any method that calls itself

[regal olive]

so like this? ```cs
private i = 0
private max = 10

void Awake() {
function(max)
}

void function(int _max) {
if(i < _max) {
i++;
function(max);
}
}

[urban warren]

Exactly

[undone coral]

your game looks nice

[compact ingot]

dual contouring for mincraft style terrain makes no sense

then its not minecraft style

sharp features in DC are just estimations based on the neighboring voxels, they arent necessarily accurate to what the SDF formula can express, CD is still bound by the sampling resolution

sure, you can make it work

but a full DC implementation is actually quite heavy (computationally)... i'd actually not use it if performance is a concern

how big are your cells/chunks?

and have you parallelized it in any way?

ok

you'll probably also run into performance issues with the SDF sampling if it uses many geometric shapes

so those may need some optimization so you don't sample all of them all the time

[kind sigil]

Editor scripting. I need to be able to look up a given instantiated GO and retrieve the Prefab asset that was used to prefabricate that GO. Is there API utility for this, if so, let me know.

[wind badge]

Never tried this specifically but I'd look in the AssetDatabase docs

[misty glade]

K so this might not be a code specific question, but... I've recently set my app up to automatically create a new account if a user connects with an unknown device ID. The app requires user input ("tap to login") to do so.. However, since I deployed this morning (internal track only) to google play, I've had several new accounts created. Does anyone know if google does some sort of automated device testing against private apps? I have some limited user metrics, they all come from a 10.240.. IP (I don't know if that's helpful) and have a variety of device types/OS

[fickle inlet]

Hey, I am writing an announcer/messenger that notifies players on events in the game. I'd like to find some resources on best practices and design patterns? I have written mine but I am not satisfied, i'd rather read about similar topic and do it the right way

[sly grove]

I'd look into the observer pattern, and an event bus/queue kind of system

At the simplest - all you need is a queue of Notification objects, and then an object that is always pulling Notifications from the queue and displaying them one by one. The notifications can be "pulled" as in "check constantly for new notifications", or it can be a push/event system (which is where the observer pattern comes into play)

[undone coral]

there's a possibility they have automated testing, and this is the origin of what you're seeing. the private ip address range there is pretty idiosyncratic

whose login system is this? all yours from scratch?

[misty glade]

yeah, it's uh.. actually an azure IP since.. duh, it's behind azure perimeter stuff

yeah

(mine - from scratch)

i originally had a pretty robust username & password thing with tokens, hashcash and salted & hashed passwords, and my designer told me it's all not necessary, we'll just use device ID to track users so there's no forgot password or 'play your account on another device' needed

which sort of sucks because that effort was a good week

3/4 of the way through this article https://docs.microsoft.com/en-us/azure/architecture/example-scenario/gateway/firewall-application-gateway#application-gateway-before-firewall and I'm sort of giving up on keeping tabs on a client's IP

[undone coral]

lol

it's okay

i think hashcash lost out because decoupling your login API from the rest of your backend has other advantages, besides managing DDoS better

also your designer is right

[undone coral]

you can see that the firewall source nats traffic, which is why you don't see the client's ip

this is puzzling to me

imo, it shouldn't source nat since it's coming from the WAN

[real ivy]

guys, could someone experienced with API calls gimme like 5 mins of his time

I need some guidance and got some questions, I would highly appreciate it

[chilly sun]

Please define “API calls” further.

[real ivy]

simply put, I am trying to use some Google Play store functions/methods, but I am unable to simply read or find more about it

such as this,
https://developers.google.com/games/services/common/concepts/leaderboards

here they mention methods such as ( Social.ReportScore() ) <-- this I found in a youtube Tutorial
but that's the only thing they mention, I want to read more about the Social class, where does one find these ? I understand the easiest asnwer would be to just keep looking , but honestly I feel lost here and am not able to find it

I need some guidance here with it

in addition to that

they use this weird syntax

Social.ReportScore(12345, "Cfji293fjsie_QA", (bool success) => {
        // handle success or failure
    });

where there is** =>** , what's this syntax called ?

[austere jewel]

Lambda function

Not knowing basic language features doesn't feel very #archived-code-advanced, I would continue in #archived-code-general

[real ivy]

[winged mirage]

So, guys, I'm trying to make an enemy ai. According to my logic, it shouldve worked just fine, but the enemy just stays at its own position : /
https://paste.ofcode.org/rMsE4VCdEnhYPexdt2aymZ

and this is another piece of code, similar to it
https://paste.ofcode.org/t6sHS8PRdTdWpfMWZNBG32
but the problem here is :It doesnt stop patrolling when attacking the player. Basically, it looks at the player, attacks once, and then again it starts patrolling

Now, I've been working at it for 2 days straight, still couldnt find any solution : /

[pulsar raven]

@winged mirage I used to write the state of the NPCs on a object so I could read it in the scene, I suggest you to see some guides about state machines and rewrite the code firing NPC functions. You are also firing raycast on update which is not that convenient. I don't know how your game is made and I just read the code briefly, what kind of bullet are you spawning? Is the bullet occluding the raycast to the player?

[winged mirage]

the bullet is fired from the attackpoint of the enemy to the forward direction when the raycast hits the player

umm, if it seems complicated, can i send you the whole project instead ?

[winged mirage]

it's the closest i could get to my goal. All it needs is to wait when attacking, instead of patrolling immediately after that.

[pulsar raven]

No, if it's not working rewrite it, test every function singularly, then work on the state machine your NPCs need. I used to control Coroutines by starting and stopping them accordingly (Usually 1 coroutine at a time). In the update function i just kept the movement interpolations.

[winged mirage]

I did use LookAt, while raycasting during Chaseplayer and attackplayer function, so, the enemy wouldnt patrol unless the player either goes out of range, or behind a wall

k imma get some debug.logs workin

[pulsar raven]

The routine would contain the action itself and run a function to get the action state (enemy near, occluded, ecc), if the action state would be different the routine would shut down and start the next one.

[upbeat path]

why don't you use the VS debugging system and just step through your code?

[pulsar raven]

that's a good feature ❤️ used to make the most weird DrawOnGizmo graphs before knowing about it

[upbeat path]

Anyone who doesn't use it is, imo, a complete idiot

[winged mirage]

shut

[pulsar raven]

Anyways I came here with a question too.
Has someone had experiences with Kotlin in Unity?
I have to hack myself trough an AR headset to grab the accelerometer data, sadly their Unity SDK doesn't reflect the whole API so I will have to implement a little part of their SDK in unity on my own.
The libraries used are in Maven (and I would like to know how to load them) - I had to add them to the baseProjectTemplate.grade to run their SDK is that enough.
I have to admit I don't really now anything about this kind of implementations nor how to debug them - I have highlighting only rn.

let's say I have this in my kt file

//these are in Maven
import androidx.lifecycle.MutableLiveData
import com.company.library.deviceClass
import com.company.library.deviceClassListener

class GetAccelerometer(
    val accelerometerData: MutableLiveData<FloatArray> = MutableLiveData()
) {
   init { 
          deviceClass.getInstance()?.setDeviceClassListener(object : DeviceClassListener {
          override fun OnAccelerometerEvent(p0: long, p1: FloatArray?) { accelerometerData.postValue(p1?) }
          )
        }
    }

In Unity I'd write

using System.Collections;
using UnityEngine;

public class GetJavaAccelerometer : MonoBehaviour {

    AndroidJavaObject  accelerometerObject;
    float[] accelerometerData;

    void Start()
    {
        accelerometerObject = new AndroidJavaObject("com.unity3d.player.UnityPlayer.GetAccelerometer");
    }

    void Update()
    {
        accelerometerData = accelerometerObject .Get<float[]>("accelerometerData")
    }
}

I am concerned about the "com.unity3d.player.UnityPlayer.GetAccelerometer" part and anyways if this is ever going to compile

[pulsar raven]

So it's not importing anything from Maven, getting big gradle compilation errors. I wish I could read the code from the sdk but that's in a dll

[remote drift]

Any idea internally you can add extension to async handles?
Basically if my game has it's own tick system and I would want to do TickDelay, is there any special options for it, or is it as simple as comparing finishTick == curTick? (which will be checked every frame by game)

[peak parcel]

So I have an audiosource that is the output of Dissonance for the voice chat of my game. I want to output the output of this audio source to a different audio source that manages the character lip synching and make it play the exact same thing. I have a reference to both audio sources. How would I make this possible?

    AudioSource audioSource;
    [System.NonSerialized] public AudioSource speakerAudioSource; // The audio source that the instructor outputs and is fed into this script to manage the lip synch

    void Start()
    {
        audioSource = GetComponent<AudioSource>();
    }

    void Update()
    {
        audioSource.clip = speakerAudioSource.GetOutputData;
    }

[alpine adder]

hey all do you have any recommendations for good resources when it comes to memory management? I just did a round of interviews and they went into a deep dive with structs vs classes in vs out the dispose classes and calls and serialization

[compact ingot]

this is a rather vast subject, most people would deal with it by understanding the fundamentals of memory and how a program is executed

[upbeat path]

Just read the Microsoft C# docs, they give you all the info you need

[calm ocean]

    public abstract class RuntimeSet<T> : ScriptableObject
    {
        public HashSet<T> Items = new HashSet<T>();
    }

Suppose I wanted to turn a hash set into a scriptable object, and I wanted to be able to perform hash set methods on this class, would it be possible? Like

RuntimeSet<Integer> set0 = new RuntimeSet<Integer>();
set0.Add(0);

I know I could also just do set0.Items.Add(0), but I was wondering if it's possible to not have the .Items. in the middle.

[plucky laurel]

you can implement the interface

ICollection<T>

[compact ingot]

implement ISet<T> by redirecting all methods to your Items

[calm ocean]

Ok thanks

Is there a way to instantiate a prefab and initialize a custom script that has an initialize method in one line? Say, for example, I got a "Human" prefab, that has a "Human" script. The script has an Initialize method that takes in a height and weight. Instead of doing:

GameObject newHuman = Instantiate(humanPrefab);
newHuman.GetComponent<Human>().Initialize(humanHeight, humanWeight);

I can do them both in one line?

I was thinking maybe give the Human script a static method that instantiates the prefab and does the initialization, and I would use this static method to do both steps in one. Thoughts?

[upbeat path]

What would be the benefit of this?

