[flat slate]

i made a ontriggerenter2d event but the problem is that the Children of the Object where the colliding script is collides aswell with the other objects

how can i avoid that

[swift crag]

There are several ways to get input.

[cosmic quail]

check for a specific tag when it collides maybe? or use collision layers

[swift crag]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.7/manual/Workflows.html

[earnest atlas]

They made it like this.

I did like onDisable

[flat slate]

i did use a tag

but it ignores that the children has got another tag

[swift crag]

Yes, you tend to use both of these styles together

The former makes sense for non-buttons

things that don't "happen" at a specific moment

The latter makes sense for buttons

you want to do something in response to the Fire action being performed

[earnest atlas]

Im just confused a bit how everything is called what is better and what is corect

[faint sluice]

First one you call manually somewhere in like update or something

Second one is sort of callback that will automatically get called when that button gives some sort of input

[timid saffron]

oh thanks man minor mistake again. this part is alittle hard and overwhelming sorry

[cosmic quail]

i'd search on google why that happens and maybe you'll find a solution

[earnest atlas]

So second one is better considered it wont get called constantly?

[swift crag]

Neither is "better"

They're two different use-cases.

[faint sluice]

Again as fen said, both are used together usually

[swift crag]

I use both.

            Vector2 moveInput = moveAction.action.ReadValue<Vector2>();
            Vector3 worldMove = entity.transform.TransformDirection(new Vector3(moveInput.x, 0, moveInput.y));

            Vector2 lookInput = lookAction.action.ReadValue<Vector2>();
            lookInput += gyroLookAction.action.ReadValue<Vector2>();

[swift crag]

I use ReadValue for things I need values from every frame

            foreach (var actionRef in callbacks.Keys)
            {
                actionRef.action.performed += callbacks[actionRef];
            }

I subscribe to the performed event for things that I need to run a method in response to.

[faint sluice]

It's alright happens all the time to the best of us haha

[faint sluice]

Can you explain to me how did you store values in there xD
I'm mindblown

[swift crag]

callbacks is a :

Dictionary<InputActionReference, System.Action<InputAction.CallbackContext>> callbacks;

            actions.Add(walkAction);
            actions.Add(crouchAction);
            actions.Add(runAction);

runs in Awake

I just did this because I didn't like the repetitive subscribe / unsubscribe code

[faint sluice]

Ahhh lmao

[swift crag]

I'm not using the PlayerInput to directly call methods

just InputActionReference fields

[faint sluice]

How do you get rid of an "unwanted action" in this method??

[swift crag]

i don't understand what you mean

[faint sluice]

Say you don't want to subscribe to crouch anymore in following builds

[swift crag]

then I'd remove it from the dictionary

[faint sluice]

Wouldn't actions get messed up?

[swift crag]

oh, I just noticed that this was the wrong code lol

            callbacks[interactAction] = Act;
            callbacks[discardAction] = Act;

(the method looks at the action that triggered it to decide how to handle the input)

[swift crag]

actions is just a List<InputActionReference>

everything in that list gets enabled

[swift crag]

and everything in callbacks is used to subscribe to events

[swift crag]

i should probably just get rid of that...i added another system whose job is to correctly enable and disable input action maps

[faint sluice]

Ahhh got it, makes sense now

[swift crag]

i shouldn't have anything enabling individual actions

[faint sluice]

I'll probably still stick to my caveman ways as it's easier to read and ignore but cool to learn new ways

[quick dawn]

` Vector3 followPositionPlayer = Vector3.Lerp(transform.position, physicsPlayer.position, Time.deltaTime * menuFollowPositionSpeed);
Vector3 followRotationPlayer = Vector3.Lerp(transform.eulerAngles, physicsPlayer.eulerAngles, Time.deltaTime * menuFollowRotationSpeed);

    Vector3 followRotationHead = Vector3.Lerp(transform.eulerAngles, physicsPlayerHead.eulerAngles, Time.deltaTime * menuFollowRotationSpeed);

    transform.position = new Vector3(followPositionHead.x, followPositionPlayer.y, followPositionHead.z);
    transform.eulerAngles = new Vector3(followRotationPlayer.x, followRotationHead.y, followRotationPlayer.z);`

can someone help me fix the euler angles lerp please

it snaps weirdly

and when i tried quaternion lerp it didnt work

[timid saffron]

and what Ive realized is that I wrote this code and thought made sense (I think it does) this code is for destroying animals if their position is greater than...

but what Ive realized is clones of prefabs Z value dont increase or increase very little amounts

even though they are very far away

[faint sluice]

Define "snaps weirdly"

[quick dawn]

like if it rotates past 360 degrees it like starts rotating backwards

[polar acorn]

What you see in the inspector is local position. Your code is checking world position. Does this object have a parent

[timid saffron]

yes. the parent spawns the children

it is prefab

[polar acorn]

What position is the parent at

[timid saffron]

these are spawned

you mean spawn manager?

[polar acorn]

I mean the parent of the object that you say doesn't move much in Z

[timid saffron]

this?

spawnmanager spawns clones of this

im not sure if its like parent and children

I use this code to call them

[polar acorn]

You know what nevermind I've decided I don't care

I don't have the patience to play 20 questions with someone who doesn't understand what I'm asking

I'm too tired today

[quick dawn]

thats deep

[timid saffron]

yeah

I didnt assing any parent or children so I didnt quite get what youre asking for

this is the best I can show you

[summer stump]

That's the child, which is a local position

See the thing right above the thing you circled on the left

That's the parent

Wait, maybe i'm wrong

I can barely read anything with that color

[quick dawn]

can somebody help me change the vector lerping to quaternion lerping pls

[summer stump]

Ok yeah, that is the world position

[quick dawn]

i tried and it didnt work

[timid saffron]

Fox(clone)
down arrow
SM_fox_01
sm_fox_02...

you said you couldnt read so I wrote what wrote there 😄

[summer stump]

#💻┃code-beginner message

[timid saffron]

okay didnt see that

[summer stump]

THIS one is a child though
#💻┃code-beginner message

The sm ones are children of the prefab it looks like (as you showed with the fox)

So it's local position

To be clear, the things with a down arrow are called parents (if collapsed, it's a right arrow)

[swift crag]

Understanding the Transform hierarchy is very important.

It's fundamental to how your objects are positioned in the scene.

https://docs.unity3d.com/Manual/class-Transform.html

The relevant point here is that, if your parent is scaled up, a small change in your local position results in a huge change in your world position.

If your parent's scale is [10, 10, 10] and your local position is [1, 2, 3], your world position is [10, 20, 30]

[shell sorrel]

the concepts of transforms, parent objects and child objects also carries over into DCC apps like blender and maya as well, pretty much anything with 3d and a lot of 2d things as well

[swift crag]

(assuming that the parent is not rotated and is at the origin)

[timid saffron]

here instead of && i used || and problem fixed

I also tried local.transform

instead of transform

but that didnt do much

[swift crag]

it sounds like you just tried random changes until it kind of worked

did you read anything we wrote?

[summer stump]

You just need to look at the parent transform

[noble summit]

what does ForceMode.Impulse do

[timid saffron]

I read all of them

[swift crag]

https://docs.unity3d.com/ScriptReference/ForceMode.Impulse.html

links too fast

https://docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html see also

it describes all four modes

[summer stump]

If you misunderstood anything, let us know. Because nothing you tried makes sense based on what we said

[noble summit]

no i need a quick summary of one sentence on to what it does

[summer stump]

Adds force to a rigidbody in a way

[swift crag]

is there something wrong with the descriptions on the pages

[timid saffron]

well yeah but I didnt wanna ask more questions because I asked way too many already

[noble summit]

im just not reading allat

[swift crag]

I should point out that the second page I linked, indeed, has two-sentence descriptions

[swift crag]

sigh

[noble summit]

2 times more than im willing to read

[noble summit]

in what way

[summer stump]

Then programming is not for you. Good luck

[swift crag]

this is ridiculous

[summer stump]

In a way described by the links fen sent

[swift crag]

put down your phone and read a single page of text

[timid saffron]

https://screenrec.com/share/pudng1mz6e

this was what I was trying to do

[noble summit]

all im understanding is that it makes the force happen faster

[summer stump]

There ya go! 🎉

[noble summit]

huh.

