On trigger enter is the child

[swift crag]

Is the scene view set to "local" and "pivot" here?

[sullen wraith]

@swift crag yes

[swift crag]

Ah

Is there a rigidbody on the parent object?

If so, collision messages will go to it when a child collider touches something.

wait, but then the name would be wrong.

That doesn't mesh.

[sullen wraith]

@swift crag RigidD on the children

[swift crag]

try one thing: log trans.name in the RegisterLaser method

[swift crag]

I just want to make sure you're, indeed, getting two different transforms

[sullen wraith]

@swift crag

i do

[grand birch]

Yeah, the numbers on the enemy objects basically act as inputs for the math equation you're trying to solve. EX: shooting with a '2' and a '7' should produce a '2' and a '7' on the bottom of the screen where the X and Y on the screen are respectively, and then the player will either progress if the Z on bottom of the screen is a '9' (2 + 7 = 9) or recieve damage if the Z is any other number. The callback that @marsh glade mentioned makes sense, but I'm not quite sure how to implement that.

[marsh glade]

I assume you have a script that spawns these enemies somewhere ?

[distant mesa]

with newtonsoft.json, are you supposed to put "using newtonsoft.json" stuff at the top of ur script?

[grand birch]

Yes, this is it https://hastebin.com/share/ayasoyigot.csharp.

[swift crag]

Yes. That lets you omit the namespace.

It lets you write JsonConverter instead of Newtonsoft.JSON.JsonConverter

[distant mesa]

yea that doesnt work

[swift crag]

ah, it's Newtonsoft.Json. Not all-caps.

[swift crag]

Hm, I'm not sure what else would cause this. Can you share the scripts?

[distant mesa]

in the package?

[swift crag]

I'm not sure what "in the package" would be. I'm talking about adding this to the top of your script:

using Newtonsoft.Json;

[distant mesa]

ah

yeah

that doesnt work

but its in the project

[slender nymph]

are you using asmdefs?

[marsh glade]

Okay, so let's say you have two classes : A and B. If B has a callback "OnDestroyed", then A can say "I want to know when B is Destroyed, and when this happens, I want a specific method to be called, so I will subscribe to B.OnDestroyed"

[swift crag]

You may need to restart your code editor and regenerate the external project files, since you've added a new assembly to the project.

[distant mesa]

reimport?

[swift crag]

no. close your code editor, then go to preferences -> external tools and click "Regenerate project files"

then reopen your code editor

[distant mesa]

ahhh

[distant mesa]

yess

found it

[swift crag]

I would also check that the package actually shows up in the package manager window.

[marsh glade]

In this case, you can add a variable "public Action<int> OnDestroyed;" in your enemy_script class, this is your callback. To invoke this callback, you need to use the function "OnDestroyed?.Invoke(math_number);" in the part of your script where your object is destroyed.
Now, to listen to a callback, you need to subscribe to it. For example, in your enemy_spawner class, whenever you spawn an enemy_script, you can say "enemy_script.OnDestroyed += MyMethod;", where "MyMethod" is a method located within the enemy_spawner class which accepts a single parameter of type int and returns void, so something like this "private void MyMethod(int math_number) { // Do stuff here }"

However, another issue here is that your class which spawns enemies is separate from the one which contains the answer. You might need to add a reference so that the two can communicate, for example, in enemy_spawner. That way, whenever an enemy_script is destroyed, MyMethod is called with the math_number of the enemy_script that was just destroyed. With a reference to math_generator here, you can pass that value to your math_generator.

[sullen wraith]

@swift crag Made a reference to the children in the inspector and printed this at parent start. It looks correct now right?

[swift crag]

Yes, that looks right.

I presume you're just trying to get a list of all the children?

[distant mesa]

it worked

[swift crag]

If so, I wouldn't use physics at all. I'd just have the parent use GetComponentsInChildren to find all of the child components.

I should've asked about that sooner :p

I am unsure what was your problem was, though. I wonder if the rigidbodies weren't "ready" yet?

I have not seen that before.

[swift crag]

the first child's "up" direction points in the +X direction -- to the right

and the second one points in the +Y direction -- up

[sullen wraith]

@swift crag I am just trying to map out the children rotations so that if something goes in the first box it should come out on the other side with the correct rotation. Since i dont know what orientation the parent will be i need to know where the transform.up is on every child object.

[swift crag]

Yep, that's very reasonable.

[sullen wraith]

thanks for the help btw 😄

[swift crag]

Was the trigger message used to detect when a laser hit the first box?

[sullen wraith]

yes sir

[magic condor]

Uhm this wont go away

I hope this isnt the wrong place to put it

[swift crag]

Did you happen to have a field named transform in the child script?

I know you have one named name, since the name ("A" / "B") didn't match the name of the game object ("Link Child" / "Link Child 2")

[sullen wraith]

@swift crag This is my child script. Ignore the red line i am removing the transform since i dont need it any more

[marsh glade]

Callbacks and delegates

[swift crag]

huh, ain't got any other ideas.

Were the triggers happening on the very first frame of the game, or were they running later?

The method doesn't care what collider hit it, so they could be getting activated instantly

[sullen wraith]

later 🙂

I am triggering it manually at the moment

Hello. I have europe map texture and I want to make mesh from it but the problem is that the map is not rendering completely. Code

public class TerrainGenerator : MonoBehaviour
{
    public Texture2D europeMap; 

    public float heightMultiplier = 10f;
    public Material terrainMaterial; 

    void Start()
    {
        GenerateTerrain();
    }

    void GenerateTerrain()
    {
        int width = europeMap.width;
        int height = europeMap.height;

        GameObject terrain = new GameObject("EuropeTerrain");
        MeshFilter meshFilter = terrain.AddComponent<MeshFilter>();
        MeshRenderer meshRenderer = terrain.AddComponent<MeshRenderer>();


        Mesh mesh = new Mesh();


        Vector3[] vertices = new Vector3[width * height];
        int[] triangles = new int[(width - 1) * (height - 1) * 6];
        int triangleIndex = 0;

        for (int y = 0; y < height; y++)
        {
            for (int x = 0; x < width; x++)
            {
                Color pixelColor = europeMap.GetPixel(x, y);
                float heightValue = pixelColor.r * heightMultiplier; 

                vertices[y * width + x] = new Vector3(x, heightValue, y);

                if (x < width - 1 && y < height - 1)
                {
                    int topLeft = y * width + x;

        terrain.transform.position = Vector3.zero;
    }
}

[wintry quarry]

You're not setting UVs on your mesh

UVs are how textures are mapped to 3D meshes

I'm kinda curious why you're making a custom mesh here anyway if it's just a flat plane

why not use the built in Quad mesh?

[swift crag]

It's not just an image -- it's supposed to be bumpy

words are failing me right now

uhh, terrain!

[wintry quarry]

ok well - the answer is clear, there is no attempt to do any UV mapping in this code.

[swift crag]

yeah, that's going to need a fix

ah, there is indeed elevation here

Is the problem that the mesh isn't filling out that entire square?

[wintry quarry]

the rect tool is throwing me off too

[swift crag]

yeah

[queen adder]

what does this thing look like?

what am i supposed to be searching

oh wrong channel

[frozen dagger]

Guys, I’m wondering how to add animated objects in pause UI cuz time.scale = 0

[solemn anvil]

yep, it should make mesh from this

[obtuse oar]

I am trying to get a box to follow the mouse when the user clicks and drags on it, on the BoxController script I just have the OnMouseDrag() method to call the Move() method in the LevelController and then a OnMouseUp() method to call the Release() method in the LevelController. The issue is that everything appears to be recognized the way I want it to, as in the inspector values are changing correctly, but the boxes don't move.

Shown is my LevelController, I'm wondering if there is something I missed here that is causing the boxes to not move. Sorry this is my first time using a spring joint.

public class LevelController : MonoBehaviour {
    public SpringJoint2D springJoint;
    private Vector3 worldMousePos;

    public void Move(Rigidbody2D obj) {
        if (!springJoint.connectedBody) {
            Debug.Log("Moving " + obj);
            springJoint.connectedBody = obj;
        }
        worldMousePos = Camera.main.WorldToScreenPoint(Input.mousePosition);
        springJoint.connectedAnchor = worldMousePos;
    }

    public void Release() {
        Debug.Log("Released!");
        springJoint.connectedBody = null;
    }
}

[wintry quarry]

It looks like you're just attaching your object to a world space position and not another Rigidbody

that will simply anchor it stationarily in place

[obtuse oar]

hm, after messing around with it i think my initial approach is just incorrect for my goal

i did try swapping things around because i noticed that the connected body in the official unity tutorial seemed to be the "anchor"

[wintry quarry]

A typical approach is to create an invisible kinematic Rigidbody which you move around with the mouse (in FixedUpdate via rb.MovePosition) and attach the object to that with a joint.

[solemn anvil]

I don't need texture rn, I meant that the mesh does not render the entire map, only part of it

[spiral niche]

Does anyone know how to fix this?
"failed to create coreclr, hresult: 0x80004005"

[obtuse oar]

is there an easier way to do this? this feels like it's not correct Fixed it

public class LevelController : MonoBehaviour {
    public Rigidbody2D mousePoint;

    private void Start() {
        mousePoint = this.GetComponentInParent<Rigidbody2D>();
    }

[wintry quarry]

yeah that's because of your UVs

[solemn anvil]

soo what should I do

[wintry quarry]

fix the UVs

[solemn anvil]

still nothing changes

void GenerateTerrain()
{
    int width = europeMap.width;
    int height = europeMap.height;

    GameObject terrain = new GameObject("EuropeTerrain");
    MeshFilter meshFilter = terrain.AddComponent<MeshFilter>();
    MeshRenderer meshRenderer = terrain.AddComponent<MeshRenderer>();

    Mesh mesh = new Mesh();

