[latent mortar]

what game should i make then

[real grail]

Start simple 2d platformer then go bigger on your next project

[latent mortar]

idk how to make a 2d game

[real grail]

Look on google youtube and such pleanty of tutorials for you to start.

[charred spoke]

Pong

[latent mortar]

No clue at all how to do that

[charred spoke]

Perhaps game development is not for you then ?

[polar marsh]

https://learn.unity.com/course/2d-beginner-adventure-game?utm_source=learn_recommendation

[latent mortar]

Nah just Tryna learn

[polar marsh]

I am also a beginner right now i am watching Unity Learn Junior Programmer pathway

[charred spoke]

If you have finished the junior pathway you should have an idea of how to make pong. If not, sit down and break down the game into small problems then start tackling them one at a time

[polar marsh]

I am still watching so idk pong right now

[charred spoke]

I was referring to the other guy who claims to have completed it

[polar marsh]

ohk

[lofty mirage]

Why are you learning game dev then?

I don't understand

don't you want to learn to make games?

[fickle stump]

@lofty mirage have you figured coroutines out?

[lofty mirage]

I mean I'm used to just declaring them as
private Coroutine coroutine;
starting them with
StartCoroutine(coroutineFunc());
and having coroutineFunc() defined as
private IEnumerator coroutineFunc() {}

It was more to understand if there were some other ways of doing it I guess

but my "baseline" works

[lofty mirage]

Did you want to ask a question or were you just checking up on me?

If the latter, that's very nice! 🙂

[fickle stump]

Now i feel bad for wanting to ask smth <-

[lofty mirage]

Oh no

go ahead haha

it was 50/50 so

Tell me

I'm very happy to help if I can

[fickle stump]

I lost the beeing nice gamble

I think i figured it out.. gotta wait

[lofty mirage]

haahhahaa

Well basically if you use yield return you have to put the statements in a IEnumerator function

you can't start an IEnumerator function without StartCoroutine(IEnumFunc()); in my knowledge

the main important things I think

[lofty mirage]

Was that your bug?

[fickle stump]

(public void StartCoroutine(int waitTime) { if (isCoroutine == true) { coroutine = WaitAndDisable(2); StartCoroutine(coroutine); } })

Wrote it like this and i think this fixxed this?

[lofty mirage]

Can you share WaitAndDisable too?

what did you change?

[lofty mirage]

(technically just the function signature)

[fickle stump]

( private IEnumerator WaitAndDisable(int waitTime) { yield return new WaitForSeconds(waitTime); })

[lofty mirage]

So what did you do different before?

Although I would rather write:
coroutine = StartCoroutine(WaitAndDisable(2));

[lofty mirage]

Also, I'm not sure what you're trying to achieve with this public void StartCoroutine() function

Isn't your end goal just to WaitAndDisable for 2 seconds?

[fickle stump]

nvm dind't fix it 😄

[lofty mirage]

In which case you would just write StartCoroutine(WaitAndDisable(2)) at the place where you want to WaitAndDisable 2 seconds

[fickle stump]

I'm still extremly new to coding so i'm just throwing paint at the wal and hope a masterpiece somehow comes int oexcistence

[fickle stump]

technically i wanted to edit waitTime in the editor, to test some stuff (removed the 2, was from a test earlier) but still I think I'm approaching my task the wrong way since it's not working like at all

[lofty mirage]

Yeah okay haha

[fickle stump]

My issue is, that I'm having a button taht i want to click to continue with an animation but during the animation (which is the waitTime) I want to disable some ui element. This way I though there's a clean transition from color to black and then again from black to color

[lofty mirage]

disable, you mean so that it's not "clickable", or cannot be seen at all (and not clickable)

[fickle stump]

the later

[lofty mirage]

oh okay

do you know where in code you want to trigger the disable coroutine?

Maybe your UI button OnClick() triggers a function?

[fickle stump]

doesn't the coroutine disable itself after waitTime?

yeah it triggers the StartCoroutine fucntion

[lofty mirage]

oh okay

well first of all I wouldn't call the function StartCoroutine()

because that is an in-built function name

so that may cause some problems

Maybe you can try:
OnClick() -> DisableButton()

using UnityEngine.UI;

private const WAIT_TIME = 2f;

[SerializeField] private Button myButton;  // you have to drag in the inspector

private void DisableButton() {
  StartCoroutine(DisableForTime(WAIT_TIME));
}

private IEnumerator DisableForTime(float waitTime) {
  myButton.enabled = false;
  yield return new 
WaitForSeconds(waitTime);
  myButton.enabled = true;
}

I just coded this on the fly on Discord for you

I think that should do it

don't forget using UnityEngine.UI

since I believe that you have a UnityEngine.UI Button element (?)

or is it just a gameObject?

if the latter, you can replace myButtonenabled by gameObject.enabled

[fickle stump]

so what I want to do isn't disable something temporary, but forever basically (if the player doesn't restart the level).
My intention is to waitTime, till the animation transition finished, then I'm going through two foreach loops: One to disable an array of Objects that shouldn't be active anymore after the anmation ended and one that enables objects that hsould then be visible

so I don't think disable button is the correct approach

[lofty mirage]

So you want to deactivate only after 2 seconds?

[fickle stump]

yes

[lofty mirage]

Maybe you can try:
OnClick() -> DisableButton()

using UnityEngine.UI;

private const WAIT_TIME = 2f;

[SerializeField] private Button myButton;  // you have to drag in the inspector

private void DisableButton() {
  StartCoroutine(DisableForTime(WAIT_TIME));
}

private IEnumerator DisableForTime(float waitTime) {
  yield return new 
WaitForSeconds(waitTime);
  myButton.enabled = false;
}

[fickle stump]

My button press:

• Triggers an Animation
• After x seconds disables ui

[lofty mirage]

so like this? (I updated DisableForTime)

you can replace the myButton.enabled by all the things you want to disable

here I put myButton data type because I don't know better your data structures

[fickle stump]

just game objects

so is setactive the wrong approach?

[lofty mirage]

SetActive() can work too I think

[grand snow]

to hide the whole button SetActive() is better
Otherwise changing the button interactable state is the other approach

[fickle stump]

Basically pressing the Button that's a child of Task_Front, disables Intro Anim and Background Black and trigger the Fade To Black Animation

[lofty mirage]

True, .enabled is more for components like spriteRenderers I guess

[grand snow]

yea thats right. It would "disable" the button but not change its visual state

[fickle stump]

i dont want to disable the button, but like everything .-.

[grand snow]

then do things to your parent container?

canvas group can be used to change the alpha of the whole object and its children

[lofty mirage]

Then like:
OnClick() -> DisableButton()

using UnityEngine.UI;

private const WAIT_TIME = 2f;

[SerializeField] private GameObject introAnim;  // you have to drag in the inspector
[SerializeField] private GameObject BackgroundBlack;  // you have to drag in the inspector

private void DisableButton() {
  StartCoroutine(DisableForTime(WAIT_TIME));
}

private IEnumerator DisableForTime(float waitTime) {
  yield return new 
WaitForSeconds(waitTime);
   introAnim.SetActive(false);
   backgroundBlack.SetActive(false);
}

What do you think of this @fickle stump

[floral garden]

Hi, i have a question , did a prefabs that need another instance like player component for it status or the gamemanager, it need to auto get it as yoou can’t drag and drop it in inspector

[grand snow]

You should set those fields at runtime using some other component
e.g. spawn player prefab, assign game manager reference

There are many ways to do it, the beginner way would be to use a find in the player component.

[floral garden]

The best way is to use a script to create that prefabs then assign the ref it need ?

[fickle stump]

omg

my code was working the whole time

[grand snow]

Yea, if you have something that spawns the player, it can initialize the player/set these important references right after.

[fickle stump]

i just fricked up the animation part

🤦

[lofty mirage]

oh okay lol

[floral garden]

It happens don’t mind haha

[lofty mirage]

Well it depends if you spawn the prefab during the gameplay or not

if it should be there since the start you can just drag and drog using a SerializeField

but if it's initialized during the game, then yes, you need to declare, initialize, and store the prefab in some variable in your script

[floral garden]

Nop, i try to make a dynamic spawn as it play on multiple scene but all my core systems is init only one time between scence change and at start but some is init later for optimisation

[lofty mirage]

okay then scripted all the way then

[floral garden]

Is it a bad idea if it set some variable itself ?

[lofty mirage]

wdym some variable itself?

You do use gameObject.function no?

function being whatever like .enabled etc.

[worn peak]

Would it be possible to make the start of an action depend on the keyframe of the animation? I wanna spawn a bullet at a specific time and was wondering, if I could use the keyframe of the animation to determine, when the bullet is supposed to appear

[floral garden]

Like trying to get the playerinputhandler that stored in the coresystem

!code

[teal viper]

Yes. Look up animation events.

What is your "coresystem"?

Like a GameManager?

[floral garden]

An instance that registe all other manager

Prevent multiple static instances

[lofty mirage]

What makes your PlayerInputHandler difficult to reference?

[floral garden]

It an exemple but here an exemple

(How we share code with past mod)

[grand snow]

if its a singleton then the player itself could retrieve the reference or just use the static field

otherwise as I said before, the class that performs the Instantiate() can also init state

[floral garden]

using System;
using UnityEngine;

public class NPCDialogueTrigger : MonoBehaviour

Thanks o7

[lofty mirage]

but sorry, I'm not too familiar with managing multiple scenes variables / objects at the moment

[floral garden]

Oh no problem

[grand snow]

I dont think there is more to say

[floral garden]

[lofty mirage]

Oh btw

I noticed you use the region thing

what is the point of it?

