I can't really think of much reason for someone to want to use .NET Framework these days (unless you want to use a third-party lib that depends on it). Even stuff like ZipFile are in .NET Standard these days.

[bronze lark]

Ok, this is for a WebGL build on a game jam.

[red osprey]

There's probably something I'm forgetting though.

[bronze lark]

So .Net Standard is the way to go.

[fresh salmon]

If you want broader compat, yes

[red osprey]

Unless you have a specific reason to use .NET Framework, then yeah go Standard.

[fresh salmon]

Framework is dead anyway now, they're not updating it anymore. Waiting for the big switch to .NET5 or above

[red osprey]

Yeah. Microsoft wants .NET Core everywhere, so .NET 5.0+ are all .NET Standard-based.

.NET Framework was from the time that they still wanted to leverage C# as a Windows selling feature.

It's hard to tell actual revenue of any given product because Microsoft plays the shell game with their divisions, but they're now focused hard on Azure, so .NET is focused on cloud development, which means Linux needs to be a first-class citizen, which means .NET Framework needed to get eclipsed by .NET Core.

But, even though .NET Standard is newer, it's not a 100% replacement for .NET Framework, so both hang around.

[plucky laurel]

standard actually excludes non compliant features or they are unlockable somehow?

[red osprey]

You mean in Unity? Unity maintains their own Mono runtime.

Or do you mean in, like, .NET 6 console applications?

[modest sparrow]

There's some Swift only Apple API I'd like to write a "wrapper" around, and I'm considering my options

Is the easiest route to go through the painful experience of writing C wrappers and the call into those from Unity?

[fierce surge]

Is anyone familiar with a tool for getting currency symbols for given countries based on country code?

[modest sparrow]

I've also thought about going the IPC route, maybe with something like Foundation.NotificationCenter

[red osprey]