[summer stump]

You read it and figured it out sorta

[swift crag]

it's all you're going to understand if you don't read the documentation

[noble summit]

i did

[noble summit]

what is dt

[summer stump]

DeltaTime

[noble summit]

so impulse is just removing framerate stuff

[swift crag]

no, it is not "just removing framerate stuff"

[noble summit]

thats what im seeing

[swift crag]

it applies an instantaneous force to the rigidbody

[polar acorn]

then you should try reading the words on the picture instead of just the code

[noble summit]

doesnt seem very instant to me

[median ruin]

why does this happen, I'm very confused?

[noble summit]

is just using force making it accelerate or something

[summer stump]

Seeming and being are two different things

[rocky canyon]

ur using names you probably shouldnt use

[median ruin]

Hmm okay I see

[quick dawn]

how to quaternion lerp on two axis please

euler didnt work

[median ruin]

But why would it care?

[rocky canyon]

show the full code.. i think its just out of place

outside the code block

[swift crag]

Show all of the code

without the big popup getting in the way

[summer stump]

Don't ping people you are not in a conversation with please #📖┃code-of-conduct

[swift crag]

the entire script would be ideal

[quick dawn]

mbmb

[summer stump]

First of all, though, never multiply by deltaTime in lerp
https://unity.huh.how/lerp/wrong-lerp

[median ruin]

public class UIPopupTrigger : MonoBehaviour
{
    // Start is called before the first frame update
    private bool IsTriggered = false;
    private GameObject Trigger;
    private GameObject CursorText;
    private DetectArea PopupTrigger;
    [SerializeField] string text = "Press E to interact";

    void Start()
    {
        Trigger = transform.Find("proximity").gameObject;
        Trigger

        CursorText = GameObject.Find("GameManager/GameHUD/Popup/CursorText");
        //textmeshpro
        CursorText.GetComponent<TMP_Text>().text = text;
        CursorText.SetActive(false);
    }
}

[swift crag]

oh, that's just because you haven't written anything more

[rocky canyon]

well if u just put Trigger out in the open w/ nothng ele it'll error

[swift crag]

Trigger is not a valid statement

[polar acorn]

If you delete the unfinished line, do you get an error on the actual line before it

[rocky canyon]

finish the line 😉

[swift crag]

it's been left hanging

[quick dawn]

ik abt that but it doesnt have to be perfect

[summer stump]

Does it have to be functional?

[quick dawn]

alr ill change it

but im js tryna figure out the quaternion problem

bc it doesnt work at all then

[summer stump]

Well the dt was part of the problem I bet. But I suck at rotations.
Is there a reason you chose lerp other rotation methods though?

[swift crag]

Quaternion.RotateTowards will steadily rotate towards a target.

[quick dawn]

it looks nice

[summer stump]

The whole code is wild honestly, not sure what the goal even is

[quick dawn]

yeah icl

im restarting

[spice breach]

I'm attempting to make a maze generator that can choose from different Node prefabs, the generator works, I'm having trouble selecting a random Prefab to use for the maze

[swift crag]

Your types don't match.

prefabChoice is an array of GameObjects

But you're trying to store the instance into a MazeNode variable

Perhaps you meant to have an array of MazeNodes?

If you instantiate a component, Unity copies the entire game object

[spice breach]

Yeah i just clocked actually thanks so much

cant believe I made that mistake

[spice breach]

to be honest I didnt think you could make a list of objects that derive from a class so easily like that

[swift crag]

you can make an array of whatever you want

[spice breach]

ended up getting an error telling me that the object i wanted to instantiate was null but it fixed itself somehow

[swift crag]

there's nothing special about GameObject

[swift crag]

you may need to re-assign things in the inspector

[ivory bobcat]

- GameObject[]
+ MazeNode[]```

[polar acorn]

fancy

[wanton cargo]

Hi so I can't seem to figure this out, I have a robot arm with two bones and it needs to calculate the angle at which the bones have to be in order for the end of the second bone to end up at a target position, but I have no idea how to approach this

Preferably while rotating on only one axis

[swift crag]

this is inverse kinematics

check out https://blog.unity.com/engine-platform/getting-started-with-2d-inverse-kinematics

[wanton cargo]

i was trying that but I can't get it to work right, it either messes up completely or ends up on the completely wrong position, or uses multiple axis

[wanton cargo]

Feels a bit dumb to ask but.. how would I define what axis it should rotate on 😅 as I need it to do it in 3d space but only on the local x axis

[shell sorrel]

transform.rotation = Quaternion.AngleAxis(30f, Vector3.right);
would rotate 30 degress around the x axis

[wanton cargo]

I understand that but I meant with IK

apologies for confusion

[shell sorrel]

oh now its a much more complex question

[wanton cargo]

yeah 😅 i have been stuck on this for a few days now

[swift crag]

I would suggest making the most basic IK setup possible

[verbal dome]

I dont really use builtin IK but the axis would probably be your limb's "right" axis (often transform.right) or a cross product of the two limb's directions wont work if the limb is straight

[short hazel]

Some IK rigs have a polar bone, which dictates towards where the bend is directed, but I don't know if Unity has support for that built-in

[swift crag]

I imagine it's different in 2D

[swift crag]

oh wait, this is in 3D, isn't it?

[wanton cargo]

Yes it's in 3d

[swift crag]

I'm not sure I got that in my head, sorry

[wanton cargo]

No problem haha

[swift crag]

2D IK won't help you here

[wanton cargo]

ok that's what I assumed, but worth a shot I suppose

[swift crag]

I also haven't really used Animation Rigging much

that's a 3D package

[wanton cargo]

I had a working IK setup before but I couldn't get it to work with constraints

[swift crag]

I mostly use FinalIK, which is third-party. I need to give Animation Rigging another go

[wanton cargo]

FinalIK is 90$ 😭

[swift crag]

Yep. It works real nice, though!

[wanton cargo]

I do not have 90$ to spare 🫡

so I will try to find an alternative

[earnest atlas]

Gimp 😄

[summer stump]

How would gimp help here?

Gimp is nice though for sure

[earnest atlas]

no idea I came late

[summer stump]

Ah ok, it has nothing to do with this

[swift crag]

yes, we're talking about inverse kinematics

[rich adder]

wait for a sale

[wanton cargo]

I managed to solve my problem 🤠 package called Animation Rigging

[rich adder]

Yeah its good one

buggy but getting ok

[wanton cargo]

Yee got it working with what I want so I'm happy 😊

[tender breach]

How do I change the variable of a clone?

I'll show the code when I feel like it.

[slender nymph]

Instantiate returns a reference to the instantiated object. so you use that reference to access any public members

[tender breach]

I don't understand what you mean by that.

[slender nymph]

that's too bad. you didn't bother showing code so i cannot suggest any other info 🤷‍♂️

[rare basin]

the fuck

[wanton cargo]

variable = instantiate(etc)
then reference variable (if i remember correctly)

[tender breach]

Here's the code: https://pastecode.io/s/xp91ias7

[rare basin]

oh lord

that is unreadable

[wanton cargo]

brother discovered an if statement and used it everywhere

[earnest atlas]

Whoever delt with Unity FPS assets on player controller. How does it read movements and presses?

[summer stump]

It's wild how much better the formatting is, and yet still so horrific

[tender breach]

I formatted it!

[wanton cargo]

We know!

