[quick pollen]

at least it works

theres still some bugs tho

[rich adder]

you will never NOT have bugs lmao

[quick pollen]

sometimes it straight up takes 5 seconds to do the animation

idk why

it should be an instant transition

[swift crag]

sounds like you need to have a look at your animator controller

[quick pollen]

maybe it has to do with

oh yeah I know

I only make a transition from idle

[swift crag]

notably, if something has an exit time, then the transition can only happen at the exit time

[quick pollen]

doesnt have exit time

altho this is actually perfect

[swift crag]

if your idle animation is, say, 5 seconds long, and you have a transition with an Exit Time, it can take up to 5 seconds to hit the exit time

if there is no exit time, then the tranisition will happen immediately

[quick pollen]

I could force the player to stand still in order to cast the ability, which was my goal

[swift crag]

so if it isn't the animator controller, it's your code's fault

of course, you could be getting stuck in another state that doesn't transition back to Idle for a while

[fair temple]

my raycast cant detect my prefabs

        private void HandleInteractions()
        {
            Vector2 inputOfVector = new Vector2(0, 0);
            Vector3 moveDir = new Vector3(inputOfVector.x, 0f, inputOfVector.y);

            float interactDistance = 2F;
            
            if ( Physics.Raycast(transform.position, moveDir, out RaycastHit raycastHit ,interactDistance) )
            {
                Debug.Log(" - " + raycastHit.transform);
            }
            else
            {
                Debug.Log("No Hits");
            }
        }

[quick pollen]

@swift crag

[quick pollen]

altho the way I did it is pretty cool like this

you can basically queue abilities

[rich adder]

is there a question here?
oh nvm just scrolled up 👍

[quick pollen]

and it plays when you stop moving

[fair temple]

yeah

look upper

[quick pollen]

altho im probably just gonna use an any state

[fair temple]

this one

[verbal dome]

new Vector2(0, 0)?

[rich adder]

start by Debugging what it is hitting

if at all

[fair temple]

oky

[rich adder]

oh yeah Input vector is zero

what gives

[fair temple]

it gives me this thing

[quick pollen]

@swift crag using any state is better tho I suppose
now I just need to figure out a good way to stop all motion

[rich adder]

well either way your moveDir is wrong

[swift crag]

you are explicitly making a [0,0,0] vector in your code

[rich adder]

also you are meant to debug the collider.name

[swift crag]

of course the raycast does not go anywhere

[quick pollen]

ty tho

[fair temple]

but what should i do

[swift crag]

not do that

[summer stump]

Make it not zero

[rich adder]

don't assign zero?

[swift crag]

presumably you want to use your movement direction from somewhere else in your code

[rich adder]

why call it inputOfVector if you are not capturing any inputs with it..

[quick pollen]

instead of multiplying the player's speed by 0 I just straight up turn off the script that handles all that stuff lol
this will cause problems later

[rich adder]

live in the now amirite :?

[quick pollen]

for real lol

that script also handles things like

gravity

camera changes

[rich adder]

thats a big script

[quick pollen]

but tbf the ability does make you float, so having gravity turned off kinda makes sense

[rich adder]

maybe do just set move vel to 0

[quick pollen]

its actually not

the entire thing is like 120 lines

I can probably have a different script just for camera changin tho

just so it doesn't turn off camera switching

[rich adder]

i would not even dare to add a camera switching method or system inside a player move script :

maybe couple of years ago lol

It only makes sense a camera switching functionality has its own script..

[quick pollen]

yeahhh

I mean

I put it there because I had something with moving faster in one of them I think

i cant remember

[rich adder]

yah when you start having other scripts handle other aspects of your objects that will it gets a bloody mess

I had helped someone fix their project they were literally modifying Timescale in like 4 different places wondering how which one now causing unwanted behaviors

if you had a single script only handle timescaling , there is no second guessing

[ember tangle]

should a state machine be made using abstract classes or interfaces?

[rich adder]

or start simple and use an enum

[polar acorn]

yes

[ember tangle]

I have it with abstract classes but since no function is actually implemented in the abstract base class I feel that it would be just as good using Interfaces... Googling is inconclusive.

[swift crag]

A base class for the states makes sense.

Notably, you might want to add some common functionality, like...

public virtual bool CanEnterState(State previousState)
{
  return previousState == null || previousState.priority < this.priority;
}

e.g.

[ember tangle]

I didnt know you could use the || in the return statement

[swift crag]

You can use it anywhere! It’s just an operator

[ember tangle]

hmm I don't know if I understand how that line works. What triggers the 'or' operator?

[golden blade]

Question, can I have multiple scenes running at once and use cameras and render textures to disply each scene onto one partitioned canvas?

Idk how to explain it

[rich adder]

if either one is true it returns true, otherwise it returns false

[eternal needle]

It's the exact same thing as using it in an if statement

[ember tangle]

oh its like shorthand right?

i think I understand

[eternal needle]

No it's not shorthand, it just is. These are boolean expressions, the method returns a bool

[polar acorn]

What do you mean "triggers"? It is an operator, like + or * but for booleans

[rich adder]

maybe they thought you need
if(true) return true
else
return false

[swift crag]

any binary operator can be used with two expressions

1 + 3
3 << 6
true || false
4 / 5f

nothing "triggers" the operators

[naive pawn]

(not to be confused with "bitwise" operators, which operate on the binary representation of integers)

[swift crag]

many of which are also binary!

as opposed to unary

-1
+3
!false
~5

or ternary

foo ? bar : baz

[naive pawn]

most operators are binary, notable exceptions are unary plus, minus, increment, decrement, logical not, bitwise not (unary) and conditional (ternary)

[swift crag]

the conditional operator is the only ternary operator I've ever seen, so it often gets called "ternary", yeah

[naive pawn]

(ts has a quaternary operator, that's fun to think about)

[swift crag]

it does? i've never heard of that

[naive pawn]

A extends B ? C : D for types, the extends is part of the syntax, there's no other conditions you can use

[swift crag]

ahh, I see

[timber tide]

I like the readability of binary/unary

if I want to try to compact my code as much as possible I'd just use python

[naive pawn]

pretty much all "normal" languages have them though?

[swift crag]

I use the conditional operator when I am just picking between two literals

val = Mathf.MoveTowards(val, activated ? 1 : 0, Time.deltaTime);

[polar acorn]

What is this power

[short hazel]

Pretty sure that's still a ternary, where the condition is itself a binary. Like this (a extends B) ? 1 : 2

C# equivalent would be a is B

[swift crag]

Not if it's part of the syntax

i.e. if you can't write anything other than A extends B ? C : D

if you can write A ? B : C in the same context, or A extends B extends QWERTY ? C : D, or something, then the operator isn't quaternary

I mean, I guess you could say that it's a ternary operator with a very very restrictive first part

But then you could also argue that A ? B : C is actually a binary operator with a very restrictive grammar for its right hand side

[naive pawn]

A extends B isn't a standalone clause, extends isn't its own syntax (at least, not in this way), and you can't use anything else as the condition for the "ternary"

astexplorer shows that A extends B ? C : D is a single construct with typescript or @typescript-eslint parsers

[rich adder]

unity moment..

[naive pawn]

it's a type operator

[swift crag]

Typescript has a pretty wild type system

[short hazel]

So there's this expression that looks like a ternary but is not, then the regular ternary expr ? a : b

[naive pawn]

yeah, that's for values

that exists in js

A extends B ? C : D is ts-specific, for conditional types

[swift crag]

https://www.typescriptlang.org/docs/handbook/2/conditional-types.html

[naive pawn]

ts doesn't really mingle types and values
there's just v as T/<T>v for casting, and typeof v to get its type (and typeof v can either be a value or a type depending on context)

[swift crag]

i've had this happen a few times

[rich adder]

it's so random, never had this happen on my version

[naive pawn]

i got it to happen consistently trying to import an mp3

[swift crag]

I love a ewent Ôn d esh R ndere

[rich adder]

luckily restart fixed it. Strange

[rich adder]

now that You mentioned it i did import mp3s into this project 🤔

recently

[naive pawn]

are you getting warnings about codecs

[rich adder]

if any were there they are gone now lol

[naive pawn]

ever tried to read warnings when 70% of the text is gone lol

(kidding, the text disappeared later)

[rich adder]

I forget I have Clear on Compile on and sometimes that fucks me over, especially fixing a bunch of errors now I need to reload the errors xD

[naive pawn]

also i noticed that it's not random parts of the string, it's random characters that disappear throughout, like the font for that character got nuked

[thorn iron]

Hello, I wish to know if this save load system from the following github is still pertinent, and can save/load MonoBehaviour, ScriptableObject, which contains custom classes as field and property.
https://github.com/NicolasPCouts/Save-and-Load-System

[misty pecan]

i have an object following the mouse, and i want it to do something when it touches another object, which has a "is trigger" collider on it, why does this not work?

private void OnTriggerEnter2D(Collider2D collision)
{
Debug.Log("touchpath");
}

[rich adder]

BinaryFormatter bf = new BinaryFormatter ();
FileStream fs = new FileStream (path, FileMode.Create);
😬

[rich adder]

does either object have a rigidbody

[misty pecan]

neither do

[rich adder]

well then there you go

how do expect a physics event to be called without a physics object present

[timid bridge]

At least one needs a rigidbody with kinematic/dynamic

[rich adder]

you might not even need the rigidbody, just a use a overlap

[eternal needle]

If you wish to know then
Although this is literally 4 scripts, you can make your own better one in like 10 minutes.

