I am getting all the types and their respective icons

I couldn't do much except a try catch, which was somewhat slower

also I am not a he

[novel plinth]

checking a type with magic strings were never a good thing.. just saying

[hallow cove]

I know

but it works

and there's not much of a fix to my knowledge really

reflections are the bane of my existence
why does this return an Ambiguous Match Found exception:
if (userData.methodInfo.IsStatic)

I think I asked and will probably still ask a million questions regarding them, because even though the C# documentation says something, unity will not respect it

[austere jewel]

are you sure it's not getting the method that returns the exception?

I don't see what could be ambiguous about any of the above

though I'm not sure as to the context

[hallow cove]

it's the method Debug.Log

which is static

[austere jewel]

show the stack trace

[novel plinth]

proly just missed the declaringtype flag

[hallow cove]

nevermind it seems it has fixed itself

[novel plinth]

IF it still not fixed, you can test it like this

        var someT = "".GetType();
        var methods = someT.GetMethods();
        if (methods .Length != 0)
        {
            for (int i = 0; i < methods.Length; i++)
            {
                if (methods [i].DeclaringType == someT && !methods [i].IsSpecialName)
                {
                    StringBuilder sb = new StringBuilder();
                    if (methods [i].IsStatic) { sb.Append("static "); }
                    if (methods [i].IsPublic) { sb.Append("public "); }
                    if (methods [i].IsFamily) { sb.Append("protected "); }
                    if (methods [i].IsAssembly) { sb.Append("internal "); }
                    if (methods [i].IsPrivate) { sb.Append("private "); }
                    Debug.Log(sb);
                }
            }
        }

[hallow cove]

yeah but the issue was literally methods[i].isStatic returning an exception

the bool itself was the problem

but it seems to have fixed itself now

reflections sometimes-

do that-

[austere jewel]

It really doesn't lol

[hallow cove]

for instance, just now another script which worked perfectly is giving me that exact error

yet it still works

anyways, thanks lots for the help

I ask way too many questions here, but what can you do when the code isn't doing what the documentation says it's supposed to do 💀

[vestal condor]

is there no way to draw lines on canvas in a way like linerenderer?

pass in a bunch of vertices and let it draw

or do I really have to use GL for this

[austere jewel]

Image has a OnPopulateMesh function you can use to construct your own mesh using the VertexHelper object is passes in, and you can do whatever you want

It's quite low level though so it's not great to work with.

In the future you can use UIToolkit, where they have a fantastic mesh drawing API

[drifting galleon]

using a mesh for it is ok, but i highly recommend using a shader to draw a line with signed distance fields. i've just recently wrote such an exact shader

[brave talon]

Can someone help me make a toon shader in URP shadergraph?

[drifting galleon]

if you could post the code in whole, i'd be happy to look over it and refine it, because as i understand right now, there's just lots in there that shouldn't need to be.
only if you want of course

[hallow cove]

It's actually pretty clean

I have special classes to serialize Method, Field and Property Infos

Some methods to create nodes based on if you select a class, method etc.

The architecture is clean, but the code not so much actually

I'll post it once I finish the system and refine it myself for some last moment tweaks before slapping a "Finished" seal on it

[violet wolf]

#archived-shaders

[grave bear]

trying to use mono.cecil to generate code. Im using the ILPostProcessor and it will sometime crash right after compile. Any tips?

personally wish it would crash every time... that way I would know it's "fixed" when it stops crashing

[drifting galleon]

that could have many different sources of problem. maybe dump the generated code to a file so you can inspect it yourself.
not sure if you know that already, but you can now also use .net native source generators to generate code and that is in most cases a better solution than cecil

[violet wolf]

I've not used cecil for anything unfortunately, what do the editor logs show?

I'd say they would be the first place to check

Hopefully it is a unity problem and not some obscure cecil issue

[grave bear]

It crashes, straight to desktop. The crash log screen says it couldn't get a stack trace, and actual log file is vague on the source of the issue.

[grave bear]

I know .net has a source generator, but since Unity uses Mono.Cecil I went with that

[grave bear]

I figured there were some internal difference in the mono runtime that require its own source generator since Unity is backed by mono. Is it possible any conflicts could arise using the .net source generator with Mono?

[sage radish]

You should be aware that ILPostProcessors are executed in parallel in separate .NET Core processes, and don't have access to Unity's runtime. It might crash if you try to access something you shouldn't.

[grave bear]

Yeah good point. Going to double check and make sure it's all thread-safe

[drifting galleon]

unity uses source generators now

[drifting galleon]

no

[grave bear]

Curious, since when? Also, I looked into .net source generators and it looks a lot easier. Instead of Instructions, it's literally just strings.

Granted you have to jump through a few hoops, but that's the gist

[drifting galleon]

i'm not sure if unity already doesn't use cecil at all, but i know that a lot of recent cecil work, like in the entity package got immediately migrated to source generators

[grave bear]

The dll still exists yes, but if it's used is beyond me. Likely will stay there because some projects directly reference them instead of a package or something

[drifting galleon]

they build on the roslyn api, which takes a a bit of time to get into, but is extremely powerful and good when you get the hang of it

[grave bear]

I think one major factor in switching is the fact the code generated can be previewed in Visual Studio

Which I think is really helpful

[drifting galleon]

and it's normal readable c# code

[grave bear]

Yes! that too

making errors less, and ease-of-use 1000x easier

[drifting galleon]

also, it undergoes syntax parsing and therefore makes it relatively error resilliant unlike cecil

[grave bear]

very nice. One question I have tho, is the Generate attribute required? Im not 100% sure how execution is handled. Im hoping I can just cut out all my cecil from my current ILPostProcessorWeaver class and replace it with .net

[drifting galleon]

first, what unity version are you working with?

[grave bear]

2021.3.6f1

LTS

[drifting galleon]

ok, so unfortunately, you cannot yet use IncrementalGenerators which would be the recommended ones, because 2021 doesn't have a compatible roslyn version. so you have to use the SourceGenerators v1.
but that's not a huge issue. migration to incremental generators later on is easy.
and to answer your question: source generators can take input from anywhere or none at all.
you can simply output some generated code always, have it only generate code when it encounters specific syntax nodes (e.g. attributes), or take any other arbitrary file as input (e.g. text file) and generate code based on that

[grave bear]

What version do I need for IncrementalGenerators ?

[drifting galleon]

i've not tested myself, but from the forum i've read that 2022 has an updated roslyn version again and people said that therefore incremental generators should be working

[grave bear]

good news! I have 2022.2b1 installed so I'll give it a test run. But for now, ill do like you said using SourceGenerators v1, if I can find it

[drifting galleon]

which means you will need to use an api version compatible with the older roslyn of 2021. else they will not work

[grave bear]

do you have any sources I can follow? I only have this one to go off of right now: https://docs.microsoft.com/en-us/dotnet/csharp/roslyn-sdk/source-generators-overview

[drifting galleon]

it's not changed much, especially not the v1 ones (which these docs use) on the bottom you can find a link to samples and a cookbook

[sage radish]

Unity.Entities is still using IL Post Processing according to this
https://github.com/needle-mirror/com.unity.entities/tree/master/Unity.Entities.CodeGen

Not everything that can be done with IL processing can be done with source generators. You can't modify existing source code with generators.

[drifting galleon]

yes, but that's also something you should not do

and actually, you could do it with source generators

or rather the roslyn api

[sage radish]

Of course you shouldn't be modifying the user's source code. But IL processing doesn't do that.

[grave bear]

Yeah the example on the docs shows a virtual method getting replaced with actual code

[drifting galleon]

ok, maybe they still use it for a tiny amount. but most has been reworked into source generators which is great. and maybe the rest at some point too

[sage radish]

That still requires the user to define their class as partial

[drifting galleon]

it's not so much replacement as it is addition

[subtle shell]

Hello guys !
OnPreCull is not running in URP ( i think its because of the URP )

[grave bear]

Isn't ILPostProcess just an entry point to modify the current compiled assembly?

[drifting galleon]

any unity messages about camera stages do not get called in any SRP

[sage radish]

Yes, and in a performant way by running them in parallel with assembly compilation

[subtle shell]

so how to do that ?

i really need this event

[drifting galleon]

you have to write a custom render feature

[subtle shell]

can i use the same code ?

[drifting galleon]

look at the docs

[drifting galleon]

no

[subtle shell]

oof

[drifting galleon]

they work fundamentally different

[drifting galleon]

black box magic
== bad imo

and microsoft thought so too

or like, not 'bad' but rather a last resort

[subtle shell]

tysm

[grave bear]

https://www.nuget.org/packages/Microsoft.CodeAnalysis.CSharp/4.3.0-2.final#versions-body-tab so I uhh need literally v1?

[drifting galleon]

just a sec. i'll check which version my project uses

[grave bear]

im hoping I can use something newer, because 6+ years is a loooong time in terms of updates/features

[drifting galleon]

<PackageReference Include="Microsoft.CodeAnalysis.CSharp.Workspaces" Version="3.8.0" PrivateAssets="all" />
    <PackageReference Include="Microsoft.CodeAnalysis.Analyzers" Version="3.3.2" PrivateAssets="all" />

these work

[grave bear]

awesome thank you

[drifting galleon]

i'm not talking about roslyn api v1. 6+ years ago source generators didn't even exist.
i am talking about SourceGenerator base class (referred to as source generators v1 in docs) and IncrementalGenerator base class (referred to as v2 in docs)

[subtle shell]

cant i just use this ? :

using UnityEngine;
using UnityEngine.Rendering;

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        RenderPipelineManager.beginCameraRendering += OnBeginCameraRendering;
    }

    void OnBeginCameraRendering(ScriptableRenderContext context, Camera camera)
    {
        // Put the code that you want to execute before the camera renders here
        // If you are using URP or HDRP, Unity calls this method automatically
        // If you are writing a custom SRP, you must call RenderPipeline.BeginCameraRendering
    }

    void OnDestroy()
    {
        RenderPipelineManager.beginCameraRendering -= OnBeginCameraRendering;
    }
}

and do the same thing ?

[drifting galleon]

no

[subtle shell]

why ? 😦

[drifting galleon]

because they work FUNDAMENTALLY different

[subtle shell]

in the docs it said they have similar functionality

[grave bear]

oh ok lmao that makes more sense. I was confused on the v1 thing thinking unity was behind on updates 😂

[drifting galleon]

sorry, looked like legacy code at a glance so didn't read it at first.
i mean....maybe? i've not seen this anywhere. if yes, then that's definitely something newer than last time i checked

[drifting galleon]

i mean....unity is....but not that much XD

[grave bear]

yeah haha

[subtle shell]

oh tysm

[grave bear]

Thats for the inc generator

now to see which ver of unity 2021/22 supports...

