[zenith crown]

Using a variable i called Current speed

These

[polar acorn]

What about this

this is a bunch of variables on a different object, what does this have to do with the question

Do you have another canvas in front of this one?

And does this canvas have a GraphicRaycaster component?

[winter tinsel]

well first yes, but if i delete it the button is still not clickable?

ill check

[winter tinsel]

yes

should i change anything in it ?

[winter tinsel]

and even if, the button that doesnt work, its not under or over any button in the other canvas

[zenith crown]

Well im trying to use the MovementController to get the WASD input into a direction

that i then multiply

by the current speed

[polar acorn]

Okay, but what method do you intend to use to actually move something

[zenith crown]

and then move that way

[polar acorn]

Show the inspectors of the button and the canvas that the button is on

[zenith crown]

Lemme see in the tutorial cause im kind off using it to translate my code from godot into unity

[winter tinsel]

the canvas that the button is a child of right?

[polar acorn]

yes

[winter tinsel]

its a lil difficult cause they have alot of stuff

should i send each individually or is there something specific you need?

like as much info into one pic cause i cant get the full inspector in one

[zenith crown]

Idk he just used public CharacterController Controller; then proceeded to use Controller.Move(move * Current_Speed * DeltaTime)

[polar acorn]

I am just going to look for anything amiss. Send multiple pictures if you want

[polar acorn]

Okay, and did you do that?

[zenith crown]

Yes

[polar acorn]

Then why didn't you show that

[zenith crown]

You can see it here except that its before adding current speed and delta time

cause it didnt work without them

[winter tinsel]

first pic is parent, next 3 are button

[polar acorn]

"I did it exactly like the tutorial so why does theirs work and mine doesn't" counter:
Number of times it wasn't exactly like the tutorial: 171
Number of times it was exactly like the tutorial: 5
Number of times the code literally did not exist: 1
2022-07-19 to 2024-07-14

[zenith crown]

Now i did it

and it still didnt work

[polar acorn]

Did they name their script CharacterController in the tutorial

[zenith crown]

I now see the problem

[polar acorn]

Your button component is disabled

[zenith crown]

wow that is an embarassing mistake

holy

[winter tinsel]

w h a t

h o w

i havent touched it???

[winter tinsel]

are you kidding me???

how did that happen??

[polar acorn]

Misclick maybe?

[winter tinsel]

i literally havent touched it

no i havent opened it at all lmao

this is crazy

[grizzled gale]

Unitypackage file not opening sumthing error

[winter tinsel]

that was it

ugh

[zenith crown]

fixed that problem

[winter tinsel]

thanks

[zenith crown]

still doesnt work

its exactly like in the tutorial the code

[polar acorn]

Did they name their script CharacterController in the tutorial

[zenith crown]

Bro i literally changed it and its still the same

omd

one sec

Now it works

thank you man

im blind

[polar acorn]

I'm just glad that it wasn't something else because I was out of debugging options

[winter tinsel]

one last question, if i was to make a main menu, would that be a whole nother scene?

and while that scene is running, the other one with the actual game wont right?

[polar acorn]

It could be. There are many doors, Ed-Boy

[winter tinsel]

simplest one for right now

point is yes it can be

okay uh

[polar acorn]

Simplest is probably just a canvas you toggle

[winter tinsel]

ehh, rather not

[polar acorn]

but an additive scene is probably better for organizational purposes

[winter tinsel]

yes

and while that scene is running the actual game scene wont right?

the scene that has the game

[polar acorn]

If you change scenes, the scene that gets unloaded ceases to exist and every object in it is destroyed

You could use additive scene loading to have multiple scenes at once

[winter tinsel]

what if i change BACK to that scene?

does everything get reloaded?

[polar acorn]

You would be loading that scene from disk as it was defined in the inspector

[winter tinsel]

question, if i was to make a game with multiple indivually explorable areas that are big on their own

this would require mulitple scenes right?

[polar acorn]

Probably

[winter tinsel]

or atlesat it would be better with them

im just asking if itll work on build

like will it work if the base scene is the main menu and you load into the GAME scene ig

it changes to it ig

[lunar crater]

it was because charactercontroller, your script was a class inherited from monobehavior and charactercontroller, the component is also a class so they were causing conflict and i'm guessing your script is like a higher priority class

[sleek marten]

I'm having this UI overlapping issue and can't find a reliable fix

What do I do about this?

[modest dust]

Since this is a code channel, post the code related to the issue

If you're using a custom property drawer, then you probably didn't override GetPropertyHeight or made a mistake

Also #↕️┃editor-extensions

[sleek marten]

{
    [System.Serializable]
    public class Wave
    {
        public string Name;
        public Transform Enemy;
        public int Count;
        public float SpawnRate;
    }

    public Wave[] Waves;
}```

(I'm on 2021.3.4f1 as well)

[late compass]

hello , i have a list of Components i want to make foreach loop and then disable every component in the list in the foreach loop like this :

            foreach(Component componentcomp in NonNetComps)
            componentcomp.enabled = false;

but i get an error on enabled why i cant access it ?

[modest dust]

Do you have a custom property drawer for the Wave class?

[sleek marten]

like an editor script?

[modest dust]

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

[queen adder]

@sleek marten you don't have to serialize the second class like that?

You can just serialize the fields themselves

See if that fixes your issue

[modest dust]

The thing he does is perfectly valid

[queen adder]

Oh no I see what your doing my fault

[sleek marten]

I've never used one these before

[modest dust]

Try updating your unity editor version then

[queen adder]

What version of unity are you using?

[modest dust]

You're 36 versions behind the latest LTS version for 2021

[sleek marten]

That could be it

[sleek marten]

2021.3.4f1

[sleek marten]

are you saying to use something like 2022?

[modest dust]

Not necessarily

2021.3.40f1

You can try 2022 if you want, but backup your project

[desert plinth]

Is there a way to get the gizmo box to rotate with the game object? When I rotate the object that has the gizmo, the gizmo stays at the same orientation

[modest dust]

Pretty much backup your project every time you update your editor

[sleek marten]

I got like 8 versions of unity installed

I have .4f1 AND .40f1

[modest dust]

Are you using ALL 8 versions?

[sleek marten]

nope

[modest dust]

Then uninstall them

[sleek marten]

but everytime I start a group project they always want to use a different version

[sleek marten]

I'd love to

circumstances won't let me

[modest dust]

And how many group project are you in at once

[mint remnant]

@desert plinth if you can use a sphere instead of cube, no need to rotate it

[sleek marten]

uhhh 3 atm

plus a solo

[modest dust]

Then you can remove half of these versions

And politely ask others to use the latest LTS in the next projects

[desert plinth]

Yeah...could do that actually...thanks I guess

[sleek marten]

into the trash they go

I'll change to 40f1 and see how it goes

[lilac ocean]

say you create a class in script a, is it possible to create an instance of that class through script b?

[polar acorn]

Yes

[lilac ocean]

how?

[polar acorn]

new

Assuming the class in Script A isn't a MonoBehaviour

[lilac ocean]

ok yeah

[ionic zephyr]

Should I make my resources and my tools different ScriptableObject scripts?

or is it better to make an "item" scriptable object?

this is because I want my tools to have atributes like strength, durability

[short hazel]

You can make an abstract scriptable object, if your items have common properties (like a name, a rarity, etc.)

Then derive from it, for each different item type that has specific properties (a gun would have an initial magazine capacity, and armor would have strength)

[sleek marten]

That fixed it! thank you!

[hybrid tapir]

is there a way to run a script without play mode? i wanna change the text size of a button when the screen resolution changes. (in this case when i drag the editor window from my 1080p monitor to my 720p tv) i finally figured out how the anchors work.

[short hazel]

You may not need to, you can check the "Auto font size" in the button's underlying TextMeshPro Text component

[hybrid tapir]

oh

[short hazel]

That way it will adapt to the container (the button) size

[hybrid tapir]

thank you

why does it make the text bigger when i switch screens

thats literally the opposite of what i want to happen

-_-

[ionic zephyr]

Can I rename all the appeareances of a CLASS name?

I know you can with variables but what about classes?

[slender nymph]

use the refactoring tools to do so

[short hazel]

Same way as renaming variables. The keybind depends on which code editor you're using

[ionic zephyr]

Visual Studio

(not code)

[short hazel]

With the caret (blinking text edition cursor) over the name, hit Ctrl + R twice to begin the rename operation

[ionic zephyr]

I get an error

It says I can´t rename this

[short hazel]

Make sure the caret is over the class name

Not the mouse cursor, the caret

[ionic zephyr]

still not working

[slender nymph]

are you doing it from the class or from some other file?