Just to click on region to "close" the visual for the code region in the IDE?

[dull grail]

Can someone give a direction where to look to make seamless 2d world like in Starbound, where player reach edge of the world and could just move forward without changing his position in code?

[teal viper]

It's likely that the world is broken into chunks that are placed dynamically, and when the player reaches the edge of the map, a chunk from the other edge is spawned.

And the player position is likely reset somewhere. Possibly on these edges.

[dull grail]

Thank you

[lofty mirage]

Yeah that seems to be the most likely

[rugged beacon]

    public static T CloneInstance<T>(this T obj) where T : class
    {
        var json = JsonConvert.SerializeObject(obj);
        return JsonConvert.DeserializeObject<T>(json);
    }

anyone has a better way of cloning a class instance beside creating a constructor with all the fields?

[fickle stump]

Someone got an idea how I can prevent clicking on UI, while a certain UI is active?

basically while my book is active, I don't want the user to be able to click on the buttons at the top left and the bottom right

[hexed terrace]

an image covering everything that blocks stuff you don't want to be clickable.

[timber tide]

disable the canvas raycaster is a quick solution

canvas groups I think have a sub property for that too?

[hexed terrace]

yep

[timber tide]

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/class-CanvasGroup.html

[fickle stump]

That's the quick and dirty solution

and i'm so gonna take that xD

[hexed terrace]

Making it black and giving it 50% - 75% alpha helps make it obvious too

For future reference - UI questions go in #📲┃ui-ux

[fickle stump]

Ah wait this is the coding chanel, my bad

U're right, thank you

[hot wadi]

What do u guys usually use OnGUI() and GUI skin for?
I find the Canvas system is way more efficient when it comes to many UI tasks

[sour fulcrum]

nothing

[grand snow]

no one uses ongui for game ui anymore

[sour fulcrum]

actually i lie

i use it for a little debug console built into my package because i didnt wanna mess with prefabs in a package

[grand snow]

if its not real game UI its okay.
UGUI or ui toolkit are the 2 choices

[sour fulcrum]

i wish it was viable tbh

i like it's ability to avoid relying on components

[grand snow]

well ui toolkit only needs a component to draw the ui document

[sour fulcrum]

i get why its great in fully fledged projects but i have zero interest in using ui toolkit rn because i (afaik) can't do it all in c#

[hexed terrace]

You can do UITK editor stuff all in C#

I do not know if that's the case for game UI with it

either way, doing it all in C# or with USS/ UXML(?) .. it's an awful lot of code

[grand snow]

you can build ui with code for both but its gonna be a pain, more so I think for ui toolkit

[sour fulcrum]

eh maybe im a freak but i don't mind it too much, maybe i haven't dabbled into the super crazy stuff yet

[hexed terrace]

It's been prob 2yrs since I was messing with UITK editor stuff, I remember struggling to get the right element.. had to keep going into the debugui builder thing and going down all the various trees etc

[silk night]

yeah as soon as you get more complicated UI you dont want to do it in c#

UGUI is perfectly easy to learn and use

UITK isnt there yet imo

[sour fulcrum]

I just hate how component pilled it is

[silk night]

component pilled?

[hexed terrace]

that's unity though - everything is components

[sour fulcrum]

Like a majority of it is heavily reliant on monobehaviours utilizing transform positions

[hexed terrace]

RectTransforms!

[grand snow]

ui toolkit probably did the right thing and stopped using a gameobject for each element

[silk night]

as carwash said they rely on rectransforms, also yeah cause monobehaviour is the way to script here and I dont get why you think its bad 😄

[sour fulcrum]

If you want to stray away from Unity's own collection of monobehaviours i think there's not too much your actually reliant on (couple colliders and renderers, maybe some physics stuff). with the UGUI stuff though it's heavily tailored towards that setup

i'd prefer to control a lot of that stuff in code directly

[silk night]

no not really, you can recreate basically everything from a button to text to scrollviews

you can even look at the code of how unity did it, its included with the UGUI package

[sour fulcrum]

It's a tough ask when you have to deal with topics like batching and font renderering, unless i have been missing stuff

[silk night]

then stop reinventing the wheel 😄

[sour fulcrum]

i mean sure but that wasn't my point 😛

[grand snow]

immediate mode gui is convenient to code but not really ideal for a game perf wise

so ideally you migrate to a supported ui solution

Unity would love you to use ui toolkit but i've yet to change

[hexed terrace]

Doesn't have world space UI yet, not possible for anything VR or AR

[grand snow]

yea not sure how thats not possible yet, even via rendering to some render texture

[silk night]

After going through the torture of using ECS when they announced it first useable and managed to make their own guide video obsolete after a mere 2 months and cancelling multiple solutions they praised in high tones to be the next big replacement, I dont touch new things in unity with a 10 foot pole until it has some adaption

[grand snow]

ECS has always puzzled me, they go to such amazing efforts to make c# be like a native lang and engine features seem to need whole new versions to even be usable with it

[silk night]

oh no the current version of ecs is fine and it makes sense they have to rewrite a bunch of engine features on the new coding style

but the way the handled the introduction was abysmal

[grand snow]

I've tried it but not had a big need to use it just yet. hopefully it improves more to be easily usable with most features

[silk night]

We currently still use the gameobject approach but our pathfinding runs on ecs in the background and then syncs the position to the enemies

[grand snow]

why not use burst jobs, seems like you almost are already

[silk night]

i mean its uses bursted jobs and data is handled on the ECS approach, its an entirely decoupled system from our normal code

[grand snow]

sounds like you have entities there for no useful reason but its working

unless they keep state re used all the time for pathfinding

[silk night]

yeah its not pathfinding that just runs once and we are done, its recalculating everytime the player walks more than 0.5 units and has local avoidance

[latent mortar]

Yes but I cant

[fickle stump]

ok i think i'm loosing it:
Shouldn't this literally toggle the object on mouse 0 click

[fickle plume]

No need to drag this out again. If you want to learn start with the link you've been provided, you can find comprehensive Pathways courses there.

[hexed terrace]

You can just do:

foreach (GameObject toggleObject in toggleObjects) { toggleObject.SetActive(!toggleObject.activeInHierarchy); }

As for why it's not working - add debug logs to find out if:

• the method is being called
• the foreach is running

[fickle stump]

what does this last part do?
!toggleObject.activeInHierarchy if it's not active in hierarchy I set it Active, but does it also disable it?

[sour fulcrum]

toggleObject.activeInHierarchy is a bool, ! "flips"/"reverses" the bool

if on, off
if off, on

[lofty mirage]

Well here you have a list/array of objects

if it's active, it's made unactive (and conversely)

imagine a flicker

but each flicker "tick" is a function call

[grand snow]

wha

it should work so its probably just not called to begin with

[north kiln]

either that or a parent is inactive and it's trying to toggle the child

[grand snow]

oh yea, danger of not using activeSelf

[fickle stump]

yeah i found the isuse i think but this just confuses me more lol. For some weird reason I can only toggle it from the top and not from the sides of the object oô

[grand snow]

those weird mouse events are kinda shit

its better to use a collider + event system + IPointer events

[manic sparrow]

when doing aiming from a top-down camera, do i make a separate script or do i connect it to the camera itself or the player its following

[fickle stump]

Whats funny is, if i zoom in the camera a bit, then it's no problem clicking on that cube

[grand snow]

yea that system is funny and I dont fully know its rules

[fickle stump]

Aparently it's because of cinemachines near clip plane beeing too low

[grand snow]

those monobehaviour mouse functions have nothing to do with cine machine

[fickle stump]

then i'm confused why it suddenly works after i adjusted the nearclip plane

lol

oh

i know why 🤦

I've put invisible triggers between the camera and the object to check if an object leaves my grid

and the ray from the camera constantly hit those triggers therefor i was unable to click on the objects, since they were behind the invisible trigger. Using the near clip plane the camera ignored the triggers infront and went straight onto the objects

[grand snow]

If you use the event system way you can specify the layers it uses

(requires a physics raycaster as well to work)

[fickle stump]

Ok kind of a weird question but are you able to access a prefab via script and manipulate it during runtime?
My idea would be to have two buttons which can change the material of the prefab that will be instantiated.

the problem why i can't access the to instantiate object is because I first render a third material on it

(actually I think i can just use the buttons and on button click increase the index of a count and depending on the index before instantiating, assign the material [index])

[silk night]

You can save the button state, and change the material on instantiate before you do anything else to it

but no, in a build editing a prefab would not be possible, the code for that is in the Editor assembly which is stripped during build

[grand snow]

thats not true. you can load the prefab asset and manipulate it but that will only survive till that loaded copy is GD'd

I dont know if unity re uses the same instance or not but probably a bad idea

[silk night]

Arent the methods for that in the editor assembly?

[grand snow]

you can load a prefab and modify the GameObject instance but its not actually modifying the stored state

[silk night]

Can you explain why that makes it impossible to access the object?

