[gray mural]

first of all you have TextMeshProGUI, you need TextMeshProUGUI

[leaden ice]

is this supposed to be UI or not?

oh yeah also this is just a compile error

because you spelled the class name wrong

[half sparrow]

I just want labels on my tiles. For example tile at position x=0 y =0 will have the label 1 and so on (2,3,....25)

[leaden ice]

you need to decide if this is UI or not and give it the apporopriate components

there's also no reason to be calling AddComponent

just put the appropriate components on the prefab

[leaden ice]

are your tiles UI elements?

or game world objects

[half sparrow]

gameobjects

[leaden ice]

everything is a GameObject

are they UI or game world objects

[gray mural]

it cannot add one more TMP_Text

[leaden ice]

if they're not UI, don't use UI stuff like TextMeshProUGUI

you can use the game world version of that - TextMeshPro

[leaden ice]

this picture tells us little

because we can't see whhat components are on everything

but assuming it's not ui...#archived-code-general message

[gray mural]

yes, you need TextMeshPro - Text

[AddComponentMenu("Mesh/TextMeshPro - Text")]

public partial class TextMeshPro : TMP_Text, ILayoutElement { ... }

this is for non-UI GameObjects

[half sparrow]

Let's forget my stuff. Lets assume you want to create a grid 5x5 with tiles (square sprites) and have a label on the middle as number. the first tile has number 1 and the 25th tile has number 25. How am i supposed to do this? Because the text i get is from UI. Right click ->> UI --> Text - TextMeshPro

All this by code only

[gray mural]

you probably want them to be buttons

[half sparrow]

no i dont. I want to be like land where my player will walk

or maybe there is another prespective i cant see

[gray mural]

then you probably want them to be Images with Text - TextMeshPro child

[leaden ice]

well you're picking from the UI menu so of course it's UI

3D -> TextMeshPro

[gray mural]

3d?

[half sparrow]

Would y like to share my screen to see what i have done? Or its not possible right now?

[gray mural]

just share screenshots if it's required

[peak halo]

Yeah that sounds really reasonable thank you so much for the input! I think I am going to sleep on it though and see what I can come up with in the morning. Maybe like a hybrid solution? idk

Anyway thanks a lot! Really appreciated

[ashen yoke]

@half sparrow non ui TMP is in world space

it has a world position if its behind the tile it wont be rendered

[half sparrow]

Now i understood

[ashen yoke]

check position, if its actually anywhere near the tile

[half sparrow]

I used 3D Object --> TextMesh

and now it spawns

i will send a screenshot in a sec

[gray mural]

why do you need it 3D?

[ashen yoke]

tiles are sprites

[half sparrow]

I dont know but in 2d gameobject there is no text

(Generally i am new in Unity)

[ashen yoke]

2d and 3d are both 3d

there are various systems that differ

but essentially 2d is just 3d meshes

so in both the 3d text will function identically

[half sparrow]

Ok thanks guys. Now i have to adjust the location the the color

[echo plaza]

Hey @leaden ice, I finally got it so the rebinding works in game! I made a custom script that adds the new keybinds to the player's PlayerInput. Along with this I edited a bunch of the rebinding sample's scripts to make it so this actually worked. And now I can finally relax and know that my players can change their keybinds if they wish. Also I can add more controls and their rebinding really easily now. Thanks for the help! :)

[hollow hound]

What are common practices for managing subscription for events?

I have player that is spawn in Awake of a spawner after the game start.
I have UI component that subscribes to player events in onEnable.
There is chance that player will spawn after UI component onEnable which results in null reference exeption.

Current realisation:
UI components subscribes to GameManager event onPlayerInit.
Player spawner spawns player in Awake and than invokes onPlayerInit in Start..
That way UI components starting subscription to player events after player is spawn.

The problem is that GameManager is singleton. So to access instance of GameManager it need to complete its Awake. But UI components onEnable can execute before GameManager Awake and nullReferenceExeption again.
How I can resolve this problem?

I don't want to mess with seo.
I want to avoid subscribtion to events in Start, because that way I still should duplicate code in onEnable with kludgy checks.
I want to avoid spawning all UI components (and other thing) by hands in one spawner with specific order.

[ashen yoke]

use event bus for ui

will save you lots of headaches

[modest pawn]

Try DefaultExecutionOrder attribute on gamemanager, awake should e running before any onenable

[ashen yoke]

that will only alleviate some scenarios

i.e. the startup, at runtime you will be running into complex scenarios where observed objects get instantiated, you need to observe it, its components, then unsubscribe in the same order, and keep track of it all

this all is alleviated with event bus conceptually

you dont need to know what you observe UI just receives events from the bus

can subscribe at any point, doesnt matter if the observable exists or not, what order it all stops mattering

[hollow hound]

If understand correclty, GameManager is doing this "bus" concept. It trigers events for ui only after player is created. The problem is that GameManager is monobeheviour sigleton so its instance can be null on Enable of other components.
Should I do similar logic but for static bus class?
Or I should just invoke several events one after another like: playerSpawn, uiSubscribe, etc?

[ashen yoke]

well separation of concerns aside, you can set your GameOverlord high in SEO if its the root system, there are other ways to ensure that it always loads first even before any awake is called but its advanced

[modest pawn]

I understand the pattern, but the observable cant be null when you subscribe to it.

[ashen yoke]

this confuses me

elaborate please

[modest pawn]

It's the lack of order of initialization that puzzles me. Observables have to be not null if you want to sub functions to them. In other words, GameManager must exist. Then some game data like a player must be initialized before invoking the UI events.
Something like InitManager->InitGameData->InvokeOnEvent. If this is not right I am clearly not seeing something.

[compact spire]

If I want a rigidbody to rotate towards a target using torque, I'm guessing I need to do some math between the rotation of the object to be torqued and the position of the target and then.. normalize that value? I can't find too many concrete examples of this besides some implementations of a PID, which is a bit overkill.

[icy pebble]

@ashen yoke considering how many times today you've mentioned "event bus" i'm surprised you don't have a go to "use this" 😆

[ashen yoke]

yes you are missing couple of things, 1 here game manager functions as event bus, but it actually has a lifetime so you are bumping first time into waiting for object to init,
with event bus its always there, 2. the game manager here is not the observable, the player is and the ui needs a way to be notified of when the observable is spawned to hook,
which is alleviated if there is no need to hook into a particular observable, all ui would care is what events it receives to update corresponding parts, ie subscribing to

EventBus<OnPlayerDamage>.Subscribe(HandlePlayerDamage)

wont need an active Player

[icy pebble]

ironically i was trying to find our conversation from this morning my time and that was in #💻┃code-beginner

[ashen yoke]

@icy pebble im surprised myself, this is first time in a long time i had to mention it, and so many times a day in row because people keep coming with the same issue type

[icy pebble]

funny

I'm going to look into https://github.com/NullTale/UnityEventBus (which I had mentioned in the other thread). It looks very complete and is already an importable unity package

[ashen yoke]

i dont like it

¯_(ツ)_/¯

[icy pebble]

do you have one that you do like, or a reason you don't like it?

i have no frame of reference here

[ashen yoke]

looks too convoluted, no clear event naming, strongly typed payload, no arbitrary event sub, too verbose, too many interfaces

i have one that i like its the one i wrote 😄

example

[icy pebble]

https://github.com/PeturDarri/GenericEventBus
this one looks a little simpler but newbiness I am not sure how I would install it

[ashen yoke]

public struct OnPlayerReceivedDamage : IEvent
{
    public float damage;
}
//...
// whole file with clearly named events all searchable by IEvent

class SomeMono : MonoBehaviour
{
      private EventBinding<OnPlayerReceivedDamage> _onPlayerReceivedDamage;
      
      void Awake(){
          _onPlayerReceivedDamage = HandlePlayerReceivedDamage;
      }
      
      void OnEnable()
      {
          _onPlayerReceivedDamage.Listen = true;
      }  

      void OnDisable()
      {
          _onPlayerReceivedDamage.Listen = false;
      }  
    
      void HandlePlayerReceivedDamage(OnPlayerReceivedDamage payload)
      {
          txt.SetText(payload.damage);
      }
}

then somewhere

EventBus<OnPlayerReceivedDamage>.Raise(new OnPlayerReceivedDamage(){ damage = 1 });

minimal baggage, minimum interfaces, they are still there, but simplicity and clarity is what i like, easy to reason about easy to track

[ashen yoke]

much better

[compact spire]

Unity has a built in event system doesn't it? What's the issue with that?

[ashen yoke]

never thought of that, did you know any scenario where it was used as an event bus for arbitrary data?

arbitrary events

[restive hound]

Does Physics.Checkbox check evenly from the origin
(i.e. if casted at origin, bottom would be -2 top would be 2 for a half value of 2)
or does it cast upwards i.e. box would check 0 to 4?

[icy pebble]

It's all arbitrary events. Hangon short YouTube video

https://youtu.be/djW7g6Bnyrc

Does a lot with the editor UI but I assume you can also do a lot in code. Just haven't found a clear example yet.

[ashen yoke]

its unrelated

its is simply a serialized delegate

[jagged rock]

I wonder if there are many people who have played with the new Spline Package and can understand what is causing this issue? https://gamedev.stackexchange.com/questions/206196/unity-spline-animate-reset-the-position-when-change-the-speed

[marble holly]

hey,
if (Application.internetReachability == NetworkReachability.NotReachable) does not working on StandAlone windows il2cpp build, correctly ...
any suggestions?
thanks.

[icy pebble]

@ashen yoke https://docs.unity3d.com/ScriptReference/Events.UnityEvent.html

Looking at this it's a little less flexible than a c# event bus. It either requires a lot of use of the editor UI or still a fair amount of references in your code to other objects to set their listeners. There's not really a clear "bus"

[steady moat]

You did not correctly implement the pattern. When ever you reference the GameManager, this is when it should instantiate itself if it has not.

using UnityEngine;

// <> denotes this is a generic class
public class GenericSingleton<T> : MonoBehaviour where T : Component
{
    // create a private reference to T instance
    private static T instance;

    public static T Instance
    {
        get
        {
            // if instance is null
            if (instance == null)
            {
                // find the generic instance
                instance = FindObjectOfType<T>();

                // if it's null again create a new object
                // and attach the generic instance
                if (instance == null)
                {
                    GameObject obj = new GameObject();
                    obj.name = typeof(T).Name;
                    instance = obj.AddComponent<T>();
                }
            }
            return instance;
        }
    }

    public virtual void Awake()
    {
        // create the instance
        if (instance == null)
        {
            instance = this as T;
            DontDestroyOnLoad(this.gameObject);
        }
        else
        {
            Destroy(gameObject);
        }
    }
}

https://awesometuts.com/blog/singletons-unity/

[simple egret]

A little side note, as the conversion to T in Awake is never supposed to fail, a hard-cast should be used.
instance = (T)this;

[hollow hound]

So my UI onEnable is fired and it trying to subscribe to GameManager event, GameManager instance is created.
Then GameManager's Awakt is fire and it destroys itself.
Am I missing something?

