whats in the list?

foreach(var go in list)
  GameObject.Destroy(go);

[wispy epoch]

So i feel kinda dumb because i couldnt figure out how to implement that list idea with each game object and then manipulate them. Seemed complicated but now this explanation is making me think thats the only way. What i did was make separate functions for each of the 4 references i needed individually and set them in the singleton so i could call them. It seemed to work as i can again see the references in the editor on scene reload

[plucky laurel]

let move to #archived-code-general

code

[maiden turtle]

async Task Start() swallows exceptions? How do I make the engine await the task?

[plucky laurel]

that is insufficient to help you

[orchid hinge]

what should I add

[maiden turtle]

I saw async void Start() and kind of giggled at that, because I know it won't work, but async Task Start() does not work either?

[undone coral]

imo declaring async unity callbacks works poorly

[orchid hinge]

I have a problem, after instantiating a gameobject I cannot access jagged arrays for some reason. The arrays are created in the same script. It throws out a nullreference exception.
https://gdl.space/felegasuda.cs

[undone coral]

@maiden turtle use unitask, and do

void Start() {
 UniTask.Void(async () => { ... });
}

same as

void Start() {
 InnerStart().Forget()
}
async UniTaskVoid InnerStart() {
 ...
}

unity's default async execution context is bad

and the rules for how it treats Start, OnEnable, etc. when they're declare async are fuzzily defined

[devout hare]

It says neurons is null
so we need to see where you define and create neurons

[orchid hinge]

ok

[maiden turtle]

Ok thanks

[orchid hinge]

but like its fine when I try to call it on a different line in the script

[orchid hinge]

The size of the jagged array is supposed to be set in this function, sorry the thing that I posted first didnt make sense new link that has a similar error https://gdl.space/rowuciyefo.cs

public float[][] neurons; this is in neuralNetwork

[devout hare]

ok, where do you create the array?

[orchid hinge]

here

[devout hare]

that defines a variable

where do you put an array into it?

[undone coral]

not sure how that's possible. it should work fine with git

[orchid hinge]

in initialize

https://gdl.space/rowuciyefo.cs line 6

[devout hare]

Not in that code you do

[orchid hinge]

?

[azure hinge]

I found out! Sorry! It was happening because the teammate that pulled didn't setup the addressables correctly

like not clicking the GenerateDefaults button lol

[undone coral]

yeah

[orchid hinge]

I create the sizes of the array here

[undone coral]

it sounds like you guys are not using git right now

[azure hinge]

we are using perforce... I hate it btw lol

[devout hare]

You create the sizes of the inner array (neurons[i])

you need to create neurons as well

[orchid hinge]

ok found the error sorry

[undone coral]

you can't use sizeof on a Vector3. users who want to manipulate raw memory, for the most part, of .net types should use the Marshal functions

[final steeple]

No, quite the opposite actually

You should avoid Marshal when you can

You can sizeof a Vector3, it just requires unsafe context

Or you can use Unsafe.SizeOf which does the same thing

[orchid hinge]

I forgot to move it initalli I had it in start and moved everything else and forgot this tysm for the help

[final steeple]

Marshal.SizeOf will give you the marshalled size which is different

[devout hare]

👍 #💻┃code-beginner next time

[orchid hinge]

idk I thought it was some sort of weird error also ppl were talking there so I didnt want to annoy them

in code general too

[final steeple]

I'd elaborate further but I'm on mobile currently so typing it all out would be hell -- but know that this guidance comes from Microsoft developers working on .NET itself

Much of Marshal is essentially "legacy" as far as modern code should be concerned

[plucky laurel]

(like whole unity .net)

[undone coral]

yeah definitely.

[flint sage]

That contradicts what Zombie mentioned that it doesn't

[final steeple]

This is very close to what is done yeah

It doesn't use much extra storage because of how and what we encode

We only need a single component per pixel, not full rgb

Because the color is defined by the light

[flint sage]

Yeah that's the only thing I could think of

[final steeple]

Really though that's the easy part -- the hard part is actually generating those lightmaps to begin with

[flint sage]

Oh yeah

[final steeple]

You need to do a lot of "deconstruction" on the textures

[flint sage]

I don't even watn to get into that 😛

[plucky laurel]

@final steeple you are making a lightmapper?

[final steeple]

Not quite a lightmapper, just a system built on top of Unity's lightmappers

We can use enlighten, progressive, etc as a base

And we process their output into data that we use

[plucky laurel]

i see, waiting for someone to make runtime lightmapper

[undone coral]

(1) use [RuntimeInitializeOnLoad]. declare a private constructor. the rest you can fill in it. that's it.
(2) it sounds like you want to add an attribute to something. it's better to have the something strongly reference your code and invoke it every frame. otherwise, i suppose a regular list of weak references.

[flint sage]

There's a few

[plucky laurel]

i only seen native libs

[flint sage]

I guess they might've quit after SRP

[undone coral]

@proven thorn DOTS doesn't really work, so i wouldn't recommend trying to build a game on top of it right now

[final steeple]

And if you aren't using DOTS, I have a guide on how to write a proper (imo) singleton for MonoBehaviours

[plucky laurel]

runtime lightmapper, something simple Q1/3 style, for retro shooters, imagine that

[final steeple]

#archived-unitytips message

[final steeple]

I've looked into it -- for one of the games I work on we support loading Quake and Half-Life BSP, including lightmaps

[undone coral]

the hardest part is computing the lightmaps at runtime. shipping a whole renderer for your game, then dealing with all of that, is a lot

[final steeple]

So in theory if you wanted to do lightmapping at runtime you could run the BSP lightmapping tools externally

And then reload the map

[undone coral]

yeah. i would ship blender, round trip the geometry with FBX

[final steeple]

Blender might be a bit heavyweight but it's a step in the right direction yeah

[undone coral]

i don't know if it supports the cinema light remapping workflows

for baking

[final steeple]

I imagine the biggest problem might be licensing

[undone coral]

nobody does that stuff

[final steeple]

Blender is GPL iirc

Though I suppose it depends on how you integrate it

[regal olive]

how to do weighted generation again? (with a ten percent chance, generate this)
and how do i do it with multiple outcomes? i know i could just generate a number between 0 and 1 and do the rest but what if i had for example:
outcome 1: 15% chance
outcome 2: 20% chance
outcome 3: 30% chance
outcome 4: 35% chance

[plucky laurel]

yeah blender as a dependency is a no no. there are libs for unwrapping, there is a foss native lightmapper, ive looked at it occasionally trying to picture if its viable

it all seems viable, but i would not be able to maintain any of that unless i wrote it

[final steeple]

It's certainly doable, just gotta weigh whether it's worth the effort

A fully featured lightmapper is a ton of work

Especially if you support hardware acceleration for it (which you should if you plan on doing this at runtime)

[plucky laurel]

yeah its kinda, if you do it, youd go for retro shooters for good, several titles on that tech.

i dont think youd need that much effort put into optimization and acceleration, as low res lightmaps would suffice

[final steeple]

We're planning on open sourcing the game we support BSP in (Dusk) under MIT so eventually more games can leverage that for modding

I kinda went a bit overboard lol, it supports a ton of variants of BSP

Source, Quake, Quake 2, Quake 3, GoldSrc, etc

Along with all the various variants per game

[plucky laurel]

have you seen Prodeus level editor?

[final steeple]

Yeah

[plucky laurel]

not brushes, but still, its kinda the ideal variant, integrated editing

[final steeple]

It's stored as brushes sort of

The map format is similar to Quake in that it's a text format set of brushes and stuff which later gets compiled into a bunch of meshes and other data

[plucky laurel]

in prodeus?

[final steeple]

Yeah

I looked into it a while back

[plucky laurel]

oh i mean its not really csg

[final steeple]

I don't mean the editor I mean the format it saves to

[plucky laurel]

ok

have you seen Poseidon asset?

[final steeple]

That I haven't

[plucky laurel]

its a first time i saw something like that, they do csg with actual meshes as brushes. Directly build levels with meshes, with all the materials etc, all csg

[solid elm]

I want to call the overriden CalculateAccuracy() method of class FlickNormalScoreSystem, parent class ScoreSystem in child class FlickNormalWeaponManager of parent class WeaponManager.

FlickNormalWeaponManager.cs

public class FlickNormalWeaponManager : WeaponManager {
private FlickNormalScoreSystem flickNormalScoreSystem;

private void Awake() {
flickNormalScoreSystem = scoreSystem.gameObject.GetComponent<FlickNormalScoreSystem>();
}

private void Start() {
flickNormalScoreSystem = scoreSystem.gameObject.GetComponent<FlickNormalScoreSystem>();
}

protected override void GunShotLogic() {
flickNormalScoreSystem.CalculateAccuracy();
}
}

FlickNormalScoreSystem.cs

public class FlickNormalScoreSystem : ScoreSystem {
public override void CalculateAccuracy() {
//logic code
}
}

• if i use the awake function it is straight giving error of null object reference.
• if i use the start function it gives same error on flickNormalScoreSystem.CalculateAccuracy() method call.

[unkempt nova]

Parent class? Child class? Am I losing it, or are these not related at all?

[fresh salmon]

Yeah

The issue isn't related to inheritance

[solid elm]

its structured

[undone coral]

#💻┃code-beginner try starting with a unity tutorial or programming tutorial, i like ray wenderlich's!

[fresh salmon]

The GetComponents didn't find so they returned null

[undone coral]

it's telling you what the error is: there's a null object reference

[unkempt nova]

If you just tried pasting, it was too big

#854851968446365696

[solid elm]

its not null i checked with null and debug log

it is just giving error on function call

[fresh salmon]

Post the stack trace

[solid elm]

how we dot that O_O

[unkempt nova]

This just sounds like a race condition problem to me. Trying to load something else in another script before it had a chance to get it. Also, this should be in #💻┃code-beginner

[fresh salmon]

Oh yeah you defo picked the wrong channel to ask in

[solid elm]

i already ordered the script

[unkempt nova]

Ordered?