[drifting galleon]

you should also read this: https://stevetalkscode.co.uk/debug-source-generators-with-vs2019-1610
to be able to debug your source generators efficiently. (because you can look at any docs or anywhere on the internet and there's not a single thing written about what debug possibilities there are. [because at first there weren't any and i guess they didn't bother to update the docs when they improved on that])

@grave bear

[grave bear]

Wow that will be helpful, thank you. Also, for context if anyone else is curious I found this: https://docs.unity3d.com/Manual/roslyn-analyzers.html

[vivid night]

Hello, I am having a bit of trouble with Sin and Cos not outputting correctly. So I have code where an object goes towards its parent and switches its state to its Idle state, where it is to then orbit around it parent, but when it enters Idle, it jumps a bit to a new position. So when I checked it out, using the calculated angle of 180, I found that both the Sin/Cos of 180 equal a decimal, which is not what my calculator says.

angle = Vector3.Angle(animator.transform.parent.position, animator.transform.position);
        Debug.Log("Initial angle: " + angle);
        Debug.Log("Sin " + Mathf.Sin(angle));
        Debug.Log("Cos " + Mathf.Cos(angle)); //angle = 180

Results:

Initial angle: 180
Sin -0.8011526
Cos -0.5984601

Ideally, my goal is to make it so my object would start orbiting from where it is in relation to its parent rather than having to jump like it does.

[drifting galleon]

they work with radians, not degrees

i think

[valid token]

I want to download a plugin in code from a URL, unfortunately it creates the jar incorrectly and is only recognized as a ZIP by the compiler. I download the jar with Commons IO

FileUtils.copyURLToFile(new URL(fromUrl), new File(localFileName),10000, 10000); 

Does anyone have an idea how I could integrate the plugin.yml, or what I could change from scratch?

[drifting galleon]

this question doesn't seem to be related to unity

[vivid night]

Thanks, that seems to have given me the direction I needed

[grave bear]

@drifting galleon Last question (hopefully) is regarding the creation of the the actual code. Can it overwrite dlls/modify existing code? from the looks of it you can only generate new code and not overwrite existing code.

[austere jewel]

There is no job or collab posting here. See #📖┃code-of-conduct

[acoustic tinsel]

sorry

[drifting galleon]

Primary purpose is addition not deletion

[grave bear]

Ok understandable.

[drifting galleon]

That's not a limitation. It's a design choice

[grave bear]

It may or may not be harder to design the codegen around addition, not deletion haha

[sage radish]

Source generators don't solve the same problems as IL processing. They have different uses.

[grave bear]

likely harder because now I have to make an extension class that calls the relevant code collected from reflection

[drifting galleon]

They share a huge part of problems that are solvable either way

[grave bear]

Im not "deleting" anything but I am modifying the class Im interested in, which just amounts to adding a few methods and some attributes

[drifting galleon]

Most reflection stuff can be substituted by source generators

[grave bear]

yes, but at runtime I have to use reflection. this is for an auto-serializer

[drifting galleon]

That's easily doable. Just make it partial

[grave bear]

yes, that is what I think I will eventually do

[rugged radish]

hello guys
have anyone tried scheduling a unity job from inside an async task ? Is that allowed ?

[drifting galleon]

Probably

[rugged radish]

while (!job.IsCompleted) await Task.Delay(delayMs);

if delay is very small it throws an exception when I try to read from the job result after that line
but otherwise It looks like it's working fine

what am I missing here ?

the job is quite fast. other, slower jobs have the same check and don't have any issues

[drifting galleon]

Job.iscompleted will never be true until you call .complete() on the job

[rugged radish]

it would hang indefinitely in that case and wouldn't produce any results

and I can see that it produces the mesh just fine

I thought that Complete() forces the controlling thread to wait on the job

[drifting galleon]

It does. But a job does not get executed before .complete() is called

[rugged radish]

I'm getting all the results from all the jobs, and I don't use Complete() on either of them
I mean, I'll double check again, but seems like Schedule is enough to start a job, pretty sure it says the same in the docs

[drifting galleon]

No. You may be calling ExecuteScheduledJobs or ScheduleQueuedJobs somewhere (I'm don't know the correct name of the method right now)

[rugged radish]

I can tell it's working just by how the game runs now
moved the mesh-gen routines into the job system to avoid framerate drops on chunk transitions
and those transitions are finally silky smooth

[rugged radish]

I don't, because this is the only place where I use the job system

[agile yoke]

Complete is not necessary for a job to run, but it is necessary to e.g. be able to access native collections you passed to the job again without the safety system complaining

[drifting galleon]

I have no knowledge of your code. But I know that jobs don't run without .complete() or the ExecuteSchedulwdJobs()

[drifting galleon]

We had a long discussion on jobs in #archived-dots months ago and we all came to the conclusion that jobs need 1 of the 2 criteria or they won't be run at all

[agile yoke]

Well, I don't know how you came to that conclusion, but it's easy to show that it's not true ^^'

[drifting galleon]

We have waited seconds on the job completion of a simple job and it would never complete.
And it even makes sense how it works

[agile yoke]

public class JobScheduleTest : MonoBehaviour {
  [ContextMenu("Schedule")]
  public void Schedule() {
    new Job().Schedule();
  }

  private struct Job : IJob {
    public void Execute() {
      Debug.Log("The job ran!");
    }
  }
}

I can throw this on an empty object in an otherwise empty scene, run schedule, and the log will print after a moment.

It's entirely possible that there's no guarantee that a job will run absent any Complete or ScheduleBatchedJobs calls, but it's definitely not true that they never will.

[drifting galleon]

Put it into Start() instead and try

[agile yoke]

works too

[drifting galleon]

I can't check it currently but then they have reworked the job system because this is definitely how it used to work

[agile yoke]

Nevertheless, the pattern to use jobs is:

• Schedule them as early as possible, and either
• Complete them when you need their result; or
• call ScheduleBatchedJobs if you never really need access to their result and just want to make sure they execute.

[rugged radish]

from what I'm seeing in the docs and in my code Complete() ensures that you can safely access the results
but you don't need it for job to start running
and you can even get the results if you're lucky (which seems to have correlation with the frequency of your polling)

that being said, seems like Complete() is the correct method to wait for the result, I'll try using that instead of a while(!IsCompeted) and see it causes main thread to freeze

[drifting galleon]

And use SBJ extremely sparsely

[agile yoke]

agreed, Complete is preferable I think

[austere jewel]

Unity's subsystems will call JobHandle.ScheduleBatchedJobs on their own in the background so the above test is not a good measure of whether jobs will start without it

[drifting galleon]

Interesting. That must be a new addition of a recent version then

[agile yoke]

I guess that depends on what you mean "without it". "Unity does the equivalent at appropriate times automatically in a normal project" still means "your job will run without you calling it"

[austere jewel]

I think the SheduleBatchedJobs docs is pretty clear about it being the thing that actually kicks it off:

By default jobs are only put on a local queue when using Job Schedule functions, this actually makes them available to the worker threads to execute them.

The job system intentionally delays job execution until you call ScheduleBatchedJobs manually because the cost of actually waking up worker threads can be expensive. Thus a good default is to delay the actual kick until a few jobs have been scheduled. Generally if you are scheduling a bunch of jobs in a loop, wait with kicking the jobs until the end of the loop. If you do significant amounts of work on the main thread between scheduling jobs, then it can make sense to ScheduleBatchedJobs between each job.

[drifting galleon]

And when does the subsystem call SBJ?

[austere jewel]

No idea, there are many packages and other shit that use jobs

Any one of them in a project could do it at whatever point they run

[rugged radish]

so, Complete() does freeze the main thread
but

jobHandle.Complete()```
doesn't, and also doesn't cause the safety exception

[drifting galleon]

So yeah, the jobs won't run. They may run if you use other packages.

[rugged radish]

yeah, I'll put the ScheduleBatchedJobs at the end of the loop

[agile yoke]

huh, those docs are surprisingly clear/specific, especially around "you" being supposed to call it at appropriate times. The "C# Job System" docs make it sound a lot more like "call it if you really need to, be careful with it performance-wise, Complete is better"... but that advice really only makes sense if you're going to need the job results immediately, not e.g. next frame, if there are no implicit schedule calls :/

[rugged radish]

thanks for the clearing things out guys, really great help ❤️

[drifting galleon]

You can just call .complete() the next frame as recommended.

It just doesn't work over multiple frames

[agile yoke]

Only when relying on an implicit SBJ call somewhere. If I schedule a job and complete it next frame, I want it to actually run in the background while the main thread is progressing through the frame (assuming worker thread availability), not only start when I call Complete next frame.

So I definitely would've expected Unity to insert some amount of automatic SBJ at appropriate times, even if it's just at frame boundaries.

[drifting galleon]

When you .complete on the very start of the frame it has all the time

[austere jewel]

I have jobs which run until they are done, and then I call Complete to get the data

Just use SBJ as appropriate, sometimes the earlier you start the jobs the better for your setup

[drifting galleon]

That wouldn't be great for performance

[drifting galleon]

For most jobs a simple .complete without an sbj call is enough in my experience, but you are correct for more heavy jobs

[agile yoke]

what "all the time" are you meaning? If it only starts when I call Complete, the main thread will then proceed to be blocked and do nothing until the job has finished.

[agile yoke]

Apparently so, definitely learned something new here regarding the scheduling behaviour. Thanks for weighing in!

[drifting galleon]

It just passed a frame to the GPU, now you have a quick sync point and then you can move on to the next frame. That is the recommended approach in the docs

And presentations too iirc

[undone coral]

i review the hdrp source to get a grip on jobs

they are really complicated

i wish someone would just take the language and interface of Tasks

[drifting galleon]

they aren't. you just need to get into them

[undone coral]

and just... rename this stuff

yeah i mean you're right they're not complicated

maybe the word i'm looking for is arcane

[drifting galleon]

not even that

[undone coral]

hmm

well help me out

[drifting galleon]

what do you need help with

[undone coral]

nevermind no i don't have an urgent issue wiht jobs at the moment

i haven't really gotten into it yet. i use a native plugin that unity communicates with via a plugin rendering event from the render event. i have an obstacle where that causes the render thread to wait until the native method returns, which is expected but undesired - it has no side effects on rendering

and i've been exploring if it is possibly to wrap that somehow in a job, so that i can communicate to the render thread that there are no dependencies on the result

i don't think i need it to actually run in the background

it is work done to the render texture a camera is rendering to. an expert recommended that i get the unity source and work with the finished frame buffer directly, or potentially using a custom pass

[daring pelican]

Some weird issue... So my code recompilation in the editor either takes 1 second or 90 seconds, seems very random. That's in a clean project. Anyone had anything like that? It just started happenning out of the blue

[left mauve]

Does it reimport stuff, when it takes 90 secs?

