Its 10:30 PM

I need to go to sleep

This is literally the last fix I need to make

If anyone has an idea what I can do pls lmk

I want to run the below code but after I changed Destroy(gameObject) to gameObject.SetActive(false) it works once, but then if I requip the item it doesnt work the second time or any time after that, its just frozen, equipped but the animation doesnt play and it doesnt heal which makes no sense

using UnityEngine;
using System.Collections;

public class EnergyBar : MonoBehaviour
{
    public int healthRestoreAmount = 10; // Amount of health restored
    public Animator EnergyBarAnimator;  // Animator for the energy bar
    private UserInventory userInventory;
    public GameObject playerInventoryGameObject;

    private bool isConsumed = false; // Prevent multiple uses

    void Update()
    {
        if (Input.GetMouseButtonDown(0) && !isConsumed) // Check for LMB click
        {
            Consume(FindObjectOfType<GameManager>());
        }
    }

    public void Consume(GameManager gameManager)
    {
        if (gameManager != null)
        {
            isConsumed = true; // Mark as consumed
            gameManager.health += healthRestoreAmount; // Increase health
            Debug.Log("Energy Bar consumed! Health: " + gameManager.health);

            if (EnergyBarAnimator != null)
            {
                EnergyBarAnimator.SetTrigger("Eat"); // Play the eat animation
                StartCoroutine(WaitForAnimationToFinish()); // Wait before destroying
            }
            else
            {

                gameObject.SetActive(false); // If no animator, destroy immediately
            }
        }
        else
        {
            Debug.LogWarning("GameManager not found!");
        }
    }

    private IEnumerator WaitForAnimationToFinish()
    {
        float animationLength = EnergyBarAnimator.GetCurrentAnimatorStateInfo(0).length;
        yield return new WaitForSeconds(animationLength); // Wait for animation to finish
        userInventory = playerInventoryGameObject.GetComponent<UserInventory>();
        userInventory.BarQty -= 1;
        Debug.Log("New Inventory: Flamethrowers=" + userInventory.FlameThrowerQty +
          " | Katanas=" + userInventory.KatanaQty +
          " | Bars=" + userInventory.BarQty);
        gameObject.SetActive(false); // Destroy after animation ends
    }
}

[modern creek]

where/how are you enabling the object again? if you setactive(false) it, you need to setactive(true) it to enable it

[leaden ice]

Also if you're deactivating this object or destroying it, this Update code is of course going to completely stop running

[steady bobcat]

As the others said, disabling the game object will stop update + fixed update + late update AND coroutines (current coroutines will end)

[rigid island]

then you're passing a null to it?

[quasi elbow]

I was never rly accessing it

[fiery elm]

my unity wont let me login

i click sign in, it pings back on the browser, and goes back to the hub

ik this becayde if i close unity and refresh the api page it reopens it

but it doesnt do anuthing and im still on the login page in UH

[trim schooner]

this is a code channel, and that is not a code question.. delete it all (so you don't get told off for cross posting ) and move to #💻┃unity-talk

[fiery elm]

fixed

[kind willow]

So I got a class for my saves, and I use clumsy web api to send out save files once something got changed
Question, is there a magical kind of way to call a method each time any value there getting changed?
The way I am doing it right know is converting fields onto properties where I call this method once it get changed, and still manually adding calling this method each time I use arrays of data because there is no way to do this property trick for array elements, right?
Is there anything better I could do?

[steady bobcat]

i hope you aren't doing a web request for every single var change. its better to make a set of changes and then update.
probably not sustainable to have this done automatically for each field

[kind willow]

I do not really respect the host and I am still within their limits

[steady bobcat]

respect? its just inefficient to be updating too frequently

[kind willow]

besides I am still doing it within a timer of 4 seconds and the savefile size is about 14 kilobytes

[kind willow]

and it's not my problem that it's ineffiecnt? the whole idea of making a webgl game is inefficient af

[steady bobcat]

if its only being sent every 4s then that sounds very reasonable. your first explanation made me think every write caused a web request

its your problem to make your game run well right? dont get mad at me 😆

[kind willow]

I am not mad

it's just host says no more than N requests in M seconds and size not more than K kilobytes

I can try to really optimize sized and delay saving insignificant or frequent chances but eh they can take it as it is

[kind willow]

yeah honestly I forgot about the timer because it's in a plugin for integration in one of those browser gaming sites

[terse surge]

okay so, i have a feature i wanna add but im not sure how i can add it, so im gonna use a display to describe how it works.

Cyan/blue = ground (has ground layer)
Green = player
Magenta = enemy
Gray circle = overlap circle of enemy for player detection
Red line = raycast to detect when enemy is too close to a wall/ground and needs to jump

what i want the enemy to do is when they get too close to a wall like that, to asses how tall of a jump it is as indicated in the image, and only call Jump() if the height is less than a certain amount. But how do i asses the height in such a situation? I am not using tile maps, the map will be drawn in one piece

[hexed pecan]

You could do a raycast starting from the above and front of the enemy, pointing downwards, to check the height

Or a more robust way is to do a multiple horizontal raycasts in front of the enemy, stacked vertically

Something like that

I did a similiar thing to find vault/climbing height in 3D

[terse surge]

ah so a raycast starting from player position.x, player position.y + heightCheckDistance, and if the raycast catches the ground, then its too high, otherwise, jump

[hexed pecan]

Might wanna use circlecasts though since raycasts can go through small holes

[cold parrot]

you could go the total opposite approach, put a line-collider on the vertical edge and annotate that with the jump-height information

[terse surge]

but we only wanna check in one direction, is raycats not bettert there?

[terse surge]

you mean like a line collider on the ground itself?

[hexed pecan]

I mean if you have gaps like this then you get false positives

[cold parrot]

i mean you put markup in the scene that informs your character controller instead of making a generic solution that analyzes any odd terrain

[hexed pecan]

I'd check if there's a couple of misses before considering it a proper gap

[cold parrot]

whichever is best, depends on the game's design

[hexed pecan]

Third option is a mix of these two: Bake the height/climb/jump positions after analyzing the map

[cold parrot]

fourth option: put "jump links" into the scene that enemies can follow like its ground.

[terse surge]

seems like a rather specific situaiton, but its also nice to be extra cautious, but wont circle casts over detect?

[cold parrot]

its always a balancing act

[terse surge]

i dont think im quite following

[cold parrot]

your main challenge with such problems is that you have to manage the complexity of all potential (edge)cases

and you have to think hard what the easiest option is for your specific design

the generic approach via raycasts is certainly flexible, but also complex. But when it works, its fantastic.

[hexed pecan]

Not sure what you mean "over detect". They have volume unlike raycasts. You are trying to detect where the enemy will fit, so the cast having some volume makse sense

[wintry crescent]

is there a difference in performance between UnityEngine.Mathf.Round and unity.mathematics.math.round?

it's negligible either way, but I'm curious

[terse surge]

oh so its like a raycast with thickness?

[hexed pecan]

Yepp

[terse surge]

hmmm i think i see what you mean, ill choose the raycast stuff system because, well, i understand its steps so hey, it works

anyways, thanks guys

[hexed pecan]

The most important parts are here

Raycast will work if your map geometry is simple enough 👍

[rapid glen]

Hey all, I'm hooking values from the settings menu in to gameplay. I'm not very experienced with FMOD as my co-worker set that stuff up, however I need to hook volume control in to it.

In settings i have audio values such as Master/Effects/Music Volume, which are values from 0-100. I'm assuming I'll need to divide value by 100 when setting applying it to FMOD volume level.

Is changing the volume as simple as doing EventInstance#setVolume and using the settings volume type i want it to inherit? for instance, for an effect,

instance_WooshEffect.setVolume(_effectVolume * _masterVolume)

Then the value of "Effect Volume" is scaled by "Master Volume", and applied to instance?

Finally, is 1 generally the highest value i should use when setting volume of an instance?

[quick token]

about to but,i just saw a for loop that was compiled as

for(; ; )
{

}

anyone know why it was compiled like this

[rapid glen]

i think that's basically while(true)

[quick token]

oh good point, it was in a coroutine so that would make sense.

[quick token]

btw, im pretty sure most FMOD questions are asked in #🔊┃audio (still haven't used it myself yet)

[rapid glen]

oh rip lol thanks. doing my own and if it doesnt work then ill re-ask over there. so many channels! didnt see it

[hexed pecan]

You can also use mixer channels and set their volume, or the master volume of the bus, instead of having to scale every event's volume by manually multiplying by masterVolume

[rapid glen]

that would be more ideal. im not sure how to reference the bus, or where it might be. what "type" is it?

[hexed pecan]

I think FMODUnity.RuntimeManager.GetBus("bus:/") gets the master bus

You can call setVolume on that

[rapid glen]

ok i will give that a try! thank you

[wide totem]

Im not sure where to ask this, so apologies if this is the wrong channel.
I recently switched to a Composite Collider 2D from a tilemap collider. This works perfectly fine, but the switch made me realise a bug that was happening from before. When an upwards force is applied to a object with physics above around 80, they seem to clip through the ground on return downwards. I failed to realise this before because the tilemap collider would push them back out, but the composite collider is made of outlines, so it cannot. I would provide a video, but I am unable to on this device.
(image 1 is height from ground, around 6-7 units, image two is example of them falling into the ground)

here is my collider details

[wide totem]

increasing the radius of the collider outline does help, but it does not solve the underline issue of the object temporarily clipping through at high(ish) velocities. Here was can see the object still temporarily clipping through the flore (this was a pain to take a screenshot of)

[soft shard]

If you plan to use casting of any kind, I would suggest checking out this repo to help visualize the different shapes (they basically do what Osmals graphic shows and can be used in addition, or as a replacement of the Physics calls): https://github.com/vertxxyz/Vertx.Debugging - I personally found it a big help in my own projects where I had to use casting of some kind

[terse surge]

yea i already use debug drawray but thanks

my jumping also works

[rapid glen]

i am told to use VCA, going to look in to that

[wintry crescent]

Any idea why OnMouseUpAsButton might not get called? I have colliders on my objects, they're on the default layer, all enabled and everything, proper size, I'm clicking on them and yet nothing. Does it perhaps not work with new input system?

[somber nacelle]

none of the OnMouseXXX methods work with the input system. use the event system interfaces for it instead

[wintry crescent]

I know it's not being invoked for sure, I have a debug on that function that never appears, I made sure the correct script is on the object etc etc

[wintry crescent]

ah

is there a very quick and simple replacement for this specific function?

or do I have to reimplement the whole functionality myself

[somber nacelle]

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/SupportedEvents.html

[wintry crescent]

cool! thanks!

sadly, OnPointerClick still doesn't work, and isn't called

[somber nacelle]

am i going to have to explain the entire setup for you or have you actually searched how to use those?

