[onyx cypress]

it ended

[rigid island]

Vector3.Distance(transform.position, target)

put this in a variable and print it

[onyx cypress]

ok

[rigid island]

well yeah save manager has all the saveables

[storm wolf]

But how do the objects become saveable

They have to implement it right

[rigid island]

yes thats why only ISaveable objects have their own SaveData class for exaample

they need to follow the strict rules enforced by interface

[onyx cypress]

it 2.55

[storm wolf]

Ok so they do know about it then

[rigid island]

thats when it stops it still has 2 meters left?

[onyx cypress]

yea

[rigid island]

it really depends, there are a dozen ways to implement this tbh.

[spring creek]

Target is not on the ground

[onyx cypress]

no i put it on the ground

[spring creek]

It is at y value 257, while your player is at 254
It says right there in the logs

[onyx cypress]

thats not my player

thats the enemy

[storm wolf]

Only thing im not understanding is how it becomes ISaveable for the save manager i get that it sends itself to the save manager into like a list of isaveable or whatever

[spring creek]

Ok, irrelevant though
The target is at 257 and the ENEMY is at 254

That is 3 meters above the enemy
Oh, 2.5 about. So exactly the distance you logged of course

[rigid island]

ok I will show a quick example

[onyx cypress]

ok let me see than i changed all the numbers of player, enemy and chekcpoints to 256.5

[spring creek]

Why 256.5?

That is about 2 meters above the enemy

The enemy is at 254.44

That is what you need to have all the waypoints at if the terrain is flat

[steady moat]

Just ignore the Y instead of positioning them at the same height ?

[spring creek]

Very good point

[onyx cypress]

i put the transform to 254.44

now its not moving to even one checkpoint

[spring creek]

Do what simferoce said

Just check the distance to a vector using the x and z of the target, and ignore the y (plug in the enemies own y value)

[onyx cypress]

ohok

sorry

https://paste.ofcode.org/?edit=x8n6jNfdU3Ei3eSsn62gGR

like this?

[spring creek]

I am not seeing any difference. It is still checking distance between transform.position and target

new Vector3(target.x, transform.position.y, target.z)

[onyx cypress]

bro i dont get anything

im just gonna scrap this project

to be honest

[onyx cypress]

btw new Vector3(target.x, transform.position.y, target.z) isnt a line in my coe

[storm wolf]

Is it smth to do with custom attributes? Trying to read up a little

[spring creek]

I know. That was the line of code you would use when doing a distance check. It creates a vector at the position of the waypoint in the x and z directions, but at the same y position as the enemy. Thus you would not ever have to worry about it being above or below

[onyx cypress]

so when i make that what do i do

[spring creek]

Use it in you distance check, instead of just target by itself

[onyx cypress]

ok

[spring creek]

You could also make a variable and set that when you assign a new waypoint as target, so you don't have to create a new vector every frame
But then it would be the y position of the enemy at that point in time and not update

[onyx cypress]

https://paste.ofcode.org/?edit=x8n6jNfdU3Ei3eSsn62gGRlike this

did i do it right?

.. it worked THANK YOU SO MUCJH

[rigid island]

not really but you could do it if you want to.
Why not just start with a simple system then go from there? I feel like you might be prematurely creating a heavy system when a simple one might suffice

how much data are you saving from how many different data types

[storm wolf]

I have one created already and it is pretty simple I was just wondering about the interface approach as its probably better than mine

Currently i just put everything in a PlayerData class and serialize and save that

[rigid island]

simple is usually better 🙂

interface adds a whole other layer of complexities

[storm wolf]

Why use it then

And I am just curious how that approach works

I was thinking about the event option that seems like a good approach too

[rigid island]

idk there isn't a specific way to do it thats why i'm wondering what you're trying to accomplish

I have interface but had to use a Dictionary with it but that now adds complexities of GUID and ofc not being able to serialize it with native serializer

[storm wolf]

Lets say i have a bunch of coins in a bunch of different levels and I want to save if they have been collected or no

[rigid island]

my specific usecase was doing items you can store inside Crates / Inventory / Backpacks

so yeah I had to make Unique IDs for each item, because once you pick them up and save, You dont want the game obviously spawning more on Load

this involved doing custom dictionary serialization and it was a pain

[storm wolf]

I have done that before but not with an interface

[rigid island]

you dont technically need the interface but it surely helps

I have a video i watched a few years ago on this

lemme find it

[storm wolf]

But if you have a save method with the interface wouldnt you need to serialize in there each time

Yes pls🙏

[rigid island]

https://youtu.be/cwSKPIvWvpM?list=PL-hj540P5Q1hLK7NS5fTSNYoNJpPWSL24
was either this one or the few videos before/after

[storm wolf]

Awesome ill watch in a bit

[unique thunder]

Can you add an ASP.NET API into a Unity solution that gets triggered to run when the Unity project runs? So you don't have to host a API but rather inside the same solution

[knotty sun]

no

[rigid island]

what would even be the point of that

you should not have an API on the client anyway

[cunning burrow]

this is straight up bullying, unity isn't serializing my vector2 correctly...

wait holdon, is it like {"x": 0, "y": 1} or smth

you gotta be joking me if that is the case

[rigid island]

why would it not be

[cunning burrow]

it seemed logical it would parse a tuple as a vector

[rigid island]

which tuple ? they're different types completely

vector can only contain float/int
tuple can have multiple datatypes

List<string> omg = new();
(List<string> omg, Vector3 position, bool, float) crazyTuple = (omg,transform.position, true , 23.3f);```

[cunning burrow]

well anyway it was an easy fix server-side

[rigid island]

oh ok . what was wrong ?

[cunning burrow]

the thing lol

anywaysss

[rigid island]

nice

{} is the vector2 object

x , y are the keys

[cunning burrow]

I just had to change how my server represents positions

I mean my server already does a lot of translations to allow easy serialization in unity

[rigid island]

my server just saves regular C# classes/struct.
In unity i already convert them to that
eg Vector3 goes into a custom Position struct etc.

I use a class library to do it though so Unity project/objects doesnt have to know any of it

[cunning burrow]

I have custom classes but stuff like the game definitions data has a lot of complex dictionaries which unity doesn't parse so I have a custom serializable dictionary type for that and I have to make my server convert these for unity

[rigid island]

oh okay. I lazied out and went for Json.net

[cunning burrow]

umm a debug tecnique but how do I check what keeps resetting my object's position (except idk, going through each script)

[rigid island]

search references to that script first

[cunning burrow]

nah it's the animator for damn sake

but like, I only want it to control z

I might just move it out of the animator tbh

but then I need to wait for animations and shit to finish to change the stupid z

[rigid island]

I think there was a property you can switch on that only controls the properties changed with keyframes

I'm not good with animator so I'm not 100% on that.

[void basalt]

will using assembly definitions noticeably reduce assembly reload times in larger projects?

[spring creek]

It will only compile assemblies that have changes
So most of the time yes, unless you make changes to every assembly before compiling

[rigid island]

not really a code question

[karmic herald]

idk where else id ask sorry 😞

[rigid island]

well..did you read the #💻┃unity-talk description?

[karmic herald]

ah

i can move it there then

[late lion]

Reload time, no. Regardless of which assemblies get recompiled, all of the app domain and all assemblies have to be reloaded.

[void basalt]

what's the point then? It just seems like a hassle if there's no real reload time decrease

[late lion]

When I say reload time, I'm referring to domain reload. Compile time can still be reduced. After you make a change, Unity recompiles and then reloads the domain.

[void basalt]

ah okay

[rigid island]

domain reload can be disabled btw

[late lion]

But I mostly use assembly definition files for organization. It means you can separate code and define clear dependencies between them.

For entering playmode, yes, but not for code recompiles.

[rigid island]

truth

[chilly surge]

Domain reload time is far far higher than compile time.

[late lion]

Yeah, this has been my experience as well. Things like IL post processors found in Entities and Burst can inflate compile times, so I can imagine the ratio between compile time and domain reload differs between projects, but almost certainly always leaning towards domain reload.

[chilly surge]

Not sure about ECS, but I think Burst compilation is async.

Either way though, shaving a second or two off compile time dwarfs in comparison to domain reload taking tens of seconds or even up to minutes.

[subtle spoke]

How can I make sure ENABLE_WINMD_SUPPORT is on?

I've done everything that the Unity docs told me to (IL2CPP, .NET Framework in settings) but my code refuses to believe I have WINMD support (I am on a windows computer)

[late lion]

Are you building to UWP?

[subtle spoke]

No, I just want to use UWP APIs in Unity

specifically Bluetooth LE

[late lion]

I think the app needs to be running in the Windows Runtime to access those APIs, which means the Unity build must target UWP, not Windows Standalone.

I don't know much about Windows Runtime or UWP, but from a quick search, it appears you cannot access WinRT APIs from a regular C# app, for example, without changing the runtime target to a specific .NET version which is WinRT compatible.

[visual flare]

getting UnassignedReferenceException on this:
rigidBody?.AddForceAtPosition(direction, hitPoint, ForceMode.Impulse);
rigid null should skip AddForce, right?
can someone explain what that exception is and how to get around it without expanding the ?. into an if ()

[lean sail]

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

This class doesn't support the null-conditional operator (?.) and the null-coalescing operator (??).

this isnt using unitys null check on it

[visual flare]

drats! I thought they addressed that.
I guess I'll have to expand all these nice targetObject = tmpTarget.GetComponent<MCUnitChild>()?.gameObject ?? tmpTarget.GetComponent<MCUnit>()?.gameObject; into ugly if then... oddly enough it all worked

except for that one...

[lean sail]

unless the rb is being destroyed, im not really sure why the error appears. As far as i know, unitys null check also checks if the object is destroyed

also couldnt that above line just be simplified to
targetObject = tmpTarget.gameObject if it isnt already a game object?

