I am aware I can do this with extensions btw, i am curious if you can do it inside the class thought

[flint sage]

Assuming I understand, you could do this but that would require you to instantiate TestColor instead of Test1 which is probably not what you want

class Test1<T>
{

}

class TestColor: Test1<Color>
{
    public void Blur()
    {

    }
}

Otherwise extension methods is the way to go

[sinful fossil]

Surprisingly I didn't think of that but it isn't what I am looking for, thank you though!

[flint sage]

Yeah in that case, extension methods

[hardy nymph]

is it possible to convert euler angles to quaternions in javascript ?

[flint sage]

It's just math so why not

[hardy nymph]

Oh okay

I will try

DOTS physics is also deterministic (on the same machine)

Havok may even be less deterministic by default. DOTS physics is stateless but Havok is stateful.
https://docs.unity3d.com/Packages/com.havok.physics@0.6/manual/faq.html

[ashen shard]

While you could do this with extensions, you generally want generic classes to be, well, generic. If you're changing behaviour depending on the type there's probably a better option.

Hi. I’m making a physics based spaceship game where ships are rotated by torque. To make sure enemies can aim correctly and not overshoot, I use PID controllers. It works very well enemies have very good aiming.
The problem is once I start the design process of tweaking the torque power of the enemies, the pid controller is broken and the controllers need to be tuned. This makes the iteration time painfully slow

Has anyone dealt with a similar issue? I’ve used a genetic algorithm to automate PID learning but it takes 10mins with the computer at 100% so iteration is still slow

I’m considering if PID controllers are the best solution

[compact ingot]

so long as you stick to correctness/realism as your top priority, a PID approach is your only option. If you opt for a less simulation driven (kinematic) approach you can do it all with closed formulas and interpolation

at the end of the day what matters most is game feel and correct physics usually get in the way of that.

[wintry wind]

I think there’s a holy grail somewhere in this problem though. I think there should be a way to automatically tune (ie deterministic, without genetic brute force) PID controllers based on the max angular acceleration. I’m just not good enough at math to figure it out lol

Realistic and feeling good movement are pillars of this game and why I invest a lot of time in it

[compact ingot]

Tuning a real physics thing for a specific effect is very difficult and not something easily automated. Just look at tuning/setting race cars and launching rockets or walking robots. It’s a black art, a slow iterative process, ML can help.

[mint sleet]

Hello!

My managers are derived from the same base class. I can not assign them to base classes' array field.

[austere jewel]

You're not dragging an instance into a field. They must be instances of components or scriptable objects to be serialized references.

[mint sleet]

hmm I'll initialize them via constructor then. @austere jewel

[austere jewel]

If they're not UnityEngine.Object types, that's definitely how you do it

[mint sleet]

Thanks!

[snow flint]

hi guys, trying to use reflection to call a method on a class but getting this error that is commented in the code, but sure what it means tbh..

        {
            Type myType = typeof(UnitStats);
            FieldInfo myFieldInfo = myType.GetField(statInfo.Name, bindingFlags);
            if (statName == statInfo.Name )
            {
                // ArgumentException: Field moveDistance defined on type UnitStats is not a field on the target object which is of type System.RuntimeType.
                object myObject = myFieldInfo.GetValue(typeof(UnitStats));
                MethodInfo myMethodInfo = myObject.GetType().GetMethod("");
                object[] args = new object[] { percent };
                myMethodInfo.Invoke(myObject, args );
                return 0;
            }
        }
        return 0;```

[austere jewel]

GetValue(object obj), obj is an instance of the type you're getting the value from. It's not the type.

(if the member is static that instance is just null)

[snow flint]

right that makes sense, the instance isn't static, need to think what this instance should be i think i know it

thank you

[timber flame]

I have octree GetNearBy method by max distance (radius) but I want k-nearest neighbor. How can I change it?
Because finding neighbors using radius sometimes for example returns 3 points and sometimes 100! It is not fixed
Do I have to sort the result or add them in a heap (priority queue) when finding them?

kLog(n)
n: number of result points
k: number of nearest points

[snow flint]

hey mate, i wanna return a value from the method invoke is that possible? it doesn't seem possible
return myMethodInfo.Invoke(myObject, args );

[austere jewel]

It returns an object, you just need to cast it to the type you're expecting

(or keep it as object if you don't know what it is)

[snow flint]

oh of course, ok thank you

[cerulean scaffold]

Hi everyone, when I assign a value to a float without any calculations, like for instance
float myFloat = 7071077f, it should always be exactly the same value on different x64 machines, because floats are 'accurate' by up to 7 digits, correct?
(And if I would assign a value with 8 digits, float myFloat = 70710771f it wouldn't always be exactly the same value)

[sly grove]

No, there's no number of digits in particular that guarantees this. The number of digits is a rough estimate

[cerulean scaffold]

hmm, okay then I'll have to look out for that. Thanks!

[cerulean scaffold]

Kimbatt's deterministic physics implementation uses floats this way (although for in-place casting instead of field assignment).
https://github.com/Kimbatt/unity-deterministic-physics
Here you can see an example in his readme on soft floats: https://github.com/Kimbatt/soft-float-starter-pack
In his testing he seemed able to get away with it 🤔

For floats with more than 6 digits he's using hexadecimal values like this

public static sfloat FromRaw(uint raw)
    {
        return new sfloat(raw);
    }```

sfloat k_cosMaxMergeAngle = sfloat.FromRaw(0x3f3504f7);```

[devout hare]

Seems to be quite a lot of conceptual/terminology misunderstandings here

if something is accurate up to N digits, it means by definition that it's inaccurate after N+1 digits

so if you have numbers 0.70710701f and 0.70710702f they're both accurate to 7 digits but not the same number

That said, I'm pretty sure (but not certain) that float constants are the same everywhere. The issues come from operations like addition (0.2 != 0.1 + 0.1)

[cerulean scaffold]

That's what I assumed aswell but I couldn't find any information on it 🤷‍♂️

[devout hare]

At least that's what the soft floats library thing assumes

[cerulean scaffold]

But for large numbers he uses hexadecimal values in his code

[devout hare]

I don't see any evidence of that?

sfloat a = sfloat.FromRaw(0x00000000); // == 0
sfloat b = sfloat.FromRaw(0x3f800000); // == 1
sfloat c = sfloat.FromRaw(0xc2f6e979); // == -123.456
sfloat d = sfloat.FromRaw(0x7f800000); // == Infinity

0 and 1 are not large numbers

[cerulean scaffold]

For instance minDistanceSq is 1e-10
https://github.com/Kimbatt/unity-deterministic-physics/blob/master/Assets/Scripts/UnityPhysicsPackage/Unity.Physics/Collision/Geometry/ConvexHullBuilder.cs

so he uses sfloat.FromRaw()

But for values like 2.0f he simply casts to sfloat

[devout hare]

That might be just a style issue, or the reference values come from somewhere. You'd think that it would be mentioned in the documentation otherwise.

[cerulean scaffold]

Idk, should I notice that casting floats with lots of decimals to sfloat not being deterministic I'll give FromRaw() a try 🤷‍♂️

[undone coral]

you're fighting the good fight

[undone coral]

this is an interesting project

[undone coral]

VR Cloud Manager
you're on the start of a very, very long journey

i forget, the plugins, are they streaming something? data or audiovideo?

[undone coral]

did you consider authoring a physics engine with networking* as the primary goal?

there is a lot of gameplay that works with that

with those constraints*

it's networked right, that you're after, not necessarily deterministic?

[cerulean scaffold]

no, just physics for my wip rts game. But who knows, parts of it might end up on the Unity asset store, but not anytime soon.

[undone coral]

as a single player game or multiplayer?

[cerulean scaffold]

I'm using lockstep networking. If physics should actually be relevant to the gameplay it has to be deterministic.

[undone coral]

https://github.com/skyteks/WarKingdoms is this you?

oh no

[cerulean scaffold]

nah

[undone coral]

that's Skyteks he's actually in this server lol

[spring lake]

Is it possible to convert a world position to screen position even outside the camera frustum?

Sometimes, the built-in functions returns some weird numbers so, is there a workaround for this? This is somehow related:

https://forum.unity.com/threads/worldtoscreenpoint-bug-returning-huge-numbers.536564/

But I don't intend to do the same thing. I'm trying to get the screen coordinates of the 4 corners of a plane without clipping the results.

[wintry wind]

I had an awful experience trying to do that. Ended up using this but my use case is not the same as yours but maybe you can re-use it https://github.com/jinincarnate/off-screen-indicator

[mighty viper]

PLEASE! Is here anyone who can help me with netcode? I'm loosing all my braincells!!!

