[frozen ravine]

yeah

but I'm doing shader graphs for my UI elements so I needed to upgrade

since fsr it took them that long to realize they needed it lol

does anyone have an answer to this? I've been stumped for a while on it

[dapper cave]

rah TMP is such a pain in the ass, I know ppl had to poke at the hlsl

[frozen ravine]

frick

[abstract folio]

I'm having some trouble with package dependencies. I'm trying to get unity package manager to automatically install the dependency (LimitedObjectScrollList) from git, if not present, when installing the dependent (FilePanel) package from git.

But when I try this it gives me an error saying it cannot find the dependency.

I've tried a whole bunch of variant urls, as I'm pretty sure the problem is in the dependent's manifest file, but I'm just kinda guessing and finding conflicting info on what URL I SHOULD have in there.

Can anyone set me straight?

here are the relevant files...

Dependancy package
https://github.com/glurth/LimitedObjectScrollList/blob/main/package.json

Dependant package
https://github.com/glurth/FilePanel/blob/main/package.json
https://github.com/glurth/FilePanel/blob/main/manifest.json

[frozen ravine]

I found the hlsl file that it uses, but I'm not really that good at hlsl, if there was a way for me to use a graph, that would work

[dapper cave]

TMP usually don't need much noodling, what are you trying to do? maybe you can layer

[austere jewel]

Installing via git doesn't read dependencies afaik. It's not a package registry so it'll just be ignored

[frozen ravine]

I made a Chromatic Aberration shader and I'm trying to make a TMP version of it

I know I could just cheat it by making 3 different text objects or something but this solution should theoretically be able to apply to any text object since I'm gonna be using it a lot

[austere jewel]

The TMP shaders are all there in your project and you can happily modify them. But they're using SDFs and have tons of layers, so it's not easy

[frozen ravine]

I found the shader that I need to base it off of and it's not actually even that long, I just have no clue how I would change it since I'm not that good at HLSL

[dapper cave]

should be pretty easy to hlsl that thing, just copy the 3 RGB offset to the end, just before it returns the pixel value

[abstract folio]

it does seem to know about the dependancy from the json file- and it show up in package manage.. but sounds like that's insufficient, even if I give it the github url? darn.

[austere jewel]

But how do you know what value is next to yours to do this RGB offset

[dapper cave]

something like
out = sdf stuff
out = mangle out with RGB offset
return out;

[dapper cave]

was thinking uv offset

[frozen ravine]

it's split into 2 functions, PixShader and VertShader. For a TMP object, would it be Pix? I don't think I'm modifying any vertices

[dapper cave]

oh but that'd need an output to some rendertexture... meh yeah that won't work

[frozen ravine]

yeah I think it would be idk why I asked lol

is there any way to use my sub-graphs on a regular shader?

[dapper cave]

that's a question for jason boothe, he'll go on half an hour rant then will prob tell you nope

[frozen ravine]

lol

well I guess I'm learning more about HLSL now

fun.

man I've spent like 5 days at this point on this single UI lol but at least it's gonna be really polished

[dapper cave]

bloody pain in the ass: it's like Unity don't like easy stuff anymore, everything is so tortuous

[dapper cave]

5 days for this isn't worth it, either you do what you said and tripple your TMP, they're cheap anyway, or you render them to a 3D camera and put a RGB offset post effect on that

[frozen ravine]

well I haven't spent 5 just on this part, but the whole UI

I've made like 8 shader graphs for this UI already, a Skew component that skews any TMP_Text or Graphic, and spent 2 days alone just doing the design and doing a bunch of iterations

[dapper cave]

oh ok

[frozen ravine]

the Skew component alone was a pain in the but lmao

since TMP doesn't use the IMeshModifier like all the other Graphics do

here's how the whole thing looks so far

[dapper cave]

doesn't? it's all in SDF shader?

[frozen ravine]

there's no way to skew TMP built-in and it doesn't have the same way to modify the mesh like Graphics do (even though it is a Graphic)

[brisk pasture]

could skew it in the vertex shader?

[frozen ravine]

I could, but I'm intending to have other shaders like the chromatic aberration one I'm trying to make so I wanted to make it a component so I could just slap it onto something that needs its shader

[dapper cave]

yeah, stack a vertex shadergraph on top of the sdf thing

[brisk pasture]

why would chromatic aberration be applied to the mesh

thats something you will be doing on the whole screen

[frozen ravine]

not the mesh, the Images

I also have a Glow shader which some things will be glowing but also skewed so if it was a shader, I couldn't do both since Images can't have multiple materials

[brisk pasture]

it really sounds like you are implementing thigns into the per object shaders that really should be done in post processing

[frozen ravine]

how would I do skewing in post-processing?

and why would I?

[brisk pasture]

like glow i would just do via bloom, with a above 1 threshhold

[dapper cave]

maybe he wants a per button effect

[austere jewel]

If you were publishing it for the public I would use OpenUPM. But you really need to add some Readme's

[brisk pasture]

the skewing the characters i would do on the shader that is applied to the TMP object

[frozen ravine]

yeah but I think that's a bit more expensive and also not as customizable

the bloom doesn't give the effect I want

I want a Photoshop Layer Effect-style glow

[dapper cave]

expensive is late stage consideration, unless your hardware target is something weak.

[frozen ravine]

I wanna be able to target as many computers as I can

[dapper cave]

yeah don't worry about it dude, that's a form of procrastination

[abstract folio]

OpenUPM.. cool will check that out, thank you.

[dapper cave]

just do your thing for a 2060 target then optimize if players complain

or you're never done noodling

[frozen ravine]

I mean it didn't take that long and I still think it's better than the post-processing approach

[dapper cave]

Quest 2 would be another story, PC, players are used to shit framerate

[frozen ravine]

this lets me put the shader on things specifically rather than just everything that has a high glow

[dapper cave]

you can mask out stuff

[frozen ravine]

yeah but I think that's a bit more troublesome than this approach

this is just putting a shader on things, versus having a layer for what needs to be glowing

[dapper cave]

ok

[frozen ravine]

also that glow shader took like half an hour, it didn't take as long as the other stuff

[dapper cave]

weird, my 2022 won't compile on script change by default, where is that setting?

[frozen ravine]

I'm taking a poll: Should I rotate the items in the shop, skew them, or have them be flat (no rotation or skew)? Pretend the image with skew has shadows like it's supposed to lol

[bleak citrus]

This is not a code question.

[dusty wigeon]

Personaly, I would go for a simpler approach if what you tried havent work such as redesigning the UI.

[frozen ravine]

True

[frozen ravine]

How so?

[dusty wigeon]

Remove the necessity to skew the text.

[frozen ravine]

So you think it shouldn't be skewed or rotated?

[dusty wigeon]

If you are not able to make it in a reasonable amount of time, yes.

[frozen ravine]

Well I mean I think it would be easy, I just have to remove the skew components from everything, but I like having some sort of motion to the design. I'll still consider it when I get the results of the poll though

I'm trying for something like persona but less crazy

[dusty wigeon]

The time you use on this aspect could be used else where. It really a question of how much you want it or not more than what is better in my opinion. (Given that you seem to struggle to make exactly what you want)

[frozen ravine]

I don't really struggle, it just takes a while since Unity doesn't have the Skew as part of its transform already. Now that I have the component, I can skew anything so time really isn't an issue. I've been working on this project for a while and fully anticipate to spend a lot of time polishing it as much as I can

If I have a goal, I'm gonna achieve it. I'm not gonna settle for good enough just because it takes less time

This is pretty much almost exactly how my Figma design looked

[dusty wigeon]

That is really not a good way to approach game development, but you are free to do whatever you want. We all have different view, but keep in mind that you sacrificing a lot in pursuit of perfection.

[frozen ravine]

How? I want to make a good game and I know how to do the stuff. Polish is one of the most important parts of a game

I have a timeline to complete the game by and I'm still approaching it steadily

[brisk pasture]

skew is a simple matrix multiplication in a vertex shader. but i think what simfoerce is trying to saying is you should move on and get the whole flow of the game going. before trying to apply alot of polish to 1 small part

[dusty wigeon]

Do you not realize that everything has a cost. When you are doing a specific things such as that, you might leave other more important aspect. This one of the main reason why a lot of people tends to abandon project midway.

[frozen ravine]

Well I know it's simple in matrix multiplication, but I had to do stuff with TMP meshes and I couldn't just manipulate the transform matrix. I'm trying to make a vertical slice, not a horizontal one

It's not leaving the other aspects, it's just doing one thing and completing it before moving onto another

This has only taken me a few days, it's not like it's taken weeks

I probably won't have to spend more than a couple more days on it, if even

If I had spent like a month on it then I could see your point, but the amount of time I've spent on this compared to the other stuff is very small

This is by far not the only part of the game I've worked on

And while I'm working on this, the rest of the team is still doing their thing so it doesn't halt production of everything else

[dusty wigeon]

I really hope you just reflect on what you said.

The following is simply wrong on many level in my opinion:

It's not leaving the other aspects, it's just doing one thing and completing it before moving onto another

What you have done could have been such things that are not important (I do not have all information on hand), I was simply giving advice on how to manage your project base on what I understood of your question. Anyway, it seem you get it.

But sure, it is also important to keep in mind that a game is a collection of little details. Just keep in mind that everything has a cost.

What is the best way to force a pixel game to act as if it's on a specific resolution (i.e. 384x216) but still fill the whole screen regardless of what monitor resolution it's played at, while not messing up the UI?
Reason I ask is I've noticed Text doesn't align perfectly with most of the methods I've tried. It ends up having some floating point error and ends up off of the pixel grid I'm trying to establish. Normally not noticeable, until the Text is next to or on top of an Image.
Unless I build the project in 384x216 windowed mode, then it's on the grid. Only problem is its tiny on any modern display, so that's useless for what I need.

The font is a bitmap font, so it should be pixel perfect. I've tried other bitmap fonts and have gotten similar results, so I know it's not the font. It's something about how Unity places Text when the screen size of a pixel isn't 1x1, but instead 5x5 or some other scale.

To show what I mean, here's a test screenshot in a build, where I overlaid a checker pattern that matches the intended resolution. The background neatly is aligned, as are the buttons, but the Text in the buttons on the right is not aligned. No matter what anchors, positions, or alignment I set on the Text, it's not behaving.

The 'About' button (4th down) comes closest, but zooming in shows it's got some slivers of a pixel showing on the b on o that shouldn't be there

[novel plinth]

Did they remove the mono.simd.dll from the editor now? if so, proly it won't be compatible anymore if I'm going to borrow it from official mono?

[flint wind]

Hacky workaround ended up not involving any recoding of anything, but to use a magic number of 1.0125 for the line spacing, to counteract what unity was doing in the Text component

[sharp verge]

Can someone give me a example of how to convert reflection.MethodInfo to unityevent, I just couldn't get it to work thanks in advance

[brisk pasture]

that is a bit of a weird ask, what are you trying to do

also you could just make a lambda that calls invoke on your method info

_myUnityEvent.AddListener(() => _methodInfo.Invoke(target, args));

i do this in my game for my cheat menu, have a CheatAttribute i add to things in need in the menu, and it builds it via reflection for me

[sharp verge]

im so mad ,i fogot that AddListener wouldnt update the inspector but it is added🤡

[terse oyster]

Hi! Does anyone know how to get all scores from a bucket leaderbord in js unity cloud?
I use const getScoresResult = await leaderboardsApi.getLeaderboardScores(projectId, "LDBBucket"); and the result: "detail": "Score submission required to view the scores of this leaderboard",

[vague raven]

Hi, i have a very niche problem, i am not a good coder, I am trying to make a deformable terrain using the Unity terrain system. The system uses a height map stored on the computer to make the height of the terrain. my aim is to create a mining system in which you use a ray cast to target the ground and that will then deform the terrain at the point. However, the nothing i am doing seems to work. I can link the code if that helps and im just getting a bit lost. I am able to get the data from my point on the terrain but i cannot use that data to then deform the terrain.

[verbal temple]

you should provide the code, but also, if you are using the terrain SetHeights method, keep in mind that the heights passed in need to be numbers from 0 to 1 and not a actual heights.

[vague raven]

private void Mine(Vector3 point)
{
int mouseX = (int)((point.x / terrainData.size.x) * heightMapRes);
int mouseZ = (int)((point.z / terrainData.size.z) * heightMapRes);

    float[,] ModifyHeight = new float[1, 1];
    float y = heights[mouseX, mouseZ];
    y -= strenght * Time.deltaTime;
    if (y < 0)
    {
        y = 0;
    }
    ModifyHeight[0, 0] = y;
    heights[mouseX, mouseZ] = y;
    terrainData.SetHeights(mouseX, mouseZ, ModifyHeight);
}

This is the code that effects the terrain but i cannot figure out how to get the height function to work be between 0 to 1.

[verbal temple]

I believe you want to divide the result by your TerrainData's heightmapScale.y before setting it

so, in other words, translating from normalized height to real height (and back) would be like

var terrainHeight = terrainData.heightmapScale.y;
var realHeight = heights[mouseX, mouseZ] * terrainHeight; // from 0-1 to 0-terrainHeight
var newHeight = realHeight - strength * Time.deltaTime;

heights[mouseX, mouseZ] = newHeight / terrainHeight; // from 0-terrainHeight to 0-1

[solar parcel]

Anyone know of a good way to call a method on a script once an animator state finishes? Preferably without using animation events since adding them to each animation isn't really an option

[brisk pasture]

could use a StateMachineBehaviour

[upbeat path]

AnimatorStateInfo

[solar parcel]

yeah but unfortunatly they cant access the scene and I want this to be as general as possible

[solar parcel]

I will look into that

thank you

[brisk pasture]

they kinda can actually, since you have access to the animator from them, which can get stuff on the same object as it

otherwise you can read the state info in a update and wait for its change

[solar parcel]

well yeah but what i want is for the method to be selectable from the inspector

and the animator reference only exists during runtime

[brisk pasture]

so read the AnimatorStateInfo,

detect when it changes and execute what you want

[solar parcel]

okay i will try that thanks

[hardy jacinth]

how do I initialzie newly created scriptable object, to have it reference some other assets without manually selecting them everytime an SO asset is created in the project?

