[mighty ivy]

It uses "WorldToScreenPoint" to draw the arrow in the screen where the object is, then with fancy math and adjusting for canvas scale it clamps it in the edges of the UI

It works flawless for close waypoints. The problem arises when waypoints are very far: as you can read from the code I forced the Y of the waypoints to be the Y of the player (the camera is above the player, it's a top-down with a 45° angle camera), to be sure that the object is never under the camera. But with far away objects, the object can still be behind the camera, even with the same Y... Has anyone got any solutions?

When the object is very far the arrow points on the other side

For reference, that's a screen of the game with the tracking arrow in the upper left edge (a bit hard to notice when it's not moving). It's tracking a very far away waypoint: the arrow should be in the bottom right edge.

[marsh mesa]

My camera renders UI even when it's disabled in the culling mask

Im trying to do a camera stack, but the main camera doesnt stop rendering the ui

it happens when the stack is empty too

All of my ui is on the correct layer, and is on a canvas

here's how it looks when it set to render nothing

what could be the problem

[mossy snow]

canvas is using overlay render mode or screen space with no camera assigned

set it screen space and assign a camera

[marsh mesa]

Ooo thanks!

[urban summit]

I just opened a project and it already says that I have a problem with VS code, would this effect my code in unity?

[quartz folio]

Impossible to say. It's not a good idea to have non-normal characters in directories anyway.

You may find later down the track issues with building

I'm not sure what else you have but . should be reserved for file names, not in directories

[urban summit]

Well my file name is TCG ; Card gam anything unusual with it?

[quartz folio]

; is not a normal character to have in paths either

[urban summit]

I see i'll remove it immediately then, btw don't i need to delete the project entirely or just change the name of the folder?

[quartz folio]

You should just be able to close Unity and rename the directory

[urban summit]

alr, thx man much appreciate your help!

[lean sail]

Its best to just use short path names and no space at the end though I typically use no spaces at all.
Not sure what OS youre on, but if you create a file on Linux for example, windows might have issues with that naming and others could have trouble using version control with your project

I had similar issues at work where someone on another OS had a space at end, or a 260+ character path and I just couldn't interact with it

[urban summit]

No worries, my OS is Windows 11, I didn't k now before that we should not include spaces in the folder's name, thx for the advice i'll take it into account

[quartz folio]

I'm happy to use A-Z a-z _ - and spaces (as separators only)
I actually think I was mistaken and . would also be fine, it's probably complaining about the semicolon but best to be safe and avoid it too

[lean sail]

Yea spaces are allowed, just not as the last character I believe. The only reason I avoid spaces is habits from the past

[shadow cradle]

is it possible to change vfx graph props that cant be exposed from code? like shape volume/surface

[earnest gazelle]

Can we access the parent of a cloned gameobject from nested children without referencing it in the inspector explicitly?

[night harness]

Yes (via transform.parent) but it's almost always avoidable and might be a sign that your approaching something in a non-preferable way

[earnest gazelle]

You did not get my point

I said nested child, maybe it is immediate child or not

[steady bobcat]

you can traverse the "tree" in both directions

[earnest gazelle]

I know I can check transform.parent iteratively to find

[steady bobcat]

you can get components in children or get the transforms children

[night harness]

once the object is instansiated, there is no information unity retains for the child to figure out what parent is the prefab parent specificially

[earnest gazelle]

but it is not ideal, so the answer we are not able to access the root of cloned gameobject directly in the code

[night harness]

we are

but the root isn't always going to be the prefab object

eg. if you instansiate something as a child of another object

it's on you to determine which parent you care about

[earnest gazelle]

Example:
Cloned gameobject (root)
child
child
child
child
child

[night harness]

sure but

Parent you spawned the prefab under
  Cloned gameobject (root)
     child
         child
    child
        child
          child

if this happens what do you want to find

[earnest gazelle]

No, I just spawn a gameobject in the scene and I wanna access the root of gameobject from codes assigned to some children, easy

[steady bobcat]

i pointed out this is possible, what is the confusion?

[earnest gazelle]

You said transform.parent

[night harness]

you can use transform.root but this will not work if the object is spawned under any sort of other gameobject

[steady bobcat]

transform.GetChild(), transform.parent. you can do this all from any transform

you can walk up/down as you desire

[earnest gazelle]

Thanks, yes it is OK transform.root

[night harness]

sometimes it is

[earnest gazelle]

but maybe buggy because the spawned gameobjects are in another gameobject, I mean when spawning, pass a parent to them!

[steady bobcat]

correct (that its sometimes): https://docs.unity3d.com/6000.1/Documentation/ScriptReference/Transform-root.html

If you have a component on the "prefab root" you can locate this

[night harness]

I would strongly recomend considering doing whatever your doing in a way where the parent object is doing this work, not the children

this can include the parent object informing the children that it exists

eg. dont make the children find the parent make the parent find the children (and perhaps tell the children where it lives)

[fiery steeple]

Is it possible to construct a color from hex code ?

[steady bobcat]

yes https://docs.unity3d.com/6000.1/Documentation/ScriptReference/ColorUtility.TryParseHtmlString.html

[fiery steeple]

html = hex ? 🤔

[steady bobcat]

yes, read the damn page 😆

[fiery steeple]

I'm really confused because it's a editor script 🤔

[steady bobcat]

its just their example

You can use it anywhere:

if (ColorUtility.TryParseHtmlString("#FF0000", out var newCol))
{
  //Do thing
}
else
{
    Debug.LogError("Parse failed!");
}

[fiery steeple]

But here I need it to be inside an array and apparently I need the "out var newCol" part so I don't know how to properly put it directly inside an array 😬

[steady bobcat]

You cant, you will need to write the result into the array post array creation.
If you check the doc page again for the function, it gives the result with an out variable. it returns bool which is the parse success result

You could also make your own function that wraps this and returns the colour as you desire

[fiery steeple]

argh 😬

[soft shard]

Isnt there also a Parse without the "Try", which should return the color without a out? Assuming that you are certain your providing valid data to the function

[steady bobcat]

not in ColorUtility

Unity probably did this due to Color being a struct

[soft shard]

Ah

[night harness]

        public static Color ParseHex(string hex) => ColorUtility.TryParseHtmlString(hex, out Color col) ? col : Color.white;

tada

[steady bobcat]

col may already be "white" as it should be default if parsing fails

[earnest gazelle]

Dude, it is about colliders. The children have colliders

but the code to do some logic is on the root

[night harness]

yup

hence why the children shouldn't be looking for anything

sounds like a great job for the parent

[steady bobcat]

😆 this really isnt hard to solve

[earnest gazelle]

Currently, I assign the root to the script in the children through inspector

[night harness]

ok

[thin aurora]

This would really not be the preferred way of doing it tbh (undefined/unexpected behaviour)

public static Color ParseHexOrDefault(string hex) => ColorUtility.TryParseHtmlString(hex, out Color col) ? col : default;
public static Color ParseHex(string hex)
{
   if (ColorUtility.TryParseHtmlString(hex, out Color col))
        return col;

   // Could also be a FormatException
   throw new ArgumentException($"The given hex value '{hex}' could not be converted to a valid hex.", nameof(hex));
}

[thin aurora]

☝️

Why this doesn't already exist, idk. Unity does everything only halfway so you kind of get used to doing this.

[fiery steeple]

Why does it say that color is never null ? 🤔

[thick terrace]

it isn't a nullable type

use the result of TryParse... instead

[last quarry]

Color is a struct. Structs can’t be null.

[fiery steeple]

like so ? 🙂

made it better 👍

[night harness]

though as rob and Fused have mentioned if your not interested in using the check to throw an error or log that tryparse function probably returns white if it fails anyway so you could just do

        public static Color ParseHex(string hex)
        {
            ColorUtility.TryParseHtmlString(hex, out Color color);
            return (color);
        }

not anything really different just mentioning for the sake of mentioning

[last quarry]

It doesn't return white

[thick terrace]

does it return white? i would assume not lol

most likely it returns default(Color)

[last quarry]

It returns black with 0 opacity

[night harness]

ah black?

[thin aurora]

If you read up I already gave a proper solution

You can return Color.White, but this just leads to confusion as to why it's suddenly white in the future

Better to just use a proper check and return either defualt or throw an exception if you want better behaviour (I'd argue returning default is also bad). Just make sure the hex color is always valid

[fiery steeple]

Thanks 🙏

[misty latch]

[delicate ravine]

trying to debug an issue with my game

public void HideAndUnhide()
{
    HidyHole hidyHoleScript = hidyHole.GetComponent<HidyHole>();
    BoxCollider playerCollider = gameObject.GetComponent<BoxCollider>();
    BoxCollider hidyHoleCollider = hidyHole.GetComponent<BoxCollider>();
    if (isHiding)
    {
        Vector3 outPosition = hidyHole.transform.position + hidyHole.transform.forward * pushDistance;
        outPosition.y = 0;
        transform.position = outPosition;
        isHiding = false;
        hidyHoleScript.HidingPlayer = null;
        Physics.IgnoreCollision(playerCollider, hidyHoleCollider, false);
    }
    else
    {
        Physics.IgnoreCollision(playerCollider, hidyHoleCollider, true);

        GameObject hidingPlayer = hidyHoleScript.HidingPlayer;
        if (hidingPlayer != null && hidingPlayer != gameObject)
        {
            PlayerController hidingPlayerController = hidingPlayer.GetComponent<PlayerController>();
            hidingPlayerController.HideAndUnhide();
            hidingPlayerController.StunPlayer();
        }
        hidyHoleScript.HidingPlayer = this.gameObject;
        transform.position = new Vector3(hidyHole.transform.position.x, 0, hidyHole.transform.position.z);
        isHiding = true;
    }
}

I am trying to move the player to the side of the hiding place when the player unhides, but i am getting inconsistent behavior. sometimes it moves to the side, but sometimes, it remains in the center of the hiding place. I tried multiple things but not able to figure out what I am doing wrong

[vestal arch]

lol why'd you highlight your code as python

[leaden ice]

what debugging steps have you taken?

[delicate ravine]

oops, generally i code in python hence accidently did that

[vestal arch]

anyways first step here would likely be to just start debugging, adding logs and such to make sure values are as expected and the right branches are reached

just to figure out what's happening - you can move on to the why and how from there

[delicate ravine]

I tried printing out the positions, so after changing the transform.position, the position of the character is printed correctly, but when i print the position at the start of update, it shows it as the position of the center of the hiding place

[leaden ice]

you should generally not be modifying the Transform of your player directly if it is using a Rigidbody

that issue may be coming from the Rigidbody, or it may be coming from some other code you have.

[delicate ravine]

I also tried doing controller.Move, but that was not moving it at all

[leaden ice]

wait you have a CharacterController?

