[wintry crescent]

but this - can I get rid of this boilerplate

in ANY way

IProcedure derives from IListenable and ProcedurePointsblabla derives from IProcedure

[heady iris]

I think the most reasonable option here is to just store a Delegate. You can cast these back into the correct type when they're used.

[wintry crescent]

this assumes I give up and my AddListener looks like this

[wintry crescent]

I tried just now, and invoking them is a pain due to them having different amount of arguments

[heady iris]

That will still be necessary.

https://paste.myst.rs/8yu6j0r9

you might find this to be useful; it's a memoizer I use to make exactly one copy of an object for a given set of arguments

I got around the variable-argument problem by just using value tuples

[wintry crescent]

okay I can try with the Delegates again...

[heady iris]

(they aren't mandatory, but the type names hint at what I intend the user to do)

((the user being me))

I find this to be pretty tolerable. Let me find an example of using it

return Memoizer.Memoize(
                (data, entity, state, target, moduleTarget),
                static t => new ModuleTargetedStateActivity(t.data, t.entity, t.state, t.target, t.moduleTarget));

Mildly silly

C# does not support variadic generic types, so you run into a wall there

I feel like I could codegen this

[wintry crescent]

oh god I think I'm too tired to get this. It's almost 1am here...

[heady iris]

I rephrase any constructor as a one-argument function that takes a value tuple

[wintry crescent]

not a clue what this does I think I'll try with those delegates and worst case scenario I'll have the Action<IListenable> and have a bit of boilerplate

[steady bobcat]

I once did an event dispatcher for tfs2 in sbox. This had a class for each event with its "args" defined in there: e.g.

public class PlayerSpawnEvent : DispatchableEventBase
{
    public IClient Client { get; set; }
    public TFTeam Team { get; set; }
    public PlayerClass Class { get; set; }
}

You subscribed with: public static void Subscribe<T>(Action<T> callback, object sourceTarget = null, bool once = false) where T : DispatchableEventBase

This worked decently as on subscription we did this:

//A lambda needs to wrap the provided callback so we can cast the argument and successfully add the subscription.
EventDelegate eventDelegate = ( args ) => callback( (T)args );

//Make event subscription struct to store the casted delegate call, the original and the target entity.
EventSubscription subscription = new( eventDelegate, callback, sourceTarget );

EventSubscription was then stored to invoke later.

[wintry crescent]

if it's this easy I'll be annoyed

[heady iris]

Wrapping the function is an option

This does allocate every time you do it, though

[wintry crescent]

I cannot possibly explain how much that isn't a concern in comparison to all other options XD

god is it really that easy?

[heady iris]

Actually, I'm pretty sure you can avoid an allocation

[wintry crescent]

goddamnit

[steady bobcat]

Hey its what i came to like 2 years ago 😆

[heady iris]

This anonymous function doesn't capture anything

[wintry crescent]

would turning it to a local function avoid allocation?

because rider is suggesting that

[heady iris]

What happens if you add static before (listenable)?

oh, duh, it's capturing listener there

[heady iris]

You'd have to resolve it into an object to put it in a list, and that would allocate

this is a very useful rider extension

[wintry crescent]

whatever, I'm not doing this often, I can have a small alocation there

[heady iris]

yeah

[steady bobcat]

i dont see the concern unless subscriptions/unsubs are done frequently

[heady iris]

this seems sufficient to me though

private Dictionary<Type, List<Delegate>> map;

public void AddListener<T>(Action<T> action)
{
    Type type = typeof(T);
    if (!map.TryGetValue(type, out var list))
    {
        list = new();
        map[type] = list;
    }

    list.Add(action);
}

public void ExecuteListener<T>(T arg)
{
    Type type = typeof(T);
    if (!map.TryGetValue(type, out var list))
        return;

    foreach (var action in list)
    {
        var cast = (Action<T>)action;
        cast(arg);
    }
}

[steady bobcat]

pretty decent tbh

[heady iris]

you're tap-dancing around the type system here with that MASSIVE downcast

but, whatever

you ensure that each list only contains things of the appropriate type

my memoizer does roughly the same thing

[steady bobcat]

add some unsafe ✨

[heady iris]

using a pointer as a joke

[heady iris]

This still can't abstract away the difference between a zero-argument function and a one-argument function

But you could take it a step further

You could accept a Delegate and then use reflection to pull out the parameter types

and then..idk, put them into a System.Tuple and make your map a Dictionary<object, List<Delegate>>?

You'd still need one method for each number of arguments when invoking a method, unless you want to do lots of reflection

I'd just duplicate some code so that I don't want to throw up every time I look at it 😉

it'd be very tidy from the outside

oh god, i just thought about using currying

[wintry crescent]

my silly cast with an allocation is so much simpler, I think I'll just stick with it lmao

[heady iris]

I would do this

just add an extra list for zero-argument actions and add separate AddListener and ExecuteListener methods to go along with it

[livid olive]

Hey all. A bit of a crazy question because I feel a little dumb not knowing the best way to do this. I'm trying to paint a graphic in a [7,14] Grid. I need to find the closest point to my mouse. What would be the best approach in order to find the closest point to my mouse without iterating through THE ENTIRE grid of points?

I was thinking of something similar to a binary search where I just splice the grid in two using two extreame points. Find the closest and drop the other half.

But would this be the best approach?

[modern atlas]

I think the best way is to use a 7x14 grid of small buttons and map each area of a button onto a texture

[livid olive]

lmao ofc!

[steady bobcat]

or use the IPointerClick event

But if this grid has uniform sized cells and you know its position + size then you can easily figure out the cell a position falls in.

[livid olive]

However this graphic must also be painted if the mouse is outside the grid

Closest to

[steady bobcat]

you can still "clamp the pos inside the grid"

[heady iris]

use Plane.Raycast to pick a point on a 2D plane, followed by Grid.WorldToCell

Plane is constructed from a point and a normal vector

[livid olive]

I did not know about the Grid.WorldToCell method. Thanks!

[heady iris]

it's slightly tricky to spot in the docs

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/GridLayout.WorldToCell.html

it actually comes from GridLayout, the abstract base class of Grid

[livid olive]

Oh lol. None the less thank you!

[heady iris]

for Plane, the position will just be the position of the object the Grid is on

and the normal should be its forward vector

var plane = new Plane(grid.transform.position, grid.transform.forward);

[livid olive]

Is forward just an identity vector? 1,1 on the grid space?

[heady iris]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Plane.Raycast.html

you can use this to shoot a ray from the camera onto a plane

you need to figure out where in the world that ray intersects your grid

[heady iris]

so, no -- this is the direction the blue arrow points in when you selected the grid's game object

[livid olive]

Oh Its normal vector.

Or its like point away kinda vector. God my linear algebra is so rusty

[heady iris]

A normal vector points out of a surface

[livid olive]

Also since this game is 2D I kinda just used Input.mousePosition and used cam.ScreenToWorldPoint to get mouse position.

[steady bobcat]

if its all 2d you dont need a plane then, just figure out the world pos inside the grid

[livid olive]

yep. So grid.WorldToCell is all I needed

Just clamp the X and Y within the size of the grid and bam. I got what I needed.

[prime lintel]

Any idea why this breaks?

[leaden solstice]

Do you not see the space at the end

[deep stirrup]

I am making my own renderer for sprites in 3d environment, and I want it to have Screen Space Occlusion like Lens Flare (SRP) have, how can I do it if I can?

[latent latch]

How does SSO even work for something like a single quad? Also not the channel for this type of question. Try asking in #archived-shaders if you're interested in making your own spriterender shader.

[covert dust]

Quick question - what's wrong with my bit comparison?

TargetLayers.value & (1 << other.gameObject.layer)

it's giving me the "cannot implicitly convert int to bool" treatment

TargetLayers is a layer mask

[late lion]

What you've posted is fine, the issue is where you're assigning this. This expression creates an integer, but you are trying to use it like a boolean.

[covert dust]

https://cdn.discordapp.com/attachments/1171988135471755274/1173825535474929674/869641195914141698-1.gif

actually yeah 😅

thanks

it was put raw in an if statement

guess I kinda expected it to auto-interpret 0 as false and 1 as true

[late lion]

That's the case in C/C++ and other languages, but not the case in C#.

[covert dust]

💀

Microsoft was a mistake

[deep stirrup]

oh, I thought is is done via something like a class or function in mono behaviour, sorry

[cedar verge]

Here is my hierarchy. How can I change the panel? Currently they are spaced so the first is x -960, the 2nd -480, 3rd 0, 4th 480 and the last 960. The width is 480. So I wanted to change the x position to change the panel, but I'd like to keep my Horizontal Scrollbar and other elements afterwards. My goal is to make a ClashRoyale-style menu. So when you slide left, it changes the menu.

[wheat cargo]

It's difficult to understand what you mean here, a screenshot of the actual UI would help.

Also #📲┃ui-ux

[cedar verge]

So I'd like to be able to rotate between these menus, but I don't know how to change the menu displayed - 3 is the default. And for the channel, it's the script I don't know how to do, just the x position change. Should I go to #📲┃ui-ux anyway?

[wheat cargo]

You would just need to modify the x component of the anchoredPosition or position on the RectTransform

[cedar verge]

Like that ?

public RectTransform contentPanel;
contentPanel.anchoredPosition = new Vector2(-480, 0);

If yes, it doesn't matter, the code is executed correctly.

[wheat cargo]

What do you mean by "executed correctly", so is it working?

[cedar verge]

The code reaches this point (conditions)

And Debug is sent

[wheat cargo]

You essentially need to modify the x value in the direction of desired translation (this isn't a rotation btw)

so if the width of the cards are 480 something like this:

contentPanel.anchoredPosition -= new Vector2(480, 0);

the other direction would be +=

[cedar verge]

Yes, I tried, but it doesn't change anything.

[wheat cargo]

Show your entire code

[cedar verge]

    public class SnapToPage : MonoBehaviour, IBeginDragHandler, IEndDragHandler
    {
        private const int MinScrollDist = 1000;
    
        public RectTransform contentPanel;
    
        private Vector2 _startDragPos;
        private readonly List<float> _pagePositions = new List<float> {
            -960,
            -480,
            0,
            480,
            960
        };
        private int _currentPage = 2;
        private bool _isDragging;

        public void OnBeginDrag(PointerEventData eventData)
        {
            _startDragPos = eventData.pressPosition;
        }

        public void OnEndDrag(PointerEventData eventData)
        {
            Vector2 endDragPos = eventData.position;
            float scrollDistance = endDragPos.x - _startDragPos.x;

            if (scrollDistance != 0 && Mathf.Abs(scrollDistance) >= MinScrollDist) {
                int direction = scrollDistance > 0 ? -1 : 1;
                int oldPage = _currentPage;
                int newPage = oldPage + direction;
                _currentPage = newPage;
                float newX = _pagePositions[oldPage] + direction * Screen.width;

                contentPanel.anchoredPosition = new Vector2(newX, 0);
            }
        }
    }

[wheat cargo]

What is this component on? the cards or the content panel?