[misty pecan]

do i turn simulated off on the rigidbody? i dont want any physics on either of the objects

[rich adder]

you don't need it on both

and unchecking simulated makes physics not work..

[misty pecan]

if i uncheck simulated, can i still use OnTriggerEnter2D

[rich adder]

I just said it makes physics not work

if its not "simulated" how do you expect it to call anything

[misty pecan]

ah ok

[rich adder]

you can just use an overlap

you don't even need rigidbody

https://docs.unity3d.com/ScriptReference/Physics2D.OverlapCircle.html
but using the NonAllocating version

or use box. whatever

[misty pecan]

thanks it worked once i added a rigidbody

ill just stick with this i think its alot simpler to me atleast

[rich adder]

gotcha, it just may not be as precise if you move transfoms directly

[misty pecan]

ahh

[rich adder]

This is using BinaryFormatter, that alone is a sign for you not to use such an outdated way to do binary file. Microsoft has advised against using this formatter, new way uses BinaryWriter

[misty pecan]

radius.GetComponent<SpriteRenderer>().color = (255,0,0, 60);
how to set the colour to an rgba?

[rich adder]

you're asigning a tuple rn lol

[misty pecan]

how do i assign it a new colour?

[slender nymph]

also Color uses float values from 0 to 1 not 0 to 255. however if you want to use 0 to 255 you can use Color32 which has an implicit cast to Color

[rich adder]

well you need to pass an object of type Color32 or Color

if you want to manually type the values make a new object of type Color32
or you can make it a field and change it in the inspector

[misty pecan]

it tells me i cannot implicitly convert type (float,float,float,float) to unityengine.color

Color red = (1f, 0f, 0f, .5f);
radius.GetComponent<SpriteRenderer>().color = red;

[rich adder]

because you're doing a tuple right now

[misty pecan]

is this what you meant?

[languid spire]

do you know how to create a new Vector3 ?

[slender nymph]

correct, you need to call the constructor for the type you want

please go through the beginner c# courses pinned in this channel to learn how to do basic stuff like create an instance of an object

[final kestrel]

Hey All I am trying to add InventoryItems to my List once I spawn them. It works fine when spawning. When I despawn them on my UseItem and DropItem methods it kind of works for the first time when I empty my inventory. Removes them from the list. Then when I add more items and try to remove them from the list again. I get InvalidOperationException: Sequence contains more than one matching element it says.
https://hatebin.com/rbqfviogkq --> DespawnItem

https://hatebin.com/elmjucipqm --> SpawnItem

[misty pecan]

nevermind i figured it out all i had to do was write new Color

[final kestrel]

sequence it mentions is on the line with the linq

[slender nymph]

which you would understand how and why you need to do that if you bothered learning the fundamentals of the c# language

[rich adder]

very true

[misty pecan]

aight ill do that then

[slender nymph]

you do not need to use the SingleOrDefault method at all. you already have a reference to the object in the list, just pass it to the Remove method

but it does seem like you've added the item to the list more than one time based on the error message

[final kestrel]

I just passed in the itemInSlot as you said

it works but like.

[final kestrel]

Hmm. I do not have any way to prevent adding items more than once

[slender nymph]

well you need to figure out where you are even adding them more than once in the first place

[final kestrel]

I have the list in the inspector. I see them getting added and removed.

Well it works for sure

[slender nymph]

and do you see the items added more than one time?

[final kestrel]

No

[slender nymph]

well then you have duplicate item ids

those are the only two explanations for the error you received

[final kestrel]

becauuuse! I know because I have buttons that spawn items in my hotbar.

If there is items then It simply just wont add

now I have to figure a way to serialize a list of gameobjects in json

[slender nymph]

you don't. serialize the item data not the gameobjects themselves

[final kestrel]

I wanted to do this because I couldnt figure a way to serialize the Scriptable objects now dis T-T

[slender nymph]

create a class or struct that contains only the information absolutely necessary for the item. serialize that. then when you load that data you can spawn some prefab or something and pass that data to the spawned object to initialize itself with that data

[final kestrel]

Yes this starts to make sense now that I am struggling for like 3 days now

I watched some video where dude keeps the items in a database and then like gets them from there and puts them back into their places. I was going to try that

This whole save thing is out of this world. I was trying to make my character move a month ago

[timber tide]

keep your items simple for now. Make it so you only need to serialize an ID and slot

[final kestrel]

Well I do not hold any information on slot. I only spawn InventoryItem prefab on the slots transform.

InventoryItem basically has Item item scriptable object

Just initalizes itself on the given item.

[timber tide]

you dont need to serialize the prefab, you can just make a prefab table such that an id maps to the prefab

[final kestrel]

Like a database you say?

[timber tide]

pretty much but I usually think of databases are some remote server lol

[final kestrel]

Ah. My only database now holds Item scriptable objects now

[timber tide]

you can just make them a singleton in the scene that you initialize as you start the game

[final kestrel]

I understand that I have to break the stuff down into the most primitive type to serialize

but since I am so beginner. I cannot connect the dots haha

[timber tide]

prefab is already an amalgamation of stuff put together, so if you stick to id-ing that prefab as is, then the only thing you need to serialize is that

[final kestrel]

using UnityEngine;
[CreateAssetMenu(fileName = "Scriptable Object",menuName = "SO/Item")]
public class Item : ScriptableObject
{
   [field: SerializeField] public SerializableGuid Id {get;set;} = SerializableGuid.NewGuid();
   public Sprite image;
   
   
}

This is my Item object

I am using this custom made Guid class I got from a repo

using System;
using Systems.Persistence;
using UnityEngine;
using UnityEngine.UI;


public class InventoryItem : MonoBehaviour
{
    [HideInInspector] public Item item;
    
    [field: SerializeField] public SerializableGuid Id { get; set; } = SerializableGuid.NewGuid    ();
    public Image image;

    public void InitializeItem(Item newItem )
    {
        item = newItem;
        this.Id = newItem.Id;
        image.sprite = newItem.image;
        
    }

}

and this the inventoryItem sits on my prefab

[timber tide]

Alright, seems like you have the idea here

[austere gyro]

How to make delay in while?

[timber tide]

all you need to do is serialize that SO id and call some custom initialize constructor when you load those SOs back in, but if you were to also place them back into a specific slot of an inventory then you may need a specific struct to store that info too

[final kestrel]

I was thinking about getting the ids from a dictionary OnAfterDeserialize and like put them into my slots somehow

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

public class InventorySlot : MonoBehaviour
{
    public Image Image;

    public Color selectedColor, notSelectedColor;

    public void Select()
    {
        Image.color = selectedColor;
    }

    public void Deselect()
    {
        Image.color = notSelectedColor;
    }
    // Start is called before the first frame update
    void Start()
    {
        Deselect();
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

this sits on just a image prefab

[timber tide]

delaying a while loop requires coroutines usually, otherwise if you want to do it in update you would make a timer variable to check each update and then compare

I usually just have some script that goes through all my prefabs/SOs of a type and adds them to a list but then on start I add them to a dictionary

[final kestrel]

Do I need to do it on Start? I log the OnAfterDeserialize and it works pretty much everytime scene starts.

Wonder if its reliable

[austere gyro]

like yes? Task.Delay(3000).Wait();

[timber tide]

Usually you want to use unity's methods of waiting as Task may not be as synchronized as you want it.