[solid elm]

script execution order

[unkempt nova]

Oh

[fresh salmon]

Post the stack trace. It's what's under the NullReferenceException error message, it points to where execution was when the error happened

[solid elm]

its only monobehaviour class giving error if i use non monobehavior class without inheritance than there is no error

[undone coral]

is there a pre-existing prometheus exporter / structured performance format for unity runtime?

[solid elm]

talking about FlickNormaScoreSystem Class if i inherit the class from score system thant it gives null ref error else it works fine without monobehaviour

[fresh salmon]

Sample stack trace

System.NullReferenceException: Object reference not set to an instance of an object.
   at Program.Main()

Points to Main method in my Program class, for my case. You'll have more lines like these with more information, such as line numbers

using Awake()

[fresh salmon]

Okay, so it happens on FlickNormalWeaponManager.cs line 11

Post what's on that line

[solid elm]

NullReferenceException: Object reference not set to an instance of an object
FlickNormalWeaponManager.GunShotLogic () (at Assets/Scripts/Tasks/Flick Normal/FlickNormalWeaponManager.cs:40)
FlickNormalWeaponManager.Update () (at Assets/Scripts/Tasks/Flick Normal/FlickNormalWeaponManager.cs:23)

using start()

[solid elm]

flickNormalScoreSystem = scoreSystem.gameObject.GetComponent<FlickNormalScoreSystem>();

[fresh salmon]

Okay so scoreSystem was null

[solid elm]

its present in parent class working fine why null ? null during awake call ?

[fresh salmon]

How is it retrieved, ie. where do you assign a value to scoreSystem?

[solid elm]

Weapon manager Class parent of FlickNormalWeaponManage class

[fresh salmon]

Yeah I got that, but where do you put a value into that variable

[solid elm]

value ? you mean reference or logic for score system

[fresh salmon]

I mean where are you doing scoreSystem = something something;

If you're ever doing it

[solid elm]

its used in both parent and child classes

for calculations

[fresh salmon]

I'm not asking where it's used I'm asking where it's assigned a value

[solid elm]

bro its called referenced

XD

in the parent class

weapon manager

[fresh salmon]

No, it's called an assignment, when you do x = y, you assign x
And inheritance has nothing to do with whether the variables are assigned or not

It can still be in the parent class, unassigned

[solid elm]

scoreSystem = GameObject.FindGameObjectWithTag("ScoreSystem").GetComponent<ScoreSystem>();

Parent class

[fresh salmon]

Theeere we go

Is that in Awake?

[solid elm]

yes

[fresh salmon]

Is Awake overriden in the child class? If yes are there measures in place to run the parent's Awake, with virtual and override?

[solid elm]

no awake is not overriden should i override ?

in child class

[fresh salmon]

No that's good

[fresh salmon]

So after that line ^^^ put Debug.Assert(scoreSystem != null);, play the game and watch out for "Assertion Failed" errors

[solid elm]

if i use a non monobehavior class in FlickNormalWeaponManager, like FlickNormalScoreSystem flickNormalScoreSystem = new FlickNormalScoreSystem();

there are no errors

[solid elm]

ok trying

[fresh salmon]

Wait you're using new on MonoBehaviours?

That's not allowed

[solid elm]

no i am not

i just tested

[fresh salmon]

Alright

[solid elm]

scoreSystem = GameObject.FindGameObjectWithTag("ScoreSystem").GetComponent<ScoreSystem>();
        Debug.Assert(scoreSystem != null);

like this

[fresh salmon]

Yep

For good measures you would also want to check that this code is running at all, by doing a Debug.Log above those two lines

[solid elm]

its giving error on scene load

NullReferenceException: Object reference not set to an instance of an object
FlickNormalWeaponManager.Awake () (at Assets/Scripts/Tasks/Flick Normal/FlickNormalWeaponManager.cs:11)
UnityEngine.GameObject:AddComponent()
GameManager:<SetupGameEnviornment>g__SetupFlickNormalTask|16_0() (at Assets/Scripts/Game Manager/GameManager.cs:88)
GameManager:SetupGameEnviornment() (at Assets/Scripts/Game Manager/GameManager.cs:76)
GameManager:Start() (at Assets/Scripts/Game Manager/GameManager.cs:46)

is score system not referenced or what ?

[fresh salmon]

So the code on that line 11 is ran before the parent's Awake is executed

Or Awake isn't executed

[solid elm]

child class awake ran first ?

[fresh salmon]

You told me you didn't have Awake on the child class
First, make sure your code that finds the ScoreSystem runs

[solid elm]

parent class WeaponManager have object of score system referenced in awake, child class FlickNormalWeaponManager have object of flickNormalScoreSystem refrencing in awke via score system

i posted code 😦

[solid elm]

can't find why score system is null in parent

😦

[fresh salmon]

So both of them have Awake methods, the problem is that if you have the child class attached to an object then the child class's Awake will run, not the parent's

Check that this is the case by logging something in both Awakes

[solid elm]

ohh

logging which runs first

[tough tulip]

only the child will run unless you override a virtual method and call the virtual method from the overridden method

[fresh salmon]

Yep exactly

[solid elm]

bro child one runs first

😦

that's the prob

so should i make override function and call it in parent's awake

[fresh salmon]

So make the parent Awake virtual, the child an override and in the child call the base implementation base.Awake();

[solid elm]

bro that's all

thanks 🙂

but is awake overriden available ?

[fresh salmon]

As the base class' Awake is virtual yep

[solid elm]

thanks bro, one thing i learned i need to revise the oops principles xD

if i have an object that could be an int, long, etc - number value type - how can i easily cast it to a double and also know it was a number type?
e.g.

if (value is asDouble double) {
  
}

will this be false for an int (because it's not a double) or true (desired, because I want to cast it to a double anyway)

essentially, is there a version of Convert.ToDouble(value) that does not throw exceptions

it just expands to if (blah is int X) if Blah is float Y...

[pine tulip]

can some one help me

[fresh salmon]

You're being helped in #archived-code-general

Do not cross-post.

[pine tulip]

ok

[gray pulsar]

Is the as operator not what you want? https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/operators/type-testing-and-cast#as-operator

[undone coral]

it's unclear if it actually does the conversion

[gray pulsar]

It does. It's as explicit cast

[undone coral]

so value as double? - is it null when value is an int? @gray pulsar

do you see why this is tricky

it's not bad to write the switch statement

i was just wondering if it already exists

[gray pulsar]

It shouldn't be null in this case, since the cast operation from int to double exists

[undone coral]

is that how as works? the cast is defined for explicit casts

and it's not clear to me if as is an explicit cast

it's definitely not defined for a nullable type

[frozen imp]

Once you determine its type you would be able to cast it

It must be a manual process though.

The is, as, and typeof operators cannot be overloaded.

A user-defined type can't overload the () operator, but can define custom type conversions that can be performed by a cast expression. For more information, see User-defined conversion operators.```

[undone coral]

public class Program

    public static void Main()
    {

        var y = x as double?;
        Console.WriteLine(y.HasValue);
    }
}

prints False @gray pulsar

[frozen imp]

You have to (double)x it I think

[undone coral]

then i wouldn't know if the conversion failed or if the value was 0

[fresh salmon]

You would get an exception in the face

It did for me

[undone coral]

https://dotnetfiddle.net/GMS67G correctly shows 3

[undone coral]

i'm trying to avoid throwing an exception

i suspect there must be a way to do this

in this example i can't tell the difference between a real NaN

[frozen imp]

I mean you should detect its type and cast it accordingly, I think?

[undone coral]

but it's easy

yes, that's what i'm doing in this example

i'm wondering if there is already a C# shorthand for this, and it sounds like there is not.

[undone coral]

actually

using System;
                    
public class Program
{
    public static void Main()
    {
        object x = (int)3;
        var y = (double)x;
        Console.WriteLine(y);
    }
}

doesn't work ever.

[fresh salmon]

There isn't yet. .NET7 (preview) has generic math and the INumber interface. Set to release next November, maybe in Unity in 10 years :)

[gray pulsar]

I am proved wrong. Good to know

[fresh salmon]

This could be disgusting but could you do something like this?

object x = // your number
if (double.TryParse(x.ToString(), out double num))
{
  Debug.Log(num);
}

Never do string parsing without specifying culture settings

You should be passing CultureInfo.InvariantCulture to ensure consistent results

Otherwise things will break very easily once the code runs on a system with a different locale

anyone know how to use TcpClient to host a local websocket a website can connect to?

ideally i'd like to connect to ws://localhost, but no examples i've found online work without a port

[fresh salmon]

There's TcpListener which acts like a "server", though for websockets you'll have to handle the handshake and decrypting/encrypting protocol yourself
That page has the resources to set up a basic one https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_server
And there's still the WS specs (https://datatracker.ietf.org/doc/html/rfc6455) if you want the raw thing

There are also assets available as NuGet packages that do it all for you, if you want to host the server outside of Unity as a console app or Windows service for example

[raw schooner]

so, i'm having the issue that var client = server.AcceptTcpClient(); never completes

i'm guessing there has to be some connection already open or something like that?

[fresh salmon]

If the server is not running on the same computer check the firewall settings, otherwise check the URL+port number on both sides

[raw schooner]

no i mean, i'm doing this

using System.Net;
using System.Net.Sockets;

var server = new TcpListener(IPAddress.Parse("127.0.0.1"), 80);
server.Start();

var client = server.AcceptTcpClient();

Console.WriteLine("Connected.");

Connected. never prints

oh, nope, you're right

alright sick, thanks

so, i'm trying to send a simple string to the connecting website (it's a command that's supposed to execute some stuff). i know the command works, however, using the following code doesn't have any effect on the website;

using var writer = new StreamWriter(client.GetStream());
writer.Write("start");

what do i need to do instead?

using var stream = client.GetStream();
var bytes = Encoding.ASCII.GetBytes("start");
stream.Write(bytes, 0, bytes.Length);

this also doesn't appear to work

There is a class with byte array field inside (2d or 3d does not matter). The values can change from outside the class Update(indices,newValue)
When setting some elements of the array to specific values, another method should be called as well to generate a new mesh based on the updated array.
Therefore, for some values, updating the array is enough but for specific values, in addition to updating the array, another method should be called to regenerate the mesh.
Defining a bool variable (dirty flag) and SetDirty is the right approach, right?