😂

[slender nymph]

you have been told time and time again that you need to fix the formatting for your code. i'm sure you've also been told at least multiple times that you should be sharing your code using a site that adds syntax highlighting because that terrible formatting + lack of syntax highlighting makes that entirely unreadable

[summer stump]

Kinda, a little

[tender breach]

I formatted it! Honest!

[earnest atlas]

AHAHaha

It was worse?

And my teacher complained that looking into my code was bad

[summer stump]

I remember what it was before. And yes, this IS different, and slightly better. But it is still so far from what it should be

[slender nymph]

your configured IDE should be able to format it automatically with just a couple of key strokes

[earnest atlas]

https://hatebin.com/

This is unity asset player controller. How does it get movement and other things? I cant find references to inputs?

[short hazel]

Yeah that one is tame. One time it was like this, but without the indentation

[slender nymph]

make sure you've selected the save button on there. or use a different site if you cannot get that one to work

I think I found it, its directly accessing inputs huh

[slender nymph]

it uses the Input System with the PlayerInput component to get input

[earnest atlas]

yeah it just does it differently from what I got told

Also it has this bait

https://paste.myst.rs/n53t08k7

It exists, but it appears not to be used for anything

[slender nymph]

it is used for the input . . .

[earnest atlas]

Probably on phone

Its not accessed anywhere at player

[slender nymph]

the PlayerInput component sends the input messages to the StarterAssetsInput component. the FirstPersonController component access the StarterAssetsInput component for the input

[slender nymph]

it's literally the _input variable on the FirstPersonController component

[earnest atlas]

But this code has not a single reference that PlayerController accesses

wait

#💻┃code-beginner message

[earnest atlas]

What happens if I generate another instance of this class?

Or there only can be one? (or it explodes)

[slender nymph]

wdym by generate another instance? none of these are singletons. you can have as many different instances of these objects as you'd like

[earnest atlas]

Well last time I generated another istance of controllers they broke

Might have been my fault

But not sure

[slender nymph]

again, what do you mean by generated another instance

[earnest atlas]

StarterAssetsInputs Inputs
Inputs = new();

[slender nymph]

well that's just incorrect

you do not new() components

[earnest atlas]

that just example

If there are 2 components will it break or not?

[slender nymph]

surely you know how to read, right?

[earnest atlas]

Link?

[slender nymph]

#💻┃code-beginner message

[earnest atlas]

I mean

Okey gonna test if it explodes

Issue is not that its singleton

Or not

Issue is if there are multiple instances of this Component aparently

[slender nymph]

do you know what a singleton is? it's literally a type of object that forces only a single instance to ever exist. these components are not singletons therefore more than one can exist at any given time

[polar acorn]

Make sure that there are no compile errors and that the file name and class name match

[earnest atlas]

you dont understand what I mean

[slender nymph]

of course how you use something also matters

[slender nymph]

i understand perfectly what you mean. you just haven't bothered actually explaining anything besides just saying "will this explode"

[earnest atlas]

As mentioned I have mentioned to mention that when I created that class twice controlls broke

[slender nymph]

i know perfectly well that you are likely experiencing issues where all of the objects with these components on them are all reacting to the same input. of course that has nothing to do with having more than one of these components on it

the issue is obviously that they are all set up with the same input

for future reference, try fucking explaining what is happening instead of assuming everyone can read your mind and knows exactly what you mean when you say things explode with more than one of those components

[earnest atlas]

Issue mostly comes with me not knowing terminology and thinking that I explained it in a wrong way.

[slender nymph]

the issue is that you didn't explain anything at all

[earnest atlas]

Im pretty sure I did.

Anyway how does Unity Input system actually references this class?

[slender nymph]

it doesn't

the PlayerInput component sends messages to all of the components on the same object

but you can read the documentation pinned in #🖱️┃input-system if you want to learn how to use it

loop until you have reached the length of the array instead of an arbitrary number

[slender nymph]

and what about this did not work

[modest dust]

Go through a C# course, not a Unity course

[rich adder]

yes you lack the basics of working with array

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/collections

[flat slate]

the problem is that when i punch the first coroutin estarts but when i start punching when the first coroutine is still running the "isfighting" bool will be set to false fto fast

[polar acorn]

Either have 10 things in the array or don't try to get the first 10 things in the array

[edgy sedge]

I did do a small C# course but I find it easier learning while doing than not doing.

[flat slate]

u know what i mean?

[edgy sedge]

👍

[polar acorn]

Assuming you are actually starting the coroutine somewhere, isFighting becomes false 5 seconds after starting the coroutine

[rich adder]

doing isnt going to get you anywhere you if you don't know the basics available to you.
Instead of using magic number like 9.
Your looop would have the products[i].Length as limit

[edgy sedge]

Thanks mate. Will give it a go.

[flat slate]

ye but when i punch 1sec after the first coroutine starts, for example isfighting will be set to false not 5sec but 4sec after that and the second coroutine will be ignored

[rich adder]

dont forget to check the link I've sent that descibes this process

Thanks mate.

[slender nymph]

show the full code

[polar acorn]

Are you intending to be able to start another coroutine while the old one is still running? I thought this was for a cooldown

[faint sluice]

Both coroutine start with your bool starting at true state, first one will be over in 5 second resulting in false state, if you started second coroutine withing 5 seconds of first one, ofcourse it will feel like second one has been completely ignored

[faint sluice]

Doesn't mean it has been

[modest dust]

Well, it was a small course indeed if you're asking about array bounds now. Basics are important, go and make sure you understand them all more or less before trying to do anything meaningful in Unity, or you're gonna have a fair amount of similar issues along the way, which are not even Unity-related

isAttacking and isFighting both seem to be cooldowns of some sort. Why do you have both?

[flat slate]

isfighting is for something else

[faint sluice]

Use distinct names, or it will get confusing

[flat slate]

i try to stop all coroutines beore starting the coroutines

works now

thanks

[flat slate]

ye

[earnest atlas]

Box I looked up the API and other guide they have linked and the way they explained is the same as I got tought.

I havent found anything similar to what is done here?

[slender nymph]

guess that means you didn't pay too much attention to this

[earnest atlas]

I went page by page

They do the same thing i did

[slender nymph]

apparently not

they very clearly use the PlayerInput component there

[earnest atlas]

Where is the no autogenerated class

[slender nymph]

literally the first part

[earnest atlas]

Link

I might be blind but what they did so far is almost the same

[slender nymph]

it's literally the first fucking part of that course you linked

i don't even see anywhere that they do use the autogenerated c# class for that

[earnest atlas]

{
   Vector2 movementVector = movementValue.Get<Vector2>();
 
     movementX = movementVector.x;
     movementY = movementVector.y;
}```

[slender nymph]

yes, that is literally not using the autogenerated c# class

[earnest atlas]

public void OnMove(InputValue value)
{
    MoveInput(value.Get<Vector2>());
}```

[slender nymph]

that is using the PlayerInput component. just like the StarterAssetsInput component does

[earnest atlas]

WHAT is calling ONMOVE?//

[slender nymph]

the PlayerInput component

it does not call it directly, it sends the OnMove message to all components attached to the same object

#💻┃code-beginner message

[earnest atlas]

So basically if I create Shoot inside the controll component I need to create OnShoot so it gets a call?

[slender nymph]

again read the docs

[flat slate]

can u do 2 colliders in one object but they collide with diferent objects?

[earnest atlas]

yes]

[rare basin]

[flat slate]

how

[rare basin]

add 2nd collider component

[earnest atlas]

So I was correct OnShoot

[flat slate]

but i want that they collide different

[slender nymph]

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

[flat slate]

thanks

thats not what i meant

[slender nymph]

then you need to explain what you mean

because that absolutely will allow two different colliders on the same object to collide with different objects. you just have to set up the layer overrides on the individual colliders

[flat slate]

okay

then im just dumb

[swift crag]

https://docs.unity3d.com/ScriptReference/Collider-excludeLayers.html
https://docs.unity3d.com/ScriptReference/Collider-includeLayers.html

You need to use these properties to override which layers the collider will interact with.

