[somber nacelle]

by definition that no longer makes it an auto property and would therefor require being a full property with an explicit backing field

[light rock]

oh youre right actually i forgot

[plucky fulcrum]

Enabling opaque textures in urp makes everything in the game completely black

why

[somber nacelle]

this is a code channel

#archived-urp

[lucid valley]

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

[gray mural]

well, actually yes, it's the first time I see it

anyway, it won't work if I do like this:

[field: SerializeField]
public int x
{
    get;
    set => Debug.Log("works");
}

[lucid valley]

no, as thats no longer an auto property

[gray mural]

still need an additional field

[gray mural]

I see, but it doesn't make sense in our context, because I wanted to do something when it's set

as it's usually done in e.g. OnValidate

[knotty sun]

why is that not an auto property?

[mild karma]

By definition i think. https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/auto-implemented-properties

[lucid valley]

^

[leaden ice]

then you need a separate explicit backing field and serialize that

[gray mural]

sounds hard

I just should call a public method when changing a field

[gray mural]

or using smth like this with all variables

it should be modified though

[leaden ice]

you literally wrote an example of it above. It's not hard

[leaden ice]

this is no different from the property

[knotty sun]

So which rule is that code violating?

[gray mural]

a method is better in this example.

[somber nacelle]

it's a compile error

an autoproperty cannot have validation code

[knotty sun]

that is different, not the reason given

[mild karma]

None, it’s just not an auto property by definition

Not that it’s wrong

[knotty sun]

yes, I'm being pedantic, but, hey, this is programming, pedantic rules

[broken light]

so I have this in my editor script:

        SerializedProperty _meshes;
        void OnEnable()
        {
            _meshes = serializedObject.FindProperty("_meshData");
        }
        public override void OnInspectorGUI()
        {
            base.OnInspectorGUI();
            Debug.Log(_meshes.arraySize);
        }

and in my scriptable object i have:

        [SerializeField]
        Mesh _meshData;

Yet it doesn't seem to work as I get this error Retrieving array size but no array was provided

What am i doing wrong here?

[leaden ice]

show the full error stack trace?

[broken light]

Retrieving array size but no array was provided
UnityEditor.SerializedProperty:get_arraySize ()
MeshDescriptorEditor:OnInspectorGUI () (at Assets/Editor/MeshDescriptorEditor.cs:17)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

[leaden ice]

I would guess that _meshData is not actually an array or list

In fact clearly it's not

[broken light]

oh shit

[leaden ice]

        [SerializeField]
        Mesh _meshData;```

it's a Mesh

[broken light]

oops

i forgot 😄

thanks for that

[elfin tree]

Does a Camera.gameObject that is .SetActive(false) use a non-negligible amount of resources?

[knotty sun]

no, active false does not mean release of resources

[lean sail]

You could profile it to see if you notice any difference. The question itself is kinda odd, but 1 extra camera in your scene probably affects literally nothing performance wise

[rigid island]

huh?

2 cameras is quite expensive

[elfin tree]

Yeah but like a small amount of memory I'd assume

[elfin tree]

Only one being active at a time I mean

[knotty sun]

depends on your camera and the platform

[lean sail]

That was under the assumption only 1 was on at a time yea since they said setting it inactive

[rigid island]

yeah just realized 😅

[broken light]

how do i get my custom struct out of my serialised property ?

i got :
var descriptor = _meshes.GetArrayElementAtIndex(i);
then
var test = descriptor.managedReferenceValue as MyStruct;

but that doesn't work

i cant figure out how to do it for structs

[leaden ice]

objectValue iirc

https://docs.unity3d.com/ScriptReference/SerializedProperty-objectReferenceValue.html

[green radish]

How might someone add a description like this to a custom datatype?

[rigid island]

Summary with /// it creates template for you usually

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/xmldoc/recommended-tags

[green radish]

tried this and there's still no description when hovering over the datatype

and removing the /// makes the code invalid

oh wait I think I see what the problem might be

nevermind, still nothing

I thought maybe it was changing the second <summary> to </summary>

but that didnt change anything as it stands

[green radish]

so it should go above the thing it's a summary of, like this?

[rigid island]

your first picture was wrong because it had no closing tag

[green radish]

ah

[rigid island]

yes you can use it above anything pretty much

[green radish]

still not getting a description for some reason

[rigid island]

did you save ?

[green radish]

yes

saved, went over to a script that was using it as a test, hovered and screenshot

[rigid island]

weird

[rigid island]

restart VS? lol

idk

what version you using ?

[green radish]

I reformatted the line to be /// <summary>Test.</summary> to be more space efficient

rather than three lines

[rigid island]

should work fine

[green radish]

2023.1.9f1

[rigid island]

anything xml in /// should be valid afaik

[rigid island]

no such visual studio

[green radish]

oh sorry, thought you meant Unity

[rigid island]

unity is irrelevant here lol

[green radish]

Visual Studio 2022

which should be the latest one as far as I know

[rigid island]

yes ur good

[hard viper]

I have a physics-related code concern. I put the equivalent of 100 goombas on the screen. They send collision callbacks, but do not send force. If they all overlay, my framerate plummets because I get 100^2 onCollisionStay callbacks. Are there any usual approaches to this?

[rigid island]

whats collisionstay do ?

[hard viper]

Assume I made a very light but necessary OnCollisionStay(), and I cannot stop the player from putting 100 goombas into a little hole

[rigid island]

OnCollisionStay iirc runs similiar interval FixedUpdate?

i could be wrong tho

[hard viper]

mostly, if enemy is overlaid with something that should hurt it, kill the entity

sould send messages

because it's a generic script, that would also handle something like a fireball

[rigid island]

idk it might be easier to have something else manage the death messages like a main goomba manager that only recives an event oncollision with a specific tag/component ?

onstead of using OnCollision stay you use oncollision enter? or triggers ?

[green radish]

wasnt necessary, I figured out that the problem is that, for some odd reason, if you have a line making the datatype serializable, the summary must be above that, or else Visual Studio throws a fit and refuses to acknowledge its existence

[rigid island]

ah you had serializable attribute above it

yeah it probably thought you wanted to try to Serialize the summary or something

[hard viper]

I have both, but the function needs to check something to know it has noting to do oncollisionStay

but it needs to do that 10,000 times per frame

[rigid island]

can you share code OnCollisionStay method maybe?

[hard viper]

that line where we check twice speeds everything up by 2x, because those Actions are null. and they are null every frame.

if I could, I would just block out that whole function if both Actions are null, so it doesn't need to check OnCollisionStay every frame.

[green radish]

oh, that kinda makes sense

order of opperations and all that

[tepid brook]

Hi guys i have sometime a problem when i check if something is null and when i put an item in the current array there is no erreur like that

if (inventory[i].item != null)
{
  slot.GetComponent<InventorySlot>().AssignItem(inventory[i]);
}    

yep

but sometime its working so i don't understand ahah

[rigid island]

slot could also be null or you don't have InventorySlot on it

[tepid brook]

no its every time null

[rigid island]

use debugger 🙂

[tepid brook]

i've change to
if (inventory[i] != null)
and im gonna see if its working every time

i check if there is an item or not in the list but when i start the game to test the chest is empty so it null every time

[lean sail]

have you actually initialized the array or list

[tepid brook]

ofc if its working ^^

[terse garnet]

guys, how can i make a dash movement on mobile? on desktop i'm taking the mouse direction to direct the dash, but how can i do that on mobile?

[rain minnow]

Instead of the mouse position, take the touch position . . .

[terse garnet]

i tried but not worked

I will show

[rain minnow]

Is it similar to your previous code for the mouse? I guess we'd have to see exactly how you dash . . .

[misty jasper]

Hey if possible I could use some help with the input system rn

it's bugging out on me and I dunno how to fix it

[terse garnet]

like this?

function Dash

[rigid island]

buggin out isn't very helpful or descriptive, also #🖱️┃input-system would be probably a better channel

[cosmic rain]

No. That doesn't explain what you try to achieve. It explain what I already know.

[misty jasper]

thanks

[hard viper]

i guess I’m wondering how Mario maker can let you have 200 goombas on one square, and the game doesn’t chug

[rigid island]

dozens of smart engineers who know their own engine

[hard viper]

maybe I need to split enemy collision callbacks between enemies and non-enemy entities?

then goomba raycasts forward to see if it needs to turn

idk is 200 raycasts per frame viable? or too much for unity?

or maybe a trigger collider? but idk if a trigger collider with 200 things in it will also give me 200^2 callbacks if everything is in a blob

[plucky karma]

And some dozen lives by their curse to support their old legacy codes....

[night harness]

@hard viper atleast for goombas, you wouldn't need to actually know it hit a wall. just check if it moved more in that direction compared to last time it tried to move, if it didn't, turn it around

[hushed notch]

So I'm working through some of Valem's tutorials regarding hand presence, and we're putting these scripts on "Right Hand Model" etc. But, given that these scripts aren't referencing the parent game component directly, and simply have public fields to fill with scripts and references, is the placement of a script on a game object somewhat arbitrary in these situations?

[plucky karma]

I know it's possible to exclude plugins and foldier using .asmdef to say Exclude this plugin from building on specific platform. However, how can I exclude plugins and folder base on preprocessing directives? E.g.

#if FULL_GAME_ACCESS

// code will be used in full product but not use in any demo product

#endif

I don't want to go through all of the plugin scripts and manually add preprocessing directive, because then that would violates the plugin's term of agreement. (Cannot ship modified source code)

[cosmic rain]

Not entirely sure what you mean. Can you provide relevant screenshots for more clarity?

[cosmic rain]

Why would you need to modify the plugins? You only need the preprocessor wherever you're using that plugin in your code. The plugin code itself is either included or not.