Also are you using a scrollview?

[cedar verge]

On a scrollview

[wheat cargo]

The ScrollView should just handle the dragging for you, so you shouldn't need any of that code

[cedar verge]

Yes, because if the player scrolls 240, he'll get half of 2 different menus.

And it'll never be well centered

[wheat cargo]

Okay I see

All you really need to do is in OnEndDrag is figure out which card is closest to the center and snap to that. I don't believe you need to track mouse position or drag delta at all

@cedar verge Also I don't think your approach is going to work because the ScrollView has full control of the content panel's position, you essentially need to create your own ScrollView component that does what you want

You could instead also try and set the scrollbar's position to where it needs to be so that the card is centered, but you'll need to calculate the normalized scroll position for that

[fiery saddle]

I have this code which loads addressables. And it works fine until the address is wrong. I want to handle those errors and still continue running the game even if the address is wrong. I tried encapsulating it in the try/catch block but that doesnt work

Error reports happening on the first line, LoadAssetAsync

[cedar verge]

I don't think this is the most comfortable for the user. On Clash Royale for example, my inspiration, a very quick 0.5s slide of 100 is enough to turn the page. Menu switching is very intuitive on this game.

[wheat cargo]

That is strange, the only thing I can think of is that they are manually logging the exception just like you are trying to do

[cold parrot]

Does maybe the Addressables.LoadAssetAsync<T>() already have a try/catch?

Meaning what you want is probably the default behavior

[fiery saddle]

its unity code but going 2 levels deep, doesnt seem like it

[fiery saddle]

Thats the check for success part, i had log in it and it is reached
my problem is that unity pauses game if it happens

[wheat cargo]

Do you have error pause on in your console?

just turn that off

it won't happen in a build either

[fiery saddle]

..., yeah its the console

🤦‍♂️

[wheat cargo]

lol it has to happen at least once to realize

[fiery saddle]

I dont even need try/catch, everything worked even before

[stark plaza]

I think I may have misunderstood something... I'm trying to make a grid system but with 3d gameobjects. Since I'm making a tactics game I need like a GridState but I'm not getting anything useful info from the tilemap
My palette is just a simple cube

  tilemapLayers.AddRange(GetComponentsInChildren<Tilemap>());
            foreach (var tilemap in tilemapLayers)
            {
                ScanTilemapLayer(tilemap);
            }
        }

        private void ScanTilemapLayer(Tilemap tilemap)
        {
            foreach (Vector3Int pos in tilemap.cellBounds.allPositionsWithin)
            {
             //Nothing in the tilemap.cellBounds.allPositionsWithin

[steady bobcat]

Use Awaitable or UniTask instead of Task!

[fiery saddle]

why?

[steady bobcat]

Both are better suited for unity than Task and should produce less garbage. Both offer replacements for common coroutine stuff too.
Awaitable is 2023+ however

[stark plaza]

Do I need like tilemap collider or it will never work?

[dusk apex]

You aren't doing anything Physics related so I don't see the reason why you'd need a collider or whatnot.

[stark plaza]

I'm doing something like this but code aboves doesn't find any tile

[dusk apex]

With the data you've shown, you ought to simply check if the loops have got any data at all first by logging the number of tile maps in the layer or contents of the all position within.

[fallow quartz]

If I have a Terrain and a decal, how can i do so the decal projects into it? I want only the terrain to be able but the problem is decal uses layers from mesh renderer and my terrain does not have it

[hexed pecan]

If it's not exposed in thet inspector, try changing Terrain.renderingLayerMask

[fallow quartz]

where do i do that?

[hexed pecan]

It takes a uint which you probably want to copy from a Renderer's rendering layer mask field

[fallow quartz]

Oh nvm im really stupid

I found it, thanks ❤️

[hexed pecan]

Ah so it is in the inspector

[fallow quartz]

yeah, i didnt even try to check terrain settings, just assumed it was only a mesh renderer option

[warm badger]

hi, here i want to rotate a object on all its axis, which depends on the input...but when it is rotated 90 on x and then i want to rotate it along the green axis, the inspector value turn _90, -90, -90) something like this...i can't put these values as i don't know these...i just have some arbitrary values based on the inputs...how do i use them to rotate it correctly? as an example you may take, i want to rotate it along the green line while it is rotated 90 on x

maybe i messed up the explanation

[hexed pecan]

With code or in the editor?

[warm badger]

with code

[hexed pecan]

It's still a bit unclear which space you want to rotate in

World vs local

Relative to its own Y axis or world Y axis, etc

[leaden ice]

This is a result of two things:

• Gimbal Lock
• Euler angles being a terrible way to track rotation.

Anyway as for the specifics of the answer to your question, you would have to get very specific about the nature of the rotation you want to do if you want a good answer here.

[warm badger]

i want it to rotate like this

based on my input

[leaden ice]

use transform.Rotate

it will rotate in local space of the object by default

[warm badger]

but that continuously rotates, right? but i have some inputs...let me clear it out a bit...

[versed shale]

hey guys im making a vr game and im using a animation input script that i borrowed and im trying to do a use reference but its not there

[leaden ice]

it doesn't continuously do anything. It rotates when you call it, by the number of degrees you tell it to rotate.

If you call it each fraem, it will rotate each frame by the amount you tell it.

[leaden ice]

wdym by "it's not there"?

also I don't see any references here

InputActionProperty is a struct.

[hexed pecan]

Is this your "zero rotation"? Like the default rotation you want it to be in

[leaden ice]

look at your console window

see if you have any compile errors and fix them

[versed shale]

i dont

[leaden ice]

also what isn't it right there?

[warm badger]

i have a glider,,,this is rotated 90 on x, as you saw in the vid...now when player presses right or left, the object will rotate on its local yaw and local roll axis

[versed shale]

theres suppost to be a checkbox that sayss use reference

[leaden ice]

transform.Rotate(0, yaw, roll)

[leaden ice]

press the ...

it's probably in there

or press the + and then it might be in there

[warm badger]

actually its glider...it will stand straight when it is on ground, again will lie like this when flying

[versed shale]

got it thank you

[warm badger]

something like this is happening

when i press forward a bit...it starts to rotate forever

[hexed pecan]

Are you using a controller

[warm badger]

i just want it to rotate, when i press, and stop when i don't

[warm badger]

right now a keyboard

[hexed pecan]

When you press nothing , should it return to zero rotation or stay where it is

[warm badger]

as you see in the code, i am adding up the value while i am pressing to accurately rotate it based on the input

[hexed pecan]

Does that answer my question though?

[warm badger]

yeah yeah

[hexed pecan]

Rotate adds to the rotation so maybe that's not what you want here

It doesn't just set the rotation to the given values

[warm badger]

hmm, it seems like it,,,i can't find a way out

[hexed pecan]

transform.rotation = Quaternion.Euler(_, _, _)

Or set the base rotation first and then apply additive rotations with Rotate

Latter is probably better

[leaden ice]

so tie it to your input.

[warm badger]

like i said, it should set the rotation value, but Rotate doesn't set it, just adds it on top, i guess

[leaden ice]

you are tying it to these variables for some reason

and adding to the variables

so the variables end up causing continuous rotation

you want to either:

• add to your variables then SET the rotation based on them
  or
• use transform.Rotate directly with your input

e.g.

transform.Rotate(x * Time.deltaTime, 0, z * Time.deltaTime);```

(you only have two inputs so it's not clear how you plan to control 3 axes of rotation with only 2 inputs)

[warm badger]

when pressing left, right, the object will rotate horizontally and also will rotate a bit on roll axis

[leaden ice]

Is this you telling me what's happening with your current code or what you want to happen?

[warm badger]

i wanna do the first one, i am adding my input value to a vector, and then want to set the rotation which will show the object in the gameplay according to the vector3

[leaden ice]

Ok but your problem then is you will run into gimbal lock

this is a classic case of gimbal lock

[warm badger]

it happens, i want it to

[leaden ice]

relying on euler angles to do this is not going to work out

if(Input.GetKey(jumpKey) && readyToJump && grounded)```

it's because you're using GetKey which is true for all the frames during which you hold it

so depending on how long you hold the key and how long you are grounded, you will get different behavior

you should use GetKeyDown to detect only when you first press it

[warm badger]

it is kind of, i want to use the transform.Rotate and also want to set the value...hybrid

[leaden ice]

Why are you so married to the idea of using euler angles

[hexed pecan]

You shouldn't use code that you don't understand

Won't learn anything that way

And it's almost impossible to help (without spoonfeeding) then

Ah yess delete the messages and make me look like a skitzo

[warm badger]

i will give a brief what i am trying to achieve....

the object is rotated 90 on x axis

press up, down key --> accumulate the input and then set the value to x axis
press left, right --> accumulate two values, one for setting to its local yaw axis, another for setting on its local roll axis,...can you help me with this now...

[leaden ice]

would this become easier if you make two objects

a parent object and a child

I'm still having trouble following exactly what the desired gameplay/control feel is here.

[warm badger]

no, think like it is a glider...(actually it is a glider)

you want to turn right --> glider will rotate on its yaw and also on its roll a bit
you press up --> glider rotate downwards like a plane going down

[leaden ice]

with a glider or plane I would expect right/left to control roll and up/down to control pitch

yaw would be a third control if you have it at all

but it kinda sounds like you want the yaw control to work based on the world space y axis

but the pitch and roll to work in local space

[rigid island]

probably layer order issue? hard to tell also not a code question

#💻┃unity-talk probably better. You'd have to show the setup to be sure.

[worldly viper]

alright

[warm badger]

yeah yeah

something like this

i can't get over it, any suggestion?