    Vector3[] vertices = new Vector3[width * height];
    Vector2[] uv = new Vector2[width * height]; 
    int[] triangles = new int[(width - 1) * (height - 1) * 6];
    int triangleIndex = 0;

    for (int y = 0; y < height; y++)
    {
        for (int x = 0; x < width; x++)
        {
            Color pixelColor = europeMap.GetPixel(x, y);
            float heightValue = pixelColor.r * heightMultiplier;

            vertices[y * width + x] = new Vector3(x, heightValue, y);

            uv[y * width + x] = new Vector2((float)x / (width - 1), (float)y / (height - 1));

            if (x < width - 1 && y < height - 1)
            {
                int topLeft = y * width + x;
                int topRight = y * width + x + 1;
                int bottomLeft = (y + 1) * width + x;
                int bottomRight = (y + 1) * width + x + 1;

                triangles[triangleIndex] = topLeft;
                triangles[triangleIndex + 1] = bottomLeft;
                triangles[triangleIndex + 2] = topRight;

                triangles[triangleIndex + 3] = topRight;
                triangles[triangleIndex + 4] = bottomLeft;
                triangles[triangleIndex + 5] = bottomRight;

                triangleIndex += 6;
            }
        }
    }

    mesh.vertices = vertices;
    mesh.uv = uv;  
    mesh.triangles = triangles;

    mesh.RecalculateNormals();

    meshFilter.mesh = mesh;
    meshRenderer.material = terrainMaterial;

    terrain.transform.position = Vector3.zero;
}

[tame mist]

hello, I'm working on a game where there will be a bunch of cars using the same material but I want to be able to make slight changes to the albedo color and metallic on the material and only effect one car instead of all of them.
the current approach I'm using is giving me problems though.
I get "UnassignedReferenceException: The variable oldCarMaterial of CarStats has not been assigned."
but when I look at the script in the inspector it gets the correct reference of the material on the Mesh Renderer.
here is the code I'm using:

    private void Start()
    {
        oldCarMaterial = meshRendererCar.sharedMaterial;
    }

    public void RandomizeCarColor()
    {
        Color customColor = new Color(0.4f, 0.9f, 0.7f, 1.0f);
        oldCarMaterial.SetColor("_Color", customColor);
    }

oldCarMaterial.SetColor("_Color", customColor);
is where the exception is coming from

[wintry quarry]

show the full stack trace of the error

it's possible RandomizeCarColor is running before Start

btw since you're modifying the sharedMaterial you will modify the color of all the cars at once

[obtuse oar]

So i got it to move the boxes but now they seem to just fly off the screen and the moving of the rigibody that is following the mouse is super delayed, it takes a few seconds to stop changing almost like it's slowly following the mouse instead of just equalling its position...

public class LevelController : MonoBehaviour {
    public Rigidbody2D mousePoint;

    private void FixedUpdate() {
        mousePoint.MovePosition(Camera.main.WorldToScreenPoint(Input.mousePosition));
    }

    public void Move(SpringJoint2D springJoint) {
        if (!springJoint.connectedBody) {
            Debug.Log("Moving " + springJoint);
            springJoint.connectedBody = mousePoint;
        }
    }

    public void Release(SpringJoint2D springJoint) {
        Debug.Log("Released!");
        springJoint.connectedBody = null;
    }
}

[wintry quarry]

how and where are Move and Release getting called?

also did you make the mouse Rigidbody kinematic?

[queen adder]

Hi

[obtuse oar]

through the controller on the boxes i want to be dragged:

public class BoxController : MonoBehaviour {
    public LevelController levelController;
    private SpringJoint2D springJoint;

    private void Start() {
        this.springJoint = this.GetComponentInParent<SpringJoint2D>();
    }

    private void OnMouseDrag() {
        levelController.Move(this.springJoint);
    }

    private void OnMouseUp() {
        levelController.Release(this.springJoint);
    }
}

[wintry quarry]

you're calling Move every time the mouse moves. You should just call it at the beginning

OnMouseDown

[obtuse oar]

oh it was not kinematic, though i changed that

[queen adder]

Honestly don’t know how to code

[nimble sorrel]

is there any support for displaying a key prompt as a key? for instance, rather than press the 'e' key to interract it'd show an actual e key

[wintry quarry]

what does "an actual e key" mean? An Image?

[nimble sorrel]

yes

[wintry quarry]

You'd need to build that yourself

[nimble sorrel]

gotcha, ty

[obtuse oar]

the issues shown in a clip:

[nimble sorrel]

do the boxes continuously move? or are they moving to a specific position?

[wintry quarry]

your mouse point object is in timbuktu

and it's because of this:
mousePoint.MovePosition(Camera.main.WorldToScreenPoint(Input.mousePosition));

you use WorldToScreenPoint when you wanted ScreenToWorldPoint

[tame mist]

here is the full stack trace

[wintry quarry]

right so you're spawwning a car

and calling a function on it

You know Start won't run until a frame later right?

You should be using Awake for initialization like that

[tame mist]

oh alright, I'll try that and see how it goes

[obtuse oar]

lol, whoops
I tried this but now the position isnt updating at all
mousePoint.MovePosition(Camera.main.ScreenToWorldPoint(Input.mousePosition));

[wintry quarry]

Are you using a perspective camera or orthographic?

[obtuse oar]

whatever is default upon creating a scene, idk what that is sorry

[wintry quarry]

you can always just look

[obtuse oar]

perspective

[wintry quarry]

That's your problem

perspective camera with Camera.main.ScreenToWorldPoint(Input.mousePosition) will just return the same thing as Camera.main.transform.position

use Plane.Raycast instead

or switch to an orthographic camera

[final trellis]

worlds strangest issue goes to this block of code

the function IsLookingDown is a boolean function that works completely fine (hopefully), shown by the debug statement outside of the input if statement. However, whenever I press Q to go down the if statement, the debug log inside the if statement always reports it as true. also the force is never applied as a result of this weird issue

[wintry quarry]

Your if statement is checking if you're NOT looking down

[final trellis]

yeah, its meant to only add force when isLookingDown is false

[wintry quarry]

ok so what's the issue exactly then?

it's saying "throwing: false" but there's no force being added?

[obtuse oar]

everything works, just needs a lot of smoothing and such, but now they orbit when let go...

[final trellis]

Debug.Log("throwing: " + playcam.IsLookingDown()); inside the input if statement always results in being true, looking down or not, despite Debug.Log(playcam.IsLookingDown()); outside the input if statement being completely fine

[wintry quarry]

that means the joint is not releasing

[wintry quarry]

do you have Collapse turned on in your console?

[wintry quarry]

BTW you really should be using ForceMode.Impulse or ForceMode.VelocityChange for this.

[final trellis]

collapse is turned on so its easier to see yeah

[wintry quarry]

that makes it impossible to tell what's going on then though

because you can't tell in what order things are being printed

[final trellis]

hence why the one inside the input statement has that "throwing" bit

[wintry quarry]

also there's no guarantee that the IsLookingDown() function doesn't have side effects

[wintry quarry]

I would just get rid of the one outside the if and turn off collapse

[final trellis]

IsLookingDown() is just

[wintry quarry]

that's not a good way to check that

return Vector3.Angle(transform.forward, Vector3.down) < 90;``` will do it more reliably

euler angles are a shitshow

[final trellis]

why not?

[wintry quarry]

because of this^

(-45, 0, 0) is equivalent to (315, 0, 0) which is also equivalent to (0, 90, 45)

so just reading the x part won't tell you all that much useful

[obtuse oar]

I was able to fix this by setting the .isKinematic bool to true when releasing, is this the proper way to do so? it appears that before starting the scene they are connected to this joint which makes no sense to me (ss of scene view not in play) idk if this is an issue or not tbh.

I just want them to be moved when dragging then stop completely when let go, currently they just preserve momentum but they're not orbiting lol, how can i just get them to stop?

[wintry quarry]

you have the joint there so the joint is active

there is no way to disable a joint

you can only destroy the joint or attach it to a world position or to an object

You can also just set the velocity to Vector3.zero instead of making it kinematic

the objects will maintain their velocity when you release otherwise

[final trellis]

this seems to be always reporting false, also replaced the 90 with down - lookingDownLeniancy which is 30

[wintry quarry]

are you ever actually looking down that far?

(within 30 degrees of straight down)?

also which object is this script attached to?

[polar acorn]

It'd probably be better to check if the dot product of transform.forward and Vector3.down is greater than some threshold percent like 0.9f

[wintry quarry]

checking the angle is identical to this^

just easier to understand

[final trellis]

its not 30 away from 90 its 30 in total

[wintry quarry]

I don't understand what that means

this code is checking how far away from straight down you're looking

if it's 90 it will return true whenever you are looking even slightly down

past directly horizontal

[final trellis]

down is 45, its the maximum angle you can look down in this game instead of 90

[wintry quarry]

if it's 30 it will return true only if you're looking within 30 degrees of straight down

[wintry quarry]

well don't use 30 then because that's lower than the max (and therefore impossible)

use 90 to start with

and tune it from there

[final trellis]

lookingDownLeniancy exists so you dont have to be looking exactly down for it to return true, so its a range of 30 to 45 where it counts as 'looking down'

[wintry quarry]

and I'm telling you you should be using 90 - 30 then

aka 60

not 30

30 is impossible

[final trellis]

how

i was doing 30 perfectly fine with the old eulerangle code

[wintry quarry]

return Vector3.Angle(transform.forward, Vector3.down) < (90 - lookingDownLeniancy);

[wintry quarry]

this code works differently

please listen

[final trellis]

what 'direction' is Vector3.Angle(transform.forward, Vector3.down) facing?

[wintry quarry]

I don't understand what the question means

it's calculating an angle between two different directions

• the direction you're looking
  and
• straight down

[wintry quarry]

Have you tried this code?

[hollow axle]

this vid shows an older project of mine that has a super bulky, and imo stupid, implementation of the functionality i want compared to what i currently have with the spring joint, i'm trying to configure the values in the spring join to more closely match the first part of the clip but so far i cant really get it to have the same feel, the spring joint tends to orbit the mouse too much when moving quickly. Am I approaching this problem wrong by trying to use spring joint? I was told back when i was here for advice on the implementation in the first part of the clip about half a year ago that i should try using spring joint instead for an easier implementation.

[wintry quarry]

it really depends what you're trying to do

why are you using SpringJoint in the first place?

[rotund portal]

Hey, not sure if it's the right channel to ask, but I've been struggling for the past two hours on the following problem

[obtuse oar]

i could simply teleport the boxes to the mouse position but i am using spring joint so that they instead smoothly go over to the position

[wintry quarry]

You could also use MoveTowards or SmoothDamp

[rotund portal]

I'm trying to implement a crosshair in my vr application using google cardboard, therefore I had to load an image in front of the camera in order to see the crosshair, however it goes "inside" objects rendered on the scene

my question is how can I force rendering? I didn't manage to change the shaders and i've been stuck for a while now

[hollow axle]

Already did, but it didn't work for me

[summer stump]

Remove the Visual Studio Code Editor package in Unity, they both use the Visual Studio Editor package

Does VS Code say anything about an SDK being needed?

The extension and package is up to date though.

[obtuse oar]

could you elaborate or should I do some self-study on this first?

[swift crag]

The documentation pages describe how they work and have examples

MoveTowards moves at a steady rate towards a destination

SmoothDamp behaves like a spring

[solemn anvil]

it was the fault of unity limits. I had to add
mesh.indexFormat = IndexFormat.UInt32; and it works

[tame mist]

that ended up working and i stopped using .sharedMaterial so that i could change the materials individually.
but i'm trying to figure out how to save the changes to the instanced materials so that when i load the game back up the cars have the same colors they spawned in with. is it possible to save this changed material for each car? or for each car should I save the random values I generated for the color change and then when the game loads up change the color in Awake?

