btw everything is more clear now thank you all!

yeah the levels are just to tell what its coming. So yeah, i'd keep the scriptable objects

most studios build custom tools to sync their data in an office-local model that everyone can access and back up to with infinite undos (like source control, sometimes it even is just source control)... They use custom tools to automate packaging everything and custom tools for initializing and serializing levels that are compatible with AAA practices for the purpose of compression and optimized load speed for target devices and for mass distribution....

In the end if you're just indie whatever you use doesn't matter :D if it works for you

2d right

Is there a way, to get a type and let a class accept is as so?

System.Type type = currentClass.GetType();
Singleton<type>.Instance.SendMessage(currentMethod);

Is giving me currently 'type is a variable but used as a Type'

//disable the collisions between you and ALL the enemies, not only the one who hurt you
}

MonoScript.Getclass itself is part of UnityEditor, so cant use that to call the methods from the runtim Instances

thick terrace
#

which part are you trying to do at runtime then?

#

none of the MonoScript stuff will work in a build

hexed pecan
#

The whole monoscript class is editor only

plucky inlet
#

So I am passing in the asset to the editor script, which holds the method string to call for. What I now need is the string to the actual class type, so I can once at runtime get the instance and call the methods from there

Is it possible to set custom mesh renderer bounds? The docs say that the field MeshRenderer.bounds cannot be overwritten, at least in 2019.3

so like Type.GetType?

plucky inlet
#

In the end, I had this more or less hardcoded

Singleton<XRAdminManager>.Instance.SendMessage(currentMethod);

And I want this method to get the dynamic XRAdminManager from the object I stored when assigning the monoscript in editor

#

Its just personal preference of dynamic code. If its not working at all, I just use a simple switch case

iirc if you store the full name of a type from the editor reference (https://learn.microsoft.com/en-us/dotnet/api/system.type.assemblyqualifiedname?view=net-8.0#system-type-assemblyqualifiedname) you should be able to fetch it at runtime with GetType

Type.AssemblyQualifiedName Property (System)

Gets the assembly-qualified name of the type, which includes the name of the assembly from which this Type object was loaded.

I would say you need to evaluate what you want to do and come to an understanding of how long it's going to take :) For this goal I would recommend:

  • fundamentals in illustration, lighting, both traditional and digital (take some courses)
  • learn the math involved in pixel art!
  • follow lots of tutorials on creating art in general
  • learn Unity fundamentals (through the tutorials I linked earlier)

basically I would say in order to actually take on the project of making a game, you pretty much need the knowledge and experience to do it intuitively.

If you want a more simple, easy route check out rpg-maker. Also might wanna move this discussion to a more general channel.

What is the best way to learn how to code? I know people are probably going to say documentation, but so what, do people just look up loads of documentation, and then string up their code with documented code hoping it'll work?

#

like combining code documentation?

spring nacelle
#

The best way to learn how to code is to start with something you want to do or make, then research the skills you need as you need them

inner shuttle
#

bump

spring nacelle
#

There are myriad tutorials for anything you may want to do

pure ore
#

I don't want to really do tutorials, I want to come up with my own code, plus tutorials don't teach you much beyond doing it how they do

spring nacelle
#

unless you're willing to take classes and learn directly from someone else helping you, tutorials are the only other real way of doing it

leaden ice
spring nacelle
#

you aren't going to learn code by brute force or by putting your head into the documentation

#

You start with tutorials, then modify them to suit your needs

leaden ice
#

Documentation is reference material, not learning material

pure ore
#

oh no? I thought it was as simple as taking Mathf.Deg2Rad in the documentation, looking up what is does, and adding that into your code

leaden ice
spring nacelle
#

even me, who's been doing this for years, still uses tutorials for things I don't know. Though I spend much less time iwth them

leaden ice
#

You can and should do this

#

But that won't teach you those principles, like what a function is and how to call it

untold basin
pure ore
#

But I don't understand, tutorials are limited, let's say you find a tutorial for a basic character controller, but your game needs something more, how do you figure out how to expand it programming wise?

untold basin
#

if you want to do everything from scratch with no help AND you don't know how to code, GL I guess ? There's a huge resource for !learn ing how to use unity

figure out why the character controller you got from the tutorial does or doesn't work, then change it

leaden ice
#

But looking at examples is a starting point and yes you would combine this with reference material to come up with a solution

pure ore
#

So basically just throw anything at the wall until it works?

Sorry guys, I have a learning disability so its hard for me to understand

subtle cradle
#

Anybody out there using VSCode (with Gemini)? any tips for prompt engineering?

leaden ice
#

A learning disability certainly adds challenge

#

Tutorials etc build up your base knowledge of what's possible and how

#

And may provide inspiration or a starting point for code and scene setup

pure ore
#

So let's say I wanted to add physics. I know that Vector3.up means down, so I would do m_SomeVector = Vector3.MoveTowards(m_SomeVector, Vector3.up, m_Gravity * Time.deltaTime);

spring nacelle
#

when you say... 'add physics' what do you mean? do you just want things to respond to gravity?

pure ore
#

Yes

#

I.E my player

Does your object have a rigidbody on it?

pure ore
#

I use character controllers

leaden ice

pure ore
#

Oh so I would do -Vector3.up

leaden ice

Vector3.down

spring nacelle

#

Or yes that

pure ore
#

Because I had it go up not down

leaden ice
leaden ice
pure ore

I think you need to slow down a little and think about what your code means. You might be rushing and not understanding.

pure ore
#

Yeah. here's the thing

#

So there's this game called Bendy and the Ink Machine, I talked to the programmer on that, and he even held a press conference at a location I forgot, but he said he learned to code by googling "how to do this in unity" the only thing I don't know was how he expanded it for the sequel

naive swallow
#

The next step is to actually do that thing in Unity, see what went wrong, and remember that for future use

pure ore
#

@leaden ice Vector3.up has to mean down because when I negate it, the player goes up

simple egret
#

Depending on what you're using, the player itself might be upside down

#

Make sure its local Y axis (green) points up

#

Some methods will convert your vector to local space before applying it, like transform.Translate

nvm it was an issue with another float value I was using

those who used addressables, did you ever face untracked memory growth while using scene load and unload? i am trying to figure out what could be the reason, can't see any light at all. i am thinking is it any device specific problem? i don't have any other other device except my pc right now, not even a mobile. can anyone help me to get my sample test project shared to see if you too are getting the untracked memory? this could give me relief whatever the result comes. sorry to bring such topic here

i will share the file link soon

cosmic rain
#

My guess it's just part of unity implementation and there's nothing you can do about it.

warm badger
#

yeah that might be true, but look at my screenshot from memory profiler window, first one is before scene load, second one after scene load, last one after unload. even after unloading memory only goes down 3mb, then where is the benefit of using addressables to unload things to free up memory. I think i am wrong with my project somewhere, I am really grateful that you agreed to help me. please look into it a bit.