[vestal arch]

you have a charactercontroller and a rigidbody?

[leaden ice]

HUGE info you should have shared lol

1. If you have a CC, the player should not have other colliders (such as a BoxCollider)
2. If you have a CC, you cannot move the object via transform.position without first disabling the CC

[delicate ravine]

you need rigidbody for collisions right? I am not using physics so i have set it to kinematic

[leaden ice]

A rigidbody is for physically simulating an object

you don't need a Rigidbody if you are using a CharacterControler

[vestal arch]

uh #🏃┃animation? this is a code channel

[prime vapor]

oops, my bad! moving this there

[naive swallow]

Very thorough question though. Almost makes me wish I knew the answer just so I can encourage that kind of full on description in the future but I am not an animator

[delicate ravine]

but the collider for cc is a cylinder right? i need a box for my character shape

not cylinder, capsule i mean

[vestal arch]

you can have an rb or a cc, but not both controlling the character. both components control the transform (hence the "don't modify the transform" thing) so they will end up fighting

if the cc's cylinder is a dealbreaker, you could use an rb with a box collider instead

[delicate ravine]

i tried doing Vector3 move = outPosition - transform.position and then controller.Move(move) but that is not moving it at all

[fiery steeple]

Isn't it possible to create a dictionnary and add values directly like in an array using {} and "key" for the key ?

or something like this ["key"] ?

[delicate ravine]

is something wrong with my Move?

[leaden ice]

Then you can't use a CC

CC is a capsule, no choice

[leaden ice]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/how-to-initialize-a-dictionary-with-a-collection-initializer

[delicate ravine]

removed that and adjusted capsule in similar shape as my box, but the move thing doesnt work

[leaden ice]

what move thing

[delicate ravine]

this

[leaden ice]

wdym "adjusted capsule"?

[leaden ice]

show the code that you are trying now? Did you remove the CC, or you disabled it?

[delicate ravine]

adjusted radius and height

[leaden ice]

so the CC is still there

[delicate ravine]

that disable is unrelated, i was typing something else and accidently sent

[fiery steeple]

in my case I don't have a class so I don't have fields to attribute those colors too. So that links doesn't help that much except if I'm missing something 🤔

[leaden ice]

you need to disable the CC to move it via teh Transform

[delicate ravine]

I replaced transform with controller.Move

[leaden ice]

You are definitely missing something. The link shows you exactly how to initialize a Dictionary. IDK what you mean about not having fields.

[leaden ice]

that's not going to help you when your other code is calling CC.Move already

the correct answer here is to disable the CC and then move the object via the Transform

[delicate ravine]

oh, I thought disabling it would be not a proper thing to do

[fiery steeple]

Like in the example he has a StudentName class having multiple fields like FirstName, LastName and ID, which in my case isn't the same as I don't have a class and don't want to create a class with each color key being a field of that class. Here I want the key to just be a string not a field from a class 😬

[delicate ravine]

disbaling it and then reneabling does work

[leaden ice]

The code in the link is just an example to show you the syntax

obviously you would use whatever objects you actually need for your Dictionary

you're focusing in on the StudentName class which is not important

[fiery steeple]

I added curly braces around each entry but still complains about they key

[leaden ice]

you're not following the syntax from the example code

        var students = new Dictionary<int, StudentName>()
        {
            { 111, new StudentName { FirstName="Sachin", LastName="Karnik", ID=211 } },
            { 112, new StudentName { FirstName="Dina", LastName="Salimzianova", ID=317 } },
            { 113, new StudentName { FirstName="Andy", LastName="Ruth", ID=198 } }
        };```

They are not using = like you are

for you each row would be:
{"DARK_GREEN", Utilities.ParseHex("#0F9D58")} for example

{key, value}

just like the example

[fiery steeple]

thanks 👍

= symbol is the thing that confused me

[leaden ice]

new StudentName { FirstName="Sachin", LastName="Karnik", ID=211 } }

you can ignore everything inside here

it's irrelevant to the dictionary initializer

it's just value basically

they were just combining an object initializer with the dictionary initializer to show how you can use them in conjunction

[fiery steeple]

they should put a simpler example

[leaden ice]

probably

[karmic stone]

Hello! Im using the Animation rigging package for ik animation during gameplay. I want to be able to change weight of the target during gameplay. In editor i assign 0 rotation / position weight, and when i tell it to, set target rotation weight / position weight to 1.
However, it just, doesnt set the weight in code. The debug.log gets called, the line before gets called, but the target rotation weight / position is still 0 when looking at the component after. How do you set the target rotation / position weight?

