reactive property and subject are both IObserver i.e. they define OnNext

if you want to be pedantic you can protect your health from outside stuff mucking with it using IReadOnlyReactiveProperty

that way only the private things can OnNext onto it

the deathrattle example i'm showing you so that you can implement things like the character falling over and dying

[obtuse flume]

So when accessing ReactiveProperty does it store all of the past values too?

[undone coral]

no

but there are things that do that

in unirx

behaviorsubject is one of them

and can be used for weird stuff, or to deal with "Bugs" like "do i have to worry about what order this stuff happens in"

for example, a thing might have already died before you started listening for it to die

very tricky

[obtuse flume]

What does killedBy: source, amount: amount do?

[undone coral]

whoops i fixed it

that was just naming the parameters

this way you could have it wait until it plays its tombstone and death animation

before spawning some critters

which is Good Game Feel

so you would have a bunch of IDeathrattle components and they would execute in order

maybe you want to NOT wait for some of them. use a bool dontAwait

and check it. if it's true, Async().Forget() instead of await Async

[obtuse flume]

Ok so you are just playing a death animation before you destroy, and this way you don't have to have some convoluted way to track when every single deathrattle has finished their animations?

[undone coral]

yes

yes!!

You forgot your meds again

[undone coral]

lol

[undone coral]

ugh i've had bad luck helping people lately but this guy fucks is all i'm saying

it took only a few hours and there's already all this awesome stuff happening so i'm pretty happy

[obtuse flume]

this is exactly what i was looking for by posting here

[undone coral]

yeah, and the game looks nice

anyway i think this is really good ground covered and it is coming quickly

[obtuse flume]

we shouldve made a thread

[undone coral]

i like that Actor is like "my utility belt for all sorts of things i can do in the world" and you have different scripts that use those items on the utility belt

it's the right mix of coupled and decoupled that helps you solve problems expressively and without clutter

we have also so far avoided virtual which is great

there is a time and place for that

but you can solve like 99% of problems without virtual

[west scarab]

You can solve 99% of problems without anything fancy 😅

Everything is just a tool at the end

[undone coral]

yeah

i don't really mean to get too fancy

the point of all this really is to make your code look like an english language description of how the thing works.

[west scarab]

I'd argue reactive programming is already "fancy"

there's a lot of stuff going on

[undone coral]

we can stick to async

i agree reactive can be weird if you don't do the web development thing also

[misty glade]

I'd settle for 10 or 20% .. too many problems

[undone coral]

lol

[west scarab]

I don't think it's necessarily weird, it's just a style of programming that some people like and others don't

Maybe weird when first getting into it I guess?

[misty glade]

I saw an @ but wasn't around and lost the thread.. in and out for the evening - what was I supposed to comment on DrP? 🙂

[obtuse flume]

For sure, this is making my brain explode

[zenith ginkgo]

Death to UniRx

Sorry, my bad habits flaring up again

[undone coral]

lol

[west scarab]

I think the important thing if you haven't tried it is to see how you like the approach, not everything is for everyone, but you'll never know until you try it

[undone coral]

@obtuse flume well keep us posted on how things go and make sure to GIF & document some gameplay 🙂

[obtuse flume]

Yeah for sure. I wanted to improve my enemy behavior system because I am currently working on adding more interactive and interesting enemies than just "chase the player" or "move and shoot". You can see where my game was at 1.5 months ago at "Tony Dev" on YouTube. Not too much has changed yet.

[misty glade]

sync'd drum track overlaid on main track after the login button is clicked - I'm currently just playing these at the same time and turning the volume up to 100% on the second track - should I chain these to each other? and if so, thoughts on how?

(they aren't two separate tracks- they're a naked drum track and a background track)

It sounds fine "on my machine" but I worry that maybe there's a way these can get desync'd?

[undone coral]

looks really awesome

[rapid flume]

cool

[thorny lion]

is zenject popular?

[compact ingot]

It’s fun if a non-trivial message gets through. Makes it all worth it.

[compact ingot]

not in the grand scheme of things but it is among those who want to use a dependency injection framework in unity

[thorny lion]

I have watched a tutorial on yt and basically what it is for is to have singletons initialised before game has even started?

zenject seems to be super advanced tool that I am to early to put my hands on

just look at the import files. What is it all for? The documentation of zenject is longer than a thousand lines

what is the purpose of dependency injection in unity then?

unless FindObjectOfType<x>() does the stuff?

[compact ingot]

decoupling your systems by automatically injecting the references they need based on rules and contexts defined outside of them... in other words its used to separate dependencies from the concern of a particular implementation

there are many ways to do this, the simples one is to manually do it when instancing a class., the unity scene hierarchy and object references are also dependency injection and sort of a framework for that

a framework like zenject just adds a bunch more options and flexibility to it at the cost of more boilerplate code and potentially a very complex dependency resolution config that defeats all the benefits you gain from the decoupling

you need to figure out if your project and workflow and team organization benefits from using a dependency injection FRAMEWORK (hint: most game projects don't)

all code generally benefits from dependency injection (with or without a framework) that is done as part of implementing the inversion of control principle

[thorny lion]

my brain is going to hurt from all of that (omg)

anyways thank you

now I realise I do not need zenject because it is overloaded

[compact ingot]

yes, if you don't have a perceivable problem regarding coupling/decoupling and modularity of your code, you don't need it

[thorny lion]

hm you seem to be concerned a lot about it, can I ask you? My game has the only scene and a mono script called Themes.cs that handles themeing. I used to believe zenject would help me denote Themes.cs as a Singleton and easily refer to it in other scripts (instead of FindObjectOfType<Themes>().someField)

I know the rule of objects existence in which unique objects (just like Sun, Moon, the Earth) are not limited to be so and speaking so can become numerous

even you as a human can have a copy (purely identical instance) though the chance for it is 0.00000000000001%

such a rule dusts the concept of singletons in games, such as "there can be only one player at once". No. There can be many, but in our game it does not occur

respectively in my game I have a Themes.cs and I wish I could refer to its only instance from any script

Static? No. I need it to be a Mono

Singleton pattern? I hate it

FindObjectOfType<>()? Works perfectly but I hate doing it all the time

[modest vale]

What is the syntax for setting a variable to either <a> or <b> with faster if statement

[compact ingot]

i do not understand your question

[thorny lion]

do you know what a single mono per scene is?

like a god object but it handles events only within its scope

in the case of my Themes.cs there are only theme-related events and methods it performs

I don't need 2 of Themes.cs Monos in my scene or otherwise it will break the game

I want to assure my game I only have 1 mono and to have access to this mono without FindObjectOfType or inspector variable assigning

[shadow seal]

You can do that with a singleton

A singleton doesn't need FindObjectblah like you keep putting in

You have a static field which gives you a reference, the first instance fills in that reference, any other instances that appear should see that it's already filled and destroy themselves

[quaint swan]

how can i make that the wheels turn in the way the car is going

[lavish sail]

1. Use a variable instead of writing the same formulas 4 times
2. If car is going backwards, simply multiply that by -1

[quaint swan]

thats the point, how to know if the car is going backwards

[lavish sail]

get its local velocity and see if the front/back axis is positive or negative

[zenith ginkgo]

Assign Input.Axis * speed; to one variable. then assign that variable to all wheels

calculating it 4 times, is poor form

[quaint swan]

no seriously ?

just read the other messages plz

[quaint swan]

okay so the velocity is called MoveForce for me

but there is a problem

like for my speedometer the speed is always positive

so idk

[zenith ginkgo]

you have two ways to find out if you're going backwards or not

this. if its < 0, you're going backwards, or the cars velocity

[quaint swan]

i don't really understand

what would be < 0 ?

[zenith ginkgo]

the return value of your input

[thorny lion]

Ok do you know why some programmers say Singleton is an gamedev antipattern? I don't

[shadow seal]

I have no idea why, I don't use them often but I think a lot of it is down to people's opinions

[livid kraken]

Becauae someone with a milk box to stand on said it once

[quaint swan]

so its good if i write this like if(Inupt.....(Vertical) < 0):

[livid kraken]

Singletons are perfectly fine if used correctly

[quaint swan]

formula x -1

[quaint swan]

?

[thorny lion]

hm ok

[zenith ginkgo]

this is code advanced.

you should know what a return value is

[thorny lion]

What is ironical in a milk box though?

[quaint swan]

ahah yes.....

but what i wrote can work no ?

[zenith ginkgo]

what

[quaint swan]

so its good if i write this like if(Inupt.....(Vertical) < 0):

formula x -1

[zenith ginkgo]

theres more to it than that...

float movementDirection = Input.GetAxis("Vert");
bool isMovingForward = movementDirection > 0;
A.torque = movementDirection * speed;
B.torque = movementDirection * speed;
C.torque = movementDirection * speed;
D.torque = movementDirection * speed;```

thats all im going to give you

[shadow seal]

Just means somebody who thinks they know it all

[thorny lion]

hm fine that's a saying

[quaint swan]

kk

tyy

[zenith ginkgo]

for future questions like this, i'd advise using #💻┃code-beginner

[quaint swan]

ok thanks you man

[autumn topaz]

I changed the mesh of my rig and now its not working. its saying: System.InvalidOperationException: The TransformStreamHandle is invalid. Please use proper function to create the handle.

[obtuse flume]

Async stuff

[urban sequoia]

How did you change the mesh?

[autumn topaz]

I fixed it now, you just have to rebuild the rig but originally I just removed the model

[rugged radish]

I have a multipass compute shader which can run with a dynamic number of passes that is unknown on the CPU side in advance
current implementation has to readback the output after each pass and check if the task was completed on the CPU
are there any cheaper ways to accomplish this ?
currently I plan to add a 1-element buffer which tells the CPU that the task is done, but this still means requesting a readback after each pass and I doubt it'll save that much time

[modest vale]

aspectRatio.x = Mathf.Cos(dir) * vector.x - Mathf.Sin(dir) * vector.y;
aspectRatio.y = Mathf.Sin(dir) * vector.x + Mathf.Cos(dir) * vector.y;

what is wrong about this rotation matrix

[somber swift]

Nothing it seems, that doesnt work?

[modest vale]

yes indeed

it doesn t work for me

I hate rotation matrix

[somber swift]

Meaning?

[versed warren]

hacing trouble understanding what this error log means

Invalid allocation label passed to UnsafeUtility::Free
UnityEngine.StackTraceUtility:ExtractStackTrace ()

I'm using a networking script to look for servers on a local network

whenever I send data to the found server this error is logged

[somber swift]

@modest vale are you sure you are not confusing radians and degrees? Btw wdid you know that represents counter clockwise rotation, not clockwise. Otherwise that should work

[modest vale]

I think it works now, the problem is in the function that I wrote I *= instead of = the rotated position

[tame thistle]

When using the FromToRotate function, how do I preserve my other axis?

[sly grove]

Call FromToRotation on vectors that are only rotated on the axis you want to rotate on.

[tame thistle]

I am rotating the transform.up to the normal of a surface, are those not the only axis I am trying to rotate?

[sly grove]

You said "other axis" you'll have to explain precisely what you mean

[tame thistle]

Whenever I set my transform.up to the normal of another surface, the y axis is reset

i want to rotate the transform.up to the normal, without it turning my object to the same direction

should i word it better

[sly grove]

transform.rotation = Quaternion.LookRotation(Vector3.projectOnPlane(transform.forward, surfaceNormal), surfaceNormal);

[tame thistle]

Thank you!

