I want to eventually cap to 30, but I want to know (as I work on project) if I do/add something that suddenly costs a lot of time

heady iris
#

isn't your texture 300x300

#

that's 90,000

hard viper
#

and I spam so many Debug tools that profiler is normally not super accurate in editor mode

rigid island
heady iris
#

don't you want unique colors?

#

make a HashSet out of it

hard viper
#

ty I'll look into profiler

# hard viper ty I'll look into profiler

You can just profile in editor, the same processes will still be present in the build, so if you see a lag spike due to some code or loading etc that should still be there in build, so if you fix the issue in editor mode that should fix it in the build

#

Also I'm not sure how the "scene" camera works as far as profiler, you'd think that the profiler would be only giving you info based on the Camera in game but i believe that in some cases the scene camera acts as a second camera

#

check if there is an impact on performance by closing the scene panel

#

I knwo this is the case for some functions like "IsInView" or whatever it is for renderers.

#

I'm not sure if its a bug or intended

rigid island
# heady iris make a HashSet out of it

does this look correct

 public static HashSet<Color> ReadPixelColors(this Texture2D texture)
 {
     Color[] cs = texture.GetPixels();
     for (int i = 0; i < cs.Length; i++)
     {
         cs[i].r = cs[i].a;
         cs[i].g = cs[i].a;
         cs[i].b = cs[i].a;
         cs[i].a = 1.0f;
     }
     return cs.ToHashSet();
 }```
# 
  var hash = colorTexture.ReadPixelColors();
  foreach(var h in hash)
  {
      hashedColors.Add(h);
  }``` still white just not 90000 colors

now I remember also why I used GetPixelData 😔 
> Each pixel is a Color struct. GetPixels might be slower than some other texture methods because it converts the format the texture uses into Color. GetPixels also needs to decompress compressed textures, and use memory to store the decompressed area. To get pixel data more quickly, use GetPixelData instead.
> 
> A single call to GetPixels is usually faster than multiple calls to GetPixel, especially for large textures.
> 
> If GetPixels fails, Unity throws an exception. GetPixels might fail if the array contains too much data. Use GetPixelData or GetRawTextureData instead for very large textures.

sometimes super inaccurate

Can someone explain why this code produces this log:

private void _Release(Vector3 position = default, Quaternion rotation = default)
{
    Debug.Log($"{rotation} {rotation == default} {rotation == Quaternion.identity} {rotation == new Quaternion()}");
}

(0.00000, 0.00000, 0.00000, 0.00000) False False False

mellow sigil
#

Because you've passed an invalid quaternion as the parameter

#

Quaternion.identity (and default etc) is (0, 0, 0, 1)

knotty sun
#

no, default is 0,0,0,0 and is invalid and should never be used

hard viper
#

try showing what default is

velvet talon
#

hello i have problem. how to move smoothly objects and not on lines in unity scene?

hard viper
#

i expect default to be all 0

#

but if rotation is default, you might be getting false because == with floats is suck. just a thought

knotty sun
#

no it is false because it must pass a validation test, which it fails

hard viper
#

is that just part of the == for quaternions?

knotty sun
#

for any operation on a Quaternion

hard viper
#

because 0,0,0,0 should be an invalid quaternion

mellow sigil
#

Yes, and two invalid things are not equal to each other

hard viper
#

that’s strange tbh

#

because I would expect it to be i==i&&j==j…

haughty echo
#

Default quaternion and new quaternion struct are both all 0s

hard viper
#

yeah, then it’s the overloaded == operator

#

you can check it btw

#

just check source code for == under quaternion. hopefully it isn’t injected

haughty echo
#

I checked it, I think something else is going on, it's just a comparison of the 4 component floats

knotty sun
#

it's not, the code is very clear, only valid Qaternions allowed for operators

I know that you use Unity Events by += subscribing and -= unsubscribing functions to them. But, it seems I cannot find a function to unsubscribe everything from the Event?
I'm making a modal window for my UI, I want to set it up so that it hands in my main UI object, and various situations that require an y\n reaction from the player will activate that UI object and subscribe to one of it's Events. I then want to ensure that at no time no matter what no more than a single subscriber for that event exists and the past subs wouldn't linger, so in the function that gets called when a button in the modal window is pressed I want to call Invoke on the appropriate event, and then unsubscribe all subscribers from it:

        public event Action PressedOk;
        public event Action PressedCancel;

        public void CallbackOk()
        {
            PressedOk?.Invoke();
            PressedOk?.UnsubscribeAll(); // This one is missing
            this.gameObject.SetActive(false);
        }

        public void CallbackCancel()
        {
            PressedCancel?.Invoke();
            PressedCancel?.UnsubscribeAll(); // This one is missing
            this.gameObject.SetActive(false);
        }

I suspect if that function is missing, my idea for how modal popup should work isn't exactly a correct one?

# sage latch `RemoveAllListeners`

No such function I can find, however I found a similarly sounding one, would that be correct? Not sure why it requires two arguments though, based on the description at the Microsoft docs, I think I should pass the same into both anyway.
Action.RemoveAll(PressedOk, PressedOk);

for a normal event just set it to null

Bitwise operation

In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor. Most bitwise operations are presented as two-operand inst...

I want to use for other stuff too but mainly to see if what the RT camera is looking at is lit up by lights

hexed pecan

Because that would make it all white if it has full alpha

rigid island

do i need that loop at all?

thanks for making me notice stupid mistake..

