because i need the y velocity to become a vector3, cause i cannot just put a float alone there (it's a Vector3 multiplication, plus adding)

[short hazel]

Yep so .NET 5 is an entirely different branch. Unity uses .NET Framework 4.8, which is close in terms of features but has less. Most of the things introduced in modern .NET are syntax shortcuts, so you probably won't hit many errors anyway

[worthy tundra]

_rb.velocity = new Vector3(_movementKeys.x * transform.right, _rb.velocity.y, _movementKeys.y * transform.forward);

you can pass the y velocity of the rigidbody as is if you want it unchanged

[flint abyss]

Ill try to look for more c# tutorials that are on the unity engine

[timber comet]

are you sure this works? 'Cause you are multipling a Vector3 inside a new Vector3

let me test it

[worthy tundra]

oh yeah right wait a sec

[worthy tundra]

_rb.velocity = new Vector3(_movementKeys.x, _rb.velocity.y, _movementKeys.y);

try this one out instead

[timber comet]

the problem here is that the player is not following the direction it is facing

[worthy tundra]

https://pastebin.com/SbDgUaNc

something like this?

[timber comet]

that's why i was stuck before

[worthy tundra]

hmmm let me think

been a while since i wrote a movement code

[short hazel]

No, that starts a coroutine and promptly stops it. I mean something like this

Coroutine c = StartCoroutine(Coro());
// ...
StopCoroutine(c);

[slender nymph]

you need to transform your input direction from local space to world space using transform.TransformDirection

[timber comet]

Like this: Vector2 _LocalMovement = transform.TransformDirection(_movementKeys);?

[worthy tundra]

sorry i cant help, the only movement codes i wrote are based on AddForce(); rather than modifying the velocity i dont have experience in this

[slender nymph]

you need to create a vector3 from the input first

[worthy tundra]

i can save coroutines as variables?

[waxen adder]

I actually just had to do that today lol
Seems a little unintuitive, considering the words used. You'd think "local" would mean you move relative to the player, but that's not how it happens

[timber comet]

dont worry, thanks for the help anyway

[short hazel]

Yes

[timber comet]

ok, will try

[worthy tundra]

ok let me try something

[tepid summit]

wdym

[worthy tundra]

do i call both in the take damage function?

[slender nymph]

sounds like you need to learn the difference between local and world coordinates

[short hazel]

Maybe? Wherever you need to "reset" the timer. If there's a coroutine running, stop it. Then start a new one

[timber comet]

thanks it worked

[worthy tundra]

ok im gonna try the following and then report on the results:

Coroutine c;

void TakeDamageFunction()
{
       StopCoroutine(c);
       c = StartCoroutine(coroutineName);
}

[worthy tundra]

ok i got a null error im gonna check if its null before i stop it

[burnt vapor]

What is the goal of this?

If there is some sort of timed system that must happen then maybe Coroutines are not the best idea. Instead you might want to stick to Update and track timestamps

This works but it can be messy

[worthy tundra]

#💻┃code-beginner message

[worthy tundra]

IT WORKED tysm

[burnt vapor]

Yes, use timestamps instead

When they take damage, set a timestamp for (for example) Timer.time + 5.0 to start healing 5 seconds into the future

You can have a long running Coroutine that checks every frame if the time passed, and if so it stops checking and starts healing every x seconds until the timestamp is in the future again

It's a lot easier than hassling with starting and ending Coroutines

https://docs.unity3d.com/ScriptReference/Time-time.html

[worthy tundra]

thanks but i think im gonna stick with what ive done

[burnt vapor]

Suit yourself

[tepid summit]

Your code was last called there before Unity threw the exception according to your stacktrace

[opaque moss]

I had this

[burnt vapor]

Okay, but what is the code? The code is important here

[opaque moss]

wait

using System.Collections.Generic;
using UnityEngine;

public class CameraManager : MonoBehaviour
{
   public Transform target;
   public float cameraSpeed;
   
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
       transform.position = Vector3.Slerp(transform.position, new Vector3(target.position.x, target.position.y, transform.position.z), cameraSpeed); 
    }
}

[slender nymph]

target has been destroyed but you are still trying to use it

[opaque moss]

how can I fix that

Transfor has been destroyed as well but idk actually how to solve those kinda things

[slender nymph]

check if the object has been destroyed or don't destroy it

[slender nymph]

no it hasn't

the only object on that line that could have possibly been destroyed is target

[opaque moss]

{
    if (target != null)
    {
        transform.position = Vector3.Slerp(transform.position, new Vector3(target.position.x, target.position.y, transform.position.z), cameraSpeed);
    }
    else
    {
        Debug.LogWarning("Target nesnesi atanmadı veya yok edildi!");
    }
}``` ```void OnGroundCheck()
{
    if (groundCheckPosition != null)
    {
        isGrounded = Physics2D.OverlapCircle(groundCheckPosition.position, groundCheckRadius, groundCheckLayer);
        playerAnimator.SetBool("isGroundedAnim", isGrounded);
    }
    else
    {
        Debug.LogWarning("GroundCheckPosition nesnesi atanmadı veya yok edildi!");
    }
}

I implemented those code lines but when the game started, my player was not in the scene

[verbal dome]

So did the log say that target is null?

I mean, did it print the warning in Update

[opaque moss]

yes

[verbal dome]

Do you get any errors in the console when that happens?

[opaque moss]

ı did not get any error but my player was not in the scene

[verbal dome]

Well, how is your player placed in the scene?

[slender nymph]

doesn't look related to the code you've shared at all

[verbal dome]

Yep, separate issue

[opaque moss]

suddenly disappeared

[slender nymph]

also don't crosspost. your issue regarding the destroyed object was already solved before you posted it to the other channel

[opaque moss]

What?

[verbal dome]

Do you have code that spawns the player or where does it come from

You havent show any relevant info about the player disappearing problem

Is there a way I could save a int within the game folder itself? I’ve noticed the most common save places are either in the Registry or appdata but can you do the root folder of the game by chance? I’m trying to save a int

[verbal dome]

1. Put long code in a paste site !code
2. Don't send DM's, it's against the rules and just kinda weird
3. When the player 'disappears', did you try selecting it and seeing where it is in the scene? Or is it completely missing? If so, what should spawn the player to the scene?

depending on the build platform you can save data in Application.streamingAssetsPath

[spare basalt]

hi everyone,can u help me pls?```public void exp1(string Path)
{
Path2 = "Application.persistentDataPath" + Path;

    DirectoryInfo di = new DirectoryInfo("Application.persistentDataPath" + Path); // Not working, only if Path= "" working
    DirectoryInfo di = new DirectoryInfo(Path2); // Not working
    DirectoryInfo di = new DirectoryInfo(System.IO.Path.Combine(Application.persistentDataPath, Path)); // Not working, only if Path= "" working
    DirectoryInfo di = new DirectoryInfo("Application.persistentDataPath" + "/directoryname"); // Working but i dont need this type
}```

how cani fix that?

string Path2 i know

[languid spire]

why are you passing Application.persistentDataPath as a string?

[spare basalt]

what should i do?

[languid spire]

take the quotes off

And, use Path.Combine to build path strings

[spare basalt]

DirectoryInfo(System.IO.Path.Combine(Application.persistentDataPath, Path));

i used

[languid spire]

does Path start with a / ?

[spare basalt]

yes

[languid spire]

remove it

[atomic holly]

Hello,
In one of my function, I create buttons from a buttonprefab like this :

for (int i = 0; i < weaponsInShop.Length; i++)
{
    GameObject button = Instantiate(buttonWeaponToSellPrefab, buttonWeaponToSellParent);
    ItemWeaponButton buttonScript = button.GetComponent<ItemWeaponButton>();
    buttonScript.WeaponImage.sprite = weaponsInShop[i].itemImage;
    buttonScript.WeaponItem = weaponsInShop[i];
}

My ItemWeaponButton script is this :

public class ItemWeaponButton : MonoBehaviour
{
    public Image WeaponImage;
    public Weapon WeaponItem;
}

When I call my function, Unity send me this error : NullReferenceException: Object reference not set to an instance of an object
Why ?

[strong wren]

Because one of the references you are trying to access is null. Narrowing it down to a specific line would help

[atomic holly]

I verify all in Unity and I give all reference

It can be from script or Unity ?

[strong wren]

It should give you more information than you have provided.

There should be a stacktrace in the bottom section of console

[atomic holly]

It's the all error : NullReferenceException: Object reference not set to an instance of an object ShopWeaponManager.CreateWeaponsToSell (Weapon[] weapons) (at Assets/Code/Scripts/NPC/Shop/ShopWeaponManager.cs:57) ShopWeaponManager.OpenWeaponShop (Weapon[] weapons, System.String pnjName) (at Assets/Code/Scripts/NPC/Shop/ShopWeaponManager.cs:39) ShopWeaponTrigger.Update () (at Assets/Code/Scripts/NPC/Shop/ShopWeaponTrigger.cs:16)

[strong wren]

What's line 57 in ShopWeaponManager?