[steady moat]

Why would it destroy itself ...?

[hollow hound]

Because

if (instance == null) {... }
else Destroy(gameObject);

[steady moat]

Instance would be null at the moment of the awake.

instance = obj.AddComponent<T>(); will only set after the Awake OnEnable

[hollow hound]

We can't know this for sure.
It was accessed before its Awake so the instance is already created.

[icy pebble]

@ashen yoke watched a few more videos. Unity events are pretty tied to the editor and would be hard to use in very large or complex projects. A bus system is probably better for what I'm ultimately doing.

[steady moat]

No, the instance is created then assigned to the instance field while you are doing the Get of the Instance

[hollow hound]

And then its Awake is executed and it destroys itself because of if(instance) destroy()

[steady moat]

 if (instance == null)
        {
            instance = this as T;
            DontDestroyOnLoad(this.gameObject);
        }

Where do you see the destroy ?

instance is null at this point.

[hollow hound]

else Destroy(gameObject);

[steady moat]

It will not do the else...

If it is null.

instance is only set after the component as been initialize.

Which happens in the line instance = obj.AddComponent<T>();

Which is kinda redondant though.

[hollow hound]

But its not null because it was accessed from another class before its Awake. And by accessing it, instance was created, right?

[steady moat]

because you assign it also in the awake.

[steady moat]

It is null at this point... It is no more null whenever the call to Instance is done.

Do you understand the difference between instance and Instance ?

[hollow hound]

Yes

[steady moat]

Then, you should understand that instance is null in the Awake while we do the call to Instance.

Ask yourself, when is instance set ?

Would the Awake run before, or after it is set ?

[hollow hound]

I thought here:
instance = obj.AddComponent<T>();
Am I wrong?

[steady moat]

AddComponent will make the Awake call before returning.

[hollow hound]

Oh, I totally missed this part

Thanks

[hollow hound]

But the final Singelton can be not the one the scene had?
Because after accessing Instance, the new Singleton will be created.
And when the old Singelton's awake will execute, it'll destroy itself. But at this point we already have new Singleton.
Right?

[steady moat]

Usually, you do not have a singleton inside the scene. It is created at runtime.

If you need serialized data, you use a prefab that you instanciate.

With the usage of Resources.Load

[warm geyser]

Hey I have a general logic question, I have a set of 3 options that can be picked in any order, I just need to figure out whatever the 3rd option is that the first two options aren't. Ideally without just spamming if/else statements. So for example, let's say I have 3 options:

Apple, Pear, Banana

And for my first choice I pick Apple, and for my second choice I pick Banana, the third choice will HAVE to be Pear.

Likewise, if my first choice is Banana, and my second choice is Pear, my third choice by default will be Apple.

Basically what is the easiest way to do process of elimination on the final choice in a table of 3 data elements

[steady moat]

Also, note that the instance in the scene will not be destroyed.

[steady moat]

Use a dictionary and remove element from it.

[hollow hound]

I thought in this case Awake of the old Singleton in the scene will see that instance is already set by the new Singleton that was created by accessing Instance.

[steady moat]

It will not be already set if it is instanciated before

However, if someone else does the call to Instance before it is. It will be destroyed,

[simple ridge]

Hi everyone, just wondering how would I go about subscribing an Action<bool> to a UnityEvent<bool>? The action is being set using a lambda expression that i want to have the ability to remove the listener or change it at a later date. Is this possible?

So far tried it and am getting the error, System.Action<bool> is not assignable to parameter type UnityEngine.Events.UnityAcrion>bool>

[steady moat]

https://docs.unity3d.com/ScriptReference/Events.UnityEvent.AddListener.html ?

[hollow hound]

The old instance that was in the scene, right?

[steady moat]

It depends on the order of the call.

[simple ridge]

Do they have to be UnityActions? And not just normal actions? Ots fine if so, just wondering as normal actions seem interchangeable with lambda expressions, and just placing in the function itself.

I assume some conversion is going on under the hood but surprised that actions on there own don't work is all.

[steady moat]

Maybe not. However, I would surprised. Try new UnityAction(MyAction)

[hollow hound]

Currently I have GameManager(singleton) on the scene that is holding list of characters. Some buttons are created for starting screen based on this list. After character selection new scene is loaded and player is spawn based on GameManager.CurrentCharacter.
What would be better approach to this?
Should I move these lists to scriptable object and loading them with resource.Load in GameManager?
Should I remove GameManager from the scene and spawn it somehow when the game starts?

[warm geyser]

Thank you

[steady moat]

You should have a prefab that contains a component GameManager with the list of your ScriptableObject that is loaded instead of the new GameObject/AddComponent.

[simple ridge]

That does indeed seem to work! Thank you ^-^

[blazing smelt]

I made a custom package and imported it, but the project doesn't recognise my namespace. How would I go about solving this?

[versed marsh]

Hey, I'm trying to get this very specific vector from two points but im not exactly sure how. I tried visualizing it using this terrible graphic if it helps at all, but I'm honestly not sure where to start.

[buoyant crane]

looks like you can get the direction of the line from planet.position - sun.position and use https://docs.unity3d.com/ScriptReference/Vector2.Perpendicular.html to get the line perpendicular to it

[lean sail]

if its 3D, you'll need some other factor to determine which way that line should point. Because you could rotate that desired vector around the imaginary line and each rotation would still be perpendicular

[versed marsh]

Right, I think I'm gonna just make a vector2 for the sun and for the planet only using the axis' i care about

[upbeat hill]

Hey guys, I'm messing around with the 3D Game Kit, I'm trying to add another transition from Idle to Ellen getting her weapon out. I've set a parameter IsAiming to false by default and I'm trying to trigger the animation by pressing the right mouse button and setting isaiming to true but it does not work =/

Looking at the PlayerInput/PlayerController, there is so much there that it gets overwhelming pretty fast to set a simple animator transition

I'm making progress on understanding those scripts, I feel I'm getting close, but no luck so far, hmu by @me if you're interested in the matter

[limber agate]

You could very easily find a beginners tutorial on how to do animations

Is there smth I'm missing?

I want to search for every document inside of 'mails' but this is not finding any document (using Firestore Database)

await mailsRef.GetSnapshotAsync().ContinueWithOnMainThread(task =>

        QuerySnapshot mailsQuerySnapshot = task.Result;
        Debug.Log(mailsQuerySnapshot.Documents);
        foreach (DocumentSnapshot documentSnapshot in mailsQuerySnapshot.Documents)
        {

}

[versed marsh]

Thanks so much for your response, I ended up with this (inside FixedUpdate) and it works just as I needed

Vector2 orbitPos = new Vector2(transform.position.x, transform.position.z);
Vector2 planetPos = new Vector2(planet.transform.position.x, planet.transform.position.z);
Vector2 dir = Vector2.Perpendicular(planetPos - orbitPos);
Vector3 velocity = new Vector3(dir.x, planet.rigidbody.velocity.y, dir.y);
planet.rigidbody.velocity = velocity * planet.rotationSpeed;

That being said, I am now encountering this strange issue where the planets seem to get farther and farther away from their respective orbit points, and I'm not sure why

[steady moat]

You know, that if you simply add an acceleration towards the planet you gonna end up with an orbit ?

Given an initial speed

[wind palm]

Perhaps I am missing something but you're using physics (Rigidbody), but not using physics maths.

[compact spire]

So I'm intermittenly getting an excepton when I run my project. It makes me think that I have a race condition when looking up gameobjects/components before they are initialized, but I'm not sure how to isoalate it down. ArgumentNullException: Value cannot be null.

I just realized that debug isn't automatic in Rider....

I'm used to VS where the swap between debug and release dictates whether or not what happens when you click build and run.

I had Rider set to "attach to unity editor and play" and then I would hit the play button thinking that I would get a break point on exception. I didn't notice the little debug button on the right.

[dapper schooner]

QQ, Is it required to rebuild my unity app every time I create a new addressable post release? Even if the app already has the buttons setup to download the new addressable by name.

yo I have this script that makes a dictionary of classes inheriting from element https://pastebin.com/jWnWR0bg, however,

im getting a "NullReferenceException: Object reference not set to an instance of an object" error on the first line of the constructor of the first class it runs line 36 on
if (Activator.CreateInstance(type) is Element element)

this wasn't happening before a slew of changed i made so some other underlying logic but now of that logic effects this script of the element's constructors so I have no idea why its happening now.

am i not allowed to run Activator.CreateInstance(type) in a static method?

[compact spire]

maybe

load the assemblies before attempting to create the instances?

[rugged storm]

actually wait small development, it seemingly with the base element class

but nothing that derives from it

[compact spire]

Is element derived from anything?

[rugged storm]

wait wtf, IT ALL WORKS NOW

maybe it was just a build error in unity and no element is just a class of it's own

i literally just commented it all out then undid it, thats all ive done...

Would TextMeshPro questions go here?

@cobalt gyro your trying to raycast against a layermask that the parent object is a part of?

yes

Hi everyone, I was hoping someone could help with with a solution for copying the entire state of an animator and pasting it into another. To explain, I have an animated model that can be replaced during runtime, however the model has some level of animation running on it that I want to preserve. Since the way its set up means destroying the game object, and then respawning a new "almost" identical copy with the same animator (though somewhat nested in the heirachy from the base prefab) I want to copy the state of the animator before the deletion and then replace it on spawning in the new object. Is this even possible?

anyone could comment on this? https://discord.com/channels/489222168727519232/1123808863272050779

[cobalt gyro]

The problem will likely still persist since most objects that will call this function will have a target on them

[soft shard]

When you say "state", do you mean the progress/time of the currently playing state or literally generating new states in a new animator at runtime? To do the latter would require Editor-only code, so you wouldnt be able to make a build using it, If you want an "amost identical" copy at runtime, it sounds like you could just duplicate whatever animator controller your using, and make your changes there, and put the different controllers in an array to select from if you need more than 1 "almost identical" change, but I may not fully understand what your trying to do

[void basalt]

I've done this on a network level.

