It should save the image to ImagePath in D disk

[rigid island]

that's not helpful. We understand that part

but do you see logs, etc.

be more specific and let's not play 20 questions here

[long totem]

there is no error in logs

[thin aurora]

Confirm it gets through the code.
Confirm m_strImagePath is a valid location.
Confirm pngBytes builds a proper image, or has any bytes at all.

[swift aspen]

Anyone got any ideas about this custom pass issue? HDRP chat is very slow 🙂 #archived-hdrp message

[fluid lily]

Okay question. Is there anyway to get a projected position for a PlayerCharacter? Like I could do the math, but I am hoping there might be something built in for physics. Like what the position will be in a fixedUpdate later then the current one?

I am wanting this so I can have the camera/character graphics still be moving every frame, while the physics collider is between calls.

As the graphics/the camera renders at 120fps currently.

and physics is 40

Or possibly have physics update at 120fps for only the player character object?

[main shuttle]

Kind of depends on your PlayerCharacter.

Extrapolation will predict the position of the rigidbody based on the current velocity.
https://docs.unity3d.com/ScriptReference/RigidbodyInterpolation.Extrapolate.html
There are a whole bunch of extrapolate or interpolate functions, you could study those if they fix your issue.
But afaik the basic extrapolate can't predict far into the future, but its probably a good starting point.

[fluid lily]

Ah nice. Yeah I don't need more than an an update or two, so that might do the trick

[steep prism]

I'm trying to use the GL system to draw lines but can't seem to get GL.Multmatrix method to work. The lines won't leave the default world rotation/position.

Right now my code is as follows: (abreviated)

//class GLLines
void drawLine(Color color, Matrix4x4 matrix,Vector3 Start, Vector3 End)
{
GL.PushMatrix();
//GL.LoadIdentity(); //tried both with and without
GL.MultMatrix(matrix);
GL.Begin(GL.LINES);

GL.Color(color);
GL.Vertex(Start);
GL.Vertex(End);

GL.End();
GL.PopMatrix();
}

void Update()
{
  GLLines.drawLine(Color.red, transform.localToWorldMatrix,Vector3.zero, new Vector3(512,256,0));
}

what am I doing wrong here?

[long totem]

So I try that on another computer and it shows this

Does that mean there is something wrong with my codes or VS?

[crude mortar]

you have to also multiply your matrix by the camera worldToCameraMatrix

you can use Camera.current if you want it to also work in the scene view

but you will want to call the method in OnDrawGizmos also

you are recreating the behaviour of Gizmos.DrawLine though, just so you know

[thin aurora]

It refers to AssemblyInfo.cs which is not that file

Which is weird

[steep prism]

Interesting to know, but I want to use this code in a build so gizmos wouldn't be usable.
Sadly enough, it doesn't seem to change the result

[crude mortar]

what is your new code?

[steep prism]

void Update()
{
  GLLines.drawLine(Color.red, transform.localToWorldMatrix * Camera.current.worldToCameraMatrix,Vector3.zero, new Vector3(512,256,0));
}

The other code has not changed

[crude mortar]

uncomment the load identity line in the drawline method

and I think you can use OnPostRender() if your script is attached to a camera

[steep prism]

Uncommenting load identity doesn't change the result :(

[steep prism]

I thought that OnPostRender didn't work in URP?

[crude mortar]

you never said you were on URP, but regardless I have no idea

        [UsedImplicitly]
        private void OnPostRender()
        {
            var matrix = m_lineParent.localToWorldMatrix * m_camera.worldToCameraMatrix;
            DrawLine(Color.red, matrix, Vector3.zero, Vector3.up, m_material);
        }
        
        private static void DrawLine(in Color color, in Matrix4x4 matrix, in Vector3 start, in Vector3 end, Material material)
        {
            material.SetPass(0);
            GL.PushMatrix();
            GL.LoadIdentity();
            GL.MultMatrix(matrix);
            GL.Begin(GL.LINES);

            GL.Color(color);
            GL.Vertex(start);
            GL.Vertex(end);

            GL.End();
            GL.PopMatrix();
        }

this works fine for me though (I am on standard pipeline)

https://forum.unity.com/threads/onprerender-onpostrender-counterpart-in-srp.535875/

the math should at least work in OnDrawGizmos though

then you could figure out how to make it work in the build

[steep prism]

that doesn't work on my end, at this point I'm stumped as to what it could be that causes it to not work. Thanks for help though, really appreciate it

[crude mortar]

weird, I blame some URP magic, not sure

unfortunately don't have a URP project for testing

https://forum.unity.com/threads/gl-lines-and-gl-functionality-with-lwrp.618985/

yeah, seems like there is URP weirdness interfering, you might have to experiment a bit

the math is fine though, it's just a matter of where the code gets ran

[steep prism]

damn, alright. I'll try some things out and see if I can get it to work.

thanks!

[golden vessel]

Hey, I'm trying to stop a coroutine before starting again, but somehow the coroutine I stopped still runs, and interferes with the next one.

          combatEffect.currentBubbleCoroutine = StartCoroutine(combatEffect.CombatDialogue(buckAI.dialogueBuck[5]));```
Any idea what could be the problem pls?

[plucky inlet]

Is your coroutine maybe starting another one inside?

[golden vessel]

Oh...

[golden vessel]

Yeah I didn't think about that, I need to stop both then

[plucky inlet]

How do you call the other one?

[golden vessel]

    {
        List<(int, bool)> sentenceCut = CutSentence(text);
        bool ponctuation = false;
        bubbleObject.SetActive(true);
        bubbleText.text = text;
        bubbleText.color = new Color(0, 0, 0, 1);
        bubbleRend.color = new Color(1, 1, 1, 1);
        SetVoices(sentenceCut);

        int letterCountToNextSound = 0;
        bubbleText.text = "";
        foreach (char letter in text)
        {
            if (letter == ' ')
            {
                bubbleText.text += letter;
                yield return new WaitForSeconds(0.025f);
                continue;
            }

            if (letter == ',' || letter == '.' || letter == '?' || letter == '!')
            {
                ponctuation = true;
                bubbleText.text += letter;
                yield return new WaitForSeconds(0.025f);
                continue;
            }
            else if (ponctuation)
            {
                yield return new WaitForSeconds(0.25f);
                letterCountToNextSound = 0;
                ponctuation = false;
            }

            if (letterCountToNextSound == 0)
            {
                PlayNextSound();
                letterCountToNextSound = 4;
            }

            letterCountToNextSound -= 1;
            bubbleText.text += letter;
            yield return new WaitForSeconds(0.025f);
        }
        yield return new WaitForSeconds(3f);
        StartCoroutine(FadeBubble());
    }```

[plucky inlet]

!cs

[tawny elk]

You can format your multiline code block with C# highlighting! Just add cs to the start of it. Highlighting example below!

class Fluffs : FluffyCat
{
    public void PetCat ()
    {
        Debug.Log ("Petting Cat.")
    }
}

[plucky inlet]

ah so your fadebubble is the one that is still running, right?

[golden vessel]

Basically it makes a bubble pop and fill it with text, than it makes it fade. But I guess there's a timing where the FadeBubble is running while the other one has stopped

Makes a lot of sense, I didn't think about that thanks a lot

[plucky inlet]

you are welcome 🙂

[worldly zealot]

I'm trying to set the simulation time for HDRP Water Surface so I can sync it in multiplayer but I don't see anything for that...

[golden vessel]

What's the point of making a material synced in multi? I thought that was a client side thing

[plucky inlet]

Maybe for something like Sea of thieves to have the same waves going on

[worldly zealot]

exactly

if not synced, one might see a big wave but host sees nothing and it gets weird

[plucky inlet]

Did you check the shader and its values? Like the code version of the shader to see what modified it actually makes available?

[worldly zealot]

where is the shader?

[plucky inlet]

right click you rmaterial of your water and edit shader or script or something should appear

Let me check

[golden vessel]

Well, for a case like this I thought you'd base the shader on the physics

[golden vessel]

But yeah I'm not knowledgeable about multiplayer to say I'm confident about it

[plucky inlet]

You rather set the values for all palyers and the client will react physically.

[worldly zealot]

it doesn't have a material i can assign a custom one

[plucky inlet]

Oh okay, let me check, never used the hdrp water itself. Can you link it real quick?

[worldly zealot]

no documentations on Water Surface component either

seems like a new thing

[plucky inlet]

Ohhh, its a totally unique component. welp, can you right click edit script?

[worldly zealot]

yes i did check the script
there seems to be a section for simulation time which is private...

[plucky inlet]

But maybe you can overwrite the full renderingparameters?

Like you have to do with particlesystem emission modules, maybe this is also some kind of module

[worldly zealot]

there is nothing for that

[plucky inlet]

Well it is quite new, gonna look at that myself in the next days. I would just tinker and test around with the scripts and see if I can overwrite anything or create from scratch in a script

[edgy sage]

Do you think there's something wrong with this code?

var go = new GameObject("_Guardian")
{
    transform =
    {
        position = transform.position
    }
};

var constraint = go.AddComponent(typeof(PositionConstraint)) as PositionConstraint;
if (constraint != null)
{
    var source = new ConstraintSource
    {
        sourceTransform = transform
    };
    constraint.AddSource(source);
    constraint.constraintActive = true;
}

It creates a GameObject called "_Guardian" and adds PositionConstraint component to it which has another gameobject (transform) as source transform. For some reason this _Guardian gameobject does not follow sourceTransform even though when I do exactly the same setup in the Unity editor it works.

[leaden ice]

You can't assign the Transform of a GameObject.

You should just use the generic form of AddComponent

Did you mean to make the object the script is attached to be the constraint target?

[crude mortar]

also not sure why you are checking for a null constraint when you just created it

[leaden ice]

Probably because of the as cast

Which is a side effect of the whole not using the generic form of AddComponent thing

[edgy sage]

Generic form?

[crude mortar]

go.AddComponent<PositionConstraint>();

[leaden ice]

You should probably set the weight of the constraint source too?

[edgy sage]

It is 1 by default and in the inspector everything looks like when done manually

I will try with generic approach if that makes a difference

[leaden ice]

There's other fields too like https://docs.unity3d.com/ScriptReference/Animations.PositionConstraint-translationAxis.html

[edgy sage]

Maybe this constraint is somehow broken in Unity 2022.2.x which I'm using... no luck

[leaden ice]

Show the inspector of your object

After creation

I really think your field initializer for the Transform is fucked though

[edgy sage]

Transform is the yellow highlighted one

[leaden ice]

All position axes are frozen

Isn't that wrong?

Also the source weight is 0

That's also wrong

[edgy sage]

Actually that might be the reason, source weight.. I thought it was source index

But axis is set like that also when it's working when done manually

Yep, working now that I set source weight

Thank you, I missed that one when trying to figure out what is the difference between manual setup and scripted 🙂

Following the player nicely now.