[atomic holly]

buttonScript.WeaponImage.sprite = weaponsInShop[i].itemImage;

[strong wren]

Something on that line is null. You can attach a debugger to inspect each value as the code executes

https://unity.huh.how/debugging/debugger

[atomic holly]

Okay I found, I forgot to give the reference of the Image of the button :/

Thanks to you !

[verbal dome]

Did you check that the methods are getting called? With Debug.Log for example

And make sure that you don't disable the object that has the AudioSource. That would stop the sound

[manic void]

i'm making an inventory system for a 3d unity project. right now i'm trying to add a drag and drop system to the items but it doesn't work.. I only have debug.logs right now and nothing shows up in the console

DragDrop - https://hst.sh/cufazifuva.cpp
ItemSlot - https://hst.sh/movubemodo.csharp

i've read forums talking about adding a StandaloneInputModule to the event system but because im using new InputSystem i need to use a InputSystemUIInputModule. I've added a canvas group to the item, made sure the canvas has a GraphicRaycaster. I also did an Event System debugger - https://hst.sh/musobofono.cpp and still nothing shows up in console. when i click on the item absolutely nothing happens

[rigid ridge]

Hello im still new to this and everytime i try to make movement it says "ArgumentException: Input Axis horizontal is not setup."

[rigid ridge]

Oh alright thanks

does anyone know how i can make the orange object stay on top of the disc when it moves?

cuz its just staying in place when i move away

Child the object or use some kind of constraint

Good night (I personally have a night). I have a question: what function or method is needed to select a color in c\hannel mixer? I tried to write it (no errors came out, but it didn't work). How to do it?

[rare rivet]

It actually is working. It’s just that the layer that you have on the object simply isn’t corresponding to the color values you provided. Unity has a hidden mask on every object accessing the lower layer, so you’re changing the color that isn’t visible

[split dragon]

Ok. Thanks

[stray thorn]

no its a physics object it spawns far away from the disc and when i run into it i want it to stay on top until it gets pushed away by another object

Hi,
I put my code on a github and put at the origin. But I don't see there is a conflict in my scene in Unity. So now, I have nothing in my scene and git say the error is here in my Scene.unity :

[rich adder]

scenes are biggest pain

figure out what you want to do with the new changes (modify the .scene file )

[eager spindle]

git errors look like ```<<<<<<< Updated upstream

• {fileID: 1429456250}
• {fileID: 2037507436}

Stashed changes

[atomic holly]

Yes but if I just delete one of this fileID, it's do nothing

I have the same error

[atomic holly]

The thing is I put the last update a week (yes, it was a bad idea) so I don't very know what I really changed precisely

[rich adder]

it tells you what changed in the file

[atomic holly]

Yes but it's a lot of thing

Show it where are conflits really ?

[eternal needle]

If you dont know what you're doing to edit it manually, I'd probably just go to an old commit where it's working and take the file from there.
To actually edit it you need to remove the lines with arrows and the =====

Those lines are just to indicate where the conflicts are

[atomic holly]

If I delete all lines with the file ID, can I correct the conflicts ?

[shell herald]

im currently building a shop ui and i have buttons that only become interactable if the requirement (money ) is met. however now i have the problem that it is only local to each button, meaning, should the player have 3 items in his shop for 300 cash, and he has 310 in his inventory, he can still buy all 3 because they only check once.
anyone knows how i can "fix" that?

Button script https://pastebin.com/crgwk9qQ

[eternal needle]

Refer to the message above that one. Dont just randomly guess at what to do here.
I dont know what file IDs you want, and just deleting those lines alone wont remove the conflict warning

[desert temple]

So. trying to do something here.

• Creating a boolean value that'll flip between true/false depending on whether or not a certain, already integrated count is met. This will then trigger a win screen when the player hits a simple spot.
  Should I share what I have so far here?

[eternal needle]

Run the same checks everytime something is bought.

yes, but how do i do that across multiple buttons. i want when the player clicks button A, to also refresh on button B

[eternal needle]

Honestly I think you should have your shop more as 1 script rather than what it is currently. But even if you dont go that route, you still need a general "shop manager" so you can have a central place that is notified/notifies other buttons of when an item is bought and it needs updating.
Also you should ideally check how much they have after clicking the button, just as a sanity check.

Idk if this is the same everywhere, but this is not how you spell reduce

[worthy vault]

thanks

[worthy vault]

yes give me

thank you

if you can help me help thanks guys

[eager spindle]

well do you know any programming

c#

java

anything

[steep rose]

im just gonna give a rigidbody tutorial with movement, its very easy for beginners unlike character controller

[eager spindle]

i need to hurry up on my 300 slide C#, Raylib and Unity tutorial for beginners

[steep rose]

personally i would recomend either brackeys, or dave development, i followed these tutorials when i was starting

[worthy vault]

thanks for helping @steep rose @eager spindle

[steep rose]

👍

[worthy vault]

No

[desert temple]

https://hastebin.com/share/qosuvixora.csharp
Got it. Here's the large code.

[worthy vault]

what is it do

[eager spindle]

what's the count here?

you said you wanted something to trigger when the count is met

[desert temple]

There's collectibles you gather in the level.

[eager spindle]

oh I see it

do you already have a function for what you want to do when the count is met?

[worthy vault]

bro i don't learn any developing language

[worthy vault]

No

[eager spindle]

tldr in OnTriggerEnter check if the count is met, then add the function there

OnTriggerEnter increases your count

[desert temple]

void SetCountText()
    {
        countText.text = "Count:" + count.ToString();

        if(count >= 8)
        {
            winTextObject.SetActive(true);
        }
    }

ISo you're saying I should move the if statement to OnTriggerEnter, probably turning it into an elif, I think? Or putting it under the if statement in OnTriggerEnter.

[eager spindle]

before we continue do you understand where SetCountText is called from

[desert temple]

Uh, inside Start(), and OnTriggerEnter()?

[worthy vault]

me ?

[eager spindle]

not you

im helping someone else

go learn c# first

[eager spindle]

yep
so why would you need to move it to ontriggerenter?

[worthy vault]

where fo you learn . give me video 😂

[eager spindle]

also what's the problem here actually

[eager spindle]

already did

as a programmer you need to be able to research on how to do stuff yourself

[eager spindle]

does the winscreen not display?

[desert temple]

This was what I was trying to do.

[eager spindle]

well yes but I dont understand what part you're stuck at

[desert temple]

The winscreen displays, I'm just trying to change that from triggering from collecting all the points

To

Collect the collectibles
When player has moved back to the start, trigger the win message.
This is my actual assignment, with the winscreen being the feedback to the player.

[worthy vault]

you mean in this ?
https://www.youtube.com/watch?v=gB1F9G0JXOo

[desert temple]

I've got the collection part done. I'm trying to handle the rest.

[worthy vault]

oh . this . sorry bro

[worthy vault]

thanks for help me

[eager spindle]

to clarify you want the player to walk back to the start while having 8 points in order to win?

[desert temple]

Yes. There'll be collectibles spread throughout a maze, the player touches them, gets their score up to eight, and then they have to return back to get their winscreen.

[steep rose]

wait what is the problem again?

im late

[worthy vault]

me ?

[steep rose]

nope

[eager spindle]

tldr his current code makes it such that he wins if he collects 8 points
he wants it such that collect 8 points and go back to the start to win

[steep rose]

why doesnt he just check if he has 8 points and is in the trigger

[eager spindle]

have another trigger at the start. when player walks into trigger, check if player has 8 points. if so, win

[steep rose]

what was that

[desert temple]

Okay. So...make like a block or plane, that has isTrigger. But shouldn't it be in void update(), not void start()?

[eager spindle]

erm

youre adding another trigger, that's in ontriggerenter

[desert temple]

Oh. So it should like...

void SetCountText()
    {
        countText.text = "Count:" + count.ToString();
    }
    
    // This is where the pickup stuff goes.
    private void OnTriggerEnter(Collider other)
    {
        if(other.gameObject.CompareTag("Pickup"))
        {
            other.gameObject.SetActive(false);
            count = count + 1;

            SetCountText();
        }
        elif(count >= 8 && other.gameObject.CompareTag("GameFinish"))
        {
             winTextObject.SetActive(true);
        }
    }

No idea if I have the right idea here.

[obsidian shoal]

(this is just a test) why is it printing as soon as i start and space does nothing

yes its in update

[polar acorn]

Because you have nothing inside either if statement

See the green underline at the end?

[languid spire]

misplaced ;

[obsidian shoal]

oh its gotta be at the }

[eager spindle]

what is print actually

also if statements dont need ;

[polar acorn]

https://www.w3schools.com/cs/cs_conditions.php

[obsidian shoal]

ok i fixed it kinda but why is it just doing it one time

[eager spindle]

where is this code placed in?

