i feel like they are just kind of slow nowadays and keep getting slower because unity

but you can maybe profile it? i never tried

ultimately it will always take some time though and if there's no reason to spend that time, it seems good not to

[heady iris]

the more stuff there is, the longer it takes

i do need to look into profiling that

It's ultra-fast in an empty project

[hard viper]

does domain reload also have to reset non-serialized fields in SOs?

[wicked scroll]

i don't think it touches SOs

[heady iris]

mmm, that's something I'd need to double check

I know that changes to serialized fields on scriptable objects can appear to persist from play mode session to play mode session

(and then go away after the objects actually unload)

[wicked scroll]

right? i think that's because domain reloads are just for monobehaviors

which is why statics are a problem, because they too get 'missed'

[heady iris]

a domain reload will reset static fields back to their default values

it's creating a new application domain

afaik

time to go check

why does the enemy stay in place? https://gdl.space/xigebuluzu.cpp

yet still tries to move towards me like i want it to

[hard viper]

ok, this isn't quite right

    objBase.customDrawLogic = gameObject.AddComponent(objBase.drawSpecialLogic.Type) as ICustomDrawLogic;
}
Debug.Assert(objBase.customDrawLogic.gameObject == gameObject, $"Cust....```
objBase is an SO. customDrawLogic is a public, non-serialized interface field. That interface contains a singleton. This code (at the last line) says missing reference exception because objBase.customDrawLogic references an object that has been destroyed

I'm literally checking if it is null in the line above

[heady iris]

sweet, exactly what I expected

the Domain Reload reset the non-serialized fields

but Unity persisted changes to the serialized fields

[hard viper]

that is dogshit

I'm just turning back on domain reload

I need to domain reload anyway whenever I change my code

and he most common case is entering playmode exactly once after changing code

I am absolutely not going through every non-serialized field, and micromanaging that

and then depending on having done that right

[dawn apex]

nvm i figured it out

[dusk apex]

So you've checked if it was null above. Assuming it was, you've attempted to add a component to this game object and reference it as an interface (potential null).

[hard viper]

it does implement that interface tho

[heady iris]

the cast can silently fail if something is wrong there

[hard viper]

it works fine on domain reload

[heady iris]

oh, I see it

[dusk apex]

What if the added component isn't of the type?

[heady iris]

customDrawLogic is an interface type

you aren't getting Unity's null comparison logic

[dusk apex]

Relative to cast

[heady iris]

you'd need to cast it to UnityEngine.Object and then check if that's null

the interface type is just going to do a reference equality check

[hard viper]

I used Debug.Log right before my assertion, and it is not null

[heady iris]

and that returns false because it's not literally a null reference

it's just a reference to an object unity happens to think is destroyed

[dusk apex]

Else we're assuming it isn't entering the if statement and actually null but not null

[hard viper]

but it does throw a missing reference exception the moment I call customDrawLogic.gameObject

[heady iris]

this is the issue. you don't need to keep looking :p

[hard viper]

and I checked customDrawLogic == null AND customDrawLogic is null. Both are false

[dusk apex]

Maybe log if the expression evaluated is null or if the if-statement is occurring

Or if the component after cast is null

[heady iris]

without a domain reload, all of these old static references will remain exactly as they were in the last play session

[dusk apex]

I'm assuming the adding of the component is valid

[heady iris]

they will be references to objects that Unity considers destroyed

but they will still be there, regardless, because C# doesn't care what Unity thinks

this is happening specifically because of the interface type. it skips Unity's custom null comparison logic.

If the domain is reloaded before you enter play mode, that field will be a literal null reference

[hard viper]

honestly, I think I will spend less time waiting for domain reloads, then I will debugging to make sure not domain reloading is an accurate match in final build

[heady iris]

it's especially important to disentangle unity objects and C# objects from each other when you're dealing with interface types

[idle rose]

I have this Input Actions Asset.
What I want to achieve is : Change the value of the 'Movement' Action through CODE at runtime

I know you can read values by getting the action, and doing ReadValue

However I want to know how to SETValue (which doesn't exist) to manually override this at runtime

lets Say I want to temporarily control the input through code

how do I do this?

[hard viper]

I would not do that

I would make a singleton with a super high execution order. Have this subscribe to Movement, make whatever edits you need for its own internals, and then all your scripts reference this singleton

eg ProcessedInputManager : Singleton<ProcessedInputManager>

[idle rose]

dang. okay.

Would've been nice to have the option for everything to go through a single action. That way the player can switch between using the premade bindings (WASD) and the virtual controls im making

and it would've been a cleaner implementation i feel

but if its not ideal or doable, I guess I will have to work around it.

[heady iris]

I wonder if https://docs.unity3d.com/Packages/com.unity.inputsystem@1.7/manual/Testing.html could help you out

you wouldn't actually be writing tests, so you'd be able to ignore most of it

you'd be creating a fake device, basically

[lavish frigate]

Hey guys. Currently i have a variable that is true when spacebar is held (using new input system). This works fine for what i have, but now i need this variable to be false after like a 0.x delay. So it should only turn true for a while after a press/hold. Any suggestions or solutions on how to approach this problem?

[lavish frigate]

My issue here is that when the button is held, it is always true as it is subscribed to jump.performed

[heady iris]

The input system alone won't do that for you. Maybe you could write a custom processor?

I would just implement that logic myself.

[lavish frigate]

i guess thats what i gotta do

was hoping for the easy way out haha

[west merlin]

The First Person Controller from the Unity Starter Assets limits the number of decimal places to 3 after calculating speed. Is this an optimization of some kind? FirstPersonController.cs, line 179.

The comments don't offer an explanation, and I haven't found a reference to this as a general technique on Google...

[lean sail]

Most people dont just have the code open/wont go find it to help you. Can you show the lines you're referring to?

[west merlin]

Sure thing: https://pastebin.com/7kaJPELb

[spiral geode]

taking an online tutorial and I ran into a situation where the instructor's implementation smells, however I'm not an expert in unity/C# so I'm assuming there is a reason he went with the implementation that he chose. Here is his top-level scriptable object. He's assigning bools to indicate the "type" of room that it is. This seems bad because:

1. it's not really a type-safe way to assign behavior to something (you're checking a property at run-time instead of type-checking it during compile, when you're validating things)
2. each room type is now aware of the other characteristics of room types outside of itself

[CreateAssetMenu(fileName = "RoomNodeType_", menuName = "Scriptable Objects/Dungeon/Room Node Type")]
public class RoomNodeTypeSO : ScriptableObject
{
    public string roomNodeTypeName;

    #region Header
    [Header("Only flag the RoomNodeTypes that should be visible in the editor")]
    #endregion Header
    public bool displayInNodeGraphEditor = true; // for example, we don't need Entrance in the dropdown - since it's a special case
    #region Header
    [Header("One type should be a corridor")]
    #endregion Header
    public bool isCorridor;
    #region Header
    [Header("One type should be a corridorNS")]
    #endregion Header
    public bool isCorridorNS;
    #region Header
    [Header("One type should be a corridorEW")]
    #endregion Header
    public bool isCorridorEW;
    #region Header
    [Header("One type should be an entrace")]
    #endregion Header
    public bool isEntrance;
    #region Header
    [Header("One type should be a boss room")]
    #endregion Header
    public bool isBossRoom;
    #region Header
    [Header("One type should be None (Unassigned)")]
    #endregion Header
    public bool isNone;
}

Is there any reason that I shouldn't refactor it into something like this:

public class Corridor : RoomNodeTypeSO
{
        roomNodeTypeName = "Corridor";
}

public class CorridorNS : RoomNodeTypeSO
{
        roomNodeTypeName = "CorridorNS";
}

...
...
...

basically, wherever he would validate the room type via some check like isCorrider - I could check that it is type Corridor.

is there some pattern in C# that makes it useful to set this kind of behavior up via these OOP properties/bools?

[lean sail]

It's hard to say what they were thinking, I'm gonna assume it's for consistency sake like for printing the speed to screen. Even the other code is questionable

[heady iris]

this could just be an enum

[lean sail]

Yea enum as Fen wrote, but dear lord those regions are horrible

[heady iris]

using many bools would make sense if a RoomNodeTypeSO could be many types at once

and yes, I have no idea what's up the regions

[spiral geode]

can enums have the stringy-name thing on them?

[heady iris]

they aren't exactly saving space...

[heady iris]

enums are just integers under the hood

but you can get the name of an enum and display that, or write a method that gives you a string name for an enum

[spiral geode]

i mean it seems like he's going to use the roomTypeName string for labels later

i see

[heady iris]

public string GetName(EnumType myEnum) => myEnum switch {
  EnumType.Foo => "Foo",
  EnumType.Bar => "Big Bar"
};

[spiral geode]

not sure about the behavior later, but i think it may need more functionality than enum?

like an algebraic datatype

a "family" of coproducts to a parent type

i just hate the bool thing and I'm not sure if it's going to be important later

[west merlin]

Alright, thank you for taking a look at it

[heady iris]

I would give a room a list of qualities it has

like having an exit in the east, or being a boss room

but that's getting into "how your game is designed" territory

[spiral geode]

what datatype would it be?

classes that inherit from the parent scriptable object?

[swift falcon]

When i shoot into the void, the hitposition becomes 0,0,0. How can i make it so it chooses a point within the path instead of the origin

[heady iris]

I would not create a custom type for every possible kind of room

RoomWithEastExitAndABoss

[lean sail]

Even the lerp in the code is kinda bad, so you're better off finding a new guide/tutorial. That was likely written just to get something working, rather than being a production ready script

[heady iris]

I wouldn't use the type system to make sure I create valid room layouts.

[spiral geode]

why not?

[heady iris]

you could express individual attributes as interfaces, I guess

that sounds incredibly funky

[lean sail]

!code and also you need to check if the ray hit anything. If it didnt, then choose a point along the ray (like 50 units away for example)

[spiral geode]

for instance, a function that's like ConnectingToRoomNode (SomeKindOfCorridor corridor) would tell me at compile-time that i need to be using a corridor

whereas the isCorridor thing allows you to pass any type of room

[swift falcon]

how would i write that?

[spiral geode]

like the SOLID principles

[west merlin]

I have a couple different systems I'll be trying. That was about the feeling I got from the code as well... Good to know it wasn't just me! Thanks again

[lean sail]

You already check if the ray hit anything, just dont use the hit.position if it doesnt hit anything. It is 0 because it didnt hit anything

[heady iris]

if you really can only connect to corridors, then sure, but what if you want to connect to other rooms directly?

now you need to prove that the room can be connected to

[spiral geode]

lol I'm actually not sure yet!

im guessing that's a later lesson

[heady iris]

what if it doesn't have a door that can connect to your room? maybe it's already attached to something else

[swift falcon]

how would i write it to to choose a position along the ray?

[heady iris]

at some point you wind up trying to punt the entire runtime program into the compiler

and that takes you to c++ template hell

[spiral geode]

yeah this is what i like!

[lean sail]

There is a method under Ray which does this for you, look at the docs. I dont remember the name right now

[swift falcon]

oh cool thanks

[soft shard]

A Ray provides a origin and direction, you can use the direction and multiply it by however far you want it to travel, the resulting vector would then be your end point, or the equivalent to a "hit point"

transform.Rotate(Vector3.up * mouseX);

anyone have any idea why camera is snapping so weirdly?