[silk night]

Ahh alright, yeah didnt think of that

sorry, misstyped "yeah" as "you" 😄

[grand snow]

tldr dont bother and modify the prefab instance post spawn

[fickle stump]

so in my head, if i click a button and it instantly assigns the material, then I instantiate the Object with a Transparent material and after mouseclick it should go back to original

now that i think of it

ah no the way it currently works is that its loading the materials again from the prefab

so i somehow have to tell the object that will be instantiated that after placing it (mouse click), it should instead get the material that i selected earlier but not sure how i would do that

[fickle stump]

besides that way

[silk night]

public class SpawnedObject : MonoBehaviour {
  public MeshRenderer Renderer;
}

public class Spawner : MonoBehaviour {
  public SpawnedObject Prefab;
  public List<Material> Materials;
  public int WhichMaterialToUse = 0;

  public void SetMaterialIndex(int i) {
    WhichMaterialToUse = i;
  }

  public void Spawn() {
    var spawned = Instantiate(Prefab);
    var spawned.Renderer.material = Materials[WhichMaterialToUse];
  }
}```

Just a simple example, then you just have to set the buttons up to use the SetMaterialIndex function

Unless I understood your problem wrong 😄

[hexed terrace]

public SpawnedObject Prefab;

This is the best way to spawn prefabs, don't declare them as GameObject - declare them as a component on the root, so you get a reference to that with the spawning.

[grand snow]

(unless using addressables where we cant 🙁 )

[shell sorrel]

depends on how you load things

[grand snow]

yea if you load the prefab then instantiate yourself it works

I dont get the benefit using InstantiateAsync() when the fuckers cant release themselves

[shell sorrel]

i find i do not use it often, also often i am not using addressable references either

since i am loading a bunch of stuff via a tag somewhere then doing stuff with it in the future

[hexed terrace]

you make your own addressable reference in that case

[grand snow]

yea its just an extra get component

as long as you remember to release the gameobject later its fine

[hexed terrace]

addressables are horrible to work with, if stored remotely - hate them

[grand snow]

Ops this local thing has a remote dependency fuck you!
The effort I had to put in to ensure this didnt happen was mad

[shell sorrel]

are fine no worse then assetbundles owrkflow for remote stuff

[fickle stump]

Just gonna ask for the sake of it

How much of beginner are adressables

Because this is the first time hearing that

[grand snow]

0 much is beginner

[hexed terrace]

They're not for beginners

Beginners won't be doing anything that needs them anyway

[shell sorrel]

its more a feature only needed to learn about when a game gets big or for production etc

[fickle stump]

Okay then i'll try avoid to do that and work wuth the basic first

[shell sorrel]

it will jsut add confusion learning it before having a good grounding in other stuff

[fickle stump]

Altight cheers, gonna steer away from them for now then

Maybe in 1-2 years

[fickle stump]

Something like this is what i thought if aswell ye

Thats what i tried to communicate hahs

Actually a good question actually, when would you consider people not beeing beginners anymore?

[silk night]

Being able to build a game without learning a fundamental aspect of unity (like "how do physics work?")
Ofcourse you will have to look up details or ask questions, I do even with ~7 years of experience but that never stops

[shell sorrel]

really things are large enough no one will be a expert at every part of unity

[rocky canyon]

imo ur always a beginner in certain aspects.. theres things you'll do more often then others.. and some things you may never use

mixed bag

[silk night]

Whenever I have to look at shadercode I feel like a programming toddler again 😄

thank god for shadergraph

[shell sorrel]

thats just practice, its mostly just very easy math

[silk night]

yeah I wanted to learn it but then unity dangled that carrot named shadergraph in my face and I never bothered 😄

[shell sorrel]

yeah i sometimes use it, but for this project its all HLSL shaders since shader graph was just getting in the way

[grand snow]

ooo scary shader code!

fixed4 frag (v2f i) : SV_Target
{
    float2 uv = i.vertex.xy / _ScreenParams.xy;

    fixed4 col = lerp(_Colour1, _Colour2, 1 - uv.y);

    return col;
}

Its worth being able to write shader code as some things still need that

[silk night]

i mean i can read it if its that easy 😄, writing it on the other hand...

[grand snow]

though be warned, urp/hdrp lit shaders will make you go mad

[shell sorrel]

yeah current game is using heavily stylized shading

[fickle stump]

I don't think I'll ever try this type of stuff LMAO

[shell sorrel]

so i more or less wrote the whole lighting model in a few includes so it can be called from shaders in a simlar way as the surface shaders of the past

[silk night]

good thing you dont have to, for small projects shader graph is perfectly fine, larger projects have dedicated graphics programmers

[rocky canyon]

might as well be alchemy to me.. (atleast for now)

[shell sorrel]

even know i prefer writing shaders in code now, learning with the graph i think is best

you get to see the output for each and every step which is huge when learning it

Shaders can seem difficult at first as its different vs cpu code

only thing ill have to stick my nose into is compute shaders

really i think most people just treat it like this weird black box and never look at the details

I guess you can but you need to understand at some point how the end result is being produced by a shader 🤔

Ofc simplest is uv -> sample texture -> output color

[shell sorrel]

now things get complex due to complex problems to solve not the shader part its self, like a full PBR lighting model is alot of stuff write and learn

where like ramp shading, cel shading or like a lambert+blinn is like 100loc of hlsl or so

[fickle stump]

Fun story: kinda sad but I'm actually a game deisgn student and i hope pray that I'll land a position in the industry as a leveldesigner and right now I also try to stick my nose into a bit of coding, just to understand everything atleast a little bit c:

(and ofc i have to submit projects for uni, so i kinda have to code)

[hexed terrace]

How long have you got left?

[fickle stump]

1 1/2 years

[shell sorrel]

good you got some time left, hopfully the industry will rebound by then

[fickle stump]

1 year was everything non game related, then had two semester/courses for game related stuff, then an internship at a completly different branch cuz yey internships and now two larger projects and my bachelores and I'm done

[fickle stump]

I mean, I have a stable job as QA and I don't intend on instantly leaving that position just because I graduate. Loving to work with these people and their proejct is insane

The leveldesign thing is just something I always wanted to do at some point in life. Doesn't have to be in the next 2 years or sum

[shell sorrel]

so QA into design is fairly common

[hexed terrace]

I think it's gonna take longer

[shell sorrel]

problem with design is most studios do not need many

[fickle stump]

and here I'm getting told so many ppl need leveldesigners

[shell sorrel]

think large studios will not rebound for a long time, but i can see more like mid sized indie and AA starting up to fill a void in the near future. Hard to say, like a lot of talent was cut loose but also getting investment is very hard right now

[silk night]

where are you located? I see a lot of companies searching for game dev staff in berlin, except for devs itself, that role is overcrowded 😄

[fickle stump]

Germany o/

[silk night]

yeah well then you have the choice of berlin, munich, cologne and hamburg as the big 4 in game dev

Also if you are considering europe in general poland and netherlands are good places to be

[shell sorrel]

it is crazy how much stuff changes, like way harder to get dev jobs now, vs a decade ago i accidently got a dev job

[silk night]

Oh well, I could have noticed that, you are actually on my server that is for the D/A/CH region 😄

[fickle stump]

Kidna something that scares the hell out of me

literally as soon as im about to graduate theres an influx of people joining hte industry

[fickle stump]

Yoo no way i thouight your face looked familiar haha

are u guys gamedev in the industry or is efveryone doing htis as their freetime fun

[hexed terrace]

think large studios will not rebound for

Did this for fun for about 6 years while doing web dev, then got an offer from a game company and switched, doing it professionally since 2019 now

hi, my power went out mid coding and when i booted up the project it showed like the script references and said 'The associated script can not be loaded' and i've removed the script from the objects and tried to add it again but it's not on the list, the name of the file is the same as the class name so idk what's the problem

[thorn imp]

is there a max size for native arrays? when i make my native arrays too big they seem to break. idk if its an issue with my code or native arrays start to break with too much memory stored

Probably the meta file didn't save. Easiest way to fix it would be to just make a new script, copy the stuff over, and delete the old one

oh, that's right.

Oh that'd do it

[summer shard]

why did i try to abstract it tf?? thanks

[silk night]

I mean pickable is a very generic name, could have been that you planned to make different ones with different behaviour, then abstract would have been totally fine as you would be able to use the inheriting classes

as you made the properties protected it seems like some kind of inheritance was planned

Does unity hierarchy not saved by a git normally? I've made a lot of mistakes and decided to regenerate project from git but now i see empty hierarchy

hierarchy is part of the scene, so did you save the scene and commit it

or did you open the correct scene again after getting the project from git again

[frail mango]

i'm feeling pretty stupid, how can I refine the position of my object?
When I target the tile I want to place the pointy arrow thingy at (mouse cursor at that moment is at purple circle), the way I'm rounding off the MouseToWorldPosition values make it appear I suppose rounded off to the closest number (cuz math) which places the tile to the lower left of where I actually want it to be targeted.

Now I totally suck at math, which is obviously a very good trait for any programmer to have, but how should I go about actually placing it on the tile that the mouse is hovering over, rather than rounded off to the wrong spot.

The code I'm currently using is

Vector3 screenToWorldPos = Camera.main.ScreenToWorldPoint(new Vector3(Mouse.current.position.x.value, Mouse.current.position.y.value, Mathf.Abs(Camera.main.transform.position.z)));
transform.position = new Vector3(Mathf.Floor(screenToWorldPos.x), Mathf.Floor(screenToWorldPos.y), screenToWorldPos.z);```

using Mathf.Abs for the Z position because it's currently set to -10 and I didnt want the offset to be hardcoded whenever I change the camera position above the grid

the grid by the way, is just a tiled sprite

(i wont have access to my pc for the next 3ish hours or so so I'll be responding via phone)

[vagrant mist]

Is it bad practice for now to have an EnemyTypes script that looks like this...

public class EnemyType : MonoBehaviour
{
    public enum Types
    {
        Melee,
        Ranged,
        Tank,
        Flyer
    }
}

[polar acorn]

If this is the whole script, what's the point of it being a MonoBehaviour? Why wrap the enum in a class at all?