I think there is a more Unity friendly Task method that was added recently

You also have these https://docs.unity3d.com/ScriptReference/MonoBehaviour.Invoke.html but as it states you may just want to use a coroutine

[austere gyro]

Thank You!

[timber tide]

but if you do want that frametime sync, usually you do want it to be comparing frametime each frame

[timber tide]

I resolve everything with my load screen and it seems to work fine. I usually have it referenced by my gamemanager too

[final kestrel]

Ah I see. I do not know about using singletons and game managers yet 😄

Gotta learn those some day

[timber tide]

it's just static classes with extra steps

benefits is that it exists on your scene and they have mono capabilities. Also you can clean them up if you wanted to and create a whole new instance.

[final kestrel]

Well that makes sense.

People are like noo singletons are bad, noo static classes shouldnt be used that much and shit

Gets me confused everytime whether I should study them or not

[timber tide]

Any manager can usually be a singleton; GamePools, Audio Systems, Particle Systems

Also, you can pretty much have a single singleton (the game manager) that references these managers

[swift crag]

I prefer singletons to a completely static class because:

• it's easier to "un-singleton" if you decide you need multiple instances later
• you can make a MonoBehaviour into a singleton, meaning you can easily serialize references to other assets

I have some singletons that load themselves from Resources on game start

Super useful. It doesn't matter which scene I enter my game from in the editor.

[final kestrel]

oo I saw that Resources looad thing while messing with the Scriptable objects as well. Could not understand what it does though

[swift crag]

https://docs.unity3d.com/ScriptReference/Resources.Load.html

It allows you to grab a reference to an asset by name.

[final kestrel]

by the name I set or? Like the asset's name

[swift crag]

Anything in a Resources folder is always included in the build. Normally, assets are only included if they're referenced by something else that's in the build (e.g. scenes)

Yes, by name

using UnityEngine;

public abstract class SingletonPrefab<T> : MonoBehaviour where T : SingletonPrefab<T>
{
    private static T _instance;

    public static bool Safe => _instance != null;
    public static T Instance
    {
        get
        {
            if (_instance == null)
            {
                _instance = Instantiate(Resources.Load<T>("SingletonPrefab/" + typeof(T).Name));
            }

            return _instance;
        }
    }
}

[timber tide]

I usually have a general load scene in all my games where I do load my managers in and bind them to "DontDestroyOnLoad" but the resource idea does sound useful as it is a pain to develop with lol

[swift crag]

this is in my GameController class

    [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
    static void OnLoad()
    {
        Instance.Initialize();
    }

[final kestrel]

Uhh lots to learn lots to learn

[timber tide]

I'd consider making yourself a GameManager singleton as it's even suggested by Unity itself

[verbal dome]

Not sure how Wait works but await Task.Delay(...) in an async method would work

[final kestrel]

Yess I will make sure to do that once I set this saving and loading

[swift crag]

You never delay in an Update method (or anything called by an Update method)

This freezes the game.

You can await a delay in an async method, or use coroutines to delay running something

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

[final kestrel]

Is it possible to instantiate prefabs from inside a list?

[swift crag]

Sure.

a List<T> can give you a T

so a List<MyComponent> can you give you a MyComponent, and you can instantiate that

[austere gyro]

I create it whis Invoke, but it it is activated only once

[final kestrel]

Ahh nice thanks

[swift crag]

Yes. Invoke runs a method once, after a delay.

https://docs.unity3d.com/ScriptReference/MonoBehaviour.Invoke.html

If you want to run a method many times, you could use InvokeRepeating

I would just write a coroutine that does it

IEnumerator SpawnStuff() {
  while (true) {
    LaunchProjectile();
    yield return new WaitForSeconds(2f);
  }
}

for a few reasons -- consider how you could do this

IEnumerator SpawnStuff(float startInterval, float endInterval, float intervalStep) {
  float delay = startInterval;
  while (true) {
    LaunchProjectile();
    yield return new WaitForSeconds(delay);
    delay = Mathf.MoveTowards(startInterval, endInterval, intervalStep);
  }
}

This lets you spawn things once per startInterval, speeding up a little bit each time until you reach endInterval

[austere gyro]

program start whis invoke method?

[swift crag]

no, you use StartCoroutine(SpawnStuff()); to start running the coroutine.

You could do that in your component's Start method

[austere gyro]

thank you

[austere gyro]

its problem whis project?

[swift crag]

You need to add using System.Collections; to the top of your script

The full name of the type is System.Collections.IEnumerator

Your IDE should be able to suggest this.

[austere gyro]

oh

[austere gyro]

i remove it

[austere gyro]

thank you

[indigo mirage]

i'm new to unity and im trying to follow a tutorial on how to make a flappy bird (GMTK) but when it comes to having a trigger activate, I am not sure why but the trigger isnt even activating at all

[languid spire]

https://unity.huh.how/physics-messages

[queen adder]

im following this tutorial but it doesnt give me the weapon options

[indigo mirage]

Thanks, this solved my issue

[verbal dome]

"The" weapon options?

[rich adder]

"the weapon options?"

thats probably Scriptable Objects

[queen adder]

so when he clicks create there is so section that says weapon like in the pick

[verbal dome]

I see Weapon as the first item in that menu

[queen adder]

thats a picture from the tutorail

[verbal dome]

How should we know that

[rich adder]

you either missed a step/video or it didn't compile code cause of error

[verbal dome]

Probably missing the CreateAssetMenu attribute

[quick pollen]

i completely forgot how you even do that

[rich adder]

show your GunData class

[zealous hatch]

RoomInst = Instantiate(RoomPrefabs[RoomPicker], new Vector3(1, 1, 1));
how come the new vector3 is underlined red. Compiler Error CS1503

[rich adder]

[CreateAssetMenu]

[quick pollen]

riight those things
I never used it before but still cool

to be fair I probably could for like projectiles

[rich adder]

Scriptable Objects are insanely powerful in unity

[quick pollen]

but I usually just copy paste pre-existing projectiles anyway soooo

[queen adder]

https://paste.ofcode.org/SrkrCFuiwHiWpjTCaDbXtU

[quick pollen]

I just never got around to using them, not yet at least

[rich adder]

yeah once you start getting used to them, they have many good usecases

ah yes

[rich adder]

You have compile errors as I suspected

anyway configure your IDE

also he has camera holder and i dont but i dont know how i would make that work

[rich adder]

You have clear syntax errors

[rich adder]

his is irrelevant right now, fix your code editor first

[warm raptor]

hello, so here is the code of the websocket serveur of my fps game. I want to make a void that is called like 20 time/s to send a message to each player to let them know the status of all the players of the game. But I can't make that void that is called 20/s in my class Lobby, I tried with a timer at the begining of the class Lobby, but it didn't work. Do you know how I can make this void ?

[queen adder]

i did this

do i do the debugging session

[rich adder]

this isn't the only steps

[queen adder]

yeah ive done everything else

[rich adder]

did you read the full page

[queen adder]

but also in the package manager they are locked

[rich adder]

yeah you gotta remove Visual Studio code editor

remove engineer package iirc

or click Unlock, you should be able to click Unlock on the page of package

[queen adder]

what happened

i click uninstall of engineering and now im on a weird page

[rich adder]

ok find the Visual Studio Editor one and make sure its installed and make sure the Visual Studio Code one is gone

[queen adder]

its back

when i unlock them it doesnt give me uninstall options

remove i mean

[rich adder]

is engineering package removed ?looks like its not . Screenshot it

[swift crag]

you have to remove the engineering feature first

you have not removed the engineering feature

[queen adder]

oh its back im sure i removed it

ok yeah thats sorted

[rich adder]

you are on unity 2021 arent you

[queen adder]

im not sure i just installed it off the website a few days ago

[rich adder]

how are you not sure, it literally tells you in the application titlebar lol

[queen adder]

oh its 2022

[rich adder]

ohh ok . so is vscode highlighting error now?

you can click regen project files first maybe in Unity

[rich adder]

click Show Error

see what it says, maybe you're missing .NET sdk somehow

[rich adder]

yerp

https://dotnet.microsoft.com/en-us/download

make sure you download the SDK

[queen adder]

setup failed

[swift crag]

can you be slightly more specific

[queen adder]

i think this is the right one

[rich adder]

you def do not have an ARM cpu

you need x64

[swift crag]

well, it's not

[queen adder]

yeah it failed too

im not sure

[swift crag]

and what is the error, then?