[hushed notch]

I guess my question is a little more meta than concrete; i have it all working.
But my question is more about in situations like this, could the "Animate Hand on Input" script be placed elsewhere yet still function with the correct references?

[broken light]

does any one know how to paginate my array of elements for a custom inspector such that it paginates before it creates a scrollbar ?

[plucky karma]

It depends. You can have a script that house reference to all of the appropriate game objects you wish to interface in code.

E.g. You can have a script that depends on the object you apply to

// this attribute will tell unity that any gameobject that have this script must have AudioSource, or unity will add them for you when you attach! (Note it does not assign when it is already attached to the gameobject before adding this attribute.)
[RequireComponent(typeof(AudioSource))]
public class MusicBox : MonoBehaviour {
  // because of the attribute, I will be responsible for the audio source.
  private AudioSource _src;
  // for whatever reason this object may be, Maybe I want it to move on sound source, but using this just an example of optional filler requirement.
  [SerializeField] private GameObject speakerGO;
  
  // awake is called before start - acquire component within itself.
  void Awake() {
    // I expect this gameobject to have AudioSource, or we'll have problems!
    _src = GetComponent<AudioSource>();
  }
  
  // start called after awake - acquire reference(s) outside this object scope.
  void Start() {
    // This guy could be null, but would prefer to assign something!
    if( !speakerGO && transform.childCount > 0 ) {
      speakerGO = transform.GetChild(0).gameObject;
    }  
  }
}

[plucky karma]

If I do add preprocessor - how could unity retains the reference information? E.g. if the plugin offer new variable types, but need to remove it upon compilation, I don't want to lose the reference when I need to compile for full game access?

[cosmic rain]

Assuming you don't exclude it from compilation in the editor, it shouldn't lose any references. When the build is compiled, the correct defines for the specific platform are set.

[plucky karma]

Forgot to mention - I'm adding the preprocessor compilation during preprocess build process - By calling this method - https://docs.unity3d.com/ScriptReference/PlayerSettings.SetScriptingDefineSymbols.html inside IPreprocessBuildWithReport https://docs.unity3d.com/ScriptReference/Build.IPreprocessBuildWithReport.html

[cosmic rain]

Builds don't affect the editor environment.

[hushed notch]

Yeah, I figure if there's a script that references the attached Gameobject direclty it makes a lot of sense, i guess it's a choice of organizational structure otherwise

[plucky karma]

Must be a good reason to remove public access from designer that'll use your script...

[cosmic rain]

You can sort of use the same principles as with code, namely - the single responsibility principle. It makes sense to put scripts on objects that they "belong" to semantically.

[hard viper]

goombas turn around if they touch each other

this just helps spread enemies out to avoid single death blobs with like 50 enemies

[lapis ruin]

(repost since i couldnt get this answered last time around)

Currently I have a whole Rigidbody based first person movement system, and the only problem with it is that it struggles to go up any drastic change in height such as a stair. To counter this, I want to make the player sort of always keep a .5 unit offset from the closest ground to their feet (so floating, pretty much) with the use of a Raycast detecting the ground below them. The way to do this would be to continuously change the Y of the player from the Y of the point of raycast collision plus that .5 unit offset mentioned previously by changing the player's transform. So I did this, it works fine. But is there any way I can fix the jittering?

let me know if my explanation of the whole thing is confusing

[hard viper]

what jittering?

you used a raycast to always keep a fixed distance from floor

[leaden ice]

Modifying the transform directly will always be problematic when mixed with Rigidbody motion

A better approach would be to add forces as appropriate when on a slope to counteract the influence of the slope

Also if possible use a flat ramp collider rather than jagged stairs

[lapis ruin]

thing is, this has been a good solution for stairs too. but yeah, i guess the ramp solution works too. just been trying to find a way around it if possible. i might have to cut my losses on this

[hard viper]

i do a little bit of both. my rigidbody applies forces primarily to go along slope. but I also move transform directly very tiny distances if my collider gets disconnected from floor, which happens if “running off” a slope

but i don’t have stairs. only slope

moving my transform can work smoothly because it is only ever a very small correction, done infrequently

[lapis ruin]

you know what

fuck stairs, man

[hard viper]

that’s the spirit

just DRAW stairs

stairs.jpg

[night harness]

A majority of games don’t use real stairs like that for movement

its all collider ramps

[leaden ice]

Stairs are actually a really complex physical interaction

Not modeled well with capsule shaped people

[hard viper]

stairs are notorious for being hard as shit

[night harness]

Actual stairs are for visuals and if your fancy feet IK

[lapis ruin]

further proves that stairs are just racist against capsule kind

[hard viper]

stairs.png

apply texture

done

[lapis ruin]

I'm gonna keep messing around with that whole fixed distance from floor thing, see if i can change some things to stop the jitter and other problems im having with it right now

if not then

we'll have to fuck the stairs

not in that way but

im sure you get it

thank you all

[versed condor]

Does anybody know how to fix character controller sticking to cielings whn you jump?

[rigid island]

maybe its spiderman

[leaden ice]

Haven't encountered that one 🤔

Actually I guess you're probably simulating velocity yourself? I would just zero out the y velocity if you detect a collision with the ceiling

[neon junco]

By chance is ur floor and ceiling the same prefab and the tag on both are set to ground?

[versed condor]

yea but my char controller doesnt use tags to detect anything

[rigid island]

nahh its this prob what Praetor said

[leaden ice]

E.g. with https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnControllerColliderHit.html

[versed condor]

I will try that

[leaden ice]

You can use the collision normal to see if it was the ceiling. The normal will be facing downwards

[hard viper]

i agree with navarrone

rebrand to spiderman

[rigid island]

the next spiderman unity on mobile

Trying to do marching squares and I just can't seem to get my vertices and indices working. There is almost certainly a mistake in this method, but I can't work out what it would be. ```cs
public static SimpleMesh<Vertex,uint> GetMeshForSquareIndices(NativeArray<byte> SquareIndices, NativeArray<int3> Positions, float HalfWidth)
{
SimpleMesh<Vertex, uint> Mesh = new SimpleMesh<Vertex, uint>(Allocator.Temp, 8 * (uint)SquareIndices.Length, Allocator.Temp, 12 * (uint)SquareIndices.Length);

int VertIndex = 0;
uint IndexIndex = 0; // The worst name of any variable ever!

for (int i = 0; i < SquareIndices.Length; i++)
{
    byte SquareIndex = SquareIndices[i];
    int2[] Vertices = VertexTable[SquareIndex];
    uint3[] Indices = IndexTable[SquareIndex];

    for (int vi = 0; vi < Vertices.Length; vi++) // loops over vertices for the specific square index and adds them to the mesh
    {
        Vertex CurrentVertex = new();
        CurrentVertex.Pos = new float3(Vertices[vi], 0) * HalfWidth + Positions[i];
        Mesh.Vertices[VertIndex] = CurrentVertex;
    }

    for (int ii = 0; ii < Indices.Length; ii++) // loop over indices for the specific square index and add them to the mesh, with correct vert offsets
    {
        Mesh.Indices[ii + (int)IndexIndex] = Indices[ii].x + IndexIndex;
        Mesh.Indices[ii + (int)IndexIndex + 1] = Indices[ii].y + IndexIndex;
        Mesh.Indices[ii + (int)IndexIndex + 2] = Indices[ii].z + IndexIndex;
    }

    VertIndex += Vertices.Length;
    IndexIndex += (uint)Indices.Length*3;
}

return SimpleMesh<Vertex, uint>.FromRange(Mesh, 0, (uint)VertIndex, Allocator.Persistent, 0, IndexIndex, Allocator.Persistent);

}

You would probably want to put a breakpoint and examine step by step. I usually use async methods with gizmos to animate slowly and debug points visually as well.

[cosmic ermine]

Thanks I forgot breakpoints exist lol!

Just tried to compile my first unity app and i'm hitting a breakpoint here.

you should use the visual studio / rider debugger for the C# code

hey guys, I was wondering if any of you know how to change how the camera in unity's scene view rotates? When I rotate I want it to go left and right from my perspective, but instead it spins my camera the other way. Pretty frustrating.

camera scene view is not a coding question

[modern creek]

If I want to do some drag-to-select stuff in my 2d game, should I draw the box and capture input in a UI layer object? Or is there a better way to do this? In the video above, "UiHud" has a GO called "InputCaptureImage" which is a 0% alpha image over the entire screen so I can capture pointer down/up/drag.

[misty drum]

i was just working on my own selection tool, i ende dup making the box in the game layer rather than UI, and added a collider2D to the image that captures selectable colliders when ti drags over them

[modern creek]

oh, that's a nice idea.. or I could even do both.. instead of the box, the tiles (in my example) or units, or whatever existed in worldspace .. could receive the "you've been selected" event

the box in world space could even be visible, so i wouldn't need to do anything in the UI layer at all

[misty drum]

im probably a worse programmer than you lool, i just do stuff that requires the least mixing of code lol

[modern creek]

it's a good idea, though

[misty drum]

i also used a line renderer for the box outline, make sit look nice

[modern creek]

as it is, I'd need to translate a lot of UI layer coordinates to world space coordinates

[misty drum]

yeah thats why im trying to do as much of the game a si can without a canvas

anythign that interracts with the world anyway

[modern creek]

my tentative plan was just to make a 9sliced image for this selection box, but i'm finding i'm already doing a lot of translation from UI space (scaled by canvas scale) to/from click space and to/from grid space

hm, the only problem i see is the selection volume might appear weird if you're zooming in/out..