[proven path]

What would happen if I try to deserialize a json file, containing a deriving class as their base class. Can I cast it into the deriving class afterwards, or will it just throw an error?

[leaden ice]

Depends on which serialization framework you use

In general you would need to store type information with the data

Newtonsoft JSON has support for this

[proven path]

Okay thanks! But I am using JSONUtility so I guess will have to find some sort of workaround then.

[somber nacelle]

jsonutility is pretty barebones tbh. i'm not even certain it supports polymorphic deserialization. you'd probably have a better time switching to newtonsoft

[plucky inlet]

Unity now holds newton as a package itself, you can just use it instead of JSONUtilitiy

[thin aurora]

Forgetting JSONUtility has ever existed is the best thing you could ever do

Unity has a Newtonsoft package which is a million times better

The limitations of JSONUtility is so laughably bad that I am surprised Unity even still has it available as an actual feature

[proven path]

I will give Newtonsoft a try then; thanks guys!

[unreal temple]

How can I serialize an SO into the UserSettings/ folder?

[unreal temple]

I still rock it

[leaden ice]

The novelty of JSONUtility is that it uses Unity's standard serialization mechanism. It's also faster than Newtonsoft

[stiff tide]

I have a frustrating bug that googling doesn't seem to find anything.

I'm loading images (sprites) from a 'Resources' folder using, 'Resources.Load<Sprite>'
This function/method is called once, when the card is created. It sets the image, and all is good. At a later time, it's called once, setting the image/sprite of another object. Which works. It finds it's own image, and it finds the other object's image. But... it then changes what it's own image is. It never actually does it, it only runs this search again. Which gets applied to both objects for whatever reason. It's retroactively changing the variable of the first one.

In short,
Image1 = Image1.png
Image2 = Image2.png
Now Image1 and 2 both equal 2.

public Sprite SearchDownloadCardImage(string cardName)
    {
        // In the future, this will actually search for and download images. Right now it can only pull files that are already downloaded.
        try
        {
            Sprite result = Resources.Load<Sprite>("Card Images/" + cardName);
            if (result != null) return result;
        }
        catch
        {
            Debug.Log("Failed to find '" + cardName + "' in the Resources file.");
        }
        return DefaultImage;
    }```
With a bunch of debugging, I'm 99% sure it's only this line of code breaking things.

[orchid bane]

Anyone knows where to find navigation algorithms for such a node map?

[stiff tide]

A visual of what happens btw. The large image on the side should be a zoomed in picture. Finding that picture (when no sprite of it exists), requires I search the files again. Which changes the original.
https://gyazo.com/2d2db811d80a6554b8b8d82f38285fb0

[thin aurora]

Poor guy

[thin aurora]

Yeah my game is also 100 times faster than the next triple A game but it's not gonna beat that game any time soon when it comes to actual features and such

Because as soon as my shit game is actually going to function like it's supposed to it will encounter a lot of features that will chew on that performance

Now take a guess how JSONUtility relates to this

[twin stag]

Unity is throwing an error up in a class I made when I try to make a public image variable saying "the type or namespace 'image' can't be found" but I have got using UnityEngine.UI; at the top. It's a 2nd class inside the same file as another class. A tutorial done in 2020 Unity shows this working but it's not in 20201 LTS Unity.

[somber nacelle]

make sure you're spelling it correctly

[twin stag]

It's a PlayerNeeds class file with a 2nd class of "public class Need"

public image uiBar;

[proven path]

Make sure that image is uppercase.

[somber nacelle]

make sure that your !IDE is configured so you don't make spelling mistakes like that

[twin stag]

using UnityEngine.UI; is at the top of the file

[tawny elk]

[tepid river]

the loading part itself should create 2 distince sprites that dont share anything, i assume even if you load the same sprite twice

[twin stag]

oh yeah umm I changed the editor in unity preferences before to visual studio community but the change didn't stick 😦 no idea why not

[tepid river]

so thats not the cause. the DefaultImage could become a shared object
all in all, i smell that this method is probably not the cause

[somber nacelle]

you may need to launch unity as admin if the setting didn't stay after restarting. you can do so by completely closing unity and the hub then launching the hub as admin

[twin stag]

ahh ok cool ty 🙂

[stiff tide]

Default image is never used. This method is the only thing that sets the card's image, and sets the zoomed in one, when it's alone (in play). When the one line that calls this method is commented out, everything is fine. (It just doesn't display anything when the card is in play. If I were to skip calling this method during the in play exception, and skipped right to giving it the Default image, everything is good.

This method is retroactively changing what it found the first time.

[tepid river]

sprite and cardname are local to the methods scope. it cant change them that way. can you show the surrounding code?

[stiff tide]

It should make two distinct spite variables, but that's not what happens for some reason

I can... but I just left for work. So I can't do it for a few hours sadly. Ttyl

[high violet]

any idea to implement AI that you pointed
I have done the previous steps just creating the AI is left which seems to be important 😅

[orchid bane]

How do I give such red and green outlines dynamically?

[leaden ice]

This is a standard graph and will work with standard graph algorithms like Dijkstra's, A*, DFS, BFS etc

[thick socket]

can't even serialize dictionaries smh

[thin aurora]

Can't even serialize arrays without wrapping it in an object first

[somber nacelle]

it can just not as the root object

[thin aurora]

Yes that's what I mean

[lost wave]

when the game moves from lvl 2 to 3, the transition animator controller gets removed from the inspector. It works fine from lvl 1 to lvl 2.

[thick socket]

I dont think the issue is on that code

[lost wave]

all the errors that are thrown, reference it. I'm certainly not saying your wrong, but I am def stumped.

[thick socket]

tbf

you didn't share the errors

[lost wave]

MissingReferenceException: The variable transition of LevelLoader doesn't exist anymore.
You probably need to reassign the transition variable of the 'LevelLoader' script in the inspector.

[maiden breach]

Where are you setting that transition variable?

Find All References

look for ones that write

[orchid bane]

How do I get the prefab of a prefab instance?

[maiden breach]

click the select button in the inspector

[lost wave]

at the top, Animator transition.

[orchid bane]

I mean with code

[thin aurora]

If you instantiate an instance of the prefab you must have a reference to it somewhere

[plucky inlet]

What exactly do you want to do?

[plucky inlet]

It tells you what to do, doesnt it?

[maiden breach]

You're not referencing it anywhere else in code? make it [SerializeField] private instead of public and see what happens

[orchid bane]

I have a serialized list of references to prefabs and I need to get index of my GameObject's prefab (original) from this list

[lost wave]

is is assigned and when the lvl changes, it gets unassigned.

[plucky inlet]

the list of referenced prefabs is runtime prefabs or drag dropped from the project view?

[orchid bane]

drag n drop

[plucky inlet]

then you can just pass in the indexOf your prefab to your runtime reference

[plucky inlet]

Does your new level also have the thing assigned correctly?

[orchid bane]

Can you rephrase?

[plucky inlet]

If you have a list, you can use IndexOf(yourPrefabSource) to pass in a value to your prefabInstance. So you set it when instantiating.

[orchid bane]

I don't understand what "to pass in a value to your prefabInstance" means.
As I see it, I need first to get the prefab of my prefab instance

[plucky inlet]

you might wanna reprhase your question. Why do you need the index of the source?

[lost wave]

yes, all scenes it is assigned.

[maiden breach]

did you change from public like I said?

[plucky inlet]

How did you assign it? Do you open multiple scenes in edit mode and assign frmo scene A to scene B? So crossscene references?

[orchid bane]

Because Popup from UI requires working with ints so I need to pass there an int, the index in my case

[plucky inlet]

do you have some code to look at? where you instantiate and where you need the index?

[orchid bane]

Something like this for the moment

int currentIndex = Array.IndexOf(agent.nodeMap.nodeData.agentPrefabs, agent.agentPrefab);
_agentTypeIndex = EditorGUILayout.Popup(currentIndex, agent.nodeMap.nodeData.agentPrefabs.Select(x => x.name).ToArray());
agent.agentPrefab = agent.nodeMap.nodeData.agentPrefabs[_agentTypeIndex];```

[plucky inlet]

Let me lookup the popup function, never used it. Should have told you are working in editor scripts 😉

[orchid bane]

Sorry

[lost wave]

yes, I got the same errors, Im trying to find other refs, but I had some other stuff come up.

[plucky inlet]

So what part of the code is your issue now? The currentIndex value? Is it wrong, do you get any error?

[lost wave]

its a game that is built one island. each scene/lvl is a duplicate of the first and then objects are moved around to create new tracks to drive on. I have opened each scene to make sure it is there before testing.

[orchid bane]

Want to simplify the insides of Agent. It now has reference to the created GameObject so I was thinking of calculating the index using it instead of keeping reference to the prefab in Agent

[plucky inlet]

Your problem might be, that you close one level and then it loses the reference. when you click on Scene B on the reference that gets missing in playmode, does it direct to scene B or another one?

[vestal geode]

Are switch expressions just lambda expressions for a switch statement, or something more?

[plucky inlet]

Oh well, looking at the microsoft docs, they might be a little different as you can convert values to a desired target value on different types

[plucky inlet]

public static Orientation ToOrientation(Direction direction) => direction switch
    {
        Direction.Up    => Orientation.North,
        Direction.Right => Orientation.East,
        Direction.Down  => Orientation.South,
        Direction.Left  => Orientation.West,
        _ => throw new ArgumentOutOfRangeException(nameof(direction), $"Not expected direction value: {direction}"),
    };

Hence this example here

[lost wave]

Im sorry, im not following you.

[plucky inlet]

Just answer the last question 🙂 You set the references in the inspector. What is reference from Scene B pointing at? At an object on scene B or another scene?

[unreal temple]

Is it possible to modify/preview a material property block in the editor?

[quaint rock]

if you can invoke the code for it while in editor mode sure

[unreal temple]

I want the optimisation without losing the nice material editor.

[unreal temple]

That's what I thought.

Yeah, I can do that haha, going to be annoying in prefabs though.

[quaint rock]

though generally its not used for static stuff

but per instance changes

[unreal temple]

Well yeah.

But that doesn't mean you don't want an artist to pick the colors and preview them

Or is there no difference between property blocks and authored materials for performance?

[quaint rock]

but yeah you could easily hook it up in OnValidate or something

so it changes during edit time

[unreal temple]

Yep, it's easy enough to do for sure.

[late lion]

Depends if you're using SRP Batcher or not

SRP Batcher prefers material instances

[unreal temple]

Is that something that's on by default in URP?

[late lion]

I imagine so. I think it's a hidden setting.

[unreal temple]

Okay, so we're probably using it. In that case it will be easier to just create materials.

Seems I have wasted some time here.

[late lion]

Yeah, I said "prefers", but MPB actually breaks batching when using SRP Batcher. It just doesn't know what to do with it so it doesn't combine it with anything.