I think the color format has something to do with it but idk how ton change it

#

here are the differences in format

This looks like it would match RGB8

I can't find info about RGB8 but I guess it's 8 bits per channel

deft spear
#

Im trying to block clicks under gui button using if (EventSystem.current.IsPointerOverGameObject()) return;, but this also blocks clicks on terrain, I think because my canvas covers the entire screen?

hexed pecan

Or maybe it is 3+3+2.. Idk

delicate olive

I tried this manual copy didn't work

# 
 public static Texture2D ChangeFormat(this Texture2D oldTexture, TextureFormat newFormat, out Color32[] color)

     Texture2D newTex = new Texture2D(oldTexture.width, oldTexture.height, newFormat, false);
     Color32[] cs = oldTexture.GetPixels32();
     color = cs;
     newTex.SetPixels32(cs);
     newTex.Apply();
     return newTex;
 }```
#

ir just copies it black

deft spear
#

@delicate oliveWill this check not stop me from clicking on my buildings etc. too?

delicate olive

I would try something that has 8 bits per channel

# 
        if (Input.GetMouseButtonDown(0)) {
            if (EventSystem.current.IsPointerOverGameObject()) return;

Makes me unable to click on anything else but UI

#

My buildings and units are in 3d

Logically it should work, both have 8 bits per channel and 4 channels

# hexed pecan <@968604165150507078> See my edit

its not black but now im having the same color than when I did ReadPixelData with original format on new texture```cs

       //pixelData32 = newTex.GetPixelData<Color32>(0);

       // for (int i = 0; i < pixelData32.Length; i++)
       // {
       //     if (!colorsNewTexture.Contains(pixelData32[i]))

To find the UI blocking the view, you could do something like this:

    public GameObject GetGameObjectOverPointer()
    {
        var lastPointer = GetLastPointerEventData(-1);

        if (lastPointer != null)
        {
            return lastPointer.pointerCurrentRaycast.gameObject;
        }

        return null;
    }

    // Debug the logic using log statements to for example print out the name of the gameobject if it isn't null

Slight correction; to use the protected GetLastPointerEventData() function, the class needs to derive from StandaloneInputModule

deft spear
#

How is this not managed by Unity by default

delicate olive
lean sail
#

you can see what UI is blocking with the event system panel already

delicate olive
lean sail
#

pointerEnter

deft spear
#

if (Input.GetMouseButtonDown(0)) {
if (EventSystem.current.IsPointerOverGameObject()) Debug.Log("Clicked on GUI");

This fires on EVERYWHERE I click

delicate olive
lean sail
delicate olive
#

Always looked at the "First Selected" field on the EventSystem component and it was always null so

deft spear
#

What panel?

lean sail
delicate olive
lean sail
#

also you have to be in play mode

deft spear
#

Looks empty to me

lean sail
#

🤔 not really sure why you dont see anything tbh

delicate olive
#

It should also show the object in the inspector when it is in Debug mode

deft spear
delicate olive
#

Where's your standalone input module? I have it here

image.png
deft spear
#

I dont have one

delicate olive
#

Oh you must be using the new input system then

deft spear
#

Its converted

delicate olive
#

So it must be detecting somethign

deft spear
#

Ya it detects my gui buttons

delicate olive
#

But does "selected" mean "hovering" or does it mean you've clicked the button?

deft spear
#

This option also clears the selection when clicking on terrain

#

It always says Selected:

delicate olive
#

What if you just try disabling the canvas and see if you can click the 3D objects

deft spear
#

I can not

delicate olive
#

Then if you can, work down the canvas hierarchy object by object until you find the culprit

#

So it's not the canvas

#

Did it register input b4?

deft spear
#

Ya, if I remove the eventsystem check I can run my raycast

# 
void Update()
{
    
    if (Input.GetMouseButtonDown(0)) {
        // if (EventSystem.current.IsPointerOverGameObject()) Debug.Log("Clicked on GUI");
        Destroy(_placedMouseCursor);
        ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        if (Physics.Raycast(ray, out hit, Mathf.Infinity, layerMask)) { 
            Debug.DrawLine(transform.position, hit.point, Color.red);
            _placedMouseCursor = Instantiate(mouseCursor, hit.point, Quaternion.identity);
            MoveAgent(agent);
        }

    }
}
delicate olive
#

Is the EventSystem a part of the new input system? Because you're using the new system and if it's not then you shouldn't even be doing the check with the old system

#

I haven't used the new system so I dunno

deft spear
#

No idea

#

Maybe its not

delicate olive
#

ChatGPT says it is part of the old system

#

and that there is no equivalent in the new system

deft spear
#

Or well, the input system module is converted under Event System

delicate olive
deft spear
#

Im on 2023

#

I have not configured anything in the input system gui tho

delicate olive
#

I guess we're at a dead end (at least on my part) because I have never used the new input system; maybe people in #🖱️┃input-system are more knowledgeable with this

real ivy
#

hi!

#

i want to have a list of scritps to be add on the object when it is instantiated, how can i do that?

delicate olive
real ivy
#

it makes sense, but what i don't know is the type i should declare the list

delicate olive
#

MonoBehaviour..?

knotty sun
#

List<System.Type>

real ivy
#

let me try

lean sail
real ivy
delicate olive
knotty sun
#

no, but it's your list so you control what goes in it

delicate olive
#

Yeah but he wanted to use the list in a function that adds components to an object

knotty sun
#

yeah, so?

delicate olive
#

Using System.Type in the list would not allow for that functionality..

knotty sun
#

of course it would

lean sail
#

you can cast

delicate olive
#

Yeah, but why cast when you can just directly declare it as a list of MonoBehaviours/Components?

knotty sun
#

no need to cast Addcomponent has a Type override

delicate olive
knotty sun
#

no

lean sail
#

oh it does have an override

real ivy
#

i can't add the script to the list on the inspector

#

(using the system.type)

knotty sun
#

no, System.Type is not serializable, but then you never mentioned that

delicate olive
real ivy
real ivy
delicate olive
#

Also, do you really need to use AddComponent? You could consider methods like prefabs

real ivy
delicate olive
real ivy
#

how do you sugest me to do?