[queen adder]

the same

[swift crag]

screenshot it.

entire window

[swift crag]

You ran the same installer again.

Pay attention.

[queen adder]

oh mb

[rich adder]

yerp

[queen adder]

ok its installed but it still saying i need a net sdk

[swift crag]

restart your computer

[queen adder]

👍

bruh what

im still getting the same errors

[swift crag]

yes

this will not magically fix your code

the point is to make your IDE start working correctly

you still have to actually fix your code

[queen adder]

no i mean the sdk ones

[swift crag]

screenshot your entire VSCode window

[rich adder]

try regen project files in unity and open script again (open script from unity)

[swift crag]

Switch to the terminal

Then run this:

dotnet restore

Show me the result

[swift crag]

i'm not sure you actually installed anything

[queen adder]

im sure i did

it said to give feedback after it was finished

[swift crag]

here, run this:

dotnet --info

show me the output -- most importantly, the "Host: " section that tells you which version of .net is being run

[swift crag]

this did not include the part I'm looking for

expand the terminal area so you can see more at once

[swift crag]

it should produce something like this

that is an interesting thing to see

[swift crag]

This is, once again, not what I'm asking for

If dotnet --info didn't produce a Host: section then please just say that

[queen adder]

ye i was just wondering if it had anything to do with it

[rich adder]

what about dotnet --list-sdks

[queen adder]

i think this is what you mean

[rich adder]

you have the runtime but not sdk it seems

[swift crag]

Oh I see what's going on here

So you have .NET 7.0.12 on your $PATH

[swift crag]

But you installed the SDK for .NET 8

[queen adder]

ohh

[swift crag]

I haven't had to do this manually on Windows before so I'm unfamiliar with the process

[rich adder]

its not your fault, is windows being silly

[swift crag]

I just get the runtime from the .NET Install Tool extension

I guess the extension sees you have .NET installed already and isn't stepping in

(it's supposed to install .NET for you just for VSCode)

[swift crag]

I'm actually using .NET 8 in VSCode, but I have .NET 6 on my path

[swift crag]

I suspect it'll work if you go download the SDK for .NET 7

[queen adder]

👍

will i have to restart my pc again

[swift crag]

yeah

i need to go test this stuff out on my PC some more

[queen adder]

net 7.0 is out of support version do i still use it

[swift crag]

I'd just give it a try

I guess it'd make the most sense to remove .NET 7 entirely and install .NET 8

[rich adder]

Yes I'd run the cleanup tool
https://learn.microsoft.com/en-us/dotnet/core/additional-tools/uninstall-tool?tabs=windows

[balmy rivet]

Can i ask for help with my program here?

[rich adder]

is it a unity coding question?

[balmy rivet]

yes

[rich adder]

go for it

[balmy rivet]

Im new to unity and c# and im trying to learn how to configure solid objects and collision with player.
this is currently my code: https://pastebin.com/Uh5mkHmx
the problem in having is that when the player collides with the object on the SolidObjects layer. it can't move away xD

the player gets stuck

[verbal dome]

You could just add a collider to the object instead of checking for collision manually

[balmy rivet]

yea but how do i use that?

[verbal dome]

This approach is flawed anyway, as you noticed. If it goes into another object, you give it no chance to move away

[verbal dome]

You know how to add a collider to an object?

I assume yes since you are already checking for collider overlaps

[balmy rivet]

yea i do, but won't i still have the same problem?

[rich adder]

you're already moving the velocity on rigidbody, you don't need anything else other than solid colliders

[verbal dome]

No, the physics engine will separate the colliders and modify the velocity automatically

[dense root]

I am trying to use my button from a list of buttons, however when I try to actually call it to do something it throws an object reference null error
Button answerButton0 = this.answerButton[0].GetComponent<Button>();

The way it is declared at the header is as follows:
[SerializeField] private List<Text> answerButton;

Where did I go wrong?

[rich adder]

why not just make Button[]

[dense root]

Oh

Let me try that

[verbal dome]

Only answerButton here could throw a null reference exception

Or if you had a null item in the list

Maybe you have another instance of this component that is not properly set up?

[swift crag]

You should reference the thing you actually need, yes

and if you need both the Text component and the Button component, you should create a new component that has fields for both

[ivory bobcat]

Assuming you've actually referenced it from the inspector, the collection cannot be null and the elements cannot be null - the component can though, as you're likely referencing it as something other than Button.

[swift crag]

public class AnswerButton : MonoBehaviour {
  public Text text;
  public Button button;
}

now you can reference the AnswerButton and then retrieve the Text and Button components from it

[balmy rivet]

@verbal dome with this? rigidbody.collisionDetectionMode = CollisionDetectionMode2D.Continuous;

[verbal dome]

The main thing is to add a collider2d component to the player. Did you do that?

But yes, you might also want continuous collision detection

[balmy rivet]

ok yea

[verbal dome]

Unrelated to the problem though

[balmy rivet]

is the best thing just box collider?

thats what i have

[verbal dome]

Depends on your game. Boxes might get stuck easier as they have corners

Circle or capsule are alternatives

[balmy rivet]

oh yea i found out

much better xD

only problem now is that the world starts rotating when i hit it from an angle

[ashen ridge]

Huh

[queen adder]

im still getting the same errors

[swift crag]

did you completely uninstall .NET and then install the .NET 7 SDK?

[ashen ridge]

How? lol

[balmy rivet]

no idea lmao, i got scared

its really just the player that rotates, but the camera is attached to the player so the world rotates aswell lmao

[ashen ridge]

Ok
Seems easy to fix, can you send a quick video

[queen adder]

yes

[balmy rivet]

fixed it with freezeRotation, so we're good

[swift crag]

show me the result of running dotnet --info

[summer stump]

Pretty common with rigidbodies. Angular velocity

[queen adder]

i swear i have tried it like 3 times

[swift crag]

and let me see the Host: section

[queen adder]

thats the whole thing

[swift crag]

scroll up

[queen adder]

i downloaded x64 should i try x86

[swift crag]

no, you should not

[swift crag]

this appearse to be the same version of .NET that you started with

what did you actually do to uninstall and reinstall it?

[queen adder]

i installed the cleanup and activated it

[swift crag]

switch to the Output tab and then switch to the C# option in the dropdown on the right side. I want to see which .NET it's actually using

[dense root]

Got it working, thank you so much all

[swift crag]

this is what I see, for example

[swift crag]

copy the entire output and share it with a paste site like https://gdl.space

[queen adder]

https://gdl.space/koqiresopa.cpp

[swift crag]

this looks wrong

[swift crag]

screenshot the entire output window

[swift crag]

the entire window, including the dropdown at the top

you are probably looking at the wrong output

[swift crag]

that is not "C#"

that is "C# LSP Trace Logs"

pick C# and then share the entire output log

[queen adder]

oh mb

https://gdl.space/toritocila.coffeescript

[swift crag]

The architecture of the .NET runtime (x86) does not match the architecture of the extension (x64).

hm, interesting

But looking at the rest of the log, that looks fine

[swift crag]

..did this mean the same errors from unity?

[queen adder]

nah i mean the .net errors

[swift crag]

because the C# output looks fine

[queen adder]

i got this too

[swift crag]

but I see that the project failed to activate

[queen adder]

well the main thing i was trying to do was this

[swift crag]

google suggests this is an error you'd see in visual studio

hm, consider this:

close VSCode

go to the root of your project and delete the .csproj files

[queen adder]

the what

[swift crag]

as well as the .sln file

[swift crag]

do you know what a file extension is

[queen adder]

yeah

i mean where is it located

[swift crag]

there will be files in your project root (so, the folder that has your Assets folder in it) with .csproj extensions

it's the folder you created your unity project in

one will be named Assembly-CSharp.csproj, for reference

[late burrow]

and again that

[swift crag]

delete the .csproj files and the .sln file, which will be named after your project

[late burrow]

i made 2d array how i make it not null inside entries

[swift crag]

then, in unity, regenerate the project files from the External Tools window

[queen adder]

which bit

[verbal dome]

"inside entries"?