[wintry quarry]

no you wouldn't save the material

you need a saved game system

you'd just save the colors

you could also use a seed value to generate the same sequence of random colors assuming you always have the same number of cars etc

[quasi rose]

Can anyone see what I have wrong here? In the inspector I have dragged in two empty GOs as the teleport locations:

    private void InputManager_OnDismountAction(object sender, System.EventArgs e)
    {
        foreach (var tpLocation in _teleportPlayerLocations)
        {
            float distanceFromTeleportLocationToJetski = Vector3.Distance(tpLocation.position, transform.position);
            if (distanceFromTeleportLocationToJetski <= TELEPORT_DISTANCE_BUFFER) // buffer is set to 20f.
            {
                Debug.Log("Dismount pressed");
            }
            else
            {
                Debug.Log("Can't dismount, not on shore! Distance away: " + distanceFromTeleportLocationToJetski);
            }
        }
    }

I'm trying to specifically go to the second log/position. It's weird because when I go to the first GO, it works, just not this second one, even though I'm within distance.

[wintry quarry]

print out TELEPORT_DISTANCE_BUFFER

also InputManager_OnDismountAction(object sender, System.EventArgs e) the EventArgs pattern is not recommended for Unity

since you're not using any parameters here you can just use System.Action as the delegate type and have no parameters.

If you do need parameters you can make a custom delegate type or simply an Action<T, T1> etc style delegate

[quasi rose]

Thanks, PB. Just realized, I had a magic number written in there as 20f earlier, then realized that was way too large, and set up the buffer variable, at 10f. My oversight, but thank you.

[quasi rose]

Thanks, I will change. Why is it not recommended for Unity though?

[wintry quarry]

creating instances of System.EventArgs generates garbage since it's a heap allocated class

this leads to GC hiccups

(same reason it's generally encouraged to avoid frequent allocations/garbage collection in general)

[quasi rose]

Ah didnt realize that's creating instances, thank you.

[quasi rose]

As an additional question, I've updated to using Action. I have an input manager script where i am doing:

    public event Action OnInteractAction;
    private void OnEnable()
    {
        _input.Player.Interact.performed += Interact_performed;
    }
// unsubbing in OnDisable()

    private void Interact_performed(InputAction.CallbackContext context)
    {
        OnInteractAction?.Invoke();
    }

Then in my PlayerController.cs class I sub to them in Start():

  InputManager.Instance.OnInteractAction += InputManager_OnInteractAction;

Should I be subbing and unsubbing as well in OnEnable() and OnDisable() in my PlayerController.cs class? I was thinking there might be some race conditions if I did that.

At the very least should I be doing OnDisable() to unsub in PlayerController.cs?

[wintry quarry]

you should always unsub in OnDisable to match every subscription in OnEnable yes

[quasi rose]

Ok even though I'm subbing in Start() within the classes that use the Input Manager set up.

I don't think I could OnEnable() across them all due to race conditions. Maybe I'm wrong.

[wintry quarry]

If subbing in Start then unsub in OnDestroy

[quasi rose]

Ah ok

That's what i was trying to determine, how to unsub properly then. Thanks!

[wintry quarry]

note when unsubbing you'll want to do this:

var im = InputManager.Instance;
if (im != null) im.OnInteractAction -= InputManager_OnInteractAction;```

this will prevent MissingReferenceException when the scene is being unloaded

[quasi rose]

Cool, thanks.

[supple wasp]

How can I make a button make infinite scenes?

[frosty hound]

What is an infinite scene and what does a button have to do with it?

[supple wasp]

I am making a 3D animation and modeling application, there is also an application of that when you create a new project, a .proj file appears.

[slender sinew]

SceneManager has a method called CreateScene that creates a new scene at runtime, which can have any name you want https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.CreateScene.html

[wintry quarry]

doesn't sounds like infinite scenes to me. Sounds like one thing.

[supple wasp]

Look at the photos

[rich adder]

huh how's it related to infinite scene?

[teal viper]

I think there's a language barrier. Maybe try using Google translate to convey your thoughts...

[wintry quarry]

Nothing infinite here. Do you mean how to show a file selector?

[frosty hound]

I suspect they actually mean just creating a new scene/project. As in, each time you press [new] it does so ... hence infinite.

[rich adder]

xD someone needs to learn about system.io

[supple wasp]

It's like I was going to create a Minecraft world but in unity within the game

[rich adder]

or maybe make virtual folders in the unity build

sounds more like you need to learn about saving data / files instead of scenes

[supple wasp]

More or less so

[rich adder]

start serializing some data in a file , go from there

json is easy to start with

[marble sapphire]

well

does anyone know why this wouldn't shoot a Ray?

I tried debugging

but it says it's unreachable

[north kiln]

Your IDE looks suspiciously underhighlighted, are you getting error highlighting and autocomplete?

[marble sapphire]

well, I tried re-downloading

it doesn't seem to change anything much

[north kiln]

I take that as a no then. The configuration steps are here !ide

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• Other/None

[north kiln]

and yes, if you put a log after a return statement, how can it be reached? You just returned, you exited the function

[summer stump]

Fix the debug as vertx said, and put a debug before the tag check too. You want to know how far it gets

[marble sapphire]

I'll try that. Thanks.

[rich adder]

yup configured IDE would def show you dark gray for code underneath return statement

[marble sapphire]

OK Now it's kinda going crazy

Whup My mistake. I made the Ray linger for 100f

[north kiln]

If you still have not configured your IDE, that's the first thing you should do

[marble sapphire]

well

I *did * update the VS

but the highlighting didn't change.

[rich adder]

did you read the steps at all?

[marble sapphire]

I read em all

[rich adder]

update is like the last step

[marble sapphire]

yeah

but I already installed it manually

the proper way

2 times

[rich adder]

so what about the Unity Workload in VS Installer

[north kiln]

The workload, the settings in Unity's External Tools preferences

[marble sapphire]

yea

already set to unity

[rich adder]

assuming you actually did all the steps, whats left is try regen project files or check the solution explorer if the solution needs rebuild

[north kiln]

set to Unity
What is this referring to

[frozen dagger]

Is there any way to make animated objects play when time.scale = 0?

I’m asking for second time

[queen adder]

New to reading data from json files, experimenting with this tutorial in the first screenshot. I can't tell why my code (second screenshot) is throwing a nullreference error on the for loop.

[frozen dagger]

I want to make pause menu like here, but the only way to pause game what I know is making time scale = 0

[wintry quarry]

Have them use unscaled time

[frozen dagger]

How?

Is it an option in animation/animation controller or where? Or I need to script it

[rich adder]

ur list is null

[wintry quarry]

Not enough info here but either the array or the wrapper object itself is null

Likely the json data isn't correct for that object

[wintry quarry]

Yes it's an option on the animator or the state machine

Don't remember which

[frozen dagger]

Ok I’ll check, thank you so much!

[queen adder]

I suspect its because the array inside the list class isnt declared as an instance, but the tutorial code didnt do that, and it worked for them

not sure where mine differs

[wintry quarry]

I told you why

Your json is incorrect likely

[queen adder]

I had a json syntax error before and fixed it. What about the json file would be incorrect?

[wintry quarry]

The shape of the data

[wintry quarry]

It doesn't match the object

[wintry quarry]

Yep the name is wrong

It's not called "weapon" in your class

It's called "lazerWeapon"

[queen adder]

now that part they never said had to match

nice

[wintry quarry]

Of course it has to match

All the field names must match

How else would it know which data to put where?

[rich adder]

thats the point of mapping an object 😛

granted with something like json.net you can create custom names and map them accordingly but thats another story

[queen adder]

my brain is closer to our ape ancestors than most please bear with me

[rich adder]

all ur doing is matching names

1:1

[queen adder]

but due to this revelation, I must now restructure how my data flows

which i've been doing all day

fun

[rich adder]

the rest look fine, all ur changing is the main object

weapon

[queen adder]

I have two weapon types, more like categories: Lazer and Physical. Lazer weapons just use a ray to fire, so there are a bunch of different numbers that go into making them unique from each other. Physical weapons spawn a projectile, such as a grenade launcher, rocket launcher, etc. Their only differing stat is reload time, the other stats are on the object they spawn.

I'm trying to group the stats of the two different weapon types into one location, which i can stream from in a weapon_pickup_manager, which can forward the data to the singular player_weapon script that handles the weapon behavior

Seems I'll need two different json files for each weapon type

despite my best efforts to put them in one place

[rich adder]

your namings is very confusing not for nothin

[queen adder]

Could rename them Raycast and Projectile weapons

but regardless, outcome is the same

[rich adder]

weapon_pickup_manager has stats?

anyway you can totally put them in one file, don't see the problem

[queen adder]

using System.Collections.Generic;
using Unity.VisualScripting.FullSerializer;
using UnityEditor;
using UnityEngine;

public class Weapon_Pickup_Manager : MonoBehaviour

        {
            print(lazerWeaponList.lazerWeapon[i].name);
        }
    }

not finished yet obviously

[rich adder]

I wouldn't nest regular objects in a MonoBehaviour

messy

[queen adder]

thats what the tutorial did

i just blindly followed along

I do as the crystal guides

[rich adder]

bad tutorial

[queen adder]

very

[rich adder]

should start at least naming things that match lol

[eternal needle]

This is cursed. Why is there a class that says lazer weapon list, then it holds an array and that's its only purpose?

[queen adder]

THE TUTORIAL

Blame the tutorial

i give up, i will sleep and resume this dumbassery tomorrow

Thanks for the help

[eternal needle]

Tutorials should give you a sense more of what exists and what is possible, this wont be too fun to scale up later