(they can be configured in the inspector)

[flat slate]

i did it like that

is that correct

[rare basin]

[flat slate]

doesnt work

wait

[ivory bobcat]

What doesn't work?

[flat slate]

Works now

[swift crag]

is that error actually related to the code you showed?

[dire tartan]

im trying to make an active ragdol and need some help

im setting the target rotation of my ragdol to another model doing animations but its not copying the animation and im not sure what to change to fix it

[prime cobalt]

Is there a way to get the current volume of an audio clip and turn it into a float? So like a head can bob around with its rotation dependant on the volume of an audio clip it plays.

[ivory bobcat]

You'd probably check the audio source.

It should be the object that contains the current status of what's being played. The clip would just be data.

[prime cobalt]

Ok thanks

[ivory bobcat]

The audio source doc: https://docs.unity3d.com/ScriptReference/AudioSource.html

[charred spoke]

https://docs.unity3d.com/ScriptReference/AudioSource.GetSpectrumData.html you dont want the volume you want this data

[earnest atlas]

Only way to expose variable to inspector is to serialize it or make it public?

[charred spoke]

Well yes

[earnest atlas]

I just want to see sort of debug states

[charred spoke]

Debug states of what ?

[earnest atlas]

Basically see values without using serialize

Its not possible?

[charred spoke]

Debug.Log exists

[prime cobalt]

thanks

[earnest atlas]

Not log

[ivory bobcat]

What do you mean by that?

Sounds very explicit..

[earnest atlas]

Just show variables without making lines of variables with serialize

[ivory bobcat]

"making lines"?

[charred spoke]

The variables need to be serialized in order to appear in the inspector

[earnest atlas]

I just dont want this

its a metoforical representation

[ivory bobcat]

Doesn't look complicated at all.. 🤔

[swift crag]

You're going to need to do something for each value you want to view, yes

It is annoying that there's no built-in "display" feature

[ivory bobcat]

Hopefully it isn't a wanting to type less issue.

[earnest atlas]

does serialize works when you have multiple variables in line?
Like
bool a,b,c,d

[graceful citrus]

the code below is producing the image above. why are the prefabs being made in this pattern? i want them randomly across the map but thats not what its doing at all

    [SerializeField] private playerJoin players;

    [SerializeField] private GameObject radio;

    void Start()
    {
        for (int i = 0; i < 100; i++)
        {
            instanting(radio);
        }
    }
    void instanting(GameObject instantObject)
    {
        transform.position = new Vector3(UnityEngine.Random.Range(-384, 384), 512, UnityEngine.Random.Range(-384, 384));
        GameObject instance = Instantiate(instantObject, transform);
        if (instantObject == radio)
        {
            instance.GetComponent<threeDimensionalAudio>().clint = players;
        }
    }

[rare basin]

[modest dust]

You can just switch your inspector mode to debug to see all the fields

[earnest atlas]

You mean in VS studio?

[modest dust]

In Unity.

[graceful citrus]

it is a distinct curve

[ivory bobcat]

They're referring to the unity inspector

[graceful citrus]

you'd think with randomness that wouldn't happen

but it seems unrandom

[night mural]

with randomness, anything can happen!

is it really consistent every time?

[graceful citrus]

it seems so

its literally supposed to be random

its not even supposed to be a straight pattern

its supposed to be random points on a lateral grid

[night mural]

but they're the same every time?

[graceful citrus]

but its creating a completely out-of-left-field pattern

[graceful citrus]

i mean, look at the code

[night mural]

you mean like a...random pattern?

[graceful citrus]

i see no reason it would do that

[night mural]

do what

[graceful citrus]

make the pattern it does

[median ruin]

how do you know when an animator finish animating it's state?

[night mural]

and this pattern is the same every time?

[ivory bobcat]

I'm assuming they're referring to this

[graceful citrus]

they call start at the same point, then disperse in this pattern

this pattern

again

a second time

tf is happening

[earnest atlas]

Quantum Mechanics

Nothing is random

[ivory bobcat]

It would seems you're only offsetting the object relative to the previous

Visually

[graceful citrus]

but what do i do to stop that

do i wait a second between each one

each instantitiate

[night mural]

is your camera oriented correctly? we're looking at x/z right now?

or x/y?

[graceful citrus]

x/y

its supposed to be x/z

in the code, y is fixed

yet, the y is changing in this pattern

[night mural]

so we're looking at x/z?

[graceful citrus]

no we're looking at x/y

[night mural]

but you set y to be 512 always

[graceful citrus]

correct

i am just as confused as you are

[night mural]

what's it look like from another angle? i remain unconvinced

[ivory bobcat]

I noticed that they're rotated. Do you've got any other code modifying the transform of these objects?

[graceful citrus]

not to my knowledge

[graceful citrus]

would you like a mp4

[night mural]

oh what are you even doing here

[graceful citrus]

what am i doing here?

[night mural]

what object is this script on? because transform.position = will move that object, not position the object you spawned

[graceful citrus]

ik

[night mural]

you should be spawning your object, then setting its position to your random value

[graceful citrus]

but when you spawn a prefab it spawns at the object

i mean that would also work probably

ill try that rq

[polar acorn]

No it doesn't

[graceful citrus]

it did from my experience

[polar acorn]

It spawns at the location you specify in the parameter

if you don't provide one, it uses the value of the prefab itself

[median ruin]

Is there a way to tell when an animation is done? I've tried using normalizedTime and the length of the animation but I couldn't get it to work properly.

[graceful citrus]

ahh, i should do that

[rancid tinsel]

since its max exclusive, would i need to do blockPrefabs.Length + 1 in order to have all the options in the array be possible?

[polar acorn]

The cleanest way is to add in an Animation Event which can call any function
https://docs.unity3d.com/Manual/script-AnimationWindowEvent.html

[median ruin]

uh oh I see

I was wondering what you used those for lo

[polar acorn]

The reason it is max exclusive is specifically so that what you've done here will always generate a valid index

[ivory bobcat]

    void instanting(GameObject instantObject)
    {
        var position = new Vector3(UnityEngine.Random.Range(-384, 384), 512, UnityEngine.Random.Range(-384, 384));
        GameObject instance = Instantiate(instantObject, position, Quaternion.identity, transform);
        if (instantObject == radio)
        {
            instance.GetComponent<threeDimensionalAudio>().clint = players;
        }
    }```

[shell sorrel]

its max exclusive for ints

inclusive for floats

[graceful citrus]

yeah i got it

i read the docs 🤓

[rancid tinsel]

oh wait, for blockPrefabs.Length it will start at 1, but arrays start at 0 so therefore its always a valid index, do i understand it correctly?

[polar acorn]

Yes, the length of a collection is always 1 higher than the highest valid index in the collection

[shell sorrel]

length of a array is 1 higher then its max index, becuase random range is exclisive of max for ints, you can use it directly between 0 and length

[rare basin]

3 elements in the array meaning Count = 3, and the element indexes are as follow: 0,1,2

[graceful citrus]

can i make my terrain collider thicker

or, in general, can i make a mesh collider thicker

[polar acorn]

You shouldn't need to

[median ruin]

is

public bool State {
        get {
            return state;
        }
        set {
            state = newState;
        }
    }

preferred over

public bool GetState() {
    return state;
}
public bool SetState(newState) {
    state = newState;
}

or the otherway around?