[visual flare]

it only sets target if components exist

[twin egret]

is there a reliable way to call OnDestroy() for a ScriptableObject? i'm having an issue where something that i thought would be destroyed isn't getting destroyed

[cold parrot]

You’re not supposed to destroy them dynamically

if you destroy them in the editor (in edit mode) you should handle cleanup with an explicit call to a cleanup method from the outside.

[twin egret]

oh im not destroying them dynamically. to be clear, what i want is for OnDestroy() to be called when i exit play mode. i have the following code to destroy a sprite that i create using Sprite.Create(...)

private void OnDestroy()
{
    Debug.Log("Destroy called on a theme!");
    if (cachedSprite) Destroy(cachedSprite);
}

[cold parrot]

That’s not how they work. You need to do that some other way. SOs stay loaded in the editor

they do not have a play mode lifecycle

[twin egret]

i see. so if i want to store temporary data related to a ScriptableObject, that needs to be done in another way?

[cold parrot]

Not necessarily, you just have to call that cleanup function some other way

You can hook into the editor application play mode changed event for example (I forget what it’s called exactly)

[twin egret]

https://docs.unity3d.com/ScriptReference/EditorApplication-playModeStateChanged.html

is this what you're talking about?

[cold parrot]

The typical (often recommended) use case for SOs however is to treat them as containers for immutable data, not even holding any internal non-primitive state

[digital falcon]

I'm using the gitignore file but I'm unsure how do I have it ignore the ArtifactDB file in Libary? I put it in the right place with the proper format to boot:

[twin egret]

okay, so i'll have to change my solution then. i wanted to cache some data on the scriptable object but that'll have to move somewhere else

[cold parrot]

It has to be called .gitignore

[digital falcon]

Noted.

Anything else I've missed?

[cold parrot]

maybe

files already tracked by git will not be ignored

[digital falcon]

Oh

[digital falcon]

So if ArtifactDB file is being tracked already, do I need to remake the whole project again?

Cus I did what you asked, same problem like usual.

[cold parrot]

Just delete the .git folder and init again with a correct ignore file

[digital falcon]

Ok!

[cold parrot]

Alternatively close unity, delete the library folder, commit, then reopen Unity

[digital falcon]

Let me try that one. Seems easier.

[cold parrot]

if you have committed the library folder once (by accident) your git repository is however full or useless changes, if you cannot reset the repository to a state before that commit, it’s best to recreate it

[digital falcon]

Deleted the Library Folder.

Git still thinks I have the Library. I think I gotta clear the history.

[twin egret]

are you willing to lose your commit history

[digital falcon]

No

[twin egret]

because you should probably just delete the .git folder and reinit the repo at this point

[digital falcon]

Ok

[twin egret]

wait

you DON'T want to lose your commit history?

[digital falcon]

Is that a bad idea if I loose it?

Mostly as I'm worried it'll delete the main project as well.

Its my first time uploading it to git so nothing much has changed yet.

[twin egret]

you won't lose your files if you do, but if you have a history of commits, you would lose that

[lean sail]

you could always just clone the project, then do whatever you need like try remaking the repo

[digital falcon]

Ok

[lean sail]

tho do you really have anything in the git history? sounds like you just started using it

[digital falcon]

Nope

Just started.

Like legit just started a week ago.

[twin egret]

just go to the folder where your project is (Assets, ProjectSettings, etc.), turn on hidden files, and delete the .git folder

you can reinitialize the repo from there

[digital falcon]

Any notes with the last two?

[twin egret]

you already have a git ignore

unless you're open sourcing your project, it's fine to leave license as none

i haven't touched a git gui in forever so idk if this is going to commit everything automatically

also another question: is using a scriptableobject as the key in a dictionary a good idea or nah

[cold parrot]

Do you even have a proper gitignore file for Unity?

Like this one? https://github.com/github/gitignore/blob/main/Unity.gitignore

[digital falcon]

Yes:

[nimble cairn]

Is there any reason why my FPS portal-like physics based puzzle platformer SHOULD NOT have variable jump height?

The player builds bridges to solve puzzles and get to the end of a level/chamber. The bridge building is the core mechanic. I like the idea of letting the player the decide what type of jump they want to preform for the situation at hand. Keep in mind HOW you traverse the level/movement is a huge part of the game!

All this and I'm still not 100% certain.
If I did add variable jump height how would you teach and reinforce this mechanic to the player with an invisible tutorial?

[cold parrot]

[languid mantle]

Hello, i have a question.
Is there a way to capture the desktop audio? i need to capture current desktop audio and send it via WebRTC for my screen sharing system?

[digital falcon]

Deleted the Library, well:

😿

[twin egret]

just open the scene you had open last

deleting Library deletes your current editor state

[digital falcon]

Done

How do I commit?

New Library, new .git folder.

[twin egret]

whats the history tab got

[spring creek]

Make changes, select them, click on the bottom left

[digital falcon]

Ok

[twin egret]

okay then yeah commit when you make changes

[nimble cairn]

#archived-game-design

[digital falcon]

So just do some random code (//random) and it'll automatically commit?

[twin egret]

no. git will detect changes and allow you to select what changes to include in the commit. after that you may commit

[digital falcon]

Ok

I changed a bit of the coding to try and have Github commit but it doesn't respond.

Lemme try something

[cosmic rain]

Then the changed files are not in the local workspace/repository or are ignored.

[digital falcon]

I have a hunch that this might cause a problem:

[digital falcon]

Its a bit scuffed, but it works. @cosmic rain @twin egret @cold parrot https://github.com/Etoiel/TenWindowsGame

Bonus when after I booted it up on Unity:

So its all good, thanks everyone!

[cosmic rain]

Glad you solved it, but I'd recommend not having your project on desktop. That's inviting all kinds of problems in the future.

[opaque forge]

Hi all, I'm generating meshes procedurally, I want to apply a different texture which would represent a pavewalk on the red parts I drew in the image. I have to cut the mesh, but I'm wondering what is the best way to do this, do I have to create 2 different meshes?

[gloomy path]

Heya, got a question.
Anyone has an idea how to edit the autogenerated Scripts?
Namely the Entities C# scripts, which don't appear in the Data/Resources folder

[knotty sun]

C:\Program Files\Unity\Hub\Editor<editor version>\Editor\Data\Resources\ScriptTemplates

[glossy isle]

hi

how can i add message box

in my game

[knotty sun]

this sounds more like something for #📲┃ui-ux than a code chanel

[glossy isle]

i ask my quetion there ?

[knotty sun]

yes

[gloomy path]

That's what I'm saying, the Entities scripts (baker, system, etc') aren't there.

[knotty sun]

you should use #🔎┃find-a-channel BEFORE asking your questions

[gloomy path]

I'm looking to change the baker template

[knotty sun]

then they may well be in the global package cache for the package

[gloomy path]

Any idea where that might be?

[knotty sun]

A google search away
https://docs.unity3d.com/Manual/upm-cache.html

[gloomy path]

Thank you

[knotty sun]

btw these are not code questions and do not belong in a code channel

[gloomy path]

Got it

[onyx cypress]

hello my audio source keeps on looping every frame, https://www.toptal.com/developers/hastebin

[zealous bridge]

I want to write modules which are engine independent. For example, I would make image filters. They would use Image abstract class I would make. It would have setpixel and getpixel abstract methods. I would use adapter pattern yo make unity, godot, monogame APIs fit into my hierarchy. Each Implementation of my abstract image class would have constructor injected API texture class with pixel read write access. UnityImage will have constructor injected UnityEngine.Texture2D texture; and will inherit my abstract class and I would implement setpixel, getpixel by saying texture.getpixel(x, y). Similar approach would be used to make GodotImage and MonogameImage implementations of my abstract class. This is common practice in industry to use adapter pattern to make different APIs fit into same abstraction and be able to swap implementations.

I just wonder what is best way to write modules (nuget, dll or something else) which is supported by all engines. I initially wanted to use nuget since it enables versioning (different versions of project use different version of module/library). I really don't want to use git submodules for versioning because they are extremely confusing when trying to merge, resolve merge conflict, update. I read somewhere that godot doesn't support nuget but they probably support adding dll (or so files since I am on ubuntu) files to some directory. Do all engines/frameworks support .dll (.so)? Is it easy to setup? What is best way of versioning those dynamic libraries? Do they have good performance? I would typically make git repo for that classlib with .net standard 2.0/2.1 so unity doesnt complain and make a bunch of versions/commits of that library. But that may cause dll hell where different dll files have same name and I don't know which version they are. How should I go with thid dll modular approach?

[stable osprey]

definitely dll

all engines that support C# code should support DLL yeah

and ones that don't support C# code probably still support DLLs in one way or another (untested, but DLLs are a universal programming thing, so I have to assume it's fully working universally)

yes DLLs have good performance. Nuget is best for distribution, others are suboptimal

DLL hell is easy to get in yeah. Plus it can be annoying for devs that want to use and potentially extend them, so maybe you should consider packing your whole engine in a single DLL

yeah seems even unreal supports dll files: https://docs.unrealengine.com/4.27/en-US/ProductionPipelines/BuildTools/UnrealBuildTool/ThirdPartyLibraries/

[zealous bridge]

Should I make some bash script which reads first row of commit message and appends it to dll name? "ImageFilters - added basic filters for rotating.dll" would give me ability to know which version is which since different dll versions would have different names. In csproj of that classlib used to make ImageFilters.dll, I would add line which automatically executes bash script for dll renaming.

[thin aurora]

DLL are universally supported regardless of engine

You can also support C and C++ DLLs in your application by using the extern keyword and loading them into your application

The thing you should worry about is compatibility between .NET versions in your DLL. Generally you want to target a .NET Standard version if you want others to use your library

[zealous bridge]

If all engines somehow supported nuget, what would you suggest as easiest solution regarding performance, versioning and ease of use?

