[pliant dome]

I swear I didnt mess with the code before I went to bed so idk

[frosty hound]

It's physically impossible for your game to have change, on its own, over night.

[pliant dome]

well yeah but I did have unity running while I was playing some games last night

so Id assume I pressed something that changes something

[frosty hound]

When it wasn't in focus? Impossible

[pliant dome]

without realizing

[frosty hound]

Anyway, you should just figure out the problem, rather than why it happened.

[sour fulcrum]

i cant think of any hotkeys no

[frosty hound]

How are you handling the jumping now?

[sour fulcrum]

this does sound like you don't have version control?

[frosty hound]

Check the values for it, if they're something you've tweaked before.

[keen dew]

If the code isn't framerate independent then having other programs running in the background might have made the editor run at a slower framerate

and make it behave differently

[pliant dome]

Just double checking but the gravity on the Y axis should be -9.81 right?

[naive pawn]

yeah

Hi everyone! I'm new to Unity and game development. I want to create my first 2D game for Android (it will be a RPG. What tutorials, documentation, or learning paths do you recommend for a complete beginner? Thanks!

[pliant dome]

Okay I can confirm that its not something in my code

Because I have a player 2 that hasnt been updated with all the new good code Imade for player 1

ITs def something within unity specifically like in the settings or inspector

[slender nymph]

can you elaborate on how this somehow confirms it isn't the code?

[pliant dome]

My player 1 uses a statemachine and its own controller scheme while player is super outdated code thats the most basic getkey code with very basic functions. Im very aware that these def work and I dont touch player 2 at all

So if player 2 is descending just as slowly as player 1. This most definitely means that its most likely a universal unity thing that I mightve done on accident

[slender nymph]

unless you've made a similar mistake with your logic. but we won't know that if you keep making assumptions and don't share the code

[pliant dome]

I guarantee you its not but dw about it

[slender nymph]

there's an easy way to prove it isn't the code (which it almost assuredly is), and that's by showing the code

[dry pulsar]

Can someone tell me why it is spawning 2Objects and not 1?

[swift crag]

Perhaps you have two copies of FlyingObstacles in your scene!

Otherwise, I see no reason for this to happen

GetKeyDown is only true for one frame, and Update runs once per frame

[swift crag]

to quickly check, search the Hierarchy for t:flyingobstacles

this will highlight every game object with that component on it

[rich adder]

there def is at least two

[dry pulsar]

I got it tysm guys

[swift crag]

i wonder if that counts two instances in a scene as one reference

(since that's one asset (the scene) that references the type)

[errant breach]

Hello ! So i have a small question regarding StateMachine.
Some logics, kind off..

So my enemy have a lot of states... Two of them being :

• Moving
• Tracking

When moving : The AI's go left and right, turn when touching a wall / getting of ledge, etc
When Tracking : The AI's walk toward the nearest player.

And im wondering how i should organise my Script... To walk, avoid hole, touching wall, i want to copy/paste the code from moving to tracking, but that would be ugly. I don't want to put too many code on my StateManagerHandler, so im wondering in your opinion what would be the most efficient way of doing that...
Thanks ! :)

[autumn verge]

i have some assets that only appear in vr mode

because they're tied to the controllers

basically its a series of lights

that are rendered ontop another asset

that is on the controller object

how do i locate the lights and adjust their position in space?

without needing to run the app in vr every single time

[cosmic quail]

the copy pasting code issue could be solved by having tracking inherit the moving class
that way you can freely use moving class' methods in the tracking class
(or have them both inherit a third class)

[rich adder]

why are moving and tracking doing the actual movement ? instead of just defining where destinations should be

moving state is a bit vague in itself you probably just want to define what its doing
ie. Roaming/Patrolling vs Seeking/Tracking etc

[errant breach]

I get your ideas.. Thank you for giving them to me ! Ill try to see what i can do ! :)

[brittle tangle]

I am using URP

[elder hearth]

Beat me to it lol

[brittle tangle]

when I set the "background type" under environment tab in camera to solid color

[naive pawn]

right, so as a single message please

what is the issue you're having

[brittle tangle]

when I set the "background type" under environment tab in camera to solid color and set the color grey I get weird rings

[solar hill]

rings?

Can you demonstrate with a screenshot

[naive pawn]

that's a solid grey screenshot

[solar hill]

those rings are color banding

i see them

[brittle tangle]

I don't want that I want flat grey

all grey

[short hazel]

You have a vignette post processing effect enabled?

[elder hearth]

Zoom in

[naive pawn]

ah i see them now lmao. that's really subtle. or my screen is shit

[solar hill]

the opposite

[elder hearth]

Had the same problem lol

[brittle tangle]

I don't have any post processing effect enabled. It only happens on grey colors and not on any other colors

[solar hill]

Theres a setting in called "HDR Color Buffer Precision"

try setting that to a higher value like 64 bits

i think the default is 32 so it could be causing the color banding

[brittle tangle]

under which tab is it?

[solar hill]

honestly i cannot even remember

i just know its a pain in the butt to find

[short hazel]

Seems like a bit depth issue yeah, might not be visible on other colors without checking with a color picker tool

(or increasing contrast on a screenshot using your go-to image editor)

Yeah there's like 2 bit differences between each color

(contrast adjusted)

[brittle tangle]

that only increases the number of rings

[solar hill]

well yeah

thats a good thing believe it or not

it just means its trying to blend more of the colors together

[brittle tangle]

wait i just realized

since i need flat color I can just use ui with a flat color as background

but that would block objects being on the screen

[solar hill]

it would not

is this a 2d game im pressuming?

[brittle tangle]

nah 3D but I need a flat background to highlight a sphere

[solar hill]

this sounds like an XY problem if ive ever seen one

how about you tell us exactly what you are trying to accomplish and how, and there might be a better solution out there

[brittle tangle]

I just need a flat grey background and a sphere

Like how you render images from blender

it's definetly something to do with hdr

since messing with the setting does something

nvm

vignette was on

[brittle tangle]

ur were right gang

[short hazel]

Oh well, that solves it, glad it's not some obscure bug or limitation of the engine

[hallow sun]

Using shadergraph, how can i use Image color only though code?
"Disable tint" completely shuts it off, meaning i can't get it through _MainColor
But not disabling lets it tint again after the shader's effects.

I'm making a progress bar that greyscales the texture where its consumed, but still want it to be tintable for the full part.

[grand snow]

Then you need to branch the colour to either be normal or greyscale (or lerp between normal/greyscale)

[pliant chasm]

(I hope this counts as beginner, since I am) I'm trying to get a movement system, and my current method involves actions increasing specific directional speed variables and Translating my player by each variable in their respective directions. however, this has the side effect of the object's rotation controlling trajectory in air, because the code just tells it to move forward relative to the player, so when the player rotates, the trajectory changes. is there any way to not have that happen?

[solar hill]

youre going to need to maintain a seperate velocity vector in world space and rotate independently from that

instead of constantly using the objects current forward/right vectors

can you share the code you have

[verbal dome]

If you are using Transform.Translate, it uses local space by default but you can pass in Space.World as an extra argument to make it translate in world space

[pliant chasm]

I thought about that, but that means I would have to find a way to save the exact trajectory values, no matter which way I'm rotated.

thanks! it worked out

[hallow sun]

is it bad practice to modify other variables in setters, like this?

private int _health;
public int health {
  get;
  set {
    _health = Mathf.Clamp(value, 0, maxHealth);
    healthBar.material.SetFloat("_Progress", health);
  }
}```

[teal viper]

It's not ideal, but if you document it, it's fine. I'd prefer an explicit method though.

One functional issue that I can think of is if you want to modify health at some point when healthBar or it's material don't exist, you'll get a null reference error.

[sour fulcrum]

yeah its not too big of a difference but i tend to do

private int _currentHealth //named current because i tend to have a _maxHealth
public int CurrentHealth { get => _currentHealth; set => ModifyHealth(value); }

private void ModifyHealth(int value)
{
  _currentHealth = blabla;
}

[swift crag]

i prefer to have my healthbars watch an entity

rather than the entity directly telling the healthbar to update

(this could be done with events, or it could just be done once per frame)

[swift crag]

after all, some enemies might not have a healthbar; others might have a fancy healthbar that behaves differently than usual

or maybe an enemy has 100 healthbars as a joke

[sour fulcrum]

I don't disagree with what your saying but I do think that starts to approach the "it depends on the game" point

[swift crag]

yeah – and if you do realize this is a problem, you can easily refactor

dlich just brought up a useful point: "hard-coding" something adds constraints to your design

of course, designing your game so that there are zero assumptions about anything is a recipe for disaster

where everything is so abstracted that you can't figure out what the game actually does 😁

[sour fulcrum]

Frl

Still highly depends on the game but this is one of the rarer examples where optimization stuff can potentially matter too since it's hitting ui stuff that updates often and might scale

[pliant chasm]

How would I move an object in relation to the rotation of another object? like say I had an object that is at rotation 90 degrees, and another at 0 degrees. how would I move object1 forward based on the rotation of object2 (so forward for object2, but left for object1)?

[steep bronze]

Hi guys lm new lma try and make models but ye

[naive pawn]

use the other's rotation in calculating the direction, you could also use the Transform/InverseTransform methods

[pliant chasm]

can InverseTransform, instead of switching from world space to local space, can it switch from the local space of one object to that of another?

[rough granite]

read the doc to find if it's got a method to

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Transform.html

[pliant chasm]

MUCH appreciated man.

(this isn't sarcastic or anything, genuinly thank you)

[winter monolith]

does anyone know any good beginner ui tutorials i want to make a stamina thing

[sage mirage]

Hello, guys! I see Dot() has two method overloads the first one takes Vector3 lhs and Vector3 rhs so I think left hand side and right hand side, but also there is another one which takes in lhs and in rhs. So, in which case do we use the first method overload and in which the second one, basically I know about the first one it is way to find the field of view of an npc for example if its 0 its perpendicular if its greater than 1 its in front of the player if less that -1 player at the back.