   _chunkObject.Update(indices,newValue);

   // call _chunkObject.GenerateMesh in the right place after all chunks are ready

// Chunk object class
public class ChunkObject{
    public void Update(Vector3Int[] indices, byte newValue){
       _chunk.Update(indices, newValue); // update the array
       // set shouldUpdateMesh based on newValue
       if(shouldUpdateMesh){
          IsDirty = true;
          UpdateMesh(); // only calculates triangles and vertices but not generate mesh
       }
    }
    public void GenerateMesh(){
      if(IsDirty){

Hi everyone. I am making a custom build process for Android that needs to use .aab and Split Application Binary (OBB) and other preprocesses.

i have problems with my canvas scaler. it is set to scale with screensize, but if i change res (first pic) the images on the bottom left are getting displayed wrong. on original res (second pic) they are displayed right. could be an issue with my code, because the squares are getting instantiated
they have a parent, are getting instantiated like this:

curr = Instantiate(endRoom, parent: roomParent, position: new Vector3(room.x * 30 + xOffset, room.y * 30 + yOffset, 0), rotation: new Quaternion());

where xOffset is the space from the screen, room.x and room.y are just coordinates in a double nested list, 30 is the meant spacing between them.

^^ it seems to ignore that *30 ? i tried to set the positions manually, and when they align like they should (n * 30) it works, but they arent aligned that way, either the canvas scaler moves them or idk

instead of 30 (1366:768) it moves 63.6335 (16:9)

I assume SeedSlot is a class, in which case every entry of your array is actually the same object (see line 94)

Hey, i want to make my own backend and currently i search for best-practices to get data in my online game.
Basically: i use Photon Networking and dont have access or did anything to the server so i just handle all the clients.

I would need to get Data from a MongoDB and would like to also use Redis (Pub/Sub mostly for live updates). Is it a good practice to make a connection on each client to these databases or is it way better idea to make my own RESTful Service which then calls the internal functions and give back the result?
I am not sure about connecting from the client to MongoDB for example, because i feel bad that someone can decompile the game (idk how) and get the password and do their own changes in the database

[flint sage]

Never connect straight to your database from your user facing application

[drifting escarp]

Okay thx, most people i found say there is no problem but i was not sure about it 😄

Then i do a wrapper service in between them 🙂

[flint sage]

Anything on the client side should be considered compromised

Any credentials your store there are compromised

If those credentials allow them to modify your database then that's terrible design

[lucid girder]

Yes. Set up a (or multiple) back-end that connects DBs and other APIs which it needs, and let the client send and recieve data to and from the back-end. That way you can also manipulate what needs to be sent. Say you fetch a huge list from a DB, but the client only needs a few entries, you do that on the back-end and only send the required data back to the client. Also remember to cache often used resources (like that huge list).

Also also, if there the client needs to have login credentials: remember to hash, encrypt, etc etc, before sending it to your back-end. And don't save it in plain text. Safety/Security is key!

[drifting escarp]

[fresh basalt]

Any ideas why RigidBody2D.cast doesn't hit anything? The direction is correct, tried printing it, increased the distance, nothing works
both the player and the ground have box colliders

[flint sage]

You need to use the 3d equivalent to hit box colliders

[fresh basalt]

ill change to tilemap colliders then

@fresh salmon I got my tcpclient to connect and do the handshake. I can connect successfully now. However, disconnecting via the target website (there's simply a Disconnect button, which calls WebSocket.close()) doesn't appear to work.
Disconnecting sends a (what I assume to be) encoded message, but decoding it results in a message length of 0 (bytes[1] is 128). Is there another way to find out whether I'm supposed to disconnect the client?

Perhaps additionally, is there a better way to handle receiving messages besides checking the _tcpClient.Available property in an infinite loop?

[fresh salmon]

I think that trying to read the stream client-side when the server closed the connection results in an exception

Or, you could send a custom message that indicates "I'm about to end the connection!"

[raw schooner]

I tried using _tcpClient.Connected and _networkStream.CanRead, both of which remain true when I click disconnect

I'm not in control of the website, sadly

[cedar ledge]

does the general advise of not using null coalescing and such with Unity.Object apply to this situation?

using UnityEngine;

public class BGMusicManager : MonoBehaviour
{
    AudioClip bgMusicClip;
    AudioSource bgMusicSource;

    private void Awake()
    {
        bgMusicClip = GetComponent<AudioClip>() ?? throw new MissingReferenceException($"Missing {typeof(AudioClip).Name}");
        bgMusicSource = GetComponent<AudioSource>() ?? throw new MissingComponentException($"Missing {typeof(AudioSource).Name}");
    }

    private void Start()
    {
        bgMusicSource.clip = bgMusicClip;
        bgMusicSource.Play();
    }
}

Correct me if I'm wrong, but I feel like the funkiness around whether it's truly null or destroyed-fake-null is irrelevant during Awake(), no?

[fresh salmon]

I think that can safely be used here yeah. An alternative would be assertions:

Debug.Assert(bgMusicClip != null);

Which takes care of the semi-null shenanigans by using the overloaded operator

[cedar ledge]

interesting. would you recommend that over what I'm doing?

[fresh salmon]

It's less bulky and you have the possibility to pass a custom message as a second arg, so probably yes

[raw schooner]

typeof(AudioClip).Name?

[cedar ledge]

i changed it to nameof(bgMusicClip)

i was just messing around there lol

[raw schooner]

Anyway. Maybe I haven't looked at TcpClient's properties enough yet, but I'm not sure how else I can check whether the target website is attempting to close the connection

As long as my app is running, the connection is open (website remains on Disconnecting... when clicking the button to disconnect). Only once I close my app (i dispose of the stream, then the client, then the listener) does the disconnection finally go through (obviously, since the connection is completely terminated)

[fresh salmon]

Hm apparently yeah the Connected property is unreliable. That question covers it well https://stackoverflow.com/questions/1387459/how-to-check-if-tcpclient-connection-is-closed

[raw schooner]

This feels very expensive to do every loop iteration

[wispy lion]

I don't think that works because GetComponent also gives you a fake null when the component isn't there. At least I don't get an exception and log a "False" with this

private void Awake() {
  Joint j = GetComponent<Joint>() ?? throw new System.Exception("test");
  Debug.Log(ReferenceEquals(GetComponent<Joint>(), null));
}

on a gameobject with no Joint.

[cedar ledge]

thank you!

[fresh salmon]

Gives a fake null if it doesn't exist? What is wrong with them lol

[cedar ledge]

can't wait for them to finish what they're working on so that they can maybe possibly in the future sometime if they feel like it move towards standard dotnet 6 and beyond

their system was written before fancy operators like the elvis operator ??= were added to csharp

[fresh salmon]

Yeah, pretty sure they'll eventually do that sice .NET Framework isn't receiving updates anymore

[cedar ledge]

i decided to experiment with sorcery. any idea why it doesn't throw the error? (the commented out code does throw the error)

[plucky laurel]

@cedar ledge check this

public static class Ext
{
    public static void EnsureComponent<T>(this Component owner, ref T reference) where T : Component
    {
        if (reference)
            return;

        owner.TryGetComponent(out reference);

        if(!reference)
        {
            Debug.LogException(new MissingReferenceException($"Missing {typeof(T).Name}"), owner.gameObject);
        }
    }
}

then

void Awake(){
                this.EnsureComponent(ref source);
                this.EnsureComponent(ref rigidbody);
                this.EnsureComponent(ref light);
}

[cedar ledge]

i have something like that in another project, but it's more for any serialized reference rather than components. we already have the RequireComponent() attribute for ensuring components

[cedar ledge]

i dont think your ref keyword does anything in your example, right?

ref on a reference only matters if you're assigning it to be a different reference

wait nevermind

i see how you're using out reference which is basically that

[fresh salmon]

Ah your loop doesn't run because private fields aren't retrieved by default with Reflection. Instead specify that you want to get all of the fields:

.GetFields(BindingFlags.Instance | BindingFlags.Private | BindingFlags.Public)

[cedar ledge]

zamn

here i was thinking that not specifying would have it grab everything

[fresh salmon]

Got fooled once because of that yeah

[cedar ledge]

lol?

[cedar ledge]

NonPublic*

[fresh salmon]

Oh yep

[plucky laurel]

will exception carry stack trace if not thrown?