[indigo oyster]

Hi everyone. I try to keep this short. I always loved game dev and decided to try and learn unity with C#. For now only 2 D tho. I heard from someone that there is a tutorial for Flappy Bird, which is about one hour long. I am enjoying the process of following it and Start to understand the basic basics. But I don’t know what I am suppose to do after. Just create a Game and learn what I need when I need it, learn advanced C# or focus on thinks like sprite art and game design while getting code from ChatGPT or so.

[heady iris]

i bet you included Time.deltaTime when calculating mouseX

if you did, that's wrong. remove it and adjust your sensitivity down to compensate

[timid depot]

removed now but still seems to be snapping

[heady iris]

show your whole script

[timid depot]

void UpdateLook()
{
    float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity;
    float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity;

    transform.Rotate(Vector3.up * mouseX);

    float xRotation = cam.transform.localRotation.eulerAngles.x;
    xRotation -= mouseY;
    // clamping
    if (xRotation > 180)
    {
        xRotation -= 360;
    }
    xRotation = Mathf.Clamp(xRotation, -90, 90);

    cam.transform.localRotation = Quaternion.Euler(xRotation, 0, 0);
    GetComponent<Rigidbody>().angularVelocity = Vector3.zero;
}```

I tried adding camera smoothing but still snapping but smoother

[heady iris]

you've got a rigidbody

that's going to be fighting with your attempts to rotate the transform

ah, that's on a different object?

ok, you're rotating transform with the yaw input and cam.transform with the pitch input

Get rid of the rigidbody and observe how it behaves. It should look smooth at that point.

[timid depot]

ok one second

[heady iris]

I haven't made a 3D character with a rigidbody like that before -- always a character controller of some kind

What you could do is rotate the camera to where you should be facing every frame in LateUpdate

[timid depot]

i tried using charactercontroller but it seems to break physics

[heady iris]

especially if you also have a Rigidbody!

[heady iris]

you'll want to track the yaw angle you want to have, instead of using Rotate to spin the transform a little bit each frame

Set the rigidbody to have that rotation in FixedUpdate and make the camera have that rotation in LateUpdate

[timid depot]

okay give me a second

ok I made x axis and for now it looks promising

still behaves weird

maybe it's unity's editor problem and on compiled game it will work correctly?

[heady iris]

Have you checked how it behaves without a rigidbody?

[timid depot]

yes the same

I think its fixed when i put it inside Update instead of FixedUpdate

[heady iris]

Ah. That's why I asked for the whole script :p

Each frame, a certain amount of mouse input is detected

since you were using FixedUpdate, you were only getting whatever input happened to come in the frame before a physics update happened

[timid depot]

sorry for problem and thanks for help

[heady iris]

FixedUpdate is also bad for Down/Up input, since those are only true for a single frame

and you can wind up missing them

[timid depot]

I know but I remember doing some physics tests back in the day

and it was really weird when using Update

[heady iris]

Physics-related things should happen in FixedUpdate, yes

[jagged snow]

If you have a BehaviourTree and a GOAP system for your AI Agent, do you only communicate between BT and GOAP
or do you also communicate with BT and Agent as well?
Goal: Reach Player or Move To Position
but there are other things such as attack which is just one sequence of a task therefore is it worth going through the GOAP class to do this?

[lament cove]

I used those Quaternion (eulerAngles) and Transform (localRotation) methods, until Quaternion.Euler, but they gave the same result (the same as in the screenshot). But even though one believes that it affects the rotation somewhat, it seems that it still moves correctly even if the values are not coincident (I no longer know if those values affect in terms of precision).

[heady iris]

Yes, you'll get a tiny bit of numerical error

[craggy totem]

Hello devs, who knows how to get this Vector3 coordinates , knowing

1. StartPoint(Vector3),
2. Distance from startPoint , and
3. Angle (Vector3)- it is Direction vector.

For example if i write this Raycast, it - will end exactly at point i need.

Physics.Raycast(StartPoint, Angle, out hit, Distance );

but i just need that end point's Vector3

[hidden parrot]

What, get the point where a raycast hits something? its hit.point no?

[craggy totem]

no i dont need to check anything, i dont need collision check. only Vector3

[lean sail]

Cant you just use the hit.position? Also Ray has a method which calculates the position after a distance. It is a simple calculation still of originalPos + (dir * dist)

[somber nacelle]

or if nothing is hit, it's literally just StartPoint + (Angle * Distance)

assuming Angle is normalized since you said it was a direction vector

[craggy totem]

at moment i'm using that "Angle" in Physics.Raycast
so i assume it is normalized

[somber nacelle]

dunno what you mean by that

Hi, i have a problem with my cameras, and it may be something dumb but here it is. I am trying to use a secondary camera to create a reflection of the upper part of my screen in a river, and even when i change the settings of the second camera to be the exact same size as the main one, it isn't. Here are the screenshots

they have the same size/scale parameters but are still different sizes i don't understand why

[cosmic rain]

It kinda looks like they have different positions in the scene view

Oh, they do

I think it's just the difference between screen resolutions.🤔

They seem to be roughly the same size on the y axis. Only different on the x axis.

And your scene view window on the top screenshot seems to be slightly wider than on the bottom.

[west nova]

okay thanks for the tips vOlt i will try it out right now 👍

[umbral chasm]

Can I have a question about how many design pattern does I need for a pokemon type game ?

[cosmic rain]

How many pushups do I need to do to order pizza?

Does that make any sense? Neither does your question.

You use whatever design patterns make sense in your project. The count doesn't really tell anything. And the type of a game is not related to design patterns in any way either.

[spring creek]

0-1 at minimum. 0 will be tough though

[cunning escarp]

Does anyone know how you would script the equivalent of a fixed joint? I know they essentially just add the exact amount of force of the object they are attached to, but idk how the rotation would be done. (I can’t use a fixed joint because I need the object to be able to move both with and independently of the second object at the same time. I found an old thread detailing pretty much my exact problem but with no answers: https://forum.unity.com/threads/script-the-equivalent-of-parenting-for-physics.393490/ . Any help would be appreciated!

[wicked scroll]

maybe https://docs.unity3d.com/Manual/class-PositionConstraint.html and/or some rotation constraints, which let you kind of do 'parenting' without the hierarchy? there's also damped transforms in the rigging package which feels similar to but not quite what you need https://docs.unity3d.com/Packages/com.unity.animation.rigging@1.1/manual/constraints/DampedTransform.html

otherwise yeah you can write a script which will copy whatever pieces of that over you need, it's just figuring out exactly what that means for what you're doing

[west lotus]

I would insert my own custom system that runs after FixedUpdate and just copy over the velocity and angular velocity from one rb to the other. https://docs.unity3d.com/ScriptReference/LowLevel.PlayerLoop.html This repo has helper methods to make things easier https://github.com/Baste-RainGames/PlayerLoopInterface

I'm trying to figure out what refresh rates are supported as I'd like to include the monitor refresh rate as an option when running in fullscreen mode. I wrote some code to get all refresh rates and screen res options as reported by Screen.resolutions.

My confusion is that it is reporting some strange refresh rates that I don't understand where they are coming from.

My code displays the following as refresh rates, but Nvidia / Windows only report 60hz and 120hz as supported by my monitor.

60hz
72hz
75hz
120hz
56hz
70hz

Code I'm using:

    void GetSupportedScreenSettings()
    {
        //Temp lists to add objects to as we collect possible options
        List<int> tempRefreshRates = new List<int>();
        List<Rect> tempScreenRes = new List<Rect>();
        foreach(var res in Screen.resolutions)
        {
            //Use a rect cause whatever, I just want a simple object to store width/height
            tempScreenRes.Add(new Rect(0,0,res.width, res.height));
            tempRefreshRates.Add(res.refreshRate);
        }
        //Move them to a distinct array
        supportedScreenRefreshRate = tempRefreshRates.Distinct().ToArray();
        supportedScreenResolutions = tempScreenRes.Distinct().ToArray();

        string temp = "";
        string temp2 = "";
        foreach(var i in supportedScreenRefreshRate)
        {
            temp += $"{i}hz\n";
        }
        foreach(var i in supportedScreenResolutions)
        {
            temp += $"{i.width}x{i.height}\n";
        }
        Debug.LogError(temp + "\n" + temp2);
    }

Hi, i have a problem with Nav Mesh. If I create more than 1 enemy, they go to the corners and stand there

if you leave the enemy alone then everything is fine

[stark plaza]

What is best for this thing? I have a grid that is manually built (not built on start). Each tile can have some differences. Using InputSystem, If i press wasd or gamecube dpad I can navigate the grid (a grid cursor should appear over the tile). Only with mouse if hover a tile the grid cursor automatically goes there: tile layermask.
I could use IPointer interfaces or else a mouse to screen raycast but I don't know how I would get the specific tile since all are adjacent
Sometimes I struggle to find the better approaches
actually most of the time

Hey so architectural question here. I have a series of items that the player can collect. Once collected, the item shouldn't appear again. How should I go about tracking this?

    private void Follow()
    {
        if (speed <= 23)
            speed = Mathf.Lerp(speed, RR.KpH / 5, Time.deltaTime);
        else
            speed = 23;


        gameObject.transform.position = Vector3.Lerp(transform.position, child.transform.position, Time.deltaTime * speed);
        gameObject.transform.LookAt(cameralookAt.gameObject.transform.position);
    }

    private void boostFOV()
    {
        if (Input.GetKey(KeyCode.LeftShift))
        {
            UnityEngine.Camera.main.fieldOfView = Mathf.Lerp(UnityEngine.Camera.main.fieldOfView, desiredFOV, Time.deltaTime * smoothTime);
        }
        else
            UnityEngine.Camera.main.fieldOfView = Mathf.Lerp(UnityEngine.Camera.main.fieldOfView, defaultFOV, Time.deltaTime* smoothTime);
    }
}

I want to know why the camera follows the car for the first second but then it slows down continously to the point where it doesnt move

[knotty sun]

because you're using the current FOV in your Lerp

Hi, I am having this weird problem.
I use the AssetDatabase class witch it linked the package for. But it keeps unlinking and every time I connect it again by clicking the option given in the error message it's fine for some time (from 10s - 2min) and then does it again.
Do you know what might cause this? I am using it in the Start() method.

[heady iris]

AssetDatabase is a UnityEditor class.

You can't use it in the built game.

What are you trying to achieve here?

(that's not necessarily what's causing the error message here; it's just important :p )

[subtle jungle]

I have a basic movement and a basic camera script on my unity project i've notice this problem where the camera is "jittery" it is very noticeable if you look around an object
heres my camera script:

    public float sensitivity;

    public Transform playerCam;
    private float xRot;
    private Vector2 playerMouseMovement;


    void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }

    void Update()
    {
        playerMouseMovement = new Vector2(Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y"));
        xRot -= playerMouseMovement.y * sensitivity;
        transform.Rotate(0f, playerMouseMovement.x * sensitivity, 0f);
        playerCam.transform.localRotation = Quaternion.Euler(xRot, 0f, 0f);
        xRot = Mathf.Clamp(xRot, -90f, 90f);
    }

[earnest nebula]

I am trying to get a path of a file which is part of the script
I assign the file from directory where it's saved
the file contains string which I'll be saving to an Array
I could put the path in manually but I want to use it for more files later and writing path manually just seams weird

[heady iris]

I was about to say "don't use deltaTime!"...but you aren't! good

How is the player being moved?

[heady iris]

These files won't exist in the built game.

all of your Assets get bundled into a few big archive files

What are you trying to accomplish here?

not "get the path of a file"

[earnest nebula]

sorry, I don't think I quite follow

[swift falcon]

Hey could anyone help me create a good script for movement wasd on unity i have no clue what im writing and need help really bad

[subtle jungle]

rigidbody i can send the code if you want

[heady iris]

What are you doing with these files? Why do you think you need file paths?