[fresh salmon]

Yes, in #archived-networking

[mighty viper]

thx

[undone coral]

this is nice

[undone coral]

i also have seen this issue. many people have

i am not 100% sure why it occurs. I used to believe it happens because the camera is moving

[wintry wind]

I think it happens when you get close to the 90deg angle to the camera

Because if you think about it 90deg from the camera would be infinite

[spring lake]

yeah this is not my use case but thanks for this! I'm afk now but I'll see if there's something I can get after I get back.

[spring lake]

this makes sense but I don't think it only happens at that angle, I'm not sure as I still cannot determine tbh. All I know is if it's outside the frustum then it becomes pretty random at times.

[visual shore]

hi, not really advanced but other channels seem to be in use, i've created a scriptable object but it won't show up to be created despite the [CreateAssetMenu] attribute and i have no idea why

[sly grove]

#archived-code-general is a fine place to ask

[visual shore]

thanks :) i just thought i should wait a bit in case someone replied to the one above

[upbeat path]

post your code to a paste site

[visual shore]

https://hatebin.com/rthvbgphis :)

[upbeat path]

[CreateAssetMenu()]

[visual shore]

still isn't showing up :/

[upbeat path]

Then you must have a code error because it works for me

[visual shore]

yep had a code error in another script thank you!

[upbeat path]

Always, always, always check the console

[inland prairie]

Hello, I just noticed in my code I have some reference to GameObjects that are active (activeSelf = true, activeInHierarchy=true) but they do not exist or are not visible in the Scene on the Editor.
Such reference is a static reference to a GameObject

static GameObject cameraObject;

I wonder if somebody can help me understand what is happening here.
Thasnks!

[sly grove]

what are the hideFlags?

Also

is it a prefab:?

Prefabs don't exist in the scene

[inland prairie]

hideAndDontSave

[sly grove]

ok so it's hidden

that's why you don't see it

https://docs.unity3d.com/ScriptReference/HideFlags.HideAndDontSave.html

[inland prairie]

duh, that makes sense, I didnt know you could set flags to a GO to hide it on the Scene

thanks for the clarification

[mint sleet]

No it's not like it seems. It's a communication library for our backend. 😀 But cool name is not it

[undone coral]

lol

gotchya

[little trench]

Does anyone have any experience with digitally signing unity .exe files on Windows 11? Would like to get rid of that ugly "don't trust this software" screen.

Main question is if you need a cert from a CA, or if you can self sign?

wow, these bloody certs are expensive!

[regal olive]

How much lol

[little trench]

hundreds of dollars

[regal olive]

Also how do those thousands of games on steam for example not have that?

They certainly dont just buy certs right

[little trench]

from https://www.reddit.com/r/Unity3D/comments/645y7k/should_i_digitally_sign_the_stand_alone_player/

"If you're worried about the message popping up when launching via Steam... it won't. Steam games are run through their launcher which avoids these issues. This also solves the bigger problem of unsigned Mac games not even being able to run without Gatekeeper disabled.

tl;dr No need to sign it for Steam, do it elsewhere if you really want to."

[regal olive]

Ah

[little trench]

I'm distributing on itch, I haven't looked into Steam, but my understanding is its a pretty involved process to put something on Steam.

[regal olive]

Still sucks though if you wanna let people buy/download from your own site

[little trench]

doing a little more research, I'm wondering about the implications of signing a project with an IV cert, or if you even can? I don't currently have a business license.

[regal olive]

Isnt there something like certbot, which is for ssl, but for applications?

[little trench]

I answered my own question. With anything less than an EV cert, you have to have thousands of downloads verified to build reputation with Windows Defender Smartscreen, and not see the warning message. With an EV cert, you get automatic recognition.

It looks like you can qualify for an EV cert as a Sole Proprietorship. You would need to get a DUNS number, or a letter from a CPA.

Honestly, I'm going to do some research on deploying XR Interaction Toolkit apps to Steam VR. That might be a lot cheaper, and less legally fraught.

(talking to myself at this point, sry!)

[regal olive]

Duns number uuuhh yeahh no idea lol

Just let 1000ppl test ur game i guess :S

[mint sleet]

Hello!

What is the best way to store API endpoints in unity? I want to put them all into a static class as constvalues. Is this approach ok?

I have almost one hundred APIs

[pliant crest]

generally you have a repository

[tidal solstice]

we used that approach for a multiplayer game at my old company. we had about 20-30 endpoints written as constants in a static class. you can make nested static classes for different categories of endpoints, so the code is easier to read and navigate through

it worked out fine for us. the endpoints all had the same base URL, which we stored as a separate constant that was referenced by them (easier to change from development to live APIs and vice versa).
the main thing to watch out for is not to publish builds with the wrong base URL (for this, you could consider a configuration file or something similar)

[pliant crest]

i could understand that being a config file or something

but wouldn't you just wrap it in a repository

why have statics

if anything it would be constants in the repo

or a scriptable object

[tidal solstice]

if all he needs is a place to get some unchanging URLs from, a repo is superfluous, imo.

a SO is a good option too, and it's more editor-friendly, but then you have to keep a reference to it somewhere so you can access its values

[scenic sapphire]

Hey, i wonder if you can overwrite in an extended class a field from the base class

So if i have ItemPicker with an Item type field. Create an ItemPickerExtended with ItemExtended field (without creating additional fields)

[gaunt spoke]

I'm not sure thats a thing, you can use Item base type in ItemPickerExtended and use

if (item is ItemExtended itemExtended)
{
  itemExtended.DoExtendedStuff();
}

[hearty venture]

@scenic sapphire u cant override fields, only methods, you can technically hide an inherited field by doing something like:

public new bool ShouldHide = false;

in the derived class, this will cause an error if both the base and derived class serialize said field.
Alternatively if the 2 fields have the same base class then just keep the one in the base class.
For example:

public class A
{
    public Item item;
}

public class B : A
{
    public ItemExtended _item;
}

A.item can store instances of ItemExtended but B._item can only store ItemExtended not Item

[scenic sapphire]

great explanation, appreciated

[real plume]

hello. i was told by phota to ask here: why
Debug.Log(cellDict[tileLocation].Position); reports position
but
Debug.Log(cellDict[tileLocation] == null); reports true ------- here is code, sorry in advance for all the comments but i figured it was better not to delete bc then our lines wouldn't line up http://pastie.org/p/00uBFlm9AK1ihr1j7QmaoR

[real plume]

true as in null

[flint wraith]

yeah, this part specifically

last 2 lines, first debug reports true but last line can get position

[real plume]

thank you, i should have included that. i'll save it for the future. also sorry about misspelling your name there xD

[mint sleet]

what do you mean repository? monolithic approach can be done here as well?

I have written the API as monolithic with 3 physically separated layers. But have not seen any example how to communicate with the backend in Unity in this way

That is why I am making a library that consists of managers and a general manager, to make the unity frontends job easy, they all will be using only Unity Objects to interact with the backedn.

[hearty venture]

@real plume what happens if you use a single Debug.Log?

[mint sleet]

Thanks!

Ill stick to this approach!

[pliant crest]

just to confirm when you say api endpoints

you mean rest apis right?

or graphql etc...

[mint sleet]

yes, rest apis

[pliant crest]

have you heard of the repository pattern?

[mint sleet]

not for unity

[pliant crest]

don't think it matters if its unity or not at that point

cause repositories normally get DI'd but you can't do that in unity

so i guess you just hold it in a some sort of reference object

[mint sleet]

but there is no DataAccess layer in unity since Unity won't be calling DB functions.

[pliant crest]

its not necessarily just for sql data

the datasource can be from anywhere

like rest apis

[mint sleet]

hmm. have not thought about that. you re right!

[pliant crest]

its why repos are normally interfaces

base implementation + concrete where ever the data is

[mint sleet]

but then the responses of APIs matter a lot. They need to be in the same pattern and a very good error handling should be done.

otherwise the unity side blows up. Am I right?

[pliant crest]

then you need single point of entry

that has a validator that runs through

generally i would use fluent validation but have nfi whats supported in unity

[mint sleet]

I used fluent too in the backend

[pliant crest]

why is it 100 api end points btw?

i'm sure you can break it down into multiple parts

[mint sleet]

No we have about 40. its just exaggeration 🙂

[pliant crest]

fair enough

[rugged radish]

first, I'd check for == override for that class and confirmed there's no weird null equality condition there, something like "it equals null when instance isn't initialized with values"

[real plume]

apologies i missed your message. what do you mean single?

