[naive plank]

Yeah, I ment explicitly for singletons

[rich adder]

yup

are you like doing all this last minute 🤔

[inland gazelle]

Made the script a component of an object, then passed in the object and grabbed the component

[rich adder]

so in the inspector ?

[inland gazelle]

Yes. Grandmother got injured, very minor but at her age everything is major

[inland gazelle]

Yes

She's fine now dw

[rich adder]

ohh alr.. teacher didn't want to give you extension time ?

[naive plank]

Let's see if it works now:)

[rough granite]

feel like there is a group of uni students doing everything last minute currently we just had another person that was talking about it being their uni assignment

[inland gazelle]

nnope. cause the semester ends toda

[naive plank]

+1 Last minute is the way

[inland gazelle]

IM SORRYYYY lfmao

[naive plank]

All my courses so far are 2 months, I do everything the last 2 weeks lol

[frigid sequoia]

Can I not like, do this on the editor? Do I have to make a script for that?

[naive plank]

you can

Let me check my script quickly

[rough granite]

had a coworker complain to me cause i called my classes scripts 😅

[naive plank]

think I removed it, give me one more sec

[frigid sequoia]

Like, the whole point is, I wanna keep it simple, not use a script, that's why I am using the legacy animation on these and not an animator lol

[naive plank]

ow wait

Im not sure then, im sorry

its almost giving nigel thornberry 😄

OK LAST QUESTION FOR ME YALL

so i have it such that the pause menu is an additive scene

is that the best idea? who knows but not important

I have the system like this, where theres a variable set to 0 at the top

that way you cant spam pause and create a million pause menus

but now, when I unpause and puase normally, the pause menu does not show up again

[rough granite]

you load a scene for when pausing? odd

[inland gazelle]

correct

but rn it gets the job done

is there anything that would cuase this behavior?

this is the pause trigger

its also where i stop time

[rough granite]

cause what behaviour?

[inland gazelle]

I pause and resume, everytihng is fine

but when i puase a second time, the pause menu never shows up

though time does freeze

[rough granite]

not sure i don't use scenes for my pause menu also isnt common to do it this way

[frigid sequoia]

Are u like.... loading the pause menu as an additive scene???

[inland gazelle]

yes

[frigid sequoia]

Why???

[inland gazelle]

cause i dont have time for a better solution rn

[frigid sequoia]

That's like way more complex than it needs to

[frigid sequoia]

That's probably the worse solution you could have

[rough granite]

wouldn't doubt if they have a few minutes left for this project :/

[frigid sequoia]

Just pack the scene that is the menu into a gameObject, place it on the main scene and toggle the object on and off when pausing and resuming

[inland gazelle]

yup, thanks for the advice!

got it in after a bandaid fix

dang grandma tripping like 3 days ago 😭

[crimson sluice]

I wrote the code gay instead of say

[livid mirage]

hello everyone, is this where i ask for help?

[sharp solar]

yes

[livid mirage]

ok i'm new to unity. i have an issue with player movement, i have two scripts controlling 1) Basic Movement left and right 2) Jumping. How do i get the movements to be able to be pressed together? example press "D" and "Space" together

[sharp solar]

show code snippet

sorry

[naive pawn]

do they not already work like that?

[naive pawn]

(why not a bool for this though btw. still not good, but still better than an int)

[glossy carbon]

Hello everyone, how are you all

your movement script is resetting y velocity to 0
your jump script is resetting x velocity to 0
change both to only modify the dimension they actually care about

Can i ask a question in here ? its about the camera following the sprite

[sharp solar]

screenshots are fine

[sharp solar]

yes

just add current vertical velocity to your move script and current horizontal velocity to your jump script

[naive pawn]

[glossy carbon]

I'm stuck with getting my camera to follow the sprite without turning, I moved the camera out so its not a child of the sprite and added a script i found on google but when i add the sprite to the script the camera background covers everything in the scene with the background colour

[naive pawn]

is the camera perhaps getting flung off the map

[naive pawn]

god this is even worse, see the code command above

[glossy carbon]

Sorry im very new and dont know what the code command is

[naive pawn]

this

[sharp solar]

programmers trying to read code without brainrot syntax highlighting

[glossy carbon]

O i thought screen shots were ok

[north kiln]

Also, just use cinemachine, it's worth learning as in most cases you'll end up making your camera logic more complicated in the future anyway

[naive pawn]

i don't need the syntax highlighting, i don't even get it on mobile
i want it as text

[naive pawn]

thank you

couldn't this logic in particular just be having the camera as a child of the player? or are you planning to add more logic in the future?

[glossy carbon]

truthfully im not sure

[naive pawn]

what about the second question

[glossy carbon]

im trying to jsut get my sprite to turn without the camera turning as a input movement

[naive pawn]

what do you mean by turn?

[sharp solar]

what have you set offset as

[naive pawn]

is that supposed to be a gif, or...?

[glossy carbon]

so at the moment the camera changes direction but the spaceship always points upwards

screen shot of the game

[naive pawn]

ok, so you didn't actually answer my question

[glossy carbon]

so you cna see the stars moving underneath the sprite but the sprite never turns

[sharp solar]

youre sure camera isnt a child of the sprite?

[naive pawn]

so your player is rotating on z?

[glossy carbon]

I did the new movement in unity (atleast the tutorial said it was new )

[naive pawn]

you are not answering my question

[sharp solar]

just to be sure you havent got the movement script attached to the background right?

[naive pawn]

how are you turning the player

this is unrelated to input

and this is on the player, correct?

[glossy carbon]

yes sir

[sharp solar]

check

[glossy carbon]

Im sorry for not knowing all the answers

I started yesterday

Im a massive NOOB

[sharp solar]

that is why youre here

[north kiln]

The offset is set to 0, so your camera will be directly on top of the player?

[sharp solar]

wouldnt be a very good code beginner channel if you werent welcome

[sharp solar]

should fine for orthographic projection

[naive pawn]

oh yeah you do need a z offset, usually -10

cameras render what's in front

[glossy carbon]

I can change the offset but i was doing a topdown not a isometrical view , does that matter?

[naive pawn]

no

this is just how far the camera is from the plane of the world

[sharp solar]

set it to 0, 0, -10 see what happens

[naive pawn]

you're working in 2d, so you'll be using X and Y and ignoring Z
what x/y represent is dependant on the perspective, but it'll still be x/y

[glossy carbon]

You legends

that worked first time Woop Woop

Thank you

really apprciate that

[sharp solar]

does anyone know why that worked 😭

z issue fixes rotation issue

[naive pawn]

z issue fixes rendering issue, not rotation

[north kiln]

[when adding] the script the camera background covers everything in the scene with the background colour

Rotation was never the issue

[sharp solar]

mb

i was thinking of this

[glossy carbon]

I took a moment to think about this and i understand now the problem

I needed to back teh camera up above my scene so it could see it

Thats right ?

[sharp solar]

yes

[sharp solar]

as vertx and Chris said camera only sees whats infront of it

[glossy carbon]

awesome i understand NICE

Thanks again

on to making a mini map now

[thick saddle]

Hey in my top-down game I'm trying to make it so when I hit this enemy it goes in the direction the player is facing (the player is facing the mouse btw). The first method is for when it bounces off of walls which works and the second one is when it gets hit which doesn't work, it usally makes the enemy's velocity slow waaay down. Any help is appreciated

how/where is lastVelocity set, also !code

private Vector2 lastVelocity

in the class

[frail hawk]

this is the declaration, where do you set it?

[thick saddle]

private void LateUpdate()
{
    transform.rotation = Quaternion.identity;
    rb1 = GetComponent<Rigidbody2D>();
    if ( rb1 != null )
    {
        lastVelocity = rb1.linearVelocity;
    }
}

[naive pawn]

🤨 where is TakeDamage called from? specifically via what message

also you should cache or serialize the rigidbody instead of getting it every update

[thick saddle]

public class Weapon : MonoBehaviour
{
    public float damage = 1;

    private void OnTriggerEnter2D(Collider2D collision)
    {
        NormalEnemy enemy = collision.GetComponent<NormalEnemy>();
        if (enemy != null )
        {
            enemy.TakeDamage(damage);
            
        }
    }
}

[naive pawn]

(and there you should use TryGetComponent, but we can worry about that later)

wouldn't you want to set lastVelocity in FixedUpdate so it syncs with the loop cycle where the trigger happens

[frail hawk]

can you Debug.Log the mousePosition please? how does it look like, you are using a Vector2

[thick saddle]

I think it is the x,y coordinates of where the mouse is positioned in the world

bc the camera follows the player and it was a different value after moving

[frail hawk]

yeah ScreentoWorldPoint is a Vector3 in world space

[thick saddle]

ah so I can't use that with Vector2?

[frail hawk]

you can but you need to also define the z axis , maybe manually

[thick saddle]

apparently input.mousePosition is already a Vector3

[sour fulcrum]

it is but only with 2 values

[frail hawk]

yeah this

[thick saddle]

I want that though right?

am I misunderstanding this then?

[sour fulcrum]

its stored as a vector3 but only the x and y have anything afaik

[frail hawk]

yeah z is unassigned

[thick saddle]

is that a problem? I'm not rly messing with the z axis

do I need to set it to 0 or something to fix it?

[frail hawk]

scroll up and see what i said

#💻┃code-beginner message

  Vector3 mousePos = Input.mousePosition;
  mousePos.z = Camera.main.nearClipPlane // or some hardcoded value as you wish;
  Vector3 worldPosition = Camera.main.ScreenToWorldPoint(mousePos);
  Debug.Log(worldPosition);```

this will give you proper values, first you assign the mousePos than you feed that into the ScreenToWorldPoint

[thick saddle]

thank you 🫡

[raw tulip]

I imported the first person and third person starter assets, how can I make it such that I keep the armature but have an fps cam and third person cam?