[short hazel]

Show a screenshot of what you're doing

[ionic zephyr]

other file

[slender nymph]

yeah so that's likely the problem

[ionic zephyr]

oh okay, it is

[lilac ocean]

Atom is a class and atoms is a List<Atom>, when i run foreach(class Atom in atoms) it gives me a ton of errors, and when i run foreach(Atom in List<Atom> atoms) it doesn't change anything

[short hazel]

First, configure VS Code so it highlights errors for you

!vscode

[eternal falcon]

Visual Studio Code guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

i followed the steps

its not showing any errors tho in vscode

[tame jolt]

how should i add a momentum system while using character controller

[eager spindle]

momentum?

like the player walks for a while and takes time to stop?

you can access characterController's velocity, such that when input keys are released you can keep moving the player based on velocity

[tame jolt]

thanks

[flint python]

How can i get the correct x,y of the rotated triangle?

[slender nymph]

transform.TransformPoint

and pass in the local position of (0, t)

[limber robin]

I’m pretty new to Unity/c# and every time I try to make a simple game, I get stuck for hours trying to figure out why my code doesn’t work, often to no avail. Is it better to just abandon my work and start over, or try to stick it out even when feeling totally lost and helpless?

[raw token]

Stick it out and ask for help. Software development is largely a process of breaking and fixing things - the time you invest in figuring out a problem and solving it will pay dividends later. You'll start to avoid creating the same bugs, and you'll get better at hunting and killing them.

[eager spindle]

stick to it. debugging is a very important part of programming

[eager spindle]

dumb way is to transform.rotatearound

[raw token]

As an afterthought, when you're feeling totally lost or overwhelmed, sometimes it can help to switch scopes for a while. Instead of dropping the project, pivot to focusing on a different aspect of it for a bit. Maybe even a totally new scene to explore some other feature

[limber robin]

Okay thanks. I guess I’ll post one of my questions here in case someone knows: For some reason when I run my game and click the mouse button, my objects’ gravity scale changes. I used to have a code that did that so I disabled the code, removed the script component, and then even deleted the code, none of which worked. This wasn’t a problem until I changed my GameObject into a prefab, does that have anything to do with it?

[languid spire]

If you are having trouble figuring out what your code is doing I would suggest learning to use the debugger then you can step through your code line by line and see what it does exactly

[stuck palm]

these replay files are massive man is there any way i can compress them at all?

[raw token]

Apply compression :P

[stuck palm]

how can i do that?

[raw token]

I'm not entirely sure - I'm looking into it now, out of curiousity. But it would seem reasonable to me to zip/gzip/7zip them

[stuck palm]

28mb per replay is wild

thats with like 4 people for a 6 minute match

just a bunch of input data

[rich adder]

Anotber reson saving binary data is better suited. filesize should be a lot smaller

[steep rose]

this code gives me my speed at which my rigidbody is moving, is there any way to split this in 2 to check what speed my forward/backward, left/right speeds are?

        var vel = rb.velocity;      //to get a Vector3 representation of the velocity
        speed = vel.magnitude;

[rich adder]

Just get the Z and X no?

[slender nymph]

each axis is already the speed it is moving along that axis

[steep rose]

that works but i need it to not go in the negatives

[slender nymph]

then get its absolute value

[steep rose]

can i find that by using mathF.abs()?

yup that works ty guys 👍

[sharp abyss]

any ideas for how can I make my ragdoll take steps manually and make walking a little bit a skill issue in my game?

is there a way to make something happen when you release getkey? because getkeyup only works when you press and instantly release.

[rich adder]

how else would you want ?

GetKeyUp works usually

if you mean you want some actions to happen across time after release, then enable a bool, put it update if statement

in this loop, i am running through a list of instances of the Atom class. i want to add the electrons and protons variables of all the instances of the Atom class within this list to the totalElectrons and totalProtons variables. im doing this through a foreach loop, but am getting this error

[rich adder]

nvm

[lilac ocean]

ok

[rich adder]

you need to use the instance

since those are not static

[lilac ocean]

wym?

[rich adder]

do you know what at instance is ?

atom would be the instance

[lilac ocean]

yes, but how to i count up all the electrons/protons from all the instances in my list?

using "the instance"?

[rich adder]

you keep reassinigng new value each iteration

if you want to add them up you use +=
oh nvm I see your doing var + var

share !code properly cause its hard to paste line of code to show you

you are using the CLASS

thats the blueprint

[lilac ocean]

my bad

[raw token]

It sounds like you would generally need to include the relevant dlls for a compression library to your project (possibly multiple libraries to support multiple target platforms), after which you could utilize whatever functionality they offer.

I see Unity also provides a com.unity.sharp-zip-lib package wrapping SharpZipLib - it looks like to compress you'd use a StreamWriter to write your JSON string to a MemoryStream, run that through one of the library's compression interfaces, and write the output stream to disk... And for decompression, I would think the same in reverse, but starting with a FileStream and the corresponding decompression method instead.

Depending on how large a replay can become, it might also be necessary to perform this work in a separate thread to avoid hanging the application 😬

It looks like there are also a number of assets available on the store which could tackle the problem.

This is all somewhat out of my wheelhouse and I reckon that I'm overlooking important things and alternatives. I lean towards navarone's suggestion of using binary serialization first. And then maybe applying compression on top of that, if necessary.

[stuck palm]

Interesting! thanks for your analysis. yeah, hanging is an issue, because my game freezes for like 3 seconds whenever it ends trying to save the file

[short hazel]

The built-in classes in System.IO.Compression should also work in Unity

And for the game freezing, offload the task to another thread or use the async methods

[queen adder]

Hello I am trying to get a button to change to a bool to true then to false alternating on each click is there a way to do that

[short hazel]

Sure thing, in the button's click handler method: val = !val; where val is your bool variable you want to toggle

"val is now equals to the opposite value of val", which effectively toggles the value each time this line is executed

[steep rose]

this is suppose to clamp the vector right? my character accelerates fast so im limiting speed but it doesnt clamp it

                xvel = Mathf.Clamp(xvel, -maxairspeed, maxairspeed);
                rb.velocity = new Vector3(xvel, rb.velocity.y, rb.velocity.z);

am i doing something wrong?

[queen adder]

Okay thank you will this change each time or only once?

[short hazel]

Each time this line is executed

[rich adder]

this only clamps the x value

[steep rose]

yeah thats what i want

but it doesnt

[queen adder]

Okay so it will swap each time

[short hazel]

If that line is put in the button's click function, yes

[rich adder]

might have to show more of the script. hard to say from this alone

[queen adder]

Yep it is thank you very much

[steep rose]

here are the xvel values

        var xvel = rb.velocity.x;
        var zvel = rb.velocity.z;

        speedX = Mathf.Abs(xvel);
        speedZ = Mathf.Abs(zvel);

i dont know if its because my character accelerates to fast but that shouldnt be a problem for clamping
i dont think

[queen adder]

public void onClickPanelShowDispear()
{
isPanelShown = !false;
}

When this method is ran will isPanelShown = true

[short hazel]

Well yes, NOT false is true

[rich adder]

why not just write = true

[short hazel]

Scroll back up at my example

[raw token]

The clamp will clamp. Have you verified that rb.velocity.x is definitively exceeding maxairspeed? In order to do so consistently, something else would have to be affecting rb.velocity after the code you shared above

[queen adder]

bcs I want it to swap when the method is ran

[rich adder]

if you want a toggle you have to assign the opposite of the current state

like SRP2 said above so it would be isPanelShown = !isPanelShown

[steep rose]

i have a public float telling me what my x and z movement is in an absolute value, so yes i can verify its going over limit. It could be my acceleration

[queen adder]

I think that is waht i did wrong let me try

[steep rose]

it actually may be clamping

give me a minute

[lilac finch]

Hello Together!
For the past year, I have been learning C# because I was curious about how real programming is, and I really like it. So, I thought about learning Unity so I could maybe live my dream of becoming a small indie developer. I started watching tutorials and noticed that the guy in the tutorial had a list with the methods he was typing. I didn’t have such a list, so I would love to know if someone knows if this is a setting or a plugin. To understand what I mean, I will send a picture with the list.
Thanks!

[queen adder]

yep that was it now it disapears on click and comes back thank you!

Hello, can you send me a code to open and close the door in my Unity game by pressing the E key?