I've searched through the web and no help found

[flint sage]

It probably works if you select the SO file and then change the values on that instance, that should serve as defaults

Or you can create your own custom creation function that sets things

[hardy jacinth]

I mean during the first asset creation in the project

[hardy jacinth]

yeah, like that. But where do I write it when I have a SO attributed with [CreateAssetMenu]. I saw one answer with custom editor and doing it the OnInspectorGUI, but I fear it won't trigger if the inspector is closed.

[flint sage]

Don't use CreateAssetMenu

[fresh vortex]

why not?

[hardy jacinth]

[ContextMenu] that is then, I guess

[hardy jacinth]

probably because it doesn't seem to have any exposed mechanism for something like "OnAssetCreated"

[flint sage]

If you want to do custom behaviour on asset creation, then you have to implement it yourself

IIRC if you check the reference source, you can find their implementation and copy it

[hardy jacinth]

I didn't find anything that happens on asset creation. For example on this page, Initialize has to be manually called from [MenuItem], that is by using UI to assign asset defaults... which sounds pretty dumb https://docs.unity3d.com/ScriptReference/ScriptableObject.html

for now I did it like so:

public class Preset : ScriptableObject {
  private void Initialize() { /* initialization of defaults here */ }
  
  // based on mechanism from shader-graph package
  [MenuItem("Assets/Create/...")]
  private static void CreatePresetAsset() {
    ProjectWindowUtil.StartNameEditingIfProjectWindowExists(0,
      CreateInstance<CreatePresetAction>(),
      "preset.asset", null, null);
  }
  
  private class CreatePresetAction : EndNameEditAction {
    public override void Action(int instanceId, string pathName, string resourceFile) {
      var preset = CreateInstance<Preset>();
      preset.Initialize(); // <-- initialize once
      AssetDatabase.CreateAsset(preset, pathName);
      AssetDatabase.Refresh();
      Selection.activeObject = AssetDatabase.LoadAssetAtPath<Preset>(pathName);
    }
  }
}

[hardy jacinth]

I guess you mean scriptable wizard, not scriptable editor?

[hardy jacinth]

yeah, that's called a wizard: https://docs.unity3d.com/ScriptReference/ScriptableWizard.html

But that's not what I need. I have some fixed defaults and all the other things are just created at use-site. The wizard adds a bunch of needed complexity to that. this works OK for now.

there is another problem though, when I update something in my SO, other assets that depend on it don't refresh in editor.

[abstract folio]

https://docs.unity3d.com/ScriptReference/ScriptableObject.Reset.html this guy should get called when the object is created.

[proven halo]

I'm having an issue where some fields of my class are not serializing, while others are, and I cannot figure out why. The fields in question are public, and are simple types like float and bool. Any ideas why some fields would serialize, and some do not?

[sly grove]

Do you have any compile errors in the console, for ANY code (not just this code)?

[proven halo]

nope

[sly grove]

Then show your code and explain which fields aren't serializing and how you checked if they are or aren't.

[proven halo]

Ah I got a field to serialize, althought I don't fully understand why it wasn't before.
I have a separate editor script, and for the fields that were working properly, I was doing
EditorGUILayout.PropertyField(serializedObject.FindProperty("myField"), new GUIContent("Label", "Tooltip"))
For the fields that were not serializing, I had used a different way to add them to the GUI:
MyClass myObject = target as MyClass;
myOject.myField = EditorGUILayout.Slider("Label", myObject.myField, 0.0f, 1.0f);

After switching everything to the first form, it is serializing properly

[thin mesa]

that's not an issue of the field being serialized, that's just it not being drawn in the inspector due to your custom inspector for that object. the field was still being serialized despite not being drawn in the inspector

[proven halo]

The fields were in the inspector in both cases, and changing the slider affected my object in both cases, however, saving the scene and reloading it would lead to the fields using the second form to not have the correct value, they were always reset to their defaults upon reloading the scene

Looks like the reason was actually because I was not calling EditorUtility.SetDirty(); in the second case. So the fields would have serialized just fine, but I wasn't flagging the object as dirty so I guess they never got serialized

[proven halo]

Seems like using the EditorGUILayout.PropertyField() method calls SetDirty automatically under the hood

[sly grove]

Yeah this isn't a lack of serialization, you just didn't mark the SerializedObject as dirty. The fact you were using a custom editor would have been pertinent information when asking the question.

[proven halo]

Indeed. Luckily I was able to figure it out after rubber ducking here.

[proven halo]

Honestly I am not sure what your response adds to the discussion here. You summarize my own findings back to me as though it is new information. If I had known that the custom editor was part of the problem when asking the question, I would have included that. But thanks anyway!

[sleek moat]

I'm using steamworks, and I can't figure out how I would kick a player. What I've tried doing is when someone clicks the kick button, it fires a ClientRPC, which then all clients get it, and if they have the CSteamID that was sent in the ClientRPC, then they will call SteamMatchmaking.LeaveLobby(), but it doesn't seem to work, and I don't want to put a NetworkIdentity on the gameobject holding it.

[stuck plinth]

not sure i totally understand the problem here, is this NGO with steamworks or some other framework? in NGO you can send a custom message if you want to send a messaage to all clients but it's not related to a specific network object

[sleek moat]

What is NGO?

[stuck plinth]

unity netcode for gameobjects

[sleek moat]

I'm using FizzySteamworks w/ Mirror, and using netcode for gameobjects too

[stuck plinth]

ok, sounds like you want a custom message then?

[sleek moat]

Yeah, someway to send messages between them.

[stuck plinth]

oh i mean the actual feature named custom messages: https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/message-system/custom-messages/

[sleek moat]

But does this require any Network Components on the object recieving/getting custom messages?

[stuck plinth]

there's no object involved, custom messages is a system totally separate from rpcs

you just need a reference to the network manager somewhere!

[sleek moat]

Ah ok, could I pass parameters through it such as a CSteamID

[thin mesa]

why and also how are you using two networking libraries? 🤔

[sleek moat]

Maybe I'm confused, but I think I meant I'm using Mirror's network objects

[stuck plinth]

you can send whatever you like really, but with custom messages you have to do more of the reading/writing yourself! steam ids are just a number though so that should be no problem

the docs have some examples of using FastBufferWriter/FastBufferReader

[sleek moat]

I think they are a type of ulong but I don't really know

yeah its a 64 bit ulong it says

[stuck plinth]

yup!

[thin mesa]

okay so that is not unity's Netcode for GameObjects package. so you'll want to check mirror's docs to see if they allow custom RPCs like n4go does

[stuck plinth]

steamworks is matchmaking, mirror is the transport, ngo is the framework

[sleek moat]

Well actually

Fizzysteamworks is the transport

for me

[thin mesa]

mirror is a networking framework akin to ngo. it's based on unet

[sleek moat]

I got to go now, but thanks for the help simonp. I'll look into it soon.

[half swan]

Mirror was named that because it is a "mirror" of unet afaik

[stuck plinth]

🤷 i don't understand this stack at all then, luckyecho you should probably check whether you're actually using mirror or ngo lol

[sleek moat]

Mirror as the transport, using NetworkManager from mirror, and FizzySteamworks for multiplayer

[thin mesa]

mirror is the network library, fizzysteamworks is the transport https://mirror-networking.gitbook.io/docs/manual/transports/fizzysteamworks-transport

[sleek moat]

Thats what I am meaning.

[stuck plinth]

i guess this is what you want then https://mirror-networking.gitbook.io/docs/manual/guides/communications/network-messages

Regarding Asynchronous loading of assets via AssetBundles, if I asynchronously load an asset, and said asset has dependencies (such as containing an array of unity objects), do these dependencies load asynchronously as well or synchronously?

[grizzled valve]

Hi, is there a way to get all defines that will be applied in the build, prefferably during build pipeline or right before it?
I know i can use PlayerSettings.GetScriptingDefineSymbols - but that only gives those that are explicitly defined by user, it excludes the unity build-in ones like UNITY_ANDROID or unity versions etc.
there is also EditorUserBuildSettings.activeScriptCompilationDefines but that returns the current ones, so if i build different target then the current one then its not correct. Also when i apply PlayerSettings.SetScriptingDefineSymbols just before checking activeScriptCompilationDefines then its not up to date and i have no idea what callback to wait for so i get the correct ones.

I was thinking if maybe someone knows some unity callback that will give me the defines so i can write them to build somewhere.

[gleaming rock]

Hey guys, I am far into multiplayer fps game development with Unity. I have been lately debugging my lag compensation code and it looks like one box collider is offseted little bit on server in comparison to client. (or my box collider drawing code does not work)

I am drawing using object's (which got the collider) position, rotation, lossyScale, and also box collider size + center. It also seems like lossyScale is different by about 0.001 even though it should be (100, 100, 100) on both.

My question is: how can I 100% accurately log a box collider into console? Do I just need box collider's center & size, and then the object's world to local matrix, instead of using lossyScale etc?

[random dust]

Sounds like inaccuracies with float objects?

If you want it to be super precise you might be able to instead pass a decimal value rather than a float type

[gleaming rock]

I don't think that is the case.

My player got the following box colliders: head, legs, arm1, arm2 and torso
it seems like only torso's position/rotation/scale is offseted little bit. all other colliders are pixel perfectly where they should be.

[mellow plinth]

Two questions:

1. Is there a way to know if my code is run inside a Unity Job?
2. Is there a way to know if my code is run inside Burst (even if it's not actually Burst compiled, ie: a managed code called from Burst using function pointers)?

The question is because I want to call a method when possible that can only be called in the Unity thread. And if we are not in that thread, I want to not call it.
I was checking the managed thread id and the synchronization context, but this doesn't seems to work all the time, at least for the (2) point it doesn't work.

[stuck plinth]

can you put the unity-specific part in a method annotated with [BurstDiscard]?

[mellow plinth]

[BurstDiscard] only works if the method is compiled with Burst. But if you have a burst-compiled method, which performs a function pointer call, you can call managed methods which are not burst-compiled

[stuck plinth]

ohh right i see... what didn't work with checking the managed thread id?

[mellow plinth]

It didn't, I don't understand why but checking the managed thread id seems to not be enough

🤔

[stuck plinth]

what do you mean it didn't work though?

[mellow plinth]

I tried to compare current managed thread id with the main one, and if different, not call the Unity method.
But when called from a managed method, called as a function pointer from a burst-compiled one, the function is still called and it throws a not catchable exception.

[stuck plinth]

hmm, i guess because jobs aren't running on managed threads 🤔

it would probably be easier to pass the information through from the burst job if that's an option, if you can add a parameter to the function pointers being called? then you'd be able to use BurstDiscard etc

[scenic forge]

Not exactly an answer to your question, but maybe have two versions of the code, one for Burst one for not. Code duplication can be solved just like any other code, by extracting and reusing the common parts. Might be easier even if less elegant.

[brisk pasture]

there is also no problem with a bit of code duplication and if means less other problems to solve

[mellow plinth]

I guess I could have two methods, but the idea was that the consumer of the method doesn't need to know where it's currently running

[kindred wyvern]

I've had enough.