I have a script that switches between the cameras, but everytime I try making an fps camera a child of the armature head bone, the movement and looking around gets very wonky

Or is there a way I can duplicate the third person camera put it in front of the head and have it look and move like a fps?

[frail hawk]

create an empty gameobject at very top of the player hierarchy and attach the cam to this gameobject

[raw tulip]

Attach the thirdperson cam to it?

[frail hawk]

yes

[raw tulip]

So duplicate it yeah?

[frail hawk]

you can duplicate camera there is no problem, at runtime you can just disbale and enable them

[raw tulip]

Which ones would I duplicate?

[frail hawk]

i have no clue which one you want to duplicate, it is your game

[raw tulip]

This is from the Third Person starter assets

[frail hawk]

looks like you are using cinemachine

[raw tulip]

Yes

[frail hawk]

i´d suggest you ask your question there instead #🎥┃cinemachine

Hi! I'm coding an UI bar for entities that looks at the camera. Currently I did everything but I can't get it perfectly horizontal in respect to the camera

That's a screen. Full health bar, correctly facing the camera, but not horizontal

void Update()
    {
        if (showCooldown > 0)
        {
            healthBar.SetAmount((entity.health / entity.maxHealth) * 100);
            healthBarObject.transform.position = healthBarPosition.position;
            healthBarObject.transform.LookAt(
                healthBarObject.transform.position +
                (healthBarObject.transform.position - playerCamera.transform.position)
            );

                healthBarObject.SetActive(false);
            }
        }
    }

That's the code I'm using to rotate it towards the camera.

(only the LookAt row actually).. How can I fix that?

[gaunt raptor]

Quick question how you make a boss fight in 2d side scroll game like blasphemous or somthing like in cuphead

[cosmic dagger]

Is the health bar in 3d or 2d? LookAt uses all three axes to look at the camera. Usually, you'd use UI for the health bar as it will always face the camera correctly, and track the object position to update the health bar . . .

[frosty hound]

The same way you'd make a normal bad guy that isn't a boss. Decide what you want it to do, and then implement the behavior.

[unborn veldt]

3d

the health bar is an object spawned in the world. I used this approach because using an UI element would require instantiating the health bar in the main player canvas, which is not easy to reference

[sour fulcrum]

Anything is easy to reference, you might just be missing some knowledge in your toolkit 😄

[naive pawn]

why not use world space canvases

[cosmic dagger]

Why do you have to instantiate it in the player canvas? You can choose which canvas it belongs to . . .

[naive pawn]

so you get ui in the world

[unborn veldt]

I'm using it in the prefab

[sour fulcrum]

Ideally they might actually want 2d for this, no?

[naive pawn]

hold on i think im missing context

[cosmic dagger]

I spawn all my enemy health bars in their own canvas so I can hide them, if necessary . . .

[unborn veldt]

yeah, it's not in the game manager, and it's also a pain to handle when the enemy dies (I'd have to delete it) and for other behaviours. Most of the tutorials I found use what I'm using.

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

like this

[sour fulcrum]

clicked that embed and got ai keanu reeves ad im gonna kill myself

[hexed terrace]

You can use more than one canvas

[unborn veldt]

as I said, the bar has its canvas in the prefab

[cosmic dagger]

You should be using 2d instead. When an enemy is spawned, instantiate a UI health bar and pass it the enemy information . . .

[naive pawn]

LookAt a position means it's rotated to that position, the center of the camera
you need it to look at the plane of the camera, ie its own position projected onto the camera plane

[sour fulcrum]

this tutorial is for a 2d game where there's no rotational depth, its not directly applicable to 3d games

[unborn veldt]

well another one (https://www.youtube.com/watch?v=cUQVLgohAjY) does the same, and it doesn't align the health bars

as you can see from the thumbnails

[sour fulcrum]

yeah?

[naive pawn]

im confused what you mean by this, could you elaborate what change you're proposing

[cosmic dagger]

They're just saying using 2d for the health bars would be easier since they already face the screen correctly . . .

[naive pawn]

that doesn't tell me anything new

[unborn veldt]

yeah what do you mean by "using 2d"

[naive pawn]

this is all in a 3d world, no?

[unborn veldt]

how am I supposed to just "use 2d" in a 3d world

[sour fulcrum]

i mean it was a response to you suggesting a world space camera

[naive pawn]

using 2d would not make them face the camera, they would face the XY plane

[sour fulcrum]

i said 2d when i should have said screen space

been a long day, apologies

[unborn veldt]

the object has a canvas, it doesn't seem like it's doing anythig. As far as I understand, it's because the object with the canvas is still in 3D

it's making me render image components, but definitely not fixing the problem

[naive pawn]

ah, you mean a screenspace/overlay canvas? yeah that makes sense
though it'd also mean all health bars would be the same size regardless of distance

[grand snow]

its not a great idea perf wise to have many world space canvases for some health bars btw

[unborn veldt]

...isn't there a way to just rotate the already existing bar correctly?

[naive pawn]

hm, why not? isn't the cost of a canvas from dirtying/rerendering them?
so having it all in a single canvas would make any health change/position change dirty the whole thing, no?

[unborn veldt]

everything works flawless but a single rotation

[naive pawn]

yes, i told you

[unborn veldt]

yea but I have no clue how to do it ahaha

[grand snow]

yes and we cannot benefit from things like gpu instancing as they are all difference meshes

[sour fulcrum]

batching can't be applied to multiple canvases

[naive pawn]

then ask instead of ignoring it lol

[grand snow]

better if they are all the same mesh + shader doing the health bar for batching benefits

[unborn veldt]

sorry, was focussed on all other comments too

[grand snow]

If it was done in one screen overlay canvas instead that would be a better option too (ideally its own canvas/sub canvas to not dirty other parts of the ui too)

tl;dr many canvases for a health bar in world bad

[sour fulcrum]

no batches?

[cosmic dagger]

@naive pawn by using 2d, we mean, using the UI canvas, not a 3d object . . .

[unborn veldt]

so, the player's UI where there's all the other stuff? As I said, this makes every other aspect harder, from instantiating to removing the health bar

[grand snow]

If its done in screen space UI it means you have to update their positions yourself (world > screen) but its cheaper perf wise

[unborn veldt]

@naive pawn how do I do what you said? It seems like nothing I do is working

[sour fulcrum]

Ideally ideally theres like shader shit you can do for tailor made situations right?

Like instead of talking to unity ui just drawing to screen yourself

[naive pawn]

im not sure if there's a more direct way to do this, but here's one way (should work afaik, but untested)
do WorldToViewportPoint on the transform position
set depth to 0 on the result
do ViewportToWorldPoint on that
look at the result point

[grand snow]

well yea you can just draw them via code with something like DrawMeshIndirect() if you want. works well with batching too

[unborn veldt]

Like that?

it's not working

[naive pawn]

damn.

how isn't it working though

[unborn veldt]

The bar is tilted as before (I forgot to invert the camera position so it's actually backwards, that's why it's grey)

ehhh I'm just gonna go with the boring and problematic UI solution if I can't tilt that bar, at this point it's easier to do that..

[naive pawn]

hmm, am i understanding this correctly?

1. updating a canvas element dirties the entire canvas, can be modularized with canvas groups
2. dirtying a canvas is expensive
3. multiple canvases updating is worse than the same elements on the same canvas?

[grand snow]

a canvas component can be used inside a root canvas to have smaller groups that can cause redraws
canvas graphic drawing uses batching so many health bars using the same textures/material should get batched together
this is why many single world space canvases in scene is shit

[naive pawn]

ah, i wasn't really familiar with batching

[grand snow]

Unity themselves recommend not having 1 canvas with everything in it and using canvases within to split up things

[naive pawn]

so separate canvases are much worse if they have the same assets, because that means batching doesn't happen?

does that also apply with 2 canvases that don't use the same assets?

[cosmic dagger]

I thought it was normal to use multiple canvases and keep the ones that constantly update in their own to separate from static UI . . .

[grand snow]

Yea that is right:
Main canvas:

• text
• text
• sub canvas
• • health bar
• • health bar

[grand snow]

My understanding of how canvases draw makes me think its not possible to ever batch them because it should be assumed that each canvas has unique content

frame debugger will answer these questions anyway, i know it will batch within a canvas (e.g. 20 images using the same spritesheet/sprite with similar draw order)

[naive pawn]

ah i think i misphrased my question

i mean between these 4 scenarios:
A1: 2 canvases both using asset X
A2: a single canvas having 2 instances of asset X
B1: 2 canvases, one using asset X, the other using asset Y
B2: a single canvas with asset X and Y

if both X and Y dirty the canvas, batching makes a difference between A1 and A2, but not between B1 and B2, right?

or i guess, batching will apply to A2 but not B2?

[grand snow]

I think only A2 will batch

[naive pawn]

well, that was a lot of words for a simple answer
i really need to get better at phrasing my questions lmao

[grand snow]

its a bit confusing. I just checked something in what im working on rn and 3 world space canvases with the same content are not batched but is in a "render sub batch" group

doesnt behave like when multiple graphics are batched in 1 draw call

            var zVelDifference = _currentVelocity.y - _playerRigidbody.linearVelocity.z;

            _playerRigidbody.AddForce(transform.TransformVector(new Vector3(xVelDifference, 0 , zVelDifference)), ForceMode.VelocityChange);
            


            _animator.SetFloat(_xVelHash , _currentVelocity.x);
            _animator.SetFloat(_yVelHash, _currentVelocity.y);
        }

}

Does anyone know why when my character moves he slides around and the proper animations don't play?