[karmic stone]

for me at least, if i press up while contrlling a glider, my glider should turn up, and i start to lose more speed

if i turn down, my glider should turn down, and pick up speed

if i turn left and right, my character should lean, and i should start turning slowly in that direction

if you want it to work this way i would change the rigidbodys gravity constant to "imitate" having a glider, thenn making your forward velocity constant, and slows if your x rotation is above 0, and speeds up if you go below 0, and if you turn, slowlly turn the character/camera in the direction over time

normally, when controlling something like a glider in a game, you dont accumilate input alll together, you just apply it as you get it, then use what the character currently is doing after the input to move your object

[wheat spruce]

It's because those things don't exist

Unless you have something named PlayerCam that error is bound to happen

[still jungle]

how you tryed to fix it

[rigid island]

what is "something"

[vestal arch]

is it a class?

[rigid island]

this isn't names of cameras

[wheat spruce]

That error disagrees

[rigid island]

its classes

You might need to do beginner scripting in https://learn.unity.com/pathway/unity-essentials

learn what components are n other coding c# essentials

[pastel halo]

is it possible to nullify an abstract class (non mono)?

I'm having this weird bug where it's not finding null slots, but then it is?

On a weird note- anyone ever have an issue where you save and compile, but the code doesn't work? But when you add a debug log and recompile and run the game, suddenly it registers?

I'm also having this "if you click on a class in the inspector, the logic breaks" but when you click off (cannot see it in the inspector) it stops breaking?

These are two strange issues that seemingly affect my question partially

[vestal arch]

what do you mean by "nullify"?

[pastel halo]

like set equal to null

[vestal arch]

classes are reference types, so yes

[pastel halo]

it makes sense when its a mono since you have to actually provide an object. but as a pure class created through new() it seems like it has issues

[vestal arch]

monobehaviours aren't really special in that sense

[pastel halo]

weird. for example this wasn't working but then suddenly started working as soon as i began debugging it.

 // ✅ **Explicitly create empty slot instances**
                    var emptySlot = new ItemSlotInfo(null, 0)
                    {
                        gridIndex = i,
                        itemIndex = i
                    };

                    Debug.Log($"Creating empty slot: {key}");

                    emptySlot.item = null;

                    if (emptySlot.item == null)
                        Debug.LogError($"NULLIFIED SLOT");
                    else
                        Debug.LogError($"WAS NOT NULL!!!!");

                    items.TryAdd(key, emptySlot);

with the new i explicitly assign null

        public ItemSlotInfo(ConcreteItem newItem, int newStacks)
        {
            item = newItem;
            stacks = newStacks;
        }

then again you see i assigned it under the debug log, and it worked. it seems like it needs to be set twice to register

[vestal arch]

that's not really a thing that happens

code generally does what you tell it to do

not necessarily what you mean

[pastel halo]

with my code, shouldn't it apply null within the new statement? i.e. the emptySlot.item = null; is redundant?

[vestal arch]

it should, yes

[pastel halo]

ya now it's working, its so odd. I must be missing something or there's a compilation issue

[vestal arch]

i mean if "empty slot" is a common situation, you could even omit it from the constructor, it'll be defaulted to null (though i'm guessing that's not a common enough situation to justify it)

what's ConcreteItem?

[pastel halo]

I definitely know there's a consistent issue with this one class i have, where if selected in editor (mono) it will bug out

Concrete is the unabstracted version of Item

[vestal arch]

ok, but what is it

[pastel halo]

because abstract cannot be instantiated

sec

[vestal arch]

a class or a struct

just its declaration will do

[pastel halo]

a class that just inherits item

public abstract class Item

public class ConcreteItem : Item

[vestal arch]

does it inherit any equality overloads?

[pastel halo]

Concrete is empty, it just inherits and unabstracts thats it

    [Serializable]
    public class ConcreteItem : Item
    {
    }

[vestal arch]

what's the point of Item being abstract then lol

[pastel halo]

polymorphism apparently

[vestal arch]

well no, that's unrelated

if Item doesn't have any abstract members, why is it marked abstract?

[leaden ice]

your issue is that Unity's serializer doesn't support null

it will always create an empty/default object

It therefore also doesn't work well with interfaces and abstract classes

[pastel halo]

probably because i was treating it like a template, then having intermediate classes tack on functionality. wanted to keep some kind of root blueprint type class that was not accessible

[vestal arch]

you can do that with a non-abstract Item as well

[pastel halo]

O gotcha, i'm stuck on the issue of using "stacks == 0" as a check vs "slot.item == null" as the check

[hexed pecan]

[SerializeReference]is your friend if you need to serialize a null value and/or abstract classes and interfaces

[vestal arch]

how does that work if a class/struct doesn't have a zero-param constructor?

[pastel halo]

what do you think is better to dictate whether an inventory slot is empty- it being "null" or the stacks being zero?

b/c it seems like this null thing is an issue, whereas 'stacks > 0' has to be true for something to "exist" though i'm trying to futureproof/predict any potential bugs

[leaden ice]

still just creates a default valued object

[vestal arch]

you could have a designated EmptyItem, like old minecraft
not saying that's better but that is another alternative

[pastel halo]

Also, is the abstract Item a bad thing to have, like adding a redundant step? And I should get rid of it, and only have "ConcreteItem" (rename to Item) and make that un-abstracted?

[vestal arch]

oh unity uses reflection to make the object, doesn't it

[vestal arch]

yeah, there's not really a point in separating that in 2 steps

[leaden ice]

something like that

[vestal arch]

it's not bad; it's just unnecessary

[pastel halo]

oic, so polymorph from concrete and get rid of the inherited one? Just making sure this doesn't become a potential lock out issue, where i can't undo this lol

one class, "Item" (non abstract) as the root for all things*

[vestal arch]

yeah that's fine

[pastel halo]

ok. I believe that makes sense, i can always just append from that level forward

when you say 'empty item' what would the context be?

would that be some kind of id tag? like "groupID" and then i assign "emptySlot" then first or default/contains to find the first field ofthat type inside the inventory?

I could add a string field like that here in the slot:

   [System.Serializable]
    public class ItemSlotInfo
    {
        public int itemIndex; // The index in the backend data
        public int gridIndex; // The index in the visual grid
        public ConcreteItem item; // The item in the slot
        public int stacks;

        [Header("Shop Data")]
        public ulong itemCost; // the cost in iron
        public string itemID => item?.itemDefinition.itemID ?? string.Empty; // Convenience for accessing itemID

        public ItemSlotInfo(ConcreteItem newItem, int newStacks)
        {
            item = newItem;
            stacks = newStacks;
        }

[vestal arch]

no clue what you mean or what you're asking tbh

[pastel halo]

#archived-code-general message

[vestal arch]

yeah i know you're replying to that

but i don't know what you're asking lol

[pastel halo]

previously i was adding/removing dynamically. but now im prefilling a ton of empty slots. this was a new trade off because of the ui/data desync and some edge case issues

[vestal arch]

do you know how minecraft used to do it? (im not sure if minecraft currently still does it)

[simple idol]

you will have a script that allows you to move with an azerty keyboard ??

[pastel halo]

what im saying is 'how can i detect if a slot is empty, since null detection seems to be an issue' due to unitys caveats

i do not

[vestal arch]

so before, your inventory was variable size?

[pastel halo]

it still can resize. but previously it was toatlly empty list. as you get items/drop them it resizes

but conflict with UI slots vs resizing dict. plus its not performant doing that many operations

[vestal arch]

what's your inventory model here? im confused

[pastel halo]

better to "store empty slots" apparently and pay that cost

[vestal arch]

if it's not a fixed size with a fixed ui, it wouldn't make sense to show empty slots from a UI perspective, no?

[pastel halo]

generate a bunch of slots. the problem is adding items. i dont know how to detect if a slot is "empty". it finds an "empty slot" aka a pre-existing one, then writes data to it

so the ui now matches the data. if there are 6 inventory slots, there are 6 ui slots as well

so they are directly correllated

but since i cannot really be like firstDefault(x => x.slot.item == null) or something like that, need another way to indentify a "slot is empty" within that dictionary

[vestal arch]

step away from your implementation for a sec. what are you going for? what's your inventory model?

[pastel halo]

ok, its an inventory system where you can store items. The inventory size can scale as you add/remove bags. like 10 -> 12 or 12 -> 5, depending on what is equipped.

This will automatically call the items.dictionary to generate new "empty slots" so that there is "space" to add items to. You cannot add items to a non-existent slot. So 12 inventorySize means 12 slots that items can potentially go into.

You can also change the positions of items in the UI via "gridIndex". itemIndex referred to the link between UI and data, as previously you could have more UI slots then actual items (6 slots in ui, but have 0 items in backpack, aka your bag is empty, but you can hold up to 6 items). I'm in the process of moving away from that.

Right now, I am trying to figure out how to say "these slots are empty. there is no item data in them". but need a way to "tag" it as such. Right now i don't have a field that does that. I was attempting to do if(slot.item == null) but that clearly has issues, so I need another solution.

what I thought you had suggested was some kind of string tag. like all inventory slots will be automatically assigned "emptySlot" so that a forloop can easily loop over it and find those and just pick the first one then overwrite slot.item = newItem and slot.stacks = newStacks.

I believe its just a standard inventory? Kind of like VRising or minecraft? You collect items and can move them around visually in the inventory and they retain their position?

Only difference is if you alter the inventory size, it needs to recalculate that.