[thin aurora]

For example, Unity supports the latest .NET standard version

But often people use some .NET version like .NET 8 and Unity does not support that

So instead you should also compile for .NET standard if you want to support Unity. You can specify multiple target versions in your .csproj file

And I believe Godot supports .NET 8 just fine but I don't remember for sure

[thin aurora]

I didn't say they support Nuget

Nuget is not a thing you support

Nuget is a general package manager for .NET, but you don't use it with Unity because Unity only allows very specific versions and generally they would need to implement some feature for Unity

That's why Unity doesn't use Nuget but instead has its own package manager

You can "support" nuget but there is no guarantee the dll you download from it works

So anyway

[dusky lake]

you can set a material index per vertex and just have multiple materials on the renderer

[thin aurora]

If you plan on making "general modules" for anything, you should target specific versions so that anybody can use it. .NET Standard, maybe much older versions. You can use processor directives to compile code specific to a version if older versions are not supported.

And considering it's not related to Unity you upload these to Nuget

As for performance, this makes no sense. Nuget has nothing to do with performance. It's up to you to write good code that has good performance

[zealous bridge]

What about using static linking? Is it possible in C#? Is it batter way to deal with dependency version hell?

[stable osprey]

what's static linking now?

no if you wanna get away from it pack everything on a single DLL

as for versioning it's git territory -- nothing to do with anything else really

u might wanna keep a constantly up-to-date public const string version = "0.001beta"; which gets printed upon first initialization if you want.

otherwise organize your branches with release, develop, 0.1, 0.2 etc to keep track of releases -- and only push to develop, only cherry-pick to release from develop, and duplicate branches to version branches before making the DLL

[stable osprey]

also yeah I can see why that is confusing -- I meant to say there's no good way to do versioned distributions unless you use Nuget -- but it's not really supported anywhere except standard C# applications

[zealous bridge]

Ok C# cannot use static libs I didn't know. I have watched some yt recently and found out that godot supports nuget and that there is some github NugetForUnity repo which enables nuget window to visually add nuget packages. That github is someone's add hoc solution which may or may not work every time but at least there is some way to have nuget in unity

[stable osprey]

github has option for release pages now that potentially include changelogs & binaries, but nothing beats Nuget -- since it automatically tells you which are up-to-date

yeah there's an Unity asset that allows nuget downloads but what Fused said above stands

[glossy isle]

check #📲┃ui-ux

[magic vine]

Hey there, Im currently having issues with the rigidbody.velocity.magnitude function
im trying to detect, wether or not the Rigidbody (attached to a different GameObject) is moving with a speed != 0
However, this change is only detected, when the Rigidbody comes in contact with another Rigidbody (ie. comes in contact with an enemy)

After some fiddling around, I noticed that this weird behaviour only occurs, when all 3 axes of the Rigidbody´s rotation are frozen, if at least one of the axes is not frozen, the code works normally
Could anyone help me figure out how I can make this work with all 3 axes frozen?

Code:

using System.Collections.Generic;
using UnityEngine;

public class animationStateControlle : MonoBehaviour
{
    Animator animator;
    [SerializeField] Rigidbody rb;
    
    // Start is called before the first frame update
    void Start()
    {
        animator = GetComponent<Animator>();
    }

    // Update is called once per frame
    void Update()
    {
        if (rb.velocity.magnitude > 0)
        {
            print("Change detected");
        }
    }
}```

[leaden ice]

How are you moving the body

If you're not moving it via physics then the Rigidbody isn't going to have a velocity

[spiral palm]

how would i get the number of lines in a text file?

[knotty sun]

string[] lines = File.ReadAllLines(fileName);
int count = lines.Length;

[leaden ice]

Count the number of newline characters and add 1

[final valve]

i assign the scrollbar right, but when i put it into the prefabs it dis assigns, so then theres no scrollbar assigned? why is this

[leaden ice]

Prefabs can't reference objects in scenes

[final valve]

oh so how do i assign it someway?

[leaden ice]

(assets in general can't reference objects in scenes)

[leaden ice]

Assign it at runtime to the instance after you Instantiate

[final valve]

how? idk how to access the instance from the hierarchy

[spiral palm]

how do i count newline characters?

[knotty sun]

you read every character in the file, compare to newline and increment a count when you hit one

[leaden ice]

Instantiate returns the instance it creates

You don't need to do anything with the hierarchy

[leaden ice]

With an int

[magic vine]

ohhh, that makes sense
yeah, im not moving the body via the rigidbody component

[leaden ice]

then all bets are off

[magic vine]

but thx for the help mate!

[rigid island]

how should someone know what it is on YOUR specific project
Profile and find out.

#1179447338188673034

also this seems unrelated to unity

[modest mural]

that's why it's in the code general section

shrug

[rigid island]

?this is unity help coding channel

your post is not related to that

[modest mural]

my bad, it's not clear that this scripting section is only for asking help with unity as nothing implied this was unity specific scripting questions in the read me channel. removed, sorry for trying to share

[spring creek]

The entire server is for unity only. They don't really specify that for the channels because it is just in the name

[modest mural]

Yeah, that's why I shared a details about a setup I use to make coding my Unity games easier and I put it in this channel because it is titled as code-general which I understood to be related to writing code and using Unity. What @rigid island said is that this is only for asking help questions, not sharing resources.

Thanks for joining in on the unnecessary clarification though about what the Unity discord is meant for.

[spring creek]

You understood wrong. It was clearly very necessary

[modest mural]

clearly

[dawn nebula]

I have a plane here and a perspective camera at a downward 45 degree angle. I want to right click + drag and be able to move the camera along the plane. Any tips?

[leaden ice]

Plane.Raycast to get the world space positions of the mouse. Then it's just a matter of moving the camera by the same offset in world space that the mouse moves

[dawn nebula]

Ya I did something similar and upon right click the camera jerks.

        }
    }

[rigid island]

obligatory cinemachine 😮

[dawn nebula]

I am

[leaden ice]

cinejmachine doens't really help in any way for this

but yea

[rigid island]

well the follow to a new target would be smoothed thats all

but yea lol

[dawn nebula]

I'm moving a target for Cinemachine to smoothly track as opposed to moving the camera itself.

[leaden ice]

you're using Plane.Raycast incorrectly

Or rather, you're interpreting the results incorrectly

[dawn nebula]

I thought it returned the distance to interception?

[leaden ice]