[scenic forge]

For people that are looking to use additional files in source generators, I took a stab at it and got it working:

• Add -additionalfile:path/to/file to additional compiler arguments.
• Implement OnGeneratedCSProject in an editor script and append <AdditionalFiles Include="path/to/file" /> so it works in your IDE too.
• It doesn't seem like Unity can pick up changes to additional files, you can optionally make an editor script that whenever additional files change, generates a stub .cs with a line of random comment inside to force Unity to recompile and thus rerun SG.

Some unresolved problems I have:

• I could not get generation time dependencies to work with SG, which is really unfortunate because parsing YAML/JSON and generating code based on result is a pretty common pattern.
• Not sure if it's specific to VS Code, it cannot pick up changes to additional files even with source changes. It seems like I have to restart O#.

I'll say what everyone says when they work with SG: "this sucks and could be so much better, but it was still worth migrating to it"

[urban warren]

Is it possible to use an interface as the type for a generic with the struct constraint?

public class Example<T> where T : struct { }

public interface IInterface { }

// Is this possible in some way???
new Example<IInterface>();

[undone coral]

no. what if you implemented the interface in the struct?

do you mean public class Example<T> where T : IInterface, struct

[urban warren]

I need multiple different structs. And I don't own the class Example. It is NativeArray<>

[undone coral]

are you saying you want to have a NativeArray<ISomeInterface>?

[urban warren]

Yes

[undone coral]

okay

you can always cast it to the interface

you can use a struct that implements your interface

then give it to native array

what am i missing here?

what is the specific code you want to have

[urban warren]

This is a bit changed as it is part of a larger system, but basically what I am doing

struct CustomJob : IJobFor, IGenerator
{
  public NativeArray<IGenerator> Generators;

  public void Execute(int jobIndex)
  {
    for(i Generators)
      for (j Generators[i].Length)
        Generators[i].Execute(j);
  }
}

interface IGenerator : IJobFor { }

[undone coral]

i see

why would it be a native array though

what is the advantage here? what am i missing

[urban warren]

You need it to be a native array to use it in a job

[undone coral]

do you mean for it to be a burst job?

why would this have to be a burst job, isn't it delegating to other jobs? potentially themselves burst?

hmm

i see why you are wanting to use IJobFor

i guess this is a little confusing to me, you can declare a static method elsewhere

and use it in your custom job

for the generators

a method and an interface with a single method are duals

jobIndex - where is this used?

[urban warren]

It is required for the IJobFor interface. I also will be using it for passing some specific data to the generators

[undone coral]

oaky

if it's essential to schedule things this way

you can have a native array for each type of input data for the generators (so only structs)

or 1 native array of 1 struct type that is sufficient for all your generators

you would have an enum in that struct that corresponds to which static method you want to execute (i.e., instead of having a generator be a class, it's a single static method)

does that make sense?

[urban warren]

Yeah, I guess that would work. But boy does that feel real ugly

[undone coral]

i think you can also call the jobs directly

instead of via na rray like this

in code

because you're not the only person who wants to run a ton of different jobs all at the "same time"

[urban warren]

What do you mean?

[undone coral]

can't you just schedule each generator

and it will work the same way as what you are doing now, which is trying to schedule 1 job that then calls all the generators via the index

it will work out the same

[urban warren]

How many jobs 'can' you schedule at a time?

[undone coral]

class GeneratorPass : MonoBehaviour {
  List<IGenerator> generators = new();
  JobHandle previousFrameJobs;
  JobHandle nextFrameJobs;
  void Update() {
   previousFrameJobs = nextFrameJobs;
   var handles = generators
        .Select(generator => generator.Schedule())
        .ToArray();

   nextFrameJobs = JobHandle.CombineDependencies(handles)
   // wait for the jobs you scheduled previous frame to complete
   previousFrameJobs.Complete();
   JobHandle.ScheduleBatchedJobs();
  }
}

interface IGenerator : IJob { ... }

@urban warren

you can then all.Complete() in the right place

wherever you want

wherever you need to wait for all the generators to finish

if you have 8 cores, you'll have 8 workers, and they'll start chewing through all the scheduled jobs

[undone coral]

as many as you want

see https://docs.unity3d.com/ScriptReference/Unity.Jobs.JobHandle.ScheduleBatchedJobs.html

[urban warren]

I will explain exactly what my scenario is @undone coral.
I am working on a mesh manipulation thing. I have a stack of modifiers (I called them Generators in my example earlier)
They can be something like "Bend", or they could be "Scatter"

This is where it is getting tricky. "Scatter" creates multiple instances of the mesh, however parameters can be randomized so each instance needs to be generated on its own, not just copied.

So if a "Scatter" modifier creates 10 instances, then all the modifiers above the "Scatter" modifier needs to be executed for each instance.
It gets more tricky because you can have multiple "Scatter" modifiers.
So another one after the first that creates 10 instances of those 10 instances. So 100 instances, and each need to have every modifier run on it.

[undone coral]

i think that's fine

jobs are scheduled and batched onto a queue

you can look at hdrp, it schedules hundreds of jobs sometimes

every frame

the number of jobs isn't super important

you prob want each generator to be an IJobFor of its particular work items

[austere jewel]

I presume you're familiar with Deform (https://github.com/keenanwoodall/Deform)?
I don't remember it having scatter, but it's all about modifiers

[undone coral]

rather than have 1 IJobFor that is your poor man's scheduler

[urban warren]

Nope, but I will take a look. Might be useful! Thanks!

[urban warren]

yeah that is how they are now.
I think I know the 'right' way to approach this now. Thanks for the help!

[undone coral]

did you observe something weird? i don't use jobs often only tweak ones in the hdrp source

so i don't see lots of unusual performance issues

it works how i expect it to, which is "if it's burstable it's fast, otherwise it's a work queue for multithreading"

[urban warren]

No, just trying to figure out how to architect the thing and pass the info I need around in a nice way 🙂

[cerulean sky]

Hello!

I have an issue in my game where UdpClient after some time stops receiving any sort of data at all, and I don't know why

The hosting player has a UdpClient receiving in a loop and and that loops is not broken, it doesn't exceipt, and I can see with wireshark that packets are still coming forth. Yet the .Receive still blocks until timeout and does not catch any data

netstat -ano still shows Unity.exe listening on the correct UDP port, so there's no reason to believe packets are not being transmitted to it

I've spent a few hours yersteday night trying to understand where the problem could be and I can't find it. I get the issue after a few hundreds of packets or so, quite randomly, and once the host is in that state of "not receiving anything" nothing solves it except exiting play mode and playing again. Not even destroying/recreating the udpclient/socket fixes it

Here is my receiving code - which I believe should be catching anything?

            protected async Task Listen()
            {
                try {
                    while (!stopListening) {
                        try {
                            var data = Receive();
                            if (!data.HasValue) continue;
                            [...]
                        }
                        catch (SocketException e) {
                            if (!Game.i.Network.IsMaster) {
                                LowDebug.LogWarning($"Remote killed connection:\n{e}");
                                break;
                            }
                        }
                    }

                    Destroy();
                    LowDebug.LogWarning("Network closed gracefully");
                }
                catch (ObjectDisposedException) {
                    Destroy();
                    LowDebug.LogWarning("Network killed brutally");
                }
                catch (Exception e) {
                    LowDebug.LogError("Error while trying to listen:\n" + e);
                }

                LowDebug.Log($"Broke out of listening loop for {this}!");
            }

            private NetworkMessage? Receive()
            {
                var timeToWait = TimeSpan.FromSeconds(5);
                byte[] data = new byte[0];
                IPEndPoint remoteEP = null;

                var asyncResult = client.BeginReceive(null, null);
                asyncResult.AsyncWaitHandle.WaitOne(timeToWait);
                if (asyncResult.IsCompleted && client != null) {
                    try {
                        data = client.EndReceive(asyncResult, ref remoteEP);
                        // EndReceive worked and we have received data and remote endpoint
                    }
                    catch (Exception ex) {
                        LowDebug.LogWarning($"Endreceive: {ex}");
                        // EndReceive failed and we ended up here
                    }
                }
                else {
                    // The operation wasn't completed before the timeout and we're off the hook
                }

                if (data.Length <= 0) {
                    if (Game.i.Network.TraceNetworkCommunication) {
                        LowDebug.Log($"[network] Receive timeout - nothing was received");
                    }

                    return null;
                }

                [...] // Lots of code to process the data and return it
            }

What happens is that the Receive() call keeps timing out after 5 seconds (as it should when no data is received at all) and returns null. Exactly as if no packets were received. The thing is wireshark indicates there are packets coming in, to the correct port and address, and so they should be caught by Receive (they way they do for a while before it abruptly stops working)

Firewalls on both machines are down so it's not that

If anybody has an idea of what it could be (maybe a unityeditor bug where it eats the packet under some precise circumstance?) i'm all ears

[cerulean sky]

The easiest way I repro it is :

• Both computers (host and client) run the game on unity editor
• Client joins the game, everything works normally
• Client exits play mode (by clicking the ▶ button on unity)
• Hosts sees client stops responding and kicks it out of the party
• Client enters play mode ( ▶ )
• Client tries to join, sends party join packets, but the host is not receiving a single one of them
• Wireshark shows the packets are received by the host machine
• Netstat shows the host machine has Unity.exe listening on the correct port
• Logging on the host machine indicates the UdpClient is up and timing out regularly without any exception, error, or otherwise weird thing

[upbeat path]

You do know that using UDP protocol offers no guarantee that packets will be received and processed or even if they are in which order that will happen

[cerulean sky]

Yes, having written UDP/RUDP network games for the past three years I do know that, but since the packets are actually received on the machine (as Wireshark sees them) I'm figuring out a 100% loss rate between the network driver and the UdpClient is not normal even for UDP and is more likely to come from either my code, a .NET bug, or a unity bug

[upbeat path]

tbh I would break up your Receive method so your while loop knows immediately if that has been received or not and then process that data separately

[cerulean sky]

The behaviour you're describing is the current behaviour of the code I provided

[upbeat path]

Does not look like it from

 [...] // Lots of code to process the data and return it

[cerulean sky]

I'm sorry but the answer "tbh i would break out the code that is not provided and that i imagine being wrong" is not being very helpful to me

[fresh salmon]

Can do that with interruptions in the Animator directly- ask in #🏃┃animation

Oh

[cerulean sky]

Here is the full receive function but I doubt the part I omitted was relevant to the problem I describe

            private NetworkMessage? Receive()
            {
                var timeToWait = TimeSpan.FromSeconds(5);
                byte[] data = new byte[0];
                IPEndPoint remoteEP = null;

                var asyncResult = client.BeginReceive(null, null);
                asyncResult.AsyncWaitHandle.WaitOne(timeToWait);

                return new NetworkMessage(
                    dequeued: buff.Dequeue(),
                    identifier: BitConverter.ToUInt16(new byte[] { buff.Dequeue(), buff.Dequeue() }, 0),
                    data: buff.ToArray(),
                    sender: remoteEP.Address
                );
            }

[upbeat path]

you want your while loop to be as fast as possible. So when you get data in you process that data in a seperate thread if you can rather than blocking this thread which could prevent new packets being received

[cerulean sky]

1. Blocking the network thread does not prevent new packets to be received, the packets are queued in a buffer in the socket stream and no data would be lost if that were to ever happen
2. The issue you point out is irrelevant to the problem that I'm having & describing

[cerulean sky]

Okay I got rid of UdpClient and used C# Sockets instead, still the same issue occurs! With the exact same repro steps

Packets stop coming through

[proven venture]

is there a way to access the raw audio buffer of an audio source? i have a native library that writes little/big endian samples to buffer that i'd love to be able to use with unity's audio mixing (instead of it just writing to the process's audio buffer)

in case you're wondering, i'm using fluidsynth to play back a midi, it's working fine but i'd like it if spacial audio works

[winter yacht]

Do you perhaps remember the client's ip and don't allow them in again as a new player?