public static Object ReliableReference(this Object obj) => obj == null ? null : obj;
public static Object RR(this Object obj) => obj.ReliableReference();
```_I'm taking my nullity operators back._

Wasn't sure where to put this but i'm making a Unity plugin packaged as a .dll and I was just curious if anyone knew of a way to trigger an assembly reload in an active unity editor instance via a postbuildevent

rn i copy over a build to my unity project as a post build event and in a perfect world it would be cool if i could tell it to start reloading at the same time yknow

[tawdry sentinel]

I THINK this is advanced? Not sure XD
I've basically stuffed an array inside of another array. One has a size of 7, the other has a size of 6. And what I do with these is I calculated a semi random coordinate for an island on my map, stuff the coordinates, name it, and attach an object and an image to it. My problem is, I have no clue how to save it. Because PlayerPrefs only saves ints, floats, and strings. I'm being told I should save it using a json and save that as a string. But that has come out as not working lol.
This paste bin contains all the main functions
https://pastebin.com/KD2kKmC6
"Quick" explanation:
When the game starts the first thing that runs is the SaveManager. Which on awake loads any saves and sets the variables within SaveManager, to those saves.
THEN MapController loads, and in the start function it sets the islandArray as the islandArray from the SaveManager. If it turns out to be null or 0 (no saved islandArray) then it creates islands and saves that array. I've added a couple debug logs checking the length of the array to make sure it's not null or incorrectly saved.

After running and closing the game twice, my debug logs show that when the islandArray is loaded in the SaveManager the length is 0. So then MapController goes to create new islands, does so correctly. Then when it attempts to save the array, SaveManager says the array taken from MapController has a length of 7, which is correct. And for redundancy I checked if the islandArray in SaveManager after setting it's value to the value of the islandArray in MapController is the same, and it is, 7.
But even though the saves SEEM to check out, at least the lengths of the array, the length never checks out when loaded/transferred from json

Please help XDDD

[brisk pasture]

its a limitation of json utility

can use the Newtonsoft Json Unity Pacakge

its much more full featured

also i would not save it to player prefs

https://docs.unity3d.com/ScriptReference/Application-persistentDataPath.html

this gives you a path you can save files to and read from

[tawdry sentinel]

yayyyyy more learning XDDD
Time to learn how to manually create a file that I can put an array, and turn back into an array XD fun times

Thanks lol

[brisk pasture]

File.ReadAllText and File.WriteAllText

just have to build the file paths from the persistientDataPath and your file name

[tawdry sentinel]

Oh, easier than I thought

Thank you ❤️

[untold moth]

Or reorganize your data structure to not use an array of arrays. Or serialized it manually.

[brisk pasture]

if its simple for 2d grid data or something similar

its possible to use a 1d array, and some math to convert a x, y coord to a index into it

[tawdry sentinel]

I just decided to go with 2 arrays because I need the inner array to contain a string for the island name, it's coordinates relative to my 2D map, and the game object and image object it's attached to. And then ofc I need multiple islands, so I need that array to be inside another array.

Unless I'm just making my life harder on myself

[brisk pasture]

if the width of the map is knowen its possible to use 1d

i = row * colCount + col

would let you take a target row and column and get a index into a 1d array for

[jade solar]

I'm dealing with pointers/memory addresses and having an issue with just doing it right. I keep on getting an error telling me that a field initializer cannot reference the non-static fields, method, or property Hoverboards.test. I don't know of any other way to do this.

[long ivy]

well, the error tells you what you need to do. Which is not reference non-static fields, properties, or methods in field initializers. Use a constructor. Your snippet is nonsensical anyways

[jade solar]

But I've written code like this all the time:

[long ivy]

? Value isn't a class field there, apples and oranges

[jade solar]

That makes a lot more sense now. Thank you.

[valid shale]

You've (hopefully) heard this before, but unless you're dealing with native libraries, direct hardware, or extremely high performance systems there's normally no point using pointers in C#. They're not meant to be used like they are in C/C++.

In my VoiceParticipant script I have for Vivox (Version 16), I have a void that handles participants being added in order to add a participant tap to them. However, I don't currently know how to go about parenting the tap to it's corresponding player, since the function is only called on the local player's VoiceParticipant script and I don't know how to get another game object from just a participant.

[abstract folio]

I see you calling SetParent in that code.. what is it your not clear on?

[thin jackal]

Using Microsoft Speech SDK, when i stop playing i get an error: "Cannot dispose a recognizer while async recognition is running. Await async recognitions to avoid unexpected disposals." Problem is that the natural place to do this disposal is in OnDestroy ? making my Dispose function async won`t be ideal if in OnDestroy?, so kinda lost on this one.

[grave raft]

how to get final velocity of a projectile after penetrating an armor plate?

[abstract folio]

this is not built in to unity... are you just looking for suggestions on formula? if so, what kinda parameters do you have?

[grave raft]

i have, plate thickness, impact angle, bullet mass, bullet velocity, and demarre formula

[abstract folio]

cool! not sure what that formula is.. looking it up now

[grave raft]

about more realistic projectile penetration

[abstract folio]

this one?

[tiny pewter]

this is super hard

[grave raft]

what?

[abstract folio]

this is what I found searching for that formula... does it match what yo are expeting?

[grave raft]

that isnt demarre

[abstract folio]

ok, please give the formula you are trying to implement

demarre

[grave raft]

idk the formula, i need a formula for final velocity of an projectile that penetrated the armor

[tiny pewter]

but you have it

[abstract folio]

I'm confused, if you dont know the formula what akes you say the one I posted isn't correct?

[grave raft]

im not searching for demarre formula

im searching for a formula for final projectile velocity after penetration

[abstract folio]

ah, ok happy to suggest something to get you started, but no idea how accurate iot would be.. Final V = ( ( (bullet mass * bullet velocity)/(plate Thickness^2) ) * impact angle/90 )/ bullet mass

[tiny pewter]

if impact angle=0 then v=0?

[abstract folio]

^ was trying to show it would NOT penetrate at angle 0, it would "ricochet".. but your right.. not an ideal expression.

@tiny pewter

[grave raft]

doesnt work

top values are velocities
left ones are angles
bullet weight doesnt even affect the equation

[tiny pewter]

https://www.ansys.com/

for such kind of physics and material simulation

[abstract folio]

what are values in the table?

[grave raft]

final velocity of an projectile

[abstract folio]

I dont get it.. looks like they are higher than the initial velocities.

[grave raft]

i will just substract the "final velocity" with ongoing velocity, but idk why projectile mass doesnt get afected

[abstract folio]

are the initial(top row) and final velocity(entries) in different unit's perhaps? It definatly should NOT be going faster after impact.

[modest lintel]

Hi glurthy 👋

[abstract folio]

❤️

[tiny pewter]

i believe manufacturers tested penetration depth (not speed) of different amours under different shells/distances/angles/weather but ofc impossible to get such tables online and offline
you can refer to other games to see how they calculate it

[abstract folio]

ah, and that formula I found/posted before was indeed penetration depth.. (failed to read the page properly before)

I'm using the jobs/native collections and am getting the following warning whenever my collections are left untouched for a few frames.

Internal: JobTempAlloc has allocations that are more than the maximum lifespan of 4 frames old - this is not allowed and likely a leak

However all of my native data is allocated from OnEnable with the persistent allocator, and disposed in OnDisable so I don't know why I'm getting this warning. Any ideas? Here's the main script, but I can share more if needed https://hatebin.com/vgcygaucjd

[modest badge]

Hey does anyone have experience with Facepunch library for using Steamworks API in C#/unity?

I am running into a wall bc apparently I can't access static class in another member function...

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

public class Facepunch : MonoBehaviour
{
    public static Facepunch Instance;

    // Start is called before the first frame update
    void Awake()
    {
        // start of new code
        if (Instance != null)
        {
            Destroy(gameObject);
            return;
        }
        // end of new code

        Instance = this;
        DontDestroyOnLoad(gameObject);

        try
        {
            Steamworks.SteamClient.Init( 2687800 );
            Debug.Log("steamworks initialized");
        }
        catch ( System.Exception e )
        {
            // Something went wrong - it's one of these:
            //
            //     Steam is closed?
            //     Can't find steam_api dll?
            //     Don't have permission to play app?
            //
        }
    }

    // Update is called once per frame
    void Update()
    {
        Steamworks.SteamClient.RunCallbacks();
    }

    void OnApplicationQuit() {
        Steamworks.SteamClient.Shutdown();
    }

    public void TriggerAchievement(string achievementId)
    {
        if(SteamClient != null)
        {
            SteamClient.Achievements.Trigger(achievementId);
            SteamClient.Stats.StoreStats();
        }
    }
}

The last method TriggerAchievement is what causes error when trying to reference SteamClient

Assets\Facepunch.cs(51,12): error CS0103: The name 'SteamClient' does not exist in the current context

However, it is a static class so shouldn't I be able to reference it anywhere?

[subtle river]

If it is a static class, it always exists and can't be checked for null

[modest badge]

true, I think the issue is that I was looking at code examples from older libraries in Facepunch, with similar class names. oops

there was apparently one called Client before but its not there in the source files now that i look

SteamClient.Achievements doesnt exist at all anymore apparently

so that's fun

I'm honestly baffled that Valve/Steam doesnt have a native .NET library for integrating their API into Unity... and that these 3rd party wrappers have such little support :/

like isn't this something that hundreds of thousands of devs do each year for their games?

[fresh salmon]

Hover over the error and click the light bulb icon that appears. You might just be missing a using directive.

[modest badge]

good idea, but sadly the library doesnt appear to exist in the example i was looking at anymore 😦

https://github.com/Facepunch/Facepunch.Steamworks/blob/master/Facepunch.Steamworks/SteamClient.cs

[fresh salmon]

It's a feature integrated in your code editor

You do not need access to docs to figure out which namespace it's declared in, VS can resolve that for you

Clicking the light bulb icon will show a list of actions, with hopefully one that prompts you to add a using directive

[warm charm]

Hi guys, sorry for being annoying, does anyone know how I can fit these dungeon rooms into just one square?

like this

[modest badge]

nothing

[fresh salmon]

Your code editor doesn't seem configured at all, errors should be underlined red

!vscode

[thorn flint]

Visual Studio Code guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

https://on.unity.com/vscode

[fresh salmon]

Follow the guide above and come back when it's working properly

[modest badge]

Lol. I get red underlines. My VSCode works fine

thanks anyway, i'll solve it on my own

[fresh salmon]

What? The snippet you showed would error on its own

[thin mesa]

except line 52 should be a compile error so you clearly aren't

[modest badge]

if i mess up any other code in any other file, this happens

so yea, my vscode isnt broken

its a symbolic link between unity and vscode maybe

[fresh salmon]

Well it hasn't loaded for your file

Restart it, because the error you get in the console clearlypoints to line 52, which doesn't have one underline

[modest badge]

I just followed the instructions on the Facepunch page, to include the .dlls into my Assets folder

but maybe that's the issue

[thin mesa]

it's not. it makes no sense to compare a type to null like that. and you even had the github page for that type up and should have clearly seen how you are supposed to check whether it is valid or not

[fresh salmon]

That's purely a VSC issue, as Unity reports the error correctly

[modest badge]

As I said, I combined borrowed code from a different library. It was my mistake for copying the code, but removing that line didn't fix it either bc those libraries dont exist anymore

VSC issue?

[thin mesa]

what "libraries" do not exist? because from what i see line 52 should be the only issue. i use FacepunchSteamworks and have no issues with it

well aside from the one issue i posted in the github

[modest badge]

do you have a code example of how you set achievements?

that would be a huge help to me

[fresh salmon]

It's just a missing using directive at the top

[modest badge]

so you want me to put using Facepunch.Steamworks at the top?

[fresh salmon]

I want you to restart VSC so it loads the analyzer properly for the file, then use the Quick Actions lightbulb to solve it

[modest badge]

I think there is a problem with the analyzer, I should look into that

I tried restarting and I'm not seeing it checking my project anymore (it used to)

[thin mesa]

regenerate project files

[fresh salmon]

(In fact you already use SteamClient in the same file, but it doesn't error because you fully qualify the name by putting the namespace before - is this really an advanced code issue?)

[modest badge]

thanks I forgot where to go to do that, it had reset my external tools for some reason in Unity

Ok fixed that

the analyzer works now in VSCode again

[thin mesa]

as for how to trigger an achievement, the SteamUserStats class has a list containing all Achievements. there is no Achievements.Trigger method that takes a string

[modest badge]

so now, it does have the red line, but as I said the Achievements do not exist in that library

[modest badge]

right

it was in an old library

ok so we're on the same page, I'll try using SteamUserStats

[thin mesa]

why are you blaming "old libraries" on this when this is a matter of you not reading the documentation

[modest badge]

this documentation? https://wiki.facepunch.com/steamworks/Achievement_Unlocked

[thin mesa]

point to the line where is shows an Achievements.Trigger(string) method

[fresh salmon]

haha I also saw the subtle "thanks for not helping" message directed to me that was deleted seconds later. bad faith much

[modest badge]

sorry honestly i'm just very frustrated with the documentation on their page

and this simple task has been taking way too long

[fresh salmon]

I guess the page you linked tells you how to run code whenever an achievement is unlocked, not how to trigger one

[thin mesa]

you have two options for getting an Achievement object, you can construct one by passing the name to the ctor (which, yes, is not listed on the actual docmentation page but intellisense and github both show that), or there's the list of all Achievements in the SteamUserStats class which is documented
https://wiki.facepunch.com/steamworks/SteamUserStats.Achievements
https://wiki.facepunch.com/steamworks/Data.Achievement

[modest badge]

thanks. I lost my mind for a bit there. I'm sorry for being beligerant with both of you. I'll take a break and recompose myself. appreciate your help

[heavy saddle]

This is my first time packaging anything. I'm trying to package an SDK I made and get it ready for distribution through personally hosted scoped registry. I have managed to host it using verdaccio and am able to download the package.
The issue I'm facing is when I'm done importing package to my new unity project; if i try to drag in a Prefab from the package, it seems to not hold any script references it had in the original project. When I try to manually drag in a script from the package on the prefab, it gives me this error

I have a feeling I havent constructed this package the right way... probably need to make a .asmdef file for the package?
But I've done that too and when I import the package to unity, it doesnt seem to have the .asmdef file in it for whatever reason. If i download the package as tar.gz from the repository, I can see it still has the .asmdef file in it. So for some reason it looks like Unity doesnt add that when importing package? Could be because I didnt make the .asmdef file the right way.

[thin mesa]

your packages should typically include an asmdef. but you need to make sure you are including meta files

[heavy saddle]

ok so this is my asmdef but unity doesnt add it along with the package ```asmdef
{
"name": "ArcanaSDK",
"rootNamespace": "ArcanaSDK",
"references": [
"VoltstroStudios.UnityWebBrowser"
],
"includePlatforms": [],
"excludePlatforms": [],
"allowUnsafeCode": false,
"overrideReferences": false,
"precompiledReferences": [],
"autoReferenced": true,
"defineConstraints": [],
"versionDefines": [],
"noEngineReferences": false
}

[thin mesa]

are you including meta files

[heavy saddle]

here's the package imported on unity, and here's the package once downloaded manually on file explorer

ya it has meta files

do you happen to know what an AssemblyInfo.cs file is for?
I was trying to copy how this other package is packaged and it had an AssemblyInfo.cs
dont know if its necessary or not

this is what it looks like

[upbeat path]

AssemblyInfo.cs is what is used by the C# compiler when making a .dll. Most of the information ends up in the properties of the dll and in Reflection. I would say you don't need it however the last 3 lines show that internal classes are being exposed to other dll's and this could be important

[heavy saddle]

This AssemblyInfo.cs is for another package from someone else
I was just looking at the structure to see how i would package my SDK

my sdk does utilize this package but i dont think that needs AssemblyInfo.cs

Also please do let me know if there's more info i could provide on this problem 😄

[upbeat path]

why not just build a dll and have done with it?

[heavy saddle]

