Quick question I am getting this error You probably need to add a Rigidbody to the game object "Pinky". Or your script needs to check if the component is attached before using it. UnityEngine.Rigidbody.get_velocity () (at <a019610f26d54349b269239d6f729022>:0) for a lot of items and was wondering if there was a way to ignore a bunch or objects in one area

The code that is producing this error is this ```private void OnTriggerEnter(Collider other)
{
Debug.Log("Hit");

    //hit.transform.gameObject.GetComponent<Rigidbody>().velocity = Vector3.zero;

    If(other.gameObject.GetComponent<MyComponent>)

        var triggerObject = other.gameObject.GetComponent<Rigidbody>();
        triggerObject.velocity = Vector2.ClampMagnitude(triggerObject.velocity, SlowDownModifier); //slows down things here
}```

[rigid island]

wdym handle events ?

[pure cliff]

public method on child script.
parent has a ref to its child script, and calls child's public method inside its event trigger method

hi, I started to learn about compute shaders recently, and I cant figure out how to send an array from a c# script to a compute shader
basically I want to draw a sdf polygon using a compute shader, but controling the amount of points and its position from the c# script, does someone know how I could do that?

[oblique narwhal]

`
private void OnTriggerEnter(Collider other)
{
Debug.Log("Hit");

    //hit.transform.gameObject.GetComponent<Rigidbody>().velocity = Vector3.zero;

    If(other.gameObject.GetComponent<MyComponent>)

        var triggerObject = other.gameObject.GetComponent<Rigidbody>();

       if(triggerObject == null) return;   // <==== add this.

        triggerObject.velocity = Vector2.ClampMagnitude(triggerObject.velocity, SlowDownModifier); //slows down things here
}

`

[oblique narwhal]

Or another approach

`
private void OnTriggerEnter(Collider other)
{
Debug.Log("Hit");

    // your pasted code does not have a correct set of braces after this IF statement, 
   // I think this is a copy paste error ??? and the below line could be removed?
    If(other.gameObject.GetComponent<MyComponent>)

    if (other.gameObject.TryGetComponent<Rigidbody>(out var rigidbody))
   {
       rigidbody.velocity = Vector2.ClampMagnitude(rigidbody.velocity, SlowDownModifier);
   }

}

it keeps it in editor. doesnt keep it in build

[night harness]

Is there a better way to easily display debug text in scene other than Handles.Labels?

[prime sinew]

for that reason, you shouldnt really be using them to save values or modify them during runtime

they're not meant for that reason

[prime sinew]

maybe you can ask in #archived-shaders

[lean sail]

Json is quite easy, the code is quite literally a couple of lines

[rancid sable]

is there a way to write the following without using object? I tried having the value be Type but then it doesn't let me convert it to T

    public class NetworkPlayerInputValue<Type> : PlayerInputValue
    {
        public object value;
        public override T ReadValue<T>()
        {
            if(typeof(Type) != typeof(T))
                throw new System.Exception($"Type:({typeof(T).FullName}) is not valid for this action");
            return (T)value;
        }
    }

nvm I found a way of pushing object casting back to only at startup

[night harness]

I know you shouldn't ask to ask a question but is anyone savvy with Handles.Labels related stuff? Trying to wrap my head around them and have a few questions about how to use them in the way i want to

[lean sail]

you gotta also call some json serialize function with WriteAllText, you shouldnt need to use system.serializable

https://www.newtonsoft.com/json/help/html/SerializeWithJsonSerializerToFile.htm
this is with newtonsoft, its just taking the object and making the json string

which you then write to file

[patent tartan]

so unity uses just c sharp like no modification right>?

[lean sail]

it is c# yes, not some variation. you use the unity api on top of it to actually affect things in unity

[mossy valley]

I am assigning a gameobject in inspector. When I go to another scene and come back to that scene, that script loses reference to that gameobject. Why? Nothing happens to that gameobject I am referencing. I don't destroy it or instantiate it. It always stays in scene.

[lean sail]

this entirely in editor or you mean this is happening in play mode?

[mossy valley]

Play mode

I get 500 of these errors 😭

[lean sail]

put error pause on

[mossy valley]

Is it cuz I sometimes use await task.delay and scenes might change before that task is carried out?

So it stops everything else from working?

I tried using the cancellation token approach but I didn't understand how to do it.

[lean sail]

that could be one reason yes, although its not really possible for me to confirm this without seeing the code

what are you using await for even, ive rarely seen true needs for it in unity so far

[mossy valley]

Unity Services and For getting events to occur Step by step. Plus I use it to get delay before another task happens since it doesn't register if the next task requires the previous task to be complete.

I have replaced Await with invoking a function with delay in my other project since it is a better approach. Yet to do it in this project since the time constraint is really short and I have a lot of Awaits here 😭

[real pulsar]

hi guys,
my unity gets stuck for a few seconds

https://pastecode.io/s/o64vdvv3

I'm sending email with a picture attatchment from unity
but when i send the email
how can i resolve this problem
this is my code

[lean sail]

without proper context it really is just hard to suggest anything. I would avoid async as much as possible if you can in unity

[rustic temple]

heyy im trying to await sence loading how would i do that? i cant do await UnityEngine.SceneManagement.SceneManager.LoadSceneAsync("TheRift");

[real pulsar]

fixed it

[mossy valley]

Ah

Wait I realized that the gameobject with the script is not getting destroyed on load 😭 I dont even have the DontDestroyOnLoad on it and yet it stays. Wtf

Okay I realized that the gameobject was not getting destroyed since it had IAP Listener which was not supposed to get destroyed on load. Now it works.

[prime sinew]

the documentation for LoadSceneAsync should explain it

[rustic temple]

ah ok thanks didnt know that was a method

[prime sinew]

You.. just used it though 🤷

Hi, is it possible to keep the search window in the new Unity Search to only 1 instance... everytime I do dependency find I get a new window and I have to chase them down to close them one by one.

[prime mica]

OK guys, I'm unsure where exactly to post this as I don't really know how to find the problem or solve it. I have a project using the Unity FPS Starter pack (with the controller). For some reason the player's mouse movement gets "stuck" randomly

as in it sticks and struggles to move

[dusk apex]

Did you change anything related to code?

[prime mica]

No. I think I just fixed it though

the movement threshold in the controller cod was set to 0.01 so I just set it to 0.001

[craggy forum]

hey guys. if I use Resources.LoadAll in a static dictionary class it works fine, but when using Resources.Load in the same static dictionary, Unity quits silently - what am i missing?

[thin aurora]

Sounds like a crash. Can you share your code?

[craggy forum]

This is the previous version and that one works perfectly, but it slows the app down when you have 1k+ scriptable objects around

And these functions describe roughly what i try to achieve

[thin aurora]

If Unity quits quietly I think it's best if you try figuring out when that happends. Is it truly because of Resources.Load in this case?

[craggy forum]

Thats difficult to debug. It could also be the case that you cannot "add" to a static dictionary, once it has been instantiated

[frosty bramble]

Could anybody tell me please how I could master Unity starting from scratch. Like I know that I need to watch tutorials but how can I actually master it (In the sense of knowing game design and being able to program without constantly looking up things on Google and Youtube)

[craggy forum]

I watched a lot of tutorials and started by modifying existing project templates

[frosty bramble]

Interesting, I will try that. Thank you.

[craggy forum]

besides that a programming course does not hurt 😉

[frosty bramble]

True. But how did you move on then to your own custom projects instead of modifying existing templates? Thanks

[rocky helm]

Hello. So basically, I am making meshes at runtime to mimic glass shattering, but I have come across an odd problem. in this code snippet:

Vector3 p0 = vertices[0];
        Vector3 p1 = vertices[1];
        Vector3 p2 = vertices[2];
        Vector3 triangleNorm = (Vector3.Cross(p1-p0, p2-p0)).normalized; //Get the normal of the triangle | Some normals seem to have a value of 0,0,0
        if(triangleNorm == new Vector3(0,0,0)){
            Debug.Log(obj.transform.name);
            Debug.Log(p0); //not 0,0,0
            Debug.Log(p1); //not 0,0,0
            Debug.Log(p2); //not 0,0,0
            Debug.Log((Vector3.Cross(p1-p0, p2-p0)) == new Vector3(0,0,0)); //Always true
        } //All the y-axis are zero tho since that's what they are supposed to be for me

There are some triangles which have the normal be 0,0,0 after the calculation what, in return, breaks the mesh. It might be that the calculations for getting the normal are wrong, but I think it is correct? I know this is most likely not enough information to help me, but I don't quite know what else to give you except for a couple of the logs so feel free to ask me for anything more (these are p0, p1 and p2 in order without the Y axis since it is always 0): 0.010497 -0.002478973 & 0.011 -0.006 & 0.01098285 -0.002593712

[late lion]

I get the same result with those values. They are probably just too close together for single float precision.

But if you know all the vertices have 0 y position, then you already know the normal.