[rich adder]

its easy as f mate
Just make a public bool on the door then raycast on the door , use E to toggle bool

use the bool to open/close door with update rotation, or just use animation.
also don't crosspost in #archived-code-general stick to #💻┃code-beginner you already posted here

[rich adder]

put debug.log before if statement, make sure its even called

btw if other is player you don't need the player since its already inside other if tag is found

transform.LookAt(other.transform)

Iam trying to check whether the fillings in the cocktailglass are what they should be in the recipe
I printed out the fillings that are currently in the glass with: "Key-Filling: " ...
Then it goes over every ingredient in the recipe and checks if the ingredient is even existing in the glass fillings
if yes it goes over to the else statement and checks if the filling is in a 0.1 range

But in the console output It instantly returns false it prints(no such ingredient in recipe) but it definitely is as printed with key-filling and key-recipe

I hope smb can help me, I would be really grateful

[short hazel]

It's probably due to the fact that ingredients in one dictionary aren't the "same" as ingredients in the other dictionary. See, when you create objects with new, a new space in memory is made to contain it. You might have two ingredients with name "WATER", but they're not at the same place in memory so they're deemed different, that's most likely why it's not found in the dictionaries.
Can you post the definition of the IngredientTags class here?

To make sure my theory actually holds

But how do I fix it then? I have no idea

[desert temple]

I figured out what the problem was, but thank you.

[short hazel]

Make that class implement the IEquatable<IngredientTags> interface. That will force you to implement a custom Equals and GetHashCode method, in which you can provide your own logic to determine whether two IngredientTags are considered the same (maybe by comparing their Ingredient property?). Once you do that, the Dictionary will recognize that you implemented this interface, and should start using it.

[verbal dome]

If you mean the Debug class then theres nothing but DrawLine.
But Gizmos/Handles could help and you can draw Handles in OnDrawGizmos

[stuck palm]

so like for each coordinate in a list i'd draw lines between them?

[verbal dome]

Sure, if you want outlines/a path then use DrawLine

Handles.DrawAAPolyLine/DrawPolyLine lets you draw multiple lines at once

[stuck palm]

i see

i was just trying to draw a 2d shape for a custom fixed point number collider im making

[verbal dome]

Bunch of lines would be easiest then

[merry spade]

OK thank you, but sorry for asking ehm how do i implement sth? like this?:

public class IngredientTags : IEquatable<IngredientTags>

because that throws an error

[stuck palm]

bunch of drawlines then?

[verbal dome]

Sure, or just DrawPolyLine like I said

[short hazel]

Yes that is expected, because you need to actually implement the interface now. Scroll back up and read my full message again

[stuck palm]

awesome, thanks

[merry spade]

Ok thank you I will try it tomorrow because I need sleep now but I thank you very much I will write in here if I get any more errors or if it works tomorrow but thanks for now again

On a subjective note, I find myself substantially less inclined to assist someone who presents themselves as "dick rider." You might find that more people are willing to help if you choose a less vulgar nickname for this space.

It's not clear how the objects in your video relate to the code you posted. It's also not clear what the "grapple state" of the player is within the video. Capturing the video directly on your computer instead of with a phone is also nice - not only is it easier to watch, but we could see additional context such as your hierarchy, and console messages which might have been logged.

[native hill]

sorry I changed my name, I’m figuring out how to record a video right now

[desert temple]

Alright, had to makie an edit, but I'm trying to make it so my script ensures that a projectile is shot out of the given gameObject at the right trigger, which is a player entering. Anything I need to do or add?

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

public class LaunchProjectile : MonoBehaviour
{
    public GameObject projectile;
    public GameObject player;
    public float launchVelocity = 700f;

    private void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.CompareTag("Player"))
        {
            GameObject ball = Instantiate(projectile, transform.position, transform.rotation);
            ball.GetComponent<Rigidbody>().AddRelativeForce(new Vector3(0, launchVelocity, 0));                               
        }
    }
}

[native hill]

I only think it’s related because when I started writing it that’s when everything got glitchy

[raw token]

Is it glitchy even when you're not grappled to something?

[raw token]

That seems fine at a glance - give it a run 👍

[native hill]

yes, I just got a recording I’ll send it

[desert temple]

I did, Which is why I'm very confused as to why it isn't working.

[raw token]

Your collider isn't flagged as "Is Trigger", so OnTriggerEnter() will never be called

[native hill]

sorry that took a while

I can send my components too

[raw token]

That is some nutty shaking... I don't think that this script is responsible however, as it happens without the grapple joint, and the script really doesn't perform any work outside of creating/destroying the joint

[native hill]

oh okay

i think ill try changing the movement script to something more advanced and see if that fixes it

[tame jolt]

how do i make a variable increase slowly

[warm condor]

Hey, can someone explain to me why I am getting this error?

[thorn lake]

public Room GetRoomScriptAt(Vector2Int index)
{
    GameObject roomObject = roomObjects.Find(r => r.GetComponent<Room>().RoomIndex==index);
    if(roomObject !=null)
        return roomObject.GetComponent<Room>();
    return null;
}

I need some help breaking down the Find function here.

I'm looking at the webpage that describes how Find() works but I'm not sure what the "r => r" portion means. A "Lambda expression...?"

Find seems like some search function that returns a match but I'm not sure how to interpret the function's input here

[raw token]

Your class is implementing an interface, but it doesn't implement the members which the interface requires. Your class needs to contain all of the things it's whining about

[warm condor]

ok, and how do I contain all of the things it wants? I barley have anything in my interface. Here look:

public interface ISate {
    void Input(bool KeysPressed, bool IsGrounded);
    void Update();
}```

[eternal needle]

look at the spelling

[desert temple]

I set it on isTrigger, but it didn't make anything happen.

[raw token]

also the using Unity.VisualScripting; - are you intending to use stuff from the visual scripting namespace?

[eternal needle]

look at how this is spelt, compared to what you have in the screenshot above. Also in the screenshot, look at this section here

[warm condor]

oh hahaha. I did not even notice that. But I am still getting errors here even after changing everything. Is it because I has to actually add them in the class or is there something else going on here?

[raw token]

From your screenshot, it looks like your collider is on the tip of that red thing. If that's correct, it seems like maybe it's kind of high - does the player really hit it clear up there?

You might want to throw a Debug.Log("Hit!"); at the top of your OnTriggerEnter() method, just to help narrow down the space in which the problem might be.

[raw token]

That's correct - yeah, you need to add those methods. VS should provide the option to automatically add the basic definitions, or you can write them by hand 👍

[warm condor]

ah ok thank you for your help

[desert temple]

The box is a cube with the mesh collider pulled off. However, I think the problem is that the script is attached to that, so it won't proc without the player touching that cube. So what I need to do is make it bigger, I think?

That was exactly the problem.

[stuck palm]

can you serialise a property?

[slender nymph]

unity cannot serialize properties, but it can serialize the backing field. if you are using an auto property you can target its backing field for an attribute using field: otherwise. a full property has an explicit backing field so you'd just serialize that

note that the auto property cannot be readonly otherwise the generated backing field will be readonly as well which cannot be serialized

[steep rose]

so this is some code to calulate speed on the x axis but can i change that to be local right/left or forward/backward?

    IEnumerator CalcVelocity()
    {
        while (Application.isPlaying)
        {
            // Position at frame start
            Vector3 prevPos = new Vector3(transform.position.x, 0, 0);
            // Wait till it the end of the frame
            yield return new WaitForEndOfFrame();
            // Calculate velocity: Velocity = DeltaPosition / DeltaTime
            Vector3 currVel = (new Vector3(transform.position.x, 0, 0) - prevPos) / Time.deltaTime;
            Newspeed = currVel.magnitude;
        }
    }

[merry shore]

How do I make a variable that contains an object component?

[verbal dome]

Wdym with object component?

Maybe you want the Component type. But that is kind of unusua - what are you actually trying to do?

[steep rose]

public GameObject Obj;?

[merry shore]

Im trying to refer to transform.Position and store it inside a variable.

[verbal dome]

transform.position is a Vector3, which is a value type, so accessing it will create a copy instead of referring to the original

If you want a copy of it then do a Vector3 field

If you want it to stay updated then reference a Transform instead, and access its position when you want

[merry shore]

Ok, thanks.

[bitter sage]

Not sure if this is the place, but I've been getting a ton of trouble with WebGL in Unity 2021.3.8f1. All the way until this recent project webGL was able to export flawlessly. Now it can't. Not sure why.

Tried uninstalling and reinstalling the package. Leaving compression methods to disable, deformation fallback and minimalized stripping Here is the usual errors when I try :

Also can't export an empty project. Not just the project I'm working on.

[ionic zephyr]

How can I check if a SO that heritates from an abstract class has that component (the own, not the abstract)?

[rich adder]

if(mySO is Something theTempVar)

[ionic zephyr]

but I can only access the mother class

[rich adder]

the theTempVar is the inherited SO

[ionic zephyr]

thTempVar?

[ionic zephyr]

sorry, Im just very confused

[rich adder]

if mySO (original abstact) is Something (the childclass SO)

how would i get a local position?

