@undone coral again I really appreciate your help and unirx suggestion. I just saw a tutorial where someone does:

        .Where(_ => Input.GetMouseDown(0))
        .Timestamp()
        .Where(x => x.Timestamp > _lastFired.AddSeconds(_fireRate))
        •Subscribe(x=>{
            weapon.Fire0);
            lastfired = x.Timestamp;
        });

Am I correct in thinking it would be more in the spirit of unirx to replace the timestamp + where with .Throttle(TimeSpan.FromSeconds(_fireRate))?

[sweet summit]

Is there a good approach for allowing any optional parameters on a method?
I have a method that has many overrides OnCallback(string callbackName) where some of the overrides include optional parameters like a byte or vector.
Would it be bad practice to do one method OnCallback(string callbackName, Object obj) with an object or something more universal?

So far ive been able to condense my needs into 5 different overrides

name,
name, byte
name, byte, vector
name, byte, vector, quaternion
name, vector

[jolly token]

It would be bad practices as you lose compile time type information and the caller cannot see what object is accepted intuitively

[sweet summit]

I see, it seems like it would be a pain to make sure the objects are valid too

[jolly token]

Just make overloads

[sweet summit]

Mmk, I think as I develop it will become clear what is needed or not.
5 doesnt seem to bad, adding more doesnt seem to bad either

[jolly token]

For things like Vector or byte you could have optional parameter with default

[sweet summit]

Yeah my first implementation was only name and an optional byte=0

This is being used for an ability system to allow some things to be handled by a networked AbilityManager script

like OnCallback("SpawnWeaponEffect", 0) which invokes on slot 0

not every ability needs every overload though, just override it as needed

[jolly token]

I'd prefer to hide something dirty like that with source generation or such

[sweet summit]

What do you mean?

[jolly token]

So business code just uses compile time types safely

[sweet summit]

So something like an enum or constant rather than string literal?

[jolly token]

Like automatically generated stub

I don't exactly know what your setup is but you could hide that you are using string with generated code

[sweet summit]

I see what you mean

Since currently all the callbacks are using method names i'm basically just using nameOf

then a switch on the invoking side to check the string

There were a few cases I wrapped the callback so that i dont have to send an extra string over the network

[undone coral]

well the problem with what this is doing is that it's wrong lol

that's not how firing works

for most games

it wouldn't be right to throttle the input

it just speaks to how idiosyncratic most inputs are

i don't htink that tutorial is very good

the plus side of unirx though is that it was extremely easy to comprehend what would happen / what the code is trying to do

because it's so succinct

and that's why it was obvious to me it was wrong in terms of delivering the wrong user experience

it is almost a throttle*

[tropic stag]

out of curiosity: how so? (but the original example with timestamp + where() was wrong in the same way? meaning a throttle provides the same behaviour?)

[undone coral]

in an fps it's really this - https://reactivex.io/documentation/operators/sample.html

most of the time it's a "ThrottleFirst"

for lots of weapons it's like there's a short cooldown after you fire successfully during which another input will NOT schedule a second firing

e.g. for weapons with very slow firing rates

[tropic stag]

I'm going to have to read both this and throttle docs, cause I though what you just described (cooldown after fire) was a throttle...

[undone coral]

unfortunately in c#, .Throttle(TimeSpan.FromSeconds(_fireRate)) is debounce

@tropic stag https://github.com/dotnet/reactive/issues/1471

😦

sorry

that's just how it goes

unirx has throttlefirst though

[waxen sinew]

#💻┃code-beginner message i hope that would be the right place for that since the issue seems pretty complex and hopefully someone can come up with any solution to this, id be very thankful for any ideas. more info in the thread

[real blaze]

hi, does anyone have an idea to what this error might be pointing to? surely it's not trying to strip mscorlib. ( right? 😅)

• this error is a IL2CPP build error, and to my knowledge, happens not during the stripping but during the c++ conversion

here's the log in text, if the image is too tiny

System.InvalidOperationException: One or more shared enum types could not be found.  Was the embedded mscorlib.xml file present when UnityLinker Ran?
Missing types were
[System.SByte, ]
[System.Int16, ]
[System.Int32, ]
[System.Int64, ]
[System.Byte, ]
[System.UInt16, ]
[System.UInt32, ]
[System.UInt64, ]

[flint sage]

That sounds like a bug in Unity

[real blaze]

it's LTS

2021.2.13f1

[flint sage]

Do you have that file that lets you ignore specific classes/namespaces?

I forgot what it is called

And what happens if you disable stripping completely?

[real blaze]

the linker xml ?

[flint sage]

Yeah

[real blaze]

nope we're avoiding that altogether

the stripping is set to minimal already

but if that is the case and it has stripped mscorlib, then, I'll have to write this I guess?

<linker>
    <assembly fullname="mscorlib" preserve="all"/>
</linker>

put as link.xml in the Assets folder, that is

(didn't work)

changing the project to 2021.3.8.f1 to test if it works

[flint sage]

Does it also break on different machines?

[real blaze]

yes, exact same error in my colleague's machine

[flint sage]

What about in a new project?

[real blaze]

it's the our packages in use

wait, let me create a thread for it

Unity IL2CPP Linux Server build issue

[stuck onyx]

anybody building IL2CPP on mac?

we've noticed its not possible to debug on device since Unity 2021

but nobody seems to care about this

[split folio]

Maybe not enough mac users for unity devs to be bothered?

[craggy spear]

That's not likely at all

#854851968446365696 on how to post code

[fringe timber]

Hello guys. Does anyone know how to resize a bone without affecting the child bones? The first approach I had seen was: (1) remove the children from the bone; (2) perform resizing; (3) relocate the children. With this approach, unity calculates the transforms automatically.

What I wanted to know is: what mathematical formulas are involved in this process of calculating transforms when a child is assigned to a new parent.

If anyone knows, it will help me a lot!

This was my attempt at implementation: https://gdl.space/azuhenizir.cs
I left the comments in the code because they were attempts that didn't work out, but they can be useful.

My problem in this implementation is considering the following scenario:
BoneA (resized via script)
-> BoneB (resized via script)
-> BoneC (unexpected resize)

If I resize BoneA and BoneB, BoneC will have a scale that doesn't match the original scale when BoneA and BoneB have not changed.

[sly grove]

I recommend changing your hierarchy like this:

BoneA (not resized)
   -> BoneB (not resized)
       -> BoneB visuals (resized by script)
       -> BoneC (not resized)```

[fringe timber]

it would be like separating the bones from the muscles of the character, right? The bones would literally just be the structure while these bone visuals would be what I called the muscles.

It's a very interesting idea. I would still like to work with the simpler framework, however your solution will certainly be my plan B.

[jolly token]

You can't in current hierarchy. Combination of parent scale and child rotation can make child transform skew which you cannot revert from child transform with Unity.

[fringe timber]

I know it can break some things. However, this scale calculation will be performed after the animation has been performed (in LateUpdate). I also don't intend to change the size of the bone, just its thickness. I would like to use this for character customization.

[jolly token]

I don't think you get what I said.. you cannot un-scale parent with child's scale if child has non axis-aligned rotation

[jolly token]

If your intention is changing bone “length” then you should change child’s position with offset instead of scaling parent

[fringe timber]

The idea would be to change the scales of the X and Y axis (considering the coordinate system of this image).

[fringe timber]

Ok, I understood what you meant, but I didn't understand in practice if Unity doesn't allow me to scale or if it would be a mathematical limitation of the thing.

But I think the following. Assuming the default scale being 1, we would have the following:
-> BoneA (scale = 2)
-> BoneB (scale = 0.5)
->BoneC(scale = 1)

If I double the size of BoneA, then BoneB should be halved.

Now, if I double the scale of BoneB, BoneC should be halved, right? The result, in theory, would be this:

-> BoneA (scale = 2)
-> BoneB (scale = 1)
->BoneC(scale = 0.25)

But I still don't understand what's wrong with my script.

[jolly token]

This top cube is scaled by the other cube parent in bottom

You cannot revert this scale regardless of whatever scale value you give to the top cube

[fringe timber]

Sorry for having to make you draw it for me, but now I understand the problem. Thank you for clarifying this problem for me. In that case, I'll have to go to plan B.

[honest hull]

is there ANY way to have bindless textures or something similar for compute shaders in unity?
the whole not having them is making me pull my hair out trying to find an alternative

[frail kestrel]

Please #854851968446365696 on how to post long pieces of code.

And also, it's because it doesn't know what NetworkMessage is: NetworkMessage message = new NetworkMessage(); so you are probably missing a class NetworkMessage or some package.

[sly grove]

recruiting goes on the forums as per #📖┃code-of-conduct

[keen cloud]

would you guys make methods like this static

probably does not need to be in the advanced section lol

like when would you choose to make a method static

[jolly token]

When your method does not do anything with instance variable

[keen cloud]

okay cool so this is just internal stuff

so static it is

if every method in this class is static is that when you should just make the class static

[sly grove]

that's the only time you can make the class static

[keen cloud]

hm

okay lol

[sly grove]

also - only if it has no instance variables

[keen cloud]

makes sense i was on the path of static is evil but now im going the other direction with some of my classes

that fall under this category

[jolly token]

Static state (variable) is consider evil in that statement
Static method is just function

[sly grove]

static classes are good if you have a bunch of reusable, stateless utility methods basically.

Think Mathf

[jolly token]

Mathf ironically struct

[sly grove]

lol

[brisk pasture]

static methods and classes are fine

[sly grove]

conceptually though

[jolly token]

Yeah lol

[brisk pasture]

but lots of static state is just asking for future troubles

[keen cloud]

i would like to remove static state but add like stateless static classes

that just do things

one thing

[jolly token]

You'll also have to use static class for extension methods

[undone coral]

i don't recall il2cpp managed debugger connections ever working

are you on an apple silicon mac?

[undone coral]

why do you need to change the size of the bone for character customization?

i would create a few different rigs. i wouldn't modify the bones' dimensions at runtime. you have to use external tools for animation retargeting if you want it to look good

[little minnow]

Guys does anyone know something about tilemaps? I want that if I break my tile block, that it can spawn back on the available places... does anyone have a suggestion?