[rocky helm]

How? if the object is rotated then I can't make it be up.

The y position should stay 0 always, but because they are in a local orientation

[rocky helm]

Also no, some of those triangles have quite a big surface to break due to that

[late lion]

So the local normal of the mesh is always up. Then the world normal is the rotation of the object * Vector3.up.

Vector3 localNormal = Vector3.up;
Vector3 worldNormal = transform.rotation * localNormal;

[rocky helm]

I'll try some thing like that, but i don't need to translate it into world coords so, I think this should be fairly simple if that what you said works

holy jesus of macaroni, it works!

[abstract cypress]

Does anyone know if there is a data structure that allows accessing variables as easy as with static classes with static variables but also makes it dynamically extendable? I've tried just using static dictionaries with objects but accessing them is tedious as I need to cast each value everytime

[small trench]

You should use the generic type <T> instead
https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/types/generics

[steady moat]

Depends what you really want to do. Generic can be an option in some scenario.

public abstract class Manager<T> : ManagerBase where T : Manager<T>
{
    private static T instance = null;

    public static T Instance
    {
        get
        {
            return instance;
        }
    }

...


public class IOManager : Manager<IOManager> {}

...

IOManager.Instance

[abstract cypress]

I'm taking a look at Generic. I want to have a class that provides important variables (like game settings) to all classes while being easy to access (without the need of extensively long code), and expandable by config reader or other classes

[humble void]

I have an issue with 2 tiles of noise not aligning. Could it be this small line in the center that causes the issue?

[abstract cypress]

Is the noise a texture of a sprite and each tile is it's own sprite? The line wont be the reason but the effect of this bug. Maybe take a look at the loops in your noise function, maybe you are feeding the Perlin Noise function wrong locations hence why it's slightly offset

[humble void]

It is for terrain generation not for sprites. I have already looked at the loops and it's all fine, the points where it samples the height value are consitent and aligned, so I don't know where the issue lies, and I feel like the discrepancy in the terrain is too large for this small discrepancy in the noisemap

float[,] GeneratePerlinMatrix()
    {
        float[,] Noisemap = new float[resolution, resolution];
        
        for (int a = 0; a < resolution; a++)
        {
            for (int b = 0; b < resolution; b++)
            {
                float xSample = ((float)a / (resolution - 1) * ChunkSize + xOffset) * NoiseFrequency;
                float zSample = ((float)b / (resolution - 1) * ChunkSize + zOffset) * NoiseFrequency;
                
                Noisemap[a, b] = Mathf.PerlinNoise(xSample, zSample);
                samplePos[a, b] = new Vector3(xSample, 0, zSample);
            }
        }

        return(Noisemap);
    }

    void ConvertNmapToTerrain(float[,] noisemap)
    {
        if (currentTerrain == null)
        {
            TerrainData terrainData = new TerrainData();
            terrainData.heightmapResolution = resolution;
            terrainData.size = new Vector3(ChunkSize, HeightAmplifier, ChunkSize);
            terrainData.SetHeights(0, 0, noisemap);

            //Generate the terrain
            GameObject chunk = Terrain.CreateTerrainGameObject(terrainData);
            chunk.transform.position = new Vector3(xOffset, 0, zOffset);
            currentTerrain = chunk;
        }
        else
        {
            currentTerrain.GetComponent<Terrain>().terrainData.SetHeights(0, 0, noisemap);
            currentTerrain.transform.position = new Vector3(xOffset, 0, zOffset);
        }
    }

[abstract cypress]

Is the chunk size equal to the heightmap resolution?

[humble void]

It is not, ChunkSize is 100 and resolution is 129, however making them equal doesn't fix the problem sadly

I had another script calculate the heightmap in the exact same way and it worked, but that script was really bad and broke all the time so I am rewriting, but for some reason, the same approach doesn't work anymore

This is the old code, very messy as I said

float pointX = ((float)a / (resolution - 1) * TileSize + xOffset) * NoiseFrequency;
float pointZ = ((float)b / (resolution - 1) * TileSize + zOffset) * NoiseFrequency;

if (LayerCount == 1) //Exception for a single layer, as below code can only handle >1
  {
      Tile[a, b] += Mathf.PerlinNoise(pointX * DetailBaseValue, pointZ * DetailBaseValue) * ImpactBaseValue;
  }

[patent tartan]

Should i just learn C# before anything else about unity

[humble void]

No, learn both at the same time

[patent tartan]

like how

just try unity

[humble void]

Watch brackeys

[patent tartan]

ok.

[quartz folio]

129? Why on earth?

[humble void]

Because the terrain resolution has to be 2^(x) + 1 if that's what you mean

[rocky helm]

If I have a Vector3 point in local coordinates, that is relative to a transform and is on the same plane as the right and up vector of the transform, then how could I translate the Vector3 point to be a Vector2 point on that plane? I have looked into planes in the api, but only found how to put the Vector3 point on the plane (as a Vector3 still), not how to translate it to a Vector2. Maybe something like Transform.InverseTransformPoint is what I am looking for, but I am a little confused about what exactly it does and if it does the right thing.

[rain minnow]

I wouldn't recommend brackeys only bc most of their tutorials are random one-offs; they don't follow an inherent pattern of learning concepts

I'd watch/read a beginner c# or fundamentals course and check the pinned tabs from #💻┃code-beginner

[somber nacelle]

InverseTransformPoint transforms a local space coordinate to world space. it has nothing to do with getting a Vector2 from a Vector3. it sounds like you just care about the X and Y coordinates of the Vector3, yeah? so just drop the z coordinate and bam you have a Vector2 representing the position along the plane

[rocky helm]

Not quite so simple unfortunately, the transform may have any rotation and I know that the Vector3 is a local position relative to the transform and that it is on the plane of the right vector and the up vector

I want to treat the right vector as the x and the up vector as the y

And get local coordinates of that point, but in 2d

[rocky helm]

Also inverseTransformPoint I believe converts world coords to local coords

[somber nacelle]

ah yeah, i had that backwards. still not exactly what you've described though

[rocky helm]

Doesn't local coords mean that the x is the right vector of the transform?

[somber nacelle]

local coordinates are relative to the object's position and rotation. i'm also not entirely getting what you are trying to do here. you explain it as if the plane is relative to the transform's up and right axes, which would make local coordinates with the Z axis dropped coordinates on that plane, but then you say it isn't?

[rocky helm]

Does that mean that if I have vertex in a mesh then the x is always the rightvector of the transform the mesh is on?

[somber nacelle]

the X axis is the horizontal axis, if that is what you mean

[rocky helm]

Yes, I know it is the horizontal axis, but in a mesh, is the x axis for the vertices towards the transforms right vector?

[somber nacelle]

wtf do you mean by "towards the transforms right vector"

[rocky helm]

or is the x axis relative to smth else

[somber nacelle]

the X axis is the horizontal axis that runs left to right

[rocky helm]

oh fuck I mixed up the names of these things in different engines, I mean transform.right by "towards the transforms right vector"

so I guess yes it is that

[somber nacelle]

yes, transform.right is the vector that points along the right direction relative to the transform's rotation

[rocky helm]

Okay thanks!

[rustic furnace]

what is the difference between a class that is derived by monobehavior vs a non monobehavior class? Also, if I needed to get a variable from a non monobehavior class to a monobehavior class, how can I do that

[quartz folio]

Where does this other variable exist? You get it from whatever API produces it. If no API exists then presumably you new the class and read that instance

There are many differences between Unity Objects and not, but it's kinda irrelevant without context

[swift falcon]

Hi, I'm having an issue with my gun in a 3d fps shooter game im making. Basically when is shoot the target it registers as a hit and gets confirmed with a debug.log statement but after a certain distance (2 or 3 meters away) the shots stop getting registered and the target doesnt take damage. I've tried plying around with the max distance value and some others but i can't seem to find the solution. Any help would be appreciated.

i can send the relevant scripts to whoever wants to help

[rustic furnace]

I have three scripts,
1.One for equipping a spell. https://gdl.space/utiyudacob.cs
2.One for the stats of that spell, which is a public class. https://gdl.space/aduwijifiq.cs
3.One script that I need one of the stats of that spell (timeToDie) from 2, but getting it from the equipped spell (1). https://gdl.space/oyafewobam.cpp

I don't know how to get the variables from the public class

getComponent<2> doesn't seem to work on 3

in void shootSpell, last line

[quartz folio]

GetComponent<SpellSlots>().spells

[rocky helm]

Oh wait I'm a dumbass I forgot what I even wanted to get to in the beginning. So, since the vertices positions are not relative to the transforms rotation, but rather are in their own "coordinate space", then how can I translate the vertices to be a Vector2 with the x being how far on the transform.right the point is and y being how far on the transform.up the point is?

[quartz folio]

Object space is the same as local space. transform.right is normalized though so it's ignoring scale

[rocky helm]

But when I do Debug.Log() on the vertices positions they are not relative to the transform.right direction

[swift falcon]

anyone able to help with this?