Yes, thanks a lot

it is really intuitive

[zealous widget]

can someone help me install unity

its stuck on validating and Its driving me crazy

[rich adder]

not a code question though

#💻┃unity-talk

[zealous widget]

direct me to the proper channel then please

[steep rose]

new Vector3(transform.localPosition.x, 0, 0) doesnt give me local x position?

[teal viper]

How do you know?

[steep rose]

how do i know? what

[rich adder]

how do you know its not the localPosition's x

[steep rose]

im testing it and its not giving me local position

its giving me global

[rich adder]

then its not a child of something?

[nova swift]

It should be, try debug logging it

[steep rose]

yup

fixing

[nova swift]

Newbie question here:

Should you update a time based boolean that affect physics in update or fixed update?

For example, say you have a timer, and when timer > 0.5f, timerCondition = true. If timerCondition = true, say the physics would change, like the player's speed doubling or a force being applied. Should the timer > 0.5f condition be in Update() or FixedUpdate()? Im inclined to say FixedUpdate as that would seemingly make it deterministic?

[rich adder]

update

do the forces in fixedupdate, unless its Impulse that is fine in Update or 1 frame event

[nova swift]

That somewhat confuses me, because despite never applying forces in Update(), my game still seems to frame dependent on very extreme frame rates, for example 5 fps. And Im led to believe that playing at low frames like this breaks any deterministic physics due to the Update() time variable checks? Unless Unity just isn't deterministic to begin with

[rich adder]

what does deterministic have to do with a bool

[nova swift]

What I mean is like, the physics in my game aren't determistic. Unless that's Unity normally, Im led to believe the reason it's not deterministic is because of frame dependencies, and playing at 5fps compared to 60fps would have the boolean set to true at different intervals in between fixed update?

[rich adder]

I think it has more to do with how floats behave and across different machines, don't quote me on it . Originally from your question if you're only increasing the speed for example, I usually just do it in update, never had issues aross diff fps. the only main issue at low fps is "skipping" almost like teleport

[mint remnant]

I doubt there are any deterministic physics engines out there

[nova swift]

Those are fair points

[rich adder]

pretty sure ECS one has deterministic package

don't quote me on it

[nova swift]

I do have a final question tho, would I be in correct in saying the following:

timer += Time.deltaTime

At 1 fps, it takes the timer 1 second to pass 0.5
At 2 fps, it takes the timer 0.5 seconds to pass 0.5

If I conduct a check if it has passed 0.5, wouldnt the check return true a frame earlier, impacting FixedUpdate?

[mint remnant]

you kinda don't want them to be either, imagine dropping a ball on another and it always falling hte same way

[rich adder]

https://docs.unity3d.com/Packages/com.unity.physics@1.0/manual/design.html
its for specific instance/usecases says here

[nova swift]

Well, I'm mostly interested in deterministic physics as they cater for TAS' or just frame perfect stuff

[rich adder]

multiplayer it certainly would help

[thorn lake]

How does one reference variables from other scripts without making those variables changeable? Do I have to make them public?

[nova swift]

If by changeable you meaning them being in the inspector, you can do it still

[rich adder]

use public get and private set property

[nova swift]

You need them to be public to access them from elsewhere

but if you put [HideInInspector] before the public or private bit it wont show up in the inspector

[thorn lake]

I don't mean changeable in the inspector, I meant changeable in the code itself

[mint remnant]

set readonly

[rich adder]

thats not what they're asking

[nova swift]

My bad then

[thorn lake]

Still useful, was wondering this as well earlier

[rich adder]

making them public and hide in inspector is such cringe when i see it

[eternal needle]

well technically not, there is actually a max delta time in order to combat extreme scenarios like this.
In a scenario with smaller values, yea this could happen but very doubtful itd ever matter

[rich adder]

almost always opt in for props when I need something public

not a fan of pub fields

[thorn lake]

"props?"

[teal viper]

At that fps your game is probably gonna be unplayable anyway. The fixed update would try to update at it's determined rate, which would cause the frame time to snowball to a halt.

[rich adder]

properties

[thorn lake]

hmm, I still need to learn about what those are then

[rich adder]

they are just fancy methods , look into them they're extremely useful

[nova swift]

That's intersting, didn't know it had a cap

[eternal needle]

https://docs.unity3d.com/ScriptReference/Time-maximumDeltaTime.html

[nova swift]

So, with that in mind, I probably shouldn't worry about catering for say, someone playing in 5fps?

[rich adder]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties

[teal viper]

Yes. You should build your game such that it would run at the expected frame rate on the target devices.

[eternal needle]

its best not to worry about cases like these. If your concern is multiplayer, your server wouldnt care if the player was lagging. If this is p2p then yea people can lag switch but 🤷‍♂️ thats not possible to fix really

And if its single player, you simply wont have players if its running at 5fps

[nova swift]

Fair enough, thanks for tips yall

[thorn lake]

thanks sm.

Despite doing a lot of programming in C++ throughout all of my undergrad and then learning a large portion of Python and Perl, C# is hecka unique and confusing to me so far with a lot of its syntax and jargon

[teal viper]

Every language has it's own unique terminology. Think about vectors in c++.

[rich adder]

I found C++ a confusing mess in the beginning so our roles are reversed
you'll pick it up quick if you already learned those

just gotta get used it

[eternal needle]

c# and c++ are written pretty similarly. if anything python is the unique one

[thorn lake]

lol, I can't remember if I even ever learned about them tbh lol

[rich adder]

yeah not a fan of python due to its syntax

fr I get lost without brackets kinda joking but not

[mint remnant]

you have to be sadistic to enjoy memory management lol

[eternal needle]

well in most cases you dont use c/c++ because you want to

[rich adder]

C# the C++ relax mode

[teal viper]

That's very weird. They're like one of the basic things that almost any codebase has.
Basically the C++ lists.
Just my personal opinion, but if you haven't heard about c++ vectors, you probably didn't learn enough of it to extrapolate to other languages.

[thorn lake]

could just be my memory sucking. It was like 8 years ago

[rich adder]

doesnt C++ have getter and setter?

[nova swift]

I agree, though its simpler syntax has helped a few of my friends learn programming, so Im kinda glad for it

[rich adder]

python has properties iirc

[thorn lake]

wait a vector is just a one-dimensional array? That's it?

[eternal needle]

no

[rich adder]

its just 3 floats

in a struct

oh you mean a vector in general in math

[thorn lake]

what no, I mean i programming

I know what it is in math

[teal viper]

It's a type. And it's closer to C# lists, than arrays.
https://cplusplus.com/reference/vector/vector/

[rich adder]

oh c++ vector

[gentle bison]

#💻┃unity-talk pls help

[mint remnant]

c++ doesn't even have lists, it's in the STL added in

[thorn lake]

Dang. Well a list and a one-dimensional array are like....synonomous to me rn so I think I need to do a big refesher

[eternal needle]

dont crosspost, or ping others into your conversation

[thorn lake]

Oh. Maybe that's why I think of lists as one-dimentional arrays

since c++ is my coding foundation

[rich adder]

isnt that basically how vector database work?

[thorn lake]

idk, they're all still synonomous to me atm lol

list, vector, one-dimensional array...

[rich adder]

i think vector storage stores 1 or 2 demenisonal array

for like LLMS n whatnot

[teal viper]

No. C++ vector from std library is basically the same thing as a List in C#.

[rich adder]

ahh ok

[thorn lake]

#💻┃unity-talk im not to keen in discord

so i tried the local position but it didnt work out due to it being the parent, can i convert the position to local position?

    IEnumerator CalcVelocity()
    {
        while (Application.isPlaying)
        {
            // Position at frame start
            Vector3 prevPos = new Vector3(transform.position.x, 0, 0);
            // Wait till it the end of the frame
            yield return new WaitForEndOfFrame();
            // Calculate velocity: Velocity = DeltaPosition / DeltaTime
            Vector3 currVel = (new Vector3(transform.position.x, 0, 0) - prevPos) / Time.deltaTime;
            Newspeed = currVel.magnitude;
        }
    }

[eternal needle]

all of this is so vague, what "didnt work"

[steep rose]

scroll up

[eternal needle]

and what does the local position have to do with any of this

ask your question in a complete message or at least link the context, im not scrolling through a ton of messages to find it

[rich adder]

why do you need local position if its not parented ?

that makes not much sense

if you need the difference get the two world? still same distance no?

[steep rose]

so its basically i need to get the X and Z speeds but if i use global positon and rotate my character to the left instead of reading 8 meters a second, it will read 0.11522 etc

then it will say the Z axis is 8 meters a second

instead of X

[rich adder]

cant you just get the velocity then count a second and compare the two ?

[eternal needle]

still none of what you're saying makes sense, itd probably be a lot easier if you just got the velocity from whatever script is actually moving the object

[rich adder]

velocity is in m/per second anyway no?