[late burrow]

everything inside array

also i meant array inside array not 2d array

[swift crag]

both of those files at the bottom

Assembly-CSharp and "My project (1).sln"

[verbal dome]

Put some effort into explaining your problem for once god damnit

[swift crag]

i see that windows is hiding the file extensions

[queen adder]

do i restart unity

[verbal dome]

If the array has null entries then you haven't assigned anything to them

[swift crag]

No, but you need to regenerate project files from the External Tools menu after doing this

Then you need to double click a script asset to open VSCode

[queen adder]

bro im getting the same things

[swift crag]

you appear to have something very weird going on, since i saw both 32-bit and 64-bit .NET installs from your screenshots

(x86 and x64, respectively)

[queen adder]

is it possible to skip this or is it neccessary

im meant to create asset menu

but if i cant fix this error im stuck out of the game

[verbal dome]

If it's an array of arrays, then it's going to be filled with nulls by default. Array is a reference type and the default is null

[swift crag]

it would be ideal to have a working code editor

i have no idea what's going on with your .NET install(s) though

you could also just try Visual Studio

i'm pretty sure it bundles its own .net runtime and SDK

[queen adder]

i think ill try it tommrow its getting late now

[tall orbit]

alguien habla español???

[ancient seal]

Where’s the best place to learn coding?

[young lava]

Hi! I feel like this is an easy solution, but I'm not actually seeing much online regarding my problem. So pretty much I am working on a projectile targeting system and I want to check if the projectile is actually landing in the current room the player is in. The issue I am running into is the logic for detecting a collider. My room pretty much has a roomCollider which is a tilemapCollider2D + compositeCollider2D, which encompasses the entire room. I've tried methods such as Physics2D.OverlapPointAll and OverlapPoint as well, but for some reason they are not detecting any colliders (even though the position is very clear inside the collider). Does anyone know what the issue is?

[vale bronze]

How do I stop my Rigidbody Controller from getting stuck on walls when moving? I've seen multiple sources online saying to add a physics material with 0 friction, however this doesn't do anything. If the player jumps, lands on the side of the wall, and keeps pressing forward, they just get stuck there and stop falling until they stop moving. Any ideas?

[verbal dome]

Show the code that you tried with OverlapPointAll

It should work for this usecase

[verbal dome]

Rigidbody controllers are not easy to make. To me it sounds like you are directly modifying the velocity, which would make it seem stuck on the wall when walking

I would make the velocity change weaker or nonexistent when you are on a steep wall

[young lava]

private bool IsPositionInsideTilemap(Vector3 position)
    {
        if (dungeonManager != null)
        {
            // Get the current room from dungeonManager
            GameObject currentRoom = dungeonManager.ReturnCurrentRoom();
            if (currentRoom != null)
            {
                Transform roomColliderTransform = FindChildRecursive(currentRoom.transform, "RoomCollider");
                if (roomColliderTransform != null)
                {
                    // Find the TilemapCollider2D within the current room
                    TilemapCollider2D tilemapCollider = roomColliderTransform.GetComponent<TilemapCollider2D>();
                    if (tilemapCollider != null)
                    {
                        // Ensure the position is on the same plane as the 2D physics
                        Vector2 point = new Vector2(position.x, position.y);

                        bool isInside = tilemapCollider.OverlapPoint(point);

                        Debug.Log("tilemapCollider.OverlapPoint(point): " + isInside);
                        Debug.Log("POSITION: " + point);
                        return isInside;
                    }
                    else
                    {
                        Debug.LogError("TilemapCollider2D not found in the current room.");
                        return false;
                    }
                }
                else
                {
                    return false;
                }
            }
            else
            {
                Debug.LogError("Current room is null.");
                return false;
            }
        }
        else
        {
            Debug.LogError("DungeonManager is null.");
            return false;
        }
    }

The debug statements in the inner most if statement chain are printing false so I know it is from lack of detecting colliders.

I've also simplified it to just printing every collider hit in OverlapPointAll and no colliders are found

[verbal dome]

Hmm not sure, could you put that in a paste site, its really hard to read on mobile

And might also wanna try asking tomorrow when most people arent sleeping

[young lava]

https://pastecode.io/s/ks6vf78p

[verbal dome]

Btw, there also seems to be Collider2D.OverlapPoint if you want to check if the point is on a specific collider

[swift crag]

that's being used here

I don't see OverlapPointAll anywhere, though, which is confusing me a bit

[young lava]

Oh I can send you my overlap point all version

[swift crag]

The debug statements in the inner most if statement chain are printing false so I know it is from lack of detecting colliders.

So it's not logging TilemapCollider2D not found in the current room, correct?

[young lava]

correct

[verbal dome]

Oh woops

They said Physics2D.OverlapPoint in the first question so I just assumed

[swift crag]

Make sure you don't have multiple tilemap colliders (one of which would presumably be completely empty)

you should also check if your tilemap collider actually has any solid spaces

[young lava]

I do have multiple tilemap colliders but in the if statement chain I loop through very specific gameObjects to make sure I get the correct one located on the right gameObject. By solid space do you mean like physics space or if the collider is present, because the collider is there.

Also here is my other snippet of code, I just put this on an empty gameobject over my room collider and it is not printing anything.

https://pastecode.io/s/tsicew49

[swift crag]

as in, is the tile collider actually solid anywhere?

are there any solid tiles?

[young lava]

Yes there are solid tiles, though I do have the tilemap renderer turned off but if I turn the renderer back on, then a bunch of tiles appear.

[swift crag]

you can sanity check this by manually adding a 2D collider in the spot you're doing the query at

the code should find that collider

[young lava]

yep I added a 2d box collider to to same spot the testing script is located on and it prints it using OverlapPointAll

So it seems like it is just something wonky with the tilemap collider/composite collider right?

[swift crag]

can you prove that the tilemap collider is actually solid at that point?

like, by bumping into it with the player?

Tiles have to have a physics shape configured for them

[young lava]

Oh sorry, I might have misunderstood by solid, do you mean physically interact? The collider is an isTrigger, the player can't actually physically interact with the collider, it's pretty much used to check if the player is in the room or not for other scripts.

[swift crag]

Oh, if it's a trigger collider, then you have to make sure that you've turned on "Queries Hit Triggers" for OverlapPointAll to detect anything

I'd still expect the OverlapPoint method to have worked

[young lava]

Ya I just turned on isTrigger for the test collider we added and it works fine too xD confusion

[swift crag]

you could make it a non-trigger and then see if the player actually bumps into anything

I'm currently doubting that your tilemap collider is actually covering any space at all right now

[young lava]

Okay, I'll try that. Does overlapPointAll require collisions between the two layers of the script and the collider to be turned on? I searched that up and sources say that doesn't matter.

[swift crag]

OverlapPointAll doesn't care about the layer your component happens to be on

[young lava]

Okay so I turn off is trigger and enabled collisions between playerPhysics and the collider layer and yes the player is running into the collider and interacting with it.

[swift crag]

Now, disable the tilemap collider

Do the collisions stop?

[young lava]

yes

[swift crag]

Very odd.

here's one thing: try logging the bounds property of the tilemap collider

see what space it covers

I would also make sure you're getting the correct collider by doing this:

Debug.Log("Using this collider.", collider);

clicking on that log message will take you to the object referenced by collider

[young lava]

Okay I positive it is a composite collider issue

I just turned the test collider into a box + composite collider and it is no longer detecting

[swift crag]

ah, i completely glossed over that

Did you set the composite collider to 'outlines' mode?

if so, it doesn't have an interior -- it's strictly an edge collider

[young lava]

ah yes.

thank you

very much

this has been annoying XD

[swift crag]

no prob :p

[timid hinge]

i dont know what can i do to solve it

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

public class elementalStaffSpawner : WeaponSpawner
{
protected override IEnumerator StartAttack()
{
EnemySpawner enemySpawner = EnemySpawner.GetInstance();

    while (true)
    {
        UpdateAttackPower();
        UpdateAttackSpeed();

        if(enemySpawner.GetListCount() > 0)
            SpawnWeapon(Direction.Right);

        yield return new WaitForSeconds(0.1f);

        if (GetLevel() >= 2 && enemySpawner.GetListCount() > 0)
            SpawnWeapon(Direction.Right);

        yield return new WaitForSeconds(0.1f);

        if (GetLevel() >= 3 && enemySpawner.GetListCount() > 0)
            SpawnWeapon(Direction.Right);

        yield return new WaitForSeconds(0.1f);

        if (GetLevel() >= 5 && enemySpawner.GetListCount() > 0)
            SpawnWeapon(Direction.Right);

        yield return new WaitForSeconds(0.1f);

        if (GetLevel() >= 7 && enemySpawner.GetListCount() > 0)
            SpawnWeapon(Direction.Right);

        yield return new WaitForSeconds(GetAttackSpeed());
    }
}

}

[vale bronze]

thanks for the suggestion. I got a basic system for this working using some raycasting but I now realize how difficult it's going to be to program with each edge case in mind. instead, is there anyway to be able to have a character controller also work with physics?