For each animator, you'll need to pack up the amount of layers, and for each layer, you'll need to pack up the currently playing animation state ID as well as the normalized time.

For my case, transitions didn't work because I needed to replicate exact single frame snapshots over and over. This didn't work for me because the transitions need to complete before the next state starts

But if you can allow the transition to fully complete every time you need to replicate it, then it's probably going to work fine.
You can use the Animator.Play function to resume the states. Check it's overloads.

[tiny mantle]

https://gdl.space/okukapekoc.cpp

this logs that escape has been pressed, but it doesn't pause or resume

[dusk apex]

Put logs in pause and resume.

[somber nacelle]

are you certain you've assigned an object to the pauseMenu variable and are not perhaps getting a NRE?

[dusk apex]

Btw, the escape character unfocuses the Unity Editor if tested from the Unity Editor.

[tiny mantle]

can I get it to focus?

[dusk apex]

It'll only happen in the Editor and web builds, other builds will be fine. Maybe use a different key in the Editor.

This might not be the issue you're having but it should be something you're aware of as you test your game

[tiny mantle]

I tried changing it to Tilde

strill didn't work

[dusk apex]

Did you try printing in resume and pause?

[tiny mantle]

I put in Debug.Logs in pause and reumse statements and they aren't being logged, so it isn't going into the statements

[dusk apex]

Likely at least one is occurring if the outer is print.

[tiny mantle]

if (Input.GetKeyDown(KeyCode.Tilde)){
            Debug.Log("Pressed escape");
            if (GameIsPaused){
                Debug.Log("Resuming");
                Resume();
            }
            else{
                Debug.Log("Pausing");
                Pause();
            }
        }```

[dusk apex]

Show the console tab.

[tiny mantle]

there is nothing

[dusk apex]

The object isn't active or the window doesn't have focus.

Or the component isn't in the scene.

[tiny mantle]

so that would only leave the object being inactive

This inherits from another class wich hold a few values:
```public class Values : MonoBehaviour

    public string[,] buttonText = new string[3, 10];
    public int[] buttonProgress = new int[3];
    public int progressSlider;
}```
I have no idea what is wrong with this can somebody please help me.

[somber nacelle]

where do you assign an instance to stageMissions in your SliderBehaviour class?

[lapis sierra]

In gameDefinition right?

[somber nacelle]

that's a different variable with the same name. i'm referring to the one in SliderBehaviour which is where your error is, no?

[lapis sierra]

currentValues = stageMissions[GameDefinition.currentStage, GameDefinition.currentMission];

that's accessing stageMissions, that is not assigning to it

[tiny mantle]

also if you are going to put code into here, you can add syntax highlighting

Console.WriteLine("Hello World!");

[lapis sierra]

I dont assign it i can see

[somber nacelle]

exactly

that means it is null

[lapis sierra]

public void DeclareVariables()
        {
            currentMission = 0;
            currentStage = 0;```
If i put it like this it still doessnt work.

[somber nacelle]

huh? that's irrelevant to the issue. the array is null

if you want it to be a reference to the array on the GameDefinitions class then you need to assign it to that object stageMissions = gameDefinitionRefrence.stageMissions

[lapis sierra]

Omg that fixes that Isue thank you! But it brings out another one.

NullReferenceException: Object reference not set to an instance of an object
MyGameNamespace.SliderBehaviour.UpdateProgress () (at Assets/Scripts/BetterScripts/SliderBehaviour.cs:44)```
It says that it is in this snipped:
```cs
           
foreach (int indexValue in currentValues.buttonProgress)
            {
                currentValues.progressSlider += indexValue;
                totalProgress += indexValue;
                Debug.Log(indexValue);
            }```

[somber nacelle]

which is line 44

[lapis sierra]

oops

foreach (int indexValue in currentValues.buttonProgress)

That line

[somber nacelle]

then either currentValues is null or its buttonProgress variable is null

[lapis sierra]

Debug.Log(currentValues);
this give Null with uppercase. That is difrent from null right?

[somber nacelle]

that's unity's fake null, but that does mean that is the object that is null

[lapis sierra]

But we just assigned it

            if(currentValues != null)
            {
                currentValues = stageMissions[GameDefinition.currentStage, GameDefinition.currentMission];
            }

[somber nacelle]

keep in mind that you only assign to the first index of your 2d array. if those two ints you are using to index it are not both 0 then of course it will assign null to the variable

GameDefinition gameDefinition = new();
well that's a problem. this object is a MonoBehaviour. you should not be using new to instantiate a MonoBehaviour

[lapis sierra]

Ow in DeclareVariables?

[somber nacelle]

yes

[lapis sierra]

But it is in an inheritance does that make any diference?

[somber nacelle]

it's literally inheriting from MonoBehaviour. that is the entire issue with that line. does this object need to be a component in the scene? if not, then don't make the Values class inherit from MonoBehaviour

[lapis sierra]

No it does not have to I think

[somber nacelle]

of course that's only going to fix part of the issue. you'll still need to populate the rest of your array at some point

[lapis sierra]

It gives some other errors now

Assets\Scripts\BetterScripts\SceneCreatorTasks2.cs(65,50): error CS0311: The type 'Game.GameDefinition' cannot be used as type parameter 'T' in the generic type or method 'GameObject.AddComponent<T>()'. There is no implicit reference conversion from 'Game.GameDefinition' to 'UnityEngine.Component'.

[somber nacelle]

well of course, it's not a component anymore so why are you adding it as a component?

if it needs to be a component, then you have to use AddComponent to create an instance of it at runtime and it needs to inherit from MonoBehaviour again

[lapis sierra]

you are right

I dont think it has to be an component

It was a way to assign it to a reference so i could use itsfunctions

How can I assign the script to a variable? gameDefinitionRefrence = gameObject.AddComponent<GameDefinition>();

[somber nacelle]

you may want to rethink what exactly is happening here and what you are trying to accomplish with it

[lapis sierra]

Good idea. I think i have gotten too deep into it.

[simple ridge]

Ah this could work. Ideally transition would be usable but if nit then its not the end of the world on my part. How would you convert the currently playing states Hash ID into something usable for the .Play function? From what I've seen you need the string name for that but 'GetCurrentStateInfo' seems to only give hash integers.

[oblique spoke]

There is a hash version https://docs.unity3d.com/ScriptReference/Animator.Play.html

[void basalt]

https://docs.unity3d.com/ScriptReference/Animator.CrossFade.html You'll need this to play transitions also

Hi!
I have a Cinematic property (sentence.cinematic) on a DialogueManager script, and it's working perfectly.
On game loading (if the player quits during a dialogue), the dialogue get back to the beginning, so I need to set the Cinematic property again. When I do that, and I try to active the cinematic gameobject, with sentence.cinematic.gameObject.SetActive(true);, I get an error, because sentence.cinematic is null, but it's appearing on the inspector (capture below).

This is a strange comportment, do you have any hypothesis?
Thanks!

(please mention me along with your response)

[prime sinew]

Check that there aren't 2 DialogueManagers, one with a null cinematic

You can check by typing
t:DialogueManager in the hierarchy search bar

[bold flare]

Nope, only one

[prime sinew]

You searched with the t:, right?

[bold flare]

yep

But i found

I was writing my message

"Oh, ok, I'm dumb-
It was not null on my DialogueTrigger script, but it was on DialogueManager. It's difficult for me to explain it, cause I'm french, but if you want I can explain you the situation. Thanks!"

[dim gust]

hey i am trying to move the player away from a point where a ray hit but my issue is that the player is moveing away from the ground and into the void, how can i make it move up ?

[merry shore]

make what move up

could do transform.up

[dim gust]

the player -_-

[merry shore]

transform.position += transform.up * speed * Time.deltaTime

[dim gust]

lerp would be better bc is smoother

[dim gust]

but that works too, thanks

Good morning!

I need to set a variable when the game loads. This variable is of type Cinematic, and accepts a lot of classes heriting from "Cinematic". For example, I would like to set this variable to a script called Cinematic_e1c1. I can't use .Find (and don't want to), and the gameobject on which the script is attached is inactive on game launch. What's the solution?

Thanks!

[spice cave]

Hey!
How would i implement Spline points to perlinValue?
Lets say -1 to 0 goes from y = 80 to 100

[gray mural]

Is Cinematic Unity's built-in class?

that doesn't matter anyway

As I have understood, you have problems with accessingCinematic_e1c1 reference, right? @bold flare

[bold flare]

Nope, it's a class I made.

[bold flare]

Yes. The problem is that the gameobject on which the Cinematic_e1c1 script is attached in set to unactive. So I can't find a way to find it by name or id.

Cause in my save file, the solution I found is to save the component ID or name in a string.

[gray mural]

yes, you can set this gameObject with [SerializeField]

it's the best solution

unless your script is on prefab

[bold flare]

Wdym?
If I set the SerializeField attribute, then what?

[gray mural]

just normal [SerializeField]

and you set your GameObject

you have said it's inactive

so it's in the scene

you can set it easily then

[bold flare]

But I can't

[gray mural]

you do something wrong then ??

[bold flare]

The cinematic variable change everytime. When the game loads, it isn't set. It's the job of my save loader to set it.

[gray mural]

I don't get it

if you set it somewhere - it gonna be changed afterall

it doesn't make sense

[bold flare]

Probably due to my bad english, sorry..

Ok, let me explain better..

[gray mural]

try to explain

oh.

I have sent you friend request by mistake

[bold flare]

np

[gray mural]

was just looking on your profile

don't mention, just decline

ping me when you finish explaining

[bold flare]

I have an Animal with my Cinematic_e1c1 script attached.
On a pickable object, I have a DialogueTrigger script that will start a dialogue and the cinematic when the object is picked up. So here, I've set the "Cinematic" manually, like on the screen below.

