[frosty hound]

For something to happen all the time, and to know when it should stop, something needs to check every frame.

[sharp solar]

in luau we would do it using signals, where Update would be a signal you can connect a function to, is there any similar concept in unity?

[frosty hound]

Whether you doing this yourself, or use some event system, is just a structural thing.

[polar acorn]

If you're not checking it every frame how is it supposed to know it shouldn't do the thing any more

[polar acorn]

if statements

[frosty hound]

Yes, signals in this case would be events I'd imagine.

But even that is still checking "all the time" under the hood. You just don't see it, which is probably why you feel better about it 🤷‍♂️

[sharp solar]

well an event happens when i want it to start and when i want it to end, and i would just connect and disconnect the function right?

[polar acorn]

You could invoke an event every frame, and just subscribe or unsubscribe from the event but null-checking an empty event and calling them is even more process intensive than checking a bool

[polar acorn]

The correct way to do this is to set a boolean and check it in Update. That is the least obtrusive and most performant way to do what you want to do.

[sharp solar]

damn

[polar acorn]

Every other ways is less intuitive and a higher performance cost

Checking a boolean is literally a single CPU cycle. It would take four billion of them to take up a second of processing time

[sharp solar]

signals are worse on memory but don't have to check every frame they just run through an array of connected functions every time they are called

[polar acorn]

Looping through an array is significantly slower than checking a boolean that many times

[sharp solar]

theres really nothing similar in unity?

[polar acorn]

Nothing faster than an if statement

[sharp solar]

wow

[polar acorn]

Why are you so fundamentally opposed to an if statement. It's the single most lightweight operation you can perform in code

[sharp solar]

so if statements are super fast in c#?

[polar acorn]

They're super fast everywhere

they map one to one with a machine code instruction

[naive pawn]

if statements are like 3 instructions

[sinful jewel]

Is it even worth nothing to do a complex FSM if the game (2d) is purely for practice?

[sharp solar]

idk cause in my head its code running that doesnt need to

[polar acorn]

If statements become je or jne

[sharp solar]

but if this is the way then i will do it

[polar acorn]

But it does need to, otherwise you wouldn't be writing it

[polar acorn]

You could use it to practice complex FSMs

[naive pawn]

well no they'd be a cmp + beq/bne

there would still be the cmp

[polar acorn]

Ah, right. Two instructions. Two billion if statements to reduce your FPS by one.

[naive pawn]

(im being pedantic, of course it doesn't matter)

[polar acorn]

Right, still a fair assessment

[sharp solar]

thank you for the help guys

is any kind of dt value passed to Update()

[polar acorn]

Time.deltaTime

[naive pawn]

no, it's accessible statically ^

[sharp solar]

thank you

is delta time constant in unity or variable

It is the amount of time in seconds the last frame took to execute

[sharp solar]

so variable

ok wait from a physics perspective should i be using this delta time value

or will a force mode of force resolve this?

[polar acorn]

For physics you should be using FixedUpdate and FixedDeltaTime

[sharp solar]

alright cheers

[spice mist]

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

[naive pawn]

@sharp solar fyi though - even though going through an array is comparatively slower than doing the direct check, it's still a tiny amount

let's say you have a 2 GHz processor that takes, idk 8 machine cycles for each instruction, being extremely generous
that's 4ns per instruction

an if on a bool would take 3 instructions - load bool, cmp, beq, 12ns
an if on an array would take 6 instructions - load array, load index, add, load value, cmp, beq, 24ns
plus like, 3 more for iteration, load index, add 1, set index, for +12ns

it's 12ns vs 36ns
at 10000 bools, that's 120us vs 360us - still far below a single frame, at 500 fps a single frame is 2ms

[naive pawn]

if you're using Force, don't use deltatime at all
it's applied automatically

[sharp solar]

thank you for this knowledge

roblox is such a letdown in almost every regard now that i've seen the light

[latent mortar]

Real🙏

That was my starting language

[latent mortar]

Where can I buy game

[sharp solar]

ive been on it for 4-5 years now and fed up when i ask for a simple bug fix after making them thousands of dollars just to get no response after months of bringing it up then when i say im fed up with not getting a response they remove my post

done

[latent mortar]

Wow 4-5 years is pure dedication

[thick spoke]

so i linked between the PlayerCamera class to the class named PotatoMovement(dont mind shitty names i am testing out random stuff). so i think i managed to call the functions correctly. but now i am wondering about the variables, like sensX and sensY. is it possible to add them in PotatoMovement and add SerializeField to them?

[sharp solar]

yeah cause i lied

3-4 years

i remember dates wrong

[latent mortar]

Still dedication

[fallow wind]

chat, i copied this from 5 different youtube tutorials, is this good?

using System.Collections;
using System.Collections.Generic;

sorry, i hit enter too quick

but its work

somehow

[latent mortar]

Don’t do yt tutorials trust me do thr Unity junior programmer tutorials

Otherwise you won’t retain the information as easily

[visual linden]

Looks perfectly fine. Is it working as it should?
One thing at glance is that Start can also be an IEnumerator directly. So you can do
IEnumerator Start and skip the StartCoroutine(DelayStart()); and just run your iterator directly

[thick spoke]

do you know what it does or how it works? if you do then its fine. just dont rely on them, since most of the time they are unreliable

[visual linden]

Nevermind I just saw the Update loop

What on Earth

[polar acorn]

Variables are not shared between scripts just because they have the same name. You could set the variables on your _playercam variable since they're public

[sharp solar]

with tutorials just make sure youre working toward something you want and youre not just observing you're trying to come up with your own solution as you go and it's fine

[thick spoke]

oh, dont mind my dumbass.

[sharp solar]

watching is bad, doing random tutorials is boring

[latent mortar]

The junior programmer one is peak it actually teaches u each common piece of code used in c#

[thick spoke]

i thought you meant it in smth else, like lets say my main class Player Camera i want to use it on multiple other classes/scripts beside PotatoMovement and i watch each of the other script to have a diffrent value for sensX and sensY. is something like that possible?

[polar acorn]

Are they all referring to the same instance of PlayerCamera

[thick spoke]

yes

[polar acorn]

Then there's one instance of PlayerCamera. It has a sensX and sensY, which will have whatever value they were last set to

int x = 7;
x = 4;
x = 12;
Debug.Log(x);

What do you expect this log to print?

It's the same principle.

[thick spoke]

Oh i see

Tysm for the simple explanation

[sharp solar]

what actually are classes

this is a new thing to me

[sour fulcrum]

what is an object for you in roblox

[sharp solar]

so same thing?

just a thing with properties and methods

[sour fulcrum]

short answer yes

[polar acorn]

A class is a blueprint for a thing. It defines the functions, variables, properties, etc. that an object can have.
You can create instances of a class to make an object that uses that blueprint. Those objects are individual elements of that class with their own copies of all of the variables and whatnot.

[sharp solar]

when i put a script inside a game object is it essentially creating a custom component?

component whos class is defined by the script

[polar acorn]

Like, a class is "The platonic ideal of Cat". It has variables for name and color and functions for DoMeow() and KnockShitOver(). An individual instance cat is named Ollie and is a Black Cat and when he meows it sounds like a smoker's cough and is an adorable bean

[thick spoke]

i am leaving google at this point, i had a ad tahts 3 minutes long and the video is 9 minutes... so a dd thats 1/3 of the video

[polar acorn]

When you add a component to a GameObject, it creates an instance of that class on that object.

[sour fulcrum]

ye, but just remember the component is an instance of that class/script, not directly the class/script itself if you know what i mean

[sharp solar]

yes

[sour fulcrum]

its a "component" because its inheriting MonoBehaviour which inherits Component which inherits UnityEngine.Object which is the base of class inheritence

[sharp solar]

so it goes without saying unity is very object oriented

[polar acorn]

Most modern programming languages are

[sharp solar]

is there types in c# or just classes

[polar acorn]

Types encompass classes and structs

Well, and primitives

[sharp solar]

can you make types

[polar acorn]

Yes, that's what you're doing every time you make a class or struct

[sharp solar]

right ok

so turning class code into a type is all automatic

[naive pawn]

no, the class is the type

you don't turn the class into the type

[sour fulcrum]

that response sounds like you might have a different thing relating to the term type

[naive pawn]

types include classes, structs, interfaces, enums, delegates, array types, primitives, and generics

[sharp solar]

a type to me is a thing that a variable is assigned so autocomplete knows what to do lol

[sour fulcrum]

i mean a type is just what something is

[naive pawn]

a variable isn't assigned to a type, a variable has a type

[sharp solar]

thats what i meant sorry

[sour fulcrum]

Someone smarter might disagree with this specific wording but its pretty much just an identifier

just so you can point your finger at an object and say "thats a human" / "i want a human here"

[naive pawn]

yeahhh so identifiers have a specific meaning

[sour fulcrum]

yeahh

identifier english wise

unfortunate overlap?

[naive pawn]

every time

[sharp solar]

in luau types are more of an optional thing that you use to assist typing out code which is where the confusion lies i think

[thick spoke]

quick question, is it possible to have sensX and sensY instances in PotatoMovement. privated, like if i ever edited the one inside of PotatoMovement. it doesnt affect any of the sensX and sensY outside of it? and could you provide a little example related to my problem if possible? if not possible its fine

[sour fulcrum]

yeee in most cases we are very explicit in what things are here

imo it's very preferable

[naive pawn]

types always exist - luau just doesn't have them (required) in source code

[polar acorn]

Every instance has their own copy of every variable

[thick spoke]

and how can i access them and modifiy them. cause i kinda forgot how(sorry 😭 )

[naive pawn]

...by name?

[thick spoke]

... how... i keep getting bunch of errors

[naive pawn]

what are the errors

[polar acorn]

using the name you gave them

[thick spoke]

or do i just write the entire thing

[polar acorn]

That's what the name is for

[naive pawn]

what "entire thing"

[polar acorn]

To serve as the thing you type when you want to use that variable

[thick spoke]

[SerializeField] float sensX = 5f;? should be like that or am i thinking wrong

[polar acorn]

So you would access this variable by name, sensX

[thin lotus]

how do I add a value to a list

[slender nymph]

.Add

[thick spoke]

so hopefully this is correct(prob not). so i went to the inspector and filled up the stuff. but those functions aint working, i am getting errors. i think those functions are still reading from main class instead of this instance, any ideas?

