

[rose stream]

it just allocates the memory to the class

remember CLI

in C# the memory is managed by the CLI

[rugged spear]

To answer your question I don't think you need to worry about performance in this case

[soft shard]

Well im just curios why a programmer might choose to say var someString = default(string); over just saying var someString = string.Empty; or var someString = "";, if im understanding correctly, the latter two ways allocate some memory, while the first way doesnt allocate at all? Or am I misunderstanding what your saying?

[fervent furnace]

Oh i forgot string in c# is immutable so you probably need a char* and size only

[rose stream]

simply put
a string is like a char[][]
arrays always use 1 byte to store their size
even if its size is zero
if it is not used
then the char[][] will be unassigned and the compiler generates an error

you just cant do a string null

but yeah
you can do the null to a pointer as the size of the pointer or stacks is not defined

[rugged spear]

In C# you can set a string to null, because it's a class (reference type)

[rose stream]

wait
what?

then I am forgetting something

fuck i am out

[soft shard]

O.o

[rugged spear]

It's basically saying this reference points to nothing. The same as nullptr in cpp iirc

[rose stream]

ok leave the topic by saying
performance wont be affected

its eating brain now

[rugged spear]

"" != null

it's just empty

[fervent furnace]

“” is Equivalent to a ptr[0]=0 you need a byte to store this “0”

[rose stream]

i think I already told that

[soft shard]

Ah ok, I think I understand what you mean now, that convo did help after re-reading it a few times, thanks - it was some Unity code I saw im using as reference for rebinding, so was just curios, though a single byte doesnt sound like something worth micro-optimizing in production anyway

[dawn nebula]

How often do you guys used UnityEvents? I use them pretty prolifically to bind my prefabs together.

[rose stream]

memory is something that takes months to understand
took me 6 months to understand how computer memory worked

[rose stream]

🙂 thanks for wasting time

[rugged spear]

Exactly, which means it's a valid string, it's just empty.

[dawn nebula]

who cares about memory when you have garbage collection? 🙃

[rose stream]

still you need to learn it
I failed in my exams due to this

i still remember it

[soft shard]

I think curiosity is time well spent, you learn something new, so thank you for teaching me something new 🙂

[rose stream]

is armaebiv7a simply ARM32

[rugged spear]

yeah, it's a non-issue essentially

[rose stream]

?

[rugged spear]

garbage collection can be very annoying and also very slow in certain cases

[rose stream]

??

[dawn nebula]

I know, I was joking.

Memory should always be in mind.

[rugged spear]

it doesn't "just collect garbage" it also moves memory around at will whenever it wants to

oh okay sorry 😄

[rose stream]

looks like a dictator

[rugged spear]

it is 😛

[rose stream]

lol

[dawn nebula]

yep

[rose stream]

it did be a pity if someone can tell me is armaebiv7a simply arm32 or arm64

[dawn nebula]

How often do you guys use UnityEvents? I use them pretty prolifically to bind my prefabs together.

[rose stream]

never heard about it

[dawn nebula]

_>

[rose stream]

anyone guess my age?

[rugged spear]

To me UnityEvents are just a cool way for Unity to serialize traditional c# events but I don't use them very often

[soft shard]

I use them if im building a script for a designer who would find it easier to hook logic through the inspector, though more often I tend to use System.Action or create my own Delegate and hook everything up in OnEnable/OnDisable, respectively

[rugged spear]

I tend to stay towards the latter as well

[lean sail]

I dont see why you would really use it to bind prefabs, I just use it for stuff thats supposed to happen in scene. Like a pressure plate triggering a specific door = unity event. That way I can visually know which door i am selecting

Doing it through regular c# events is kinda weird imo

[rugged spear]

Yeah I think in terms of performance/usability it's more of a visual thing(able to be serialized in the inspector I believe) but it's essentially the same concept as regular c# events

maybe I'm thinking about UnityAction actually, I think that's literally the same as System.Action

[soft shard]

I do find it a little odd that typically youd create a empty UnityEvent class so it can be serialized, and just an empty class in the project seems like a weird concept to me

[lean sail]

🤷‍♂️ sometimes things just need to be setup in scene

[dawn nebula]

huh?

