[heady iris]

right, since you'd get two variants that are unconditionally taking one side of the if / else branch

but a branch on a uniform doesn't diverge: every single thread is going to take the same path

[rotund girder]

hey can someone help

im a new scripter and snippets arent showing up for me on vs

[heady iris]

do you mean you're getting no autocomplete or error highlighting at all?

[leaden solstice]

I don’t think generated code can regard it? You can still change the value on runtime

[heady iris]

I mean that, when the shader program is executing, every thread will take the same path

because the branch is based entirely on a uniform

[spring creek]

Follow the guide you brought up in #💻┃code-beginner

[rotund girder]

autoComplete. Look at the ss I have attached. I was expecting it to suggest me the "useGravity" attribute of the rigidbody i have mentioned above in the code

[rotund girder]

alr

[knotty sun]

show the declaration of rb

[rotund girder]

here it is but i believe im fixing it now. i had to install something in unity called vs something

[leaden solstice]

Hm, guess that right, but I guess I would prefer using static branching for consistency

[heady iris]

the problem is that this causes Shader Variant Hell very quickly

[leaden solstice]

True, it's multiplying every time you add something like that sure

[serene stag]

where are you coding without vs.

[spring creek]

They are likely talking about the package. That is also likely not the issue

[serene stag]

oh ok.

[leaden solstice]

But I think the case you mentioned is quite specific (and relies on some internal detail), so I doubt it could be a general tips and practices

[heady iris]

i mean, skipping a calculation if I'm not using a feature is pretty standard

[leaden solstice]

Usually involves using other resources tho. I do like to see benchmark on that

[vagrant knot]

I'm trying to create a gravity switcher mechanic and I'm failing to use quaternions/rotations to reorient and remap player input to handle movement.
Would someone hop in 5min call so I can show current state and ask questions?

[spring creek]

Very unlikely someone will get on a call. You should show what you've tried and maybe someone can help here

[heady iris]

Show your code and we can probably help.

[spring creek]

Oh, also don't cross-post

[rotund girder]

visual studio code

I jus downloaded visual studio

the download keeps failing though

😭

[rigid island]

this isn't a code question

also !install

[tawny elk]

When Unity fails to install checklist

• Make sure you have enough space including on C: drive.
• Check that it's not being blocked by antivirus/security programs.
• Look through the logs for a real reason why the setup fails they are pinned [here](#💻┃unity-talk message).

If you still have issues, perform a clean install in another location:

• Install the Hub and Unity in a non-system drive or a clean new folder in the root of C: drive.
• Failing that use the recovery Refresh option or reinstall OS entirely then repeat the previous step.

[rotund girder]

sorry

[leaden solstice]

So I see that you can just define dynamic_branch keyword in this case which consist with other keywords and change easily when you need to make it static branch
Only downside is probably that you can't set it with MPB?

[heady iris]

I can't do that in the shader graph, unfortunately

I guess that a uniform is basically equivalent to a dynamic_branch at that point

[leaden solstice]

Yeah that's just lacking the feature

But it is equivalent

Or use custom function and code it.. lol

[slim gate]

public static Dictionary<Id, Sprite> LoadTexturesFolder()
{
    Dictionary<Id, Sprite> sprites = new Dictionary<Id, Sprite>();

    string folderPath = Path.Combine(Application.persistentDataPath, Data.TexturePath);

    if (Directory.Exists(folderPath) == false) { return sprites; }

    string[] filePaths = Directory.GetFiles(folderPath, "*.png", SearchOption.AllDirectories);
    foreach (string filePath in filePaths)
    {
        Texture2D texture = LoadPNG(filePath);
        if (texture != null)
        {
            string fileName = Path.GetFileNameWithoutExtension(filePath);
            Sprite sprite = Sprite.Create(texture, new Rect(0, 0, texture.width, texture.height), Vector2.zero);

            sprites[new Id("scourgefall", fileName)] = sprite;
        }
    }

    return sprites;
}

private static Texture2D LoadPNG(string filePath)
{
    Texture2D texture = null;
    byte[] fileData;

    if (File.Exists(filePath))
    {
        fileData = File.ReadAllBytes(filePath);
        texture = new Texture2D(2, 2);
        texture.filterMode = FilterMode.Point;
        texture.LoadImage(fileData);
        texture.Apply();
    }
    else
    {
        Debug.LogError("File not found: " + filePath);
    }

    return texture;
}

So I have the above to load in some .png files at runtime. In the editor I can go into the Sprite Editor and edit: Custom Physics Shape and Secondary Textures. Is there a way to assign/ apply these somehow directly in the code at runtime too?

I want to:

• apply a secondary texture to a loaded sprite with a specific name like "_Emission" etc.
• Ideally also set a custom physics shape somehow per code

Any way to do this?

[leaden ice]

Physics shape:
https://docs.unity3d.com/ScriptReference/Sprite.OverridePhysicsShape.html
For applying a secondary texture, that wouldn't have to do with the texture itself but with the Material you use in your SpriteRenderer or however you're rendering the thing.

[slim gate]

Oh, thanks alot!
I think I realize what you mean; The material has 2 Textures exposed as properties in the shadergraph: For example. "_MainTex" and "_Emission". Then I can just apply these 2 properties with the 2 textures I want. The textures themselves arent related at all and I set them seperately in the material.
I had the wrong Idea of how it worked i think, Is the above correct?

It just confused be cause in the editor I would just set the "_Emission" as a secondary of the "_MainTex" and not assign it to the material too
I guess the engine does that step for me when its the secondary texture with the proper 'id'?

[old linden]

What is the obvious reason I can't reference my VectorCache class from a MonoBehaviour class? 😂
I have no Errors to resolve

[knotty sun]

your VectorCache is in an unreferenced dll

you can reference Assembly-CSharp from Assembly-CSharp-Editor but not the other way round

[somber nacelle]

why is VectorCache in the editor assembly?

[old linden]

I have no idea why it's there 😂

[somber nacelle]

did you perhaps put it in a folder called Editor?

[knotty sun]

it's in an Editor folder ?

[old linden]

Ah. I am extending a downloadable tool and didn't realise when I dropped it in. It certainly is. Thanks a bunch

[heady iris]

yeah, if you don't add your own assembly definitions, Unity puts anything in an Editor folder into a separate Editor assembly

[old linden]

Is there a way to keep it in the Editor folder, but have it in the standard assembly?

[somber nacelle]

why does it need to be in the Editor folder?

[knotty sun]

simple answer, no

[old linden]

It's only used for Editor tools

Ok no probs Il just move it

[knotty sun]

obviously not

[old linden]

What?

[knotty sun]

well if it was supposed to be editor only and you are referencing it in Assembly-CSharp then it is not Editor only or you have a serious design problem

[old linden]

The underlying tool has design problems unfortunately

[knotty sun]

then, as long as VectorCache does not contain any editor only code or references, best to move it out of the Editor folder so it becomes available to both

[leaden solstice]

Adding an assembly definition can make you have that under Editor folder

But now then your Editor folder is not for Editor

[heady iris]

You'll just have to make sure that you don't have any references to it when building the game

You can have the entire script inside an #if UNITY_EDITOR block

[old linden]

It's not worries I just moved it. The class that requires it stores editor data for Editor and Gameplay functionality and rewriting that would be a massive undertaking

[dawn nebula]

Finally, working splines. Just tried it on 2022.3.31f1

[knotty sun]

did you try in 6 preview as well? it should be the same code

[dawn nebula]

nah

[somber nacelle]

the fix was pushed in 6000.0.4 and 2022.3.31 so it should work in either

[vital oracle]

For grid based games what is the common practice to store and manage data associated with the grid.

Say the level map is a 2D 100x100 grid. You would want to store the grid position of the player, enemies, items/interactables, obstacle and walkable grid positions, etc. And also be able to change the positions of these elements and access their associated data easily, i.e. enemies moving each turn or a randomly generated level so the walkable and obstacle positions need to be changed.

[leaden ice]

In my view it depends on whether the data is expected to be dense or sparse

If the data is dense, it usually makes sense to use a 2D array, e.g. GridSlot[,]

If the data is sparse, I would use something like Dictionary<Vector2Int, GridSlot>

[vital oracle]

How would you describe dense and sparse?

[leaden ice]

What I mean by dense and sparse is, will the grid be mostly empty? If it's mostly empty, the data is sparse.
If most or all of the spots will always have some data associated with them, it is dense

The nice thing about the Dictionary is we don't need to store any data for empty slots. This makes it more memory efficient than the array when dealing with a sparse grid

But the Dictionary comes with slightly higher costs for adding and retrieving elements, so if the grid is dense, we may as well just use the 2D array since we will need to hold all that data anyway.

[fleet tide]

Do you know why i have 2 circles ? It's really weird

[vital oracle]

Hmm, well I wasn't talking about a specific game I was making, more to start planning the data structure of one.

Lets say of the level grid there would be at least 30-40% of the grid positions that would be obstacles and structures, the rest would be sparse with maybe a few enemies that move around the map and some items to interact with.

I've done a game with grid movement, but just used a collision system for movement as I didn't really need any data storage. But I'd like to instead not use collisions and just use the underlying grid data to place characters and move them.

[gray mural]

Well, you gotta at least show how you create them

[leaden ice]

That sounds pretty sparse to me, but it's in the range where it would probably be similar either way.
Anyway you can accomplish that with either data structure I mentioned above.

[leaden ice]

Your code isn't handling the case when the dog is direcetly in the opposite direction

[fleet tide]

Oh yeah sorry ahah

[fleet tide]

https://gdl.space/elabuzekew.cs

[fleet tide]

Simply ?

[vital oracle]

So either way you would either store a data element in a 2D array or a dictionary. In this case what would you store, a struct?

Would the data be stored in the struct just be the position and a reference to the gameobject associated with that grid position? Or would you store the gameobject data needed (enemy data, etc) directly in the struct.