[naive pawn]

i don't think you really need to choose?

they do the same thing

The in modifier is required in the method declaration but unnecessary at the call site.
so you could get that second signature even without doing anything i think, if the first signature didn't exist

The in modifier enables the compiler to create a temporary variable for the argument and pass a readonly reference to that argument.
i think it's just a compiler/optimization thing
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/method-parameters#in-parameter-modifier

you don't need to worry about it

You can gain performance optimization by defining methods with in parameters. [...] Declare in parameters to specify that you can safely pass arguments by reference because the called method doesn't modify the state of that argument. [...] You explicitly add the in modifier at the call site to ensure the argument is passed by reference, not by value.

[sage mirage]

oh, ok. So, it is used to pass arguments by reference but keep them readonly. So, I assume if you dont have to change the lhs and rhs then you use in modifier, and I cant think in which case you would have to change them to tell you the truth.

In which case you have to change the lhs and rhs at runtime and this is another interesting question?

[naive pawn]

you don't have to mutate the parameters (you can copy them), but it's possible, so the compiler has to make that behave correctly

it does that by copying the value types

if you know you aren't going to mutate them, in marks them as such so it doesn't have to make the copy just in case

Is there a way to get the selected index of an array in the inspector, or whether the array is selected? I want to display different info depending on which index is selected.

[naive pawn]

[red rover]

Gotcha... I figured this was pretty far fetched lol. There's probably a way, but it'll be pretty hacky.

Hey, guys! Why characterController.velocity is read only?

rb.linearVelocity is not if we compare them

[naive pawn]

CC and RB aren't the same, perhaps...

[naive pawn]

https://docs.unity3d.com/ScriptReference/CharacterController-velocity.html
the docs say why

tl;dr: CC doesn't move with velocity. this one is computed from the Move that happened in the previous frame

[sage mirage]

So I have to use Move first if I want to use velocity right afterwards?

and it has to be assigned to a variable?

because its readonly

[naive pawn]

no? why would it need to be

[naive pawn]

what, do you want to modify the velocity?

[sage mirage]

No I just wanted to see if I can do something like cc.velocity +=

like I do with rb

[naive pawn]

so you want to modify the velocity

you can't, because CC doesn't move with velocity

[sage mirage]

yes I can use move by the way

Move()

[sage mirage]

oh

[naive pawn]

CC.velocity does not expose internal state like RB.velocity does, it reports what it did the last frame, caused by Move

[sage mirage]

oh ok so thats why it is readonly

[naive pawn]

that's what the docs say, yeah...

[sage mirage]

if it doesn't move with velocity then how it moves?

Character controller uses kinematic based movement right not physics based

right?

[naive pawn]

Move sweeps (to handle collision) and teleports, something like that

[sage mirage]

Heym guys! Normalize() and normalize are the same thing right? if I do moveDirection.Normalize() its the same as doing moveDirection.normalized right?

its just used in different context right?

[naive pawn]

one mutates, the other does not

(normalize is a verb, normalized is an adjective)

they both refer to the same concept of normalization, and both use the same math, but they don't do exactly the same thing

[verbal dome]

Dont remember if ReorderableList has that exposed but thats what I'd look at first. Also #↕️┃editor-extensions probably knows

(But yes, it is custom editor/drawer stuff)

[verbal dome]

You're supposed to keep track of/provide the velocity yourself, like pretty much every CC example shows

[wild fox]

does rigidbody2d variables not take .isKinematic anymore? It gives an error for me

[burnt vapor]

And what is the error?

[wild fox]

oh .isKinematic is just deprecated, it says the alternative func to use

[burnt vapor]

question, I have this script to run the enemy turn coroutine as many times as there are enemies on board, which currently works except that they all do it at the exact same time, even though the coroutine has several WaitForSeconds commands, including one at the end. How do I fix?

[solar hill]

is this script on each individual enemy?

[cosmic quail]

you're starting all the coroutines during the same frame. add a yield return waitforseconds after your startcoroutine(enemyturn(i)) line

[crystal agate]

okay its working thank you

[crystal agate]

its a singular battlesystem script

if the first screenshot is from a coroutine you could yield return the inner coroutine to wait for it to finish as well

It will print that every time that line runs

if you're getting multiple prints, you're running that line multiple times

[elder hearth]

It's getting called every frame, but what I mean is there would usually be a number next to it and that's how many times it was printed

Hey guys so I have little planets in a my main menu that randomly generate with a seed.
Not anything complicated, but they each have values like "planet size" which is an enum with 3 values.
When clicking on these planets I want to to load the level WITH these stats.
Since the stats are on these monibehavior planet objects I'm not sure how I can tell the next scene what values to use.

I shouldn't be able to use scriptable objects because each planet has random stats

[polar acorn]

You could put the options onto a DontDestroyOnLoad object, and have the things in that scene read the data from that object before initializing themselves

not entirely sure why that namespace would cause that problem though

[polar acorn]

Ambiguous reference exception

[slender nymph]

is it not a namespace from a library that isn't included in unity?

[swift crag]

I bet it has a class named "Transform"

huh, funny: it has a type named TransformBlock, but not just Transform...

A common source of this kind of problem is:

using System;
using UnityEngine;

...

float wat = Random.value;

System.Random and UnityEngine.Random are ambiguous here

you need to config your IDE first before anything

[light glacier]

How much do you guys rely on Namespaces? What I mean is: do you still make sure every class is named uniquely or do you rely on the namespace taking care of it?

Like imagine you could need multiple "ScreenController" classes.
Would you just always name it "ScreenController" but with a different Namespace or rather "XScreenController", "YScreenController".

I'm a little scared of namespaces now because I had twice the problem that the IDE was confused when a class had the same name.

[storm matrix]

Fixed it, the issue was a typo, I was supposed to use capitalized U in "Update", but I used a lowercase one

[storm matrix]

Good idea lol

[frail hawk]

we all saw that lowerCase u

a properly configured IDE would give you code suggestions and show you errors

[rich adder]

yes, a configured IDE would basically underline, offer suggestions, because its connected to unity and most of these have warnings

[storm matrix]

Yep, I made some adjustments, and added a few missing plugins

[naive pawn]

make sure every class has a unique qualified name (aka namespace+class name)
they need to be unique to be valid, and also if they're different, they should be named differently to reflect the differences.
the difference in naming could be provided via a namespace, or just more descriptors in the class name.

whether you use namespaces or just extra descriptors is up to preference and whether you need grouping of other classes within the same namespace as well.
X.ScreenController,Y.ScreenController and XScreenController,YScreenController aren't that different to read.

[light glacier]

Thanks Pekora

[swift crag]

I'd use the former if it's uncommon to –

[power goes out]

– use multiple screen controllers at the same time

that was annoying

(of course, you can also do both: X.XScreenController)

i do that for a procedural generation system

it has stuff like WorldGen.Sources.Floats.LiteralFloatSource

[blissful stratus]

so i want to spawn a decal on partical hit the ground but how do i make the position as the hit position

[polar acorn]

https://docs.unity3d.com/ScriptReference/Object.Instantiate.html
Find one of the forms of the function that take a position as a parameter, and make sure to give it every parameter it needs

[blissful stratus]

ik how to do that but i meant how do i make get the position of collision hit

[frail hawk]

your Instantiate method is corrupted

[solar hill]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Collision.GetContacts.html

[blissful stratus]

ahh sorry i cant access the collision getcontact bec the func doesnt have collision it says gameobj

[polar acorn]

Then the best you can do is the object's position

[rough granite]

do you not have a ParticleCollisionEvent list defined in this code?https://docs.unity3d.com/6000.0/Documentation/ScriptReference/MonoBehaviour.OnParticleCollision.html

heck it shows how to get the collision position in the doc of OnParticleCollision

[mint imp]

So could I just make the script that holds that data
"DontDestroyOnLoad this"
It would persist but sounds strange to just have it lingering in the scene, and I would need to find it from whatever scripts needs that information.

Would there be a way to just make a custom serialized class for this?

[polar acorn]

That is what the Singleton Pattern exists to solve:
https://gamedevbeginner.com/singletons-in-unity-the-right-way/

You'd make a manager that always exists, modify the data in it through static reference, and make it persist between all scenes so the ones that need it can read from it

[foggy sparrow]

Hi, i dont know why but i cant go near any of my prefab now, when i go near any object they fadeout like i have a huge hitbox and make me unable to "aproche" them
Im sure it a small editor settings but i cant find it :0

[swift crag]

Hit F with a small object selected

The problem is that unity has your scene-view camera configured to show a very large object

It adjusts the near and far clipping planes (which limit how close/far an object can be and still render)

[foggy sparrow]

that worked thx!

the player will land on it and that array of prefabs will deactivate, they act as a barrier

[naive pawn]

consider sending your entire thought as a single message

sometimes the answer pops out just while typing it all out too

[midnight summit]

well true, let me rephrase it then:

I want to set a button that can activate/deactivate a set of prefabs, the player will land on it and that array of prefabs will deactivate, they act as a barrier that will block the way. The thing is, in the array, it only deactivates the last barrier of the array.

I have an interface that controls the button logic to Activate(), Deactivate() and Toggle(). So why is it the last Prefab of the array the only one deactivating?

//interface code
public interface IFloorButton
{
    void Activate();
    void Deactivate();
    void Toggle();
}

//Barrier State code
public class BarrierSetState : MonoBehaviour, IFloorButton {

    private Animator m_Animator;
    [SerializeField] public BoxCollider2D m_Collider;
    [SerializeField] private bool isActive;
    private void Awake()
    {
        m_Animator = GetComponent<Animator>();
        m_Collider = GetComponentInChildren<BoxCollider2D>();
    }

    public void Activate() {
        m_Animator.SetBool("isOpen", true);
        m_Collider.enabled = false;
    }

    public void Deactivate() {
        m_Animator.SetBool("isOpen", false);
        m_Collider.enabled = true;
    }
    public void Toggle()
    {
        isActive = !isActive;
        if (isActive) {
            Activate();
        }
        else {
            Deactivate();
        }
    }
}

//Button code
public class FloorButton : MonoBehaviour
{
    private Animator m_Animator;
    [SerializeField] private GameObject[] m_AttachedObjects;    

    private IFloorButton m_Button;

    private void Awake()
    {
        foreach (var ObjectInArray in m_AttachedObjects)
        {
            m_Button = ObjectInArray.GetComponent<IFloorButton>();
        }
        m_Animator = GetComponent<Animator>();
    }

    private void OnTriggerEnter2D(Collider2D collider)
    {
        if (collider.gameObject.tag == "Player" /*|| collider.gameObject.tag == "Dynamic Object"*/)
        {
            Debug.LogWarning("Collision! Activating...");
            m_Button.Activate();
            m_Animator.SetBool("isPressed", true);
        }
    }
}

[slender nymph]

foreach (var ObjectInArray in m_AttachedObjects)
{
    m_Button = ObjectInArray.GetComponent<IFloorButton>();
}

what do you think this code here does?