[mint sleet]

thanks @pliant crest

        public class OnLoginAttempt : UnityEvent<bool, float> { }
        public class OnLogoutAttempt : UnityEvent<bool, float> { }
        public class OnOTPSendingAttempt : UnityEvent<bool, float> { }

        public readonly OnLoginAttempt onLoginAttempt = new OnLoginAttempt();
        public readonly OnLogoutAttempt onLogoutAttempt = new OnLogoutAttempt();
        public readonly OnOTPSendingAttempt onOTPSendingAttempt = new OnOTPSendingAttempt();```

Is there any way how can I pass an object that is derived from UnityEvent as an argument to be invoked

[real plume]

it's my own class but i didn't do any overrides it's just a bunch of variables, most arbitrary for now

[hearty venture]

i mean instead of doing 3-4 Debug.Log in a row do something like

Debug.Log($"{cellDict[tileLocation]} - {cellDict[tileLocation] == null} - {cellDict[tileLocation].Position}");

that way you make sure that your logs aren't coming from different instaces, positions on the array etc

[gaunt spoke]

is it possible that the comparison to null actually creates the entry and then your second log returns the position due to a default position value or smthing ?

[hearty venture]

it is possible if both CellData and CellData.Position are structs

[flint wraith]

i think problem is that CellData was inheriting MonoBehaviour

so == null was checking does it have gameObject

we are testing that now

[hearty venture]

then again if they would be structs wont return true on == null i think

[flint wraith]

this is class

so new CellData(); doesnt create object

[sly grove]

Good God use a local variable

[gaunt spoke]

ah you are doing new() on a monobehaviour, it has never done any good

[sly grove]

CellData cell = new CellData();
cellDict.Add(tileLocation, cell)
cell.Index = ...
cell.Active = false;```
Etc.

[pliant crest]

nono

[sly grove]

But yeah new with MB is no good

[pliant crest]

var cell = new CellData()
{
  Index = ...,
  etc...
};
cellDict[tileLocation] = cell;

[sly grove]

Either way

Use a variable

Don't you get tired of writing out cellDict[tileLocation] 80 times?

[pliant crest]

.Add might be viable if you care about collision

as this just inserts or overrides cellDict[tileLocation] = cell;

[flint wraith]

we were testing lots of stuff...

this part not important right now

it was variable at first

[sly grove]

Making a variable would never have been the problem

[pliant crest]

(ps if you are lazy and need to show a whole object in debug you can just convert it to json)

or you know use a breakpoint

[rugged radish]

https://blog.unity.com/technology/custom-operator-should-we-keep-it
If that class is a MonoBehaviour, looks like the issue does lie in a custom == operator
even if you didn't write it yourself

[pliant crest]

you could technically

if (object is null)

which bypasses that

[rugged radish]

even is null behaves weird in that case

[pliant crest]

probably

it shouldn't be a monob in the first place

[flint wraith]

but CellData never should have been monobehaviour as it only stores data about cell

[pliant crest]

the monob class should be separate from the data class

[flint wraith]

which is in dictionary

[pliant crest]

whats the standard for hiding an object that needs to be hidden unhidden alot?

[hearty venture]

@flint wraith just noticed that ur snippet of CellData didn't contain the declaration for Position

[flint wraith]

its much longer

and code is not mine

trying to help aes0p

[upbeat path]

depends on your use case, you can toggle the SetActive on the gameobject or toggle the enabled on the Renderer

[pliant crest]

theres no performance issue on set active?

i remember vaguely when i was doing unity in the past it was a bad idea to spam this thing

[upbeat path]

there is a performance cost for everything, you need to see if that is worth paying in your particular case

[pliant crest]

welp

i guess i'm gonna cheat

and throw it out of bounds then

thou might be the same as disabling the renderer hmm

[hearty venture]

@real plume in my experience issues like this usually mean that the Debug.Logs are coming from different places/instances/places in loops hence my suggestion on placing all the info in one Debug.Log, and you should fix the new CellData() issue mentioned by others, it can definitely cause weirdness, either use AddComponent instead or (temporarily) make it so doesn't extend MonoBehaviour

[devout hare]

There's no point in trying the roundabout ways before measuring the "correct" way

[flint wraith]

Is it really that impactful? make it changeable easily. at end of project if causes lots of slowdown i would then look into it and optimize. seems like that is optimization that doesnt mean much

[real plume]

thank you. i apologize for dipping in and out, i'm in a thread w/ someone and we're trying a couple other things

[rain flicker]

Hey guys! I asked a question on StackOverflow and thought you might have some insight about my issue
https://stackoverflow.com/q/73895019/9985392

Hope it's not against rules to post a link like that 😄

[flint wraith]

class that should change it should inherit scriptable object you described
in so make getter and setter functions where setter is protected while getter is public

[rain flicker]

So what you are saying is that I should have a SO:

public class HealthSO: ScriptableObject {
   [ReadOnly]
   public float health {get; protected set;}
}

and another SO:

public class HealthSetterSO: HealthSO {
  public void SetHealth(float value) {
    base.health = value;
  }
}

Like so?

[flint wraith]

yeah

dont know what [ReadOnly] means

but that code should work

you can try now creating third script and see what you can access and what you can change

[gentle topaz]

To me, that looks like a normal get / set property with extra steps, but maybe I'm missing something

[flint wraith]

yeah but that was question

[rain flicker]

[ReadOnly] mens that this value cannot be changed from editor

But this doesn't really fix my issue. I want to block the possibility of changing this value at all from other components other than the "owner"

[flint wraith]

well value now cant be changed except from HealthSetterSO script or HealthSO

[rain flicker]

But you could reference HealthSetterSO instead of HealthSO

[flint wraith]

new script shouldnt be able to change it except through HealthSetterSO

[rain flicker]

And still get away with changing this value

[flint wraith]

then remove sethealth from HealthSetterSO

[gentle topaz]

What you want is basically impossible

[hearty venture]

The pattern i use is make a public propery with getter only and a serialized private field with [ReadOnly]

[gentle topaz]

At least, in any sensible way

You want to be able to change it externally, but only from some one unrelated script

[rain flicker]

I wouldn't be asking about it if it was easy xd

[flint wraith]

honestly just have private float health
with public get and set

that way you know only setter is changing value

[gentle topaz]

They literally want it to be impossible to change the value, like imagine a coder was actively trying to change it. They should not be able to.

[rain flicker]

That's the goal, to make it impossible for other members of the team to change it

Or at least make it very hard

[flint wraith]

think its not smart and possible.
you can make it const or readonly that way it cant be change but why make health readonly

or as i said, make health private and have public getter and setter that way only setter changes values

[rain flicker]

Well, I think that it would be good for only one component like HealthController to change this value

[flint wraith]

well then as i said, make health setter protected

[rain flicker]

I expressed myself incorrectly

[flint wraith]

and HealthController inherit HealthSO

[rain flicker]

It should be possible to change this value only from one MonoBehaviour

[gaunt spoke]

I guess you can use an interface like IHealthSetter and pass the setter object as a parameter and check in the set if the setter has the IHealthSetter interface, if yes, accept the change, but tbh I would just let the other script change the health if they want, its too muc hwork

[flint wraith]

then only healthcontroller can change it

[real plume]

we got it solved. i don't fully understand it but basically the class wasn't working right. i had to copy paste the code to a new file and it worked.

[rain flicker]

But I don't want the HealthController to be a SO

[flint wraith]

then cant help you

[rain flicker]

This could work yes, I also thought about passing an owner object and checking with each set if this is the owner

[flint wraith]

i mean part of your question is, is this good practice, honestly no

[rain flicker]

But there are ways to cheat it

[flint wraith]

bigger projects rely on readability, this wont help it

[pliant crest]

cheat + good practice = ...

[rain flicker]

Is it a good practice to allow any UI script to change an important value?

[pliant crest]

not enough context

answer unknown

like the hell is an important value

I would like to avoid a situation where a HealthBar has the ability to change player's health

[pliant crest]

player should change players health

something like

[rain flicker]

Exactly

[pliant crest]

playerInstance.TakeDamage(someDamage)

[flint wraith]

why would you cheat yourself? and why not have HealthController as SO?
What you are asking requires it to be that way, if you want just to read value you pass HealthSO if you want to chanage and read, you pass HealthController
to UI elements you pass HealthSO

[rain flicker]

But I would like to pass the current value of player's health to the UI script via SO

[pliant crest]

wait no

that doesn't make any sense

[rain flicker]

It's not only myself, there are other people working on this project

[pliant crest]

scriptable objects are for immutable data

just say you can't do that

and move on

like it makes no sense to

[rain flicker]

What do you mean immutable? You can totally change values in a SO

[pliant crest]

just because you can

doesn't mean you should

atleast during runtime

whats the benefit of doing this anyway?

[flint wraith]

As I said, You make variable private and setter public, if there is case that someone is changing health and you dont know where from. you add debug.log to setter and it show you callstack, shows where from is called

[pliant crest]

you have an additional middle man for no reason

[lament salmon]

everyone keeps saying this, but why not?