On game quit, I need to save all the dialogue informations, to start it again on game load.
In order to achieve that, I get the "Cinematic" variable, and I set it in my save file. Then, on save load, I need to get it and set it back on the "Cinematic" variable of my dialogue.

I think that's better for everyone to understand the situation...

I don't know why I didn't give all those informations before 😅

[gray mural]

So you need to get Cinematic script that is attached to certain GameObject first?

Cinematic savedCinametic;

[bold flare]

To save it, there is not problem. The thing is to get it back from the Animal gameobject, which is disabled on game load.

[bold flare]

Where do you think I should set that? Should I set it before or after game quit?

[gray mural]

when is Animal GO disabled?

it's not disabled in some period of time I guess

[bold flare]

When the game starts (at the very beginning), this GO is disabled. It got activated just before the cinematic begins. When the game closes and open back, the game is like if it was never played, and I have to activate it back to start the cinematic again.

[gray mural]

there is a method to find it even if it's inactive anyway

[bold flare]

Oh? Which one?

[gray mural]

is it ok for you to find it with "tag"?

[bold flare]

I could not be doing the save properly, too-

[gray mural]

or "name"

[bold flare]

I was, for something else, but I can do it again

[bold flare]

Would be better 👍🏽

[gray mural]

do you have many GameObjects in scene?

just try not to do this method in Update

Cinematic[] objects = GameObject.FindObjectsOfType<Cinematic>();

you need to find objects of type Cinematic first

then you can use any kind of loop

I prefer using LINQ's First()

[bold flare]

I will do it once, only on save load

[gray mural]

cinematicObject = objects.First(w => w.gameObject.name == "Blabla");

[bold flare]

🤔

[gray mural]

using System.Linq;

you know this I hope ??

[bold flare]

So, this is supposed to work with unactivated objects

[bold flare]

👍🏽

[gray mural]

oh, wait, I forgot smth

Cinematic[] objects = GameObject.FindObjectsOfType<Cinematic>(includeInactive: true);

[bold flare]

Oooh-

Ok

Let me check the doc

[gray mural]

you just do it in 1 line

cinematicObject = GameObject.FindObjectsOfType<Cinematic>(includeInactive: true)
    .First(w => w.gameObject.name == "Blabla");

[bold flare]

Yep

I understand perfectly.
Thank you a lot for you patience and time!

[gray mural]

docs for linq or method?

[bold flare]

The method

Alright!

So I just need to convert my "Cinematic_e1c1" (deriving from Cinematic) to the Cinematic_e1c1 Type.
Perfect, thank you again!

[gray mural]

yeah, hold on

[bold flare]

It's working!

[gray mural]

I have just mentioned

why can't you set it via [SerializeField] ?

there shouldn't be any issues here

oh, wait

no.

[bold flare]

So I save the complete object, and restore it back?

[gray mural]

sorry?

I am asking if you can set it via [SerializeField]

or am I missing something?

those are not the same objects

you have gameObject with Cinematic class in your scene

you just drag it into [SerializeField] property

[bold flare]

But this means I have to do it for every cinematic? I mean, I have Cinematic_e1c1, Cinematic_e1c2, Cinematic_e2c1... Probably not the best way to do it, but that's what I wanted to improve today.

[gray mural]

why don't you do array for GameObjects then?

that's the same like with FindObjectsOfType

but serializing them is better for your performance, @bold flare

[rose stream]

ok my question is simple
Can we use static libraries in Unity?

[bold flare]

🤔

(sorry, had to go)

So, I should have a property on my "LoadingManager" (or somewhere else) containing all the cinematics in an array, right?

[gray mural]

yeah

that's just array of Cinematic classses that you set in Inspector

isn't that you need

if you don't want to set them manually - you can also get their parent and extract children

[bold flare]

I could, that's just that I wasn't wanting to add a hundred of cinematics manually. But now that you're talking about this solution, it's true that it can be better for performance to have them here.

[gray mural]

yes, just make them children of one parent and extract

and you should have mentioned that earlier

[bold flare]

Didn't I?

[gray mural]

you didn't

[bold flare]

Oops-
My apologizes

Thank you again for your precious help!! 🙏🏽

I think I'll try to do the array so!

[gray mural]

you need List to set them via their parent

Are there any websites that are like archives or libraries for different algorithms, I want to learn data structures and algorithms but I don’t do well with structured courses, it’s better for me to hop around here and there

.ToList().All(x => somePredicate)

[buoyant crane]

GeeksForGeeks has a nice list of them

youtube

[fleet furnace]

Yeah. GeeksForGeeks with combination of LeetCode I guess to test your knowledge 🤔
Although some GeeksForGeeks articles are better than others.

[fervent furnace]

leetcode contains lots of edge cases
though you can see the test case you cant pass

[haughty pagoda]

Thanks!!!

Is it timed?

It would be nice to research the algorithm as I receive the problem

[fervent furnace]

time limit for c and cpp is 2000ms i guess
i havent tried other language yet

[fleet furnace]

Its not timed but it does not give you the data structed that should be used to solve a particular problem
So you have to be able to google or know them before hand.

You're still nesting the two groups inside each other.

[rare plank]

oh oh bruh

[rare plank]

so something like this? sorry i dont really get what you mean

            GUIStyle areaStyle = new(GUI.skin.box);
            areaStyle.fixedWidth = 300;
            areaStyle.normal.background = AutoDonateGlobals.blackTexture;

            if (showUI)
            {
                // Parent area
                GUILayout.BeginVertical();

                GUILayout.BeginVertical($"AutoDonate v{AutoDonateGlobals.pluginVersion} - by architelos", areaStyle);
                GUILayout.Space(20);

                GUILayout.Label("Accounts");
                bool selectAccount = GUILayout.Button("Select Account");
                bool saveAccount = GUILayout.Button("Save Account");

                GUILayout.EndVertical();

                if (saveAccount)
                {
                    GUILayout.BeginVertical("Enter Credentials", areaStyle);
                    GUILayout.Space(20);

                    inputEmail = GUILayout.TextField(inputEmail);
                    inputPassword = GUILayout.TextField(inputPassword);

                    bool saveCreds = GUILayout.Button("Save");

                    if (saveCreds)
                    {
                        await AutoDonateHelpers.SaveCredentials(inputEmail, inputPassword);
                    }

                    GUILayout.EndVertical();
                }

                GUILayout.EndVertical();

it still has the same issue, by the way

[late lion]

That looks right to me. Your problem seems to be that you're logic is wrong. saveAccount will only be true for one frame when you click the button and then immediately become false.

[rare plank]

hm okay, let me try moving it

[dim gust]

hey, for example i have 3 game object slots in the editor, how do i make that i can colapse them in the editor

[heady iris]

you could make a struct that holds several game objects

you'll be able to fold that

otherwise, you'd need to write a custom editor

[brittle nebula]

How does AddForceAtPosition work? I know what it does but I mean internally, the physics behind it.

[vast patio]

Is it possible to add a function to this GameManager.OnGameStart Action event, where I put in parameters, without adding argument to the OnGameStart event.
I dont wanna write a function for every menu to hide.

[ashen yoke]

yes

() => { ... }

this creates a closure

closure captures variables

[vast patio]

that sounds good, how would I write this?
GameManager.OnGameStart += (_mainMenu) => {DeactivatePanel} ?

[ashen yoke]

you write the way i posted it replacing ... with what you had after +=

[vast patio]

ahh

[ashen yoke]

dont forget ;

[vast patio]

Ty, it works!

[eager fulcrum]

Hey, I'm getting these zenject errors

any ideas what to do with them?

[copper rose]

are you using zenject instead of addressables? and why? 😄

[eager fulcrum]

?

addressables can't do things that zenject can

[late lion]

It seems that something depends on PredictCombat, but PredictCombat also depends on that something, creating a circular dependency. It might not be a direct dependency. It could be indirectly through another type.

[eager fulcrum]

hmm okey

thats weird, I can't find anything

its not a direct dependency for sure

there's just one thing that references PredictCombat

[late lion]

What dependencies does PredictCombat have?

[late lion]

Does the error not include more information about where this circular dependency is, if you click it to see the rest of it?

[eager fulcrum]

i'll send u the whole error

one sec

https://paste.myst.rs/l6rnqaxi

https://paste.myst.rs/uxvz03bx

[late lion]

Okay, something about the SignalBus and BattleUnit. I haven't used SignalBus, so I'm not sure if that can cause this kind of problem.

It seems like you're firing a signal as a BattleUnit is being initialized, which is maybe causing some problems because PredictCombat also depends on SignalBus, but hasn't been created yet. I don't know.

[eager fulcrum]

that's exactly what i'm doing

i'll check if thats a problem later

[simple egret]

The "object graph" in the error is weird though, there's only one item, which makes me think that PredictCombat has a field of type PredictCombat, so it just recurses indefinitely down

[late lion]

Might be a separate issue misidentified as a circular dependency.

[eager fulcrum]

[flint needle]

how can i call a SaveAsset function before exiting playmode?

i try to have a callback to EditorApplication.playModeStateChanged but by that time the instance of the object i want to save is dead

[dim gust]

how can i make this character rotate with the camera

like in thrd person, i use a cinemachine camera

[limber agate]

Youtube tutorial

Look it up first

Before asking

[soft shard]

If this is for the Editor, why not make a button to save in maybe a custom editor window or component context menu, or the top navigation bar, then you can manually click it before exiting play mode - but why might you need to save an asset at runtime anyway? Could you not make it a prefab and "override" the changes you want to keep? (which shouldnt matter if its at runtime or edit time AFAIK)

[flint needle]

im just anticipating. i do have a button for it, i just want a classic "do you want to save before quiting?"

because i have quit without saving, just cant help it sometimes 😅

and i do on runtime cause my tool is on runtime

[dim gust]

i can't find anything if i ask here something

[soft shard]

Fair enough, I would imagine because the play button is pretty much your only reliable way of stopping code execution, it probably cant be "paused" for other code to execute (though maybe theres some API I dont know about that does it), alternatively, maybe you could make a second prefab "clone" when you enter play mode, and just constantly save any changes you make, when you exit play mode, you can then update your main prefab with the clone, or just keep the clone - another alternative would be to create your own "exit play mode" UI button that calls the editors exit play mode, then you can make a "do you want to quit" prompt, but that would mean youd have to break the habit of pressing the exit button which is easier said than done for sure lol

[soft shard]

What keywords have you tried searching for?