[vagrant mist]

idk, didnt know that was an issue, I was doing it to reference in my EnemyHealth script and EnemyPathfinding script to assign different health values and chase behavior without giving each enemy their own script or sharing the same stats

[polar acorn]

You can make a file that contains just an enum

[timber tide]

Use a namespace

[polar acorn]

it doesn't need to be inside a class

[rough granite]

Wouldn't recommend having a enum in a class as it restricts that enum to that class

[vagrant mist]

as in I would have to reference that class each time I wanted to access the enum?

[vagrant mist]

do you mean in vs? or like just a different file type

[rich adder]

they are constants so it becomes part of the class

[rough granite]

Well as in if you wished to use the enum in another class and declared it there they wouldn't reference without being their numerical values

[rich adder]

eg EnemyType.Types.Melee

sometimes it makes sense to only keep within a specific class, sometimes it doesn't

[vagrant mist]

so it would only let me access with like 0,1,2,etc instead of what the name of the class actually is

[timber tide]

namespace Entity
{
    public enum EnemyType
    {
        Melee,
        Ranged,
        Tank,
        Flyer
    }
}

namespace Entity
{
  public class Enemy: Monobehaviour
  {
    [SerializeField] private EnemyType enemyType;
  }
}```

[polar acorn]

I mean in the script file you are editing, there is no point to have a class in that file at all

The file can literally be just the enum

an enum is a type, it doesn't need to be in an outer scope

[timber tide]

I'm lazy I just stick it in global usually

[vagrant mist]

why an enemy class in the file with the enum? is that the go-to way to be able to reference it from another script?

[rich adder]

being in the same file doesn't make any difference

[timber tide]

Doesnt matter if it's in the same script, but you can have that in a different script

Monobehaviours however do require to be in different scripts and SOs

cause Unity

[rich adder]

yea the only thing Unity cares about is not putting Two MB or SOs in the same file

[timber tide]

As in no two monos

[polar acorn]

That's an example of how to use it, not something that should be in the same file

[rich adder]

imo in the same file is poor organization

[timber tide]

Nice to have a EnumUtility script, otherwise nesting them

[vagrant mist]

I dont have a general Enemy class script atm, just separate ones that handle their health, pathfinding, and damage individually.

how would I assign one of the enums to different enemy Objects?

[grand snow]

components are good but i would not go that granular myself

[polar acorn]

You would create a variable of your enum type and set it to the value you want.

[vagrant mist]

so like in the EnemyHealth script, I would put

enum Types types;

then

types = 

[rich adder]

no
enum keyword is only used when defining the enum

[rough granite]

you know i feel like this answered it pretty well https://discordapp.com/channels/489222168727519232/497874004401586176/1401962939409367162

[rich adder]

the Types enum becomes the type

[polar acorn]

This shows both how to define an enum, and how to create a variable of the enum type

[vagrant mist]

so just replace the keyword with public or private in whatever script I want it to reference

[vagrant mist]

[SerializeField] private EnemyType enemyType;

is an example of how it would look in a script

correct?

[polar acorn]

Yes

that would be creating a variable of type EnemyType and assigning it the name enemyType

[rough granite]

me when this is exactly what the script above showed

[polar acorn]

It currently does not hold a value

You would need to assign it, probably in the inspector

[rich adder]

and when not assigned, by default the first item is used.
so by default enemyType would be Melee

Value types are never null

[polar acorn]

Right, my bad. I wanted to emphasize that declaring it is different than assigning it and chose my words poorly

[vagrant mist]

can you just drag and drop the enum file in the inspector and assign it there?

[rich adder]

You don't assign scripts to it. Its not a reference

its like saying , do I need to drag the integer class to assign public int myNumber

[polar acorn]

The enum file does nothing other than exist

You don't drag it anywhere

It allows you to create a variable of that type in other scripts

[vagrant mist]

then I'm confused about this

[polar acorn]

Try it

Put a variable of that type on a script

then look in the inspector

[vagrant mist]

alright

[manic sparrow]

do you guys have any guides to recommend regarding learning scriptable objects, monobehaviors, game objects, their differences and discerning when to use what?

[vagrant mist]

I can assign the enums, that was so difficult to comprehend for the first time

Monos require game objects, scriptable objects do not.
Monos exist in the scene or as a prefab in your directory, SOs can only exist in your directory or inserted as a property into a game object

I'm making a first person games using cinemachine. I am making it follow the player by doing this > vCam.transform.position = transform.position; this works but how can I change the Y position? when I press play it changes the Y position.

[rich adder]

you have to create a new vector3 and move the y as needed

var targetPos  = transform.position
targetPos.y = whatever;
vCam.transform.position = trargetPos``` or 
`vCam.transform.position  = transform.position + new Vector3(0, yOffset, 0)`

I thought Cinemachine already had such components you can play with offsets though 🤔

Game development isn't easy to be honest. It groups together a lot of different skills and depending on what your expectations are, it can be quite easy (less than a month) or very difficult (five or more years).

[fleet prairie]

I have a farely easy game idea in mind nothing to happening but just some fun co-op game

easy on the perfomance

nothing to high-fidelity

its sort of like a backrooms type game

with a few unconvential gimmicks

[foggy yoke]

co-op?

you mean multiplayer?

[fleet prairie]

yes

[foggy yoke]

yep

that'll take you years

im joking

but multiplayer is REALLY hard

[fleet prairie]

Iam curenntly working on a prodecurally generatred maze atm

and liek I created a simple fps character sript

following a video

[keen onyx]

i managed to learn how to use unity and create a game in like 8 weeks using chatGPT it does help to learn fail and try again until it works

[fleet prairie]

had to skim though like 5-6 videos to get actuall understand it

but when I did it was so satisfying

[fleet prairie]

oh

scared me there for a bit

[foggy yoke]

I think you shouldn't start with a fully fletched multiplayer game.

[fleet prairie]

noted

so I first go with a singleplayer

right?

[foggy yoke]

I would

but that's my preference

[fleet prairie]

I mean not gonna lie thats actually a good idea

[foggy yoke]

you could tackle multiplayer

[fleet prairie]

first comeplte the game on single player

and then transition to multiplayer

never thought about it like that

[foggy yoke]

yes, but once again, multiplayer is REALLY REALLY hard to make

[fleet prairie]

Ig it iss since making a singleplayer one is hard as it is

[foggy yoke]

if you want it to be polished, then yes, it is, but when you get the hang of it, it's simple.

[keen onyx]

hey if you don't mind me asking have you created a game for phones befor?

i didn't

ChatGPT and ai in general is garbage for education and I highly recomend avoiding it in the future

[late phoenix]

Does anyone know why this keeps showing up, im kinda new to Unity.

[sour fulcrum]

Just learn yourself with google and learning resources.

[fierce crow]

so im following a tutorial about how to create a action system and these are the two functions to subscribe and unsubscribe Action delegates to a static dictionary and in the tutorial they are putting a wrapper function on it.
the problem is I'm not sure if the "wrappedReaction" in the subscribe and unsubscribe function are really equal and subs[type].Remove(wrappedReaction); will work or not

[timber tide]

Well, have you tried it?

Tutorial really trying you save you line space that's for sure

[fierce crow]

actually it's me trying to save line space because i'm not familar with these kinds of syntax. and yea i should probably try it before asking :(

[frail mango]

anyone?

[timber tide]

So what's the problem? If the values are off then by what amount?

Alternatively, instead of using ScreenToWorld, you could just make yourself a large quad collider as the grid you raycast upon, or use Plane

[subtle sedge]

if i wanted to create a game similar to paper mario i would have to use unity 3d version right?

[timber tide]

ye, but secretly Unity is always 3D anyway

[frail mango]

well, it's rounding off to the closest integer, so it makes sense

here's a shitty phone recording

[timber tide]

start debugging the values you get back

[fierce crow]

Ok it doesnt work that tutorial made a mistake. i still don't know why tho

[subtle sedge]

true

i moslty make 2d stuff tho

i really want to recreate pokemon black and white in unity tho

but i have to learn 3d stuff ;-;

[timber tide]

3D is easier than 2D

[sour fulcrum]

wont be able to talk about that too much here btw 😛

[frail mango]

i mean the values are just rounded ints but it's agressively rounding 'em down I suppose

[subtle sedge]

rip

[subtle sedge]

really? oh

[timber tide]

To me just looks like some grid alignment issues without seeing values, but what you're doing in the code doesn't seem incorrect. I can just imagine that ScreenSpaceToWorld may be giving some wrong values

[viral flax]

Quick question, what's the best way to fire ray-cast from inside a trigger (collider) and still hit it?

For instance, you have a trigger representing Water, and you get different reaction from shooting at it and from within it.

[timber tide]

Usually I do some overlap method when I do some like shapecast in case of spawning inside of a collider, but I don't recall having problems with raycasts for that?

Now I question if overlap would work if it doesn't intersect at all

https://docs.unity3d.com/ScriptReference/Bounds.Contains.html
That may be the solution

[rich adder]

rays by default dont detect the inside of collider but you can enable

https://docs.unity3d.com/ScriptReference/Physics-queriesHitBackfaces.html

[timber tide]

https://docs.unity3d.com/ScriptReference/Rigidbody.SweepTest.html
Rigidbody has a sweep too

[viral flax]

I should probably mention that In this case it's a 'blind' cast, so I am not casing against any particular entity, I am only testing if something gets hit by the raycast; generally a collider.

[sour fulcrum]

why

[rich adder]

maybe they're doing a laser alarm that goes off when object goes in it 😛

[viral flax]

I gave one example. Another is for instance a ladder trigger - the player presses USE on the ladder and attaches themselves to it. Once inside, they can dismount by pressing USE on the same ladder, but if I'm already inside the trigger, I will never hit it with a normal raycast.

