I incorrectly assumed everybody has low attention spans

[leaden ice]

Use a LineRenderer and raycasts

[main oxide]

bro can somebody please make me an anticheat for my game people have my apk and have all moderator items

[fickle birch]

I am using Raycasts, I'm mainly trying to write the logic for the script to scale down the Laser Sprite if the ray hits an Object in the middle that's not a Player

If I use Line Renderer, will I be able to use it with my Sprite?

[leaden ice]

I'm mainly trying to write the logic for the sprite to scale down the Laser Sprite
I mean isn't this dead simple? You position it in the center between the laser emitter and the hit point of the raycast, and just set the scale according to the raycast hit distance

[fickle birch]

I tried, but I'm not sure if it's correct, the output is crazy

    void UpdateLaserBeam()
    {
        // Cast a ray from the laser spawn point to detect ground objects
        RaycastHit2D hit = Physics2D.Raycast(spawnPoint.position, spawnPoint.right, 100f);
        if (hit.collider != null)
        {
            float distance = hit.distance;
            GameObject laserBeam = transform.GetChild(0).gameObject;
            laserBeam.transform.localScale = new Vector3(distance, 1, 1); // Scale the laser beam to the distance
            laserBeam.transform.position = spawnPoint.position + spawnPoint.right * distance / 2; // Position the laser beam correctly
        }
        else
        {
            GameObject laserBeam = transform.GetChild(0).gameObject;
            laserBeam.transform.localScale = new Vector3(100f, 1, 1); // Scale the laser beam to the maximum detection range
            laserBeam.transform.position = spawnPoint.position + spawnPoint.right * 100f / 2; // Position the laser beam correctly
        }
    }```

[leaden ice]

"crazy" how?

[fickle birch]

Like it jitters a lot because it's being called on Update() and it's like the 2d version of z fighting

[leaden ice]

Can you elaborate on what you mean by "jittering"?

maybe show a video

[fickle birch]

Like a toddler is drawing aggressively

[leaden ice]

that doesn't mean much to me. A video would be better

[fickle birch]

Okay, one sec pls

[leaden ice]

does your laser itself have a collider?

[fickle birch]

Yes

[leaden ice]

Your raycast is hitting the laser itself

you're not using a layermask

use Debug.Log to diagnose issues like this

You need to be checking what your raycasyt is hitting

[fickle birch]

Ohhh

[leaden ice]

if (hit.collider != null) {
  Debug.Log($"Hit {hit.collider.name}");```

[fickle birch]

🙏 Thank you, I'll try

[fickle birch]

It just says object

[leaden ice]

what does

If it says "Hit object" in the console then you have a GameObject in the scene named "object", and that's what it's hitting.

[gray mural]

Tools.current = Tool.View;

When called from Editor.OnSceneGUI, why does this line throw the following error and how would I fix it?

The targets array should not be used inside OnSceneGUI or OnPreviewGUI. Use the single target property instead.

[fickle birch]

Sorry I mean, it's printing the names correctly

But it's not working correctly still

[leaden ice]

printing the names of what correctly? What change did you make that would make it work correctly?

[fickle birch]

RaycastHit2D hit = Physics2D.Raycast(spawnPoint.position, spawnPoint.right, 100f, LayerMask.GetMask("Ground"));```

The Objects it is supposed to be blocked by are all on LayerMask ground

[leaden ice]

ok so... what's going wrong with it now?

[hidden flicker]

How could I subdivide a mesh at runtime? I want to have a square prism and be able to subdivide it into x amount of smaller squares

[fickle birch]

Still "jittering" like the video

Doesn't scale like intended

[leaden ice]

ok and... are you logging things? What is it logging?

Show the code, show the console

play the sound from a different object, or don't destroy the object until the sounds is done.

Or just use AudioSource.PlayClipAtPoint

[barren musk]

does anyone know how to make a gun shoot?

[supple ginkgo]

yo

[leaden ice]

https://dontasktoask.com/

[fickle birch]

https://hastebin.com/share/iqalohasuh.java

I'm not logging anything because the tracking and rotating is working, it's just the sprite scale adjustment that is buggy, which you recommended to debug now and I complied.

The problem is probably with the way the function is being called in Update or something, or maybe the logic for the scale adjustment is wrong itself

[leaden ice]

You're logging this:
Debug.Log($"Hit {hit.collider.name}");

You should probably also log something when it misses

see what happens when the jittering is going on

[fickle birch]

Okay

[fickle birch]

Null

[leaden ice]

what's null

[fickle birch]

It causes a Null reference exception when the ray misses because it's not hitting anything

If it is handled, it prints("Null")

[leaden ice]

obviously... you shouldn't be trying to print the name of nothing

I meant print something like Debug.Log("The ray hit nothing");

[fickle birch]

Sorry I haven't slept much today

It did print null, is there a way to see the Ray as debug line? I will remove the scaling logic and see what it's actually hitting?

[gray mural]

Yes, use either Debug.DrawRay or Debug.DrawLine

[fickle birch]

Thank you

[gray mural]

And don't forget about its parameter, time

[reef garnet]

Just started a new project and Unity is being funny with me, any time I save in Visual Studio unity recompiles which is normal, the annoying part is that it displays over Visual Studio and for a chronic Ctrl+S user like me it gets annoying very quick, is there a way I can stop this?

[gray mural]

It displays over Visual Studio
Does this mean, Unity's tab is put above Visual Studio's when you press Ctrl + S?

[reef garnet]

Yeah after a second or 2

[gray mural]

This has never happened to me

[reef garnet]

First time for me and it's a Unity Version I was working on in another project

[gray mural]

What version?

[reef garnet]

2022.3.32f1

[gray mural]

Maybe ask in #💻┃unity-talk, and I have no idea

[reef garnet]

ok

[indigo tree]

For player state logic, is it better to use a single data structure or classes that inheritance from each other to represent states?

[leaden ice]

there is no one correct way. It depends on the scope and requirements of your system

If it's relatively simple, just an enum and a switch statement are good enough

[indigo tree]

Fair point. My state machine is somewhat complex hense why I asked. I am currently doing some logic like this where each state corresponds to an enum and has an action attached to it.

I am currently just searching through this to find the state I want but I am worried that this won't be sustainable.

[leaden ice]

when you say "searching yhrough this to find the state" are you describing something you are doing as a developer to make code changes?
Or are you describing something your code is doing?

[spark stirrup]

whats the best way to save and load gameobjects from a scene while keeping all of their scripts and variables?

[leaden ice]

1. Create a data structure that holds all the relevant data you need to save
2. populate that object from your scene
3. serialize it and save it to a save file

for loading, do the reverse

[indigo tree]

The ladder. Well, I have a dictionary of the state data class. Whenever I want to assign a state I have the script search through the dictionary and return the corrisponding "StateData"

[leaden ice]

you do mean just accessing the dictionary by the key right?

Not actually "searching through the dictionary"

[indigo tree]

Yes. Of course

[leaden ice]

also latter*

ok I mean... seems fine to me so far

[indigo tree]

I always mess that up 😭

What I am more worried about it how I store the state data rather than how I obtain it.

For non constant ones, I'll probably have to create new states directly rather than obtaining it through the dictionary. Such as states that represent unique moves per characters.

So I can construct them or use a class for parameters.

[fickle birch]

@leaden ice Thanks for trying to help me.

Instead of spending 2-3 hours on this problem, I should have just reused my Grenade/Missile Launcher Prefab and increased the fire rate and Missile Sprite

🤡 🔫

[flint panther]

                    Vector3 handsDirection = other.Hand.position - Hand.position;
                    targetRotation = Quaternion.LookRotation(handsDirection);```

Very simple yes

Why it does this

The gun seems to flip around when going to a certain angle

I believe that angle is precisely aligned with the negative z axis

Uh yeah?

Any of your public spell derivatives will automatically be able to access the base spell variables

If your IceSpell inherits from Spell you do not need to get any component

It is a spell

It can access the spell variables

Yes. If another script is accessing icespell, it can access all of the public base spell variables too

I'm confused. Can you share what this is for

Example

And I am telling you, that your spellCaster script can just access the spell variables
If you're storing the prefs as gameobjects, then don't do that, store them as spells

I think so. I wouldn't do that though

You can just store it as a list of spells, and it will spawn the prefab and give you your spell automatically

[queen saffron]

Hi all 😄
I'm doing a VR project that needs manipulation over meshes in runtime, i decided to use ProBuilder plugin for that.
now i'm facing an issue regarding extrude within face normals

it says my face normals are Null

so i computed faces normals once again and tried to add then but..
pbMesh.normals = normals; gives Property or indexer 'ProBuilderMesh.normals' cannot be assigned to -- it is read only ERROR

[main oxide]

my game got modded by an apk how do i prevent this

[knotty sun]

please do not cross post

[clear oriole]

public Vector2Int GetTileGridPosition(Vector2 mousePosition)
    {
        positionOnTheGrid.x = mousePosition.x - rectTransform.position.x;
        positionOnTheGrid.y = rectTransform.position.y - mousePosition.y;

        tileGridPosition.x = (int)(positionOnTheGrid.x / (tileSize * playerUICanvas.scaleFactor));
        tileGridPosition.y = (int)(positionOnTheGrid.y / (tileSize * playerUICanvas.scaleFactor));

        return tileGridPosition;
    }

Found the solution, it was fairly simple, and now i can just pass the raw mousePosition

[spare island]

            // recursively find the root object
            Transform root = transform;
            while (root.parent != null)
            {
                root = root.parent;
            }

            // set the root object to not be destroyed on scene change
            DontDestroyOnLoad(root.gameObject);

is this a dumb way to do this?

i want to force whatever root object the component is attached to be ddol

even if nested

[lean sail]

https://docs.unity3d.com/ScriptReference/Transform-root.html
look at the docs and you can answer this yourself

oh i got confused by the name

[spare island]

is that the same thing?

[lean sail]

you can directly access the root

[spare island]

it says the topmost transform?

i would assume that means the first object in the hierarchy of the scene the component is in not the root object that the component is attached to

[lean sail]

did you read the 2nd line of the 2 lines that were on that page

(This never returns null, if this Transform doesn't have a parent it returns itself.)