_origin = ray.origin + (ray.direction * distance);```
This is wrong, it should be:
```cs
_origin = ray.GetPoint(distance);```

oh wait that's the same actually

sorry

[dawn nebula]

_>

All good. That's a handy helper method at least.

[leaden ice]

I misread

mainCameraFocus.transform.position = _origin - _difference;```

I don't think this is right

let me check my code for this. I've done this exact thing before

[dawn nebula]

This is what I'm experiencing.

The jerks are a single right click.

[dawn nebula]

Thanks, appreciate it.

[leaden ice]

Does this work @dawn nebula ? I couldn't find my code but I tried to rewrite it:

Vector3 _origin;
Vector3 _cameraOrigin;

private void LateUpdate()
{
    if (Input.GetMouseButtonDown(1))
    {
        var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        plane.Raycast(ray, out var distance);
        _origin = ray.GetPoint(distance);
        _cameraOrigin = mainCameraFocus.transform.position;
    }

    if (Input.GetMouseButton(1))
    {
        var newRay = Camera.main.ScreenPointToRay(Input.mousePosition);

        plane.Raycast(newRay, out var newRayDistance);
        Vector3 newMousePos = newRay.GetPoint(newRayDistance);

        Vector3 diff = _origin - newMousePos;
        mainCameraFocus.transform.position = _cameraOrigin + diff;
    }
}```

[dawn nebula]

Yep, thanks man.

[final valve]

in unity how do i detect the object that hit something? all i can find it the object that was hit, i wanna tp the plr or the object that hit the other object to somewhere

[leaden ice]

Debug.Log($"{collision.gameObject.name}");```

[final valve]

yeah that tells me the object that was hit, not the object that hit it

[leaden ice]

It tells you the other object

[final valve]

ohh

[leaden ice]

this object is just this.gameObject

[final valve]

whats the $ for?

[lean sail]

Itd be quite useless if it only told u what the current object was

[leaden ice]

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

[final valve]

i want the collison to tp the player if the collision was hit tho

[leaden ice]

which object is this script on

[final valve]

a tp script

[leaden ice]

then the player is collision.gameObject

or you might want collision.collider or collision.rigidbody or collision.transform

depending on your needs

The docs will tell you the difference between all of these https://docs.unity3d.com/ScriptReference/Collision.html

[final valve]

so then how would i detect if the plr hit the part to then do smth

[leaden ice]

check if the object is a player

then do the thing

That might mean checking its tag, or checking if it has a specific component on it

for example:

if (collision.gameObject.TryGetComponent(out Player p)) {
  p.Teleport(someLocation);
}```

[final valve]

so where do i now put the function? how do i connect it so it fires

[leaden ice]

In OnCollisionEnter of course..?

[final valve]

it isnt doing anythig tho

[leaden ice]

Start with this

without any if statements

to make sure it's even running

If it's not running at all, you didn't set up the objects correctly for OnCollisionEnter

[final valve]

nothing

[leaden ice]

Ok so - show the two objects that are colliding

show their inspectors

[final valve]

ignore the plr transform its not needed

[leaden ice]

and the player?

[final valve]

its multiplr so i cant just have 1 player

[leaden ice]

Can you show the inspector for the player too?

[final valve]

its why i wanna detect

[leaden ice]

I didn't say anything about how many players you have

[final valve]

yeah but if i connect the player to that transform, it would teleport everyone right?

[leaden ice]

I just want to see the inspector for the player object that you expect to collide with this teleporter

[leaden ice]

Id didn't say anything about doing that

I just want to see its inspector please

[leaden ice]

Ok you are using a CharacterController.

CharacterController does not trigger OnCollisionEnter

[final valve]

oh

[leaden ice]

For that you need to use this https://docs.unity3d.com/ScriptReference/CharacterController.OnControllerColliderHit.html

and I think that code can only be on the CC side

[final valve]

oh

[final valve]

i dont get it

[knotty sun]

what don't you get? You have been provided with an example of how to do what you need

[lean sail]

You should heavily reconsider if you're actually doing multiplayer since you clearly arent familiar with unity basics

[spring creek]

That is a different method you must use instead of OnCollisionEnter. Simple as that 🤷‍♂️

[final valve]

mines a character controller not a ridgid body

[leaden ice]

Yeah what do you think that link is for

[final valve]

rigid bodys

[leaden ice]

Where did you get that idea?

[final valve]

bc it assigns it Rigidbody body = hit.collider.attachedRigidbody;

[leaden ice]

It's example code

It's checking if the other thing has a Rigidbody

It's also completely not important

It's just example code

[final valve]

oh

so how do i put it into my terms

[spring creek]

CharacterController.OnControllerColliderHit

[astral sky]

figured

[final valve]

like that?

[rigid island]

is that how its written in the example documentation ?

[final valve]

i think

[rigid island]

wdym you "think" its literally there wirtten in text

what does it say

[final valve]

the same as what i put

[rigid island]

so what do you think the answer is here

[final valve]

yes

is hit, what has been hit/touched?

[rigid island]

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

[final valve]

theres no "hit" there

[rigid island]

what?..

hit is just a variable name

[final valve]

what for

[rigid island]

man this belongs in #💻┃code-beginner

this is basic c# stuff

[rigid island]

what do you mean what for ?

for the datatype it returns

[final valve]

well im confused bc u sent an atricle of what is what but hit isnt there so idk what hit is gonna be used for

[rigid island]

hit is the variable name for the data next to it, it can be anything.. the name is not relevant

do you know what Method parameters are?

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/method-parameters

[restive ridge]

I made a Debug.Log check for the brake/reverse input. If the car is stationary or moving backwards, and i hold brake, the car moves backwards and the message keeps getting sent as long as i am holding brake, as expected. but if the car is moving forward and i hold brake, the message is only sent once and the car doesn't brake.

hit is a variable name. You could call it foo or poop or rainbow for all that it matters. What you called hit is a ControllerColliderHit. So the docs that navarone sent are what you need to look at.
Of course it will not have the randomly chosen variable name in the docs.

[weak spruce]

Why spawn areas rotating

[leaden ice]

how should we know? Presumably due to your code.

[weak spruce]

https://hatebin.com/eklltgbzqt

here is code

[final valve]

wait i have another issue, idk wtf happened but by is my character rotating like this now

[lean sail]

Looks like your character isnt centered and you're rotating a parent object. But im just guessing since you didnt show relevant code. Also stuff like this really belongs in #💻┃code-beginner

[leaden ice]

your code is pretty explicitly rotating the spawn areas randomly

GameObject Sheep = Instantiate(sheep, SpawnPosition, transform.rotation = RandomRotation);```

transform.rotation = RandomRotation < this rotates the object the script is attached to

i.e. the spawn area

To spawn an object with a random rotation you would just do:

GameObject Sheep = Instantiate(sheep, SpawnPosition, RandomRotation);```
You have the extra `transform.rotation = ` in there which is causing your problem

[stable osprey]

Why not just MonoBehaviour.Update?

public abstract class MBPool<T> where T : MonoBehaviour, IPoolEntity  {
    protected Queue<T> pool = new Queue<T>();
    protected Transform poolParent;
    
    public virtual void Initialize(int maxAmount, T prefab) {
        poolParent = new GameObject($"{typeof(T).Name} pool").transform;

        for (int i = 0; i < maxAmount; i++) {
            var newObj = UnityEngine.Object.Instantiate(prefab, poolParent);

            newObj.OnSpawn += () => OnSpawn(newObj);
            newObj.OnDespawn += () => OnDespawn(newObj);

            OnEnqueue(newObj, i);
            pool.Enqueue(newObj);
        }
    }

    public virtual T GetNew() {
        if (pool.Count == 0) { return null; }
        var obj = pool.Dequeue();
        obj.OnSpawn?.Invoke();
        return obj;
    }

    protected virtual void OnEnqueue(T poolObj, int i) => poolObj.gameObject.SetActive(false);
    protected virtual void OnSpawn(T poolObj) => poolObj.gameObject.SetActive(true);
    protected virtual void OnDespawn(T poolObj) {
        poolObj.gameObject.SetActive(false);
        pool.Enqueue(poolObj);
    }
}

this doesn't handle automatically collecting despawned objects, but sounds like better architecture than having a manager for despawning objects

it's for a demo project I've done some years ago, here's an example usage for reference -- quite simple: https://github.com/Lyrcaxis/Hack-and-awesome/blob/main/Assets/Scripts/Utilities/EnemyPool.cs

(simple I mean the usage 😛 the contents may not be that simple lol)

np!

[lean sail]

https://docs-multiplayer.unity3d.com/netcode/current/advanced-topics/object-pooling/
The unity multiplayer docs also have a good setup for object pooling. You just change the networking stuff to like GameObject or Component. Whatever you want

Though regardless if you want to automatically return objects to the pool then ideally you have some timer, either on the pooled object or the pool itself keeps track of them all in a separate list

You can skip a lot of the beginning since it's very specific to unitys networking for game objects (NGO)

Make a panel and child a text component and... write some text? I dunno because you do not describe what you actually want at all.
Go to the #📲┃ui-ux channel and write a WAAAAAAAAAAAAAAAAAAAAYY more descriptive question.

this thanks came with an engagement proposal 😆

[glossy isle]

bro i sent photo
what is the problem

i want to add it in my game

but idk

just this

[rigid island]

instead of being lazy why not search it on youtube

why 😂

[glossy isle]

when i search i get msg box in pc windows

[glossy isle]

[stable osprey]

I mean -- what you posted is full-fledged multiplayer chatbox, it's unlikely to get it done simply by following a tutorial 😅

also the way you posted it was funny as heck lol

[spring creek]

There is a picture, but the words are even more vague then before. Tell us what you tried so far and why it didn't work

[rigid island]

why not actually adding Unity to the search terms..

[glossy isle]

i search but i can get response

[spring creek]

What?

[glossy isle]

😮 oo . i don't know bro

[glossy isle]

bot => but

[spring creek]

That does not make it any more clear

what does "I can get response" mean?

[glossy isle]

i can't get best answer

[spring creek]

Incorrect

[rigid island]

wrong

where do you think we get our answers from most of the time?

[glossy isle]

searching

google . youtube

[fallen lantern]

Hello everyone,I have been having a problem with a small project im working which is the top,bottom,right and left faces of this randomly generated cubes show up with distorted textures

I have been tinkering with it and I think I have probably made a mistake on how I make the triangles for the faces of how I give/assign the UVs
Here is some screenshots with how it looks in the editor and the code behind it

Could it be any of this 2?

[jovial valley]

For my game, I want to create an upgrade system in which I can change certain things about a tower and those changes will apply when i call Upgrade on a Monobehaviour, like how you can have overrides on a prefab variant. However, I dont want to reinstantiate the gameobject, is there a way to make it so that it will store the overrides of a prefab variant (or a functionally equivalent system), and allow me to change that based on changes when I upgrade?