[rustic furnace]

spells is an array

I need to find the stats of the equipped spell

[quartz folio]

What do you mean? The vertices are stored in object space and transformed by the transform, just like Vector3.right is transformed to transform.right

[rustic furnace]

I get this error and I don't know what to do to fix it

[quartz folio]

It's nonsensical, 1. you don't have a SpellStats component on an object, because 2. it's not a component!

Your equipped spell is a gameobject, it has no connection to the spell stats instance

afaik it's literally just being referenced by spell stats and SpellSlots.equippedSpell and nothing else

[rustic furnace]

so how could I declare the stats in a way so that I can access them?

[rocky helm]

If the vertices positions were relative to the transforms rotation, then doing vertex += Vector3.up should get me the same position as doing vertex += transform.up right?

[quartz folio]

as a component on that gameobject, or as a reference on a component, or in a way that you can index back into your spells array to find out which one you're talking about

[quartz folio]

I don't know what that means exactly, but no?

transform.up is in world space

it's nonsensical to add that to something that is in local space and expect anything meaningful to occur

[autumn gorge]

In my game what you do is you make like a phone, laptop, etc and you get money by people buying your product. but I don’t know how to make it so it is based on how expensive it is and what the specs are. Here is a example for what I want it to be like just it is based on specs and price https://youtu.be/ViUf0e7DMKM 3:24-4:04 top right where it says finale and units. If you could point me to a tutorial or docs or what I should do to achieve that system. Thank you

[rocky helm]

God dammit I don't know very well how to describe the problem, but maybe this is better: How would I get how far on the transform.right axis a point is?

[terse garnet]

Guys, I want to implement a transport mechanic to my character at a fixed distance but the angle according to the position of my mouse, I'm having trouble taking this angle and defining a Vector3

this is my current code, for now it is teleporting to a distance always ahead in x, how can I modify to take the angle of the mouse?

[primal wind]

transform.InverseTransformPoint(point) then get the x axis value of the resulting vector

[quartz folio]

If the point is a vertex, then it's in local space, and you would just need to check its x coordinate

But that doesn't take into account that transform.right has a world space magnitude of 1, so if your object is scaled it will be incorrect.
You can however just multiply the point by the transform's lossyScale and the x coordinate would then be the right magnitude

[terse garnet]

got it

[ocean elk]

Hey! I'm optimizing my game now. When I change display resolution on Android device in script with Screen.SetResolution GPU processing time reducing. Does it mean that I have issues with fill rate?

[rocky helm]

What is mesh.bounds.center relative to? the transforms position?

[quartz folio]

Everything in mesh is in object space, which is the same as local space

I don't really know how to help you understand the diffierent spaces, I am making a vector guide but it's got a lot of work to do before it can really cater for most things.

[late lion]

That tells you that you are bottlenecked by the GPU. Which means that even if you optimized scripts, physics, or anything on the CPU, you wouldn't see any performance improvements (unless you're also running into power or thermal limits)
While your fillrate might be the biggest culprit, everything the GPU is doing is contributing to the bottleneck. Any optimization on the GPU will improve your frame rate.

[ocean elk]

I’m new to optimizing so my questions might be too obvious for someone. Is it 100% fiilrate issue if FPS increases when I change display resolution? That’s what the course on Unity Learning says. It’s just that I don’t use difficult shaders. Almost all materials use URP Lit shader

[late lion]

Like I said, everything the GPU does contributes to the bottleneck. Reducing the display resolution will always improve GPU time, but how much depends on how much time your fillrate is taking.

URP/Lit is a complicated PBR shader. For mobile, you should use URP/Simple Lit

[ocean elk]

Thanks, didn’t know that. I’ll try all the good practices for graphic optimization then

[gray mural]

is there a method that is called just with [ExecuteAlways] attribute?

[ashen yoke]

xy problem

[gray mural]

is there a method that is called just if [ExecuteAlways] attribute reffers to the whole class?

[ashen yoke]

explain what you are trying to achieve

[gray mural]

I probably want someone to answer my question

[ashen yoke]

so far you are asking a weird question which indicates you are attempting to solve something the wrong way

[gray mural]

so probably I want to know if there is a method like Start, but that is called when Edit mode is entered, not Game mode

[ashen yoke]

you can hook into EditorApplication.playModeStateChanged

you can use Application.isPlaying

in start, awake

you can extract your own bool from playModeStateChanged

and use it globally

[gray mural]

well, start and awake are just called when play mode is entered, so Application.isPlaying doesn't make sense here

[ashen yoke]

wrong

[gray mural]

putting it in Update makes sense

[gray mural]

well, it is called after game is finished

so yes

it works as OnApplicationQuit with ExecuteAlwaysAttribute

[ashen yoke]

it is called when domain is reloaded

awake is called on everything

all prefabs all components

if you have a prefab with execute always and domain is reloaded awake will be called on it

if you have domain reload disabled it wont be called when you exit playmode

[gray mural]

it is not called when I change a script and enter unity

OnEnable is called though

and thank you for your help 🙂

[steady moat]

There is also: https://docs.unity3d.com/ScriptReference/InitializeOnLoadAttribute.html

However, because we do not know what you re trying to achieve, we cannot suggest you the best approach

[gray mural]

I am just testing things in my script + it's always great to discover smth new

[steady moat]

What are you testing ?

Because, you know, testing is made with a goal.

[gray mural]

I am trying to instantiate any enum type to set to TMP_Dropdown in OnValidate

[ashen yoke]

Start and Awake called when - loading unity, dropping prefab into the scene in editor, loading that scene in editor, opening that prefab for editing, creating prefab variant, opening prefab variant,

[steady moat]

You might want to use a custom inspector ?

[gray mural]

is it possible to set an enum there?

[ashen yoke]

thank you

[gray mural]

for what?

[steady moat]

Yes, it is.

[ashen yoke]

thank you so much, @steady moat thank you too

it seems im not worthy to be answered

at least Simferoce is

[steady moat]

lol

I feel you.

[gray mural]

what?

[steady moat]

He has been asking you to explain what you were attempting to do.

And you just straight up said no and continue to ask question.

[gray mural]

where?

"xy problem"?

[steady moat]

#archived-code-general message

[gray mural]

well, they have already solved my problem

I mean, context doesn't matter so much here

I am just testing things

serializing Type is already another problem

[ashen yoke]

that is a simple one

attach attribute with id to types you want serialized

resolve using that id

[gray mural]

no, I want to serialize a Type

[ashen yoke]

yes i understand what you said

[gray mural]

I see, I haven't understand what you have said though. Maybe you could explain it, please?

is there a documentation for this?

[ashen yoke]

no, there are libraries on github that do it

or you can do it yourself

[gray mural]

I haven't said that I need a library

[ashen yoke]

same principle attach attribute, use that attribute to resolve the type

[gray mural]

the type is always an enum

but this enum can have a different name

[ashen yoke]

if you cant attach directly because the type is in another assembly you add it to a LUT

[gray mural]

the problem is that enum isn't an object

[ashen yoke]

type is always an enum?

share code

[gray mural]

private Type optionsEnum;

//
optionsEnum = typeof(LevelDiff); // public enum LevelDiff { ... };

this is how I do it with a specific enum

but I want to be able to do it in the inspector

so that I can chose whatever enum I want

that exists somewhere in the script

it will be actually perfect if I could do it by chosing public type from script from dragged object

(as it's done in Events)

I will have to do a research on that actually

[ashen yoke]

yep same thing i said earlier

attach attribute with id

resolve using that id

you can technically use anything as id, like the type name

but id is reliable, name isnt

[SerializedTypeId("someguid")
class Foo
{
}

    [System.Serializable]
    public class SerializedType
    {
        public Type type
        {
            get
            {
                if(_type == null)
                  _type = SerializedTypeResolver.GetType(_guid);
                return _type;
            }
        }
        Type _type;
        [SerializeField] string _guid;
    }

static class SerializedTypeResolver
{
    Dictionary<string, Type> types;
    static SerializedTypeResolver()
    {
        // collect all types with SerializedTypeId
    }
    public static Type GetType(string id) => types[id];
}

class SerializedTypePropertyDrawer : PropertyDrawer
{
      // draw dropdown selector for all types with id attached
}

in simple terms

[gray mural]

I see, that's great, but isn't it then better just to find all enums?

it's even easier than finding specific attribute then

[ashen yoke]

yeah and how will you serialize it

[civic locust]

does anyone know any good tutorials on delegates? I'm trying to use them by looking through this article but I don't understand it - trying to apply it to my own code and it isn't working

article: https://gamedevbeginner.com/events-and-delegates-in-unity/

[ashen yoke]

https://www.youtube.com/watch?v=UL2XHN6uJCg&list=PLAE7FECFFFCBE1A54 playlist

[civic locust]

thumbnail pretty pog, ill have a look now

[gray mural]

[SerializeField] private string optionsEnumName;

private Type[] allEnums;

private Type optionEnum;

//
// find all enums somewhere
//

private void OnValidate()
{
    optionsEnum = allEnums.First(w => w.FullName == optionsEnumName);
}

I will have to test it

also thank you for your help 😄

[ashen yoke]

yep as i said you can do it, but its not reliable

[gray mural]

I see what you mean

[ashen yoke]

you renamed the enum, you move it, nest it, and all your serialized strings are broken

[gray mural]

yes, but the same can be with id

[ashen yoke]

no, id never changes

thats the idea

[gray mural]

if you rename an enum, you probably will rename the id too

[ashen yoke]

you never rename the id

[gray mural]

why?