[night mural]

colliders don't really have a 'thickness', they are a boundary line

[polar acorn]

Colliders don't have "thickness", they're always just triangles/quads

[rare basin]

it's preference

[graceful citrus]

if things go too fast, they go through the terrain

[slender nymph]

the top is just syntax sugar for the bottom

[ivory bobcat]

Semantics

[polar acorn]

Best:

public bool State {
  get => GetState();
  set => SetState(value);
}

Now you can do both

[graceful citrus]

i know, im just wording it as simply as possible

[median ruin]

I do like that

[polar acorn]

Change collision detection to continuous

[graceful citrus]

i understand that colliders do not actually have Collider.Thickness();

[polar acorn]

You'll just need to make sure GetState and SetState modify a different variable, like a private _state variable. Otherwise you'll have a recursive loop

[graceful citrus]

ahh

thats what thats about

[night mural]

you could alternately shoot some rays out and manually correct for it

[median ruin]

hmm... I see

[graceful citrus]

to confirm, with continuous detection, i can go at any speed and never phase through?

[night mural]

or up the physics step which is pretty low in unity by default

[polar acorn]

"never" is a big ask. You can absolutely go faster than the physics system can even track

[short hazel]

If your accessors do nothing else than getting/setting the backing field, you can use an auto-property instead.

public bool State { get; set; }

The two accessor methods are more the Java way of doing it.

[graceful citrus]

ok lemme rephrase: if i reach terminal velocity will i phase through

actually i have no idea if unity had terminal velocity

[polar acorn]

Depends on what your terminal velocity is

[median ruin]