[thin lotus]

what .add?

[polar acorn]

What are the errors

[rich adder]

you never assigned a value to it. Hows the computer supposed to know which PlayerCamera you want to run those functions on

[thin lotus]

list.add?

yup, figured it out

[thick spoke]

i did that from the inspector, isnt that how it works?

[rich adder]

how did you do that in the inspector when the screenshot showed it was not even public or serialized

[rich adder]

also the error isnt even this script you showed

the error is on PlayerCam not PotatoMovement

[polar acorn]

What is the line the error is on

[thick spoke]

my sensX and sensY are public tho... including the oreintation

[naive pawn]

that's not what's erroring though

[thick spoke]

@polar acorn @rich adder any more information needed?

[polar acorn]

Which line is the line the error is on

[naive pawn]

also don't use deltaTime for mouse input, it's already per-frame

[thick spoke]

27 in the PotatoMovement which leads me to the earlier screenshot, the script i sent i believe its fine since i tested it

[thick spoke]

ah sweet, noted

[rich adder]

inside PlayerCam.cs

[polar acorn]

Line 27 of PlayerCam?

The line the error is on

[naive pawn]

wait, PotatoMovement is in PlayerCam.cs?

[thick spoke]

Exacly

i was gonna type that

[rich adder]

ruff

[naive pawn]

that's horrifying

[polar acorn]

Don't

[naive pawn]

welp, what nav said - you never set _playercam

[thick spoke]

i am testing so yeah, my code is really fucked....

[polar acorn]

Don't put two classes in the same file

[rich adder]

wow thanks unity for taking out the error of filename and component not matching..

[naive pawn]

no, "testing" should not result in this

[thick spoke]

its just 1 class... but i renamed it...

[thick spoke]

good point, after i figure out this last piece i will fix this mess

[restive kettle]

is there any lib i should import for random?

[thick spoke]

😭

[polar acorn]

UnityEngine

[cosmic dagger]

Unity has their own Random you can use . . .

[polar acorn]

Okay, so the file is named PlayerCam

[thick spoke]

i got like 5 playcam stuff so i needed to rename one so i can diffrenciate cause i didnt know what was the use of each one

[naive pawn]

it will tell you why.. its probably because you have the System namespace and its confused on which Random you want

[thick spoke]

yes and the class inside of it is potatoMovement

[polar acorn]

But the class is PotatoMovement

[thick spoke]

yes..

[polar acorn]

So then if that line you showed is that file, then _playercam is null

[naive pawn]

(they were redirected here)

[polar acorn]

Did you check what the error actually says

[thick spoke]

so this is wrong

[rich adder]

oh wops. didnt see those , had that person blocked for some reason lol

[naive pawn]

not necessarily wrong

[restive kettle]

i did rn mybad

[polar acorn]

Where do you assign a value to it

[rich adder]

so you lied

[cosmic dagger]

You should always lead with, show, and read the error . . .

[thick spoke]

oh... so i should use get component

[naive pawn]

you should do something to give it a value

[restive kettle]

thanks <3

[polar acorn]

You would need to actually assign a value to this variable

[thick spoke]

i thought we were talking about the values of sensX and sensY

[polar acorn]

you have to tell it which PlayerCamera you want that variable to hold a reference to

[rich adder]

those are value types, they don't throw null references... they are just numbers..

[thick spoke]

oh 😭

[naive pawn]

assign it in the inspector or use = to set it to something
that might be via GetComponent but we don't know your context to know if that'd be applicable

[thick spoke]

noted

[rich adder]

in most cases you want to do it in the inspector

[naive pawn]

-# well to be pedantic reference types are also numbers

[rich adder]

truth

[thick spoke]

could you give me a quick example on how to do it so we dont spiral down on another maze

[thick spoke]

noted aswell

but i will try to do it via script

[rich adder]

look up the method they suggested, in the docs then

freebie on the house
https://docs.unity3d.com/6000.1/Documentation/ScriptReference/GameObject.GetComponent.html

[rich adder]

here a neat GIF too from unityhuh site

[thick spoke]

i meant inside of a script, the get component one 😭

[polar acorn]

Is the component you want on a different object

[thick spoke]

no its just this, but you said if i did it using the get component way correctly my problem would be magically solved since i wasnt instantaiting correctly

so like this?

[polar acorn]

What object has the PlayerCamera you want this variable to reference

[naive pawn]

instantiation doesn't really have anything to do with this

[rich adder]

have to start taking chances as a dev and things on your own

[thick spoke]

i didnt get it....

[polar acorn]

This variable is a box. The box has a label on it that says "For FirstPersonMovement.PlayerCameras ONLY! 😠"

You have to actually put something in the box. Which FirstPersonMovement.PlayerCamera do you want to put in the box

[thick spoke]

i mean... i dont know what exacly to put inside of it

[polar acorn]

Which PlayerCamera component do you want to reference

When you call _playercam.MouseLocking(), which PlayerCamera do you want to call MouseLocking() on

[rich adder]

https://youtu.be/Z0Z7xc18CcA

[thick spoke]

the instantiated one

[polar acorn]

Where are you instantiating it

[thick spoke]

hold on let me watch this so i can understand without asking too many questions

[thick spoke]

Playercam Script...

[polar acorn]

Show where you're instantiating it

[thick spoke]

FirtPersonMovement.PlayerCamera _playercam;
_playercam = GetComponent<PlayerCamera>();

...wrong?

[polar acorn]

None of these are instantiating anything

FirstPersonMovement.PlayerCamera _playercam is creating a variable that can hold a FirstPersonMovement.PlayerCamera.

_playercam = GetComponent<PlayerCamera>() is setting the _playercam variable to the PlayerCamera component on this object.

Does this object have a PlayerCamera component on it

[exotic forge]

and I think instantiating is probably not what you want to do anyway. iirc, instantiating would be to create a gameObject from a prefab that the script sits on. Get component would pick up an existing one off the same game object. new() would be to create an instance of a class that is not a monobehavior. and for monobehaviours... i can't remember the syntax, but there's something like AddComponent<>(). I think

[rich adder]

slight correction, instantiate doesn't need to be with a prefab.
in unity it just clones an object basically

[exotic forge]

but in this case, I think what you'd want is to add the PlayerCamera script to the game object in the editor, then use a GetComponent call in PotatoMovement to set your _playercam reference variable

[exotic forge]

ty ty

[polar acorn]

I think they don't actually know what "Instantiate" means or what an instance even is so I don't want to start going into solutionizing until they've actually managed to sus out what it is they actually want to happen

Otherwise it's just going to get confusing.

Chances are, they do want to do this, but at this point we aren't actually sure what the intent is

[exotic forge]

mhm. fair. I'm just hoping to lay out some definitions at least to help clear things up

[polar acorn]

I'm not sure if they're trying to add a component or reference one that already exists

[thick spoke]

oh... i see, i think i got a idea on what to do

Hi Guys,
Does unitywebrequest work like coroutine and on main thread? I have to download 6-7 glbs . Not sure if i should use c# native httpClient or unitywebrequest.
I heard UnityWebRequest is executed mainly on main thread.
Dont want to make the game stutter during the downloading (i dont trust coroutine based behaviour for performance while downloading large files paralley)
If i can offload the download to other threads then all good

[exotic forge]

for my web request, I was just using Task / Await which is on the main thread, but it's not a giant download like that, so I can't say how that would go...

as far as I know, the job system is the only multi thread option in unity, and it doesn't talk all that well with the main thread, so i'm also not sure how handing over 7 gb as a return type would go

[vale turret]

sorry, its not gb i mean glb format

[exotic forge]

ooooo

my bad my bad

[vale turret]

total around 150mb max

If i couple HttpClient with UniTask then will that be better?
I feel unitywebrequest use coroutine under the hood.

[rich adder]

no

[olive lintel]

Hey guys, sorry for the stupid question but I'm trying to write a simple function to convert a position from world space to local space in a simplified way that assumes the local space of a logged transform always has a y and z axis rotation of 0. The problem is that I'm having alignment issues with the results and I honestly have no idea how this is happening. It's almost like its assuming the angle of it is slightly off?

    {
        Vector3 localPos = worldPos - origin;
        Vector3 flatPos = localPos;
        flatPos.y = 0;

        return right * flatPos.x + forward * flatPos.z + new Vector3(0, localPos.y,0);
    }

Here's a clip of what isn't working. The Cyan Sphere is the base/anchor transform, and I'm trying to convert the yellow spheres position to its local space. The green line is drawn between what the function above is returning to me and the yellow spheres position.

Any help is greatly appreciated, thank you

[shell kernel]

For probably easy problems with code i just post the code here?

[rich adder]

webrequest is optimized for unity, read somewhere a while back that it was threaded

[eternal needle]

https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequest.SendWebRequest.html

returns a WebRequestAsyncOperation

[exotic forge]

nice

[rich adder]

sure but shouldn't be a replacement for google which what a lot of people do

[exotic forge]

you may be overcomplicating this. is the yellow sphere a child on the anchor? or is it a spawnpoint for future children of the cyan sphere? in most cases you could just take transfrom.localPosition. outside of that, there are prebuilt functions for converting worldspace to local and back

https://docs.unity3d.com/6000.1/Documentation/ScriptReference/Transform.InverseTransformPoint.html

[olive lintel]

it's intended to be used in a lookup table for culling optimisation purposes, this is a simple test of the function to make sure it returns the correct value

[shell kernel]

probaly i will find a solution on youtube or google , but I dont even know the problem

[olive lintel]

I was originally using InverseTransformPoint but I realised I could make optimisations to cull unseen building faces

[exotic forge]

ah ok. in that case

i will look a little closer at your snippet

how are you passing in right and forward?

it concerns me that your green line moves when you rotate the cyan sphere

[rich adder]

what is happening vs what you expect to happen ?