[misty drum]

 private void SetLineRenderToBox(Vector2 startPos, Vector2 endPos)
    {

        //Sets position of each linerender line's vertex point
        lR.SetPosition(0, startPos);
        lR.SetPosition(1, new Vector3(endPos.x, startPos.y));
        lR.SetPosition(2, new Vector3(endPos.x, endPos.y));
        lR.SetPosition(3, new Vector3(startPos.x, endPos.y));
        lR.SetPosition(4, startPos);

        //Adjusts line's start and end width to stay the same width durring camera zooming
        lR.SetWidth(startLineWidth * (cameraMain.orthographicSize), startLineWidth * (cameraMain.orthographicSize));

        //sets sprite renderer gameobject(fillSprite) to center of select box, and scales it to touch the lines of the line renderer (rectangle only)
        fillSprite.position = (startPos + endPos) / 2;
        fillSprite.localScale = startPos - endPos;

    }
```fillSprite is just a gameobject with a sprite renderer and my collider

[modern creek]

oh manually drawing the box

[misty drum]

        //Adjusts line's start and end width to stay the same width durring camera zooming
        lR.SetWidth(startLineWidth * (cameraMain.orthographicSize), startLineWidth * (cameraMain.orthographicSize));

[modern creek]

hm... I'll have a think on this. I think there's pros/cons but it never occurred to me to do it directly in worldspace

[misty drum]

yeah my box is jsut a sprite that fills the positon between where ym mouse starts dragging, and where it currently is/ends being

[modern creek]

how are you capturing the initial click and startPos?

[misty drum]

uh, lemme check lol

i got soem messy logic in here for now while i test shit, but this

 //Sets initial Position of Drag Box if drag SHIFT operator key is pressed and mouse has been clicked down
        if (Input.GetKey("left alt") && Input.GetMouseButtonDown(0))//SHIFT  |  LMB
        {

            if (debugMode) { Debug.Log("Drag Down"); }
            selectStartPos = screenToWorld.MouseWorldPosition;
            selectEndPos = screenToWorld.MouseWorldPosition;

            selectionBox.SetActive(true);
            if (debugMode)
            {
                foreach (Ship i in selectedShips)
                {
                   i.VarSelectable.IsSelected = false;
                }
                selectedShips.Clear();
            }

        }

        //Sets Updated End Position of drag Box as long as LMB is held down
        while ((selectionBox.activeInHierarchy) && Input.GetMouseButton(0))//LMB
        {
            if (debugMode) { Debug.Log("Drag Hold"); }

            selectEndPos = screenToWorld.MouseWorldPosition;

            clickHeldTimer += Time.deltaTime;
            return;
        }

        //redundancy incase for some reason selection box is not active in hiarchy but click heldtimer is
        //Comes before ' "X" comment ' if statement below for Execution bug
        if (!selectionBox.activeInHierarchy && Input.GetMouseButtonUp(0))//LMB
        {
            clickHeldTimer = 0;

            selectionBox.SetActive(false);
            if (selectedShips.Count > 0)
            {
                foreach (Ship i in selectedShips)

                    i.VarSelectable.IsSelected = false;
                    Debug.Log("LMB-UP Removing");
                }
                selectedShips.Clear();
            }
        }
        // "X"
        //Resets Drag Box if LMB mouse key unclicked
        if (selectionBox.activeInHierarchy && Input.GetMouseButtonUp(0))//LMB
        {
            if (debugMode) { Debug.Log("Drag Up"); }

            clickHeldTimer = 0;

            selectionBox.SetActive(false);
        }

[modern creek]

ah, yeah, I'm probably not going to go that approach (i'm assuming this is in an Update loop somewhere?)

[misty drum]

screenToWorld is my mini script for my whole project that translates mouse screen position to world position

all of this is inside a methdo that is insidea an update yeah

[modern creek]

this is OK though - I can grok this, it's good stuff, thanks

[misty drum]

using System.Collections;

    void FixedUpdate()
    {
        //sets cursor's canvas position to world vector2
        mouseWorldPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
    }

}

    //Sets all active selectables inside of fillSprite collider to selected if not already selected on highlight

            selectedShips.Remove(i);
        }       
    }

and i use the OnTrigger methods for drag box action

again, messy, cna be cleaned, but it works

[modern creek]

yup, got it.. and i'm assuming when you release, you call all those objects and IsSelected=false them

Yep, I got the concept, I just hadn't thought of using a collider and a worldspace box for a selection tool

it's good

[misty drum]

very helpful if youre just doign rts style stuff

[modern creek]

ya that's exactly what this is

[misty drum]

same D:

the drag in action

@modern creek last thing, if you use the lien renderer for an outline like i did, make sure the line renderer "SetPosition()" methods are called before your input, otherwise it wont update as you drag, idk why it does it, not bothered enough to care

[modern creek]

interesting, cool, thanks

I probably won't use a line renderer (we'll have assets for a dragging box/volume) but it's good to know nonetheless 🙂

[misty drum]

i dont like 9-slicing cuz i have camera zoom

so i like to set the width of the lines with line renderer

thats the downside of it being in world space

[modern creek]

aye - it's a point in favor of doing it in the UI layer, or in some combination of UI layer + world space

in general I don't render stuff myself.. we have artists for that 😉

[misty drum]

im just saying, if you got camera zoom, your box outline will feel weird without scaling

hense i chose linerenderer

[night harness]

how would i get the sprite off a texture2d?

[misty drum]

spriterenderer.sprite

oh, texture

[dusk apex]

Doesn't sound like a coding question

[night harness]

I'm doing it through code

[misty drum]

you tryign to null the variable, or add something into it?

[dusk apex]

This is a texture 2d https://docs.unity3d.com/400/Documentation/Components/class-Texture2D.html

Do you see any field for Sprite? No.

[night harness]

Yeah I'm aware mate, that's why I asked the question 😄

[dusk apex]

It doesn't have Sprite

[night harness]

No but like, it does

[misty drum]

pic?

[night harness]

Unless I'm misunderstanding something

[misty drum]

A Sprite is an image that can be used as a 2d object, which have coordinates (x, y) and which you can move, destroy or create during the game. A Texture is also an image, but that will be used to change the appearence of an object.

[night harness]

?

[misty drum]

youre using an image as a texture, not as a sprite

[night harness]

I don't believe so?

[misty drum]

are you trying to like, convert a texture into a sprite?

[dusk apex]

Do you have a texture or a sprite?

https://docs.unity3d.com/ScriptReference/Sprite.Create.html

Are you trying to create a sprite?

[night harness]

Both, I'm trying to get a reference of the sprite from it's Texture

[misty drum]

you cant do that at runtime

[night harness]

Why

[misty drum]

int he editor, you use an image, to create a 2D texture, that 2D texture is its own thing converted from an image.

you can make a painting with paint, but you cant make paint with a painting type of thing

[night harness]

But are sprites not saved as Texture2D's?

[dusk apex]

There are no sprite properties to be extracted

[misty drum]

if i rememebr technically no, you can convert a texture2D to a sprite, but you cant refference the original image and change it to change the texture

[night harness]

I don't understand where they exist then

[misty drum]

in the editor

you got an example of what youre trying to do?

[dusk apex]

The slicing operation likely creates a bunch of sprite assets for you - assuming those are what you're trying to access. Create your own sprite from the texture 2d if needed.

Else the assets should be in your project directory

[night harness]

Doing some code to ref. the right sprite asset I want depending on context

[misty drum]

https://forum.unity.com/threads/get-sprite-s-of-a-texture2d-at-runtime.1319121/

[dusk apex]

Pretty much.

[leaden solstice]

You can get texture from sprite, not the other way.

Multiple sprites can use same texture, thus finding sprite with texture does not make sense for general API.

You can build own Dictionary if that really is usecase

[copper star]

Does anyone know how I can offset a vector3 to be perpendicular to rigidbody rotation

currently my object moves left of the direction it is facing

[dusk apex]

Show your implementation of move

[copper star]

Oh thanks for responding, I realised I'm actually an idiot and my Vector3 was all in the X direction rather than Z, which is what I needed. However I got the jittery physics movement so I decided to try AddForce instead

[swift falcon]

How the IPointerHandle works? Like how does it get Invoked?

I thought interfaces just a contract that says "You need this method."

[cosmic rain]

They are indeed. The event systems finds components that implement the interface and invokes it's method.

[tough ravine]

can anyone reccommend a good tutorial on making sprites on blender

[lean sail]

this is a code channel, there is a blender discord

[tough ravine]

alright thanks

just got into unity

pretty cool stuff

[gray mural]

How did they do in TMP_Dropdown so that the the method is called when value is changed in the inspector if they don't have OnValidate method?

So my goal is to do the same as they have done in my code

[tired elk]

Probably a callback

[gray mural]

an UnityEvent?

[cosmic rain]

Probably a custom editor/inspector with a property.

[tired elk]

TMP_Dropdown has an onValueChanged event IIRC, and the custom drawer is probably listening this

[gray mural]

I see

I'ma do it with OnValidate then

thanks for your reply 😄

[bitter laurel]

Hello everyone. Today I ran into a problem. I have a LeaderboardManager with Leaderboard (Script) attached to it, and it is on my first scene. It worked normally until I changed to the second scene and went back to the first scene, then I got this error:
Then I checked the GameObject, and I still saw my LeaderboardVisual attached to it:
In detail, I have a code block in my PlayfabManager, which is DonDestroyOnLoad:

    {
        Debug.Log(OnGetLeaderboardSuccess.GetInvocationList().Length);
        var request = new GetLeaderboardRequest
        {
            StatisticName = "Star",
            StartPosition = 0,
            MaxResultsCount = 30,

        };
        PlayFabClientAPI.GetLeaderboard(request, result => OnGetLeaderboardSuccess?.Invoke(this, new OnGetLeaderboardSuccessEventArgs
        {
            result = result
        }), error => OnPlayfabErrorEvent?.Invoke(this, new OnPlayfabErrorEventArgs