[fleet tide]

Its work, thanks !

[gray mural]

You don't have 2 circles, it's just that the circle is drawn even when the enemy is not visible to the player.
The z position returned by the WorldToScreenPoint method is the world units from the camera, so if the enemy is not visible to the player, which rotates the camera, then its z position is smaller than the one of the camera.

[fleet tide]

Oh i see thanks for explanation !

[gray mural]

The enemy should just be detected when the camera sees it. This means its z position is greater and in camera's range

[plucky holly]

What is wrong with unity's rotations? I have a cube and I have a decal that's is rotation depending on the rotation of the cube no matter which face is facing up so when I put it down, the decal is align with the cube. but when the y axis is facing down, it acts weird.

[plucky holly]

this is what I want

And this is what it does when the Y axis is facing down

I use a very simple script for it

[somber nacelle]

https://unity.huh.how/quaternions/members

[plucky holly]

the other why I tried was this

        _angle = vector3.angle(vector3.up, transform.right);
        _rotation = transform.localeulerangles;
        upf = mathf.abs(vector3.dot(vector3.up, transform.up));
        rightf = mathf.abs(vector3.dot(vector3.up, transform.right));
        forwardf = mathf.abs(vector3.dot(vector3.up, transform.forward));

        up = upf > rightf && upf > forwardf;
        right = rightf > forwardf && rightf > upf;
        forward = forwardf > upf && forwardf > rightf;

        if (up)
        {
            _angle = transform.localeulerangles.y;
            vector3 _rot = transform.localeulerangles;
            _rot.x = 0;
            _rot.z = 0;
            decaltransform.eulerangles = _rot;


        }
        else if (right)
        {
            quaternion targetrotation = transform.rotation;
            targetrotation.y = transform.rotation.y;
            targetrotation.x = 0;
            targetrotation.z = 0;
            decaltransform.rotation = targetrotation;
        }
        else if (forward)
        {
            quaternion targetrotation = transform.rotation;
            targetrotation.y = transform.rotation.y;
            targetrotation.x = 0;
            targetrotation.z = 0;
            decaltransform.rotation = targetrotation;
        }

and this time the problem was only this Z

[knotty sun]

still trying to modify quaternion properties. DONT

[plucky holly]

the reason I have so many if and they are same is I was trying something else

[somber nacelle]

#archived-code-general message

[knotty sun]

When you do Quaternion->Euler A->Quaternion->Euler B. A and B will almost certainly not be the same

[leaden ice]

That part depends heavily on your game and what a grid slot can "contain"

YOu might also have a "terrain layer" which is probably pretty dense and an "items layer" which maybe has enemies, chests, items, etc which would be sparse.

[plucky holly]

I see it. it doesn't fix my issue

[somber nacelle]

show what you tried

[plucky holly]

it still doesn't make sense that it only acts weird in one axis

[heady iris]

because you're mangling a quaternion's four components

the behavior is not intuitive

[plucky holly]

Vector3 _rot = transform.localEulerAngles;
_rot.x = 0;
_rot.z = 0;
decalTransform.eulerAngles = _rot;

this is what I first tried

this one acts weird on Z axis up or down

[plucky holly]

so what should I do?

[vital oracle]

Would it be impractical to store all of these different game elements in one grid? Say have a struct that points to a gameobject reference.

[leaden ice]

It owuld be quite practical

I would recommend rather than GameObject though, to have a component like GridElement which goes on all of the different things

[leaden solstice]

This gonna be complex as your box can be rotated to any direction so you cannot rely on any single axis

I assume you want your decal to follow the axis that is most upward

Other option would be just locking Y axis

[earnest pawn]

I'm making a tower defense and I have a tower I would like to do something whenever each round ends (give the player bonus money). I have a level manager game object that handles spawning enemies/updating rounds and such, and I could just have the tower look for a change in the round variable each frame but that sounds like an awful design choice. I don't want the level manager to have to have an array of all of this type of tower or anything like that, so is there a way I can set up a callback across objects? Essentially have my tower look at the level manager and whenever it updates the current round, it runs it's function.

[leaden ice]

Have the level manager fire an event when the level ends

have the tower listen to the event

[old linden]

To mimic a single axis and maintain whatever values are on the other axis try:
transform.rotation = Quaternion.Euler(transform.rotation.eulerAngles.x, otherTransform.rotation.eulerAngles.y, transform.rotation.eulerAngles.z)

Or to nullify the outlying axis', replace them with 0

OverlapCollider not finding colliders

[fleet tide]

Hey ! Someone know if it's difficult or not to create a launcher for my game ? I want create it for upload new version of my game to my friend without download it again ^^

[plucky holly]

yes thats what I want

first I tried to check which axis is on top and get the rotatins depending on that

but that didn't work as expected

[plucky holly]

it was the last thing I tried after eulerAngles when it didn't work

[lean sail]

There are tutorials out there on how to create one. Regardless they'll have to download it though, which is something your application might try to do automatically. If you plan on publishing this for the public, stuff like Steam already handles this since it basically is a launcher

[fleet tide]

Its not free for steam so that why i try to find a way to have it free , its for manage update and info to everyone

[lean sail]

It's hard to answer on its difficultly, this mainly depends on you. I just suggest researching how others make it online and decide for yourself if you're capable. There is a reason that steam exists, but also consider that MANY people do not like when games have their own launchers

[fleet tide]

Okey thanks you for the answer

[pulsar holly]

Whenever I try to rotate my gameObject, it spawns a clone of it. Here's the code: https://pastecode.io/s/09qwryx7 https://pastecode.io/s/z4i3hhyd

[rigid island]

don't think it would be possible to clone an object without Instantiate

also don't crosspost

[pulsar holly]

I instantiated

[rigid island]

where?

[pulsar holly]

https://pastecode.io/s/nwottz8w

[rigid island]

so you have 3 different scripts, you might want to explain what exactly these scripts do

typically can tell what goes on, but here I'm genuinely confused what is even going on. Very messy

is this some tetris type of game?

[naive swallow]

So, you're spawning a new one when dropSet is -3. That's in PuyoScript so let's see where that's changed--

Yeah, no I'm out I'm not trying to make sense of this

this is an absolutely unmaintainable mess and will be basically impossible for anyone else to make sense of it

Not to mention the fact that you are repeating everything over and over again

[rigid island]

was about to say, lots of redundant code

[naive swallow]

to the point that you are literally setting all of these booleans to false twice in a row inside of your horrifically repeated code blocks

I say this with absolutely no hints of irony, and as a 100% serious suggestion: All three of these scripts should be deleted and remade from scratch

Do not reference any old code, make them out of whole cloth. This is a slapdash mess of bandaids and no longer resembles programming in its current state

[somber nacelle]

this is a code channel. do you perhaps mean to ask in #🖼️┃2d-tools ?

[steep knot]

oops

[weary swift]

Yo ! Do you know any famous/good written 3D games created in Unity that have the code open source ?

Lmao I'm asking here because I searched google and I didn't find anything meaningfull

[rigid island]

really cause I find plenty

[weary swift]

I'm asking for recommendations here not for a list... Therefor humans are better at this than google...

[rigid island]

the human thing to do is doing your own research like all of us do

If you think so

[rigid island]

[weary swift]

OMG ! For example I didn't know about this, you could just answer with this but putting a google reaction seams better...

Unless you're trying to just rip code, I doubt you'll really find what you want in open source code.

[rigid island]

um yeah if you're lazy thats on you

[somber nacelle]

"guys where can i find open source projects"

doesn't know about searching on github

[rigid island]

fr

[weary swift]

Lmao that's crazy to think like that

[somber nacelle]

yeah, i mean who wouldn't do literally the bare minimum to research open source software

[weary swift]

Just want to see how people write code, and some precise part about handling animation end

[lean sail]

My statement still stands. You really wont find what you're looking for. A lot of large games will mostly be unreadable because code will be scattered across. Editor tools might not be included, or stuff like animation events may be used.

Unless you dedicate a decent amount of time to actually learning the codebase

[weary swift]

Ok

[full canopy]

transform.localRotation = Quaternion.identity;
transform.localRotation *= Quaternion.FromToRotation(-attachTransform.forward, transform.forward);```
the code above has different results depending on if attachTransform is a child or grandchild of transform. Why?
attachTransform's world rotation does not change, only whether it is a direct child or a grandchild.

unless I'm wrong, transform.forward returns a world-space vector no?

[leaden ice]

Can you show the hierarchy?

Yes transform.forward is world space

[full canopy]

grab point (attach transform) in grandchild v.s. direct child

[leaden ice]

transform is Kraber Magazine?

[full canopy]

yes

[leaden ice]

And what are the two different results you see?

[full canopy]

child v.s. grandchild (held at same angle)

one's basically backwards for some reason

hold on

i uh

may be incredibly stupid

yeahhhh

sorry @leaden ice

{
    transform.parent = selectingObject.transform;
    transform.localRotation = Quaternion.identity;
    transform.localRotation *= Quaternion.FromToRotation(-attachTransform.forward, transform.forward);

    //transform.localRotation *= Quaternion.Inverse(attachTransform.localRotation);

    transform.position = selectingObject.transform.position + (transform.position - attachTransform.position);

    if (useRigidbody)
    {
        attachedRigidbody.isKinematic = true;
    }
}
else if (activating)
{
    transform.parent = activatingObject.transform;
    transform.localRotation = Quaternion.identity;
    transform.localRotation *= Quaternion.Inverse(attachTransform.localRotation);

    transform.position = activatingObject.transform.position + (transform.position - attachTransform.position);

    if (useRigidbody)
    {
        attachedRigidbody.isKinematic = true;
    }
}
else
{
    Drop();
}```
what i wrote was in the if (selecting) portion

but the interaction is in the if (activating) portion so it just never actually changed anything

on a second note though, what is the best way to get the local rotation between 2 objects if one is not a direct child?
Quaternion.FromToRotation(-attachTransform.forward, transform.forward) did not work as i thought it would and is not consistent either

transform.localRotation *= Quaternion.Inverse(Quaternion.Inverse(transform.rotation) * attachTransform.rotation);
turns out this is the actual answer. Ive tried so many things involving quaternion.inverse and never thought about using it twice like that

[serene stag]

why would anybody keep it open source if they have made something really good. you need to try to achieve it.