[midnight summit]

well... is supposed to set the interface to every gameobject in the array

clearly

it doesn't do that

[slender nymph]

how many objects do you think that m_Button variable can hold?
-# hint: it is declared as private IFloorButton m_Button;

[midnight summit]

well can interfaces be arrays???

[swift crag]

an interface is a type

[slender nymph]

the interface cannot, no. but the variable of that interface type could be instead, yes

[swift crag]

IFoo is a kind of thing. IFoo[] would be an array of those things.

[slender nymph]

honestly though, that interface could really just be a component where it maybe has some unity events instead of method declarations, and other objects subscribe to those events. then you could drag the component references in the inspector instead of gameobject references that you then get the component from

[midnight summit]

so it would be private IFloorButton[] m_Button or private IFloorButton m_Button[]

[slender nymph]

well the latter isn't valid syntax. perhaps review the beginner c# courses pinned in this channel if you struggle with understanding the basic syntax of the language

[midnight summit]

ok thanks

[languid pagoda]

bro are you on the spectrum or something? This isn't how normal people speak to each other.

You could have just left it at "well the latter isn't valid syntax. perhaps review the beginner c# courses pinned in this channel" anything past that was just being an asshole

[rough granite]

someone's feisty eh

[sour fulcrum]

hey dummy your on a game development server

half the people here are on the spectrum

[languid pagoda]

not really just think its a littel wild the same 6 people it in here and shit on new people

[naive pawn]

"100% of people are on the spectrum, it's a spectrum"

[sour fulcrum]

real shit

i think people can be a little harsh in wording sometimes but that one just wasn't at all

[rough granite]

it's not shitting on new people it's telling them to learn correct syntax before it's too late, if you went into the industry and started doing whatever with your code's syntax you're going to get bullied and judged

[languid pagoda]

nah what he said was needlessly harsh

[midnight summit]

dw, I don't mind, but thanks to look around

I'm a bit rusty on c#

haven't been programming on it for a good while

[sour fulcrum]

Genuinely homie I think your reading into it, It's not harsh at all

[naive pawn]

imo it couldve been worded more gently but the content is appropriate

[sour fulcrum]

basic syntax isn't like a slight, it is what that means

[slender nymph]

literally was just "if you're struggling go review". anyone reading any further into it is just looking for a fight

[naive pawn]

i mean, telling someone "you don't understand this yet" kinda necessarily has a degree of harshness to it

[midnight summit]

honestly the last thing I need is people being soft about it, better to tell me "hey you are wrong here" than just being possitive in a way

[rich adder]

this whole convo shouldve ended 12+ messages ago

[languid pagoda]

again he could have just left it "well the latter isn't valid syntax. perhaps review the beginner c# courses pinned in this channel" anything he said beyond that was just him being an asshole

[midnight summit]

if not, the toxic positivity mindset takes over and it gets everything worse

and I agree with nav

[naive pawn]

mentioning basic syntax as a thing to focus on is beneficial.

[sour fulcrum]

its just you homie

[languid pagoda]

nah yall are just chronically online or somet;hing

[rich adder]

its valid syntax, just not for C# . The suggestion as valid

[sour fulcrum]

i mean sure, again its a game dev server 😭

[languid pagoda]

someone would crashout on you if you said that to randoms in public

[rich adder]

you being atticus doesn't change how OP decided to take it..

[languid pagoda]

something tells me boxfiend gets punched in the mouth a lot

[sour fulcrum]

programming advice is a different context to talking to random people in public

[sour fulcrum]

are you okay

[rough granite]

in a discord server about making video games it kinda makes sense that we're online, you know cause it's not like video games can be made in the grass

[naive pawn]

i agree it was harsh. telling someone "you are wrong" is necessarily harsh.

it couldve been worded more gently. quite subjective as to how important that is to prioritize.

i disagree the part about basic syntax shouldve been left off. that's useful information to the learner about what to review.

[languid pagoda]

I am just gonna drop it but yall need to stop being assholes to the newbies smh

its daily in here i open this chat and see the same 6 people talking down to someone who has prolly been fucking around with the engine for 2 hours

[sour fulcrum]

maybe don't use being on the spectrum as an insult if you want people to take that advice seriously

[languid pagoda]

it wasn't an insult. The dude is either autistic or he was intentionally being an asshole. Again well adjusted mentally well individuals do not speak to people like taht

[sour fulcrum]

brother

[naive pawn]

so you're saying being autistic is unintentionally being an asshole, or...?

[slender nymph]

and consider that just because something is said bluntly that doesn't mean it is an attack. people helping in here volunteer to do so, they aren't required to waste time blowing smoke up everyone's ass and coddling them

[languid pagoda]

You typed more words just to be an asshole bro. Dont ping me.

[naive pawn]

those "more words" were useful info bro

[sour fulcrum]

i hope you feel better man

[midnight summit]

haha yeah

[mint imp]

I've been using singletons for a while now but i cant use those for each indiviual planet object that can be selected, only the manager that handles them.

I have 2-8 planet that can spawn at once, all with unique values.
When i select one i need to pass those values to the next scene but just dont know the best way to do that, im familar with scriptable objects but i create the values for those in the inspector, that wont work here where i need the values randomized. Is there anyway i can create a custom "Planet attributes" that holds all the values and can be stored into the next scene and read for the values.
Basically is there something like a scriptable objects that i can create in code at will and pass it around like a variable

[polar acorn]

Make a planet attributes class that holds your data, and make a list of them on your Singleton. Add a planet? Add to the list.

[cosmic sable]

currently in learn unity I think im stuck here

it gives me this error saying there is no definition for gameover

on my other code, I've already added getcomponent to connect the codes

[teal viper]

Please don't screenshot the status line... 😅
Open the console tab/window and either screenshot the error there or copy paste it.

And then also share code correctly. (upload the whole script/s to paste sites).

what the hell

now its working

[teal viper]

Likely didn't save the changes.

[cosmic sable]

I tried making a new function to add a debug log

it printed

then deleted it again then

added what I meant to added

[cosmic sable]

saved it like 4 times

thats weird

anw thanks for answering my question, glad it worked out somehow

https://pastes.dev/rAptKEqNQD (Target) https://pastes.dev/SueBKcytad (Game Manager)

Why does everytime I click to destroy the object somehow my unity freezes, and used up to 50gb of ram

I trie removing the particles and it worked

after I tried doing it again it freezed up again (without the particle)

nvm, camera issue, I tried switching to the game view without the dev view it worked out fine somehow

froze up again when I added the prticle

nvm I added while instead of if

I think im gonna sleep today geez

[lofty summit]

question, does anyone know why my shadow type on my light doesn't change it at all between shadow types? like i toggle between the soft and hard, but the light doesnt visually change.

Any help?

[winter monolith]

whats happening why is there a weird jitter blur thing going on whenever i move and move camera simotaniously

[teal viper]

Likely an issue in your movement or camera logic. To put it simply, there's a desync between rendering frame rate and your movement/rotation.

[topaz gorge]

If you share your camera code would love to help

[minor pier]

Heya y'all, this is probably a very basic question but how do i make it so the raycast is attached to the object instead of following it? i have mainly found people doing it this way but it kinda messes up my jump a lot where it stays stuck in the body and doesnt go back down which means no jumping..

        Debug.DrawRay(transform.position, groundcheck * 1f, Color.red);

        if (Physics.Raycast(transform.position, groundcheck, 1.1f, LayerMask.GetMask("Ground")))
        {
            IsGrounded = true;
        }
        else
        {
            IsGrounded = false;
        }```
Thought it'd be worth asking here cus like i said, i mainly saw people using a transform.position.

[undone rampart]

wdym by attaching it instead of following? Attaching implies following

[naive pawn]

it's pretty unclear what the issue you're experiencing is, could tou elaborate

[minor pier]

ah yeah sorry, basically what i mean is as if ur parenting it onto the object, same for if i would put the camera on the capsule as a first person camera, what its doing rn is following the transform by code, but its slow and follows behind with a small bit, what i want it to do is move as fast as the body itself, i might be able to record it if im still not making much sense

[undone rampart]

what is following? the ray cast?

[minor pier]

ya

[undone rampart]

where is this raycast called?

[minor pier]

fixed update

that might be the issue aint it..

[undone rampart]

what are you using for your character controller?

a rigidbody or a character controller

[minor pier]

rigidbody

[undone rampart]

then it should be fine

fixed update runs every physics tick which is the same as the rigidbody

i dont see the point of transform direction

you can just do -transform.up

[minor pier]

oh yeah bet

[undone rampart]

also you can simplify that logic to a property

public bool IsGrounded => Physics.Raycast(transform.position, -transform.up, 1.1f, LayerMask.GetMask("Ground"));

additionally I reccomend using a SphereCast instead of a ray cast, since the ray can give you false negatives when the character is hovering over an edge

[minor pier]

ohh yeah true

holdup lemme see if i can get that working :)

[naive pawn]

(false negatives)

[young condor]

Hey does this server allow asking for help when it comes to modding an existing game?

[minor pier]

        if (Physics.SphereCast(transform.position, 0.6f, -transform.up, out RaycastHit hit, 1.1f, LayerMask.GetMask("Ground")))
        {
            IsGrounded = true;
        }
        else
        {
            IsGrounded = false;
        }```
Came to this currently, idk if i did it correctly, i did add an OnDrawGizmos but the shape it draws isn't fully 100% correct on where its at, it still stops me from jumping quite a few times.

[burnt vapor]

Nope

[young condor]

Ok thanks for letting me know, anyone knows a server for that?