[wintry crescent]

dont worry I know what I'm doing

public class BlockController : MonoBehaviour, IPointerClickHandler
    {
      /// irrelevant code here

        public void OnPointerClick(PointerEventData eventData)
        {
            Debug.Log("AAAAAAAA");
        }
    }

I am admittedly new to the input system overall, but it does work elsewhere in the project

[somber nacelle]

great you know how to implement an interface. have you actually searched how to use the event system interfaces or am i going to need to explain the setup

this is also not an input system issue at the moment

[leaden ice]

You need the conditions in the scene to be correct as well

[wintry crescent]

okay, well, I suppose I don't know how those interfaces work exactly

I do have an event system in my scene

[leaden ice]

Do you have the appropriate raycaster in the appropriate place?
Do you have the appropriate other component(s) on the object?>

[somber nacelle]

do you have the relevant physics raycaster on the camera and a collider on the object?

[wintry crescent]

1. collider on the object, yes
2. raycaster I did not have, but I added one to my camera and it didn't improve the situation

[leaden ice]

what kind of raycaster

what kind of collider

which camera

[wintry crescent]

the only camera in the scene

[leaden ice]

and the collider is on the eame GameObject as the script with the IPointerEnterHandler?

[wintry crescent]

yes

[leaden ice]

Show event system inspector too

(the whole object)

[wintry crescent]

it's the default one

[leaden ice]

and show your console?

when you try to click

[wintry crescent]

nothing appears in console

when clicking or in general

[leaden ice]

one possibility is you have some other object blocking this object

perhaps a UI element

could be invisible

[wintry crescent]

no ui in this scene

no other colliders either

only a bunch of objects with the same collider/script combo

[leaden ice]

also make sure your code is saved and compiled

[wintry crescent]

it is

[leaden ice]

and try removing/re-adding the physics raycaster

[wintry crescent]

this project was originally set up for 2D, could that change things?

[somber nacelle]

no

[leaden ice]

not really but... check your Project Settings -> Physics settings

make sure PhysX is selected

(assuming you're using Unity 6)

like this

[wintry crescent]

oh that's funny

it was not selected

[leaden ice]

there ya go

[wintry crescent]

that sounds like the issue but I gotta restart the editor to know

[leaden ice]

that's a relatively recent one on the checklist 😢

Yeah it's very possible they disable PhysX by default in 2D projects now.

It would make sense

[wintry crescent]

nah, that's on me actually

changed it a while ago, forgot

[leaden ice]

ahhhh

The classic PEBKAC

[wintry crescent]

yup, works now!

thanks ;D

[remote cobalt]

These are two seperate tilemaps, and in my script i take an array of TileBase. The one with the higher index is rendering on top of the other, even when the actualy z is set to 0. Any ideas why ?

[leaden ice]

YOu answered it yourself no?

2D sorting is based on sorting layers and order in layer

[remote cobalt]

In what layer ?

The thing is each is its own tilemap

[leaden ice]

IDK. What did you mean by "the higher index"?

[remote cobalt]

I can show you

[leaden ice]

The tilemap has a Sorting Layer

that's what I mean by layer

[remote cobalt]

Is there any way i can screenshare you ?

[leaden ice]

make a thread and show screenshots

[remote cobalt]

These are two seperate tilemaps, and in

How would I go about hosting a website in my game
not like Hosting my WebGL game online, like... my game will host a local website

I've considered just getting some kind of Python engine into my game (IronPython maybe?) and then hosting is just one "py -m http.server" away
but Im sure its possible to do this nicer... right?

[quick token]

#🌐┃web

[magic tusk]

I think... technically it does fall under #🌐┃web
I should clarify, I want a Windows (or Mac I suppose) build to be hosting the local website, is there a relatively simple / easy way to do this somehow using Unity Engine / C#

[dense rock]

hey there, I want to make a text editor in unity similar to how notion works. Can I get some suggestions on how I could do that? I feel just a big inputField wouldn't quite do the job..

[leaden ice]

It's not really clear what you mean by this to be perfectly honest

What's the end user experience you're trying to create?

[magic tusk]

distribute webGL build to local network

[leaden ice]

Any off the shelf web server will do that

Nginx for example

A webgl build is just a static resource on a web page basically

[magic tusk]

Im not the smartest when it comes to web stuff, I assume it's made to be easy to use but I just can't seem to figure out how to make it work in Unity

[leaden ice]

You pretty much just dump the webgl build files into the serving directory for your web server

That's it

The webgl build comes with a serviceable index.html page

[magic tusk]

But I want the game itself to call / setup the web server, is that doable?

[leaden ice]

I don't really understand what that means

If the game is webgl it runs inside a web browser

A server has to be serving the game for the game to even run for webgl

[magic tusk]

there are two builds A is a windows build and B is a webGL build
A will host B
players can access B to interact with A

hope that clears it up

[leaden ice]

I mean you could just have your A build start a web server

With Process.Start

Alternatively

You actually do the serving of the html in C# but it seems weird

https://gist.github.com/define-private-public/d05bc52dd0bed1c4699d49e2737e80e7

For example like this

But it's pretty odd

Because you'd have to make both builds

And somehow distribute them together to the windows machine

I would probably just go with having the windows build start an off the shelf web server

And distribute that side by side with the windows build

[magic tusk]

right, I actually considered Process.Start
but to my understanding end user would also need whatever web hosting solution, so I wanted to avoid that
So I looked into C# hosting and it was rather odd

Im currently considering compiling for windows build and then dropping the webgl build inside the windows build lol

[leaden ice]

It's going to be way better than something you cobble together in c#

[leaden ice]

Yes you could find some small lightweight web server executable and bundle it with the windows build

Or find a C# solution

Either will work

But the separate process is likely better

[magic tusk]

who's making small lightweight web server executables in this economy 😭 (and where could one find tools like this)

[leaden ice]

GitHub

Another option is to actually use a real in the cloud website, like JackBox.tv does

[magic tusk]

I see, I'll probably go with some C# webhosting solution then

[leaden ice]

But the game won't be running entirely over LAN that way of course.

[magic tusk]

yeah I was afraid of the "other option" because of a mixture of cost, latency, and just uh... sunk cost fallacy?

but I think the web host thing is a funny way to go about doing this so I'd give it a shot

[latent latch]

I was trying to bum off bittorent trackers for a pseudo listening server, but turns out it's a pain in the arse to echo back and forth off it

AWS for 5 bucks a month is a pretty good deal if you need one

[elfin socket]

The documentation for Mesh is a bit confusing, how could I get the mesh in a format similar to this?c // Four vertices of a unit square in the x-y plane Vector3 vertices[4] = { {0.0f, 0.0f, 0.0f}, {1.0f, 0.0f, 0.0f}, {1.0f, 1.0f, 0.0f}, {0.0f, 1.0f, 0.0f} }; // Triangle indices use clockwise winding order Triangle triangles[2] = { {2, 1, 0}, {3, 2, 0} }; I thought for triangles I could use Mesh.GetTriangles() but that doesn't return a list of integer Vector3 but confusingly a list of just ints instead? vertices however makes perfect sense, I guess it'd just be Mesh.GetVertices().

[leaden ice]

Vector3[] verts = myMesh.vertices;
int[] tris = myMesh.triangles;```

yes the tris array is just ints

they are indices into the vertex array

[elfin socket]

Oh so the triplets simply aren't paired together?

[leaden ice]

yeah you just read it by threes.
0, 1, 2 are the first tirangle
3, 4, 5 are the second

and so on

[elfin socket]

Ohh, I see. I wonder why it's not just something like Vector3i or whatever that would be called in Unity

But thanks!

[leaden ice]

because this is simpler to blit around in memory

[elfin socket]

I see

[little cypress]

Hello all! Newbie here, been trying to build the essentials project to WEBGL but having issues with audio building

Basically everything is fine with the 3d audio in the play zone but when built to webgl it goes 2d and fixed volume

I have tried using some spatializer plugins like Resonance Audio without success, also haven't found the solution online

is it a known issue? I'm using the 6000.0.16f1 version for the project

[leaden ice]

#🔊┃audio

(also you should upgrade your Unity that's a quite old version)

[elfin socket]

So my plan is to just get all collisionmesh components from the scene, copy them into above data structure for steam audio. Then copy over Unitys global transform and use the resulting scene as reflection simulation input.
Does that make sense?

[little cypress]

I'll try that first then ask around over there, thanks!

[elfin socket]

And yes I know there is a steam audio plugin I could use instead, but in my case it'd be pretty hard to integrate.

[woven pendant]

hey, i have an active ragdoll I'm trying to balance, i need to try and figure out when to take a step, which foot and where the step needs to end. What's the best way i could do it? I've tried lifting the foot and placing the foot down when the velocity magnitude of the pelvis is over a threshold, and then placing the foot down at the current velocity of the pelvis as a position, (this is all happening on an animator which is located at 0 0 0) clearly that wasnt going to work. Any ideas?

[mossy flare]

Try emailing Boston Dynamics?

You are asking about an engineering problem that's on the boundary of human knowledge

lol

Most active ragdoll systems fake it by adding an upwards force at the pelvis to straighten the character

[cosmic rain]

They might also be interpolating between physics and an animation.

[woven pendant]

Mmmmmm good idea

[mossy flare]

https://www.youtube.com/watch?v=HF-cp6yW3Iw

You have seen this?

It describes the fake force I mentioned

Hello! I am having issues with this Interaction Code I wrote. It works, yes. But it makes the Camera Movement too Choppy and makes it feel really weird. Any idea why? Would appreciate some help, thank you in advance!
This is my code: https://hastebin.com/share/avecajopeg.csharp

||The code is not really long, but I didn't want to fill up chat ||

[hexed pecan]

I don't see anything related to camera movement here

[mossy valley]

Camera Movement is here: https://hastebin.com/share/wokopohaqo.csharp

[hexed pecan]

Try again 😄

[mossy valley]

I moved it to LateUpdate and it works a bit better now. It doesn't happen often but still happens here and there.

Ohh

Wait wrong script

[mossy valley]

https://hastebin.com/share/ixidenuhan.csharp

THIS SHOULD BE IT

Hopefully

I moved "HandleMouseLook" from Update to LateUpdate just now.

[hexed pecan]

Okay so you have this common mistake: cs float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime; float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;

Mouse input should not be multiplied by deltaTime, it makes it inconsistent

So remove that multiplication. After that you need to lower your mouseSensitivity by around 50x to 100x

1-2 is a common value I think. In that ballpark anyway

[mossy valley]

Okay, so just removing it is fine?