[proven venture]

ok, AudioClip.Create with stream=true and the PCMReaderCallback set to

fixed (float* dataPtr = data)
{
  fluid_synth_write_float(_synth, data.Length / 2, dataPtr, 0, 2, dataPtr, 1, 2);
}

it's now working

[cerulean sky]

I want to believe it's something like that but not at all, I don't do such thing & most importantly the server socket is set to listen to *any* address so litterally any UDP data arriving on this port should be caught! (even garbage data)

But I'm definitely feeling like the socket is being turned into some garbage state that prevents it from receiving data, the problem is I can't find how or why and i'm not getting any exception or error

It happens brutally for no reason, and since i'm doing RUDP whenever the host stops "receiving" data it also drops every client because to its point of view no packets get confirmed anymore, so it's very noticeable whenever it happens - and it happens randomly

[calm ocean]

What's the difference between UniTask and UniRx?

I could be wrong but it looks like UniTask has all the reactive programming like UniRx

[lunar raft]

Anyone familiar with the Unity Test Framework? I've tried setting it up but the framework isn't recognizing the existence of my code. "Cannot resolve symbol 'Player'" (Player being a class I defined). I followed the instructions in in creating the assemby but I can't help but feel like there's a step missing.
https://docs.unity3d.com/Packages/com.unity.test-framework@1.1/manual/workflow-create-test-assembly.html

[flint sage]

You gotta add a refernce to your game assembly

[autumn topaz]

how do you get all the agents currently on a navmesh from its navmeshsurface?

[lunar raft]

yeah, I got that impression and there's even an example where one sets up a "GameAssembly" Assembly definition (which the Unity Test Framework docs seems to leave out).

But what I don't know is how the Assembly Definition is associated with the code that I've written. Is it the location of the file? Is it something else? It doesn't seem to be any of the properties in the Inspector values.

[flint sage]

No, you create your own asmdef for the game code

[sly grove]

I believe UniTask is just a revamping of how Unity handles async/await/Task stuff, and UniRX adds the reactive paradigm on top of UniTask

[lunar raft]

Yes, but I don't know how to configure the asmdef so it references my game code. That's what I'm asking.

[sly grove]

yes it's the location of the asmdef file

the file grabs all source code within the directory it's in (and subdirectories) and puts them in an assembly

[lunar raft]

Right.. so I can't have my test scripts in my game scripts folder. I need to organize my Asset folder a little differently. So that the asmdef for the tests isn't overlapping the game asmdef.

[flint sage]

Yes

You also shouldn't be shipping tests with your game hence the distinction

[sly grove]

correct

[lunar raft]

The Unity documentation is kind of light on these details. I'm gonna go make the suggestion that they update them.

[undone coral]

what's your objective?

it's one of those things where i look at the source and it would be easier to rewrite this little part to do the thing you want, instead of trying to understand how what you've written might have this weird bug

[lunar raft]

@sly grove @flint sage Thank you. 🙂

[last acorn]

Hello. My first msg here 🙂 i'm wondering if anyone went through the process of migrating their project from built-in assemblies to asmdef?
Specifically i'd like to know about compatibility with existing asset bundles (i assume that this transition breaks their compatibility with the built player).

I also asked it on the forums with greater detail - https://forum.unity.com/threads/migrating-asset-bundles-from-assembly-csharp-to-asmdef.1352294/

[undone coral]

asyncResult.AsyncWaitHandle.WaitOne(timeToWait); why are you doing this? @cerulean sky

[undone coral]

i think it's best to test, but afaik the GUIDs of the scripts do not change, so it should work fine

[tame thistle]

Sorry if wrong chat, but if i am trying to make a character controller using raycasts so that the character can walk up walls + walk around a 3d cube, what would the best setup of raycasts + method to determine the normal?

[last acorn]

From what i remember, bundles keep a reference by name to the script, for example we once moved a class to another namespace and the asset bundle was broken due to a missing script

[undone coral]

then i guess you can't use asmdef if you already know that it doesn't work

[last acorn]

i thought maybe someone went down that road before

[undone coral]

i think you would have to contact a unity support person to get a definitive answer. here is a thread illustrating the confusion on the matter: https://forum.unity.com/threads/asset-bundle-cannot-find-scripts-from-assembly-definition-files.531804/

they're going to tell you to test

good luck out there 🙂

i see the GUIDs are stripped, so it will still be buggy imo

imo, don't use asset bundles across versions @last acorn

[old swallow]

Hey, anyone have any clue how to reset prefab variables?

Resetting added / removed GameObjects and Components was supper easy with "PrefabUtility.GetAddedGameObjects()", "PrefabUtility.GetAddedComponents()" and "PrefabUtility.GetRemovedComponents()".

But there is nothing like that for component variables! There is "PrefabUtility.GetPropertyModifications()" but it returns "PropertyModification" witch has no "Revert()" function and the "RevertPropertyOverride()" accepts only "SerializedProperty"!!!!!

I have been trying to do this like 2h now and the Unity documentation is literally useless with all of these functions?!?!?!?
Here is the code: https://pastebin.com/eFQZRG8e

[jolly token]

You can create SerializedProperty from object and property path, which is in modification, so..

[old swallow]

yeah but how do i get the object

i tried to use the "PropertyModification.target"

but something was wrong with it

[jolly token]

new SerializedObject(target) ig

Then find with path

[old swallow]

This just trows a bunch of errors:

foreach (var item in UnityEditor.PrefabUtility.GetPropertyModifications(RootObject))
{
     var serializedobject = new UnityEditor.SerializedObject(item.target);
     var serializedProperty = serializedobject.FindProperty(item.propertyPath);

     UnityEditor.PrefabUtility.RevertPropertyOverride(serializedProperty, UnityEditor.InteractionMode.AutomatedAction);
}

"ArgumentException: Calling apply or revert methods on an object which is not part of a Prefab instance is not supported."
but i have an idea how to fix it

[old swallow]

Nope "UnityEditor.PrefabUtility.IsPartOfPrefabInstance(item.target)" always returns false

[jolly token]

Hmm alright maybe log what value the target is

[old swallow]

Seems to be the gameobject the components are on

for each changed field

[jolly token]

Btw Is there reason that you cannot use RevertObjectOverride or RevertPrefabInstance?

[old swallow]

yes and no

before I just looped through every object and reset changes but it had a side effect of making the icons in the hierarchy disappear and not allowing me to rename the objects in hierarchy

this function is run every frame

so resetting changes made hierarchy refresh a lot

thus the side effects

now im thinking about finding the changes and only if they exist resetting them

i might be overthinking it again like usual lol

[jolly token]

What is RootObject here, is it prefab instance?
Is PrefabUtility.IsPartOfPrefabInstance(RootObject) true?

[old swallow]

"What is RootObject here, is it prefab instance?" yes

[jolly token]

Huh I'm not sure why it have to run every frame

[cerulean sky]

what do you mean? where is it not doing the thing I want ? 😮
I rewrote it in the meantime to use sockets anyway

            private NetworkMessage? Receive()
            {
                byte[] buffer = new byte[2048];
                EndPoint remoteEP = new IPEndPoint(IPAddress.Any, IPEndPoint.MinPort);

                int bytesReceived = socket.ReceiveFrom(buffer, ref remoteEP);
                if (bytesReceived <= 0) {
                    if (Game.i.Network.TraceNetworkCommunication) {
                        LowDebug.Log($"[network] Receive timeout - nothing was received");
                    }

                    return null;
                }

                // Truncate
                byte[] data = new byte[bytesReceived];
                Array.Copy(buffer, data, bytesReceived);

                return new NetworkMessage(...);
            }

            protected async Task Listen()
            {
                try {
                    while (!stopListening) {
                        try {
                            var data = Receive();
                            if (!data.HasValue) continue;
                            if (Game.i.SimulateBadNetwork && new Random().NextDouble() < 0.3f) continue;

                            [...]

                            _ = Task.Run(()=> onReceiveData?.Invoke(data.Value));
                        }
                        catch (Exception e) {
                            LowDebug.LogError("Error while trying to listen:\n" + e);
                        }
                    }

                    Destroy();
                    LowDebug.LogWarning("Network closed gracefully");
                }
                catch (ObjectDisposedException) {
                    Destroy();
                    LowDebug.LogWarning("Network killed brutally");
                }

                LowDebug.Log(...);
            }

problem is still exactly the same! The socket stops "hearing" data even though it's still listening, after some random while

[old swallow]

its because i didnt find a better way to trigger it

the point of the script is to make sure an object never has overrides

ever

and i also hide the children using "hideFlags"

[jolly token]

Hmm not sure why this would be false if it returns true with Root

[old swallow]

no idea seeing that "item.target.name" seems to be the names of the GameObjects holding the components

[jolly token]

OnValidate can cover some cases but "to make it never has override ever" sounds tough
I wish there was built in feature like that lol.

'Lock' instance except some property or such

[old swallow]

Here is the full code:
Runtime script: https://pastebin.com/RaHnRw6i
Editor script: https://pastebin.com/bvJLH5jk

[old swallow]

yeah at this point i have a few bodges that make it somewhat work

the prefab script runs every time gizmos get drawn and every frame if the component is at least once not collapsed

[jolly token]

Hmm maybe it is something to do with hideFlags and it cannot recognize child object?

[old swallow]

probably not bacause i disabled hideflags while testing

with hideflags i cant even make the overrides

but just in case i still want to reset them

@jolly token bruh...
"GetObjectOverrides" that function works just like the other 3 that were easy but works with variables

dumb unity

no

no no no

dumb me

well...

thx for the help anyways

        private void RevertChanges(GameObject RootObject)
        {
            foreach (var item in UnityEditor.PrefabUtility.GetAddedGameObjects(RootObject))
            {
                item.Revert();
            }

            /*foreach (var item in UnityEditor.PrefabUtility.GetRemovedGameObjects(RootObject))
            {
                item.Revert(); // You can't remove GameObjects from prefabs anyways
            }*/

            foreach (var item in UnityEditor.PrefabUtility.GetAddedComponents(RootObject))
            {
                item.Revert();
            }

            foreach (var item in UnityEditor.PrefabUtility.GetRemovedComponents(RootObject))
            {
                item.Revert();
            }

            foreach (var item in UnityEditor.PrefabUtility.GetObjectOverrides(RootObject))
            {
                item.Revert();
            }
        }

this workd perfectly

[jolly token]

Oh nice 😌 So it remains mystery why property modification target is not part of prefab instance

[old swallow]

hahaha

I guess so

[calm ocean]

In UniRx, if I subscribe to a reactive property, am I also responsible for disposing? For example

        private void OnEnable()
        {
            _virusReactivePropertyDisposable = _virusReactiveProperty.Subscribe(_playerVirusMeterUI.SetVirusPercentage);
        }

        private void OnDisable()
        {
            _virusReactivePropertyDisposable.Dispose();
        }

Is the on disable here necessary?

For context, this is inside a MonoBehaviour

[jolly token]

Yes, it is necessary. Otherwise you can subscribe multiple times.
However you can use TakeUntilDisable(this) or AddTo(this) to make your code cleaner

If the reactive property itself is disposed or GC'd, then you don't have to dispose subscriptions.

For UI update I prefer using CompositeDisposable so I can clear related subscriptions at once before resubscribing

[calm ocean]

Ah I see, so take until disable is just an operator that does what I did above with the indisable and the add to this disposes when the game object is destroyed right?