[lavish pine]

for some reason the player is unable to move forward even though its detecting the fact that the player is pressing the W key . i am using ;netcode for gameobjects; for the networking

[heady iris]

is the camera parented to the object with the rigidbody?

the rigidbdy will, by default, only move during physics updates

this will result in a lot of jitter

[earnest nebula]

open the file
store the content of the file into Array
and then use and modify the Array

[subtle jungle]

yup

[heady iris]

If you just need to read a text file, then you can directly reference a TextAsset

that's the kind of asset you get when you drag a .txt into your project

[subtle jungle]

ok i will try updating the camera's transform to an empty gameobject while keeping the player outside/unparented to the player

[heady iris]

turning on interpolation on the rigidbody could help

I'm not sure what the "correct" fix is here, though. I've never really done rigidbody-based first person games

[lavish pine]

ok the code seems to work now

[heady iris]

AssetDatabase doesn't exist at all in the built game, and the files in your Assets folder will also not exist in the built game.

[earnest nebula]

oh okey
sry I haven't realised that it comes with this kind of method
thank you so much for your help

[earnest nebula]

okay, I think I get it now
thank you

[subtle jungle]

i already have the rigidbody set to interpolation

[subtle jungle]

ok so i tried doing that but now i cant look on the x axis

its only on the y axis

[heady iris]

In that case, make sure that you are not modifying the transform of the rigidbody at all

it'll overwrite whatever you do

[lavish pine]

how do you make it so that the forward velocity is capped after it reaches a certain value ?

[latent latch]

compare and set?

[knotty sun]

Clamp it

[lavish pine]

also is there anyway to check if the forward velocity reaches a certain value ?

[knotty sun]

if ?

[lavish pine]

oh wait does velicity use local or global posititions ?

[dusk apex]

neither

[knotty sun]

what? Velocity is not positions

[lavish pine]

sorry for the confusion . i am applying a relative force on the Z axis and what i want to do is to see if that forward velocity is more than my max speed and if it is cap it to that value

hopefully this makes what i am trying to do a bit clearer

[knotty sun]

so check if velocity.z is greater than max speed and if so clamp it to max speed

[lavish pine]

so it would look like this right ?

[knotty sun]

no

[swift falcon]

hey how can i make crouch code for my movement code

[simple egret]

Velocity will be represented in world space, use transform.InverseTransformDirection(rb.velocity) to convert it to local space

Or multiply the velocity with your transform.rotation, that should do the same normally

[lavish pine]

so it would look like this ?

[lean sail]

Look at the docs for Clamp, what you wrote doesnt make sense.
Also I believe force isnt added right away, so you might want to clamp the velocity regardless if they press W. Or you might run into cases where people can move faster than your max speed because they let go of W and it didnt clamp properly after the last add force

[lavish pine]

allright . thanks for the help

[sacred sinew]

I need to access the data from tiles but it say to me there is an error, I don't understand what is the error

[knotty sun]

why would you think that the TileData struct contains a property tiles?
https://docs.unity3d.com/ScriptReference/Tilemaps.TileData.html

[sacred sinew]

it's in a scriptable object

[knotty sun]

and?

[simple egret]

Side-step, avoid using var when the type on the other side is not clearly apparent

This makes the code harder to read

Show the definition of TileData, because seeing how it's colored, it's a class, meaning it's not Unity's TileData struct

[sacred sinew]

yep it's a script

[simple egret]

Okay so tiles is in fact just one tile

So you can't foreach through it

[latent latch]

one whole tile

[simple egret]

Rename to tile for clarity

[hard viper]

let's say I have an Action<>, and I want to subscribe a method to it as Method(fixedInput). I want to also be able to both += and -=, and I worry doing
+= () => Method(fixedInput);
will make that not work because it is anonymous

suggestions for how to do this the most cleanly?

I could define a private method, but just wondering if that is the only way

[knotty sun]

also, if you must duplicate Unity class/struct names at least have the sense to put them in your own namespace

[lean sail]

Youd have to store the delegate or write it in a method to be able to unsubscribe. Unless you want to unsubscribe by assigning the whole action to null

[simple egret]

You can store the lambda in a field, then (un)subscribe to/from the field

[hard viper]

I have a system like this which is a lot smarter

[simple egret]

Good. Now you don't need the inner foreach loop, add tileData.tile to your Dictionary

[sacred sinew]

ok thanks

[timid depot]

where can I ask about meshcollider?

[hard viper]

tiles is not an IEnumerable

in my equivalent of a tiledata class, I have a method that outputs a List<TileBase> to get all tiles for that tileData.

this way I can have a TileData that corresponds to multiple tiles

I have a child class of it, which does have multiple tiles
TileAssembly : TileData

also, don't do public float etc in your SOs. you want to protect that shit like a dragon protects their hoard of gold

the standard pattern is:
[field: SerializeField] public float myValue {get; private set;}

if you make it fully public, you allow other scripts to not just read, but to EDIT your SO, which would be catastrophic for this sort of system

[hard viper]

do you understand?

[sacred sinew]

yes i do

[hard viper]

one thing I wish I did was make that dictionary a private dictionary, with public property IReadOnlyDictionary

private Dictionary<....> myDict;
public IReadOnlyDictionary<....> MyDict => myDict;

this makes the dictionary publicly readable, but nothing is allowed to modify it outside the class

because I use this dictionary literally everywhere in my game

[dawn canopy]

Hey all,

I have an object with AudioSource and a controller script (UIAudio) attached to it, and I want to play different sound effects. But now that I want to play coin sfx, it still plays the main click sfx, even if I manually change the clip to coin sfx from unity inspector.

public class UIAudio : MonoBehaviour
{
    [SerializeField]
    private AudioSource audioSource;

    [SerializeField]
    private AudioClip clickAudioClip;
    [SerializeField]
    private AudioClip coinAudioClip;

    private bool shouldDestroy = false;

    private void FixedUpdate()
    {
        if (!audioSource.isPlaying && shouldDestroy) Destroy(gameObject);
    }

    public void Play(bool shouldDestroy)
    {
        audioSource.Stop();
        audioSource.clip = clickAudioClip;
        audioSource.Play();
        // I believe below is to continue playing the sound effect in the next scene, and then delete the object.
        this.shouldDestroy = shouldDestroy;
        DontDestroyOnLoad(gameObject);
    }

    public void PlayCoin()
    {
        audioSource.Stop();
        audioSource.clip = coinAudioClip;
        audioSource.Play();
    }
}

uIAudio.PlayCoin();

[rigid island]

which method

how do you call playcoin

[dawn canopy]

Is it important? I believe it definitely gets called, as I logged it and it also plays the other sound effect. (click clip)

[rigid island]

its kind of important if you want to debug it

[dawn canopy]

public void WatchAd()
    {
        //uIAudio.Play(false);

        if (IsLoading()) return;
        BeginLoading();

        RequestAd();

#if UNITY_EDITOR
        EndLoading();
        EarnNClose();
#endif
    }

    private void EarnNClose()
    {
        uIAudio.PlayCoin();
        coinManager.ReceiveMoney(14);
        ClosePanel();
    }

[dawn canopy]

here. WatchAd() method is part of another gameObject and gets called by a UI Button

[rigid island]

and these two run for sure ?
EndLoading();
EarnNClose();

[dawn canopy]

Yeah, I just put a Debug.Log in PlayCoin itself to make sure it gets called

[rigid island]

oh ok hmmmm . that DDOL is kinda weird but shouldn't cause issue if you already start with correct assigned sfx

[hard viper]

can someone explain why my IDE is putting this global:: thing on some class I'm modifying? eg buildingCreator = global::BuildingCreatorEditor.GetInstance();

I have never written global:: myself. So I want to know what made this exist

[fervent furnace]

change the language mode to c#? but it looks like hybrid of cpp and other languages

[simple egret]

It refers to the global namespace

[rigid island]

This is used to specify the global namespace

[hard viper]

I understand. but I did not type it, so my IDE put it in there.

in a different file that I was not editting

[simple egret]

Like if you had your own System namespace inside another namespace, then to access Microsoft's System namespace, you'd need to do global::System

[rigid island]

print something more useful in the log, like check which sound clip is assigned perhaps before playing?

[fervent furnace]

just googled c# allows such syntax...

[hard viper]

my IDE is definitely set to C#

I suspect I accidentally tried to rename a class

but I'm still confused

[simple egret]

Yeah sometimes it does that with the Quick Actions. The snippets it inserts contains the most declarative code possible to avoid ambiguities, then simplifies it as much as possible until an ambiguity is found, or until it can't simplify anymore

Like the for code snippet, will insert a for (global::System.Int32 i = 0; ..., and simplify it down to for (int i = 0; ...

[hard viper]

ok but can you explain what I personally did to prompt this modification in a file that was not open

[simple egret]

Any Quick Action that would modify other files

[dawn canopy]

Updating my method to:

public void PlayCoin()
    {
        audioSource.Stop();
        Debug.Log("1 " + audioSource.clip);
        audioSource.clip = coinAudioClip;
        Debug.Log("2 " + audioSource.clip);
        audioSource.Play();
        Debug.Log("3 " + audioSource.clip);
    }

log:

1 mixkit-handgun-click-1660 (UnityEngine.AudioClip)
2 mixkit-coin-win-notification-1992 (UnityEngine.AudioClip)
3 mixkit-coin-win-notification-1992 (UnityEngine.AudioClip)

But in the inspector, it still shows handgun:

[simple egret]

Renaming with Ctrl+R², adding a new member, modifying a method signature...

[hard viper]

i suspect i did the rename

so would you say: 1) putting class into namespace, 2) ctrl + R rename. That this prompts global::NewName

[dusk apex]

Well, you've assigned it to the coin audio after the first print.. so it'll print the coin audio for the latter two.

If you're referring to the property, maybe check to ensure you're looking at the correct object.

[dawn canopy]

Yeah, but it doesn't play it, it instead plays "click" audio clip

[dusk apex]

Add the second argument cs Debug.Log(..., audioSource);

[simple egret]

I'd say the latter. If I were to do the renaming utility, the operation would be done in 3 steps:

1. Expansion. The class name and all its references are prefixed with its explicit namespace structure class Sample -> class global::Sample
2. Rename. The references to it are resolved and renamed.
3. Simplification. The name is removed because there's no ambiguities class global::Sample -> class Sample

[dusk apex]

Afterwards, click the log and see which object becomes highlighted.

[dawn canopy]

I did add the second argument, but nothing changed in my log

[rigid island]

its meant to click the log and check which object is calling the log

indeed there might be a clone?

[dusk apex]

Add a Debug.Break() after play.

[rigid island]

there is a DDOL in Play, maybe that has something to do wit it

[dawn canopy]

It the same object that I was inspecting before

[dusk apex]

Also, show an image of the console logs

[swift falcon]

Hello guys, I am following code Monkey's tutorial ( this https://www.youtube.com/watch?v=AmGSEH7QcDg&t=405s ) , and I have a problem I have been trying to find a solution for 1 hours now lol, I would love some insight / hints from experienced people, Am I allowed to ask my question here ?

[dusk apex]

Can you show the entire console window?

[dusk apex]

Ensuring that it doesn't get played then stopped immediately

[dawn canopy]

Again, it does get played, but it playes another clip, the "click" clip instead of the "coin" clip

[dusk apex]

With the debug break, what does the inspector show for the object?

