[cosmic rain]

"yeah" doesn't exactly answer my question...

[daring hull]

no that was the problem

youre right

that was the default size for the collider i didnt notice that

i fixed it and now it works

somethings wrong with the actual rules but i can figure that out myself probably

i was stuck on that for like half an hour

[outer otter]

this is a pretty general question but what is the next most important thing to work on for a game after movement? im thinking an inventory system, or a health system, but im running in circles like does the chicken come before the egg

ive gone a bit into the inventory side, im able to pickup items, and display it in my inventory, with the corresponding data saved with it. but i dont understand it fully.

[west sparrow]

That depends a lot on the game

Probably health and lives

I like to get stats out if the way early on, and the UI.

[outer otter]

im taking it super slow, i made a few games so far all the way through with simple mechanics, but now im making a more robust fps with health and food. kind of like how Green Hell does there system

[west sparrow]

First step is the paper prototype though. Get the blibs working and make sure it's fun first

[outer otter]

yea i got a fps movement system I can use for the rest of my projects now, its really nice

[west sparrow]

I'm not sure what that is. But I'm definitely a check off the core first kind of person

[frosty siren]

fps = first person shooter in this case

[west sparrow]

No, green hell

[frosty siren]

it's a survival game where you play in the jungle so it has well fleshed out survival mechanics such as health and food

[outer otter]

yea super fun game you need to play

im afraid of going through with this tutorial bc if i implement it and something breaks halfway thru id be too confused to fix it

[frosty siren]

that's why this server exists ^~^

[outer otter]

yea i guess loll

how can i make a player only jump once when the spacebar is held?

i should push this to beginner

[lean sail]

A lot of tutorials are pretty specific and cant really be extended on much. So its better if you can plan out what you wanna do before following it, so you know which parts need to change

[outer otter]

its hard to know what you need, i overthink it

[cosmic rain]

Don't you have some main idea behind the game, a pivotal mechanic or something?

[orchid abyss]

why

[mossy snow]

you have 3 bugs in there, two of which are helpfully underlined for you to mouse over

[orchid abyss]

[fervent furnace]

not code general

[mossy snow]

3 bugs down, 1 new bug added

[frosty siren]

local variable pain

[orchid abyss]

now

[mossy snow]

nice. Now only code smells remain

[mild coyote]

reading it with 5 little monkey jumping by the bed song in mind

[hexed pecan]

I dont think the cast (ParticleSystem) is necessary

[orchid abyss]

huh

[hexed pecan]

Hmm you are instantiating the blood itself?

Better use a prefab reference instead, I think

[mossy snow]

weird design choices

• the casting as mentioned; it looks like it's already a ParticleSystem, but if it's not you should change the field to ParticleSystem
• reusing your serialized field as a runtime field is smelly. I'd have your prefab be separate (bloodPrefab) while _blood is a runtime value
• you might want to use a pool because currently if you spawnblood and there's already blood playing, the first one will disappear

[mild coyote]

while it might be smelly, I dont think reusing prefab variable will do anyharm
I sometime do that when I just to lazy to write new variable

[mossy snow]

it doesn't technically do any harm which is why it isn't a bug, but it takes 3 seconds to do it right. If you're lazy about something like that, you're probably being lazy on other design decisions too and you'll be punished eventually

[mild coyote]

on a second thought, it wont do any harm only if he properly initiate the instantiated prefab.
also if the particle is set to destroy on stop, it will have null reference error

[mossy snow]

hence, very smelly code

[lean sail]

Just in general it's not a good idea to reuse the variable. Itll be a pain to debug if you ever instantiate a prefab (or so you thought) but it's a game object which has changed in some way

[mild coyote]

If you're lazy about something like that, you're probably being lazy on other design decisions too and you'll be punished eventually
Well, my motto is : "If it works, it works"
I dont really care on how it's written or what design pattern it use XD

if it has no ||game breaking|| bugs, and it runs butter smooth, then it's good enough for me 😅

[mossy snow]

that works in the short term, but as technical debt accumulates it gets harder and harder to add new features. On some future day, you'll solve some esoteric bug due to badly written code by some moron engineer, and when you git blame you'll find out that moron was you 6 months in the past

[mild coyote]

well, let's hope that the game is shipped before 6 months then

[frigid glen]

How do I convert viewport position of a portion of my screen to a viewport position of my whole screen without actually changing the position of that point on the whole screen?

[mild coyote]

something like remap function?
https://rosettacode.org/wiki/Map_range

[frigid glen]

think so

[hexed pecan]

So your camera's viewport rect does not cover the whole screen?

[frigid glen]

Its a camera rendering to a render texture, and that render texture doesn't cover the entire screen. So yes

[hexed pecan]

I feel like camera.pixelRect or camera.rect can help when remapping it

Though not sure if it is relevant if you use a rendertexture. Do you display it with a RawImage?

[frigid glen]

displaying it on a UI toolkit visual element.

I ahve the position I want, just want to be able to display it on my cursor

context is:

I have snapping functionality that I get a world space position on based on the mouse position through the render texture

now I want to convert that world space position to the position of the entire screen so I can display an icon on my cursor and then have it be able to snap onto my that position I want on my render texture. I've gotten as far as to getting the position on that visual element, but of course it isn't the entire screen.

[modest brook]

can anyone help me animate my UI, i have animations but it wont recognize it my code is this:
`using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;

public class HoverOver : MonoBehaviour , IPointerEnterHandler,IPointerExitHandler
{
public GameObject HoverPanel;

public Animator animator;


void Update ()
{
   
}

public void OnPointerEnter(PointerEventData eventData)
{

  animator = GetComponent<Animator>();
    animator.SetTrigger("ScaleWhenHover");

}

public void OnPointerExit(PointerEventData eventData)
{
   
}

}`

[frigid glen]

animator is cancer for UI

just change the postions through code

its called tweening

[modest brook]

how can i do it?

[frigid glen]

get rect transform of UI

[modest brook]

because i managed to the other day but the transition wasn't clean

[frigid glen]

change anchored position

define clean?

like it doesn't ease?

make an easing function

[modest brook]

yeah

[frigid glen]

idk use lerp or something

[modest brook]

i'll look at tutorials cuz i have no idea what that is and so many people keep telling me to

[hexed pecan]

Do you have a camera rendering to the whole screen?

[frigid glen]

yup

[modest brook]

holy shit just looked at a tutorail its solvinmg all of my problems

[hexed pecan]

If you already have a world space coordinate, you can just use camera.WorldToScreenPoint/WorldToViewportPoint on that main camera

[frigid glen]

been there, done that. When doing that, and set position of the circle, it ends up on the middle of my screen. Even though its supposed to be in the middle of the render texture

[mild coyote]

maybe you can do something like this using the remap function from above

cursor.x = remap(vpTopLeft.x, vpBottomRight.x, 0, 1);
cursor.y = remap(vpTopLeft.y, vpBottomRight.y, 0, 1);

[modest brook]

guys really quick is there a way to mention scale in coding?

like instead of transform.position

transform.scale instead?

[mild coyote]

transform.localscale?
if you've set up intellisense properly, a suggestion should popup when you tipe 'transform.scale'

[modest brook]

i think ik what u mean by intellisense but it doesn't work for me

how do i set it up?

i see it in other tutorails

wait ok

guys can someone help really quick

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

public class LerpScaling : MonoBehaviour
{

private Vector3 endScale = new Vector3(0.9437993, 0.9437993, 0.9437993);
private Vector3 startScale;
private float desiredDuration = 2f;
private float elapsedTime;


// Start is called before the first frame update
void Start()
{
    startScale = transform.localscale;
}

// Update is called once per frame
void Update()
{
    elapsedTime += Time.deltaTime;
    float percentageComplete = elapsedTIme / desiredDuration;

    transform.localscale = Vector3.Lerp(startScale, endScale, percentageComplete);
}

}
`

[orchid abyss]

how to add offset so the blood spawns at the center of the prefab enemy?

[frigid glen]

how would I go about getting the corners of a visual element? nvm I think I got it

[modest brook]

i did it i think but i have to go now if i DM u can i message u later?

[thin aurora]

Get the component of whatever renders your actor, get the bounds, half that and use the height for the offset

Or this, maybe https://docs.unity3d.com/ScriptReference/Renderer-bounds.html

Can also use the collider bounds

[mellow sigil]

No, post again here and whoever is available can help

[thin aurora]

https://docs.unity3d.com/ScriptReference/CapsuleCollider-height.html

[modest brook]

fair enough

[mellow sigil]

actually post to #💻┃code-beginner instead

[modest brook]

okok

[frigid glen]

Ok so I tried it and it aint working, probably implemented remapping wrong. I asked chatgpt to do some viewport remapping and it always yeilds what happens

[frigid glen]

here ^

Like I'm tryna stop this

Vector2 snapPos = Collider2DHelper.FindClosestPointOnBody(_currentRay.Value.rigidbody, _mousePosition);
Vector2 snapScreenPos = _creationCamera.WorldToScreenPoint(snapPos);
_displayTexture.rectTransform.anchoredPosition = snapScreenPos;

[mild coyote]

🤔 if you want to remap from fullscreen position to viewport position, try reversing the remap

cursor.y = remap(0, 1, vpTopLeft.y, vpBottomRight.y);```

also, if you are using screen position instead of viewport, change from 0 and 1 to 0 and screen.width(or height for y)

here's a remap function I got from google
well, it's actually mgear's XD

[nimble cairn]

Will OnTriggerEnter still run physics checks even if there is not a trigger component on the gameobject?

[tawdry jasper]

I have an axe item that can lodge into targets. There are colliders and a rigidbody. The item also has a trigger collider that's used to determine if you're close enough to pick it up. I had the item go crazy if the target was also a simulated rb (like a hanging target on some joints), what solves this was rb.detectCollisions = false as soon as the axe is lodged in a target. BUT this stops the ontriggerenter working and the axe can't be picked back up.

[cosmic rain]

It won't be called.

[nimble cairn]

Thanks, I was worried that it was hogging up resources.

[tawdry jasper]

I'm trying to have the item have a disablable collisions on it's rb and still keep my triggers for the item pickup, and found advice to make the pickup trigger a child of the item. but now I'm getting this error: MissingReferenceException: The object of type 'Transform' has been destroyed but you are still trying to access it. Your script should either check if it is null or you should not destroy the object. no objects are getting destroyed. only re-parented. Is it possible unity recreates the Transform's when the hierarchy is modified?

[cosmic rain]

Are you accessing the parent perhaps?