[nocturne crystal]

i wanted to ask about how unity's tileset system works

so i have been working on a top down game

and i know about unity 2D tile set

i wanted to ask wether it would be better to create a fallback custom system for map saving
or using unity's inbuild system would be better?

[naive pawn]

could you show the gizmo call and elaborate on how exactly it isn't correct? perhaps show screenshots

[minor pier]

    {
        Gizmos.color = Color.red;
        Gizmos.DrawSphere(transform.position - transform.up * 0.6f, 0.6f);
    }```
the issue is mainly that if i jump once or twice i cant jump for a solid bit, when i move normally the spherecast or raycast resets to its original position and allows me to jump again, and sometimes even then it doesnt...

[undone rampart]

looks like your sphere is not correctly setup

it exits the player's bounds

[minor pier]

oh..

[naive pawn]

spherecast is not just a sphere, it is a sphere moving along a direction for some distance

[minor pier]

ohhh

[naive pawn]

when i move normally the spherecast or raycast resets to its original position and
your cast is attached to the transform here. do you hvae multiple objects lagging behind each other or something?

[undone rampart]

I think a check sphere is more what you want

[minor pier]

not that im aware of, everything else moves with it straight away, i only got the camera parented and nothing else is attached in any way if its either by code or parented

[minor pier]

time to learn that i suppose! :D

[nocturne crystal]

if i wasnt able to phrase that correctly

in unity when placing the tiles for a top down game
there is the usual way of making a tileset using the game assets and painting the map using that

but what i wanted it type of a fallback system, for when it isnt able to find a type of asset it uses a default asset assigned to it in the given category

[naive pawn]

could you show how exactly it's lagging behind in a screen recording or something

[minor pier]

i could show with raycast, gizmo doesnt show it, holdup brb

here, its going quite alr for whatever reason now but i was spamming space bar so sometimes the raycast didnt come down for a solid sec, its been worse before recording tho

[naive pawn]

and how'd you draw that line?

physics visualizer or debug or gizmo?

[minor pier]

        Debug.DrawRay(transform.position, groundcheck * 1f, Color.red);

        if (Physics.Raycast(transform.position, groundcheck, 1.1f, LayerMask.GetMask("Ground")))
        {
            IsGrounded = true;
        }
        else
        {
            IsGrounded = false;
        }```

[naive pawn]

and what method was this in?

[minor pier]

fixedupdate

[naive pawn]

could just be the lag from that, perhaps

[minor pier]

! basically returned it back to the beginning to show the lagging behind, it does it both for spherecast and raycast

[radiant void]

<:error:1413114584763596884> Command not found

There's no command called basically.

[minor pier]

shh, didnt mean it as a command mate :)

[naive pawn]

if you put the debug call in Update, does it still lag behind

[minor pier]

lemme check

yep still lags behind

is it maybe easier if i just add a sphere as a child, turn off mesh renderer, add on collision enter & exit and just communicate that bool to the other script to allow me to jump n such?

[naive pawn]

that'd be one way to do a groundcheck yeah
it could be a trigger and then you wouldn't have to put it on a separate object really

that aside though.. this really seems like you have objects following each other, is this script on your player? and could you show the hierarchy of the player

[minor pier]

its with netcode btw, but i build the character controller before i added it so it shouldnt be that, the jump was already buggin beforehand, but thats why its a prefab basically :)

facing is just a small cube to show me where im facing for sanitys sake

[minor pier]

ok im testing the trigger in the hopes that that will do and save me from more raycasting & such 😭

[hearty ether]

hi
Im trying to make grid based building system and I need to change pivot point for my buildings
is there any easy way to do it ?
(sorry for my bad english)

[fickle plume]

Put in a game object container, or use any 3d software to change it, like ProBuilder or Blender.

[hearty ether]

Thank you

[cosmic quail]

easiest way: give them a parent gameobject and use that as a pivot

[river fern]

Is AI good in C# ?

[midnight tree]

||You shouldn't have written this... run||

[river fern]

Like if i want to correct something

[solar hill]

really only going to harm you in the long run for short term benefit

[river fern]

I dont understand 🙁

Like for exemple claude or geminie

[solar hill]

yes

the issue with AI is that its short term usefulness is not worth the long term effects it can have on a persons skill

its simply not worth using

especially not for beginners

[river fern]

O ok i see

Thx 🙂

[naive pawn]

for coding, it's a tool that requires a good understanding and solid experience of the environment you're working in to be effective. as a beginner, it's not going to help you learn, and you won't have the skill or knowledge to use it effectively.

[rough granite]

Correcting something with ai is the worst thing it can do

[sage mirage]

Hey, guys! I cant understand why the Unity doesn't throw an error when you are trying to pass vector2 to vector3

I mean syntactically its wrong and it will behave weirdly

[polar acorn]

Because Vector2 casts to Vector3

It just treats the Z as 0

[sage mirage]

I had a problem with animation only to realize that I have used Vector2 instead of Vector3 and I have stored on my moveInput Vector2 not Vector3

I mean I lost my entire day and Unity would have to throw a warning or an error at least

[polar acorn]

Casting Vector2s to Vector3s is a completely normal thing to do. MoveInput being on a Vector2 sounds completely standard, how are you inputting a Z-axis?

[naive pawn]

it's not syntactically wrong. if it were wrong it'd be semantically wrong or incorrect in types

[rough granite]

I like that unity has support to cast between these types so easily

[tranquil forge]

when i schedule a job does the job struct get copy on every worker thread for each execution or all of them able to access that one instance ?

[brave compass]

Must be copied, because writing to fields in the struct in one job execution doesn't affect others. Any writing must be done in native collections.

[tranquil forge]

dang guess i have to make it small, did you read this anywhere tho

[verbal dome]

Are you worried about the size of the struct in memory/memory bandwidth?

[tranquil forge]

just that i could do something a bit more work to avoid the memory and copy cost together, i have always thought it is shared fr

[verbal dome]

I'm just gonna say it's probably negligible compared to the overhead of starting the job/spinning up the threads

[tranquil forge]

yep probly but i could so imma do it anw fr fr

but any docs mention this?

[obtuse hollow]

How to ragebait part 1 lol

[obtuse hollow]

Yes it is okay if you are aware of many things regarding its usage. If you just rely on AI to do everything - it will fail, if you enchance your skill with AI or make it do repetitive work like generating a long simple code that needs to be written anyway - its a great tool.

[errant breach]

Being called "Norman" in front of a French is the best way to ragebait actually

||Because one of the biggest pred on the french Youtube also was called Norman :(||

[naive pawn]

that "if" is pulling a lot of weight. a beginner would not be aware and may not even know about what to be aware of

[winter monolith]

i changed it a little but now its even jittering weirder

i heard of cinemachine is that any good

[slender nymph]

https://unity.huh.how/mouse-input-and-deltatime

also yes, use cinemachine

[winter monolith]

i took off time.deltatime and itss till blurry i put on interpolate and the dynamic update thing and everything

am i just missing cinemachine now

[swift crag]

"dynamic update thing"?

[winter monolith]

for input system settings

moving horizontally is smooth now but camera rotations when moving is when it loooks weird

[drowsy tiger]

Does disabling domain reload not work with non serialized actions?

[swift crag]

"non serialized actions"?

i'm not sure what that means

[drowsy tiger]

err

(I know actions are not serialized, but I put it there to kinda force the point across just in case)

[swift crag]

if an object survives from one play session to the next, then those fields will retain their values

(I don't recognize the ClearOnReload attribute)

ah, maybe https://github.com/joshcamas/unity-domain-reload-helper

[drowsy tiger]

Yeah that

I plastered that too, to get it working

[swift crag]

what does "not work" mean?

[drowsy tiger]

Well, I'm pretty sure somehow they're retaining the values from the previous session

Maybe because they're originally stored on scriptable objects?

[sour fulcrum]

yeah thats how scriptableobjects work

[drowsy tiger]

But they're NON serialized data!!

lol

[swift crag]

This code only works for static data

[sour fulcrum]

still waking up, sorry aha

[swift crag]

so it's not going to do anything to OnStart or OnComplete, since these aren't static fields

[drowsy tiger]

Yeah I know. Those were just hail mary's

What's the "correct" way to clear scriptable object non serialized data on domain reload?

[sour fulcrum]

Someone might chime in with a stronger solution but i think if you have Awake and OnEnable both run a shared "init" function it should cover all the edge cases you need?

[winter monolith]

im trying to do this cinemachine thing i dont even know if im doing it right but its still there

[swift crag]

ScriptableObjects will stay alive from play session to play session, so this won't help

notably, changing scenes will unload assets that are no longer referenced

but if you just enter and exit play mode in a scene, any assets that the scene requires will stay loaded

[drowsy tiger]

:(

Okay, I'll just force reset them for now

[sour fulcrum]

I'm pretty sure one of those runs? ill double check

[drowsy tiger]

OnEnable should run

[swift crag]

They will run when the object gets loaded, but the object doesn't unload even when entering and exiting play mode

[grand snow]

never a good idea to keep runtime state in a scriptable object

There is some SOAP system that tries to fix this but believe me all it does is fuck up your data at stupid times 😐

[swift crag]

it's a lot like mutating any other asset, like a material

[drowsy tiger]

I was trying to store events in it

[swift crag]

one place I do store runtime data in my ScriptableObjects is for my settings system

each asset corresponds to a setting

on startup, i store a default value and then, usually, overwrite it after loading the settings file

therefore, it doesn't matter if the object stays alive; it gets reset by my settings system on next startup

[sour fulcrum]

Though like Material modification you can make runtime instances of scriptableobjects which is a way to do this kind of thing

[grand snow]

whatever subs should unsub on destroy/deconstruct (may cause infinite load)

[swift crag]

Right; i should say like mutating any other shared object

[swift crag]

I presume you're working with assets here.

e.g. you've created an asset out of the SO named "GameStartEvents"

and things in your scene reference this asset

[drowsy tiger]

Something like that. Its a bit more intertwined than just game start, as its for a Quest System

[swift crag]

right; this is just an example

the important thing is that you're using assets

[drowsy tiger]

Its easier for a designer to set it up with SOs

[grand snow]

A foolproof system that fixes this but keeps the ease of use would be an event bus that uses scriptable assets only for event ids/keys

[swift crag]

Why does this cause problems?