[next quiver]

I am working on a vampire survivors like game. In the game, if you have a pistol in inventory, you start automatically shooting. If you have two pistols in the inventory, there should be two instances of these auto shots but I was not sure how to best implement this. Creating an actual new instance of the class wont work since its monobehavior.

[lean sail]

You can AddComponent if that's what you want, but I'd probably not use monobehaviour for these objects.

[lean sail]

You could do something similar to what LOD groups do. Have every single variant under a single gameobject then only set the one you want active.

[next quiver]

okay yea addcomponent would be a way to go about it, thanks. How would you instantiate the bullets without monobehavior?

[lean sail]

Instantiate is just a method, you dont have to call it from a monobehaviour

[tender gull]

another problem is rendering to texture

[potent anchor]

Starting a new project and marked my camera and player as DontDestroyOnLoad. In my second scene I have another player and camera object I use for building and testing, but when I play through the first scene and load the second, I was expecting to have duplicates (those in the second scene + the ones marked DND from the first scene)

But that's not happening. It looks like the DND gameobjects from the first scene are overwriting the gameObjects that I placed in the second scene

That's ...neat, but unexpected?

Does it work automatically that way now?

[lean sail]

Of course not, unity doesnt care if you have duplicate of a prefab. You must be destroying one of them at some point if they're not there in the hierarchy

[potent anchor]

so weird. thanks for the confirmation. I'll go find out where it's de-duping

[lean sail]

I'm gonna make a wild guess and say its in the same area you use DDOL probably because you made the player a singleton and destroy all other instances

[potent anchor]

yes

long day. Thanks

You should sell remote omniscient debugging services

[cosmic rain]

It's something you learn here after some time of helping people.

We can also see your project with a third eye and read your thoughts.

[lean sail]

👻 the error is on line 15

[potent anchor]

That's a really legit guess given that singleton code is generally up top

[minor stream]

hey so i need help making a game, im struggling to put my ideas into it and need help, i know it kinda seems a little jumpy but i could really use the help.

i have taken classes on coding with unity before but need some help with it

[cosmic rain]

What's the actual question?

[spring creek]

If you ask a specific question, someone may help
#854851968446365696

[minor stream]

yeah, im just trying to put it into words

So basically, i want a system where if the player hits the enemy every time the enemy and the player go up in the air, To put it like this
One hit would just launch the enemy backwords
Two hits would send you and the enemy upwords a little bit and then if their is no other button press, you both fall back down
Three hits would launch both of you up and the last hit would knock the eneny back

[spring creek]

So knockback

And what have you found online when you looked?

[minor stream]

kind of

lemme finish the text cause i accedently pressed enter early before i could finish what i was writing

lemme make a diagram

[cosmic rain]

Sounds simple enough if you keep track of the number of hits and apply force/velocity/movement accordingly.

[minor stream]

ive tried something like that

    private float distance;
    EnemyBehavior enemyBehavior;
    PlayerBehavior playerBehavior;
    EnemyAI enemyAI;
    public bool CanAttack;
    public bool DoubleAttack;
    private float LastClickTime;
    private const float DOUBLE_CLICK_TIME = .5f;
    void Start()
    {
        enemyBehavior = GameObject.FindGameObjectWithTag("Enemy").GetComponent<EnemyBehavior>();
        playerBehavior = GameObject.FindGameObjectWithTag("Player").GetComponent<PlayerBehavior>();
        enemyAI = GameObject.FindGameObjectWithTag("Enemy").GetComponent<EnemyAI>();
    }

    // Update is called once per frame
    void Update()
    {
        distance = Vector2.Distance(transform.position, Enemy.transform.position);
        if (distance <= 2)
        {
            CanAttack = true;
            if (Input.GetKeyDown(KeyCode.P))
            {
                if (PlatformGameManager._playerStamina.Stamina > 0)
                {
                    Debug.Log("Hit");
                    float timeSinceLastClick = Time.time - LastClickTime;

                    if (timeSinceLastClick <= DOUBLE_CLICK_TIME)
                    {

                        enemyAI.EnemyLaunchUp();
                        playerBehavior.PlayerLaunchUp();
                        enemyBehavior.EnemyTakeDmg(10);
                        playerBehavior.PlayerUseStamina(20);
                        DoubleAttack = true;
                    }
                    else
                    {
                        enemyAI.LaunchBack();
                        enemyBehavior.EnemyTakeDmg(5);
                        playerBehavior.PlayerUseStamina(10);
                        DoubleAttack = false;
                    }
                    LastClickTime = Time.time;

                }
            }

        }
        else
        {
            CanAttack = false;
        }
    } ```

[minor stream]

the problem i have with this code is 1, it doesn't launch up correctly and 2, it dosent go in the right direction

[cosmic rain]

Did you make any attempts at debugging it?

[minor stream]

yes

[cosmic rain]

And? What did you discover?

[minor stream]

nothing

idk if i debugged right though

hold up

[cosmic rain]

Debugging means finding the issue cause and potential fixes via various techniques, like logging, drawing debug info/gizmos, or stepping through the code with a debugger. If you didn't discover anything, then your debugging failed.

Or rather, you never completed the debugging.

[digital falcon]

How so?

[cosmic rain]

It might cause issues during the build due to file access rights.
Ideally, put your project close to the disk root.

[digital falcon]

disk root?

[spring creek]

C:/ is a disk root
D:/ is too

So something like C:/UnityProjects is always preferable

[digital falcon]

Ah

[jovial valley]

can I make it so that a certain ScriptableObject only appears when I rightclick a prefab, just like a prefab variant?

using UnityEngine;

[CreateAssetMenu(fileName = "New UpgradeAsset", menuName = "???")]
public class UpgradeAsset : ScriptableObject
{
public GameObject originalPrefab;
}

smth like that

and it stores the prefab I created it from in originalPrefab?

[soft shard]

Im not sure ive seen this use case before, ScriptableObjects are files that are stored in your project, a prefab can reference that file, though I dont see how restricting creating it to a specific prefab would help if it would create a file in your project that anything can reference anyway? Through the attribute alone there is no way to do that, AFAIK it would likely involve a custom editor window or editor script - what might be the end goal of such a system? Why is this specific scriptable object unique to only one specific prefab in your project?

[jovial valley]

Well basicaslly

i want to create a very flexible upgrade system for prefabs

where I can change like everything about them, similair to how a prefab variant works. Right now, ive been trying to figure out how to hijack prefab variants for htis use case, but I was exploring the possibility of creating my own custom asset to work better.

[soft shard]

Ah I see, there are likely other ways but one that comes to mind is possibly using generics, interfaces and inheritance to create "variants" with different logic and public variables, it could help to maybe plot out a set of what your variants could look like, what needs to change between them and how you intend to use or reference those changes, for example you could use a serialization library like Newtonsoft JSON and use text files instead of ScriptableObjects, depending on the depth of your system and how you intend to use them, both would have a different process for actually populating and making copies of your data though (although a ScriptableObject is also basically a fancy YAML text file that Unity serializes)

[hot sorrel]

hey if there are multiple references to the same instance of a custom non-unityobject on multiple classes that needs to be serialized is it a better idea to use serializefield or serializereference

[spark vigil]

Depends on the behavior you want. Is it important that they all reference exactly the same object?

If not, it doesn't really matter. SerializeReference may give you smaller data size I suppose

[hot sorrel]

yeah i expect to have 6+ different things referencing the same object

[hard estuary]

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

You might want to serialize as a reference rather than a value when:
You want multiple references to the same instance of a custom serializable class.

[little meadow]

I feel like the answer is SctiptableObject... or it doesn't matter... but oh well 🤷‍♂️

[frigid turtle]

Hello there guys! How to disable creation and uploading symbols.zip for Android build?

i did some research and found almost nothing about it

[little meadow]

It's in the build settings, no? There's a dropdown for them symbols

[frigid turtle]

yeah, i forgot to say my build starts through command line or something like this, and idk where the person who responsible for this solution

[little meadow]

is it an automatic build thing? it still probably uses whatever settings the project is with, so you can change from the same place and push 🤷‍♂️

There is EditorUserBuildSettings.androidCreateSymbols if you need to change it from code, I guess 🤷‍♂️

[oblique spoke]

There's probably a script in the Unity project being invoked by the build script. Check to make sure if it's overriding any settings

[frigid turtle]

oh thanks, ill check both options

[frigid turtle]

right, i found one, but no code working with symbols in there unfortunately

anyway thanks

[edgy stump]

How I can build game with script?

I mean, when I run.exe file, and in the game I press the button called "Build", it should be build game for windows

[frigid turtle]

if you mean from C# script then it should be like BuildPipeline.BuildPlayer()

[edgy stump]

using UnityEngine;

public class BuildScript
{
    public static void BuildGame()
    {
        string[] scenes = { "Assets/Scenes/Scene1.unity" };
        string buildPath = "C:\\Users\\Admin\\Desktop\\MyGame.exe";

        BuildPipeline.BuildPlayer(scenes, buildPath, BuildTarget.StandaloneWindows64, BuildOptions.None);
    }
}

Like this?

[frigid turtle]

yeah, doesn't it work?)

[edgy stump]

Here's other script:

using UnityEngine.UI;

public class BuildButton : MonoBehaviour
{
    public Button buildButton;

    void Start()
    {
        buildButton.onClick.AddListener(OnBuildButtonClicked);
    }

    void OnBuildButtonClicked()
    {
        #if UNITY_EDITOR
        BuildScript.BuildGame();
        #endif
    }
}

[frigid turtle]

oh right, it's only from editor so i think you cant run it in the game)

[edgy stump]

Can I use resources folder?

Yeah, I'm dumbass

[frigid turtle]

dont remember

[little meadow]

obviously the build script should be in editor folder or entirely #if UNITY_EDITOR'd

[edgy stump]

So, it's woking only in editor?

[little meadow]

I mean... it's the editor that is building the game... where else would you want it?

[frigid turtle]

sorry but i really dont remember this)) try to google it or ask gpt

[edgy stump]

I want to build the game INSIDE the game

[little meadow]

you can't... but also am curoious for the use-case

[frigid turtle]

you may run like bash script or kinda from your game

[oblique spoke]

Only editor can build. You can tell your editor install to start a build from a game though.

[frigid turtle]