[rain flicker]

Decoupling data from logic

Connecting different systems through editor

There are a lot of fancy tricks that you can do with SO

And they are great

[pliant crest]

it sounds like you want to fake ECS

[pliant crest]

theres some weird things that happens to it

like if you change a value

its persisted

you don't get a base version of it again

[rain flicker]

That's just something that you have to remember about

[pliant crest]

yeah you are retrofitting something to your needs

[rain flicker]

You could save those values in a file and load them back

[obsidian glade]

using SO's for dynamic runtime data is just an unnecessary can of worms - their behaviour changes between editor and builds, in the editor they can persist between plays, can be overwritten, and wont function that way during a build. If you're using them during runtime they don't really do anything that a normal class wouldn't

[pliant crest]

just use ECS if you want to do decoupling of data

the argument is fine if you do it for everything

[lament salmon]

ah so the values don't persist at runtime?

[pliant crest]

instead of just one thing

like i'm all for decoupling of data

just not like this

[rain flicker]

It's not possible to do that at this stage of development :<

[pliant crest]

sadge

[obsidian glade]

with a build your SO's wont just magically save with runtime data between sessions, they will reset if you restart the program

[pliant crest]

theres just lots of edge cases you gotta remember basically

[rain flicker]

I think that those are just the two xd

[pliant crest]

fair

i actually can't think of another

(i don't use SO's myself)

well thats a lie

this project right now is the first time i used them

[lament salmon]

stop shitting on SO's just because you heard they are bad lol

theyre really good for shared data

[pliant crest]

i didn't hear they are bad thou O.o

i just never needed to template data before

[flint wraith]

just a question, why would you be worried others would tamper with hp?

unity is not for building large MMOs

where that would be concern

[pliant crest]

how would using SOs prevent that?

[rain flicker]

Thanks for the discussion guys I've got to warp up

[rain flicker]

I just wanted to use them to connect UI with a system that controls the health

https://stackoverflow.com/questions/73895019/data-safety-in-scriptable-object-based-architecture

[pliant crest]

oh

so the problem is in a team of developers

[flint wraith]

wasnt that what i was saying?

[pliant crest]

you want to stop others from accidentally setting variables on this SO

[rain flicker]

Yes it is

[rain flicker]

Exactly

[gaunt spoke]

I also agree that you should not worry about other developer setting the health, just write in the doc of your system smthing like don't set this value yourself thats it

[pliant crest]

no i agree

[rain flicker]

Maybe that's the way to go

[pliant crest]

this makes sense as a worry

you shouldn't be allowed to access something if you aren't suppose to be able to set it

[rain flicker]

But we have an active discussion about this in our team

[gentle topaz]

I feel like accidentally changing health would be quite the obvious bug

[rain flicker]

And I just wanted to use some of the internet's collective knowledge 😄

[lament salmon]

I also never quite understood, do people in programmer teams just change random values for the sake of it? And then they have to be made inaccessible 😆

[hearty venture]

yes xD

[pliant crest]

its more about not knowing you aren't allowed to

documentation can only be enforced if you read it

[rain flicker]

Yes, that's true

[pliant crest]

like imagine instead of a group of 5 people

you have a group of 100 people

propagating changes like these is dangerous

then again

[gaunt spoke]

and for SO runtime data you can use the NonSerialized attribute to ensure the value gets reset each time you press play and avoid magic values like in an actual build

[pliant crest]

i wouldn't use scriptable object

[rain flicker]

If we live the possibility someday someone might change it

[pliant crest]

why not just some data class?

[rain flicker]

You can't pass those to prefabs

[gaunt spoke]

because he wants to inject the health via the inspector I guess

[rain flicker]

yup

[pliant crest]

well okay...i was about to say

yes you can

but sure not through editor

[lament salmon]

a scriptable object can just hold that data class

to me its a container

[flint wraith]

SO are great for creating templates for stuff like starting gear for player

[pliant crest]

fair that makes sense

[pliant crest]

this isn't about templating thou

there is no template here

[flint wraith]

i would use player class to store actual health

but structure of code is really dependant on project and this is just bunch of bullshit

[pliant crest]

this still runs the risk of them replacing the reference

but i can't think of how to protect from that anyway

the player class would be the only one that can expose anything at this point

and everything needs to be a backing field behind that

[jolly token]

I accept anyone’s contribution on https://github.com/cathei/AntiScriptableObjectArchitecture 😄

[rain flicker]

O wow

[jolly token]

I should work on it more, been busy on other things

[rain flicker]

This might be usefully for us right now

Thanks

[muted urchin]

Hello everyone, does anyone know if is it possible to somehow see Debug.Log messages on a build? Or maybe even start the application using Windows command prompt and use Console.Write() to show messages at runtime in the console?

[frail kestrel]

Its always visable, hidden in %appdata%

AppData\LocalLow\project creator name\project name

It has an "output_log.txt"

[pliant crest]

could also technically just have a debug window

in game

[muted urchin]

Yeah, i know, but maybe is a little bit unconfortable ... is there some kind of alternative to see at runtime what is happening?

[pliant crest]

and reroute all your debug.logs to a singleton that switches between debug.log and that debug console output depending on build (or use preprocessor directives if they are allowed in unity)

[muted urchin]

That's interesting

As far as you know, however, is it possible to use the windows console to debug the build?

[pliant crest]

try google, i have no idea

[muted urchin]

Okok thanks 🙂

[jolly token]

https://github.com/SpaceMadness/lunar-unity-console
This is for mobile but you can see how they implemented

[flint wraith]

built application displays there?

[frail kestrel]

Yeah, I think any Unity application writes there.

[flint wraith]

oooh nice, i have always been using custom output hahahahhaha

thanks man

[frail kestrel]

No worries man 😎

[undone coral]

you can't use the windows console to debug the build

you can start with -logFile log.txt and tail the file path you provide

[jolly token]

In a nutshell use Application.logMessageReceived/logMessageReceivedThreaded and write to own log console

[undone coral]

so you would do

C:\Player\player.exe -logFile C:\Player\log.txt

that's it

does that make sense?

you cannot make unity on windows print out to the console window, period full stop. on all other platforms, you can pass -logFile -

[undone coral]

when your colleagues have access to the source code and they are modifying it in Unity, access keywords like public and private are as good as the documentation gets for how a variable should be modified. if someone who can update your source code (i.e. a programmer colleague of yours) wants to modify a variable, they can. they can always change whatever you wrote. so i wouldn't get too hung up on it

That said you should not be using scriptable objects at all

[muted urchin]

Yeah i can definitely agree

[hearty venture]

I'm sort off getting around that particular problem by making our internal framework in to a upm package

I mean they can still do it, it's just harder xD

[vivid shuttle]

Anyone have an idea how to make a dropdown list of strings in unity code? Like if I have a collection of types for powers (ice, fire, rock) but I want to select them in the inspector?

[jolly token]

Use enum?

Otherwise you'll have to do with custom inspector/property drawer

[vivid shuttle]

Is there a specific way to be able to see it? Like code wise? I have it as a public.

Oh wait-

I think I found it...?

[jolly token]

I don't understand your statement and not sure if this is advanced code question.
In any case you want to be more flexible than enum then you should use this
https://dbrizov.github.io/na-docs/attributes/drawer_attributes/dropdown.html

[vivid shuttle]

I figured it out.

I was trying to make a drop down. Not sure what was supposed to go where.

Sorry to bother anyone if I did.

Holy C > all other languages

[flint wraith]

you sure?

i can prove there are better languages

Hello, any idea why Material.HasProperty(int nameID) is returning true on the Standard shader for a property it doesn't have?
Im checking as follows:

}```
Any help is appreciated

Is there a way to await for an already-running UniTask to finish?

E.g.:

Start my first UniTask
Don't immediately await for that UniTask to finish
If that UniTask is still running at some uncertain point in time later on, await for it to finish

[sly grove]

Can't you await it at any point?

just save the task in a variable

[fresh salmon]

Yeah save the task itself in a variable

UniTask<int> whateverTask = WhateverAsync();
// .. other code
await whateverTask;

[placid jacinth]

Will try that, thank you both :)

I am guessing that I receive this error because the UniTask is not a UniTaskVoid and returns a Vector2?

oh wait

Ok so I don't await it at that point in the code, I await it afterwards
How would I go about accessing the return value?

[jolly token]

You can still do var result = await savedTask;

Just use UniTask<TReturn>

[placid jacinth]

Ah yes I think I see, like this

[jolly token]

Yes

[placid jacinth]

Thanks :)

[undone coral]

use var

[undone coral]

@placid jacinth do this

[placid jacinth]

Ok, can I ask what the benefit of it being a var is?

[austere jewel]

There is no benefit. You don't need to cache the task before awaiting it though, you can just get the Vector2 on one line by awaiting

[placid jacinth]

Aha I see now, thanks for the tip guys :D

[placid jacinth]

Ok I'll throw one more out there before I go to bed - I can't seem to call the function? I must have missed something but I'm clueless as to why I'm getting a conversion error

huh, that's a strange solve
I will test it to see if the entire thing works, but I changed the library method from a UniTaskVoid to a UniTask and now it provides no error

[jolly token]

UniTaskVoid is equivalent to async void. It's fire-and-forget. You cannot await it.