[polar acorn]

Doing what one time

[obsidian shoal]

update

[obsidian shoal]

printing

[eager spindle]

so when you press space key, it prints one time and never again?

[polar acorn]

Are you pressing space multiple times

[obsidian shoal]

yes and yes

[eager spindle]

it could be that this is on

Collapse

[polar acorn]

Show your console after you've pressed it a few times

[obsidian shoal]

oh

works

thanks

[eager spindle]

you can turn collapse off if you want, but having collapse on shows the number of times gets printed

yuh

[obsidian shoal]

how long of unity learn till yall think im ready for my own project?

[steep rose]

you can start now

if you want

[steep rose]

i did and i still asked for help

you will learn on the way, trust me

[eternal needle]

Without knowing exactly what your end goal is, no one can really answer this. And it's unlikely you know exactly what features you want rn.
If you arent familiar with c# basics, then this will take a lot longer if you just try to start making stuff on your own for many reasons. Things will break, you'll have to learn how to debug. As you get better you'll remake systems that no longer fit your needs

[steep rose]

or this 👆

[eternal needle]

You should be a bit more careful offering advice like this, if you dont have that much experience. From what I've seen you seem like a beginner too.
It isnt about asking for help, if someone tries to start a major project too early they're likely just gonna waste a shitton of time

I have years of coding experience, yet still abandoned my first project I worked on for months because it was too much/too bad

[desert temple]

@eager spindle think I managed it with what I posted?

[obsidian shoal]

i understand c# basics like vector3 movement, if statements, variables, keycode stuff, prefabs and a little more i cant remember off the top of my head

i was wanting to do a fps but thats way out of my league

i think im going to wait till i know sound and anims

[rich adder]

except for ifstatements and variables everything else you mentioned has nothing to do with c# per se, its unity specific

[obsidian shoal]

ig i should have said instantiate instead of prefabs

[rich adder]

still not a c# thing lol

[obsidian shoal]

[rich adder]

don't confuse Unity API for anything else but that

[obsidian shoal]

anyways i know enough c# to make something move

[rich adder]

C# is the language they chose to interact with their engine

[rich adder]

wait till you get into actual heavy logic parts, thats where you need raw C# knowledge. knowing the tools available for you like collections, and all that good stuff

c# basics is thrown around very loosely, just pointing out the unity api / and the native c# knowledge is diff

[obsidian shoal]

okay will do

tysm for your help

[mint remnant]

Up for a challenge @obsidian shoal , try to replicate John Conway's game of life in unity. Fairly simple, but will cause you to think about design and logical flow

[obsidian shoal]

i wouldint know where to start

[mint remnant]

well start by googling what it even is, hte wiki spells it out pretty simplistically

[rich adder]

depends what you're doing, a simple game projects work well

logic heavy games can be simple things battleship, connect 4, tic tac toe

they are simple but complex enough for logic practice

[eternal needle]

I do find it crazy people jump into game dev without knowing what a for loop is

[rich adder]

yupp. I'm just as guilty.
Gamedev is very inviting unlike traditional software development

took me a good month to even remember how to write one without IDE

[lost hamlet]

Lmao

[rich adder]

that was like 4 years ago

anything is possible 😉

[languid spire]

And yet, game dev is considerably more difficult than most 'normal' app dev

[lost hamlet]

Depends

[rich adder]

it can be for sure

[lost hamlet]

On what you consider a normal app

[supple garden]

Does anyone know any tutorial where weapon is separately attached to character and have to sync both animations together to make it look like one? It also has to use transform property whatsoever.

[rich adder]

mainly because there are many different maths involved

unlike traditional software

[lost hamlet]

You can make some simple games using regular app development tools

[rich adder]

i still find Trig scary af

[lost hamlet]

Heck, i made tic tac toe with Svelte

Which is for WebApps/websites

[rich adder]

yeah that was my first react project, but once i found webfront end/backend with c# i ditched js
(yay web assembly!)

[lost hamlet]

I wish i could but I'm addicted to svelte

[languid spire]

Christ I can make TicTacToe with nothing but DOS commands

[rich adder]

old school

[lost hamlet]

Funnily enough my first game was tic tac toe in python. Made on my phone. During a break when i was in an internship back in high school

[rich adder]

lucky. I got into development so late 😦

also we're steering into offtopic

[lost hamlet]

I've got people on my (GitHub) team that have been modding/programming since 12

I wish i did that too

But hey better late than never

Crazy how much i love programming

When working on my own stuff it's equivalent or more entertaining than gaming

[rich adder]

I used to use game maker , thought I'd never be programming, was too diffuclt lol
to be fair GML looks pythony, years later I'm in unity doing c# 😛

[eternal needle]

What do you mean "separately attached"? Like a weapon of 2 parts, nunchucks?
Also this isnt really a code question, you would simply make an animation in whatever tool you want. If the weapon itself has an animation, you just play it at the same time as the character

[rich adder]

anyone else puts a Gameobject property in the interface or there a better way to ever get the gameobject ? 🤔

public interface IDamageable
{
    GameObject Object { get; }
    void Damage(float amount);
}```

in the implemented class i do public GameObject Object => gameObject;

[languid spire]

what would be the point?

[rich adder]

If i ever need to GetComponent on a Interface

[languid spire]

but you can just use Component or MonoBehaviour

[eternal needle]

Im not really a fan of such interfaces in the first place. Are you actually applying this to many different classes? Because if it's just one, it defeats the point of an interface. And usually the logic for stuff that takes damage is always the same.

[supple garden]

I already have animations.. yeah youre right. I'll ask in other channel or something lol

[rich adder]

wdym by that?

[rich adder]

Yeah multiple scripts implement this because they all handle the Damage differently, what would you use instead?

[ripe shard]

this still is useful for decoupling library-type assemblies

[eternal needle]

Probably means that you can store a reference to the component rather than the whole game object

[ripe shard]

I find an explicitly named and typed property on such an interface that makes it very clear it’s only supposed the be implemented with a coupled component/object of that type to be a good thing. It provides a lot of opportunities for communicating intent without coercion.

[rich adder]

that makes sense.
I also don't use it often, usually look for the component directly

[eternal needle]

Ah I guess my point doesnt really apply then here. Though one thing to consider, if you're getting this interface (likely via some physics cast or message) then dont you already have a reference to the game object

[rich adder]

thats true. I realized for physics queries you already have the collider, so if it hits the TryGet you already know thats the correct collider
like when I do cs if (collision.collider.TryGetComponent(out IDamageable damageable)) { damageable.Damage(damageAmount); //is damageable, look for specific thing w collision.collider.TryGetComponent(out SomeOtherComponent sm) }

[steep rose]

whats happening

[rich adder]

waddup

[eternal needle]

Not sure if itll apply to your case too, but in my game I pass more information like who the damage dealer was

If you dont end up using it, it's an easy refactor. If you end up needing to add it, it's somewhat a pain when many things already deal damage

[trail harbor]

Quick question, which way are you guys doing melee damage detection? Just a basic raycast from player body to target or from the weapon itself or weapon collision detection?

[rich adder]

oh yeah I usually do that for my projects, especially when it has ragdoll so I know which direction shot came from and whatnot.
this one is for a simple spaceshooter sample project im uploading for upcoming unity leaderboard tut video 😛
Just making sure I don't upload something too trashh.

felt akward just having interaface with just 1 Damage method inside lol

[rich adder]

I do a spherecast

or an overlap sometimes

depending on the type of melee ( i find raycasts too thin)

[eternal needle]

I barely have interfaces honestly. there definitely are reasons to use them (like anikki said) but if you're just making a basic game, it doesnt really matter imo

[trail harbor]

I'll try that one boxcast didnt seem to do it

[rich adder]

tru I might be overcomplicating it here lol

[rich adder]

they both function exactly the same, except their shape

[trail harbor]

Yes I said it wrong, boxcast was hitting everything the rounded shape seems better

[eternal needle]

Also no need to remove it for something simpler if it works. Like in my game I only have a characters that can be damaged. For awhile I thought to myself "what if I wanna shoot a chair and it breaks" then I realized I wont even have chairs, and it doesnt even fit in my theme. Worst case I can also just make the chair a character. If league of legends can make walls out of a shitton of minions I can make a chair a character

[trail harbor]

ty for answer

[rich adder]

yeah ima keep it for this one, I already have 3 obstacle types would be a huge if statement otherwise to do the same thing, meteors, enemy ships, debrids etc.
Oh wow LoL did that? 😆

[eternal needle]

Yes, jarvan ult is a bunch of minions for example. People have found ways to "expose" them and hook it, stun it, damage it

Many other things are too

[ripe shard]

One thing I’ve found useful in smaller projects (<100k LOC) is to aim for having as few types as possible, ie only for the necessary categories with minimal state. In case of damage I’d aim for modeling all damage types with one data struct, immutable serialized config on the component and a ‚type‘-field (an enum for example) that lets you switch between the different specific behaviors for the various entities that implement the general concept. This helps a lot with noticing gameplay modeling that’s overly complicated, because it encourages you to look for the unifying principles behind your gameplay. As a side effect it makes persistent state easier to implement and maintain across future changes. You’d implement most of this system in one class and split classes more along concerns like input/presentation/logic/etc. than entity-damage subtype.