hmm but I do have some prefabs inside this package that have preconfigured "examples" to use the sdk

not sure i could have prefabs in my package if the package was just a dll

[upbeat path]

the package is not a dll, the code could be

seems like you are lacking a lot of knowledge to be doing this stuff

[heavy saddle]

i am 😄

[modest badge]

Ok I'm back so I'm confused by this section of code in their example:

public void CreateAchievement() {
        Steamworks.SteamUserStats.OnAchievementProgress += AchievementChanged;
    }

How would I signal which achievement is being added by this call? I haven't seen calls like this before, and the AchievementChanged method appears to take in an achievement as it's parameter

[sage radish]

I think this warning is given if any job takes longer than 4 frames and isn't related to the NativeArrays passed to it or what allocation they use.
https://forum.unity.com/threads/jobs-lags-jobtempalloc-has-allocations-that-are-more-than-4-frames-old.513124/#post-3366232

[upbeat path]

that is not a call it is subscribing to a delegate or event

[subtle river]

Hmm. Good to know, thanks. Though all my jobs are started in Update and completed in LateUpdate so that shouldn't be happening 🤔

[modest badge]

In the documentation it says this should be the code for that event:

    public void AchievementChanged( Steamworks.Data.Achievement ach, int currentProgress, int progress )
    {
        if ( ach.State )
        {
            Debug.Log( $"{ach.Name} WAS UNLOCKED!" );   
        }
    }

I'm unclear on how this would do anything?

[subtle river]

[ExecuteAlways, DefaultExecutionOrder(-1)]
public class PlexusManager : MonoBehaviour
{
    public static List<IPlexus> Instances = new();
    private JobHandle _handle;
    private void Update()
    {
        var handles = new NativeArray<JobHandle>(Instances.Count, Allocator.Temp);
        
        for (int i = 0; i < Instances.Count; i++)
        {
            var instance = Instances[i];
            if (instance == null)
                continue;
            handles[i] = instance.Schedule();
        }
        
        _handle = JobHandle.CombineDependencies(handles);
        handles.Dispose();
        
        JobHandle.ScheduleBatchedJobs();
    }
    private void LateUpdate() => _handle.Complete();
}

[thin mesa]

like Steve said, this is subscribing to a delegate. it is also mostly irrelevant to triggering an achievement. I gave you the two ways you can get an Achievement object to then trigger it, stop ignoring that
the delegate you are seeing is a callback for when there has been progress on an achievement triggered by other code
https://wiki.facepunch.com/steamworks/SteamUserStats.OnAchievementProgress

result of a request to store the achievements for a game, or an "indicate progress" call.

[upbeat path]

that is not the code for the event. that is the code that will be executed when the event is invoked

[modest badge]

This? I clicked on that link, it doesn't explain how to trigger an Achievement...

[modest badge]

I see, ok thanks

[thin mesa]

no, but it shows how to get an Achievement object which you can then call Trigger on.
what you linked does not show how to trigger an achievement either
because, again, it is an event that is invoked when an achievement is unlocked or progress increases on an achievement.

[sage radish]

Is this happening in edit mode, playmode, or both? The [ExecuteAlways] feels like a prime suspect to me.

[upbeat path]

Without wishing to appear rude, I think you really need to go and learn some c# concepts in order to be able to understand this stuff

[subtle river]

Indeed, it hasn't been happening in play-mode so your suspicion is warranted

I am almost positive I never ran into this developing Deform, which runs in edit mode as well. I wonder what's different this time 🤔

Looks like in Deform I did not have a manager batching all of the jobs in edit-mode and let individual components update themselves immediately. I don't remember why 😅, but that's the only difference I can think of.

// Deformable.cs
#if UNITY_EDITOR
protected void Update()
{
  if (!Application.isPlaying)
  {
    PreSchedule();
    Schedule().Complete();
    ApplyData();
  }
}
#endif

For the plexus effect the manager batches all the instances' jobs in edit-mode and play-mode.

[sage radish]

Can you see if the warnings go away if you move the _handle.Complete() to the end of the Update? That breaks the async processing, but at least lets you confirm whether the LateUpdate is the problem.

[subtle river]

Surprisingly, it still happens!

It always happens after I deselect the game-object with the plexus component and particle system which seems important?

edit: I also tried commenting out the manager and scheduling/completing immediately from with the plexus update method. no luck still

[modest badge]

Ok so if I want to get the Achievements, I could do

   var achievement = (Steamworks.Data.Achievement)Steamworks.SteamUserStats.Achievements.Where(a => a.Identifier == "ACH_TEST").ToList()[0];
  achievement.Trigger();

?

[thin mesa]

instead of using Where and then ToList, just use First
or just create the Achievement object by calling its constructor

[modest badge]

what is your preferred method for dealing with the Editor keeping your game in "Play" mode on your Steam client when working on your game? do you have an Editor flag you set or something?

[thin mesa]

i just ignore it because it means almost nothing 🤷‍♂️

[subtle river]

Alright I'm pretty sure it's a Unity issue. I enabled this diagnostic setting and I don't entirely know what I'm looking at, but it seems it seems to be related to the particle system geometry. I removed my plexus component which was on the same game-object as a particle system, and I'm still seeing the leak warnings when deselecting the game-object

[modest badge]

hmm its causing an error to show in my Editor that forces me to restart intermittently

[thin mesa]

that shouldn't be causing any errors in the editor. whatever error you are seeing is likely unrelated.

[modest badge]

ah ok weird...

also, probably doing this wrong but this is my code in Awake()

Steamworks.SteamClient.Init( 2687800 );
Steamworks.SteamUserStats.RequestCurrentStats();

It's not erroring, but the results are empty when I check the Achievements?

[sage radish]

Hmm. Maybe it doesn't like having GetParticles called when it isn't actively simulating? Though, then I would expect issues before you select it as well.

[subtle river]

I thought the same thing and tried removing that call, but still get the warnings.

However I'm not getting the warnings in a blank scene with a default particle system, so could still be something on my end *sigh*

[thin mesa]

doesn't sound like an issue with your code then

[subtle river]

uuuh okay im not getting the warnings after returning to the original scene either. jeez. i have noticed the particle system editor starts to eats shit over time. like way more than the usual perf his it adds. might be related.

[subtle river]

gonna move on for now. thanks for helping troubleshoot/sanity-check

[modest badge]

Hmm well it worked creating the new Achievement from constr with your suggestion, guess I'll just go with that method! Man thanks so much for your patience.

TBH I had an edible last night, and skipped breakfast & coffee this morning... my mind was in a complete haze. Bad news. Thanks again

[silk inlet]

Vivox Participant Tap thing

[modest badge]

Hey one more question when you get a chance. I've got a solution that works, but I want to not Trigger after the Achievement has already been reached. Is this concern really a non-issue because we would need to poll the achievement status anyway? Or is there a more efficient way of doing my conditional?

Mainly jwing if there is any danger to Triggering achievements that have already been triggered again, over and over?

else if(type == "Hammer") {
    Steamworks.SteamUserStats.AddStat( "HAMMER_DAMAGE", damage );
    Steamworks.SteamUserStats.StoreStats();

    var hammerDmg = Steamworks.SteamUserStats.GetStatInt( "HAMMER_DAMAGE" );
    if(hammerDmg >= 200 && hammerDmg < 500) {
        Facepunch.Instance.TriggerAchievement("ACH_HAMMER_NOVICE");
    }
    else if(hammerDmg >= 500 && hammerDmg < 1000) {
        Facepunch.Instance.TriggerAchievement("ACH_HAMMER_TRAINED");
    }
    else if(hammerDmg >= 1000) {
        Facepunch.Instance.TriggerAchievement("ACH_HAMMER_EXPERT");
    }

}

[hearty pelican]

Looking for someone who knows how to convert what is 'seen' on screen to an image/sprite. I will need to engeneer a tool to acomplich this task. need help figuring out the right approach.

for example:
imagine in 2d a sprite of a white square and a yellow triangle overlapping slightly. then a zigzag line is created with line renderer over the two shapes. Now, screen capture this design and convert to sprite multiple.

ask your questions.. i know you may be confused lol

[sly grove]

Render the scene with a camera to a render texture

It's a pretty common task

[hearty pelican]

hmm. will that allow me to chop up the render texture into smaller pieces, like a jigsaw puzzle?

[brisk pasture]

https://docs.unity3d.com/ScriptReference/Camera.Render.html
example in here shows how to render 1 frame to a RT

cutting it up, i would do by creating sprites out of the texture with masks

also once you have the render texture with the frame on it, you can just create regular Texture2D and copy ranges of pixels to them

[sly grove]

Sure why not, it's a texture like any other. You can make sprites from it

The slicing part is a totally separate step from actually creating the texture

If you want jigsaw pieces using Masks would be the simplest way yes.

[brisk pasture]

if i had to think i would have a grid a sprite i make with it that all overlap a tiny bit

then have a jigsaw like mask for each sprite

[hearty pelican]

when you confirm my questions i have more to ask lol

there has to be a more effecient way than to have each minor piece mask their own image... is there a way to mask multiple objects then have them all retain there pizel data while moving seperatly without having each piece have a copy of the image?

[brisk pasture]

they dont

Sprite is not its own texture

[hearty pelican]

wait wait.. hear me first

[brisk pasture]

Sprite is a rect on a existing texture

and you can have many sprite reference pixels from 1 texture

[sly grove]

That's how sprites work. The pieces don't have "copies" of the image, they all reference the same texture data

[hearty pelican]

i want to be able to dynamically change the reference image (solution image) with line renderers and shapes.. so i understand how to make sprites mask to a basic jigsaw puzzle. i need this to be automated on a frame by frame situation

[sly grove]

Yeah... We're telling you how to do exactly that

[brisk pasture]

would take a bit of messing about to get it polished

but this would be a very easy thing to automate

[hearty pelican]

oh your saying i sould make a sprite and create multiple sprites from that main one?

[sly grove]

No you'd make a texture and create multiple sprites from it

[brisk pasture]

you can make the multiple sprites from a texture

its like you already got the picture for the puzzle and the sprites are cutting the pieaces out of it

[hearty pelican]

ok but i'm not seeing how i can dynamically update all the sprites to render new textures by frame

[sly grove]

The masking bit btw would be separate from the sprite slicing. Sprite is always a rect. To get jigsaw shapes that would be another texture that has jigsaw shapes that you'd be masking the sprites with

[sly grove]

Just... Write the code to do it

You'd make the sprites in code

With Sprite.Create

[hearty pelican]

ok so its reasonable to create sprites and rewrite them every frame by using a render texture?

[sly grove]

Why every frame?

[brisk pasture]

also you could you could even have them of a video

[hearty pelican]

because it is needed for a mechanic

[sly grove]

You can render to the texture every frame no problem and leave the sprites alone, that would work fine

[brisk pasture]

they are not coppies of the texture

they are referencing it

its literally a rect and a pointer to the texture

so if you modify the texture in place

[sly grove]

Like if you want a video jigsaw puzzle that's easy enough with a render texture

[brisk pasture]

the sprites will update as well

[lament salmon]

Lol, is that an original idea?

You might be onto something

[sly grove]

I mean from this conversation yeah

Kind of interesting actually

Unlocking lots of game possibilities in my head lol

[hearty pelican]

ok so yes this is essencialy what i want to do, but i need each jigsaw piece to understand its pixel composition.

[sly grove]

Wdym by understand

You need to do some analysis on the pixels? That can be done programmatically easily enough too

Actually accessing the pixels is straightforward. Dunno what you want to do with them though

[hearty pelican]

so i'll just share my idea.. so you understand a bit better.

imagine a 10x10 grid of squares. these are the jigs.
the solution image would look like an abstract shape collage.
once one of the shapes (in the main solution) is completed in the collage, the shape will shrink till it disappears, leaving the jigs to determine how they should update.

this is a very basic pitch

so the puzzle becomes "less chaotic" as you solve, leaving the player feeling some dopamine for small task completion.

imagine it like this
a puzzle of a farm with a variety of animals,
correctly placing all the "horse" pieces makes the horse disapear from the main solution, and the player 'collects' the horse as an acheivement for example.

so i need some way for the jigs to know where they belong on the main grid, as well as, the small group they belong to within the grid.

[wraith storm]

Hi, I'm not sure what this is called so I've not been able to simply google it, but does c# in Unity have that programming syntax where you only call a method on an object if that object is not null?

So instead of
if( myObj != null ) { myObj.MyMethod(); }

You can do something like
myObj ? .MyMethod()

[brisk pasture]

it depends on what myObj is

if its a regular C# object sure that will work

if its somethign like a MonoBehaviour it will cause your pain later due to how unity fakes null on things

[stuck plinth]

it's called a "null conditional operator" if that helps in future!

[past silo]

I have been stuck with this issue for a couple of hours now, and im almost bald. In my scene, i have six different gameobjects with a simple ObjectiveOnGameObject-script that lets me choose an Objective and a RoomHandler (A simple cube that i want to change color on).

The problem i got is, the ObjectiveManager can choose randomobjectives for me, and the roomhandlers connected to my gameobjects via the ObjectiveOnGameObject are changing colors to red, just as i like them to. But when the player interacts with one of the gameobjects, do use the ObjectiveManagers CompleteObjective-method, the last "used" roomhandler is the one getting a color-change to black, and not the correct one.

I have quadupplechecked so each of the six gameobjects in the pictures, have the corresponding roomhandler set in the script. The room handler is supposed to represent the room and if there is an active objective in that room so the player easily can see where there is an objective :).
See the picture below and the script aswell. What am i doing wrong?

https://gist.github.com/Lillbirro/8a2e22d06b9d4b61d7e9b5295fb29e93

[stuck plinth]

there's a lot of game logic to try and understand here based on that description, but giving this a quick read i see you're modifying which objective an object points to on line 91/118, is that intended? you search by objective reference for the one to turn black, and that's the only place i can see you changing those objectives at runtime, so if they don't match what you expect in editor, i'd start there

[past silo]

Well, i think that they are similar since one is being used if the tag != null, and the other if its null, in the ChooseRandomObjective(string tag = null).

[misty glade]

I agree with Simon - this is a lot of code to try to digest, and you can (should) improve a lot of the readability here: like firstly, your ChooseRandomObjective() has this huge if/else statement where most of the code within appears the same? if you're copying and pasting code you're doing something wrong - just do the part that's different within the if/else. I'd also probably read up on programming calesthenics and try to early-out in your if statements instead of wrapping all the meat in an if statement - ie:

if (something == null) return;

// vs

if (something != null)
{
   // a bunch of code
}

I'd also avoid doing the foreach (var pair in activeObjects) use of 'var' because activeObjects isn't defined near the foreach loop, so it requires someone (me/you/whomever) to hold that trivia in their brain (and scroll up/down in the file to try to figure out what it is).

Don't embed classes like this unless it's an internal class (which it isn't, it's public). I get what you're trying to do but it's kind of obscuring the problem. I do like this class, but it should be in it's own file, and should probably have more data in it to identify it - like an ID. I'd also name these fields/properties properly - PascalCase and not camelCase so that lines like #99 are easier to debug and verify you're doing what you think you are. It should be activeObjectives.Add(new ObjectiveRoomPair { Objective = selectedObjective.objective, RoomHandler = roomHandler });

I'd probably also move away from your use of == for game object comparison since unity objects have overloaded operator== and it doesn't always work like you might expect (an object can exist but be destroyed and UnityEngineObject.CompareBaseObjects will return "true" for nullness. Most of the time it's the same thing, but not always.

That being all said - the code looks fine from what I can understand, but you're likely going sideways by not passing in the correct Objective in CompleteObjective, OR you've linked the wrong objective accidentally to the room handler.. This script doesn't show how your objective with tag's .roomHandler property is set.

I'd start debugging this by adding some IDs to your gameobjects, displaying the ID in-game (either via the game object .name or draw some floating text on the object itself) and either adding debug.logs to all your methods (especially CompleteObjective but also ChooseRandomObjective ) to make sure the right room is being stapled to the right objective and then go from there.

GL!

[past silo]

Cheers for your input, yeah this script in particullar is a huge mess, cause i think i tried to do to many things at the same time, henche the huge chunk of meat in the ChooseRandomObjective.

Ill take a step back, and see if i can approach this another way. Thanks alot for the input!

[misty glade]

All good... Yeah, I mean, I've looked at this code for the last 15 minutes and no obvious bugs pop out to me, but .. it's written in a way that's a little hard to read.. but I mean, I think it's sound