[limber agate]

So your telling me if I go on YouTube I wont find a single video on how to make third person

[dim gust]

NOT A FIRST

READ THE QUESTION DUDE

I need an object to rotate to the direciton the camera is looking, in third person

every single video is about MOVEING the player twords the retation

[simple egret]

object.forward = cam.forward - here you go

[rugged storm]

yo question, does flooring a negative decimal = 0??

[limber agate]

Thats not what u asked lmao 😂

[dim gust]

same shit different style

[limber agate]

It literally isnt

[dim gust]

oh no, anyways

[dim gust]

that sents the postion

[simple egret]

No?

[soft shard]

According to the docs, no: https://docs.unity3d.com/ScriptReference/Mathf.Floor.html - if you had like -10.2 then it should just be -10 after being floored

[simple egret]

That copies which direction it's looking in, so its rotation by definition

[rugged storm]

i meant a negative decimal between -1 and 0 btw

[dim gust]

🤝

[rugged storm]

oh so it would then based on what you said why would it not be -1??

[simple egret]

Flooring rounds down, it would be -1 if you had -0.1 for example

[rugged storm]

I think the issue was that i was dividing 2 ints

[flint needle]

i think i will do that thanks

[simple egret]

Ah yeah, integer division truncates without rounding, so in the case of negative number, that would be an equivalent of using Mathf.Ceil

(rounding up)

[rugged storm]

oh god I do that alot in this code I just realized... cuz I use a reference to an constant that's an int and now i gata fix all of that

[dim gust]

this is not doing the trick, the firsts pic is how it suppost to look like

the second is the result

[simple egret]

Looks good to me, it copies the whole camera's rotation

[rugged storm]

Debug.Log($"{new Vector2Int(Mathf.FloorToInt(pos.x / MapChunk.chunkSize), Mathf.FloorToInt(pos.y / MapChunk.chunkSize))}");
in a situation like this would simply casting one of the numbers in each division to flaot fix it?

[simple egret]

If you need it flat, then you should set the vector's Y to 0 in between

[dim gust]

looks good staying the doggy pose, i think something is messed up with the rotation

[simple egret]

You didn't specify that you wanted the rotation only around Y, so I gave you the general solution
Solution is here #archived-code-general message

[dim gust]

the rotation to the parent was not correct, now it works

thanks

Is there a way to simplify this code?

Vector2 GetVec()
{
    Vector2? dir = ...

    if (dir != null)
        return (Vector2)dir;

    return Vector2.zero;
}```

[leaden ice]

This code won't even compile

[swift falcon]

Was it the not all code paths return a value bit? Fixed now

And made it Vector2 since might be clearer than generics

[leaden ice]

I recommend using the TryGet pattern instead of either of the paradigms in this code example (nullable value types, magic values (Vector2.zero) to indicate a missing value)

There's not really any way to simplify that snippet, no

it's quite simple already, no?

[swift falcon]

Thanks, good tip

[swift falcon]

Thanks, the first one there is quite nice I think

First thing that pops into my head is you have a bool on each hex for _checking
Set it to true and then check all surrounding hexes
If it finds a white one then repeat it with that tile and it also sets itself as _checking

If a tile is completely surrounded by red or _checking tiles then set itself to red
Then work backwards through the tiles until you are back at the first

[leaden ice]

You should do a BFS or DFS (basically either as a flood fill) from each white tile to create a list of islands (skip any that you already placed in an island)

pick the biggest island

then turn every other white hex in every other island that is not the biggest and turn them red

You're doing a grid based game without knowing DFS/BFS?

You are going to feel pain

hi

i have an issue with a script

the fastikfabric

script

when it connects to my rig,

it anchors every part of the rig to the ground

of my map

[swift falcon]

For this code (That's not mine):

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SD.Tools.Algorithmia.UtilityClasses;
using System.Collections;
using System.Runtime.Serialization;

    [Serializable]
    public class MultiValueDictionary<TKey, TValue> : Dictionary<TKey, HashSet<TValue>>
...```