[white seal]

Does anyone know if code inside a #UNITY_EDITOR preprocessor directive will run when unity is in --batchmode

sorry to be more specific

also with the nographics flag

[sly grove]

Should - it's the batch mode editor, right?

or batch mode player?

( i don't remember if the latter even exists)

[undone coral]

you mean

in the editor?

yes

batchmode does two things - honestly i don't know why they haven't written this

it turns off the render loop, and a side effect of that is the render loop has a dependency on the platform's presentation approach, which on windows is... a window, and it will not create that window

that's it

[white seal]

Interesting I thought that was what the -nographics flag was for

[undone coral]

there is a player loop subsystem called RenderLoop or WillPresentFrame or whatever

-nographics initializes a graphics device called a "NullDevice"

that's it, that's all it does

[white seal]

ah got yeah

[undone coral]

the net effect is that command buffers, i.e. requests to render, will be no-ops

[white seal]

sweet

thanks so much

[undone coral]

they should document this stuff!!

[white seal]

Having a strange issue where an asset is causing issues with my unit tests due to a welcome window appearing on first startup

[undone coral]

that is package specific

[white seal]

yup

[undone coral]

batchmode does NOT prevent that

you will see in various unity code

checking if it's in batchmode

[white seal]

looks like lol

[undone coral]

Find Usages on batchmode

[white seal]

yup took the words right out of my mouth

[undone coral]

input system for example suppresses exactly such a window

onyl if it's in batchmode

[white seal]

Application.isBatchMode looks like this is what i'm looking for

[undone coral]

that's what you'll use to patch the pckage yes

[white seal]

sweet

thanks so much for the help

really appreciate it!

[undone coral]

i tweaked my answer to be more accurate @white seal

is there a pre-existing method that copies PointerEventData ?

why is pointer event data so ill thought out 😦

why couldn'/t they just copy the DOM model verbatim

why did they copy the DOM model like they were a non english speaking external contractor team under a punishing and illogical deadline that knew it was not going to get hired to do anything else again but was in denial?

[left mauve]

I hope its okay to ask this here: We are having problems with the Quest2 (not in Editor) that we suddenly get what seems to be random crashes on mutliple devices...
From the tombstone i get:
backtrace: /apex/com.android.runtime/lib64/bionic/libc.so (je_malloc_tsd_boot0+496)
Is the Unity Version 2022.1.9f1 still so buggy that we have to go back to 2020? We have upgraded because of the XR Interactions and URP stuff.
Does someone else have problems with the 2022 versions?

[undone coral]

if you need to use 2022 you should report bugs, but i know that's useless because it will literally take them months to get back to you

you should use whatever version facebook tells you to use

to best develop for the quest

[left mauve]

Well we are not sure if it is us or the engine 😄

[undone coral]

i don't think it's you

[left mauve]

Okay i will check what facebook thinks is good.

[undone coral]

you should use 2020.3.18f1

@left mauve that is the version facebook uses internally

i think the latest i see is 2020.3.22f1

[left mauve]

And i cannot report a bug anyway as the application is rather big and we are surely not sharing any of that with Unity. Apart from the fact i am also not their QA-Guy.

okay, thanks for the Info

[hot sand]

whenevr i try to make an avatar for vrchat it says "FileNotFoundException: C:/Users/COHAD~1/AppData/Local/Temp/DefaultCompany/My projectihih/prefab-id-v1_avtr_30f61086-4bdb-4dfa-b77e-cf1d4801c7d3_1548093427.prefab.unity3d does not exist

[left mauve]

Well, first thing is - does the file really exist?

(path and file in this case)

I see my stuff normally in the AppData/LocalLow Folders

[daring pelican]

nope, it kinda looks the same

[left mauve]

That does sound a bit strange... i never experienced that. When i had long times like that it was doing something with the MipMaps... but that was also only like 1 in 50 times that it took very long.

[hot sand]

I searched and it’s not there and idk how to get it back

[wintry wind]

Hi everyone, I’m building a spaceship game, where the camera is in the cockpit. I want the camera to move with the movement of the ships (example: lean back when accelerating). Anyone knows how to do this? I’ve googled this hard but can’t find anything (wrong term maybe)

[regal olive]

rotate the head when accelerating

using lerp

for smoothnes

[fast pagoda]

have your camera inside a parent, you move your parent for obvious stuff (like mouse movement or stuff) and move the camera itself for small "animations" like headbob and what you said
for acceleration i would also use camerafov animation for more immersive effect

[wintry wind]

I tried using some lerps and move the head on acceleration but it wasn’t very natural

[regal olive]

Do what VisionElf recommended then, sounds like it will work

[inland delta]

i would use a remap function based on the spaceship velocity given 0f and its maximum velocity and lean back based on that

but idk how it would feel

public static class Helpers
{
    public static float Map(float value, float inputStart, float inputStop, float outputStart, float outputStop)
    {
        return outputStart + (outputStop - outputStart) * ((value - inputStart) / (inputStop - inputStart));
    }
}

then something like

float leanAmount;

void Update()
{
  leanAmount = Map(rigidbody.velocity.magnitude, 0f, spaceShipMaxVelocity, 0f, 1f);

  // do the lean
}

[wintry wind]

Thanks, will try these tips

[wanton bronze]

Is IL2CPP a good option for “rewriting” C code into Unity

[sly grove]

No? it doesn't do anything of the sort

[wanton bronze]

What does it do

[sly grove]

It turns your C# code into C++

[wanton bronze]

Oh

[hollow garden]

leanAmount = rigidbody.velocity.magnitude / spaceShipMaxVelocity;

[regal olive]

Oh wtf that’s possible

[sly grove]

not only is it possible it's the default way of building a unity game nowadays

[regal olive]

Damn alright lol

[drifting galleon]

'default way' is pretty hard to say. there's still plenty that use mono and the now updated mono version is a lot closer to il2cpp performance as well.
i personally can't wait to be able to build to native .net

[sly grove]

When I say "default" I mean if you don't go into settings to change it, you're getting IL2CPP

for most target platforms

[drifting galleon]

strange. when i create a new project for default windows, mono is still the default one selected

[small latch]

Same here (I have to manually swap to IL2CPP)

[undone coral]

is there a way to get stacktraces in mono windows release builds?

with line numbers*

[grave bear]

Sorry to bother you again, but for whatever reason I'm not able to add the DLLs to my project without some assemblies unable to be resolved:

Assembly 'Assets/UnityStateNetworking/Runtime/Plugins/microsoft.codeanalysis.csharp.workspaces/Microsoft.CodeAnalysis.CSharp.Workspaces.dll' will not be loaded due to errors:
Unable to resolve reference 'Microsoft.CodeAnalysis.Workspaces'. Is the assembly missing or incompatible with the current platform?
Reference validation can be disabled in the Plugin Inspector.
...

I looked at the unity docs for source generators, but it seems kinda pointless if the source generator is just generating a class from a normal cs project, and then compiling it for unity to utilize like a normal plugin.

maybe im missing something?

[drifting galleon]

Its not pointless.
Make sure to look at the unity docs for Roslyn analyzers. You have to disable any platform inclusion inside unity and add the RoslynAnalyzer label to the dll

[daring pelican]

it turned out it was either SteelSeries or Razer software that was slowing it down

[grave bear]

Yeah I got it to work following the unity docs exactly however, maybe I'm not understanding exactly what is going on here. From the looks of it, the source generator in the unity docs example creates source code that isn't dynamic (ie, cant use reflection to get attributes to create extension classes/wrappers/etc)

wait

This is based off of the assumption that the generator is compiled outside of unity. I think I need to assign the same process described in the unity docs to the nuget packages

hold on

[drifting galleon]

The source generator is always compiled outside of unity

You can't write it 'inside' unity

[grave bear]

oh lmao I understand now

lmao now I need to make a tool that makes it more IL-like haha

[drifting galleon]

?

[grave bear]

well, it depends if Visual Studio allows me to debug the generated code without having to compile every time haha.

It would basically be just a simple helper class that does string building like AddUsingNamespace(nameof(MyNamespace)); etc

after adding a namespace, you can do: AddClassDefinition ("SomeClassName", ClassFlag.Static | ClassFlag.Public);

eventually, you will call a method that compacts it all into a single string for the Source Generator to work with

[drifting galleon]

I have no idea what you're trying to do anymore

[grave bear]

String builder that is specific to making it easier when writing Source Generator strings

very similar to how cecil works, but way easier to interpret what everything does

[drifting galleon]

Ah. So thats not code you will generate, but code of the generator itself

[grave bear]

yes exactly

sorry I should of made that a bit more clear lol

off to testing haha

[minor cloud]

I'm not sure ifthis is relevant to you, but you should know if you're attempting to use anything to do with IL Emitting or any dynamic stuff, IL2CPP will not support it as far as I'm aware, but it'd be fine for editor stuff

[grave bear]

Source generators are "editor-only" so it doesn't matter

[minor cloud]

Fair enough

[drifting galleon]

Source generators don't emit il

[grave bear]

Also, just because the source generator isn't directly tied to the unity project, doesnt mean you can bypass what your unity project is limited to (example: C# v9 API in a C# v8 project cannot be "forced" by using a source generator)

[minor cloud]

I'm aware of this, However whenever I've seen people mention dynamic code and or reflection IL Emitting often comes into play

[minor cloud]

As for this I'm honestly struggling to make the connection, it's a bit late lmfao

[grave bear]

I think how .net source generators work is by creating an actual source .cs file the compiler will read and include in the compilation.

[grave bear]

I edited it for clarity. But basically, you can't write code in the source generator using Python syntax and expect the compiler to just magically understand wtf you're doing lmao. Same with forcing newer syntax on a project that is using an older version of the language syntax.

[minor cloud]

I'm not entirely sure to be honest, haven't needed to dive into it that deep, Using CodeDom here and there to generate scripts is enough of a nightmare lmfao and ah yeah I know that, I ain't that new

Just was trying to point out that IL2CPP does have those limitations, I've seen people struggle with it before is all

[grave bear]

Noted

[knotty silo]

is there a way to script a trigger to set an item into the inventory slot position?

like when I press a button it can set an item into the inventory slot

[grave bear]

You can listen for a button event and assign it contextually based off of some parameters (like your next empty slot, if space is available, etc)

each button would have a script that keeps track of its inventory index

have an inventory script that holds all your inventory items and inventory buttons

so when you click on a button, the item will be added to that slot (or dropped, swapped, removed, inspected... lots of options) and assigned to the slot in the inventory script's list/array

Example:

InventoryScript
    |-- InventorySlotScript 0
    |-- InventorySlotScript 1
    |-- InventorySlotScript 2
    |-- InventorySlotScript 3

Clicking on one of those InventorySlotScripts which is also a button, will tell the InventoryScript to move it to that index. What I do is use a GridLayoutGroup and instantiate a InventorySlot prefab that has a InventorySlotBehaviour script attached so I dont have to do it all manually.