[wintry quarry]

The sliding is because you're using Lerp to change the velocity over time
As for the animation - I would check the console to make sure there are no errors. Aside from that i'd run the game with the animator window open to see if the parameters are being set properly.

[raw tulip]

Thank u man ily

[raw tulip]

How would you go about using the console to check if animations are working?

[wintry quarry]

As I said you would use the console to check that there are no errors

that's step one

[rough granite]

Wonder why people love lerp :?

[wintry quarry]

it's all they know and every hare-brained youtube tutorial uses it as a quick bandaid

[raw tulip]

I followed a tut, my 2nd day on Unity 💔

What's the superior alternative?

[wintry quarry]

it's not about alternatives

it's about what you are actually trying to achieve

[rough granite]

Nah fair not hating just curious cause I've never seen it work for character movement here

[wintry quarry]

If you want direct analog control without extra "acceleration", you shouldn't be using anything - just feed the input directly into the velocity (with some scaling factor)

[rocky canyon]

lerps and slerps are still solid
but you learn other things like SmoothDamp, MoveTowards, etc
all kinda have their own use-cases

and then theres Tweening Libraries (DoTween, LeanTween, PrimeTween etc)
may want to look into those at some point

[raw tulip]

Thank u, very insightful

[rocky canyon]

tweens can use "curves" and they have built-in functions for almost everything related to unity
positioning, rotations, scaling, UI positioning, single values, colors, rigidbodies, and the list goes on

i used to animate everything.. like a door that opened -> animation, a ui panel that faded in and out -> animation.. it wasn't until i was told to be cautious about animating my UI that i discovered it.. and for simple animations theres no better alternative imo

[barren pilot]

How/where can I store changing data?
Context: I am creating a game involving autobattle heroes. Each hero will have items equipped. Each item will have mods that can be changed through crafting. I am thinking of storing mod information as scriptableobjects, as mod information shouldn't change. I am a bit stumped on how to store the item information, as the mods on an item can change through crafting (e.g., rerolling a mod value within a mod-defined range).
I am hesitant to use monobehaviour because the items aren't really interacting with things in the game - they're more like data containers that are themselves stored in the hero they're equipped to or the master inventory.
But i am also hesitant to use scriptableobjects, which according to what i've seen online, are static, so shouldn't be able to store changing data.

[cosmic quail]

plain C# class

[frail hawk]

a json file or xml would do it too

[barren pilot]

Will the plain c# class need to be instantiated on a gameobject each time I generate a new item? or can i simply generate a new Item and store it like a variable in a hero/inventory?

[cosmic quail]

you can just store it in a list in your inventory class yes

or hero class

[barren pilot]

I feel this would be inefficient especially because of crafting during runtime - i envision changing the item multiple times a second during crafting, wouldnt it be inefficient to store it as a file? i would probably store it as json at the end of session

#1062393052863414313 for ECS related issues

[keen cradle]

Thx)

[red igloo]

I am making checkpoint system where the player enters the checkpoint trigger it should save the players position to the spawn point and the kill player collider should teleport the player to the spawn point. I have 2 scripts one will handle saving the players position to the spawn point and the other will teleport the player to the spawnpoint

[red igloo]

I was wondering how I can save the players position to the spawn point. here is what I got so far https://paste.ofcode.org/36Es8rH7jccPk5pmKDgFvb5

right now if I enter the checkpoint trigger it will teleport the player to the spawn point which I want but I only want it to teleport when I hit kill player collider

[cosmic dagger]

You immediately assign the player position to the spawn point (that's why it moves right away). You should store the current checkpoint (if it's a MonoBehaviour component) or the spawn point Transform as a separate variable, like currentCheckpoint or currentSpawnPoint.

When the player dies, assign the player position to the currentXXX variable . . .

Basically, you only want to store the spawn point position when you reach the checkpoint, then use that position to set the player there when they respawn . . .

[red igloo]

what like currentCheckPoint = spawnPoint;

[cosmic dagger]

Yep . . .

[red igloo]

so in the other script thats attached to the kill player collider should I do
_player.positon = currentCheckPoint.position

this is what I have for saving the checkpoint https://paste.ofcode.org/GMJiDbkCg85FXy4XMgVj6B

when I try to reference the currentCheckPoint.position it doesn't recognise it.

[grand snow]

If you have many Checkpoints this wont really do anything useful
It should be that the checkpoint script updates something on Player so it knows what the latest checkpoint is

then on death it can check if its not null and move position to the checkpoint pos

[red igloo]

how should I do it? Imm gonna be having more checkpoints later on

[grand snow]

yea i said the same thing?

[grand snow]

the checkpoint script should do something like:

[SerializeField]
int order;

private void OnTriggerEnter(Collider other)
{
    if (other.TryGetComponent(out var player))
    {
        if (player.checkpoint == null || player.checkpoint.order < order)
        {
            player.checkpoint = this;
        }
    }
}

then in your player script on death you can do transform.position = checkpoint.transform.position; (if not null)

[red igloo]

like this?

[grand snow]

yea. Ideally it would be done via a function on TeleportPlayer but looks good

[red igloo]

I just tried it and it doesn't work

[grand snow]

er actually your second picture shows a logic problem

the "checkpoint reference" should be stored on the player object

the death area trigger can tell the player to move to the last checkpoint

[red igloo]

what like create a separate script that has the reference and attach it to the player?

[grand snow]

up to you. If you have a main "Player" script to handle stuff like this it can go in there:

void UpdateCheckpoint(Checkpoint newCheckpoint);
void RespawnAtCheckpoint();

[red igloo]

should I put this in the update method?

[grand snow]

no its just an example of the functions you could make 😐

[red igloo]

This is soo confusing if I were to put the functions in my script what would I say in them? im just getting random errors

I feel like you are way over complicating this

[grand snow]

public class Checkpoint : MonoBehaviour

    private void OnTriggerEnter(Collider other)

            player.UpdateCheckpoint(this);
        }
    }
}

public class Player : MonoBehaviour
{
    private Checkpoint checkpoint;

    public void UpdateCheckpoint(Checkpoint newCheckpoint)
    {
        if (checkpoint == null || checkpoint.order < newCheckpoint.order)
        {
            checkpoint = newCheckpoint;
        }
    }

    public void Respawn()
    {
        if (checkpoint != null)
        {
            transform.position = checkpoint.transform.position;
        }
    }
}

public class RespawnArea : MonoBehaviour
{
    private void OnTriggerEnter(Collider other)
    {
        if (other.TryGetComponent(out var player))
        {
            player.Respawn();
        }
    }
}

have a complete example

plz try to understand the flow of logic as you seem to have a hard time understanding

[rough granite]

This is still over complicated

[grand snow]

its really not

[rough granite]

Right but you could do this same thing is less

Meaning it's over complicated

[grand snow]

This is what I deem to be good design so you do you

[rough granite]

Also your player class doesn't have a variable for order

[nova kite]

how is TBOI's random generative rooms work? because it's not fully random so it's not picking from a pool of enemies but it's random enough to not be the same every time

[grand snow]

yes there is a mistake in there, fixed

[crystal rain]

Does anyone know how to get past a hidden code system

[timber tide]

konami code

[polar acorn]

What?

[polar acorn]

Ask a stupid question get stupid answers

[eternal needle]

there is literally nothing over complicated about this. this is about as basic as c# gets.

[crystal rain]

I was just wondering how to get past a software that is blocking me from seeing how there code works

[polar acorn]

Yeah, as I said, stupid questions get stupid answers

[crystal rain]

But it wasn’t really an answer

[eternal needle]

you'd want to maybe ask in a place related to this game. this isnt really unity related. sometimes games have docs that describe how their features work

[polar acorn]

It also wasn't really a question

[crystal rain]

How was that not a question?

[polar acorn]

Provides zero information and is fundamentally unanswerable

[crystal rain]

You could have just asked for further explanation.

[polar acorn]

Nah this way's more fun

[south nexus]

hey im trying to make a top down rpg game and im pretty new to coding so ive mostly been following tutorials and stuff but im having issues on how to make enemys attack where the player is like for example playing the attack down or up animation depending on where the player is. is there any tutorials or information about this?

[crystal rain]

Ok so it was all rage bait 👆nice 😏

[rich adder]

if you're new, your first project should not be rpg

there isn't going to always be a video for how to do this and that, it takes years of experience

[eternal needle]

which part do you struggle with? which part exactly of the attack are you trying to implement

[crystal rain]

Try starting with coding movement if you have not already or coding item mechanics

[south nexus]

yea ik but im keeping it pretty simple just to learn the basics

[south nexus]

well for example flipping the hitbox and playing different animations depending if the player is up or down and just figuring out what the most efficent way to code it is with out running in to problems later

[crystal rain]

I am decently new and I was wondering what coding software I should use

[eternal needle]

i dont know what you mean with "depending if the player is up or down". up or down relative to what?
also you dont need to manually flip the hitbox. have it as a child of some object in your character and itll move around along with the animations.
Before you worry about doing this efficiently, first worry about doing it once. there isn't really a way to do animations more efficiently, at the end you're going to be interacting with the animator component anyways. You would typically just want to be interacting with it through one central script and thats fine enough

[rich ice]

you mean which !ide ?

[eternal falcon]

Yes

I am on Mac so idk what to use

Because most of the systems are windows

[rough granite]

You can still use visual studio no? The first option when you click on the manual install for visual studio is for mac

[crystal rain]

It says visual studio code not just visual studio

[rough granite]

What?