We're doing Swift wrappers right now. ObjectiveC calls appear as

[DllImport("NameOfYourDylibWithoutTheExtension")]
private static extern returnvalue your_exact_function_name(extact_parameters parameters);
``` Note that these require restarting the editor if you change the dylib. (Once it's loaded, it stays loaded.)
You can work around this by doing dlopen and stuff... but it might be easier to just close and open the editor.

[modest sparrow]

Do you @objc your Swift files types and functions, or does Unity just eat them as is?

[red osprey]

We have an objective C header file to bridge... ... ... not sure if you can do it directly from Swift with an @objc attribute. Maybe?

All the ObjectiveC code does is maybe convert parameters and then forward into Swift.

[modest sparrow]

but this is all just functions, or can you also pass types into Unity?

[red osprey]

It's things with a C ABI... which means blittable types (ex: float[] appears as float*).

[modest sparrow]

At that point it's better for me to go the C wrapper route

thanks anyways!

[red osprey]

Objective C wrapper is basically a C wrapper, yes.

The benefit comes from forwarding those C calls to... ... ... a not-C language lol.

Personally, I'm a fan of C++, but that might not be ideal, especially if you're interfacing with Cocoa or something.

[modest sparrow]

I mean fair

[modest sparrow]

It's that Apple hasn't exposed GroupActivities API to anything but Swift:
https://developer.apple.com/documentation/groupactivities

[red osprey]

I should note that I'm not tooooooo into macOS stuff. Only picked up the platform when I joined LightTwist a couple months ago.

Before that, I've never owned a Mac.

[modest sparrow]

So I'll have to write a lot of wrappers around this XD

[red osprey]

Yeah...

Probably best to boil down what you need to a handful of C function calls, and, using swift on the other side of those C calls, expand into the actual stuff.

Add as you implement more stuff that needs to talk to Unity.

Hopefully the initial isn't too bad.

[modest sparrow]

I'll just use this for the type, and then write as C-like API as I can, and then wrap that in as C# like API as I can on the other end:
https://developer.apple.com/documentation/swift/opaquepointer/

and then use... protobuffer for like more extreme types

[red osprey]

That's one option. We haven't gone to this length yet, but we were planning on sending JSON and/or Protobuf across our C API.

Gets more complicated because the other end of the C API is mach_ports into a completely different process.

[modest sparrow]

Scott since we think so alike, can you hire me :P

[modest sparrow]

makes it perfect to just use protouf!!

[red osprey]

I tend to get scared when heavy dependencies are added... although the other devs are happy with it.

[modest sparrow]

I just thought about it, maybe I can just use protobuf Unity <-> Unity, and have the Data / unsigned short[] passed through the bindings

[red osprey]

Yup. Just make sure it's clear who owns what.

But, for the duration of a function call, that's not too bad.

[modest sparrow]

because there's no reason really to decode the handle the date outside of Unity

I'm curious what you're using mach_ports for in a Unity project, but that's really not my concern

[red osprey]

I can't really comment either way I really have no idea what you're actually doing lol.

We're communicating with a Cocoa application.

[modest sparrow]

I'm planning to write a Unity wrapper for SharePlay

[red osprey]

It might be a little more low-level than necessary, but it's an architecture that works.

[modest sparrow]

SharePlay is almost as high level as they get XD

[arctic robin]

Hi!
What is the correct component to use when spawning a dynamic amount of buttons on an axis? (1-10)

[quartz stratus]

You probably need to write a custom component. You want a class with a public endpoint that receives an integer, then creates that many button objects? You can couple it with a LayoutGroup and LayoutElements to have them automatically spaced/positioned/sized in an area of your choosing. Is that what you're going for?

[arctic robin]

That sounds correct. At the moment I'm testing it with GridObjectCollection, instantiating prefabs and then updating the collection.

[arctic robin]

But I would love if I could test the instantiating part inside the prefab editor.

[quartz stratus]

That would indeed be helpful. I simulate this by entering the prefab editor via a prefab instance in my scene, placed where it will actually be, then Unity at least retains the layout and graphical appearance of the rest of the scene while I edit. Then I can drag and drop my button prefabs inside to make sure they are correctly positioned.

[arctic robin]

I want to have a function where the number of buttons corresponds to the number of files an Assets folder. What do I expose in the inspector, and any tips on turning audio files over to audio clips?

[quartz stratus]

For counting files, use https://docs.microsoft.com/en-us/dotnet/api/system.io.directory.getfiles?view=net-6.0. Then you can iterate over them and check their extension if you want.

[quartz stratus]

For converting audio files to audio clips, use https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequestMultimedia.GetAudioClip.html

[arctic robin]

I'm essentially loading short audio clips to work in a sequencer, should I structure that around StreamingAssets or Resources?

Re: WebRequest

[quartz stratus]

Ahh I see. Sorry, I'm not sure on that one. Scratch what I said about GetAudioClip, there's probably a better way to do that with a tool like one of the ones you mentioned

[arctic robin]

I've cooked something up, 2 sec

[quartz stratus]

Nice, looks good. Small optimization: change the type of rowPrefab to Sequencer, then re-assign in the inspector. Then you can spare the GetComponent call.

[arctic robin]

Oh, does it only return a component from the instatiated object then?

[quartz stratus]

Yes, Instantiate will return an instance clone of the same type of its first parameter

So it will hand you a Sequencer instance ready to use

[arctic robin]

But rowPrefab is a prefab, and Sequencer is a component. Tried what you said but didn't work.

Oh wait

[quartz stratus]

rowPrefab happens to be made into a prefab but it is of type Sequencer, just as it is of type AudioSource, Transform, GridObjectCollection, etc. It is of the type of all components you assign.

Part of unity's somewhat confusing component oriented structure

Did you get it working?

[arctic robin]

Testing

and Unity crashed lol

But it is set up like this atm

[quartz stratus]

The crash is probably unrelated to switching rowPrefab to Sequencer type

As long as the Sequencer component is assigned to your rowPrefab GameObject and you've assigned the prefab to your rowPrefab field on whatever class that is, that should be good to go.

[arctic robin]

Wait is there no autosaving in Unity?

[austere jewel]

Scenes are backed up during a crash but are wiped as soon as you reopen Unity

You should be using a form of source control regardless

[arctic robin]

I did, until Unity tanked my Teams pipeline and I can't get Plastic to work properly

Stuck on the good ol'

[Collab] Archive::ArchiveError: Unable to perform requested action on a project that has been archived. To unarchive this project, navigate to the Developer Dashboard at http://developer.cloud.unity3d.com and click View Archived Projects. Select the 'Unarchive' button to restore the desired project.

on an un-archived project

[hushed fable]

How about good ol git hosted on GitHub? 😄

How did Unity manage to break your previous version control solution? Not exactly sure what Teams pipeline refers to, but I'm assuming Azure DevOps?

[arctic robin]

Used Unity Teams to transfer between 2 PCs, suddenly it broke at the start of January. Refuses to sync.

[hushed fable]

You most likely won't suffer from these magical errors with external source control solutions

[arctic robin]

True

Think I gotta go there

Furthermore, I need to instantiate a button that then needs to be linked to the object that instantiated it, responding to clicks of the button. Do I need to do a "when pressed: transform.parent.something" or is there another way?

Need to create this event at runtime

[undone coral]

you have to write a plugin. you can buy a prime31 plugin and see how they organized theirs

[austere jewel]

I'm making a motion capture app and seeing "prime31" really confused me for a bit there

(https://optitrack.com/cameras/primex-41/)

[undone coral]

you have to report this bug to unity

[arctic robin]

What are the differences between these two?

[undone coral]

nothing that really matters

[quartz stratus]

One pretty straightforward solution: have your controller class pass your button instances one of its methods in the form of a UnityAction<int> or <float> (whatever that value type is) in a public initialization method after they're instantiated. Have them cache the UnityAction, then invoke it when they're clicked, passing whatever value they need to back to the instantiating controller class

[undone coral]

it sounds like you need to use unirx @arctic robin

if you want to do complex stuff iwth events

[arctic robin]

I think(?) I tried a version of this, but it somehow just ends up sending 5.

[undone coral]

you don't quite yet

[arctic robin]

        for(int i = 0; i < buttonAmount; i++)
        {
            GameObject button = Instantiate(buttonPrefab, new Vector3(0, 0, 0), Quaternion.identity, this.transform);
            //button.GetComponent<Interactable>().OnClick.AddListener(() => RadioClick(i));
            button.GetComponent<Interactable>().OnClick.AddListener(delegate { RadioClick(i); });
        }

[austere jewel]

Due to the complexities of variable capturing (closures) when using a delegate inside of a for loop you need to assign the indexer to a local variable before using that in the delegate

for(int i = 0; i < buttonAmount; i++)
{
    int localIndex = i;
    GameObject button = Instantiate(buttonPrefab, new Vector3(0, 0, 0), Quaternion.identity, this.transform);
    button.GetComponent<Interactable>().OnClick.AddListener(delegate { RadioClick(localIndex); });
}```

[quartz stratus]

Never knew why that technique wouldn't work for me before, ty

[arctic robin]

Awesome, that worked perfectly ❤️

Is there any way to keep certain components from spawning before others are loaded?

[hushed fable]

What issue are you trying to solve?

[arctic robin]

I'm using another library, and it's designed to instantiate parameters in the inspectors before runtime. I'm however creating the variables during runtime, resulting in it complaining that certain fields are empty.
At the moment, all my functions are using Start() as opposed to OnAwake(). Could this be a potential solve?

Furthermore, Unity is taking a solid 10 seconds to unload after I stop playing. Any common reasons for that?

[arctic robin]

Specifically, this line of code.

[short junco]

Time.UnscaledDeltaTime ignores the time scale right ? I want to create a slow down up mechanic for spesific objects only but doc says unscaled its best fit for that its ignores the time scale but when i change time scale unscaled delta time values are changeing how can it possiable ?

[hushed fable]

Yea you could set it up in Awake. These things are pretty situational. If the library component is on a different GO, you could try instantiating it later

There's also DefaultExecutionOrder attribute if you can't find other ways

[arctic robin]

Got it, noted.

At the moment I'm having trouble spawning a prefab correctly lol

I keep getting this error from this code:

SequencerDriver childDriver = Instantiate(blockman, new Vector3(0, 0, 0.5f), Quaternion.identity, this.transform);
        RowsConstructor asd = childDriver.GetComponent<RowsConstructor>();
        Debug.Log(Sound.Bass);
        switch ((Sound) sound)
        {
            case Sound.Bass:
                //asd.sound = Sound.Bass;
                asd.SpawnMe(Sound.Bass);
                break;
            case Sound.Lead:
                //asd.sound = Sound.Lead;
                asd.SpawnMe(Sound.Lead);
                break;

        }

Does GetComponent not work if it's not a GameObject?

[austere jewel]

https://help.vertx.xyz/programming/common-errors/runtime-exceptions/nullreferenceexception

