Hi
i wrote this script from a you tube video
when i enter playmode it stucks like this

i was making a pulse script

knotty sun
#

you have an infinite loop in Beat

leaden ice
knotty sun
#

In fact I'm not sure why that even compiled

rigid island
#

yes wouldnt it need to return value?

leaden ice
#

@lean quiver hint: You want to add some kind of delay inside your loop in the coroutine.

knotty sun
#

it needs a yield

lean quiver
#

Wait

rigid island
lean quiver
#

yield return new WaitforSeconds()

#

yeah

#

it works

rigid island
#

if the time doesn't change you can just create it before while loop, or just use DeltaTime end skip the WaitFor (you need nested while for this one)

lean quiver
#

alr

#

tysm

rigid island
# lean quiver it works 
  IEnumerator Timer(float timeBetween)
  {
      var waitTime = new WaitForSeconds(timeBetween);
      while (true)
      {
          //do something before first wait
          yield return waitTime;
      }
  }
  IEnumerator Timer(float timeBetween)
  {
      while (true)
      {
          var time = 0f;
          //do something before first wait
          while(time < timeBetween)
          {
              time += Time.deltaTime;

Hello, does anyone know why my this: Mathf.InverseLerp(-140, 140, percentage) only returns very small values and doesn't change? percentage is a float in my script that slowly increases, but the function barely increases, even when waiting for a long time. Even when I make percentage public and edit it ingame, visually nothing changes, and the float that's returned by the function increases by nothing above 0.01.

knotty sun
#

what values do you give to percentage

leaden ice
#

if you give it (-140, 140, 0) it will give you 0.5

#

(-140, 140, -140) will give you 0
(-140, 140, 140) will give you 1

#

Are you perhaps confusing InverseLerp with Lerp?

wind meteor
#

Okay I see... πŸ€”

leaden ice
#

Your description of "percentage is a float in my script that slowly increases" sounds like you want Lerp

#

not InverseLerp

wind meteor
leaden ice
wind meteor
#

But doesn't lerp work with time?

leaden ice
#

Lerp does exactly what you're trying to do

#

time can be involved

#

but doesn't have to be

#

public static float Lerp(float a, float b, float t);

Linearly interpolates between a and b by t.

The parameter t is clamped to the range [0, 1].

When t = 0 returns a.
When t = 1 return b.
When t = 0.5 returns the midpoint of a and b.

wind meteor
#

okay no you're right

I'm setting up a power-up, with an ingame object that has the Powerup tag, which should alter my character's walkspeed to make them faster. However, the debug isn't being triggered at all, which means that it isn't even interacting with the collider. Any thoughts on what this could be as an issue? I'm using a character controller, which caused some trouble for me when it came to transforming the position, but the solution for that was to go into physics in project settings and enable Auto Sync.

 private void OnTriggerEnter(Collider other)
    {
        if (other.tag == "Powerup")
        {
            //This destroys the object once touched, and changes the jump force.
            Destroy(other.gameObject);
            Debug.Log("POWERUP HERE");
            walkSpeed = 14f;
            StartCoroutine(ResetPower());
        }
    }
    //We're setting up a coroutine to time the powerup duration.
    private IEnumerator ResetPower()
    {
        yield return new WaitForSeconds(10);
        walkSpeed = 7;
    }

I'm trying to set a color property on a shader for a mesh and it's not working.

I've created this simple shader (unlit, colored): https://discussions.unity.com/t/unlit-color-blend-with-texture-simple/758208

Added it to a mesh, and made a local copy at runtime with:

        [SerializeField] private MeshRenderer MoveMeshRenderer;
        private Material _moveMaterial;
        private void Awake()
        {
            MoveCursor.SetActive(false);
            _moveMaterial = new Material(MoveMeshRenderer.material);
            MoveMeshRenderer.material = _moveMaterial;
        }

Then I'm trying to set the color of the shader with:

                Color random = new Color(Random.Range(0f, 1f), Random.Range(0f, 1f), Random.Range(0f, 1f));
                _moveMaterial.SetColor("Main Color", random);

No effect though. Works fine setting the exposed color property in the editor, but nothing in play mode.. Am I doing the "create a local material" thing correctly in Awake?

dry crag
knotty sun
#

Indeed, apologies, but they were wrong to redirect you to here as this is not a code issue

open plover
modern creek
#

when, at awake()?

open plover
#

Then MoveMeshRenderer.material = material

modern creek
#

do I have to make a local copy of the material any time I want to change a value on the shader..? I don't understand

open plover
#

Could you try MoveMeshRenderer.material.SetColor

modern creek
#

sure, standby

#

amazing, that works.. but why..?

open plover
#

Because in the your code, you change the _moveMaterial

#

When you say MoveMeshRenderer.material = _moveMaterial

#

You dont automatically access the movemeshrenderers material

#

By accessing _moveMaterial

#

Someone might explain it better

#

Ok think like this

#

int a = 5;

#

When you say 5++;

#

Do you change the value of a?

#

You must say a++ to change the value of a

modern creek
#

I mean, obviously, but that's for a primitive.. I assumed (incorrectly?) Material was a reference type

open plover
#

I think it creates a copy of that material

#

And assigns it to movemeshrenderer material

modern creek
#

ie:

public class MyClass
{
  public Color color;
}
public class Material
{
  public Color color;
}

...
MyClass myClass = new();
myClass.color = Color.pink; // Great, it's pink.

Material myMaterial = MeshRenderer.material;
myMaterial.color = Color.pink; // Doesn't work. Why?
open plover
#

At least that explains it

knotty sun
modern creek
#

I already created the copy (and saved the reference) at awake time.. that's why I don't understand why setting the color prop of the memoized Material doesn't work, but accessing the (same?) material directly through the mesh renderer does

#

is this just "one of those things" about mesh renderers/materials that I have to remember doesn't work normally? I mean, it's working beautifully, I just don't really know why

open plover

#

It's like the ParticleSystem but backwards. Its modules are structs, so you need to make a local variable to modify one of its properties, but you don't need to assign it back to the PS because it's still magically linked to the PS, even though it's a value type

modern creek
#

ohhhhhh, the meshrenderer material module is a struct..?

#

that makes sense ... and is utterly confusing at the same time

simple egret
#

No it's a class

modern creek
#

I stumbled the same way when first working with particle systems

simple egret
#

That's why I said it's backwards, structs behave like classes (particle system) and classes like structs (mesh renderer material)

#

The material you get when accessing the .material property is a copy

modern creek
#

ok, interesting

#

So I'm assuming my pattern is correct then, here? ie: create copy in awake, save reference to it, assign copy to mesh.material, edit at runtime with mesh.material.setcolor, and destroy at ondestroy with unity.object.destroy(_material)?

late lion
#

I wouldn't describe Renderer.material as if it's a struct, because it will only return a copy the first time you access it. It's best to think of Renderer.sharedMaterial as the actual variable holding the currently set material and Renderer.material as Renderer.GetInstancedMaterial(), where Unity will copy the currently assigned sharedMaterial if it hasn't already, assign it to sharedMaterial and then return it.

late lion
#

If you want to manage the material copy yourself, you should stick to always using Renderer.sharedMaterial to avoid the Unity copy. Or you can just let Unity manage it for you, use Renderer.material and just remember to destroy it afterwards because Unity won't do that.

modern creek
#

K. If I use renderer.material how do I destroy the copy? Do I need to save a reference to it and destroy that? (ie private Material _material; _material = Renderer.material;), or do I just Destroy(renderer.material) at destroy time?

quartz folio
#

Either or. I'd save a reference personally

modern creek
#

Like, will this leak?

image.png
#

ie - does accessing the .material property instantiate a local material from the shared material?

cold parrot
#

You are accessing .material, so it will make a copy. It only β€˜leaks’ if you don’t destroy it.

chilly surge
#

It's unfortunate that things don't implement IDisposable, and things like .material which has implications is a property, I'd prefer it being a method instead.