#

the addcomponent was my first idea

lean sail
#

this does sound weird to be adding a list of components, but if you do continue like this then you probably do want to use Component instead, or else you wont be able to add rigidbody or similar stuff

delicate olive
#

Then I would use a prefab 100%

real ivy
#

i have a bullet and want to add modifiers to it

#

this is a prototype btw so i can test all the ideas

knotty sun
delicate olive
# real ivy i have a bullet and want to add modifiers to it

Idk, this may be a great way for that as it uses composition (which is good for modularity), but another approach would be to just have one class like BulletModifiers attached to the bullet and access that when you want to add effects to it

real ivy
#

give me a minute

lean sail
# real ivy i have a bullet and want to add modifiers to it

If you need this to be 100% modular, like the user can fully customize what a bullet can do then I'd just store the modifiers in one class and maybe have the functionality on a scriptable object.
If it's a difference of selecting between 5 possible bullets, just make prefabs

hexed pecan
delicate olive
lean sail
#

It's definitely not the best way, just a quick way to test

delicate olive
#

And when refactoring for example, file name changes are pretty common so

delicate olive
real ivy
#

yeah it gives me compile error for being obsolete

#

but i think it is possible to convert from string to type

knotty sun
#

yes, using Reflection

lean sail
#

Is that really a compile error? I thought itd just be a warning

hexed pecan
#

It does show up as a compile error in VSCode though

real ivy
lean sail
lean sail
real ivy
#

now i just need to do it for the list

#

do this have any significant performance impact?

hexed pecan
#

You could also make a dictionary that maps an enum value to a type

real ivy
#

that's cool

#

i liked the string aproach

real ivy
lean sail
real ivy
#

i think i can do something

#

i can just have the list of types ifself

#

but now it works, thank you all

Is it possible to use the netcdf library in C# to play simulations in Unity or does anyone know how to do this in Unity =) ? Hey guys I currently have a C++ project where I simulate tsunami waves 2 dimensionally. To save the values of the waves I use the netcdf,zlib , hdf5 library. The calculated values are then saved in this .nc file and I can then display the values in a program "Paraview", i.e. play the time steps and then see a simulation. My goal now is to bring everything into Unity and play my simulations directly in Unity.

you don't have to track the player with cinemachine. it's meant to control your camera

My object isnt moving

hexed pecan
long saffron
#

testing it

hexed pecan
#

That will practically only move it once, 2 units right of the starting position

long saffron
#

but it stays in place, not sure if its jittering

hexed pecan
#

Then gameMode is probably not 1

#

Or you have something else changing its transform, like an animator with root motion

long saffron
#

its just a sphere and i put a debug statement there and its being called

#

I instantiated it but I call starting position after that

#

It says that it moved once and then stalls there

hexed pecan
hexed pecan
long saffron
#

im testing it so yes for now

hexed pecan
#

You are setting the pos to startingPosition + offset, neither of those values are changing so it will stay in place

#

You can do transform.position + offset if you want it to constantly move

long saffron
#

but its in the update

hexed pecan
#

That will move it 2 units every frame though, so you want to multiply it with deltaTime to make it correctly scale to framerate

hexed pecan
long saffron

i put += and then it worked

In Unity's version it used to be IsAssignableFrom, just reverse the arguments

much more confusing way of doing it, so they flipped it thank god

I see that. but I see IsAssignableTo in the source. I just can't access it for some reason. it says no such method found in System.Type

Looking into Additive Scenes currently, It doesn't look like you can simply load an additive scene in and place it at a specific position natively from what I can tell.. I have some ideas of how to position the additive scenes in the active scene but it's a hacky solution.

How do others work with them generally?

spring creek
gaunt wren
#

right, that makes sense. So you have build these scenes with specific coordinates in mind to ensure scenes don't overlap each other.

in my case, it is for level chunks. Probably see if Prefabs are just as viable

        //Parent.Animator.SetInteger("State", (int)ActionState.hit);
        Controllable = false;
        gameObject.layer = 9;
        Debug.Log("Hurtbox: " + Hurtbox.enabled);

    }```
#

or well

#

the debug returns false, but it's still enabled on the inspector, and when I check it here it returns true

void endInvincibility()
 {
     Debug.Log("Hurtbox: " + Hurtbox.enabled);
     Hurtbox.enabled = true;
     ChangeEffect(EffectState.normal);
     animator.SetInteger("Effect", (int)effect);
     gameObject.layer = 0;

no other part of the game even references the hurtbox

I've extracted a function in one of my scripts as an extension abstract generic method, because I needed to do same thing in another script, and it for some reason doesn't work like that - even in the initial object I plucked it from. What might be the problem?

            Transform currentParent = p;

Isn't using the Log function a debug?

lean sail
thin hollow

I use Rider, and while it activates the debug mode in unity, it is completely empty:

not really sure how rider debugger works tbh

thin hollow
#

Oh, I needed to add a red dot to the line of the code...

Ok, I can see what's happening now, it seems like the problem is that the for Loop runs only for two iterations no matter what. Even if I just hardcode 5 iterations, for (int i = 0; i < 5; i++), it checks the current transform, the parent of that transform, and then seemingly stops - next breakpoint happens for script on another object.

spring creek
#

@thin hollow So, I am only just coming in to this, but I see you have two conditions that check if the object is null, and else it breaks.
Could the object simply NOT be null? The first if statement sets it to something currentParent is not null

for (int i = 0; i < hierarchyDepth; i++)
{
    if (obj == null && currentParent != null)
      obj = currentParent.GetComponent<T>();

    if (obj == null)
        currentParent = currentParent.parent;
    else break;
}
#

Were one of those if statements supposed to say if obj != null?