[unreal temple]

That's good lol

Certainly good to know, thanks

[late lion]

It can still fallback on GPU instancing if the material supports it.

[unreal temple]

I'm not even concerned about performance, I'm just mildly worried about artists authoring a whoel bunch of the wrong kind of asset.

[late lion]

Material variants in 2022 will help with this.

[unreal temple]

Oh, we're about to upgrade to 2022

Ah, just like a prefab variant

Nice.

[late lion]

Prefab Variants and Material Variants have much the same functionality, ... There are two key differences between them:

You can reparent a Material Variant.
You can lock Material Variant Properties.

[unreal temple]

Beautiful

[plucky inlet]

Uhh the second one is nice

[golden vessel]

Hey, is the Time.time accurate for audio? I'm pretty sure music still runs in most game when having a freeze, so I suppose it's not.
I'm trying to count the time so that I can switch music on a beat

[lost wave]

Just answer the last question 🙂 You set

[hard sparrow]

I've got text with a content size fitter inside a layout group (so the textbox resizes automatically). But it doesn't correctly update the first time text is posted. I'm even doing THIS

[late lion]

There's AudioSettings.dspTime

[golden vessel]

Yeah I just noticed it in the example for AudioSource.PlayScheduled

[deep fable]

Any idea on how I could procedurally generate a desert? (like the one in the photo, source: https://blenderartists.org/t/procedural-desert/1321823)

I was thinking about using cellular noise to generate the dunes, and then use a "zoomed out" perlin noise to offset the dune height (and avoid that every dune has the same height), but dunes don't seem to have straight edges like cellular noise does

[hard sparrow]

This is (I thought) forcing the text to update and the layout group to update... but it still doesn't do anything initially

[plucky inlet]

you could offset the x z values depending on the y value in a "wind direction"

[golden vessel]

How many of these timelines are they btw? Cos I can count at least the usual one, the physics one, and the audio one

[deep fable]

and make the wind like a bit of a randomized sine function.. it seems like it could work!

Maybe I could something like a 1d perlin noise to offset the dune

Thanks!

[hard sparrow]

dunes often do have sharp edges though

[deep fable]

But that's a feature that also cellular noise has (don't mind the 3d sphere)

Maybe it's not that good the cellular noise.. I'll see

[plucky inlet]

you could just have a range decreasing for the x values too while that range gets offset depending on the y value

[late lion]

Physics tries to keep up with Time.time, in fixed steps.

[plucky inlet]

like decrease the range to get sharper edges AND shift that range to get those steep cliffs

[late lion]

I think Audio is the only one that's completely separate.

[hard sparrow]

So should this be having the effect I want it to have? actionDescription being the text itself and actionAttributeLayoutGroup being the vertical layout group of the parent object which the text is childed too.

[golden vessel]

Makes sense, freezes would be horrible in gameplay

Thanks, I'm pretty sure I'll just adapt the example of PlayScheduled on the unity docs, but I wanted to understand it beforehand

[hard sparrow]

First time this menu is brought up (first time text is populated)

Second time. (This is correct)

Is this a normal issue or

[golden vessel]

That's what happens when you don't do ForceRebuildLayout

[hard sparrow]

!!!

[plucky inlet]

You might not rebuilding the correct parent

[golden vessel]

Maybe you change stuff before the rebuild? Idk I've had trouble with that as well and ended up doing it in editor rather than code

[hard sparrow]

Hm? Don't you want to do the rebuild as the last thing?

[golden vessel]

Yeah that's what I meant

[plucky inlet]

Maybe show your full code

[hard sparrow]

Does ForceMeshUpdate on the text do anything relevant?

[plucky inlet]

It updates the TMPro but not really playing into the UI recalculation at first I think

[hard sparrow]

It's basically just inserting a bunch of text from places and then doing the layout rebuild

I'll play around with it some more

[golden vessel]

I'll just put that link there, I followed the tutorial and it saved me a lot of troubles

[plucky inlet]

Do you reubild after the bunch or after every text?

[golden vessel]

Actually I didn't at first and ended up spending hours for it not to work aha

Still having an issue with being able to set the "plant" GameObject to be 10 below the current y value of a TunnelArray object, it moves to the spot, just not 10 below.

[hard sparrow]

Lol, yes, it appears I was overcomplicating it. Had an unnecessary content size fitter which apparently was messing things up

[golden vessel]

What do you mean by "not 10"? I think the problem is between local and non local scale

[pearl swallow]

Like it should be subtracted by 10.

[golden vessel]

If the object is not root of the hierarchy, and one of its parents scale is not 1, the position will get affected by the scale

[pearl swallow]

Like say if it was put at 0,10,0, the code should just have it be 0,0,0.

I'm not sure I follow.

[golden vessel]

Say you have 2 objects, one parent and one child

If the parent scale is (1,1,1), and you code child.transform -= new Vector3(0,10,0), the transform will be the same, -10 on the y axis

If the parent scale is (2,2,2), the child transform will be the same, -20 on the y axis

If you want the child to be the same -10 on the y axis, you need to use transform.localPosition

Rather than transform.position

[pearl swallow]

I'll try that, thank you.

[blissful flower]

So I have a line like this

where Unit is a general Unit script. Recently I refactored some stuff so that now different units have their own unit classes that just inherit the general Unit

(so UnitMage : Unit, UnitWarrior : Unit, UnitGoblin : Unit)

[leaden ice]

I think that's a bad practice in Unity in general to use polymorphism that way 🤢

[blissful flower]

how do I get that component without knowing the actual name of the class?

[leaden ice]

GetComponent<Unit> will still work

They are all still Unit

[blissful flower]

Yep it does but when I try to get unit.skillArts[0] for example, I don't think that works anymore?

[leaden ice]

Why not?

is skillArts part of Unit?

Then it will work

[blissful flower]

yeah, so it should work? hmm

[leaden ice]

Better practice btw would be for those GameObjects to just have multiple components:
Unit AND Goblin
Unit AND Warrior

composition > inheritance for Unity

[blissful flower]

🤔

So hold on... could Goblin or Warrior in that case still inherit Unit or not?

[leaden ice]

It should not

that's the point I'm making

don't use inheritance like that

What happens if you want a GoblinWarrior

or a Goblin with a shield

Do you make GoblinWarriorWithShield: GoblinWithShield : Goblin : Unit ???

It's not a good model

the better model is you have a GameObject named GoblinWarriorWithShield that has multiple components attached:

• Unit
• GoblinAI
• Shield

[blissful flower]

But in my case I have like 50 heroes/units that all share the basic rules for everything, like default movement, taking damage, having two skill buttons (one of which can be disabled) etc.

[leaden ice]

right

that's what the shared components like Unit are for

[pearl swallow]

Still does not appear to be working, but I'm wondering now...

Would the Start method override anything?

[blissful flower]

So what if I want to override something in Unit? Let's say that Warrior doesn't use default movement but a slower movement instead

and it has the Unit and Warrior components

what does the Warrior component do if it can't inherit the default movement even (to be overridden)?

[leaden ice]

Make movement a separate component entirely

or movement is handled in Warrior / Goblin, not in Unit

And can't "slow" just be handled by a public float speed; variable on one of the scripts?

You don't need inheritance to have a different speed value

[blissful flower]

No because the movements are tile-based and might be in different shapes, not a value

[leaden ice]

So you have:
TilebasedMovement
LMovement
etc. components

these should not be part of Unit

[pearl swallow]

    //The "Tunnelling" section for the Plant. Plant burrows down, selects spot before coming up in later section.
    public void PlantTunnel()
    {
        plantIndex = Random.Range(0, 3);
        plantStatus = 1;

        transform.localPosition = tunnelArray[plantIndex].localPosition + new Vector3(0, -10, 0);

    }

    public void PlantUntunnel()
    {
        transform.localPosition = tunnelArray[plantIndex].transform.localPosition;
        plantStatus = 2;
    }

Was this what you meant when using transform.localPosition?

[leaden ice]

or maybe Unit just has a MovementStrategy enum field

etc..

I'm throwing things out there because I don't know how your game really works but, reaching for inheritance to solve every problem is a bad instinct in Unity.

[blissful flower]

Well the core issue is... my Unit script is like 3000+ lines long, and it's structured so that each different hero or unit has a "UnitID" which is just an integer.
Then we come to the "CheckMovement()" function for example that checks which tiles the hero is allowed to move to based on their movement rules, and inside it there is a massive if else chain (not even switch for christ's sake) that checks if unitID = 30, check these tiles: if unitId = 35, check these tiles:
etc.

[pearl swallow]

Post it in Pastebin

[blissful flower]

doesn't that sound horrifying? And that goes for everything

and I figured I'd make a base Unit class that has the defaults for everything, and then each unit has an inherited UnitWarrior for example that might override the default CheckMovement() in some unique way

[leaden ice]

right so - this does sound horrifying. That's why all of the different units should be in separate scripts.

What I disagree with is that those separate scripts should inherit from Unit

movement rules in particular can be one script or a separate script hierarchy (BaseMovement, GridMovement, whatever)

[pearl swallow]

I figured it out

[leaden ice]

things dealing with basic health/unit targetting can be another script (the Unit script)

[pearl swallow]

if(plantStatus==1 && plantStatus < 5)
        {
            transform.position = tunnelArray[plantIndex].position + new Vector3(0, -10, 0);
        }

My solution.

So, it didn't update it... but did?

I put this in the update method just in case and it fixed it.

Welp, I'm happy now.

Also… 3000+ lines…

Why

That… I get maybe having 100+ if it’s like a really heavy script and it needs to be all in one.

But 3000+?

[blissful flower]

Okay this makes sense but it circles back to my original problem.

Let's say I have a function that should check movement of ALL units currently on the field

it would need to call the CheckMovement() (or similar) of each different Movement component

How do I do that?

Or actually... should Unit have a reference to it's correct movement checking script

[leaden ice]

foreach (Movement movement in allMovementComponents) {
  movement.CheckMovement();
}```

[leaden ice]

Unit can have a reference to the Movement script if they are separate, yes

[blissful flower]

That would actually make a lot of sense I think. So for each different hero I will go and have Unit component which has a Movement script reference, and for units that don't use the DefaultMovement script (for example) I just set WarriorMovement there. Would this make sense? So then I could make all units check their movement and they will do it using the attached movement script

Is this a sensible solution or am I still gonna do something horrifying

[leaden ice]

yes something like that sounds sensible

I think for Movement in particular inheritance might make sense within that area

it would then be super easy for you to mix and match things

like a Goblin with a TileMovement and another Goblin that has JumpMovement (just making things up)

[blissful flower]

Thank you so much for the help. Actually awesome explanations and I feel I learned something from this

I'm in for some insane labor though because movement is only one of the many things Units have. So gonna have to split the current gigantic Unit script to tens of other scripts but oh well this is a hole I've dug myself into

[sinful ginkgo]

how can i use .FirstOrDefault() on a NetworkList or at least convert the NetworkList into a standart list?