[sharp hornet]

Hey so I tried to get a personal free license and it didn't appear on my licenses page

What should I do

[young lava]

Hi! So pretty much I've been working on optimizing my game recently. I've been trying to minimize my use of expensive operations such as .Find(""). But I was wondering, how much is an acceptable level of using .Find()? I know an exact number would be hard to do, but I've run into scenarios where I think it would be fine to leave it as it is (as I am not running into performance issues for now). An example would be the visual effects for an attack I have, I need to spawn in five visual objects and access a child transform of each of those visual effects. Would it be fine to use .Find when spawning in these visual effects to get the transforms that I require?

[ripe shard]

Not a code a question. #💻┃unity-talk

[sharp hornet]

Soz

[eternal needle]

Find is never truly needed. If you spawn an object, instantiate returns the object so you already have a direct reference. If you need some child object or component you can always just store that as a reference on a script on the parent object

[rich adder]

thats very helpful, thank you!

[ripe shard]

It’s acceptable during setup of a scene but it depends a lot on what you are doing. Typically you don’t ever need it but it’s a boon for keeping your editor workflow alive. Aim to use it very sparingly and only if you can explain exactly why the other approach (which always exists) is not desirable. As a beginner I’d advise you try to avoid it completely, because avoiding it teaches you a lot about how unity actually works.

[young lava]

Ahhh I see I see. Alright thank you! ^^

[queen adder]

It is completely harmless but I always try to avoid doing this because i hate doing (xxx as Component) and unnecessary reference. I usually create a new whole MonoBehaviour if i need access it's object or component. Yeah you are good for me if you really really want it

[strong wren]

Probably a better idea to expose the actual types/data or have another interface, but I sometimes do it out of laziness

[obsidian shoal]

why is this not working?

to make a random number

for the x cord

[raw token]

That Random call will only occur once, when an instance of the class is constructed.

So it should work, and give you a random float for each component - but it will be same float forever after, since you never update it

[rich adder]

btw -10,10 will give you an int not a float, add f suffix if you want to return a float and make max inclusive

so max will be 9

[obsidian shoal]

what the heck?!?!

[rich adder]

jesus

no

you do not put Access modifiers inside methods

anyway, if its just that 1 float put the Random.Range directly in the new Vector3, no need for a float var unless you want readability ig

[deep fog]

are the how to make a video game and the how to make a 2d game tutorial series of brackeys still viable (not outdated)? I have no prior experience with coding/game development

[rich adder]

they function, are they good ? debatble. his code is not very expandable but they do work

[obsidian shoal]

thank you!

[rich adder]

btw did you see what i wrote about the integer vs float part of Random.Range?

[deep fog]

Thanks! which tutorials would be better in your opnion for a (almost) complete beginner?

[obsidian shoal]

yes

[rich adder]

if you only add 10 and not 10f unity reads it as Int which gives you a max of 9 instead of 10

[obsidian shoal]

learn.unity

[rich adder]

integers and max exclusive

[obsidian shoal]

https://learn.unity.com/

[rich adder]

yes the Unity learn ones are good

they have 2D ones too afaik

[deep fog]

Thanks! I'll take a look!

about challenges can someone give me game ideas or a challenge as well

or does anyone know how to use mlagents with cloud computing

[desert temple]

I've got most of this code working, but I'm trying to figure out how to get the text that says "You Win" to show up, since I think there's something wrong in the script itself.

    void SetCountText()
    {
        countText.text = "Count:" + count.ToString();
    }
    
    // This is where the pickup stuff goes.
    private void OnTriggerEnter(Collider other)
    {
        if(other.gameObject.CompareTag("Pickup"))
        {
            other.gameObject.SetActive(false);
            count = count + 1;

            SetCountText();
        }
        else if(count >= 8 && other.gameObject.CompareTag("GameFinish"))
        {
            winTextObject.SetActive(true);
        }
    }
}

With it being triggered by walking over a plane and hitting it, with the tag associated with it.

[silk night]

add a log to the part where it sets the win text to active and find out if it ever triggers

[cinder crag]

https://paste.ofcode.org/34nRdJ4s6vpLjqJAbRnaZF2 (EnemySpawner script)

so i made a wave system , it works perfect but the problem is , every wave is the exact same enemy which can get pretty boring but i want for lets says wave 4 to have a stronger and bigger enemy that spawns , i searched on yt and goggle but still nth so im a little bit stuck and im not sure how i can do that , if anyone can help that would be amazing and appreciated alot :D

[deft grail]

you always instantiate the 0 enemy, you can first try randomizing the number for some variety

[cinder crag]

no no , it randomizes how the enemies spawn so like it can be the EnemyPerson that spawns first or the BigEnemyPerson that spawns first , it randomized and it spawns the first that is in the list

[deft grail]

so the enemies are random? i thought you said they arent or am i understanding wrong

[desert temple]

I'm not sure how to actually do that.

[silk night]

Put a Debug.Log("TEXT"); in the brackets where you activate the text and watch the console while playing

[desert temple]

In this line?
else if(count >= 8 && other.gameObject.CompareTag("GameFinish"))

[silk night]

in the curly brackets of the else if

[cinder crag]

sorry im probably not explaining correctly , so lets say the first wave starts , it will be a combination of EnemyPerson and BigEnemyPerson that spawn in the enemiesToSpawn list gets the enemies from enemies list where are the enemies that i want to spawn in the wave , it takes them and puts them in enemiesToSpawn in a randomized index and if the enemyPerson is first in that line it puts it into the spawnedEnemies list and spawns it and the next enemy etc , the wave system is nice but the problem is even if im like at wave 10 it will still be the same two types of enemies and i kinda dont want that , i want for every wave to be something new like wave 4 to introduce a new enemy that is faster or stronger etc

hope i explained better

[deft grail]

oh i see what you've done, spawn 1 then remove it from the list ok.
i think the best way to do it is have a list of Waves, and then each wave contain a list of the types of enemies it can spawn
so you can have wave 1 doing A, and wave 10 doing ABCDE of enemies

[deft grail]

yeah is better, hopefully what i wrote above should be understandable

[cinder crag]

its understandable but how can i have a list of the waves with my current system? im a lil bit confused

[deft grail]

create a new script which should just be an empty class thats Serializable i think if i remember right.
in that class you can have a List/Array of possible enemies you can spawn and anything else you want a Wave to contain really.
you then in this main script make a list of this new Wave class

[desert temple]

Okay. It's not even coming up, so, I'm not even sure what the deal is there. It should be.

[silk night]

I would assume you never touch a Gameobject that is tagged GameFinish

[cinder crag]

i just saw this vid and i think it has what i want but not sure how to implement it with my system lol

[deft grail]

yup thats what im talking about

[deft grail]

and then in your script you would have a public List<Wave> Waves;

[cinder crag]

ahhh okay okay but how do i implement it with my current system since i have these

[deft grail]

you loop through the enemies in the current wave and spawn them

[cinder crag]

okay i think the guy in the vid is something like mine , thanks for the help :D

[deft grail]

yeah should be, the whole system is basically the same for most people

[cinder crag]

im a bit confused on this , how do i instantiate the first enemy in the list that needs to spawn?

[twilit dirge]

when I change a sprite during runtime via code, after unloading and reloading the scene it reverts back to its original state

Is there some way to save this permanently?

[frosty hound]

Not without coding a save system

[prime cobalt]

My scene view cam got weirdly tilted is there any way to correct it? Kinda not a code thing but idk where to put this question and it is a beginner thing so...

[frosty hound]

#💻┃unity-talk is for general questions. Click on the transform gizmos at the top right.

[cinder crag]

does anyone know how i can integrate the code from the left with the code from the right aka my code , im not sure on how to make it so it spawns the first enemy in the list of that said curr wave

[teal viper]

• Get the enemy prefab from the current wave
• Pass it into the instantiate

[dapper kernel]

Does anyone know why I might not be able to connect my Unity Cloud to my project?

[cinder crag]

how can i get the enemy prefab from the current wave?

[teal viper]

currentWave.enemyPrefab

Assuming currentWave has an enemyPrefab field and it's assigned.

Or currentWave.GetEnemyPrefab()

[cinder crag]

currWave is just a public int

[teal viper]

Well, you need to store the wave data somewhere.

[cinder crag]

https://paste.ofcode.org/zQRCC3L3ZRBK5WqukD7QV4 all the code is here if needed for the enemyspawner

[teal viper]

I'd have a separate class for the wave data:

public class WaveData
{
    [SerializeField] private GameObject enemyPrefab;
    public GameObject GetEnemyPrefab()
{
   return enemyPrefab;
}
}

Then have an array/list of these to define all my waves.