[dire marlin]

my game has a save system and on some of my beta tester's builds the new game button doesn't work and the load game button freezes the player's character in the wrong place

i'm not sure why this is happening

[lean sail]

sounds like you need to get to adding more logs and seeing whats happening for real. What you've described is what the beta tester probably said, as the dev you need to dig deeper. For a button not working, id first check to see if its covered by anything. Maybe they are on a different resolution, where things just shifted enough so that the button is covered by some invisible thing they are clicking instead.
For the other part you mentioned, this isnt enough information to suggest anything. Check for errors possibly, check to see if input is being registered. What is "freezing in the wrong place"?

[dire marlin]

its the code

[lean sail]

this couldnt be more vague. Surely theres something more you've reached in your conclusions like if the data gets logged and is correct

you are giving very little information to go off of

first i know by a video that the player CAN interact with the new game and load game button

new game doesnt work though when clicking

[lean sail]

id assume you probably want binary writer.

[lean sail]

🤷‍♂️ so does this mean you've done 0 debugging and just watched a video of someone click buttons?

[dire marlin]

I have done some debugging

The buttons are interacted with but no errors

ig ill switch to player prefabs

[lean sail]

you need to start debugging a lot more about what specifically isnt working. Narrow it down to an exact line of code that isnt running, or is running with the wrong value. Im not sure how to make this more clear, that the fact a button isnt working isnt gonna help you find the issue

youve basically only said "button isnt working" then showed completely random code, that i cant even be sure is related to the button.

[dire marlin]

this function is literally linked to the button

when you press this button this function starts

[lean sail]

Ok so you are claiming that the function starts, but also 10 minutes ago "new game doesnt work though when clicking". Do you see why i am telling you to debug more? You are assuming what is happening in code. What specifically doesnt work? What line of code? Figure this out then itll be more clear at least what the issue is

[dire marlin]

im trying to debug but the problem isnt replicated on mine or most of my other testers computers

[lean sail]

Which is why you get their logs, not your own where everything works fine.
https://docs.unity3d.com/Manual/LogFiles.html

best case is you would be able to get access to their setup, and setup a development build where you can breakpoint exactly whats happening. Though if this isnt possible, you'll pretty much have to rely on log files and videos

Hi guys, I'm having trouble with InputAction.GetBindingDisplayString

The sample uses legacy text for their key displays

But on mine, with it being TextMeshPro text, it somehow bugs and fails to display correctly

[sleek bough]

Is debugging printing out correctly?

[pastel patio]

It shows a missing char after the key

Yep

I'm certain that it's TMP messing up

[sleek bough]

Then you just need to make sure UI element large enough to fit

[pastel patio]

I don't quit get what you mean...

TMP has missing char issues

Like trying to display A/u25A1

[sleek bough]

Test by putting text manually. UI has options that wrap text to next line that can obscure, etc.

[pastel patio]

U+25A1 is whitesquare

Which cannot be displayed

Showing a box

[sleek bough]

Ah, if it's a missing character you need to add it into font asset

[pastel patio]

Uhm no, that's not the case.

On Legacy text, it displays as A

On TextMeshPro text, it displays as A \u25A1

And on debug, it displays as A as well

Even if I added the character to the font, it's a character that wasn't supposed to be shown in the first place

[unkempt pebble]

hello, i am working with inventory and i have problem can someone help me? if you equip an item and then move the item in your inventory or drop it, it is still equiped

[pastel patio]

In my game there's an event on the inventory script that broadcasts slot changes

[unkempt pebble]

interesting

[pastel patio]

Unimportant for your usecase but I divide my inventory up into InventorySlotGroups

[unkempt pebble]

oh

[pastel patio]

Each slot group has an event telling slot changes, including change index

[sleek bough]

Not familiar with the problem. There are some search hits on similar problem on forums, search u25A1. You also might want to repost entire full question in #📲┃ui-ux . Someone might know there.

[pastel patio]

This one -> public Action<Itemstack, int> OnSlotModify;
Itemstack = The new itemstack
int = the slot index

There're legit many ways to do this tho, mine's just an example

[pastel patio]

Thank you

[static matrix]

how could I detect if an object is "behind" another in 2d
like if I was to make a perpendicular line to an objects transform.up and check whether another object lay in front of or behind it

[gray thunder]

check layers

[static matrix]

????
how would layers matter, this is for position

[gray thunder]

ah

[knotty sun]

if you are using an orthographic camera you can always use position.z for this

[static matrix]

well im aware of how I can check for in front or behind in general for 3d space
im looking for in front or behind relative to a vector

[fleet tide]

Hey !

So i have an problem when i build my game :

In unity, when i run, i spawn and everything is good

When i build, and start the game, i'm blocked in menu and i need to click on server and on client

Why and how to fix it ?

PS: I use Fishnet and PlayFlow

[vagrant blade]

Make a development build and look at the console for errors. Nobody can begin to 'why and how' fix this question with less information that you have.

[fleet tide]

This is the view in unity when someone launch the game but dont click on server and client :

[fleet tide]

Oh okay thanks , i will try it

[knotty sun]

do not cross post

then remove it from here

because people like you require it when they don't follow the rules

[vagrant blade]

This is a community server, the active community members know and help enforce the rules.

Don't be upset because you were told to also follow said rules. Crossposting is not allowed.

And no, visual scripting shouldn't have severe performance. It's just code in the end.

[knotty sun]

hmm, not sure, I would love to see the code generated by visual scripting

[vagrant blade]

Yeah, I don't actually know what happens behind the scenes

I'd assume it's not that big a difference. Or hope anyway, assuming you have a clean board

[knotty sun]

I've made node based systems and they are damn difficult to be made efficient

I will give the guys at Bolt the benefit of the doubt

[thick terrace]

unity visual scripting is all reflection-based, there's no codegen yet unless that changed in unity 6

there are third-party ones like unode that do codegen

[knotty sun]

if that is the case then there will be very significant performance implications

[heady iris]

I'm pretty sure I've seen errors caused by code generated by visual scripting...

[thick terrace]

there is generated code as part of the package, but just node boiler plate for the editor iirc

[heady iris]

ah, like how code is generated for other graphs (to define the nodes themselves, that is)

[thick terrace]

yeah, the graphs themselves are just unity assets

[heady iris]

I remember seeing a Generated folder while helping someone with a weird shader graph problem

[thick terrace]

you might find it's not a problem for your game, like for my use case it's fine because we're not using it for anything high performance, just various simple game logic

if you do hit performance problems, i believe unode comes with a tool to convert unity visual script graphs to its own format, so you could maybe keep that as a backup option

[serene stag]

yes for some.

yes few new features applied.

[heady iris]

I guess I'd say it's composition-based.

You don't create more specific kinds of GameObject

you attach components to game objects

[oblique spoke]

Entities/GameObjects with components (EC) is probably the way to communicate it.

[modest ether]

Does anybody have experiences with builidng packages? I having a small roadblock and I dont know how to fix it. I know that my code works but when I want to create a package with it Im missing dependencies and stuff
I wanna make a package out of my custom Visual Scripting Nodes but Its like I cant use the using of Unity.Visualscripting inside the script

It works outside of the package just fine

[heady iris]

The name collision is very annoying!

[leaden ice]

If you have an Assembly Definition you need to add any package references you are using to it.

[modest ether]

how?

[leaden ice]

in the inspector for the assembly definition

[modest ether]

yeah okay I think I did that for Mathematics

[leaden ice]

Yup, same process

[modest ether]

but there is no deffinition for Visual Scripting

[leaden ice]

Yes there is

[modest ether]

where?

[leaden ice]

https://docs.unity3d.com/Packages/com.unity.visualscripting@1.9/manual/index.html#installation

com.unity.visualscripting

[modest ether]

what?

thats all the defintions I have

[leaden ice]

Is the Visual Scripting package installed in your project?

[modest ether]

Yeah

[leaden ice]

As a package? Or as an asset in the asset folder?

[modest ether]

yes package

it works with the same script which is not inside the package

also I imported like the mathematics in the assembly definition so yeah

you mean this part right?

[thick terrace]

if for some reason the picker isn't showing it, you can probably drag and drop the asmdef from the visual scripting package into an empty slot in the list, or edit the asmdef as json and just type it in

[leaden ice]

Yeah that^

[modest ether]

its empty haha

for whatever damn reason

I just dont get it whats happening lol

[thick terrace]

well, there's your problem i think lol

🤔

[modest ether]

yeah but freaking why

[thick terrace]

maybe just reinstall it then

[modest ether]

its always installed

you cant remove it

[thick terrace]

is it installed as a dependency from some other package?

[late lion]

You can remove it, but it comes installed by default.

[leaden ice]

yeah yoiu can it's a normal package in the package manager

[leaden ice]

This is what I see

[modest ether]

wow I freaking hate the package manager

[trim rivet]

How can I get the distance between an object in the scene view and the scene view camera ? 👀

anyone know

[modest ether]

I just dont have it

I can use it

but I cant add the definition...

[leaden ice]

https://docs.unity3d.com/ScriptReference/SceneView-camera.html

You should be able to get it from there yeah?