[knotty silo]

thank you for the advice I will try to work on that direction

[compact ingot]

at a certain point (of proficiency) it becomes impossible to make any more tutorials/courses and you are expected to teach yourself "the rest" (this is where a CS degree comes in handy), the most complete resource is MSDN or one of the respected C# books.

[grave bear]

The beginner courses are all you need, really. After that you need to do research on your own to determine the right course of action during a projects development. Learning the language is the easy part. You get to a point where you want new or improved language features. The hard part is figuring out how to construct your project, the logic flow, what you can and cannot do (don't be surprised if you have to scrap an entire project because of one small detail).

[grave bear]

Looking for an easier way to write logs to console. Any ideas? Right now I just create a txt file and write to that and then log the info into the unity debug console

[tender light]

(don't be surprised if you have to scrap an entire project because of one small detail)
Cmon man. Don't scare people with that.
a) its not true
b) even if it were you are just adding to their paralysis and indecisiveness.

[compact ingot]

what kind of logs?

[tender light]

So you are writing to your own separate file and then after you exit play mode you dump that into the editor?
I think thats a bit backwards if I understand it correctly.
What about Application.logMessageRecieved delegate? Why not use that and write to the log file after writing to console instead?

[grave bear]

just, simple message logs from a source generator

[compact ingot]

why can't you use Debug.Log?

[grave bear]

usage of the UnityEngine api isn't permitted

[compact ingot]

You can just expose a ILogger from the library and pipe that into Debug.Log

[grave bear]

Well see that's the thing, I don't actually have access to anything related to my Source Generator

because you literally cant

[compact ingot]

and the source generator does not expose its logger and just dumps it to console?

thats a terrible library

[grave bear]

...

no

[compact ingot]

maybe explain again what you want to achieve

[grave bear]

The source generator in question is a .net library that is not compatible with the current Unity roslyn compiler

so what I have to do is compile it in a standard library project that targets the netstandard 2.0 runtime

What I'm trying to do is make it easier to log to the Unity console. So far the only solution was to create a text file every time the source generator runs after compilation

Specifically, I want exception info

[compact ingot]

if you compile it to standard2.0 why can't you use it from unity directly?

[grave bear]

I could do some string magic and structure my file to make it look like it has exception info

[grave bear]

Because that's the resulting target, not the project environment

Unity doesnt actually support compiling source generators yet

their docs specifically specify to make a seperate project outside of unity to work

[compact ingot]

what do you actually mean by "source generator"? you can generate code in a unity project just fine, have unity import those files and use them on the next import.

do you want to compile a DLL from a unity project?

[grave bear]

https://docs.microsoft.com/en-us/dotnet/csharp/roslyn-sdk/source-generators-overview

In my use case, it's to resolve type-convergence

[compact ingot]

that is compile time source generation

you need to specify that to avoid confusion

[grave bear]

I thought "Source Generator" was obvious enough

[compact ingot]

that could mean anything, its a concept not a tech

anyway, can't help with roslyn source generators

[grave bear]

np, think im just going to stick with the file logging anyways

[grave bear]

a) It absolutely is true. Entire projects can get scraped if the designers overlook an aspect of their core project, that was my point. When I was still a beginner lots of projects were scrapped because I realized the scope of the project would be too much for me to handle, required complex changes to resolve some prototype design flaws, only looked at steps 1, 2, 3 and no further, and many other similar reasons.

b) If they lack critical thinking skills to evaluate the scope of learning a subject, that's on them. Programming/CS isn't something that has a small skill set that you can practice over-and-over again and get good at it in just a few short months. Every time you work on a project I guarantee you learn something new, because every project will have some sort of different challenge you need to overcome that may or may not be possible, but that can only be determined by knowing how to overcome design challenges.

[drifting galleon]

Sorry to respond this late but I was sleeping.
Ive already sent you a source that tells you how to activate debugging previously.
A source generator runs inside Roslyn, not unity, so even when unity eventually supports the better workflow you will never be able to use any unity specific apis like debug.log to 'debug' your source generator.
The file approach was the first thing I worked with as well, but it's just pain. What you want is read the source I've already linked you.
If there ever comes a point where you require unity specific types to test your source generator, the way to do it is to write a mockup of those in an extra file and use these 'fake' versions to test your source generator.

[drifting galleon]

I think it is reasonable to make the link to Roslyn source generators when someone talks about source generators in .net nowadays.

[drifting galleon]

@grave bear helped?

[grave bear]

Yeah the debugger is nice. I like being able to preview it. Buuut... I was hoping to get some sort of feedback during compilation. Its wacky tho, sometimes a log file will be created, sometimes it wont. Im not going to worry too much about it right now, just glad things are working better

[drifting galleon]

You can output the generated file as a debug option

[grave bear]

In VS or unity?

wait

[drifting galleon]

Whenever it generates any file

[grave bear]

huh, didn't know you could do that

[drifting galleon]

I personally don't use it often but it's possible

[round pawn]

I spent hours trying to troubleshoot this yesterday but to no end. The issue is that the velocity vector rotates with the first person player controller, so I can move forward, release the forward key and turn 180, and the player will still be moving forward, as if the velocity was rotated as well. I tried a number of different things, from removing the relation to the input vector while it's magnitude is close to 0, I tried Lerp and adding an opposing force instead of writing to velocity. This issue is making no sense to me, as I cannot find the root of a problem that doesn't look like it should exist.

https://pastebin.com/qXK6X4iF

Move() Line 134, called on lines 79 and 90

Thanks in advance!

Additional info:
It's the only script in the project
Rigidbody and capsule collider are the only other components on the player object
Mass = 1
Drag = 0

[undone coral]

what's your objective?

make a first person parkour game?

this is a very hard thing to do in a general way

because in the real world, you can't do general parkour - you obviously can't just run on a vertical wall forever like you do in video games

but it seems like that is your plan here, to let you run infinitely on any wall

removing gravity isn't going to achieve that

there are real life creatures that can do that, like spiders and salamanders and whatever. the problem is they can also walk on ceilings.

i would separate the problems of locomotion and the camera

or do not do something so general

[grave bear]

None of that even helps him

[undone coral]

in my opinion almost 100% of the code written here is "wrong" in the sense of going down a losing path

like there isn't a way to rescue this approach really

the game might not be a general parkour game. it sounds like it could be an infinite runner, really, where sometimes you go onto walls. totally different problem

[grave bear]

How does any of this help him

It doesnt

[round pawn]

Exactly

[grave bear]

To summarize, when you push forward and let got, the velocity should maintain that heading regardless of orientation. But for you, it's "following" the forward direction of the player? Does this sound about right?

[round pawn]

Yesterday I even commented on how people will find endless irrelevant things to nitpick when you share code, lmao

[round pawn]

Yep, exactly

Other than that the code functions well

[undone coral]

sorry about that, good luck on your journey

the game sounds fun

[grave bear]

@round pawn I think I understand the issue you're experiencing

[round pawn]

What's your take? So far all my diagnoses have failed

[grave bear]

Does that look about right?

@round pawn

[round pawn]

Uuuhm, not sure what you're trying to show me

Are you trying to reproduce the bug? If so I can walk you through it

[gray pulsar]

have you tried using the rigidbody rotation methods instead of rotating the transform?

Rigidbody.MoveRotation or AddTorque?

or Rigidbody.rotation?

[round pawn]

I could! I'll try it

[grave bear]

Vector3 wasd = new Vector3(Input.GetAxisRaw("Horizontal"), 0f, Input.GetAxisRaw("Vertical")).normalized; @round pawn

one of these wasnt the same

[round pawn]

Ok, fixed that

[grave bear]

GetAxis is interpolated. GetAxisRaw is not

[flint geyser]

---

I'm creating an EditorWindow to aid in placing Camera right in front of the inspected character's head. So I've created a Camera which renders to a RenderTexture and I've placed an Image with the RenderTexture inside the EditorWindow and the EditorWindow shows up when I'm starting to change the supposed location for the Camera. But the Camera created to assist in choosing the appropriate location for the in-game Camera captures real (in-game) space instead of prefab mode space where it is used. How do I make it capture prefab mode space instead?

[round pawn]

Welp, you just fixed my issue. I had thought I tried using GetAxisRaw, but I had forgotten to change both input checks

Much appreciation

I feel dumb

[grave bear]

yep np! In the future, always presume the error starts from the input and work your way down 🙂

[grave bear]

I've done worse lmao

[undone coral]

have you looked at this asset store asset? https://assetstore.unity.com/packages/templates/packs/first-person-parkour-system-v2-0-for-playmaker-168546

it looks really really good

if i were doing this i would study how it is put together

you don't have to use it but you could at least research it

[flint geyser]

They are discussing a different aspect of their problem and don't seem to have problems with rendering active scene space instead of prefab mode space

[gray pulsar]

ah, your problem is which coordinate system the camera is using for positioning, not which scene the camera is rendering?

[flint geyser]

No, which scene is used for rendering, seems like people in your link provided Camera.scene hint, I'll try to use it

[hazy epoch]

Why did my Debug.Log messages suddenly start showing up with a weird prefix? 0x0000xxxxxxxxxxxx ...where "x" are characters that always change.

[flint geyser]

Solved with Camera.scene = PrefabStageUtility.GetCurrentPrefabStage().scene;

[hazy epoch]

Got it...but that prefix never existed before on any Debug.Log. I'm just wondering where it suddenly came from.

[sly grove]

something's broken with like... debugging symbols?

[hazy epoch]

It's literally just a Debug.Log with a string in it.

It's not like a NullRef error or anything. Just a log I put in the code.

And it's never done this before. Not in the 2 years this project has been going.

Hey, so, can someone code this? I have no idea what to do reading this but I'll get a better understanding if I'm reading the code

[shadow seal]

You actually want someone to write it for you and hand you the code

[undone coral]

you can create a prototype using MudBun. the cross section would be a big box subtraction

there are also CSG assets. you can use Poseidon at runtime. works well and fast

you would make your level mesh, then subtract away with a big ol' cube in Poseidon. that's it

[fresh salmon]

Links if needed:

MudBun - $67 https://assetstore.unity.com/packages/tools/particles-effects/mudbun-volumetric-vfx-modeling-177891
Poseidon CSG - $45 https://assetstore.unity.com/packages/tools/level-design/poseidon-csg-dynamic-level-design-159427

[hollow garden]

[fresh salmon]

It's probably less expensive to buy these assets and let them do it all for you, than hiring someone that will program it for you (don't expect people to work for free).

[hollow garden]

or (get this) you could spend some time and figure it out and code it yourself

[fresh salmon]

Nah, they were sent here to ensure we feed our overlord the Á̴̺ş̶͠s̷̞̿e̸̱̾t̴̰͐ ̷͕́Ś̵͇t̵̰͝ŏ̷͍r̸̙͊e̷͛ͅ

poseidon csg is pretty good

if the user can figure out how to make a bunch of cubes together,

poseidon can solve the problem of getting the cross section

whaddya think @regal olive ?