I'd just make sure that when you add your items to the dict of lists that you're adding what you think you're supposed to be - if rooms have an id and objectives have an id, then you could just toss a line like this into the mix and you'll quickly see if you have a bug:

           // Add the ObjectiveRoomPair to activeObjectives
            activeObjectives.Add(new ObjectiveRoomPair { objective = selectedObjective.objective, roomHandler = roomHandler });

          Debug.Log($"Added a new objective to {tag}: ObjId: {selectedObjective.Id}, RoomId: {roomHandler.Id}");

And then when you complete the objective, same deal - spit out the id of the objective, tag, and room, and make sure everything is sane

but your problem likely isn't in this script

I found another bug, perhaps

in your else statement in ChooseRandomObjective() you don't seem to be adding it to the list of active objectives

which again, is why you shouldn't copy and paste code 🙂 .. lemme refactor it for you

[misty glade]

I think it should look more like this: https://pastebin.com/1FBBymJP

actually hang on

https://pastebin.com/mSNrn8DA

Anyway, you get the idea - trim all the copied and pasted code so you aren't missing something that only happens in one of your if/else blocks (unless you intend to)

[radiant wave]

I'm working on a VR game with non-euclidean architecture. For that system to work, we've created a system with different layers per room. It works great! But now I have the following issue: The scientist in this screenshot needs to be able to spot the player. In all the other levels I'm using raycasts for this, but the scientists are behind a glass window. The window will cause the raycast to be blocked. I can't set the window to Ignore Raycast Layer though, because it wont get rendered then in my current room setup. (In fact I cant change it to any other layer). Any idea on how I can solve this? It's only the windows that should be ignored.

[sly grove]

A fun little hack is to change the layer, do the Raycast, then change it back

[radiant wave]

Including references from the scientist to all the windows he might look through? That will be messy 😩😄

[cursive horizon]

do the windows need to have colliders at all, or could they just be visual?

[junior stone]

So, I ran into a bug and reported it and it was confirmed for the Unity SRP in 2023 versions and later (it cant blit quads)

My org is kinda breathing down my neck about it because it all works in studio but doesnt work in published games - is there something I can do here?

[untold moth]

Make them get the enterprise license and fix the bug yourself.🤷‍♂️
Or make your higher ups contact unity and negotiate a patch or something.

Or find a walk-around.

[junior stone]

Yeah I jiggled stuff for a week to get a workaround, I dont think im capable of finding one

renderdoc just said "its not emitting quad geometry here" so I was like 🤷‍♂️

[untold moth]

Can't help you any more than what I said without knowing the details of the issue.🤷‍♂️

[spiral swift]

btw, how would I be able to do a cutscene using instantiated objects?

[livid kraken]

Use https://docs.unity3d.com/ScriptReference/Physics.RaycastAll.html and sort the list to find the player

Better yet use the non alloc version https://docs.unity3d.com/ScriptReference/Physics.RaycastNonAlloc.html

[livid kraken]

I dont understand the question

[regal olive]

Yo

Can I get some help

[untold moth]

If that's the right channel for your question.

[regal olive]

I need help with my procedural world generation

It won’t take my code and there is no errors

[untold moth]

I see you decided to ignore the suggestion of asking in #archived-code-general 😅

[regal olive]

Wym?

I was told to come here

[untold moth]

You were linked to the #archived-code-general channel, and you came here.

Ah I see. They also linked this channel too.

[regal olive]

I was linked to all the code channels but I just clicked this one

[untold moth]

Anyways, what doesn't work?

[regal olive]

My procedural world generation

It won’t take my code

[untold moth]

Does the code run?

[regal olive]

Yes

[untold moth]

wdym by "won't take my code"?

[tall ferry]

Look at the #854851968446365696 on how to ask. It shouldnt be troubling to find out what your issue is

[regal olive]

Tbh idk just won’t run my code In unity

[untold moth]

Does it run your code anywhere else?

And how do you confirm that it doesn't run your code?

[regal olive]

Yes I ran the game and it did not take and do anything

[tiny pewter]

then your code doesnt run, have you debug it first

[regal olive]

Yes

[tall ferry]

I have doubts this is gonna be a code advanced question. Definitely gonna be a more "this isnt my code and idk how to run it"

[regal olive]

Sorry about the way I worded things never good at questions

[untold moth]

That doesn't answer my question. You say that it doesn't run your code in unity. That implies that "something" runs the code somewhere else?

[regal olive]

No it’s my code

[regal olive]

Yes in vs it ran with no errors

[untold moth]

Then give short summary of what it does and where it is run from?

[regal olive]

So I’m a little lost

[untold moth]

You "ran it" in vs?

[regal olive]

Yes

[untold moth]

How?

[regal olive]

It ran with no errors

[untold moth]

How did you run it in VS?

[regal olive]

Testing for errors do it with all my codes

Big like it displayed anything just ran it to see if it displayed any errors or not

[untold moth]

How did you test for errors?

[regal olive]

Ok now you’re confusing me

[untold moth]

How did you run it in VS?

[regal olive]

I clicked the start button

[untold moth]

To run a code you need to compile/build it and execute the program. Is that what you did in VS?

[untold moth]

In VS?

[regal olive]

Yes

In vs

[untold moth]

It's unity project, right?

[regal olive]

Yes

[tall ferry]

Do you know how to run any code in unity..?

[untold moth]

This?

[tall ferry]

Like hello world

[regal olive]

Yes

[untold moth]

it doesn't run the code

[regal olive]

Yes

[tiny pewter]

it is just attach a debugger not playing

[untold moth]

It attaches the debugger

So to summarize: you didn't run the code anywhere. And you don't have a confirmation of wether the code runs or not?

[regal olive]

They don’t appear they’re just gray for me

That’s what I mean it won’t work

[untold moth]

What "they"?

[regal olive]

White and red green blue yellow

[untold moth]

Please use screenshots. It's supper annoying to try and understand anything from a photo of a screen

[untold moth]

These look like read only or non serializable fields. What do you expect to happen with them?

[regal olive]

Ok wait it says waves is missing the class attribute extension of native class

[regal olive]

This is my first time coding something like this so it’s not perfect but it works still working on it

[untold moth]

We can't help you unless you start sharing details of the issue properly. Like code and screenshots of the errors.
Check #854851968446365696 on how to ask questions properly

[regal olive]

I’ll figure it out tomorrow it’s fine Ty tho

[tall ferry]

Maybe try a hello world first as well so you can see how to actually run code in unity

[regal olive]

I know how to run code in unity

It’s not rocket science

[tall ferry]

It should be extremely trivial for you to see why your code isnt running then. Since you also said you debugged it above

[regal olive]

Yeah I’m watching one now

It’s probably something really simple I just overlooked

[untold moth]

Watching what? A debugger?😅

[small gull]

reimport ur script

[regal olive]

Ok

Yeah that worked

[regal olive]

Presh🙏

[small gull]

have you changed ur script's name?

[regal olive]

Yes

When I first added it

Should have waited tbh

[wraith storm]

THanks for your reply yesterday, i only just saw it. So it sounds like I shouldn't use the 'null conditional operator' then , because it will cause problems with MonoBehaviour grabage collection or object lifecycle?

[stiff hornet]

you can make an extension to make it work correctly if you want to use that syntax

using UnityEngine;

public static class UnityExtensions
{
    public static T OrNull<T>(this T unityObject) where T : Object
    {
        return unityObject == null ? null : unityObject;
    }
}

Then use it like:

if (unityObjectThing.OrNull()?.Func())

[stiff hornet]

And you can't just use ? directly as that doesnt query the C++ side to see if the unity object still exists.

when you check with == that operator has been overridden for the Unity Object base type, so it correctly asks the C++ side:

? cannot be overridden, but the above work around does the correct check which then allows you to use ?

[spiral swift]

Like, my RPG party's charcaters are DDOL objects. How could I make a cutscene involving them, since you can't move them around with the timeline

[humble leaf]

1. Create a different object using those sprites, and hand animate them in timeline.

2. Create a robust system in timeline that will let you move the actual characters through waypoints to move or to call specific animations.

3. Do #2 without timeline and do the entire cutscene in code inside of a coroutine so you can yield to things like waiting for characters to reach a point, or for a dialogue popup to complete before proceeding to the next moment in the cutscene.

[brisk pasture]

Perfectly safe for non unity objects. But yeah for unity objects you need to do a null check using the equality operator

[subtle river]

Anyone know if there's a faster way to get the current color/size of shuriken particles
I can't find any way to get the data besides iterating over every particle on the main thread.
Would love to at least be able to get them all in one batch. I'm open to doing weird stuff if necessary.

// So frustrating to have to do this, but we can only access each particles current color and size
// one at a time on the main thread
for (int i = 0; i < ParticleSystem.particleCount; i++)
{
    _particleCurrentColors[i] = particles[i].GetCurrentColor(ParticleSystem);
    _particleCurrentSizes[i] = particles[i].GetCurrentSize(ParticleSystem);
}

I'm doing this for a plexus effect and everything is nicely jobified except for getting the particle sizes/colors.

[sage radish]

Do particle system jobs not help here?
https://docs.unity3d.com/ScriptReference/ParticleSystemJobs.ParticleSystemJobData.html

Looks like you can get current sizes, but only start colors for some reason. But if you use a custom attribute instead of color, you can get that in the job.

Or if you can make assumptions about how the color changes, like if you know the Color over Lifetime module is being used, you can get the gradient from that ahead of time and use the particle age to get the current color.

[subtle river]

That does look like the best way, thanks!

[hardy jacinth]

Am I crazy or is ShaderUtil.GetShaderMessages not working at all? I have a Shader asset and it displays errors on inspector, but this function and ShaderUtil.GetShaderMessageCount returns zero

How to query shader errors and warnings that are normally displayed in shader editor?

[sage radish]

According to this, the shader inspector uses that method to get the errors and warnings.
https://github.com/Unity-Technologies/UnityCsReference/blob/1b4b79be1f4bedfe18965946323fd565702597ac/Editor/Mono/Inspector/ShaderInspector.cs#L371

[hardy jacinth]

hmm, seems like the ShaderUtil.FetchCachedMessages(shader) inside OnEnable in the source you linked is essential, but it has internal scope... I called it in a debugger and indeed the message count and messages are detected properly after this

[sage radish]

ShaderUtil.ShaderHasError and ShaderUtil.ShaderHasWarnings both call this internal method and are themselves public.

[hardy jacinth]

this seems like a public API bug on unity's part then

and it indeed works if I trigger one of the methods above, that trigger FetchCachedMessages indirectly

[frigid cloud]

Hi all! Hoping to find some camera experts here!

I'm trying to build my own camera view type thingie (MS Paint picture attached) here but I'm lost at both ends:
A: I don't know how to build my own unity camera view where I can actually edit or modify these parameters
and
B: I don't know what kind of parameters I'd be changing to produce my desired effect.

Anyone here have a good starting point for this sort of thing? I've tried googling around but am only getting methods of moving the camera itself and not warping its viewport.

Here's what I want to do: as the distance from the camera increases on the Z axis, I'd like the view angle to bend towards the Y axis. This will hopefully produce a "rolled world" effect similar to how Animal Crossing games look. I know there are ways of moving the actual WORLD downwards to create this desired look, but that solution requires a shader on every single object in the scene and also messes with volumetric lighting. This sort of camera thing SHOULD be possible, right? I'm totally lost, though, so please let me know if you have a good starting point for this!!!

[brisk pasture]

so this cant be done with camera projection alone, most games that do it are doing it via a vertex shader they use on all objects in the game, that offsets things as they get further away from the screen

the kinda stuff you can do with camera projection is really limited to what you can represent in a 4x4 matrix multiplication iirc

[frigid cloud]

dang, that's the one thing I wanted to avoid

it feels like it should be easier to bend the camera than it would be to move everything but the camera, you know?

is there a way to merge multiple camera projections together? like what if I do something like this, where based on the distance from the main camera, I use the projection from a different, linked camera?

[brisk pasture]

hopefully someone else knows more then me, but dont think so and not sure how you would combine that

either way where the transformation is actually take place is in the vertex shader

UnityObjectToClipPos is called in the vertex section of all shaders

its what is doing the transformation

[frigid cloud]

I'm trying to avoid having to set a shader on every single object I ever make. plus the vertex shader route messes with lighting projections.

I appreciate you stopping by either way, this was helpful even if there's no easy solution

[brisk pasture]

its taking UNITY_MATRIX_MVP and multiplying it by objectPos

[frigid cloud]

ah, so you're saying there'd be a way to interrupt the vertex displacement portion of shader processing and handle the displacement globally?

[brisk pasture]

really dont think its as big of a deal as you think to swap the shaders, the new vertex function can just be written once and included where needed

[frigid cloud]

it's a huge pain in the ass, not to grouse about it too much but it's quite frustrating as a process 😦

moreover, though, my thinking was... what's easier. move the camera or move everything else. yanno? 😛

[austere jewel]

Well, matrices cannot be bent, they can only be skewed. Composing a scene using enough cameras at different depths sounds expensive as all hell

[brisk pasture]

have done it before, you just automate it

[frigid cloud]

if it's not possible it's not possible, I totally get that

[brisk pasture]

also there is no difference between moving the camera up, and moving the geo down, all the camera projection is happening in the vertex shader to start with

its just hidden from you since its reusing the same function in all existing shaders

[humble loom]

does anyone know either some existing resources or if theres' a unity specific way to handle UI dispatch for world space UI's? specifically it's a VR Game with several world ui "frames" and trying to finalize the design on a ui dispatch so the Ui designer can iterate in parallel to UI code being written, and they can just be wired up via id registration either via enums, strings, etc whatever. our studio has tried like several iterations on a system and there's always some major drawback that needs to be addressed, and it feels like addressing one exposes another. For example, our current system is reliant on prefabs that both coders and designers have to touch, which means we have to be diligent about locking, passing prefabs back and forth, and it's just friction we don't want.

the ideal workflow would be like, the ui designer sets up the whole UI, adds the script stubs for controlling the UI, wires up the references, adds a ui dispatch component and registers it with some ID, and the whole while the programmer is working on the controllers, and hooking it into the game logic, saying something like UIDispatch.LobbyScreen.Show(myNewViewID);

and if the artist submits their work first, no biggie, if the programmer commits their work first, it will attempt to show the UI but say, fire off a warning saying "no View Registered with provided ID" which is no problemo, and when the artist commits, it'll just work

big wall of text, but having a system like this would be unbelievably helpful. just feels like very difficult to make that full experience cohesive

[frigid cloud]

Okay, I actually did a 3 camera test and I think this might work

Game View. Note the foreground higher than the background.

Scene view. Note the cubes and planes on the same axis

[humble loom]

not entirely sure what you're trying to accomplish exactly. read your previous messages. you want something like

crap. like the end scene of the matrix where neo is bending the walls?

[frigid cloud]

I want something like Animal Crossing: New Leaf, where the world appears to roll as you walk across it. Right now all of the places I look are suggesting that I write a depth-based shader that does vertex displacement, which has its own problems display-wise and doesn't actually produce the exact effect I'm looking for.

Here's another MS paint drawing. As you can see, displacement produces some weirdness that I don't want. Plus it's a huge pain in the butt to have to attach a shader to everything. And it messes with lighting.

hmmm I probably will need 1 camera per pixel to make this look smooth

so multi cam overlay approach... probably not feasible

[austere jewel]

You can do the latter in a vertex shader

There's nothing stopping you from doing any distortion you want apart from the number of vertices

[tacit harbor]

Please kindly help me, I want to find out how I can make a better save/load system. I don't know, I've tried my method. Does anyone have examples or can give me concrete advice?https://gdl.space/cetetehipi.cpp

[tiny pewter]

not sure if it is code advance or general, btw

private struct Entry {
    public int hashCode;    // Lower 31 bits of hash code, -1 if unused
    public int next;        // Index of next entry, -1 if last
    public TKey key;           // Key of entry
    public TValue value;         // Value of entry
}
```this is how dictionary stores the key and value, you can ignore the next field, it is just pointer of linked list
https://github.com/microsoft/referencesource/blob/master/mscorlib/system/collections/generic/dictionary.cs