[arctic robin]

This could easily be solved with a prefab variant, but from what I can tell, the variant doesn't derive any further changes to the original prefab, like position, size etc.

[zenith hedge]

Question, haven't really worked in Unity for over a year but more with C# itself. Now I'm back trying to make a nice game. Now I want to create one SceneManager which holds all the code to use on buttons inbetween scenes. Now what would be the best way to assign the OnClick functions using this SceneManager object as DontDestoryOnLoad()?

[obsidian citrus]

Hi, I need little bit help related to jsonUtility;
I want to store Dictionary in json format, eg Dictionary<float,customClass> foo

[sly grove]

It's not directly supported. Use Newtonsoft JSON or look up unity serializable dictionary

[raw schooner]

why not suggest System.Text.Json?

[quartz stratus]

Newtonsoft is much more robust and free, there's almost no reason not to use it afaik. It gracefully handles nested object serialization, custom converters, OnSerialized/OnDeserialized callbacks, and more

At the same time, if you only need light JSON functionality, System.Text.Json is perfectly fine and saves you a package import.

[raw schooner]

true and fair

[hot tendon]

hey is there a way to render a mesh without indices in unity?

[plucky laurel]

we dont have that in unity i thought

[quartz stratus]

Oh you're super right, you'd have to add the System.Text.Json dll if you wanted to use it. I thought they were referring to unity's JsonUtility, my mistake

[sage radish]

Graphics.DrawProcedural should be capable of that.

[fresh basalt]

Anyone familiar with nativegallery?

[real plume]

anyone here familiar with MLAgents? I'm getting basic code throwing an error(in editor, won't compile) that's basically a copypaste from documentation, and I can't seem to figure out why. been stuck for 2 days...

[jaunty temple]

Try asking in #archived-machine-learning also?

[vestal quarry]

Anyone know how to read input while the window is unfocused I'm trying to use ovr and send an input when the home button is pressed.

[mighty cliff]

Hey guys, im getting an invalid typecast here when i try to downcast to an inherited member. How to fix?

nvm just used as Type instead of (Type)

[gray pulsar]

fyi I think the is operator is a better fit for what you're doing. I'm assuming HeroExtension and EnemyExtension are mutually exclusive
https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/operators/type-testing-and-cast#is-operator

if(target is HeroExtension a)
{
  // Do hero relevant checks here
}
else if(target is EnemyExtension b)
{
  // do enemy relevant checks here
}

[austere jewel]

You can also do similar in a switch statement

[regal olive]

Not only do I want to implement acceleration gradually rather than instantly, but I also want to implement slope physics to add on to that.

Is there any references that can help?

[manic wharf]

why does my projectile bullet can moving through walls with continuous collision detection?

[mighty cliff]

May be going too fast for the collision to keep up. Use a Raycast to check coillision instead

Like for the update frame, raycast from the previous position last frame to its current position, and if something is in the way, consider it collided

[manic wharf]

really! i'm an idiot)
Thanks a lot

[compact ingot]

You'd first build a really efficient spatial lookup datastructure then implement your collider shapes in a nice and computationally optimal way, then come up with some collision detection mechanism based on shapes and the spatial lookup, then you'd implement a collision resolver that can separate overlapping shapes, maybe add some simulation of mass, drag, friction etc and then you run that 50 times per second, cry for a bit as your performance goes to the toilet and then start spending the rest of your near-to-midterm future getting it closer to where PhysX, Havok and other systems already are. Eventually you'll need a neat API for it all and you'll implement raycasts, rigidbodys, colliders and more specialized versions of those.

maybe you should come up with that yourself then if its for a work test

not gonna help you cheat

[quartz stratus]

plz tell me you're interviewing for a job doing nasa simulations or something. this is giving me a headache just thinking about it lol

[undone coral]

what would be the purpose of that?

[flint sage]

Not really no

[flint sage]

You can publish the source without publishing the assets (that you are not allowed to redistribute)

I think a private repo that you include using submodules/subtree is the easiest

[undone coral]

oh... yeah that's a dead end

[lost dove]

I have this code for "flashing" the Windows process icon on the task bar

static extern int FlashWindow(IntPtr hWnd, bool invert);``` Which works on WinForms when using ``Control.Handle`` (IntPtr) but it does not work when I try supplying ``Process.GetCurrentProcess().MainWindowHandle`` or ``Process.GetCurrentProcess().Handle`` Can anyone help me here? I want to be able to flash the process task bar icon on command

I want to flash my Unity game process icon in the Windows task bar for instance when a multiplayer game is found and Application.isFocused = false so that the user will know when they've joined a game

I'm not sure how to get the proper handle to supply to the user32 FlashWindow method, because clearly Process.GetCurrentProcess() isn't working

[deep scaffold]

Async methods continue to execute when you stop the game in the editor, what the best way to stop if from happening

worst part is prefab clones are staying in the scene even play mode is off

[clear plover]

Hello everyone. It is unlikely that anyone here will help solve my problem, but maybe they will be able to suggest some idea or rethink the existing one. I'm doing a Bullet Hell, that is, I want everything to be normal even with a few thousand bullets, so I gave up GO in them for a long time (except for visualization, but this is not particularly important yet) and I seem to be satisfied with performance, but I understand that I don't even check collisions yet and always need more, especially for mobile phones. That is, I decided to rewrite everything to Jobs (I will immediately answer that I don't want to switch to a full-fledged ECS, because I want to solve the problem somehow without it (since I've been suffering for so long, heh), and then only bullets will then work on it, because I want to write the rest on OOP). In general, I mean that so far I'm collecting the behavior of bullets like this ( https://cdn.discordapp.com/attachments/910812777709441025/910896056554905650/2021-11-18_17-11-49.mp4 (the old video, but not the point is important)) and these elections, factories with a date field were created, which are structures, and there the logic of the motion component was already called on polymorphism. What happens is that I don't need factories and components with logic anymore, so I decided to take IJobParallelFor and write "systems" and that's where the main problem begins. I also have general bullet data (by type of position, rotation, size, etc.), and there are dates specific to a certain movement system. And the whole problem is that how to transmit to all systems only the positions (or other general data) of the bullet she needs now? Otherwise, I simply will not be able to start all the motion systems at once, since they will use the same NativeArray, thereby jobs system simply will not be able to understand that I am not violating the race condition, although I know that I will definitely not violate it. And in general, so far I have only a few ideas:

1. Store NativeArray in a certain "updater" that simply launches the desired system and stores an array of indexes (NativeArray<int>) from the general data. But then, again, all movement jobs will be waiting for each other, and not immediately distributed in a reasonable way. And then the additional taking of indexes, although it probably still turns out to be productive for the ideas given below, except when the latter;
2. Store everything as above, but make copies using for (well, you can do it through UnsafeUtility, but for you need) to prepare a NativeArray for the current frame. Then I'm sure with a high probability that everything will be distributed correctly, but then it's just a bunch of copying, which I think is terrible, since I'll have to copy everything back after work.
3. Remember the ECS Unity and think about their ideas of archetypes and chunks. That is, my idea is to store them in a row in one array for each group of systems (motion systems, systems etc.), and then create slices (subarrays) of these errors. That is, I will be able to achieve confidence that everything will be disassembled at the same time, but I will still have to copy the general structure, because they can still change in theory in another group of systems (for example, a magnetic bullet or, when destroyed, a bomb will create a shock wave that will scatter bullets around). But this is definitely a productive second method, although maybe if someone knows how Foreach or a filter works in Unity ECS, well, or in another ECS (that is, it finds only entities with the necessary components (although, to be honest, I can guess how to do it myself, the only question is how to put it all into native collection and productively parallelize))...;

4. I'm forget that have been suffering for so long and do it normally on ECS Unity (but don't switch to drawing using DOTS, but use it only purely to calculate data), but then it will probably be less manageable. Well, in terms of what, where and in what order to call.

[austere jewel]

Cancel them with cancellation tokens

[deep scaffold]

Thank you kind sir/madam

[strange condor]

Might be overkill but I created 2 separate classes to do so:

And you can see i have a static CancellationTokens that deactivate on scene change or when the game stops

[deep scaffold]

this is some good 💩 , gonna have much fun by discerning it

[lost dove]

Good stuff, but I can't help myself, I suggest looking into the recommended IDisposable pattern to help with the terrible GC

[strange condor]

What do you mean, I'm using the IDisposeable.
What do you suggest I should change?

[lost dove]

https://docs.microsoft.com/en-us/dotnet/standard/garbage-collection/implementing-dispose

[strange condor]

Thought maybe that will be useful as well (I tried imitating all features of courotines, like the way they stop when the object is disabled or destroyed):

[lost dove]

Most of the time you don't really need to worry about your code performance, until you do

GC is one of the most heavy operations in the CLR

But then again, its until you do need to worry about it

[lost dove]

Just to be clear, your code isn't terrible... I meant the runtime CLR garbage collector is terrible 😛

Your code is actually pretty good, it's just that it's not completely conformant. I'm really just nitpicking

I have a very similar implementation in Xamarin, it should work nicely

[strange condor]

I want all the nitpicking you can give me! 🙂

This code is battle tested, but I admit I usually don't mess with the GC operations at all, good chance that it's a place for improvements.
Any way, thank you.

[lost dove]

If you're using the Mono backend, then you can already assume the GC is terrible

Which is why you want to enforce suppression on finalizers if the object has already been manually disposed

[strange condor]

Ok, I'll read the link you sent me.

[lost dove]

https://docs.microsoft.com/en-us/dotnet/standard/garbage-collection/fundamentals

Just keep in mind, GC isn't the save and grace for your code. It's just a massive thing to keep in mind

[odd grove]

Hi. I am creating Animation component upon gameobject using script. When I set parameter using SetFloat and return it back, it returns 0. Is there something I miss? For example setting of new runtimeAnimationController or something?

I've tried bodyPartAnimator.runtimeAnimatorController = new AnimatorOverrideController();

but without luck. I am getting this message back "Animator is not playing an AnimatorController".

[lost dove]

Just from what I've seen in Unity, GC takes A LOT of time, especially compared to other components

[obsidian citrus]

I tired to implement,

demo = new Dictionary<float, Vector3>();
Debug.Log(JsonConvert.SerializeObject(demo));