[spare island]

yes i did read it i'm just not sure its what i want

if you're saying it is ill try it though

            DontDestroyOnLoad(transform.root.gameObject);

so i can do this?

and that will select the highest object like this

[lean sail]

yes its the same as what you were doing in your while loop

though honestly it seems weird that a child object is doing this logic

[spare island]

well the alternative is putting a script on the HUD where its only purpose is to make it ddol

currently the "HUD" object is just a canvas with no scripts

i tried the line of code, didn't work nvm forgot to recompile

[sly chasm]

sorry how do I make the enemy STOP where it has been hit, instead of sliding to the player thanks :))

code: https://pastebin.com/BCumJBCA

[spare island]

when hit: speed = 0?

im assuming you're using built in unity navmesh and controllers and such

[sly chasm]

yup

[spare island]

for some reason audio random containers do not play on awake if they are instantiated

unity docs says that instantiating is equivalent to duplicating with ctrl + d but thats obviously not the case

[indigo tree]

How are you doing your audio? Prefabs?

[spare island]

audio source attached to notification object that is instantiated

set to play on awake

only plays sound if i drag in or duplicate with ctrl + d

awake must run before the object is instantiated, but if thats the case how does duplicating it work

[somber nacelle]

is the audio resource actually assigned to the prefab or does it get assigned after you instantiate it?

[spare island]

its actually assigned in the prefab

[somber nacelle]

show your code that instantiates it

[indigo tree]

Have you tried making it a prefab?

[spare island]

here is the prefab

both automatic and manual didnt work

[indigo tree]

So are you instantiating that?

[spare island]

yep

let me try with a normal audio clip

[somber nacelle]

show 👏 the 👏 code 👏

[spare island]

the code is Instantiate(prefab) lol

        public void CreateNotification(Notification notification)
        {
            var notifGo = Instantiate(_notificationPrefab, transform);
            var notifText = notifGo.GetComponent<INotificationText>();
            notifText.Set(notification);
        }

for some reason there is a difference between instantiating and using the editor to create a new instance

[somber nacelle]

what does that INotificationText.Set method do

[indigo tree]

Creates the text

[spare island]

nothing related to the audio, but

        public void Set(Notification notification)
        {
            string colorPrefix = "<color=#" + notification.SenderColorHex + ">";
            _text.text = $"• {colorPrefix}<b>{notification.Sender}</color></b>: {notification.Message}";
        }

nothing crazy that should affect how it instantiates

[indigo tree]

🤔

[spare island]

i think this might be a bug actually - here it is with a normal audio clip

gonna check docs on random audio container..

[somber nacelle]

well it's definitely odd that this is happening. one thing you could do that would not only solve this issue, but also reduce your performance impact is to have just one audio source for these and just PlayOneShot on that audio source when you instantiate (or retrieve from a pool so you reduce the number of objects being created/destroyed) the object

[spare island]

well tbh i think theres a way to just play a sound without an audio source but idk how that would work with random containers

[indigo tree]

Maybe. You should probably do AudioSource.play anyways.

[somber nacelle]

but if you can replicate this issue in a blank project then submit a bug report because that behaviour shouldn't be happening

[somber nacelle]

there is not. even the PlayClipAtPoint method (which is static) just instantiates a new AudioSource. just use one AudioSource component and reuse it for all of these notification sounds

[spare island]

"fixed"

[somber nacelle]

and are you actually using .11

[spare island]

sigh no

im using .10f1

im actually being trolled i literally just updated 😭

[somber nacelle]

well then you need to update to get the fix

[spare island]

i guess its better than finding the bug and then it not being fixed yet

[cosmic rain]

That's why you use LTS for solid projects

[somber nacelle]

i mean, bugs can happen in LTS versions too

[spare island]

tbh i've had less problems in the unity 6 preview than i have in LTS

[cosmic rain]

True, but it's more likely to run into a bug in a beta build

[spare island]

i want to see when this update came out

because i quite literally updated less than 24 hours ago

[somber nacelle]

.11 was released on the 17th

Source: https://unity.com/releases/editor/archive

[spare island]

why did it download 10f then..

i went from 2f1 to 10f1

maybe outdated notification? (i downloaded from the update notification in the editor)

[somber nacelle]

because that's the version you selected obviously. if you hadn't restarted the hub between the time the new version was released and the time you updated then perhaps the hub just didn't see the newer version

[spare island]

that might be it i haven't shut down my computer in a couple of days

finally an issue that wasn't a complete skill issue on my part though

[flint dagger]

I'm trying to get the white cube to follow the cursor on the screen but for some reason it's on an offset. Does anyone know how I can make it actually cast from the correct position?

[dusk apex]

Log the input mouse position, camera mouse position result and the actual camera mouse position.

[flint dagger]

Here's an example log. Original mouse pos, mouse pos in the rect on the desktop, and the final hit pos.

[leaden ice]

That should be a viewport point to ray

After converting it to a normalized position

Within the RenderTex

[junior wind]

Is there something wrong with this snippet?
The gameobjects I'm trying to create are being spawned, but they're invisible. The base prefab is showing up appropriately and it's always z = -1 (in 2d), which works for similar prefabs I've made.
I really have no idea why I can't see them

    private void OnDestroy()
    {
        if (currentLife < totalLives)
        {
            Instantiate(iceSpikePrefab, transform.position + topOffset, Quaternion.Euler(0, 0, 35));
            Instantiate(iceSpikePrefab, transform.position + bottomOffset, Quaternion.Euler(0, 0, -35));
            currentLife++;
        }
    }

[leaden ice]

Pause the game and inspect the objects in scene view

Likely they're just either not within view of the camera or just behind something else

[junior wind]

I've tried that. Positions are where they should be, they're just invisible. It's driving me nuts 🤯

[leaden ice]

It's probably behind something then

[flint dagger]

Tried this but it started going really wacky

[leaden ice]

As I said you have to first convert it to a normalized position within the RectTransform

And no that doesn't mean .normalized

It means dividing it by the width/height of the Rect

[flint dagger]

Oh I see

[pine notch]

anyone got a tut for this https://www.youtube.com/watch?v=6PSLfRsN89g
but with OVR stuff

i am trying to add a hand menu like this but in a mixed reality game

[flint dagger]

It follows the mouse again but just like in the first clip I sent it's still at an offset. Idk if I just did it wrong again because I'm dumb tho.

Actually I'm wrong it's offset in a slightly different but more accurate way, not exactly like before.

[digital skiff]

Hello, not sure if this is quite the right place but i think its my best bet?
Im making a mod for a game which reads custom assetbundles and .dlls to allow additional usermade content to be added to it. Im wondering how i can include code from a unity package into a dll to submit to the game? I am able to do it with assemblydefinitions using custom scripts i write myself.

[autumn cedar]

Pretty random but... in variables declaration, do you guys use private keyword with private members or just write them out like.. Obviously there are 2 approaches:

private RigidBody rb; // Clearer

Rigidbody rb; // Concise  

So, what do you guys say is the best convention?

[digital skiff]

ah good news the game doesnt care about package code being included

[west lotus]

I prefer skipping writing out private but we annotate private variables with a _ at the begining so that it is clear it is private anywhere in the class e.g _rb

[autumn cedar]

Ahh yes I know this convention. I used to do that too but stopped for no actual reason. Do you think it's a good habit to do a _? I really want to adapt to set conventions 🫠

[west lotus]

There is no spoon. Conventions exist so that larger teams can work together more efficiently. And each team evolves its conventions over time to best fit them

[autumn cedar]

Hmm got it. Thank you! 😄

[foggy elm]

I used to prefix with the underscore character but it looks pretty ugly, so I now prefix private member variables with m_

[dusk apex]

I'm assuming you meant _ and m_. You'd just use what the team is comfortable with - which may change with every team.

[foggy elm]

Yep

Still haven't found a solution. Does anyone have an idea?

[wicked crystal]

Hello guys, I want to vibrate an object left and right according to its pivot.

[gray mural]

There is the RectTransform.pivot variable

[ebon leaf]

how can i change the pivot point for the default triangle sprite. wont let me edit it in sprite editor cause its within unity and i dont feel like using an actual sprite just to test out an idea but i can see that the pivot is in the center by default however i cant move it

[leaden ice]

Duplicate the default sprite

Edit the copy

[tawdry forge]

Hello, I was wondering while coding if GetComponent() is a costly action or not ? Should I cache the result as much as possible ?

[ebon leaf]

thats actually pretty smart, thx man

[minor patio]

can someone help me with this pls,

void Shoot()
{
    if (HandHolder.childCount == 0) return;
    HandHolder.GetComponentInChildren<HandScript>().Shoot();

    Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
    Vector3 direction = (mousePosition - shootStart.position).normalized;

    RaycastHit2D hit = Physics2D.Raycast(shootStart.position, direction, weaponRange);

    GameObject trail = Instantiate(bulletTrail, shootStart.position, HandHolder.rotation);
    TrailScript tr = trail.GetComponentInChildren<TrailScript>();
    if (hit.collider != null)
    {
        tr.SetEndPos(hit.point);
    }
    else
    {
        Vector3 endPosit = shootStart.position + direction * weaponRange;
        tr.SetEndPos(endPosit);
    }
}

my issue is that it shoots to a certain position, instead of shooting to the mouse position

I first tried making it shoot to it's forward by using shootStart.forward

but it only shot to a certain point (always the same point no matter where I moved

[leaden ice]

It's not really that bad but it's best to cache it when convenient

[gray mural]

My Tilemap is really huge, despite having, as I think, a single Tile. Any way to make it smaller?

[ebon leaf]

it works fine the first time but later on it doesnt wait the full 2 seconds, i can see it throught the editor with serialized field barely switching to -1 for like a milli second instead of waiting properly

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

public class DragonFlame : MonoBehaviour
{
    public float flameTurnOnTimer;
    [SerializeField] float flameDirection = 1;

void Update()
    {
        StartCoroutine(DirectionSwitcher());
    }

IEnumerator DirectionSwitcher()
    {
        yield return new WaitForSeconds(flameTurnOnTimer);
        flameDirection = -1;
        yield return new WaitForSeconds(flameTurnOnTimer);
        flameDirection = 1;
    }

[simple egret]

You start a new coroutine 60 times a second. StartCoroutine will not wait for the previous one to finish!

[knotty sun]

Also WaitForSeconds is framerate dependent

[ebon leaf]

i think i need to use startcoroutine auto in the start method right?

[simple egret]

That's a solution, and you can put a loop in the coroutine method so it runs forever

[ebon leaf]

i want the courotine to repeat

nice, thx man

[rigid island]

fun fact. Start method already has a coroutine

IEnumerator Start()

https://docs.unity3d.com/ScriptReference/MonoBehaviour.Start.html

[ebon leaf]

ok so i started the coroutine in start function like you said and put the code inside directionswitcher in a loop but now its all buggy and doesnt work

im not too good at making loops but the one i made was the classic

for (int i = 0; i < 2; i++) {

}

[simple egret]

I have to go, someone else will take the lead

[ebon leaf]

alr cya

[rigid island]

"its all buggy and doesnt work" is not very descriptive anyway

[knotty sun]

why use a for and not a while ?