[fresh salmon]

Doesn't seem like it, new Exception().StackTrace returns null

[cedar ledge]

i think the throw keyword does the magic

actually it would have to

because catching an exception and rethrowing it is common practice for APIs to hide their irrelevant inner workings

that process "recalculates" the stack trace from that catch block

https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/throw

[plucky laurel]

yeah

makes sense guess you can wrap a call to trygetcomp into a method, throw there, try catch in the caller and log exception without rethrow

refering to what i wrote earlier

[cedar ledge]

should i make my professor grade this code:

var fields = typeof(BGMusicManager).GetFields(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public).Where(f => f.GetCustomAttribute<RequiredReferenceAttribute>() != null).Select(f => (f.Name, Value: f.GetValue(this)));
foreach(var field in fields) if(field.Value == null) throw new MissingReferenceException($"Missing reference to {field.Name}");

-reflection
-linq
-tuple
-misc terrible formatting

[plucky laurel]

hold my beer

            string assemblypath = UnityEditorInternal.InternalEditorUtility.GetEditorAssemblyPath();
            var assembly = System.Reflection.Assembly.LoadFrom(assemblypath);
            var type = assembly.GetType("UnityEditor.SceneHierarchyWindow");
            var hierarchyfield = type.GetField("s_LastInteractedHierarchy", BindingFlags.NonPublic | BindingFlags.Static);
            var hierarchy = hierarchyfield.GetValue(type);
            var hierarchyType = hierarchy.GetType();
            var sceneviewfield = hierarchyType.GetField("m_SceneHierarchy", BindingFlags.NonPublic | BindingFlags.Instance);

            var expandedIdsField = treestate.GetType().GetField("m_ExpandedIDs", BindingFlags.Instance | BindingFlags.NonPublic);
            expandedIdsField.SetValue(treestate, new List<int>());

[cedar ledge]

beer at 7am? nice

honestly the only thing i hate about that is the m_ s_ prefix style

the hardcoded strings are a close second

[fresh salmon]

That, and for me the vars

[raw schooner]

Ugh, explicitly types

For me it's the unnecessary indentation for every line

[plucky laurel]

string assemblypath = UnityEditorInternal.InternalEditorUtility.GetEditorAssemblyPath();
            var assembly = System.Reflection.Assembly.LoadFrom(assemblypath);
            var type = assembly.GetType("UnityEditor.ProjectBrowser");
            var projectbrowserfield = type.GetField("s_LastInteractedProjectBrowser");
            var projectbrowser = projectbrowserfield.GetValue(type);
            var treestatefield = type.GetField("m_AssetTreeState", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
            var treestate = treestatefield.GetValue(projectbrowser);
            var expandedIdsField = treestate.GetType().GetProperty("expandedIDs", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.Public);
            var assetsFolder = AssetDatabase.LoadAssetAtPath("Assets", typeof(UnityEngine.Object));
            UnityEditorInternal.InternalEditorUtility.expandedProjectWindowItems = new int[1] { assetsFolder.GetInstanceID() };
            expandedIdsField.SetValue(treestate, new List<int>() { assetsFolder.GetInstanceID() }, null);
            type.InvokeMember("OnProjectChanged", System.Reflection.BindingFlags.InvokeMethod | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic, null, projectbrowser, null);

[cedar ledge]

it's because it's copied from a method

[plucky laurel]

this took a while to crack

[fresh salmon]

Type implicitly if the type is clearly visible on the right side of the assignment, otherwise explicitly

[raw schooner]

Those don't happen to be the actual Unity internal fields right

[plucky laurel]

they are

[raw schooner]

Actually nevermind, not even possible i think

From the C++ source?

Surely not

[plucky laurel]

no, managed

[cedar ledge]

what's it called where the type is inferred by the variable's name

[plucky laurel]

in generics?

[raw schooner]

Implicit?

[fresh salmon]

Hungarian notation? nValue

[cedar ledge]

that's it

[raw schooner]

Oh, no

[plucky laurel]

ah you mean self describing code or something like that

aah gotcha

f_health, s_name

[cedar ledge]

vars are acceptable imo. i would prefer explicit types and no hungarian notation, but sometimes when you're game programming, you have things like AudioSource, AudioClip, AudioChannel, etc. where it's both difficult and pointless to name things not based on their type

[plucky laurel]

Single_health, Boolean_isAlive

[cedar ledge]

so if you're going to name things around their type anyway might as well var it up

[fresh salmon]

Yeah, just don't do

var x = SomeObscureMethodThatDoesSomething();

[cedar ledge]

i only do that when it's extremely inconsequential what the type of x is

[plucky laurel]

ive seen some machine learning code f, d, di, dx, u, ih ...

[cedar ledge]

graphics code

like shaders

UGH

[plucky laurel]

its dominant when the main thing is algorithm

[cedar ledge]

not only is IDE support utter garbage, but the variable name conventions do NOT help

[plucky laurel]

guess its easily inferred from the context if you know what youre doing

[cedar ledge]

if

[plucky laurel]

well if you work with ml algos, guess its a must you know how math is denoted

[cedar ledge]

speaking of math

any lurkers here ever studied Type Theory?

[plucky laurel]

like, how to type?

yeah i know how to type

[cedar ledge]

no it's like Set Theory or Category Theory. It's a foundational system of logic kind of thing

but Type Theory is a lot friendlier to programmer brains from what i can tell

Haskell and other functional programming concepts basically stem straight from it

[plucky laurel]

not me, never was interested

[fresh salmon]

Me neither, but Lisp has representation like these especially for conditions if ((< x 2) ... )

I find it really weird lol

[cedar ledge]

I don't think I changed anything significant here but now it's not throwing an error for any null fields

var fields = typeof(BGMusicManager)
    .GetFields(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public)
    .Where(f => f.GetCustomAttribute<RequiredReferenceAttribute>() != null)
    .Select(f => (f.Name, f.GetValue(this)));
foreach(var (Name, Value) in fields)
    if(Value == null) throw new MissingReferenceException($"Missing reference to {Name}");

[plucky laurel]

maybe cast Value to Unity.Object?

not sure

[cedar ledge]

wow that actually did the trick

+1 rep

[fresh salmon]

And to top it off convert that to an extension method so you can do this.EnsureReferencesSet() in Awake

[plucky laurel]

also - cache reflection results per type in a dictionary

linq to for loops

the field getter to delegate

yeah basically a map of lists of delegates

[cedar ledge]

ive never done the caching thing, is it just storing the result of the reflection into a variable? just run that in OnValidate()?

why convert linq to for loops?

[plucky laurel]

no you lazily cache it

if its not in a static dictionary - do reflection, create a list of getter delegates

put in a dict, retreive on repeating calls

because linq is slower and allocates

[cedar ledge]

you do this inside the type itself, or in the static extension class?

[plucky laurel]

some global cached data store static class

[cedar ledge]

so the dictionary would be <Type, FieldInfo> or such?

[plucky laurel]

no <Type, Func<object,object>> i think

[fresh salmon]

Yeah lol made that error when I worked on some DB to type mapper, was painfully slow because I was calling Reflection for each row
Caching the stuff sped it up 10 times lmao

[cedar ledge]

if you're only storing a dictionary of type and a func what are you caching?

[fresh salmon]

The GetFields().Where()

This is expensive

[plucky laurel]

yeah i have global TypeStore where i run reflection on all types once, and every relfection util that requires it can access cached version

[cedar ledge]

that returns type IEnumerable<FieldInfo> not a Func<object, object>

[plucky laurel]

only problem that i didnt solve with this approach yet is that ... relfection data is not garbage collected

so every type you ever retreive is there to stay

[plucky laurel]

getters

you can convert field.GetValue into a delegate

[fresh salmon]

Yeah but then you'll be able to loop through that and for each field info put its .GetValue method into the map

[cedar ledge]

oh i see

[plucky laurel]

i have some code for that nearby

[regal olive]

Okay I thought that would be a new instance for each one is there a way to do that?

[cedar ledge]

so you have a type and some field getters. last thing im confused about is how a 1D dictionary can store that. I feel like that would require Dictionary<Type, List<Func<>>>

[plucky laurel]

its for a setter but the approach is the same for getter

var method = (Action<object, object>)dynSetter.CreateDelegate(typeof(Action<object, object>))

Delegate.CreateDelegate basically

[plucky laurel]

yeah list

you can wrap the info into your class with a del, name, whatever else info you need, attribute

[cedar ledge]

is there a way to simply do what ive already got, but put the awake code in the definition of the attribute?

[plucky laurel]

you mean use the attribute as the global static?

yeah makes sense even

[cedar ledge]

[AttributeUsage(AttributeTargets.All, AllowMultiple = false)]
public class RequiredReferenceAttribute : Attribute
{
    private void Awake()
    {
        var fields = typeof(BGMusicManager)
            .GetFields(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Static)
            .Where(f => f.GetCustomAttribute<RequiredReferenceAttribute>() != null)
            .Select(f => (f.Name, f.GetValue(this) as UnityEngine.Object));
        foreach(var (Name, Value) in fields)
            if(Value == null)
                throw new MissingReferenceException($"Missing reference to {Name}");
    }
}

obviously that awake wont run

but you get my point

[plucky laurel]

well kinda, but at the same time, its dirty

attributes are traditionally just storing data

[cedar ledge]

so where do you typically make them do magic?

[plucky laurel]

static utility class

public static class RequiredReferenceCache{
...
}

[cedar ledge]

but i need awake, so i just stick that in a monolithic monobehavior that gets all fields from all types?

[tribal pivot]

Sure you dont need a (static) constructor?

[plucky laurel]

no in awake you just call a method

like that extension method from above

you can also run it in the editor on project change

omitting runtime completely

for even better results move it to a dll

it will then work even if the project fails to compile, so you wont miss anything because of it

now im thinking if project change detects any actual field changes, guess this route will have bunch of edge cases

[sage radish]

Do you want this attribute to only work with the BGMusicManager type?

[cedar ledge]

no

don't worry about it, it's just for fun

i need to focus on getting this assignment done due tomorrow anyway

i'll delve more into fun generics reflection stuff later

this does the trick for now:

public static class Validator
{
    public static void Validate(this MonoBehaviour mb)
    {
        var fields = mb.GetType()
            .GetFields(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Static)
            .Where(f => f.GetCustomAttribute<RequiredReferenceAttribute>() != null)
            .Select(f => (f.Name, f.GetValue(mb) as UnityEngine.Object));
        foreach(var (Name, Value) in fields)
            if(Value == null)
                throw new MissingReferenceException($"Missing reference to {Name}");
    }
}

public class RequiredReferenceAttribute : Attribute
{ }

private void Awake()
{
    this.Validate();
}

👌

[tribal pivot]

private void Awake()
{
this.Validate();
}
Maybe you can make some editor script that, after you enter play mode, scans all components for this?

[cedar ledge]

an editor script that calls Validate() on each component in the scene?

what's the thing i need to search for to learn how to make a script that runs in edit mode AND runs without being in the scene?