These using directives are greyed out in my IDE:
```cs
using System.Linq;
using System.Text;
using System.Collections;```

I'm guessing they are still important because of possible types for the generics?
Let me know if I can remove them

[leaden ice]

psuedocode for what I said before:

islands = empty list
foreach (hex in tiles) {
  if (hex is red) skip
  if (hex is already visited) skip
  island = DFS(hex) // have DFS return all the visited/connected white hexes. It should also mark tiles it visits as visited so we don't waste our time on them later
  islands.Add(island) // dd this island to the list of islands
}

// now find the biggest island:
biggestIsland = FindLargest(islands)
// go through the rest and make them red
foreach (island in islands) {
  if (island is biggestIsland) skip
  foreach (hex in island) hex.color = red;
}```

[leaden ice]

if they're greyed out you can remove them safely

[swift falcon]

Awesome thanks, don't know why there's so much useless fluff in this code

[leaden ice]

The IDE greys out things that are not in use

probably just sloppiness / not cleaning up on the dev's part

[swift falcon]

Anyone got any idea why this custom editor script does not recognize another class?
No namespaces are being used

This is purely in VS though, works perfectly within Unity itself

I want to search for every document inside of 'mails' but this is not finding any document (using Firestore Database)

Example of a Document Path I have:
/mails/DBLG58-RFAJFA-6BFNDT

Code:

CollectionReference mailsRef = db.Collection("mails");
await mailsRef.GetSnapshotAsync().ContinueWithOnMainThread(task =>
{
        QuerySnapshot mailsQuerySnapshot = task.Result;
        Debug.Log(mailsQuerySnapshot.Documents);
        foreach (DocumentSnapshot documentSnapshot in mailsQuerySnapshot.Documents)
        { 
            Debug.Log(String.Format("Document data for {0} document:", documentSnapshot.Id));
            Dictionary<string, object> mail = documentSnapshot.ToDictionary();
            foreach (KeyValuePair<string, object> pair in mail)
            {
                Debug.Log(String.Format("{0}: {1}", pair.Key, pair.Value));
            }
        });
}

This debug logs [ ] and not any of the documents
Debug.Log(mailsQuerySnapshot.Documents);

Log: Firebase.Firestore.DocumentSnapshot[]

[knotty sun]

yes, because Documents is an object and so the ToString of that is it's type

[analog echo]

do you mean this line?
Debug.Log(String.Format("Document data for {0} document:", documentSnapshot.Id));

[knotty sun]

no, the line you showed above

as your object is an array maybe add .Length to the Debug so see thr number of entries

[analog echo]

I tried with Count and got 0

[knotty sun]

Count will not work with an Array

[analog echo]

I'll try

[analog echo]

Debug.Log(mailsQuerySnapshot.Documents.ToString().Length);
With this I got 37

[knotty sun]

no,

Debug.Log(mailsQuerySnapshot.Documents.Length);

[analog echo]

it changes to Count

[knotty sun]

This Firebase.Firestore.DocumentSnapshot[] says its an Array. Arrays have a .Length property

[analog echo]

when Im writing .length and press tab, it changes to Count

[leaden ice]

Is it an array or a list

[knotty sun]

as per the docs
https://firebase.google.com/docs/reference/kotlin/com/google/firebase/firestore/QuerySnapshot
looks like you should be using getDocuments

[analog echo]

ok
https://firebase.google.com/docs/firestore/query-data/get-data?hl=es-419#get_all_documents_in_a_collection
I copied and paste , but i will try with getDocuments

[lean sail]

ive definitely used foreach on it before, but this wasnt in unity

[spark flower]

public class VisionCone : Trigger {

    [SerializeField] GameData data;
    [SerializeField] float range;
    Actor target;

    private void Update() {
        if (target != null) {
            Vector3 _pos = transform.position;
            Vector3 _tpos = target.transform.position;
            if ((_pos - _tpos).magnitude < range) {
                float _angle = Vector3.Angle(transform.forward, _tpos - _pos);
                if (_angle < 45) {
                    data.Alarm = true;
                }
            } else {
                target = null;
            }
        }
    }

    public override void Execute(Warrior _war) {
        target = _war;
    }
}```
any idea how to remove the Update? or atleast optimise it abit, its not vital, but its desirable

[lean sail]

use a trigger collider (not related to your Trigger class), and then only check things when objects are within the trigger

[spark flower]

thats what its doing

its just the trigger event is in the player

[lean sail]

so this isnt a monobehaviour ie Update() isnt called every frame?

[spark flower]

it is a mono

and its called every frame

[lean sail]

then thats not doing what i said

[spark flower]

basically updating alarm while we are in the vision cone

when we trigger a collision enter it runs the Trigger function, which makes it run the code in update,

[lean sail]

my suggestion was basically use a collider (isTrigger = true) instead of doing a distance check

[spark flower]

the range variable is basicly the radius of the sphere collider

collision exit?

[lean sail]

I really dont know what u mean by this

but u should be able to just use OnTriggerXXX then instead of update

[spark flower]

i mean it runs the Execute function

the ontriggerenter event is run in the player

which runs the Execute function

which enables the code in update

but we need to update alarm

[lean sail]

u should still be able to do this with OnTriggerStay() or OnTriggerEnter/Exit then instead, with another collider the size of range to see if the target is within the area.
Or maybe run just run a coroutine to keep going until its not in range

now i understand more of what this is doing, id probably just use a coroutine

[spark flower]

public class VisionCone : Trigger {

    [SerializeField] GameData data;
    [SerializeField] float range;
    Actor target;

    private void Update() {
        if (target != null) {
            if (Vector3.Angle(transform.forward, target.transform.position - transform.position) < 45) {
                data.Alarm = true;
            }
        }
    }

    public override void Execute(Warrior _war) {
        target = _war;
    }
    public override void ExecuteExit(Warrior _war) {
        target = null;
    }
}```
i guess this is the optimisation

is performing 1 Update better then 30?

assuming i will do a loop in that 1 update

to check for the angle

[marble halo]

So im trying to make my camera tilt slightly when i move left or right, but for some reason despite being lerped, it doesn't feel smooth

    void Update()
    {
        movementdir = pInput.actions["Movement"].ReadValue<Vector2>();
        currentinputvector = Vector2.SmoothDamp(currentinputvector, movementdir, ref smoothinputvelocity, smoothinputspeed); //smooths value
        ccam.m_Lens.Dutch = Mathf.Lerp(0, movementdir.x * rotationMax,1f); //applies movement to camera tilt
    }```

nvm

[heady iris]

the third lerp term was 1f, ye

[quartz folio]

You definitely need to understand lerp before trying to use it! https://unity.huh.how/programming/specifics/lerp/overview

[dense estuary]

I dont think i did this right: https://hastebin.com/share/ikevoqahol.csharp How can i get my code to shrink the player gameObject when i trigger the Finish tag.

[quartz folio]

You also need to understand how Lerp works.

Also you can't have an IEnumerator that doesn't yield, so that code won't compile.

Read the Coroutines usage at the bottom of that page once you understand how Lerp works

[dense estuary]

So, I don't know how to fix this. It is shrinking the player gameObject, but its doing it instantly. Here is my script: https://hastebin.com/share/hujocefivo.csharp

ignore the name of the coroutine, I didnt change the name yet.

[tropic quartz]

That's because while loops don't run once per frame. They run as fast as possible.
So you need to add your own pauses there to not make it run at crazy speeds.

[dense estuary]

how can i add pauses?

[tropic quartz]

yield return new WaitForSeconds(3); would wait for 3 seconds.
You can probably do some math to make it frame based if you want to. I've also heard that yield return null makes it wait a frame though It's not really meant for that, I don't think... so I dunno if using it for this would be a good idea.

[quartz folio]

The code already has yield return null in it.

[quartz folio]

Where do you set duration?

[tropic quartz]

Oh wait, you are right.

[dense estuary]

Oh, thats probably the issue, the place that duration is set in line 20 IEnumerator DoShrink(Vector3 endSize, float duration = 1) {

[quartz folio]

That's used if you don't provide a duration, but you are providing one

Line 18 passes duration, which you declare privately on line 9 with the default 0 value.

[dense estuary]

So its setting the scale to 0 imediatly because the time is set to zero rather than 1

[quartz folio]

Yes

[dense estuary]

Thank you, it works now.

I've noticed a bit of an issue where unity SO's don't like interfaces with the inspector and you can't use interfaces with editor scripts...

So I was wondering, all of my scripts inherit from a base class and I wonder in the custom editor if I can create groups depending on if the script has an interace in it?

So for instance my base is "WorldEntity" so thinking if I can handle all variations inside WorldEntity and then use the same Editor script for everything that derives from WorldEntity

So something like... if this is typeof(<interface>) {show properties}?

[swift falcon]

It took me a bit of time to figure this out but...

bool interfaceIExpires = _worldEntity is IExpires;```Seems to be working

[dry jewel]

Hi, this question is for a card game I'm working on. So I have a card prefab in my card collection and deckbuilding scene. It contains certain scripts which do not work outside of the collection scene. I also have a battlefield scene where you duel an opponent. In that scene, in the hand, the cards are supposed to have drag and drop functionality. The the drag and drop is also on the card prefab. If I start the collection scene with this drag and drop enabled, it registers an error because the canvases that it requires are not in the scene obviously.
What is the best option in you guys' opinion to solve this?
Some options I've thought of:

• Different card prefabs for each scene with some overlapping features for the stuff a card always needs.
• Scene checking flag that determines if the script should be on or off depending on the active scene.
• Adding the scripts at runtime and potentially forgoing the start and awake methods for the cards.
• Manager that enables/disables scripts at the start by checking the scene. Not sure how that interacts with the start and awake methods.

But I really don't know what the best option is so what would you guys suggest I do?

TL;DR I have a prefab with scripts that only work in certain scenes, so they throw errors in other scenes. Looking for suggestions on how to fix this.

[gray mural]

so the problem is obviously in those scripts

or not

actually you should do prefabs for 1 scene

thought if you need them to work in other scripts too - add some additional functionality

some ifs

also you have said that canvases that are required are not in the scene

why?

create them in the scene or instsntiate in Start

typing on phone is so bad.

[dry jewel]

Yeah tell me about it, I feel like an unwieldy giant on the phone

So the canvases aren't there because they belong to a different scene.

[gray mural]

You have said that your scripts work in certain scenes. Do you know the reason?

[dry jewel]

Yeah, that I made them to work in that scene. One is a collection/deckbuilder, so it has all the assets needed for those scripts, the other is a battlefield and has the assets that battlefield scripts require.

This also leads to some scrips referencing objects that don't exist in all scenes

Which is where the error messages stem from

But I'm not sure what the most robust way to implement a fix would be

[gray mural]

your issue is obviously in those scripts

you need to fix them or create new

I cannot say more without further context

[dry jewel]

Like what?

[gray mural]

sorry?

[dry jewel]

I'm not sure what else I could say that would be relevant

Like I've explained why the errors happen, I'm just asking on like an architectural level, what's the best fix for a case where you have a prefab in two scenes but it does slightly different things in either scene

And those things it does depend on the contents of the scene

They both need display functionality to actually show the cards, but one does not need drag and drop or any of the object dependencies that come with it, and the other does. What would you need to see to be able to help me?

[soft shard]

Maybe you could add the drag and drop functionality as an additional script or interface, both scenes can create the prefab, if it needs the drag/drop functionality, it can enable that script or call functions from the interface, or you could use 2 different prefabs and maybe inheritance to have "similar but slightly different" functionality, anoher approach could maybe be setting up a script to handle dependency injection if these 2 different scenes just need a reference to exist in the scene before trying to do logic on said reference, you can use the "Script Exection Order" to make sure that injector is the first script to fire

[latent latch]

I'd just disable the functionality and enable it when needed

keep the cards between scenes

[gray mural]

I can do this drag & drop functionality in your script just when XY scene is enabled

[dry jewel]

Do you mean inheritance like prefab variants?

[gray mural]

Like:

if (SceneManager.GetActiveScene().name == "blabla")
{
    // do smth
}

forgot if

phone.

[gray mural]

or you can also make several scripts

actually you can just disable d&d script when scene is XY

other still does work

[soft shard]

I may not have fully understood your case, but I meant inheritance as in something like

public class Card : Mono
{
//card stuff...
}

public class DragDropCard : Card