[dawn canopy]

I added debug break:

public void PlayCoin()
    {
        audioSource.Stop();
        Debug.Log("1 " + audioSource.clip, audioSource);
        audioSource.clip = coinAudioClip;
        audioSource.Stop();
        Debug.Log("2 " + audioSource.clip, audioSource);
        audioSource.Play();
        Debug.Log("3 " + audioSource.clip, audioSource);
        Debug.Break();
    }

And the inspector still shows the wrong clip, and the wrong clip gets played

[swift falcon]

i got Animation set up but it changes idle animation instant to walking animation and doesnt stop how to fix?

[dusk apex]

https://docs.unity3d.com/ScriptReference/AudioSource-clip.html

Maybe yield a frame

[dawn canopy]

Didn't work

public IEnumerable PlayCoin()
    {
        audioSource.Stop();
        //Debug.Log("1 " + audioSource.clip, audioSource);
        audioSource.clip = coinAudioClip;
        //yield return new WaitForEndOfFrameUnit();
        yield return new WaitForFixedUpdate();
        audioSource.Stop();
        //Debug.Log("2 " + audioSource.clip, audioSource);
        //Debug.Break();
        audioSource.Play();
        //Debug.Log("3 " + audioSource.clip, audioSource);
    }

[simple egret]

Or use PlayOneShot()

If you need multiple sounds at once, one set in the Audio Source, and another that should be played from code, then you should be using two distinct sources

[dusk apex]

Define worked? I'm assuming no sound played at all...

[dawn canopy]

It plays the other sound effect, not that one that I'm setting

[dawn canopy]

It sill plays the other sound effect

[simple egret]

Yes because OneShot overlays the sounds

[dawn canopy]

What if a game has like 15 sound effects per scene, there should be 15 game objects with 15 audio sources?

[dusk apex]

Use the debug break and see what clip is assigned to the audio clip - assuming all prior images were not during runtime

[simple egret]

No, one source with multiple clips fed in OneShot

With play scheduling made in the code, if you don't want them to overlap

[dawn canopy]

This is during runtime, and with Debug.Break, before and after Play

[dusk apex]

Not sure what's going on. Simply changing clips seems to be an issue that you're having overall.

The playing of the correct clip will be resolved if you can determine why swapping clips isn't possible

[dawn canopy]

Now I'm using OneShot everywhere, still the same result

    public void Play(bool shouldDestroy)
    {
        //audioSource.Stop();
        //audioSource.clip = clickAudioClip;
        //audioSource.Play();
        audioSource.Stop();
        audioSource.PlayOneShot(clickAudioClip);
        // I believe below is to continue playing the sound effect in the next scene, and then delete the object.
        this.shouldDestroy = shouldDestroy;
        DontDestroyOnLoad(gameObject);
    }

    public void PlayCoin()
    {
        //audioSource.Stop();
        //Debug.Log("1 " + audioSource.clip, audioSource);
        //audioSource.clip = coinAudioClip;
        //yield return new WaitForEndOfFrameUnit();
        //yield return new WaitForFixedUpdate();
        //audioSource.Stop();
        //Debug.Log("2 " + audioSource.clip, audioSource);
        //Debug.Break();
        //audioSource.Play();
        //Debug.Log("3 " + audioSource.clip, audioSource);

        audioSource.Stop();
        audioSource.PlayOneShot(coinAudioClip);
    }

I'm guessing that you're stopping and reassigning the clip to gun

[dawn canopy]

removing stop here, made it work properly

Although I'm not sure why
But the problem seems to be solved

Thank you for your time@dusk apex @simple egret @rigid island

[rigid island]

nice glad you got it working

what an odd thing, even though I just use PlayOneShot mostly

[heady iris]

which Stop did you remove?

[swift falcon]

https://gdl.space/jadexabaza.cpp I can't get the aim down sight to work. When i shoot, the camera doesn't stay fixed onto the sight, which is the aimpoint. adsPosition is the position of the gun when aiming.

whats wrong it only does idling animation and doesnt switch to walking when pressing w

[willow meteor]

Hey guys, I have an issue currently with TwoBoneIKConstraints.
In editor everything works fine, but whenever I build the game and the Weight is set to anything else than 0, the game crashes. It worked perfectly for about 3 months and it started happening when I implemented a save system with PlayerPrefs (which do no modify anything related to TwoBoneIKConstraint). Any help to debug / fix this issue would be greatly appreciated.

[heady iris]

this is literally trying to set a bool named "IsWalkingHash"

i presume you meant to use IsWalkingHash

[dusk apex]

Both statements require your animation state to be is walking.

Assuming is walking is false, neither will run and you'd stay idle

[simple egret]

Yeahh that's a lot of code to do a simple thing, this can be simplified down to anim.SetBool(IsWalkingHash, Input.GetKey("w"))

That single line

[swift falcon]

oh

where do i put it

[simple egret]

Also as your IDE suggests (three dots below Input), prefer using the enum for the key, instead of a string. KeyCode.W

[heady iris]

stop and think about what this line of code does

If you don't understand, ask

[swift falcon]

im clueless about these lines i only know movement ones these sound really wierd to me

[heady iris]

https://docs.unity3d.com/ScriptReference/Animator.SetBool.html

then read the documentation.

[swift falcon]

i dont this ones right either

okay i got it to do walking animation but it doesnt do idle animation or stop doing animation when pressing w

[simple egret]

That would be an Animator setup issue because, ignoring the simplifications this code could use, it's correct

[swift falcon]

i changed get getkeys to getkeydown and getkeyup

[latent latch]

in the animator you'd have your idle state (usually the entry point) where if you've conditions for when you're not in any current state to fallback into it

[swift falcon]

i have it like this

[latent latch]

it's a little confusing because you still have to mimic a lot of the state logic script-side, so your script does end up looking similar to how the animator blend tree would look like. The benefit of this though is it's easier to trigger one-off animations and jump rightback into the previous animation.

[rocky jackal]

my unity overlap sphere has a dead zone for some reason, if another object is too close to the center it stops working and doesnt detect the object anymore

[latent latch]

click the arrows in between and make sure the transitional logic is correct

[swift falcon]

i have left arrow on IsMoving false and left arrow is IsMoving true

[dawn canopy]

All of them

public void Play(bool shouldDestroy)
    {
        audioSource.PlayOneShot(clickAudioClip);
        // I believe below is to continue playing the sound effect in the next scene, and then delete the object.
        this.shouldDestroy = shouldDestroy;
        DontDestroyOnLoad(gameObject);
    }

    public void PlayCoin()
    {
        audioSource.PlayOneShot(coinAudioClip);
    }

[latent latch]

if you keep the animator tree open side by side as you can see the routes it tries to take. Without knowing more I can only guess that the idle clip isn't set, or there could be an exit lag problem on the blending timeline

[swift falcon]

yea it skips idle and goes straight to walking and then cant find back to idle

now it shows this

[hard viper]

hello! im trying to create a game with cars and i want to add to the main menu some kind of way to select cars and preview them in 3d something like this: https://youtu.be/wjwf4AKfNF4?si=FIa4lyfOhvwowfOm&t=133

does anyone know how could i do this

or have a tutorial which i could watch

[rigid island]

you give me idea for a video xD thx

anyway its not diffcult to make at all

they pretty much explain it in the video

they just use a scrollView component for the sliding UI

the cars are rendered with RenderTexture which is a special texture that can be outputted to from the camera/gpu

[solemn shale]

Would like some feedback on whether this is a decent strategy. So I'm continuing my quest to implement saving and loading. I have a number of modular systems that presently handle their own saving and loading internally. However, this creates many save files, and it'd probably be better to store them all in a single save file per run. That naturally would require coupling.

However ...

I am considering using interfaces and injection. So you have an ISaveable interface that has Save, Load, and Clear methods. Each System inherits from this. Then each system has a corresponding save interface that the central repository inherits from: IGlobalSettingsData, IPlayerPositionData, IInventoryData, etc. The specific interface gets injected.

public class SaveObject : IGlobalSettings, IPlayerPositionData, IInventoryData, ...

{
  public IGlobalSettings ...
  // Local properties gotten from and sent to the SaveObject

public void Save(){
    // Assign each property to IGlobalSettings
  }

  public void Load(){
    // Get each property from IGlobalSettings
  }
}```

However ...