[vale bronze]

it looks like, for the second error, you have two methods (functions) with the same name StartAttack. You probably want to rename one of them if they do different things.

for the first error, it may be that you have two classes called elementalStaffSpawner. again, renaming one of the classes by renaming the file and the class name should fix it. I may be wrong about this error but I'm pretty sure it's this

[timid hinge]

thanks solved already

but this one

its on 114 line what can i do ?

[vale bronze]

All of those mean that the respective variable is null (doesn't exist).

[eternal needle]

That is some code

Null errors are always the same, there is a shitton that can be null there

[timid hinge]

but how can i solve it?

[vale bronze]

so I guess the if statement part is returning null? I would need more code to understand. can you explain what the if statment is checking?

[timid hinge]

is it something on inspector or is in the code

[vale bronze]

I think it'd be in the code unless ItemAssets is something in the inspector

[eternal needle]

You need to debug and find that out for yourself. There are so many parts there that can be null

[timid hinge]

item assets its all good

[rocky canyon]

u got 2 errors about the object pooler and 1 about ur inventory..

in those scripts / functions use null checks b4 u run any code on stuff

but the real solution is to fix those in the first place.. if ur trying to use something make sure its assigned or referenced somehow

[summer stump]

You have been told how to share code before...

None of the messages you just sent are the right way

[violet glacier]

What's the best way to pause certain objects/ui/animation while keeping some objects moving?

[rich adder]

make script to pause those specific objects

[summer stump]

https://unity.huh.how/references

A singleton is usually a good choice for what nav said.
Could have multiple pause states or events for the different sets of of objects you want to pause if it is complex

[versed light]

when is transform.hasChanged ever false i have a component where i never change the transform data yet hasChanged is always returning true in the update method. even when set to static its still returning true

[north kiln]

Have you read the docs? Are you setting it to false?

[versed light]

no ? wouldnt they set it to false on the next frame?

docs dont really say if they set it to false or not, does it just stay true until we set it to false?

[north kiln]

https://github.com/Developer-Notes-Extension/Unity-Notes/discussions/532#discussioncomment-5021202

[versed light]

ah wow

[final plover]

Not sure exactly what channel to post this in but im having a weird issue. As seen in the editor the ground is below the player. The player is also colliding with the ground. For some reason the ground is not showing in game. The player is on layer 2, the ground is layer 3. The camera should be showing it and if you go to any ground instantiations that are closer to x=0 then they are visible. I cant quite find where it cuts off.

[spare mountain]

what z-position is your ground at

[final plover]

Its at z=0

[spare mountain]

and your camera?

[final plover]

about 3

[slender nymph]

your ground is behind the camera

[spare mountain]

@final plover ^^

[final plover]

ah thx

[slender nymph]

you typically want to stick your camera at -10 so that doesn't happen

[jaunty bone]

y'all

im lowkey understanding it

like ngl this coding shit kinda easy

(prob gonna regret that alter on)

[lethal smelt]

is this gd script?

[jaunty bone]

walalhi

no

its c#

[spare mountain]

this isn't unity

[willow scroll]

This is C#

[spare mountain]

not unity tho

[willow scroll]

But this wasn't a question

[spare mountain]

then it breaks both rules

[willow scroll]

Then you should have said "this isn't a question "

[spare mountain]

both apply, it doesn't matter which one I say

[lethal smelt]

[elder osprey]

I have a script that makes objects float at an offset in front of the player. I am using a lerp to make the object position smoothly, but I'm experiencing an issue where the objects lag behind and stutter frequently on lower end PC's. Here is my script: https://hastebin.com/share/owepohimix.csharp. Video recorded on M1 Macbook Air: https://streamable.com/3ibrw8

[eternal needle]

whats the point of that whole duration = frameRate/(60 * 1000000) these are all magic numbers.
You are also starting a coroutine every single frame, so its gonna be "fighting" over where to set the position when multiple are running. In this case i suspect you probably have 2 running at all times since these magic numbers are so small that elapsedTime will quickly be greater than duration

[elder osprey]

Huh, disabling the lerp changes nothing, so you are right with elapsedTime being greater instantly. How can I make it follow the player without stuttering with the frame rate?

[eternal needle]

you dont need the framerate at all, im not sure how you even decided on such formula. you're already using update, just MoveTowards every frame with deltaTime as your difference in time.

[elder osprey]

you mean like this? cs void MoveTo(Vector3 destination) { transform.position = Vector3.MoveTowards(transform.position, destination, Time.deltaTime * 10); }

[stiff briar]

guys
what is deltatime
cant find it on wiki

[elder osprey]

https://youtu.be/yGhfUcPjXuE?si=6Ij9mzFq28J7_fVL

[faint sluice]

You shouldn't wiki that, look up official documents as they are very nicely documented

Also this video above ^

[eternal needle]

sure but no need for the magic numbers still, serialize a number for that 10 so you can adjust the speed. Also this may still fall behind so you can adjust the speed based on how far it is

[void thicket]

"delta" is commonly used term for "difference between two values"

[stiff briar]

thx!

[void thicket]

In this case it's time difference between current and previous frame

[stiff briar]

oohhh

i thought its second and frame

[void thicket]

It's unit is in seconds for Unity

But it's not tied to concept of dt

[stiff briar]

btw imma ask a basic question maybe someone who got enough time will answer it
if i were to make a running mechanic in a 3d game
can i use like... public class walkspeed... and public class runspeed...
then use something like, if (shift get pressed) then walkspeed == runspeed?
(i cant open unity right now so i cant experiment)

[elder osprey]

Yeah, it falls behind a lot, how could I adjust the speed? It lags behind a bit when it starts far away: https://streamable.com/4jew6t

[faint sluice]

1. those would be variables not classes
2. walkspeed = runspeed for assigning values, == means comparison
3. I guess? Depends on how you use it

[elder osprey]

1. Have a variable for speed
2. Have two serialized variables for walkSpeed and sprintSpeed
3. Set speed to walkSpeed by default and to sprintSpeed when sprinting

[ruby python]

Mornin' all,

In my projects I like to generate levels randomly (cause I suck at actual level design. lol.) and I've always used the same/similar method.

Basically I just instantiate a bunch of objects in each Method one after the other, if this was a continuous thing the performance would tank, but as it only happens on level start I figured there wouldn't be a performance hit.

https://hastebin.com/share/nozoferegu.csharp

This is my current level generation, it's pretty simple at the moment, but I will be adding more 'layers' (ground rocks, bushes, trees etc. to fill out the level), but I was wondering if there was a better/more efficient way to do it?

[stiff briar]

ahh so it could work then? aight imma find the working script for it

[faint sluice]

Also I would make third variable called current speed

And assign value of walk speed or running speed to current speed depending on what's being used

And move my object using currentspeed

[eternal needle]

well you can adjust it, if you store it in a variable. its just multiplication so im not really sure what you're asking

[stiff briar]

so if shift is pressed then current speed is equal to runspeed and if not then its equal to walk speed?

[faint sluice]

Yep

[stiff briar]

ok thx

[faint sluice]

You can use object pools if you're worried about performance issues

[ruby python]

Yeah I'm using pools for everything else that gets spawned throughout the game, but it wouldn't be beneficial when initially generating the level as none of the 'map' items get removed etc.

[faint sluice]

You're instantiating maps randomly, all using same items?

[faint sluice]

Also object pooling is never about "removing" items , I'm concerned

[elder osprey]

So, increase the speed variable based on how far the object is from the target position?

[eternal needle]

if you want to, yes

[ruby python]

Huh? not sure what you mean by this. Why concerned? What I mean by removing is that the map items never get removed after they've spawned at the level start, so there's no need to pool them (instantiating directly, or instantiating them into a pool is the same thing). A pool just lets you activate/deactivate the object(s) instead of destroying and instantiating over and over.

[charred condor]

Is there a way or some type of algorithm or way to center the player in the camera's viewport by only moving the camera on the global X & Z axis (without changing the camera's rotation or height)?