rightHandIK.data.target.SetPositionAndRotation(RightHandWrist.position, RightHandWrist.rotation);
        Debug.Log("OnStateEnterWateringCan called, setting target position and rotation for right hand IK.");
        rightHandIK.data.targetRotationWeight = 1f;
        rightHandIK.data.targetPositionWeight = 1f;
``` (If this is better in animation just lmk, chose this bc its code)

[leaden ice]

TwoBoneIKConstraintData is a struct so pretty sure you need to do this:

TwoBoneIKConstraintData data = rightHandIK.data;
data.targetRotationWeight = 1;
data.targetPositionWeight = 1;
rightHandIK.data = data;```

[karmic stone]

OH its a struct! thats, a dumb mistake on my part. thank you for the info.

Wait, that didnt seem to work either. gonna try a more thourough google.

TwoBoneIKConstraintData rightHandIKData = rightHandIK.data;
        rightHandIKData.targetRotationWeight = 1f;
        rightHandIK.data = rightHandIKData;

(found something talking about it in case anyone else needs it. https://discussions.unity.com/t/animation-rigging-package-unable-to-change-weight-at-runtime/804724/9)

answer to my question is probably this:
looks like doing rig weight changes during animation transitions is illegal. i’ve wrap code with weight changes into coroutine with animator.IsInTransion check and now all works like a charm

[stone rock]

Is there a proper way to not have these dropdowns on serialized classes without a custom editor?
I would like the settings just displayed in the feature without it being under a dropdown

This is that class.

    [Serializable]
    internal class SharpenSettings
    {
        [SerializeField] internal float sharpness = 0.0f;
    }

    public class Sharpen : ScriptableRendererFeature
    {
        [SerializeField] private SharpenSettings m_Settings = new SharpenSettings();

        private SharpenPass m_SharpenPass = default;
        private Shader m_Shader;
        private Material m_Material;

[leaden ice]

Not without some editor scripting of some kind or a plugin, no.

A PropertyDrawer is the most straightforward approach

[stone rock]

Ok, will do it with editor scripting then

[swift falcon]

I was thinking, what's the best way to handle attribute modifiers (like items giving + speed)? A list of the modifiers, that are all sumed/multiplied when getting the final value (and are removed when the item is unequiped), or just a simple variable that is modified on equip and on unequip?

[leaden ice]

I prefer to use the list of modifiers, especially if you have multiplicative and additive multipliers separately.

Otherwise it's hard or impossible to recalculate the value when an arbitrary modifier is removed or expires

[swift falcon]

yeah that's true

makes sense

[drifting zealot]

Hello guys, one question about virtual properties, Imagine that I have a virtual property with its respective field, in a child class I want to override the Set method to add a small validation, but of course, to access the original field of the parent class it must be public, which will allow it to be accessed from the child class, enabling access without using the set method, allowing them to bypass the validation. Is there any way to avoid this? I was thinking about having each child class define its own field, but I'm not sure if that is the best way to solve this.

[vestal arch]

it must be public
no it doesn't
access levels aren't limited to public and private
sounds like you'd want protected here

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/accessibility-levels

[drifting zealot]

Hey, Thank you!, This is exactly what I needed! this solved my issue

[naive swallow]

If I want to exclude a specific collider from a raycast is there any better way than storing its old layer, setting it to a layer that the raycast will ignore, then setting it back? Ideally, I'd like to have them all on different layers so I wouldn't need this switcheroo, but for Render Feature purposes I need them all to be on the same layer

[soft shard]

Not sure if you can specifically exclude a collider without layers, but maybe what you could do is use a non-alloc raycast, which means it will be included but you can then loop through and filter out the specific collider after with a second "exclusion" list?

[naive swallow]

That might work. I dunno what's lighter, that or the layer switcheroos. I'll need to check

[lyric veldt]

does anyone know whats the best way to procedurally spawn objects in a maze, like if i want to spawn a cabinet that like hugs the wall whats teh best way to do that

[rigid island]

is maze premade ?

[lyric veldt]

no

is procedurally generated too

do you want the code

[rigid island]

could probably get all surfaces that have a specific normal direction then shoot some rays and casts and figure out placement

[lyric veldt]

hmm, im not sure how to do that though

[rigid island]

break down each part, learn them separately then combine them into your final usecase

procedual anything can be tricky, if the walls are prefabs you could potentially get away with placing some premade gameobject as empty points to potential spawns, then you can put them in array and pick random one when generation is done

[lyric veldt]

do you think if is easier to just create a bunch of rooms and spawn those instead, or procedurally create a maze, and randomly spawns the object in with rules

or I thought of a new idea

I'm thinking of using a hybrid system for the game, like the maze walls will be procedurally generated using my current algorithm, but instead of randomly placing objects, each floor tile will have several possible preset variations, and I will setup rules for how these floor should spawn, like when there is a deadend have a floor tile that contains chests etc

[rigid island]

depends on the situation, I found rooms/sections easier sometimes, cause they can have their own local rules for specific props

[hexed pecan]

Can't you just use a separate gameobject for the colliders instead of having them on the renderer gameobject

[shell scarab]

is this a thing now or is rider just bullshitting me? InitializeOnLoad should be enough no?

[somber nacelle]

that's for when you have Domain Reload disabled when entering play mode. static members do not get reset with domain reload disabled and since that is not readonly it's possible to change the object stored in it. so you'd want to reset it inside of a method called with RuntimeInitializeOnLoadMethodAttribute

[shell scarab]

would that be in project settings? I haven't touched it.

or preferences?

[somber nacelle]

even if you haven't touched the setting you've got analyzers that check for it.

[shell scarab]

ah

[somber nacelle]

this appears to be from the Project Auditor package's included analyzers

[shell scarab]

that would make sense as to why I haven't seen it before, i did just install it

except I haven't checked off 'Use Roslyn Analyzers' so maybe Rider is just using them anyway

Does anyone know how to make this spawned rotated the right way, because currently is rotating based on the closese wall, but i dont want to do that as you can see here

i want it spawned like this

[lean sail]

i have absolutely no clue what you're trying to show with the screenshots. What is object is "this"
you coded it to work with the closest wall. Dont do that if thats not what you want

Im guessing AI code?

[lyric veldt]

so basiclly is a

maze generator right

and i want to have different object on the floor,

so i figured I should just randomly generated different like "presets" of the floor, and spawn it on the floor

one issue im having right now is I want the object to have a whole wall on the back

so i tried using a point to trying to figure out the closes wall

but if the wall spawns vertically

it will rotate the wrong way

so something like this

[lean sail]

you can type in one message instead of 10 different ones.
also part of this is still unclear like what you mean by "if the wall spawns vertically" or really what your end result should look like. did you write this code? Parts of it are very questionable. If all you're doing is spawning the door in this location, then rotating it, that isn't going to move them closer to the other wall which is what it seems like you want.
stuff like this is probably easiest if you step through with the debugger and see whats happening line by line so you can see where your algorithm is going wrong. Also reconsider that logic around line 35. you seem to be calculating the direction of the raycast, when you just used the direction in the raycast.

Or maybe it seems like obj is the floor in this case? In that case then its still a bit odd what you're doing with this orientation object. Maybe some of your values there aren't aligning to what you think it may be. I notice you also have Debug.DrawRay in there. Id suggest drawing it as green or red conditionally if it actually hit an object.

[lyric veldt]

sorry bad habit, anyways what i meant by if the wall spawns vertically is like if you looked at the maze from the perspective, and I did use ai for only the object rotation part of the code, which I just follow the direction the ai gaved and it kind of worked i guess

[lyric veldt]

yeah the obj is the floor in this case, i have another idea, which i dont think is the best but probably would work

so basiclly instead of raycasting one time, i just have a list of empty object that raycast the back of the drawer or whatever, and if lets say all 3 of them hits a object with a wall tag, it sets its rotation there

what do you think of this possable implementation

[lean sail]

sure, that is something you can do. Thats seemingly what you were already trying with that orientation object.

you should really learn to debug rather than just copy pasting AI, especially if you dont understand what the code is doing

[lean sail]

since this is maze generation, itd probably be better if this floor already knew where walls are in regards to it. though im not sure what kind of data structure or algorithm you're working with there

[scenic wraith]

I was surprised to find yesterday, that assigning a value to a property was 4x slower than assigning to a field - at least when using a Stopwatch to benchmark.

I had thought JIT compilers basically give properties and fields near identical IL. Can anyone explain why assigning a property could be so much slower?

[sturdy holly]

jus tnoticed I am not seeing the debug visuals for wheel colliders in 6.x

[vestal arch]

the overhead of calling a function, probably

[scenic wraith]

I would have thought the JIT compiler would inline the property’s method body, eliminating the need for a separate function call. head scratch

[vestal arch]

i mean compiler optimization is kinda fickle isn't it

maybe it does in specific cases?

[scenic wraith]

You’re probably right

[vestal arch]

you'll probably get better answers in the c# server or something

They are identical, at least with an auto-backing field: https://sharplab.io/#v2:C4LghgzgtgPgAgJgIwFgBQcDMACR2DC2A3utmdgA4BOAlgG5jACm2NAdsJVQPYXHYBzJsADc2CMLEBfUuWr1GLdpwBmNJgBsAJiNlk9uHHAAs2ALIAKAJTED5Lr2wBebEl1p79tZq3PX7+xk0KSA

Stopwatch isn't reliable for micro-benchmarks

also debug and release builds are different

[scenic wraith]

Ah, in this case it’s not an auto backing field. But it is just a getter and setter to an explicit backing field.

Thanks for this info. Is there a better tool to use than Stopwatch for testing something like this?

[quartz folio]

Very different results with .net framework and mono though

[scenic wraith]

Looks like I need to learn more about benchmarking code

[thin aurora]

What happens if you apply MethodImpl(MethodImplOptions.AggressiveInlining)?

[scenic wraith]

Sadly, zero change

At least with my silly Stopwatch testing approach.

[thin aurora]

I imagine it's a nanosecond difference

Negligible at best

[scenic wraith]

Between a field and property?

[thin aurora]

Yes

Unless you did something wrong

Even calling a function takes no time at all. Especially aggressive inlining considering it gets rid of it altogether (AFAIK - not sure)

[scenic wraith]

Must be a testing methodology issue. :/ I’m literally getting more that a 4x slowdown with a property.

Testing approach:

• just a float variable, with a property that has getters and setters to that same float.

• first test: iterating 100,000,000 times over a line that just assigns the float.

• second test (in a separate run): doing the same thing, but assigning the property.

Assigning the field: ~972ms
Assigning the property: ~4200ms

[cosmic rain]

What build are you testing in?

[scenic wraith]

Hard to figure out how JIT, cache misses, or the GC could be interfering with the results. But I hadn’t accounted for:

• the difference between editor/debug/release build timing.
• the difference between .Net and Mono

Editor - probably stupidly

[cosmic rain]

Debug, Development, release?

[cosmic rain]

Probably.

oh thanks

[quaint crypt]

Hello,

I am using unity 6000 and terrain trees and infinite terrain.
I want to be able to add monobehaviors to my trees to be able to keep track of the tree's type, hp, state, make it fall, add rigidbody etc.

I know terrain tree's can't have monobehaviours, so what can I do?

My current thought is I need to have a tree manager that subscribes to OnTileGenerated, OnTileEnabled, OnTileDisabled and keep track of every tree instance based on location. I also need to switch terrain trees with prefab trees close to the player (5 meters - ish). Is this doable? WHat are better alternatives?

[steady moat]

No idea, but there is some API that suggest that you can get the Tree from the Terrain.
https://docs.unity3d.com/560/Documentation/ScriptReference/TreePrototype.html
https://docs.unity3d.com/ScriptReference/TreeInstance.html

[vapid vessel]

yeah you can get the instances: cs var trees = terrain.terrainData.treeInstances

which means you likely want some sort of "tree manager" per terrain. You'd keep track of all the treeInstances in a big list, you can get the position (0-1 a percentage of the terrain size, so some calculation needed to convert to world pos). From there, you can:

• loop through the list and use Physics.OverlapSphereNonAlloc at the tree position or similar for checking whether the player is near/chopping the tree down
• keep track of hp for each treeInstance
• spawn a "falling tree" prefab at the tree position when the hp is 0

[quaint crypt]

Can I efficiently remove a tree from the terrain using the API (without obvious stutters)?

[vapid vessel]

you'll need to make a new treeInstances array without the tree you want in it, which likely will have a bit of a stutter because it'll be a big array 🤔

you might be able to replace it with a tree that has zero scale though, which would mean replacing the one treeInstance instead of the whole array

which would be much faster

yeah it looks like you can do that - you'll want to test it though!

[quaint crypt]

So it seems that the key of a tree is its position (the link between a colider and the data associated with it).
I am also assuming since a tile can have 1000s of trees, it would be better to break a tile up into quadrants and only check trees that are in quadrants near a player?

[vapid vessel]

exactly, yeah 😁

you might even want to use a quadtree structure for it

[quaint crypt]

That sounds great, thanks!

I wonder how games like Valheim do it

[last quarry]

They don't use terrain trees. Or Unity terrain.

DOTS ECS would be my choice for such a large amount of interactable objects. It's not impossible with GameObjects but the engine will hate you.

[quaint crypt]

Thanks!@

[last quarry]

Valheim is also not the epitome of technology but it predates DOTS so we won't hold that against it 😏

It uses some type of voxel terrain. Trees, I think, are just GameObjects. It uses a low draw distance to get away with it all.

[night harness]

the ideal answer is probably never the one the game your thinking of uses 😛

[young yacht]

what is DOTS used for exactly?

[last quarry]

ECS is a replacement for GameObjects / components that handles large amounts of objects better

So when you're talking "infinite terrain with trees you can cut down", it starts to sound like an attractive solution

[cosmic rain]

Dots is not just ecs. Jobs system and burst compiler are all considered parts of dots and you can use these without ecs.

[last quarry]

True. Talking ECS here specifically

https://80.lv/articles/learn-how-this-unity-powered-rts-displays-thousands-of-entities-on-screen-at-the-same-time

[dense estuary]

For my game there will be a bunch of buildings throughoit the map. The player will enter these buildings (through a prompt on the door) and collect loot, then leave. There is going to be several large (premade) buildings.

How could I make so many buildings in one scene, or would I load a new scene. I'm not sure how I would transfer data about the player throughout scenes. Plus, if there are a bunch of these buildings, how do I save the scenes and .make new ones when the player leaves and goes into a building of the same structure?

I was thinking I might be able to somehow load the buildings under the map and teleport the player in. I might be able to load buildings, then when the player searches a building and leaves I could block off the door so I don't need to save it to storage.

But I don't know how practical that would be. Any advice?

[trim schooner]

ECS and subscenes would be a better/ modern way to do this

[dense estuary]

ECS?

[trim schooner]

Unity's entity system

google -> unity entities / unity sub scenes

you can load a sub scene pretty much instantly -> tele port in / out

[last quarry]

It'd be perfect for open world games if only it had a functioning terrain system like the one they canceled

[last quarry]

Depending on what's in them, are you quite sure you can't just brute force it?

Unity truly doesn't mind having 100,000 objects in memory

[night harness]

"large premade buildings" is a very unclear scale ye

[dense estuary]

My game is inspired by lethal company and repo. The buildings will be somewhat mansion sized and they won't be procedurally generated.

Wrong message to reply to mb.

[last quarry]

I get it

[night harness]

i have some pretty good experience with lethals dungeon generation 😄

[last quarry]

Do you mind if there's a hiccup / loading screen?

[night harness]

the game uses this plugin if your interested in learning more about that specific approach
https://assetstore.unity.com/packages/tools/level-design/dungen-15682

[trim schooner]

right, this sounds like just loading between different scenes and learning how to pass data around would be the better solution

[dense estuary]

I don't mind if there's a loading screen, no. Although my main goal for this project is immersion, "The Complex" level immersion.

[last quarry]

LoadLevelAdditive is probably a good bet.

[night harness]

how do I save the scenes and .make new ones when the player leaves and goes into a building of the same structure?

and they won't be procedurally generated.
little confused on what exactly you want saved here? the looting/exploration state?

[dense estuary]

There will be limited building types, but several of those types. So the player might stumble across one building, and find the same building with different loot at a different door.

Basically the positions of doors in the world is procedural, but the buildings appear more than once.

I'm not very good at explaining things.

There will be multiple instances of buildings.

But few types of buildings.

Does that make sense?

[dense estuary]

That seems super useful and I'm upset I didn't know about it sooner.

Thank you.

[dense estuary]

Also I'll look into this, it seems interesting.

Thank you

[dense estuary]

I currently pass settings data across the main menu and main scene using a class to store the settings and a class to save/load the settings in each scene.

But LoadLevelAdditive would make this process so much easier.

[night harness]

(For more comparable contexts, lethal uses additive loading where the ship is in a scene that never unloads and the moon is in a scene loaded and unloaded additively)

[vague cosmos]

Im working on making a fighting game right now, and im using Physics2D.OverlapBox to damage each collider after a attack is called, but once a collider is hit, the attack function is called ~20 times per second until the physics box is no longer overlapping. I'm having trouble figuring out why this is, would it be possible to get some help?

[last quarry]

Oh

[vague cosmos]

Not through unity, but is that what I should learn to do right now?

[last quarry]

Yeah that'd be your best bet at making sense of that.

Cleaning up the code would also help

[vague cosmos]

Sounds good

[night harness]

The FindWithTag at the start of update is also pretty rough

[vague cosmos]

Most of it is commented because I’m figuring out the best place to put everything by the way

[vestal arch]

there's also a lot of repeated code here

seems like a few dicts would help

or perhaps a list of your lists

[tall coral]

Hey, so I've been working on a procedural chunk generation script. Currently, it uses wave function collapse with a few randomly placed water and grass chunks to generate the land mass and water mass, then finds any grass bordering water and replaces it with beach. I'm now trying to think of strategies to spawn forest chunks, and I'm wondering what kind of generation techniques are usually used for this. I've considered choosing a random grass block, spawning forest, moving in a random direction until it finds grass, then replace that, go back to the root chunk, repeat until a random amount of trees have been spawned for that forest. This causes issues however if the total number of trees it tries to spawn is less than the total landmass it's on, it fails. So I considered creating a list of all grass chunks that don't border a beach, then randomly changing half into forest but I feel like it would look too chaotic. Am I on the right track here?

I should mention this was the previous version which used just one generation cycle with adjacency rules to spawn water, grass beach and forest chunks but as much as it is more dynamic, it's not very realistic / doesn't make much logical sense

[last quarry]

Hmm, bit of perlin noise as a first step maybe?

[delicate ravine]

what is the best way to check if an object is visible by the camera?

Renderer.isVisible can give true even if it is not in view i believe

[vestal arch]

visible period, or more specific checks like within the frustrum or has line of sight to the camera

[delicate ravine]

in sight, like if player is playing, they can see it

WorldToViewportPoint and the check if it is within bound?

[hexed pecan]

You have if (sprinting = true) at line 178. You want == to compare instead. = will set sprinting to true

[vestal arch]

well that wouldn't check if it was behind anything or not

you could use that along with a raycast to if there's something in the way, i guess?

actually no that would just check for a specific part being visible or not

[delicate ravine]

i dont care if it is behind something, just should be within the rectangle of the camera

in my game it cannot be behind things anyways

[vital jackal]

When i click on a scriptable object, is there a way i can get a callback for when that scriptable object is shown in the inspector? Or even when it is hidden (ie: something else is selected)

[fiery steeple]

Hey,
Why do I have a null reference exception even tho my tiles 2D array contains something please ? 🤔

[eager tundra]

it contains a null value 😄

[steady bobcat]

😐

[fiery steeple]

how ?

[somber nacelle]

the tiles array itself may not be null, but it contains null elements because it's filled with whatever is the default for the type when initialized and the default for a reference type is, of course, null

[fiery steeple]

is there a way to check if there's a null value in that array without looping on all of them or is it mendatory to loop on all of them and check first if they're null ?

[somber nacelle]

you don't have to loop separately, just null check it right there in your loop you already have and create an instance if one does not exist already

[steady bobcat]

var thing = myArray[x, y];
if(thing != null)
{
    //Do stuff
}

[fiery steeple]

The instantiation is done in another method but I see, thanks 👍 🙂

[steady bobcat]

If its not a monobehaviour you can also do: array[x,y]?.DoThingy();

but in this instance id not recommend that if this confused you

[somber nacelle]

in this specific case though that isn't useful because you can't use the null conditional operator on the left side of the assignment operator until c# 14

[fiery steeple]

wait what ? Why does it work only with "Monobehaviours" ?

[steady bobcat]

It does NOT WORK with monobehaviours

[fiery steeple]

I doesn't, I'm familiar with that syntax 🙂

[steady bobcat]

? is not safe to use with unity objects because of unity weirdness relating to doing == null comparisons

[somber nacelle]

here's why it does not work with UnityEngine.Objects https://unity.huh.how/unity-null

[fiery steeple]

So it's a bug or it's intended ?

[vestal arch]

for stuff deriving UnityEntity.Object, == null and is null are different.
you usually want == null.
the ?. syntax uses is null, so it's not that it doesn't work, it just works differently and is most likely not what you want

[steady bobcat]

just dont use ? right now 😆

[fiery steeple]

It feels like the IsValid() method in unreal where it checks both if the reference is not null and not in the process of being destroyed

[steady bobcat]

Yea its similar but its too late to change things

stick with

var thing = myArray[x, y];
if(thing != null)
{
    //Do stuff
}

[fiery steeple]

late for unity ?

[steady bobcat]

i think its too late to change. You could only really replace == null safely with an extension method that checks for null and valid state.

[fiery steeple]

they should add an IsValid() method because it makes more sense than what there's currently 😬

[vestal arch]

there is also just a bool cast/conversion

[eager tundra]

Rider nowadays recommends checking for "Unity null" with the bool conversion instead

[fiery steeple]

does this seem good ?

[vestal arch]

why would this run before your initialization anyways

that seems like something you should look into

[fiery steeple]

Yeah

Thank you guys 👍

[fiery steeple]

Tell me more

[eager tundra]

same as you did there

[steady bobcat]

the double access will probably be optimised away but tis a tad lazy

[somber nacelle]

is it actually recommending that? or is it just not giving the same warning that it gives for the explicit == null check? because the implicit cast to bool does do the exact same thing, and they have previously admit in the past that they overlooked that when making their analyzer

[vestal arch]

x != null and x in conditions are equivalent - same for x == null and !x
for any x that derives UnityEngine.Object

[fiery steeple]

wait what, isn't x equivalent to x != null rather ? 🤔

[vestal arch]

yes, i messed that up

[fiery steeple]

phew 😄

[eager tundra]

not sure fully I understood what you said, but it's recommending to use the bool cast for explicit check

either that or use is null if I'm not checking for "Unity null"

[vestal arch]

a bool check is not explicit, no

if anything it's more implicit

the actually explicit checks are either private or internal, unfortunately

[somber nacelle]

ah, looks like they finally updated their suggestions there. and they suggest the implicit cast to bool because it shows intent to check the lifetime of the UnityEngine.Object rather than the possible intention of a pure null check

[eager tundra]

I don't really like this suggestion too much either, but it is the only way to make the check explicit

[plush laurel]

I'm working in a game with a similar mining-building mechanic to that of terraria. I have a Tile struct and a custom grid class and I'm trying to think of the best way to store different types of blocks which will have different textures, different break resistance, different things they might do on place... What would you recommend?