[hexed pecan]

No, read the other part of my message

[mossy valley]

Okay will try, brb!

Yes, will reduce the sens too!

[mossy valley]

Lmao, it fixed it! And it feels way smoother! Thank you so much <3

[hexed pecan]

Np, do you mind linking the tutorial you used for this?

Just curious if it's one of the usual two tutorials that spread this mistake

[mossy valley]

I didn't use any tutorial, I wrote the code myself 😓

[hexed pecan]

Alright, did you use a bit of ChatGPT for that mouse part?

I know that it likes to make that mistake

[mossy valley]

Yeah I did

[trim schooner]

is this AI code?

[clever shadow]

lol no

oh maybe a mix, because of the comments?

[trim schooner]

because it's doing weird things and has comments for everything

[clever shadow]

thats my full function, i am loading the fbx at runtime and instantiating it

there is one comment in there from the AI, "// Assuming you have a default state in your AnimatorController named "DefaultState""... the rest is mine

[trim schooner]

That's even more odd

animator.Play("DynamicFBXLoad"); this string has to match something in the animator

[clever shadow]

ya it does

in the animator controller

[trim schooner]

that's the default state, you dont need to tell it to play that

[clever shadow]

i am a beginner with unity, can you assist me?

should i just delete that state

[trim schooner]

no, why would you do that? 😄

does it have an animation clip assigned

[clever shadow]

oh you mean animator.Play();

just do this?

no it doesnt

not in the editor

// Override it with the first animation clip
                    OverrideController["DynamicFBXLoad"] = clips[0];```

this is what im doing at runtime

I load the clips from the fbx file

[trim schooner]

so, at run time... does that work? Does it have an animation clip assigned after this has ran

[clever shadow]

no it's not working. i can see the motion field remains empty

[trim schooner]

ok, what's clips[0] does that have an animation assigned?

[clever shadow]

AnimationClip[] clips = Resources.LoadAll<AnimationClip>(fbxPath);

i can see in the debugger it is loading the clip correctly

[trim schooner]

OverrideController["DynamicFBXLoad"] = clips[0];
// #1
                    // Assign the override controller to the animator
animator.runtimeAnimatorController = OverrideController;
#2```

You need to put 2 logs in, at #1 and #2 and see if the clips are being assigned in #1 nad in #2 see if the runtime anim controller has been updated with the relevant data

[clever shadow]

which field should i examine for 1 and 2?

[trim schooner]

you'll need to work that out, I don't know these api's without looking it all up

You're trying to determine if the clips and controller are assigned and if not, at which point it fails

[clever shadow]

k thank you!

[placid edge]

if I call a coroutine like this, how can i pass a variable by it considering all coroutines involved have one?

[cold parrot]

You would use the "proper" way to start a coroutine: get an Enumerator and run it.

public void Start () {
    IEnumerator enumerator = Foo ( 10 );
    StartCoroutine ( enumerator );
}

private IEnumerator Foo ( int count ) {
    for ( int i = 0; i < count; i++ ) {
        yield return null;
    }
}

alternatively (and very much not recommended)

StartCoroutine ( "Foo", 10 );

[leaden ice]

Just don't call it that way.

[languid hound]

Just curious why is the alternative not recommended?

I use that albeit it's sparingly used for transitions anyways

[leaden ice]

The string version is error prone as you get no compile time validation that your method name actually exists

It's also slower

and in this case, generates garbage

[somber nacelle]

the string version also relies on reflection and therefore has more limitations and a slight performance impact (if using it a lot). one example of a limitation is you cannot use local methods for coroutines

[cold parrot]

most of all, using the string API "because it makes things easier" pushes you down a path of very bad code design

[leaden ice]

Let's say you refactor your code and rename the Totemxxx methods. This call will fail the next time you run the game. Wouldn't it be nice if the compiler cought that immediately?

[languid hound]

Oh crap yeah that makes a lot of sense rip

[cold parrot]

to be fair, Rider can refactor that now 😉

[languid hound]

It's a shame rider doesn't have some free commercial license like VS does

I would make the switch in an instant

[cold parrot]

VS doesnt either

[languid hound]

What hold on

Could you elaborate sorry my crappy signal won't load google

I was under the impression I could release a commercial game with VS

[leaden ice]

VS community is not for commercial use

[languid hound]

Maybe my definition of commercial is botched

[leaden ice]

nvm I'm wrong

there are revenue thresholds though

I think 1 million USD

[somber nacelle]

well vs's commercial license is a lot more lenient than rider's is. rider requires purchasing a license if you work on anything that is commercial, even if it is not making money. vs only requires purchasing a license after a certain revenue threshold and/or team size threshold

[leaden ice]

yeah it'd be nice if Rider had a similar non-zero free tier

[steady bobcat]

i remember when visual studio was only a paid product 🧓

[craggy veldt]

there's a chance they will replace vstudio with vscode

[somber nacelle]

lol no there isn't

[naive swallow]

Not even slightly

they're entirely different products for different purposes

[cold parrot]

1 million is the hard cut off, otherwise only 5 users in your org are allowed to use it commercially for non FOSS.

[steady bobcat]

yea no way

[craggy veldt]

i said there's a chance 🙂
vscode uses the same internal as vstudio ever since devkit was a thing

[steady bobcat]

then why is the vs code debugger so shit with native code

[somber nacelle]

there is 0 chance that microsoft will drop vs in favor of vs code. vs code doesn't make them any money

[craggy veldt]

incase y'all don't know, vstudio still uses the old net Framework.4

there's a long discussion regarding this on c# server incase y'all interested

[cold parrot]

one thing to be aware of: Microsoft captures your with very friendly and cheap offerings for small business and entry level use. After which they make it very difficult, almost impossible for you to leave. Mostly because you've budgeted and organized around microsofts platform that cannot be replaced incrementally without massive separation/integration pains.

what might seem like a good deal at the start will cost you dearly later. The adivce usually goes: you either buy everything from Microsoft or nothing.

[craggy veldt]

as in being developed in net Framework.4
you can do new net stuff ofcourse, it's just the editor being built/developed based on ancient framework

[steady bobcat]

Maybe they can replace it with an electron app! /S

It's actually scary how many things in windows now don't even use their UI anymore but web views

Apple makes better programs for windows than Microsoft

Okay maybe only Apple music...

[cold parrot]

this is all optimized to be "easier to sell to (clueless) management"

[craggy veldt]

lemme say it again.... Devkit on vscode uses the same internal as VStudio 😌
you can even see the same background services as vstudio when you run vscode + devkit

[cold parrot]

to be fair, they made their own electron cause electron was shit

[fiery elm]

you installed a shit debugger

a dm one works flawlessly

bps, stack traces, debug console, all that jazz

var lookup

[steady bobcat]

Dm one? This is mostly when i'm trying to debug rust

I use vs for cpp otherwise

[craggy veldt]

there's a chance... the 1 sign is they killed MacOs support last year....

[somber nacelle]

visual studio for mac was a completely different program as well, it was just a rebranded xamarin studio

[craggy veldt]

no.. it was worse... it's MonoDevelop

not even joking

😄

[steady bobcat]

who remembers the lil box in monodevelop that would say stuff

[somber nacelle]

they're the same thing

[craggy veldt]

they're? oh

[somber nacelle]

https://en.wikipedia.org/wiki/MonoDevelop

MonoDevelop (also known as Xamarin Studio)

[craggy veldt]

but yeah I'd consider that as a sign or at least an effort to drive their users there to use VSCode..
also vscode is crossplat... while vstudio isnt 🙂

aight im done promoting vscode... not even being paid by msft 😄

[steady bobcat]

They keep adding stuff to vs, unreal got some good features not long ago too. I think it won't go anywhere (I hope)

[somber nacelle]

i wouldn't consider the discontinuation of vs for mac to be any indicator that they are dropping support for vs on windows any time soon. it's more likely they just didn't want to spend resources developing a completely separate IDE that was only being used on a single platform that also wasn't a large share of the usage. windows is by far the biggest desktop platform and visual studio has a huge market share for .net development (at least compared to vs code). microsoft also actually makes money from vs licenses which simply do not exist on vs code (what with that being completely free)

[craggy veldt]

yeah fair

[steady bobcat]

I guess Mac users have xcode? (I pray for them)
Maybe they are working on a re write for VS as it's been a few years since a major release?

[daring cove]

Hey,

A simple question.

I'm rotating a radar dish that has a fixed angle where it can see targets.

In this example the radar is scanning a 70 degree section of sky in 0.1 seconds.
This is done to calculate the optimized traverse rate to scan the sky so that it doesn't miss anything.

float radarHorizontalAngle = 70f;
float radarScanTime = 0.1f;
float radarTimeToScanSky = (360f / radarHorizontalAngle) * radarScanTime;
float radarTraverseRate = 360f / radarTimeToScanSky;

Now I need to offset the forward vector of the radar by the radarTraverseRate to get a constant 360 rotation to scan for targets at an optimized rate.

Vector3 forward = radarTurretMotorDrive.transform.forward;
forward.y = 0f;
forward.Normalize();

Vector3 heading = forward;

// how to offset the heading with radarTraverseRate??

radarMotorDrive.TargetHeading = Vector3.SignedAngle(Vector3.forward, heading, Vector3.up);

Basically I'm asking how to offset a vector by an angle?

[cold parrot]

on mac, everyone uses jetbrains

vs for mac was also only monodevelop reskinned

[vestal arch]

i use vscode on mac

i think nav does too? don't remember

[hexed pecan]

Basically I'm asking how to offset a vector by an angle?
You can construct a quaternion and then multiply the vector with that. Quaternion * Vector3 rotates the vector

[cold parrot]

probably everybody uses VS Code in some form

[steady bobcat]

ah ye i forget about jetbrains products

[cold parrot]

if you do JS webdev, and anything that doesn't have a jetbrains IDE, the VSCode is strong, not so much for 'real apps'

[hexed pecan]

@daring cove And you can get the Quaternion with, for example, Quaternion.Euler(0, yAngle, 0) (not sure what kind of rotation you exactly want)

[rigid island]

ye

[swift falcon]

does anyone know why my vs doesnt read my code?

[naive swallow]

I'm so sorry

[steady bobcat]

WPF and WinForm still stuck using parallels / vmware fusion win11

[daring cove]

Hey thanks for the response.

I want the radar to yaw so offset the heading vector by the offset of radarTraverseRate.