[rich adder]

cinemachine

[charred condor]

Ohhh. Never got into cinemachine but I guess it's time. 🙂

Thanks @rich adder

[abstract finch]

Is something like this possible? An abstract class thats able to do a coroutine?

[faint sluice]

Yes but you can premake the pools instead of instantiating at runtime

Say you need 500 trees to be randomly spawned in the game, premake the pool of 500 trees and spawn them at runtime

[rich adder]

you didn't make it virtual though

how can you override

[ruby python]

huh? Okay, I'm massively confused now, because building the pool still needs to instantiate the 500 objects (in your example) at runtime.

[faint sluice]

Also make it abstract ienumerator if it's going to be implemented in every inherited child

[abstract finch]

Sorry I'm not sure what it means, so I need to make the handlestate coroutine public virtual override?

[faint sluice]

Not really no. You create the objects in scene beforehand and save them in the pool.
An asset that let's you do this effortlessly is LeanPool. You can check it out as well

[rich adder]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/virtual
Probably should readup on the thing you are using before you use it incorrectly

[abstract finch]

ok

[faint sluice]

Remove virtual from the inherited class

[abstract finch]

yea I got it now

[faint sluice]

Virtual only needs to be added in parent class, but it already has abstract so it's no longer necessary

[abstract finch]

Got it thanks

[rich adder]

yes abstract becomes similiar to Interface

[abstract finch]

I've only worked with interfaces in place of these before but i figure this is a better approach for serialization

[tepid steeple]

Guys i have a problem i finally completed project but not work online in apk. When i test the project in pc its works done and easily auto-find server and connect. In mobile cant find the host server how can i fix this ?

[rich adder]

the difference here is inheritance vs composing

you can only inherit one, but you can implement many interfaces

[abstract finch]

thats true actually

[rich adder]

no one knows anything about the setup so this is unanswerable, also networking questions go in #archived-networking

[abstract finch]

what i struggle with when doing interfaces is serialization, lets say that i have IAction and IState. IAction also has IState. IAction like Attack1
In order to identify them at start I have to do GetComponentsInChildren<IState>, with this I can just drag it to the inspector

but yeah it's something I should think about later

[rich adder]

I guess, otherwise normally they would Register themselves

my save sytsem, if I have object that implements ISaveable, I'm not gonna go look for that every time or maybe you might miss spawned ones.
The ISaveable takes care of registering itself to the main Saving Script that needs ISaveables to store

[charred condor]

void SmoothCenterOnPlayer()
    {
        if (isLockedOnPlayer)
        {
            centerTimer += Time.deltaTime;
            float t = centerTimer / centerDuration;

            // Get the ray from the camera to the center of the viewport
            Ray ray = Camera.main.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0f));
            Plane groundPlane = new Plane(Vector3.up, Vector3.zero);

            if (groundPlane.Raycast(ray, out float enter))
            {
                // Get the world position of the viewport center
                Vector3 currentViewportCenter = ray.GetPoint(enter);

                // Calculate the target position to move the camera
                Vector3 targetPosition = transform.position + (playerTransform.position - currentViewportCenter);

                // Lerp the camera's position to smoothly move it
                transform.position = Vector3.Lerp(transform.position, new Vector3(targetPosition.x, transform.position.y, targetPosition.z), t);
            }
        }
    }

Found a solution online to do it programmatically. But still going to check out cinemachine.

[eternal needle]

if they are spawning the objects at the start of the scene, pooling does literally nothing here

[faint sluice]

Instantiating at start would still be slower than having them preloaded and just enabling no?

[charred spoke]

The scene needs to instantiate them when it loads as well

[faint sluice]

Hmmm tru nvm then

[eternal needle]

profile to see whats really taking the longest. unfortunately its likely gonna be Instantiate, which you cant do anything about unless you can spawn less objects. Make a loading screen and problem solved 🪄

[eternal needle]

i think you have a misunderstanding at what pooling is, you dont magically just get the items. You have to actually instantiate it at some point. Whether thats at the start of the game, or the start of a scene doesnt matter

it would just be moving the lag from one area to another

[faint sluice]

Ye ye I forgot scenes instantiate all object when loading

[eternal needle]

thats somewhat unrelated, because thatd imply the prefabs were in the scene manually placed. A pool still could place objects in DDOL

the only use case i guess would be if they wanted to reuse objects between maps, not sure how much that'd really matter though

[carmine narwhal]

why does this happend ? first picture looks right but when i do a prefab from the origin cube the transform dissapears like this and now i cant add anything to the transform field

[languid spire]

transform field?
you have the prefab selected not the gameObject in the hierarchy

also not a code question

[tepid steeple]

@languid spire

whats up

Can you help me on networking ?

In PC host and client perfectly working but in mobile not find the server.

[languid spire]

#📖┃code-of-conduct Do NOT ping people into your conversation.
And no, I generally do not help people with Networking problems

[tepid steeple]

[carmine narwhal]

where should i ask this questions?

[languid spire]

you have asked it here and I have told you the answer

[ruby python]

Oh yeah there will be a loading screen. The question wasn't so much about perfomance tbh, as all this happens on level start etc. and only happens once and nothing in the map gets destroyed. Was just a curiousity as to whether there was a better way than just going through each 'layer' of object and instantiating like I've got coded is all.

[carmine narwhal]

not really, cause you missunderstood me, so i asked where to ask these questions since you said it was in the wrong chat. i thought i had done something wrong with the code.

[languid spire]

ok then #💻┃unity-talk and give a more detailed explanation of what your problem is

[eternal needle]

i dont see anything wrong with that specifically. if you want to spawn some of everything, youll need to go through each kind of object you want to spawn.

[ruby python]

Yeah, that's what I usually do, create a method for each item type and then just call them in turn. It's very methodical etc. and it does work great, just looking at it and it just seems a little inelegant if that makes sense? And tbh, pretty much everytime I post code somebody always seems to find something I'm doing wrong. lol. So was just a curiosity more than anything

[eternal needle]

You could define what spawns via scriptable objects which would move some of the work to editor instead. i dont really remember what your code was but this would turn it into a shorter code solution with the same outcome. Would be more friendly for others to work with as well, and support adding more items without changing the code

[ruby python]

Aaah, that's interesting. Although I'm still struggling a bit on how to use SO's properly, but that's definitely something I could look into.

And would be a big help based on what I'm planning on doing (different maps/levels set in different locations/time periods etc)

Just thinking out load. But I'm thinking Scriptable object of type 'Spawnable Object' add them all into an array ((SpawnableObject[])), then in my map generation do a foreach SpawnableObject and spawn that way?

[eternal needle]

at first I didnt really understand the use for SO too. i think the intended use case is so simple that once you get it, its almost like "is that it?"

in your case, you literally just need to add fields relevant to whats spawning, like GameObject for the prefab, an amount to spawn, then possibly values for how it should rotate or scale etc

[ruby python]

Yeah I'm using an SO for my enemy stats atm (speed/damage/health), really simple, but got it working, so I'm getting there. lol.)

[eternal needle]

id probably start with this, and add whatever else you know you need

public class SpawnableObjectSO : ScriptableObject
{
    public GameObject prefab;
    public float minSpawn; 
    public float maxSpawn; 
    public Vector3 maxDeltaScale; // if you want random scale
    public Quaternion maxDeltaRotation; // for random rotation
}

though you might need to add more like information of how it should spawn in relation to the ground, should it spawn inside (like a rock) or exactly ontop like a flower

[ruby python]

Yeah. All the things generally spawn the same (except obviously the two things I included in my example, they spawn in a circle lol.). But everything else is randomly placed/rotated/scaled, so yeah an SO make perfect sense with just one method to spawn them in based on the SO values.

[waxen cypress]

Anyone know how to fix this?

[languid spire]

Ok, that looks like a Unity bug, restarting Unity should clear it

[waxen cypress]

Alright thanks!

Saving will still work yeah?

[languid spire]

yes

[waxen cypress]

Alright Thanks.

[ruby python]

Okay, so I think I have my map generation sorted using an SO (I haven't made the items/SO objects yet, but in my head this should work fine, just looking for an extra set of eyes to see if I've understood it all correctly if that's okay. 🙂

SO Setup.