[lean sail]

data like the textures or break resistance are pretty easy to store on scriptable objects. different things to do on place you could code through inheritance or composition, whatever way you find fits your flow better.

[plush laurel]

Thanks, what would be the best way to have a looot of block types, though? I think having a inherited class for each block seems inefficient and scales pretty bad, I don't know, maybe it's how other games do it?

[vestal arch]

definitely not separate classes, no

[radiant flicker]

Good afternoon everyone! I'm trying to get a character to look at specific objects in a scene. Right now I'm just trying to get the function working in general. I managed to get the normal rotation working but now I want to clamp the X and Y(?) axis to prevent the rotation from looking unnatural and I'm at a loss of how to approach this.

Here is how my code is set up. There are no references to other scripts.
https://paste.mod.gg/hvtmxbhcmesz/0

[lean sail]

thinking of terraria, i dont think you need an inherited class for each block type at all. The inheritance or composition would only apply when you need different functionality. Been awhile since i played so i dont remember exactly what blocks are there, but iirc you can toggle stuff like switches? That would be different functionality.

if you just had 2 blocks where the functionality is the exact same, whatever the base block can do, the only difference being the texture, the only difference would be creating 2 SO assets and providing different textures.

[radiant flicker]

Overview of my steps are:

1. Get a Transform reference to the head.
2. Store the initial rotation values (this is for later when I want the character to rotate it's head back to it's original position once it hits it's rotation limit.)
3. gain direct access to the head's x and y, rotation value so I can use the mathf.Clamp function limit the rotation.
4. Put that information back into my head reference and use Slerp to have it gradually look at a target.

What currently happens is that it...kinda doesn't work. It looks towards the initial target object but vibrates and place.

[lean sail]

have you tried using the IK package? Im pretty sure this is already built in

or sorry it mightve been "animation rigging"

[radiant flicker]

I have! Bone Rigging right? I was testing this out with a downloaded asset but...I think the OP did not correctly orient the animation skeleton from Blender to Unity so when I tried multi-aim constraints it just has a broken neck and I don't know what combination of up/forward vectors to use to get it to work properly.

So I figured it wouldn't hurt trying to do it the code way just to see. This is the asset pack in question https://assetstore.unity.com/packages/3d/characters/lowpoly-character-chibi-315595

If anyone has used it and knows what settings to put for the multi-aim I'm all ears but in the mean time I'm just using a simple 3D cube gameobject (with no rigging)

The end goal is to eventually have the character be able to look at anything under a specific list then after X amount of seconds it looks somewhere else. Like how Animal Crossing characters walk around in their homes.

[lyric veldt]

Does anyone know why my visual studio intellisense isnt working, I have tried everything, retarting my pc, reinstalling vs, restarting unity, reinstalling the unity package

[somber nacelle]

https://unity.huh.how/ide-configuration/visual-studio#if-you-are-experiencing-issues

[lyric veldt]

why tf was my Visual Studio Editor package deleted wtf

that fixed it thanks

[somber nacelle]

didn't you just say you reinstalled the package?

[lyric veldt]

I did

mutiple time

[somber nacelle]

then are you sure you didn't just forget to install it again after the last time you uninstalled it? that's really the only way i can see it having been deleted if you had been explicitly installing it multiple times

[lyric veldt]

I meant the package

in the

visual studio installer

[somber nacelle]

that's the workload

[lyric veldt]

oh

[lean sail]

Yea I think it was the multi aim constraint. I haven't tested around with it in some time but it should be customizable enough to make work as you want.
with your code, im not positive as to why its vibrating in place but it could be because of the headBone.rotation.eulerAngles part. When you read the rotation as euler angles, its converting it from the quaternion. The conversion could give you any set of euler angles that equal the same rotation

[radiant flicker]

Yea I think it was the multi aim constraint. I haven't tested around with it in some time but it should be customizable enough to make work as you want.

In this case the component worked fine ( I tested it out on some dummy gameobjects) the problem is the placeholder asset itself. I could techincally say "Yeah I know this works" and leave it broken for when I put the new stuff in but seeing it not work annoys me so here I am lol.

im not positive as to why its vibrating in place but it could be because of the headBone.rotation.eulerAngles part. When you read the rotation as euler angles, its converting it from the quaternion. The conversion could give you any set of euler angles that equal the same rotation

what do you suggest I replace it with? The reason I did that is because I'm trying to restrict how far the head can move left/right, up/down using mathF.Clamp

But everything I've searched for deals with active inputs and this character is just moving around autonomously. I feel like I'm close but I'm not familiar enough with rotations to know how to get the current rotation of an object the same way you would get the specific position. transform.rotation.x/y/z always turns up an error for me.

Okay I got the Slerp to work normally again.

But I need to test if the rotation limit is actually happening.

[lean sail]

i would probably start with comparing where the character is facing and the direction to the object to get the angle. Like through Vector3.Angle or even just compare the quaternions with Quaternion.Angle.
theres a few quaternion methods you could probably use like Quaternion.RotateTowards or AngleAxis to construct the final desired rotation

reading euler angles here at any point will be questionable

[radiant flicker]

I'll see what AngleAxis does. I already have the code working that it looks towards a specific object. What I'm trying to do is have it not turn pass a min/max angle limitation.

[rigid island]

where is the code question ?

[jagged path]

There is no channel for animator help

[rigid island]

[jagged path]

oh

ok

[tall coral]

With a 2d chunk map, what kind of pathfinding algorithm would be used to find, for example, all grass blocks in one land mass? The idea is to figure out how many grass blocks there are per land mass so that I can make sure the forest generation doesn't try to replace more grass blocks with forest than there even are available to change

Interaction.onInteract = new UnityEvent();
Interaction.onInteract.AddListener(() =>
{
    Logger.LogInfo("interacted!");
});
Interaction.onInteract.Invoke();

For some reason, this doesnt log

I know that Interaction.onInteract is a valid unityevent slot

[steady bobcat]

if the unity event is serialized it already has a value

otherwise, dont use a unity event (and use a real event instead)

[lean sail]

have you confirmed the code is actually running?

or that the logger itself works as you expect it to

[turbid pagoda]

Yes

I have put a log statement before and after and both run

[turbid pagoda]

Could you elaborate

[steady bobcat]

[SerializedField]
UnityEvent unityEvent;

^ this is given a value by unity, no need to = new();

public event Action MyCoolEvent; <- normal event

unity events replicate event functionality and allow serialized subscriptions but these are slow

[fiery steeple]

Hey, I have another question please :
For some reason my code colors properly the revealed tiles but not the not revealed tiles. So the code should :

• color the revealed tiles in BEIGE and LIGHT_BEIGE in a checker pattern [WORKS] ✅
• color the non revealed tiles in LIME and LIGHT_LIME in a checker pattern [DOES'NT WORK] ❌

[naive swallow]

You can get your answer by hovering over the underlined else

See what your IDE says about it

[fiery steeple]

it says the else is redundant but after removing it the issue remains

[lean sail]

the issue might be elsewhere then, not within these 3 lines of code. This should work as is

[somber nacelle]

yeah the issue could simply be that the colors dictionary has the same color for two of the keys

[naive swallow]

Ah, my bad I thought there was a return statement outside the brackets. You should probably use some logs or the debugger to find out what's happening here

[fiery steeple]

nope

[steady bobcat]

someone needs an enum

[fiery steeple]

for the keys ?

[steady bobcat]

yea

[tall coral]

Perfect, thank you

[somber nacelle]

can you stop posting screenshots of code? i'm sure by now you've seen how to correctly share your code dozens of times.

[fiery steeple]

but don't enums return an int value making the key work both with MyEnum.value and an int 1 ?

[fiery steeple]

my bad

[naive swallow]

So, if it's an even cell, you want it to be beige if revealed, otherwise red.
And if it's an odd cell, you want it to be light beige if revealed, otherwise lime.

It looks like the "Red" isn't working, so either that color is wrong, or it's never both even and unrevealed. Try some logs to see

[steady bobcat]

er no, you can cast enums to and from int but thats explicit

[somber nacelle]

enums are backed by an int and can be cast to and from them, yes. but there is no implicit cast

[naive swallow]

You'd need to cast it, but yeah, if you wanted to

[steady bobcat]

the council has spoken

[fiery steeple]

my bad not red, I put red for the test just to see if I was blind with colors or not, but the proper colors should be LIME and LIGHT_LIME

(for unrevealed ones)

[vestal arch]

just a sidenote, you should group by isRevealed first rather than the parity

[turbid pagoda]

Well but that should print shouldnt it?

[lean sail]

from those 3 lines alone and if Logger works as expected, i believe it should. thats why i say the issue might be elsewhere.
like whats the context here, where are you running this code?

[turbid pagoda]

Its not steralized

[fiery steeple]

why ?

[steady bobcat]

then it can have children!

use event instead

you can use Action to define one easily:
public event Action event1;
public event Action<int, string> eventWithArgs;

[turbid pagoda]

I cant change the code for defining the event

[lean sail]

while i also prefer to use c# events, its not like UnityEvent is impossible to use here. the performance aspect really doesnt matter

[steady bobcat]

if its not serialized there isnt a good reason to use it

if its on a monobehaviour/scriptable object and serialized then it has some benefit

I personally avoid them where possible as i dislike how hard it can be to check subscribers later

[turbid pagoda]

Interaction is a instance of the class interactable, which holds a definition for a unsteralized public UnityEvent (onInteract)

And I cannot change that

[steady bobcat]

then wack who designed it and stop setting it to a new instance?

[turbid pagoda]

But its not set to a instance

I cant add a listener to null

[steady bobcat]

its not a monobehaviour or SO ?

[lean sail]

the only thing id suggest to check around is if you new onInteract or set it to null at any point. the basic idea of newing a unity event, adding a listener, and invoking the event works.

[steady bobcat]

im puzzled at what this thing is

[turbid pagoda]

Its a plugin

[steady bobcat]

can you say what?

its confusing to me as i presume the plugin object invokes the event but why would they not even give it a value on construction?

[turbid pagoda]

They do

In the editor

[vestal arch]

just for better grouping - LIME beside LIGHT_LIME, BEIGE beside LIGHT_BEIGE

[steady bobcat]

wha

[turbid pagoda]

As a persistent event

[steady bobcat]

in the inspector?

[turbid pagoda]

What

[steady bobcat]

you said "in the editor"

[turbid pagoda]

Yes

The unity editor

[steady bobcat]

so it is serialized 😐

[lean sail]

🤷‍♂️ if you both wanna focus on the plugin or c# event/unity event thats fine but none of this is actually solving your problem.

[steady bobcat]

im trying to figure out what they are doing wrong

[turbid pagoda]

Is it steralized?

I might have been mistaken

[steady bobcat]

if you can see a GUI thing for it in the editor YES

thus you should not do = new() as you may break functionality

[turbid pagoda]

All I know is that the events for other instances of the Interactable class are assigned in the editor

[lean sail]

whats wrong is that we aren't looking at the context surrounding the object. it literally doesnt matter if its serialized if all that code is running sequentially. Which is why im trying to get context surrounding the code

[turbid pagoda]

Its a plugin

Through bepinex

[lean sail]

ah so a mod?

[turbid pagoda]

Yes

[lean sail]

we dont help with modding

#📖┃code-of-conduct

[steady bobcat]

i want my time back

[turbid pagoda]

But its still a unity problem though

[naive swallow]

Shame.

[long bison]

are you like modding a game or have modded unity?

[turbid pagoda]

Cmon nobody responds in the bepinex server this is like my last hope

[turbid pagoda]

A game

[long bison]

very interesting rule...

[naive swallow]

Welp.

[long bison]

so I finished coding my very small college project and when I went to build the game, I got this error for the script I've pasted to this message:
"The type or namespace name 'ShaderKeywordFilter' does not exist in the namespace 'UnityEditor'"

I searched up a solution for this and it told me to put "#if UNITY_EDITOR" at the very top of my program and "#endif" at the bottom of the "using" section at the top of the program. This didn't seem to fix anything, since I now get another error when I go to build, which is the following:
"The type or namespace name 'MonoBehaviour' could not be found (are you missing a using directive or an assembly reference?)"

Do you know how I can fix this? I am completely lost https://hastebin.com/share/ugezikejab.csharp

[steady bobcat]

you want to do this instead:

#if UNITY_EDITOR
using UnityEditor.ShaderKeywordFilter;
#endif
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[long bison]

oh

[steady bobcat]

and also surround your editor only code

[somber nacelle]

just remove the preprocessor directives and line 4, you don't appear to be using that namespace anywhere anyway

[naive swallow]

What you've done here is make your entire using block only exist in the editor. So when you build, UnityEngine no longer exists

[long bison]

oops, I probably misread that solution, I'll try it now

[naive swallow]

I think box has the idea. You're not even using that namespace anywhere. Just remove it

[long bison]

alright, those lines automatically put themselves there when I made the script so I had no idea if I needed them or not

[somber nacelle]

that one would not have been added automatically when creating the script. you probably auto completed something and either weren't paying attention to the namespace it said it was using (and therefore it added the incorrect namespace) or later removed whatever was using that namespace

[fiery steeple]

I logged and I have 50 that should be LIME and 50 that should be LIGHT_LIME so it doesn't make sense why everything has the same color 🤔

public Color GetTileColor(int i, int j, bool isRevealed)
{
    //print($"[{i}][{j} - {isRevealed} - {(i + j) % 2 == 0}]");
    if (isRevealed) {
        if ((i + j) % 2 == 0) {
            return colors["LIGHT_BEIGE"];
        }

        return colors["BEIGE"];
    }
    else {
        if ((i + j) % 2 == 0) {
            print("Light_Lime");
            return colors["LIGHT_LIME"];
        }
        print("Lime");
        return colors["LIME"];
    }
}

[somber nacelle]

log the actual color too

[naive swallow]

Well, then either colors["LIGHT_LIME"] isn't what you think it is, or something else is recoloring it after this runs

[fiery steeple]

I could switch it to red just to be sure

[long bison]

maybe it was OnGUI? Wait no, I think I remember accidentally autofilling something. Anyway, it seems like it's building successfully, thank you guys!

[fiery steeple]

like print(colors["LIGHT_LIME"]); ?

[somber nacelle]

sure, or maybe add more than just a single piece of data per log

[fiery steeple]

where in my code ?

[somber nacelle]

where do you think

[fiery steeple]

at the top of that method ?

no wait

I can't do that

so I have to put a print in each place where I return that color

public Color GetTileColor(int i, int j, bool isRevealed)
{
    //print($"[{i}][{j} - {isRevealed} - {(i + j) % 2 == 0}]");
    if (isRevealed) {
        if ((i + j) % 2 == 0) {
            print(colors["LIGHT_BEIGE"]);
            return colors["LIGHT_BEIGE"];
        }
        print(colors["BEIGE"]);
        return colors["BEIGE"];
    }
    else {
        if ((i + j) % 2 == 0) {
            print(colors["RED"]);
            return colors["RED"];
        }
        print(colors["LIME"]);
        return colors["LIME"];
    }
}

[somber nacelle]

so you've now confirmed that it is in fact returning a 50/50 mix of two separate colors which clearly indicates the issue is elsewhere

[naive swallow]

Okay, so then these are returning the correct colors. That means most likely something else is changing them after the fact

[somber nacelle]

but again, you should print more information in your logs. instead of a single cryptic piece of data you can include that data as part of a string containing more context

[fiery steeple]

I don't understand what that means and what other infos to print 🤔

I suspect this method as the culprit :

private void OnMouseDown()
{
    if (Revealed) return;

    // Make the first tile never be a mine
    if (!firstClick) {
        firstClick = true;
        if (Value == -1) {
            Value = 0;
        }
        OnFirstTileClicked?.Invoke();
    }
    
    Revealed = true;
    spriteRenderer.color = GetTileColor(Coords.x, Coords.y, Revealed);
    textComp.color = GetTextColor(Value);
    textComp.enabled = true;
}

[somber nacelle]

i'm not saying you need to print more info here now since we've already determined this is not the issue. i'm just saying you should provide more context in your logs just in general so instead of just seeing random pieces of data in your console and then needing to already know what that data is supposed to be, you can instead provide words and other context

[naive swallow]

Literally everything. Whenever you have to print stuff, print absolutely everything you can so you don't need to go back in and add more later

Your new best friend: https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/tokens/interpolated

[fiery steeple]

But I promise you here I don't see what else should I print 🥲

that's why I'm kinda confused 😄

[naive swallow]

Yes, now you're fine. But it took like three iterations to get all the info

If you had printed the object, the indices, the isRevealed, and the color all at once you could have saved yourself a bunch of reloads

[fiery steeple]

oh ok 😄

[fiery steeple]

So could the issue be here as I don't know if that method is called every frame or not 😬 ☝️

[somber nacelle]

did you know that you can look at the docs to find that out? https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnMouseDown.html

[fiery steeple]

Ok so I think that's not the culprit anymore

https://paste.mod.gg/xbvuzcpciqcg/0 here's the full code

[tall coral]

I think they mean stuff like $"color chosen for cell at {cell location} is now {color chosen}" so that you know what that color is coming from

[vestal arch]

why do you reset before generating

this is unrelated to the current issue, but that's exactly what i meant here #archived-code-general message

[fiery steeple]

Because later I want to have a reset button but without opening the scene again

[vestal arch]

that doesn't matter

i'm talking about what you have right now in StartGame

anyways, the issue is you never set the color when you generate the tiles

in GameManager:166, you just get the color, you never actually do anything with the color

[somber nacelle]

Okay now show us where you use the return value from GetTileColor

[fiery steeple]

nowhere

[somber nacelle]

so what does that tell you?

[fiery steeple]

I have to use it, I'm doing that right now, thanks 👍

Let's go 😄

[vestal arch]

anyways, about this - think about what StartGame does

it's saying to reset the grid before you even create it

[fiery steeple]

as I said it's there once we finished the first game, that's why I added that first condition to make sure "tiles" isn't null before executing the code below. But I think this will still create an issue as you (or someone else) explained to me above where "tiles" could be not null but the values in it are null 🤔

[vestal arch]

that literally just is not a concern right now

[somber nacelle]

there's also literally 0 reason to call ResetGrid in StartGame considering it only does something that GenerateGrid already does

[vestal arch]

you can call just ResetGrid and not GenerateGrid when you restart

you're trying to think ahead but you're skipping all the logical steps lmao

[fiery steeple]

But the instantiation happens in GenerateGrid

I know why I made that mistake

[vestal arch]

and do you need to instantiate all the tiles again if you don't reload the scene?

they all still exist

[fiery steeple]

because at first I thought about destroying all the tiles in the grid and instantiating new ones when the game restarts

[vestal arch]

the entire point of not reloading the scene is to avoid having to generate new tiles, no?

[vestal arch]

even then you wouldn't have a Reset before you generate

[fiery steeple]

Yeah, but I'm thinking about giving the player the choice to change the grid size between games, so in that case I will need to clear the tiles and instantiate new ones to the new grid size

[fiery steeple]

yeah

[vestal arch]

and you can call generategrid then, not every time you restart

[vestal arch]

you're stuck in this right now lol

[fiery steeple]

yes that's my main issue that I have in everything in my life 😄

[vestal arch]

yeah you need to slow down and actually think through these systems

[fiery steeple]

my brain can't do that 🤣

my brain is already thinking about creating the next Windows 🤣

[fiery steeple]

Why is there these black / dark lines around each square plz ? 🤔

[vestal arch]

what sprite are you using? the 2d elements square?

[fiery steeple]

I imported an image square

[vestal arch]

does it have a border

[fiery steeple]

it looks like yeah

is there an already made white square in unity directly ?

[vestal arch]

if you have the 2d feature, yeah

[fiery steeple]

2D feature ? What's that ?

[vestal arch]

did you create your project with the 2d template?

[fiery steeple]

I don't remember 😬

[vestal arch]

if so, you'll have the 2d feature installed
you can check in the package manager

2D Sprite specifically comes with some sprites

[fiery steeple]

It says "unlock" 🤔

[vestal arch]

since it's not in Assets, you'll have to click the "hidden" eye thing then search for "square"

[vestal arch]

...ok? that's in a button

not sure what you're expecting

[fiery steeple]

thanks, that's working 😄

[fiery steeple]

I'm confused on why it's "locked"

[vestal arch]

it's part of the 2D feature

[delicate ravine]

can you change the position of gameobject with NavMeshAgent with transform.position? I have an object which goes to another object and when it is near, it should go inside the other object, I am doing agent.isStopped = true before that, but transform.position is not changing the position

[rigid island]

you have to disable it first iirc

or there are methods to use

[drifting zealot]

You can but there are some scenarios in which you could have issues, for that reason the NavMeshAgent have a warp method that allows you to move the agent in a "correct" way

[rigid island]

ah yeah thats the method I forgot about..Warp
https://docs.unity3d.com/6000.1/Documentation/ScriptReference/AI.NavMeshAgent.Warp.html

[drifting zealot]

Hello guys, I have a question about properties and herency, Please check the following code:

This is being overriden in a child class with the following code:

it works but something is telling me that this is a bad practice, basically if I forgot the "base" in my set method I could cause an infinite loop, what do you think?

is this a common practice? or am I writing poor code?

[mossy snow]

poor code imo. Your property doesn't look like it has side effects, but it does for subclasses. It would be better to make it a private field and expose a public method to change it explicitly, which would then be specialized by subclasses if needed. What does your parent class do with this property? The fact that subclasses are implementing logic when its value changes and the parent apparently does not is smelly

[delicate ravine]

even wrap does the same

i am not update the position anywhere else in the code

[drifting zealot]

Basically the parent class contains the basics fields and methods that a controller/player must have(move, jump, grab something, etc), Then I have two child classes that works in a different way since the two controllers are a different, one is for VR and the other one for non-VR, the non-VR controller was written by me so is checking the field to do some action, but the VR (The one from the image) uses a few components that were not written by me, those components are checking their own variables so I need to modify their own variables using my own variable , in this way I can make my field affect those other scripts, What I try to do is not to have to modify variables from those other scripts in a different way; this way, by simply modifying a field in my code, I can change what is needed in those third-party components.I hope this is clear.

[delicate ravine]

foudn the issue, the other object is not part of mesh. so I had to disable agent and then use transform.position, and now it works

[mossy snow]

It took you a paragraph to explain a half-dozen lines of code, so no I wouldn't say it's clear. You cannot edit this common class at all? I don't see any reason you can't refactor this to be nicer. But you don't need to change anything if you don't want to

[naive swallow]

Might be better as abstract instead of virtual. Then every child class would be forced to make its own backing field, so you still keep the polymorphism but don't have a chance at a stack overflow

[proper pier]

If I find myself in need of an abstract static field, which C# does not support, am I better off manually adding a static field to each child class or using a "template instance" to replicate that kind of behavior

[lean sail]

what are you even trying to do with an "abstract static field" in the first place?

[proper pier]

something like string StateName = "dash"; would be nice to be static because it represents the name of the state associated with this class and it doesnt chane per instance

and itd be abstract because the parent class would force each child to implement it

[lean sail]

this whole setup seems pretty bad. How do you plan to reference a derived class by Type in the first place to access a static value when your setup is using an abstract class. You should likely be using that abstract class in every case possible.
Just make a regular abstract method that returns a string if you really want

[proper pier]

im not sure i understand your question. I have an abstract MovementCommand parent class and then for example a derived SlideCommand class. If I wanted to access some static field from the dervied class, why couldn't I?

[lean sail]

Its less of a question and more of a point. you'd have to actually reference the SlideCommand.Something field. There's no point of using inheritance if you're going to be manually handling logic for each derived class