[hollow garden]

or yano just cs public abstract class InsertName : MonoBehaviour { protected virtual void Awake() { this.Validate(); } } and then ```cs
public class Script : InsertName {

}

altho that feels weird

[cedar ledge]

yeah but i dont want everything to inherit like that lol

it gets more and more wonky the more weird features like that you want

[plucky laurel]

if you are mixing runtime here, you will get runtime overhead from the components that are interested themselves

if you are doing clean editor time, you will have to scan every prefab, every component in the project, which is slow, but its not runtime

[tribal pivot]

https://docs.unity3d.com/ScriptReference/InitializeOnLoadAttribute.html
https://docs.unity3d.com/ScriptReference/EditorApplication-playModeStateChanged.html

The latter one has a complete example

[tribal pivot]

Or, if it works for you, only search in the current scene. Maybe thats fine as well

[plucky laurel]

detecting project change works in many cases, but im not sure how to deal with edits to components then

[cedar ledge]

that caused some funkiness

the yellow bits are leftover playmode tint lol

they arent going away

k that worked perfectly

feel free to add performance improvements but im gonna leave it at that for now

[tribal pivot]

Id personally not throw a missing ref exception. Its saying "Missing reference to abc, good luck finding it lol!"
I'd do a LogError, pass in the object that broke it in the context parameter. That way you know exactly what is missing, and where

[cedar ledge]

fair enough. i guess once you move the error away from the class its a pretty good idea to use that debug.logerror functionality to direct the programmer to the right place

[hollow garden]

could probably use TypeCache instead of reflection there

[cedar ledge]

im not familliar

[hollow garden]

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

[cedar ledge]

public static void Validate(this MonoBehaviour mb)
{
    var fields = TypeCache.GetFieldsWithAttribute(typeof(RequiredReferenceAttribute))
        .Select(f => (f.Name, f.GetValue(mb) as UnityEngine.Object));
    foreach(var (Name, Value) in fields)
        if(Value == null) Debug.LogError($"Missing reference to {Name}", mb);
}

works the same, nice

[hollow garden]

nice

[cedar ledge]

kinda cool that unity provides a way to get all fields from all cached types with the attribute just like that

[hollow garden]

yeah it's really useful in editor code

[plucky laurel]

oh yeah TypeCache never used, that one bypasses the gc issue, but for editor only sadly

[flint sage]

Wouldn't that also fail if you have a non UnityEngine.Object typed field with that attribute?

Which should be ignored rather than throw an error

[cedar ledge]

is Unity.Object the only thing that is a drag and drop reference in the editor?

[plucky laurel]

yeah afaik

[flint sage]

Yes

[cedar ledge]

so the attribute should have an error when put on something else

[plucky laurel]

you can copy paste other things, like SerializeReference refs, or anything with Odin

i dont know if it works in base unity, try right clicking some property in editor

[cedar ledge]

how do i filter so that i only select where the field is from a monobehavior

[plucky laurel]

declaring type afaik

[fresh salmon]

With something like that yeah

[cedar ledge]

there it is

[fresh salmon]

x.DeclaringType.IsAssignableTo(typeof(MonoBehaviour))?

[plucky laurel]

if(declaring.IsSubclassOf(typeof(MonoBehaviour)))

[cedar ledge]

i had .Where(f => f.DeclaringType == mb.GetType()) but it didnt filter it

[plucky laurel]

this is not how you use it

var fields = TypeCache.GetFieldsWithAttribute(typeof(RequiredReferenceAttribute))

this probably returns you all fields in the whole assembly

what does it return btw?

[cedar ledge]

yeah i only need the fields of the class im currently looping over

fieldinfocollection

[plucky laurel]

and whats an element of it?

i assume its some unity type

[cedar ledge]

FieldInfo

from Reflection

[plucky laurel]

weird

you should probably prefilter them by type, or do it somehow else

with current approach you are iterating all fields in the project and testing each, every time

[cedar ledge]

IsAssignableFrom?

[fresh salmon]

I don't remember which one to use here, but the logic said "can the declaring type be assigned to a variable of type MB?" in my head

[plucky laurel]

yes its IsAssignableFrom

[fresh salmon]

And it seemed alright to me

Both exist

[cedar ledge]

i didnt see To

[fresh salmon]

Ah, To is .NET5 and above

That's why

[plucky laurel]

so on the left should be the type you want to cast to, and on the right what you want to cast

[cedar ledge]

should i just change it back to not using TypeCache? seems wasteful to loop over all fields of everything for each gameobject in the scene

[plucky laurel]

is that the only api you can use in it?

[cedar ledge]

which api

this bugger pops up in every project i make in any version of unity

😠

[plucky laurel]

never goes away

[cedar ledge]

so it's not just me

[plucky laurel]

its gonna be year 2077 and its still be there, my guess

[cedar ledge]

.Where(f => f.FieldType.IsSubclassOf(typeof(UnityEngine.Object)))

i put it back to reflections and added that

it doesnt throw an error for my vector3 so it works

[plucky laurel]

This method also returns false if c and the current Type are equal.

keep in mind

[cedar ledge]

ugh

is there a better method or do i just add an or condition

[plucky laurel]

i think the only "pure" UnityEngine.Object is a "folder"

[cedar ledge]

thats wack

[plucky laurel]

youre probably safe

[cedar ledge]

i got it

just had to swap the object to the left

k i've officially overengineered my class-final-project-in-24-hours game

[cedar ledge]

doing a similar thing for AutoComponent

foreach(var f in fields)
{
    f.SetValue(mb, mb.GetComponent<>());
}

what should I put in the <> ?

[tribal pivot]

The type you want to get. But with generics, you need to know beforehand. You could use the non-generic variant if you dont

[cedar ledge]

f.SetValue(mb, mb.GetComponent<f.FieldType>());
complains that f is a variable but being used like a type

wait

i didn't even know there was a non generic version

f.SetValue(mb, mb.GetComponent(f.FieldType)); works

[tribal pivot]

Generics in C# have to be known by the compiler beforehand. Its not dynamic.

f.DeclaringType is a variable, the compiler cant know this beforehand.

[cedar ledge]

yeah i just wanted to know how to work around it and that worked perfectly

I'm doing f.SetValue(mb, mb.GetComponent(f.FieldType)); and it successfully finds the component but then it still has an NRE when i use it in Start() of the script

i think that the start is running first let me investigate that

does start run before playModeStateChanged?

[austere jewel]

Start is called before, pretty sure

[cedar ledge]

because im getting the debug log after the NRE from start

the debug log is called from playmodestatechange

NRE is from start

[tribal pivot]

And you're doing all this just so you dont have to drag it in?

[cedar ledge]

it's academic

[tribal pivot]

Yeah clearly

[cedar ledge]

PostProcessSceneAttribute

[granite viper]

Nah, those are DefaultAssets

[cedar ledge]

i changed the intialize on load functionality to post process scene and everything works

if you ever wanted [AutoComponent] for automatically assigning your component references and [RequiredReference] for validating serialized fields when the scene plays (prevent forgetting to set them) here you go

i hope this isnt against the rules, i just dont want to flood the channel with even more of the same code

[tribal pivot]

Awesome, thanks for sharing!

[cedar ledge]

here's the usage just for quick reference

[wicked pine]

if i am currently drawing sprites in code in a horizontal line (in a for loop) for my player health (hearts / empty and full). I want to draw these along a bezier line. Is there a easy way to align sprites along a line in a UI? should I just forgo the drawing horizontally and just take a XY for each sprite? and manually draw them? Its for a UI and it goes along a curved background so I was thinking of either somehow drawing a line and aligning them all along the line? I do own ALINE 3rd party tool just in case that has any relevance, TLDR can i draw sprites along a curved line or should I make 10 points for 10 hearts and just manually asign them to the list of 10 points

Hey all, I've got a quick design question I've been going back and forth on in my head:
What is the best way to write maintainable C# MonoBehaviours?

It seems to me that we have the choice to either create larger, highly cohesive classes (Player) that become a massive burden to change and maintain due to size and complexity OR we create smaller classes (PlayerMovement, PlayerAttacking, PlayerInventory, PlayerHealth, etc) and split the functionality out making the classes easier to maintain but increasing the likelihood of bugs due to all the additional references that need to be wired up (either with requirecomponent or drag+drop in editor)

Any thoughts?

[tribal pivot]

Unity mostly works with components, and imo that works well.

I do avoid RequireComponent for the runtime overhead.
If you destroy a component it will search if there is no RequireComponent on it.

[proven hatch]

How do you handle the complexity of wiring up references?

seems like we open up all sorts of avenues for bugs

[tribal pivot]

Well arent you in luck 🙂

How i do it is to have one central PlayerController, everyone links to that. And in turn, PlayerController also serializes a reference to the other components.

You could also only link from one to the other, making the dependencies very clear

[proven hatch]

Supposing we go with a components approach, how do you determine whether a thing is a component or a game object?

[tribal pivot]

That guy above just made some RequireComponent, and AutoComponent.

We have something similar called GetComponent, which automatically grabs a reference when you open the inspector.

[tribal pivot]

What do you mean? A GameObject is something completely different in Unity

[proven hatch]

"Projectile" for example

Is this a component or a game object? (prefab, for example)

[tribal pivot]

Im sorry but the difference between a gameobject and a component is very big

A GameObject is a collection of components. Its a tag, a name, a bunch of components.

A projectile is a gameobject, with the components ProjectileMovement, ProjectileCollision, ParticleSystem.

[proven hatch]

Is "Head" not a "component" of a "Body"?

[tribal pivot]

No, it is a GameObject within a body, with a Transform component.

[proven hatch]

so you do not compose a Head with a Neck and so on to form your body?

[wicked pine]

and your brain is a gameObject nested inside your head 😄

[tribal pivot]

Yes, this is a transform hierarchy. Those are different gameobjects.

[wicked pine]

filled with all sorts of inactive unused deprecated components 😦

[proven hatch]

...if it is composed then it is a component of the whole

you see what I'm getting at?

how do you know whether something should be a MonoBehaviour (component) or a GameObject (component)

[tribal pivot]

No, i think you're asking what the difference between a component and a gameobject is in code-advanced.

[tribal pivot]

GameObject is not a (component). You cant inherit from GameObject.