[haughty cairn]

hello, i am struggling to wrap my head around this problem, I want this cleaver to slice the fish in half, but the user will have control over where to slice. How could I dynamically slice the mesh? I was thinking of duplicating the object and hiding part of it, but cant find a way to do that. Would really appreciate advice (or point me to the right channel)

[golden vessel]

Was afk, not really sure since idk what tunnelArray is. If that's something you define in editor, like storing the value that you see of the object at its right place, yes.

[night bloom]

Is there a way to have 1 particle follow a path or game object. Example if i spawn a glowing knife that is supposed to chase a unit. Does that knife need to be a game object or can i do it with particles? the unit can run anywhere i just need the knife to chase it

[swift falcon]

why would you want it to be a particle instead of a game object?

[night bloom]

I have no preference. I just downloaded some cool effects and wanted to use them. they are all particle systems so i was wondering if that would work

[swift falcon]

just make a gameobject with the same texture and material and all that

and then look up on youtube how to make it follow another gameobject depending on if you want it to just go in a straight path or act like a missile or whatever

[eager yacht]

could try using something like this https://github.com/DavidArayan/ezy-slice (I've never used it personally but it's an option)

[haughty cairn]

oh! awesome! thanks! I also ended up finding this : https://www.youtube.com/watch?v=InpKZloVk0w which ill put in case anyone else has the same issue

[swift falcon]

does anyone know how i'd go about combining multiple images into one procedurally in script, but not just overlayed on top of each other or anything, but where each image takes up a portion of the image?
so if it's 3 images combined into one, each one takes up a third of the image

[maiden breach]

there are several paths of varying difficulty you could take. For what reason are you trying to do this?

for example, if you simply must have them combined into one image, it's certainly possible. But if you're just trying to show multiple images in the ui as one image, you could use Masks and it would be a lot easier and flexible

[swift falcon]

oh i think having them be multiple images but show as one would work just fine
how would i do that using masks?

[maiden breach]

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/script-Mask.html

Set them up in whatever arrangment you want and each mask gets a child with the image you want to show in their section

[pearl swallow]

I figured it out, update wouldn’t run the stuff well enough.

It triggered it, but didn’t update fully

Idk

[swift falcon]

i don't want to have them in sections like that though, i want all of them to be in the same spot but different parts of each be visible, if that makes sense

imagine a pie chart kinda deal

[maiden breach]

you can do that

[swift falcon]

oh i see what you're saying

i'm not sure how to get them in the arrangement that i want though

splitting it up like that i mean

[maiden breach]

I believe unity provides a circle sprite that you can radially fill

[swift falcon]

bet i'll check that out ty

[maiden breach]

@swift falcon no code necessary

doing it procedurally based on a variable number of images would be a different story

[swift falcon]

i would want to do it procedurally but i don't think it'd be too hard

[icy sundial]

is it possible for something to have a SortingOrder only within its context?

Does anyone know any good Unity beginner guides for people who already know how to code?

I'm looking for something like a series of tutorials on creating an example project that doesn't also teach you basic coding..

There's a lot to unity that isn't just API stuff

[maiden breach]

Not a dumb question. Unity development is conceptually different than traditional application development. Case in point - frames.

That said, Unity Learn is a good place to start @quasi stirrup

where did he say he doesn't know c#?

[quasi stirrup]

I know C#..

[crude mortar]

and since when is C# somehow unique from all other languages

[quasi stirrup]

and even if I didn't Java is extremely similar

[crude mortar]

most of them are quite similar

thats why they are asking for beginner guides

to Unity

[quasi stirrup]

I'm trying to find something for unity that doesn't try to teach me what a variable is for the 50th time, not exactly groundbreaking

[crude mortar]

imagine this scenario: you are an experienced 3D modeler, but you switch from Blender to Maya... You don't need to relearn basic topology rules and general good practices, you just need to learn the new tool

so naturally you would ask for beginner maya tutorials that already assume you know things about modeling

instead of starting from complete scratch

Hi, I'm trying to make an object swing like on a rope

        Transform attachedRigidBodyTransform = _attachedRigidBody.transform;
        Vector3 offsetToAttachedRigidbody = attachedRigidBodyTransform.position - transform.position;
        Vector3 directionToAttachedRigidbody = offsetToAttachedRigidbody.normalized;
        // Set the distance to the rope length.
        if (offsetToAttachedRigidbody.magnitude > _ropeLength)
        {
            Vector3 newPosition = transform.position + directionToAttachedRigidbody * _ropeLength;
            _attachedRigidBody.transform.position = newPosition;
        }
        // allow swinging of the object, 
        // by adding a force in the opposite direction of the offset.
        float forceMultiplier = Vector3.Dot(Physics.gravity.normalized, directionToAttachedRigidbody);
        _attachedRigidBody.AddForce(-directionToAttachedRigidbody * Physics.gravity.magnitude * forceMultiplier, ForceMode.Acceleration);

this is my rope code, the rope object is located at the anchor
the attached object swings, but it stops at the midpoint instead of swinging the other way
the rigidbody has no non-angular drag on it, and there is no other things affecting the swinging object
Why doesn't it swing properly?

[wintry crescent]

code is run in fixedUpdate obv

[quasi stirrup]

I'm not asking to skip learning API I'm looking for a tutorial that doesn't make me re-learn C#

hi ,
I wanna run function on a button is Pushdown/pressed even not on click
basically, I want to manually activate some animation/sound on press

you may say I want to create a custom PressedColor effect for the button

[leaden ice]

Add an EventTrigger component

and add a PointerDown event

(you can even delete the Button component if you don't care about normal button stuff)

[solemn raven]

Thanks ❤️

[wintry crescent]

can someone help me with this please?

I'm not sure where to even begin looking for the bug

[leaden ice]

what's the point of the force you are adding?

[wintry crescent]

to make it swing instead of fall, to simulate the pull of the rope on the object

[leaden ice]

Are you not using a joint?

[wintry crescent]

nope, just 2 objects with a script
that said, I could look up joints, didn't have a chance to use them before

[leaden ice]

typically ropes are made with HingeJoints

[wintry crescent]

I do not need to visualise the rope itself, I just need the object to float as if it was swinging, while still colliding with other objects

[leaden ice]

I didn't say anything about visualizations

[wintry crescent]

I mean - many hinge joints would require me to make a string of objects between the anchor and the attached object, correct?
I do not need that, even though it would maybe be more accurate, I just wanted to make a simple rope swinging with a bit of math
Or is using hinge joints the easiest way?

[leaden ice]

many hinge joints would require me to make a string of objects between the anchor and the attached object, correct?
That's the typical approach yes
I do not need that, even though it would maybe be more accurate, I just wanted to make a simple rope swinging with a bit of math
Sounds more like a rigid pendulum than a rope then. In which case you can just do ONE hinge joint

[polar marten]

I just wanted to make a simple rope swinging
there are lots of good unity assets that tackle this problem

[wintry crescent]

paid ones, unfortunately :/

[wintry crescent]

I'll play around with that then, thanks

[polar marten]

yeah i would roll with a paid one

it's complicated

there's no "just" and rolling your own

obi rope is pretty mature

[wintry crescent]

this isn't exactly a project for paid stuff
and my budget is very tight rn, so I can't really afford spending on unity assets :/
especially with the conversion rate of my currency to usd

[polar marten]

i understand yeah

i don't mean to discourage you

have you explored https://www.google.com/search?client=safari&rls=en&q=github+unity+rope+system&ie=UTF-8&oe=UTF-8

[silver void]

How do you folks handle chaining transient modifiers together? An example would be MovementSpeed which can be modified by powerups, the "sprint" button, equipment the player is wearing, etc. Since these things modifiers are transient (I expect them to change often during the course of the game) and numerous, I'm trying to design an easy-to-maintain system which can reliably apply modifiers.

The system I've prototyped is a list of delegates related to the attribute being modified. Each delegate represents a modifier and it is identified by an enumeration. A list of the active modifiers, identified by their enumerations, iterated through to determine the current value whenever a modifier is added/removed. For example, one delegate would multiply the current value by 2, another would add +1 to the base value, and a third would divide the current value by 2. This turns the determination of current state into something of a functional mathematical problem instead of embedding it elsewhere in the game logic, and it also provides a mechanism for checking active states for problems that are simple enough that they don't require a full-blown FSM with transitions and what not. I do see a few disadvantages. however, and I'm wondering what other folks do.

Thanks for any response!

[leaden ice]

basically something like:

float baseValue;
HashSet<AdditiveModifier> additive;
HashSet<MultiplicativeModifier> multiplicative;

public float EffectiveValue => (baseValue + GetSumOfAdditiveMultipliers()) * (1 + GetSumofMultiplicativeModifiers());```

then you Add/Remove modifiers as needed

you can make a float cachedValue too, and only calculate once when adding/removing a modifier

[silver void]

Fantastic! That's almost exactly what I have. I was wondering if I was overcomplicating things in an attempt to achieve what I thought was an intuitive solution, but seeing that you do something similar puts me at ease. Thanks for the response!

[hollow junco]

Is there any way to have 2 functions with the same name and same arguments types and order but implemet 2 diffrent logic on the same class ?

[late lion]

Why HashSets? My first instinct would be to have a sorted list where each modifier can specify a priority.

[maiden breach]

but addition and multiplication are associative commutative* always get those mixed up

[leaden ice]

This was quick and dirty but HashSet to facilitate efficient arbitrary addition and removal operations

If you use sorted list then when you remove you have to do so by the priority as the key? That's funky

anyway this implementation is commutative so order doesn't matter

[rain minnow]

no, can't have two methods with the same parameters. you need to have different parameters, especially if each method does smth different . . .

[hollow junco]

So what else can i do do acheive this ?

[rain minnow]

have different parameters for each method . . .

the real question is what does each — method — implementation do?

[maiden breach]

why you trying to tie two different implementations to the same method name? trying to confuse someone?

[rain minnow]

@hollow junco if they do different things, they should have two different names. the parameters can be the same if you want . . .

[hollow junco]

Because they implement a function with that specific name@in the base interface. But in the class this function behaves diffrently depending on some circumstances

[leaden ice]

if (someCircumstance) {
  // something
}
else {
  // something else
}```

[rain minnow]

then check the circumstance and call the class method . . .

[hollow junco]

Yea that was my thought but its gona be “alot of those so i thoguht sth might be better than if or switch

[leaden ice]

how on earth would the program know which one to call if they have the same name and same parameters?

[hollow junco]

I was asking to see if there is some@magic somehwhere 😂

[leaden ice]

no magic.