[jolly token]

Yes

[shut owl]

Hi, so I am trying to create ai and it was going fine but now I have problem after adding some stuff that allows for the enemy to move towards the player when the player enters their FOV. The code also includes stuff that allows for the enemy to go to specific locations. the problem now occurs when the enemy can see the player and I cant find a solution. The console reads that the operation caused a stack overflow. if you think you can help me, please dm me. Its easier that way for me.

[pliant crest]

chances are no one will give you private help

stack overflow is when you recursively call a method too deep

[shut owl]

@pliant crest Thank you for the reply. Thank you for telling me what a stack overflow is. I found the problem because of that and now everything is working the way I need it too

[mint sleet]

Is it possible to make a newer commit to the initial commit of the repo?

I do not want to see others than the marked version. (I know that creating a new repo and pushing it into it is a solution, but I want to learn if it is possible)

[long ivy]

squash the commits using interactive rebase. As long as nobody else has the history (it sounds like they don't), you can rewrite history this way

[lofty quail]

Hi,
I remember a website with a huge checklist to improve performance. I didn't remember the name, do you have any idea ?

[elfin bone]

Milanote?

[lofty quail]

No I think that was : https://thegamedev.guru/unity-performance-checklist/

But now that isn't free anymore

[turbid tinsel]

Hi, is there a way to write something similar to
using Random = UnityEngine.Random;
but for 1 method only? Instead of an entire class?
I want it specifically for

using SizeOf = System.Runtime.InteropServices.Marshal.SizeOf;```

which is a method

I need it because I have no clue how to name System.Runtime.InteropServices.Marshal...

[orchid marsh]

Why not Marshal?

[austere jewel]

What do you mean? Is there a reason to not just using System.Runtime.InteropServices;?
And do Marshal.SizeOf?

You can call using static System.Runtime.InteropServices.Marshal; to import all the members of that class, but it can muddy the water and sacrifice clarity

[winter yacht]

In the case of Random it's helpful else you have to specify either System.Random or UnityEngine.Random in the code. This happens if you have both using System and using UnityEngine.

[turbid tinsel]

I'm never using System.Random anyway, but that's not my problem here

[turbid tinsel]

that's the one I ended up using, thanks!

[winter yacht]

I know, but Random will now automatically be the correct one of the two.

[rugged radish]

Does ComputeBuffer.SetData perform the work at the moment you call it, or it just puts the copying operation into some queue to be executed later with the next Dispatch ?

[turbid tinsel]

It does it immediately as far as I know

Also, there's a lot of overhead, so 3 calls are MUCH slower than 1 call with 3 times more data

even if they're right one after another

[turbid tinsel]

.

[rugged radish]

thank you, very useful to know 👍

[undone coral]

@turbid tinsel use this approach, except if you really need to cut off the rest of the symbols in Marshal, create your own static class with static methods and use the inlining attribute.

[indigo citrus]

Hello I had to ended task the unity after doing something I didnt want to while it was loading and I think the scene got corrupted or something

The scene will keep like this

[regal olive]

is this when u enter play mode?

[indigo citrus]

No

I forgot to say it

Its when I try to enter in the scene

I am in another scene and when I double click it boom just stays there

Something that before would just take a few seconds doesnt load at all

I can send the scene file if needed

[regal olive]

no idea but u might want to check if the backup scene has it

@indigo citrus https://forum.unity.com/threads/unity-hangs-when-opening-project-in-visual-studio.1233787/

[indigo citrus]

Backup scene?

[harsh oyster]

Uhm how come the terrain layer is very faintly painted??

[indigo citrus]

Just checked and I think that there's none cause I restarted the unity ;-

The scene just doesnt open

[cinder cargo]

hi, im making a dungeon, but when It generates the rooms can generate inside of other ones, I tried making a trigger collision (and normal collision) detection to check if it could spawn but I couldnt get it to work. Is there any other way to stop generation if its inside of another object?

not sure if this is the right area to ask this question...

[compact ingot]

either you check after the fact or generate such that overlap is impossible, no other options exist. Physics are a convenient abstraction to do it. Other option are more work.

[cinder cargo]

so simply doing this as it generates isnt an option?

[compact ingot]

You’d not use that api

[sly grove]

"OnCollision" is not a thing in Unity, even less so inside another function.

This is kinda #💻┃code-beginner or #archived-code-general stuff tbh

[cinder cargo]

yeah i posted it in here without realizing at the time

[flint sage]

Also please set up your ide correctly as #854851968446365696 describes

[cinder cargo]

also I had it at OnCollisionEnter and it didnt do anything either

[compact ingot]

You’d use this for your use case https://docs.unity3d.com/ScriptReference/Physics.ComputePenetration.html

[cinder cargo]

ok ill check that out thanks

[grizzled lake]

Is there a Unity API call to get a collection of the available tags in the project?

I can use this in the editor:
UnityEditorInternal.InternalEditorUtility.tags but I don't think it's available at runtime.

Is there a runtime version?

[sly grove]

I don't think so but usually if you are looking for this functionality there's a better way to approach the problem than tags

[rigid dagger]

I am having a problem with some play mode tests, I would like to completely, completely reset my scene between tests, but I have some problematic DontDestroyOnLoad objects set by some third party packages (and possibly static fields as well). Anyone know how I can deal with this?

[jolly token]

I'm afraid that you'd need to manually reset the states 🤔

Unless you run test separately per scene

[rigid dagger]

I'm fine doing a scene reload, but the Dont destroy on load objects hang around still.

[jolly token]

I mean you'd need domain reloading to reset static variables

[rigid dagger]

Yeah, and I'm assuming that is just impossible

[jolly token]

So either manually reset your static states
Or execute each test separately (not just loading other scene)

I think second option could be automated but with painful and long process 😌

[rigid dagger]

Yeah, it will likely be running each independent

Yeah agreed

I'm almost making my own test runner at that point

[jolly token]

So it might be better to just have common static method to destroy all DDOL objects and reset static variables

And run that before each test

[rigid dagger]

I think I'll look at that. I halfheartedly tried destroying the ddol objects at one point but I'll revisit that.

[regal olive]

Hello people.

I have this rope simulation I have been trying to make which resembles the one from Profundum (2019): https://forums.tigsource.com/index.php?topic=64389.msg1389271#msg1389271 -- this system uses several connected rigidbody capsules connected with Configurable Joints, as has been used by the devs of Profundum themselves.

The main aim is to make sure I am able to make knots on this rope.

In my case, I have made it so that the rope segments are spawned with a bias so that the simulation doesn't jitter. However, this causes the rope segments to slip through the spaces between segments, essentially making it impossible to knot the rope. I haven't been able to get rid of the spawn bias without destabilising the simulation entirely.

The configurable joints are set up exactly in the way as shown in the devlog post.

The capsule and rigidbody data are in the screenshots below.

Additional Details
The project uses the Oculus VR Interaction SDK and as such has some other components on it. I have kept the Physics Grabbable component disabled as it causes my segments to become unresponsive to grabbing entirely. However, in every other way, this part of the simulation is working as expected.

Capsule Collider

Rigidbody

A single segment.

Rope segments in arrangement in and out of play mode -- notice the gap between each segment.

[wooden bronze]

How can I save a collider of any type to a variable and then spawn a new object with that exact type and values. Seems like you cant just use Collider because then it down casts and removes all of the info (like the mesh for a mesh collider) and on top of that I dont think it saves its type so I cant just add component with the same type as it. Do I have to just make a variable for each collider type and then check which ones are null and which ones it filled in?

because that seems redundant

[kindred tusk]

You can use Collider as the variable type, it will still be there, it just requires casting to access the fields that aren't included in the base type.

Maybe if you share the code you're stuck on it will be easier to answer your question.

You can't instantiate a component on its own, you need a gameobject.

[wooden bronze]

here one sec

saves each object to this struct

public struct TickCollider
    {
        public Vector3 position;
        public Vector3 rotation;
        public string tag, layer;
        public Collider AttachedCollider;
    }

[kindred tusk]

That's not a collider, it's a struct.

Oh, I see.

[wooden bronze]

then I loop over each struct and need to spawn a gameobject with the same collider values

[kindred tusk]

You can do this if you want:

public struct TickCollider<T> where T : Collider {
  public Vector3 position;
  public Vector3 rotation;
  public string tag, layer;
  public T AttachedCollider;
}

[kindred tusk]

Ah...

You need to show the whole code

Like where exactly is the line where the problem arises?

Because what you have should work

[wooden bronze]

just in adding the correct collider to the object

and then copying over the values (just need to do each one so easy)

[kindred tusk]

foreach (var t in tickColliders) {
  var instance = Instantiate(t.AttachedCollider, t.position, t.rotation);
  instance.tag = t.tag;
  instance.layer = LayerMask.NameToLayer(t.layer);
}

That will be fine

[wooden bronze]

really?

will try

[kindred tusk]

What were you trying before?

[wooden bronze]

someone typeof thing I couldn't figure out

with trying to add a component to a new gameobject where that component matches the type of the AttachedCollider

[kindred tusk]

So... are you trying to instantiate a new object or attach a new collider to an object?

And does the object have a rigidbody?

[wooden bronze]

no

just need the collider position and mesh and size and stuff

[kindred tusk]

what is this in response to?

[wooden bronze]

no rigidbody

[kindred tusk]

so...

[wooden bronze]

new object and then attach a new collider to it with the same values as the AttachedCollider

[kindred tusk]

Okay.

Did you consider making the colliders on child objects?

Then you can just duplicate the child objects

If you attach a kinematic rigidbody it will treat the colliders as if they're on the root object.

That's the easiest way to do it in Unity

Duplicating individual objects is hard

Colliders don't have tags or layers, so it doesn't really make sense

What you're doing

And certainly isn't #archived-code-advanced for future reference

[undone coral]

The main aim is to make sure I am able to make knots on this rope.
maybe ask for the source from profundum

[wooden bronze]

lag compensation for multiplayer, basically saves all networked objects colliders each tick and then on the clients request (such as for shooting) tells the server I shot here, then the server sees how far the client is behind it, goes back to that tick, spawns the colliders, does the raycast hit stuff on the server side and passes back the hit info to the client

[kindred tusk]

Okay, so make one object for the physics palyer, and one for the view.

When you want to resim the shot, move the physics player back to its old position, then bring it forward to its "current" position before running the next input frame

You shouldn't need to construct new objects for that

[regal olive]

This is a college assignment, so perhaps that's not an option? Besides it looks like they are still making money from the game so they'd decline the request anyway.

[gray zinc]

Is there any way to store System.Action<InputAction.CallbackContext> in a terser delegate? I tried making a delegate "delegate void ControlAction(InputAction.CallbackContext context)" but when I tried assigning it to an InputAction it said it couldn't cast ControlAction to System.Action<InputAction.CallbackContext> (even though the parameters are identical)

Basically I'm trying to shorten a really long Action<T> by storing it/aliasing it in a named delegate (e.g. MyDelegate instead of Action<Really.Long.Parameter.Name>)

Also, I don't need the shorter name delegate to be generic because it'll only be InputAction.CallbackContext as the parameter for the action.

I'm currently just using an alias "using MyDelegate = Action<blah blah>" but if it would be possible to declare a delegate inside my namespace and then just use that instead of having to put the alias in every file I want to use it in that would be much better.

[random dust]

I don't think you need to reference it as an Action at all

So just assign your delegate to the ControlAction instead of assigning it as an Action and storing that as the ControlAction instead

[regal olive]

Could someone please help me make the rope segments not slip through each other's gaps?

EDIT: Wording.