[sly grove]

#💻┃code-beginner or #archived-code-general

and show what you've tried

[dapper cave]

When doing Instance(instanceInScene) at runtime it creates a copy of a gameobject, and it seems to include all references too. The odd thing is, if I do .GetChild(0) on one of its transform, I get zero children even though in the Hierarchy view I can see those children. Any idea why?

[thin mesa]

doesn't sound like an advanced issue. post in #archived-code-general and show relevant code

[dapper cave]

definitely advanced because it's never happened after years of using unity and can't post 3K lines of code

and... fixed

[vestal condor]

what makes an instantiation call more expensive than another?

[shy meadow]

Is there a way to exclude native plugins from dedicated server builds? I can use define constraints for managed plugins

[undone coral]

for what purpose? you can delete them in a post processing step

i wouldn't overthink this

i remember this is painful

[shy meadow]

Just for minimizing the build artifacts, but for some, there might be license implications. You're right though, deleting/keeping them is perfectly fine since the server doesn't have the managed libraries that do call into the native plugin

[shy meadow]

We have build scripts for our project, so this is what I did for reference:

    private static PluginImporter _fmodstudio = 
        AssetImporter.GetAtPath("<path-to-plugin>") as PluginImporter;

    private static PluginImporter _fmodstudioL = 
        AssetImporter.GetAtPath("<path-to-plugin>") as PluginImporter;

    private static bool ServerExcludeFMOD(string _)
    {
        return false;
    }

    [MenuItem("Tools/Build/Server")]
    public static void BuildServer()
    {
        _fmodstudio.SetIncludeInBuildDelegate(ServerExcludeFMOD);
        _fmodstudioL.SetIncludeInBuildDelegate(ServerExcludeFMOD);
        
        // more build logic...
    }

[undone coral]

yeah just delete it for sure

[undone coral]

that's very unusual

what's up with the icons

maybe you called .getchild on the wrong thing

[half oasis]

Maybe my previous question is too simple for the code-advanced channel 😅

[light vine]

I have a question in regards to null checks. I understand null propagation/null coalescing bypasses Unity's equality operator override on UnityEngine.Object. However this still implies that if the C# reference itself references null it should return true until it is assigned.

I assume this behaviour has to do with Unity's serialization?

[tawny bear]

So something isn't returning null and you're expecting it to return null?

[coral folio]

Nah, it's weirder then that. From what they're saying, rb is null is false, but rb == null is true. Which is wacky.

[light vine]

Yes? I am expecting the variable to be null

[coral folio]

I got nothing, personally, but it's fascinating.

[light vine]

This can make sense if the variable was assigned but the UnityEngine.Object was "destroyed"

But in this case the variable wasn't assigned in the first place

[thin mesa]

have you perhaps serialized the field or have your inspector in debug mode? pretty sure those will both use unity's fake null until it has been assigned (at least in editor, not sure about in build)

[light vine]

What is extra weird is that I get this when I enter playmode, but when I exit and re-enter playmode it is true true which is what I would expect

[coral folio]

See, in the :old-person-icon: C++ days, that would be uninitialized memory or something. But I presume C# doesn't do things that way, because... 🪄

[light vine]

It's not serialized. This is the first thing I was thinking of as well. Let me check the YAML data to be sure. I tried to recreate it but was unsuccessful. (Maybe Odin doing something under the hood)

[light vine]

Well the C# instance doesn't get removed but the C++ instance on Unity's side does. All the Unity components are just C# wrappers around a C++ implementation

[thin mesa]

it's just unity being weird with its fake null for UnityEngine.Objects

[light vine]

Ofc the C# instance gets removed once the GC collects it but ye

C# is essentially std::shared_ptr<> galore

[thin mesa]

probably Odin, or if you have the inspector in debug mode unity will serialize everything it can in order to show the current values (seen this happen before with a serializeable class that wasn't a monobehaviour that wasn't marked as serialized)

#💻┃code-beginner message

[light vine]

Yup it was serialization after all

The attribute did the trick

But I can't replicate this on another Unity project so this has got to be Odin

Seems like I might have a fun thing to report for the guys at Sirenix

[thin mesa]

try the other project with the inspector set to debug mode and it will probably have similar results. i also wouldn't be surprised if odin did that intentionally for the same reason the debug mode inspector does it

[light vine]

"does it intentionally" you mean secretly assigning a UnityEngine.Object as a result of the serialization process?

[thin mesa]

seems like it's just the normal fake null you should be expecting with objects deriving from UnityEngine.Object and not actually a real instance

[light vine]

Interestingly enough it's the opposite

So for example I have the same setup with Animator and other components but only the RigidBody2D was a problem

Oh wait right I forgot to remove NonSerialized

nvm

[light vine]

But this still comes back to my previous statement ^

If in the serialized data the UnityEngine.Object isn't assigned why not assign null when deserialized?

[thin mesa]

this is part of why you should never use null operators and only use == to check for null with anything deriving from UnityEngine.Object

[light vine]

I understand that. I still wanna understand what is going on x)

Cus clearly my understanding of why I should avoid bypassing unity's equality operator override is not complete

Especially considering I can turn a 185 LOC file into a ~35 LOC file

[stuck onyx]

they worked fine on Unity 2020

then we changed to unity 2021 and no more debugging, breakpoints fail and app freezes

[tawny bear]

Did you update all the stuff associated to a new version of Unity?

Packages etc

[stuck onyx]

im now on a silicon mac but in march i tried unity2021 on an intel and it was the same

its an issue in the rider's issueboard

but no one cares

[stuck onyx]

packages like?

but worst thing is i installed VS and debug breaks too

[tawny bear]

I don't know just the common things you'd do alongside with upgrading to a new version of Unity, really

[stuck onyx]

so, we already doubt its rider's fault

[tawny bear]

Other than that I don't know anything about this topic

[stuck onyx]

we have updated all the necesary packages yes

[tawny bear]

Is it breaking for several devices?

[stuck onyx]

its not a problem of packages thats for sure, something's different on unity 2021 on standalone debug and breaks visual studio and rider

that im not sure i just have 1 testing device, but i've contacted other people in rider's forum and same is happening for them

the factors seem to be MAC, I2LCPP and unity 2021

mac im not 100% sure

this problem has been dragging since last april

considering rider is a paid software is quite embarassing

but considering debugging breaks on VS too....

[tawny bear]

Are you able to test it on another OS?

[tawny bear]

I didn't know rider was paid actually, good to know

[stuck onyx]

It's paid but to be honest , except for this debugging shit, is worth it

[tawny bear]

Fair enough

[stuck onyx]

no, all my devices are mac but im sure if it would happen on windows there would be more people complaining

[tawny bear]

I'm a cheapskate though so I'm sticking with VS heh

[tawny bear]

Fair point, have you tried running the same problem in a new project?

[stuck onyx]

uhmmm no, but that seems a good idea

ill try that

[tawny bear]

Yeah I'd try that, see if it's just a "faulty" project

[stuck onyx]

I'm also a cheapstake but if you work with unity, once you try Rider, you cant go back

plus im on mac, VS sucks on mac

😄

[tawny bear]

That's probably true

[tawny bear]

Oh that's rough

What's so bad about it on mac?

[stuck onyx]

well this last version i installed seemed better than the last one

but the first one i tried... (4 years ago maybe?)

it was like a lite version, i dont know how to explain

maybe i installed a wrong version, i was noob with mac back then

but it was extremely uncomfortable to work with

like.... an improved mono

was it called mono? that ide?

yeah something like that

anyway thanks for the idea ill try it

[tawny bear]

Oh yeah that's long ago, VS has made a lot of improvement since then

VS 2022 is especially nice

(VS 2019 is the standard that "comes" with Unity)

[stuck onyx]

probably the 2019 is the one i tried

back in the days

[tawny bear]

Yeah 2022 has new funky features

Such as a better intellisense which is very nice

I'm never gonna go back to VS 2019 that's for sure lmao

[stuck onyx]

I encorage you to try Rider, even if its a cracked version,

[tawny bear]

I don't wanna type out a whole GetComponent, I just wanna press tab and be done with it lmao

[stuck onyx]

yeah for sure thats one of the most basics things Rider can do

[tawny bear]

I might at some point, I currently kinda have different priorities

Currently trying to decipher a game I wrote 2 years ago

Which isn't even in C# Unity, but in Java Processing

So that's fun

And there are like 0 comments

[stuck onyx]

lol

whats the point on doing that?

nostalgia?

wghats the game about ?

[tawny bear]

I mean if it's paid it'd be pretty bad if some kind of intellisense isn't a feature

[tawny bear]

I'll be "converting" it to Unity

But I can't exactly copy the code 1:1 y'know kek

[tawny bear]

It's a relatively small game, it's about choosing what is a good password is and what a bad password is

You've these passwords that fall from the sky and you've to drag them in the red/green box respectively to if they're bad/good

[stuck onyx]

it doesnt sound really exciting

😄

[tawny bear]

It's just a small little game you'd plop on a website to make cybersecurity more fun

It's not exactly a game you'd play for hours lol

You'd be done with in like 5 minutes really

[umbral trail]

I am creating a game object with a mesh collder/rigid body, but sometimes the collider is offset from the visual mesh (they use the same mesh), is there any known issues with this? What would be the correct way to fix it?

[sly grove]

This is not a code problem

[umbral trail]

it is all done at runtime, including generating the mesh

[worldly imp]

Is the collider or the mesh renderer a child of the GameObject?

[umbral trail]

nope, all in one

[worldly imp]

Odd

[umbral trail]

(if it helps, the mesh and initial object is generated by turbo slicer)

if I change the position in the editor, the mesh collider snaps back to the correct position

so I'm wondering if there's some internal state in the rigid body or the mesh collider

[tawny bear]

Ah that might explain it

[undone coral]

yeah i mean you found a real bug

if i paid $5,000/year for unity support i'd ticket it for you lol

[stuck onyx]

a bug nobody cares for 1 year almost 🤣

[undone coral]

but i don't

i should

[stuck onyx]

ill try to get in contact with them with my shitty subscription

[undone coral]

they're going to tell you to file a ticket with QA

which means it will take 9mos

and between the time you file and the time they look at it, which is like 9 months, they (QA) asks you to reproduce with the latest version of unity. @crude granite the bad QA filing experience remains the #1 obstacle for me and probably many others from paying for unity support

it would be nice if they would prioritize issues filed by sophisticated people

instead of issues by payer

[hexed meteor]

Anyone have any tips for starting out with building something like ProBuilder ?