#

I would use the debugger to on the obj = currentParent line

thin hollow
rigid sleet
#

am I missing something? Whats the i variable here for?


for (int i = 0; i < hierarchyDepth; i++)
            {
                if (obj == null && currentParent != null)
                    obj = currentParent.GetComponent<T>();

                if (obj == null)
                    currentParent = currentParent.parent;
                else break;
            }
#

I dont see you using it anywhere

#

you arent iterating over the transform hierarchy anywhere

thin hollow
rigid sleet
#

okay so what are you exactly iterating over here

spring creek
rigid sleet
#

just i times over the direct parent?

#

just trying to understand the goal here

#

okay I got it, 1 sec

spring creek
#

I read it as a deep hierarchy. Many levels of children, grandchildren, etc.
It iteratively checks up the chain for a given generic component

rigid sleet
#

yep yep got it, I was confused due to how this was written, a lot of the checks seem a bit redundant

thin hollow
# rigid sleet just i times over the direct parent?

The way it supposed to iterate is "try to get component from the current transform, if it returns null, set current transform to the current transform's parent, repeat until component is found or loop ran out"

rigid sleet
#

hmm yeah it seems very sane, let me plop this on an empty project and see if I can get it working

#

you dont need to check if the object you are passing is null, if its null then it means you got into a null parent aka top hierarchy object so you can do something like this instead


            Transform currentParent = p;
            T obj = null;
            i = 0;
            for (int i = 0; i < hierarchyDepth; i++)
                obj = currentParent.GetComponent<T>();
                if (obj == null){
                    currentParent = currentParent.parent;
                    if (currentParent == null) break; //If the parent is null then we stop traversing the hierarchy
                }
            }
#

but yeah doesnt fundamentally change the code, gimme a minute to get unity running

thin hollow
#

Huh, weirder, I commented out else break;, and now it completes the loop. Upside - it works, downside - I think this way it doesn't stop and runs out the remaining loops even after object was found. A little, but waste of resources. Not ideal, but I don't think I will have hierarchies deeper than 5 or 6, so...
Still, why it does this?

rigid sleet
#

oh, okay i see an issue

#

yeah your code will always return itself

thin hollow
#

what do you mean?

rigid sleet
#

I just called your code and it worked on my end

#

but it returned itself

#

if for some reason the class you are running this from also has the component you are looking for it will return itself

thin hollow
#

I call it in this way:
ICollisionTriggerReceiver parentInterface = transform.FindInParents<ICollisionTriggerReceiver>(5);

#

And, no, the class I run this from doesn't have ICollisionTriggerReceiver interface inheritance, it's only on the parent.

rigid sleet
#

hmm yup your code doesnt find the object on my end

thin hollow
#

I thought maybe the issue is due to ambiguity of ifs with those missing parenthises, but with both

            for (int i = 0; i < 5; i++)
            {
                if (obj == null)
                {
                    obj = currentParent?.GetComponent<T>();

                    if (obj == null)
                        currentParent = currentParent.parent;
                    else break;
                }
            }

and

            for (int i = 0; i < 5; i++)
            {
                if (obj == null)
                {
                    obj = currentParent?.GetComponent<T>();
                }

                if (obj == null)
                {
                    currentParent = currentParent.parent;
                }
               else break;
            }

it breaks again. =\

rigid sleet
#

there is something really weird going on

# 

for (int i = 0; i < hierarchyDepth; i++)
        {
            Debug.Log($"Checking for Component on: {currentParent.name}");
            obj = currentParent.GetComponent<T>();
            Debug.Log($"Obj is null?: {obj == null}");
            if (obj == null)
            {
                currentParent = currentParent.parent;
                if (currentParent == null) break;
            }
        }
#

ohhhh nvm

#

this works for me


public static T FindInParents<T>(this Transform p, int hierarchyDepth = 5) where T : class
    {
        Debug.Log($"Running");
        Transform currentParent = p;
        T obj = null;
        for (int i = 0; i < hierarchyDepth; i++)
        {
            Debug.Log($"Checking for Component on: {currentParent.name}");
            obj = currentParent.GetComponent<T>();
            Debug.Log($"Obj is null?: {obj == null}");
            if (obj == null)
            {
                currentParent = currentParent.parent;
                if (currentParent == null) break;
            }
        }

        if (obj == null)
        {
            Debug.LogError("No parent has " + typeof(T).FullName + " component");
        }
        return obj;
    }
thin hollow
#

Hmm, you think its because of the daddy parent issues?
I think your code will not find anything if the desired component is from the first child of the object, instead of the object itself. I think this code trying to find the first encountered component instead of trying to grab one from the topmost parent has more potential usage in the future .

rigid sleet
#

yeah this grab the first one

#

from bottom to top

#

from the parents

thin hollow
#

Hm, yeah, your version seems to work even with the "break" that, well, breaked it before. Weird >_<

            for (int i = 0; i < 5; i++)
            {
                obj = currentParent?.GetComponent<T>();

                if (obj == null)
                {
                    currentParent = currentParent.parent;
                    if (currentParent == null) break;
                }
                else break;
            }
rigid sleet
#

just to make sure, you want a version of this script that returns the last ocurrence of the class right?

thin hollow
#

no, the first it gets. For the last I think I can always crawl to the topmost parent with iteration and call "findComponentInChildren()" from there.

rigid sleet
#

gotcha gotcha

#

then yeah that should work for you then, let me do a double check with another class just to be sure

#

I think I am finding a unity bug here

#

If I check for a rigid body class

#

it breaks

#

for some reason the returned obj is not null

#

but its null when checked

#

bizarre

#

it only happens when looking for a rigidbody haha

#

Yeah i think this is some bizarre unity issue, this doesnt work for any UnityEngine class

#

oh

#

obj == null

#

yeah this is wrong

#

you cannot do that for Generic types

somber pulsar
#

Does anyone wanna be a playtester for a unity project?