[queen adder]

figures

First time utilizing json files though, hopefully more success tomorrow

[rich adder]

start small, serialize one object

work your way to arrays

nested objects are tricky

and name things properly lol

[queen adder]

names are the most difficult part

[rich adder]

public class Wepons
{
    public List<Lazors> LazorWeps { get; set; }
    public List<Projectile> ProjectileWeps { get; set; } 
}
```idk

as long as it matches the json lol use w/e

[eternal needle]

You dont need to short form for names, but you could take a look at the Microsoft convention on how to name things. Using underscores in the middle of names is like a python style thing or I think enums in java

Not really c# convention though

[rich adder]

yes drop that habit lol

ugly af

[fierce shuttle]

Ive only seen underscores used in C# for const and local variables that start with "m_" (though I personally dislike the latter convention, a lot of Unitys internal scripts will use it alot, and it just looks ugly but I get its purpose)

[rich adder]

my const usually start with c_ 🥵

[eternal needle]

That m_ convention is mainly just old c++ stuff, so makes sense its old internal unity code

[rich bluff]

those are members not locals

[fierce shuttle]

Ah are those terms different? I thought they meant local to the class, as in they cannot be accessed outside of the class they were declared in

[halcyon steppe]

so i'm trying to make a holdable system and i can't find a way to disable myRB (which is a rigidbody)

if (Input.GetKey(holdButton) | Input.GetButton("A")) {
                myRB.enabled = false;
                transform.SetParent(holdingGameObject.transform, false);
            } else {
                myRB.enabled = true;
                transform.SetParent(null);
            }

[rich bluff]

in c# local means inside a method

[fierce shuttle]

Ah I see, thanks for the clarification

[fierce shuttle]

AFAIK, you cant directly toggle a rigidbody with .enabled, you could try freezing all the constraints instead and .Sleep() it, or enable .isKinematic so its not affected by physics

[eternal needle]

you'll want to make it kinematic, sleep will only work if it doesnt get hit by anything and does not move. Moving the transform will wake it up

[fierce shuttle]

Oh, interesting

[rich bluff]

you can also switch layer/ set ignore collisions

[candid eagle]

Hey everyone, I'm running into a bit of a brain ache right now, I was hoping someone could point me to the right direction, basically, I want to generate a terrain procedurally, by creating the tile meshes through code and placing them with perlin noise for height variations, my issue is I need my tile to get a distinct value based on it's surrounding tiles heights so it can be curved accordingly, I have a function that is highly inefficient and that doesn't work in cases where the height of the terrain varies to much, my question is, based on the surrounding tiles, how can I get a distinct value to work with to identify which configuration my tile should have? here are some images to demonstrate what I have so far, thank you in advance :

[rich bluff]

do you know about marching cubes?

[candid eagle]

a type of voxel right?

I also should have pointed out that the curve of the tiles are configured via an animationCurve which gives me more controle over the slope

[rich bluff]

no, its an algorithm

it builds the mesh from premade pieces based on an index assigned to each voxel

its efficient because it does lookup by that index with direct array access

[candid eagle]

oh, I wasn't aware of that, I'll look it up thank you! can I still use it if I want controle over curves, like this ? :

also, how efficient would that be if I want tiles with high resolution, let's say 64x64?

Thank you anyway I'll look it up, I think sebastian lague has a video on it. have a great day!

[mighty moat]

Can I set multiple ints to 0 ? like "heat, power, cornFlakes, flem=0;"

[rich bluff]

heat = power = cornFlakes = flem=0;

[mighty moat]

You legend, TYVM (:

[idle sleet]

Sorry if this is a simple question. The world is measured in meters and I’m trying to move my plane in m/s where the player can adjust their speed 0-10 to speed up or slow down how might I do this

[teal viper]

In many different ways. What do you have so far?

[idle sleet]

Currently I’ve just getting the position of the plane and moving it by 1 so say we’re moving forward by 1 meter per second but I don’t think that makes sense or is correct since my plane will move so slowly

[teal viper]

Share some code.
Instead of 1 you want to use some variable that changes value depending on what speed you want to have.

[idle sleet]

Currently I have float speed = 1.0f // move 1 meter per second? if (Input.GetKey(KeyCode.UpArrow)){ transform.position += Vector3.forward * speed * Time.deltaTime; }

[teal viper]

Great. So you just need to assign a different(changing) value to speed

[idle sleet]

Ah ok so that’s correct? Think it’s gonna be quite slow though for the plane

[teal viper]

You can assign whatever value you want🤷‍♂️

[valid leaf]

can I suggest using transform.Translate(Vector3.forward * speed * Time.deltaTime); it's much better than just doing position += something.

and yes, 1m/s is quite slow... for reference it's 3.6km/h or ~2.2mph, which is about your average walking speed

[idle sleet]

Alright thank you both!

[teal viper]

Why?

[swift crag]

transform.position += transform.forward * Time.deltaTime * speed;
transform.Translate(Vector3.forward * Time.deltaTime * speed);

these will be equivalent

I don't find one that much nicer to use than the other.

[valid leaf]

They're both the same, unless the transform rotates

[swift crag]

the important difference is that your code doesn't care about the rotation of your transform

it'll always move in the +Z direction, no matter how the transform is rotated

using transform.forward instead of Vector3.forward fixes this

as does using the transform.Translate method

[teal viper]

I just think it's important to explain the reason when you give advice to beginners.

[swift crag]

I wouldn't say it's "much better", yes

[valid leaf]

Moves the transform in the direction and distance of translation.

If relativeTo is left out or set to Space.Self the movement is applied relative to the transform's local axes. (the x, y and z axes shown when selecting the object inside the Scene View.) If relativeTo is Space.World the movement is applied relative to the world coordinate system.

[swift crag]

transform.Translate interprets its argument as a local direction, rather than a world direction

hence the difference

transform.position += Vector3.forward; // always goes in the world's forward direction
transform.Translate(Vector3.forward); // always goes in *your* forward direction
transform.position += transform.forward; // always goes in *your* forward direction

and then there's the funny fourth wrong option

transform.Translate(transform.forward); // ???

[teal viper]

I mean, explain why "it's much better"

[timber tide]

transform.position += transform.forward;```
I don't think I've used anything but this one

still not too sure if I should bother converting a lot of projectile logic over to rbs

lose out on a lot of positional functions I use otherwise

[valid leaf]

it might not be that much better as a single occurrence, or in the given example, more... a syntax, (practically non-existent) performance difference and personal experience in moving things in games, there tends to be parenting, unparenting, etc. happening and using translate makes the movement stay more consistent

[swift crag]

This is nearly word salad.

transform.Translate defaults to local space. That's about it.

If you have a local-space vector, then it makes sense to use it

the alternative being transform.position += transform.TransformVector(vec);

transform.Translate(vec); is easier to understand in that situation

[polar acorn]

Also translate has a parameter you can pass in to make it be world space instead of you'd rather do that

Oh I see that was brought up already

Sorry I just woke up I should scroll more

I would say that because of that parameter alone, translate is better than adding to position directly, since it lets you more rapidly switch between modes if you need to refactor something or for debugging purposes, but thats a pretty niche situation. Under the hood it's all addition anyways, so there's no performance benefit or anything

[dry tendon]

does anyone know how could i specify the long of the vibration?

cause what exacly does that method rn? how many dime it spends vibrating?

[rich adder]

specifiy it how ?

put your own nmbers

[languid spire]

Vibrate does not take any parameters so I guess the duration is down to the device itself

[dry tendon]

yeah, the duration i think

[dry tendon]

i cant pass it any value...

and i don't know how to choose the duration length...

[languid spire]

you cannot

[timber hatch]

(sry not code i' did not find specific channel) we are a team of developper and beginner on unity, we want to collaborate with github. The original project load the textures but when we dl it, its this redish texture that appears, we have no clue... 🙂 thx

[dry tendon]

so... how could i make it bigger or smaller?

like the length the vibration plays

[languid spire]

what about 'can not' do you not understand?

[dry tendon]

yeah, i understand it, but imagine i want the phone to vibrate for 5 secs...

[dry tendon]

how could i do that?

is it possible?

[languid spire]

NO!!!!!!!!!!!!

[dry tendon]

Is impossible to do that in unity? hmm... is the first time that unity put me a limit on something hehe <:

[wintry quarry]

Not sure for a phone but https://docs.unity3d.com/Packages/com.unity.inputsystem@1.7/api/UnityEngine.InputSystem.XR.Haptics.SendHapticImpulseCommand.html?q=Haptic

Pretty sure phones don't let you do extended rumbles though

Just little vibrations

[languid spire]

I mean you can do, at least on Android by calling the OS directly but that is well outside of this scope

[hexed terrace]

Do a coroutine that calls it multiple times until the time limit has ended

[dry tendon]

ohh, thanks, i'll look for it hehe

[grizzled mountain]

Hey everyone, I am having a problem with my player movement in my game and I just can’t figure it out. My game has a top down Isometric camera. For my movement, I want to control the direction of the movement via W, A, S, D while controlling the rotation via Mouse. So the player rotates where I move the mouse without changing the direction the players moves. This has been a pain to implement. My Blend tree has 8 way animations that are controlled by the parameters velocity.x and velocity.z. The problem is I have no idea how to implement the rotation. Because right now if I for example press w to walk up, but look to the left. The forward animation is being played since the velocity is set to forward. But instead the player should move to the top while the right strafe animation is playing since I am looking to the left. I have no idea how to implement the rotation into my animation controller while still using velocity too. Any help would be appreciated:)
PS: As an example of what the final movement should look like you can look at the game soulstone survivors.

[swift crag]

The animation you play should depend on the local direction of movement.

Vector3 worldMove = Vector3.forward;