[fresh salmon]

I don't doubt the efficiency of the asset, for something paid I would expect the features to be at least decent anyway
But it would be good to link the page directly, or mention that it's a paid asset in the original message

A matter of principle, so they don't waste time dreaming on something if they can't afford it in the end

There is a player and a blue mech robot behind it. The blue mech is following the player like looking in the direction of where the player is looking so they shoot simultaneously. Technically the object it follows is the empty object called a shooting point attached to the gun's tip so that the mech is aiming where the player gun is aiming so that they can look aligned. But the problem is when the player animation is playing like the player moving forward and backward or player rolling etc I don't want these actions to be copied by the mech robot it looks weird but unable to find a solution to stop the mech rotation when the player's animations are running it should remain calm when player doing it's animation action just follow the player look not follow any other action.

This is the line in the image where the mech follows the player's shooting point in the shooting function this function has been called in Update.

[woven kettle]

hey,

I'm trying to add a force to an object with riggidbody in the right direction, the force is supposed to force the objcet to leap in the direction of the force (like a push from an explosion)

to determine if the object was hit or not i used (transform.position, radius,new Vector3(0,0,1),0) (*the vector3 is direction, the float at the end is the maxDistance *)

the problem is, when I tested that, RaycastHit.point is always Vector3.zero ... so the force is also always = ZERO

why is the Hitpoint = V3.zero?????

[drifting galleon]

if you want explosion force, there is a method for that already

[woven kettle]

its more than a punch than an explosion

[sly grove]

to determine if the object was hit or not i used (transform.position, radius,new Vector3(0,0,1),0) (the vector3 is direction, the float at the end is the maxDistance)
You used that... where?

[woven kettle]

on update

[sly grove]

but...

wdym

is it a raycast?

overlapSphere?

[woven kettle]

Physics.SphereCastAll(), sorry, i forgot to mention that.

[sly grove]

Why use Spherecast if the sphere isn't moving

use OverlapSphere

a spherecast that doens't move will never detect anything

because they don't detect things that the spherecast starts inside

[woven kettle]

I want to take advantage of the hitpoint property of the Physics.SphereCastAll()

[sly grove]

but it doesn't make sense

it won't work the way you want

there is no hit point if the sphere is not actually being cast

[woven kettle]

?? how its not casted ? its being casted in place on update

[sly grove]

because you set the distance to 0

[woven kettle]

so it should be casted at zero point all the time

[sly grove]

You may want to read the docs:

Notes: For colliders that overlap the sphere at the start of the sweep, RaycastHit.normal is set opposite to the direction of the sweep, RaycastHit.distance is set to zero, and the zero vector gets returned in RaycastHit.point. You might want to check whether this is the case in your particular query and perform additional queries to refine the result. Passing a zero radius results in undefined output and doesn't always behave the same as Physics.Raycast.

it explains why your point is the zero vector, it says it right there

https://docs.unity3d.com/ScriptReference/Physics.SphereCastAll.html

[woven kettle]

:S yeah

[sly grove]

anyway all you need to do is add a force from the center of the "explosion" towards the object

hitObjectPosition - explosionCenter```

[woven kettle]

this script runs on the hammer script, i was thinking something like that

 Vector3 dir = (transform.position - objTransform.position).normalized;

would that work ?

[sly grove]

assuming the script is on the object you want to be pushed and objTransform is the center of the explosion

then yes

if not, no

maybe you want the opposite?

a - b gives you the direction from b to a

[woven kettle]

I'm having an unexpected results, not sure what is causing it, but when I move the hammer forward a little bit fast, the object flys in the direction of the hammer instead of hit :S

and that happens quite often :S

as if the object being thrown backwards!

[jolly berry]

Not sure where to ask this so sorry if this isn't the write forum...but does anyone know of this trick where you place your different menu screens and panels outside of the camera view so they're easier to see and manage in the editor? (Instead of having all of them layered on top of one another and clicking hide and unhide constantly.) Thought I'd ask the advanced coders since this might be a trick you use. I remember seeing a tutorial that used this trick but for the life of me I can't remember which one it was, because I want to use it but don't remember the details.

Just knowing what this tip is called would help me google it.

[ember temple]

Do you mean rearranging the editor windows?

[sly grove]

show the code? Did you reverse the positions?

[jolly berry]

no, it's like a trick you use if you have, let's say, a lot of different menus. instead of having them all layered on top of one another in the game space, you have them moved outside of the gamespace so when you zoom out, you see the gamespace in the middle, and all the menus laid around it. and then when you run the game, all the menus somehow magically align into the gamespace where they should.

sorry, i'm still learning unity so not sure what the terminology is to describe this

it just makes it easier to edit different menus, since you don't have to click them on and off all the time

to get them out of the way

https://forum.unity.com/threads/best-practices-for-editing-positioning-multiple-menus.434230/ This person describes the problem

The guy in the tutorial I was watching did #1, but I can't for the life of me remember how he did this.

[woven kettle]

yes that helped a lot, although sometimes it makes an awkward and unrealistic results but not as common as it were before.
thanks a lot 🙂

[drifting galleon]

well just as he says. write a script that moves the elements on demand.
another thing i would recommend: use UI Toolkit

[jolly berry]

thanks, i'll take a look at the toolkit!

Hi! I am facing a really strange issue here. I have my game witch does work perfectly on the editor, but when I build it, everything works just fine except the texts on the UI do not update!, they just show the default values they had in the editor.
I am updating the texts by code using "myText.text = value;"
Also, I am not getting any errors, I made a development build but there is nothing...
Is this a known issue? I've been searching online but couldn't find anything helpfull

[kind bison]

ok!

[amber silo]

Try doing script debugging on the build to see if something weird is happening?

[quaint geyser]

I didnt know you could debug your build! I will check it out and see if i find anything

Is there a way to get current position on a spline(I am using Dreamteck Splines)

[rotund kestrel]

How do you usually approach figuring out what a native crash is from when is just unity libraries? We have logs in firebase but we can't make much sense out of it even if it is symbolicated for android.
It seems to be all over the place and can't find any patterns, the crash itself in crashlytics shows like:

I need some serious help

nobody in the beginner channel

or unity forums can help me

my terrain editor is completely broken

I just cant progress in my project any more

Ill send a video

https://screenrec.com/share/Ek06QiPDXY

[regal olive]

It’s not a coding question, go to #⛰️┃terrain-3d

[azure meteor]

oh ok cool

[regal olive]

Or #💻┃unity-talk

[azure meteor]

ty

[fresh salmon]

"nobody in the beginner code channel"
looks at terrain channel
at most 3 messages per day
lmao

[compact ingot]

best way to make a channel lively is to post interesting questions there... "fix my broken app" questions are very uninteresting to most people

[mortal orchid]

I have tried this solution. It kind of works but is not that effective. I access the blend animation float parameter and see of the animation is running or not

[placid nest]

Hello, I'm currently creating my own networking tool because no other solution really fits my project. To keep everything simple and clean for other developers who have no knowledge about networking I want to send network messages by just calling a method with an attribute on there. Example:

void Test(){
 // Executed on client
 DoThis();
} 

[Server]
void DoThis(){
 // executed on server
}

Basically when the client executes this method I only want him to tell the server to execute it and send parameters through if needed and on the server actually execute what should happen in the method. I've been searching alot on this topic on google, but couldn't find anything at all

I know how to create a new attribute, I just don't know how to change the behaviour of things when I've created a new attribute

[austere jewel]

Don't cross-post.
Also, if you just post massive systems nobody can help you, debug it with the debugger so you at least have smaller problems to present.

[novel plinth]

uh.. knowing how to make custom attribute without knowing the existence of Reflection is just.. uh...

https://docs.microsoft.com/en-us/dotnet/standard/attributes/retrieving-information-stored-in-attributes

[placid nest]

i know about the existence of reflection

[jolly berry]

thanks for this! i don't think this is what i originally saw but it has what i need to do the job. much appreciated 🙂

[thick cloak]

Anybody expert on Perlin noise? I have this super simple script that generate mesh. But I want to apply Perlin noise to the up vector, but every time I try, I doesn't apply for the individual vertices, but instead for the whole plane's height.

[sly grove]

you're only setting one vertex

the 0th

vertices[i] = but i is always 0

oh wait sorry missed the i++

Your code is a bit hard to read though due to the weird indentation

[hoary pendant]

Also you haven't posted your perlin noise implementation

Also #854851968446365696 for how to post code

[sly grove]

oh yeah - don't see any perlin noise haha

[thick cloak]

This was my solution, which didnt work

[sly grove]

the problem is you're using integers as the inputs to the noise function

try Mathf.PerlinNoise((float)x / size.x, (float)y / size.y)

the noise function will always return the same value for integral inputs

[thick cloak]

OMG!! It worked

Thank you so so much!

[spare elbow]

i am saving my SaveState class with xml serialization

when i add a new list attribute to the class the serializer has problems deserializing the old savestate class into the new one

this is what is gonna happen when the players update their game

so what is the best way to handle this issue

[compact ingot]

custom serializer that understands the migration from the old to the new type

[spare elbow]

ok

i guess ill have to learn much more about xml to do that

simple youtube tutorials wont do it this time 😄

[compact ingot]

its not in the XML; its something you code yourself and inject/add to the serialization library you are using

[spare elbow]

so this is how i load for example

        if (File.Exists(path))
        {
            saveState = SaveHelper.DeserializeFile<SaveState>(path);
            Debug.Log("loaded save file");
            load_completed = true;
        }
        else
        {
            saveState = new SaveState();
            saveState.Init();
            Save();
            Debug.Log("initiated save file");
            load_completed = true;
        }```

i have to change this right?

[compact ingot]

depends on what SaveHelper does

[spare elbow]

    {
        
        var serializer = new XmlSerializer(typeof(T));
        var stream = new FileStream(path, FileMode.Open);
        var container = (T)serializer.Deserialize(stream);
        stream.Close();
        return container;
    }```

[compact ingot]

any particular reason you are using XML btw?

[spare elbow]

not really

thats kinda what popped up when i looked up how to save

[compact ingot]

its probably less work to do this with JSON

[spare elbow]

does json also have this issue im gonna have to deal with

[compact ingot]

yes

[spare elbow]

hmm

[compact ingot]

but its quite simple to write a custom serializer that can handle the migration

[spare elbow]

ok ill look into it

thanks

[compact ingot]

and just based on the fact that XML is a massively overengineered piece of tech, you might have an easier time doing it with a simpler format like json

[spare elbow]

alright

[regal olive]

Anyone know anything about the performance difference between having a ton of .JSON files VS having one very long .JSON file? Specifically, if I need to serialize the positions of every character and their inventory for instance.