Yeah I just think it's absolutely terrible

Unity 2022 IL2CPP + System.Text.Json Build Error

[coral citrus]

Hey, would it be possible to pick someone's brain about an issue with a custom render texture?

I'm sure the functionality I'm looking for exists, I'm just not sure where to find it. Basically, I'm running a shader on one update zone (to recolor, say, a sword on a texture), then I clear that zone, make a new zone, and update the render texture again on the new zone with the same shader.

This works fine, but it clears the results from the first zone's update. Is it possible to have the updates "persist"/accumulate?

[undone coral]

you can blit to specific regions

the blit shader has these parameters

you can render to a render texture representing the whole zone, then blit it to a region of another render texture that you use to texture your model

you can explore RTHandles and how the SRPs do this pretty routinely

does this help?

so you shouldn't be recycling a single scratch render texture for all of your stuff

i'm not 100% sure what you mean by zones though

[coral citrus]

i need to look up blit since i haven't seen that used yet but one second, let me see if i can illustrate it

this is the "starting" texture- it's all updated to be white, but that's irrelevant

this is after i create an update zone on the crt for just this torso sprite- it functions as you'd expect, works great, but if i then update the crt a second time, it'll wipe away that since it's not in an update zone, presumably? or because it's pulling from the base texture again

[coral citrus]

this seems very helpful though, i haven't seen this at all so i need to research it to see if it works

for me anyway

[undone coral]

okay

why.... are you doing this

what is the idea?

based on that image, you know, you can tint sprites

right there in the sprite renderer / ui image

so what are you really trying to do?

using customrendertexture is very built in render pipeline

[coral citrus]

it's a long story and very complicated but

the gist is that i'm using something called spine2d, which is just a skeleton animation software for 2d stuff, whatever

my issue is that i'm trying to handle a dye system and every slot (aka each of the individual sprites above) needs to be recolorable to any hex

the shader does that fine enough, since each sprite needs to have some degree of color detail (it recolors based on the rgb values of each sprite, the default is just white/grey)

the problem arises when you try to apply shaders to each piece of the skeleton, which is what i'm doing in the existing version of the game

it causes horrible lag as you'd probably expect from having 10-20 people on screen at the same time, and applying just one shader over the entire skeleton wouldn't really work either

so the solution i've arrived at is creating a copy of the texture per skeleton and recoloring pieces of it once, trading horrible rendering lag for a one time cost + some mild memory usage

[abstract basalt]

can't you use the same texture and duplicate the material, and then just change a tint parameter on the material?

Is this a custom shader?

[coral citrus]

it is yeah, and because the full texture contains all slot images but different slot images will take different material parameters (e.g. if you want a red sword and a brown shirt)

i've tried using multiple materials + a render separator component in spine2d but it has separate issues + it's a lot less performant

[keen cloud]

In what cases should you use interfaces? Like why would you want an empty method

[humble leaf]

To force whatever implements the interface to use it

[keen cloud]

Yeah I’ve looked at examples and I see what it does but I mean what’s the context where it’s best used?

Like where would I use it in my code (generally)

[sly grove]

When you want to have code that can process anything that has a certain method, without caring what those things actually are

For example if you want to write code that raycasts into the world and "interacts" with things, you might want an Interactable interface

so it doesn't matter which thing you hit you can just do GetComponent<Interactable>().Interact();

and not care what the interaction actually does

maybe it flicks a light on/off, maybe it activates a rocket ship, whatever, the raycast code doesn't need to know or care.

[keen cloud]

Hm okay would you happen to have a non mono behaviour example as well? I’ve seen them online again but I’m just trying to place where I’d use them in my own code to make things easier

Like “to make things easier”

[iron fulcrum]

If I have a reference to a scriptable object, is there a way to get its path inside assets?

[sly grove]

imagine the same thing, just not a MonoBehaviour 🤣 . The monobehaviour part wasn't important to the example

[sly grove]

in the editor, or in a build?

[keen cloud]

My mind works way too linearly but I’ll try my best lol

[sly grove]

Ever hear of IEnumerable?

[keen cloud]

Yes I’m trying to think of that as well but I’ve only used it with co routines

[sly grove]

that's IEnumerator

which is related

[iron fulcrum]

in a build/code

[sly grove]

Any class that implements IEnumerable can be iterated over with foreach. foreach does this under the hood:

void ForEach(IEnumerable subject, Action<object> action) {
  IEnumerator enumerator = subject.GetEnumerator();
  while (enumerator.MoveNext()) {
    action(enumerator.Current);
  }
}```

this is basically how foreach loops work

it works on anything that implements IEnumerable

that's why you can foreach on Arrays, Lists, HashSets, Dictionaries, etc...

and it's thanks to the magic of interfaces.

we know we can call GetEnumerator() on anything that implements the interface because that function is in the interface

[keen cloud]

So literally it’s supposed to be for very broad circumstances

[sly grove]

sorta

[keen cloud]

Hm

[sly grove]

it's for when you want to be able to process disparate objects in a unified way

[keen cloud]

So yeah that’s kinda where my understanding was at but I think I get it more now lol I gotta find places to use it in my code somehow

[stoic oar]

does anyone know how to represent IEEE754 in binary and decimal with c#

BitConverter.ToSingle()
GetBytes()

i don't understand this function

[sly grove]

BitConverter.GetBytes is the way for sure

"represent IEEE754 in binary" is kinda vague though, that's literally what a float is

I guess you want to see the 1s and 0s for yourself right?

https://stackoverflow.com/a/4829390 to convert each byte in the array to a string

[stoic oar]

you have a exemple for get this ?

[sly grove]

Just explained

[stoic oar]

I don't understand how to use this function

[sly grove]

GetBytes to get a byte array.
Then loop through each byte using the link to convert to strings

And just concatenate them all together

Seeing as you're asking in #archived-code-advanced I'll assume you can do this on your own.

[stoic oar]

no i am a beginner😅

[sly grove]

You're in the wrong channel

[stoic oar]

yes thanks

[stoic oar]

i'm locked in this

[thorn cradle]

Hello,
I do not know if it belong in that channel but I would need help with a crash report.
Would somebody have an idea what could be wrong here? Is it something I can do against it?

We are using Ecs. 0.51 with Unity 2021.3.16

[ruby gull]

is it possible you have any disabled objects or invisible colliders in those spaces?

Is your terrain generating any grass?

try moving your terrain elsewhere and rebaking, see if the spots follow the terrain or stay at that position in the world

[knotty sage]

Hi, I asked about this yesterday in the URP channel but didn't get any bites, maybe this channel's a better place for it -

I'm trying to render a prefab to a texture for use as a thumbnail. I'd rather not add it to the scene to render and I can't see a way of creating, rendering and destroying an isolated secondary scene, so I'm using the Graphics object, a CommandBuffer and a RenderTexture to do this, looping through meshes and sub meshes and calling 'CommandBuffer.DrawMesh' on each sub mesh and material, while setting up the view and perspective matrices manually.

So far so good, it renders the mesh to the texture. However, it's only rendering the diffuse channel - emissive is ignored and there's no lighting. I've tried enabling various keywords and uploading shader uniforms related with lights but these have had no effect - I suspect there's some #def for lighting that I'm missing. I'm also not sure if this is forward rendering, deferred or whatever or how to affect which pipeline is used. I can't find any documentation on this, so a pointer in the right direction would be very appreciated.

If it is the deferred pipeline, maybe that's the problem - I'm seeing the diffuse buffer and I need to set up all the other buffers properly and then resolve the lighting in another pass? Or get it to do forward only perhaps.

[river sand]

hey every one i have a script for handling my head bob in my fps system , now i want to know is there any way to have events exactly on the frame when the camera starts and ends the arc movement?

        private void Awake()
        {
            StartPos = transform.localPosition;
            StartRot = transform.localRotation.eulerAngles;
        }

        private void Update()
        {
            if (!Enabled) return;
            
            CheckMotion();
            ResetPos();
            
            if (EnabledRoationMovement)
                transform.localRotation = Quaternion.Lerp(transform.localRotation, Quaternion.Euler(FinalRot), RoationMovementSmooth * Time.deltaTime);
        }
        private void CheckMotion() {
            
            float speed = new Vector3(player.targetVelocity.x, 0, player.targetVelocity.z).magnitude;
            if (speed > 0.1f)
            
                HeadBobMotion();
        }
        private Vector3 HeadBobMotion()
            pos = Vector3.zero;
            pos.y += Mathf.Lerp(pos.y, Mathf.Sin(Time.time * Frequency) * Amount * 1.4f, Smooth * Time.deltaTime);
            pos.x += Mathf.Lerp(pos.x, Mathf.Cos(Time.time * Frequency / 2f) * Amount * 1.6f, Smooth * Time.deltaTime);
            transform.localPosition += pos;
            FinalRot += new Vector3(-pos.x, -pos.y, pos.x) * RoationMovementAmount;
            return pos;
        }

        private void ResetPos() {
            
            if (transform.localPosition == StartPos) return;
            transform.localPosition = Vector3.Lerp(transform.localPosition, StartPos, 1 * Time.deltaTime);
            FinalRot = Vector3.Lerp(FinalRot, StartRot, 1 * Time.deltaTime);
        }
    } ```

[ruby gull]

I'm sorry to sway off from your question, but what's the issue with adding it to the scene to render it? And if you're generating thumbnails for prefabs, wouldn't this be better done in the editor instead of generating at runtime?