But the main issue right now is just "how do i assign that something is empty, because null doesnt work apparently"

[vestal arch]

ok so you don't actually have a list of slots, you have a list of item stacks that you map into slots, why not actually have a list of slots that items can be transferred between?

about the EmptyItem thing, it's just an extension of your Item with no data

or perhaps you could assign a magic number for item id

[pastel halo]

public SerializableDictionary<string, ItemSlotInfo> items = new();

[vestal arch]

like id = 0 means it's empty

[pastel halo]

o gotcha, that makes sense, but seems like a permutation of just checking the stack count. unless that's slightly less expensive

[vestal arch]

you should not care about what is expensive or performant at this scale

you would need to have millions or billions of slots for it to matter

[pastel halo]

gotcha that's true

[vestal arch]

your focus should be on what makes sense and is easy to understand and work with; don't fall into the trap of premature optimization

[pastel halo]

the items dict above is the key GUID (not really used, but apparently helpful for quick lookups in the future) and the ItemSlot itself which contains subfields like item and stacks

the value is what is targeted

for sure, just trying to balance things out

and also i dont want to manage a ton of fields at once. thats more the concern

less is more

a 0/1 binary flag would work though for sure. either its empty or its not. that def makes sense

[vestal arch]

that's called a boolean

[pastel halo]

true that is even cheaper lol

[vestal arch]

you could make it a property that just checks that stack count

[vestal arch]

it isn't

it just makes more sense to work with

[pastel halo]

interesting. but ya sounds like alot of ways to approach the issue

easier to come back to in the future for sure

the reason i mentioned performance was because i was already starting to see some issues. but in regards to instantiation. which is why i swapped over to 'pre-generated slots' rather than add/remove constantly

started to see a few seconds of delay when switching tabs which is a big problem

[vestal arch]

none of what's been mentioned would be the bottleneck in something like that

[pastel halo]

i'll stick with your suggestion though its straight forwards

[vestal arch]

like i said before; don't fall into the trap of premature optimization
if you're seeing performance issues, do profiling to see what the issue actually is

[pastel halo]

sounds like adding that property/field and then converting concrete to item and removing abstraction should fix alot of issues

i think its because its instantiating alot of things. i still have to learn how to pool some stuff like that. so its more of a 'pregenerate, then toggle on/off'. that should fix the issue in theory

[vestal arch]

12 slots is not a lot

[pastel halo]

alot of interesting trade offs. memory vs framerate

o no, its like 60 that this had an issue

instantly generating and filling all the data

[vestal arch]

60 is also not really a lot

[pastel halo]

hmm. its probably beacuse i destroy them all, then regenreate

each time a shop tab is clicked, it does that

[vestal arch]

oh yeah that's.. not great

[pastel halo]

ya im sure thats why. its doing too many operations in a milisecond

pooling/something like it should solve that

[vestal arch]

it's probably in the gameobjects part though, not in the constructing part

[pastel halo]

yea

filling the data should be cheap

as i understand it

instantiating seems expensive

cool, i'll give those suggestions a shot, thanks

[vestal arch]

very much so

[unkempt jacinth]

Hey everyone,

I'm trying to get my first-person character controller to move smoothly on a moving and rotating platform (like a ship) without making the player a child of the platform.

Right now, I’m using a raycast to detect if the player is standing on the platform (by checking a specific layer), and then I apply the platform’s movement and rotation delta to the player in LateUpdate().

What I’m Doing

1. Raycast Down from the player's feet to see if they are on a platform (using a tag or layer).

2. If they’re on a platform:

Store the platform’s position and rotation from the last frame.

In LateUpdate(), calculate how much the platform has moved and rotated.

Move the player by the same position delta and rotate their Y axis to match the platform.

3. If the player jumps or steps off, the raycast no longer detects the platform, so they stop moving with it.

The Problem

It kinda works, but the player slides when the platform moves, especially when it turns only. Since I’m using a CharacterController, I’m applying movement using Move() instead of setting transform.position, but it still doesn’t feel right.

The sliding only happens when the platform turns, but its really slow. But after a while it builds up and than the character falls off

[vague cosmos]

What's the best way to trigger a function on another script? For example, i want to have a damage function that is triggered when it touches a damaging object, but the damaging object decieds how much damage to do, rather than having a different case for each object

[leaden ice]

Get a reference to it and call the function

[vague cosmos]

Thanks! I figured it out using on collision enter.

[leaden ice]

Yes...

You get a reference inside OnCollisionEnter

And call the function

[wheat cargo]

Do you think Unity will ever get built in support for serialized interface references?

[somber nacelle]

by "built in support" do you actually mean "draw a property drawer for it"? because you already can serialize interface references with SerializeReference

[wheat cargo]

And that works for unity objects that implement an interface?

I've used SerializeReference before but not for unity objects

[somber nacelle]

hey maybe consider providing all of the relevant information when asking for something instead of leaving out crucial information like that

[wheat cargo]

thought that would be implied, but you're right

[spark stirrup]

Why would my movement be causing my camera to move slowly? (yes I know this code is probably a mess and could be better)
https://pastebin.com/DZAY9jCp

[leaden ice]

how is your camera supposed to move?
Quickly?
Not at all?

Is there a script that moves the camera?

We need more details

[spark stirrup]

There is another method in the same script, and the camera gets slowed down significantly when ever the player starts to move. I can send that method as well, but I know it's this method that's the culprit

[leaden ice]

You should share all of the relevant code.

Share the full script

It's not even clear where HandleMovement is being called

[spark stirrup]

it's a really long script

[leaden ice]

that's ok

share it

[spark stirrup]

https://pastebin.com/JsNeqtsF

[leaden ice]

(that' really not that long)

[spark stirrup]

It is for me, usually mine are at most like 300 lines lol

[leaden ice]

Is the camera a child of the player object?

Or what

[spark stirrup]

yes it is

[leaden ice]

Ok so what do you mean by the camera moving slowly then?

Isn't it attached to the player?

[spark stirrup]

rotation

[leaden ice]

Doesn't it move at the same speed

Ok... see these are important details lol

[spark stirrup]

sorry miscommunication lol

[leaden ice]

ok one big problem is this:

        float mouseX = Input.GetAxis("Mouse X") * MouseSensitivityX * Time.deltaTime * 100f;
        float mouseY = Input.GetAxis("Mouse Y") * MouseSensitivityY * Time.deltaTime * 100f;```

you should not be multiplying Time.deltaTime into your mouse input

mouse input is already framerate independent

this is going to introduce problems such as the look speed changing when your framerate changes

[spark stirrup]

i added that to try and fix the issue so that's not causing it I just forgot to remove it

[leaden ice]

That's also the only code that seems to deal with rotation

[spark stirrup]

yeah it's something in the movement code

[leaden ice]

and you only seem to do up and down rotation on the camera directly

the rest of the rotation is rotating the player itself

Is it vertical or horizontal rotation that is slow?

[wheat cargo]

The ApplyViewBobbing method is the method moving the camera

[leaden ice]

That is indeed moving the camera but not rotating it

[spark stirrup]

both, but it only happens with the controller

[wheat cargo]

right, but they asked about moving, unless they really meant rotating

[spark stirrup]

i meant rotating

[leaden ice]

ok... more information that would have been helpful at the start.

[leaden ice]

Yeah read the convo

[spark stirrup]

i just learned this while testing lol

[leaden ice]

ok so ironically gamepad input DOES need Time.deltaTime

mouse should not have it

but gamepad in Update needs it

that's your issue probably

[wheat cargo]

I guess I'm blind, my bad

[leaden solstice]

Why.. are you using new input system but reading all axis and mouse stuff separately

[leaden ice]

yeah that's a whole separate issue

[spark stirrup]

I'm just switching over to it

like just now

[spark stirrup]

this just slowed down the camera rotating left and down even more

this is what i did

        float gamepadX = (lookRight != null ? lookRight.ReadValue<float>() : 0f)
                       - (lookLeft != null ? lookLeft.ReadValue<float>() : 0f) * Time.deltaTime;
        float gamepadY = (lookUp != null ? lookUp.ReadValue<float>() : 0f)
               - (lookDown != null ? lookDown.ReadValue<float>() : 0f) * Time.deltaTime;

[leaden ice]

yes it will slow it down. You need to multiply by a sensitivity value as well

it won't be framerate dependent anymore though

which should fix your problem

[wheat cargo]

Just curious, how is mouse input frame rate independent?

[leaden ice]

Mouse input comes in as "the amount the mouse moved this frame":

[spark stirrup]

moving still slows it down, and its slower in the negative directions and faster in the positive directions

[wheat cargo]

Ahh duh lol

[leaden ice]

the faster in positive direction is probably due to your weird little math with the two separate input axes instead of just making a single 2D input vector or two 1d axes

[spark stirrup]

how do I switch over?

[leaden ice]

make a single action for "Look"

set it to
Action Type: Value
Control Type: Vector2

bind it to the joystick you want

And in your code you just do:

Vector2 lookInput = lookAction.ReadValue<Vector2>();```

[simple idol]

qui parle francais??

[leaden ice]

Anglais seulement

[simple idol]

ok

[spark stirrup]

This completely fixed all the issues

should I be doing the same thing for movement?

[leaden ice]

yes

if it's a 2d joystick input

[pallid girder]

Hey does anyone know a good tutorial for GPU instancing

[spark stirrup]

the bug just randomly came back and I didn't even change anything

and now its gone? i am so confused

[leaden solstice]

Are you doing anything specific or just writing shader support GPU instancing

[pallid girder]

i have a lot of trees and grass in a terrain and i feel like i should optimize it

i tried following a tutorial because ngl i dont know how to code but i can't figure out why theres an error in one of the lines

[leaden solstice]

#⛰️┃terrain-3d or #archived-shaders possibly more appropriate

[spark stirrup]

it's back 😭 i'm messing with how sprinting is triggered in my code, and that seems to make the bug come back and I have 0 idea as to why

[pallid girder]

ohk thanks

[dense pasture]

seeding Random.InitState from one scene affects randomization uniformly in all scenes even if they aren't loaded at the time of init?

[leaden ice]

Unity's Random state is completely static

it doesn't know or care about scenes

[lean sail]

what does a scene have to do with Random? its a static method and doesnt care what scene u are in

[dense pasture]

making sure there isn't some quirk to it

thanks

[dense pasture]

if i had a dime for every api, framework or engine that these very rudimentary things that should be predictable, weren't...

[lean sail]

The docs will sometimes mention if theres anything weird, but the unity stuff is mostly fine

[leaden solstice]

What are you using Random.InitState for tho?

[dense pasture]

roguelike logic

need seed control

[leaden solstice]

I'd recommend just using System.Random instance

You might never know what consumes static random

[dense pasture]

is there some low level code calling on it in unity itself? that seems like exactly the kind of quirks i was talking about

but more or less it would just only matter for the navigation map gen

i'd init the state right before that

[leaden solstice]

I don't think it would, but if you have choice to avoid footgun why not

[steady bobcat]

i presume UnityEngine.Random is for user code only and not engine
but i do also think its better to use a specific System.Random instance

[dense pasture]

yeah that would be a sure thing anyway

[steady bobcat]

or find some other random num generator thats consistent with seeding like mersenne twister

[leaden solstice]

That too if you need to ensure consistency across versions

[spare swallow]

Hey all, not sure where this question is appropriate but I am just wondering if anyone knows why the "FBX Exporter" package would be exporting no models, I am specifically trying to export a terrain but I've tried all sorts of meshes to no avail. It always exports as a very small file which I would assume couldn't realistically have a mesh ~12kb or so. Any help or advice would be appreciated!

[leaden ice]

Is FBX exporter supposed to support terrains?

https://docs.unity3d.com/Packages/com.unity.formats.fbx@5.1/manual/features-behaviors-exported-attributes.html

Doesn't look like it

[spare swallow]

I believe so, I've seen guides showing it be used as such. But I have also tried exporting other meshes to no avail.