[sour fulcrum]

but why do you need to raycast while your inside the ladder

[viral flax]

How else do I detect what object is the player looking at? I'm looking for reliable methods for this exact purpose.

[sour fulcrum]

when you are on a ladder

do you want to know that the player is technically looking at the ladder trigger collider

[viral flax]

Well, ideally the collider and the ladder trigger are the same thing. Of course I can offset the collider or add additional entity for no reason, but that's just bad design - it's incredibly easy to create discrepancy. Of course, the representation of the ladder is different from the ladder trigger.

[timber tide]

when you enter the ladder you'd probably want to subscribe to it with OnTriggerEnter so this way you know you're inside of the collider

[sour fulcrum]

Well, ideally the collider and the ladder trigger are the same thing.
What do you mean by this? That also doesn't really answer my question

[timber tide]

as long as you're subscribed you know you're inside of the collider

otherwise it seems bounds is the idea, otherwise nav's idea of backface checking but it means your ray must intersect completely

[viral flax]

It currently works similar to HL2 in my case. You can either attach yourself to the ladder if you interact with it from a distance, or by jumping/touching it. That's just the way it is designed, and I only need the simple operation of detecting what entity the player is looking at, including if they're inside the collider.

It's not a matter of debating the design, but finding ways of raycasting from the inside of a collider and hitting it.

[sour fulcrum]

in source players are not inside the ladder collider

[stark prawn]

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            Debug.Log("Jump!");
        }
    // Fly ??
        
        float moveSpeed = 40.0f;
        float dt = Time.deltaTime;
        float dy = 0;
        if (Input.GetKeyDown(KeyCode.Alpha8) == true) 
        {
            dy += moveSpeed * dt;
        }
        if (Input.GetKeyDown(KeyCode.Alpha2) == true)
        {
            dy -= moveSpeed * dt;
        }

        // float Vertical = 0f;
        // if (Input.GetKey(KeyCode.Alpha8)) Vertical -= 1f;
        // if (Input.GetKey(KeyCode.Alpha2)) Vertical += 1f; 
        // 
        // transform.Translate(new Vector3(Vertical * Time.deltaTime, 0, 0));
        
    }
}

[sour fulcrum]

they are snapped onto the face unless im mistaken

[timber tide]

https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html

[viral flax]

You are mistaken. There is a trigger.

[sour fulcrum]

i am aware there is a trigger

[viral flax]

Good. That doesn't have any relevance to the problem. I will try to search for the answer elsewhere.

[sour fulcrum]

okay..

[stark prawn]

but i wanna add the functions of the manager to buttons which is in main scene

[sour fulcrum]

(was relevant)

[timber tide]

sure, why not? Whichever scene you want the manager in you tag it with DontDestroy, so next scene you load it will carry the manager with it

[trim burrow]

    {
        if (slowedDown == false)
        {
            Time.timeScale = time;
            slowedDown = true;
            Debug.Log("sloweddown");
        }
        else if (slowedDown == true)
        {
            Time.timeScale = 1;
            slowedDown = false;
            Debug.Log(slowedDown);
        }
       
    }

        (This is inside an update function)
        if (Mouse.current.rightButton.wasPressedThisFrame)
        {
            SlowTime(0.1f);
            slowedDown = false;
        }```

Why dosn't the debug message show up in my console when i right click? The time slows down correctly but for somereason i dont get the debug message

[timber tide]

but if you have references to the main scene on scene change it will lose them on the manager

so if each scene has unique data for the manager, then maybe making a unique manager for each is the idea

[stark prawn]

but i cant add the functions of the scene manager that in another scene

[timber tide]

right, so manager each scene it is, otherwise you need to dynamically link it all at runtime

ex. change scene -> level scene gameobject on awake call thes scene manager and binds itself to it

[stark prawn]

I wanna add a function of the scenemanager in game scene but in gamescene i have no scenemanager game object. So i cant add it manuelly that is the problem. is there any good solutions besides adding each scene a manager

[stark prawn]

i didnt understand

[timber tide]

what needs to be added to the scene manager on scene load

[stark prawn]

when i load another scene i want to use the same scene manager for the other scenes scene changing button

[stark prawn]

wdym

[timber tide]

public class SceneChangingButton: Monobehaviour
{
  private void Awake()
  {
    SceneManager.ChangeButton = this;
  }
}```

that's the dynamic solution for 1 scenemanager singleton with DontDestroyOnLoad

[stark prawn]

what does changebutton mean

[timber tide]

"other scenes scene changing button"

[stark prawn]

ohhh

[timber tide]

Idk, any data you wanna bind, it needs to be done on scene load in awake. Just a solution, there's many others

[lament drum]

can somebody help me on this issue pls?

[stark prawn]

but i have more than one button in a scene

[timber tide]

well. gotta do it for them all then

[stark prawn]

i want to add manually

[timber tide]

or, just make a scene manager on each scene and drag those references on the inspector <--- easier

[stark prawn]

ok ill add scene manager to all scenes

can i ask one more question

i want to make a button from a sprite

but when i add component i cant click it

should i use ui for it

or is there any other way i can use

just sprite

[timber tide]

you need to look into how to raycast a spriterender

UI stuff already includes raycast logic, but if using UI doesn't make sense then you probably shouldnt

[trim burrow]

anyone?

[timber tide]

your unit logic seems fine so something else is off

[eternal needle]

this code doesnt actually move anything, its just modifying local floats

[lament drum]

oh

so to make it move my character I gotta call it inside? I thought I just needed to drag and drop the code on it sorry

[stark prawn]

i want to add a text on sprite square how can i add

[polar acorn]

Create a TextMeshPro object, likely as a child object of it, and position it where you want it to be relative to the sprite

[eternal needle]

im not fully sure what you mean by this, but your code is just not moving anything. the only part which could move something is commented out.
if you weren't aware of this, you should really start with some c# basics

Anyone knows how to chain multiple formatter together in smart string? For example, {0:formatterA():formatterB()} something like this.

[grand snow]

what is a smart string 😆

[wintry quarry]

What's the use case

I think they mean string interpolation

[grand snow]

you can use string.Format() to replace named placeholders such as {0}

otherwise yea with string interpolation you can provide a ToString() format str like you did kinda

If its mad just do .ToString()

$"{thing.ToString(Func())}";

[plain oasis]

Something like "Damage is {attack:math(+3.5*5):format(0.00)}" to display the actual calculated damage in the localization text.

[grand snow]

then you do need string.Format()

Unless the unity localisation can do extra functionality

[plain oasis]

https://docs.unity3d.com/Packages/com.unity.localization@1.5/manual/Smart/SmartStrings.html#formatters
the built-in localization can already do a single function. I made {attack:math(+3.5*5)} and {attack:format()} work. Not sure if it supports chained formatter natively.

[wintry quarry]

Yeah like Rob said something like:

string.Format(GetLocalizedFormatstring(Key), math(numbers))```

[polar acorn]

You could do the math in parenthesis, then do a .toString() formatter

[plain oasis]

Can not find the syntax in the documentation.

[polar acorn]

$"Damage is {(attack + 3.5*5).toString("0.00")}"

[grand snow]

string.Format() is easier as you know what you are getting

"Damage: {0}, other shiz: {1}"

and as its ordered it works good in translations

[plain oasis]

string.Format is C# right? I was trying to avoid coding directly to allow designer/translator to do that inside the localization file.

[grand snow]

the {0} tokens go in the actual string

[wintry quarry]

The code would be separate from what the designer makes

[grand snow]

they do have to know what they stand for

when ive used gridly i leave an example in the context column

[plain oasis]

passing {0} directly meaning {0} is the calculated result? Which mean I need to hardcode the calculation inside code?

[grand snow]

yea in code you need to provide what {0} is replaced with

if you want actual maths in string thats a whole other ball game

I recommend not trying to do that

[wintry quarry]

You can create a template scheme of your choosing but you'll need to write code to parse and replace things

[plain oasis]

I have already achieved that by writting a custom formatter for smart string.

Just not sure if native smart string can have chained formatter

[stark prawn]

i did it like that but the sprite is front of it

[grand snow]

you may need to change the render layer and or layer order

(on the tmp text)

[vocal urchin]

I'd like to be able to visualize systems when I'm making new systems or doing big refactors. Do yinz have any way you like to accomplish that? Any good tools?

[faint narwhal]

anyone know how to combine multiple splat maps together in a .shader file so you can add more than the 4 RGBA layers to your material? this is what I have so far as you can see in the screenshot but I'd like to add more layers but I need another splat map so that I have more color channels available to assign as a layer.

[grand snow]

#1390346776804069396 is the place to ask because you have to solve the problem of how to know what splat map to sample in the shader as well

[frail mango]

you've mentioned colliders to raycast, what about going with a tilemap approach instead? I'm just worried about performance issues down the line when I have 10k tiles with colliders on em

[rough granite]

so silly question but is there a way to keep two value types from different class to equal each other without needing to call it in update each frame? ie keeping the float playerHealth to equal the CurrentHealth in the other playerHealth = StatsController.CurrentHealth;

[grand snow]

nope, you have to either copy the value when the other changes or keep it in some class that both objects can reference

float is a value type so always copies

[rough granite]

this feels kinda inefficient though

[grand snow]

yea it is so you should stop 😆

its also going to give you bugs and problems, how do we know what value is the "real" one?

have this data be kept in a class instance that multiple things can reference

then its a non issue

[sour fulcrum]

This yearns for properties

[rough granite]

fair, just noticed it while trying to rework some old code from my first game

had no clue what i was doing even though this was only 10 months ago

[rough granite]

if that is "bad" for you look what i've got in the other class (luckily only called once on start)

[sour fulcrum]

with properties you can do

PlayerHealth { get => StatsController.CurrentHealth; set => StatsController.CurrentHealth = value; }

Then you can touch PlayerHealth like it’s a field but it’s actually two functions in disguise that just point to/forward the statcontroller value

[rough granite]

does this update PlayerHealth if CurrentHealth was changed? and what about vice versa where if PlayerHealth was changed would CurrentHealth update?