Interfaces can't store fields and, from my understanding, you can't serialize properties to something like JSON.  So I would have to convert to a backer field inside the SaveObject class.  I am aware that C# allows you to do this:

```[field: SerializeField] public int MyField { get; private set; }```

However, if I go to serialize MyField into a JSON string, will that work or do I need to explicitly make a local serializable field for it?

[rigid island]

just use Json.net (It can write properties just fine)

JsonUtility is hot trash

[spiral geode]

@heady iris you were right yesterday about using an Enum

not sure if you remember

but representing "flavors" of something via instances of a thing - and the collection of those things being a List<Thing> just adds so much unecessary complexity

enum solves basically all of those problems

[simple egret]

And for putting it all in the same file, I suggest doing it by compressing the contents into a ZIP archive with the stuff in the System.IO.Compression namespace. If you haven't got any solution in place already, of course

[heady iris]

you can also make the enum values into powers of two so that you can use it like a bitmask

very handy if you need multiple-choice

I think there is a lot of merit to using more complex datatypes, but only when you actually need more expressiveness

[spiral geode]

this is all that isCorridor stuff I was mentioning yesterday (I still think the instructors bool implementation is the worst version)

[knotty sun]

you're right, it is terrible design

[spiral geode]

i ended up making them all types like Corridor, and doing the matching via thing is Corridor for the logic

[spiral geode]

the bool stuff?

yeah

[knotty sun]

yep

[spiral geode]

my hesitency for Enum was just because I wasn't sure if he had a good reason that he would reveal later on

spoiler: he didn't

another problem with my "typed" solution is that Unity gets annoyed when you orphan classes in one big file

it really urges you to break them out into files named after the class

so that was kind of a waste of time

and even if there is special logic associated with each Enum member - I can solve that with a static function from Enum -> Whatever

[heady iris]

You can move from an enum to a more elaborate type if necessary, after all

(maybe scriptable object assets)

[spiral geode]

yeah this is all SOs

[heady iris]

I'm making pretty heavy use of those in my current game

it's nice to be able to just serialize a localized string on something instead of having to look up a translation at runtime with a hardcoded string

[spiral geode]

i think the course is still worthwhile, since I'm learning some unity tools I wasn't aware existed (like creating a new editor window that does custom stuff)

[heady iris]

editor windows are fun

[spiral geode]

this is like a level-editor tool he's making

[heady iris]

you will get exposed to a lot of "unity plumbing" as you get into editor tooling

stuff that you're normally not exposed to, like serialized objects and serialized properties

[spiral geode]

yeah like the whole EditorGUI.BeginChangeCheck() stuff is neat

[knotty sun]

forget all that old crap, if you're doing Editor tooling today you should be using UIToolkit, it's far superior

[heady iris]

I really gotta learn UIToolkit

I've used it a little for making custom property drawers, but not for anything substantial.

[spiral geode]

i didn't even know there is a new one

he's using the old input system too

[knotty sun]

if you've ever done any web dev (HTML/CSS/JS) it's a doddle

[heady iris]

EditorGUI/etc. is "immediate mode" GUI

you draw it every single frame

this is simpler to reason about than "retained mode" GUIs, where you just set it up once and then reference the things you created

but you also have to draw the entire GUI every frame.

[spiral geode]

googling UIToolkit

[heady iris]

it also results in some rather confusing code

OnGUI gets called multiple times, IIRC

since Unity has to first figure out how much space things will take up, then paint them

UIToolkit is basically HTML flexboxes.

[spiral geode]

and runtime UI for games and applications.
people using this for in-game menu?

[heady iris]

(Unity UI is also basically flexboxes)

[rigid island]

You could never do this with JsonUtility 😏

public class Saving : MonoBehaviour
{
    private void Awake()
    {
        var data = new SavingData()
        {
            ImAProperty = "Hello From Property :)",
        };
        data.ImADictionary.Add("Hello", "Hello From Dictionary");
        var jsonData = JsonConvert.SerializeObject(data);
        File.WriteAllText(Path.Combine(Application.persistentDataPath + "/File.json"), jsonData);
    }
}
public class SavingData
{
    public string ImAProperty { get; set; }
    public Dictionary<string, string> ImADictionary { get; set; } = new();
}```
Definitely switch over to Newtonsoft if you plan on doing real saving system

[knotty sun]

one of the things I love about UIToolkit is it's so easy to make and consume your own widgets, makes life so much easier

[heady iris]

• IMGUI: immediate-mode; anything using GUI / EditorGUI / etc for both games and editors
• Unity UI: retained-mode; RectTransforms and LayoutGroups for games
• UIToolkit: retained-mode; VisualElements for both games and editors

[spiral geode]

looks like the official unity youtube video is using it in the context of an in-game menu (so it can do editor stuff and game stuff)

[rigid island]

UIToolkit is awesome, confusing a bit at first but def puts IMGUI to sleep

[spiral geode]

i guess i'm using IMGUI in this course

[heady iris]

having actual automatic layout is nice

I've gotten a very good handle on Unity UI, so now I've got that sunk cost going

[spiral geode]

i bet that ebook on the unity resources page (the one about making an advanced UI) is using this

[rigid island]

the binding handling is so much more straight-forward, also very intuitive if you come from XAML

[spiral geode]

their youtube example looks like the same assets

[knotty sun]

I've done a shed load of IMGUI in the past, tbh I'm glad to see the back of it

[spiral geode]

that ebook you linked @rigid island is great BTW. been reading it daily

[rigid island]

I still use traditional UI because im used to it but im making all my custom editor in uitoolkit

[rigid island]

glad it helped out! they have tons of those

[spiral geode]

they have a pretty nice blogpost on the ui stuff

https://blog.unity.com/engine-platform/new-ui-toolkit-demos-for-programmers-artists

[rigid island]

so glad they also added the UI Toolkit editor so you can visual build it

[rain minnow]

That's what I'm doing right now. I really like how it's set up. I just have to find a preference: utilize the editor, or code the ui with uss . . .

[rigid island]

Same 😅 I tried doing it all in C# without UXML and it came out to be kind of a pain and giant class to mantain, dont mind UXML since it gives that feel of XAML so I feel familiar having done most of my work in the new windows UI / Maui

How would i go about getting and preserving the player's local y velocity, i am making a game where you can walk on a planet (player is a child of the planet), currently the movement works fine but when i walk to the side of the planet the physics start to act weird (eg. player starts to fall diagonally, player jumps diagonally from the pov of the player), i want to preserve the player's y velocity but somehow in local space? how do i do this?

movement method:

Vector3 moveDir = new Vector3(Input.GetAxisRaw("Horizontal"), 0, Input.GetAxisRaw("Vertical")).normalized;
Vector3 targetMoveAmount = moveDir * walkSpeed;
moveAmount = Vector3.Lerp(moveAmount, targetMoveAmount, Time.deltaTime * 8);

private void Movement()
    {
        float currentYVelocity = rb.velocity.y;

        Vector3 newVelocity = orientation.TransformDirection(moveAmount);

        newVelocity.y = currentYVelocity;

        rb.velocity = newVelocity;

        Debug.DrawRay(transform.position, newVelocity);
    }

Preserving player's local y velocity correctly

[solemn shale]

When you say add it by name, does that imply I can't access it through the Package Manager window?

[knotty sun]

no, that is an option within the package manager

[solemn shale]

Is it this one? Cuz I don't see any other options for JSON, .Net, or Newtonsoft.

Hey, I'm working on a deck builder game where there's a deck for the entire run and it gets cloned for a battle. For some reason, it seems like if a card is modified during a battle, it is also permanently changed, but it shouldn't. Look at the code below where I've put the methods that are called in order, what am I missing?

// DECK CONTROLLER
        public DeckController Clone() {
            List<CardInfo> deckCardClones = new List<CardInfo>();

            // Moved to TryAddCardToDeck.
            foreach (var card in _deck) {
                deckCardClones.Add(card.Clone(CreatedBy.DECK_CLONE));
            }

            return new DeckController(deckCardClones, _skipShuffle);
        }


// THE CARD
        public CardInfo Clone(CreatedBy createdBy = CreatedBy.UNKNOWN_CLONE) {
            if (createdBy == CreatedBy.DECK_CLONE) return new CardInfo(this, createdBy);

            var cI = GenerateCardInfo(_cardData, _owner, createdBy);
            cI.SetCreatedBy(createdBy);

            return cI;
        }

        public CardInfo(CardInfo cardInfo, CreatedBy createdBy = CreatedBy.UNKNOWN) {
            _owner = cardInfo._owner;
            _createdBy = createdBy;
            _isUpgraded = cardInfo.IsUpgraded();
            
            AssignVariables(
                cardInfo.GetCardDataForArt(),
                cardInfo.GetCardId(),
                cardInfo.GetCardName(),
                cardInfo.GetManaValue(),
                cardInfo.GetShuffleTypeValue(),
                cardInfo.GetSpeedValue(),
                cardInfo.GetElement(),
                cardInfo.GetKeywords(),
                cardInfo.GetCardDataForArt().tetheredCard
            );
            
            InitializeEffectControllers();
        }

[rain minnow]

Yes, the file can quickly build up when creating the UI in C#. It helps to use the builder pattern with extension methods to quicken the process

I use the UI builder myself. The layout is so much easier than before. Once I figure out accessing the binding properties to alter/ update the design based on field values, I'll be good . . .

[rigid island]

Did you find it, if not look at what Fen sent

[rigid island]

Yeah Im glad they added UI Builder, it makes everything much easier if you can see it visually .Very good tool

good tip on the builder pattern, I should've just done that 😅

[SerializeField] private LocalizedString m_PasswordErrorText;

How do I get the string from this ?

PopupManager.MyInstance.AddToQueque(m_PasswordErrorText.TableEntryReference);

Does not work ? AddToQueQue is a string

[rigid island]

what exactly "doesn't work"

[heady iris]

TableEntryReference is not the localized string

It's a key used to look something up in a string table

m_PasswordErrorText.GetLocalizedString() will work

Hey I am trying to make a random scrolling animation that selects a item (like what it looks like when choosing a mini game in Mario party) does anyone know how to make it or better yet a tutorial.

oh that looks even easier lol

literally just scrolling through a simple list and adding the visual highlight for the indexes

break down the issue into smaller steps, I don't think you would find such a specific video.

pick the random item is the easy part ofc, the hard part is smoothing the UI to look just right

[autumn gorge]

Oh wait that sparked something I might know how to make it thank you

[solemn shale]

Yes, I did. Thank you.

Now I just have to figure out how to use it. 🙄

[rigid island]

did you click "Documentation" ?

also my example shows, its literally 1 method

https://www.newtonsoft.com/json/help/html/SerializingJSON.htm

you're basically just swapping JsonUtility static function with this class instead

[solemn shale]

So as simple as just replace this line?

TO: string json = JsonConvert.SerializeObject(saveObject);```

[rigid island]

yes exactly

i have a Game Manager type script that i send events and names and IDs and such to. There is a significant amount of boiler plate code involved in doing this, every time. Is there a set of built in functions i am not aware of that does things like ('object a-script a), get info variable somename from (object b-script b)'?

[chilly surge]

What does your current code look like?

[twilit scaffold]

private void Start()
    {
        // Find the GameObject with the "Player" tag
        GameObject playerFarmer = GameObject.FindGameObjectWithTag("Player");

        if (playerFarmer != null)
        {
            // Access the GameObjectInfo component and call ReturnName
            GameObjectInfo gameObjectInfo = playerFarmer.GetComponent<GameObjectInfo>();

            if (gameObjectInfo != null)
            {

                string playerName = gameObjectInfo.ReturnName();

                // Use the playerName as needed in the Odin script
                Debug.Log("Player Name: " + playerName);

        else
        {
            Debug.LogError("Player-Farmer GameObject with 'Player' tag not found.");
        }
    }

[rigid island]

create extention classes/methods

[twilit scaffold]

I was thinking that, that was probably the way.. now i have to figure out exactly how 😅

[chilly surge]

Beyond architectural changes, some basic syntax changes will make this a lot more palatable:

• Have a method GetComponentOnGameObjectWithTag<T>(string tag) so you are not repeating the same finding and checking code over and over.
• In the implementation, make use of guard clauses.

Hello, does anyone know which are the JoystickButton numberd for the arrows on the left of a PS4 Joystick?

[twilit scaffold]

Thanks., I will start attempting to implement that now

[twilit scaffold]

Ok, i think i got it. still finalizing testing

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

public class GOUtility : MonoBehaviour
{
    public static T GetComponentOnGameObjectWithTag<T>(string tag) where T : Component