        {
            error = error
        }));
    }```

In Leaderboard - which attach to a game object that not have DontDestroyOnLoad, I have this to handle event fromPlayfabManager:

    {
        Debug.Log("Got the data from playfab:" +e.result.Leaderboard);
        playerLeaderboardEntries = e.result.Leaderboard;
        Debug.Log($"Entry count: {entries.Count}");
        if(entries.Count > 0)
        {
            for(var i = entries.Count - 1 ; i >= 0 ; i--)
            {
                PoolUILeaderboardEntry.Instance.ReturnToObjectPool(entries[i]);
            }
        }
        entries.Clear();
        for(var i = 0 ; i < playerLeaderboardEntries.Count ; i++)
        {
            UILeaderboardEntry entry = PoolUILeaderboardEntry.Instance.GetFromObjectPool();
            entry.SetLeaderboardEntry(playerLeaderboardEntries[i]);
            entries.Add(entry);
            entry.transform.SetAsLastSibling();

            //Check for leaderboard delay
            //if(playerLeaderboardEntries[i].PlayFabId == UserAccountManager.playfabID)
            //{
            //    if(leaderboard[i].StatValue != UserProfile.Instance.highscore) UserAccountManager.Instance.GetLeaderboardDelayed("Highscore");
            //}
        }

        //leaderboardVisual.Show();
        Debug.Log("Leaderboard Visual ID: " + leaderboardVisual.GetInstanceID());
        Debug.Log("This is the craziest thing i ever seen");
    }```

Now when I run my game for the first time, it worked perfectly. But when I switch to second scene and go back to the first scene, it shows the error.
Debug when error occurs, I have 2 Leaderboard Visual ID: One negative and one positive
And if an switch to second scene and go back to the first scene again, i the 3 Leaderboard Visual ID
So I'm thinking that the problem might be in the event part when there are 3 instances listening to that event.
How can I fix that 😦

[potent saffron]

Could you show us a screenshot of your DontDestroyOnLoad scene hierarchy? I think i might know what is happening

[bitter laurel]

Here is the screenshot of my hierarchy. My Leaderboard script attact to LeaderboardManager, and PlayfabManager script attach to PlayfabManager

[potent saffron]

Your leaderboardmanager is getting destroyed on scene change, and from what i assume, your playfabmanager needs a refference to it. Either make your leaderboard manager part of DontDestroyOnLoad using a singleton pattern, or program a function to get the refference on scene changes

[bitter laurel]

Yeah im thinking about making LeaderboardManager be DontDestroyOnLoad, but... I really don't want to do that because my second scene doesn't need to use that. And I think PlayfabManager doesn't need to have a Leaderboard reference, because it only Invoke an event when it gets leaderboard data from Playfab. I think the problem is when I come back to the first scene from the second scene and PlayfabManager Invoke the event, I have 2 event subscribers to that. The first one is the first Leaderboard when I start the game, the second one is the Leaderboard when StartScene is loaded again. The proof is at Debug.Log("Leaderboard Visual ID: " + leaderboardVisual.GetInstanceID()); , it shows me 2 results: Leaderboard Visual ID: -1344 and Leaderboard Visual ID: 100122.
According to what I read from Unity document here: https://docs.unity3d.com/ScriptReference/Object.GetInstanceID.html
I'm pretty sure there are 2 Leaderboards that exist when the error occurs.

And the other proof is, when I modify Playfab_OnGetLeaderboardSuccess function, with this:

        {
            leaderboardVisual.Show();
        }
        else
        {
            Debug.Log("It should not be shown");
        }

If only one Leaderboard exists, it should show the log: "It should not be shown" but I got the LeaderboardVisual show up, and that log too.

[tired elk]

Do you unsubscribe your listeners properly before leaving the scene the first time ?

[bitter laurel]

Yeah i'm not unsubscribe it. So now how can I unsub that event when i change to my second scene :((

[tired elk]

Is it your leaderboard that is subscribing to your manager ?

[bitter laurel]

yeah. Leaderboard is sub and Playfabmanager is pub

[tired elk]

Then, in your leaderboard script, you should add the unsub in OnDisable()

How do you do your subscription in the 1st place ? with a += ?

[graceful latch]

i have a first person camera system setup with the new input system and its jittery and i cant figure out why controls.player.mouselook is a vector 2 set to mouse delta

using System.Collections.Generic;
using UnityEngine;

public class MouseLook : MonoBehaviour
{
    [Range(0f, 100f)]
    [SerializeField] float mouseSensitivity;
    public InputMaster controls;
    [SerializeField] Transform playerBody;
    float xRotation = 0f;

    [Header("Clamp")]
    [SerializeField] float minClamp;
    [SerializeField] float maxClamp;

    private void Awake()
    {
        controls = new InputMaster();
        Cursor.lockState = CursorLockMode.Locked;
    }
    void OnEnable()
    {
        controls.Enable();

    }
    void OnDisable()
    {
        controls.Disable();
    }
    
    void Update()
    {

        float mouseX = mouseSensitivity / 100 * controls.Player.MouseLook.ReadValue<Vector2>().x;
        float mouseY = mouseSensitivity / 100 * controls.Player.MouseLook.ReadValue<Vector2>().y;

        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, minClamp, maxClamp);

        transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
        playerBody.Rotate(Vector3.up * mouseX);
    }
    
} ```

[bitter laurel]

Yeah I do that at Start()

[tired elk]

Then, do the same in OnDisable, but replace += with -=

[gray mural]

is there any way to set a default parameter for T ?

public class OptionSelectionField<T> : MonoBehaviour where T : Component { }

public class OptionSelectButton<T> : MonoBehaviour where T : Component { }

or do I have to create an overload?

[bitter laurel]

Hahaha, it totally worked. Thank everyone a lot <3. Love you alll

[tired elk]

Glad it solves it !

[gray mural]

I want to make its default value to be a UnityEngine.UI.Button

[tired elk]

So a default type ?

[gray mural]

yes.

[bitter laurel]

I've just learned Unity & C# for about 3 months, so there are lot of things i didn't know

[gray mural]

what is "a s" ?

[tired elk]

You'll need to define a proper class that inherit your generic unfortunately

[bitter laurel]

you can do that, which i found on internet:
public class OptionSelectionField<T> : MonoBehaviour where T : Component
{
// Default value of T is set to Transform
private T selectedOption = default(T) ?? (T)(Component)(Transform)null;
}

[gray mural]

it won't work

I have to make it work like that: OptionSelectionField field;

without <T>

but ofc it throws an error

so I have to do OptionSelectionField<Button> field

that's annoying.

anyway.

[tired elk]

What's your objective with that ?

You just want a default behaviour ?

Or is it to gain something like time typing ?

[gray mural]

as you may understand, I have fixed it using this method:

public class OptionSelectionField<T> : MonoBehaviour where T : Component { }

public class OptionSelectionField : OptionSelectionField<Button> { }

[gray mural]

just wanna make a default parameter

[tired elk]

Yeah, the normal method

[gray mural]

it's more comfortable when I don't have to specify a T

[quartz folio]

There is no such thing, what you did is how it is meant to be done

[potent scarab]

any way to let unity support opengl 2.0? (android)

[gray mural]

I see, I just wanted to ask if there was another method that doesn't require creating a new class

there isn't, yes

[tired elk]

You also can do this using IntNode = Node<int>; I think (from what I could find on internet)

[gray mural]

oh, well, yeah, that's helpful, thanks

[magic harness]

Hello guys.
I'm making some AI for my enemies, and i thought i would be a really cool idea to have a MonoBehaviour that instanciates a regular C# object for the enemies Behaviour. The C# object would be serializable of course and it would be easy for someone to change behaviour specific variables on the inspector for the MonoBehaviour script.

so.. for instance:

public enum Behaviour
    {
        Chase, Patrol
    }
    [SerializeField] private Behaviour behaviour;
    [SerializeField]private AIBehaviour currentBehaviour;

private void SetBehaviourSpecificData()
    {
        switch (behaviour)
        {
            case Behaviour.Chase: currentBehaviour = new FlockLikeChaseBehaviour(); 
                break;

            case Behaviour.Patrol:
            default: break;
        }
    }

So basically it means running the SetBehaviourSpecificData function in Edit Mode, is it possible to do something like this?

[barren stag]

You could run the function in OnValidate. You could also add the ContextMenu attribute to the function, though I think it needs to be public. The latter just creates an option to run the function in the 3 dots menu of the component in the inspector

[magic harness]

Uhm... On validate isnt really doing anything as far as i can tell. I dont really have the custom C# object showing up on the inspectorº

[steady moat]

Usually, behavior are made with a graph of ScriptableObject.

Also, note that you cannot use SerializeField for polymorphic class. You need to use SerializeReference (And you need to have an editor tool to be able to manipulate it as Unity as no built-in tool. Something like https://github.com/mackysoft/Unity-SerializeReferenceExtensions)

Finally, the pattern you are using at the moment is called Strategy Pattern. There is a ton of resources online on how to implement it in Unity. https://www.google.com/search?q=unity+strategy+pattern&oq=unity+Strategy+Pattern&aqs=chrome.0.0i512.5768j1j7&sourceid=chrome&ie=UTF-8

[magic harness]

Awesome!
The github package your linked works as i expected.
I'll definitely research a bit about the strategy pattern, thanks!

[stone scaffold]

Hello,
I have made a common "Enemy" script assigned to an enemy where if the player is inside a trigger which is above the enemy, the enemy will not move. When I add multiple enemies into the scene with the same "Enemy" script, it works fine except when the player is above one enemy, all other enemies will also not move. How can I fix this?

ok, it is over 100 lines of code tho

Not an issue.

Read the bot's message

[stone scaffold]

ohh

[steady moat]

We will need the player script as well.

[stone scaffold]

ENEMY https://gdl.space/olicehihiz.cpp
PLAYER https://gdl.space/nebovaxate.cs

the trigger checks are at the bottom of each

[magic harness]

in the enemy script, the isAbove function is checking if the player's is in a trigger, any trigger

[steady moat]

This is because the enemy looks if the player is in trigger without checking if the player is in the trigger of this particular enemy.

