[rigid island]

oo beat me to the link

[modern creek]

(F - not D - F is for "fixed point" integers)

"N" if you want commas in your big numbers

[prime crane]

I just need to compare two floats but 2 numbers after ,

[modern creek]

then F2

[prime crane]

Its ok to use in an update ? i need that dont depress the performance

[modern creek]

Debug.LogError(number1.ToString("F2"));
Debug.LogError($"{number1:F2}"); // same same

yes, don't worry about performance

[prime crane]

Thank you !

[modern creek]

(if you have performance issues, this isn't why)

np

[prime crane]

But its for format to string ?
If i would like compare the format "x,xx" of these : "-8,109922E-12" and "-8,10923E-12" ?

Its MathF.Round something ?

[modern creek]

don't compare floating point numbers, they'll (almost never) be equal

if you want to compare them, then yes, you'll need to round them to whatever you define your epsilon to be

[prime crane]

but just the two numbers after ,

Its ok to use mathf round them in update() ?

[modern creek]

"just" the two numbers after the comma will almost never be the same.. What are you trying to do..?

[prime crane]

I have vehicle and i need to know when he stop to rotation (he have a Quaternion.Slerp))
So i compare the old rotation with the new, that works for East, West and South but at the north i have these "-8,109922E-12

[modern creek]

if you are trying to compare 2 floats - this is what you are actually comparing: https://en.wikipedia.org/wiki/IEEE_754

Floats don't have a "just the part after the comma" - they're 32 bits of information that all mean something different

[modern creek]

K, so in your case, you want to round to something that means enough precision (epsilon) for your use case - probably a lot, like 5 degrees or more

truncate or round it to the nearest int and see if it's within 10 of your cardinal directions

[polar marten]

have you looked at https://assetstore.unity.com/packages/tools/physics/vehicle-physics-pro-community-edition-153556 ?

it's free

Runner... are you trying to make an infinite runner?

[prime crane]

No need thx

[polar marten]

okay well it's a good start on your programming journey 🙂

[prime crane]

No its like the manager of Photon Fusion (networking

[polar marten]

got it. you are trying to make a multiplayer driving game?

[prime crane]

I did already , just need to help me for something

[polar marten]

the linked one? looks nice

[prime crane]

Tank you :]

[wintry crescent]

Can someone sanity check me?
This is my code, and this is the debug.log result of the foreach loop, then the debug.log

[wintry crescent]

am I crazy? Like what the hell am I doing wrong

[wintry crescent]

I checked, the values aren't null

I HAVE overridden == operator on the type I'm using as a key, but I've also overriden Equals in the exact same way so it should be fine...?

how is dictionary serialising the key?

[modern creek]

show your overloads and equals() implementation

[modern creek]

can you post code instead of screenshots, this is super hard to read

but in your code snippet above - i can't really tell what your debug.logs are - are you doing this twice? or are those messages with multiple items in the loop?

[knotty sun]

where to you set a value to tutorialSelector?

[modern creek]

well his debug log says "true" right before the error so it seems like that's not the problem

[wintry crescent]

the dictionary contains two values, foreach has 2 debug logs, so there are 4 debug logs from the dictionary, and the final debug.log errors out because the element is "not present"

[hexed pecan]

Yeah what if tutorialselector is null

[knotty sun]

irrelevant, that is not setting a value

[wintry crescent]

I have verified that tutorialSelectors are not null, and the values in the dictionary are also not null

[wintry crescent]

another foreach loop just above this one

[knotty sun]

but you dont set tutorialSelector anywhere in that code

[wintry crescent]

it's a foreach loop irrelevant to the one I'm showing, I made sure it's a valid value

especially since as you can see it's equal to a valid value

as per the equal override i sent

[knotty sun]

assumption and $1 might just buy you a cup of very bad coffee

[knotty sun]

the code you showed does not set tutorialSelector so how can the code that does be irrelevant?

[modern creek]

i mean.. your debug.logs aren't helping you.. I'd probably do something a bit more verbose just so you can make sure:

Debug.Log($"Key:{highlightElement.Key}, Y:{tutorialSelector}"); 

(inside the loop)

[wintry crescent]

this is the entire function:

foreach (var tutorialSelector in tutorialToOpen)
            {
                foreach (var highlightElement in tutorialHighlightElements)
                {
                    Debug.Log(tutorialSelector + " " + highlightElement.Key + " " + highlightElement.Value[0]);
                    Debug.Log(tutorialSelector == highlightElement.Key);
                }
                Debug.Log("highlight element " + tutorialHighlightElements[tutorialSelector]);
                if (tutorialHighlightElements.TryGetValue(tutorialSelector, out var element))
                {
                    tutorialController.Init(
                        tutorial.GetStage(tutorialSelector).data,
                        element
                    );
                }
                else
                {
                    tutorialController.Init(
                        tutorialConfiguration.GetDataForStage(tutorialSelector),
                        null
                    );
                }
            }
            tutorialToOpen.Clear();

[wintry crescent]

with you debug as the only debug inside the loop, here's the result

debugged hashcodes instead, we're on the right track! now... why?

[modern creek]

are your keys monobehaviours?

[wintry crescent]

why are my hashcodes different? the objects are the same

no

[wintry crescent]

pure c# class

[modern creek]

well i mean... that's your problem, no? equality for keys doesn't mean that item exists in your dictionary

[wintry crescent]

item exists in dictionary I checked, the key is valid, the issue is why the hashcodes are different when all values on the object are the same

[modern creek]

the item doesn't exist in the dictionary, but rather, there is an item in your dictionary which is "equal" to the item you're checking

but it's a separate item in memory

[wintry crescent]

ah yes that is true

how do I fix it

[modern creek]

say you have a dictionary of .. i dunno, members of your family. And you've decided that anyone with the same name IS the same - that doesn't mean that some other dude with the same name is in your family, it just means he's "equal"

[wintry crescent]

override GetHashCode?

[modern creek]

no - find the element in your dictionary you care about and then operate on that element

lemme look at your code again

[wintry crescent]

oooh would making it a struct fix it perhaps?

[modern creek]

no

you're thinking about it wrong

you have a dictionary of.. what.. tutorials? and you're trying to find the right tutorial based on something the user's done?

so look up the tutorial you care about (by key) and do that thing

lemme write some pseudocode how i'd do this

[wintry crescent]

no, I have a tutorial selector class I made

it's pretty much a c# class with 2 strings and a type variable, that I can easily assign in the inspector

[modern creek]

Dictionary<int, Tutorial> TutorialsDictionary = new();
int tutorialKey; // or an enum, or your own compareable that you linked above
Tutorial newTutorial = new() { ... };

TutorialsDictionary.Add(newTutorial);

... now the user wants to see a tutorial ...

public void ShowTutorial(int which)
{
  Tutorial showThisTutorial = TutorialsDictionary[which]; // or use tryget with error handling
  showThisTutorial.ShowTheTutorial();
}

you... should just have one dictionary, and look up the item you care about in that dictionary...

[wintry crescent]

that's de facto what I'm doing, it's just that instead of an int key I have a TutorialSelector key

[modern creek]

i don't really understand the way you've done it? even with the custom key (which seems like overkill? just use an enum?)

[wintry crescent]

explaining why I have removed the enum option would make us be here all day 🙃

I really would like to just make my custom key work please

how can I achieve that?

I have a single string inside the custom key that is pretty much the entire thing

[modern creek]

well.. i mean, you have a fundamental misunderstanding of how pointers/memory/comparison works so .. i was just trying to maybe simplify it

[wintry crescent]

I don't think I do... there might be a miscommunication happening though

[steady bobcat]

classes will reference compare by default unless you override it. You can also supply a custom comparison thingy for dictionary instances.

[modern creek]

equality means two different things - are they the same values, or are they the same items in memory.. your code isn't working because you're trying to point to an item in memory that is value-equal but not the same item so it doesn't exist in your dictionary

[wintry crescent]

are you telling me that the dictionary is doing a pointer comparison? that makes no sense at all

it's probably doing a hashcode comparison

and I have different hashcodes on otherwise equal objects so it'd make sense

[modern creek]

but they aren't the same object

[wintry crescent]

but from the perspective of my code they might as well be

the TutorialSelector is meant as a "pointer" to a class that defines a particular tutorial

[modern creek]

Dictionary<MyKeyType, MyObject> myDict = new();
MyKeyType one = new(); 
MyKeyType two = new(); 

myDict.Add(one);
foreach (var kvp in myDict)
{
  if (kvp.Key == two) // found it! no.. actually, you didn't, you just found an object that looks like it...
}
myDict[two].DoSomething(); // key not found exception

this is what you're doing, fundamentally

right?

your problem is that you've overridden equality to mean something it's not - you're sorta treating a class like a struct

just changing the class to a struct won't fix it

"two" is equal to one (because the values in two are the same as the values in one - because you've overridden equals and == properly) but that doesn't mean myDict contains two.. it contains an element (one) that looks like two but isn't

trying to "get" two from myDict won't work because mydict doesn't contain it

[wintry crescent]

ok - so how do I make it work? I need the key to remain as my key type

[modern creek]

if you want to use the object one in myDict that looks like two... then do so:

Dictionary<MyKeyType, MyObject> myDict = new();
MyKeyType one = new(); 
MyKeyType two = new(); 

myDict.Add(one);
MyObject theRealObject;
foreach (var kvp in myDict)
{
  if (kvp.Key == two) theRealObject = kvp.Value;
}
theRealObject.DoSomething(); // $$

[wintry crescent]

well that defeats the whole point of using a dictionary, if I have to loop through the whole thing anyway

[modern creek]

agreed? 😛 like I said.. I'm not sure you're understanding what's going on under the hood.. you say you do but you're kinda jumping through 3 steps to do 1 thing

[steady bobcat]

I believe if you have a custom EqualityComparer for the class it will work for many objects to work the same

i had an issue once where i wanted reference comparison so i had to override it for a dictionary instance (which is possible)

[wintry crescent]

why can't I just override GetHashCode?