[placid jacinth]

Thanks, that makes a lot more sense

[thick cipher]

Anyone know why an API connection does not work on Android? I connected to APIs and on PC it works perfectly fine but on android I cant establish a connection. I use the UnityWebRequest stuff

should I just try it with native C# HTTPClient ?

[jolly token]

They both should work

Did you see logs from android?

[thick cipher]

not yet actually, was just hoping someone might have a quick idea. Ill check the logs when Im back from work

[undone coral]

what are the first 5 characters of the URL you are trying to access, and what are the last 3 characters of the domain name in it?

you can also paste in the whole URL if it's not sensitive

[thick cipher]

"http://api.voicerss.org/?key={key}&hl=en-us&b64=false&src={audioText}" for TTS and https://opentdb.com/api.php?amount=10&difficulty=hard to generate questions

[undone coral]

okay

so i assume the first one is busted

do you know if the second one is busted?

[thick cipher]

it should not be as the operation to get data actually finishes

[undone coral]

you don't know if it is or it isn't yet

on android

[thick cipher]

Ill get back to you guys tomorrow, I need those logs lol

[undone coral]

the second one will definitely work

[thick cipher]

the only thing I read was that some people had problems with giving their app access to the internet

[undone coral]

i am trying to find a definitive answer, but try changing the URL to https in the first URL

[thick cipher]

will do, thank you. I dont give you much to work with haha. Sorry im a beginner at best ^^

ill tell you if it works ❤️

[undone coral]

aight

[thick cipher]

Found the error

really dumb stuff on my part

I had this line within my code: File.WriteAllText("C:/C#Test/quizText.txt", answerText);

both APIs work

[hollow prairie]

whenever i instantiate my prefab from my assetbundle it just appears black
its not a material issue its the shader, it says its loaded but it only appears black until i change it

left is the prefab i made the bundle with
right is loaded from the assetbundle

what the heck do i do

[sly grove]

No idea but this is a #archived-shaders or #🔀┃art-asset-workflow or #archived-lighting question

[jovial totem]

I have an odd question. If I wanted to extend the animator to be able to change the animation curves and use other interpolation types than easing, how would I do that? They are written in C++ so I can't exactly change the code myself.

[sly grove]

You can already change the easing curves in the animator

https://docs.unity3d.com/2019.1/Documentation/Manual/TimelineEasingClips.html

[jovial totem]

I meant for an animator and animation clips, so I can change the curves in the animation clip's interpolation type from a script, like to bounce or whatever

[sly grove]

wdym by "animation clip interpolation type"?

[jovial totem]

In animation, there are multiple kinds of tweening/interpolation- Linear, easing, bouncing, cubic, etc etc

the animator only seems to let me have linear and easing

[sly grove]

which part of the animator you're talking about is what I'm asking though

[jovial totem]

like, animation clips, not the sequence timeline or whatever it is

[sly grove]

where on an animation clip is an interpolation type?

isn't that all just determined by the curves?

[jovial totem]

Exactly

Is there a way I can like… change the sampler, or extend the animation clip, that would allow me to do that

Determine how the curves look

Rather than just being bezier

[sly grove]

don't think so. It uses AnimationCurve which isn't exactly set up to be inherited/overridden or anything:
https://github.com/Unity-Technologies/UnityCsReference/blob/master/Runtime/Export/Animation/AnimationCurve.bindings.cs

you can of course programmatically create the curve

[jovial totem]

Yeah that’s what I saw… darn.

[sly grove]

trying to figure out what you're wanting to accomplish

[jovial totem]

I could. But the animator automatically uses the curves

[sly grove]

What can't you do with the bezier curves

[kindred tusk]

You can edit the curves so they have hard corners

[jovial totem]

So. Say I have an animation of a character turning to the left. It has a smooth ease in and out between key frames. Now, if that character is scared, I want to set that curve from script to be more jittery, like an old Mickey Mouse cartoon. Or like exaggerate the motions

[kindred tusk]

Right click on the node and change its tangent type

[kindred tusk]

I would just use a looping shake tween

But if you want to hand author it, you can use animation layers

Make them additive

So make a jitter animation and put it on an additive layer

[jovial totem]

Nah, I want to do it procedurally.

[jovial totem]

What is that

[sly grove]

this can all be done with the curves

by setting tangents etc

[jovial totem]

How so?

Can I do that from script?

[kindred tusk]

A tween? It's a kind of simple programmatic animation. DOTween is the library that most people use these days

But that will shake the whole model

[jovial totem]

Yeah I was thinking of using DOTween but I wasn’t sure how that would fit into the system

[sly grove]

yes

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

you can set the tangents to whatever you want

[jovial totem]

The thing is I suppose I could make my own animation system (because the regular animation system is lacking in what I want it to do) because it's basically just sampling points along a curve but it also does fancy stuff like retargeting, which I'm not at all comfortable doing.

I could use IK rigs for retargeting (which is kind of my eventual goal) but that might be too daunting of a task

[jovial totem]

playables looks kind of promising actually

@trail cloak I think we will need some more info like code from Common.SceneDirector:SetWorldOverlay, and possibly the value of the arguments its getting

[trail cloak]

Sure

This api works fine under all other scenario though

        public void SetWorldOverlay(GameObject overlayGameObject, Vector2 worldPosition, string label, float transitionDuration, bool uiMode, bool tutorialMode)

            }
        }

The game crashes on Instantiate

This is the prefab I'm instantiating

[long ivy]

your stacktrace looks fishy to me. GameTimeManager is a MonoBehaviour, and that's the normal Unity-called Update right? You aren't doing something off the main thread or doing some kind of native interop?

[trail cloak]

That's just unity update

relax

I'm using that to ensure timeline goes exactly one cell each frame

[flint sage]

So you generate a number between 0 and the sum of all rarities (doesn't have to be % based), then if it's in the first 20 then it's rare, the next 30, it's uncommon, the last 50, it's common

You misunderstood

you literally write a loop that goes through your drop rates and adds them together until you reached the number you generated

int target = 67 (random)
int sum;
for (drop in droprates)
{
  sum += drop.perc;
  if (sum > target)
    return drop
}

[viral edge]

Ahh the sum is what I'm missing, makes perfect sense now. Add it up as I go through each rarity until I hit the target.

Thanks Navi!

cs

    public void MakeRequest<T>(VRCloudRequestBase vrCloudrequest, UnityEvent<VRCloudResponseBase> callback) where T : VRCloudResponseBase, new()
        {
            if (vrCloudrequest is IPost)
            {
                var request = new HTTPRequest(new Uri(baseURL + vrCloudrequest.Endpoint), methodType: HTTPMethods.Post, callback: OnPostRequestFinished);
                request.Send();
            }
        }```

This generic function has a "T" value. Is it possible to pass the "T" value to "OnPostRequestFinished" callback of the HTTPRequest?

[tribal ridge]

I got a simple question about the job system

Basically can I do the following:

    struct TestJob : IJobParallelFor
    {
        public NativeArray<byte> type;

        public void Execute(int index)
        {

            if (type[index] == 1)
            {
                if (type[2] == 1) // CAN I DO THIS??
                {
                    // do something 
                }
        }

    }```

or is that not allowed?

[jolly token]

I don’t see anywhere you are actually using type T. Generic parameter is not any value and it is just a type.

[mint sleet]

I want to pass the T as an argument to a callback method.

But its not a reference type so, it does not make sense to me if there is a way

But you never know if there is a way. That is why I asked

[fresh salmon]

You can't, as HttpRequest isn't generic, nor its callback property.
You'll have to make another lambda to use the generic parameter, and make OnPostRequestFnished generic itself:

callback: (...) => OnPostRequestFinished<T>(...)

[hushed moth]

Do you guys have some idea what am I missing?

[fresh salmon]

I saw the question yesterday and couldn't answer
You tell us what's missing. Do you get errors? Post them. Debug your issue, this is #archived-code-advanced

[hushed moth]

That is the intereresting part, no error, i just see that the image is corrupted and the game is lagging each time stronger when i call the changeURL. In the logs i can see that the close, dispose etc run well

[fresh salmon]

See that's some info that should have been included in the original post

Also I see you call OnDestroy, Awake, Start manually from ChangeURL? What?

These are Unity methods and are called by Unity. These shouldn't be ran manually

Either way open up the profiler, enable deep profiling and check out what makes the game lag

[hushed moth]

is there better method to change the source? I tought that i close the current and open the new one

[fresh salmon]

Can't answer that, didn't use WebRTC

Their docs probably have the answer, or at least best practices

But if that thing is used to connect to a server then yes, I would get rid of the old instance and create a brand new one when changing the URL

[mint sleet]

{"data":null,"success":true,"message":"The password has been send to the phone number"}```

  var ob = JsonUtility.FromJson<T>(request.downloadHandler.text);```

        [Serializable] public class OTPResult : VRCloudResponseBase
        {
            public string Data { get; set; }
            public bool Success { get; set; }
            public string Message { get; set; }
        }```

Hello. The incoming JSON has "Data" field as null object.