[ebon leaf]

its the only loop i know of tbh

[knotty sun]

time to learn

[ebon leaf]

agreed xd

[rigid island]

for(;;)

[swift falcon]

Visual Studio automatically fills in loops on double Tab, its very good

[flint panther]

Why does this happen

[rigid island]

too much coffee?

[flint panther]

                Vector3 handsDirection = other.Hand.position - Hand.position;
                Vector3 gripsDirection = other.grabPoint.position - grabPoint.position;
                float angleAdjustment = Vector3.Angle(root.forward, gripsDirection); // Angle needed to bring it straight0
                Vector3 relativeUp = Vector3.Cross(handsDirection, Hand.right);
                Vector3 targetDir = Quaternion.AngleAxis(angleAdjustment, -Vector3.Cross(root.forward, gripsDirection)) * handsDirection;
                targetRotation = Quaternion.LookRotation(targetDir, relativeUp);```

            (targetRotation * Quaternion.Inverse(grabPoint.rotation)).ToAngleAxis(out float angle, out Vector3 axis);
            rb.angularVelocity = angle * Mathf.Deg2Rad * axis.normalized / Time.deltaTime;```

[flint panther]

Do you know quaternions well?

[rigid island]

just enough to use them in unity

this is however too much math for me this morning lol

[flint panther]

Me too

[flint panther]

Forget the big math. Just this causes the issue too

                Vector3 handsDirection = other.Hand.position - Hand.position;
                targetRotation = Quaternion.LookRotation(handsDirection , Vector3.up);

[rigid island]

why not normalize the direction?

[flint panther]

What would it do

Well, that did not fix it

[rigid island]

idk I normally do it for direction. Idk if matters here prob nont

[flint panther]

It looks like when the rotation goes to a certain point, it tries to do 360 degrees the other way

[rigid island]

Debug values, make sure its not going to 0 vector

[spare island]

Are there issues when invoking events from async functions?

because for the last two days i've had various issues with events just not being invoked correctly

the only thing i can think of is that maybe its because im invoking from inside async stuff

[rigid island]

should not be issue. are you sure that part of the code is reached

[ivory smelt]

Hello, im having an issue that is giving me a headache, my game runs without errors or warnings iside editor, but once I make a build to test a few things, this is what I see when opening the game. Music is playing but as you can see the main menu aint loading and IDK what might be causing it.

Using default render pipeline and a very light project

[knotty sun]

and the target platform of the build is?

[ivory smelt]

Windows

[knotty sun]

ok, so make a Development build and then look at the Player log

[worn ginkgo]

im coding stairs in my game,
for now just going down stairs
essentially if the space between my player and the ground is within a threshold, the player isnt already grounded, and the player isnt trying to jump,
then the player teleports down the distance,
the one issue with this is that the player will always teleport the last little bit at the bottom of a fall,
how do i fix this?

[hexed geode]

Unsure where this goes, but, if I wanna make a Play of the Game system like Overwatch in my game (where after a match, a recording of the best moment in the game plays for all players from the PoV of that player), would the easiest way to do it is to just record an actual video from the PoV of the player and keep it in a buffer or some other way, such as a "demo" like overwatch itself does it

[ivory smelt]

Already tried to solve it yesterday, someone also told me that but i see nothing wrong or idk what am i exactly looking forhttps://hastebin.com/share/yahotojewe.csharp

[worn ginkgo]

thats what i would do,
the alternative is saving the exact animations and positions of every relevant object or player,
which seems like a nightmare and also will likely take up more space than a temporary video file

[knotty sun]

no, YOU look at the player log and look for errors

[hexed geode]

You could record a demo, which, seeing as it's a thing in a lot of popular games, works well and doesn't take up too much space? Gonna have to see how to even make one though

[worn ginkgo]

given you choose to make it so it saves a temporary video to play at the end of the game,
you could also very easily make a clipping system

[ivory smelt]

Ye but i see nothing wrong thats part of the issue, no error logs

Everything seems fine

[knotty sun]

then maybe you should add some, no one but you can say what your game should or should not be doing

[ivory smelt]

Like, putting a Debug.Log() everywhere ?

But whats the point if it works OK inside Editor

[knotty sun]

like putting them where you think it could be going wrong and narrowing it down from there

[ivory smelt]

shoulnd it be some config in project settings or smth?

[knotty sun]

that is what we call debugging

[ivory smelt]

Ikr, but there is literally no place where ir could be failing, I tried removing every scene but the main menu one, which is a simple image with play and quit buttons, and it still fails

[knotty sun]

you do realize that that statement makes absolutely no sense whatsoever

'it can not be going wrong' but 'it is going wrong'

[hexed geode]

Make a new project and try building it

[ivory smelt]

again, what im saying is that it has to be a settings/editor issue since the scene has literally nothing, like 2 buttons and 0 code and it still fails

[ivory smelt]

Dont project settings get stored inside the project folder?

[hexed geode]

Unity asset store apparently has quite a few replay systems to use, some of them even free, which is very handy :)

[ivory smelt]

like, all the project not just the assets

oh wait i misunderstood

[ivory smelt]

oh great is broken too

[hexed geode]

Then it's either your unity install or your pc, I suppose

[ivory smelt]

Bruh I just opened another project and it runs

What is going on

[hexed geode]

Is it a different version of unity

[ivory smelt]

Its different from the original one but the same as this

this one also works and is the same as the original

[spare island]

no that is not what you do

[civic egret]

in unity, how can I make the navmesh agent not pick the shortest path to a destination point? Right now its kinda hugging along the wall until it gets to the point

[spare island]

https://gameprogrammingpatterns.com/command.html
Use the command pattern with all actions in your game, to make a replay you replay the events that lead up to the moment (or save the state at the beginning)

This is the same pattern that is used to make things like "undo" and "redo" functions in applications

To put it simply, you're storing the parameters of a method in an object and then storing that object

so instead of

Move(Vector3 vector, float speed) etc

it'd be more like
Move(MoveCommand command)

obviously, this will require a lot of refactoring if you haven't built your game up to the point to be able to implement this pattern

[hexed geode]

Well, my game doesn't exist yet, and I'll look into this solution if all else fails, such as using a Recorder from the Asset Store, do you think I could just do that? (Assuming it works for a multiplayer game, which it should..?)

[spare island]

well for a multiplayer game you're going to end up using the command pattern anyway for RPCs

or at least you should

also im not sure about the legality of a play of the game system, i believe blizzard has it patented

[hexed geode]

I still don't exactly understand what a command pattern is and what it does, isn't it a bit strange to create an object just for a method? If I'm understanding this correctly

[hexed geode]

Is it just the name or the literal Highlights feature?..

[spare island]

patents are based on how something works

so if your system works too similarly it could infringe (im not a lawyer though and this is not legal advice)

[frozen ridge]

hey guys, i'm interested in behavior trees and i plan to use them for an ecological simulation. What i'm curious about is, will each entity have an instance of the BT?

Let's say i have 50 foxes, will each fox tick its own bt or is there a better way to do it?

[spare island]

ECS

Entity-component systems

Instead of each entity controlling its own behavior, there is one instance that controls all of them - the entities only hold data

at least thats my understanding

[spare island]

you create that object so that you can store the object in an array

so you can then recall those commands

[hexed geode]

Oh, so you can store functions/actions in an array, that makes sense

[frozen ridge]

how can i implement complex behavior with ecs systems

[spare island]

Each entity will need to have a lot of parameters (parameters that you'd already have with per-entity behavior)

[hexed geode]

Wait, so does that mean you literally record what action every player does and then replay it? That's sick

[spare island]

Yes, its how those demos that play on the title screen of some games work

they quite literally just replay inputs

[hexed geode]

Is that how Demos in like, valve games or overwatch work

[spare island]

I dont know how overwatch works but source games have a recording/replay system i believe

[hexed geode]

Also is this in any way useful other than just making recordings of games

[spare island]

where you can replay exactly a player's actions from the console

[spare island]

Well think about how bad for performance constantly recording a video of the game will be

Then think about how you're going to get that video to everyone else

[hexed geode]

True, but having to factor your code in a specific way just for a highlights feature sounds a bit excessive to me

[spare island]

for a game like content warning this is a feasible idea because its such a small scale

[frozen ridge]

command pattern is useful for designer tools as well, like imagine when you do ctrl+z when you want to revert in photoshop/aseprite or whatever

[hexed geode]

Although I suppose you wouldn't need that much factoring?

[spare island]

the only refactoring you need to do is changing the parameters to be an object

which i think can be automated

[hexed geode]

That gives me an idea to implement this into gameplay by having a character reverse time with their ultimate xd

[spare island]

i mean tracer wouldnt work without commands

[hexed geode]

Oh true

[spare island]

well i guess they could just be storing her position 3 seconds ago but idk

[frozen ridge]

yea you could just pop the last few frames command from the array and everything would revert back to let's say 2 sec ago

[spare island]

not only does that allow for highlights, but you can have a full replay system

[hexed geode]

Nono, when you use tracer E, from your PoV you literally traverse on the same path you traversed, it's 100% commands

[spare island]

where you can watch every single thing that happens

[frozen ridge]

for league of legends, i think it uses the commands to literally play the game again if you watch your saved game

[spare island]

yeah i guess so but that could also just be storing the positions of 3 2 1 seconds ago

[hexed geode]

True, true

[spare island]

then interpolating - but i doubt that

from what ive seen while playing tracer it replays very tiny movements

[hexed geode]

Does this mean that quite a lot of games actually use commands?

[spare island]

its one of the fundamental programming patterns so yes

again, read this https://gameprogrammingpatterns.com/command.html

[frozen ridge]

whenever you can rebind your game controls it means command pattern is being used

[hexed geode]

Thank u for telling me :)

[frozen ridge]

that's a wonderful book

[spare island]

it is a very good book and its completely free

[hexed geode]

I'll give it a read, thank u

[spare island]

is this your first multiplayer game

[hexed geode]

Second try, first try at a multiplayer game ended up with me making a Lobby system way after I made a lot of the game, created many game-breaking bugs that I did not have the knowledge to fix so I gave up

[spare island]

I'm working on making some streamlining tools for lobby relay + lobby

[hexed geode]

I'm probably gonna be using photon for this project, do you think I could use any of your tools or anything?

[spare island]

my tools are made specifically for unity services

i'd also recommend against photon from my own experience + their pricing

[hexed geode]

Surely the free version is enough for a small-scale multiplayer shooter?

Are there any better multiplayer solutions for unity

[spare island]

the free tier is for development only

[hexed geode]

Does that mean I can't release games using it?..