rigid sleet
#

@thin hollow okay this is the fixed version

# 

public static T FindInParents<T>(this Transform p, int hierarchyDepth = 5) where T : class
    {
        Transform currentParent = p;
        T obj = null;
        for (int i = 0; i < hierarchyDepth; i++)
        {
            obj = currentParent.GetComponent<T>();
            if (obj == null || obj.Equals(null))
            {
                currentParent = currentParent.parent;
                if (currentParent == null) break;
            }
        }

        if (obj == null || obj.Equals(null))
        {
            Debug.LogError("No parent has " + typeof(T).FullName + " component");
        }
        return obj;
    }
#

it was indeed some unity fuckery

#

You cannot directly check for obj == null

#

because it is not a Unity type

#

this checks both cases, as a system object and as a unity object

The whole idea of finding a component in a parent to me is very bizarre too

#

If you have a sane architecture you almost never wanna do that

plucky anchor
#

so because I couldn't reference the thing I wanted dirrectly, I tried to workaround it and failed

rigid sleet
#

Talking about the other code not yours hehe

thin hollow
# rigid sleet The whole idea of finding a component in a parent to me is very bizarre too

My first case for which I initially thought it up: I needed to have several trigger colliders on one prefab and to also discern between the triggering of different colliders (It's an object that does different things based on from which direction player have come from, basically, and directions aren't aligned with the coordinate grid). So I implemented interface for the prefab object that receives typical OnTriggerEnter function analogs, but with additional references to what child they were triggered from. I didn't want to hardcode in parent-child structure (what if I'll want to reuse this in another prefab with a different amount of children?), so I made this code so that child objects would seek the interface in parent on their own.

lean sail

yea but not really sure why your ide doesnt show it tbh

It might be a Visual Studio Code Editor issue, I will look into that. Thank you for the help either way 👍

rigid sleet
#

If you want a pro tip about interfaces in Unity @thin hollow

#

If you are gonna have any kind of serialization and prefabs you should try not using them lol

#

You are gonna have a lot of headaches

#

Nowadays I use virtual methods and avoid the issues down the road

thin hollow
#

I have my entire level design philosophy built around basic "triggerInterface" with which different classes can activate any other object you reference to them in the Inspector....

rigid sleet
#

Nested serialization (prefabs and prefabs of prefabs) really mess the references up

#

Food for thought it might not be something that happens to you hehe

thin hollow
#

All of my references are set once in the editor and won't change during gameplay, so they aren't being serialized.
Though, for NPCs, that's not true, so that's an important warning to look forward to, thanks again!

#

Would probably need to serialize GUIDs instead of direct references, and on loading search for objects with that GUID to reassign the references...

rigid sleet
#

Btw setting stuff in the editor is serialization

#

In fact that’s a really easy way to break interface serialization, nested prefabs completely break interface references and you have to assign them at the top level prefab

thin hollow
#

Wait, but if it's nested serialization that messes references up, how not using interfaces will help to avoid this?

rigid sleet
#

That doesn’t happen to normal references

#

How are you referencing interfaces in the editor btw?

thin hollow
rigid sleet
#

You can’t really do that by default yeah which is a big downside

#

Using something like Odin Inspector you can reference them directly and that’s when things break

thin hollow
#

Ah, well, that's easy then, I can't use Odin cuz I can't pay for it. XD

why on other projects it worked with just SceneManager.LoadScene("Game 1");, but now i need to do SceneManager.LoadScene("Project Data/Game/Scenes/Game 1"); Also in this case if i were to check for scene name, should i check for the full path or just Game 1?

For people new to async/await approach,
Let's say we have a method:

public async Task RenameUser(string userId, string newName) {
throw new NotRegisteredException();
}

What will the return type look like and how can the method caller handle this exception?

craggy veldt
#

you'd want Task<T> to return something

async Task<bool> AsyncFoo()
{
  try
  {
    await Task.Delay(TimeSpan.FromSeconds(5), myTokenSource.Token);
  }
  catch(OperationCancelledException)
  {
      //Do your thing when token was cancelled
  }
  return true;
}

In the Unity build how can I make it detect display 1 and display 2 ?

craggy veldt
stoic ledge
stoic ledge
craggy veldt
#

here from the docs

stoic ledge
#

yep, exactly

#

By return type I mean will Exception be thrown upwards the stack or will it be "Task" with IsFaulted == true.
But I got it clear already, thank you.

craggy veldt
#

you can always check them via Task.Result

#

if you're wrapping your logic around the tokensource cancellation then just check the token instead

#

also, it is a good practice to throw in async/await when cancelling sources

cosmic rain
#

Unless you await it I guess🤔

#

Always confusing business with the async throws

merry stream
#

so I'm watching a tutorial on an inventory system using script able objects. is it always bad to change script able objects at runtime or is it fine to use in an inventory? would making an onapplicaitonQuit function to clear the inventory work?

leaden ice
merry stream
#

I understand that changes to them persist but could you elaborate? i'm just trying to learn best practices for unity dev and overall coding architecture. I feel that many tutorials overlook this to simplify everything like making everything public.

leaden ice
#

Under all other circumstances, changes will not persist

merry stream
#

so why have I heard that they should only be used to store data that won't be changed? Is it acceptable to use it for an inventory?

leaden ice
#

It's acceptable to use for an inventory if you understand the nuances and the behavior that will come from how you are using it

#

Obviously the difference of serialized vs non serialized data also comes into play

merry stream
#

how so?

leaden ice
#

How not so?

#

Serialization is central to that whole persistence issue

#

Since only serialized data can possibly be persisted by the engine

#

A lot of people use SOs as a convenient referencable object in the editor.

You could do that and have a non serialized inventory on it and there's no risk of persistent changes

#

So it really just depends on exactly the details of your usage

latent latch
#

SOs can be used many ways, but the only reason I don't write to them is because plain c# objects satisfy my requirements already.