#

I wrap my instantiations of Unity objects in an Allocated<T> : IDisposable to make it clear that something is allocated and must be disposed (the Dispose calls Destroy for me) to help with the problem, a poor man's Rust ownership.

alright, so i'm making my player attack an enemy and reduce it's health, and to make things safe, how should i got about limiting it with properties?

#

just make set a function that reduces enemy health by value? would make sense, since i do need to clamp the health so it doesnt go past 0

Hey, how can I convert string float 1.5 into actual float if its missing "f"?

This doesn't work for me

its feasible in the sense that it has been done already. though i wouldnt call this an easy feature at all. your video reminds me of 7 days to die, the ground destroys in a very similar way in that game.
maybe look into what other games actually save to see how you should do this. people who play these kind of games do expect loading times when initially launching (minecraft, terraria, 7 days to die) so i wouldnt stress too much if the game takes a minute to load.

"3.5" won't convert to float for me

#

I am trying differnt things at this point

# 
       dict.TryGetValue(key, out string v);
       Debug.Log(v);
       float.TryParse(v, out float v2);
       Debug.Log(v2);
       string v3 = v + "f";
       float.TryParse(v3, out float v4);
       Debug.Log(v4);
#

v2 is 0
v4 is 0

#

v is "3.5"

lean sail
#

it works fine for me. the "f" would indeed cause it to not work

upper pilot
#

That's why I am lost

#

I will try to just type "3.5f" in a string and see

lean sail
#

im not sure why you insist on the f with tryparse. its not needed

upper pilot
#

oh ok let me try without, I misread your last message

#

huh it needs to use comma?

#

1,5

#

ok that works with ,

#

Didn't think that would be the case as you don't type 3,5f in the script

lean sail
cosmic rain
lean sail
#

though i am surprised that 1.5 didnt work for you, because i tried it and both "1.5" and "1,5" convert properly. although 1,5 is 15 so it isnt the same number

upper pilot
#

"3,5" converted to 3.5, but "3.5" to 0

#

Let me try that option, I already wrote some code to fix it :c

# 
    public static float GetParsedFloat(Dictionary<string, string> dict, string key, float defaultValue)
    {
        if (dict.TryGetValue(key, out string v))
        {
            v = v.Replace('.', ',');
            float.TryParse(v, out float parsedVal);
            return parsedVal;
        }
        else return defaultValue;

        //return dict.TryGetValue(key, out string val) && float.TryParse(val, out float parsedVal)) ? parsedVal : defaultValue;
    }

I liked the simple 1 line return tho, so I will try to fix it with your link

#

lean sail

upper pilot
#

Yeah thanks, I got there almost. It didnt auto complete culture info, only System.IFormatProvider πŸ˜„

#

That works, thanks for the help! Sometimes you get some weird quirks like this, I'd expect it to parse them the same for everyone, not based on system settings.
I wonder if system settings are passed after compilation or if it would check each user system to decide how to parse floats?

#

Now that it's specified it won't matter tho

lean sail
#

i think in newer versions of c# you dont need the NumberStyles.Float part. because the docs i linked has declarations which shows 3 parameters, but in whatever version unity uses it didnt work

upper pilot
#

Yeah I had to use all of them

#

I have only 4 overrides, 2 of which use char I think

Does anyone ever use visual scripting in addition to c#? I can think of some situations or systems where being able to see the logic flow laid out with nodes would be beneficial, but I've never used visual scripting, so curious what others think.

# steep saddle Does anyone ever use visual scripting in addition to c#? I can think of some sit...

I use Shader Graph, which is a form of visual scripting. The main advantage is that it lets me see the preview of particular parts of the graph. It was also more compatible than a code itself (since it generates code anyway), while in the past some code scripts failed to work after changing the renderer pipeline.

I think visual scripting is the most appealing for people who don't know how to code. You could code some nodes, and then let artists/designers use it. I think it's a common practice to use some sort of graphs to "code" story flow (dialogues, quests etc.).

After getting an error for not having put a scene I was loading into build settings, I thought to myself, if I'm going to have maybe a thousand scenes in my game, will I really have to put all of those scenes into build settings and manage them? Or am I using scenes wrong by making one for each level I create?

#

Or is there an alternative way to load scenes without having to put them into build settings? (which I doubt...)

Hi all, in a 2D game settings, I have this two objects (the character, and a retractable tongue) that I have a line renderer connected representing the tongue, and using fixedupdate to connect them together (setting the positions of the two objects). The issue Im having is when these objects move in a relatively high velocity, the line renderer struggles to keep track and starting to lag behind visually. Is there a better way to draw a tongue of a character? It acts almost like a grappling hook, zip line mechanic so I would need to render that tongue is a relatively high velocity

#

potentially I could limit the max velocity and instead move the backgrounds etc to mimic a high speed game feel? But I feel like there has to be a better way of dealing with this

    public void UpdateTonguePosition(Vector3 Position)
    {
        lineRenderer.SetPosition(0, Position);
        lineRenderer.SetPosition(1, transform.position);
    }

This is the code that I am now calling in LateUpdate, and was calling in FixedUpdate. From my understanding FixedUpdate are called more frequently than Update, which means that Im updating the Linerenderer's position more frequently in FixedUpdate.

#

Wouldn't more frequently = more accurate lines?

#

ahhh because in Late Update, the calculations for velocity/rigidbody is already executed, THEN I update the line renderer, giving me the most accurate lines

#

I think that makes sense

knotty sun
open basalt
#

hahah yea Im aware of that, just trying to understand why

hard estuary
# open basalt holy, this was it. This fixed the issue I was having. Thanks! However, I'm a bit...

FixedUpdate is meant to be called in constant intervals (the interval duration depends on your project's settings). Update and LateUpdate on the other hand are run once per frame. Intervals are as long as the intervals between frames. Let's assume your FixedTimestamp is 0.02 (default value), which means FixedUpdate will be run 50 times per second in constant intervals of 0.02s. If your current frame rate is 30fps, then it will be usually called more often than Update/LateUpdate. If you current frame rate is 60fps, then it will be called less often than your Update/LateUpdate.

open basalt
#

"If the function is in Late Update, in that one frame, the rigidbody's movements are already calculated, thus when we update the line renderer, it gives the most accurate position as per that frame"

#

it would also be smoother because it's only done every frame (visiually would be smoother)

Looked it up and a string's size will equate to 26 + length * 2. It needs to store a ref to the underlying array, the string length, the capacity, etc. which is where parts of the 26 comes from. Then, 2 bytes per character

Should I instead just have an array of Players?

Hey, how can i apply a transformation to the position of a 3D point in space to rotate a certain amount of degrees in an axis around another point? Here's a sketch of what i mean in 2D for simplicity. Hope that makes sense, I'm really struggling to get my head around it

image.png
hexed pecan
#

The rotation could be something like Quaternion.AngleAxis(degrees, axis);

#

So basically vec - pivot converts it into a vector relative to the pivot
Multiplying the vector with a quaternion will rotate the vector
Then add the pivot offset back to the vector

I have an issue with a rotation of an object based on player mouse movement. For 60 fps it works well, but for 500 fps there's almost no rotation. Multiplying the sensitivity by 10 would make the 60fps one too fast and the 500 one decent. Any ideas on how to fix it?