[tawdry jasper]

yes, whenever the player enters the pickup trigger I'm adding the triggers transform.parent.parent to a list of potentially picked up items (and removing on trigger exit). then when the player hits the pick up button an item is grabbed from that list

[lean sail]

This seems... fragile. You should ideally only be interacting with the thing you interacted with via physics and that is usually a parent object. Excluding cases of having a GO acting as a wrapper object.

Regardless you need to show code for help with the errors specifically. Or just follow what the error says about it being null

[tawdry jasper]

I think I was mistaken and having the trigger as a child has the same issue, as soon as I disable collisions on the item rigidbody, the trigger colliders stop working.

(I read somewhere that the trigger colliders are unrelated to the physics collisions and this approach should work )

[lean sail]

Well ya if you disable a collider, you arent gonna get a physics message for it..

[tawdry jasper]

not disabling the collider. calling rigidBody.detectCollissions = false

This seems to affect any trigger colliders under that rigidbody in the hierarchy.

[old nymph]

Hi guys, have a nice day.

I'd like to ask how to maintain UI position after changing its parent. Known that the UI is heavily nested in the first parent game object and the second parent is more simple.

I have tried using belows but no use.

SetParent(parent, true/false);
---
var pos = transform.position;
SetParent();
transform.position = pos;
---
transform.TransformPoint();
---
OnTransformParentChanged()...

The drag in the inspector works just fine but I have no idea how its code work.

[deft timber]

UI works on anchoredPosition

[old nymph]

What do you mean?

[deft timber]

rect transforms, works on anchoredPosition

and you should modify that instead

• anchoredPosition

• position

[old nymph]

The UI I mentioned is heavily nested. AnchoredPosition looks like a local position for UI element to me and yes, I have tried that solution too but no use.

[deft timber]

there is no local/world position for the UI elements

it's jsut anchoredPosition

[old nymph]

RectTransform is just a derived class from Transform and It does have world position and local position, I believe. But I'm looking for the code/mechanic of the drag to change the parent of a gameobject in the inspector.

[tawdry jasper]

have you seen this? https://docs.unity3d.com/ScriptReference/RectTransformUtility.ScreenPointToLocalPointInRectangle.html

you could try grabbing your current transform.location, use Camera.main.WorldToScreenPoint(worldPosition) to get screen coords, and then try the above to calculate your local position with respect to your new parent's rect?

[narrow summit]

anybody has a handy json convertor which works for AnimationCurves?

[latent latch]

that actually sounds like quite a bit of data to serialize with json (guess it depends how much you are evaluating throughout the curve)

what's wrong with grabbing the animations keys and storing those

[late lion]

If it's serializable in Unity, it should be serializable with JsonUtility.

[latent latch]

Ah, right they should be serializable. I'm thinking animation clips themselves, but AnimationCurves are very much just a collections of keys.

[thin aurora]

Yuck, please don't use JsonUtility

Even if it works

[thin aurora]

Serializing it is actually pretty easy. https://docs.unity3d.com/ScriptReference/AnimationCurve.html
Just take the keys and the wrap mode and you can use these to recreate it

Serializers like Newtonsoft allow for custom serialization based on type so you can make this an automated system on serialization, to avoid mistakes

the player lives even when the health is 0 if enemy hits player once more when health is 0 then it dies.

how do i make the player die when it hits 0

[vapid condor]

if (playerHealth <= 0)
  Die();

[mellow forge]

i used the die function as an event in the death animation so after it finishes the death animation with deathanimplay it calls die through event

the player dosent die when health is 0 if the player gets hit once more then it dies

so to die the player has to get attacked once more even if its 0

[vapid condor]

you should do it the other way around, call the die function in script, and play the death animation in the die function and use the animation events to reset or something

[mellow forge]

i see ok

[vapid condor]

wait so you want for the player to die only when health reaches less then 0? not equal to 0

[mellow forge]

i want player to die when health reaches 0

[sudden relic]

I wonder if it has to do with your state transitions.

[mellow forge]

its not that the animation dosent play player can do all the stuff even when health is 0 like attacking killing collecting jumping

yes i can log a message

lemme try

[sudden relic]

I know, but I'm having issues rotating it.

i tried something else i changed the death deadline to 10 and it worked

but when its 0 you have to be hit twice

How can I make it write to the console as long as I hold down the button? Normally, when we use a button, it gets triggered when we release it instead of holding it down. However, I don't know how we can determine what happens while the button is being held down.

what's the code you're using at the moment?

[swift falcon]

I want the gun to fire as long as the button is pressed in the mobile game. I wrote the ignition code, but I couldn't do it because it didn't trigger as the button was kept pressed.

[swift falcon]

ui

AttackButton.onClick.AddListener(Attack);

[soft shard]

I find this project very nice for visualizing the casts: https://github.com/vertxxyz/Vertx.Debugging

Theres a little bit of setup, but you basically add OpenUPM, then you can install the git project from Package Manager and use it just like Physics.XCast (same params) just replace it with the namespace this package uses, it will also show when there is a detection

Is now a good time for me to put in stuff about my problem?\

Don't want to cover up other peoples' inqueries

Good enough of time as any other I guess:

I've been trying to set up some movement code to get myself back into the swing of things in Unity. The issue is that 1 in every 10 or so jumps is unusually higher than the others. It also seems to differ in the build? The big jumps seem to be default in the editor, but the neutered jumps seem to be the default in the build.
https://paste.ofcode.org/VRLrXyamAXvA6Rew6VpukK
I think the offender might have something to do with the implemented dynamic jump features.
I read online that it has something to do with putting that stuff in Update() but that doesnt seem to apply here. So, idk whats going on.

Then you have missed a step somewhere

[static matrix]

eh there is a thing with some jump codes where if you hit the button twice quickly you can trigger a jump again

but idk if that is your problem

[bright maple]

There's a jump cooldown to help deal with that. Also the jump force is set, not added. So, I'm not sure that could cause it.

[static matrix]

well even if it is set it resets the amount it had slowed down

could also be you are triggering the jump at the right time to do it before you are fully on the ground

try shrinking your jump detect box, see if it fixes it

[bright maple]

The size of the groundCheck is considerably smaller than the jump size difference. I've tried it though, it doesn't work. Also, it just causes other problems with movement.

[jade latch]

i have a board game where the board is randomly generated and then copied, mirrored and flipped to so both sides are equal but now when im adding pieces and coding where they are able to go i run into an issue since im using a 2d array to keep track of the placed its able to move to but the cordinate values doesnt go from 10x10 to 0x0 but instead from 10x5 to 0x-5 and giving the array a negative value ofc gives an error. any ideas how i could bypass that? ive tried to offset it but it just moves the issue.

[static matrix]

not totally sure what you are asking but I did write some (albiet java) code for mirroring an image

    var Pixels = pict.getPixels2D();
    var len = pict.getWidth();
    var Y = 0;
   
    for (Pixel[] pixels2 : Pixels) {
      var Iter = 0;
      var HoppedIter = 0;
      
      for (Pixel pixel : pixels2) {
        
        
        if(Iter > len/2){
        
          pixel.setColor(pict.getPixel(len-Iter, Y).getColor());
          
        }
        
        Iter += 1;
      }
      Y += 1;
    }
    pict.show();

  }

this was that put it should be relatively translatable

[bright maple]

I should make note that this problem only seems to be an issue in the builds. The big jumps are consistent in the editor. Which makes me think its an Update()/FixedUpdate() problem.

[jade latch]

im asking how i can work around the fact that arrays only go in positive values and one of my values can be negative

if thats a respond to me

[static matrix]

it is

tbh the solution is to not use negative values in a place like this

or something with mathf.abs

[leaden ice]

You can't have negative indices in arrays. Just provide some kind of offset so you can do:

int myCoord = -5;
int offset = myArray.Length / 2;
myArray[myCoord + offset];```

[static matrix]

yeah or that

[bright maple]

I was just thinking this. Offset the indices by half of the size of the array

[leaden ice]

basically let's say the array has 10 elements. You want to consider [-4, 5] instead of [0-9], To achieve that you have to add 4 to the index before using it.

so yes, adding half the size of the array.

[jade latch]

i tried that but it pushed the issue just further down but i can implement it and work from there

[leaden ice]

I mean it's an entirely tractable problem, you just have to give it a little thought

[bright maple]

It's a workaround I guess
Also, hi Praetor. Glad to see you're still dishing out helpful coding advice to people

[leaden ice]

The other option is to use a Dictionary instead of an Array

especially if this is a 2D grid, very easy to make a Dictionary<Vector2Int, Piece> or whatever

[jade latch]

im quite new to c# so not too sure what that is

[leaden ice]

You should go look it up. It's extremely useful and common

[jade latch]

i will thanks

[leaden ice]

every programming language has an associative array of some kind. They're called Dictionaries in C#, Maps in Java, HashTables in a lot of places.

[jade latch]

ahh maps im slightly familiar with from js

[leaden ice]

it's the same thing

in fact every JS object is essentially a Dictionary<string, object>

[jade latch]

but still very little clue on how they work tbh

[frosty siren]

meanwhile, html:

[jade latch]

so in that example just have the coordinates as the first values then true/false as the last one for example

[leaden ice]

not sure what you mean by first and last values

I don't really know how your game works. Let me use chess an example. In Chess you might have a Dictionary<Vector2Int, Piece>. The Vector2Int is the coordinates. The Piece can be any chess piece, e.g. Knight, Rook, Bishop and its color for example

[static matrix]

or null in the chess case

[leaden ice]

I mean you could have it be null or you could just not have that coordinate in the dictionary, which would be cleaner

[naive swallow]

HTML isn't a programming language

[frosty siren]

touche

[jade latch]

fair enough, what i want with that code is to display every place that piece can go to (any spot within a range)

[static matrix]

well I presume that spaces that don't have a piece on them would just have the piece be null instead of removed from the dict

[leaden ice]

It would be cleaner to just remove it.

that would be weird to use null

because then you'd have some entires that are null and some that don't exist

and both of those things would mean no piece is there

[jade latch]

its not to track where each piece is but rather where they can go

[leaden ice]

and if you are going to go throught the trouble of populating all the spaces with null you might as well just use a 2D array

[static matrix]

oh yeah I guess heh

[leaden ice]

If you just want a set of legal places for the piece to go just use a HashSet<Vector2Int>

if the space is in the set, it's legal, otherwise it's not legal

[latent latch]

infinite grids usually are dictionaries, but if you got like a chess size board I'd just make the 2D array

[jade latch]

i got a 10x10 grid but since its a copy paste the board cordinates goes from 10x5 to 0x-5 instead of 10x10 to 0x0

[leaden ice]

well yes chess is typically an array but chess was an example for illustration, they're not making chess

[mystic pollen]

is this the place i can get help with code

[jade latch]

its an very advanced version of chess tbf

[leaden ice]

Just do something like this:

public struct Coordinate {
  public const int boardSize = 10;
  public const int halfSize = boardSize / 2;
 
  public int x;
  public int y;

  public Vector2Int ArrayCoords => new Vector2Int(x - halfSize, y - halfSize);
}```

then you can use your Coordinate struct however you want in your code, and when you want to access the array you use the ArrayCoords property.