[stoic oar]

using System;
                    
public class Program
{
    public static void Main()
    {
        float f = 19.5f;
        var bytes = GetBigEndian(f);
        Console.WriteLine("{0} => {1}", f, BitConverter.ToSingle(bytes,0));
        Console.WriteLine("{0} => {1}", f, GetFloatFromBigEndian(bytes));
    }

    static byte[] GetBigEndian(float v)
    {
        byte[] bytes = BitConverter.GetBytes(v);
        if (BitConverter.IsLittleEndian)
            Array.Reverse(bytes);
        return bytes;
    }

    static float GetFloatFromBigEndian(byte[] bytes)
    {
        if (BitConverter.IsLittleEndian)
            Array.Reverse(bytes); // We have to reverse
        return BitConverter.ToSingle(bytes, 0);
    }
}

[knotty sage]

This has to be at runtime, this is an app that generates thumbnails at runtime.

[stoic oar]

i try to get it but i don't understand

[ruby gull]

Why not add it to your scene and render it on it's own layer?

[knotty sage]

I m sorry to sway off from your question

[sand inlet]

anyone knows the command line arg to build a dedicated linux Server?

[sage radish]

If there is a built-in argument like that, it's probably worse than writing a static method that uses the build scripting API and executing it with the -executeMethod <ClassName.MethodName> argument.

[sand inlet]

So basically write a Build Script and then
"EditorPath" -quit -batchmode -nographics -projectPath "ProjectPathName" -executeMethod <ClassName.MethodName>
?

[sage radish]

Yeah

[sand inlet]

Thx @sage radish

[misty walrus]

Hi, I am trying to implement addressables with remote packages. I have a problem about caching. I want some assets to be locally cached with their latest version. The only method I can think right now is check GetDownloadSizeAsync and if it's bigger than 0, load it. I have a problem and a question about this.
Problem: I really don't need to Load the asset but to rather simply cache it locally, is that not possible?
Question: Since addressable handles unloads itself, if I have to Load the assets and never save a reference to them, will Unity unload the bundle after the method call ends automatically?

[finite burrow]

Is there a way to combine a UploadHandlerFile with the multipart form data?

var webRequest = UnityWebRequest.Post(requestData.url, new List<IMultipartFormSection>() {
            // new MultipartFormFileSection("vanillaZip",await File.ReadAllBytesAsync(tempPath) , "0.0" + ".zip", "application/zip"),
            new MultipartFormDataSection("version", "0.1"),
            new MultipartFormDataSection("bundleHash", "asfasfas")
        });
        webRequest.uploadHandler = new UploadHandlerFile(tempPath);
        webRequest.uploadHandler.contentType = "application/zip";

e.g moving from the FormFileSection to the UploadHandler. The file in this case is large (1-5GB) and the file section won't chunk or stream, requires the entire thing in memory

[wooden night]

also this channel isn’t used a whole lot so it may take a while if there’s a conversation going on and it’s been going for a while and it’s been a while since I last asked i usually send a message to draw attention to my question something like hey could someone help with my issue

[worldly imp]

Oh shit KaiDevvy moment

[ruby gull]

👋

[onyx blade]

I have a function that is calculating the bounds of an object first, and also calculates the distance from its pivot to the left limit and right limit in 2 variables. But the calculation I am doing seems wrong...
I drew some gizmos to see the results. I know the bounds is correct cuz I double checked with manual measurements

   public static Bounds CalculateBounds(this GameObject target)
   {
       var bounds = new Bounds (target.transform.position, Vector3.zero);
       Renderer[] renderers = target.GetComponentsInChildren<Renderer>();
       foreach (Renderer renderer in renderers.Where(x => x.gameObject.activeInHierarchy))
       {
           bounds.Encapsulate(renderer.bounds);
       }
       
       ARManager.Instance.instanceController.sceneRoot.transform.SetPositionAndRotation(parentPosition, parentRotation);
       
       if (target.TryGetComponent<DatabaseReference>(out var reference))
       {
           reference.Bounds = bounds;
           reference.Reference.distanceFromCenterRight = Math.Abs(bounds.max.x - target.transform.position.x);
           reference.Reference.distanceFromCenterLeft =
               Math.Abs(bounds.size.x - reference.Reference.distanceFromCenterRight);
       }

       return bounds;
   }

   void OnDrawGizmosSelected()
   {
       Gizmos.color = Color.red;

       var positionLeft = new Vector3(transform.position.x - reference.distanceFromCenterLeft, transform.position.y,
           transform.position.z);
       var positionRight = new Vector3(transform.position.x + reference.distanceFromCenterRight, transform.position.y,
           transform.position.z);
       Gizmos.DrawSphere(positionLeft, 0.1f);
       Gizmos.DrawSphere(positionRight, 0.1f);
   }

[wooden night]

Holy shit that’s a lot of code for something so simple

isn’t there the bounds method? i think it’s under the mesh renderer

[onyx blade]

there is a bounds method, but that only does it for one renderer, not for compounded meshes

I honestly wish I didn't have to do that

[wooden night]

idk what those are but damn

yea i would too

[onyx blade]

compounded = multiple meshes in one parent. f.e. the black pillar and the glass panel are separate under the same parent, but I need to have the bounding box of them as one object

[wooden night]

you seem to know what you’re doing a lot more then i do, so could i ask you a problem i was having?

[onyx blade]

lol, go ahead

[wooden night]

oh so having a couple children who also have meshes

[wooden night]

i was making a loading bar right, and i have the width of the loading bar set to LoadingBarObjX but for some reason it reads the width as a negative and i’m trying to make a if statement that checks if the width is bigger then 0 and so i have to check if it’s less then 0

[onyx blade]

yeah, getting their bounds and using encapsulate allows you to get the bounding box of things together. You can use that to get bounding boxes of an entire scene too for example.
(Its very useful to generate a collider for objects that can change at runtime and need adjustments to the colliders

[wooden night]

Interesting

[onyx blade]

which UI system are you using?

[wooden night]

idk just unitys hi

ui

[onyx blade]

ah the gameobject based one?

[wooden night]

yea

i think

the one where you right click go to ui and choose what you want

[onyx blade]

yeah, you arent working in separate documents that look like html

uhm lemme think

[wooden night]

what?

[onyx blade]

dont worry about it

[wooden night]

ok

[onyx blade]

are you using an image?

if so, set the image type to filled with fillmode horizontal and origin left/right if needed. then you can set the fill amount to a value between 0 and 1

https://answers.unity.com/storage/temp/160017-ex2.png

alternatively @wooden night good old brackeys https://www.youtube.com/watch?v=BLfNP4Sc_iA

[wooden night]

yes

alright i’ll try that

It’ll be a couple hours though i’m in school rn

[onyx blade]

thats alright, feel free to tag me later if you need help if it doesnt work

[proper sparrow]

I'm making a VR game in unity where you sit on a magic carpet, and I want to be able to grab the corners of my rug, which already are using the cloth component

I have tried to attach grabbable cubes on the corner of the rug, but they won't stay

and follow the rugs movement

[wooden night]

Ok appreciate it

[onyx blade]

when you say dont follow the rug movement, do you mean actual movement of the rug or an animation of the mesh?

[proper sparrow]

Animation of the mesh

[onyx blade]

that makes sense, since the animation of the mesh will not change the meshes position at all

well, unless you have root motion but thats not relevant here

[proper sparrow]

Is it possible to attatch a cube to the cloth animation?

[onyx blade]

I think you can, but the only way I can think you can do that is by getting the vertices of the corners you wanna grab and manually setting the position of the cubes to that vertex's position

[proper sparrow]

But how?

[onyx blade]

you would need to read the meshdata and find the 4 corners

[proper sparrow]

Is that a class?

Or how do i acess the meshdata?

[onyx blade]

https://docs.unity3d.com/ScriptReference/Mesh-vertices.html

[proper sparrow]

Thank u Torben, I'll give it a try

[undone coral]

is this for a mobile platform?

[finite burrow]

no

[undone coral]

hmm

maybe use httpclient then

you can also try besthttp/2

are you trying to upload something to an s3 bucket?

[versed coyote]

Hm I a using Zenject Signals at the moment.
Just by accident I stumbled over this method here:

https://docs.unity3d.com/ScriptReference/Component.SendMessage.html

I wonder which is performing better? The way I am using Zenject Signals is actually easy to swap with Component.SendMessage. However I'd love to know about any pitfalls with that approach

[undone coral]

what does the fact that nobody uses SendMessage tell you about Zenject?

[pine anvil]

How to make the NavMeshAgent not be repelled by the player or player object? (pls ping me)

[versed coyote]

Tells me nothing about Zenject. But it tells me that SendMessage is no better alternative

[undone coral]

don't use zenject

it provides no value, it is negative ROI

[versed coyote]

Coming from web engineering and using Spring Boot for most of my backend software I am very keen using Dependency Injection. And Zenject really helped me tidy things up and keep out of the Unity Editor for most of the time

[versed coyote]

What is the actual problem with Zenject's Depdency Injection?

[undone coral]

what are your goals? to make a game?

[undone coral]

i use vertx.

[versed coyote]

Well I am using it for my current project. This is the Unity Server isn't it 😄 - so yes a game

[undone coral]

okay well i think you'll figure it all out

i wouldn't use spring boot either

[versed coyote]

On my first glance I could not see any Unity integration. Zenject allows a nice approach to inject Prefabs and such quite nicely

[undone coral]

i'm saying, when i write a backend application in Java, i use vertx

[versed coyote]

Well it's a matter of taste or use case - what's your issue with Spring Boot? I am not dogmatic just wanna know about different perspectives

[undone coral]

in every setting where i've interacted with senior or sophisticated programmers, dependency injection, like annotations, are code smells

if i saw zenject used in a unity game, my reaction is "this person is dunning kreugering their way into never delivering a game"

keep out of the Unity Editor
use pygame

[versed coyote]

Hm. Well no offense but you did not yet provide any real arguments. You just say that things (DI in this case) is bad. But aren't really explaining why you think that is?

[undone coral]

the substantive argument is "experience" which isn't something you can just write

i'm not a content creator, i don't have a youtube video with 5 bullet points about why zenject is bad

i can only give you my opinion

it's just opinions

you should look at vertx for java

[versed coyote]

Well I really want a taste of that experience - that's why I am so persistent here. I have my 8 years of very good experience with DI. And just wanna understand the other side of that view

[undone coral]

in my experience, the vast majority of dependency injected dependencies only have one implementation, so having the dependency injection framework and all of its attendant flaws and bureaucracy are redundant

there aren't "multiple competing vendors" in a unity game. if you "change vendors" you made a mistake

you won't gain value from having the DI framework. it will just add more work to something that was going to happen anyway.

this is true in spring boot too

[versed coyote]

Well Zenject in my Unity project actually removed the need of using [SerializedField] and putting systems and script into different gameobjects by hand really much.