[misty walrus]

Is anyone familiar with implementing custom android themes? I have this:

<resources>
    <style name="CustomTheme" parent="@android:style/Theme.NoTitleBar.Fullscreen">
        <item name="android:windowBackground">@android:color/black</item>
    </style>
</resources>

in a file next to my androidmanifest. This line <application android:theme="@android:style/CustomTheme" in my manifest file is causing an error. error: resource android:style/CustomTheme not found. I couldn't find any documentation online so I'm not sure how I can make my custom theme accessable.

[hazy hearth]

Hello there, I've published a title that I've been working for a year and through that process I've managed to learn plenty of c# tricks and skills. Although I am embarrassed to say that even now I do not quite understand how for instance something like this works (programming wise ):

Something.ContinueWith(task => {
          ...            
});

Do you guys have any tutorial in order for me to understand code that goes beyond the loops and the ifs ?

[flint wraith]

i dont understand them after 10 years yet use them 😂

[hazy hearth]

I use them and everything works fine, especially with firebase and other plugins but you know 😛 I'd like to understand the flow of the code when I debug

https://www.youtube.com/watch?v=3cfVmcAkR2w&list=PL4LFuHwItvKaOi-bN1E2WUVyZbuRhVokL&ab_channel=GavinLon

I've found this one and maybe I'll give it a try

[misty walrus]

As in lambda functions or the method ContinueWith itself?

[gray zinc]

unfortunately I have to reference it as an Action because otherwise the InputSystem complains

[random dust]

Hmmm

Then you might be limited to using an Action

[undone coral]

maybe use friction

i didn't read the forum thread super carefully. you might have to dynamically change the friction of rigidbodies participating in a knot?

[undone coral]

i'm not sure if a global using is supported

this sounds low stakes though

[alpine adder]

does anyone have experience with linker errors with unity cloud build and xcode?

[undone coral]

not specifically with unity cloud build but with all automated building

linker errors are generally not related to the build server. it sounds like you didn't check something in, or you aren't 100% sure how to include a library or something like that

[shadow spear]

yoo

can someone tell me how do i change the project settings in the game using code during run time

does anyone know how to do that

[undone coral]

what specifically do you want to change and why?

this also sounds #archived-code-general / #💻┃code-beginner

[shadow spear]

KK

[honest hull]

Hey does the raytracingshader actually use the rt cores?
from my basic tests so far it seems that my custom computeshader rt solution outperforms it which doesnt make sense

and is there much delay when interoping between compute shaders and raytracingshaders?

[undone coral]

what is RayTracingShader? you can check out the ource and see if it uses the accelerated rt structures

those only exist on PS5 and DX12

[honest hull]

raytracingshader is I believe how you access the hardware RT functionality
and ye im on dx12

[undone coral]

i don't know very much about unity's specific implementation sorry 😦

[honest hull]

ok thank you!
theres very minimal documation on it

[alpine adder]

so im trying to figure out how to go about this with cloud build. im not sure what files would be missing here is exact errors. im not sure why it can't find architecture for a cloud build server

[undone coral]

are you developing on an intel or apple silicon mac?

and is this the only error it gives you?

[alpine adder]

I am doing a cloud build on mac and these are the main ones they all seem to just relate back to these logs

I can send the full file if that is helpful?

[gray zinc]

yup apparently not. I ended up just making a helper function to create the arrays I wanted to make using params. That way I don't have to write the new System.Action<InputSystem.InputAction.CallbackContext>[] every time I want to create an array of Actions.

[undone coral]

hmm so you're saying you are trying to develop for mac/ios without a mac?

i understand you're doing a cloud build

i think if you want to develop for iOS without owning a macOS device, you shoudl file a ticket with cloud build support

[sage radish]

Global using and aliases are possible in C# 10.0, but Unity only supports C# 9.0

[regal olive]

I have applied a physics material but it doesn't help prevent the slipping-through problem.

[regal olive]

No, it looks like just having a static setting should be sufficient for now. However, the participating segments must at least remain in the knot configuration.

[undone coral]

did you try making the friction really high?

[regal olive]

Let me test that right now!

Trying out dynamic friction = 50, static friction = 10

@undone coral no, the intended problem is not getting solved.

Let me try to extract a video of the scene for you.

[undone coral]

it's okay you don't have to do that

i'm not sure how to address this issue, i'm sorry

[regal olive]

No worries. I was intending to record a video of the issue anyways!

I'll just put it here for anyone else, and forward it to other servers and my faculty.

Here's a video of the problem I am having.

[scenic lark]

hey everyone. is there any way to run this script with lower fps than time set in unity? It's reflection but when it runs in 30 fps, it eats alot of gpu power.

[abstract folio]

it looks like alot of the stuff you have in OnWillRender could be moved into a coroutine that only runs a few times per second, rather than every frame. I suspect this may cause a short lag in the reflections- but it sounds like you might be ok with that. You mentioned GPU power gets sucked up- but I'm not sure if such a change would help with that (but it WOULD help reduce CPU usage).

check out this for the coroutine stuff https://docs.unity3d.com/ScriptReference/WaitForSeconds.html

[scenic lark]

Thanks

[abstract folio]

this looks to me like the links are slipping between the spaces between links. If you increase the connection force between the links, and reduce the space between the links, does that help at all?

[undone coral]

why does this field have no side effects in git?

what is the lighting data asset reference? where is this? why isn't it saved?

it seems to get cleared every time it is set

[sly grove]

it's where baked global illumination data is stored

it's a file generally shoved in a folder next to your scene file.

You might have it .gitignored

[undone coral]

i resolved the issue by deleting the reference to the lighting settings in the scene tab, saving, closing, reopening, reassigning lighting settings, then reassigning lighting data asset

now trying git clean -dxf and seeing if the reference is kept

@sly grove any idea where this reference might be stored in code? i think i have to do a [RuntimeOnLoad] and patch it up whenever the editor is opened with this scene

because there are too many quirks with it, potentially on different editor platforms

i guess this Lightmapping.lightingSettings

[undone coral]

do objects in Resource transitively include their dependencies?

[smoky glade]

Halo
Is there anything i can use around yield return SceneManager.LoadSceneAsync that returns the scene when it's loaded?
Without using SceneManager.sceneLoaded callback whatsoever?
Bcoz i'll have scenario where i'll load the same scene additively multiple times at the same time

[jolly token]

The result of LoadSceneAsync is AsyncOperation which has completed callback

So you can use it instead of yielding it

[undone coral]

well setting the lightmapping is going to be a nightmare

[jolly token]

It is nightmare 😄 and depends on "scenes"

[smoky glade]

So on complete, how do i access the loaded scene? Still use SceneManager.GetSceneAt or the likes?

[undone coral]

why is the lightingdata.asset a binary file..

[jolly token]

Yeah seems like there is no good way to fetch the reference, that's lame 🤔

[smoky glade]

https://forum.unity.com/threads/how-to-get-the-scene-loaded-by-scenemanager-loadsceneasync.1044790/
I guess to be completely certain, have the calling process claim a loaded scene by having a component in the scene hold a bool taken
And during any sceneLoaded (or async.complete), gotta go thru all of the scene with same name and check if the component is claimed, else check the next one

[humble onyx]

the same reason that texture data is binary.
text only makes sens if you have readable content and the lightbaked data is not text readable

[timber remnant]

I have camera smooth movement from somewhere else, how do i make it in my script?

private void HandleMouseLook()
    {
        rotationx -= Input.GetAxis("Mouse Y") * lookSpeedY;
        rotationx = Mathf.Clamp(rotationx, -upperLookLimit, lowerLookLimit);
        playerCamera.transform.localRotation = Quaternion.Euler(rotationx, 0, 0);
        float mousex = Input.GetAxis("Mouse X") * lookSpeedx;
        transform.rotation *= Quaternion.Euler(0, mousex, 0);
    }

this is the look code

[undone coral]

isn't it just a bunch of references to files...

i'm not talking about the image data

it just goes to show how confusing and awful their lightmapping system is

[humble onyx]

where do you think is the light probe data stored

[undone coral]

i guess it's in there

[humble onyx]

at least as far is i know

[undone coral]

it's okay, i am writing a different workaround for this quirk

[humble onyx]

the only other data file that is binary is the terrain data

[undone coral]

patching the scene on build

it's possible to get into enough jeopardy in the unity editor to save the scene with that field populated

close the editor, reopen the editor, and observe that field is empty

it's an editor bug i'm sure, but not one that i have the time to create a reproduction for unity QA, or to wait 9 months for them to fix it

[mint sleet]

what is the problem here! Its everydays problem with damn charging cable. And so realistic that might make people go crazy

[viral knoll]

how do you guys code the max exp so it doesn't go way up to the sky

[lyric dragon]

Hello guys!
I am currently implementing a plugin for android and I have a method that has to be run on the main thread. So I am using something like:

private void Start() 
{
  AndroidJavaObject activity = **init**;
  activity.Call("runOnUiThread", myFunc);
}

private void myFunc()
{
  // something to be run on the main thread
}

private void anotherFunc(int number)
{
  // do something with number
}

[smoky glade]

Hi all
Bumping this bcoz still having problem..
So i'm using Scene.GetRootGameObjects inside the SceneManager.sceneLoaded callback, but it says ArgumentException: The scene is invalid
So now i'm lost again. Is SceneManager.sceneLoaded getting called before scene is valid? I read it's invalid on MB.Awake, and valid on Start. So i guess sceneLoaded is before Start?

[smoky glade]

Not sure if this is by design, but it'd be nice to have a more reliable version of SceneManager.sceneLoaded

[gaunt reef]

I have a Unity project and I want it to export and intergrate it into react native app, it worked well on android and IOS but I wonder if I can export an unity project to intergrate it into windows react native app?

both android and ios I exported as library to intergrate into android & ios, I tried exported it as WebGL but it appear that interaction between app and game won't be as good with this solution

So can unity export the project as a library and intergrated into react native Windows app like android and ios?

[regal olive]

I will try that but it will likely just destabilise the simulation by causing the rope segments to jitter.

[regal olive]

Charging cables usually don't slip inside each other 😛

[mint sleet]

my cable does 😄 @regal olive

[regal olive]

@abstract folio also, for your reference, here's the original post.

[lament salmon]

so your problem is the capsules slipping thru the gaps in between?

you could make the capsules overlap and disable collision in the joint, so that a segment doesnt collide with the one next to it.

changing the rigidbodies' collision detection mode might also help.

[regal olive]

I seriously doubt if it will keep the simulation stable. Still, worth a shot.

[lament salmon]

can also up the Default Solver Iterations and Default Solver Velocity Iterations in the Physics settings

I had to go from default 6 to like 32 for stable ragdoll simulation

Enable Adaptive Force might help too

[hazy hearth]

How do I yield until a method is finished?

yield return InternetManager.instance.CallCheckConnection();

CallCheckConnection return void so I have an error

[random dust]

You can use an async-await method instead

Make both methods async, where the CallCheckConnection is a task. Await the method

The CallCheckConnection obviously needs to properly implement the async-await pattern

[hazy hearth]

Let me explain the problem before I proceed to changes.
As of right now my code is like this:

// Internet check
InternetManager.instance.online = false;
InternetManager.instance.CallCheckConnection();
yield return new WaitUntil(predicate: () => InternetManager.instance.online);

// AD            
RewardedAd rewardedAd = adManager.GetComponent<RewardedAd>();
rewardedAd.ShowAd();
yield return new WaitUntil(() => rewardedAd.hasFinished);
            

Whenever the player dies for the first time an internet check starts and waits until the player is connected to the internet. In case the player is offline, CallCheckConnection() shows a Try again button to check for internet again, until the player is online.

Then an ad is properly showed and I get the big money.