[ashen yoke]

because its literally a guid string

[gray mural]

I think I shouldn't be "id123" for LevelDiff enum

[ashen yoke]

74945e6e-c72f-43eb-8312-f9c98563449d

this is the string in the attribute

a guid

[lean sail]

I doubt you'll ever look at a GUID x7x2h27js[...] and think you need to rename it

[gray mural]

how do you get this id?

[ashen yoke]

generate it any way you want

i have vs extension that inserts a new guid with ctrl+k+space

[gray mural]

I see

[ashen yoke]

you can use interactive window and Guid.New()

[static matrix]

Ok So
I am trying to have a looping level of some sorts
where after interacting with something you are warped back to the start and the level is replace, re-triggering the checks for all the various spawnables
however I think because the interactable is a child of the level, its applying the changes to the prefab?
I think?
I can also just try and have the interactable separate and just never move, that might work

[gray mural]

well, yes, it's reliable

thank you one more time

[ashen yoke]

its the same difference between unity asset databse and unreal one

i can only speak for ue4, but in it moving an asset would leave behind a "redirector" file

because assets dont have a guid attached to them

resolved by path

unity has .meta with guid

same as this attribute, meaning you can move assets anywhere

doesnt matter

even between projects

references will be preserved

[lean sail]

You'll probably have to specify more, when you say level, is this some actual GO you have or are you referring to the scene? Sounds like you are instantiating something but never grabbing the reference

[humble void]

If you generate several layers of perlin noise with increasing frequency and decreasing impact and add the resulting height values together for every position, what is a good way to insure the values stay between 0 and 1 without flattening it to much (for example I tried dividing the heighrt values by the ammount of layers and using a sigmoid function but all made the terrain very flat and basicly destroyed the detail)

[night lance]

I'd say this is a code general question; Say I have a texture2D and a rect, how can I crop the texture2D, say the start is Vector2(120, 512) and the width is 1280 and height 1280. I'd need only those pixels. I've tried googling it, but I just don't get it.

[ashen yoke]

probably something like min/max for every sample

i advice to grab LibNoise and use it instead, or at least to get a reference for blending nodes

[ashen yoke]

https://docs.unity3d.com/ScriptReference/Texture2D.GetPixels.html

[night lance]

getpixels only accepts a mipmap level as a parameter though?

[ashen yoke]

scroll down

[night lance]

ah, i see, thank you

[swift falcon]

rb.AddForce(transform.up * jumpforce);
hey could someone help me with this error

[somber nacelle]

you've already been told how to solve it

[simple egret]

No, you don't

[swift falcon]

idk what they mean

[simple egret]

Don't post in multiple channels, go learn C#

[humble void]

I don't know the maximum or minimum that is the issue and because this thing should generate (almost) infinitly in every direction, I can't wait until all values have been generated to find out what they are

[ashen yoke]

i mean you sample all layers and select max

look into libnoise it should be a solved problem already

[somber nacelle]

there are beginner c# courses pinned in #💻┃code-beginner
start with those and learn wtf you are doing so that basic info like "make jumpforce a float" actually makes sense to you

[humble void]

Ight thanks

[ashen yoke]

https://github.com/klassmann/libnoise-csharp/blob/master/libnoise/module/Blend.cs

look through modules

libnoise is basically nodes, chain them, sample the chain

its much more convenient to work with than with raw functions, you can use or write a node editor and observe the changes in real time

which means you accelerate iterations

so even if you wont use it as is, use it as a playground to create desired results

https://dhlevi.github.io/LibnoiseDesigner/

[pure cliff]

this is really messing with me, why is your array of Types called allEnums

[gray mural]

because this array contains all enums

[pure cliff]

it contains a bunch of Types

[gray mural]

also that was a small prototype snippet

[pure cliff]

are the Types all Types of various Enums?

[gray mural]

yes, but after you assign them, it will contain enums

[gray mural]

yes

every enum has its own type, so yes

[pure cliff]

I see...

why are you inflicting such a thing on yourself @_@;

[gray mural]

what do you mean?

[pure cliff]

usually holding a Type in a variable like this is a code smell unless you are doing something very fancy like making your own custom dependency injection engine

[gray mural]

there is no way to do it in another way with enums

[pure cliff]

and holding an array of Types is really far down that path

[pure cliff]

do what?

[gray mural]

collect enums

you cannot just do enum[] allEnums

[pure cliff]

what are you trying to accomplish though

[gray mural]

I have written it above

I am making a DropdownEnum script for my game

so that options of dropdown that script is attached to are the same as specific enum's items

this is the only way to do it, so

[pure cliff]

...huh?

when you say "for my game" do you mean in game, or a custom inspector in the editor?

[gray mural]

it's a script with ExecuteAlwaysAttribute

so dropdown's options will be changed in OnValidate

I am just too lazy to write all options manually

[pure cliff]

this still hasnt gotten to the "but why" part

[gray mural]

also it doesn't seem to be correct

[pure cliff]

like super high level concept: Whats the end goal?

[gray mural]

but why?

[ashen yoke]

its not

[pure cliff]

what problem are you trying to solve with all of this

[gray mural]

well, I have said it already...

[ashen yoke]

you can create a custom inspector

[pure cliff]

no I scrolled really really far up, I seriously do not understand your end goal

like what do you need this dropdown for

lets say the dropdown is working.... then what

[gray mural]

e.g. I want to have a dropdown that contains all items of LevelDiff enum

[pure cliff]

whats the FINAL goal, whats the actual thing you are trying to achieve in the end

[pure cliff]

be specific

an inspector dropdown?

[gray mural]

I will probably to lot's of enums, so I want to change their options by just writing public enum's name

[pure cliff]

why

[gray mural]

what do you mean?

[pure cliff]

like keep going down the train track

[gray mural]

TMP_Dropdown

[pure cliff]

whats the goal

[gray mural]

well.. to not waste my time by writing options for dropdowns manually?

[pure cliff]

Okay so, in game dropdown then?

[gray mural]

yes

[simple egret]

Settings menu maybe? Like quality presets, display settings (fullscreen, borderless)?

[pure cliff]

and you want to "bind" that dropdown to a specific enum, so its an enum value selector?

[gray mural]

to all dropdowns that will be connected to public enums in my game

[simple egret]

I'm trying to guess what the end goal is here

The Y of your XY problem

[gray mural]

I have said it so...

[simple egret]

No, you're too generic

[gray mural]

I think I have explained it well

also I want to learn how to do it

[simple egret]

We're missing the context

[pure cliff]

but like, the core here is you have in game dropdowns you want to have options for, and you wanna be able to map "this in game dropdown maps to that enum's option list" right

[gray mural]

yes

[pure cliff]

Like you have the FooEnum and you wanna bind "this in game dropdown has all the options for the FooEnum" yeah?

[gray mural]

exactly

[pure cliff]

aight, is it runtime mutable? Like do you need to dynamically change "This specific dropdown now is actually the BarEnum values"?

Or will it be set at edit time (what enum a specific dropdown maps to), and then never change?

[gray mural]

edit time

[pure cliff]

basically: Do you need your options for a specific dropdown to be able to change dynamically in the middle of the game

[gray mural]

it will be changed at edit time

[pure cliff]

Aight, I wouldnt use enums at all for this then

[gray mural]

no

I will probably use most enums in settings

[pure cliff]

Enums arent the right use case here, what you have done is you have tried to re-create the Localization stuff unity has

[gray mural]

Yes, but I don't use those enums just for that

[pure cliff]

Cuz for actual strings displayed to the user, IE dropdowns, you should start with normal strings (not enums), and then later you can change from a normal string to a localized string

[gray mural]

well, I have this

public enum LevelDiff
{
    VeryEasy,
    Easy,
    Normal,
    Hard,
    Extreme,
    Insane
}

public static string GetString(this LevelDiff diff) => diff switch
{
    LevelDiff.VeryEasy => "Very Easy",
    LevelDiff.Easy => "Easy",
    LevelDiff.Normal => "Normal",
    LevelDiff.Hard => "Hard",
    LevelDiff.Extreme => "Extreme",
    LevelDiff.Insane => "Insane",
    _ => string.Empty
};

[pure cliff]

yeah you have effectively re-invented the localization system

[gray mural]

why..

isn't it how it's usually done?