Do you wind up trying to execute delegates from the last play session?

[drowsy tiger]

Yeah. I cleaned them up for now, by resetting everything manually before subscribing

[swift crag]

I'm wondering why you're ever trying to call OnStart or OnComplete without ensuring that the object is configured correctly

ah, so it's less that you're trying to use it early

but the stale data from the last session still causes issues

[drowsy tiger]

I'm 100% sure its the stale data. I got the invocation list when I subscribe to it, and it was 2 for whatever reason. If I play after changing code, it works perfectly. If I play without changing code, it breaks

But nayway

Fixed it, I guess. Learnt something new

[drowsy tiger]

This is a good workaround. A bit painful to setup now, as its another system, but I'll keep it in mind

[grand snow]

by "break" did it just throw a unity destroyed/missing exception?

[drowsy tiger]

Nah, I got some logs that were a bit shady. Basically, I got multiple logs for the same objective ID on consecutive play sessions

[grand snow]

Event bus/signal systems can be hard to debug if overused so keep that in mind

[drowsy tiger]

They still don't error out presumably, because the other stuff reliant on this is kinda halfway there, and somewhat expectant to get called multiple times

[grand snow]

Then yea post play clean up was required to unsub/clear events

[swift crag]

If this is an editor-only issue, then my first thought is to just fetch all of the assets with AssetDatabase on startup and clean them up

[drowsy tiger]

And the assets its referencing is still other SO's so 😂

[swift crag]

As long as you only ever set up the delegates once, you will never have stale data in the built game

(since the game will...you know, close)

[drowsy tiger]

Well, that would be great. Assumes I actually make a build of this game again someday

[faint scroll]

please help me I don't understand why the color is displaying lighter than it should be

[rich adder]

this isn't a coding question

unless you're coloring those with script and you can show the script

[faint scroll]

https://gist.github.com/ParkourJohnson/3cbc666d68f6f88ad54e4a5daeed98cf

[teal viper]

I'd check the frame debugger first to make sure these sprites are really rendered with a bad color or perhaps something else is rendered on top.
If you can confirm it uses bad color there, I'd assume it has to do with the initialization timing.

Oh, I see you've been answered. Please avoid crossposting in the future.

[faint scroll]

okay, thanks for help

[wicked stratus]

sorry for deleting immediately after posting, I posted the wrong screenshots.
For some reason, OnEnable on a few scripts is being called before awake on a specific script. The GameObject with the script calling awake is active upon play. everywhere I am looking says awake should be calling before OnEnable, so I'm wondering if there are other common reasons why this may be the case?

I've tested with debug statements and the debug statements in OnEnable are appearing before the debug statements in awake, and it also gives a NullReferenceException error for something set in that awake that is being called in the OnEnable script.

[weak hemlock]

Hey, im fairly new to Unity, ive been watching a few tutorials and wanted to try making a dashing feature ontop of this 2D tutorial ive been watching.

It does "Work" the animations fire off, the player state is reset, gravity resets, im just confused as to why my player sometimes in the midst of their dash seems to stop or decide not to dash period (The animation still plays, but the distance they cover varies)

Im sorry if im leaving out important screenshots, I dont really ask in chats like this for help often if at all.

[wicked stratus]

upon some further research, I think script execution order is something I'm going to look into and try to adjust, and also add a few checks/possibly coroutines to handle if it's taking a little longer than normal

https://pastes.dev/QFVpNcA2JY

no idea if I did it right

guess I did

[wicked stratus]

I put debug statements in the OnEnable function and the Awake function, both were enabled when pressing play, and the debug statement from OnEnable printed first. It also had code that relied on variables set in the awake function that were giving nullexception errors. I honestly am still not sure why this was the case, but I have fixed it and will cross that bridge later.

[weak hemlock]

https://pastes.dev/v02UhQS3k5

[naive pawn]

could you show those? and make sure to put in a context to make sure you're looking at corresponding logs, and that collapse in console is disabled

[wicked stratus]

sure, give me a moment to recreate it

it is something I will need to have an actual fix for in the near future so I appreciate the help. i can comment out the offending code for now though.

[naive pawn]

where are animation events for EnableMovementAndJump, EnableDash, DisableIsDashing, set (eg which animation clip)?

they seem to have quite overlapping control, so they might just kinda be stepping on each other

[weak hemlock]

They are set on the animation timelines, disabled at the start of the animation, enabled at the end

[naive pawn]

right, but which animations

[weak hemlock]

playerMove has the EnableMovementAndJum

playerDash has the EnableDash, DisabledDash

I likely misunderstood what your asking

[naive pawn]

so it seems like perhaps DisableMovementAndJump is resetting the dash

[wicked stratus]

hm, I'm having trouble recreating it. there are still heaps of other errors going on when I uncomment the particular offending code but it's something I feel like I won't have too much trouble fixing. For now I'm content with tabling it, but if I see this behavior again while trying to fix the other errors I'll come back. I think some of my fiddling must've fixed it.

[naive pawn]

so basically this - i think you should at least have each method have a separate role, also isDashing and canDash seem to overlap quite a bit as well (unless there's some cooldown?)

[naive pawn]

if playerMove is the looping animation for moving it probably shouldn't have these animation events though

[weak hemlock]

Fuck sorry my bad... its not playerMove

playerAttack has those

my heads, sideways

[naive pawn]

gotcha

that makes more sense

in that case you could probably do away with all the canMove/etc and then set just isAttacking/isDashing and go based on those

[weak hemlock]

probably, thankyou regardless.

[dull slate]

I'm having trouble getting player movement/player controller scripts to really click for me. It seems like there's so many ways to write them using the new and old input system. Is there a sort of right way to always do it? Like specific rules to follow?

[dreamy wraith]

i can send you the old script if youd like and you can copy and paste it?

[rich adder]

nope

[winter monolith]

why isnt this timer working i feel like it should be working

[rich adder]

assumptions don't get you far well, you need to debug

[dull slate]

Yes please, think I'm overthinking it all super hard

[winter monolith]

well it actually does work only when playmode starts

it doesnt happen again

[rich adder]

what will that learn...

[dreamy wraith]

they can se if they understand itt

ill send a ss so they have to type it still 😄

[rich adder]

copy and pasting something is the same as blindly copying..

[dreamy wraith]

alr no copy and paste thenn

[dull slate]

I can type it out and write comments to see if I understand what's going on maybe?

without executing it

[dreamy wraith]

yep smart

[naive pawn]

you're computing jumptimer and jumptime at the same time, jumptimer >= jumptime is just Time.time + 0.1f * Time.deltaTime > 1f which is almost always true

[winter monolith]

so the jumptimer = 0f doesnt just set it back to 0?

[naive pawn]

jumptimer is a local variable, so it's setting that one to 0. the next time you call jumping(), it gets a new jumptimer variable, which starts back at Time.time + 0.1f * Time.deltaTime

[winter monolith]

interesting

this fixed it

thanks

Hello ! Im trying to give my camera to "Target", but it doesn't work wich is normal.
What can i do so that i can give a prefab the camera ? Thank you ! I tried "target = GetComponent<CameraShaking>();" which doesnt work-

[sour fulcrum]

is there a camerashaking component on that object that code is running on

[keen dew]

If the CameraShaking component is on the main camera it's a special case and you can do target = Camera.main.GetComponent<CameraShaking>();

otherwise put the reference on the component that instantiates this prefab and pass it on

[polar acorn]

Which CameraShaking object do you want it to reference?

[rare condor]

I'm getting this warning, why does it want this property as serializable? I don't really want it to unless necessary. It's not a data holder in a sense, that's separately. It has some runtime data.
Is it because it's public and shown in editor properties?

[errant breach]

Oh wow sorry, thanks IAmBatny, Nitku & digiholic for trying to help, but a friend already did and i forgot to delete my message, sorry for that and thanks again ! :D

[ivory bobcat]

Is the type Serializable?

[polar acorn]

If you want this to be editable in the inspector, your Sudoku class needs to be serializable. If you don't need it to be editable in the inspector or saved to disk, you can probably ignore the warning

[rare condor]

Sudoku class is not currently, error goes away if i make it

I don't need it editable

[slender nymph]

If it doesn't need to be serialized you can mark the variable as NonSerialized

[ivory bobcat]

Well, that's what the error is telling you. You're attempting to make it serializable with the public modifier but that would be impossible as the class isn't serialized. Thus a warning is simply given.

[rare condor]

ok this makes warning away:
[NonSerialized]
public Sudoku sudoku;

[polar acorn]

Yep, that'd do it. Basically, you got one thing saying "Serialize this" and another one saying "Don't serialize this" and the compiler was just trying to guess which end of the problem was the mistake. Generally, people want variables exposed to the inspector, so it is probably designed to give that warning first

[rare condor]

Just switched to Unity 6.6 alpha and it's giving more code guides than before, good thing i think

But also some things are becoming deprecated and i'll need to workaround

BinaryFormatter...

[keen dew]

tbf BinaryFormatter has been obsolete for at least 6 years

[swift crag]

at least it's not as catastrophically bad as, say, python's pickle

which will literally just run arbitrary code

[keen dew]

That's what it does though

That's literally the problem, it serializes methods so you can inject whatever code you want

[rare condor]

I was just using binary format because i like highscore table not easily editable. I suppose i should use some compression or format method instead then

[swift crag]

oh yeah, if you want to discourage trivial editing, just serialize to json and encrypt it or something

it's obviously bypassable, but it'll make it slightly more annoying

[teal viper]

You can still write binary files. Binary formatter is not the only way.