[steady bobcat]

what about gltf export 🤔

it is vague about support but may be worth a try: https://docs.unity3d.com/Packages/com.unity.cloud.gltfast@6.10/manual/index.html

[cursive moth]

Hey @heady iris and @hexed pecan, sorry for the ping, you were trying to help me a while back with a rather weird issue, having custom defaults for json values that get overriden if something's defined in the config, you can see more details in the message I am replying to.
I managed to solve it by using [OnDeserializing] attribute(thanks DeepSeek).
E.g. would be my color class:

[OnDeserializing]
private void Reset(StreamingContext context)
{ R = 0; G = 0; B = 0; A = 1; I = 1; }

Now I can simply assign the default color value in the ResetToDefault method:

public void ResetToDefault()
{
    ColorOverLife = DefaultColorOverLife;
}

And it will use correct values in all scenarios:

Fully defined color(RGBAI) -> Use those
Partially defined color(e.g. BA) -> Use value defaults from the data type(in this case Color)
Not defined in config -> Use the DefaultColorOverLife defined in the editor

Before this, I had to have a fairly annoying workflow:

public void ResetToDefault()
{
    ColorOverLife = null;
}
public void Load()
{
    ColorOverLife  ??= DefaultColorOverLife;
}

Where ResetToDefault got called right before loading the config and Load got called right after loading the config.
As I said before, for a solo dev this isn't a big deal, however, considering the fact this is meant to be used as more of a framework, it is quite annoying.
Pictures

1. Fully defined(Uses everything from config)
2. Partially defined(Uses config values+default color values)
3. Not defined(Uses the in editor defined default values)
   Thanks for some useful attempts and suggestions either way, hope this helps you in the future!

[spare swallow]

I appreciate the suggestion and will definitely check it out, at-least temporarily I found a user-made script which compiles terrain to .obj which works for what I am currently doing. Thank you though!

[cursive moth]

Forgot to reply to the question 🤦‍♂️

[spark stirrup]

I'm using the UI Toolkit to build my menus, how can I use an event system with it?

[leaden ice]

#🧰┃ui-toolkit has its own internal event system and doesn't use the UGUI one.

[spark stirrup]

How does it work?

[somber nacelle]

it JustWorks™️ what are you actually trying to accomplish

[leaden ice]

Have you checked the documentation?

[spark stirrup]

Have a controller switch and click different buttons

[spark stirrup]

there's like nothing on there

[leaden ice]

https://docs.unity3d.com/6000.2/Documentation/Manual/UIE-Events.html

https://docs.unity3d.com/6000.2/Documentation/Manual/UIElements.html

Note the UI Toolkit docs have more or less been folded into the main Unity docs

Since it's a core package

[spark stirrup]

I'm confused on what I'm looking for in the docs. Is this what I'm looking for? It doesn't really tell me how to use the Standalone Input Manager:

https://docs.unity3d.com/6000.0/Documentation/Manual/UIE-Runtime-Event-System.html

[somber nacelle]

the Standalone Input Manager is used with the ugui Event System.
This is from the link you just sent, you should maybe try reading the information:

The Input System package offers enhanced configurability compared to Input Manager. You can use the project-wide actions asset to set up how NavigationMoveEvents, PointerMoveEvent (“UI / Point” action), PointerDownEvent, PointerUpEvent (“UI / Click”), WheelEvent (“UI / ScrollWheel”), NavigationSubmitEvent, and NavigationCancelEvent are generated for UI Toolkit.

there's also a handy table directly below that which tells you what you need

[spark stirrup]

The Standalone Input Module dispatches events to UI Toolkit elements. This is why I thought I needed it.

[somber nacelle]

did you read the table directly above that

that is for if you are using both ugui and uitk with the input manager (not input system btw)

[spark stirrup]

UI Toolkit elements with Input System package so I need to use the Input System Package (New) or Both for event handling

which is just the The Standalone Input Module

[somber nacelle]

please read it again

[spark stirrup]

Yes I know it says no scene components required but I want to use the active input handling

which it says to use the input module

[somber nacelle]

wdym "i want to use the active input handling"? that's just a setting in the project settings that determines whether you are using the input system, input manager, or both.

if you are using just uitk and not ugui then as the table says, there is No Scene component required

[spark stirrup]

I didn't know that was a setting so I was confused

[somber nacelle]

then read the information on the page

there is an entire section titled Set the active input handling system

[spark stirrup]

Okay, but nothing is being selected when I hit play and my controller does nothing. Also my input settings looks completely different than on the website:

[somber nacelle]

what version of unity are you using and what version of the input system package do you have

[spark stirrup]

2022.3.20, and 1.7.0 which is the latest

[somber nacelle]

yeah mention that next time. you need an event system
https://docs.unity3d.com/2022.3/Documentation/Manual/UIE-Runtime-Event-System.html

and for future reference, when looking at the docs make sure to change to the version you are using so when you link documentation you are reading you are linking the correct version so nobody assumes you are using a different version

[spark stirrup]

Still nothing gets selected at all when I add those

[somber nacelle]

Hey guys, how to fix this light problem?

[latent latch]

If there's an actual coding problem, post away, otherwise #archived-lighting. Also be more descriptive to the problem

[unkempt meadow]

OK so I have a question for y'all:

I have some wall sprites in a 2d game. I need to change the size for each of the wall blocks I place in.

The more performant but tedious way to do that would be to manually modify each of the box colliders to match the sprite (can't do polygon collider cause I modify the sprite renderer values, not transform)

Instead, I just wanna make a script that will modify its box collider 2d value on x and y based on the sprite renderer values

This is technically less performants cause I got all these blocks with a script on each of them but am I worrying too much about this? It's a webgl game so I'm careful but what do you guys think about this?

[vestal arch]

for simple stuff like this, don't worry about performance until it becomes an issue; once it does, do profiling to figure out where the issue actually is, rather than doing random optimizations

[unkempt meadow]

I mean, it's not a "random" optimization but sure, I would like that to performs well for lazyness reasons so I will try it

[vestal arch]

but you can't be sure if it's actually the bottleneck that's causing performance issues unless you actually profile it

what you're suggesting is still most likely performant enough

computers are fast

[unkempt meadow]

yeah it's supposed to work on mobile browsers as well

webgl

[vestal arch]

still pretty fast

Good afternoon everyone, I'm making my RTS now, and I have a problem, I want to make squads like in Wargame/broken arrow, but I don't understand how to implement it in the code

[heady iris]

Can you explain how squads should work a little more?

[latent latch]

I'd start looking into tutorials how to select your units. I've seen quite a few of those on youtube

then spend the next year or two perfecting your swarm AI pathfinding

[mild gazelle]

You have a squad, it has 6-12 soldiers, they have common health, but different weapons, one has a rifle, the second has a machine gun, etc., and they are one unit, moving, attacking and all that as one unit
maybe you have seen such units in world in coflict, wargame red dragon or brocken arrow.

Like for example here, one squad, it has 6 soldiers, and in the game they act as one unit, they have the same health, but different weapons that can be changed.

[eager fulcrum]

Hey, something weird is happening with my tilemaps

here, my player can't move to the right

i need to jump and then try again

[pastel halo]

Can anyone explain this weirdness?

This is the "Clicking on a script inside the hierarchy causes logic to break (permanently sometimes)"

When you don't click on the script it works. But as soon as its seen in the inspector, all logic breaks permanently. The code looks totally normal and nothing stands out.

I think it may be a problem with unity's serialization or how it renders things?

Notice how when I don't select anything "UI/Inventory" related it's normal (empty slots).

But as soon as I click "Chest_Basic" which has UI And data linked, it breaks. This happens with any ItemSlot (my system) based classes. It makes no sense.

Sometimes it un-breaks when you deselect. When I run a build, since you cannot select anything, it's technically not an issue. But it makes debugging very difficult if I accidently have the class(es) selected and hit play, or want to see the fields for debugging (rather than blackbox where I can't see anything at all).

Any ideas on what causes this and how to fix it?

I've tried "hide in inspector" on all fields. But just selecting the class causes the breakage. And it's multiple classes related to a specific UI setup.

Any other UI classes have no issues. It's really bizarre.

[leaden ice]

If you click on an object and things break, it's likely due to code you have either in OnValidate or if you have custom ISerializationCallbackReceivers

or code in a custom editor

you also seem to have some kind of plugin adding buttons to Transform - any plugin might cause issues as well

[pastel halo]

hmm interesting, i'll check to see if I have any OnValidate code hidden somewhere

O ya, that's just custom resets. I'd be surpried if that causes it, since no other classes are breaking

[latent latch]

Related to this question, I was wondering how sturdy is the OnPointerEnter/Exit methods in terms of firing?

[leaden ice]

probably not but - just listing possibilities

[pastel halo]

ya I'll try to narrow it down

[leaden ice]

they're totally reliable in my experience, as long as things are set up properly

[latent latch]

I'm like paranoid that OnPointerExit won't fire and screw over some logic

[leaden ice]

THere actually are some weirdnesses

Especially around things like:

• locking and unlocking cursors
• moving the camera instead of the pointer
• focusing in and out of the game

You might want to check on these edge cases

[latent latch]

Yeah, probably best to just raycast it manually

[rigid island]

one weirdness to keep in mind, if you use Physics raycaster to have those events on colliders, keep in mind UI elements can cover colliders with rayhit from Event System

[leaden ice]

locking and unlocking cursors
moving the camera instead of the pointer
For these two in particular there are unfortunately behavioral differences between the old and new input system input modules :(((

[pastel halo]

Would an abstract inheriting another abstract cause UI breakages?

[latent latch]

You really think im going to read that

[proven oriole]

Mistake im editing now

[rigid island]

large code should not be posted in the chat but as links

look like a #archived-networking question anyway

[proven oriole]

Kk

[proven oriole]

Its not i dont think, the issue is something to do with the unity editor

[leaden ice]

What kind of UI breakages? Like in the inspector? Not in general.

[pastel halo]

ah ok, I'm slowly isolating the issue. It's definitely UI related

[rigid island]

then you outta explain the issue before even posting code

[proven oriole]

I was i just accidentally sent it as i said

[pastel halo]

something to do with my "refreshUI" is breaking when the class is selected. hopefully soemthing mundane since I dont have any validation methods that im aware of. or any fancy calls

[proven oriole]

For some reason, this code runs the camera smoothly from within the unity editor, however when i build and run it it has a laggy, slight rubberbanding nature (will attach video in a min). Anyone know what may be causing this?

https://paste.mod.gg/betilbpdgwmq/0

[leaden ice]

do you have a Rigidbody on the object you are rotating with this code?