I'm pretty sure that'd work

[steady bobcat]

Dont ask me ask microsoft?
go read: https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.dictionary-2?view=net-9.0#remarks

[wintry crescent]

actually lemmie try with that override it might be just that simple

[modern creek]

if the key really is an immutable type then you could make it a struct and it'll work, but you seemed to imply that you had other functionality?

[wintry crescent]

it sure is that simple lmao. it works now

[wintry crescent]

I do, but I guess it doesn't really have to be a class

actually no wait

it has to be a class

because it's abstract

[modern creek]

i mean.. the thing is, what you have might "work" but i suspect you're creating downstream problems for yourself (memory leaks because you aren't pointing to the right object), etc

[wintry crescent]

and also structs don't have default parameters which is making me mad because I have some editor-only stuff that is really annoying in a struct

[modern creek]

if you need to have speed on your dictionary for lookups - then use the right data type and use a primitive for the key, or read rob's article

you mentioned that you had some strings you wanted to see in the editor so it sounds like it's a monobehaviour?

[fallow quartz]

I have an object that automatically places itself parallel to the terrain in the point it spawns. Now I want the player to get impulse in perpendicular to the direction of the object (Just like a bouncer) but i cant get that to work

[steady bobcat]

why not have a unique int id for each tutorial stage so you dont have to struggle soo much?

[wintry crescent]

it's not a monobehaviour, it's just a type that gets referenced in a monobehaviour

[modern creek]

ah

[wintry crescent]

because the whole point of that selector is to have a nice selection for all the tutorials without having to mess with an int
it's pretty cool check it out

[modern creek]

then yes gethashcode should do the trick - but just be aware you need to know what you're doing because you've got two items in memory but you're only looking for one?

[steady bobcat]

im good 😆

[wintry crescent]

I define classes that derive from tutorial stage, and all the defined classes appear in all my selectors like this

simply defining a class automatically adds it as an option everywhere where a tutorial reference is needed

[steady bobcat]

Its a list of System.Type?

[wintry crescent]

yea

but it doesn't store a list, it just stores the serialized type itself

I create it like a normal variable and it just provides me an always up to date list like this in the inspector

I had a different problem where I wanted to create an instance of the selected type somewhere

but I pretty much had to do reflection 🙃 couldn't figure out a better way

[steady bobcat]

Activator.CreateInstance() can make an new instance but may require a parameterless constructor

[wintry crescent]

Waaait what? never heard of this

I can certainly figure out a parameterless constructor

[steady bobcat]

oh no seems it supports args too. go have a looky

[wintry crescent]

o damn so cool, thanks!!

that's so cool I was so scared I had to have random reflection in my code

phew

[steady bobcat]

not able to use scriptable objects to manager it better?

[wintry crescent]

whatever it is, is better than this line XD

[wintry crescent]

if I tried to explain it we'd be here all day 🙃 I'm using scriptableObjects where I can

[steady bobcat]

Oof yea that isnt pretty 😐

np hopefully this makes it a tad easier now

[wintry crescent]

it's beautiful <3 thanks again!

[steady bobcat]

np i once did some stuff like this years ago and discovered it then

[heady iris]

Of course, this is still reflection -- it's just hidden from you 😉

[thin aurora]

You should really look into using the generic type overload for CreateInstance and possibly create it from data

Your generic type can have a rule that the type must support new(). Right now you not only have an implicit type defined, you also indirectly require it to have a parameterless constructor

[wintry crescent]

shhhh, if you can't see it it doesn't exist ;)

[thin aurora]

Also, the reflection obviously

[wintry crescent]

wdym generic type overload for createinstance?

you mean like something that derives from Type...?

I feel like I'm misunderstanding something

although it would be cool

[thin aurora]

There is an overload that allows you to specify a generic type parameter rather than a Type parameter like you have now

[steady bobcat]

Doing it via a generic function can also work but i think restricts you to new() only?

public T MakeNew<T>() where T : new()
{
    return new T();
}

[thin aurora]

Basically in your TutorialStage class you'd have a method abstract TutorialStage CreateInstance(); which all your derived types implement

[wintry crescent]

generic function doesn't work for me since it needs to be assignable through the inspector

[thin aurora]

Or at least, it doesn't seem like this is the main type you use

I have no idea what data.stage can have in this case

[wintry crescent]

data is a scriptableobject with some strings and a reference to the class (through the tutorialselector), it has no business making the instances by itself

[thin aurora]

Oh, it's an SO? Then perhaps it's not as suitable here

It's probably possible, but in this case the work involved is not worth it

[wintry crescent]

yea but I can't call it from a Type variable, can I

[heady iris]

there's not enough information there, yeah

[wintry crescent]

TutorialStage isn't a SO

data is something else

[heady iris]

you just have a Type object

[thin aurora]

The type must be known at compile time, that is the whole thing

I don't think you can do that here

Like I said it can be done, but the work involved is not worth it due to the complexity

[wintry crescent]

I mean technically I could make it "known at compile time" enough but yeah that'd be too much work for nothing

[heady iris]

Just pinky-swear to not mess up (:

sometimes the type system needs a little help from the outside

[wintry crescent]

sure does, thank god I can do the preserve attribute assembly-wide xd

this isn't the first time I'm on this ride lmao

[fallow quartz]

Is there any way to apply a force to a character controller with a direction? Having all of the axis custom

[vagrant blade]

Force is a direction

Get the direction you want, apply it to the CC in the .Move function.

[leaden ice]

CharacterController doesn't automatically simulate "forces". You just tell it exactly where to move.

if you want to simulate forces you need to build a system for forces and velocity etc yourself.

[fallow quartz]

    private void ApplyImpulse(PlayerController playerController)
    {
        Quaternion rotation = transform.rotation;

        // Calcular las direcciones basadas en la rotación
        Vector3 forwardDirection = rotation * Vector3.forward; // Dirección hacia adelante (eje Z)
        Vector3 upDirection = rotation * Vector3.up;           // Dirección hacia arriba (eje Y)
        Vector3 rightDirection = rotation * Vector3.right;     // Dirección hacia la derecha (eje X)

        // Combinar las direcciones (puedes ajustar los pesos según tus necesidades)
        float forwardWeight = 20.0f;  // Peso del impulso hacia adelante
        float upWeight = 10f;       // Peso del impulso hacia arriba
        float rightWeight = 20f;    // Peso del impulso hacia la derecha

        Vector3 impulseDirection =
            (forwardDirection * forwardWeight) +
            (upDirection * upWeight) +
            (rightDirection * rightWeight);

        // Normalizar la dirección combinada para que tenga magnitud 1
        impulseDirection = impulseDirection.normalized;

        // Aplicar el impulso calculado al jugador
        playerController.GetComponent<CharacterController>().Move(_impulseForce * impulseDirection);
    }```

like this when i execute the method the player just tps

[leaden ice]

yeah i mean

This function is called "ApplyImpulse" but that's exactly what it would actually do

just teleport

If you want velocity and momentum you need to simulate that yourself

store those things in variables

and apply the velocity as motion each frame

[fallow quartz]

I want to make it behave like a bouncer

[leaden ice]

idk what a "bouncer" is other than the guy who kicks you out of a nightclub

[fallow quartz]

this, but for example if its in a diagonal spot

[leaden ice]

That's a trampoline

[fallow quartz]

it will bounce u off the direction is looking at

[leaden ice]

anyway your player object would need to keep track of its own velocity and simulate momentum for you to have a mechanic like this

right now it seems like you have a very simple movement script that just directly moves it

To be honest if you want external forces to affect your character in this way, CharacterController is not necessarily the right approach.

A Rigidbody-based controller may be more suitable for you

otherwise you need to simulate velocity and forces yourself

[fallow quartz]

I have a more complex script regarding the character controller movement

[leaden ice]

this script is just directly currying the input into a movement

there's a veriable called "velocity" but you're not actually storing velocity frame-to-frame

you're just directly overwriting it from the input each frame

So again, you'll need a more sophisticated system if you want external forces and momentum

[fallow quartz]

ggs

[ivory smelt]

we tried man

But with rigidbody u gotta code almost any physics interaction from 0

mostly we were having trouble with slopes

[leaden ice]

I feel like you have that exactly opposite

Rigidbody gives you most physics interactions for free (movement/velocity/momentum, collisions, bouncing, friction etc)

CC is just basic movement with collisions and that's it

no momentum

no impulses

no forces

nothing

[fallow quartz]

 public IEnumerator Dash()
    {
        _isDashing = true;
        _isDashOnCooldown = true;

        _trail.emitting = true;
        float originalFov = _camera.fieldOfView;

        Vector3 dashDirection = transform.right * _move.x + transform.forward * _move.y;

        if (dashDirection == Vector3.zero) //default direction when no input
        {
            dashDirection = transform.forward;
        }

        float elapsedTime = 0f;
        while (elapsedTime < _dashDuration)
        {
            float progress = elapsedTime / _dashDuration;

            float curveValue = _dashFovCurve.Evaluate(progress);
            _camera.fieldOfView = originalFov + (curveValue * _dashFovChange);

            _characterController.Move(dashDirection * _dashForce * Time.deltaTime / _dashDuration);

            elapsedTime += Time.deltaTime;
            yield return null;
        }

        _trail.emitting = false;
        _camera.fieldOfView = originalFov;

        _isDashing = false;
        yield return new WaitForSeconds(_dashCooldown + _dashDuration); //avoid counting the performing time as cooldown
        _isDashOnCooldown = false;
    }

but for example this dash works

[leaden ice]

yeah... and it's all done completely manually

[fallow quartz]

If i change the dash direction for the direction of my object, shouldnt it work the bounce thing?