[spare island]

once you release you'll need to pay

you have a couple of choices

[hexed geode]

I'll need to look into that then damn, surely this only applies to paid games?

[spare island]

NAT punchtrough,
Relay,
Steamworks are the best options for broke indie devs imo

[spare island]

i'd recommend using either Mirror or Unity Netcode

swear im not being paid to shill unity services

i wish i was i'd love to be paid for anything i do -v-

[worn ginkgo]

how would i get the collision data like shown here?
https://youtu.be/ILVUc_yV24g?si=q-JPxuCLjPPnLUge&t=486

[hexed geode]

Mirror sounds nice, has docs and doesn't intimidate me

[spare island]

Mirror looks nice but I tried to get it to work with relay and it did not like relay

Might work with NAT punchthrough, haven't tried

[hexed geode]

What is Relay?

...or NAT punchthrough

[spare island]

Relay connects players to eachother through a relay, one of the players is a host players and the others are clients

It doesn't require port-forwarding

NAT punchthrough is basically a hacky way to get around port forwarding

sometimes works sometimes doesnt, depends on the network

you may see in some games they talk about your "NAT type"

[hexed geode]

So NAT punchthrough/Relay is what does the connecting and something like Mirror is what makes your code work? I'm sorry I'm pretty new to this

[spare island]

something like Mirror handles the netcode

so how the game works

Relay is the transport layer, which is what gets the connection going basically

[hexed geode]

Ye exactly, makes sense

[spare island]

i've taken a class on networking and got a CISCO certification and i still get intimidated by all the words

I think that relay would be the "Transport" and "Session" layer here
and Mirror handles presentation and you handle the application

this probably is no longer related to code though

well more related to #archived-networking

[hexed geode]

When did you try it? I found a unity discussion page where a unity staff says they didn't add Mirror support yet, and in around December 2023 they added it

[hexed geode]

True xd

[spare island]

When i started on my streamlining project

So about 2 weeks ago

[hexed geode]

Oh damn

[spare island]

Mirror support is iffy

you have to download a random package off of github then take some files out of it, then you have to modify those files because they don't compile, and blah blah blah

the solution they give to connect relay to mirror just straight up didn't work for me when i tried it

so i gave up and used relay and unity netcode* which are in the same ecosystem

[hexed geode]

Would you recommend I use that then?

[spare island]

whats your networking budget

[spare island]

#⚛️┃physics might be able to help?

[hexed geode]

Zero, I guess
This is not a large project I plan to release on Steam or anything, just really wanna make a game for friends and others

[spare island]

relay + unet would be best then

[hexed geode]

Wonderful, thank u

[spare island]

DM me if you need help with it because this is a monster i've been dealing with for the last half month

I'd love to save anybody the time from wrestling with trying to get this stuff to work

[hexed geode]

Thank you a LOT
I'll start working on the project in a few days :3

[flint panther]

...unet?

that is deprecated for like a decade

[fleet gorge]

terrible practice but I used python flask for it once

its really easy to recreate whatever photon does with python flask

but youre using what's supposed to be a rest api to make multiplayer which is bad, terrible

was a fun learning experience but theres a lot of Websocket packages for c#

[oblique spoke]

The transport part maybe, but these networking solutions are doing a bit more than just passing packets around, especially the newer Photon ones.

[thin hollow]

I have a bit of a problem with my AI system.
currently, my system has two components per npc, SensesComponent that's tasking with surveying the world and deciding which NPCs can be seen by this NPC, and AiBrain component, which is tasked with making all the decisions.

I think I remember hearing that classes are always get passed around as instances instead of copies, so I decided to let SensesComponent to store seen NPCs in a List of such class called AITargetObjectReference. It contains reference to the npc object, a couple of other variables, and a variable called freshness that gets increased by the SenseComponent when the NPC is in sight and decreases when it is not - I decided to emulate inertia of senses that way (AI doesn't forget enemy the second it turns around the corner, nor does it notice it instantly when it appears).

now the problem is that when I pass the result of the sensing to AiBrain component - the list contents apparently gets passed as a copy, not as an instance:

// in SensesComponent.cs
        [SerializeField][ReadOnly] internal List<AITargetObjectReference> potentialTargets = new();

...

internal List<AITargetObjectReference> GetSensingResults() => potentialTargets;

It's being received in the Brain component thusly:

//in AiBrain.cs
  private void ObtainTargets()
  {
      if (_sense == null) return;

      List<AITargetObjectReference> localactors = _sense.GetSensingResults();
      listOfEnemies.Clear();
      listOfFears.Clear();
      foreach (AITargetObjectReference target in localactors)
      {
        ...

And the issue I noticed is that targets that are in the AiBrain do not update their freshness, meaning they remain as "seen" indefinitely.
How can this be remedied?

[fleet gorge]

idk most of my work with Photon is just using RPC and Photon View

[fleet gorge]

im pretty sure List has its reference passed rather than a copy. but if push comes to shove you can always use ref, something like

private void ObtainTargets(ref List<AITargetObjectReference);

from there you can call ObtainTargets(GetSensingResults()). doubt this would work though since this is an internal list

[thin hollow]

Should I make it public then, maybe?

[wide terrace]

Is AITargetObjectReference a struct?

[thin hollow]

No, it's a class

I do remember that structs are always get passed around as copies

[wide terrace]

Yeah that's strange. List is class, so it's definitely passed by reference already... Hmm

[wide terrace]

Could you elaborate on the list items' freshness values changing? Everything you've shared is synchronous, and the list is only stored in a local variable within AiBrain.ObtainTargets() - so I don't quite understand how items in the referenced list could be changing values at a time which would impact ObtainTargets()

[thin hollow]

Sure, it's handled in the SensesComponent :

foreach (AITargetObjectReference actor in nearbyActors)
{
    ... // calculations of bools are omitted

    if (inRange && !ignore && inFOV && inLOS)
    {
        if (!potentialTargets.ContainsObject(actor))
        {            
            if (actor.pawnType != EAiTargetType.Player)
            {
                //general case, notice object after a set amount of time has passed
                if (actor.CheckAndIncreaseFreshness(awarenessIncreaseRate))
                {
                    recentlySpottedTargets.Remove(actor);
                    potentialTargets.Add(actor);
                }
            }
            else
            {
                //case for player, awareness acuteness varies according to difficulty
                if (actor.CheckAndIncreaseFreshness(awarenessIncreaseRate * difficultySpike))
                {
                    recentlySpottedTargets.Remove(actor);
                    potentialTargets.Add(actor);
                }
            }
        }
    }
    else
    {
        if (potentialTargets.ContainsObject(actor))
        {
            if (actor.CheckAndReduceFreshness(awarenessDescreaseRate))
            {
                recentlySpottedTargets.Remove(actor);                
                potentialTargets.Remove(actor);
            }
        }
    }
}

The CheckAndReduceFreshness and CheckAndIncreaseFreshness methods modify the freshness of the object in the list (and return a bool).

[chilly surge]

Unrelated to the question, but please make use of guard clauses to reduce nesting.

[thin hollow]

Some of the nesting is indeed probably unnecessary, but I leave it in as it makes the code more readable for me.

[chilly surge]

Are you aware of guard clauses? Instead of:

if (potentialTargets.ContainsObject(actor))
{
    if (actor.CheckAndReduceFreshness(awarenessDescreaseRate))
    {
        recentlySpottedTargets.Remove(actor);                
        potentialTargets.Remove(actor);
    }
}

You could rewrite it into:

if (!potentialTargets.ContainsObject(actor))
    continue;

if (!actor.CheckAndReduceFreshness(awarenessDescreaseRate))
    continue;

recentlySpottedTargets.Remove(actor);                
potentialTargets.Remove(actor);

[wide terrace]

Okay cool 👍

I guess I'm mostly just wondering about the sequencing of these methods. Like ObtainTargets() will always grab a fresh reference to list, and then (presumably) operate upon it immediately and discard the reference. Even if a list was a value type, I don't see how ObtainTargets() could ever be retrieving outdated data. And unless there's some sort of asynchronous code or jobs involved here somewhere, it's not like the items in the list would be changing during a single invocation of ObtainTargets()... You could even verify that it's the same list at any point within ObtainTargets() via a reference equality check - _sense.potentialTargets == localactors.

Where in AiBrain/ObtainTargets() are you expecting to see different values? Is ObtainTargets() invoked regularly? Short of asynchronous shenanigans, the only thing I can think of is ObtainTargets() just not running again after the freshness values have been updated

[thin hollow]

ObtainTargets is runned from the Update() (though I thinking about moving it into Invoke, since it is probably a bit excessive to update targets every frame)
The discrepancy I see is that the AiBrain and SensesComponent run pretty much independantly from each other (the only time Senses call Brain is either when it detects HeardSound event, or decides that something has bumped into the NPC), the AI Brain calls ObtainTargets, and after that decides which target in the list it needs to held as a priority - so the list gets sorted by a variable in the object, and the top result gets assigned to a variable currentAttentionTarget. And when it gets to the said variable - it isn't updating anymore.

Hm... maybe it's the sort function that turns reference list into a copy of a list?

 listOfEnemies.Sort((x, y) => x.importance.CompareTo(y.importance));
 listOfFears.Sort((x, y) => x.importance.CompareTo(y.importance));

Those lists are separate variables in the AiBrain, that have contents added to them from localActors prior to sorting code.

[wide terrace]

Such a puzzle 😅

That arrangement for AiBrain/SensesComponent sounds fine to me 👍

Lists will sort within the same reference - so the act of sorting shouldn't result in a new list...

localactors doesn't get modified within ObtainTargets()'s

      foreach (AITargetObjectReference target in localactors)
      {
        ...

does it?

[flint dagger]

Sorry I brought this up yesterday but I still haven't been able to solve it T_T the white cube is supposed to follow my mouse in the computer but for some reason it's at a weird offset. Does anyone know what could be causing it? This damn thing has taken like 6 hours and I've made no progress.

[thin hollow]

No, the foreach just tests the target and then either skips it, or tosses it into list of fears or list of enemies.

[raven orbit]

how can i make my screen move side to side whenver the player is walking?

i just need a general idea

[wide terrace]

Would you mind posting the AIBrain code on like https://gdl.space/?

[thin hollow]

Sure, but it's almost 2000 lines... Gimme a sec

[flint dagger]

You can just make the camera game object a child of the player. Doesn't require any fancy code.