My thoughts are that if you have multiple each one contains the data for only that one NPC then the serializer will have to look through less lines to find what it needs. But I'm not aware of any game that saves hundreds of .JSON's, one for each NPC, so wondering if that's not the case?

EDIT: I suppose you only serialize from once and then its stored into memory through the in-application properties. So maybe it doesn't matter?

[sly grove]

Managing multiple files seems like a nightmare. Why would you want to subject yourself to that

most of the time save files are not big enough for it to be a huge concern

if you have enough data where that's a concern you'd probably look into a different approach like using a database instead

[regal olive]

Actually it would be easier to do one for each but it would be bloated

[compact ingot]

If you have complex persistent data to save, query and update incrementally, use a single-file database like SQLite or liteDB

[inland delta]

i would split separate things into separate json

like i did in my game

[calm ocean]

Does anyone know the difference between scriptable object's create instance and instantiate?

[hoary pendant]

One makes an asset file, one makes an object

[gray pulsar]

CreateInstance is like a constructor, while Instantiate is like a Clone method

both of them make runtime instances

and if you want to save an asset file you need to save it out with AssetDatabase

[calm ocean]

So it's like the difference between creating a new game object and filling it with data and instantiating a prefab?

[gray pulsar]

yeah, similar

CreateInstance will create it with all its default values

while you can pass an instance into Instantiate and the new copy will have the values of that instance instead

[hoary pendant]

Ah okay, forgot you had to make an asset after CreateInstance. Usually never use that method anyways as they are not what SO was intended for

[calm ocean]

I see, thanks for the help

[calm ocean]

Why not?

[hoary pendant]

Hmm I suppose you could save a new asset during runtime if you wanted for persistent data. But usually you use it as data created thru inspector

[calm ocean]

I haven't had a chance to create a new asset during runtime as well. I have just been experimenting with different ways of working with scriptable objects

But I suppose it could be useful for things like inventory management

[hoary pendant]

Like generating a brand new item or an ingame editor

[calm ocean]

Yeah, and you can save the items in your inventory

Just a thought, not sure how practical it is though

As opposed to just keeping a list of regular classes

[gray pulsar]

yeah, it adds a bit of editor functionality, but no real benefit to game code over regular classes

[calm ocean]

Would the draw backs be large? Say, performance or memory wise?

If the benefit of editor functionality is free, I see no reason to make everything a scriptable object

[hoary pendant]

Not really SO is a simple data container, but organization is probably inefficient

[undone coral]

is it possible to ask a unity camera to render to some other native texture? for example, can i somehow set the native texture pointer on a unity render texture?

[calm ocean]

Not really to the editor functionality part or to the draw back part?

[gray pulsar]

the CreateInstance => AssetDatabase path is useful for custom inspectors for constructing SOs, though. Like if you want to make a wizard for setting up a complex object and save it out or w/e.

[hoary pendant]

Read/write to SO at runtime and finding the files after creation

[calm ocean]

So performance wise that's not an issue?

[hoary pendant]

Shouldn't be, but the organization may be messy

[gray pulsar]

probably not 100% free, but definitely not large overhead

[calm ocean]

I did something like that be for a dialogue system. A class would read a file and convert each line to an instruction, and store the instructions as a list to a scriptable object.

[undone coral]

can i ask unity to render a camera to a texture2d created via a plugin instead of a render texture?

or, is it possible to back a render texture with a different native texture whose lifetime i manage?

[keen cloud]

Anyone know why this code is giving me this error?

[fresh salmon]

You'll have more luck and a faster answer asking this in a C# server instead.

[keen cloud]

i mean its part of my game lol idk i just asked here first

[fresh salmon]

Unity does not use the static Main entry point

[compact ingot]

show your using statements?

im making my game make this program to execute it

[keen cloud]

there are none im just doing it manually

[compact ingot]

and what do you do to get those errors?

[median cosmos]

hey I'm kinda stuck with this issue. I'm trying to spawn tree (in 2D) with a random z rotation between -10 and 10 so it feels more organic but I can't figure out how to calculate how much to move the sprite down so there won't be any space between it and the ground. the ground and the bottom of the sprite are both perfectly horizontal (no slopes etc.)

does anybody know how to do this?

[sly grove]

just make the bottom of the tree the pivot

so you don't have to think about it

[median cosmos]

no the issue is that I already placed the trees everywhere and that I also spawn them with a random size and position them via code after so they also lign up on the ground

I can't figure out though how to do the same with z rotation

[sly grove]

yeah sounds like making the bottom of the tree the pivot would be fine and work perfectly with that

you can just set the position to the ground's y position and it'd work fine

it'll make your other code simpler too

[median cosmos]

okay but that wouldn't help me with the problem would it? I spawn them with a random rotation

so I would still need to reposition the trees after

[sly grove]

why would you need to reposition anything

[median cosmos]

also, the sprite's middle perfectly works as the pivot

[median cosmos]

I spawn them with a random z rotation in Start()

[sly grove]

if you have the bottom as the pivot

[median cosmos]

no

[sly grove]

this is a before/after rotation

easy

[median cosmos]

I will send you a photo

see?

it works in the middle but not on the right side

[sly grove]

set the pivot a little above the bottom then.
Or do the trigonometry

[median cosmos]

but they spawn with a random rotation so that would mean the pivot would be different for every rotation

yeah I've already tried the trigonometry solution but I'm not good at it so it didn't work

[sly grove]

trigonometry will give you the value of d

[placid violet]

Math 😱

[sly grove]

given that distance T (half the width of the tree trunk) and the angle theta (which you chose randomly)

[median cosmos]

sorry I think I didn't explain my issue enough: every tree spawns with their own random rotation

[sly grove]

then it's just SOH CAH TOA

[median cosmos]

ah thank you

[sly grove]

that is understood

[median cosmos]

oh ok

[sly grove]

you have sin(theta) = opposite/ hypotenuse

so sin(theta) = d / T from the diagram

You should have the value of T (it's half the width of your tree trunk), and theta(you chose it randomly), so you can solve for d

which is how far down you need to move the tree into the ground

d = sin(theta) * T

[median cosmos]

thanks so much!

[sly grove]

just make sure you express theta in terms of radians if you want to use Math.Sin

[median cosmos]

yep did that already

hmm

still doesn't work correct

I did this

wait wut

so I'm kinda confused what do to with Math.Sin() so if I should put Rad or Deg in it

it says it uses an angle

doesn't this mean it's already an angle?

so I don't need to do anything?

hmm no doesn't do anything

ups I think I found the issue

[sly grove]

looks like you're moving the object on the z axis?

[median cosmos]

omg

I'm so dum you're right

I also used the x scale and not half the x scale

so do I need to use Mathf.Deg2Rad since I already have the rot as an angle?

ahhhh wait a sec

nope still doesn't work

you can ignore the scale thing and first position offset since I tried that and it works alright

[sly grove]

it should be Mathf.Sin(rot * Mathf.Deg2Rad)

[median cosmos]

I tried that as well already

didn't work either

[sly grove]

also are we sure that localScale.x is the width the tree trunk?

[median cosmos]

hmm you're right once again

imma do it correct once again

still doesn't work

the 100 smth - 99 smth is the exact width of the tree trunk

[sly grove]

what's it doing?

[median cosmos]

wdym?

[sly grove]

you said it's not working

it's doing something right?

[median cosmos]

it's still like this

it does something, but the difference between the trees is really small

this one for example works better

[sly grove]

do the trees have a parent object?

[median cosmos]

nope

no child objects either

and only a sprite renderer

and only one script each which I just showed you

[sly grove]

hmmm, not sure really what's missing here, other than possibly that tunk width being wrong

or my math being wrong 😛

Or your original height adjustment could be slightly off too

[median cosmos]

well I can test once again

nope it works perfectly fine

you did notice that the rotation I generate is already in angles and not in rad?

[hoary pendant]

I mean he already gave you the general pseudocode for how to solve it, since this is #archived-code-advanced , you be able to should find a way to achieve that feat

[median cosmos]

yeah I'm just wondering if he noticed this

[hoary pendant]

regardless of semantics, the concept is there and you can see if it was right or wrong thru the docs

[median cosmos]

or if he didn't see it and thought they were actual rad numbers

yep well thanks for the help!

[sly grove]

yes exactly

they need to be radians for sin

so you need to convert degrees to rad to use sin

[torpid blaze]

Hey peeps, basically I want my script to have editable rotation values and not to follow the cursor (my position values are editable in the inspector so I want the rotation values to be editable too) please help me!

Is there any way to make Unity Poll for event data faster that is not based on FPS?

[timber flame]

Simple task scheduler
Do you know any better maybe more efficient way to raise an event periodically for some tasks?

 public class TaskScheduler
    {
        private readonly int _fixedRate;
        private readonly List<TaskData> _tasks = new List<TaskData>();
        private CancellationTokenSource _cts = new CancellationTokenSource();

        public event Action<int> Raised;

        public TaskScheduler(int fixedRate = 1)
        {
            _fixedRate = fixedRate;
        }

        public void Add(TaskData data)
        {
            _tasks.Add(data);
        }

        public void Remove(int id)
        {
            var index = _tasks.FindIndex(task => task.Id == id);
            if (index >= 0)
            {
                _tasks.RemoveAt(index);
            }
        }

        public async void Run()
        {
            try
            {
                while (true)
                {
                    await Task.Delay(1000 * _fixedRate, _cts.Token);
                    foreach (var taskData in _tasks)
                    {
                        taskData.RemainingTime -= _fixedRate;
                        if (taskData.RemainingTime > 0) continue;
                        Raised?.Invoke(taskData.Id);
                        if (taskData.IsRecurring)
                        {
                            taskData.ResetRemainingTime();
                        }
                        else
                        {
                            Remove(taskData.Id);
                        }
                    }
                }
            }
            catch (TaskCanceledException e)
            {
            }
            catch (OperationCanceledException e)
            {
            }
        }

        public void Cancel()
        {
            CancellationTokenGenerator.CancelAndCreateNew(ref _cts);
        }
    }

For example, in city building games, there are many buildings generating some stuff (food, wood, meral, etc. every n seconds)

[undone coral]

can canvases be baked? instanced? if i make no changes to the hierarchy of a UGUI canvas, in world space for example, it is not rerendered correct? is there an asset that does this?

[sly grove]

I see two problems here for that type of game, both linked to the same kind of issue:
1 - Unity's async implementation relies on checking in on things once per frame. This means that your await Task.Delay is going to have some error introduced to it by that process. the await time will be the minimum time to wait, and then it will resume on the next frame after that minimum. Meaning if you ask to wait for 1 second, you may actually wait 1.05 seconds for example. This error will accumulate over time. So your tick system will already not be very consistent.