[shell kernel]

I want that that button moves my triangle, and it worked, until I added mirrow and suddenly it stoped working

[exotic forge]

mirrow?

[rich adder]

what is mirrow

[shell kernel]

Oh mirror

sorry

[rich adder]

you're doing multiplayer ?

[exotic forge]

also you never use the entirety of flatPos, so you don't need to set its y component to 0. in fact, you could just use localPos

[shell kernel]

i am trying to

[olive lintel]

I don't know why, but instead of using the anchor transforms actual transform.forward and transform.right, I create a rotation Quaternion.Euler(0, -anchor.EulerAngles.y, 0) and use the Vector.forward and Vector3.right of that and it works now

just switching the Y angle of the anchor seems to have fixed it?

*or flipping it

[rich adder]

you're in ⁠code-beginner asking about multiplayer lol Should you be doing that already?

[exotic forge]

no it's thedifference bertween using transform.right and vector.right

if you comment out he quaternion line, the second one should still work

[olive lintel]

the second one does, the first doesnt

[exotic forge]

yeah

[olive lintel]

wouldn't testAnchor.forward be the same as testAnchor.rotation * Vector3.forward?

[shell kernel]

I know how to code, but I'm learning unity new. I don't know how thinks work with buttons, prefabs, skrips,...

[exotic forge]

ohhhh, I see. maybe. huh....

[rich adder]

thats like the most essential part about doing a multiplayer part here..

[olive lintel]

I have no idea why it works

it makes literally zero sense lmao

[shell kernel]

well ok..

[rich adder]

no one can help if you're asking
"i add package and is broke "

[olive lintel]

and using -testanchor.forward and -testanchor.right doesnt work either so

I have literally no idea why

but it works...

[exotic forge]

just out of curiousity, if you only pass in vector3.forward / right without the testRot, what happens?

[olive lintel]

completely boned again

cause its basically assuming the transform has a rotation of Quaternion.identity

[exotic forge]

huh. lol. i'm gonna have to think on that

lots of pieces in play, here

[golden thorn]

unity is wholeheartedly convinced that there is a missing script on this object, when it is most certainly there. no other objects named door exist in my scene, and this is the only script the door is trying to reference

anyone have an idea of why it might be doing this?

when i click on the script name in the component area of the object it highlights the correct script in the project area, meaning it definitely knows its there.

for context, this started as a prefab from the asset store. I removed the old script component on the door, and added a new script component with my own script. It seems like it just wont forget about this deleted script component

[gleaming jewel]

i hate unity

its hard asf

im thinking about giving up on game dev

what should i do

[frail hawk]

what do you find so hard?

[hexed terrace]

delete all those messags from here, and stick to #💻┃unity-talk

yaya098009 has been warned.

[void thicket]

It says referenced script. something else is referencing old component of yours

[polar acorn]

Can you show the full inspector of the Door object?

And also the prefab

[golden thorn]

here is the parent object (door_1_venge) and its children

it is definitely something within this parent/children, i just dont know where

[polar acorn]

Well, this is Door_1_Venge. The error says it's on an object named Door

[golden thorn]

door_1_venge is the parent of door.

[polar acorn]

So show the inspector of Door

[golden thorn]

i did

the inspector of door is in those images, its the 2nd and 3rd

[polar acorn]

Oh, there's a lot more images than thumbnails, I didn't scroll far enough, my bad

[golden thorn]

no youre fine, sorry for the image spam there lol. i know discord doesnt make it easy to see

[polar acorn]

Well, this Door object looks to be fine. Is this the prefab, or an instance of it in the scene?

[golden thorn]

may as well add - this is the tree for it

[golden thorn]

so im pretty new so ill describe what i did and hopefully that answers the question.

I dragged this prefab onto the scene from the project area, i deleted its script on the object in the scene, and then added the component for my script

[lime sigil]

heyo i'm working with gltf to load a model into the scene

    private void Import_GLTF()
    {
        string dir = "actual/folder";
        string filename = "file.gltf";

        Uri uri = new Uri(dir);
        string uriString = uri.AbsoluteUri;

        var importOpt = new ImportOptions();
        importOpt.DataLoader = new UnityWebRequestLoader(uriString);
        var import = new GLTFSceneImporter(filename, importOpt);
        Task gltf_import = import.LoadSceneAsync();
    }

this goes on in the background without await so it doesn't stop the user while it's loading even if it's a big model

how would i exactly get the percentage complete from a task?
i can't cast it to Awaitable or Addressable to get that value, how could i approach this in general?

all i could find uses awaitable or addressable and can't cast to either

[polar acorn]

Okay, so the screenshot was of the instance in the scene. The Prefab itself might have the missing script. Open up the prefab and check there

[golden thorn]

ah it does, so if the original prefab relies on that script, i will get the error even if i removed it on the instance in my scene?

[polar acorn]

Something is likely still looking for that script which no longer exists. If you're removing it from the prefab every time you spawn something, you should probably just not have that script on the prefab in the first place

[golden thorn]

yeah so far this is just the initial drop of the door, so i was testing things before making changes to the prefabs themselves

lemme see if this fixes it

that did, appreciate the help.

thatll be an interesting hill to climb when i end up in a situation where I need a one off on a prefab with a different script lol

[polar acorn]

The issue isn't that the prefab has a script that the instance doesn't - it's that something is still expecting that script to be there

So, something else is referring to that script, probably within that prefab

[shut swallow]

How do I save player's level completion time and load it in the main menu?

[cosmic dagger]

You need to store data by saving and loading to a file . . .

[eager scarab]

extremely new to c#, this is the way i was able to make movement but with the addforce thing itll just keep on adding up and build momentum until like infinity pretty sure, so is there any better way i can learn to do this?

to any ppl experienced in coding with unity this codes prob gonna look really bad lol

[ivory bobcat]

Are you wanting non RB movement?

[eager scarab]

just any sort of movement

i was originally gonna change the co ordinates every frame but i just messed around with rigidbodies instead

[ivory bobcat]

If you're wanting to use RB for collision detection the common choices are to:

• Move using velocity (6.0: linearVelocity)
• Kinematic RB (create your own physics but still have some RB features - moderate to difficult)

[eager scarab]

i originally tried it with velocity but for some reason it wouldnt move when going to the side, im assuming it has something to do with the colliders

bad code space program (spamming space)

[green crater]

Hello I need some help. I am a total beginner with some coding background but still very much a novice. Trying to add a player movement script to a player object as a component while following a guide on yt. I keep getting this error "Can't add script behaviour 'PlayerMovement'. The script needs to derive from MonoBehaviour!" and am not sure how to troubleshoot.

[eager scarab]

i think u made a non monobehaviour script

if u made one it should show in brackets on the name in inspector

[green crater]

So one thing with this version of unity is there are a bunch of options in the create > script options and it was confusing. I chose "empty c# script"

[eager scarab]

yea ur gonna wanna click this one

[green crater]

Ah okay I will try that, thank you very much

[shut swallow]

if I wanna save data in relation to a specific scene (e.g. time on stage 1), would it be better if I use dict or using two lists?

[ivory bobcat]

Maybe something like this would suffice for horizontal movement and a jump mechaniccs float x = 0; if(...)//Right held x += 1f; if(...)//Left held x -= 1f; var velocity = rb.linearVelocity; velocity.x = Mathf.Clamp(velocity.x + x * speed * deltaTime, minSpeed, maxSpeed); rb.linearVelocity = velocity; if(...)//Jump rb.AddForce(jumpForce, ForceMode.Impulse);

[brave robin]

Dictionary can't be serialized as-is, so if you play on saving it to JSON or some other format then you'll have to do it as two lists (keys and values), or saving the key-value pairs as structs

[shut swallow]

I'm currently following this (https://www.youtube.com/watch?v=XOjd_qU2Ido), would it be better if I do it in JSON and pivot now or is the tutorial still fine

[brave robin]

I suspect the tutorial is fine, but I don't have time at the moment to watch it all

[shut swallow]

ah ok, it'slike a 6y/o tut, and it made no mentions to JSON so i was a bit confused

[brave robin]

JSON is just one possibility, you can save in many other formats
Just don't save to playerprefs

[shut swallow]

Oh yea I heard about that
First piece of advise of saving "NEVER USE PLAYERREFS" which i heard in some video, pretty funny

[stuck field]

PlayerPrefs is fine to use for some saving that isn't a big deal, but most save data, you should avoid it

By itself though, not a great utility, if you build a parser for many types and use that to save to playerprefs for non-trivial data, then it's fine

[brave robin]

It has one downfall of being messy. You can always delete files you save in most formats, but playerprefs goes to your registry which is not as simple

[stuck field]

Yeah, definitely more messy, not a preferable option

[eternal needle]

it most definitely can be serialized as a dictionary @shut swallow
https://www.newtonsoft.com/json/help/html/serializedictionary.htm

[brave robin]

Guess that's a new addition since I last looked, as a few years back everyone was writing their own serializable dictionary substitutes that were two lists or structs under the hood

[rancid rose]

I am looking for some pointers on the most appropriate way to avoid my player (rigidbody) getting stuck on walls in my 3d scene. I've tried setting the walls friction and bounciness to 0, and this has stopped my issues with getting stuck, but has introduced weird movement with steep slopes where the player is able to walk up slopes they definitely shouldn't be able too. Is there other solutions to the problem that fix the player getting stuck on walls without breaking slope movement?

[wind hinge]

How do you make a custom cursor with special vfx without it lagging behind?

[shut swallow]

FindObjectsOfType<MonoBehaviour>() how do I rewrite this with the new FindObjectsByType, I just replaces Of to By and it didn't work

what do I pass as object?

[shell sorrel]

looking at the docs you need to pass it the sort mode to use

FindObjectsSortMode.None

[shut swallow]

what's the syntax, I'm reading the api and still a bit confused

[shell sorrel]

pass the type as a generic so in the <>

[shut swallow]

I still don't really get it sorry, elif

[shell sorrel]

FindObjectsByType<MonoBehaviour>(FindObjectsSortMode.None)

[shut swallow]

I thought type needed to be declaired within the method

[shell sorrel]

it supports both

but using generics is better since you get the proper return type without a cast

to pass it as a args you need to use typeof

FindObjectsByType(typeof(MonoBehaviour), FindObjectsSortMode.None)

[shut swallow]

any reason to use args over the generic?