[raven orbit]

its a child of the player, but i dont think u understood what i meant

whenever the player is moving i want the camera to go left and right if that makes sense

thank you

[spring creek]

Dang. Looked like it doubleposted so I deleted one and it deleted both.
I had suggested moving the camera. Looks like you saw it haha

[raven orbit]

i only saw one it may have been a glitch for you, but still thank you

[mossy valley]

Why can't I see my OnPointerClick function in my Event Trigger -> Pointer Click -> Function?

using UnityEngine;
using UnityEngine.EventSystems;

public class BuildingClickHandler : MonoBehaviour, IPointerClickHandler
{
    public delegate void BuildingClicked(BuildingClickHandler building);
    public static event BuildingClicked OnBuildingClicked;

    public void OnPointerClick(PointerEventData eventData)
    {
        if (OnBuildingClicked != null)
        {
            OnBuildingClicked(this);
        }
    }

    public string buildingName;
}

Changing the PointerEventData to BaseData works

[gray mural]

When having a class, derived from the Editor class, do I have to wrap it with the UNITY_EDITOR conditional, or does Unity ignore it in the build automatically?

[crude mortar]

usually you would put it in an Editor folder so Unity ignores the whole folder https://docs.unity3d.com/Manual/SpecialFolders.html

[next quiver]

i have a script that loops and instantiates an Enemy gameobject of type grenade. What would be the best way to keep track of grenade1, grenade2 and so forth?

[lean sail]

an array/list? this probably begins in #💻┃code-beginner unless you mean something different

[gray mural]

When not willing to put it there, do I wrap it?

[boreal glacier]

Why does Unity struggle to find any input when I use KeyCode

It always throws up the error about the keycode not being found, but the name is always blank when I type the correct keycode in the controls list s

[knotty sun]

Dont use strings

[boreal glacier]

what do I use instead

[knotty sun]

"KeyCode.UpArrow" is not KeyCode.UpArrow

Use KeyCode

[boreal glacier]

ah alright

was wondering because strings worked fine before I wanted to use keycodes

[knotty sun]

yes, but not like that

[boreal glacier]

Also is KeypadEnter the same as the regular enter key? I dont see a non-keypad variant so not sure

[crude mortar]

it couldn't exclude it by default because you can put multiple classes into one file, and you have to include the UnityEditor namespace to use the Editor base class, which would break compilation. You would have to wrap it like you showed above, yes. Also, you could always use an assembly definition (asmdef) to control which code gets compiled to editor / runtime, but if you don't like separating things by folders then I will assume that is a no-go too

[boreal glacier]

nvm

[strange spruce]

im working on an rpg and I'm running into some idea conflicts when working on the player character. The different components of the player (PlayerSkills, PlayerInventory, PlayerStats, etc) usually need access to each other, but manually dragging in each component to another isn't going to scale well. How should I handle this? My first thought is a Player component that just contains references to the components, but feels a bit dirty. Should I just GetComponent whatever I need?

[gray mural]

Do you know whether putting it inside of the UnityEditor namespace also ignores in build?

Or do I still have to use the conditional?

I just don't like that my folder structure is going to collapse when putting all editor scripts into the Editor folder

[boreal glacier]

I mean if you want you could put them all into one script, although that would make calling the individual classes a bit more tedious

[gray mural]

You usually use Singletons for your Manager classes, but those don't seem to be ones

[crude mortar]

It's good to plan around using assembly definitions to organize (which requires separate folders for editor and runtime code) since it speeds up compilation times but also, to answer your question, yes you still have to use the conditional

[boreal glacier]

For stats Ive just been using scriptable objects

[cosmic rain]

Thinking about it abstractly is not gonna help. Take a few real life cases where one of the components needs to access the other one and try to find an underlying pattern that you can use to refactor the setup.

[gray mural]

Got it, thanks a lot!

[cosmic rain]

If you need help brainstorming that, share some of these cases with us.

[boreal glacier]

Oh fuck me theres no more errors and the game crashes

This is gonna be a fun night

[strange spruce]

PlayerSkills is going to need access to PlayerStats to check skill requirements. Your Strength stat (in PlayerStats) sets the max carry weight for PlayerInventory . the specific skills are TBD atm, but I imagine there could easily be one that increases carry weight. Whenever you level you get a point that can either raise a stat or buy a skill, so whatever does the leveling up needs access to both PlayerStats and PlayerSkills.

[cosmic rain]

I see. I wouldn't make these 3 components, but just plain C# classes, and just have them all accessible via the actual component(Character or something). Then each of them can access the other one via the character reference.

[strange spruce]

that sounds good

thanks!

[wraith spear]

Is there a way of checking whether the code is running in a Test Assembly? I would think something like
#if UNITY_EDIT_TEST #endif
Would exist, but I can't find anything like it online / in the official docs. Of course #if UNITY_EDITOR works, but I want the code to run when I play in the editor as well.

[knotty sun]

what do you mean by a Test Assembly? A development build?

[wraith spear]

A separate assembly for Edit Tests

[strange spruce]

so something like this?

[knotty sun]

there you have your define, UNITY_INCLUDE_TESTS

[wraith spear]

I tried that one, but then even in Play Mode the code gets skipped.
My code atm:
#if !UNITY_INCLUDE_TESTS GameState.party.AddAlly(this); #endif

It does work as intended when I make a build

[knotty sun]

your other option is to add your own define constraint into both Tests and normal Playmode

[wraith spear]

Hmmm just including a !UNITY_INCLUDE_TESTS constraint in my scripts assembly doesn't work, I'll look around for some tutorials on the issue

[cosmic rain]

Yeah, except make them properties instead of public fields, and maybe pass the character reference via a constructor or initializer method.

[strange spruce]

awesome

thanks again

when would I call the ctor? OnValidate/Start?

[torn kite]

Hey can someone help me optimise my game

i get randomly 6k batches when looking in a certain area

[strange spruce]

also, why properties instead of public fields? to make the set private?

[lean sail]

thats one reason yes, encapsulation. u can also do logic in the getter/setter if needed

[strange spruce]

true

actually, that's where I can call the ctors lmao.

  public Inventory {
    get {
      if (_inventory == null) {
        _inventory = new CharacterInventory(this);
      }
      return _inventory
    }
  }

[lean sail]

id still initialize them in some method, which would give you a better order of defining things and you wouldnt need to null check everytime something wants the inventory. But doesnt really matter

also looks like youre missing the type there

[strange spruce]

fair

also, it was just a quick mockup lol

[hard estuary]

Mostly to hide the possibility of modifying fields from other scripts. But it also makes editing easier for the future. E.g. you can run some kind of OnChange method to a property, which would be executed every time the variable changes, or add some validation (like _health = Mathf.Clamp (value, 0, _maxHealth)). Without property, you would need to copy-paste the code in every place you modify this variable. But probably in 80-99% cases fields will be more than enough.

what does FixedUpdate do when my game only runs at 45fps? Does it run 45x/sec? Does it change FixedDeltaTime?

[wraith spear]

https://docs.unity3d.com/ScriptReference/MonoBehaviour.FixedUpdate.html
This page explains it better than I can. Short answer, it depends on the frequency of your physics system. The default is 50x per second (or once every 0.02 seconds), and changing your FPS shouldn't interfere with that.
You can look it up at Project Settings > Time > Fixed Timestep

Hi i need assistance in an issue 🙂
I'm creating an object in runtime via ProBuilder Plugin. unfortunately, it doesn't assign the values as it should be. how to fix that?
vertices nor faces are being assigned that i can use later on for extrusion

[cosmic rain]

Are you sure that's how it's supposed to be used? Are you confirming with the docs?

[queen saffron]

https://docs.unity3d.com/Packages/com.unity.probuilder@4.0/api/UnityEngine.ProBuilder.html
yeah i believe so based on this documentary

[cosmic rain]

Can you share the whole !code correctly? It's not quite clear where you create the mesh and where you try to access it.

I've List of vectors 3d preprocessing that would define this polygon as it's positions. while faces are inserted as triangles that processing within the function CreatePolygon in a class Polygon . via ProBuilderMesh component i added them there and created the object by assigning values.
i debugged the code and the do really assign to positions and faces variables of the component. yet, i get withdraw them back from component after processing the mesh

Also, you can presume that activeGameObject is corretly stored in singleton class

Debugging of a simple 4 vertices example

[cosmic rain]

What if you break with the debugger in CreatePolygon at the very end and inspect the proBuilderMesh variable?

I think you're just accessing the wrong object

ProBuilderMesh.Create() creates a new gameObject along with the component. Yet you return a different gameobject.
https://docs.unity3d.com/Packages/com.unity.probuilder@6.0/api/UnityEngine.ProBuilder.ProBuilderMesh.html#UnityEngine_ProBuilder_ProBuilderMesh_Create

[queen saffron]

well it still has the necessary values but upon GameObject return variable it assigns back to Null

[cosmic rain]

Yeah, read my previous message.

That's a different gameobject

Not the one that you assign the vertices and faces to

[queen saffron]

ahh i see

thanks for the assistance @cosmic rain 🙏🏻

Hey, could someone help me with the scrollbar issue I'm getting? I'm changing the content size dynamically through script, and I want the scrollbar to change its size accordingly to the newly changed content size, yet it stays the same size

For reference my initial content size is like 5 pixels wide, and when it expands horizontally,I can scroll everything just fine, yet the scrollbar stays at the size as if the content size is still 5 pixels wide

[thin hollow]

After updating to Unity 2022 from Unity 2019, I now am getting errors in one of my scripts (which was found online and edited) that I used to determine the material the character stands on, to play appropriate footstep sound.
Now it gets this error on meshes:
Not allowed to access triangles/indices on mesh 'Wood_beam_thick_256' (isReadable is false; Read/Write must be enabled in import settings)

Is it possible to get the required data without enabling write on all the meshes in the game, as it sounds a bit unpredictably dangerous for the assets?
The code that generates the error:
https://gdl.space/adisonofex.cs

[cold parrot]

You can toggle that per asset

[hard estuary]

If you don't want to do operations on source files, use .mesh instead of .sharedMesh.
https://docs.unity3d.com/ScriptReference/MeshFilter.html

[leaden solstice]

This code looks really inefficient, you could just use GetIndexStart to see if tri is part of your submesh

[thin hollow]

Yeah but I'll need to toggle it for every asset which player could get on

[thin hollow]

Perhaps, I woudn't know, I didn't wrote like 95% of it

[thin hollow]

Would this work?

            int triangleIdx = hit.triangleIndex;

            int subMeshesNr = m.subMeshCount;

            for (int i = 0; i < subMeshesNr; i++)
            {
                int tr = (int)m.GetIndexStart(i);

                 if (tr <= triangleIdx)
                 {
                         materialIndex = i-1;
                         break;
                    }
                

                if (materialIndex != -1) break;
            }

Hm wait no it wouldn't, I think...