[steep rose]

it is in the same script

[eternal needle]

then why do you need to read its position, you have a script which moves the object so the script knows how far its moving the object

[steep rose]

i didnt know the unit of speed for unity so i just said meters, sorry.

[steep rose]

i can use rb.velocity but the same problem persists

[rich adder]

well in unity 3D its always in meters per second
1 unity unit = 1 meter

[steep rose]

alr ty

[rich adder]

they tried matching real life, thats how vel is calculated

[eternal needle]

🤷‍♂️ you still really havent clearly said what the problem even is. "didnt work" and the stuff above is all without actual context. Rotating your character has nothing to do with its position unless you're rotating some parent object with a child object that isnt centered

the rb velocity gives exactly what its velocity is. If you think its wrong, then you're likely doing something wrong elsewhere

[rich adder]

yes rb velocity is doing what ur doing (currentPos - prevPos )

[steep rose]

im not saying the rb.velocity is wrong i just need the velocity in a local space. if i do not use local space it wont give me correct horizontal/vertical velocities.

            Vector3 locVel = transform.InverseTransformDirection(currVel);
            Newspeed = locVel.x;
        }
    }

[wintry quarry]

transform.localPosition is a position in the parent's local space.
InverseTransformDirection converts a direction in world space into the local space of the object itself.

In short, no this doesn't make sense

[steep rose]

the script is on the parent obj so it converts it back to global position, lemmie fix it

[steep rose]

i tried that, its still global

            Vector3 locVel = transform.InverseTransformDirection(rb.velocity);
            Newspeed = locVel.x;

[eternal needle]

You should debug what the vectors are, the velocity and locVel. It most definitely isnt still global

you probably just think it should be something else, but again everything you've written is too vague and you arent describing the actual issue. Nothing more can really be said

[leaden lake]

i'm using np++ to edit. It's good?

[frosty hound]

Nope

Use visual studio, which you can install from Unity Hub

[steep rose]

i have them as a float as a debug to see exactly whats happening, I have explained in detail whats wrong, i stated i need a localposition but i couldnt use it due to the fact im using global possition because the script is using the parents position, so you gave me the Transform.InverseTransformDirection which is giving bad results.

[leaden lake]

There is no place to install VS using Unity Hub!

[frosty hound]

Yes there is

Why would we suggest it otherwise?

[leaden lake]

Where?

[frosty hound]

Click the gear, add modules, install Visual studio.

[eternal needle]

it isnt giving bad results. again, debug the vectors. I really am not gonna entertain this more if you wont go through the absolute basics of troubleshooting. You're claiming the method is giving you a vector back in global space yet you wont print out the vector before and after to see it

[leaden lake]

This?

[frosty hound]

Does that say Visual Studio?

[steep rose]

bro im debugging as we speak, im still getting the same results, unity is telling me the rb.velocity and the LocVel and they are exactly the same from what the float is saying.

[leaden lake]

ah.. ok.. this thing just download the installer, but don't install it

[steep rose]

i know how to debug

[eternal needle]

have them as a float as a debug
Show the actual debug lines then

[steep rose]

can i send a video?

or only pictures

if i can send video i need to reinstall the recorder app i had

[leaden lake]

When I try to install, it return an error, but don't specify that is wrong! Sad.. need to know what I need to do to install VS!

[eternal needle]

🙄 so you arent gonna show the debug lines?
Im just gonna point out that the #854851968446365696 says

Don't
Directly give answers to users who will not troubleshoot.

and im truly not gonna beg you to answer what ive been asking. Someone else can help you

[steep rose]

i never said i wasnt gonna show debug lines, all i asked if i can either send a video or picture to send the debug lines

[frosty hound]

Unity has logs you can see for the install that can give hints, otherwise there's no guessing the issue.

[steep rose]

they constantly update so a picture wont give a lot

[leaden lake]

Weird. . .

[frosty hound]

#💻┃code-beginner message

But you can always look on Google and find people's solutions: https://forum.unity.com/threads/install-failed-validation-failed.1147151/

[leaden lake]

oh yes.. i'm looking for it right now. . rsrs

[eternal needle]

the lines of code is what i meant. the last thing ill say about this is if your global and local direction are the same then that implies your object is at the default rotation.
You can show a video, but still it wont really answer what ive been asking the whole time. What the actual issue is. Because youve said lately is the vector is still global, which is what you assume and not even true to begin with

[leaden lake]

Problem Solved!

[frosty hound]

This isn't visual studio, this is visual studio code which is not what is installed from Unity Hub.

So not sure how you got here, but either way, it counts as one of the programs you can use for Unity. Just make sure you configure it !ide

[eternal falcon]

💡 IDE Configuration

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

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• Other/None

[leaden lake]

I close the Hub and open it with admin. After that the Hub installs the VS.

[bold plover]

I feel that in my soul. It happens. The fact that there are two threw me off at first.

[leaden lake]

Don't know what I did wrong if the Unity Download it.

[teal viper]

What's the issue? The local velocity would be the same as a global velocity if your object is not rotated.

[leaden lake]

I will make it manually!

Maybe it works. .

[steep rose]

i need it to be local and not global. the code i have now should convert it to local but it doesnt

i showed it in the video and a a little above the video

[teal viper]

Did you read my message?

Local and global would be the same if the object is not rotated

[steep rose]

local should be local to where to object is facing, it should not be global. thats why i did inversedirection on it

[leaden lake]

I'm on the right place?

[steep rose]

so the local velocity isnt local, its global velocity

[steep rose]

yeah you seem good now

[teal viper]

Again, if the object is not rotated, then local direction == global direction

[leaden lake]

ah good!

[steep rose]

the point of local direction is to not do that

thats what global is for

[teal viper]

The point of local direction is that it's relative to the object's orientation

If it's orientation matches the world orientation, then global is the same as local

makes sense?

[leaden lake]

Thanks @frosty hound!
You gimme the right means to solve this! +1

[steep rose]

yeah that makes sense, i fixed it, thank you😅

[bold plover]

So if I were making reference to the current player state as the CurrentPlayerState in the main player script, would that suffice for having said state data from said state be sent the main one? That's worded poorly. But basically.

Info from this.

Is sent here.

And I make reference to say the acceleration in current state as the value to use for my player's speed calc in the main script?

Trying to avoid using a bunch of bools and losing track of everything in the process.

[raw token]

You could always access like baseAcceleration in the "main script" from a reference to your state machine like playerStateMachine.CurrentPlayerState.baseAcceleration, sure.

But if you're saying you want to store a reference to the state machine's CurrentPlayerState in like a field and just always try and get the current value from that, that might not, as when CurrentPlayerState changes in the state machine, the field in the "main script" would still be referencing the whatever state the field was initialized with.

[bold plover]

Ok. I'll stick with the former to avoid any issues then.

Thank you. Felt like I was overthinking it and potentially adding a middle man that would cause problems. I'll just reference it with the playerStateMachine.CurrentPlayerState.baseAcceleration.

[devout flower]

Can someone explain a specific case where singletons can mess things up? I’ve looked at articles, but they give very general and hypothetical examples

[raw token]

You could use a property to express that more succinctly though:

private PlayerState state {
  get { return playerStateMachine.CurrentPlayerState }
}

Or have the player script subscribe to events invoked by the state machine when it changes states, and update a reference or values accordingly - but that sounds somewhat messy to me.

I get a little lost in all the possibilities as well 😅

[raw token]

I don't think any pattern by itself can really mess things up on it's own - it's usually a matter of a developer misunderstanding or misapplying a pattern

[devout flower]

Ohhh ok, so it’s the development proccess

[eternal needle]

all the examples will be hypothetical, until you make one and then realize its messed things up. "mess things up" is also kinda vague, like if we're talking about actual logic issues then that could be "i made my player a singleton so enemies could find him. now i want the player to have an ally that can be targetted!" Basically i had one now I want 2.
Other issues people bring up is more with like industry code where you are testing. I found it mostly doesnt really apply in indie game dev

[devout flower]

Oh i see i see

Yeah, the two players example was the only one i saw mentioned

[eternal needle]

One annoying thing also is having singletons that u have to create in every scene, but this part is somewhat tedious to have an alternative. Like if a script creates a bunch of stuff at the start of loading a scene, and you need to call a function for it to run, then you have to find the script somehow. Or take the script out of the scene and associate a scene to this function elsewhere

[devout flower]

Ah i see

I’m fine since i never use more than one scene 😂 (I probably should but i never felt the need to so far)

[queen adder]

it doesnt work i tried making a new project and it says it insalled all pakages but now the error is happening tto all of them wont let me boot it up without going into safe mode

it told me to run unity with tempmemoryleakvalidation so i did but i dont know what to do next

[void thicket]

What version are you on?