[hexed pecan]

My example should work then since yaw is the Y angle in unity

[daring cove]

error CS0019: Operator '*' cannot be applied to operands of type 'Vector3' and 'Quaternion'

heading *= Quaternion.Euler(0f, radarTraverseRate, 0f);

[steady bobcat]

its quat * vec

[hexed pecan]

That translates to heading = heading * quaternion

Yeah you need to flip it

[daring cove]

thats weird

[hexed pecan]

Similiarly a -= b translates to a = a - b so not that weird

[leaden ice]

Heading = quaternion * heading will work

[somber nacelle]

while typically multiplication in math is commutative (meaning you can flip the multiplication order and get the same result), multiplying quaternions and vectors is a bit different so it is only defined in a specific order within the code

[craggy veldt]

in this case it just Unity quats don't have implicit operator for multiply with the vector on the left side

[vestal arch]

multiplication is only commutative if it's defined to be, like for the reals and the complex numbers
it's not commutative for, say, matrices or vectors or quaternions

[naive swallow]

🖐️ Vectors! 🖐️

They be weird like that

[daring cove]

Okay, now the target heading is being calculated weirdly.
It is wrapping around 180 so its slowing down the traverse. Making the traverse slower in a sinusoidal pattern in respect with 180 degrees.
The traverse rate is 700deg/s

The turret is calculating the direction to rotate with the offset from its current heading and the target heading
and computing the duration to fire the motor for.
But in this case the offset is only 20 degrees so it's traversing extremely slowly.

[shadow wagon]

how could i turn a basic black/white texture into a mesh? idk if this is the right channel but I cant see a geometry specific one

[daring cove]

I might be approaching this problem in the wrong way...

[hexed pecan]

Toss the related code in a paste site, easier to help that way

[shadow wagon]

Anikki, problem is google keeps serving me results that arent even relevant

[hexed pecan]

How accurate does it need to be?

What's the use case?

[daring cove]

Sounds like a ridiculously difficult problem

[hexed pecan]

Most solutions probably turn it into a grid graph first

[shadow wagon]

not too accurate, i basically just want to draw a few different map shapes for a level, and when i enter a room, I pick a texture and then generate the floor from that

like these could be used to make 3 different levels

[hexed pecan]

Marching squares can also be useful here

Just need to post process it a lot if you want the result to be as simple as your first example

[steady bobcat]

if its pre made stuff... just make the mesh to start 😆

[shadow wagon]

i only made the first example geometric looking as it was too annoying to draw it as the triangle representation to illustrate the point

[hexed pecan]

Yeah do these exist before the game starts?

[daring cove]

you could probably just sample the texture with a certain resolution and just 1 = vertex, 0 = empty

[hexed pecan]

Unity has some built in stuff for generating polygons for sprites, perhaps some of that tech is exposed

[shadow wagon]

for now they do, but the plan later on is to generate them when you enter the dungeon

[hexed pecan]

That's a starting point, you then have to fill it with triangles

[cold parrot]

process: make a poly-line trace of the edge, triangulate the enclosed area.

[daring cove]

then run edge detection to get the corners and smooth them out
this way you could get a pretty nice quad topography across
The run a greedy mesher over it to get max area topography

[shadow wagon]

marching cubes looks like it could work nicely

[cold parrot]

you make a poly-line-trace by performing an edge walk

[hexed pecan]

Marching cubes is the 3D variant of marching squares

[shadow wagon]

oh yeah i meant squares

[cold parrot]

marching squares makes no sense here

but the edge walk part of it would help

starting points for more googling
tracing: https://en.wikipedia.org/wiki/Boundary_tracing
triangulation: https://en.wikipedia.org/wiki/Polygon_triangulation

[hexed pecan]

Marching squares is used to turn grid/texture data into meshes all the time

It would make it easier to handle inner/nested polygons too

The tradeoff is having to probably discard a lot of the work (triangles)

[cold parrot]

idk in what way marching squares would help here, maybe you would have to explain, it certainly isn' the shortest path to the initial picture in the question

[hexed pecan]

"Not the shortest path" is not the same as "makes no sense"

I'm just providing an option

[daring cove]

Maybe following a terrain generation tutorial would help.
Treating the image as an heightmap and making the zeros holes
maybe even as high walls

[shadow wagon]

what if i was to do it with a tilemap instead? I still want to have an actual mesh for the environment, but tiles seem easier to work with then using textures

just use the tilemap to create a rough idea of the level, then create an actual mesh with the grass tiles

like that

[hexed pecan]

You can get results like these with marching squares

[daring cove]

beautiful

[hexed pecan]

You can always post process (for example, mesh relaxation) it to adjust the shape

[shadow wagon]

thats pretty close to what i've imagined

[hexed pecan]

oh! i remember seeing these ages ago

[chrome marsh]

Just a simple question
i have vehicles in my physics based game, and at the moment, there is a slight issue regarding colliders.
i want vehicles to have concave insides so that objects can move inside of them, not accurately but roughly, this is fine
However im not sure wether to

1. Create a gazillion box colliders for each concave mesh so that objects can move inside of them and interact physically (roughly 20 or more colliders per complex mesh, this would make me redo alot of my code)
   or
2. Seperate the vehicle parts into a gazillion more vehicle parts so that there are no more concave meshes and i can just apply convex colliders to all parts (roughly 50 or more parts, this also would make me redo alot of my code)

I want to go with the most performance friendly solution, but i also dont want to spend a lot of hours just manually creating colliders for each vehicle

[unkempt cobalt]

you mean like during runtime? or just trying to make something

o nvm yea what osmal said

[lean sail]

whats making you need to have meshes for 20 or 50 parts? the performance friendly way to me would be like making box colliders for each side of the car.

regardless of what you do though, i don't think you'll really get the result you want from just colliders and rigidbody. An object inside your car, meaning an object within a bunch of colliders, won't move as we do in real life. The car will move and the object will hit the back of the car probably causing pretty drastic collisions

[chrome marsh]

ig the 20 or 50 parts dont need mesh colliders and they can survive using other types of colliders, fn they are mesh colliders because i dont have to tweak those manually.
Also second option is something i tried and gave up half way because of how time consuming it was

[lean sail]

I still dont see why you even need colliders for up to 50 parts

[chrome marsh]

that is not a problem as i know how to code so that objects dont move by themselves inside of the car and stay relative to it, i think

[lean sail]

I would definitely set up as much as you can using box colliders and consider which objects dont actually need colliders. Like im sure the user isn't gonna freak out when the object doesnt bounce against the rear view mirror

[chrome marsh]

I need all doors to be openable, the chair, pedals and panel are seperate because they can be destroyed, and every single time a concave mesh area appears, i need to split that part into 4 or more pieces so that it doesnt make the collision too inaccurate

[chrome marsh]

thats a good point, pedals and steeringwheel probably shouldnt have colliders, but the inside of the car and chair must have those

[hexed pecan]

Use primitives where possible and mesh colliders where absolutely needed

Most of that looks box-able to me

[chrome marsh]

is there no way to automate primitive collider placement?
My main problem rn is that its way too time consuming
If theres no wrokaround for spending time thats fine

This is the one i tried making manually, and i think ill go with that because having 50+ objects in a single car is true that seems insane

[lean sail]

thats unfortunately just going to be a part of setting up your game. I mean I dont even think your current collider makes sense to use if you need the doors to open and parts that can be destroyed

those would have to be separate objects

[chrome marsh]

all openable and removeable car parts are seperate objects already

[hexed pecan]

A tool that would align a collider to the mesh by selecting a couple of vertices would be pretty cool

[chrome marsh]

i found an asset store item that essentially makes a voxel representation of your mesh with colliders, but it was made in 2017 and allegedly does not work anymore 😢

[hexed pecan]

Voxels sounds horrible for this

At least if they are all axis-aligned

It would be all jagged right?

[chrome marsh]

yes, not rotated, litterally just like voxelart

[lean sail]

I wouldnt look for separate tools or workarounds for this. It's really just work that needs to be done, which I mean should've been known when this feature was thought of.

[chrome marsh]

i played the long drive which is a unity game, and it has stuff interact inside of vehicles convicningly enough and i thought how hard could it be

[hexed pecan]

That could even be its own physics scene

I know that it's done for larger stuff like ships in games

[lean sail]

ive thought the same before, now when planning what i'll make im avoiding a lot of cool features intentionally

Yea for the object inside the car that could make sense. You'd still be manually moving the object i think though

[hexed pecan]

Yeah I mean the interiors specifically

[chrome marsh]

i did read about those but i also read that they are not as straight forward
also my game is in multiplayer which complicates using physics scenes like 10 fold

i wonder if its okay if my script upon hitting the colliders, moves up through the hierarchy from the colliders until it finds a script that it has to interact with

in this case, the script is on the Hull object

i could use smth like hit.collider.GetComponentInParent<>();

[lean sail]

manually searching up the hierarchy is definitely not desired. im assuming some parent object here has a rigidbody? if so just get that object from the collider.attachedRigidbody

[wraith cobalt]

Have you considered just having the objects inside the vehicle interact with a separate set of colliders from the external physics?

[chrome marsh]

im sorry im not entirely sure what you mean

[chrome marsh]

i js use hit.collider.GetComponentInParent<>();
and it works fine, i think its pretty much the same thing as you suggested

[lean sail]

it really isnt

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Collider-attachedRigidbody.html
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Component.GetComponentInParent.html
the collider already has the rigidbody field. GetComponent needs to search for it

[chrome marsh]

i cant rly do this since the vehicle will only have one rigidbody and i have to access pretty much every mesh renderer in the vehicle, however i could initialize alot of stuff and optimize my code in a way that i think i could actually use this instead, but atm it seems very complicated

[lean sail]

whats complicated about it? it literally is just a reference to the attached rigidbody. Related scripts should be on that same GameObject anyways
im not saying you should have multiple rigidbodies if thats what you meant with the first sentence

if you have a setup where there are scripts scattered across the hierarchy and you need to go find them in the parents, you should 1000% reconsider the setup

[chrome marsh]

no with my code it wouldnt work well atm
id have to change how stuff is modified through code during runtime if all i get is the highest parent rigidbody, as my script currently heavily relies on being local to every mesh renderer, instead of being a script that sits at the top and acc modifies everything beneath it

[chrome marsh]

noted, because that is the current setup, i knew it was bad but i was hoping at the beginning it wasnt gona come back and bite me in the a

[lean sail]

you could even just have code on the same object as the rigidbody (i assume ToyatoHilux?), which has references to the code you need on the Hull

there isn't really a way that what I suggested "wouldnt work". its just really up to how you wanna structure your code

[chrome marsh]

nah, ill do what you suggested and make it so that all objects under the rigidbody dont have their own script, because that would in turn also otpimize another potential huge performance issue (every affected mesh renderer has a unique copy of the initially assigned material) and the car is textured in a way that a single material could be applied to all of it anw, so i just gotta fix that in code.