[latent latch]

chess 2.0

[jade latch]

thanks ill see if i can figgure it out

[jade latch]

machine strike from horizon forbidden west to be exact

[leaden ice]

tbh I don't really see why you need the negative coordinates.

In all your code you should deal with positive coords

if you want to display them on the map as negative, that's just a display thing

[jade latch]

i wish so too

[leaden ice]

that happens at the very end when displaying to the user

it shouldn't be part of your code logic

it's like in chess the coordinates are a1, b7, etc..

internally in any chess engine it's just two numbers, both zero indexed

the letters and the 1-indexed number are a last second display translation for the User's benefit

in fact in many chess engines it's just a single number 0-63 to indicate the board space. The internal representation doesn't have to match what the player sees.

[jade latch]

ill have to look at the code i made to define the cordinates to see if i can adjust that

[spring creek]

Yes
Oh, I see you asked about networking in the other server though. So #archived-networking would be better if it's the same question

[jade latch]

that worked, why did i not think of that before

[royal wigeon]

I'm trying to get some realistic camera bobbing, but I don't just want some sine waves going up and down, I can't figure out how I would do this since I'm not that good at math, and there are no videos of realistic camera bobbing online, anyone willing to help?

[latent latch]

use an animation curve

[royal wigeon]

I have no idea what that is yet, I haven't dived much into animations.

[main coral]

Hello I have a problem on my TMP_Dropdown! When I have my dropdown menu 8 has the value of 0 and zero the value of 8! whats the problem here ?

[simple egret]

Well it's clear here that the option "number 8" is at the first position in the options list, so it has index 0 in said list

And the last one, the "number 1" is at index 7

[main coral]

Where is my mistake ? In the dropdown component ?

[simple egret]

No, probably in the code that handles it

[main coral]

if I use OPTION = 8 i want that it has the value of 8 in the code

public TMP_Dropdown MyPlayerCountDropDown
{
get { return m_PlayerCountDropDown; }
}

m_uILobbies.MyPlayerCountDropDown.value

[simple egret]

Yeah the On Value Changed event will pass the index, not the option text to your function

[main coral]

but when I change the dropdown menu in the inspector when I pick 6 it has the value of 2 (look on the pictures above)

[simple egret]

Yes that's normal!

Because the option with the text "6" is third in the list, so at index 2

[main coral]

ok i got it

what is the best to get the int from the dropdown ?

I use it to create a lobby and I want use it for 1-8 players

Lobby lobby = await Lobbies.Instance.CreateLobbyAsync("My Lobby", m_uILobbies.MyPlayerCountDropDown.value, lobbyOptions);

[simple egret]

That would be the text of the selected option, and you will get it as a string.

[main coral]

how do I get the text of the selected field ?

[simple egret]

dropdown.options[dropdown.value].text

If I remember correctly

[main coral]

is there a way to get it as int ?

[simple egret]

Not directly, you need to convert it, like with int.Parse()

[main coral]

thanks a lot

[vagrant blade]

@zealous crane don't crosspost

[zealous crane]

okey

[main coral]

this did work for me:
int selectedValue = int.Parse(m_uILobbies.MyPlayerCountDropDown.options[m_uILobbies.MyPlayerCountDropDown.value].text);

ok

[lavish frigate]

Im trying to make an enemy that travels around terrain. Like the little bugs from hollow knight. Any way i can simply make an enemy crawl around a collider?

currently doing this, which makes it freak out at a turn because rotating it does not imply correct position after turning. So the collision checks fail when rotated once

[swift falcon]

I got a navmesh surface and agents and they chase the player but it doesn't jump at all and if it cant reach the player it just stops. How can I fix this?

[charred ruin]

I'd recommend using Unity's pathfinding. Coding that on your own will require a lot of work and a lot of code.
https://learn.unity.com/project/beginner-ai-pathfinding

[lavish frigate]

its a 2d platformer game so i dont think thats what i should go for right?

[marble mauve]

anyone know why I am using a singleton and I am settings a TMP Text in a property called text. Then in a funcion called changeText I am changed the text of the TMP text I set in the inspector but it turns me this error Idk why.

[somber nacelle]

what is line 40 or PersistentManager.cs

[marble mauve]

this.Text.text = "test"

[somber nacelle]

then you are likely calling that method before the Text variable has been assigned or on an instance where it has not been assigned

[marble mauve]

Mmm there is a delay of 2 seconds before calling the function which change the text

One possible reason could be that all the container where the text resides is disabled but I active it before changing the text

[somber nacelle]

that does not mean that either of the things i said is not true. in fact, one of the two things i suggested has to be true

you've shown a single line of code so i can only guess at what it is. consider showing more code

[marble mauve]

Mmm know I can't show more as I send the error and disconnect I have been coding for hours. How I can see if the variable has been assigned?

It could be that the persistent manager is created before the text component was created?

[somber nacelle]

https://unity.huh.how/runtime-exceptions/nullreferenceexception

[mossy snow]

Does your singleton implementation have the ability to create itself if it doesn't exist? I have a feeling you're about to find out why singletons are a controversial design anti-pattern

[frosty sequoia]

hey uhm, why can i see the red gameobject in the scene but not when i look in the game viewer

oh wait, nvm i realized why. it was behind the camera lmao

[tight ice]

https://i.imgur.com/c7qBYwS.gif
why might this code, which spawns a raycast from a gray cube and shoots downward, be failing to instantiate the red cube prefabs on the box below it?
instead, the raycast does not detect the box below it-- only the floor-- so the red cube prefabs get spawned on the floor instead of the box

The box has collider active. (Pic attached of box inspector properties)

[quartz folio]

It just looks like it's probably not over the edge enough

[tight ice]

that.. may actually be it, it looks like if i move Z by 0.01 then it works, okay that revealed another problem lol that i can finally fix thanks!

Localization package ?

[hard viper]

is there an already made string-like class for strings that are multi-language? wouldn’t be too hard to code, but I am wondering if someone already made one

[rigid island]

2 localization questions back to back , nice

[hard viper]

his question reminded me that it was a thing I’ve been meaning to ask for a while

i was thinking something like class InternationalString with public enum Language {…}, public static Language currentLanguage, and public override string ToString() => strings[(int)currentLanguage]; or something

or something like that. but i feel like i’d be reinventing the wheel, when there is definitely a tool out there for this

[quartz folio]

There's an entire localization package

[chilly surge]

I have my own i18n done with code gen for compile time type safety, but I imagine that's not a common requirement for most games.

[hard viper]

yeah… I’m trying to avoid reinventing the wheel as much as possible.

[hard viper]

how would you rate the unity localization package, between [not worth using] and [very worth learning]

[quartz folio]

I have barely touched it

[hard viper]

[deep oyster]

I've downloaded the unity localization package but I'm having trouble getting it to actually use a different language from English.

[rigid island]

I have not gotten around to learning / using it yet.
Wish could be more help on this, Sorry.

[cold parrot]

its serviceable

certainly beats rolling your own. It feels a bit overengineered at first glance, but it actually just gives you all the tools right from the start that you'd need eventually anyway, but just don't know yet. In some simple cases you'd ofc be done quicker with a DIY solution; Those would be ones without a team or any need for mixing editor & code based workflows.

[crisp bronze]

Hi, why does using using this code make my Wirecube disappear in the Scene view?

Gizmos.matrix = transform.localToWorldMatrix;
Gizmos.color = Color.blue;
Gizmos.DrawWireCube(transform.position + Vector3.up, new Vector3(1f,2f,1f));

I'm just trying to make the Wirecube gizmo rotate along with te rotation of the Transform

[quartz folio]

Presumably because you're drawing it at its position but locally to itself, so you've translated it doubly

localToWorldMatrix already includes the position, don't additionally use transform.position to offset it

[crisp bronze]

Ahh, thank you

[hard viper]

also make sure this is in OnGizmosDraw…Selected etc

[old nymph]

Thank you for the suggestion!

[faint hornet]

hey everyone, i am having an issue with a struct that i created and it has an initializing function attatched to it but it is not working.

I have an array of struct that i loop through in the awake function and calling init on every one of them but it is not populating.

here is the struct:

[System.Serializable]
struct RectInstruction
{
  public bool isHorizontal;
  public RectTransform[] upOrRight, downOrLeft;
  public float[] upOrRightDefaults, DownOrLeftDefaults;

  public void Init()
  {
    this.upOrRightDefaults = new float[upOrRight.Length];
    this.DownOrLeftDefaults = new float[downOrLeft.Length];

    for (int i = 0; i < upOrRight.Length; i++)
    {
      upOrRightDefaults[i] = isHorizontal ? upOrRight[i].anchoredPosition.x : upOrRight[i].anchoredPosition.y;
    }
    for (int j = 0; j < downOrLeft.Length; j++)
    {
      DownOrLeftDefaults[j] = isHorizontal ? downOrLeft[j].anchoredPosition.x : downOrLeft[j].anchoredPosition.y;
    }
  }
  public void ChangeAll(float addedValue)
  {
    for (int i = 0; i < upOrRight.Length; i++)
    {
      ChangeRect(upOrRight[i], upOrRightDefaults[i], addedValue, true);
    }
    for (int i = 0; i < downOrLeft.Length; i++)
    {
      ChangeRect(downOrLeft[i], DownOrLeftDefaults[i], addedValue, false);
    }
  }
  private void ChangeRect(RectTransform rect, float defaultValue, float addedValue, bool isDefault)
  {
    Vector2 sizeDelta = rect.sizeDelta;
    float newValue = defaultValue + addedValue * (isDefault ? 1 : -1);

    if (isHorizontal)
    {
      sizeDelta.x = newValue;
    }
    else
    {
      sizeDelta.y = newValue;
    }
    rect.sizeDelta = sizeDelta;
  }

}

The other functions work but not "Init()".
some things to keep in mind;
The rectTransform[]'s are populated in the inspector before runtime with a length on 1 for each.
The float[]'s are not populated in the inspector, I want to automate it using the init function.

[fervent furnace]

Where you call the init

Probably through some indexer?

[faint hornet]

Ive tried awake and start;

private void Start()
  {
    foreach (var item in instruct)
    {
      item.Init();
    }
  }

[fervent furnace]

Item is local copy

It wont affect anything in the collection

[faint hornet]

do i need an OG forLoop?