[shell sorrel]

for 90% of cases or more no

use the generic

[sour fulcrum]

weird and probably unideal situations where your passing through a type via a param/value and can't explicitly define the generic usage

[shell sorrel]

doing it via args can make sense in some edge cases

like if you got a type via reflection

for most cases if something needs a type and supports generics use that over passing it as a regular arg

[sour fulcrum]

Also not directly saying don’t do it that way but findobjectoftype calls are pretty heavy and iterating through every monobehaviour conditionally casting is probably not great either at scale

[shell sorrel]

99% chance you are better off doing the reverse of this, having those objects call a manager and pass themselfs to it

[sour fulcrum]

And if for whatever reason these objects toggle their gameobject activity that search won’t find them unless you specify in the findobjectsoftype param that you wanna find inactive objects

[shell sorrel]

then you get a collection that only contains stuff you care about without searching every component in the scene

[sour fulcrum]

Though there's not particually a great way to do this in the scope of the interface right?

I guess that's somewhat by design but

[shell sorrel]

my suggestion would work with components that implement the interface just fine

[sour fulcrum]

fair, i just meant that the component has to explicitly handle the giving that out

[shell sorrel]

yeah its that or searching alot of objects

i very commonly have things that on Start will notify other systems about themselfs oftne just calling a method and passing this

and due to covariance it will work even if its accepting it via interface

[sour fulcrum]

yeah same. I think i keep wanting interfaces to do stuff there not meant to do and i get dissapointed when they cant aha

would be "nice" to get a interface function running on object creation without needing the thing implementing it to "manually" call it

[shell sorrel]

they do most things i want, only rubbish part is not working with SerialzeField

but i also don't really use components unless i have to, so a lot of systems are just regular C# with regular objects

[sour fulcrum]

i over-use default implementations but one thing i would really like is a way to override default implementations from a inheriting interface

[shell sorrel]

yeah i do not use default implementations for the most part, feels like fighting what interfaces really are

[sour fulcrum]

probably

[shut swallow]

idek what's an audio listener, how do I solve this

[sour fulcrum]

usually they on cameras iirc

[queen adder]

it's a component to listen for audio, check your cameras for it because that's where they usually are at

[rancid rose]

for anyone else with a similar issue, i was able to solve it by keeping the friction at 0, and raycasting near my players feet in the direction they are moving, if the angle of the object they are moving into is greater than my max slope angle i disable movement in my movement controller. Now if a player lands on a slope they slide down it.

[wind hinge]

Still wondering! Thx

[rich ice]

depends on what you mean by lagging behind

and special vfx

assuming it's just an image then just setting the image's position to the mouse position in update should work fine (i dont think it'd lag behind a by a frame but im not 100% sure)

[sharp solar]

is garbage collection automatic in c#

[rich ice]

i've never worked with garbage collection but this might be a good place to look

[sharp solar]

why does unity have to use quaternions 😢

3x3 matrix is so much awesomer

[rich ice]

it's to stop Euler locking

reminds me i also need to look into quaternions some more. i still barely understand them

[sharp solar]

im hoping through functions i wont have to understand them lol

[formal tide]

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

I finally added 5 second cool down after using jump

[sharp solar]

is there any difference between Awake() and Start()

[formal tide]

Awake has priority on execution order

I learned this today 😁

[sharp solar]

can you access unity hierarchy through a script during runtime instead of setting public variables beforehand

[rich ice]

the more you know :D

[rich ice]

not sure, usually you'd just use one of the many Find~ methods to get the object you're looking for

[sharp solar]

oh ok

[formal tide]

Now i wanna learn how to connect different scripts and use methods from anothet script

But i dont wanna push too fast. tho i should practice what i learn recently

[rich ice]

usually you'd have a script as a component on an object and then you could reference the script in the editor by passing in the component.
i discovered UnityEvents pretty recently though and they've been so useful (UnityEvents my beloved)

[rich ice]

oh yeah that's fair. learning at your own pace is always best

[eternal needle]

you generally dont have to worry about the gc yea.

[eternal needle]

these are questions you can easily google. this channel is more for questions you're actually stuck on rather than a replacement for google

[sharp solar]

true

[formal tide]

Chatgpt deepseek and unity documentation manual scrip page

U can learn everhthing with these 3

Just be aware that ai can give u wrong answers sometimes

U need to check documentation first then ai to see the end of tha road mate

😁

😧

[sharp solar]

❌

[formal tide]

I learned everything with tha ai and unity documentation bruv

[sharp solar]

yea

[formal tide]

I tried youtube and udemy but it didnt worked for me

[sharp solar]

youtube sucks

u learn how to make the thing they are making but u dont learn how to use unity

(that was my experience with roblox lol)

[formal tide]

Sometimes works. If i didnt understand with ai and documentation i go google and youtubr

Last chance

[sharp solar]

AI is pretty cracked nowadays

wasn't really a thing last time i had to learn something

[formal tide]

Yep.

[formal tide]

I just learned basic language syntax and i asked ai and copy paste code blocks and edit it like that until i solve the issue

Ai doesnt give me the full answer most of the time on coding

I have to edit it

But ai shows u the road very well

About which techniques u should use

Maybe im wrong but i feel like it works 🤣

[glad ibex]

Ai is good for learning unless you just mindlessly copy and paste

[formal tide]

At least it gives me the different solutions and see the different routr

Route

[formal tide]

Yeah

[sharp solar]

just dont ask AI to write you the code

boom

[eternal needle]

all pretty bad advice tbh. if you want to read/comment on the use of AI, there is a forum https://discord.com/channels/489222168727519232/1352599815770341479

a bunch of beginners telling each other AI helped them learn definitely isnt the best advice you want to be reading from.

[sharp solar]

am only a beginner to unity***

[formal tide]

I tried udemy youtube those were the worst than ai for sure

I rather use ai than a university student acting like he is computer engineer professor

[eternal needle]

yet i never suggested udemy or listening to these university students. dont suggest others to use AI at least. It's highly discouraged here

[ivory bobcat]

A couple of reasons why AI isn't good to learn from:

• It makes mistakes that you may be unaware of
• It uses strange patterns and do not really understand what it's doing
• It's convincing
• It lies
• Dependency issues
  A couple of reasons why AI might be useful:
• Pretty up code you've already written (documentation, syntax etc)
• Draft prototypes that are tedious to write
  Personally, I'd use it like a work horse to brute force simple tedious tasks.. if anything.
  It's not very fun to fix mistakes that aren't relevant and can lead a beginner down the rabbit hole if they aren't aware that it's wrong/lying.

[burnt vapor]

While I would agree with you I really would not recommend AI at all when it comes to beginner programming of any scale

It takes a specific mindset to actually learn from AI, and most people don't have it in them to actually understand what is written and how it is written, especially here.

And also because it can be confidently wrong, meaning you need to ensure that your knowledge and/or research skills is good enough to understand if the code is good

[eternal needle]

It's all too common where a beginner will see any positive feedback about AI and decide to continue using it for everything regardless of how many negatives you list.
Though the worst is the case above where a beginner who clearly started recently says they learned everything through AI. "Everything" being very misleading when they said they don't know how to reference another script.

[formal tide]

i recommend ai

even professional coders uses it

no need to avoid it

its useful sometimes but yea it can give u wrong answers

[eternal needle]

repeating points while not addressing the responses isn't going to go anywhere. plus i truthfully dont care to convince you otherwise at this point
Dont take it from me then, mods have given the same advice about not suggesting people to use AI
#1319020501250740315 message
#archived-game-design message

[formal tide]

well i just told u ai and unity documentations helped me alot

and i told you that ai can give u wrong answer and u need to edit it

[eternal needle]

Yea you clearly arent reading what I'm writing if you're still just repeating stuff you said from above.
I'm done here

As i pointed out above, there is also a forum for AI discussions

[formal tide]

is it forbidden to recommend ai

[rich ice]

it's a debatable question. AI is still a very new thing and it's still at the point where it's improving by the day.
imo it's just down to personal preference although solely relying on it is definitely going a bit too far. using the general standard is usually the safest bet and thus the only one you can really recommend.

[formal tide]

yes i agree

[eager spindle]

yes, this discord server is for learning and AI is not good for learning at all. people who use AI for learning will lean in to just having AI code everything for them, and they won't develop the skills to research what they're looking for and debug code, the most important parts of being a developer

when you go out to work you realise that you won't know everything, and you'll be using libraries that just have next to no documentation. your AI won't be able to help you anymore and you're expected to live without AI

[formal tide]

im using unity doc ai youtube google

[eager spindle]

and yes I've had to personally guide colleagues who are like this

[sharp solar]

this is a silly conversation

[eager spindle]

it's actually painful

let's not promote AI here at all

[formal tide]

i dont wanna work as a coder tho. i just wanna make my own small game

[eager spindle]

so you don't wanna learn coding and just have us debug for you

[sharp solar]

people here are going to naturally gravitate toward pro AI or anti AI mindsets and whether you should or shouldnt use AI is highly opinionated. just do what you want, it's a tool, no need to push your beliefs onto others

[formal tide]

well im just started learning coding

[formal tide]

i agree

[burnt vapor]

Your experience with AI is not the same as what others will experience. Beginners resort to being spoonfed answers very frequently and especially AI is a problem as it will give a lot of code with possible errors that just resorts beginners to come back here and ask what's wrong with it.