JsonSerializationException: Self referencing loop detected for property <- error i got

works fine with normal datatype but vector3 seems like unsupportable.

[meager remnant]

maybe since the Vector3 is a unity type?

idk I don't know much about serialization

you could make your own Vector3 though by just having 3 floats x, y, z

[obsidian citrus]

yeah, its working with normal float x,y! 👍

[glacial wedge]

is a scene gameobject InstanceId a good way to save reference in ScriptableObject?

[hushed fable]

Afaik there are no stable IDs in builds. What are you trying to do?

[glacial wedge]

to save the ID of specific Scene Component in scriptableobject used as state for my statemachine

[hushed fable]

Unity employee couldn't save references across scenes without creating a separate ID system. https://github.com/Unity-Technologies/guid-based-reference/

[glacial wedge]

not across scene

it's just for one scene

[hushed fable]

Well the across scenes part isn't too important, since I still don't think there are any stable IDs left in the build.

[glacial wedge]

maybe this is works?

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

[sage radish]

That's editor only unfortunately.

[regal olive]

https://www.toptal.com/developers/hastebin/olalucoqos.csharp
I'm using this piece of code to generate platforms which guide a ball towards a goal (trick shot style) using PhysicsScene.Simulate.

The code works perfectly when the validation logic is not triggered, and GeneratePlatforms runs only once.

The trouble is whenever the validation logic is triggered, something often goes wrong with the path generated: platforms in the beginning or middle don't appear, causing the real ball (since the path is traced by a "fake" ball) to not follow the generated trajectory.

I need permission to provide the full source code but I can help set up a basic project to reproduce the issues.

[glacial wedge]

fuck!

my entire StateMachine doesn't work in build

it seems that the Machine doesn't read the ScriptableObject of the transitions

[glacial wedge]

it lose the dictionary values in build with IL2CPP

You sure private repos break the terms?

Asking for a friend

[alpine adder]

hey is it ok to throw exceptions in unity? or is it prefered to return null. curious if exception throwing crashes the app

[compact ingot]

exceptions are caught by the engine and will be converted into an error-log message

[alpine adder]

Awesome so it wont crash the app 😄

Thank you

[flint sage]

If that's the terms of service then every large company is breaking them including unity

[alpine adder]

any ideas what these files could be? never seen them before and now they are just added randomly. I did recently switch from visual studio to rider to try it out

[fresh salmon]

Yeah that's rider metadata

[alpine adder]

awesome thank you

[undone coral]

i see. yes, unfortunately private submodules are your best bet

if you'd like to minimize the number of private submodules you have, you can create a private unity package repo, and install your asset store assets there

and just reference that 1 package

hope that helps

[undone coral]

yes in my experience you can add .idea/ to .gitignore

oh

you can definitely commit assets to a private repo

are you saying you want to put this in a public repo?

[steady latch]

How to round 0.9999 to 0.9 ?

[fresh salmon]

• 10, floor, / 10

0.9999 * 10 == 9.999
Mathf.Floor(9.999) == 9
9 / 10 == 0.9

Just make sure they're floats all the way, otherwise you'll stumble upon integer division

[steady latch]

so what? now im confused maybe i should i writed in beginner or general x)

if its 0.99999 its a floats and i want the numbers to be 0.9, i did try ToString("0") but dident work

[fresh salmon]

Oh you just want to format the float so it appears with one decimal? You should have said that

theFloat.ToString("1F");

Will work fine

Or "1F", if that doesn't work

Yeah it's "F1"

Note that will round the number, so in your case it'll display 1.0

[thin mesa]

If you are using an interpolated string you could do {theFloat:#.#} to format it to one decimal place without rounding

[steady latch]

nah i want 0.9999 to be 0.9

not whole

[fresh salmon]

That rounds too unfortunately

[thin mesa]

Does it really? 🤔 I guess I misread the info

[fresh salmon]

So without rounding, apply the multiplication, flooring, and division method

[steady latch]

haha what?

[fresh salmon]

This

Yeah you really shouldn't have posted here frankly

It's a formula, some pseudo-code

[steady latch]

ye sry next time ^^

yeah dident work gives errors dident understand anyway

[fresh salmon]

To truncate a number to one decimal you need to:

• Multiply it by 10
• Floor the result
• Divide the result by 10

[steady latch]

oh ye

math is not my best side

but i understand what u mean

[fresh salmon]

And avoid cross-posting.

[steady latch]

yeah but u gave harder answer so i asked somewhere else lol

[fresh salmon]

It's #archived-code-advanced after all, expect advanced grade answers. Cross-posting is against the rules

So if you post and get answered in one channel, stick to it

[regal olive]

hey how do i use assembly in unity

I'm bored of following C sharp's rule

I want to make my own rules

fr

anynoe

[fresh salmon]

You can't

[regal olive]

why

Unity is big huge everything is possible

[fresh salmon]

Because Unity is backed up by a closed source C++ back-end, and you would need to modify that to integrate another language support

And since you don't have access to that ¯_(ツ)_/¯

[regal olive]

ammm

[austere jewel]

You can make native plugins. It's an easy enough Google. But the question itself is disingenuous spam that would be better off not being asked at all

[fresh salmon]

Yeah this, if you want to code in asm, find a game engine that supports it

[regal olive]

how did u guys learn unity

[fresh salmon]

Or make your own

[regal olive]

engine

[fresh salmon]

Yeah, in asm

Good luck with that

[austere jewel]

This isn't a question for #archived-code-advanced , go back to #💻┃unity-talk and don't spam random questions across the discord

[fresh salmon]

Ah, yes. They want to code in asm because they don't understand the C# beginner tutorials. Great

[regal olive]

are u mod?

[fresh salmon]

100% troll

[regal olive]

Octagon?

[fresh salmon]

It means "stop"

[regal olive]

🛑

[fresh salmon]

And yes, they're a mod. It literally says that if you click on their profile

[regal olive]

I don't believe my eyes

[fresh salmon]

It's not gonna end well for you mate

[regal olive]

help?

[fresh salmon]

Ask in #🌐┃web

[austere jewel]

Don't ping people into random questions either.

[pliant nest]

Hello can someone point me to a tutorial on implementing a placement system which allows dragging objects from inventory into the world, in first person. thanks 🙂

Thank you I will check it out!

[undone coral]

are there examples of project tiny projects that use nicer, baked, non lo-fi rendering? is this possible to engineer with project tiny at all?

okay

i see that project tiny has been graveyarded

my sincerest apologies

[warped kettle]

Wait it has?

[undone coral]

i don't think there's anyone working on it at unity anymore

[plucky laurel]

it kinda flashed briefly, then sank.

[warped kettle]

"[0.32.0] - 2020-11-13"

Is there a unitygraveyard.com like googlegraveyard?

whoops, killed by unity*

[plucky laurel]

yes Unity Engine

a collection of half finished libraries we call engine

[warped kettle]

I need a mod here. Someone just murdered someone.

[undone coral]

lol

[warped kettle]

Yep.

Imagine to my surprise that using the new input system, it doesn't work on linux (I think it was linux?)

Tho I think they added linux support finally to it

[glass anvil]

Odd question to ask in #archived-code-advanced

#🌐┃web

[ocean raptor]

It used to be so simple..

Then they started trying to pander to everyone..

Render pipelines.. package manager.. is this feature in the version I'm currently using? GitHub? Why is it on GitHub? Oh alright.

Also, let's rip out the networking layer before we have a replacement ready to even beta, let's see how that goes

[dawn zinc]

Any external hardware you guys bought that help you program?
Maybe a certain kind of monitor, usb hub, just stuff to make your job easier or enhance it

Just got a USB hub and quite frankly it's amazing

[sharp totem]

is there any tutorial for random block generation pros

[undone coral]

depends how pro.

you can look into Daniel Ritchie who authors the most approachable language and tutorial for probabilistic programming in procedural graphics

which is like an Intro to Pixar Stuff

not unity specific though

[flint zinc]

Hello everyone. I had an issue where I had an instance running for the game and I wanted to avoid a second instance for the game to run. I solved this by using the PlayerSettings.forceSingleInstance setting. Now I had a question, what if I wanted the second instance to fire a method on the first instance before it quits.
A couple of things come to my mind but I'm all open for options. First one was to have the script that would be used to fire the method at the top of the script execution order. And then I'm unsure of the part that comes after. How do I fire the method on that game instance? How do I find it? And after finding it, how do I execute a method on there preferably with parameters?
Using PlayerPrefs was one of the things I came across but I wanted more opinions on this.

[somber tendon]

maybe using getprocessbyname, at least if it's running on desktop windows?
https://docs.microsoft.com/en-us/dotnet/api/system.diagnostics.process.getprocessesbyname?view=net-5.0

And after that maybe firing the method using Process.Start()

[tough tulip]

Process and its namespace (partially) is not available in windows il2cpp

[tough tulip]

i would suggest you to use sockets. Sockets work on literally all platforms unity supports.
In your application, try to connect to local port on some port, say 1234.
When the connection is refused, create a new port and listen to that. Add a try/catch over the bind logic to maintain concurrency incase both applications are launched at almost the same time.

Then when your 2nd process sees that it can connect to that port 1234, just shoot your message over to the first process and then close the 2nd instance manually using Application.Quit

[flint zinc]

So I tried to search a bit and found pipes, specifically named pipes.

Would that be a bad implemetation?

Again I'm not sure about the compatibility of it but since it's C# I assume it would work well with other platforms.

[flint zinc]

Yea, I saw that and in my previous experiences it's been very un-reliable. Especially when dealing with different platforms.

[regal olive]

anyone?

[tough tulip]

named pipes is a part of ipc which is provided by Windows Communication Foundation (WCF).
I have never tried that in unity or anywhere outside of windows.
You can still implement the piping in c++ for all the platforms yourself if thats what you're looking for

[flint zinc]

I've actually just seen a video for it and I was planning on building that function as a separate DLL and importing it into unity as a plugin.

In the video tho, it was explained that the implementation for it work well on editor but fails on 64 bit versions.

And so would have to be build on 32 bit, so just lost there as well.

[tough tulip]

editor is 64bit backed by mono.
you should have no issues in making 64bit mono builds

[flint zinc]

Also the reason I was avoiding sockets is due to security reasons. Since I'm not very good at security related to sockets in general.

[flint zinc]

Ah okay. I wonder then if the person was using IL2CPP.

Since that's what I'm using.

[tough tulip]

if you are avoiding sockets, try MemoryMapped files in System.IO?
it should be there in Unity although i can't verify if that works

[flint zinc]

MemoryMapped. I can try googling it lol

[flint zinc]

Thanks for the help. I've got named pipes implemented in a test app for now, gonna build it soon and will share my findings here.

If it build or fails etc.

[glacial wedge]

i need help for exposed reference

I found this video that make it works

https://www.youtube.com/watch?v=KFFCGABCH3c&ab_channel=alexwinx

but I can't reach to achieve the same result

[terse rampart]