[teal viper]

It feels like you have several approaches mixed up...

You need to decide what approach you wanna go with and remove the unnecessary code + refactor.

[cinder crag]

so basically if i want to go with the enemy that is first in the list should spawn i should let it how it is or how the guy does it

[dusk tusk]

@teal viper Type or namespace definition, or end-of-file expected

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

public class PlayerController : MonoBehaviour
{
    public float speed;
    public float jump;
    public Rigidbody2D rb;
    public BoxCollider2D bc;

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        bc = GetComponent<BoxCollider2D>();
    }

    void OnCollisionEnter2D(bc col)
    {
        private bool canJump = true
    }

    void OnCollisionExit2D(bc col)
    {
        private bool canJump = false
    }

    // Update is called once per frame
    void Update()
    {
        transform.Translate(new Vector2(speed * Time.deltaTime, 0));
        if (Input.GetKey(KeyCode.Space) && canJump == true) {
            rb.velocity = new Vector2(rb.velocity.x, jump);
        }
    }
}```

Also I guess it didn't really explain it, I'm trying to detect if a collider is colliding

"Access modifiers" like public/private change how other code can see a class's members (it's fields and methods). It doesn't make sense to use them in front of a local variable declaration (the variables you define and use only within a method's body) because they can never be externally accessed.

So like

    void OnCollisionEnter2D(bc col)
    {
        private bool canJump = true
    }

will throw an error, because you cannot use private there.

A few lines are also missing semicolons.

In void OnCollisionEnter2D(bc col) you're also saying that the type of the col variable is bc which will throw another error, as bc is not a type - it's a class field variable. Both OnCollisionEnter2D() and OnCollisionExit2D() receive an argument of type Collision2D - so that's what you should type col with

If your IDE is properly configured for Unity, it should be highlighting these issues

[muted viper]

I think you’d need the ; at the end of the true and false things

oh nvm someone already explained it oops

[dusk tusk]

Alr Imma try both of ur guys's ideas

[dusk tusk]

I'm a python dev, so I'm not really used to the semicolon thing

[mint remnant]

On the bright side, you can put the entire program on a single line

[dusk tusk]

Lol

Tf is error CS0246?

[desert temple]

I did, unless I somehow mispelled the tag.

[raw token]

No one has the error codes memorized. But that particular one is likely complaining about void OnCollisionEnter2D(bc col) because it doesn't know what the bc type is (because it's not a type)

[dusk tusk]

No errors!

[dusk tusk]

Yeah I changed that to collision2d

Alr moment of truth

Does it work?

IT WORKS!!!!

LESSGO

[dusk tusk]

BRO THANK YOU SO MUCH

I THINK I AM OVERREACTING

WOOOOOOO

Ride the wave :)

Cheers! 🍻

[dusk tusk]

although these physics are janky, I'm gonna fix that

[dusk tusk]

Hey one last question

How do you lock the camera's y position?

[raw token]

Is your camera a child of your player or some such, and you're trying to prevent it from jumping up with the player?

[dusk tusk]

Yea

Also btw I'm trying to make an impossible game ripoff

[raw token]

I think in that situation (and assuming that you're not using Cinemamachine), I would take the camera out of the player's hierarchy, and instead create a little CameraController script with a Transform target; field that you can drag the player game object into in the inspector, and have the camera match target's x coordinate in... I think LateUpdate() IIRC?

Alternately, I believe there's a "Position Constraint" component you could slap on the camera and configure it to freeze the y position

[dusk tusk]

There IS a position constraint, but no freezing stuff

Oh nvm

I'm gonna try moving the camera at the same speed as the player, but just in a different script

[teal viper]

A bit late, but when we say error details, we mean the whole message, including the file name, error line and callstack. If you don't know what part you need to share, take a screenshot of the whole thing instead.

Also, C# is not python, I suggest going through the Microsoft C# manual language specifications category to learn how C# is different from other languages.

[cosmic dagger]

i saw this at work and wanted to chime in. you can create a custom args class/struct with IDamageable and other (necessary) params. if you need a component, provide that instead of GameObject . . .

[warm condor]

Hey everyone, can someone explain to me why my animation is very jittery when moving. I made a quick search online and I have found out that you can fix this issue by setting the interpolate enum from non to interpolate. That is what I did and it has become a bit better, but the issue still persist... Are there any solutions here?
Here is a video that shows what I mean:

Visual Studio guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)

[rich adder]

Ohh I see, would something like this be the gist of it?

public class DamageEventArgs
{
    public IDamageable Target { get; }
    public float Amount { get; }
    public Component Source { get; }

[open harbor]

can someone help me why my visual studio code is not autocompleting i even looked at the tutorial bu still nothing

for example the OnCollis is wrote but no autocompleteion

but as you can see i see the folders in the left from unity assets

[cinder mason]

I am doing this to get all the directoryInfos in my games saves folder

IEnumerable<DirectoryInfo> dirInfos = new DirectoryInfo(Path.Combine(dataDirPath, "saves")).EnumerateDirectories();

dataDirPath is the persistentdatapath but this has a count of 0, but when i remove the path.combine and just include the dataDirPath it has a count of 1, (the 1 being the saves folder). There are 3 files in the saves folder.

[open harbor]

@cinder mason do u know how to fix it?

or anyone

[rich adder]

you need snippets for those

also don't tag people into your question

[open harbor]

oh ok sorry

[rich adder]

first fix your project error you got there

[open harbor]

so what shoud i do

yeah

do u want the whole error?

[rich adder]

screenshot it

[cosmic dagger]

yeah, exactly — i have smth similar. you can create an instance of the args and invoke an event that has the DamageEventArgs as a parameter . . .

[open harbor]

whole error

i got more do u want ot see whole?

whole error?

[rich adder]

ahh got it. that makes sense actually. Thanks for tip!

[open harbor]

here is the error in the output

[rich adder]

ok download the .NET sdk then

you need to restart PC after installs

[cosmic dagger]

did you download the .NET SDK?

[open harbor]

ok so shoud i just go to the site linked?

[eternal needle]

id try to define something more specific than Component for the source, but overall similar to what i have too. Because with just Component you cant really do much, you'd have to try casting to every type if you wanted to actually do logic based on it

[open harbor]

i dont really know

[rich adder]

you have the runtimes but not SDK so yes

[open harbor]

ok

[rich adder]

yeah was thinking about that cause i think earlier someone mentioned Monobehavior as choice too. but yeah true about casting it

[warm condor]

hey, can someone help me here, I don't think anyone has responded 😭 #💻┃code-beginner message

[open harbor]

what version of the sdk shoud i donwload???

[eternal needle]

even monobehaviour is kinda useless. you could go with another interface (with similar reasons to the talk like 10 hours ago) if multiple things can be a damage source. Or just an actual specific component that is the true source of anything that did damage

[open harbor]

which version this one?

):

[eternal needle]

stare at it in the scene view, does it jitter there? if not, its the camera thats the one jittering.
camera needs to update at the same rate that the movement does

[rich adder]

are you on windows? pick Windows

x64

[warm condor]

ahh ok I get it. I checked how my character moves in the scene view and there are no jitters, and so that means it is the camera that is jittering. If it really is the updating issue, then how do I update the camera at the same rate as the movement?

[eternal needle]

are u using cinemachine? Theres tons of options for when it should update

[warm condor]

no I have writen my own code for that, here ill show it to you:

    private Vector3 offset = new Vector3(0f, 0f, -10f);
    private Vector3 velocity = Vector3.zero;
    public float smoothTime;

    [SerializeField] private Transform target;
    void FixedUpdate(){
        Vector3 targetPosition = target.position + offset;
        transform.position = Vector3.SmoothDamp(transform.position, targetPosition, ref velocity, smoothTime);
    }```

[eternal needle]

im not entirely sure myself how people write cameras following rigidbodies properly, i just use cinemachine. im surprised interpolate didnt make this worse though, because interpolate will move the rb every frame to create a smoother look.

[cosmic dagger]

did you try placing the code in LateUpdate?

[eternal needle]

LateUpdate with interpolate should be ok, though not really sure what people do without interpolate on

[warm condor]

ok, so it looks like I was wrong about how interpolate is making things better. I just put it to none and then everything works better... I don't understand how did it work better before xD

[cosmic dagger]

there are some tricks. you can create an empty child GameObject to the player and use that as the target (with your camera follow code in LateUpdate). it shouldn't jitter since the child GameObject is not moving using a rigidbody . . .

[warm condor]

yea that is exactly what I did, except for the fact that I did not use LateUpdate in the script

[open harbor]

thank you I adjusted some settings and its working thanks bro you're the best! I had it broken for 2 years lol

[open harbor]

is here any suggestions / feedback channel i can out my work?