[upbeat path]

why

        string jsonValue = JsonUtility.ToJson(value);
        if (!data.ContainsKey(key))
            data.Add(key, jsonValue);
            data[key] = jsonValue;

Also why Dictionary<string,string> instead of Dictionary<string,object> and leave all the serialization to the Save method

[fickle inlet]

how to refernece CinemachineVirtualCamera in code? I tried using Cinemachine and using UnityEngine.Cinemavhine, non is working

[upbeat path]

The Namespace is Cinemachine, if VS is not picking it up you may need to Re Gen your project files

[tacit harbor]

can you please give me an example, maybe I don't see the general concept, or I'm getting confused at the moment, I apologize

[upbeat path]

I simply wondered why, when you have a new key you add the key/value and then you update the value with the same thing

also if you use a Dictionary<string,object> there is no need to update the dictionary at all

[charred drum]

Hello, I'm trying to address something when it comes to creating maps for my game: You need to make a scene, seperately. I was thinking of making it so that when I create a ScriptableObject ScriptObject_Map, it'll automatically creates a scene asset and attaches itself to it. I know how to do that, however, there doesn't seem to be a simple solution for ScriptableObject OnCreation or so, and some people online were saying I should use Awake when creating an asset, and then switch a private variable to true and have the awake set to stop if it is true, but I am not sure if I should 100% do that

[upbeat path]

At some point you have to do a ScriptableObject.CreateInstance/AssetDataBase.Save to create the asset. There's your oncreation right there

[charred drum]

Do NOT cross post, chose the relevant channel and stick to it

[hardy jacinth]

What an interesting problem! It indeed seems hard and there could be many approaches. Doing some kind of space transformation in vertex shader that you include in other shaders seems to be the most foolproof way to bend vertices of geometry. Using some rotation around a far radius on the -y axis should do the job.

Alternatively maybe something like division not by z by z² (?) using some advanced perspective projections of homogenous coordinates. But then I bet there is no simple way for your shader to automatically perform perspective divide and you would have to do it yourself.

I am not sure if that's simply possible with matrices

It might be difficult to explain, so here is a graphic:

what you could possibly need is a space transformation, that would work as a "curved frustum"

it would be up to you to limit the portion of this "bent frustum"

for example only to the upper half

something a'la discard the red part

but.. well, this is how it would probably look like, it could make it seem to as curved but bend weirdly

personally I think that's a big gamble if that would work and if this was even a) easy b) performant c) maintainable

imo bending coordinates in vertex shader could be better

[royal zealot]

how can i implement camera collision?

how would i go about recreating this type of destruction in unity??

[livid kraken]

https://gitlab.com/dima13230/unity-libre-fracture or https://github.com/dgreenheck/OpenFracture or buy https://assetstore.unity.com/packages/tools/game-toolkits/rayfire-for-unity-148690

[olive anchor]

I’ll check these out later because it’s 2 am right now but Ty

[livid kraken]

Honestly your best bet is just to buy rayfire

Fracturing is easy, its the clustering and structural destruction that is hard

[frigid cloud]

that might work as well! I'm reading up on multi camera compositing, I think if I can get the views of foreground/midground/background to merge it'd work... but would have a "crease" instead of a bend

[hardy jacinth]

Just have in mind that multi-camera compositing could be an equivalent of x3 rendering performance penalty

[frigid cloud]

hmmm, that's a very valid concern

[frigid cloud]

Okay, further updates. I'm poking around in URP's fullscreen post-processing flow. I think I can potentially do vertex displacement as a fullscreen shader. That being said, even my test material/shader isn't applying. Is there some step I'm missing here?

[sage radish]

This is not possible purely in the camera, because you can't create a non-linear projection matrix. This is a limitation of GPUs. They can't render curved lines. They only render triangles with straight edges. So the only options are to either estimate it with vertex displacement, like Animal Crossing does, but then you need enough vertices to estimate curves, or you can bypass the triangle rasterizer entirely and render everything in the scene with something like raymarching.

[abstract folio]

I have the following function, where I grab the data computed by my compute shader.

    {
        if (output != lastCallStreamoutput || writer == null)
        {
            if (writer != null)
                writer.Close();
            writer = new BinaryWriter(output, System.Text.Encoding.UTF8, true);
            lastCallStreamoutput = output;
        }
        AsyncGPUReadbackRequest requestPos = AsyncGPUReadback.Request(particlePositionBuffer);
        AsyncGPUReadbackRequest requestTem = AsyncGPUReadback.Request(particleTemperatureBuffer);
    //    Debug.Log("Starting data request");
        yield return new WaitUntil(()=> requestPos.done && requestTem.done);
        try
        {

            posDataBytes = requestPos.GetData<byte>();
            temDataBytes = requestTem.GetData<byte>();
            //    Debug.Log("Data received. pos data:"+posDataBytes.Length+" bytes   temData:"+ temDataBytes.Length+" bytes");

            writer.Write(posDataBytes.ToArray());
            writer.Write(temDataBytes.ToArray());
        }
        catch (System.Exception e)
        {
            Debug.LogError("Exception thrown will reading GraphicsBuffer data, or writing to file: " + e.Message);
        }
    //    Debug.Log("Data written to fileStream");
    }```
The code waits until the AsyncGPUReadbackRequest’s are “done”, but still, very occasionally (I’d estimate less than 1 in 500 runs), it generates the following exception:
``Exception thrown will reading GraphicsBuffer data, or writing to file: Cannot access the data as it is not available``
Any thoughts on what might be causing this- how to avoid it?  Am I checking that the data is ready improperly?

[frigid cloud]

good info, thank you!! Any idea on why my post-processing isn't post-processing?

[fallow echo]

which line throws the exception?

[abstract folio]

not actually sure, my console shows the Debug.Log line, AFTER I caugt it, but I'd assume one of these : posDataBytes = requestPos.GetData<byte>(); temDataBytes = requestTem.GetData<byte>();

[fallow echo]

ah... well you can see the stack trace in the error message

[long ivy]

you are waiting until both are complete, but the data is only available for one frame. Unless they both always finish on the exact same frame, one of those GetData calls will fail

[abstract folio]

hmm.. it doesn't.. lemme try Debug.LogException instead.

[abstract folio]

I dont understand. The compute shader computes both those arrays as output in a single pass.

[long ivy]

Empirically it appears that's what's happening though

[abstract folio]

Agreed, but I dont see how. I wait until BOTH array are ready- or I though I did.

[long ivy]

and that's the problem

unless they finish on the EXACT same frame, you are guaranteed that one of those GetData calls will fail because the data has been lost by that point

[abstract folio]

hmmm,, if that's the case how does it EVER get pst this line: yield return new WaitUntil(()=> requestPos.done && requestTem.done);?

[long ivy]

499 out of 500 times, they finish on same frame

[abstract folio]

and when the dont.. why doesn't the && make the result false, and not let it pass?

(sorry I'm not usually this thicl)

[fallow echo]

because they are both done... one of them was just done earlier (previous frame), so data is no longer available 🙂

[long ivy]

let me repeat: when AsyncGPUReadbackRequest is complete, you have one frame to access the data. You can't wait for anything else https://docs.unity3d.com/ScriptReference/Rendering.AsyncGPUReadbackRequest.html

[abstract folio]

"so data is no longer available" but .done remains true? ok- that I was not expecting.

thanks guys I'll re-code it to grab EITHER one thats ready, and THEN wait till both are done before "finsihing".

[fallow echo]

+1 thanks from me, I didn't know it's only available for a frame 🙂

[hybrid belfry]

Hi, I'm looking for some advice on Meshes (I'm new to this 🙂 ) - I am generating two faces to fill the end of a bezier path as shown. I originally had an issue where the normal of the second face, was drawn rendering inwards towards the path. I solved it by reversing the order of the triangles, but unsure if this is a good or bad practice with meshes? Thanks

[lament salmon]

Nothing 'bad practice' about that. Triangles indices need to be in clockwise order.

Relative to the path, the start face and end face should indeed be in different orders

You are doing it correctly

[hybrid belfry]

Cheers. Although I'm not clued on the Bezier maths just yet, this appears to always work for any path I draw :). I assume unity will render counter-clockwise ordered vertices in the opposing direction? Thanks

[lament salmon]

Yes, or well, it will completely skip triangles that face away from the camera

[hybrid belfry]

I see

[manic orchid]

Google failed me, GPT is useless as always - Discord, can you help me?
I want to read values out of a depth texture of a specific camera. I'm on the builtin render pipeline btw.

So I have multiple cameras and I only care about one of them. And I want to shoot raycasts, but my obejcts can't have colliders, they only have depth.
And instead of rendering the whole scene with a custom shader again, which costs a lost, I just want to grab the depth texture and read there.
It's OK to copy values over to another texture using Graphics.Blit() or something.

This doesn't work:

using UnityEngine;

public class DepthTextureReader : MonoBehaviour
{
    public RenderTexture depthTexture;
    public Texture2D depthTexture2D;

    private void OnPostRender()
    {
        depthTexture = Shader.GetGlobalTexture("_CameraDepthTexture") as RenderTexture;

        if (depthTexture == null)
        {
            Debug.LogError("depthTexture is NULL");
            return;
        }

        int width = depthTexture.width;
        int height = depthTexture.height;
        if (depthTexture2D == null)
        {
            depthTexture2D = new Texture2D(width, height, TextureFormat.RFloat, false);
            depthTexture2D.name = "depthTexture2D";
        }
        else if (depthTexture2D.width != width || depthTexture2D.height != width)
        {
            depthTexture2D.Reinitialize(width, height);
        }

        RenderTexture.active = depthTexture;
        depthTexture2D.ReadPixels(new Rect(0, 0, width, height), 0, 0);

        // Access depth values (example: print the depth value at pixel 100,100)
        float depthValue = depthTexture2D.GetPixel(100, 100).r;
        
        Debug.Log("Depth value at (100, 100): " + depthValue);
    }
}

Does anyone know of any 3D Delaunay tetrahedralization libraries/plugins? I need to find all non-overlapping triangles/tetra between a set of 3D points. There's lots of stuff out there for 2D Delaunay triangulation, but I can't find anything for 3D

[abstract folio]

Dont know any libs for that. Getting a set of non-overlapping triangles from a random set of points could potentially lead to many solutions, at least if you ONLY have points- or do you have a mesh?

[austere jewel]

I have exploited lightprobe tetrahedralisation before I think...

[sage radish]

There's
https://docs.unity3d.com/ScriptReference/Lightmapping.Tetrahedralize.html
but editor only.

[abstract folio]

Man, soon as I get over my impostor syndrome, you guys post something like that and boom, I'm back to "you know nothing Jon Snow". What does the lightmapping stuff do with with/ why does it need, tetrahedrons? To best light the center of it?

[sage radish]

There was a GDC presentation about it. Unity has a unique solution for handling light probes by using tetrahedrons and barycentric interpolation. It's a good presentation.
https://www.gdcvault.com/play/1015312/Light-Probe-Interpolation-Using-Tetrahedral

Naive light probe solutions use uniform grids to quickly find the nearest probes and interpolate between them with trilinear interpolation. But that means you can't hand place probes in the scene with more density where it matters. Quickly finding and interpolating between the nearest probes when they are arbitrarily placed is a more complex problem. Unity solved it with tetrahedrons.

It's the reason why Unity draws these lines when you have a Renderer selected in a scene with light probes. It's visualizing the four vertices of the tetrahedron the renderer is contained in.