is there a way so that when I respawn, the button I'm clicking will be deselected?

[tough tulip]

EventSystem.current.SetSelectedGameObject(null);

[terse rampart]

it doesn't seem to work tho

[tough tulip]

youre never releasing your mouse?

[terse rampart]

yeah

it's for the ebrake

i have it set to toggle on and off

but when I respawn, I want it default to off

even tho i respawned with it on

[tough tulip]

well in that case, use images with IPointerUpHandler and IPointerDownHandler
when you press, IPointerDownHandler is used. toggle isPressed bool to true and start accelerating.
when you die, just turn it to false. so it will have to be true again only when the user leaves and presses mouse again

[terse rampart]

I am using IPointerDownHandler

[tough tulip]

then use the rest

[terse rampart]

explain please

[tough tulip]

I already did. I dont know how to explain more than this. If you're new to unity, you would have better luck in #💻┃code-beginner or #archived-code-general

[sage radish]

Are you referring to section 3.8 here?
https://unity3d.com/legal/as_terms

[undone coral]

then yes, i'd use a submodule or a package referencing a private repo

containing the asset store assets

that will satisfy the terms

[undone coral]

what's the objective?

processes communicating with each other is always painful

names pipes are really painful

the security of a named pipe and a socket bound to 127.0.0.1 are basically the same

there isn't a real scenario where listening on 127.0.0.1 exposes you to a security issue

so i'd suggest just using a udp socket listener on that address.

that said you can only have exclusive use of a port. very painful

[flint zinc]

The objective is the use custom URL schemes and launch the app. That part is simple. But to do so if the app is already running and have only one instance while having the arguments passed through. The reason I'm avoiding sockets is that the arguments might or might not contain some stuff which I wouldn't want someone to catch in the middle.

[undone coral]

you mean for the purposes of implementing a login?

[flint zinc]

Sort of yes.

[undone coral]

for like a lobby code?

like multiplayer?

[flint zinc]

Yea

Room data etc.

[undone coral]

or for a chat room id?

is this a chat app?

[flint zinc]

Nope

[undone coral]

okay

[flint zinc]

So what are you opinions? Would really like to know.

[undone coral]

i don't think there's a threat where listening on 127.0.0.1 opens you to a security issue

i don't know how detailed you want me to go into convincing you

[flint zinc]

So me opening a port locally. That's good. Someone with wireshark or something similar might simply see that the port is opened by the application, and not to mention able to sniff the packet. That's my concern here.

[undone coral]

someone meaning who?

the local user?

[flint zinc]

Yes.

Since the implementation would be on the client side.

[undone coral]

what scenario is it that a local user

who is seeing the deeplink url

would be now untrusted?

why would there be anything important about this packet?

you could just forward the exact deeplink url they clicked

surely that's not private?

so you can... start your second instance on a clickthrough of a deeplink url, and then message the deeplink URL over the socket to the first instance

there. nothing "proprietary" is shared

a named pipe, which maybe just obscures this stuff, isn't any more secure. but in reality, exactly zero people on earth will ever be bothering with this

[flint zinc]

The thing is, when using something like OAuth (just for example), you login on a web interface. You put in your credentials and then you get a token which is then passed onto the application. IF in case the API end points are compromised by any number of methods be it de-compiling or anything, the said person would have access to update the data. Not saying we couldn't flag it, but just trying to make it harder for people.

[undone coral]

okay... but you're not implementing oauth correctly

[flint zinc]

I did say it's an example lol

[undone coral]

so what are we talking about? is oauth the goal?

what do you mean the API end points are compromised?

then they're compromised. i suppose the threat actor could do anything

they probably have access to the database if the API is compromised

so it really depends on much detail you wanna go into this

[flint zinc]

They could only do it if they've got the correct clearance, in this case the correct tokens.

[undone coral]

anyway, the end user already sees the deeplink url

[flint zinc]

I mean, I'd like to know your point of view, in a constructive manner ofcourse.

[undone coral]

yeah

well the most straightforward answer is that no one is going to compromise anything, you're too small beans

but even in this conception, if you can't trust the user's machine, this is impossible

[flint zinc]

Alright.

[undone coral]

zoom doesn't do anything special. it is just a deeplink with this meeting code id

once it hits a local zoom app, it doesn't really matter how they implement the details

it's not any more or less secure

depending on how they deal with this Windows UWP thing

which by the way, i'm surprised it starts 2 instances in UWP

on iOS it does not

[flint zinc]

So just going back a bit, named pipes do obfuscate a bit right? We're not trying to make it impossible. No we don't do that for someone snooping around. It's just that we could make it harder.

[undone coral]

i think listening on a local port is pretty obscure

i don't understnad though... why would someone bother snooping on the port

they could just snoop the browser?

if they have access to the local user's machine

like why bother

it just doesn't make sense

are you trying to protect from the user? the deeplink URL they clicked on?

[flint zinc]

They don't click on the deeplink.

[undone coral]

it doesn't make any sense to run an RPC API over a named pipe

[flint zinc]

Ugh

[undone coral]

what do you mean?

"The objective is the use custom URL schemes and launch the app. "

[flint zinc]

Have you seen how unity does the authentication?

[undone coral]

are you making an authentication app or a lobby code?

are you trying to do oauth?

what are you really trying to do?

[flint zinc]

I'm unsure if this is productive anymore.

[undone coral]

i just read your question over and over again and it sounds like you want to use custom url schemes

[flint zinc]

But yes. It's an oauth process.

[undone coral]

well...

do you want to do oauth correctly or not?

[flint zinc]

Yes but I wouldn't be using deeplinks directly.

[undone coral]

"how unity does the authentication?" do you mean an official Unity.. authentication library?

[flint zinc]

The official unity.

[undone coral]

can you link it to me?

[flint zinc]

You can try to login to your unity account using the editor.

[undone coral]

yes

okay...

[flint zinc]

Dude, it's not inscribed anywhere lol

[undone coral]

it's okay

[flint zinc]

It's the usual oauth2.0 and then loopback url to the unity hub app

[undone coral]

so is your objective to implement oauth2 login for a unity app?

and it sounds like you're working around some peculiar issue?

and you're thinking of using a custom scheme as a redirect URI?

[flint zinc]

Yes.

[undone coral]

okay

so why didn't you say so 🙂 ?

i don't think a named pipe will matter here

anything can snoop on a native app's token that it gets from oauth2 flows

[flint zinc]

Just that the actual function is similar but still different. Hard to explain but yes the use case is the same.

[undone coral]

hmm...

[flint zinc]

Yea

[undone coral]

so it is invite codes for a chat room?

so then it's a moot point

[flint zinc]

I know we can't make it impossible.

[undone coral]

it isn't ever going to be obscured

[flint zinc]

But we can make it harder.

[undone coral]

it's a colossal waste of your time to try to obscure it

nah

i mean you can say that in sort of a fantastical way

but all you're doing is making it harder for you to program

[flint zinc]

Nah lol. If it was just that I wouldn't bother

But it's gonna be a bit of sensitive data. And I know the "small beans" thing, but please humour me.

[undone coral]

is it a crypto related thing?

[flint zinc]

Nope

[undone coral]

then what is it

[flint zinc]

It is a login. Yes. But mixed with a few more things. I wouldn't be comfortable discussing the workings of what goes into it.

[undone coral]

okay

well i think you'llf igure it out 🙂

[flint zinc]

Thanks for all your help!

[undone coral]

generally, i think if you want to do login, you should use a library that implements OIDC and an approach that gives you session tokens

any data that isn't login related... you can just provide via a secured endpoint

you can use OIDC and get bearer tokens

i think there are always a lot of misunderstands about what these different standards do. OAuth for example is really just designed to protect from harvesting your Facebook or Google password

people shove the token they get into databases, cookies, all sorts of stuff that exposes the token to adversaries, and Oauth never specified what to do with the token because it doesn't really care

it's a crappy and incomplete standard

OIDC says pretty clearly you put bearer tokens in LocalStorage

[flint zinc]

Your opinions on other standards?

[undone coral]

session tokens can go into cookies

for native applications they have stuff

you can read it to do it correctly but i'd just use a library

deeplinking isn't used at all

the deeplink redirect uri thing that you see in ios apps... it predates the existence of these flows

and i'd emphasize that for the longest time, facebook didn't care what you did with the tokens. they just wanted to protect the user's password. oauth came from this

you would never deploy an app today that uses a custom scheme as a redirect uri

[flint zinc]

So if deeplinking predates, what would you recommend?

[undone coral]

you can, it won't be meaningful, but it's not OIDC

[flint zinc]

And your opinions on other standards? OAuth2.0? Auth0?

[undone coral]

i don't know what the objective is so it's really hard to say

if you are trying to authenticate someone via a social media login

this has been done a bajillion times

you would just use a library

[flint zinc]

Yea that's not it.

Else yes, I'd have used something else.

[undone coral]

well it sounds like a crypto thing then

which i can't provide help for

[flint zinc]

It's more of "my" thing I guess.

Not usual stuff

Just something new I guess.

But anyways, yea. Thanks a lot!

The discussion was insightful.

[undone coral]

i think you're trying to do some kind of shared unity world thing

or some kind of virtual gallery

i don't know

good luck out there 🙂

maybe just use Okta for user accounts

if you dont' want to use playfab or whatever

[flint zinc]

Saw that, just a tad bit expensive :S

Okta I mean

[undone coral]

https://developer.okta.com/blog/2021/02/26/unity-webgl-playfab-authorization

you can do this all with keycloak as your backend

[flint zinc]

I guess but more of a eco-system? But not just games. Idk hard to explain lol

[undone coral]

but then you have to get a good client library and know what to look for

it's okay

i definitely want to be helpful 🙂

[flint zinc]

Yea, I'm thankful for that.

[undone coral]

i think don't worry about the named pipes thing. but if you want proper login you'll need a backend server

and do sessions

then the "oauth dance" happens between your backend and e.g. facebook

[flint zinc]

Yea, I'm already using session tokens and then bearers

[agile spoke]

Anyone who is good in calculus know how get the rotation of an object given 4 points in world space?

Ex. Click 4 points in 3D Space and create a game object where all Y coordinates 0, would be as close to 0 as possible given those points? (Due to rotating the gameobject so that the base plane of X,Y, (z?) (2D Plane) is close to 0).

[flint zinc]

To make sure the calls are valid.

[flint zinc]

Yea

[high sluice]

so ive a problem, i realised my button isnt working. any idea why? i thought it was the specific instance of button so i tried deleting and making a new button. but still the button doesnt work

[agile spoke]

Because you dont have an event system in the scene?

[high sluice]

i mean, by default shouldnt the button just turn red from a hover and black when pressed, thats the colors ive chosen anyways