2 - similarly, the way you are doing this is slightly problematic too:

if (taskData.IsRecurring)
{
    taskData.ResetRemainingTime();
}```
If the recurring task is supposed to recur every n seconds, and your fixed rate doesn't divide evenly into n, you are throwing away some time there, and the recurring task won't recur perfectly over time

The net result of all this is that your "fixed" timers are all subject to small but cumulative error over time. This may or may not bother you, and may not even be immediately noticeable. But if your game were ever to become popular with, for example, speedrunners or build up any kind of enthusiast community, It would be an issue.

[undone coral]

you can look at UniTask, which has an optimal task scheduler

you should use it as your async solution

i think unity plans to adopt it first class

if you want a recurring task that would seemingly be part of the task itself

you also can't really delay on the main thread like that. if you are in a threadpool, you should use unitask

[tender light]

Wait what?!?
Thats awesome. Where did you hear that? When is that happening?

[novel plinth]

Pool those token sources somewhere, and dispose them on scene changes and OnDisable..

Depends on your Unity version, in 2022 we now have MonoBehavior.destroyCancellationToken which makes asyncs make more sense to use now

[magic reef]

Im trying to have unity read a file, ill i want to ask is what the difference is between these two directories, because for some reason unity accepts the second one, but not the first one, im pulling the first one from a textmeshpro.text string but it doesnt matter since even putting it into unity through note pad wont work

im not shitting you when i say unity takes these two seperate file paths differently and chooses one over the other

[sly grove]

Probably some invisible character difference

Look at them in a hex editor or do a character by character comparison in code if you want to know for sure

[tough knoll]

Not that the trig is not a good solution, but has it occurred to you to just inset all the trees by a small amount which is enough to make even the most rotated tree look good xD.

Hey I got a code question

It's more like a math question but

I'm generating a procedural train track by using a sort of spherical coordinate conversion kind of thing

To generate the curved line, I give it a length and angle and then use this function:

Vector3 theta = new Vector3( Mathf.Sin( angle * t * Mathf.Deg2Rad ) * length, 0f, Mathf.Cos( angle * t * Mathf.Deg2Rad ) * length );

It gives me vectors along a circle, then I add those together to make the curve

So that works great on one axis, to do the other axis it would be like:

Vector3 phi = new Vector3( 0f, Mathf.Sin( angleY * t * Mathf.Deg2Rad ) * length, Mathf.Cos( angleY * t * Mathf.Deg2Rad ) * length );

How the hell do I combine the Z components to make it a 3d curve?

(t is the point along the curve from 0 to 1, this is like an evaluation function)

Not sure what even to google

[undone coral]

it was in a blog post of theirs

they specifically called out either unirx or unitask

i forget which

[grave bear]

For the life of me, I cant seem to get ILPostProcessor to work correctly with Mono.Cecil. It works perfectly fine in my console apps compiled by VS. For reference, this is all I'm doing as a test in unity and a console app:

if you dont want to compile it yourself, use Dotpeek or something similar to inspect this .dll

[undone coral]

i felt like i just read a forum post about specifically this

i think unity forums discusses this exact issue

[undone coral]

what's the objective?

[grave bear]

@undone coral I'm currently diagnosing the issue further as I managed to actually write to the assembly without issues using the above code in similar context. Rewriting everything atm

[undone coral]

there apparently is an official unity splines package that may help you. bezier lines like it can perfectly produce a semicircle. it's not super clear what you are trying to do. you can use a quaternion to rotate a vector small amounts - it would point to the track.

[grave bear]

serializer

[undone coral]

like to emit IL for optimized serialization routines?

[tough knoll]

Splines are a bit overkill for this use case : p Just trying to draw an arc

[undone coral]

okay the simplest way is

[grave bear]

yes. I already have a plan in that regard. The difficult part is just getting cecil (unity?) to actually do what it is designed to do

[undone coral]

Quaternion.AngleAxis(deltaPhi, Vector3.up)*Vector3.right

do you see what i am doing?

[tough knoll]

Yeah, and then just combine the quarternions I guess

I thought of turning them into quaternions for the add but I was trying to figure out how to do it mathematically so I could understand

[undone coral]

you're basically pointing at the arc, then rotating where you are pointing little by little

to draw it out

[tough knoll]

I just kind of want to understand how to combine spherical coordinates

[undone coral]

angle axis is a great way to do spherical coordinates

it will illuminate that an orientation is related to spherical coordinates by choosing a canonical value for what theta=0, phi=0 is, which i believe is Vector3.right

i.e. (1,0,0)

then you rotate about the axes (0,1,0) and (0,0,1)

[tough knoll]

I guess I should just read up on what happens when you have a quaternion multiply

[grave bear]

think of it as "adding" to a rotation

[tough knoll]

I understand the concept. Just not sure on how this translates to combining spherical coordinates when translating them to cartesian

[grave bear]

What was your original question?

[tough knoll]

So like

to calculate theta and phi in cartesian coordinates

Vector3 theta = new Vector3( Mathf.Sin( angleX * t * Mathf.Deg2Rad ) * length, 0f, Mathf.Cos( angleX * t * Mathf.Deg2Rad ) * length );

Vector3 phi = new Vector3( 0f, Mathf.Sin( angleY * t * Mathf.Deg2Rad ) * length, Mathf.Cos( angleY * t * Mathf.Deg2Rad ) * length );

But then how does on combine the cosines into the Z component for a 3d arc instead of a 2d arc

[grave bear]

What's the end goal?

[tough knoll]

I'm generating a track for a procedural corridor background to follow for a train level. I'm aware there's like 9 million other ways to generate this curve, this is just the way that I picked and it made me aware that I don't really understand spherical coordinate conversion

I have a working solution for the actual project already, I was just curious if someone with a higher math education could illuminate me

[grave bear]

Is the corridor suppose to align to a fixed axis?

[tough knoll]

It doesn't have to, to actually generate the walls I sample a "center" position on the track and then sample other points for the walls in both directions and I get those vectors in the local space of the center

so it could really be facing upside down for all I care, it's just the relative curve from the center to the further walls that matters

[grave bear]

The further walls would be the walls in say a tunnel right?

[tough knoll]

Yeah

like this

But the code I posted just has to do with the generation of the track, this is all other unrelated stuff

[grave bear]

and those need to be aligned to what relative rotation? world space?

[tough knoll]

The blue vectors I'm getting in the local space of the green vector, and then I'm transforming the walls of the tunnel relative to where the player is standing to follow the same curve

so it looks like you're on a train car moving through the curve of the track

[grave bear]

the train car is in a fixed position? this is all "faked" to make it look like you're going through a tunnel?

[tough knoll]

Yup

[grave bear]

ah gotcha

[tough knoll]

To simplify physics and pathfinding inside the train xD

[grave bear]

makes sense

[tough knoll]

And also that way the player always exists in the relative direction of motion of the train, so it's less disorienting

[grave bear]

do the train do any sort of unnatural bends like loops or hard turns?

[tough knoll]

My generator has an angle limit of 15-45 deg. for turns right now, so not really

but I guess it could

Sometimes it loops over itself... Kind of silly but hard to tell since you're not seeing it from top down

and since the generated segments cease to exist when they're further than draw distance away from you, haha

I'm using mesh skinning to bend the walls to follow the curve, it looks really neat

[grave bear]

you can use the curve anchor to determine rotation. the larger the relative position delta (left or right) will determine a "pull" to the left or right respectively

[tough knoll]

Well, that part is easy, my question regarding coordinate conversions had to do with my method of track generation

[grave bear]

using an actual curve library would most-likely give you better results and make it easier to implement features

I have a few curve functions you can use if you want

[tough knoll]

But this track looks so good!

Could you show me an example?

of a curve function

My requirements were that they rotate smoothly along the selected distance for that track section and look mostly spherical

[grave bear]

https://github.com/Extevious/Curves/blob/main/Runtime/CurveFunctions.cs

[tough knoll]

This is the output of my current one

Wouldn't I end up having more work if I use a parametric curve? because to make it perfectly spherical I then have to figure out where to put the control points to create that type of curve, right?

[grave bear]

the tunnel is perfectly spherical?

[tough knoll]

No, I mean the curvature of the turns

here look

[grave bear]

oh, you mean the the handles

yeah, a little extra work

[tough knoll]

But doesn't that put me back in the same problem of using trigonometry to convert a spherical coord to cartesian

[grave bear]

likely not because you can easily determine the mirror of the handle using just the coordinate system

[timber flame]

Absolutely true, my second question after that. Yes. Accumulated error.
To solve it, I should use for example Time.time or DateTime and according to it, accumulate these small values?

[grave bear]

also, you would want to use an actual bezier curve, like the CatmullRomCurve function I got.

[tough knoll]

Would the correct control point always be just the intersection of the two lines?

like so

[timber flame]

Thanks but what do you mean? delay on the main thread
you mean it is better to dedicate another thread instead of awaiting on the main thread?

[grave bear]

for a perfect curve, then yes

but you dont need to do that if you want more chaotic curves that are not uniform

[tough knoll]

It kind of seems like my solution is less complicated if only uniform curves are required

I mean it is literally like one line right

[grave bear]

wait you want perfectly spherical turns between points?

[tough knoll]

Yeah

Basically like, I'm getting a series spherical coordinates forming the angle of the turn, translating them into cartesian coordinates to make them a bunch of direction vectors and then the sum of those is the track's line

[grave bear]

oh I thought you wanted some "natural" turns like when driving on a road in the mountains

[tough knoll]

I just don't know how to properly combine the multiple axes. I did in fact read a book but I think I'm looking up the wrong stuff because the normal method of converting spherical to cartesian doesn't seem to work with my code

[stuck onyx]

anybody using Unitask? I'd like to know which one of these is the right one to indicate to continue in the next frame:

"await UniTask.Yield();
or await UniTask.NextFrame():"

or are they just the same ?

[untold moth]

you could use the plain C# Task.Yield() in that case

[thin mesa]

https://cysharp.github.io/UniTask/api/Cysharp.Threading.Tasks.UniTask.html#Cysharp_Threading_Tasks_UniTask_NextFrame

Similar as UniTask.Yield but guaranteed run on next frame.

[stuck onyx]

thanks humans

[median cosmos]

yep that's exactly what I did after that, not a perfect solution but it seema to be working at least

[stuck onyx]

I'm having a bottleneck on a script i created to transform my 3d map in 16 different textures... capturing, rendering, copying to texture all works fine and i was able to distribute it well in different frames so its done in 'background' seamlessly....
But when it gets the moment to encode the texture to png the game lags, (it takes 70-90ms) aprox... I tried setting

await UniTask.NextFrame();
await UniTask.WaitForEndOfFrame();````

before and after the encoding but still the game lags when the operation is being done

is there any way around this?