Edited:
float mouseX = Input.GetAxisRaw("Mouse X") * sensitivityMultiplier;
float mouseY = Input.GetAxisRaw("Mouse Y") * sensitivityMultiplier;

    Quaternion rotationX = Quaternion.AngleAxis(-mouseY, Vector3.right);

Do not multiply mouse input by delta time

somber nacelle
#

don't multiply mouse input by deltaTime, it is already framerate independent so you just end up with stuttery controls

west lotus

Heh first

@west lotus @somber nacelle thanks for the advice, I did try that previously but I have the same result. As in, if I have sensitivityMultiplier set to 1, on 60fps it moves well, but on 500 it barely moves (I'll remove the Time.deltaTime anyway)

Having 2 serializable classes: the 1st one, which has a List of the 2nd ones, and the 2nd one, which has to access a boolean from the 2nd one in the method, which is called with the custom Attribute when the field is changed in the inspector, what would be a way to do this without getting a stack overflow on serialization?

I control the animations in the game through the blend tree. I want to change the idle animation to rifle idle animation when my character picks up a gun. How can I do this? I tried to open a different blend tree and control the idle transitions there, but I gave up because there were some problems between the transitions with the other blend tree.

Hey, I'm trying to let my player grab objects and and put them down somewhere else but i'm facing some trouble. When the player grabs the object, the "grabPoint" and the object move to a completley different spot on the player when grabbed. I'm new to coding in c# and in unity so sorry If i explained it bad. Any help would be appreciated.

This is my grabObject script

Hey all, I'm trying to create my own see through portal system (Similar to games like portal) and am working on rotating the camera on the other side of the portal so that it doesn't appear static, here's my code:

    private void RotatePortalCamera(Transform entryPortalTransform, Transform exitPortalTransform, Transform exitPortalCameraTransform)
    {
        Vector3 offset = entryPortalTransform.position - _playerTransform.position; // Offset between the entry portal and the player
        
        float angle = Quaternion.Angle(entryPortalTransform.rotation, exitPortalTransform.rotation); // Difference in angles between 2 portals to adjust focus point accordingly

        Quaternion rotation = Quaternion.AngleAxis(angle, Vector3.up); // Rotation quaternion around the exit portal's axis

        Vector3 focusPoint = exitPortalTransform.position + (rotation * offset); // Apply rotation to offset to get the focus point for the camera
        
        exitPortalCameraTransform.LookAt(focusPoint);

        // Line renderer for visualisation
        _offsetLine.SetPosition(0, exitPortalTransform.position);
        _offsetLine.SetPosition(1, focusPoint);
    }```
The issue is, I cant for the life of me figure out how to move the focus point such that the camera looks the right way for every circumstance. The line represents the direction the camera is looking, and the sphere is acting as the player's POV.
In the circumstance in the first image, it works, however if I was to look through the other portal instead (shown by the second image), the direction it looks is 180 degrees off, requiring me to use Vector3.down as the axis instead of Vector3.up. I think this is where the problem stems from, but I cant figure out a solution that works in every position of the 2 portals, and thinking about it in 3D is really messing with my brain. Does anyone know what i may be able to do to solve it?

Weird problem, I'm trying to solve. I'm creating a sword builder, with different models being instantiated on top of each other. However, the end result does not look neat at all, and I'm trying to figure out what the problem is.

using UnityEngine;
using UnityEngine.UI;

public class SwordBuilder : MonoBehaviour

    [Header("Sword Parts Pools")]
    public GameObject[] bladePrefabs;
    public GameObject[] crossguardPrefabs;
    public GameObject[] hiltPrefabs;

    public Slider hiltSlider;

    private GameObject currentBlade;
    private GameObject currentCrossguard;
    private GameObject currentHilt;

    //Access AudioManager script here.
    AudioManager audioManager;

    private void Awake()
    {
        audioManager = GameObject.FindGameObjectWithTag("Audio").GetComponent<AudioManager>();
    }

    void Start()
    {
        bladeSlider.maxValue = bladePrefabs.Length - 1;
        crossguardSlider.maxValue = crossguardPrefabs.Length - 1;
        hiltSlider.maxValue = hiltPrefabs.Length - 1;

        BuildSword();
    }

    public void BuildSword()
    {
        ClearExistingParts();

        Vector3 currentPosition = transform.position;
        //Instantiate and configure the hilt
        currentHilt = Instantiate(hiltPrefabs[(int)hiltSlider.value], currentPosition, Quaternion.identity);
        currentHilt.transform.parent = transform;
        float hiltHeight = currentHilt.GetComponentInChildren<Renderer>().bounds.size.y;
        currentPosition += Vector3.up * hiltHeight;

        //Instantiate and configure the crossguard above the hilt.
        currentCrossguard = Instantiate(crossguardPrefabs[(int)crossguardSlider.value], currentPosition, Quaternion.identity);
        currentCrossguard.transform.parent = transform;
        float crossguardHeight = currentCrossguard.GetComponentInChildren<Renderer>().bounds.size.y;
        currentPosition += Vector3.up * (crossguardHeight);

        //Instantiate and configure the blade above the crossguard.
        currentBlade = Instantiate(bladePrefabs[(int)bladeSlider.value], currentPosition, Quaternion.identity);

        if(currentCrossguard) Destroy(currentCrossguard);
        if(currentHilt) Destroy(currentHilt);

Hello ... would someone be willing to throw me a simple syntax example for performing a Binary Search on a NativeArray<float>? I've found reference to the NativeSortExtension BinarySearch<T>(NativeArray<T>, T) definition (https://docs.unity3d.com/Packages/com.unity.collections@2.2/api/Unity.Collections.NativeSortExtension.html#Unity_Collections_NativeSortExtension_BinarySearch__1_Unity_Collections_NativeArray___0____0_)) , but can not for the life of me nail down the syntax for utilizing it ... I keep bumping up against "NativeArray<float> does not contain a definition for BinarySearch", despite adding the Unity.Collections namespace. Doesn't appear to be any existing examples in the Googlesphere ... Is there something more that's required before referencing methods from the NativeSortExtension class?

^ Looking for proper syntax for the TerrainHeights.BinarySearch(value) line.

Binary Search looks to be an extension method so your call it as a method from your instance.

#

I'm assuming the error line is the Array.BinarySearch

valid latch

The NativeArray<T>.BinarySearch, yes.

Commented out Array.BinarySearch() version works, but can't put it into the job system.

using UnityEngine;

BinarySearch method should be in NativeSortExtension class in Unity.Collections.

Is it the only error that you've got?

Let's say i have 3 textures, 3 16x16 and one 32x32. How would i desing an atlas packer that handles that?

I just found a blog entry and it looks nice, but it seems like i requires power of two sized textures to work

It's not really a problem for me tho, more for modders but idk

#

Forge docs even say explicitly to not use non power of two textures

Hey everyone. I am wondering whats the best way to handle Unity and system.tasks asynchronous scopes. I am currently running a statemanager that is handling the main app state with Tasks, awaits and callbacks to receive correct app status through different systems like network connections, webserver sync, device capabiliy checks and so on. This works fine so far, but the more I move the logic of states to tasks, I run into the issue, that most unity parts are main thread bound. Currently I am checking and updating the raw state and then dispatch to mainthread for the underlying systems to react to that state. Is there any smarter choice of doing so, or should this already be the best way to separate it and only let task do data driven parts and then return to mainthread to visually update the system and use unity internal calls?

hard estuary
#

@primal wind For me, the resolution had a significant change when I tested the effectiveness of some compression algorithms. As stupid as it sounds, sometimes files took less space just because I increased their size to fit the power of 2 restrictions. E.g. I've just added a test image of size 1023x2047 and it took 8MB, but when I increased it to 1024x2048 it took only 1,3MB of space due to compression. Similar effect can be achieved by configuring it to automatically change its size to fit the power of 2 restriction.