[proven hatch]

You're giving me an answer in terms of code, I'm asking for an answer in terms of design

obviously I wouldn't need to ask in discord for the answer in terms of code, the documentation is available

[wicked pine]

if you goto a store and ask the guy to help you pick out windows and then realize you were calling a door a window, you realize that terms matter

[tribal pivot]

A head is a GameObject, with a bunch of components. Since it has a position it has a Transform component.

[cedar ledge]

is there a way to fix the fact that visual studio thinks that a private serialized field is never assigned to, and suggests it should be readonly?

i dont think that somehow adding the relevant suppressmessage attribute to everything with the serializefield attribute in an editor script is the "right way"

mostly i dont want to clog up my code with a million pragma warning disables, and i do find that suggestion helpful sometimes

this was my first idea (AddAttribute is not a thing)

public static class SerializedSuppresor
{
    public static void Suppress(this MonoBehaviour mb)
    {
        var fields = mb.GetType()
            .GetFields(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Static)
            .Where(f => f.GetCustomAttribute<SerializeField>() != null);
        foreach(var field in fields)
            field.AddAttribute(new System.Diagnostics.CodeAnalysis.SuppressMessageAttribute("IDE0044", "IDE0044"));
    }
    [InitializeOnLoadMethod]
    private static void SuppressEverything()
    {
        foreach(var mb in UnityEngine.Object.FindObjectsOfType<MonoBehaviour>())
            mb.Suppress();
    }
}

[tribal pivot]

Configure your ide to ignore the warnings?

[cedar ledge]

how do i configure it to only ignore it when the field has the serializefield attribute?

[tribal pivot]

I dont think thats possible out of the box

[cedar ledge]

darn

[final steeple]

There are already analyzers that achieve this

They should be built-in if you install the Unity tools for VS

[cedar ledge]

i have it installed

hmmm

[final steeple]

There is also https://github.com/microsoft/Microsoft.Unity.Analyzers

[final steeple]

https://github.com/microsoft/Microsoft.Unity.Analyzers/blob/main/src/Microsoft.Unity.Analyzers/SerializeFieldSuppressor.cs

[cedar ledge]

is the best way to install this using the way you were showing me a while ago, or do i just do it from vs2022

[final steeple]

The easiest way would be to just install the VS extension yeah

You could embed the analyzers in the project but it's significantly more work

[cedar ledge]

it says that the analyzer should be included already

i did the vs code installation anyway and no dice

I'm trying to use Rigidbody.AddExplosionForce(...) for rocket launchers in my game, and each player is a capsule collider. One problem that I've noticed, however, is that if the explosion is on the player but below its center, the player, they aren't launched into the air, but just pushed backwards.

Which makes sense if you think about it

But that's not the style that I'm going for

Is there a way to add explosion force based on the center of the player?

[cedar ledge]

https://docs.unity3d.com/ScriptReference/Rigidbody-centerOfMass.html
will this work for you?

for each hit, apply the force in the direction of (centerOfMass - explosionOrigin)

Hello, I have a script Player that has an array of Tile gameObjects in specific positions.

As seen here, the blue board is the player and the gameObjects are those visible tiles.

I want to create a backup of those tiles which would basically be a duplicate array of the player's hand, by using deep cloning.

I wanted to ask if that's the appropriate action to take for an option to "Undo" the player's move if I can do something else.

[quartz stratus]

If you go the cloning route, I would recommend making the duplicate backup arrays be not of type Tile. If you expect to generate a lot of these duplicates. I would investigate creating some kind of ID system so your arrays can be of a different type

[olive lion]

I'm not sure I follow, what kind of an ID system?
I wanted at first to create an array of references themselves to the gameObjects so I can use them later on but I can't seem to think of a proper idea.

[timber flame]

There are some chunks and each contains voxels.
Is it standard to use IJob for each chunk and inside, utilize IJobParallelFor to calculate some math/calculation for each voxel?
Then after all chunks are ready (JobHandle.CompleteAll), render meshes.

[foggy canyon]

specialAttackCoolDownTimer -= Time.deltaTime; seems to be taking double the amount of time I think it should. I'm setting it to 6f but its taking 12 seconds to get to 0 in my update function

[long ivy]

what is Time.timeScale set to?

[foggy canyon]

it's set to default, but it's ok I figured it out after some more digging.

[brittle pumice]

@plucky laurel so if I programmatically copy a static class/ file into my project I want to immediately execute one of the functions

There has to be some sorry Of attribute in unity that allows me to do this

I found [unityEditor.callback.didReloadScrip]

But that only trigger on second import

[jovial totem]

ok so. I need to make an A* Algorithm. But my node graph is a bit nonstandard, so I can't conceptualize it in my head.
My nodes have a position that they are in, and also a world, which is a completely separate space, and nodes can connect between worlds (like portals). However, the worlds' physical space do not line up; a node at (2,2) in world "Overworld" may connect to (0,0) in world "Dungeon". so how on earth do I do Heuristics for A*?

or do I need to do a separate pathfinding algorithm entirelty

[dense tusk]

Are you wanting an entity to be able to path through multiple worlds?

[jovial totem]

Yes

[dense tusk]

In that case I'd take a theoretical view at how A* works. As you probably know, all it does is assign each spot on a grid a value depending on the destination (and other modifiers a dev might put in IE maybe a tile is a "quicksand" tile or something that might increase it's movement cost in A star), and then uses those values to find the fastest path to the destination.

While this is great for a single map, it gets far more complicated when stitching bits and pieces together (although it's of course doable).

Perhaps in this instance, you could simply use standard A star to path to the appropriate "portal" node and then repath after it enters a new "world"

though you might want to keep a pool of data for each world that includes where each portal leads etc. So you could theoretically have an entity path from World A to world Y by stringing together various paths to portals based on qualifying factors

[jovial totem]

Yeah I’m slowly coming to the conclusion that I’m going to have to do separate path finding for each world

Well. Since each world is a physical space, whenever the algorithm enters a portal it could adjust the coordinates of the new world to match like putting a pin through paper

This does not need to have unit accuracy

[regal olive]

I'd love it if someone could perhaps help me with Animation Events? I'm trying to figure out how to use the Object reference parameter with some custom object types (in my case, hitbox parameters, for instance). How do I use AnimationEvent objects, the docs are about as clear as muddy water lol

Some code for ref.

[humble onyx]

you may be able to reference a ScriptableObject that holds the data you need.

[undone coral]

have you looked at ultimate fighting toolkit?

is this your code?

[undone coral]

is this rummikub?

[undone coral]

in my experience it is easy to write maintainable monobehaviors for things that already look like CRUD applications - an inventory system, menus, dialogue trees, etc.. Everything else follows really specific traditions that you should follow. like don't make a "maintainable" "FPS" "controller," find a historic implementation and reuse it

[regal olive]

Yes, this is my code. I've implemented a "custom scripting" system using Scriptable Objects, and I want to translate them to Animation events created via code (clip.AddEvent(x). I'm using the AE's for timing purposes, as I can't seem to recreate perfect frame timing with my custom system alone.

[worldly gorge]

I posted this in code-beginner, I don't think this question belongs in there.

Using a compute shader, I call GetData() immediately after Dispatch(), is this good design? Or should I be calling Dispatch() as soon as possible and GetData() as late as possible similar to Unity's Job system?

[olive lion]

Yes!

[unkempt nova]

So I'm making a spell that needs to make ice spikes in a radius around a target position. I'm using a Vogel spiral to pack them. GetSpiralPositions returns a list of positions corresponding to the positions in a spiral. I'm trying to "normalize" these positions, so that they all fit within a given radius by simply finding the magnitude of these positions, and then multiplying them all by a constant value calculated by the ratio of the radius to the maximum of these magnitudes.

Method:

public List<Vector2> GetSpiralPositions(int positions, float radius) {
        float theta = 0;
        float maxLength = 0;
        var returnValue = new List<Vector2>();

        // Algorithm adapted from http://www.smokycogs.com/blog/drawing-spirals-in-c-sharp/
        while (theta <= positions * 360) {
            theta += 137.5f;
            var currentRadius = Mathf.Sqrt(theta);
            var currentPosition = new Vector2(Mathf.Cos(theta / 180 * Mathf.PI), Mathf.Sin(theta / 180 * Mathf.PI)) * currentRadius;
            float length = currentPosition.magnitude;
            if (length > maxLength) {
                maxLength = length;
            }
            returnValue.Add(currentPosition);
        }
        Debug.LogFormat("MaxLength: {0}", maxLength);
        
        // Go through each return value and "renormalize" the values, so they fit in the radius.
        float normalizedMaxLength = 0;
        for (int i = 0; i < returnValue.Count; i++) {
            returnValue[i] *= radius / maxLength;
            float length = returnValue[i].magnitude;
            if (length > normalizedMaxLength) {
                normalizedMaxLength = length;
            }
        }
        Debug.LogFormat("NormalizedMaxLength: {0}", normalizedMaxLength);
        return returnValue;
    }

Full script: https://www.toptal.com/developers/hastebin/ulasegupuy.csharp
I am testing this by spawning a sphere with the same radius at the same position. I expect that all of the positions given by GetSpiralPositions to be inside of this larger sphere, but I'm getting them outside of it. Not sure why, any ideas? I'm calculating the max renormalized length and logging it, it's 5
Here's a pic of what I'm seeing, small spheres are in positions yielded by GetSpiralPositions

Pattern is correct though, just something weird with my "renormalization"

Also, I'm aware I have a currentRadius already and don't need to calculate length again, just wanted to be double sure. Trying to just use it yields the same result

[glacial wedge]

to reduce compile time each time I save one script in a big project I have to create .asmdef file or something to make unity compile only scripts in the folder where the script changes?

ok, found it! https://learn.unity.com/tutorial/working-with-assembly-definitions#

[unkempt nova]

Infallible Code did a video on them too, but they're still black magic to me

[glacial wedge]

I'm struggling with the options

what it means?

Which are the "predefined Assemblies"? It's the default "AssemblyCSharp" or what else?

[thick birch]

Is there a way to make a list into a property that checks if the element we are trying to get even exists or is within the array length?