[calm ocean]

I noticed that my code has a lot of these Instantiate and Initialize, I was wondering if there was a way to clean that up

[upbeat path]

the end result in IL is the same. It just makes your code harder to read and debug when you concatenate lines

[plucky laurel]

yes you can write extension methods that do that
example of what i do

var obj = prefab.Clone<Script>().Init(this).Attach(transform);

[calm ocean]

Where does this line go?

[plucky laurel]

its an example line

Clone and Attach are extension methods

[calm ocean]

What does prefab.Clone<Script>() do?

[plucky laurel]

same as Instantiate

naming choose yourself, it can be Instantiate

[obtuse remnant]

Know what causes allocation, about boxing, and how to use span and pooling.
Know what goes on the stack vs the heap.
That should cover you for most deep dives.

[plucky laurel]

var obj = prefab.Instantiate<Script>().Initialize(this).SetParent(transform);

clearer example

[upbeat path]

And when you get a null reference exception how do you debug it?

[plucky laurel]

same way you debug anything

[upbeat path]

but you cannot step that code

[plucky laurel]

fine with me, those are rarely the places it throws

[upbeat path]

fine with you, you know what you are doing. Not so fine with people who do not

[calm ocean]

Why do I have to pass in this into Initialize()?

[upbeat path]

see what I mean?

[plucky laurel]

yeap

[upbeat path]

and this is code-advanced

[plucky laurel]

its best you dont do that

[calm ocean]

Don't pass in this or don't do the whole thing?

[plucky laurel]

like in general, wait before doing such things, you will shoot yourself in the foot

dont do the whole thing

[calm ocean]

Okay, thanks for the help anyway

[plucky laurel]

master the "standard" way of doing everything first

[calm ocean]

I currently have a valid way of doing things, I came here to ask if there was a better way, but if there isn't, then I will just stick to what I am doing.

[plucky laurel]

"valid" is relative, contextual, so the question is vague

same with "better"

in your case i deem that it is better to stick to standard ways

[upbeat path]

there is not a 'better way' there is a more source code efficient way. But you need to be very proficient before you try to use it

at the end of the day the executable code will be almost identical and that is what matters

[undone coral]

there are a few approaches to creating android plugins

there's nothing special about kotlin versus java here

The libraries used are in Maven
so what do you really mean by that? are you saying they are on a website called maven.com ?

you might be confused because there's maven the build tool versus maven the package repository

your build tool is gradle, not maven. you'll have to add a reference to the package you are trying to use into gradle. this will look something like

dependencies {
 implementation "com.google:androidx.accelerometers:1.0.5"
}

@pulsar raven is that helpful?

the best way to set up a plugin for development in unity is an android library plugin

you should open andrtoid studio, create an android library project in a directory inside the assets folder, add an android .gitignore to this directory, and work out of that

hope that helps

[errant steppe]

hey guys, can someone help me out how to make sucha system for pouring sauce using particle effects? (It'd be on the UI) https://youtu.be/5xPO7BBU94g?t=380
we can either discuss in a thread or DMs, thank you!!
the issue I have with it right now is if it goes too fast, it glitches through collision that's supposed to keep the sauce on top of the food, but primarily, the particles also start to disappear after some seconds - the max particle count and the lifetime are set to the highest values, though
also the particles have colliders, but collision shouldn't remove any lifetime either as I set the related properties not to do so

[undone coral]

this is a really great effect

[errant steppe]

yeah it's amazing. I'm creating a similar game right now but am stuck on how to approach that properly - I'm guessing it's either particle systems or shaders somehow

[undone coral]

this doesn't use physics collisions. they are tweening a sprite they spawn to a randomly selected y point

[errant steppe]

but wouldnt you need like craptons of sprites for that?

[undone coral]

it's always individual sprites. the relish effect uses the sprites as a mask for the pickle texture, and also has an outline renderer over the mask

[errant steppe]

pickle?

[undone coral]

sorry i meant relish, early in the example

[errant steppe]

oh gotcha

[undone coral]

the mustard effect is the most sophisticated imo - it looks like they are spawning a sprite that is a line segment

[errant steppe]

yeah the mustard is what I want to figure out

I can code the pouring of other stuff

[undone coral]

or many individual small sprites

seems most likely

[errant steppe]

that'd be extremely inefficient imo

[undone coral]

i think you are making a lot of assumptions about performance that are inaccurate

[errant steppe]

like 100+ game objects for a full line sound a lot to me

I mean, it could be simplified though, but it'd take more objects the more precise I want the line to be I presume

[undone coral]

let me illustrate for you

https://player.appmana.com/watch/wendysbasketball - this is a minigame i made in march. try shooting a basketball into the seats

how many seats do you think there are? each of them has a rigidbody

[errant steppe]

I mean my entire scene has <50 game objects lol

[regal olive]

hey can i have some help with unity Lmao

[errant steppe]

so like, in comparison to that I mean it sounds a lot

[undone coral]

did you open the link

[errant steppe]

its loading

cant load it

anyway so as I said, compared to my current scene structure and collider usage (which's closely equal to 0), it's tons. but if we move on with that idea, I guess I'd need to check where a particle lands on the food and spawn a small sprite there, right? and perhaps give it collision so that the sauce can stack up

[undone coral]

my bad, try it again

it's important just so you can take a guess

[errant steppe]

woah yeah

I was hoping there'd be a convenient workaround using particle systems. I had individual sprite spawning on mind but wasn't sure whether I should go for it, for the that reason lol

but then imma try it with the good ol' horse sense, thank you!

[undone coral]

well

you haven't guessed yet

@errant steppe there are like 1,200 rigidbodies back there, with as many as 100 that wake up

[errant steppe]

holy heck

[undone coral]

and this is hdrp

[errant steppe]

I mean of course, unity can handle it, but it felt weird the way I had in mind is actually the approach taken lol

[undone coral]

you can still use a particle effect but i think it is redundant

well

i don't think there are rigidbodies on these spirtes

in the game you showed me

[errant steppe]

I can't because of the issue I mentioned and it's really buggy with collision

[undone coral]

it isn't using physics

it's just tweening into position with an accelerating curve

an d the position is sort of faking the collision

the build up

[errant steppe]

oh youre right, I can simply increase the Y of them

yeah

I'm curious how that'll look, I appreciate the enlightenment haha

[undone coral]

this is also easy to do with the particle effect

but you'd have to know shuriken well

[errant steppe]

I dont really know about that so gonna do the horse sense approach

[undone coral]

as long as you have gpu instancing enabled on your sprite material (if you're using the default one, it is not), it is unlikely you will run into a performance issue showing many sprites

[errant steppe]

oh, that sounds like a huge benefit to have, didnt know thats a feature

thanks a lot!

[final dirge]

has anyone managed to make VSCode work with Unity debugger? It's currently deprecated and I can't seem to find a way to make it work

[hoary pendant]

There are currently no plans to keep that project maintained, so only VS and Rider are supported with Unity debuggers at the moment. Maybe someone forked the project?

[buoyant vine]

community dropped support for it

so its ded

vscommunity or rider or configuration hell

[final dirge]

Ah! So I there is no way to debug in vs code currently?

[buoyant vine]

no and it wont be in future

as long as community stoped it

and they dropped it this year

[hoary pendant]

Not easily, you would have to attach your own debugger to the symbol information, but that's extremely unsupported and possibly buggy

[buoyant vine]

so doubt they pick it up this year again

[final dirge]

well that's unfortunate haha

[buoyant vine]

vscode has problems in itself

why it wont be as functional as rider or vscommunity

you can import in rider your vscode settings tho

[final dirge]

yeah I tried rider but I really don't like it

[nocturne tusk]

vscode is a text editor

[final dirge]

I've been using VSCommunity for years and I wanted to try and change to vscode because it's lighter

[buoyant vine]

vs 2022 is as fast as vscode

[nocturne tusk]

they are probably on MacOS

wait maybe not (idk no nvm)

[final dirge]

I have 2022 and it's def not as fast, although quite close to it

[buoyant vine]

well yes

doing nothing is always faster than doing something..

[final dirge]

haha

[nocturne tusk]

rider is the superior option if you do not mind the price tag

[buoyant vine]

i dont even use riders ful functinoality... most functionality i use in rider is my own live templates

[final dirge]

I've seen lots of people swear by rider but there's too much stuff I don't use

[buoyant vine]

mee too lol

[final dirge]

I just want snippets and intellisense

[buoyant vine]

yes then only use those?

snippets are called live templates in rider

pretty easy to setup

and intellisense works out of the box

[final dirge]

yeah but if I don't use anything else there's no point for me to use rider instead of vscommunity haha

[buoyant vine]

community has no live templates

i use intellij and rider so ... i know all shortcuts and so forth.. even when i dont use ful potential

[final dirge]

It does I have snippets on vs community

[nocturne tusk]

Do you not use the debugger in VS?

[buoyant vine]

these are custom snippets.. not the snippets microsoft thought you need... the snippets you created

[final dirge]

aah yes

I don't I usually just print stuff since that's what I was used to haha

[nocturne tusk]

hmm yeah that's good for small projects but when the project gets large recompiling and running takes a while

[final dirge]

yeah that's why I need to start building that habit haha

[buoyant vine]

just make proper assembly definitions...

[undone coral]

this might be a really stupid question

but is there a way to mark a game object as static with respect to some parent hierarchy?

for example, if i have a vehicle model, the model is static with respect to the vehicle's transform root, which would help a lot with shadows

[sly grove]

only if said parent hierarchy happens to be a whole scene

[undone coral]

fudge

[worldly stratus]

Not sure if this is the right section but I have no friends so ill ask here, its more of a math problem and im not doing this in unity but anyway...

I have a "snake" on a plane at 0,0,0 and a bird at 10,10,10 so the distance is roughly 17.3 points. the snake can only eat the bird within 15 points so I need to move the X and Z up to 10 points towards that bird.
I cant seem to recall or find the math to do this

[regal olive]

I am using ummorpg and trying to disable this component

GetComponent<CharacterController2k>().enabled = false;
// set new position
transform.position = destination;
GetComponent<CharacterController2k>().enabled = true;

I think it's not finding the cc

[orchid cedar]

Does Application.onBeforeRender execute before the awake method on other scripts? I am unable to find much information about it online.

I'm trying to disable certain scripts in my scene on runtime but I'm not sure how to make sure a script execute prior to an Application.onBeforeRender callback would run. It appears script execution order makes no difference

[undone coral]

Does Application.onBeforeRender execute before the awake method on other scripts? I am unable to find much information about it online.
no

onBeforeRender is called before the render loop (i.e., before something like camera.render is called on every camera)

that family of callbacks (i.e., a "subsystem") happens very nearly after the last late update (i.e., after WaitForEndOfFrame)

[orchid cedar]

Thanks, a forum post said the opposite and I thought it was wrong. Is there anything that could cause a script to run before it's disabled in an awake method?