Is there any way to make my non-serializable Func<bool> persistent?

tacit vine
#

did someone found a way to give a button event in unity a enum parameter?

cosmic rain
gray mural
cosmic rain
#

Like, the method that it points to?

gray mural
#

It's a Func<bool>, which is assigned in a method. On script compilation, it disappears, so I have to call the method once more

cosmic rain
#

Well, there isn't an easy way. You'll probably need to implement a custom serialization of functions in your project for that. At which point it's not gonna be a func anymore.

#

Serialize the full name of the method and use reflection on load to reference the correct function again.

#

You might or might not be able to get that info from the func. You'll need to check the docs.

gray mural
#

Alright, this was a bad solution to a bigger problem. I've figured out another way to do it, so I'll just remove this Func

#

Thank you for your help

cosmic rain
#

Actually, the above would only work for static functions anyway. For a non static function it's gonna be several times more complicated

gray mural
#

Well, I can actually retrieve the function by calling the suitable method again in OnEnable, but this doesn't seem like a clear implementation

Hey everyone! Hope y'all doing well - I come here with a problem I need solving.

#

I'm writing a script where it detects the last touched surface, and when it moves into the upcoming collider - it should return to it's original rotation values (0, 0, 0). I'm trying to implement this rotational reset using Quaternion.Slerp, but it doesn't seem to work properly. I've tried to fix this problem by myself - but I always hit the same road block over and over, so I'm sharing this problem here in hopes of getting more insight on how to work with this quaternion method. Any help will be greatly appreciated!

# lapis pebble Sorry, my bad - made an edit already

Cool, thanks. You are using Slerp incorrectly which is your problem
Lerp and Slerp are
current = start, end, t where t varies between 0 and 1
you are doing
current = current, end , t where t is basically a constant

#

Also you are only calling it once, it should be in a Coroutine

so what i wanna do is, creating runtime ui item icons. depends of the prefab

like weapons which have sockets to add other stuff like scopes

#

so i want to dynamic genereate ui icons for it.

plucky inlet
#

Also keep in mind, scriptable obejcts on runtime get reset everytime you restart your game/app

frozen maple
#

yes i want to create it. so actually every item has a 3d object. so i want to generate my ui icons dynamicaly

#

yea it doesnt matter when it reset. it just update when load inventory and then only when the item changes

swift falcon
#

Is there a way to determine if an UObject is runtime instantiated? Currently, i am checking the instanceID. If it is negative, then assume it is instantiated. But this gets broken in editor because the instanceID's are changing for each editor session. Not when you swap to the play mode. There are some cases when instanceID does not gets updated too (stays negative). Besides that, localFileIdentifier is not trustable too. It gets updated when you add a component even while playing the game in-editor. So the problem is editor-player.

plucky inlet
frozen maple
#

exactly. i already was able to laod it when i save it as sprite

#

but i though its also possible to have it in memory

#

but seems that this is not working

plucky inlet
#

as long as it is being used, its in memory anyways.

#

I guess, as you are regenerating new screenshots in your code, it just loses the old reference. so you might have some dictionary<itemID, texture> or something to keep track of them

frozen maple
#

thats what i thogougt but without saving it as file i was not able to load it in scriptable. i always get type mismatch

plucky inlet

What mismatch do you get?

I have redone a part of the script to work with Coroutine instead of a delegate, but I still can't properly utilize it (mostly due to my little knowledge of it)
Here is the second revision now: https://gdl.space/senexiguqu.cs

knotty sun
#

so your code is still only executing once

lapis pebble
knotty sun
#

of course, as long as it has a yield inside it

#

you don't think I began coding yesterday do you?

lapis pebble
#

So the yield return null; should be at the end of the while loop?

knotty sun
#

you can easily make it a for loop if you're more comfortable with them

knotty sun
#

and, btw you're still doing
curremt = current, end ,t
not
current = start, end, t

#

also it should be duration / elapsedTime

lapis pebble
#

Nevermind, I fixed already - changed from OnCollisionEnter to OnCollisionExit

knotty sun
#

so you can have multiple coroutines running at the same time

lapis pebble
#

Actually quite smart

#

I have my moments

lapis pebble
#

Gonna keep it in my notes to use for future projects - why don't I think of this??

knotty sun
#

takes years of practice, you'll get there

#

Last question: How do I make the Quaternion.Slerp faster/slower?

knotty sun

in your case. add a multiplier to Time.deltaTime

I have this super annoying behaviour I can't wrap my head around. I instantiate a Prefab with a spawnPositon. Important to me is that the y-axis is 0f. However y is always 1.27f for some odd reason when the GameObject is spawned.

I added some logs and Pos & LocPos both also show y with 1.27f but SpawnPos looks correct.
Why the hell is that y value altered!? The logs are right after the logic so there can't be anything else mutation the transform meanwhile... right?

var spawnPosition = new Vector3(randomX, 0f, randomZ);
var newWorker = Instantiate(workerPrefab, spawnPosition, Quaternion.identity);

Debug.Log(">>> SpawnPos " + spawnPosition);
Debug.Log(">>> Pos " + newWorker.transform.position);
Debug.Log(">>> LocPos " + newWorker.transform.localPosition);

This is the log

>>> SpawnPos (16.22, 0.00, -3.80)
>>> Pos (16.22, 1.27, -3.78)
>>> LocPos (16.22, 1.27, -3.78)

Please somebody explain to me what is going on 😦

but when I try to save it in RAW format it became 64bites 😦

# 
{
    Debug.Log($"Saving a texture with a resolution of {resolution}x{resolution}");
    using (BinaryWriter writer = new BinaryWriter(File.Open(path, FileMode.Create)))
    {
        for (int y = 0; y < resolution; y++)
        {
            for (int x = 0; x < resolution; x++)
            {
                writer.Write(heightMap[y * resolution + x]);
            }
        }
    }
    Debug.Log($"HeightMap saved to {path} in RAW format");
}```
#

This is the code that I use for the RAW format.

#

But when I treat it to show it in the editor and save it as PNG it's fine!

{
    Debug.Log($"Updating preview texture for layer: {generator.currentLayer}");

    // Rigenera la texture corrente e crea una nuova Texture2D per assicurare che sia "pulita"
    Texture2D baseTexture = generator.GetCurrentLayerTexture();

    if (baseTexture != null)
    {
        // Creiamo una nuova texture basata sulla dimensione e formato di baseTexture
        previewTexture = new Texture2D(baseTexture.width, baseTexture.height, baseTexture.format, false);
        previewTexture.SetPixels(baseTexture.GetPixels());
        previewTexture.Apply();

        // Applica i laghi solo se showLakes Γ¨ attivato
        if (showLakes && generator.lakes.IsCreated && generator.lakes.Length > 0)
        {

        }

        // Applica la griglia solo se showGrid Γ¨ attivato
        if (showGrid)
        {
            DrawGrid(previewTexture, generator.gridSize, generator.cellSize);
        }

        Debug.Log($"Preview texture updated for {generator.currentLayer}. Dimensions: {previewTexture.width}x{previewTexture.height}");

    }
    else

    }

    Repaint();
}

        return;
    }

    string path = $"Assets/=== CODE ===/Terrain/Renders/{generator.currentLayer}.png";

    if (path.Length > 0)
    {
        byte[] pngData = previewTexture.EncodeToPNG();
        if (pngData != null)
        {

            AssetDatabase.Refresh();
        }
    }
}``` And then I save it.. and goes smoth as slik

Log heightMap.Length before saving the raw values. Also I'd add a check that heightMap.Length == resolution * resolution otherwise you'll access indices out of bounds which will result in an exception

olive bobcat

Indeed it happen πŸ˜…

I thought I'd convert the array to a texture and then save it. 😁

for commenting is like cooking spices, you don't want too much

If nobody uses it, it rots

That should be motivation enough to write concisely and precisely.