[fervent furnace]

What is instruct, array or list

[faint hornet]

How do i call init()?

Array

[fervent furnace]

Then use forloop and use indexer call directly

[cosmic rain]

I think you'll be accessing a copy in any case. You'll need to copy the initialized struct back into the array.

[faint hornet]

like

intruct[i].init();

??

[cosmic rain]

I think that's gonna be a copy too.

[faint hornet]

hmm. this is weird i don't understand why

[fervent furnace]

Array indexer not indexer, it actually dereferencing the address

Not returning the copy

[faint hornet]

would a list be different? should i use that?

[fervent furnace]

Indexer of list is returning the copy

[cosmic rain]

Because structs are value types, but Tina is probably correct.

[faint hornet]

so yes? a list does work?

[cosmic rain]

If you want to avoid all that headache, just use a class. I'm sure struct isn't even a justified use case in your situation.

[faint hornet]

will do!

[faint hornet]

wait but can i make an array or classes and have them serializable in in the einspector?

[cosmic rain]

Yes

[faint hornet]

ok ❤️

[fervent furnace]

public class HelloWorld{
    public struct A{
        public int a;
        public void set_a(int num){
            a=num;
        }
    }
    public static void Main(string[] args){
        A[] a0=new A[1];
        a0[0].set_a(10);
        Console.WriteLine(a0[0].a);//10
        List<A> a1=new();
        a1.Add(new A());
        a1[0].set_a(100);
      Console.WriteLine(a1[0].a);//0
    }
}

[swift falcon]

sometimes in my scene, I have to enable and disable a chunk of objects....this results in a lag...to be more clear, in my phone when i enable those objects, for a very small amount of time, the screen freezes...although it isn't much noticeable at first, it becomes clearly noticeable when I am doing it repeatedly...any solution to this??

[lean sail]

What's the use case?

[swift falcon]

@lean sail i turned a huge terrain with trees and other stuffs into a gameobject and then cut into pieces...i have to enable and disable those according to the player's position...

[latent latch]

You can just do the trees yourself and disable them independently, but disabling a whole terrain may have some overhead.

[swift falcon]

i have tried it...i have almost 4000+ objects in that chunk including only the trees and the crates and other stuffs...when i enable and disable those, the screen freezes for a bit...

[lean sail]

Yea not really much to do there if you really need to disable all those objects at once. Maybe split it up even smaller and try to do the work over a few frames instead

[swift falcon]

how do i do that over a few frames?

is there anything like enabling objects asynchronously?

[fervent furnace]

Coroutine

[lean sail]

With a coroutine but try splitting this up into smaller chunks first. I think that would be better

[latent latch]

The terrain itself chunks sections and is overall pretty optimized for not being touched in over a decade. Perhaps just disabling the collider could be a solution and profiling that.

[swift falcon]

how should i do it? using the waitforframes?

[swift falcon]

that terrain is now a gameobject...i am just enabling and disabling those splitted gameobjects having all the trees and other stuffs as its child object

[lean sail]

I dont recall that being a thing specifically, yield return null will basically wait a frame though

[orchid abyss]

why isn't it working?

[swift falcon]

thanks, i'll try this out

[swift falcon]

have you called the function anwhere?

[vagrant blade]

Haven't you posted enough here to know that you need to give some context of what isn't working?

[orchid abyss]

when i instantiate the blood it rotates properly but otherwise it doesn't

[vagrant blade]

Baffling how anyone was supposed to gather that was the issue lol 🤔

[orchid abyss]

my bad

[swift falcon]

a screenshot would be great to understand your issue

[orchid abyss]

ill post a vid wait

[mossy snow]

bug 1) player.transform.rotation.y is a quaternion component, not an angle. You probably want to use eulerAngles instead
bug 2) capsulecollidercenter is probably not what you want; it's a world-space position, so if your transform ever moves it's going to be in the wrong place

[orchid abyss]

doesn't work either

[mossy snow]

I'm going to guess this is a logic error and that while your code says "rotate the blood around +y axis", what you want is "make the blood fly in the direction the player is facing" right? If it's "working on instantiate" why don't you just reuse that same rotation? Otherwise you probably want something like Quaternion.LookDirection(player.transform.forward); as your rotation

[orchid abyss]

this one worked but i swear i wrote it like this last time and it gave me an error 😅

something abount rotation not being a variable

maybe cause i added euler last time

[upper burrow]

I am struggling HARD with this code. No matter how much I add or change trying to get my snap grid to work, it refuses to let my pieces snap to the grid.

https://pastebin.com/RSRLvxwN
https://pastebin.com/4eWSFftD
https://pastebin.com/e6viKT4M

[cosmic rain]

Should probably start from clarifying/demonstrating the issue. A video could be useful for that.

[upper burrow]

True

[swift falcon]

i tried it...but lemme explain...i have two gameobjects...each gameobject has 4000+ gameobjects under it...when i am waiting for the frame after one chunk of gameobject is enabled, the whole process is taking only two frames...which is still creating heavy operation on those two frames resulting in screen freeze...and when i am waiting for a frame after each child objects is being active...it is taking way longer....what can i do now?

[fervent furnace]

Dont know terrain, but the how many objs you have not affect your strategy (split them up and disable partial of them each frame)

[marble mauve]

Yes it has

I want to quit from singletons but I have a ws connection so I think that I'll need one of them for the connection

I don't know if I can create a non-singleton in a class and call a function from that class without being a singleton as I don't have any instance of it. Only the behavior

[mossy snow]

if your singleton can be created on-demand, then you have two potential issues:

1. if it has any serialized fields, the one created on-demand won't have them set. And then when the one you set up is created, it kills itself
2. if it has any serialized fields, they have to have the same life cycle (i.e., if your singleton survives scene loads via DontDestroyOnLoad, anything it references has to as well or they'll be lost on next scene load because they're dead

[lean sail]

🤷‍♂️ splitting it across 2 frames is likely gonna have no real difference. you might need to do this across a lot of frames. This is basically gonna be the same as making those 2 objects into way smaller chunks. The problem is just flawed from the start, you arent gonna get good performance toggling 4000 objects on mobile

[swift falcon]

i guess i have to sort those objects and split it more efficiently...anyway thanks for the help

[marble mauve]

In my case my singleton (I don't know why I have created it as a singleton) is only in one scene because I don't know if in unity you can call a function from a mono behavior if you haven't set it to any game object

[mossy snow]

you might need to provide more context about what you're trying to achieve because I don't know how the second part is relevant

[spring creek]

If there is no instance of the class (whether it inherits from MonoBehaviour or not) then no, you cannot call a function from it

Just to clarify for the second part

[marble mauve]

I am trying to set a tmp text when I receive a specific message from my websocket. But as the text is disabled I don't know how I can get it. I could make it to be enabled when the message is received but when I set it to active and I try to change the text it turns me the error. I am executing a function from the ws singleton to another singleton that is invoking an event to make it active.

[marble mauve]

Oh thanks.

[faint hornet]

Hey everyone, quick question.. my game is little by little slowing down exponetially and i think it may be this code..

void RenderSprites()
  {

    RenderTexture targetTexture = cam.targetTexture;

    Texture2D tex = new Texture2D(targetTexture.width, targetTexture.height, TextureFormat.RGB24, false);

    RenderTexture.active = targetTexture;
    tex.ReadPixels(new Rect(0, 0, targetTexture.width, targetTexture.height), 0, 0);
    tex.Apply();

    Sprite convertedSprite = Sprite.Create(tex, new Rect(0, 0, tex.width, tex.height), new Vector2(0, 0));

    if (spriteRenderer != null)
    {

every frame in update is running this code, and i have reason to beleive that when i create a sprite i must delete it afterwards? i think this is a memory leak possibly? lmk what you think

[glacial pasture]

soloution

[cosmic rain]

Don't cross post...

[glacial pasture]

is this your server?

[cosmic rain]

It's in the server rules.

[glacial pasture]

ohk sry

[hexed pecan]

You are creating a new Texture2D every time you call RenderSprites.
Texture2D, like other objects inheriting from UnityEngine.Object, need to be destroyed manually or you get a memory leak, which explains the slowing down over time

[faint hornet]

so where and how should i delete it?

[hexed pecan]

You use Destroy to destroy a UnityEngine.Object

Destroy it when you no longer need it, or create just one texture and reuse it

Not sure how you are using it, but from what I see, you probably should just reuse one texture

Oh, and I think the same goes with the Sprite that you are creating. That's also a Unity object

[faint hornet]

can i use this ? or does this not destroy it?
tex.hideFlags = HideFlags.HideAndDontSave;

[hexed pecan]

That does not destroy it, no

https://docs.unity3d.com/ScriptReference/HideFlags.HideAndDontSave.html

[faint hornet]

so how do i reuse it?

just save a reference to it and then rewrite it?

[hexed pecan]

Create it once and store a reference to it

Yeah

[hexed pecan]

Sprites too ^

[hexed pecan]

To be clear, don't replace the object reference. Use the same object

[dawn nebula]

Finally, Silksong.

[faint hornet]

so would this work?

private Texture2D tex;
^^^ global


if (tex == null)
    {
      Texture2D tex = new Texture2D(targetTexture.width, targetTexture.height, TextureFormat.RGB24, false);
    }

no that is not working...

[hexed pecan]

Instead of Texture2D tex = ... you should do tex = ...

Otherwise you are creating a separate local variable with the same name, tex

Also ofc that if-statement needs to be inside a method

[mystic gull]

I have maps (type of Tilemap). When OnBecameInvisible I want to signal a MapManager that map is outside a screen.
When the map is instantiated by the MapManager should I:

1. Make a reference to the MapManager and call a method from it;
2. Make an event on a map and subscribe MapManager's method to the event. Notice I have 200 maps instantiated at the start so that is 200 subscriptions.
3. Other options or patterns I should use in this situation. Performance has more priority.

[faint hornet]

so doing,
tex = new Texture2D(targetTexture.width, targetTexture.height, TextureFormat.RGB24, false);
with a global reference will delete overwrite the current texture if it already exist, and will create one if it is null?