[proven oriole]

On one of them, yes. The player

[leaden ice]

ah I also see this is networking related

[leaden ice]

rotating an object with a Rigidbody directly via the Transform will break interpolation

[proven oriole]

Kinda, but to my knowledge it is not caused by the networking

[proven oriole]

Causing it to look how it does?

[leaden ice]

it can cause it to be jittery yes

[proven oriole]

Gotcha, thank you very much

[leaden ice]

most likely you can just replace:

cameraParent.transform.rotation = Quaternion.Euler(0, yRotation, 0);```
with:
```cs
theRigidbody.rotation = Quaternion.Euler(0, yRotation, 0);```

and that will preserve interpolation at least

[proven oriole]

Oh okay, thats simple

thanks

[willow pecan]

Trying to do a full body IK but the camera keeps going to the legs and the fingers are getting messed up. Anyone know a fix?

[rigid island]

where is the coding question exactly?

[willow pecan]

How do I make it so the camera stays at the head and not at the legs

[rigid island]

parent it to the head bone?

this is a coding channel..You can try #🏃┃animation

[pastel halo]

Ok I think i've figured out why. this goes back to my old question about the Item/ConcreteItem thing.

where "What is considered null in unity" when its not mono.

          // Ensure the item is fully visible if present
                    if (slot.item != null)
                    {
                        // Set item visuals
                        panel.SetIcon(slot.item.GetIcon());
                        panel.stacksText.text = slot.stacks > 0 ? slot.stacks.ToString() : "";

                        panel.TogglePreview(true);
                        panel.FadeIn();
                    }
                    else
                    {
                        panel.TogglePreview(false);
                    }

This line
if (slot.item != null)

From my tests (and afaik), it seems like null is never really null when its a class and not mono. If mono, you have to supply in the reference. If not mono, null just "clears" the data (empty state) but isn't actually "non-existent"

Though I don't get why not selecting the class vs selecting the class initializes things differently. That's still odd to me.

Now the preview is "correct" but backend its still doing that null check when clicking on empty slots.

I changed it from != null
to
if (slot.stacks > 0)
and that solved part of the issue.

I think it just stems from that null check problem

something must be loading/refreshing when clicking on classes in the inspector, then thats getting passed along to my if statements that check for "null"

ah i think i know why

My class is serializable. supposedly unity doesn't destroy serialized classes (non mono). it just clears the field like I thought. If it was non-serialized (default) then it would actually destroy/null it

[stark plaza]

Anyone knows how to fix this? I'm using rider and I hate it's putting the serialized flag up there

[rigid island]

wdym whats wrong with putting serializefield ?

oh you mean you want it inline ?

[stark plaza]

Yes

[leaden ice]

change your C# code style settings

[stark plaza]

Just the one with other flags before get this terrible lining

Something here probably

[rigid island]

seems like it

the one I found only adds comma for multiples

Im still new to rider sry 🙃

[steady bobcat]

If you put attributes and the field on the same line we are not friends 😆

[stark plaza]

same, it has power but it's giving me headache for formatting and swiggles ahahah

[rigid island]

I make an exception for SerializeField

[stark plaza]

even
Header
Serialized
property

is fine

[rigid island]

its tbh the only attribute I keep same line

[stark plaza]

but
Header, Serialized
property

i scream

[rigid island]

[SerializeField] private float t
[SerializeField] private float t 🤮

but I dont mind
[Header("meow")]
public float stuff

its weird

[pastel halo]

Yep, removing "Serializable" from item fixed the issue. Now it doesn't break the UI or logic anymore.
But now its a complete blackbox. Cannot see the item details at all.

Any suggestions on how to kinda work with those limitations?
Either I change the logic to use "stacks > 0" and serialize the "item" class so debugging is easier, OR I leave item un-serialized and can use "slot.item == null" because unity can now destroy it. Trade off between easier debug but altering the core func, vs more difficult to debug (can't see data) but simpler system. How would ya'll approach it?

[rigid island]

why dont you want serializable again ?

[pastel halo]

unity clears it to default but doesn't destroy it. so null checks will never work

its non mono

just a c# class

[rigid island]

ahh right embedded pocos always get initialized

[pastel halo]

yer had gpt confirm my suspicion since i've consistently seen this

[rigid island]

if you assign poco to null does it still do it?

[pastel halo]

it clears the data but doesnt removeit from inspector

its like the equiv of setting all fields to empty

it still exists

[rigid island]

oh yeah ig the inspector is just constantly initilizing it

[pastel halo]

that must be why

that'd explain why it keeps breaking when i click on it....

sheesh lol hidden stuff. may just be best to blackbox it as a 'poco'

its lame but wont have to deal with issues like weird re-initializiation

there's no debugs/errors thrown so it's been a nightmare

i'll def have to keep this in mind going forward

[rigid island]

I think you might be able to override the inspector for it and prevent that behavior

[pastel halo]

that makes sense, but most likely out of my scope of knowledge

[rigid island]

yeah making another flag/bool would probably solve some issue but its dirty

[pastel halo]

i do like setting things to null though, that's much easier than 'acess this field, check if stacks > 0' or doing id tags

ya, i guess i can just stick with debugs. wish there was an easier way to stop that initializing lol

o well, good to know

[rigid island]

yup, no easy way but custom inspector that overrides it would probably work

[craggy veldt]

isn't that's what [NonSerialized] attr is for?

it will stop unity from touching it at all

[pastel halo]

o like it can be serialized but the inspector won't refresh it?

or are you saying the equiv of 'just don't serialize it to begin with'

[craggy veldt]

no.. the editor wont touch it, that's it

[pastel halo]

o so I can have it exposed as a serializable, but block the inspector from refreshing/recreating it?

[rigid island]

afaik thats for types that already serializable but so you dont want them showing in the inspector

[pastel halo]

like see the c# class in editor, but prevent unitys inspector from acting on it and breaking the system (refresh/recreation)

[rigid island]

like [NonSerializable] public int someInt // wont show in inspector

[pastel halo]

o so its just a blackbox then? like hide in inspector?

[rigid island]

pretty much

[pastel halo]

or do you mean wont show in inspector as in, you can see it, but the inspector cant

[rigid island]

but if anything this one would've been better
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/HideInInspector.html

[pastel halo]

o ok, then its no different than not tagging it then

ya hide in inspector didn't work for serializables. that still caused breakages

but if there was a class i wanted to force hide then for sure

my issue is the inverse as ya know

'view in inspector, but block inspector from acting on it'

its purely for debug purposes

[rigid island]

yes, maybe make a property

but if its just for viewing in the inspector I wouldnt even bother

You can make a custom inspector if you really wanted to , that can prevent auto initilizing it

[pastel halo]

cool thanks, i'll look into that down the line

glad this seems to be resolved for now. alotta interesting caveats

[craggy veldt]

oh you want it to be serialized but not editable, or? im confused, sorry not following the conv above

[latent latch]

You need to wrap your serialized classes in some nullable type if you want to prevent unity creating an instance such as a List or Array

[rigid island]

The want to see it in the inspector but that comes with unintended consequences of unity always giving default values even when setting the data to null. They want to be able to null check which doesnt work on their class because unity inspector keeps initializing it

[latent latch]

Or ideally SerializedReference if they actually had support

[still jungle]

well you can always OnBeforeSerialize and OnAfterDeserialize to store that data in some serializable struct and reconstruct it in to object with custom logic after deserializing

[craggy veldt]

^ that

[still jungle]

so you will have controll how and when its recreated

but to use that you have to get good knowledge about SerializedObject and how it works with inspector so you dont get stuck

[latent latch]

[Serializable]
public class NullableRef<T> : ISerializationCallbackReceiver where T : class
{
    [SerializeField] private List<T> value;
    public T Value => value.First();

    public void OnAfterDeserialize() { }
    public void OnBeforeSerialize()
    {
        if (value != null && value.Count > 1)
        {
            value.RemoveRange(1, value.Count - 1); 
        }
    }
}```
I made that the other day

Fixes that bullcrap and cant be bothered waiting another decade for serialized references

Little funky but it's this or odin inspector

[shell oxide]

how can i add text spacing for each letter?
cause like B is bigger then I so i dont want I to have a universal 0.5 spacing for example..

float totalWidth = 0;
        foreach (char c in Text)
        {
            totalWidth += GetLetterWidth(c) * Spacing;
        }

        float startX = -totalWidth / 2f;
        float currentX = startX;

        for (int i = 0; i < Text.Length; i++)
        {
            char c = Text[i];
            GameObject letterPrefab = FindLetterPrefab(c);
            if (letterPrefab != null)
            {
                GameObject newLetter = Instantiate(letterPrefab, transform);
                newLetter.SetActive(true);

                float letterWidth = GetLetterWidth(c) * Spacing;
                float letterOffset = GetLetterOffset(c);

                newLetter.transform.localPosition = new Vector3(currentX + letterOffset, 0, 0);
                InstantiatedText.Add(newLetter);

                currentX += letterWidth;
            }
        }

this is how i save them

[leaden ice]

uhh what are you building here and why are you making whole GameObjects for each letter?

TMP can do custom spacing: https://docs.unity3d.com/Packages/com.unity.textmeshpro@4.0/manual/RichTextCharacterSpacing.html

[shell oxide]

a text system, each letter has its own gravity, my own 3d text system

[shell oxide]

no im making my own system 😭

[leaden ice]

Yes I see that, I'm wondering what the benefits are. Seems like a lot of work

[latent latch]

interesting, but if you just want to use textmeshpro you can just space the vertices out

[leaden ice]

There are also kerning pairs you can set: https://docs.unity3d.com/Packages/com.unity.textmeshpro@4.0/manual/FontAssetsProperties.html#glyph-adjustment-table

[latent latch]

probably other methods since the API is huge

[shell oxide]

it is a lot of work but i do require to make a whole text system

[latent latch]

Ah, yeah that looks like the better idea

[shell oxide]

its not for myself, im making a level editor

but there is a different problem

nothing changed

the dictionary does nothing

is the code right?

[latent latch]

idk have you debugged anything

dictionary looks fine from what I can tell

[leaden ice]

i mean it looks... sorta ok at a cursory glance but there's some missing context too

[shell oxide]

i can give any context just tell me what u need, here is the other functions

[leaden ice]

well you only have very small offsets

an order of magnitude smaller than the letter widths

so it might not be noticeable

[shell oxide]

but offsets are what change the letter to different way, i need the spacing which is width??

or am i not understanding my own code 😭

[mortal needle]

How can I calculate/predict the world position of a child after parent is rotated without actually rotating the parent?

[leaden ice]

Well can you explain better what part isn't working?

[shell oxide]