[ivory bobcat]

https://learn.microsoft.com/en-us/visualstudio/releases/2022/what-happened-to-vs-for-mac

For the most secure, up-to-date experience, we recommend either Visual Studio (Windows) or moving to Visual Studio Code on the Mac.

[ivory bobcat]

Those are the available coding software. You'd pick one from the selected where the first two are the same but simply different installations.

When my rigidbody player steps on uneven terrain, say a slope, or jumps on a box, he starts rotating jitterely on his own in turn causing my camera to rotate. Anyone have any ideas? Does this sound familiar?

Did you fix it?

[teal elk]

How do I properly parent items to a player joint without a weird rotation and pivot point , so they tem can look proper with my animation

[edgy pier]

What is it exactly youre trying to achieve?

because if it's specifically this box, I'd say you need a box carrying animation.

[raw tulip]

No, I'm about to post in code-general 💔

[edgy pier]

Anyway If you do get that specific Box Carry animation I'd go for a dedicated carryslot.
So basically an empty gameobject where you place the box instead of setparent, you get some control over where the box spawns 🙂

also I would cache your meshcollider component.

[raw tulip]

I posted it

[edgy pier]

We need some more information on your movement.

how are you doing movement? Character controller? do you have animations that do physics.

[raw tulip]

#1398437612338937947 message

I posted the script here

[teal elk]

i have the animation. What I mean is when I parent it, I want it in a specific position, but I don't understand Unity transforms properly to position it the way I want. In the code, I'm setting the parent to my rig prop joint transformation, but the crate is under the floor when parented and with rotations.

[edgy pier]

its because you dont change the transform, you just set the parent.

so the box is being dragged through the ground

you can do SetParent(transform, false)

(you can overload the method, if you do not the worldPositionStays param is set to true)

https://docs.unity3d.com/6000.1/Documentation/ScriptReference/Transform.SetParent.html

[livid canopy]

guys i need help with a script that can move a car properly

where can i find one?

[edgy pier]

asset store

[livid canopy]

does it cover all the movement of a car ?

[edgy pier]

I bet you can find insane assets on the asset store that do that.

[livid canopy]

ok thanks for the info i have never searched in the asset store

[wicked cairn]

Any idea for VS ide resizing this area? it automatically went wide

[nova kite]

Oh not every feature could be re coded in Unity?

[eternal needle]

im not sure how you got that from what I said. I meant that you're asking a unity server about how a very specific game writes its logic. It's incredibly unlikely that anyone here knows, and even if they do, this would be better in a forum/server dedicated to that game

[edgy pier]

I bet it can be recreated, but I also think not a lot of people know what game you are talking about , thus dont know how it would work.

ooooo you mean the binding of isaac.

[sour fulcrum]

bawsi is correct but here's a few general pointers on that kind of thing,

re: floor design i'd take a look at this https://youtu.be/Uqk5Zf0tw3o?t=97

for items, consumables, enemies etc. i'd assume they use spawn pools that consist of a list of weighted rarities

weighted rarity is a lottery esque random system where a given option has a amount of lottery tickets and the random selection is done by randomly picking one of those options

eg. lets say a given floor type had a enemy spawn pool of

CoolGuy1 | 4
CoolGuy27 | 4
MomsHand | 1
RarerCoolGuy4 | 1

the total spawn pool has 10 choices it could randomly pick from. Weighted rarity pools are used a lot in these kind of games because you don't neccarily need to adjust all the options values whenever you add or remove something, you just need to give whatever your adding a value thats relative to all the other values

[dire agate]

Can i update .assets files from previous game versions to current by myself?

[grand snow]

sounds like modding stuff which we dont help with
once a project is built thats it

opening an old project in a new version will prompt to upgrade so its all done for you

[quiet pilot]

idk if this counts as coding but how would I actually make this show the texture?

I've tried it in both 2d and 3d

I'm trying to follow a tutorial (this is just an example they gave to start out with) but they don't explain this

[wintry quarry]

you need to hook the output of your multiply node into the Base Color node in the Fragment Stage

(in the top left)

[quiet pilot]

thank you so much that took way too long

I spent hours trying to figure it out before I remembered this server 😭

(I might be stupid)

[nova kite]

Yes haha

[nova kite]

Well it doesn’t have to be specific to that game I’m just asking about the logic in general in terms of Unity functionalities because I only learned the Unity game engine

[sour fulcrum]

Unity doesn't really offer any specific ways to help do that stuff

[nova kite]

This is exactly what I wanted thank you so much❤️ super interesting!

[nova kite]

It’s logic you’d have to create yourself then I assume?

Well as long as it’s possible haha

[sour fulcrum]

Anything is possible 😄

[eternal needle]

if you're asking about the generative rooms specifically then yea you'd ideally want to look at resources online. it seemed you were asking more so about that game and the part about "it's not fully random ... but it's random enough" which isn't possible for us to answer

[nova kite]

I did a prototype with spawn handling but it was a mess and got too laggy, not sure how games manage to have 100s of entities without lag, are there special mod tools for Unity you’d have to install for it?

[sour fulcrum]

your using the term mod in a way that probably gives that message a different meaning btw

[sour fulcrum]

short answer is kind of skill issue respectfully aha, there's many ways you can improve that kind of thing

if you get back into that "mess" feel free to ask about it when you have specifics to show

[nova kite]

I see so it’s a very specific case for that game, I’ll look further into the specifics thank you❤️

[nova kite]

I meant like maybe a Unity package that is downloaded into the project kinda thing

[nova kite]

It’s a very simple spawner objects that pastes prefab instances into the scene

[sour fulcrum]

yeah package/asset/template more applicable term there, only nitpicking because you'll have an easier time finding them with those keywords

[nova kite]

And it gets very laggy, I basically re created one of those fake ad games where you shoot hoards of enemies

[sour fulcrum]

Well in that example is it the spawning of the enemies that is laggy or what the enemies are doing once they are spawned? Both can be problems

[nova kite]

They are just walking forward but I assume because each has a movement script to find the player and move towards him maybe that causes the lag(?)

Because it runs hundreds of scripts

[eternal needle]

game obejcts wasnt meant to really handle 100s of characters with their own logic. there are optimizations you can try to make, possibly using jobs, though this isn't beginner territory at all

especially if this is mobile

[nova kite]

Ohh I see, so it’s more complicated Unity functionalities

[sour fulcrum]

Yeah so overall the problem is when you do things at scale, the cost of doing certain things is going to matter a lot more right. So there are many, many ways to improve this kind of thing that usually fall under

1. Doing things less
   1.a. - Doing things less by caching values in order to avoid "expensive" code when you can
   1.b. - Doing things less in a literal sense, eg. if your enemies are constantly checking something (maybe a path to the player) don't do that every frame, do that every x frames or something
2. Doing things faster - Just Unity/C# ways of doing the same thing in a more optimised way
3. Doing more at the same time. - By default a majority of Unity code runs on a single cpu thread. You can kinda compare this to someone with 1 arm working a busy kitchen, at some point the bottleneck is just how much the chef can do. Using pretty advanced programming knowledge you can mess with stuff like burst, jobs and ecs in order to multithread your code in order to utilise many threads, but there's a lot of considerations on how to do that

[nova kite]

Ooo I see! Thank you both for all the information super useful!❤️

I’ll look into all the suggestions

I didn’t know it runs on only one thread, is there a way to utilize more?

[sour fulcrum]

with scary code like jobs as bawsi suggested, it's probably not going to be the first tool you bring out

[nova kite]

Ohh that’s what jobs do!

[eternal needle]

you're pretty limited to what you can do on other threads iirc

like i dont think you can access most of the unity api on another thread

[sour fulcrum]

hordes of enemies moving towards the player is something jobs can mess with pretty well though right?

[nova kite]

How do companies make AAA games on Unity with only one thread?😅

[eternal needle]

i dont use anything advanced like this so i dont really know. I just remember seeing guides out there that did do this

[eternal needle]

some use #1062393052863414313 which are quite advanced. some dont start off by designing their game around having 100s of enemies

you'll see a lot of games really dont have that many enemies at once, for a reason

[nova kite]

Ohh right offloading

[sour fulcrum]

Yeah I haven't touched any of it directly yet but I read up a tiny bit last month and it's actually way less intimidating than i thought

[nova kite]

Does it kill game objects when you offload areas?

And if so are you able to save their state so when you load them again they remain in that state?

[sour fulcrum]

theres no single answer for either question

thats up to you

[nova kite]

I see so that’s possible too,

Right everything is possible🤣

[sour fulcrum]

I have a UnityEvent esque class named ExtendedEvent that wraps an action and I want to make a kind of middleman class that allows strangers to listen and unlisten but not invoke, any suggestions on what to name this kinda class?

[shell sorrel]

use a interface

expose only the interface that can sub to it

and only invoke on the concreate type

[wintry quarry]

a kind of middleman class that allows strangers to listen and unlisten but not invoke
This is how regular C# events work

[shell sorrel]

or just use C# events

[sour fulcrum]

Can't they choose to cast into the full thing though? I did see thats how ireadonlylist works though so i might be missing something

[sour fulcrum]

Yeah but i like my wrapper

[shell sorrel]

sure if they have access to the type

[wintry quarry]

What goal are you trying to solve? Absolute security or just a convenient API?