[lean sail]

its not a necessarily bad thing if the Hull has a script on it to do logic it needs. its just awkward if a child object needs to search for it. Ik this might not be your case but this especially breaks if you have 2 parent objects that have the component and you need a specific one.
So the best thing is if you have some manager object on the parent, ideally with the rigidbody in this case, referencing everything.

im trying to think of a specific example but im drawing blanks

[lean sail]

I guess one example is if you wanted to code getting into the car by looking at it and pressing a button. Since you have a bunch of colliders, if you just raycast you'll just be hitting all the child colliders like a tire. How would you get from the tire to play an animation opening the car door? You definitely wouldnt want to search through parents and children to find the car door. You'd ideally get this manager script from the attached rb of the tire collider. The manager would have the reference to the door.
So basically i wouldn't go and remove all code from child objects to just move them to the parent. It makes sense to have logic on child objects

[chrome marsh]

Thats true, but in my case there isnt just one reason to remove the script from the children, the main concern is that every mesh essentially has its own material which is why im gona recode the script to instead modify a single copy for all car parts of the same car
So per car materials are 1, not 10+

[elfin socket]

When a Mesh isn't readable that means it's not in CPU-accessible memory, which makes it unsuitable for collision, correct?

[turbid river]

hey smart ppl, id like some assistance pls.
i have an object in 2d that moves, and im trying to figure out a good yet simple movement system that will make it move on slopes and loops naturally and without looking janky
any ideas?

[night harness]

a good yet simple solution just doesn't exist tbh

There are many notable titles that completely cut or refused to do slopes for that reason

(eg. Hollow Knight cut slops midway through)

[turbid river]

okay im not trying to do something like hollow knight, more of a vehicle type 2d movement

and im trying to think, should i just use the linear velocity, or maybe use addforce
and also i should probably conserve the velocity so that it carries over slopes and loops

if im missing something, any help would be appreciated

[gloomy osprey]

I got myself into a bit of a pickle and im not so certain what approach to take to get out of it

so in my game all items are scriptable objects, while some items are created before runtime, all gear is generated during runtime which im unable to save the generated scriptable object gear when Saving/Loading

https://paste.mod.gg/lbkenruuqgxf/0 here is my Item Class

how can i make a version of this that will work the same without having to recreate all of my already made scriptable objects?

[leaden ice]

Basically think of your Item SO as like an "Item Template".

Make a new class that is the "runtime" version of an item.

Give the ItemTemplate class a "ToRuntimeItem()" method that creates the runtime items from the SO as needed (e.g. when first loading)

In your game you can directly generate the RuntimeItems.

Saving/loading should be done with the RuntimeItem class basically, although you will run into some complications with being able to properly serialize the Sprite reference (and any other unity asset references).

To fix that problem you'll need to explore either using a custom id there, or Addressables, or Resources.Load

[gloomy osprey]

so when the item is generated it automatically becomes turned into a ToRuntimeItem()

or do i run the items through ToRuntimeItem() on save?

ohhh wait ok

[leaden ice]

they would already be runtime items by the time you're looking to save.

The game would operate entirely on RuntimeItems

The only time the SO would be involved is when you first load.

[gloomy osprey]

so technically the scriptable objects are filled templates that then get entered into the game when loading, and items generated are already runtime items

then in the inventory the player could have many runtime items which are loaded from the save it does

so the runtime item would have all the same fields but does not inherit from the SO in order to stay a POCO, and are generated on loading which makes sense

supposedly it can generate the entire item SO like it had already been then make ToRuntimeItem(Item item), put it as a parameter before entering the inventory

[leaden ice]

pretty much

[gloomy osprey]

well thatll save some time, ill still likely have to change every instance in-runtime with items to runtime items now which shouldnt be too bad

thanks for the assistance

[swift falcon]

how would i access a class from an editor script that is in a regular script? i currently have this but it doesnt work

[quartz folio]

It's either misspelt, in a namespace, or under an assembly definition

Or your IDE is wrong and nothing is wrong (confirm in Unity)

[swift falcon]

what is an assembly defenition

[steady bobcat]

if you arent using asm defs, click the lightbulb and see if it has a fix

probably that you simply put the wrong class name

[swift falcon]

Nah the class name is right

im new and have no clue what asm defs are

[steady bobcat]

dw for now. you have the 2 auto unity ones (Assembly-CSharp and Assembly-CSharp-Editor)

editor one can ref stuff in the base one

[swift falcon]

makes sense, so how can i use that to help me?

[opaque vortex]

Is there a limit to how much you should put into multithreaded burst before it becomes a negative instead of a positive?

At what point is too much

[cold parrot]

Jobs are intended to complete within 1 or 2 frames

[cosmic rain]

Too much of what? Code? Burst doesn't add any overhead on it's own. It just compiles code with certain processor instructions.

In the context of multithreading, there is some overhead(unrelated to burst). So if anything, putting too little code would cause degradation in performance.

[opaque vortex]

Oh ok

[sweet forum]

Rigidbody2D' does not contain a definition for 'linearVelocity' and no accessible extension method 'linearVelocity' accepting a first argument of type 'Rigidbody2D' could be found (are you missing a using directive or an assembly reference?)

wtf is this bullshit

an update fixes one thing and breaks another

[rigid island]

show whole code. what version of unity you got?

[sweet forum]

Unity 6000.0.9f1

it was a beta update

it's not my code because it was working fine last night

[rigid island]

Unity 6 is in lts now

why are you using such old version

[sweet forum]

whats the latest version

[rigid island]

hub says 41f

[sweet forum]

ok thx

another problem

my character isnt moving in the x direction in dynamic while working fine in kinematic

what could be the problem

im using linearVelocity

[rigid island]

do you have constraint on?

[sweet forum]

no only for its arms

but not the main parent which has RB2d dynamic

[rigid island]

wdym , how are they attached ?

[sweet forum]

the arms are just the child

it wouldnt be the arms because my guy can move vertically

it's not the code because it moves fine kinematically

[rigid island]

thats why I said check constraints

show whole code

[sweet forum]

mills.linearVelocity = new Vector2(stickHoriz * 5f, stickVert /* Time.deltaTime / 3.5f);

i printed the values and they're fine

[rigid island]

this isn't the whole code

Time.deltaTime on rigidbody is also not what you'd add to velocity

im using a custom joystick asset

maybe it's in there

ooo

{
    // Store the relative position of the joystick and divide the Vector by the radius of the joystick. This will normalize the values.
    Vector2 joystickPosition = ( joystick.localPosition * ParentCanvas.scaleFactor ) / radius;
    
    // If the user has a dead zone value assigned...
    if( deadZone > 0.0f )
    {
        // If the absolute value of the horizontal position is less than the dead zone value, then just set the horizontal position to zero.
        if( Mathf.Abs( joystickPosition.x ) <= deadZone )
            joystickPosition.x = 0.0f;
        // Else the value is over the dead zone value...
        else
        {
            // Subtract the dead zone from the horizontal position.
            joystickPosition.x -= joystickPosition.x > 0.0f ? deadZone : -deadZone;

            // Divide the horizontal value by the max distance that the joystick can move so that the value will be between 0.0 and 1.0. 
            joystickPosition.x = joystickPosition.x / ( 1.0f - deadZone );
        }

        // Same thing as above just for the vertical position.
        if( Mathf.Abs( joystickPosition.y ) <= deadZone )
            joystickPosition.y = 0.0f;
        else
        {
            // Subtract the dead zone from the vertical value.
            joystickPosition.y -= joystickPosition.y > 0.0f ? deadZone : -deadZone;

            // Divide the value by the max distance the joystick can move.
            joystickPosition.y = Mathf.Clamp( joystickPosition.y, -1.0f, 1.0f ) / ( 1.0f - deadZone );
        }
    }```

at the bottom the y value has a clamp but not x

also // If the absolute value of the horizontal position is less than the dead zone value, then just set the horizontal position to zero.

[rigid island]

try logging the values, is keyboard working?

[sweet forum]

yes

yep that's the issue

deadZone is reading as 0 no matter what

this guy gave me a broken asset

i paid for this fucking shit

[cosmic rain]

Or maybe you're not using it correctly

[sweet forum]

naw it's the code

cuz why would it work for kinematic but not dynamic

[cosmic rain]

Is the deadzone not assigned anywhere? Is it a serialized fields?

[sweet forum]

im reading through it now

it's a long ass script

[cosmic rain]

You can find all the references of the variable in your ide

No need to read everything.

[sweet forum]

still not working

i made everything symmetrical to the y values

i think there's something wrong with unity

[cosmic rain]

Is that variable still relevant? If so, did you check where it's referenced?

[sweet forum]

it's a serializedfield

i have no clue how to use it

didnt read the documentation

[cosmic rain]

Well, that's on you then

[sweet forum]

but it's not necessary because the y value works fine

and everything works fine kinematically

[cosmic rain]

I'd recommend to read the asset docs first

[cosmic rain]

Had to scroll through the channel.

Something must be overriding the velocity then. If kinematic is working, it must be something physics related, like collision or friction.

[sweet forum]

why would it only affect the x value tho

[cosmic rain]

It could be colliding something on the ground when moving sideways. Or the ground has more friction than air.

Code issue is still a possibility too

You should check the values of applied velocity and make sure it's in the expected range.

[sweet forum]

how do i check that

isnt that built in

i dont have access to that code

[cosmic rain]

Isn't the asset that you're using coming with code?

[sweet forum]

thats only the joystick

the velocity code is in another script but i already checked the values

how do i see the values for linearVelocity

[cosmic rain]

If the values are matching your expectations, then it must be the physics system(the things that I mentioned earlier)

[cosmic rain]

Debug them right before/after assigning.

[sweet forum]

ok so i outputted the values for linearVelocity

the x is changing values

should be fine

but my guy isnt moving in x

[cosmic rain]

Then refer to my previous messages

Following this tutorial I made a render texture, I'm trying to make a ui element track over a gameobject, which is normally very easy, but due to how render textures work, I am struggling to find a solution. Any help would be very appreciated (and yes I know that its not actually changing its position right now, thats for debugging purposes)

[vast ember]

I have 2 issues where I generate an ID for collectable gameobject,

1.) What I want is if you collect that item it gets destroyed so it should persist this next time restarting the game, but it doesnt save that destroyed state and that item is once again in the hierarchy.
2.) On the top of it ID is generated every time the game starts.. ID is saved in the save data file but its never loaded again somehow, it always generates a new id for the item whether its collected or not.

Code for reference: https://pastecode.io/s/c9nvbype

[cosmic rain]

2. The IDs need to be assigned at editing time and never modified at runtime.
3. You should have a list of disabled object IDs on a manager or something. When you're loading a save, load that list data, then each object that can be disabled should check if it's ID is in the list. If it is, disable the object.