if i put spacing to 0.1 its equal to the same way it was before i added dictionary

wait a sec

i think my width are not right

[leaden ice]

Something like:

Quaternion rotationToApply = whatever;
Vector3 newLocalPosition = rotationToApply * childTransform.localPosition;
Vector3 newWorldPosition = parentTransform.TransformPoint(newLocalPosition);```

depends on the precise details of how you are calculating/applying rotation etc.

(this is assuming you are rotating by a certain amount not rotating to a certain new rotation)

[shell oxide]

i have to remeasure each letter 😭

im gonna come back if i have more issues

[pastel halo]

Ah, so I realize why I separated Item and ConcreteItem into two things. Now its serialized vs unserialized. (before it was abstraction, which is removed now)

The problem with using just "Item" directly is that unity will drop all non-serialized data. And my "salvage bag" has pre-injected data from a tool in its list. It got totally dropped because I changed all logic over to "Item" only (to fix UI/data breakage)

But since Concrete inherits from item, I can simply just redirect editor side/pre-injected data to using the serialized version, and use Item for all runtime instantiated data. That should in theory stop any UI/inspector breakages while preserving item data in both cases.

I should be able to pre-inject data that will stick (ConcreteItem) and use runtime data separately (Item).
Pre-injection is a way to save resources, the list is premade so it just reads it. Whereas if it was runtime only like the rest of the system, I would need to generate like 90 things instantly. It went from 3-5 second delay to instant when using a preinjected list.

Does that sound about right? Or is there a better method? I feel like that's the simplest solution that's scalable. Separating runtime and pre-injected data into two types, and just having one inherit the other (ConcreteItem : Item) so that they are the same thing (one is just serialized)

[foggy terrace]

Hi can I check how do I add more "Driven Axes" into the Cinemachine Input Axis Controller component?

[latent latch]

Well, you're constructing everything at runtime regardless if you're pre-defining your items so unless you're skipping over some process it should be the same in terms of loading

either case, you'll probably want some lazy loading / async method to not run into these spikes

[latent latch]

help would be very kind

[rigid island]

check package manager there is probably an update

2021 is kinda outdated tho

you should be on unity 6

at some point new packages/plugins wont support it. For mobile and console i think it matters to not fall too far behind

Using PlayerPrefs and set the amount of arrows you have in a hub world, and then after going into the first level a "Shooter" Script pulls the PlayerPref to set the current arrows equal to the PlayerPref, it looks like the PlayerPref is being set just fine but my shooter keeps saying I have 0 arrows available ```void Start()
{

    currentArrows = PlayerPrefs.GetInt("Arrows");
    
} ``` Here is the start code for the Shooter for pulling the player pref, any help would be greatly appreciated

You need to have only one variable for the number of arrows

[fair wadi]

Yeah... I understand its defiently not the best, but it was working and then something changed but I dont remeber changing any code

[leaden ice]

You have 3 different variables and they're going to get out of sync

It's a recipe for disaster

Presumably the arrow keeper should be the source of truth

Get rid of any other variable that tracks arrows

And just always reference the arrow keeper when you need to access the current arrow count

[fair wadi]

Okay that makes sense, thank you!

[fair wadi]

Worked perfectly!

Hi, I want to create an editor script that generate array in editor. But when I use it, it has some error. It works fine when I increase the count, but it leave some 'residue' when I decrease count variable. The child is not destroyed as intended. How can I fix it? Any help is appreciated

i want to add a button on the inspector, but if i extend Editor i cant use getcomponent, is there any ways to keep inspector GUI and this script in one piece?

[leaden solstice]

DestroyImmediate will change your child count and corrupt the loop

Some reverse-for loop or ToList before deletion could work

[worldly hull]

ok i cant believe it must be two classes

[worldly hull]

[CustomEditor(typeof(ContentParent))]
public class ContentButton : Editor
{
    public override void OnInspectorGUI()
    {
        DrawDefaultInspector();

        ContentParent parent = (ContentParent)target;
        if(GUILayout.Button("Build Object"))
        {
            parent.onClick();
        }
    }
}```

as for the script , i put an execute in edit mode there

DONE

[empty elm]

On a build of my game weird things are happening with the delivery/ shop system that doesn't happen in the Unity editor. For example you can continue to buy a stack of items that is already purchased, among other bugs.
What are possible reasons that can cause this (or any ) discrepancy between the editor and the build? That will help me out a lot in where to look for the bug.

[weak pecan]

hi there,

i wanted to make a productivity game where it requires the least amount of work to track your progress.

now, i just found out that unity isnt really capable of automatic startup/ running at background, so im trying to do it with raw code.

question is, im quite lost, as i dont know where to start. can anyone give me some small insights on where should i start?

[rigid island]

did you remove the VC package

[eager fulcrum]

why is my character floating above the tilemap collider?

there is a tiny gap

[rigid island]

not really a code question

you can probably decrease the Default Contact Offset in the Physics tab
(this comes at higher cpu cost)

Ah true, will move the question

advanced GUI coding topics

u see theres two buttons below, is there any ways to allow inspector to track whether objMapper has something in it?

i want to disable the "refresh UI" when objMapper has something, this is only editor mode scripts, so it needs to keep tracking in editor mode

• when objMapper is empty , enable Refresh UI button, disable refresh map UI button

• when its not empty, do the opposite

[CustomEditor(typeof(ContentParent))]
public class ContentButton : Editor
{
    public override void OnInspectorGUI()
    {
        DrawDefaultInspector();

        ContentParent parent = (ContentParent)target;
        
        if(GUILayout.Button("Refresh UI"))
        {
            parent.onClick();
        }
        
        if(GUILayout.Button("Refresh UI with map"))

[storm sleet]

how can i store a static reference of a material? i tried to make a static class and use Resources.Load<Material>() in the static constructor but its not allowed and they advice to use awake, so is there other method i can use? or do i really need to have a monobehaviour for this?

[steady bobcat]

you can use this: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/RuntimeInitializeOnLoadMethodAttribute.html

[storm sleet]

btw this is only for edit mode not for runtime

this is not meant to go for the build, its only for development

[steady bobcat]

then use the editor variant of that attribute, you can find it im sure

Or just make a property/function that will cache the ref on first get

[storm sleet]

i will have a look on that

[mortal needle]

Is this the correct way to calculate a child's world position after rotating the parent x degrees around its Z axis without actually rotating?

parent.transform.TransformPoint(Quaternion.AngleAxis(x, Vector3.forward) * child.localPosition)

[storm sleet]

Asset operations such as asset loading should be avoided in InitializeOnLoad methods

[steady bobcat]

do a lazy load thing then so you load it once still

[maiden fractal]

Looks about right to me. Try it out and see

[molten musk]

i have a fog of war in my game where a black overlay covers the map. id like objects to be able to reveal areas based on some set values including a radius and the arc of the revealing shape. how should i go about this?

[plucky inlet]

Sounds like a custom shader with masking on a black white texture to show/hide.

[warm badger]

back then, when i was using the old input system...while using GetAxis, the rotation of cam used to be smooth..basically the value used to gradually increase and gradually decrease after no input is there...but now when i use the new input and calculating touch.delta, it is not that smooth.. i mean when i lift my touch, that gradual falloff is not there anymore...is there something i'm doing wrong?

[plucky inlet]

the falloff is nothing, that is built in to the input system. You just get the values and have to store and increase/decrease them yourself to the level of smoothness you desire

Simplest would be to store the rawValue and have a lerpedValue that gets smoothed in some loop/update

[molten musk]

how would i implement this

[plucky inlet]

#archived-shaders

[trim schooner]

Fog of war is a common mechanic, they'll be loads of tutorials for doing it already

[plucky inlet]

Even free assets in store already

[trim schooner]

Most likely, yeah !

[latent latch]

the traditional way is just use a texture that you edit the alpha values of

otherwise stencils but I like the texture idea more

[trim schooner]

delete from here too.. and don't crosspost.

[steady bobcat]

got an example of a response?

what class did you create soo far?
If you want to de serialize into a dictionary you want something better like json.net

Hm that should work 🤔

May not be related but use UnityWebRequest
could be off the main thread causing an exception when using the unity api after (and tasks wont print exceptions properly unless using something like UniTask)

[mellow hill]

You could try changing the collection type from a List<T> to an array, the JsonUtility built-in library is very limited and is a reason most people prefer to use NewtonsoftJSON

[swift falcon]

hello

[steady bobcat]

i wonder if it matters if you have the list not be null on creation?

it shouldn't as it says it uses the unity serialization but i cant think of anything else

then must fail at parsing somehow

[plucky inlet]

Did you compare your data class being serialised to the JSON response from server?

Can you try to use your class instead of var?

[steady bobcat]

they put the generic arg it wont matter

[plucky inlet]

Ill test on my side

[steady bobcat]

is this being tested via some mod or in a normal unity project? @swift falcon

[plucky inlet]

your code is working for me

[steady bobcat]

Then probably caused by being loaded via this mod framework

[plucky inlet]

Thats all I did

[fossil obsidian]

guys, as I'm progressing with my game and adding more stuff, there's new inputs, events, etc that are detected via Update(), but now running all the stuff I have in the game in every single frame is starting to be a bad idea, but idk how I would handle these events in a more optimizated way. Could someone tell me how to do it?

[steady bobcat]

FromJson() goes to some internal native function so Id guess how unity looks for types is not able to find this type and thus parsing fails

[plucky inlet]

are you using the new input system with events being called instead of update checking for Input.keys ?

[steady bobcat]

Your fix will be to try to include a better json parser like json.net. Can the mod framework include other .dlls ?

[plucky inlet]

What is your data type when you log it, or is it probably null?

[steady bobcat]

how is your mod code loaded then? surely other managed code can be added alongside it?

Or find some json parser you can include raw with your mod code

[fossil obsidian]

it's very complicated and i couldnt find somewhere that explains it properly, but yea it'd be great anyways. But there's still other things like collision triggers and etc

[plucky inlet]

I am just wondering, isnt newtonsoft already part of unity anyways?

[plucky inlet]

Ah, got you. Its not that complicated, and handling other events is always better layed out on paper before coding. write down your game mechanics and events, that happena nd go from there writing managers and correct loops for data handling

[mellow hill]

No, you can install it via GitHub from their package manager but they have removed it from their package manager I believe, which is bizarre