[subtle river]

@abstract folio Just points. As a super informal definition, I want to do something similar to 2D delaunay triangulation (see gif) in 3D, but instead of finding a 3D hull, I want to "fill" the 3D hull with tetra so I can find non-overlapping triangles and lines between the 3D set of points. It does sound like how Unity tetrahedralizes light probes for interpolation is basically what I'm looking, tho my use case likely makes piggy-backing off of that functionality difficult.

@sage radish @austere jewel Thanks for pointing me at the light-probe thingy. Unfortunately my use-case involves running this over a set of points from an arbitrary particle system, so it needs to work on a changing set of points at runtime which is probably not what Lightmapping.Tetrahedralize is meant for? For further context, I want to use this to find facets/lines connecting the points for a realtime plexus effect. I have the lines working using a nearest-neighbor search, but I also want to draw triangles connecting the points. I tried doing nearest-neighbor for this as well, but it was quite messy/erratic. I figure if I use delaunay tetrahedralization I could use the data for lines and triangles. And it would be more stable and provide flexibility in how it's rendered. Tho this may be unfeasible/beyond my ability to pull off performantly. Either way, thanks for taking a look yall 🙂

Reference: https://youtu.be/cbO4VsXUVZM?t=302

[sage radish]

Maybe you could convert a 2D Delaunay triangulation implementation to 3D. This one looks promising:
https://github.com/andywiecko/BurstTriangulator.
It'll probably be a bit more work than just Find & Replace float2 -> float3, Circle -> Sphere, but my understanding is that the underlying algorithm being used here (Bowyer–Watson) works for any dimension.

Or maybe it's just easier to implement the algorithm from scratch.

[subtle river]

Thanks for the link, I'll take a look 👍

[mellow plinth]

Does IL2CPP, optimizes typeof(T) == typeof(U) when one of both is a value type?

[fresh salmon]

typeof() returns Type which is a class. Though if those are generic type parameters, the compiler is smart enough to sometimes elide entire blocks of code where the condition cannot be true.

[mellow plinth]

In CLR, I can do for example typeof(T) == typeof(U), and the JIT is able to replace that with a constant boolean if at least one of both is a value type as the methods are specialized. But I don't know if Unity does the same

For example, if (typeof(T) == typeof(int)) is automatically propagated

Making it zero-cost

[fresh salmon]

Good question, and there's probably not much impact. Are you experiencing a performance drop on that very specific part?
No => Don't worry about it

[mellow plinth]

That depends if you are using it in a hot path

[fresh salmon]

So that would mean "no". Compilers are smart and you shouldn't worry about these. IL2CPP may not do optimizations itself, but whatever it uses after that to produce machine code would surely get rid of the unnnecessary code paths.

[severe loom]

If i am using a tilemapcollider with composite collider, is it possible to get the "composite piece" i collided with in script?

aiming to get coordinates of rectangle corners

[sage radish]

I would say it depends on which IL2CPP code generation option you are using. If you're using this option:
https://blog.unity.com/engine-platform/il2cpp-full-generic-sharing-in-unity-2022-1-beta, then value type generic instances will share the same code, so the compiler cannot optimize this sort of comparison. Whereas if you are using the other option, IL2CPP will generate a separate C++ class for each value type generic type, where the compiler might be able to spot this sort of constant expression. But that depends entirely on how IL2CPP implements the typeof expression.

You can inspect the IL2CPP code that is generated in the debug folder that is generated with your build.

[timber flame]

I want to be able to set the depth buffer based on my 2d sprites to order them correctly. Can you help?
Should I use SRP and write custom render pipeline?
Using sort order by axes does not work very well.
I want to consider my 2d sprites like a 3d object when rendering

[stuck plinth]

it sounds like this might be a lot easier if you could just use 3d objects then 🤔 why do they have to be sprites?

[storm onyx]

Hello, I have a question. I have a prototype I want to test on my phone so I started android build. I have a pretty powerful pc but I have never had build take this long. The project is fairly small so It makes no sense to me why it is taking so long. It is the first build of this project but still. Any ideas? Unity is 2021.3.0

[timber flame]

Unfortunately, it is not my decision

I agree with you. Surely, 3d objects would be OK

I should mention sprites I mean 2d items have known 3d size and I want to use it and calculate depth value for each pixel and update depth buffer.
The game is a side game with 2d sprites with almost isometric shape. You can see top surfaces.
Items can be placed on top of each other

Why is my liveCount decreasing at the start of the game, even tho the action attack wasn't called yet

also when liveCount is less than 0 the attack action keeps running

also, liveCount decreases like crazy, like 40 times a second

[misty glade]

this is a code-beginner question - your liveCount is decreasing because it's public and serialized in the inspector

i don't know exactly what OnUpdate is from the task library you imported, but if it's not synchronized to unity's update cycle it's.. gonna run many times before the unity coroutine does

nothing in your code here looks like you need another library.. this is just pretty basic programming.. put all that junk in the overridden methods into Update() and Start() and clean it up and it should work just fine: make the public liveCount private, put brackets around your if statements, etc:

            if (liveCount == 0)
                isAttacking = false;
                return TaskStatus.Success; // No!

I can log in on windows tho

Not a code question, check Unity Status https://status.unity.com/

Sorry for wrong chat question. I'm still trying and isn't working by the way.

Yeah I get the same data. Seems like a Linux issue if it loads fine from Windows. I confirm that the Hub download page is accessible to me (win 10)

Actually just accessed it, the hub, had to install other version that wasnt compatible , had to instal a library and install a most recent version of the hub in order to access it Much appreciated for the support @fresh salmon 🙂

[ruby salmon]

anyone know how to implement your own OnComplete type thing, i have avoided coding these my whole time, not even sure what its called, a delegate maybe

something like: StartCoroutine(doAPIAction(() =>
{
Debug.Log("onComplete");
}));

and doAPIAction might be IEnumerator doAPIAction( Action onComplete)// = null)
{
_("doAPIAction");
yield return new WaitForSeconds(2);
onComplete.Invoke();
}

the idea is that once the doAPIAction is finished it calls the code where i have printed onComplete

just looking for docs but hard to search for when u dont know the terms 🙂

[sly grove]

sure you pretty much had it in that latter one

pass in a delegate

call the delegate at the end of the coroutine

[ruby salmon]

thanks! yeh but im getting a null somehow

[sly grove]

wdym by "getting a null"?

[ruby salmon]

at least i know what its called now

in the console it shows nullReferenceException at this line StartCoroutine(doAPIAction(() =>

NullReferenceExceptions are always the same

Since we're in #archived-code-advanced i would expect one to know how to investigate and solve them tbh

[ruby salmon]

trust me i do but i have never tried to use delegates

[sly grove]

you are dereferencing a null reference on that line

[ruby salmon]

i cant understand what is null

[sly grove]

find out

attach the debugger

[ruby salmon]

been a long time since i used a debugger 🙂

[devout hare]

On that line nothing can be null so either your actual code is something else or the error comes from a different line

[ruby salmon]

yeh thats what i was thinking

thats what i dont understand 🙂

[sly grove]

if you're doing all this in a one-liner, it could either be in the actual StartCoroutine line OR the lambda itself

[devout hare]

Show the actual code and the full error message

[sly grove]

hard to say without seeing the actual code and error yea

[ruby salmon]

pretty much just this https://pastebin.com/msKqPYPp

[sly grove]

show actual code

and actual error message

[sly grove]

Looks like you';re creating a MonoBehaviour with new based on this little snippet

[ruby salmon]

yeh that is the code, error is NullReferenceException

perfect it works, been shying away from that syntax for ages

[umbral bloom]

Hey guys. I've been looking for a method that loads all assets from a folder but I haven't found one.
So I've made my implementation. What do you think? Is it optimised?

private T[] LoadAssets<T>(string path) where T : Object
    {
        string[] foundAssets = AssetDatabase.FindAssets($"t: {typeof(T).Name}", new[]{ path });
        string[] assetPaths = foundAssets.Select(AssetDatabase.GUIDToAssetPath).ToArray();
        List<T> result = new List<T>();
        for (int i = 0; i < assetPaths.Length; i++)
        {
            var loaded = AssetDatabase.LoadAssetAtPath<T>(assetPaths[i]);
            if(loaded is not null) result.Add(loaded);
        }

        return result.ToArray();
    }

[stuck plinth]

there's a lot of unnecessary copies and allocations here, it's editor code so it doesn't matter too much but there's lots of room for optimization

[umbral bloom]

So I can use LINQ Chaining to prevent unnecessary allocations?

[upbeat path]

LinQ does not work that way

[stuck plinth]

well, you are collecting stuff to an array unnecessarily, so you could save a bit of allocation that way, but it's not just that

[umbral bloom]

How about this?

 public static T[] LoadAssets<T>(string path) where T : Object
            => AssetDatabase
                .FindAssets($"t: {typeof(T).Name}", new[] { path })
                .Select(s => AssetDatabase.LoadAssetAtPath<T>(AssetDatabase.GUIDToAssetPath(s)))
                .ToArray();

[upbeat path]

OMG. May I suggest, as you seem to be concerned about performance and memory, you learn how c# actually works

[stuck plinth]

that's better than the previous version, you're missing your null check from before though

collecting to an array is generally less efficient than a list, so i'd probably make it return a list

this optimization is probably completely irrelevant compared to the cost of actually loading an asset from disk though

[umbral bloom]

But list has an array under the hood.

[stuck plinth]

right, but you need to know the exact size to allocate an array, so ToArray is building a list out of your sequence of unknown length, then allocating a new array to copy the results into

[upbeat path]

@umbral bloom One thing you need to learn, writing less code, which is what you appear to want to do, actually usually means writing less efficient code

[umbral bloom]

"It's 2020 outside and everyone is using .NET Core 3.1 so I decided to run some benchmarks with Benchmark.NET.
TL;DR: ToArray() is better performance-wise and does a better job conveying intent if you're not planning to mutate the collection"
https://stackoverflow.com/a/60103725

[stuck plinth]

maybe it is faster these days, but you'd have to benchmark this in unity which is very much not using the latest and fastest version of .NET 😅

actually that answer also corrects itself too:

the accepted answer is actually correct: ToList is faster in the general case, because it doesn't have to trim the empty space from the allocated buffer.
The results confirm that ToList is in most cases 10% - 15% faster.

[umbral bloom]

Let me do some benchmarks for netstandard2.1 moniker

Notice that .NET Standard 2.1 implements .net Core 3.0, 3.1, 5.0, 6.0, 7.0, 8.0

[stuck plinth]

you'd probably want to test using unity's specific version of mono

[umbral bloom]

What should I use for testing (benchmarking) purposes? UTF?

[stuck plinth]

there is the performance testing extension for unity tests, don't think i've used it myself though

[umbral bloom]

[gleaming lichen]

Hey everyone,

I'm currently working with colliders in my Unity project and I'm trying to implement a system where I use callbacks to trigger certain actions when objects enter or exit a collider. However, I seem to be encountering an issue where the callbacks are being invoked, but nothing is happening in my scene.

Class 1 :

Action<InteractableBase, bool> _action;
public void Init(Action<InteractableBase, bool> action)
{
  _action = action
}
private void OnTriggerEnter(Collider other)
  {
      if (!Utils.Helper.CompareLayerMask(other.gameObject, _layerMask)) return;
      if(other.TryGetComponent(out InteractableBase interactable))
      {
          _action?.Invoke(interactable, true);
      }
  }

Class 2 :

private void Start()
{
  inRangeInteractionCollider.Init(ManageVisible);
}
private void ManageVisible(InteractableBase item, bool add)
{
    item.IsVisible(this, add);
}

Any insights or suggestions on what might be causing this issue would be greatly appreciated! Thanks in advance!

please insight me 🥹 🥹
hahahaa

[tiny pewter]

no.....have you checked the method is being invoked first

[gleaming lichen]

@tiny pewter yeah it as been invoked

but it never enter in the method :

but i think i correctly setup everything so i dont understand

[lament salmon]

What does IsVisible do though?

[upbeat path]

how are you calling a private method from a different class?

[tiny pewter]

you can by passing it as Action

[upbeat path]

I meant this

private void Start()
{
  inRangeInteractionCollider.Init(ManageVisible);
}

Init is private

[tiny pewter]

oh didnt notice that

mb

[gleaming lichen]

oh sorry i mess up when i was writting this message (i rewrite the method for more visibility)

[gleaming lichen]

it change an UI element

but guys i think i found the error

I didn't want to polluate my scene so did that :

            GameObject visibleCollider = new GameObject("Visible Collider");
            InteractionCollider visibleInteractionCollider = visibleCollider.AddComponent<InteractionCollider>();
            visibleInteractionCollider.Init(visibleDistance, interactableMask, ManageVisible);

            Instantiate(visibleCollider , _orientationTransform);

[upbeat path]

yep, that would do it

[gleaming lichen]

it made dupplicates, may be some reference got lost lol

[upbeat path]

you need to use a delegate so you can add to the action rather than replacing it

[gleaming lichen]

do you have an example sorry 😄

[hardy jacinth]

No idea why, but when I try to add a row to DataTable, it seemingly violates the uniqueness constraint on a column. I have a bunch of classes inheriting from base class Property, and when I try to add second property, it throws:

ConstraintException: Column 'property' is constrained to be unique.  Value 'me.tooster.sdf.Editor.API.Property`1[System.Single]' is already present.

what's going on?

It's worth mentioning that I only used DataTable for the first time yesterday

here is how I currently set the table up:

DataColumn propertyId = new()
  { ColumnName = "property", DataType = typeof(Property), Unique = true, AllowDBNull = false, ReadOnly = true };
DataColumn propertyControllerColumn = new()
  { ColumnName = "controller", DataType = typeof(Controller), Unique = false, AllowDBNull = false, ReadOnly = true };
DataTable propertiesTable = new DataTable("properties")
  { Columns = { propertyId, propertyControllerColumn }, PrimaryKey = new[] { propertyId } };
// later
foreach(var controller in controllers)
  foreach(var property in controller)
    propertiesTable.Rows.Add(property, controller);

so if the uniqueness is not determined by reference, then by what is it determined?

is is serialized in some way?

by toString()?