# warm badger yeah

Did you try loading/unloading multiple times? Does it keep on increasing by ~50mb every time?

#

If not, it could just be unity reserving the memory and reusing it afterwards.

warm badger

sometimes more again sometimes less

cosmic rain
#

Well, I'll have a look when I get back, but don't get your hopes up. I can only use the same tools that you do, so it's unlikely I'll figure out something new.

Might be a good idea to post on the forums. Perhaps some unity staff would see it.

Hello, i have a script holding a reference to a generated input actions class from the input actions asset.
When i adjust a script during playmode the instance or reference to it seems to be gone.

_inputActions = new InputActions();

Is the code i have for creating an instance.
Could it be this instance is deleted when Unity reloads a script during playmode after adjusting it?
Are there methods that do get called when it's being reloaded to make sure it works flawlesly in the editor too?

That depends. If you want to do 3d in the future, you can start with 3d (or 2d to get the basics then move to 3d), it's all about what would be more comfortable for you. But if you like 100% sure that you want to do for example only mobile 2d apps, you don't need to know 3d at all

If you want different materials there are absolutely no way to avoid multiple draws

cobalt bloom
#

How do I generate submeshes

leaden ice
cobalt bloom
#

I'm drawing the mesh using the Graphics.DrawMesh. Do I have to use a MeshRenderer for this, or can I just generate separate meshes instead of using the submesh stuff.

finite ferry
#

I have a script that from time to time stops working, or I guess "updating". It stops working when I make changes in other scripts but starts working again when I make changes in it. I have no idea why it acts like this and it drives me crazy since I've already spent hours trying to fix the problems that this causes. But it wasn't until recently that I understood that this script was the root of the problems.

FYI: The script is a public class that doesn't derive from MonoBehaviour and I do not get any errors from it, whether working or not.

#

(With "make changes" I mean typing something, anything, and saving).

#

This is the script:

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

[Serializable] public class Cooldown
{
    [SerializeField] private float _cooldownTime;
    private float _nextFireTime;





    public bool IsCoolingDown()
    {
        return Time.time < _nextFireTime;
    }

    public void StartCooldown()
    {
        _nextFireTime = Time.time + _cooldownTime;
    }
}```
leaden ice
#

that's the point of it - to render meshes without a MeshRenderer

#

Also RenderMesh is the newer API

cobalt bloom
#

nono I know

cobalt bloom
#

RenderMesh doesn't exist

#

anyway, I meant that does Graphics.DrawMesh support multiple materials? If so, how do I give them to it

leaden ice
#

It would be one DrawMesh call per Material/SubMesh

cobalt bloom

I've tried the firebase help discord, but it is so incredibly inactive and unhelpful:
Using firebase with Unity, my client crashes when I try to login.
The conditions that cause this are when someone is already successfully logged in and then someone else tries to login. This 2nd person's client crashes

        public async Task<bool> Login(string _email, string _password)
        {
            try
            {
                Debug.Log("Bruh 1");
                // Call the Firebase auth signin function passing the email and password
                var loginTask = auth.SignInWithEmailAndPasswordAsync(_email, _password);
                Debug.Log("Bruh 2");
                // Await until the task completes

                Debug.Log("Bruh 3");

                User = loginTask.Result.User;

                DocumentReference docRef = DBreference.Collection("users").Document(User.UserId);
                Debug.Log("Bruh 5");

My crash logs never make it to the Bruh 5 debug log, but successfully shows the correct User.UserId. Any ideas?

there is no guarantee here that the log has even printed yet, the only guarantee is that it has been enqueued to your dispatcher queue

# somber nacelle but *even still*, awaiting MainThreadAsync does not guarantee that your log has ...

From what I experienced, it is exactly doing that, guarantee that I get the correct order
The first one logs in the wrong order. It fires test me before the enqueued log. In this case, its expected, but I have nested tasks where the logs got messed up and I wanted to have a clean understandable logging of what is going on.

 await Debug.LogQueue("AR Supported: " + arSupported + ". Fallback to non tracked runtime.", this);
Debug.Log("Test me");

This one logs correctly one after the other

await Debug.LogQueue("AR Supported: " + arSupported + ". Fallback to non tracked runtime.", this);
await Debug.LogQueue("Test me");
#

This especially was an issue, when I needed to access unityengine parts in background, so I had to enqueue and wait for the mainthread , then continue

somber nacelle
#

that's not really related to you awaiting that method though, that's because of the fact that you are queueing your logs with a queue then presumable dequeueing them in that same order on the main thread

plucky inlet
#

And also, the object, as you mentioned, was causing issues, so both issues made me do the enqueued log.

Would using a TCS solve this? Maybe the timing issue at least

Task LogAsync(string message)
{
    TaskCompletionSource tcs = new();
    Dispatcher.Enqueue(() =>
    {
        // ...
        tcs.SetResult();
    }
    return tcs.Task;

Completing the task in the Enqueue method will stop the caller from awaiting. At this point your log should be printed and the execution will resume past the await

plucky inlet

So the Awaitable.MainThreadAsync() is not actually awaiting for mainthread and then continue?

Hi guys

#

How do I get and output this data to Unity from Telegram?

image.png
plucky inlet
# somber nacelle but why would you *want* the caller to be paused for that? if the only point was...

I just removed the dispatcher enqueue entirely and just used the awaitable mainthread method to log after that. Still need to wait for the log, because I want, as said already, my logs to be in correct order. Task doing something in background, starting another task that checks on whatever, doing some log too. If I let them all just log together on the mainthread, it would just be a random order of logs at whenever the mainthread is cycling. Thats why I was waiting for the mainthread in the log. And as expected its working as before, but makes more sense now as you guys stated to not await and then do nothing. Thanks for your input and suggestions!

plucky inlet
somber nacelle
#

well now you're just potentially slowing your code down even more when you continuously hop from background threads to the main thread. and even then, why not just do the work on the main thread in the first place if you don't care about needing to do so? the dispatcher already controlled the order of the logs as i've described to you countless times at this point. you just refuse to understand that for some reason, all you needed to do was make that LogQueue method return void and no longer be async and it would have worked just as well as it already was, but without the pointless awaiting

plucky inlet
somber nacelle
#

i'm not saying you can't use async for other things. i was simply pointing out that LogQueue has really no reason at all to be async if you were just enqueueing the logs to be printed on the main thread

# plucky inlet I still think, its your loginTask, causing issues

Why do you think that? I've made some workarounds to be able to proceed around my DocumentReference docRef = DBreference.Collection("users").Document(User.UserId); line, which is my suspected crash point.