[rain minnow]

i was just thinking this . . .

public void SomeMethod(MyType myParam)
{
    if (circumstance)
    {
        this.SomeMethod(myParam);
        return;
    }

    // Non-circumstantial stuff ...
}

[late lion]

They are commutative respectively, but it does matter whether you add or multiply first.
(1 + 2) * 3 = 9
(1 * 3) + 2 = 5
And Praetor made the assumption that all addition should happen first, and then all multiplication, but I don't see why that would be a given.
Shouldn't you be able to get a modifier that adds a +1 after all other modifiers?

[leaden ice]

Again my example was a quick and dirty thing I threw together in like 15 seconds lol

naturally you'd tailor the implementation to your actual requirements

Shouldn't you be able to get a modifier that adds a +1 after all other modifiers?
Maybe your game needs this, maybe it doesn't.

[rigid island]

still considered cross-posting to do so

[velvet trail]

Hello, I´m currently having an issue with raycast and colliders. My player´s colliders are so big that they´re in the way of the raycast. And I wanted to ask if there´s a way to make that raycast ignore the players Collider ? Thanks

[ocean quail]

Okie dokie

[late lion]

A fair point, I must have misread the example you gave. In hindsight, I guess you were mainly showing the "baseValue field" and "EffectiveValue property" approach as the solution, with the two HashSets as just fluff to get that point across.
The field and property approach seemed obvious to me, so I focused on the wrong part.

[rigid island]

ofc there is a LayerMask just seriliaze it in inspector, inside the raycast signature you will add it, add a layer and put player in Player layer it should take care of it

[velvet trail]

so it should look like this ?

[granite glen]

Does anyone know how to check if an AssetBundle is cached before attempting to download it?

[rigid island]

no not at all

you want player excluded it shouldn't be part of LayerMask for the ray

you want Every other layer but the Player layer

[rigid island]

[SerializeField] private LayerMask allOtherLayer

if(Physics.Raycast(... , allOtherLayer)

[velvet trail]

oh riight. Got it 😄 I thought that the layer should be player only. I changed it in the inspector and it´s working now 😄

Thank you !

[rigid island]

if you want to do exclusively ignore layer and not worry each time you add a layer to update this serialized struct

you can only put player inside and do playerLayer = ~playerLayer

playerLayer = ~playerLayer
if(Physics.Raycast(... , playerLayer)

[velvet trail]

Ok, I´ll probably use just that one layer. But Thank you.

In Parse(), can you print the json string (or at least the first 100 characters of it or so) to make sure the json is what you expect coming in?

[languid saddle]

(sorry for the bad presentation, im on mobile phone)

[rigid island]

ok so resizing is what confused me, You want the pattern to stay the same size but tile

[languid saddle]

Sorry for my explanation, yes

[crystal holly]

https://hastebin.com/share/tuqahezowe.typescript

[rigid island]

you'd have to change manually the tiling option in the material

when you resize an object you're also stretching the UVs

hence the stretch look

[languid saddle]

So i cant do it in player?

[rigid island]

You could yeah , you have to access the material and as the object stretches you change the tiling

[languid saddle]

ok, so what sould i search to get a tutorial?

[maiden breach]

Ah I see what youre saying. I thought you meant priority within separate lists

[rigid island]

yeah probably https://docs.unity3d.com/ScriptReference/Material-mainTextureScale.html

or you can try ProBuilder, i believe it has options where you can keep the UV stretch-independent

[languid saddle]

Ok, thank u :)

[crystal holly]

so i am not just being stupid again? 😄

[zinc parrot]

With the RayTracingAcclerationStructures, is there a way to have a TLAS or top level acceleration structure?

[crystal holly]

ah and i just noticed that the parsed values change everytime i run it

[swift falcon]

I have attached three instances of a basic custom sound randomizer component to a weapon of mine. I have a fourth script that does everything else whenever I fire the weapon.

How would I get the weapon to play a sound from each of those sound randomizer components upon firing the weapon?

[rain minnow]

get all of the components then iterate and play a sound from each of them . . .

[swift falcon]

And how would I have it distinguish between the three of them?

Does GetComponent fetch all components under the listed name?

[rain minnow]

well, you shouldn't have more than one of the same component on a GameObject. they should be placed on children . . .

[swift falcon]

Oh.

Ok.

In that case that'd change things... 🤔

[rain minnow]

GetComponent is for a single component. use the plural version to get multiple components . . .

[swift falcon]

I'll come back later.

[rain minnow]

if it doesn't matter which custom sound component plays first, then it's nota problem . . .

[rain minnow]

or, you can create an array on the 4th script and manually drag each custom sound component (from the inspector) into separate slots of the array to get the correct reference . . .

[swift falcon]

I can do that with components?

🤔

[river wigeon]

Could someone help me figure out why the UI looks fine in the editor but not in the build?

The 2 players tags should be next to each other like the editor

[rain minnow]

sure . . .

[polar marten]

not really a coding question but try to uncheck low resolution aspect rations in your free aspect dropdown, then experiment with different view sizes.

[river wigeon]

This is what my UI looks like

[river wigeon]

ok, I'll try

yeah it looks weird when I change the aspect ratios

found the option

child force expand

unticking height has fixed 👍

[swift falcon]

i'm accessing my data class on my Manager singleton, which works fine except for when i open the gameobject in the inspector, where it lags a lot due to how much data there is/ how many fields there are, what are some solutions to this?

[swift falcon]

It works, thanks! 😄

[rigid island]

don't make monolith classes

anything above 300 lines, already doing too much in one class

not sure if it relates to your issue though

[dim whale]

That's arguably subjective to each individual case.

[rigid island]

I guess so

[dim whale]

How many fields are there?
How powerful is your computer?

[dim whale]

It's a good guideline, though.

[rigid island]

Yeah mainly, just makes it easier to debug as well

[stiff tide]

This is the function/method I'm having a problem with:

public Sprite SearchDownloadCardImage(string cardName)
    {
        try
        {
            Sprite result = Resources.Load<Sprite>("Card Images/" + cardName);
            if (result != null) return result;
        }
        catch
        {
            Debug.Log("Failed to find '" + cardName + "' in the Resources file.");
        }
        return DefaultImage;
    }

When the card is created, it calls this method.

public void FlipOrShow(string flipDirection)
    {
        string cardName = cardNamePair;
        if (isSecondPairImage) cardName = cardNameTop;
        Sprite CardFront = SearchDownloadCardImage(cardName);

        Sprite currentSprite = gameObject.GetComponent<Image>().sprite;

        if (flipDirection == "Front")
        {
            gameObject.GetComponent<Image>().sprite = CardFront;
        }
        else if (flipDirection == "Back")
        {
            gameObject.GetComponent<Image>().sprite = CardBack;
        }

And when you hover over the card, it's meant to display it's own image onto a larger card. (A hover and zoom mechanic). It's also supposed to display it's parent or child.

public void OnMouseHoverEnter()
    {
        ZoomedInSprite = gameObject.GetComponent<Image>();
        ZoomCardTop.GetComponent<Image>().sprite = ZoomedInSprite.sprite;
        // [It searches for it's pair here.]
        if (cardPair != null)
        {
            ZoomedInSprite = cardPair.GetComponent<Image>();
            ZoomCardPair.GetComponent<Image>().sprite = ZoomedInSprite.sprite;
        }
        else
        {
Debug.Log("Found Neither!");
            string cardName = cardNameTop;
            if (isSecondPairImage) cardName = cardNamePair;
            ZoomedInSprite.sprite = SearchDownloadCardImage(cardName);
            ZoomCardPair.GetComponent<Image>().sprite = ZoomedInSprite.sprite;
        }

[rain minnow]

It lags? How many fields/much data is in the class? 🤔

[stiff tide]

But when that exception happens, when it can't find a parent/child that's a card object, it has to call that original method again. Doing so causes the original card image to change. Even though the card's own image is never touched in the hover display method.
https://gyazo.com/2d2db811d80a6554b8b8d82f38285fb0

[dim whale]

If you right-click the script component bar, and select 'Properties', a separate window will pop up for only that component. (Perhaps this lags less).
A more direct approach is to expose less fields at the same time.
NaughtyAttributes has an attribute for Foldout groups (https://assetstore.unity.com/packages/tools/utilities/naughtyattributes-129996)

public class NaughtyComponent : MonoBehaviour
{
    [Foldout("Integers")]
    public int firstInt;
    [Foldout("Integers")]
    public int secondInt;
}

https://raw.githubusercontent.com/dbrizov/NaughtyAttributes/master/Assets/NaughtyAttributes/Documentation~/Foldout_Inspector.gif

[stiff tide]

Actually, you were right. As a test, I just replaced the method call with a default image. The default image shows... and also replaces the card's original image.

I changed only one part of one line:

public void OnMouseHoverEnter()
    {
        ZoomedInSprite = gameObject.GetComponent<Image>();
        ZoomCardTop.GetComponent<Image>().sprite = ZoomedInSprite.sprite;
        // [It searches for it's pair here.]
        if (cardPair != null)
        {
            ZoomedInSprite = cardPair.GetComponent<Image>();
            ZoomCardPair.GetComponent<Image>().sprite = ZoomedInSprite.sprite;
        }
        else
        {
Debug.Log("Found Neither!");
            string cardName = cardNameTop;
            if (isSecondPairImage) cardName = cardNamePair;
            ZoomedInSprite.sprite = DefaultImage; // This is the line I changed.
            ZoomCardPair.GetComponent<Image>().sprite = ZoomedInSprite.sprite;
        }

[swift falcon]

so i should split my data class into a bunch of different classes? i'm not sure how i'd serialize and deserialize that, and it'd be annoying needing to reference different data classes for every little thing

[stiff tide]

Which gives this result:
https://gyazo.com/3870095768000891a42b861cf5386cbb

[rigid island]

This is entirely up to you , there is no "Right way"
But I typically breakdown a Game Manager into smaller managers instead of 1 giant class

[swift falcon]

oh yeah no i have several managers, but just one data class

[rigid island]

I send events to a singleton EventManager so i dont couple anything

[swift falcon]

since writing that i tried changing to just a singleton Data class not on the Manager class, which i guess reduced the lag since i can't even open it in the editor now lol

[swift falcon]

oh that's really cool i'm gonna get that for sure

[swift falcon]

a lot
pretty damn good

[dim whale]

Would you mind screenshotting this to give us an idea?
Lagging inspector doesn't sound right. Which Unity version is this on?

[swift falcon]

2021.3.5f1
i already moved it to its separate class and changed every reference so i can't really screenshot

i can send a save file though which would give a decent idea

[rain minnow]

How much? I do find it hard to believe a single class lags the editor . . .

10, 100, 200, etc.?

[swift falcon]

save file is 70k lines lol

[swift falcon]

that's not code it's a save file

[dusk apex]

Sounds like a mess. What have you got in there?

Ah, alright.

70k lines or file size?