    {
        GameObject[] gameObjectsWithTag = GameObject.FindGameObjectsWithTag(tag);

        foreach (GameObject go in gameObjectsWithTag)
        {
            T component = go.GetComponent<T>();
            if (component != null)
            {
                return component;
            }
        }

        return null;
    }

}

[chilly surge]

GOUtility does not have to be a MonoBehaviour unless it has specific reasons to, otherwise it can just be a plain C# class. Make it static too if it's not meant to be instantiated.

[twilit scaffold]

Thanks., i will have to go a bit further to determine whether it will eventually require MonoBehaviour or not. Changing to static now. Edit: Oh, ok, making it static insists on removing MonoBehaviour

Is there an equivalent to Rigidbody.AddForceAtPosition for rotational velocity? One that would change both velocity and angular velocity as one would expect when trying to rotate an object away from the center of mass? I see Rigidbody.AddTorque, but unless I am mistaken, that only changes angular velocity. Is there maybe a way to calculate the force and torque manually? Also, is anyone having issues where docs.unity3d.com is just not loading? The docs for Rigidbody.AddForceAtPosition is still showing the loading icon, and the page for Rigibody isn't loading at all.

Ah, yeah, that is a different subject entirely, but good to have in the links

[granite crown]

I don't see in this code where you are comparing to another button, just the button color itself.

[twilit scaffold]

ended up doing this

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

public static class GOUtility
{
    public static T GetThisComponentFromGameObjectsWithThisTag<T>(string tag) where T : Component
    {
        GameObject[] gameObjectsWithTag = GameObject.FindGameObjectsWithTag(tag);

        foreach (GameObject go in gameObjectsWithTag)
        {
            T component = go.GetComponent<T>();
            if (component != null)
            {
                return component;
            }
        }

        return null;
    }

}

which allows me to get the variables of the dynamically instantiated game objects with the much shorter method of :

    string playerName;

    private void Start()
    {
        GameObjectInfo playerGameObjectInfo = GOUtility.GetThisComponentFromGameObjectsWithThisTag<GameObjectInfo>("Player");
        if (playerGameObjectInfo != null)
        {
            playerName = playerGameObjectInfo.ReturnName();
            Debug.Log($"Player name is {playerName}");
        }
    }

pretty new to programming, so the verbose names help me think it through

[jade vault]

I'm also new, whats the benefit to this, when you can just do

GameObject.FindGameObjectWithTag("Player").GetComponent<GameObjectInfo>().doSomething();

other than it being ugly 😆

this is also coming from the guy whos inventory script controls building as well

[teal parrot]

It looks like his searches through all with the tag to find one with the component, where as that would break if it first found an object with the tag but without the component.

[jade vault]

Ah, yeah makes sense to condense searching all gameobjects with tag player then checking their components in its own method*

[teal parrot]

Though I do recomment using .TryGetComponent<T>() and using the boolean output rather than comparing with null.

There's probably some Linq shenanigans that could make that in one line if you were really deticated.

Maybe this?

GameObject.FindGameObjectsWithTag(tag).Select(x => x.GetComponent<Rigidbody>()).FirstOrDefault(x => x != null);

[jade vault]

I have a question my building system checks for collision and if it collides with an object (the player moves the mouse and it casts a ray) I have a bunch of conditionals to check what object it hit.

Heres a really condensed version

if (hit.collider != null && hit.collider.gameObject.transform.parent != null)
{
  if (hit.collider.gameObject.transform.parent.gameObject.CompareTag("Carpet"))
  {
    if (activeItem.name.Contains("Carpet") || activeItem.name.Contains("Floor") || activeItem.isWalkable)
    {
      return;
    }
  }
}
...

(checks parent object as objects can have a physical item pickup collider)
What can I do to make this less convoluted?

in this specific condition, if the player holds an item that is a carpet, floor, or its walkable, it will return making it so it cannot be placed

[teal parrot]

@jade vault
Physics.Raycast returns true if it hits something, which can replace hit.collider != null.
I believe you could do hit.collider.gameobject.transform.parent?.gameobject.CompareTag("Carpet") to avoid checking if the parent is null, the question mark tells it to evaluate to false if it gets null there.

[jade vault]

Ah, thank you. I am using Physics2D, does that change things?

I'm sure they are identical in some ways.

[twilit scaffold]

hmm. probably not much (beyond the null checks). i am just new enough to have to stick with the first thing that makes sense for a while, until the 'other' thing starts to makes sense 🙂

[chilly surge]

It also does not handle null, if for example the player game object is not found, it would proceed to throw NRE.

[teal parrot]

Yes, slightly. The function won't return a boolean, but RaycastHit2D is truthy if it hits something, so you can just do if (hit)

[chilly surge]

And you also cannot fix that with ?. because Unity.

[teal parrot]

Aw, unity shenanigans :\

[jade vault]

Dang, I could just make it so instead of checking objects that would cause it to return, check if it the hit is a placeable area and return everything else

[teal parrot]

What exactly is wrong with it? Does Unity's version of c# not support it? Does .parent return some weird value instead of null?

[jade vault]

My building script is 1,600 lines like 400 lines for sure is just conditional statements checking if an object is there

[twilit scaffold]

I simply do not understand that well enough to use it yet 🙂. soon, perhaps

[quartz folio]

https://unity.huh.how/unity-null

[chilly surge]

Presumably in this case using ?. is safe, because I would think FindGameObjectsWithTag and friends would not return GOs that are already dead.

But that would mean you need to suppress analyzer warnings and what not, so yeah I would not recommend.

[quartz folio]

You would use referenceequals if you cared about real null

[chilly surge]

Or is null.

[jade vault]

real null?

[chilly surge]

C# pattern matching is great 😄

[quartz folio]

https://unity.huh.how/unity-null

[jade vault]

Like if an object truly doesnt exist?

Ah I see

[quartz folio]

The array ones will just return an empty array, but anything that doesn't may return Unity null for more context

Not a destroyed object, but a fake one that specifies the origin of the call

[jade vault]

Managed objects will refer to an object as null while the the native compilation would keep a reference to the object

[quartz folio]

It's the opposite

The managed object exists but will evaluate to null via the overridden equality

[jade vault]

Oh

[chilly surge]

Interesting, well it's pretty much to the point you have to know the implementation details of those methods to use ?. safely, so I guess the verdict is "just don't."

[jade vault]

So does garbage collection cause the high-load times with Instantiation as it takes CPU time? Or is it loading that object what causes it to lag.

[teal parrot]

I think garbage collection is asynchronous.

[jade vault]

In a simple 2D sprite renderer object in this case

[quartz folio]

There is nothing collected when you instantiate. The cost is loading the object and allocating memory

[jade vault]

Ah, implemented Object Pooling into my game to remove frame drops when building. Still get frame drops.

[terse quarry]

Why on earth would it think that the 3rd Log is not contained within the other 2?

[teal parrot]

What?

[terse quarry]

The white dots are TL and BR

I declared a rect covering this area

and when I click inside it, it calls the function that SHOULD be called when i click OUTSIDE of it

the third log is the mouse position

first is top left, second is bottom right

the mouse position is in range of the other two

so why does it think its outside the rect

[teal parrot]

Does this new Rect(SimBoundsTL, SimBoundsSize); do anything? Is it creating an object and doing nothing with it?

[terse quarry]

Well thats the region I want to detect clicks inside

I check for that here

[teal parrot]

Does .Contains do what you think it does?

[terse quarry]

I'd hope so lol

[teal parrot]

I'm not sure exactly what SimBounds holds, but .Contains() usually determines if an item is in an array/list/generator

[terse quarry]

Rect.Contains just checks whether a vector lays within the Rect

[spring creek]

What happens in Bag.Update()
Seems like that is the issue, not instantiation?
Also looks like you could have drilled down further in the hierarchy view? Kinda hard to watch it on my phone haha

[teal parrot]

That looks correct then. Are you sure you are creating the rect correctly?

[jade vault]

@spring creek Yeah I could have sorry about that. In Bag.Update it runs the function to check if an object can be placed and then instantiates that object. It also will then update the items in the bag and then updating the slots. When the slots get updated it does instantiate new slots. However, those are also pooled.

[terse quarry]

it says its declared with Rect(x,y,width,height)

and thats what i've done

This is such a stupid thing to be stuck on for hours I have no clue what the problem is

[fervent furnace]

this is GUI space, while you are using it in world space

[terse quarry]

I've tried it in both honestly

[teal parrot]

In your code, I see you create a new Rect, but you don't actually assign it to anything.
variable = new Rect(...) creates a rect and assigns it to variable.
new Rect(...) just creates one and doesn't actually put it anywhere, so it might as well not exist.

[teal parrot]

Did you mean to write SimBounds = new Rect(SimBoudnsTL, SimBoundsSize);?

[terse quarry]

wtf

u are so right

my god

i declared it at the top

but never gave it a value

[jade vault]

@spring creek ah, a new deep profile has discovered the issue. Must have been an editor glitch, it was displaying Instantiate instead of the actual issue. Its my AStar pathfinding updating the region where AI (animals) can walk.

        foreach (GameObject go in gameObjectsWithTag)
        {
            T component;
            if (go.TryGetComponent(out component))
            {
                return component;
            }
        }

        return null;
    }
}

[spring creek]

Ok nice. That does make more sense. It wasn't instantiating that many things quickly

[teal parrot]

If you want to make it even fancier, you can define it in the same line as you call the function.
You can write out T component and by giving it a type, it will create the variable in the same line.

[jade vault]

Thanks @spring creek

[twilit scaffold]

Really!? I did not know that. Ok, trying

Nope., i will have to save that one for later, as i do not understand the syntax well enough. I will keep it in mind though 🙂

wait, did you mean like this?

        foreach (GameObject go in gameObjectsWithTag)
        {
            if (go.TryGetComponent<T>(out var component))
            {
                return component;
            }
        }

[teal parrot]

Yes. var implitly converts to the type of what is being assigned, so it's basically the same as writing T. If T wasn't working, it might be some weird edge case related to generics.

[quartz folio]

you can remove the <T> and replace var with T too

[twilit scaffold]

that was my first try, and for some reason, it did not seem to like it, so i ended up with this syntax. I will try again though, as there is a good chance it was my own user error

Hah. as expected, user error. Seems to be working that way now 🙂

public static class GOUtility
{
    public static T GetThisComponentFromGameObjectsWithThisTag<T>(string tag) where T : Component
    {
        GameObject[] gameObjectsWithTag = GameObject.FindGameObjectsWithTag(tag);

        foreach (GameObject go in gameObjectsWithTag)
        {
            if (go.TryGetComponent(out T component))
            {
                return component;
            }
        }

        return null;
    }
}

That really does make a lot more sense than a null check. Thanks again @ Burrito, Frog Detector, vertx and all

[spring creek]

Can I suggest the name GetCompontOnObjectsWithTag
Just a thought. It aligns more with the two methods your combining

[twilit scaffold]

good idea, thanks. I just had it named that way to cement my understanding of the concept 🙂

public static T GetComponentOnObjectsWithTag<T>(string tag) where T : Component

[spring creek]

Totally fair. Doesn't really matter either way, just popped in my head so I shared it haha

[twilit scaffold]

updated now, because you were correct. makes more sense matching the rest of the names 🙂

[chilly surge]

Try pattern vs get then null check are pretty much just two different ways of writing the same thing, except one critical difference: try pattern allows you to represent success state but with a null result value.

In this case that is not really utilized, so either is fine.

Personally I find try pattern to be a bit icky because of the inline variable declaration, so you have to read to the end of the line to see it.

[twilit scaffold]

For some reason, i was under the impression that is was more efficient, in the long run, than != null. that was just my impression, i am not suggesting that as fact. i surely do not know

[scenic crown]

Was taken away for a moment, yes I am comapring the color of the button

[small ember]

why is this guy using this line of code:

instead of using this?
transform.Translate(Vector3.forward * flySpeed * Time.deltaTime);

not sure if I wrote the code correctly but you get the point

what even is +=?

[outer otter]

if i make a prefab of an object with a collider and trigger on it, how come it doesnt work the same as the original? My code opens a menu when close to an object after a key press. The copy does not

[west lotus]

x+=1 is just shorthand for x= x+1