[hexed pecan]

Nothing here is 'global'

You probably mean member/class variable

If you do that and the texture already exists, the old texture will still remain in memory and you get a memory leak

Which is why you should only create a new one if it is null

[hexed pecan]

Just do this but remove the Texture2D as I instructed

[faint hornet]

@hexed pecan
ok so does this make sence for the array or sprites im creating?
old way

Sprite[] sprites = new Sprite[rows, columns];

Sprite slice = Sprite.Create(sprite.texture, new Rect(xPos, yPos, sliceWidth, sliceHeight), new Vector2(0f, 0f));
slice.name = string.Format("[{0},{1}]", x, y);
// Store the reference to the slice in the array
sprites[x, y] = slice;

new way

if (sprites == null)
{
  sprites = new Sprite[rows, columns];
}

if (sprites[x, y] == null)
{
  Sprite slice = Sprite.Create(sprite.texture, new Rect(xPos, yPos, sliceWidth, sliceHeight), new Vector2(0f, 0f));
  slice.name = string.Format("[{0},{1}]", x, y);
  // Store the reference to the slice in the array
  sprites[x, y] = slice;
}
else
{
  sprites[x, y] = Sprite.Create(sprite.texture, new Rect(xPos, yPos, sliceWidth, sliceHeight), new Vector2(0f, 0f));
}

[hexed pecan]

In the else you are still creating a new Sprite, which will, again, cause a memory leak

I don't really work with sprites but if you can change the existing sprite's rect and texture, do that.

If not, Destroy the old sprite before creating a new one

[faint hornet]

i do not know how to destroy a sprite. only gameobjects. i dont understand how to

[hexed pecan]

Destroy takes a UnityEngine.Object as an argument

GameObject, Sprite, Texture2D all inherit from UnityEngine.Object

[faint hornet]

so like this will work?

else
  {
    Destroy(sprites[x, y]);
    sprites[x, y] = Sprite.Create(sprite.texture, new Rect(xPos, yPos, sliceWidth, sliceHeight), new Vector2(0f, 0f));
  }

[hexed pecan]

Looks ok

What are you making though? There might be a more optimized way of doing it

Instead of creating and destroying objects every frame

[round violet]

what is the bool operation name that returns true if both statements are false

this

if (!statement1 && !statement){
}

[thin aurora]

Yes, that

[round violet]

im asking about the name

like "or", "and", "nand", "xor"...

if it exists for that

[thin aurora]

Oh

&& is conditional and

|| is conditional or

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/boolean-logical-operators

[round violet]

sounds like there is no "name" for what i am looking for

[mellow sigil]

There's no special name for that. It's an AND operation of two negations.

[mild coyote]

what about NOR? 😆
if(!(statement1 || statement2))

[cosmic rain]

Pretty sure it's called NAND in electronics and stuff.

You don't see the term in software engineering much.

[mellow sigil]

NAND would be !(statement1 && statement2)

[cosmic rain]

Ah, right

[round violet]

oh ty, i swear i looked at it before asking

[mellow sigil]

(!statement1 && !statement2) has the same result as NOR but nobody would ever describe that code saying that it's NOR

[faint hornet]

I am making a jigsaw like puzzle game, where the "completed jigsaw image" is animated using the camera to project UI component animations into the jigsaw pieces using sprites (so rentertex to tex2d to sprite multimode). the game basically relies on motion within the jiggies to solve, otherwise would be kinda impossible.

[warm kraken]

hey guys. i have 2 scripts. 1 is PlayerController and 2 is MouseLook. i use rigidbody to controll the player (move) so it causes slight jitter while also moving mouse/looking around (environment objects jitter). this of course doesnt happen when i switch to transform based movement on my PlayerController. any ideas how i can have rigidbody movement based PlayerController and MouseLook but fix the jitter? thanks.

[cosmic rain]

Enable interpolation on the rb.

[warm kraken]

didn't fix it

[mild coyote]

is mouselook using lateupdate?

[deft timber]

what mouselook?

[warm kraken]

Doesn't matter update type, still jittery

[trim schooner]

How are you moving the camera? It might be camera jitter, not player

Make sure the RB movement is in FixedUpdate too

[trim schooner]

Yes there is

[vestal crest]

would you tell me what is it name or link me the docs?

[warm kraken]

My camera script works in update and playercontroller in fixedupdate because it uses rigidbody

I think thats the reason because i use fixedupdate for my rigidbody. But there's no other choice

[trim schooner]

change the camera update to be FixedUpdate or LateUpdate

[placid compass]

Hello, I have a question. I have a prototype I want to test on my phone so I started android build. I have a pretty powerful pc but I have never had build take this long. The project is fairly small so It makes no sense to me why it is taking so long. It is the first build of this project but still. Any ideas? Unity is 2021.3.0

[latent latch]

what's your alternative

right, that's called object pooling and that's a concept you'd probably want to get familiar with

somewhere along the line you need to instantiate your objects into the scene, but it's not just the overhead of instantiation that's the problem but if you're actively destroying objects and re-instantiating then you may run into issues of performance hiccups at runtime

for a few objects it's probably not that big of a deal, but for example you've got a gun that's instantiating hundreds of physical bullets a minute, then that's something to consider pooling

if you're going to be reusing the object a lot, then you'd probably be best off just disabling it than outright destroying.

yep, sounds fine

I wouldn't worry too much until you do run into performance problem

[placid compass]

When you pick items up, they dissapear from the floor and appear in the hand?

if yes, then just move them there

set their parent as the hand and position at the correct position on the hand

no need for spawning or enabling/disabling the objects

[placid compass]

you can make a positioner object in the hand and set parent to it with position and rotations to Vector3.zero

Not sure for mp, but I dont see the reason it wouldnt work. If the object can be interacted with by every player, it shouldnt be a problem, but maybe ask in the networking channel

[midnight void]

[orchid abyss]

how to refer to child object of instantiated prefab?

[round violet]

Is Destroy called at the end of the frame or directly ?

[rigid island]

end of frame iirc

[knotty sun]

neither, after Update

[rigid island]

https://docs.unity3d.com/2017.3/Documentation/Manual/ExecutionOrder.html

[round violet]

ty

so yeah its at the end

like a scene load

[round violet]

i missread with OnDestroy mb

[rigid island]

so after the frame end?

basically

Actual object destruction is always delayed until after the current Update loop, but will always be done before rendering.
hmm

[warm kraken]

when i do that lateUpdate gives same result as Update. and fixedUpdate gives a little different result. it jitters as i move and also when i stand and look around, it feels laggy.

[orchid abyss]

my object falls through ground then i add force to it even tho it has a box colider and rigidbody

[placid summit]

anyone write xml comments for doxygen etc? The xml 3 line minimum seems a bit space-taking! I realised you can do a single line 3 slash /// comment instead, I think can not be // but //! or ///

[trim schooner]

this is a code channel and that's not a code issue

[quaint rock]

my editor just auto builds out the string when i hit /// including the ones for params, but it does both open and closing tags inline for those with just summary on 3 lines

dont really think the spaces it takes is a huge deal, since am really only putting it on public and sometimes protected methods anyways

[placid summit]

yeah mine too, though can toggle. But the text gets really spread out for say an interface if you add 3 line comments imho

still if its standard...

[lavish frigate]

When using unity ruletile, is the right approach to seperate my grass (walkground) from my ground (walls and roofs) for example?

or can i just throw it all together, even if my tilemap is big

[orchid abyss]

i switched from ontriggerenter to oncollisionenter and now it dont work

[deft timber]

ok

https://docs.unity3d.com/ScriptReference/Collider.OnCollisionEnter.html

[placid compass]