[steady bobcat]

I think its an optional package but often included in projects now, could work!

[plucky inlet]

Let me check on 6(2023)

[steady bobcat]

its com.unity.nuget.newtonsoft-json

[plucky inlet]

yeh, its just a standard package you can install and ship along

[mellow hill]

LitJSON is another good JSON library if you cannot go with Newtonsoft

Sorry wrong reply

[steady bobcat]

depends what @swift falcon can include or use with this mod.
seeing if newtonsoft json was already in there to use would be best

[mellow hill]

I do a similar thing with my project where I have a .NET web API that connects to a MongoDB back-end but I haven't worked with BepinEx

[plucky inlet]

Can you log your data type you get after the serialisation?

And when you use ToJson I guess your list is empty?

[steady bobcat]

@swift falcon perhaps you can just slap the src for this in the mod. Otherwise see if you can have other dependencies go along with your mod code

https://github.com/MessagePack-CSharp/MessagePack-CSharp
anyone use MessagePack for serialization?

[thick terrace]

yeah, i love it

[still jungle]

just digging around about unity serialization system and thinking that there are better ways to serialize stuff

and that repo looks very good

[junior dock]

Do you mean plastic SCM?

should i just dm you?

[plucky inlet]

Depends on what you need it for. Networking, def. messagepack over other stuff.

[thick terrace]

i have very few complaints about MP in years of using it in games, the only thing that's problematic in unity is it can be fiddly to get the MPC code generator working for unity projects. there's a rosyln source generator now which is supposed to replace it but that doesn't work in my project for mystery reasons 😔

[rigid island]

ye

[junior dock]

ok so i did some stuff lemme dm you it is that alright?

[kind nymph]

ok so i havent done something like parallax in a long time and not surprisingly I've run into some weird behaviour. Basically I'm trying to get my hud to have a parallax effect depending on where the mouse is on the screen (This affects both position and rotation)

What I was expecting to happen:

• HUD to move and rotate based on where the mouse is on the screen
• Stay within the confines of the screen (this works)

What actually happens:

• HUD moves correctly but is very jittery
• HUD rotates incorrectly (the axis are mixed up I think) and also is even more jittery than the movement

the link leads to the code responsible for operating this and also attached is a 10s video of what it currently looks like

[placid summit]

hi does anyone understand conversion to quaternion and back to euler angles? I find it odd that if you convert euler 110,0,0 to quaternion and back you end up with 70,180,180!

[heady iris]

Both of those sets of euler angles describe the same thing

This is why it's perilous to read Euler angles -- you can get surprising results if you try to look at a single axis

[woeful spire]

I believe they describe the same rotation, just with different steps. That's a big issue with Euler Angles, and something that's mitigated with Quaternions.
Generally you don't want to work with Euler unless strictly necessary. Converting back and fourth seems odd too.

[still jungle]

thanks for the feedback, gonna add it to my tools list for serialization then

[placid summit]

actually euler is nice and simple to understand for msot cases I find - only if you hit gimbal loc issues will it be a problem (and most games do not)

anyway seems the inspector does a magic trick to keep euler angles as simple as possible - discussed on forum but hard to follow

[heady iris]

The inspector stores the euler angles you inputted so that it can show them to you later

[placid summit]

it is a rabbit hole - Unity actually stores m_LocalEulerAnglesHint: {x: 0, y: 0, z: 0}

[heady iris]

(rather than converting quaternions back into eulers)

[placid summit]

it is not the same transform.localeulerangles you read

[heady iris]

I never work with Euler angles. I just use the Quaternion methods (e.g. Quaternion.AngleAxis) to construct rotations

[placid summit]

I need to serialize rotation and seems less clean to serialize quaternion - does Unity not serialize euler?

[heady iris]

euler angles are just a Vector3; you can certainly serialize that

One annoying thing about serializing a Quaternion is that the default value is [0,0,0,0] -- it's a struct, after all

this is an invalid quaternion

[woeful spire]

serializing Quaternions shouldn't have to be done unless you're a mathematics major.

[placid summit]

ah Unity itself serializes the qauternion rotation and a euler 'hint'. How odd!

[heady iris]

You probably don't want to edit them directly (:

[lean sail]

well it is also less numbers to serialize

[heady iris]

it'd be like exposing a Matrix4x4 instead of a position, rotation, and scale

[lean sail]

oops meant to reply to the guy above that, that serializing a vector3 is less than quaternion

[wheat spruce]

whats the intended way to deal with the fact that setting a value in the inspector is "volatile" in the sense that it wouldnt take much for that value to get wiped. I've got a class with 8 or so properties, and the safest thing for me is to figure out what value works right in the inspector, then I go and update the code itself to make sure that if I lost the inspectors settings, I wont actually lose anything

[rigid island]

no dms sry. You can just send here np

[latent latch]

version control

or copy paste the meta somewhere

[lean sail]

if the numbers are fine to just assign in code, then i dont see an issue with that. if this were something else, like configuring stats across a bunch of different npcs, then you'd usually use scriptable objects.
in version control you'd easily see if u accidentally changed a value to a scriptable object. if you accidentally changed a component in a scene you most likely wont notice it. if its on a prefab maybe

[wheat spruce]

version control isnt something I've actually looked into with unity

in the past I've only ever used git to commit stuff

[lean sail]

in that case id worry less about the values in inspector, compared to the fact that you could lose your entire project unexpectedly

git is version control, and the best option to use

[wheat spruce]

I'd probably be more worried about what else would be lost in the rare chance that the harddrive fails

I'll look into unity version control

[rigid island]

tbh stick with Git. UVC is kinda horrid

[lean sail]

theres many more ways that u can lose a project instead of the hard drive failing. it could just corrupt, or you could do something weird and a meta file breaks. its a real pita

[thin aurora]

@wheat spruce

[junior dock]

Okay i invited my friend over but how do i connect my unity game with the plastic? please help me!!!

[wheat spruce]

yeah the LFS was something I encountered before but I dont think the restrictions ever came up

[rigid island]

cue meme : Aw shit here we go again..

another confusing moment brought to you by Unity VC ™️

[thin aurora]

Well, read above. Maybe consider using Git instead. I think there's a lot morer support in general when you use Git.

Unity VC is something I don't bother with because Git has existed since forever and I don't see a reason to suggest Unity VC over Git

[wheat spruce]

surely UVC would deal with LFS without any extra effort right?

[lean sail]

id be really curious how many people here can even help with unity VC in the first place, when i explored the options, there was no reason to use anything other than git.

[rigid island]

barely

[wheat spruce]

to whom is this responding

[thin aurora]

Dunno but Git LFS is not exactly hard to set up

[rigid island]

"surely UVC would deal with LFS without any extra effort right?
"

[wheat spruce]

ah

[rigid island]

in GIT all you do is 1 command and its done

[thin aurora]

The only issue might be sizing, in which case I believe Gitlab has more space over Github but I can't confirm that

[lean sail]

you might not even have to worry about large files tbh

[rigid island]

gitlab indeed gives you more than github iirc

[junior dock]

but could you tell me how he could work togheter, cuz we need to do the scripting AND the designing togheter

[wheat spruce]

yeah it never came up, mostly as the projects have never been gigantic

[heady iris]

it is if you don't read the instructions correctly

kablam

[latent latch]

just dont drop all your assets into it

[rigid island]

get on a discord call together, use Github desktop to push and pull changes

[heady iris]

I just self-host a git server and shove everything directly into Git

[wheat spruce]

biggest directory I ended up getting was be included in the .gitignore

[lean sail]

you just download the already made gitignore. dont do anything weird yourself

[heady iris]

The one case where I'm leery about "Just Put It In Git" is my substance painter files

those things are huge

[rigid island]

keep big arts assets separate than VC. so no really need for LFS

[wheat spruce]

yeah thats what I mean

[thin aurora]

I posted a video that explains how to use Git, which is very easy. Do note that regardless of the type of version control you use, you generally should not concurrently work on the same file or asset as it will introduce conflicts due to overwritten changes. Git actively avoids this and will end up requiring you to manually specify the correct version. Try working on separate files/scenes instead.

[heady iris]

currently I just...don't version control those. Uh oh.

[junior dock]

but isnt that kinda hard to do that the whole time 😭 cuz we need to work 160 hours on it toghether

[heady iris]

that's a very specific requirement

[rigid island]

you're still doing the exact same thing with UVC

[junior dock]

ohhhhh

[rigid island]

unity vc is not magic realtime collab

[junior dock]

do you guys have any other program where it is easier to make a game on 😭

[rigid island]

works similiar to git

[junior dock]

togheter

[latent latch]

GitLFS still have problems with large pushes of data... ideally just keep the stuff local and use placeholders if it's large enough

[rigid island]

that is the easiest

[junior dock]

damm 😭

[rigid island]

even easier than that is you both working on the same computer

[thin aurora]

@junior dock Take a look at this video. It explains version control using, hosting your code/repo/game on GitHub through Git (two separate things), and if you're interested explains a GUI application called Github Desktop that allows you to combine the former two very easily with simple visualization.

[rigid island]

this isn't a multiplayer game, its not trivial to connect them(unity apps) together properly without issues @junior dock

[junior dock]

could we also share the same account so that we could work on it?

[rigid island]

no need, just setup the repo as collab

you guys can do the same changes

[junior dock]

alr tysm

[thin aurora]

If you set up a Github repository correctly, you can use two separate accounts as collaborators. You should not use the same account. Just make sure the repository is private and just for the two of you.

[junior dock]

but could this be an option

[thin aurora]

Context needed, there's very little reason to do this unless it's easier to write

Json is very easy, just takes more to write if you end up having to do lots of manual labour

[rigid island]

eww

csv is messy

[thin aurora]

Have you been using JsonUtility or Newtonsoft?

[heady iris]

i'm not sure how a modding framework would have anything to do with parsing json

[thin aurora]

Well there's your problem. Try switching to Newtonsoft

Most likely JsonUtility can't deserialize it

[heady iris]

JsonUtility has some important limitations

note that we can't really help you with modding here

[thin aurora]

You can load dll files. Try loading a .NET Standard 2.0/2.1 compatible version of Newtonsoft

[rigid island]

yeah for one JsonUtility doesnt handle props or dictionary and anything unity cannot serialize

[heady iris]

and this is a great example of why

it creates really weird problems that make no sense in the context of normal game development

[wheat spruce]

nah go and use one of the 1000 different "its no different to json but the dev wanted to try and fix json" json alternatives

[thin aurora]

Ah yeah, Bepinpex is modding.