[undone coral]

can you link me to that forum post

what is your objective?

the best way to add specifically timed stuff is using the PlayerLoop class

the most confusing and poorly documented part about unity's internals is how the main thread and the render thread interact throughout the duration of all the player loop subsystems, i.e. collections of methods (like Update) that are all called in groups, one after another

[undone coral]

it's weird that the docs are talking about vr inputs

it is true there is a subsystem specifically for the XR input system to update the transforms of objects tracking 3d positions, and it is right before the render loop

you are best off breaking on the getcurrentplayerloop() method's return and exploring the structure that is returned. it was very helpful to me

[orchid cedar]

https://forums.oculusvr.com/t5/Unity-VR-Development/Photon-PUN-2-Camera-freezes-in-the-Oculus-Quest-when-second/td-p/870964
The post in question is the first reply, although I think this may be me misunderstanding how the subscription to Application.onBeforeRender works

I've been trying to de-couple the initialization of an OVR camera rig from instancing a new version of my player prefab, for a multiplayer application. The camera gets initialized before any script can seemingly disable it but I may also be misunderstanding how Unity initializes a camera for stereoscopic rendering
Unity breaks seems to break the VR rendered view when there is more than one active camera in the scene

I've tried disabling the parent game object in an awake script of a parent of that object, and even moving that script to the top of the script execution order, to no avail. I've also tried keeping all components disabled, then enabling the relevant components as needed, but this seems to make no difference. I thought the issue would be because of the subscription to Application.onBeforeRender but since that executes on the back of the render thread it's definitely happening after the aforementioned awake script, so likely not the culprit

[undone coral]

why not make a prefab variant with the ovr camera rig components removed

otherwise just make a local copy of the package and modify the script

EnsureGameObjectIntegrity is called in awake and creates the cameras

[strong harbor]

I have a very specific question and I am really hoping someone happens to have either done this before me and knows of the answer.

I am currently working on a personal version of the Tiny Keep Generation Method for procedurally generating 2d levels with a form of pre set rooms.

It sucks to be stuck this early but the major first part of the method is to randomly generate rooms that specifically are not colliding or intersecting with each other at all.

Currently my set up is such that I have test prefabs that are an empty object with two tilemaps as children (1 is the walls with a collider2d, the other is the floor with no collider at all)

My main problem that i need help on, is I have been scouring the collider pages and the physics pages, but all my attempts at being able to in my script know if after instantiating a prefab if its colliding with anything has failed.

Does anyone happen to know how to solve this specific problem?

[wind badge]

If your colliders are all box colliders you may be able to simply use Physics2D.CheckBox() for every box collider in the prefab.

Alternatively you can try and fit your prefabs into discrete grid tiles to easier fit them together.

[thin mesa]

don't crosspost. also not a code issue

[torpid hawk]

sorry

[stuck onyx]

is there any way i can detect when the game is using the less GPU?

i have some secondary camera rendering operations that i launch in background and i would like to launch them when the gpu is not overloaded to avoid causing overheads

can I somehow detect when would be the best moment to launch these operations?

[novel plinth]

wut?

[stuck onyx]

i have a primary camera looking on a 3D map, but i have a secondary camera that takes portions of that 3D map from the top to create a 'map view'

[novel plinth]

Unity by default is doing it's own culling, unless you're not using it for some weird reason

[stuck onyx]

i update this portions while the user is playing, but they can be a little bit heavy sometimes, i have an array of 'areas' that need to be update and i can updated whenever I want.

so the operation is basically:
1.Move secondary ccamera to cooords x,y
2.Take a snapshot
3.Save it

i can do this while the user is playing

but i thought of just launching it if the GPU is not currently working a lot

maybe not necessary?

because the first step might take 30ms apro

if a launch that during a frame something heavy is happening might cause framedrops... correct?

So i thought maybe i can detect when the GPU is not very busy and do it there

launch it in that moment

is it stupid?

[obsidian glade]

it's not stupid but I'm not sure it's possible to do explicitly at a hardware level - you could look into slicing the workload over several frames and have the routine run infrequently, or perhaps test to see what causes the biggest performance costs and make sure you only call the routine while those aren't happening

[stuck onyx]

yes thats what i want to do but additionally i was wondering if there's some sort of indicator that can tell me when the GPU is not working too much .... like... i don't know, number of meshes rendered in that moment or something...
For my side i know when the user enters some UI menu is the best moment but i was wondering if i could also find other moments during the game

[obsidian glade]

you could look into https://docs.unity3d.com/ScriptReference/FrameTimingManager.html

[stuck onyx]

thanks!

yeah that annd this:

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

its what i was looking for i think

[pulsar raven]

thanks pangloss, I had the luck to chat yesterday with the AR glasses developers they are holding me to do it because having two requests to the motion sensor would lock it
I read a bit and am starting to understand how the java thing is working. SO I'm ditching my code but will keep this notions for the future

[placid nest]

Hi, does anyone know if it's possible to throw custom compiler errors? I want to check if a custom attribute is used in a certain class. If not throw an error, preferably in my code editor already, but just a compiler error in the unity console should be fine too

[novel plinth]

wdym? ... to throw your own exception you can do just this throw new Exception("My Exception!: Something went wrong!")

it's up to you how/when you want to throw it, either with try-catch it or just plainly throw it as you please

[upbeat path]

He's talking about in the Editor before compile time, not at run time

[placid nest]

exactly

[agile yoke]

You can produce actual compiler errors these days I believe, try googling for "Roslyn analyzers". Recent enough Unity versions support those I believe. I'm not sure how easy they are to write though.

https://docs.unity3d.com/Manual/roslyn-analyzers.html

[novel plinth]

unity has bunch of callbacks you can use in the editor... google them up real quick

[agile yoke]

Just looking for the attribute via reflection after every script recompile and Debug.LogErroring is probably easier if it's enough for you, yeah.

[mortal orchid]

In the Move function, I have put the code to move the character Left and right in the 2.5D platformer although I am changing just the x position of the character the z position also changes slightly while movement does not understand the reason.

[carmine ermine]

[undone coral]

has anyone seen an approach to developing a project template or library that would require the user to use strictly input system? I am trying to communicate to users that they cannot use Input. anywhere, and I would also want to prevent them from changing the backend to legacy input

[placid nest]

alright thank you!

[undone coral]

is there a pre-existing way to schedule a call in OnEnable that should occur after all other objects have run Start?

i think library authors might also have this problem sometimes

alternatively, is there a way to set at editor time the script execution order programmatically?

[novel plinth]

there was an undocumented attribute you can use

[DefaultExecutionOrder(100)]

[modest drum]

I have a dictionary in a class that is intialized like so...

[HideInInspector] public Dictionary<System.Type, Injury> injuries = new Dictionary<System.Type, Injury>();

But when I go to access the dictionary I get this error...

It was working completely fine before, what could have changed?

[novel plinth]

dictionary can't be serialized in unity

[modest drum]

Then how was it working before?

[upbeat path]

Irrelevant, the dictionary will be initialised with class instantiation so will be empty but not null
@modest drum Show CharacterStats code

[viral pilot]

Is there any ways to know if a Mesh.MeshDataArray is already disposed ?

For NativeArray I can use the IsCreated but I can’t find anything similar for MeshDataArray

In my case I don’t want to use the Mesh.ApplyAndDisposeWritableMeshData and still need to dispose my MeshDataArray

[novel plinth]

lol, yeah.. I didn't read his question completely, so just ignore my answer

[modest drum]

Ok, it's kinda big.

[upbeat path]

Around line 196 is good

[modest drum]

Ok

Maybe this will be enough?

    public Injury Injure(System.Type type, float severity)
    {
        Injury injury;
        
        if (!injuries.ContainsKey(type))
        {
            injuries[type] = System.Activator.CreateInstance(type) as Injury;
        }

        injury = injuries[type];

        injury.characterPart = this;

        injury.ScaledSeverity = severity;

        return injury;
    }

[upbeat path]

So, you never check if
injuries[type] = System.Activator.CreateInstance(type) as Injury;
actually has worked

[modest drum]

It has worked before.

[upbeat path]

irrelevant. check

[modest drum]

The error is thrown at !injuries.ContainsKey(type)

[upbeat path]

ok so check injuries != null. Perhaps it is being nulled somewhere else

[upbeat path]

And if you pass in a type that cannot be cast to Injury?

you do not check anything you just assume

[modest drum]

Well most of the time I'm using a generic function.

    public Injury Injure<T>(float severity) where T : Injury, new()
    {
        System.Type type = typeof(T);
        return Injure(type, severity);
    }

[modest drum]

I don't see anywhere it's nullified.

[upbeat path]

then it is time to use the VS debugger and set breakpoints

[modest drum]

The error is thrown when I try to check for the key.

I think it has to be an initialization problem

Like the dictionary was initialized when I made it in the editor

[upbeat path]

That statement is a complete misunderstanding of how Unity and C# work

[modest drum]

When the class was created through an editor script the dictionary was initialized then.

[upbeat path]

no it was not

UnityEditor does not serialize dictionaries so the Editor ignores them

[regal olive]

Hey, uh, again. How can I recreate this in Unity?

[upbeat path]

At run time the script will be instantiated and an empty dictionary will be created

[modest drum]

I will check again to see if it's nulled at any point.

[upbeat path]

easy enough, do a global search of your code for injuries

[modest drum]

Ok

[upbeat path]

VS has all of these wonderful features to help debug code both at runtime and in the VS editor, it really, really helps if you use them

[modest drum]

I'm pretty good with VS editor but I wish I knew how to use runtime better

Especially with all of the loops I make

[modest drum]

Here's all that I found.

The dictionary is never set to null

By the way the reason some of them are lists is because that's my save class where the data is converted from list to dictionary.

[quiet bolt]

Is it possible to check if a Method has been called from the same class or an outside class? For example ”if method is called from the same class, do this, else, do something else”

[upbeat path]

yes, but you need to use Reflection to query the call stack, not a trivial thing

[quiet bolt]

I see

I did read about a stackoverflow thread about this and they also mentioned reflection

Problem is that they used derived clases in their situation which is not really what i want

[upbeat path]

Reflection should never be used in game dev unless absolutely necessary, it is slow and heavy

[quiet bolt]

I see

[upbeat path]

You are going to need to breakpoint this to see what is happening because, as far as I can see, injuries should not be null

[modest drum]

I'm assuming I breakpoint when it checks for the key

[upbeat path]

yes

[modest drum]

And then check what the value of injuries is?