Hey guys. Im making a little portal system between scenes. On a couple of them, whats happening is that the Player(dont destroy on load) is going under the terrain and having really weird placement even tho it is teleporting to the right place.

I've tried using Warp() too, but same behaviour. Here is my code



 public void ChangeZones(ZoneDataSO nextZone)
    {
        PlayerInputHandler.Current.gameObject.SetActive(false);

        StartCoroutine(SceneService.Current.LoadAsActiveScene(nextZone.scene.BuildIndex));
        StartCoroutine(SceneService.Current.UnloadScene(currentGameplayScene.scene.BuildIndex));

        PlayerInputHandler.Current.transform.GetChild(0).position = nextZone.GetSpawnPoint(currentGameplayScene);

        PlayerInputHandler.Current.gameObject.SetActive(true);

        currentGameplayScene = nextZone;

so i have a parent game object with a Circle Collider 2D and the collider was working as expected until i added a child to this game object which has it's own box collider 2d that extends out of the circle... now the box collider is causing collisions to be triggered on the parent game object's OnCollisionEnter2D function..

#

is there a way i can prevent child objects from triggering the parent's OnCollisionEnter2D function?

rigid island
#

iirc no as Rigidbody parent compounds them into one big rigidbody as long as they are colliders

#

maybe if its trigger wont trigger OnCollision but now you have a trigger instead of solid, and could still call OnTrigger

runic pawn
#

ah, i fixed it, i had to add a RigidBody on the the child objects collider

rigid island
#

maybe using Layers you can filter it out

rigid island
runic pawn
#

it was basically using the rigidbody of the parent

rigid island
#

yup thats default rigidbody behavior

So I'm trying to make a script for my game that when a raycast is hitting a players specific body part then the crosshair changes colors but atp it only senses if it hitting the player not if it is hitting a child of it

{
    if (mainCamera == null)
    {
        mainCamera = Camera.main;
    }

    // Get the local player's position and forward direction
    Vector3 playerPosition = mainCamera.transform.position;
    Vector3 playerForward = mainCamera.transform.forward;

    // Calculate the start point of the ray slightly in front of the camera
    Vector3 rayOrigin = playerPosition + playerForward * 1f;

    // Perform a raycast from the adjusted position
    Ray ray = new Ray(rayOrigin, playerForward);
    RaycastHit hit;

    bool isHittingPlayer = false;
    LayerMask mask = LayerMask.GetMask("Client");
    // Check if the ray hits something
    if (Physics.Raycast(ray, out hit, 1000f, mask))
    {
        GameObject theObject = hit.collider.gameObject;

        if (hit.collider.gameObject.CompareTag("Player"))
        {
            isHittingPlayer = true;
            
        }
        



    }

    if (wasHittingPlayer && !isHittingPlayer)
    {
        // The ray was hitting a player before, but not anymore
        ReleaseMouse();
    }

    // Update the previous state
    wasHittingPlayer = isHittingPlayer;
}

if you want to detect from the child you would put the script on the child collider

#

I have a script Called Limb on my limbs

#

it sends message (event) to the LimbManager on root...
Oh nvm I see all you're doing is putting a bool to true instead of doing anything with limb itself

leaden ice
#

because your code requires both

ebon viper
#

yeah

leaden ice
#

you sure? Show a screenshot

ebon viper
#

wait wdym

leaden ice
#

I mean show a screenshot of the inspector of the child object(s) that you're having trouble detecting

ebon viper
#

because the object I am trying to hit has the player tag but the whole object has the Client Layer?

leaden ice
#

Again, can you show screenshots?

rigid island
#

each object has their own layer, it doesn't cascade from the parent object

leaden ice
#

each individual object (parent and child objects included) have their own tags and their own layers

#

they don't inherit from their parents

ebon viper
#

how do I make it check if I am hitting a objects child no matter the scenario

leaden ice
#

I don't know what you mean

#

Does the child object have the correct tag and layer or not?

ebon viper
#

yes

#

it does

leaden ice
#

Can you show a screenshot?

ebon viper
#

i’m eating right now what will a ss do?

leaden ice
#

It will prove that the expected object has the appropriate tag and layer

#

and collider

heya, just a quick question about rendering related stuff- I'm using URP atm and I have a shader graph I'm using for my scene that handles outlines and etc., and right now I have it applied per-material. so everything has a copy of this shader and sets its parameters piecemeal. would it be better performance-wise to have a fullscreen shader apply the outlines and only have each material handle stuff like textures & normals?

I updated the version of Newtonsoft.JSON in my Unity project based on GILES (a map editor made by Unity a while back) and I'm getting the following error

Unable to find a constructor to use for type GILES.Serialization.pb_MeshFilter. A class should either have a default constructor, one constructor with arguments or a constructor marked with the JsonConstructor attribute

Seems to have to do with this code

public class pb_MeshFilter : pb_SerializableObject<MeshFilter>
    {
        public pb_MeshFilter(MeshFilter obj) : base(obj) {}
        
        public pb_MeshFilter(SerializationInfo info, StreamingContext context) : base(info, context) {}

That implement/extends this
     */
    [System.Serializable]
    public class pb_SerializableObject<T> : pb_ISerializable
    {

That implements/extends this

public interface pb_ISerializable : ISerializable
    {
        /// The type of component stored.
        System.Type type { get; set; }

        /// Called after an object is deserialized and constructed to it's base type.
        void ApplyProperties(object obj);

        /// Called before serialization, any properties stoed in the returned dictionary
        /// will be saved and re-applied in ApplyProperties.
        Dictionary<string, object> PopulateSerializableDictionary();
    }

I tried adding [JsonConstructor] but then I get more errors down the line, trying to figure out what changed with that package

leaden ice
#

you should probably mark that field as not serializable or something

elfin tree
#

but seems like it broke with the new newtonsoft.json version

leaden ice
#

and doesn't know how to do deal with that at all

#

You should use its custom serializer to serialize that type

elfin tree
#

yeah but it used to be newtonsoft aswell, so it used to know

#

i'm just not sure where to begin

#

public pb_MeshFilter(SerializationInfo info, StreamingContext context) : base(info, context) {}

#

this is grayed out

#

if I don't add [JsonConstructor] so i thought maybe that was the one it used to use

leaden ice
#

I have no idea honestly

elfin tree
#

yeah it's a tough one even with all the code, hopefuly i can figure it out, ofc this happens after doing all the rest

#

what's weird is some objects with MeshFilter and MeshRenderer will serialize just fine

cosmic rain
elfin tree
#

Cause of a different issue with webgl i had to update the newtonsoft

cosmic rain
#

I don't see how newtonsoft is relevant here though? Looking at the asset source code they don't seem to be using it anywhere.

elfin tree
#

and an old version it seems, cause adding the dependency fixed the platform issue

leaden ice
#

They would have to have implemented some custom serializer for that ISerializable interface then

elfin tree
# leaden ice They would have to have implemented some custom serializer for that ISerializabl...