This looks more like it

[leaden solstice]

You'd want to see if triangleIdx * 3 is between m.GetIndexStart(i) and m.GetIndexStart(i) + m.GetIndexCount(i)

If so your material is i-th

[thin hollow]

Oh, thanks!

[thin hollow]

Basically this, right?

if (triangleIdx * 3 > m.GetIndexStart(i) && 
    triangleIdx * 3 < m.GetIndexStart(i) + m.GetIndexCount(i))
    {
        materialIndex = i;
        break;
    }

Alright. I've got a Dissolve Shader Graph that I've set up, and a float property that controls the amount the Shader actually runs on the given object. It's supposed to trigger ingame when you press the spacebar, but it isn't proccing, so I'm not really sure what's going on there.

public class DissolverScript : MonoBehaviour
{
    public float dissolveDuration = 2;
    public float dissolveStrength;

    public void StartDissolver()
    {
        StartCoroutine(dissolver());
    }

    public IEnumerator dissolver()
    {
        float elapsedTime = 0;

        Material dissolveMaterial = GetComponent<Renderer>().material;

        while (elapsedTime < dissolveDuration)
        {
            elapsedTime += Time.deltaTime;

            dissolveStrength = Mathf.Lerp(0, 1, elapsedTime / dissolveDuration);
            dissolveMaterial.SetFloat("_DissolveStrength", dissolveStrength);

            yield return null;
        }

    }

    private void Update()
    {
        if(Input.GetKeyDown(KeyCode.Space))
        {
            StartDissolver();
        }
    }
}```

I just tried a Debug.Log on the last if statement to see if it was even getting the input, and it isn't, so I'm not sure what I'm missing, but that's probably it.

Just don't know how to fix it.

[simple egret]

Take the log out of the if statement so it's ran unconditionally in Update. If you're still not getting it, then your script isn't active, it's on an object that is disabled, or is not attached at all to an object in the scene

[thin hollow]

Double-check the name of the material param, ShaderGraph is often very finnicky with it.
I'd also added a check that dissolve coroutine isn't already running, or else you'll get several competing coroutines

[meager tinsel]

I think might have what I did wrong, depending on my understanding of the stuff. My material is specifically named DissolveMaterial, do I need to put that somewhere in:

Material dissolveMaterial = GetComponent<Renderer>().material;```
Since I was following a tutorial, so I might have just put what they called theirs.

[limpid siren]

Hey guys, i am using unity cloud save
and i am trying to make the player to change his name (playerName)
i want to make a function that check if there is any other player with the name he is trying to change ( CheckAvailability(string name) )

Anyone know how to query in cloud save?

[simple egret]

QueryAsync seems to take two arguments, but you're only providing one.

[limpid siren]

yes, but i can't find any other example with the other param

[simple egret]

Try things, can you construct an empty options with new QueryOptions()? Or maybe it has static members, like QueryOptions.Default? Use VS's completion list at your advantage here

[limpid siren]

https://docs.unity.com/ugs/manual/cloud-save/manual/tutorials/unity-sdk#Query_Player_Data

in this example the queryAsync is only using 1 param

[open bluff]

guys, how can i fix this? looks weird 😕

[simple egret]

This example is out of date, the technical documentation has two params : https://docs.unity3d.com/Packages/com.unity.services.cloudsave@3.2/api/Unity.Services.CloudSave.Internal.IPlayerDataService.html#Unity_Services_CloudSave_Internal_IPlayerDataService_QueryAsync_Unity_Services_CloudSave_Models_Query_Unity_Services_CloudSave_Models_Data_Player_QueryOptions_

[limpid siren]

But there is no example public?

[leaden solstice]

start should be inclusive and start+count should be exclusive, like any other spans

[simple egret]

No, they haven't updated it yet. As I said try things out, the worst that can happen is that you'll get an exception thrown

[limpid siren]

Ye i am trying but it is like 1 out 100 possibilities to hit the correct usage ahah

but thnks anyways s2

ill keep trying ! 🫡

[meager tinsel]

I don't think I attached it. Do I need to put it on the given gameObject I'm using the material in quesiton on?

[simple egret]

Yes of course, if you'd like Update to run, you need to attach it to an active object. It's the same as other scripts

[meager tinsel]

Yep, got it working now! Thank you.

[simple egret]

Mmm I love unchecked parameters leading to "low-level" HTTP errors from the web server
Try passing null as the options? I've seen some examples online where they also use new QueryOptions() but with no apparent issues (or the forum thread don't mention them)

It's a shame that these docs are not kept up to date lol

[crisp minnow]

How to check if a specific component (InputSystemUIInputModule) is loaded somewhere in the game? Using RequireComponent is local to the game object only and of course ended up getting spammed with "multiple event systems present". I'd like to make this check once in the primary active scene manager, but would like it being able to check other scenes (event system would typically be present on a DDOL object, but if I'm running the scene in isolation, I'd want to create it myself as part of debug (will surround whatever logic with #if UNITY_EDITOR)

[somber nacelle]

you could use FindObjectByType

[crisp minnow]

That checks everything?

            var uiInputComponent = FindFirstObjectByType<InputSystemUIInputModule>();
            if (uiInputComponent == null)
            {
                
            }

[somber nacelle]

oop, it's actually FindAnyObjectByType or FindFirstObjectByType not just FindObjectByType, but yes. it will check all actively loaded objects https://docs.unity3d.com/ScriptReference/Object.FindAnyObjectByType.html

[crisp minnow]

That's perfect "This function is faster than Object.FindFirstObjectOfType if you don't need a specific object instance"

And I would just AddComponent if null, then?

[somber nacelle]

yep

[crisp minnow]

🙇

[somber nacelle]

and since UnityEngine.Object has an implicit cast to null, you can just do if(!FindAnyObjectByType<whatever>()) AddComponent<whatever>(); instead of splitting the lines up if you don't need to actually access any of the stuff on the component

[runic pawn]

I have a Vector2 member that i set in my component's Update() called transformVelocity, and I print the value of that out to debug log... Now when I access that same member in my OnTriggerStay2D function it ends up being 0 instead of the value reported in the Update()... is there something about OnTriggerStay2D that would cause this?

here is the code in the Update()

and in the OnTriggerStay2D:

[runic pawn]

and then the log just looks like this:

[somber nacelle]

and are you certain that these logs are coming from the same object? it's also pretty odd that you have exactly one log from update between each log from OnTriggerStay

[runic pawn]

it isn't always exactly one, i guess it just happened to be there for that clip

i mean usually it is, in the case that i'm looking at though

[runic pawn]

yeah i'm certain it's logs from the same object

[somber nacelle]

how have you confirmed that

[runic pawn]

there is only one of these objects that moves

and it only logs, when it moves

[somber nacelle]

that doesn't mean the OnTriggerStay log is coming from that one

[runic pawn]

there is only one object that has an overlap as well

[somber nacelle]

include the name and instance id in your logs to be sure

[runic pawn]

ok

yeah, same thing

my screenshot utility just broke

but i put InstanceID in log and it shows it's the same instance for both prints

[somber nacelle]

ah wait, you only log the velocity when it does move. you need to log when it doesn't move too so you can see that it ends up at 0 before the OnTriggerStay tick

[runic pawn]

the thing is inside OnTriggerStay, the velocity is never non-zero

but i will try logging this all anyway

[somber nacelle]

well you also never see when the velocity becomes zero between those physics updates

[leaden ice]

(transformVelocity.sqrMagnitude > 0.1f)
Debug.Log("tff:" + transformVelocity.sqrMagnitude);

You're only logging when it's greater than 0

[somber nacelle]

if you only ever specifically log it when it is non-zero you won't see when it is actually zero

[runic pawn]

yeah so idk why it goes to 0

it is never set any where else

[somber nacelle]

where in this several hundred lines do you actually move the object

[leaden ice]

Because the object is only moving in FixedUpdate

If it's a Rigidbody

[runic pawn]

it is RB

[leaden ice]

Yeah so

Stop doing physics stuff in Update

That's your lesson for the day

Velocity needs to be measured in FixedUpdate

For that matter why not just grab it from the Rigidbody itself

[runic pawn]

ohh

i tried grabbing velocity from the RB and it's just 0, probably because position is set manually most of the time

i mean position is set based on input

there, finally working. thanks all

I have a movement code that works well, but when I move left and right the sprite flips according to which direction. My sprite is a hook that hooks onto things so I don’t want it to flip. Can someone please help me?

Probably not

Think about it

Or just try them out

that's just multiplying two floats.

my guy, you have a method that you call "Flip". if you don't want the sprite to flip then consider just . . . not using that method

I don’t know how to get rid of it. I tried and then the whole script didn’t work

[somber nacelle]

how about you go actually learn what you are doing instead of blindly copying tutorial code without making an attempt to understand what it does

[midnight brook]

I'm an idiot for not checking that lol

oh ffs I'm adding the vector to the currentSpeed

So both have the same damn sign, so ofc their product is always non-negative

Can someone tell me how to get rid of the flip variable

[somber nacelle]

there is no flip variable

[midnight brook]

...Find where you're flipping the sprite in the code, and then... remove it

It's not a difficult thing, if you know why you wrote the code that you did

[spare island]

sorry to um acktaully you but

there is a flip variable

[somber nacelle]

that's not in their code

i even already told them exactly what they need to do. but allegedly it makes the whole script stop working (it can't)

[devout cloak]

I get an error and I can’t run the game

[midnight brook]

Well, if they're saying they copied code - which it feels like they didn't properly understand - then it's part of the script that causes the flip

[lean sail]

Sounds like someone copy pasted code without learning the basics

[spare island]

so did you look at the error and see what it says

its not just scary red text

[somber nacelle]

that sounds like too much effort for them

[midnight brook]

insert creepypasta of choice here

[spare island]

- something something soul not found .exe

[devout cloak]

I got it. I deleted the whole bottom part last time instead of just the “flip();”

Silly me!

[spare island]

what

[midnight brook]

what

[somber nacelle]

they deleted the Flip method without actually removing the call to that method from their Update method. now that they've actually followed my instructions by removing that method call it works as intended

[lean sail]

You should truly go over c# basics, there are many sites like Microsoft's learn site. You arent gonna struggle your way through a game not knowing the language or how to read a basic error

And plus if you're gonna try insulting people who helped u, u likely arent gonna get future help in here

So gotta learn the basics either way

if you want to use a tilemap, you could have a door layer which has no collision

[lament island]

Anyone able to help with the following question? I'm trying to obtain a method using reflection but that method was sealed somewhere in inheritance. The method obviously still gets called on the base class and I need to invoke the method and have it make calls to deriving methods further down the inheritance line. Is it possible to do such a thing and if so, how would I do it?