[lean sail]

its weirder to have my door for example, know about which pressure plate its trying to react to. Or weird to have another system entirely hook things up

[dawn nebula]

if you do something like public UnityEvent gameEvent in a monobehaviour it'll appear in the inspector automatically

[soft shard]

Maybe im thinking of something else, or ones that require params, I remember setting up a event for basically turning Physics.XCast into serialized events in the inspector, and had to do something like this to show up

public class SomeScript : Mono
{
public RaycastEvent onRaycastEnter;
}

public class RaycastEvent : UnityEvent {}

[lean sail]

I dont really know what the empty class thing meant either now that i read this

[rugged spear]

I feel like it's a more streamlined SendMessage feature with some added benefits

and drawbacks i think

[lean sail]

i still dont get the point of using it to bind prefabs, but it definitely has its uses otherwise

[rugged spear]

it definitely has its uses yeah, probably just a preference type of thing

[dawn nebula]

UnityEvents have a generic version that allow you to define the input type.

So like public UnityEvent<float> onTickEvent allows you to call any public parameterless function, or any function that takes in a float.

from the inspector

It gives you the same functionality you see with Unity's button or toggle component.

or those TextMeshPro unity events

[rugged spear]

or regular c# events, just with the added bonus of being able to manipulate it in the inspector

[dawn nebula]

yes

but that's BIG

[rugged spear]

true

it's probably just that they had to make their own custom implementation to add some magic "under the hood" to be able to serialize everything properly in the inspector

[dawn nebula]

Separate question.

Imagine you had collectable drops.

Like money or items or whatever.

Let's say you sort of expect a lot of them on the screen at once.

And when the player gets close, the collectable flies over to them.

Would you give the player some trigger collider that interacts with collectables and tells them to fly to them.

Or would you give each collectable a trigger that waits for the player.

[lean sail]

if only the player can pick them up, id go with it maybe on the player

thats a lot less trigger colliders

[dawn nebula]

ya the logic is... having it on the player gives less control, but is more performant

[lean sail]

there becomes a point where writing scalable systems is just not worth it

you could make every system as scalable, adjustable, whateverable as possible. But if you wont ever expand on it then no point worrying about it

you could give that same trigger and script to anything else that can pickup items too

[rugged spear]

wouldn't you still need to give each collectable a collider(trigger) so that the player trigger can detect if it's intersecting with a collectable? or am i misunderstanding

[dawn nebula]

well the collectables need a normal collider so they dont fall through the floor and shit

[rugged spear]

oh yeah true 😆

[lean sail]

thats what i was assuming too, i imagine there wouldnt be a massive performance hit anywyas unless you have a ton of items on the floor

but at that point, the amount of game objects would be worse than the trigger lol

[rugged spear]

I think the logical solution would be to have a single trigger on the player then because otherwise you'd need a collider for actual physics collisions and then wouldn't you need a second one (per collectable) that's a trigger? I forget if triggers still have normal collisions or not 😭

[lean sail]

Yes u would need both

The only scenario I can think of for putting the trigger on the object would be if the object is unique, or interacts with anything/anyone.
You wouldnt want your player to have a trigger for items, then another for idk opening a door when you are close

Which is a lot of scenarios I guess, idk why I said only

For example I have a cube which dissolves when the player comes close, it has a trigger on the cube itself. No need for the player to do this behaviour, so the script is on the cube

[rugged spear]

so wouldn't having both a normal collider and a trigger collider on each collectable item be like O(n) more expensive?

[lean sail]

Calling it O(n) sounds weird for number of triggers but yes. Which is why I agree to put it on the player in this case

[dawn nebula]

I mean if the player is chilling on its own physics layer and you just have a bunch of triggers listening for that one collider, it's pretty whatever.

Cost wise.

[rugged spear]

yeah i thought so too i just couldn't think of a better way of explaining my train of thought lol

[lean sail]

If it's one object it doesnt matter what you put it on, but depending on the use case sometimes it makes more sense for it to be on the object or player.
Like a ship opens up when you come near, put it on the ship. Even if theres multiple ships at least they can have their own events and whatnot
You pickup an object by being near, put it on the player. But in this case theres obviously multiple objects.

Even tho both are essentially the same, check if the player is within range

[rugged spear]

You could theoretically use Physics.SphereCast too but I'm not sure how expensive that is, maybe less such if you're only targetting specific layers but I can only assume it's fairly high compared to having the physics system detect intersections with triggers

[lean sail]

Every object on the floor too will basically have the same behaviour. If you want different behaviour it can just inherit from IPickupable (idk maybe name it better) and define it's own implementation

[rose stream]

my gradle build failed

any helps?