[swift falcon]

lines

file size is 892kb on a fresh save

the biggest perpetrator is the cell data which saves the 20x20 grid and the contents of the cells

[rain minnow]

you still use a paste or bin site to post code, it's a json file. no one will download links . . .

[swift falcon]

without it it'd be like less than 1-2k lines

it's over the pastebin file size limit

[rain minnow]

wow, never seen that before . . .

[swift falcon]

i'll paste it with the all cell data removed except for one

https://pastebin.com/P3ph0KD1

[dusk apex]

See a lot of redundant data (blank fields) being recorded

[swift falcon]

which specifically?

[dusk apex]

Practically the same data for many objects:

Data that doesn't need saving or that are always default should just not be serialized?

[swift falcon]

1: idk how to not serialize it
2: if i don't serialize it then i'll need to check for if it's not there and create it when i do want to use those stats

[dusk apex]

Unless this sample's a coincidence..

[swift falcon]

nope

every object that can hold the seed class has its seed serialized even if it's null

lol

it works fine in saving and loading but now you might see why the inspector was lagging lol

[rain minnow]

do you need to see the data class from the inspector? makes sense to just check the save file . . .

[swift falcon]

it's useful for debugging but no i don't need to, that's why i moved it to its own class

[dim whale]

Right-click the Inspector tab, and you can switch to Debug mode, which shows everything.
To reduce the amount of serialized fields visible in the inspector, use the attribute [SerializeField, HideInInspector]

[dusk apex]

A fold out group could reduce clutter - not sure if it'll reduce inspector delay.

[dim whale]

Linked him NaughtyAttributes for that earlier

[swift falcon]

oh i meant i moved it to its own non monobehaviour class since i can't deserialize to a monobehaviour

[rain minnow]

i thought it was already a c# class, not a MonoBehaviour . . .

[swift falcon]

yeah but earlier it was on the Manager monobehaviour

now it's not on one so i can't see it in the inspector

it's fine like this tho not a big deal

[lyric wadi]

that data would gzip down probably 98% since it has so much repeated data

[swift falcon]

i'm not sure what gzip is but yeah compressing with 7-zip cuts the size by 16 times

[dusk apex]

That's what I was getting at. It seems a lot of fields were saved for no particular reason.

[dim whale]

GZipStream

[dusk apex]

Lot's of empty strings and zeros

[lyric wadi]

you zip and unzip it as part of the save process after serializing to json

[swift falcon]

i could not save the cellData that's just the default state, but the object i care about saving most (Seed) i want to save all of its stats because they might be accessed in the future, and checking to see if it has the stat or not and then creating it would be more of a hassle than the few kb i save

[swift falcon]

oh interesting i'll look into that

[lyric wadi]

trying to pastebin an example

[lyric wadi]

https://pastebin.com/NutgV6Ge

[swift falcon]

what's the byte[] data parameter supposed to be?
this is in the LoadData() function

string json = reader.ReadToEnd();
Data.Instance = JsonUtility.FromJson<Data>(json);

[wintry crescent]

I'm so annoyed
I have an object that has locked all movement and rotations blocked by rigidbody constraints (except for y rotation) but when I apply upwards torque to it, it still rotates a little bit along the other axes
why is it doing that?

[lyric wadi]

when you compress it you get a byte[] array, I was saving that to disk with File.WriteAllBytes, and File.ReadAllBytes to read the file gives the byte[] array that you pass to get the json string back from the compressed bytes. compressed = bytes, you take the compressed bytes to get back decompressed string of json

[swift falcon]

oh gotcha

try that rq

[zinc parrot]

With a raytracingaccelerationstructure how do you have it so objects inside it can move? UpdateInstanceTransform doesnt seem to work

[swift falcon]

can't really test this right now since i made the change to the Data class, now it fucks up initialising everything when there isn't a save file to start with

[lyric wadi]

right on, that's just the process for gzip if you wanna use it, for me it took my saves from 100kb to 7kb from all the repeated data

[swift falcon]

damn

[pearl swallow]

This might be a more advanced question, but I just want to ask it here in case it isn't. So I have an enemy (GameObject) that fires a projectile towards the player's position due to following the player's position. How might I be able to adjust the height and/or speed so that the further the player goes, the further the projectile will go? This is how the current script works to instantiate and then add force to the projectile:

GameObject poison = Instantiate(poisonProj, poisonSpot.position, transform.rotation);
poison.GetComponent<Rigidbody>().AddRelativeForce(Vector3.forward*500);

[swift falcon]

what do you mean the further the player goes?

[wintry crescent]

you want the speed of the projectile to increase depending on how big the distance to the player is?

[pearl swallow]

Yes

I do have a distance registry:

 playerDistance = Vector3.Distance(player.position, transform.position);

        if(playerDistance <= plantRange && plantStatus == 0)
        {
            transform.LookAt(new Vector3(player.position.x, transform.position.y, player.position.z));

            if (fireCountdown <= 0f)
            {
                GameObject poison = Instantiate(poisonProj, poisonSpot.position, transform.rotation);
                poison.GetComponent<Rigidbody>().AddRelativeForce(Vector3.forward*1000);

                fireCountdown = 10f / fireRate;
            }
            fireCountdown -= Time.deltaTime;
        }

But it is mainly in use to regulate that it fires within a certain range and to look at the player.

[wintry crescent]

calculate the distance to the player, take its magnitude, then multiply the speed with that magnitude and some additional factor
you can also lerp between two values (min speed max speed) based on the distance and some max distance that you expect

[wintry crescent]

you have the distance
you can start by changing the *1000f into, for example, *100f *playerdistance

or something

and go from there

[pearl swallow]

So vector.forward*(100f *playerDistance)?

There's meant to be more of the stars-

God dammit discord

[void anchor]

return recur(recur(x * 3)); can anyone explain when a method replays in a method

[pearl swallow]

GameObject poison = Instantiate(poisonProj, poisonSpot.position, transform.rotation);
poison.GetComponent<Rigidbody>().AddRelativeForce(Vector3.forward*(100f *playerDistance));

Like this?

[cosmic rain]

Recursion. There's not much to explain.

[wintry crescent]

instead of writing * you can write \* to make it ignore the star for italics

[pearl swallow]

Oh

Neat

[wintry crescent]

yea something like this

[pearl swallow]

Thanks

[wintry crescent]

then you can look up things like Mathf.Lerp, Mathf.Clamp and other things

[void anchor]

ik what currsion is but when it call itself twice in the same method

idk what that means

[wintry crescent]

see what could be useful to you

especially Mathf.Lerp - you're gonna end up with this one, I almost guarantee it

[pearl swallow]

Alright.

I'll see if I can figure it out, otherwise I'll be back here.

[cosmic rain]

It doesn't mean anything special. It's simply is called twice.
As for why it's done in that particular case, no clue. Need to research the code.

[pearl swallow]

Would a vector3.up also help it if its moving further away too?

In case terrain is uneven?

Or would turning off gravity or lowering gravity help?

[lyric wadi]

you can add vector3.up to the vector3.forward, you'll probably want to multiply it by magnitude as well in parentheses Vector3.forward + (Vector3.up * magnitude) * force * magnitude

[wintry crescent]

if it's at the same level as the player, you can turn off the gravity

[pearl swallow]

If anything I might try to flatten the Terrain a tad.

[lyric wadi]

is this like a turret

[pearl swallow]

But I'll make sure to look back if I want to mess with it.

Kinda

It's a plant monster that shoots poison

So, effectively a turret

I'll mess around and play with it a little

I don't need it complete by tomorrow, just doing milestone presentation for the project.

I got next week free due to spring break

So I'll be deep diving if I don't get distracted with video games

*too distracted

[wintry crescent]

hi, is there a way, from inside the abstract MainMenuScreen class, call Register<ClassDerivingFromMainMenuScreen>() if my code looks like this?

public abstract class MainMenuScreen : MonoBehaviour
{
    private void Awake() 
    {
        Register<???>();
    }
    protected void Register<T>() where T : MainMenuScreen
    {
        MainMenuController.Instance.RegisterScreen<T>(this);
    }
}

I want every instance of a class that derives from mainmenuscreen to register itself automatically, while providing its own type

[zinc parrot]

Is there a way to have a #define in one file affect multiple other files without changing the settings?

[buoyant crane]

Couldn’t you do Register<MainMenuScreen>()?

[wintry crescent]

nope - I need the actual derived type, because I later use as a key to a dictionary

[mossy snow]

why provide T at all? Register(this), get the type via GetType() inside RegisterScreen

[wintry crescent]

I ended up doing a screen.GetType() in the MainMenuController class

[wintry crescent]

yep, that's how I ended up

[mossy snow]

I'd probably make Awake protected and virtual rather than have a separate Register method too, Awake is easy to shadow accidentally and then your register system will silently break

unless the derived type calls Register itself directly, which would be easy to forget

[jolly dune]

https://gdl.space/jinuvefaxu.cpp how do I combine these two things together?

the problem is the if statment is asking for x or y

[wintry crescent]

yeah, I was wondering how to prevent overriding it by accident

is there a better way than just protected virtual?

it just squiggles a line right now, but does nothing about it otherwise

[mossy snow]

you could use clamp rather than an if statement, but this logic is weird. If either x or y velocity magnitude exceeds maxMovespeed, you set BOTH velocity directions to the max? So if I'm moving 1.1 units in x direction and 0.1 units in y direction with a max speed of 1, my new move speed should be (1, 1)?

[faint brook]

anyone know how to make drawray and drawlie stop flashing

Hi - is there a way to load a scene, using LoadSceneAsync, but hold off the actual... enabling of the scene?
I want to load the scene, and when it's ready I want to do some things, then when I'm done - switch to it immediately, without loading or any further delay

[vagrant agate]

So.... I implemented a basic custom swipe. My dilemma now is, I have a few horizontal scroll containers on some of the views. I wonder what the best way is to detect if their finger started in any of the scrollable containers so it doesn't change screens on them.

[dusk apex]

Example, if you were determined to use generics... https://hatebin.com/pyzlldjjys

[cosmic rain]

Track the container that the pointer down event was registered in and reset it on pointer up.

[vagrant agate]

Since there are multiple gameobjects in the horizontal containers, it would seem I would need to traverse up the hierarchy to see if the parent is a scrollable container using something like EventSystem.current.currentSelectedGameObject? I really only need to know if the Phase.Began happened in one of the horizontal scroll containers.

[cosmic rain]

Not sure what you mean. I'd just have a script on each container, catching the pointer events and reporting to some kind of Manager up the hierarchy. And before allowing any dragging in the container, ask the manager if it's allowed.