[upbeat path]

yes

[modest drum]

Ok, one sec

[upbeat path]

actually breakpoint the Debug.Log at 194 and step the code

[modest drum]

ok

For some reason it always asks me which instance to attach to

And I never know which one to do

[upbeat path]

which Unity version and which VS version?

[modest drum]

How do I see VS version?

[upbeat path]

Help->About

[modest drum]

Ok

Unity version 2021.3.3f1, VS version 15.7.3

[upbeat path]

It should connect automatically, do you have multiple projects open?

[modest drum]

No, but I think I just selected the correct one from the 3

[upbeat path]

Ok. so at least Unity/Vs are not lying.
I think you need to post the CharacterStats script to a paste site

[modest drum]

Ok, can I just send it through a file?

[upbeat path]

ok with me, dont know about the mods and the 'rules police'

[modest drum]

This should be it

Looks like you can view it all through discord

[upbeat path]

To start with, Unity really does not like having multiple classes defined within one code file

[modest drum]

Sorry yeah I know I need to fix that.

[upbeat path]

Does injuries really need to be public?

[modest drum]

Well I never thought about it but I think it does have to be accessed by my data saving class so yeah.

Actually

Maybe not

Wait no it does

[upbeat path]

I'm wondering if you are deserializing incorrectly and CharacterPart.injuries is being nulled during the deserialization

[modest drum]

You mean when I load the data?

[upbeat path]

yes

[modest drum]

Well the script is currently not being used so I don't think that would cause it

But I can send my data script just in case

[upbeat path]

I would be tempted to add this

    if (injuries == null) injuries =  new Dictionary<System.Type, Injury>();

above the containsKey.
something is corrupting the class but tracking it down is going to be a pain

[modest drum]

I added that before and it worked but yeah, it doesn't seem right.

I will say that the part class is NEVER created during runtime, it's only ever created in the editor

That could be what's causing it

[upbeat path]

the class must be instantiated at runtime otherwise you would not be able to use it

[modest drum]

Well maybe the engine does that part for me, but I never type new CharacterPart() through code

This is so I can use it in my custom editor to easily make parts for the character

[upbeat path]

CharacterPart part = new CharacterPart (characterStats)

from your CharacterStatsEditor code

[tired creek]

When I create a dll for Unity in C# I can add UnityEngine to assemblies and use UnityEngine functions in my code. Can I do the same when developing dll in C++?

[modest drum]

Oh well yeah that's done through the editor

[upbeat path]

C# dll, yes, no problem, C++, no

[tired creek]

okay

too bad

[alpine adder]

do you all have recommendations for how a unity dev can move into a c++ position? is it best to just create small projects to put on the resume?

[compact ingot]

small but non-trivial projects are good to show in addition to what you have on your CV. It will depend a lot on what the C++ is looking for as it has a wide range of applications where even existing skills in C++ don't translate. Generally gamedev in C++ is looking for a rather low-level/advanced understating so you can build engine features / integrations, possibly the position is for engine tooling (which is an altogether different skillset). I'd expect most C++ to require some sort of "is comfortable with large existing codebase", and that skill comes from working in and reading a lot of C++ other people have written so you know all the different quirks and preferences people have.

[tulip lichen]

Gravity seems to still be framerate-dependant despite being in FixedUpdate() rb.AddForce(Vector3.down * gravity);

[compact ingot]

gravity should be applied with ForceMode.Acceleration to make it independent from an object's mass

[alpine adder]

Very interesting so my situation is I am a lead developer for AR/VR application for my company and a previous full stack. I would like to make the move to lower engine c/c++ but not sure how to make that step

[compact ingot]

i think its one of those things that have no clear cut answer, those positions are rare and require a lot of skill, suppose most people started as interns at one of the companies or have "always" been tinkering with they personal pet engine

[tulip lichen]

Still, I'm only facing issues when switching framerates, even after setting it to Acceleration. I think my issue is when I'm lerping position rather than gravity tbh, but Vector3.Lerp() is also called in FixedUpdate so I'm not so sure. From what I can see, increasing the lerp t value reduces difference between framerates

[compact ingot]

why/what are you lerping in a physics simulation?

[tulip lichen]

For smooth movement

[compact ingot]

what exactly are you lerping?

[tulip lichen]

transform.position

[compact ingot]

that makes no sense

[tulip lichen]

transform.position = Vector3.Lerp(transform.position, newPos, lerpValue); like so

[compact ingot]

it would fight the physics engine's own interpoilation

yes, dont do this if the transform is also controlled by a rigidbody

[tulip lichen]

The thing is, I'm only using AddForce for gravity, everything else is through setting position manually

[compact ingot]

you cant do this

the systems will fight each other

[misty glade]

You either "use the entire physics engine" or you use none of it and set every position manually

it's.. typically not a mix and match sort of thing

[tulip lichen]

I guess that makes sense yeah, thanks, I'll see how I can apply gravity without AddForce then

[misty glade]

you don't even need to apply gravity... you just... configure gravity

[compact ingot]

also, use rb.MovePosition() if you want to use colliders of any kind (not transform.position = whatever)

[misty glade]

check box, next feature

🙂

[compact ingot]

but thats specifically what will not work (nicely) when moving everything else with transform.position

[tulip lichen]

I find it easier to just script my own gravity than make that one not feel floaty and awful

[misty glade]

that's what I'm saying 🙂 turn off all your lerping and position fiddling and enable gravity instead (if gravity and physics are what you're trying to emulate)

if you want to roll your own physics, that's fine too

just a bit more work than most people want to tackle, i think

[violet wolf]

but its only floaty if you don't work with it

Turning that on enables gravity, but that doesn't mean you do nothing with it

[tulip lichen]

I'm aware, I just find it simpler to make my own

[compact ingot]

its probably the global constant that is applied to all objects equally, usually you want to make stuff selectively more snappy by setting gravity on an object by object basis

[violet wolf]

well true but that's why you can use multipliers, setup controllers with curves etc

I just feel like doing it all on your own is more work than its worth

I guess though that comes with my own bias

[compact ingot]

it depends on the game and how much it aims to use simulated physics vs how many tweaks it requires

[violet wolf]

Yeah that's true, I guess if you don't need it then don't use it

[compact ingot]

a kinematic controller is a ton of (frustrating) work for sure

[tulip lichen]

So ignoring everything else I had wrong, putting an AddForce like so: rb.AddForce(Vector3.down * gravity, ForceMode.Acceleration); in FixedUpdate() should make it framerate-independent, is that at least correct?

[sly grove]

yes

assuming gravity is expressed in "meters per second^2"

[viral pilot]

Is there any ways to know if a Mesh.MeshDataArray is already disposed ?

For NativeArray I can use the IsCreated but I can’t find anything similar for MeshDataArray

In my case I don’t want to use the Mesh.ApplyAndDisposeWritableMeshData and still need to dispose my MeshDataArray

[sly grove]

maybe Length becomes 0? Not sure.

[undone coral]

you mean at e.g. a large game studio?

[undone coral]

is there a native pointer for it? it will be intptr zero if it's disposed

is there a way to propagate clicks for all event receivers instead of the most foregrounded one?

do i have to modify event system or input module to achieve this?

[strong harbor]

is there a particular reason that after spawning an object on top of another both with box colliders, then running the boxcollider2d.cast function returns no results?

it has been ruining my mind attempting to just simply know if two prefabs are spawned on top of each other

[sly grove]

the first part of the question doesn't really seem relevant to the second part

If you want to know if a collider is inside a box you would use OverlapBox or CheckBox

[strong harbor]

hmm

let me see if I can elaborate

Right now the problem I have been having is that I am trying to spawn in a bunch of prefabs in @ random locations that all have box colliders (previously tilemap colliders), and the scripts goal is to only spawn a new prefab in at the random position as long as it isn't touching any already existing prefab.

[undone coral]

https://open.spotify.com/track/4uz9FU7VWNhTj5SO7WpSiK?si=2e93ff9315404d91

[undone coral]

this is a pretty common problem

[strong harbor]

that makes me very hopeful that there is a common solution

[undone coral]

you can read the box collider's bounds and perform an overlap box on the candidate position

[strong harbor]

can you do the same thing with a tilemap collider?

[sly grove]

sure

so

do a Physics2D.CheckBox

if it hits something, don't spawn there

if it doesn't, spawn there

[strong harbor]

so i notice that checkbox only exists for Physics

or i cannot find any such function for Physics2D

[sly grove]

https://docs.unity3d.com/ScriptReference/Physics2D.OverlapBox.html
overlap then

[undone coral]

🎶"Put the numbers on the box, and then you Overlap" 🎵

[strong harbor]

lets find out if this works

actually would the overlap box

return null

if nothing was hit?

or would the collider2d just be empty

[sly grove]

If only the docs covered this possibility... oh:

Null is returned if there are no Colliders in the box.

[undone coral]

🎵 Make sure you write this on the OverlapBox, and then you wait wait wait wait ...🎶

[strong harbor]

ok normally i am very good about reading documentation i genuinelly dont see that line but i trust you

oh wow its the last line

welp

reading the documentation explains the documentation huh

[spring flame]

I wanted to use DOTS for pathfinding with thousands of agents, but I know the current DOTS system for Unity is still in an alpha phase, would you recommend trying to use it?

[compact ingot]

any decently performant pathfinding solution will be implemented in a data oriented way, you do not need to use DOTS for it, it is (can be) completely separate from everything that needs to involve the engine

[undone coral]

navmesh is really performant

you're confident you can't use it?

[spring flame]

Not at all, I think NavMesh should be usable but elsewhere I've received advice to look into Dots/ECS

[regal olive]

Have i just overcomplicated this or is this a good solution? https://paste.ofcode.org/uqA4SqpiP7guGjgwPrF8fx

[frigid cloud]

if I am using terrainData.GetHeights what width and height correspond to 1 world unit within Unity? 1 is too small. does it depend on the terrain settings?

[undone coral]

hmm

well what's your game?