{
//drag drop stuff...
}

Though it sounds like having a "canDragDrop" bool or similar for Card or an extra script attached to the same object as Card that only handles drag drop events, may be a simpler approach

[dry jewel]

Right so the scripts are separate, they're just both on the same gameobject

Like there's one d&d script, and then some other scripts, what's the best way to disable them for a scene, is it just having a flag check in the script itself to disable it in like the start method or the awake method?

[prime sinew]

Then maybe you should ask in #763499475641172029

[gray mural]

I think yes

that depends on your game actually

just make sure to disable it before it starts executing

there is some window in Unity to do it

[soft shard]

If the card has all these "other scripts" you could have it reference and use functions on the card, some manager that would spawn the prefab could use SceneManager events as friend suggested earlier and call the relevant function(s), for example:

public class Card : Mono
{
[SerializeField] ScriptA a;
[SerializeField] ScriptB b;
[SerializeField] ScriptC c;

public void DoTheThing()
{
a.enabled = false;
b.enabled = true;
//...
}

public void DoAnotherThing()
{
//...
}
}

[soft shard]

Which window are you referring to? Something in "Project Settings" or the inspector for that object or maybe something else?

[gray mural]

I don't have my unity now

There is a window where you can make scripts execute before other scripts

and milliseconds offset between them

I do not remember how it is called

somewhere in project or build settings probably

they can find it

somehow.

[dry jewel]

Oh okay that makes sense

[void basalt]

script execution order

@gray mural@soft shard

https://docs.unity3d.com/Manual/class-MonoManager.html

[soft shard]

Ah, thats what you were referring to

[lean sail]

is it really the ms between them? I think the numbers are just arbitrary

as in only used for ordering

[void basalt]

yeah, arbitrary

[gray mural]

yes, that's it, thanks

[dry jewel]

What if there are prefabs in the scene already that aren't instantiated at runtime. Should I just have like a manager on the card prefab and have that first in the execution order to determine what gets enabled or disabled?

[soft shard]

To me, it sounded like your other collection/deck systems spawn the card prefab, so I would think youd want the manager there, but if its the card itself, you may have to consider if multiple instances of the card is being created, each instance would be trying to do management

[dry jewel]

So the collection looks like this, the prefabs are just there to show the cards and then you can flip pages and it will load new cards onto the prefabs. In the duel/battle scene they are instantiated at runtime, or I guess there could be an object pool already present at the start

Yeah it doesn't need to be on the card itself, that's a good point

[glossy granite]

so increasing fixed time step seems to improve performance in a game , but at what cost?

[thin aurora]

Do you even know what that does?

I highly recommend you do not touch those settings

[glossy granite]

what exactly does?

[thin aurora]

Please read this: https://docs.unity3d.com/Manual/class-TimeManager.html

[tepid juniper]

Anyone have knowledge about ASTC and DXT1-5 formas and texture reading in unity? https://discord.com/channels/489222168727519232/1123808863272050779 Any help would be appreciated.

[thin aurora]

In short, you're basically making it so physics calculations and FixedUpdate() are performed less

So yes, it is a performance increase, because you're effectively breaking your game

[glossy granite]

I have just increased it from .02 to .05 saw a huge performance improvement and saw that enemies were going faster as the only tradeoff

which can be easily solved

ill try leaving it at .02 and see, maybe the game is not that smooth, even if it is still at 60fps

[thin aurora]

Yeah so like I said, this is not the way to increase performance

But have fun figuring that out yourself

If your game performs bad, then you fix the actual code, and not the internal logic or rhytm

[glossy granite]

yep I agree with you, there is not shortcuts 😁

this is were I saw the tip

https://www.youtube.com/watch?v=pTz3LMQpvfA&t=325s

[soft shard]

I would maybe have a look through the Profiler to help find what could be causing performance issues with your project, in "hierarchy" mode, the "time ms" is often related to framerate, and the "GC alloc" in B or KB can often what can cause GC spikes, naturally leading to performance drops, often related to code

[glossy granite]

it think my issue is that I spawning loads of colliders to create walls in planets. Making them basic colliders and static has helped with the calculations.
But another solution could be to activate the gameobjects only when the player is near them

[drifting crest]

I wanna render webcam texture on a plane but when I am doing it , it is showing black screen only I have vuforia package in this project , when I tried to do this in an empty project with same code it's working , SO is there a way I can do it in the first project?

[opaque lodge]

hey guys, i have this situation: i have built the project once, is there a way to not have to do a clean rebuild on the whole project when i only made small changes. just for better debugging purposes

[latent latch]

delete previous files and rebuild

oh to not?

if you're compiling il2cpp, it usually is much longer than mono for one, but you shouldn't have to recompile the whole project for making small changes usually

[south violet]

Hey, Im using CSVHelper.CSVWriter and I am writing a float to csv and for some reason sometimes this written float in csv has 12 decimal digits. How is that possible?

[terse stag]

Hihihi! I just started Unity and I can't figure out how to achieve this:
I want to have a generic way to store data persistently (saving and loading the game) that I could convert to and from json, with reusable keys such as HEALTH, which could be applied to any animal/plant/item, etc...
This led me to a Dictionary<Stat, double> (Stat is an enum) which is fine I could definitely serialize this, but what if I want to store an integer? That's still doable, but annoying... But! What if I want to store a string? What if I want to store another object? Or a class, perhaps a Buff Instance for an animal?
It'd also be nice if possible to have them accessible in the editor
Am I over-engineering this? I know JsonUtil can convert classes to json, but that has also been a pain as it almost Never actually takes any of my fields...
I've been coming across So many dead ends, with no perfect solution... If you have any suggestions, please do ping me!

Oh and I have Odin Inspector if that becomes relevant!
Thank you!

[rain crater]

Hey, how do I draw a box, that I can click on in scene view and call some event? This is for an editor script.

[verbal cliff]

a UI button?

[rain crater]

That could work, but I was thinking more of a 3D box

well, cube, I think

[verbal cliff]

if you want in 3d space you can line trace from where you click straight from the camera. This could then hit the cube and trigger an event.

[lean sail]

You can have some interface to denote things are Saveable. Each class u wish to save data from just implements this interface.
One method can just return object, each class returns whatever they want then. And since its class specific, when you load the data, you already know what the type is.
A SaveManager (or whatever you call it) would take the object returned from the method and just directly save to json

[rain crater]

Can this be done without making a new object for the cube however? Like, just draw the cube and make it clickable, without making it a GO. Or am I overthinking it?
Thing is, I don't want to make a ton of gameobjects for one situation, then delete them right after that. Even though it's just an editor script, it's better not to make it too terrible

[verbal cliff]

the cube to exist in the word will need to be an object or at the very least a component

[rain crater]

Alright, thanks

[rain crater]

Okay, i've found a thing like Handles.CubeHandleCap, and it seems like it might be what I need, but now here's the question, how do I draw Handles.Button for X objects at once?

[stark sinew]

    Handles.DrawButton(...)```

[rain crater]

Ok, but then how can I attach a function to that button? Normally I do it by putting the button inside an if, but if I do foreach and then if, it doesn't work

[stark sinew]

what means "it doesn't work"?
Happy to help, but need some context what's actually happening

If you're changing the object or the collection from inside the foreach loop, I'd advise to using a for loop instead

[rain crater]

Like, the buttons don't show up in the scene view

[gray mural]

because you haven't instantiated it

[stark sinew]

Haven't instantiated the Handles.Button? 8)

[stark sinew]

I think Handles.Button needs a Rect where it will be shown, but not too sure

Gimme a second to check API

[gray mural]

are they not talking about UnityEngine.UI.Button ?

[rain crater]

this is a part of code that I have

foreach (PathPoint _pp in nodeObjects)
{
    if (Vector3.Distance(_script.points[0].GetGlobalPos('p'), _pp.GetGlobalPos('p')) < 25f)
    {
        Debug.Log("Kurde mol");
        if (Handles.Button(_pp.GetGlobalPos('p'), Quaternion.identity, 10f, 8f, Handles.CubeHandleCap))
        {
            _script.AddPoint(_pp);
            isAddingPoint = false;
            break;
        }
    }
}

[stark sinew]

And that is why you first read, then write 🙂

But tbh, this is probably the wrong channel for editor stuff (and for UI stuff as well)

[rain crater]

no, I mean Handles.Button, as it's for the editor script

[stark sinew]

Also, if none of your buttons are showing up, remove the if (distance...)
just for testing

Make it work first, then built on top of that

[rain crater]

it seems like removing the if(distance) helped

but that's weird, because my very specific debug message was being called

ok, and now when I've made one if with two conditions, it works

[stark sinew]

If you just iterate over your path points and draw a button for each, without any other conditions, does it work as it should?

[rain crater]

yeah, as I wrote. Even if I put the distance condition in the same if as the Handles.Button, it also works as it should

Weird but ok, I can work with that

Thanks for help! 😄

[stark sinew]

Also, may I ask what exactly you're trying to achieve? Every path point has to be 25 units away from _script.points[0] but theoretically the path points themselves could all sit in one place?

You're welcome, glad you got it solved for now!

[gray mural]

Does anyone know what method in Unity's TMP_Text or TextMeshProUGUI classes wraps the last word on the next line, when line's width exceeds max width, or returns it on the previous line when character is deleted?

I really cannot find it.

But I need to find it.

I need to see when last word is wrapped and transfer this word into other TMP_Text, not next line

[rain crater]

every path point should be 25 units away from the first path point. This script is used to easily add points to intersections (instead of adding them manually to a list)

They can all sit in one place, but that would be weird, since that would mean a path with 0 distance

[amber depot]

hi guys, I have a small question and a problem lets say like that

[main zenith]

Hi there, could anyone perhaps please help me out with the Furioos SDK if anyone is perhaps familiar with that? We're trying to upload an HDRP project as a render streamed execution but we want to be able to call functions on the browser from Unity and vice versa using both the Unity SDK and JS SDK. We've attempted using the interactions with browser scripting which is a webgl method, but just for testing and that did not seem to work. How can we go about calling these desired functions in this way?

[amber depot]

so I have a GameManager, where I am unsing the Singleton pattern and I am calling a Variable of type GameObject from this script to a script which is attached on my main Camera GameObject, but the instance is always empty when called in the script which are attached to the Main Camera GameObject. I am using VS as my IDE and using breakpoints I came to know that the scripts attached to the Main Camera GameObjects are always called first that any other in the Scene. So is it true for all and is default in Unity or is it just the way the Project is setup

[leaden ice]

Your question is a little hard to follow but if I understand correctly you're asking about which scripts run first?

It's essentially random. For initialization code you should follow this rule of thumb:

• initialize yourself in Awake ()
• initialization that depends on other objects being set up already goes in Start()

[amber depot]

mm ok the I am going to set my instance to my singleton value in Awake

and see what happens

[leaden ice]

That's the standard practice for singletons, yes

[amber depot]

Thanks

[golden flume]

Hey, i would like to make an damage zone like in battle royal game. I have try with a sprite and reduce his scale, but the probleme is i can't make it random. In 2D.
Do u have idea how to proceed ?
Because with a sprite who is reduce over time, player will know where is the center of the safe zone

[jaunty needle]

Hello guys

So I'm trying to make a level loading system much like Undertale's

Wher eyou have differnt rooms and there is a transition between them

Now I wonder which is the best approach, to have multiple tiny scenes and load between them, or one giant scene and do scene transitions between areas, or a combination of both

Because if I had a scene for every room the number of rooms would be gigantic

[mossy shard]

tiny scenes

for the different sections

when in like snowdins , the houses should be in the main scene

with the transitions

in bigger places, another scene

[jaunty needle]

wdym the houses should be in the main scene

[tropic quartz]

Unless I remember wrong Undertale's transitions are just a little camera fadeout before it loads the next area?