But now it proceeds to two other spots that call something very similar and crashes there. Commenting those out allows me to proceed without crashes

And again, this works if only one account logs in. It is once the 2nd one logs in while the first is still logged in that it crashes

what's the best way to make an object follow another object's movement but with a multiplier?

#

so if object A moves 10 units, object B would make the same movement at half speed and move 5 units

vagrant blade
#

Multiply the speed of the object by a scalar value, such as 0.5 for half the speed.

#

For following, entirely depends on how you're moving things. You want a straight line? Just move it towards it via MoveTowards(...)

dim umbra
#

yeah, probably should have mentioned that it doesn't use velocity

#

trying to make a parallax background

#

here's the (relevant) camera movement code

            if(Vector2.Distance(targetPos, transform.position) < 1f && Vector2.Distance(targetPos, transform.position) > 0.01f){
                speed = 1/Vector2.Distance(targetPos, transform.position);
            } else {
                speed = 1;
            }
            
            if(Vector2.Distance(targetPos, transform.position) < 0.01f){
                transform.position = targetPos;
            }
#

don't remember the way to make that c sharp formatted

vagrant blade
#

Multiply your final speed by some scalar value

#

But if you want it to be a % of the target speed, it really should just take the speed of the target rather than calculating its own and multiply against that?

dim umbra
#

I don't understand what you're trying to say

#

I want the object to move at a fraction of the camera's movement

vagrant blade
#

You want ObjectB to move the "same movement" as ObjectA but half the speed. So get the speed of ObjectA and multiply it by half.

dim umbra
#

i thought there would be some shortcut for this but i guess if that's the only way, i'll do it

#

it's just annoying because of the code that adjusts the camera not based on speed

#

so i'll have to recreate that for the other object

leaden ice
dim umbra
#

oh, yeah that probably works

#

I'll try

#

yep, works perfectly

Hi! I'm trying to make sort of a modular system, with a class for each different module. I have an issue though, that if a class inherits from another class, I don't seem to be able to have that class have some variables different from the parent class? Example:

public class ModifierTemplate : MonoBehaviour
{
    public int multMultiplier = 0;
    public int numMultiplier = 0;
    public int flatMult = 0;
    public int flatNum = 0;
    public bool addNumberToNum = false;
    public bool addNumberToMult = false;

    public void triggerModifier(GameWheel wheel, NumberTemplate number)
    {
        wheel.mult += flatMult;
        wheel.num += flatNum;

        wheel.mult += (wheel.mult * multMultiplier);
        wheel.num += (wheel.num * numMultiplier);

        if (addNumberToNum){wheel.num += number.number;}
        if (addNumberToMult){wheel.mult += number.number;}
    }
}

public class x2Mult : ModifierTemplate
{
    
}

In this example, I wan't the x2Mult class to inherit the modifiertemplates triggerModifier function, and it's variables, but I would want for the "multMultiplier" variable of the x2Mult class to be different from the modifiertemplates class.

How do I do that?

hexed pecan
knotty sun
wispy depot
knotty sun
#

otherwise

public class x2Mult : ModifierTemplate
{
    public override int multMultiplier = 1;
}
wispy depot
#

Oh, I need to use the override! Thanks! Massively helpful, I didn't even know override existed.

knotty sun
#

and

public class ModifierTemplate : MonoBehaviour
{
    public virtual int multMultiplier = 0;
wispy depot
#

Thanks!

wispy depot
knotty sun
#

oh, try this

public class ModifierTemplate : MonoBehaviour
{
    public int multMultiplier = 0;
...
public class x2Mult : ModifierTemplate
{
    public new int multMultiplier = 1;
}
wispy depot
#

I think that works, yes. Though rider is telling me the x2Mult's "multMutliplier" variable isn't being used, is it supposed to be like that? Is that a quirk of Rider or does it mean that it won't work?

knotty sun
#

that's rider gatekeeping

wispy depot
#

Thanks!

knotty sun
wispy depot
knotty sun
#

oh dear, sounds like you need some basic C# learning.
abstract means that the class itself cannot be instanced but classes that derive from it can. It's a kind of protection ideal for 'Template' classes

wispy depot
knotty sun
#

then you should be able to make the variables virtual and the method virtual as well

wispy depot
#

As for the learning bit, that's why I'm on this discord, isn't it? I will admit though, my knowledge of C# is quite holey, as most of my learning has been from figuring it out myself and using stackoverflow

wispy depot
knotty sun
wispy depot
wispy depot
knotty sun
lean sail
#

Virtual would be for methods or properties.

lean sail
wispy depot
#

There will be other classes inheriting from the modifierTemplate class that will need a different formula/method though

knotty sun
lean sail
wispy depot
lean sail
wispy depot
lean sail
#

And again because these are monobehaviours you dont need another script for this. You assign the value in inspector. The only thing this changes is the default value when you create the script

wispy depot
lean sail
#

Is there a reason you're using monobehaviours then?

knotty sun
wispy depot
lean sail
#

I assumed you were planning on using AddComponent at runtime, which isnt common at least from what I've done

knotty sun
#

you can only instance a MonoBehaviour using AddComponent

wispy depot
#

Thinking about it, I suppose I don't need them to be monobehaviours - that was just me not thinking about it

lean sail
#

Yea this could probably just be it's own plain c# class and youd save a bit of performance if theres a ton of modifiers

knotty sun
#

and, it will follow the rules of C# not the rules of Unity

wispy depot
#

Yeah I did that now

lean sail
#

Though I still do find it unnecessary to create a whole new class just for a default value to change. When you create an instance of that base class, all those values are 0. Surely you plan to assign some values to those modifiers. Maybe itd be better if you just change the formula in the x2 multiplier class instead

wispy depot
lean sail
# wispy depot It is necessary because of how other aspects of the game is structured. I could ...

That last point was less about performance. It's more about how you're going to be assigning a value to this class somehow when its new()'d. Maybe in the constructor, maybe just by changing the public variables. If you dont do this then well all the values are 0 using the base class.
Now if you want to use the x2 multiplier class, this would imply you're now using the default values. If you assign the values like you will be doing using the base class, then theres no point in having a different default value.

#

And if you're creating an instance of this derived class, you already know it's supposed to be a 2x multiplier so you could just assign it larger values. Or use the constructor, pass it in a value, and it automatically multiplies it by 2

# plucky lance Anyone got a good tutorial for a rts style system

Way too broad a question, what part of RTS style system?
Some general overview, I liked: https://medium.com/codex/making-a-rts-game-1-placing-buildings-unity-c-c53c7180b630
Rather long and textual tutorial though, and not at all best practices, just basics.
Just creating good pathfinding, like in SC2 is a full time job in and off itself.
If you want to make Supreme Commander/BAR type game, you need to do things very different.
So we don't really have a way to give you a 'good tutorial'.

when i run webgl build and start server using netcode for game objects, it gives error:
Exception: WebGL as a server is not supported by Unity Transport, outside the Editor.

somber nacelle
#

#archived-networking
But also, that is accurate. you cannot use the unity transport on webgl unless you use the netcode for gameobject 1.2.0 version (or higher) with the unity transport version 2.0.0 (or higher). so presumably you are using an older version of one of those packages

#

oh and don't crosspost. you originally posted in networking whihc was the correct place to do so

whole night
#

i can only see 1.1 in package manager for netcode for gameobjects

somber nacelle

what version of unity are you using?