[shell sorrel]

it could be internal or private

also they prolly wont

so its fine

also C# events literally do this

just use them

[sour fulcrum]

convenience more than anything but I wouldn't mind just a little bit extra security

if interfaces are the objective answer here i can live with that

[shell sorrel]

you can't toss around words like security with no context

[sour fulcrum]

(they brought up that term)

[shell sorrel]

no matter how you do it, people can still blow past any guard rails you put up

[sour fulcrum]

I'm very aware

[shell sorrel]

but you can expose something via interface even if its own protection level is lower

which would stop casting to it

still not going to stop meta programming stuff like reflection

[sour fulcrum]

Yeah

[eternal needle]

if you use an interface though, something will have to implement this interface along with the event. I don't really see the point of it. unless im misunderstanding they just want a class with a private unityevent inside, with an add and remove listener class. Though I dont see the point of this either

[shell sorrel]

public ITriggerable<Transform> OnTargetChanged => _onTargetChanged;
private readonly Triggerable<Transform> _onTargetChanged = new();

is how most would do it via interfaces

like mentioned depending on your needs the concrete type could be internal or private

but it only really effects ergonomics and intent of how its used, can smash through that with reflection easily

[eternal needle]

truthfully this just seems like a waste to do. you have to use this custom interface/class/whatever everytime instead of a unityevent just to protect yourself against calling Invoke on another object. If you were working with someone, you'd also have to convince them to remember this as well. Nothings stopping you from using a unityevent directly 3 months in the future because you forget about this class, and making this whole thing pointless

theres really no need to protect yourself from this, in the same way you dont need to protect yourself from the fact any code right now could call Application.Quit or Destroy every single object in your scene for fun

[sour fulcrum]

Forsure, I just wouldn't have minded a lil' bit extra. If it doesn't work out that's life 😄

I hear you on concerns about it being a waste of time but i've used my one personally quite abit and im happy with it

we chilling

[shell sorrel]

am just confused by you saying security

[sour fulcrum]

(i was not the one who brought up the term security)

it's chill

[shell sorrel]

but yeah for custom implementations like what i showed a few nice things can be added in, like the one at work we have instead of unsubcribe methods you just returns a IDisposable on subscribe

which can be nice for only being subbed for a certain scope, or nice simple by just putting them all in a collection on sub, then disposing them all in this objects dispose method

[shell sorrel]

#💻┃code-beginner message

[sour fulcrum]

dawg

[shell sorrel]

the downside to not using event is other people will likely not clue into there being a other implementation to use

[sharp solar]

what does it mean when you say security in a context like this

that you want to be sure what can and cant be called or changed externally?

[shell sorrel]

the only non interface way i can think of is a little awkward as well since its just abusing closures and would involve making a method that returns both the thing to sub to and a method that invokes through it

[wintry quarry]

it doesn't really mean anything. Just compiler-enforced prevention of something

but anything like that is easy to get around if someone really wants to

I was basically wondering why the person cared if someone could cast the interface to a concrete type.

[eternal needle]

a class with a unity event and a public AddListener/RemoveListener method is what i imagined they have

rather than a class inheriting from UnityEvent

[shell sorrel]

yeah i almost never use actual unity event

[eternal needle]

same, I got lost once really badly when my main menu was connected entirely via unity events and decided it was better to just do it through code

[shell sorrel]

to me its just overhead and they really only have benefits if you are using mb's or so's everywhere which is often not that case

[median hatch]

is unity down or am i tripping?

giving me internal server error

[sharp solar]

idk

[median hatch]

yea wtf

[median hatch]

cant enter my project

[sharp solar]

lucky im already in mine 😎

[median hatch]

hope yours isnt 15GB

asset store seems to be slow asf too

[rough granite]

ima be honest 15gb isn't much for a unity project

[median hatch]

dont give a fuck if its big or not

[sharp solar]

lmaoo

[rough granite]

ok buddy go take a chill pill if your gonna be pissy

[median hatch]

pissy?

[sharp solar]

🗣️

[median hatch]

instead of giving proper info youre here having a dick contest

[sharp solar]

yzaka u funny bro but people around here are very serious just dont get yourself kicked or nothing

[median hatch]

i've been here for a long time

i know how this works

[rough granite]

not like you've given any context as to why you can't enter your game, plus this is the code channel not the unity project not working go to #💻┃unity-talk or something not here

[rough granite]

@sour fulcrum context i think idk

[sour fulcrum]

your just getting the wrong vibe i think ngl

[median hatch]

idk some people are just eh

im getting this error when trying to sign in in unity hub

[obtuse yoke]

yes

[median hatch]

wdym

are you getting the same thing?

[sharp solar]

nah they just agree that youre getting the error

[obtuse yoke]

yes

[rough granite]

nope https://status.unity.com/

        public IListenOnlyEvent<T> OnSelected => onSelected;
        public IListenOnlyEvent<T> OnUnselected => onUnselected;

im happy enough with this

[median hatch]

hmm weird stuff

tried restarting pc but still the same

[rich ice]

tbf, that site can be a little inaccurate sometimes. issues can take a few minutes or a few hours to be reported

[obtuse yoke]

im trying to do mp stuff on the cloud, i am getting the same error.

[median hatch]

well if youre also getting it then its probably on their side

[obtuse yoke]

that's why im here, looking to see if i was alone.

The fact you are also getting it reassures me.. although i wonder if i caused it.

[median hatch]

yes it was definitely you

xD

[obtuse yoke]

its a possibility.

somewhere in multiple datacentres, servers are burning.

..i mean i blame them, they gave me the free 'credit' to spend

[median hatch]

guess it wasnt free after all

[pallid heron]

C# thing, not a unity problem, but I REALLY REALLY REALLY REALLY wish there was a way to say "All declarations between HERE and HERE have THIS set of attributes"

I just felt the need to complain about that

[sour fulcrum]

real

[eternal needle]

i might be remembering wrong, but I think it works when you declare variables together of the same type.
like int a,b,c;

though yea that doesnt seem to apply much in your case

[pallid heron]

You are remembering correctly, I use that all the time.

[wicked fiber]

Is it possible to make my game object to only sense collision on the frame it was made?

[rough granite]

on the frame the object was made or the frame the collision happened?

[wicked fiber]

the frame it was made

i wanna use the collider when its made and then use it for other purposes on other frames

just to specify

If it's not possible I can find another way, but it would be easier for a built in way

[teal viper]

Might be better to use a physics query, no?

If you really need to, you could store the frame number in awake, and then disable the collider in update on the next frame.

[wicked fiber]

Alr thanks

I honestly forgot about queries though

[rough granite]

surely you are in the wrong server

[frosty hound]

@humble rain There's no off topic here. Thanks.

[humble rain]

where do i ask that kind of question ?

[frosty hound]

Not in this server, that's for sure, being that it has nothing to do with Unity development.

Hi
Anione can explain me how I can make move control for the player 2 in my scene with the new input system
I am creating a simple pong and I need to move the player 2 with your specific 2nd console gamepad
when I move the player 1 the player 2 is moving too

[brave robin]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.5/manual/PlayerInput.html

#🖱️┃input-system can help with further questions

[frigid sequoia]

I am looking at the screen for a while trying to make a not shitty solution to this. So I have all those stats that can be added as stats from the gear and I want the UI to go over all of them and display a text showing those that are not 0, but I am not sure how to do that iteration/loop to check them all. Should I just manually go 1 by 1?

Or should I try to make them into a list somehow, even tho they are diferent data types?

[teal viper]

You could make a Stat class that contains a string for the stat name and a float/int for value. Then create a list of these stats.

[frigid sequoia]

I kinda have that already, but I'd have to refactor all of the above???

[night raptor]

One could also use reflection, but I wouldn't generally suggest that for runtime code

[frigid sequoia]

Yeah, also thought of that, fast to code, but rather slow to run

[teal viper]

yep

[frigid sequoia]

This is gonna be update whenever a the selected inventory changes

[eternal needle]

well you basically wrote it in 2 different ways. You have this defined StatAttribute and then did not use it to define the stats in the class above

[teal viper]

might be a good task for AI

[eternal needle]

Whats in your Stats enum?

is it the same name as all those fields

[frigid sequoia]

Kinda the same, yeah

I was not intending to iterate over those when I was making the stats tbh

Just to each value add the extra value from the modifiers

[eternal needle]

id consider even just having a Dictionary then of <Stats enum, float>

anything that wants to access a stat is forced to do so by its enum

all of those could be floats realistically

[frigid sequoia]

Pretty much any number I am using could be a float I guess

But I just went for the "this value can NEVER have decimals" route

[night raptor]

Unions maybe?

Wait are those not supported by C#?

[eternal needle]

i guess depending on the game design it could get awkward. id still try to keep it as a float and round it when its used, if thats required.

[frigid sequoia]

Realistically I should kinda just use this for everything, but it would take some significant changes now considering how many stuff is referencing that and how different it would be

[eternal needle]

the main thing I wonder is how you're using that StatAttribute in the first place

is there somewhere that uses a switch statement from enum and manually affects that class.health?

[frigid sequoia]

And it's not like a 1 to 1 conversion, some attributes don't even show on the "Stats" enum; since I need to use some "in-between values" on the stats to do the final calculations and all that do not show there cause they were intended mainly just to use for stats that are displayed

[frigid sequoia]

The use they were made for is to basically show in here when making gear, so I can add stats 1 by 1, instead of having a whole list of all the stats when they are gonna just use like 1-4

The GearManager takes that on a switch and converts it into the appropiate stat and adds it to the total

But the GearManager is indeed just having all stats on it straigh up

Having some stats locked into ints make it so even if I wanted to pass a float I could not, so it's kinda of a remainder here

[eternal needle]

yea thats what I was wondering. unfortunately the best thing here would be to refactor but tbh it shouldn't require other systems to massively change code. Are you by chance directly referencing gearManager.health and other values in other scripts?