[teal viper]

First of all, you can get rid of the test related errors, by removing the tests package.

Unless you're using unit tests in your project

[queen adder]

2023.2.1f1

[void thicket]

Do you need to use 2023? Or LTS is fine?
Your patch version is suspicious too

[queen adder]

should i upgrade to a different version? i was using this one because a friend was using it

[queen adder]

lts is fine

[void thicket]

I recommend LTS, 2022.3.37f1
But it is downgrade so you might encounter some issue when converting

Otherwise at lease use the most recent fix version 2023.2.20f1

[queen adder]

ok ill try this

[void thicket]

Do you use version control? Make some backup before converting

[queen adder]

yes im using version control, how do i back it up?

[void thicket]

If you are using one then just having a commit you can go back is enough

[safe radish]

is there a way i can check if 2 shapes on a 3d grid are touching eachother without iterating over each cell in each direction?

[queen adder]

alr ok

[eternal needle]

depends on what these shapes are and what information you have about them.

you could always use the bounds to see if they overlap but if the shape itself is completely unique then the bounds might not be entirely accurate

[safe radish]

the shapes wont be convex, i want to implement branches and pools in my cellbased fluidsystem, but need a way to check if they are overlapping or touching. i can make custom classes for them, might be easier to give them a hitbox and see if they touch?

[safe radish]

only info i have for them now is the collection of positions they occupy

[rotund forum]

Nevermind I am a fool I used the wrong namespace

😅

Will delete this

[eternal needle]

are you checking between 2 specific shapes, which is what i thought from the initial question, or if anything at all overlaps?

[safe radish]

ideally i want to know if they are touching, but if i cant find a good way to do that i think ill have to resort to checking for overlaps

also could be checking between multiple shapes

[eternal needle]

if you're checking if anything at all overlaps, it might just be better to check through the grid.

[safe radish]

how do you mean check through the grid?

[eternal needle]

Well with a grid, I assumed you're storing which places are occupied. I meant using the collection of positions and seeing if any of those are occupied

Which is pretty similar to your initial question, of iterating over every cell but im not fully sure what you're trying to do with iterating in each direction if you just need to know what's touching

[safe radish]

by touching i meant that they could be occupying neighbouring positions. with overlap that would be both occupying the same position

[queen adder]

its nearly done downloading but now shows this should i just download it manually?

[tiny rain]

Hi guys, I'm not quite sure how I'm meant to hash a Vector2Int into unique values, how are you supposed to combine the x and y axis into a number that isn't recurring accross the map in any way?

x+y would mean that diagonal lines would have the same output...
x+y*... will only modify the way it repeats by squashing it down?
x+y%... will just make it trunciate across y...?

[void thicket]

Why Visual studio?

Unity Hub should have it

[queen adder]

idk

oh

[void thicket]

Oh you checked to install VS

[queen adder]

now it says complete

thats weird

[void thicket]

Do you know the size of the map?

Oh it’s just hashing then it doesn’t need to be unique

Hashes can’t be unique

[eternal needle]

I see, then yea manually checking this is probably the best way to go.

With checking every adjacent cell

[tiny rain]

Wdym, there's no way to not have a lot of repeats across the map? 0.o

[eternal needle]

you should explain what you're actually using this for. this x+y x+y* etc stuff is an XY problem

[eternal needle]

of course theres no way. how do you fit 2 numbers into one, where the original 2 can be any number. You cant

[tiny rain]

So on the map, some floors have decorators, however I don't want to save all that extra data to make it show the same decorator each time you load that position

[eternal needle]

i dont really know what a decorator is in this case, but could you not just store this by some ID? What would hashing a Vector2Int even do for you here?

[tiny rain]

Uhm... Maybe I can fit one on top of the other? Like x + y/mapSize?

[void thicket]

Yeah that sounds like downgrading issue, you probably want to modify some package.json :/

[void thicket]

If you know the map size x + (y * width) is how you convert 2D to 1D

[tiny rain]

Storing 1000000 integers is kinda absurd '^^

I intend to generate a rng instead as in that case I don't need to save anything

[eternal needle]

whats 1 + 0, and whats 0 + 1
If you had a defined max size, then it could be possible but i think theres a better solution out there. Like specifically what are you hashing a Vector2Int for

[tiny rain]

Seriously I think that not even terraria saves the rng for each tile

[void thicket]

"hash" is meant to be non-unique

[teal viper]

Why? That's just around 4 MB. If you really need to store that, then why not?

[tiny rain]

It's such a waste...

[eternal needle]

4mb is a waste? dear lord

[teal viper]

Depends on what you need it for

[void thicket]

I think you are using term "hash" wrong

[queen adder]

should i try to find the package or just go to 2023.2.20f1? i dont know what package im looking for

[tiny rain]

I think that tbh, if you hash that probably the result should be good enough

[eternal needle]

i dont think you know what hashing is

[void thicket]

Hash is not compression

[tiny rain]

Hashing is to turn a number into a psuedo random number, ain't it?

With same output from the same input each time?

So what I want is a random number for each tile, but to be able to get that same number whenever I load the tile

[void thicket]

In Packages/manifest.json I think you should just delete the line contains the said accessibility package

[eternal needle]

and also, this seemingly came out of nowhere. Either way you're gonna need to save the same amount of data. Again, what is this Vector2Int and why are you hashing it? What is a decorator, can you not just give it a specific ID and save that ID?

[teal viper]

You're confusing it with random seeds

[void thicket]

No

[tiny rain]

So, imagine a map in the form of a grid, the map can be of any size, but at minimum I expect 100 by 100, although 1000 by 1000 is my target standard. Each tile of the map has a floor type, it could be dirt, mud, or like, grass.
Grass tiles have decorators, they might spawn a random grass object on top when loaded
What I want is to get the same random grass on top whenever I load that tile

[void thicket]

Hashing is making your variable, of any size, to fit in certain size
It does not guarantee uniqueness, you cannot recover original value from it

[teal viper]

You could save the seed that you use for the Random function for deciding whether to put an object on top of it or not.

But you can't get that seed after the generation

Or have manual control over it

[tiny rain]

Yes but, the seed of the generator isn't the only thing deciding, it's also the position of the tile...

I seriously thought that it's called hash functions tho?

[eternal needle]

i see nothing stopping you from using ID's for the grass object, or what dlich said about storing the seed then just generating everything in the same way

[teal viper]

Well, if the generation algorithm is determenistic, then the seed should be enough. You probably have access to the tile position anyways.

[tiny rain]

Eh... Fine, Imma jsut ask it directly, how to generate a psuedo random number from a seed, a x position, and a y position

[teal viper]

A hash is a way to compress data in such a way that there are values that would overlap for sure. They're just usually outside of the range that you're interested in.

[tiny rain]

All three values are meant to generate a rng that doesn't show some visibly repetitive/incrementing patterns

[eternal needle]

theres no way you need a random number here if you're trying to store information about what was generated

[teal viper]

Ultimately you need to compress these 3 values into 1 seed. How you do it is up to you.

[tiny rain]

Storing a random number for each chunk seems bad... I want to avoid storing extra variables in each chunk as much as possible

[teal viper]

For example, you could use the first 2 bytes of the int for the random number and the 3d and 4th for the x and y positions

[eternal needle]

you havent even accurately said why you cant just store a single ID. You were also told that hashes cannot give you the original number back. How do you expect to use this data if you're storing a number generated with a one way function? What do you think you're actually gonna do with this number

[teal viper]

Thought, that would limit the range of tile positions that you could use

[teal viper]

Well, you either store the data or pay with precision and control. Take minecraft for example. It saves a lot of the state of the world and thus the save size is huge

[tiny rain]

I can, but like I said, it just increases the memory cost of each dimension quite a lot

[eternal needle]

if you're building to anything better than a samsung toaster, really just cut the crap and make what works simply. All of this is "i think its bad" with 0 experience in it

[eternal needle]

And like i said, your solution right now doesnt even seem like a solution. You're trying to store a hash of a number, for what purpose? How do you expect to get the original values back to read the thing

Whats the point of even storing this

[tiny rain]

I'm not trying to store it 🤦‍♂️

[teal viper]

Ultimately, the amount of data you can encode in a unit of memory is limited. So if you want to save more data, you need to use more memory. Deterministic procedural generation is one way to compress that data, but it's not without flaws.

[tiny rain]

Told you that I want the same number for the same seed, x and y, without needing to store it and without them showing an obvious relation to eachother

[tiny rain]

I don't really get the issue with hashes... Okay, uh... There're basically formulas that shuffles a number non-sensically

Usually utilizing bit shifts, modulos and multiplications

[eternal needle]

everytime ive asked you something of it, storing numbers was brought up so I thought this was in relation to storing.
You could just use a single instance of random then and generate it from 1 seed at the start. I still dont see what you need this other seed (of seed, x, and y) for

[tiny rain]

I kept saying I want to avoid storing numbers tho...