[stone scaffold]

isAbove() checks if the player is in a trigger

[magic harness]

exactly

[steady moat]

You want to do the check on the enemy side

[stone scaffold]

yes i managed to see that too but im not sure how to go about making it unique to one enemy

[magic harness]

make isAboce return istouching, as an example

[steady moat]

The enemy must check if it is above the player, not the player if it is above an enemy

[magic harness]

or just erase it and check IsTouching alone

[stone scaffold]

ah

so i would have to make another trigger function?

[magic harness]

does the trigger have any other functionality?

[steady moat]

I would use https://docs.unity3d.com/ScriptReference/Physics2D.CircleCast.html in the enemy.

[stone scaffold]

no, but there are two triggers in the game

one is for isTouching and the other is for isAbove

they are both in a separate layer so they dont collide

[magic harness]

seems to me like you're making this harder than it should be on yourself.
But yes, you can make another function for the isAbove trigger

[stone scaffold]

i'll see what i can do

thanks

but yes, first time coder here

[magic harness]

thats pretty good for a first time, keep it up!

[proven path]

In programming the pattern to program towards interfaces is very popular, but should I also use it in unity, or in other words, should I try creating an interface for every class that may be accessed in code, so that the class can be accessed via an interface, even if I could as well use the class type instead?

[tired elk]

It's OK to use interfaces in Unity, but you should do it if it's appropriate to your need. It's common to see interfaces in cases like IDamageable for example.

[proven path]

Alright, so I guess I should use interfaces for classes that share common functionality then. Thanks!

[tired elk]

Exactly 🙂

[spring flame]

I can't wrap my head around sub assets, scriptable objects of custom type and custom asset importers.
I want to have:

• a custom class Graph that is [Serializable] (but contains non-serializable data such as HashSets, so I have to somehow serialize it yet I don't know how for now) (Already have that)
• an asset of type something.graph which holds Graph class instance and sub-assets material.mat and shader.shader. It should serialize the material and shader
• when I create the asset (scriptable object has [CreateAssetMenu]) I want to create sub-assets for material and shader
• I want this asset to display like that in the assets:

How do I do that?

[spark stirrup]

Assets\Scripts\PullPlayer.cs(9,13): error CS0246: The type or namespace name 'PlayerMovement' could not be found (are you missing a using directive or an assembly reference?)

public PlayerMovement movement;

What am I doing wrong?

[tired elk]

What is PlayerMovement?

[spark stirrup]

a script

[tired elk]

I assume yes, but where is it defined ?

[spark stirrup]

This is defining it i thought:

public PlayerMovement movement;

[swift falcon]

Does that script exist

[spark stirrup]

Yes

[swift falcon]

Well I would check again because it cant find it

[spark stirrup]

I litterally have it open rn lol

[tired elk]

It doesn't define the class

It declares a variable of type PlayerMovement, ok, but where do you define this class ?

[spark stirrup]

Ohh the class? it's defined in the player movement script:

public class PlayerMovement : MonoBehaviour

[tired elk]

Do you have any other compilation error in your console ?

[spark stirrup]

Nope

[tired elk]

Is PlayerMovement a class you defined yourself or is it from a package ?

[spark stirrup]

It was a script from the first person template that I renamed

[tired elk]

Did you rename the file as well ?

[spark stirrup]

Yes

[tired elk]

Is it contained in a namespace ?

[spark stirrup]

Yes, but I tried doing:
using StarterAssets; and that didn't change the error at all

[tired elk]

Is by any chance this scripts stored in a folder called StandardAssets ?

[spark stirrup]

Nope, it's in a folder named Scripts

[tired elk]

can you share the !code of PlayerMovement please ?

Try closing and reopening unity, sometimes errors are hidden and show after a restart

[spark stirrup]

Yeah i have no idea. I'm referencing another script the exact same way in my script with no issues

Alr lemme try that

Nope still there

[vague sedge]

im trying to use customize unitys character controller to walk smoothly on any surface, at the moment ive ran into an issue where the character has no problem walking along the worlds z axis but when walking along the x axis as soon as the player hits 180 degrees the x axis input inverts and im not sure how to fix this, i was hoping if i sent someone my code maybe they could have a glance at it or just any advice would help

https://gdl.space/nujuwiseli.cs

[steady moat]

https://docs.unity3d.com/ScriptReference/AssetDatabase.AddObjectToAsset.html

[spark stirrup]

fixed it. Instead of doing using StarterAssets;
I had to actually make the script a part of the same namespace:

namespace StarterAssets{}

[tired elk]

That's weird, but fine

[steady moat]

Character Coontroller is not made for what you are trying to do. You should implement your own controller.

[vague sedge]

true but im just trying to figure out whats not working at the moment

[tired elk]

If you did StarterAssets.PlayerMovement it should work fine

Anyway, you fixed it and it's the most important

[steady moat]

Because it assumes that the player always move with the Vector3.up has the up direction.

[spark stirrup]

Yeah now my script is doing this:

NullReferenceException: Object reference not set to an instance of an object
StarterAssets.PullPlayer.Update () (at Assets/Scripts/PullPlayer.cs:34)

PullPlayer:
https://gdl.space/ujunagopip.cs

I tried dragging the player with the script attached into the variable slot but I can't

[tired elk]

You need to assign your movement variable

[tired elk]

Ah

[vague sedge]

so my approach isnt wrong the character controller is just fighting against me?

[spark stirrup]

Yeah I'm kinda confused lol

[steady moat]

The character controller is not made for that. So yes, it fights agaisnt you.

[tired elk]

Can you show the inspector of the object you're trying to drag into the slot ?

[rain minnow]

Does the player GameObject have the Movement script on it?

[spring flame]

I have read it, but I want to create fresh shader and material when asset is created. Should I be doing it in the OnEnable of my ScriptableObject, or maybe I should avoid using [CreateAssetMenu] and use [MenuItem("AssetDatabase/...")]? But then when I write a ScriptedImporter where do I assign the shader and material to the asset? I can't conceptually grasp what the main object of the asset is and how I write some serialization/deserialization for that

[spark stirrup]

It's called PlayerMovement but yes

[tired elk]

Is it the right PlayerMovement ? Like, if you double click it, is it the script you shared earlier ?

[spring flame]

for example why do I need to add a when creating a material asset, that should be a sub asset of my SO

[rain minnow]

Is there another script called PlayerMovement?

[spark stirrup]

Yes it is

[spark stirrup]

No

[steady moat]

No idea what you are talking about. You do not need to write any serialization for a shader or scriptable object ?

[vague sedge]

but i still dont understand specifically why it assuming to move with Vector3.up would affect it in the way ive described/shown, why move completely fine on one axis and not the other

[spring flame]

I want my custom asset that looks like something.graph and it basically looks like that:

class SomeGraph : ScriptableObject {
   Graph    graph;
   Material material;
   Shader   shader;
}

and I want the shader and material to generated automatically for that asset. They should not exist by themselves

just like shadergraph asset has it's own material

[steady moat]

When you generate the mats, shader and graph you just need to add it as an asset with the function I gave you.

There is nothing else to do.

Something like that

MyObject.Shader = myAsset;
AssetDatabase.AddObjectToAsset(MyObject, myAsset );```

[spring flame]

oh, so I don't need to create material and shader with the AssetDatabase, just use new Material() and add it to the asset?

[steady moat]

I mean, you need to create the asset on the disk as well.

new Material() is only memory.

[spark stirrup]

this fixed it:
movement = player.GetComponent<PlayerMovement>();

[tired elk]

So the inspector accept a gameObject ref but not directly a component ref... well

I'm puzzled, but glad you fixed your issue

[spark stirrup]

Yeah I am too lol

[heady iris]

these problems don't make sense. Something else is wrong.

[short ferry]

don't know if i'm in the right thread but, my level looks fine in blender but when putting the same file in unity a lot of textures don't show, there are some visual glitched etc as you can see. someone help pls?

[rigid island]

not a code question

[short ferry]

what is the right thread?

[vagrant blade]

#🔀┃art-asset-workflow

[rigid island]

#💻┃unity-talk or #🔀┃art-asset-workflow
looks like it could be the backface culling issue

[vagrant blade]

Also check for flipped normals

[tired elk]

Yeah but it's hard to pinpoint the problem without accessing the actual project

[short ferry]

don't know how to

tbh don't even know what that means, i'm kinda new to 3d unity

[vagrant blade]

There's a pin in #🔀┃art-asset-workflow regarding it. You can continue the conversation there.

I was just linking the fact I mentioned it.

so i have this piece of lines where i get the 4 audioclips from the resources folder however when i play only the first one is found. Spelling is correct, paths are correct. once i disable the first line then only the second one is found. any knows what is causing this?

[leaden ice]

what do you mean by "disabling" them?
When are you running this code?
Show the files in their folder?

[scarlet juniper]

disabling as a check so '//'

so it becomes green, just to check it

running the code in update

[leaden ice]

you mean commenting.

[leaden ice]

why? Just grab the references once in Start or Awake

or if you're hardcoding the paths anyway, why not just directly reference the things in serialized fields?

Anyway what makes you think it's not finding the others after the first?

[scarlet juniper]

oh thats called commenting thanks

i did it in start and awake but then it finds none

not even the first one

[scarlet juniper]

i want the inspector to be a lil cleaner

[leaden ice]

how do you know?

[scarlet juniper]

because it finds none

[leaden ice]

how do you know it finds none

how are you checking

[leaden ice]

So you already have these fields in the inspector?

How does this make the inspector cleaner

you can just assign them here