write

``` above the if statement. To see  if the collision is detected at all. If there is no collision, objects are not set up correclty

[orchid abyss]

oh i bet its caused by the skin width of the character controller again

-_-

[placid compass]

for collisions both objects need a collider and one of them needs rigidbody

[deft timber]

non-kinematic rb

[orchid abyss]

how to get around that

its already non kinematic tho

[lavish frigate]

is there a way to make ruletiles only interact with themselves? so if i place another tile above it which is not a ruletile it should not change

[mossy minnow]

hey, can someone help me clamp my fps camera to -90 and 90?

        Vector3 newCameraRotation = camHolder.localRotation.eulerAngles;

        newCameraRotation += (Vector3.right * -inputView.y);
        newCameraRotation.x = Mathf.Clamp(newCameraRotation.x, 0, 90);
        newCameraRotation.x = Mathf.Clamp(newCameraRotation.x,0, 270);
        camHolder.localEulerAngles = newCameraRotation;
        transform.Rotate(Vector3.up, inputView.x);```

problem im having is that looking straight up is 270 on the X euler

and looking straight down is -90

so its kinda hard to get a clamp that does both if that makes sense

[deft timber]

      newCameraRotation.x = Mathf.Clamp(newCameraRotation.x, 0, 90);
      newCameraRotation.x = Mathf.Clamp(newCameraRotation.x,0, 270);

you know that the 1st line

does completely nothing

as you are overriding it in the nexxt line

[mossy minnow]

yes

[deft timber]

ok

[mossy minnow]

i know it doesnt work

[late lion]

Instead of relying on the Transform to store the current rotation, it's best to store the two angles yourself and then create the rotation from scratch with those angles and overwrite the transform's rotation with the newly created rotation. That way, your angles can be negative and you can clamp them before you create the rotation.

For example:

private Vector2 cameraAngles;

private void Update()
{
    cameraAngles += inputView; // assuming inputView is where you get your camera look input.

    // Clamp the y (vertical) angle
    cameraAngles.y = Mathf.Clamp(cameraAngles.y, -90, 90);

    Quaternion rotation = Quaternion.Euler(cameraAngles.y, cameraAngles.x, 0);

    camHolder.localRotation = rotation;
}

[mossy minnow]

makes sense, thanks. since my Y rotation is being done on the whole player and the X is on just the camera, how would i go about just changing one rotation axis of each object? is localEulerAngles.Set() alright for doing that?

or would i have to turn it into 2 vector3s and just do it like that

or i guess i can turn them into quaternions

[late lion]

Then you only need to worry about the X angle. The example becomes:

private float cameraAngle;

private void Update()
{
    cameraAngle += inputView.y; // assuming inputView is where you get your camera look input.

    // Clamp the angle
    cameraAngle = Mathf.Clamp(cameraAngle, -90, 90);

    Quaternion rotation = Quaternion.AngleAxis(cameraAngle, Vector3.right);

    camHolder.localRotation = rotation;
}

I opted to use Quaternion.AngleAxis instead of Quaternion.Euler to create the rotation here. Both would give you the same rotation, AngleAxis is just a simpler method that works here because we only care about one axis.

hey y'all, who's familiar with Behaviour Tree, Behaviour designer in unity, i need help

[stone hare]

i need a lil help

my health bar fills with a delay any1 has any idea why

like im setting the bar to max on an input but it doesnt fill it until i sprint again

[vital granite]

In need of help in fixing a movement issue
Idk why but for some reason I'm locked to moving left and right and when I try moving backwards it suddenly starts going extremly high up and when I try going forward it causes me to start going down
I think it's due to MovePlayer() but I'm not sure what exactly is the issue with it

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

public class PlayerMove : MonoBehaviour
{
    public Transform camera;

    
    [Tooltip("Speed")]
    [SerializeField]
    private float speed = 5;
    float hInput;
    float vInput;
    Vector3 moveDirection;
    private Rigidbody rb;
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    void Update()
    {
        hInput = 0;
        vInput = 0;
        
        if (Input.GetKey(KeyCode.W))
        {
            PlayerInput();
        }
        else if (Input.GetKey(KeyCode.S))
        {
            PlayerInput();
        }

        if (Input.GetKey(KeyCode.D))
        {
            PlayerInput();
        }
        else if (Input.GetKey(KeyCode.A))
        {
            PlayerInput();
        }

    }

    private void FixedUpdate() 
    {
        MovePlayer();
    }

    private void PlayerInput() 
    {
        hInput = Input.GetAxisRaw("Horizontal");
        vInput = Input.GetAxisRaw("Vertical");
    }

    private void MovePlayer()
    {
        moveDirection = camera.forward * vInput + camera.right * hInput;
        rb.AddForce(moveDirection.normalized * speed, ForceMode.Force);
    }
}

[modern creek]

FixedUpdate can happen more than one time per frame. You're also setting hinput/vinput to 0 every update - you should just set them whenver input changes (or every update loop is fine)

also, use !code please

[terse quarry]

My user can spawn objects into a simulation and save the current scenario as a preset that can be loaded later. When they go to the load preset menu, I want the list of presets to have an image beside each one showing what it looks like. This would involve screenshotting the simulation when it is saved, but I don’t really know how to implement this, nor how to use that screenshot after it is taken during runtime.

[modern creek]

you can use ScreenCapture.CaptureScreenshot() to get an actual screenshot, but that's gonna get everything, and it's hard to know when you want to take the shot. You could also grab it from a camera in the scene.

Once you've got it, you'll have to make it available to the app - not sure of the best way to do this but I'd (personally) write it out to a file and load it into a texture in the preset menu. This might not be the best approach, I'm not aware of what unity has out of the box for stuff like this

[terse quarry]

Oh the camera to screenshot a section is a good idea

Does it have the option to screenshot from the camera instead of the whole screen

Rather, how

[modern creek]

no - that's just generally for "entire-screen" captures

you wanna dig into "render textures from cameras"

depending on the size and nature of your presets you could have a .. box? with the stuff in them, and a camera pointed at the stuff in the box, and be rendering the camera's output directly to a texture that you show in the preset menu

ie - the textures would be "animated" and showing movement and stuff

that might be overkill but .. it's possible

[terse quarry]

if the list had 2 presets with 2 different scenarios but the camera would only be able to look at 1 simulation at a time

[modern creek]

you'd have a camera for each

[terse quarry]

So I’d have to run multiple simulations?

[modern creek]

yeah

[terse quarry]

Unless Unity has superposition

[modern creek]

i dunno what these are, but... imagine they're levels? or something, like I'm thinking mario maker - you'd spawn the level somewhere off screen, including a camera and a bot to "play" the level, and then on the preset menu, show a UI that's showing a render texture from that camera

and you'd do that for all of your simulations

[terse quarry]

It’s a 2D space simulation

N body gravity

[modern creek]

hm, probably complex cpu-wise

so in any case, when you're in level design, you'll have some camera in the scene, snap a render texture and write it out to a file, then use that texture later in your preset menu

[terse quarry]

Will do

Thanks a lot

[bright maple]

btw dont hesitate to ask me questions, youd probably not want to read through a big thread to understand the code situation

[modern creek]

i think the key methods/apis you want to dig into are render textures, LoadImage(byte[]), and finding a place to stuff this byte[] data - I typically just throw stuff in the player folder and use File.WriteAllBytes() and File.ReadAllBytes() but your usecase might be different

[stone hare]

if (Input.GetKeyDown(KeyCode.R)) { stamina = maxStamina;}
im using this in update function and it seems to update it after i sprint again yall know how to fix it?

[naive swallow]

If that is in update, then every frame that you press R you will set Stamina to max stamina

[stone hare]

i am getting this issue

[naive swallow]

When do you update the bar

[stone hare]

on pressing R

[naive swallow]

That updates the stamina variable. What updates the bar

[stone hare]

staminaBar.fillAmount = stamina / maxStamina;

if (run == true)
{
stamina -= dValue*Time.deltaTime;
if(stamina < 0) stamina = 0;
staminaBar.fillAmount = stamina / maxStamina;
}

[naive swallow]

How about just show the full !code

HEY GUIS SHOULD PHYSICS CODES GO IN UPDATEZ OR FIXEDUPDATEZ

[wide raft]

Using Microsoft Speech SDK, when i stop playing i get an error: "Cannot dispose a recognizer while async recognition is running. Await async recognitions to avoid unexpected disposals." Problem is that the natural place to do this disposal is in OnDestroy ? making my Dispose function async won`t be ideal if in OnDestroy?, so kinda lost on this one.

[naive swallow]

So, the bar only updates while you're running. If you press R while you are not running, your stamina is refilled but you never tell the bar to update

You should update the bar if you refill it as well

Also your Recharge coroutine does nothing but you also aren't using it anywhere so I'm guessing it's just unfinished

[stone hare]

yes the recharge is not finished tks alot

AddForce should probably go in FixedUpdate, if it's using a time-dependent ForceMode. Velocity changes are probably fine to do in Update, since those are usually fairly constant

Omfg I think I just realized what the issue with my code is

my camera is following my rigidbody character. camera view was jittery due to rigidbody movement script using fixedUpdate and camera script using Update. after i lowered fixed timestep value it fixed the jitter. i was wondering how this will affect my project. is this a valid fix?

but I still had FixedUpdate() jitter problems I think

you could use a statemachinebehaviour to trigger it instead of animation events (assuming that is what/how you're doing it, in the first place)

[carmine cloud]

I didn't set up the character, I'm just the one working on fixing bugs with it now that the guy who did is no longer here, so... if there is a more standard way of doing it then I'm all ears, this seems very much like un-intended behavior

[shrewd hornet]

yeye, that shows one event trigger out of 8, set on that individual graph node..
..but you could have a state machine behaviour, at the 'higher level' that sits on the actual graph itself and looks at overall progress and then fires an event.

i believe, but then, i'll be honest ive never tried to mix and match animation triggers like that, and i have found that weird things happens when you start blending things with triggers and triggers contained within 'transition periods' of the animations

[carmine cloud]

I've had issues with transition periods too, that was a thing I checked already, there isn't any transition period on this one at least so I ruled that out

[vital granite]

Okay I was able to fix the flying issue now I'm just stuck with the issue where the player is stuck to moving only on the x axis
How do I fix this code to allow it to move on both the x and z axis?

Hello, in my project I use Cinemachine camera. I Discovered something weird. I have kinda jittering effect when moving the camera. There is stable 60fps in build. Players complains about motion sickness with this. This effect I can see even just rotating around the camera without players movement.

I tried many things from google like:
-changing cinemachine to works on lateupdate/fixedupdate
-rigidbody's has interpolate/extrapolate
-updating cinemachine, unity
-vsync on/off
-disable any post proces effect like blur
-forcing cinemachine to follow a separate gameobject with rigidbody, and that gameobject force to follow the players eye

nothing of this change anything. This problem happens in editor and build

Is anyone here have other solutions?

CM brain needs to use the same Update method that your movement is using

[vital granite]

Update turns I was just an idiot who didn't realize that at somepoint I locked my z position
no wonder I was only able to move on one axis

[dense estuary]

How can I make a bool that becomes true for a little while after IsGrounded() = false?

[vagrant blade]

When it becomes IsGrounded = false, start a timer.

[marble mauve]

Now I tried to set an string property to a singleton and then adding an script to the tmp text that updates the text every frame with the text in the singleton but the same error is thrown when trying to set the string variable inside the singleton

[dense estuary]

Using a coroutine?

[vagrant blade]

I wouldn't, I would just track it in Update so it can be interrupted easily.

[dense estuary]

how long should the timer be?

[trim schooner]

it should be as long as you need it to be

that's a game design choice

[vagrant blade]

How long do you want it to be 🤔

[dense estuary]

idk, I just need a way to set a variable true for a short amount of time, when another variable becomes false. So, idk, 0.5 seconds?

[vagrant blade]

Sure?

The amount of time is irrelevant here

[dense estuary]

My current issue is the way I'm thinking of doing it, the timer would restart every frame that IsGrounded() = false how can I know when IsGrounded() just became false?

[hard viper]

i do not have timers. I log timestamps.

[vagrant blade]