But in my class it is string.

Maybe that is because this FromJson can not convert it to an object.

where am I missing? The generic "T" is OTPResult class in this case.

[compact ingot]

What is the problem? Seems like your json field names don’t match the c# names

[mint sleet]

the ob comes null

let me share ss to make it more clear. @compact ingot

[flat marsh]

Well it's null in the json?

What do you expect it to be?

[mint sleet]

I want to convert the string coming from the server to a unity object

I marked Data field in OtpResult as nullable

it did not work either.

[flat marsh]

But there is no string in the data field

It's missing the ""

[sly grove]

Unity cannot serialize/deserialize properties

these are properties not fields

JsonUtility only serializes fields

[compact ingot]

Also Your property names in c# are wrong they need to match the json exactly

[sly grove]

also there are no fields 😉

[mint sleet]

what is difference between field and property 🙂

[sly grove]

Now if you want to get cute about it you can do this:

[field:SerializeField] public string data { get; set; }``` and keep your properties.

[sly grove]

properties are a pair of functions to get and set data

in this case you have an "auto implemented" property, so there is a magic field C# compiler creates for you that your functions are getting and setting

fields are actual, normal variables that actually hold information

[sly grove]

If you do it this way, Unity will know to serialize the "magic invisible field" behind this property

but normally you'd just do this:

        [Serializable] public class OTPResult : VRCloudResponseBase
        {
            public string Data;
            public bool Success;
            public string Message;
        }```

now those are fields, not properties

[mint sleet]

ohh! what a mistake.

@sly grove thanks mate

[compact ingot]

Still wrong names

[mint sleet]

what do you mean wrong names ?

[sly grove]

yes they are case sensitive too I believe

[mint sleet]

oh! that sucks. I must change the backend responses for that.

[sly grove]

honestly all these little weird restrictions are why I prefer to use NewtonSoft JSON instead of JsonUtility

much more configurable

[mint sleet]

I've just started interpreter library for the backend.

[sly grove]

so you can keep your capitalized property names and serialize as something else with an attribute like [JsonProperty(PropertyName="data")]

[mint sleet]

nothing to lose to jump into newtonsoft then.

Hello, my Unity build crashes on MACOS on launch (Intel64), does anyone had a similar issue?

Unity Version is 2021.3.5f1c1

[fiery horizon]

anyone here used the new openID connect with the latest unity version? I got an error

WebRequestException: {"title":"PERMISSION_DENIED","detail":"validation failed","details":[],"status":401}

[undone coral]

which apple device is this?

[trail cloak]

This is my apple vm

[undone coral]

well there you go

that's what i thought

[trail cloak]

But the crashes also happend on actual apple device

Let me talk to the end user

[undone coral]

this particular stack isn't saying anything

[trail cloak]

True

It's same both on Mono and IL2CPP

[undone coral]

you can try to reproduce the crash on a development build, i forget where the standalone player symbols are

but i doubt that stack is going to say anything interesting

[trail cloak]

But unity editor do run on mac vm

[undone coral]

it says bad access right?

or

no

it's not

i mean

it's weird that you have audio calls on the main thread

do you use OnAudioFilterRead

[trail cloak]

No I didn't...

[undone coral]

i think that's a red herring

really hard to say. this might be worthy of sending a bug to unity

[trail cloak]

That's too bad if true...

just got the crash log from the user

May be I should't build the project using VM.... but it works in 2019.4 LTS

[kindred tusk]

It's a pain testing mac without an actual mac lying around

[trail cloak]

Just got one

Although it's ancient

[kindred tusk]

Yes, I just discovered that I can't update mine to latest OS

Which is a pain

[trail cloak]

Oh no

[hard osprey]

Can somebody help me with bundles and execution order? because scripts from bundles dont have correct order to execute. How i can execute scripts in bundle object by default order in project settings?

[undone coral]

bundles?

[undone coral]

what is the actual exception?

this is just the stack

it should say something like SIG BAD ACCESS or whatever

is this on launch?

[hard osprey]

AssetBundles

[hard osprey]

u know what is it Bundle? and scripts inside it?

[hard osprey]

Simple question why scripts inside bundle not work as in custom order execution in project settings that all.

[undone coral]

there is a lot of writing online about the limitations and challenges of scripts in asset bundles

are you trying to say you've authored a script that does not exist in the built player, and you're delivering it in an asset bundle?

you also shouldn't rely on order of execution for the most part for anything

even if there is a way to configure it

i am not sure if unity built players respect the attribute that allows you to set an order

[hard osprey]

If you know how to work with inverse kinematics, animator and a physical doll, without script execution order! You will receive $1,000,000

[undone coral]

hmm

what is your objective?

like what kind of game is this and why do you need to bundle characters?

[hard osprey]

i have 1 000 000 000 characters, and i not need to store all of them in side current state of game progress

[undone coral]

i think this might be beyond my abilities i'm sorry

good luck out there

[jolly token]

You cannot put scripts in asset bundle, they are not bundled. unless you manually do dynamic assembly loading stuff

[hard osprey]

i dont put scripts inside bundle. they just have data of the script. Code exists only on client not in bundle. why u not know about this, u just learning unity?

[hard osprey]

this is advanced code group?

[jolly token]

scripts from bundles dont have correct order to execute. How i can execute scripts in bundle object by default order in project settings?
Read what you said

[jolly token]

Exactly. if you are advanced you wouldn't say "scripts from bundles" or "scripts in bundle object"

Go #💻┃code-beginner

[hard osprey]

First learn how scripts work in the bundles.

[jolly token]

I know well enough 🙂 You are the one having problem with it, not me

[hard osprey]

I need help in unity3d.

Create object, drop on script -> create prefab and bundle of this prefab -> load the bundle in play -> get info about the scrip and how it is work.

[undone coral]

@hard osprey try in #💻┃code-beginner and talk about your game as it is

[hard osprey]

@undone coral my knowledge does not stand still like yours

@undone coral gloss dont worry u banned

[jolly token]

You have such a low chance to get help with that attitude, lol

[hard osprey]

yes but i dont wont holly war here 😭

[hard osprey]

i just create manager of script execution order at this moment, before fix this bug. For custom Update, LateUpdate and FixedUpdate by extension interface

[trail cloak]

There is not exception, which is weird

I moved the project to an actual Mac PC then build & run it

This is the log

[placid jacinth]

Following on from my inquisitions yesterday:
Does anyone know if there is an equivalent or a way to make a while loop work with the UniTask system?
I can't mentally grasp how to combine it with the process of awaiting functions

I'm pretty sure what I'm asking for is a way to await a while loop's completion

For further context, I am trying to move an object to a position over a duration of time, if there is an alternate way I would gladly use it over a loop :)

[gentle topaz]

ever looked into DOTween? UniTask has support for it

[midnight violet]

Does it give you any error in editor when running. Or. high profile spikes?

[placid jacinth]

I have heard the name, I'll look into it and see if that can do what I need, thanks :)

[midnight violet]

If you dont need a big tweening library, dont go dotween for every single movement. My personal opinion

If you need a lot of animation of a lot of different objects, dotween might be worth a short

[midnight violet]

What is your issue with waiting for a while loop there? Await just waits for whatever you throw at it

[placid jacinth]

Well my question is simply how to go about doing it?
I haven't found any forum posts, or anything on the GitHub page, and I'm having a hard time understanding how I can await a loop as to speak

[chilly nymph]

Tasks themselves work fine for this. Is there a gain to uni task that you need?

[placid jacinth]

Yes, it's designed to work with Unity

[gentle topaz]

private async UniTask MoveObjectToPosAsync()
{
  var t = 0f;
  var duration = 5f;
  var startPos = Vector3.zero;
  var endPos = Vector3.one;

  while (t < duration)
  {
    t += Time.deltaTime;
                
    var newPos = Vector3.Lerp(startPos, endPos, t / duration);
    // use newPos to do something
                
    await UniTask.Yield();
  }
}

Seems to me like this would work just fine

[chilly nymph]

Tasks are designed to work with c# what's the gain with unitasks?

[gentle topaz]

Assuming you want it to move something over time

and you could just await the function call if you want to "await the while loop"

but you could also use async delegates, etc

[placid jacinth]

I was originally going to use tasks, I was recommended by several people in here that UniTasks would be a better solution as it is actually integrated to Unity's playerloop

[placid jacinth]

Thank you for the example, I will tailor this to what I needed, I sort of had a brain melt yesterday getting it all working lol

[chilly nymph]

I just looked into the difference it doesn't look like therrs any gain.