#

it's actually fine if you want to dupe data to write to

merry stream
#

so you would instead make a inventory singleton?

merry stream
leaden ice
latent latch
#

I usually just make them as a plain c# object, but if you've a one player game where you've a single inventory I could see some use.

so what does adding serializable do?

Hello, I'm following Jerry Tessendorf paper on simulating water. I'm a bit confused with complex vectors ("I hope that's how they called"). Anyways, I have formula for normal maps (attached picture). The issue is that I don't understand how to express i*k (the first part) , where k is vector with both real parts. Any, help would be helpful!!!!

Screenshot_20231228-124746_Samsung_Notes.jpg
leaden ice
#

You'd have to create a data type to represent complex numbers

#

You could make a ComplexVector3 type to represent complex vectors

#

It may consist of 3 complex numbers

fair dew
#

I know that when u express real number in complex plain you get vector2, first part real and the second imaginary. So, now I would need vector 3 where 2 first numbers are real and last one is imaginary? Or do Ineed vector4?

#

K is vector2

leaden ice
#

Vector2 is a cop out

#

Make an actual ComplexNumber type

#

You could use Vector2 inside but you need to define the interactions properly because you can't just do operations on Vector2 like normal.

fair dew
#

Cop out?

leaden ice
#

It's lazy

#

It just happens to be a struct that holds two numbers

#

So it CAN represent a complex number

#

But it's not going to solve any problems for you

fervent furnace
#

you have to define the multiplication operator for imaginary number
you can use three vector2 btw, but you cant overload the operators of vector2

leaden ice
#

I think it would be much clearer and cleaner to make a custom Complex struct

#

And define all your operations/functions/operators etc as necessary

fair dew
#

I'm a bit more confused with the mathimatical part, the programming part is clear. So if I have real number: 3, I can express it as 3 + 0i. How would it work with complex vector?

fervent furnace
#

and you need to make you own Pow of complex number (e^(real part))*eular formula iirc

fair dew
proud fossil
#

what executes first FixedUpdate or Update

mental rover
proud fossil
#

thx

mental rover
fair dew
#

Oh you ment for vector

mental rover
#

to stop things getting very messy I'd go with PraetorBlue's suggestion of implementing that complex type yourself and ensuring all elementary operations are what you want

fair dew
#

But how we go from vector2 with both real parts to 2x vector3 in complex plain?

mental rover
#

a complex number is just a number

#

you can think of it as a vector of two parts, but conceptually it's just a number

fair dew
#

So, if we have 2 real numbers how we end up with 3 real numbers?

proud fossil
#

and i still dont understand the tick thing

mental rover
fair dew
fervent furnace
#

you can have a custom struct

public struct A{
  public static operator XXXXX.....
}
```then you can have a Vector of A
```cs
public struct Vector2A{
  public A x,y;
}
mental rover
fervent furnace
#

(just like what unity names its Vector2Int...)

#

they replace the float to int

fair dew
#

Anyways, I will try calculating this part twice first I will calculate for k.xi... and then for k.yi... As this will give me tangent and bitangent. @mental rover

if it works it works right

I'm making a simple game where you bartend and talk to people. I was wondering how I should manage sequence of events like when you finish making a drink or once you talked to NPC 1 then NPC2 comes over and starts talking to NPC 1.

#

State machine? Like stay in that state until conditions are met then move on to the next state and repeat?

#

Or maybe an event system, like when something is done, tell some manager class and set something to true. Or a mix of both?

#

What would anyone recommend?

mental rover
#

trimmed of a lot of boilerplate to the point it's just an iterator, since likely it just needs to be in the form A -> B -> C -> D

turbid surge
#

Story narrative yep, and okay yes that feels right. Coroutine state machine that waits until conditions are met to move on. Then when it moves on the next state it runs all the stuff it needs (timeline cutscenes, other stuff,etc.) then awaits to move on til the next conditions are met (served X drinks, talked to NPC about X).

So it seems to be impossible to get Cinemachine to work in unity 5.6, is there a good alternative that works?

rigid island
#

why are you using 5.6 anyway

ocean river
#

There are specific builds for N3DS, which are not supported anymore

#

but its the only way to unity for n3ds

#

anyways,
cinemachine for 5.6 or alternatives?

rigid island
#

Not sure I came into unity when cinemachine was already bought off, so never had to use anything else :\

spring creek
# ocean river anyways, cinemachine for 5.6 or alternatives?

Cinemachine was added in version 2018.1 it looks like (from the manual)

There isn't really an alternative afaik. Maybe you can see if early versions of the standalone cinemachine (pre-unity purchase) works

Might be something really old from the asset store, but I have no idea

playables

#

it uses playables back in 1.0, i just checked

#

there isnt a way to exactly use playables in five like in 2017 right

knotty sun
#

you can use 2017 for 3DS development

ocean river
#

yeah but

#

its buggy as hell

#

afaik the lastest ever released n3ds was on five.six.six

#

sorry five and six keys are broken

knotty sun
#

2017.2.5

#

but you are right 5.6 was more stable

ocean river
#

some smart guy: it's better to keep on 5.6, 2017 is unstable because they haven't finish it, there is a lot of unknown issue and memory leak + the very last version of unity for 3ds released was on 5.6

#

i have a version from 2020 which is five.six so hes right

rigid island
#

just word of mouth

ocean river
#

hes some guy called ynox working on that sonic unleashed for 3ds, not sure if i should

rigid island
#

I also love the whole "trustmebro" on the internet

ocean river
#

i could try it though

rigid island
#

just try it and test?