[dense sparrow]

i'm attempting to make a model importer, and I have most of it completed. however, i'm having some difficulties processing the armature information. i'm unsure how I should generate bindposes

this is my skeleton generation code

[leaden ice]

If it's sealed there's no such thing as a deriving method for it

[lament island]

I probably explained issue wrong, one moment while I write it up more coherently

[lament island]

I have a method DrawPropertyGUI() which I seal in a class. The class calls a lower down method DrawPropertyGUIWithEvents() which is designed to be the base functionality of DrawPropertyGUI() of the from that point forward. The base class simply calls the overridable method for its functionality along with some housekeeping for the base class. I need to invoke the base functionality of DrawPropertyGUI() externally via reflection and invoke it to draw properties and do housekeeping tasks

[spring creek]

Why via reflection? Also, if DrawPropertyGUI is sealed.... then you simply cannot

[lament island]

I'm making a generic class selector and want to implement the drawing of custom property drawers inside of the class selector

Right now I invoke the DrawPropertyGUI() method from the custom property drawer in order to do this.

[lament island]

I could be missing something obvious. Any ideas?

[leaden ice]

The class calls a lower down method DrawPropertyGUIWithEvents()
What does "lower down" mean here precisely?

I need to invoke the base functionality of DrawPropertyGUI() externally via reflection
If it's sealed that should be very simple. Find the method with refleciton and call it. It cannot be overridden so it cannot be changed.

Not sure what the issue exactly is

are you saying you want to call DrawPropertyGUI without calling DrawPropertyGUIWithEvents()?

If so, that's beyond the limits of what reflection in C# can do for you. it cannot rewrite already written functions.

If you want that to happen, you need to separate the functionality you want into a separate method that doesn't call DrawPropertyGUIWithEvents(), and call that directly.

[lament island]

Lower down meaning in a deriving class

[leaden ice]

well it's presumably defined as a virtual or abstract method in the same class

so it's not actually calling a derived version, it's calling the virtual or abstract method, which gets resolved only at runtime

anyway it's beside the point

[lament island]

Right, because it's just overridden. My bad! So how would I go about executing this via reflection if that's even possible?

[leaden ice]

executing what

[leaden ice]

Can you answer this?

Is this what you want?

For example, you have something like this:

abstract void DrawPropertyGUIWithEvents();

sealed void DrawPropertyGUI() {
  DoSomething();
  DrawPropertyGUIWithEvents();
}``` and you want to do only `DoSomething();` and not `DrawPropertyGUIWithEvents();`?

[lament island]

I want to execute the DrawPropertyGUI for the base class

[leaden ice]

again, what does that mean?

Because DrawPropertyGUI for the base class includes calling DrawPropertyGUIWithEvents() as far as I understand

please correct me if I'm wrong there

See my example just above for what I think you mean

[lament island]

            object customDrawerInstance = Activator.CreateInstance(customPropertyDrawerForType);
            FieldInfo fieldInfo = property.GetFieldInfoAndStaticType(out Type t);
            customPropertyDrawerForType.GetField("m_FieldInfo", BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic).SetValue(customDrawerInstance, fieldInfo);
            objectPropertiesContainer.Add((VisualElement)customPropertyDrawerForType.GetMethod("CreatePropertyGUI").Invoke(customDrawerInstance, new object[] { property }));

So here's whats happening right now

[leaden ice]

that's not an explanation of what's happening right now

This is your code right now, which will very successfully call CreatePropertyGUI

in which case, you have achieved your goal

So I'm trying to understand how your goal differs from just calling CreatePropertyGUI

(you said DrawPropertyGUI above and this code says CreatePropertyGUI so i'm not sure which is right now)

I feel like I asked some pretty simple questions above

If you answer them, it will clear up a lot.

[lament island]

correct

[leaden ice]

ok so... again, your intention is to try to only call part of that function?

[lament island]

No

I just need the base function

so that should work?

[leaden ice]

there is no "base function"

it's sealed

there's only one function

you said it was sealed

therefore there are no derived functions

[lament island]

this is exactly what I'm doing

[leaden ice]

right so then what you want is not possible

What you need to do instead is just call DoSomething(); via reflection. Not DrawPropertyGUI()

(per my example)

[lament island]

I could, but the issue with that is that I wouldn't know the name of the function I'm trying to call if I want to make this generically function for all property drawers

[leaden ice]

If you are making it "generically function for all property drawers" how could you possibly know what their CreatePropertyGUI functions contain?

Maybe you could back up and explain what you're actually trying to achieve here

[lament island]

It will always contain instruction to draw the UI toolkit GUI

[leaden ice]

you're asking an XY problem

[leaden ice]

indeed, but this CreatePropertyGUIWithEvents function is something you created so, it's really unclear what you're asking still

you're asking some very specific question about your attempted solution which for some reason involves reflection

but you haven't explained what you're actually trying to do

[lament island]

The following code attempts to draw the properties in the inspector for a selected type via a dropdown. I currently take in info for an attribute, find all deriving types via reflection in a dropdown menu and let the user select one. Once the user selects a class, I want the drawer to display the drawer found for the type inside the property drawer. If one doesn't exist, it just defaults to drawing all the field for the type

this is why my code is heavily utilizing reflection

hey guys, how can i make an object lock to the cursor? i wanna make a flashlight stick to the cursor the whole time
i have a custom cursor as well currently and a cursor manager and this is the code i have:

`void Start()
{
cursorHotspot = new Vector2(cursorTexture.width / 2, cursorTexture.height / 2);
Cursor.SetCursor(cursorTexture, cursorHotspot, CursorMode.Auto);

flash.transform.position = 

}`

[spare island]

i dont really understand what this error is even saying

what does it mean 'extra field'

there's only one

[cosmic rain]

Sound like you're using conditional compilation and one of the fields is not compiled in the editor.

[spare island]

that cant be right, its probably an editor glitch

[runic pawn]

is it me or does Physics2D.Raycast function only work if you pass in a single layer mask, it doesnt work with combined layermasks?

is that to be expected ?

[cosmic rain]

It should work. Make sure you're using the correct overload of the method.

[runic pawn]

i'm passing in an int in both cases so i don't think its the wrong overload

[cosmic rain]

So in the commented out case it doesn't hit anything at all?

[runic pawn]

well it doesnt hit Stage, thats for sure

[cosmic rain]

Then debug what it does hit.

Perhaps there's an object on the bomb layer that is hit first.

[runic pawn]

it doesnt hit anything as of now, i just never checked it against Bomb

[cosmic rain]

Wdym?

The issue is with the commented code right?

[runic pawn]

right

[cosmic rain]

And when you uncomment it and log what the raycast hits, what does it show?

[runic pawn]

the commented code makes it miss all hits with Stage

[cosmic rain]

A raycast would only hit the first thing in it's way.

If there is an object on the Bomb layer in front, it would only hit that.

[runic pawn]

sec i might see the issue

can i have it get multiple hits using layermasks?

[cosmic rain]

Yea. RaycastAll.

Hello,
I'm currently working on the implementation of the new Input System and I wondered if it was possible to wait for an input in a coroutine?
Here's the code

protected IEnumerator WriteText(string input, Text textHolder, Color textColor, Font textFont, float delay, AudioClip sound, float delayBetweenLine)
{
    textHolder.color = textColor;
    textHolder.font = textFont;

    StartCoroutine(MakeSkippable());

    for (int i = 0; i < input.Length; i++)
    {
        textHolder.text += input[i];
        if (input[i].ToString() != " ")
        {
            SoundManager.Instance.PlaySound(sound, "Sound");
        }

        yield return new WaitForSeconds(delay);
    }

    yield return new WaitUntil(() => OnSkipDialogue());
    Finished = true;
}

The errors:

• CS1662 Cannot convert lambda expression to intended delegate type because some of the return types in the block are not implicitly convertible to the delegate return type
• CS0029 Cannot implicitly convert type 'void' to 'bool'
  Could you help me please?

The OnSkipDialogue function is called when the player presses Enter (keyboard) or Cancel (controller)

[lean sail]

Did you look at the docs for WaitUntil, you need something that returns a bool

You could just store a bool and set it to true in OnSkipDialogue

[tawdry pecan]

I have an system where players can pick up dropped weapons by pressing F. But when the player picks it up, the weapon doesn't go to the hands transform but rather above their head. The weapon is still a child of the hands transform upon pickup. The hands transform works indicated by the rocket launcher. The pistol and the knife doesn't apply

Anyone have any decent tutorials/advice on async/task stuff? I have a saving animation and I want the data to save asyncronously so it doesnt interrupt the animation, not sure where to start. Found some forums but nothing really useable. Thanks! (never touched this stuff before now, this seems like a simple enough problem to get started on)

edit: also I do already have a save/load system I just want to make it async somehow or write a method that asyncly calls my existing save function and waits for it to be done

[cosmic rain]

You can use a coroutine to make it async as well.

[storm wolf]

I can? Currently I am yielding until the save is done and then continuing but it interrupts the animation

[cosmic rain]

Or just some checks in update

[cosmic rain]

What kind of animation? Is the animation related to code?

[storm wolf]

no it is a play on awake function that just moves something across the screen

no code attached

[cosmic rain]

"play on awake function"? So it is a code driven animation?

[storm wolf]

and my save coroutine is literally just this (as pseudocode):

yield waituntil save

yield return startcoroutine(fade screen function)

load next scene

[cosmic rain]

Well, That is "async" technically.

[storm wolf]

no like play on awake is checked I meant so when the scene loads the animation plays until the end of it

[cosmic rain]

If your save is taking a lot of time and is executed on the main thread, there would be a stall obviously

[storm wolf]

that stall is unavoidable?

[cosmic rain]

It is avoidable. But async is not gonna help with it. At least not the way it's normally used in unity.

[storm wolf]

hmm okay what would you suggest?

[cosmic rain]

Use the profiler to see if it's actually a stall

[storm wolf]

okay one sec

how would I be able to tell if its a stall?

for some reason the times are missing but

its 260ms but im missing details?

[lean sail]

can u not expand that to show more?

[cosmic rain]

Is that the spike selected?

[storm wolf]

yes

[storm wolf]

for some reason details are missing on the main window

[cosmic rain]

Scroll the hierarchy view to the right.

[storm wolf]

oh.

lol.

[lean sail]

you can also make the column smaller by dragging the while line near Total to the left

[cosmic rain]

Is that a third party library or something?

[storm wolf]

what do you mean? the SaveGame ?

[cosmic rain]

What does that yield instruction do?

Yes

Can you share the code?