Anything that handles commands should do it purely through MovementCommand

[proper pier]

yeah your right in general, but sometimes there are things you specifically would have to do manually. For example, state trees

which are internal to the system itself

[lean sail]

I dont know what youre specifically referring to as a state tree, but no you dont have to do it manually. That's literally the point of inheritance.

[mossy snow]

I'm with bawsi, your architecture makes no sense

[lean sail]

Either way just an abstract method returning a string already solves your issue

You cant have an abstract static thing

[proper pier]

got it; trying to learn tho; when you say manually do you mean like manually writing code for each derrived class instead of using the parent class

[lean sail]

this is what i mean https://dotnetfiddle.net/OLBxxR

plus also you'd be hiding objects if using static which just isnt a good idea

[proper pier]

Thank you for taking time to write that for me. I def understand your point now, although weren't you assuming that i was going to need the static field for some kind of polymorphic thing?

Perhaps this is just bad design, but in this class I have, in the BuildStateTree() method, it would be useful to have a static reference to the state name of other movement commands instead of having to manually inject the correct string name: https://hastebin.com/share/jidexezoqu.csharp

[lean sail]

you cant use abstract on it so there is no polymorphism on it. static fields belong to the type

[proper pier]

I get why you cant technically have them but I don't neccessarily get why they imply bad design

[mossy snow]

Something is creating these commands based on the constructor, and that thing knows what all the commands are. Why isn't that thing building the state tree? It has the knowledge of what they are and that's probably a better place to describe how the states are supposed to interact with each other

[lean sail]

im not entirely sure what im looking at with this state tree tbh so im not sure what these values are even being used for.

[proper pier]

good point. I was thinking it might be good to just have each movement command describes its own "state capabilites" for encapsulation sake though?

[mossy snow]

You mean convenience? You have tightly (and in a brittle way by using magic strings) coupled states together this way

why use a magic string at all? You could be referencing the types directly

[proper pier]

yeah i def could i dont know what i was thinkin

However, I don't see the issue with tightly coupling states with their command. To elaborate a little, the BuildStateTree() method is creating a DAG that evaluates whether or not the movementCommand can be executed based on current state. Anyways I think I get your points so don't feel like you need to continue this convo unless you want to (if u have more to say and want to I'd love to hear it)

[mossy snow]

There isn't anything necessarily wrong with doing things that way (personal style), but since the states are already tightly coupled, you don't really need magic strings here.You're doing something similar for the transition key. Why isn't that an enum, for example? You actually have a comment to explain what the values mean instead of just making the values tell you what they are

[proper pier]

Your right, I've actually been meaning to do that I just haven't gotten around to it: a bit of cleanup is due. My novice logic for tightly coupling the state logic to the command itself is just that I'm pretty sure the state logic wont have to change at all at runtime so why not "build it in". I think that makes sense, anyways.

Thanks for the help guys

[velvet fossil]

quick question anyone knows web tools or extensions for creating UML diagrams from my code?

[cold parrot]

Rider has a built in feature for that. Generally those end up so complex that they are effectively useless.

This also can convert/generate from c# and is an allround great tool for UML et al https://staruml.io/

[velvet fossil]

Thanks so much, I'll check it out

[young yacht]

bool HasLineOfSight()
    {
        Vector3 origin = transform.position + Vector3.up * 1.5f;
        Vector3 direction = transform.forward;

        if (Physics.Raycast(origin, direction, out RaycastHit hit, 100f, wallMask))
        {
            return false;
        }

        return true;
    }

hey guys how would i go about checking if there's a wall between the enemy and the player then go around that wall?

[true heart]

you probably need to have the walls in a layerMask, and check if the raycast hits that laymusk then return nothing, else return true

[young yacht]

exactly what i did

fixed it already

added 4 emptyGameobjects around my player

enemy chooses one, goes there tries to shoot, if cant hit then choose another random one, repeat

[swift falcon]

Instead of that, You can get a direction by subtracting two positions.

var direction = (Enemy.position - Player.position)

This would be the of the Raycast, which allows you to check for walls more efficiently.
Unless I am misinterpreting your questions/statements

[young yacht]

i want the enemy to feel a bit smarter than just "walk straight towards player"

since the enemy can shoot with a pistol, dodge and run away

[swift falcon]

Well that's for the eyesight of the enemy.

And for walking behaviors, you can use NavMesh for the pathfinding, which means finding the shortest path to the destination without running into obstacles. (Unity handles that for you if you use their built-in NavMesh)
And to actually figure out the destinations your enemy should choose, there's no single way, it depends on what you want

A good starting point for some simple logic is by setting the destination to the player, and then offsetting it with a large Random.insideUnitSphere , this would make the enemy approach the player seemingly indirectly.

[young yacht]

i already got some logic going so its harder to make this raycast work

i'll probably add a coroutine to my HasLineOfSight()

[swift falcon]

I might be able to help you improve it if you send the script

[young yacht]

its quite big

[swift falcon]

You can use a website

[young yacht]

which one was it again?

[vapid vessel]

I use https://paste.myst.rs

Yeah something like that, theres a lot of them

Goddamn, I recommend splitting it into multiple scripts because there's too much unrelated logic in there.
I don't completely know where to start to be honest with you

[young yacht]

yeaaaa

my workflow is to vomit code first

then separate it when the enemy is behaving well

[swift falcon]

Its gonna be faster to seperate it from the beginning

[young yacht]

also its easier if you actually see it in game

Hello everyone, im currently facing an issue for my Fade in Fade out script I made, each time the player presses E a fade in fade out anim plays out and switches the player from normal to his combat varient
everytime I click E the player just stands still and my movement doesn't work and he doesn't switch to his combat variant
The error im getting:

NullReferenceException: Object reference not set to an instance of an object
PlayerInventory+<PlaySwordCutscene>d__5.MoveNext () (at Assets/Scripts/PlayerInventory.cs:28)
UnityEngine.SetupCoroutine.InvokeMoveNext (System.Collections.IEnumerator enumerator, System.IntPtr returnValueAddress) (at <bc88c87c01184d1499d92d3b79a10ce6>:0)

And here are the 3 scripts I used(The Sword Pickup, Player Inventory and CutsceneFade): https://paste.mod.gg/hudraoorcybu/0, https://paste.mod.gg/kramgwerzivm/0, https://paste.mod.gg/gagdusapzhou/0

[vestal arch]

playerWithoutSword doesn't have a PlayerCombat component.

line 28 is playerWithoutSword.GetComponent<PlayerCombat>().inputEnabled = false;
there's 2 things that could be null there, playerWithoutSword and playerWithoutSword.GetComponent<PlayerCombat>().
if playerWithoutSword were null, it'd error on line 27, so it's the latter

[grizzled dune]

I fixed it, thanks for the help
turns out I didn't realise that I gave playerWithoutSword both the combat and movement scripts when it was only supposed to get the movement part only

[vestal arch]

do they need to be separated though?

could just have them be the same object that switches modes and sprites and such

[grizzled dune]

eh I wrote all that code, i won't put it to waste for now
I may update it later on

[fiery steeple]

Hey,
For my Minesweeper game, I need to figure out all the adjacent "0" tiles and the adjacent "0" to those tiles, etc...
How can I do it ? I'm thinking about the floodfill algorithm, but is it the right approach or is there a better way please ? 🙂

[vestal arch]

sure, that one works

[fiery steeple]

but is it the best way ?

[vestal arch]

there's no "best"

this one works fine

[rigid island]

thats usually what is used no?

i think the original used floodfill

[fiery steeple]

I have no clue, that's why I'm asking 🙂

[naive swallow]

I'm thinking about the floodfill algorithm, but is it the right approach or is there a better way please ?
Is there a problem with flood fill?

[fiery steeple]

nope, just asking if there's a better way 😄

/ is that the conventional way

[naive swallow]

What problem with flood fill are you looking to improve upon

what could be made better

[fiery steeple]

🤷‍♂️

[naive swallow]

so then just use it

you have a problem, you have an algorithm that solves that problem. End of consideration.

[fiery steeple]

I have this tendency of overcomplexificating things, that's why I always ask 😄

[vestal arch]

this question is part of that tendency

[fiery steeple]

yes

[vestal arch]

floodfill is pretty basic, it's just depth-first search except you aren't searching for anything

[naive swallow]

Okay, so, here's the situation: I have a whole bunch of royalty free vehicle meshes from a bunch of different sources, so there's a whole bunch of different ways they're constructed. Some of them have every individual submesh as a separate GameObject, some of them are a single GameObject with a dozen materials.

What I need to do is to recolor certain materials with a "Team" color. Currently, I have a script on the parent of the meshes that has a list of Renderers to recolor to the team colors, and it goes to each renderer and loops through its materials, changing the _BaseColor of the material to tint it to the team.

The problem with that is the ones where it's a single renderer with multiple materials. Some of these materials need to be tinted, but some don't. Imagine a vehicle where the chassis, hood, and windows are all sub-meshes on the same renderer with their own materials. I want to tint the chassis and hood, but not the windows.

I'm expecting to put a script on all of these renderer objects to determine which materials to tint, but what would be the best way to do that? If I have another component and drag in materials, they're going to be different instances than the ones the mesh uses when it's spawned in, so I can't just loop through those and change the color. Should I just make a list of "Excluded materials" and loop through the renderers materials, and skip the ones that share a name? That feels kinda... code-smelly. I hate using the name of something for a functional purpose.

[night harness]

I've gone through the exact same bullshit before and it def is code smelly. I ended up having a water tower turn blue cuz of it's name 😛

Depending on what you need and dont need to mess with, any chance you could identify the type of material and/or shader properties?

eg. you could figure out what "glass" is

[naive swallow]

For the most part, I'm just letting every mesh keep its materials however they are and just kinda eyeballing which ones need to change. I suppose I could try to make a sort of unifying shader they all share and having a property on that one for "Team-Tintable"

[late lion]

I can think of two options:

1. Make it index based. Each material corresponds to a specific submesh, which has a specific index.
2. Store a property on the materials you want to change. Such as a _UsesTeamColor integer property which is set to 1. It will be ignored by the shader since it has no corresponding property, but it will still be saved on the material and can be fetched with Material.HasInteger or Material.GetInteger.

As long as the original material has it, it will get duplicated to instantiated copies. To add the property to the material, you either have to do it from editor script, Material.SetInteger, or use the Debug inspector mode to edit the property list directly.

[naive swallow]

Can I just... add a property to an arbitrary material?

I... never even considered that as an option...

[late lion]

Yes, it's just a serialized key-value pair list.

[naive swallow]

That's so simple

I just never thought of it

[late lion]

There's also Material.SetOverrideTag and Material.GetTag, but I haven't used it for custom tags and that's not really its purpose, but it might work.

[delicate ravine]

unity doesnt consider parent class of a script class as the component of an object?

i have a parent class that implements common stuff and then 2 child classes that are used by different objects. but if i try to get the parent class using getcomponent it doesnt return it

[night harness]

classes don't have parents or children, that's something the Transform class specifically deals with. do you mean inheritance?

[delicate ravine]

nvm the issue was something else. i was talking about inheritance

[naive swallow]

You'd probably need to show some code. How you're defining the inheritance and how your attempting to get the component

[delicate ravine]

i figured out the issue, i was accidently using a child class in the GetComponent instead of the parent, hence it was returning null

[neon mason]

Hey

[vestal arch]

inheritance commonly does use parent/child terminology though?

[vestal arch]

[neon mason]

Where is the Unity 6 app binary exe?

[vestal arch]

• downloads are available on the website