[spring flame]

The vague idea is a total war clone

It's not meant to be a real game

Just a practice project

That's another reason I wanna try ECS and DOTS, to move out of my comfort zone

[undone coral]

oh yeah

we discussed this before

it will be cool to try to do RTS

this way

i don't know if ecs & dots plays well with navmesh

but navmesh itself can do starcraft 2 movement as performantly as starcraft 2 does

because it's almost exactly the same technology

i'm not sure what total war's approach is

[spring flame]

The biggest issue I'm getting is getting agents to avoid colliding /merging into eachother

Notice how at the end they basically merge together

B/C right now I'm telling them "go to the enemy position". Which obviously isn't correct but I don't know any other solutions.

[fierce glacier]

public class ObjectResource : MonoBehaviour {

    [SerializeField] private float _speed = 10;
    public GameObject cam;

    void Update()
    {
        
        //Movement Moment

        if (Input.GetKeyDown("space"))
        {
            print("space key was pressed");
            cam.transform.position += new Vector3(1, 0, 0) * _speed * Time.deltaTime; ; 
        }

    }
    
}```

Is there any reason the camera won't transform?

The print statement triggers, and its assigned

[spring flame]

Did you ever assign cam

Also check speed in the inspector, sometimes the inspector overides code for some reason

[thin mesa]

not an advanced question. but do you have anything else that controls the camera's position like cinemachine?

[fierce glacier]

nope

And cam \speed are assigned in the inspector

Idk what happend, this code worked an hour ago

Im going to relaunch\reboot and hope lmao

[hoary pendant]

Starcraft 2 handles collisions by not modifying the astar route of an agent, agents in the way of the moving agent will move out of the way to let them pass

[spring flame]

Interesting, do you have any resources that describe that further

[hoary pendant]

https://www.gdcvault.com/play/1014514/AI-Navigation-It-s-Not really good talk about industry approaches, and also, there is a lot of research about pathfinding as it is an issue outside of gamedev as well if you want to look into papers about those

So what you could do to emulate this is have agents in a settled state record their current position. While agents in a pathTo state when collided with settled agents, will modify the settled agents to an unsettled state to move away/pushed away, which after a delay will attempt to move back to its settled position. The unsettled state can cause a collision cascade to part large groups of settled units if an agent goes thru the middle

[vestal lily]

Does anyone know how unity determines the angle between two vectors when you Slerp between them?

[untold moth]

Something like that probably
https://stackoverflow.com/questions/67919193/how-does-unity-implements-vector3-slerp-exactly

[vestal lily]

oh thank you ill see if its similar enough

[vale ginkgo]

Any tips on having too many variables in a script? My player controller has 120 lines of variables, some of which are private, some are editable via the inspector. They are currently grouped by category, any other tips on managing them? Theres so many its starting to get hard. Thanks.

[misty glade]

break your classes into partial classes

and probably rethink how you've composed your objects.. 120 variables is fairly absurd

someone somewhere said each class should only have 2 public members, but .. i think that's hogwash as well.. but.. 120 is definitely grounds for refactoring

public class MyPlayer : MonoBehaviour
{
  public EntityMovementInfo MovementInfo { get; set; } // details like x/y, gravity, crouching/falling/swimming/climbing state, etc
  public PlayerCurrency Currency { get; set; } // player money
  public UpgradeInfo Upgrades { get; set; } 
}

etc

[misty glade]

https://williamdurand.fr/2013/06/03/object-calisthenics/#8-no-classes-with-more-than-two-instance-variables

[vale ginkgo]

Thanks

[vale ginkgo]

Ill look into it

[misty glade]

FWIW the article is very opinionated - lots of people will argue lots of points in that article.. but fwiw I use the "never use else" thing now and rather like it

most of my methods take the form

public void SomeMethod(int someInput)
{
  if (someInput == 0) 
  {
    ComplainAboutInput();
    return;
  }
  if (someInput > MaxValidInput) 
  {
    ComplainAboutInput();
    return;
  }

  DoSomethingWithInput(someInput);

}

instead of the "normal" way:

if (someInput == 0 || someInput > MaxValidInput)
{
  ComplainAboutInput();
}
else
{
  DoSomethingWithInput(someInput);
}

[vale ginkgo]

Thats interesting, I learnt at University to only ever have one return statement.
I also saw articles on the internet saying not to use partial classes

[misty glade]

I think opinions on that are mixed and valid in different contexts

my validation methods would be a nightmare if i didn't use the early return though

[vale ginkgo]

yeah, it gets like that. I was reading the article you sent, so the basic idea is to make a bunch of objects to encapsulate most of the required variables

[misty glade]

etc

could you imagine that method with nested ifs?

basically you check every way to fail

[vale ginkgo]

It would be horrible, yes. The idea with a single return statement is that the program flow is obvious and easy to follow

[misty glade]

and if nothing failed, succeed

i mean.. i would argue my validator is "easy to follow"

[vale ginkgo]

yes, its not misused. Theres no nested ifs there at all, which immediatly makes it harder to read

[misty glade]

yeah - i think having limited/no nested indentation AND the early return are sort of .. complementary

if you're doing all kinds of nested ifs and some early returns, that is definitely a pain in the ass to read and figure out

[vale ginkgo]

its more about consistency than strict rules you must use

[misty glade]

yeah.. as far as the whole "bunch of objects to encapsulate" - it's.. helpful but only if you don't go too wild, because otherwise it's a lot of paperwork and "what stupid class holds this variable"

as long as it makes sense for you it's fine

but 100+ variables immediately feels like too much unless they are incredibly cohesive or .. something

my player model has about 15 members and is probably already ripe for a refactor:

but in my mind, everything is relatively easy to find

ActualScreenTaps and DeviceId for example could probably go into some sort of meta-metrics object 🤷‍♂️

[vale ginkgo]

ok, thanks for the tips

[regal olive]

https://static.wikia.nocookie.net/4d-miner/images/6/65/FrankRotate.gif

It has been a few days

I have no idea how to recreate this in unity. Can anyone help?

[regal olive]

Any help?

[regal olive]

Probably need to use some shader

[wary swift]

since from the looks of it, it uses a 3d world as base, you'd first need to take an arbitrary direction, and then simply check if any lines of the blocks intersect with the "plane" (the transparent one), and then generate and store points where they intersect.
So lets say your plane is facing forward (0,0,1) that'd mean you want to essentially remove the z axis, and only grab points which z value is 0, but any x and y value is allowed, since those would always be on the same plane.
This is essentially the easy version
now it gets a bit more tricky when you have a plane facing in multiple coordinates, such as (0.577, 0.577, 0.577) which is a vector3.One normalized
for this you can use Vector3.Dot product (Vector3.Angle / Vector3.Project would also work) to calculate if they're on the same plane. store those values somewhere, generate a new mesh based on those points, texture it appropriately, and bam, after all that work you should end up with an effect like this.

a naive approach to doing this would be to simply rotate the camera around the character but this is extremely unlikely to work for a variety of reasons
i also noticed that this image belongs to some steam game called 4D miner so i'm not sure how i feel about explaining all this 😂

Since a picture says a thousand words, this best showcases what i'm talking about when i meant grabbing the points that are on the same plane

[obsidian glade]

nice find on it being from the 4D Miner game 👍 confused why it wasn't included in the original question to begin with as the steam page does a great job of explaining the intent

[bronze summit]

Let me know if this doesn't fit here:

I have a "pick the answer" section where the submit answer button appears partially on top of an answer tile.

If you hover over the button/tile overlap, the button doesn't detect you're over it. If you hover over the part of the button that doesn't overlap with the tile, it functions normally.

Does anyone know if this is a raycast thing fighting between physics and ui elements?

[long ivy]

maybe the ray is being blocked by the tile's collider. Try changing your raycaster's BlockingObjects value

[bronze summit]

I'm not using a custom raycaster, but I am using one camera for the game world and another camera for the ui canvas

[long ivy]

And the graphic raycaster on your canvas, did you try changing the field I mentioned?

[sly grove]

Could be. You can set a layer mask for your event system

[undone coral]

does anyone have experience rendering in batchmode?

i am trying to figure out how to recreate the unity renderloop

and i am struggling with recreating the staggered behavior of the render thread finishing a frame after the next frame begins on the CPU thread

[undone coral]

on metal it works... and on directx it does not 😦

okay better question - how do i get insight as to why the main thread is waiting on the render thread?

[bronze summit]

The ui canvas is set to none atm

Whats strange is that if the distance from the ui button to the ui camera is shorter than the distance from the tile to the game camera, the button works as expected

[bronze summit]

I don't see a field specifying layer mask, unless you're talking about the layer field next to the tag field below the game object name

[woven kettle]

Hello,

I want to create a spell that only affects people in front of the player in a 3d corn shaped area or any alternative shapes ( if it would be more optimized than the 3d corn shape )

as a compromise for a better performance, a simple cuboid shape like this one would work
( although , I don't allow the spell much , only 6-20 times per match )

[sly grove]

I'm talking about on the event system

[bronze summit]

Do you mean change the layer the event system is on? That's the only thing that mentions layer on my event system

[sly grove]

No

By my event system I meant the unity default event system

[sly grove]

Might be on the physics raycaster on your camera

Or the input module. One of those three

Im not at my computer right now

[bronze summit]

Found it. I'll play with that

[sly grove]

There's a mask on the graphics raycaster too

[undone coral]

how might i do this? visibleReflectionProbes is a NativeArray

[bronze summit]

For both the physics and graphics raycast, the source is the camera?

[undone coral]

alternatively is there anyone who can make heads or tails of how to use this approach to just... add an object to the culling results?

not seeing anything about render probes in https://github.com/alelievr/HDRP-Custom-Passes/blob/master/Assets/CustomPasses/SeeThrough/SeeThrough.cs

the context is the render probe gets culled out for some reason after my camera moves a distance away from the place it originated in the scene

[undone coral]

alright

i forked the hdrp package

now i just need some insight as to how to modify that value

custom passes won't help

[undone coral]

https://forum.unity.com/threads/hdprobes-are-culled-when-rendering-to-a-rendertexture-even-though-they-shouldnt-be.1309524/

well i fixed it with a workaround

[bronze summit]

Is there a priority system? Because while I have the button and game object triggering confusion, if I put a pop-up overlay blocking the screen, it'll successfully block the tap, and neither game object nor button will trigger

The pop-up also has its own camera

[wooden cedar]

We do this in one of our horror games for the flashlight. We rounded the end though a little bit so it didn't end so abruptly. It works great, just use it as a trigger

In our case the flashlight burns and kills the evil creatures, so we added two colliders a short range and a long range for different values of impact.