[eager spindle]

if you don't work in a programming role then ok I guess but just try to understand what the AI is giving you

[burnt vapor]

We're not against AI, we don't need people suggesting AI to beginners because it won't work for them

[eager spindle]

this channel has been flooded with people asking us to debug their AI generated code

[formal tide]

in my own experience. i tried to learn coding in the past too much and i always failed and i gave ai chance and i liked it with the help of unity documentation

[north kiln]

I'd rather eat bricks personally, but you do you

[eternal needle]

And also flooded with beginners spitting out the exact same talking points while barely reading the actual responses.
Ive directed to the ai discussion forum twice already lol

[eager spindle]

It's just not nice to ask other people to fix code when the person doesn't even know the fundamentals of coding

[formal tide]

yeah. it gives wrong answers most of the time and im searching on the internet to find correct one

[burnt vapor]

Which is what beginners do not do

[eager spindle]

AI isn't good at debugging imo, like you tell it "oh I experienced this error please help" and it will not help you to fix it

[burnt vapor]

They come here, often after many failed attempts of editing the code and making it worse

[north kiln]

If someone says they used AI and have come here for help it's a great invitation for me to do something worthwhile elsewhere

[formal tide]

i dont copy paste code without understand it. im searching on unity documentation youtube google to see if its logical

if its logical i copy paste it

[eager spindle]

That's good

Do try to understand the code along the way

[formal tide]

for sure

i analyze codes that ai recommends

i should give disclaimer before

[sharp solar]

well "using AI to write code that you don't understand, then make it worse, then get someone to fix it for free" is objectively a terrible thing to do but in my opinion using AI to learn stuff is fine

[eager spindle]

Happens in this channel daily

[fickle plume]

@formal tide Trying to learn from pre-chewed responses of LLM is very counterproductive. By not looking up things in documentation and using structured courses you are severely handicapping yourself.
But that's up to you.
Here, like you've been told already, don't send people to AI or talk about it really, it's off-topic.

[sharp solar]

pasting a block of code and saying "fix it" is annoying in general in my opinion

this happened before AI too

[formal tide]

i never said i dont look up thing in documentation sir

i use all of em

jesus

[fickle plume]

Then drop it already

[formal tide]

i didnt know ai was hot topic like this

[rich ice]

in this guy's defence, they have said a few times that they've been looking up documentation to double check.
they have actively been reading any documentation that's been shown to them in this channel.
they seem to be getting dogpiled a bit here due to how controversial the topic is.

[sour fulcrum]

more specifically the dogpilling was more so in response to the endorsement of ai rather than acknowledgement of usage

[golden obsidian]

it's not hot topic, but abusing AI without learning from it might get you no where, at least thats what people here is trying to say, I guess...

[sour fulcrum]

its a hot topic

[eager spindle]

and more that the user is suggesting that beginners can rely on AI to teach them things without developing developer skills is a bad idea in general

[visual linden]

Most of us here are volunteering our time helping others, and picking up where AI left off with people who aren’t actually interesting in learning rubs most here the wrong way.
It’s nothing super specific to AI as much as it is trying to respect people’s time and effort. Presenting a problem is different from presenting incorrect AI replies asking what’s wrong with it.

[formal tide]

yep u shouldnt rely on ai. always use unity documentation as a source and then u can use other sources as well 😄

[north kiln]

To me it's just an insulting thing to suggest as a starting place in a place full of developers who spend their own time here helping others.

[eternal needle]

Not because of how controversial it is. Because they are repeating the exact same points multiple times without actually reading what anyone is saying.

[fickle plume]

Not to mention, stuff you get from LLM is the average terrible code it scraped that you are learning from.

[formal tide]

i understand ur hard work and i appreciated. i didnt know recommending ai was disrepectful

[sharp solar]

what type of question can you even ask here that isnt easily googled anyway

in the beginner channel

[eager spindle]

for me I really just help people even if they can Google it

Then tell them to Google it next time

spoonfeeding sure but they need a head start

[visual linden]

Learning to learn also falls under beginner topics I feel. I'm happy to point people to resources or let them know what they can try googling to find what they're looking for.

[north kiln]

Often the problem is they haven't developed the knowhow to know what to look for and need a push in the right direction

[shut swallow]

does saving a dict to JSON not need any extra steps now?

[eager spindle]

I don't like when the top answer of a forum is just telling others to Google it or linking to another page without elaboration, top searches get rearranged over the years and forums can get deleted.

Speaking from personal experience when messing with Playfab, it got bought over by Microsoft and they deleted the old forums entirely

[eager spindle]

It's always been serialisable from what I remember?

[eternal needle]

No, I believe I @ u in a message above a few hours ago showing that newtonsoft can do this

[shut swallow]

ah ok, sorry it's been a long day my memory is flatlining

[eternal needle]

Np, was saying it more as a reminder

[sharp solar]

because you have to recreate an array every time its resized, is an array still the correct thing to use for a list that resizes all the time?

or is there a better way

[eager spindle]

Why not use a list?

[eternal needle]

There is a List in c# which handles this for you

[sharp solar]

a list is just a resizeable array right

[eternal needle]

It just handles the logic for you, you can treat it as a resizable array

[eager spindle]

Not as related but if you really want to optimise your list so much you can also look into object pooling

Otherwise, sticking to a list/making your own logic for a resizeable array is just fine

[eternal needle]

I dont think this is related at all. We dont know what this is a list of, object pooling doesnt apply to everything

[burnt vapor]

Also, if you want to avoid constantly reallocating an array to fit the new size, a List just hides this and doesn't make it any better.

Allocate an array that is big enough for your use case, or consider handling it in batches based on what fits and handle the rest the next round.

This is also why Unity provides the ability to pass arrays into various methods because you allocating it once is a lot better than Unity constantly making one when you call the method

[cosmic dagger]

is it possible to make Unity not use GPU at all for rendering and only use CPU?
for context, before i had issues with my nvidia drivers not being detected and Unity was running CPU-only, which was.... bearable but still too slow. i updated and fixed the drivers and they are running well now. now i am trying out an asset (Crest) and i encounter visual glitches, and they might be caused by the drivers being funny. i want to see whether it's the asset or the drivers that are at fault.
so my question is whether I can go back to that CPU-only state without completely turning off the drivers for my entire PC?

i looked it up online and it seems like it's super nonstandard and most forums suggest -nographics which turns off the display of the entire editor but that is not my goal

[visual linden]

If you have an Nvidia card, you can open Nvidia Control Panel and assign which GPU to use for which program. I don't know what the AMD & Intel equivalent would be but I'm sure they exist.
This as far as I know is not something you can specify from within Unity.

[cosmic dagger]

aha i see, that would make sense, let me try

[sharp bloom]

I don't understand how unsubscribing from events work.
If have I have an arrow function like OnSomethingHappened += () => {DoSomething();};, do I need to unsubscribe? And how would I do that?

I just found out my scene breaks when I reload...I think it's because I haven't unsubbed to any events

btw, while the inline segmant isn't there. the paste sites can be found in #854851968446365696

What you're doing there is creating an anonymous delegate that then calls your DoSomething function.
What you want to do is something like OnSomethingHappened += DoSomething();, that way you can unsubscribe later on with OnSomethingHappened -= DoSomething();.
Here's a good resource on the topic
https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/delegates/delegates-with-named-vs-anonymous-methods

[rugged beacon]

yea i was looking for the inline specificly

[sharp bloom]

So if I I understand correctly, if the event is System.Action type, was the anonymous delegate needed at all?

If that in itself is a type of delegate?

[shut swallow]

    {
        data.timeElapsed = Mathf.Min(data.timeElapsed, this.elapsedTime);
        data.gameTimeElapsed = Mathf.Min(data.gameTimeElapsed, this.gameTime);
        if (levelCompleted && data.timeElapsed > this.elapsedTime || data.timeElapsed == 0)
            data.levelTimeTracker.Add(id, elapsedTime);
    }```how could I rewrite this so I can actually store the least amount of time it takes for a player to complete a level? Right now all I get in my json file is zero

[frigid sequoia]

Hey, how could I like... make some kind of event system where I calculate a value and then send a call to see if there is anything extra that would like to modify that value?

Like, imagine a method that makes an attack, so it calculates the damage of it, but the character has an item that goes like "your attacks do magic damage instead"

Like, I cannot really handle that with events can I?

[shut swallow]

seems like the dict was not even established in the first place

https://paste.mod.gg/wgyyysyfmtco/3

[sharp bloom]

Okay, so I have changed this

ClockScript.OnSecondsChanged += (int context) => 
{
    tickTimer += 1;
    if (tickTimer >= 20)
    {
        tickTimer = 0;
        EndTurn();
    }
};

into this

ClockScript.OnSecondsChanged += TurnEnderEventHandler;

private void TurnEnderEventHandler(int seconds)
{
    tickTimer += 1;
    if (tickTimer >= 20)
    {
        tickTimer = 0;
        EndTurn();
    }
}

private void OnDisable()
{
    ClockScript.OnSecondsChanged -= TurnEnderEventHandler;
}

I think now it's getting unsubscribed correctly

[visual linden]

Yeah looks correct :)

[restive kettle]

guys if i wanna change the cupe color in c# i saw someone using cube.getcomponet<Render>

but the vsc aint suggesting it to me

[hexed terrace]

"it" - what isn't it suggesting?

[visual linden]

Try <Renderer> :) https://docs.unity3d.com/6000.1/Documentation/ScriptReference/Renderer.html

[hexed terrace]

cube is a mesh, your IDE doesn't know what that is. It also can't have a component, they go on GameObjects.

You need to create a GameObject variable, assign the thep to it and then GetComponent will work

Unless of course, you created the var as cube then it's just what halfspacer said

[restive kettle]

omg thanks <3

[shut swallow]

Hey, it's been here for a while, can anyone have a look?

[frigid sequoia]

Pretty sure that if you are getting how long is taking the player to complete a level it should never be 0. Why are you even checking for 0? The default value should probably be like Mathf.Infinite

[sharp bloom]

Where should I call this?

[naive pawn]

i think you'd want parens around the ||

[sharp bloom]

Oh nevermind, void OnDisable() of course

[naive pawn]

perhaps not a fix for the issue, just a sidenote

[shut swallow]

the idea is when the program is ran for the first time the value is set to 0

should I just make inital value very large to fix this?