[modest ether]

Creating a new Project its there

why

anyway thanks for helping

I go the route with the new project

[pliant sapphire]

Hello guys I need help, I have this patrolling script in which enemy will go from point to point and when it comes to last point it will just stop. I want my enemy to go back to the first point and start looping and I also want my enemy to face where the point is because now he will just walk backwards to the point that is at the back of him for example. This is script: https://hastebin.com/share/abuwegolov.csharp

[leaden ice]

Looks like it should loop back to the start based on your current code

Use Debug.Log to make sure current = (current + 1) % points.Length; is running

[pliant sapphire]

Okay

it gives 0 @leaden ice

[thick terrace]

you're reassigning the value in the debug log with that, just do Debug.Log(current)

[pliant sapphire]

okay

[pliant sapphire]

I did that and now it gives value 1 and starts looping

idk how did he start looping now first 3 tries he didnt loop

[glacial tundra]

I haven't touched Unity in a while, but wanted to ask if Animator controller is only official path to animating sprites. It looks like the legacy Animation component doesn't actually change the sprite in SpriteRenderer any longer. Surely there is a better workflow for sprite animation that I'm just not seeing.

The goal for me is use a FSM to change out AnimationClips in script without the overhead, and potential runtime errors, of setting up states and transitions in the editor.

These AnimationClips are also getting AnimationEvents generated at runtime, so any method of assigning them would need to respect those events.

[heady iris]

A paid alternative is Animancer

[cold parrot]

You can make a custom animator system using the playables framework

[heady iris]

It's a pretty neat package: you do all of your animation through code.

[heady iris]

And that's basically what it is (:

[cold parrot]

Animamcer is a readymade solution that is built on top of playables, so are mechanim and timeline

[glacial tundra]

Thanks for the recommendation for Animancer. Playables seems super verbose for something as simple as changing the index of a sprite sheet over time.

[heady iris]

you could also just make lists of sprites :p

[glacial tundra]

Yeah, it's hard to understand how something as simple as an out of the box 2d animation system doesn't exist.

The Animation component of old was really straightforward.

[cold parrot]

There is no general problem that is ‘simple’

[heady iris]

the out of the box 2D animation system is the Animator

[glacial tundra]

Well, it is a generic animation system 😄

[sacred pewter]

and anything beyond animator but not quite mechanim is best done DIY in 5 lines of code

[heady iris]

yes, it plays animations

and you can animate a sprite renderer's sprite

[oblique spoke]

Isn't that still there?

[sacred pewter]

it still is and its not even deprecated

[glacial tundra]

It doesn't seem to change the sprite in SpriteRenderer any longer?

I'm in 2022.3.20f1

Also running Debian editor, but I haven't seen any runtime issues because of Linux. There are some editor bugs.

[glacial tundra]

Can you provide more insight on the logic behind those 5 lines?

I honestly thought Animator and Mechanim were the same system.

Based on the documentation, it seems they are anyways.

https://docs.unity3d.com/462/Documentation/Manual/MecanimAnimationSystem.html

[cold parrot]

https://docs.unity3d.com/Manual/AnimationScripting.html

[glacial tundra]

All of this code seems to be specific to blending and additive effects. It's not showing the logic behind adding animation clips at runtime.

[cold parrot]

why don't you just make animation clips from your sprite sheets, put them in an animation component and activate/play the animation you want in a script?

[glacial tundra]

Legacy Animation components do not update the sprite in SpriteRenderer

[cold parrot]

an animation clip change is nothing more than an instant blend

[glacial tundra]

I'm not sure how to say it any differently than the legacy Animation no longer works with sprites.

You can make the clip, mark it as legacy, and attempt to play it with a sprite renderer attached and it will do nothing.

This looks like what I need
https://docs.unity3d.com/Manual/Playables-Examples.html

[heady iris]

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

you could just use an AnimatorOverrideController to swap out animation clips

[glacial tundra]

Thanks for the recommendation. I'm going to take a pass at the Playables and see if it hits all of my use cases. It's great that it doesn't take a dependency on basically an empty asset object.

[gray mural]

Hey, is there any way to simplify it using a single StartSomething method without it being async?

private void StartSomething(IEnumerator coroutine) => StartSomething2(coroutine);

private async void StartSomething2(IEnumerator coroutine)
{
    await MyTask(coroutine).ConfigureAwait(false);

    test = false;
}

private async Task MyTask(IEnumerator value) { ... }

[thick terrace]

what are you trying to achieve? why can't it be async?

[chilly surge]

Use ContinueWith.

[gray mural]

It still doesn't throw an error

[gray mural]

I'm moving through an IEnumerator

[thick terrace]

what about StartCoroutine ?

[gray mural]

It doesn't run in Editor properly

[heady iris]

https://docs.unity3d.com/Packages/com.unity.editorcoroutines@1.0/manual/index.html

there's this fella

I have not used it before

[gray mural]

I know about that, it doesn't work

[heady iris]

cries

[chilly surge]

ContinueWith has TaskContinuationOptions where you can specify for error handling.

[thick terrace]

there should never really be a need to use ContinueWith tbh, async does more or less the same thing with much better defaults

[chilly surge]

But honestly this code looks kind of weird so I'm not sure what the point is.

[gray mural]

I have already tried using it, but its WaitForSeconds is only called in Update, which, for the Editor, is just called when any changes are made

[glacial tundra]

Is this for an editor tool?

[heady iris]

ah, I see

there's no real consistent update cycle at all, is there

The iterator functions passed to Editor Coroutines do not support yielding any of the instruction classes present inside the Unity Scripting API (e.g., WaitForSeconds, WaitForEndOfFrame), except for the CustomYieldInstruction derived classes with the MoveNext method implemented

sad

I presume that a custom yield instruction would only get MoveNext called whenever the editor decides to update

[gray mural]

So, I've tried this, but it doesn't seem to throw an error when it's happening inside of MyTask

MyTask(coroutine).
    ContinueWith(t => Console.WriteLine(t.Exception),
        TaskContinuationOptions.OnlyOnFaulted);

The [initial approach](#archived-code-general message) using await with ConfigureAwait does catch it

[chilly surge]

It's never called?

[gray mural]

The error is not thrown

[chilly surge]

But you can see the error being written to console right?

[gray mural]

No, I don't see the error in the Unity console

It's just that the method stops from its execution

[thick terrace]

does Console.WriteLine do anything in unity? surely you want Debug.Log

[gray mural]

When using the initial approach, it does stop, and the error is thrown

[gray mural]

Damn

My bad

It does print the exception to the console, still, no exception is being thrown when done this way

MyTask(coroutine).ContinueWith(t =>
{
    print(t.Exception);

    throw new(t.Exception.Message, t.Exception);
},
    TaskContinuationOptions.OnlyOnFaulted);

[chilly surge]

You can just throw it yourself or do whatever handling with the exception directly, no?

I mean, ultimately async/await just compiles to a state machine, so at worst you can just look at the compiler output and copy it.

(The whole use case still feels very weird to me though)

[waxen blade]

I have a class with a bunch of different Vector3s, and I want to consolidate it into a single class. However, when I do that, I don't now how to add it into a dictionary.

public class Foo
{
    public class Bar
    {
        public int TestInt { get; set; }
        public string TestString { get; set; }
        public TestPositionData MyPosition { get; set; } = new TestPositionData();
    }

    public static Dictionary<int, Bar> Bars = new Dictionary<int, Bar>()
    {
        { 1, new Bar{ TestInt = 1, TestString = "A", MyPosition.???} },
        { 2, new Bar{ TestInt = 2, TestString = "B", MyPosition.???} }
    };
}

public class TestPositionData
{
    public Vector3 PositionA { get; set; }
    public Vector3 PositionB { get; set; }
    public Vector3 PositionC { get; set; }
}

TestInt and TestString have the correct snytax when adding it to the dictionary. How do I set MyPosition.PositionA, MyPosition.PositionB, and MyPosition.PositionC directly into the dictionary?

[heady iris]

you would need to construct a new TestPositionData there

somethingl ike MyPosition = new TestPositionData() { PositionA = Vector3.one }

[waxen blade]

Now I'm just trying to get the syntax on your suggestion correct.

[heady iris]

Not enough closing braces

[waxen blade]

    public static Dictionary<int, Bar> Bars = new Dictionary<int, Bar>()
    {
        { 1, new Bar{ TestInt = 1, TestString = "A", MyPosition = new TestPositionData() { PositionA = new Vector3(0, 0, 0)  } } },
        { 2, new Bar{ TestInt = 2, TestString = "B"} }
    };

I think I got it.

Thank you Fen. 😃

[heady iris]

Also, you should be able to omit the type name

so just MyPosition = new() { ... }

[waxen blade]

Yeah, it's already cluttered enough as it is so I'll get rid of that.

[fallen ridge]

Any reason why line 71 would return the Element 5 on the first iteration of the for loop?

[heady iris]

you are modifying the prefab itself

that seems weird

You're throwing out the new instance

it it going bye-bye

I bet you draw six cards

[fallen ridge]

I'm not gonna lie idk what im doing here

its drawing the 5

[heady iris]

you're seeing the card that you wrote into cardPrefab in the last iteration of the loop from the last time you ran it

(okay, if we're 1-indexing, then you're drawing 5 cards)

[heady iris]

Do not modify the prefab.

[rigid island]

Instantiate returns a copy of the prefab

[heady iris]

You should store the return value from Instantiate and modify that

[rigid island]

modify the copy

[fallen ridge]

I'm loading the prefab with new info

[heady iris]

Yes, you are!

And it's producing nonsense results

You need to modify the new instance

[fallen ridge]

ahhhhh

i shall return in a timely matter

I'll probably rename newCard at some point but this worked. thank you 😛

[wary dock]

Heya. I would like to make prototype of games like They Are Billions. Any advice on the approach I can take for having potentially thousands of units on screen with collision and such? I recently started checking out DOTS but are there other approaches?