[scarlet juniper]

yes and i want to get rid of them

[leaden ice]

ok so

show the code

the full script

[scarlet juniper]

oh gosh

[leaden ice]

probably some other code is unassigning them

[scarlet juniper]

sure

i have no one clue of what you changed

but somehow it finds all of them now

you littarly used debugs and it works what the hell

[leaden ice]

maybe it was an issue of the script not being saved? IDK

[scarlet juniper]

i been trying this for the past hour, and have changed and saved this many times

i removed the debug and the lines are on the exact same spot

If I want a prefab that exists in world space (a sprite renderer) but I want some components on it to be rendered in UI space (like a slider or some text).. how would I do that?

(When I try to create a UI element on a non-canvas prefab, it adds a new canvas to the prefab)

worldspace text..?

I've put a canvas on my prefab and a text under that, but it doesn't show up in the scene (and I can't do layout in the prefab editor since it's in UI scale - ie, it's huge relative to my sprite)

i get one of these things where the sprite is tiny in the lower left

and the text doesn't render at all in the scene:

If I have to make two separate prefabs, one that's the "world" prefab and another that is the "UI" prefab (to show things like hitpoint sliders, name of the unit, etc) I can do that, but that seems like it's the wrong way to do it

[timid meteor]

quick question I am getting this error in my code. error CS0117: 'Noise' does not contain a definition for 'GetNoiseMap'. (here is the line for the code) noiseMapTexture = Noise.GetNoiseMap(width, height, scale); Does unity not have a base Noise? Do I need a using for it?

[modern creek]

I have it working if I set the canvas size (on the prefab) to 0 and the tmpro size to world space size.. but this leads to font sizes in world space, which is .. odd. Is this how it's supposed to be done?

[green oyster]

Can anyone tell me why label at sprite resolver isnt being set to "Entry" from "Entry_1"?

after i set the label, i print it, and it says its "Entry"

but the sprite resolver still says its "Entry_1" as shown in pic?

[leaden ice]

I guess you're referring to a different SpriteResolver than you think you are

or the label is changing at some point between the inspector being drawn and the code running

[green oyster]

it printed colour red for

sprite renderer, so its the right resolver, coz its the only one whos sprite render is coloured red

[leaden ice]

That's not exactly convincing

How about:

Debug.Log("Click here to see which resolver i'm referring to", resolver);```

when you click that log it will take you to the object it is referencing

[green oyster]

Tower3 so its the right gameobject

[leaden ice]

when you click it it highlights that one in the hierarchy?

[green oyster]

when i click any of the prints, nothing happens probably coz im on mobile 2d unity?

like usually if i clicked on print, it would bring me back to code where it was printed but nope

[leaden ice]

I don't think you put the same code as I did

for your Debug.Log

especially if you're using print and not Debug.Log

[leaden ice]

yeah that's not what I wrote

[green oyster]

yes i am, whats the difference

ah lol

[leaden ice]

there's a very specific reason I did it this way

[green oyster]

ah

[leaden ice]

it's so you can click on the log and it will highlight the object

[green oyster]

Ohhh, i thought print allowed same thing no?

[leaden ice]

print doesn't have the overload with the second parameter that my code is using

[green oyster]

Ohhh i see, alr i will try that

[leaden ice]

ok good

so then the only remaining possibility I guess is that the label is changing

or maybe your GetLabel() function is doing something weird

what does GetLabel() do exactly?

[green oyster]

its only getting "Entry" as the label

[leaden ice]

can you show more code

[green oyster]

well, gets a certain LABEL depending on the towers health, and then the label is slightly different if castle is level 1

but i have put a print in this code before, and its shown to print at return "Entry"

[leaden ice]

ok so this code has nothing to do with the "label" field in the inspector

[green oyster]

Nope, it doesnt set it

the only place where i set the label is here

[leaden ice]

so then looks like the health percent is >= 0.7f and the current castle level is level1

[green oyster]

like thats the full code if u want to see

[green oyster]

current castle level is 2, and yes its above that

[leaden ice]

you sure? Prove it

add more logs to GetLabel()

[green oyster]

Well it prints "Entry"

[leaden ice]

right

[green oyster]

if it was 1 it would print smth else

[leaden ice]

that clearly implies level is 1

oh right sorry

NOT level 1

yeah

so that's the reason

that's what the code tells it to do

I don't see what the mystery is here then

[green oyster]

Yes, it returns "Entry", which is the label that the sprite resolver should have been set to

but it hasn't

its still at "entry_1"

[leaden ice]

because you're calling a completely different function to set the label

GetLabel() with some parameter

not the same thing as resolver.GetLabel()

maybe you just wanted to call resolver.GetLabel()?

[green oyster]

i know that, no nope, getLabel is my custom function, to get a label depending on health

which returns "Entry"

which is good

the problem is that resolver label hasnt been set to that

and i dont know why, after i set it, i print it and it says its "Entry" but not in inspector

[leaden ice]

can you show the code for this other GetLabel() function?

and also what SetCategoryAndLabel does?

[green oyster]

sure, its Unitys code tho

[leaden ice]

that's a different GetLabel function

[green oyster]

Btw could it be that

[leaden ice]

oh I see this is the one with the parameter

[green oyster]

could it be because the bottom two categories

have similar named... entries

or not mhmm

[leaden ice]

I'm not really sure

tbh I'm not familiar with this SpriteResolver system

[green oyster]

so is thia bug thing

[leaden ice]

I don't really understand what it is or does

[green oyster]

within that sprite resolver

so is this a bug then

[green oyster]

One final thing i could do

is manually assign sprite renderer in some variable

and then check that sprite renderer to the one in code and see if they are same?

but tbh maybe theres no point in that

i will report this bug to unity, see if thye can fix it, coz idk

[waxen escarp]

anyone here free?need help debugging

anyone?

[vagrant blade]

Ask an actual question and find out?

[waxen escarp]

https://gdl.space/cipiyetuno.cs

well heres the code

it rotates only on horizontal, and some of the inputs are disabled

[somber nacelle]

look very closely at your VerticalRotation and HorizontalRotation methods

[waxen escarp]

ok

but the model keeps tumbling around even though ive applied all the rotational constraints

pls help

if anyone could send back a revised version and explain why it went wrong that would be helpful

[hard viper]

I'm thinking about Physics2D.OverlapArea(), but I need to know the most lightweight way to do this for my game. I specifially only need to know if there is AT LEAST one collider of a given layer in a region. I need to stop the computer from doing extra work if there are 200 colliders matching that description.

is OverlapArea the right method for this?

i don’t need to know what collider is there, nor an array/list of them. Just a bool

[gray mural]

well, OverlapArea method has a layerMask parameter

but it should be ok to use it if you just want to see any collider in the area

you can also use OverlapBox

[somber nacelle]

Did you find anything wrong with the two methods I pointed out?

[waxen escarp]

i did, the mouseX and MouseY were added to the wrong components

[waxen escarp]

am i wrong

[somber nacelle]

They both did the exact same thing

[waxen escarp]

yeah

i actually realized that i kept a backup of the project before i started using the new input system so its all good

even though it would mean 2 hours of work down the drain

😭

well thank you so much

ill try to rewrite it a bit more meticulously

[lament raft]

it used to work just fine

how do i solve this

ah

it did work

thank you!

[gray mural]

how do I add this script to the GameObject?

public class OptionSelectButton<T> : MonoBehaviour where T : Component

[green oyster]

to add a script to a gameobject, u clikc add components and then type name of script

or drag and drop

the script from its place in explorer to the inspector tab

[knotty sun]

cannot add a script with generics via the inspector

[gray mural]

well.

it just shows "OptionSelectButton"

[green oyster]

yes thats the script

[gray mural]

oh, no, it doesn't show anything

I have removed overload.

I just cannot add it

I have messed up with the package that should have controlled this thing after I have deleted it

[gray mural]

so.. no T with MonoBehaviour?

[knotty sun]

you can but you must add it via code so you can specify a T

[gray mural]

I see, not that comfortable.

thanks for help 😄

[somber nacelle]

Or create a concrete type that inherits from it with the type parameter specified

[gray mural]

not comfortable too.

anyway, I will have to create a few of them

and it will throw an error

[somber nacelle]

Well those are your options with generic MonoBehaviours

[gray mural]

I see, generic MonoBehaviour sucks.

[deep oyster]

What's the best way to create a queue of an arbitrary type?

It's mind boggling that List doesn't have a Pop function

I tried the c# Queue type but it thinks I want to fill it with objects, not my custom class I want to fill it with

[leaden solstice]

Queue<MyType>

[edgy bough]

Hello, I'm trying to make an Android app that measures the device speed with an accelerometer, but I have a small issue. I have successfully acquired the accelerometer data and removed the gravity, but it doesn't appear to show deceleration. It shows acceleration and I'm able to calculate speed based on that but it doesn't decelerate. My current code looks like this:

Input.gyro.enabled = true;
Vector3 accel = Input.acceleration - Input.gyro.gravity;

[leaden solstice]

Or Queue<object> if objects is really what you want

[deep oyster]

Nevermind, turns out I just needed to explicitly cast the Dequeued thing back into my type

[leaden solstice]

For sure, but you should try to have common interface or base type you can abstract

How does Physics.OverlapSphere work? Physics.OverlapSphere(transform.position, 6.0f, 1 << wallLayerNum) is returning an empty array when I'm definitely within 6 units of a wall

[lean sail]

Are u working in 2d or 3d?

[deep oyster]

2d

oh do I need to do overlap circle

or something

yup, there we go, Physics2D.OverlapCircle

[deep oyster]

hrrrrrm