Vector3 localMove = transform.InverseTransformDirection(worldMove);

[grizzled mountain]

You mean instead of velocity?

[swift crag]

ah, I should say velocity

since you care about not only the direction, but also how fast you're going

Vector3 worldMove = Vector3.forward;
Vector3 localMove = transform.InverseTransformVector(worldMove);

Suppose the player is facing to the right

localMove will wind up being a vector that points to the left

because the player is moving in the world forward direction and facing the world right direction

[solemn fractal]

Hey guys. What is another good way to rotate around something other than using this method, that is working for me but it is also rotating the transform rotation of the object it self, and I dont want that. cs transform.RotateAround(_player.transform.position, Vector3.forward , 30 * Time.deltaTime); Tried so many other things and nothing seems to work sadly. Imagine I have 2 objects.. 2 circle 2d and I want one to orbit the other without rotating itself

[swift crag]

so, from the player's perspective, their movement is in the left direction

[swift crag]

I don't understand your problem. Are you saying that you don't want the child object to care about how its parent is rotated?

Oh

I see.

You want the child to move without changing the direction it's facing.

[grizzled mountain]

So just so I understand correctly, I should base my parameters based on localMove and not solely on velocity?

[swift crag]

Yes. Your problem is that the player's velocity is in world-space.

So it's the direction + speed you're moving in the world

You need a velocity in local-space

which will be the direction + speed you're moving from your point of view

[grizzled mountain]

Thanks for the help I will try this once I am home, can I contact you in case I run into problems?:)

[swift crag]

just ask here again

you can ping me

[grizzled mountain]

Will do thank you!

[solemn fractal]

No

[solemn fractal]

I have 2 separated objects, they are not child of each other or something like that

1 is the player the other is the boss. and everytime the player goes nearby the boss or far away I set that the boss will react accordinly and it works.. but I also want to add another movement for the boss.. not only going close or further from the player but also rotate around the player

[swift crag]

One option would be to just calculate a new position and go to it directly.

Vector3 position = transform.position;
Vector3 parentPosition = transform.parent.position;

Vector3 offset = position - parentPosition;
Quaternion rot = Quaternion.AngleAxis(30 * Time.deltaTime * speed, Vector3.forward);

Vector3 newOffset = rot * offset;

transform.position = parentPosition + newOffset;

[solemn fractal]

It works, but it is also rotating the boss rotation transform

[swift crag]

Ah. That should not be happening.

[solemn fractal]

but it is using cs transform.RotateAround(_player.transform.position, Vector3.forward , 30 * Time.deltaTime);

[swift crag]

or maybe I am misunderstanding.

[solemn fractal]

and if I try to fix the transoform.localrotation as quaternery,.iodentity it stops working

[swift crag]

So the boss is orbiting the player.

And you want the boss to not get rotated.

[solemn fractal]

yes the boss rotation should be fixed and the object boss should go around the player

[tepid cobalt]

Could anyone help out with Pool Manager related questions?

[swift crag]

ask your question.

[solemn fractal]

    private void BossMovement() {

        float dist = Vector3.Distance(_player.transform.position, transform.position);

        Vector3 MoveDirection = (_player.transform.position - transform.position).normalized;
        Vector3 MoveDirection2 = (_player.transform.position + transform.position).normalized;

        if (dist < 20)
        {
            _rb.velocity = MoveDirection2 * _speed;
            //transform.RotateAround(_player.transform.position, Vector3.forward , 30 * Time.deltaTime);
            
        } else if(dist > 35){

            _rb.velocity = MoveDirection * _speed; 
        }

    }```

[swift crag]

here's an idea: make an empty object orbit the player

then make the boss move towards that empty object

[solemn fractal]

that is what I have now and works.. but if I add the line that is commented it rotates around but also rotate around itself

[swift crag]

You're trying to modify the transform of an object that also has a rigidbody on it.

That will cause problems.

[swift crag]

This would avoid that!

The boss would just try to move on top of that empty object.

[tepid cobalt]

This is my current loop:

Player spawns (Has stock pool of 1 item)
Player breaks into pieces. (pool is cleared, and reutrned to 1 default)

Im having issue geting my playerid attaching to all the seperate pooled objects that belong to me. Is it best to serve the ID from the PoolManager as a global variable?

[solemn fractal]

will try that thank you

[swift crag]

alternatively, just have the boss calculate which direction would make them orbit around the player.

This would be a good place to use Vector3.Cross, actually

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

A: vector pointing at the player
B: vector pointing into the screen
Result: vector that makes you orbit counter-clockwise around the player

[swift crag]

i don't understand how an object pool is relevant here

[tepid cobalt]

There is going to be lots of people doing this

all shattering, collecting fragments

dropping their collected fragments

[swift crag]

Player spawns (Has stock pool of 1 item)
Player breaks into pieces. (pool is cleared, and reutrned to 1 default)

This does not make sense to me. Is this just a collection of fragments that the player is holding?

Object pooling is used to avoid creating and destroying lots of objects by reusing them

[tepid cobalt]

So if the player has collected... lets say 3000 fragments, its going to be a big drop. I assume you would collect them in each players pool because you can just reuse them for the drops to save instancing new objects

[swift crag]

I would just have one big object pool for fragments.

When the player breaks, it spawns a bunch of fragments

It would ask the object pool to give it these fragments

and then the fragments are collected, they'd go back into the object pool

[swift crag]

If you need to attach any data to the fragments, do it at this point.

also, I would consider grouping these fragments together :p

[tepid cobalt]

ye i have them under 1 parent prefab

[swift crag]

I am reminder of UT3's Greed gamemode

you collect skulls from killed players

[tepid cobalt]

Yeh it looks fun eh?

[swift crag]

5 skulls will turn into a larger skull instead of dropping as 5 small skulls

so you don't get a huge pile of objects

[tepid cobalt]

Hopefully i can pull it off, ur a legend thanks for your input

[swift crag]

Even if you want to have lots of physics objects everywhere, 3000 sounds like a ~lot~

[pseudo sable]

similar approach in games like vampire survivors etc, xp gems get grouped at some point

[tepid cobalt]

Is it the rigid body collisions that cost alot of performance? I can wack them on a seperate layer as a sort of "entity?"?

[swift crag]

That would be expensive, yes.

it would also probably be unstable

with objects clipping into each other and going flying

[tepid cobalt]

Ive had it up to about 1200 so far wit RTX

then it burns

[swift crag]

I'd make fragments of size 1, 5, 20, 100, 500, something like that

[tepid cobalt]

Voxel size?

[swift crag]

value -- whatever you're counting here

[tepid cobalt]

ah true

[swift crag]

so a 500 fragment would give you 500...fragment points, or whatever

to decide what to spawn, pick the largest possible fragment until you're down to 0

[tepid cobalt]

Yeh and just make that piece bigger

[swift crag]

maybe add some randomness too

[tepid cobalt]

or something

[swift crag]

so there's a chance to pick a smaller one anyway

[pseudo sable]

bigger/different colour is usually a good approach for visual clarity that it's worth more

[tepid cobalt]

I was going to add gravitational pull so you dont need to walk close

[tepid cobalt]

Yeh i like the idea

[gusty gyro]

is this possible like rigging the arm of that charcter within the border using mouse input?

[swift crag]

you could use visual effects to make it look like the big fragments are shattering into many small pieces as they fly towards you

might make it more fun

[swift crag]

This looks like an inverse kinematics problem.

[tepid cobalt]

You scale up in size the more you eat, I was going to make it once you got to a certain scale, little blocks only "chip" blocks of you off and can pick them up

[swift crag]

figuring out how to rotate the joints so that the gripper is at the desired point

[tepid cobalt]

While you slowly roam around the map like a mamoth

[swift crag]

I forget if unity has that built in for 2D arms.

[pseudo sable]

#🏃┃animation channel might be a shout

[gusty gyro]

but its possible? do you have any recommendation if its possible?

[swift crag]

https://docs.unity3d.com/Packages/com.unity.2d.ik@3.0/manual/index.html

This looks relevant.

Keeping the arm inside the border is the easy part. You'd just clamp the mouse position.

Probably like this

[gusty gyro]

Thanks ill look on it

[tepid cobalt]

why does 2d dev look harder than 3d

or am i just simple

[swift crag]

Vector3 targetPos = // get a desired position somehow
Vector3 delta = targetPos - armHolder.transform.position;
delta = Vector3.ClampMagnitude(delta, 100);
targetPos = armHolder.transform.position + delta;

this would limit the arm to reaching 100 meters

might want a smaller number :p

[gusty gyro]

oooohhhh okay!!! thanksss

[sand glen]

its not

[hexed terrace]

there's very little difference in 2d/ 3d dev..

[tepid cobalt]

thus why it looks hard because im struggling with 3d xD

[tepid cobalt]

So the first block of fragments the players get go into "the" pool now.

Players are shifted into the player pool to reuse their objects for respawning.

Is that what you mean?

The cube fractures, the assigned fracturedobject is activated(leaving fractures in the world), and then a new deactivated fracture propagates in the pool for the respawned player to drop again.

[solemn fractal]

Hmm.. ok interesting. i will check this out. the way you said to do worked great for me.. create an empty object that will make all the movement and its a separate object not parent not child from the boss and the boss just follow it..

[solemn fractal]

but maybe with this .cross would work without the need of doing the empty object

will need to try

hi can anybody help me ou with NavMesh Components ?

[rich adder]

https://dontasktoask.com

[stable portal]

i need help with NavMesh Components i have it set up on my enemy but it does not work im going to send video of the problem now.

[charred fossil]

Hi I am having a really hard time fixing a bug in my code fr a 3D FPS shooter and was wondering if anyone is free to help out?

[silk night]

Nav Mesh Agent on Enemy and NavMesh Surface on your floor?

[silk night]

#💻┃code-beginner message

[stable portal]

yes

[silk night]

Ok then ill wait for the video

[rich adder]

what are we supposed to look at

whats supposed to happen

btw shouldnt use rigidbody on navmesh agent unless its like locked on constraints

also you have a script error you should fix

[stable portal]