[frigid sequoia]

Well, basically the final stats of the unit is going over each stat, adding the base, modifiers and gear and get the final result with that, so yeah, they are being referenced

[eternal needle]

the refactor would be easy if you had methods exposed to handle the logic you want. A TakeDamage method where GearManager handles subtracting from its own health would mean your entire change would be

// in gear manager
public void TakeDamage(float dmg)
{
  // health -= dmg;
  statsDictionary[Stats.Health] -= dmg;
}

but now if you move this health variable to a dictionary, a lot of other scripts are going to have errors

or even like a GetStat(Stats myStat) method would save from all other scripts referencing the actual floats

[frigid sequoia]

Well, the thing is like, health is not even a thing?? Like, health on the stats enum is basically refering to maxhealth, since health on itself is not a stat, really

The stats on the unit calls that "currenthealth" instead, and is not modified by any stat

[eternal needle]

then make it a value in the stats enum

[frigid sequoia]

So it's kinda convoluted to change

[eternal needle]

either way that doesnt really affect the concept here, refactoring would be easier if you dont directly reference the public variables. now that you consider putting them in a dictionary, everything breaks

if you really cant refactor it due to an absurd amount of changes, in your initial problem, id suggest write the code one by one because this wasn't designed to be iterated over

[frigid sequoia]

Yeah, like I think I would get more issues than solutions refactoring tbh

I am not even sure if it be technically better, maybe easier to code, but, would also make it kinda more complex and messy?

Like basically I think I would get like genuinely hundreds of errors changing how stats are referenced now lol

[eternal needle]

I feel like you could get away with some slight insanity here if you really wanted to refactor this. Like in GearManager (is this your stats class?), create the dictionary, then change currentHealth to be a property.
currentHealth => myDict[Stats.CurrentHealth];
then rename it using IDE to follow proper convention

[frigid sequoia]

Ah, well, no, GearManager just stores the stats comming from the gear rn

Then the class Stats, should handle them comming over to calculate the finals

[eternal needle]

nah it would definitely be better. right now it feels like you're inbetween both worlds where you reference a stat by this enum, but they're also referenced directly in the Stats class

i mean, what you're doing can work, but you already see that its not possible to iterate through

[frigid sequoia]

I also have a separate class that is basically a copy paste from stats that is BonusStats, that is basically any modifiers from stats that do not come from gear, I placed these appart so I could reset any bonus directly if needed

[eternal needle]

i think i have pretty similar code to what you're doing here, though it is a bit odd that you handle the death logic there. I can show how the dictionary works here

[frigid sequoia]

Yeah, but cause honestly, when I was placing stats, I was not thinking at all about the iteration, it only came to mind when I had to start making the UI and displaying them

Honestly, the only real reason why I would prefer an iteration here is cause I want 1, to not show stats that are not being modified by gear (aka = 0), and 2, I want stats that are going into the negative to display after the ones in possitive, so just going 1 by 1 is kinda more messy than anything I was doing with those prior

[eternal needle]

    void OnTakeDamage(DamageDealt damageDealt)
    {
        float newHealth = damageDealt.postDamageHealth;
        float maxHealth = playerStats.GetCurrentStat(StatDefinition.MaxHealth);
        float percent = newHealth / maxHealth;

        ChangeImageFill(percent);
    }

the only thing that changes is that I call a method to get the stat I want, rather than directly referencing it. you could've also implemented it this way from the beginning where it goes through that switch statement you mentioned. So your code would be some stats.GetStat(enum). The refactor from a bunch of fields -> dictionary would only change the implementation of GetStat

you still could do what I said above to make refactoring easier by changing what currentHealth is, making it into a property. You wouldnt need to go into other classes to change it

[frigid sequoia]

So, I would add that into the stats enum?

Feels kinda weird, considering that should not actually show in many of the things that are using it

Like what, can I now add "current health" as a gear attribute?

[eternal needle]

well for currentHealth specifically thats up to you, idk what you intend to do there. I actually do have currentHealth in my dictionary of stats

for other variables like maxHealth, the same concept still applies

[eternal needle]

i get what you mean where nothing is stopping you from doing this, but really this is something you would just avoid because you know it doesnt make sense. The same way that nothings stopping you from inserting 1000000 for your movement speed.

[edgy pier]

Gear as in.... items that are wearable /affect the player, right?

[eternal needle]

there are benefits though, like if we think of a "health potion" vs "mana potion". you wouldnt want separate code where both do the same logic, but are different methods because one needs to reference stats.currentHealth or stats.currentMana.
this could just be an enum exposed to the inspector and consolidated into one method

idk how i forgot to mention this. the main purpose for the dictionary is that you can "choose" a stat via the inspector, since enums are serialized. So if you had an object which buffed a stat, you just choose the enum in inspector, then pass that enum when interacting with the stats class

[frigid sequoia]

Makes sense but... I don't think it works on how I am doing things actually

Like for modifyig the stats, it would be useful to just select the stat as enum and add a value, but the managers need more data from that in most cases

Like for example, if it's a buff, it needs to know stuff like it's stackeable or how does it stacks, so it kinda needs to be of spefic class for that???

I think I could maybe refactor that too, if I try hard enough

Maybe I should???

Not sure

[sour fulcrum]

It's possible using scriptableobjects as kinda enums here might be a nice solution

depends on if that additional data is per gear type (enum option) or per usage of the enum

[frigid sequoia]

Currently not intend into making anything "usable" or "consumable"

Like at all

Could be cool, but no, I am trying to avoid that

[sour fulcrum]

you misunderstood what i meant by that

[eternal needle]

im not sure how this is affected from what im saying. the change im suggesting is that this Stats class should just use a dictionary<enum, float> and thats all. nothing else would need this dictionary

your buffs could stay exactly as they are

[frigid sequoia]

No, no, it would not affect that, I mean it would not really make me in this case make less classes, I think

[eternal needle]

it shouldnt affect anything at all

[frigid sequoia]

I still don't really get what you mean actually

[eternal needle]

infact if you do the cursed suggestion i said above of making all the current floats into properties, all the other code could stay the exact same

[sour fulcrum]

if you need more data in the enum options (eg. if a given enum option needs some int that says how much it could be stackable), you could use scriptableobjects in place of the enum

[eternal needle]

tbh i dont think scriptable objects solve anything here compared to enums

if there was some additional logic you needed to attach to this, then maybe, but that is also fine to just throw in a switch statement in the stats class.

[frigid sequoia]

A property like, an enum + value as you were saying?

[frigid sequoia]

I, could yeah, would kinda be in the same place tho? Maybe I am getting this wrong

[eternal needle]

i really dont like that im even suggesting this, but its purely to not break every other class. it would just be something like this

public class Stats 
{
  Dictionary<SomeEnum, float> myStats = new(); // plus logic to populate this dictionary
 
  public float currentHealth => myStats[SomeEnum.CurrentHealth]; // or => GetStat(SomeEnum.CurrentHealth)
  public float GetStat(SomeEnum myEnum)
  {
    return myStats[myEnum];
  }
}

also typed it on discord incase theres some error i dont see

then you could right click in IDE, rename currentHealth to CurrentHealth to follow convention for properties and itll update everything for you

[frigid sequoia]

So basically whenever I reference current health, it just gets me the value on the dictionary that is asocaited to the same enum and I can basically just get a stat with the method to do the same with any

I see, I see

I see what you meant now

Yeah, that sounds reasonable

[eternal needle]

tbh it's not even bad to do with properties here, but its just not what i'd do. you will have a lot of extra properties

because its not just currentHealth. it is everything that you showed in the initial screenshot

[frigid sequoia]

Yeah, there are a lot of little things than I am likely gonna miss and break everything lol

[eternal needle]

well with what im suggesting, you dont need to touch any other class yourself

everything is purely within this Stats class

currentHealth gets changed to a property so everything referencing it still works. Then IDE renames it for you

[frigid sequoia]

I am right now just considering how much better it would be going forward if I just do it that way, to see if it's worth the hassle

Mmmmm... not sure

[vital vault]

how can i change material properties from script

i want to change offset on unlit texture

[eternal needle]

actually, one thing i just realized is it will break if anything tries to set currentHealth from outside. you shouldnt be doing this anyways, but still thats something i didnt consider

[eternal needle]

you can get the material through the renderer, then look at the docs for Material and search for "offset"
https://docs.unity3d.com/ScriptReference/Renderer-material.html

[vital vault]

why i need to find it? cant i just serializefield it

[sour fulcrum]

if you want to change it from a script

you need to change it from a script

[eternal needle]

The renderer has and uses the material

[eternal needle]

Also to clarify on my last message, it would work if you had a setter for the property instead of only the getter as i wrote. Then youd also want a SetStat method

[rough sluice]

Player is falling forward like a mannequin when I try to move it forward by pressing W but instead of moving in that direction player just falls in that direction? Is this due to I am using 3D box collider?:
Codes:

private Rigidbody player;

private void FixedUpdate()
{
    Vector2 moveInputs = mobileInputs.Player.Move.ReadValue<Vector2>();
    float speed = 5f;
    player.AddForce(new Vector3(moveInputs.x, 0, moveInputs.y) * speed, ForceMode.Force);
}

[naive pawn]

we can (on desktop), but it'd be better with the ideal method as given above

(the pastebin sites would be better for large blocks like this though fyi)

to run forever, and after thats done
how do you expect this to work, exactly?

if it runs forever, it's not gonna be done

[restive sigil]

Yeah see the commented out piece of code in the

actual loop

theres a condition

[naive pawn]

which... isn't being used

[restive sigil]

yep

it runs only once

and for debugging i put it forever

and still only once

[naive pawn]

ok so right now it should run forever, but it's only running once?