So I've got an object on a 2d playing field, and I want to be able to quickly check what parts of the playing field that object can "see" without other objects in the way. Problem is, raycasting is... pretty expensive

Are there any fast alternatives that might work under certain circumstances

[leaden ice]

Raycasting is cheap

[deep oyster]

It definitely does not seem cheap when I need to do it dozens/hundreds of times per check

[leaden ice]

What problem are you trying to solve

Why are you doing hundreds of them

[leaden ice]

You said this but is it for rendering? Or something else

[lean sail]

A single overlap circle and math could essentially give you the same result

[deep oyster]

I am trying to create a tree for an AI that predicts player location with a series of nodes. First I raycast to the player, if I don't hit them I can't see them. Then I need to check each of the leaves to see if the AI can see that leaf from its current location, and if it can then the player is obviously not there.

[deep oyster]

I'm not sure what you mean

[leaden ice]

Not sure I understand the tree part here. Why isn't the original Raycast sufficient?

[deep oyster]

"IT" is my agent, white is my player, green is player's last "known" position

white is a tree of locations I predict the player could be based on its movement speed

[leaden ice]

You can either see the player or not

I don't understand how predicted positions relate to a line of sight check 🤔

[lean sail]

Yea sorry I dont really understand where all the raycasts come into play either

[deep oyster]

I'm not just checking if I can see the player, that's a single raycast, I'm checking if I can see each of these nodes in the white tree

[leaden ice]

Why do you care if you can see the other nodes

[deep oyster]

Because if I can see a node then I know the player is not there

And I should remove it from the tree

[leaden ice]

In this second image though why weren't most of these nodes removed a long time ago

[deep oyster]

Why would they be, I can't see any of them, the player could be in any of those places

I am creating a bot that predicts a hiding player's location and tries to look for them. It cannot and must not simply know where the player is through perfect information or there is no capacity to hide from it.

[leaden ice]

I can't help but feel like this is more of a pathfinding problem than a raycasting problem somehow

[deep oyster]

Maybe you're right but I'm not sure what to do

[lean sail]

I think u are kinda creating the problem yourself.

You shouldnt make a node then have to filter them out, dont create the node in the first place if the ai can see it

[deep oyster]

I'm doing that, but the AI's vision changes over time

[leaden ice]

Btw you can also use RaycastCommand to do a lot of Raycasts quickly with the job system

[deep oyster]

mmm

I'll look into that

like, ok, ideally, I would have some sort of continuous heatmap, update each pixel by factoring in nearby pixel's "probability" scores, remove pixels the agent can see at any given frame and add pixels the agent can no longer see

but there are no continous data structures

and I can't easily check each pixel for "visibility"

[lean sail]

This will probably be too much to actually do if you ever have a couple of enemies

[deep oyster]

Well, right now I'm just focusing on one... It doesn't even have to be super performant I can prerecord the presentation for class I just want it to work fast enough to not crash unity...

and I don't actually need pixel accuracy

I just don't want a fixed grid because that is really bad for taking into account diagonal normalized movement

[lean sail]

What's the goal for this though? This seems a bit overly complicated to have an AI reach the player

[deep oyster]

The point is I don't want it to just go straight for the player

It's a game of hide and seek tag

if you can't hide, then what's the point

maybe it is overly complicated, hell it almost certainly is

I just want to, without knowing where the player actually is, create a prediction of where he might be and go there

[lean sail]

Well your AI does know where the player actually is, if you're raycasting to it all the time

I'd say it's easier to give an AI all the information then add in stupidity to it, instead of limiting information and trying to make it super smart

Mostly because the latter isnt cheap to calculate every, especially not every frame

[deep oyster]

I guess I'll spend some time thinking how I could do that

I also don't need to do this every frame

[summer pivot]

https://hastebin.com/share/kuhebikene.csharp I've been having this issue where when I kill zombie while also getting hit by the zombie, the effects still play and my health doesnt regenerate. When I looked into it, all I noticed is my isTouchingEnemy and isTouchingPlayer boolean stays set to true.

https://hastebin.com/share/iwuquyavoq.csharp here is the other script that includes effects

[rotund knot]

So basically, say I have two Positions/Transforms, how could I find out if a positions is in the min/max area or if it is between the two other vectors? (the areas are basically perpendicular to the path of the two positions...)

[buoyant crane]

This was a fun problem, hopefully the drawing makes sense

A) Let’s figure out if it’s to the right of the min.

• Get the vector from min to max max.position - min.position
• Next get the vector from min to target target.position - min.position
• Compare the Dot Product of the two vectors. If It’s greater than 0 or equal to 0 then it’s in the zone.
  B) Let’s figure out if it’s left of max
• Get the two vectors, then dot product it to figure out if it’s in the zone

Dot product returns 0 if the two vectors are perpendicular, positive if it’s closer than perpendicular, and negative if it’s further than perpendicular
https://twitter.com/FreyaHolmer/status/1200807790580768768

[rotund knot]

Wow, thanks a lot, i'm sure i'll be able to implement it now!

[buoyant crane]

Check out the gif, it’ll help you see it. End result will look a bit like

bool InZone(Vector2 target, Vector2 min, Vector2 max)
{
   Vector2 minToMax = max - min;
   Vector2 minToTarget = target - min;
   float a = Vector2.Dot(minToMax, minToTarget); // dot product
   if(a < 0) return false; // we know that the target is behind min if it’s negative 

  Vector2 maxToMin = min - max;
   Vector2 maxToTarget = target - max;
   float b = Vector2.Dot(maxToMin, maxToTarget);
   if(b < 0) return false; // target must be behind max
   return true; // true if target is in the zone
}```

[rotund knot]

yep, that's how I just finished it up, thanks a lot for the help!

[scarlet kindle]

would collider related questions apply here?

I have disabled gravity in my top-down 2d project, because I dn't plan on using it and it was causing problems with the player falling through the floor.

I got the colliders to work with the in-game objects like enemies, walls etc. However, **now that I am trying to add isTrigger = true on the Boxcollider 2D, the collisions no longer work and the player passes through the enemy. **I see the collision trigger register in the console, so I know it is working properly. Any ideas?

Suggested answer: Don't use a trigger, use the OnCollisionEnter2D event instead?
The OnCollisionenter2D method isn't being called when they collide now... so that's an issue 😦

It works when the enemies collide with each other, but not when the player collides with the enemy. No clue what the issue is. The player is moving with rb.MovePosition which should be ok I think?

Player rigidbody (img 1)
both enemy & player have box colliders, but the enemy doesnt have a RB

Trigger does not register a collision with an incoming rigid body

It only serves as an event trigger

https://docs.unity3d.com/ScriptReference/Collider-isTrigger.html

[scarlet kindle]

right so use OnCollisionEnter2D instead of that

but, that's not working either

[celest iron]

Is the other collider also a trigger?

[leaden ice]

this is really a #⚛️┃physics question but you're using a kinematic body

[scarlet kindle]

no, i have disabled the isTrigger on both

[leaden ice]

kinematic bodies don't really collide with static objects

[celest iron]

Ah, yeah, that's a kinematic body lol, didn't see the screenshot

[scarlet kindle]

i tried changing to DynamicBody and had the exact same issue, except physics was applying in some way to the objects

collisions are working, but the OnCollisionEnter2D method is not being called

[leaden ice]

show the inspectors of both objects you expect to be involved in the collision

and also your code

[scarlet kindle]

box collider for Enemy

[leaden ice]

just show the full inspector for each

[scarlet kindle]

uh there's a lot of unrelated stuff in there

[leaden ice]

ok well I'm interested mainly in any collider2Ds and rigidbody2Ds

[scarlet kindle]

yes, the enemy doesn't have an RB at all.
Player has the RB I showed above, and the player's Collider looks like this

[leaden ice]

the enemy, if it's moving, should have a Rigidbody2D generally

[scarlet kindle]

yea its not moving atm

[leaden ice]

basically to have an OnCollision2D, you need:

• one dynamic Rigidbody2D
• each object with a NON trigger Collider2D

[scarlet kindle]

right that was my understanding as well, which is why i'm confused that it isn't working

could it have to do with player movement?

[leaden ice]

#archived-code-general message

[swift falcon]

where are you calling the code, on player or?

[scarlet kindle]

on the enemy

[swift falcon]

then he needs a rigidbody i think

the caller of those events need to have rigidbody i believe

[scarlet kindle]

player movement code is

rb.MovePosition(rb.position + direction * moveSpeed * Time.fixedDeltaTime);

[swift falcon]

ur movement code is irrelevant here

just add rigidbody to your enemy and test it using debug.log

[scarlet kindle]

the enemy was triggering collisions if they spawned on top of each other... so

[celest iron]

Show the whole script

[scarlet kindle]

they can interact with each other

[swift falcon]

that means it was working.

[leaden ice]

this is also not really a movement mthod that respects collisions

[summer pivot]

need help

[leaden ice]

should move via velocity

[swift falcon]

it will still call oncollision event no matter

[scarlet kindle]

let me try that, I think that's the issue

[celest iron]

MovePosition with dynamic body would only make it weird when colliding, but should still trigger events, no?

[swift falcon]

yes

[leaden ice]

I mean... probably but it's weird

[celest iron]

Yeah, would be better to see the whole script

[leaden ice]

we haven't seen the code yet so there might be something wrong there

[celest iron]

[swift falcon]

u need to check for tag on collision

make sure its called only on player collision with enemy

[scarlet kindle]