the enemy should chase the player when the player is in sight range and attack the player when in attack range

[rich adder]

well we're gonna have to look at the script

also like I said if that error is part of this script then it can cause weird issues too

[stable portal]

it is not part of the script

https://paste.ofcode.org/DWUGeUUpfHPxebMaWxFKDk

[stable portal]

heres the code

[charred fossil]

Hi everyone, I am new to Unity and would really appreciate some help with my code. I am having an issue where, when I run my code, even if the player starts on the ground it is teleported up to a height of 2.8 every time I move at all. This is resulting in my grounded code not working and so I can't implement any forms of ground checks for anything in the future. Any help would be much appreciated as I have been working from youtube tutorials from many different people and have been stiching parts together.

[languid spire]

It might help if you posted your !code

Tried to understand how to put it into the code.. but it is not working cs _rb.velocity = Vector3.Cross(_player.transform.position ,transform.position) * _speed;surely something is wrong.

[swift crag]

you're crossing two positions. that doesn't really make sense

[rich adder]

collapse the other debugs

[swift crag]

you want to cross two directions

[rich adder]

you have another error @stable portal

[solemn fractal]

ahh ok not positions..

[swift crag]

The first direction should be the vector pointing towards the player.
The second direction should be pointing into or out of the screen

[solemn fractal]

Got it will test now

[swift crag]

The second direction will decide whether it's clockwise or counterclockwise

Also, make sure to normalize the result

otherwise the enemy will move faster when they're further away!

[merry spade]

When i try to raycast to the left and to the right of my character(currently the raycastdirection is Vector3.right and Vector3.left) the raycast turns with the object but it should the direction shouldnt move when the character rotates how can i achieve this?

[stable portal]

I have only those 2

[rich adder]

you should still fix

[feral palm]

can someone help me. when i launch unity on my laptopwith github it wont load . it will give me a error report screen

[swift crag]

Ask about this in #💻┃unity-talk . This isn't a code problem.

also show us what this error is.

[feral palm]

ok

[grizzled mountain]

hey, could you give me an example on how I would calculate the velocity x and zz with localmove?

[swift crag]

once you get localMove, just read its x and z values

[feral palm]

sent it in the channel

[swift crag]

transform.InverseTransformVector gives you a local-space vector that matches the provided world-space vector

So, as an example

transform.localPosition = transform.parent.InverseTransformPosition(transform.position);

This does nothing

It turns its world position into a local position from its parent's POV, then sets its local position to that.

transform.position = transform.parent.TransformPosition(transform.localPosition);

same deal

(in fact, I'm pretty sure this is roughly how Unity decides what the world position of a parented transform is!)

(Inverse)TransformPosition is used for a position. The result depends on your transform's own position

(Inverse)TransformVector is used for a vector. Your own position doesn't matter.

[solemn fractal]

Done like that and it is working. Thank you my friend. ```cs
float dist = Vector3.Distance(_player.transform.position, transform.position);

    Vector3 MoveDirection = (_player.transform.position - transform.position).normalized;

    if (dist < 30)
    {

        _rb.velocity = Vector3.Cross(Vector3.forward, MoveDirection).normalized * _speed;
            
    } else if(dist > 35){

        _rb.velocity = MoveDirection * _speed; 
    }
}```

[swift crag]

and (Inverse)TransformDirection is used for a direction. Your scale doesn't matter.

[swift crag]

nice 👍

Hey, guys! I have a question. When I am opening Pause Menu game object on my game and go to my options scene and then I want to get back to my pause menu I don't see my pause menu screen there opened like I had it. I know that everytime another scene loads everything included the previous scene were destroyed. So, what I want to know is how to use DontDestroyOnLoad() I have never used that before and I don't know what to do?

[gaunt ice]

is it your code?

[digital latch]

nope
it's an assest

[gaunt ice]

better to contact the creater, the error says there is no PopupShaderProperty method in class MaterialEditor

[digital latch]

ok

[swift crag]

it appears in https://docs.unity3d.com/Packages/com.unity.render-pipelines.core@13.1/api/UnityEditor.Rendering.MaterialEditorExtension.html

Perhaps the asset is designed for URP/HDRP, and you're using the built-in render pipeline

[gaunt ice]

the problem is not whether you use DDOL , instead when you return the game option scene from game play and reload the game play scene (idk how you call it btw) and there is no memory on game play scene before you load the option scene, and game play scene cant restore the state.

[grizzled mountain]

// Use localMove to directly set velocity parameters
float targetVelocityX = localMove.x * targetSpeed;
float targetVelocityZ = localMove.z * targetSpeed;

        // Smoothly adjust current velocities to target velocities
        velocityX = Mathf.MoveTowards(velocityX, targetVelocityX, Time.deltaTime * SpeedChangeRate);
        velocityZ = Mathf.MoveTowards(velocityZ, targetVelocityZ, Time.deltaTime * SpeedChangeRate);

if (_hasAnimator)
{
_animator.SetFloat("velocity.x", velocityX);
_animator.SetFloat("velocity.z", velocityZ);
}

This works like it is intended too except that for example my forward run is at x= 0 and z= 10 (10 is my movespeed) but the max Z velocity I get when pressing W is 7. The rotation works though tank you

[swift crag]

what's with targetSpeed?

show me the entire script

[grizzled mountain]

private void Move()
        {
            // Set target speed based on move speed, sprint speed, and if sprint is pressed
            float targetSpeed = _input.sprint ? SprintSpeed : MoveSpeed;

            // A simplistic acceleration and deceleration designed to be easy to remove, replace, or iterate upon

            // Note: Vector2's == operator uses approximation so is not floating point error-prone and is cheaper than magnitude
            // If there is no input, set the target speed to 0
            if (_input.move == Vector2.zero) targetSpeed = 0.0f;

            // Calculate the move direction based on input
            Vector3 moveDirection = new Vector3(_input.move.x, 0.0f, _input.move.y);

            // Correct input direction based on camera's 45° rotation on the Y-axis
            moveDirection = Quaternion.Euler(45, 45, 0) * moveDirection;

            // Normalize the corrected input direction
            moveDirection.Normalize();

            //Vector3 worldMove = transform.TransformVector(moveDirection);
            Vector3 localMove = transform.InverseTransformVector(moveDirection);
// Use localMove to directly set velocity parameters

thx

[pulsar lodge]

Hey guys, I am brand new to using unity and I am stuck trying to get a scene change with a trigger on a box collider 2d. I'll include a screenshot of my script and my object settings. Whenever i try to walk into an object it is acting like a rigid body and I am not sure why. I attached the object's script and my player controller's isWalkable script

[swift crag]

do you mean it acts like an obstacle?

a rigidbody is just something that can be moved around by physics

[pulsar lodge]

yeah, i Think it is getting caught by my isWalkable logic

which should be looking at the layer "SolidObjects"

[swift crag]

You'll want to do two things, I think

One: Only look for objects on the appropriate layers

Two: Ignore triggers

I'm actually a bit unsure on the second point -- the Physics2D.queriesHitTriggers documentation says it's for raycasts

I don't do very much 2D

but maybe that's just badly worded

I see that you're passing solidObjectsLayer to the overlap method

What is that?

[pulsar lodge]

should specify which layer the isMovable looks at

the SceneChange object is not in that layer so I'm not sure why its getting caught by that

[rich adder]

hey unrelated to your issue but look at what IDE is suggesting 🙂

[swift crag]

Perhaps it's not! You should check what you're actually hitting.

Try logging the collider you're finding

[pulsar lodge]

Well, i got it to not collide by changing the layer from default to creating a new one, but it still is not triggering.

[pulsar lodge]

I just chaged it to other.CompareTag("Player");

[rich adder]

did you try what they suggested ? with logging what you hit

[pulsar lodge]

I'll see if i can figure out how to do that haha

[rich adder]

well. other is what you hit

the code editor gives you a bunch of stuff when you do other.

[pulsar lodge]

I thought other was the player in this instance

[rich adder]

thats why you debug

so you are certain

eg
Debug.Log(other.name);

Outside of the Tag but inside the trigger

Trigger Enter is good log but not very useful 😉

[pulsar lodge]

So like this?

location wise?

[summer stump]

That's fine. You could combine the two logs if you want though
Debug.Log($"Trigger entered by {other.name}");

[pulsar lodge]

Hmm, even with that in there, nothing prints to the debug log, it is like this is not even executing.

[rich adder]

oh wait you wanna log the Physics overlap not this

if ur having problem with iswalkable

[pulsar lodge]

Well even when i comment that out, it still doesnt work, i thought that might have been the cause.

[rich adder]

what does isWalkable do again?

for movement right

[pulsar lodge]

isWalkable basically is checking if a tile is in the SolidObject layer, if it is dont allow to walk

[sage mirage]

Hey, guys! I have an error where it says Stack Overflow Exception: The requested operation caused a stack overflow. Can you guys explain to me first of all how to handle that error and secondly why that's happening when I am using DontDestroyOnLoad() on my other method where I want to load another scene?

Here is the code:
https://paste.mod.gg/xflekmslyaxp/0

[rich adder]

use Collider2D[] results and print out what you hit

but if trigger is causing issue and is not in solidObjectslayer , it shouldn't be a problem

is good to double check anyway what it is you're hitting, its an array so you just make for/foreach loop to print results of each col

[summer stump]

Show the code.

[polar acorn]

You went infinite somewhere. Show code

[sage mirage]

@polar acorn @summer stump Here!

[pulsar lodge]

I feel like such a novice 🙁 I'll attempt to get that logged lol

[rotund falcon]

I want to make a system that generates things over 18 tiles. If the generator wants to generate something one tile higher than 18, how can i say him that its 1 and not 19?

[gaunt ice]

modulo operation

[summer stump]

What is the point of having DontDestroyOnLoad be a function that calls DontDestroyOnLoad?
Looks like you call it twice for the pause menu too. I need to do something, but I can look more soon

[polar acorn]

DontDestroyOnLoad calls DontDestroyOnLoad which calls DontDestroyOnLoad which calls DontDestroyOnLoad which calls DontDestroyOnLoad which calls DontDestroyOnLoad which calls DontDestroyOnLoad

[summer stump]

Ahhh yeah of course. It is recursive.