[ashen yoke]

should be roughly the same if its non alloc version

[rose stream]

it says 'android.enableR8=false' is deprecated.

i had this error before as well
like a year ago
now i forgot how to fix it

any helps

[rugged spear]

This would also alleviate the need for 2 colliders(1 normal, one trigger) per collectable. I think...

You'd only need 1 collider per collectable

[dawn nebula]

To give a better idea for the pickup I'm imagining. Think of the XP bits from those Vampire Survivor games.

Lots of them.

These blue crystal thingies.

[ashen yoke]

if you have a choice between maintaining giant amount of in scene colliders, triggers whatever and a simple straight forward solution out of scene graph that is slightly more expensive, chose the latter

treat performance costs as balancing act, is it reasonable to exchange performance for clean architecture?

[rugged spear]

My opinion: fuck around and find out 😄

[dawn nebula]

Step 1) Fuck Around
Step 2) Find Out

[ashen yoke]

thats an interesting example

because if you rely on physics for that, youd end up with large amounts of game objects in the graph just to have colliders

that cost can be alleviated with some simple spatial structure, probably

so you dont have to have gameobjects

[rugged spear]

AABB isn't terribly expensive either if that's a possibility

[ashen yoke]

still need spatial acceleration to narrow down

a simple grid would do miracles there

[rugged spear]

definitely with that amount of objects

[ashen yoke]

spatial hash would work with maps of any size

[rugged spear]

especially since they seem to be clustered together so tightly

[dawn nebula]

I doubt those games have insane optimizations beyond pooling

but maybe im wrong

[ashen yoke]

afaik its not made in unity

so it by default doesnt have associated gameobject/scene graph overhead

but it 100% has acceleration structure

there is no way around it

[lean sail]

you would probably need ecs tho for the amount of enemies it has

[dawn nebula]

what do you mean by acceleration structure?

[rugged spear]

I'm under the impression that ECS could be "the way" to do such a thing, but you could theoretically get by (probably fairly well) with the various techniques mentioned above

[ashen yoke]

any spatial structure that accelerates queries, quad/octree, grid/spatial hash, bvh etc

[lean sail]

the pickups yea,
the amount of enemies that vampire survivors has, probably not

actually idk how many enemies it has, ive only seen gameplay briefly where the screen was full

[rugged spear]

I've never seen the game, but I've seen some very impressive 3d work with ECS so I can only guess

[ashen yoke]

ecs is certainly good pick here, unity one will provide massive performance gains, but if you dont need it, like in case of vampires you can get away by simply looping a list of objects

there arent that much objects, and just looping them will work just fine

they also dont have any advanced ai

so you dont maintain 1000 bts

[dawn nebula]

Ai is literally find direction to target

go

[ashen yoke]

not even necessary

you can use flow field

one fill of the graph per frame and all enemies know direction to player by sampling direction vector of the cell they are in

almost zero cost per agent

[west lotus]

Why every frame. Time slicing it based on the distance to player would be even better

[ashen yoke]

yeah you can tick it, but even every frame it would have small fraction of cost

compared to computing paths

[rugged spear]

There are a number of optimizations that can be done definitely, the real question is whether they need and/or are willing to implement them

[dawn nebula]

Just want to mention

not making Vampire Survivor game

just gave a sorta extreme example for the number of drops on the ground

something like uuuuh

Enter the Gungeon is probably the best comparison?

Bullet Hell-y

lots of projectiles

[novel kayak]

fun fact,i work on a bullet haven game also,like vamp s ,brotato,etc.

[ashen yoke]

https://github.com/jongallant/Unity-Bullet-Hell

remembered this

[rugged spear]

Personally I would say only optimize when needed, otherwise you're probably wasting your time on something that probably isn't even an issue to begin with

Most modern hardware will be able to cope just fine

It's definitely another story if you're specifically targeting older hardware, but you can only find out one way or another

[ashen yoke]

i agree, KISS it first

see if it works as is

Can someone help me with the Load Method using System.Runtime.Serialization.Formatters.Binary

I don't know how to display the items.I'm sure that the items are saved because i've looked into the binary file.