[heady iris]

I need to try that out myself

One thing to consider is to manually draw the enemies instead of using a crapload of individual MeshRenderers/SpriteRenderers

e.g. https://docs.unity3d.com/ScriptReference/Graphics.DrawMeshInstanced.html

oh wait,

https://docs.unity3d.com/ScriptReference/Graphics.RenderMeshInstanced.html

I am not very experienced here, though.

[leaden ice]

ECS is the best but you can get away with a lot by using only bits and pieces of DOTS like the job system and things like compute shaders and DrawMeshInstancedIndirect.

Also I love that game glad to see it mentioned

[heady iris]

yeah -- you can absolutely do hybrid setups

I experimented with a "3 bajillion enemies" game with DOTS

the player was 100% normal GameObjects

[gray mural]

What do you mean by throwing it myself? That's exactly what I'm doing though? Throwing an error within ContinueWith just doesn't seem to do anything

[gray mural]

It's just that I'm moving through an IEnumerator with asyncs

private async Task MyTask(IEnumerator value)
{
    while (value.MoveNext())
    {
        if (value.Current is IEnumerator enumerator)
            await MyTask(enumerator);

        await Task.Delay(20);
    }
}

[timid meteor]

Having some coding issues atm with this code. The Error I am getting is sthis

Trying to make some grass atm

[rigid island]

write the loop so it makes sense

[gray mural]

Are you sure it's C# syntax?

[rigid island]

what is : supposed to do ?

[timid meteor]

Yea I am trying to do gpu instancing for grass

[gray mural]

I guess : is used in a foreach loop for some languages as in in C#

[rigid island]

have you used a List before ?

[timid meteor]

not really in the dark with this mostly

[rigid island]

you need the instance in the list " Batches"

loop over that

[gray mural]

Your list contains items, which are List<Matrix4x4>. You can check that out by using var

So you can just call 2 loops

[leaden solstice]

So just do foreach (var batch in Batches)

[timid meteor]

would that work?

for peformance reasons

[leaden solstice]

Performance for what?

[gray mural]

foreach (List<Matrix4x4> batch in Batches)
{
    foreach (Matrix4x4 matrix in batch)
    {

    }
}

Batches.ForEach(b => b.ForEach(m => 
{

}));

[timid meteor]

I am trying to load a ton of grass in a scene

[leaden solstice]

What does that suppoused to do with syntax error

[rigid island]

maybe start with like pong or something

if you don't know c# syntax

[simple egret]

I think they're mixing it up with languages that put the type after the name in declarations
Like let x: int32 = 45

[rigid island]

go?

[simple egret]

idk, I made that syntax up, but it surely exists somewhere

[rigid island]

oh wait go doesn't use :

var b, c int = 1, 2

Unity Cloud server functions API uses Go

[fervent furnace]

typescript/rust/python iirc

[leaden solstice]

Rust but with i32

[fleet tide]

Hey ! i would like to, create an updater but how can i do that if i want remplace every file even the executor ? (like an self update) In this way, with 1 download, we can have always the latest version

[rigid island]

Make the user direct where the install folder is and replace all the files with the new ones ?

You'd have to handle things like files while in use

[fleet tide]

No, only click on "update" and every files will be update

maybe I was thinking of creating a temporary file to run code

[rigid island]

thought you were making an updater app separately than unity

btw if you use addressables you can just replace specific files instead, no need to update the whole build

[fleet tide]

yeah of course! but if i want update the "game launcher" with updater , i have to as kto everyone to download again the game launcher ?

[rigid island]

no you stream the update to the game launcher

ideally with an API call to your versioning

making a launcher, especially a bad one might deter players so be careful with that

[fleet tide]

So i can create an Game Launcher who can update itself by an API and update the game ?

[rigid island]

yes of course

anything can be coded

[fleet tide]

Interesting ! I wanted create a game launcher but i trought is was better to have it in my game

[rigid island]

if you do it in-game go with the addressables maybe

[fleet tide]

I never use addressables but i will learn 🙂

thanks

[rigid island]

for example
https://docs.unity3d.com/Packages/com.unity.addressables@2.0/manual/builds-update-build.html

you can make a build just containing the updates

https://learn.unity.com/course/get-started-with-addressables

[fleet tide]

Thanks for the link !

[rigid island]

do note in some cases it might be better to just update the whole build

[fleet tide]

for now, its a very light game so its more for later ^^

[lament helm]

has anyone coded an rpg?

pokemon style combat

[pastel patio]

Hi guys, how is input rebinding intended to be used? The rebinding sample changes the binding referenced by an InputActionReference, I don't understand how this works

[gray mural]

https://dontasktoask.com/

[pastel patio]

The input I created elsewhere isn't the one referenced thus leading to the rebinding to apply to an unused instance

Is there a specific instance that the InputActionReference points to that I can find? Was I meant to use that one?

[rigid island]

#🖱️┃input-system

[pastel patio]

Oh... I thought that this one counts as programming related

Sorry

[rigid island]

input system covers both

[lament helm]

can someone who has coded an rpg tell me the logic behind creating a pokemon style battle system in unity 2d

[rigid island]

you want someone to give a whole thesis on how the logic of an rpg works

[pastel patio]

These kinda stuff has too many ways...

[lament helm]

yes

[rigid island]

thats something you can easily google, cause as mentioned above there are dozens of ways to accomplish something

you have an easier time getting help on a specific part of code you're stuck on

[lament helm]

understood

[heady iris]

I am rewriting my "IK Manager" class. It's going to support multiple different IK components, and different kinds of components are identified differently

For example, a generic chain IK is just going to be identified by the last bone in the chain

there's also a full-body biped IK component that controls all of the limbs, and so I identify which limb I'm moving with an enum

so right now I've got this, basically

public void SetTarget(FullBodyBipedEffector effectorID, Transform target)
{
    if (bipedIKControlMap.TryGetValue(effectorID, out var controller))
        controller.SetTarget(target);
}

public void SetTarget(Transform tipBone, Transform target)
{
    if (chainControlMap.TryGetValue(tipBone, out var controller))
        controller.SetTarget(target);
}

This is fine.

However, I'm finding it annoying to allow other components to flexibly use both kinds of IK

I have a component for pulling a lever. For a humanoid, it wants to use a full body biped IK's right hand. For a non-humanoid, it will need to use a different kind of IK to control a robot arm or whatever

I need to be able to configure both kinds of IK interaction on this "pull lever" component

I had the thought to just do this:

[System.Serializable]
public abstract class IKSelector : IPolymorphic
{

}

[System.Serializable]
public class FullBodyBipedEffectorIKSelector : IKSelector
{
    public FullBodyBipedEffector effector;
}

[System.Serializable]
public class TransformIKSelector : IKSelector
{
    public Transform tipBone;
}

and then...

public void SetTarget(IKSelector selector, Transform target)
{
    if (selector is FullBodyBipedEffectorIKSelector fullBodySelector)
        if (bipedIKControlMap.TryGetValue(fullBodySelector.effector, out var controller))
              controller.SetTarget(target);

    if (selector is TransformIKSelector transformSelector)
        if (chainControlMap.TryGetValue(transformSelector.tipBone, out var controller))
              controller.SetTarget(target);
}

and I...guess this works? it just feels kind of weird

this is a lot like making an algebraic datatype in a language like Haskell though

[heady iris]

(IPolymorphic gives me a dropdown selector when used with [SerializeReference])

I still don't know what to do with my code: Whenever I try to rotate my gameObject, it spawns a clone of it. Here's the code: https://pastecode.io/s/09qwryx7 https://pastecode.io/s/z4i3hhyd https://pastecode.io/s/nwottz8w

[rigid island]

we told you what to do. #💻┃code-beginner message
#archived-code-general message

Nuke the code, start over with something that makes sense

don't write redundant WET code

You ended up not understanding your own code, thats how you know is especially bad if you've written it yourself

[lean sail]

You are now seeing the reason its HEAVILY suggested to do basic programming first, and even basic problems, before unity.
This code is complete spaghetti, you are trying to rotate an object and its spawning something? Its pointed out everytime you post code.

I tell so many people this, you'll waste HOURS debugging complete garbage code, compared to just learning how to properly code in those few hours and having something decent

Although really, we also know you havent debugged anything in there, even though it's been suggested before.

The sunk cost grows and grows

[spring creek]

I have completely restarted projects far further along than this multiple times. Or reverted to an earlier state MANY times.
That is part of progress.
Can't be afraid of restarting

[opaque forge]

Hello, I have a problem which I'm trying to solve which I thought I could use Physics.Raycast for, and I don't get why my approach is not working :
I'm generating a bunch of tiles with edges surrounding them, but for some cases it generates incorrect tiles, so I delete them under a certain condition. However I have
the edges surrounding the deleted tiles present in the scene, and I want to delete edges that are not surrounding anything. The solution I thought about is to use Physics.Raycast on both side of each edge to perform a check if it's enclosing a tile (I attach a collider to all tiles). For some reason, as you can see on the picture above, it works in most cases but there are a few edges that are not deleted and I don't understand why, it's seems that the raycast detects something even though nothing is there

[heady iris]

Is that near the origin? I wonder if the physics world is out-of-date when you do the raycast

notably

var tile = Instantiate(myPrefab, Vector3.zero, Quaternion.identity);
tile.transform.position = Vector3.right * 100f;
Physics.Raycast(Vector3.up, Vector3.down, 100); // this hits the tile!

Calling Physics.SyncTransforms(); gets everything up to date

[opaque forge]

I set up automatic physics sync transforms in the settings but I'll check with this again

[opaque forge]

wdym near the origin?

[opaque forge]

didn't work rip

[heady iris]

near [0,0,0]

i forgot about that!

[opaque forge]

I know what it means haha but why are you saying it?