@edgy stump

i think it should be like this

[edgy stump]

Bat File?

[frigid turtle]

yep

so you need to get access to this file and run it

[edgy stump]

I have to run it through a script?

[edgy stump]

Okay

thank you

[frigid turtle]

np

[edgy stump]

But I still have one more little question

[oblique spoke]

You can start the process from C# too

[frigid turtle]

i hope it works)

[edgy stump]

What if this game is on Android?

[frigid turtle]

oh it may be significantly harder to run if not even imposible)

[oblique spoke]

Then you first need to connect to a device that is capable of running the editor

[frigid turtle]

actually imposible))) it's android, you dont have an editor on a device

[wide lily]

☝️

[little meadow]

did we discuss the use-case?

this seems super weird to me... I'd think there's a better way of doing whatever, unless it's really super specific

[frigid turtle]

no, still very interesting))

[lean sail]

This doesnt really look related to what you're asking above. You should say what the actual use case for this is, what game mechanic are you trying to create?

[edgy stump]

Game building system

[lean sail]

i really dont feel like playing 20 questions to get more information. It sounds like you're trying to make an app which can create games? You simply arent gonna be building a game from an android app.

[tribal jay]

hey, when i want to restart my game in singleplayer i just call SceneManager load scene and it restart the game, but i unity netcode when i want to do the same thing it doesnt restart the game when using Networkmanager.SceneManager.Load. What am i doint wrong?

[edgy stump]

Yes

                if (validVectors.Count > 0)
                {
                    Vector3 averageDirection = Vector3.zero;

                    foreach (var vector in validVectors)
                    {
                        averageDirection += vector;
                    }

                    averageDirection /= validVectors.Count;
                    vectorField[current] = averageDirection.normalized;
                }```

right now im calculating the vector of my resistance field by taking the avarage. but it should point into the avarage of the lowest resistances. how could i make the lower resistances weigh more than the higher ones?

[steady moat]

How about something like that ?

float average = 0;
var elementWeightNormalizeds = elements.normalizeWeight();
foreach element in elementWeightNormalizeds 
  average += element.value * element.weight

[(0.5,0.7), (3, 2), (1, 1.5)]
float weightSum = 0.5 + 3 + 1 = 4.5
[(0.11,0.7), (0.66, 2), (0.22, 1.5)]

average = 0.11 * 0.7 + 0.66 * 2 + 0.22 * 1.5 = 1.727

A more performant way would be:

average = (0.5 / 4.5) * 0.7 + (3 / 4.5) * 2 + (1 / 4.5) * 1.5 = 1.727

[static matrix]

fellas I think I mistyped something

[bright relic]

i'm trying to understand what you wrote but im having trouble wrapping my head around it😅

[rigid island]

what is gameRunner and why are you trying to assign a class to it 🤔

classes are just blueprints to objects

[static matrix]

gamerunner is the static instance of this class (GameRunner)
I mistyped "this" and it corrected to "ThaiBuddhistCalendar" which I thought was hilarious

thanks ill check that out

[glossy trench]

If I'm to understand this correctly, if I'd like to use Scriptable Objects to save data for my character creator.. would it be best if the data while it's 'hot/live' is kept as a JSON in memory - then once the character is finished, create a new instance of the SO we'd based this JSON off of initially, populate it with data from this JSON, then save this new SO asset to the disk?

Sorry if I'm wording it vaguely lmao, just want to know if this is how it should be done

[steady moat]

As long it is not runtime save.

ScriptableObject is not made to save data from runtime.

[glossy trench]

Okay, so it's more for when you have static data you'd like to 'plug in'

[steady moat]

Immutable data.

[cold parrot]

yes, if you make that data runtime-mutable, you will shoot yourself in the foot.

[glossy trench]

Would using it for a game save then, where I'm instantiating a new SO asset, not be recommended?

[vivid wave]

Yo

[cold parrot]

no, not recommended

[vivid wave]

Can I make a ticket?

[cold parrot]

no

[vivid wave]

Okay

[cold parrot]

you can use an SO as a reference to, or container for, a configuration for a game-save/load mechanism

you can even put a reference to that game state which you want to save/load into your SO if you really want that.

but that would be more or less the same as a global static variable, and that generally is not a great thing to have.

[glossy trench]

Oh okay, that makes sense!

[cold parrot]

regadless many simple games use a global game state object successfully. Its up to you how to make that accessible and how to mitigate the issues it brings. Piping it through an SO is one of the options,

[glossy trench]

So I could use the structure of that SO and have my game saves as actual JSONs without a hitch in the future as my project gets increasingly complex? (lmao open-ended question)

[cold parrot]

its irrelevant that its an SO

you have a global state object and everything in your game will be coupled to that object's structure

[glossy trench]

Trying to understand this. A class would serve the exact same purpose and structure, right?

[cold parrot]

if you expect a complex data model and worry about maintainability, you could inject objects only with a small portion of that gamestate (through an interface), effectively reducing the surface area of the coupling

[cold parrot]

yes

a SO is just an instance of a class that is automatically created on application start and gets its public (serializable) fields filled with static configuration you defined when editing the game in the unity editor.

[glossy trench]

OH

Coughs in not going through the unity tutorials

[cold parrot]

an SO solves the problem of "where do i put my static configuration" for unity projects

you could also look at them as custom asset types

[glossy trench]

So, having the options as an SO itself would be pointless since we're going to be messing with it at runtime anyways?

Braining: If I'm to have a bunch of SOs in a folder, let's say it's uhh.. Graphics Presets. We're never going to change those at runtime, and we can reference them easily like they're just a convenient data container. Like any other static object. However I choose to store my actually runtime-modifiable settings data, it's all good for me to reference those SO assets?

I hope I understand now what they're actually for. I was using them like this before, but got caught up in figuring out how to save a bunch of characters. I'm going to check out custom assets now based on the advice.

[uneven slate]

Unity documentation is shit. what do I use to raycast from a position & direction in worldspace, to hit a canvas, in worldspace.

[leaden ice]

What are you trying to achieve exactly?

performing a raycast yourself is not necessarily the right approach

Physics raycast (probably what you were looking at) is only for physics colliders, not UI.

[static matrix]

Physics.Raycast
and if you are really feeling funky you could put a collider on your ui

[uneven slate]

I'm trying to raycast from a position and direction in worldspace, to see if that ray hits a canvas within a set distance.

I'm aware physics raycast doesn't hit it. I'm trying to figure out what raycast does hit it.

[leaden ice]

why are you trying to raycast though

what's the actual goal

what are you trying to achieve.

There's a better way to do it probably

[uneven slate]

To know if the ray is hitting a canvas. Internal logic. XR shit.

[static matrix]

normal raycast should hit it if the canvas has a collider

[leaden ice]

This is what the graphic raycaster is for

but also - generally you would just use the event system directly

if you're trying to do UI interaction

[uneven slate]

I'm not trying to do interaction, I'm trying to see if an arbitrary point in space, with an arbitrary direction, and an aribtrary distance, would cast a ray that hits a UI element, whether that UI element is on screen or not does not matter in the least. it's not for interaction. it is just for seeing if a point would hit a canvas.

[leaden ice]

GraphicRaycaster:

https://docs.unity3d.com/Packages/com.unity.ugui@3.0/api/UnityEngine.UI.GraphicRaycaster.html#UnityEngine_UI_GraphicRaycaster_Raycast_UnityEngine_EventSystems_PointerEventData_System_Collections_Generic_List_UnityEngine_EventSystems_RaycastResult__

[turbid silo]

I do not know if this is here that I have to ask some questions for help but here an "issue" I met by attempting curiosity test.

It's a little question that may take only a minute to answer but I can't find the answer whether by using Unity Docs, GPT or VS Intellisence built-in feature :

// Enable the input actions
playerInputActions.Test.Enable();

// Subscribe to the different phases of the action
playerInputActions.Test.Press.started += OnPress;
playerInputActions.Test.Press.performed += OnPress;
playerInputActions.Test.Press.canceled += OnPress;

I have this code, is it possible to compact all of those subscription to my action phases ? Like is there a keyword allowing me to trigger OnPress() whenever it's started, performed or canceled ? All of that without having to have three subscription so.

[leaden ice]

no but you could write a quick helper function:

public static void SubscribeAll(InputAction a, Action<InputAction.CallbackContext> listener) {
  a.started += listener;
  a.performed += listener;
  a.canceled += listener;
}```

[uneven slate]

Graphic Raycaster lives on the canvas, as opposed to an arbitrary point, right?

[leaden ice]

Then use it as such:

SubscribeAll(playerInputActions.Test.Press, Onpress);```

[leaden ice]

Yes it lives on the canvas

and needs to have the event camera assigned

[turbid silo]

Hé, that isn't that dumb ! I have a question though, why is there "Action<InputAction.CallbackContext>" for the listener ? I'm supposed to only use the name of the method so for instance, I'll use "OnPress", no ? Why using CallbackContext then ?

[leaden ice]

Action<InputAction.CallbackContext> is the delegate type for all those events already

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.10/api/UnityEngine.InputSystem.InputAction.html#events

I'm not really sure I understand the question.

[turbid silo]

Yes but why using it for the method that is called whenever the context is the right one ?

[leaden ice]

I don't undestand what this question means

[uneven slate]

So there's seriously no way without putting a camera on the arbitrary points I want to check for UI? Unless the camera doesn't actually do anything, the implication is that it wouldn't work if the camera was for example pointing in a completely unrelated direction, so I can't just reuse the main one.

[knotty sun]

what is the method signature of Onpress?

[turbid silo]

Why using Action<InputAction.CallbackContext> to talk about the "Listener" while the "Listener" is basically a method I want to call ?

[leaden ice]

It's the delegate type

it means "a function that takes a InputAction.CallbackContext parameter and returns void"

[turbid silo]

public void OnPress(InputAction.CallbackContext context) {}

[leaden ice]

yes

exactly

see how your function has that parameter?

[turbid silo]

Ah I see

[turbid silo]

Hmm hmm ?

[leaden ice]

that's what the delegate type is enforcing

[turbid silo]

Oh

[knotty sun]

ok, now do you see the relationship?

[turbid silo]

So basically, it want to check if the function I'm calling have indeed this paramater ?

[leaden ice]

You are only allowed to subscribe such functions to those events

[turbid silo]

Understandable.

[leaden ice]

See what happens if you try a function without that parameter

it will give you an error

[zinc parrot]

so in my unity asset/plugin I distribute to others I have an xml file that holds material information
The users who download this plugin can add to this xml file