That is a danger of naming your function the same as a Unity function. Never really a good idea to do that

[sage mirage]

I am using it first time but I don't call it twice bro??

[summer stump]

Yes you do

[summer stump]

LoadOptionsScene()
And
GoBackButton()

And BOTH of those start a recursive loop infinitely long till crash

Don't name your functions the same as Unity functions

[rich adder]

you would need to use the contactfilter2d version

[gaunt ice]

i think you likely get an DDOL must be called on root gameobject warning from what you had said

[polar acorn]

No, what they got was a quantum singularity that threatens to destroy physics as we know it, thankfully the compiler caught it and closed the program

[sage mirage]

Wait, yes I am calling it but not for that purpose you say, I was thinking to make when I am pausing my game and load the other scene to don't destroy pause menu screen and when clicking back button to go back to my main scene to dont destroy it as well. So, in this case of mine the pause menu screen was destroyed twice.

[gaunt ice]

this

[polar acorn]

DontDestroyOnLoad is something that you call one time to mark the object as a DDOL.

You don't call it every time a scene changes

once it's a DDOL it's a DDOL forever until you manually destroy it

[sage mirage]

Oh, ok!

[calm osprey]

anyone knows if referencing a gameobject through a script using the "findwithtag" thingy work if the object will only get instantiated mid-game?
considering I type something like

{
enemy = GameObject.FindWithTag("Enemy");
}```

[polar acorn]

Does an object with that tag exist when this object is created

[summer stump]

Won't work if the start is called before instantiate

[gaunt ice]

instantiate will return the object that newly created

[calm osprey]

so I need to put it in update?

[summer stump]

No. Do this
#💻┃code-beginner message

Just capture the reference

[stable portal]

i fixed it now i have no errors but its still not working

[rich adder]

check other logs make sure you don't have 2 conflicthing logics (eg waiting / chasing)

[gaunt ice]

what you need to do is

SomeType t=Instantiate(the t);

[rich adder]

is better to use statemachine instead of bools for that reason @stable portal

[sage mirage]

So, I understood that but how actually can I handle that error, I just removed that two lines of code of my DontDestroyOnLoad() .

[stable portal]

i dont realy know whats that

[summer stump]

Just make the pauseMenu put ITSELF in DDOL in its awake

[polar acorn]

Don't make a function that calls itself which calls itself which calls itself which calls itself which calls itself which calls itself which calls itself which calls itself which--

[rich adder]

    [SerializeField] private ContactFilter2D contactFilter2D;
    private bool CanMove(Vector3 targetPos)
    {
        Collider2D[] cols = new Collider2D[10]; // start with 10 results (expands itself)
        var hits = Physics2D.OverlapCircle(targetPos, 12, contactFilter2D, cols);
        if (hits > 0)
        {
            for (int i = 0; i < hits; i++)
            {
                Debug.Log(cols[i].name);
            }
            return false;
        }
        return true;
    }```
Something like this should help you get started

[stable portal]

i followed this tutorial https://www.youtube.com/watch?v=UjkSFoLxesw&t=287s

[rich adder]

for example an Enum can be used a simple state machine

[sage mirage]

In its awake? What do you mean here? Do I have to use that ddol on awake function?

[polar acorn]

If an object is going to be a DDOL you should probably just do it in Start or Awake and be done with it

[summer stump]

There are Unity functions that are called in a certain order. Awake, Start, Update, etc.
It is only called once, and it happens right when the object is created. So it's a good place to do things to initiatalize the object

[polar acorn]

And "put in DDOL" is what is happening here. When you call DontDestroyOnLoad on an object, it gets put in an additive scene named DontDestroyOnLoad that isn't cleaned up when a scene changes. That's how it works internally

[rich adder]

doesn't mean its good lol
Like I said , I don't see the bool staying on in inspector unless you selected wrong enemy

  else if (playerInSeeRange && !playerInAttackRange)
        {

            ChasePlayer();
            Debug.Log("Chasing");
        }```

🤷‍♂️

thats why I said check for Debug.Log("waiting"); log

it could be happening so fast that it could be printing chasing while waiting

[stable portal]

it only waits

the function chase or attack just dont activate

[rich adder]

from the video you sent the log was printing

[stable portal]

only the waiting log yeah

so the enemy was waiting

oh

my bad them sorry

[rich adder]

oh wait no

myb

[stable portal]

yeah

only wait was printing

[rich adder]

ok yeah playerInSeeRange is false

Im guessing it could be a layer issue

[stable portal]

the enemy is WhatIsEnemy layer

[rich adder]

screenshot the Player object

[stable portal]

ok

[rich adder]

yup

layer issue

Your enemy is looking for WhatIsPlayer

your player is Default

[stable portal]

nice it works now but i have one more issue when the enemy is shooting is shoots in itself because of its collider how can i fix it?

[rich adder]

if you dont care about enemy bullets hitting other enemies use
https://docs.unity3d.com/Manual/LayerBasedCollision.html

do like EnemyBullet doesnt hit WhatIsEnemy

or you can just do it when you instantiate bullet , put collider of it and enemy inside Physics.IgnoreCollision (requires reference to bullet collider and own collider)

[stable portal]

ok im going to try it out

[rich adder]

[SerializeField] private Collider myCol
void Foo(){

2D - How do I quickly set the opacity of a panel in code?

[slender nymph]

reference it's image component and modify its color property

[stable portal]

i did this and for some reason it does not work

if (!attacked)
{
Rigidbody rb = Instantiate(enemyBullet, transform.position, Quaternion.identity).GetComponent<Rigidbody>();
if(enemyBullet.TryGetComponent(out Collider coll))
{
Physics.IgnoreCollision(coll, myColl, true);
}
rb.AddForce(transform.forward * 32f, ForceMode.Impulse);
rb.AddForce(transform.up * 8f, ForceMode.Impulse);

        attacked = true;
        Invoke(nameof(ResetAttack), attacksDelay);

    }

[pliant oyster]

I get no suggestions. Usually it shows me whatever the thing has.

[slender nymph]

well you've got several things wrong there. first, you should be using GetComponent, not GetComponents. second, it is a method that you call using ()

[pliant oyster]

Ah okay, thanks

[rich adder]

becaause u write it wrong

ur not grabbing it from the instance

[stable portal]

im not quite sure if i understand what do you mean by that could you please correct the core or explain thanks.🙏

[slender nymph]

you're calling TryGetComponent on your prefab not the object you instantiated

rb is the object you instantiated which is also what you should be calling TryGetComponent on

[raw hamlet]

newbie question but how do I reference a gameobject to a prefab?

[slender nymph]

https://unity.huh.how/references/prefabs-referencing-components

[raw hamlet]

thx

[eager elm]

you can't drag a gameObject from the scene into a prefab

[swift crag]

I don't quite know what you mean by this.

[swift crag]

If you mean you want to reference a game object in a scene from a prefab, then the other answers are correct: you can't reference scene objects from a prefab.

[raw hamlet]

selected ObstacleSpawner

[raw hamlet]

ok

[swift crag]

see the link boxfriend posted.

[pliant oyster]

How do I slowly fade in a panel and its lower attached things? I tried the following but it did not work:

        while (opacity < 100) {
            _settingsMenu.GetComponent<Image>().color = new Color(1f, 1f, 1f, opacity);
            opacity += 0.1f;
        }

I also tried with this, which also did not work:

        while (opacity < 100) {
            _settingsMenu.GetComponent<Image>().color = new Color(opacity, opacity, opacity);
            opacity += 0.1f;
        }

[slender nymph]

loops run to completion. so either you need to put this in a coroutine with a yield inside of the loop, or remove the loop and repeat this code in Update.

also Color uses values from 0 to 1 not 0 to 255

[languid spire]

also opaicty (alpha) in a Color struct is from 0 to 1

[slender nymph]

so an alpha of 100 is the same as an alpha of 1

[pliant oyster]

Ah okay, thanks

[slender nymph]

you also shouldn't be using 0.1f as a magic number like that you should use the amount you want to increase per second then multiply it by deltaTime

unless you don't care that different framerates will cause it to fade in/out at different rates

[queen adder]

hmmm update() isnt called on the frame gameObject.SetActive(true); is called?

    public void Tip(string to)
    {
        Update();
        gameObject.SetActive(true);
        text.text = to;
    }```had to do this on a tooltip code since it pops on where it was last placed first before going to where it should be

[slender nymph]

it very likely depends on what point in the frame you set the object as active

but you do know you can use OnEnable to set things up for when it is enabled, right?

[queen adder]

i call tip when mouse entered something that should have toooltip

[raw hamlet]

I'm still confused after reading the docs. I don't understand. I'm getting

[slender nymph]

are you still trying to drag a scene object into a prefab? beacuse as has already been pointed out you cannot

otherwise you are trying to drag an object that doesn't have the component you are tryign to reference

[raw hamlet]

yes, but I want to know a solution to it because I keep getting

You probably need to assign the obstacleSpawner variable of the DestroyOutOfBounds script in the inspector.```

[slender nymph]

Mouse events are called before Update. so this code runs immediately before update does

[slender nymph]

did you even bother reading the link i sent to you?

[raw hamlet]

yes i did

[pliant oyster]

I don't know what you mean exactly, do you mean that I should do opacity += 0.1f * DeltaTime?

[slender nymph]

then what did you try besides trying to drag the scene object into the prefab?

[pliant oyster]

Because I just used 0.1f as a test value

[queen adder]

this is pretty relevant thanks

[raw hamlet]

I tried to use GetComponent to access the variable

[slender nymph]

no. firstly because DeltaTime is not a thing. second, that would cause it to increase opacity by 0.1 per second. use the number you want to increase per second not your magic number

[slender nymph]

well obviously GetComponent is not going to work unless you have a reference to the object the component is attached to already

[feral ice]

How do i make the green arrow point towards the middle instead of the blue arrow?

[rich adder]

LookAt at uses Forward

[slender nymph]

LookAt makes the object's forward direction (blue arrow) point toward the object. you probably just need to get the direction from this object to the one you want to "look" at and assign it to Player.transform.up

[feral ice]

huh

[slender nymph]

well that's certainly not a helpful response

[feral ice]

oh

set the player.up to something

[queen adder]

(spriteRenderer.sortingOrder <= 0 ? ReferenceHolder.Instance.tileMap : ReferenceHolder.Instance.tileMap1)?.SetTile(transform.position.SnapToInt(), null);
```can `?.` work here?