[swift crag]

yes, BinaryFormatter just happens to be one way to do so

[rare condor]

and it's supposedly super fast compared to string manipulation of JSON

[swift crag]

it's still a bit more involved than literally just saying "run this code!", but yeah, it's pretty bad

https://googleprojectzero.blogspot.com/2017/04/

In an ideal world we’d find that one serializable class which just executes arbitrary code for us. Sadly (as far as I know of) no such class exists. So instead we’ll need to find a series of “Gadget” classes which when chained together perform the desired effect.

gadget-chaining is a fun topic

oh, lol, but then they explain that ObjectSurrogate lets you do this as long as you can find something that runs an arbitrary delegate

[night raptor]

I doubt binary formatter is "super fast", writing to a binary file sure is usually faster than JSON but for you writing a score or whatever game state it won't make any difference. Even so, didn't binary formatter write a TEXT file with 0s and 1s in it? I might remember totally wrong but from my recollection, binary formatter didn't produce a binary file but a text file which is really silly to begin with

[rare condor]

No it was really binary, scrambled bytes of 0..255 char code

[night raptor]

aight, I stand corrected then. If this article is to be believed, it wasn't any fast though (much slower than JSON): https://medium.com/@maximn/serialization-performance-comparison-xml-binary-json-p-ad737545d227. I know it's old as ever, I intentionally searched for old stuff because all I can find now is info of the safety issues and deprecation

[night raptor]

All the other performance comparisons I can find seem to indicate the same, at best comparable performance to JSON and XML serializers and definitely slower than other binary serializers like Protobuf. Fastest of all would probably be your own binary writer but that you probably shouldn't worry abou the performance unless you are saving a ton of data.

My best guess would be that it might rely heavily on reflection but I never looked into how it works since it has been known for a long time that it is insecure

[rare condor]

Well, i know many games go the lazy way with data, at least including Civ V and so on with astonishingly slow turn change processing. You can only suspect they spend majority of time comparing strings

[night raptor]

Very possible, but again, you would need to save a ton of data for it to matter. Especially if you only need to save at the start and end of the sessions, it wouldn't really matter whether it takes 1ms or 10ms would it?

[rare condor]

no that's nothing, it's when it's 10000ms i twitch badly

[night raptor]

Never played the game but AI overview seems to suggest the lag in question would be caused by AI navigation and such rather than any saving or loading. Believe me, you can serialize and deserialize a huge amount of JSON data before it takes 10 seconds. Unless you have gigabytes of data to store, you can use JSON without having to worry about anything with such generous budget of 10 sec 😅

[rare condor]

well, that's not what really troubles me, it's that my json file now contains nothing but this:
{}

I debugged there are 12 tables that should be in it

[night raptor]

Where's the trouble though?

[rare condor]

string s = JsonUtility.ToJson(highScores, false);
Debug.Log(highScores.Length);
File.WriteAllText(highScorePath, s);

[night raptor]

Would you mind sharing the whole script? It would be really useful to see what type highScores is etc.

[rare condor]

public static HighScore[] highScores;
...
[Serializable]
public class HighScore {
public string[] name = new string[MainScript.NumHighscores];
public float[] number = new float[MainScript.NumHighscores];

public HighScore() {
    for (int i = 0; i<number.Length; i++) {
        this.name[i] = "-";
        this.number[i] = -1f;
    }
}

}
... there's some sub classes too

i get no hints or warnings about the codes

it saved perfectly when i still used the binary saving

only difference is json now

[night raptor]

I haven't used JsonUtility for a long long time but I would bet it has something to do with highScores being static, unity doesn't serialize static members and JsonUtility follows the unity serialization rules

[rich adder]

you're right

static is a no go

[rare condor]

will change

[rich adder]

BinaryFormatter or whatever else in System is not Unity so it doesnt follow Unity serialization rules

JSON.NET would do the same as the System one and serialize it..

but also do they really need to be static ?

i would do

[Serializable]
public class SaveData{
    public HighScore[] highScores;
}```

[night raptor]

Unrelated to this problem but I find this code little odd. I assume you are saving high scores for multiple levels or something like that. The class HighScore by its name sounds like it saves one entry but seems to be saving a whole leaderboard (which in my opinion would be a better name for the class)

[rare condor]

It's working like that, a container class that includes the table in it, + it's no longer static

//public static GameConfig config = new GameConfig();
public static GameConfig config = new();
Is this really the recommended way now?

[rich adder]

its not the recommended way maybe i'd say *preferred , its just an additional option when the type is already obvious, there is no reason to write it twice

both are perfectly valid, the former will give you backwards compatibility with older C# versions / Unity versions if you care about that

[foggy sparrow]

Hi, im trying to make a drop system for my inventory inside a 3D game. I have a prefab made for generic item type with some script to handle picking up and some thing stuff.

How do i go about generating the prefab inside my scenes when i want to "drop" an item to the ground. i found out about the Instantiate() function but i don't really see how i can initialize some value to my newly created game object.

If anyone can link me a good article or just a page in the docs to learn how to do that that could be awsome thx ^^

(i have bhen at it since 2hours on and off but i cant wrap my head around it)

[naive pawn]

Instantiate returns the newly created object. you should typically not use GameObject with it, instead use the type of the component you care about for the prefab and then you'll get that component from the Instantiate call

[foggy sparrow]

thx

[urban cargo]

Modder here. Is there a way to get all of the resources at runtime? I'm trying to get data from objects that are only loaded from prefabs at runtime.

[solar hill]

we cannot help with modding unfortunately

[urban cargo]

That's fine. but it is a valid runtime Unity question.

[naive pawn]

https://docs.unity3d.com/ScriptReference/Resources.FindObjectsOfTypeAll.html?

[urban cargo]

I was using that. I expected <Object> to return the MonoBehaviours and the GameObjects using that. I'm probably just doing something wrong. Doing more testing.

Thank you for the response.

[wintry quarry]

Make sure you did UnityEngine.Object and not System.Object

[urban cargo]

Luckily VS caught that for me.

[urban cargo]

Yeah, I was definitely doing something wrong. I was able to match up a MonoBehavior to a UnityEngine.Object when using FindObjectsOfTypeAll.

Breh I’m having trouble with player movement can someone help

Cinemachine and new input system

It’s like the player moves on global space not local

[slim stag]

So I’m wondering like, does scripting just get to a point where you know how to do almost everything you want to do off the top of your head or do even the experts constantly reference other material to know what they want to do the code they write?

Sorry, wasn’t sure if this is a question for beginner or general.

[teal viper]

Yes, you will always need to reference something or do many trial and error iterations. Or both.
But it also depends on the task. Some things will become easier .

[slim stag]

I ask because I’m still in the very early stages of thing to watch tutorials to learn and I’m just like… okay but how am I supposed to really take this and go off on my own eventually. It’s just so very confusing, especially when I try and look up what each thing they’re explaining in Unity Doc but then Unity Doc just comes off like gibberish.

Recently learned that Unity Learn has a beginner scripting course so hopefully that’ll help.

[teal viper]

If everything comes off as gibberish, you're probably missing some prerequisite knowledge/understanding/"basics". Try to break it down to the smallest components possible and then learn about them. Or go over structured learning materials, like unity learn courses/ pathways.

[swift crag]

there's always something I'm referencing closely

ideally, i figure it out and start implementing it on my own later on

[slim stag]

Okay, thanks. If you don’t mind me asking, how did you start learning in the very beginning?

[teal viper]

Read through the manual at my free time.

Then trying to implement my own "dream project".

[slim stag]

Referencing like… a tutorial? Unity Doc? Or what?

[slim stag]

Sorry to sound dumb but what manual exactly? Like Unity Doc? C#?

[still ingot]

Hi how do I make a ray cast that is oriented with the player model? Every time I set the forward direction of the ray cast it is always facing forward and not rotating with the player object?

 [Header("Ledge Check")]
 public Transform ledgeCheckerStart;
 public float checkDistance;
 public LayerMask whatIsLedge;
 bool isLedge;

 private void OnDrawGizmos()
 {
     Gizmos.DrawRay(ledgeCheckerStart.position, ledgeCheckerStart.forward * checkDistance);
 }

 private void FixedUpdate()
 {
     isLedge = Physics.Raycast(ledgeCheckerStart.position, ledgeCheckerStart.forward, checkDistance, whatIsLedge);
 }

[swift crag]

sounds like this "ledgeCheckerStart" object is not rotating with the player!

Transform.forward is the world-space forward direction for a Transform, so that is the appropriate thing to use

[teal viper]

Unity manual and official C# docs.

[swift crag]

(wrong reply)

I can't really remember how I started in Unity

[slim stag]

Okay thanks. You’ve been of great help.

[slim stag]

Okay, thanks nonetheless.

[swift crag]

I have a strong programming background, so I think I just poked at docs pages and clicked on things. I've always been able to find my around new software pretty quickly.

Reading the manual is great; it will quickly introduce you to important concepts

e.g. "what is a GameObject"?

you don't need to read it cover to cover, of course

[slim stag]

Right.

It’s just… not that I expect to learn everything overnight, I just feel likely I’m hardly getting any grasp of this scripting thing like at all but imma keep at it.

[still ingot]

isLedge = Physics.Raycast(ledgeCheckerStart.position, this.transform.forward, checkDistance, whatIsLedge);

[still ingot]

Im still not getting it to rotate

[swift crag]

did you also update the Debug.DrawRay line?

[still ingot]

yeah this is what I currently have:

    private void OnDrawGizmos()
    {
        Gizmos.DrawRay(ledgeCheckerStart.position, this.transform.forward * checkDistance);
    }

[swift crag]

okay, then whatever this is isn't an object that is rotating

[still ingot]

This is code from the PlayerLedge script

[swift crag]

right, and the Player object is not rotating!

its rotation angles are all zero, and since it has no parent, it has no world rotation at all

(if it had a parent, its parent could be rotated)

Switch your scene view to Local, not Global, and then switch to translation by hitting W

This will show arrows for the selected object

red/green/blue are right/up/forward

[still ingot]

Okay I see now!

[rich adder]

I mean technically you can, especially with this ai slop practically feeding you answers

[sonic egret]

well that seems complicated solutions, was wondering if there were other solutions
I tried adding a circleCollider2D on my player so it would have foot and not climb walls, but it was not so convenient and it also messed with my collisions

[rich adder]

using colliders was the reason its too simple to work well

[sonic egret]

well I'd rather not use AI to be honest, being given spaghetti code to use without thinking isnt the way I will learn imo

[rich adder]

hence the "complicated" solutions, you have to start getting more complex if you plan on advancing

everything looks complex at first glance, its not that bad

will dig into raycast then

Hello, guys! I dont know if this question is related with Unity but there is a concept in Programming called Single-Threading and Multi-Threading that we were discussing in class yesterday and a teacher told me that Unity handles everything on a single thread instead of multiple threads. What does this mean and what is the difference between them?