Is there a downside to just doing

public bool state = false;
```?

[graceful citrus]

does unity not have a maximum fall speed

[rare basin]

but where do you pass the newState?

[graceful citrus]

actually drag = 0

[rare basin]

in the 1st option

[graceful citrus]

so in terms of physics, that wouldn't make sense

[polar acorn]

Without having either functions or a property, you cannot directly assign to the variable in a UnityEvent. There's other minor differences but that's the most readily apparent

[earnest atlas]

https://hatebin.com/nfzzgochqk

Somehow one momemnt inputs are null, next they arent null and like this on repeat. Whats going on?

[median ruin]

it's the idea that counts, the execution comes after

[night mural]

Your life will be much easier of you watch this and have an actual understanding of how the physics engine works. It's probably not how you are imagining:
https://www.youtube.com/watch?v=NwPIoVW65pE

[median ruin]

Hmm.. I see

[short hazel]

Kind of, if you ever want to modify what setting a new value does, with a property you change what's in the accessors, once. With a field you modify all 200 places it's being used
Prefer properties when exposing values outside of a class. It's C# standard.

[polar acorn]

My guess is you have two copies of this script and one of them has a null

[earnest atlas]

yeah found it

[graceful citrus]

yeah i just presumed it would use our physics

but i suppose coding that is more intensive than just getting pretty close

[polar acorn]

If we could code a physics engine that was 1:1 exactly like reality then we would no longer need physicists

[night mural]

even in scientific applications, they're just doing approximations (better ones, but still)

[bold wren]

can someone explain why unity is changing the unitystream.unity3d to unitystream.unity3d.tmp?

[night mural]

'i just assumed unity had implemented reality for me'
if only 😭

[slender nymph]

is there a code question here?

[graceful citrus]

exactly

i get it now

[bold wren]

oh my bad, where should i ask?

[graceful citrus]

idk what i was thinking about that

[night mural]

a better reason is that realistic gravity is not actually very fun in most games

[slender nymph]

id:browse to find a channel relevant to your question. and make sure to actually provide some details about wtf you are on about

[night mural]

and constraining yourself to it will make your life really hard

[graceful citrus]

i mean true

also that would involve simulation every subatomic particle

and if unity can barely run a couple thousand navmesh agents, it sure as hell can't run enough subatomic partles for anything visible to the naked eye

[earnest atlas]

The moment normal pc can run that optimization in code probably will go to second plan

Or compiler will do most of the job

[graceful citrus]

what is "second plan"

[carmine sierra]

hi i think I have an issue with this line, I dont see the sprite so could it be something to do with the camera's z position?

[graceful citrus]

im unsure the technical terms on rendering

[slender nymph]

you're putting the sprite at the same Z position as the camera so it ends up being too close for the camera to render
https://unity.huh.how/screentoworldpoint

[languid spire]

Amazing, you managed to output the word Clicked, yet completelyfailed to output the value of originalPos

[carmine sierra]

thanks so much

[carmine sierra]

still learning

[graceful citrus]

ok turns out unity is much better at handling things then i thought

i can spawn thousands of rigidbodies at little to no impact on performance

im chilling turns out

[languid spire]

when you debug output relevant information not just literals

[carmine sierra]

thanks for the tip

[eternal needle]

you definitely should have some performance impact at thousands of rigidbodies. Anyways if you need thousands of objects like this, unity gameobjects is not what you want to use

[graceful citrus]

well, its working for me

what do you suggest?

[eternal needle]

🤷‍♂️ i dont even know what you're trying to do. also "it works on my machine" is nice and all, until someone else runs it and gets confused how this game even got published when it runs at 2fps

[warm depot]

Hello, is it possible to create a game object outside of classes and then reference them inside classes?

[graceful citrus]

im just testing it

i have code intended to spawn 5 rigidbodies in random places but i felt the primal urge to turn 5 into 1000 and it surprisingly worked

[eternal needle]

what do you mean? and what are you trying to achieve?
creating a game object outside of classes makes little sense

[rough valley]

I have a problem, when I have one button it works normally, but when I have more than one, they both stop working

Can someone tell me why?

Or how to fix this

[carmine sierra]

should i make all GUIS UI objects?

[summer stump]

Can't really tell with that little detail

Is one button covering the other?

[rough valley]

No

[eternal needle]

well yea itll spawn and they can all sit there, sleeping. but try putting them all in the air near each other. They will absolutely destroy your performance when they all collide

[warm depot]

I have a game object called "cat", and I want to reference it in multiple classes without doing "public GameObject catObject;" in each class

[graceful citrus]

they all spawn in the air

and fall to the ground

[carmine sierra]

I used a gameobject since I didn't know how to code a UI, but if it is better overall I will use that

[rough valley]

The red button is the back button (back to main scene) and the "Upgrade1" for a upgrade @summer stump

[summer stump]

Can you show the inspector for each button?

[polar acorn]

which one doesn't work

[rough valley]

Both dont work

[eternal needle]

well some class is gonna have to reference it. Then other classes can reference that class who is holding the reference. Either way, you need a reference to something if you want to reference something

[polar acorn]

And if you delete either button, the other one works normally?

[summer stump]

The scaling and size seem messed up perhaps?

[rough valley]

No. Only the BackButton work

[eternal needle]

and all are colliding with each other? Use the profiler and see for yourself how the performance is. Also remember what i said above, it runs on your machine but if someone runs it and gets 2fps, they are refunding your game

[carmine sierra]

should all menus be UI's

[summer stump]

Are they an interface for the user?

[rough valley]

But just if I deleate the Upgrade1 Button

[carmine sierra]

yeah

[summer stump]

Then they should probably be a user interface

they can be worldspace ui if you want 🤷‍♂️

[polar acorn]

Can you select the Upgrade1 button and show a screenshot of the scene view to show what highlights?

[carmine sierra]

does that mean it would overlay a scene in the game

[summer stump]

No

[carmine sierra]

i should probably just learn how to use it

[summer stump]

you can have it overlay the camera if you want

[polar acorn]

Do you get any errors in the console when you try to run the game with both buttons on it

[summer stump]

you can have it be its own scene too

it depends on what you want

[graceful citrus]

they don't collide with eachother. they just hit the ground and roll

[carmine sierra]

I was just thinking it might be harder to reference but it shouldn't be right

[summer stump]

It will be exactly as easy or difficult to reference as anything else

perhaps easier, because UI usually exists before the scene starts

but not always

[rough valley]

So i just found a bug. for whatever reason the simulator starts the game in pause mode when i have 2 buttons, when i press play i can press one of the two buttons but only once after that i get the error "Object reference not set to an instance of an object".

[polar acorn]

So look at the line the error is on. Something on that line is null but you're trying to use it anyway

[carmine sierra]

i have a general question, as a beginner whos basically making multiplayer angry birds but with the barebones features, do you think a month and a half to complete it is do able

[polar acorn]

I wouldn't recommend doing multiplayer if you consider yourself in any way a beginner

[carmine sierra]

would it be something I can just slap on at the end

using mirror networking

[polar acorn]

absolutely not

[carmine sierra]

so what should I consider for multiplayer while im developing it

[polar acorn]

You shouldn't

[carmine sierra]

I need to though

[polar acorn]

why

[carmine sierra]

already written it up that itll be multiplayer

[rough valley]

And how do I fix this now?

[carmine sierra]

it will just be two players

room based network

[polar acorn]

you haven't said what the error is yet

[rough valley]

I did

[carmine sierra]

password to join a room

[rough valley]

Object reference not set to an instance of an object

[polar acorn]

So look at the line the error is on. Something on that line is null but you're trying to use it anyway

[summer stump]

The absolute opposite

If you develop the game for singleplayer and decide to do mp, you'll be rewriting most of your code (basically starting over)

At least huge chunks of it

[warm depot]

how would I get Destination over across these classes

[summer stump]

Make it a member variable (instead of local one in your method), and reference the class

Or make a public method on the bottom class and pass it in

[eternal needle]

then you've overscoped your project and should back away before investing more time. the sunk cost here is that you've only written itll be multiplayer

[polar acorn]

Destination exists only inside of the OnStateEnter function.

[frigid sequoia]

Just a tiny detail to have in mind on the future, when I am checking for stuff like... is something within the range of X; the if should be a < or <=; does this have any significant impact in performance or it doesn't matter?

[polar acorn]

Do you want it to check less than or less than or equal to

[frigid sequoia]

Is not really relevant, the differnece is nimial, that's why I am asking, cause I have found this case several times, and I don't know if I should be doing a <= when a < would do almost exactly the same

[polar acorn]

The only question to ask is which one you want to happen

There is no better or worse

just use the one you want

[warm depot]

Error CS8801 Cannot use local variable or local function 'Destination' declared in a top-level statement in this context.

sry, I'm a little confused

[frigid sequoia]

Ok

[ivory bobcat]

Maybe show what you've done

If it were me, I'd reference an instance of the other object and access a public member

[summer stump]

I'm not gonna be able to help with errors without code. The variable needs to be inside the class though, of course

[warm depot]

oo

what does a public member variable look like

[summer stump]

a variable in a class

[ivory bobcat]

It'd have the public accessor next to it

[polar acorn]

public Type Variable

[warm depot]

so it'd be like
public GameObject catObject;

[polar acorn]

probably

[warm depot]

and
public Vector2 Destination

but then how do I grab from the other class

[polar acorn]

https://unity.huh.how/references

[carmine sierra]

theres no better feeling than fixing a bug youve been working on for 2 hours

[warm depot]

getcomponent

[summer stump]

If it's on the same object, or an object you collide with or something, sure

[dull arch]

why is my asset fly up and falling down