The thing is that my users complained about the mandatory internet connection so I was thinking of removing it. In order to remove it I need to make the panel not show up in the first place. So I need to make an internet check only to make decision whether to show the 'Watch an ad to continue' or not.
@random dust

[regal olive]

I'll let you know about these changes soon, say another 6-7 hours from now 😅

[dapper cave]

how do i get the GUID or path of a script's type?

[sly grove]

what are you trying to do with it?

[dapper cave]

getting the path where the script is so that user can move the folder around and still link to the data

[sly grove]

https://docs.unity3d.com/ScriptReference/MonoScript.FromMonoBehaviour.html ?

combined with... https://docs.unity3d.com/ScriptReference/AssetDatabase.GetAssetPath.html

[dapper cave]

very cool - thanks

[dapper cave]

is there a way to do that from a type instead?

[wispy terrace]

What's the best Steamworks wrapper for unity?

[sly grove]

Since scripts need to be named the same as the type name you can do:

string assetGUID = AssetDatabase.FindAssets<MonoScript>($"{nameof(SomeType)} t:MonoScript")[0];```

[dapper cave]

I see, I'll try that. is that the case with editor script too?

[jolly token]

Editor script is not MonoBehaviour, I don't think unity associate GUID for editor script classes.

[flint sage]

Any file in the project has a GUID

And all of the scripts are MonoScripts

[sly grove]

no because there's no enforcement of filename == class name for editor scripts

[jolly token]

I'm saying "they are not associate GUID with the class in the file"

[flint sage]

Right yeah, misunderstood then

[pale pier]

Anyone know how I can Reset a scriptable object from code?

Couldn't find how Unity were doing it from the CsReference repository

[obsidian glade]

something could work along the lines of:

AutoPreferences mySO;
typeof(AutoPreferences).GetMethod("Reset").Invoke(mySO);

[pale pier]

That won't work unfortunately, that would only invoke any custom Reset method I had on that script.

The best I could come up with was using

ScriptableObject.CreateInstance
to create a new object and then use

EditorUtility.CopySerialized
to copy properties from it to the original object.

It "works" but I thought there would be a more straight forward option.

[misty walrus]

Does anyone know how I can serialize an Object ? Much like in the UnityEvent, I need a field where I can chug in any object whatsoever.

[sage radish]

You can serialize UnityEngine.Object. If you want to serialize System.Object, your only option is to use [SerializeReference].

[misty walrus]

Oh I'm dumb, tyvm!

[misty walrus]

Is this kind of popup public for usage?

[elfin bone]

Yeah so like the Method should be public to be shown in the popup dropdown

[flint sage]

You want that style of popup? https://docs.unity3d.com/ScriptReference/GenericMenu.html

The sub menu's are just strings with / in them

[subtle moon]

Hey! Quick question about the timing of collisions. In the .gif you can see black balls being spawned at set intervals. The spawning is triggered from a function that has been called with InvokeRepeating. The Debug.Log:s show the time between when the previous ball and the current ball hit the green square. My question is, why does the timing fluctuate? Is there any way I could “quantize” the time so that it is consistent?

[misty walrus]

I think what I'm looking for was this: https://docs.unity3d.com/ScriptReference/Experimental.GraphView.SearchWindow.html.

[tropic pulsar]

You can make a consistent simulation if you are updating the object yourself. Physics (as far as I know) is not deterministic in Unity. Meaning similar inputs result in varying outputs.

What you are seeing is compounding floating point error.

Why do you need consistent timing?

Tbh, timing is almost the same

[subtle moon]

Thanks for the reply! Thing is, those marbles will be bouncing and rolling all over the place so doing my own physics calculations for them would probably be too hard for me at my current skill level. I need consistent timing because the green box plays back audio when it's hit, and the idea is that this app could be used a sampler/sequencer lol

I have already tried building drum loops with this, and the fluctuation is audible.

[tropic pulsar]

You are taking wrong approach, if you want consistent timing for anything do not use physics.

My recommendation is to change design to have "simpler" physics and to implement it yourself. Preferably using integers for positions rather than floats to avoid floating point error.

[subtle moon]

Being physics based is kind of the point of this, if that makes consistency impossible then I will just have to live with it hahah

Thanks, will look into that!

[tropic pulsar]

Well, you need to give us the bigger picture but the short answer is "No". 😄

[tender light]

You can decrease this variation by increasing the simulation frequency. Maybe instead of 50hz try.... 300hz?

[tropic pulsar]

Meaning physics and consistent timing do not mix well

Yeah, that is good idea, play with physics settings, increase simulation resolution for example.

[subtle moon]

Cheers! I'll try, doesn't have to be really perfect just enough to not be audible.

[tender light]

InvokeRepeating does not have sub frame precision. You can write your own that's more precise. And then simulate physics manually
look into https://docs.unity3d.com/2020.1/Documentation/ScriptReference/PhysicsScene.Simulate.html

[tropic pulsar]

Another idea yeah, maybe update your simulation manually.

[tender light]

But that's more involved and complicated. Maybe more than you need? Simulation frequency increase might be good enough

[subtle moon]

That looks super promising actually. I'll look into that as well and see if I can wrap my head around it, but let's start with simply increasing the simulation frequency.

That seems to have done it! A fixed update now happens 5 times as often as previously, hope I can keep things optimized enough to not run into issues.

[tropic pulsar]

Sounds promising.

[tender light]

Depends on your target platform.
I would recommend you clean out your layer collision matrix try to keep your actually colliding layers as minimal as possible.

Never uses OnTriggerStay/OnColliderStay and you should be good.

[tropic pulsar]

Hmmm these are extra expensive?

[tender light]

That is IF your platform is PC. For mobile it might be problematic with older devices.

[tender light]

Yeah. Its pretty sub optimal in my experience. If you have a lot of them it can get rough in regards to performance. Especially if there is a lot of objects on the colliding layers.

[subtle moon]

Seems good, still getting a stable 50FPS even while torturing the physics engine. I'm targetting PC anyway!

[tender light]

Its easier to just add the object to a list OnTriggerEnter and remove it on Exit. That way you can cache whatever component you need from it. And don't have to GetComponent<> all the time

PS: there will be issues with collections being modified while enumarating over them and the list containing null values. But that's a tradeoff for performance. You can solve those with some googleing

[obsidian glade]

as an option you could consider using DOTS - the Unity dots physics and Havok physics are both (mostly) deterministic and are both boxed performant solutions which wont have you writing too much physics code, though it will mean integrating DOTS

[tender light]

Measuring FPS in editor is misleading. Measure in build if you really want true numbers.

[tropic pulsar]

I would not recommending doing anything with DOTS if you are not very comfortable programming and using Unity.

I have 10+ years exp as coder and I am struggling to get even basic stuff working in DOTS.

[subtle moon]

I know, just using that to give some indication on what's going on:D Thanks for the info about caching, solid tips. I do that as much as possible already with all my raycasts being nonAlloc etc.

[subtle moon]

Yeah, I considered it when I was starting this project, but I'm pretty sure it would be too hard for me lol

[tender light]

Dots and Havoc are both 3D only anyway no?

Not that they cant be used for the music synth project but... might lead to other issues.

[obsidian glade]

it's definitely not easy, but if you want a lot of marbles running deterministic physics in a performant way, it's probably the easiest option

but perhaps your project can make do without one of those requirements

[subtle moon]

For now at least, maybe V2 will be built using DOTS.. Who knows, maybe DOTS itself is a bit easier to use by then too hahah

[supple magnet]

I think it's like this because your spawning is using Update instead of FixedUpdate.
I would change the spawning to use FixedUpdate instead of InvokeRepeating.

[subtle moon]

Worth a shot, I'll try! The spawning interval can be changed in game, but it doesn't have to be more precise than the length of a fixed update, so that could work.

[dapper cave]

is there a performance penalty for moving a kinematic rigid body outside fixedupdate?

[sly grove]

Well Update typically runs more frequently so you'll be moving it more times

but otherwise no. You need to be aware that transforms and rigidbodies are only automatically synced right before the physics update though

[dapper cave]

that's what i thought

[livid zephyr]

Hey everyone!

I have a bunch of game objects that I want to be able to change thier colors individually when they are being started at by my camera but currently all my objects start changing colors even when they're not being stared at, can anyone provide me some tips?

I can share a video showing whats going on

[elfin tundra]

send the code you're using to check if the camera is pointing at the objects

you should be using raycasts most likely

[livid zephyr]

Yes i am using raycasts

[elfin tundra]

wait hang on

there might be a faster way

check out the OnBecameVisible and OnBecameInvisible functions

those are called when objects move on and off the camera's view

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

add those functions to your objects' scripts instead of raycasts and it will work better and probably faster too

[livid zephyr]

Hmmm

Hmmm okay i have code set up to change the color gradually because im trying to creating a scanning effect

Let me try that

[elfin tundra]

so it might look something along the lines of

class YourObject : MonoBehaviour
{
    bool cameraLooking = false;

    void Update()
    {
        if (cameraLooking)
        {
            ChangeColor();
        }
    }

    void OnBecameVisible()
    {
        cameraLooking = true;
    }

    void OnBecameInvisible()
    {
        cameraLooking = false;
    }
}

not sure if that's exactly what you're going for but that should work for continuously changing colors

[regal olive]

This actually does help! I'll also change the other physics settings.

I'll give it a try

I have a drone player and trying to set it up where it can "scan" the objects and once the camera has the scan area into view, the scan area will start gradually changing colors

i have an fps cam and a topdown cam, and the fps cam can see many zones but only want it to scan one at a time

so hopefully this can help

thank you

[elfin tundra]

awesome! hopefully it works

i think what i sent should work for that purpose

[livid zephyr]

@elfin tundra This works but i dont want the zone to turn red until the camera has the full zone in view and is close to it

@elfin tundra like this close is when I want it to start changing because at that point its scanning

[elfin tundra]

ok so you could add an additional check in the OnBecameVisible function

something like if (Vector3.Distance(transform.position, camera.position) < someValue)

[livid zephyr]

😮

of course!

Let me try that

Hi, question about Behavior-Driven Steering at the Macro Scale. I was watching https://www.youtube.com/watch?v=6BrZryMz-ac and was wondering about the direction gizmo, I read the article and realized it'd be perfect for a system I was working on and was wondering if someone had a project or some code I could see because I just can't seem to actually recreate this. My system takes lots, around 20 positions in a sorted list, to avoid and one to find and head towards and it'd be perfect to see something like this that I could reference and specialize for my own system :)

[royal zealot]

guys im pretty much disappointed

[regal olive]

How do you make it so your chracter will look a certain way in 2d and any children(gun) will go to the other side?

[royal zealot]

is really Material property block useless in improving performance in unity todays unity 2021?

[jolly token]

No it’s about marking shader prop with PerRendererData, not MPB

MPB has performance improvement ofc

[royal zealot]

well...thanks about it...i just got clear on another platform

[jolly token]

But in a sense true, since MPB does not work with SRP

Ray ray = cam.ScreenPointToRay(Input.mousePosition + recoil.deviation[recoil.heat]);

I am trying to add deviation from the crosshair for recoil. is it the right way if i add deviation values to mousePosition for a ray?

https://gdl.space/ahijojujux.cs

[split folio]

Thats fine

[regal olive]

the thing is that its not working

[jolly token]

The value you put is too small for screen space positions
And it's not good way since it will depends on screen resolution

You should add recoil to resulting ray's direction

[regal olive]

ok thanks

I'm writing my own level editing tool and as part of it I have a series of "palettes" of level components that I can drag and drop into the scene. I'm making an EditorTool for it and I have it working, except for reverting back to whatever the last tool was, eg the move tool, for further editing of the added tool. It reverts back to the tool, but I cannot use it. Furthermore, it seems to be defocussing on all windows afterwards, so if I want to edit something in the newly made objects' inspector, I must find it in the hierarchy and select it again. Is there a correct way to add and remove tools by code? I have attached how I am adding and removing it, and hope that somebody can help me resolve the issue, as I am tearing my hair out

[undone coral]

are you asking how to use nuget package / C# .net ecosystem library in Unity?

what is your objective?