I have this method and it should copy a prefab and paste it into a specified parent. I can see copies of these prefabs appearing in the hierarchy, but they are invisible. If I personally add a prefab to the hierarchy on the stage, it will be visible. Are there any errors in this method? 
Prefab look like this
-# This is not the full code. If you need more information on this - please tell me.

[cosmic dagger]

is the prefab set to active (enabled) in your project?

also, the slotPrefab variable should be a SlotUI type. this avoids using GetComponent to grab a reference to it . . .

oh, i see. you get multiple components from newSlot (the prefab). you could have a script on the prefab with a reference tot he SlotUI and Button components. then the slotPrefab variable would be the type of the script, and you'd access the slot and button components with newSlot.SlotUI and newSlot.Button . . .

[muted narwhal]

Alright, thank you, let me try

Like this?

[cosmic dagger]

you'd create a separate script that references the SlotUI and Button components

// Place this on the SlotPrefab GameObject
public class Slot : MonoBehaviour
{
    [field: SerializeField] public SlotUI SlotUI { get; private set; } // Assign from the inspector
    

    [field: SerializeField] public Button Button { get; private set; } // Assign from the inspector
}```
then in your code, you can access the components straight from the instantiated object . . .
```cs
[SerializeField] private Slot slotPrefab; // Change the type to the Slot component

// somewhere in your code . . .

var newSlot = Instantiate(slotPrefab, parent); // Returns a reference to the Slot component
var slotUI = newSlot.SlotUI; // Access the SlotUI reference (property from the Slot component)
var button = newSlot.Button; // Access the button reference (property from the Slot component)```

[muted narwhal]

Oh, thank you!

[cosmic dagger]

test it and check for errors (written without an IDE) . . .

I am doing this to get all the directoryInfos in my games saves folder

dataDirPath is the persistentdatapath but this has a count of 0, but when i remove the path.combine and just include the dataDirPath it has a count of 1, (the 1 being the saves folder). There are 3 files in the saves folder, yet it doesnt return any directory infos?

[rich adder]

are you looking for files or folder? i'm confused

[cinder mason]

im looking for the json files in the saves folder

[rich adder]

cause DirectoryInfo returns well directories.

Just use FileInfo

IEnumerable<FileInfo> fileInfos = savesDir.EnumerateFiles();
foreach (var fileInfo in fileInfos)
{
    Debug.Log(fileInfo.Name);
}```there is also 
`FileSystemInfo` to get both since they derive from it

[worthy vault]

ok . thanks

[worthy vault]

bro i have another question and it's my last question

in the video . he using C#
is it for this game . or is he learn C#

sorry if i can't say my mean

[eager spindle]

he learned c# and programming before starting unity

You should too

[slender nymph]

c# is c#. it doesn't suddenly start working completely differently just because you're using unity

[eager spindle]

All the first game devs specialised in Computer Graphics in compsci, programming in C

There was no Unity

There was no Unreal

Only programming in C

This should be the attitude you have before working with game engines, understand that you won't always have access to them

[languid spire]

lol, most of the time we had no OS only BIOS

[eager spindle]

Learn programming before you start

[eager spindle]

I wasn't around during that time but I wonder how devs developed for different platforms

[languid spire]

really there were only 2 platforms, 8080 assembler or 6502 assembler

[eager spindle]

Ah

I need to try my hand at making games for those platforms eventually

[worthy vault]

you mean i have to learn C# first and after that i go to learn unity ?

[eager spindle]

yep you'd learn things faster than way

[wheat wave]

it's not a strict requirement, but it is REALLY helpful

I went straight into unity after I got fed up with using Scratch to make games, I would not recommend that

[languid spire]

yeah, learning to program with Unity if you are already a competent programmer in almost any language is much less painful

[fierce geode]

Are the names of the virtual axes, like the names in the Input Manager stored anywhere?

[languid spire]

ProjectSettings->InputManager.asset. It's a scriptable object

[eager spindle]

when I first started out I didn't know what using was, what MonoBehaviour did, what's the difference between defining my variable in a class vs defining my variable in a function

it did not work out well for me

[languid spire]

That does not surprise me. What so many people fail to realize is that you must first learn the concepts of programming, only then can you apply syntax to actually do something

[topaz mortar]

I have an Item class and then several item type classes: Weapon, Armor, Spell, Scroll, ...
Weapon & Armor need a variable isEquipped
My Item class handles dragging, since all items need to be draggable
But then depending on the isEquipped variable (which is not in Item, but in Weapon and Armor) I need to do something different with the item when dropped
Is there any way to get this IsEquipped variable that is not in Item without having to create another class like Equippable?

For example, when selling an item, which is again possible for all Items, I don't want an equipped item to be sellable
Another example, when dragging an item on an EquipmentContainer, it needs to be equipped, unless it is already equipped

        {
            // Get our item
            Item droppedItem = eventData.pointerDrag.GetComponent<Item>();

            // Don't do anything if item is already equipped
            if (droppedItem.isEquipped)
            {
                return;
            }```

[languid spire]

That sounds like isEquiped should be in an Interface which may or may not be inherited by your Item sub classes

[topaz mortar]

I know what interfaces are and how they work, kinda, but never used one
How would that solve my issue?

[serene briar]

Hi. So I have
Mathf.Pow(6.6743, -11);
to represent newton’s universal gravity constant. For some reason, that outputs “8.541544e-10”. As far as I can tell, that number is significantly higher. Why might this happen?

[eternal needle]

do you know scientific notation? this number is basically 0

[languid spire]

it would allow you to add the isEquiped variable to some but not all item classes

[serene briar]

Yes I know scientific notation very well. Gravity is a weak force. That’s the number used in real life.

[eternal needle]

then whats the problem? 6.6743^-11 is indeed 8.541544e-10

[topaz mortar]

but why would I use an interface for that instead of just adding the variable to the class?
also doesn't solve my issue of Item not having the variable, or would I just put the interface on Item too, but then it's basically on all the classes that inherit it too?

[languid spire]

because then you can cast to the Interface type for all item classes, if the result is not null then you know that isEquipable is implemented

[serene briar]

I guess it’s just the exponent changing that’s weird. Also, when I put numbers into a calculator to determine orbital velocity, the normal -11 constant gives a drastically smaller number than the -10

[topaz mortar]

how would I cast to the interface type?

[languid spire]

like any other cast

[topaz mortar]

so it's the same as casting Item to Weapon or Armor?

[languid spire]

yes

[eternal needle]

im not sure what you mean, the "normal -11 constant gives a drastically smaller number than the -10". e-10 does not just directly mean exponent. it is 8.541544 x 10^-10

but id honestly be surprised if you get accurate calculations with such a small number

[broken cargo]

I don't think floats are precise enough for e-11

[topaz mortar]

cool thx 🙂

[slender nymph]

floats are only precise enough for about 8 significant digits

[languid spire]

imagine this

public class Weapon : Item, IEquipable
public class Axe : Item, IEquipable
public class Bottle : Item
...
List<Item> items
...
IEquipable iq = items[i] as IEquipable
if (iq != null) { // Do Equipable stuff here ?

[serene briar]

Oh so the number is just not able to get down to e-11 essentially? And kinda freaks out when it tries to?

not really, but float math wont be at all accurate like this

not really meaning its not about it freaking out. its just about values that cant be represented

[slender nymph]

well those numbers are also so incredibly small that they are effectively 0. and due to floating point inaccuracy the values may not be able to be precisely represented so may appear as some slightly different value. they are still effectively 0 though

[topaz mortar]

Does this look ok?
https://gdl.space/konevuwazo.cpp

[slender nymph]

if you're on 2021+ you can combine the cast and type check into one line instead of doing it separately: if(droppedItem is IEquippable equippable)

[serene briar]

So the number is the same but looks different because floats can’t show that number? But it is still the same?

[safe radish]

im working on a cell based fluid sim, currently cells on the same y keep causing stackoverflows because they keep giving their fillAmount back and forth to eachother. how do people normally solve that problem? i was thinking to either save the newly added neighbours on the cells themselves or making a list of already edited cells and clearing it every iteration

[languid spire]

looks OK

[topaz mortar]

cool, my first real use case for an Interface!! 🙂

you'll make a real programmer out of me yet!

[slender nymph]

both of those numbers are so incredibly small that they can just be treated as 0

[languid spire]

lol

[eager spindle]

add a limit to the amount of times you iterate the fluid amount

not sure what your code looks like rn

[serene briar]

So there’s just no way to use a float to accurately represent a number that needs to be small and precise?

[slender nymph]

please go learn about floating point accuracy in computing

[eager spindle]

There might be a package out there that has a more precise float, but just know that everything a computer does is approximations

The end user does not need perfectly computed numbers

They are not scientists

[eternal needle]

here, you can see this and realize what you're doing wont work