[tiny rain]

Because you load the chunks in runtime

[teal viper]

The issue is that hashes are not unique. And also that you would probably need to implement your own hashing algorithm for your specific need.

[tiny rain]

And reload them in runtime too, just like in minecraft

[eternal needle]

1000 x 1000 can easily all just be generated at once

[tiny rain]

Count all the dimensions in, and each world

You'd be adding at least 16mb per world, even if this is a small addition, it'd add up significantly when saving things unnecessariliy too often

[teal viper]

Well, then you'd need to use a random seed and a determenistic generation algorithm. That's how minecraft and other similar games do it.

[eternal needle]

🤷‍♂️ what other unknown aspects am i supposed to account for? Im going purely off information you've said

[sour fulcrum]

I have an int and I'm trying to lerp it into a usable index in a list I have but something here seems to be rounding weird,

float lerpResult = Mathf.Lerp(0f, (float)(gizmosColors.Count - 1), (float)intValue);

The List is 6 in length and i'm giving it 1-8 and this always results in 6, What am I goofing up here

[teal viper]

It still saves a lot of data normally as well

[sour fulcrum]

I know I gotta turn it back into a clean int after this but this is where my issue is

[tiny rain]

Yes, but I kept asking how to take a position into it lol

[teal viper]

And I answered it

[tiny rain]

I assumed that hash128 is the kinda thing used for it

But it takes 1 input

[raw token]

Probably intValue

[teal viper]

@tiny rain Here: #💻┃code-beginner message

[sour fulcrum]

is there a better way to tell that stupid number to be a float

[eternal needle]

this doesnt make sense, the 3rd param of lerp takes in a value of 0 to 1. Giving it (what was initially an int) will either be its lowest value, or highest value

[tiny rain]

Ah, right... Um... I guess, that's why I said that maybe I could just compress them together before hashing by x + y / worldSize, or x+y*worldSize if I'm making it an integer

[sour fulcrum]

ah fuck right

thank you

i forgot third param was 0-1

[teal viper]

In which case you wouldn't need a hash anyways. You can use the resulting value as is. I don't understand that obsession with hashes? Considering you don't seem to understand them.

[tiny rain]

Why hashes? Cus if you, say, use it for whether grass spawns, the value would still show a very recognisable pattern, no?

Cus y++ might give a very linear change to the value, thus making the grass pattern visibly repetitive

[teal viper]

It depends on the algorithm you use to generate the grass.

And that being said, I'm not sure that hashes would help you with that anyways

Like, what exactly do you want to use them for?

[tiny rain]

To break an obviosuly repetitive pattern? https://stackoverflow.com/questions/44593626/how-to-create-a-hash-function-for-use-in-noise-generation

[teal viper]

Hashes are not random numbers. They're very much deterministic and preserve patterns. In addition they are not unique and could correspond to several of the same values.

[tiny rain]

Well, I do need it to be deterministic as I don't want to save the output in the map, so that's what I actually need, I just need it to not have an obvious pattern to the player

Like in minecraft where the same seed always gives the same map, that's what I'm seeking

[teal viper]

This is diving into Perlin(or any other) noise algorithm itself. I'd avoid messing with that. And it's probably not really what you need anyways.

[teal viper]

Then use Random numbers.

[tiny rain]

Perlinnoise is only built on top of random numbers like this

[tiny rain]

You can't retrieve the same Rng with UnityEngine.Random with the same seed... Still don't get the problem here?

[teal viper]

And you've been answered many times regarding that. Nowhere here hashes are relevant

unless you're trying to write your own noise library

[teal viper]

But you can with dotnet Random

[raw token]

It sounds like you might using "hash" interchangeably with like "procgen algorithm" or maybe just "pure function"

[teal viper]

https://learn.microsoft.com/en-us/dotnet/api/system.random?view=net-8.0

[tiny rain]

Idk what pure function means

[raw token]

Same output for same input without side-effects

[tiny rain]

Pretty much, except that when you, for example calculate it for each pixel on a texture, the texture wouldn't look repetitive

[teal viper]

Also, you can do it with unity random as well
https://docs.unity3d.com/ScriptReference/Random.InitState.html

[tiny rain]

PerlinNoise is an extension on it, a hash function isn't a perlin noise itself, as it's specially programmed to make the wave effects

[teal viper]

I'd still use the dotnet one, as you don't need to reset the state every time.

[tiny rain]

I'm pretty sure that setting the seed for each position in that UnityEngine.Random's case would do something like what happened in this video... Can't tell for sure
https://www.youtube.com/watch?v=ZZY9YE7rZJw&t=1688s

At 10:35

They set the seed but the result is visibly not random, as it relies on jumping states to make it seem random

[teal viper]

Why would you set it for each position?
But yeah, you'll need to maintain the random state between different seeds and steps of generation, which is why I suggest using the dotnet one.

[tiny rain]

Told ya... I don't intend to save it, so basically I should be able to get the same random number at a certain position without dependency on extra values like it being the 100th rng generated from the seed

[teal viper]

You seem to be confusing many pieces of information technology. Keep it simpler. Start simpler. Learn how random seed work and how you can have multiple random generators with different seeds.

[teal viper]

Wat? Again, I feel like you're confused. At this point I really don't understand what you have in mind.

You do realise that you would need to save at least something, right??

at least the initial seed

[tiny rain]

These kinda functions

[teal viper]

Otherwise you would never get the same map ever again(in realistic time range)

[tiny rain]

They are deterministic, yet they don't rely on hopping states x times starting from x seed to seem random

And they look random

[teal viper]

Well, that's exactly what a random function does

It just has a different algorithm under the hood

in your case nLehmer is the seed

• the hexadecimal at the function start

[tiny rain]

Yeah... But some numbers if you set a number with a visible pattern as a seed, the output keeps the visible pattern

[teal viper]

Your algorithm would also have a visible pattern depending on what values you feed it

[tiny rain]

The Lehmer function instead doesn't have such an obvious repetition despite feeding it a visible pattern

[tiny rain]

Yes, if you feed it stuff like x+y

[teal viper]

Random wouldn't have a visible pattern either. It's white noise

[tiny rain]

Which makes it obviously repeat in diagonal strokes

[tiny rain]

Please watch that video at 10:35, they were setting the seed for Rand(), and it didn't look like a white noise at all

That's the problem I was talking about

Rand relies on the previous state to generate a decent looking rng

Which, if you set the seed for each position, destroys the purpose of it

[teal viper]

Again, you're confusing concepts. They get a repetitive pattern because of how they use the random. You would get a repetitive pattern with your function as well if you feed certain values into it.

Anyways, it seems like you already have all the answers yourself, so I don't see any point in continuing this conversation.

[tiny rain]

No... It's really proven in the video that some look random, some look repetitive, despite all being fed as seed (y << 16 | x)

Rand() when fed that as seed gives diagonal strokes, while Lehmer gives a white noise

[teal viper]

Great. Then I guess you've got your answer.

I'd also point that srand/rand is C++, and there's absolutely no guarantee it has the same implementation as the C# Random

[tiny rain]

Yeah, that's why I mentioned that it might cause issues

Not that it certainly will

[teal viper]

I can't believe I spent that much time on that meaningless conversation with arguments relying on a different function from a different language in a very specific scenario...

[half egret]

C'est la vie

[spare mountain]

así es la vida

[raw token]

viva la fromage

[eager spindle]

theres an off chance that the rand() is implemented differently between platforms too

[half egret]

Almost definitely is

[spare mountain]

CHEESE

[eager spindle]

if its that important you might as well make a backend server that handles all this for you

[eternal needle]

precisely why i stepped out early. when it was clear the exact issue wasnt gonna be brought up, instead bringing up more details only when it counteracted a solution presented

[half egret]

The source of entropy on Unix is different than the source of entropy on Windows, and that's not even considering the hardware

[pliant sleet]

So I have certain prefabs that I spawn every several seconds and I want them to be destroyed when they're out of bounds. The problem is that when I try using a separate gameobject to destroy everything it touches it simply doesn't work. I have also tried destroying that prefab after 5 seconds but it still doesn't work. Any suggestions ?

[eager spindle]

are you using OnTriggerEnter by coincidence?