If you look at what Translate does its the same https://github.com/Unity-Technologies/UnityCsReference/blob/7c95a72366b5ed9b6d9e804de8b5e869c962f5a9/Runtime/Transform/ScriptBindings/Transform.bindings.cs#L147

[west lotus]

Well do you get any errors? Also show the relevant pieces of code. A prefab should work the same as the original

[small ember]

so Translate is the same as x+

+=*

[west lotus]

Translate is a mathematical term that means to move a point in space

[outer otter]

i found out why, I have an object from the desk script that if I used a list instead of a single object it would open up on any desk

[west lotus]

You move a point in space by adding to its coordinates

[lucid parrot]

Am I allowed to ask custom editor related questions here?

[latent latch]

#↕️┃editor-extensions

[lucid parrot]

alr

[leaden ice]

No, since Translate operates in local space of the object by default

[sacred sinew]

I have a hidden tilemap but when I click on the IsActive button, it stay hidden. Do somebody know why ?

[drowsy gazelle]

How is the tilemap hidden? Just with IsActive turned off or is the tilemap renderer disabled?

[sacred sinew]

Is active is off

[hard estuary]

Then probably some other script is turning it off. You can try putting the object in some empty scene without other scripts to see if it behaves the same. If it behaves differently, then you'll know that something is messing with it.

[sacred sinew]

ok thx

[dense tusk]

hello my fellas. i'm working to create a mechanic where an enemy will try to hide from the player when looked at. currently i'm just trying to figure out how to check if the player can see the object. my research has suggested i use raycasts, but that doesn't feel like the right thing to use. i'd like to check if it shows up on screen, not just if the player is looking directly at it. any guidance would be greatly appreciated

[lean sail]

You could check if the renderer is visible (it's a built in field) or possibly use this
https://docs.unity3d.com/ScriptReference/Camera.WorldToViewportPoint.html
Although the last one might have slight edge cases where you can see a part of the object but not the center which you'll have to handle how you want that to function.

[lean sail]

You will need to raycast at some point though, especially if you're trying to have it hide. Otherwise you dont really have a way of checking what areas are visible. Also with the last method I linked, you'll need to raycast so the ai doesnt think its visible but its on the opposite side of the wall

[main coral]

What is the best way to change "ErrorMessages" ?

try { await UnityServices.InitializeAsync(); await AuthenticationService.Instance.SignUpWithUsernamePasswordAsync(m_RegisterUsernameInputField.text, m_RegisterPasswordInputField[0].text); Debug.Log("SignUp is successful."); } catch (AuthenticationException ex) { Debug.LogException(ex); } catch (RequestFailedException ex) { // Compare error code to CommonErrorCodes // Notify the player with the proper error message Debug.LogException(ex); }

[simple egret]

What? The exceptions you get cannot be modified, so you will have to make your own depending on the error code, as the comment suggests

[main coral]

How do I catch i have tried it with string .. if (errorCode == "INVALID_PASSWORD") .. but this does not work

[thin aurora]

This really depends on the exceptions. If it does not have an error code or anything like that you can't do this

[simple egret]

The code will be inside ex so see what's inside that first

[thin aurora]

So if AuthenticationException can specify what went wrong, you can check for that.

Or maybe it falls under another exception type. Consider reading the documentation of what it can throw, perhaps

[simple egret]

And the RequestFailedException will most likely have the HTTP status code in it.

Like 500 Internal Server Error, 404 Not Found, etc.

[main coral]

Yes but how can i catch it in a if statement ?

[simple egret]

You look at the documentation to see where in RequestFailedException it is

[main coral]

catch (AuthenticationException ex) { if (ex.ErrorCode.ToString ==) } catch (RequestFailedException ex) { // Compare error code to CommonErrorCodes // Notify the player with the proper error message Debug.LogException(ex); }

This is the errorcode:

[Authentication]: Request completed with error: {"detail":"Password does not match requirements. Insert at least 1 uppercase, 1 lowercase, 1 digit and 1 symbol. With minimum 8 characters and a maximum of 30","details":[],"status":400,"title":"INVALID_PASSWORD"}

[simple egret]

status: 400
Your exception variable ex should have a Status property, as well as a Title property. You need to check those in your if statement

if (ex.Title == "INVALID_PASSWORD") for example

[main coral]

ex.Title does not exist

That was my question how I get the title or something to change it

[simple egret]

Then use the completion list to see what's available

It's probably under another name

[main coral]

string errorCode = ex.ErrorCode.ToString(); if (errorCode.Contains("INVALID_PASSWORD")) { Debug.Log("TEST ERFOLGREICH"); }

This does not work but the error:
[Authentication]: Request completed with error: {"detail":"Password does not match requirements. Insert at least 1 uppercase, 1 lowercase, 1 digit and 1 symbol. With minimum 8 characters and a maximum of 30","details":[],"status":400,"title":"INVALID_PASSWORD"}

[simple egret]

Just look at the documentation it will be much faster

[main coral]

Where do I find it ?

[simple egret]

On the internet

[severe sable]

is this a bug with unity?

My script very clearly inherits monobehavoir and is in the right namespace

my IDE sees no issue and I tried restarting unity & discarding VCS changes and rebooting also

it just won't recoginize this file for some reason

[mellow sigil]

Did you try without the namespace

I don't think it's a good idea to use Unity's namespaces in your own scripts

[severe sable]

I can definetly try, its weird though since other scripts are using the same namespace in the folder and work totally fine

apparently that fixed it? so am I just not able to use the namepsace scenemanagement without conflict?

its odd I never got a warning from unity before or smth

also even weirder is it worked yesterday

and only one file broke

[hard estuary]

Sometimes such issues can be fixed by reimporting corrupted file. Bugs happen.

[dawn apex]

Can anyone help me with detecting if my character has rotated 360 degrees within a certain time frame?

to then trigger an ability

[latent latch]

https://docs.unity3d.com/ScriptReference/Vector3.Angle.html

[dawn apex]

ok ill check that out

[latent latch]

Well, some requirements I'd set is a counter that accumulates degrees rotated over the time frame. Not sure how you'd want to handle if a character rotates an opposite direction such as reseting the counter entirely.

Or just decrement the degrees

[dawn apex]

ok thx

ok so im sorry but i have 0 clue as to how i would implement that with this gameplay. (The ability should trigger once the mouse has rotated around the player)

[severe sable]

huh, that worked, thank you so much for that little trick! I'm definetly going to get a lot of use out of that

[latent latch]

float degreesDif = Vector3.Angle(previousForward, currentForward); //or w/e forward is in 2D
float totalDegrees += degreesDif;

few things though is you need to also figure out if you're rotating in the same direction

[dawn apex]

alright

[latent latch]

such that if you rotate clockwise then add positive degrees, otherwise negative degrees

and both values of 360 and -360 should work

[dawn apex]

alright man i appreciate you so much, but i think im to stupid too do this and ive been on this for 2 hours. I give up sorry

[latent latch]

lol well, you were almost there

[dawn apex]

well i dont know how i would implement half of the stuff you were talking about

[latent latch]

just finding the angle between two vectors

[dawn apex]

yup, no idea

[latent latch]

and adding em up

[dawn apex]

yup

thanks tho

[pure garden]

any idea if you can differentiate between left and right click with an event trigger from code?

[rigid island]

if you want to use code then just use the IPointer interface and check the click there

[pure garden]

wait nvm

i found it out

apparently you can send pointer event data with event triggers

[rigid island]

yup the code is easier public void OnPointerClick(PointerEventData pointerEventData)

its right in the signature

[pure garden]

yh i found it out late lol

ty anyways

[swift falcon]

can anyone tell me why this code freezes unity (lastX =999 and currentX = 0 by default, something has to do with the while)

[fathom tapir]

What happens if you call LoadAsset() on an asset bundle multiple times?

bundle.LoadAsset<GameObject>(assetName);

Does it create multiple copies in memory or is only one copy ever loaded?

[small ember]

Can someone explain to me how the inside of the "if" line of code works? I don't understand why we are using a new Vector3 and not Vector3 by its self? and why did he write transform.position.y and transform.position.z instead of just writting 0, 0

[dusk apex]

If they wrote zero for y and z, they would be overwriting the previous y and z values. They only want to set the x value to negative ten if the x value is ever less than negative ten.

[humble void]

You can not write directly to one axis of a transform position, so a workaround is to set the other axis to their current value (leaving them untouched) and giving a value to the axis you want to modify

[swift falcon]

can anyone help me pls im in a hurry. ty

[fathom tapir]

You have an infinite loop, which is why its freezing.

[swift falcon]

yea but why

[small ember]

what's another example where you use transform.position.y and transform.position.z

[fathom tapir]

probably need while(condition1 && (condition 2 || condition 3))

try the parentheses

[swift falcon]

lemme try

[fathom tapir]

I'm just guessing that is the logic flow you are attempting

[swift falcon]

like this?

[fathom tapir]

Yes

This would be if contion1 is true and (condition 2 or condition 3 are true)

[swift falcon]

doesnt freeze but doesnt work as intended, thank you

imma rework it

[fathom tapir]

You're welcome. Good luck on getting your logic check correct

[dusk apex]

Last x is not 999 and any value of current x minus last x results in a value greater than 2 - for instance, you would get an infinite loop if last x was negative ten.

Or if last x was 9

[split merlin]

yo can someone help add my idle animation to my character in unity
not the x bot the character that I imported

[dusk apex]

Don't cross post #💻┃code-beginner message

[split merlin]

ok

[swift falcon]

used a way more efficient approach that worked :)

[wraith mauve]

I have a quick question about using Animator Override Controllers (haven't really used them before), but I have a character who can wield many guns, the number of animations on the character (Run, Walk, Shoot etc.) won't change, but the animation clips for each gun will.
Do I create an Animator for, say, 'Character_Base_Anims', then create an override for each weapon and swap out the animator override when I equip a different weapon? Or is the correct workflow to have 1 animator override, and swap out all of the overridden clips based on the weapon equipped?

[vagrant blade]

One override and swap out the clips

The whole idea is to only create a single animator with all the states that you swap the animations used for each state, via the override controller.

[elfin tree]

hey, not quite sure where to ask about this but has anyone used strand based hair simulation?
https://github.com/Unity-Technologies/com.unity.demoteam.hair

I managed to setup everything following the tutorial and it works but for some reason i cannot get a material to be applied to the hair, it always just forms a big color block somewhere and the hairs disappear, no part of the guide talks about materials so i assume just assigning one should make it work?

Hi, I imported the UnityEngines.Splines package through the package manager, but I can't use any of its types inside my scripts, can't even import its namespaces with using directives... I can however, use its components inside the editor. Anyone experienced this before and has some tips? Many thanks!

[rigid island]

wdym you can't use it in the scripts?

try Regen Project Files maybe

[hard viper]

is there a specific size at which Hashset.Contains is faster than Array.Contains?

I assume so?

[west lotus]

[hard viper]

oh god. more benchmarking -.-

[latent latch]

hashset is 0(1)

[fervent furnace]

Hashset.Contains should be always faster than array.contains unless you only have two elements.....

[meager stirrup]

.net runtime can't find the assembly... I'll try regen...

[hard viper]

it's mostly an issue of overhead

I found some benchmarking

[rigid island]

regen also are you using assembly defintions ?

[meager stirrup]

I do have one for the project, but not for the imports

[hard viper]

array is still faster at the 10 element mark

[latent latch]

gotta pay the c# fee

[hard viper]

yeah. array, as always, if best for small numbers

[fervent furnace]

probably cache hit
is the type value or reference?

[hard viper]

benchmarked on int

cost is probably on the get hash value

[hard viper]

btw, Unity source code shows this:

        1 => (Object)(object)other == (Object)(object)this, 
        2 => (Object)(object)other != (Object)(object)this, 
        _ => true, 
    };```

[lean sail]

what are you trying to do

[pure garden]

an item use system which takes a string and returns an ability from a script in resources

the most flexible way possible ^^

(i don't want to make a scriptable object for every ability)

[lean sail]

This doesnt look flexible, looks more fragile than anything. That function is for getting assets. What is CustomClass and how will this provide you with getting an ability?

Scriptable objects seem like exactly what you want here instead

[pure garden]

[System.Serializable]
public class CustomClass
{
    public virtual void Activate() { }
}

public class Base_Use : CustomClass
{
    public override void Activate()
    {