Did find that

public static pb_ISerializable CreateSerializableObject<T>(T obj)
        {
            if (obj is UnityEngine.Camera)
                return (pb_ISerializable) new pb_CameraComponent( obj as Camera );

            if (obj is UnityEngine.MeshFilter) {
                return (pb_ISerializable) new pb_MeshFilter( obj as MeshFilter );
            }


            if (obj is UnityEngine.MeshCollider) {
                return (pb_ISerializable) new pb_MeshCollider( obj as MeshCollider );
            }
            
            if (obj is UnityEngine.MeshRenderer) {
                return (pb_ISerializable) new pb_MeshRenderer( obj as MeshRenderer );
            }
            

            return new pb_SerializableObject<T>(obj);
        }

And then each pb_Whatever class has some constructor to serialize it manually

#

obj passed seems to be a valid meshfilter (checked in debugger)

cosmic rain
#

Ah ok, I see the dll now

elfin tree
#

the error is when deserializing it seems

anyone know how beamng type softbody works for moving an object?, is force applied to every node in mesh then in every timestep the nodes move and then resolve the change in distances of springs or is every node moved uniformly?

Someone know why I can't ignore layer collisions, even with this : Physics.IgnoreLayerCollision(0, 8);

can i put a reddit link ?

#

i made a post to explaint it

#

sure

kind musk
#

thanks

somber nacelle
kind musk
#

it is what i did before the code, and it don't work

#

i've tried the Physics.IgnoreLayerCollision, but still don't work

somber nacelle
#

prove it, show your layer collision matrix as well as the layer(s) that your colliders are on

kind musk
#

in the project settings ?

somber nacelle
#

that's the only location that the layer collision matrix is located, yes

kind musk
#

not much i know πŸ˜…

rigid island
#

god reddit replies are useless..

somber nacelle
#

so the hidden layer cannot collide with any other layer. if anything is still colliding that means your objects are not on the Hidden layer, or at least their colliders are not

kind musk
#

I've checked, the object is on the "Hidden" Layer, and the player on the "default" layer

#

i've triple checked

somber nacelle
#

show the collider on that layer

rigid island
#

could you also show the inspector while your holding the object

kind musk
#

it is either a Character Conrtoller, either box colliders

somber nacelle
#

we cannot see what layer either of these objects are on in these screenshots

kind musk
somber nacelle
#

this is on the Default layer

kind musk
#

yes

somber nacelle
#

so it is not on the Hidden layer

kind musk
#

i don't want collides between the "Hidden" and "Default" layer

somber nacelle
#

i asked you to show the object on the Hidden layer

kind musk
#

oops

#

coming

somber nacelle
#

and does this object have any children that have colliders?

kind musk
#

but could the "Exclude Layers" can help ?

#

only one "default"

somber nacelle
#

that doesn't have a collider so that doesn't matter

kind musk
#

yep

somber nacelle
#

at this point, unless you secretly screenshot the Physics2D collision matrix, or you have something set in the layer overrides on that most recent collider you've shown, i'd bet the issue has something to do with your networking setup

#

or you have some code changing the layer(s)

kind musk
#

nop

#

but it's probably the network yes :/

#

but i can't find why

somber nacelle
#

ask in the mirror discord if it could be causing this issue

kind musk
#

ok thanks :)

Is there no way to access positions along a spline in Unity? I was hoping to be able to access a point along the curve of a spline using a float or something similar to that

#

But from what I can see I only have access to the vertices themselves, not the interpolated positions between them

rigid island
river kelp
#

Like, built in or do I have to code my own interpolation

#

I can do that, I'm just wondering if I need to or if there's already something built in

rigid island
#

you're talking about the unity splines package ?

#

which methods did you look at

river kelp
#

Well I'm looking at the splines in the spriteShape type

rigid island
#

idk what that is

#

sorry I thought you were talking about another splines

#

should've been more clear πŸ˜›

river kelp
#

Apparently they are the same type of spline

#

(Even though SplineAnimate and such don't accept SpriteShapes from what I can see)

#

a spriteShape contains a normal spline

how do u make shaders in unity 2d i wanna make an icon that needs to dynamically change in real time ive been trying to set up shaders with a material and a sprite renderer but whatever i do it just doesnt wanna show up
is there something i have to enable?

river kelp
#

I'll check out the SplineUtility

cyan musk
rigid island
#

thats only 1 method it has and another

#

that Link is fucking crazy

river kelp
#

Wait, they made a separate type of Spline called "SplineUtility"

#

which is different, for some reason?

#

The datatype of the object I'm getting from the spriteShape is "Spline"

#

Thanks anyway, I'll check out the SplineUtility stuff. I was just looking at stuff on the Spline object itself

rigid island
#

so maybe they're similiar but not the same

#

splines package came out since only a few years

river kelp
#

Hm, I also don't appear to have the same functions available in my SplineUtility

rigid island
#

sucks doesnt seem to have any type of Evaluate method

river kelp
#

That's so strange to me it seems like it'd be the first thing you'd want in a spline

#

like what purpose does a spline serve if you can't access the interpolation

rigid island
#

yeah who knows why these splines are like that, maybe its buried somewhere in typical unity fashion

river kelp
#

Ah, they are in fact not the same spline at all. They are just named the same thing

#

The SpriteShape Spline is a U2D.Spline, and the other Spline is a Splines.Spline

#

Maybe the Unity guys forgot they already had splines (and a spline editor) and decided to reimplement them in this package too

rigid island
#

the new splines uses the mathematics package (eg float3 instead of v3) so it is likely not the same workings, the new one is also integrated into a 3d world

I got a grid of tiles, and I don't want to allow an agent moving in the grid to stop anywhere but the exact center of a tile. So I'm doing a distance check:

    bool IsOverCenterOfTile(Vector3 targetPosition, out Vector3 distance) {
        distance = targetPosition - transform.position;

        // NOTE: Ignoring y-axis for horizontal-only movement
        distance.y = 0;

        return distance.magnitude <= 0.1f;
    }

The problem with this is that the 0.1f isn't the exact center, so agents still spill outside a tile sometimes. However, if I lower this value it becomes too small and the method will instead never return true. This is how the method is used:

void Update() {
    if (!IsOverCenterOfTile(targetTile.transform.position, out Vector3 distance)) {
        MoveToPosition(distance);
    }
}

...
void MoveToPosition(Vector3 position) {
    Vector3 move = speed * Time.deltaTime * position.normalized;
    characterControllerComponent.Move(move);
}

Is there any obvious solution to this problem?

coral scarab
#

I would add a smoothing

#

Like this:

#

!code
void Update() {
if (!IsOverCenterOfTile(targetTile.transform.position, out Vector3 distance)) {
MoveToPosition(distance, Mathf.Clamp(distance.magnitude, 0.1f, 1));
}
}

...
void MoveToPosition(Vector3 position, float moveSpeedMultiplier) {
Vector3 move = moveSpeedMultiplier * speed * Time.deltaTime * position.normalized;
characterControllerComponent.Move(move);
}
!code

#

@sour trench

#

What this does is making the Movement slower when it's close to the target.
You can also change the smootness strength:
MoveToPosition(distance, Mathf.Clamp(distance.magnitude / smoothnessOverDistance, 0.1f, 1));

# humble shoal wouldn't that be just tutorial hell/copying at the start?

To a degree. But many developers never get to the understanding stage, beyond just remembering what steps to take to achieve a certain goal, which is honestly fine for 90% of problem solving. For example, you don't have to understand why (pointB - pointA) gives you the direction from A to B, that's just what you do to get it.

Having the intuition for it is useful for when you're solving novel problems, but 90% of problems are not new and don't require it.