[grand snow]

a property with a get and set is not a variable

its a fancy getter and setter function

[rough granite]

it isn't? TIL

[sour fulcrum]

With this PlayerHealth wouldn’t actually be a value. It would look like one when referenced in code but it actually just points towards another value

[grand snow]

but is used like it is a field
auto properties are the same but have a auto made backing field they set and get with

[rough granite]

what's the => do in this case

[polar acorn]

Properties are a pair of functions in a trenchcoat pretending to be a variable to get into an R-rated movie

[grand snow]

short hand for

get {
  return foobar;
}

[sour fulcrum]

You define a get for what happens when you want to read from a property and you define a set for when you want to write to a property

[rough granite]

does it matter that it's declared at the same time as when the reference for StatController is in the class? or no since it's not a var

[grand snow]

the getter and setter are just functions so it can do stuff with a class field (and other stuff a function can also do)

public float SecretFloat => secretFloat;
private float secretFloat;

[polar acorn]

It isn't really "declared" anywhere. It's not a variable. You define the functions that get run whenever the property is accessed or modified. If the StatController is initialized before either of those are called, it won't be a problem

[sour fulcrum]

Remember there’s only 1 actual value being stored in this suggestion, the one in StatsController

if you talk to PlayerHealth in anyway you’d actually be talking to StatsController.CurrentHealth

We solve the problem of you syncing 2 values by just having 1 value accessible from two different points

[grand snow]

back to the actual topic, you can keep the data in a class instance and use it via that or declare a property to "aid" in using that to avoid doing that weird copy in Update() @rough granite

check the docs for more info about properties if needed 📖

[rough granite]

will do, another question though SO's can there only be one instance of them in a scene like static classes or can i make multiple instances?

[polar acorn]

Each file on disk you've made from an SO is one instance of that SO

it lives in a file rather than in a scene

[grand snow]

and you can reference a scriptable object file as much as you want

[rough granite]

so if i wanted to reference a SO class would just giving it's name work or do i need the specific instance :?

[floral garden]

damn why in the update ?

[grand snow]

err

[rough granite]

cause this was like week 3 of learning to code :/

[polar acorn]

You would need a reference

[grand snow]

I sense miss understanding 🙏

[polar acorn]

Probably.

[rough granite]

probably lol

[floral garden]

3 week???? of learning code ? then fine , don't mind me

sorry

[rough granite]

well this was ages ago been about 11 months since i started now but trying to fix all my mistakes

[grand snow]

scriptable objects are a way to define a new asset type with data you want, just like a material or model or texture

[floral garden]

oh I see

[floral garden]

SO what a great creation

[rough granite]

what would the best way of having a single instance class that doesn't need to be strictly referenced by using, but can be used by many different classes (and not static) [SerializeField] StatsController StatsController;

[polar acorn]

Sounds like singleton

[rough granite]

totally had the wrong idea of them then whoops :/

[rough granite]

is this another Inheritance type?

[grand snow]

you can probably just have a normal class to hold these stats

[floral garden]

I forget what is a singleton

a static instance ?

[rough granite]

do you mean like no inheritance :?

[polar acorn]

https://gamedevbeginner.com/singletons-in-unity-the-right-way/

[grand snow]

If all it does is store some numbers it does not need to be a MonoBehaviour or be created as a scriptable object

^ the singleton pattern is good but more applicable for a MonoBehaviour

Perhaps a class to hold stats is used AND you have a reference of it in a singleton game manager?

[rough granite]

it does have functions in it that get called but yeah mainly stores values that are meant to be accessed easily

but does having it as a basic class limit it to one instance :?

[grand snow]

no?

[rough granite]

:/

[floral garden]

whut ?

[grand snow]

Learning c# only with unity can lead to these weird thoughts 😆

[sour fulcrum]

MonoBehaviours are base classes with a couple layers of inheritance stacked up on it

[rough granite]

shh i learnt java first then skipped learning straight c#

[sour fulcrum]

base class -> Object -> Component -> Behaviour -> MonoBehaviour

[floral garden]

oh

[grand snow]

c# properties are basically microsofts solution to the getter and setter functions java loves soo much

[floral garden]

learning something new

[grand snow]

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

but everything can be an object

[rapid laurel]

guys, can someone help me? I am making my first game, I added a Character Selection screen, but when I load the player character into the game, while the character is walking it changes back to the default skin. How do I make the animation change according to the skin selected?

[floral garden]

i like this advice

[floral garden]

do you use sprite renderer our sprite resolver ?

[rapid laurel]

i am using sprite renderer

[floral garden]

then you need to change it if you change the default skin then you need o change the clip to as you are using sprite renderer

the best way is using sprite resolver + sprite library

https://docs.unity3d.com/Packages/com.unity.2d.animation@3.0/manual/SRComponent.html
https://docs.unity3d.com/Packages/com.unity.2d.animation@4.1/manual/SLAsset.html

i am working on it so i can't help you more

[rapid laurel]

okay, I will try! Thank you so much!

thank you for your time

[fickle stump]

Me handing in my exams like:

[floral garden]

what have you send ?

[fickle stump]

nawh :c
SO! Question: You guys think it's a good way to learn with books, courses or just start something and try working from there

[fickle stump]

A gif! Squidward kissing a piece of paper while looking completly exhausted

[floral garden]

it depend but the best ways is both together , learn something in the book and try to apply it.

theory and practice is 2 different thing

[nova kite]

Hey! Do you guys know of any great sources to not just learn about the SOLID approach but also understand how to develop your own logic to implement it? I really like it but having a hard time coming up with it myself.

[floral garden]

Experience

You need to understand how it work then you can implement it by yourself

Tuto is a way but in code, you have a lot of way to archive a fonction

Some more optimism, other more easily or shorter

[teal viper]

There are some YouTube videos that cover SOLID in details, but perhaps don't fixate on them too much. Don't make them the goal. Instead understand what they imply and how they can help make your life easier.

[nova kite]

How do I gain the experience if I don’t know how to implement it in the first place haha

Like I know the premise

And separation of logic

But it’s hard to visualize it and make the flow chart and diagram🥲

[rough granite]

when you try and implement something what are you thinking?

[nova kite]

I learned that so far, I understand the flow and everything, I only have a hard time designing it myself

[nova kite]

“What would be the most ideal approach for this”

And then everything I learned the past week mixes in my head and I’m like “should I use a scriptable object for this? Or an interface? A static? Composition inheritance instance?” And then I don’t know which to choose

[teal viper]

Well, this will come with experience. It's not something you can learn by reading or watching tutorials. Reading other people code can help, but the best way is trial and error while remembering the solid and oop principles.

[teal viper]

The rule of thumb is start simpler. Only introduce complexity if it's really necessary.

[rough granite]

not that my advice is the best but i think thinking of what you want to implement in a real world sense be it the physics or well whatever then putting it into practice in code rather than thinking of what it should be directly in code

[nova kite]

While I try I keep doubting myself and I’m like “wait is this true separation” “what actually needs to be separated” “could this be combined without violating the system”

But if it’s truly just experience I guess I’ll have to crawl through it for now🥲

[nova kite]

One example is jumping and fall damage logic that i was stuck on and running and stamina drainage, I wasn’t sure if to separate them or not but ended up making an interface IStamina then a script to handle the logic and finally a system script that “bosses it”

[nova kite]

So first plan then think of the logic and then code

[teal viper]

You should remember that there's no perfect code. Even the most experienced dev wouldn't write something perfect. Just write something that works. And iterate on it as you go(if there is a need).

[nova kite]

But I often gets stuck on the digram alone🥲🤣

[nova kite]

That’s the thing, I wrote a base movement system that worked perfectly but it got so messy with everything in one script dependent on each other and I got so overwhelmed that I dropped my project for a week because I knew that there is no way this is how I should do that

And then I learned all the advanced techniques and OOP principles

And it’s much less overwhelming this way I really like how organized it makes it in my brain

[rough granite]

yeah for example i spent a few days learning orbital mechanics for my game, and instead of just jumping right into the code i researched on things like keplers laws, and newton's gravitational laws.

[teal viper]

Well, then you skipped the "iterate on it as you go" step. This might involve refactoring to make the code easier to read, debug and extend.

[nova kite]

Ohh wow! You went as far as learning the physics for it too

[nova kite]

Yes haha I didn’t really know any advanced techniques before this week I just wrote everything into one MonoBehaviour lol

[rough granite]

it didn't go well 😭 i couldn't get them to do proper orbits (though i only spent like 2 hours a day for a few days)

[nova kite]

I feel you on that, I don’t even wanna touch physics or math logic for now🤣

[rough granite]

annoyingly enough it's hard to find just straight physics equations on google

[nova kite]

It takes me two hours just understanding reading code that implements physics calculations lol

[faint narwhal]

oh sorry I thought the .shader script would be considered code I'll make sure to ask in #1390346776804069396

[nova kite]

That’s true🥲

Would using GPT for SOLID logic only help?