So the problem is that the RetriveItemList() is always log (Item list is empty)

(The materials are displayed correctly)

[rugged spear]

I definitely understand the natural feeling to write "the best, highly optimized"™️ code that will run on a potato, but today most computers can run insanely fast and unless it becomes an issue down the road then just don't worry about it until you need to.

[rugged spear]

I don't see anywhere in your screenshots that rewards.itemList is ever assigned?

[novel kayak]

in the RetrieveItemList() function,first photo

[rugged spear]

That's a local variable in the method that is assigned from rewards.itemList, where is rewards.itemList assigned?

[novel kayak]

in the Rewards script

[rugged spear]

where do you populate the rewards.itemList variable

So where is the code that loads the itemList from the file

[novel kayak]

First image sent,is loading materials(which is working) but cant load the items correctly

[rugged spear]

I see you do rewards.materials = loadedData.materials; but you never do rewards.itemList = loadedData.itemList in the LoadData() method

private void RetrieveItemList(List<Item> itemList)
RetrieveItemList(loadedData.itemList)

[novel kayak]

Love you

[rugged spear]

in the RetrieveItemList method, remove the List<Item> itemList = rewards.itemList; line

[rugged spear]

it works now?

[novel kayak]

Y

[rugged spear]

okay cool

I was trying to help you clean up your code but as long as it works that's great

[hot torrent]

this code just crashed unity

[main tree]

Hello, how can I use SetActive in Photon, to hide a object for both players? I tried this way but it gives an error:

GameObject nesne = liste[0];
PhotonView photonView = GetComponent<PhotonView>();
photonView.RPC("gizle", RpcTarget.AllBuffered, nesne)

[PunRPC]
    void gizle(GameObject nesne)
    {
        nesne.SetActive(false);
    }```

The error:
``Exception: Write failed. Custom type not found: UnityEngine.GameObject``

I'm sure that "nesne" variable isn't null. I checked it.

[hot torrent]

you can´t send custom classes thru Photon. Also #archived-networking

[fervent furnace]

i(t)=i(t-1)*something
=i(0)^(t) and something<1
so i will never reach zero

[hot torrent]

mhm...
gotcha!

ty

[main tree]

Okey, sorry and thanks!

[hot torrent]

No worries!

[fervent furnace]

oh i miss read, the correct formula should be:
i(iteration)=i(iteration-1)-i(iteration-1)*something
i(iteration)=i(iteration-1)*(1-something)<= this thing also < 1 and > 0
but the result is still the same, i never reach 0

[hot torrent]

I found a different solution anyways, thanks for tha explenation!

[wicked kiln]

hello guys im doing an isometric game and i wrote a code to generate tiles based on Perlin noice and i have an issue with the tiles they do not generate in a flat surface its like they have different elevation does anybody know how to fix it https://paste.ofcode.org/Gf74rYbaqSY58v55hnBuU3

[steady moat]

Use z instead of y ?

[rugged wedge]

Hey, I got a bit stuck here so I figured I'll ask here and see if I could get some response.
My goal is to have the planet rotate constantly, and affect the ball so it rotates the same speed as the planet. But the catch is I don't want the ball to impact the planet's rotation when it's rolling over the surface of the planet. Any ideas?

[wicked kiln]

its 2d no z

[steady moat]

Is it flat 2D ?

Like topdown ?

[wicked kiln]

its isometric its flat but has the illusion that its not

[steady moat]

So, the gound is z-x ?

Oh, ok nvm I understand.

Do you use a single renderer ?

Because it seem to me that it render group of tiles by group of tiles

Maybe this would help: https://docs.unity3d.com/Manual/class-TilemapRenderer.html#:~:text=performance with Tilemap.-,Individual,-The Renderer renders

(That being said, you might want to find an alternative as performance will tank)

[wicked kiln]

i render them individully because its a small world right now but in the future this must change

[steady moat]

So, you are saying it did not help ?