[undone coral]

you're asking how to create the player's targeting reticle? or are you asking how to author the boids style movement in this video?

why are you asking about the gizmo specifically?

@visual shore i think this is the most important screen shot

[forest cosmos]

well i was trying to figure out how to use a mechanism similar to texture atlas packing. I have a set of shapes ( not regular) with determined dimensions. I need to place the shapes in a given rectangle with specified width and length. I found out that algorithm is called irregular bin packing (used to minimize waste of space between shapes). I was wondering if there some way of implementing it in unity...

[jolly token]

You can just use C# library as long as it's built for .netstandard 2.1 and not using unsupported APIs...

[undone coral]

that's cool

in principle you can implement an algorithm yourself directly in C#

it's not complicated

have you tried?

[forest cosmos]

i'm gonna try during next week

i'll update you guyzz ❤️

it's possible that i'm gonna need some help eheh

maybe i'll come back here

[undone coral]

punch something into google and get started. find out the name of the algorithm from gogole scholar then search for some tested implementations (probably written in python), and start porting once you understand what you are doing

[plush elk]

any one knows if there is a setting in unity to keep the mouse inside the game view window?
I already setup in code

 Cursor.visible=false;
            Cursor.lockState = CursorLockMode.Locked; 
             Cursor.lockState = CursorLockMode.Confined;

but my mouse allways end up leaving the game scene space if it moves out of it

[sly grove]

Try it in a build

[abstract hill]

Hi everyone, I'm looking to implement implement a feature for a project I'm working on where I am essentially recording the output of specific cameras, ones that are only rendering certain game-objects. Right now I have this code below (working fine) where I am using the camera I am interested in to render to a render Texture, and the using the AsyncGPUReadbackRequest, waiting and then saving.

AsyncGPUReadbackRequest request = AsyncGPUReadback.Request(_renderTexture, 0, TextureFormat.ARGB32, readbackRequest =>
{
  Texture2D texture = new Texture2D(_renderTexture.width, _renderTexture.height, TextureFormat.ARGB32, false, true);
  texture.LoadRawTextureData (readbackRequest.GetData<uint>());
   
  byte[] bytes = texture.EncodeToPNG();
  Destroy(texture);
             
  new Thread(() =>
  {
    if (!Directory.Exists(directory)) Directory.CreateDirectory(directory);
    File.WriteAllBytes($"{directory}/{filename}{captureFrameIndex}.png", bytes);
  }).Start();
});

The issue I am having is that the speed in which this needs to be done is near negligible, or as close as I can get it. Right now I have though where the encoding of the PNG is extremely slow, and quite noticeable lags the games. I tried moving this to within the thread, however it is apparently not possible to do this not on the main thread.

Is there a different way to encode a Texture2D to a PNG, or is there a way to call this function in a faster way?

[sly grove]

https://docs.unity3d.com/ScriptReference/ImageConversion.EncodeToPNG.html

Or maybe... https://docs.unity3d.com/ScriptReference/ScreenCapture.html

[abstract hill]

I am using the first link, but unfortunately the function is really slow, as for the second link, the problem is I need to render from a specific camera (not the one rendering the game but one in the same position, rendering only a limited amount of objects).

[plush elk]

@sly groveI got a feeling that this is more a problem of my system

@sly grovein build mode does not work

do I need to keep the code in update?

[sly grove]

What are you trying to do

[plush elk]

keeping the mouse inside the game view window

[sly grove]

DO you want the cursor visible and moving around?

Or invisible and stuck to the center of the screen

[plush elk]

invisible and stuck to the center

[sly grove]

Then all you need is:

void Start() {
  Cursor.lockMode = CursorLockMode.Locked;
}```

[plush elk]

I just tested it in start and it works

it was in awake and it didnt work

[sly grove]

you might have other code in another script setting lock mode to something different

[abstract hill]

Hiya, found the solution for this! ImageConversion can be ran on a seperate thread and works in a near identical way, only slight difference is that I needed to get the raw data before hand. Thank you for you assistance btw @sly grove

AsyncGPUReadbackRequest request = AsyncGPUReadback.Request(_renderTexture, 0, TextureFormat.ARGB32, readbackRequest =>
{
    Texture2D texture = new Texture2D(_renderTexture.width, _renderTexture.height, TextureFormat.ARGB32, false, true);
    texture.LoadRawTextureData (readbackRequest.GetData<uint>());

    byte[] rawTextureData = texture.GetRawTextureData();
    GraphicsFormat format = texture.graphicsFormat;
    uint width = (uint)texture.width;
    uint height = (uint)texture.height;
    
    Destroy(texture);
    
    new Thread(() =>
    {
        byte[] bytes = ImageConversion.EncodeArrayToPNG(rawTextureData, format, width, height);

        if (!Directory.Exists(directory)) Directory.CreateDirectory(directory);
        File.WriteAllBytes($"{directory}/{filename}{captureFrameIndex}.png", bytes);
    }).Start();
});

Hey, i just made a game and uploaded it to itch.io, my problem is that i have a build in leaderboard with playerprefs. This works fine for pc builds locally but on itch it does not really make sense since everyone can only see their own scores. Is there a way to make the leaderboard shared and somehow save the data on itch.io or some workaround that could make it work?
thanks in advance (:

hi is there a hit.textureCoord in RaycastHit2D hit??

here's my code that I wanted to convert in raycasthit2d

https://codebeautify.org/alleditor/y223baf87

[spring gorge]

i have 2 way to do my job

1. I set up a collider and use TriggerEnter
2. I use check distant on Update
   which more performance?

[jolly token]

No.. there is no 'MeshCollider2D' so it wouldn't make sense.
Well since the result would always land on a border of collider, you could lerp texcoord from vertices data if you know which line that hit.

[jolly token]

This would depends on how many physical objects on your scene and how many targets you're trying to check..

Do use the profiler if what you're doing is performance critical.

[young wraith]

so I need a meshcollider for hit.textureCoord

[jolly token]

You do

Hey,

Does anyone know how to get a OnDestroy method in Editor?
I making a editor tool, and I need to clean up some stuff if someone removes the script in the scene.

Regular OnDestroy doesn't get invoked

[flint sage]

Does ExecuteAlways not also execute ondestroy? 🤔

[devout orbit]

    private void OnDestroy()
    {
        #if UNITY_EDITOR
        LoadAddressableUtility.RemoveAddressableAsset(CastleTaskHelperGenerator.SharedPath + $"/{transform.parent.name}/" + $"{LocationKey}.prefab");
        CastleTaskHelperGenerator.RemoveTaskFromMap(transform.parent.name, LocationKey);
        #endif
    }```

Tried it like this but no luck

[flint sage]

I think it goes on the class

[devout orbit]

Ah, you are right

I thought It was possible to put it on the method

Is there anyway to access the icons that the prefabs store for use in an editor window?

I want these icons, presumably they must be a part of the prefab file somewhere

[tropic lake]

Warped Imagination on youtube has a video on how to use custom icons in editor windows

[rough sky]

nice

That looks good, but I don't think it's what I want

I want exactly the icon the project explorer uses

I don't think there is a way unfortunately, so I settled for just using the default prefab icon

I'm going to parse a shader file, then I want to know which uniform defined as a Texture2D, get the uniform's name
what is this tech called

[jolly token]

Why are you making inconsistent state by setting active state false when creating, but setting true when getting from pooled object? Result of both should be identical. Also, if it's instantiated then it shouldn't be called 'prefab'. You'd need general understanding of object pooling. #archived-code-general

It is relevant because you are using word 'prefab' wrong in your question. Implies that you are probably using object pool in a way it is not mean to be used.

[wispy lion]

How have you determined that your pool gets a "gotten" prefab? And what does "fail" to get a prefab mean? Are you getting some error?

[sly grove]

what do you mean by this?
What do you get?

YOu have to get something. is it Null? Is it an already destroyed object? Something else?

Are you ever releasing your objects back to the pool?

can you show all your code

[sly grove]

^

1. Why do a layer check in code? Just use layer based collisions
2. Is it possible you're releasing the same object more than once?

https://docs.unity3d.com/Manual/LayerBasedCollision.html

and for 2 - doing the check before what?

[upbeat path]

have you checked which object is generating the Null Ref? I count 4 possible options

you do NOT get a Null Ref is nothing is null. So stop assuming and check

and yet you still get a Null Ref. Please explain.

'and it just throws a nullreference ' !

GemObjectPool.current.gemObjectPool.Get(out GameObject pooledGemstone);

even there there are 4 chances of having a null ref, are you checking those?

I dont see it in your code

 GemObjectPool.current.gemObjectPool.Get(out GameObject pooledGemstone);
            pooledGemstone.transform.position = new Vector3(transform.position.x, transform.position.y - (diggerSO.gemSize * 0.025f), 

I'm just going to assume it all worked

so post your .Get code

I mean the code which is executed when you call .Get

pooledGemStone is an out parameter, it needs to be set in .Get

I have asked you to post the code of the .Get method, if you will not do so then there is no helping you

As I said, there is no helping you.

Stop making assumptions, you know your code is wrong yet you seem to refuse to acknowledge this

I am not sure if this is advanced-worthy, but I have a neural network that I'm visualising via a heatmap, the heatmap itself is working (for now), but the network isn't. For some reason my input nodes are never being evaluated and everything just returns 0. This is what I believe to be all relevant code.

heyy, i have created a banner ad and added the unity mediation code for see my banner but i never see this and i have not error for this too idk why
https://hatebin.com/lnvhzkyumq

[long ivy]

if that's the unedited game id you're using to start up with, it's wrong. Your use of task run is suspicious. Confirm that your methods are actually being called with logging or breakpoints

[thin mesa]

if you are getting a LoadFailedException you wouldn't know because you are catching it then promptly ignoring it. whatever tutorial you are following probably calls that AdFailedLoad method in the catch block in LoadAd()

[viscid blaze]

for the gameId it's not the real i have change it for post here my code 🙂

[viscid blaze]

i have juste copy paste this

[thin mesa]

ah, i misread the comment and saw that there's also an OnFailedLoad event being subscribed to. So then sprinkle some debug.logs in there or use breakpoints to make sure it is actually working. You also need to make sure you are calling the InitServices method somewhere since that would be done from an outside class

should I have two minus symbols? or do I need to pass "--args" first?

[viscid blaze]

i have learn this code and it's the same of my code for show and instance my ad

[long ivy]

but not for loading, and your code is calling load on a separate thread. Since the docs I see don't do that, that's what makes your code suspicious to me. You might break something. Any errors in logcat?

I have an AI traffic system that works okay. I use this culling system to move the traffic around the player and re-positions the vehicles when they move outside of the player's area.

Im using Universal renderpipeline and i want to set a texture/sprite onto my mesh. However its... just... transparent for some damn reason, no matter what properties i set. Why ?

I need to use the "Sprite-Lit-Default" shader, however with this one its just transparent, any ideas why ?

[flint sage]

Why are you using a meshrenderer with sprite shaders?

[vocal dagger]

Is there a special renderer for only sprites ?
Its because i have a 3D plane... where i wanna put a sprite onto it basically

Like imagine a 3D game where the ground is made from 2D tiles, each tile is a 3D plane... and i wanna put a 2D texture onto it

[flint sage]

Well the sprite component sets up the material and stuff for you

So it's hard to know what the sprite shaders require to render properly

But one thing is clear is that they're not meant for this

[vocal dagger]

However the sprite renderer only works on ui or am i wrong ?