https://dotnetfiddle.net/n9EhIf

[slender nymph]

sure there are other, more precise, data types. but that won't help when they are forced to use floats because that's what unity uses for everything. so all their worrying about these numbers that are effectively 0 is absolutely pointless

[safe radish]

been trying different things. right now i'm storing the fillAmount on the pure class fluidcells and calling for spreads if their own fillAmount is over the threshold for spreading. only when they get water added

guess i could add a flag in there that resets every iteration

for context, if you know of the game. i'm pretty much trying to recreate the fluid mechanics of timberborn

[serene briar]

Last question: If I don’t store it as a float in the first place, and instead just use the Mathf.Pow directly in an equation, would that work instead?

[slender nymph]

Mathf.Pow uses floats

[serene briar]

dang it

[slender nymph]

you're not really going to find anything in the unity engine that uses any more precise data types than float

[eternal needle]

the f in Mathf might stand for something

Maybe describe your use case more. Im not a big physics person but what do you actually plan to do with these numbers? If this is a one time calculation, then i see no problem with storing these as doubles initially and then converting them to float for the actual unity usage.

[serene briar]

It’s a simulator essentially that needs that tiny number to calculate the force of one object on another

And so it’s not possible to use a double float in calculations?

[languid spire]

yes you can use a double in your calculations but you must convert the result to float in order to pass that to any Unity method

[eternal needle]

you'll also need to keep track of all these values yourself. it'd be inaccurate for example if you read the current position from the unity object (since thats 3 floats) and used that in your calculations with doubles to set the next position

[topaz mortar]

I'm trying to set up an event system to equip my weapon
When I drag/drop my weapon on equipment it correctly sends the event to my Inventory
But how do I get the dropped weapon in my Inventory script?

Yes, this throws a syntax error:

GameObject gun = transform.GetChild(

[pine furnace]

oh

i forgot to take it out

ignore that

[willow scroll]

Read the error

[slender nymph]

use Action<Weapon> instead of Action since the latter does not allow a parameter to be passed

[topaz mortar]

yeah that's what I was missing, thx 🙂

[slender nymph]

also why does this inherit from monobehaviour if the only members are both static and it doesn't use anything that needs the MonoBehaviour inheritance

[topaz mortar]

dunno, I just followed a YT tutorial that had me put it on an empty gameobject

[slender nymph]

well that's entirely pointless

[eternal needle]

Amazing

[willow scroll]

Perhaps, this is just a start and new methods, suitable for MonoBehaviour, are going to be added soon

[willow scroll]

Read [this](#💻┃code-beginner message) first

[topaz mortar]

yeah I guess I don't need that 🙂

[willow scroll]

Your code decreases the character's height by 2 when crouching. Seems fine to me, what's the issue?

[serene briar]

I got it now. I just set my variables and constants from floats to doubles and the Math instead of Mathf. Thanks for the help though (from everyone else too) I learned what I needed to

[pine furnace]

is there a way to only change the scale of the parent

and keep the scale of the children normal

or i need to do a for and go through all the children and double the value?

[willow scroll]

Yes, I suppose, that's what you would do

[pine furnace]

why it doesn t find my child

by name

i fixed it

is this efficient

to scale back all the children

[topaz mortar]

What does this mean? "Default references will only be applied in edit mode."

[slender nymph]

it means exactly what it says. the object you drag in there will only be applied to instances of that object created via the editor. using AddComponent in code will not assign that field automatically

[topaz mortar]

yeah that's what I thought, not very clear though

[fierce locust]

Hello, I'd like to make a system to place blocks with unity, it doesn't work, the block doesn't move to the end of my player's raycast, I use a layer so that the raycast doesn't interfere with the player

public class Build : MonoBehaviour
{
    [SerializeField]
    public GameObject blockPrefabs;
    void Start()
    {
        this.blockPrefabs = Instantiate(this.blockPrefabs, new Vector3(0, 0, 0), Quaternion.identity);
        
    }

    // Update is called once per frame
    void Update()
    { 
        RaycastHit hit;
        if (Physics.Raycast(camera.ScreenPointToRay(new Vector3(Screen.width / 2, Screen.height / 2, 0)), out hit, 10, LayerMask.GetMask("Player")))
        {
            this.blockPrefabs.transform.position = hit.point;
        }
    }
}

[slender nymph]

I use a layer so that the raycast doesn't interfere with the player
that's basically the opposite of what your layermask is being used for. it will only detect objects on the layer named Player

https://unity.huh.how/physics-queries/layer-masks

[winter tinsel]

timescale is 0 but game continues to spawn prefabs ?

[barren vapor]

depends on it. If you use a time based timer to spawn prefabs and it doesn't get reset back, then it keeps on spawning. Or you're probably using a non-time based timer

[winter tinsel]

yea

im checking by a integer that counts up

untill a certain value

then gets reset

[slender nymph]

show code

[barren vapor]

can you share the code?

[winter tinsel]

the integer counts up to 200 then gets reset

aswell as the object being instantiated

[slender nymph]

that code is not only framerate dependent (so faster on higher framerates) but has nothing to do with the timescale. except, of course, for that erroneous deltaTime multiplication in the velocity assignment

[winter tinsel]

how do i make it time depedant?

[barren vapor]

szooczt += Time.deltaTime;

[slender nymph]

make your szooczt a float instead of an int, and increment it by deltaTime. then instead of using that arbitrary 200 unit, compare it the number of seconds you want to pass between spawns

[winter tinsel]

so im guessing 1 is 1 second?

like by using time.deltatime

szooczt would increment by 1 second?

[barren vapor]

there are 60 frames a second, so it would get incremented by 0.06 each time if my math is correct.

[slender nymph]

it is not

[barren vapor]

0.0167*

oh wait. It's time bound, so it depends on the time itself

[half egret]

That's if it's a solid framerate, deltaTime retrieves the time since the last frame to be more specific

[barren vapor]

I think

[languid spire]

share your !code

[toxic cloak]

and i dont have cinemachine imported

[languid spire]

then why are you asking in a code channel?

[toxic cloak]

Yeah thanks for the great help

[languid spire]

ask in the correct channel and you might get some, over entitlement problem on your part

[sullen zealot]

hello how can i set a coroutine to null after its finished?

[half egret]

What do you mean exactly? Do you mean a coroutine reference?

[ivory bobcat]

What components are you using on object that you're trying to move?

[teal viper]

coroutine = null;

[ivory bobcat]

If you're using a Character Controller, it ignores modifications to the Transform component

And what else?

[polar acorn]

Show a screenshot of the inspector of it

[sullen zealot]

is there a way to do it like this?

private Coroutine myCoroutine;
IEnumerator MyCoroutine()
{
  //Code
  
  //Set coroutine to null
}
private void Func()
{
  myCoroutine = StartCoroutine(MyCoroutine())
}

[polar acorn]

yes

exactly like that in fact

[half egret]

I don't remember the exact type for coroutines, but yes that should technically work

[sullen zealot]

like this?

private Coroutine myCoroutine;
IEnumerator MyCoroutine()
{
  //Code
  
  //Set coroutine to null
  myCoroutine = null;
}
private void Func()
{
  myCoroutine = StartCoroutine(MyCoroutine())
}

[half egret]

Yep

[sullen zealot]

thanks

one more thing

does stopping a coroutine whit the StopCoroutine(coroutine) makes it null?

[languid spire]

no

[sullen zealot]

oh ok

[polar acorn]

Try disabling this script and then trying again.

Also, when you say it "has no effect", do you actually have non UI elements in the scene to actually see the camera moving?

[toxic cloak]

i have a background which i can spot if the camera moved

[cosmic dagger]

If you don't assign it null, it's not null. You're just stopping its execution . . .

[polar acorn]

How did you do the background? Is it a sprite renderer?

Show the inspector of that

[toxic cloak]

ui image

and tried with a sprite renderer too

[polar acorn]

So, a UI Image

that is meant to move with the camera

and not move

That is how you're determining the camera isn't moving

[toxic cloak]

no i am looking at the transform position of the camera which should change right when it moves

[polar acorn]

Yes, but you said it wasn't working even if you changed those by hand. That would be because UI Overlays follow the camera

[void thicket]

You are always subtracting same thing here?

[polar acorn]

yes

[void thicket]

direction is always zero

[burnt vapor]

I thought there was no code related to your problem? This is why context in your question is important

It's not mentioned to bully or annoy somebody, there are different channels for different problems

[void thicket]

Perhaps you wanted GetMouseButtonDown for the first if condition

Debug.Log what value you are getting

[muted wadi]

Could I get some tips on how to code a visual indicator for a lock on system? Something like the Huntress' bow aiming from Risk of Rain 2. I'm thinking the best way would be to set up a system that moves around the indicator through a UI canvas and changes its size and position based on the distance the enemy is from the player and whether or not they're on the screen.

it seems to be the most effective way but there could always be something better

[obsidian shoal]

what variable type would i use to make
Input.mousePosition
into a variable

[tawdry quest]

badly presented question, look below for a better phrased version

[muted wadi]

vector3

[languid spire]

if you hover over mousePosition in your IDE it will tell you