You will need to cache the previous state of IsGrounded such that when it becomes false, you can check the previous one for if it was true. If so, you can handle what to do.

[hard viper]

The timestamp method is really good for this in player movement. Specifically timestamps for: when jump button pressed, when jump button last released, and when last was grounded

Then check if you still count as grounded/jumping etc by comparing timestamp of when that event just occurred to Time.time, with some buffer window

private const float JUMP_BUFFER_TIME = 0.1f;
private bool JumpInputActive => timeLastJumpInput + JUMP_BUFFER_TIME < Time.time;```

like this

this makes it extremely easy to implement buffered jump input, coyote time, and controlled jumps (aka jump cut aka short hop)

and because you aren’t juggling bools turning them on/off, it is a lot easier to keep track of your player state. I can’t recommend this method enough

[hard viper]

repeat for time last grounded, and again for time you last let go of the jump button

[trim schooner]

And you're just using the current system time for that?

[dense estuary]

Currently when the player goes onto a downward slope they get pushed up about 1 unit off of it? Here is my script: https://hastebin.com/share/oholojahaw.csharp. Here is a video: https://streamable.com/eb8f7d

@dense estuary this may be of interest: https://catlikecoding.com/unity/tutorials/movement/surface-contact/

[dense estuary]

It isnt flying upwards do to physics, I'm using CharacterController, it is floating exactly 1 meter off the ground.

and it also isnt sticking to the ground

[faint hornet]

Does it matter if you move the gravity function above the snap to ground in update? have you tried that?

maybe i'm wrong but my intuition is that you should do all movement first then do snaping. the cam function can be placed anywhere but if it follows the player it should come after

[hexed pecan]

The page Carwash linked is not specific to rigidbody, if thats what you mean. Pretty sure you can apply it to CC movement too

[dense estuary]

The gravity function just sets the variable for gravity, currently it isnt being applied.

[dense estuary]

I'm looking into it rn

[faint hornet]

hmm ok, also i think this script is much too complicated for what you are trying to acheive.. anyone have thoughts on that? (it's not complicated, just could be alot simpler)

[dense estuary]

Yeah, it kinda hurts to look at, all I'm trying to do is make a character that can walk on or off slopes and jump. But everything I try I get a bunch of issues.

[faint hornet]

yes, if thats all you are trying to do, this is wayy over complicated.. let me think of approches to simplify

it' there any way to create a ws connection which perdure between scenes without doing a singleton?

[faint hornet]

@dense estuary why arnt you using a rigidbody to handle this stuff?

[swift falcon]

I am trying to make an object shrink in size when ever this specific script is called, how do I do so?

thats what I have done but it doesnt seem to work, please help me

[knotty sun]

maybe because localScale is a Vector3 and you are subtracting an int

[swift falcon]

oh so what should I do instead?

[rigid island]

https://docs.unity3d.com/ScriptReference/Transform-localScale.html have you bothered rtfm?

[knotty sun]

well, what do you think would make a Vector3 value smaller?

[swift falcon]

well that is for the 3d version...

this is unity 2d

[knotty sun]

the same

[dense estuary]

Because when I used a rigidbody the movement was super buggy and I could never figure out why. Also, I want to be able to stick to platforms going down.

[rigid island]

Unity is a 3D engine, anything that applies to 2D applies to 3D

the only thing that changes is the Physics engine in the backend

[swift falcon]

why doesnt this work tho? @knotty sun @rigid island

[little meadow]

because structs and properties

[swift falcon]

so how would i fix this?

[rigid island]

what does error say

[rigid island]

that aint it

[little meadow]

also, because you need a vector3

[rigid island]

thats the one

[little meadow]

it's both, no?

[leaden ice]

you need to read your error messages

[rigid island]

nah the -= is valid since its subs from another v3

they're using v2 but the original prop is v3

[little meadow]

right, right, me being slow-brained today 😅

[swift falcon]

wait, if i want my script to change the sprite of the object to a different sprite from a spritesheet?

[leaden ice]

What's the question here?

how to change a sprite?
mySpriteRenderer.sprite = whateverSprite;

[swift falcon]

okay so basically i have this spritesheet and i want it to circle through the different dice in the sheet

[leaden ice]

for which of course you need references to the sprite and to the renderer

[rigid island]

put them in array

[swift falcon]

could you please help me with that?

im new w arrays

[rigid island]

just do [] and now you have array

[swift falcon]

well ik that far

[rigid island]

eg public Sprite[]

[rigid island]

so pick one from the array when you need it, its easy that dice face 1 will be at position 0 and so on

I have a script which creates shadow casters from a tilemap collider,
I want to modify the shadow casters to look something like this, how could I even aproach this, any ideas?

[hard viper]

option 1: Make an animation with the sprites, which allows it to be handled via animator on a gameobject.
option 2: Turn them into an animated tile, which can be managed on a tilemap.
option 3: Individually reference each value separately by serializing an array in a monobehaviour or scriptableobject, and assigning each sprite into that array.

You probably want option 3, so you can more cleanly reference specific values.

[simple egret]

From docs:

If nonzero, this number will be compared to the checksum of the downloaded asset bundle data. If the CRCs do not match, an error will be logged and the asset bundle will not be loaded. If set to zero, CRC checking will be skipped.

It's like a hash, for data integrity checking. At a low level, networking packets use some kind of CRC so the receiver can see if it got altered during transport, to request a resend

Checking if the asset on disk is up to date with what's online is done with the hash argument, not the CRC. The latter is purely for download integrity checking

Hi. I have one singleton (WebSocketManager) which calls the function SpawnQuestion of another singleton which contains in its properties a TMP_Text field. I set the field before runtime in the start method it's logged with a log but when I call the function spawn question and I set the text it turns me an error: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: Cannot perform runtime binding on a null reference

I don't know why. It has been occurring to me since yesterday. I tried to quit from singletones but I can't as I switch between scenes and I want to mantain ws connection open.

I need help.

https://pastebin.com/AhykNggA

[simple egret]

The usage of dynamic is probably the cause. Have you modified your JSON structure since the last time it worked fine? Dynamic resolves and binds the values you access at run-time (which makes it extremely slow), so it might just be a NullReferenceException in disguise. Maybe on line 145 data.metadata is null, and trying to access .type on it throws that exception?

Honestly I'd drop the dynamic stuff altogether, it removes one of the core features of the language: type safety

And rethink how the data is transmitted

[leaden ice]

you won't be able to use dynamic in IL2CPP btw

[marble mauve]

I am sending in the proper way but I'll double check it. I am using dynamics as I am not used to working with such complex types I need for my protect. I think the typing between typescript and c# id different so I don't know how to make generic types as in ts.

[leaden ice]

Json.NET has alternative approaches that don't use dynamic. Switch to those

[faint hornet]

what unity library uses StartCoroutine(); ?

[simple egret]

The base message could be something like this:

class Message
{
    public MessageType Type { get; }
    public string Payload { get; }
}

And you do your if statement on the Type, and the Payload contains a JSON string you'll deserialize to another class. No need to make it complicated

[marble mauve]

For example I want to make the JSON having the metadata object the same in all the messages but having different payloads

So ```cs

class Message {
public metadata //metadata obj

public payload

}```

dfferent payload values are possible. Having made the clases for the different payloads how to set them as a type

[faint hornet]

@leaden ice Oh is only MonoBehaviour?

[leaden ice]

Yes StartCoroutine is a method on MonoBehaviour

[simple egret]

if (message.Type == MessageType.Whatever)
  value = JsonConvert.DeserializeObject<WhateverThing>(message.Payload);

if (message.Type == MessageType.SomethingElse)
  value = JsonConvert.DeserializeObject<SomethingElseThing>(message.Payload);

Something like that?
You basicallyhave two deserializations. One for the whole message, and one for each specific message type

[leaden ice]

As per docs https://docs.unity3d.com/ScriptReference/MonoBehaviour.StartCoroutine.html

[vale bridge]

are coroutines kind of like context switching?

or like waiting for a child process before continuing

[simple egret]

Neither

They're iterators, functions that return different values when you call them multiple times. Unity hijacks that feature to get the return value, and delay the next call to the iterator

It does not run in parallel, nor in a different thread

[vale bridge]

Well context switching isn't parallel nor a different thread either but I get your point

[simple egret]

I thought it was storing the state of the program so it's recalled whenever another task has completed

Looks like Wikipedia has that definition too

[vale bridge]

oh sorry I kept forgetting that there's two types of parallelism, I was thinking of the hardware one that's mb

[simple egret]

You could say it stores state though, as the iterator is compiled into a full class so it knows where the execution is, and what to execute at the next call

[vale bridge]

Mhmm

I was reading the example provided on the official documentation and had a few questions

If I have a for loop that yield return new WaitForFixedUpdate() every loop, do I have to explicitly stopCoroutine() or something like that

[vale bridge]

Also by this description, it seems to me that Unity hijacks the execution process where you write the yield... and waits for the condition to fulfill itself before it continues execution, is that right? Like an interrupt that continues only after you handle it

[simple egret]

It's like the foreach loop, it generates a MoveNext() function and a Current property to advance through the iterator. Unity uses that at some point to know whether the coroutine has ended, and what (and how long) to wait for, respectively

[wicked scroll]

maybe this very old post helps https://jahej.com/alt/2011_07_07_unity3d-coroutines-in-detail.html

[simple egret]

Yeah the internals of coroutine handling might be done on the C++ backend, so most likely closed-source

[vale bridge]

thanks regardless, very informing!

[simple egret]

If said loop is infinite, and you want to stop it at some point, then yes. Otherwise it'll keep running for as long as the Game Object the coroutine has been started on is alive and enabled

[mental rover]

an important part of understanding Coroutines is the Unity message loop: https://docs.unity3d.com/Manual/ExecutionOrder.html
it's easy to think it's black magic how Unity "comes back" to the Coroutine, but it's all running on the internal message loop in a very similar way to Update() - this is where calling Next on the iterator happens

[stone loom]

Wondering If anyone can give me some feedback, had a call/meeting today and towards the end i feel like I humiliated/embaressed myself,

But I was asked if i understood how to use the Profiler, and i said I'd "Never actually used it on a build, and don't have an in-depth understanding of it, but I do use it on a basic level to check texture memory, CPU spikes," that kind of thing.
And I was asked I think "How would I go about debugging a 100% reproducible 'Out Of Memory' " bug on a device, or even in the Editor,

My answer was to "check any logs that got generated," and then take a look at "what was happening in the scene" when the crash happens, and narow it down from there.

Shortly after everyone had to leave the call, and maybe it was just bad timing but it felt like maybe I'd missed some super beginner answer that I just shouldv'e known, depsite mentioning I don't have too much profiler experience,

Anyways, was wondering if anything stands out to any of you as an obvious response.

I also think I said "If there's a specific way to go about that, I don't think I'm familiar with it." This feels like something I shouldnt have said/was the dealbreaker

[mental rover]

maybe more suited to a different channel, but Unity has a memoryprofiler package specifically for analysing a snapshot of memory where the profiler is more useful for performance profiling (though at a glance shows allocations & a rough idea of memory use)

[cosmic rain]

They probably expected you to answer that you'd use the profiler to see what consumes most of the memory.

You can analyze the memory with the "classic" profiler btw, it's just more convenient with the new one(memory profiler package), since features like comparing snapshots are added, and overall it's a bit more precise and reliable.

[stone loom]

@cosmic rain I guess I assumed it'd go without saying that I'd troubleshoot it with the profiler open as well, but coming in knowing "this person doesn't have too much experience with the profiler," would not knowing about using Snapshots be something just too amateur?

[cosmic rain]