#

2022.3.49f1

somber nacelle
#

show what you see in the package manager then

whole night
somber nacelle
#

that's 1.11 not 1.1

#

and last time i checked 11 > 2. so the issue is likely the transport version

Oh, i thought 1.2 > 1.11, my bad

somber nacelle

no these aren't decimal numbers, they are semantic versioning numbers.

isn't the latest version of the transport 2.2.1? 🤔

Quick question for the AI folks:
Are there AIs that I can integrate into my Unity project to look at the code and answer me questions like "which script does such thing?", etc?
I basically want to avoid the problem of returning to old projects and not remembering what things do what
at the moment, only looking at scripts would be enough for now. Extras are welcome thought 😛
I'm also willing to write descriptions in my scripts (as commented code) explaining what it does if it's useful for the AI

Im currently adding a moba like progression to a prototype im making, with items that increase your stats and add special effects to your attacks or abilities, im thinking ill implement this by keeping an inactive prefab of each attack and ability on the player as a child, and duplicate them when i need to actually spawn them, and whenever an item is bought that adds an effect, i add a script that applies said effect to the inactive prefabs at runtime

how viable is this solution?

My game has some calls to Camera.ScreenPointToRay(Input.mousePosition) that is spamming up the console when I start with "Screen position out of view frustum (screen pos inf, inf) (Camera rect 0 0 2560 1440)" messages until I click on the game window. It's not an exception, it's just an error log message, but it's a little annoying. How do I get the "view frustrum" from the camera..? Or do I just need to check for Input.mousePosition.x or .x == infinity? I couldn't find what I need in the API docs for Input and Camera

#

(do I just compare mouse position to Vector3.positiveInfinity?)

rigid island
modern creek
#

(I just added the lines at the top with all those guard clauses)

#

The line in question is the Ray ray = Camera.main ... line

#

Input.mousePosition reports as positiveInfinity until I move it somewhere in the game window.. after that it's fine

rigid island
#

did you change anything on the camera?

modern creek
#

Whatcha mean? I changed lots of things 🙂 but I'm using cinemachine for some custom zooming/tilting

rigid island
#

can i see the main camera component RQ when this error happenes

#

sure, lemme comment out those guard clauses.. sec

somber nacelle

this is likely just a quirk of unity not capturing the mouse for the game view until the game view is manually focused

modern creek

oh okay position all looks good, so yeah prob what box said but I have no clue it doesn't happen to me

somber nacelle
modern creek

it only happens if I start the game in Scene view, btw

#

I could do that too.. although I'm not sure if that's gonna have weird effects if the user has their mouse in the middle of the screen then alt tabs out.. like.. I'm doing a lot of the input handling manually for map drag/tilt

#

map drag/scroll wheel = pan & tilt

somber nacelle
#

wrap it in conditional compile so it's only included in the editor

modern creek
#

well, it might happen in the web too.. in fact it might almost be guaranteed to happen in the web? I'm not sure if the applet is gonna have focus by default

#

I'll check into it.. I might need to have the user click on the applet to start anyway so I am guaranteed to capture input

sup gang

#

would it be better to have a for loop for this?

# 
//Set Verified Decks List
_allDecks = decksToLoad;
_totalPages = Mathf.RoundToInt(_allDecks.Count / 5) + 1;

Debug.Log("Total Decks: " + _allDecks.Count);
Debug.Log("Total Pages: " + _totalPages);

//Instantiate all decks buttons
foreach (DeckSO deck in _allDecks)
{
    //Set page transform,
    //5 decks per page
    Transform pageTransform = transform;

    int currentDeckIndex = 0;
    var butt = Instantiate(_deckButtonPrefab, pageTransform);
    butt.GetComponent<Button>().onClick.AddListener(() => SelectDeck(currentDeckIndex));
    butt.GetComponent<Tooltip>().SetToolTipMessage(deck.Description);
}```
#

I have a list of decks, which it will create a page for every 5 decks

rigid island
#

as oppose to what?

solemn ember
#

for each page, it will instantiate a button (up to 5) for each deck

rigid island
#

the only thing I would change mainly is the AddListener and also make it its own class that has already those as props

solemn ember
#

I'm instantiating this

#

a for loop, to count on the deck index

rigid island
#

I can see that. But you can skipp add Components if you already had those assigned as props

#

and AddListener, I rather use an actual method assigned to it so I can clean it up

solemn ember
#

my add listener is fine

#

I want to focus on the ID

#

every time I instantiate a deckButton in the list, I want to assing an ID to it

rigid island
#

so whats stopping you?

solemn ember
rigid island
#

you have to increase the index you can't define it in the loop or you keep overwriting it with 0

solemn ember
#

I'm trying to figure out how to get the index

#

oh

#

so I need to make an int, outside of the loop

rigid island
#

if you plan on increasing it each iteration, sure

solemn ember
#

yes

rigid island
#

also why not just use a for loop in that case

solemn ember
#

okay let me see what I can do

solemn ember
#

that's what I was asking

#

xD

#

if it was better

rigid island
#

I wasn't sure why you asked if a for loop was better sorry

they're instantiated properly and I can select them

cause the index in the tooltip message is assigned correctly

short quiver
#

I have an implementation question that I'd like some guidance with: I have Characters with a set of abilities, where each character is a prefab, and the character's abilities are also represented as a list of prefabs within the character prefab. My problem is as follows: In the general case, each cast has an individual cooldown, but I'd like for my implementation to handle the case that different casts share a cooldown. Some relevant code snippets:

public struct CastContainer {
  public Cast castPrefab;
  public int cooldown;
  public int timer;
  // ...
}

public class Character {
  public CastContainer[] castContainers;
  // pseudocode regarding cast:
  void FixedUpdate() {
    if (canAndWantToCast(castContainers[i])) {
      Cast(castContainers[i].prefab);
      castContainers[i].timer = castContainers[i].cooldown;
    }
    // ...
  }
}

So, in the general case, each cast handles their own cooldown. However, I want to flexibly handle the case that, in some fashion, I've told my game that if cast0 OR cast1 are casted, I want both to go on cooldown. How might I elegantly write this? I can think of ways off the top of my head, but nothing that doesn't feel hacky 😦

soft shard
# short quiver I have an implementation question that I'd like some guidance with: I have Chara...