[opaque forge]

omgggg

[heady iris]

Because if you instantiated your hexes and then moved them, they'd all be left at [0,0,0] in the eyes of the physics system

[opaque forge]

wait I'll check the settings

[heady iris]

(or wherever the hexes appeared at)

[opaque forge]

I create the meshes on the locations I get from a voronoi diagram library

the weird part is that some edges do get deleted like they are supposed to so I think it's got smth to do with the physics system

[heady iris]

are you drawing a red ray when it misses?

if so, the raycast is working fine

oh, they're all red

i'm bad with red and green

Try making it draw a different color if the raycast hits

that will reveal if it's a bug with your logic afterwards

[opaque forge]

yeah maybe raycasting is not suitable in my case where everything is done in the start frame

[heady iris]

Consider logging what you're actually hitting

Does anyone here know if Shadergraph Fullscreen shaers work on mobile?

Describe your problem concisely, and link the post

[novel dagger]

https://reddit.com/r/Unity2D/comments/1d5c7x2/help_with_creating_an_elastic_rope_in_my_first/

i think i explained it concisely in the post and i tried to explain what i think is wrong and how i tried to fix it

feel like i’m missing something fundamental

i have a rope linking a player and a collider, the rope should stretch if the player moves away from the max distance but the rope isn’t stretching or growing despite the fact that my debug statements somehow say it’s moving further away (even though it’s physically in the same place)

hey guys would anyone know how to https://pastebin.com/UfmWhxrA

It's some boiler plate code I found that I need a small change too

right now it creates a seperate scene and loads that, but this doesn't work for my use case of multiplayer scene management, so I need someway to just basically import the asset/scene into my current/main scene

[void wedge]

is there just a general help channel? Im trying to fix my slider UI

my health bar slider is starting at the edge but when it reaches value of 1 (full) it sits in the right spot?

[frosty widget]

I have a question for those that are familiar with unity's physics system, particularly with the drag value of RigidBody2D. In my InAirState script, I am capping the horizontal velocity of my character whenever it reaches it's max speed. However, drag is reducing the value that I have set at the end of FixedUpdate, to a value below the max. A solution to this issue would be to set the drag to zero, but this makes my jumps higher than intended. Is there a way to solve this issue without reducing drag? Here is my script and some related ones https://gdl.space/niyeqoyohi.cs, https://gdl.space/kigoxizevi.cs, https://gdl.space/udolejurep.cpp

[mortal pond]

wdym right spot

which one is health the red green or blue

[void wedge]

the red is the health bar, The green and blue bar are sitting in the correct spot (because I havent added slider to them yet). I want the red bar to start and end where the other bars are

[mortal pond]

is this the issue

check for padding settings

[void wedge]

yea its just being pushed back instead of starting where it should. As the value increases the health bar moves into its correct place where the others are

[mortal pond]

did u make a direct copy of the other ones and then move it up and change color

[void wedge]

ive got the fill color set to stretch

I made the health bar first and copied the other 2 from that, but those dont have sliders on them yet

When its on max value its in the correct spot but idk why its out of position when it starts

[versed marsh]

how do you create these types of UI elements again? If I'm remembering correctly there is a class that allows you to create very simple UI like this in code, but Im forgetting what its called and cant find it online.

[spring creek]

There is UGui, and UIToolkit. You can do both in code really, but UIToolkit uses language like html and css (uxml and uss).

That being said, I would not call that a simple ui. Lots of logic involved in that, rather than just showing values

[rigid island]

this is the older gui
https://docs.unity3d.com/ScriptReference/GUI.Button.html

Ideally you should use the Canvas / UI Toolkit

these are only okay for testing

[versed marsh]

ahh okay, didnt realize it was depricated. The only reason Im trying to use it is since Im making a mod for another game and just needed a very simple ui button

[frosty widget]

Does anyone know an equation to handle drag in the same way that unity does?

I googled it and tried out RB.velocity **= 1/(1 + Time.fixedDeltaTime * * dragValue ), but this formula didn't work

didnt work in what way? also where did you find this formula, it doesnt really look right and is different from what i see online

look at the #854851968446365696 on what you should include in questions. We'd need to see more of the setup like code, how you pick up items or drop them. I assume you duplicate the item

!code the readme also says the same for large code blocks. Though really, you should narrow it down to a related sections. posting it all in a link is fine, if you at least say where to look and whats relevant. not many people are gonna read through that much code

Hey guys,
I'm implementing fishing system. I have characters animations for fishing and rod animations separately.
Does it make sense to use separate animators on each with same states and transitions and just set triggers or bools for transiting between them ? Will they be in synced ? (Animations length are same in both the rod and the character for the each kind of animation)

[rain junco]

https://paste.ofcode.org/34RZXLaS2mZyBG7tjsP5LtK i have this script and in GetPickaxeSprite it tells me item is null. I assigned the iconList in the Inspector

[knotty sun]

post the actual error, screenshot the console

[rain junco]

i logged the name before in the foreach loop

it tells me the second element then this

[knotty sun]

The error does not match your code but assiming line 103 is line 102 it means item is null so you have a null item in your array

[rain junco]

but idk why

[rain junco]

its from before i had a extra line to log it

[knotty sun]

that is why we debug. Add a null check

[cosmic rain]

Might also want to print the name of the object that the code runs on

[solid rivet]

hello guys. I have a problem. I have a unity project and i dont konw how to setup a click event, because the design has changed from unity itself. I have 2 images and i want to have it like the old design (marked with red). Someone can help me with it?

[rain junco]

why that

[cosmic rain]

Because you might have this script running on some other object that has a null reference in the array

[rain junco]

true

doing now

foreach (var item in iconList)
{
if (item == null) Debug.Log("An item is null" + gameObject.name);
}

no other object

is there a problem with an in inspector assigned list?

[cosmic rain]

Then the item is null

[knotty sun]

try logging the index of the item

[cosmic rain]

Not necessarily. It could be null temporarily for example.
Ideally you want to step through with a debugger

[rain junco]

i just noticed they got reset when starting, didnt happen before

[cosmic rain]

Do you have the inspector in debug mode perhaps?

[knotty sun]

your code does have this in Start.
iconList = new PickaxeIcon[iconList.Length];
that's why

[rain junco]

worked, i made a thinking mistake

[rain junco]

ye

that was it

[solid rivet]

how can i check this?

[solid rivet]

no i had it in debug mode hahah

i love you so much bro thanks a lot

[dusky niche]

sword.transform.parent = transform.GetChild();
if the child is also a parent then would it work if I put the total index number of the child inside the transform?

[knotty sun]

what are you trying to do, because that is invalid code

[dusky niche]

trying to make an object as child of another object

[knotty sun]

I know that, but which child should become the parent?

[dusky niche]

sword is an inherited gameobject
Trying to become the child of the object this script is attached in

[knotty sun]

then why GetChild ? just use transform

[dusky niche]

child in the transform

[knotty sun]

i think you are misunderstanding

sword.transform.parent = transform; // set sword as child of transform
sword.transform.parent = transform.GetChild(0); // set sword as child of child zero of transform. (Grandchild of transform)

[dusky niche]

I mean make the child inside the child as parent

[knotty sun]

what?

[dusky niche]

Let's say the script is on forearm.R
I want the sword as child of the index1.R

[knotty sun]

presuming you just forgot to mention the 001 bit of the names

sword.transform.parent = transform.GetChild(0).GetChild(0);

[dusky niche]

I see thx

[knotty sun]

you do realize this will go bang if those children don't exist or are organized differently

[heady iris]

it would be significantly better to store a reference to the transform you're attaching the sword to

rather than rooting around in the hierarchy like you're mining for coal

[hard tapir]

which script is more performant? ```
using UnityEngine;

public class Script1 : MonoBehaviour
{
private Manager manager => GetComponent<Manager>();

private void Update()
{
    if(manager.b != null)
    {
        mananager.b.Func();
    }
}

}

using UnityEngine;

public class Script2 : MonoBehaviour
{
private Manager manager => GetComponent<Manager>();
private B b;
private void Awake()
{
b = manager.Resolve<B>();
}
private void Update()
{
if(b != null)
{
b.Func();
}
}
}

using UnityEngine;

public class Manager: MonoBehaviour
{
public B b;
}```

[cosmic rain]

The second one, since the first one calls GetComponent every frame. But the difference is probably not very noticible.

[gray mural]

Hello, just to make sure. These 2 variants do have 1 frame difference in in time, right?

WaitForSeconds(2f);

WaitForSeconds(1f);
WaitForSeconds(1f);

So Unity doesn't call the 2nd IEnumerator in the same frame when the 1st's MoveNext returns false, it waits a frame instead?

[leaden ice]

They will have a difference yes

more than one frame

[gray mural]

In the 2nd variant, you get the Component only once, in Awake. In the 1st variant, the Component is gotten every time you access the getter of the property, in your case, every Update, which acts the same way as the method. So the 1st variant is much worse

[leaden ice]

WaitForSeconds waits until the next frame after N seconds have passed

[gray mural]

Why would the difference be more than 1 frame though?

[leaden ice]

So you'll get like:
2.01 seconds (assuming frame error of .01 second)
vs
1.01 + 1.01 seconds

well one thing also is that frames are not consistent durations

[gray mural]

I see, I wasn't assuming the errors

[leaden ice]

so if the frame error for the first wait is longer than a later frame, it could be 2 or more frames

[gray mural]

The 2nd variant should get 1.01 + 0.01 + 1.01 this way though

[leaden ice]

It just depends on the luck of where the frames land basically

[hard tapir]

Are you sure about that?

[gray mural]

Yes

[hard tapir]

because script 2 gets B just once right?

[gray mural]

I see, so it doesn't move to the next IEnumerator in the same frame. Thank you

[hard tapir]

in script 1 it gets that B through manager but every frame

[gray mural]

Yeah, I'm sorry, I have confused 1st and 2nd script. You can reread my message and replace every 1 by 2, and 2 by 1

[leaden ice]

note that these aren't necessarily functionally equivalent. If manager.b ever changes after Awake, the second script will not pick up that change.