and i added an event listener in the Main object, but that isnt really the issue here

i just put a debuglog in it. but i think the issue is the buttons clicks isnt even being registered

[agile spoke]

That is what the event system is for...

[high sluice]

oh

that thing i deleted

ohhh

is there a way to get it back

or just recreate it..

lol

hahaha

omg

[agile spoke]

just recreate it

[high sluice]

OMG

THANK YOU!

[agile spoke]

lol you are welcome. The ES is a pain in the butt

[high sluice]

tldr just leave it there i guess xP

[agile spoke]

Better to create a game object to store all the stuff you dont care about like a game manager object or something

[desert pendant]

I had a quick question about Unity components. I'm currently developing a boss fight that uses a class based state machine. Each attack state holds its own values related to their attacks. My problem is that I am currently only have one state script attached to the boss at a time which removes my ability for my designers to set the attack values in the inspector, I could of course add all the states to the boss which fixes the issue, but then the boss would always be carrying X amount of components that its not using.

I would love some suggestions or if i'm overcomplicating it and to just add all the state scripts. Many thanks!

[agile spoke]

Could you not create a list of classes (serializing them) and then create an ENUM that represents each state and then convert the Enum to a value in the list?

[desert pendant]

I'll give that a try thank you!

[agile spoke]

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

public class EnemyState : MonoBehaviour
{
    [SerializeField]
    public State currentState;
    [SerializeField]
    public List<TheState> states;
}
[Serializable]
public class TheState 
{
    public string stateLabel;
    public float damage;
    public float currentHealth;
}
[Serializable]
public enum State
{
    Attacking = 0,
    Defending = 1,
}```

[desert pendant]

That's similar to what i have, although my states inherit from a base state

[agile spoke]

ah gotcha. Well using enums might help. cast it this way (int)currentState

same for setting it. currentState = (State)1;

[desert pendant]

Could I - in theory - add all the classes as instances in my Boss's main class and then add and remove those instances as components?

or would that be the same as just adding them all as components

[agile spoke]

do you have an example of the classes you are trying to use? If you make them all of the same type (ex public class EnemyState : TheState (inheritance), you could add all of them in a list and they will have additional data, as well as the base data that you want. You could manipulate the rest of the data separately

[desert pendant]

Sure let me put together an example. One Sec

{
  public enum State
  {
        Idle,
        Charging,
  }
  
  BossState currentState;

  void Updaate(){
    currentState.Run();
  }

  void ChangeState(NewState){
    currentstate.OnExit();
    Destroy(currentState);    
    currentState = NewState;
    AddComponent(currentState Type);
    currentState.OnEnter();
  }
}


public class BossState : MonoBehaviour
{
  virtual void OnEnter();
  virtual void Run();
  virtual void OnExit();
}

public class IdleState : BossState
{
  // BossState overrides
}

this is an extremely basic class set up that i'm using

[agile spoke]

no judgement here. All classes should be basic

better if classes can be made as structs though sometimes.

[desert pendant]

For sure, it's necessary for all these to be classes for the moment

Sorry i've tried to make that a little more clear

i'm deleting and adding a new state in the ChangeState function

[agile spoke]

So, What exactly do the programmers need access to?

(from the inspector side)

[desert pendant]

For example, they need to be able to change values in the Charging state. How far the boss will charge, and the time taken to cover the distance

i could initialise those in the script and avoid this issue, but that's not really an option because my designers need access to these settings

[agile spoke]

Did you see my modified code above?

if you put a string in the first position of a class and serialize it, you can name it

Like so

[desert pendant]

That's cool i didn't know you could do that

[agile spoke]

Then they could easily change those values

i dont think I fully understand the rest of what you are trying to do. I would definitely make a public list in your script, if it doesnt show, serialize it, and have them modify values that way.

Would look something like this

[desert pendant]

I can't seem to get it working with a list of a class that should contain other classes that inherit from it

[agile spoke]

the list is made from the base class?

[desert pendant]

Yeah

[agile spoke]

did you make class Serializable?

also make all variables [SerializeField]

[desert pendant]

Ah ignore me i was just being stupid

[agile spoke]

Are the other classes serialized?

[desert pendant]

I feel like i'm being really thick

yeah they are

[agile spoke]

If you modify the list from code it looks like that sometimes

[desert pendant]

I think I'm gonna take a break and think on this for a bit. I really appreciate all the help

[agile spoke]

Sorry it didnt get you where you wanted to be. Good luck... youll figure it out

oh also... need to initialize each class... or it will look like that

[desert pendant]

Thank you, i've been working all day so my brain is just running out of steam 😅

[agile spoke]

I hear ya...
Works at runtime for me, but hides the additional variables.

try to avoid using lists that contain different types, even if the list items share the same base type. that said, to have a good editor experience with this, use Odin

additionally, using classes (instead of struct) for state on a monobehaviour can be very problematic

it is a minefield of errors

especially lists of classes

[undone coral]

what did you mean by this

[agile spoke]

thoughts on Arrays of structs @undone coral that was my first thought

[undone coral]

are you trying to say, how do you calculate the normal of the poly formed by 3 or more coplanar points? (a fourth point will not be guaranteed to be coplanar)

[radiant forum]

I am not advanced

[agile spoke]

imagine in VR, using my controller, when I press the trigger 4 times, I create a list. with those 4 poitns in 3D Space, I want to create a 2D Plane to draw on. but can only do so using those points

[undone coral]

arrays just sort of blow because you can't force them to be copy on write or whatever. but you just have to deal

[undone coral]

gt it

so my suggestion is the UX looks something like

[agile spoke]

also. I need the rotation of a plane due to the fact that other future information needs to derive from the "new" coordinate system

[undone coral]

the user places 3 points with their pointer
create a UnityEngine.Plane with
 those points, and canonically choose a 
 direction for the normal opposite camera
 normal (ie facing player)
render the fourth point "locked" to that
 plane using Plane's closest on-plane point
 to the provided point function

@agile spoke is that helpful?

i see how in a stylistic sense you want to let the user choose a fourth point

so that it feels like a rectangle-like thing

that's fine

[agile spoke]

Not really stylistic as much as using it for averaging

[undone coral]

Plane lets you achieve everything you need 🙂

i wouldn't try to do that for now

i would just use the 3 and cast the 4th onto the plane defined by the first 3

otherwise it will behave weirdly, trust me on this

there isn't a canonical way to "average" 4 points into a plane

so whatever you come up with will be, in that sense, weird

whereas there are exactly two ways to interpret 3 points as a plane (normal is clockwise points out, or normal is counterclockwise points out), and for your application you can always choose something that makes sense

[agile spoke]

i've been messing with runtime manipulation for a while, and have NEVER come across planes... very interesting.

or rather I've not seen this API pop up in my searches and exploring... im surprised it hasnt

[undone coral]

that's why you come to the doctor

i have the medicine you need

[agile spoke]

lol thanks for this. I am assuming that its best that if I do create a GameObject, no need to rotate... I can use the plane functionality to do most of the rest?

[undone coral]

this is meant to be UI right?

[agile spoke]

no...

[undone coral]

like at first

like to visualize the four points the user is choosing

are you having them draw a poly

i know it will manifest as something you put into the world

[agile spoke]

yes in that regard

[undone coral]

okay

you could, in principle, create a game object with a piece of geometry whose arted normal is pointing positive y (i.e. up)

then, to spawn it, set its transform.up to the Plane's normal

that will "rotate" it correctly

as long as you know what it's "art normal" is

meaning, whatever is "facing forward" for that piece of art

i don't mean to be so abstract

[agile spoke]

I understand most of the theory behind normals etc, but in practice my floor is covered in hair when trying to implement

So yes, I understand up from normal, but actually using that info, Im going to have to dive a bit deeper to get the gold of it

[undone coral]

yeah so you will get the .normal from the Plane you created

that's the direction the poly your player made is facing

then you can set transform.forward or transform.up on a game object to that normal

and it will rotate

such that the transform's forward or up or whatever

is in the same direction as that normal

whether you use transform.forward or transform.up depends on which way the art, meaning the mesh, is really facing

a unity plane is facing forward on y positive, so you'd use transform.up

which is contrary to what is canonical, that "forward" (what you are facing) is z positive, not y positive

when you're rendering the UI @agile spoke you'll use whatever library/asset to draw the floaty lines

like the blue lines and fill in the poly

[agile spoke]

that is kind of weird considering their coordinates are mixed up (Y,Z) but the verbage actually makes sense coming from other applications

[undone coral]

yes, Unity adopts maya's coordinate system

the only worthy one

sorry 3dsmax

[raw schooner]

when a class is not a singleton, and no usages of it can be found in other classes, what's the likely way the MonoBehaviour was instantiated by the engine?

[undone coral]

<@&502884371011731486> please block XXX

[undone coral]

can you describe what you're observing and what problem you are trying to solve?

if you have a prefab in a Resources folder

[raw schooner]

lol sorry. i'm not making a game

[undone coral]

and you instantiate the prefab

[raw schooner]

i'm looking at code from an existing game

[undone coral]

i see

you can use tools like DevX Pro to decompile unity games

[raw schooner]

there's a TitleManager : MonoBehaviour, which isn't referenced anywhere else

though it has to be instantiated somehow

i'm wondering what part of unity is doing this

[undone coral]

it can be on a prefab that gets instantiated

there's no reason it would have to be referenced in code directly

[raw schooner]

a prefab is like an asset?

[undone coral]

hmm

you have a long way ahead of you on your unity decompilation journey 🙂

[agile spoke]

^^

[raw schooner]

i'm not modding

literally just reading memory

[undone coral]

for like hearthstone deck tracker style stuff?

[raw schooner]

all i want is TitleManager.m_currentOption

[agile spoke]

Prefabs are assets, yes

[raw schooner]

hm, would help if we had the C++ source

[undone coral]

you have just stepped backward on this journey

[agile spoke]

lol

c#

[raw schooner]

nah the UnityPlayer module is surely a C++ library

[agile spoke]

but the TitleManager wouldnt be

[raw schooner]

well no, but i need to find the prefab somehow

and i have to assume it's in some collection in that module

there are things like g_RuntimeSceneManager, which is the internal SceneManager class

or s_InstanceBehaviourManager

[agile spoke]

I've built my own library for this

[raw schooner]

the latter doesn't even bring up a single google result

[agile spoke]

those are all custom