Typically, whatever engine you're using would have tools for debugging and profiling common issues, like performance, memory leaks, etc... I guess they expected you to know that.

[simple egret]

That's how I'd do it: filter the graph to only show memory usage, notice that it's going up over time, select the time frame where there's the buildup (so it filters the hierarchy below), search the list for what takes/allocates the most, and drill down until you pinpoint the exact method that's allocating too much memory

[cosmic rain]

You saying stuff about checking the logs and looking at the scene did sound like you don't k ow how to solve such issues,which was probably important to them.🤷‍♂️

[stone loom]

@simple egret so thats exactly what i do now- thats kinda i guess what I'm asking, thats the process i gave them,

and im wondering if they were expecting a specific answer

but if thats what stands out, then maybe I'm just overthinking it

[cosmic rain]

Just to clarify, SPR is talking about the workflow with the profiler. Not the hierarchy in the scene.

[simple egret]

If they didn't give you a specific project, or at least a profiling session file you could replay (if that's even possible), then no you cannot be more specific than this

[stone loom]

@cosmic rain inm not talking about the hierarchy in the scene. im talking about the profiler

@simple egret okay thanks. I just basically said "I'd check any error logs, then go back and check what was going on in the scene (within the profiler) at the time of the crash"

[simple egret]

The issue is that doesn't mention using the profiler at all

Out of memory will likely hard crash the game, producing very little to no logs

[wicked scroll]

We can't know what they expected but that doesn't sound like the sort of thing worth ending an interview over, so you're probably overthinking it and/or there were places you weren't a good fit. If I were asking that question, I'd want an answer like "Well what's our hunch about what's causing the leak? Did I work on the project and so have an idea, or is there someone I should ask who worked on that part and would know?" If it's 100% reproducible, presumably we know most of what's causing it already and the important part is getting that context, not 'use the profiler to profile' (which seems too obvious to be worth asking about to me).

[stone loom]

Well to be honest I can't really remember what I said, if I reiterated that I would be checking in the profiler whats eating the memory, CPU etc,

But I guess I thought It went without saying, If I'm familiar with the profiler and how it measures CPU usage and memory, that I would be using that as I went back to "check whats goin on in the scene."

But I don't know. Could be overthinking it.

thanks tho everyone for the help

And the call was more about my larger skills as a whole, just a brief touch on the profiler at the end

[vale bridge]

I'll look into it thanks

[narrow yoke]

.net 4.0 seems not support BitShift function in BitArray Class. Is there any alternative to do bit shift for BitArray?

[somber nacelle]

what are you trying to accomplish with bitshifting on a BitArray

[narrow yoke]

A memoryBitStream system to read and write pack from the packect. I take the reference from the code in a C++ project. Actually it's a C++ server and C++ client. I want to move some client basic part to C# and dev game with unity. Do I have to move the bitstream system? Or there's some built-in function? Idk...

@somber nacelle

[fervent furnace]

You need to work in bit level in cpp?

[narrow yoke]

Yup.But the tutorial project say it's necessary but didn't tell me why… maybe for security I guess? I wonder which case should write some several bits instead of a byte(8bits) ?

[fervent furnace]

You must add a byte since it is smallest unit cpu can deal with, afaik the only use case in writing (attach/remove bit from bit vector) in bit level is big integer

[narrow yoke]

Do u mean the case like the interger is greater than the max largest range of int could represents?

I didn't understand add a byte?where do I add? Do u mean bit shift to byte instead of bits?

[fervent furnace]

You can copy the source code online if you need it

[kindred wagon]

SystemInfo.graphicsMemorySize shows me 3072MB of VRAM on a Windows desktop system with an 4070Ti 16GB. I was expecting to see 16GB, not 3GB. SystemInfo.graphicsDeviceName correctly shows me "NVIDIA GeForce RTX 4070 Ti SUPER".

SystemInfo.systemMemorySize shows me what I expect.

Any idea what's going on or what I'm missing?

[leaden ice]

The former is maybe reading your integrated CPU GPU?

[kindred wagon]

Oh dear, that would be concerning if it wasn't reading the graphics size from the same GPU?

The machine has a Ryzen7800X3D, I wasn't able to easily find if 3GB is the right VRAM for that iGPU to see if that confirms it

[marble mauve]

But. Howw I can access message type without deserialize

I receive the type inside metadata.type

So what I thought it would work but I don't know if I can do it in c# is to set a type that could be all the payloads. And set it on the payload property

As the metadata property is always the same over messages

As I said I'm used to typescript and so in typescript I would only do Payload | Payload1 | Payload2 but I don't know how to do it in c#

[leaden ice]

you would write a custom JsonConverter for this in json.NET

[candid kiln]

is there a way to serialize not auto-implemented properties?

[leaden ice]

There are tons of ways to serialize properties

are you asking about some specific serializer though?

[candid kiln]

like, exposing it to the inspector

[leaden ice]

I.e. JsonUtility?

[leaden ice]

With Unity's built in serializer, you cannot serialize properties at all

only fields

[candid kiln]

:((

[leaden ice]

You can use e.g. OdinInspector or a custom editor

or NaughtyAttributes

[candid kiln]

even with propertydrawers?

[leaden ice]

if you want to expose properties to the inspector

[leaden ice]

PropertyDrawer customizes how a serialized field is drawn

it cannot make non-serialized properties get drawn

[candid kiln]

thanks

[marble mauve]

And how I can do it I am not used to do such complex thing in c#.

Wait, but in c# there is nothing to set a multi type property?

[quaint reef]

You can use generics

[leaden ice]

interfaces, abstract types, etc, yes.
There are no Unions though

[quaint reef]

You need to study it yourself, or see in Unity Asset store if you can find the thing you’re searching

[marble mauve]

But I want to set the returning type on NewtonsSoft deserialize as a message which contains all the payload types on its payload property and not a fixed payload.

[marble mauve]

So how I can make something which might work as an union

[leaden ice]

you can't

C# doesn't support unions

I don't see why you need one

use an interface or parent class

[marble mauve]

Because for each different message type a different payloads is sent

[leaden ice]

you either use an interface or parent class, or use multiple fields

[marble mauve]

So instead of setting a payload field I set all the field spread through the object and set them as no required (I don't know if I can in c#)

[leaden ice]

Not what I said

[marble mauve]

Or set the different payloads on different properties and set them as non required so I will have all the payloads

[marble mauve]

But what I said would fit in?

[cosmic rain]

That's gonna be a waste and simply a bade design decision. Just define several classes for each message type.

C++ unions are basically a lazy way of doing just that(excluding some complex cases that require memory alignment and stuff)

[mild coyote]

just make the payload as json string then you can parse the payload however you like 😆

not a best practice though

[fervent furnace]

You can create union by struct layout

[terse surge]

Is implementing a singleton pattern necessary to create an effecient way to calculate score? I feel like id be able to do it without

But then id need a reference to the score script indtance in every single projectile (since score is based on projectiles dodged in my game)

Im still unsure how this works exactly even after a few tutorials

How would singleton pattern exactly help me in this situation?

[cosmic rain]

No. Singleton is never a necessity and rarely recommended at all.

[candid kiln]

why is it rarely recommended?

[cosmic rain]

Because it's sort of an anti pattern.

[leaden ice]

I recommend singletons all the time...

they make things quite simple for simple projects

[cosmic rain]

It promotes undesirable coupling, makes testing and refactoring more difficult. In multithreaded context can create all sorts of issues due to accessing from several threads.

[leaden ice]

All of which are non issues in most simple projects

[cosmic rain]

I do agree that there is a place for them. I just say that it's generally not the preferred way if there is an alternative

[terse surge]

there is a solution for multithreaded situations

idk how it was but it wasnt a lot of code

[candid kiln]

what's the alternative? scriptableobjects?

[cosmic rain]

There is a solution for any situation. The question is viability.

[cosmic rain]

Pass your dependencies on construction, initialization.

[terse surge]

i dont remember the code, it was all new stuff to me but it didnt seem to be too diffuclt

you would use something called Lock? idk

[cosmic rain]

SOs can be fine. It's basically unity injecting the dependency for you.

[cosmic rain]

Yes, you'd use some sort of lock or mutex. That brings other potential issues though.

[terse surge]

oh i see

[cosmic rain]

Like a deadlock

Anyways, my point is singletons are never "necessary"

[candid kiln]

for every component? what if there is a soundmanager which we have to access from lots of places?

[terse surge]

how do you guys suggest i approach my score system?

I am planning to, OnDestroy, check if a projectile has interacted with the player, if it hasnt, the player gets more score, which then the total score would be displayed at the top. Currently i have an empty object called Game Manager that holds the score script. For my solution to work, every projectile would need a reference to the Game Manager to then increment the score in it. But i will be only having one instance of the class score, so maybe there is a better way to approach this?

[cosmic rain]

Don't access it from lots of places.🤷‍♂️

Raise an event in something that is not directly related to sound and handle it somewhere on higher level.

[candid kiln]

you could maybe be using events to get rid of the reference

[candid kiln]

maybe

[cosmic rain]

There might be situations, when a singleton would be viable. Depending on the context, Sound manager might be such a case. But there are some people who wouldn't use it in this case either.

[cosmic rain]

Maybe use events?

Raise an event OnDestroyed or something and subscribe from wherever you spawn it.

[candid kiln]

hi, i'm developing an online game and users can freely change their profile picture & account data. everything in account menu displays information from account data (account data is a static class that has a class called accountinfo inside, which json deserializes into). i'm currently updating the information by using a simple notifier for my profile picture but users may change lots of things (their nickname, etc.) in the future or there might be a modal that needs to display live information for a short time and i don't want to fill my account class with notifier methods. here comes the my question:
what do people do in this situation? should i use unirx for this or is it an overkill?
(moved from #💻┃unity-talk)

[terse surge]

currenly looking into it 👍

but i do have a question, how would a static method work in this situation? and if it wouldnt work, why not?

cuz an event seems to be just like an if statement with a static method inside

[cosmic rain]

It's fine if all the logic is static, but otherwise, you'd need an access to an instance somewhere.

Hard to say without seeing the code that you have in mind.

Hey everyone, currently trying to code an attribute system for my items, but I'm having trouble doing so in a flexible and neat way. This is my code so far:

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

[System.Serializable]
public class ItemAttribute
{
    public ItemAttributeType type;

    [EnableIf("valueType", ItemAttributeValueType.Float)] [AllowNesting] public float floatValue;

    [EnableIf("valueType", ItemAttributeValueType.Vector3)] [AllowNesting] public Vector3 vector3Value;

}

public enum ItemAttributeType
{
    durability,
    containerSize,
    gun_firemode,
    gun_magmode,
    gun_damagepershot,
    gun_bulletspershot,
    gun_ammo
}

public enum ItemAttributeValueType
{
    Float,
    String,
    Color,
    Vector2,
    Vector3
}

There are a couple of problems I'd like to solve, but don't know how.

• The value of the ItemAttribute class should ideally only be one variable, instead of 5 different ones that I have to choose between.
• The ItemAttributeType should have a key and a value, sort of like in a dictionary. For example "gun_magmode" should be key: gun, value: magmode.

I'm also open to suggestions on how to improve this in ways I haven't described here.

Thanks in advance for any help!

you do kow that C# has an object type, yes?

I know but how I can deserialize the JSON because it could be any type of message. Despite I design all the classes then I have to put one type only in the generic of the deserialize function

[marble mauve]

But how I can identify which payload is it I make it as JSON string but I can't know the type of message before I deserialize as I can't access metadata

Example:

{
"metadata" :{
"type": "any type"
},
"payload" : any payload
}

I can't identify the type if I don't deserialize it

I can check it with the string but it wouldn't be a nice way to do it

ah, the joys of JSON, solution: don't use json