[thin mesa]

don't crosspost. also not a code issue

[finite merlin]

Sorry but I need solution quickly

[thin mesa]

then ask in an appropriate channel. this is a code channel, but your issue is with creating specific files in the editor. although you can just create the files in your IDE if you need a solution immediately and cannot wait or even just in your file explorer

[finite merlin]

Thanks man you solved it

[regal olive]

I have a game where I know the location and velocity of my target. I know my own location and the speed of my projectile. I want to Aim at moving target (or predicting target's position at time it takes for projectile to hit it)

[fresh salmon]

Lots of math inbound
Search for "projectile leading" on Google

You basically need a formula that will calculate the intersection point of two moving objects

[errant plinth]

Adding a bit of spread can make dodging harder

Does anyone knows if the values in "HumanPose.muscles" are in the same range as the "MuscleHandle.SetMuscle" ones?
https://docs.unity3d.com/ScriptReference/HumanPose-muscles.html
https://docs.unity3d.com/ScriptReference/Animations.MuscleHandle.html

The docs says the "HumanPose.muscles" is:
A muscle value moves a bone for one axis in the range [min,max] define in Humanoid Rig. See Also: HumanTrait.

But says nothing about the values that "Animations.MuscleHandle" accepts

[icy smelt]

Does anyone knows why the HumanBone muscle, position, and rotation are different from the ones expected in the MuscleHandle and AnimationHumanStream expect?

If I multiply the HumanBone muscle values by some factor like 0.01f and use them in the AnimationHumanStream, they work as expected

But idk why the values expected by the MuscleHandle are smaller

Maybe there is a ratio between the Muscle values and the avatar size, idk

Any idea?

[undone coral]

do you mean at runtime?

how ar eyou using these values?

[undone coral]

i don't think they are. it's going to be that you are importing an fbx from maya, where the units are 1cm, versus unity, where the units are 1m

that's why it's 0.01f

you are converting from unity to maya (model) units

[icy smelt]

I'm getting the muscle values from a humanoid using the HumanPoseHandler

Then I'm applying these values with an AnimationHumanStream

I'm getting the muscle values from a humanoid using the HumanPoseHandler
Then I'm applying these values with an AnimationHumanStream

These having nothing to do with FBX

I'm using animations imported from the editor

[undone coral]

what is your objective? animation retargeting

[icy smelt]

Sorta

[undone coral]

from that guy who authors all the assets for it

and trying ot use it in some motion matching* thing?

[icy smelt]

Nah

[undone coral]

well

what is it then

i don't mean specifically an fbx, but you're asking for a guess as to why the specific factor 0.01f works

[icy smelt]

I'm just making some tests. I'm reading the HumanPose from a character, generating some data, then using these data in animation jobs to reapply them to another character

[undone coral]

and my guess is because a resource is authored in maya

[icy smelt]

Yes, the 0.01f factor works, but it makes no sense

[undone coral]

i know maybe you didn't author it in maya

[icy smelt]

The HumanPoseHandler should not work different based on the source GameObject

[undone coral]

i think you are not going to succeed in doing animation retargeting

it isn't anywhere near as simple as you think it is

a lot of people have aspired to do something ismilar

something something, retarget humanoid animation from a source library

[icy smelt]

I don't want to retarget specifically, I'm first testing if it could work to play legacy clips as humanoid. So far, by using the 0.01f scale, it works

[undone coral]

okay well i'm trying to say

that those legacy clips are a humanoid animation probably authored in maya

[icy smelt]

I see, the scale I use when importing FBX in runtime is (original scale / 100)

[undone coral]

thank you for listening to me

[icy smelt]

1 / 100 = 0.01

But

[undone coral]

but seriously you shouldn't try to do this it will not work

you will not succeed in retargeting animations

of course everyone wants to reuse humanoid animations. there's a middleware for that

you have to use the middlewares

it's unavoidable

[icy smelt]

Why are these scale values applied to muscle animation? It makes no sense

[undone coral]

in one place you are querying the data as it was imported, and in other is the data as it exists in runtime

[icy smelt]

It makes sense for muscle values to be normalized

HumanPoseHandler queries imported data? It makes no sense, as I can change an entire humanoid hierarchy manually, and use an avatar created based on the same hierarchy

[undone coral]

alright let me put it differently

[icy smelt]

But the avatar could have these scale values internally

[undone coral]

you are querying a middleware

you don't nkow anything about how the middleware works, it's a black box

you can either do exactly something the middleware supports, or you can try to do arithmetic which will never work

anyway just htink about it

[icy smelt]

So you are telling me that these scale values are somehow stored in the avatar?

[undone coral]

ohh!

you're not doing retargeting you're authoring the thing that imports models at runtime

[icy smelt]

I do

[undone coral]

i guess you are trying to solve both problems

[icy smelt]

I'm implementing something to play legacy animation clips as humanoid ones, using animation jobs

I'm 90% sure it is possible

[undone coral]

i don't know anything really about avatars so i'm sorry i can't be more helpful

[icy smelt]

I've basically nailed it, besides the scale issue

But now that you said

The scale thing coming from the original model scale makes sense

Bc of the 100 / scale math I use when importing the models at runtime as well

The scale makes sense for muscles

But does not work for bodyPosition and bodyRotation

Rotation should not be scaled at all, as it makes zero sense to do so

So far:

TriLib 2.0 - More progress when playing legacy animations as humanoid ones. The "test" clip is imported as legacy and converted/played as humanoid at runtime (local root position and rotation not applied, that is why the animation still looks odd)

[undone coral]

look great!

[icy smelt]

I've figured it out

Tks

[undone coral]

sorry i don't mean to be discouraging

it's just hard to know how sophisticated people are

[icy smelt]

The muscle scale is based on the original model scale while importing btw. I need to test it with clips I import myself (this one was imported in the editor as legacy)

In this case, I know the FBX scale is 100 / model original scale

The model local rotation is the same (rotation has no scale)

The local position (body position) can be stored relative to the avatar scale (normalized)

So when reading the animation values with the playable, I multiply it with the avatarScale coming from the playable stream

And I get the position fixed

Now I'll try to extract the root motion when converting the clip

I might release this stuff on GitHub, there are many other users who want to use this feature as well

[civic kestrel]

I am having trouble adding slopes to my autotiles. Any Help?

[timber depot]

I get two errors with that.
Top-Level statements must precede namespace and type declarations
The modifier 'public' is not valid for this item

[misty glade]

Not a #archived-code-advanced question if you don't know how. 🙂

Put the enum in a file by itself, put it in a namespace. Put the GetColor method in a class of your choosing - probably make it static as well:

/// ColorUtilities.cs
namespace Kei
{
  public enum MyColorEnum { ... }
  public class ColorUtilities
  {
      public static Color GetColor(MyColorEnum type) => type switch { ... }
  }
}

might be syntax errors in the above, just dashed it off, but you should get the idea.. get your color with:

using static Kei.ColorUtilities;
...
Color c = ColorUtilities.GetColor(Alice_Blue);

[urban warren]

I got my self a design question again. This is mostly me not being able to make my mind up.

So I am making a node graph akin to ShaderGraph (but more 'live data' type thing than code gen). I am trying to figure out what the best way is for a input(destination) port to get the value of a connected output(source) port.

I see two options, I could either have it so that when the value of the source port changes it also sets the connected destination port's value.

class Port
{
  private object _value;

  public object Value
  {
    get { return _value; }
    set 
    {
      _value = value;
      OnValueChanged?.Invoke();
    }
  }
  
  public event Action OnValueChanged;

  public void ConnectToDestination(Port destination)
  {
    OnValueChanged += () => destination.Value = Value;
  }
}

Port sourcePort = ..;
Port destinationPort = ..;

sourcePort.ConnectionToDestination(destinationPort);
sourcePort.Value = 5;
// destinationPort.Value now == 5 as well because of the OnValueChanged event.

Or I could have destination port store a reference to the source port, and get the value directly

class Port
{
  ..
  private Port _sourcePort;

  public object Value
  {
    get { return _sourcePort != null ? _sourcePort.Value : _value;
    set { .. }
  }

  public void ConnectToDestination(Port destination)
  {
    destination._sourcePort = this;
  }
}

The first way is more disconnected, but almost feels too disconnected, while the second option feels a bit messy/ridged...

[dusky carbon]

IMO the former seems simplest (but there is no reason you couldn't store the actual _destinationPort if you wanted to), the latter is awkward as you'll have yourself reaching backwards n times any time you want to read the value.

[urban warren]

That is a good point about 'reaching backwards'. Thanks.

[tender light]

Hmmm. Also if you consider disconnecting from the destination port. I think its much simpler to just be able to remove a reference and not have to search for the delegate to unregister it.

[jolly verge]

can anybody help me make enemies spawn and go straight down in my 2D game?

[urban warren]

I actually have a Connection class that has a reference to both ports and has a method that it adds to the event. I just removed it from the code I posted to simplify it.

[urban warren]

That is a #archived-code-general or #💻┃code-beginner question 🙂

[jolly verge]

Ok thanks

[slow walrus]

I have a stupid question that I think belongs here
What type do I give GetPixelData<> when the texture format doesn't have an equivalent type in C#? For example, when a texture has the format GraphicsFormat.R16G16B16A16_UNorm

[dusky carbon]

Looking at the source for GetPixelData , you might be able to create a struct with a size of 64 bits and use that for T. Maybe just a single ulong inside the struct, then you'll have to parse from that if you want to do something with it.

[slow walrus]

yeah, I've done a test where I've been able to use half4 without any errors but obviously the data gets garbled when I try to set it

would you know how I would have to parse that data? or any reading material you could point me towards?

[dusky carbon]

you can just use bitwise operators, if ulong mask = (1 << 16) - 1;, you can access R with val & mask, G with (val >> 16) & mask, B with (val >> 32) & mask, etc
btw I'm not sure if they are ordered in this way, it might be the reverse

[slow walrus]

I'm with you that far, at least in theory. And I maybe should've mentioned this initially, but my goal here is to write to this array

is there some definition of what a unsigned fp16 should look like - or how do I figure out what to actually set those bytes to?

[dusky carbon]

https://docs.unity3d.com/ScriptReference/Mathf.FloatToHalf.html this maybe? and this for the other way around https://docs.unity3d.com/ScriptReference/Mathf.HalfToFloat.html

also reading this reminds me that ushorts exist so you could probably just make your struct { ushort r; ushort g; ushort b; ushort a; } and ignore bitwise math lol

[slow walrus]

oooh, I'll give this a go! I'm a little bit cautious about the bytes of a float and int being used in the same way, but maybe that's a thing?