[pure cliff]

nah

[gray mural]

how would you do this?

[pure cliff]

now we may still be able to enums and then your solution isnt terrible but

I have to sanity check if the localization system works for const accessible stuff in attributes

[sage latch]

What about making another class that sets the values?

[gray mural]

what do you mean by localization?

[sage latch]

I'll bring up some code

[gray mural]

you reffer to me?

[sage latch]

yes

[gray mural]

well, this sentence isn't so clear to me without any code or further explanations

[sage latch]

I'll get some code in here

[simple egret]

Localization: displaying different things depending on the user's locale settings (language, formats). Translation, simply said, but evolved to other stuff than strings

[gray mural]

or you can just explain?

[gray mural]

I see.

haven't ever worked with this stuff

but it may have troubles with enums I guess?

[sage latch]

public class EnumDropdown<T> : MonoBehaviour where T : Enum {
  TMP_Dropdown _dropdown;

  void Awake() {
    _drodown = GetComponent<TMP_Dropdown>();
    _dropdown.options = Enum.GetValues<T>().Select(value => new TMP_Dropdown.OptionData(value.ToString()));
  }
}

[pure cliff]

Localization effectively is the process of mapping KeyValuePairs of "Value" to "SomeString"

[sage latch]

Then create children of this class that specify the enum type

[gray mural]

oh, anyway it isn't an issue with enums

[pure cliff]

Im trying to look up how you can GetDisplayName of enums in Unity

[gray mural]

you can translate everything in GetString, so no problem

[pure cliff]

might be an Asp.Net thing only

[gray mural]

oh, does it even work?

[sage latch]

Well you have to create child classes

[pure cliff]

MVC has an [Display(...) attribute you can put on enums to specify their human readable name

[sage latch]

because unity doesnt support generic monobehaviours out of the box

[pure cliff]

I know @hard viper found a lib for serializing Type, which is fine here if it can be narrowed down to specifically enums

[gray mural]

do I have to create all enums that I want to use with this type, or?

[sage latch]

I can show

[gray mural]

please 😄

[pure cliff]

theyd have to make a class for every individual enum which sounds like a pain

[sage latch]

I was just in a lol game

[pure cliff]

I do think a Type selector is prolly the right call here

but I think the "convert enum to string" logic can be simplified via an Attribute

unity already has a way to "nicefy" enum names sort of

[gray mural]

well, I don't think I should care about localization for my small poor game now

anyway I have almost done it already

[sage latch]

This class should work

public class EnumDropdown<T> : MonoBehaviour where T : Enum {
    TMP_Dropdown _dropdown;

    void Awake() {
        // Get the dropdown
        _dropdown = GetComponent<TMP_Dropdown>();
        // Get the values of the enum and construct a new OptionData from each
        _dropdown.options = Enum.GetValues(typeof(T)).Cast<T>()
            .Select(value => new TMP_Dropdown.OptionData(value.ToString())).ToList();
    }

    // _dropdown.value returns the currently selected index
    public T Value => (T)Enum.Parse(typeof(T), _dropdown.options[_dropdown.value].text);
}

And then create children with the specific enum type

public class LevelDiffDropdown : EnumDropdown<LevelDiff> { }

[gray mural]

I just have to find a way to get not enums from the full Assembly, but from #Scripts folder

[hard mountain]

If you want this but without the creating a child class for every enum pass, i have something too

[sage latch]

GenericUnityObjects?

wdym, generic classes? @gray mural

[gray mural]

I will have to create a class for all dropdowns

[soft shard]

Are you trying to get every enum type in a specific folder of your project "automatically", rather than manually specifying which enums you want to turn into a dropdown? (just trying to understand your goals)

[sage latch]

Yeah, but it's literally 1 line of code

alternatively you can get the GenericUnityObjects package

https://github.com/SolidAlloy/GenericUnityObjects

[gray mural]

yes, anyway.

[gray mural]

I will have to get all enums in order to find them by name

[hard mountain]

You make a component that works for all enums. The UI controller class will pass the enum type to the component and then the component can read the enum values from that

[gray mural]

amonst Type[] allEnums

[hard mountain]

It's a lot less boilerplate

[sage latch]

but you dont get type safety

i guess its a tradeoff

[hard mountain]

Yeah

[gray mural]

but can I reffer to it like this.Easy (LevelDiff.Easy) ?

[hard mountain]

Hey if I'm working with unity i have to accept that sometimes i have to deal with tradeoffs like that

[sage latch]

Yeah, this doesnt change anything about the enum

It's a completely separate class

[hard mountain]

Also i dont remember where E : Enum being a thing, am i misremembering

[sage latch]

It constrains the type to be a child of Enum

[pure cliff]

right but the whole point of code is automation so, if theres a way to not have to write extra lines of code, its usually preferable :p

[sage latch]

and thus only accepts enum values

[hard mountain]

I always thought you couldn't do it, huh

[pure cliff]

its a new constraint that got added a bit ago

[sage latch]

that's where GenericUnityObjects comes in

[pure cliff]

?

[sage latch]

https://github.com/SolidAlloy/GenericUnityObjects

[hard mountain]

Oh wait that's kinda huge

[pure cliff]

ah yeah thats the shit

@gray mural that, that right there, thats the answer

[gray mural]

?

[pure cliff]

does it even work with constraints on the generics?! 😮

[sage latch]

yeah

[pure cliff]

what Bobbo just linked

[pure cliff]

life. altering.

[sage latch]

I wouldn't call it life alterning

[hard mountain]

God i wish i found this earlier lol

[sage latch]

its more of a QoL

[pure cliff]

I would lol

[hard mountain]

It'd have saved a bunch of time for me

[gray mural]

what is it for ?

[pure cliff]

exactly your use case

when you need to be able to specify a type constraint of a monobehavior

[sage latch]

(unrelated to apples question) This is how it looks btw, it only shows the valid types in this nice dropdown

[pure cliff]

oh wait, okay so it still just creates the non generic class wrappers, it just automates creating them

[sage latch]

yes

[pure cliff]

Well... thats still pretty good I guess

it should be way better in terms of performance at least

[sage latch]

what would even be better?

[hard mountain]

Funky code generation

[pure cliff]

if unity just supported it proper bwahaha

but this does seem like as close as you can get and its pretty close

[sage latch]

yeah ig

but without some insane reflection shenanigans i dont see it happening without code gen

[hard mountain]

My only wish is for interfaces to be assignable in editor

[sage latch]

That is the dream, yes

But not going to happen

[hard mountain]

Yeah it doesn't seem possible lol

[pure cliff]

what do you mean?

oh like, that you drag and drop an interface ref

[hard mountain]

Yes

[pure cliff]

yeah itd be nice if there was an IMonoBehavior

[hard mountain]

Technically IComponent

[sage latch]

when would you ever want that though

[hard mountain]

I only remember that i needed it a few times, forgot the details

[sage latch]

MonoBehaviour has like 20 public members

[pure cliff]

yeah thats true

[sage latch]

you would need to reimplement it every time

[light rock]

default interface implementations

[sage latch]

true

i always forget those exist

[hard mountain]

Wait that's c#?

[pure cliff]

I like to just keep pretending they dont

[sage latch]

but why not an abstract class at that point

[pure cliff]

exactly, I seriously dont get the point of them

[sage latch]

if you want multiple inheritance

[pure cliff]

its like trying to progress towards C++ multip- YES exactly

[light rock]

multiple inheritance

[pure cliff]

which is not considered a great thing to have

[light rock]

well sometimes its useful

[pure cliff]

I dont remotely understand the appeal of default interface imps, it seems to violate everything C# stands for @_@;

[hard mountain]

Is default interface implementation even available in unity c#

[somber nacelle]

yes

[hard mountain]

I'm still on 2019.4 so i might not have it anyway though

[somber nacelle]

ah yeah probably not, it's a c# 8 feature

[pure cliff]

both my old and new job just straight up forbid using those til anyone could come up with an actual use case for the things, no one ever did