The list is with a custom class also, if that matters cs private List<SlideDigit> digitsList = new(6);

[scenic marlin]

so im working on voxel game and i have no idea what to do now because this is nuts my max object size i was planing in bytes is large
(16 777 216 voxels) * (8 bytes) with gives me 128 MB per object
with is not good for streaming it in anyway (network,gpu,hard drive) and files will be large yes i can split it but problem stays the same
so i was thinking about using a bits instead of bytes

min bits i can store is 8 per byte
so lets say
"[0]0000000"
fist bit is a voxel state 0 full 1 empty with leave me with 7 bits to use
so i need to fit color data
with dynamic color is out i need to use palette any idea how to encode it

final size for object i can get is 16 mb

[novel plinth]

tupple can be useful for such situation

    public (bool exist, SomeObj item) GetSetItem(objParam item)
    {
        (bool exist, SomeObj item) ditem = (false, null);
        ditem.item = someList.Find(x => x == item);

        if(ditem.item != null)
            ditem.exist = true;

        return ditem;
    }

[thick birch]

that looks overcomplicated

[novel plinth]

do you think? 😃

[thick birch]

what im doing is split the datetime time into separate digits and for each element of that class and do cs digitsList[0].SlideVertical(targetDigit, transitionTime);

i know of another way that involves formatting it into a string and just doing a for loop, but it feels like that one would have too much GC

[final steeple]

Yes. If Auto Referenced is enabled, then your assembly definition is automatically referenced by Assembly-CSharp and Assembly-CSharp-Editor

[sick robin]

    {
        if (!photonView.isMine)

            }

            this.GetComponent<PhotonView>().RPC("DestroyObject", PhotonTargets.AllBuffered);
        }
    } ```

Hello, i am trying to instantiate the bloodsplat particles when the player gets hit, however it only appears on the client side, it doesnt show up on the other clients side.

how can i make it so it appears on both sides

[livid kraken]

PhotonNetwork has a Instantiate implementation that will spawn object over the nerwork

Otherwise you got to call a rpc or raise your own netwotk event

[brazen dragon]

I've been working on an inventory system and I made my items scriptable objects. I then made a item database that has a list of items that I populated with my item assets. Then, when I want a certain item I'm doing an instantiate inside the item database on one of these items to get a copy.

I don't know if this is a good way to do it. Does it sound OK?

[sly grove]

Sounds fine

[thick birch]

Whats the problem for it assigning the previous duplicate element instead of the next one?

private void OnValidate()
    {
        SlideDigit[] allSlideDigit;

        allSlideDigit = GetComponentsInChildren<SlideDigit>();

        for (int i = 0; i < allSlideDigit.Length; i++)
        {
            if (!digitsList.Contains(allSlideDigit[i]))//if we dont have a class in the list
            {
                for (int j = 0; j < digitsList.Count; j++)
                {
                    if (digitsList[j] == null)//assing it to the free element
                    {
                        digitsList[j] = allSlideDigit[i];
                        break;
                    }
                }
            }
        }
    }

[wooden cedar]

You really need to stop nesting like that and start using foreach

I don't really understand your question or what you are trying to do

[thick birch]

its just 2 for's- and im trying to automatically assign any missing components if theres a free slot

[wooden cedar]

It's two for and two if statements that seem to be rather redundant and uneeded

[thick birch]

foreach is also slower, plus its doing literally the sam ething in the end; i just went the for route

[thick birch]

how is it unneeded?

it goes through the GetComponentsInChildren list, if one of the components it goes through isnt in the actual class's list, go through the class's list and if it finds an empty (null) element, assign it there

[wooden cedar]

The only thing you care about is if digitList[index] is null, so a huge chunk of your time spent in the for and if statements looping through elements is wasting time.

[thick birch]

🤔

[wooden cedar]

You say it's faster, I say it's backwards. As 95% of the time it'll ignore the element at the last if null statement

Anyway you seem intent to do it the way you are so I won't nitpick and let you work through it how your comfortable

[thick birch]

i was just wondering why its not assigning the right element if its just one added element instead of the whole list

(like in the video)

[wooden cedar]

    
private void OnValidate()
{
    // only gather null list item entries
    foreach (var listItem in digitsList.Where(x=>x==null) {

        // find missing children
        var firstMissingItem = allSlideDigit.FirstOrDefault(x=>!digitsList.Contains(x));

        // assign it if we found one
        if (firstMissingItem!=null)
            listItem = firstMissingItem;

    }
}

That's how I would tackle that. I havent tested the code, and you can separate it from LinQ if you want.

[wooden cedar]

Or if you want simplier, non-linQ

private void OnValidate()
{
    var allSlideDigit = GetComponentsInChildren<SlideDigit>();
    for (int j = 0; j < digitsList.Count; j++)
    {
        if (digitsList[j] == null && j < allSlideDigit.Count)
            digitsList[j] = allSlideDigit[j];
    }
}

[thick birch]

@wooden cedar these dont work as my code though; its assigning it differently

theres a reason why i have two for loops

theres an array, and a list

they are different

[wooden cedar]

I know

[thick birch]

the list can have less elements than the array

[wooden cedar]

I know

[thick birch]

🤔

let me try the non-linq one

[wooden cedar]

You are going through a list, looking for empties, and assigning the first item missing from an array of children

[thick birch]

yup

wait no

looking through an array, checking if the element in the array is in the list , and if its not , assign it

[wooden cedar]

Well what you are actually doing is going through a list of children, checking if they are missing from the list, then checking if the list has any empties, and then assigning it to the list.

Which is backwards. Because if the list, which changes rarely, has no empties - the rest doesnt matter.

Hense, why I inverted it

[thick birch]

gotcha

[wooden cedar]

As it is, you are marching through all the children regardless of if the list even has an empty

[thick birch]

well your non-linq code has the same problem

unless i go from 0 elements to the chosen amount, it will just keep duplicating the last one

[wooden cedar]

I cant, eye ball wise, see why your original code was doing that either, i kind of hoped it was just a j vs i for loop issue. Sorry my friend

[thick birch]

weird

Can you elaborate on "doesn't work"?

Are you getting errors?

Is the wrong thing writing to the file?

Is the wrong thing reading from the file?

Provide some details

hey, I have a snippet that works until my character is rotated:

            {
                Vector3 worldPoint = ray.GetPoint( distance );
                direction = ( (worldPoint - GunTip.position)  ).normalized;
                Direction = direction;
            }```

my character travels on Z

Im trying to shoot towards my mouse

[orchid hinge]

umm sorry for the wait I dont get any errors however I do get weird behavor that should not happen(behaves very differently than what I saved)

[undone coral]

sick. i think the best thing to do is, the UI "stages" the player's move, and then once they end their turn, it's committed. that seems clunkier though - how often will people undo?

[undone coral]

yeah it's very very tricky. i mention the other asset because it aspires to do the frame timing and maybe it's worth buying to study it. i own it but haven't researched it yet

[olive lion]

It changes the tiles on the board, and then when clicking the Finish Turn button it checks the board's validity, if not valid then it returns all the tiles back to the player's hand.

In case you wonder how it looks here:

[proven hatch]

"traditions" seems like an extreme anti-pattern.. no way to utilize knowledge of software engineering, just gotta memorize the gotchas

[dire berry]

Guys, would u rather use PlayerPrefs or create a custom static class that stores your data? And why?

[novel wing]

PlayerPrefs = simple preferences. Stuff like volume, player nickname, shadow quality etc. For actual save data you use a custom saving system

[dire berry]

Ok thankyou!

[sly grove]

Neither

Make a properly structured data class and serialize it

[dire berry]

Thank you very much

[wraith wedge]

hello so i have a problem with my game at the moment

so when i create a room it creates it but it doesnt show a join room button

it was working but then i added some unity assets and it doesnt work anymore

[regal olive]

Indeed. This is a fangame so I'd rather not have to invest in money assets, etc. I just can't seem to recreate this perfect timing events have. The game's framerate always gets in the way with its spontaneous changes.

[rocky mica]

yeah Unity sucks for fighting games

timing is extremely tricky

and if you want to implement rollback netcode you gotta reimplement half of unity stuff due to lack of determinism

[regal olive]

It's a shame, because Unity is so damn easy to use (for the most part). So really for this I have NO choice but to use the events. I didn't want to, but custom timing stuff is virtually impossible to implement.

[rocky mica]

yup yup

Best bet would to get UFE

it's a bit of a pita to use but at least it works

[quartz stratus]

You've given us almost no specific information here, really impossible to help. Also possibly sounds like a #💻┃code-beginner question.

[regal olive]

i don't know if this is the most appropriate place to post this but i can't find anything on google and it's making me go crazy, every time i scroll the inspector it has those trail things, at first i thought it was my monitor, but then i confirmed it happens on my other monitors too, secondly i tried to record it and sure enough that's what is being processed, if anyone has any solution please help me, i feel like jumping the boat and freaking out about my graphics card won't help, but i did notice something similar happening in KSP

it started today, i didn't update drivers or anything

[rocky mica]

UH

that looks like graphic card artifacting yeah

[sage radish]

What graphics card do you have? Have you updated drivers for it recently?

[regal olive]

i have an RTX 3070, and no didn't update any drivers

[sage radish]

I would try that then

[rocky mica]

praying for that card

[regal olive]

yeah it served me well, got it for cheap at the height of the chip shortage too

[regal olive]

i will see if there are any updates

i also noticed that they only disappear when i move the mouse

could it be a unity screen refresh issue?

yeah updating the drivers didn't help

ok

thank God

i reset all my nvidia control panel settings and it seems to have fixed it

sorry for bothering you guys, i was just really worried about my gpu

[regal olive]

I'd rather not, if possible, but animation events should still do the trick. We'll see, I have an idea on how to implement my system via the events.