sorry which code do you want to see? the whole playermovement script?

[swift falcon]

he wants to see oncollision code

[leaden ice]

whichever script has OnCollisionEnter

[scarlet kindle]

thats it

[swift falcon]

u need to check for tag

of what object is he colliding with

using CompareTag() method

[scarlet kindle]

ummm

the method should trigger regardless?

[swift falcon]

thats why u had issue of

[shell scarab]

is passing a parameter with in not passing by reference? I thought in was just ref but the function cannot reassign what that parameter is?

[leaden ice]

in out and ref all pass by reference

[leaden ice]

yeah this looks fine, should show up in the console

[shell scarab]

very strange then indeed. I have a struct that appears to be coppied when passed with in, but not when passed with ref.

[leaden ice]

show the code and explain what's going wrong?

[swift falcon]

it wont because he removed rigidbody

[leaden ice]

well yeah if you remove the Rigidbody2D it won't work

[swift falcon]

he doesnt want to set it back on because it will run when enemies collide

[shell scarab]

I'll have to ask in DOTS chat I believe, it's the unity.Mathmatics Random struct.

[scarlet kindle]

i didn't remove the RB, it's on the player

Adding one to the enemy does not fix it either

[swift falcon]

u need RB on the enemy if that OnCollision event is on enemy

[celest iron]

From a posted related problem

"Hi, if you do the destroy in Update() instead of OnCollisionExit() there's a chance you'll have the grounded flag true from picking up the second collider.

However, you could have cases with a racing condition causing the flag to stay false.

To go arround it, you could instead store in a list all the colliders your ball touches at any given time in OnCollisionEnter, remove them from the list in OnCollisionExit, and check in Update wether you've got at list one ground collider in list or not.

Additionnally, this method has a major flaw that on rare occasion you wont get the OnCollisionExit, it happens sometimes when there is a lag spike and you can't do anything to prevent it (as far as I know). So what you need to do is check if your player still collides with colliders in list, if your objects are axis aligned then it's a really simple and efficient bounds.contains() check.

You could also consider raycasting/spherecasting to find out if your ball is grounded."

[leaden ice]

Passing Random in with in seems odd since almost all the functions on it will mutate it

[swift falcon]

yes it will

[shell scarab]

burst complained it wasn't passed by reference

[scarlet kindle]

If you want to see in a screenshare I can, but you're wrong

[swift falcon]

sure let me see

[leaden ice]

in creates a defensive copy probably in this case

since you are likely mutating it with a function call

[shell scarab]

yes, however i thought that was allowed when passing with in

[scarlet kindle]

i dont see voice channels do we need to go to a private server?

[leaden ice]

https://devblogs.microsoft.com/premier-developer/avoiding-struct-and-readonly-reference-performance-pitfalls-with-errorprone-net/

[shell scarab]

I've done it with lists for example and i can still add things to it. But that's a reference type, so i suppose it can work different with value types

[swift falcon]

idk never used screenshare here

[leaden ice]

yes lists are references

very different

[swift falcon]

but we dont need to use it to fix it

[celest iron]

Try checking if the enemy is destroyed on the CollisionExit too

[leaden ice]

in is specifically designed to prevent you from changing it

[swift falcon]

add rigidbodies and collide

you will see the message

[scarlet kindle]

ok well I promise you, I just added the RB to the enemy, it didn't change a thing. The player already has one

[swift falcon]

do they collide?

[scarlet kindle]

yes, they've been colliding all along, that's not the issue

the issue is the OnCollisionEnter2D method is not calling

[shell scarab]

so in the case of value types it creates a defensive copy? Thanks for the link btw! I haven't heard of defensive copies before.

[leaden ice]

only if you call a function on it

[swift falcon]

are ur rb kinematic?

[shell scarab]

Interesting, thank you!

[leaden ice]

because the compiler can't guarantee the function won't mutate the object

if all you did was read a field, you would be ok

[shell scarab]

and this is only for value types, right?

[leaden ice]

yes

[shell scarab]

awesome thanks

[swift falcon]

so? are they?

[scarlet kindle]

You were 100% right, changing it to Velocity fixed it. LMAO

totally had to do with player movement script

[leaden ice]

cool. Yeah MovePosition is generally intended for kinematic objects

[scarlet kindle]

ty sir (or madam)! you're a scholar, and ty @swift falcon for trying to help, I appreciate it

[scarlet kindle]

is there anyway I'd achieve this with kinematic objects instead? I'm not even sure I want to respect normal physics in my game necessarily

[celest iron]

Yes, but you would have to write your own collision detection

I have a script if you want to

[scarlet kindle]

im interested. I guess I need to think more on if I want to go that route or not. I mean, generally it's gonna be an oldschool RPG feel where if you run into an enemy, it triggers a new battle scene. so in that way, i'd think kinematic bodies would be a better approach. thoughts?

[celest iron]

Well, it makes the movement script way more complicated

[scarlet kindle]

I guess I could just make the enemies have a LOT of mass, right? and basically the same effect?

[celest iron]

However, it makes it more customizable

If you don't have many custom things you want to do, generally using dynamic bodies and just disabling gravity is simpler and works

I'll send you my script and the explanation.

May I dm you?

[scarlet kindle]

absolutely, I appreciate it

[astral blaze]

is it me or is it too confusing? anyway i was trying to make monitor fps counter and decided to put TextMeshPro on UI Screen, fps counter on UI works but the error is bothering me, its gotten become more annoying when i was trying to fix this

just in case its working but the error is still here

[swift falcon]

nope, i just tested it, u just realised u didn't change it to non kinematic.

[lean sail]

id start by turning on error pause then looking at the first error

[swift falcon]

MovePosition works for collisions just aswell, thats kinda trashy of you to lie just to avoid saying thanks but im not gonna interfere. you do you, just dont share misinformation intentionally

[scarlet kindle]

i did say thanks, you kinda have a shitty attitude bro! but it's all good, have a nice day

[swift falcon]

nah u lied saying its addforce is what fixed it for you when it was really setting its kinematic off

[scarlet kindle]

yes, I'm a liar and a cheat. not like it was a misunderstanding or anything! you win

[astral blaze]

im not sure what are these, im assuming i should turn on error pause?

[swift falcon]

Its all good im just putting it out,no bad blood

[lean sail]

yes turn on error pause so you can see the first thing. Also you can step through with the debugger to see whats really null

itll be more clear then

[celest iron]

What a twist

[astral blaze]

do you mind telling me where to enable the error pause?

[lean sail]

its right on your console, at the top

[latent granite]

Hello, is it possible to drag and drop from a custom script window to the Unity editor? I want to drag items from a UnityEngine.UIElements.ListView to a field in the inspector. My ListView is populated with VisualElements, I need to somehow get the object each dragged element is referencing outside the window and into the Editor, then entered into my desired component field on release.

[astral blaze]

here you go

again, still confusing tho

[leaden ice]

you didn't assign one of your fields

whatever is being used on line 33

[lean sail]

hm do you have 2 instances of this script?

[astral blaze]

this one you're talking about?

[leaden ice]

you probably have another copy of the script in the scene

[astral blaze]

oh you're right

thanks

i probably accidentally copied of the script without even notice

[swift falcon]

i was wondering if theres a better way to do this or some way to fix it? i added the && !m_FacingRight and Flip() to make it so that the empty attached to the player for a shooting point flipped with it but now the running animation wont play. Sorry if this isnt where this goes

[leaden ice]

I don't see where or how this code really affects your animations. Also !code for sharing

[dense rock]

I'm doing a velocity over lifetime in a rain particle system (see picture 2). Therefore I'm using the "random between two constants". When I try the following code, the first of the constants are modified (the rainVOLT.xMultiplier works), but for the rainVOLT.x (or z) Unity says "Particle Velocity curves must all be in the same mode"...
Also after applying the .xMultiplier, it's not random between 2 constants anymore (see picture 1).

rainVOLT.x = windDirection.x;
rainVOLT.xMultiplier = windDirection.x + 10;
rainVOLT.z = windDirection.y;
rainVOLT.zMultiplier = windDirection.y + 10;

[swift falcon]

is your runing animation moving your character?

and do your other animations work when flipped?

[leaden ice]

show more code

We don't know what rainVOLT is

[dense rock]

thats the velocity over lifetime module

rainVOLT = rainParticles.velocityOverLifetime;

[leaden ice]

and what is windDirection?

show more code please

not one line at a time

[dense rock]

just a vector 2, it isn't necessary for the problem i think

[swift falcon]

it is

[leaden ice]

definitely necessary

[swift falcon]

key part lol

[dense rock]

thats gonna take some time, give me a sec

[leaden ice]

by doing this:
rainVOLT.x = windDirection.x; that assignment is going to set the MionMaxCurve to "single constant" mode

[dense rock]

with what properties do I set both the values for random between two constants?

[leaden ice]

you would need to do something like:

MinMaxCurve xCurve = rainVOLT.x;
xCurve.curveMin = something;
xCurve.curveMax = something;
rainVOLT.x = xCurve;```

[swift falcon]

my bad oleex didnt notice u set it to y

[dense rock]

no worries but thanks ill try that ^^

[dense rock]

wouldn't the xCurve make the velocity adjust to that one curve all the time?
I'm trying to get it in random values

[swift falcon]

can u set xCurve.curveMin to some Random.Range?

[leaden ice]

this code will do random values

assuming it was already in that mode

Since we didn't modify the mode

https://docs.unity3d.com/ScriptReference/ParticleSystemCurveMode.TwoConstants.html

[dense rock]

is it random for each particle, or the same random value for each one?

[leaden ice]

random for each I assume, but this code is not changing what it was before

[dense rock]

ohh i c