[leaden ice]

I mean if you want to model it as a dash, sure I guess

[fallow quartz]

    public IEnumerator Bounce(Vector3 impulseDirection)
    {
        _trail.emitting = true;
        float originalFov = _camera.fieldOfView;

        float elapsedTime = 0f;
        while (elapsedTime < _dashDuration)
        {
            float progress = elapsedTime / _dashDuration;

            float curveValue = _dashFovCurve.Evaluate(progress);
            _camera.fieldOfView = originalFov + (curveValue * _dashFovChange);

            _characterController.Move(impulseDirection * Time.deltaTime / _dashDuration);

            elapsedTime += Time.deltaTime;
            yield return null;
        }
    }

is not working

[ivory smelt]

for the game we are making it was the most useful solution, CC gives IsGrounded (wich tb fair is pretty ez to do also with rb), slope management, and controlled movement

maybe its time to give it another thought tho

[leaden ice]

yeah because your other one has the _isDashing variable that disables the normal movement

siunce you're not disabling the normal movement here, it's not gonna work

[fallow quartz]

wdym? In the bounce method isdashing is not getting true

[fallow quartz]

so it should work fine right?

[fossil blaze]

public Vector3 GetNextPlacementPosition()
        {
            Collider shelfCollider = GetComponent<Collider>();
            if (shelfCollider == null || maxItems <= 0)
            {
                return Vector3.zero;
            }
            
            float shelfLength = shelfCollider.bounds.size.x;
            Vector3 placementAxis = transform.right.normalized;
            
            if (placementAxis.x < 0)
            {
                placementAxis = -placementAxis;
            }
            
            Vector3 leftEdge = shelfCollider.bounds.min + placementAxis * (shelfLength / (2 * maxItems));
            float spacing = shelfLength / maxItems;
            Vector3 nextPosition = leftEdge + placementAxis * (spacing * placedItems.Count);
            
            nextPosition.y = startingPosition.position.y;
            nextPosition.z = startingPosition.position.z;

            return nextPosition;
        }```

Why is it that when the rack is rotated by Y, the goods are placed one after the other?

[leaden ice]

your code seems to assume everything is laid out along the x axis

pretty explicitly

[fossil blaze]

how to fix it?

[leaden ice]

rewrite it to work in some object's local coordinate space or using a direction vector as a parameter that serves as the layout direction

something like that

[fossil blaze]

Oh, I can't figure it out

[indigo tree]

Here is some math I did. This would work given the starting point and the end point :)

I haven't tested this extensively but you get the idea

[fallow quartz]

Is it possible to add collision to a particle system? And it can be precise?

[latent latch]

yes and somewhat

[leaden ice]

"collision" is vague

what kind of interaction are you looking for

[fallow quartz]

each time a particle touches a collider from a gameobject

collisionenter triggers

[leaden ice]

Read this stuff:
https://docs.unity3d.com/Manual/particle-physics.html

[modern creek]

Are destroyed game objects always disabled? I have a weird bug that I can't chase down.. I have a game object which is null which is (somehow?) still catching C# events and unity has having a fit

I can't seem to chase down this bug

[heady iris]

C# events have nothing to do with Unity at all

[modern creek]

right so .. what I mean is.. i have this:

[leaden ice]

The GameObject being disabled or not has no bearing on C# events on components attached to it

        {
            InterfaceManager.SelectedEntityChanged += OnSelectedEntityChanged;
            InterfaceManager.CommanderSelectEntity += OnSelectedEntityChanged;
            GameManager.EntityHpChanged += OnEntityHpChanged;
        }

        private void OnDisable()
        {
            InterfaceManager.SelectedEntityChanged -= OnSelectedEntityChanged;
            InterfaceManager.CommanderSelectEntity -= OnSelected;
            GameManager.EntityHpChanged -= OnEntityHpChanged;
        }

and I have an object which "doesn't exist" in unity that's getting some of these events

[heady iris]

You can check the timing of OnDisable vs. the unwanted event invocations

I don't recall exactly when that runs after destroying an object

[leaden ice]

You're unsubbing a different method than you are subbing

[heady iris]

whoops

[modern creek]

asldkfjasldfkj mashes face on keyboard

add it to the tab, PB, thx

wait!

no

i just mispasted

(i was trimming out the code)

[leaden ice]

Which event is the problematic one?

[modern creek]

somehow this entity renderer (a monobehaviour) is catching an event when the MB is ... null, so it's not being unsubscribed properly in ondisable

OnSelectedEntityChanged

[leaden ice]

But which delegate is calling it

SelectedEntityChanged or CommanderSelectEntity?

[modern creek]

SelectedEntityChanged

Lemme see if it's maybe related to just the commander

[leaden ice]

When I get into the weeds with this kind of thing I find it helpful to log the listener's instance id:

• When you subscribe the listener
• When you unsubscribe the listener
• When the listener is invoked

[modern creek]

basically I have some... nonexistent MB that's catching this event and trying to turn off the highlight.. but obviously it fails because the MB has been long since deleted

yeah - that was my approach, and I can see that the GO that's calling this is clearly the wrong one, but ... I don't know how it exists (unity should have disabled it).. I'll show you, sec.. lemme add some logging

what's the instance id btw? that's on GO?

[leaden ice]

GetInstanceID() MonoBehaviour has it

[modern creek]

thx

[leaden ice]

(there's one for the GO too but we're really interested in the MB here)

[modern creek]

K so we'll look at "Turner" - level 1 init looks like this (and works properly):

when i go to level 2 - level 1 behaviours and renderers are destroyed via my own DestroyAllChildren (which iterates a GO and destroys the children)

level 2 init

looks correct to me so far - turner 4630606 is created and then destroyed

then we create a new turner - 4701712

lemme throw a breakpoint on it and step in

not sure what's going on 😐 but it all looks good on the surface

[leaden ice]

ok where's the part where the event is invoked and the listener is running on a destroyed thing?

[modern creek]

when i click on a UI element, it emits the selected unit changed event - which gets caught by a GO that doesn't exist

gonna see if i can see the instance id

(have to run for a meeting in 7 minutes though)

mouse panel renderer 3 - like so

[leaden ice]

Yeah print the instance id in the listener. I would love to see a series of events like this in the logs:

• OnEnable ran for object 5
• OnDisable ran for object 5
• Listener invoked on object 5

[modern creek]

which I have to init by linking it to the entity in question:

hm... it seems like GetInstanceID() is NRE'ing in here as well

i might need to memoize it

[leaden ice]

yeah it would fail after the object is destroyed

[modern creek]

well gotta run for a stupid standup.. will continue after and see what I can find.. thanks for the eyeballs

think i found it

there are 5 (not 4) mice - they all inherit from EntityRenderer

but i don't call the base ondisable on the overrides

(thought it would do it automatically)

note - ondisable doesn't call base.ondisable

[leaden ice]

yeah that'll do it

make the base one virtual

and you'll get a warning about method hiding if you don't explicitly override it and while you're doing that you'll probably remember to call the base?

[heady iris]

the base will need to be protected, not private

I wish there was a nice way to say "this method MUST invoke the base class's method"

hmm https://stackoverflow.com/questions/37966219/visual-studio-warning-if-base-method-is-not-called

[quartz folio]

Typically you'd have to re-declare it as an additional abstract/virtual method

though I too find that ugly 😄 if there was a jetbrains annotation attribute I'd probably start using it lol

[leaden ice]

Yeah this is the C# way to do it...

    class Parent {

        private void DoSomething() {
            // Do base things here

            // Then call the child behavior
            DoAfter();
        }
        
        protected virtual void DoAfter() { 
           // Do nothing by default
        } 
    }

    class Child : Parent {
        protected override void DoAfter() {
            
        }

        // This would be an error
        protected override void DoSomething() {
            
        }

        // This would, sadly, only be a warning about symbol hiding
        protected void DoSomething() {}
    }
}```

[heady iris]

I've done some program analysis before, but I've never touched Roslyn analyzers

[heady iris]

I did that so that I could run some setup code, then the virtual method, and then some teardown code

(mostly just profile markers right now)

[modern creek]

Yeah so @leaden ice @heady iris that was it, thx for the help. I think I originally set OnDisable up (in the parent) as simply virtual (without making it protected), but I forgot to follow up and implement it properly (protected virtual with overrides on the children that call base.OnDisable). Obviously the random c# object was floating around because it (properly) detected that it was still subscribed to an event.. for which the MB was long ago deleted

Fixed now! tyty

[modern creek]

warning about symbol hiding is sufficient - TWAE for life (throws up gang signs)

even a "message" about symbol hiding is fine by me

[heady iris]

My headache is that I had an abstract method that I switched out for a virtual one

I'm pretty sure I still have a few dangling instances that don't call the base method

[modern creek]

heh

i do it a lot for properties for my abstract parent classes

it makes the children really small since.. the only thing they care about is "what's different"

even my list of DieTypes could probably be removed from the child

vestigal scope appendix

[obsidian anchor]

Having a bit of an issue with a bit of code on my character controller script for a university course. The error report instates that "All implictly-typed variables must initialized."

For reference, here's the script that was given in the canvas module:

[somber nacelle]

compare what you have with what is shown in the example

[obsidian anchor]

Then, this occurs. I copied the exact code like it was referenced in the script. And, it still keeps giving me initialized errors:

[quick token]

:vector3 is more of a comment than actual code

[somber nacelle]

that :Vector3 is not actually typed text, it is just a hint from the IDE to show what the type of the variable is. you do not include that.
you should also start with beginner c# courses (like the ones pinned in #💻┃code-beginner ) if you think that is valid syntax for c#

[obsidian anchor]

Ah, so it can be removed?

[somber nacelle]

not just can be removed, but must be removed because it isn't valid syntax

[obsidian anchor]

Thanks for the help! That solved it! ^^

[indigo drift]

I have a script that needs to read some text from a text file. There are no errors in Unity, but when I actually build my game I get this error, how do I solve this??