[restive sigil]

yep

[naive pawn]

so you're only getting the VAL: log once? or are you also seeing the Anim End? log?

[restive sigil]

nope

it is 3.0 => 2.99998 or something

[naive pawn]

what's telling you that it's running once, exactly

[restive sigil]

unity is compiling scripts

it was so much better when that happened in the background in 5.x...

(used that ver once)

VAL: -3=>-2,999998, (-3.00, 1.00)

[sour fulcrum]

That didn’t change

[restive sigil]

i remember that it didnt put a popup which blocked my path

whatever

[naive pawn]

you still haven't answered this

[restive sigil]

the output.

its only printed once.

it should clearly repeat the loop

[naive pawn]

are you getting the Anim End log

[restive sigil]

again, nope

[naive pawn]

bruh i asked you 2 questions before and you said "nope" once LMAO

make sure you don't have collapse enabled in console

[restive sigil]

not enabled

and i know this because button isnt pressed.

[naive pawn]

any errors or anything else? have you tried putting logs at the start/end of the loop?

[restive sigil]

https://paste.mod.gg/boyrltxfjykh/0

imma run this

right i had to go

imma run it..

For some reason i am only getting the VAL thing and none of the other prints, which makes no sense

[runic lance]

you're not getting "Alive" or "Done"?

[restive sigil]

nope

and unity also flags the yield return null in the loop as unreachable now

why would a debug log stop that iteration

[runic lance]

well, either you're not running the code you sent or you're filtering the debug logs somehow

[restive sigil]

this is my player gameobject set up

i have an additional gameobject for rendering a sprite and a camera as a child of this

the actual sprite is being billboarded so i assumed that might have something to do with it but apparently it does not

[restive sigil]

If anyone wants to do my question:

Alive
AnimRoot Start.
Anim Start.
ANIM VALUE: -3=>-2,999998, (-3.00, 1.00)
Done
is my output
(scroll up)

[rough granite]

Change continuous to discrete

[solar hill]

same thing

in fact i changed it initially from discrete to continous thinking it would solve it

the fact that you can sort of bounce off of the wall makes me think some kind of collission is happening

but for whatever reason continous movement seems to just disregard it allowing you to walk through

tried it on different kind of colliders as well and you can walk through pretty much anything no matter how big or small

[rough granite]

Oh wait dont use Time.DeltaTime for rigidbody especially if it's in fixed update

[solar hill]

hmmmm for some reason

changing interpolate from interpolate to none

makes it work 🤔

[rough granite]

Odd cause I've been told when watching videos that it just makes the movement visually smoother

[solar hill]

but im using fixeddeltatime

not just deltatime

[solar hill]

well without it the collission works but uh yeah its less than smooth now

[rough granite]

Idk it's what the others here say :/

[restive sigil]

This works properly and loops if i remo remove the yields in AnimRoot(), but its not running in the background, and rather stopping the main thread......
But yeah, i want it to work separately

[naive pawn]

what no, this advice is for AddForce specifically

also deltaTime is the same as fixedDeltaTime within FixedUpdate

[wintry quarry]

MovePosition doesn't respect collision and isn't suitable for player movement.

[solar hill]

So whats the better alternative

[naive pawn]

set velocity or add a force

[wintry quarry]

The easiest to work with will be setting the velocity

[solar hill]

Oh i see

Thanks !

Does c# have a dictionary that behaves like the one in c++?

[wintry quarry]

C# has a dictionary yes

Not sure how the C++ one behaves exactly but they're pretty much the same in all languages

[night raptor]

If you have some specific difference in mind, please specify it, not all of us use c++

[naive pawn]

map in c++ is a sorted map/dict, c# has OrderedDictionary iirc

Dictionary in c# is a hashmap/dict/table, what unordered_map is in c++

structures in different languages will be implemented differently and will not act exactly the same

consider what functionality you actually need and go from there, instead of trying to find a direct equivalent from a structure in a different language

[slender nymph]

OrderedDictionary is .net 9+ though so not available in unity

[naive pawn]

very few structures in c# will behave like c++ analogues because c# doesn't have copy constructors 😛

[wintry quarry]

I feel like we're getting ahead of ourselves

The basic contract here is key/value mapping presumably

[eager spindle]

its a little different, in c# you need to initialise the values before being able to use it.
in c#, you must call Add first before being able to use the values

Dictionary<string, int> ages = new Dictionary<string, int>();
ages.Add("Alice", 30);
ages.Add("Bob", 24);

but in c++ you can just use it directly

map<std::string, int> ages;
ages["Alice"] = 30;
ages["Bob"] = 24;

[rough granite]

Ah makes sense

[naive pawn]

(yeah im just trying to say - actually ask that instead of trying to get an equivalent)

[slender nymph]

you can do that in c# too

[wintry quarry]

You mean you need to create the Dictionary, yes.

[naive pawn]

this just.. isn't true?

[wintry quarry]

You can use the [] syntax in C# as well

[eager spindle]

My use case is a bit niche in that I want to

Dictionary<string, Action> actions = new();
actions["money"] += moneyAction;

But calling actions["money"] += moneyAction; calls NRE

[naive pawn]

does it? i would assume it says the entry doesn't exist instead of an NRE

[eager spindle]

Oop yep I meant the entry doesnt exist

[naive pawn]

but yes keying into a dict does not default-create the element like c++ does

[eager spindle]

I was thinking that in c++, it would instead treat actions["money"] as an empty Action that would just allow me to add to it

yea i wanted that default creation method

[naive pawn]

yeah c# just doesn't have that concept in general

[wintry quarry]

I mean, that's a pretty minor difference

[naive pawn]

(not really, it means upsert is given for free in c++)

[eager spindle]

I see, I'll find another way

[wintry quarry]

If statements exist.
TryGetValue exists

The difference here is really in the fact that Action is an object that needs to be created

If it was a struct it would be equally free

[naive pawn]

generally for [non-c++ language] you would check for existance and then choose to add or update, or default-create the entry and update

it's only c++ that has the default-init behavior afaik

[naive pawn]

no? you'd still get an entry doesn't exist error because the issue is with the key, not the value

[wintry quarry]

Yes if you blindly try to access it instead of using TryGetValue

[soft lotus]

Im working on implement a save file system to my game, and i want each save file to be accompanied with a little screenshot of the game, for better readability. How can i take a screenshot & save it to file? Additionaly, i'd love for the screenshot to be in a different aspect ratio from the game itself (4:3, instead of the game's 16:9)

the save files themselves are .json

[wintry quarry]

Render a camera to a RenderTexture. Googling it should give examples

[naive pawn]

...which is the exact situation we're talking about? value and ref types just don't make a difference here at all, no? you can still do += on a null delegate

[soft lotus]

i've used render textures before, but how would i save it to file?

[naive pawn]

what's the current issue?

[restive sigil]

not changed.

i gave up and put it in a messy update loop

[naive pawn]

so it's not ending the loop, it's just... not continuing

which kinda sounds like it not being passed to StartCoroutine, but it is...

[restive sigil]

this

so yield just stops all coroutines smh

funnily i have a GIF script using ienums and they somehow work

[naive pawn]

well yes, but it's supposed to continue in the next frame in the case of yield return null

[restive sigil]

i made that before this tho

[rich adder]

yield wait not stop, otherwise it would break

[restive sigil]

and it loops if yields are removed from animroot

but it currently works with the update function either way

[hot wadi]

Should I use a Pool to reuse my bullets or should I just instantiate them when needed?

[rich adder]

always good idea to use pooling for bullets , they are always instantiated and destroyed and can save you lots of GC operations

[craggy depot]

Hey yall, so I’m new to unity, and am making a project for digital twins, I wanted to ask are there any good tutorials or materials I can refer to? I do use chatGPT, but after a point I’m not able to make it work

[waxen glacier]

How can I get the value of the angle between a Raycast and the normal of whatever it hits ?

[waxen glacier]

Unity documentation is pretty useful, they also have a bunch of tutorials on their site, as for videos you oculd check out Brackeys, he's pretty good

[craggy depot]

Oh cool thanks

[rich adder]

some like this maybe ?

var incomingDir = ray.direction;
var hitNormal = hit.normal;
float angle = Vector3.Angle(incomingDir, hitNormal);```

[waxen glacier]

thanks i'll try that, just gota figure some stuff out beforehand

[rich adder]

ok. depends also what u want to do there might be a few more alts

[waxen glacier]

Yeah just gotta get the angle that's all, so I can check for slopes since I want to add sliding

[waxen glacier]

Works well, thanks a lot

I just had to quickly research how raycasts work cuz I couldnt get the "hit" variable to work

Ya learn somehting every day

[scarlet skiff]

whats the easier simplest way of making an on value changed for a bool? and getting the old value and the new value

[waxen glacier]

Another question, the blue box is the Ground Check, and I set it to turn off the gravity on the rigidbody if it's grounded, only problem is, when I jump on the cube's edge for example, the rigidbody still kinda bumps off and slides down. I want it to stay at the exact same height it's at when the gorund check first collides with the cube, I tried manually setting the downward velocity to zero if it's grounded and it didnt work, any ideas ?