[wicked kiln]

yes i already use individual rendering

thanks for the try

[steady moat]

Alright, I do not really know how to fix the issue. However, I am pretty sure this is about rendering order. (And not height)

Maybe try to read: https://docs.unity3d.com/Manual/Tilemap-Isometric.html

[wicked kiln]

okay man thanks a lot

[wispy nacelle]

I have a scriptable object in my project. I included it into an assetbundle and also had a reference to it in a scene, and 2 instances of it were created after the game starts

[gray mural]

I wonder if anyone knows one of these things:

• How to prevent textInfo.lineCount from being 0 , when text is stringEmpty. So it should always be 1
• How to get TMP_LineInfo and TMP_CharacterInfo even when textInfo.lineCount == 0

[steady moat]

Because you have it in the assetbundle and you have it in a scene. (Usually, you also bundle your scene)

[wispy nacelle]

I'm just using the asset bundle as a way to force load some of my assets

[steady moat]

What do you mean ? Because if you have a reference in a scene and in an asset bundle it will definitly be duplicated.

Maybe there is something else you can do ?

[wispy nacelle]

Hmmm

[steady moat]

Instead of using AssetBundle (If you dont want)

I mean, what is your issue.

I might know something

[wispy nacelle]

If I don't use Asset Bundle then it may not have been loaded when I need it

[steady moat]

Depends

Asset Bundle is the surest way to do it.

You could, by example. Do Resource.Load(); https://docs.unity3d.com/ScriptReference/Resources.Load.html

[wispy nacelle]

My personal problem with Resource is that it requires me to place all the assets that has to be loaded in a certain foler

folder

[steady moat]

You can have multiple Resource Folder

[wispy nacelle]

I'm well aware of that

[steady moat]

Also, resource is not recommanded.

However, it can get the jobs done.

[wispy nacelle]

They are the assets that I need anytime

[steady moat]

Not an issue with Resource

I'm not saying that you should, I'm just presenting alternative.

• Bundle your Scene
• Remove your Reference from your Scene
• Remove the Asset from the Bundle
• Use Resources

[wispy nacelle]

Thanks

[steady moat]

You cannot have at the same time, a reference to a SO in the scene (Not Bundled) and a reference to the same SO in an AssetBundle without duplicate.

[wispy nacelle]

Probably I should make something that I can drag my SO in and store its name

[wispy nacelle]

Thanks

[signal spade]

I have been working on procedurally generating a large world using Unity terrains. Most things are working successful except terrain stitching. It works for the most part, but in some cases (typically on higher heights) the terrain will not snap together and ends up folding. I am looping through heightmap values and connecting the first row of the new terrain to the last row of the top terrain and the first column of a new terrain to the last column of the left terrain. What I had found was it seems like after about 40m in height, the snapping starts. I added some controls to clamp the heights (not 100% working yet), but I can't fathom that this is the solution. There has to be terrains that have been developed before with wider height gaps. What am I missing here? Is it just not possible?

(Please ignore the ugliness as this is just solid color materials currently and no refined procedural noise)

[thick stratus]

    public void groundCheck()
    {
        RaycastHit hit;
        if (Physics.Raycast(transform.position, Vector3.down, out hit, groundcheckDistance, ground))
        {
            isGrounded = true;
        }
        else
        {
            isGrounded = false;
        }
    }

For some reason this not detecting my ground layer when on the layer, if i change the distance to around 5 it detects the layer but when i jump it detects the layer for too long allowing like 10-15 jumps

[wind palm]

What is ground?

[thick stratus]

a public layermask

ive assigned it in the inspector the ground layer

[dry bronze]

I need some help regarding transform.LookAt.I basically have a planetary system with orbits and then the player would be in a sector in that system and the code is supposed to find where the stars / planets are in relation to the sector and display them as a sort of "physicalized skybox"
however, sometimes this fails and projects the planet and star at completely false positions

            {
                _planetCParents[i].transform.rotation = Quaternion.LookRotation((GlobalManager.Instance.CSSI._celestialBodies[i].transform.position - transform.position), transform.up);
                //_planetCParents[i].transform.rotation = _rotationObj.transform.rotation;
                _planetCObjs[i].transform.localPosition = new Vector3(_planetCObjs[i].transform.localPosition.x, _planetCObjs[i].transform.localPosition.y, Vector3.Magnitude(transform.position - GlobalManager.Instance.CSSI._celestialBodies[i].transform.position) * 1000 + 10000);
            }

this is the relevant code (ignore the second line, that's commented out cause it's a relic from an attempted fix that didn't work)

[wind palm]

Depending where your transform.position is, you could be starting your raycast under the terrain.