[raw schooner]

custom how?

they're part of the engine

they're in the UnityPlayer debug symbols

[agile spoke]

ah

so static members?

[raw schooner]

yeah

http://symbolserver.unity3d.com/

in case you didn't know about this

i believe there's a collection of prefabs, or assets, or something like that, just like there's a collection of scenes (literally an array of full scene paths). will be difficult to reverse this

i still need to figure out s_InstanceBehaviourManager as well, since that sounds really good too

[agile spoke]

As someone who is developing something to sell... the talk of reverse engineering software makes me uncomfortable to discuss. They should have obfuscated the software to make it more fun to decode. Im sure youll find more helpful information online

[raw schooner]

someone's always gonna do it, and i'm that one for this

[humble leaf]

But it won't be here, we don't allow decompiling discussions in this discord.

[raw schooner]

sorry, understood

[agile spoke]

@undone coral something like this?

[undone coral]

yes, but you still have to process what that whole discussion about what "up" or "forward" means with respect to your art

[brave thunder]

something can help me with this problem

[undone coral]

because LookAt won't behave correctly for the mesh created by the menu option in unity for creating a plane geometry

[agile spoke]

probably script name is not the same on the script as the class name inside of the script. Look for caps, spaces.
*edit to add. Looks like something extra is there inside of your script

im going to have to play with it for a while.

[undone coral]

okay

but yes, the essentials are there

you just don't know yet i think that you can do

transform.up = plane.normal

[agile spoke]

i learn better by failure, so Im going to have to do the thing

[undone coral]

and transform.LookAt is essentially transform.forward = plane.normal

it is technically

var up = transform.up;
transform.forward = lookAtArgument;
transform.up = up;

[brave thunder]

I tried to do something but I can't solve it

[agile spoke]

so 1... I should be editing the transform.?? values and not look at. 2... consider Unity's orientation

[undone coral]

yes

you can use LookAt... provided your game object art's forward is (0,0,1)

does tha tmake sense what i am trying to say?

your art has a logical "forward"

like your human body has a logical forward

that means soemthing

and a logical up

a plane, which is a square... people ahve decided that it has a logical up

but it does NOT have a logical forward or right

if it's a square

it's just arbitrary

[agile spoke]

most instances the "plane.normal" will be facing close to up, but at an angle

[undone coral]

you can't just look at a picture of a plane and tell me which way is +X and which way is +Z

[agile spoke]

err

forward

[undone coral]

anyway you are going through the expanding brain memes here

of what lal this stuff means

you have Plane you are already in a good spot 🙂

[agile spoke]

yes, yes. Thank you for that tid bit

that does most of the math that i was struggling with

and the rest btw.

[agile spoke]

on your script, this looks wrong. change the script to match the file name

or change the file name to match the script name (class name). They should be exact with no special characters

[brave thunder]

it does not work

sorry

[agile spoke]

post the script here?

type 3 ` before and after

ex. my code

I guess I should ask the obvious too

are there any console errors?

[undone coral]

kind of #💻┃code-beginner maybe start with a unity tutorial

[strange hornet]

so, spherecasts; can't live with 'em, can't live without 'em.

I have a really awesome bullet system set up with realistic (ish) penetration and ricochets. I love it. The issue I'm running into now though is that if I put shotgun rounds in an smg I quickly slow to a crawl after 10 shots (maybe 250 projectiles?)

obviously not being able to stick 9mm pest control rounds in my smg is a massive bummer. The profiler says my bottleneck is spherecasts, which I do 2 of per bullet (for entrance and exit logic)

does anybody know any strategies for reducing the performance hit on spherecasts? I figure I could at the very least do my bullet updates half as frequently, but they're already in fixedUpdate which updates relatively slow. tbh I would need like a 10x performance improvement to make shotgun smg viable

[agile spoke]

It works great, thank you.

[agile spoke]

Could you not use raycasting at all and let the items have spheres on them(if my memory serves, spheres have less performance hit than box colliders), attach events to those if they hit a target in the OnColliderEnter type deal?

[strange hornet]

🤔 honestly I've assumed this wouldn't work because of the high velocity. When I've tried to use physX before at realistic speeds (1000 fps or more) there's tons of issues with things just passing through walls

maybe I'm wrong about this

[agile spoke]

You could just create a wall with a box collider and see, maybe you are right though.

could you create a spline for the bullets path, and each line segment, run a ray trace?

could run the math logic in a separate thread and recieve the results in update loop. Ex (if(finishedCalculatingLinePath), (raytraceAlgorithm());

[hushed fable]

Spheres should be the cheaper primitive.

@strange hornet Are you triggering GC.Collect perhaps? Is SphereCast the only detail it gives you on profiler?

[strange hornet]

yeah basically. just 200+ spherecasts. I'm already using SphereCastNonAlloc

I'm realizing my FixedUpdate is running at like 50fps which is probably insane. going down to 5fps might actually be viable though it could potentially screw up hitreg

[hushed fable]

Not sure if changing the rate is the solution if the frame is too heavy, since you would essentially just change the frequency of the stuttering.

[strange hornet]

hm good point. maybe they could be staggered or something though

that's worked for me before with raycasts, has some weird consequences of course depending on how you choose to order them

maybe i'm interpretting this wrong tbh

[agile spoke]

What about an initial raycast? if it hits anything other than ground, enable the other checks?

the individual spherecasts dont seem to being using much...

what else is in the FixedUpdate Function? Any allocations, assignments? Instantiating prefabs? Do you use object pooling? So you can update its values instead

[strange hornet]

yeah there's object pooling. there's a bunch of math happening but I assumed that would be shown in the profiler. here it is not-raw, I guess technically spherecasts are only 11% so maybe that means my math is heavy?

I'm basically substepping inside of the loop to do friction... didn't think this was an issue but maybe

[strange hornet]

I guess I should probably do some more in-depth testing of how long each section takes

[regal olive]

What actually does initialize mean

Everything I read says Start() is used for initializitionnnnn

[agile spoke]

You should probably read this https://docs.unity3d.com/ScriptReference/MonoBehaviour.html

and then this https://docs.unity3d.com/ScriptReference/MonoBehaviour.Start.html

[agile spoke]

Not sure if raycasts can be run in other threads? but this is kind of how I saw it. Each bullet path broken down into segments, and running a raytrace on each segment. faster or slower? dunno.

but you could in theory, run it in a coroutine and that way it checks the 1,2,3 in the first segment of each bullet and each other one respectively. That way you might not have to thread but could check if each bullet hit anything on the very first frame, giving you enough time to run the others by the 2nd frame most likely

[regal olive]

DONT CLIKC

dont click

its a virus

steals discord accounts

[carmine light]

thanks

banned

[undone coral]

looks really sick, pretty much exactly what i imagined

[agile spoke]

Well, you cant see much from that view lol. Ill share video at some point.

@strange hornet Or something like this

using System;

public class Bullet : MonoBehaviour
{
    [SerializeField]
    public BulletSettings bullet;
    private float step = 0;   
    public int stepsPerFrame;
    private Ray ray;    
     void Start()
    {
        bullet.velocity = transform.forward * bullet.speed;
        bullet.gravity = Physics.gravity;        
        ray = new Ray();
        bullet.stepSize = 1.0f / stepsPerFrame;
    }
    private void Update()
    {
        bullet.pos1 = transform.position;
        bullet.temp = transform.position;
        
        for (step = 0; step < 1; step += bullet.stepSize)
        {
            bullet.time = Time.deltaTime;
            bullet.Run();            
            ray = new Ray(bullet.temp, bullet.val);
            if (Physics.Raycast(ray, (bullet.val).magnitude))
            {
                Debug.Log("I HIT SOMETHING!! -- NOW DO SOMETHING");
            }
            bullet.pos1 = bullet.pos2;
        }       
        transform.position = bullet.pos1;
    }    
}

[Serializable]
public struct BulletSettings
{
    public float speed, time, stepSize;
    public Vector3 velocity, gravity, pos1, pos2, val, temp;          
    public void Run()
    {        
        velocity += gravity * stepSize * time;
        pos2 = pos1 + velocity * stepSize * time;
        val = pos2 - pos1;        
    }   
}

Edited to fix

[strange hornet]

this is more or less what I'm doing, with many more steps and calculations. except instead of doing stepsPerFrame sphereCasts I just do it once and apply the change in velocity 1-dimensionally in the substeps. cuts down on casts by like 95% lol

friction calculations don't play nice with continuous functions 🙄

this means that gravity isn't applied until the end of the frame and bounces require a recast

or any 3-dimensional change in velocity

[agile spoke]

I did want to ask... are you sure you can jobify raycasts?

[strange hornet]

I'm pretty sure you can't, there's a bottleneck due to needing to access the scene information

[agile spoke]

yes, but from the profile it looked like it was being "jobified"

[strange hornet]

would be really rad if you could bulk query the scene for an arbitrary amount of casts but I don't see that functionality anywhere 😵‍💫

[strange hornet]

OH yeah I noticed that when I posted it... not really sure why

I'm just doing them in fixedUpdate

it does seem like they're doing a lot of job waits though

[agile spoke]

Almost all devices using Unity are multi-cored with at least 4 cores. I feel like they should find a way for sure to make all data accessible on any thread.

[gray pulsar]

not sure if this is what y'all are looking for, but: https://docs.unity3d.com/ScriptReference/RaycastCommand.html

[agile spoke]

maybe make a flag in the gameObject such that when any gameObject is being manipulated it is pushed ignored.

then add it to a list of go that were ignored

then check list again

[agile spoke]

looks pretty useful, not sure what hes using

[strange hornet]

for each bullet in FixedUpdate. one cast forward to get entrance points, one cast backwards for exit points

[strange hornet]

do you know if there are any negative implications of doing this? timings, etc?

[gray pulsar]

I just know it exists. Never used it, don't know anything about it

[agile spoke]

have you tried removing "var" and seeing performance?

not saying its anything... but I never use var

[strange hornet]

looks extremely promising. thanks for the tip

[strange hornet]

I could be wrong but I would think vars are resolved on compile, not runtime

that being said no, I haven't tried that

[agile spoke]

you are probably right, its just a habit I have to eliminate any source of potential problems.

[undone coral]

why is it a spherecast exactly?

because the bullets have a size?

[regal hill]

Hello, I have a problem with my tilemap.

when I go this;

    [SerializeField]
    private Tilemap tileMap;
    // Start is called before the first frame update
    void Start()
    {
        Tile tile = (Tile)tileMap.GetTile(new Vector3Int(0, 0, 0));
        Tile tileTest = (Tile)ScriptableObject.CreateInstance(typeof(Tile));
        tileTest.sprite = tile.sprite;
        tileTest.color = Color.red;
        tileMap.SetTile(new Vector3Int(0, 0, 0), tileTest);     
    }
``` it's work , the cell at position 0,0,0 change color to red color