[frigid sequoia]

The initial value should be infinite, since you are looking for a smaller value to replace it

[naive pawn]

using 0 is a fine default value imo - a flag for "no value"

[shut swallow]

    {
        if (levelCompleted && data.timeElapsed > this.elapsedTime)
            data.timeElapsed = this.elapsedTime;
            data.gameTimeElapsed = this.gameTime;
            data.levelTimeTracker.Add(id, elapsedTime);
    }```Yea this seems to make a lot more sense

[naive pawn]

you're missing braces there

[frigid sequoia]

It's fine as a default value, you can work around it, but I prefer infinite here, easier to setup

[shut swallow]

quick question, when I store the key-value pair into the dict, how would I replace the {id, elapsedTime} with the shorter version?

[hexed terrace]

dictionary[key] = newValue;

[naive pawn]

[id] = elapsedTime?

[shut swallow]

do I just replace the last line with this? What happens when there's no inital key-value pairs

[hexed terrace]

You'll need to check for the key first

[naive pawn]

the entry is created

[naive pawn]

you don't need to check for setting

[shut swallow]

ok so just let data.levelTimeTrack[id] = elapsedTime take care of it

[eager scarab]

i tried this and only going right and jumping seems to work, going left (A key) doesnt do anything for some reason (i went to sleep thats why i responded late)

have you tried doing some debugging to check if it's being picked up?

[eager scarab]

i would but i dont understand the 1f; thing in the if statements, i probably should look it up

[naive pawn]

could just Debug.Log($"A: {Input.GetKey(KeyCode.A)}, D: {Input.GetKey(KeyCode.D)}");

[eager scarab]

both inputs are being read

[naive pawn]

when you only press A?

oh wait you're clamping the speed so it's only ever positive lmao

[eager scarab]

that would make sense why its not working then lol

what would be a better way to go about with the calculations

i made someone elses code my property to make it and planned to get it working then lookup any details i dont know to slowly increase my knowledge based off things that worked but it seems that i probably should do a little bit of looking up before hand

[lusty star]

anybody got the tech support number for this?

it keeps not adding whitespaces, yes i checked the settings

[ivory bobcat]

Min speed should be -10

[eager scarab]

oh ok

thx

[naive pawn]

clamp at -maxSpeed, maxSpeed

[eager scarab]

yea that works but ill do the way chris said since only one variable needed

[shut swallow]

do I directly get values from a dict by levelTimeTracker.TryGetValue(Id, out var value) given some {Id : value} pair?
do I need to define the type of value being outputted or does it just output whatever the associated value is?

[naive pawn]

var means the type is inferred. if it weren't inferrable, you wouldn't be allowed to use it there

[shut swallow]

levelTimeTracker.TryGetValue(Id, out float value) something like that

[naive pawn]

you can hover over the variable to see what its type is

[naive pawn]

check in scene view to see if anything is overlapping it and check if the text in the component is correct

[warped pendant]

it looks fine in scene view. does that potentially narrow it down to the camera?

[naive pawn]

maybe, i think #📲┃ui-ux would be more suited to help with this

[warped pendant]

ok. ty for the response

public class FinishFlag : MonoBehaviour

        {
            GameManager.Instance.UpdateLevelCompleted(true);
        }
    }
}``` I attached this script to 3D worldspace UI element but somehow no collision came up

both the player and the flag has a collider, with the flag being trigger

[naive pawn]

not sure physics and recttransforms will play nice with each other

[shut swallow]

did the other way around and still didn't work

[naive pawn]

what other way around?

[shut swallow]

on trigger enter on the player getting the tag of the falg

[frosty hound]

If this is just for the flag, you should be using a sprite renderer, not UI.

(Not that it changes the physics)

[naive pawn]

that doesn't make a difference

it's the physics check that I don't think would work properly

[shut swallow]

why tho?

[naive pawn]

anyways, the player has a rigidbody, right?

[naive pawn]

recttransforms work a bit differently from normal transforms

[shut swallow]

no, it uses a capsult collider because it moves with a kinematic character controller

[naive pawn]

well, that'd be why

physics are driven by rigidbodies

[shut swallow]

ahh

[naive pawn]

...wait kcc doesn't use rbs?

i thought it did, but i didn't really look into the actual package

[shut swallow]

I think it's a toggle

I just looked at the panel now that you mentioned it

and there's a rb interaction type

[naive pawn]

why is your flag a ui element anyways

[shut swallow]

idk, it's just a visual element in worldspace so I figured just to use ui

[shut swallow]

nvm it still didn't work

ok adding a rb worked

ok one more question

how do I make sure Timer gets to save the data before TimeDisplay pulls from the JSON file?

also, why is the dict not saved within the JSON?

I checked my files and the dict is just not there

[teal viper]

How are you serializing it? Unity json serializer doesn't serialize dictionaries.

[valid violet]

There is trick how to serialize dictionaries with lists

[naive pawn]

you can just use a spriterenderer for that

[shut swallow]

I thought they did since json has dict support no?

[naive pawn]

you're introducing some really unneeded complexity

[teal viper]

Lists are not dicts.

[shut swallow]

typo mb

[shut swallow]

Ight I'll just change it to a sprite

[teal viper]

You've yer to show what your Player data serialized part looks like.

[shut swallow]

oh uhh is it this

[teal viper]

Yeah, you can't serialize the dict just like that.

            Vector2 direction = new Vector2(x, cubeRigidBody.velocity.y).normalized;

            //cubeRigidBody.AddForce(Vector2.left * velocity, ForceMode2D.Impulse);
        }
    }
}

I am confused at the last part, when I do cubeRigidBody.velocity = direction * -speed; the player moves faster compared to x * speed

Can anyone explain please?

This is a player movement script

I understand 90% of my code only, the rest doesn't make much sense to me either due to shit tutorials

[valid violet]

there is trick but not shure it will work fine for your case https://docs.unity3d.com/ScriptReference/ISerializationCallbackReceiver.html

[open apex]

I'm not totally sure what serialization is to begin with :d

[naive pawn]

that one isn't for you

[steel smelt]

They weren't talking to you

In the right side check, you multiply by speed prior to normalization. In the left side check, you normalize and then multiply by speed

[naive pawn]

what scenarios are you comparing, exactly?

[valid violet]

@open apex you normalizing vector after speed was aplied your actual speed is changing vector direction instead of affecting actual speed

[shut swallow]

thanks lemme read into it

[open apex]

I don't undestand what you mean.But here is an explanation, basically I am trying to add player movement to my character, I have decided to use velocity and to adjust how fast the player moves I have given it a variable called speed. What I did was "cubeRigidBody.velocity = new Vector2(x * speed, cubeRigidBody.velocity.y).normalized;" no matter how high "speed" was the cube wouldn't move faster, so I looked up at a tutorial, they did " Vector2 direction = new Vector2(x, cubeRigidBody.velocity.y).normalized;
cubeRigidBody.velocity = direction * speed;"

instead it start to move just fine but I don't understand how, is as foo mentioned because it was normalized? If I remember correctly when normalized the max value of the variable would 1 or -1 (?)

[naive pawn]

normalization of a vector makes its magnitude 1

for a vector2, that means sqrt(x*x + y*y) = 1

[open apex]

Owhhh

[valid violet]

You need rb.velocity = direction.normalize*speed where direction is Vector2

[naive pawn]

if this is supposed to be a sidescroller context with gravity, then you don't need to normalize the vector at all, since that'd be affecting gravity

[open apex]

I am not exactly sure why I would need to normalize it either as it's just 1 and -1, I just do it because it's "good practice"

[naive pawn]

you don't need to normalize in this scenario

in this context, normalization would be done to turn some x/y values into a direction, with magnitude 1
in a top-down game, if you press W and D and turn that into a vector, that would be (1, 1), which is actually going faster than going only right or going only up, so normalization would make the magnitude, and thus overall speed, uniform

but your code seems to indicate you're in a sidescroller, so you don't need anything like that

[open apex]

it's not w and d it's buttons

UI

[naive pawn]

i'm giving an example

[grand snow]

wow 😐

[open apex]

Ohh ok

[valid violet]

@open apex Normilzed make vector Magnitude equal to 1 not X and not Y the lenght of vector so if u want ur player move with speed 5 you normalize the vector coz in else case vector magnitude can have length 10 or .3 and speed will not be 5

[naive pawn]

damn use some punctuation 💀

[open apex]

Hunter is a proper pc user

but I understand what he means

[grand snow]

Its useful for many things e.g. get direction from a to b, normalise and then scale to new desired length with ease

[eager scarab]

how would I go about detecting if the character is on the ground (2d, im using capsule collider 2d and rigidbody 2d on the player)

[open apex]

I love programming, I've got very little to no idea what I'm doing and I'm going of based off of theory and a bit knowledge, if something doesn't work = research, if it does = understand how it works and keep on moving

[eager scarab]

(cause rn there are infinite jumps, even in the air)

[naive pawn]

there's quite a few ways, try googling it

[jolly stag]

I was wondering if anyone was free to help me with something? I'm having issues getting collision to work, it's supposed to hit something with the tag "Power Up" and then destroy itself but it's not recognising it and won't hit it. I have a collider and Rigidbodys on both objects.

[valid violet]

Did you set the tag of target?

[jolly stag]

Yes

[naive pawn]

have you tried debugging to see if the message is being called

[valid violet]

Set the Debug.Log(collision.gameObject.name) and check if it works

[naive pawn]

also, is the powerup a trigger?

[jolly stag]

I have but not in the way set out above, I'll give that ago and report back.

[jolly stag]

Yes

[naive pawn]

then there wouldn't be a collision

use the trigger message

make sure to update the parameter type as well, they have different signatures

[jolly stag]

using System.Collections.Generic;
using UnityEngine;

public class Bullet : MonoBehaviour
{
    public int bulletSpeed = 5;
    private float bulletRange = 10.0f;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        transform.Translate(new Vector3(0, 1, 0) *bulletSpeed * Time.deltaTime);
        if (transform.position.z > bulletRange)
        {
            GameObject.Destroy(gameObject);
        }
    }
    private void OnTriggerEnter(Collider other)
    {
        if (CompareTag("Power Up"))
        {
            Destroy(gameObject);
            Debug.Log("Hit");
        }
    }
}```

I am using OnTriggerEnter

[naive pawn]

CompareTag there would be checking the tag of the current GO

"bullet" doesn't seem like it'd be the same object as the powerup, so you probably want to check the tag of other

[jolly stag]

What I tend to do is check if the player is colliding with the ground or not that then makes a isGrounded variable to true, then ensure that in the if statement that you test for a key press add the isGrounded variable as well.