Which should be really easy either way.
If it was more like Zelda dungeons (with screen scroll) that'd probably be a lot trickier.

Undertale is a Game Maker game and it probably just has all areas as separate scenes/levels or w/e that engine calls them.

[jaunty needle]

Ah so separate scenes alrighty

[tropic quartz]

What mihnwq probably meant is that in a lot of RPGs it'd probably be more optimal to have shops etc. as just a part of the same scene.
Door could be a teleport and the shop's insides could just be off the map in the void.
That way the game doesn't need to constantly unload/load stuff.

But I wouldn't overthink that stuff if it's a little solo project.

[jaunty needle]

oooh

I didn't think bout the teleport thing

[vivid wind]

It depends on your needs, keep in mind, that by default all loaded data in a scene is unloaded during scene change. So You'll need to be marking stuff as DoNotDestroy or reloading it on scene load. So that should be a consideration when deciding between doing a one large scene or multiple scenes.

[jaunty needle]

Yep yep

[uneven monolith]

Hey! quick question; if i have

Vector2 forward```
and i want to instantiate object facing to that direction, can i just use the forward vector as Quoternion or what kind of maths i have to do(i hope not very complicated ones lol)

ps. i have no idea how quoternions work so googling was ewwhhh

[tropic quartz]

Vector2? Is this a 2D game?

[uneven monolith]

ye

and it doesnt matter that much if it goes 90/180 degrees to wrong direction or another, i can deal with that kind of stuff myself, just like so it orientates depending on the vector2

actually google helped me already with right words

atleast i hope that works

[tropic quartz]

I'm not entirely sure what your Vector2 forward is, but there's Transform.LookAt that makes an object face a target.
If that Vector2 is already the correct rotation then you could just set it's values directly to the transform, though.

[heady iris]

yes, you can produce a rotation (a Quaternion) from a vector using LookRotation

Note that LookRotation defaults to using Vector3.up as the "up" direction. This could cause some weird rolling if you also happen to put in Vector3.up (or Vector2.up)

I suppose you should use Vector3.forward as the "up" direction to keep it consistent

the titular use of Quaternion.LookRotation is to...get a look rotation

in that case, you want the camera to be upright

no roll around the local Z axis

[wise escarp]

Hi, I'm using Mathf.Abs(0 - transform.rotation.z) to get a value between 0-1 between 0-180 degrees rotation
At 90 degrees rotation, the middling value is 0.7 instead of 0.5, despite 0 degrees returning 0 and 180 degrees returning 1. I'm sure I'm misunderstanding something here, how do I get this more exact?

[knotty sun]

rotation is a quaternion not a euler value

[mossy shard]

LookAt or LookRotation may cause some bugs if close to the target

it is better to change the forward direction of the object to the target by calculating the diff of the positions

[atomic iris]

hi im having an issue where im creating and assigning a render texture to a raw image via script. I turn that render texture into an asset in the project as well. when i enter play mode for the first time it works fine, but after exiting the texture for the raw image gets set to none. This isnt an issue if i manually assign the asset from the project window to the raw image but im trying to automate that process a bit and im wondering why the raw image is getting reset

[wise escarp]

Fixed and working the way I want, thank you!

[cold egret]

- I'm working with localization and stumbled upon custom startup locale selector. Although other than an ability to create one by implementing an interface, i didn't find any information. My implementation is going to have some non-static dependencies, and i need to make sure it makes its way there before its called by unity. Is this possible?

[brittle nebula]

I am trying to use unity netcode, but whever a client joins the rigidbody physics just completelly breaks and he just starts to glitch fly around. I don't even have any code which controls the rigidbody its just the rb itself seamingly broken? It works all fine for the one who hosts it, but for the client it breaks the, also the only thing it has is a collider and rb and a network object component.

[prime sinew]

This seems like a crosspost, please delete this

[gray mural]

just wonder if someone knows it by any chance

[woven dome]

Hi there
Does anyone know the reason why this would both print out false?

Pose left = default;
Pose right = default;
Debug.Log ( left == right );
Debug.Log ( left.Equals( right) );

[cold egret]

- Is pose a struct?

[knotty sun]

because left and right are 2 different objects

[gray mural]

you have to override bool Equals

[woven dome]

yes, so all their values are 0 by default

[woven dome]

they can't be by default

[knotty sun]

but == and .Equals does noty compare contained values unless you program it

[woven dome]

== does in the Unity API

[knotty sun]

thy are 2 instances of the pose object containing default values

[gray mural]

what ?

[woven dome]

yes, so either equals or == should return true

[knotty sun]

because Unity wrote it that way

[gray mural]

they both don't.

you need to compare struct values

by overriding bool Equals

[woven dome]

that's what == does internally

[gray mural]

it doesn't

as you see.

[woven dome]

you can't override internal Unity API operators can you?

[knotty sun]

.Equals and == are c# not Unity

[gray mural]

yes, you can do it for classes and structs I guess

for classes for sure

for struct I guess too

[woven dome]

the implementation is from Unity since it's a Unity steuct

[knotty sun]

now you say that

[gray mural]

@woven dome that's how you override "==" and "!=" of struct

private struct Nice
{
    private int foo;
    private float bar;

    public static bool operator ==(Nice left, Nice right) =>
        left.foo == right.foo && left.bar == right.bar;

    public static bool operator !=(Nice left, Nice right) =>
        !(left == right);
}

[woven dome]

and how do I do it for Unity classes? like Vector3?

[gray mural]

and yeah, that works for struct

I was not sure

[knotty sun]

docs for Pose say == is overriden so (left == right) should be true

[gray mural]

just the same like with class

[gray mural]

you can compare Vectors, what's the problem here?

do it the same like with a struct

private class Nice
{
    private int foo;
    private float bar;

    public static bool operator ==(Nice left, Nice right) =>
        left.foo == right.foo && left.bar == right.bar;

    public static bool operator !=(Nice left, Nice right) =>
        !(left == right);
}

[woven dome]

because the Unity API already does that inside the implementation of == of Pose but it's still returning false

[gray mural]

I don't know whether it has, actually. I have just shown how to override it.

[knotty sun]

you should probable use Pose.identity instead of default

[woven dome]

I don't want to create a subclass, and can't even for structs

[woven dome]

that's a good idea, didn't even know it exists, thanks

[knotty sun]

thats why there are docs

[gray mural]

default should do the same.

it doesn't though

that's strange

@woven dome can you try to convert default to Pose

Pose left = (default)Pose;

idk if that helps

[tropic quartz]

Just for my curiosity I tried declaring just 1 pose, setting it to default, then asking it if "somePose == somePose (yes, the same var twice) and it says "false".

[knotty sun]

i wonder if that is because Pose contains a Quaternion and a default Quaternion is not a valid one

[gray mural]

That's because of null.

If some fields are null - comparing those fields will result in null

[tropic quartz]

Ooh!

[gray mural]

Quaternion.identity does not contain null

[knotty sun]

there cannot be any nulls in Pose

[gray mural]

so it returns true

[gray mural]

hold on, there should be

[knotty sun]

where?

[gray mural]

@tropic quartz you can try debugging it

[knotty sun]

it's 4 Vectors and a Quat

[gray mural]

that's the only explanation.

there should be

[knotty sun]

obviously not

[gray mural]

obviously? do you have other explanations?

[knotty sun]

yes, as I said, default Quaternion is not a valid quaternion

[gray mural]

it's not null, right ??

or it is?

can you debug it?

[knotty sun]

Quat is a struct it can never be null

[gray mural]

Vector3 is not though

no, it is

[knotty sun]

yes it is

[gray mural]

I think

[gray mural]

yes, it is

[knotty sun]

so Pose can never contain any value that is null

[gray mural]

that makes sense and doesn't at the same time

[tropic quartz]

Yeah in case there was confusion I didn't use .identity. That's var is just Pose somePose

[knotty sun]

i agree, logically default Pose == default Pose. The fact it is not means that the == override is checking for something

[gray mural]

.. = default; ??

[tropic quartz]

yeah.

[knotty sun]

so what happens if you use identity?

[gray mural]

it returns true

[knotty sun]

qed

[gray mural]

because everything is 0

[knotty sun]

no everything is not 0. everything is 0 if you use default

[gray mural]

ok, everything but w is 0

[knotty sun]

and a Quat with a 0 w is invalid

[gray mural]

yes, because of this formula

w = sqrt(1 - (x^2 + y^2 + z^2))

w is certain for every xyz

[knotty sun]

indeed, so in the case of Pose it is passing the == check to the == of Vector3 and Quaternion and, probably the Quaternion == is returning false

[tropic quartz]

I was confused about identity but it's actually static so no wonder I couldn't reference it the usual way.

[gray mural]

I don't get you.

[gray mural]

yes, w is calculated by the script

[knotty sun]

we know that w=0 in a Quat is not allowed, what I am saying is if the == operator of Quat is checking for this it could be returning false because it would be an invalid Quat

[tropic quartz]

Anyway putting Pose.identity spits out this:

[gray mural]

oooh, yeah

you have said it already and I haven't thought about it

that's strange that it doesn't throw any errors

[knotty sun]

which would make default Pose false as well

[gray mural]

that makes sense now.

[knotty sun]

easy check
Quaternion q = default;
Debug.Log(q == q);

we know Vector3.zero is perfectly valid so it can only be the Quat causing the confusion

[tropic quartz]

Yeah that q is false in Debug.Log

I tried

[gray mural]

yeah, we know it now

[knotty sun]

#archived-code-general message

[gray mural]

though we should have checked them both

[tropic quartz]

Well as a newbcake, I learned something new, heh.

[gray mural]

I wonder

[gray mural]

that's about programming 🤔

[knotty sun]

tbh, I had not expected this behaviour either but it was the only thing that made sense

[gray mural]

that's because it doesn't throw any errors that we all have got used to

[knotty sun]

well that and I dont make a habit of having invalid Quats in my data

there is a reason why Quaternion and Pose have a .identity static property, it's not just for show

[gray mural]

private static readonly Pose k_Identity = new Pose(Vector3.zero, Quaternion.identity);

Vector3 also does have Vector3.zero

though you can set it as Vector3 vector = default;

so it doesn't make so much sense if I don't miss something

[knotty sun]

so Vector3.zero == default Vector3
but Quaternion.identity != default Quaternion

[gray mural]

yeah, still they have added Vector.zero that is just default Vector3

and we all use it, not default

I guess we all do

[knotty sun]

I guess 99% of Unity users does not even know that default exists

[gray mural]

yeah, C# probably do

[leaden ice]

Sometimes there's readability/code maintainability advantages to defining something like Vector3.zero even if a language feature can technically get you the same thing

[gray mural]

just wanted to say that it's more readable

[knotty sun]

need to be careful with default because of differing behaviour between structs/primitives and classes

better to have an explicit .zero

I'm trying to get my player to move in the same direction of the camera, I have mouse look and player controller

[gray mural]

subtract vectors

[inland crescent]

oh okay thank you so much

[gray mural]

to get the direction from player to camera - you have to

camera.transform.position - player.transform.position

I am sorry if you have understood this from my previous message

just clarifying it

[inland crescent]

got that, just now focusing on how to make the player controller react to the direction its pointing toward

[gray mural]

is it a question?

[inland crescent]

yes sorry my phrasing is bad

[gray mural]

I didn't get that question

can you explain better?

[inland crescent]

heres whats happening

[gray mural]

oh, so you need to add screen rotation functionality?

[leaden ice]

you'd have to show your current movement code, so we can adjust it properly

[inland crescent]

yeah i'd like to see how to implement that correctly, the player controller moves in W,A,S,D and I'l show it now my bad haha

[gray mural]

!code

[gray mural]

where are you even programming?

[leaden ice]

basically before you do controller.Move(move * ...); you have do to move = controller.transform.rotation * move;

to adjust the input for the actual direction it's facing

[inland crescent]

Sorry I'll use the visual studio i was previously using

[leaden ice]

and yeah that looks like either notepad or vim without any line numbers

[gray mural]

are you not going to say anything about their ide?

[inland crescent]

okay thank you

[leaden ice]

nah, since you already said it

[inland crescent]

I'll keep that rule in mind, I'm still newish to the server

[gray mural]

Does anyone know how to clear TMP_Text's last line?

so I have:

dsjfds flkdsjfsfudso fisdufsd iuosnewrnrwejlskdfs
fsdoreuiw rewjls jfdsoufds ijlfw jrewjk rewljk w
ewroufdsjl kfsdjkfdsljk weoriur ewui rewfsdlaj fds
fdsajfdsfdsfsdasfd

I need to have:

dsjfds flkdsjfsfudso fisdufsd iuosnewrnrwejlskdfs
fsdoreuiw rewjls jfdsoufds ijlfw jrewjk rewljk w
ewroufdsjl kfsdjkfdsljk weoriur ewui rewfsdlaj fds