[undone coral]

i think the appeal of zenject and DI is that it's a way for people to think and organize code

[versed coyote]

Yeah for me it removed the "manual" labor. I want to write the game and not drag and drop it

[undone coral]

by hand
one thing i learned very early on in my career is that by hand is a lot faster and better sometimes

for example, in animation, sometimes you just rotoscope by hand, and it will be faster for even a thousand frames, than dealing with a piece of dedicated software

[versed coyote]

yeah but it's impossible to navigate through those connected components and objects

[undone coral]

you're actually moving away from the most promising traditions of video game development

[versed coyote]

While having everything in my codebase it's very easy to navigate thanks to modern IDEs

[undone coral]

is your game Factorio?

this is why i asked you what your goals were

because it doesn't sound like the goal is to make a game

do you see what i mean?

[versed coyote]

I don't mind. I am not doing it for the tradition but for the sake of the project and maintanability

[undone coral]

or at least, what is the specific kind of game you want to make? then i can at least say if your opinions are aligned with that kind of game

for example, in medicine, people who find blood and guts icky, there are a few specialities that are really compatible with that. radiology comes to mind.

[versed coyote]

It's not factorio - but it's a quite ambitious project and not an arcade small game. Therefore I need to have a solid architecture from scratch

[versed coyote]

It's an MMORPG

[undone coral]

well what is maybe a small step towards that goal that you are excited about?

[versed coyote]

is that a question?

[undone coral]

yes*

like what would be small step towards achieving that vision

that most excites you

like many people go into medicine "to help people" which is good, that's kind of the answer "make an MMO"

[versed coyote]

I can't follow you to be fair? You ask for my motivation?

Ah ok

[undone coral]

and a small step to that is "become an X"

and if you hate blood and guts it makes sense if that is "become a radiologist"

[versed coyote]

Well I am a huge Fan of Wurm Online. I'd like to have a small, loyal playerbase to enjoy the game world I craft. Just like WO does

[undone coral]

this is important for at echnology choice

okay... well wurm online

i just visited it

so like a first step that would make sense to me

is "you can build a building inside your unity game"

[versed coyote]

Well don't get me wrong. The project is already in development

[undone coral]

i just feel like that involves a lot of UX... you're going to be touching the editor

[versed coyote]

At the moment the netcode for multiplayer movement is implemented

That's my first step here

[undone coral]

hmm

i would say maybe focus on like, a simulator for animal behavior

something where the result is, essentially, a graph

something more Dwarf Fortress

[versed coyote]

Well maybe we just drop out of context here - I already have a full game design in place

[undone coral]

i just want you to thrive

[versed coyote]

If you're interested I can share you a discord link via DM

[undone coral]

sure that sounds nice

[versed coyote]

That's a nice thing to hear!

[undone coral]

okay i gotta go

you'll figure it out

[undone coral]

Anyway i think the best perspective here is that Unity is a bad choice for MMOs. You can use unreal instead if you need a multiplayer game

Unity is a bad choice for many kinds of real-time multiplayer games

Unity net code is bad, and the vendor multiplayer frameworks are bad, and that’s why hardly any real-time multiplayer games succeed in Unity

If you’re excited about real-time multiplayer don’t use Unity

I wish they were more honest about this

@undone coral DOCTORpangloss giving health care analogies. well played :D

[wooden night]

omg it took so long to find this, alright so under raycast padding there is no image type

[sly grove]

It only shows up if you put a sprite into Source Image

[wooden night]

uh

what

Oh

I see

[sly grove]

^

[wooden night]

It looks weird when I put it on filled though

Is there anyway to fix my issue without setting a sprite?

[sly grove]

just set a blank white sprite

also what's your issue anyway

[wooden night]

I have a loading bar right and the loadingbarobj I have LoadingBarObjX and y set to its size however it reads is size as a negative

but it doesn't say it does

[wooden night]

Yea but when I put it on filled it looks weird

[sly grove]

weitd how

[sly grove]

with a filled image you never need to mess with the size

[wooden night]

That used to be a rectangle

[sly grove]

you put a weird sprite in

use a blank white sprite

[wooden night]

I kind of need to

[sly grove]

why

[wooden night]

Its a loading bar

[sly grove]

what are you trying to make

a loading bar?

[wooden night]

Yea

[sly grove]

That's a standard filled image

no need to change size

[wooden night]

Do you know how loading bars work

[sly grove]

https://www.youtube.com/watch?v=J1ng1zA3-Pk

yes

very well

I've made many

Filled image is far superior to messing with UI size in code

[wooden night]

Ok, then you know they move or change in size

But that doesn't change the fact it looks weird

[sly grove]

use a blank white square sprite

it won't look weird anymore

[jolly token]

This is not code question nor advanced 🤔

[wooden night]

It is a code question

Not advanced but

[wooden night]

this is what it looks like by default

[sly grove]

The video I sent explains how to get that shape and use fill

[wooden night]

its 12 mins

When does he talk about that?

[sly grove]

You've been bugging me for longer than 12 minutes

[wooden night]

You dont have to continue talking to me

I appreciate the help

Oh shit, huh some some sprites do the weird thing and some dont

Its just the sprite, I thought I had to do something

[burnt egret]

proud of this particular bit of code i wrote

IEnumerator GetLocalizedText(string key, TMPro.TextMeshProUGUI text)
    {
        var value = dataModel.keyValue.Where(x =>
        {
            //remove white spaces if theye are there
            if (x.name.Contains(' '))
            {
                //may be issue with upper/lowercase
                string temp = "";
                x.name.CopyTo(0, temp.ToCharArray(), 0, x.name.Length);
                ReplaceWhitespace(temp, "");
                return temp.Contains(key);
            }
            return x.name == key;
        }).ToArray()[0].value ?? string.Empty;
        Debug.Assert(value != string.Empty,$"{key} returned no value for GetLocalizedText in IntermediateView!");
        var asyncOperationHandle = LocalizationSettings.StringDatabase.GetLocalizedStringAsync("WaitingRoom", key);
        while (!asyncOperationHandle.IsDone)
            yield return asyncOperationHandle;
        text.text = $"{asyncOperationHandle.Result}: {value}";
    }```

it would look a lot nicer if i didnt have to get rid of whitespace but hey its neato

and it works so thats pretty cool too

[fresh salmon]

//may be issue with upper/lowercase
If you want case-insensitive comparison, Contains can take a second argument that dictates the comparison type. Pass any of the IgnoreCase options

[burnt egret]

oh neat! thank you

[fresh salmon]

I also don't quite get that array copy operation, if you just need to replace whitespace you can do .Replace(" ", ""), it won't modify the original string, but rather return a new one

[burnt egret]

oh really? i thought for some reason that since strings arent a value type it would edit the original string

woopsie

you just saved me a bunch of performance thank you ❤️

i should also probably make the other case call Contains as well

[fresh salmon]

They aren't a value type you're right, but C# treats them specially, they're immutable. Changing one always creates a new one in memory that contains the new value

[burnt egret]

interesting, thats super cool i didnt know that

is there a nicer way to do Where where i dont have to convert it to an array and get the first value?

[fresh salmon]

Sure!

var val = dm.kv.Where(x => x.name.Replace(" ", "").Contains(key, StringComparison.OrdinalIgnoreCase));

One liner to rule them all

[burnt egret]

will that return the string im looking for or some weird datastructure?

[fresh salmon]

That returns a collection of string

[burnt egret]

ah okay, yeah i want just the first value of the collection and i was wondering if i could get that without having it create an array

[fresh salmon]

I just saw that you take the first one in that code, so you can replace the Where with a First to get the first matching string directly

[burnt egret]

cause i know there will only be one value

oh neaaat okay

what im getting from this is that i should go read Linq's documentation lol, thank you so much

[fresh salmon]

Note that with First you will get an exception if no match was found. Use FirstOrDefault, which doesn't throw, but returns null if nothing is found

Linq comes with time, you learn something new about it every day. A few days ago I discovered the MinBy and MaxBy methods which are different from Min and Max

Oh yeah and if you always expect to have only one match in that list, ever, then you can use Single instead of First, which throws if no result, or more than one matches are found. If it blows up in your face, you have duplicates somewhere!

[burnt egret]

omg, thats awesome

alrighty definitely doing that now

thank you so much!

since i never took a course on C# in university, i cant help but feel like i dont quite have a holistic grasp on the language, i actually joined this server with the intention of fixing that + i feel the same with Unity

[brisk pasture]

assuming you did Java in University, if so you already have a good handle on how C# works. just different names on things

[misty glade]

Is there any way to view/inspect the optimization I'm getting out of Sprite Packer V1/V2?

I'm getting some pushback from my artist who insists on generating sprite sheets versus individual textures, since I was under the impression Unity handles a lot of this packing automatically.

How can I research this? Or find out if it matters/doesn't matter for a bunch of textures we're about to use in our project?

[burnt egret]

i did C++

[violet comet]

Maybe use the frame debugger to see draw calls? But afaik a sprite atlas Is basically just a huge texture

So whether your artist puts them all into one sheet or multiple or 100, and you pack them all into 1 atlas, it'll be 1 texture and 1 draw call

[misty glade]

Any changes to the file size of the distribution? He's sorta insisting on this extra effort (him packing them into sprite sheets and me unpacking them) and.. I'm positing that it's not really worth the effort right now. A point in his favor, they are relatively large images and there's a lot of them, so optimizations would be nice. They're backgrounds for cutscenes.