[polar acorn]

Considering an asset is a file on a computer this is unlikely. Is your hard drive perhaps tied to several dozen helium balloons?

Do you mean an object in the scene?

[dull arch]

perhaps ill have to see

[dull arch]

yes

lol

[polar acorn]

Then either you've got code moving it up, your gravity is upside-down, or your camera is upside-down

[dull arch]

well my gravity is 3

no sorry 4

my camera doesnt look upside down

and i touched any script in this project yet

Is either supernatural or this is the biggest upside in history

[polar acorn]

Show the inspector of the object

[warm depot]

I'm lost on how to implement this

[polar acorn]

What is Destination and does it have a component named OnStateEnter on it

[dull arch]

I THINK MY CAMERA FOR SOME REASON IS GOING UP

[warm depot]

My best guess is this currently:
public Vector2 Destination = CatRoam.GetComponent<Vector2>();

I don't understand what fields I'm supposed to fill in with what

[summer stump]

Vector2 is not a component

[polar acorn]

Vector2 is not a component

[summer stump]

You would be getting CatRoam is FMState is a MonoBehaviour somewhere down the line

[summer stump]

I think you should perhaps stop and go through the courses here though
!learn

:teacher: Unity Learn ↗

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

[carmine sierra]

Question, is the trouble and time needed to learn how to make a simple two player multiplayer game not worth it? Should I resort to making my game pass and play despite it being a worse experience

considering a 6 week deadline

[shell sorrel]

why a 6 week deadline

that is very short even for experieced people to make a good product

[rocky canyon]

u probably wont have a multiplayer game done in 6 weeks

[shell sorrel]

you are still learning

[carmine sierra]

we started a few months ago, just recently we got to the development stage though

[queen adder]

multiplayer is easier than fading ui as one element

[rocky canyon]

use a canvas group..

[queen adder]

what were you doing the first months if not development

id recommend fishnet

i use pro

[rocky canyon]

why am i having dejavu?

[queen adder]

haha

look at the X reacts

[carmine sierra]

not much time spent on the coursework, just some analysing and designing

[shell sorrel]

you have been told about a few solutions, yes they require work to implement and have a few edge cases to work around but its all still very doable

[rocky canyon]

brainstorming / outlining stage prob

[median ruin]

How do you update navmesh via code?

[carmine sierra]

whats that

[rocky canyon]

do local multiplayer

[eternal needle]

The answer wont change from what we said above. Multiplayer is not easy. You cannot just add on the word "simple" in hopes it makes it easier. Making a 2 player game is the same as making a 3 player game, or a 4 player game. Even up to 10 players I would say has no difference

[carmine sierra]

yeah thats the plan

[summer stump]

Something that makes fading ui extremely easy

[carmine sierra]

room based connection

[rocky canyon]

local multiplayer is the middle ground between single player and multiplayer

ohh if its a connection its still technically full multiplayer

i mean 1 screen 2 players

[shell sorrel]

nah i will give them what they want is more complicated then toss a canvas group on it, but not has hard as they make it out to be

[queen adder]

[carmine sierra]

yeah, but is it that difficult to just connect players using a simple method like using a password to join another player

[rocky canyon]

ez sauce

[ripe shard]

Some people like to make ui harder than it is.

[north kiln]

The solution to use a render texture is still not difficult. If done correctly the performance is fine

[queen adder]

the solution with render textures taking up the entire size of screen negates performance by 2-3x, the other solution involves rewriting the whole ui system from what i was told

[eternal needle]

Again, #💻┃code-beginner message
You cannot just add the word "simple"

[rocky canyon]

i feel ya, but for <insert problem>, too

[queen adder]

you will have to learn networking concepts before you start

[unreal imp]

Guys, is there any way to do something like this? Is it about reducing the distance from where the bullet takes a collision with the forward of the crosshair? and also when it hits with that forward, the forward of the bullet will be the same as that of the crosshair. heres a cheap graphic

[carmine sierra]

what exactly makes it difficult, if you can explain to someone whos never made one

[carmine sierra]

how in depth

i know i want it to be a client-server connection

[summer stump]

Yes, a tiny bit more
But either way, they are clearly just trolling

[queen adder]

now try outlining the text, thick enough so that the outline of letters overlap, then do the same test.

[carmine sierra]

it will be hosted on one player's compute

[rocky canyon]

ya, i dont overlap my text..

[carmine sierra]

and the other player will just connect to it

[rocky canyon]

just simpler to avoid some problems..

by not creating them in the first place ;d

[queen adder]

maybe its integral to the games design

to have outlines like that on the text

and you cant just “not do it” to avoid the issue

[rocky canyon]

if it was then id still probably not do it.. i seen ur issue the other day.. try not using TextMeshPro/ overlapping text/ or maybe make a graphic out of the text and just fade the graphic instead

[ripe shard]

before you do UI in a game, learn what your UI framework is capable of and can do simply. Staring with a fancy idea that needs 100s of shims and extensions and complaints in a forum is a bad design.

[queen adder]

and you seriously post a gif of yourself changing the canvasgroup alpha like i dont know how it works…

[median ruin]

Why doesn't this work "NavMeshBuilder.BuildNavMesh();"? NavMeshBuilder doesn't seem to have a method called BuildNavMesh..?
I'm trying to rebuild the navmesh in a script.

[shell sorrel]

if its intergral to the game design, it should not be a big deal doing the work rendering to texture, or messing with the stencil shader

[queen adder]

the problem i guess is choosing a 3d engine trying to make a true-2D game

because unity uses meshes for everything

[eternal needle]

Everything. And in your 6 week deadline you said, you won't complete this in time. It isnt as simple as just connecting to another device and that's it, you need to think about if you want it to be client authoritative or server authoritative, both which have its difficulties. Common practices you see in beginner tutorials also no longer work (like making the player a singleton)

[north kiln]

I have to ask out of interest, do you have an example of a "2D engine" doing this correctly in real-time?

[queen adder]

godot and html5 canvas

[rocky canyon]

i posts gifs for almost every component i mention.. some people generally dont know.. i don't know enuff about u to know whether you knew or not.. if u did just scroll past it?

[carmine sierra]

alr ill take your word

[queen adder]

https://docs.godotengine.org/en/stable/classes/class_canvasgroup.html

[spiral narwhal]

How would I get a random Vector2 that is inside a collider?

[queen adder]

but godot 4 cannot export to web with C# backend yet

[north kiln]

It seems like they just have a render texture

[shell sorrel]

at this point you are not evne here for a soultion just to complain

[rocky canyon]

https://hamy.xyz/labs/unity-how-to-find-a-random-point-within-a-collider-mesh maybe this helps ya

[eternal needle]

I swear they solved it before too.. but this also isnt even a coding discussion

[rocky canyon]

i know u can use bounds and stuff for more primitive colliders i think

[summer stump]

Surprise surprise

[ripe shard]

you can just setup skia in unity and then write its buffer to a render texture

[queen adder]

what’s skia?

[ripe shard]

what all browsers use to draw 2D

might be a bit low-level, and you have to DIY the whole interactivity bit on top of that yourself

[queen adder]

i have an idea. a component you can attach to a ui gameobject. then it will calculate the bounding size of the object and all its children, create new canvas with camera render mode and camera rendering to a rendertexture of this calculated bounding box size. then it would replace the original element with a rawimage showing the rendertexture

could it be done?

i think there will be scaling issues

with mouse events but yeah

thats my current working idea

i just gotta make it

[rocky canyon]

if theres something about unity you dont like you can always make stuff for it..

then you can turn around and make an asset from it.. and make some monah 💸

[shell sorrel]

that was one of the suggested soultions

[rocky canyon]

cha-ching

[ivory bobcat]

MMO starter template 🥹

[queen adder]

i dont know about the cost of creating new separate camers and render textures for each set of elements i wanna do this for, but if the RTs arent full-screen maybe its cheaper

[carmine sierra]

this might be a stupid question but if I get a nullreferenceexception error when it should have occured, is it a bad thing despite the rest of the code still working?

[queen adder]

cameras in unity are pretty optimized tho, right

[ivory bobcat]

What's the code look like?

[shell sorrel]

you can likly share rt's if a full screen one, if there is only 1 or 2 things at a time that need this feature at once

[carmine sierra]

what would that change?

[rocky canyon]

if its a null error from your code you need to fix it asap

[ivory bobcat]

How we'd evaluate your question and concern.

[summer stump]

It would change us being able to answer or not...

[carmine sierra]

a bit more variables up top

[rocky canyon]

it'll tell us if the null error is a problem.. or if its a unity bug (that a restart) could solve

[queen adder]

hmm not quite sure i understand that. each element would need its own canvas+camera no?

[carmine sierra]

weapon instance gets spawned in by another code

[summer stump]

What is the nullref on?

[carmine sierra]

weaponinstance

[rocky canyon]

show console error

[queen adder]

anyways, the problem with scaling comes from moving the elements from the original canvas onto another one. it has to be at the exact same transform and the second canvas would need the exact same canvasscaler properties for it to work

[summer stump]

Then yeah, seems like it's an issue you definitely want to address

[ivory bobcat]

It's null. Determine why.

[queen adder]

im gonna work on a prototype

[carmine sierra]

but the code works fine anyways

i know why it's null

but do I need to change it

[summer stump]

Yes

[carmine sierra]

as it is working as intended

[rocky canyon]

a null error is bad

[carmine sierra]

just that it is also intended that clicking the object when weaponinstance is null won't do anythinhg

[rocky canyon]

it'll probably break ur code if thers any code running after the error

[summer stump]

That is an unnassigned reference error

[ivory bobcat]

Unhandled errors will ruin your game

[summer stump]

Not a null reference error

[carmine sierra]

so EVERY error, even expected and supossedly harmless ones should be coded out?

[rocky canyon]

if it could be unassigned then u should change ur code to react to that..

when it gets used.. check if its there first..

[shell sorrel]

if its a error it is not expected

[carmine sierra]

it is though

[rocky canyon]