Like spitting code at me to iterate over

[teal viper]

Basically just proceed with the implementation taking into account the things that you learned.
If you're stuck on something specific, you can always ask for ideas here.

[nova kite]

Oh I revamped the script altogether haha I copied all of them into legacy dupe scripts and I’m re building it from the ground up😅

I made like 13 scripts that handle things separately using interfaces

I love interfaces tbh haha

[teal viper]

There's no such thing as "SOLID logic". If you really did learn these principles, you should know that they are very abstract things and don't force and specific coding pattern on you.

[rough granite]

what's SOLID logic :?

[nova kite]

I meant like formula haha

Or structure

[teal viper]

Solid don't dictate any of this.

[nova kite]

I watched in a video that it was said in a way of like “not violate the rules of the solid system” something among those words

[teal viper]

They're just guidelines to keep in mind when you implement your own structure.

[nova kite]

Yes guidelines haha

I like it, it gives me like a base to go off of

Something to follow

So I don’t just free roam and make a mess

[rough granite]

oh is this why people put an I before their interface classes?

[nova kite]

Next I really want to learn Events and State Machines because I believe they will be helpful too

[nova kite]

That’s just to distinct that it’s an interface haha

I for interface

[teal viper]

No. That's just a naming convention. Unrelated to SOLID.

[rough granite]

well no i know that but i mean is this the silly principle that people use for why they have silly naming conventions such as the I for interface and _ for private variables or whatever

[nova kite]

I like the I but dislike the _ 🤣

[rough granite]

oh i see i miss read what the I stood for

[nova kite]

It lets me know what the blue print is and what no to attach to game objects

At first I disliked interfaces because I was like “I really need to make a whole script for like 10 lines of code?” But then I saw how much it organized everything

[cyan crescent]

Does anyone use Yarn Spinner here? How can I trigger an interaction dialogue using an action key without running it at the beginning of the game? Just played around with it yesterday and just started coding last week, any basic help would be appreciated.

[north kiln]

Probably best to just ask in their server https://discord.gg/r92DjJ6ehX

[cyan crescent]

Thanks!

[mystic flume]

i just finished learning vector3 and raycasting what should i do now

[rough granite]

try making something with it to prove you understand it

[mystic flume]

i've made many from scratch

[mystic flume]

I just want to know what i should do after that, or what i should learn.

[slender nymph]

rather than studying random topics, consider going through a structured course that teaches you the concepts you need to understand in a structured/ordered manner such as by using the pathways on the unity !learn site

[eternal falcon]

:teacher: Unity Learn ↗

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

[wintry quarry]

Make a game you want to make and learn whatever topic ends up being necessary for making that game

[lofty mirage]

It's really big to learn "on the fly" imo

motivationally speaking

[floral garden]

Makz a game depend what you want to make

[median mortar]

Hi guys, could there be an issue with the representation of eulerAngles in code?
I'm trying to limit the rotation on the X-Axis of my object by converting the presumed new rotation to euler, check if the rotation on X-Axis is greater than my desired maximum and clamp it. But when putting the values to the log, I can see that the value is increasing up top 90° and than decreasing, while Z is flipping from 0° to 180° whenpassing that point. Inspector gives me values between 0 to 180.

float XInput = inputVector.x * _config.RotationSpeedX;
float ZInput = inputVector.z * _config.RotationSpeedY;

Quaternion rotation = Quaternion.AngleAxis(ZInput * deltaTime, motor.CharacterRight);
rotation *= Quaternion.AngleAxis(XInput * deltaTime, Vector3.up);

Vector3 tmpRotation = (rotation * currentRotation).eulerAngles;
Debug.Log("Quat to Vector3: " + tmpRotation);
// Never reached since my MaxAngle of 150° is never reached
if(tmpRotation.x > _config.MaxAngle)
{
    tmpRotation.x = _config.MaxAngle;
}

currentRotation = Quaternion.Euler(tmpRotation);

Quat to Vector3: (89.03, 232.89, 0.00)
Quat to Vector3: (86.19, 52.88, 180.00)

[wintry quarry]

Using Euler angles for this is a nightmare and a bad idea

You cannot generally isolate a single Euler axis and do logic with it. All three axes are inextricably linked and cannot be treated in isolation.

[median mortar]

Any suggestions how to limit X-Axis rotation then?

I know that Quaternion multiplication isn't cummutative, so maybe reversing the order gives me the same values as the inspector

[wintry quarry]

Do not try to rely on Euler angles

Seriously

You're setting yourself up for sadness

[wintry quarry]

Yes, diligent and thoughtful use of Vector3.SignedAngle and Quaternion.RotateTowards

[median mortar]

Maybe defining a max rotation using Quaternions and comparing via Quaternion.Dot?
_maxXRotation = Quaternion.AngleAxis(MaxAngle, motor.CharacterRight);

Oh, RotateTowards could be helpful, forgot about that

[balmy vortex]

Does anyone here have a 3d player movement script for unity I could borrow?

doesn't need to be anything special, just something that works

[wintry quarry]

You could use Unity's own starter assets controller

[balmy vortex]

ya I tried using it but I couldn't figure out how to get it to work

[wintry quarry]

It works right out of the box

That's sort of the point

[naive pawn]

and please don't crosspost

[floral garden]

Crosspost?

[naive pawn]

posting the same question across multiple channels'

[floral garden]

Oh i see

[astral flame]

Hi everyone, I have a problem with my code. It doesn't detect the name of my other code. It says it was not found.

[grand snow]

Then that's either not the class name or its in a different assembly definition (so this class cannot access it)

[north kiln]

Show the declaration of the other class

[teal viper]

Looks like a different assembly

[north kiln]

It looks like it's in a different assembly

[grand snow]

Looks like CarControllerNPC is not detected as a class in the project (based on the colour of stuff)

probably "miscellaneous files"

[north kiln]

Could just be VS, check if it compiled in Unity

If it did, restart VS

[patent wedge]

i'm having this issue and it driving me insane!!! so i'm doing a boxcast for placing objects but for some reason the hit.point is slightly to the left?! here's my code

Physics.BoxCast(Cam.position, heldObject.GetComponent<MeshRenderer>().localBounds.extents, Cam.forward, out RaycastHit hit, heldObjectRot, RaycastDist, placeLayer)

but weirdly spherecast works?

[north kiln]

Use the physics debugger and see what's going on
https://unity.huh.how/debugging/physics-debugger

Also it is generally concerning to me when people name a mask "layer" 😭

[patent wedge]

btw it's what most tutorials i've watched call them, you probably should call them mask idk?

[grand snow]

you miss understand, a mask is a set of layers you want the boxcast to use

[patent wedge]

i looked at the physics debugger and the debug view is what i want but for some reason the hit.point isn't?

[floral garden]

[patent wedge]

the cube in front is where it's been placed.

[north kiln]

It's unclear where the hit point would be from that view, it looks like it hits the ground completely flat

Maybe it would make more sense to you if you placed the cube at Cam.position + Cam.forward * hit.distance

Which would be the centre of the box hit position iirc

[patent wedge]

ok that worked but that seems like it could have issues if the hit.point is offset?

[north kiln]

I'm not sure what you mean

[patent wedge]

i.e there an uneven ground and the hit.point is slightly to the left which could make the hit.distance be way off!

[north kiln]

I don't really get what left or right is, the box is casted against a surface in the direction, and the distance it travelled can be used to get the centre of the new box

[sour fulcrum]

why do you think the hit point is offset

how are you spawning that cube

[median mortar]

Finally got the rotation clamped, forget Euler and just cancel Input if necessary

private void SetRotation(ref Quaternion currentRotation, float deltaTime)
{
    float XInput = InputVector.x * _config.RotationSpeedX;
    float ZInput = GetZInputClamped();
    Quaternion rotation = Quaternion.AngleAxis(ZInput * deltaTime, motor.CharacterRight);
    rotation *= Quaternion.AngleAxis(XInput * deltaTime, Vector3.up);
    currentRotation = rotation * currentRotation;
}

private float GetZInputClamped()
{
    float input = InputVector.z;
    if (input == 0f)
    {
        return 0f;
    }

    float angle = Vector3.SignedAngle(Vector3.up, motor.CharacterUp, motor.CharacterRight);

    if ((angle > _config.MaxAngle && input > 0f) ||
        (angle < -_config.MinAngle && input < 0f))
    {
        return 0f;
    }

    return input * _config.RotationSpeedY;
}

[patent wedge]

i am literally placing the cube at the hit.point which is weirdly one, off-center and two, in the ground so i have to elevate it!
hit.point + (hit.normal / 2)

[sour fulcrum]

homie

[ivory bobcat]

It's likely to do with how you're placing the cube rather than the hot point

[sour fulcrum]

any chance the amount your offsetting the cube vertically also happens to be the same amount its going sideways? 😛

[patent wedge]

how?! obj.position = hit.point

[ivory bobcat]

Are you perhaps placing it not relative to the hit point or the hit point with some offset?

[median mortar]

Why are you dividing the Vector of hit.normal?

[patent wedge]

nope i checked, that was my first thought.

[sour fulcrum]

i mean

thats the problem tho

[patent wedge]

because rn, the hit.point is not at the center of the where it should be thats the entire problem!

[keen dew]

If that's the default Unity cube, its pivot point is at the center of the cube. So of course if you place the center of the cube at the hit point which is at ground level then the cube will be placed halfway in the ground

[sour fulcrum]

i haven't seen any evidence of the hit.point being wrong

[patent wedge]

look at the picture above.