[midnight violet]

If unity has a native way of doing it, most of the time, 3rd party packages will just clutter up your workflow

[chilly nymph]

If anything it looks like it uses tasks under the hood.

[placid jacinth]

That's the point of it all tho

Tasks are not native to Unity

[gentle topaz]

I would have to say that UniTask does the exact opposite of "clutter up your workflow"

[placid jacinth]

they are native to C#

[gentle topaz]

it's the least boilerplate thing I can imagine

[chilly nymph]

Unitasks are a layer on top of tasks 😄

[placid jacinth]

Well I'll trust that you have more experience than me on this, so be it
I'm not that worried about bloat as of current because this is the only 3rd party package I'm currently using

[midnight violet]

So what about System.Threading.Tasks?

[chilly nymph]

If all you're doing is awaiting I would just use the task Lib.

[midnight violet]

https://learn.microsoft.com/de-de/dotnet/api/system.threading.tasks.task?view=net-6.0

Is that supported by unity?

[chilly nymph]

Await Task.yeild()

[gentle topaz]

Obviously, otherwise UniTask wouldn't be using it... But UniTask just enhances the Task system with all the bullet points mentioned in their github page.

[chilly nymph]

Unless someone else can explain what the gain from another Lib would be ( I am interested) after doing a quick look it's not doing much.

[trail cloak]

No warning, but High Profiler Spikes... let me check

[midnight violet]

Than Apple is stopping your app from allocating too much memory maybe.

[compact ingot]

unitask also gives you a better sychronisation context, makes switching between main thread and thread pool very easy during the execution of a task and provides extension methods to unify all async patterns that are commonly used in unity (coroutines, events, dotween, async/await, channels) into one API

[midnight violet]

Yeah I guess thats the point. If you need that whole async extents for events in UI and stuff, it makes sense to use it. But not just to do simple awaits. Guess its subjective to the needs of the person asking here 🙂

[midnight violet]

Good point 🙂

[gentle topaz]

I just don't get the pushback. It's fine to be skeptical, but as someone who uses it regularly, I can't see a reason not to use it. Even if you only use it in GUI, and especially with DOTween.

It's simply a good library

But yeah, subjective to the needs I suppose

[chilly nymph]

It's fine to use it, but would you use a dictionary in place of an array for storing a few enemy names?

It's knowing when to use the right tool.

[gentle topaz]

I might, if it's more convenient

[chilly nymph]

You're free to do it no one will stop you, but it's not really the best way.

[midnight violet]

I just jumped into the fun of ARCoreExtensions. Best way to have a full package to just do one job and give you a lot of bugs. Thats why I am not always a fan of 3rd party 😄

[trail cloak]

There is no memory spike though...

[midnight violet]

Does the app crash immediately on start afte rbuilding it with xcode?

[chilly nymph]

This is a great point, something that's not standard Lib is not guaranteed go be stable.

[trail cloak]

The game runs fine inside editor, it just crashes in standalone build

[chilly nymph]

Are you building on the new chip?

[trail cloak]

I did not build the app using Xcode, Unity just build it and output an .app executable, but yes, it crashes on start

[trail cloak]

No

[midnight violet]

I think unity uses xcode under the hood for it, right? Or not

[gentle topaz]

Well in my opinion the "best" way is the way that makes it easiest to code and maintain. But clearly we share different viewpoints so I don't really want to drag on the conversation

I know what you are saying though, I just don't agree.

[chilly nymph]

Experience is a great teacher. 😄

But yes that's fine.

[trail cloak]

Maybe yes? I am not familiar with the Macos pipline

[chilly nymph]

You're building a apple build without an apple?

[midnight violet]

Can you share your debug log in raw text so checkout?

[trail cloak]

Previously I'm building it on my mac VM, but now I am building though a real macbook

[trail cloak]

sure

[chilly nymph]

And what device are you trying to play on, the new chip comes into play. Make sure this isn't the issue.

https://answers.unity.com/questions/1872228/does-any-unity-editor-run-native-on-m1-macs.html

[trail cloak]

Just mentioned, it's an ancient macbook

[midnight violet]

Silicon versions are in hub already, just use them. but as it is building, I think its already working

[chilly nymph]

There's m1 and silicone.

[trail cloak]

Not apple sillicon

[midnight violet]

Oh yeah, your debug log said intel iris

[chilly nymph]

What's the build device running?

You can't run a m1 build on a silicone.

It's different arcetecture.

[trail cloak]

Here's the log

[midnight violet]

Silicon is m1

[chilly nymph]

What's the old chip?

[trail cloak]

Intel

[chilly nymph]

Can't play m1 on Intel.

😄

[trail cloak]

I know

I am build to Intel

[midnight violet]

Oh, 2015 macbook air and only 4gb of ram. you might just run out of memory

[chilly nymph]

I'm 99% sure you cannot built the old arcetecture with the new one.

All iOS apps have to be updated for the store as well.

[trail cloak]

This is my build setup

[midnight violet]

It is working ,yu can build for old and new hardware with old and new. Apple is doing a great job here also running everything on everything

[midnight violet]

Can you export the xcode project and zip and send it? I can test it

[trail cloak]

Sadly the build crashes every time, even on customers' mac

[midnight violet]

If you export xcode and throw it over, I can have a look at it @trail cloak

[trail cloak]

Let me see

[trail cloak]

Sadly I might not be able to send you the xcode project, since it contains confidential assets & code, is there documentation about testing this?

[midnight violet]

Can you send the app itself?

[trail cloak]

Oh no

Let me build with my vm

Wait, I can just build to intel64

[midnight violet]

Yeah, you might update your sdk, if you even can with that older machine

[trail cloak]

I can compile to il2cpp if I choose only Intel64, working on that

Takes forever for il2cpp compilation...

[midnight violet]

Yep, it converts to c++

On 4gb ram. Dont expect fast build times

[sullen sleet]

Hi all, I'm wondering if anyone here has any experience/resources with sending data from an android phone to unity via a USB cable?

[midnight violet]

You could use websocket or TCP/IP

@sullen sleet

[sullen sleet]

It's important that the data is sent through USB serial ports, not through anything internet related. This software will be used in real world locations that wont have internet connection

[midnight violet]

Oh, so you need wired data transfer, got it

[sullen sleet]

Yep

[midnight violet]

Well, then you gotta put yourself together your own drivers that handle your phone correctly.

Cause, USB is nothing you can easily address

[sly grove]

almost definitely something you're going to need a native plugin for

[pale pier]

Most phones have a USB Tether option, you can probably use that to establish a local network where you can send data via usual sockets.
Seems much more direct, except that you'll need to instruct the user to manually activate USB tethering.

[midnight violet]

Or you can hook into serial communication like arduino does it.

But still you would need some software on your machine that interprets the serial calls. Arduino has its chips, your unity host machine and/or android phone needs that software wise if possible

[sullen sleet]

I'll start looking into these methods. Thanks for the step in the right direction @midnight violet @sly grove @pale pier !

[midnight violet]

Dang that is long 😄

[trail cloak]

yep...

[midnight violet]

If I had a MacOS VM here, i would hand it over to you to speed it up 😄 Sadly I did not manage to run macOS on VM yet

[trail cloak]

I do have a MacOS VM for building... but after upgrade to 2021 (along with a bunch of code restructure) everything it builds start crashing

[midnight violet]

I would rather investigate in a fast VM build than that. Imagine doing changes to test and going through 30+ minutes build times

[trail cloak]

I see

Give me a sec

Wait.... can I copy .app to windows machine?

[midnight violet]

But you cant run it 😄

Windows will just open its contents

[trail cloak]

That's for sure

[trail cloak]

Sending you right now

[midnight violet]

Where, discord DM?

[trail cloak]

Oh no

I's 416MB

Google drive then

12minutes for upload

[midnight violet]

Yeah, unity is quite huge even with minimal setup

[midnight violet]

All good, I got time and fast download 😄

[trail cloak]

Sry for letting you to wait for so long

[midnight violet]

? All good. I am working on my own project besides, setting up my VM, updating steam, playing some game maybe 😄

[trail cloak]

https://drive.google.com/file/d/1aGdXgFz1fTwWINSBHatc8ZlRDKJqRwBi/view?usp=sharing

Here

[midnight violet]

It wants a code

[midnight violet]

did you get my access request

[trail cloak]

Yes, done

[midnight violet]

Cant run. Might be because I am on M1. But tthought rosetta takes care of that

[trail cloak]

And that's exactly the issue I met

I can build once more with Mac sillicon included

[midnight violet]

Well, with the xcode project I could have checked it, but with the app itself, nope

I dont get any debug logs from the build app. thats the reason

[trail cloak]

I see, let me check if there's any way to not leak the code itself

while giving you the xcode project

Debug?

[midnight violet]

It will convert it to cpp anyway. And I really do not care about your contents. Be sure, I signed enough NDAs in my life 😄

[trail cloak]

I see, which mode should I create the Xcode Project?