[naive pawn]

What does this mean
that unity is primarily single-threaded, at least for the part that you care about. multi-threading is supported with jobs/burst, that kind of stuff, iirc.
what is the difference between them
with separate threads you can have things in parallel, rather than just concurrent (at the level you're working at. in the cpu they may still be concurrent). you can look up "parallel vs concurrent" to see some diagrams explaining the difference

stuff like Update timers or coroutines are concurrent, for example.

[keen dew]

Didn't you just say that you attended a class yesterday discussing them and their difference?

[sage mirage]

Yes I mean we didn't talk in depth about it

it will be next week lecture

we just did a small introduction

[sour fulcrum]

imagine doing stuff irl with one arm/hand, thats what Unity mostly does

if you have two arms/hands you could do two things at once

[sage mirage]

Haha that makes a lot of sense. Very good example. Ty!

[sour fulcrum]

The big kinda thing with Unity is most modern cpus have a fuckton of cores and thread (hands) but Unity isn’t built to use all of them

but ofc how fast you can do stuff with a single hand changes how much that may or may not matter

Learn by doing. You'll come accross plenty of challenges naturally and still be working on something you like, don't bother just doing exercises for the sake of learning.

[cosmic sable]

👍 so brute force coding, got it

[sage mirage]

Courses are very useful for foundation knowledge but after you get some experience you wont be needing them

[hard fossil]

Not brute force, learn by doing. Don't write the code if you don't understand it.

[sage mirage]

Personally, I dont need courses to learn something I just follow project-based learning approach

Just learn stuff you will need for your project you are developing

do not try to learn everything at once

[rough granite]

i've yet to look at unity's learn site for more than 15 minutes, and youtube videos kinda just suck

[cosmic sable]

very interesting advices, I will take note

[hard fossil]

Sebastian Lague's youtube videos are fantastic, but they're more for the advanced side.

[sage mirage]

No I dont mean you dont have to watch tutorials

haha

[rough granite]

to re say what they've said, while you may have spent the last few hours learning a bunch of stuff at once it'll take you another few days to break down what you've learnt into manageable and rememberable information that you can reuse

[rough granite]

no i know i was adding my own experience cause you had, where you said "personally" i had meant the same just left it out

[cosmic sable]

thanks for the advice guys. ill go sleep now

[rough granite]

i need this advice 😭

[cosmic sable]

I was pressured, but after hearing u guys Im calm now

[sage mirage]

I mean all beginners do watch tutorials but they are trapped in tutorials hell thats the main problem here when you are a beginner you dont know and you think that just by watching tutorials you will become a professional programmer. Our art is practical and without hands on experience you wont learn.

[hard fossil]

Also, most of the tutorials I've seen on Youtube, like Brackeys, teach bad coding practices.

[sage mirage]

Do they teach Game Programming Patterns?

I have seen many vids about DP

[hard fossil]

DP?

[rough granite]

oh yeah few years back now i really wanted to try and get into game dev and i went through ai to do so "made" a few projects that turned out awful and felt like crap. ended up with me not touching unity (or any other engine) for about 3 years .When i took a proper course in school on programming and decided to get back into game dev and i can certainly say since going to school for programming i haven't needed a tutorial like i did before hand.

[sage mirage]

Design Patterns

[hard fossil]

Oh yeah, actually AI, like ChatGPT is a fantastic tool for debugging or understanding code better. You can copy and paste and ask what's going wrong, or an explaination for how things are working on code you may not understand fully as a beginner, and can get deeper insight.

[rough granite]

there was a channel the sort blew up about a year or 2 ago now that also had some drama cause they used their videos to sell courses think the name was blackthornprod or smth. they did a lot of x game devs make a game.

[hard fossil]

Brackeys is mainly tutorials on features, so it's more Unity focused, rather than C# (in general), so they kind of just teach code that works, but isn't good standards.

[sage mirage]

Basically AI isn't a fantastic tool for beginners.

[hard fossil]

It is.

[sage mirage]

As a beginner you dont know how to code and it can be misleading

You have to know how to code to be able to interact with AI properly otherwise you just waste your time.

[hard fossil]

Anything can be misleading, but as an aide to coding, you'll understand more having it than not.

[rough granite]

it certainly isnt with a beginner you've no idea what it's writing or what it's even suggesting, you end up doing things that could be bad practice poor implementation or just outright incorrect without ever getting the chance to understand why

[hard fossil]

I'm talking about not for generating code, as I've said in my comment, but from getting more insight into bugs, and how your code is working.

[rough granite]

no when people use ai they are looking for quick fixes not using it to understand something fully. so using it to any form leads to a result that is outright worse than not at all

[ivory bobcat]

I recall there being a dedicated channel for this type of discussion..

[sonic egret]

I'd argue that some practice can be useful but with AI as a complementary tool
I remember using it in python saying "what is this function" so it would explain something specific for me
Really useful to learn and comprehend, tho it shall not be used to generate code

[rough granite]

ai's biggest down fall is debugging, if it's something simple like an error code a quick google search can give half the answers and the other half should be a red ~~~~ line from your ide and anything bigger like bad results (image example) ai cant work it's way through and ends up writing shit for you

[hard fossil]

AI is just searching a database of all the code it stole from GitHub, to simplify. So to just disregard it as a tool is unwise. It is powerful if used correctly, and not overrellied on, as well as understanding, it is trained on data from humans, and just like humans, it will tell you incorrect things sometimes. More often than not for simple code for beginners (e.g. solved problems, not so novel) it will be able to explain deeply or answer deeply questions you have about code you wrote. I don't suggest using AI in your IDE but copy/pasting into ChatGPT can help you question your code.

[naive pawn]

it's definitely a tool you need experience for to use correctly. a beginner would not have said experience

[sonic egret]

indeed

[naive pawn]

also, yknow... it's been trained on the stackoverflow questions too

[sonic egret]

and as useful as it can be, overall the less you use is the better, both from a learning point of vue and a ethics point of vue

[sonic egret]

got tired of stackoverflow after realize half of the answers were either condescendant or something like "erm I found the answer on google in 30 sec 🤓 " tbh

[hard fossil]

The ethical and legal implications of LLM's is another bag of worms.

[sonic egret]

sure, but it is to be taken in account imo
thats why I try my best not to use AI

but yeah its a whole other debate

[hard fossil]

I really don't think a beginner programmer has any relation to how to use an LLM. At the end of the day you can just ask it to explain something in analogies etc. It is a language model, so anyone that understands human language should be able to get useful information from it, regardless of skills in any particular area.

[hard fossil]

I would tend to agree with you here, although we pick our battles, so often what's useful wins. I've made a big effort not to have big tech in my life, but at the end of the day, I'm making a game, and I want to reach a wide audience, so Google Play is part of that.

[sonic egret]

yeah I get what you mean, there's things we can not or very hardly avoid and it is how it is
but as for AI it still is avoidable so yeah its at least that

[naive pawn]

ime it definitely does. LLMs can frequently be subtly wrong, a beginner would not be able to tell
LLMs are a tool for volume

[hard fossil]

That's true. But if we're talking about whether LLM's are useful or not, I don't think that's really debatable. ChatGPT I do use, but shouldn't if I'm fully aligning with my morals, but their are other alternatives, like Proton's Lumo, that fully encrypts and doesn't collect data. These LLM's are going in a better direction I think.

[naive pawn]

they are not useful for learning, and that's what's important for a beginner

[hard fossil]

Ok, sure we'll agree to disagree.

[sonic egret]

ofc they are definitively useful but at what cost
like generative AI in general have a human and environmental cost so terrible
and that without even mentionning that economic bubble and the RAM shortage
I think it goes much further than data collection and I find it quite terrifying

[hard fossil]

Completely agree with you in terms of how companies are using the technology. The technology itself though, is very powerful.

[naive pawn]

it is, but it's incredibly easy to misuse without experience

[hard fossil]

This is a skill in itself though. Not understanding how to use an LLM isn't the same as not understanding how to code, they are very different skillsets.

[naive pawn]

both are required

[sonic egret]

also I think that its hard to blame people for using it, its a very convenient tool and it has a lot of great usage so its understandable

[hard fossil]

They aren't. By that logic, LLM's wouldn't be able to answer questions. Learning is the asking of questions and getting answers.

[naive pawn]

LLMs were not built for truth, my logic leads to that conclusion, yes

[sonic egret]

maybe too powerful
like seeing expert in AI security quit their job and tell people we're doomed, while OpenAI CEO is like "AI is gonna destroy us but we'll have one hell of a ride in the mean time!"
damn

[sage mirage]

@hard fossil how much experience do you have in the industry?

both programming and game dev?

I was told to null check unity objects like SO's I don't need to use != null and can instead just bool check(?) it like this, but my IDE/the nullable package does not really like this
is there a way other than adding != null or doing moonInfo.RouteNode!.itemCost to suppress the warning more naturally?

[naive pawn]

converting to bool for objects is defined the same as what != null does

i think i recall the nullable package not playing super well with unity types because of unity's fake null, but i'll have to recheck that

what's the warning you're getting?

[ionic flax]

just the one you'd expect i think

[naive pawn]

i would not expect anything in particular because i have not used nullable lol

[ionic flax]

oh fair lol

it's pretty neat, but can be annoying with unity objects since I like to not include the != null part (partly because rider also yells at me for that iirc)

[naive pawn]

that warning on rider is kinda over-eager tbh

it's not technically wrong but it usually doesn't matter, some things you just have to do

i would guess that the bool check doesn't "inform" the nullable static analysis that it's been checked

[ionic flax]

yeah :/ was wondering if there was a way for it to but might not be

[pseudo hull]

Hey, does anyone know why my camera sometimes behaves weirdly as in teleporting to "random angles" in my first person 3d game?