[vagrant agate]

I was able to get it working using this. It detects if the mouse is over a scrollview by tag and stops my swipe code from running.

var pointerEventData = new PointerEventData(EventSystem.current) {position = touch.position};
        var raycastResults = new List<RaycastResult>();
        EventSystem.current.RaycastAll(pointerEventData, raycastResults);

        if (raycastResults.Count > 0)
        {
            foreach (var result in raycastResults)
            {
                if (result.gameObject.CompareTag("ScrollView")) return;
            }
        }

id say its probably expensive but my players wont be on this screen very much

[cosmic rain]

Getting pointer data from the even system like that is crude, but if it works for you, then ok.🤷‍♂️

I'd use IPointerEnterHandler and it's friends.

[dusty steppe]

How do I put a variable from a script to a panel on my camera that changes (ammo)

[oak plover]

how would i go to making a attack animation when i have basic anim's for movement? i have basically no idea how to to do 2d anims lol

no i dont think i do

i dont know yet i want to see what is better for the game

bet thx mg

[oak plover]

m sorry what
im so confused
ignore flip and update animationstate but in my animation i have a bool named isAttacking from all states of anim if you press mb 0 it attacks so i made a pub void end attack. in side making "isAttacking" to be false. in the attack animation i set an event at the end making it so it stops the animation and going back to idle using a transition of isAttacking = false. the event is set up and this is too its staying in a constant loop.

hey could someone help me with an issue

[swift falcon]

?

[solar kettle]

I am having an issue with an editor script

[swift falcon]

What kind of issue?

Can you specify a little more

[solar kettle]

Its a lot to describe in chat

can I call you?

[swift falcon]

Uh not rn im in the bus going to school

[solar kettle]

Its from Natty's youtube series

I have a script that can be placed on some objects but not the one I need and it seems to delete the component right after I add it

[swift falcon]

Hm idk tbh

Just wait until someone thats knows a little more about this can help you

[cosmic rain]

What's interactable.useEvents?

[solar kettle]

Its ok I figured it out

Its a custom editor script for interacting with objects

[stable shore]

pls help me

projects don't open

[solar kettle]

did u change the file path for your projects?

[plucky inlet]

not really coding related. but try to remove it and readd it in unity hub

ok I wont

after I fix my issue I will type in appropriate channels

[fallen knot]

Hi guys. I'm willing to pay someone to show me how to convert game object prefabs that have already been placed into my level, into Terrain Trees, while keeping their original locations, rotations and scales.
I'm a noob and have spent all day trying to figure this out. Is there a Job channel somewhere?

[potent sleet]

!collab

bot is taking a nap..

#📖┃code-of-conduct find them here @fallen knot

[fallen knot]

Thanks!

[latent latch]

https://docs.unity3d.com/ScriptReference/TerrainData-treeInstances.html

Try that

https://docs.unity3d.com/ScriptReference/TreeInstance.html

[potent sleet]

I think they got the opposite

they have prefabs and want to switch with terrain trees with same pos/rot/scale?

[latent latch]

Actually, that class seems rather useless. Doesn't really give any GO info.

beyond pos/rotation

[plucky inlet]

Well you can use this to place trees with the module based on the list of GOs transforms

Basically you would instantiate the trees https://docs.unity3d.com/ScriptReference/Tree.html based on that I guess

[latent latch]

Oh, right so the terrain also changes the size and such as well too, so you can't really get all that information from the GO.

so you get the prototype and grab the size the terrain is changing it to.

[plucky inlet]

Not sure what you mean? He just wants to create trees on the already done terrain while using his gameobjects transform values. Nothing on the terrain is changing besides the terrainData holding the trees

[latent latch]

Oh, rofl. Ok, yeah probably an easier problem in this case then.

[potent sleet]

yeah hiring is prob overkill lol

[latent latch]

https://docs.unity3d.com/ScriptReference/TerrainData.SetTreeInstance.html
Well, this would seem like the func to use, but then there's this line

Sets the tree instance with new parameters at the specified index. However, you cannot change TreeInstance.prototypeIndex and TreeInstance.position. If you change them, the method throws an ArgumentException.

So, basically useless unless I'm understanding it wrong.

[plucky inlet]

I understand this function as replacing an existing tree with a new one but keeping its values persistent cause you cant change it.

[latent latch]

Ah, that's probably it then

[fallen knot]

What i want has to be very specific. Its not about instantiating my prefabs, its about getting them into the terrain tree system.
Because afterwards im converting the trees in the Terrain system into a plugin - but they need to be in the Terrain tree system first.
Im doing a conversion from Unreal to Unity

[latent latch]

Either way, you cant just init a tree onto the terrain, you need to assign it to the terrain first to give it the prototype. So, there's this extra bit of overhead.

optimization reasons I'd assume

[fallen knot]

The reason I'd be willing to pay for it, is because time is money, and im not adept at using Unity. Im barely even a beginner.
But Im a pro at Unreal, and i have a bunch of my Unreal assets on the marketplace that need converting to Unity.
I have an employee already doing this, but this the last issue in the pipeline that i need to resolve

If someone already knows how to do this, it'd make sense to just shoot through 10-20 bucks to just have the issue resolved, rather than spending countless hours trying to learn how to code.
Ive already spent 3 hours trying to search a solution to this online

I'd rather spend my time earning money doing what i do best, and just pay someone who is good at unity to solve it for me 🙂

[latent latch]

May be better off looking at the paid assets unity store has to offer

[fallen knot]

Im trying to sell on the Unity store. I cant use other peoples work

Im an Unreal Asset developer looking to convert my Unreal projects to Unity, to sell on the Unity store

actually, i see what you mean

If its a once-off thing and the code isnt in the product itself, that would be fine

[orchid bane]

I use this but the result position is only 1 unit far from the camera, how do I fix it?cs public void OnDrag(PointerEventData eventData) { transform.position = _cam.ScreenToWorldPoint(eventData.position) + _posDiff; }

How can I make projectile move like in the video, initially spread out, and then flying to the cursor position. I know how to make projectile fly to the cursor position straightly but I dont know how to make the spread out things and the curve movement.

[plucky inlet]

looks a bit like vfx graph and world simulation space, so emit particles stay on their world position. Or what exactly do you mean by spread out?

[void fog]

like magic missile?

[eager cliff]

some projectile is flying to the top at start and some are flying downward

[plucky inlet]

Ah, got it. So you need a start and endpoint and with those you gotta spread out the local values of the particles by using like a bezier animation curve that starts and ends at 0 and in the middle the spread as you like. from there you can randomize the spherical spread with that curve values to get the desired spreading effect.

You could also let them spread to the middle distance and then modify the particles from there to move towards the target back with simple lerping

[eager cliff]

its a animation thing? but not the actual gameObject movement?

I want the projectile hit enemy in the middle of flying if they touch the enemy

[plucky inlet]

So imagine you have a default line from A to B, that is your moving particle system or vfx origin. And with the time from start (0) to end (1) you can lerp the spread to be bigger at 0.5 and almost 0 at time 1.

[eager cliff]

so I want to code it but not just animate

[plucky inlet]

I would start using a particle system and read about how to access those and how to modify their position depending on the lifetime

Particle is always flying from point a to point b + the offset depending on the distance to the target.

[crystal holly]

hey guys, i'm pretty desperate at this point.. i'm trying to parse a json string containing mesh data. but for some reason i'm getting completely nonsensical values for all the vectors (vertices, positions..) the ones for the triangles are correct that's why i'm suspecting that something is being handles wrong with the floats..
my json string looks like this:
https://pastebin.com/snRZ5bck
but my parsed objects in unity look like this:

[crystal holly]

what is also super strange is that everytime i run it in unity the parsed on the vectors change although my json stays the same

[plucky inlet]

How do you load your json and put it into class?

[eager cliff]

yes

[void fog]

you'd need to fire the projectile from N different translations

eg im pointing north, east, and west

once each projectile is fired, you'll need to basically "track" it back to target

to do that, you still do movment like normal but you're turning and other stuff

[crystal holly]

https://pastebin.com/SnBVbS5U

[plucky inlet]

Please switch to newtonsoft first and see if that fixes your issue

[eager cliff]

I find a keyword "slerp". It's a upward curve, how do I get the left, right, and bottom slerp

[void fog]

i think thats just unity's wrapper for newtonsoft.json

[crude mortar]

slerp interpolates from any rotation to any other rotation,

[plucky inlet]

It is not

[void fog]

under the hood i assume it's using JsonSerializer.Deserialize<T>(string)

[plucky inlet]

its a super barebone not usable version of json

[void fog]

weaksauce

why even have it then? lol

we dont even use newtonsoft anymore in .net core

[void fog]

that makes it feel like a roll your own JToken parser lol

[eager cliff]

what "interpolates" mean

[void fog]

moves?

[eager cliff]

so its always curving upward?

[void fog]

i think its more like finding points

eg. you have a dot at 0,0 and 10,10 and are connected via a curve

using interpolation would help you find points on that curve?

[plucky inlet]

JsonUtility for example does not support Properties, only fields.

[void fog]

oh thats super gross

there has to be a use case for it though

[craggy veldt]

STJ works in the latest version, no need to use the turtle newtonsoft

[void fog]

Right... STJ ftw

[plucky inlet]

unity is just nostalgic in keeping their own json utility in the software 😉

[plucky inlet]

What STJ? And what latest version, like the stable one?

[void fog]

System.Text.Json

[plucky inlet]

Ahhh, my bad 😄

[orchid bane]

How do I move a MonoBehaviour from one GameObject to another?

[plucky inlet]

Well that makes it even easier just to use the Serializer right away, just forget about util and newton 🙂

[void fog]

yup, built in from the start

[plucky inlet]

You want to move the component?

[void fog]

JsonConvert.Deserialize<T>(...)

[craggy veldt]

it is not, you'd need to download the Nuget package and make the linker works for both WebGl and IL2CPP

[plucky inlet]

Now that you write it, I actually used it in my latest project without even thinking 😄

[crystal holly]

that actually did the trick! thank you!

[orchid bane]

Yeah, I want all the references to it to be kept

[craggy veldt]

still much much better than the turtle newtonsoft

[void fog]

Convert vs Serializer

i still get them mixed up

[plucky inlet]

Ahh, got it, guess another dev set it up back then in the project. thanks for clarification and how to implement it 🙂

[plucky inlet]

as we discuss, you can also use System.Text.JSON if you want and want to set it up, but newton does fine too for the most part.

[void fog]

if your .net version is 6+, you really should be using STJ

[crystal holly]

would there be any advantages?

[void fog]

STJ is so much faster

[craggy veldt]

small memory footprint too

[void fog]

because of fewer allocations

optimized code and a vastly improved framework

[plucky inlet]

Does it make a difference for one time calls tho?

[void fog]

its best to just get into the habit of using STJ

[plucky inlet]

A tutorial as a shortcode here on the server would be handy or on vertx website tool 😉

[void fog]

https://learn.microsoft.com/en-us/dotnet/standard/serialization/system-text-json/how-to?pivots=dotnet-8-0

Here's what it should link to

and i did have it backwards damn it lol

JsonSerializer is STJ, JsonConvert is Newtonsoft

var options = new JsonSerializerOptions { WriteIndented = true };
            string jsonString = JsonSerializer.Serialize(weatherForecast, options);```
juice

oh now this is an interesting tidbit...

youd still have to convert those bytes to a string which might still be that 5-10% you're saving =/

whats the point?