[naive pawn]

probably with properties

no reason to provide the old value for a bool though lol

[naive pawn]

did you like, also remove gravity? also you have an error in console, that may be related

[waxen glacier]

That error has nothing to do with it dw, and yes I do turn off gravity as soon as the capsule is grounded but in this case it still slides down a bit before settling like in the image i sent

[naive pawn]

yeah that would be due to the existing velocity

perhaps show !code

[naive pawn]

why are you resetting the angular y velocity

that's how fast you're yawing

motion is linear velocity

[waxen glacier]

oh bruh, that was a typo, lemme change it to linear and see if it works

changed it but the problem persists

if i jump further on the cube and walk backwards until the Ground Check barely makes contact there's no problem, the capsule only slides down If jump on the cube's edge directly

let me take a screenshot to make it clearer

[naive pawn]

-# a literal edge case

[crystal rain]

how do you make your text small or big

[waxen glacier]

we love some edging

[naive pawn]

you mean in discord or in unity lol

[crystal rain]

Discord 🤣

[waxen glacier]

As you can see the capsule still says at the same height if I jump correctly on the cube then slowly walk backwards, but if I jumped now from the position shown in the images, the capsule just bumps off the edge of the cube and falls , that's what I want to remove

[crystal rain]

Forgot to specify

[naive pawn]

it's extended markdown

# h1
## h2
### h3
normal
-# small
```the small version is a discord specific thing, and generic markdown goes to h6

you can google all this though

[naive pawn]

not sure what i'm looking at in either of these images tbh
which one is the scenario with the issue, and what exactly is the issue? (i'm not seeing it)

[crystal rain]

Try turning off gravity lol

[waxen glacier]

Already did that

[crystal rain]

Oh

Hahaha

[waxen glacier]

the issue is this image, I basically want the bottom of the capsule to stay on the same height as the surface of the cube, when I jump on the edege of the cube, despite it making contact with the Ground Check, the capsule still slides down or even bumps off of it even though gravity is turned off

[crystal rain]

Are the objects frictionless

the player and block

[waxen glacier]

the capsule is frictionless, I removed the frictionless component from it and it seemed to kinda reduce the problem, the capsule wasn't bumping off the cube as hard

[naive pawn]

have you tried debugging and going frame-by-frame to see if the ground check and velocity reset are perhaps happening after it slides down or something like that?

[naive pawn]

i don't think friction would matter too much here, what about bounce

[crystal rain]

Can you turn off ground check? (I don’t use unity often I have only opened it once and understood nothing and was overwhelmed)

[waxen glacier]

Why would I turn off the gorund check ?

[waxen glacier]

I'll try recording it and sending it here

[crystal rain]

Maybe it is pulling it to the ground because it thinks it is hovering over the ground

And doesn’t like it and jerks it to the ground

[waxen glacier]

Managed to record it

Look at when i'm already standing on the edge of the cube and try to jump

[naive pawn]

you should probably stop suggesting random stuff if you don't understand anything about it lol

[crystal rain]

Uh it was worth a try

[naive pawn]

snapping happens with depenetration

[waxen glacier]

what's depenetration ?

[crystal rain]

When you slide off the edge is when you try to jump

[naive pawn]

this moment, right? where it's falling and the ground check kinda falls through the block a bit before the gravity disable kicks in

[waxen glacier]

Yup how can I prevent that from happening ?

[naive pawn]

i'd guess that's just gravity being faster than the physics tick rate, rather than any issue with your code

you could make it snap up to the surface, but that might be jarring

or i guess gradually move back up to the surface

but if you want that behavior, why not just use a boxcollider

[crystal rain]

Couldn’t you also just make a hit box for the player

[naive pawn]

there's already a hitbox, it's the green wireframe

[crystal rain]

Try making the hit box bigger than the little oval

[waxen glacier]

bruh thanks, box collider fixed it, ig it's my bad for making a cubic ground check for a capsule collider

[naive pawn]

if it's still a capsule collider it wouldn't really change the behavior

it'd just make the effect less

i get that you're trying to help, but if you have no idea how anything works, you just aren't really going to be able to help

[naive pawn]

if the normal boxcollider collision works for you, you should be able to remove the antigravity/velocity reset stuff too

[crystal rain]

Idk I was just thinking that like Minecraft has a bigger hit box than the actual player model and it stays on platforms

[naive pawn]

no, it doesn't

[crystal rain]

Huh

[naive pawn]

just, in case that ends up having accidental effects on stairs or moving platforms or something lol

[naive pawn]

the minecraft player's hitbox is a cuboid shape, that's why it doesn't slide. and minecraft doesn't have slopes.
the model protrudes out of the hitbox in some areas.

[crystal rain]

He doesn’t have slopes so I thought it would help I was not thinking in future

[naive pawn]

there's a slope check in the code

[crystal rain]

Oh i didn’t see that

[naive pawn]

nothing personal against you, but really - if you don't have the background knowledge to actually understand what's going on, your suggestions are just unnecessary noise

[crystal rain]

That was very personal against me

[red igloo]

I have this issue where when the player "dies" and its trying to teleport the player to the spawn point this happens (watch the video)
Script : https://paste.ofcode.org/cXXV74g3pbWsB5kFhQDP6x

[crystal rain]

If you have to say that then it is going to be personal

[rich ice]

the point they're trying to make is still true. you haven't shown any signs of having knowledge related to unity, just general game dev. if you want to actually help here than understanding the engine is an entry level requirement

[crystal rain]

I don’t know where to start learning

[waxen glacier]

Ok so it removed the issue of the ground check slightly sinking into the cube, but the bounce is still there that's what bother me. Imagine jumping right on the edge of a crate in CSGO, and then jumping again while on it without moving a single step only to get knocked off of it the moment you land

[rich ice]

[crystal rain]

That hasn’t helped me at all

[naive pawn]

it applies to any beginner trying to help even though they don't have the knowledge to actually present useful suggestions

[naive pawn]

right, so that would be the depenetration thing probably

[waxen glacier]

Mind re-explaining what that is ?

[crystal rain]

I can still present ideas that may end up being helpful

[waxen glacier]

is it basically the engine's physics acting before my code can disable gravity ?

[naive pawn]

you can, but are you? most of them won't be, as demonstrated in your attempt

[naive pawn]

so basically how physics works is it's gonna step work out where stuff will be after velocity has been applied, then figure out what stuff is inside each other, and then try to make them not be inside each other

so gravity might make the player and the box intersect like this for a brief moment, then physics will figure out - hey, those 2 things collide, they shouldn't be in each other, and then it'll push the player out of the box (or vice versa, dependant on dynamic vs static and mass and stuff)

i guess what is happening here, is that due to the player being on the edge, it ends up looking like this - the physics system looks at this and thinks the easiest way to depenetrate is to make the player move out instead of up, which is technically correct, just not what you want

[waxen glacier]

Ah i see, is there a workaround for that or is my only solution switching from a rigidbody to a character controller ?

[naive pawn]

(or the physics system just pushes them directly apart and that ends up being out. idk the specifics)

[naive pawn]

well a CC would most likely give you more control over this, but im not sure if you can solve it with physics, it might be possible

[waxen glacier]

Alright then, thank you so much man, I might have to switch to a CC then, it's annoying cuz i'll have to implement stuff like gravity myself but i guess it's worth giving it a shot, I appreciate the visual explanation

i'll just duplicate my movement script and make the copy work as a CC so I can still go back to rigidbody if i mess anything up

[naive pawn]

seems like this is... not a particularly easy problem to solve with physics

imo this isn't too egregious and would be a lot of effort to switch to CC just for this change, but power to you if you decide to fix this

an alternative would be to i guess extend the ground check to snap to the ground better, but that might also be a lot of effort for not much gain

[waxen glacier]

You're right, especially since I at least fixed part of the problem, i think what i'll so is play some games where I can recreate this scenario and see if they have the same problem or if it even feels that weird in an actual game, then i'll decide if it's worth fixinf

[naive pawn]

there's this thread about physics if you're curious, though since it's about systems in general it might not be super applicable to your situation
https://discussions.unity.com/t/depenetrate-in-one-direction/892023/4

[waxen glacier]

thanks and btw, i'm actually stupid, I extended the Y range of the ground check by 0.02 and it totally fixed the problem

[naive pawn]

with the antigravity/velocity reset?

[naive pawn]

well keep in mind that could have some unintended effects if you aren't mindful of it lol

[waxen glacier]

Yeah thanks, i did some more testing and the problem wasnt actually fully solved, i guess i'll just do what I said earlier, either way I atleast know why its even happening so I can stop loosing my mind over it, thanks a lot for helping :D

[crystal rain]

Can you stop hating

[naive pawn]

buddy you are creating unnecessary noise that isn't helping

[crystal rain]

Ok and

[waxen glacier]

Bro I get you were trying to help but it's better for you to just admit you're in the wrong here, you were drowning out actual helpful messages with your ideas

[naive pawn]

(which could probably be solved by reducing the x/z size of the ground check, but that probably just goes full circle to the box thing not being consistent lol)

[naive pawn]

spamming is against #📖┃code-of-conduct

[crystal rain]

It is not spamming

It is trying to help

[waxen glacier]

yeah i'll just play some games with crates in them and see if this problem occurs in them too

[naive pawn]

not much of a difference when you just are not able to

[wintry quarry]

There's a function to encode a texture as a PNG

[waxen glacier]

You weren't really helpful tbh, throwing out random ideas doesn't really do much, @naive pawn could actually tell me what the problem is because he has enough knowledge on the matter, instead of arguing here you could've just followed along and learned something yourself

[crystal rain]

I have

[naive pawn]

oh actually just realized, this doesn't happen with unity i don't think? at least with the 3d physics engine
there's a depenetration velocity, whereas source iirc does snapping - it tries to find an open space and teleports you there

physics2d doesn't have "depenetration velocity" so it might be snapping

[soft lotus]

I think i found it, let me try