I've seen people using sphere cast in the past to circumvent this

[dry bronze]

the code points an object (_planetCParents[i]) at the relevant planet ([GlobalManager.Instance.CSSI._celestialBodies[i]) by subtracting that planet's position minus the sector's position, then use transform.LookAt on that

it does work fine usually

but eventually it breaks for whatever reason

[thick stratus]

the script is on my player model and thats def above the terrain

i could try a sphere cast but every other raycast type ive tried has this issue

[wind palm]

Unity use a combination of raycast and spherecast on their character controller.

If you want to learn from them I can provide a link to their code for it?

[latent latch]

#archived-shaders

[fading trail]

oh thanks

[swift falcon]

Is there a better way of doing this? It feels pretty verbose but I can't find anything else that works in a similar way

    [System.Serializable]
    public struct Message
    {
        public float Speed;

        public float GetSpeed => Speed == 0 ? DEFAULTSPEED : Speed;
    }

    const float DEFAULT_SPEED = 0.025f;```
I want to make it so:
The struct has a default value for Speed 
If Speed is changed in the inspector then that value is used instead

Like each variable now uses up 3 lines for itself, the property and the const

        public float GetSpeed => Speed == 0 ? DEFAULT_SPEED : Speed;
        public float GetPuncMult => PunctuationMult == 0 ? DEFAULT_PUNC_MULT : PunctuationMult;
        public string GetAudioClip => string.IsNullOrWhiteSpace(AudioClip) ? DEFAULT_AUDIO : AudioClip;```
Getting long. Not a big deal but I'm always trying to write the best code possible

I get an error when I do that, one sec

Yeah it asks me to make a contructor, so I do that and assign values. Then I get a different error about not being allowed have instance property or field initializers in structs

[somber nacelle]

yep that's not allowed until c# 10 which unity probably won't support until sometime next year at the earliest

[latent latch]

oh yeah I was actually just reading that

[swift falcon]

Alright so this is the best way until then?

Yeah alright I'll try that

[gray mural]

make struct serializator

private readonly float _defaultSpeed = .025f;

[System.Serializable]
public struct Message
{
    public float Speed;

    public Message(float Speed = _defaultSpeed)
    {
        this.Speed = Speed;
    }

    public float GetSpeed => Speed;
}

[swift falcon]

That seems even more verbose

[somber nacelle]

public Message(float Speed = _defaultSpeed)
well that's not valid

[twin hull]

no errors 🤔

[gray mural]

I don't think so

[somber nacelle]

default parameters have to be compile time constants, not just readonly and/or static. sure they could make it a constant but unity isn't going to be calling the parameterized constructor for the struct so it doesn't matter anyway. and you cannot define a parameterless ctor on a struct until c# 10

[somber nacelle]

sure that is valid. but simply using a readonly field from the containing object isn't

[swift falcon]

Mine is 3 lines per variable. Yours is also 3 lines + a constructor

Yeah true I guess, what's the benefits of that anyway

I'll only be assigning stuff in the inspector btw

[twin hull]

class just seems more appropriate for that, then

[gray mural]

did I just mess up the cs part or something else?

[gray mural]

with cs

just write "cs" after 3 '

and it gonna make your code colorful

[idle oxide]

So I tried making movement for my player. When I move right the code does exactly what I want, the speed caps out at MaxSpeed but when I move left the players velocity doesn't stop at maxSpeed and I really can't figure out why that happens. Thanks in advance!

private void Update(){
   horizontal = Input.GetAxisRaw("Horizontal");
}``````cs
private void FixedUpdate(){
   Debug.Log(rb.velocity.x);
   if (rb.velocity.x >= maxSpeed){
       rb.AddForce(new Vector2(horizontal * speed* (-0.1f), 0f), ForceMode2D.Impulse);
   }
   else{
       rb.AddForce(new Vector2(horizontal*speed, 0f), ForceMode2D.Impulse);
   } 
}```

better?

[gray mural]

perfect

[earnest gazelle]

How can I recognize the type of specific scriptable object assets in AssetPostprocessor?
AssetDatabase.LoadAssetAtPath ?
Should I get all assets and check them?

[gray mural]

of course, I does not stop, it should move in other direction 10 times slower

[idle oxide]

oh right I see the problem now!