(Blacked out part is part of the file directory, it has my name on it)

[quartz folio]

Check if the file exists before trying to read from that location

[leaden ice]

Well you seem to be trying to read a file from the Assets folder, which no longer exists when you make a build

If you want to copy files over verbatim to read with System.IO, you need to use Streaming Assets

[quartz folio]

well, it still exists locally, but it won't on anyone else's machine. It's not a sensible place to try to read from at runtime.

[leaden ice]

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

[modern creek]

windowskey+alt+s, drag a box, ctrl+v right in discord.. don't take a photo of your screen. 🙂

[indigo drift]

Alright, currently it reads from
Application.Datapath + “/Text Files/“ + fileName

Do I just need to change the directory?

[leaden ice]

No, you need to use Streaming Assets instead

Put the files inside the StreamingAssets folder and use Application.streamingAssetsPath

[indigo drift]

Ohhh now I understand thank you

[modern creek]

and also don't use hard coded directory separators in your game.. might work fine on your machine but will break on phones/macs/etc - use directory separator

[leaden ice]

Use Path.Combine

[modern creek]

or that

[indigo drift]

Alrighty I’ll change it thanks guys

[stark sun]

can someone take a look

[jade belfry]

Hi, not sure if anyone here is familiar with the whole imput system, but we have a LOT of worldspace canvas with each their own Graphics Raycaster.

Is there a reason EventSystem.Update / EventSystem.current.RaycastAll is THIS expensive??
Why does it check every single rect in every single canvas? Is there any ways for me to override the GraphicsRaycaster and implement something smarter?

Same question with the XRBaseInteractable. How come is "ProcessInteractionStrength" called every frame for every object?

[dawn mauve]

@low root Did you get the webcam based eye tracking working? Did you end up using openCV or unity sentis?

[low root]

We did actually get webcam tracking working with openCV

We the bought a package to upgrade the detection and I was informed that my team member basically has it working

I would send pics but they have my team members face in it

https://assetstore.unity.com/packages/tools/integration/dlib-facelandmark-detector-64314?aid=1011l4ehR

The jam ends in around 2 weeks so hopefully we have a game I can send here by then

Thanks for the support :)

[dawn mauve]

No prob. Yea was just curious. I'm working on something kinda similar - a webcam based avatar controller. Its been... Interesting.

[low root]

Oh cool!

Our team is solely focus on blinking for this weird game lol

I’ll send the game here once it’s done

[dawn mauve]

👍

[warm badger]

I have made something that would bring one of my UI button wherever on screen I touch (touch screen), but the problem is, the position of the UI, but is not pressed, I have to press it again which I don't want... Any way to fix that?

[indigo tree]

Sorry, can you rephrase this? I don’t understand.

[warm badger]

Actually as you can see in the script, Whenever I touch on the screen, I have a button that is positioned accrding to the position of the touch. Now the button is repositioned in the under the touch, but the button is not clicked, I have to put off my finger and then again I have to touch on that button to register a click on it, To sum up, it doesn't get clicked when its position is changed...

[rigid island]

those are two different events

couldn't you just call the function in the button after you assigned position?

[indigo tree]

Uss or UGUI?

[warm badger]

yeah, i think this should work, thanks, I'll try it now

[warm badger]

UGUI

[warm badger]

but isn't there any way around it, i have seen dynamic floating on screen joystick that relocated wherever player touches, how do they do it then?

[rigid island]

I know that Unity is doing everything through Event System, I'm no expert but I don't think I've seen a way to manually call a click on the EventSystem / Input Module, maybe I just haven't seen it yet

EventSystem iirc register a click on something that blocks the raycast when you do the press

[indigo drift]

I'm using Streaming Assets and it does work, but it makes the assets public, is there something else I can do that won't make it an easily accessible folder?

[errant flame]

I have a [WriteOnly] public NativeParallelMultiHashMap<int, int>.ParallelWriter PointWriter;

inside my paralel job and the definition of the pointWriter is

        NativeParallelMultiHashMap<int, int> pointResult = new(1, Allocator.TempJob);
        NativeParallelMultiHashMap<int, int>.ParallelWriter pointWriter = pointResult.AsParallelWriter();

It says size exceed error but i only do

      PointWriter.Add(index, 0);

In execute so the definition size is the key size or the max value of the key holds ?

Or its already creaing the bucket and when i try to write add its exceed to limit ? so do i have replace the value ?

[soft nymph]

What is the common pattern for storing reusable one off utility functions. E.g. I need to write code the runs a blast effect

[hexed pecan]

I usually put utility functions in a static class. But a "blast effect" doesn't sound like a utility function

Well, I guess you can think of it as one

[hexed pecan]

You can make a singleton or a static class that holds methods for spawning all kinds of effects

[errant flame]

how can i return an array of KVP <int, list<T>> of this

            NativeParallelMultiHashMap<int, NetworkTileBurstData> results = new(allCombinations.Count * 15, Allocator.TempJob);

I want to find out how many values each key holds and loop through these values

[plucky inlet]

isnt this what you should use then? https://docs.unity3d.com/Packages/com.unity.collections@2.5/api/Unity.Collections.NativeParallelMultiHashMap-2.html#Unity_Collections_NativeParallelMultiHashMap_2_CountValuesForKey__0_

[errant flame]

exaclty what was i looking for thanks 😄

[lost rivet]

Ok so whats the best way to go about serializing monobehaviors?
Do i just create another class for every monobehavior and serialize that, or is there any way around this?

[hexed pecan]

https://docs.unity3d.com/2020.1/Documentation/Manual/JSONSerialization.html
JsonUtility can serialize a mono with ToJson and it can deserialize with FromJsonOverwrite

You need to have the component before deserializing into it

[lost rivet]

Huh ive seen people say you couldnt do it

[hexed pecan]

I recently thought so too...

@lost rivet Give it a go and let us know?

[wheat spruce]

On the topic of serializing, I've got a handful of pretty simple values that I'd like to persist as save data

string PlayerName;
int CoinsCollected;
int HealthUpgrade;
int SpeedUpgrade;```What's a fairly straight forward way to do something like that?

[hexed pecan]

Toss them in a struct or a class and use JsonUtility
You can also use Json.NET but JsonUtility works fine here

[wheat spruce]

Sounds simple enough! So once I call ToJson how do I get that to be saved in the right location?

[lost rivet]

I suppose ill try, never did a savesystem in unity before

[tired elk]

Create a file at desired location and write the string into it. https://learn.microsoft.com/en-us/dotnet/standard/io/how-to-write-text-to-a-file

[lost rivet]

Ugh can i just serialize the entire scene and be done with it?

[latent latch]

that'll be unity 9

or some 3rd party asset released around at 7 ;p

[lost rivet]

Idk surely i am missing something

I think i need a way to serialize gameobjects...

[latent latch]

well, you can save transform values, and remember prefabs are simply an ID

[lost rivet]

But changes happened to the object...

[latent latch]

needs to be value types then

[wheat spruce]

Unity[i + 1]

[lost rivet]

Thing is i dont even know what components my gameobject will have when i am serializing it

[latent latch]

mostly just a transform if you think about it

if for some reason you've made this collection of gameobjects that isn't a prefab, then you need to create some load manager that you tell it to structure it the previous way

[lost rivet]

Nit sure what you mean

[vestal arch]

you could GetComponents<Component>()

[fallow quartz]

Is there any way to make rain unity in a big large area without wasting a lot of resources?

[vestal arch]

can you elaborate on what exactly the rain is/does

[fallow quartz]

nothing, is just visually, the effect is handled in other way

[vestal arch]

you could just make it local to the player then

[latent latch]

Probably best to give me an example of what you're saving, but before you do take alook at this object and tell me if it's structured different to any prefab by components

[vestal arch]

enabled/disabled based on position

[fallow quartz]

you mean a transform on top of the player?

[vestal arch]

yeah

not sure if that's a good/common solution, but you wouldn't have to create rain for the entire area

[fallow quartz]

yeah but that has a problem, when u move u can notice is following u + particles spawn and if u get a speed boost its even getting more obv

[vestal arch]

just make it not follow you exactly then

[latent latch]

mostly structs, and like I've mentioned that prefabs are simply an ID which can be included in the struct to show belonging so the next time you instantiated an instance you know where those values go

[vestal arch]

if it's tilable you can just make like, an area around the player (not a child of the player) and then move the tiles based on the position of the player

[fallow quartz]

its on 3d

[vestal arch]

what i suggested would work in 3d

[west lotus]

This is how you do rain snow etc https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@11.0/manual/Block-TileWarpPositions.html

[daring cove]

Hey,

How to scale a rectangle to fit around a 3D game object in a fashion that it highlights it?

This is what I have so far.

highlightedGameObject is the game object to highlight with the rectangle.
rectangle is a game object that has an image for the rectangle.

Vector3 worldPosition = highlightedGameObject.transform.position;
MeshFilter meshFilter = highlightedGameObject.GetComponent<MeshFilter>();

// Get bounds and scale to highlightedGameObject's scale
Vector3 max = new Vector3(
  meshFilter.mesh.bounds.max.x * meshFilter.transform.lossyScale.x,
  meshFilter.mesh.bounds.max.y * meshFilter.transform.lossyScale.y,
  meshFilter.mesh.bounds.max.z * meshFilter.transform.lossyScale.z
);
Vector3 min = new Vector3(
  meshFilter.mesh.bounds.min.x * meshFilter.transform.lossyScale.x,
  meshFilter.mesh.bounds.min.y * meshFilter.transform.lossyScale.y,
  meshFilter.mesh.bounds.min.z * meshFilter.transform.lossyScale.z
);

// Get position of highlightedGameObject in screen space.
Vector3 screenPosition = Camera.main.WorldToScreenPoint(worldPosition);
screenPosition.z = 0f;

// Calculate bounds in screen space
// screenMin = TOP LEFT
// screenMax = BOTTOM RIGHT
Vector3 screenMin = Camera.main.WorldToScreenPoint(worldPosition + min);
Vector3 screenMax = Camera.main.WorldToScreenPoint(worldPosition + max);

// Calculate size for the rectangle 
Vector3 screenSize = new Vector3(
  Mathf.Abs((screenMax - screenMin).x),
  Mathf.Abs((screenMax - screenMin).y),
  1f
);

// move rectangle over the highlightedGameObject in screen space
rectangle.transform.position = screenPosition;
rectangle.transform.localScale = screenSize;

[lost rivet]

Sry im back, my point is that the object can mutate a lot from the time it is instantiated

So idk, i dont see how keeping a reference to its prefab would help at all

[latent latch]

if it's a prefab that you're only mutating known value types and not instantiating say components then it's as simple as mapping where those values go from a load method

if for reason you are creating multiple new gameobjects and components and say want to serialize a whole new prefab at runtime, then that does get a bit more complicated

[lost rivet]

If i adding and removing components?