One way that comes to mind is firing an event or calling a function that will happen on all casts, that event/func could take a "CooldownType", enum or ID, and if cast0 and cast1 have the same ID or "type" when that event is fired, they can respond with starting their own cooldown - for something like cast2 to not respond in the same way, it would only need a different ID/type than cast0 and cast1 would be using

Using context steering, how can I make an enemy reach its target behind a wall? Whenever I try it just gets stuck facing at the wall.

Basically I have it set so that the enemy uses a dot vector between the target and each direction and then gives said direction a positive weight. Then it raycasts to each direction to check for obstacles, then if so gives it a negative weight. The substraction from the positive and negative result in the direction to move. Whenever the target is behind a wall the weights on the direction to the target just cancel each other out and the others just stay at 0

Hi, guys! I am working on animation for my player and have a question. I am using WASD input to set the proper direction animation. However i think it is better to check the direction movement of the player and set animation in accordance with it. How can i determine player direction using this input?

movementX = Input.GetAxis("Horizontal");
movementZ = Input.GetAxis("Vertical");

knotty sun
#

ah, missing the word reference

celest vault
#

well, i guess how can i include the dll as a reference without it being overwritten

knotty sun
#

put it in a folder called Plugins in your project

somber nacelle
#

if you are not using assembly definitions in your unity project then simply including the dll in the project is enough

celest vault
#

as a .net dev this is a nightmare lmao

somber nacelle
#

yes well hopefully with the switch to the coreclr in the next couple years it will be a more normal process

knotty sun
# celest vault as a .net dev this is a nightmare lmao

personally what I do, is have my source files in folders external to Unity. I create symbolic links into the Unity projects and I use links to them in my .Net solution projects to get them into my solutions for creating dll's, that way I have one code base I can work on both inside and outside Unity

celest vault
#

related-ish, how could i create a modding api (like an IMod interface) that the game can then load? my idea was to let users compile their own project using the modding api as a nuget package and place the resulting dll imply in MyGame_Data/Managed, which i'm hoping is then loaded by mono. i'm just not sure what to do from there.

oh yeah btw im new so can i get help on like how to fix bugs and ask for ideas?

rigid island
loud igloo
#

ok and 2 more questions; what should i start with 2d or 3d, and what can i use for pixel art(for free,im poor)

rigid island
#

both apply the same exact concepts, doesn't change much in those terms. Also there are plenty of free assets, nothing stops you from getting those to start with

#

check places like asset store and kenny

loud igloo
#

yeah but im trying to but a little bit more effort because i know how to acctually draw

rigid island
#

so don't you have an app to draw already?

#

just export it to unity

#

they have plenty of software out there for pixel art

loud igloo
rigid island
#

something like asprite

#

for pixel art

loud igloo
#

0k and the frames for pixel art are just pictures right?

#

like animations

rigid island
#

a series of frames like any moving picture yes

#

Unity has its own Animation tool you just put the frames

loud igloo
#

oh ok so any other things i need to know?

rigid island
#

would suggest you go through the !learn pathways, start with the Essentials it shows you a lot of the tools esp 2D

tawny elkBOT

Over 750 hours of free live and on-demand learning content for all levels of experience!

I've recently incorporated object pooling into my game to improve performance, so it's new to me. I need to change the sprite of one of the objects that's currently in the pool while the game is running. If there's a hundred gameobjects, I don't know if it would make sense for me to do a loop to change the sprite of all those game objects (could cause a lag spike?), or if I'm better off just making an entirely new pool with game objects that use the different sprite. Does anyone have suggestions on a best practice for this scenario?

steady moat
waxen blade
# steady moat Just change it when you unqueue one.

I guess I would have to store the new sprite somewhere, and everytime an enqueue occurrs, do an if statement to see if the current sprite matches the new sprite, if it doesn't, change it to the new one?

#

I have this code to create a lobby, which is an "Async" void

#

so I can use await, try and catch

#

what if, from another script, I call this function

simple egret
#

It'll execute, but you cannot await it from the calling mehod

#

(since it does not return an awaitable type, like Task or Task<T>)

solemn ember
#

😦

#

I'm using the "RoomFound" bool for this, but it's prone to errors

#

see here

image.png
simple egret
#

Exceptions will not be bubbled up either (since it's when you await that the runtime checks if the an exception occurred), but you're covered on that since the whole contents of the method is guarded with a try/catch

solemn ember
#

it waits 2.5 seconds and checks for the bool "RoomFound"

#

hmm I see, I guess...

chilly surge
#

If you want the caller to be able to await your CreateRoom, and you want it to tell the caller if the creation was successful, then make it async Task<bool> and return the result.

solemn ember
#

I should make a function here, and call it from my actual CreateRoom()

solemn ember
#

so make this a task

#

that returns a bool

#

and here

image.png
#

I could have the await and it will work?

simple egret
#

That method isn't async so you cannot await in there

solemn ember
#

yup, I would have to also make it a task

#

I think

chilly surge
#

Eh, I would not recommend using both async/await and coroutines together. They both (more or less) do the same thing, stick to one or the other.

#

Ideally you'd just use async/await for everything, or coroutines for everything, not both. If you have some foreign code that uses a different mechanism, wrap it into a task/coroutine.

solemn ember
#

LobbyRoomManager.cs

image.png
#

MainMenuUIManager.cs

image.png
solemn ember
#

but yeah... they're 2 different scripts

simple egret
#

I guess you could do a custom coroutine type that starts an async task and periodically checks whether it's finished, but it's indeed better to stick to one of the two systems exclusively

solemn ember
#

👀

#

could I get a ... napkin code as an example of what I should do?

chilly surge
#

Make a decision first, do you want to use tasks or coroutines?

solemn ember
#

I have never used tasks

#

so I don't know

#

whatever you recommend I'll try it

#

I normally use coroutines, a lot

chilly surge
#

Async/await is task.

#

If you decide to stick to coroutines, then turn all your existing code into coroutines, no async/await. If you have foreign code that uses async/await, wrap them into your own coroutines.

solemn ember
#

well I rather keep my Task

solemn ember
chilly surge
#

Then I would recommend use task for everything, including rewriting your existing coroutine code into tasks. Mixing the two will just lead to problems later down the line.