[sage latch]

public interface IResource {
    string Name { get; }
    Namespace Namespace { get; }
    string Location { get; }
    object Data { get; }
}

public interface IResource<out T> : IResource {
    new T Data { get; }
    object IResource.Data => Data!;
}
```This is the only use case I've met so far

(not unity)

[hard mountain]

I'd REALLY like to use it for my use case

[sage latch]

IEnumerator also has this stuff

[light rock]

the ability to add methods to an interface without breaking old code

[pure cliff]

thats not a good thing imo

[light rock]

old classes that implement it

[hard mountain]

Wait can't you just make an extension class and extend the interface

[pure cliff]

yeah that sounds like a bad idea

[hard mountain]

Why is this needed

[lean sail]

I use it in my save system to just specify the file name as => GetType().Name.
Each save file is by default saved under the class name and I dont need to specify the key in every single class

[pure cliff]

me and over like 70 seasoned veteran devs at my last job never came up with an answer to this over a whole year

[hard mountain]

Huh

[sage latch]

Implementing another interface?

Like I showed in my example?

[pure cliff]

why would you want to do this

[gray mural]

can is show enum types?

[sage latch]

yes

[gray mural]

nice

[sage latch]

To have a non-generic and generic version of the same interface

[pure cliff]

default imp is orthogonal to that

[sage latch]

orthogonal?

[pure cliff]

yes. You can achieve that result still without the weird default imp

you just re-invented the abstract class

[sage latch]

You can't inherit from multiple classes though

[somber nacelle]

interfaces shouldn't be a substitute for inheritance either though

[pure cliff]

public interface IResource 
{
    string Name { get; }
    Namespace Namespace { get; }
    string Location { get; }
    object Data { get; }
}

public interface IResource<out T> : IResource 
{
    new T Data { get; }
}

public abstract class Resource<out T> : IResource<out T>
{
   object IResource.Data => Data!;
   ...
}

[pure cliff]

yeah thats a good thing

[sage latch]

I agree

[pure cliff]

any greybeard C++ dev can prolly write an entire essay on why C#'s single inheritance system is something to celebrate, not try to circumvent

[sage latch]

but its implementations that are the problem, not the outfacing interface

[pure cliff]

whats the issue?

[soft shard]

What is => Data!;, what does the ! at the end specify?

[sage latch]

It's to suppress the null warning

[hard mountain]

Null safety stuff

[soft shard]

Oh

[sage latch]

Crazy inheritance trees where its extremely hard to change something

[pure cliff]

its just a shorthand for declaring a get property, its the same as writing

object IResource.Data
{
    get => Data!;
}

which is a further shorthand for

object IResource.Data
{
    get {
        return Data!;
    }
}

[sage latch]

Classes needing to inherit stuff that they don't need/want

[pure cliff]

like what?

[pure cliff]

decorator pattern, strategy pattern, composition over inheritance...

[sage latch]

"composition over inheritance" yeah that's what im trying to say here

[pure cliff]

default interface imps are not composition

its weird pseudo inheritance and worse yet, multiple inheritance

its as far away from composition land as you can get

[sage latch]

Yeah, you should switch out abstract classes for interfaces

but that's not what my use case is about

[pure cliff]

well no, its not a principle of "switching out"

[gray mural]

object IResource.Data => Data!;

[pure cliff]

composition is about "owns a", not of "is a"

[gray mural]

do you want me to use that package with code you have suggested?

[pure cliff]

Static Extension Methods, and stuff like Decorator/Strategy pattern, are examples of Composition

[sage latch]

Yeah

[hard mountain]

I mean i feel like the default interface implementation is just syntatic sugar for doing the same thing with static extension

[sage latch]

Interfaces also play a critical part because they enable polymorphism

[pure cliff]

except it modifies the class but the class downstream isnt aware of this

extension methods "glass box" the logic

[hard mountain]

Can you elaborate more on this?

[sage latch]

I don't see how object IResource.Data => Data! hides anything from the children

[pure cliff]

if you add a default implementation method, the class implementing the interface now is altared

[spiral ibex]

Weird question, is there a way to prevent a component being added to a prefab/scene in the Editor?

[sage latch]

but I do get your point about default implementations circumventing the single inheritance

[hard mountain]

[HideInInspector]?

[pure cliff]

prevent it in what way?

[hard mountain]

Unless im misunderstanding

[spiral ibex]

I think I misexplained it. I want this to not be possible. I think I can do this by deliberately naming the .cs file something else.

[hard mountain]

In my currently understanding, the class implementing the interface is just as unaware of the static extension methods as the default implementation

[pure cliff]

yeah but an extension method can only access and manipulate from an "outside" perspective

[hard mountain]

If anything it's more hidden with static extension since the logic is somewhere else entirely

[pure cliff]

effectively speaking, adding a default implementation to an interface can potentially break unit tests you have for the implementing class, as its behavior is now altered

[gray mural]

yes

[hard mountain]

There's no private / public when it comes to an interface iterface though, so what does outside perspective mean?

[pure cliff]

static extension methods, on the other hand, wont do this

[hard mountain]

Ah okay

I see your point now

[spiral ibex]

My renaming the file it exists in to no longer match the class name?

[gray mural]

[ExecuteAlways]
public class Smth : MonoBehaviour
{
    private void OnEnable()
    {
        if (GetComponent<Rigidbody>()) // if any condition
        {
            Debug.LogWarning("blabla");
            Destroy(this);
        }
    }
}

[sage latch]

Are you adding the component at runtime (through code)?

[spiral ibex]

Correct

[pure cliff]

basically default imps can result in:

"what the heck, our FooUnitTests are all breaking now, but git blame is saying FooUnity.cs hasnt been changed in several months, and we mock all our interfaces for injection of dependencies so... how the hell are the unit tests breaking now?"

[hard mountain]

That makes a lot of sense thank you

[late lion]

I think [AddComponentMenu(null)] or [AddComponentMenu("")] on the class should hide it in the menu.

[hard mountain]

This is cursed

[gray mural]

if they add via inspector, it will work

they will have to invent their own condition

[spiral ibex]

empty string did the trick. It obviously is possible to still drag and drop but this is good enough, tyvm!

[gray mural]

also e.g. you cannot add BoxCollider if gameObject has Rigidbody2D

they won't be able to create an error window like unity does though

[pure cliff]

this is also a big reason why I never use inheritance for my services. it removes the possibility of code "somewhere else" changing and breaking my unit tests that have been glass box'd.

Inheritence: Foo inherits from Bar. FooUnitTests started breaking, despite Foo.cs never being altared... reason: Bar.cs got altared.

Composition: Foo depends on an IBar, but for the unit test we use a MockBar (usually via Moq) that we inject in, that way the only code that gets tested in FooUnitTests is purely the code inside of Foo.cs

However... if Foo : IFoo and now you throw default imps into the mix... that all goes right out the window D:

[gray mural]

but do I still have to create a class for every enum?

[sage latch]

No, you can just add the EnumDropdown<T> directly onto a GameObject

[hard mountain]

Yes i very much know how great interfaces are, i just didn't know the details about static extension like you explained earlier

[pure cliff]

So technically yes but the library handles "automatically" generating those for you

[gray mural]

the dropdown you have suggested?

[gray mural]

I see

[pure cliff]

if you pick a new one itll prompt you to save the .cs file somewhere

[sage latch]

It doesn't even prompt you

[gray mural]

I wonder how they have done it just with c#

[sage latch]

It's open source, you can look in there

[gray mural]

I am too bad in generics to understand it

[hard mountain]

Well we know that it's code generation

[pure cliff]

brings back to this statement, that library is an example of "something very fancy" hahaha

[sage latch]

It's probably just:

$"public class {ClassName}_{Type.Name} : {ClassName}<{Type.Name}> { }"
```written to a file

[hard mountain]

I.. did that just now lol

[pure cliff]

the fancier part is the nice browser of namespace/assembly, including with handling the constraints

[hard mountain]

It was this

Made it because i had too many settings in my app

[sage latch]

Yeah of course

but you could a prototype with just that

and saving to a random folder

[sage latch]

i18nKey??

[hard mountain]

I have localization for my project

[sage latch]

Oh

I was so confused

[hard mountain]

I18n key just specify where to look for the translated text for each option

I18n is for internationalization (dumbest shorthand ever)

[spiral ibex]

Ngl that piece of code looks very weird to me

[sage latch]

C# before generics

[gray mural]

this is crazy, it offers me all enums in Assembly to select from

[hard mountain]

This is before i knew about genericunityobject lol

[pure cliff]

holy shit THATS WHAT THAT MEANS?!

[hard mountain]

Yes

[pure cliff]

oh my god I have seen that so many times and I never realized thats what that was

[lean sail]

"yea its spelled.. I uh theres 18 letters, then an N"

[pure cliff]

I always thought the I was an l

[lean sail]

thatd be l10n!

[pure cliff]

this is up there with k8s

[spiral ibex]

kates?

[pure cliff]

kubernetes

[spiral ibex]

who tf..

[lean sail]

l10n = localization

definitely some of the worst naming conventions ever

[pure cliff]

I hate the "stick a number in the middle of it" approach

[hard mountain]

I find myself guilty for using it

[spiral ibex]

I don't think I ever thought "you know what, my variables should have digits in them"

[lean sail]

i hate it but id hate typing a 20 character word at the same time

aint no way im spelling i18n without a typo

[hidden flicker]

How do I convert a Transform[] to a List<Transform>

[spiral ibex]

.ToList()

[hard mountain]

.ToList()

[pure cliff]

.ToListen()

[hard mountain]

But dont to it very often because memory

[pure cliff]

got it, dont listen to people cuz I have a bad memory 😮

[hidden flicker]

"Transform[] does not contain a definiton for ToList"

[sage latch]

new List<Transform>(Transform[]) 😏

[hard mountain]

You have to add using System.Linq;

[hidden flicker]

...Wouldn't that make an array of arrays

[hidden flicker]

Thank you

[sage latch]

No, that would be new List<Transform[]>()

[lean sail]

no, the array is being passed into the parameters of the list

[hard mountain]

No that'd be new List<Transform[]>

[gray mural]

but why does it give me a warning now?

public class DropdownEnum<T> : MonoBehaviour where T : Enum

[sage latch]

Is the file named DropdownEnum?