[flint sage]

No that's Image

Idk if sprites work at random world space angles but again, you're abusing a shader that's not meant for this

[vocal dagger]

Oh i see, well however i cant change to much here... its a library i use which does the tiling for me basically. All i know is that since i upgraded from 2020 to 2021 its broken. It worked before and showed the tile properly

And it used the shader before the change

[flint sage]

In that case, go compare the shader and see what changed

You can download unity's shaders from their website on the download page

calling BuildPipeline.BuildPlayer(options) seems to set the build target in the editor. Is there a way to make it not set he build target or to reset the target?

[turbid tinsel]

Two minus symbols

[gray zinc]

it turns out 1 minus symbol was fine, the problem was not related to the args. i think two minus symbols is for Windows?

[turbid tinsel]

Pretty sure it's for linux as well, but hey, if it works it works! It might be more elastic in linux

Also depends how you get your args

Different ways of getting them have different results
Technically you dont need to have any minus signs, if you're doing it the most low level way

how to set up 60 fps target framerate for android?

i mean what is the procedureZ?

[woeful trout]

So, I'm a little lost

We're building a topdown with Unity for our term project

And our current task is to build some kind of diagram mapping system. The next phase is building a code skeleton, and then we move on to implementation

But honestly, I'm drawing a bit of a blank

Can someone help me get started?

[velvet rock]

What are the requirements

I probably would start with generation of it from your data source, let’s say json file. Instanciate a prefab for each node of the diagram, the connection between you could programmatically draw or find some asset that draws an arrow. Not sure what a code skeleton is, assuming a programmatically created skeleton, but the 2D hinges can work for bone structures

[turbid tinsel]

If you want to limit the framerate, you can use Application.targetFrameRate = 60 but I think it's somewhere in the project settings too

What type of coding can you do with Python within a game engine, do I need to think about creating tools?

[undone coral]

the official unity python package is editor only

[sly grove]

Within Unity? Almost none, other than creating external plugins.
There are python based game engines like PyGame

[bold berry]

Sometimes i read think like scripting that can be done with Python to create tools for engine like blender, unity, unreal whatever.

[sly grove]

Blender uses Python as a scripting engine, yes

[gray zinc]

everything in unity uses C# except for the core internals that use C++

[undone coral]

try to use cutout instead of blended for leaves #🔀┃art-asset-workflow

[undone coral]

yes, you can create tools for unity using the official unity python for editor package

that is the idea

[bold berry]

That's still Python language?

[sly grove]

It's not called "Boa Constrictor" now is it?

[bold berry]

It's just that game development in general is broad, I have seen it's to much for me so I just wanna focus on a langauge to niche more, so thought python was used for creating tools.

C++ for now way to heavy.

[undone coral]

usually when people say "tools" and "python" they mean file format conversions

and other things related to "pipeline"

@bold berry is that what you are interested in making: pipeline tools??

[bold berry]

What specifically can you present to a company, to show off you coding skill, without being to much busy with, level design or whatever.

[undone coral]

i see, are you a student?

[bold berry]

Not really.

[bold berry]

No

[undone coral]

this is a really hard question 😦

in my experience there are so few programmers with advanced knowledge of C# in Unity that it's obvious when you see one

i've seen the source code for many, many video games written in C# in unity. in my experience, code style is predictive of developer quality / personnel performance. use of advanced things like IDLs, build tools, async/await, Jobs is highly predictive but very rare. "years of experience" after "1 year" has not been predictive (so 0 versus >0 is predictive, but 2 versus 3 is not). @bold berry

[bold berry]

I just try to narrow down what projects I can work on and what technics companies wanna see, so I have better focus and motivation. My main focus is mostly game play programming.

[undone coral]

so if you were trying to work for me, whether now or at the game studio i worked at 10 years ago, i would want to see some pre-existing unity project you worked on. doesn't have to be fully authored by you, as long as it is "git blame" clear what you did. then i would look for things like

good:

• mastery of git especially using the cli exclusively, GUI / idiomatic merge tools
• comments and documentation in code
• use of access modifiers
• [SerializeField] private float m_SomeNumber
• struct versus class used sensibly
• two space indentation
• union types ([Serializable] struct NumberOrString { float number {get;set;} string text {get; set;})
• C# features like sealed, unsafe, const
• switch, enums
• using HDRP / URP, custom passes / render features, volumes, graphed / vendor materials
• reactive programming (UniRx)
• functional programming (Linq)
• async/await (+UniTask)
• Event System for UX
• Event System for 3D UX (PhysicsRaycaster3D)
• simple UI framework for screens / pre-existing one
• use of packages and focused asset store assets
• DOTween for animations
• cinemachine for camera control
• new input system
• vendor multiplayer solution (photon)
• build tooling (npm, gradle, bazel, cmake, etc.)
• IDLs (protobufs, msgpack)
• VFX Graph and Shader Graph
• networking IDLs (openapi, grpc)
• server backend background knowledge (what REST is, OIDC basics like what a token is, Authorization: Bearer xyWZ versus Authorization: [base64 encoded username: password])
• CI/CD knowledge (writing tests, building from the command line)

bad:

• stubbornly using source control GUIs (with the exception of merge tooling)
• scriptable objects with behavior in them
• built in render pipeline
• writing your own shaders for built in render pipeline
• amplify shader editor
• updateloopese void Update() { ... timer -= Time.deltaTime; if (timer < 0) { ... }}
• input based updateloopese if (Input.GetMouseButtonDown(0)) buttonThisFrameDown = true;
• writing your own tweening Vector3.Slerp(...)
• writing your own event system if (Physics.Raycast(..., out var hit)) { UserDidClick(); } especially if you already use it for UGUI but don't comprehend you can use it for 3D
• writing your own state machines
• writing your own networking new UdpClient() ...
• writing you own sprite tooling, like creating sprite clips based on how files are named
• low level networking used directly
• multiple canvases
• multiple main cameras
• multiple scenes
• "dont destroy on load"
• no access modification public float someNumber
• custom serialization ISerializationCallbackReceiver
• gratuitous generics X : MonoSingleton<X>
• gratuitous interfaces GameController : IGameController
• gratuitous coroutines / coroutines that don't yield
• flawed, plain async
• zenject / dependency injection frameworks

if you checked all the boxes in the good column and none of the boxes in the bad column, i would make you "Director of Game Programming" if that makes sense

on the other hand, the people you are talking to are not going to be experienced enough, necessarily, to know any of this

B people hire C people...

@bold berry hope that list is helpful

[gray zinc]

what's wrong with writing custom state machines?

[undone coral]

to me it just means you haven't ascended yet

you don't understand yet that it's unnecessary and a distraction

or you haven't figured out how to solve the problem better because you lack the background

but really, that's a matter of experience

someone with a lot of checkboxes in the good column will be able to pick up the language features / paradigms that obviate state machines

so they never try authoring one

[gray zinc]

huh ok

[undone coral]

of those things in the bad column i used to do, probably gratuitous generics was #1

since experience isn't really predictive after 1 year

the thing i would be looking for is, do you anticipate that there are better paradigms than timer -= Time.deltaTime

for example

there are people who have been writing C# unity code for 10 years who still do timer -= Time.deltaTime

[gray zinc]

instead of using a timer, stopwatch or a Task?

ah because your list specifically is in the context of Unity C# development, not C# as a whole

[undone coral]

instead of using a coroutine (good) or an async UniTask (better)

[gray zinc]

or a plain C# async Task?

[undone coral]

or a tween

[undone coral]

no because that means you don't know yet that plain C# async is flawed in unity

[gray zinc]

what if I want my code to work outside of unity?

what do you mean?

[undone coral]

plain c# async has glitches in unity

async void Start() for example is really problematic

[gray zinc]

Yes plain async methods are problematic

I'm saying using System.Threading.Tasks

[undone coral]

yes, the non unity c# stuff on the good list

like functional / reactive programming

[gray zinc]

Ok

[undone coral]

i would also suggest using cli tools in general - for example, using git from the command line exclusively

i can write it in order of what's most predictive (CLI use of git is probably #1, followed by code style, then functional & reactive programming)

really if you are not stubborn about using Git GUIs

being stubborn and using a Git GUI even when someone tells you not to

that's super predictive of bad

[gray zinc]

i mean if all you need to do is push and pull doing it from the app is fine imo

refusing to use the CLI git is not fine though

[undone coral]

like i said

100% cli git

i think what @bold berry is discovering is that a lot of the things he's looking for is on the "bad" list

like zenject

there will be people who want zenject, and they'll hire someone who is excited about it, and it'll be a team of B people hiring Cs

i'm not saying those opportunities don't exist, i just cannot speak to them as good

[gray zinc]

that's fair

[undone coral]

like you'd think writing your own networking is impressive and it's actually a really bad sign

it means you're choosing to do something super low ROI and pointless

for your game that no one will play

whereas functional programming you can use forever

[undone coral]

also in editor it's different than in standalone. if you're on windows and using URP / HDRP, try

mygame.exe -force-gfx-mt -force-gfx-jobs native -force-dx11

to enable all pipelinining features. QualitySettings.maxBufferedFrames should be kept on its default (which i think is 2)

[royal zealot]

whats about mobile?

someone says to uncheck "graphics jobs" on the quality setting

[bold berry]

@undone coral whats bad about ```- updateloopese void Update() { ... timer -= Time.deltaTime; if (timer < 0) { ... }}

• input based updateloopese if (Input.GetMouseButtonDown(0)) buttonThisFrameDown = true;
• writing your own tweening Vector3.Slerp(...)
• writing your own event system if (Physics.Raycast(..., out var hit)) { UserDidClick(); }```

How would you detect input?

Hi all, I was wondering if someone could explain to me why the load Task is being considered complete before it calls the debug log Debug.Log("Test: 2"). I want to process some large files from JSON to a class without needing the game to freeze, but for some reason the loadTask.IsCompleted triggers true before it actually has. Something strange as well is that Debug.Log("Test: 2") never seems to be called even after waiting for quite a while, when before hand (when the function wasn't async) the game would freeze for 10 seconds and then load it. My thoughs where that JsonUtility doesnt work with async and causes it to break out of the lamda, but I have no errors in the console.

public IEnumerator ProcessInputs()
{
    Task loadTask = LoadAsync();
    yield return new WaitUntil(() => loadTask.IsCompleted);
    
    Debug.Log("Test: 3");
    
    Task processTask = ProcessAsync();
    yield return new WaitUntil(() => processTask.IsCompleted);

    Debug.Log("Test: 6");
    
    Save();
}

private async Task LoadAsync()
{
    Debug.Log("Test: 1");

    Task loadTrackingData = Task.Run((() =>
    {
        _trackingDataContainer = (inputTrackingData == null) ? null : JsonUtility.FromJson<SessionTrajectoryDataContainer>(inputTrackingData.text);
    }));
    
    Task loadEventData = Task.Run((() =>
    {
        _eventDataContainer = (inputEventData == null) ? null : JsonUtility.FromJson<SessionEventDataContainer>(inputEventData.text);
    }));

    await loadTrackingData;
    await loadEventData;
    
    Debug.Log("Test: 2");
}

This is the debug log

[undone coral]

event system

or input system for those rare non touch games

[undone coral]

use unitask

almost none of this will do what you think it does

[abstract hill]

Is UniTask a package? And could you explain why it isn't going to work too? (Sorry I'd like to understand where I went wrong with this)

[fresh salmon]

You're mixing up async and coroutines basically

That's not going to turn out well, either do it all coroutine or all async