#

Well, it has already led to problems, as the one you are having right now.

solemn ember
#

so I should turn my coroutine into a task

#

I'm down for that

chilly surge
#

If you are going that route, I can recommend UniTask.

solemn ember
#

👀

chilly surge
#

You can work on rewriting you existing coroutine code into async/await, and you won't have the problem of mixing the two anymore.

solemn ember
#

that... sigh

#

what do you think of this solution

#

MainMenuUI.cs these will call the tasks from my other script

image.png
#

to create or join the task

#

and in my other script, I'm calling the Coroutine

image.png
#

which will execute UI stuff there

#

what do you think of that?

chilly surge
#

This is quite a mess, the coroutine in your first script calls an async method in the second script, and then when that method finishes it now has to start a coroutine of the first script

solemn ember
#

no

#

only one coroutine

#

they're void now

#

Void > Task > Coroutine

chilly surge
#

Okay sure, but from my understanding, your first script is where the actual logic lies, your second script is only there to handle the create/join part, and then it should hand the control back to first script.
But because you don't know how to do that, so instead the second script calls some method in the first script after it's done, effectively spliting your main logic into two scripts.

solemn ember
#

👀

#

yes

chilly surge
#

Which is my point about not mixing coroutines and tasks, if you use only one of them, the main logic will sit only in the main script, and the part that calls the second script will just await/yield it and continue. The second script will no longer need to even know the first script exists, untangling this mess.

solemn ember
#

🥴

#

but I wouldn't know how to do that

#

"Use UniTask"

chilly surge
#

I gave you the decision to "use only coroutines" or "use only tasks" but you still haven't decided yet.

#

Or I guess there's a third option, still using a mix of both.

solemn ember
#

I want to use a task to create the room

#

I assume it's what's best

chilly surge
#

It doesn't really matter which one you choose, but choosing one means you want to write everything in that, and not mixing them.

#

Unless you don't have the time to rewrite existing already mixed code, in that case you can wrap task into a coroutine (or wrap coroutine into a task, depending on the caller)

solemn ember
#

I don't know if I want to use UniTask

#

but I'm down to make my coroutine, a task

#

that way I have both tasks

chilly surge
#

Make your decision:

  • I want to use tasks for everything, and I'll rewrite all my existing coroutines into tasks (you will want to use UniTask for this so your life is easier)
  • I want to use coroutines for everything, and I'll rewrite all my tasks into coroutines.
  • I don't have the time to rewrite and just have to mix the two.
solemn ember
#

btw the coroutine

#

it's just to have some delay on my UI, it looks smoother that way

#

btw

#

I have to download UniTask from github?

#

or I can add it through the package manager

chilly surge
#

Have you decided 1 2 or 3 yet?

solemn ember
#

all tasks

chilly surge
#

Yeah you can add UniTask via package manager, their repo README has instructions.

solemn ember
#

one sec

#

I'll brb in like 5-10

#

what I did work nicely, but I'm willing to improve my code

#

if this is better

#

I'll brb in like 10 minutes tho 😦

Can someone refresh my memory on Gameobject cloning and spawning? I was going to offload some of my code that handles creation of objects into a separate script but remembered you can only instantiate in monobehaviors

#

All it does is basically copy a gameobject, strip everything except for mesh renderers and filters and apply a specific material to them. Ideally it's just a helper method that takes in any gameobject and returns processed one

#

Would this be possible without adding a whole another component to a gameobject?

Instantiate is a static method. You can call UnityEngine.Object.Instantiate anywhere

I'm just getting my applet stood up (webgl app) and there's a lot of visual tearing and failed antialiasing in the applet (but not in editor or in windows builds). What.. do I need to explore to configure and fix this?

(look at the edges of the hexes - left image is the webgl applet)

crude mortar
#

both look equally aliased to me

#

left image:

image.png
#

right image:

image.png
#

one is just much lower resolution

#

its not really an aliasing problem, more like just seeing a completely different color through the cracks in the ground

#

which will naturally create those small pixel gaps due to monitors being pixel-based and objects in the world being floating-point-based

#

(can't speak to the tearing though, sounds like vsync issues with the engine on that platform and no clue if you can do anything about it)

modern creek
#

sorry, I didn't mean tearing like vsync tearing, I meant the antialiasing

#

it's really bad on the web version.. but it might be a resolution thing .. I just noticed i'm running the editor build in 4k and the web build in 1920x1080 from the canvas size

#

I'm not really sure what the appropriate method is - like.. size the canvas with javascript to the browser size?

Update, LateUpdate, a coroutine that has a loop that runs every frame, or something called from one of those places.

That's more of what I was looking for, I'd imagine the overhead however small it might be would be better, but then again maybe the new event system is using the same update code something similar to detect.

How do I change the "Color Over Lifetime" property of a Particle System at runtime? This doesnt seem to change anything, ive also tried changing col.color.gradient directly without the g variable and looping colorKeys to change it, am I missing something?

for (int i = 0; i < vfx.Length; i++)
{
var col = vfx[i].colorOverLifetime;
var g = col.color.gradient; g.colorKeys[0].color = g.colorKeys[1].color = tone; 
col.color = g;
}
leaden ice
soft shard
# leaden ice `vfx[i].colorOverLifetime = col;`

Thats the strange thing with the particle system, you cant assign those properties directly, for example

var main = vfx[i].main; main.startColor = tone;

is all thats needed to set the start color, but doesnt seem to be the same for color over lifetime, if I try vfx[i].main.startColor = anything I get a read-only error, same with vfx[i].colorOverLifetime = anything, same for any of the sub properties like vfx[i].colorOverLifetime.color = ...

#

Now im really confused, creating a new GradientColorKey[] and passing that seems to work, but why would I absolutely have to create a new struct for this? Why cant I just change one value of the existing struct? Doing it this way means if I have 5 color keys, id have to make a new array, loop through all 5 just to change 1 then pass that whole new array, instead of just change the 1 index directly, is this the only way?

detect if your player is trying to climb steps. do the raycast. teleport him to the new position if it succeeds.

#

theres probably some other checks you'll need to do, but that's basically the gist of it

#

you should probably draw lines as well to make sure your raycasts are happening in the right spot

I ended up getting the script to work

why do i get this error:

IndexOutOfRangeException: Index was outside the bounds of the array.
UnityEditor.Editor.get_target () (at <c84e7af800564ed28d201f1f7edf8e24>:0)

that is this line of :

private void OnEnable()
{
    _asset = target as WallManager;
}```

i don't see why that would be an error ive made plenty editor scripts in my time and i've never had this issue before.
#

im going to assume it must be an engine bug not something i've done since i dont have access to get_target

Are you doing some weird multi target selection event from the inspector?