This is just one of many ways to implement what you're trying to do.

[sweet forum]

how do i give an animation bones

[vast ember]

But if the item is spawning at runtime, how will the id be assigned before runtime?

[sweet forum]

i went to sprite editor and added bones to each sprite in the animation but it doesnt show up in the scene

[cosmic rain]

If the item is spawned at runtime, then keep a list of new items with info like id, type, position and any other relevant mutable data. Then when you load the game, load that list from the save data and recreate these objects. When the object is removed, remove it's info from the list.
Or something like that. Logic 101.

[vast ember]

Got it, will try this

[vast ember]

The main issue i see is its generating IDs even for non collected items again and again when the game starts, even though the id is saved

[cosmic rain]

Well, don't do that. If an item is loaded, it should already have an id. If it's created at runtime for the first time, you give it a new unoccupied Id.

[vast ember]

Right now For testing purposes I have 4 items in the hierarchy that I am not spawning, I set a resource id for them in Awake() in Interaction script which is attached to them. Now When U collect the item it gets destroyed and so does its interaction script too

[cosmic rain]

Check the loading data. If the items were generated in previous sessions, you don't need to do it again. Load them from the save data instead.

[vast ember]

The loading data has the IDs . but still it generates a new one

[cosmic rain]

Don't set their ID in awake. Or at least do it smartly.

[vast ember]

Smartly as in?

[cosmic rain]

Actually, make one step back. Load the save data first, before even generating any items. If the save data exists and items were generated in it,don't generate them again. Or rather, generate still remaining items based on the save data.

[vast ember]

The thing is I am loading the data in Start(), and using interface every other script is fetching that data , I am wondering if the order of saving and loading is causing this issue?

[cosmic rain]

Well, then you've messed up. You shouldn't generate these items until the save data is ready/loaded

[vast ember]

Yeah the item is already in the scene before the script has loaded the data

Since for testing I aint spawning the items, I have just put them in the scene hierarchy

[cosmic rain]

Then you need to decide whether you want to generate them or have existing items, or both.

[vast ember]

Actually both

Some items would remain existing, other would spawn over time

[cosmic rain]

Then you need to keep track of all items. The items created at editing time, should have constant ID, not generated at runtime. And those that spawn at runtime, should have ID generated once, and then saved with the save data.

Then when you load a save, remove items that should be removed and add items that should be added.

[vast ember]

Got it, also is the following a good way to load data into the other scripts or any better way?

  {
      yield return new WaitForSeconds(0.1f);
      this.dataPersistenceObjects = FindAllDataPersistenceObjects();
      LoadGame();
  }


  private List<IDataPersistence> FindAllDataPersistenceObjects()
  {
      IEnumerable<IDataPersistence> dataPersistenceObjects = 
          FindObjectsOfType<MonoBehaviour>().OfType<IDataPersistence>();

      return new List<IDataPersistence>(dataPersistenceObjects);

  }```

[cosmic rain]

If it's a manager object, it should probably have access to all objects/save data without finding it.

[vast ember]

but if the objects are spawning realtime, it would need to find them constantly right?

[cosmic rain]

No. Or at least that would be very inefficient.
Is this script not related to spawning your objects?

[vast ember]

nope its just a SaveManager that saves data and loads data in scripts that follow a IDataPersistence

So I did a coroutine that checks for 0.1f every time for any object of this type

[cosmic rain]

Then you could record the objects with it.

[vast ember]

How?

[cosmic rain]

When you spawn an object and need to keep track of it SaveManager.Instance.AddPersistentObject(object)

Or your spawner should have a reference to the save manager instance if you don't want to use singletons.

[vast ember]

Got it, so no need of a coroutine that finds objects?

[cosmic rain]

No. If you have a reference to it somewhere, you can pass it around to the object that needs it.

[vast ember]

Understood, thank you. I will try all of the things you said

[azure frost]

So... my bro and I have been wracking our brains for a bit.

We want to make a modular character controller system, where various actions or abilities, from walking to sprinting, to swimming, double-jumping, air-dashing, teleporting, you name it, each have their own script and animations.

But we're not sure how the animation tree would even work with that.

[cosmic rain]

Blend trees and layers.

You can basically have any combination of animations with these.

[arctic sparrow]

Are you saying that the animator controller has to account for every possible module if each one is an individual script?

[cosmic rain]

Yep.

[cosmic rain]

You can try reinventing the wheel with playables API if you want.

Would basically be making your own custom animator

Hi, i thought about it a bit and started refactoring my stuff, however

1. All meshes are stored in the runtime texture painter in a list and use a single material
2. Projectile hits a collider, for performance reasons then gets the attached rigidbody and gets its component RuntimeTexturePainter
   How does my projectile script properly pick the mesh of the object it hit through this script, keep in mind that colliders are simple box colliders as children under the mesh
   i believe in this case i am kinda forced to use MeshFilter meshFilter = hit.collider.GetComponentInParent<MeshFilter>();

[steel vortex]

Yo guys have a question what is better pressing "E" to sit on the computer or pressing left mouse click to get in?

Im not sure what key better is to sit on the computer for my horror game

[leaden ice]

#archived-game-design

[steel vortex]

thanks 👍 , didnt saw this channel

[lean sail]

i dont really think i know enough about your setup to see why you'd need this regardless. It does sound a little bit odd to me that you'd need to get the mesh and do something with it from a projectile

[chrome marsh]

i cant get UV coordinates from rigidbodies since they are forced to use non-convex or primitive colliders, i have set up a system for returning UV coordinates manually but it requires direct access to the mesh

[terse surge]

can someone double check in my math is right, imtryna get the angle of the upper corner:

float angle = Mathf.Rad2Deg * (Mathf.Asin(a/ c));

is this it?

[lean sail]

https://www.mathsisfun.com/algebra/sohcahtoa.html
sin(θ) = opposite / hypotenuse so you either need to use B/C or use cos

[terse surge]

and to get a direction vector do i do this? (holeCheckDistance = B)

float angle = Mathf.Asin(holeCheckDistance/hypotenuse);
Vector2 ray2Direction = new Vector2(Mathf.Cos(angle), Mathf.Sin(angle));

[lean sail]

whats the problem you're actually trying to solve here? how are you even getting this triangle in the first?

(Mathf.Cos(angle), Mathf.Sin(angle)) surely can be a vector. I dont know if this would be a vector that you really need

[terse surge]

sending a ray top to down (line a) to detect ground, same with c, a ray to detect ground. if a doesnt hit ground but c does, that means its a jumpable gap and the enemy is close enough to jump. i get the triangle by getting transform pos +half the length of the enemy added to the x axis as the starting point, and B is a public field set, its the hole check distance, and i do Pythagorean theorem to get C

[terse surge]

when we get C this way we only have length, not direction, was getting this vector to be the direction

Vector2 hypotenuseDirection = (new Vector2(holeCheckDistance, -sr.bounds.extents.y)).normalized;

maybe this is a better way to get the vector?

[lean sail]

ok yea so you are doing this a bit backwards.
You must have the position of where A starts since you're raycasting from there. You have the length of B (hole check distance), meaning you can calculate the end point of where they can jump to. These are 2 positions
Get C from subtracting these 2 positions, b-a

[lean sail]

if -sr.bounds.extents.y is where you always start the downwards raycast from, then yea this is basically what i said in the above message

[terse surge]

meaning you can calculate the end point of where they can jump to. These are 2 positions
so... an overlapcircle with a small diameter in that position?

[lean sail]

did you by chance use AI for this..? i really question how you got the above formula without even really understanding what I wrote

[terse surge]

i tried to figure it out msyelf and then fed it into ai and it gave me this which seemed like a better option

[lean sail]

Yea I dont help with AI stuff.

[terse surge]

alrighty then

[compact carbon]

hey, im having a problem where im trying to make something pivot toward another object, the thing im tryna make pivot only rotates when i move the camera for some reason and also doesnt even rotate right??

the part that actually rotates the pivot.

{
    if (swinging)
    {
        Quaternion lookRotation = Quaternion.LookRotation(GM.GetSwingPoint() - transform.right);

        lookRotation = Quaternion.Euler
            (
                Mathf.Clamp(transform.rotation.x, MinX, MaxX),
                Mathf.Clamp(transform.rotation.y, MinY, MaxY),
                Mathf.Clamp(transform.rotation.z, MinZ, MaxZ)
            );

        transform.rotation = Quaternion.Slerp(transform.rotation, lookRotation, Time.deltaTime * rotationSpeed);
    }
}```

[leaden ice]

transform.rotation.x etc are very very wrong here

You can't use quaternions like that

[compact carbon]

so how would i fix it, im not exactly great at scripting

[heady iris]

transform.rotation.x is the first part of the quaternion -- it's like a complex number (1 + 2i), but with four parts

hence why it's borked

Note that clamping the world-space rotation doesn't really make sense

[compact carbon]

so would i make it localrotation

[heady iris]

Start by getting rid of the lookRotation = ... part entirely

it should then rotate property (just without any limits)

er, the lookRotation = Quaterion.Euler... part -- keep the first line :p

[compact carbon]

well, it didnt exactly work. it still doesnt update with the swing

[latent latch]

Eulers? In my 3D engine?

[compact carbon]

i hate quaternions

is there a simple way i can make it look at the swingpoint and clamp the X

[heady iris]

clamping the X euler angle isn't meaningful on its own, since the meaning of the X component depends on the Y component!

rotations can be tricky to reason about

[heady iris]

what does this mean?

[compact carbon]

as in when i swing it doesnt update unless i move the camera for some reason

[compact carbon]

would quaternion be beginner, Gen, or advanced?

cuz ill have to ask in one of those

[naive swallow]

The best category for Quaternions is "Don't"

[rigid island]

You dont even need to worry about quaterions as you never should be touching them

use the Euler to Quaternion functions

[compact carbon]

well idk how i can make this pivot point at the swing point but not just when the camera moves, i want it happening all of the swing.

i cannot do this for the life of me

i managed to get it to where it will do it all swing but i cannot get it to clamp the Z

[rigid island]

One thing is certain you never pass Quaternion values to a Euler to then put it back into a quaternion

[rigid island]

most of the time when you clamp you should be clamping a separate value/variable not the axis directly

[compact carbon]

ok, how can i add a clamp to the X,Y, Z on this code.

{
    Quaternion lookRotation = Quaternion.LookRotation(GM.GetSwingPoint() - transform.position);

    transform.localRotation = Quaternion.Slerp(transform.localRotation, lookRotation, Time.deltaTime * rotationSpeed);
}```

[rigid island]

say you want to clamp xRot
you would create a float value for it to then pass to the Euler

[compact carbon]

oh so i made a value for the x y and z and apply them to the x y z

[rigid island]

xRot += someInput * speed
xRot = Mathf.Clamp(xRot, min, max)
something.rotation = Quaternion.Euler(xRot, etc..

just an example

[compact carbon]

im very confused, im unsure on how to assign this. I might just be stupid?