[latent latch]

There's a Json Newtonsoft package that's just a better JsonUtility and it does help serialize types that it cannot do

basically does a bunch of reflection to find the required object types

also serializes data structs that Unity cannot do like dictionaries

but most of the time I don't need it cause I'm not creating anything unique that I need to serialize at runtime

[lost rivet]

Fair enough

[latent latch]

"Only plain classes and structures are supported; classes derived from UnityEngine.Object (such as MonoBehaviour or ScriptableObject) are not. Note that classes derived from MonoBehaviour or ScriptableObject can be used with JsonUtility.FromJsonOverwrite as an alternative."

But again, it's worth knowing that prefabs and scriptable objects can be identified as an ID

as they do not change between runtimes, only the values that may have mutated

Meaning, if you make a PrefabManager, you can make a lookup table and ID these assets as a KVP

and similarly, components can be identified as an ID too (strings too), or just do it via reflection with Newtonsoft

Newtonsoft can also get out of control pretty quickly if you're serializing larger objects

If you really want to get good at serializing, take some time to learn networking and sending data between clients

[fossil blaze]

How can I make the placement of objects on the shelf be correct when the rack is rotated in Y? The shelf is a child object of the rack

[latent latch]

If you child the objects to the shelf then you should have rotation relative to the shelf, no?

[fossil blaze]

Well, they're not the only ones spinning.

[placid edge]

bleed = 4
it's not giving me the first loop and total damage is equating to 6 instead of 10

[latent latch]

Do yourself a favor and instead of inlining everything just make some temporary variables and assign the values you're trying to append

[thin aurora]

Also constantly using GetComponent for the same components in general is a big no no

[leaden ice]

Debug.Log the variables involved at each point of this process and you'll clearly see what's happening

[placid edge]

I have Logged everywhere, its skipping the first loop

it goes 0,3,5,6

0+3+2+1

[steady bobcat]

the position needs to be local to the shelf. you can do Quaternion * Vector3 to rotate a local vector easily.

[placid edge]

this does look nicer though you're right

[steady bobcat]

✨ upgrade to using a debugger ✨

[placid edge]

the i var is actually not doing anything, can i just remove it?

[leaden ice]

What does that mean?

Which variable does that? The loop condition is on bleedDamage

Note that the incrementer is the LAST thing that runs each iteration

So it's not skipping anything

[placid edge]

so each loop it grabs the variable of bleed damage and adds it to hemorrhage then reduces bleed damage by 1

[leaden ice]

No

You have that backwards

It will reduce bleed then add to hemorrhage

The incrementer runs last

[placid edge]

ohhhhhhhhhh

🤔

[vestal arch]

this seems correct

[daring cove]

Whats the point of the loop? When you could multiply? Correct me if I'm wrong but seems a bit redundant to me.

[leaden ice]

The bleed -- should be the incrementer

And the hemorrhage+= bleed should be inside the loop

[placid edge]

oh you're so right

[placid edge]

how would you multiply this? i tohught there'd might be an equation for this i just couldnt find out what

[vestal arch]

it's the sum of integers from 1 to n, right?

that's n(n+1)/2

triangle numbers

[leaden ice]

That too^ yeah

you don't actually need a loop here

[placid edge]

tyty, i knew there had to be math for it

[daring cove]

Oh yeah I see what you are doing there nvm

[leaden ice]

Thanks Euler

[latent latch]

I would have done a for loop too cause I cant be bothered with math

[vestal arch]

i mean a loop would make more sense if you want each tick of bleed to be done individually over time (for example)

(for example, poison in peglin)

[daring cove]

It doesnt seem like its done over time the loop seems like its running inside OnCollisionEnter

[placid edge]

so bleed damage does that in EnemyStats. it ticks the damage then goes down by 1. This weapon grabs all the bleed damage and does it at once.

so instead of 4 ticks of 4+3+2+1 over 4 seconds, it does 10

it's supposed to be like a big bleed build cashout, where you build lots of bleed then hit the guy with this

yep all working good now, thanks guys :>

[fossil blaze]

I have the placement crooked, not the product rotation.

[steady bobcat]

i dont understand, need more information or some images of it in the scene view.

if elements are placed as children of a transform then use local positions for the parent so it works with the parent rotation

[reef lagoon]

So wondering if i wanted to make a top down pixelart game with equipables such as helmets, chestplates etc, and want it to show on the player when walking in 4 directions. Does anyone have any tips to how I could do this?

[fossil blaze]

Good

[steady bobcat]

Then yea use local positions for this "Rack" transform to place things in a row but locally

[hexed pecan]

Would be simpler to do it in local space

[fossil blaze]

I can't fix it.

[bleak meadow]

Hey guys! I have a peculiar problem. Anyone with experience with the new input system?

My problem is that two buttons triggers the same trigger even though they are mapped to two different buttons. I have checked my code, and as far as I can see, all events are separated to their respected button, but these two still trigger each other for some reason. 🤔

I'm testing with a controller

[hexed pecan]

Ok

[leaden ice]

show how you hooked them up to your code

Also #🖱️┃input-system

[bleak meadow]

aaah yeah! I will repost it there with the code

[steady bobcat]

its fixable you just need to re do how you pick a position for a child.
e.g. child.transform.localPosition = new Vector3(offset.x * index, 0f, 0f);
using local position means its relative to its parent always

[faint bridge]

I just realized i had to prevent diagonal movement and ive actually never done it before

Vector3 move = Vector3.ClampMagnitude(transform.right * x + transform.forward * z, 1);

Is this approved?

[vestal arch]

sure

assuming transform is only yawed, at least

[faint bridge]

not

I was mainly wondering about clampmagnitude and if its reliable

[vestal arch]

"reliable" how?

it does what it says it does

[faint bridge]

i mean reliable as in the same context as Void Update && void FixedUpdate

[leaden ice]

That doesn't clarify anything lol

[vestal arch]

yeah no clue what you mean

update and fixedupdate also do what they're supposed to

[leaden ice]

The function works properlly. There is no need to generally question if a function does what it says it does. You can usually assume it does.

[faint bridge]

update is frame based

[vestal arch]

ok?

[faint bridge]

ok let me clarify

are there any flaws

[vestal arch]

no?

it's a really simple function

[leaden ice]

Weird question to ask. What makes you suspicious of this function in particular?

You can generally assume functions do what they say they do, and do so without error.

[vestal arch]

i think you're asking about caveats?

but no, this is a really simple math function

[faint bridge]

I know it has a precision flaw at small number that's all I can think about but I was talking about in general, if there's any do's and dont's

[vestal arch]

both at small and large numbers, yes, that's how floating-point works

Vector3 also uses single-precision floats

that's just inherent

[leaden ice]

That's a floating point number restriction, not specific to this function at all

[vestal arch]

nothing to do with ClampMagnitude specifically

[faint bridge]

Ok, I just noticed how it acts when small numbers keep updating, it sometimes outputs a higher number

[leaden ice]

ClampMagnitude should never output a vector with a higher magnitude than what you put in

[rustic rain]

int animationClipLength = Mathf.RoundToInt(listClip.frameRate * listClip.length);
I have this calculation to get the frame length of an animation, but it seems to be exactly 1 frame short every time. Would this be the correct way to get the animation's frame length?

[vestal arch]

https://0.30000000000000004.com

[faint bridge]

I tried debugging it and prime numbers with 3 decimals output the square root of 7 which is very strange to me

[leaden ice]

huh?

[faint bridge]

I can't wrap my head around it

[vestal arch]

no clue what you mean there

[leaden ice]

you'd have to show eexactly what you're talking about

[faint bridge]

Clamp magnituding smaller numbers that are prime numbers

always makes it the square root of 7

instead of like 1

[leaden ice]

makes what the square root of 7

[faint bridge]

vector

[leaden ice]

ClampMagnitude takes a Vector input

[leaden ice]

you mean the components of the vector?

[vestal arch]

show some code

[faint bridge]

yeah

[vestal arch]

we have no idea what you're talking about

[leaden ice]

You'd have to show the exact inputs and outpus and the code you used.

because you're being extremely vague

[faint bridge]

Vector3 move = Vector3.ClampMagnitude(transform.right * x + transform.forward * z, 1);

I just use this, and i console log the values

[vestal arch]

ok, and what was the result?

[leaden ice]

ok and you would need to show us the values coming in and out for us to understand what you're talking about

Because a minute ago you were talking about prime numbers and sqrt of 7 and ...????

[hexed pecan]

None of the components of the resulting vector would be over 1 here

So idk what the square root of 7 is about

[faint bridge]

me neither i am so lost

thats why im asking i have no clue

[vestal arch]

we have no idea wtf you're talking about 😭

[faint bridge]

at this point i dont either

i just noticed that 2.4 is the square root of 7 so i went with it

2.6 my bad

[vestal arch]

it is not

[faint bridge]

pls forgive me

when doing the x and y inputs it returns 1 or -1, when you hold W + D its gonna be the square root of 2 based off of how fast you move when combining both axis

i accidentally put it +1 on top of the clamp thing

[vestal arch]

yes, that's how it's supposed to work

[faint bridge]

yeah

but i just

f*cked it up

[vestal arch]

well, half of the square root of 2

[faint bridge]

yeah but combined they are

and i put +1 so

i am just lost in the sauce here

[vestal arch]

why would you combine them

that's not how vectors work

[placid edge]

is there a Mathf.Ceil that rounds down or do I just -1 with it?