[stuck plinth]

maybe the type's IComparable or IEquatable implementation?

that's how most system libraries work

[hardy jacinth]

I'm not sure if I'm even using a proper tool for the job. The data I have mostly fits "something like a table", because there are a bunch of other columns, so using a bunch of Dictionaries seemed weird — I also wanted to perform some sort of joins and use the feature of auto-incremented primary key.

[dusty wigeon]

Usually, you do not want to use Database locally because it goes agaisnt OOP principle.

But, yeah, usually.

[hardy jacinth]

the Property and derived classes are pretty basic and don't implement any IComparable or IEquatable directly, the only thing that might be of concern is possible [Serializable] annotation, but I will see in a jiffy if that's the core of the problem

[stuck plinth]

i would expect for something used as a table index you'd probably need to make it comparable anyway, if you haven't implemented it that might be why you're getting false duplicates

[hardy jacinth]

I am not using a db locally, I just wanted to store runtime important data in "something like a database" in memory, in the simplest way possible

[dusty wigeon]

I mean, not exactly sure how you are phrasing it but it really seem like a simple save system.

Are you having multiple people using the same database ?

[hardy jacinth]

it's rebuilt either way (for now) each time a hierarchy changes (used in editor only). My main and only use case was to store and access cached data from a hierarchy of game objects and their components

[hardy jacinth]

only me, and it's only a single DataTable, used for a single component running in the editor

maybe more info on why I even try to use it:

[dusty wigeon]

Yeah, exactly my points. I feel like the database is way overkill. Why cant you not just use POCO ?

[hardy jacinth]

I have a game objects with a script that defines a kind of "root". There are a bunch of child game objects with some kind of Controller derived component, and "root" collects them in the editor, assigns some unique data for each one (like a unique but human-readable ID for each one), a cache of all properties defined by children and which child defines them (for quick access), some metadata for them as well (again some unique under the root, human readable ID, an auto-incremented ordinal number for each one) and possibly other things as well. So I tried modeling it first with a bunch of Dictionaries/HashSets and POCOs, but looks like a bunch of them have to be created and some things have to be done manually. For example sometimes I want to quickly lookup by Controller instance, but other times I need to quickly look up by Property. This looked like a good use case for DataTable with primary keys, especially when I sometimes would need to join the data like Controller x assigned property IDs

[scenic forge]

Unless I'm missing some context, your querying requirement doesn't require anything specific of database, LINQ works regardless of the underlying storage.

[hardy jacinth]

yeah, I'll use regular dictionaries/sets and POCOs instead of DataRable for now. I'll them until I learn more about them.

[mellow plinth]

Given a NavMeshPath, how can I know if it contains OffMeshLinks?

[upbeat path]

I can only thing of one way, calculate the path twice, once with links enabled and once without and compare the paths generated

[mellow plinth]

That is terrible 😨

haha

Is there any other way?

[upbeat path]

yes, it is

[mellow plinth]

I thought about using NavMesh.RayCast on each corner and if there is a hit, then there is a link. But that is not perfect and I noticed several false positives and positive falses.

[upbeat path]

well, yes, but it's even worse

[mellow plinth]

What thing?

[upbeat path]

check every corner in the path, find the corresponding gameobject and then check for a NavMeshLink component

[mellow plinth]

How do I find the corresponding gameobject?
I guess I should take the start, end point and width of each link and check for each point it it's in the start or end line of the link?
That sounds kind of expensive and error prone?

[upbeat path]

expensive, yes, error prone, not so much, worth doing it, I doubt it

[mellow plinth]

Ok

[upbeat path]

question. why do you want to know this?

[mellow plinth]

Then it won't take me much time because I already have a code that does that to get the NavigationLink (custom class of mine) from a OffMeshLinkData. So I should adapt it a little

[mellow plinth]

When my enemies patrol, they move to random locations, but I don't want to move then to a random location if that requires jumping. Instead I want get a different point.

[upbeat path]

then just set the agent to not use navmeshlinks, then you will get a partial path back if links are necessary

[mellow plinth]

1. How do I make NavMesh.CalculatePath to not use links?
2. My links also contains custom data, so I don't want to just know if it has a link, but which one, so I can read tha data and take decisions with it.

[upbeat path]

https://docs.unity3d.com/ScriptReference/AI.NavMeshAgent-autoTraverseOffMeshLink.html

[upbeat path]

tbh what I would do is add a trigger collider to your links and then let that tell you if it's been hit

[mellow plinth]

I want to know this before getting hit. I want to know if during the planning of the path

[upbeat path]

not possible unless you implement a custom version of A*

my first option might be your only solution but even that wont work if there are multiple links to traverse

[mellow plinth]

I will iterate over each corner of the path, and iterate over each navigation link and check if the start and end point are in the start or end lines of the links

[lament salmon]

I remember reading somewhere that you can store the link positions in a List and then check each path corner and see if they match any link's position

Haven't tried that myself but it's worth a try

[mellow plinth]

Yeah, that is what I will do

[lament salmon]

Oh I missed your latest message, sorry

hey guys, i made an android game and i wanted to publish it on google play store, but when i tried to put the aab file it says that its bigger than 200 mb and doesnt let me, to avoid this i now use addressables, but now i want to get the addressables from a server, is there a way to use addressables with play asset delivery ? if not can anyone help me make the unity cloud content delivery work ? i have made the code to load the addressables and stuff i just need help with getting it from the server, its giving me an invalid URI: invalid port specified, even though i chose the correct loadpath that unity gave me in the addressables profile

[upbeat path]

do not cross post

[lyric isle]

I'm making a multiplayer game and I can't use any singletons for my WorldManager instances because the server unity instance has multiple worlds loaded and running in parallel. I'm thinking of just having every gameobject call FindObjectOfType<WorldManager>() to get their scene's local WorldManager but i feel like there is a better way I'm just not seeing.

[main finch]

Hi all,

I'm working on a custom package, it has 2 dependencies; Input System and TextMeshPro. I've successfully got the package downloading the dependencies, however, it appears that the files know nothing of the packages. To address this I have added GUID references in the assembly file. (Unity.InputSystem, and Unity.TextMeshPro). This resolves the TextMeshPro errors, but I am still getting an error for the Input System ( error CS0246: The type or namespace name 'PlayerInputActions' could not be found (are you missing a using directive or an assembly reference?)). For context I had developed this in the Assets folder successfully, then moved it into the packages directory which has caused these issues to show. I've also got it setup on github so I can use git url to install it.

[main finch]

Are the gameobjects created by the worldmanager?

[upbeat path]

is PlayerInputActions not your own class generated by the new Input system?

[lyric isle]

Are you sure "PlayerInputActions" isn't a generated c# class from your input actions asset? because I don't think anything in the inputactions system uses that exact type or namespace.

[main finch]

ah yeah, I think you guys are right 😅

I had it in the samples folder 🤦‍♂️ I guess this just shows that my package still needs some work. Thanks!

[lyric isle]

They aren't, but I have considered instantiating all the gameobjects through the worldmanager and then having it assign itself to them something like
Transform newObject = Instantiate(prefab)
newObject.GetComponent<IWorldObject>()?.SetWorldManager(this);

[main finch]

Maybe you could create an event within your spawner/setup script and have the worldmanager subscribe to it's spawn event and setup the dependency through there?

[hushed fable]

Serializing whatever references you can and assigning dependencies on instantiate is probably the way to go. Unity also has events for scene loading and methods for getting the objects within that scene, so you can also do this across scenes to facilitate multi scene setups.

[lyric isle]

I guess I'll stick with that then. I've also toyed with the idea of a static dictionary for references, but that would probably overcomplicate things.

[trim glade]

Hi, I'm trying to set the "build configuration" setting from the WSA build settings option via code. I seem to be wanting to use Environment.SetEnvironmentVariable, but I can't seem to find what the variable is named for me to reference. Could anyone help me out? Thanks

Hi again,

I made a sample for my package, but upon moving it into the proper folder layout (Within the packages folder, next to the Runtime directory), the prefabs have broken themselves, possibly because the scripts used in the prefabs derive from the Core files, but are located in the Samples folder. Is there a way to move the prefabs without breaking the link?

[dusty wigeon]

Really strange, usually prefab are linked through .meta files meaning that as long as you move everything it should not break.

[brisk pasture]

whats lost prefab references, or the componets on them broke

[ashen yoke]

Hi It must be common to have a list and then realise you often want to find elements of that list by Id so you add a dictionary (because you still want a list for fastest traversal from start to end). Is there not a typical List/Dictionary combo container?! Must you choose...

[tiny pewter]

c# dictionary is open hash table with single linked list.....
afaik uthash use double linked list so you can traversal the hash table at exactly theta(number of item) time

but ofc, double "pointer" (actually is integer type) space

[ashen yoke]

I know the basis for a dictionary, but I must test the speed of looping through dictionary items vs a list to see if not worthy of keeping a list. Ideal data container would have [index], fast iteration, find by Id/key!

[scenic forge]

Honestly I would not bother, if you are worried about it because of performance, have you profiled it and positively identified the iteration is the performance bottleneck? Otherwise, it feels very much like premature optimization.
There are also information missing. You mention that you want to look up items by id, and want to iterate over the items, but you didn't specify 1) how many items we are talking about and 2) do you need to iterate over the items in any specific order (eg insertion order?). It will change the answer.

[brisk pasture]

benchmark it

90% chance you are overthinking it

[ashen yoke]

you are right I will benchmark, also 90% it actually does not matter which I use as not significant!

[stuck plinth]

there's SortedList, which is kind of both, although it's not necessarily as fast for lookups as a dictionary

[brisk pasture]

also does order even matter for you

assuming not, that its lookup by key, or you just want to loop them all

[scenic forge]

Exactly, the amount of items and the iteration order are two important piece of missing information.

[brisk pasture]

toss a few million things in a dict, and a list

measure how long to iterate it all

there is your answer

[ashen yoke]

thanks I think since <1000 there is little issue - BENCHMARK!

[brisk pasture]

write it in a way it does not get optimized out

so pass it to something each iteration

but do the same thing in both examples

[scenic forge]

1000 items is trivially small, and you still haven't specified what iteration order you need.
If you don't care about iteration order, keep in mind you can literally just foreach the dictionary. Whatever you do with each item will likely far outweighs the cost of iterating that tiny 1000 item dictionary that I wouldn't even bother benchmarking it.

[brisk pasture]

the amount of worry feels more like procrastination then anything to me

would not worry about 1000 iterations, would just try and ensure you are not doing work more times then required

[main finch]

The components on them have broken. For example, "MenuManager.cs" is part of the Samples directory, while this is within the Assets directiory, all is fine, as soon as I move it to the packages directory the references are lost, and it appears the code is not being compiled while in the folder. Sorry for the delayed response!

[main finch]

This is my first time making a package properly so I've probably made a rooky mistake somewhere tbh!

[stuck plinth]

just in case, did you move the metafiles too when you moved the scripts?

[main finch]

yeah, I moved the entire Samples folder from under assets to packages (well the custom package within packages). I was trying to mirror it so moving it would cause no issue.

[brisk pasture]

it feels like your asmdef references are messed up

[main finch]

I have "auto referenced" ticketed and "Use GUID" with the input system being included.

but that asmdef is in the runtime folder, should there be one in samples?

[brisk pasture]

is there scripts in the samples folder?

[main finch]

yes'

[brisk pasture]

could try tossing one in there, then explicty creating a reference to your main asmdef

i have not done pacakge stuff in like a year i forget if the samples folder in it would act differently or not

compared to just a folder in assets

[main finch]

I think it is defo acting differently, but when I look at the docs, it doesn't mention having a asmdef file in there, I will try it tho

[main finch]

ok, it's sorted out the linking and I can open it in vs studio again, that was defo part of my issue. So I guess, whenever code/prefabs are included in the samples, it would be common practice to include an asmdef file?

I need help setting a line renderer that always draws its points to the same target regardless if its game object rotates or not.
(Pic 1)Here I have a bunny ninja moving towards the player and the line renderer is pointing to the right direction, but were he to rotate to move around an object, the line renderer rotates, too. So it's always pointing forward. How to calculate it in a way that it accounts for transform's rotation?
If it makes life easier, he will only ever rotate on the Y-axis.

[sly grove]

set your LineRenderer to use World Space instead of Local Space

and just set the points according to the world space positions desired

alternatively, continue to use local space but convert the desired points into local space before assigning them to the LR

the key is just to be consistent and not mix up world space and local space positions

[proven willow]

Oh, dang! I didn't even notice the boolean there. Thanks! 😂

[proven willow]

Working properly. Thanks!

[torn basalt]

Hey, I have a question about UnityEvent and dynamic parameters. I am setting up a statemachine that uses UnityEvents. Say the event is UnityEvent<float>OnSomeEvent. When the state matches what the listener is waiting for then the event is fired and sends a float value from a list of choices based on the current state. This all works but I not want to tween to the float that is sent from whatever the current value of the dynamic parameter is. Is there no way of getting access to the dynamic parameters? I tried the getpersistent target and such but there is no way to get it there without knowing all the possible types that could be used.

[compact ingot]

Generally the invoker of an event should not care what the listener wants to hear. Therefore this whole design, while based on unity events, is flawed. They superficially look like editor assigned method calls, but really they are an implementation of the observer pattern.

In your case it would make sense to make a custom state-message-bus-type thing that’s suited to your design.

[bleak citrus]

why not just have the receiver figure out how to tween the values?

the invoker's job is to announce a target value

[compact ingot]

there‘s definitely a use case for a state injecting behavior into listeners, say for agents that want to interact with a widget.

but only in the abstract ofc

[torn basalt]

That would require an additional script for the listener

right now its just a component that listens and can responds by setting the values of the dynamic parameters defined in the event (in editor). allows me to keep the relevant items in one place. Though I am not opposed to changing things up which I may have to. IT sucks because all I want to do is figure out what the current value is.

Oh well. Can't haqve everything

This is an example of what I am testing now. But default value means that I have to set some arbitrary value

            float duration = dataTarget.duration;

            Vector2 defaultValue = Vector2.zero;

            DOTween.To(() => defaultValue, x => defaultValue = x, targetValue, duration).OnUpdate( delegate { _vect2Event?.Invoke(defaultValue); });```