850x480

(and there's probably going to be 20-30 of them)

[heady linden]

Hey,
So the AI Destination is looking for a transform to follow,
https://gyazo.com/694763d14cf26e2f53ea7c5219d80ae4
(player transform)

But i want it to follow the player when its walking into a detection collider,
So i made this script: https://pastebin.com/9TMK0uR3 (which is working and all that)

But, now i need my AI destination to read out a transform from a list, ONLY when its availible,
List: https://gyazo.com/797602d8c82660e3124b6818dc93cec2

Player transform will be added into that list when its walking into the detection collider,
How i can let the destination script read out if something is in that list? and then get THAT as transform to follow when its in the list?
Cus i looked up a lot of stuff, and im kinda lost XD

[sterile snow]

Hmm does it make sense to be using custom attributes to define such things like identification strings with classes? Essentially metadata that never changes and needs to be directly associated with a class, whether an instance of it is created or not.

I was pondering just doing that with a static constant though.

[heady linden]

Do i maybe have to add a canWalk bool? And let the enemies define paths always. But only walk them when canWalk (so enemy in range)? Or will that create lagg if i have a lot of enemies? (Dots pathfinding btw)

[jolly token]

If you are using sprite atlas then you are basically doing same thing 🤔

[misty glade]

Point is, I don't want to - I'm just pointing to the textures directly and letting unity handle compression/optimization. I didn't want to fuss around with it but the artist is kinda digging in and saying that we should

[jolly token]

Sprite atlas is for batching benefit, rather than file size

[misty glade]

oh so it doubly doesn't even matter

[jolly token]

Sprite atlas handles that, you just directly use sprite and it packs into a single texture

[misty glade]

yeah, tbh I kinda cbf with this right now.. i have a zillion fires and product launch is in a few weeks so.. changing game objects or the way i get textures out of my SOs is just not what I want to be spending time on.. pretty soon AngrySharping is going to come out and put the hammer down

here I am, dealing with a sticky technical issue and my artist is like "hey I think we could get some benefits by redoing all of our texture library stuff what do you think"

[jolly token]

Lol yeah manually doing it wouldn't help

Just waste of energy

https://docs.unity3d.com/Manual/class-SpriteAtlas.html
Just add objects or folder then vola you have packed texture when built

[misty glade]

Maybe slightly off topic for this channel but thought I'd give it a go..

I've recently installed Storage Spaces in windows 11 and getting some pretty shit performance working in Unity. Looks like one of my drives is .. just fucking ancient and was a bad choice for throwing in the pool.

Any idea if I could sniff out what files are tending to thrash when I'm working in unity? I'm wondering if migrating my project files and/or unity to an SSD would help, or if it'll just be less headache to head down to Best Buy and grab a couple new drives and put them in the pool, taking the old one out as soon as the data's been striped over.

Nevermind.. looks like I found the culprit. Drive is limping.

[umbral brook]

is there a way to get the class that implements an interface from the interface?

[sly grove]

From the interface? No.

If you know what class it actually is, you can cast to it directly

[umbral brook]

kk, previously I have simply stored a reference to it but thught maybe there was a simpler way

wdym cast to it?

[sly grove]

This isn't an advanced question btw

Should go in #💻┃code-beginner or #archived-code-general

[umbral brook]

kk

[knotty sage]

I'm doing some work with CommandBuffers to render a thumbnail, had this working yesterday, today something has changed and my functions to set up the lights seem to have no effect.

I get grey lighting like this now.

Altering the global main light colour and direction doesn't do anything - I'm using "MainLightPosition", "_WorldSpaceLightPos0", "_MainLightColor" and "_LightColor0" to attempt to do this, called on the CommandBuffer object before rendering. The diffuse channel is also ignored, this looks like specular only and from the wrong direction.

Could this be some state related issue with uninitialized variables or something? I know that's unlikely in C# but the 'Graphics' subsystem seems state based, like OpenGL - perhaps something important is switched off or on depending on something else in the scene, which would explain why it worked one day and not the next (or I've accidently deleted something vital.. can't think what though!)

-edit-

This is all running off a scriptable object and with no scene but if I render an avatar in the scene and then run my thumbnail generator, it works. This suggests it is something stateful that's causing the issue but no idea what of course.

[mortal gust]

Is it possible to auto generate code based out of unity assets (e.g for each asset of a scriptable object type generate some code)?

[knotty sage]

sure, why not? It won't run at runtime though unless the C# compiler ships with the game and you can get all that to work.

[mortal gust]

Cool. I have it working by a inspector button right now but want it to work with roslyn, but couldn't find anywhere with the little research I did to fetch non code files. ^^

[knotty sage]

Cool I have it working by a inspector

[austere roost]

At the moment i have a system where i store global game variables (bool, int, string) to keep track of the player progression (if the player visited a particular location, if the player spoke to the npc and reached line 2 etc), to fire off other game events. Whilst this system is working, I would like to optimise it. At the moment i'm using 3 lists (bool, int, string) and i have a lot of duplication of code for adding/deleting/checking these. Is there anyway I can have some form of table that stores a <Key,Type,Value> to essentially have 1 central location? Or maybe someone has a different approach?

[dusk vine]

You can have list of object that would work with all of those

Or just string and convert bools and ints when needed

[austere roost]

i tried a list of object but the problem with that is that the value can only be one type (string) and then you have to either convert to an int or to a true/false value. it's very error prone

[lucid girder]

Should work:

List<object> myList = new List<object>();
myList.Add("Test" as object);
myList.Add(true as object);
myList.Add(1234 as object);
        
foreach(var a in myList) {
  Debug.Log(a);
}

[austere roost]

hmmm a custom editor would solve the "error" prone too... cheers

[lucid girder]

oh, and you can use GetType() to get the actual underlying type (string, int, bool etc)

[undone coral]

don't use GetType

don't use object

i think this is a code smell

you should create a class that strongly and clearly describes your game progression

[Serializable]
public class GameProgression {
 public Act1 act1;
 public Act2 act2;
}

[Serializable]
public class Act1 {
  public bool didKillVampire;
  public bool didVisitHouse1;
  ...
}

...

[austere roost]

i think i managed to do it using odin.
'''
[Serializable]
public enum VariableType {
Bool, String, Int
}

[Serializable]
public class GlobalVariable {
[SerializeField] string keyName;
[SerializeField] VariableType variableType;

[ShowIf("variableType", VariableType.String)]
[SerializeField] string stringValue;

[ShowIf("variableType", VariableType.Bool)]
[SerializeField] bool boolValue;

[ShowIf("variableType", VariableType.Int)]
[SerializeField] int intValue;

public GlobalVariable(string newKeyName, VariableType newVariableType, string newStringValue = null, bool newBoolValue = false, int newIntValue = 0) {
    keyName = newKeyName;
    variableType = newVariableType;
    stringValue = newStringValue;
    boolValue = newBoolValue;
    intValue = newIntValue;
}

}

public List<GlobalVariable> GlobalList = new List<GlobalVariable>();
'''

[undone coral]

you shouldn't be doing this in odin

you shouldn't be programming via inspectors

you don't need any of this. create a strongly typed class that describes your game progression

it's much, much, much simpler

and error free

[austere roost]

i'm not, it's just a pretty editor for ease of use within the editor, no ?

what's wrong with the above code?

[lucid girder]

The point of that was that the underlying type is still the same so you can get the correct typing out again when needed (by different means like casting, gettype, is etc)

[undone coral]

you are programming inside your inspector, because you're naming variables and setting their types in it

do you see that?

[undone coral]

focus on my good example

[Serializable]
public class GameProgression {
 public Act1 act1;
 public Act2 act2;
}

[Serializable]
public class Act1 {
  public bool didKillVampire;
  public bool didVisitHouse1;
  ...
}

...

[austere roost]

fair enough, i'll try that one

[undone coral]

do you see how this will just work

no

don't use gamevar

create a class that represents your game state

focus on this example

do you see why this is better?

[austere roost]

ok

[undone coral]

you don't have to create a custom editor for this. it Just Works

so it'll look nice in your inspector

although there's no reason to edit this in th einspector really

if you need to do something like the player killed the vampire

void PlayerKilledVampire() {
 GameController.instance.progression.didKillVampire = true;
}

that's it

that's all you need to do

do you see how much simpler that is?

[austere roost]

i do actually yes

[undone coral]

okay

get rid of the list of vars and such

don't do things that way

[undone coral]

also it's backticks not apostrophes to escape code

[austere roost]

:/ lol sry

[dusk vine]

no don't hardcode your game data 😦

[undone coral]

don't do things that way. this is also a code smell

[undone coral]

this is modeling the game data, not "hard coding" it

lots of wrong answers out of the gate today

[undone coral]

if you need code and data together, to represent e.g. an item, use a prefab

you can use a component to store the common aspects of the items. attach it to a prefab. then you can prefab-variant that, using it as a base for all your other items

[austere roost]

hold on, i see a flaw in the code above... everytime i want to add a condition, i need to modify the code? that is not at all what i want

[undone coral]

if there's item specific coded behavior, add it as a component

[dusk vine]

I'm smelling a troll

[austere roost]

i want these these "blackboards" to be modifiable on the fly

[undone coral]

every time you add a condition in ANY SYSTEM you will be modifying code

you can decide if you want your code to live inside inspector rollouts. if that's what you want, ask #archived-code-general

[lucid girder]

Just saying... even if something is "sub-optimal" it doesn't means it's wrong. Different issues need different solutions, and not everything needs to be super optimalized.

[undone coral]

you can have your code live in .cs files, in 1 line

[dusk vine]

@austere roost You can use generics to simplify the casting

[undone coral]

it's up to you

[dusk vine]

but I'd use gettype

[undone coral]

i mean you do understand* it's just a matter of intellectual honesty

[austere roost]

O_O

[undone coral]

do you know what i mean by program inside the inspector?

if you describe something like a "condition" or a sequence of actions that should happen, that aren't animations but are game logic

stuff like that. if you put it inside the inspector, you're programming inside the inspector. it's a bad idea

a lotta people do this not because it's a good idea, but because it stylistically feels good

[austere roost]

fair enough, thanks for the tip

[undone coral]

i have a feeling you're not going to do what i am saying

which is fine. if you want to reinvent variables, you can do that. you're calling them "game variables." and now you ahve to reinvent lists

you came here to ask for help in reinventing lists

do you see what i mean?

and reinventing types

you';re like "but my list, it holds bool, it holds string, it holds int"

and now a user is saying GetType

[austere roost]

i do have to say one thing... you're forgetting that not all game designers are pro devs... some game designers are exceptionally good at building a strong flow for a game but can't code... for those people, you do need an intuitive system for them

[undone coral]

you traded 1 line of code for what's going to add up to hundreds of lines of reinventing variables and lists

[austere roost]

something like this, solves this

that is super intuitive for a non dev

[undone coral]

you're forgetting that not all game designers are pro devs
yeah, so why are you embarking on reinventing lists?