#

class variable WallManager _asset;

dusk apex
#

Reducing the complexity by removing the assignment and cast from the equation.

broken light
#

no they both print WallManager

#

the editor seems to work even with the error popping up

dusk apex
# broken light no they both print WallManager

So if you do not execute that statement and simply log the two there are no errors? (not caring if it works or not, simply if there is an error being thrown or not) cs private void OnEnable() { Debug.Log($"asset: {_asset}"); Debug.Log($"target : {target}"); Debug.Log($"target as WallManager : {target as WallManager}"); //_asset = target as WallManager; }

it seems to all show wall manager correctly even for _asset when it should technically be null v.odd

# solid relic Yeah that won't work because it can be any rotation

it'd work, you'd just need to rotate the object according to the raycast hit's normal (probably using Transform.LookAt but it depends on your object)
you'll have to do that with either method, more or less - since with dalphat's method you'll need to know which direction to actually offset the object toward, otherwise it'll just go half its size into the surface, probably at the wrong orientation, unless you've already figured that part out

#

(if you want it to be flush with the surface it hits, which I assume you do)

solid relic
summer hazel
#

you shouldn't need to do anything with the collider (unless you're trying to ensure valid placement or something, so that it isn't intersecting with anything). the raycast hit's normal should be be enough, as long as the normals on your mesh aren't a mess i think

#

(at least for the rotation part)

#

if you do try to validate the placement with the collision you'll probably need to offset the placement a tiny bit so they aren't fully touching, or use some method to check how much of the mesh is intersecting with the other one i guess

Hey I'm calling Destroy on an object when I click on it but when that happen i get the following error: (image)

I'm calling Destroy that way:

            if (_health <= 0f)

        {
            CustomerManager.Instance.UnregisterCustomer(gameObject);
            Destroy(gameObject);
        }

Would anyone please know how I can fix that?

#

or is otherwise processing somehow

#

It might help if you do. something like deselect that object before destroying it and/or delay destroying it until the next frame.

fresh hazel
#

Also I tried this EventSystem.current.SetSelectedGameObject(null); but it doesn't do anything

#

My old code was

        protected override void OnDeath()
        {
            CustomerManager.Instance.UnregisterCustomer(gameObject);
            StartCoroutine(Delete());
        }

        private IEnumerator Delete()
        {
            yield return new WaitForEndOfFrame();
            Destroy(gameObject);
        }

#

Yield return null is the way to wait one frame

#

But I might be mistaken about deselecting it being the problem, it might just be because you had moused over it.

Making it block Raycast = false might work better

I am developing an inventory system for an MMORPG and would like to dynamically create objects, even if there are no pre-created ScriptableObjects. I plan to use both random parameters and base parameters for these objects. Additionally, I need the objects to be able to be created on a server request or purchased in a store, with the ability to assign items received from the server. Is this even possible? What efforts and approaches will be required to implement this system? I am considering the possibility of using reflection and flexible OOP approaches.

I have a method that instantiates and fires a bullet every second. In the middle of gameplay, the firerate can be changed by getting upgrades. Its not clear to me how to best get the method to take and use the new fire rate value. Currently I am doing a bit of work around by making a public method of the same name and having it call the private firerate method with ref inputs

boreal jewel
#

the best way would be to make the firerate(of the gun) public, and changing it in the upgrades script when the player gets an upgrade

soft shard
#

Some other approaches that come to mind is using a event in your weapon script, your upgrade menu can fire it if it has a reference to your weapon already, or use a broadcaster/global event if not - or you could make a public property that can be changed and add/subtract it from your fire rate, this way your original firerate can remain private and only affected by the class it exists in, while still accepting modifiers that can also be removed later or possibly saved

boreal jewel
#

I don't think it is necessary to keep the firerate private

soft shard
# boreal jewel nice approach, but if they are unfamiliar with events,they could just make a sep...

This is actually similar to what a public property would do, it acts as a variable but it can also act like a paramless function and do some validation, for example maybe fire rate should never be 10 million

The main reason youd want a variable a class uses like firerate to be private, is cause only that class actually uses the value, everything else might just want to see it, but not modify it directly, when you allow that, then literally any script in your project can modify it at any time, and if thats happening from multiple places, it can be difficult to debug, or run into race conditions where 2 classes are fighting to change the value

Are you supposed to create transforms from position and rotation in order to use point transformations? If I wanna transform a point to local space (location+rotation) but it isn't tied to an existing gameobject, what's the best approach?

somber nacelle
#

if you don't have a transform, then what "local space" is this supposed to be converted to?

blazing tiger
#

I'm blabbering let me rephrase it more coherently

#

I have a point and I need to offset it by some position vector and rotate by some quaternion

#

I could do it separately but I'm pretty sure that's what TransformDirection does anyway. Is there any way to do it in one go?

somber nacelle
#

you can rotate a direction vector by multiplying it by a Quaternion representing the amount of rotation so just do that and add the offset

blazing tiger
#

I'm doing it rn but it was kinda a hassle to provide both location and rotation for 2 objects in a function, was wondering whether there's some transform data type that combines both of these

Hey crew. I'm getting a Unity error NullReferenceException: Object reference not set to an instance of an object UnityEditor.Android.AndroidDeploymentTargetsExtension.StartApplication however the APK is uploaded to my device and I can start it successfully. I tried all the solutions I found online but none of those applied to my situation. Anyone seen this before?

messing around with a little voxel project, and i'm not sure how i can fix my normals. each voxel is part of the one gameobject, created through vertex/triangle manipulation. currently, the individual cubes have the same shading as the whole object should combined. not looking for code, just a list of things to look into, any help would be much appreciated <3

Is there anyway to use C#10+ (a version above C#9) with Unity ?

somber nacelle
#

have you googled it? also you will only get the syntax sugar features from c# 10, you won't be able to use anything that is not supported by unity's .net version

raven storm
#

Does flat namespaces count as sugar?

somber nacelle
#

no

file scoped namespaces

You would also need to manually patch the compiler binary in your Unity editor installation

Not really worth the effort imo.

Can anybody recommend a method of applying and deactivating redundant status effects when effects are applied with a component pattern? For example, suppose I have a state in which a character is made to be drunk for a period of time. What I've seen in the pattern is the following:

public class Drink: Effect {
  private IGetsDrunk Drinker;
  private int timer = 60;

  public void Activate(Target t) {
    if (IGetsDrunk _drinker) {
      Drinker = drinker;
      Drinker.Drunk = true;
    }
  }
  
  public void Deactivate() {
    Drinker.Drunk = false;
  }

  public void FixedUpdate() {timer--;}
}

This solution is pretty nice to me, because the state update is calculated once, and the only calculation to do for the rest of the lifespan is decrease the timer and undo the effect when it's done. This doesn't seem to work if the effect is applied redundantly. For example, if the character drinks a drink at t=0, they can expect to be sober at t=60. If they drink again at t=55, they'd expect to be sober at t=115 (let's say), but the above implementation would make them still sober at t=60. Is there a clean way to account for this in a component pattern?