[eager scarab]

i tried to do that but it said something like the isGrounded thing wasnt valid

[valid violet]

use this instead CompareTag is doing nothing ````if(other.tag=="Power Up")```

[eager scarab]

also are tags for colliders gonna be useful to differentiate like a wall from the ground, so i cant just wall bounce alot

[naive pawn]

you can use the CompareTag just fine, doesn't need to be a tag comparison - just needs to be on other

[jolly stag]

Works like a charm, so other just takes what it's hitting and checks it's tag?

[naive pawn]

yeah, you were checking the current GO before as i mentioned

[jolly stag]

That makes sense, Thank you!

[valid violet]

You need to do other.gameObject.CompareTag("Power Up")

[naive pawn]

what was the error you got

[eager scarab]

unsure cause it was a while ago that i tried

[naive pawn]

no you don't, CompareTag is a method on Component as well

you don't need the intermediate .gameObject

[naive pawn]

ah thought you were just trying it

[valid violet]

What do you mean it cannot work such way it is not possible CompareTag("Power Up") this code is 100% uncorrect

[naive pawn]

didn't say it was

[jolly stag]

Alternatively you can shoot a raycast at your feet and if it hits something then you're grounded

[naive pawn]

other.CompareTag("Power Up") and other.tag == "Power Up" are both fine
.gameObject is unnecessary

[valid violet]

I didn't remember if collider have field tag so used gameObject to be sure it will works

you are right there

[grand snow]

CompareTag() is better to avoid a string allocation

[naive pawn]

only with a taghandle, no?

[grand snow]

Hm? CompareTag() doesnt need to allocate the tag string in managed memory for the comparison.
Should be why CompareTag() even exists

anyway bit much to think about for beginners

[naive pawn]

could you elaborate? is this something about the comparetag using extern'd methods?

(im curious about the internals of what was done there)

[grand snow]

Yea, this just passes the managed object to a native function to perform the comparison so we avoid allocation.
the tag property however needs to produce a string in managed code for comparison to then be done with string == string

[naive pawn]

ah, cool

(checking my understanding) so it's not the == vsCompareTag that's optimized, it's the removal of .tag that's better?

[grand snow]

Yea, string comparison is done either way but one is a tad better.

And ofc TagHandle exists to further improve things

[eager scarab]

I looked up how and got it working with this, is there any optimisations i should make or should this be fine?

im thinking i could do the 2 ifs in a if and elseif based on diff languages ive used but idk if thatll be true for this

[naive pawn]

fyi, see below !code

I am afraid I am also a newbie so don't know much about optimization but that is what I did when I had the issue :)

[naive pawn]

you don't need the ifs (in case you missed my message)

[eager scarab]

yeah im newbie-er, started yesterday and barely did anything since lol

[naive pawn]

_Grounded = hit.collider != null; would also work

also fyi for the future, else exists

[naive pawn]

what do you mean by "check" exactly?

[eager scarab]

idk why i didnt try this before since thats exactly what it is in other languages lol

[naive pawn]

yeah pretty much every language uses if and else

[eager scarab]

thanks, didnt know hit was already a boolean

[naive pawn]

the differences are in else if vs elif vs elsif, and then/fi/end

[naive pawn]

it isn't, it has an implicit boolean conversion - it can be treated as if it were a boolean

// Implicitly convert a hit to a boolean based upon whether a collider reference exists or not.
public static implicit operator bool(RaycastHit2D hit)
{
    return hit.collider != null;
}

comparing between data.timeElapsed and this.elapsedTime

But I have a bigger problem here apperently

there's no saving values

I've serialized the dict properly now but it seems like I can't save my data

[regal magnet]

what is the best way to add dialog system to my 2d unity game? i saw tons of video with different ways which one is your fav?

[rich adder]

INK

[naive pawn]

well yeah you never actually told it to save it anywhere

[hexed terrace]

buy an asset 😄

[naive pawn]

there's no "best", in general

[rich adder]

Ink is a good system and is free

Comes with its own markup you can easily interact mid dialaugue and branches

[regal magnet]

i dont try yet but ink was the system i like

[shut swallow]

wdym? Isn't if (data.levelTimeTracker.ContainsKey(SceneManager.GetActiveScene().name)) { data.levelTimeTracker.Remove(SceneManager.GetActiveScene().name); } data.levelTimeTracker.Add(SceneManager.GetActiveScene().name, elapsedTime); saving the data?

[rich adder]

I used it a couple of times its real good for a free system tbh , depends how complex you need

[naive pawn]

it's saving to PlayerData, but it's not actually statically saving anywhere else? (to network/to disk)

what is your save system?

you're leaving a lot to be assumed

[regal magnet]

i am looking for basic one because i kinda overwhelm with other tutorials so far basic dialogs and little bit choice answer is enough

[shut swallow]

https://www.youtube.com/watch?v=aUi9aijvpgs I'm following this tutorial but to paraphrase it it's saving to a data persistence manager, where the singleton saves a snapshot of the data to store it in json

[rich adder]

define " basic " building your own will be a lot more work than quickly adopting already fleshed out system , granted there is an initial learning curve but it's real easy imo. Ofc you can do your own with scriptable objects and arrays etc. I think unity has a demo for that with thr Chop chop demo

[regal magnet]

good idea i was totally forget to look unity's own tutorials

[shut swallow]

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

[rich adder]

sure take a look at them. The most basic string[] dialogues lol

[hexed terrace]

Nothing there saves to a json. (I missed the tabs) It just adds data to a dictionary(?)

        }
    }

}```

[shut swallow]

it has the initial values of the playerdata but not any updates

[foggy crypt]

Guys, any advice on how to make Transform.Translate get the Vector3 once, and move in that direction, even if the direction changes?

[hexed terrace]

I can't see where DataPersistenceManager.Instance.SaveLevel() is called

[naive pawn]

idk anything about using json in c#

[naive pawn]

get the Vector3 once
what do you mean by this?

[rich adder]

wdym get the Vector3 once? which vector3 are you talking about ?

Vector3 never changes, eg Vector3.right will always go in the same direction no matter rotation etc.

[naive pawn]

if you want to apply a translation that doesn't care about the rotation, you can set Space.World or add to the position directly

[foggy crypt]

I figured it out 🙂

[eternal needle]

didnt really see any of the context but it can using newtonsoft
https://www.newtonsoft.com/json/help/html/serializedictionary.htm

[rich adder]

newtonsoft > JsonUtility

[sour fulcrum]

not that it's a direct solution but might even just be worth turning that dict into a serializable struct or something in the event you want more data in there too

in some situations maybe "overkill" but if your making a whole save thing anyway

[rich adder]

one thing newtonsoft has weird issue with Vector3. not sure if thats still a thing but you have to disable "self-referencing loops " or whatever the option was

[naive pawn]

what, for like normalized or something?

[eternal needle]

There is another package with custom converters for unity, handling most of the unity types at least

[rich adder]

yea

but you just add cs JsonSerializerSettings settings = new JsonSerializerSettings { ReferenceLoopHandling = ReferenceLoopHandling.Ignore }; I think and it goes away

[shut swallow]

    {
        if (GameManager.Instance.levelCompleted)
        {
            SaveLevel();
        }
    }``` (within the singleton)

[naive pawn]

why would it serialize properties rather than their backing fields

[shut swallow]

how long does it take me to rewrite this in newtonsoft?

[rich adder]

No Idea tbh I just learned the hard way I had to do that.. also you cannot disable it on Unity Cloud so you are stuck making custom Position/Vector3 of your own basically almost a ORM

[shut swallow]

unity cloud strikes again

[rich adder]

its the same thing. except the method changes from
JstonUtility.toJson vs JsonConvert.SerializeObject

[eternal needle]

https://github.com/applejag/Newtonsoft.Json-for-Unity.Converters

[rich adder]

ima check this out thanks! this only works for local anyway right ?
I'm stuck making custom structs for UnityCloud Save because thats server side and I cannot change anything newtonsoft

[eternal needle]

I'm not sure about this whole cloud aspect of it or what you can or can't do there tbh

Could be valuable even just seeing how they handle it in the package I linked, if that helps for your case

[shut swallow]

anyways I don't think I have time to experiment, could someone tell me why does this not update my data?

[rich adder]

basically you save

        var playerData = new Dictionary<string, object>{
          {"firstKeyName", "a text value"},
          {"secondKeyName", 123}
        };
await CloudSaveService.Instance.Data.Player.SaveAsync(playerData);```

But if you pass a serialized object in `object` like a struct that contains Vector3. you get the same error i mentioned earlier about newtonsoft self-referencing loop thing but you cannot change anything since its on unitys server side of things
I just ended up making my custom `Position`(3floats) like vector3 anyway but still
I have a Vector3 to Position converter and vice versa

[rich adder]

which part SaveLevel ?

[sour fulcrum]

why on earth did i think the basic value types weren't object's. thank you for accidentally enlightening me

[shut swallow]

https://paste.mod.gg/nsbzmxzaasck/1

[rich adder]

revelations!
but yeah sometimes I still don't know if I should just use object or I'm better off using a T generic, always use generics cause iirc with object there is some boxing that needs to happen? I'm no expert in this though so not sure

[sour fulcrum]

Yeah I always get worried about direct generics not doing serialization related stuff well since unity object classes dont like it

without defining them in a inheriting type

i have a generic INetworkSerializable struct i still gotta test

[rich adder]

Oh that I did not know lol TIL

[naive pawn]

well they aren't in java/js for example so it's not an unreasonable assumption

[rich adder]

so its not saving ? sorry I just got here

[valid violet]

object class is created by Microsoft for Companies to ask about it on the Interview )

[shut swallow]

yea, the JSON file only have the presets

[rich adder]

what else it supposed to have?

[shut swallow]

well, changes to values in playerdata

[rich adder]

you logged the values before it being serialized in a file ?