[dusky carbon]

bytes are bytes, just think of ushort as a 16 bit container, sure when you do operations like + and - on them they are interpreted as integers, but you are free to interpret them however you wish

[slow walrus]

sure, but if the GPU or the rest of unity doesn't interpret them the same way then it gets a bit painful, right?

like if I don't assign them in the same way, then in theory I'd have to parse them on the shader side - meaning that only supported shaders would be able to read my texture?

[dusky carbon]

let's back up, why did you bring up fp16s? do you see documentation confirming that those are the types for each component in this color?

[slow walrus]

Ah, right you are. Sorry, I was dealing with floats earlier and got stuck in my thinking there

A four-component, 64-bit unsigned normalized format that has a 16-bit R component in bytes 0..1, a 16-bit G component in bytes 2..3, a 16-bit B component in bytes 4..5, and a 16-bit A component in bytes 6..7.

If I'm understanding this right, it doesn't say anything about what type of data they hold - just which ones hold which channel

[dusky carbon]

I saw that in the unity docs, but I don't have much certainty in what "normalized format" means

https://www.khronos.org/opengl/wiki/Normalized_Integer I think this is it, let's read

ok they are literally just ushorts, but in the context of being read by something that expects color values between 0 and 1 it is divided by 2^16-1

[slow walrus]

Ah, nice - then making a struct that holds 4 ushorts should 'just work'

thank you very much for the help!

[dusky carbon]

would like if you'd report back with success

[slow walrus]

will do! I'll let you know either way

[unborn bramble]

Greetings, i am having trouble with Unity's meshFilter.sharedMesh.normals property where the property is giving me invalid normals. My goal at the moment is to get a normal for each side of a dice seen here:

However, what unity gives me in return is what the gizmos draw as seen here:

Here is the code responsible for fetching the normals and drawing the normals https://gdl.space/inururetid.cpp

[slow walrus]

looks to me like you're just grabbing the normal of the first 4 vertices and displaying those - which is probably not what you want

[dusky carbon]

yes, that mesh probably has way more vertices than the number of sides, I doubt it is just vertices at the corners, and even then there isn't a magic mapping between dice sides and vertices, you'll have to inspect the mesh in some meaningful way to determine which vertices lie in the faces.

[slow walrus]

So it wasn't working and I've been trying different things to make sure I wasn't being an idiot. I was just taking this screenshot to show you how it wasn't working when I thought I'd just verify a couple of values to make sure everything correct one last time

Sure enough, everything looked good... But the texture is suddenly correct??

[dusky carbon]

wait is it incorrect or correct now? lol

[slow walrus]

after adding a couple of breakpoints it's now correct (2nd screenshot)

and I can't make it incorrect anymore

[dusky carbon]

confusion, but grats

[slow walrus]

Thanks!

I literally have no idea why

but I will take it

thanks again for the help!

[dusky carbon]

always feels good when an actual advanced problem gets a solution

[unborn bramble]

Indeed, i found out after some experimentation with a colleague

Is there a method to which i can get the normal of a face and not a specific vertex?

Since i would be near impossible for me to find the correct vertices to triangulate the normal myself, especially with the amount of vertices in the model.

[slow walrus]

It can be confusing because DCCs lie to you but faces don't have normals, they are per vertex

even if they did, your model looks to have a good number of triangles as well so it wouldn't make things much easier I'm afraid

my suggestion would be to create some custom concept of a surface/normal instead of relying on the mesh

just an array of vector3s that you can define in the editor

and then when you want to do whatever it is you're doing (checking which one is pointing up?), you multiply that vector3 by your dice transforms TRS

[dusky carbon]

i suggest: throw this script on your obj with the mesh, play around with selectedIdx in your inspector until it is on a face vertex, note the index and its corresponding die face number, then move onto the next face https://gdl.space/acosucelum.cs

[slow walrus]

that works too, but it's worth noting that everything will break horribly if the model is updated

[dusky carbon]

absolutely

and even then, it might not have vertices in the face to use depending on the mesh detail

[slow walrus]

for a quick and dirty solution, you can have a child transform per face that is oriented in the direction you want

then you can just get the transform "up" direction

but this is not the most performant solution because the child transforms have to be updated every frame

[unborn bramble]

Will test both when i have time, cheers ❤️

[scenic forge]

Manual (https://docs.unity3d.com/2021.3/Documentation/Manual/CSharpCompiler.html) says init only setters and by extension record types are not supported, but can be worked around by declaring your own System.Runtime.CompilerServices.IsExternalInit.
What's the implication of doing so (2021 LTS, IL2Cpp)? I do want to use these features but I can live without them if it has negative impacts.

[dusky carbon]

presumably your custom System.Runtime.CompilerServices.IsExternalInit is in the path that produces the IL so I wouldn't think it would matter with respect to IL2Cpp

[scenic forge]

🤔

[dusky carbon]

Have you just tried declaring your own and seeing what happens when you use those features?

[scenic forge]

Nope, I was hoping to find more information but almost all mentions of System.Runtime.CompilerServices.IsExternalInit simply shows you the workaround but doesn't say much about how it works under the hood.

I'm assuming stuffs under System.Runtime.CompilerServices are all executed at compile time and has no runtime implication?

[fresh pollen]

Quick question my dudes, is it worth creating a global cache of commonly used integers and floats like 1, 2, 3, 1.0f, 0.5f for the sake of not generating additional garbage?

For example, a "Numbers" class with a constant like Numbers.THREE_INT which would then be used in something like

if (shotsFired >= Numbers.THREE_INT) {
 // Doing something after the 3rd shot
}

Is that excessive? Does C# cache stuff like that automatically after compiling?

[tough knoll]

Woah. I had no idea this was a thing

[dusky carbon]

my message there was a bad idea, we went with a custom struct with 4 ushorts

[tough knoll]

Oh

Okay, I scrolled past the middle and saw success at the end xD.

That's pretty cool though

I recently did some stuff with combining lightmap textures and I gave up entirely and wrote a c++ program to do it for me using openEXR

I bet this would have worked

[dusky carbon]

There's always next time I guess!

plus I bet your c++ program is performant as heck

[tough knoll]

its not for runtime 🤷‍♀️

[dusky carbon]

oh lol

[tough knoll]

I'm not a c# runtime expert, but like, would that not just be a constant pointing to another constant. I imagine this would actually get optimized away by the compiler, but what

Okay, so after googling, it does not get removed by the compiler because it needs to be accessible to reflection. So you'd just be adding garbage fieldinfo to no benefit

[fresh pollen]

Thanks for the response homie. Aye, I see your point. And for integers that makes more sense, but surely there is some sort of garbage when checking against some sort of random float value like 0.05235, right?

[tough knoll]

just dont worry about it

constants are constants

[fresh pollen]

and 0.05235f gets compiled down to a const behind the scene?

[tough knoll]

Anything you type into an evaluation is a constant

Unless it's like

a struct you're creating in the evaluation

[fresh pollen]

Cool, thanks for the info @tough knoll, I really appreciate your time.

[novel plinth]

If you knew you're going to do that often in your game, just pool them with ArrayPool https://docs.microsoft.com/en-us/dotnet/api/system.buffers.arraypool-1?view=net-6.0

even if you forgot to return it back to the pool, it will just be treated as regular allocation. Meaning, it's pretty much safe

[austere jewel]

The point of arraypool is to pool arrays, not to pool the values you store in them

if you moved some ints into arrays for no reason you'd be causing more waste than just using constants, which are extremely free

[peak plover]

hey do somebody can help me in code-general or beginner? my LookAtMouse Script don't work😅

[austere jewel]

Stop cross-posting, I've told you this already. Just repost your question in the one channel after a reasonable amount of time has passed.

[peak plover]

i didn't know that this was cross-posting, i only wanted to find someone who knows the answer

[hallow cove]

ok so, I need my list of types to look like this

however it looks like this currently

and it's not that it's not sorted, that's not why they don't show up

Type[] types = a.GetExportedTypes();```

this is my current way of getting the types

also the first example I showed also has stuff like data types

I'm basically just trying to make a way to define variables in my visual script editor

[flint sage]

float[] isn't really a type

[hallow cove]

yeah I don't know the terms for many of these things

my end goal is to get a list of stuff like this

so I can display them in the inspector

and then drag them in the graph view that I have as an instance

[flint sage]

https://docs.microsoft.com/en-us/dotnet/api/system.type.makearraytype?view=net-6.0

You probably want to use this to create arrays of the list of types that you have

[hallow cove]

yeah I still don't know how I would get a list like that, where I can define floats, ints, and also references to components

[flint sage]

Which bit specifically? I don't know how that scripting solution works

[hallow cove]

what do you mean?

firstly, the example I want to copy looks like this for the Types category

mine doesn't contain like half of these, no animator

no animation type

idk why they're missing

[sage radish]

Not all Unity types are in the Core assembly, where UnityEngine.Object is. It's split into modules.

[hallow cove]

how would I change the script then?

it's pretty new stuff to me

[novel plinth]

like huge chunks of those are internals

[sage radish]

You have to combine all the types from all the Unity assemblies, but also filter out internal/inaccessible types.

[flint sage]

If you want to get all types then you can use AppDomain.CurrentDomain.GetAssemblies() to get all Assemblies, then you can use that to get all types

[hallow cove]

Assembly a = typeof(UnityEngine.Animation).Assembly;

I see what my problem was

[flint sage]

To get the array types you use this

[hallow cove]

doesn't this work tho?

Type[] types = assembly.GetExportedTypes();

[flint sage]

I'm not aware of that method

If it gives teh result you want then great

[hallow cove]

nope it gives an error

the thing is

I want stuff from under the UnityEngine namespace

and not everything

and not just the core as previously stated

again I'm sorry for asking so much but I really have no idea what I'm doing 💀

[flint sage]

See this

[hallow cove]

oh ok uhh

I added this

                continue;```

it's hacky but it gave the result-

let's see if it really works tho

well, I get this error from my method that tries to get an icon corresponding to a type:

UnityEditor.AssetPreview.GetMiniTypeThumbnail```

[flint sage]

Well yeah, not all types are supported

Or you're passing a null value

[hallow cove]

Texture icon = EditorGUIUtility.ObjectContent(null, type).image;

I just followed unity's example

[flint sage]

Again, probably does not work for all types

[hallow cove]

yeah but how in the hell would I check for that

if is not object?

that's what it's asking for the in the parantheses

[flint sage]

Check the reference source probably or call AssetPreview.GetMiniTypeThumbnail yourself and check if the return value is null

[hallow cove]

still returns an error

        return null;```

try catch maybe

[flint sage]

Out of luck, go figure out what the source does and change your code to adjust

[hallow cove]

ok that worked

[flint sage]

Catching a few thousand exceptions will probably be quite slow and you should consider figuring out why it's failing instead of putting bandaid on it

[hallow cove]

I can see

I will do that after I fix a small bug

I also still need to add umm

floats, ints, strings etc.