Playercam.cs

using UnityEngine;

public class PlayerCam : MonoBehaviour
{
    public float sensX;
    public float sensY;

    public Transform orientation;

    float xRotation;
    float yRotation;

    private void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }

    private void LateUpdate()
    {
        // get mouse input
        float mouseX = Input.GetAxisRaw("Mouse X") * Time.deltaTime * sensX;
        float mouseY = Input.GetAxisRaw("Mouse Y") * Time.deltaTime * sensY;

        yRotation += mouseX;

        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -90f, 90f);

        transform.localRotation = Quaternion.Euler(xRotation, yRotation, 0);

        if (orientation != null)
        {
            orientation.rotation = Quaternion.Euler(0, yRotation, 0);
        }
    }
}

[naive pawn]

don't multiply mouse input by deltaTime (you will have to reduce the sensitivity to compensate)

[pseudo hull]

im so stupid tysm

[keen acorn]

Hiya guys, I've been trying to code a wheelofnames style roulette wheel on unity. Right now, the wheel just chooses a random z for the rotation, and lerps to it. Obviously not the right choice, it rotates forwards and backwards, and at different speeds. But I also tried giving it a RigidBody and setting its angularVelocity, which seems fine, but I don't know how random it really is. Besides, I'd like to be able to set the result via code in some way. How should I go about implementing the wheel?

Here's the current script i've got

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

public class RotatingWheel : MonoBehaviour
{
    public int outcomes;
    public float rotational_force;

    float target_z;

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            target_z = Random.Range(0, 360);

            int result = calculate_result(target_z, outcomes);
            Debug.Log($"Target: {target_z}, result {result}");
        }

        Quaternion target_rotation = Quaternion.Euler(transform.rotation.x, transform.rotation.y, target_z);
        transform.rotation = Quaternion.Lerp(transform.rotation, target_rotation, rotational_force * Time.deltaTime);
    }

    int calculate_result(float rotation, int outcomes)
    {
        rotation = rotation % 360;
        int result = outcomes + 1;
        while (rotation > 0)
        {
            rotation -= 360f / outcomes;
            result--;
        }
        return result;
    }
}

[keen dew]

Don't read the rotation from the transform, store it at the start and use that instead.

Vector3 currentRotation;

void Update()
{
    if (Input.GetKeyDown(KeyCode.Space))
    {
        currentRotation = transform.eulerAngles;
        target_z = Random.Range(0, 360) + currentRotation.z;

        int result = calculate_result(target_z, outcomes);
        Debug.Log($"Target: {target_z}, result {result}");
    }

    currentRotation.z = Mathf.Lerp(currentRotation.z, target_z, rotational_force * Time.deltaTime);
    transform.eulerAngles = currentRotation;
}

[naive pawn]

you could set a target as something in the range of like, 720 to 3600, and then you can smooth a value up to that value, then only set it the rotation to the transform

[keen dew]

The "wrong lerp" isn't great but that should fix the immediate problem

[naive pawn]

you should not read back transform.rotation components

especially not like that, since transform.rotation is a quaternion lol

[hard fossil]

Your comment is a bit misleading. Whether LLM's tell truth or lies really has nothing to do with anything other than what dataset it's been fed. At the end of the day, it's transforming the data set and spitting it out.

[hard fossil]

I have more experience in indie development than as an employee. Why? What about yourself?

[naive pawn]

i know how LLMs work, thanks.

[night raptor]

You are not, it is very common mistakes which a lot of tutorial makers have made as well making it very common among beginners. DeltaTime is often required but mouse input just happen to be an exception as it is already the delta of the mouse movement (how much it moved since the last frame)

[rare condor]

LLM's are amazing, you just need to push them for answer a little bit and not trust the first thing it spills out. Doubt its discovery etc, it will more often than not end up giving something really useful

I have a 20b gpt model installed on desktop PC offline, and yesterday gave it some long sequence of base-64 encoded string. It just happily analyzed its json format out. Did not take more than a minute

[cosmic dagger]

This can be true, but to only those who understand code and what they're asking

For beginner's, they take everything as truth, and don't know how to properly "push" for the answer, hence the problem . . .

[pseudo hull]

Btw, does anyone know why the version control doesnt seem to detect scenery component changes, as i just changed a value and it still tells me im up to date

[naive pawn]

make sure you've saved

[pseudo hull]

yea it seems to now have sent the scenery but only the changed part. for some reason on his end the components are not set correctly though, is there anyway i can send the entire scenery and have him force pull it

[hard fossil]

So beginners in any field of knowledge take everything as truth? Therefore they shouldn't ask questions because they might believe the wrong answers? This is a very strange take. It also would apply then if they ask someone a question, and someone tells them something incorrect. So in effect, asking questions would be pointless.

[naive pawn]

LLMs are perceived as a source of truth to beginners yes

[naive pawn]

are you referring to scenes? merging individual changes is kinda how vcs works

[hard fossil]

Ok, so a source of information that is often correct shouldn't be used because your view is that a lot of people perceive it to be true, so therefore when it's wrong they won't accept it as wrong?

[pseudo hull]

yeah but for some reason the scenery doesnt seem to carry over correctly, i just modified a number in the components of my player and uploaded the scenery, after he pulled it though nothing changed for him

[naive pawn]

LLM usage is private. when a beginner gets a wrong answer, they may not have enough experience to see any part that may be inaccurate.
in sources like wikis, any user who knows something is wrong can fix it. in youtube tutorials, mistakes can be pointed out in the comments. in docs, PRs are made to fix inaccurate content. in community forums or servers, other helpers can challenge the incorrect answer. this is what makes them more reliable.

inaccurate base assumptions cause a lot of pain as you get into more complex stuff, and honestly it is an incredible pain for us as helpers

very few people, and even fewer beginners will share their entire thought process that would reveal the incorrect assumption. it wastes months of time just to learn something basic.

[hard fossil]

I can't really argue with something like, oh but someone out there might misuse it, so therefore it bad. So I'll leave it at that. They have their strengths and weaknesses just like any other way of getting information.

[naive pawn]

95% of the usage from beginners ive seen here, in other servers, in real life, have been misuses.

[hard fossil]

It seems like you don't really have any argument against LLM's, only what you think people's perceptions of them is.

[naive pawn]

just hedging my bets there, i don't recall any proper usage of them to actually learn

my arguments have been against.. beginners using LLMs, not against LLMs as a concept.

[hard fossil]

To be more specific, your arguments are only against LLM's being misused. My argument is that LLM's are a good teaching aid. Every teaching aid in the world can be a bad teaching aid, if it's misused or taken as gospel, that is obvious.

[naive pawn]

wow another strawman

LLMs aren't even a teaching aid to begin with

[pseudo hull]

nvm restart worked btw

[hard fossil]

I'm not sure you understand what a strawman argument is. I didn't make one. I didn't assume your position and argue against it.
LLM's have been a teaching aid for me, so to say they cannot aid in teaching something is just plain wrong.

[somber lantern]

why does this happen, can someone please explain?

[naive pawn]

you've made several assumptions about my position lmao. i'm not interested in discussing this

[hard fossil]

Okie dokie

[dry pulsar]

Anyone has a hint?

[hard fossil]

Create a cooldown variable, and add time to it, when the time is past a threshold, allow the player to spawn it, and reset the cooldown variable again.

[dry pulsar]

So yeah thats what my Idea was but Idk how to programm it

[hard fossil]

What do you have so far?

[cosmic dagger]

I didn't say any field of knowledge. I assumed we were talking about beginner programmers (hence the channel). It's "better" to use when they have learned knowledge of the subject bcuz they'll know, or at least have an idea when it gives wrong/incorrect results

We've seen, too often, incorrect AI code, or even code they can't use bcuz they don't understand it

This makes it harder for us to help . . .

[cosmic dagger]

Try and break it down into separate tasks/steps. They have laid out most of it (the order) for you . . .

[hard fossil]

I never advocated to use AI to generate code. I'm talking about getting a deeper understanding and explanation of how your code is working, how it can be improved, and what potential bugs it could produce, AI is excellent for this. For example, following many of Brackey's tutorials, one of the biggest Unity tutorial channels, solely, would lead to bad programming practices. If you follow the tutorials though, I'm sure you would learn some helpful things. Now if you took your running code, and wanted to learn more, you could copy and paste parts into say ChatGPT, and it would tell you how you could improve it by doing certain things, why doing things the way you were doing could lead to errors, and why another way is an improvement. If someone doesn't check multiple sources when learning new information, I think that's a whole other issue. I don't think that other issue nullifies the point that LLM's are useful as a learrning aide.

[hard mantle]

For someone that has 0 coding experience, would the junior programming pathway on the unity learn site give me/learn me the basics of unity c# coding? If it does wha would you recommend me do afterwards. And if it doesn’t where should I start

[rich adder]

wouldn't hurt.. though more traditional C# basic beginner courses will be better prior to any Unity API / Concepts

some pinned in this channel, I personally would recommend this one
C# fundamentals (video series)

[keen acorn]

Yeah, personally, I tried going though unity tutorials with no previous coding experience. Not fun. I felt lost most of the times

[rich adder]

They definitely assume you know the basics

basic code structuring, variables etc.

[keen acorn]

I later did the CS50x course online, which i recommend quite a lot. Won't do much advertisement, but it's free, assumes no previous experience, and features quite some good problem sets

[hard fossil]

Try this:
https://www.youtube.com/watch?v=_cCGBMmMOFw&list=PLFt_AvWsXl0fnA91TcmkRyhhixX9CO3Lw

[rich adder]

yeah that one is good knowledge to have, especially Algorithms and big O are important topics in any dev, but gamedev especially when performance can be critical

[twin pivot]

Make a really simple 'game' and when you're stuck try to google it and then if youre still not sure ask help here

[twin pivot]

(Shoutout unity and microsoft documentation)

[cosmic dagger]

Personally, I did the Beginner Scripting, then the Intermediate Scripting tutorials. I would definitely read a blog/tutorials on C# (I did this before anything else) or watch a video on C# fundamentals as well . . .

[hard mantle]

Thanks will check this out

[hard mantle]

Okie thanks man

[hard mantle]

Ok thanks. I have checked out youtube but it seems like a decent chunk of the tutorials are very outdated and it causes problems when I try to follow them

[sour fulcrum]

aside from velocity being renamed everything in old tutorials should work

Feel free to ask about specific problems your running into

[hard mantle]

Oki thanks man

[naive pawn]

input lol

[naive pawn]

additionally from what batby mentioned, unity changed the default "input handling" in 6.1 onwards, so you'll have to configure that back for older tutorials