[regal olive]

im trying to make moving mesh reparenting script for a very complex mesh with climbing, and with big moving parts. I have a script for it but i have to make a trigger box above it
and that does not work very well
any ideas?

[rugged radish]

I'm using the Job system to solve a similar problem, worked really well

pretty sure compute shaders can help there too, never used them tho, so I don't know for sure

[stuck onyx]

could you give me some hint to what to google for?

[rugged radish]

"unity job system"
the documentation is pretty good as is, only encountered one unclear moment that people from this channel helped me to clear
I'm also using it with async calls, so should be easy to plug it in for you

[stuck onyx]

thanks a lot

[obsidian glade]

plenty of resources available that explain the concepts & how you could go about implementing one

[grave bear]

OK lmao I figured out why Mono.Cecil wasn't "working" as expected. Do not read the symbols when reading the compiledAssembly. From what I can tell, cecil reads them as a template for underlying types and methods. HOWEVER, it will include new types added (which explains why adding a type worked, but adding a method to an existing type, didnt.) The actual compiled assembly worked as far as I can tell, but dotpeek wasnt actually able to detect changes in the actual assembly. @undone coral since he took interest.

now, depending on use-case, using the existing pdb might be desired as it maintains the original layout of the assembly, with the exception of added types.

However, for debugging purposes, using the generated pdb from cecil is much better imo

[undone coral]

sounds like it needs to be asked to re-read or refresh its view of an assembly's types

[grave bear]

Dotpeek?

dotpeek refreshed, it's just that the underlying types didnt change. Only changes that took place were the addition of types.

[grave bear]

I manage my own StateMachine library that behaves very similar to a BT. Start with understand the StateMachine logic first, as it will make understanding a BT much easier

[obsidian glade]

https://learn.unity.com/project/behaviour-trees

[grave bear]

basically yes. My FSM however is much simpler than a lot already out there with the added benefit of having a deterministic state pattern (basically a simplified BT)

[calm ocean]

Is it possible to iterate through a set, for each item, do something to it, and remove it from the set, in an efficient way? A foreach loop wouldn't work because I would be modifying the set as I am iterating through it. I thought of using a list instead of set so that I can do a counted for loop backwards, but then when I remove from the list, I am afraid that it would be inefficient. Any thoughts?

[grave bear]

best solution for pattern removal is to use a reverse for loop

[calm ocean]

Oh I see, so calling .remove() from the list is inevitable?

[grave bear]

no

there are collections out there that implement a RemoveAtSwapBack method that removes the element at index and replaces it with the last element in the array. Do note that the order of items will be scrambled when you do this

[calm ocean]

Oh I see, so if I don't care about order that would be the solution I am looking for

[grave bear]

yes

[calm ocean]

Awesome, thanks

[grave bear]

also, if you need to maintain order, using a list and RemoveAt will be faster than Remove since Remove has to compare each element in the list @calm ocean

[calm ocean]

When you say there are collections out there that implement RemoveAtSwapBack, do you mean not native to c# and other people's implementations? I can't seem to find any collections native to C# that have remove at swap back.

[grave bear]

I personally dont know of any native .net collection that implements RemoveAtSwapBack. I have a little collection library you can use that has the same functionality: https://github.com/Extevious/Collections/blob/main/Runtime/SimpleList.cs

[minor nexus]

I have a script in unity which makes a linecast between two points over potentially thousands of iterations. Would this be a good candidate for multithreading using the job system and if so how would I perform the linecast inside of the job

[tender light]

Meaning that iteration 2 depends on the results of iteration 1?
If so than no. Multithreading is useful for independant tasks as synchronizing threads is problematic.

[compact ingot]

you need to benchmark your single and multithreaded implementation and decide which performs better, if you do not have a performance issue with it right now, its not worth it making a multihreaded variation

you do raycasts during a Job via https://docs.unity3d.com/ScriptReference/RaycastCommand.html

[minor nexus]

No sorry, as in I have 1000 instances of a class that I iterate over and in each iteration I am doing a linecast in one of those classes

[minor nexus]

Thank you

[minor nexus]

For a linecast the best solution is just raycast in the direction of the second point with length equal to the distance between the two points?

[compact ingot]

yes

well, actually no, it depends how you define a linecast

i guess a Physics.Linecast is just what you described, a ray with a length equal to the distance between the points

[minor nexus]

What other definition might there be

[compact ingot]

similar to a box/sphere/capsule cast

where you cast a line along a ray

but a linecast in that sense would be a capsule cast with radius 0

[minor nexus]

Hmm

[bold slate]

No need to rebuild the wheel. I use the free version of PandaBT and it's pretty good.

[distant pivot]

Hello everybody, I'm trying to understand something that I'm missing
So I've created some ScriptableObjects defining units in my game
1 ScriptableObject "Unit" that has 3 definitions, "Unit1", "Unit2" and "Unit3"
Unit contains stuff like a link to a prefab for the unit itself, and also a prefab for the gui object linked to it
I want to use the observer pattern, so i have an EventController that contains the delegate and a method that invokes the attached delegates
Can I use the scriptable object in the observer pattern and so, use the "Unit" representation ?
Because I want in my subscribers to use the prefabs

public class UnitEventManager : MonoBehaviour
{
    public delegate void CreateUnit<Unit>();
    public static event CreateUnit<Unit> OnCreateUnit;

    public void AddUnit(Unit unit)
    {
        OnCreateUnit?.Invoke();
    }
}

public class UnitListCanvas : MonoBehaviour
{

    private void OnEnable()
    {
        UnitEventManager.OnCreateUnit += AddUnitInfo();
    }

    private void OnDisable()
    {
        UnitEventManager.OnCreateUnit -= AddUnitInfo();
    }

    private UnitEventManager.CreateUnit<Unit> AddUnitInfo()
    {
        // How to get the unit type here so I can get the prefab ?
    }
}

[CreateAssetMenu(fileName = "New Unit", menuName = "Asset/New Unit")]
public class Unit : ScriptableObject
{
    public string unitName;
    public float speed;
    public float maxSpeed = 10f;
    public GameObject unitPrefab;
    public GameObject unitInfoPrefab;
    public CinemachineVirtualCamera unitCamera;
    public GameObject unitInfoName;

}

[gaunt spoke]

Just add a unit parameter to your delegate and pass the unit instance when invoking the event, I don't really see why your delegate has a generic parameter of type Unit too ?

[distant pivot]

I tried stuff, yeah I just found how to pass the parameter 🙂 thanks, but am I using the ScriptableObject correctly ?

[compact ingot]

there is no correct way, just ways that solve a problem and ways that create problems, you need to figure out which one you have there

[gaunt spoke]

You are, looks fine to me

[distant pivot]

Thanks guys 🙂

[distant pivot]

Still having an issue to comprehend something ..
So I'm using this to add a unit :

public class UnitEventManager : MonoBehaviour
{
    public delegate void CreateUnit(Unit unit);
    public event CreateUnit OnCreateUnit;

    public void AddUnit(Unit unit)
    {
        OnCreateUnit?.Invoke(unit);
        
    }
}```

This will be received by two objects : the unit manager, and the canvas manager
when receiving the event in my canvas manager, i need to know the reference of the gameObject created by the unit manager
is there a fancy way of doing it ?

[hallow turtle]

anyone good with photon can help me get my cameras to work

[sly grove]

isn't that what the parameter for your event is?

unit?

[heady bane]

For unity web requests is it possible to put a body in a get request?

The person making the apis made a get request that requires a body parameter to determine what to return

[fast pagoda]

usually GET requests doesnt contains a body, but you can try using the data field that is used for POST requests

[heady bane]

How do I use datafield?

[fast pagoda]

after some verification, i'm pretty sure you can't, using a GET request

but as I said, I'm pretty sure that's the API problem, not yours

[heady bane]

okay

ill talk to the person working on the api

hopefully they can adjust. the api

[undone coral]

you can use better http if you need to deal with weird stuff like this

but i am pretty sure unity web request can be finagled

[heady bane]

I cant see how though

like where I could add in a body with a get request

[heady bane]

What is better http?

[undone coral]

it's an asset store asset

you can also use httpclient on mono on PC

[heady bane]

needs to work on ios

[umbral trail]

create and attach an upload handler to the WebRequest: https://docs.unity3d.com/ScriptReference/Networking.UploadHandler.html

[heady bane]

Thank you,ill have a look intothis

[untold moth]

Anyone accustomed with the jump flooding algorithm can explain why is run in reverse order? Checking the farthest pixels first. Is it a a crucial part of the algorithm?

[leaden trellis]

Hello, I've already looked this up and cant find an answer. So in my script I have a variable
public List<turnOrder> RoundOrder;
that references inside this script

    public class turnOrder
    {
        public List<GameObject> TurnOrder = new List<GameObject>(); 

        public void addTurn(GameObject whosTurn)
        {
            TurnOrder.Add(whosTurn);
        }
    }```

At the same time I want to be able to add to the RoundOrder List by making a TurnOrder List that holds a game object so that way I can go back and keep adding to my TurnOrder lists all separately. I hope that made sense and if you need more info just ask

[untold moth]

Not sure what the question is. You should be able to access either of the lists without a problem.

[leaden trellis]

Yeah I can see them in the Inspector but I cant edit it via code. I hope this adds context

    {
        playerClone.GetComponent<Target>().unitStats.SPD_stats.current_speed = (playerClone.GetComponent<Target>().unitStats.SPD_stats.max_speed / 5) * 5;
        if (playerClone.GetComponent<Target>().unitStats.SPD_stats.current_speed < 5)
        {
            playerClone.GetComponent<Target>().unitStats.SPD_stats.current_speed = 5;
        }
        int playerTurns = playerClone.GetComponent<Target>().unitStats.SPD_stats.current_speed;
        while(playerTurns != 0)
        {
            RoundOrder.Add(new turnOrder.TurnOrder.add(playerClone));
        }

        foreach (GameObject enemy in enemyClone)
        {
            UnitEdited enemies = enemy.GetComponent<Target>().unitStats;
            enemies.SPD_stats.current_speed = (enemies.SPD_stats.max_speed / 5) * 5;
            if (enemies.SPD_stats.current_speed < 5)
            {
                enemies.SPD_stats.current_speed = 5;
            }
        }

    }```

I get this

[untold moth]

Why can't you edit it via code? Should be as simple as creating a new turn order object and adding it to the list.

Okay

[leaden trellis]

I'm not understanding what you are saying

[untold moth]

Are you sure that's the correct type?

[leaden trellis]

@untold moth as stated above It should be correct class and list inside that class

[untold moth]

It saya Battle_Script.turnOrder. Is turnOrder a nested class?

[leaden trellis]

yeah its a class inside the main script that holds RoundOrder

@untold moth does it being a nested class ruin anything?

[tough knoll]

Wow

camelCase types and PascalCase members

truly now I have seen it all