[cosmic dagger]

Look at the Unity docs to see what type mousePosition is . . .

[muted wadi]

also i would recommend just using Vector2 for mouse positions because your screen is 2D, so it only needs the vertical and horizontal coordinates of your mouse. I'm not really how sure how the third vector would make an appearance

[teal viper]

You just do string formatting.

[tawdry quest]

so just grab the local string and then attach the number, i have never worked with localisation

[teal viper]

This is not as much localization as just the basics of working with strings.
String.Format()
https://learn.microsoft.com/en-us/dotnet/fundamentals/runtime-libraries/system-string-format#get-started-with-the-stringformat-method

[tawdry quest]

but i want to work with the unity locale package ?

to translate to the correct language

[teal viper]

Why would that matter?

[tawdry quest]

what ?

[teal viper]

I don't know how you're using the localization package, but it probably just provides you a string in the correct language. After that you can use the string formatting to add your stats/numbers

[tawdry quest]

im confused on how to even access the localized string via code, the only stuff i really find is to use an extra script to attach to your game object that then replaces the text on awake

i guess i could run a script on start then that grabs the number and appends it to that textbox

[teal viper]

Well, solve one problem at a time. String formatting is one problem. Using the localization package correctly is another. Research them in order.

[tawdry quest]

i dont care about string formatting never asked for that

[teal viper]

Didn't you ask how to put numbers in the middle of your text?

[tawdry quest]

i want to load the correct localized string and then append the number

[teal viper]

And that's exactly what string formatting is for

[tawdry quest]

the problem is that currently the only way i know of using localization is that extra script to attach to your game object that then replaces the text on awake

[teal viper]

The appending numbers part

[teal viper]

Yes, you'll need some code to set the correct string to the text component

[tawdry quest]

correct

how

[teal viper]

How what?

[tawdry quest]

let me rephrase my question, maybe the problem is how i asked it

gimme a sec

[uncut dune]

can I access the material of a particle subemmitter with a script and change properties in it for each particle?

[tawdry quest]

Question:
How can i load a string from the Localisation Feature of Unity via Code ?
I only found something tedious where i have to do something {value} to a smart string, but that sounds overly complex.
I would like to use something like this, but i couldnt find anything

text = Locale.LocalisedString(tablename,key)
text = text + damagenumber

[teal viper]

Did you research how to use the localization package? Did you look at the docs?

[tawdry quest]

Yes, i looked trough this and couldnt find anything that resembles what i want
https://docs.unity3d.com/Packages/com.unity.localization@1.5/manual/Scripting.html

As i said i found Smart String which kinda resemble what i need, but it seems rather tedious then just grabbing the string and adding my number via code

https://docs.unity3d.com/Packages/com.unity.localization@1.5/manual/Smart/SmartStrings.html

[teal viper]

I've never used that package, but it looks like localizedString would be enought for your use case. You just need to format the returned stringed, as I mentioned earlier.

https://docs.unity3d.com/Packages/com.unity.localization@1.5/manual/Scripting.html#localizedstring

[tawdry quest]

im actually blind

if i follow that LocalizedString to its implemtation stuff
https://docs.unity3d.com/Packages/com.unity.localization@1.5/api/UnityEngine.Localization.LocalizedString.html
i can see how to access it

but i can also see that the implemtation via Smart String isnt actually that hard

thanks tho

[teal viper]

Smart Strings are a powerful alternative to using String.Format

It seems like they just do some more stuff for you.

[uncut dune]

can I not get the rendering material of each particle to change its properties?

[eager spindle]

what's particles?

[rich adder]

https://docs.unity3d.com/ScriptReference/ParticleSystem.Particle.html no material prop here

[rich adder]

We don't support multiple materials within a single particle system. All particles will be rendered using the same material.
https://forum.unity.com/threads/multiple-materials-in-particle-system.1204639/#post-7698733

[uncut dune]

I see

[uncut dune]

yah I checked that, I also cant find the one the way to change it in the whole particle system

[void thicket]

That’s pretty much the point of particle system

[uncut dune]

it is a subemmiter but I can just change its own particle system

[rich adder]

It has a renderer

[uncut dune]

I know but I mean changing material properties

[rich adder]

In what way? Particles also have their own shader

[uncut dune]

like I have a material I set to be the particles material

and I wanted to access that material and change the properties of it in runtime

[rich adder]

Keep in mind when you modify a new instance is created

You can use .sharedMaterial if you want , then modify whatever you want

[uncut dune]

wont that change for all the objects with that material?

[rich adder]

Yes

[uncut dune]

but I wanted to change it for each particle system

I just wanted my material to have like a "start anim"

so something happens when it appears but Time doesnt work for that since it starts counting since the start of the game

[rich adder]

Why not make w timer and just swap material instead of directly modding it in the shader

[uncut dune]

so swapping the material to make it look like its animated?

I thought setting a property would be less expensive

[rich adder]

Well no you're creating a new material when you modify it

[uncut dune]

I see, thanks

so what is the syntax to access it directly?

something like particleSystem.renderer.material?

[rich adder]

.material

Yea

[uncut dune]

thanks

[winter tinsel]

uh, i have a very weird unity... is it a bug or am i just doing something wrong?

basically

one of my buttons dont work

and i dont know why

it worked fine

i added another canvas to make a pause menu, but even when removing it still doesnt work???, the button doesnt let me click it

[polar acorn]

Do you have an event system in the scene

[winter tinsel]

wdym

[polar acorn]

I mean do you have an event system in the scene

[winter tinsel]

why would that effect wether a button is clickable

[polar acorn]

Because that is literally the component that makes buttons clickable

[mint remnant]

you might just try going to the history panel and clicking back to before you added the canvas

[winter tinsel]

the event is if a certain bool is false make the canvas which has a child that is the button, visible

[polar acorn]

what event?

[winter tinsel]

the weird thing is i remove the canvas and the button STILL isnt clickable

[polar acorn]

I'm asking about an Event System

an object

is there one in the scene

[winter tinsel]

that handles events?

i mean not really?

[polar acorn]

If there is not an Event System in the scene, that would be why your UI doesn't work

[winter tinsel]

theres nothing that specifically uses Event and each indiviual gameobject has its own script

i dont get what you mean by event system

[polar acorn]

I mean an Event System

[winter tinsel]

oh dear

[polar acorn]

The object named Event System that has an Event System component on it

[mint remnant]

IE delegates

[winter tinsel]

gameobject named eventsystem

that has an eventsystem gameobject?

i mean component*

[polar acorn]

Whenever you first create any UI element in a scene, it will also create an Event System. That component is what makes UI work

don't remove it

[winter tinsel]

i havent touched anything

[polar acorn]

Notably, it doesn't get auto-created if you instantiate a UI element from a prefab

So, check your scene. Do you have an Event System in it

[winter tinsel]

i dont know what im looking for

nvm

[polar acorn]

#💻┃code-beginner message

[winter tinsel]

im blind

its there

eventsystem is there

but i havent used it?

[polar acorn]

It literally just needs to exist

that's it

[winter tinsel]

well in that case ys

its there

[polar acorn]

But it does have useful debugging features, if you look at the window on the bottom of the inspector of it while you're running the game, it will tell you what your cursor is hovering

Hover over the button that isn't working and see what it says you're hovering over

[winter tinsel]

ok

ok first of all

i hovered over it and it said text, and the button didnt work, but it worked before, so okay idk maybe something changed so i made the textbox smaller and now it tells me i hover over either the text or the button and when i click the button it STILL doesnt work??

[polar acorn]

If it says you're hovering over the text, then that is the thing you're clicking on, rather than the button. If you don't want to be able to click on that object, uncheck the "Raycast Target" checkbox on that object

[winter tinsel]

okay

button still doesnt work

[polar acorn]

Does the Event System now show that the button is the thing you're hovering over

[winter tinsel]

yes

[polar acorn]

Does the button have any sort of animations or response to hovering over it?

[winter tinsel]

no

if i try to click it nothing happens,

not even the weird tilt the other buttons have

[polar acorn]

Can you show the inspector of the button, and the event system when you're hovering it?

[winter tinsel]

that makes it slightly darker yk

[winter tinsel]

what parts do you need

heres this just so you can rule out that it has no script

[polar acorn]

If you can get the whole button inspector that would be nice

[winter tinsel]

wait a min

i just saw something in the inspector

in eventsystem

it says im hovering over the button but its not eligble for click?

[zenith crown]

Why does this not work?

[polar acorn]

Movement is not a function

It's a Character

[zenith crown]

oh

well what should i do then?

[polar acorn]

What are you trying to do

[polar acorn]

What are you seeing?

[winter tinsel]

exactly what i said

let me

send a pic

[zenith crown]

Make the Vector3 into movement direction

[polar acorn]

How do you intend to move