[urban wigeon]

Pls guys help me

[gray mural]

yes, Dropdown.cs

[leaden ice]

wouldn't you need a separate file and class like:
LevelDiffDropdown : DropdownEnum<LevelDiff> ?
LevelDiffDropdown.cs

[urban wigeon]

I exported my first charcter from blender as test, ma boy is clipping through the floor 💀

[sage latch]

rename it to exactly DropdownEnum.cs

[hard mountain]

They're using Genericunityobject to avoid that

[gray mural]

that's a package they have recommended me

[shrewd vessel]

would this be the place to ask about TMPro questions? or should i go up to the beginner?

[gray mural]

oh, sorry, it's DropdownEnum.cs already

my bad

[leaden ice]

never heard of it but I'll back off then since idk what it's about

[pure cliff]

the lib in use automatically generates that, its pretty cool

[leaden ice]

I see

[pure cliff]

Im definitely gonna add it to my toolbox, it seems super handy

[spiral ibex]

https://github.com/SolidAlloy/GenericUnityObjects
This?

[hard mountain]

Yes

[pure cliff]

depends how common vs zany of a thing you are doing with said TMP

[sage latch]

hmm that's weird

[hard mountain]

That's what kesomannen recommended

[gray mural]

oh, shouldn't it be like this instead?

[pure cliff]

the bottom one is right I believe

[sage latch]

It looks like you're using quite an old version of unity. Does it meet the requirements?
Unity 2020.2 or higher
.NET 4.x (when using Unity 2021.1 or lower)

[hard mountain]

Oh no

[sage latch]

No, the bottom one needs a type "Add ..." to be pressed

[hard mountain]

Okay I couldn't have used it anyway lol

[sage latch]

the top one looks correct except for the warning

[hidden flicker]

How do you remove a bone from a skinned mesh renderer

[gray mural]

no, I have .NET Standart 2.1 and 2021.3 Unity version

[shrewd vessel]

Im sure its fairly simple. Can you turn on a UI text if you reference a gameobject?

[sage latch]

oh, then the script's icon is messed up

[gray mural]

why?

[sage latch]

The warning might be a bug in the package

[sage latch]

¯_(ツ)_/¯

[hard mountain]

Is staylow the gameobject with the text?

[gray mural]

I see, well

[hard mountain]

That works i think

[sage latch]

try readding the component

[gray mural]

Thank you all for your help guys 😄 I appreciate taht

[gray mural]

tried.

[sage latch]

otherwise you can make your own class:

public class LevelDiffDropdown : EnumDropdown<LevelDiff> { }

do the job yourself

[hard mountain]

Or go the cursed route like that SettingsEnum.cs i sent

[shrewd vessel]

The debug shows it working with the collider (i have it set to trigger) but the text does not show up when i enter it

[hidden flicker]

I can't set the bones to an array, so the "get list of bones, modify it, then set" isn't working

[hard mountain]

It's probably the comparetag part then

I have never used tags in unity so I can't help you

[pure cliff]

change from GameObject to a TMP_Text at the top. And then you can just enable/disable it

specifically Staylow.enabled = true/false

[hard mountain]

Is it better to toggle the component or to toggle the activeness of the gameobject

[sage latch]

Depends

[pure cliff]

tbh I would actually expect its better to modify the culling mask of the camera :x

[sage latch]

umm

ok

[pure cliff]

thats how I go about it, get as low level as possible to minimize called logic

[hard mountain]

Jesus christ lol

[pure cliff]

(can also just modify the display layer of the thing in question)

[lean sail]

if this isnt about visibility then this doesnt do anything

[pure cliff]

it is indeed visibility

stuff like sprites and canvas and whatnot

[shrewd vessel]

It's still not toggling, i Thinkbuddy was right and the Tags might be the issue

[sage latch]

But if the canvas is overlay mode then it doesnt work right?

[pure cliff]

still works, your camera has a bitmask for what it can "see" vs not

[hard mountain]

Why are you comparing tags though, what's the idea

[lean sail]

ah i couldnt find the context scrolling up

[pure cliff]

breakpoint in the method and attach the debugger, see whats up

[shrewd vessel]

That if a helicopter goes too high they get a warning before they die

[hard mountain]

Yes but the way i see it you don't need the tags bit at all

Maybe?

[sage latch]

still works for me even if I disable my camera

[lean sail]

the component would be faster to disable

[shrewd vessel]

ill try removing the tags

[pure cliff]

wait what, really? huh.

[hard mountain]

I see

Good to know

[sage latch]

But if you have children that could be weird

[hard mountain]

That has never been a performance issue for me but that's cool

[sage latch]

really depends on what you want

[lean sail]

from my experience though, its never really been a choice vs component or whole object, because of the different use cases

[pure cliff]

yeah like if its a button you prolly wanna disable the whole object, cuz the text of the button is a child

though I think the canvas button has a method to handle this?

[sage latch]

no?

[steady moat]

UI is not render through the camera.

[sage latch]

• depends on the canvas mode

[hard mountain]

It shouldn't display anything in play mode i think

[sage latch]

it does

[hard mountain]

Huh

[hidden flicker]

Can anyone help with removing a bone from a skinned mesh renderer :(

[sage latch]

I can't really help, but did you see this thread?
https://forum.unity.com/threads/problem-removing-bones-from-a-skinnedmeshrenderer-at-runtime.204746/

[hidden flicker]

Yes

[hard mountain]

I don't have any experience with these so can't help you

[steady moat]

Obviously

[lean sail]

what you see in the game view is what you'll pretty much see in play mode, it does display still.

[hard mountain]

Ah right i forgot

Yeah canvas without camera will just render in overlay mode okay

[lean sail]

i think the "No cameras rendering" is the exception, or you can toggle if its shown i forget the specifics

[shrewd vessel]

Got it working, thanks guys! mixture of the Tags and then using TMP_text. heres the end result

[leaden ice]

that OnTriggerEnter is definitely bugged

it's going to happen regardless of the tag

[hard mountain]

Just warning you that the if statement is only guarding the debug.log

[leaden ice]

because of where you put the log

[shrewd vessel]

i just moved around the bug on the "ascent" and seeing if it was they tag that was giving me the error, turns out the tag was wrong and i reverted it back to the play and had no issues

[leaden ice]

what

idk what "ascent" is

but your if statement is structured incorrectly

that's all we're saying

you need to swap the { and the Debug.Log lines

[hard mountain]

You probably want Staylow to activate only when the tag match from the looks of it

And that's not the case right now

[shrewd vessel]

ahh i see what you're saying

[hidden flicker]

Still can't figure out bone removal :(

[hard mountain]

I really don't know how to help you

The only thing i can say is best of luck looking for a solution

[hidden flicker]

Yeah I'm asking people here who might know more, not specifically you

Thank you though

[hard mountain]

Working with unity can be frustrating like that sometimes

Last time i went insane because unity's inputfield implementation was so bad I had to extend it myself and modify the behaviour (i even used reflection to modify a private variable)

[steep herald]

is the [defaultexecutionorder] attribute reliable on all platforms?

[glossy ledge]

APPLE SIGN IN ICW PLAYFAB
Today I finished an update for the Android version of my game.
And tomorrow I will go back to the Apple IOS version.

Now the behavior, shop stuff etc works fine, but last time I tried, I really got stuck with the mandatory Apple Sign in and the fact that you have to push everything through XCode does not make it any easier ...

So I was wondering if anyone here had any experience with this specific issue and if they could give some pointers or links to resources (preferably a video where someone shows how it works) .

Then hopefully , if (and probably when) I get stuck with this (BLEEP) again, I have some straws to pull on 🙂

As always thanks in advance!!!

[shadow hedge]

if i wanted to make a AR and VR game. would it be better to work on the same project but in different scenes, or should i just make individual projects for both. Also they would both work the same. same scripts assets, etc

alright thanks

[hard viper]

it's called ClassTypeReferences

it serializes the identity of a class into an object of type TypeReference, and also lets you narrow the scope. Such as only allowing types that derive from a given baseclass, or implement a certain interface.

no bullshit typing strings, either. All type names get validated, so no spelling errors.

it uses reflection, obvs

[knotty sun]

Serializing type is easy. Type.AssemblyQualifiedName is a string, that is all you need

[hard viper]

[field: SerializeField] public ClassTypeReference tileMono { get; private set; }```
Cool. So you can do that in even less effort?