[pliant sleet]

yes, 2D

[eternal needle]

you need to specify more about what "didnt work". this is very vague, look at the #854851968446365696 on what to include when asking so people dont need to play 20 questions

[pliant sleet]

because i am making a 2d game

[eager spindle]

could you add a Rigidbody2D, with Kinematic on?

to the trigger

one of the objects on this needs rigidbody

[pliant sleet]

well it doesn't provide an error, nor it destroys that object

[tiny rain]

Idk why you kept misunderstanding my question tbh

In my point of view y'all seemed confused, I think that it was a communication issue instead

[eternal needle]

i didnt say anything about an error, but to look at the #854851968446365696. you need to include code

[pliant sleet]

sure

[half egret]

If several people are misunderstanding your question, maybe the other people aren't the problem as a note.

[eager spindle]

an object with a collider but no rigidbody is not expected to move. thus the physics engine will not take that into account

[tiny rain]

Ye, that's why I suggest communication issue, not sure what I was saying that was so confusing in the first place

[eternal needle]

the message you replied to literally states why. You kept bringing up something new when a solution presented didnt match your hidden use case.

[pliant sleet]

that is all the code for the gameobject that is supposed to destroy the prefabs

i have also set the isTrigger

on

[tiny rain]

To me, I was talking about the same thing pretty much all the time 😂

[pliant sleet]

that worked bruh

[tiny rain]

Only going off track to explain what I needed it for

[pliant sleet]

thank you so much

but why does the trigger need a rigidbody ?

[eager spindle]

@pliant sleet

look into how physics engines work too

making one is fun

[pliant sleet]

I will

because I barely understood that

[eager spindle]

unity uses nvidia physx, a physics engine that uses your GPU

[eternal needle]

you also might wanna consider having the rb's on the moving objects rather than the destruction area

unless you want it to destroy truly everything that comes into contact, and not just those select objects

[pliant sleet]

nah, truly everything, because only the prefabs that are moving can touch that trigger

Thank you for the advice

on 3D games it doesn't work like that

[eager spindle]

oh it works the same way in 3d actually

one object needs a rigidbody for the trigger to work

[pliant sleet]

then it's just on me because I didn't take that into account

[topaz mortar]

For some reason every time my code throws an error, it sets the Scale of the items the next time I start the game to 0
When I set the scale back to 1 in play mode and exit without error, the items load properly the next time
But every time I have an error, it will set all items that were in the hierarchy the previous play to 0 scale the next time it runs
Even though all items are Instantiated in code from a prefab, the prefab scale is set to 1 and my code does not touch scale

So none of these items are in my Hierarchy while in edit mode, they are created while in play mode

Some values driven by VerticalLayoutGroup

[tiny rain]

Whelp, guys, after testing, yep, there're you go, exactly what I meant

1. UnityEngine.Random will show a very consistent pattern when seeded with (x << 16 | y)
2. System.Random is repetitive too, except in another pattern

However, to prove the other part of what I was saying, this is what Lehmer does, with the exact same input:

I'm just telling this only as a final statement to prove my points correct honestly, else I wouldn't've even bothered

I was only hoping to find a built-in, which I suspected to be hash128, else I'd be using Lehmer

[topaz mortar]

would you also know how to fix this? can't really figure it out

[eager spindle]

ok ill spoonfeed a little but your parent object has a verticallayoutgroup

you'll need to play around with the values a bit

also see the Layout Element component which gives you control over what happens in a layout group

[topaz mortar]

not sure what I should change to make it stop setting my child scale to 0?

[eager spindle]

remove control child size

and put a layout element component on your child

[teal viper]

This only proves the point in the constraints of your specific scenario. And you're probably not even using the function correctly.

[tiny rain]

It totally works how it does, you could look at the tutorial and you'd get what I mean with it

They're using it the exact same way

And this is exactly what I was asking for- Converting a position into a psuedo random number, without them showing an obvious pattern

Both Dotnet and Unity's random doesn't cut it, likely made to be faster but with this weakness

[teal viper]

I'm not saying that it doesn't work. I'm saying that dotnet or unity random would work as good if used correctly

[tiny rain]

They rely on the previous "state" or "seed", they cache the previous value to generate the next one

If you used that to try get the rng it'd give at a position, you'd either need to generate till the xth rng from the same starting seed

Or set the seed to a number made with the position, but that fails to look random

[teal viper]

Yes. That's how it's done usually. A deterministic algorithm always generates in the same order, which is why the seed based random generator works.

[tiny rain]

However, perlin noise is different, if you gave it the same x and y input, the output will always be the same, no matter what you do

However, the wavy look comes at a cost, which isn't worth it for this purpose

That's why, there need to be another algorithm to generate a rng from an x and y value, one that doesn't perform such redundant operations

That's where Lehmer comes in, I knew that I could use it, but I wanted to see if I could get away not writing custom noise functions

Sorry that it's a waste of time after all, I guess, thanks for trying 😂

[eternal needle]

It isn't a weakness of c# or unity if you're using it wrong.

Anyways isnt noise just a hash function?

[tiny rain]

It's the weakness of the function, it was meant to be random, but it wasn't made for this.
I was suggested to use Unity or Dotnet's random by you guys, while I knew that it's extremely unlikely to work for this case

[slender nymph]

you should show your actual implementation to ensure there were no flaws in it

[tiny rain]

That's why I was talking about hash functions all this time 🤦‍♂️

Also, no, not all noises are just a simple hash function

Perlin noise have some sort of lerping between points, those hills

Voronoi noises, despite being able to use hash to determine the position of the points, still need extra checks to know the value in between

[eternal needle]

Bad code is bad code. You can 1000000% have it work for your use case, but simply didnt write it in a way to do so

[eternal needle]

I dont know what you are face palming for, you're the one who asked how to generate prngs multiple times above

[tiny rain]

Partly cus you were the one saying that I wanted to store stuff, and said that I kept saying storing, while being the one who suggested storing in the first place, and repeated on it many times over

While I said that I wanted the same rng for the same x y, without storing the value

Please, I don't know why y'all keep thinking that there was another way or whatever stuff I was saying, can't we just stop talking gibberish over stuff that's already done?

[eternal needle]

Storing it or not is irrelevant, you literally just said you wanted to generate a random number.
Anyways doesnt matter as long as you found something that fits your desires

[eternal needle]

If you didnt want a discussion on it, then maybe dont post above about how c# and unity random has this "weakness"...

This kind of talk genuinely has beginners think it has flaws and they try to go find other methods when it's perfectly fine to use

[tiny rain]

Well, maybe weakness was "wrong", great, it was just simply not the tool for generating an rng from an x and y value at all

And I didn't start about those two tools in the first place, okay?

[tiny rain]

Sure, here you go

int seed = position.x << 16 | position.y;

UnityEngine.Random.InitState(seed);
int unity = UnityEngine.Random.Range(0, 5);

System.Random sysRand = new System.Random(seed);
int system = sysRand.Next(5);

int lehmer = (int)Lehmer((UInt32)seed);

[slender nymph]

so for every position you initialize the random instances with a new seed? that is literally the definition of using them wrong

[tiny rain]

I was asking for something that generates something with an x and y value

And I didn't even think of using them before, it was on dlich's suggestion

[slender nymph]

that doesn't mean you should be re-seeding for every position

[tiny rain]

To me it was already unlikely a good idea

[tiny rain]

They rely on a previous state to seem random, seriously, I said that so many times by now, you can't get a reasonably random looking something with them if you want it to use x and y

[slender nymph]

you can't reasonably expect actually random numbers if you just feed it similar numbers as the seed every single time you get a new number

[tiny rain]

Try writing me a function that takes in x and y, and gives the same output consistently for the same x and y values, while looking random

[tiny rain]

Lehmer is one of those that does look random, there're plenty of hash functions that does it

[teal viper]

Just one question. With your current implementation, there's no way you can generate different worlds with separate seeds. You do realize that?

[slender nymph]

"guys, i'm going to misuse these random number generators then complain when they don't look as random because i am consistently misusing them"

[tiny rain]

Yep, but I'm pretty sure I know how to stack a seed into it, too

[tiny rain]

Jokes on you, it was more like:
"Guys can I have the screwdriver please?"
"Why don't you try it with a wrench?"
*Proves with tests that a wrench don't work
"Insert your joke here"

[teal viper]

I can imagine it causing visible patterns on different scales, but you do you.

[tiny rain]

Probable... However it's said to be pretty good for it's speed

So I imagine it to be quite reliable

There're better hash functions... But they are usually slower

[eternal needle]

can you stop with the ego? your first question wasnt "can I have the screwdriver" it was something that was literally impossible #💻┃code-beginner message and then people played 100 questions to even guess what you want.

[tiny rain]

This is truely war without reason, it wasn't ego, it was a counter attack to someone else tryna roast me

[eternal needle]

can't we just stop talking gibberish over stuff that's already done
you can also stop responding, but we all know this was written as a "im the bigger person" message

[tiny rain]

C'mon, y'all say the exact same type of stuff