{
    if (swinging)
    {
        float zRot = Mathf.Clamp(90, -90, 90);
        float yRot = Mathf.Clamp(90, 90, 90);
        float xRot = Mathf.Clamp(0, 0, 0);

        Quaternion lookRotation = Quaternion.LookRotation(GM.GetSwingPoint() - transform.position);

        transform.localRotation = Quaternion.Slerp(transform.localRotation, lookRotation, Time.deltaTime * rotationSpeed);

        transform.localRotation = Quaternion.Euler(xRot, yRot, zRot);
    }
}```

[naive swallow]

Not sure what's the plan using clamps with three constants

If you're defining the numbers directly, why clamp?

Just use values you actually want

[compact carbon]

the values i want are only between -90 and 90 on the lookRotation but i need to clamp them for that to work

[naive swallow]

Okay, but, 90 is always between -90 and 90

so why clamp? Why not just use the 90 you're passing to clamp?

[compact carbon]

oh ye lol

the only axis i want to move is the Z axis, but i also need to clamp said axis

[hexed pecan]

I think the idea is to have float zRot = etc. as member variables, not local variables

[compact carbon]

float yRot = 90;
float xRot = 0;``` i fixed that though

[hexed pecan]

Declare them in the class, not in the method

This way the machine remembers the value and you can modify it every frame

[compact carbon]

yRot = 90;
zRot = Mathf.Clamp(90, -90, 90);```

now there member valuies

[rigid island]

this doesnt make much sense

[naive swallow]

Again, just set zRot to 90

[compact carbon]

im new to scripting so this doesnt make much sense to me

[rigid island]

why are you clamping 90 if its a constant value

[naive swallow]

clamping 90 between -90 and 90 doesn't make sense

that's just gonna return 90

[compact carbon]

im so confused

[naive swallow]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Mathf.Clamp.html
Mathf.Clamp(a, min, max) will return the value of a, but if it's less than min it will return min. If it's greater than max, it will return max.

So, let's plug in the numbers.
Mathf.Clamp(90, -90, 90) will return 90, unless 90 is less than -90, in which case it returns -90. If 90 is greater than 90, it will return 90

Now, we know that 90 is not less than -90, and we know that 90 is not greater than 90. So it will return 90

No matter what, every time the code Mathf.Clamp(90, -90, 90) runs, the value it spits will be 90

So, you should just use 90 instead

[compact carbon]

so how can i make it go into the negatives

[naive swallow]

Give it a value that is negative

90 is never negative

so it won't be negative

[compact carbon]

but i will swing on it, so i need it to be able to go 90 to -90 and back to 90 if needed depending on the swing

it has to start at 90

[naive swallow]

Right now, zRot will always be 90.

[compact carbon]

so how can i fix that

im just really confused

[naive swallow]

Well, what do you want zRot to be

[compact carbon]

i want it to be pointing at the swingPoint, when doing whati showed in the video

[naive swallow]

Code runs one line at a time, top to bottom. Every fixed time step, you're setting zRot to 90 here. It doesn't matter what it used to be. It is now 90

And then you set the object's rotation to 0, 90, 90 at the end

So, if you want zRot to change between frames, you can't just obliterate it every frame by setting it to 90

[compact carbon]

this is the current state of it btw

{
    xRot = 0;
    yRot = 90;
    zRot = 90;

    Quaternion lookRotation = Quaternion.LookRotation(GM.GetSwingPoint() - transform.position);
    Quaternion desiredRot = Quaternion.Euler(Mathf.Clamp(lookRotation.x, 0f, 90f), 90, 0);

    transform.localRotation = desiredRot;
}```

[naive swallow]

Okay, good to know, you're no longer setting local rotation to a constant every frame

but we're back to the old problem. lookRotation is a quaternion. lookRotation.x is not the degrees about the X axis the object is rotated on

it's part of a four-dimensional vector representing the object's orientation

[compact carbon]

how can i make it 3 dimensional? i cannot even

[naive swallow]

and individual components of that vector do not mean anything to humans

[compact carbon]

like picture 4d

[naive swallow]

Exactly

so stop trying to access individual elements of a quaternion

you will not ever need to do that

[compact carbon]

so how can i make something point at something else without using Quaternions

[naive swallow]

just forget the fact that x, y, z, and w properties even exist

[naive swallow]

the lookRotation is that. If you set the object's rotation to lookRotation, it'll point at something else

(in this case, GM.GetSwingPoint())

[compact carbon]

i do want it to point at that but i dont want the other axis like X and Y but i do want Z but only between -90 and 90 (atleast these values in engine)

[naive swallow]

The issue with that is, there are an infinite number of ways to express the exact same orientation in a 3D vector of degrees

[hexed pecan]

Z axis is the twist/roll axis. Are you sure you don't want X axis?

[compact carbon]

not in my case, my object is rotated weirdly so i cant really do it like that

and i dont want it to be a child object

[naive swallow]

If something's at 0, 0, 90, then it is also at 0, 0, 480 and 0, 0, -270 and 180, 90, -90 and so on

[compact carbon]

for me y is forward x is up and z is right

[compact carbon]

that is confusing asf

[naive swallow]

This is why unity uses Quaternions to represent rotations

Because degrees are cyclical, and 3D rotations are susceptible to Gimbal Lock

Which means things that you think should be simple actually don't work the way you think they do

[vague cosmos]

What's the best way to check for a string of inputs, for example the konami code? Currently, i have every input being recorded into a list, and then checking for a sub string, but this is not working properly for more than one combo input.

I'd say maybe a dictionary where you'd string build then compare it at the current input string

Or something like regex perhaps, but I'm not too knowledgeable about fighter games

[vagrant blade]

No, and if there was it would be so small it would be considered non-existent for the majority of anything people are creating in Unity. In the end, choose the most readable option, which would be Mathf.Max in my opinion.

[vagrant blade]

@distant thistle You can create a #1180170818983051344 to share your game.

[craggy veldt]

there's a difference.... UnityEngine.Mathf is hardware accelerated (intrinsify/vectorized) on il2cpp

all of them in UnityEngine.Mathf

guaranteed

[vagrant blade]

Sure, if you want to dive deep into it, people have made benchmark comparisons online and have argued the results.

But as I said, for most what people are doing at a beginner level, it's a non-issue. Readability over micro optimization.

[leaden ice]

There's nothing to vectorize there though it's basically just a single if statement

[craggy veldt]

not the statement.. but the call to mathf.Max

if statements cant be vectorized

[leaden ice]

Vectorization is related to for loops

[craggy veldt]

incorrect

[leaden ice]

Applying the same operation to several contiguous memory elements at once

I'm saying there's nothing inside Mathf.Max that could be vectorized

Also isn't Unity.Mathematics the highly hardware optimized one

[craggy veldt]

it is automagically auto vectorized in il2cpp

nah(sure mathematics... BUT....) mathf as well

[cold parrot]

min/max moves are atomic assembly instructions, you'd likely get those in any compile.

[craggy veldt]

typically, not in all cases... even the regular System.Numerics.Math

thus they give us System.Numerics.Math.MaxNative in net 9 now

that one is guaranteed

but with a catch, it is fast but not tied to IEEE specs

meaning it might behave differently on other platforms

this conversation somehow getting out of context to system.numerics

lol

[cold parrot]

the lesson in all this is, someone will always pop out of hole and throw some arcane details at yyou that are entirely irrelevant to 99.9999999999% of people.

[craggy veldt]

agreed and pardon for my text wall above 😅

incase any of you wondering https://learn.microsoft.com/en-us/dotnet/api/system.single.maxnative?view=net-10.0&viewFallbackFrom=net-9.0

tons of Native stuff in 9-10, which is... great

[cold parrot]

thx, doesn't have any info though

[craggy veldt]

yeah, they're testing it since 9.... y'all will see lots of these in the next version guaranteed

[craggy veldt]

if you want to know what they do, feel free to ask it on c# server, fat chance the maintainer themselves will directly answer you..

[crisp flower]

anyone know of an asset or can suggest a methodology for having a research tree in a game? Hoping there's a framework I can just easily implement somewhere...

[gleaming current]

Hello fine people of this discord, i want to create a game similar to Farm Merge Valley, basically a merge game but cannot figure out how to correctly implement the merge mechanic, essentially, when i drag an object on top of a similar one, it should generate the 'next evolution' of said object, if there is at least one more similar object on a tile nearby. i think the function to check for neighbouring tiles doesnt work correcly as my console states that there are never enough objects for the merge to take place

[mossy shard]

Is it better to have only one Update function which calls any other metods of the game or have multiple?

Dk how Unity handles the Updates rlly

[atomic whale]

is there any fix to this inspector bug? first pic is the position of a gameoject according to the inspector. second pic is printing the result of the math which the objects position is being set to and then also the objects position as in obj.transform.position just to double check. in the scene the object visually also has a y of 0.

[atomic whale]

hard to tell without seeing your code. I'd personally do it as follows: move obj, check all 4 sides of obj for merge partners, if found also check partners 4 sides, if found merge. should be easily doable in a 2dimensional array.

[gleaming current]

thanks, I'll try that

[leaden ice]

Position in the inspector is local position

It's not a bug

It probably has a parent that is offset

[atomic whale]

it doesnt have a parent

[leaden ice]

"better" is vague. It's a tradeoff

[leaden ice]

Some other thing is happening then

There's no way there's a bug in the inspector

[atomic whale]

when I move the object myself slightly it jumps from whatever it is to the correct number

slight nudge upwards and its back to displaying correctly

[leaden ice]

Are you sure it's not actually a really tine number in scientific notation?

e.g. -1.5240894548e-8

that's probably it

[atomic whale]

that. is the case.

another mystery solved. ty

there isnt actually any reason for this to happen as I am multiplying the position vector by smth and 0 * x is just 0 if I'm not mistaken

[leaden ice]

you'd have to show the code

probably a floating point precision issue

[atomic whale]

oh yea thats interesting I've exported a simple quad from blender but when I read the y of a vertex its at -2.185569e-08.

[mossy shard]

how so, what would change and how

[leaden ice]

The main difference is how you have to organize your code

The "each object handles itself" pattern is quite convenient and easy to think about

You sacrifice some performance to have a cleaner more maintainable codebase

Sometimes that tradeoff is worth it and sometimes it's not

[gleaming current]

regardless of that specific problem, as a coding noob - where can i best learn to improve my coding skills and solve problems that are not specifically found on youtube?