knotty sun
#

I can tell you he is wrong, I could screenshot the developers download page showing the SDK version but I won't (NDA)

ocean river
#

aaaaaa i wish i had such an 3ds account

#

they dont allow nda 3ds anymore

#

so much stuff 'd be easier

#

just asking, but,

#

where can i even get this 2017

#

i only have 5.6.5 and 5.6.6

knotty sun
ocean river
#

its not a public version

#

it was distributed on nintendo dev

#

but yeah its not downloadable anymore

knotty sun
#

you wont get that if you're not a reg. developer

mmmmmhmm

sad

thanks for the advice though

weird question:
is it possible to write on the same line a <summary> of a var/function/... ?
something like c# /* <summary> is player on the ground </summary>*/ private bool _isGrounded = true;

#

i prefer in one line rather than above

same logic as

[Tooltip("Zipline")] [SerializeField] private LayerMask _ziplineLayerMask;

also never use GameObject.Find

why

cause its painfully slow , awful and error prone

it works fine?

ok use then ifc

you seem to know better UnityChanLOL

swift falcon

how can I access a child of an obj then

did you look it up should be first result

though you would want to use Components direclty with GetComponentInChildren

but theres still a problem, AnswerObj doesnt exist

rigid island

another script

and is it attached on an object yes?

its value is that script

wat?

and yes the script is attached to an obj

rigid island

and is the object Enabled ?

swift falcon

gimme a sec

cause thats prob why its null

swift falcon

funny thing is that this error occurs when theres no answer, so I think yes

error

#

i meant

rigid island
#

make sure no other copeis are there

swift falcon
rigid island
swift falcon
#

its disabled at the beginning, i click a button and i create an answer (4 max)

#

but this error appears when i dont create an answer and i switch to the next question

#

so i cant put it on an object and dont disable it at all, would be even more messy

#

but i can check if that variable is not NULL, right?

#

it works

rigid island
swift falcon
#

i fixed it

swift falcon
rigid island
#

why would it be messy putting Answers.cs on a gameobject that doesn't disable ?

swift falcon
#

its answer.cs, trust me it makes more sense because it runs on every answer

rigid island
swift falcon
#

runs on multiple objects

rigid island
#

the whole system is brittle

#

why are you even using Update() instead of events..

swift falcon
#

when you are making a quiz in kahoot dont you want your question to have multiple answers, correct or incorrect that you can choose from

round violet
rigid island
#

also GetComponent in Update is mega cringe and inefficient

swift falcon
swift falcon
rigid island
#

but doing things Event based in probably smarter.

#

Learn about events

#

you're already using them for buttons, no reason to do all this in update

Anyone familiar with orthogonal projection? I have the fallowing code, and it isn't giving the values I would assume.

        public static Vector2 ProjectOntoLine(this Vector2 v, Vector2 lineDirection) {

            Vector2 normalizedLineDirection = lineDirection.normalized;

            // Calculate the scalar projection
            float scalarProjection = Vector2.Dot(v, normalizedLineDirection);

            // Calculate the projection onto the line

I want to move my player as realistically as possible by using physics, because I want to be able to accumulate momentum by wall jumping, hitting an enemy etc. but I don’t know what the right way to do that is? I tried using AddForce() but that makes the player very slippery, and I still want the game to feel snappy

Anyone know how to help?

Alright finally done

delicate olive
smoky salmon

Yeah

delicate olive
smoky salmon
#

Oh I’m sorry typo

#

I meant recorrect

delicate olive
#

So when that runs again in the update, the force you added is basically removed completely

#

And not taken into account

smoky salmon
#

Yes exactly

#

And I’m not really sure what to do then

delicate olive
#

If I were to use AddForces on a player controller, I would convert the entire movement logic to just be AddForce

#

That's the only solution I can think of

#

And then clamp the max velocity to whatever you want

smoky salmon
#

Hm okay

#

Sort of specific question

delicate olive
#

But then you'd somehow have to manage not clamping the high wall jump velocity you just added so Idk

smoky salmon
#

Yeah exactly

#

That was the question

#

Oh well I’ll try to find a way

#

Thanks for helping

delicate olive
#

Okay good luck mate

#

One more thing; you could also just disable the movement entirely for some duration after wall hopping for example, or you could have a seperate Vector3 that you add any extra velocities you want and use that in the movement calculations

#

The latter actually seems pretty reasonable to me

#

Then lerp it in Update towards 0 so it dissipates as time goes on

#

@smoky salmon

smoky salmon
#

Ooh I see

#

That’s actually not a bad idea

#

Thanks!

# junior salmon Is it possible to change the saturation of a volume in post processing in a scri...

The volume itself does not have "saturation", it has a "weight" you can adjust which lowers the visibility of all effects on it, but if you just want to modify a specific effect, you would have to get a reference to that effect, for example "Bloom", then you could modify the values of "Bloom" by script, or whichever effect(s) your trying to change, this link may help: https://forum.unity.com/threads/how-to-modify-post-processing-profiles-in-script.758375/#post-5622541

If you want it to use the value from when the method was called, cache it in a local variable and use that.

You probably divide by 0 somewhere or something.

fluid lily

"
In C#, comparing a floating-point value directly to float.NaN using the equality operator (==) will not work as expected. This is because NaN (Not a Number) is a special value, and comparing it directly with the equality operator is always false. This is due to the nature of floating-point arithmetic and the fact that NaN is not equal to any other value, including itself."

how can i make it so rigidbody2d.addforce acts like modifying the velocity, as in, there's no acceleration time or deacceleration time, the moment you press and let go of the arrow keys you reach max speed and slow down immediately

mainly trying to use addforce for movement instead of just modifying the velocity directly because later i want to add knockback with addforce

but if i modify the velocity directly its going to be a pain later

Probably a dumb question;

I want to make a game that's like a super simple top down 2D shooter (like Vampire Survivor but even simpler).