[hard tapir]

B is always the same

[gray mural]

Yes

[hard tapir]

so conclusion is that script 2 is better? => storing local variable and then get it once is better

[gray mural]

But regardles of B staying the same or not, b stays the same

[gray mural]

If we're talking about the performance, yes, it is

[hard tapir]

okay, thanks!

[gray mural]

Just make sure that b is changed when the different value for manager.Resolve<B> can be gotten

And it would be better to simply remove the property

As I don't see whether you need it

[cosmic rain]

I'd disagree about the "much worse". It is worse, but the impact this one difference would have is probably barely noticeable if at all.
Not saying that you should use the first variant. You should definitely cache your references whenever possible. But it's important to understand that it's not gonna explode your game.

[spring creek]

I would move away from using OnCollisionEnter and OnCollisionExit for ground checking. What if your head hits the ceiling..

Oh, and its gone

[leaden ice]

If you hit your head, the player will forgive the character for mistakenly thinking it is on the ground, since the character likely has a concussion.

[maiden heath]

i put the collisonenter and collisionexit in another gameobject called groundcheck and its a small box collider on the players feet

that should solve it

[maiden heath]

😂

[spring creek]

Ah gotcha. So the code you showed is two scripts?

[maiden heath]

https://pastebin.com/f8DLrzKM this is the groundcheck script
https://pastebin.com/g4PgLBKJ this is the player script

[gray mural]

Yeah, just consider applying the changes I've told you about

[spring creek]

Yeah, that works then, and avoids the issue I mentioned

[maiden heath]

i did

[gray mural]

I cannot see it on the scripts you've sent though

[maiden heath]

oh i didnt update them yet

will do in a sec

[cosmic rain]

Unless you jump high enough to clip through the ceiling and getting stuck in it, since it will be considered grounded

[maiden heath]

i updated it now

[glacial tundra]

Just wanted to report back and say Playables are definitely the way to go for simple sprite animations, if you want to handle them in code. I was able to implement it yesterday and it seems to work well. There is a gotcha associated with setting time on AnimationClipPlayable objects, but that was the only real issue encountered.

[gray mural]

I would have a reference to your feet in the PlayerMovement script, and add the GroundCheck script to it in Awake.

private void Awake()
{
    GroundCheck groundCheck = feet.AddComponent<GroundCheck>();
    groundCheck.playerMovement = this;
}

Then assign its playerMovement reference and access isGrounded and groundLayer from it.

private void OnCollisionEnter2D(Collision2D collision) => SetGrounded(collision, true);

private void OnCollisionExit2D(Collision2D collision) => SetGrounded(collision, false);
 
private void SetGrounded(Collision2D collision, bool value)
{
    if (collision.layer == playerMovement.groundLayer)
        playerMovement.isGrounded = value;
}

[hard tapir]

Of course but every bit counts

[maiden heath]

what difference will this make?

[sleek heath]

erm. I'm pretty sure MoveTowards exists

[gray mural]

Of course, it's going to "exlode" your game if done with every variable possible

[cosmic rain]

Not when you have bigger problems in the project.
If your intention is to optimize the game, you should start from profiling it. Not changing random code.

[hard tapir]

Also this is for readability

Because more and more code there is the more confusing it gets

Hey everyone! Trying to be able to get a variable FROM a class by name rather than hardcoding shit and it be a pain (so, like if i called GetVariableByName(keyName, className), the class i'm trying to find is what 'className' is, and the variable i'm tryna find is what 'keyName' is.)

Alright so here's the whole script: https://hastebin.com/share/ubexozaqob.csharp

But any time i call GetVariableByName() it comes back as null - i would search as to why but to be honest I have no idea what I'm doing or why i wrote what i wrote. I'd love to know how or why what i did is not doing what its meant to did
if you need more info do let me know

[cosmic rain]

What debugging steps did you take so far?

I'm not going to say that if you're gonna use that widely in your project as a replacement to normal accessing methods, it's gonna be terrible. I assume you know it and have a specific use case.

[eager steppe]

• checked that the lists we're accessing are not null
• checked that all properties inside said lists 100% exist
• Checking what keyName and className we're passing, they're correct

[gray mural]

Is this the only thing bothering you in the method I've provided?

[cosmic rain]

So does it enter any of the if statements here?

    if (property != null)
    {
        object value = property.GetValue(root, null);
        if (value != null)
        {

[eager steppe]

It's just for one feature - skinning (so altering the color/sprite/whatever of gameobjects). All gameobjects have an ApplyColor.cs if they need to be changed. They have a keyName and className to fetch which i give to them manually through the inspector.

[eager steppe]

enters the first property check

[gray mural]

This prevents from from the requirement to add the GroundCheck script manually

[maiden heath]

ah ic ic, thanks for the headsup

[simple egret]

None of the classes posted here actually have properties in them, they're all fields. So GetProperty() won't be finding anything. For reference, a property declares accessors:

public int SampleProperty { get; set; }

What you have don't have accessors, so they're all fields

[eager steppe]

OHHHHH
okayy, i'll do that then -- thankss SPR

[dusk brook]

Which UnityEngine class would a Panel come under?

Just GameObject?

[cosmic rain]

It's not a one specific class. It's a gameobject with some components(I think a UI image) and some default settings.

[dusk brook]

So how would I reference it?

And GameObject doesn't even work

[cosmic rain]

Depends on what exactly in it you want to reference.

[dusk brook]

Simply the size of it is all I want

Dynamically

[heady iris]

you can reference its RectTransform.

[cosmic rain]

Not sure what you mean by size of it, but GameObject should work as a reference

[dusk brook]

When I can figure out how to get it I can try and get its RectTransform

[cosmic rain]

What exactly are you doing?

Is that a serialized field?

[dusk brook]

Yes

[cosmic rain]

What type does it have?

[dusk brook]

GameObject

[cosmic rain]

Share the code

[dusk brook]

Attempting to select the panel

[dusk brook]

public GameObject simulationVisualCanvas;

It's in a ScriptableObject

[cosmic rain]

You can't reference scene objects from outside the scene.

[dusk brook]

Sounds logical yup

Thanks

[dusk brook]

Ultimately the problem I'm trying to solve is I want a box for the simulation (ie the green area) which can be dynamicly sized and accessed from the code - How is this typically done?

[cosmic rain]

Referenced somewhere in the scene.

Your code should be in the scene as well

Can't say anything else without knowing the context

[dusk brook]

My simulation code is in the scene, as a script, I'm just wondering what kind of box/container is used to manage components that can be resized

[rigid island]

is it UI or non-ui ?

[limpid agate]

Hey guys, any idea why in the game view (using the camera), the line renderer doesn t render some parts of it, while in the scene, it s perfectly fine?

[dusk brook]

Is what ui?

[cosmic rain]

Well "components that can be resized" is a very vague definition. What component exactly? Are they ui Image components?

[rigid island]

not a code question #💻┃unity-talk

[dusk brook]

Bear with me, I'm trying to comprehend this myself

Here I have a panel (green) representing the simulation field - I want to be able to get the size of this panel, and to be able to resize this panel as well

The panel contains 2d game object organisms

[cosmic rain]

Maybe start simpler and go through unity !learn beginner pathways. It's gonna be very hard to help you if you don't understand the basic terminology

[tawny elk]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[cosmic rain]

Also, you might not need help at all if you do proper learning. Killing 2 stones with one bird

[dusk brook]

The problem is I'm doing this for a dissertation and to be honest its not about how it looks per se, I'm focusing on the neural network side for the entire project, but trying to get it all visually is taking bloody ages because of this steep learning curve

The dissertation is like 90% theory and neural network but ultimately I'm spending all my time trying to build a graphic for it

[cosmic rain]

It's not really steep. You just need to spend a day or two on learning the basics of working with the engine(assuming programming is not an issue).

You can't jump into a professional software and hope to get something working of it by randomly pushing buttons. That's not how it works.

[gray mural]

Does Unity still wait for 1 frame after moving through all IEnumerators in a Coroutine when no MoveNext is available?

WaitForSecond(1f);
WaitForSeconds(1f);
// 1 frame
// stop

[knotty sun]

which, tbh, if you are doing anything with Neural Nets, you should already know

[rigid island]

why not test it

[dusk brook]

Okay, I'll do some learning into unity

[heady iris]

if you yield return new WaitForSeconds(1f);, Unity will wait for 1 second before calling MoveNext again.

At that point MoveNext will return false

I'm not really clear what you're asking about here, though

[gray mural]

How would I test it?

[dusk brook]

I suppose, but my use for unity is pretty simply - Literally a couple entities moving about a screen, not much more

[gray mural]

It calls MoveNext every frame, not every second

[heady iris]

show me the code you're actually running

[heady iris]

this code does not make any sense to me

[gray mural]

It checks whether WaitForSeconds has finished executing by calling its bool MoveNext every frame

[rigid island]

maybe try counting the frames between?

[knotty sun]

Neural Nets are serious tech. So I would assume a very good knowledge of 'not so serious tech' to back that up with

[rigid island]

but yeah unclear what you're even going for here or what problem you're experiencing

[cosmic rain]

If your intention is for it to continue exactly after 1 sec then that's unlikely to happen.