[rocky mica]

If you arent blending

then animation events would work

if you are blending then they wont, blended animations still send events

you would run into weird cases where cancelling some animation states would still send events

the value of an FPS is people's familiarity with it. modern warfare and fortnite, the last two FPSes with a large portion of the audience new to the genre, are based on decade + old engines. best not to innovate in the least interesting part of an FPS, the controls and weapon behaviors. behold, with the exception of maybe Portal long ago, there hasn't been a new idea in a weapon / FPS movement since

[proven hatch]

Apologies, I thought you were referring to traditions of MonoBehaviour design not game mechanic design

[undone coral]

sort of. if i were authoring an FPS, i would copy the code of a pre-existing FPS exactly, to start

unity is bad for FPSes, but i hear good things about Opsive's asset

if you were going to make an FPS, use unreal

like what is there to maintain? better to not maintain that stuff at all

[proven hatch]

I was referring to a more abstract concept than something that could be tied directly to a single genre

[undone coral]

there are gotchas in the biggest genres that should be memorized

lots of people try to make Metroidvanias with Unity for example

corgi 2.5d engine doesn't recreate it faithfully, but it's close enough

let moremountains maintain that stuff

[proven hatch]

Ahh I think I’ve encountered what you’re talking about. I’d call those “patterns” or “implementations”

[undone coral]

otherwise, it's a giant single class

because that's what metroidvania codebases looked like

and they did things that are only possible with god classes

[proven hatch]

Right.. kinda makes the whole “game dev” concept less creative and more ritualistic

[undone coral]

i agree. making a metroidvania is a ritual

and yet look at the success of Shovel Knight

[proven hatch]

At what price, though? Learning very specific details of very specific OOP or Unity quirks

Step into a new language or platform and I might as well be a junior again 😔

[undone coral]

the ceremony of cloning the basics of a game at least puts a working build in front of you

[proven hatch]

Also semi-time-gated upward mobility in the industry

(Great conversation btw, thanks for indulging me)

[frigid yoke]

question, does anybody know of a method to get mouse position even when the app is running in the background? (while tabbed out)

[sly grove]

Most operating systems won't allow this for security reasons

[frigid yoke]

found a solution

[orchid hinge]

This function is supposed to save my neural network and then later read the values from it and use them, idk why but it does not work https://gdl.space/ekayomivar.cs pls help. I dont get any errors however I do get weird behavor that should not happen(behaves very differently than what I saved)

Pls tag me

[granite viper]

@orchid hinge you should probably not be saving your floats as strings and parsing them

[orchid hinge]

Why not?

What's wrong about that?

[granite viper]

someone correct me if I'm wrong but I don't know if serializing floats that way is lossless

[orchid hinge]

So like I lose some of the information?

[granite viper]

potentially yeah

[orchid hinge]

Like from 0.287637 it saves 0.28764

[granite viper]

or something like that

[orchid hinge]

Oh

[granite viper]

better to save the actual bytes of the float

[orchid hinge]

That seems kinda complicated ngl

[orchid hinge]

Do u have a tutorial that u know that works?

[granite viper]

you're making a neural network

[orchid hinge]

Ye

[granite viper]

and you're saying that saving the bytes of a float is complicated

🤔

[orchid hinge]

Ye

Neural network is kinda easy when u don't do backpropagation

[granite viper]

@orchid hinge google ftw https://stackoverflow.com/questions/4635769/how-do-i-convert-an-array-of-floats-to-a-byte-and-back

[orchid hinge]

U just do prev neuron * weight (with each neuron) then u add a bias and sigmoid it

[granite viper]

cool beans

[orchid hinge]

The code doesnt even compile

[granite viper]

which code

[orchid hinge]

the answer

[flint sage]

You'll need system.buffers

[orchid hinge]

alr

[orchid hinge]

hmm that did not help lol

[flint sage]

In that one minute, you found the system.buffers dll, downloaded it, and copied it into Unity?

[orchid hinge]

?

[granite viper]

which answer

[orchid hinge]

Ill just use an yt tutorial

[granite viper]

ok

I guess that's easier than being specific

[orchid hinge]

@granite viper Technically I could multiply my floats by 1000 when saving and then when reading divide them by 1000

[granite viper]

sure, that might help

it's really not that difficult to just write the bytes tho

you can convert the 32 bit number into hex and then it'd be an exact (string) representation

[orchid hinge]

I save them as txt so I could instead of saving them immediatelly just pass them through a formater and then save them

[orchid hinge]

perfect this worked wonderfully

tysm for ur help

Its like a dumbass sollution but that kinda suits me lol

[granite viper]

glad you figured out a fix

hey whatever works

[orchid hinge]

ye tysm again

[foggy dew]

do you have any ideas how to rotate overlapbox depends on player x movement

smth like this

    {
        var move = movement.Move;

        if(move == Vector3.zero) return null;

        return Physics.OverlapBox(transform.position + boxPos, boxSize, Quaternion.LookRotation(move.normalized, Vector3.up), interactableLayer);
    }```

I've tried this but its not working quite well, it works but like its happening with delay

[chrome vault]

im keeping getting this error

i dont know how can i fix that

[devout hare]

edit: not advanced question, keep it in code-beginner

[humble leaf]

@chrome vault Don't crosspost

[regal olive]

Is it possible to update value of random number after occurrence of one event

?

[plucky laurel]

show code, pseudo code, or anything that helps understand what you mean

[shadow seal]

Dw they crossposted

[regal olive]

https://media.discordapp.net/attachments/497874004401586176/967788809678880789/unknown.png

And there is if statement that checks if object reached target

[regal olive]

It this works then I need new float for z axis

[plucky laurel]

this is not an advanced question

[regal olive]

I am sorry

Can u please help

[regal olive]

New float is random number

@plucky laurel

[lime vine]

Hey, I'm not sure my question is advanced, but I'm seeking for knowledge about implementing AI that can fly through circles.
At the most basic version of it it's clear, but what if an agent is behind the circle and should get back to the track?

[twilit parrot]

I don't know if it is advanced but I needed to use RestSharp in my project due to API problems and the function that executes the request freezes the main thread even with coroutines. What would you suggest for this situation? Should I use another thread as the value is not required immediately?

[random goblet]

How I get this string in another script file?

[tribal pivot]

Thats not coding advanced. Thats code-beginner

[undone coral]

you can use UniTask to run restsharp's async methods on a worker thread while setting data on the unity thread within one Task

that said you probably do not need to use restsharp. are you trying to use an openapi generated client?

[twilit parrot]

yes

[undone coral]

so it's not really an api problem

use unitask and the async version of the generated client

[twilit parrot]

my problem wasn't the restsharp but the how I handled the response. Basically. I wrote wav file into disk with File.WriteAllBytes and it obviously creates a thread and makes the whole Unity wait.

[undone coral]

the blocking call is going to do just that... block

you can use the async write calls

[twilit parrot]

not my brightest day tbh

[undone coral]

you shouldn't be creating threads

use unitask / async await to do this stuff expressively

[twilit parrot]

Thank you. I will correct it.

[undone coral]

you're doing great

you're using openapi... you're already miles above everyone else here

[rocky mica]

uh no?

having the same script doesnt mean they have the same exact state

it's as simple as having a boolean to check if it was fired or not

[tribal pivot]

Which of the two should be destroyed?

[rocky mica]

then yeah, just have a boolean check if it was fired or not

it's trivial

[tribal pivot]

For you, but not for everyone.

[rocky mica]

"i want the one that was fired to destroy"

[tribal pivot]

You'll need to be able to differentiate this. What does it mean to be already on the floor?

Is it the one with the lowest Y, or the one with a bool isOnTheFloor?

[rocky mica]

you have some kind of other script thats firing this prefab

[tribal pivot]

Please try to include as much information as possible

[random goblet]

It's because it takes the data from database, it's a multiplayer game, and I wanted to know how I get the token of the user who is logged in...

[rocky mica]

I am afraid you will need to be more specific about your issue

is the prefab already a poison pool when its travelling? does it become one in contact? how does that work

you need to be more specific, we dont read minds

then again, just have a bool to differentiate them

your boss spawns those prefabs

you can use the boolean or a string or whatever variable you want to store its current state

the way I see it, if your prefab is travelling it has one state, and if its not it has another

your boss should set that on instantiation

and the projectile should change that when becoming stationary

well, now you know what to do 😄

[wanton pagoda]

let me think it through a bit

im just tired

of sitting coding 11h straight

xD

private void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.name == "PoisonPool")
        {
            //destroy other
        }

this should work right?

even if's the same "object" its not the same instance

[rocky mica]

that will destroy both most likely lol

or one of them, randomly

again, you need a way to differentiate them

[wanton pagoda]

no!

its working!

: D

i was just overthinking it

like an idiot

[rocky mica]

unless you are using the name for differentiating

which is...

uh...

questionable

[wanton pagoda]

im not

its destroying other

        if (other.gameObject.name == "PoisonPool")
        {
            Destroy(other.gameObject);
        }

[rocky mica]

good for you, next time ask away in #archived-code-general and provide more details 😄

[wanton pagoda]

but i can see why we both think it should destroy both tho

im a bit confused

what's going on xD

[flat rain]

so i have a monitor model
how can i make an "OS" in it
and be able to display it

[devout hare]

Don't cross-post, stay in code-general

[random goblet]

How I set texture from path when player click on button?
I tried this, but don't work:

Material FloorPaint = Resources.Load("/Prefabs/GameData/Paints/Floor/Wood/Texture", typeof(Material)) as Material;

[fresh salmon]

Using Resources.Load requires your item to be in a valid resource folder. Means you need to have a folder named "Resources" that path is in. For you, anywhere under your Assets, it'll search for a Resources/Prefabs/GameData/Paints/Floor/Wood/ folder

[shadow seal]

The docs do tell you

And I should hope that at this level, we are reviewing the docs

[rocky mica]

Gimme a minute, i did this last year

you can load pngs as valid textures from any folder in windows

lol

[fresh salmon]

What?

[rocky mica]

but yeah, if you wanna use real Resources

you should use the resource folder

[rocky mica]

what what lol

you can do it haha

[shadow seal]

We're loading a Unity Texture not a PNG