[knotty sun]

I see no Type there

[hard viper]

tileMono is an object with a Type field

tileMono.Type is the type that it corresponds to

and it comes with a property drawer

[knotty sun]

so
ClassTypeReference<TileMonobehaviour> tileMono
would not do the same?

[hard viper]

TypeReference is not a generic

[knotty sun]

why not?

[hard viper]

it doesn't need to be

it just has a Type field. That's all you need

[knotty sun]

if it's using reflection it should be

this is a typical c++ hack for something that c# solved long ago

[hard viper]

actually I don't see System.Reflection. I thought Type was in the reflection namespace

so it doesn't use reflection

[late lion]

Eh, it's the entry point to Reflection. Pretty much everything in it is Reflection.

[hard viper]

so ClassTypeReference does NOT use System.Reflection. The property drawer DOES

I assume this is so it can be fast as shit during runtime

[late lion]

It's still serializing a string, and needs to use Reflection to resolve the type from the string.

[hard viper]

that's what I assume is going on

that it uses reflection only in editor

anyway. it works great. super simple. strong recommend

[zealous karma]

Hi lovely ppl. I wanna ask you for help. Im making a little raft where the player can move freely and control the boat when interacting with the steer by pressing e. Does anyone know any type of video tutorial for a almost complete beginner on how to enter/exit a vehicle and how to steer the boat by rotation? Pls DM or poke me, I would be really gratful

[eager wagon]

hi, i have a question, why if i decelerate a 5 elements array (public bool[] cd = new bool[4];) unity says no and make it 4, crashing the game when i try to change it via teh editor

[rigid island]

what is decelerate a 5 element array ?

[lean sail]

im guessing that is supposed to mean declare

[dusk apex]

Count starts from zero

That's a four element array 0-3

[lean sail]

5 elements array but you wrote new bool[4]; which is the size

[dusk apex]

4 is the length (delimiter)

[eager wagon]

damm i see i have a problem with teh names

[rigid island]

the important take away is taht arrays start from index 0

[lean sail]

this entirely depends on your game, you could probably something similar by looking at entering/leaving car tutorials. Pretty sure ive seen a few of those existing
Though theres so many different ways of movement, you'll likely not find something thats exactly what you want

[eager wagon]

5 elements

but unity editor only displays 4

[rigid island]

u wrote 4

[lean sail]

yes because you wrote new bool[4], which is the size

[rigid island]

as size

[eager wagon]

public bool[] cd = new bool[4];

[rigid island]

this should be inside #💻┃code-beginner

[lean sail]

we understand and we are telling you whats wrong!

[dusk apex]

That's four elements

[eager wagon]

thats teh problem

[dusk apex]

.

[eager wagon]

should be 5

and its 4

[rigid island]

so write 5..

[eager wagon]

thats teh problem

[lean sail]

i feel like this is a troll

[dusk apex]

5 would be bool[5]

[eager wagon]

i write 5 and it doesnt change

[rigid island]

cause it already serialized with 4

[eager wagon]

i can write 5000 and still 4

[dusk apex]

That's simply the defaults

You'll have to reset the component or modify it from the inspector

[eager wagon]

what defaults

[rigid island]

when you serilized it in the inspector

[eager wagon]

if i modify from teh inspector teh game crashes

[dusk apex]

When you create the instance (add the component), the default values are used.

[rigid island]

can you show video

[dusk apex]

Thereafter, they're independent of the default values assigned during declaration

[eager wagon]

i dont have any tool

[rigid island]

https://getsharex.com/

[eager wagon]

wana call??

[dusk apex]

Unless you're doing so during runtime or it's an editor script, this should not be so.

[rigid island]

or use windows screen recorder or OBS

[eager wagon]

istalling

[rigid island]

which version of unity btw

[eager wagon]

2021.3.25f1

[eager wagon]

not, i do it before

[autumn gorge]

Can anyone help me?

[dusk apex]

It shouldn't crash then unless you've got assets that are doing improper stuff with serialization

[eager wagon]

idk tried now with other array and isnt happening

[dusk apex]

This is the coding channel, you might get more help in #💻┃unity-talk

[autumn gorge]

K thx

[eager wagon]

i didnt touched nothing, and now its solved, should this be a bug report?

[marble swift]

what could be the reason that like 1/10 times my code work and the other times not. im not clicking anything and right after starting im getting argumentNullException Value cannot be null

[dusk apex]

We'll not know without seeing the errors and code.

[marble swift]

i have two thousand lines of code🙃

[eager wagon]

probably a gameobject whit nothing assigned

[dusk apex]

It could just be the statement cs if (Random.value < 0.1f) Crash();

[eager wagon]

dont miss the semicolon

[marble swift]

would get recognized by the ide(rider for me), wouldnt it?

[marble swift]

will check again

but why would it work then flawlessly sometimes

[eager wagon]

if teh editor know there is a missing semicolon, why dont put the semicolon

[dusk apex]

How could we possibly know?

[river sentinel]

So, why is my Player-layer object apparently treating another player-layer object as a collision-layer object? When player-layers, according to my physics2D settings, players can only interact with collision, not themselves.

[dusk apex]

No, there isn't a known issue that's specific to your case that you've not told us about yet that's happened before.

[rancid sable]

are you missing a collider that's still set to the other layer?

[marble swift]

just wanna know some typical error causes like not assigning any delegate functions in the awake function when referencing another object

[river sentinel]

I don't think so. I've checked over numerous times now.

[marble swift]

it doesnt say theres a missing semicolon. it wouldnt compile then

[dusk apex]

It's likely your fault and not Unity. It's just easier to blame the API when things aren't working as expected.

[river sentinel]

some children are on default layer but that shouldn't collide with anything given my settings

[marble swift]

i never blamed unity. just asking for help here

[rancid sable]

if any of the children have colliders, then that would cause it. if you are using raycasts in any part of your code, you may be missing a layermask

(assuming the children with colliders are on the default layer)

[pure cliff]

Race Condition

[dusk apex]

We cannot help you without information. Randomly crashes 10% of the time without further context implies "is this a Unity issue" which can be yes or no - likely not though.

[pure cliff]

Thats usually a race condition, Id bet on it

Whats the line of code that is throwing the null exception?

[dusk apex]

NRE means something was null

[marble swift]

see. i didnt know thats a thing. thanks a lot

[river sentinel]

they do not, only the player and collision objects have colliders. And I have castfilters for checking walls and ground that filter out the player.

[pure cliff]

its likely a race condition between 2 things.

Thing 1 assigns the value
Thing 2 tries and uses it.

If sometimes rarely Thing 2 wins the race... NRE

[dusk apex]

I haven't seen the error or code. It can be anything at this point.

[rancid sable]

then I'm out of ideas without source code/video or something

[rancid sable]

building off of this, if you aren't using both the awake and start methods to order initialization of components and accessing things on other components, that might be the problem

RELEVANT: Three layers are made for this project atm. Player, Collision, and Floor Collision. Player objects use the Player layer, collision meant to be stood on goes on the Floor Collision layer, and walls are tied to the Collision layer. groundFilter only focuses on Floor Collision and wallFilter only focuses on Collision.

public ContactFilter2D groundFilter;
public ContactFilter2D wallFilter;
    private float groundDistance = 0.05f;
    [SerializeField] private float wallDistance = 0.2f;
    private float ceilingDistance = 0.05f;
    [SerializeField] private float wallBuffer;

    CapsuleCollider2D touchingCol;


    RaycastHit2D[] groundHits = new RaycastHit2D[5];
    RaycastHit2D[] wallHits = new RaycastHit2D[5];
    RaycastHit2D[] ceilingHits = new RaycastHit2D[5];

CapsuleCollider2D touchingCol;

private void FixedUpdate()
    {
        IsGrounded = touchingCol.Cast(Vector2.down, groundFilter, groundHits, groundDistance) > 0;
        IsOnWall = touchingCol.Cast(wallCheckDirection, wallFilter, wallHits, wallDistance) > 0;
        IsOnCeiling = touchingCol.Cast(Vector2.up, groundFilter, ceilingHits, ceilingDistance) > 0;
    }``` (I'd include an error message but it's semantic)

this is why I heavily avoid using Awake/Start on monobehaviors, if I have to sit and start specifying what order stuff happens in, that way lies spaghetti town

Showing the error is very important

Show us the console error

[rancid sable]

sorry, I haven't done much with 2d.

could someone else help Zwataketa out?

Self initialization in Awake and acquiring data from others in Start should be enough to avoid most race conditions.

[pure cliff]

define "treat", like they are rigidbody colliding?

[dusk apex]

It's an Editor serialization error #↕️┃editor-extensions
And specifically with use of the Find statement

Which can very likely return null

I prefer more finessed control where I use methods being called by 1 single orchestration overhead to drive everyone else, therefore the order things get called in is explicitly defined by the stack trace itself