[vestal arch]

that's called Floor

also ceil-1 is not the same as floor

[lost rivet]

i am going to go insane, newtonsoft cant serialize vector3s?

[leaden ice]

It can when you have the Unity extensions installed

which should happen automatically if you installed it through the package manager afaik

[placid edge]

i figured -1 would have problems yeah ;/
OH you were talking to me when you said Floor OHHHHH Floor and Ceiling omg 😭

[faint bridge]

To prevent movement sliding should i floor it? or is there a better way

[leaden ice]

SHould you floor what?

What do you mean by "movement sliding"? That is really vague.

[vestal arch]

sliding?

[faint bridge]

we are talking about vectors

[vestal arch]

clearly not

[faint bridge]

Sliding as in when you release D, it moves you very slightly more

[placid edge]

they were responding to me

[leaden ice]

That is highly dependent on your movement code.

[lost rivet]

where can i get that?

[leaden ice]

Not intrinsic to the D key.

[leaden ice]

How did you install newtonsoft

[faint bridge]

What do you mean by "movement sliding"? That is really vague.

[vestal arch]

ceil(1)-1 = 0
floor(1) = 1

[lost rivet]

i did install package by name

i couldnt find it elsewhere

[faint bridge]

float x = Input.GetAxis("Horizontal");
float z = Input.GetAxis("Vertical");

Vector3 move = Vector3.ClampMagnitude(transform.right * x + transform.forward * z, 1);

controller.Move(move * speed * Time.deltaTime);```


very simplistic

[placid edge]

i think i may have interrupted something here

[leaden ice]

You need to also install this:
https://github.com/applejag/Newtonsoft.Json-for-Unity.Converters

[leaden ice]

your sliding comes from using Input.GetAxis

it has nothing to do with anything else

switch to Input.GetAxisRaw if you don't want it.

OOOps wrong reply. I meant @faint bridge

[faint bridge]

Okay thank you

That's much better, using what I originally had makes the movement feel unresponsive & washed out

[indigo orchid]

in this script I included a function to freeze animations and play them to complete them frame by frame but I want it for only walk and not for run but the run animation freezes and doesn't switch to the idle animation frames which I want pls help here is the script https://paste.ofcode.org/8F5y2sKHDeDp4UHvBXZ6gu

[lost rivet]

cant do it

cant find the package

[leaden ice]

Did you follow the instructions?
https://github.com/applejag/Newtonsoft.Json-for-Unity/wiki/Install-Converters-via-UPM

Make sure you follow this part assuming you don't have the scoped registry configured already:
https://github.com/applejag/Newtonsoft.Json-for-Unity/wiki/Install-Converters-via-UPM#if-you-dont-have-the-jillejrnewtonsoftjson-for-unity-scoped-registry-configured

[lost rivet]

what is all this stuff WHY DO I NEED TO DO ALL THS STUFF

i love friction

[hexed pecan]

Was there an issue with jsonutility? Do you need to serialize something it can't?

[leaden ice]

He's trying to serialize Vector3

which you need the Unity Converters package for

(you could of course also write your own custom converter but... the package exists already)

[lost rivet]

dictionaries too, which the json utils cant

[steady bobcat]

What about unity mathematics float3?

[latent latch]

I would just suggest sticking to arrays (with kvp structs) and building the dictionary at runtime

[leaden ice]

dictionaries work out of the box for newtonsoft

[lost rivet]

why?

[latent latch]

Just what I do I guess cause I cant be bothered fighting with Unity serialization

[steady bobcat]

yea its not hard for your structure to have a key and to make the dictionary after loading it

[hexed pecan]

They should really just add a serializable dictionary built in

[latent latch]

unity serialization is just weak

[lost rivet]

ok found it, its just the different ui that threw me off

[fossil blaze]

I didn't get it right, unfortunately.

[latent latch]

honestly worst part about Unity for me by a long shot

[lost rivet]

i mean fair i was wondering if there was any advantag to it

[latent latch]

the advantage is not relying on 3rd party serialization

[steady bobcat]

what prevents vector3 from being used? not being Serialized?

[lost rivet]

it gets into an infinite loop

from properties returning other vector3s

[vestal arch]

lmao

[lost rivet]

i guess they couldnt be bothered writing [jsonignore] or something

[leaden ice]

Yeah the converter package fixes that

[hexed pecan]

It's pretty fast

[lost rivet]

yes it seems to work now, many thank

[steady bobcat]

Because not everything has to be compatible with newtonsoft json by default but the new .net json serialization id expect now

[lost rivet]

tru

did take a while to setup but if it works it will b worth it

never did a proper save system before

not a good one i mean

[indigo orchid]

[errant flame]

System.InvalidOperationException: HashMap is full

How can i trace which hash map is exceed i opened stack trace btw also setting

      NativeLeakDetection.Mode = NativeLeakDetectionMode.EnabledWithStackTrace;

before the jobs

[hexed pecan]

Mate

Try to make your question more readable

That probably helps attract some helpers

[vestal arch]

look through the stacktrace

[errant flame]

its not showing the lines it only show JobHandle handle = job.Schedule(allCombinations.Count, 64); the line where i schedule 😄

i want to one more step to look which hashmap exceed its only says in this job there is a hashmap that exceed limit xd

[steady bobcat]

is it possible to debug in jobs? if so it may be able to break on the exception

[errant flame]

maybe i guess it should be, let me try to add try blocks to inspect i jsut wonder if there is a easier way 😄

[steady bobcat]

try adding a breakpoint but it may not work as its not managed code but native

[errant flame]

yeah maybe let me try

yeah found that **** 😄

[vestal arch]

there's no stack at all? not even when you click the error?

[young edge]

do you guys have any tutorials that are dedicated to unity scripting?

autocorrect

I mean

I can’t say it for some reason

a video that explains in depth about unity scripting

[vestal arch]

you can edit your message

in depth? probably not

you might want to see unity !learn

[tawny elk]

:teacher: Unity Learn ↗

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

[errant flame]

No if i click the error it goes the handle.Complete() ...

[young edge]

I’ll take a look

thanks

[vestal arch]

don't double click it

[errant flame]

there is a stack but its only shows until right before of the complete section not going further therefor i cant say that thing exploded etc

[vestal arch]

can you show it?

[errant flame]

board sorter 76 is

and line 312 the section exceed limit but if i add that try blocks then shows this

[vestal arch]

no, check the stack on the actual error, InvalidOperationException

[errant flame]

if i dont add that blocks it shows this

you mean this output right ?

[vestal arch]

yes

..but damn. that's unfortunate

[errant flame]

yeah 😄

[hexed pecan]

@errant flame What if you remove [BurstCompile]

[errant flame]

let me try that

yes than it show that , that's good to know 😄

[steady bobcat]

oh is it fixed capacity (not familiar with a lot of the unsafe collections)

[errant flame]

the key values are not fixed but the bag of the one key that holds its fixed i guess

[fossil blaze]

I didn't get it right, unfortunately.

I haven't been able to solve this problem for two days.

[steady bobcat]

i dunno what else to tell you sorry :/

[fossil blaze]

public Vector3 GetNextPlacementPosition()
        {
            Collider shelfCollider = GetComponent<Collider>();
            if (shelfCollider == null || maxItems <= 0)
            {
                return Vector3.zero;
            }
            
            float shelfLength = shelfCollider.bounds.size.x;
            Vector3 placementAxis = transform.right.normalized;
            
            if (placementAxis.x < 0)

            nextPosition.y = startingPosition.position.y;
            nextPosition.z = startingPosition.position.z;

            return nextPosition;
        }```
Let's look at the script together again, even chatgpt couldn't help me, I give him my code and he reworks it into a non-working one.

[hexed pecan]

Collider.bounds is axis aligned in the world space. Does not make sense to use it here

[latent latch]

oh no they said the c word

[leaden ice]

Especially not the x axis bit...

[fossil blaze]

and how do you do it right?

[hexed pecan]

Do it in local space like we suggested

You can make a float field for the width instead of using bounds

[fossil blaze]

Size 2

is how much in float?

[leaden ice]

2 is 2

[hexed pecan]

Float is.. a number

[latent latch]

may just be easier to make empty game objects as pivots on the shelf as children

[hexed pecan]

You could also just use the box collider's size

[hexed pecan]

I believe they have some sort of pivot, there's a transform startingPosition

Is that right?

[latent latch]

yeah if you did was a larger number size then you do raw calcs but if you're having trouble positions it may be better to define them

stick the local points into an array and do it that way

[fossil blaze]

I only have a problem with placement when the rack is rotated in the Y direction

[heady iris]

It's the size of the box collider in the local space of the object it is attached to.

so, for example, X=2 means that the box collider will have its left and right sides at X=-1 and X=1 in the object's local space (since the Center is at X=0)

the resulting world-space positions will depend on the transform of its object and of all its parents

You can construct a Bounds object out of the center and size (divided by 2, since the bounds wants half-extents), then use it to figure out local-space positions

Transform those points back into world-space at the end if you need to.

[fossil blaze]

Oh, still didn't make it.