[storm wolf]

yeah one sec

thats the name of my class so

its not an instruction

yield return new WaitUntil(SaveSystem.SaveData);

thats probably the line its worried about

[cosmic rain]

Yes

What's SaveSystem.SaveData?

[storm wolf]

just encrypts and saves the data

the encrypting is what is taking a while ill save you that effort

I can send it if youd like though

[cosmic rain]

Send it.
But if what you're saying is correct, then it's this encryption that you'll need to async or on a background thread.

[storm wolf]

    static string Encrypt(string plaintext, string password)
    {
        byte[] salt = Encoding.UTF8.GetBytes(password);
        byte[] plaintextBytes = Encoding.UTF8.GetBytes(plaintext);
        byte[] key = GenerateKey(password, salt);
        byte[] iv = GenerateIV(password, salt);


        using (Aes encryptor = Aes.Create())
        {
            encryptor.Key = key;
            encryptor.IV = iv;
            using (MemoryStream ms = new MemoryStream())
            {
                using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write))
                {
                    cs.Write(plaintextBytes, 0, plaintextBytes.Length);
                }
                return Convert.ToBase64String(ms.ToArray());
            }
        }
    }

[cosmic rain]

If it's many small operations, you can make it async on the main thread.
If it's one big operation, there's not much you can do aside from running it on a background thread.

[storm wolf]

ahhh

so should I make my save function async then so that I can await the encryption

is that like a standard approach

[cosmic rain]

Share the SaveSystem.SaveData code

[storm wolf]

    public static bool SaveData()
    {
        try
        {
            FileStream stream;
            if (File.Exists(path))
            {
                stream = new(path, FileMode.Open);
            }
            else
            {
                stream = new(path, FileMode.Create);
            }
            BinaryWriter writer = new BinaryWriter(stream);
            PlayerData data = new();
            string textData = JsonUtility.ToJson(data);
            string pk2 = $"{GetCode1()}-{GetCode2()}";

            string encryptedData = Encrypt(textData, pk2);

            writer.Write(encryptedData);
            writer.Dispose();
        }
        catch (Exception)
        {
            return false;
        }
        return true;
    }

[cosmic rain]

Might want to place some profiler markers here to make sure we understand correctly what causes the spike.

[storm wolf]

profiler markers?

you mean like debug so it stops it?

[cosmic rain]

No.
https://docs.unity3d.com/ScriptReference/Unity.Profiling.ProfilerMarker.html

[storm wolf]

ah okay i have not used these before

    static readonly ProfilerMarker s_PreparePerfMarker = new ProfilerMarker("SaveSystem.Save");
    public static bool SaveData()
    {
        try
        {
            s_PreparePerfMarker.Begin();
            FileStream stream;
            if (File.Exists(path))
            {
                stream = new(path, FileMode.Open);
            }
            else
            {
                stream = new(path, FileMode.Create);
            }
            BinaryWriter writer = new BinaryWriter(stream);
            PlayerData data = new();
            string textData = JsonUtility.ToJson(data);
            string pk2 = $"{GetProcessorID()}-{GetMotherboardSerialNumber()}";

            string encryptedData = Encrypt(textData, pk2);

            writer.Write(encryptedData);
            writer.Dispose();
            s_PreparePerfMarker.End();
        }
        catch (Exception)
        {
            return false;
        }
        return true;
    }

am I way off

[cosmic rain]

I think one of the main issues here is that you're executing the whole save logic on the yield instruction. That's definitely gonna botcher unities coroutine execution quite a bit. You should just be checking a simple bool instead. Something like: SaveSystem.SaveComplete.

[cosmic rain]

The profiler marker needs to be inside the method.

Aah

Okay, that's fine.

And place another one in encrypt

[storm wolf]

and then just set that bool at beginning and end of save?

[cosmic rain]

Yes.

[storm wolf]

is that not the same effect as waiting for the save to finish

or you are saying that yielding the method is screwing the coroutine

[lean sail]

is there a reason also you're converting to json, encrypting, then writing as binary? because binary isnt human readable anyways

[cosmic rain]

No, since you're waiting for the whole logic to complete. Even if the logic itself was async(on a background thread), you'll end up waiting for it in the main thread.

[storm wolf]

but its easily convertible

[cosmic rain]

If it was a simple bool check, unity would check for it real quick and continue executing it's player loop. While currently it has to wait for it.

[storm wolf]

ah ok so ur saying async wait for the logic and set the bool when its done

[lean sail]

So is your existing method, as anyone will have access to this code

[storm wolf]

They don't have the password

unless they do some deep digging

[cosmic rain]

I say that wait until should just be checking for a single bool. Not executing a whole method with separate logic. At this point, there's no point in the wait until at all, as it would always return try anyway.

[storm wolf]

looks like it is the encrypt

[storm wolf]

What do you mean by this 2nd sentence

[cosmic rain]

Yeah, and I bet that big part of it is the GC.

[chilly surge]

The entire SaveData method is executed synchronously.

Putting it in a coroutine doesn't magically make something asynchronous.

[cosmic rain]

Wait until is called by unity every frame to see if the coroutine can be resumed. If it returns true, it resumes the coroutine, otherwise checks again on the next frame.

What you have now is that it executes the save method entirely instead of checking a variable. This would mean that unity can't move on to executing other code until the save method returns.

Obviously that's only part of the problem, but it's still something you should consider refactoring.

[storm wolf]

ok I'll turn that into a bool now, and then should there also be internal async methods in the save system

[cosmic rain]

I'd start from getting rid of the GC overhead.

You can create the arrays and other data structures on game start in your SaveGame class. Then reuse these arrays instead of creating and destroying new ones on each save.

[lean sail]

I'd truly just get rid of the encryption and move on if it works as fast as you want. Though not sure how much of a "encryption wont matter locally" talk I wanna go through

[storm wolf]

its a static class 😢

[cosmic rain]

Doesn't really change anything.

[storm wolf]

if they get the password they deserve it lol

[cosmic rain]

You can have a static constructor or some kind of initialization function where you do that

[storm wolf]

oh yeah...

[chilly surge]

Idk if JsonUtility or your PlayerData is thread safe or not, but you can just do that part on the main thread and move everything else to a different thread and that will be all.

Don't need to change much else.

[lean sail]

Same could be said about anyone who actually decides to convert from binary to json, and then back. Trust me when I say if the password is local then they already have it. Itll just be a minor headache for the person who writes an app to modify save files if your game gets popular enough

[storm wolf]

yeah but i would rather it be a mediocre headache than a minor one, binary is way too easy I would rather encode and encrypt

[chilly surge]

If it's a single player game, who cares if the player is cheating; if it's a multiplayer game, you can't protect it this way regardless.

[cosmic rain]

That would probably be a simpler solution, but I wonder if it's actually not as slow as we think and the main issue is garbage collector.

[chilly surge]

I doubt GC kicks in in that exact profiler frame to be the issue.

Not sure how saving is used in their game, but usually allocation is only a big concern in reoccurring operations, so things that are called every frame or every fixed amount of time, if GC can't keep up with your allocation then it has no choice but to pause the world to do clean up. In one off operations, allocation is generally fine, and presumably saving isn't performed all the time.

[storm wolf]

ok I improved it, visibly less buffer, still a tiny kick though

    static string _password = null;
    static byte[] key = null;
    static byte[] iv = null;
    static byte[] salt = null;
    static void Init()
    {
        _password = $"{Code()}-{Code1()}";
        salt = Encoding.UTF8.GetBytes(_password);
        key = GenerateKey(_password, salt);
        iv = GenerateIV(_password, salt);
    }

this is whats left of the save function:

    public static bool SaveData()
    {
        try
        {
            SaveComplete = false;
            FileStream stream;
            if (File.Exists(path))
            {
                stream = new(path, FileMode.Open);
            }
            else
            {
                stream = new(path, FileMode.Create);
            }
            BinaryWriter writer = new BinaryWriter(stream);

            PlayerData data = new();
            string textData = JsonUtility.ToJson(data);
            string encryptedData = Encrypt(textData);


            writer.Write(encryptedData);
            writer.Dispose();
            SaveComplete = true;
        }
        catch (Exception)
        {
            return false;
        }
        return true;
    }

SaveSystem.Init();

SaveSystem.SaveData();

yield return new WaitUntil(() => SaveSystem.SaveComplete);

not sure if this is what you meant?

[lean sail]

this would still run all at once, when you call SaveData

[storm wolf]

how do you mean

[lean sail]

all your logic is still running on the main thread, when you call a method it will run to completion

[full canopy]

using System.Collections.Generic;

    }
}```
compilation error: ```'Component' does not contain a definition for 'link' and no accessible extension method 'link' accepting a first argument of type 'Component' could be found (are you missing a using directive or an assembly reference?)```
how would I get link to return linkedcomponents link if the linked component is a linked component?
(i hope that made sense)
i could obviously just getcomponent, but if there's multiple how do i ensure that its the correct one?

[storm wolf]

ah I need to make it async? I am not very familiar with making/using other threads

[spring basin]

Hey, Im trying to add ads to my UWP unity game. I came across this provider called AdsJumbo. But they seem to have only native cpp support. So how do I call methods like ShowInterstitial and ShowReward from within the unity C# script to the external native code?

[lean sail]

you could look into multithreading but its not something id truly recommend if u arent good with it already

[storm wolf]

:/ is that the only option or would using a Coroutine work here

[lean sail]

looks like u just need to do this
if (linkedComponent is LinkedComponent linked)
then you can access it

[cosmic rain]

I'd say that 6MB of GC is quite a lot. As for the GC timing, we don't know for sure. It might be happening right on the spot.

[cosmic rain]

Profile it again.

[lean sail]

coroutines run on the main thread, so no it wouldnt work. Multithreading is your only option if you want multithreading

[full canopy]

thanks, did not know you could do that before

[storm wolf]

its the init 😭

this sucks

[cosmic rain]

Why is it called during the save..?

[storm wolf]

OHW AIT

ur right lmaooo

im so stupid

[west lotus]

Putting the entire encryption process on a background thread would be rather easy. I do not think that the encryption algo itself is parallizable.

Why does your init generate 6mb of garbage ?

[cosmic rain]

Well, from what we can see, the save itself, including the encryption is just 3 ms. The issues was the GC.

[lean sail]

it does seem like a lot, especially since encryption is made to be quick. It could also be from that _password thing which is 2 method calls and string interpolation

[cosmic rain]

Yeah, Code() and Code1() are sus as well.

[storm wolf]

moving the init nulled it out or at least like 95% of it but I can't notice it and the editorloop takes longer than the save now so thats a win

[storm wolf]

sus but not performance intensive

Thank you @cosmic rain and @lean sail for the help appreciate it seriously +1 rep for you both