Anyone know how to get the center/origin of the navmeshagent? (my npc's sometimes get stuck, when the navmesh agent driving them is getting out of sync with the character (I'm using updateposition=false, because I get issues with the navmesh agent running into things other wise), and I can see the navmeshagent gizmo is offset relative to the charactercontroller. I can then fix it either disabling and reenabling the navmeshagent, or setting https://docs.unity3d.com/ScriptReference/Physics-autoSyncTransforms.html to true. (saw this on some forum, but docs say its only for backward compatibility). But how do I detect the navmeshagent getting out of sync with the character controller in code? (they're on the same game object)

Ah, is that the main issue you suggest?

#

How would I move it instead?

quaint rock
#

via physics and its rigidbody

fathom rose
#

gotcha

quaint rock
#

if you want to move it just with a transform it should not be a rigidbody

#

so can move it by modifying its velocity, adding forces or with the MovePosition on the rigidbody

fathom rose
#

so i just use Translate then

#

MovePosition sounds like the candidate

quaint rock
#

if its a kinematic rigidbody yes

10 hours trying to pin point the issue, and that's it

Such a niche issue, I thought it had nothing to do with the rigidbody

hasty plinth
#

These are parts of my code, but I think it is sufficient, if not I will send the whole script, no problem

[System.Serializable]
public class City
    {
        public string name;
        public string longitude;
        public string latitude;
        public string population;
        public string country;
    }
[System.Serializable]
public class CityList
    {
        public City[] city; 
    }

public CityList[] cityList = new CityList[26];


print(selectionCountry + cityList[letterInt].city[l].country);
        if(selectionCountry == cityList[letterInt].city[l].country)
        {
            print("passed vibe check");
        }
#

The final print("passed vibe check"); never gets printed

simple egret
#

What is selectionCountry? Where do you change its value?

hasty plinth
#

and the print statement before the "if" returns this

#

JapanJapan

#

that is my issue

#

the values seem to be the same

#

but they don't pass through the if statement as true

leaden ice
simple egret
#

I reiterate, where do you change selectionCountry? Where does the value come from

hasty plinth
hasty plinth
#

cityList[letterInt].city[l].country gets is value from a .csv file

leaden ice
simple egret
#

Log the lengths, loop through all the characters of both strings etc

leaden ice
#

Try @hasty plinth

Debug.Log($"Selection country is [{selectionCountry}] with length {selectionCountry.Length}. The one from the list is [{cityList[letterInt].city[l].country}] with length {cityList[letterInt].city[l].country.Length}");```
hasty plinth
#

Huh, I run

print(selectionCountry.Length.ToString());
        print(cityList[letterInt].city[l].country.Length.ToString());
#

and got 5 and 6

#

So thats it

simple egret
#

There you go, the second is actually Japan

leaden ice
#

And btw instead of that huge switch statement:

        switch (character)
        {
            case 'a':
            letterInt = 0;
            break;
            case 'b':
            letterInt = 1;
            // etc...```
You can just do:
```cs
letterInt = character - 'a';```
@hasty plinth

#

I remembered there was a way to do it by adding on their ascii numbers

#

But I could bother searching it up, so I just copy pasted it arround

#

So thanks a lot

Before moving on, binary search requires your items to be sorted properly!

Afterwards you can either pull all the strings with a bit of LINQ. Or just foreach through the collection, for small collections the lookup speed will be negligible compared to a binary search

Is it possible for a function from a non-mono class to call something that calls unity Destroy,

Yes, UnityEngine.Object.Destroy is static so it can be called from anywhere

and for that class to call another function and finish before the object is destroyed

A little unclear what you mean by this. Destroy actually doesn't immediately destroy objects anyway - they get destroyed at the end of the frame. As for callbacks when an object is destroyed, it depends what you're destroying.

elfin tree
# leaden ice > Is it possible for a function from a non-mono class to call something that cal...

Ah okay that could explain it, I have an issue that if I don't destroy something before I load a new scene, I get an error, yet I destroyed it before and still get the error as if it was not destroyed yet (but destroying it in Start() for example would remove the error)

Is there a clean way for a class that does not inherit monobehavior to wait for destruction?, or maybe I should just make a callback?

leaden ice
#

What are you destroying exactly?

elfin tree
leaden ice
#

Is there a clean way for a class that does not inherit monobehavior to wait for destruction

MonoBehaviour and ScriptableObject are the only custom objects you can call Destroy on

#

destroy isn't relevant for non-Unity objects

#

and both of those allow you to use OnDestroy

elfin tree
#

yeah, well it calls a manager, that Destroys a bunch of monobehaviors that inherit "NonSerializable" an interface i made

leaden ice
#

So can't you use OnDestroy?

#

I don't have a clear picture of your problem

elfin tree
#

you mean OnDestroy cause you'd expect it triggers when changing scenes?

leaden ice
#

OnDestroy will run whenever the object is destroyed, including if it's in a scene that's being unloaded.

elfin tree
#

Yeah, thing is the serialization happens BEFORE the objects are destroyed organically, that's why I force some destruction before the serialization happens

leaden ice
#

I'm not sure I understand why serialization is particularly relevant here

elfin tree
#

Play Test Button Pressed -> ManagerDestroys -> Serialization -> Scene Loads

leaden ice
#

maybe we ought to step back and explain the actual problem more

elfin tree
#

Serialization serializes everything in the scene

leaden ice
#

You haven't actually shared what the error you're getting is yet.

elfin tree
#

I can but it wont help too much

#

Long story short I need to do the following
non-mono calls manager -> manager calls destroy on a list of objects marked as non-serializable -> object is destroyed
and the non-mono class to not trigger the next instruction till that's done

#

alternative is to fix giles serialization but that seems way more complicated

#

one issue always leads to another

leaden ice
#

I mean there's always DestroyImmediate - but I don't really get what the problem is with what's going on now

elfin tree
# leaden ice I mean there's always DestroyImmediate - but I don't really get what the problem...

Yeah it's hard to explain just like that cause there's a lot of variables, I'll try destroy immediate, otherwise I'll try to implement a callback

To give you an idea

    public class pb_TestButton : pb_ToolbarButton {
        public void Test() {
            // Preparations
            LevelEditorServices.LevelEditorManager.CleanUp();
            LevelEditorServices.RampEditor.CleanUp();
            
            // Save pending
            GameServices.SaveService.SavePendingMapAndRecord();
            
            pb_SceneLoader.LoadScene(pb_Scene.SaveLevel(), true);
        }

The line LevelEditorServices.LevelEditorManager.CleanUp(); destroys a bunch of things, yet the instruction pb_Scene.SaveLevel() is running before destruction is complete which causes issues

leaden ice
#

destruction being "complete" is the part I don't understand

#

what specific thing is happening or not happening that is problematic?

#

Is there a Find call finding one of the destroyed objects for example?

elfin tree
#

(and crashes)

leaden ice
#

Well yeah, Destroy does wait until the end of the frame.

You could either wait a frame or just move all those objects elsewhere or create a new root node or whatever

#

there's lots of ways to work around it

elfin tree
#

Yeah, just tested DestroyImmediate and that's exactly what I was looking for

#

Moving could make sense too yeah

Hi, I have an issue with IAP, metadata.localizedPriceString does not return the currency symbol, when I do isoCurrencyCode is show USD but in the console I only see the price as 0.99 and not as $0.99 or USD 0.99

twilit rune
#

public function or property with only set that runs the function?

pliant spade
#

I don't understand what you mean

leaden ice
twilit rune
#

i want to run a function in another script but i'm not sure if i should just make it public or use a property that just runs it

leaden ice
#

There are circumstances in which you might do either one

pliant spade
#

Show the script or any context.

leaden ice
#

So explaining what you're doing would be step 1 to getting any useful help

twilit rune
#

there are no restrictions i want to set, i literally just want to run a certain function in another script

leaden ice
#

Just call a function. It needs to be public of course if you want to call it.

indigo tree
pliant spade
#

Well you can do both.

object.GetComponent<ScriptB>().Function()

or

m_scriptB.Function()

or even a singleton and call is from scriptA

ScriptB.Instance.Function()

twilit rune
#

i've been told to avoid making stuff public if possible, so i'm just a bit confused

somber nacelle
#

if it needs to be accessed from outside of that object then it needs to be public

pliant spade
#

Avoid making stuff public if it's not useful to have it public, only if you need do it

somber nacelle
#

that's like the entire point of making something public

indigo tree
pliant spade
#

It's more of a clean code thing, I will search if that has an impact on anything on the compiler side

For the compiler it will make unnecessary complexity and latency if you make EVERYTHING public, not really an issue but you will die looking at your code before the compiler slow down your game

There are multiple was to go about it. Depending in style, you could make a 2D rig for grass and play animations, but that wouldn’t be a shader.

Also, this is the 2018 version

pliant spade
#

I found this one, but the property has the same description

#

why would unit tests help?

somber nacelle
#

if that is not the documentation for the version you are using, then you should make sure to actually find the correct documentation

indigo tree
pliant spade
# 
/// <summary>
/// Gets the localized price.
/// This is the price formatted with currency symbol.
/// </summary>
/// <value>The localized price string.</value>
public string localizedPriceString { get; internal set; }
somber nacelle
#

i doubt that. are you using unity's In App Purchasing package?

pliant spade
#

Correct, but for the unity version there is no scripting documentation

somber nacelle
pliant spade
#

Not the scripting documentation

somber nacelle
#

if only there were a big old "Scripting API" button on the top bar you could click to get the scripting documentation for that package

pliant spade
#

Maybe you should buy me some eyes!

#

But that does not help that it's the same documentation.

# 
Debug.Log($"ISO CODE: {p.metadata.isoCurrencyCode} LOCALIZED PRICE STRING 
{p.metadata.localizedPriceString}");


ISO CODE: USD LOCALIZED PRICE STRING: 2.99
indigo tree
#

Are you sure localized price string is about symbols?

leaden ice
somber nacelle
#

also is that the documentation for the version you are actually using? because localizedPrice on an older version just shows "The product's price, denominated in the currency indicated by isoCurrencySymbol." which makes no mention of the currency symbol
ah wait, that's the wrong one

pliant spade
#

well it's writen in the documentation, and the other property is without the symbol

image.png
#

@somber nacelle that's the other property

indigo tree
#

I see

pliant spade
#

I'm sure it's a problem in the doc, but since 2018 it has not been "found"?

leaden ice
#

which version are you using

pliant spade
#

unity 2022.3.17f1 and IAP 4.12.2

#

I will test later if that's because i'm in the editor and not on a device too

somber nacelle
#

the documentation is correct. the data populated by those properties comes from the store front you are using so there may be some incorrect setup on that end

pliant spade
#

That's maybe the issue, I'll find out in a few minutes

pliant spade
#

@somber nacelle that was the issue, in the editor no store is here to tell the currency symbol, I suppose it pick the value in the catalog

Alr, thanks for the advice :)

why not just check if the ball's X velocity is a certain amount and the Y velocity is below 1 and if those requirements are met add a force via Y axis

#

to make it go the way you would like

#

i havent used 2d in a while so forgive me if the X or Y placements sounds weird

Only people that deal with VR/XR would be able to answer that, so it's probably better to move to the corresponding channel.

TerrainData.GetAlphamaps is defined as float[,,] which is defined in the docs as... returns A 3D array of floats, where the 3rd dimension represents the mixing weight of each splatmap at each x,y coordinate. What is the range of the third dimension? Is it between 0 and 1? or some other range? Thanks

#

Seeing as it is an alpha value is what makes me assume its between 1 and 0 but would like confirmation please.

how do i view and edit .bundle files?

do i just open them in unity editor?

astral nexus
#

what can I do if I can't plan my codebase BEFORE I start to code?
like, I sit down to uml diagrams/google doc to plan my systems and relations between them - my brain just empty, I simply don't know what to write/think about
but when I sit down to IDE and write code - my brain starts to fart out some code systems, etc.
how can I fix it? I think it's a huge problem, because when "I code as I go" - I have to rewrite A LOT of stuff from scratch and it's drives me crazy, so most of the time I just give up because of overwhelming amounts of rewrites

that refactoring process is what gives you the experience needed to understand how you should structure your code and how to plan it

Can you instantiate objects in start and then raycast against them? I'm doing a simple planet procedural generator and then placing a laser beam which should be exactly between two planets, as shown, but this does not work if I place the planets and the laser building in start for some reason

image.png
#

Is there any weird unity reason that I can't instantiate and then raycast in start or is this a me thing

#

turns out yes it is a weird unity reason

lean sail
gray vessel
#

it's more that I'm doing the building logic by code when usually it is done by the player, so the proc gen stuff hooks into that logic, which needs to raycast because the player could be placing anywhere

#

if that makes sense

#

essentially the laser has an OnPlace() where it raycasts for the planet overhead

#

and I want to simulate that behaviour on start

#

I solved it though

#

I need to run Physics2D.simulate()

#

before placing the buildings

#

painful solution but it's whatever

lean sail
# gray vessel if that makes sense

no, it does not make sense because you mentioned like 5 different features which still doesnt explain why you cannot just use an existing reference to spawned objects. But regardless, .simulate here might be the wrong choice. You might want to sync transforms instead though either solution wont be good performance wise

gray vessel
#

I apologise if the explanation is convoluted

#

It's difficult to abstract

#

I'm trying to say:

  1. Buildings are usually placed by the player, this forces the building to calculate the overhead planet using a raycast
  2. Buildings in this very specific instance must be placed by the procedural generator
  3. I want to simulate the player placement by code, as in, I do not want some separate override for when I place it by code, I want the player building logic and this specific edgecase building logic to be exactly the same
#

But yes, I could in theory create some sort of override to manually place in the target planet and the normal and hit point etc

#

Anyway, it's working now, and the lag spike is lost in the one I already have for procedural generation, so I'm fine with this solution

humble shoal
#

Can someone help me with normalization? I'm kinda confuse

#

Like it's use to make things move at a constant speed and at the same time find direction of an object from another objects perspective

tired elk
#

For example, if you read the input of a controller stick, if you don't care about the tilt amount and only want the direction, you can normalize the input so that the tilt doesn't affect your character movement

humble shoal
#

But why is there length in the input?

tired elk
#

The input goes generally from 0 to 1, and you can use in between values in some situation, like making a difference between walking and running.

#

If I tilt the stick a little bit, my character walks, and if i fully tilt the stick, the character runs.

#

But again, that's an application example.

The problem appears when you put the values as vector components without normalizing

WASD is two separate axes of movement, the (1, 1) is the combined input and you'd lose some information about what the player is pressing if it didn't give you that

The green vector is (1, 1). The blue vector is (1, 0). The green vector is longer than the blue vector. How long? It's the square root of xΒ² + yΒ², which in this case is the square root of 2, 1.414

# humble shoal this calculates ?

The formula I showed calculates the length of the vector. Can you see how the green vector is longer than the blue one? Well, the blue one is obviously length of 1, because you can see it on the X axis, but how much longer is the green one? The formula I showed you tells you how to calculate that.