I want the enemy that kills you to activate certain events (like a cutscene)/be reported in the end (killed by X) and have the enemies have variety in whether they can shoot bullets/not, how fast they can move (or no movement which I assume would just be a variable = 0) and if they can be dodged through.

Would I use scriptable objects to make the various enemies here? I've honestly always had trouble figuring out what's the best way to handle different enemy types that share very similar codes/things.

Honestly even stuff like enemy spawn and accounting for each enemy with simple AI and health is kind of new for me. I'm coming back to unity after like 3~4 years and the last thing I worked on was 1 VS 1 lol.

Hi, i am kind of struggling with positioning my Gameobjects correctly, i am not sure why it will not respect the z position. i instantiate a car gameobject using this script.

public GameObject GetRandomCardFromCardSafe()
   {
       int randomIndex = UnityEngine.Random.Range(0, cardSafeCards.Count());
       // Return a random card from playerDeck
       GameObject randomCard = Instantiate(cardSafeCards[randomIndex], Vector3.zero, Quaternion.identity);
       Debug.Log("Random Card From Card Safe: "+ randomCard.name);
       return randomCard;

   }```
#

and i further modify them for this specific scene cs instantiatedCard = deck.GetRandomCardFromCardSafe(); Debug.Log(instantiatedCard.name); instantiatedCard.SetActive(true); instantiatedCard.transform.SetParent(transform); instantiatedCard.GetComponent<CardMovementHandler>().enabled = false; instantiatedCard.AddComponent<Drag>(); instantiatedCard.GetComponent<RectTransform>().position = new Vector3(0,0,0);
but every object i instantiate this way ends up with z -935.3074 while i would love it to be 0. i have tried everything i could think of and google thought of.

#

these are the components of each card gameobject if it is any help

My google results usually brought me to deprecated docs.
i simply set the parent of the object i am moving to the new sorting group.

#

anyone here have any idea about how to configure multiple display for UWP build

dusk haven
delicate olive
#

Are thos scroll rects? If they are I highly recommend you to add those to your layouts

#

Then when a card is changed/added/removed use the static LayoutRebuilder class that Unity provides

#

Use a method like MarkLayoutForRebuild() with the layout root's rect transform as the parameter

#

ForceLayoutRebuildImmediate() also works but it is more expensive so use it only when you have a lot of nested groups

dusk haven
#

normal recttransforms, we have sized the content to fit the cards

#

i though ForceLayoutRebuildImmediate() was not in the current unity version anymore? 🤔

delicate olive
#

From the video it seems it should scale dynamically

dusk haven
#

wait, the card object or the layout groups?

delicate olive
delicate olive
#

Or did you reply to the other question

dusk haven
delicate olive
#

No, the cards' sizes should stay constant, only the layout groups' "content" objects should be scaling

#

So if you want them to scale, add the contentsizefitter to the Contents and config the appropriate fields

dusk haven
#

the text should remain readable so i am planning on making the group scrollable

This would also be more appropriate discussion in #📲┃ui-ux than in here I believe, but whatever

#

What does Interpolate do ?

cosmic rain
#

Physics updates the position of your rb every fixed update, however the game is rendered in the regular update which can happen more often. That's why objects moved by physics look jittery - they're not moving continuously. Interpolation fills the gaps by moving the rb in between fixed updates as well(interpolates between the current fixed frame and next fixed frame position in the regular update).

For some reason my jump is not working, is there anything I need to add or remove? Just to let you know I also added the Rigidbody to the Rb

Is using a lot of properties good or bad habit?

# dusky pelican Yep, it's manager.

Not related to properties but what stands out to me are the factory machine part class names. I don't think it's common practice to use Prefix_ClassName, people often use namespaces to group classes instead

#

Like "namespace <game name>.Factories" at the top of the class

dusky pelican
#

You're right! I will make it like that. Thanks for advice. So there's nothing wrong about using that much properties right?

delicate olive
#

Is that for holding prefab instances for other scripts to instantiate?

delicate olive
dusky pelican
#

It's kinda like, i have machines in production setup. Each Production Setup contains five machine. So for creating multiple production setups, i use that way.

delicate olive
#

But that's like the only way in my case so

Hi, so I've got a mod for a unity game, and the error:

[Warning: Unity Log] The referenced script (UnityEngine.XR.Interaction.Toolkit.UI.TrackedDeviceGraphicRaycaster) on this Behaviour is missing!

occurs when trying to run the modded game, I don't get any errors building

UnityEngine.XR.Interaction.Toolkit is in the project references too, could I get some pointers in the right direction to look?

Because they group them to the production step, which is quite necessary

I'm having issues initializing a jagged array

knotty sun
primal wind
#

chunks is declared elsewere but i added it here to not confuse

Chunk[][][] chunks = new Chunk[RealmSizeInChunks][][];
Debug.Log(chunks.Length);
for(int i = 0; i < chunks.Length; i++)
{
    chunks[i] = new Chunk[RealmHeightInChunks][];
    for(int j = 0; j < chunks[i].Length; j++)
    {
        chunks[i][j] = new Chunk[RealmSizeInChunks];
    }
}

#

and Chunks is initialized?

#

cos that looks ok

primal wind
#

I mean, i did the same thing before i added a new array on top of it for 3D

#

And it worked

#

Maybe i broke something without noticing

knotty sun
#

what error are you getting?

primal wind
#

IndexOutOfRangeException anytime i try doing anything with it

knotty sun
#

is Chunk a class or a struct?

primal wind
#

it looks like that when i use a breakpoint

primal wind
#

Tried making it a struct but caused issues i didn't want to have yet

knotty sun
#

you are using both Height and Size, is this correct?

primal wind
#

yes

knotty sun
#

Debug both RealmHeightInChunks and RealmSizeInChunks

primal wind
#

Oh its 0 somehow

versed light
primal wind
#

I even set the values manually and it works

knotty sun
#

public variables?