[hexed pecan]

You need to show what you tried

[fossil blaze]

  public Vector3 GetNextPlacementPosition()
        {
            BoxCollider shelfCollider = GetComponent<BoxCollider>();
            if (shelfCollider == null || maxItems <= 0)
            {
                return startingPosition.position;
            }
            
            Vector3 localSize = shelfCollider.size;
            Vector3 localCenter = shelfCollider.center;
            
            float shelfLength = localSize.x;
            float spacing = shelfLength / maxItems;
            
            Vector3 localNextPosition = localCenter - new Vector3(shelfLength / 2, 0, 0);
            localNextPosition += new Vector3(spacing * placedItems.Count, 0, 0);
            Vector3 worldNextPosition = transform.TransformPoint(localNextPosition);
            
            worldNextPosition.y = startingPosition.position.y;
            worldNextPosition.z = startingPosition.position.z;

            return worldNextPosition;
        }```

[hexed pecan]

These lines don't make much sense herecs worldNextPosition.y = startingPosition.position.y; worldNextPosition.z = startingPosition.position.z;

You should probably do that in local space

localNextPosition.y = startingPosition.locallPosition.y etc.

Before converting to world space ofc

[fossil blaze]

Okay, I'll give it a try.

public Vector3 GetNextPlacementPosition()
        {
            BoxCollider shelfCollider = GetComponent<BoxCollider>();
            if (shelfCollider == null || maxItems <= 0)
            {
                return startingPosition.position;
            }

            Vector3 localSize = shelfCollider.size;

            float shelfLength = localSize.x;
            float spacing = shelfLength / maxItems;
            float localLeftEdge = -localSize.x / 2;
            
            Vector3 localNextPosition = new Vector3(localLeftEdge + spacing * placedItems.Count, startingPosition.localPosition.y, startingPosition.localPosition.z);
            
            return transform.TransformPoint(localNextPosition);
        }```

Now for some reason I have the goods placed from right to left and the placement starts from the center of the goods and not from the edge of the rack

[steady bobcat]

plz refer to things as the parent/container and children

[heady iris]

i don't understand what that would mean here

[steady bobcat]

they have the container which is trying to position its "children"
im not sure what "goods" or "rack" is

[heady iris]

You haven't accounted for the collider's center property.

[heady iris]

oh, I see; I was looking at the code and getting really confused lol

Also, if the items are appearing in weird spots (e.g. stuck halfway inside the shelf), make sure that their pivot points make sense

I'd expect to have the pivots at the bottom-center of each item

[steady bobcat]

Make sure your scene view is set to "pivot" and not "center" !!!!!!!!!!!!!!!!

[fossil blaze]

I can't solve this problem of product protruding over the shelf

[leaden ice]

sounds like shelfLength isn't correct

[fossil blaze]

public Vector3 GetNextPlacementPosition()
        {
            BoxCollider shelfCollider = GetComponent<BoxCollider>();
            if (shelfCollider == null || maxItems <= 0)
            {
                return startingPosition.position;
            }

            Vector3 localSize = shelfCollider.size;
            Vector3 localCenter = shelfCollider.center;

            float shelfLength = localSize.x;
            float spacing = shelfLength / maxItems;
            
            Vector3 localNextPosition = localCenter - new Vector3(shelfLength / 2, 0, 0);
            localNextPosition += new Vector3(spacing * placedItems.Count, 0, 0);
            
            localNextPosition.y = startingPosition.localPosition.y;
            localNextPosition.z = startingPosition.localPosition.z;

            return transform.TransformPoint(localNextPosition);
        }```

2 size

[leaden ice]

1. shelfLength isn't right
   or
2. You're not accounting for buffer spoace
   or
3. The starting pos on the left is not correct

[leaden ice]

show the gizmo for the ocllider? Is it placed correctly?

[hexed pecan]

Also is placeditems.Count 1 or 0 at the first iteration?

[leaden ice]

yeah what's the count there

And where's the pivot for the box object?

Doesn't seem the width of the placed items is taken into account

you're placing them directly on the edges of the shelf

[leaden ice]

Seems like this is starting at 1 instead of 0

[hexed pecan]

Yep

[leaden ice]

combined with placing things directly on the edges (no buffer being allowed for at the beginning/end

so you get an item half hanging off

[hexed pecan]

Is the rightmost item the first one in this screenshot?

[fossil blaze]

Thanks, bro. I got it.

but now how do you make the product left-to-right instead of right-to-left?

[hexed pecan]

You would just reverse your math in the x axis

Why do you need that tho?

I mean it is already left to right

Your camera is just not facing the same way as the shelf

[fossil blaze]

okay bro, ty

@hexed pecan @leaden ice I couldn't have done it without your help, thank you.

no

neither of those are static because neither of them are marked with the static modifier

[slow lodge]

someone doesn't have a first person movement code

huh

is it because I didn't reference a class inside of the class that I did reference?

well

that has

a lot of issues

[still jungle]

that was quick

[rigid island]

o.0f, tf

[vestal arch]

first off, configure your !ide

[tawny elk]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• :question: Other/None

[pastel idol]

please follow the tutorial more closely

[pastel idol]

Input, not "Imput"
Time.deltaTime, not Time.deltatime
also please try making the first letter in each name of a float, int, bool, and so on a lowercase letter

that means speed, not Speed

[rigid island]

they should first fix their IDE before spoonfeeding the answers

[slow lodge]

Type I did all the code, it asks me to put the capsule that creates the scripts, make the code that I send after I press the capsule again and put in the inspector to go to (add component) and put the created code and with that the character should move but it does not move

[still jungle]

those axis names also doesnt look right

[vestal arch]

also please try making the first letter in each name of a float, int, bool, and so on a lowercase letter
this is not necessarily correct.

casing/styling should be done by what kind of symbol it is, rather than the type.

[pastel idol]

idk, I always blame these things when something doesn't work

😂

force of habit

[vestal arch]

style is generally not a source of any behavioral problems

[slow lodge]

When I add the script that I created to the capsule that will be a player, I start the game and it does not move.

[vestal arch]

have you configured your ide

[still jungle]

how does something that "doesn't work" can be related to naming convention
well maybe if you write code without intellisense

[somber nacelle]

you shouldn't even be able to start the game with the current code you showed

[pastel idol]

configure your Visual studio with the tutorial above first
and please watch the youtube tutorial till the end, and carefully follow the uppercase and lowercase letter usage

[pastel idol]

you know, it doesn't apply to floats or any of these, but it still works with other functions like:

gameObject =/= GameObject
transform =/= Transform

[somber nacelle]

those are properties not functions

[vestal arch]

those aren't functions

and like i said before; the difference in casing is between what kind of symbol it is
the camelCased ones there are props, the PascalCased ones are types

[pastel idol]

what da hell

[somber nacelle]

read the entire message there

[still jungle]

it was probably too short to be valid

[vestal arch]

no, it's the asterisk

because the edit message button exists

        {
            TerrainGeneration tg = hit.collider.GetComponent<TerrainGeneration>();
            if (tg != null)

                int xPos = Mathf.RoundToInt(hit.point.x);
                float[] placements = tg.pathValues;
                int terrainWidth = tg.width;

                carridge.rotation = Quaternion.Slerp(carridge.rotation, Quaternion.LookRotation(target - carridge.position), rotationSpeed * Time.deltaTime);

                transform.position = Vector3.MoveTowards(current, target, speed * Time.deltaTime);
            }
        }
    }
}

this is happening

and this is the heirarchy

the carriage holder is because the rotation on the model wasnt right

and for scale

[leaden ice]

And does the object have a Rigidbody?

And how is the player following the object?

[flint plume]

the player is following it with rb.move

public class PlayerVelocity : MonoBehaviour
{
    private Rigidbody rb;
    private Vector3 position;
    private Quaternion rotation;
    void Start()
    {
        rb = transform.GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    void OnCollisionEnter(Collision collision)
    {
        position = collision.collider.transform.position;
        rotation = collision.collider.transform.rotation;
    }

    void OnCollisionStay(Collision collision)
    {
        if (!collision.transform.CompareTag("Carriage")) return;
        Vector3 offset = collision.collider.transform.position - position;
        Quaternion offsetR = collision.collider.transform.rotation * Quaternion.Inverse(rotation);
        position = collision.transform.position;
        rotation = collision.transform.rotation;
        rb.MovePosition(rb.transform.position + offset);
        rb.MoveRotation(rb.rotation * offsetR);
    }
}

the rotating part doesnt work rn

but the rest does

[leaden ice]

Does the train have a Rigidbody?

[flint plume]

no

[leaden ice]

What are the settings on the player's Rigidbody

[leaden ice]

and what other scripts are on the player?

[flint plume]

just movement on the rigidbody

for the rb*

[latent latch]

can you confirm it shakes if the player and camera arent on the train

[flint plume]

my power just cut out and I'm on phone right now I might not be able to get back on unity till tomorrow

[flint plume]

I'll do this when I can

[leaden ice]

It's either the player movement script breaking interpolation, or it's the train movement itself being jittery - possibly related to the RoundToInt that's happening?

I'm not sure I really follow the train movement code

[flint plume]

it might be the rounding

I don't think that's supposed to be there I probably got confused with the z axis movement because I made it unnecessarily complicated and was using rounding beforehand

[dawn belfry]

Could anyone point me in the right direction of something? I have several sprite sheets for my 2d game for weapons. Each sprite sheet is animated with the player holding a weapon. I now want to tell my script for anims that when the player has selected a weapon or press 1 or 2, to use those animations for the weapon like attacking, idle, walk left or right. Now should I use containers holding weapons with their scripts or how should I go about or think about this. Right now I have all my animations on one controller with custom names I call in code. But I'd rather write something like if player is walking left play the left walk animation that all weapon animations have a reference to walk left.

[steady bobcat]

If using an animator its kinda hard to do this cleanly as it depends on state names or param names 🤔
If you did the animations yourself it may be easier to configure them all by some enum or shared thing for these states

[split junco]

I need some help debugging an issue. I am able to use Quest Link and hit "Play" to interact with the scene. Everything works as it should. However, when I build the apk and use my Quest 3, a part of the simulation doesn't work. I am still able to move around and interact with the environment but two-three gameobjects don't function as they should.