but with costum tile :

[Serializable]
[CreateAssetMenu(fileName = "New Tile", menuName = "Tiles/costum Tile")]
public class TileTest : TileBase
{
    public Sprite sprite { get; set; }

    public Color color { get; set; }
 
    public Matrix4x4 transform { get; set; }

    public GameObject gameObject { get; set; }

    public TileFlags flags { get; set; }
    public ColliderType colliderType { get; set; }

    public override void GetTileData(Vector3Int position, ITilemap tilemap, ref TileData tileData)
    {
        tileData.flags = flags;
        tileData.transform = Matrix4x4.identity;
        tileData.sprite = sprite;
        tileData.color = color;
        tileData.gameObject = gameObject;
        tileData.colliderType = colliderType;
    }


    public override void RefreshTile(Vector3Int position, ITilemap tilemap)
    {
        tilemap.RefreshTile(position);
    }
}

and

    void Start()
    {
        Tile tile = (Tile)tileMap.GetTile(new Vector3Int(0, 0, 0));    
        TileTest tileTest2 = (TileTest)ScriptableObject.CreateInstance(typeof(TileTest));
        tileTest2.sprite = tile.sprite;
        tileTest2.color = Color.red;
        tileMap.SetTile(new Vector3Int(0, 0, 0), tileTest2);
    }
``` the sprite is changed but not the color

[undone coral]

@strange hornet okay... here's a better question. is there a rigidbody or a collider on your bullet prefab?

[undone coral]

instead of dumping the code can you succinctly say what your issue is

[regal hill]

the problem is that with My class which inherits from TileBase, when I modify the sprite it works but the color does not change

[undone coral]

@strange hornet also, do you have deep hierarchies?

can you try flattening the hierarchy on your static geometry / make sure static is checked on all static things, and make sure that whatever has colliders and/or rigidbodies on it is just located in the top level hierarchy of the scene?

[undone coral]

properties are not serializable

also get tile data is weird

all this code is weird

what are you trying to do?

you have weird spacing

are you using an IDE?

you should probably get started with the pins in #💻┃code-beginner

[regal hill]

it's the copy/past

[undone coral]

this for example

[regal hill]

i try to change the tilemap in runtime

[undone coral]

this tells me you are not using an IDE

i mean, you clearly are using an IDE

but it's not set up

[undone coral]

okay

i think you'll figure it out

this is weirdly written*

[regal hill]

it's juste the copy/past of my code ^^

[undone coral]

if you need to change the color of a sprite, reference the sprite and change its color

this scriptable object is strange

[regal hill]

Yes it's pure test

[undone coral]

i'm not sure what it does, or why you're using it

[regal hill]

I followed the doc

try*

https://docs.unity3d.com/ScriptReference/Tilemaps.TileBase.html

https://docs.unity3d.com/ScriptReference/Tilemaps.TileBase.GetTileData.html

[regal hill]

this is the only way to change a tilemap at runtime according to the docs

[undone coral]

okay

i see now that you are doing a collider Contains query

try not doing that

i don't know, there's a lot of work to make this efficient

[regal hill]

I think I finally succeeded

thank U

[strange hornet]

oh, penetratingCollider is a poorly named HashSet. not doing contains on a collider

[strange hornet]

yes, all bullets have a diameter

[strange hornet]

I think there is one collider but it's disabled. The main thing it is is a tracer mesh that I'm also updating each frame, but since that isn't visible in the profiler I don't think it's that

[lost dove]

Is there a way to check if the player setting force single instance option is enabled at runtime? Or alternatively check if the current build is a "development build?"

[austere jewel]

#DEVELOPMENT_BUILD is defined in development builds

[lost dove]

Perfect, thanks!

Just out of curiosity, does anyone know how Application.genuine works? Is it just checking the current assembly hash against an embedded "proper" hash?

Or is this only a iOS/Android feature? Because the docs don't mention anything about Windows, only Mobile

[austere jewel]

The sources is in C++, though it does read like it's mobile-only based on this https://forum.unity.com/threads/application-genuine-is-it-worth-to-use.902102/#post-6287441

[lost dove]

Ah okay yeah, this definitely isn't what I'm after. Thank you again!

[high sluice]

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

public class Main : MonoBehaviour
{
    void Start()
    {
        SaveSystem.LoadPlayer();
        StartCoroutine(SaveGame());
    }

    //private void Update()
    //{
    //    SaveSystem.SavePlayer();
    //}

    private IEnumerator SaveGame()

        Debug.Log("saved");

        yield return new WaitForSeconds(3);
    }

}```
why doesnt this work? it works when i use the update instead of coroutines. but shouldnt they both work?
the same function, saveplayer is called, so that should be working and im implementing coroutines wrongly im guessing?

[cursive horizon]

how does it not work? do you get an error? my guess would be that you have some stuff in other components' start methods that your SavePlayer method relies on, which are all called before update (so save works from there)

[high sluice]

idk the coroutine just isnt being called

other components start methods?

if i commented out the coroutine when i ran it in update

[cursive horizon]

you aren't using the coroutine in update

[cursive horizon]

I doubt that, unless you don't have this component attached to anything in the scene. Start should be called...but you can confirm I suppose

[high sluice]

yea, coroutine is different from update right?

er the console log shows that coroutine is called once and then isnt called after

[cursive horizon]

well sure, that's what you do

you call it once in start

[high sluice]

i made save player output something to console so thats also called exactly once

yea, but shouldnt it be called every 3 seconds

[cursive horizon]

you don't do anything after you wait 3 seconds, so no

[thin mesa]

see this is why you shouldn't crosspost because i just told you in #💻┃code-beginner that it doesn't loop

[cursive horizon]

it will save the game, wait 3 seconds, and then terminate

[high sluice]

wait so, how would i do it such that this is called every 3 seconds

[cursive horizon]

well if i were you, i would just keep track of time and use the update loop

[high sluice]

hm so something like having a variable for last update and if its 3 seconds since, i run the save and update the lastupdate variable?

[cursive horizon]

yep

[thin mesa]

you could also just put everything within the coroutine into a loop

[high sluice]

what exactly is coroutine for?

[cursive horizon]

it's just another way to express the same thing really

you could do it either way

but if you aren't familiar with coroutines, stick to using the update loop until you get a handle on programming frame-to-frame

[high sluice]

hm i see thanks

[cursive horizon]

and then coroutines will make much more sense and can help simplify some things

[high sluice]

also i wanna make a game where i can keep track of time offline

is there a way to get absolute time

[cursive horizon]

you can get the system time

[high sluice]

idk if thats the proper word

[austere jewel]

🌈 do not cross-post

[cursive horizon]

System.DateTime.Now

[high sluice]

mm thanks

[thin mesa]

alternatively Time.time returns a float representing the time (or rather time since application start) rather than a DateTime and would be easier to work with for a simple timer

[cursive horizon]

isn't Time.time just since the game started? they said they want offline time

[austere jewel]

That is time since startup

[thin mesa]

yeah i didn't see that, that's my bad (thought they were still asking about the timer for delaying their SaveGame call)

[lost dove]

Also there is the InvokeRepeating method

Since it's not called super often, it might be suitable

You can also use System.Diagnostics.Stopwatch in a coroutine loop

[strange hornet]

interesting results... every bullet loop I do 2 spherecasts (forwards and backwards)

apparently the 1st one takes roughly 16x as long as the second one. No idea why, but it's consistent

actually it ranges pretty wildly, between like 8x and 20x

makes no sense

in theory they should be a nearly identical operation since they have the same distance and aren't hitting anything

confirmed that most of the time is spherecasts though. although my maths are definitely heavier than I expected and also I have a LINQ call that really sucks (hitOrdering)

specifically most of the time is forward spherecasts 🤔

hey guys, how would i go about making a savable list in JSON?

can i just have a list of ints or strings and save it without doing anything to it?

[strange hornet]

yes

I recommend the json.net package https://assetstore.unity.com/packages/tools/input-management/json-net-for-unity-11347

[mighty cliff]

oh sick

Thanks man

[strange hornet]

@mighty cliff

[mighty cliff]

cool

[strange hornet]

so there's a SphereCastCommand... but unfortunately it doesn't do multiple hits like SphereCastAll so I don't think it'll work 😭

Is there no time keeping mechanism in Bursted jobs?

I have a very expensive loop in a Bursted job that may take some time to complete, and I'd like the job to be aware of time and exit early if it has exceeded for example 10 ms.

I guess I could pull the loop out of the job and make the job only executes one operation, and let the main thread that execute the job to do the time keeping

But I'm under the impression that the overhead of starting a job might make this not viable.

[lost dove]

probably better to ask in #archived-dots

just properly learning about GC for the first time ... is there some kind of primer on how much GC it's okay to cause? or do i actually need to aim for 0, i'm not sure how that's possible, like startcoroutine seems to be guaranteed to do its 64B or whatever

like i'd guess to just watch the actual CPU usage of the garbage collector blips in the profiler to see if there's a problem, and generally at least keep things in the random occurrences of a few hundred bytes instead of like kilobytes every frame

[sage radish]

That's how I approach it. You can also try the relatively new Incremental Garbage Collector in Unity, which is supposed to reduce big spikes.

But optimizing something that used to allocate a bunch to allocating zero is very satisfying, regardless of whether it actually improves performance.

[gilded wing]

yeah lol it's very ... gamified

[scenic forge]

You may want to look into UniTask.

It's zero allocation and you get to use async/await instead of the ugly and unmaintainable coroutines.

[hushed fable]

FYI, you probably already have Newtonsoft JSON package from Unity if you have a modern version of Unity, since Unity's Version Control package depends on it.

[mighty cliff]

oh okay

[fresh basalt]

Any idea why this ``` public bool CheckWritePermissions()
{
if (!Permission.HasUserAuthorizedPermission(Permission.ExternalStorageWrite)) {
Permission.RequestUserPermission(Permission.ExternalStorageWrite);
return false;
}
return true;
}

returns false, but the popup for permission check doesnt appear?

[red ingot]

Can someone help me with this player code?
My character is not jumping
Here's the code:

[merry cedar]

Try to keep track of your conditions

Does your jumpkey actually do something ? Does your ground check work properly

Abuse debugging and you'll find quick enough

[tough tulip]

maybe because the permission doesn't popup if the user denies it in settings

or denies it more than once

[fresh basalt]

yeah, i figured it out. Thanks

the weird thing is, even tho the user allows the permissions, in code when i check it still is false, no matter if the user allowed it or not

[tough tulip]

dont return false after requesting for permission. return Permission.HasUserAuthorizedPermission(Permission.ExternalStorageWrite) instead

[fresh basalt]

ok

but i dont understand how that will fix

my problem

nope, still the same. Permission.HasUserAuthorizedPermission(Permission.ExternalStorageWrite) always returns false

[tough tulip]

because requesting permission pauses the application depending on the device. i have came across few devices which donot pause, but most of them do.
anyway do you use custom manifest?

[fresh basalt]

nope. It even happens when i restart the app

i tried uninstalling it, installing it again and enabling storage permissions through settings

still the same

I have a bit of a hard question since I dont really know how to explain it but I want to create a globe where the player can orbit a small globe that can change terrain the further you go, even if you did a full cycle around the globe. Eventually, the terrain will repeat if you go even further too. I drew a picture if that helps to visualize.

Like the shrinking world game brackey made but instead of it shrinking, the further on the road you go, new custom terrain shows up, even if you go all the way around

Sorta like an illusion

[fresh salmon]

The "easiest" way to do this would be to have a flat generated terrain, and a camera effect like a shader that deforms the view to give the impression of a planet

[regal olive]

Ohh yes! Thats a good idea, will it deform the player tho?

[fresh salmon]

If applied on the camera, yes.
You could have two cameras though, one with the effect that renders everything but the player, and another that just renders the player, with no effects

[regal olive]

Ok great! Do you know a tutorial on this affect?

[fresh salmon]

Nope

[regal olive]

Ok

I gotta try to find something online then

But first, Ill model the flat terrain

[humble leaf]

The Curved World asset does exactly this

Great thanks!

I have a "working" piece to get mic input actively as I need to read just whether the player is talking or not, going based on "amplitude" (as all the google'ing has lead me). And for some reason, there is a LOT of noise being picked up as well, even when mic gets unplugged (Have a slider to display before and after of mic filters, and the raw/before just keeps going up and down on its own when room is dead silent or mic unplugged - using headphones through monitor and as loud as possible, no sound can be heard from mic when it spikes very often randomly)

Samples mic every 1/10th of a second, with a sample data length of 1024*