[CreateAssetMenu(menuName = "Ground Items/Ground Item")]
public class GroundItem : ScriptableObject
{
    public string groundItemName;
    public GameObject[] groundItemPrefabs;
    public Transform groundItemParent;
    public float groundItemCount;
    public float groundItemMaxRadius;
    public float groundItemMinScale;
    public float groundItemMaxScale;
}

Implementation

    [Header("Ground Items")]
    [SerializeField] GroundItem[] groundItemSOs;
    void SpawnGroundItems()
    {
        for (int gSO = 0; gSO < groundItemSOs.Length; gSO++)
        {
            for (int i = 0; i < groundItemSOs[i].groundItemPrefabs.Length; i++)
            {
                //Do ground item spawny things
                float randomRadius = Random.Range(0, groundItemSOs[i].groundItemMaxRadius);
                angle = Random.Range(0, 359);
                Vector3 pos = GameManager.Instance.HelperManager.RandomCircle(groundItemSOs[i].groundItemParent.position, randomRadius, angle);
                Quaternion rot = Quaternion.Euler(0, Random.Range(0,359), 0);
                GameObject newGroundObject = Instantiate(groundItemSOs[i].groundItemPrefabs[Random.Range(0, groundItemSOs[i].groundItemPrefabs.Length)], pos, rot);
                newGroundObject.name = groundItemSOs[i].groundItemName;
                newGroundObject.transform.parent = groundItemSOs[i].groundItemParent;

            }
        }
    }

[languid spire]

mistake here I believe

for (int i = 0; i < groundItemSOs[i].groundItemPrefabs.Length; i++)

[ruby python]

Ah yeah, the groundItemSOs[i] should be gSO (on all). oopsy. lol.

[languid spire]

I would do

for (int gSO = 0; gSO < groundItemSOs.Length; gSO++)
        {
            var array = groundItemSOs[gSo];
            for (int i = 0; i < array.groundItemPrefabs.Length; i++)
            {
                var item = array.groundItemPrefabs[i];

then use item thereafter. it makes the code much more readable

[ruby python]

Right I got you.

Thank you 🙂

hello guys I have a pickup and drop system for guns in my fps game with works fine when the animator is disabled on the gun
But when the animator is enabled, the gun teleports to the world origin

here is the code

[willow scroll]

Because one of your animations assigns its position

[short hazel]

Yep that's an animator issue

[willow scroll]

If you want your animation to work properly, you have to create an empty GameObject inside of your gun and put your animator on it

Note that everything associated with displaying the gun should be put on that object too

E.g. SpriteRenderer etc.

[short hazel]

You have keyframed the gun's position at some point. When the animation plays, the animator sets that position back, moving the gun itself elsewhere (here, to origin)

Those are 2 problems, solve them one at a time. Objects colliding with the same name and dividing.
One is just looking up collisions in Unity and 1 is just instantiating another object of the same type.

[austere gyro]

I can't find documentation about colliding object

[fossil drum]

🤔

[austere gyro]

lol i seek if touch

[short hazel]

You should also avoid doing logic on object names, it has its flaws (names change, especially when you copy objects). Prefer detecting a script with the "name" as a variable inside of it

[fossil drum]

And you don't think the documentation of collisions explain the if touch thing?

[austere gyro]

i found it

Syntax error, 'word' expected after "its"

Yes that is valid. You can give it any name you want, like other variables

[austere gyro]

Im sorry

In this specific example, other will contain the other collider this object interacted with

Though to actually detect collisions you might want to use OnCollisionEnter2D(Collision2D other) instead, with the proper collider setup on your game objects

i have no clue what im doing here

[short hazel]

It starts off well, but you cannot use Resources.Load() to retrieve elements that are outside your project, and you're not using the correct path format

https://docs.unity3d.com/ScriptReference/Resources.Load.html

Also AddComponent() returns the component it created, so you can do

SpriteRenderer BGsprite = SliderBG.AddComponent<SpriteRenderer>();

and spare yourself a GetComponent call

(or scrap 90% of this code and use a prefab instead)

Yes, you should absolutely just make this a prefab

What are possible reasons why my class cannot see my other classes type/existence?

even when I try to resolve the redline, it just wants to generate that other class. But that other class already exists

I cant pass CombatTrackerCommandPanel in directly instead of EditorWindow because it can't see that either

my real xy problem here is how do I force it to see it

it can see the generated one, why cant it see my one?

and why do these two scripts not conflict and complete despite having identical name and no namespace?

what I am actually trying to do is make a generic draw method for editor scripting window stuff and I need to reference but isolate the gui draw stuff from the main build stuff

[late burrow]

how i get dictionary by index

[swift crag]

one of those is in an Editor folder

anything in an Editor folder is automatically put into the Assembly-CSharp-Editor assembly, which is not referenced by the Assembly-CSharp assembly

unless you override that behavior with assembly definitions

[orchid trout]

Oh so the fact that its editor code blocks it off 🤔

[swift crag]

Right.

[orchid trout]

I know it has to be in editor because its editor code and breaks the build, I didnt realize other code cannot then see any of that

[swift crag]

If other non-editor code could see the editor-only code, then it would depend on being able to use stuff from the UnityEditor namespace

[scarlet tiger]

the alternative is to use preprocessor directives with UNITY_EDITOR to block the code from being in the build

so you can remove the editor folder and wrap the whole class

[swift crag]

yeah -- if you want part of a class to still exist in the build, then that's the way to go

[late burrow]

also does dictionary even keeps order i inserted stuff in it

[scarlet tiger]

i don't believe it does, i think there might be an OrderedDictionary if you need that

Breakpoints are in code

where can i check in the inspector or is something on the code

In the code directly, by debugging

You'd want to break that line up into multiple to ease out the process, because it's pretty huge right now

[timid hinge]

i can send my project man

[spare mountain]

💀

[summer stump]

It's just above

[short hazel]

Learn how to debug, it's easy

[summer stump]

Fuck no

[timid hinge]

ok man

[spare mountain]

ah nvm

[summer stump]

Just add the debugs we said.

TRY

[timid hinge]

what debugs?

[summer stump]

Debug.Log on all the things that could be null

[short hazel]

1. http://unity.huh.how/debugging
2. https://docs.microsoft.com/en-us/visualstudio/debugger/debugger-feature-tour?view=vs-2019 (if you're using Visual Studio)

[spare mountain]

do these people live life with a blindfold on

[late burrow]

split that line into more lines so editor specifies function that errors out

[summer stump]

That was suggested a while ago, and would be a good idea

They seem to be ignoring all suggestions though unfortunately

[timid hinge]

problem solved now i have onther one error

is it the same think?

[short hazel]

Yes

[polar acorn]

Not sure what you mean by the 1000 for "how often" but you've got 100,000 entries in the collection, which would make sparse arrays inviable, they'd just be too big.

I think your best bet is ordered dictionaries. Loop over the keys and compare them to your condition, and store the value if it is less than that. When you hit the first value greater than your condition, break the loop and the last thing you stored is the biggest key that isn't over your condition.

[timid hinge]

its on line 166

[polar acorn]

What is line 166

[short hazel]

Follow the same troubleshooting steps. Stack trace to locate the line of code, then check what's null and make it not null

[summer stump]

Do not share code as screenshots, as I have told you three or four times within two days

[late burrow]

too many functions that can error out split them to 10 lines

[timid hinge]

why?

[summer stump]

!screenshots

[eternal falcon]

No

Be mindful, if someone requests your code as text, don't send a screenshot!

[polar acorn]

Something on that line is null but you're trying to do stuff to it anyway.

That is a hella complex line, you should split it into multiple steps for your own sake so you can more easily find what's null

[short hazel]

Cannot copy text from a screenshot to paste it back here, for example

[verbal dome]

Like 6 things on that line could be null

[late burrow]

i miss times when editor said exact character count from where error starts

[timid hinge]

oh sorry about that

[summer stump]

One thing, never use Find
At least do the tag or type variety
Better to drag and drop whenever possible

[polar acorn]

It does for syntax errors. Runtime errors can't have that because the code doesn't actually exist in that state, it's machine code by then

[short hazel]

That's only available for compiler errors, column index info is stripped out from compiled code.
In some cases the debugger tells you what exectly went wrong

[verbal dome]

I think that is Transform.Find

[short hazel]

eg.

[summer stump]

Ah fair. I would still avoid string based search. But yeah. Not as bad

[languid spire]

Do you ever take any notice of anything anyone says?
I told you days ago not to use compound statements and even showed you how to break them down