        Debug.Log("use");
    }
}

public class Base_Use_2 : CustomClass
{
    public override void Activate()
    {
        Debug.Log("use 2");
    }
}

if i do

CustomClass use = new Base_Use_2();
use.Activate()

it returns "use 2" as expected

the problem is that i cannot asign customclass from an scriptable object in the inspector

also base_use and base_use_2 are separate files

[crimson plaza]

What's considered the best practices when handling user inputs? Should I use scripts to handle movement via Input.GetKeydown or should I use the build in Input Manager? OR is it just preference

[wide dock]

Well, you kinda can

[pure garden]

any idea on how

[wide dock]

via [SerializeReference]

[pure garden]

doesn't seem to work

[rigid island]

up to you , doesnt matter much.
Look into new Input System though if you want something more modern

[wide dock]

But you need to assign an instance via code

With this approach

[pure garden]

wym

an object with the script?

[wide dock]

[SerializeReference] BaseClass obj = new DerivedClass(); // Or other methods

[lean sail]

If you want it to take in a string, then you're gonna have to declare your own mapping from string to new ClassName.
Aside from that part, you could easily just do this all via scriptable objects, and just put the Activate functionality on a scriptable object

[crimson plaza]

Thanks! On the other hand, I wanted to ask about first and third pesron follow cameras, from my exp with tutorials they typically do it with scripts, and I was wondering if there was a "best practice" floating around

[pure garden]

its literally the same that i had at the start

like the "new DerivedClass()" thing

[lean sail]

Everything is gonna have to be code in some way. Whether you make it or someone else. Use cinemachine, does all the work for you

[wide dock]

Why not do it this way then?

[pure garden]

because you cannot asign it from the inspector of serializable objects

i might just do an scriptable object for every script and thats it

[wide dock]

You can assign it from the inspector, you just have to play around a bit

[pure garden]

before that imma look into this

[crimson plaza]

Is there a downside to using cinemachine

[rigid island]

its too easy

jk

[crimson plaza]

I'm not opposed to writing code (I actually love doing it) but just was wondering, figured I'd ask

[rigid island]

cinemachin will take care of the heavy lifiting (lerping and all that)

you dont need follow scripts for example

[crimson plaza]

So if I were to use my own scripts I'd be writing to simulate what cinemachine does to a degree right

[rigid island]

you plop a target and it follows

[rigid island]

no point in reinventing the wheel

[crimson plaza]

Mhm

[rigid island]

you still need basic stuff esp for FPV
like rotating the eye view with code etc.

[lean sail]

Not really, you just need to learn what to use from all its settings. Theres a lot of options

[lean sail]

What I said is just make SO for the functionality, I'm not really sure where the whole string part comes into play. The string part you should remove, unless the user is typing in words to cast an ability.

[crimson plaza]

Thanks guys

Off to learn cinemachine I go

[fiery oyster]

I have a strange problem, game does only work in editor, doesnt work when built, it looks like from debugging that the Camera Manager would never call the SetupPlayerVirtualCamera() I can go voice chat if that would help

private void Start()

[main coral]

Why is my text on the last line not centered ? What did I make wrong ?

[latent latch]

So I'm rotating around a circle using RotateAround along with MoveTowards to create a spiral effect. I was doing it via rotation + forward velocity but it eventually creates some rotational drift over time. Anyway, assuming my rotating object starts at the very ends of the circle, I want this object to move towards the center pivot at a speed dependent on a duration (normalized time), so it would be distance from pivot / duration.

Now, that works, but let's assume my circle is irregular like an ellipse. Since the radius can differ for where ever it spawns, how would I create a speed that respects where it is on the ellipse, such that it would slow down as it got closer to the pivot, but faster the further away it is.

like I need to normalize speed based on a MAX distance?

oh, wait maybe I just recalculate the speed instead of caching it

right, that's what I get for trying to save those extra few operations

[hard estuary]

Settings seem fine to me. I would check if you have some extra invisible characters between 2nd and 3rd lines. Similar issues can happen when you copy text from text editors. Try deleting everything between 1-st character of the 3rd line and the last character of the 2nd line (including those characters), then retype the missing characters.

[main coral]

OK did work.

Is it possible to add there some information per script ?

Thats the Unity Player Management Dashbord

[rigid island]

no

its extremely limited in info rn

[simple egret]

There won't be any wait between the color changes, that's not how coroutines work

"co-routine" - runs "concurrently", as in parallel to the current code

[heady iris]

StartCoroutine just tells Unity to check on your coroutine method every frame (by default)

When Wait(5f) runs, the Wait method will execute until it hits a yield statement.

It will then return an IEnumerator, which is passed to StartCoroutine. That tells Unity you have a new coroutine for it to keep track of.

This will not stop ChiliRedeem from executing. If it did, your game would freeze.

[simple egret]

You need to make this whole method a coroutine, and yield directly in it.
Or, put the second color change inside the coroutine, after the yield

[heady iris]

Unity will wait for 5 seconds, then ask the IEnumerator returned by Wait for a new value. The method will exit, so the enumerator will report that it's exhausted. Unity will then decide the coroutine is finished (having done nothing)

Also, this will not do any kind of smooth fading of the colors

It's just going to set the color to something between assignColor and Color.white based on the value of timer

https://docs.unity3d.com/Manual/Coroutines.html

read about coroutines here.

I'm wondering how I would detect these voxels that aren't connected to the rest of the group so I can make them fall down

[left violet]

I am just a beginner here would be interesting how to solve this.

Maybe it fits good here now void Start() { InvokeRepeating("SpawnObstacle", _startDelay, _repeatRate); _playerControllerScript = GameObject.Find("Player").GetComponent<PlayerController>(); } if I start a coroutine like this on a SpawnObject for example it will only give me the ability to set the repeat rate once on start right? What ways are there to keep it more open and be able to change the repeatRate for example if I want to make it spawn faster when difficulty gets higher per kill or whatever

sorry not Coroutine but a invokeRepeating

So it would be better to make a CoRoutine and just update the values of the spawnRepeat in the Update method

right?

[clever lagoon]

interesting one! I'd probably start with the ones connected to the ground, and "mark" them with a "1". Then mark each voxel they connect to with a 2- then go through those "2-marked" voxels and do the same marking thier neighbors with a 3, until I reach a loop where every voxel I'm testing HAS a marked neighbor. Finally, those without ANY "marks" fall down. This is very brute force, obviously, and I've got a feeling, not the most optimized approach.

[clever lagoon]

yes, update would work well for this. You COULD also, choose to make your corotine run an infinitite loop- checking the time, and yielding if the timer has not run out..

[latent latch]

really the only neighbors you need to check are those at the top of the brush

[hard viper]

first, don’t call methods by strings. That is really error prone, and usually slow. The usual workaround would be nameof(SpawnObstacle). But you’ll usually want to actually find a different way to just call the method.

[hard viper]

this sounds like you want to use Update()

private float spawnPeriod;

void SetSpawnRate(float spawnRate) => spawnPeriod = 1/spawnRate;

void Update() {
  if (Time.time >= nextSpawnTime) {
    SpawnObstacle();
    nextSpawnTime += spawnPeriod;
  }
}```

[heady iris]

a method you run as a coroutine can still see fields from its class; just store the repeat rate there

[SerializeField] float delayTime;

IEnumerator DoSomething() {
  while (true) {
    yield return new WaitForSeconds(delayTime);
  }
}

[hard viper]

that is an alternate method

my method requires more maintainance, but gives more control over pausing and changing numbers in the middle.

[clever lagoon]

only KINDA coding Q: I wrote a class, but I hate the name- any suggestions for a more descriptive name? /// <summary> /// Represents a scrollable list of unlimited objects, and displays them using a limited/minimal number of instantiated UI Objects. /// </summary> /// <typeparam name="TListElementType">The type of elements in the full list.</typeparam> /// <typeparam name="TLineElementPreFabType">The type of prefab used to display list elements. /// Must implement the <see cref="IDisplay{TListElementType}"/> interface and must be a Monobehavior, to ensure proper functionality.</typeparam> public class LimitedObjectScrollListBase<TListElementType,TLineElementPreFabType>:MonoBehaviour where TLineElementPreFabType : MonoBehaviour,IDisplay<TListElementType> let me know if more details wold help.

[hard viper]

ScrollingCollectionBase

collections by definition contain objects, and have different constraints over capacity

[dusk apex]

ObjectScrollConstraint

[clever lagoon]

good ones! was hoping to highlight the fact that a limited number of UI elements (just enough to fit on screen +2) will be instantiated, regardless of number of items in the list. should I not worry bout that?

[hard viper]

that is just one behaviour of it

not worth putting in the class name

what is it? a collection for a scrollbar

but as an abstract base

oh, it isn’t abstract?

then nvm, don’t put Base in the name

[clever lagoon]

abstract cuz you cannot use generic mono's

[hard viper]

i believe you can AddComponent a concrete mono of generic class, iirc

i might be mistaken. but i think that’s how it goes

in my case, I do keep all my generic monobehaviours abstract, to force inheriting into a concrete

i just noticed a lack of abstract in your signature

[clever lagoon]

I've been creating concrete descendants and adding em into the canvas, at editor-time.

[hard viper]

then add abstract to the declaration

right now you can instance it, and AddComponent during runtime

[clever lagoon]

like this guy public class LimitedFileScrollList : LimitedObjectScrollListBase<FileSystemInfoWithNameOverride, DisplayFileButton> { } and public class LimitedTextScrollList : LimitedObjectScrollListBase<string, TextDisplay> {}

[hard viper]

i know. i do that too

[clever lagoon]

good idea

[hard viper]

in my case, I have

public abstract FixedSpawnPointBase<T> : FixedSpawnPointBase {…}

public FixedSpawnPointSingle : FixedSpawnPointBase<TilePlacement> {…}

public FixedSpawnPointLine : FixedSpawnPointBase<TilePlacementContig> {…} 

public FixedSpawnPointTilemap : FixedSpawnPointBase<TilePlacementContig> {…} ```

[clever lagoon]

it's just a component that creates the line element instances for you. You just have to call public void SetList(List<TListElementType> fullList) and it does the instantiating for ya.

So I need to use a text file to save variables from a script that I modify during play mode so I can set them back in editor mode(theres hundreds of gameobjects with this script, so I cant just use playerprefs or something)
Is there a way to get some ID or something of the gameobject that contains the script whos variables I modified that I can use to find that gameobject again once I back out of play mode?

[hard viper]

for reference, I have a non-generic base class underneath so I can GetComponent etc without knowing the generic form

without unboxing a fuckload of structs

I do recommend consider a similar structure

[clever lagoon]

not sure if this guy will help when you need to go back, in the editor, and find em. but GO's DO have this member: https://docs.unity3d.com/ScriptReference/Object.GetInstanceID.html

[hard viper]

right now, you’d probably need an interface to try to access everything independent of the generic. Such as clicking on element X. An abstract nongeneric class might help a bit

[zinc parrot]

yeah I thought so, but I dont think theres a awy to find them by that ID unfortunately

[clever lagoon]

can you give all the GO's unique names? If not.. perhaps you could store name + parent's name+ grandparents name.. etc...

[left violet]

Thanks @clever lagoon @hard viper for the answer

[quaint rock]

you can just register all of them with a system that can do the lookup by id for you

[zinc parrot]

the names will not save if I do it in play mode, and since this is for something fo ruse by other people, I want to keep the changes to the hierarchy to a minimum

[zinc parrot]

I could yeah!

[left violet]

Thanks @hard viper for the tip with Strings I heard its Bad practice I am a Junior Dev with 1 Year experience and trying to follow the Unity Path right now and just get some results and learn some techniques. I will ofc watch out for better practice in a Project where it matters.

[clever lagoon]

I do indeed use interfaces alot..but on the lineElement, rather than the list as a whole: eg. /// <summary> /// Event triggered when the pointer exits an element in the list. /// The int parameter represents the index of the element in the full list. /// Note: The prefab used (TLineElementPreFabType) must implement the ITriggerOnHover interface for this event to work. /// </summary> public UnityEvent<int> onPointerEnterEvent { get; } = new UnityEvent<int>();

[left violet]

I just dont want to overengineer and do complicated stuff for the challenges and the videos flying them through as quick as possible while playing around with stuff

[clever lagoon]

strings? I';d use an int for the "mark".