[undone coral]

it's super intuitive to you because you wrote it

i think it looks horrible

[austere roost]

cool

[worldly imp]

Jesus Christ

[undone coral]

you can embark on this

you can do this i'm not stopping you

it's bad

you're not the first nor last person to do this

[austere roost]

do what exactly?

coz i'm getting kinda lost here now

[undone coral]

it really depends what this is for

[undone coral]

in my experience unity automatically packs these just fine

however with artists, it can feel good to be helpful, or to do the ceremony of "prepping" it for the technology... so this is more of an emotional call

[dusk vine]

@austere roost

` public class DataContainer
{
private Dictionary<string, object> gameData;

    public DataContainer()
    {
        gameData = new Dictionary<string, object>();
    }

    public void Add(string key, object o)
    {
        gameData.Add(key, o);
    }

    public T Get<T>(string key)
    {
        return (T) gameData[key];
    }
}

public class GameEvent
{
    public DataContainer myDataContainer;
    public void DoSomething()
    {
        if (myDataContainer.Get<string>("name") == "kevin")
        {
            myDataContainer.Add("TimesMetKevin", 1);
        }
    }
}`

[undone coral]

i don't think it will necessarily take much extra time. you will have to break it apart yourself in unity

[mortal gust]

My use case is a bit more complicated. If you know UE GAS system it's very similar. I want to create gameplay attributes and apply logic by inspector references. With this I also want to generate DOTS components and systems.

[knotty sage]

Does anybody know how to ensure a shader/material is loaded from C# code - this is running in editor, rendering using Graphics and DrawBuffers and the shaders don't seem to go through the 'cyan' loading phase or anything when going through that route.

so I need to force them to load

[undone coral]

what is your game?

[austere roost]

Cheers for this. I will take a look at it when i finish work and revert back. Thank you very much for taking the time to write this 🙂

[mortal gust]

FPS of sorts, why does it matter when I'm talking a generic gameplay system?

[undone coral]

i'm just trying to be helpful, it's useful to know what the game is

[dusk vine]

np 🙂

[undone coral]

usually

Is it possible to auto generate code
is a mistake

macros are mistake. if unreal were written from scratch today, it wouldn't have macros

i would at least start with that

[undone coral]

generic gameplay system
i think you should also accept that Unreal's GAS is not that generic

it's also not a super useful point of view and it will lead you astray

is your FPS supposed to be overwatch? like is that the idea?

@mortal gust truly first person shooter with spellcasters?

[upbeat path]

public DataContainer myDataContainer;
should be
public DataContainer myDataContainer = new DataContainer();

[undone coral]

like is that the design space*

is the design space the same as the design space of overwatch?

or is it the design space of counterstrike

counterstrike has like 4 grenades*

do you see what i mean?

i know what you're looking for

just try to answer the questions

simple yes or no: your fps, is the goal to have the same variety of things you could possibly design that players do in the game as Overwatch / Team Fortress 2?

it also doesn't matter from the point of view of the design space if it's multiplayer.

so it sounds like you don't know

which is okay

[mortal gust]

Yes, you can do different things.

[undone coral]

so overwatch?

[mortal gust]

I like the concept of connecting attributes in editor to create game logic.

[undone coral]

i think you're probably better off using Unreal to make an FPS. you're better off using Unreal to make a multiplayer FPS. and you're definitely better off using Unreal to make an FPS that also has the design space of overwatch. unity has essentially no robust approach to doing this.

there is simply no way to do this in unity.

that's why there are zero games that have ever shipped in unity showing such things

[undone coral]

well usually making an FPS, a multiplayer FPS, and a multiplayer hero battler FPS, these are super hardcore programmer dreams, not nodes and lines visual programmer dreams

[mortal gust]

V rising? I think this derails a bit from the problem.

[undone coral]

what is V rising?

you mean this game?

https://steamdb.info/app/1604030/graphs/

[undone coral]

i don't know, what do you want me to say? i'm giving you the perspective of an experienced developer

they probably suffered immensely during development* and their game is probably full of bugs

[brave viper]

Doc you're being overly confrontational here

[mortal gust]

I'm saying ability systems are not something new to unity, and I don't want to argue about it. I want to try to solve my issue, which is game independent really.

[undone coral]

you can use Source Generators

[undone coral]

well i'm not wrong

[mortal gust]

So are you saying source generators can see specific assets in the unity project?

[undone coral]

you can use an asset postprocessor

you can see how input system does it with the input actions assets

the source is open

good luck out there

[mortal gust]

Thank you : )

[undone coral]

i've implemented a "gameplay ability system." macros make sense in the context of unreal engine. i don't think the user should be taking this approach. it's just a really complex thing

it sounds like @mortal gust made no decisions about what it is he actually wants to make

it sounds like he wants to make editor tooling

i didn't ask directly what the goal is

maybe i shoul dhave

[austere roost]

He who? Me?

[undone coral]

even these stunlock studios folks, i'm sure they have a pretty big team and a complex backend. i don't know if they use a vendor solution like photon, and how

[austere roost]

The goal is to allow a non dev to essentially do puzzle logic in editor for a point and click adventure game where there's hundreds if not thousands of vars that are essential to shape the game story and progression. Did the player do this? Say this line? Pickup this item? Then this npc will reply with this dialogue... Just a little overview

[undone coral]

and with this sort of reply, you know, why ask here if there's no interest in learning

there are lots of opinionated content creators with youtube videos

it's not really a play along sort of thing

[undone coral]

well what's your goal? to make a point and lcick adventure game? we can talk about that

sometimes people get mad when i ask them what game they're making

the XY Problem is like, every QA discord ever

[austere roost]

Why would I get mad? I'll be off from work in a couple hours and I'll be glad to have a discussion about it.

I came in here asking for ideas not to contradict anyone 🙂

[undone coral]

well so what's the game

[austere roost]

A mix of monkey island and firewatch

Essentially

A very story driven "point and click adventure" but from a first person perspective (i know, it stupid calling it a point and click but there's no easier way to describe it)

[undone coral]

i think usually the best way to architect this kind of game is around an Ink script

and try to make the script as un-programmery as possible. like write a good script with interesting stuff happening first

more like a screenplay than a novel

like write the first first day of a firewatch style game*

you can also represent actions the player takes using ink options.

it already has variables

and lists

and all this stuff that is useful for representing state. imo you should be using state very very sparingly anyway

in a narrative game

@austere roost have you seen Ink?

[austere roost]

I have and did use it but it's super annoying to split up the logic, items, characters, locations etc from the dialogue and have an outside tool that has to essentially parse a json...super error prone and it's very hard to debug too.

I tried ink, twine etc ..they have the same issue

I make heavy use of scriptable objects in my game to store things like item data, character data, locations etc.

You want a new item? Just create an SO for it and it's ready to use anywhere

[undone coral]

okay

well i'll just say it really depends on what kind of game you want to make

there's an asset store kit for lucasarts style point and click adventures and also for first person hidden object game / walking simulators

it is very hard for a single person to make something immersive, it takes a lot of production values. super cost effective production values are more serendipity than something you can figure out from first principles. that horror game where you're driving around in a car escaping a giant monster comes to mind - it's serendipitous that vehicles are really well engineered in unity, and it's serendipitous that horror games are generally very dark, and it's serendipitous that it makes sense narratively that it's really foggy, etc. etc.

[austere roost]

Yeah I know about those but let's face it...if I want an opinionated fill in the blanks system, I'd do it myself how I want it not how someone else thought I would want it

[undone coral]

well i personally do not aspire to make asset store assets

[austere roost]

Neither do I haha

[undone coral]

so i basically never create custom editor rollouts

and i've been at this for a long time

this idea of someone being a non programmer - i mean, that has nothing to do with the kind fo game you're making

which should be a signal to you why i don't really want to engage in that

i don't think investigating "how to make something a non programmer can use" will lead you to a better or worse game, from first principles

nobody knows.

and opinions that are just "well wait until you find out the facts" are not opinions at all. you can certainly make an asset store asset that is "The Third or Fourth First Person Walking Simulator Building Tool" meant for someone other than you to use, then observe someone use it, and then be like, "oh i was right" or "oh i was wrong" but you will have still made no games

ink has been used in a lot of games

i like it because when i work with writers, who don't program

like hwy would a good writer want to open up unity?

a good writer never wants to open up unity

they like ink. it looks like a screenplay

it doesn't have nodes and lines. why are there nodes and lines dialogue editing tools?

why do so many games have terrible narratives? good questions.

it sounds like you want to make firewatch. firewatch, i'm sure, had a script

something that looked like a movie script. it is a linear game

they also had olly moss, maybe one of the most famous living pop art designers

so of course it didn't have to be dark. and the art* could be made by 1 person because it was a good looking non photoreal style

and i'm sure it still cost like $1m to make

campo santo is owned by valve now, but it's a big studio

it wasn't* made by 1 person. COULD it? maybe. so many serendipitous things

[sterile snow]

I noticed some discussion about "splitting up logic from the dialogue" and to be perfectly honest with you, you kind of have to (to some extent) if you want to make easily writeable and re-writeable dialogue

No one should ever have to open up source code to prod into strings like that

[burnt egret]

The less code you have to write, the better imo, so why bother with a thing you can't edit through the editor unless you have to, that's how I make games anyway

[undone coral]

i think the number of people on this planet who are both great writers and aspire to write for video games and not movies or books is very very small. it's kind of a moot point. in my opinion, if you're a single person, try to give the person who is making the narrative a tool that looks the most like Final Draft.

because there are way more people who are great writers who aspire to write screenplays

so they will at least know what to do

[sterile snow]

I personally am making a text adventure game because I'm both a writer and someone that specifically wants a fully interactive narrative game, and what I do is make every piece of dialogue accessible through many JSON files with a strict key naming scheme

Since most things are flavor text anyway this works well for me at least

And I can just drop new things into the JSON file and it'll work in a snap

[burnt egret]

I think if/when I start writing a story for a game, I'm gonna use yarn spinner

[undone coral]

hmm... you should probably use ink

[sterile snow]

May I ask what ink does?