• you should use the hub to install stuff instead though, rather than downloading the editor directly
• not a code question, this would be more appropriate in #💻┃unity-talk

[neon mason]

I see it generated the exe after putting a new folder, however it didnt generate it in the existing folder where Unity generated files lay

[somber nacelle]

are you referring to your build exe? because that goes into the folder you tell it to

[neon mason]

Yes, however it did not generate it. It only worked with a clean build folder

[somber nacelle]

well this is still not a code issue so if you need further help then take it to #💻┃unity-talk and actually provide details instead of expecting people to immediately know wtf you are talking about

[low spear]

Hi, we're getting this error when starting Unity suddenly. We can't isolate it to a specific change, and it's not saying what file it is... it's just this message. Any ideas how to get more information? Has any got this recently?
Parser Failure at line 2: Expected closing '}'

[final kestrel]

yeah same here, it's not your fault no wrry bro

[low spear]

Yeah, just found the messages from others getting it

[final kestrel]

same lol, 1 hour fighting against nothing

[low spear]

same same... what a waste of time that was 😄

[leaden ice]

I think it's probably related to the cloud outage

[final kestrel]

yeah, cause can't create more project related to cloud

Honestly that is new to me, apologies.

I've just started using the Newtonsoft.Json package and parsing a json file via TextAsset and also having this issue. I was pretty sure I somehow parse the json in a wrong way, but maybe that's not the case.

I'm seeing HitObj receiving the result from GetRaycastObject(). How exactly do I get that object from the Raycast and pass it to HitObj?

[somber nacelle]

How exactly do I get that object from the Raycast and pass it to HitObj
what do you mean by that? HitObj is the object hit by the raycast because that is what you return in the GetRaycastObject method

#🤖┃ai-navigation

[dusk apex]

You're already doing so. If you're getting null instead, it's because your raycast in the method that you made did not hit anything and returned null as you've told it to do so.

[tawdry zinc]

hey this is more so a general question rather than a coding specific one

but is there any way for me to change the colour theme for visual studio to github dark default?

I have this theme installed for visual studio code (blue one) but not visual studio, and when I search up downloads for visual studio, it only comes up with results for visual studio code

its not one of the default themes I looked through them all

[somber nacelle]

this is not unity related. nor is it code related.
but you can search the available extensions inside of visual studio

[tawdry zinc]

oh sorry

[somber nacelle]

if the theme exists it can be found there

[dense yoke]

so since the method returns hitbj gets what is returned?

[somber nacelle]

yes

[tall coral]

So, the concept for my 2D building system uses a grid-based system to place start and end points for walls, but then uses a spline to create a curve if the start and end point aren't in line with each other. What concept best fits this / what unity methods should I learn about in order to be able to accomplish this?

Here is a diagram of how it would work, green being start and end points and yellow being the center of the curve

[cosmic rain]

Bezier curves

[dense crow]

It looks like no one is using 'partial' in unity, Do u guys use it ?

[somber nacelle]

i use source generators, so yes i do create partial types.
whether people use them for defining types across multiple files is an entirely different story. it's really just a personal preference if you want to do that or not

[dense crow]

How should i name script files of a partial class ? I have InputManager that includes singleton logic and core logic

[somber nacelle]

use a convention that makes sense to you

[cosmic rain]

It sounds to me like these should be separate classes then. Or use the unity singleton implementation.

Not partial classes.

[dense crow]

I don't get it, Managers should be applied singleton

public partial class InputManager
{
    private static InputManager instance;
    public static InputManager Instance
    {
        get {
            if (instance == null)
            {
            }
            return instance;
        }
    }

    private void Awake()
    {    
    }

    private void OnDestroy()
    {     
    }
}

[cosmic rain]

Inherit from a generic singleton class. Unity already implements one.

[somber nacelle]

wait does it really?

[dense crow]

I can't make it work, can u provide an example ?

[cosmic rain]

Hmm... Must be a fake memory. There's an editor ScriptableSingleton, but you can't use it at runtime indeed.

[cosmic rain]

You'll need a base generic class with generic static instance field. then inherit it with your manager and use it's type as a generic parameter.

Then put all the singleton related logic in that base class.

[dense crow]

I already have 1 and tested it a lots, it created many bugs so from now on i will only put static variables inside its class, AI also recommends to not using singleton inheritance

[tame thunder]

Typically when handling thousands (or at least a thousand) AIs in 3d space that, while don't need complex decision making, do need to be checking for hundreds of potential targets

Is something like DOTS practically required? Or are there solutions efficient enough to stick with the OG format

I understand using nav mesh agents is beyond impractical but even when you have to have non agent AI determine distance and targets when they're tightly bunched up
You lose grids/partitioning and it becomes a mess where 20,000 checks are ran on a single frame

[dense crow]

mono + job + burst+3d grid is quite enough in most cases

[night harness]

Considerations on if theres any potential checks you can re-use or avoid in certain contexts would assist heavily in bringing down whats necessary there too i'd imagine

[night harness]

If I have two tri’s (two sets of 3 world space positions) is there any suggested way on checking if they intersect?

[west lotus]

The best AI optimisation is understanding that your AI logic and decision making do not need to run every frame. For example in our fast paced fps game we run the complex utility functions once every 0.5 to a 1s depending on the type of brain. Data collection for potential targets and world state can be the same.

[tame thunder]

I would be running it every 3 seconds

[tame thunder]

Alright thanks, that gives me a bit more confidence

Because dots is well above my knowledge lol

[west lotus]

Every 3 frames for thousands of agents just means that every 3rd frame of your game would be heavy. What I’m suggesting is each agent having it’s own timer and update frequency based on realtime rather than frame count. That way each frame you are running ai logic for less agents

[tame thunder]

I can't use agents regardless as that's far too much performance hit

They're mostly just simple home made state machines that use local movement

[west lotus]

For example we also put our ai in a priority queue based on their engagement and proximity to the player

[tame thunder]

This would be top down

[west lotus]

Thats an agent in my terminology

I did not mean nav mesh agents

[tame thunder]

Ahh ok

[west lotus]

Any piece of software capable of “making a decision and acting on it” is an agent

Technically

[west lotus]

This for example means we prioritise updating the context and utility weights of enemies currently engaged in a firefight with the player rather than some dude 500 meters back behind 3 walls trying to path find.

That dude can wait

[tame thunder]

Do you have any suggestions on how to handle this when a large amount of agents are in big clumps?

[west lotus]

I would need more context for your game. What I shared as an example works for us because we are making an fps

You seem to be making an rts

What about the clumps is concerning you ?

[tame thunder]

Mount and blade would probably be the ideal example,

I handle it very messy at the moment but having the two "squads" that become interlocked (upwards of 40 agents each) run through each other's list of agents within the opposing squad to determine the closest unit

But that causes issues where if there are say a thousand agents, then we can have scenarios where 50,000 magnitude checks happen within seconds (obviously not ideal)

Because there's no restriction on a squad being say, in a single straight line and able to access every target in the scene

Or in tiny groups that don't typically need to run that many checks

At best I've split ranged up from melee so melee units only check the squad they're engaged with

[west lotus]

Well this sounds like some form of spatial partioning is needed

[tame thunder]

Do I just need to work on a much smaller partition?

I did try the partitioning originally but even with 2x2 unit grids (which created a lot of partitions) there can be a lot of units/agents on a single grid

I'm sure the system works but I've made a mistake with how I'm thinking it through somewhere

I did originally try to limit it to squads on squads but a player could just run a squad down the side of the line and the enemy naturally would just accept death lol

[west lotus]

Well at that point you can write a parallel job to do distance checks

[tame thunder]

Yea it's looking like Ill have to implement a proper job/burst system

[west lotus]

Or you could try sticking your units inside a kd tree. Thats very fast for finding X amount of closeset things to a point

But you will need to be smart about how and when you rebuild the tree

[tame thunder]

That would work even worse than spacial/grid partitioning if they all clumped into one big horde right?

But better for long range battles over larger maps?

[west lotus]

Mmno because you would use to find the closets units within a range

The range could be a meter

There is a jobified implementation inside the mega city repo somewhere in the audio or util section

[tame thunder]

But the range might need to be 1 meter or 100 meters so there would be a lot of worst-case checks I think

Oh ok cheers I'll have a look

[dense crow]

instead of running all each 3 seconds u can split it into many groups, and running groups on a queue in many updates, and just apply the result when u want

[tame thunder]

Oh yea I'm doing this already it's qued

Just that each check itself has a 3 second gap before it's requed

Hi, we're replacing the standard Windows cursor, with a sprite on a canvas (so we can do animated weapon aiming ones etc.). We hide the windows one with Cursor.visible = false;, but that also keeps it hidden if you move the cursor outside of the window etc. Is there a good way to detect that? Like the window losing focus etc.?

[trim schooner]

It's only hidden while Unity still has focus, make it lose focus and it will come back already

[zealous vortex]

uh why could there be a huge ass triangle in my mesh ;-;

it only apears when the size of the mesh reaches about 300x300

[mossy snow]

it likely has a 16 bit index buffer and exceeded 2^16-1 verts

[zealous vortex]

how would one go about avoid that but still having more vertices

[mossy snow]

set its index buffer format to 32 bits

[zealous vortex]

[visual fjord]

Hi

How can resolve this error

"Feature 'global using directive' is not available in C# 9.0. Please use language version 10.0 or greater."

[leaden ice]

delete the global using directive from your code on the line the error indicates

[visual fjord]

How?

[leaden ice]

With your keyboard

the delete or backspace key

[leaden ice]

looks like you're using some kind of code generating plugin'

and that plugin is generating those

Or you have some kind of setting in your VSCode that is automatically compiling the code

and making these Debug/net10 folders etc

basically this is probably a VSCode issue

you have it misconfigured somehow

[visual fjord]

How u can see misconfigured?

[leaden ice]

I can tell it's misconfigured because it's creating that obj/Debug/net10 folder and contents

[vestal arch]

because those obj files shouldn't exist

[visual fjord]

I get it

And yeah

I have delete the files

[old trout]

just kind of a sanity check, is there any real downside to waiting on a callback in a coroutine for a process i want to be functionally infinite? this is for a turn based prototype

[leaden ice]

One note - you almost definitely just want yield return null; not yield return new WaitForEndOfFrame()

[old trout]

any reason why?

(that line is actually only there since i was calling EndTurn in StartTurn to test this lol)

[leaden ice]

waiting one frame is yield return null
WaitForEndOfFrame is a special thing for waiting until a specific part of the frame used for some very niche post rendering things

check the docs

also creating those objects is unecessary GC allocation

[vestal arch]

Alright I'm pretty confused here. I found this script online because I want to find a nice way to serialize dictionaries.

using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class SerializableDictionary<K, V> : Dictionary<K, V>, ISerializationCallbackReceiver
{
    [SerializeField]
    private List<K> m_Keys = new List<K>();

    [SerializeField]
    private List<V> m_Values = new List<V>();

    public void OnBeforeSerialize()
    {
        m_Keys.Clear();
        m_Values.Clear();
        using Enumerator enumerator = GetEnumerator();
        while (enumerator.MoveNext())
        {
            KeyValuePair<K, V> current = enumerator.Current;
            m_Keys.Add(current.Key);
            m_Values.Add(current.Value);
        }
    }

    public void OnAfterDeserialize()
    {
        Clear();
        for (int i = 0; i < m_Keys.Count; i++)
        {
            Add(m_Keys[i], m_Values[i]);
        }

        m_Keys.Clear();
        m_Values.Clear();
    }
}

I expected 2 Lists to show up in the inspector.

but instead I got this

How... is that happening?