But when I distribute an update and they import the updated package, if they forget to disable the importing of the material xml from the package, all their changes get overwritten and deleted
is there a way around this to disable it automitically if the file already exists?

[knotty sun]

why not just move the file to a different folder after import?

[zinc parrot]

when the updated package gets imported, itll overwrite it seemingly no matter what resources folder it is in

[knotty sun]

not if you move the file and delete the original .meta file

[zinc parrot]

but it needs to be loaded through resources.load

so it needs to be in a resources folder, which unity will automatically create a .meta for

[knotty sun]

you misunderstand me
original in Resources
after import move file to Resources/Loaded
delete original .meta file
unity will create a new .meta for the moved file
then you can check if the Resources/Loaded file exists or not and not overwrite it if it does

include an asset postprocessor script in your package

[zinc parrot]

ohhh!!!
so thisll let me decide during import whether or not to import specifical files?

oh wait no

ok I think I understand

[knotty sun]

no, it will still import the original into Resources but will allow you to decide what to do with it

[zinc parrot]

@spring creek Sorry, I guess my question was a bit unclear, I am using Rider with Unity, I'm referring to AI tools/workflows in that context.

[spring creek]

Oh. I dunno if copilot works with rider. But I would guess it does.

I think the proper channel for that kind of question is #1157336089242112090

Honestly, I try to avoid ai since it is 9/10 times garbage, so I don't know

[spring creek]

Not a code question. I guess #🏃┃animation makes the most sense. Or #💻┃unity-talk

[spiral bridge]

Not ChatGPT specifically, but you can look into Github Copilot, it has a Rider plugin that supports both inline suggestions and chat. I haven't personally used the chat part, so not sure how good it is, but the inline suggestions are generally pretty good.

[spring creek]

Yeah, I was thinking copilot would be the only one. Glad to hear confirmation about support

[compact spire]

I was hoping to try something like Cody, but it's not available for Rider

Rider also has AI assistant, which is Jetbrains own

I'm sure there are other extensions as well

[spiral bridge]

Sorry, I am trying to get this in code, should I still move the question to #🏃┃animation?

[compact spire]

Maybe those are my only 2 options

[spring creek]

They can help with code as well yes. Since it is code, it would be fine in either, but people with more knowledge in animation hang out in the #🏃┃animation channel.

Your choice

[spiral bridge]

I'll try there too, thanks

[compact spire]

From what I read copilot is better than AI Assistant

but I also found Cody does have a plugin for Rider

So I will give that a shot

Hello everyone, I'm looking to achieve some kind of limb removal in a Kenshi like way, do anyone has any insight on propers way to achieve this?

[zealous bridge]

I have untracked changes and I do git reset --hard HEAD but those untracked changes are still there. Internet says that is probably has to do something with line endings and git automatically changing them on checkout or commit. I attached my .gitattributes. Is it incorrect? it doesn't contain "crlf" anywhere. I have empty unity project and don't know when is .gitattributes necessary so I add it from the beginning. Is it wrong practice?

[thorn crag]

if i set time.timeScale to 0, and then tried to recolor an object, would the object be able to be recolored?

[spring creek]

Have you tried it and it didn't work

Were you perhaps using deltaTime to smoothly change it? DeltaTime will of course be 0 when timeScale is 0

[thorn crag]

i have been trying to change the color of a ui element in my pause menu, but in editor game mode, it keeps its color set to 255, 255, 255, even if the code says that it's color is different

[spring creek]

Ok, are you:
A) changing it in Update? Update will not be called when timeScale is 0
B) using deltaTime as I asked?

[thorn crag]

the change is supposed to be instant, and yes, i am using update

[spring creek]

Ok. Update is the reason it is not working

Callbacks like OnClick will still be called 🤷‍♂️

Could call it BEFORE setting timeScale to 0 too, if possible

[thorn crag]

but there is other code in update that is being called like normal, and it will still force the value 255, 255, 255 even if i change it in the inspector

[spring creek]

Hmm. Then you have other code setting the value somewhere

You should probably just show the code of course

Oh, are you using Color or Color32 in code?

[thorn crag]

Color

[spring creek]

Then it is only values of 0 to 1

If you set it to 1,1,1,1 or anything greater that is the same as 255,255,255,255 in the editor

[thorn crag]

i changed it to Color32 and it works now!

thank you :)

[raven basalt]

I tried importing an animation from blender to unity, but the scaling of the animation doesn't work, even though the rotation and the location of the animation works. Anyone know how to fix this?

[little meadow]

I have to annoyingly point out that Update will be called when timescale is 0, for future reference 😋

[spring creek]

No not at all. I realized that afterwards, but that is a very good thing to point out.

I've been away from unity so long I keep forgetting things

[little meadow]

FixedUpdate won't be called as it does require some time passing in the simulation

[subtle spoke]

After some more investigation, this is what I have happening:

UNITY_EDITOR_WIN and UNITY_STANDALONE_WIN both work in scripts written in unity. it determines it to be true
Neither work in a C# file I made in Visual Studio and imported into Unity via DLL. In fact, when I removed those IF statements, it gives me an error saying that it is "Unable to resolve reference 'Windows.Foundation.UniversalApiContract'"

This is probably an issue on VS's end. How can I resolve this error and make Bluetooth LE able to work in Unity?

[somber nacelle]

Neither work in a C# file I made in Visual Studio and imported into Unity via DLL
this is to be expected. those preprocessor directives determine what gets compiled, if those symbols are not defined, then the code they encompass will not be compiled at all into the DLL

[subtle spoke]

Just tested ENABLE_WINMD_SUPPORT and UNITY_WSA, both fail

[wide terrace]

Just to elaborate a bit further, they're interpreted immediately prior to compilation. They don't exist at the time of compilation nor in build artifacts/output.

[subtle spoke]

I see. how can I fix this and allow Windows API to be run in Unity??

[somber nacelle]

do you have the relevant DLLs in your project?

[subtle spoke]

Yes, they are in my VS project
Not in Unity, because i'm not sure which are the relevant DLLs (I'm trying to use the Windows.Devices.Bluetooth and Windows.Devices.Enumeration) DLLs

@somber nacelle

[somber nacelle]

i am referring to your unity project. do you have the DLLs you are trying to use in your unity project, because if not then naturally you won't be able to use them in your unity project

[chilly surge]

#if are preprocessor directives, they take effect during compilation, and so they have already taken effect when you compile your code to the .dll.

[subtle spoke]

no, because I don't know which are the relevant dlls (not sure where to find that info after googling for it and failing to find it)

I'm trying to use the Windows.Devices.Bluetooth and Windows.Devices.Enumeration

[somber nacelle]

well you'll need to figure out what DLLs you need and add them to your project

[subtle spoke]

I think it might be system.runtime.dll, system.runtime.windowsruntime.dll, and system.runtime.interopservices.windowsruntime.dll

let me try that, I'll get back to you if it works/doesn't work

It says "unable to resolve reference windows"

let me check how to solve that

yeah there aren't really any ways to fix that online

yeah after adding system.windows it still insists that its unable to resolve reference windows

[chilly surge]

Adding to where, Unity?

[subtle spoke]

yeah

Just also tried to use the windows api

it says

The type or namespace name Devices does not exist in the namespace Windows

[cosmic rain]

"Unity includes Windows Runtime support for IL2CPP
on Universal Windows Platform
platform."
https://docs.unity3d.com/Manual/IL2CPP-WindowsRuntimeSupport.html
That API is part of the windows sdk, which unity needs to incorporate into the build. And it only does it in UWP builds.

[subtle spoke]

swapping to il2cpp changed nothing (I am on .NET Framework). I keep seeing sources saying that Unity would automaticlly enable UWP when I switch to il2cpp, but it never works. Not sure how to incorporate the windows sdk into the build either. Can you help me enable it?

[late lion]

You have to switch to this build platform if you want to access WinRT APIs.

It's not possible to access in a regular Windows Standalone build.

[subtle spoke]

Using this platform, do I have to build it to run it correctly? or does it work in testing as well?

like if I click the normal unity run button, can it access the functions?

like Windows APi

[late lion]

You have to build. The editor doesn't run under the Windows Runtime.

[subtle spoke]

oh

[broken light]

has unity put the navmesh obstacle code up on github? i need to modify it to support custom polygon shapes

[iron vortex]

If I have a public abstract class that inherits from MonoBehavior, how might I pass a reference to this class to a subclass that inherits from the abstract class?

[leaden ice]

There's nothing special about passing such references around, but it's potentially weird that you want to.

What's the use case?

What are you trying to accomplish?

note also that you generally don't deal with references to classes. You are generally dealing with references to instances of a class.

[iron vortex]

I have a MonoBehavior method that I need to call but can only pull a MonoBehavior reference from a parent class

or, well, if there's another way idk

[somber nacelle]

can you be more specific about what you mean by that?

[iron vortex]

Sure I can even provide you samples

hang on just a second

[leaden ice]

I really don't get what you mean by this yeah

show the code

if your class derives from MonoBehaviour you needn't do anything special

If you have A : B and B : MonoBehaviour then any reference of type A OR B will also have everything in MonoBehaviour

[iron vortex]

The MonoBehavior class:

public abstract class Interactable : MonoBehaviour
{
    // Message displayed to player when looking at an interactable.
    public string promptMessage;

    // This function will be called from our player.
    public void BaseInteract()
    {
        Interact();
    }
    protected virtual void Interact()
    {
        // We won't have any code written in this function.
        // It's a template function to be overridden by subclasses.
    }
}

public class EventInspect : Interactable
{
    protected override void Interact()
    {
        Debug.Log("Interaction (" + gameObject.name + ")");
        // StartCoroutine(DelayCall);
        }

        IEnumerator DelayCall()
        {
            yield return new WaitForSeconds(1.5f);

            // stuff to execute with a delay
        }
}```

[naive swallow]

You have a function in your function

[leaden ice]

ok so what's the problem?

[leaden ice]

nah just poor indentation

[naive swallow]

Ah, you're right

Nevermind that's fine

[iron vortex]

It doesn't like trying to call a MonoBehavior method

[naive swallow]

What do you mean "it doesn't like" it

[leaden ice]

what doesn't like it? What did you try and what happened?

[somber nacelle]

it should work just fine, since this inherits from a class that inherits MonoBehaviour (unless you haven't saved both files or something so unity doesn't see that the abstract class inherits MB)

[iron vortex]

I just need to know what the right syntax is for it