[craggy veldt]

Note that you can still use STJ in the older Unity versions, it's just won't take the benefit of Span<T>

[plucky inlet]

Maybe using utf8 directly would benefit as you would not convert it, not sure. Someone gotta have a usage for that I guess 😄

[void fog]

byte[] == char[] == string

this just gives you the encoding code instead of the actual string character

i guess that would be useful for when you are doing binary reads...

[thin aurora]

Did they end up wrapping the very first version of it? Because it's total shit

[void fog]

i dont know... its not STJ so i dont care 😛

[thin aurora]

Pretty sure STJ is not Unity compatible unless you manually add it?

[void fog]

if you're running .net core, you have STJ

[thin aurora]

There is a Newtonsoft Unity package

[thin aurora]

Sir this is a Unity server

[void fog]

the code-behind is C#

[thin aurora]

.NET != Mono

[void fog]

...

System.Text.Json has linux and macOS native methods

.net core is cross platform compatible

[thin aurora]

So how is this Unity compatible again?

[void fog]

because of the target framework of it's underlying language?

[thin aurora]

https://learn.microsoft.com/en-us/dotnet/api/system.text.json.jsonserializer#applies-to
Unity implements .NET Standard 2.0 using Mono

[plucky inlet]

From 2022 on you can use System.Text.String, so it can work

[thin aurora]

My question is how you expect a serializer that does not explicitly target .NET Standard to work in Unity

Unless, of course, I am mixing up the versions

[void fog]

.NET Standard is a formal specification of .NET APIs that are available on multiple .NET implementations. The motivation behind .NET Standard was to establish greater uniformity in the .NET ecosystem. .NET 5 and later versions adopt a different approach to establishing uniformity that eliminates the need for .NET Standard in most scenarios. However, if you want to share code between .NET Framework and any other .NET implementation, such as .NET Core, your library should target .NET Standard 2.0. No new versions of .NET Standard will be released, but .NET 5, .NET 6, and all future versions will continue to support .NET Standard 2.1 and earlier.

It's in .NET Standard 2.0 only for compatability with multiple target frameworks

.NET 4.6.1, .NET 4.8, .NET Core 2.1, 3.1, .NET 5/6/7/8/etc.

[thin aurora]

So how exactly would you make STJ work in Unity? Does the namespace exist in versions 2022 and later?

[void fog]

when your app compiles, it compiles against a target framework

.NET Standard is more of a "middleware" between versions for compatability

i reference .NET Standard libraries from my .NET 6 project and that has access to System.Text.Json

and newer versions of C#, etc.

[plucky inlet]

I know you blocked me, but maybe you hit that close button 😄 It should be a thing in 2022

[thin aurora]

And this works without manually importing the dlls as plugins?

[void fog]

System.Text.Json has been a thing since .NET Core 3.1

You dont need additional nuget packages, correct

System.Text.Json is part of .NET inherently

[thin aurora]

That's different

[void fog]

just like Console.WriteLine

[thin aurora]

I know STJ is not a Nuget package

I'm talking about it being an actual part of Unity as of 2022

[void fog]

using System.Text.Json;

its not unity... its C#

unity just uses C#

[plucky inlet]

Just testing it right now

[plucky inlet]

So forums said, it was, but it is not. You can still use the nuget xml hackaround way loading all the dlls, but its not part of Unity for now.

[void fog]

?

in your code files where you put your logic, you cant put using System.Text.Json?

[plucky inlet]

System.Text.JSON is NOT part of unitys builtin NET version.

[craggy veldt]

^

[plucky inlet]

So you either have to hackaround, use newtonsoft or never look at json again 😄

[void fog]

STJ isnt compiled against .net standard 2.0

that means they restrict you to only standard 2.0

...

[craggy veldt]

just put the link.xml in your assets and make sure it won't get stripped when compiled

[thin aurora]

Isn't this literally what I said?

[void fog]

i think STJ would indeed add a dependency on having the .net 3.1 or later runtime installed

[thin aurora]

This is why I asked it

STJ is not in Unity

[void fog]

I didnt know unity locked things down like that

[thin aurora]

Welcome to Unity

[void fog]

im not writing things in the unity library

why do i need to stick to net standard 2.0?

im using the libraries... thats it

[craggy veldt]

2.0 is sorta neutral standard, 99.999% it would work with newer versions

[void fog]

theres no restriction from me working in a net 6 project and referencing .net standard 2.0 libraries

[plucky inlet]

Okay, I guess we just have to accept for now, the majority will use newtonsoft for now on Unity projects and from what I have seen, it works fine for everyone including me 😄

[thin aurora]

There is nothing wrong with Newtonsoft

[void fog]

except performance lol

[thin aurora]

People prefer STJ because it is buildin

But what they don't realise is that STJ does not actually compile for .NET Standard

[thin aurora]

As mentioned here

And Mono supports .NET Standard, not .NET 5,6, whatever

So therefore my confusion as to why STJ is being suggested 😄

[vague slate]

I have 4 directions represented by simple vectors:
Vector2.up/right/left/down

I also have a quaternion which also represents such direction.
Question:
How do I rotate one of such directions with given quaternion?

For example if I have direction up (0,1)
and quaternion of angle (0,-90f,0)
I want to get (-1,0) result

[plucky inlet]

I think you taking edge cases as an example most people would not even run into if you dont do heavy reloading of data (which would be more of a problem of data handling then json itself)

[thin aurora]

There is a Newtonsoft Unity package and it's literally the same as STJ for more people

[void fog]

I dont see why i wouldnt just have my project target .net 6, give me access to STJ and reference the ,net standard 2.0 libraries

[void fog]

https://inspiration.nlogic.ca/en/a-comparison-of-newtonsoft.json-and-system.text.json

[plucky inlet]

you want to rotate the vector with your quaternion as offset?

[thin aurora]

I'm sure if it were that easy they would have ditched Mono by now

[vague slate]

I guess

[void fog]

the only reason they have mono is because of the graphics for linux and such

[craggy veldt]

you're getting it wrong.. for convenience yes... for performance? no.. newstonsoft is slow for bunch of reasons and allocates lots of memory

[void fog]

mono works on net 6

[thin aurora]

When I say "for most people" I mean those who don't case as much for performance and edge cases. I'm sure bubba that started the conversation does not really care if Newtonsoft is much slower than JSONUtility 😄

[void fog]

looks like its the other way around

[thin aurora]

I would appreciate STJ in Unity but as of right now you will have to deal with the mess that ended up because .NET was not cross platform back in the day

[void fog]

that jsonutility was their own homebrew

[void fog]

Yeah, i've been working with C# for far too long to know that it shouldnt be a limitation... I just need to look more into this unity side of things because under the hood it's still just a C# project compiled with roslyn...

[plucky inlet]

Did you try to just multiply it with your quaternion? cs vector = Quaternion.Euler(0, -90, 0) * vector;

[void fog]

the problem isnt .net... the problem is unity

unity is still using legacy mono functionality because linux still hasn't got a standardized graphics api

thats the only reason why unity is coded to still work against framework

framework is already or almost at EoL...

[plucky inlet]

Should this discussion be worth a thread to not clutter up the help channel? Just suggesting

[void fog]

threads have a tendency to kill conversations (which this is)

its not one person asking for support or anything like that

there's no one person in focus

[cold parrot]

Unity uses mono (still) because .NET core has no api for hosting it on top/inside of a separate runtime (unity engine). They are working on that though.

[void fog]

hosting it . . it being what?

[cold parrot]

The whole native code runs the .net runtime in the same process is not possible, out of the box, with .net core

[void fog]

what native code?

[cold parrot]

The engine

[void fog]

the engine is written in C# and C++... DllImport and such lets you call the C++ from C#

i dont agree with what you're saying at all...

anything you can do in framework you can do and more, better with newer versions

unity hasn't been rewritten to work with the new language specifications... it's not .net lacking or missing functionality

its unity missing and lacking

[plucky inlet]

I think we got your point. I would suggest open a thread to keep on going about this thing, cause we are away from coding issues more into general unity implementation of features

[void fog]

this is general coding discussion

in #archived-code-general...

we dont need a thread

[plucky inlet]

you do you

[cold parrot]

Something being technically possible doesn’t mean it’s immediately useful and all relevant situations are automatically solved. A lot of work has gone into making unity work with mono, these 17 years of development and design have to be recreated for core, and many past assumptions need to be changed and this has sweeping effects on a very large codebase

[void fog]

i think there is some miscommunication and/or misunderstanding

i can take a C# debugger and debug a unity game...

[cold parrot]

Parts of it

[void fog]

which parts can i not?

the C++ unless i have that debugger set up as well

[cold parrot]

The native parts

[void fog]

and the symbols

[cold parrot]

Which you don’t have

[void fog]

define "native parts" and please lets not use such ambiguous terms

lets be specific here please

[cold parrot]

The proprietary code that you have no source access to, or any debug symbols or documentation

[void fog]

for unity?

have you heard of dotPeek?

they dont even obfuscate it

that was part of my job at Curse... stripping assets from games like Hearthstone

the point is i can generate symbols for it and hit it with a debugger

[cold parrot]

great

Enjoy your life

[plucky inlet]

You just want to convince everyone from you being right here, this is not leading anywhere tbh and not helping anyone with any question about general coding concepts in Unity

[thin aurora]

Sir I just wanted to inform you that STJ is currently incompatible with Unity 😢

[void fog]

Im not on a mission or anything... just trying to clarify... this was a stem from a base conversation that got derailed

[modest ether]

Does anyone know if there's a way to stream chunks of a big city mesh, not terrain? Or a way to divide one big mesh into smaller pieces? One way is to divide it yourself manually and stream chunks with sectr or world streamer.

[cosmic rain]

You could split it into smaller meshes manually and "stream" it with addressables.

[cold parrot]

I would suppose that any such partition would have to be manually authored to be useful in a particular project. Generic approaches exist ofc (somewhere), but overall they are usually in conflict with the way performant game worlds are constructed (compact individual ‘rooms’) where no non-compact thing/object/model stretches far outside the immediate vicinity/frustum of the camera

[plucky inlet]

you could also generate LODs if thats helping you stream fewer polygons, but why do you want to split it up in general? Does the user see it one after the other, or should it be dinstance based, what is the case?

[cosmic rain]

Maybe it's a trillion triangles or something 😅
And they need it to run on mobile🤔

[plucky inlet]

Isnt that a thing for occlusion culling then with as you said manual separation of the meshes? We will know it eventually 😄

[modest ether]

It should be split so it can be streamed. All the game objects in the chunks should activate/deactivate with the chunk