if(weaponInstance){//now run code that uses weaponInstance}

[summer stump]

No such thing as a harmless error

[summer stump]

Then you should handle it so it is not an error

[short hazel]

Exceptions, as their name suggest, are exceptional. They should not happen during normal operation.
If one occurs, no code after it will be executed on the method for that frame

[shell sorrel]

they are called exceptions for a reason

[rocky canyon]

yup, ez fix.. change ur code around a bit to account for that possibilty

[carmine sierra]

ohh, so only that frame of the game would be ruined?

I will fix it though thanks

[summer stump]

No

At LEAST that frame will be ruined

[rocky canyon]

lol, very minimum

[carmine sierra]

i see

[summer stump]

If you see an error, stop everything you are doing and resolve it

[shell sorrel]

if something is aloud to be null and you dont want to use said thing if its null just null check it with a if statement

if its not to supposed to be null fix it

[short hazel]

obj.transform.position = Vector3.one; // let's say this throws an exception
Debug.Log("sample"); // this will NOT be executed

[rocky canyon]

^ so depending on when the error happens it can be minor.. or can ruin the entire script

[ivory bobcat]

Or other things on the stack that's being resolved as well

[rocky canyon]

the final goal is to have ur console appear like this 🙂

Debugs get removed from normal builds right?

[short hazel]

They get written to the player log file, IIRC

Which can slow down the game

[carmine sierra]

but lets say it would normally run like that but sometimes have an unassigned reference exception

[rocky canyon]

u need code to deal with it if it is

#💻┃code-beginner message

if(weaponInstance)
{
      //now run code that uses weaponInstance
}```

anytime theres a possibility it may be null.. and you're aware of that.. you need to make sure no code runs while its null

or no code runs that tries to use the reference that is null

[summer stump]

Then write code the handle that edge case

[rocky canyon]

this the same as if(weaponInstance != null)

[carmine sierra]

i always heard of that, an edge case is an error which sometimes occurs or what?

[rocky canyon]

like how raycasts are normally wrapped in an if statement.. if the raycast doesn't hit anything u dont want the code to try to do anything with the hit (which wouldn't exist)

[carmine sierra]

the error is gone nwo

[rocky canyon]

edge-case <-- a case that may happen.. even if it is rare

like an unlikely use-case

[carmine sierra]

oh thanks for the tip, i wrote the null one

[teal viper]

I think you're better off writing a custom ui shader or using rendering features(urp). It's gonna gonna be more performant than what I think you have in mind.

[rocky canyon]

im 100% in agreement with this statement ☝️

[short hazel]

Edge case is a possibility you didn't account for.
Example, you open a file to write to it, but didn't account for the possibility that the file is already in use by another program, throwing an exeption when you try to open a handle to it

[rocky canyon]

Render Features are 🔥

[teal viper]

@queen adder Though not ui, this sort of achieves the effect you want with render features using the stencil buffer:
https://www.fraculation.com/blog/overlapping-mesh-render

[queen adder]

thanks, im sorry for getting upset earlier. i just have no idea where to start with attempting that

[queen adder]

from the title this looks like exactly what i need

[teal viper]

Check the link above. It might give you a quick start and the ide of what you need to learn to achieve the effect.

[queen adder]

gonna look through it

thanks

[vague dirge]

I was wondering, my character can snap to a surface on input, as if it could stick to it, and I'm searching if it's possible to rotate also the Cinemachine camera orbits, as if the referencial was changing. Is there a way to achieve this ? Maybe it could be useful to have a way to edit the camera global axis ?

[rocky canyon]

i'd like to believe theres a setting in the component you can use to offset the camera like that

"dutch angle"

im not gonna get lying tho.. dont know nuff about it

[eternal needle]

Pretty sure cinemachine has a "world up transform" thatll allow you to do this

[rocky canyon]

oh ya that too, forgot about that tickbox

[vague dirge]

None of them seems working

Do I need to add some code maybe

[eternal needle]

Im on mobile so cant exactly show it, but I remember there being a field directly for the "world up transform". And you assign a transform in there

[vague dirge]

Okay thanks gonna search dat

Destroying assets is not permitted to avoid data loss.
If you really want to remove an asset use DestroyImmediate (theObject, true);
UnityEngine.Object:Destroy (UnityEngine.Object)

Why am I not allowed to use Destroy?

[eternal needle]

Did you read the message you pasted? you are trying to destroy an asset

[spiral narwhal]

I want to

[eternal needle]

Then read the message again and you'll learn how to

[spiral narwhal]

Read my message again

Why

Not how

[eternal needle]

Destroying assets is not permitted to avoid data loss.

[spiral narwhal]

But I've used Destroy a lot and that never happened :o

[eternal needle]

Because you are now trying to destroy an asset, a file in your project

not a game object in a scene

[teal viper]

You probably never destroyed an asset

[spiral narwhal]

private void DestroySelf()
        {
            foreach (var drop in _drops)
            {
                if (!Chance.Of(drop.Chance)) continue;

                var amount = Random.Range(drop.MinAmount, drop.MaxAmount);
                Enumerable
                    .Range(0, amount)
                    .ToList()
                    .ForEach(_ => ItemDropService.Instance.DropFrom(
                        transform.position,
                        PlayerMovement.Instance.GetFacingDirection(),
                        drop.Item)
                    );
            }

            if (!_destroyOnDeath) return;

            UnregisterSelf();
            Destroy(gameObject);
        }

That last line is the one

I thought that just destroys the object that has the script

[summer stump]

Can you show the inspector for that object?

[queen adder]

Just read through it and the idea seems right, its definitely what i want. But this seems to be for regular game objects, not UI, so Im struggling to see how to apply it to my issue

[summer stump]

Do you have a variable called gameObject?

[polar acorn]

It does. If the object that has the script is an asset (for example, a prefab), then you cannot destroy it

[spiral narwhal]

Ah

Yes it is a prefab

[polar acorn]

What calls DestroySelf

[queen adder]

And i understand the concept of the stencil buffer, i just dont know how to set it up globally on my ui

[spiral narwhal]

        public void Damage(int byAmount)
        {
            _hp -= byAmount;
            if (_hp <= 0) DestroySelf();
        }

So how do I destroy the object, not the prefab

[polar acorn]

Okay what calls Damage

[spiral narwhal]

A tool Scriptable Object

            if (_dealDamageToTiles)
            {
                var exists = TilePlacementService.Instance.PlaceableExistsAtPosition(roundedMousePosition);
                if (!exists) return;

                var tile = TilePlacementService.Instance.GetPlaceableAtPosition(roundedMousePosition);
                tile.Damage(_dealtObjectDamage); // <--- here
                ConsumeDurability(1);
            }

Basically whenever the player left clicks a tile

[shell bane]

Goodnight. I have a problem and I don't know how to solve it. When I click play to move to the next screen, it says there is no camera. Does anyone know how to solve it?

[polar acorn]

So tile is probably a prefab

[spiral narwhal]

It is

[polar acorn]

Can't destroy a prefab

[carmine sierra]

I don’t need anything spoonfed but how would you begin to go about creating an effect like this

[spiral narwhal]

I don't want to, I want to destroy it as if it were a normal object

[polar acorn]

Is there a camera on that next screen?

[polar acorn]

Which object do you want to destroy

[shell bane]

Main camera

yes

[queen adder]

Also, because this doesnt deal with actual shader code and just changes URP renderer data inspector settings, it isnt much helpful..:/

[summer stump]

Cache the click point on mouse down, calculate the distance and direction until mouse up

[spiral narwhal]

There is a prefab that has a DestroyableObject script on it.
That script has the Destroy method. Which lead to the bug

[polar acorn]

Show a screenshot of your hierarchy when you're on the screen that says there's no cameras

[polar acorn]

So what object do you actually want to destroy

[carmine sierra]

I can do that bit but I mean the effect

[queen adder]

isn’t the unity ui system render pipeline-agnostic?

[summer stump]

What effect?

[spiral narwhal]

The copy of the prefab

[summer stump]

*instance of the prefab

[teal viper]

Yeah, I'm not sure if that exact way would work with ui. Did you give it a try?
That's why I mentioned a custom shader with a stencil buffer, basically what this urp setup does for you.

[spiral narwhal]

helpful

[carmine sierra]

It would show a stretching triangular sort of shape (as seen in the photo) which originates at the slingshot ammo

[polar acorn]

which one

[summer stump]

It is an important difference. No need for the snark

[carmine sierra]

I was going to just make a normal slingshot but I’m having issues with the projectile motion if the weapon is pulled back

[summer stump]

Alter the vertex of a mesh based on the place the mouse is while held down

[carmine sierra]

Thanks 🙏

[summer stump]

Wait. Is it 2d or 3d?

[carmine sierra]

2d

[spiral narwhal]

So at runtime I spawn a bunch of these that all have the DestroyableObject prefab. And that DestroySelf method should destroy the spawned rock, not the prefab

[shell bane]

@polar acorn

[summer stump]

I am not great with 2d, but I think you could stretch a sprite renderer

[polar acorn]

So you would want to call that method on one of those objects, not the prefab

[polar acorn]

So, I don't see a camera in the Menu scene, meaning before Jogo loads it would be showing that error. Is that first screenshot before or after starting the game and attempting to change scenes?

[spiral narwhal]

Instantiate(randomPrefab.gameObject, transform).transform.position = targetPosition;

Is the instantion wrong? Because that's exactly what I intend to do

[summer stump]

Cache the result of instantiate

The destroy the cached object

[polar acorn]

Where are you storing the result of Instantiate

[spiral narwhal]

I don't

[polar acorn]

So then how do you intend to reference the object created by Instantiate

[shell bane]

first screenshot after starting

my game always worked normally, not what changed

[polar acorn]

So, if that's what the hierarchy looks like while the message is displayed, that would be the problem. There's no camera in that scene, at least none that I can tell at a glance is a camera

[spiral narwhal]

Ohhh I think I get it

Thank you

[shell bane]

If I add another camera, the error does not appear, and the screen does not change, it remains in the main menu

[dull arch]

can some explain what bool jump = false; mean compared to bool jump = true;

[frigid sequoia]

I cannot play an animation clip on command without an animationController right? There is no such thing as a .play for the animation component isn't it?