[leaden ice]

It should be:

StartCoroutine(DelayCall());```
Is that your problem? That has nothing to do with abstract classes or inheritance or anything, you just forgot the ().

[naive swallow]

The right syntax is uncommenting your StartCoroutine line

[iron vortex]

that's it?

[leaden ice]

that's it

[iron vortex]

it just doesn't need parentheses?

[leaden ice]

it DOES need parens

[somber nacelle]

it does need them

[leaden ice]

look at my example

you don't have them in your commented code

[naive swallow]

Opposite

[leaden ice]

You jumped to a lot of conclusions about inheritance etc 😵‍💫

[iron vortex]

Hold and I'll update you, also sorry if I worded it weird

[somber nacelle]

also not super important, but you can start a local method coroutine just fine provided you aren't using the string overload for StartCoroutine

[leaden ice]

In the future instead of saying "it doesn't like it", sharing the actual code and the actual full error message you get would be a lot more useful and get us to a solution much more quickly.

[iron vortex]

See I would have, and that was my bad, it's just I had refactored the code a lot afterwards so I no longer have the reproducible broken code

[leaden ice]

It was probably saying "DelayCall is a method group which is not valid here"

something like that

[iron vortex]

Ah yeah I'd say so, anyways that worked, thanks a bunch

[versed marsh]

Is there no way to normalize a Vector2Int?

[rigid island]

make into a vector2 then make it back?

[versed marsh]

yeah ill try that

[late lion]

What do you consider to be normalized? With Vector2, it means the magnitude is 1. But there are only for possible vectors of magnitude 1 with Vector2Int: up, down, left and right.

[rigid island]

Ig cause it would not make sense since you will lose precision anyway since its 1 max

[spring creek]

Yes, what would the result of normalizing a vector2int with 1,1,0 be?

[dusk apex]

Never mind, the normal would be the perpendicular/orthogonal (-1,-1)

[spring creek]

Wait what?

Also, I just realized I used three values for a v2 🤦‍♂️

[dusk apex]

Ah, I had posted something about unit vector prior to the above but deleted - a unity normalized vector would be a unit vector.

[cunning burrow]

I have a quick question, would there be a way to create a mask on a UI using a game object? or something of the likes?
I want to create maybe one big red UI on the screen and mask it with a big circle object centered on my screen, and then when the player zooms out it could like show as a enemy area

or would there be a better way to do it?

[spring creek]

Ok, but then they want it as a Vector2Int. So that is the part that I wouldn't understand

[swift falcon]

Is it not a correct way to make an object move on a speed with the direction being its "forward"?

transform.Translate(new Vector3((float) Math.Cos(transform.eulerAngles.z * (Math.PI / 180) + Math.PI / 2) * speedCurrent * Time.deltaTime, (float) Math.Sin(transform.eulerAngles.z * (Math.PI / 180) + Math.PI / 2) * speedCurrent * Time.deltaTime));```

When I do this, the object does not move forward along its axis

Help is appreciated

Note that the + Math.Pi / 2 is there so I can have the capsule move on its proper axis

[wide dock]

Why all that math

transform.up

[swift falcon]

Mhhh

[wide dock]

or transform.forward, forgot which one it was

[swift falcon]

I am coming from another language so I may need to get my bearings again 😅

Yeah the normal I want is up

I forgot Unity does that

[wide dock]

Yep, so just use that

[swift falcon]

Well thank you

I just kind of hate that the Euler angles are deg though

It still happens however, when I rotate the object I do it properly do I not?

transform.Rotate(Vector3.forward * -(float)10 * Time.deltaTime);```

It is for a 2D game

transform.Translate(transform.up * speedCurrent * Time.deltaTime);```
My messy math simplified

At this point I am quite confsed

Maybe my camera got messed up

But no though...

Okay let me be more specific, the problem is that the object moves along an axis that rotates faster than when you rotate visually

Say at 0 rad the object moves up, at -Pi/4 the object moves right and at -Pi / 2 the object is already mvoing down

There is a 1:2 ratio so to speak

[little meadow]

Translate has a parameter for whether the vector you pass is in world or local space... by default it's local (I think), so you need to adjust the vector you pass, or tell the function it's a world space vector

[swift falcon]

How curious

[little meadow]

you can either do Translate(transform.up, world), or Translate(vector3.up, local)

[swift falcon]

Ralativity got it

Problem appears to be Solved ✅

the solution was the following

transform.Translate(transform.up * speedCurrent * Time.deltaTime, Space.World); //Space world makes it so the object moves accordingly

Thank you ❤️

[little meadow]

That comment is extra weird

[swift falcon]

Oh?

[little meadow]

Space.World makes it so that the vector you pass is a direction in world space

[swift falcon]

Yeah I miscommunicate that

Okay

Neat

[little meadow]

so, yeah, always a good idea to keep in mind what vector is in what coordinate space

[swift falcon]

Well every engines has its quirks, it is a consideration I failed to have

[little meadow]

yeah, yeah, that is true for Translate's params, but the geometry thing is the same for all of them, hence why it's good to keep in mind 😛

[swift falcon]

I see 😄

[deft meadow]

Hi, I'm currently trying to make a grappling hook esc mechanic. Does someone know of a good tutorial for this?

[lean sail]

there are many tutorials on google, but at the end of the day you're gonna need to make it unique for your game
Maybe specify what you actually want. Because right now it just sounds like you wanna move the player in a direction, which isnt really something hard.

[civic folio]

if I use the new keyword on something does it get garbage collected or I have to delete it myself?

[deft meadow]

I want the player to be able to click a point and than be able to swing from that spot and move up and down the rope connected between the player and the grappled spot.

[knotty sun]

generally in C# you never have to dispose yourself

[leaden ice]

Whether you use new on it or not isn't really a determinator of that

Things you have to call Destroy on are UnityEngine.Object derived classes.

[civic folio]

I don't really get heap and stack

[leaden ice]

There are also things that are IDisposable that need disposing manually

[leaden ice]

It has nothing to do with manual cleanup

Classes get allocated on the heap

Structs don't except as members of classes

[cosmic rain]

Heap is basically where memory for reference types is allocated(including whatever data they store in them, even if it's value types). Stack is for value types that are allocated during methods execution, basically in the call stack.

[lean sail]

have you tried to create anything related to this? again there are definitely tutorials out there for grappling hooks. The only thing that really changes is how you're moving the character, either by rigidbody, character controller or some kinematic character controller.

[deft meadow]

I haven't written any code myself yet, since I first wanted to understand what the basics were, but I can for sure give it a try

[spring creek]

As I said, do that in #🏃┃animation

[flint needle]

Whats the recommended way to modify Unity Packages so they are not treated as cache libraries?

Im modifying a URP shader from Unity repository but it warns changes will be deleted since it belongs to Package Cache

[knotty sun]

copy it to your assets folder

[flint needle]

Its not letting me move it, should i literally copy it?

[knotty sun]

yes

[leaden ice]

https://docs.unity3d.com/Manual/upm-embed.html

It should be copied to the packages folder

To turn it into an embedded package

[flint needle]

Its on the packages folder in fact

[leaden ice]

Yeah but actually there or you just mean showing in the unity project window

[flint needle]

Oh right

[leaden ice]

Follow the instructions in the link for copying it from the package cache

[flint needle]

Neat, thank you

When it says that cached packages are immutable, when are they reverted exactly?

[leaden ice]

Whenever it's least convenient in my experience 😂

No idea, probably whenever the unity process detects a change, through file watchers?

[flint needle]

im grateful that rider popped a warning saying to watch out when i started editing, it would be catastrophic to lose progress

[tender jolt]

I think I posted in the wrong channel, anyways, some now how to get the angle difference in relation to pitch direction in Unity using vector3.signedAngle?

[leaden ice]

SignedAngle is the way to go. Just plug in the appropriate parameters.

I.e. the two angles you want to compare and the normal of the plane on which you want to compare them

[broken light]

if i have an object that has no mesh but has visuals using Graphics API how can i check if its in the camera view to avoid calling draw mesh when not needed

[leaden ice]

[jovial valley]

Can someone help me with writing a script which finds all of the overrides of a Prefab Variant (or a gameobject in prefab form), and applies them to an instance of the base prefab?

Im trying to make an upgrade system which is very flexible, and this is what I want to accomplish, but what I am doing so far seems to not be working.

[knotty sun]

that sounds like a really, really bad idea

[jovial valley]

hm. is there a better way to achieve an upgrade system like this?

[gray mural]

Do you understand there are going to be conflicts?

[knotty sun]

you do realise that prefabs can only be modified in the editor not at runtime

[jovial valley]

the issue is that I WOULD reinstantiate the gameobject for upgrades, but some things like rotation, and other things can reference the tower, (even other upgrades), I want to stay on so it basically needs to keep changes. As such, I sort of want to log every change an upgrade makes and apply those changes on an upgrade and only those changes.

thats not the point - My goal is to basically make a folder which contains prefab variants which are upgrades of the prefab, then loop through and store all of the differences of the prefab varaints in something like a Scriptable Object, and then create a script which allows me to apply those differences to instantiated forms of that prefab at runtime.

[gray mural]

You want to be able to update a prefab at runtime?

[spring creek]

Why prefab variants instead of just changing yhe data?

[static matrix]

how can I get the length of an enum?

[gray mural]

Open your browser and type "c# enum length"

[jovial valley]

I would even create my own asset type for this, but idk how to do that, it just seems to me that a prefab variant holds all of the differences of it automatically, so thats what I aimed to use for this

[spring creek]

https://stackoverflow.com/questions/856154/total-number-of-items-defined-in-an-enum#856165
First result, unchecked

[static matrix]

sorry
should have goog'd first

[gray mural]

Well, it has 600 upvotes, so, probably, checked

[gray mural]

As was previously mentioned, modify the data

[jovial valley]

No, there would be a prefab, it would be instantiated somewhere in the world, and then I would call Upgrade() on a script in it and it would loop through and see if It can apply the changes that a prefab variant had onto the isntantiated gameobject, then do that

ok ok, so how do I store data changes without using a prefab variant?

[gray mural]

You... do use a prefab variant

[spring creek]

I meant by me haha. Did not open the link

[jovial valley]

ok that was my idea

[gray mural]

Which was fine and doable

[jovial valley]

alright, i guess im on the right track then

[gray mural]

Sure, just don't try to modify the original prefab

[jovial valley]

that was never the goal lol

[gray mural]

and applies them to an instance of the base prefab

That's what you have previously mentioned