[hallow cove]

ok I'm back and I have one last problem, I see a lot of types that seem to be linked

there's a lot of NavMesh types for instance, and the search window is slow right now due to the sheer amount of objects in the list

I would like to group them, but I genuinely have no idea how

[flint sage]

Looks like it might be grouping based on namespace

[hallow cove]

no that's

that's me taking every type and making a group for that

and then adding the type and it's methods inside of the group

I just wish I knew how to group up let's say, all the NavMesh related items

[flint sage]

Well a part of those might be in unityengine.navigation

Not all though

There's no magic way

[hallow cove]

oh yeah

ok yeah that did not go as planned, it worked, but then I realized that the assembly names were confusing

anyways, thanks for the help!!

[sudden granite]

@hallow cove maybe you can make use of null conditional operators to simplify your null checks https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/operators/member-access-operators#null-conditional-operators--and-

[hallow cove]

oh yeah right

I forgot those existed

thanks a lot!

I will try them

currently the try catch system is very slow

[sudden granite]

yeah exception handling is extremely allocation heavy / the CLR does a lot of nonsense when it happens

[undone coral]

there is an extract stack trace method unity provides in order to reduce allocations

[sudden granite]

hmmm not able to find that - are you talking about Environment.StackTrace?

ah

UnityEngine.StackTraceUtility.ExtractStackTrace()

[tough knoll]

I has question

I have a special runtime property system

Each property object can have another property object as a parent

This is so that individual actors in the game can share some definitions (i.e all flying actors have some of the same properties)

Since properties are stored in dictionaries, this means accessing a property involves one dict lookup per "layer" of parenting

I wrote a quick class to cache a reference to a property conveniently, but I can't create the object in the field initializer since the properties are created when the owner object's init function is called some time after creation ( have to set it up and set it's type and data block etc.)

I've been using this pattern to declare cached properties conveniently:

    public float fixedHeight {
        get {
            if( m_PropertyFixedHeight == null ) {
                if( data == null ) m_PropertyFixedHeight = new Moros.CachedPropertyFloat( Moros.ProjectSettings.thingPropertyDefaults, "fixedHeight", true );
                else m_PropertyFixedHeight = new Moros.CachedPropertyFloat( properties, "fixedHeight", true );
            }
            return m_PropertyFixedHeight.value;
        }
        set {
            if( m_PropertyFixedHeight == null ) {
                if( data == null ) m_PropertyFixedHeight = new Moros.CachedPropertyFloat( Moros.ProjectSettings.thingPropertyDefaults, "fixedHeight", true );
                else m_PropertyFixedHeight = new Moros.CachedPropertyFloat( properties, "fixedHeight", true );
            }
            m_PropertyFixedHeight.value = value;
        }
    }```

While it totally works fine, it's extremely verbose and takes up shit tons of space at the top of my files. For something like this I would use a preprocessor macro but C# has no such thing ofc. Can anyone think of a better pattern for it?

[dusky carbon]

disregard this, probably not possible in unity

[tough knoll]

Wow

[undone coral]

does anyone know why

ID3D11ShaderResourceView* (UNITY_INTERFACE_API * SRVFromNativeTexture)(UnityTextureID texture);

is cursed?

[tough knoll]

Wouldn't making everything an extendo object have some serious performance implications

I've never used this feature but it seems like the nuclear option

The preprocessor idea was because it's free, right

I know the C# property wrapper isn't "free", but it's pretty close

[light citrus]

//Declara o que é o Struct Transições
public struct Transicao_Struct
{
public Transiction_Scr scrTransicao;
public string strState;
}

//Declara o que é o Struct Estados
[System.Serializable]
private struct Estados_Struct
{
    public Transicao_Struct transicoes;
}
//Declaração do Struct
[SerializeField] private Estados_Struct[] structEstados_ = new Estados_Struct[5];

does anyone knows how to make so that the Transicao_Struct appears inside the Estados_Struct?

[hollow garden]

make it serializable

[light citrus]

the following is the only thing that appears and I don't wanna have to make two arrays for that because it looks ugly on the inspector

[light citrus]

already tried

[hollow garden]

well it has to be serializable for it to be serialized, obviously

[light citrus]

yep, did that, didn't work

[tough knoll]

is Transiction_Scr also serializable

[hollow garden]

so it did nothing? define didn't work

[sly grove]

you did what?

[light citrus]

yes

[sly grove]

Right now Transicao_Struct is missing [Serializable]

[light citrus]

put serializable in the struct

[sly grove]

try again

it's not going to work without it

[dusky carbon]

also what is Transiction_Scr, is that serializable?

[light citrus]

//Declara o que é o Struct Transições
[SerializeField] public struct Transicao_Struct
{
public Transiction_Scr scrTransicao;
public string strState;
}

//Declara o que é o Struct Estados
[System.Serializable]
private struct Estados_Struct
{
    [SerializeField] public Transicao_Struct transicoes;
}
//Declaração do Struct
[SerializeField] private Estados_Struct[] structEstados_ = new Estados_Struct[5];

[tough knoll]

☝️

[hollow garden]

you did serializefield...

not serializable

[sly grove]

this is not the right attribute

[tough knoll]

aaargh

[light citrus]

changed nothing

[sly grove]

[Serializable]

not SerializeField

[tough knoll]

BUT MY ACTUALLY ADVANCED CODE PROBLEM

[light citrus]

anhhh

thanks

[hollow garden]

not advanced btw

more like general imo

[light citrus]

Thank you guys for the help, It worked

[dusky carbon]

@tough knoll so my idea from earlier should work if you somehow get postsharp working with the compiler used for unity, searching around I see some people finding success with that. In any case it shouldn't affect runtime performance because the interception should modify the actual generated code

[tough knoll]

I'm kind of not super into that idea because it would involve additional setup for other contributors if they want to use my codebase. I'm trying to make this framework for public use, so ideally it would have to be plug and play with unity

I also considered writing my own pre-processor but for same reason as above, since people don't expect preprocessor macros in C# I thought it might be confusing

I guess I could write an editor script to automagically setup postsharp but still

[dusky carbon]

https://blog.postsharp.net/post/thinking-beyond-roslyn-source-generators-and-aspect-oriented-programming.html

unity uses roslyn right? this suggests there is something built in that it supports for source generation

[flint sage]

afaik not supported/well integrated yet

[tough knoll]

This is interesting though

reading now

I might be misunderstanding this, but it being additive only would mean that I couldn't use it to invisibly create those property wrappers since they have to be accessed by the code before compile time, right?

[dusky carbon]

it should just mean that it can't override getters/setters that you define. (so as long as the user doesn't specify getters/setters when using your attribute it should be fine)

[tough knoll]

ah

Okay

Yeah their example looks like exactly what I'm after

The fact that you declare fields instead of properties is even more what I want. I want like... float SomeFloat { // Totally a float and not pointer to a property's backing field, I swear }

[torpid pebble]

Does anyone here have any experience using the BigQuery API (installed via Nuget) in their game? I got it to work, but it crashes whenever I try and build the game via WebGL.

PLZ how to modify vertex data, from mesh data array, that can have different data layout (no normals or have uv2 in different meshes) ?
without using streams(i have only stream 0) and without structs(may have big number of layout variants)

[sage radish]

The user would still have to define all their classes as partial. @tough knoll Unity has an undocumented way to programmatically modify code called IL Post Processing. Some Unity packages use it, like Entities and Burst, but Mirror also uses it for SyncVars, which is precisely converting fields into properties.

[tough knoll]

!!!

Docs??

Cant find on google

I'm in the midst of reading through source generators and it's like... Okay, must create external assembly, with associated XML files, then I have to create another XML file for the project, rulesets, create labeled files in unity... all for a measy #macro

Seems goofy that they're now looking into preprocessors after finally realizing that they have some use cases but they have to do it in the most oblique manner possible instead of just giving us macros

[hollow garden]

undocumented way
proceeds to ask for docs

[sage radish]

A bit of information here, but best way is to just check how Unity's packages, like Unity.Entities, use it

[regal olive]

i think i am onto something, cause i really dont understand whats going on. so in a function, i am checking if(inv.DragSlot.item.name == slot.slot.item.name)
i am getting NullReference on slot.slot.item.name i thought weird, maybe didnt initialize item correctly. But that aint it. when i check manually, the string is there and i even did a Debug.Log() with the context arg checking slot.slot.item since slot.slot.item.name gives Null like i said. can anybody PLEASE help me, this is really getting frustrating

[regal olive]

Please i need help

[humble loom]

Set a breakpoint and check the values in situ

[dusky carbon]

I think he figured it out a long time ago in a code-general cross post

[grave bear]

Mono.CecilX is a fork of Mono.Cecil right? any particular reason to use Mono.CecilX?

[vast bronze]

I don't know if this is the right place to ask this but is it possible to set up Visual Scripting to make NetworkBehaviors? or is it strictly only able to create MonoBehaviors

specifically with Netcode for Gameobjects

i wasn't sure whether this belongs in #archived-networking or here

[thin mesa]

probably. you're better off asking where people are more familiar with visual scripting though #763499475641172029

[vast bronze]

oh im blind

thank you

[tough knoll]

true

To my defense, I was literally getting dressed heading out the door reading your message

[tough knoll]

Man

This seems like it but it's gonna be some archeology hours if I have to copy from the packages\

;__;

[hallow cove]

I'm still having the same issue with getting icons for types

whenever I try this with some Types: icon = AssetPreview.GetMiniTypeThumbnail(type);

it gives me this exception: System.NullReferenceException: Object reference not set to an instance of an object

and I have no idea how to fix this without a try catch

[hallow cove]

this is how I solved the bug

      return null;```

C# is truly a masterpiece

[austere jewel]

you have a type named T?

[novel plinth]

I think he meant, the literal type <T> Lol.. just noticed it wasn't the case, he checked the type with string 👀

pretty sure you got type mismatch, bcos GetMiniTypeThumbnail will return the thumbnail IF you put the correct type in the parameter, otherwise it will return null