I have something working right now but I'm open to new things to try to improve my workflow

[austere roost]

I think you're completely missing the point. Whilst I might not be as experienced as you, your perfect view of how things should be done is blinding you to many things and are assuming a lot. There are people who aren't devs. They're story tellers but have the ability to understand what a variable is. If I can pass a tool in editor that someone can iterate over different options for a puzzle without 1) learning how to write for ink or twine or w/e (which if you have used them, they're not as straight forward...it easy to mess everything up with a typo for example), 2) fast iteration, 3) they don't have to run to the dev to do something.

[undone coral]

it looks like a screenplay. it's a way to author dialogue and other screenplay-similar things for a game, where scenes can branch.

[undone coral]

i understand this point of view

just in my experience, "storyteller" is a flimsy thing

[austere roost]

Then you can also understand that the PERFECT solution, doesn't exist.

Because every situation requires a different solution

[burnt egret]

I will say, there's a reason why tool programmers exist, it depends on the scope of your project but anything that simplifies development is gonna greatly reduce the time it takes to make the game

[sterile snow]

Ah, I see. I'll have to take a look at this. In the meantime I just run off direct verb associations with dialogue (so something that triggers from "touch" would be keyed as "REACT_touch") and if I need to implement something specific or more controlled, I just override that verb trigger.

I dunno if any of this helps with the convo but it's what I do.

[austere roost]

Yup...and debug afterwards... For Firewatch they developed an in house localisation system for this exact reason. Their gDC talk is very insightful

[undone coral]

i can only talk about stuff that leads to making good games

since that's my goal

not stuff that lets you make any game

[burnt egret]

Give yarn spinner a look, not sure if your use case is applicable though since I think it's mainly for dialogue

[undone coral]

ther'es someone i work with who is building something similar around ink

[austere roost]

Which is also subjective. I hate games like Fortnite but their revenues disagree with my assessment lol

[undone coral]

and it works well

ink is nice because you can test it right away

[sterile snow]

Ahh

[undone coral]

it already has a working little thing that lets you play through your screenplay

[sterile snow]

I'll take a look, thanks!

[undone coral]

it's just a little creativity around how to choose options

that lets you do a "write a verb" style game that's backed by an ink script

but "write a verb" is still fundamentally making choices

and tbh, if you ever want it to work on phones, well no one is going to type verbs

[austere roost]

I did like both ink and yarn spinner but they all have the same issue. You write outside of unity in their language. You deviate a little bit and json doesn't compile.

They're brittle

Especially if you send the files to translation services

[burnt egret]

Yarn spinner has its own very simple programming language and I believe you can put event hooks into your story script

[austere roost]

Like they care to use a tilde instead of a dash

[burnt egret]

But idk never used it in production so

[undone coral]

i've sent my ink scripts to professional translators and they haven't really had any issues

in fact she liked that she could test the thing

right in the ink editor, which is just a text editor

then again i had a really good translator

it wasn't a service

[austere roost]

Well not every translation service is made the same hehe

Most just hire part time speakers that they send your file to and have no idea what it's for, let alone how or what unity is

[undone coral]

for solo developers, most are developing tools because that's what interests them

[austere roost]

Then you spend an eternity fixing the ink file just that it compiles properly

[undone coral]

anyway

[austere roost]

Anyway, gotta get back to work...thanks for the discussion:)

[undone coral]

you can try the game - https://monstermatch.hiddenswitch.com - this was built around ink

[austere roost]

Will do..cheers. catch you later

[mortal gust]

You told me to answer simple yes or no so I kept it short. I was also doing something else so had limited time to answer, but I greatly appreciate you trying to help^^
Would it be ok if I DMed you a bit more elaborate explanation when I have the time?
Cheers.

Does Unity Test Runner support expected exceptions?

[sage radish]

It's using a fork of NUnit, so you should be asking if NUnit supports it, which I'm sure it does.

[jolly token]

Assert.Throws

[flint geyser]

So my state machine has 2 behaviours for movement, one for player and one for mobs. Both inherit from IBehaviour and both use IMover to actually produce movement. How would I refactor them into decorators for another behaviour?
Why decorators instead of inheritance? Because my system isn't inheritance-friendly

[hardy nymph]

Hi I use this code to make a list of components and convert it into JSON form:

static List<string> getComponents (GameObject gameObject) {
    Component [] components = gameObject.GetComponents (typeof (Component));
    List<string> componentsList = new List<string> ();

    for (int i = 0; i < components.Length; i++) {
        string json = EditorJsonUtility.ToJson (components[i]);
        componentsList.Add (json);
    }

    return componentsList;
}```

It's working fine but I want to ignore the private fields in it

How can I make it ignore private fields ?

[sly grove]

Bad idea. Just make one object that has a list in it and serialize that

Why are you using EditorJsonUtility?

Just regular JSONUtility

[hardy nymph]

It's an Editor script, it runs while the game is not running.

[sly grove]

That's ok

Use the regular JSONUtility

If will ignore private

Unless serialized

[modest lintel]

EditorJsonUtility serializes the actual component data, which is pretty cool

[hardy nymph]

It's giving me some error

ArgumentException: JsonUtility.ToJson does not support engine types.

[sly grove]

What are you trying to serialize exactly

Wait you're trying to directly serialize components? Why?

What's the goal

[hardy nymph]

Originally I wanted to send the object + component data to the web. On the web I have an interface for editing them in real-time:

Previously I was converting entire component data into JSON and displaying that on the web (including the private fields), when changes were made it sent the updates JSON data and Unity duplicated / created a component from it.
Now I want to display only public fields.

[modest lintel]

Could be alternate approaches, but via reflection you could get all the public fields and find the intersection of those and the fields present in the json

[hardy nymph]

I don't know about reflection, where can I learn about it ?

How would I rotate an object to match the normal of the surface beneath it? I'm trying to build a spider that can walk on walls. When it walks onto a surface with a different angle than it, I want the body to reorient to have up be the normal of that surface. I know I can get the normal with a raycast, I just don't know how to construct a quaternion based on that.

[west scarab]

transform.up = normal

[sage radish]

You can set spiderTransform.up = surfaceNormal, but that's shorthand for creating a Quaternion from the direction and setting the rotation. It looks something like this:

public Vector3 up
{
    get => rotation * Vector3.up;
    set => rotation = Quaternion.FromToRotation(Vector3.up, value);
}

[livid dawn]

That's fantastic, thank you.

[west scarab]

If you only want to create a rotation from a direction, you can also use Quaternion.LookRotation, which as an overload for specifying both the "up" and "forwards" vectors

Up in that case would be your normal, with forwards probably being the spider's transform.forwards I would guess

I'm working on a compute shader voxel raycaster and for some reason when I pump up the voxel count the Unity Editor craps itself. It runs just fine in a build but in the editor it runs at 1 fps. I know this is kind of a shot in the dark but what could possibly becausing this?? I was showing all the voxels in an array in the inspector but i used HideInInspector to get rid of it now, and I don't have any other large arrays or anything being displayed there.

project is basically empty, only 4 objects in the hierarchy in total

no debug logs either

oh... now it stopped running poorly??

restarted and now it runs poorly again. what

maybe HideInInspector isn't enough?? guess it needs to be not serialized

yeah that was it thanks bros

[humble onyx]

wired thanks for sharing the issue

[undone coral]

can i author a roslyn analyzer right inside unity? how?

[ancient talon]

I find it odd that having visible component exposed in your inspector (Or even having the component visible within the editor) can affect your performance badly.

[jolly token]

I don't think so. You need to build it into dll

[hollow veldt]

Was NativeList renamed? I can't seem to find it in Unity.Collections

[dire solar]

You need to install ECS for it to show

[hollow veldt]

I've just done that but I don't see it still. I'll try regenerating the solution...

IMO NativeList should be a part of Unity.Collections

[dire solar]

I agree! Also, if you're using assembly definitions, make sure you have Unity.Collections asmdef included

[hollow veldt]

💯 regenerating the project files worked

thanks!

[blazing verge]

Is there a way to switch between urp and hdrp at runtime?

[regal glade]

This happens when you have millions of entries in an array that's visible in the inspector

[dire solar]

I'm currently using IJob to compute the minimum value from a given NativeArray<int>. Is there a way to speed it up? I tried IJobParallelFor but had race condition issues.

Edit: Solved using IJobParallelForBatch

[scenic forge]

What's the scale?

[dire solar]

1+million values. I'm experimenting with two jobs (IJobParallelForBatch + min/max queue) followed by (IJob + min/max singular value that iterates over the queue). This is much faster (and works!) than a singular IJob, so thats cool

[scenic forge]

You could look into splitting the workload into multiple chunks and have each thread deal with one, then a final min for results from all threads.

[dire solar]

Precisely, IJobParallelForBatch came in clutch.

[scenic forge]

If possible, process them while they are produced might also be good, especially if the producer is already using multithreaded jobs.

[west scarab]

What does your execute code look like?

If you want it to be even faster you could try reinterpreting your NativeArray<int> to NativeArray<int4> so the burst compiler can better parallelize the instructions. It might already be doing it though, depending on how you wrote it

(you'd have to check the generated burst assemblies)

[icy aspen]

Can someone please explain how this is possible?
As you can see, I have two time stamps (one in the active ghost and one in the ghostrecorder component)
When I set the activeghost timestamp (timestamp is a list by the way) to the ghostrecorder timestamp, and clear the ghostrecorder timestamp, the activetimestamp somehow is also cleared

[fresh salmon]

Because the time stamp is a reference type.
From the usage it would be a List<T>.

[icy aspen]

huh, what do you mean

[fresh salmon]

The variables point to the same place in memory. If you modify the first one, the second will have the modifications.

Passing them around with = does not make copies of them

[icy aspen]

ohh

that makes sense

so, how should i make a copy of it then

because that's what i want to do pretty much

[fresh salmon]

First things first, is it a List?