[midnight violet]

Go with debug, thats fine

[trail cloak]

Ok

Building...

That's fast

weird...

[midnight violet]

Its just building the xcode project, not the app itself

thats what xcode will do then

[trail cloak]

19 minutes for upload...

[midnight violet]

All good 😄

[trail cloak]

https://drive.google.com/file/d/1jjfL30Xuj5YSUhzJq4xYxI537bqhdyFm/view?usp=sharing

Here

[midnight violet]

Oh sorry, missed that

[trail cloak]

My fault.. sry for felling asleep

Done

[midnight violet]

Lets see what I get for output

[trail cloak]

Ty

[midnight violet]

Hm, did you remove something from the xcode project?

[trail cloak]

no, I didn't

[midnight violet]

Cause its missing a GameAssembly.dylib

So a full framework seems to be missing

[trail cloak]

GameAssembly.... that's the lib for user code

under il2cpp

I believe it's within the previous .app you got

[midnight violet]

Yeah there is something wrong with your project entirely 😄
error build: Command PhaseScriptExecution failed with a nonzero exit code

I would try another unity version and maybe an updated xcode version. Also use shift command k to clean build folder. That also helps sometimes. What happens if you open the xcode project and press run?

[trail cloak]

I never tried

Let me se

Oh no

I can't even install xcode on this vm

[midnight violet]

Why not? what does it say? 😄

[trail cloak]

"We cannot install Xcode on 'System', because it needs macOS v12.5 or higher version"

Guess I need a new vm for building

Maybe that explains...

I'm going to create an empty project, build it and see if it runs

If it doesn't, I probably need a newer version of MacOS

[midnight violet]

I guess so too...

Did you follow a tutorial for that macos vm?

[trail cloak]

I already forgot which on I followed..

But it's not smooth

After I create the project, it immediatly enters safe mode with compile errors

I resolved it removed 2D feature pack and visual scripting pack

Then I made a build and it runs normally....

But there are visual glitches

I think I need to get a new vm

Anyway, thanks for the help

[midnight violet]

If you already get errors when opening the project, there might be a script buggy

[undone coral]

you're an experienced developer. you know you can't send screenshots of logs.

[undone coral]

this is very strange

did you decompile a game?

[trail cloak]

I sent the log file itself later

[trail cloak]

No

This is our product

It use to work when using Unity 2019.4 LTS

After upgrading to Unity 2021.3.5f1 LTS every build on mac crashes

*Works fine in Unity Mac Editor

[west scarab]

Anyone ever had this happen? It stops me from building, not sure what is going on:
Asset has disappeared while building player to 'globalgamemanagers.assets' - path '', instancedID '-268732' UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Already tried a reimport with no success

[fickle inlet]

could someone help me with this? I am looking for the closest vector between two vectors relative to another vector, check the image please

[west scarab]

https://forum.unity.com/threads/how-do-i-find-the-closest-point-on-a-line.340058/

[sly grove]

This is just vector projection right?

Vector3.Project(c-a, b-a)

[fickle inlet]

@west scarab solution worked

[maiden turtle]

You're computing the magnitude twice, change line.Normalize() to line /= len

[inland prairie]

Hello, what is the way to initialize the variables of a ScriptableSingleton.
Thanks!

[regal olive]

When i send a request in my script and it returns JSON, how would I handle that?

[trail cloak]

You deserialize the Json and turn it into a class instance

[regal olive]

And how would i go about doing that?

i found out

[trail cloak]

Oh

[timber flame]

I have implemented a 3d A*. It is OK but there are some issues.
I do not want to let the algorithm find a path like the picture below. A path passes below another path
How can I add the limitation mentioned?
The sample path has been shown by cubes

[obsidian glade]

in your closed set you could keep track of x,z and reject any (x,*,z) as being already visited

[timber flame]

I can add the upper and lower voxels to close list when the current voxel is added to but it removes some search space

If it is your meaning

[obsidian glade]

that's true, it may be brutally inefficient but perhaps you can store the current optimal path for each node in its state and check against the entire path up to that point

not sure I have an exact answer that would definitely work and be optimal though, just throwing out ideas

[timber flame]

You say it should work?

    var currentNode = _openList.Dequeue();
                _openSet.Remove(currentNode.Point);

                _closeList.Add(currentNode.Point);
                _closeList.Add(currentNode.Point + Vector3Int.up);
                _closeList.Add(currentNode.Point + Vector3Int.down);

Maybe, my algorithm has bug because sometimes it cannot find the correct path (optimum)

Yes, I can store the current optimal path and check the condition but inefficient as you mentioned

[obsidian glade]

as you said doing that will stop the path from going underneath, but it also may remove the actual optimal path incorrectly

[timber flame]

Probably, I do not need it

[timber flame]

Yes but when one node has been chosen (remove from openset and add to closeset), it means the path is optimum to this point! isn't?

So, I can add upper and lower voxels to close list as well!

I don't know

[obsidian glade]

you may find the optimal route to a point, say (3, 1, 3), and then add (3, 0, 3) and (3, 2, 3) to the closed set - but it turns out the optimal path to your target actually goes through (3, 0, 3), you just happened to search (3, 1, 3) first - so I think you're right that it doesn't work in general, but it might work depending on the structure of your pathing/weights

[timber flame]

Yes, it should not work because I have tested

and thought maybe it is a bug

Really thanks
@obsidian glade

But it is annoying the current path should be kept and then check if the upper voxel is empty or filled :/
I want another easy solution 😦

Also, I found this problem in Dijkstra not A* but definitely it is not related

[obsidian glade]

I'd think you could include the path in the node structure, say, _openList.Add((nextNode, pathToThisNode), weight); , then when searching for adjacent nodes you can compare the path to this node and reject going underneath - I have a feeling this might blow up though

[timber flame]

So, the only way is this :/

[obsidian glade]

I'm sure someone out there has a better idea than this

[timber flame]

I have other two questions but related 🙂

Sometimes when node extension (children), they are obstacles and sometimes not.
It depends on the direction of extension and some conditions.
For example, a final node (target) should be connected to the previous one horizontally not diagonally.

In this situation, I return a giant weight for that child in gcost to prevent this node from extending. It is OK

and the last question is how I can limit the search space because the world size is large.
Therefore, it can find a path or not, it is OK.
1- Distance between source point and current node (child) and if it is greater than a threshold, add it to close list (soft condition)
2- Limit node count in open set (hard condition)

[compact ingot]

on large graphs you typically implement some sort of hierarchical A*... you might have a "overland/highway" graph that contains information about which regions are connected and a "local" graph that is used for finding the path from the closest exit of the overland graph to the actual target. This local graphy may even be dynamically generated if storing/loading a baked graph is not possible

[marble locust]

is it possible to check which file opened my game? I'm using custom file types to store 'projects/scenes'

either a path or a file name, i can't seem to figure it out

[queen orchid]

Hello does anyone know how multiple players with multiple concurrent scenes would work? I'm thinking of offloading each player to load their own scene and sort of synchronizing all the gameobjects between players of the same scene otherwise disable/delete it.
Is there any library/API that can be used apart from just disabling all previous scene stuff and loading a new scene locally and syncing it up with the network manager

[jolly token]

So I went for this approach and managed to make a type
https://github.com/cathei/Incremental

Performance seems alright, better than decimal or BigDouble in many cases

Though still wondering if there is any better algorithm/feature to calc 128 bit multiplication or division

[queen orchid]

nvm got a solution^ not needed anymore

[gusty kernel]

your pfp is so sadisfying, I'm like watching at it for 2 minutes

[regal olive]

Anyone know how to deserialize a json string and get values from it?

[pale pier]

Uhhh JsonUtility ?
https://docs.unity3d.com/ScriptReference/JsonUtility.html

[fresh salmon]

JsonUtility indeed. Create a class that "maps" the JSON string and deserialize away!

[regal olive]

may you give an example of how to use this?

I understand its JsonUtility.FromJson(string)

[pale pier]

The docs provide an example
https://docs.unity3d.com/ScriptReference/JsonUtility.FromJson.html

[regal olive]

ah ok thankyou

[arctic lake]

My game doesn't pick up my SQLite database when it's built

But it does pick it up in the editor

How do I solve this

[upbeat path]

where do you store your database?

[arctic lake]

It's in my project folder

In the same place you see Assets, Plugins

Etc.

[upbeat path]

what is your target platform?

[arctic lake]

What does that mean

I'm still new with this

[upbeat path]

what platform are you building to?

[arctic lake]

Oh

Windows

Mb

[upbeat path]

then your database needs to be in Assets/StreamingAssets for it to be included in the build

[arctic lake]

Do I need to create another folder StreamingAssets or should it already be there

[upbeat path]

you need to create

[arctic lake]

Gotcha, thanks!

One last question

Does the database I have apply to everyone else when they download