I downloaded Android LogCat and I see error messages in it's console. It's pointing to lines of code that work perfectly fine on desktop through Quest Link but now it's an error. Here's an example:

2025/01/21 14:08:52.605 10463 10486 Error Unity NullReferenceException: Object reference not set to an instance of an object.

I have no idea how to solve this issue. Help?

[leaden ice]

Is this a debug build?

[split junco]

I don't know what you mean. Like, I build and run and I am using Quest 3 (not Quest Link). But since it's connected to Unity adb, I see logs through Android LogCat

[leaden ice]

I mean when you built the game, did you build it as a development build, or a release build?

[split junco]

I think it's release build

Yup. It's unchecked

[leaden ice]

You'll want to make a development build

And then do this as well: https://docs.unity3d.com/6000.0/Documentation/Manual/android-symbols.html

You'll need the debug symbols, then you can get exact error traces with filenames and line numbers

[split junco]

Thank you. I appreciate it. I'll check in after. Cheers!

[steady bobcat]

You only need symbols for native code stacks to decode function ptrs to names

the exception stack you sent is from "managed (i guess its cpp now but it was)" code hence it having info

[leaden ice]

Ok so for the managed code (which is what this is) just development build is ok?

I mean they have most of the info now other than line number I guess

[steady bobcat]

i dont actually know if line number can ever be restored tbh but symbols for dev builds is optional id say.
For prod builds you should keep them otherwise you are stuffed in future

services like bugsnag, sentry and firebase support symbol upload for auto crash stack decoding

[eager fulcrum]

Hey. I have text in 3d space and on click I need to open input field that will change the value of that text. How can I do this?

[rigid island]

pass it through a method or something, or share a variable

[eager fulcrum]

yes I know how to change the value, what I'm asking is how to actually add the input field to that

cuz there isn't a 3d space input field type

there is only text

[rigid island]

oh thought you wanted a UI panel popup, then in that case no you probably need worldspace canvas

or custom made one

[indigo drift]

I have a save system that turns an inventory into JSON, but for item sprites, it only saves instance IDs of the sprite so it stops working when you leave the game.

Would addressables be good to solve this?

[rigid island]

what are you trying to save exactly? what type are they

they have to be serializable

[indigo drift]

Well it's a sprite which I assume is why it just saves an instance ID, so I'm asking what I can do in order to save sprite information

[rigid island]

you can't directly save the Sprite type thats reference type

[steady bobcat]

addressable or in resources so they can be loaded correctly another time

[rigid island]

addressable are better version of resources

resources is old ,it all gets stuffed in one file so not very good compared to addressables, but for not many things is ok

[indigo drift]

Alright, I added some scriptable objects containing the sprites and other information so how would I then get these?

I'd have an inventory with different items so I want to be able to get whatever asset I need by name or something like that

[steady bobcat]

use AssetReference !

[indigo drift]

okay!

[steady bobcat]

that makes it easier to load an addressable later. Or you can ofc use the address string which can be anything you want (but needs to be unique)

tags work too if you want to say load all assets with a tag and sort em yourself by name for example

sorry, "labels"

[indigo drift]

Is it okay to use the address string? Like for example, if I load an inventory and the items are "sword" and "rock" , I need to get the addressables for the sword and rock items
Since there will be quite a few items I think it would be difficult to have like an inspector reference for all of them, so could I just get it by using "Assets/Script/Inventory/Items/Rock.asset" and "Assets/Script/Inventory/Items/Sword.asset" ?

[steady bobcat]

Yea ofc, in a few games i work on we have a address configured for many many items (1000+). I recommend making the address better first though and making some tools to validate addresses.

[indigo drift]

alright thank you so much

[steady bobcat]

the default address usually sucks. If you make a folder addressable btw it auto has the assets inside it as addressable!

[eager fulcrum]

okay I don't get it, I added Event Trigger to my 3D text and it doesnt trigger?

[steady bobcat]

does it have a collider that matches the physics raycaster you are using? You got an event system in the scene?

[eager fulcrum]

it doesn't have a collider and yes, I have event system on the scene

[steady bobcat]

If in the UI the a TMP ugui text will just work

[eager fulcrum]

no, its in 3D space

[indigo drift]

Sorry to ask again but do you mean I should just move the folder or is there a way to make a custom address?

[rigid island]

why would event trigger work on a mesh

you need the component for it (Physics Raycaster on camera) for 3d objects / colliders

[steady bobcat]

A folder can have a custom address as well as explicit assets. Right click to change address or do it in the inspector for the asset

[soft nymph]

What is a common architecture for signals that can be subsribed to. I have a monobehaviour that is designed to run bezier curve animations on game objects. I want a way so that anyplace in my codebase I can call that function without having to rely on the coupling of the two scripts

[wicked scroll]

your first statement seems at odds with the rest of your explanation to me

if what you want is a globally accessible script, a singleton or some kind of service locator are common solutions

or for some things, a static method

[rose willow]

how do I use that pixel per unit size and change the size of the camera without effecting pixel per unit size? I also have Vcam

[jagged plume]

I'm not sure why I'm getting ObjectDisposedException on heartContainersImgs which is a List<Image>

Isn't that how I'm supposed to destroy the gameObjects associated with the List<Image> then clear it?

[somber nacelle]

which line is the exception on

also unrelated to the exception, but to clear a list you can just call its Clear method, you don't need to instantiate a new list

[jagged plume]

Yeah I'm just trying things at this point tbh

The thing is that the bug occurs rarely

[somber nacelle]

It's not really saying a line

[somber nacelle]

that is an editor error

[jagged plume]

So what should I do

[somber nacelle]

ignore it because it is an editor error not directly related to your code

[jagged plume]

Well it is crashing my game

In the editor at least

[somber nacelle]

wdym by "crashing" your game

[jagged plume]

maybe not the build (?)

[somber nacelle]

also you said you were getting an ObjectDisposedException on heartContainersImgs. how did you even confirm that, or was that just a complete guess?

[soft nymph]

I guess thats true, my problem though is if I use a service or singleton then it becomes a dependency for anything calling that. I would ideally want to be able to call an event and not have to worry if the singleton is there or not

[jagged plume]

"ObjectDisposedException: SerializedProperty heartContainersImgs.Array.data[3] has disappeared!"

Well first of all the bug appeared after I introduced the deletion of the heartContainersImgs

and also well it's written here

[somber nacelle]

sounds like you want an event bus

[soft nymph]

maybe

[wicked scroll]

yeah, maybe something like https://github.com/PeturDarri/GenericEventBus

if you want to see how that might feel

[somber nacelle]

and again, what do you mean when you say it is "crashing" your game

[soft nymph]

oh thats nice, shame unity doesnt implement something natively

[wicked scroll]

I understand this desire but it's your game so I would just make sure the singleton is always there and save myself having to architect my game around this one trivially solvable problem (unless you have other good reasons too!)

[soft nymph]

yah it's just jarring, I come from Roblox which has some neat signal implementations that are basically event buses built into the engine so having to do it manually is a bit jarring

[wicked scroll]

Unity makes very few assumptions about what you're making which is both a blessing and a curse

I think it would make the engine much more approachable if it had worldstate and game modes a la Unreal, but then those things would be there and sometimes we'd have to fight them

[jagged plume]

So in the Editor it pauses the play mode for instance

[somber nacelle]

that's not crashing your game. you likely have error pause enabled on the console so any error is going to pause play mode, even if it is unrelated to play mode

[jagged plume]

So you suggest that I just ignore the error and deactivate error pause?

[somber nacelle]

well unless you have written some editor code that you've failed to mention, that's really all you can do

[jagged plume]

Can't I like fix my code to work well with Unity's serialized properties or something?

[pallid rampart]

Can somebody look at this and give me a hand? I'm not quite sure how to figure out which slice of my pie chart my mouse is hovering over.

https://gamedev.stackexchange.com/q/212782/60136

[somber nacelle]

there is nothing you are doing wrong here, except where you "clear" the list by removing all elements then just instantiating a new one anyway

[jagged plume]

Okay well after I unchecked error pause I don't seem to get much issues now and I cleaned my code back to be consistent with what you suggested I think

[somber nacelle]

you're showing the wrong loop there but alright

[stark sun]

https://pastebin.com/HPePvkJj grab script
https://pastebin.com/UFaeAgpD lever script
https://pastebin.com/aeE4Gcf0 trapdoor script
the balance script I didnt include just have rigidbody2D.Moverotation()

problem is when I grab to pull the lever, its like changing its limits the second time I grab.It cant get past a point by grabbing but I can push it with my body.

[steady bobcat]

consider not doing GetChild() twice

[still jungle]

there are not enought informations to even look at that, you should show the inspector of the lever instead of square which strangely change position for no reason, and explain your implementation and how it supposed to work and whats the current outcome

[stark sun]

nothing changes in the inspector

I mean the problem is once I fully rotate (or just pull it to a side) it to one side, I cant get it to other side without using body(without using the grab function)

[still jungle]

then make it to ignore to move when its not grabbed

and when its grabbed it should have start position and end position and shouldnt pass those values in any circumenstances

[stark sun]

moving it with my body is not a problem that can stay

[still jungle]

clamp lever rotation then

[stark sun]

I dont know if that will work because we have a value we cant pass not a value we dont want to pass

[still jungle]

whats the angle limits?

[stark sun]

but not like it looks

[tired shore]

What's the best way to handle third person shooter bullets? Spawning at barrel and pointing to camera center works in most cases, but there's lots of small issues when near walls/cover that block the shot. Is it better to spawn visual at barrel but still spawn actual bullet at camera? Something else?

[stark sun]

some games use rays for bullets

it depends on you

[tired shore]

I want both. Think Gears of War. It's probably a raycast from center, but also the visual bullet comes from barrel.

[stark sun]

ahh you said third person

I dont know much about it

[still jungle]

your mechanics implementation make no sense

[still jungle]

big force lets you break the angle limits and let you reach open position (30*)