[atomic whale]

there is no easy way to answer this. The best thing pretty much is 🌟The Internet.🌟 if you cant find your exact problem try to break it down into smaller more generic pieces which might be easier to find a solution for.

[gleaming current]

thanks mate, I'll try that 👍

[remote cobalt]

I have a random grid generator using a grid element that renders tiles

but its overlapping them

I found the issue which was the tileset was putting one over the other, anyone know how to fix that

Any help would be appreciated

[fluid crown]

It will if each sprite is an object in the same layer

You can fix easily if using URP

Change the transparency axis in the renderer settings

[night patio]

if I want a cancellable asynchronous process, should i use coroutine wrapper or async await wrapper?

[fluid crown]

coroutine is not async

[night patio]

then for cancellable process, do u think coroutine or await is better

[vestal arch]

i mean, depends on what you're doing, i guess?
coroutines are cancellable

[night patio]

like if a building is running a process but it suddenly get destroyed

[fluid crown]

Use Coroutine if you will use unity stuff like monobehaviours

[rigid island]

awaitable is also an option and has cancellation token like Tasks do

[thick sable]

anyone know of ways to do procesing on animations? I have mocap takes that unity recorder seems to drop out on a keyframe basis
was looking to make an editor script to address this but there's seemingly no documentation on reading curves from an anim file

[wide totem]

can a dict with gameobject values hold the same gameobject at two different keys?

[rigid island]

ofc

[hard estuary]

Yes. Only keys have to be unique.

[rigid island]

as long as keys are unique

[wide totem]

okay just making sure ty

rewriting half my script because i named two variables too similarly and got them mixed up when adding to a list will teach me a lesson hopefully

[rough cobalt]

hey guys, is it possible to rotate a physics.overlap sphere along with the object it takes as center?
As you can see from the pic, the sphere always stays under the object even if it's rotated cause i only give it a center reference:

objectsInRange = Physics.OverlapSphere(this.transform.position + new Vector3(0, -5 ,0), spotlight.range/2, detectionLayer);

is it possible to make it sensible to the object rotation?

[naive swallow]

A sphere would be identical no matter which way you rotate it

That's kind of definitionally what a sphere is

[rigid island]

btw you can see the real gizmos if you go to Physics Debugger

[rough cobalt]

i meant that the contact point is rotated ofc

[naive swallow]

If you want it to spawn at a different spot, you'll need to change the spot you spawn it at

[leaden ice]

Are you asking how to change the position where you do the overlapSphere based on the rotation of the object this script is attached to?

[naive swallow]

You're creating it 5 units below this object so that's where it's gonna be

[leaden ice]

use transform.TransformPoint(new Vector3(0, -5, 0))

[rough cobalt]

a behaviour like this to be precise:

[leaden ice]

or transform.position - transform.up * 5

yep - follow what I wrote above

[rough cobalt]

lemme try that

[rough cobalt]

works like a charm man, thank you so much

could you explain me what that does or link me to the docs?

[leaden ice]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Transform.TransformPoint.html

jsiut gets that position in the object's local coordinate space

or "from the object's perspective"

[rough cobalt]

thanks a lot

[night sparrow]

How do i batch multiple game objects together?

I have a scene where i want to dynamically add moving gameobjects. However i can easily reach 1000 batches since every gameobject has it's own draw call

They use the same sprite(2d), how can i draw them using a single draw call?

[visual flare]

is the max Random.Range (minInclusive, maxExclusive) guaranteed to be exclusive? i keep getting out of range exception in available[Random.Range(0,available.Count)];

[vestal arch]

yes, and show more code in context please

How do i make a drop down menu in the inspector depending on another variable?

For example i have a variable that can have n items, i want each item to be in the dropdown menu of another variable

[somber nacelle]

Custom inspector. Check the pinned documentation in #↕️┃editor-extensions to learn how to make one

Hey can someone else me out? I’m tryna implament multiplayer into my 6v6 fps game I need it to be able to Do matchmaking and party’s and lobby’s if anyone knows the best way please lmk

[rigid island]

most likely you have no items

[visual flare]

tss, you're right

[wide totem]

why does vscode sometimes allow me to Random but sometimes has to make me specify unityEngine.Random

[cold parrot]

when you have a using System; and a using UnityEngine; statement in the same file you need to disambiguate between System.Random and UnityEngine.Random

[wide totem]

does unity just sometimes add one of them into the file? i swear it just happens halfway through writing the script sometimes

[stable osprey]

Unity adds UnityEngine if you "Create new MonoBehaviour" via C#.

but VS/VSCode may add them as you type if you have certain options enabled

[wide totem]

ah, thank you

[stable osprey]

like when you type MonoB and autocomplete to MonoBehaviour, VS/VSCode's smart autocomplete adds the necessary Using

[pastel halo]

Hey, i've got a plugin question. Would it be theoretically possible to have a performant "subdivision" plugin that is applied as a modifier on a skinned mesh?

Like how in most animation software, you rig a lower definition model, then apply a subdivision modifier to smooth the visuals after the armature/rig (uncollapsed, just in the stack)

It's beyond my scope but I was curious if it's even possible in unity. It would be great for cinematic stuff, since trying to export subd out from anim software collapses it and results in crunchy surfaces (unweighted because collapsed)

[wraith cobalt]

Shader based tessellation is essentially that, though it has caveats.

[soft shard]

Technically, most commercial libraries like Photon, Fishnet, Mirror, Netcode (Unitys multiplayer solution), etc can all do those requirements, some can do more than that as well so it may be worth looking at the features and paid license plans for several multiplayer solutions and pick the one that best fits your needs, some are more beginner friendly and others might require a more extensive knowledge of networking, then there is also the option of running your own solution or using 3rd party distributors like Steam if you decide to publish your game there, they have SDKs that handle matchmaking, friends, and a bunch of other cool features - I will say though, playing with different multiplayer solutions and designing your game with multiplayer in mind from the beginning, is much easier than injecting a multiplayer solution into a existing game, not impossible, just much more difficult, likely with a good bit of refactoring game logic

[last raven]

anyone knows if this is a bug in unity 6 or do I have to do this in some other way? I have game maximize game view after loading in editor, it worked in previous version but in new version view.maximized = true causes NRE if I call it early (still works fine later)

[night patio]

if i were to learn UniRx, how long would that take? anyone got recommended UniRx materials?

[cosmic rain]

Totally depends on your experience with unity and programming in general. From what I remember UniRx is not very well documented and has even less tutorials, so you might need to be able to read the source code.

[night patio]

im an intermediate at Unity but ye i've been googling and havent seen any good unirx materials

[rigid island]

Unity has awaitable now, what would even be the point of using something like unirx

[gloomy helm]

why does my camera cause me the error Screen position out of view frustum (screen pos 960.000000, 539.000000) (Camera rect 0 0 1920 1080) when i teleport my car's rigid body only with this code

https://paste.ofcode.org/3bbzAeAgSmzaRZTe4xB4m2P

[rigid island]

also according to their github, unirx is no more now its something like R3 now

[night patio]

im working on old versions and dont want to upgrade yet so im looking for options

[rigid island]

I see. I would be upgrading at some point.

[gloomy helm]

mb

[rigid island]

which one is the camera ? its hard to tell from this function only

[gloomy helm]

the camera is attached to the car

[rigid island]

in the code

[gloomy helm]

no

idk the issue does not happen in the editor

[rigid island]

How does the camera follow the car

[gloomy helm]

only happens after building the game

[gloomy helm]

the camera is the child of the car

mb

[rigid island]

So when you teleport the car, the camera attached stays with the car but throws that error ?

where is the car

[gloomy helm]

no i if i teleport the car lets say with random range and keep the Velocities the same the issue does not happen only when i teleport it with that piece of code

i have removed all canvases in the scene

[rigid island]

where does canvas come into play ? Also you should consider not using such inline code like this, its very hard to read and there is much repetition

[gloomy helm]

i thought maybe the canvas might cause the issue

[rigid island]

if you try to move one it might.

that it would affect the camera tho

[gloomy helm]

i have no canvas or ui i removed it all

also btw i have built the game before and i was not experiencing any issues

[gloomy helm]

i just fixed by just not resseting the velocities

but i need to know why that would cause the iisue

[rigid island]

uhh maybe something else, that seems very unlikely to be a cause

[gloomy helm]

no thats all i did

im confused

[rigid island]

yeah not sure why that would be...I never had such an issue ever when resetting vel on rb

Im sure camera being parented to a dynamic rb doesn't help

[gloomy helm]

ok i just used a camera follow script so the camera is not the child of the car i thought the cam follow script was the issue

so should i just make the rb kinematic ?

when i dont want it to move

[rigid island]

No but if you want camera to follow the vehicle it would be better to use Cinemachine

[rigid island]

maybe

[gloomy helm]

k let me try

ok that broke the camera again

let me use ""yield return new WaitForEndOfFrame();""

[rigid island]

I mean if its physics it would be WaitForFixedUpdate

[rigid island]

btw what is the fullstack of the error ?

[gloomy helm]

wdym?

[rigid island]

like the stack trace

[gloomy helm]

i only get the error on the build so i have to turn on dev mode and all i get is Screen position out of view frustum (screen pos 960.000000, 539.000000) (Camera rect 0 0 1920 1080) repeated

screen pos the numbers are the mouse's position

[rigid island]

open the PlayerLog see if its there

[gloomy helm]

wait

ok yield return new WaitForEndOfFrame(); fixed it

let me remove that

[rigid island]

weird..still think might be something you're doing to the camera thats not supposed to be doing

[gloomy helm]

how do i get to the log file i also locked the mouse bc i thought it would be the problem

[rigid island]

https://docs.unity3d.com/6000.0/Documentation/Manual/log-files.html

Player-related log locations

[gloomy helm]

should i send it?

like the txt

[rigid island]

use paste site

[gloomy helm]

https://paste.ofcode.org/B2eQ7MmkpNEC4TrEizqfwd

ignore the Object reference not set to an instance of an object it was because i removed the canvas

ok turns out yield return new WaitForEndOfFrame(); did not fix it

[rigid island]

naa.
where do you have ScreenPointToRay in your code?

[gloomy helm]

i dont have that

i never usse ScreenPointToRay

ok so i just made sure it was the velocity and it was bc i removed all velocity canceling and kinematic = true

and now it works

also idk if this helps when i did yield return new WaitForEndOfFrame(); it only starts spitting the error at only when moving the mouse so it does not just keep doing it repedetlly

[rigid island]

if you show inspector for the camera there is probably something there

[gloomy helm]

this ?

[gloomy helm]

also i tried reinstalling the editor and building another game and the issue still persists