[shut swallow]

how so?

and also, how can I fix this?

[rich adder]

Debug.Log

You are able to fix it if you narrow down to the cause

[shut swallow]

ok I do have a key-value pair

I just could not call it

[rich adder]

not sure what you mean by that

[shut swallow]

on my display script

[shut swallow]

basically I did save data in the json

but I couldn't call it

[rich adder]

I still don't know what you by "couldn't call it "

calling what

[shut swallow]

recalling the serialized values of PlayerData that is stored into the JSON to a script

[sour fulcrum]

loading?

[shut swallow]

yea

loading

[sour fulcrum]

this could be worth doing?

[rich adder]

De serializing

If it's saving the data then loading isn't any different

[rich adder]

So the save values are correctly saved in the json file ?

[shut swallow]

yes

my singleton could see the new value

[sour fulcrum]

save values

did the values from the dict save

[shut swallow]

yea

all values looks right

[rich adder]

so which part isn't working lol

[shut swallow]

the part where I wanted to get the value and display it

[rich adder]

When you log best time what value do you get?

[sour fulcrum]

does updatetext run after loaddata

[shut swallow]

I got 14 seconds in the JSON file

so it should show

[shut swallow]

im not sure about this

[sour fulcrum]

it needs to 😛

[shut swallow]

i know that its more like idk how execution order works in this case since LoadData is called by the singleton

[sour fulcrum]

well

run it in loaddata after you set besttime

see if it works

[shut swallow]

nope

[willow iron]

Vector3 dir = (path.vectorPath[currentWaypoint] - transform.position).normalized;
so got this vector3 from the A* pathfinding algorithm. I already have a way to smoothly rotate my 2d gameobject towards the vector using slerp, but i also have a mesh that i wish to rotate towards this direction. plugging in my transform directly doesn't work as it simply flips left and right instead of actually rotating.

simpily put, i want to rotate towards this vector3, but gradually instead of all at once. any tips?

[shell sorrel]

depends on how you want to do it

does it move to one point to the other with a fixed speed or a fixed duration

normally most would just use something like Vector3.MoveTowards to push the transform in a direction per frame with a max amount it can move per frame

[willow iron]

fixed speed

[shell sorrel]

then you can add other concepts as needed like how long it takes to accelerate and deaccelerate

[scarlet skiff]

i want my player to be able to spawn in a random position (2d platformer side scroller).
whats the most optimal way to get a random position within a certain distance of the players death location that the player can safely spawn in (meaning head or toes wont be inside any objects with the layer ground).
if there is a tutorial that touches on this mechanic specifically, please let me know

[willow iron]

i already have the movement and stuff set, i just need to rotate a seperate mesh towards the vector3

so the variable needs to remain a vector3, no quaternion conversion

[shell sorrel]

you can just convert the vector3 to quaternion with LookRotation as needed though

get the Quaternion.LookRotation of your directinal vector, then you can use Quaternion.RotateTowards feeding in the objects current rotation, and the LookRotation and a max degrees update

i just wanna check is this the right channel to ask for help?

[frail hawk]

read the channel title

ah sorry i dont really go in servers thank you tho

ive been struggling with finding the right resources and i dont know where i should really look for learning unity, could someone point me in the right direction?

Hello guys, first time here!
Trying to instantiate a GameObject @ a certain time rate, but it keeps instantiating at every frame even after the timer resets
void Update()
{
Timer = Time.time;
if (Timer >= SpawnRate)
{
SpawnBalloon();
}

    MoveSpawn();
}

void SpawnBalloon()
{
    Timer = SpawnRate - SpawnRate;
    Instantiate(Balloon, new Vector3(transform.position.x, transform.position.y, transform.position.z), Quaternion.identity);
}

[valid violet]

add the line Timer = 0; after SpawnBalloon

and Timer+=Time.deltaTime

[slender nymph]

They're doing that inside SpawnBalloon, the issue is how they are tracking time though as just setting it to 0 won't work

[valid violet]

not Timer = Time.Time it is not correct

    {
        Timer += Time.deltaTime;
        if (Timer >= SpawnRate)
        {
            SpawnBalloon();
        }

        MoveSpawn();
    }

    void SpawnBalloon()
    {
        Timer = 0;
        Instantiate(Balloon, new Vector3(transform.position.x, transform.position.y, transform.position.z), Quaternion.identity);
    }```

[eager scarab]

im confused, how is void wrong in void FixedUpdate()

using UnityEngine.InputSystem;

public class PlayerController : MonoBehaviour
{
    public Rigidbody rb;
    public float moveSpeed;
    private Vector2 _moveDirection;
    public InputActionReference

    void FixedUpdate()
    {
        rb.linearVelocity = new Vector2(_moveDirection.x * moveSpeed, _moveDirection.y * moveSpeed);
    }
}```

[modest dust]

You're missing a ; and a field name after InputActionReference

[eager scarab]

oh

doesnt say that

but its fixed now

[daring tree]

Thanks @valid violet , that solved it!

[modest dust]

It does

[eager scarab]

oh

yea it does just more complicated way of saying it

[humble ridge]

Hi guys! I was watching a tutorial of Unity Input System in Unity 6, and when they use MovePosition in rigidbody, they multiply it with Time.deltaTime, but the logic is implemented in FixedUpdate. Why not use Update instead? I guess cause it's physics related, but why use deltaTime then?

[modest dust]

Member declaration, the member being public InputActionReference, followed by invalid void which shouldn't be there, that's why void is underlined

[slender nymph]

because you didn't finish the previously line it thinks you are trying to finish it there but void is a reserved keyword so it is not valid in that previous line

[humble ridge]

Also, the vector2 values of move action are in update, so could this cause inconsistencies if there's frame drops?

[frail hawk]

i think it doesnt make any difference to use deltatime inside FixedUpdate

deltatime and fixeddeltaTime is what i am saying

[humble ridge]

I've read that it can be cause the fixed updated rate could be modified over time, but a part from that, idk why they use it then

[frail hawk]

MovePosition as the name says is using the rb position, that is why you need to use it

[humble ridge]

Hmm okay, so I can use FixedUpdate for MovePosition without worrying about using deltatime or fixeddeltaTime ?

[frail hawk]

you have to use deltaTime, in short

[humble ridge]

And for reading the values of vector2 in Move action, it's okay to keep it in update or better to set it in fixed update too?

[frail hawk]

it is unclear what you are asking. do you have the code

[humble ridge]

Ooooh okay, so what you're saying is I can use both the times (fixed and normal delta times)

Sure, I can send you the unity tutorial link too if you want

[humble ridge]

This method is called inside FixedUpdate

[frail hawk]

yeah looks ok from here

[humble ridge]

Sure, but sorry if I didn't make myself clear. Why do I need to use a Time variable (deltatime and fixeddeltaTime)?

I thought that fixedupdate was enough to not depend on framerates

[night raptor]

fixedUpdate is run independently from the framerate yes, but if you later change the physics framerate from the default of 50, maybe even runtime by script, it won't be independent

[frail hawk]

good questions actually, FixedUpdate runs 50 calls per second as we know, so why the deltatime

[night raptor]

You also generally want to work with some clearly defined units, like acceleration of m/s^2, you may not get any of that if the physics timestep (Time.fixedDeltatime) is not factored in correctly

[humble ridge]

Okay, and if I change the framerate from 50 to 25, Time.fixedDeltatime also changes?

[night raptor]

Yes, it gives the time between physics frames. In case of 50 it would be 0.02, for 25 it would be 0.04

[humble ridge]

Thanks! Now I got it

[night raptor]

Btw, in fixedUpdate, it doesn't really matter whether you use Time.deltaTime or Time.fixedDeltaTime, because deltaTime is identical to fixedDeltaTime during fixedUpdate. It is good practise to prefer fixedDeltaTime though to indicate that you are working with physics timesteps

[humble ridge]

Also, this m_moveAmt will be dependant on normal frame rate if called in update right? Or it has nothing to do with it

[night raptor]

Shouldn't have anything to do with it. AddForceAtPosition increments Rigidbody.GetAccumulatedForce (well not the getter of course) which then will get applied during the next physics update. AddForceAtPosition doesn't take Time.deltaTime into account in any way as far as I know, it just applies the given impulse (in the impulse ForceMode) to the counter (accumulatedForce). Don't know how much sense that makes to you. What is important though is that you do ForceMode.Impulse as you do, if you used something like ForceMode.Force, you would get different jump heights if you changed the physics time step (your regular framerate wouldn't matter still). ForceMode.Force expects you to apply that force continuously in every frame, Impulse you can apply only once.

[humble ridge]

Got it, thanks!

Really, that was a really good explanation, tysm!

[night raptor]

guys can someone help me with some tutorials/pathways from learn.unity.com? some are good? i have a best/good knowledge in coding but not in unity, in c/c++ but i need to learn unity for a project. i did Unity Essentials and Junior Programmer and i want to start rn VR Development from learn.unity.com/pathways but i don t feel like i improved a lot, if someone know some tutorials/courses from learn.unity.com? in this ideea. i need to learn unity/VR

[humble ridge]

Nothing, I google it and I found it, sorry & thanks!

guys take a look at this code snippet
https://paste.mod.gg/ntklmoluocoa/0

I have an object with x rotation -10 degrees and I want it to go to 40 degrees it does exactly that BUT for some reason the rotation the gets reversed and it comes back up. I dont want that to happen anyone know any solutions?

[wintry quarry]

this code wouldn't do that last part

you'd have to show more code

[vocal quiver]

Here it is https://paste.mod.gg/xwjigquavjbw/0

[wintry quarry]

you should share the full script

[foggy crypt]

Need help rotating an object while it is moving via Transform.Translate
Tried LookAt and RotateTowards and a couple of other methods but in the end the result was - that the model of the object was not rotating.
The only thing rotating were Vectors and directions of X and Z Coordinates

(What I'm trying to do is - create a projectile of a straight line and make it look directly at the player while flying)

[wintry quarry]

Transform.Translate will not affect the object's rotation (though it may be affected by it) so your question doesn't make sense

[vocal quiver]

the full script is like 300 lines is it ok if I share just that function??