Thank you

[gray mural]

maybe you should consider using this?

if (Mathf.Abs(rb.velocity.x) > maxSpeed)

Mathf.Abs returns absolute value of float

[wind palm]

If max speed is the max speed so is valid you probably can lose the =

[gray mural]

velocity can be both e.g. -200f and 200f, so Mathf.Abs always returns 200f
https://docs.unity3d.com/ScriptReference/Mathf.Abs.html

[idle oxide]

and I should add another if that checks if the velocity is positive or negative so it multiplies it by either -0.1 or 0.1

[gray mural]

why should you? What do you even need to achieve?

[gray mural]

yeah, maybe, doesn't matter so much though

[idle oxide]

basically I want the player to have an acceleration rate (speed) and the max speed it can reach (maxSpeed) and I don't want the player to loose all the momentum at once when the person stops pressing the direction keys

This code now works great!

private void FixedUpdate(){
    Debug.Log(rb.velocity.x);
    if (Mathf.Abs(rb.velocity.x) >= maxSpeed){
        if (rb.velocity.x > 0){
            rb.AddForce(new Vector2(horizontal * speed * (-0.1f), 0f), ForceMode2D.Impulse); 
        }
        else{
            rb.AddForce(new Vector2(horizontal * speed * 0.1f, 0f), ForceMode2D.Impulse);
        }
    }
    else{
        rb.AddForce(new Vector2(horizontal*speed, 0f), ForceMode2D.Impulse);
    }  
}```

[gray mural]

then you probably need to AddForce to player if their speed is still lower than maxSpeed (otherwise player's speed should be set to maxSpeed) and clamp their velocity

[idle oxide]

I didn't like the look of just setting the velocity to MaxSpeed so I did it the way shown above

[gray mural]

private void FixedUpdate()
{
    Vector2 force = new Vector2(horizontal * speed, 0f);

    if (Mathf.Abs(rb.velocity.x) < maxSpeed)
        rb.AddForce(force, ForceMode2D.Force);

    rb.velocity = new Vector2(Mathf.Clamp(rb.velocity.x, -maxSpeed, maxSpeed), rb.velocity.y);
}

[gray mural]

that's not what I mean

see in the example provided

I hope that works

https://docs.unity3d.com/ScriptReference/Mathf.Clamp.html

[idle oxide]

I get this error

[gray mural]

oh, no, forget

[gray mural]

Now that I got it to work this works absolutely perfectly! Thank you very much

[gray mural]

nice to hear, and that error was because you needed to set Rigidbody2D = new Vector(smth, smth), not its x or y values, my bad

[idle oxide]

Now my basic player controller is done! Now I move onto harder stuff lol

[random oak]

is it ok to have Reference type in a struct? how do I deal with storing a copy of the object

[somber nacelle]

copies of the struct will contain the same reference

[random oak]

If I make it null inside one of the struct will it affect the other structs?

[somber nacelle]

no

[random oak]

ok ty

[somber nacelle]

only copies of that instance of the struct will also contain null in the variable

[random oak]

perfect thx 🙏

[swift falcon]

This is a bit weird but is there a way to assign a variable from another class in the inspector? Or a way to write down the variable name as a string then at runtime find that variable based on the string?

I'm working on NPC logic and I'm trying to figure out ways to avoid making a unique script every time I want an NPC with different triggers/logic
I want NPCs to be able to check say whether the player is grounded. Or how high a timer on a manager is. Or other various things like that
Is this possible?

[fervent furnace]

when you copy the struct you just copy the reference (pointer) but the memory address pointed wont be copyed

sounds like design problem
you want to check some "value" of some object in run time then you must reference to that object unless that "value" is reference type then you copy the reference

[swift falcon]

Ok so like if I did it the slow way then I could end up with like 50 scripts:

NPC 1:
if (Player.Grounded)
PlayDialogue("Ground")

NPC 2:
if (TimeManager.Time > 5)
PlayDialogue("Its Time")

NPC 3:
if (TimeManager.Time > 10 && Player.Health > 2)
PlayDialogue("Its Also Time")

NPC 4:
if (Player.Dead || BoxCast(...).collider != null)
PlayDialogue("Fourth")

Like for almost every NPC I make it's a new script which sure is fine but if it can be avoided I'll jump at the chance

i will consider having a abstract parent class and has a static references to those objects needed to be checked and some static functions for checking those objects then for the scripts of each type of enemy just pick up the functions on base class they needed