[slender nymph]

do not use ?. with objects that inherit from UnityEngine.Object

[queen adder]

just gonna get rid of this 🥹

[slender nymph]

that is precisely why you should not use ?. with unityengine.objects

[pliant oyster]

Ok so I put now this:

        IEnumerator ChangeOpacityOverTimeIn() // This makes it run as it is intended to, fading it in.
        {
            while (opacity < 1)
            {
                _settingsMenu.GetComponent<Image>().color = new Color(1f, 1f, 1f, opacity);
                opacity += fadeinTime * Time.deltaTime;
                yield return null;  // Yielding to the next frame
            }
        }

        ChangeOpacityOverTimeIn();
```The "fadeinTime" I set in the inspect box to "2" but it still pops in instantly

[slender nymph]

null conditional (?.) and other null related operators do a pure null check. they do not use the overridden == operator on UnityEngine.Object to check for unity's fake null when an object has been destroyed. they have no way to access that overridden operator so when you use them on a destroyed object you still run into missingreferenceexceptions because those objects aren't actually null

[slender nymph]

well for one you're not starting the coroutine correctly

[pliant oyster]

How do I start it correctly?

[slender nymph]

by using StartCoroutine

[pliant oyster]

Ok now it broke. It pops in instantly, then when I close it it closes instantly, then when I open it again, the closing button appears but the panel does not

[slender nymph]

the code you've shown should make it fade in and out in 0.5 seconds (assuming that fadeinTime and fadeoutTime are both 2)
if it somehow isn't working, then some other code is affecting it, or those variables i just referred to are set way higher than you think they are

[slender nymph]

great! then either some other code is affecting it, or it is actually taking a whole half of a second

or you're looking at the wrong object

[stiff stump]

does the OverlapBoxAll size height and width or is it half of height and half of width?

[pliant oyster]

Ok I changed the while (opacity < 1) line to while (opacity < 255) and now the panel appears again, though again it appears instantly.

[slender nymph]

it's like you haven't even been listening

[pliant oyster]

Apologies but I have some mental disabilities, so that might be why

[solemn fractal]

Is there a way to have 1 object parent and 1 object child, where both have colliders, and the script that I have on the parent will say that when other.comparetag("bullet") happens, it will do some logic. BUT the prob is that when the bullet enter the child circle collider and not the parent collider that is also a circle and its inside the child collider, it also counts and I want just to count when it hits the parent.

tried like 5 dif ways to achieve that but seems that I cant separate one for the other. Is there a way to do this?

[rich adder]

ignore layer or ignore collision?

[solemn fractal]

what do you mean? can you explain better?

[rich adder]

exlude the child layer from collision messages with incoming bullet

example
https://docs.unity3d.com/ScriptReference/Physics.IgnoreCollision.html

[solemn fractal]

oh ok, will look into it, thank you

[rich adder]

https://docs.unity3d.com/Manual/LayerBasedCollision.html
this one if you want to completely ignore each other and not do it every function call

[pliant oyster]

I managed to fix it.
https://hatebin.com/bunouungzl
This also changes the opacity of its children, and it works with my current project.

[distant mesa]

Hey!
I have this idea to get some Realtime data from NodeRED into my unity project. I've researched and I came across Websockets and REST API's.
Which one would be best? or are there any other, better, solutions?
I work with a HoloLens so performance is important to consider too.

[rich adder]

whats NodeRED

[distant mesa]

Its something my collegues work with, i think network/server stuff that holds data

personally dont know much of it

[slender nymph]

Ah so the issue was that child object of the panel weren't being affected. You should maybe mention important details like that next time

[distant mesa]

but basically from a web page

[rich adder]

if you need more like realtime messages websockets make more sense

[distant mesa]

"Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways."

yeah like once per few seconds

[rich adder]

thats a very generic statement

[rich adder]

a rest api is fine

depends

[distant mesa]

but if it has to be faster, websockets would be the go-to?

[rich adder]

they have diff use case

[strong wren]

Are you frequently transferring data?

[rich adder]

Websocket is good for keeping a connection open and transfer data frequent

[strong wren]

WebSockets are a bit more efficient for continuous data than HTTP.

[distant mesa]

Ohhh okay

good to know

does it take up alot of performance?

[pliant oyster]

That wasn't the issue even. The issue was that the panel did not fade in and out correctly. The issue was the order of how things were done.

[rich adder]

its very efficent

[distant mesa]

ooo great ty!

Reporting bugs

🪲 To make bug reporting as quickly as possible, we made a bug reporting application for you. When running Unity choose Help->Report a Bug in the menu, or you can access it directly through the executable in the directory where Unity is installed. It will also launch automatically if you experience a crash.

📝 If your bug report is to do with Documentation, either an error, typo, or omission, you can report it by scrolling to the bottom of the page where you found the issue and click ‘Report a problem on this page’!

💡If your report is to do with a new feature idea, you can check the Unity Product Roadmaps page to see if your idea has already been planned.

For more complete instructions on how to report bugs, access: https://unity3d.com/unity/qa/bug-reporting

[sharp wyvern]

ollow by a crash report popup

[rich adder]

could probably be an infinite loop in your code

[sharp wyvern]

it's not a bug. it's def me

nah, I just enabled windows firewall for... reasons.. now unity wont open.

if I disable it it will.

[cosmic dagger]

can't you allow Unity through firewall settings?

[sharp wyvern]

tried the stuff I found online, that got me to ALMOPST get unity loaded, but it still crashed after that popup

[sharp wyvern]

yes, and I did, and that seem to MOSTLY work.. but obviously, not completely

[cosmic dagger]

Ahh . . .

[rich adder]

could be Visual Studio also

[sharp wyvern]

used this: https://docs.unity3d.com/Packages/com.unity.live-capture@2.0/manual/setup-network.html as my guide.

[sharp wyvern]

created a rule to allow that also, alas I CANNOT create a rule for the DLL mentioned in that popup.. only .exes

[rich adder]

hmm strange, not sure why it would crash it

check editor logs mybe

[sharp wyvern]

(also that dll shows up in the projects' libraray folder, and I got a zillion projects)

[sharp wyvern]

good thinking, alas, I did check those, and I do see a stack trace in there, but not sure how to use that info to set the right rule..

I even tried a to create a rule to allow ALL connections from 127.0.0.1, figuring that gonna cover everything originating on my own system- alas, didn't help

[orchid trout]

    private void ApplyChangesToMaterial(Material material)
    {
        material.SetColor("_Color", colorToApply);
    }

    private void ApplyMaterialPropertyBlock()
    {
        thisRenderer.GetPropertyBlock(propBlock);
        propBlock.SetColor("_Color", colorToApply);
        thisRenderer.SetPropertyBlock(propBlock);
    }```

How can I refactor these methods together so that as I expand this I don't have to maintain two separate method trees of duplicate code, specifically the:
        material.SetColor("_Color", colorToApply);
        propBlock.SetColor("_Color", colorToApply);
these two lines ![UnityChanThink](https://cdn.discordapp.com/emojis/885169594560544800.webp?size=128 "UnityChanThink")

the ideal result would be something like a third method that does the assignment and can have either the material or material block passed into it?

I think my problem is that materials and material property blocks have technically nothing in common? like I cant cast from one to the other or whatever?

[sharp wyvern]

you can can overload a function, meaning you can create two versions of it, one that takes a property block and one that takes a material. not sure if that is what you need tho

[orchid trout]

Yeah moreso my problem I am trying to avoid is having to maintain two duplicate codebases as I expand this class

one for material property blocks, one for materials, both identical otherwise

[sharp wyvern]

afraid there is no way around that.. it simply requires different code to change the color for a material and a propertyblock. However with the overloaded function you shouldn't need to ever write that code again...just call that function when you want to chaNGE THE COLOR, AND PASS IN WHAT YA HAVE.

oops caps,

[orchid trout]

I might have to settle for that Thanks, Ill try that out for now then

[swift crag]

So did my earlier suggestion wind up working?

(the goal is to preview different colors in the editor, but to also get SRP batching at runtime)

giving each renderer its own material in the editor is confusing, but using material property blocks breaks SRP batching

[sharp phoenix]

BoxCast

[solemn fractal]

hey guys, already tried all the things that people here told me to try, but none works. I have this situation. 1 object boss with 4 child minions. Minions they have a collider each, and boss also has a collider. Inside the boss script I have the method OnTriggerEnter2d. But if do like that as below ```cs
private void OnTriggerEnter2D(Collider2D other) {

    if (other.CompareTag("Bullet")){  

         _currentHealth -= _bullet._playerBulletDamage;

    } 

}``` no matter if I hit the minions or the boss is the same. And I cant find a way to differentiate and say NO i want the hit to count only when hits the boss. Boss and minions are using dif tags.

[tiny bloom]

Where do u get the id of the bool from?

[slender nymph]

you can use Animator.StringToHash for that

or if you don't want to do that and don't mind using a string in that call just use its name

[sturdy lintel]

I am using this script to zoom using Alt+Scroll Wheel. But there seems to be an issue. Once I zoom & reach at a point where I cannot zoom-in further, I am not able to zoom-out. But If I zoom-in normally then I can zoom-out

using UnityEngine;

public class CameraController : MonoBehaviour
{
    private float zoomSpeed = 5f;
    public GameObject cameraFramePrefab;
    [HideInInspector] public GameObject CameraFrame;

    void Awake()
    {
        CameraFrame = Instantiate(cameraFramePrefab, new Vector3(0f, 0f, 0f), Quaternion.identity);
    }

    void Update()
    {
        Vector3 lookAtPosition = CameraFrame.transform.position;

        // Dolly: Alt + Scroll Wheel
        if (Input.GetKey(KeyCode.LeftAlt) && Input.GetAxis("Mouse ScrollWheel") != 0f)
        {
            float scrollWheel = Input.GetAxis("Mouse ScrollWheel") * zoomSpeed;

            Vector3 dollyDirection = lookAtPosition - this.transform.position;
            if (dollyDirection.magnitude > 5f)
                this.transform.position += dollyDirection.normalized * scrollWheel;
        }
    }
}```

[rich adder]

are you sure you setup Mouse ScrollWheel correct?

why not Input.mouseScrollDelta

[sturdy lintel]

how do I do that, I directly started coding

[sturdy lintel]

wait, I'll try this, never heard this one before

[rich adder]

https://docs.unity3d.com/ScriptReference/Input-mouseScrollDelta.html

[weary moss]

how can i make a loop that runs alongside with Update? E.g a variable that goes up by one every frame and stops once it gets to a certain number

[slender nymph]

use an if statement inside of update. if variable is less than threshold add 1

[rich adder]

would this work maybe ?

 IEnumerator Foo()
    {
        var frames = 0;
        while(frames < 3000)
        {
            frames++;
            yield return new WaitForEndOfFrame();
        }
        yield return null;
    }```

[sturdy lintel]

void Update()
{
  Vector3 lookAtPosition = CameraFrame.transform.position;
  float scrollWheel = Input.mouseScrollDelta.y * zoomSpeed;

  Vector3 dollyDirection = lookAtPosition - transform.position;
  if (dollyDirection.magnitude > 5f || scrollWheel < 0f)
   {
      transform.position += dollyDirection.normalized * scrollWheel;
   }
}```
So I updated the script as per your advice. And now I am able to zoom-out. But one issue that's happening now is, if i rapidly scroll then my camera is going beyond the bounds I set & then zoom-out doesn't work

[rich adder]

which is the bounds ?

[sturdy lintel]

I don't want my camera to go nearer than 5f from the LookAtPosition

[nimble sorrel]

My canvas doesn't seem to be responding to the player input. I'm able to adjust the values just fine in the inspector, but the sliders and buttons don't seem to be responding in the game window
This forum post https://forum.unity.com/threads/sliders-wont-slide.283570/ suggested it had something to do with file hierarchy, and changing that is indeed how I got it working in a separate scene, but I still don't fully understand what was different about that separate setup and I'd rather know the underlying issue rather than just trial and error-ing it again

[rich adder]

just use distance check

oh I see the magnitude

[sturdy lintel]

my if condition is wrong? I have checked the magnitude

[rich adder]

check the number make sure its correct

its prob not

that if statement is sus tho

[twin bolt]

Why is the int jumping up to 5 even though the texts are null?: foreach (TMP_Text e in InputFields) { if (HaveChildren != 5) { if (e.text != null) { HaveChildren++; } else { HaveChildren = 0; } } }

[crude prawn]

is there a better way to do this? on sprint() i just put the playerspeed to 5 and on unsprint i just put it to 2

[slender nymph]

yeah just have one method you subscribe to both events and change it based on the context passed in

although you probably wanted started and canceled rather than performed and canceled if you just want to start when the button is first pressed down and end when it is released (performed can act the same way if you don't have anything interactions or whatever on your action)

[rich adder]

how you know is null

[twin bolt]

I'm trying to check if the text is empty.

[rich adder]

so use !string.IsNullOrEmpty(e.text)

[sturdy lintel]

yeah, I did, it's correct. Not able to solve the issue

[crude prawn]

thank you

[rich adder]

you havent specified which direction is scrolling and which one is the limit

[twin bolt]

The int still jumps up to 5

even though the texts are null

[sturdy lintel]

So my scrolling is towards the lookAtPosition, which i am calculating, first line of Update() & I don't want my camera to zoom through it, so I added a rough 5f value

[slender nymph]

show the full context

[twin bolt]

{
    public TMPro.TMP_Text[] InputFields;

    public int HaveChildren;
    bool Checked;

    public GameObject button;

    void Update()

        {
            if (HaveChildren != 5)
            {
                if (!string.IsNullOrEmpty(e.text))
                {
                    HaveChildren++;
                }
                else
                {
                    HaveChildren = 0;
                }
            }
        }

        if (HaveChildren != 5)
        {
            button.GetComponent<CanvasGroup>().alpha = 0.03f;
            button.GetComponent<CanvasGroup>().interactable = false;
        }


        if (HaveChildren == 5 && !Checked)
        {
            Check();
            Checked = true;
        }
        
    }

    public void Check()
    {
        button.GetComponent<CanvasGroup>().alpha = 1;
        button.GetComponent<CanvasGroup>().interactable = true;
    }   

}```

[delicate portal]

Hey!
How do I set an animation float for a blend tree using the animated object (animal) and the followable (player) distance?
I want that if the animal is near the player, it should be around 0, and if the player is far away, it should be 1, which would indicate the animal running. I tried doing some math with magnitudes and vectors but I didnt figure it out.

Thanks!

[slender nymph]

you never reset HaveChildren to 0. so if there is even one non-null object in there, after 5 frames it will be 5 and it will always be 5 after that

[twin bolt]

So how should i go by doing this?

[rich adder]

its probabnly scrollWheel < 0 being true

[frosty hound]

You need to get the distance between the two objects and then use lerp to map the distance between two values 0 and MaxSpeed.

[sturdy lintel]

how should I fix it then?

[rich adder]

why do you want that there

a better solution would prob be clamp

[sturdy lintel]

I removed it. But then my zoom-out stops all-together.
if (dollyDirection.magnitude > 5f)

[slender nymph]

actually wait, there is one point where you reset it to 0. but you should probably be checking for InNullOrWhitespace not IsNullOrEmpty

[twin bolt]

Ok

[slender nymph]

but for future reference, use the debugger or print useful information if things are not happening the way you expect. don't just expect everyone else to debug your code for you

[twin bolt]

The int somehow still jumps to 5

[slender nymph]

well what debugging have you tried?

[rustic verge]

how do i fix this the first image is my code

[slender nymph]

what have you actually done to make sure that the values you are using/checking are actually what you expect them to be?

[delicate portal]

I did transform.pos1 - transform.pos2 for distance

Use lerp?