[gray mural]

Well, of course

Unity is not precise

[dusk brook]

Not sure what you're getting at here

[gray mural]

That's why WaitForSeconds doesn't work in Editor, which just calls Update when any change was done

No MoveNext is called in this case when you're doing nothing in Editor

[heady iris]

i still don't understand what your problem is or what you're asking about

[cosmic rain]

There are editor coroutines package btw. For editor coroutines

[knotty sun]

what I'm getting at is not knowing common terms like Ui and UX and not realizing you need to learn software before trying to use it

[cosmic rain]

You don't really need to get into the guts of the coroutines. All you need to know is that it would resume on the first frame when the condition is satisfied

[gray mural]

Unity waits for a frame after getting false from an IEnumerator's MoveNext, then moves on to the next one. I wanted to make sure whether it still waits for a frame when no next IEnumerator available

[simple egret]

If MoveNext was called every frame, it would resume the coroutine and run it to the next available yield each frame. It waits until the second has passed before calling MoveNext again

[gray mural]

And I have mentioned why its WaitForSeconds doesn't work properly in the previous message

[rigid island]

https://docs.unity3d.com/Manual/ExecutionOrder.html
might help you as well, shows all the yields

[candid elm]

is it coding, sons

[heady iris]

Are you talking about this kind of situation?

public IEnumerator CoroutineMethod() {
  Debug.Log(Time.frameCount);
  yield return AnotherMethod();
  Debug.Log(Time.frameCount);
  yield return AnotherMethod();
  Debug.Log(Time.frameCount);
}

public IEnumerator AnotherMethod() {
  yield return null;
  yield return null;
}

[dusk brook]

Is this for me specifically?

[rigid island]

yield The coroutine will continue after all Update functions have been called on the next frame.
yield WaitForSeconds Continue after a specified time delay, after all Update functions have been called for the frame

etc.

[knotty sun]

no, not at all, just a general observation

[rigid island]

so apparently all yeilds wait for the Update to finish

[dusk brook]

Ok, ok, I get you, yes a classic thing is people seeing something cool and wanting to be able to create it from scratch themselves without having sufficient prior knowledge

[gray mural]

There is a class CustomYieldInstruction with an abstract bool keepWaiting, which, according to its documentation

is queried each frame after MonoBehaviour.Update and before MonoBehaviour.LateUpdate
This class also has a method MoveNext, which references the boolean

public bool MoveNext() => keepWaiting;

[rigid island]

you can see where the yield run

[simple egret]

Yep that's the custom one

Regular ones are polled less frequently

[rancid frost]

mesh renderer sorting layer not working?

White square sprite and green square mesh are on thesame sorting layer but different order, but still they intersect. Why?

[rigid island]

Z fighting

[gray mural]

Yes, probably

[simple egret]

Because IEnumerators are really compiled into a big state machine class that really advances the state to the next yield when you call MoveNext on it

[rancid frost]

please do elaborate

[heady iris]

The example with MoveNext is not a custom yield instruction.

[rigid island]

actually , is the big white squae a mesh and the tilemap sprites?
also this isn't code related

[cosmic rain]

Sorting layers only work with orthographic cameras and geometry oriented orthogonally towards the camera afaik.

[rancid frost]

white square is a sprite, its not a tilemap, although similar, it is my own custom tilemap made of meshes

[rigid island]

yeah not sure layer order would affect the scene view

[heady iris]

Ah, you were looking inside CustomYieldInstruction. I see now.

[gray mural]

So you're saying it doesn't start a timer in its constructor and simply check for the timer being completed in its bool MoveNext?

[rigid island]

try shifting whatever you want slightly forward on Z

[rancid frost]

camera is currently ortho.

[rigid island]

ohh its meshes?

then Order In Layer will not affect it

Mesh Renderer doesn't care about that only sprite renderer

[gray mural]

YieldInstruction is decompiled, so, I suppose it still does the same?

[simple egret]

It runs MoveNext() to see if there's any code left to run in the enumerator. Then it accesses current to see what was yielded by the enumerator

[rancid frost]

I see

[heady iris]

When you yield an IEnumerator from a coroutine method, Unity will start polling its MoveNext() method until it returns false. Once it does, it goes back to the original enumerator.

[rancid frost]

just noticed, in game view its a bit different, but still cant affect the ordering

[rigid island]

Yes that is what @cosmic rain mentioned, it would only work on Game Cam

[cosmic rain]

You can make the scene cam orthographic too

[rancid frost]

So is there nothing I can do to order the meshes?

I want to have multiple meshes ontop one another

[rigid island]

are they sprite renderer or mesh render ? im confused

[rancid frost]

the white square is sprite renderer, the green mesh is mesh renderer

[rigid island]

ohh

cause its trickier to sort 3D materials

[cosmic rain]

You should just position one in front of the other.

[rigid island]

i believe thereis a render order on the shader though

[rancid frost]

so best bet is just to modify the transform?

[rigid island]

yes

use the Z position to sort

[rancid frost]

will culling still take place?

[heady iris]

culling is frustrum-based (i.e. based on what's on the screen)

well, there is also occlusion-culling

[rancid frost]

so it would

[heady iris]

but that is baked in advance for static geometry

[gray mural]

I see, so it stops right after the IEnumerator is finished and doesn't wait for 1 more frame. This clears the things up for me, thank you

[heady iris]

Right. I wondered if using something like this would cause a delay, but I haven't managed to cause one yet:

    public IEnumerator CoroutineMethod()
    {
        Debug.Log(Time.frameCount);
        yield return StartCoroutine(AnotherMethod());
        Debug.Log(Time.frameCount);
        yield return StartCoroutine(AnotherMethod());
        Debug.Log(Time.frameCount);
    }

    public IEnumerator AnotherMethod()
    {
        yield return null;
        yield return null;
    }

Ah, it makes sense because Unity is not doing this:

• check if CoroutineMethod can resume
• advance AnotherMethod

It's just advancing AnotherMethod, and the moment it's done, it advances CoroutineMethod

[gray mural]

Do Unity's Coroutines use async?

[rancid frost]

when sorting via z positioning (in my case Y), it there a good number to layer above? or should I find the smallest number possible?

[heady iris]

No, they don't use async at all

There is Awaitable (2023.2+), which lets you handle async methods more like coroutine methods

I'm still a bit unclear on the technical details of async.

[gray mural]

Is it's 2023.2+, then Unity's Coroutines surely don't use it

[rigid island]

yeah they dont need to be that far apart IMO

depends what you're going for, the smallest number could potentially be all you need anyway

[rancid frost]

roger, thanks!

[cosmic rain]

Just note that some platforms might behave differently and need a bigger distance.

Otherwise there might be z fighting.

[heady iris]

The closer your near and far clip planes are, the closer you can place objects without getting z-fighting

(of course, that means you have less space to place your objects!)

you can't cheat the system (:

[tawdry fox]

My brain can't syntax right now but I feel like this is where I'd put a check for a coyote timer right??

Feels like it should be obvious but I've been using Godot for the better part of a year and kinda forgot.

[vivid halo]

If the player becomes ungrounded and makes a jump, you can check the coyote timer to see if you can give the player a free jump

I know you didn't ask, but two points of advice:

• Curly braces should generally be on the same line for readability

{
  // Code
}

• Enumerations should be used for integers that represent stages, such as jumpPhase = 0. Instead, it could read if (jumpPhase == JumpPhase.PreJump) or if (jumpPhase == Jumpphase.MidAir

[leaden ice]

Enumerations* aka enums

[vivid halo]

Oops yeah, correcting

[leaden solstice]

I think jumpPhase is counter here

How many mid-air jumps you performed

[lean sail]

Theres no readability aspect to this, it's just convention. C# convention has it on the next line, and this is by default in VS. Other languages do it on the same line, it's the default in VSCode.

[vivid halo]

It's absolutely readability, but it's also convention.

[lean sail]

Nope, 0 readability aspect to it. It's simply more or less readable because you are used to it. I find same line completely unreadable these days, because I do next line. In uni I used languages which did it on the same line, at the time I thought it was readable

[vivid halo]

In University I used

public void Example() {
  // Code here
}

And I was used to it, but it is simply less readable than matching braces.

[leaden solstice]

Readability as in consistency 😄

[vivid halo]

Matching blocks of code requires scanning side to side instead of simply following the vertical space down. Largely preference, but readability is a non-zero factor.

[lean sail]

Unless you do a case study where you ask random people which is more understandable, theres no debate about it. It's simply just what you're used to, because it's where you subconsciously expect it to be

[tawdry fox]

Anyways I appreciate the input.

[leaden solstice]

Almost all C# libs uses Allman style so you might as well too
If you are writing in Rust or Java that's different story

[vivid halo]

I was used to K&R first, and forced to adapt to Allman style, allman is more readable. Seems nonsensical to argue that K&R is more readable

public class ExampleClass {
  public void ExampleMethod() {
    if (condition1) {
      for (int i = 0; i < 10; i++) {
        while (condition2) {
          if (condition3) {
            DoSomething();
          } else {
            DoSomethingElse();
          }
        }
      }
    } else {
      AnotherMethod();
    }
  }

[leaden solstice]

That is unreadable, no matter what indentation style you use 😄

[vivid halo]

Is a poll required?

It's complex and not readable by baseline, but using Allman is very clearly a better choice for something like that.

[lean sail]

No, and I'm not claiming either is more readable. That is your claim. I am saying it's your preference, and generally you shouldnt enforce code style here. Conventions differ, as long as it is consistent for a project that is good.

[vivid halo]

C# and Unity's official documentation prefer a certain style. The style wasn't chosen by dice roll.

[heady iris]

why not push all of the braces to the right side of your screen so you can pretend you're writing Python

    public void OhNo()                                              {
        if (true)                                                   {
            Debug.Log("Wow!");
            Debug.Log("This is great!");                            }}

[vivid halo]

Yeah guys, it's just preference

[tawdry fox]

I use jumpPhase as jumpCount exclusively because that’s what the person who gave me the example used lol. Definitely a bit confusing though.

[leaden solstice]

Yeah Python played smart and eliminated the possible arguments like this

[vivid halo]

Python introduced whitespace-dependent code which is terse but introduces its own issues.

[heady iris]

and, in its place, it introduced about a trillion arguments about what is "pythonic"

[knotty sun]

Python introduced? It's been around for more than 40 years in a few languages you have never heard of