Hi I'm trying to make an animation script. I made the clip. I'm familier with python but not so much C#. I have 2 characters talking to each other with dialogue (text file containing each line of dialogue). The audio comes through, but I need the characters' jaw to be open while it's their turn to speak, and close when not supposed to be speaking. I wrote this script here, Unity found no errors, but will it do what I actually want it to do?

speaker should match the name of the character object

  1. start is never going to be called, as it's not capitalized how Unity will expect.
  2. I have no idea where you call ProcessScript
  3. Your File.ReadAllLines won't work in a build, and will only work in the editor because the file system is completely different when built (Assets doesn't exist).
  4. Do you have error highlighting in VS Code? While it looks highlighted, I'm suspicious it's unconfigured

I did take part of this from someone else's code

That's in Main.cs whcih controls the whole thing

How would I create an inputmanager for keybinds?
I'm thinking something like this:

public InputManager instance;
public List<keyBind> keyBinds;

private void Awake(){
   if(instance == null)
      instance = this;
   else
      Destroy(gameObject);
}

[System.Serializable]
public struct keyBind
{
    public string name;
    public KeyCode key;
    public KeyCode altKey;
}

And then in my player script it would look like:

if(InputManager.instance.keyBinds[0].key || InputManager.instance.keyBinds[0].altKey){
   // Jump code
}

Why would a dictionary be better?

It would be faster to get the value compared to a list. Though, if you just indexes as in your example, a list would be around as fast. But then you have an issue of poorly readable code, where you hardcode the indices.

So I'm making a rope with IKs, but I'm trying to add gravity. Heres my current idea:

Calculate the ik as normal, then I'll find the middle segment, and move it down. after that, i'll calculate the other to halves back from the center with the anchor thing. I'm trying to figure out how to code it, but I'm wondering if anyone has any other ideas.

I move a pool of objects each fixed update, but since they are marshalled, it ends up with some performance loss. Is there a workaround to keep the transform in memory?

should I just store it as a variable, is it fine?

I guess, just wanted to make sure they don't use a mesh with no way to shade flat which is quite likely here

cosmic rain
#

Even with just 8 vertices

maiden fractal
# cosmic rain Even with just 8 vertices

It is possible with partial derivatives of the position for example but I think they still usually use 24. Some also do that to split the chunks into different directions to cull the ones pointing away from the camera

#

also if greedy meshing is implemented, the vertice count increase isn't that big of a deal

cosmic rain
maiden fractal

Again you can work around that too

And then there is Input.GetAxisRaw("Horizontal"); would i just use

I generate a mesh for my voxel grid, and I make sure to never repeat vertices. However, this makes the lighting off, as the vertices never repeat and so, faces reuse older vertices. This makes the faces render in a similar fashion to balls, which could look nice if the voxels were very small, but it looks off when the camera is close to the voxels.

image.png
#

How can I fix this issue?

cosmic rain
cobalt bloom
cosmic rain
#

Well, the screenshot points out otherwise.

cosmic rain
#

You wouldn't see here whether the triangles share vertices or not.

cobalt bloom
# cosmic rain You wouldn't see here whether the triangles share vertices or not.

They do share vertices because I wrote the mesh generation myself so I know what it does. I basically create a list of each face that would be visible (no voxel is occluding it), and then when I cut the face into vertices and triangles, I check if the vertice is unique or not. If its not unique, I use the index of the vertice that already exists in that position.

cosmic rain
cobalt bloom
#

Is there a way to keep the same optimization while having the normals correct? I know the normals look like the voxels are balls due to the vertice sharing.

cosmic rain
#

Your triangles need not to share vertices to get flat shading.

cosmic rain
#

You can patch this in a custom shader by calculating the normals for each pixel, but that would be even more expensive

cobalt bloom
#

;(

#

I used a similar optimization in a voxel engine I made outside of Unity a while ago and I remember using screen-space normals there too.. I suppose there's no way out of that then?

cosmic rain
#

There isn't. And screen space normals are probably gonna be way more expensive than some extra vertices.

cobalt bloom
#

I guess I'll just keep the vertice unique thing in the trash bin until I find some way to make it useful

#

Thanks!

cosmic rain
#

And to be honest, if you're aiming for a performant engine that can render a huge amount of voxels, unity is probably not a great choice.

cobalt bloom
#

Thanks for the help. Next I plan to implement greedy meshing to reduce vertice count.

stone pewter
#

unity's fine for this kind of thing too, you'll just need to use some of the more low level APIs imo!

stone pewter
cobalt bloom

#

oh, hm, which render pipeline are you on?

#

if it's URP/HDRP then you'll prolly want to use shadergraph

cobalt bloom
#

rn I'm on the default one but if I can use ShaderGraph for this sort of thing then I should probably use it before trying to delve straight into anything too complex

stone pewter
#

I forget if SG has support for the built in RP

#

(I mostly write shaders in the built in RP)

cobalt bloom
#

I believe ShaderGraph should support the built in RP as it doesn't say its for URP but says URP provides support for it

#

but a quick google search says otherwise

image.png
#

so I guess not

stone pewter
#

I think it was added in 2021.2?

#

anyway, you'll want to do something like this:

outputNormal = normalize( cross( ddx(worldPos), ddy(worldPos) ) );
#

assuming the outputNormal is in world space, it might not be

cobalt bloom
#

How do I create a shader in the built in RP? I want to check if it'd be comfortable or not before going with Shader Graph

stone pewter
#

do you want to support lighting?

#

if so then SG is going to make life a lot easier

#

(unity has kind of started discouraging writing shaders by hand through their design ever since shader graph)

#

(writing shaders by hand has a ton of drawbacks if you want to support all the features like lighting, motion vectors, scene view selection, all that. but you get a lot of control!)

#

basically using SG is more future proof lol

cobalt bloom
#

I suppose I don't really need a ton of control for this project anyway, so SG should work.

stone pewter
#

but yeah right click in project view, Create > Shader >, and then Unlit is writing by hand. shader graph should be similar but I forget, I rarely use it henlo

#

might need a package or something

cobalt bloom
#

I used SG before a little so I should be fine

#

hopefully

cobalt bloom
#

Greedy meshing not going very well at the moment ;-;

image.png
#

Can someone more experienced explain to me why my algorithm doesn't work? I basically have a list of every voxel face (that is going to be rendered), and I group the faces if they have the same normal. Afterwards, I iterate over them and check which ones align along the X or Y axes, and merge them if they do.

#

I also check if the distance between them is too much

#

I think I should try to rewrite it fully since this approach is probably wrong

Hi again everyone!

I have a "skill tree" with each skill its script (ItemSkill). The gameobject of the skill contains also the panel that will show when clicked that allow you to upgrade to the next level, and this is for every skill. Since the "price" for the next level will always be the same the initialization of the upgrade panel is made only once at the start.
Wouldnt be better to unlink the upgrade panel from the skills and initialize the panel every time i click on the skills? (so before if i have 10 skills i have 10 panels, now i have 10 skills and one panel)

cobalt bloom
#

I'm guessing not exactly since it looks weird

image.png
#

using view space instead of world space makes it look a little better but its still weird

image.png
stone pewter
#

there might be a setting to change the output normal space

#

if so, change it to world