[sour fulcrum]

yup

post the code spawning and setting the cube

the code from that screenshot

[patent wedge]

i did! but i'll do it again

if (Physics.BoxCast(Cam.position, heldObject.GetComponent<MeshRenderer>().localBounds.extents, Cam.forward, out RaycastHit hit, heldObjectRot, RaycastDist, placeLayer))
                {
                    Debug.Log(heldObject.GetComponent<MeshRenderer>().localBounds.extents);
                    if (Vector3.Angle(Vector3.up, hit.normal) < 75)
                    {
                        Transform obj = heldObject.transform;
                        obj.SetParent(null);
                        // obj.position = hit.point + (hit.normal / 2);
                        obj.position = Cam.position + Cam.forward * hit.distance;
                        obj.rotation = heldObjectRot;
                        heldObject = null;
                        isHolding = false;
                    }
                }

[sour fulcrum]

cool

i haven't seen any evidence of the hit.point being wrong

you are offsetting it wrong

wait huh

obj.position = Cam.position + Cam.forward * hit.distance;

what do you think this is doing

[patent wedge]

just scroll up please! it was a fix someone suggested i have already said i don't like it.

[median mortar]

I still don't get why you use hit.normal / 2.
hit.normal gives you a direction, you need to define a distance by multiplying, i.e. at least the half-height of your cube

[north kiln]

Your suggestion didn't make any sense, and your code misunderstands what the hit point is

[patent wedge]

that is what i was planning on doing but the issue is the hit.point being off center. (slightly to the left, spherecast is fine tho)

[sour fulcrum]

hit.point is not off center.

[patent wedge]

but mine is!

[sour fulcrum]

nope

[north kiln]

It's not off centre, the cube hits the ground and whatever the first place on the cube that hits is what's returned

Your screenshot had the cube hitting the ground flat, so that point could be anywhere on the bottom face

[median mortar]

You are doing a BoxCast, so the first part of the box that touches the normal sets the hit.point

[keen dew]

I think they expect the hitpoint be at the middle of the boxcast on the ground, at the red X. But it's at the blue X which is an arbitrary point because the boxcast hits the ground flat on

[north kiln]

Which is a large area that you're just saying is off centre because you don't understand

[sour fulcrum]

Unless im tripping I haven't seen any of their code that would actually put that cube in that spot based on that hit point though?

i agree with what your saying just curious

[keen dew]

#💻┃code-beginner message and #💻┃code-beginner message

[charred spoke]

Is the cube a child and perhaps the parent is being placed ?

[median mortar]

I would use BoxCast to see if something fits between stuff, not to spawn objects.
Do a Raycast and then an Overlap check for your box size

[north kiln]

My suggestion gets the centre of the cube. If they wanted the centre of the face that hit that's also possible, but at this point I'll be leaving instead

[patent wedge]

then why does spherecast.point work perfectly fine.

[north kiln]

Because a sphere doesn't have a flat face?

[median mortar]

Because a sphere has a smaller / not flat surface

[keen dew]

The sphere hits exactly one point, at the red X in the picture

[patent wedge]

no i just want the center of the cube.

[sour fulcrum]

oh right the normal offset would do that ye, forgot it only needs half a m up

[north kiln]

Then my suggestion was that.

[ivory bobcat]

The hit point isn't assigned by you but rather the physics system. It's value is that of where the point of contact was made. How you choose to use the data would be dependent on your needs. The point of contact (any point that makes contact - any point) is where the contact was made. If you're wanting the center instead, perhaps try raycast rather than box cast.

[grand snow]

🤦‍♂️

[sour fulcrum]

(i just wanna clarify even though it's totally valid to want the centre of the cube, that's not what the point of the hit is, hence confusion)

[north kiln]

This is the centre of the cube for a boxcast

[median mortar]

@patent wedge Do a Raycast and then check with Physics.OverlapBox if your Box fits at the hit.point.
If it doesn't collide with anything, spawn the cube

[patent wedge]

i'm just gonna stick with this. unless there's any better way.

[patent wedge]

i'm still confused what exactly is hit.point? and why is hit.distance not the distance from the origin to the point?

[ivory bobcat]

Any point where the two objects make contact.

[sour fulcrum]

if your driving and you hit someone on a bicycle the hit.point is where the car contacted the bicycle, not the centre of the car

[north kiln]

Distance is the distance the cast travelled, not the distance to the hit point

[sour fulcrum]

now if you drop a crate off a building onto the street multiple "points" on the bottom of the crate might hit the concrete at the same time

[sour fulcrum]

in this case the crate hit this corner of the ground "first"

[north kiln]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/RaycastHit-distance.html

In the case of a swept volume or sphere cast, the distance represents the magnitude of the vector from the origin point to the translated point at which the volume contacts the other collider

[patent wedge]

Thx everyone for your help.

[median mortar]

hit.point is the part of your cast (a box in your case) that touched the normal first.
But your box has a huge flat surface that hits another flat surface, so the first contact spot is floating in the noise region of your floating points.
Just rotate your BoxCast 45° on X and Z, you will get the same point every time since the tip of your cube always faces down

Use a Raycast+OverlapBox or something

[slow hollow]

I am pooling a bunch of meshes in and out of player view, I decided to disable/enable collider and mesh renderer, but as I do so but spikes seem to be bigger and profiler generally more dense on low amplitudes.

Is it generally a bad idea to disable/enable or am I just doing something wrong elsewhere?

[hexed terrace]

Toggling the active state is better than destroying/ creating.

Why are you toggling those components though? Just toggle the root/ parent gameobject

[slow hollow]

the root component runs other threads for calculations even while pooled away so i cannot, i just dont want the player seeing it coming back to view mostly and maybe get a slight optimisation in case unity renders things that are out of view

for collider im scared that i will spawn something that moves on it and it will roll away for no reason (while the mesh is reshaping) xD

[hexed terrace]

this is occlusion culling which Unity does for you

[slow hollow]

no no, it does my calculations while pulled away, i.e. pcg generating next heightmap etc, thats why i keep the parent active. when its back into view for reshape i make the mesh visible again, adjust vertices, calculate bounds etc

i was just wondering if its better or worse to actually use disable + enable. the implementation doesn't really matter tbh

[hexed terrace]

better or worse than..

[floral garden]

Pool system then ?

It better to do enable + disable than create/ destroy as it cost more

You can also load everything then disable it after, so you will not have the frame lag because of shader calcul

[slow hollow]

I already have a pooling system, when I pool them I disable when I unpool and modify enable

the alternative is clipping the camera so the player doesn't see that im moving chunks around

[ivory bobcat]

Of the two which is worse? The colliders or renderers? And enabling or disabling?
The two components (relative to name) sound like they would be doing some bit of work when disabled and enabled.

I'm assuming you've verified the performance with the Unity profiler.

[slow hollow]

They will do work anyway after unpool because renderer will have to display new shape and collider calculate new collisions. But does disable/enable have significant overhead?

[ivory bobcat]

Check the profiler

[slow hollow]

yes it's worse to disable/enable, but I wonder if it's my fault somewhere or this is default behavior

like, do others suffer when they do this?

[hexed terrace]

it's something you're doing

[ivory bobcat]

Check with the profiler instead of guessing.

[night raptor]

What do you mean by out of view btw? Unity always uses frustum culling so disabling renderers outside the frustum wouldn't do much

[slow hollow]

actually that's helpful to know!

[ivory bobcat]

Colliders, so they may be getting removed from the physics simulation

[night raptor]

Not that the frustum check is free but I would be surprised if the one unity does (in c++ I assume) is slower than yours

[slow hollow]

im not doing it to optimise im doing it to hide moving it in from the player for that 1 frame cz it looks a bit awkward, but i care about fps ofc so i ask 😄 im good now though

thanks

kinda gonna rush it because its for my thesis, I think im overthinking the smallest things

[night raptor]

I don't quite understand what you mean by that 1 frame thing but whatever, good luck

[slow hollow]

when I unpool many chunks, people can see them kinda move from poolposition to their position for some reason. Even though it's numerically a transform.position = new_position, for some reason it's a visible change like movement. disabling/enabling or camera limiting fixes that

[night raptor]

Never heard of that happening. If you immediately position the chunk when you enable it from the pool (not in that chunks update or something), there shouldn't be a frame rendered in the wrong position. You should look to actually fix that issue rather than working around it

[slow hollow]

I am talking without enabling it, the pooling is just moving it out of view and bringing it in when needed. There is no issue I think, it's just unity processing too much

[night raptor]

I again don't know what you mean

also pooling by moving out of view is quite odd, generally you would just deactivate the object so it would disappear from all the systems (rendering, physics etc.)

[vale lintel]

Is there any way I could get someone to watch me code and explain the basics? Complete beginner and YouTube tutorials aren’t doing it for me

[hexed terrace]

only for £££/$$$

Alright thank you

i am watching a tutorial from a couple years ago and i am running into a problem with this line of code. How do i fix this????

it doesnt like the top line

[sharp mirage]

i think u should say KeyCode.D in the brackets instead

[sour fulcrum]

have you googled that error

[frail path]

yea, was too confusing for me

i started yesterday

You are using the old input class, unity made a new input system. Your project is set to use the new one.
go to project settings > player to change it back to the old one OR learn the new input system (recommended)

yo guys how do i solve this

[naive pawn]

!install

[eternal falcon]

When Unity fails to install checklist

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

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

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

[solid oyster]

when i use the toggle box, the glow prefab switches intensity, but only when i select it in the project window, and it does not update the glow on my other prefab, even though it does when i change the intensity manually

what is going on?

also im trying to get the toggle to stay check wehn leaving the scene but im failing so far
